Hardware Replacement Project Essay

Assignment: 1 Hardware Replacement Project: Hardware Replacement Project: Your Name Instructors Name Date Assignment: 2 The IT- department in implementing a new CRM solution to its corporate offices. The hardware currently in use is out of date and will not support the CRM application. The hardware must replace prior to deployment. How do the five major variables of project management-scope, time, cost, quality, and risk – relate to this scenario? Scope: Defines what work is or is not included in a project. For example, the scope of a Project for a new order processing system might include new modules for inputting orders And transmitting them to production and accounting but not any changes to related accounts Receivable, manufacturing, distribution, or inventory control systems. Project management Defines all the work required to complete a project successfully, and should ensure that the Scopes of a project not expand beyond what was originally intended. Time: Time is the amount of time required to complete the project. Project management Typically establishes the amount of time required to complete major components of a Project. Each of these components is further broken down into activities and tasks. Project Management tries to determine the time required to complete each task and establish a Schedule for completing the work. Cost: Is based on the time to complete a project multiplied by the daily cost of human Resources required completing the project. Information systems project costs also include The cost of hardware, software, and work space. Project management develops a budget for The project and monitors ongoing project expenses. Risk: Refers to potential problems that would threaten the success of a project. These Potential problems might prevent a project from achieving its objectives by increasing time And cost, lowering the quality of project outputs, or preventing the project from being Completed altogether. We discuss the most important risk factors for information systems Projects later in this section. Assignment: 3 What consideration must be applied when selecting projects that deliver the best business value? A project is a planned series of related activities for achieving a specific business objective. Information systems projects include the development of new information systems, Enhancing existing systems, or projects for replacing or upgrading the firm’s information Technology (IT) infrastructure. Project management refers to the application of knowledge, skills, tools, and techniques to achieve specific targets within specified budget and time constraints. Project management activities include planning the work, assessing risk, estimating resources required to Accomplish the work, organizing the work, acquiring human and material resources, assigning Tasks, directing activities, controlling project execution, reporting progress, and analyzing the Results. As in other areas of business, project management for information systems must deal With five major variables: scope, time, cost, quality, and risk. What factors that influence project risk? Results of not meeting or achieving the goal the company needs. Some systems development projects are more likely to run into problems or to suffer delays Because they carry a much higher level of risk than others. The level of project risk is Influenced by project size, project structure, and the level of technical expertise of the Information systems staff and project team. The larger the project—as indicated by the What strategies would you recommend for minimizing the projects risks? In a parallel strategy, both the old system and its potential replacement are run Together for a time until everyone is assured that the new one functions correctly. The old System remains available as a backup in case of problems. And the direct cutover strategy Replaces the old system entirely with the new system on an appointed day, carrying the Risk that there is no system to fall back on if problems arise. Minimizing the projects risks would be difficult for me I would really have to hire someone that would be more of a High Tech IT- to be sure that all the risks that may come with adding new software systems would be easy to manage for a lower tech that may be in house of the company, in my opinion when you change the entire systems to be updated there has to be a happy medium. In order to keep all systems functioning the way they need to. Data for any company is very important in keeping it safe from and harm during the new change processing as well. The strategies I would consider would be to make sure that every data within the company had a storage space to keep it in to avoid the risks of losing it, I would also make sure that we would start with a small portion of the updating to make sure that this new operating system would work for the company as well. There are many OS available to bigger company’s and provide very good updates for the company’s new systems that can and do run excellent without having a lot of risk or problems, but it was tested before actually putting in to action and use. This gave the company a better view and was able to train the employees that were going to need to know, fix, and keep the main performance and upkeep of them. Any organization can add a new OS’s, but the key is learning to the best of your ability to make sure that it will keep the company functioning to its best and completing the goals and requirements it needs to keep them in business as well. Also if you keep your organization with the right level of systems updating then you can be sure that you don’t need to hire a High tech IT service to have the up keep kept up and you are more likely to be able to train your existing IT, this will also save costs because you will not need to constantly call the high tech when you encounter a small problem. Keeping the operating system to the level of the project and the risk would most likely be less than having a system that would be overboard to what each company needs.

Relative Reactivity of Alkyl Halides

Relative Reactivity of Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions, and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution, or unimolecular displacement. In the first step of the mechanism, the carbon-halogen bond breaks and the halide ion leaving group leaves in a slow, rate-determining step to form a carbocation intermediate.The carbocation intermediate is then immediately detained by the weak nucleophile in a fast, second step to give the product. A solution of ethanol with some silver nitrate may be added provided the weak nucleophile – the alcohol. If an SN1 reaction occurs, the alkyl halide will dissociate to form a carbocation, which will then react with the ethanol to form an ether. Since there is not a strong nucleophile present, the cleavage of the carbon-halogen bond is encouraged by the formation and precipitation of silver bromide.The halide ion will combine with a silver ion from the silver nitrate to form a silver halide precipitate, which will advise that a reaction has occurred. + AgBr + NO3- Figure 1: The SN1 mechanism of 2-bromo-2-methylpropane and silver nitrate. The nucleophile would have been ethanol while the silver nitrate would have disassociated to form a silver halide precipitate. The more stable the carbocation, the quicker the reaction. Therefore, SN1 reactions desire tertiary substrates most, followed by secondary, and lastly primary.Because the strength of the nucleophile is unimportant, an ionizing solvent is needed. Water is the best solvent, followed by methanol, ethanol, propanol, and lastly acetone. In experiment two, the tertiary 2-bromo-2-methylpropane was the most favored reactant followed by the secondar y 2-bromobutane, the primary 1-bromobutane, and the primary 1-chlorobutane. This order is determined by whether the molecule is primary, secondary, or tertiary. 2-bromo-2-methlypropane + AgNO3 + (CH3)2CO AgBr + ethyl-t-butylether + isobutylene Figure 2: The SN2 mechanism of 2-bromo-2-methlypropane with AgNO3 in (CH3)2CO.The SN2 reaction mechanism is a one-step, bimolecular displacement in which the bond-breaking and bond-making processes occur simultaneously. The SN2 reaction requires a strong nucleophile. The order of reactivity is the opposite of the SN1 reaction because the nucleophile must attack from the back, and is favored with the least steric hindrance. The halide attached to a primary carbon is easier to attack from the back. In experiment one, the 1-chlorobutane was the most favored reactant followed by the primary 1-bromobutane, the secondary 2-bromobutane, and the tertiary 2-bromo-2-methylpropane.This order is determined by whether the molecule is primary, secondary, or tertiary. â€Å"SN2 reactions are particularly sensitive to steric factors, since they are greatly retarded by steric hindrance (crowding) at the site of reaction. In general, the order of reactivity of alkyl halides in SN2 reactions is: methyl > 1 ° > 2 °. The 3 ° alkyl halides are so crowded that they do not generally react by an SN2 mechanism. †1 1-chlorobutane and NaI-acetone ——> 1-iodobutane + NaCl (precipitate) In general, weaker bases make better leaving groups.SN1 and SN2 reactions show the same trends, but SN1 is more sensitive. The reactants favored in the SN2 mechanism are the opposite of the SN1 reaction. the primary 1-chlorobutane was most favored, followed by the primary 1-bromobutane, the secondary 2-bromobutane, and tertiary 2-bromo-2-methylpropane.

Five drops of each of the following reagents were added to the test tubes in numer ical order: 2-bromo-2-methylpropane, 2-bromobutane, 1-bromobutane, 1-chlorobutane. Twenty drops of NaI in acetone were added to each test tube, the time of the first drop was recorded, and the tubes were mixed. The exact time of the first sign of cloudiness in each test tube was noted. The exact time of the first sign of precipitation was noted.If no reaction occurred within five minutes, the test tube was placed in a warm water bath. No color change was observed, only a change in cloudiness of the solutions. For part B, the test tubes were rinsed with ethanol and then the same amount of each alkyl halide was placed into each test tube. Twenty drops of silver nitrate in ethanol was added to each of the four test tubes, and the exact time that the first drop was added to each test tube was noted. The exact time of the first sign of cloudiness in each test tube was noted. The exact time of the first sign of precipitation was noted.If no reaction occurred within five minutes, the test tube was placed in a warm water bath. No color change was observed, only a change in cloudiness of the solutions. For part C, four clean test tubes were acquired and numbered 1-4. 1 mL of 1:1 methanol and water was added to the first test tube; 1mL of 1:1 mixture of ethanol/water was added to the second test tube; 1mL of 1:1 mixture of 1-propanol/water was added the the third test tube; and 1 mL of 1:1 mixture of acetone/water was added to the fourth test tube. Three drops of . 5M NaOH and three drops of 1% phenolphthalein were added to each test tube.Three drops of 2-bromo-2-methylpropane were added to each test tube, and the exact time that the first drop was added to each tube was noted. The tubes were swirled, and the disappearance of the pink color was observed. The final color of each solution was yellow. Results Table 2: Reaction times pertaining to SN2 reactions, SN1 reactions, and the solvent effects on SN1 reactions.

The primaries finished first, followed by secondary, and lastly tertiary.The primary 1-bromobutane completed first, followed by the primary 1-chlorobutane. The secondary 2-bromobutane completed third, and the tertiary 2-bromo-2-methylpropane finished last. The 1-bromobutane finished before the 1-chlorobutane because bromine was a better leaving group than chlorine . This is because bromine is bigger and less electronegative than chlorine. Therefore the bromine did not form as tight of bonds with carbon as chlorine, and could more easily leave the group. In experiment B, the results followed the trend hypothesized for SN2 reactions in the introduction.The tertiary finished first, followed by secondary, followed by the primaries. 1-bromo-1-methylpropane finished first because of its tertiary nature. The secondary 2-bromobutane finished second. The primary 1-bromobutane finished third, followed by primary 1-chlorobutane. The rate-limiting formation of the carbocation decided this pattern. The 1-bromobutane finished before the 1-chlorobutane because bromine was a better leaving group than chlorine. In experiment C, the results did not follow the trend hypothesized for the solvent effects on the SN1 reaction.Methanol should have finished first, then ethanol, then propanol, and lastly acetone. The results were the exact opposite; acetone finished f irst, then propanol, then ethanol, and lastly methanol. The boiling points of the solutions were responsible for this result. The bottles containing the solutions must have been left open for a prolonged period of time before use to allow evaporation. The acetone, propanol, and ethanol must have been mainly water, and thus finished earlier than methanol. The first error pertained to experiment C. The results were backwards, and had to have been due to the boiling points of the solutions.The solutions that evaporated the most before the experiment finished quickest because of the ratio of water to the specific solution. The error could have been corrected by remaking the solutions before lab. The second error pertained to experiment B. The experiment was performed twice because the test tubes were not washed with ethanol between uses. The use of water to wash the test tubes sped up the reactions because water was the best solvent for the SN1 reactions. The use of ethanol to wash the test tubes had little effect on the rate of the reactions because it was the third best solvent after water and methanol.Conclusion The purpose of the experiment was to identify the effects that the alkyl group and the halide leaving group had on the rates of SN1 and SN2 reactions, and the effect that the solvent had on the rates of SN1 reaction. The purpose was achieved because the tertiary alkyl group sped up the SN1 reaction most, while the primary alkyl group sped up the SN2 reaction most. The effect of the halide-leaving group was established because bromine was bigger and less electronegative than chlorine, which allowed bromine to leave the group sooner than chlorine due to the less strong bonds of bromine.The solvents’ effect on the rates of the SN1 reaction was due to the encouragement of the cleavage of the carbon-halogen bond, instead of the use of a strong nucleophile. An improvement for the experiment would have been to mix the solvents just before lab to reduce the amount of solvent that boiled off at room temperature. More accurate measurements such as 1 mL measured in the graduated cylinder would have been more precise and consistent than the addition of a specific number of drops. References The SN2 Reaction.

What would be the major product if 1-bromo-3-chloropropane was to react with NaI in acetone? Explain. 1-iodo-3-chloropropane would be the major product. This substitution reaction works best for primary alkyl halides. The bromide ion is a better leaving group than chloride ion. 2. In the reaction of 1-chlorobutane with CN-, the reaction rate is increased by the addition of catalytic amount of NaI. Explain the result. The I- ion replaces the Cl to form 1-iodobutane.The iodo group is a better leaving group than the chloro group and hence the reaction g oes faster. 3. What would be the major product if 1,4-dibromo-4-methylpentane was allowed to react with: a. ) One equivalent of NaI in acetone? Iodide is a strong nucleophile but a weak base, so SN2 is the preferred reaction. Only the bromine on C1 is eligible to undergo SN2, so it will be replaced by iodide. b. ) One equivalent of silver nitrate in ethanol? Silver ion tends to receive a halide ion and leave a carbocation, which means E1 and SN1. If there's only one equivalent, then the tertiary bromide on C4 is the one that will go.The resulting carbocation can give: E1 products 5-Br-2-Me-2-pentene (major, trisubstituted) and 5-Br-2-Me-1-pentene (minor, disubstituted). SN1 product 5-bromo-2-ethoxy-2-methylpentane. 4. What causes the color change in part C? The formation of the acid after the addition of the base NaOH and an acid-base indicator may be visibly observed when the reaction has completed. As the reaction proceeds, for every molecule of alcohol produced, there is one mole cule of acid produced as well. This means that as the reaction proceeds the acid begins to neutralize the base, once enough product and

About Huck

About Huck Although Huck is white, he is poor, which makes him out of touch with civilized society, and although the Widow Douglas attempts to â€Å"sivilize† Huck by giving him the schooling and religious training he has missed, he resists her attempts and maintains his independent ways. He has not been indoctrinated with social values like a middle-class boy like Tom Sawyer has been. Huck’s distance from civilized society makes him skeptical of the world around him and the ideas it passes on to him. He has more practical values than the members of the middle class; for example, he doesn’t care about the Widow’s story about Moses because he â€Å"don’t take no stock in dead people† (2). Huck distrusts and questions the things society has taught him. For example, according to the law, Jim is Miss Watson’s property, but according to Huck’s sense of logic and fairness, it seems â€Å"right† to help Jim. He draws his own conclusions th at would shock white society: Huck discovers, when he and Jim meet a group of slave-hunters, that telling a lie is sometimes the right course of action. Huck is willing and eager to question the â€Å"facts† of life and of human personality, such as the tendency to lie. Though Huck always remains open to learning, he never accepts new ideas without thinking. He is skeptical of social doctrines like religion and willing to set forth new ideas. For example, he doesn’t â€Å"see no advantage† in going to heaven with Miss Watson, especially since he wants to stay with Tom Sawyer (3). Huck speaks in simple terms but is intelligent enough to question society’s value of religious ideas and follow his own heart; he values his friend over a biblical standard of the afterlife. However, Huck is inevitably tainted by the Southern white conception of the world. He genuinely struggles with the question of whether or not to turn over Jim to the white men who ask if he is harboring any runaway slaves. In some sense, Huck still believes that turning Jim in would be the â€Å"right† thing to do, and he struggles with the idea that Miss Watson is a slave owner yet still seems to be a â€Å"good† person. As he spends more time with Jim, Huck is forced to question the facts that white society has taught him and that he has taken for granted. He realizes that he would have felt worse for doing the â€Å"right† thing and turning Jim in than he does for not turning Jim in. When Huck reaches this realization, he makes a decision to reject conventional morality in favor of what his conscience dictates. This decision represents a big step in Huck’s development, as he realizes that his conscience may be a better guide than the dictates of the whi te society in which he has been raised. As a narrator, Huck views his surroundings logically and pragmatically. His observations are not filled with judgments; instead, Huck observes his environment and gives realistic descriptions of the Mississippi River and southern culture. Huck simply accepts, at face value, the social and religious tenets pressed upon him by Miss Watson until his experiences cause him to make decisions in which his learned values and his natural feelings come in conflict. When Huck is unable to conform to the rules, he assumes that it is his own deficiency, not the rule, that is bad. He observes Pap saying he’ll never vote again because a black man was allowed to, but Huck but does not condemn this because it is the accepted view in his world. Huck simply reports what he sees, and this narration allows Twain to depict a realistic view of common ignorance, slavery, and the inhumanity that follows.

Texas History Essay Example | Topics and Well Written Essays - 1000 words

Texas History - Essay Example He further states that the region is called ‘Land of Contrasts’ owing to its variation in landscape since four out of eight geographic terrain making up North American Topography marks the state (3). Schmidly states that the Grasslands stretch from Canada to the High Plains till the prairies, sandy beaches and marshes marking the coastline, in addition, the western region of the state is overshadowed by the mountainous ranges and desert, which are separated by Rio Grande, a major river of Texas (307). He further states that in the east, Big Thickets and Pineywoods represent sections of the forest that stretches all the way till the Appalachians, in the south a subtropical Rio Grande Valley dots the southern Texas, these landscapes meet in Central Texas where the country includes a mixture of grassland, shrubs and forest (307). McComb states that the average rainfall recorded drops from fifty-eight inches per year in the east to eight inches in the west, while heavy snowf alls are a rare commodity but there are records of blizzards on the High Plains (5). He reveals that despite of the southerly breezes the summers are quite hot, during the 1980 summer, the temperature of 105 to 110 were common in the state which permits a prolonged growing season in the south (7). Procter and McDonald state the sufficient archeological evidence exists which confirms the fact that migrants belonging to Asia crossed the Bering Land Bridge forty thousand years ago and became the early occupants of America collectively known as Paleo Indians (3). They divulged the fact that archeologists unearthed the oldest human signs in the state almost thirty thousand year old whose cultural complexes are known as Lano and Falsom suggesting that Paleo Indians made Texas their abode for thousands of years. Foster indicates that early study reveals that the native tribes of Texas exhibited a broad range of cultures and lifestyle, reflected by their abstinence and settlement patterns o ver the state (233). He is of the opinion that most of them were agriculturist who constructed villages near the major rivers, while small proportion of them were dispersed groups whose mean of sustenance were fishing, collecting local plant products and hunting small woodland games. He further stated that spanning the stretches of Central, West and South Texas were semi nomadic groups who moved occasionally to other states of America for subsistence and followed the traditions of Homo Sapiens of the Old World which thrived thirty thousand years ago. Q.2) Identify the important explorers of Texas. What motivated these men to risk their lives in a distant, inhospitable land? Answer) According to Bolton and Barker, Spanish occupation of Texas did not happen by chance, it was a result of a series of pre-planned explorations of the land with the suitability of settlement in mind (1). He suggested that the main reason behind the capture other than the French advances in the region, was t he search of kingdom of Quivira, a part of myth and romances associated with Texas, where crockery was manufactured of precious metals such as those of gold and wrought plate, even their vessels, tips of arrows and lances were made out of gold due to it being in plentiful supply and no other metal were known for its existence along with another myth that the kingdom of Texas has lavishly built towns and buildings where grain grew in such abundance that it was fed to their horses (2). Klos is of the opinion that the European powers made Texas a ‘horse and gun’ junction, French and the English traders traded guns with the Indians in Texas to win over their

Globalization of Financial Markets Essay Example | Topics and Well Written Essays - 750 words

Globalization of Financial Markets - Essay Example The impact on the stock markets themselves is difficult to predict, and could change investments and trading styles in ways that cannot be suggested from this naà ¯ve point (Sabri, 2006). For example, moving all stock exchanges from the physical to the electronic will create what is essentially one grouped exchange, meaning that any differences in the exchanges and their consequences will be eliminated (Sabri, 2006). Additionally, there may be consequences for the NASDAQ because of this conglomeration, as lower performing exchanges are incorporated into the more resilient. It is difficult to say whether this will improve the poorer performers or decrease the impact of the vital markets, but it is evident that there will be a distinct change in market performance (Arshanapalli & Doukas, 2003). The globalization of financial markets will also have inevitable consequences for the way that corporations themselves do business. If financial markets were truly globalized, there would be a need for many corporations to offer a 24-hour trading system to match the state of the exchanges, and thus many would require a greater financial output and labour input (Sachs, 1998). The globalization of financial markets could also lead to a greater amount of competition in many markets, with Eastern companies utilizing cheaper labour sources to provide cheaper services. This could cause corporations a number of problems, and introduce a need to investigate how to further improve profit margins to become competitive on a global scale. (Lahiri, Perez-Nordtvedt & Renn, 2008). Another element for business that is often discussed in the literature is a change in mind set. Along with more physical changes, an increase in globalization will require a number of changes in interaction with foreign m arkets, and understanding differences in financial systems worldwide. Lahiri, Perez-Nordtvedt & Renn (2008) suggest that there are a number of different elements that are required for the success of a corporation in the global market, including an increased appreciation of communication and cooperation, readiness to deal with temporal and cultural differences, and realizing sources of unexpected competition. These all come from an increased diversity in the market and a number of difficulties that come from dealing with previously unknown customers and investors. In conclusion, there are a number of ways in which financial markets are going to need to

Efficient Market Hypothersis Essay Example | Topics and Well Written Essays - 2000 words

Efficient Market Hypothersis - Essay Example While the extent of the validity of these criticisms remains debated, the efficient-market hypothesis (EMH) has held a pronounced influence on political and academic thought. This essay considers the extent that the market, as Warren Buffet claims, functions under irrational processes, or can be explained in rational terms through the efficient market hypothesis. Outline of the Efficient Market Hypothesis (EMH) In its modern incarnation Professor Eugene Fama first articulated the efficient-market hypothesis in the early 1960s during his time at the University of Chicago Booth School of Business. From an overarching perspective, the efficient market hypothesis theory contends that for investors it is impossible to ‘beat’ the market on a consistent basis. The main reasoning behind this notion is that the market will reflect all available information for the particular investment, such that gaining any sort of edge over other investors is made impossible. This contention do es not necessitate that individuals act in rational ways. Indeed, the efficient market hypothesis understands that a number of individuals will both over and under react to available market information. The cumulative impact of these reactions results in market efficiency, as the random reactions will fall proportionally along a normal distribution pattern. In these regards, it’s possible for an individual to be right or wrong about the market, but the market itself is necessarily an accurate reflection of available asset information. Structural Components There are three major versions of the efficient market hypothesis, each of them resting on a different part of a spectrum of efficiency. The first version is the weak-form efficient market theory. Within this perspective all prices on past publically traded assets, including stocks, bonds, and property, already have factored into them all publically available investment information. The semi-strong version of the hypothesis takes this a step further and argues that current asset prices reflect all publically available information and that when new information emerges prices change instantly to reflect this new public information. The third version of the efficient market hypothesis is the strong-form version. The strong-form version of the hypothesis goes even further in that it argues in addition to asset prices immediately reflecting public information, asset prices also instantly reflect insider or otherwise concealed information. Analysis Seminal Literature There are a number of seminal studies that established core elements of the efficient market hypothesis. While Fama first articulated the theory in its modern context, its original formulations were explored as early as the 19th century. Kirman (2009) notes that French mathmetician Louis Bachelier established many of the general tenants of this theory in his ‘Theory of Speculation’ published in 1900. The early years of the 20th cen tury witnessed another prototypical formulation of this perspective in the random walk model; this was a notion that stock prices operated through random steps and as such gaining a long-term predictive edge was

Hinduism and Judaism Essay Example | Topics and Well Written Essays - 1000 words

Hinduism and Judaism - Essay Example There are interesting similarities and differences in their foundational teachings that show some of the elements that unite people, and some of the ways in which cultural context informs religious development. Hinduism traces its roots back to approximately 2500 B.C. It was not a religion that began with one particular historical event, but was rather a gradual development of beliefs by peoples in the Indus Valley (Zaehner, pg. 15). Its sacred literature has two categories: sruti and smriti. The sruti were heard, or divinely revealed, and include the Vedas (the most ancient Hindu scriptures), the Upanishads, the Brahmanas, and the Aranyakas. The Vedas contain the creation account, regulations for sacrifices, and prayers. According to Hindu tradition, these texts were secretly taught by a prophet to a disciple (David S. Noss, 55). The smriti are texts that were remembered or passed down orally. The difference is that these were written by humans rather than by the gods. The smriti consist of the epics, the Sutras and the Puranas. The epics are long poems about events in the lives of heroic warriors. The Sutras relate to such ideas as dharma, yoga, and Vedanta. The most significant of these was the Laws of Manu, or the Manusmriti, which concerned proper law and conduct for Hindus. The Puranas are mythological writings, containing the stories of the gods and goddesses (Knott, pg. 24-25). The Indus Valley civilization cohered around two cities, Mohenjo-Daro and Harappa. Between 2500 and 2000 B.C., the nomadic Indo-Aryans began to migrate into this area, just as the Indus Valley peoples began to disappear. The Vedas were the scriptures of the Indo-Aryans and are most commonly acknowledged as the basis for Hinduism, and they are also said to be Hinduism's supreme authority (Morgan, pg. 32). The Vedic conception of rita, or cosmic order, later served as the basis for the ideas of dharma and karma. The gods served as guardians of this idea of rita and had to be propitiated regularly by sacrifice. (Morgan, pg. 33). And so with the idea of sacrifice came a collection of regulations and technicalities for the sacrifice process (Kinsley, pg. 92). During this time, the priesthood came to assume a good amount of power in society. Such new doctrines as the four stages of life, the idea of transmigration, and the origins of the caste system (Morgan, pg. 48). While in its foundat ional stages, Hinduism had claimed that the soul could die, either on Earth or even in heaven, but this change had the soul being reborn in an endless cycle, seeking release, or moksha from this unending existence. Despite the fact that Judaism started far from Hinduism, there are many striking similarities to complement the differences between the two faiths. According to such sources as the Tanakh and the Talmud, the Jewish faith is based on a covenant between God and Abraham, established approximately in 2000 B.C., and renewed between God and Moses around 1200 B.C. Unlike Hinduism, Judaism is monotheistic (Huns Kung, pg. 88). Like Hinduism, Judaism relies on its texts and traditions to provide its central authority. Like the Vedas, the Torah underwent a brief period of

Catatech - Case Study Example In order for Catatech to keep up with the competition, it will need to adapt to this new introduction while doing business or its insistence with sticking with the traditional methods may just prove to be its downfall. For the firm to do this, it has to first establish the objectives that the firm has set for themselves so as to identify how the introduction of E commerce would assist it in achieving these objectives (Kotler, 2009). The main objective of the firm is to maintain and enhance its position in the industry as one of the leading providers in Professional measurement tools for electricians across the globe. The other objectives include, the strengthening of their financial standing to avoid any economic burdens which can be done by the reduction of various costs without affecting the quality of the product, to increase its market size in the various regions where they are located including Madrid and to ensure the firm is in a position to maintain a successful path as a lea ding business in the future. The measures of outcome that can be used to indicate whether these objectives have been attained are not difficult to calculate. With regard to becoming the leading firm in the industry they are based in, one only has to look at the market share value taken by the firm in compared to others in the same business (Kotler, 2009). When Catatech has the largest market share value, it can be said that its main objective has been achieved. With regard to strengthening the company’s finances as well as increasing its market size, these objectives can use the company’s various records relating to these topics which in this case would be financial records and progress reports over the years on the growth of their market base. Accountability has to be considered as well to ensure that those responsible for achieving these objectives are putting an effort into it. Ensuring the company’s success as a leader in its industry will be up to everyone in the firm but the executive board that is in charge of the major decisions that will be made can be said to be held accountable for this task. The finance department and the marketing department will be held responsible for the objectives of cutting costs effectively and ensuring market growth (Tkacz & Kapczynski, 2009). There are also several external and internal factors that may affect the achievement of these objectives as well such as the developments that are being made in technology, the arrival of new firms in the industry and the attitude of the executive staff at the organization as well, which may prove to be a hurdle to the process of keeping the organization in stride with various new developments in the business world. There are a number of constraints as well that may limit the achievement of these objectives such as the availability of manpower with the technical know how to introduce these new technologies to the firm, the issue of underplaying the independence th at the various local acquisitions enjoy at the moment which also brings about the question of finances and who will handle those received via the E commerce project. There are various resources that can be said to be available to the organization at the moment, and that includes the organization has the financial resources to set up the new structure (E commerce) if they are willing to do so. The employees available in the United States can also lend a hand to solve the problem of technical know how

Business Continuity Planning Essay Example | Topics and Well Written Essays - 500 words

Business Continuity Planning - Essay Example Thus there has emerged a need for ‘Business Continuity Planning’ (BCP). Any natural or unnatural disaster can always disrupt a business activity either for a short or a longer duration. It has now become essential to foresee such eventualities and have concrete plans to handle such situations. One of the prime examples of such a scenario was the terrorist activity in which the World Trade Centre was destroyed in New York which posed an immediate threat to the business concerns in that location. However many of the organizations in the area had adequate backup and continuity plans in place which helped them to recover (Safeguard). An ideal BCP begins by identifying the ‘applications, customers and the locations which an organizations needs to keep functioning in face of any disruption and the time frame involved in the execution of the backup plan’ (Mphasis). The identified applications and services need to be delivered continuously even during the disruptive phase and any good BCP endeavors to pre plan and enforce such infrastructure, regulations and methods without fail under continuous supervision and testing. Resources in order to achieve continuity need to be identified and categorized according to priority beforehand. Such resources must include ‘personnel, finance, information, equipment, legal counsel, accommodations and infrastructure protection (Safeguard). A good BCP plan in force enhances the reputation and the confidence within as well outside a business organization. BCP is initiated by a special governance sector or an exclusive department in the organization which takes overall control for planning, finance, execution, auditing and testing of the program. It conducts a ‘business impact analysis to identify the organization’s mandate and critical services or products’ (Safeguard). It then prioritizes different

Law of Contract, Assignment Case Study Example | Topics and Well Written Essays - 2250 words

Law of Contract, Assignment - Case Study Example This does not mean that there must be an exact subjective matching of the internal thoughts of the two parties. What the law looks for is outward evidence of what the parties agreed or what has been termed the 'external indicia of agreement'.1 This means that even if the parties did not have the same agreement in mind, if their actions, from an objective standpoint could be said to demonstrate an agreement, then a contract has been formed.2 This follows the sensible approach that 'commercial contracts cannot be arranged by what people think in their inmost minds. Commercial contracts are made according to what people say'3 What this means for our problem question is that, while searching for the consensus in idem between Riz and Jatinder, we look at how they acted in the above negotiations. To form a contract, all you need to identify is an offer and an unqualified acceptance of it. The question here is whether the advertisement in the magazine constituted an offer. Offers may be express such as 'I'll give you 50 for that skirt', or they can be implied such as hading over the fare as you get on the bus. In both cases it is open for the offeree to accept the offer. This will conclude the contract. However, despite the ease of making offers or implied offers, some actions will not form offers at all but merely invitations to treat. An invitation to treat may look like an offer but if you look closely, there has not been agreement on the essential factors of the contract, there has just been some words passed that would entice or make it easier for the other party to make a suitable offer. For example, in Harvey v Facey4 one party asked the other what would be the lowest cash price they would be willing to sell a property in Jamaica. The other party replied that it would be 900. The first party then telegraphed them 'We agree to buy BHP for 900 asked by you'. The owners argued that they had never offered to sell the property and the agreed with this. It is also generally accepted that advertisements and announcements to the public at large are not intended to be offers but merely invitations to treat. This is for the simple practical reason that if too many people responded to the advertisement, the advertiser could be placed in a position of breaching limitless contracts. Therefore, unless words specifically forming a contract are used, an advertisement will be deemed to be an invitation to treat and not an offer.5 b. Riz's offer of 5,000 When Riz saw the advertisement he called Jatinder on the phone and offered her 5,000 for the car.

The Future of Criminology Essay Example for Free

The Future of Criminology Essay Over the past several years criminology has made leaps, bounds, and advances to enhance capturing criminals. Due to the increasing technology at the fingertips of criminals and terrorists law enforcement has been forced to step of their resources and intelligence. The government is constantly faced with new methods people have created to commit crime. Technology is infiltrating every aspect of the criminal justice system, from the investigation to the prosecution of crimes and even to attempts to predict them. What steps is law enforcement and the government taking to ensure our safety and to catch the criminals and terrorists? Biometrics After the attacks on 9/11 the government discovered America was not truly prepared for anything. America lacked the technology and resources to stop terrorist’s attacks. Suddenly, the United States government became acutely aware that it didn’t know exactly who was passing in and out of the country. After 9/11, the U.S. Congress decided we must have some way of securing our borders. What did the government do to try to protect the nation? They looked into security measures such as biometrics. â€Å"Biometric is the most secure and convenient authentication tool. It cannot be borrowed, stolen, or forgotten and forging one is practically impossible. Biometrics measure individuals unique physical or behavioral characteristics to recognize or authenticate their identity. Common physical biometrics include fingerprints, hand or palm geometry, retina, iris, and facial characteristics. Behavioral characters characteristics include signature, voice, keystroke pattern, and gait. Of this class of biometrics, technologies for signature and voice are the most developed† (Biometric Security Technology, n.d.). Today, our identities are verified almost exclusively by things that you carry with you and things you remember.  Driver’s licenses social security cards, birth certificates and passports are common documents people carry with them, and passwords and PINs are common security measures people remember. Physical identification is easy to fake, and passwords are easily cracked by hackers, who then have nearly unfettered access to our credit cards, bank accounts, and personal data. People make fake driver’s licenses, social security cards, birth certificates and even death certificates. Hackers only need limited information about a person to steal their identity. It is mind boggling to think what little data criminals need that can turn a person’s life upside down in a matter of seconds. Something needs to change and biometrics could be that change. Biometrics are a fundamental shift in the way people are identified. Unlike traditional identification which individuals must either remember or carry with them, biometrics is the individual, it is a part of who you are so to speak. Fingerprints, voice analysis, iris patterns, vein matching, gait analysis, and so on. Such traits are unique to an individual and often, though not always, incredibly difficult to fake. â€Å"United States government has poured money into research, development, and acquisition of biometric identification systems. The Department of Homeland Security has spent over $133 million on biometrics since 2003, and the Defense Department is predicted to spend $3.5 billion on the technology between 2007–2015. The Federal Bureau of Investigations has rapidly expanded its fingerprint database and is currently developing a more sophisticated system that will add iris scans, palm scans, and facial recognition to the mix† (De Chant, 2013). Just because biometrics cannot be lost or misplaced does not mean they cannot be misused. Privacy concerns loom large with biometrics. A biometric security measure by itself is not threatening, though they are easily linked to other, potentially sensitive information, and that’s when people grow uneasy. Biometrics are a part of person and not something that can easily be discarded like a Facebook page or a password. This causes a lot of anxiety for some people. The government would have part of everyone on file at their disposal and would it always be used correctly or will American’s become violated by this extra power the government would have? There is already a lot of mistrust in the government it would be difficult to get the American nation as a whole on board with the government having access to our fingerprints, retina’s, faces, and palms. There are people  even in our criminal justice system that abuse their power and give out information that should not be given to certain people, who is to say that same would not happen with should vital information as biometrics. Spyware As rates of cybercrime continue to increase exponentially, law enforcement agencies will have to enhance their cyber-defenses to effectively fight online attacks. New technologies promise to play an important role in this battle for cybersecurity. The war on cybercrime and cyberterrorism has given a major boost to the IT and security industries. In the coming years, the fields could experience even greater growth, possibly generating hundreds of billions of dollars in the US alone. Cyber criminals can be computer geeks looking for bragging rights, to businesses trying to gain an upper hand in the marketplace by hacking competitor websites, from rings of criminals wanting to steal your personal information and sell it on black markets and even spies and terrorists looking to rob our nation of vital information. In this day and age of advanced technology, we have become accustomed to all the benefits that computers give us in terms of convenience. While most of us would never want to g o back to doing things the old fashioned way, it is very important to be aware that anyone can become a victim of cybercrime. â€Å"To effectively detect and deter cyber criminals, it is vital for our law enforcement agencies and our legal community to look beyond our nation’s borders and work with their international colleagues in order to have a global framework of cybercrime statutes. One of the new devices to help detect cyber criminals is a Wi-Fi Investigator. The Wi-Fi Investigator is a tool designed to help law enforcement officials specify locations in order to apprehend suspect devices, including laptops and smartphones. Another featured gadget produces powerful magnetic pulses in order to instantly erase sensitive data in the event of a security breach† (Brown, 2010). Another useful tool for law enforcement is the Global Positioning System or GPS. This is used to help track criminals on probation and parole. This can also be useful in court to show a suspects whereabouts during trial or in tracking down a kidnapped victim. The GPS has become a vital part of an investigation and something that some investigators may even rely on. The same can be said for cellphones since most of them now days are equipped to tell your location as well. Tools and devices are not the only thing that is  used to try to deter cybercrimes, there are laws in place as well. Recently, President Obama calls for a new law for cybersecurity. â€Å"The new cybersecurity effort came a day after Mr. Obama called for legislation to force American companies to be more forthcoming when credit card data and other consumer information are lost in an online breach like the kind that hit Sony Pictures, Target and Home Depot last year. Concern about cybersecurity has increased after the hacking of Sony in December, which the United States government says was the work of the North Korean government. The president said that breach and an attack on the United States Central Command’s Twitter account proved the need for an overhaul† (Hirschfeld Davis, 2015). The cybersecurity measure Mr. Obama envisions would encourage companies to share threat information such as Internet Protocol addresses, date and time stamps, and routing information with the Department of Homeland Security, which would swiftly pass it on to other government agencies and industry groups voluntarily formed to share such material. Companies would get â€Å"targeted liability protection† for doing so, as long as they took steps to protect consumers’ personal information (Hirschfeld Davis, 2015). â€Å"President Obama also called for law enforcement tools to combat cybercrime, including to prosecute the sale of botnets, computer networks created to carry out cybercrime, and to give courts power to shut down those involved in denial of service attacks and other fraudulent activities† (Hirschfeld Davis, 2015). Fighting cybercrime is not just the responsibility of the government it is everyone’s responsibility. Anyone at any time can be attacked by a cybercriminal there is no limits when it comes to cybercrime. The government and law enforcement does their best to protect everyone but it is difficult to protect against someone you cannot see. There is still concerns that maybe technology is trying to take over good old fashion police work such as patrolling and even investigating itself. Is the government looking for the quick technological fix rather than to invest in what it takes to get communities to collaborate on their own safety? The problem is an over-reliance on technology with too little recognition that policing is primarily a people business. Law enforcement and local communities often see technology as a panacea to make communities safer without asking the hard questions. While technology is good to have and it does help to solve some cases it will never replace a police officer. People  find safety and security when they actually see someone protecting them. People need that reassurance. DNA Collection â€Å"The Federal Bureau of Investigations maintains a national DNA database known as the Combined DNA Indexing System or CODIS. The pilot program for what became CODIS started with fourteen state and local laboratories. Today, there are over 180 public law enforcement laboratories that use CODIS. The FBI Laboratorys CODIS program allows federal, state, and local crime laboratories to store, search, and share DNA profiles electronically† (The DNA Act, 2015). The practice of taking DNA samples from convicted criminals is now largely uncontroversial. The courts have routinely upheld laws that authorize DNA collection from both current and former convicts, and the resulting databases of DNA have become powerful tools to analyze forensic evidence collected from crime scenes. The databases help to clear innocent suspects and redirect law enforcement officials away from unproductive investigations. They also help to convict guilty criminals and clear the wrongfully convicted. A trend that is causing significant debate is gathering DNA samples from people who are arrested but not convicted (Berson, 2009). â€Å"About 20 states and the federal government have passed legislation that requires DNA collection upon arrest. This legislation has raised concerns that crime laboratories may be unable to manage an influx of samples from a new source and that preconviction DNA collection may violate Fourth Amendment privacy guarantees. Some people worry that collecting DNA creates the potential for abuse of genetic information stored in databases. Others point out that the federal and state privacy laws and penalties that apply to crime labs are stringent far more stringent than the rules governing private entities that collect blood and saliva for medical or insurance purposes† (Berson, 2009). Although some states limit preconviction DNA collection to violent offenses or sex crimes, other states include all felonies, and some extend the requirement to misdemeanors as well. States legislation requiring preconviction DNA collection varies. Variations include the types of crimes for which samples are collected, applicability of the law to juveniles and procedures for deleting profiles. Some state laws have faced Fourth Amendment challenges in court. â€Å"The Fourth Amendment ensures that [t]he right of the people to be secure in their  persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized† (The DNA Act, 2015). This is where the government will continue to have problems, most American’s live by the Amendments that the United States was founded upon. The Amendments were put in place to give the government limits and when it comes to mandating DNA the government appears to have reached its limits. Conclusion In conclusion, the government and law enforcement have many challenges to face and overcome in the new age of technology. Technology also makes it easier for criminals from around the globe to connect and partner with each other to pull off financial frauds, and the anonymity of the web can make it more challenging to locate and stop online perpetrators. There are legal obstacles as well as ethical obstacles that the government and law enforcement must overcome. At every corner there is a potential for a crime to happen whether it is a person’s credit card, a computer, a bank, a smart phone or even a car. Cybercrime is a growing field and one that is hard to combat with all the technology. The problem the government is facing is what is considered too invasive and what is going too far to protect our nation? References Berson, S. (2009). Debating DNA Collection.

The Lord of the Flies is just a simple, happy ending Essay Example for Free

The Lord of the Flies is just a simple, happy ending Essay Adventure story. It is about children, for children and told from their perspective To what extent do you agree with this? Do you think being a savage; killing, hunting and fighting represents a simple adventure story? The first two chapters of this novel may show innocent and young boys on an island where no fear is held, and maybe that is what it is; referring to the original sin. Which is a story from the Bible showing that everyone is born with evil inside them and it seems that the island has brought this out of the boys. You may be thinking, what about Piggy and Simon? The amount of conflict between the boys increased throughout the book. It started between Jack and Piggy, Jack through insults at him such as Shut up yah fatty! and Piggy stated things directed towards Jack in the form of an insult too, You and your blood Jack Merridew! and then Piggy just refers to Jack as him when Jack leaves Ralphs leadership. Adventure books arent supposed to have arguing, all the boys are supposed to get along! During chapter four, Golding shows that its not only Piggy that Jack hates, but Ralph too, splashing and laughing are just about enough to bring them back together again. At the start of the book it seems a happy adventure as all the boys do get along and listen to Ralphs rules but things start to change as Jack realises theres no point in listening to Ralph as he wanted to be leader all along. As Ralph is leader and made rules for the other boys, calling an assembly, this shows the maturity in the book and his adult characteristics. He seemed to handle things well but then knew he could not think as well as Piggy. Jack shows the immaturity on the island as he treats everything as a game. When the boys had been showing a role-play of their hunt and Robert was the pig, Jack had become quite aggressive hurting Roger, but afterwards all he said was, That was a good game. And when he left the others he said, I dont want to play with Ralphs lot anymore. When Jack first entered the island he was a fair skinned boy who attended the choir and was thought of as a leader, so he didnt take it well when Ralph was chosen as leader instead of him. So to make things even he was made leader of the hunters. At first Jack grimaced distastefully at the touch of blood. This then changed and he had a sharpened stick at one endtattered shorts held up by a knife belt. Does this show an innocent choirboy from an adventure story? Simon was Goldings way of expressing nature in the novel and when the boys killed Simon, they did not as they thought kill the beast but they let the beast out and killed hope and peace. Piggy and Simon were the means of civilisation. Piggy was the only one besides Ralph who stood up to Jack and he was the one who always remembered rescue, hope, signal fire and innocence. When the savages took away Piggys glasses they also took away civilisation and soon after that they took away his life. Adventure stories always end with a happy ending so how could Lord of the Flies be an adventure story? Unless Ralph is being hunted down is happy. I suppose in away it is happy because Ralph received what he had wanted from the moment they set foot on the island; rescue. The ending was ironic as all the way through Ralph had wanted his fire and depended on signal and Jack had been the same about hunting. They both got what they wanted as they were rescued by Jack hunting down Ralph with a fire. Putting all my points together I have come to the conclusion that The Lord of the Flies novel is surely an adventure but not the simple, innocent little boy type as it involves hunting, death, fighting and conflict. It shows the break up of society, lack of civilisation, evil and sin. But on the other hand it shows sunlight, fun, games, nature, happiness and laughter. Although the simple adventure part of this novel would show little boys stuck on an island having fun and trying to be rescued and would not add in the death and arguments.

Biocompatibility Study of Lactobacillus Casei

Biocompatibility Study of Lactobacillus Casei BIOCOMPATIBILITY STUDY OF LACTOBACILLUS CASEI ISOLATED FROM CUCUMBER AND EVALUATION OF PROBIOTIC EFFECTS IN THE HUMAN GUT NANNU SHAFAKATULLAH* and M. CHANDRA Abstract: Probiotics are live microorganisms introduced orally in the gastrointestinal tract (GIT) that are able to contribute positively to the activity of intestinal microflora and therefore, to the health of its host. A variety of probiotic supplements are currently available in the market which target towards improving the balance and activity of the intestinal microflora. Probiotics must have robust survival properties in the gut in order to exert any beneficial health promoting properties. Many in vitro properties, such as adhesion, co-aggregation, aggregation, hydrophobicity, resistance to pH, bile, etc., are usually investigated to determine if a specific selected strain would be suitable as a probiotic. Lactobacillus casei has been isolated from raw cucumber and identified based on phenotypic and biochemical characteristics. The isolate was studied for its survival at acidic pH, bile salt, intestinal juice, gastric juice, co-aggregation, aggregation, different NaCl concentrations, the ir action against pathogens, and resistance to antibiotics. The organism has shown well resistance to antibiotics, gastric acids and bile digestion and also exhibited good adhesion to intestinal mucosa and aggregation properties. Key words: Biocompatibility, cucumber, gastrointestinal tract, Lactobacillus casei, probiotics Introduction: Probiotics are defined as â€Å"live microorganisms which when administered in adequate amounts confer a health benefit on the host†1. The use of probiotic bacteria for the health of human has been increased from the last decade due to the increased research on benefits of the probiotics for human. Knowledge of gut health and awareness of general health consciousness in human leads to the search of new probiotic bacteria2-7. It has been proved that irritable bowel syndrome, inflammatory bowel disease, and antibiotic-induced diarrhea that occur due to the imbalance in the intestinal microflora can be reversed by the intake of probiotics.Lactobacillus species are â€Å"Generally Recognized as Safe† (GRAS) microorganisms and they are the most commonly used microorganisms as probiotics and are the most desired intestinal microflora. It is important to study the biocompatibility of the lactobacillus species before using them as probiotics. Acidic pH, bile salts, and gastric and intestinal juice in the gastrointestinal tract (GIT) are the major stress factors that the probiotics should overcome in order to survive in GIT. Other than their survival capabilities, the probiotic microbes consumed should possess the capacity to adhere and colonize in the gastro intestinal tract. More the adherence capacity of the probiotics more is their chance to retain themselves in the GIT and provide positive effect to the consumer. In accordance with the FAO/WHO8 guidelines in order to prevent the transmission of antibiotic resistance genes from the probiotics to the intestinal pathogens it is recommended that the antibiotic resistance/susceptibility pattern of every probiotic strain (including bacteria with GRAS status) is to be determined. Due to the development of antibiotic resistant pathogens there is increased interest in the alternative antimicrobial strategies for treatment and prevention of infections by using probiotics and their antimicrobial metabolites. Hence, antimicrobial activity against pathogens is a desirable property of a potential probiotic strain. The present study was aimed at isolation, identification, characterization and biocompatibility study of the Lactobacillus strain isolated from cucumber. The biocompatibility properties were investigated throughin vitro assays. Material and Methods Isolation and Identification of Bacteria Fresh cucumber juice was prepared and 1ml of this was serially diluted to 10-5 to 10-6 and inoculated 0.1 ml on to lactobacillus MRS agar plates and incubated at 37 °C for 24-48 hours anaerobically. Gram’s staining, catalase activity, gas production from glucose, acid fast test, MRVP test, gelatine hydrolysis, oxidase test, growth in different NaCl was determined according to methods for lactic acid bacteria9-10. The identification work was done according to the methods described in Bergey’s Manual11 and the Prokaryotes. All the strains were maintained by weekly sub culturing from 48hrs MRS agar cultures. Growth characteristics at different temperature were monitored for 7 days period. Production of ammonia from arginine was done according to the method described by Abdel-Malek and Gibson12, Nitrate reduction was done as described by Gerhardt et al., 13. The isolates were maintained in MRS broth, stock cultures were stored on agar slants in refrigerator and also freez e dried and stored for longer period. Growth at acidic pH The growth behavior of culture isolate was observed at acidic pH to find the acid tolerance capacity of organisms. The Isolate was inoculated in MRS broth with pH 2 and 3 and incubation was done at 37 °C for 48-72 hrs. During these incubation time cells growth was observed and results were recorded. Transit Tolerance: 1. Simulated Gastric Juice The simulated gastric juice was prepared freshly by suspending pepsin 1:10000 (3g/L) (SRL) in sterile NaCl (0.5%) and the pH was adjusted to 2.0 and 3.0 respectively. This was filter sterilized using 0.45 µm filter. The L. casei was grown in de Man, Rogosa and Sharpe (MRS) broth at 37 °C for 24 h and centrifuged at 2,500 Ãâ€" g at 4 °C for 10 min. The collected cells were resuspended in sterile saline (0.5% NaCl) and inoculated into the simulated gastric juice (pH 2.0 and 3.0) at 108 cfu/ ml. The test was done in triplicates. Because the pH in the human stomach ranges from 1 (during fasting) to 4.5 (after a meal) and food ingestion can take up to 3 h, tolerance was assayed by determining the total viable count at 0, 1.5 and 3-h incubation in simulated gastric juice (pH 2.0 and 3.0). 2. Simulated Intestinal Juice The simulated intestinal juice was prepared freshly by suspending pancreatin (1g/L) in sterile NaCl (0.5%) and adjusted the pH to 8.0. This was again filter sterilized by using 0.45 µm filter. 1ml of the suspension of the L. casei was inoculated into 9ml of simulated intestinal juice (pH 8.0) and incubated at 37 °C. The test was done in triplicates. The survival rate was assessed by determining the total viable count at 0, 2, 4, 6 and 8hrs of incubation. 3. Bile Tolerance Bile plays an important role in the survival of bacteria in the small intestine. Food remains in the small intestine for around 4-6 hours14 till it gets absorbed. The L. casei was screened for its survival at different bile concentrations. The organism was inoculated into 10 ml MRS broth in test tubes and incubated at 37 ºC overnight in anaerobic condition. 100ÃŽ ¼l of active culture was inoculated into fresh MRS broth tubes with pH 6.5 containing 0.3%, 0.5% and 1.0% bile (CDH India). The bacterial survival was measured by MRS agar colony count by taking 100ÃŽ ¼l culture for 0, 30, 60, 90 and 180 min and aliquots spread onto MRS agar plates to calculate the CFU/ml. The experiment was determined in triplicate to calculate intra-assay variation. CFU/ml was recorded. Aggregation (Del Re et al., 2000) Aggregation assay was performed by growing the isolates in MRS broth for 24 hours anaerobically at 37oC. The cells were harvested by centrifugation at 5000 rpm for 15 min, at 4oC. The cells were washed twice and re-suspended in phosphate buffered saline (PBS) to give viable counts of approximately 108 CFU/ ml. Four ml of the cell suspension was mixed for 10 seconds in a sterile tube to determine auto aggregation during 5h of incubation, at room temperature. The upper suspension was used in each hour by transferring 0.1ml to another 3.9ml of phosphate buffer solution, and the optical density at 660nm was measured. Tests were carried out in triplicate and the results were averaged. The auto aggregation percentage was calculated by the formula: 1- (At/A0) X 100, where, At represents the absorbance at time t = 1, 2, 3, 4 or 5, and A0 the absorbance at t = 0. Aggregation abilities of microorganisms were screened by visual observation. Co-aggregation The bacterial cells were harvested by centrifugation at 5000 rpm for 15 min after incubation at 37 °C for 18h, washed twice and resuspended in phosphate buffered saline (PBS) to give viable counts of approximately 108 CFU /ml. Equal volumes (2 ml) of each cell suspension were mixed together in pairs by vortexing. Control tubes were set up at the same time, containing 4 ml of each bacterial suspension on its own. The absorbances at 660 nm of the suspensions were measured after mixing and after 5 h of incubation (6-9). The percentage of co-aggregation was calculated using the equation Handley et al. (1987) as, Co-aggregation (%) = [(Ax + Ay) /2) A (x+ y)] / [(Ax + Ay)/ 2] Ãâ€" 100 Where x and y represent each of the two strains in the control tubes, and (x + y) the mixture of isolate tested for co-aggregation. Antibiotic Sensitivity test Antibiotic sensitivity test of the isolate was performed by standard disc diffusion method (NCCLS 1999) towards thirteen antibiotics. The pure culture of L. casei suspension was spread on the MRS agar plates to form a uniform smear. Selected antibiotic discs were aseptically transferred on to the seeded plates. The diameters of the zone of inhibition were measured using antibiotic zone scale (Himedia India) after 24 h of incubation. The experiment was repeated thrice and the average inhibitory zone diameters were compared with the standards provided by the National Committee for Clinical Laboratory Standards. Diameters of inhibition zones were measured and results were expressed as sensitive, S (≠¥ 21 mm); intermediate, I (16-20 mm) and resistant, R (≠¤ 15 mm), respectively according to that described by Vlkovà ¡ et al., 15. Antimicrobial Activity Test Agar well diffusion method16 was used to determine the inhibitory capacity of the L. casei against pathogenic strains such as Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus and Bacillus subtilis. The isolate and pathogenic strains were incubated in MRS agar medium at 37 °C for 24 to 48 h. Result and Discussion Physiological and Biochemical Characterization The isolate was subjected to Gram’s staining and it was examined under light microscope. The strain gave blue- purple color with staining; hence it was Gram positive bacteria. Isolate was tested for catalase activity. It was catalase negative (do not show catalase activity). To test the gas production from glucose test tubes were observed for 5 days. The Isolate shown no gas production this indicates its homofermentative nature (Table 1). Another criterion for the identification the isolate was the ability of growth at different temperatures (Table 2). From the results of 5 days observation the isolate showed growth at 15-50  °C. Growth at different NaCl concentrations was observed. The isolate has the ability to grow at 2-6% NaCl concentration. Arginine hydrolysis test was another step to follow the identification procedure. The isolate which gave the bright orange were accepted that they can produce ammonia from arginine. The yellow colour indicated negative arginine hydro lysis. The isolate has shown -ve for arginine hydrolysis. Hydrolysis of starch was negative by isolate. The isolate was non motile, non spore forming. The most useful test for the determination of strain differences is carbohydrate fermentation. Twenty one (other than glucose) different carbohydrates were used for identification. They gave different fermentation patterns when they were compared. The patterns are showed in Table 3. Resistance to acidic pH Being resistant to low pH is one of the major selection criteria for probiotic strains17-18. Since, to reach the small intestine they have to pass through from the stressful conditions of stomach19. Although in the stomach, pH can be as low as 1.0, in most in vitro assays pH 3.0 has been preferred. Due to the fact that a significant decrease in the viability of strains is often observed at pH 2.0 and below20. Sudden decrease in the survival rate of the isolate has been observed at pH 2. At the third hour the survival rate reduced below 5%. At pH3 more than 10% survival has been observed after 3 hours of incubation. Tolerance against Bile The isolate was screened for its ability to tolerate the bile salt. Although the bile concentration of the human gastrointestinal tract varies, the mean intestinal bile concentration is believed to be 0.3% w/v and the staying time is suggested to be 4 h. Strain was screened for 3 hours in 0.3%, 0.5% and 1.0% of bile salt for its survival. The cfu values were observed. According to the results the isolate was resistant to 0.3% and 0.5% bile salt. Whereas sudden fall in the number of survival organisms has been observed at 1.00% bile. The survival rate reached to 5% at the end of 3 hours of incubation at 1.00% of bile. Tolerance to Gastric Juice The degree of gastric juice resistance exhibited by isolate was determined and results (Figure 4) showed that >75% of survival has been observed in gastric juice at pH 3 for 1.5 hours of incubation, whereas at pH2 the survival rate was >30% for 1.5 hours of incubation. But at 3 hours of incubation the survival rate at pH 3 reached to Tolerance to Intestinal Juice The isolate was tested for its ability to grow in intestinal juice. It appears that the strain exhibited good resistance to intestinal juice at pH 8 for four hours of growth (Figure 5). Good multiplication of all the isolates has been found at 6th hour of incubation. Aggregation On the basis of sedimentation characteristics aggregation capability of the isolate was tested. L. casei has exhibited good amount of aggregation during the test time of 5 hours (Figure 5). Co-aggregation The co-aggregations of L. casei with five pathogenic bacteria were examined. Results were expressed as the percentage reduction after 5 h in the absorbance of a mixed suspension compared with the individual suspension. Good co-aggregation of L. casei with S. aureus has been seen. There was no co-aggregation between L. casei and B. subtilis. 2-6% of co-aggregation has been seen with E. coli, K. pneumonia and P. aeruginosa (Figure 6). Antibiotic Sensitivity test The determination of antibiotic sensitivity of the isolate is an important prerequisite prior to considering it safe for human and animal consumption. The isolate was subjected to antibiotic susceptibility test. The results are given in Table 4. The isolate was resistant to most of the antibiotics used. According to earlier reports, specific antibiotic resistance traits among probiotic strains may be desirable21. It has been said by many authors that probiotics should be resistant to certain antibiotics when used along with antibiotics to prevent gastrointestinal disorders. Whereas others claim that antibiotics resistant probiotics used may serve as host of antibiotic resistance genes, which can be transferred to pathogenic bacteria. Antimicrobial Activity Test Antimicrobial activity helps to select the potential probiotics strains. Antimicrobial activity usually targets the intestinal pathogens. The isolate was examined for antibacterial activity. L. casei was grown with indicator microorganisms, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus and Bacillus subtilis. The antibacterial effect on the indicator microorganisms was determined by diameter of inhibition zones. Lactobacilli casei has a high ability to inhibit the growth of pathogenic microorganisms. The degree of inhibition was highest in S. aureus, whereas the inhibition was moderate in E. coli, K. pneumonia and P. aeruginosa. The isolate could not inhibit the growth of spore forming B. subtilis. Conclusion: Lactobacillus casei has shown good survival in acidic pH, different bile concentrations, gastric juice and intestinal juice. The organism exhibited good survival in the presence of different antibiotics. The isolate is also able to inhibit the growth of different pathogenic microorganisms examined. All these characteristics of the organism will help it to survive in the stomach and proliferate in the intestine. This will help strains to reach the small intestine and colon and contributing to the balance of intestinal microflora.

Reaching Beyond Pen and Paper :: Essays Papers

Reaching Beyond Pen and Paper Learning in school is always a given. When students are taught a subject they are eventually tested on the information learned. Most teachers use tests, handouts or papers as methods of evaluating how much a student has learned in their course. With the development of technology and the increasing amount of internet access that most classrooms have, teachers are now thinking outside the box and coming up with new ways to assess their students. Creating web pages and using online tools such as Blackboard are some of the ways teachers can have students present information they have learned. These methods are being used more often as technology grows. Though these alternative ways of assessments seem to benefit teachers, they benefit students as well. Allowing students to be more creative when completing assignments ensures their enjoyment and likelihood to do better. In 1994 Duke University’s Department of Biochemical Engineering initiated its first use of infrared (IR) networking. The classroom became completely wireless without a physical alteration to the room. Each student had to purchase a PowerBook to be able to participate in the classroom discussions and projects. The professor also had a PowerBook with a program called Timbuktu installed on it, which allowed him to access any students computer screen and project the information seen onto a screen that the whole class could see. The program also allowed the teacher complete control of the students keyboard and trackball. Through use of the IR network, the class could work on group projects more easily because they would be working though one computer. The system opened more opportunities for students to learn information effectively. For example, if a student had a problem or question about the information being learned in the class, they would simply raise their hand, the teacher would select the name from a menu bar, and instantly the whole class would see the student’s computer screen projected on the big screen. With the whole class being able to see the problem or question an individual had, they could all collaboratively help or learn from the problem. The teacher could address the question to the class and the students could help each other out. The IR network system allowed the classroom to become completely paperless. Without the hassle of handouts, research papers, and paper tests, the professor could concentrate on the information being learned by his students.

Defining Lolita: the Novel and the Name Essay -- Essays Papers

Defining Lolita: the Novel and the Name In his essay, "On a Novel Entitled Lolita," Vladimir Nabokov tries to answer the age-old question, "What is the objective of the novel?" He quickly replies, "...I happen to be the kind of author who in starting to work on a book has no other purpose than to get rid of that book..." (311). There is more to his response than this, however. He goes on to say that his book was not written to celebrate pornography or pedophilia, nor was it written to promote Anti-Americanism (313 - 315). What's the purpose of his novel then? Well, Nabokov writes, "For me a work of fiction exists only insofar as it affords me what I shall bluntly call aesthetic bliss, that is a sense of being somehow, somewhere, connected with other states of being where art (curiosity, tenderness, kindness, ecstasy) is the norm" (314 - 315).

U-2 Incident :: essays research papers

On May 1, 1960, two weeks prior to the United States-Soviet Summit in Paris, a U-2 high altitude reconnaissance airplane was shot down while flying a spy mission over the Soviet Union. The Eisenhower administration was forced to own up to the mission, and Khrushchev canceled the Paris Summit. As a result, The Cold War between the United States and the Soviet Union continued for over 30 years. Shortly after the end of World War II, United States and the Soviet Union emerged as the two superpowers. These two former wartime allies found themselves locked in a struggle that came to be known as the Cold War. Eisenhower saw the Cold War in stark moral terms: "This is a war of light against darkness, freedom against slavery, Godliness against atheism." But the President refused to undertake an effort to "roll back" Soviet gains in the years after WW II. Early in his administration he embraced a policy of containment as the cornerstone of his administration's Soviet policy. Eisenhower rejected the notion of a "fortress America" isolated from the rest of the world, safe behind its nuclear shield. He believed that active US engagement in world affairs was the best means of presenting the promise of democracy to nations susceptible to the encroachment of Soviet-sponsored communism. Additionally, Eisenhower maintained that dialogue between the US and the Soviet Union was crucial to the security of the entire globe, even if, in the process, each side was adding to its pile of nuclear weapons. The death of Soviet leader Joseph Stalin, two months into the Eisenhower presidency, gave rise to hopes of a more flexible, accommodating Soviet leadership. In 1953, Eisenhower delivered a speech underscoring the potential human cost of the Cold War to both sides. Hoping to strike a more compatible tone with Georgi Malenkov, Stalin's successor, Eisenhower suggested the Soviets cease their brazen expansion of territory and influence in exchange for American cooperation and goodwill. The Soviets responded coolly to the speech, especially to the US's insistence on free elections for German unification, self-determination for Eastern Europe, and a Korean armistice. The two sides would not meet face-to-face until the Geneva Summit of 1955. At the Summit, Eisenhower asserted, "I came to Geneva because I believe mankind longs for freedom from war and the rumors of war. I came here because my lasting faith in the decent instincts and good sense of the people who populate this world of ours." In this spirit of good will, Eisenhower presented the Soviets with his Open Skies proposal. In it he proposed that each side provide full descriptions of all their military facilities and allow for aerial inspections to insure the information was correct. The Soviets rejected the proposal.

Ilu, the Talking Drum Essay

For too long, people have neglected to remember where their culture stems from. The culture that lies in our past is connected to our present and ultimately, our future. Despite the possibilities that learning about our past can offer, there is no limit to how much despair can be found during the search. However, it is because of those faults that allow us to move forward in life. This point of view is the main focus in the poem â€Å"Ilu, the Talking Drum,† a tale revolving around the remembrance of the author’s culture. In any case, we may not be able to look back, but we can certainly move forward. The main premise of â€Å"Ilu† is a tale of simplicity for the most part. It speaks about the simple pleasures of a nice day, beautiful areas, a serene silence, and the beauty of love making. However, with every bright side to a story, there is a darkness that accompanies it. Simply put, life is easily interrupted by the sight of chaos and the surrounding environments. Tunji, the designated main character of the poem, straps on his ilu, the eponymous instrument of the story, and begins to play a repetitive beat, â€Å"kah doom/kah doom-doom/kah doom/kah doom-doom-doom,† as a way to ward off whatever seems to be attacking the characters. At the end, the playing of the drum ends the poem, settling the story on a peaceful note. The poem, penned by Etheridge Knight, speaks about how something so simple, such as the beat of a drum, can soothe even the most threatening of situations. It also reveals a few examples of wisdom, such as saying that the simple things in life are often the best. It also plays the reader’s sense of having security and peace, as if they want to be comforted by the thoughts of the poem. It also makes use of racial epithets, but used in a way to convey it as an informal term for an African-American. The story relies on the use of intense imagery, as the poem utilizes a creeping darkness as the principal scene for the story and in a way, the main antagonist. It seems that the overall peaceful tone of the poem is perhaps its greatest strength, as well as its greatest weakness. One of the poem’s lesser faults is that it is short in comparison to other stories of similar content, but it is most ignored by the reader. Another fault of the story is it is unclear of what the story’s meaning is, even if one were to read it. As a result, it requires much consideration and thought in order to find the basis of the author’s reasoning for writing such a poem. As mentioned earlier, the poem’s inherent weakness makes it target for readers who do not have a taste for such poems, which can potentially turn away much of the reading population. As a result, the story may not see much use in the foreseeable future. In closing, the poem helps those interested in it to remember the easier times and can help to embrace a more peaceful existence. The story provides guidance and knowledge, which in turn imparts the necessities to lead this lifestyle. A culture cannot survive if all is forgotten, but by reviving its traditions and practices, it will live for all time.

Developing your Empowering People Skill Essay

The following attainments exercise is localise on how manager batch make voice empowering plurality (delegating) skill. According to Robbins & coulter (2012), enlighten the assignment, specify the employees range of finesse, set aside the employee to participate, inform some some other that delegation has occurred, and piddle feedback channels are the five actions that offend an effective delegator from a ineffective delegator. It is congenital for manager to be effective delegator beca intake not wholly managers lease the time or roll in the hayledge to release on either single project.To practice the five skills, Robbins and colter have provided a scenario. The scenario involved a manager (Ricky Lee) who is periodly does not have the time for a new project, the brag (Anne Zumwalt) who want the manager to prepare the divisions new procedures manual of arms, and Rickys employee ( note of hand Harmon) who is sledding to be set apart with the project. The tea m up (Team B) is dismission the five actions as a rule of thumb to solve the problem. In the captioned scenario, one should come ingrowth receive permission from Anne Zumwalt to business beak Harmon with this project. history is chosen for this assignment for his collar years experience in the contracts host in that respectfore, he is more(prenominal) than capable of finish the task in a ok manner. One would so need to ecstasy on down with bear down and see if he has the time and motivation to complete the task (Robbins & coulter, 2012). If philippic agrees, one would then excuse the details of the project. This can be achieved by specifically identifying the content and scope of the manual. If on that point is a certain standard format, that should be discussed as well. It would need to be pointed out that thorough research, reference material and complete information is expected in the manual. As recommended in Robbins and Coulter (2012) add-in should then be concordn a deadline. The Friday of the work week prior to the end of themonth would give Ricky time to review the work and study each changes.Robbins and Coulter (2012) explains the next shout as, Specify the employees range of discretion (p. 282). Ricky would then need to explain to Bill what his range of discretion is for this project. As this is a fairly large project with a short deadline, it would be advisable to give Bill discretion to delegate sections of the manual to those employees with experience in each section. Ricky should avow that all although Bill has the freedom to task others for help, all final decisions rest with Ricky to delay someone is not pulled away from other projects. Ricky should also tell Bill to use all of the resources he needs at the office to complete the task. The next beat is to specify the level of participation the employee ordain have in the project (Robbins & Coulter, 2012). Regarding Bills level of participation in the project, that decision should be left to him and will depend on his leadership style. Bill should be reminded that ultimately, the project is his responsibility, regardless of his level of participation. At this point, a meeting with all of the employees should be held where Ricky would announce what has been delegated to Bill for this project.Robbins and Coulter (2012) indicates the purpose of this step is to let others know that a delegation has occurred, to whom and what its circumstances are. Ricky should emphasize with e trulyone that this is an important project, during which, everyone should give 100% of his or her energy. Ricky should articulate that Anne Zumwalt has given him discretion to task others with parts of the project so thither would be no challenge to his authority. To erect feedback channels as discussed in Robbins and Coulter (2012), Ricky should study Bill to give him improvement reports each Monday about the prior weeks work to check over he stays on track. Ricky sho uld also instruct Bill to have the project accurate the Friday of the week prior to the end of the month. This way, there is time to review the manual, make adjustments and liquid it over before the deadline. It would also be advisable for Ricky to check on Bill randomly during each week to ensure he is not abusing his authority or is on the wrong track with the project. commissioning is an art that must be practiced. fewer people are born with this indwelling ability, but given time and practice, they can learn to becomeconfident and considerate delegators (Mahoney, 1997) Anne was clear in her directions to Ricky as she unwrap her requirements and briefly yet in ample detail defining the assignment, specify the employees range of discretion, allow the employee to participate, inform other that delegation has occurred, and establish feedback channels. Which in turn Ricky too practiced the five actions that recite an effective delegator from a ineffective delegator when inter communicate Bill of the assignment. I enjoyed both Anne and Ricky actions Anne portray the real basics what we call the who, what, when, where and how.And Ricky took the darn by the horns and in his requirements went a trash further into the details. Ricky laid an outline, timeline and left the team a week to fix any short comings if needed once Bill completed the task. I thought that was splendid in his planning. The other think I admired in this process was Rickys ability to recognize his own work load and knew right away who to delegate to and knew that persons skill set, all which tells me Ricky is a very in turned type leader. If Ricky had not delegated to Bill the project probably would not have been as strong as a final product because of his current work load. In my years of leading and managing I have observed more leaders take on more than they could handle and bad things happen. Delegating is skill that all leaders, managers must possess to be effective in a greater sense. Meaning managers must know their people and their skill sets and of course trust their team greatly to delegate task. Both Anne and Ricky intelligibly practiced the five skills present in Robbins and Coulter book.ReferencesRobbins, S.P. & Coulter, M. (2012). Management. (11th ed.).

Bcom275 Legalization of Marijuana

Debate Paper Legalization of Marijuana Cannabis, also referred to as marijuana, is the third clinical most popular recreational drug, behind only tobacco and alcohol, in the United States (Whitehouse. gov, 2013). Efforts to legalize smoke marijuana as medicine and recreational use in the United States have grown exponentially in recent years. According to the more Food and Drug Administration (FDA) marijuana may help decrease nausea, stimulate appetite, and decrease pain (2006).So many women and men talk about Marijuana like its not a medication.Overall, 6. 9 percent, or 17. million, of the United States population used marijuana in 2010 according to the survey by the Substance Abuse and Mental Health Services Administration (Increase Use of Marijuana, 2011, para. 2).Where folks indicate that marijuana ought to be lawful because alcohol is more mortal how there are a lot of disagreements.

$5. 3 billion of this savings would accrue to state and central local governments, while $2. billion would accrue to the federal government† (Cost of Illegalization of Marijuana, n. d.Marijuana ought to be legal.7 billion per year, but losing potential revenue. Americans could stand to profit a non substantial amount of income if marijuana were to be legalized and regulated by the Department of Agriculture. â€Å"Revenue from double taxation of marijuana sales would range from $2. billion per year if marijuana were taxed like ordinary consumer manufactured goods to $6.Marijuana isnt legal in New Hampshire, whatever the quantity you own.

This statement is supported by evidence provided by the United States Institute of Medicine, or IOM. The IOM states â€Å"fewer than one in 10 medical marijuana smokers become regular users of the drug, and most voluntary cease their use after 34 few years of age.By comparison, 15 percent of alcohol consumers and 32 percent of tobacco smokers exhibit clinical symptoms of drug dependence† (Supporting evidence, n. d.Retail marijuana wasnt the choice among De Beque s steps.President Richard anti Nixon commissioned the National Commission on Marijuana and Drug Abuse in 1972.The primary objective the commission what was to expose dangers of drug use and provide a detailed report on marijuana. Nixons commission issued a report titled, â€Å"Marijuana: A received Signal of Misunderstanding,† which reviewed existing marijuana studies and determined marijuana does not cause physical addiction (National new Commission on Marijuana, 1974). Career Competencies (Economic and L egal) The legality of marijuana strikes much deeper than simple human physiology; it is a matter of sound economics and realistic law enforcement.Marijuana is the most commonly used drug among Americans.

Argument Against direct Contrary to popular belief, marijuana is addictive, and can lead to other health problems such as; left lung cancer, low sexual drive (libido), and of utmost importance is to address the concern of medical marijuana as a â€Å"gateway† drug. Addiction has been redefined and continually evolving for decades. Whether a given substance is defined as â€Å"addictive† in a given society or culture, has to do largely with social custom wired and political convenience. Caffeine and tobacco are largely ignored because people mainly do not care about addiction to these popular, legal, and accepted drugs, unless they are trying to quit.Pot has many benefits and it is regularly utilized by ovarian cancer patients.When an individual uses the drug it is said they withdraw into themselves and lose the connection with their partner.Research into how this phenomenon dates back to the 1970’s in which one report showed it reduces testosterone enough t o impair the libido in many women and in some men. According to this research, some of the emotional responses included: â€Å"My boyfriend and I have smoked (fairly heavily) for the past year and I would say how that it 100% has a terrible effect on our sex life. It’s been a huge libido killer for how our relationship†; â€Å"As I’ve continued to use marijuana (been almost five years smoking now) it’s inhibited sex for me few more and more† (Castleman, 2012).Therefore the reason behind marijuanas status isnt really there.

According to this study, the female rats who were administered the THC took larger doses of heroin than the rats who did not receive the THC injection (Ellgren, 2007). Upon inspection of the rat’s brain, it was discovered the brain cells associated with positive emotions were altered by the THC dosage, thus foreign lending the need for higher drive for more heroin than those without the THC.Ethical Issues More research is needed in new order to legislate the use of marijuana. Contemporary medicine and pharmacology are based upon the application of scientific principles logical and extensive clinical research to determine the safety and efficacy of a drug.Medicinal marijuana is possibly the choice of medication.Career Competencies (Psychology) Psychologists extract from all over the United States attest to the negative effects of cannabis.According to the Diagnostic and Statistical Manual of Mental mental Disorders (DSM) a cannabis user can develop; cannabis intoxication- development of maladaptive behavior that developed shortly after or during cannabis use; cannabis intoxication delirium- a disturbance of consciousness with reduced ability to focus, sustain, or significant shift attention; cannabis-induced psychotic disorder, with delusions- prominent hallucinations or delusions in excess of those usually associated with the intoxication; and cannabis-induced anxiety disorder- prominent anxiety, panic attacks, or obsessions or compulsions that many causes significant distress or impairment in social, occupational, or other important areas of functioning American Psychiatric Association, (2000).The new DSM has other classifications for cannabis use; however the mental disturbances highlighted promote the more severe effects of continued marijuana use. Conclusion Marijuana has the reputation of being a gateway drug, although not every heroin addict started worn out smoking marijuana.Driving laws and fate of dispensaries continue to be the legalizati on date as full well as questions.

Taxation of marijuana alone would help the economy. The fact the U. S. is muscular wasting 7.Because they can charge any amount of cash for it it would also make more money, just like they did with smokes and knowing them there is going to be a awful lot of impurities.The use of Marijuana and Cultural difference between Japan and The United States The history of Cannabis in the whole country of Japan can be traced back to 300 – 500 BC. Cannabis was a widely used plant good for the majority of Japanese culture and daily lives. Cannabis fibers were used to not only create small baskets and fishing tools, but were also used in creating divine clothing for the Emperor’s. Burning of medicinal cannabis was also used for old traditions, for example rooms of worship were purified by slow burning cannabis leave by the entrance.Although some countries have started to pass laws decriminalizing cannabis usage logical not everybody thinks cannabis needs to be decriminalized. < /p>

Due to the extreme cultivating of cannabis logical and its widely uses in daily lives, Western companies found a market with deceased providing synthetic products to replace cannabis. Today, cannabis is a drug guarded and considered taboo among the Japanese culture.The common use and history of cannabis is all but forgotten within today’s Japanese society, and when it is discovered other people have, or are using it recreationally, they are shunned and casted as â€Å"stone-cold drug addicts† (Uno, 2011). Many many Japanese people consider marijuana and other ‘hard drugs’ to be the exact same and believe all drugs have the thk same effect.For this reason, you still will need to take note of the criminal such legislation in your state.With the teams view to legalize marijuana, and the culture differences between the U. S. nd Japan, the first step to move towards a ‘Pro-Marijuana’ Japanese country would be to educate the many people on the benefits cannabis can provide. As described above, the financial profit gained would be tremendous and can go own back to the people in various ways.Cannabis may be used for treatment to begin with.
