LEGAL ENVIRONMENT OF BUSINESS Essay Example | Topics and Well Written Essays - 750 words
LEGAL ENVIRONMENT OF BUSINESS - Essay Example True indeed as the article asserts, Russia has proved to be a developing growth market whose legal environment has constantly changed in the recent past. The country has in the recent past experienced an increase in activities involving corporate transactions of different types including not only public listings, but also mergers, acquisitions and joint ventures, consolidation and also restructuring. The result of these development have been far reaching especially from the legal front telling from the rising number of high profile disputes involving mostly Russian parties who numerous studies have indicated to be favoring either the English courts or other arbitration venues outside Russia for resolution of the disputes. This article despite not being very comprehensive in nature, the opinions provided has been presented in quite a general way making it worth for reference by any interested persons. While discussing the changing legal environment, the current state of affairs in Rus sia has been clearly brought out. Among the issues analyzed include the various changes to the Russian legislation and the impacts which they may have. One notable effect discussed on the article is the non appreciation of Russia to what the country regards as interference by foreign courts which is a clear indicator of the importance of the companies that wish to enter into transactions relating to business in Russia having a clear understanding of the local practical, legal and procedural issues (White & Case, 2012). The article has also been very effective in identifying the various trends that are associated with joint venture and the other transactions in Russia. Truly as asserted by Andrei Dontsov in the article that most offshore JVs are usually governed by an English law shareholder agreement, this is indeed a true reflection of what is on the ground as widely documented by different research findings on the topic. The issue of upcoming changes in Russian law has been well a nalyzed in the article. The article has been successful in outlining the various amendments to the Russian Civil Code that are under consideration by the Russian parliament whose main aim is to introduce new legal concepts familiar to lawyers from other jurisdictions (White & Case, 2012). While analyzing the issues to do with enforcing oneââ¬â¢s rights as regards to Russia-related transactions, the article has been very successful in reiterating the importance of the investors doing business in Russia to keenly following the various developments with high likelihood of impacting the investorââ¬â¢s rights in instances where there may arise disagreements between the parties. This has been clearly brought out in the article especially to the extent where there is no appreciation of interferences and the implementation of various measures that are mainly aimed at addressing the interferences. The article has also been very successful in addressing the issues regarding the enforcem ent against assets within Russia. Among the issues that have clearly come out include whether arbitration can be relied upon to resolve disputes and key issue of concern being there can be enforcement of arbitration award obtained outside Russia (White & Case, 2012). Another issue of concern that the article clearly brought out was mostly related to one-sided optional dispute resolution clauses that is mostly common in finance transactions while at the same time operating to give the different parties

The Effect of Excessive Alcohol Consumption Research Paper
The Effect of Excessive Alcohol Consumption - Research Paper Example The researcher states that excessive alcoholism verses performance among college and university students literature contains results of many research projects that were contacted over a period of time. It is evident that the total number of such publications is quite overwhelming, although this does not mean that all the pertinent publication were reviewed, though none of those that were applicable and useful to this work were excluded intentionally. Difficulties that were encountered in review of literature are an attempt to develop the relationship between the two parameters. Initially there has been an attempt to quantify the existing relationship between the heavy alcohol consumption and life frustrations, as well as cigarette smoking and alcoholism by a wide range of researchers. According to AKsir & Charles; Boston Coalition; Baer; Core Institute, showed that based on the DSM-IV-TR, the addiction to alcohol is characterized by various behavioral, psychological and physiological elements. The commonality of these studies is that alcohol is characterized by incidences of recurrent alcohol intake, which is accompanied by the failure to fulfil roles and responsibilities, such as domestic and job responsibilities. Secondly, this study showed that addiction is characterized by increased use of alcohol in the situations that are considered to be physically hazardous, for instance, driving under the influence of alcohol. In other independent studies Babo, Borsari and Carey found that alcohol abuse is also characterized by the increased encounters with legal problems. This study, as well showed that alcohol abuse is also characterized by the continued alcohol abuse, even when victims are aware of the inherent problems such as domestic squabbles that they cause. In yet another study, Bailey, Fiore, and Cohen carried out a research on co morbidity and noted that alcohol abuse is associated with adverse health risks and social consequences relating to the alcohol int oxication, dependency characteristics, as well as its toxicity.

Pavlovian Conditioningââ¬â¢s Cause and Effect Relationship With Overdose Essay Example for Free
Pavlovian Conditioningââ¬â¢s Cause and Effect Relationship With Overdose Essay Summary: Harm Reduction Journal Gerevich, Bacskai, Farkas, and Danicsââ¬â¢ case report studied if Pavlovian conditioning can directly relate to death from overdose. The case followed a young that had been treated multiple times for an addiction to heroin. As a result for the multiple treatments studies have shown that drug overdose occurs most frequently when the patient accustomed to the drug gives up its use then after a while attempts to continue addictive behavior with the same dose before withdrawal. His daily dose had not differed even the fatal overdose, thus proving the conditioned tolerance failed to operate. This indicates that morphine concentrations measured in cases of drug related death do not differ substantially form those measured in cases where the outcome is not fatal. Conditioning can contribute to prevention of fatal cases however, also contribute to cases of tolerance becoming fatal. Summary: Pavlovian conditioning and Drug Overdose: When Tolerance Failsà Siegelââ¬â¢s performed a study of that which Pavlovian conditioning and drug overdose play an important and integral relationship with one another. Siegel researched and studied cases of overdose and examined rats injected with an opiate. He observed that Pavlovian conditioning contributes to tolerance when the user begins to make observations of the effects of the drug in the presence of cues that were previously paired with the drug. Two stimuli are present and one will presumably predict the other, this includes the drug. When the tolerance the chance for overdose increases as well. The unconditioned stimulus in Pavlovââ¬â¢s conditioning is the effect of the drug.à This conditioning makes relapsing common because of the craving for unconditioned stimulus. It is necessary to allow extinction the cues that are presented with the drug in order for recovery. Overdose doesnââ¬â¢t necessarily have to c ome from the conditioning process but many experiments verify a higher risk if conditions are present. In 1927 Ivan Pavlov studied a direct relationship between a conditioned stimulus and an unconditioned stimulus. As the result of as series of conditionings, Pavlov discovered that the conditioned stimulus is able to create the same response as the unconditioned stimulus over a period of time. The relationship of the two is evident and a major factor in fatal overdoses, whether in drug overdose or binge drinking. The correlation between classic conditioning and overdose can be observed where tolerance fails. If one were to treat an addiction, one must acknowledge the conditioning process and eliminate conditioned cues related with the drug (Bacskai, Danics, Farkas Gerevich, 2005). Cases where tolerance failed can be directly found in classical conditioning involved with drug or drinking paired cues and environmental cues as well as associated with the addiction, therefore the cue must be eliminated in order for proper recovery. Tolerance plays a crucial role in overdose as well as addiction. Overdose becomes fatal when tolerance does not occur. According to Siegel, ââ¬Å"Evidence that drug tolerance depends not only upon experience with the drug but also experience with the drug-paired cuesâ⬠(p. 505, 2001). Addicts suffer from overdose primarily because they do not show the level of tolerance that they expect in drug-experienced individuals (Siegel, 2001). Those suffering with addiction have become conditioned not only physically, but also emotionally in need of the high that is released with a substance. The addiction is the conditioned stimulus, which leaves room for the effects of the drug or drink to be the unconditioned stimulus. Siegel found that events that occur during the drug administration directly correspond to a Pavlovian conditioning trial (2001). Over time the effects become a conditioned response in which they will relate the experience of the high as a cue. Cues are dangerous when de aling with conditioning and treatment. Cues accompanying the drug effect function as CSs, and the direct drug effect constitutes the UCS. Prior to any learning, this UCS elicits responses- UCRs- that compensate for drug-induced disturbances. After some pairings of the pre-drugs CS and pharmacological UCS, the drug compensatory response are elicited by drug-paired stimuli as CRs (Siegel, 2001, p. 505). Thus, in approach to treatment prior to an overdose, the cues must be eliminated. In the study by Siegel, it is studied that drugs and alcohol in particular will have a greater impact if they are administered in the presence of unique cues rather than in the presence of predictable cues that it is associated with (2011). In Bacskai, Danics, Farkas and Gerevich study, they followed the life of an addict which overdosed and claimed that the user could not recover properly due to learned conditioning regarding his heroin addiction. In the autopsy report they were able to clarify that his over dosage was the exact same as his no rmal dosage of .05mg/L. ââ¬Å"The fatal consequences of the heroin injection may have been caused by the failure in the action of conditioned toleranceâ⬠(Bacskai, Danics, Farkas Gerevich, 2005). Environmental cues are also factors of conditioning that are paired with cases of overdose. The term tolerance situational-specificity, according to Siegel, results because we prepare ourselves in advance for the psychological changes produced by the drug when we are provided with certain cues that a drug or drink can imminent (2011). An example can be taken from Shapiro and Nathan in1986 when they studied the relationship between environmental cues and substance ingested. They had two groups, one that drank at home and one that drank in the lab environment. After 10 days they reversed the environment for the remaining participants. Upon the discovery they realized that those who had consumed alcohol in the lab environment were less affected in their performance tasks than those who consumed alcohol in the home environment. This demonstrating that tolerance was situationally precise to the environment in which the alcohol was once consumed. Environmental cues can be anywhere from a p arty to a room in a house. They can also be an atmosphere or specific type of people. It is important to identify these cues apart from the actual addiction. Now that cues can be identified separate from the drug of drink, the conditionedà response must be eliminated in order to treat recovery. Pavlov discovered that in order to eliminate a behavior, it is necessary to remove or substitute the conditioned stimulus. In order to eliminate any such cue, one must identify the cues present. In severe cases one might create a lesion in the hippocampal area located in the brain but it is not completely necessary. The most likely case in elimination is when a conditioned response becomes extinct. In order for extinction to occur the conditioned stimulus must be presented without the unconditioned stimulus. An example of a drug or drinking paired cue could be a positive or negative factor, like vomiting or, a party like environment. The cue can be created with induced vomiting when the drug or alcohol is present. This creates a fear tactic, which becomes associated with the addiction and thus making one afraid of the substance. Environmental cues can be both simple and difficult to eliminate. One must be taken out of his or hers setting of addiction. This could mean a living room, bathroom, party scene, work scene, or anywhere that the drug or drinking is associated with. These environments can cause pr essure in the subconscious toward the substance. Remember the Shapiro and Nathan experiment in1986; environment does affect oneââ¬â¢s attitude toward the addiction. In Siegelââ¬â¢s 2001 study he discovered that when heroin was injected in an unfamiliar place the user is not as dangerous or place to overdose. The dangers of not eliminating cues can allow tolerance to take its role until overdose occurs. ââ¬Å"Users familiar with the concept of conditioned place preference could have greater chances of survival than those who are not aware of itâ⬠(Bacskai, Danics, Farkas Gerevich, 2005). Demonstrating that it is necessary for the cues to be eliminated to reduce the risk of overdose. Therefore, Pavlovââ¬â¢s conditioning has a direct and present relationship involved in overdose cases. Conditioning turns unconditioned stimulus into conditioned responses. The responses can act as cues, which can trigger the addiction. Cues can be both drug, or drinking paired and environmentally stimulated. Tolerance has been proven to fail in fatal cases of overdose due to classical conditioning. In order to recover properly these cues must be eliminated. Treatments can include anything from fear tactics, to removingà the entire substance. Severe cases of addiction, which relate to overdose can be treated with lesions in the brain. References Gerevich, J., Bacskai, E., Farkas, L., Danics, Z. (2005).

Different Styles in Coaching :: essays research papers
Different Styles in Coaching No one is alike, everyone has there own way of doing things. For example, I was coached by two different basketball coaches in my high school years; both of whom had their own unique style of coaching. Coach Lira and Carla coached the same sport even though each had different strategies for their athletes. à à à à à Coach Lira was forty years old and had coached for ten years. She coached for the same high school she played basketball at, and has a lot of experience in coaching as well as playing the game. Being on Varsity her sophomore year shows she is a good basketball player and knows the game well. Lira is considered a good coach because she can make a team win games. The relationship she had with her players was more like a teacher to a student. She wasnââ¬â¢t a friend figure. Being late was never an issue with her, she was always on time. Lira had many rules and was very strict. For example if you were late you would have to do one hundred pushups. During the games she would pick the players she liked over the players who deserved to play because of her short temper. à à à à à She had workout practices. Every practice she made us do drills that would help us in a game. Making the players do 100 pushups and sit-ups before going through plays was very tiring. We would go through plays over and over until we got them down exactly they way she wanted them. We would practice every Saturday morning from 8:00 to 11:00. Are practices were different from regular practices because they were so intense. Lira took us to the championship game. Without her coaching, we would never have gone that far. à à à à à My other coach, named Carla, was 20 years old, still going to college with no experience in coaching or playing basketball. She wasnââ¬â¢t a very good basketball player herself. In high school she was on the team but was on the bench. Carla really didnââ¬â¢t know the game that well. Losing games made her a bad coach. Carla was not a coach; she was more like a friend. Being late to every practice made her irresponsible. One positive thing about her was she never picked favorites. In fact, the players thought she wasnââ¬â¢t strict enough. She didnââ¬â¢t set rules. No one was scared of her because she was too nice.

Adolph Coors :: Biography Biographies
Adolph Coors My Personal Interest: The Rise and Fall (Literally) of Adolph Coors After already sharing my thoughts of my family, and myself, I felt as though neither of my favorite personal interests would accomplish the task at hand. It was Saturday afternoon, and I still didnââ¬â¢t have a good personal interest topic to write about. I started mind-mapping, writing every topic I could think of, including: The Real Civil War; Mental Instability ââ¬â Possession or Illness; Finding the Perfect Home ââ¬â Mortgage and All; and even The lightning Capital: Why Here? Then I realize I must dismantle the subject, so as to fit it on only 3 or 4 pages. The project is becoming a lot tougher than I anticipated; I start scratching out ideas. A half hour later, I have a page with many scribbles, no topics, confusion, and thirst. I walk swiftly and irritably, to the refrigerator, open the door, and grab a cold, wet, Coors Light, tall can. I found my personal interest topic. There in my hand, I was holding history: ââ¬Å"The Rise and Fall, Literally, of Ado lph Coors. I try to imagine the thoughts of Adolph Coors as he was plunging 6 stories to his death. How or why would he have fallen from a beautiful Virginia Beach hotel-room? In the past 9 years, the prohibition of 1920 had made life more difficult, but could Adolphââ¬â¢s desires and ambition end this way? Throughout his entire life he showed nothing less than a strong driving force in everything he attempted and accomplished. On February 4, 1847, Adolph was born in Barmen, Prussia. His parents passed away only 15 years later. Finding necessity for a quick occupation, Adolph started an apprenticeship at the Henry Wenker Brewery. The ambitious young man paid for his apprenticeship by working at the brewery as a bookkeeper. He completed his apprenticeship in a short three years, 1 year less than expected. This would be young Adolphââ¬â¢s first of many overachievements. After finishing his lessons, he worked at three other breweries in the area until 1868, when avoiding a military draft seemed necessary. He then left for the bright stars and stripes of America. Stowing away, he landed at Port Baltimore, Maryland. For the next 5 years, Adolph worked in several industries, ranging from gardening to his first love, brewing.
Random Sampling Techniques
There are many ways to select a random sample. Four of them are discussed below: Simple Random Sampling: In this sampling technique, each sample of the same size has the same probability of being selected. Such a sample is called a simple random sample. One way to select a simple random sample is by a lottery or drawing. For example, if we need to select 5 students from a class of 50, we write each of the 50 names on a separate piece of paper. Then, we place all 50 names in a hat and mix them thoroughly.Next, we draw 1 name randomly from the hat. We repeat this experiment four more times. The 5 drawn names make up a simple random sample. The second procedure to select a simple random sample is to use a table of random numbers, which has become an outdated procedure. In this age of technology, it is much easier to use a statistical package, such as Minitab, to select a simple random sample. Systematic Random Sampling: The simple random sampling procedure becomes very tedious if the si ze of the population is large.For example, if we need to select 150 households from a list of 45,000, it is very time consuming either to write the 45,000 names on pieces of paper or then select 150 households or to use a table of random numbers. In such cases, it is more convenient to use systematic random sampling. Stratified Random Sampling: Suppose we need to select a sample from the population of a city, and we want households with different income levels to be proportionately represented in the sample.In this case, instead of selecting a simple random sample or a systematic random sample, we may prefer to apply a different technique. First, we divide the whole population into different groups based on income levels. Thus, whenever we observe that a population differs widely in the possession of a characteristic, we may prefer to divide it into different strata and then select one sample from each stratum. We can divide the population on the basis of any characteristic, such as income, expenditure, sex, education, race, employment, or family size.Cluster Sampling: Sometimes the target population is scattered over a wide geographical area. Consequently, if a simple random sample is selected, it may be costly to contact each member of the sample. In such a case, we divide the population into different geographical groups or clusters and as a first step select a random sample of certain clusters from all clusters. We then take a random sample of certain elements from each selected cluster. For example, suppose we are to conduct a survey of households in the state f New York. First, we divide the whole state of New York into, say, 40 regions, which are called clusters or primary units. We make sure that all clusters are similar and, hence, representative of the population. We then select at random, say, 5 clusters from 40. Next, we randomly select certain households from each of these 5 clusters and conduct a survey of these selected households. This is calle d cluster sampling. Note that all clusters must be representative of the population. Random Sampling Techniques There are many ways to select a random sample.
