Process data shows Essay Example

Process data shows Essay A 0. 60 um film of silicon dioxide is to be etched with a buffered oxide etchant of etch rate 750 A min-1. Process data shows that the thickness may vary up to 10% and the etch rate may vary up to 15%. The maximum possible thickness of the silicon dioxide film is therefore 110% of its nominal value. Therefore, the maximum possible thickness of the silicon dioxide film can be determined through the following calculation: where zmax is the maximum possible thickness of the silicon dioxide film and znominal is the nominal thickness of the silicon dioxide film. Therefore, znominal = 0.  60 um. Any number expressed as a percentage can alternatively be expressed as a decimal. For example, 110% can be expressed as 1. 1. Using this decimal format, the above formula can be rewritten in the following manner: Substituting our previously determined value for znominal into the above formula yields: with significant figures applied Similarly, the minimum possible etch rate of the buffered oxide etchant is 85% of its nominal value. Therefore, the minimum possible etch rate of the buffered oxide etchant can be determined through the following calculation: Where rmin is the minimum possible etch rate of the buffered oxide etchant and rnominal is the minimum possible etch rate of the buffered oxide etchant. Therefore, rnominal = 750 A min-1. Using the conversion factors 1 A = 10-10 m and 1 um = 10-6 m, rnominal can be converted to um min-1 in the following manner: with significant figures applied As was demonstrated above, this percentage value can alternatively be expressed as a decimal. Therefore, 85% can be expressed as 0. 85. Using this decimal format, the above formula can be rewritten in the following manner: We will write a custom essay sample on Process data shows specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Process data shows specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Process data shows specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Substituting our previously determined value for rnominal into the above formula yields: with significant figures applied I have completed this question with the assumption that the etching process is perfect, with no overetching or underetching. This implies that the time required to complete the etching process is exactly the time required for the buffered oxide etchant to etch to the interface between the silicon dioxide layer and the substrate. I have also completed this question with the assumption that the buffered oxide etchant is a wet etchant, and that it etches isotropically. The slide entitled Isotropic Wet Etching and Feature Size in section 5 of the notes states the time required for a perfect etch using a wet etchant, with no overetching or underetching. This time is given in the following formula: where z is the thickness of the film, r is the etch rate of the etchant and ? is the time required for a perfect etch, with no overetching or underetching. The thickness of our silicon dioxide film may vary up to 10% and the etch rate of our buffered oxide etchant may vary up to 15%. Therefore, the time required to complete the etching process may also vary. From the above equation for ? , we can see that the maximum possible time required to complete the etching process occurs when z is maximized and r is minimized. Therefore, we can slightly modify the above equation for ? to represent the maximum possible time required to complete the etching process: where ? max is the maximum possible time required to complete the etching process, with no overetching or underetching. Substituting our previously determined values for zmax and rmin into the above formula yields: with significant figures applied Therefore. Max represents the maximum possible time required to complete the etching process, with no overetching or underetching. b). I have completed this question with the assumption that the buffered oxide etchant is a wet etchant, and that it etches isotropically. For an isotropic wet etching process, undercutting will occur at the top of the silicon dioxide layer. The slide entitled Isotropic Wet Etching and Feature Size in section 5 of the notes states the amount of undercutting that would occur at the top of the silicon dioxide layer for a perfect etch, with no overetching or underetching. Since the etchant is isotropic, it must etch equally in all directions. Additionally, the etchant is always in contact with the top of the silicon dioxide layer during the etching process. Therefore, it etches horizontally along the top of the silicon dioxide layer for the entire time for which the etching process occurs. Therefore, the length of the undercut that is generated at the top of the silicon dioxide layer is simply equal to the etch rate of the buffered oxide etchant multiplied by the time of the etching process. Mathematically, Where xundercut is the length of the undercut that is generated at the top of the silicon dioxide layer. I have completed question 6-1-a with the assumption that we are etching for the maximum possible time required to complete the etching process. As a result, whatever variations in film thickness or etch rate may occur, the film of silicon dioxide will be fully etched through. The maximum undercut will be generated if the buffered oxide etchant etches at its maximum possible rate. The maximum possible etch rate of the buffered oxide etchant is 115% of its nominal value. Therefore, the maximum possible etch rate of the buffered oxide etchant can be determined through the following calculation: where rmax is the maximum possible etch rate of the buffered oxide etchant and rnominal is the nominal etch rate of the buffered oxide etchant. Therefore, rnominal = 750 A min-1. Using the conversion factors 1 A = 10-10 m and 1 um = 10-6 m, rnominal can be converted to um min-1 in the following manner: with significant figures applied As was demonstrated above, this percentage value can alternatively be expressed as a decimal. Therefore, 115% can be expressed as 1. 15. Using this decimal format, the above formula can be rewritten in the following manner: Substituting our previously determined value for rnominal into the above formula yields: with significant figures applied the above equation for xundercut can be modified slightly to yield the length of the undercut that is generated at the top of the silicon dioxide layer after the maximum possible etch time and with the maximum possible etch rate. Mathematically, where xundercut_max is the length of the undercut that is generated at the top of the silicon dioxide layer after the maximum possible etch time and with the maximum possible etch rate. Substituting our previously determined values for rmax and ? max into the above equation yields: with significant figures applied The minimum undercut will be generated if the buffered oxide etchant etches at its minimum possible rate. The minimum possible etch rate of the buffered oxide etchant is 85% of its nominal value. Therefore, the minimum possible etch rate of the buffered oxide etchant can be determined through the following calculation: where rmin is the minimum possible etch rate of the buffered oxide etchant and rnominal is the nominal etch rate of the buffered oxide etchant.

Colonial America essays

Colonial America essays Colonial America was a successful establishment in less than a hundred years. The first official census of the United States was 3,900,000 in 1790. Most of the population came from a high birthrate from the settlers; while the other half of the population came from the intense immigration of slaves. While the settlers came in hope of a better life, their goals could not be reached without hard work, work that they were not accustomed to. This called for the need of slavery. Captured Native Americans were also used as slaves, but that eventually did not work anymore. With no one else working on the land, the colonists needed major help. Slavery was one of the most important reasons people moved to colonial America. Slaves were imported mostly from West Africa, and they had no choice but to do what they were told. But the slaves obviously did not work for themselves. They worked for colonists from Europe, mostly England. Colonists started to move to America in hope of living a better life. If your status was not that great in England, coming to America was a chance to improve your status. Colonists were offered land to live and work on, and there was lots of land to be distributed so living expenses would also be a lot cheaper. This gave the lower-class better opportunities for a better life. Also, if you were an indentured servant, after you serve your time, you were given land of your own and no longer worked for anyone but yourself. Another reason why so many people to moved to America was because England was overpopulated. They forced Englishmen off the land and exported them to America. But England did not export their good men; they exported poor people, and prisoners (mostly all lower classes). England felt that they needed to get people off their land because if the population continued to grow, it could lead to disasters for the country. So people came to Colonial America for various reasons, whether it be f...

Human Resource Management - Research Paper Example There are thousands of websites on the internet that specialize in advertising jobs for people. Three of the largest jobs posting websites are Monster.com, Careerbuilder.com, and CareerPath.com. These websites allow the user to search through databases that often have hundreds of thousands of jobs available throughout the nation. For instance signing up for Monster.com is free of charge for a job seeker. Corporations pay Monster.com a fee for using the space in their website to place job postings. Online recruitment is a strategy that can be used by both small and large corporations. The use of online recruitment can accelerate the process of obtaining candidates for a job posting because the firm receives the application for the job instantly via the internet. Companies gain access to a large pool of applicants by using online recruiting (Whatjobsite, 2009). The internet enables a firm recruiting online the ability to advertise a job posting during all hours of the day. Once a compa ny identifies a potential candidate through its online recruiting efforts the firm can continue the selection process using online tools such as giving assessment tests to the candidates or interviewing them using video chat platforms. The use of online recruiting offers many advantages to a company. One of the greatest advantages of online recruiting is its low cost. Advertising jobs in the written media can cost companies thousands of dollars due to the fact that firms have to pay for advertising space in several newspapers or magazines in order to reach potential candidates for the job position. Receiving applications for jobs online can help companies sort through the applications a bit faster than paper filled applications. Another advantage of online... Human Resource Management Since the turn of the 21st century the world entered into new economic age known as the broadband age. The internet is the key technological advancement that spurred economic activity during this era. One of the hottest trends in recruiting is online recruitment. The purpose of this paper is to analyze and describe online recruiting. â€Å"The internet has become one of the prominent of all worldwide recruiting efforts† (Ivancevich, 2001, pg. 195). The proliferation of the internet is one of the reasons the internet has become such a popular recruiting tool. As of June 30, 2012 there were 2.4 billion internet users worldwide (Internetworldstats, 2012). Over 34% of the global population uses the internet on a regular basis. The use of the internet for recruiting is a strategy that most companies utilize due to the fact that online recruiting is an inexpensive way to advertise job positions. Companies that have corporate websites should utilize their websites to recruit personne l. The job application process of a firm that uses online recruiting often starts by the applicants submitting a job application through the website or by sending a resume to the firm via email. Due to the large amounts of resumes multinational corporations receive each day firms should use a separate email address to receive resumes. Online recruiting is a tremendous tool that all companies should be using. In the past I have used the internet to apply for jobs. I was able to apply for jobs in my region and for job positions in different parts of the country using the internet.

ASSESSMENT This module is assessed through One Literature Review (3500 words) which you must submit electronically Submit - Essay Example The banner of ‘Islamic world’ and its homogeneity is represented by discursive practices and not by diversity of geographical boundaries, politics, history, language as well as broader contexts of material life. Various sources including new orthodoxy in government circles as well as mass media represents Islam as an ‘exceptional’ case making Muslims to be detached racialized and essentialised (Hunt, 2002). The veil is considered as an Islamist attire symbolizing loyalty to the religion and analogous to swastika used by Nazism. The argument over Muslim women’s clothing has led to emerging political battles. However, wearing the veil is considered part of the agenda of Islamic fundamentalism ( Modood, 2009 ). According to the article the veil is barbaric symbol which have been fought years past but still presents symbol of inequality and lack of freedom for women. The veil amongst other issues is considered to hide various women characteristics, virtue and status, for instance it could hide a loving mother as well as truly religious woman. There is some level of difficulty in differentiating which of the women hidden in veil represent genuine Islam. Linking the veil to Islamic fundamentalism of ‘child marriage’ and ‘murder’ represents it as a symbol of barbarism as discussed above (de Castro, 2004). This has been considered as contributing towards larger percentage of Islamophobic atmosphere which links veiling to illegal activities which in actual sense are far away from the truth. According to this article, the veil is compared to balaclava normally used by armed robber or a mugger. This is because both outfits shield identities of the wearer. In the same instance, the veil is considered as key signifier of Islam especially in ‘war against terror’ where it is constructed in the imagery of intruding violent threat. The attire has also been used in constructing public discourse which links I slamic religion to political questions on violence affecting regions such as United States and United Kingdom. The picture of veiled woman is sympathetically constructed as victim of extremism within the society. This was even used as key justification for the bombing of Afghanistan and Iraq, since the countries were considered as exercising disregard for the plight of Afghan women. Oppressive regime of Taliban equates veiling with tyranny hence considered as part of enemy’s territory. Werbner, P. (2007) ‘Veiled Interventions in Pure Space: Honor Shame and Embodied Struggles among Muslims in Britain and France’ in Theory Culture and Society, 24(2) pp. 161-186 According to the article various theoretical bases of state and law have been enacted as a recognized means of handling differences in human behavior as portrayed by religious dogmas. Basically, the kind of faith predominant in an area is as a result of strong traditional, cultural and political features as presented by occupants. However, the natural law identifies certain human objective values and demands as the basis for legal systems within regions. According to doctrine of natural law, various important components of traditional and cultural behavior are considered as having strong influence on human rights. Conversely, religion is considered as specific cultural form capable of

Operations management (see assignment requirements) Essay

Operations management (see assignment requirements) - Essay Example 2. The Range of Technologies in the Modern Retail Industry An efficient supply chain involves better inventory management and reducing the time from the procurement to the final delivery. For these purposes both supply chain strategies and supply chain technologies are integrated into supply chain management to result in an efficient network of logistics. These technologies include transportation, management and communication technologies which work hand in hand to lead to an evolution of the supply chain. Information technology and decision support system are some of the common technologies being used in today's supply chain management. IT is implemented in the supply chain for strategic planning, virtual enterprise and knowledge management. Another reason why IT is frequently used is the E-Commerce factor of businesses these days(Ngai, 2004).These technologies ensure that a sophisticated analysis of the abundant available data is made possible and the results are used to obtain a c ompetitive edge in the market(Simchi-Levi, 2003). Business redesigning and the implementation of technology in business are often considered to be complimentary with each other. Therefore the integration of technology is bound to change the face of retailing operations. IT is a design tool used for knowledge and business management to produce tangible results such as time reduction, cost reduction and an improvement in the output quality. (Michael Lewis, p. 103) These innovations in Information Technology include Radio Frequency Identification (RFID), Electronic data Interchange (EDI), Pints of sales (POS) and other Data Mining (DM) technologies. These have radically changed the way retailers do their business and brought about efficiency by reducing labour costs, improving inventory accuracy, reducing lead time and increasing the rate of order fill. Points of sales (POS) POS has been in use since the 1980's and it facilitates the sale of products by entry and access of products in stores. POS allows for automatic and dynamic updates of inventory and sales data when sales occur. Thus this system is frequently used for store transactions, refunds, cash authorizations, exchanging issues and inventory tracking. Radio Frequency Identification (RFID) RFID is a generic name for technologies which use radio waves to identify and track objects. It identifies the items by reading a tag and a considerable amount of information is transmitted by just reading of the tag by the reader. This technology can capture product information which can be up to 40 times more than the typical barcode technology. RFID works as an information facilitator which can directly help in developing and aiding decision making in the supply chain. The main features of RFID are real and automatic data capture, enhanced information quality and support for business transactions. Data Mining (DM) Data mining is a process of extracting knowledge from a large database to build predictive models for b usiness decision making. It is used to make strategic and tactical decisions such as sales forecasting, customer acquisition and retention. From the supply chain point of view, they can also be used to make operational decisions like supplier

Development of attribution theory

Development of attribution theory The Attribution Theory was developed by Fritz Heider, it looks at how people make sense of their world, and how they interpret events and relate them to their thinking and behaviour. The Attribution Theory divides the behaviour attributes into internal and external factors, internal attribution is an attribution that is made by looking at a persons characteristics, such as intelligence or personality, on the other hand external attribution is an attribution that is made when looking at factors outside the persons control, such as bad luck or peer pressure. Psychologists have found from research that people are often biased in their ways of thinking and judgment when deciding who or what is the cause of an event or action. External factors are attributed when others are successful in their goals and we are not, but internal factors are attributed when we are successful in our goals and others fail (Heider, 1958). The correspondent inference theory describes that an attribution is made when a judgement made by one person on another persons behaviour, which has been caused by a particular trait. This suggests that we believe that a persons behaviour is intentional and after identifying this we try to look for a personal characteristic which may have caused this behaviour (Manstead, Hewstone, 1996). According to the correspondent inference theory we can make a correspondent inference based on 2 major factors, the first is when we perceive that the person freely chose the behaviour, and the second is when we perceive that the person intended to do whatever he or she did. An example of correspondent inference is if we see someone beating someone else up, we will assume that they are going this deliberately, not because they are pretending and that they are a violent person by nature. An internal attribution is likely to be made if we think that the behaviour was freely chosen, intended and low in social desirability, an external attribution is more likely to be made if we believe that the behaviour was not freely chosen, unintended and socially desirable, we usually over rate internal attributions and under rate the role of external attributions. The covariation theory believes that people decide that the most likely cause of any behaviour is the factor that occurs as the time as the behaviour. The covariation theory focuses on external attributions in contrast to the correspondent inference theory which focuses on the process of making internal attributions and the factors beyond the person that may be causing the behaviour. According to the covariation theory, to make an attribution 3 pieces of information are needed. The first is consensus information, which informs us of whether other people have had a similar or different reaction when in the same situation. A situational attribution is made if there is a high consensus, which would indicate that others has a similar behavioural reaction, a person attribution is made if there is a low consensus, which would indicate that others had a different behavioural response. The second piece of information needed is distinctiveness information, which describes the situation in whi ch behaviour occurred, and determines whether or not the situation is unique or distinctive which may have caused the behaviour (Bordens Horowitz, 2002). A person attribution is made if the person acts this way in other situations as well as in this particular situation, however if the person does act differently in this situation compared to other situations then a situational attribution is made, and we assume that the behaviour was most likely caused by the situation that the person was in and not by the person themselves. The last piece of information needed is consistency information, which informs us of whether the person has acted this way before or if this is a one-time behaviour. One of the limitations of the covariation theory is that it fails to distinguish between the intentional and unintentional behaviour of a person (Hayes, 2002). Jurors often make internal and external attributions of the defendant and of the victim when declaring their verdicts within the courtroom. In one study researchers found that the jurors verdicts or suspicions of whether or not the defendant was guilty were not influenced by whether the defendant was disabled or not. Those jurors who did think that the defendant was guilty were less likely to convict the defendant if they were described as disabled rather than non-disabled. This tendency occurred because the jurors made fewer internal attributions for the disabled juveniles actions (Najdowski, Bottoms, Vargas Cummens, 2009). One case study investigated the trials in which the defendant was charged with a firearms related offence, it was found that if the accused had intended to use the firearm then they were found guilty by the jurors. This case study shows supports for the correspondent inference theory as the defendant chose and freely intended to use the firearms (Tinsley, 2001). In a film called 12 Angry Men, a young boy is put on trial for the murder of this father, the majority of jurors decide that the boy is guilty. One juror, played by Lee J. Cobb makes internal attributions of the boys behaviour based on the fact that he is from the slums, and believes that the boy must have no respect or sense of morality because of where he is from (Lumet, 1957). A criticism of the correspondent inference theory is that is does not account for fundamental attribution error, which is a term used when people intensify the importance of explanations linked to a persons personality and reduce the importance of explanations linked to the situation which occurred to explain a persons behaviour (Heffner, 2001). In the film 12 Angry Men, evidence used against the boy includes when he is heard shouting at this father Ill kill ya before leaving the house, as the film continues, jurors begin to argue among themselves and Lee J. Cobb is insulted, to which he replies Ill kill ya in anger. This is a good example of fundamental attribution error as Lee J. Cobb was angry in the situation and does not actually mean he is going to kill the other juror. In addition to this another pointed out that if the boy went back to retrieve the knife he must have been guilty and was trying to cover up the evidence, which suggests that if he did kill his father then he intended to do so. It seems that a defendants characteristics have a strong influence on jurors decision making, Dowdle, Gillen and Miller (1974) concluded that significant leniency is applied to defendants who are attributed with positive characteristics by jurors, compared to those who are attributed with negative characteristics (Decaire, 1999). When the juror is provided with previous convictions of the defendant in trial, this can provide them with extra information as well as influence their decision. In one study, researchers investigated the effects of the defendants prior record on mock jurors judgements and found highest conviction rates would occur when the defendant had a prior sentence which was the identical to the charge they were presently being prosecuted for, and lowest conviction rates if the defendant had no past convictions (Wissler Saks, 1985). This shows support for the consistency element of the covariation theory, as previous convictions of the same present charge provide jurors which an attribution that this person has behaved this way before and is repeating this behaviour despite being convicted. Padawar-Singer and Barton (1974) found that there was a 50% more chance that jurors decided the defendant was guilty if they were aware of the defendants past criminal record, compared to if they did not have this information (Brewer, 2002). In support of this, one study found that mock jurors were more likely to convict the defendant when they had evidence of a prior conviction than when they had no evidence (Greene Dodge, 1995). It may argued that jurors should make their decisions based on the evidence available and not on information about the defendants past convictions because people do change and just because a person was convicted once does not mean that this should be used against them for their entire life. However in one case study it was found that Simon Berowitz was cleared of burglary at a solicitors office without the jury knowing that he had 230 previous convictions for burglary. In this instance jurors should have been provided with the information of Berowitzs previous convictions as the consistency of his actions would have allowed jurors to make a more informed decision, but as the jurors were not provided with the defendants previous convictions they may have made a situational attribution using distinctive information, believing that Berowitz had never been charged for burglary before (Brewer, 2002). In the film 12 Angry Men, the juror played by Jack Klugman was portrayed as a man who, like the boy, was from the slums, initially he seems unsure whether the boy is guilty or not but goes along with the majority verdict because of pressure (Lumet, 1957). This is an example of situational attribution using consensus information, as described by the covariation theory, as the juror is looking at the decisions made by others and then makes his own. Not all research has found that jurors make internal or external attributions about the defendant when making decisions. In one study, a survey was performed and it was found by researchers that one of the most influential factors contributing to jury making decision was the knowledge jurors had of the law as well as the instructions and information about the case (Kakar, 2002). Other factors may also affect jurors decision making such as the ages of the jurors, in one court case, researchers found a difference in length of sentence and the amount of responsibility attributed to the parent between undergraduate mock jurors and high school mock jurors (Ackerman, McMahon Fehr, 1984). Racial leniency is also another contributing factor found in many jury studies, Sommers Ellsworth (2000) and Ugweugbu (1976) both found that the jurors decisions were influenced when the juror was of the same race as the victim or defendant. People make internal and external attributions on a day-to-day basis trying to find an explanation as to why people behave in a certain way and although many studies have found that jurors use the information of intent of the defendant, past convictions and the behaviour and verdicts of their fellow jurors to help them making a decision, there have also been other studies which show other contributing factors which should be taken into account, such the age, race, gender of the juror and the defendant as well the amount of knowledge the juror has about the law.

Voice Over Internet Protocol Essay -- essays research papers

Voice Over Internet Protocol(Voip) VOICE OVER INTERNET PROTOCOL (VoIP) INTRODUCTION: In the eyes of most, all packets are created equal. One of the most active areas of telecommunications today is in the area of Voice over Internet Protocol (VoIP). The logic behind this trend makes perfect sense. If we have invested heavily in an Internet Protocol (IP) network, why can’t we make full use of it? This is a question posed by many managers and Information Technology (IT) professionals in a wide range of businesses. Many businesses would prefer to have one network in and out of their business for reasons ranging from cost effectiveness to manageability. IP telephony offers a promise of consolidation. This will allow an enterprise to converge its traditional phone system and newer data network for greater efficiency. Arieh Dranger, president of neXTel Systems LLC says, â€Å"I don’t think it’s a question of whether we need VoIP, but when it will come together, because it represents a natural progress o f integrating data—period. The IP protocol is probably the most efficient at combining a universal communications network.† Basically, IP telephony is taking the telecom world by storm. It has evolved from a little known and used application in 1995 to an application that is poised for global adoption. But as with all technology, there is a price to be paid, and several entities vying for a piece of the pie. WHAT IS VoIP and HOW DOES IT WORK? To put it simply, VoIP means Voice over Internet Protocol. It’s a technology that allows network managers to route phone call over the network they use for data transmission. A voice travels over a corporate Intranet or the Internet instead of the public telephone system. Special gateways installed at both the sending and receiving end of a communications channel converts voice to IP packets and back again to voice. This process must take place in a time frame of less than 100 milliseconds to sustain the Quality of Service ( QoS) that users are accustomed to from the Public Switched Telephone Network (PSTN). Now let’s take a walk on the more detailed side of what VoIP is and how it works. First and foremost, VoIP is an emerging technology still in the early stages. A personal computer (PC) must capture an analog voice and convert it to a digital signal, compress the audio with a compression-decompression (codec) device and then move... ...the Internet. The players are as equally far flung, from the traditional cornerstones of the Plain Old Telephone System (POTS) to the new generation startups, to the steps of local, state, and federal governmental agencies. Such dynamism makes it difficult for IT managers to filter the flood of information and assess how VoIP might fit into their networks. Unless PSTN undergoes some massive restructuring, its long-term existence in its current form is in serious doubt. Emerging Internet technologies will be the low cost solution for managers looking for mixed traffic connectivity. Only in the end, after all the smoke has cleared will we know which business models survived the shake down in this lucrative market. Other problems are bound to arise in the arenas of technology and regulation. At this point there is significant progress to be made in the area of VoIP to achieve the quality we enjoy today with the PSTN. The only sure thing from this technology or any other that will al ways be consistent, reliable and never become outdated is that the Government WILL find a way to ensure their revenue stream†¦ after all â€Å"There’s no such thing as a free lunch.† 6 pages Word Count: 2352

Let the Punishment Fit the Crime Essay

If you can’t do the time don’t do the crime or how about let the punishment fit the crime. These two statements have been around for years. If someone commits a crime they should be punish but to what extent? Should similar crimes be dealt with the same? Such as if a person had a small amount of marijuana for personal use in a car at school, or they had an ounce of marijuana in their vehicle in a school zone. Should the law treat these incidents the same? Or should they treat these cases differently? Some people believe you should be sentence to a mandatory jail term no matter what crime you commit. They feel this will deter people from committing crimes. Others feel criminals are doing too much time for mostly none violent criminal activity which put a strain on entire communities. This debate has been brewing for years. Are mandatory minimum sentences doing more harm than good? The movement to establish mandatory minimum sentences for drug related offenses began in the early 1950†s and gained momentum in the early 1970s (Carrillo, 2000). At this time the judge had the discretion of giving the defendant a mandatory sentence or a more lenient sentence. In 1986 the law was changed were as the judge lost the power to make a choice in the length of a sentence he or she could impose on an offender. They had to follow strict sentencing guidelines which some judges was even oppose to. The main reason for the mandatory minimum sentences during the earlier stages in the game was due to the growing drug trade. This was a losing effort by law enforcement to stop the trafficking of drugs into the United States. In the eyes of many this obviously didn’t work. As time went on the drug trade became bigger and better with more sophisticated technics and more potent drugs.

Rise of the American Political Parties essays

Rise of the American Political Parties essays There have always been irrational views of our nation from the people. Some believed if you desire a strong federal government, youll need to address the key factors; ease any national problems, establish a plan to activate industrialization and infrastructure, and develop a commercial economy which would help strengthen the government and its power. These factors were believed to be the sole of the problem, which led to relentless disagreements among Thomas Jefferson and Alexander Hamilton. Both were members of Washingtons Presidential Cabinet, and soon after working together, these two men went separate ways because of their disagreements. They both soon gained national attention and support from publicly addressing their different views about the issues or concerns within our nation. Another issue that arose in the conflict was the refusal of Washington coming to Frances aid during the French Revolution and how did this affect his goal of national attention and support when public izing his Farewell Address? These were a few of the many actions that created tensions over disagreements that soon led to the dividing of the parties in our country. The growth of political parties had arisen in the early American Republic because of antagonistic views on the arrangement of a national government and its power, plus the arrangement of national policies under our new nation. The views between political successors were diverse when addressing their intentions to try to make our nation better. Tension between common people soon arose too, which was inspired by the conflict that started between prominent leaders over opposing views on issues within the nation. In Documents 1, 2, s views on Hamilton and Hamiltons views on Jefferson, and also the key differences between the Democratic-Republicans and the Federalists. Thomas Jefferson and Alexander Hamilton briefly address their views for...

Grandparents Raising Grandchildren Essay Example | Topics and Well Written Essays - 3500 words

Grandparents Raising Grandchildren - Essay Example In the present family system, where separation between the partners is becoming very prevalent, grandparents take the charge to rear their grandchildren. Moreover, due to work schedule or career of the parents or due to single parenting, grandparents come forward to support their grandchildren. The present article discusses in detail about the grandparents raising grandchildren, the problems both face, their struggle over various issues and achievements of the child. "Grandparents raising their grandchildren", "grandparent caregivers", "grandparents-as-parents" and "grandparent-headed families" are interchangeable terminologies which refer to the families where grandparents provide full time parental care to their grandchildren in the absence of the children's biological parents. In this era of recession where the people are losing their jobs at a much faster rate, parenting is becoming a big worry and therefore parents are becoming more inclined and turning to their own parents to rear their children because of several reasons including the financial insecurity and also because they are seeking jobs elsewhere and therefore grandparents raise their grandchildren due to the inability of the children's parents to effectively meet their parenting responsibilities. There are other conditions when grandparents become the full-time parent, may be either because of the death of the parent or a parent is away in the military, or because of the career of the parent(s) demand support to rear their kids, and rarely because of the grandparents living along with their children as a single joint family or under the rarest circumstances when the parent/s may be mentally ill, incarcerated, or merely and regrettably incapable of caring for their children (Proud Grandparents). In many Western societies grandparents have play a dual role- as care providers of their grandchildren and also as grandchild's parents. And therefore provide full-time parenting role for their grandchildren. This includes a number of changes in family structure and social conditions (Kornhaber, 1996). Grandparents raising grandchildren is not a new phenomenon. Historically, they have always stood to take over the care of their grandchildren in times of family crisis and have played major roles in raising their grandchildren (Kornhaber, 1996). The growing social phenomenon in USA showed 44% increase over the preceding decade in the number of children living with their grandparents or other relatives. According to the Census 2000 Supplementary survey between 2.3 and 2.4 million grandparents have primary responsibility for the care and upbringing of 4.5 million children (Hayslip & Patrick, 2003a). This phenomenon has captured the attention of researchers, service providers and policy makers in the USA, resulting in a number of interventions to assist grandparents raising grandchildren (Hayslip & Kaminski, 2005). The U.S. 2000 Census displays that around 2.5 million families with grandparents raising their grandchildren (Kornhaber, 1996). The number is on rise as many families do support other relatives, who act as parents, for e.g. raising their brother or sister's children or, even yet, raising their niece or nephew's children. It is an observation that at times grandparents are at work also and still raising their grandchildren. There is a kind of mental, emotional, or financial boding between grandparents and their grandchildr

Changing tax laws to reduce tax avoidance through the use of Research Paper

Changing tax laws to reduce tax avoidance through the use of partnerships - Research Paper Example Lipatov, (2011) argued that it is unfair for a common man earning a meager income that is just enough to sustain themselves to be charged every penny of his revenue whereas big companies and wealthy people are exempted through avoidance of taxation. Non-remittance does not only reduces government revenue but also brings the taxation system into disrepute therefore authorities charged with taxation needs to prevent avoiding tax or keep it within check (Desai & Dharmapala, 2006). According to PWC (2012), Majority of those involved in tax avoidance usually invoke section 88 and section 100 of the income tax act in order to shield themselves. Section 88 have therefore been barred from being referred to when the gain from the interest of partnership far exceeds the cost of the asset fair market value (Government of Canada, 2012). The budget proposals have also propose for the application of section 100 up to the point of sale of partnership interest to the person who is not a resident of the place in reference, this will however be an exception in a situation whereby is carrying out its activities through a permanent establishment (Mullainathan, Schwartz stein, & Congdon, 2012). A Partner should also be able to waive on behalf of all his partners within a three year limit for making a determination (2012 Federal Budget Commentary). The law should be clear enough according to Rosenberg (1989) because this will stop the taxpayer`s personal exertion income being taken as being income of the partnership and later being diverted as the companies` loss under the agency and management agreements. Reason being surpluses or net profits from those monies will be forwarded from that partnership daily to the group finance companies (Batt, 2012). The partnership acts should introduce various amendments to the taxes acts, that is according to the Blundell (2011) view. These
