Resulting trusts - Essay Example since there is no evidence that Joe retained a reversionary interest in the home.1 In Lohia v Lohia, it was established that by virtue of Section 60(3) of the Law of Property Act 1925, a resulting trust will no longer be inferred in the case of a voluntary conveyance.2 A declaration of trust can be created by word of mouth â€Å"or even inferred from conduct.†3 There were no words or conduct on Joe’s part that can be construed to represent an intention on his part to create a trust. The voluntary conveyance of the home will therefore be construed as an absolute gift to Jack which does not form a part of Joe’s estate and likewise Daisy will have no legitimate claim to it. The disposition of the shares in Dotcom plc to Eddie was a bare trust and as such will devolve with Joe’s estate. Eddie assumed the role of trustee and likewise treated Joe as the sole beneficiary of the trust during his lifetime. This is evidenced by Eddie leaving the share certificate with Joe and paying over dividends from the shares to Joe. Moreover, Eddie himself acknowledged that he was merely holding the shares upon trust for Joe. There is no escaping the conclusion that the manner in which the shares in Dotcom were purchased, held and treated was consistent with the requisite three certainties of a trust. These certainties are certainty of subject matter, intention as well as objects. The subject matter is the trust property, intention is words and conduct capable of defining the intent by the donor to create a trust and the objects are the intended beneficiaries.4 The presumption is that Daisy be the sole beneficiary of the shares in her role as heir to Joe’s estate. Joe’s gift to Jack for Emily’s medical problems appears to be a discretionary trust. However, the validity of this kind of discretionary trust can be challenged on the grounds that Joe’s words do not impose upon Jack a legally binding obligation. Rather, the words used most probably impose upon him

Development of a Leadership Plan Research Paper

Development of a Leadership Plan - Research Paper Example This has led to the emergence of several rehabilitation centers and organizations to assist drug addicts within Ohio State. Lome Counseling and Support Group are a volunteer association initiated by five members who had a passion to help drug addicts abandon their destructive activities in the society. It was started in the year 2000 and has grown immensely due to the support from the government, private organizations and well-wishers who had the passion to reduce the rate of drug use. The group is located in Ohio State and has several branches and support centers within the state which assist various groups of people involved in drug use (Schuckit et al., 1996). Lome is headed with a CEO named James Bond and a deputy director. The other three members are involved in the daily management of the organization and in various administrative posts within the association. All of the five members were initial drug users who had undergone rehabilitation and thus have the passion to assist ot her people engaged in drug use. Program Description Lome consists of various technocrats and experts within its premises who help in the rehabilitation of drug addicts. The program runs through various communities and targets specific people who engage in drugs and substance abuse for various reasons. Consequently, Lome targets drug dealers who sell the drugs to young people in middle and higher learning institutions (Hanson, Venturelli & Fleckenstein, 2011). The program first identifies groups of people and institutions who are at risk of using drugs such as alcohol, cocaine, marijuana among other drugs. Afterwards, the program rolls out plan of reaching them through the organization of workshops, sports, seminars and training program. During the meeting session, the program coordinators engage with drugs and substance users by discussing various negative impacts of drugs on the users and seeking their views. Thereafter, the coordinators of the program advise the youths on various ways of stopping using drugs. The program also incorporates involvement of the youths are the most affected in activities that make them exploit their talents and engage in constructive activities. For instance, the organization arranges sporting activities amongst schools, various estate teams, debates, seminars and various forms of competitions within the society, thus minimizing time available for the youths to engage in drug use (National Youth Network, 2011). The group takes various drug addicts to the several centers it has opened thus ensuring the youths are looked after during the recovery period. Relation of the Program to Selected SP Chapter Lome Counseling and Support Center mainly focuses on drugs and substance abuse in the Ohio State. This is a serious social problem within many societies since it erodes social norms set out to be observed by everyone in the society. This happens when the drug addicts rebel against parents, elder people or even their own family members and only associate with fellow drug users. This was the main reason for establishing the program within Ohio State. The program explores various means of curbing incidences of drug use among the youths who constitute a sizable percentage of learning students. Through the program, the plan is to provide both moral, emotional, physical

Martin Luther And His 95 Theses

Martin Luther And His 95 Theses Nailed to the door of the Castle Church in Wittenberg on October 31, 1517 on the eve of All Saints Day (according to Philip Melanchton, Luthers colleague in Wittenberg University), Martin Luthers 95 theses paved the way for the birth of a great spiritual movement called the Protestant Reformation. The Reformation ultimately signaled the end of the Medieval Age and the inauguration of modern times. What Luther intended to be a set of propositional statements to be debated upon over the abuses associated with the sale of the indulgences very soon became the key that unlocked the door towards the long-awaited reformation of the church of the late Medieval Christendom. The Sale of the Indulgences The doctrine of indulgences is peculiar to the Roman Catholic Church, unknown to the church fathers, and most importantly, to the apostles of Christ. It is basically defined as a certificate of forgiveness granted by a bishop or an archbishop within his diocese for the remission of the temporal punishment of sin both on earth and in purgatory, the alleged source of which was the surplus of merit and grace accumulated through the lives of Christ, the Virgin Mary and the saints of the Church. What most particularly attracted Luthers attention in this regard was the extravagant preaching associated with the sale of the indulgences in Germany by a Dominican friar Johann Tetzel. Tetzel was commissioned by Albrecht, Archbishop of Mainz and Magdeburg, to raise funds for the rebuilding of Saint Peters Basilica in Rome. As soon as the coin in the coffer rings, Tetzel proclaimed, the soul from purgatory springs. Luthers long quest for truth that resulted in his discovery of the biblical doctrine of justification by faith alone must have been the reason why he indignantly reacted to such a deceptive message that offered false hopes to those who bought the indulgences for themselves and their departed loved ones on account of their ignorance of the true gospel of Christ. The 97 Theses Before the 95 Theses Convinced that he must challenge the traditional views purported by the Roman Catholic Church for centuries, he published a set of 97 theses to be debated in an academic setting among his colleagues at Wittenberg University. The theses attacked many of the major tenets of the Church with a clear message in mind: that the gospel was entirely different from what had been commonly held. Luther expected the theses to cause a stir among the participants which in turn would allow him to divulge his great discovery. To his disappointment, they only mustered little interest. Martin Luther and His 95 Theses Despite such a cold response to his 97 theses, Luther composed another set of theses which he called The Disputation on the Power and Efficacy of the Indulgences, now popularly known as the 95 theses. Like the 97 theses, this new set of theses was also meant to provoke academic discussion among his colleagues in the university. They may have been an afterthought to a letter he sent to Albrecht through which he aired his disagreement on the sale of the indulgences. However, scholars are divided whether the Luther of the 95 theses was still a Roman Catholic clergyman at this time or already a Protestant Reformer. On the one hand, Luther appeared to have thought Pope Leo X was on his side in this matter. Some scholars even suggest (probably following the church historian Philip Schaff) that he was not protesting against the indulgences, but only against its abuse. On the other hand, a closer look at the document would reveal one thing for sure: what Luther was up against was not simply the sale of the indulgences but its theological underpinnings. As Princeton theologian Benjamin Warfield puts it, They constitute, in point of fact, a theological document of the first importance, working out a complete and closely knit argument against, not the abuses of the indulgence traffic, and not even the theory of indulgences, merely, but the whole sacerdotal conception of the saving process an outgrowth and embodiment of which indulgences were. While there may be apparent remainders of Roman Catholicism in the theses, they nonetheless assert the evangelical Protestant doctrine of salvation that refuted the sacerdotal system that was largely built on tradition instead of the Bible. In summary, the 95 theses proclaimed that indulgences cannot remit guilt as such a work belongs to God alone, that they are unable to make souls spring from the Purgatory, and that the truly repentant sinner has already received the forgiveness of God and is justified by faith alone.

Singing in the Rain Essay -- essays research papers

The hit musical "Singin' in the Rain" may possibly be one of if not the greatest musicals of all time. With it's tale of the film world of the mid 1920's and its creative underlining love story between Don Lockwood (Gene Kelly) and Kathy Selden (Debbie Reynolds), it provokes the interest of someone who would not generally be attracted to a musical. It is a classic masterpiece that set the standards that musical films of today will be judged by. It is a classic performance by the great Gene Kelly and displays outstanding performances by Debbie Reynolds and Donald O'Connor. As well as starring in this brilliant movie, Gene Kelly teams up with Stanley Donen to make their mark in film history. In my opinion, what set the stage for the level of entertainment that this movie contains is the opening scene. The opening scene set the role of sarcasm in the movie and gave the movie an immediate sense of humor. Four individual parts of movie making come together in this film to create a dynamic opening sequence. The basic principles of sound, editing, mise en scene, and cinematography collectively give this opening sequence a memorable quality that is without match. The opening of Singin' in the Rain takes place at the opening of the new movie "The Royal Rascal" starring Don Lockwood and Lena Lamont. There are famous people all around and their fans are loving every second of it. The fans' faces are full of joy and awe as their favorite actors and actresses enter the large building that will soon be showing the new movie. Soon, the two people that everyone in Hollywood is dying to see, appear in their stretched Rolls Royce and bring the crowd to its feet. As Lockwood and Lamont exit their luxurious ride they are received lovingly by everyone. They walk to the front of the building and are introduced to the crowd. Then the question is posed to Mr. Lockwood, "How did it all begin?" The answering of this question is what my paper will explain. I will attempt to break down the opening scene and show how it all started. By using tools of film such as sound, editing, mise en scene, and cinematography, this paper will show how the scene was made as well. Mise en scene played an important role in this movie as with any other movie. The properties of mise en scene were fully effective in the beginning flashback scene. At the beginning of Don Lockw... ...nd that the superimposed duo were taken from. They proceed to dance for a couple of minutes and when they are finished there is no reaction. There is a cut and we see a point-of-view shot in terms of Don and Cosmo to see that the audience is booing. This is the last scene before they actually get to Hollywood. Singin' in the Rain is the musical that all other musicals should be judged by. It tells a story that only others had dreamed of telling. Donald O'Connor, Debbie Reynolds and the great Gene Kelly help give one of the greatest performances of all times in a musical. With the help of superb editing, sound, mise en scene, and cinematography, this film cannot be topped. The fist scene of the movie creates an atmosphere that helps the viewer know that he/she will enjoy this wonderful classic. Throughout the movie there are surprises and fun that makes this a movie that people will want to watch again and again. Gene Kelly said it best when he said, "Dignity, always dignity." That is what this movie has from beginning to end, dignity. The best thing we could possibly do is forget about our worries and just start Singin' in the Rain. Courtesy of Chew (1995) U. of Maryland

Questions asked from the managers Essay

The following questions are those asked from the managers of the IT corporations. Each and everyone of them were also asked to give a brief company profile before the questions about blogging were asked. Company Profile 1. Name of Company: 2. Year Company Started: 3. Brief History of Company 4. Nature of Company’s work 5. Number of company employees: 6. Target market of the company: Questions on Corporate Blog 1. What does the company offer? a. Services – (what services and for whom? ) b. Products – (what products and for whom? ) 2. Since when did your company start engaging in corporate blog? 3. How much does your company spend for the operation of your corporate blog? 4. What was the effect of corporate blog to your corporation 5. Is blogging effective in making your customers understand more about your company? 6. Does blogging make understanding your services easier? 7. Communication with Customers a. Did you receive more client feedback when you engaged in corporate blog? b. Are your customers more informed about your products when you engaged in corporate blog? 8. Communication with Employees a. How many of your employees engage in blogging? b. What are your rules regarding employees blogging? 9. Did you integrate your missions, visions, and goals into corporate blogging? 10. Did you consider the risks involved when your corporation or company started adopting corporate blog? If yes, why does your company still continue engaging in corporate blog? 11. Are the solutions which your company pursued, effective in reducing the risks of corporate blog? If not, what other solutions do you think should be done? 12. What have been the advantages of corporate blog for your company? 13. What have been the perceived disadvantages of corporate blog for your company? 14. What were the problems faced in engaging corporate blog? 15. Is corporate blogging better than written media into bringing your services closer to the customers? 4. 3 Analyzing obtained data The data obtained from the interviews have been tabulated and themes and trends from such qualitative data would then be identified, and analyses would then be formulated. The data obtained from the questionnaires will be analyzed using the Likert scale. The primary tool used to examine Likert Scale is by the use of graphical analysis. Since the frequency distribution can visually be seen in the graph, it is easier to explain the results. The trend represents certain patterns that match with the frequency distribution. The Likert scale is a unidimensional scaling method. Unidimensional concepts are generally easier to understand. Its either something has more of it or less (Trochim 2006, http://www. socialresearchmethods. net/kb/scalgen. php ). Since the aim of the research is to identify whether the receptiveness of corporate blog to employees, executives and the corporation as a whole is better or worse, then a unidimensional scaling would be a good measurement for the research. 4. 4 Other Resources Secondary resources are also critically used in this project, which mainly include news, journal articles and books. Internet and Email will be as the communication and research tools for this project. The collected data will be coded and analyzed under the theoretical framework and prior reviewed literature. According to Coffey and Atkinson (1996), coding is the process of condensing the bulk of data sets into analyzable units. Coding and analyzing data based theoretical concepts has the important role of enabling rigours review on our data. Therefore, the collected data will be coded and analysed under the theoretical framework and prior reviewed literature. 5 Discussion 5. 1 Research expectation and risk The author will discuss the outputs from the case study, interviews and questionnaires. Each case study will be discussed here in full detail. Blog contents from the corporate blogs of each company will be evaluated and discussed. The research study is able to seek: why did the company considered blogging? What are the advantages and disadvantages from setting up a corporate blog? The expectation data obtained from the questionnaires will also be presented and discussed. Results obtained through the Likert scale will be interpreted. Results are also related to previous researches and theoretical issues discussed in the introduction and literature review. The author will give a brief introduction to the uses of blogs, corporate blogs, its advantages and limitations, and the issues surrounding corporate blogs, which includes privacy or information leakage of the corporation because of the freedom, entailed in corporate blogging. To which we can now generate our prediction of corporate blogging with the analysis of its strategic management implementation (rules and regulations), the perception of employees and employers, and our own analysis as to how corporate blogging can elevate the communication process among a business organization. The author expects challenging the blogging system as an entity of information and as a communication medium to delimit its disadvantages and provide better means of communication for the business sector. Assuming that results are as predicted, we can now generalize the discussion. Note, however, that different companies have different cultures and strategies in corporate blogging; thus different results would be yield, and themes would have to be established in order for data to be qualitatively analyzed. Having the prediction of the future of corporate blogging may be a challenging step but I think it is feasible in this case since we can generate information regarding how the corporate blogging system can improve and be able to overcome the challenges of advanced technology. 5. 2 The limitations of the study On major limitation of the study is that only IT companies are to be considered in data gathering. It is possible that other companies may have a different culture and perception on corporate blogging. Future research may focus on determining the perceptions of companies other than IT and compare its results with the results obtained from this study. Also, the study only analyzed the perceptions of bloggers on corporate blogging. Studies on the perception of nonbloggers (or those who have blogs but do not post regularly) may be carried out to give a more generalized rate of acceptance of blogging as a new kind of innovation. There is also a restraint in Rogers’ Diffusion of Innovation Theory. It may be the most widely used theory in both individual and organizational IT adoption researches but none of the five predictors (relative advantage, compatibility with existing values and practices, simplicity and ease of use, trialability and observable results) made Jeyaraj et al. ’s (2006) list of best predictors for the aggregate IT adoption construct. Another limitation of this research is that blogging can result in legal problems because of the lack of blogging management. The integrity rules for protection and management are expected to established immediately.

Critical Analysis of Health care system in Canada

Critical Analysis of Health care system in Canada Health care is a basic social necessity that is critical for people to acquire good health status despite their difference in social, political, and economic levels. The health care system in Canada has made significant steps in ensuring that Canadians receive health care services without undue discrimination.Advertising We will write a custom essay sample on Critical Analysis of Health care system in Canada specifically for you for only $16.05 $11/page Learn More Accessibility, universality, portability, comprehensiveness, and public administration are five principles that guide the health care system of Canada in delivering quality health care services. However, due to societal differences in social, economic, racial, and political backgrounds, discrimination does arise in delivery of health care services. In Canada, Aboriginal people experience discrimination in health care by virtue of their race since they do not receive equal treatment. According to Un ited Nations Human Development Index, health care of Canada ranks among the top nations, but health care of Aboriginal people ranks 68th in rural reserves and 36th in other parts (Tang, Bowne, 2008, p.110). Hence, racism among others factors such as social exclusion, poverty, and discrimination have contributed to inequitable access to health care by the Aboriginal people. Therefore, this critique examines how â€Å"race† and racialization process perpetuate inequality in health care system. Ethnographic Study The ethnographic study focuses on factors that influence decisions of Aboriginal patients when seeking health care services from Emergency Department in urban hospitals. The study hypothesizes that racialization affects how doctors and nurses deliver their services to Aboriginal people. To collect robust data from interview and participant observation, the study sampled 82 participants; 38 were staff, which consisted of physicians, nurses and social workers, and 44 pat ients from Fast Track, a division of Emergency Department. Out of the 44 patients, 10 were Euro-Canadian patients and 34 were Aboriginal patients. Tang and Browne (2008) point out that theoretical sample was necessary to expound racialization of â€Å"Aboriginality† among Aboriginal patients (p.112). Diversity of samples provided for comparative analysis of results with respect to racialization and accessibility of health care by Aboriginals people.Advertising Looking for essay on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Ethnographic researchers interviewed and observed Aboriginal patients for about 30 to 60 minutes at the Fast Track division in the Emergency Department. To collect reliable data, the researchers interviewed and observed Aboriginals patients in private places such as clinical examination rooms and meeting rooms. Interviews and observations of physicians, nurses, and social workers also took places in the same place and did last for about 15 to 30 minutes. Tang and Browne (2008) assert that the study aimed at analyzing process of racialization in a health care environment (p.113). Process of racialization is so complex because it has many confounding factors such as economic, social, and cultural factors. Effective analysis of racialization process involved the researchers, Emergency Department staff, and collaborators who confirmed that the data collected resonated with daily experiences that they constantly encounter. Racialization Racialization has a significant impact in perception of images attributed to certain people. Ideally, racialization involves conceptualization of â€Å"race† as a basic and natural way of categorizing people according to their racial attributes. Dominant race has racialized perception of Aboriginal people because of their cultural, historical, social, and economic backgrounds, thus negatively affect their accessibility to healt h care. Tang and Browne (2008) argue that notions of â€Å"Aboriginality† emanate historical power relations between non-Aboriginal and Aboriginal populations, thus creating racialized images that negatively depict Aboriginals (p.114). Hence, perception of Aboriginal people based on racialized Aboriginality explains tough experiences that they encounter as they struggle to access health care. Racialized Aboriginality is a concept that has historical origin, and plays a considerable role in shaping political discourses regarding racialization of Aboriginal people, in the context of health care. Ethnographic study revealed that most Aboriginal people experience discrimination in health care system due to racialized images that depict them negatively. A case scenario describes how Aboriginal patient went to two different Emergency Departments in search of treatment of his chronic headache.Advertising We will write a custom essay sample on Critical Analysis of Health care system in Canada specifically for you for only $16.05 $11/page Learn More In the first, the physician assumed him as drunk, hence did not diagnose any medical condition after brain scan. Since the physician gave him pills, but the pain did not relieve, the patient went to second Emergency Department where they did brain scan and realized that the patient requires urgent operation. Such a case scenario of the Aboriginal patient portrays experiences that Aboriginal patients undergo when they seek medical attention from health care system. In the first Emergency Department, the physician based his diagnosis of severe headache on racialized perception that Aboriginals people are drunkards. Tang and Browne (2008) assert that, racialized images of Aboriginal people have negatively influenced how they obtain medical services from health care system (p.115). Therefore, this confirms that health care providers perceive Aboriginal people based on racialized assumptions that depict them as drunkards, poor, and abusers of substances. Egalitarianism Although the health care system of Canada upholds egalitarian principle, which supports equal treatment of everyone, racialization hinders Aboriginal people from accessing health care services. Egalitarianism has its basis in ethical principles, which ensure that everyone receives equal treatment in spite of differences in social categories that society attaches to people. According to Tang and Browne (2008), application of egalitarianism in health care assumes that health care providers are sensitive and rational when exercising their roles lest they succumb to racialized perceptions of patients (p.117). Mere rhetoric of â€Å"treating everyone equally† does not reflect how Aboriginal people experience discrimination due to racialization. Therefore, health care providers should avoid racialization of Aboriginal people by upholding ethical principles that guarantee just and fair treatment of everyone, and prevent discrimination in health care practice. Racial profiling indicates that racialization is a hidden process that Aboriginal people encounter in health care system when they seek medical services. Although racialization is real, non-Aboriginal people always tend to deny it because they assume that everyone accesses health care equally. Most people presume that social issues of race and racism no longer exist in society because they seem obsolete, thus; they overlook the fact that there is racialization of Aboriginal people in health care system.Advertising Looking for essay on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Tang and Browne (2008) explain that, racial profiling is a discourse that government and media articulate to rationalize racializing practices among diverse communities (p.118). Hence, racial profiling of Aboriginal people indicates that they experience enormous challenges in their lives as they struggle to reclaim their racialized images that contribute to discrimination in health care system. Conclusion The health care system of Canada is advanced because it advocates for egalitarianism, an ideology which ensures that everyone receive equal treatment in health care. However, racialization of Aboriginal people has hindered them from accessing health care services as their counterparts from other communities. Ethnographic study revealed that racialization is a form of discrimination that relegates Aboriginal people by depicting them as drunkards, poor, and substance abusers. Assumptions and stereotypes that health care providers have relating to Aboriginal people determine the natur e of treatment that they receive from health care system.

EU LAW Term Paper Example | Topics and Well Written Essays - 1500 words

EU LAW - Term Paper Example This implies that there was the evolution of certain relevant legal principles from a national level to conform with European Union laws and systems. The potential conflict led to the creation of the General Principles of European Union Law. The General Principles created a framework through which the new legal instruments of the common market could be streamlined and applied in all national jurisdictions (Tridimas, 2006). The General Principles include a set of concepts that guide the courts in the enforcement of European Union Laws (Schwarze, 2006). They are invoked to ensure that the potential tensions between EU law and local laws are minimized. More importantly, they are applied to ensure that the spirit of the European Union law is honoured in cases. They main concepts in the General Principles of EU Law include fundamental right, proportionality, certainty, equality and subsidiarity (Foster, 2011). Individuals can therefore request for review of their cases on the bases of these principles when they feel it is not fully honoured. Article 5 (3) of the EC Treaty states that â€Å"Any action by the Community shall not go beyond what is necessary to achieve the objectives of this treaty†. This implies that the interpretation of EU law should not be done such a way that people will incur disproportionate hardships. In R V Intervention Board ex parte Man (Sugar) Ltd1, a company was to incur over a million dollars in fines because their application for a permit delayed by a few hours. It was held that the fine could not be imposed on the company because of this principle. The European Union honours the principles of liberty, democracy, respect for human rights, fundamental freedoms and the rule of law amongst Member States (Article 6). This means that the fundamental rights of individuals must be respected in every case. Courts must be sensitive to the rights of humans in cases that are brought

Impact on second language learning Essay Example | Topics and Well Written Essays - 750 words

Impact on second language learning - Essay Example rs: an innate capacity for acquiring language or Language Acquisition Device, containing the "universal" features found in all languages and the â€Å"critical or optimal age hypothesis.† Non- linguistic factors which are considered when talking about language acquisition are motivation, opportunity; and language learning ability. (Fantini & Reagan, 1992) According to recent studies (Dornyei, 2005) L2 motivational self system is the equation of the motivational dimension of "integrativeness/integrative motivation" with the "ideal L2 self which is person’s hopes, aspirations, desires or other desired attributes. If ideal self is interested in the mastery of an L2, then one has "integrative" disposition (according to Gardners (1985) terminology). (Csizer & Dornyei, 2005a) "Integrative" disposition supposes sincere interest in the L2-speaking community and its life, culture and routines. Integrativeness reflects a positive outlook on the L2 and its culture which makes learners desire to integrate themselves into the L2 culture and L2 speakers’ community. (Csizer & Dornyei, 2005) If the L2 community has no respect among learners – it is associated with negative characteristics such as poverty or crime - it provides less motivation for students to learn the language of this community. The researcher of attitudinal basis of language attainment Spolsky (1969) arrived at the conclusion: â€Å"One of the most important attitudinal factors is the attitude of the learner to the language and to its speakers" (p. 274 in Csizer & Dornyei, 2005) The attitude to community contains some constituents: attitudes toward having direct contact with L2 speaker or opportunity to travel to the country of origin and on the other hand cultural interest or appreciation of cultural products related to particular L2 and spread by the media - movies, music, magazines and books which provide indirect contact with L2 community. L2 cultural products play an important role in acquiring

Cause and effect Essay Example | Topics and Well Written Essays - 1000 words

Cause and effect - Essay Example on of marital relationships is strongly associated with aggression, whose presence may cause separation or divorce within a marriage’s first 4 years. Studies show that couples who exhibit aggression in their marriages would be more likely to end their marriages through divorce or separation than those that do not (Fine and Harvey 98). Newlyweds are particularly at risk as they show higher levels of aggression. Partners facing marital violence mostly downplay the violence by making excuses for not seeking help for the behavior, opting instead for divorce. The link between marital dissatisfaction and divorce is strong. Couples that are unhappy with their union are at an increased risk of divorce than those who are happier. Fine and Harvey support this postulate, noting the risk to be higher if the husband is the unhappy one of the couples (97). The risk when the wife was unhappy was noted to remain the same as when both are happy. Marital dissatisfaction may come as a result of the two people growing apart for various reasons causing them to lose touch of each other. Adultery is one reason that may cause couples to grow apart as it causes mistrust to creep in. Such mistrust causes couples to prefer to be apart, hence divorce. Additionally, alcohol and substance abuse has led to the dissolution of many marriages. Alcohol consumption, particularly in excessive amounts, leads to lack of control and could lead to physical or psychological abuse which strains marriages (Sember 6). Alcoholics would not aware of the damage caused to the family, especially because parenting would be left to one partner. A marriage with one or both partners engaging in substance abuse would be 4 times more likely to end in divorce than one where the partners do not (Fine and Harvey 97). A majority of men divorcees report spousal abuse as the cause of their divorce. Finally, economic challenges accelerate the risk of divorce. Studies have shown that couples are at a high risk of divorce

Project Essay Example | Topics and Well Written Essays - 1000 words

Project - Essay Example It is also important to note that some motors produce immense output power, but cannot be efficient enough. It is under such conditions that people make use of H Bridge in the efficient control of the Motors’ direction. Project Fundamentals An H-bridge circuit refers to a power circuit that is electric, and used in the control of electric motors like DC motors used in automotive applications. The H-bridge functions in controlling the direction and speed of the motor by allowing a limited amount of current to flow in the motor through the right direction (Barrett, 2012). It is made up of four MOSFETs, which are under the control of control signals of the (PWM) Pulse Width Modulation. The original design of the DC motor control incorporates Multisim LabVIEW co-simulation that permits the performance of the entire system to be authenticated on the desktop. The motor has such parameters as inductance, the load weight, and armature resistance for accurate verification of the result s of the performance. The use of a multisim-labVIEW co-simulation ensures that one shall not have to digital and analog systems separately. During the implementation stage of the model, the circuitry of the analog can be transferred for photocopying to the Ultiboard. Such a transition between the Ultiboard and Multisim makes sure that there is a precise convey of simulated designs. The graphical code of control is moved to a Single Board Rio 9695 target. This is usually an acquisition device and an embedded control that puts together a FPGA that is user-reconfigurable, a real time processor, and input or output of printed circuit board. The four MOSFETs needed in designing a H-bridge can be demonstrated with the diagram below. Two of the MOSEFETs should be of P channel (IRF9540N), while the other two should be of N channel (IRF540N). They should be designed in such a way that the motor’s rotation is controlled through an on-off-on switch. The motor’s closed-loop contro l starts through inputs that are user-defined such as the necessary step size and speed. This message is resent to the Multisim design through the co-simulation terminals. Negotiations between labVIEW and Muiltisim occur as a guarantee in conversation and accuracy for both sides. In case of abrupt drops or peaks in Multisim, negotiation in time-step allows Multisim to alter the available time-step to view the drops and peaks. A point by point model between digital systems and analog circuits results to an advanced system both in accuracy and behavior. Once the verification of the system design has been made with Multisim and labVIEW co-simulation, the complete circuit can be moved to Ultiboard for routing and layout. List of Components The list of components used in the circuit includes: MOSFET P Channel (IRF9540N) – 2 MOSFET N Channel (IRF540N) – 2 Motor – DC 6 volts Battery – 9 volts Switch – 1 Connecting Wires and Strip Board Controlling the Mot or The control of the motor is done through the two ways switch connected to Q1 and Q3 of the circuit. If a signal is sent to Q1the motor is stimulated to move in a forward direction, while on the other hand, if a signal is sent to q3 the motor is stimulated run in a reverse direction. It is never possible to sent signals to both Q1 and Q3at the same time because of the use of on off on switch. This can be summarized using the following table: Q1 Q3 Stop 0

Information mangment Essay Example | Topics and Well Written Essays - 1000 words - 1

Information mangment - Essay Example Technology has changed a lot; from the way people manage their information to the way data is stored and also to the way it is distributed among people. Why the topic is important This topic is important because many people are not aware that they manage information in more than one way every day. Information management does not only involve the collection and management of data from different sources (Beynon-Davies, 56, 2009). It also involves the distribution of this information to one or more different other sources or individuals. Information management in business is used to do different things. The information management software is used to assist in running the business. An information management software in business helps connect a business with access to database servers, business intelligence, management of contents and also the protection of data from other sources that might cause data discrepancy. My argument in this essay Information management is an issue that is very important in business and the whole world as a general since it enables the secure storage of data, collection and management and also the distribution (McAfee, 300, 2009). Without information management, there would be an unstable system of business, technology and living as a whole. The essence of this essay will be to center on the significance of data technology in business and life as a general. Most people overlook the concept of information technology as something that would not aid them in their day to day lives. When it comes to developing data and managing it, it is very crucial that there be a source to which one can manage the data. Theories Since management means the overall organization, control, planning, structure and organization, controlling, processing, evaluating and reporting of all the information actions that transpire daily, it is then safe to say that information technology helps to meet client objectives and enable corporate functions in the delivery of inf ormation to people. In information management, there are numerous stipulations used in explaining the term. There is information retrieval, information seeking, knowledge organization, and the society. Without these four key aspects, then information management would cease to have meaning. Information management has been taken into an assumption by many, and the purpose of this essay is to show individuals that information management involves a lot than people may think. In an organization, the ability to process certain information brings out the power of a company to perform. An organization’s ability to process information strengthens a company’s core and management practices. Taking a look at social media, the quantity of data that is substituted in a single second can illustrate the level of management of data that is used. Social media is a networking site that enables people to interrupt with each other and share things like photos, videos, information pertainin g to themselves and many more stuff. Much information that is exchanged and also a lot of information are stored in the servers since social media’s contain a lot of people (Boddy, Boonstra & Kennedy, 100, 2005). With such information, it is crucial that an information management system be used to deal with all the data in the servers. Data pertaining to the people of social networks, the information that they exchange on a daily basis is stored in secure locations so as to maintain the
