Movie Analysis Othello - 934 Words

Oliver Parker s 1995 movie â€Å"Othello,† starring Laurence Fishburne, Irene Jacob, and Kenneth Branagh, is an adaptation of Shakespeare s play that remains faithful to the original text, while using the advantages of the big screen and modern day editing to present the story in ways that would be impossible for a stage performance. The movie remains, for the most part, faithful to the story and language of the play. Although some of the text has been cut, the film still utilizes the language of the play rather than updating the script to modern English. To make the material more appealing to a modern audience, Parker uses flashbacks and dream sequences to provide visuals and enhance certain scenes of the text. The film also includes multiple sex scenes, providing a physical element to Othello and Desdemona s love that is not included in the text. Parker s film effectively brought the characters from the text to life, and was an impressive and faithful production. In the play, Act 1, Scene 3 is an important scene in both validating the love of Othello and Desdemona, as well as showing the manipulative and callous nature of Iago. When reading the scene in which Othello is brought before the Duke and Senators to face the accusations that Brabantio has brought against him, it is clear that Othello is steadfast and authoritative. He is an important figure in his society and has done nothing wrong. The lines where he explains how Desdemona fell for him should beShow MoreRelatedDifferences Between Film And Othello1503 Words   |  7 PagesThroughout the years the play Othello by William Shakespeare has been adapted both on the screen and on stage many times.

Select a company from the Australian Securities Exchange website and download the 2014annual report. Evaluate the categorisation and treatment of liabilities in the annual report. 4. Comment on the relationship between the measurementof liabilities and decision useful information with examples from your selected annual report. Answer: Abstract The research topic of the definition of liabilities and their measurement with regard to an ASX listed company Myers Holdings Limited has been presented to us for the Summer Semester 14-15. Herein, the entire assignment has been segregated into four different components, wherein the first part of the assignment caters to the need of understanding the definition of liabilities as presented by the Australian Accounting Research Foundation (PSASB and AASB 1998). The second part of the assignment deals with the detailed discussion about liabilities and the existing issues with its measurement, with concern to the current IASB framework (Bullen, Johnson and Crook 2005). As we go on further into the study of this paper, we observe that the third part of the assignment completely takes into being the classification and treatment of liabilities from any company listed in the Australian Securities Exchange (ASX). We have selected the company of Myers Holdings Limited (Read as MYR on ASX) for the study of the classification and treatment of liabilities from the downloaded report of 2014 (ASX 2014). The fourth and the final part of the assignment revolve around the relationships between measurement of liabilities and decision-useful information along with selected examples from the 2014 Annual Report of the Myers Holdings Limited. Overall, the assignment attempts at delivering the concept of liabilities, their measurement, presentation and utility for the key executives of any company in finalizing and concluding decisions about significant business operations. The reader comes to the accrued knowledge of what are liabilities as per the Australian Accounting Research Foundation, and how can the relevant knowledge of measurement be employed to the understanding of the facts mentioned in the 2014 Annual Report of Myers Holdings Limited. Introduction Myer Holdings Limited has been into operations for over more than 100 years in Australia, into the style, fashion and lifestyle products. It is said to be the largest departmental store in the entire sub-continent of Australia and is said to have generated a whopping $3.1 billion turnover in 2014, and is the largest departmental retail chain across Australia with over 68 retail outlets and the most recent venture into the digital and mobile platforms with the revolution in internet. 11 core products are offered under the umbrella of this brand, which include the likes of menswear, women wear, lifestyle products and so on. The categorization and treatment of liabilities in the 2014 balance sheet of the Myer Holdings corporation has also been analysed herein, and a small explanation given for the same. The definition of liabilities and calculation of liabilities are significant in the understanding of the business decisions which Myer undertakes for undertaking right business decisions. Certain issues with measurement of liabilities with the context to the IASB framework, which is still under the creation of standards from the 1989 framework it had created initially. Finally, the establishment of the relationship between the measurement of liability and the business decision-making has been taken in herein. Body (1) In the most simplest of definitions, liabilities refer to the future sacrifices of economic benefits that is compulsorily obligated on the concerned entity to the other entities in the same business line, as a consequence of any past business transaction or past events (PSASB and AASB 1998). The Public Sector Accounting Standards Board (PSASB) of the Australian Accounting Research Foundation (AARF) and the Australian Accounting Standards Board (AASB) could not have been able to define liabilities in any simpler language. Any entity in order to run its business operations are required to operate it under the credit model apart from the input of liquid cash (Department of Economic and Community Development 2010). This is so, considering the dynamic turnaround time businesses are adopting these days, with consideration to rapid globalization taking place across the world. Companies these days face the possibility of dynamic growth opportunities and hence they are willing to operate under the consideration of supplying credits, for a particular time period, either on good faith, or for the purpose of availing the existing business operations. These transactions occur on credit and hence this turns around to be the definition of liability (Baskerville 2011). In totality, there are three different kinds of liabilities: Current Liabilities Non-current liabilities Contingent liabilities The following are the various types of treatments to the above mentioned types of liabilities. 1. These are short term loans or liabilities which must be paid within a year of their birth. They are reflected under the current liabilities head of the liabilities section of the balance sheet of the company. On the successful payment of these short-term obligations, they are written off the companys books of accounts, and the balance is debited then. Examples of current liabilities are payment due to suppliers, accrued taxes, rent and interest, and profitability materialised and collected in advance. 2. The examples of long-term liabilities are mortgages amount on property, bank loans and lease obligations for vehicles or any major business equipments. These are also written under the long-term obligation headings of the liabilities section and generally take more than one year to be paid off (The State of Queensland 2015). 3.The contingent liabilities are the companys back-up funds for an emergency situation like a case law filed against the company or any environmental law suits slapped over the business operations of the company. Such contingent liabilities are however not noted under the liabilities (short or long term) section of the Balance Sheet of the company. Generally, companies create a separate fund for the same, and include the same under the Notes section of the Balance Sheet of the companies. (2) It must be noted that after the creation of the business, profits can only be earned through transactions, and however, at the same time, earning these profits require certain capital inputs. At times, when the business houses are incapable of inserting a separate fund for the same, business take goods from the suppliers on credit in return of favour of delayed payments through cash, kind, or business goods (Baskerville 2011). Along with the owners fund (equity fund), the business also receives certain other funds from suppliers and creditors for the purchase of assets with which the business is intended to continue. These are termed as liabilities for any business house. The concept of liability come from the accounting entity assumption and under such an assumption, it is taken into consideration that the business entity is completely a separate entity and all transactions of the business are identically different and separate from the personal transactions of the owners of these businesses. Through such an assumption, the credibility lies in the true reflection of the financial details and facts-figures of any business-house at any given point of time (Baskerville 2011). Speaking about the recognition of a liability, the following facts can be put forward. A liability is only recognised if and only if the following conditions are met: 1.There is a definite future compensation of economic benefits in order to repay for the present reaped benefits by the company in terms of goods or services, whatsoever be the case (IFAC 1996). 2.Secondly, the mannerism of the calculation of the liability amount must be fair and reliable. This means that the factors of inflation and other such relevant aspects must be taken care of prior to the birth of such a liability (Australian Accounting Research Foundation 1995). Speaking about the IASB Framework, it must be mentioned and taken into consideration that in order to recognise a liability, it does not have to be an obligation which is due as per demand, rather than that, it stands out to be under a framework wherein, it becomes due as soon as the obligation arises (ACCA 2011). Thus, under the given frameworks of IASB, it is mandatory for the acceptance of liability to erect and come out as reflected under the financial statements as soon as it has arisen. Although this comes out to reflect the true and actual reflection of the financial health of any business, sometimes, it becomes adversely aggressive with the financial health of the business and the entity may not receive positive reviews from auditors and third-party clients who are even vaguely interested in the business operations and results of the entity in concern (Lott, Knubley and Clark 2013). Thus, for instance, IAS 37 (International Accounting Standard 37) of Provisions, Continent Lia bility and Contingent Assets is thoroughly in line with the IASB Framework and would require for the acceptance of the decommissioning cost of the rig oils in future. As soon as the rig oil locations are selected and the rigging procedure begins, the cost for decommissioning the same is arisen at the same time, and reflected as a non-current liability in the books of accounts of the concerned company, at the cost of the present value of money (Whittington 2008). Another major factor which really affects the measurement of liability is the entire structure of creating frameworks by the IASB (Bence and Fry 2003). IASB still presently uses the 1989 Framework for the Preparation and Presentation of Financial Statements which is deemed to be obsolete in the current accounting and business scenario. This leads to very limited guidance on the application of the 1989 framework to justify the appropriate measurement methods of the arising liabilities for any business. (3) The treatment of liabilities is a multi-dimensional concept. Herein, one has to take care that the differences between the maturity of assets and liabilities are taken care of, and not huge differences exist (Holton 2014). The entire aspect of ensuring the right balance between the maturities of liabilities and assets requires the primary understanding of what liabilities a company incurs in its year long process of business operations. Although, it is a continuous process, and therefore the accounting managers must take care that as soon as liabilities are incurred, the cash flow from these liabilities are rightly invested in assets which give best maturity returns as well as within the stipulated time (Myer 2014). Prior to segmenting the liabilities section of the 2014 financial report, it must be understood that the CEO considers Myers to be a complete store and product group, and has marked that the Myers Holdings Limited conducts its business operations in the departmental retail sector in Australia (Myer 2014). The company selected herein is the Myers Holdings Limited, which is existing in the retail industry and is statistically Australias largest departmental store, with a turnover of around $3.1 billion Australian Dollars for the year ending 2014 (Myer 2014). The company mainly deals in 11 core products which include the likes of men-wear, women-wear, child-wear and so on. The consolidated Balance Sheet for Myers Holdings Limited for the year ending 2014 has been prepared as on July 26, 2014 and hence all the conclusions and findings are thoroughly based on such annual report of the Balance Sheet as on 2014 (Myers 2014). In the financial reports of the 2014 financial period, we observe that Myers Holdings Limited has segregated liabilities into two divisions, number one being current liabilities and the second being non-current liabilities. Under the current liabilities, we have various sub-headings which are termed as trade and other payables, derivative financial instruments, current t ax liabilities, provisions, deferred income and other liabilities whereas on the other hand, under the non-current liabilities are mentioned sub-headings like borrowings, derivate financial instruments provisions, deferred income and other liabilities (Myers 2014). Under the current liabilities section, we notice that the derivative financial instrument of forward foreign exchange contracts has been applied (Myers 2014). A total current liabilities with respect to derivate financial instrument comes up to 5,253 ($000) When it comes to this, we must validate the application of such a derivative program. US Dollars or other currencies are purchased in bulk against the maturity of the payment from the goods sold on credit. The total payables are calculated at the present value rates, and the exclusion of interests-bearing. The total trade payables have been calculated as an addition of trade payables and other payables, the amounts of which are 203,473 ($000) and 224,593 ($000). Under the provisions of the current liabilities, we have the addition of employee benefits, workers compensation, sales returns and other current liabilities, a sum total of 82,167 ($000). Under the non-current liabilities section, we notice that an amount of 3,401 ($000) is present which accrued due to the interest rate swap contracts. We have the additions of employee benefits, fixed lease rental increases and other provisions, summed up to the total of 14,039 ($000). (4) The concept of accrual accounting is pretty much in the norms of the financial accountability of majority of the business organizations, in fact, in all organizations as such overall (Rowles 2004). The measurement of liabilities is in an important contributor to both the inner budgeting process, as well as, the external third party dealing aspect. They have been completely imbibed in the operations management of business organizations in nations like the UK, New Zealand and Australia, and in fact, have also become the jurisdiction laws in the States. The purpose of these measurements of liabilities is to provide a true reflection of the ongoing application of these sources of liabilities and their physical investment into assets for the organization, for sustaining the business operations in the long run (Rowles 2004). The correct measurement of liabilities and the application of these sourced funds in the long and short run for business operations are a clear and specific indica tion of the performance of business houses. The presence of these measured liability also paves the path for a definite investment model into assets, which further assists the decision making process overall. In the concerned organization taken by us, which is the Myer Holdings Limited, we observe that the total payables amount of 428,066 ($000), is used to create an inventory balance of 376,763 ($000) and at the same time, the total receivables of 30,133 ($000), apart from the cash transactions which were employed to create trade for Myer Holdings (Myer 2014). Thus, the relevant significance of the right investment channels is guided by these measurements of liabilities whether done through the fair value measurement or the present value measurement methods (Financial Accounting Standards Board 2013). Therefore, the management is continuously aware of which measurement methods are more practical and relevant to taking the right business investment patterns through the experimental study of a particular period. One can take the one-by-one study of the cash sales, and credit sales and the consideration of the turnaround period to gather vast information as to which is leading to higher gen eration of profitability and subsequently liquid cash-in-hand with Myer Holdings. Further, the investment into derivate financial instruments and their calculation are also assisting the management of Myer to calculate the expected foreign forward contract returns through the investment into US Dollars or other currencies. In order to safeguard the future rate of foreign currency and offset any unnecessary loss possible, Myers is involved with these foreign forward contracts wherein a certain amount of foreign currencies are purchased for the rightful investment patterns. Taking into consideration the Government imposed tax liabilities for Myer or any corporate house whatsoever, it can be stated that the tax calculations are completely an important part of the entire business operations as they give the company an insight into, how much tax obligations are on their head (Rowles 2004). The calculation of tax considerations come up to 7,321 ($000) for the accounting year of 2014, and Myer is now aware of the current tax obligations it has. This will further assist Myer in studying how much amount of business operations lead to the current tax obligation. Therefore, a further detailed study would assist Myer in undertaking tax planning activities in order to lessen the burden of income tax obligations. Additionally, majority of the financial boards like AASB and CFA are recommending the application of Fair Value as the right measurement methods of financial liabilities, as they reflect a true figure on the economic reality of the business organizations (CFA Institute 2010). The fair value measurement of liabilities will lead to the right decision making with respect to the future amounts, timing and riskiness of liabilities which might arise in future. For instance, in the 2010 balance sheet of Myer Holdings Limited, we notice that the borrowings of 422,030 ($000) are valued at fair value (market value) which otherwise would under-compute the total non-current liabilities, leading to the reflection of an untrue figure. This might induce Myer Holdings to take in more borrowings, leading to higher debt obligations in future. Conclusion In order to conclude the assignment I would like to restate the facts, figures and points mentioned above, in the individual sections of the assignment. Primarily, the definition of liabilities and their measurement have been spoken about, wherein; we have defined liabilities as the future compensation of economic benefits which are reaped at present. In the second part of the assignment, we have further discussed as to what are liabilities and the existing issues with the current framework advocated by IASB have further been discussed. The framework does not stand to have any authoritative stand on the guidance on how these standards for the measurement of liabilities are to be formulated; rather they follow a 1989 framework as such, with slight modifications in the 2010 framework. The selected company from the Australian Securities Exchange is the Myer Holdings Limited which has categorized and segmented liabilities based on the current standing and long term standing. Herein, we have observed how the liability amounts are computed and treated, for the fair view of financial health of Myer. Last, but not the least, the concluding topic of discussion was the right relationship between measurement of liability and the useful decision making by business entities, so as to enhance the number of productive business decisions. The assignment proved helpful in attaining the knowledge of liabilities and decision-making. Reference AASB (2013, October 15). AASB Paper discusses accounting for liabilities.

Approaches in Lifelong Learning free essay sample

The need of the learners was identified as having to have investigators who could adopt a methodical approach, which is essential whilst carrying out equipment failure investigations. This was used as my session aim: ‘This learning session will teach you a methodical approach of investigating equipment failure’. When identifying the need for training I first assessed what the learners would have to have learnt by the end of the learning session. This was identified as the need to know what equipment would be used and how to carryout an investigation in easily managed phases. I then used this as my objective: By the end of this lesson you will have been introduced to the contents of the investigator pack and be able to identify the 3 phases of an equipment failure investigation’. (1. 2) The learners were identified as personnel with some previous learning within the subject matter.

Answers to Questions About Articles

Answers to Questions About Articles Answers to Questions About Articles Answers to Questions About Articles By Mark Nichol 1. I found the follow information about the indefinite article a in The Oxford Advanced Learner’s Dictionary: â€Å"used before uncountable nouns when these have an adjective in front of them, or phrase following them. For example, â€Å"a good knowledge of French†; â€Å"a sadness that won’t go away.† I dont understand the information. The dictionary says that the a is used before uncountable nouns when these have an adjective in front of them. But, as far as I know, the indefinite article a cannot be used in front of uncountable nouns. Does the information mean that we can always use the indefinite article a in front of uncountable nouns that have an adjective in front of them? Is it a rule? Mass, or noncount, nouns can be preceded by the indefinite article a when they are modified by a preceding adjective or a subsequent phrase: For example, though you would refer to bravery as courage, not â€Å"a courage,† you can write of â€Å"an uncommon courage† and â€Å"a courage like no other.† However, the passage from the resource you mentioned refers only to the possibility of the former type of usage, not to its ubiquity; it is rare. 2. Something I would like some clarification on is the use of a or an before the word holistic. I have been taught an, but this doesn’t seem to make sense to me, as there are many instances when a word beginning with h is preceded by a rather than an. Are you able to shed some light on this? Use a or an before a word that begins with the letter h depending on whether the h is pronounced: â€Å"a historic occasion,† but â€Å"an honest mistake.† 3. I don’t know what to do with the names of institutions when they call themselves a name with the in the title for example, â€Å"the Open Door.† In the middle of a sentence, do you have to capitalize the? Would you say, â€Å"We met at The Open Door†? The direct article should be lowercase even when it is integral to an entity’s name (as in â€Å"the American Automobile Association,† when it would not be referred to, minus the, as American Automobile Association†), but many entities insist on capitalizing it as part of a branding identity. (And it’s best to do so for indirect articles, as in, for example, the name of a community center called A Place for Teens.) If you work for the Open Door or it’s giving your organization money or other consideration and management at the Open Door wants the name treated as â€Å"The Open Door,† treat it as â€Å"The Open Door.† Otherwise, style it â€Å"the Open Door.† Want to improve your English in five minutes a day?

Rhetorical Devices Essay Example | Topics and Well Written Essays - 250 words

Rhetorical Devices - Essay Example This is a very complex and complicated matter. Now this  resolution will pass, although we all know that the President can wage a war even without it. However difficult this vote may be, some of us must urge the use of restraint. Our country is in a state of mourning. Some of us must say, lets step back for a moment. Lets just pause, just for a minute and think through the implications of our actions today, so that this does not spiral out of control. Now I have agonized over this vote. But I came to grips with it today, and I came to grips with opposing this resolution during the very painful, yet very beautiful memorial service. As a member of the clergy so eloquently said, "As we act, let us not become the evil that we deplore." The speech of Barbara Lee in the House of Representatives on September 14, 2001 was a speech concerning H. J. Res. 64, or the authorization for the use of military force against those responsible for the 9-11 terrorist attacks in the United States. It was obvious from the speech that she did not want to vote for the passing of the bill because of her moral stance against violence and vengeance. In her speech, she showed her opposition to the proposed military authorization using certain rhetorical devices. For her logos or the use of reason in order to achieve her goal of convincing her fellow representatives of the futility of the military authorization, she used the statement: â€Å"†¦I am convinced that military action will not prevent further acts of international terrorism against the United States. This is a very complex and complicated matter† (Lee, 2001). This rhetorical device is credible. It is actually meant to give a logical reason to the whole speech, specifically to why the speaker refuses the military authorization. The idea of terrorism is indeed more difficult and complicated than something that can just be quelled by

Evidence Based Practice - Vascular Bleeding Following PCI Essay

Evidence Based Practice - Vascular Bleeding Following PCI - Essay Example 3.0%), particularly hematoma (1.1% vs. 2.5%) and pseudoaneurysm (0.1% vs. 1.0%), as compared to MC use (n = 951). Odds ratio of developing complications for VCD recipients was 0.56 (95% CI: 0.40 – 0.79). Because baseline characteristics between treatment groups were initially different, statistical adjustment was done. In 2010, a prospective, small-scale, short-term case-series study involving 413 patients treated of acute coronary syndrome was used to identify predictors of vascular complications. The use of VCDs by the sample was fairly limited, only 62 used Angio-Seal and 19 had PerClose. For those who used VCDs, there were no significant differences in the occurrence of hematoma during or after the use of procedure. In addition, those with complications were old and had significantly higher systolic blood pressure, as compared to those that did not have complications (Sulzbach-Hoke, Ratcliffe, Kimmel, Kolansky, & Polomano, 2010). The different VCDs were also compared. In patients that have received PCI in the past eight years, those who underwent VCD (n = 2, 814) had significantly lower incidence rate of ≠¥ 10 cm hematoma as compared to those who were given MC (n = 1, 407), 1.1% vs. 2.1%. Baseline characteristics between VCD and MC groups were not statistically different. Comparison among Angio-Seal, Perclose and Starclose users revealed that those who used Perclose had the least rate of complications (5.6%), while those receiving Starclose had the most (10.2%). The differences among rates were significant (Iqtidar, Li, Mather, & McKay, 2011). A similar, wider scale, retrospective study (n = 1, 819, 611) was conducted 2012 by Tavris, et al. The rates of bleeding in Angio-Seal (28.7%), Perclose (8.3%), Boomerang Closure Wire (BCW) (0.6%) and hemostasis patches (7.9%) VCDs were less than 1%, while those receiving MC (38.9%) was 1.18%. In contrast, StarClose (4.4%) and Mynx

Critical Evaluation of HRM and Organisation Behaviour Theories Coursework - 2

Critical Evaluation of HRM and Organisation Behaviour Theories Frameworks - Coursework Example The paper explains that human resource management is a broad spectrum of professional mandate that has to do with anything that deals with the handling of people (human resource). As far as the people are concerned, human resource management caters for â€Å"compensation, hiring, performance management, organization development, safety, wellness, benefits, employee motivation, communication, administration, and training†. Human resource management has been given a theoretical framework by the Business Ball whereby it is related to the psychological contract. It is said that â€Å"The Psychological Contract' is an increasingly relevant aspect of workplace relationships and wider human behavior.† This means that human resource management is considered a necessary phenomenon not just because of the fact that it is needed to lead to the growth and development of an organization but then because it is needed to be in place to protect the basic relationship that needs to exis t between the human workforces in the organization.   This makes human resource management an aspect of organizational management that is needed to have a more permanent basis. It is in this regard that human resource management has always been discussed along with the lines of organizational behavior – because the organizational behavior has a more permanent stake in all organizations. Organizational Behavior has been explained as â€Å"the study and application of knowledge about how people, individuals, and groups act in organizations† (Clark, 1998). This means that organizational behavior can lead to a better comprehension of the type of human resource management that should be in place at a workplace or a given organization and this is the reason why the two concepts are always treated hand in hand. Assumptions underpinning the way in which HRM and organizational behavior theories and frameworks have been propagated Rank (2011) notes that human resource management and organizational behavior has existed with humankind since time immemorial. The only difference is that these two phenomena of management have been through a lot of changes and transitions. The good news is that handling of both human resource management and organizational behavior has been improving with time. There is indeed exists a chain of assumptions underpinning why and how theories and framework of human resource management and organizational behavior all came about. Rank (2011) attributes the conception of the two theories and framework to the emancipation of human rights such that the need to promote the well-being and welfare of all people - regardless of whether they are employees or employers was deemed necessary.  

The Purpose Of Punishment In The Justice System Criminology Essay

The Purpose Of Punishment In The Justice System Criminology Essay Case Study 2: The purpose of Punishment within the criminal justice system. What role does punishment serve within the criminal justice system? Consider the part played by reductivism, incapacitation, retribution, deterrence and rehabilitation as by-products of the perceived need for the criminal justice system to punish offenders. How have political policies and other ideologies affected the state emphasis on the need to punish offenders? In the following paragraphs it is going to be explained the role of punishment within the criminal justice system. Furthermore, we are going to get involved with theories and objectives related to punishment such as: reductivism, deterrence, rehabilitation, incapacitation and finally retribution. Beginning our case study we have to argue that there is considerable controversy over the effectiveness of punishment in reducing crime, but whether or not its actual effectiveness, still is the only method being used conforming someone who made a misdeed, back to society and freedom. Punishment can be simply defined as a legally approved method designed to facilitate the task of crime control (Carrabine, 2004), and its main purpose is to rehabilitate the offender, expiate the victim and dissuade others from becoming wrongdoers. In order to successfully create a holistic view on the matter, we have to focus on many punishment perspectives and theories as it is the only way for a critical evaluation. punishment as a social institution is an inherently complex business that needs to be approached from a range of theoretical perspectives as no single interpretation will grasp the diverse meanings generated by punishment (Carrabine, 2004). The reductive theory of punishment justifies that punishment occurs because it helps to prevent and reduce future consequences of crime, acting as a forward-looking theory for the general good. Moreover, claims that if punishment takes place, future crime will be less than if no penalty were inflicted. For punishment to reduce future crimes, the pain and unhappiness caused to the offender must be outweighed by the avoidance of unpleasantness to other people in the future (Cavadino, 2002). Therefore, it is a moral action against criminals (famously advanced by Jeremy Bentham 1748-1832) since it produces the greatest happiness of the greatest number of people. Nevertheless, there are many mechanisms of reduction which will be shown below. Deterrence based on utilitarian theories, is a method of reduction and its main perspective is that if you cause someones fear, then he will be afraid to offend and break the law (tough on crime). Moreover, separates deterrence into general and individual justifying that general is when punishment dissuades others from following the offenders example, in spite of individual deterrence which aims to teach delinquent not to repeat the behaviour. Deterrence lacks to produce strong and validate evident of its effectiveness as no certain penalty prevented someone from committing a given crime. What is more, referring to the individual deterrence, my opinion is that we cannot say whether or not an offender stopped his criminal behaviour, simply because not all crimes are being convicted. Also, according to official crime statistics, I believe, there is not such effectiveness as Michael Howards supported about prison/punishment and toughness on crime. Prison works. It ensures that we are protected from murderers, muggers and rapists- and it makes many who are tempted to commit crime think twice (Michael Howard, Home Secretary 1993). Rehabilitation is another mechanism of crime reduction which is going to be produced and evaluated on the following paragraphs. According to rehabilitation the idea of punishment is to apply treatment to the offender so that he is made capable afterwards to return back to the society as a law-abiding member. Rehabilitation is viewed as a humane alternative comparing to the harshness of retribution and deterrence giving more a programme function to the punishment, without that meaning that an offender would receive a more lenient penalty for his offence. An important feature of rehabilitation is that the offender could stay on probation whether that means outside prison or inside until he is thought to be ready. Critics though assume that if the prison administrator is the responsible one who decides if offender made a progress and he is ready to go, then corruption may occur which will falsify the true situation. Finally, another issue is that an offender guilty for minor crime proba bly could not tolerate lengthy detentions simple because of inability or refusal to adopt a subservient attitude toward prison officers and authority in general. Continuing our study we will refer to retributive theory which is in total antithesis of reductivism and justifies that punishment came as result of criminality. An attractive feature is that retributivism is a natural connection between the retributive approach and the idea that both offenders and victims have rights. Reductivist theory always founds it difficult to encompass the notion of rights, even when it comes to providing entirely innocent people with a right not to be punished. Retributivism has no such problem, since it follows automatically from the retributive principle that it must be wrong to punish non-offenders. Criminals, according to retributivist principle deserve the punishment because in some way, evil for evil somehow make a right. Additionally, according to retributivism, severity of a punishment should be proportionate to the gravity of the offence (tariff). What is more, retributive punishment, argues that applies fairly and equally to all of us as long as we all live in the same equilibrium followed by the same norms and values. The main issue with such a theory is that it would be objective only if we were all genuinely equal sharing the same advantages. Detected offenders typically start from a position of social disadvantage (Cavadino, 2002). From the moment retributive punishment tries to inflict equality restoring the balance, then increases inequality rather than do the opposite. The last theory refers to the act of making the offender not capable of committing a crime and is known as the incapacitation theory. According to that, offenders who have committed repeated crimes or thought to be dangerous are being punished by execution or lengthy incarceration (life imprisonment). Such a punishment though unfortunately makes it difficult to identify that kind of offenders. Thus, it is extremely controversial the principle of incapacitation especially to those who assist that punishment should advocate equal retribution followed by dignity. An important controversial example evaluating incapacitation is the chemical-castration of sex offenders (against children) with hormonal drugs which was first adopted in the U.S of California in 1996 and proved that drugs alone did not make the offender incapable of committing sex crimes. To conclude, I would like to say that I have not come to a conclusion yet on whether or not punishment actually helps and rehabilitates the delinquents. But I am sure that punishment so far is the function which separates those who live legally and those who do not. I also believe that the fear of punishment changes people behaviour a lot, as we all are afraid of punishment is that not true? Ultimately, I would like to finish with Sir Thomas Mores opinion which finds me totally agreed. Society first creates thieves, and then punishes them for stealing. There has always existed a curiously symbolic relationship between the criminal and society. It is not so much that society tolerates crime, rather the structure of modern society inevitably creates situations and circumstances in which crime occurs(Weisser, 1979).

A Worn Path, The Bean Trees, Little Women, How It Feels To Be Colored M

Courageous and Heroic Women in A Worn Path, The Bean Trees, Little Women, How It Feels To Be Colored Me, and the The Piano  Ã‚   Women have been heroic and courageous throughout history, though not all of these heroic (or courageous) adventures have been shown in any way.   Some of women’s heroic and courageous adventures are portrayed through short stories, books, and movies.   Eudora Welty’s short story â€Å"A Worn Path,† Barbara Kingsolver’s book The Bean Trees, Louisa May Alcott’s book Little Women, Zora Neale Hurston’s story â€Å"How It Feels To Be Colored Me,† and the movie â€Å"The Piano† all show women going through their own amazing and heroic adventures.   In these stories, the authors and director share with the reader (and watcher) the heroics of a woman.   Though these heroic adventures are full of risk and danger they are very valuable adventures for the characters’ health and development. In â€Å"A Worn Path† the character Phoenix Jackson walks through the forest on her way to town to get her grandson some medicine.   Now, Phoenix is an elderly lady, so this trip takes her awhile.   She has to go up and down hills, through thorny thickets, and over streams on logs.   Throughout the story she talks to herself and encourages herself to go on.   She talks to the brushes and the animals that she hears and tells them to keep â€Å"out of my way all you foxes, owls, beetles, jack rabbits, coons and wild animals!   Keep from under these feet†¦Ã¢â‚¬  (Gilbert and Gubar 1641). This trip shows how heroic Phoenix is, for it’s pretty risky for her to take.   It might not be as risky for a younger person, but it’s hard for an older woman to go through barbed-wire fences, over logs, and through ditches.   She could get caught or hurt on any of the obstacl... ...es where he gets to do more with her than she wants, like touching her, taking off some of her clothes, and eventually sleeping with her.     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   All of these women show their courage in some way or another, whether that courage is of the heart, mind, or body.   Women have had heroic and courageous qualities throughout history, but these women are some very good examples of how some women have the nerve and bravery to do and think what they feel is right no matter what men or other women think of them.   Works Cited: Alcott, Louisa May.

Endothelial tight junction proteins Essay

Endothelial tight junction proteins Introduction            The endothelium is situated at the inner side of all kinds of vessels and comprises of a monolayer of endothelial cells. Inter-endothelial junctions comprise junctional complexes, such as adherens junctions (AJ), tight junctions (TJ) and gap junctions (GJ) that play essential roles in tissue integrity, barrier function and intercellular communication respectively. These junctional complexes are related to those found at epithelial junctions with notable changes in terms of certain molecules and structure.            Endothelial junctional proteins play important roles in tissue integrity but also in vascular permeability, leukocyte extravasation and angiogenesis. Dormant endothelium may be exposed to stimuli provoking leukocyte extravasation at seditious sites and propagating angiogenesis. Both activities have an intense impact on endothelial cell-cell junctions.            Tight junctions aid the major functional objective of establishing a barrier inside the membrane, by controlling paracellular permeability and sustaining cell polarity. They achieve this by constricting apical or basolateral transmembrane diffusion of lipids and they have been suggested to contribute in regulating proliferation and differentiation of epithelial cells. However, the components that are involved and the signal routes concerned are unknown (Mitic & Anderson 1998).            Tight junctions are made up of integral membrane proteins claudins, occludin, tricellulin, junctional adhesion molecules (JAMs), including many peripheral membrane proteins such as the scaffold PDZ- domain proteins. This review will however, focus on ZO-1 and ZONAB. Histology of endothelia junctions            The junctional structures situated at the endothelial intercellular fissure are related to those located at the epithelium; however, their formation is more inconsistent and in most vascular beds their topology is less constrained than in epithelial cells. Adherens junctions, tight junctions and gap junctions are in most cases intermingled and create a complex zonular system with disparities in depth and thickness of the sub-membrane plate associated with the junctional structure (Franke et al. 1988; Rhodin 1974). In contrast to epithelial cells, GJs are often found close to the luminal surface. Hence, the term â€Å"Apical junction† used to jointly describe epithelial TJ and AJ may not be applied to the endothelium. The endothelium forms the vascular barrier with controlled permeability properties between the blood and the underlying tissues.            Tight junctions exhibit considerable inconsistency among different segments of the vascular tree (Franke et al. 1988). This disparity composes a major evidence of vascular bed differentiation of endothelial cells and has a strong impact on vascular permeability and leukocyte extravasation. Variations concern the complexity degree of the occluding strands as well as tight junction composition.            Large Artery endothelial cells, which are exposed to high flow rates, display a well-developed system of tight junctions. Within the microvasculature, tight junctions are less complex in capillaries than in arterioles, and even less in venules. It is important to mention that, post-capillary venules are the primary site of leukocyte extravasation, and accordingly, they display a high content of permeability mediator receptors, such as those for histamine, serotonin and bradykinin. On the other hand, blood brain barrier (BBB) and the blood retinal barrier (BRB) are predominantly rich in Tight Junctions and endothelial tight junctions have been principally studied in these sites.            Endothelial intercellular realms differ from those of epithelial cells by the absence of desmosomes (Franke et al. 1988). The transitional filaments, comprised in the endothelium by vimentin molecules, are poorly connected to cell-cell contacts. However, contrary to the situation in epithelia, the vimentin filaments may be associated to endothelial adherens junctions in junctional structures similar to desmosomes, called complexus adherens.            It must be emphasized that interendothelial junctions are vibrant structures, subjected to multiple regulations. Moreover, leukocytes extravasate majorly in postcapillary venules either through transcellular or paracellular methods. Extravasation via the intercellular junction is a rapid and controlled process, through which the leukocyte is squeezed in the fissure (diapedesis), followed by rapid junction reformation.            ZO-1 is a protein located on the cytoplasmic membrane plate of intercellular tight junctions and is engaged in transducing signals at cell-to-cell junctions. ZO-1 links tight junction transmembrane proteins to a cytoplasmic plaque and the actin-based cytoskeleton (Aijaz et al. 2006; Tsukita et al. 2001). In epithelial cells, ZO-1 interrelates with the transcription factor ZONAB to regulate cells proliferation in a cell density related manner (Balda & Matter 2000); however, the functions of ZO-1 and ZONAB in endothelial cells are still not clearly understood.            Unpublished work shows that downregulation of ZO-1 in endothelial cells stimulates redistribution of two transmembrane proteins; claudin-5 and JAM-A, and radical changes in the cytoskeleton affecting the localization of mechanosensor proteins and VE-cadherin role in the control of cell-cell tension.            These observations imply that one function of ZO-1 in endothelial cells is to coordinate components of the tight junction and associate them to the cortical cytoskeleton. However, it is unfamiliar whether the ZO-1 associated transcription factor ZONAB is linked to such ZO-1 effects.            Despite the fact that, ZO-1 explicitly associates with epithelial tight junctions (Stevenson et al. 1986), it has been observed that the protein appears in the nucleus in the process of proliferation (Gottardi et al. 1996). While the functional impact of the nuclear localization is currently not clear, studies reveal that these discrete subcellular distributions of ZO-1 are exquisitely sensitive to the state of cell-to-cell contact.            ZO-1 plays a major role of restraining ZONAB and regulates its accumulation in the nucleus through cytoplasmic sequestration. MDCK cells found in the epithelium exhibit two forms of this Y-box transcription factor (ZONAB) i.e. ZONAB -A and ZONAB -B which vary in a 68-amino acid supplement. Both categories of ZONAB bind to ZO-1 and link with intercellular junctions (Balda & Matter 2000).            ZONAB was initially designated in canine kidney epithelial cells (MDCK) and is a Y-box transcription factor. Y-box transcription factors are multipurpose control mechanisms of gene expression and studies suggest that they play a common role in enhancing proliferation (Bargou et al. 1997). ZONAB is one of the tight junction-associated dual localization protein: it localizes to junctions where it attaches to the SH3 surface of the adaptor protein ZO-1, and to the nucleus where it regulates transcription.            The distribution of ZONAB is controlled by the cell density as it localizes to both junctions and nuclei in low density, proliferating cells, and becomes constrained to the cytoplasm in high density cells (Balda & Matter, 2000). This distribution is also exhibited in its transcription activity, as ZONAB is transcriptionally vigorous in proliferating cells but inactive in non-proliferating cells. In the MDCK cells, ZONAB is necessary for normal rates of proliferation and controls G1/S phase transition (Balda et al. 2003).            ZONAB affects cell cycle development by two distinct processes: it controls the nuclear accumulation of CDK4 through a direct interaction and controls manifestation of genes encoding cell cycle regulators for example, PCNA and cyclin D1 (Balda et al. 2003; Sourisseau et al. 2006 ).            In 3D principles of MDCK cells, regular ZO-1 and ZONAB processes are necessary for epithelial cyst formation, implying that the Y-box transcription factor also controls epithelial differentiation (Sourisseau et al. 2006). Since ZO-1 and ZONAB can also relate with other types of intercellular junctions, for instance the gap junctions, in cells that lack tight junctions, it is possible that ZO-1 or ZONAB signaling is also of useful significance in other cell types other than epithelia (Ciolofan et al. 2006; Giepmans & Moolenaar 1998). Aims of the study            The aim of the study is to understand the functional consequences of downregulation of ZONAB in endothelial cells, and whether and how ZONAB cross-talks with other junctional components to regulate endothelial cell migration, proliferation and angiogenesis. Currently, we are looking at similarities and differences between the phenotype of downregulation of ZO-1 or ZONAB by RNA interference. Changes in expression and localization of a given protein are analysed using specific antibodies for immunoblots and immunofluorescence. Preliminary Results            It is observed that downregulation of ZO-1 or ZONAB resulted in similar redistribution of actin and vinculin from cell-cell junctions to stress fibers and focal adhesions, respectively. However, the localization of transmembrane proteins such as Claudin-5 and JAM-A is affected by downregulation of ZO-1 rather than by downregulation of ZONAB. The localization of the polarity protein PAR-3 is changed in both conditions.            Additionally, downregulation of ZONAB causes changes in ZO-1 by immunofluorescence that needs to be tested for expression by immunoblots. Next, we will characterize other transmembrane proteins (e.g. MD3 and claudin-1), polarity proteins (PKCzeta), Rho regulators and mechanotransducers such as PAK2, Zyxin and YAP.            ZONAB is a DNA and RNA binding factor that it is involved in transcription (e.g. cyclin D1 and PCNA) in the nucleus and translation (e.g. cell cycle inhibitor p21) in the cytosol. Thus, we are also trying to identify new genes regulated. We have identified that expression of fibronectin is regulated by ZONAB. We are evaluating whether the changes in protein expression of fibronectin are due to ZONAB role on transcription or translation, using actinomicin D to inhibit transcription or cyclohexidimide to inhibit translation. Additionally, we are validating new genes identified by cDNA array analysis of endothelial cells with downregulation of ZONAB.            The tight junction localizing protein ZO-1 symptomatically forms a continuous band around the apices of well-differentiated, confluent, polarized epithelial cells in culture. However, under nonconfluent conditions, endogenous ZO-1 can localize to the nucleus in addition to the border of cell-cell contact.            ZONAB manifestation tends to be high in proliferating but low in growth-impeded MDCK cells, implying that high manifestation levels might be a necessity for cell proliferation (Balda & Matter 2000).            ZONAB confines in the nucleus as well as tight junctions in proliferating cells, however, it is not noticeable in the nucleus of nonproliferating high density cells (Balda & Matter 2000), proposing that accumulation of ZONAB in the nucleus might be necessary for efficient proliferation.            ZO-1 quantities are low in proliferating cells and they rise with cell density, and overexpression of ZO-1 hinders accumulation of ZONAB in the nucleus (Balda & Matter 2000); hence, ZO-1 may control proliferation by inhibiting ZONAB from accumulating in the nucleus. Overexpression of ZO-1 in low density cells triggers a redistribution of ZONAB from the nucleus to the cytoplasm and reduced proliferation.            CDK4 is a major regulator of G1/s transition (Sherr 2000; Malumbres & Barbacid 2001). Thus, ZONAB could control proliferation by regulating the process or the localization of CDK4. Since ZONAB binds CDK4, the nuclear pools of the two proteins may diminish in a parallel manner.            Symplekin is combined with ZONAB in the nucleus; hence, it could be argued that Symplekin modulates the transcription activity of ZONAB. Increased expression of Symplekin results in stimulation of the transcriptional suppressor ZONAB. However, it is also noted that Symplekin is absent in endothelial cells (Keon et al. 1996).            ZONAB controls cell cycle entry. ZO-1 overexpression results in a reduction in DNA synthesis, implying that entry into S-phase was distressed.            These experiments will allow understanding the role of ZO-1 and ZONAB in endothelial cells. Depending on the results, we plan to test how these two proteins are involved in endothelial stress conditions such as shear stress and high glucose. Conclusion            The collaboration of ZO-1 with tight junctions can only be significant for the stabilization of ZO-1, as opposed to attaching ZO-1 to the plasma membrane so as to constrain nuclear accumulation of related proteins. This is supported by the opinion that a truncated protein comprising only the HA-tagged SH3 domain accumulated in the Cytosol, but was adequate to decrease proliferation and nuclear accumulation of ZONAB (unpublished data).            ZONAB and ZO-1 control proliferation and the ultimate cell density of MDCK cells. Explanations that ZO-1 accumulates with increasing cell density, and overexpression of ZO-1 in transfected cells lowers the final density proposes a pattern in which ZO-1 serves as a measure for cell density whereby, on reaching the threshold level, provokes growth impediment by cytoplasmic sequestration of ZONAB and the related cell cycle kinase CDK4. It will be essential to control how the ZO-1 or ZONAB pathway associates with the other signaling methods that affect proliferation.            Vascular endothelial stress induces dysfunctions that have been implicated in many diseases such as diabetes and diabetic retinopathy. Therefore, characterization of the role of tight junction molecules in different endothelial cell behavior and functions will help us to understand the molecular mechanisms of disease pathogenesis and these findings may be implicated in prognosis and possibly to develop new treatment strategies.

Main Causes of Pollution in Urban and Rural Areas Essay Example

Main Causes of Pollution in Urban and Rural Areas Essay Example Main Causes of Pollution in Urban and Rural Areas Paper Main Causes of Pollution in Urban and Rural Areas Paper Over time, land pollution degrades the quality of not only the land in n area where waste is present, but also the quality of things growing in that land. Land pollution contaminates ground water, kills animal and plant species, causes disease and more. One of the major causes of land pollution is industrialization. Mechanized creation of goods sacrifices resource conservation in favor of speedy and inexpensive production. This results in a greater amount of industrial waste which must be disposed of. When it is not disposed of correctly it becomes surface waste and creates land pollution. Another cause of land pollution is chemical treatment of the land. Organic farming is the exception not the rule. Most farmers use harsh chemicals to fertilize their crops, eliminate weeds, kill of pests who pose a threat to the crop and more. The excess chemicals leave waste residue in the land and pollute it-Waste from human activity is, however, the most common cause of pollution. Waste causing pollution is caused by careless disposal of things that are thrown away including littering, and failure to recycle. Many teems go into a landfill which could be recycled and reused to both limit the amount of natural resources used to create synthetic products and reduce the amount of waste in land fills and private dumps creating land pollution. Land pollution is serious because it contributes to other forms of contamination including water and air pollution, as particles from the land pollution work into the water cycle. Limiting or eliminating land pollution improves every aspect of global conservation, and pollution management. This prevents potentially dangerous materials from negatively impacting the global quality of life.

ESSAY To what extent has the nature of power in Western liberal

To what extent has the nature of power in Western liberal democratic states changed in recent decades In your answer, ex - Essay Example Modern democracy can be dated from the late 18th century although medieval Poland and some states of the Greek cities had democratic aspects. Democracy as the rule by people. In order for a country to be considered democratic, it should choose its leaders using competitive and fair elections. It should adhere to the constitution and ensure fundamental civil liberties. While some analysts assert that a democracy needs to have a strong civil society, civic culture, and capitalist economy, others do not include these criteria when defining democracy. Democratization is therefore the process by which a country adopts such a regime as defined above. This means that when a country is democratized, it is democratic. It also means that every other person is entitled to his or her opinion regarding matters that concern governance. Unlike dictatorial regimes where one voice speaks and others follow, in democratic regimes it is the voices of the majority rule. This means that in case of electio ns or matters that bring disagreement, every person is given an opportunity to stand by what he or she thinks is the right option. As stated above democratization is a relatively recent practice. In the early days, monarchs ruled nations. These were kings and queens and in some cases, the church. The king’s word was final. ... There however seems to be little agreement among political analysts regarding how the process of democratization occurs, including the criteria used to ascertain if democratization has indeed occurred. Many countries adopt democratic governments only to watch them collapse through military coups and other revolts that lead to authoritarian regimes. The first pointer is that citizens should be able to govern themselves by conducting regular elections, which determine their top leaders periodically. This is referred to as representative democracy. These regular elections also serve as avenues through which policies that govern the people are chosen. An example is the voting process which determines if a constitution is to be passed or not through a referendum. Secondly, the right to vote is accorded to all adults. This however has been a recent addition since governments that were referred to as democratic not so long ago used to exclude women, slaves, and free males who did not meet c ertain literacy or property requirements. If a country restricts this franchise from the voting process, then it cannot be considered as democratic. A perfect example is the apartheid regime in South Africa whereby the only people who voted were minority whites. The third indicator is the acceptance of democratic rights. These particular rights include the right to contest for the highest office, the right to have everyone’s vote count equally, the right to vote and the right to create and form political parties and groups. Then there is a law, which is above the state. All authorities on the particular country should adhere to this law. It provides the framework for democratic rule and protects the democratic rights of the people. Therefore,

Toyota Essay Example | Topics and Well Written Essays - 750 words

Toyota - Essay Example This paper seeks to explain and illustrate the Toyota’s corporate responsibility to its consumers, environment, employees, stakeholders, and to the general public. This will be done through looking into the company’s corporate responsibility page and showing examples of how this company helps others. According to the Toyota’s corporate responsibility page, the company embraces corporate social responsibility initiatives; this includes information regarding policies, people and organizations that are related to the corporate social responsibility of Toyota Company. Toyota Company engages and promotes both with their partners and individually social contribution events and activities that aid in strengthening communities and contribute to supporting and enrichment of the society. In addition, Toyota embraces environmental responsibility. For example, everything from the basic stance of Toyota Company to its specific initiatives is put in place to make the environme nt better. In-depth annual environmental activities coverage is part of Toyota’s social and environmental initiatives. Toyota Company has been in support of SOS children villages’ mission to provide safe homes to thousands of children orphaned in the country. Toyota has also been a pivotal partner in the progressive development of the SOS children village from 2010 as a major part of the company’s corporate social responsibility program. Toyota Company has also made contributions to Mater Heart Run in 2012. This is the company’s fifth year in sponsoring a noble program aimed at helping children from poor families who are unable to afford the expenses of cardiac surgery. In other cases involving Toyota and its customers, the company’s public relations department helps the consumers to their satisfaction in case of crisis. Toyota also remains socially responsible and solves its customer related issues. For example, The Toyota’s public relation department has the mandate to handles customer complaints and grievances. When there was a Toyota Acceleration case crisis, Toyota tried to deny the existing problem and responded very slowly to the crisis. The Toyota Company had realized the problem much earlier but responded late. The public relations department of the distressed company could calm customers down neither. Toyota however never complied with the law and failed to notify the authorities of the technical problem. This led to the failure of Toyota failed in rectifying the manufacturing problem; thus, failed to restore its image as a customer safety oriented company (Rothaermel, 2013). Those held accountable for the crisis was the board for miscommunication and focusing on varying values and goals. The Japanese managers who failed to make quick decisions and confined information to them. However, after the crisis, Toyota initiated an effective way to manage the aftermath. It changed its motto and issued 4 letters to th e public apologizing for the problem within a span of one month. These effectively calm the customers down as they felt considered and understood. After the apology went through, Mr. Toyoda managed to resume the management of the company in order to show a refocus on the strategy and values of the company. Mr. Toyoda committed his personal time in his testimony to the United States House Committee on Oversight and Government reforms. The management of

Foundation of Leadership Essay Example for Free

Foundation of Leadership Essay How do leaders of today become what they are now? What experiences did they gone through in stabilizing their foundations of good and ideal leadership? There are just too many aspects in life that will mold you to become an efficient leader. Every experience, person you will meet, and their ideals will contribute to create a leader out of you. 1. Create a diagram that demonstrates the interplay of your life. Include the aspects that you think are important. The diagram shows how an individual gain his skills and knowledge through social interaction. Personal experiences teach an individual what to do and what he will become in the future. The relationship and interaction with the people around you mold and stabilize your character. The work and experience that you have or have been engaged in will create the kind of leader you are or can be after surpassing circumstances and pressures. Your goals and desires will determine how far you can go. 2. What principles surfaced to you from your readings of Synchronicity? To what extent have you practiced any or all of the disciplines in the context of your personal life? Synchronicity, a book written by Joseph Jaworski, also discussed about important insights in leadership. He presented the value of servant leadership; wherein in an organization an individual is after the group instead of one’s self interest. Servant leaders should know how to listen, empathize, be aware, heal himself and the members, conceptualize, foresee, persuade, commit, and build his community. Servant leaders should also know how to keep the harmonious relationship among members. From my own experience, I have proven that servant leadership works. A leader who values the group members and their opinion has too far to go in leading. Listening, empathy and awareness are very important. Moreover, respect is also being gained in return. You can also expand and develop ideas through brainstorming. Jaworski also discussed the importance of advance planning and conceptualizing. You will be able to estimate and assume future events and circumstances, enabling you to know what to do or avoid in the future. Learning from the past is also important, past experiences can be one’s pattern in decision-making. Leadership skills can be developed and improved through one’s knowledge and experiences. Different styles can be used depending on the situation for a more efficient results, only proper decision-making should be done wisely. To be knowledgeable and ideal leader, explore the world and learn more things in life. Be responsible. 3. Locate one or more websites and journals that explore leadership traits and styles, and discuss management and leadership. A group of researchers led by Kurt Lewin, conducted an experiment in order to study and identify specific types of leadership. In result, the group established three major types: the authoritarian leadership (autocratic), Participative (democratic), and delegative (laissez-faire). (Kendra Van Wagner) In authoritarian leadership, clear expectations of all the details is provided such as what, when, and where something should be done. Leaders decide independently with a little contribution from the rest of the group, or even nothing at all. In this type of leadership, less creativity in decision-making is being formed by the group. However, it is applicable in situations wherein there is minimal time for group discussion or when the leader is the most knowledgable and reliable member of the group. (Kendra Van Wagner) Participative leadership allows everyone to take part in the discussion and decision-making processes and is guided by the leader. The output of the work lead by democratic leaders is more creative. Members are being more motivated and creative as the leader encourage them to participate, but preserve the final decision to him. (Kendra Van Wagner) Members under delegative leadership work independently with a little or no guidance at all from the leader and leave decision-making to the rest of the group. On the other hand, this style can be useful for members that are highly competent in an area of proficiency, but frequently results into weakly defined roles and lack of enthusiasm. (Kendra Van Wagner) Leadership goes hand in hand with management. Though the two are inseparable terms, it is important to know the distinction between them. Leadership deals with the concept and rationale while management is into the logistic details such as who, when and when. Leaders direct the organizarion while managers handle the process towards a certain goal. Leaders motivate others to go beyond their limit and explore whereas managers make others do what they need to do. Managers are focused on present circumstances; leaders conentrate on conceptualizing and foreseeing. Leaders plan; managers make things done. They have different jobs and responsibillities, yet the two are directly linked to each other. How can you plan for the future and lead if you don’t know how to manage and work things out?

Analysis Of The Wheatstone Bridge

Analysis Of The Wheatstone Bridge This Term Paper is about topic Wheatstone Bridge. A Wheatstone bridge is a device which is used to find the unknown resisitance. It is an instrument or a circuit consisting of four resistors or their equivalent in series which is used to determine the value of an unknown resistance when the other three resistances are known. If talk in some little detail then wheatstone bridge contains the four resistance in which one is unkown resistance which we have to find ,one is variable resistance which is also called the rheostat of the circuit and two known resistance. It also contains the galvanometer for the detection of the current and it is also use to find the direction of current. The various use of wheatstone bridge is as under:- It is is used by electrical power distributors to accurately locate breaks in a power line. It is also used to monitor sensor devices such as strain gauges. Such devices change their internal resistance according to the specific level of strain (or pressure, temperature, etc.), and serve as the unknown resistor RX. Meter bridge, post office box and Carey Foster bridge are instruments based on the principle of Wheatstone bridge The basic use is to measure the unknown resistance. What is a wheatstone bridge? The wheatstone bridge is an instrument which is generally used to measure electrical resistance by balancing a bridge circuit. The bridge circuit contains four resistance, one of which contains the unknown resistance ,one variable resistance and two known resistance. Introductions to Wheatstone Bridge:- Wheatstone Bridge, a device for measuring electrical resistance. In wheat-stone bridge four resistance R1, R2, R3and R4are connected end to end with each other to form a closed loop. A sensitive galvanometer Gis connected between their junctions. One form of Wheatstone bridge is shown in the following example:- For example:- When the Wheatstone bridge is connected in an electrical circuit, part of the current flows to the object whose resistance is unknown and part of current flows to the resistor of known resistance. If more current flows through one side of the circuit than the other, the galvanometer shows the deflection. Due to potential difference create in between them when the current flows equally along both sides of the bridge then the galvanometer shows zero deflection. Thus the bridge is balanced, the unknown resistance is calculated by using formula. The formula is:- R1/R2=R3/R4 Where R1 is the unknown resistance. R2 is the variable resistance R3 and R4 are the known resistances Generally wheat-stone bridge is used to determine unknown resistances. Conditions for wheatstone bridge:- There are two conditions for wheatstone bridge which is as under:- Condition-1:Galvanometer is always in zero potential in the circuit. Condition-2:We should have to take one variable resistance. History of Wheatstone bridge:- [link 1] Wheatstones bridge circuit diagram. A Wheatstone bridgeis an electrical circuit invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. It is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of bridge contains the unknown component and variable component. Its operation is similar to the originalpotentiometer. Potentiometer :- [link 2] A potentiometeris an instrument for measuring the potential (voltage) in a circuit,they were used in measuring voltage. Creation of Wheatstone bridge by different scientists:- [link 5] 1) A scientist and mathematician, Samuel Hunter Christie, developed the circuit to measure unknown electrical resistances and first described it in 1833. The bridge worked because of the special diamond-shaped arrangement of the four resistors. Electrical current from a battery split into two parallel branches of the circuit. One consisted of a resistor with a fixed, known resistance and an adjustable resistor, also with a known resistance. The other leg contained a resistor of fixed and known resistance and another whose resistance needed to be determined. By using a galvanometer to balance the current flowing through the two branches, Christie could, with the help of a little math, determine the value of the unknown resistor. 2) Then another British scientist, Wheatstone, came across Christies description of the instrument, which Wheatstone referred to as a differential resistance measurer. A prominent member of the Royal Society of London, Wheatstone was well-positioned to give the tool a popularity boost. He gave an account of Christies invention at an 1843 lecture, and soon after it came to be called the Wheatstone bridge was used in telegraphy and other applications. Wheatstone himself, however, gave full credit for its invention to Christie. But in translations of his lecture that appeared in Germany and France the following year, Wheatstones attribution was nowhere to be found. In addition to bringing the device to public attention, Wheatstone improved the design (Wheatstone developed the rheostat, a variable resistor) and found several new uses for it. By changing the type of elements contained in its legs, the Wheatstone bridge can determine unknown capacitances, inductances, frequencies and other properties. Besides Wheatstone, several other scientists helped extend the range of the device, including William Thomson, Lord Kelvin and James Clerk Maxwell. This sensitive, accurate method for measuring resistance is still widely used today. Theory of Wheatstone Bridge:- To understand this circuit, consider the following Figure to be two voltage dividers shown below: When the bridge is balanced, the voltages measured by V1and V2are equal, hence no current flows through the Galvanometer G in above figure. Since V1and V2are at the same voltage, the resistance ratios Rx/RSand l1/l2are equal. Because the slide wire has a uniform resistance per unit length, the length ratios l1/l2is equivalent to resistance ratio R1/R2. How Equipment of wheatstone bridge works:- [Link 8] The current flows from positive to negative through the circuit.When it reaches Point Ain the diagram, it splits and travels through either one of two Known Resistors, R1 or R2. Resistance is measured in a unit called an ohm. Here we notice that when this applet initializes, the resistance at R1 is 1 K ohm, while at R2 it is also at 1 K ohm. After the diverging currents pass through their respective resistors (R1 or R2), each reaches another fork in the road. At this point, if the bridge is not balanced, some or all of the current from either the R1 or R2 path will diverge down this middle path that bisects the square created by the circuit. The Galvanometer ispositioned on this middle path which generally tells the presence or absence of current.The direction of this current is determined by the value of the Variable Resistor(R3). Here at this time the bridge is not balanced because the ratio of resistance on the known leg (R1/R2) is not equal to the ratio on the unknown leg (R3/R4). This is where the variable resistor which is also called rheostat of the bridge comes into play. It can be adjusted until no current flows down the middle path. When that is achieved, the Galvanometer reads zero and the bridge is balanced. Achieve this balanced state by adjusting the Variable Resistorslider until the Galvanometer reads zero and no more current flows through the middle path. Notice how the arrows depicting current direction change as you manipulate the slider. The ohm value is displayed above the slider. By discovering the value of the variable resistor in the balanced bridge, you are able to determine what the unknown resistance at R4 is, with a little math: R1/R2 = R3/R4 or R4 = (R2 * R3) /R1 So by using the above formula we can easily find out the unknown electrical resistance. Derivations:- Derivation of Wheatstone Bridge:-[link 1] First, Kirchhoffs first rule is used to find the currents in junctions Band D: When then I3= Ixand I1= I2(3) Then, Kirchhoffs second rule is used for finding the voltage in the loops ABDand BCD: The bridge is balanced when Ig= 0, so the second set of equations can be rewritten as: .(1) .(2) By dividing equation 1 by 2 we get:- From the equation (3), I3= Ixand I1= I2. The desired value of Rxis now known to be given as: If all four resistor values and the supply voltage (VS) are known, the voltage across the bridge (VG) can be found by working out the voltage from each potential divider and subtracting one from the other. The equation for this is: This can be simplified to: With node B being (VG) positive, and node D being (VG) negative. Bridgeconatianing constant voltage and voltage gage :- A basic Wheatstone bridge circuit contains four resistances, a constant voltage input, and a voltage gage, as illustrated below. For a given voltage input Vin, the currents flowing through ABCand ADCdepend on the resistances, i.e., The voltage drops from Ato Band from Ato Dare given by, The voltage gage reading Vgcan then be obtained from, Now suppose that all resistances can change during the measurement. The corresponding change in voltage reading will be, If the bridge is initially balanced, the initial voltage reading Vgshould be zero. This yields the following relationship between the four resistances, We can use this result to simplify the previous equation that includes the changes in the resistances. Doing so results in the solution for the change in Vg, where h is defined by, Moreover, when the resistance changes are small ( which is the basic equation governing the Wheatstone bridge voltage in strain measurement. The coefficient is called the circuit efficiency. Equal-Resistance Wheatstone Bridge Circuit:- In practice, one often uses the same resistance value for all four resistors, R1= R2= R3= R4= R. Noting that r = 1 in this case, the change in voltage can be further simplified to, By thoughtfully selecting the target and reference resistances, the Wheatstone bridge circuit can amplify small changes in resistance and/or compensate for changes in temperature. How to use the Wheatstone Bridge :- In its basic application, a dc voltage (E) is applied to the Wheatstone Bridge, and a galvanometer (G) is used to monitor the balance condition. The values of R1 and R3 are precisely known, but do not have to be identical. R2 is a calibrated variable resistance, whose current value may be read from a dial or scale. An unknown resistor, RX, is connected as the fourth side of the circuit, and power is applied. R2 is adjusted until the galvanometer, G, reads zero current. At this point, RX = R2ÃÆ'-R3/R1. This circuit is most sensitive when all four resistors have similar resistance values. However, the circuit works quite well in any event. If R2 can be varied over a 10:1 resistance range and R1 is of a similar value, we can switch decade values of R3 into and out of the circuit according to the range of value we expect from RX. Using this method, we can accurately measure any value of RX by moving one multiple-position switch and adjusting one precision potentiometer. Significance of wheatstone bridge :- [link 1] The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate. Variations on the Wheatstone bridge can be used to measure capacitance, inductance, impedance and other quantities, such as the amount of combustible gases in a sample, with an explosimeter. The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low resistances. In many cases, the significance of measuring the unknown resistance is related to measuring the impact of some physical phenomenon such as force, temperature, pressure, etc which thereby allows the use of Wheatstone bridge in measuring those elements indirectly. Applications of Wheatstone Bridge:- [Link 6],[Link 7] A number of resistance measuring devices have been devised on the principle of wheatstone bridge.For example : 1) Meter bridge, post office box and Carey Foster bridge are instruments based on the principle of Wheatstone bridge and are used to measure unknown resistance. 2) A very common application in industry today is to monitor sensor devices such as strain gauges. Such devices change their internal resistance according to the specific level of strain (or pressure, temperature, etc.), and serve as the unknown resistor RX. However, instead of trying to constantly adjust R2 to balance the circuit, the galvanometer is replaced by a circuit that can be calibrated to record the degree of imbalance in the bridge as the value of strain or other condition being applied to the sensor. 3) A third application is used by electrical power distributors to accurately locate breaks in a power line. The method is fast and accurate, and does not require a large number of field technicians. Other applications abound in electronic circuits. Well see a number of them in action as these pages continue to expand. Bridge circuits are widely used for the measurement of resistance, capacitance, and inductance. The resistive bridge, also known as Wheatstone bridge.
