legal process Essay In law, the Golden rule, or British rule, is a form of statutory construction traditionally applied by English courts. The other two are the â€Å"plain meaning rule† (also known as the â€Å"literal rule†) and the â€Å"mischief rule.† The golden rule allows a judge to depart from a words normal meaning in order to avoid an absurd result1. The term â€Å"golden rule† seems to have originated in the 1854 case of Mattison v. Hart as per Chief Justice Jervis’ propounding and implies a degree of enthusiasm for this particular rule of construction over alternative rules that has not been shared by all subsequent judges. For example, Viscount Simon made a point of including this note in a 1940 decision: â€Å"The golden rule is that the words of a statute must prima facie be given their ordinary meaning2.† Like the plain meaning rule, the golden rule gives the words of a statute their plain, ordinary meaning. However, when this may lead to an irrational result that is unlikely to be the legislatures intention, the golden rule dictates that a judge can depart from this meaning. In the case of homographs, where a word can have more than one meaning, the judge can choose the preferred meaning; if the word only has one meaning, but applying this would lead to a bad decision, the judge can apply a completely different meaning. History and evolution of the Golden Rule This rule is founded on Justice Parke (later Lord Wensleydale)’s enunciation in Becke v Smith where he stated thus: â€Å"It is a very useful rule in the construction of a statute to adhere to the ordinary meaning of the words used, and to the grammatical construction, unless that is at variance with the intention of the legislature to be collected from the Nokes v. Doncaster Amalgamated Collieries3, or leads to any manifest absurdity or repugnance, in which case the language may be varied or modified so as to avoid such inconvenience but no further.† Twenty years later, Lord Wensleydale restated the rule in different words in Grey v Pearson75 thus: â€Å"In construing statutes, and all written instruments, the grammatical and ordinary sense of the words is to be adhered to, unless  that would lead to some absurdity or inconsistency with the rest of the instrument, in which case the grammatical and ordinary sense of the words may be modified, so as to avoid that absurdity or inconsistency, but not farther.† With time, the rule continues to become more refined and therefore to be a more precise and effective tool for the courts. More than a century after Grey v. Pearson, a court added this caveat: â€Å"Nowadays we should add to natural and ordinary meaning the words in their context and according to the appropriate linguistic register.† In summary, this rule may be used in two ways. It is applied most frequently in a narrow sense where there is some ambiguity or absurdity in the words themselves. For Lord Simon of Glaisdale, reasons for judgment in Stock v. Frank Jones (Tipton) Ltd4 at 235 examples, imagine there may be a sign saying â€Å"Do not use lifts in case of fire.† Under the literal interpretation of this sign, people must never use the lifts, in case there is a fire. However, this would be an absurd result, as the intention of the person who made the sign is obviously to prevent people from using the lifts only if there is currently a fire nearby. The second use of the golden rule is in a wider sense, to avoid a result that is obnoxious to principles of public policy, even where words have only one meaning. The rule was applied in this second sense in Sigsworth, Re, Bedford v Bedford where the court applied the rule to section 46 of the Administration of Estates Act 1925. This statute required that the court should â€Å"issue† someones inheritance in certain circumstances5. The court held that no one should profit from a crime, and so used the golden rule to prevent an undesirable result, even though there was only one meaning of the word â€Å"issue.† A son murdered his mother and then committed suicide. The courts were required to rule on whom then inherited the estate: the mothers family, or the sons descendants. There was never a question of the son profiting from his crime, but as the outcome would have been binding on lower courts in the future, the court found in favour of the mothers family6. The Golden Rule The rule was defined by Lord Wensleydale in the Grey v Pearson case (1857) as: â€Å"The grammatical and ordinary sense of the words is to be adhered to unless that would lead to some absurdity or some repugnance or inconsistency with the rest of the instrument in which case the grammatical and ordinary  sense of the words may be modified so as to avoid the absurdity and inconsistency, but no farther.† So, The Golden Rule is a modification of The Literal Rule to be used to avoid an absurd outcome. The Golden Rule was used in the R v Allen case (1872). In this the defendant was charged with bigamy (s.57 of offences against the person act 1861) which, under statutes states: whosoever being married shall marry any other person during the lifetime of the former husband or wife is guilty of an offence. Under The Literal Rule, bigamy would be impossible because civil courts do not recognize second marriages, so The Golden Rule was applied to determine that the word ‘marry’ should be seen as ‘to go through ceremony’ and the conviction was upheld. The Golden Rule was applied in the Adler v George case (1964). Under section 3 of the official secrets act (1920) it was an offence to obstruct HM Forces in the vicinity of a prohibited area. Adler was arrested for obstructing forces whilst in a prohibited area. Under The Literal Rule, Adler was not in the VICINITY of the area – he was IN the area – and so was not infringing the terms of the act. The Golden Rule was applied to extend the meaning of ‘vicinity’ and avoid the possible absurd outcome. The main advantage of The Golden Rule is that drafting errors in statutes can be corrected immediately. This is seen in the R v Allen (1872) case where the loopholes were closed, the decision was in line with parliament’s intentions and it gave a more just outcome. A major disadvantage of The Golden Rule is that judges can technically change the law by changing the meaning of words in statutes. They can, potentially infringing the separation of powers between legal and legislature. The Golden Rule won’t help if there is no absurdity in the statute. For example the London and North Eastern Railway v Berriman (1946) case, where the widow couldn’t get compensation because the wording of the statute didn’t allow for this circumstance. The ‘Golden Rule’ as introduced by Lord Wensleydale in Grey v Pearson but perhaps better expressed by Lord Blackburn in River Wear Commissioners v Adamson We are to take the whole statute and construe it all together, giving the words their ordinary signification, unless when so applied they produce an inconsistency, or an absurdity or inconvenience so great as to convince the Court that the intention could not have been to use them in their ordinary signification†¦. In R v Allen and the Offence Against the Persons Act (1872), a case of bigamy, it was held that bigamy meant to take part in the  ceremony of marriage a whilst still married to another person, the statute could be applied successfully thanks to the application of the ‘Golden Rule’. Another example would be that found in Re: Sigsworth and the Administration of Estates Act 1925. The golden rule only rescues the court in tiny number of instances. The point was made by John Willis in a famous article where he asked â€Å"What is absurdity?† Absurdity is as vague as plain meaning. It is a matter of personal opinion, more susceptible to the influence of personal prejudice. Golden rule is just a device to achieve desired result and to escape from sum of the more updatable effect of literal rule (Nothman v. Barnet London Borough Council). The Law Commission criticised that there is no clear means to test the existence of the characteristics of absurdity, inconsistency, or to measure their quality or extent. This became known as Lord Wensleydales golden rule. It only applies where the words are ambiguous. An interpretation that is not absurd is to be preferred to one that is. An example is: R v Allen7 The Law Commission (1969) noted that: * The rule provided no clear means to test the existence of the characteristics of absurdity, inconsistency or inconvenience, or to measure their quality or extent. * As it seemed that absurdity was in practice judged by reference to whether a particular interpretation was irreconcilable with the general policy of the legislature the golden rule turns out to be a less explicit form of the mischief rule.

Management style to fit employee needs

Management style to fit employee needs Examine the argument that managers need to be able to adapt their management style to fit the needs of the employees. Your essay must include a minimum of six citations and two examples from different texts to support your arguments. No late, or partial, submissions will be accepted. There are several people said that managers need to change their style to be able to deal with different situation, but some people are not. Changing management style can help managers gain numerous of advantages such as to be more successful, be able to communicate more effectively with employees to understand what the employees are expecting from their manager. The purpose of this essay is to examine whether managers need to change their management style to fit the needs of the employees. This essay is divided into two sections which are the first is counter arguments that purpose managers do not need to change their style and the second is arguments that managers should change their style to fit the needs of the employees. This essay will argue that management style change depends on situation, people can change it, and they are not fixed. It can be argued that managers do not need to change their management style to be competent to deal with any situations and to be able to fit the needs of the employees, due to some reasons. First of all there are some structures and circumstances that have to maintain one style of management to work more effectively such as military structure or urgent circumstances. Indeed, in the military and other urgent circumstances, people tend to be told what to do next rather than wasting time on asking for some ideas (Shah, 2010). For instance, there is a terrorist attack at some place or soldiers have to rescue victims from there, it will take time and the mission may fail if a leader is democratic and ask so many people to give solutions (Kartha, 2011). In addition, employees may prefer a leader makes a decision and tell them what to do than having a discussion, when time is stressful. To be reducing stressful some employees are willing to become children and follow exactly what autocrati c leaders said (Cloke and Goldsmith, 2002 cited in J. Mullins, 2007). Another reason why managers do not need to change their style is contingency theory. Contingency theory argues that organizations should not expect that their leaders are able to lead in every situation; companies should place their leaders in situations that are ideal with their leadership style (Northouse, 2010). Thus, it can be seen that if leaders are in the wrong situations, organization should move the leader to another context that leaders are able to solve. Furthermore, Fiedler (1967 cited in Robbins, Bergman, Stagg and Coulter, 2008) stated that there are only two ways to improve leader successful that are change the situation to fit the leader and change the leader to fit the situation. Hence, managers do not have to change their style when they have to deal with different situations. According to contingency if a leader cannot deal with a group situation, company should change a leader who is competent to solve that task. For instance, if the group was rated as highly unfa vorable but was led by a relationship-oriented leader, the group should replace that person with a task-oriented leader (Robbins, Bergman, Stagg and Coulter, 2008). On the other hand, there are also some reasons that recommend managers should change their style to fit the needs of the employees. Firstly, managers should change their style when they move from a culture to another. It can be seen that each organizational has different culture, so managers cannot use the same management style to all the culture. Indeed, organizations are different, face different situations and require different ways of managing (Robbins, Bergman, Stagg and Coulter, 2008). In addition, the contingency approach said that in multicultural organizations, leader should understand that there is no one best way of communicating, effective communication is depends on the situation. Effective communication is the precondition to leaders understands their employees and knows what employees are expecting. For instance, during a crisis manager may prefer to tell subordinates exactly what to do to avoid discussion; however, discussion between the manager and employees might be accepted if time is more tranquil (E. Hynes, 2011). E. Hynes (2011) also claimed that different cultures possess different work values and communication styles. Therefore, managers must adjust their style to be able to communicate with employees of all culture to fit the needs of their employees. Moreover, national culture is an important factor that might help recognize which leadership style will be most effective (Robbins, Bergman, Stagg and Coulter, 2008). Successful leader do not use a style to all situation. They adjust their style depend on the situation to work more successful. For instance, works in China might not be effective in Australia or France (Robbins, Bergman, Stagg and Coulter, 2008). Hersey (1988) argued that successful leadership is achieved by selecting the right leadership style, which is contingent on the level of the followers readiness. In this case, followers readiness as defined by Hersey is people who are competent and confidence to accomplish a specific work (Robbins, Bergman, Stagg and Coulter, 2008). Hersey invented four leadership styles that are telling, selling, participating and delegating to match with four kind of readiness that are unable and unwilling, unable but willing, able but willing and able and willing. According to situation leadership model managers should adjust their style base on followers readiness to become more successful leader. In the same line of argument Mullins (2007) argued that managers should help subordinates to develop in readiness by adjusting leadership styles through the four styles of telling, selling, participating and delegating. For instance, if followers are unable and unwilling to do a task, leaders need to c hange their style into telling style; if employees are able and willing, leaders can change their style into delegating style (Hersey, 1988 cited in Robbins, Bergman, Stagg and Coulter, 2008). Contingency theory seems to be recommending that managers do not need to change their style to be able to fit the needs of the employees. Contingency theory stresses that managers are not effective in all situation. Hence, there are two ways to improve leaders successful that organization should change a leader to fit the situation by another leader who is able to solve it, and organization also can change the situation to fit a leader by restructuring tasks (Fiedler, 1967). However, from the evidence provided organizations are different, face different situations and require different ways of managing (Robbins, Bergman, Stagg and Coulter, 2008). According to situation leadership model managers should adjust their style base on followers readiness to become more successful leader. Thus, as a consequence, managers still need to adapt their management style to fit the needs of the employees. This essay has attempted to examine whether managers need to be able to adapt their management style to fit the needs of the employees. While the evidence expresses that manager does not need to change their style because manager is not effective in all situations and organizations can improve leaders effective by change the situation to fit the manager or change the leader to fit the situation, the reasons managers should change their style can arise from organizations are different, face different situations and require different ways of managing and successful leadership is achieved by selecting the right leadership style, which is contingent on the level of the followers readiness. As a consequence, I consider that managers need to change their style to be more successful and be able to fit the needs of the employees.

Just like how we learn to talk, we mimic our parents behavior. Parents are our biggest influence on us. They should show us their good morals. Of course everyone isn’t perfect, and we all make mistakes, yet when we do something wrong in front of a child we say something a long the lines as â€Å"What you just saw, don’t ever do it.† because we don’t want our children to do what we think is wrong.

Touchstone anthology of contemporary creative nonfiction Essay

Comparative essay assignment Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   â€Å"In the Trenches† written by Charles Yale Harrison and â€Å"This Is Not Who We Are† written by Naomi Shihab are two different pieces of work which outline almost the same message. The analysis of these two stories differs in various ways such as application of styles, themes and imagery as articulated in each of the writings. Both contexts give a description about the occurrence of wars in the twentieth century in America but in different parts.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the trenches which are written by Canadian writer Charles Yale Harrison is a story about the Canadian war which starts in Monreal, a place where an unidentified soldier who is twenty years old is together with Canadian soldiers formulating to set up the Germans in Belgium and France. In this writing, a horrifying and realistic portrayal is described in an antiwar statement. This story is expressed from the first person point of opinion of a soldier who is in a trench. The writer begins the story by describing his close relationship with his fellow soldiers; Anderson, Brown, Broadbent and Cleary and then shifts to the scenes of the infamous World War 1 trenches whereby the conditions are filthy and the soldiers are continually exposed to the flesh-looting rainfalls, lice and huge rats (Harrison, 2002).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   However, Naomi Shihab, Arab-American poet is the writer of â€Å"This is not who we are† which is almost similar to the â€Å"in the trenches† although the writer of this story depict it in form of a poem. This story begins with the writer’s personal life who seek relative safety in the American southwest which is a place torn by war. She describes her marital and emotional connection to Palestine since this is her ancestral homeland. The writer offers evidence of life in safer environment which she feels the disgrace of being an Arab in America at a time when every Arab is considered suspect, including her (Nye, 1997). Nevertheless, the introduction of these two stories brings a perspective on what the entire story is all about. The ideas between the two stories are presented in a different way depending on the kind of structure and form of each author. Therefore both contain different or similar themes, styles and li terary devices in delivering the message which the author wants to communicate. Styles   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Both stories have employed styles in communicating the message to the targeted audience in form of simile, metaphor, personification and imagery. Similes is the main style applied in both contexts, Naomi Shihab, the writer of â€Å"This is not who we are† begins by describing Arab-American skillful violinist as a stylish man who dresses decorous black suits and white shirts and plays like an angel. The writer adds that she wish for world symbols rather than the expensive American vehicles which wear American flags like hula skirts. This shows how she wished that the war could end rather than being prosperous and rich in a violent land. Moreover, the writer proceeds to describe the world that she wished to be and there is application of another simile when she states that she can â€Å"treasure the welcoming world of women†¦, smiling, nurturing, fixing, tending and wrapping language around one another like a warm cloak†. Similarly, Charles Yale Harrison has also applied similes in his writing when he was in the trench and states that he seen the whole army of wire posts beginning to move like a silent host towards him (Harrison, 2002). As the condition of war worsens, the writer depicts the boys who were in firing-step saying that they were like dead men.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In addition, as the soldiers struggles in the dirt trench to save their lives, the writer applies simile by stating that they try to hideaway into the ground like frightened rats. However, Charles Yale Harrison describes the red-tailed comets which were sent by the Germans as looking pretty like the fireworks they have left in Monreal adding that the sky is lit by hundreds of extravagant fireworks like a night carnival which sounds very ironical. During the process of protecting themselves from the explosives, the writer illustrate using a simile stating that the soldiers thrown their faces downward on the bottom of the grovel and trench like savages before that demoniac havoc. The application of similes in these two stories helps the audience to generate a kind of comparison which improves the understanding of what is going on.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Moreover, metaphors and imagery has been applied in these two stories. Naomi Shihab (1997) describes the terrorist as men with hard faces who do vicious things. Although the terrorists are Arabs, the writer does not refer them as Arabs since she is one of them and wants to show that all Arabs are not terrorists. The behavior of men with the hard faces causes the writer to defend herself and her people against the idea that she is one of those with hard faces who choose fierceness over words. This demonstration serves a major drive of explaining that blaming all Arabs because of behavior of the few terrorists is unfair. The writer states a story about a gentleman who approaches her; this makes her afraid because she a half Arab thus this makes her to be momentarily tongue-tied but later finds her voice. Correspondingly, Harrison applies much of imagery and metaphors while describing the nature of the trench during war. He states that the tr ench is unsanitary due to the presence of mud, huge rats, flesh-rotting rainfalls and lice (Reid, 2004). The condition of the trench does not keep soldiers comfortable since they struggle to protect themselves from explosives of their enemies yet the place they are hiding is not safe. This story is distressing and upsetting; illuminating the certainties of war through the eyes of a young soldier and the impressions they fragment. Themes   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Theme of war is general from both stories since the principal message is about the occurrence of war. This theme develops strongly in â€Å"In the Trenches† written by Charles Yale Harrison, war between his fellow soldiers and the Europeans begins from the first line up to the last line. According to the writer, the war is horrifying and we find a sense of shock at the cruelty of war which alters depression to the soldiers. Charles Yale Harrison’s memoir leads us to wonder about why humans continue to retort to war in response to worldwide clashes while being fully conscious of its ferocity (Williford and Martone, 2007). The writer states how one of his fellow soldier said loudly as they argue that no wonder they are losing the bloody war. Moreover, the writer keeps stating that â€Å"so this is war† in many parts of the story thus depicting that the war is occurring. Conversely, Naomi Shihab describes the theme of war in form of terrorism which is caused by the men with hard faces. She describes his ancestral land as â€Å"a place torn by war†, (Williford &Martone, 51). This can evidently show the presence of war when she was writing this story.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   However, theme of suffering is another theme which has been described in both pieces of writing. Harrison begins describing the theme of suffering by describing how his friend by the name Fry suffers with his feet, as he keeps sliding into holes and creeping out, all the way up. The writer adds that he can hear his friend coughing and panting behind him. In addition the writer states that his nose is bleeding from the force of the detonations (Reid, 2004). Generally, Harrison gives description on how they are affected by the conditions of the trench as they try to protect themselves from the explosives; this brings the theme of suffering plainly. Similarly, Naomi Shihab states that she cannot forget the fate of the people who suffer the daily indignities of surviving in a world at war, of persistent pain caused by the men with hard faces. In addition the writer says that she hold in heart so many distressed individuals because all friends and families of innocent victims affected by war are everywhere. This means that there were many people suffering due to the violence which was happening (Nye, 1997). Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Generally, by comparing the two pieces of writing, I can conclude that they portray the same message but in a different manner and style because both stories focuses heavily on the conceit of war and violence in relation to the society. Harrison brings a clear perspective of the soldiers who were simply unexperienced youths, fighting ineffectively for meaningless ideals. Naomi Shihab brings a general explanation that blaming all Arabs for behavior of the few terrorists is absolute unfair. Both stories shape the future altitudes to war and develop a strong enthusiasm to the audience. References Harrison, C. (2002). Generals die in bed. Toronto: Annick Press. Nye, N. (1997). Habibi.

Developing Yourself as an Effective Hr Practitioner

Developing Yourself as an Effective Human Resource Practitioner The CIPD Human Resources Profession Map The CIPD is the professional body for those working within a HR related role, to â€Å"manage the employer-employee relationship and align an organisation’s culture with its people† (CIPD). Researched through collaboration with business leaders the CIPD has developed a map of the activities, knowledge and behaviours required by the different HR roles to meet current business needs (diagram 1).The map consists of ten Professional areas, four Bands and eight Behaviours. Each area has an extended definition to clarify the key requirements of people who work in that area. Diagram 1 Diagram 1 At the core of the map lie ‘Insights, Strategy and Solutions’ and ‘Leading HR’. These two core elements are considered key areas as they extend across all the elements of the HR profession. Also read: HR Profession Map EssayInsights, Strategy and Solutions relates to the need for a successful HR professional to present and develop strategies and solutions based on a firm understanding of the business, it’s internal environment (vision, values, culture, structure and strategy) and its external challenges (competition, world economy, work/life balance, changing demographics of its workforce, changing legislation etc. ) It demonstrates the profession as a recognised business discipline with people and the organisation at its heart.Leading HR is defined as providing ‘active, insight-led leadership: owning, shaping and driving themselves, others and activity in the organisation’ (CIPD). Great leaders can be found across three main areas of leadership – personal leadership, leading others and leading issues. The ten Professional areas relate to the different roles within HR profession e. g. the requirement of someone operating within an Employee Eng agement role is defined as being responsible for ensuring â€Å" †¦ ll aspects of the employment experience – the emotional connection that all employees have with their work, colleagues and to their organisation (in particular line manager relationship) is positive and understood, and that it delivers greater discretionary effort in their work and the way they relate to their organisation†. The four bands of professional competence define the different levels of work activities and the corresponding responsibilities within each professional area, ranging from administrator to board level.Within the HR Map there is also a useful section on the knowledge and . activities required to transition from one band to the next. Finally the eight behaviours describe how the work activities should be carried out within each professional area. The Agency The Agency, despite being less than two years old, has grown from a team of five to 21 employees – 15 Consultants an d six Compliance Officers. The office is very fast paced and competitive, with Consultants urged to secure new posts for high calibre candidates as quickly as possible.Prospective candidates are invited to come into the branch for a registration interview, where they meet the Consultants who will try and place them within schools. Vivien is an experienced Compliance Officer, supporting three Consultants on her pod. Her role is to meet and greet new candidates when they come in for the registration interview, and check they have supplied the necessary paperwork to meet strict safeguarding guidelines before handing them over their consultant for interview. She works alongside Hans, the lead consultant in her pod.They have a very poor relationship, arguing frequently and demonstrate very little respect for each other’s point of view The Candidate proves to be outstanding and Hans manages to place the candidate in a school within two days. Hans is overjoyed and celebrating loudly in the office, at which point Vivien points out to him that she has Vivien has not completed all the necessary vetting procedures so the candidate does not yet meet the safeguarding requirements to begin work. Hans must now contact the school and delay the candidate’s start date, which inconveniences the school and reflects poorly on the agency.HR CUSTOMERS Consultants Need to meet targets to place high fully vetted high calibre teaching staff in school Consultants Need to meet targets to place high fully vetted high calibre teaching staff in school Managing Director Needs to ensure the company’s strategic objectives are met Managing Director Needs to ensure the company’s strategic objectives are met EMPLOYEE RELATIONS OFFICER EMPLOYEE RELATIONS OFFICER Compliance Officer Need to process high volume of new candidates quickly and accurately Compliance Officer Need to process high volume of new candidates quickly and accurately Diagram 2) (Diagram 2) HOW TO PRIOR ITISE NEEDS ‘Customers do want an HR function with strategic business impact, but this is about solving problems that are strategically important for the business, not about separate HR strategies’ (Hirsh et al) As a result of this lapse in correct protocols the school has threatened to end their contract with the agency, which would have a big impact in the revenue brought in by the pod. Hans is a very successful consultant, and part of his success he will interview a high volume of candidates, averaging 6 interviews per day.Hans has accused Vivien of not processing files quickly enough, letting them pile up on her desk. Vivien responds by telling them she can’t process files when she’s interviewing candidates consistently throughout her day for all three consultants. Vivien has asked in the past to change pods as hers is the most successful so she feels overworked whilst the other Compliance Officers are far less busy. The issues identified in this scena rio are a breakdown in communication, imbalance of workload, and damage limitation to one of the agency’s clients.They order in which they are prioritised – their significance, importance and urgency – must be taken in view of the company’s organisational needs and requirements. When faced with such competing priorities, Stephen Covey’s Grid is a useful tool. In this scenario addressing the school’s needs will fall into Quadrant 1, whilst addressing the poor relationship between Hans and Vivien may fall into Quadrant 2. Good communication is the lifeblood of any successful organisation, the results of which can be detrimental (as in the above scenario).There are many ways of communicating within an organisation, and the method and significance of the message can often determine the best method. TYPE OF COMMUNICATION| ADVANTAGE| DISADAVANTAGE| ELECTRONIC| Provides a record for referral follow-up| Can be impersonal and open to interpretation. | WRITTEN/ POSTER| Easily accessed and visible| The Sender does not know if the communication is received unless a reply is required| VERBAL – FACE TO FACE| Allows immediate feedback | Poor communication ability can interfere with how the message os received. Key elements in providing an effective HR Service. Having an understanding and awareness of the strategic purpose of the company will enable the HR professional to operate in an advisory or educational role, assist in decision making, be proactive by applying an overseeing (or policing) role. Senior managers particularly look to the HR function to have an independent, and challenging, view The key elements of effective HR as identified as: Effective service deliveryChallenges the way in which things are done, to find solutions that are better, cheaper or faster as well as an administrative role in implementing relevant processes and practices. Handling and resolving complaints, informal methods, formal methods, appeals a nd escalation (if required) Effective HR services for employees are seen as supporting, not diluting, the responsibility of the line for people management, and the ability of HR to coach line managers, especially around managing performance, is highly valued.Reinforces the compliance role of the HR/personnel function (both legally and ethically) when it is necessary Building and maintaining good relationships A HR professional needs to have its finger on the pulse of what employees are feeling and how well they are working, balancing the interests of employees with the needs of the business.

I am supervisor.I am involved in HR in my job, as we do not have an HR department. I work with my Manager at present to help conduct annual appraisals, disciplinary procedures and inductions. I have also been involved with redundancies.We are a medium sized company, which has expanded since I joined in 2000 but as we are growing we feel the need to have 1 person to take on the HR role so that all staff have someone official that they can go to with any problems that they may have.HRPM: this is an easy to use table containing behaviours, professional areas and bands of competence. It allows users to assess their capability in the HR role they have chosen – whether it is general or specialist.The two core professional areas are insights, strategies & solutions and leading HR.As an example of insights in my role at work there are quite a few members of staff who are nearing retirement age and will retire within around two ye ars of each other so we will be losing all the experience and knowledge that they bring to their roles within the business whether that be manufacturing cables or within our quality assurance department, So I have suggested that we employ younger people who we can train working closely with these people so that their knowledge can be passed on. This has been proven to work as we have two members of staff who joined us around 6 years ago straight from school and are some of our best operators as we have trained them in the way we work.The core of the map is about developing an understanding of the organisation that the user is working in, clerk of the works, contracts manager, and architect.Performance and reward – this allows individuals within a work place to use their own skills, behaviours and experience by using a reward scheme such as bonuses.Learning and Development: Build individual and organisational capability and knowledge to meet current requirements – in ma ny industries it is necessary to train an re-train employees as companies become more diverse to keep up with competitors for example, at my place of work we are starting to build completely different types of cable harnesses to what we would have been building one year ago so there is a lot of re-training required for all shop floor staff.Band 1 of the HRPM is most essential in the company I work for, as it is customer orientated.When I am doing the HR role full time my main customers will be shop floor staff although I will be working for others such as Engineers, Our Receptionist and the Managing Director.There are 8 behaviours on the HRPM.Curious: This person is open minded and focused on the future of the business they are in, inquisitive and is always thinking of ways to add to their organisation, focused on the future of the business they are in and is always thinking of ways to add value to their organisation.Decisive Thinker: This person takes in data and information and is a fast learner. They use the information they receive in a structured way to identify options and make recommendations.Skilled Influencer: This person can influence stakeholders to gain commitment and support within the company/industry they work within.Personally Credible: This person uses professionalism to bring value to the whole company they work in including stakeholders and peers.Collaborative: This person works very well with other people within and outside of work.Driven To Deliver: This person is determined and resourceful and uses these skills to deliver the best results for their company.Courage To Challenge: This person will speak up for what they believe in even if confontated with resistance and unfamiliar circumstances.Role Model: This person always leads by example, has integrity and independence and balances personal organisational and legal matters very well.Activity 2In my HR role, I have 4 main customers. These are shop floor staff which includes inductions for new members off staff, Engineers and Our Receptionist. Shop floor staff: I sit in on (and will conduct) appraisals. We have a written assessment, which the shop floor staff must fill out before attending the appraisal. This includes questions about personal development. In the appraisal we discuss the types of work they would like to do in the future, any pay/skills upgrades they may be getting and when they can expect to get them by. We also discuss any problems they may be having although we always encourage them to come to us (our manager, the other shop floor supervisor or myself) with any problems as they come up rather than waiting for the appraisal.The shop floor manager currently  conducts the appraisals and I sit in on them and take notes then type up all the outcomes of the appraisal with a copy to be given to the employee. I conduct Return To Work interviews for employees who have had any unauthorised absence(s). This is conducted using a form with set questions asked and recorded by my-self about the nature of the absence. The Employee and myself then sign it and it is then scanned into their personnel file. I have sat in on and taken the minutes for redundancy meetings. I have had a limited role in these. As well as taking minutes, I am there for moral support, as I know all of our employees personally due to My job as a supervisor and the number of years I have worked there.Engineers:When I am a full time HR practitioner, I will be able to support the engineers with any problems they may have with other members of staff such as conflicts about the way the engineers plan jobs and the way they are actually built on the shop floor. This can be an issue for both the engineers and shop floor staff as the engineers quote the times for each job but they are not always accurate so this means that the shop floor staff may appear to not build cables in the allocated time.New Employees:I will be conducting all inductions for new Employees – This i ncludes a walk around the factory introducing them to key members of staff such as our other supervisor, first aid, fire marshals and the other members of staff who they will be working closest with. I will also show them the fire exits, evacuation points and show them the fireboard with everybody’s names on. I will tell them when the fire alarm is tested and register them on out hand scanner, which clocks everyone in and out of the building and is also used for payroll. I will show them where the toilets are and what times their breaks and lunch breaks are. New Employees have to read our health and safety handbook thoroughly.Conflicting Needs:I prioritise these by consulting with my manager and shop floor staff so that I am able to decide what to deal with first. For example, I would deal with a conflict between two or more employees by speaking to them separately away from their normal work environment and if appropriate, I would get them together to talk about the problem. This would take priority over an appraisal or other day-to-day activity.Communication:I use email to communicate at work. The advantage of this is that everything that is said between Myself and the person I am communicating with is in writing and can be referred back to if necessary. The disadvantage of this is that if it is something urgent, the person I am communicating with may not see the email straight away, as many members of staff are not desk bound. Verbal communication: this has the advantage of getting the message across immediately and being able to get an instant reaction both verbally and assessing through their body language. The disadvantage of this is that you would not be able to accurately refer back to the conversation at a later date, as verbal conversations are not always accurately remembered.Printed memo:I use these to communicate anything I need to tell the whole shop floor as they do not have access to email in their workplace. The advantage of this is tha t I can carefully think about and word the memo exactly how I want it to be put across. It is also good because it is in writing and can be referred back to at a later date. The disadvantage is that I cant always get an instant reaction to it as everyone gets it at the same time so will not necessarily inform me of any feedback unless I ask them.An example of all the above methods of communication is that when we unfortunately had to make redundancies some time ago, there was a memo given to every member of staff from their manager to let them know that everyone was at risk of being made redundant. My Manager and I then had to liase with our legal specialists via telephone and by e-mail. We then sat with each individual and let him or  her know if they were being made redundant or not. We felt that sitting down with everyone individually, they would be able to speak about any concerns they had whether they were being made redundant or not.

Confidence Interval for a Mean When We Know Sigma

Confidence Interval for a Mean When We Know Sigma In inferential statistics, one of the major goals is to estimate an  unknown  population  parameter. You start with a statistical sample, and from this, you can determine a range of values for the parameter. This range of values is called a confidence interval. Confidence Intervals Confidence intervals are all similar to one another in a few ways. First, many two-sided confidence intervals have the same form: Estimate  ± Margin of Error Second, the steps for calculating confidence intervals are very similar, regardless of the type of confidence interval you are trying to find. The specific type of confidence interval that will be examined below is a two-sided confidence interval for a population mean when you know the population standard deviation. Also, assume that you are working with a population that is normally distributed. Confidence Interval for a Mean With a Known Sigma Below is a process to find the desired confidence interval. Although all of the steps are important, the first one is particularly so: Check conditions: Begin by ensuring that the conditions for your confidence interval have been met. Assume that you know the value of the population standard deviation, denoted by the Greek letter sigma ÏÆ'. Also, assume a normal distribution.Calculate estimate: Estimate the population parameter- in this case, the population mean- by use of a statistic, which in this problem is the sample mean. This involves forming a simple random sample from the population. Sometimes, you can suppose that your sample is a simple random sample, even if it does not meet the strict definition.Critical value: Obtain the critical value z* that corresponds with your confidence level. These values are found by consulting a table of z-scores or by using the software. You can use a z-score table because you know the value of the population standard deviation, and you assume that the population is normally distributed. Common critical values are 1.645 for a 90-percent confidence level, 1.960 for a 95-percen t confidence level, and 2.576 for a 99-percent confidence level. Margin of error: Calculate the margin of error z* ÏÆ' /√n, where n is the size of the simple random sample that you formed.Conclude: Finish by putting together the estimate and margin of error. This can be expressed as either Estimate  ± Margin of Error or as Estimate - Margin of Error to Estimate Margin of Error. Be sure to clearly state the level of confidence that is attached to your confidence interval. Example To see how you can construct a confidence interval, work through an example. Suppose you know that the IQ scores of all incoming college freshman are normally distributed with standard deviation of 15. You have a simple random sample of 100 freshmen, and the mean IQ score for this sample is 120. Find a 90-percent confidence interval for the mean IQ score for the entire population of incoming college freshmen. Work through the steps that were outlined above: Check conditions: The conditions have been met since you have been told that the population standard deviation is 15 and that you are dealing with a normal distribution.Calculate estimate: You have been told that you have a simple random sample of size 100. The mean IQ for this sample is 120, so this is your estimate.Critical value: The critical value for confidence level of 90 percent is given by z* 1.645.Margin of error: Use the margin of error formula and obtain an error of  z* ÏÆ' /√n (1.645)(15) /√(100) 2.467.Conclude: Conclude by putting everything together. A 90-percent confidence interval for the population’s mean IQ score is 120  ± 2.467. Alternatively, you could state this confidence interval as 117.5325 to 122.4675. Practical Considerations Confidence intervals of the above type are not very realistic. It is very rare to know the population standard deviation but not know the population mean. There are ways that this unrealistic assumption can be removed. While you have assumed a normal distribution, this assumption does not need to hold. Nice samples, which exhibit no strong skewness or have any outliers, along with a large enough sample size, allow you to invoke the central limit theorem. As a result, you are justified in using a table of z-scores, even for populations that are not normally distributed.

Ups a Global Company Essays

Ups a Global Company Essays Ups a Global Company Essay Ups a Global Company Essay Introduction Companies which handle packaging services must be able to provide a variety of options to their consumers. They must be able to meet consumer demands when parcels need to be shipped and received within a designated timeframe. UPS is a global company which meets all of these needs. Describe Main Line of Business of the Company United Parcel Service started out as the American Messenger Company founded by 19 year old James Casey in Seattle, Washington back in 1907. Most deliveries were made on foot or bicycle. It wasn’t until 1919 that the adopted name, United Parcel Service became official. This was because â€Å"United† served as a reminder that every retail expansions were part of the overall organization. â€Å"Parcel† was the nature of the business, and â€Å"Service† was what the organization offered. Today, UPS, as it is now formally known since 2003 has grown to become the world’s largest and leading packaging delivery service via air, ocean, ground and electronic sources to over 200 countries worldwide (UPS). Name Four Countries in which the Company Operates The home base of the United Parcel Service is Atlanta, Georgia. It was in 1975 that they first went international providing services in Toronto, Canada with an air hub now in Hamilton, Ontario. In 1976, services were offered in Germany and domestic air service began in 1989. Six European countries became the focus of international air delivery services with the United States in 1985. The first non-stop delivery service was launched between the United States and Guangzhou, China in 1985 and has since acquired interest in China, providing access to 23 cities which is more than 80% of their international trade (UPS). Implementation of Competition Ethical marketing behavior is one of the greatest assets to the competitive strategy of UPS. This is because it is used to dictate what is morally right and just. These standards drive companies that compete in the global marketplace because they affect social and economic behavior through laws and regulation which can create ethical dilemmas (Kerin, 2011). UPS uses this in order to provide services worldwide because they do not change their ethical standards even though there is a variety of languages and cultures. Another asset was the development of the UPS Logistics Group in 1995, which provides consulting services and management solutions based solely on a consumer’s individuals needs (UPS). Implementation of Target Market The target market for UPS are individual consumers, retail businesses, big and small businesses and any organization which needs mail or parcel deliveries to be shipped to individuals or other businesses either nationally or internationally. Implementation of Product Strategy UPS provides many options to their consumers for delivery services. They are able to set the timeframe of when their packages are to be received at their destination. Consumers are able to estimate costs, track their shipments, schedule pickups, create or cancel shipments and order UPS supplies online through the UPS website or in one of its many retail locations (UPS). It also supplies an online tool function, UPS OnLine Tools, which provides businesses the opportunity to integrate their tracking information, ratings, address validation as well as other functions to help with the businesses (Levy, 2001). Implementation of Distribution Strategy UPS promotes it service through their website, which is one of the most visited sites on the Internet with an average of 20. 7 page views a day and 8,5 million customers daily (UPS). It also provides delivery services by air, ocean, railway, motorcycles or motor vehicles. They are also available to consumers through worldwide retail outlets. Implementation of Communication Strategy UPS uses a variety of mixed media to promote their services to consumers. These include print, online and television advertising. Web sites contain product and service information, news updates as well as contact information and is user friendly (Kerin, 2011). Call center services are available to consumers and businesses, thru leasing, to provide fulfillment and shipping of their products out to their customers. UPS currently provides the back-end support to Nike. om in which they are responsible for all shipments of the Nike products out to their customers who purchased them (Levy, 2001). Implementation of Pricing Strategy The pricing strategy of UPS is based on their competition. They want to establish lower prices in order to retain returning consumers. Prices are individually based on the services needed by consumers. These would include type of transportation needed for delivery, where the package is being shipped to and the timeframe in which it needs to arrive at its destinat ion. Prices for international shipments must be calculated using the currency exchange rate and competitive pricing of the country as well as the income of consumers who live there (Ebert Griffin, 2011). Differences in Implementation: From One Country to Another UPS serves over 200 countries worldwide. Rules and regulations vary. It is important to know the legal terms and conditions, forms needed as well as restricted items for each country in order to make a shipment go through efficiently. UPS provides these items for consumers on their website for potential consumers. Not every country has the same rules so it is imperative for UPS to provide the consumer with everything they need to know to determine what they need when shipping to other countries. Conclusion Delivery services are genuinely needed by everyone. UPS provides low cost services both nationally and internationally which can boost an organization’s success. They supply all the information needed for an efficient shipment. This is why they are the largest packaging delivery service today.

Causes and Correlates of Adolescent Drug

Experimentation with illicit drugs and substance use is common among youth population. This is the most common reason for early onset of drugs which exposes youth to developmental harm and risk of developing mental health problems. Early onset of drug is also associated with depression, anxiety, psychosis and educational under achievement among youth population. Due to such harm and health risk to youth population, it is necessary to evaluate how far policies and programs implemented for preventing early drug onset among youths have mitigated different   risk factors of drug abuse (Modesto-Lowe et al. 2008). The essay particularly evaluates the effectives of this program and preventive strategies to identify strength and weakness in approach. Based on this evaluation, it recommends possible steps to improve current strategies to delay the onset of drugs. As there is emphasis on early intervention to reduce the cost and harm associated with early drug onset among youths, it is necessary to evaluate education programs implemented for youths in Australia. The review of such school based educational programs for preventing alcohol and other drugs revealed that the school-based program has harm minimization goal and it mainly employed the principle of social influence approach or cognitive behaviour therapy (CBT). By this approach, youth were taught to resist external pressure and strengthen their coping skills. CBT helped to analyse and modify the negative thinking pattern and behavior of school children. The CLIMATE program for alcohol and cannabis and other programs like SHAHRP, Life Education, Greenhouse project and Resilient Family Intervention gave mixed results. While CLIMATE, SHAHRP and greenhouse projects have significant effect in reducing risk, the other two programs gave no significant results. The main strength of these inter ventions was that the program was implemented by means of a computer-delivery method. This minimized the cost involved in recruiting and training the staffs for education and guaranteed flexible and consistent delivery of information. However, minimum efficacy was found for those schools which had minimum resource for internet based delivery of prevention and where teachers failed to adapt the program according to the needs of particular school (Teesson et al. 2012). Hence, in the future, it is necessary that resource of the school is developed to deliver internet-based educational program to promote efficacy. The key teachings of the educational program should also be supported by evidence (Bonomo and Bowes 2001). As the above evaluation suggested lack of resource regarding computer based program behind the reason for poor outcome of the program, this section particularly evaluates the effectiveness of the universal computer-based Climate School psycho-stimulants and cannabis module. In the randomized controlled study with secondary school children in Australia, students were randomized to computer-based Climate schools program and the usual health classes group. The Climate program was based on social influence approach to harm minimisation. The impact of the Climate Schools program on school children was that they decreased pro-drug attitude due to better awareness about the ill-effects of cannabis and psychostimulants. The frequency of experimentation use of drugs among children significantly reduced which resulted in subdued uptake. In comparison with children who received usual drug education, climate school group children had better used cannabis less often. The advantaged of computer-ba sed delivery was that use of cartoon story raised interest among children and they could recall the information very well. However, one limitation of the Climate School program is that although it reduced children’s intention to use meth/amphetamine among youths, it could not sustain these intention for longer time (Vogl et al. 2014). Hence, to sustain the long-term knowledge and preventive behavior related to early drug onset, it is necessary to continue ongoing intervention in a sequential and regular pattern. The feasibility of the program can be further increased by encouraging children to bring their own laptop to schools. Among all the alcohol education programs implemented in schools, the Climate Schools, All Stars and Project ALERT   was most effective in yielding positive results for children. Many other programs lacked efficacy because of poor quality of research and inconsistency in approach. The programs which gave evidence of good effect included revealed use of multiple peer-reviewed publications as the reason for good outcome in such programs (Roche et al. 2014). Similarly, the study regarding primary school drug education in UK indicated that impact cannot be measure as understanding of true effects requires long timescale. Therefore, the study suggested that those programs are successful that are long-term and intensive on their goals and employ interacting teaching styles and wider community to mitigate the early drug use (Lloyd et al. 2000). Hence, the review suggest that most effective alcohol education program is dependent on availability of effective resource such as managing accessi bility issues and training staffs in efficiently adapting the program in school setting. Furthermore, extension of supportive network is also essential to guarantee the success of the program such as collaboration with families and local community to bring a cultural change and reinforce preventive message not just in schools but at family and community level too. The National Drug Strategy (NDS) is one of the policies regarding the prevention of substance use, risk and harm in Australia. This was a supply reduction and harm reduction strategy to disrupt supply of illicit drugs, prevent uptake of harmful drugs and reduce drug related to harm to people. The National Drug Strategic Framework was implemented in Australia in 2004 which provided a balanced approach to reducing the supply and demand of drugs. Apart from training, monitoring and evaluation, the policy also focussed on research and other measures to prevent the harm associated with drug use (National Drug Strategy - National Drug Strategic Framework 2017). The goal of the national policy was to set an evidence based prevention agenda by means of strategic mapping of system and pathways that are interconnected with risk factors and outcome.   The strategy was effective as it dependent on extensive review of scientific literature to implement corrective actions for the community. Exte nsive research was done in all areas related to efficacy of different risk and protection model, cost-effectiveness of alcohol and drug interventions, legal status of drugs, patterns of use in early years and impact on individual and families (Butler 2005). There is strong implication of the efficacy of this policy. The developments and actions mentioned in this policy can guide public level action reducing the harm of drug use among youths. In future, there is a need to invest in early childhood development and maximize human potential to take full advantage of the protection and risk reduction approach to prevention of drugs. Cannabis is one of the drugs highly used by adolescent children and young adults. They intermittently use this drug till the age of 20 for experimentation purpose and very few of them proceed to long-term regular use. Considering the high prevalence of lifetime use among females in between 1995 to 2000, a vigorous campaign was launched to take action against this practice. To distinguish harm reduction as a policy goal, the main criteria was to include harm reduction as a primary goal and to plan strategies that can bring net-reduction in drug-related harm. Some of the issues found in the strategy of harm reduction is that lack of longitudinal research on adverse health effects delayed making causal inferences. Secondly, the irrational policy and drug law reform acted as an obstacle in evaluation of action for explicit harm reduction. This issue is widely found in raising awareness regarding harm reduction for cannabis. The most probable chronic harm of regular use include cannabis d ependence syndrome, cognitive impairment, respiratory distress and the harm related to acute use include psychological impact such as dysphoria, panic attacks and paranoia. As adolescents particularly belong to high-risk group for adverse effect of cannabis, there is a need to consider legal harm of preventive cannabis use among youths (Swift et al. 2000). There is a need to develop a balance between harm reduction approach and acceptable public message so that other issues are not exacerbated. A realistic and flexible approach will help to yield positive results. Recent research findings should also be included in the strategy to reduce the harm related to enhance health and well-being of society. There is great argument regarding the implementation of the harm reduction approach into an adolescent context. This debate exists due to the views on zero tolerance and legalization of certain drugs. Zero tolerance approach is also not ethically correct because abrupt ban or disruption may also harm addicted individual or youths. Zero tolerance promotes complete prohibition of any form of drug use. On the other hand, legalization and decriminalization of drugs involves removing criminal sanction for possession and sale of drugs. Many oppose these two steps as by this means drug use will further increase among youths (Bonomo and Bowes 2001). Harm reduction approach can balance these two extreme issues by means of implementing two forms of strategies. The first may focus on reducing harms among drug users and other may focus on those vulnerable to initiating drug use. For example, educational campaigns related to safely injecting drugs can reduce blood borne infection and educational strategies on social context can educate young children about the risk of this drugs in their development stage. This would be a rational and relevant approach to achieve better response and prevent drug-related harm. The review and evaluation of current program and strategies to delay the age of drug onset presents weakness in approach resulting in poor response or wide issues at public level. Although some programs were found to be highly effective in integrating right resource to reduce the use of drugs, other programs failed due to lack of adequate infrastructure and training in staff regarding implementing the program. This problem was mainly seen in educational program implemented at school level. For instance, Climate school program was highly efficacious in reducing drug related in harm in school children, however poor outcome was seen due to limitations in infrastructure and design of the program. To improve the performance of school-based educational program in reducing risk of drug use, there is a need to specifically target high-risk group adolescents. The advantage of focusing on high-risk group is that it will maximize preventive outcome for high-risk students as well as lead to positive health behaviour in other youths (Teesson et al. 2012). Secondly limitation found from the evaluation of approach was that educational programs and modules were prepared without integration of peer-reviewed intervention strategies to prevent drug use. This resulted in poor quality of prevention programs resulting in poor or moderate outcome. Hence, extensive research is required while preparing educational modules so that evidence based public intervention is delivered and the program has the potential to improve health behaviour in long-term too (Jenson and Fraser 2015). Improvement in primary prevention strategies for drug prevention is also necessary so and it should be based on theoretical foundation for prevention. For example, while designing educational programs, social determinants, risk and protective factors of health should be adequately covered (Munro and Ramsden, 2017). There are various public health system model available and selecting of these models should depend on the setting, context and severity of drug use issue in target group. Community based approach is necessary so that not just youths, but teachers, parents and local community groups are involved in curbing the menace of high drug use among children. To promote success of intervention, infrastructure and program should be tailored to the needs of the local community and keys actions should be consistent with overall program objectives (Spooner 2009). The essay focused on the public health issue of high prevalence and early onset of drug use among youths. Youths engage in this practice to experiment or gain the ecstasy of drugs. As many of them shift to lifetime consumption of drugs, it leads to many health related consequences such as drug dependency, psychological problem and paranoia. Hence, the evaluation of current educational program and policies was necessary to analyse the extent to which they are effective in delaying in early onset of drugs.

Critically analyse and assess the trend towards globalization of the Assignment

Critically analyse and assess the trend towards globalization of the banking system and its impact on domestic banks. Identify a - Assignment Example The changes include demands from new trends as well as components within the internal organization that are being redefined. Definition of Research Problem The concept of banking is one which is based on national needs, as well as regional elements which are associated with various groups of individuals. However, globalization is beginning to change the internal and external environment while altering products and services offered by those who are a part of banking. This is now leading to several problems, specifically because of the different needs in various parts of the world. Currency exchanges, cost of living relationships, lending channels and basic operations are now being altered, specifically because of needs that are associated with different regions of the globe. The changes are now leading to alterations in market value and many banks which are either making changes domestically or which are becoming dependent on foreign investments and stocks for new opportunities with b anking (Cetorelli, Goldberg, 2008: 14). The research problem defines the problems which are occurring with global transfers as well as how this is redefining the services, products and transfers that are within various banking systems. Literature Review The concept of global banking is one which is now only beginning to surface as a way to work with the corporation of banking systems. In the past, there were basic services and products which were offered specific to the currency of a location. The services and products combined attributes of banking according to one’s culture, capital flows and the financial firms within a specific country. The changes today are now based on an expansion of services and products to help nations in various regions across the world while offering new products and services for changes with global banking. The concept of global banking systems includes the options of lower cost of capital, improved allocation and investments with property rights and institutions. The banking systems are incorporating micro-financing as well as basic services and products which can transfer across borders. Many in other countries are using this as one of the first methods for financing within the country (Mishkin, 2008: 135). The main capabilities for banking systems to establish at a global level come from the enhanced technology which doesn’t define the borders or other applications which are a part of the system. Information processing, telecommunications and other options are providing banks with new alternatives for going overseas. This is combined with the investment opportunities which are continuing to arise for those that are in the different countries. The financial technologies are one of the investments that are leading the way with those who are looking at global expansion from domestic relationships. However, this also limits the products and services which are available and defines a different type of system and sets of services which can be available overseas. Most that are transitioning into this are still experiencing barriers for entry with the government as well as with different needs that are from the technology and the expectations within a given country (Berger, 2007: 1955). Limitations to the Banking System While there are specific aspects that are related to technology, most are finding that this transition is one which is too new to offer complete security

Oil and Gas Management Essay Example | Topics and Well Written Essays - 2000 words

Oil and Gas Management - Essay Example However things are not as simple as they might look. According to various examples and researches it is believed that countries that enjoy abundance in resources are on average less likely to attain economic development in comparison with countries that do not (Heum, Kasande, Ekern, and Nyombi, 2011). Porter (1985) has explored the progressions of various combinations of actions or activities that are performed in order to come up with the final product for the customers. The process involved different actions and services carried out on the specific product from beginning till the end i.e. from extracting the product till the product is manufactured and later distributed to the final customers. However the analysis of Porter can be significantly applied to separate entity or firm (single firm) and can also be applied on number of firms or organizations keeping one thing under consideration i.e. their interconnections amongst each other in the supply chain context or in simple words the link among manufacturers, distributors, suppliers and customers in a specific area or globally (Tordo, Tracy, and Arfaa, 2011). Meanwhile the value chain supply system of the oil and gas industry with reference to social value creation has been highlighted below Oil and gas sector value chain comprises of various procedures initiating from development, processing, transporting and marketing of the product (oil) to the end user or consumers. The process of value chain in the oil and gas sector begins from allocating areas in order to later search or explore those areas for oil and gas. However soon after the basic search for oil or gas, evaluations are carried out on the grounds or fields; development and production are the other two things that are carried out later. The overall procedure is also known as Exploration and Production (E&P) or in other words it is also known as

Commentary Assignment - Essay Example It is believed that cannabis was used during religious ceremonials of the early ethnic groups of people. Shamans and sacerdotes in the ancient times used cannabis to become more religiously enlighted. Cannabis has an effect on the mind and body senses of a person who uses it. Most general and comfortable way to use cannabis is to smoke its dry leaves like tobacco. Cannabis is usually smoked with pipe, hookah, bong or joints (small hand rolling cigars). Usually person who smoke cannabis appear to feel euphory, think in a more philosophical and self-insight way. Individual under the influence of cannabis also has a more receptive feelings especially towards perception of information and food or drinks. If person for example likes music then his listening to the favourite song before smoking cannabis and after will be different. Food seems more pleasant as well as all other kinds of nice things like hot shower, sexual intercourse, reading a book, watching a movie etc. Cannabis influence brain directity and hit receptors which influence emotional, psychic and behavioural condition of an individual. All desirable effects of cannabis like euphoria, sense of pleasentness, more perceptive feelings and other dissappear within a couple of hours after cannabis was used. Though it is a light drug and if talking medically in fact not even a drug it has some bad effects. These bad effect are usually of a long term and depend on the regularity of smoking cannabis and the amount of product smoked. Among negative long-term effects are loss of concentration, clow reaction, sleepliness, inactivity and passive reaction towards the irritants of the environment. However this negative effects do not have somehow significantly negative influence and they appear only if cannabis is used too regularly and in a huge portions. It is also clinically proved that without further using of cannabis such negative effects vanish with no trace of

Chemistry chemistry Essay Example | Topics and Well Written Essays - 500 words

Chemistry chemistry - Essay Example (Frederick, 1979, P.67) Intramolecular forces are much stronger than intermolecular forces hence the generally higher Melting and Boiling points associated with substances that have intramolecular forces. Aluminium, being a metal would be expected to form an ionic bond with Chlorine, which is a gaseous non-metal. This is not the case however due to the very small size of the Aluminium atom, which makes the Aluminium nucleus to exert very high attractive forces on its outer electrons, making it difficult for the atom to loose electrons in order to form ionic bonds. In Aluminium Chloride, the Aluminium atom bonds to three chlorine atoms covalently by having a shared electron with each one of the chlorine atoms. (Frederick, 1979, P.73) Aluminium chloride exists as a dimer (Al2Cl6). The bonding between the two molecules is co-ordinate, using lone pairs on the Chlorine atoms. (Frederick, 1979, P.75) Magnesium has the electronic structu

UK Music Retailers - Assignment Example Businesses operating in any industry are bound to experience changing fortunes in so far as trade is concerned. There are several forces that play in the economy thus influencing the fate of each of the entities in a given sector. With this in mind, it is the sole responsibility for individual business organizations to examine factors within their environment and identify the interventions to keep it competitive. I further use interaction matrix to analyze how the business has changed over time. Finally, I conclude by comparing two players in this music sector and offer some appropriate recommendations. Just like in any other economy of the world, the UK economy also suffers from quite a number of challenges. Being an important component of the economy, UK retailers have not been spared from the difficult moments that occasionally characterize the economy. Therefore, some traditional UK retailers such as music retailers who deal with the selling of music CD and VCD have been critically affected. In the past few years, some famous music retailers went bankrupt one after another. Cases in point include the Towers, KPS, and Virgin. Whilst some of the aforementioned retailers were troubled by the market changes, the likes of Find-CD, which is an online music company, were flourishing (Traynor, 2013). According to the findings of Traynor (2013) in his research, nearly 140 music retailers are prone to the perilous economic period in the near future. A case in point is the HMV music retailer. HMV is credited for having been one of the longest-serving players in the music industry with a history of music retailing of approximately 91 years. It deals with the sale of CDs/DVDs containing music, movies, or video games.

The Rayleigh Ritz Method Computer Science Essay

The Rayleigh Ritz Method Computer Science Essay The given assignment is done with the soul purpose of developing an intense knowledge and understanding of vibrational behaviour and dynamic response of structures. The assignment aims to apply up to date methods of structural dynamics in aerospace and aerospace system engineering. Here we use Rayleigh-Ritz method and Finite Element method to obtain the natural frequency and mode shape of the given cantilever beam. 1. Rayleigh-Ritz Method Rayleigh-Ritz method is an extension of the Rayleigh method which was developed by the Swiss mathematician and physicist Walter Ritz. Its one of the widely used method to calculate more accurate value of fundamental frequency, further it also gives approximations to the higher frequencies and mode shapes. In the Ritz method the single shape function is replaced by a series of shape functions multiplied by constant coefficients, that is the single function of deflection choose in Rayleigh method is assumed to be a sum of several functions multiplied by constant coefficients. The coefficients values are modified by reducing the frequency with respect to each of the coefficients, which result in n algebraic equations in. The solution of these equations will give the value of natural frequency and mode shapes of the system. It should be taken into account that the success of the method is only possible so long as the shape function taken satisfies the geometric boundary conditions of the problem. The method should also be differentiable to the order of the derivatives of the equations. Here the function can ignore discontinuities like shear due to concentrated masses that involve third derivatives in beam. The Rayleigh-Ritz method is done by assuming the deflection curve of the beam by The function are the assumed displacement functions that satisfy geometrical boundary conditions. For a cantilever beam the boundary conditions are They are selected such that it is possible to obtain a good approximation to each of the required natural modes by superposition. The quantities are generalized coordinates representing contributions of each assumed functions. For a beam divided into à ¢Ã¢â€š ¬Ã¢â‚¬ ºn span wise stations the total differential equation can be formulate using Lagrange equation as Putting as a solution , where the amplitude of the displacement is, is the frequency and is the phase angle. This set of characteristics equations can be solved for n discrete values of . This equation can easily be put into a matrix form for numerical calculation as For a beam divided into n span wise station the mass and stiffness terms can be formulated into matrices as Where = matrix of assumed modes = mass matrix = matrix of weighting coefficients = rigidity matrix Hence we write as The above equation is considered to be convenient for computation, but has limitations in the manner of expressing the strain energy.

Finite Element Method Finite Element Method (FEM) is considered to be one of the profound developments in the static and dynamics analysis of continuous systems. It provides a discrete approximation to vibration of continuous systems. The finite element method can be developed as a special case of the Rayleigh -Ritz method. The method was originally developed for the static- stress analysis of complex distributed parameter structures. Now a days FEM is widely applied to disciplines of heat transfer, electro magnetics, fluid flow and vibrations. In finite element method the structure is divided into a large number of small but finite parts called elements which are interconnected at points called nodes. For each element a displacement function is assumed which satisfies the geometric boundary condition so that continuity is achieved between the elements. The variations in displacement of each element( which can be linear, quadratic etc.), are assumed over the length of the element. This method allows the displacement of any point in the element to be expressed in terms of the displacement at the end of the element. These displacements by finite element terminology are called nodal variables. Unlike Rayleigh-Ritz in finite element method the global coordinate is replaced by a local coordinate where is the length of the element. The kinetic and strain energy of the element is obtained by integrating along the elements length, in terms of the nodal variables. By superposing the energies contributed by the individual elements into which the structure is divided, we can obtain the kinetic and strain energy of the structure or system in terms of the nodal variables of the whole structure. The finite element method is mainly based on variational principles. The method is considered very much versatile and can be used to physical problems with arbitrary shapes, loads and support conditions. The finite element model has a close resemblance to the actual structure. Many general finite element code packages have been written over the years with user friendly windows and menus (GUI) which allow for easy geometry setup, boundary condition manipulation and evaluation/post processing of common structural problems. Some of the most popular codes in the industry are ANSYS, MSC Nastran and MARC. ANSYS will be the code used for this assignment. ANSYS Operation Define Material Step 1: Set preferences Preferences are set in order to filter quantities that pertain to this discipline. Step 2: Define constant material properties. Modulus of elasticity, Poissons ratio and Density are defined. Step 3:- Modeling Create the beam with required geometry. Generating Mesh Step 4: Define element type Two element types are defined: a 2-D element and a 3-D element. The beam cross-sectional area is meshed with 2-D elements, and then the area is to be extruded to create a 3-D volume. The mesh will be extruded along with the geometry so 3-D elements will automatically be created in the volume. Step 5: Mesh the area Mesh control are specified in order to obtain a particular mesh density. Element edge length is set at 0.01 Note: Mesh density is very important. If the mesh is too coarse your result can contain serious errors. If the mesh is too fine, would cause waste of computer resources, experience excessively long run time, the model may be too large to be run on the computer system. Unfortunately it cannot be definitively specified how fine the mesh density should be. But one way to find out is to perform the analysis with what seems to be a reasonable mesh. Then reanalyse the problem with twice as many elements in the critical region and compare the results. If the two mesh give the same result then the mesh probably be adequate. If there is substantial difference between the two results then further refinement of the mesh is required. Step 6:- Extrude the meshed area into a meshed volume. The 3-D volume is generated by first changing the element type to SOLID 45, which is defined as element type 2, and then extruding the area into a volume. The number of element divisions is set as 10 Offsets of extrusion are set as 0, 0, 1.5 Tapering ratio is given as 0.33333, 0.25, 0 Apply loads Step 7:- Unselect 2-D elements Before applying constraints to the fixed end of the wing, unselect all the PLANE42 elements used in the 2-D area mesh since they will not be used for the analysis. Step 8:- Apply constraints to the model Constraints will be applied to all nodes located where the wing is fixed to the body. Select all nodes at z = 0, then apply the displacement constraints. Obtain Solution Step 9:- Specify analysis type and options Specify a modal analysis type. Number of modes to be extracted is given as 5 Number of modes to be expanded is given as 5 Step 10:- Solve Observe results Step 11:-List natural frequencies ***** INDEX OF DATA SETS ON RESULTS FILE ***** SET TIME/FREQ LOAD STEP SUBSTEP CUMULATIVE 1 11.964 1 1 1 2 40.840 1 2 2 3 100.05 1 3 3 4 144.08 1 4 4 5 182.70 1 5 5 Step 12:- Animate the two mode shapes.

Repeat the same procedure to obtain the other three mode shapes. First Mode Shape Second Mode Shape Third Mode Shape Fourth Mode Shape Fifth Mode Shape 4. Comparison of Rayleigh-Ritz Method and Finite Element Method Rayleigh-Ritz method Rayleigh-Ritz method uses the principle of conservation of energy to formulate the matrix equation.one major advantage of this method is that it allows us to neglect the non-applied forces like forces at a point of rolling contact, forces at frictionless guides etc. Considering the method to be an extension of the Rayleigh method it has an improved accuracy by assuming the deflection curve of the beam to be Nevertheless the assumed function should satisfy all the boundary conditions and should be linearly independent. This can be easily achieved by using polynomial expression to derive the deflection function. Disadvantages and limitations The selection of assumed deflection function requires a good knowledge and expertise of the method Good approximation of the true natural modes are only possible as the assumed function are limited in numbers and nature All n modal solutions will not give a good approximation to the true mode, so it is necessary to discard some higher frequency modes. The approximations are only good for lower modes and it becomes worse for higher modes. The major limitation of this method is in the manner in which the strain energy can be expressed. Finite Element Method The finite element method (its practical application is often as Finite Element Analysis)is a powerful technique developed in the analysis of complex structural mechanics. In this method the structure is divided into large number of finite parts or elements which are interconnected at points called nodes. The elements will have properties like thickness, Youngs modulus, Poissons ratio etc. An assumption is made over the variation over the length of the element. This allows to find the displacement at any point in the given structure by introducing Disadvantages and limitations The method is not considered convenient for simple structures. Its a time consuming operation. Its accuracy depends on the number of elements the structure is divided. It does not provide a closed-form solution, denying analytical study of the effects of changing parameters. It needs a reliable program for support. Creating a good model requires experience. A good amount of data are required and voluminous output must be sorted and studied. Comparison of results Obtained by Rayleigh-Ritz Method Obtained by Finite Element Method % Difference 0.77% 26.82% There is difference of 26.82% for the second frequency of the system. The value obtained by the Rayleigh-Ritz method can be brought closer to accuracy by increasing the number of assumed functions and by improving their nature. Normally the approximation becomes worse as we move to higher modes .With use of only two assumed functions, the solutions obtained are considered to be satisfactory. Errors in Rayleigh-Ritz method To use the method with ease the assumed functions are kept as simple as possible by using simple polynomial functions and at fewer times only the functions of sine and cosine are used. There is no exact answer as to which function the good approximate value can be obtained. There are always some terms omitted in the function which results to an ineffective solution. This method is considered to be inflexible as the actual displacement of the structure is restricted to only the shape generated by superposing the finite number of functions selected by the analyst. Recommendation to improve Rayleigh-Ritz method The iterative process can be carried out with each time adding the term in the assumed function until it gives the exact value. Errors in Finite Element method Distorted mesh can result in flawed stiffness and mass terms Errors are always presented at joints and constrained boundaries due to uncertainty. Recommendation to improve Finite Element method Iterative method has to be applied to see the number of elements actually required to break down the structure so as to obtain more accurate value. Appropriate methods should be employed for remeshing like HYPERMESH, Mesh++ based on a posterior error. CONCLUSION The first and second natural frequencies of the given beam are found out by using both Rayleigh-Ritz method and Finite element method, and mode shapes for these frequencies are drawn.
