The World Wide Web Bubble - Research Paper Example The essay "The World Wide Web Bubble" describes the reasons and consequences of one of the speculative bubbles, which took place within the time period of 1997 to 2000. The venture capitalists found record-setting growth in the internet sector as the dot-com companies were experiencing a meteoric rise in the stock prices and as a result, moving faster with reduced caution than usual. These companies chose to mitigate the risk by the start-up of many contenders and left it up to the market to decide that which would turn out to be successful. The low rate of interest within the period of 1998-99 has helped in increasing the total startup capital amount. Some of these dot-com companies had their business model built in such manner which relied mostly on harnessing their network effects by means of conducting operations at a sustainable net loss for the purpose of building the market share. These companies provided their services or their end products to the customers without any costs. They did this with expectation of building enough brand awareness that would help them to charge profitable rates in future. In the financial market, the stock market bubble means a self-perpetuating increase or downfall in the share prices of the stocks of any industry. The bubble occurs in the financial market when the speculators find that there is a rapid increase in the stock value and they plan to buy the stock with the perception that it would rise in future as well rather than because of the fact that these shares are undervalued. Because of this fact many companies were becoming overvalued (grossly). It is due to this reason that when bubble bursts and the share prices come down drastically, many companies

Workplace communication barrier Research Proposal

Workplace communication barrier - Research Proposal Example The paper has mainly focused on the language barriers of Asian organizations as they language barrier has become a common part of these organizations. Language barriers are effecting the performance of employees as well as the managers. Research methodology and data collection is also mentioned in the last of the paper. In conclusion, findings and ethical consideration is also provided. Table of Contents Abstract 1 1. Introduction 3 1.1 Working Title 3 1.2 Overview: 4 1.3 Research Question: 5 1.4 Aims and Objectives/Purpose: 6 2.0 Literature Review 7 3.0 Research Method and  Methodology 17 3.1 Data Collection 17 3.2 Design of the Study 18 3.3 Sample Population 18 3.4 Sampling Technique 18 3.5 Research Methods 18 3.6 Findings 19 3.7 Ethical Consideration 19 Works Cited 21 1. Introduction 1.1 Working Title We are living in a smatter planet where everything is now been programmed, interconnected and been made more intelligent to cope up with the fast growing changes. And this change b rings a lot of new opportunities, specifically for the midsize businesses. According to Andersson (2002: 168), when the organizations faced conflict between their employees, these organizations have to face loss. Most of the organizations are facing challenges such as communication barriers and obstacles. But with the growth of more challenging and exceptional scale of requirement for supply and demand, the midsize companies started to face the difficulty to meet the dispute on an overall basis. To find the solution for such unprecedented challenges, the organizations has planned to increase communication and remove conflicts form the employees, so that, the organization may gain higher profitability and productivity. According to Akkirman (2005: 398), the organization has started work to remove the communication barriers, and carry forward the responsibility of playing the major mechanism behind the global economic growth. My topic is specifically based on the â€Å"communication barriers† that the organization is currently facing, and this is also affecting the business of the organization. In this research proposal my discussion will critically analyze the barriers and issues that the organizations have to face in their employees. The issues will also discuss briefly to know the reasons why the communication barriers are affecting business of the organization. This paper will also illustrate the issues that the employees have to face because of the less communication. According to the Abrell (2004: 44), employees are the most important and essential part of the organization, that’s why it is important to make them satisfied and happy with the policies and strategies. The first interval will present a preface to the theme of study accommodating the rationale and implication of the cream. The subsequent interval will present a detailed appraisal of communication barriers, prominence the preceding delves into carried out in this meadow. The trien nial division will swathe the methodology for this study. The psychoanalysis of result, conclusions and debate will be obtainable in the quadrant section. The quintal content subdivision shall bring the study to a close, given that assumption and functional commendation for supplementary investigation. 1.2 Overview: Most of the managers fail to improve communication and cooperation between the employees because of language barriers. William (2000:87) said that if there would not be a language barrier within the organization then this will definitely lead the team towards the success and effective work. Employees are the essential part of any organization and manager should motivate their employees to work together and provide them friendly environment, so that they may work with each other, and they may help other

How The Modern Police Force Has Developed Criminology Essay

How The Modern Police Force Has Developed Criminology Essay This assignment looks at how the modern police force has developed since it was first formed as the Metropolitan Police force and how it has developed to and expanded. Also how the public perceives the police and what they expect from them. In the early 19th century there was very little organisation in the police force, but as London expanded and the population increased the law and order needed to be maintained. Crime and policy came under investigation and in 1828 Sir Robert Peel organised a committee that provided evidence for his new police bill which is the main thing that led to the police force in London becoming organised. The metropolitan police was first organised in 1829 by Sir Robert Peel and Sir Charles Rowan and Richard Mayne are appointed as Justices of the peace who are in charge of the police force. In 1834 the select committee who inquire into how well the police are working within the metropolis area reported that that the metropolitan police force, as respects its influence in repressing crime and the security it has given to persons and property, is one of the most valuable modern institution. In 1836 the metropolitan police take the bow street horse patrol into its ranks. The select committee the n look into affairs of police officers and recommend that the City of London police should be put under the control of the metropolitan police force. In 1838 the select committee recommends that the marine police section and the bow street runners, who were the first organised and paid police force, and the bow street office is also to be disbanded. All of these recommendations came into effect in this year. The dockyard division of the metropolitan police is formed in 1841 and in 42 the detective department is formed. By 1845 the commissioners aim to have one police officer to every 450 people in the population. By the end of the 1840s there was a large scale enrolment into the special constabulary to help the metropolitan police deal with the chartist demonstrations, the strength of the metropolitan police was 5,288 who were able to perform duty and the population of London at the time was 2,473,758. The black marias were used to move prisoners in 1857. In 1862 there was further r ecruitment into the metropolitan police and the X and Y divisions were formed in west London and Y division in the north and later on they patrolled north east London. The standard height is raised to 5ft 8ins except for the dockyard division which is 5ft 7ins. The police strike for the first time in 1872. The police offices at Great Scotland yard are taken into possession on the 4th October 1875 by the detective department. In 1879 Initial rules for dealing with Murder cases, released on 7 June, stated the body must not be moved, nor anything about it or in the room or place interfered with, and the public must be excluded.. there were 13,319 officers in the metropolitan police force by 1885 for a population 5,255,069. The new headquarters are opened at New Scotland Yard in 1890. In 1895 there were certain qualifications that had to be met to join the police which were they had to be over 21 and under 27 when they joined, they also had to be 5ft 9ins tall without shoes, they also h ave to be able to read well and have readable writing, have a reasonable level of intelligence and be in good health. In the last year of the 19th century the metropolitan police force had risen to 16,000 officers to police 7 million people. The finger print bureau started operations in 1901.when the First World War starts in 1914 24,000 special constables were recruited and by the end of the year there were 31,000 and women were also first recruited in this year to police the women who had taken over most of the jobs the men had done. By the end of the First World War there was another strike for more pay and better conditions and recognition of the union. Women started patrolling in 1919 and the flying squad was formed. The police box system was started on an experimental basis. The metropolitan police forensic laboratory is opened in 1935. The 999 system was introduced in 37. In the 60s the police started using vehicles more instead of foot patrols in the form of the panda car. T he headquarters are moved, in 1967, from the Norman Shaw building to Broadway but keeps the name New Scotland Yard. In 1980 the metropolitan Air Support Unit was first formed. In 1997 the National Automated Fingerprint Identification System was installed (N.A.F.I.S). The requirements to join the police has changed drastically since they first came in in 1895. There are no academic requirements, it is open to graduates and non graduates where as before officers had to have good level of reading and writing but because the education system has developed since the 19th century and everyone has to go to school that isnt usually a problem. There is no longer a height requirement for recruits especially know as there are no restrictions on sex or ethnic background to join the police. the age requirement is very broad now as it is 18 and a half -55 years old, where as before it was between 21 and 27 to join. Applicants still have to be reasonably fit and healthy but now have to go through several fitness tests. The entry requirements to join the police now are now more general as it is open to anyone. Police communications started when the telephone was first invented, police phones and boxes were set up in the cities so that police could check in and report crimes. The police boxes were replaced with the police band radio came in several configuration, some had multiple channels, the radio was usually mounted in a panda car and was used to inform and update other officers on patrol. The radio has developed further into the radio system that is used today which is the airwave radio. The airwave radio is a digital and has replaced the analogue radio. There are many benefits of the airwaves radio some of which are there is improved coverage and speech clarity, also improved security and encryptions of communications, national roaming, scope for mobile data applications and improved ability for inter operational communications between the police and other emergency services. The police needed a new radio system because the old one had become out of date and the digital technology pro vides much better coverage and clearer signals. The TETRA technology covers more of the country so there are fewer gaps in the coverage, TETRA can also cope with major incidents when there are going to be many radios being used at the same time without overloading the network. During the Brixton riots the police were not equipped properly to deal with the situation and not only did many officers get injured but they were also forced to use bin lids for protection. The riot gear has since improved and the padded protection covers the body, there are proper helmets with face guards and the shield that are designed to with stand the situation of a riot. Sikhs in the police are not allowed to join the fire arms unit because they cant wear a helmet due to their religious requirements which are the 5 ks. The one that is the problem is the Kesh or uncut hair. Having uncut hair is believed to be a symbol of holiness and strength and is also a symbol of their wish to move beyond concerns of the body. British Police Sikh Association calls on Home Office to develop ballistic material to allow members to join firearms units. Sikh police officers want to have bulletproof turbans made so that they can be in the fire arms unit. In Sikhism men are required to wear a turban but because of the current police safety regulations they have to wear a helmet but they dont fit on top of the turbans and their religion states that they are not allowed to remove the turban. A ballistic material is being developed that would provide a degree of protection when worn so that Sikh police officers can be involved in fire arms operations, although there is an au gment that Sikhs dont have to wear crash helmets when they are riding a bike or motorcycle under the motorcycle crash helmets(religious exemption) act 1976. Research has begun to find the right material for making the bulletproof turban but it needs to pass the Home Offices tests before it can be issued to officers. Tens of thousands of pounds has already been spent to try and find a wear that Sikhs can wear but will also provide an adequate amount of protection, this happened when a Sikh officer applied to join the counter-terrorist operational Support Unit. Police community support officer (PCSO), work on the frontline with the local police force, providing a visible and reassuring presence on the streets and tackling the problem of anti-social behaviour. It is a full time, paid job. PCSOs have different roles in different forces, but they usually patrol a beat and interact with the public, while also offering assistance to police officers at crime scenes and major events. Depending on where they work, they can deal with minor offences, offer early intervention to help stop or slow down people who are committing an offence, provide support to police on the front line, conduct house to house enquiries, guard and monitor crime scenes and provide crime prevention advice to the general public. Although PCSOs do not have the same powers as regular police officers, they still carry a lot of responsibility, and are a critical part of the police force. They do not carry any of the equipment that regular police use like cuffs because they havent had the training and they dont have the right to enforce the law. Police community support officer will work to complement and support regular police officers, providing a visible and accessible uniformed presence to improve the quality of life in the community and offer greater public reassurance. Police community support officers have a unique role that is designed purely to tackle local anti-social behaviour and issues affecting other peopels quality of life. Police Forces continue to support community support officers because they areproviding a visible and regular patrol, unlike neighbourhood wardens, they are employed by the police and have some powers provided by an Act of Parliament to allow them to directly tackle some anti-social behaviour issues. The term moral panics are mainly associated with Stan Cohen, who used it in his book Mods and Rockers in the 60s. Cohens sociology was a mixture of American labelling theory and left wing British sociology which concerns youth and social class. Societies are subjected to periods of moral panic, a condition, episode, person or a group of people can be thought of a threat to a societies values and interests, its nature is stereotypically presented by the media. Sometimes the focus of the panic always around but can suddenly appear in the publics eye and can easily pass on and be forgotten but it can also be of a more serious nature and be kept in the front of the publics mind which can cause changes to be made in legal and social policies. One of the most remembered uses of the term was in Jock Youngs article in 1971 when he talked about the public concern about drug use. Thompson (1998) came up with five stages in a moral panic. One is something or someone that is defined as a threat to values or interests. Two is the threat is shown as a recognisable form by the media. Three is there is a quick build up of public concern. Four is that there is a response from the authorities. Five is the panic recedes or there are results in social changes. Conclusion The police have changed over the years to make them more efficient at their job of protecting the publics life and property. Thing like the new finger print system have helped to catch criminal and reduce the amount of crime. Police cars have made the police more mobile and capable of attending incidences quicker and the radio has made police able to communicate with any other officers with in their force and also they can report incidences and accidents quicker which allow other services to respond which saves more lives and makes the general public feel safer and trust the police with their safety. The police community support officers may not be able to enforce the law like regular officers but they can act as a deterrent because they are someone in uniform which criminals and law breakers would be aware of, they also provide reassurance to they public and can give information to other people making them aware of causes of crime and what the police do to stop it from happening. Th e police are making sure that all the forces have more women and ethnic minorities so that they can relate to the smaller communities who could other wise be less inclined to approach police because they might think of them as racist due to allegations that were made during the 1980s so having women and ethnic minorities working in the police gives the whole police force a more approachable look.

Islam, Judaism, Catholicism, and Protestantism Essays -- Religion Fait

Islam, Judaism, Catholicism, and Protestantism I. Islam The Muslims’ main sacred text is the Koran, which they believe Gabriel gave to Mohammad from God. Muslims believe that the Koran is the final revelation from God, as the Bible has been â€Å"corrupted† upon translation. My passage is Isaiah 53 where it talks about a suffering servant for Israel. While Christians believe this is a prophecy of Jesus, Muslims believe that Jesus was only a prophet. They believe Jesus was never crucified, and Allah made someone look like Jesus instead. (Koran 4:157) Interestingly enough, when our Muslim consultant, Dr. Akhter, was asked about Jesus’ teachings according to the Koran and how it may relate to this passage, he said that he does not know of His teachings. Thus, the suffering servant, according to Islamic teachings, is the man who Allah made to appear identical to Jesus. Regarding Islam, the only area that caught me off guard was when Dr. Akhter stated that Jesus will come back to die and break the cross. The Jihad is another issue that surprised me, because it hardly corresponds to what Allah instructed Mohammad to do in the Koran in countless verses. Dr. Akhter said that a Muslim must fight injustice as a part of the Jihad. Dr. Akhter also surprised me with another statement when I asked him about a hierarchy of prophets in Islam. He said there is a passage in the Koran that states you should not compare a prophet to another. He also talked about the pilgrimage to Mecca and explained how it atones for sins. Once a Muslim experiences the pilgrimage, they have a â€Å"clean slate†. It is a very sensitive issue, because non-Muslims are forbidden to go to the Kaaba. The worship practices of Muslims are somewhat ... ..., anyone that decides to pursue Him as their Savior is a Christian. It is through Jesus Christ that a person is born again spiritually and made alive through Him. WORKS CITED Akhter, Dr. Waseem. Personal interview. February 17, 2005. Allah – the Moon God.

Attachment †Psychology Essay

Developmental Psychology Early Social Development: Attachment Attachment ï  ®Ã¢â‚¬ ¯ An emotional bond between two people. It is a two-way  process that endures over time. It leads to certain  behaviours such as clinging and proximity-seeking and  serves the function of protecting the infant. ï  ®Ã¢â‚¬ ¯ Primary attachment figure ï  ® The person who has formed the closest bond with a child,demonstrated by the intensity of the relationship. Usually  the biological mother, but other people can fulfil the role. ï  ®Ã¢â‚¬ ¯ Learning theory ï  ® A group of explanations which explain behaviour in terms  of learning rather than any innate or higher order  tendencies. Mainly used by behaviourists who rather focus  their explanations purely on what behaviour they observe. Learning Theory ï  ®Ã¢â‚¬ ¯Classical Conditioning (Pavlov) Unconditioned Stimulus (US) – food ↓ Unconditioned Response (UR) – pleasure ↓ Neutral Stimulus (NS) – the feeder ↓ Conditioned Stimulus (CS) – food from a feeder ↓ Conditioned Response (CR) – pleasure/attachment Learning Theory ï  ®Ã¢â‚¬ ¯ Operant Conditioning ï  ®Ã¢â‚¬ ¯ Reinforcement ï  ®Ã¢â‚¬ ¯ When doing something results in a pleasant  consequence, the behaviour is more likely to be produced. ï  ®Ã¢â‚¬ ¯ Punishment ï  ®Ã¢â‚¬ ¯ When doing something results in an unpleasant  consequence, the behaviour is unlikely to be produced. ï  ®Ã¢â‚¬ ¯ Dollard and Miller (1950) explain attachment using operant conditioning: ï  ®Ã¢â‚¬ ¯ When an infant is fed it reduces discomfort and increases pleasure, this serves as a reward and is the primary reinforcer. The person supplying the food is associated  with avoiding discomfort and is the source of reward which  becomes the secondary reinforcer. Attachment occurs  because the child seeks the person who supplies the  reward. Evaluating the Learning Theory ï  ®Ã¢â‚¬ ¯ Strengths It can provide adequate explanations of how attachments form. ï  ®Ã¢â‚¬ ¯ Behaviourists argue that since we are made up of the same building blocks of stimulus/response environments experiments done on animals are safe to generalize to human behaviour. ï  ®Ã¢â‚¬ ¯ Weakness ï  ®Ã¢â‚¬ ¯ It may be attention and responsiveness from the caregiver that is the primary reinforcer, not food. ï  ®Ã¢â‚¬ ¯ Learning theory is largely based on studies with non-human animals. Human behaviour may be similar in many ways but learning theory does not consider higher order thinking and emotions that can influence behaviour. ï  ®Ã¢â‚¬ ¯ Harlow (1959) demonstrated that it is not food but the level of contact and comfort the infant receives that increases attachment levels. The use of young rhesus monkeys were used to demonstrate this. ï  ®Ã¢â‚¬ ¯ 60 babies were studied in Glasgow and found that attachment was higher to the person who was most responsive and who interacted with them more (Schaffer and Emerson,1964). ï  ® ï  ® Cant explain the importance of sensitivity in attachment. Bowlby’s Attachment Theory (1969) ï  ®Ã¢â‚¬ ¯ ELEMENTS OF BOWLBY’S ATTACHMENT THEORY: ï  ®Ã¢â‚¬ ¯ Attachment is adaptive and innate ï  ®Ã¢â‚¬ ¯ Bowlby’s theory is an evolutionary theory because it sees attachment as a behaviour that adds to its survival and  ultimately its reproductive value. Having attachment  capabilities is an innate drive, similar to imprinting, that has long term benefits ensuring it stays close to its caregiver. ï  ®Ã¢â‚¬ ¯ Background on the Theory of Evolution ï  ®Ã¢â‚¬ ¯ Adaptive behaviours are behaviours that increase the  likelihood of survival and reproduction. ï  ®Ã¢â‚¬ ¯ Natural selection is the continuation of these adaptive traits within the animal to increase chances of survival. ï  ®Ã¢â‚¬ ¯ Sexual selection is the ability to reproduce, not just survive. Adaptive genes that lead to possessing traits to assist in  reproduction increases sexual selection. Bowlby’s Attachment Theory ï  ®Ã¢â‚¬ ¯ Sensitive Period ï  ®Ã¢â‚¬ ¯ A biologically determined period of time during the second quarter of the first year is the most crucial period in which attachments can be made. Once missed then it is more difficult for a child to make attachments and demonstrate social difficulties. ï  ®Ã¢â‚¬ ¯ Caregiving is adaptive ï  ®Ã¢â‚¬ ¯ Not only attachment but also caregiving is adaptively innate. Social releasers from the infant give signals to the caregiver (smiling, crying, etc) to take care of it. Attachment is the innate system in babies and caregiving is the innate system in adults. ï  ®Ã¢â‚¬ ¯ Secure base ï  ®Ã¢â‚¬ ¯ Having a secure attachment provides a child with a secure base in which to explore the world from. It fosters independence, not dependence. ï  ®Ã¢â‚¬ ¯ Monotropy and hierarchy ï  ®Ã¢â‚¬ ¯ Infants form a number of different attachments but has one particular bias towards a very special one called the primary attachment, this is called monotropy. Even with secondary attachments, this hierarchy of attachments recognizes the importance of a primary attachment figure (PAF). The PAF is one that responds most sensitively to the childs social releasers. Secondary attachments are important, without them, children tend to lack social skills. Bowlby’s Attachment Theory ï  ®Ã¢â‚¬ ¯ Internal working model ï  ®Ã¢â‚¬ ¯ A mental model of the world that enables individuals to predict and control their environment. The internal  working model based on attachment has several  consequences: ï  ®Ã¢â‚¬ ¯ In the short-term it gives the child insight into the caregivers behaviour and enables the child to influence  the caregivers behaviour so that a true partnership can be formed. ï  ®Ã¢â‚¬ ¯ In the long-term it acts as a template for all future relationships because it generates expectations about  how people behave. ï  ®Ã¢â‚¬ ¯ The continuity hypothesis ï  ®Ã¢â‚¬ ¯ The idea that emotionally secure infants go on to be  emotionally secure, trusting and socially confident adults. Evaluating Attachment Theory ï  ®Ã¢â‚¬ ¯ Strengths ï  ® ï  ® ï  ® ï  ® ï  ® Lorenz (1952) supports that imprinting is innate as the goslings imprinted on the first thing they saw moving, which was Lorenz. Research shows that once the sensitive period has passed and no attachments are formed, children display social difficulties with peers. If attachment and caregiving are an important biological function as Bowlby suggests then they would be found universally. Tronick et al (1992) studied an African tribe in Zaire and found despite tribal responsibility for raising kids a PAF is present. This is also evidence of monotropy. Schaffer and Emerson found that the more quickly a caregiver responded to a childs needs and the more interaction they had led to a stronger level of attachment. This interaction is important as it is not enough to have something to cuddle but to actually be cuddled back builds a stronger attachment. The Minnesota longitudinal study (2005) found that continuity between early attachment and later emotional/social behaviour. Infants classified as secure were later rated highest for social competence, less isolated, more empathetic and more popular. Evaluating Attachment Theory ï  ®Ã¢â‚¬ ¯ Weaknesses ï  ®Ã¢â‚¬ ¯ Multiple attachments, according to psychologists, are as equally important. There are no primary or secondary  attachments, all attachments are integrated into one single  working model. However, a review the research points to the  hierarchical model as being predominant (Prior and Glaser, ï  ® 2006). An alternative explanation to the continuity hypothesis exists, known as the temperament hypothesis. This is the belief that children form secure attachments simply because they have a more ‘easy’ temperament from birth, whereas more innately difficult children a more likely to form insecure attachments. The infants temperamental characteristics shapes a mothers level of responsiveness. Thomas and Chess (1977) identified infant personality types as easy, difficult and slow-to-warm-up. Belsky and Rovine (1987) found a link between physiological behaviours and later attachments types. The more calm and less anxious (aspects of temperament) an infant was the more likely they were to develop secure attachments. Types of Attachment ï  ®Ã¢â‚¬ ¯ The Strange Situation (Ainsworth and Wittig, 1969) http://www.youtube.com/watch?v=QTsewNrHUHU Aim: to see how infants behave under situations of stress  with the introduction of a stranger and the separation of  the parent. This tests stranger anxiety and separation  anxiety and also the infants willingness to explore with its secure base. Procedure: a 9Ãâ€"9 research room marked off into 16 squares  was used. The procedure consists of 8 episodes†¦ MEMORISE THEM!!! Data is collected by a group of observers that recorded  what the infant was doing every 15 seconds. Observer  noted the type of behaviour and level of intensity on a  scale of 1-7. Types of Attachment ï  ®Ã¢â‚¬ ¯ The Strange Situation Findings: ï  ®Ã¢â‚¬ ¯ Ainsworth  combined data from several studies to  make 106 middle-class infants observed. Similarities and differences were found in the way  the infants behaved. In terms of similarities, it was  noted that episode 2 onwards exploratory  behaviour decreased while crying increased. Proximity-seeking and contact-maintaining  increased during separation and when stranger  appeared. Finally, contact-resisting and proximityavoiding behaviours rarely occurred towards the caregiver prior to separation. Types of Attachment ï  ®Ã¢â‚¬ ¯ The Strange Situation Findings: ï  ® Ainsworth found differences in three main types of children. ï  ® ï  ® Insecure-avoidant: this is a style of attachment characterising those children that tend to avoid social interaction and intimacy with others. ï  ® ï  ® Secure attachment: this is a strong and contented attachment of an infant to his or her caregiver which develops as a result of sensitive responding by the caregiver to the infants needs. Insecure-resistant: this is a style of ambivalent attachment characterising  children who both seek and reject intimacy and social interaction. Main and Solomon (1986) re-analysed the strange situation video tapes and created a fourth attachment type: ï  ® Insecure-disorganised: these infants lack a coherent and consistent strategy for dealing with the stress of separation. Secure % of infants (Ainsworth, 1978) % of infants (Van Ijzendoorn et , 1999) Insecure avoidant Insecure resistant Insecure disorganised 66% 22% 12% XXX 62% 15% 9% 15% Evaluating Types of Attachment ï  ®Ã¢â‚¬ ¯ Strengths ï  ® Ainsworth’s Strange Situation technique has given psychologists a means to understand and study attachment which can lead to new future findings. ï  ® Intervention strategies have been developed to strengthen caregiving behaviour and attachments types. The Circle of Security Project (Cooper et al, 2005) which teaches caregivers to recognise signs of distress showed a decrease in disordered caregiving and an increase in secure attachment types. It has proven to be experimentally valid as its construct validity has been demonstrated by other studies supporting the four types of attachments and its predictive validity has been demonstrated in correlations between early attachment types and later behaviours. ï  ®Ã¢â‚¬ ¯ Its findings are also consistent which makes them reliable. Using interobserver reliablity methods, Ainsworth found almost perfect agreement at . 94 between the raters (1.0 is perfect). ï  ®Ã¢â‚¬ ¯ Weakness ï  ®Ã¢â‚¬ ¯ Or does it lack validity, because it is intended to measure the attachment type of an infant, BUT does it really simply measure the quality of a particular relationship? Main and Weston (1981) claim it is measuring one relationship instead of something innate within an individual. ï  ® Evaluating Types of Attachment ï  ®Ã¢â‚¬ ¯ Effects of attachment types ï  ®Ã¢â‚¬ ¯ Bowlby’s continuity hypothesis would predict that a child’s behaviour later in life would be effected by specific attachment types they develop. ï  ®Ã¢â‚¬ ¯ Prior and Glaser (2006) found that in later childhood, if as infants they developed a secure attachment type, they would  be less emotionally dependent and possess more  interpersonal harmony. Infants with the other three types  would be more aggressive, negative withdrawn in later  childhood. ï  ®Ã¢â‚¬ ¯ It would also effect you in your adult romantic lives as well. Hazen and Shaver (1987) conducted the ‘Love Quiz’ which  asked questions about early experiences and current love  experiences and found that there were characteristic  patterns of later romantic behaviour associated with each  early attachment type. Evaluating Types of Attachment ï  ®Ã¢â‚¬ ¯ Factors that influence attachment type ï  ® Sensitivity ï  ®Ã¢â‚¬ ¯ Ainsworth developed the Maternal Sensitivity Scale to rate mothers’ behaviour such as sensitivity and insensitivity to infants signals. The scale found: Securely  attached infant Observed  Mothers bx ï  ® ï  ® Insecurely attached infant Avoidant infant Resistant infant  more sensitive,  cooperating Unresponsive to  crying less  affectionate More rejecting and  less attention  giving Preoccupied with  routine activities when  holding infant Maternal reflective functioning ï  ®Ã¢â‚¬ ¯ Some studies have shown low correlations between measures of sensitivity and strength of attachment. Slade et al (2005) found the ability to understand what someone else is thinking or feeling may be more important. Temperament ï  ®Ã¢â‚¬ ¯ May play a role as previous research indicates, but it is unclear. Cultural Variations in Attachment ï  ®Ã¢â‚¬ ¯ KNOW the definitions of culture, cultural variations and the difference between individualistic and collectivistic cultures (pg.45) ï  ®Ã¢â‚¬ ¯ Cross-cultural Similarities ï  ®Ã¢â‚¬ ¯ Ainsworth’s Uganda study (1967) ï  ®Ã¢â‚¬ ¯ Tronick et al (1992) study on the African tribe in Zaire ï  ®Ã¢â‚¬ ¯ Fox (1977) infants in Isreali kibbutz raised by  nurses when tested in the Strange Situation  appeared equally attached to both caregivers,  except in the reunion behaviour where they  showed greater attachment to their mothers. Cultural Variations in Attachment ï  ®Ã¢â‚¬ ¯ Cross-cultural Differences ï  ®Ã¢â‚¬ ¯ Grossman and Grossman (1991) found that German infants appear more insecurely attached rather than secure. This may be due to the different childrearing practices as German culture involves keeping some interpersonal distance from the parent and infant. ï  ®Ã¢â‚¬ ¯ Takahashi (1990) used the Strange Situation on a group of 60 middle-class infants in Japan and found similar rates of secure attachment. However, the infants showed no evidence of insecure-avoidant and high rates of insecureresistance (32%). Different childrearing practices can explain the difference for in Japan the infants are rarely ever separated from their parents which is why they would be more distressed than their American counterparts. ï  ®Ã¢â‚¬ ¯ Conclusions ï  ®Ã¢â‚¬ ¯ These studies suggest that the strongest attachments are still formed with their mothers and that there are differences in attachment that can be related to differences in cultural attitudes. ï  ®Ã¢â‚¬ ¯ Meta-analysis study by Van IJzendoorn and Kroonenberg (1988) examined over 2000 Strange Situation classification studies in 8 countries. They found the variation between countries and culture were small with secure attachment being the most common in all countries followed by insecure-avoidant except in Japan and Israel. Variations within cultures however were greater. In conclusion the findings appear to be similar to that found in the US and this supports the view that attachment is an innate and biological process. Also data collected on different subcultures should not be generalised to be representative of a particular culture. Criticisms of Research on Cultural Variations ï  ®Ã¢â‚¬ ¯ Culture bias ï  ® ï  ® ï  ® Rothbaum et al (2000) argued that attachment theory and  research is not relevant to other countries because it is rooted in American culture. For example, the sensitivity hypothesis reflects western ideas of autonomy whereas in Japan sensitivity is about promoting dependence. The continuity hypothesis states that  secure infant attachments create more competent adults, however, this ‘competence’ is defined in terms of individuation. The secure base hypothesis in the west explains secure attached infants as independent and confident exploring whereas in Japan they  promote dependence and the concept of amae and so this can  explain why insecure-resistant behaviours are more typical. Rothbaum concludes that psychologists should produce a set of indigenous theories that are explanations of attachment that are rooted in individual cultures with a small group of universal principles (infant need for protection) but mostly with childcare practices relating to cultural values. Rothbaum was challenged by Posada and Jacobs (2001) which shows that attachment theory does apply to most cultures. Criticisms of Research on Cultural Variations ï  ®Ã¢â‚¬ ¯ Criticisms of cross-cultural research ï  ®Ã¢â‚¬ ¯ Tests  of procedures used may not be equally valid  in the country and may make the culture appear  Ã¢â‚¬Ëœinferior’ or ‘abnormal’. This is an example of  imposed etic. This is when a research method is  used in one culture even thought it was designed to  be used in another (intelligence tests or observations). ï  ®Ã¢â‚¬ ¯ The group that was tested may not be  representative of the culture and yet researchers  might make generalisations about the whole culture  or even the whole country. Disruption of Attachment ï  ®Ã¢â‚¬ ¯ Effects of Separation ï  ® ï  ® ï  ® ï  ® Spitz and Wolf (1946) observed 100 children in an institution became severely depressed after a few months. Skeels and Dye (1939) found similar children scored lower on intelligence tests. Bifulo et al (1992) found that negative effects of deprivation may occur later in life. When 249 women who had lost their mothers before they were 17 were studied, it was found that they were twice as likely to develop depressive/anxiety disorders later in life. Robertsons (1967-73) made films observing the effects of separation in children: ï  ® ï  ® When given a high level of emotional care and similar structures to that of their home life, the children exhibited some signs of distress, however, slept well and did not reject their PAF when they were reunited. Some were even reluctant to part with the foster mother which is a sign of a good emotional bond. John, however, was in a nursery and not given such attention. He became withdrawn and gave up on proximity seeking bx. When he was reunited with his mother he rejected her for months and demonstrated outbursts of anger towards her. Disruption of Attachment ï  ®Ã¢â‚¬ ¯ Physical and Emotional Disruption ï  ®Ã¢â‚¬ ¯ As the research evidence shows differences in the way physical and emotional attention is given can produce  negative effects in children. However, there are studies  that show these ill effects can be reversed. ï  ®Ã¢â‚¬ ¯ Sigvardsson (1979) studied over 600 adopted children in Sweden and at the age of eleven, 26% of them were  classified as ‘problem children’. However in a follow up study, ten years later they were no worse off than the  average population. ï  ®Ã¢â‚¬ ¯ So when alternative emotional care is provided, ill effects of separation can be reversed. However, for some  children disruption of attachment leads to permanent  difficulties. ï  ®Ã¢â‚¬ ¯ To criticise the validity of the research consider that they are based on case studies. Weakness of case studies are  that they are based on generalisations and they depend on  objectivity of the observers and are prone to observer bias. Failure to Form Attachment ï  ®Ã¢â‚¬ ¯ Isolated children ï  ®Ã¢â‚¬ ¯ Privation is the lack of having any attachments due to the failure to develop such attachments early in life. ï  ®Ã¢â‚¬ ¯ Genie ï  ® ï  ® The Czech twins ï  ® ï  ® Locked in a room by her father until she was 13. When discovered she could not stand erect or speak. She was disinterested in people and never recovered socially. Locked away by their step-mother until the age of 7. Were looked after by their sisters and by 14 had normal social and intellectual capabilities. By 20 they had above average intelligence and excellent social skills. Evaluation ï  ® Was unclear whether or not Genie was retarded at birth or if she ever formed an attachment with her mother. The Czech twins may have formed attachments to each other to compensate for complete lack of care. It is difficult to reach firm conclusions based on only these cases. Failure to Form Attachment ï  ®Ã¢â‚¬ ¯ Institutional Care ï  ® ï  ® Multiple studies show that the effects of institutionalisation within children is acute distress. Longitudinal studies have been conducted to see what long term effects are caused by institutionalisation. ï  ® ï  ® Hodges and Tizard (1989) followed a group of 65 British children from early life to adolescence. Children have been place in an institution from before they were 4 months old. Children have not yet formed attachments at this age. An early study found that 70% of the children were not able to care deeply for anyone. The children were assessed regularly up to the age of 16. Some children remained while most were adopted or restored with their original families. The restored children were less likely to develop an attachment with their mothers but the adopted ones were as closely attached to their adopted parents as the control group. However, both groups had problems with peers and showed signs of disinhibited attachment. These findings suggest that early privation had negative effects on the ability to form relationships even when given good subsequent emotional care. If failure to develop attachments after the sensitive period occur it can have an irreversible effect on emotional development. Failure to Form Attachment ï  ®Ã¢â‚¬ ¯ Effects of Privation and Institutionalisation ï  ®Ã¢â‚¬ ¯ Attachment disorder ï  ®Ã¢â‚¬ ¯ This has been recognised as a psychiatric condition and has been included in the DSMIV. There are two kinds of attachment disorder, inhibited and disinhibited. Children with an attachment disorder have no PAF, cant interact or relate to others before the age of 5 and have experienced severe neglect or frequent changes in caregivers. ï  ®Ã¢â‚¬ ¯ Poor parenting skills ï  ®Ã¢â‚¬ ¯ Harlow’s monkeys that were raised with surrogate mothers went on to become poor parents. Also, Quinton et al (1984) found similar findings when he compared 50 women who had been raised in institutions. When the women were in their 20’s the ex-institutionalised mothers were experiencing extreme difficulties acting as parents. ï  ®Ã¢â‚¬ ¯ Deprivation dwarfism ï  ®Ã¢â‚¬ ¯ Physical evidence by Gardner (1972) that institutionalised children are physically underdeveloped, potentially caused by stress hormones. ï  ®Ã¢â‚¬ ¯ Evaluation ï  ®Ã¢â‚¬ ¯ In the study of Romanian children, one-third recovered well despite not establishing a PAF prior to the sensitive period. Therefore, privation alone cannot explain negative outcomes. This suggests that damage occurs when there are multiple risk factors (Turner and Lloyd, 1995). ï  ®Ã¢â‚¬ ¯ Not sure if the children failed to form attachments early in life. Maybe they did and the problems they experienced later were more related to rejection. Impact of Day Care ï  ® ï  ® Day Care – the form of temporary care not given by the family or someone well known to the child and usually outside of the home. Social development – the aspect of a child’s growth concerned with the development of sociability, where the child learns to relate to others and with the process of socialisation, the child learns social skills appropriate to the society. ï  ®Ã¢â‚¬ ¯ Negative effects on social development ï  ®Ã¢â‚¬ ¯ Meta-analysis from findings of 88 studies supports Bowlby’s research that prolonged separation from the PAF leads to maladjustment. Violata and Russell (1994) concluded that regular day care for more than 20 hrs a week had an unmistakable negative effect on socio-emotional development, behaviour and attachment of young children. ï  ®Ã¢â‚¬ ¯ NICHD in USA conducted a longitudinal study of over 1000 children. Parents were interviewed regarding the effects of regular day care. The study showed  that the more time a child spent in day care, regardless of quality, the adults rated them as more disobedient and aggressive (NICHD, 2003). The children in day care were 3 times more likely to demonstrate behavioural problems than children that were cared by their mothers. Melhuish (2004) found evidence that children with high levels of day care in the first two years of development had elevated risks of developing anti-social behaviours. ï  ®Ã¢â‚¬ ¯ The Minnesota longitudinal study demonstrated the more securely attached infants are the more popular with peers they become. So therefore, the more insecure an infant, more peer related problems could be expected. Belsky and Rovine (1988) assessed attachment in children in day care and found that were more likely to be insecurely attached compared to children at home. Impact of Day Care ï  ®Ã¢â‚¬ ¯ Positive effects on social development ï  ® ï  ® ï  ® ï  ® ï  ® Good day care provides plenty of social stimulation, whereas, children living at home may lack social interactions. Brown and Harris (1978) found depressed mothers contributed  their low moods to being isolated at home with children. Depressed mothers are likely to form insecure attachments with their children which would have a negative effect on their children. Therefore, the independence gained with having a child in day care is a way to prevent this. Clarke-Stewart et al (1994) studied 150 children and found they were consistently more compliant and independent. The EPPE followed 3000 children in pre-schools and found increased sociability (Sylvia et al, 2003). Day care exposes children to their peers thus enabling them to develop social strategies (negotiate and make friends). Field (1991) found a positive correlation between the amount of time in day care and the number of friends children have once they enter school. Also, those that started day care before 6 months were more sociable than those that started later. Evaluating Research on Day Care ï  ®Ã¢â‚¬ ¯ Weaknesses of research on day care ï  ® When evaluating the research, one must consider the circumstances under which one can find positive or negative outcomes. ï  ® ï  ® ï  ® ï  ® Prodromidis (1995) found no correlation between Swedish children in day care and aggression. Freidman from NICHD explains the aggression study actually shows that day care children may be more aggressive than non-day care, but still 83% of children in day care between 10 -30 hours a week show no signs of aggression. Second important finding from the NICHD research is that the mothers sensitivity to the child, higher maternal education and income all play a more important role in decreased behavioural problems than the amount of time in day care. Finally, the findings are not causal. The data cannot show that day care caused aggression only that there is a link between the two. Therefore, the data suggests that childrens development is more strongly affected by factors at home than those in day care (Belsky et al, 2007). Evaluating Research on Day Care ï  ®Ã¢â‚¬ ¯ Weaknesses of Research on Day Care ï  ®Ã¢â‚¬ ¯ Cannot apply a cause relating to peer relations as  well, only a link. For example, shy and unsociable children have mothers that are shy and  unsociable, therefore, its possible that more  outgoing parents/children that go to day care. ï  ®Ã¢â‚¬ ¯ A lot of research supports the idea that day care  alone has no direct effect on development and  that there are other factors involved. Gregg et al  (2005) analysed findings from the Children of the  90’s study and concluded that for the majority of  children, maternal employment in their first 3  years of life had no adverse effects on behaviour. Evaluating Research on Day Care ï  ®Ã¢â‚¬ ¯ Mediating Factors ï  ® Quality of Care ï  ® ï  ® Individual Differences ï  ® ï  ® As the quality of care decreases it is expected that the attachment type will become poorer. NICHD study (1997) found that low-quality care was associated with poor social development. As parents have different interests in their child, day care staff are less invested and therefore provide a different kind of attention. This is reflected in Howes and Hamilton (1992) findings  that secure attachments  occurred in only 50% of day care staff but 70% in mothers. The NICHD study found the more secure a child’s attachment level is the better they cope with time spent in day care. However, another study showed that insecure children coped better than secure children (showed more aggressive bx) in day care. Child’s age and number of hours ï  ® ï  ® Gregg et al (2005) found that negative effects were more likely to be found in children starting day care before 18 months of age. However, the magnitude of these effects was small. Clarke-Stewart et al (1994) found no difference in attachment between spending a lot of time in day care (more than 30 hours) with those that spend a little time (less than 10 hours). Implications of Research into Attachment and Day care ï  ®Ã¢â‚¬ ¯ Attachment Research ï  ®Ã¢â‚¬ ¯ Attachment research has shown that when separation occurs, negative effects of this separation can be avoided if substitute emotional care can be provided and links to the PAF are made available. This research has changed the way hospitals handle visiting arrangements and the way institutional care is provided. ï  ®Ã¢â‚¬ ¯ A second implication is the way the adoptions process is managed allowing babies to be adopted earlier strengthening child/parent attachments (Singer, 1985). ï  ®Ã¢â‚¬ ¯ Another implication is the improvement of parenting skills, ie, Circle of Security, which improves infant/mother relationships. ï  ®Ã¢â‚¬ ¯ Finally, attachment research has been used to improve day care quality focusing on the importance of secondary attachment figures. ï  ®Ã¢â‚¬ ¯ Day Care Research ï  ®Ã¢â‚¬ ¯ As research shows, high quality care leads to positive outcomes. What is highquality care? ï  ®Ã¢â‚¬ ¯ Low child-staff ratios – 3:1 is ideal for sensitive care to be given ï  ®Ã¢â‚¬ ¯ Minimal staff turnover – allows for consistent care and decreases anxiety ï  ®Ã¢â‚¬ ¯ Sensitive emotional care – only 23% of carers demonstrated highly sensitive care, 50% was moderate care and 20% were emotionally detached. ï  ®Ã¢â‚¬ ¯ Qualified staff – qualified managers lead to better social development ï  ®Ã¢â‚¬ ¯ To ensure high-quality care, legal standards are implemented relating to staff ratio to age of the child, minimum qualifications of staff, Ofsted inspections and finally the sure Start programme.

Pressure Management on a Supercritical Airfoil

Pressure Management on a supercritical aerofoil in transonic flow Abstract-At transonic speeds an aerofoil will have flow accelerate onwards from the leading edge to sonic speeds and produce a shockwave over the surface of its body. One factor that determines the shockwave location is the flow speed. However, the shape of an aerofoil also has an influence. The experiment conducted compared Mach flow over a supercritical aerofoil (flattened upper surface) and a naca0012 aerofoil (symmetrical).Despite discrepancies, the experiment confirmed the aerodynamic performance of a supercritical aerofoil being superior to a conventional aerofoil. A comparison of the graphical distributions demonstrates the more even pressure distribution on a supercritical aerofoil and a longer delay in shockwave formation. All of which, reflects the theory.

Lift is an aerodynamic force which is perpendicular to the direction of the aerofoil. Transonic speeds result in the formation of shockwaves over the top surface of the aerofoil. This is due to accelerated flow over the surface region. We say this region is approximately between 0. 8-0. . Since the flow must accelerate and then will lose velocity following the shockwave the aerofoil will have a subsonic and sonic region. For the majority of commercial airlines this is not a desired region to cruise at given the instantaneous pressure distribution which passengers would otherwise experience. Particularly, the formation of shock induced boundary layer separation. Supercritical aerofoils are more efficient designed for higher Mach speeds and drag reduction. They are distinct from conventional aerofoils by their flattened upper surface and asymmetrical design.The main advantage of this type of aerofoil is the development of shockwaves further away then traditional aerofoils and thus greatly reducing the shock induced boundary layer separation. In order to truly understand the effectiveness of a supercritical aerofoil an experiment gathering supercritical aerofoil performance and raw data of a naca0012 aerofoil will be extensively analysed and compared. Following the calculation and procedureit will be assessed whether a supercritical aerofoil is more effective. ApparatusA wind tunnel with a transonic test section was used in this experiment to study transonic flow around an aerofoil. The test section consists of liners which, after the initial contraction, are nominally parallel apart from a slight divergence to compensate for growth of the boundary layers on the wall. In order to reduce interference and blockage at transonic speeds, the top and bottom liners are ventilated by longitudinal slots backed by plenum chambers. The working section has a height and width of 178mm and 89mm respectively. The stagnation pressure, p0? in the tunnel is close to atmospheric pressure, and therefore it can be taken to be equal to the settling-chamber pressure as the errors are only small. To minimise the disturbance due to the model itself, the reference stagnation pressure, p? , is taken from a pressure tapping in the floor of the working-section, well upstream of the model. The nominal ‘free-stream’ Mach number, M? , in the tunnel can be calculated from the ratio p? /p0?. The Mach number in the tunnel can be controlled by varying the pressure of the injected air, pj. The maximum Mach number that the tunnel can achieve is about 0. 8 Mercury Manometer A multi-tube manometer with mercury was used to measure the pressure at stagnation, the aerofoil tappings and atmosphere. The manometer is equipped with a locking mechanism which allows the mercury levels to be ‘frozen’ so that readings can be taken once the flow has been stopped. Also, the angle of the manometer can be adjusted. For this experiment, it was set to 45 degrees (Motellebi, F. ,2012). Procedure Before conducting the experiment, the barometric pressure, Pat, was recorded, in inches of mercury and the atmospheric temperature, in degrees Celsius, was also recorded.For a range of  values of Pj from 10 – 110 lb/in2, in intervals of 20lb/in2, Pj was then recorded along with the manometer readings corresponding to stagnation pressure (I0? ), the reference static pressure (I? ), airfoil pressure tappings (In, n=1 to 8 and 3a ) and the atmospheric pressure (Iat), all in inches of mercury (Motellebi, F. ,2012). Results- Raw data in appendix x/c Figure 1b Cp against x/c at M= 0. 85 Figure 1a -Cp against x/c at M=0. 85 The experimental data was converted to absolute pressure values using Equation x ( units are inches of mercury).For a given value of the pressure injector (Pinjector) we can find the value of the Mach number using Equation y. Also Equation Z calculates Cp( or pressure coefficents) which reflect the measurements of the surface of the aerofoil. These results are displayed in figure x. This was done for both the supercritical aerofoil and the NACCA 0012 aerofoil. What follows is a comparison and analysis of the data. ( Figure 2b Cp against x/c at Mach speed 0. 8 Figure 2a -Cp against x/c at Mach speed 0. 81 x/c x/c Figure 3b- -Cp against x/c at Mach speed 0. 72 Figure 3a –Cp against x/c at Mach speed 0. 3 Figure 4b –Cp against x/c at Mach speed 0. 61 Figure 4a –Cp against x/ c at Mach speed 0. 61 Figure 5a- -Cp against x/c at Mach speed 0. 45 Figure 5b- -Cp against x/c at Mach speed 0. 44 Note that for both supercritical and naca0012 aerofoils the supercritical cases ( where M is equal to 0. 77, 0. 83 and 0. 840) the approximate value of x/c % where the shock occurs over the aerofoil is shown in red line. For the point below where Cp and the Cpcritical and hence the drop in Cp is greatest gives the location of where the shockwave occurs on the surface of the aerofoil. Cp and Cp* vs M? naca0012 aerofoil) Cp and Cp* vs M? (supercritical aerofoil) It is worth noting that for both the supercritical and Naca0012 aerofoil the results are somewhat similar. That is the critical Mach numbers for both are around 0. 72. Therefore the Minimum Mach number for a local shockwaves on both the supercritical and conventional aerofoil can be assumed to be the same. It is worth noting that Mach number 0. 41 for the supercritical aerofoil does not produce a shockwave, where as the Naca0012 aerofoil does. Mach number| Supercritical Aerofoil Approx position of shock| naca0012 Approx position of shock| 0. 5| -| -| 0. 61| -| -| 0. 72-0. 73| -| 0. 25x/c%| 0. 85-0. 86| 0. 70x/c%| 0. 40x/c%| Basic transonic theory An aerofoil or any object for that matter travelling through a medium (air) at low Mach numbers ( typically between 0. 30-0. 40) has flow is subsonic and can be considered incompressible. This means that any change in pressure or density is significant. The speed of sound (a) is dependent on the altitude of the aerofoil/object and the Mach number M is the ratio of velocity: M=va , a=? RT ?is a specific heat ratio, T is thel absolute temperature and R is the gas constant.The combination of these two equations above leads to: M=v? RT Sound is essentially a series of consecutive weak pressure waves emitted from a given source. These waves travel at the local speed of sound. If we assume the aerofoil is travelling towards the source, the source can noti ce the disturbances beforehand giving enough time for flow to adjust around the object. When the source begins to approach near the speed of sound, pressure waves move closer together in front of the object, therefore inadequate information from the source/disturbance is propagated upstream and the flow will not be able to react in time.The pressure waves merge together to produce a shockwave in front of the object. The flow encountering the shockwave will experience changes in temperature, static pressure and gas density as well as a lower Mach number. The transonic region is special because although flight speed is below sonic speed as the information is propagated upstream on the surface of the aerofoil the flow accelerated to the speed of sound. Thus forming a shockwave over the aerofoil. The position of this shockwave depends on the initial entry speed to the aerofoil.Therefore what we have in the transonic region is an aerofoil which has sonic speeds early upstream and subsoni c speed towards the end of the aerofoil or downstream. This means it is complicated to accurately analyse transonic flow over an aerofoil as a different set of equations must be used on the leading edge, upper surface and trailing edge. The critical upstream Mach number is the minimum value of a given Mach number for which a shockwave will be produced on the surface of an aerofoil. In other words, supersonic flow.Below this threshold a shockwave will not appear. Drag or the aerodynamic force in the transonic region again depends on the speed of the object travelling. At subsonic speeds the main component of drag are Skin friction, pressure drag and lift induced drag. At sonic speeds (approaching or exceeding) there is the addition of wave drag. The drag increases dramatically, and as a result a higher thrust is needed to sustain acceleration. Also, at this point the shockwave will interact with the boundary layer, thus causing it to separate upstream of the shock.Figure 6Demonstrati on of transonic flight-(Scott, J. , 2000) The aerofoils The two aerofoils Naca0012 and Supercritical aerofoil are different in design and purpose. The Naca0012 is a basic symmetrical aerofoil used primarily for rudder and elevator movements. Aerodynamic performance is not taken into consideration and is thus reflected by the simple aerodynamic design. It is worth noting that there are better aerofoils. The Supercritical aerofoil is a performance aerofoil designed for higher Mach speeds and drag reduction.They are distinct from conventional aerofoils by their flattened upper surface and asymmetrical design. The main advantage of this type of aerofoil is the development of shockwaves further away then traditional aerofoils and thus greatly reducing the shock induced boundary layer separation. Relating the Theory to the Experiment The critical Mach number for both the supercritical aerofoil and NACA0012 aerofoil was found to be in the region of 0,72. There is a difference to the neares t 10th but for all intents and purposes we can assume they are the same.This indicates that the minimum Mach number for a shockwave to be produced on the surface of the aerofoils is equal and not influenced via the shape. The pressure distributions of the supercritical aerofoil ( especially at Higher Mach) in comparison to the Naca0012 are more evenly distributed. The experiment confirms the theory that the supercritical aerofoil in comparison ro a conventional aerofoil generates more lift due to an even distribution of pressure over the upper surface. (http://en. wikipedia. org/wiki/Supercritical_airfoil) Effectiveness of Supercritical aerofoils.At a Mach number of 0. 45 both aerofoils do not display a shockwave. This is evident from the fact the Cp and Cp* graphs do not intersect at all. We already know this because the critical Mach number is 0. 72 for both. This indicates that either a shockwave was not produced (unlikely), or that the shockwave was produced beyond the trailing edge This means we cannot assess the effectiveness of the supercritical aerofoil at Mach speeds 0,45 and 0. 61. The supercritical Mach numbers show varying results. When the experiment took place at Mach ) 0. 72-0. 3 ( the critical Mach number) the supercritical aerofoil did not produce a shockwave ( Cp and Cp* do not intersect) whereas the naca0012 aerofoil did. The lack of a shockwave formation indicates either the critical Mach number for the supercritical aerofoil is higher then the conventional aerofoil experimental accuracy is lacking. At the supercritical mach numbers ( 0. 81-0. 86) in both the naca0012 aerofoil and the supercritical aerofoil Cp and Cp* intersect. The large drop in pressure coefficient is evidence of the formation of a shockwave.However, the pressure drop in the supercritical aerofoil is occurring at a pressure tapping further downstream. This confirms the theory that a shockwave is produced further downstream in a supercritical aerofoil This seems to confirm the theory that a supercritical aerofoils design does allow for development of shockwaves further away then traditional aerofoils and thus greater reduction in the shock induced boundary layer separation. In regards to the amount of drag (aerodynamic force) acting on the aerofoils it is worth noting that the pressure distribution at 0. 5 Mach for the supercritical aerofoil is more evenly distributed and ‘flatter’ then the naca0012 aerofoil. There is no indication of a large instantaneous increase in drag taking over. This would therefore confirm the theory that a supercritical aerofoil is effective in greatly reducing the shock induced boundary layer separation. Notes for limitations The experiment is a success since results obtained confirm the capabilities of supercritical aerofoils and their advantages over conventional aerofoils. However, there are a few discrepancies which regarding experimental error and the different aerofoils.First of all the mach numbers teste d at 0. 72 and 0. 73 created an inaccurate experiment. Normally, this would not be a problem. However, since the critical mach numbers for both aerofoil’s were in the vicinity of 0. 72 it was expected this was the minimum threshold for a shockwave to be produced over the aerofoil. A shockwave was not produced for the supercritical aerofoil despite the critical mach number value. Therefore, we can conclude that at this speed there are too many inaccuracies to understand what is really going on.We also did not really see a difference in performance at subsonic flow. Granted, the supercritical aerofoil was primarily designed for supercritical mach speed. No useful information was obtained from here. The fact the pressure tappings have different coordinates means that each aerofoil is showing the pressure distribution at a different set of coordinates. This of course, is not as accurate if the aerofoils had the same pressure tappings. For instance, the naca0012 has a pressure tap ping at 6. 5% of the aerofoil section and the last ends 75% the rest is unaccounted for.Since the supercritical aerofoil has different pressure tappings it means both aerofoils have different areas which are unaccounted for. This means it is not certain whether or not the graphs are a reliable source of information, yet alone to compare. A digital meter should also be connected that displays the pressure in the two tappings so the aerofoil can be appropriately adjusted to bring it to zero incidence. This digital meter can also be used to display the value of the mercury levels for other pressure tappings, reducing any human errors.In order to increase the accuracy of the pressure distribution over the aerofoil surface, more pressure tappings can be made on the aerofoil. These will improve the pressure coefficient graphs by allowing more points to be plotted, in turn, yielding better information for the position of the shockwave in the supercritical cases and also the critical Mach n umber for a shock to occur.

Crime and Morality Essay Example

Crime and Morality Essay Example Crime and Morality Essay Crime and Morality Essay Giving recognition to the definition given above, morality describes the rules that govern our behaviour. It guides us or our class of actions. Since childhood. we have been told by our beloved parents to ever make good and act right. We were taught on how to be disciplined. Even in school. since babys room. kindergarten and particularly during simple. good ethical motives and right behavior were ever reminded to us by our beloved instructors. But what happened to these values upon making secondary school? Students in these old ages tend to be more unworried and they want to make things their manner. They crave for independency and freedom taking to rebelliousness and loss of values if their desires weren’t considered by their households. Does that intend that turning up at the same clip losing the virtuousnesss come at the same clip? What happened to the manners that were ought to be followed by bosom? Their was one time a teenage male child that was known in the vicinity to be a stealer since he was immature. He had been caught many times and been to imprison for many times excessively. He is ever doing promises non to make the offense once more but still endures to reiterate the act many clip. He was asked why he’s making such thing at a really immature age where in fact he still hold his parents? He was questioned of non being taught of taking right from incorrect. Then he answered Are ethical motives more of import than the demands that I have to carry through? You are lucky because you have your parents that can supply your necessities. But what about me? My siblings? His resemblance was excessively pathetic that he doesn’t have the parents who are good suppliers. But it conferred to a realisation that we can’t put the incrimination to the parents. The family’s enduring from poorness impacting non merely the family’s base of morality but besides the position of each household member. Crime statistics shows that as of twelvemonth 2007. 65. 944 offenses were committed or 115. 6 offenses per 100. 000 population and 17. 4 % of these were because of robbery. That’s harmonizing to the PNP records. The cause of robberies were chiefly caused by POVERTY. So in the heads of most people and of the Filipinos. contending against hungriness is better than holding an unity with an empty tummy. That there are more of import things to see than merely being in line of making good and unsloped. But isn’t it easier to see contending against poorness and following ethical motives? Than being able to perpetrate offense and unrighteousness because we wanted to accomplish our wants and demands? It’s like rip offing during tests to acquire a high class the same manner easier to analyze hard to acquire high classs. If we merely work hard. there will be mountains difficult plenty to mount and tests that we can’t survive. If we’d merely work on our religion in God. live up our faith to assist us to take the right way of making the good manner and at the terminal. we might acquire what we want and it might be greater than we’d expect.

Biography of Civil Rights Leader Martin Luther King Jr.

Biography of Civil Rights Leader Martin Luther King Jr. The Rev. Martin Luther King Jr. (Jan. 15, 1929–April 4, 1968) was the charismatic leader of the U.S. civil rights movement in the 1950s and 1960s. He directed the year-long Montgomery bus boycott, which attracted scrutiny by a wary, divided nation, but his leadership and the resultant Supreme Court ruling against bus segregation brought him fame. He formed the Southern Christian Leadership Conference (SCLC) to coordinate nonviolent protests and delivered over than 2,500 speeches addressing racial injustice, but his life was cut short by an assassin in 1968. Fast Facts: The Rev. Martin Luther King Jr. Known For: Leader of the U.S. civil rights movementAlso Known As: Michael Lewis King Jr.Born: Jan. 15, 1929 in Atlanta, GeorgiaParents: Michael King Sr., Alberta WilliamsDied: April 4, 1968 in Memphis, TennesseeEducation: Crozer Theological Seminary, Boston UniversityPublished Works: Stride Toward Freedom, Where Do We Go from Here: Chaos or Community?Awards and Honors: Nobel Peace PrizeSpouse: Coretta ScottChildren: Yolanda, Martin, Dexter, BerniceNotable Quote: I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character. Early Life Martin Luther King Jr. was born Jan. 15, 1929, in Atlanta, Georgia, to Michael King Sr., pastor of the Ebenezer Baptist Church, and Alberta Williams, a Spelman College graduate and former schoolteacher. King lived with his parents, a sister, and a brother in the Victorian home of his maternal grandparents. Martin- named Michael Lewis until he was 5- thrived in a middle-class family, playing football and baseball, delivering newspapers, and doing odd jobs. Their father was involved in the local chapter of the National Association for the Advancement of Colored People and had led a successful campaign for equal wages for white and black Atlanta teachers. When Martins grandfather died in 1931, Martins father became pastor of Ebenezer Baptist Church, serving for 44 years. After attending the World Baptist Alliance in Berlin in 1934, King Sr. changed his and his sons name from Michael King to Martin Luther King, after the Protestant reformist. King Sr. was inspired by Martin Luthers courage of confronting institutionalized evil. College King entered Morehouse College at 15. He was uncertain about following in the footsteps of the familys clergymen, questioning religions relevance in addressing segregation and poverty among his people. King rebelled against a life of service to God, playing pool, drinking beer, and underachieving his first two years at Morehouse. King studied sociology and considered law school while reading voraciously. He was fascinated by Henry David Thoreaus essay On Civil Disobedience and its idea of noncooperation with an unjust system. King decided that social activism was his calling and religion the best means to that end. He was ordained as a minister in February 1948, the year he graduated with a sociology degree at age 19. Seminary In September 1948, King entered the predominately white Crozer Theological Seminary in Upland, Pennsylvania. He read works by great theologians but despaired that no philosophy was complete within itself. Then, hearing a lecture about Indian leader Mahatma Gandhi, he became captivated by his concept of passive resistance. King concluded that the Christian doctrine of love, operating through nonviolence, could be a powerful weapon for his people. In 1951, King graduated at the top of his class with a Bachelor of Divinity degree. In September of that year, he enrolled in doctoral studies at Boston Universitys School of Theology. Marriage While in Boston, King met Coretta Scott, a singer studying voice at the New England Conservatory of Music. Coretta hesitated about dating a minister but was persuaded when King said she had all the qualities he desired in a wife. The couple married on June 18, 1953. Kings father performed the ceremony at Corettas family home in Marion, Alabama. They returned to Boston to complete their degrees. King was invited to preach in Montgomery, Alabama, at the Dexter Avenue Baptist Church, which had a history of civil rights activism. The pastor was retiring. King captivated the congregation and became the pastor in April 1954. Coretta was committed to her husbands work but was conflicted about her role. King wanted her to stay home with their four children: Yolanda, Martin, Dexter, and Bernice. Montgomery Bus Boycott When King arrived in Montgomery to join the Dexter Avenue church, Rosa Parks, secretary of the local NAACP chapter, had been arrested for refusing to relinquish her bus seat to a white man. Parks Dec. 1, 1955, arrest presented the perfect opportunity to make a case for desegregating the transit system. E.D. Nixon, former head of the local NAACP chapter, and the Rev. Ralph Abernathy, a close friend of King, contacted King and other clergymen to plan a citywide bus boycott. The group drafted demands and stipulated that no African-American would ride the buses on Dec 5. That day, nearly 20,000 black citizens refused bus rides. Because blacks comprised 90 percent of the passengers, most buses were empty. When the boycott ended 381 days later, Montgomerys transit system was nearly bankrupt. Then on Dec. 20, 1956, the Supreme Court ruled that enforcing segregation on public transit was unconstitutional. Buoyed by success, the movements leaders met in January 1957 in Atlanta and formed the Southern Christian Leadership Conference (SCLC) to coordinate nonviolent protests through black churches. King was elected president and held the post until his death. In early 1958, Kings first book, Stride Toward Freedom, was published. While signing books in Harlem, New York, King was stabbed by a mentally ill black woman. As he recovered, he visited Indias Gandhi Peace Foundation in February 1959 to refine his protest strategies. Birmingham In April 1963, King and the SCLC joined Rev. Fred Shuttlesworth of the Alabama Christian Movement for Human Rights (ACMHR) in a nonviolent campaign to end segregation and force Birmingham, Alabama, businesses to hire blacks. Fire hoses and vicious dogs were unleashed on the protesters by â€Å"Bull† Connors policemen. King was thrown into jail, where he wrote Letter From a Birmingham Jail, affirming his peaceful philosophy. The brutal images galvanized the nation. Money poured in to support the protesters; white sympathizers joined demonstrations. By summer, thousands of public facilities nationwide were integrated, and companies began to hire blacks. The resulting political climate pushed passage of civil rights legislation. On June 11, 1963, President John F. Kennedy drafted the Civil Rights Act of 1964, which was signed into law by President Lyndon Johnson after Kennedys assassination. March on Washington Then came the March on Washington, D.C.,  on Aug. 28, 1963. Nearly 250,000 Americans listened to speeches by civil rights activists, but most had come for King. The Kennedy administration, fearing violence, edited a speech by John Lewis of the Student Nonviolent Coordinating Committee (SNCC) and invited white organizations to participate, causing some blacks to denigrate the event. Malcolm X labeled it the â€Å"farce in Washington. Crowds far exceeded expectations. Speaker after speaker addressed them. The heat grew oppressive, but then King stood up. His speech started slowly, but King stopped reading from notes, either by inspiration or gospel singer Mahalia Jackson shouting, â€Å"Tell em about the dream, Martin!† He had had a dream, he declared, â€Å"that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character.† It was the most memorable speech of his life. Nobel Prize King, now known worldwide, was designated Time magazines â€Å"Man of the Year† in 1963. He won the Nobel Peace Prize the following year, donating his $54,123 prize to advancing civil rights. Not everyone was thrilled by Kings success. Since the bus boycott, King had been under scrutiny by FBI director J. Edgar Hoover. Hoping to prove King was under communist influence, Hoover filed a request with Attorney General Robert Kennedy to put him under surveillance, including break-ins at homes and offices and wiretaps. Poverty In the summer of 1964, Kings nonviolent concept was challenged by deadly riots in the North. King believed their origins were segregation and poverty and shifted his focus to poverty, but he couldnt garner support. He organized a campaign against poverty in 1966 and moved his family into Chicagos black ghetto, but he found that strategies successful in the south didnt work in Chicago. Blacks turned from Kings peaceful course to the radical concepts of Malcolm X. King refused to yield, addressing what he considered the harmful philosophy of Black Power in his last book, Where Do We Go from Here: Chaos or Community? King sought to clarify the link between poverty and discrimination and to address Americas increased involvement in Vietnam, which he considered unjustifiable and discriminatory toward the poor. Kings last major effort, the Poor Peoples Campaign, was organized with other civil rights groups to bring impoverished people to live in tent camps on the National Mall starting April 29, 1968. Last Days Earlier that spring, King had gone to Memphis, Tennessee, to join a march supporting a strike by black sanitation workers. After the march began, riots broke out; 60 people were injured and one person was killed, ending the march. On April 3, King gave what became his last speech. He wanted a long life, he said, and had been warned of danger in Memphis but said death didnt matter because hed been to the mountaintop and seen the promised land. On April 4, 1968, King stepped onto the balcony of Memphis Lorraine Motel. A rifle bullet tore into his face. He died at St. Josephs Hospital less than an hour later. Kings death brought widespread grief to a violence-weary nation. Riots exploded across the country. Legacy Kings body was brought home to Atlanta to lie at Ebenezer Baptist Church, where he had co-pastored with his father for many years. At Kings April 9, 1968, funeral, great words honored the slain leader, but the most apropos eulogy was delivered by King himself, via a recording of his last sermon at Ebenezer: If any of you are around when I meet my day, I dont want a long funeral...Id like someone to mention that day that Martin Luther King Jr. tried to give his life serving others...And I want you to say that I tried to love and serve humanity. King had achieved much in the short span of 11 years. With accumulated travel topping 6 million miles, King could have gone to the moon and back 13 times. Instead, he traveled the world, making over 2,500 speeches, writing five books, leading eight major nonviolent efforts for social change, and being arrested over 20 times. In 1983, President Ronald Reagan created a national holiday to celebrate the man who did so much for the United States. Sources Abernathy, Ralph David.

Bottling it Through Not ''Bottling it '' Essay Example | Topics and Well Written Essays - 1750 words

Bottling it Through Not ''Bottling it '' - Essay Example Through the analysis of the case study of Ecobot, this paper will highlight how a negative culture can affect an organization adversely. Moreover, it will analyze the steps that an organization can adopt in changing culture, and enumerate the effects of adopting a positive culture. Four Main Types of Culture Charles Handy described four types of culture that are common in many organizations. A culture is an important aspect in determining the efficiency of an organization. Culture denotes all the norms, beliefs, practices, rules, values and ideals that an organization esteems and holds. A culture helps an organization get its activities going. Each organization has a unique culture that works best for it. Some organizations may have multiple sets of cultures evident in their behavior. Cultures may exert positive or negative effects on an organization depending on the practices, belief systems, and behavioral patterns of the culture. One of the main types that Handy described is the r ole culture (Bhattacharyya, 2010:58). In this culture, each employee in an organization has a title that describes his or her job. The basis of this culture is the fact that an organization comprises a set of various roles that must exhibit logic and ascertain that the activities of the organization run efficiently. Each individual in the organization has a set of job responsibilities and requirements that define the company’s expectations from the individual. It is worth noting that these responsibilities match the field of expertise of the individual. Within the role culture, communication occurs via memoranda that address each of the job titles. Role cultures require effective management and clear-cut definitions of what the organization expects from a job title and job evaluation. Moreover, this culture presents a situation whereby the level of authority depends on the current job titles. The second type of culture is the task culture. This involves the formation of focus groups that comprises members with certain talents and resources. The organization assigns a task or project to each of the focus groups. This type of culture requires that the team function closely, handling the problems in their project and easing the difficulties that are beyond individual scope (Bhattacharyya, 2010:58). The focus groups often have team leaders rather than managers. Although it proves quite expensive, it can produce remarkable results if there is cooperation in each team. In this culture, the organization pays a high level of attention to its tasks. The third main culture that Handy described is the person culture. In this culture, organizational terms may not come into use. On the contrary, this culture comprises professionals working as individuals. These individuals have a lot of experience and expertise and the organization addresses them in accordance with the level of expertise. An administration team serves the professionals making their work easier. For these professionals to take up a certain task, persuasion, bargaining and influencing are the key approaches used as opposed to management in other cultures. The fourth type of the culture described by Handy is the power culture that operates in a centralized mechanism. Its metaphorical representation is in the form of a spider’s web. This translates to the fact that those closest to the core of the culture have a higher level of influence. Moreover, the boss of the organization finds a way of influencing the views of the workers

Analyse and apply the appropriate marketing strategy in the context of the marketing planning process - Essay Example Through study of some important brands and their respective marketing strategies the overall position and pattern have been gauged in context of marketing strategies. Toyota Motor Corporation is a big player in the world of automobiles. It manufactures various types of cars, trucks, passenger cars and minivans. Under the brand name Prius it sells hybrid vehicles. The company also has a wide range of SUV or sport utility vehicles as well as other speciality vehicles. One of the company’s primary objectives is to manufactures such vehicles which would provide safety, security and comfort to the consumers (Company Description, May 2009; Toyotas ITS vision, 2009). Toyota or for that matter any company would set up strategies to achieve its business goals or objectives. Similarly it creates marketing strategies to achieve its goals in terms of marketing objectives. Marketing strategy as a concept caters to three parts, the internal factors of the company itself, the customer and the competitors of the firm. A marketing strategy of a firm focuses on the market in terms of segmentation, targeting and positioning. Segmentation is dividing the market into groups which have similar characteristics. This is used by the companies to target their products to cater to the specific segments. The company always focuses towards creating a higher position for its products in comparison to its competitors so that it can leverage this and sell more. One of the basic and most important concepts of marketing strategy is that of the 4Ps of marketing which constitute the marketing mix of an organisation. The marketing mix or the 4Ps are; product, price, promotion and placement. Toyota offers a wide array of automobiles. It produces trucks, minivans, luxury sedans and hybrids among many other cars. The company also offers various brands for its various offerings. The Lexus brand is its luxury offering. While the Scion brand

Leadership, Learning and Development Assignment

Leadership, Learning and Development - Assignment Example The fact is that every culture in different countries have differences from one another. At the risk of stereotyping, some cultures are more traditional – they are more masculine, less inclined to accept individual differences, and more respecting of hierarchies. These societies have basic inequalities. Other cultures are the opposite of this. Some cultures are individualist, and some are collectivist. Management must know these cultural differences, and they must have the skills to overcome the differences. They also should have a pragmatic way of dealing with the differences. Moreover, there is also the issue of outsourcing. This is another implication of globalization. When this occurs, there is inevitably a challenge. The employees may feel that they are going to be next, and the atmosphere may be poisonous. A good manager must have a way of overcoming this. To this end, manager developmental models may be pinpointed to problems or management developmental models may be broader-based. There should be a combination of both types of training, for optimal effect. Competency-based training is more broad-based, giving skills that transcend different situations. Assessment and development centres give pinpointed advice and training for certain situations. Another model is the multi-rater feedback. This means that there is assessment from the people who know the manager best, and the manager also does a self-assessment. These different models have different implications for the globalization challenges, but when used in conjunction with one another, especially the competency-based model with the assessment and development centre model, the manager would have the best training possible to deal with globalization challenges. This paper will outline the management development models. Then it will be talk about globalization, explaining it, and explaining what the challenges with regards to

Northern Ireland Between 1963 and 1972 Essay Example | Topics and Well Written Essays - 2000 words

Northern Ireland Between 1963 and 1972 - Essay Example This particular time period is one of the most important in regards to the entire history of the competing forces between the Unionists and the Nationalists and even in regards to Northern Ireland overall, and in order to understand why the British government was so ineffective during this time, there are several key issues that need to be discussed in regards to this matter. By addressing and examining different people's points of view, as well as integrating somewhat of a personal opinion, we will be able to not only answer the argument of why the British government was so ineffective in this regards, but also the things that they should and could have done in order to best mend relations between these competing forces. Furthermore, we will be addressing the issue of why there was only a political initiative being tabulated after all of this, in the year 1973, and why it was not done before this, as it certainly should have been. This is what will be dissertated in the following. Between the years of 1963 and 1972, there was much turmoil that took place in Northern Ireland, particularly in regards to the competing forces of the Unionists and the Nationalists. ... The Troubles is a term which is used to basically describe the era that is in discussion here, however the Troubles actually initialized in the early 1920s. It is a term which is used to describe "the latest installment of periodic communal violence involving republican and loyalist paramilitary organizations, the Royal Ulster Constabulary (RUC), the British Army and others in Northern Ireland from the late 1960s until the late 1990s ending with the Good Friday Agreement on April 10, 1998".2 Although the Troubles are considered as having truly initialized during the late 1920s, they really did not become acknowledged as to have had begun until the year 1968, when there was widespread rioting and public disorders all over Northern Ireland that had broken out at the marches of the Northern Ireland Civil Rights Association (NICRA). This was one of the main times when the British government should have stepped in and really done something to arbiter these competing forces however they in a sense basically stood by and did nothing. There are a few different reasons that can be used to explain why this is, and one in particular is the fact that they were afraid. Basically, although the Nationalists (Catholics) made up the majority of the population even at that time, it was the Unionists (Protestants) who tended to be richer and more powerful, however when the NICRA group ended up launching a peaceful civil rights campaign in the year 1967, they were "seeking a redress of Catholic and Nationalist grievances within Northern Ireland. Specifically, they wanted an end to the gerrymandering of electoral constituencies that produced unrepresentative local councils (particularly in Derry City) by

Investment Essay Example | Topics and Well Written Essays - 1500 words

Investment - Essay Example Shareholders are the biggest players in any investment and their attitudes towards risks cannot be ruled out. Modern portfolio theory fails to incorporate the needs of all shareholders and uses a single set of shareholders resulting in an unrealistic indifference curve in the modern world. A period of 60 years calls for appropriate adjustments to the practical aspects of the theory. However, the modern portfolio is anchored in a single time period that is used to risks and returns scrutiny. Financial managers are assessed through a series of successive time periods as opposed to the proposition of a single period from modern portfolio theory. Additionally, a single period cannot be used for any meaningful predictions on returns. Therefore, Modern portfolio theory does not cover all the components required to come up with investment strategies for risk reduction. Investing in Apple and Microsoft shares on an equal basis is misguided because the companies have different financial prospects. Microsoft has a higher growth potential than Apple. The 50/50 basis would create a tolerance risk, but it would not realize much returns when compared to when clients invested more money in Microsoft than Apple. The valuation and expected growth for Microsoft will grow considerably because of the popularity of its operating systems and smartphones worldwide (Tilson and Heins, 2011). The clients should also track the stock prices of both companies to check earnings per stock in the last five years. EMH suggests that an investor should assess both historic and current patterns of share prices. Additionally, technical analysis would allow the clients to track share price movements for each company. An increase in the shares prices of either Apple or Microsoft should be reflected in the way they invest their lottery jackpot. Therefore, based on the potential o f growth for Microsoft and Apple’s share price performance, a 70/30 investment in favor of Microsoft would
