Biography of Diane Nash, Civil Rights Leader

Biography of Diane Nash, Civil Rights Leader Diane Judith Nash (born May 15, 1938) was a key figure in the US Civil Rights Movement. She fought to secure voting rights for African Americans as well as to desegregate lunch counters and interstate travel during the freedom rides.   Fast Facts: Diane Nash Known For: Civil rights activist who cofounded the Student Nonviolent Coordinating Committee (SNCC)Born: May 15, 1938 in Chicago, IllinoisParents: Leon and Dorothy Bolton NashEducation: Hyde Park High School, Howard University, Fisk UniversityKey Accomplishments: Freedom rides coordinator,  voting rights organizer, fair housing and nonviolence advocate, and winner of the Southern Christian Leadership Conferences’ Rosa Parks AwardSpouse: James BevelChildren: Sherrilynn Bevel and Douglass BevelFamous Quote: â€Å"We presented Southern white racists with a new set of options. Kill us or desegregate.† Early Years Diane Nash was born in Chicago to Leon and Dorothy Bolton Nash during a time when Jim Crow, or racial segregation, was legal in the U.S. In the South and in other parts of the country, blacks and whites lived in different neighborhoods, attended different schools, and sat in different sections of buses, trains, and movie theaters. But Nash was taught not to view herself as less than. Her grandmother, Carrie Bolton, particularly gave her a sense of self-worth. As Nash’s son, Douglass Bevel, recalled in 2017: â€Å"My great-grandmother was a woman of great patience and generosity. She loved my mother and told her no one was better than her and made her understand she was a valuable person. There’s no substitute for unconditional love, and my mother is just really a strong testament to what people who have it are capable of.† Bolton often took care of her when she was a small child because both of Nash’s parents worked. Her father served in World War II and her mother worked as a keypunch operator during wartime.   When the war ended, her parents divorced, but her mother remarried to John Baker, a waiter for the Pullman railroad company. He belonged to the Brotherhood of Sleeping Car Porters, the most influential union for African-Americans. The union gave workers higher pay and more benefits than employees without such representation.   Her stepfather’s job afforded Nash an excellent education. She attended Catholic and public  schools, graduating from Hyde Park High School on Chicago’s south side. She then headed to Howard University in Washington, D.C., and, from there, to Fisk University in Nashville, Tennessee, in 1959. In Nashville, Diane Nash saw Jim Crow up close.   â€Å"I started feeling very confined and really resented it,† Nash said. â€Å"Every time I obeyed a segregation rule, I felt like I was somehow agreeing I was too inferior to go through the front door or to use the facility that the ordinary public would use.†Ã‚   The system of racial segregation inspired her to become an activist, and she oversaw nonviolent protests on the Fisk campus. Her family had to adjust to her activism, but they ultimately supported her efforts. A Movement Built on Nonviolence As a Fisk student, Nash embraced the philosophy of nonviolence, associated with Mahatma Gandhi and the Rev. Martin Luther King Jr. She took classes on the subject run by James Lawson, who’d gone to India to study Gandhi’s methods. Her nonviolence training helped her lead Nashville’s lunch counter sit-ins over a three-month period in 1960. The students involved went to â€Å"whites only† lunch counters and waited to be served. Rather than walking away when they were denied service, these activists would ask to speak with managers and were often arrested while doing so.  Ã‚   Four students, including Diane Nash, had a sit-in victory when the Post House Restaurant served them on March 17, 1960. The sit-ins took place in nearly 70 US cities, and roughly 200 students who took part in the protests traveled to Raleigh, N.C., for an organizing meeting in April 1960. Rather than function as an offshoot of Martin Luther King’s group, the Southern Christian Leadership Conference, the young activists formed the Student Nonviolent Coordinating Committee. As a SNCC co-founder, Nash left school to oversee the organization’s campaigns. Sit-ins continued through the following year, and on February 6, 1961, Nash and three other SNCC leaders went to jail after supporting the â€Å"Rock Hill Nine† or â€Å"Friendship Nine,† nine students incarcerated after a lunch counter sit-in in Rock Hill, South Carolina. The students would not pay bail after their arrests because they believed paying fines supported the immoral practice of segregation. The unofficial motto of student activists was â€Å"jail, not bail.† While whites-only lunch counters were a big focus of SNCC, the group also wanted to end segregation on interstate travel. Black and white civil rights activists had protested Jim Crow on interstate buses by traveling together; they were known as the freedom riders. But after a white mob in Birmingham, Ala., firebombed a freedom bus and beat the activists on board, organizers called off future rides. Nash insisted they continue. â€Å"The students have decided that we can’t let violence overcome,† she told civil rights leader the Rev. Fred Shuttlesworth. â€Å"We are coming into Birmingham to continue the freedom ride.†Ã‚   A group of students returned to Birmingham to do just that. Nash began to arrange freedom rides from Birmingham to Jackson, Mississippi, and organize activists to take part in them. Later that year, Nash protested a grocery store that would not employ African Americans. As she and others stood on the picket line, a group of white boys started throwing eggs and punching some of the protesters. The police arrested both the white attackers and the black demonstrators, including Nash. As she had in the past, Nash refused to pay bail, so she remained behind bars as the others went free.   Marriage and Activism The year 1961 stood out for Nash not only because of her role in various movement causes but also because she got married. Her husband, James Bevel, was a civil rights activist, too.   Marriage didn’t slow down her activism. In fact, while she was pregnant in 1962, Nash had to contend with the possibility of serving out a two-year prison sentence for giving civil rights training to local youth. In the end, Nash served just 10 days in jail, sparing her from the possibility of giving birth to her first child, Sherrilynn, while incarcerated. But Nash was prepared to do so in hopes that her activism could make the world a better place for her child and other children. Nash and Bevel went on to have son Douglass.   Diane Nash’s activism attracted the attention of President John F. Kennedy, who selected her to serve on a committee to develop a national civil rights platform, which later became the Civil Rights Act of 1964. The next year, Nash and Bevel planned marches from Selma to Montgomery to support voting rights for African Americans in Alabama. When the peaceful protesters tried to cross the Edmund Pettus Bridge to head to Montgomery, police severely beat them.   Stunned by images of law enforcement agents brutalizing the marchers, Congress passed the 1965 Voting Rights Act. Nash and Bevel’s efforts to secure voting rights for black Alabamians resulted in the Southern Christian Leadership Conference awarding them the Rosa Parks Award. The couple would divorce in 1968.   Legacy and Later Years After the Civil Rights Movement, Nash returned to her hometown of Chicago, where she still lives today. She worked in real estate and has participated in activism related to fair housing and pacifism alike.   With the exception of Rosa Parks, male civil rights leaders have typically received most of the credit for the freedom struggles of the 1950s and ’60s. In the decades since, however, more attention has been paid to women leaders like Ella Baker, Fannie Lou Hamer, and Diane Nash.   In 2003, Nash won the Distinguished American Award from the John F. Kennedy Library and Foundation. The following year, she received the LBJ Award for Leadership in Civil Rights from the Lyndon Baines Johnson Library and Museum. And in 2008, she won the Freedom Award from the National Civil Rights Museum. Both Fisk University and the University of Notre Dame have awarded her honorary degrees. Nash’s contributions to civil rights have also been captured in film. She appears in the documentaries â€Å"Eyes on the Prize† and the â€Å"Freedom Riders,† and in the 2014 civil rights biopic â€Å"Selma†, in which she’s portrayed by actress Tessa Thompson. She is also the focus of historian David Halberstams book â€Å"Diane Nash: The Fire of the Civil Rights Movement.†

Change mangement in Qantas Essay Example | Topics and Well Written Essays - 750 words

Change mangement in Qantas - Essay Example This section will illustrate the specific principles through the application of the KT approach of project management. This approach will split the project into three basic areas, in which communication occurs over all levels as shown below; The KT process will help Qantas in the analysis of implementation of goals via a systematic process of decision-making. It will apply in this case because it aids in achievement of improved satisfaction of customers, increasing sales, and the elimination of problems in sales (Biech, 2010: p44). The first step is analysis, where they will come up with rough goals to improve business like marketing of new products to clients. The management team will collect information from market data, databases, competitors, and customer surveys and sort through it to collect information accurately since this data forms assumptions on which all KT steps in the future will be undertaken. The second step is the strategy where Qantas, using all relevant data will h ave its management craft cost effective plans that accomplish the goals. They will take into consideration all barriers that may hinder the objectives, scope and types of products and services offered, new business sources, how to attain competitive advantage, as well as goal timeframes (Biech, 2010: p45). Following the strategy creation, a project design will be created and presented to the owner. In the third step, Qantas will consider the designs presented by the managers, as well as have the managers pitch strategies in the strategy session. Qantas, using the management team, will select the best strategy and come up with a master plan. This will include the project’s purpose, its schedule, project stages, and resources that are needed to meet the objectives (Biech, 2010: p45). Following this, the next phase is the implementation of the master plan through assigning various tasks and training the management in the fulfillment of roles. The KT process is emphatic on hands- off approach, which requires little interference where managers and employees only get required skills needed to complete objectives in the plan. Qantas should also ensure that the employees are constantly informed on the progress of the plan, only becoming active in the plan implementation when deadlines are not met. The final step is review, where Qantas while using the KT process need to review whether the plan is working after it is implemented since the plans are not necessarily considerate of all relevant variables in meeting the goals of the business (Biech, 2010: p47). As the project concludes, they should update the master plan to improve on the results. Should the project fail because of inaccurate research, the plan should be scrapped altogether and more time focused on the KT process’ analysis step. It is also opined that that Qantas used the popular Kotter’s 8 steps model as it is displayed in figure 2: Figure 2 steps to successful change The first step th ey would take would be creating a sense of urgency since everyone at Qantas will have to be behind the change and believe in it. They should identify potential threats with concurrent scenarios of possibilities in the future (Cameron & Green, 2012:

May be on any philosopher or logician (e.g., Aristotle), any pair of philosophers or logicians (e.g., Aristotle and Frege), an - Essay Example The Academy in Athens was the first institution in the Western World devoted to research and instruction in philosophy as well as other sciences. Plato’s works delve into political events and intellectual movements of his time while raising profound questions and tackling them in s richly suggestive and provocative manner that educates readers of nearly every period. As such, Plato’s works has been used as teaching material in varied subjects such as philosophy, logic, ethics, rhetoric as well as mathematics. In this regard, Plato along with Socrates and Aristotle played a crucial role in influencing the foundation of Western philosophy and Science. In essence, Plato expressed a sense of self-consciousness in regards to how we ought to conceive philosophy, its proper scope and ambitions. This paper seeks to discuss Plato’s contributions to the field of philosophy. In this regard, the paper discusses the biography of Plato and addresses his work in the field of ph ilosophy. ... In regards to Diogenes Laertius account, Plato derived the name Plato from the breadth of his expressiveness while his wrestling coach as well gave him that name in light of his stature. Plato had the quickness of mind and modesty as a young boy while his hard work and love of study made him a student of Socrates. Prior to meeting with Socrates, Plato had received instructions in grammar, music as well as gymnastics while he was as well acquainted with the Cratylus and the Heraclitean doctrines. After the death of Socrates, Plato traveled in Italy, Sicily, Egypt and Cyrene. He returned to Athens while at the age of forty and founded the Academy in Athens, one of the earliest known formal institutions of higher learning in Western Civilization. The Academy in Athens schooled many intellectuals with the most prominent one being Aristotle. Plato later delved into politics by associating in the politics of the city of Syracuse. Plato died in 347 BC while the details of his death remain s canty. The widely acclaimed accounts detail that he died in his sleep. In essence, the biography of Plato remains scanty in many areas owing to the lack of proper documentation of events during his era. Plato’s philosophical contributions Persistent themes One of the most persistent themes in Plato’s philosophical work is the relationship between a father and a son. Plato pays particular interest to the question whether the interests that a father has in relation to his son have profound influence on how well the son turn out. The factor influencing Plato’s concern in this theme is the fact that in ancient Athens, the social identity of a boy emerged from the social identity of his family. Plato differs from his mentor, Socrates, who mocks the

Public health international perceptives Essay Example | Topics and Well Written Essays - 4000 words

Public health international perceptives - Essay Example The foundation of public health as advanced by the Canadian government and societies agitate for a healthy society and its people; under the Ottawa charter for health promotion, health promotion is defined as the continuous effort to achieve health for the society. This effort supersedes the basic desires of making health information available to the public, and involves the empowerment of citizens to control their health and to work towards improving their health. In the promotion of public health, the Canadian government has ensured continuous focus on the entire population and sub-populations that may share health problem or concerns. This is based under the ‘population of interest’ and the ‘population at risk’ policy (Taske et al, 2005). In the implementation of the public health promotion program, the Canadian government has established bodies that conduct annual and regular assessments of the health status of the entire population. This is carried out through a community health assessment process facilitated by community health organizations and workers. Public health also has major determinants that must consider in any program that seeks to promote and raise the standards of public health. The public health agency of Canada has a broad classification of health determinants that provides guidance to any process that seeks to uplift the health of the population. The health contributing factors include the income and social status of the population and the presence of social support networks; in addition, education and literacy level of the population are parameters of public health. The social environment, employment status, physical environment and personal health practices are also important health determinants that shape any public health promotion program in the country (Hills, 2004). Primary prevention of new infections is an important public health variable that must also be considered before initiating any health promotion programs. This is well defined and coordinated in Canada under the public health promotion acts. In primary prevention, the source of the infection is dealt with well before any threat of infection is reported. This prevents any infection from occurring and helps in the reduction of health and social inequalities in the society. The development of public health across the world was a continual process that was facilitated majorly by the high level of new diseases that were affecting the entire population. Diseases such as tuberculosis, sexually transmitted infections, HIV/AIDS and a number of other highly contagious diseases necessitated the intervention of different governments. The development of public health in Canada occurred in a well coordinated and progressive manner necessitated again by the high emergence of new infections and endemics. The country today has legal bodies that are mandated to ensure the promotion health and the prevention of diseases (ACPHHS, 2005). The co untry has a number of measures that it has adopted over the years to ensure public health promotion and development in the country. To achieve the mandates set forward for these institutions, the public health sectors of Canada have also initiated a number of partnership programs aimed towards ensuring the high cost of maintaining a healthy society and country is shared. The major players

How Reliable is Eyewitness Testimony?

How Reliable is Eyewitness Testimony? This essays attempts to reach a conclusion regarding eyewitness testimonies and the extent of its reliability. This was done by identifying factors in three different processes stages. The acquisition stage is the period where the witness experiences the event. The retention stage is the period between the time the event ends and the time the witness are asked for a recount or questioned about the event. The retrieval stage is the period where the witness is providing information from their recall. During the acquisition stage, research regarding exposure time, estimation of factors concerning the event (for example, time), violence of the event, weapon focus and witness stress was analysed. During the retention stage, research regarding post-event information, introduction of conflicting information and introduction of misleading information was analysed. During the retrieval stage, research regarding method of questioning, leading questions and a case study of an actual event was analysed. Experiments and case studies regarding these factors were then evaluated to weigh the impact that it had on eyewitness testimony. In conclusion, it was found that experiments regarding eyewitness testimony hold little evidence to support its reliability but there are also some findings that dispute this. Thus, it was concluded that it is reliable only to a small extent though it can be highly accurate under certain conditions. Applications of this conclusion includes jurors being more aware of the factors regarding eyewitness testimony and taking into account when deciding on a verdict especially if the main evidence is based solely on eyewitness recounts. Word Count: 252 words Introduction Eyewitness testimony is usually a verbal account given by an individual who has experienced an event, typically of a crime. Eyewitness testimony relies heavily on the capability of the individuals to accurately recount the event. In a trial, the jury is most often persuaded due to the statement(s) of the witnesses. Also, in cases where little material evidence can be collected, eyewitnesses are the focus for reaching a verdict. It has been argued that because testimonies are largely based on fallible memory which can be influenced by a variety of factors, it should not be depended upon. The contention of this essay is to identify and evaluate the extent of accuracy of this claim by identifying and evaluating factors that affect memory and by reviewing experiments and case studies to reach a conclusion on this matter. Memory and thus eye-witness reliability has become an issue of importance due to the high percentage of errors in identifying and prosecuting accused individuals. Thus, the reliability of eyewitness testimonies and impact on trials should be reviewed. Memory is defined as a kind of repository in which facts (information) may be retained over some period of time (Loftus, 1979). According to the Atkinson and Shiffrin model of memory storage (1971), memory is made up of three different types of information stores, each with different duration, capacity and function. The first is Sensory Memory. This type of store lasts for the spilt second when individuals collect information from their sensory systems and preserves information in its original sensory form. The sense organs are limited in their ability to store information about the world in an unprocessed way for more than a second. Thus, information is filtered through or selected by attention for further memory processing into the next type of memory store. This process of experiencing and filtering information is called acquisition. The next memory store is Short-term memory allows individuals to retain information long enough to be used and lasts approximately between 15 to 30 s econds. Miller (1956, cited in Weiten, 2005) proposed that Short-term Memory had a capacity of about 7 chunks of information. If certain actions are carried out, the information will be transferred to the last type of memory store, Long-term Memory. Long-term Memory provides retention of information which can last between minutes to a lifetime and has a limitless capacity. The process of information deposited in the short-term and long-term memory store is called retention. Information is constantly being transferred between these stores. When witnesses are asked to give recount of what they witnessed, information is taken from the long-term memory store and this process is called retrieval. Events during these three processes may affect the quality of the eyewitness testimony. During the acquisition process information may not have been perceived in the first place, information may be forgotten or interfered during the retention process or information may be inaccessible during questioning or during the retrieval process. Analysis of Factors that may affect Eye-witness Testimony during the Acquisition Process During the acquisition process, there are a number of factors that can affect an eyewitness report of an event such as exposure time or stress. This can be divided into event factors and witness factors. This section of the essay will evaluate the effect of these factors on the reliability of eyewitness testimony. Exposure time to the event or object of focus is an event factor. Laughery et al (1971, cited in Loftus, 1979) tested subjects on their recall based on the exposure time to a picture, showed one at a time of different positions of a human face. Two Caucasian male target faces were used, one with fair-colored hair and complexion with glasses and another with a darker-colored hair and complexion without glasses. The independent variable is the time the subjects viewed the pictures, which ranged from ten seconds to thirty-two seconds. The subjects were them asked, approximately eight minutes after exposure to identify the target within a series of 150 slides of human faces. The dependant variable is the accuracy of the subjects recall. Fifty-eight percentof the subjects who viewed the pictures for thirty-two seconds correctly identified the target but only forty-seven percent of the subjects who viewed the pictures for ten seconds correctly identified the target. This suggests that the more time a witness has to view the target, the more accurate their recall will be. This research is significant as it is very scientific and precisely tested a specific variable that affects memory and recall. Although this is so, it was also conducted in an artificial environment and thus, has low ecological validity. The research may also contain cultural and gender bias as it only tested for Caucasian males as the target. Thus, its application to targets of different cultures or gender is questionable. Estimating factors such as time, speed or distance is often asked of eyewitnesses. This involves perceiving the event and accurately inferring information from it. Marshalls (1966, cited in Loftus, 1979) experiment tested subjects estimation of time. Four hundred and ninety-one subjects watched a forty-two second film and a week after they had given their written and oral reports of the event, they were questioned as to the duration of the event. On average, subjects gave an estimate of about ninety seconds. The results show that witnesses can inaccurately estimate certain factors of an event. Although the results are significant, the study was conducted in a controlled environment which gives it little ecological validity. To further assess the accuracy of this study, an additional study that can be considered is Buckhout et al. (1975, cited in Loftus, 1979)s study on the effects if eyewitness testimony in a real situation by staging an attack where a student attacked a professor in front of 141 witnesses. The attack lasted for thirty-four seconds but when interviewed later on, the average estimate of the duration of the event was eighty-one seconds, almost twice the actual time. This study supports Marshalls study which shows that there is a tendency for witnesses to overestimate the duration in an event. This is significant in most cases, especially for cases of self-defense where the time between the attack and the retaliation is very significant in the categorization of the action. Another event factor is the violence of the event. A research done by Clifford and Scott (1978, cited in Loftus, 1979) investigated the ability of eyewitnesses to perceive violent and non-violent events. Forty-eight subjects with equal number of men and women watched either one of two tapes. In the non-violent version, the characters were involved in a verbal exchange and weak restraining movements. In the violent version, one of the characters physically assaults another character. In an effort to be even, the start and end of the tapes were manipulated to be identical. It was found that regardless of gender, the level of recall is significantly lower for those who viewed the more violent tape. It is inferred that this is due to the greater amount of stress that is produced in response to the violent event. This shows that eyewitness testimony of a violent event should be considered with the possibility of a higher rate of inaccuracy. Though the results are significant due to the hi gh reliability of the scientific method used, it also lacks ecological validity as it was conducted in an artificial environment where witnesses do not actually experience the event. An event factor that is linked to the witness factor, stress, is weapon focus. Easterbrook (1959) found that under high stress, individuals tend to concentrate more on a few features of their environment and less attention to other features. Weapon focus is where a crime victim is faced with an assailant who is brandishing a weapon. This rises the stress level of the crime victim and thus, they will only concentrate on a few features, mainly the weapon and will have trouble recollecting other factors such as the assailants features. Loftus et al (1987) tested this with an experiment where thirty-six students were showed a series of slides which showed one of two scenarios at a fast food restaurant. Half the subjects saw a customer pointing a gun at the cashier while the other half, the control group saw a customer handing the cashier a check. A part of the experiment tested the memory of the students based on a series of seven questions on the customer. It was found that the level of accuracy of the weapon group was fifty-six percent while the level of accuracy for the control group was sixty-seven percent. As the results show that the accuracy level of the weapon group is lower than the control group, this is highly significant in showing that eye-witnesses acquisition process might be seriously hampered by the presence of a weapon. The results of the experiment are highly valid as it was conducted in a controlled environment which allowed a direct cause and effect outcome. While this is so, the participants did not experience the event and thus their response may be different to an actual witness which means that the experiment lacks ecological validity. During an event, stress is a witness factor that should be taken into account. This refers to the level of stress or fear that a witness experiences which may influence their perception during the acquisition process of the event. A simulated case study done by Berkun (1962, cited in Loftus, 1979) placed army recruits in a stressful situation. They were isolated with the exception of a telephone link. Then, they were told that they were in danger to induce anxiety and were required to repair a broken radio by following a series of complicated instructions. It was found that the high level of anxiety impaired performance of the subjects. As this case study was conducted during a period of different ethical standards than today, there are ethical implications to be considered. Nevertheless, the results of this case study significantly support the Yerkes-Dodson law (1908, cited in Green) which states that emotional arousal facilitates learning and performance up to a point after which t here is a decrement. This can be applied to eyewitnesses who experience stress. Their senses may be stimulated but after a point, their acquisition process will be negatively affected. Although this is so, this case study has only looked at male soldiers, thus when applied to the general population, it lacks ecological validity. Analysis of Factors that may affect Eye-witness Testimony during the Retention Process Eye-witnesses are being tested on their retention of information from their Long-term Memory. Because retained information and thus, memory is being transferred between memory stores, it is possible that it can be influenced, enhanced or even distorted during or in between transfers. This section of the essay will focus on the numerous researches that have been carried out to investigate the accuracy of this or the extent of the influence that may occur. After an event occurs, sometimes witnesses discuss what they saw with each other and the information that is exchanged can result in an enhancement of memory in the form of modification or addition. An experiment was conducted by Loftus (1975) on one hundred and fifty participants. They were showed a film of a car crash where a car failed to stop at a stop sign and turned right to enter traffic, causing a five-car collision. After the film which lasted for less than a minute, participants were asked a series of ten questions. Half of the participants were asked about the stop sign in the first question while the other half were asked about the right turn. All other questions were the same. The independent variable here is the first question and the dependant variable is the last question which asked participants if they remembered seeing a stop sign. Loftus found that there was a higher percentage of participants who recalled seeing a stop sign if the first question related to a stop sign than the control group, fifty-three percent and thirty-five percent respectively. This shows that by mentioning an object, there is a higher chance of it being recalled. The results are highly significant as it was calculated using precise results with a specific variable tested. It can be argued that the experiment lacks ecological validity as it was conducted in an artificial environment but this allowed a specific variable to be tested which would have been impossible with a case study. As demonstrated by this experiment, eye-witnesses memory may be influenced by post-event information that they receive and thus, the more information that the witness is exposed to after the event, the higher the chance that their memory might be compromised. A modification to the previous variable is the question as to what happens when a witness learns new information which is different from what they experienced. Loftus (1975) conducted an experiment where forty participants were shown a three-minute video which involved a group of eight demonstrators noisily interrupting a lecture. The participants then had to answer a series of twenty questions. All the questions for the participants were identical except for one. Half of the participants were asked, Was the leader of the twelve demonstrators who entered the classroom a male? and the other half were asked, Was the leader of the four demonstrators who entered the classroom a male? All questions had to be answered with a yes or no. A week later, participants had to answer another set of questions. The critical question was How many demonstrators did you see enter the classroom? It was found that participants who previously answered the question with the word twelve reported an average of 8.9 demonstrators while the other half reported an average of 6.4 demonstrators. It can be argued that this experiment lacks ecological validity as it was conducted in an artificial environment and that participants only viewed the event and did not actually witness it. The results may not be fully applicable to the general population. Although this is so, the controlled environment showed a direct cause and effect of a specific variable. The results of this experiment can be applied to eye-witness testimony where witnesses may be mislead in their testimony as their memory might be compromised by the introduction of conflicting information. Similar to the experiment above is an experiment conducted by Loftus and Zanni (1975, cited in Hill, 1998) which was a modification of the original Loftus and Palmer research. The aim of the experiment was to investigate the effect of adding post event information on memory. Participants were shown a film of a car accident after which they had to answer a series of questions. Half of the participants were required to answer, Did you see the broken headlight which implied that there was a broken headlight while the other half were asked, Did you see a broken headlight which only required participants to recall if it was there. It was found that half of the participants, who were asked using the word the, incorrectly reported seeing a broken headlight. As most of the other variables were controlled in the experiment, and only a specific variable was changed, the results signify that memory can be modified by post event information. It can be argued that the participants did not experie nce the incident and thus the experiment lacks ecological validity when applied to actual witnesses but as a specific variable was examined, it can be concluded that the cause and effect was to a large extent connected. This experiment shows that eyewitnesses may be influenced by post event information which may negatively affect their account. McCloskey and Zaragaza (1985) also conducted experiments concerning the effect of misleading post event information on participants. After watching a series of slides depicting an event, participants received a narrative of the event. Participants in the mislead condition will receive a narration with receive the narrative with misleading information about a detail of the event, a hammer was referred to as a screwdriver instead while the control group werent provided details of the specific event. Participants then had to answer a series of questions about the event. The critical question concerning the tool had the original item as an option (hammer) and a new item (wrench). It was found that accuracy for the control group was seventy-five percent and seventy-two percent for the mislead condition group. The fact that there was little difference between the two groups points to the idea that misleading post event information does not distort memory of an event. This experiment suppor ts the validity of eyewitness testimony and due to the controlled setting; the results are highly valid though it lacks ecological validity. Analysis of Factors that may affect Eye-witness Testimony during the Retrieval Process Most evidence from eyewitnesses are a result of their accounts of the event. This involves the retrieval process of information from their long term memory store. This section of the essay aims to analyse and evaluate research conducted in relation to the techniques of retrieving information from eyewitnesses such as question wording or method of questioning. This is to evaluate the extent of influence of such techniques on the reliability of eyewitness accounts and in relation, memory. The method of questioning during the retrieval process plays an important role in the accuracy of eye-witness testimony as investigated by Lipton (1977, cited in Wells, 1978). Lipton conducted an experiment where participants watched a film of a murder in a courtroom setting. He found that unstructured testimony which allowed free recall resulted in ninety-one percent accuracy. This is a significant value as compared to other types of questioning such as open ended questions with eighty-three percent accuracy, leading questions with seventy-two percent accuracy and multiple choice questions with fifty-six percent accuracy. These results show that the type of questioning that the witness is subjected to affects the accuracy of their recount. When applied to trial testimonies, jurors should take into account the type of questioning to predict or get an idea of the level of accuracy of the testimony. Though conclusive to a certain extent, the experiment lacks ecological validity as the participants did not actually experience the event, merely perceive it but as it is a controlled environment, the reliability of the cause and effect factors is high. Loftus and Palmer (1974 cited in Hill, 1998) carried out an experiment to investigate the effect of leading questions on the accuracy of participants in recalling a car crash. Fourty-five participants were separated into seven groups and each group watched a video of traffic accidents. The videos lasted from five to thirty seconds. After watching the video, participants had to give an account of what they had just seen. The independent variable is the question About how fast were the cars going when they hit each other?. The word hit is replaced with the words smashed, contacted, bumped and collided for different groups. The participants answer as to the estimate of the cars speed is the dependant variable. Loftus and Palmer found that the mean estimate of speed for more aggressive words such as smashed is higher than less aggressive words such as contacted. The results are highly significant, p Contending the results of this experiment is Yuille and Cutshalls (1986) case study of a real life event. 13 participants were interviewed using Loftus and Palmers (1974 cited in Hill, 1998) technique in their recall four to five months after witnessing an attempted robbery in daylight where one individual was killed and another, seriously wounded. It was found that there was a very high level of similarity between the accounts given by the witnesses, the accounts did not alter in response to leading questions and that the witnesses were able to recall the event in detail. Additionally, accounts of those who were more distressed had a higher accuracy level. These results are different to Loftus and Palmer (1974 cited in Hill, 1998). The eye witnesses did not alter their accounts greatly in response to leading questions. As this is a case study, it holds high ecological validity unlike laboratory experiments. Although this may be true, Yuille and Cutshalls case study was of an event t hat was relatively traumatic event and was viewed in ideal conditions. Most incidents do not mirror this setting. Also, it was an investigation of only one case study. Hence, the application of these findings is debatable when applied to general eye witness testimonies. Conclusion This essay evaluated the extent of accuracy of the claim that eyewitness testimony should not be depended upon. This was done by focusing on the different factors that can affect human memory, and in relation, eyewitness testimony as it is fundamentally based on memory. Experiments and case studies related to factors in three different memory stages were identified and evaluated. Research concerning the acquisition process such as exposure time, estimation of factors concerning the event, for example, time, violence of the event, weapon focus and witness stress level during the event was analysed. Results point to a correlation of high levels of inaccuracy when more traumatic factors are included in the event. This is also reflected in research concerning the retention process and the retrieval process although there is some evidence that supports the reliability of eyewitness testimony. Overall analysis criticised the low ecological validity of controlled experiments but also supported the high level of validity that comes with it as it essentially provides a cause and effect relationship between specific variables tested. Case studies were found to be very specific with regards to certain factors, which leads to a debate about their general application. Since experiments are only replications of real-life events, it cant be fully taken as the actual process . This may have some influence on the results obtained as it can be argued that the participants are not really experiencing the event, thus essential factors like, atmosphere, or even interest in the event may be compromised. In this manner, results of case studies hold a higher level of reliability. As indicated by the numerous researches on different factors during the process of collecting, processing and retrieving information from memory, eye witness testimony is reliable only to a small extent. Under such fallibility, it can be questioned if eyewitness testimony should be relied on at all. Though eyewitness testimony has been proved accurate in a number of researches, the amount of investigations concluding on the fact that it is highly imperfect far outweighs it. Though a large number of researches do not support the reliability of eyewitness testimony, there is also evidence to support it like Yuille and Cutshalls (1986) case study. This suggests that although eyewitness testimony can be unreliable, under certain conditions, it is highly accurate. Implications for application of the analysis in this essay could include jurors being more wary of eyewitness testimony and the conditions relating to it when deciding upon a verdict. Further research could include more case studies to increase the ecological validity of the theories produced by experiments analysed in this essay. References Atkinson, R. C. Shriffin, R. M.

Geography of Cuba Essay -- Essays Papers

Geography of Cuba The geography of Cuba is very diverse, with large mountain ranges spanning the western and south central regions, and a beautiful 2,320 mile coastline that boasts white, sandy beaches to the north. The semitropical climate of Cuba supports lush, agricultural fields in which many species of plants and animals thrive. The main island of Cuba is about 40,543 sq. miles, and Cuba's Isla de la Juventud (Island of Youth) covers about 1,180 sq. miles. Also part of the Republic are four sets of small archipelagos: the Sabana, the Colorados, the Canarreos and the Jardines de la Reina. The main type of soil found in Cuba is red clay, along with some sand and limestone hills. A surprising three quarters of Cuba's land is fertile countryside and is readily accessible to many harbors. Cuba has a unique advantage over the other Carribean islands because of its accessibility to harbors, which allows for the transport of agricultural goods easily and efficiently to foreign markets. ...

Street Art Legalization

â€Å"Imagine a city where graffiti wasn't illegal, a city where everybody drew whatever they liked. Where every street was awash with a million colours and little phrases. Where standing at a bus stop was never boring. A city that felt like a party where everyone was invited, not just the estate agents and barons of big business. Imagine a city like that and stop leaning against the wall – it's wet. † (Banksy 85) Graffiti is a global form of expression that is untamed but uses similar methods as advertisements, yet is illegal in most cities.Street art is a way of spreading your name or message, just like a company puts up billboards to get their product to their demographics. Graffiti and Street art in general are just terms for the urban art form of scribing or painting on public space with a message or name. The culture of graffiti is very hard to control since all of the tools needed are in the average person’s home already. Street-Art should be legalized bec ause it is less destructive than advertisements and they are displayed in the same methods.Tagging is the first step in becoming a graffiti writer, It is an artist’s baby steps in to the urban art form known as graffiti. A tag in graffiti is an artist’s signature. It represents who you are, where you’re from, and why you write. As the graffiti writer â€Å"Earsnot† said, â€Å"Tagging is like a timeline† you can follow the tags and see where the person has been that day just by the color of their ink (‘Infamy’) â€Å"The term ‘graffiti’ derives from the greek graphien which means to write† The current meaning of graffiti came to being because that is what the drawings and â€Å"marks found on ancient Roman architecture†(Phillips Par 1).Writers for the majority will not sign their real names; they instead use nicknames, codes, or symbols within complicated lettering systems† (Phillips Par 4). Graffiti us ually gets a bad reputation because people see the beautiful murals and wonder why the same artists create ugly scrawl. Graffiti comes in many forms and people really need to understand that. Since there aren’t any two writers at the same level, and all writers are at different steps in the art form. You cannot simply pick up a paint can and created perfect typography and detailed illustrations, no matter what your level of art is in any medium. The grimy, dirty, dripping tag signature comes from the same hands as the enormous multicolored murals† (Gastman 127). Many people say why do graffiti artists tag when they can just do murals. â€Å"Some people want to make the world a better place. I just want to make the world a better-looking place. If you don’t like it, you can paint over it! † (Banksy par 15), in this quote the London street-artist Banksy is stating that he doesn’t care if you paint over or buff his work since he is just going to keep d oing it. So the government is just wasting paint and money.Street Art is a form of graffiti that uses the same way of portraying the artists work but with different tools and mediums. One of the most common means of getting street-art up is with the use of stencils. Where the artist will take cardboard or plastic and make a cutout into the material, usually displaying and icon or figure. Another common method of street-art is wheat pasting which where you create a poster sketched or printed on larger paper and then create a glue like substance using cornstarch and some form of an epoxy.Some street-artists and graffiti artists alike will â€Å"sticker-bomb† which is where the either print stickers with a message or use shipping labels with a hand drawn character or tag and they will put them on walls, signs, windows, etc. Since it is a much quicker way than using a marker or a can of spray paint where you might get caught in the act if you are not very quick or in a rather cro wded place. Graffiti is a cultural phenomenon that cannot be controlled. Every culture that currently exists or has existed has had its own form of graffiti.Modern graffiti is thought to have originated during the Greek empire with political ideas and criticism that people would scribe onto the walls since it would be a definite way that the government would see it. Graffiti cannot be pure vandalism because it can be traced to almost every known society. Also graffiti writers cannot be classified as a single type of person, people who write come from every background. â€Å"Graffiti is a cross-cultural phenomena common to every literate society.Within the variable contexts of their production, graffiti personalize de-personalized space, construct landscapes of identity, make public space into private space, and act as promoters of ethnic unity as well as diversity. Graffiti can be understood as concrete manifestations of personal and communal ideologies which are visually striking, insistent, and provocative; as such, they are worthy of the continued attention of art historians, social scientists, and policy makers alike. † (Phillips 9) Graffiti is going to occur whether it’s legal or not.If government legalized graffiti in public space, the overall crime rate would go down because it would not be added into the statistic of crimes that occurred and governments would not have to pay people to buff out the graffiti. Advertisers capitalized on graffiti strategies. Strategies that started to flourish in the early 1980’s in the New York where innovative writers such as â€Å"Cornbread† would do graffiti on subways and later busses. â€Å"You owe the companies nothing. You especially don't owe them any courtesy.They have re-arranged the world to put themselves in front of you. They never asked for your permission, don't even start asking for theirs. † (Banksy 160) As said by Claw â€Å"Im making my stamp and I want it everywhereà ¢â‚¬ ¦ † (‘Infamy') this is exactly what companies are saying when they purchase advertisement space. Advertising and graffiti function on a phenomenological element to arouse the viewer's curiosity. They rely on the sheer amount of coverage and penetration, just as brands do to grow.If you look into a crowd of people on almost every person you see you can recognize the company that created their clothing. They rely on the quality of the delivery to embed themselves into the viewer’s perception. â€Å"Brandalism; Any advertisement in public space that gives you no choice whether you see it or not is yours. It belongs to you. It's yours to take, rearrange and re-use. Asking for permission is like asking to keep a rock someone just threw at your head† (Banksy 160). Society has an impact on artists.In popular culture where advertising is seen thousands of times a day it evokes a desire in people to make there mark on this world. The empty promises of ads get f lipped upside down when a writer realizes they possessed his or her own ‘brand'. The effect of advertising on young children may have been the catalyst for this global art movement. â€Å"The people who run the cities† do not recognize graffiti because they believe nothing has the right to exist unless it makes revenue. But if you just value capital then your belief is insignificant (Banksy 7). 1 year old Coda Explains, â€Å"Basically, when I look around, I see us living in a modern day Babylon, full of temptation, sin, distraction, corruption, injustice, and misguided fools being mentally enslaved. It seems to me the only way to wake people up from this kind of numbness is to destroy what they know: Their business, their places of commerce and their biggest place of gathering, the cities! Put it on their trains, on the lines they take to work, on their rooftops, on their highways, on anything just to make some people realize that culture isn't ost and that, at the ve ry least, a small group of kids is fighting to keep it alive† (Tucker 1). Graffiti should be legal because it is less destructive to people than advertisements and they are displayed in the very similar methods, yet people are shocked to see it. Graffiti approaching them not in a gallery, but on the streets.. One of the main point that I am trying to prove through this paper even though it isn’t mentioned is, why is the government persecuting people trying to create art and shape the way that modern history is unfolding.

Sleep Patterns in Children essays

Sleep Patterns in Children essays This study basically focused on the sleep patterns, sleep disruptions, and sleepiness of school age children. The study was based on sleep patterns of 140 children (72 boys and 68 girls- who were 2nd, 4th, and 6th grade students). This study has significance because sleep plays an important role in child development and is a major component to a childs well being. Many factors can affect the childs sleep-wake measures. For example, family stress, parental age, and parental education. The relationships between sleep problems and a childs well being appeared to be linked together. Sleep problems are among the important clinical symptoms and diagnosed criteria of many emotional disorders such as affective disorders, posttraumatic stress disorder, and anxiety disorders. In the early childhood years, disturbed sleep has been associated with bad temperament. Sleep disruptions have many times been implicated inconsideration with deficit hyperactivity disorder (ADHD) in children. There are clear signs that learning and attention skills can be negotiated by insufficient sleep or sleep disruption. Multiple surveys that have taken place in many different countries, have estimated that 20% to30% of children suffer from sleep disruptions in the first three years of life. The studys main goals were to document: (1) age differences in sleep schedule and sleep quality, (2) sleep disruptions in children evaluated by objective measures and precise definitions, (3) subjective sleepiness and its relationships with objective measures of sleep, and (4) the relationships between objective sleep measures and psychosocial measures. The studys main purpose was to create normative data on sleep-wake patterns of school-age children by using their objective and subjective methods. The results of the study shed light on many new ideas and perspectives. The new set of findings included ...

Essay To Do

Essay To Do Essay To Do Analysis of Blood Alcohol by Gas-Liquid Chromatography Virtual Lab Respectfully Submitted to the Forensic Science Department Abstract The researchers experiment was about the police officers investigation on whether or not John Johnson who had initially been pulled over after being seen crossing the double line on a crowded highway. Johnson was pulled over and alcohol was detected. The officers tested Johnson for alcohol with two field sobriety tests. Which involve standing on one foot for thirty seconds and walking in a straight line heel-to-toe. Johnson failed both tests which led for his blood samples to be tested and his blood alcohol content to be investigated. The researcher found that Johnson was indeed intoxicated and had an EA area of 191 with a peak of 1.7, and PA area of 312 with a peak of 3.2 in the unknown blood. In standard 1 the PA area was 298 with a peak of 3.2. In standard 2 the EA area 82 had a peak of 1.7 while the PA area of 297 had a peak of 3.2. Finally in the researcher’s standard 3 the EA area was 272 with a peak of 1.7 and a PA area of 319 with a peak of 3.2. Table of Contents Introduction Pre-Lab Questions Materials and Methods Results Discussion Conclusion Appendix References Introduction The researchers experiment involved the testing of a suspected drunk driver’s blood alcohol context. Once the sample was taken to the hospital the researchers used a Blood Alcohol by Gas- Liquid Chromatography using an internal standard to test it. Gas chromatography is a process by which a mixture of compounds in volatilized form may be separated into its constituent parts by moving a mobile (gas) phase over a stationary phase (sorbent or liquid phase). The progress of each component through a column is decreased in proportion to the component's affinity for the stationary phase. Each component is detected as it emerges from the column by a flame ionization detector. The components can be identified by their characteristic time required for emergence (retention time) and quantities by determining the ratio of the detector signal strength for the component to the signal strength for a reference compound (internal standard). (Angelos, 2010) In the researchers experiment the researcher applied gas chromatography to the separation of a water-ethanol mixture. This method is often used in the determination of alcohol (i.e. ethanol) in blood or urine. One obvious application is when law enforcement agencies need to determine whether or Not someone is inebriated. In these cases, high sensitivity is required since 0.1% blood alcohol Content is considered to be legally intoxicated in most states. The researchers own determination dealt with higher concentrations (up to 25% by volume) which are more typical of alcohol levels Found in many alcoholic beverages. (Angelos, 2010) Gas chromatography is a powerful and widely used tool for the separation, identification And quantization of components in a mixture. In this technique, a sample is converted to the Vapor state and a flowing stream of carrier gas (often helium or nitrogen) sweeps the sample into A thermally-controlled column. (Jain, 1971) The analysis of blood and other body fluids for alcohol is most commonly performed using headspace gas chromatography due to its simplicity and the number of samples that normally run daily. The quality of GC results depends on many factors, including the stability of the gas chromatograph, the ruggedness of the injection system, and the sensitivity of the detector. Within this process, sample preparation and introduction provide the foundation for repeatability and reliability that are essential for the generation of quality data. Robustness and easy maintenance are also paramount to ensure continuous operation. (Gemme, 2012) In the case of gas-liquid chromatography, the

Interest and Exchange Rates Influence on Multinational Corporations Essay

Interest and Exchange Rates Influence on Multinational Corporations - Essay Example Interest rates play an important part in investment and saving decisions. Interest rates are the main instrument of central banks to conduct their monetary policies. Interest rates have impact on foreign exchange rates. Higher relative interest rates (↑) attract higher financial investments in the short-run due to expectations for higher returns. The simplest way to explain this is to compare bank interest rates between two countries. If, in UK interest rates for deposits are 5%, compared to US deposit interest rates of 3%, then it will be economically sound for businesses to transfer their bank accounts to UK banks for higher returns. This, in turn will increase demand for UK currency, also increasing supply of US dollars. Increased demand will increase the value of the UK pound as compared to the US dollar, thus positively influencing the foreign exchange rate of the pound (↑). On the other hand, expectations for future changes also influence exchange rates. Higher interest rates (↑) have negative long-run effect on investment decisions of international businesses. Although higher interest rates attract more bank deposits, they are associated with unfavourable business situation and higher business risks for returns on investments; therefore they result in higher cost of capital (Barron’s, 1994, cited by Murphy, 1996). Since businesses worldwide are highly dependent on loan conditions, it is economically justified for businesses to invest in regions where business climate is securer, i.e. interest rates are lower.
