Vincent Romano Dr. Myers English 1301.4033 March 27, 2017 Concussions in Football Playing football is a childhood dream for many kids as they are growing up. Football is a great way to compete, make new friends, and even pay for a free college education by receiving a full ride scholarship. Sometimes, for very few, football can be a career. As a child, most of the time, safety is the last thing on the mind. In the Public Service Announcement (PSA)"Concussion Awareness - HOSA Public Service Announcement" by the Centers for Disease Control and Prevention, there were successful presentations of both ethos and logos, but there could have been a better use of pathos to strengthen the emotional response. A logos appeal is clearly presented in the second scenario when the coach makes it apparent that logically, if a player shows signs of a concussion, the coach needs to follow the concussion protocol to prevent further damage. Ethos is successfully used in the PSA announcement by showing a credible coach to relay the message in this scenario. Pathos, an emotionally ch arged appeal, was not demonstrated as much as the other approaches and could have been enhanced by more quickly engaging the audience. The first major reason the PSA on concussion awareness was logically apparent is by the use of a logos appeal. A male narrator details the effects in a way that when a player shows signs of a concussion, the coach needs to follow the concussion protocol to prevent further damage. The narrator makes it understood that following the concussion protocol is extremely important because if a concussion has occurred and the correct protocol is not followed, it could have a big impact on the athlete's career and quality of life. Though the PSA provided logical information about concussions in football, a possible way to strengthen it would be to refer to progress researchers are making in brain concussion examinations. Another successful appeal in the PSA on concussion awareness was the use of ethos. The ethos is the credibility the reader can assume from the information provided. In the first scenario, at the :10 mark, after the coach sends the player back into the game when the player clearly shows signs of a concussion, across the screen in big, red, bold letters that states, "REALLY COACH?" ("Concussion Awareness"). The ethical idea that can be taken away from the message is that the coach needs to be a responsible leader and make the right and credible decision. The ethical information provided during the thirty-two-second-long PSA was effective because it suggests in the second scenario, at the :19 mark, an alternate solution. The coach identifies the concussion symptom the player is displaying and then makes him sit out of the game and be looked at by the team trainer ("Concussion Awareness"). In contrast, the PSA on concussion awareness emotional or pathos appeal seemed to be lacking compared to ethos and logos. It is not until the halfway point, :16 mark, that the male narrator begins to express his message ("Concussion Awareness"). The narrator begins to talk and direct his message towards coaches. The narrator's voice is in a calm, low tone, as if he is having a normal conversation on a topic that is not a serious matter. The pathos appeal in the narrator's message could have been enhanced and more heartfelt if the narrator were displaying more passion and sympathy in his voice to grab more of an emotional response from the audience. The greatest impact the PSA on concussion awareness made relating to the pathos appeal comes in the opening scenario, at the :2 mark ("Concussion Awareness"). The PSA posits in big, bold, red capital letters, "CONCUSSION?" ("Concussion Awareness") across the top of screen. The video continues to show one player making a big hit on anoth er player. The player that gets hit falls back, and at the same time, that player's helmet comes off and soars through the air. This opening scene in the PSA best represents pathos, because as the big hit is demonstrated, the audience can see and sense the impact that just transpired as well as presume the possible consequences the fallen player will suffer from the hard blow. The pathos

Facts About Soft Coral (Octocorals)

Facts About Soft Coral (Octocorals) Soft corals refer to the organisms in the class Octocorallia, which includes gorgonians, sea fans, sea pens, sea feathers, and blue corals. These corals have a flexible, sometimes leathery, appearance. Although many resemble plants, they are actually animals. Soft corals are colonial organisms, which means they are formed of colonies of polyps. The polyps of soft corals have eight feathery tentacles, which is why they are also known as octocorals. One way to tell the difference between soft corals and hard (stony) corals is that the polyps of hard corals have six tentacles, which are not feathery. Here are some stony coral characteristics, with some of the key differences with soft corals identified: They have polyps that secrete a cup (calyx or calice) in which they live. The polyps of soft corals usually have feathery tentacles.They may harbor zooxanthellae, algae that live within coral polyps and can produce brilliant colors. Others may be colored by bright pink, blue or purple pigmentation.They may contain spikes called sclerites, which are made of calcium carbonate and protein, and are located within a jelly-like tissue called coenenchyme. This tissue lies between the polyps and contains canals called solenia, which transport fluids between the polyps. In addition to providing structure to the coral and protection from predators, the shape and orientation of the sclerites can be used to identify coral species.They have an inner core made out of a protein called gorgonin.They may have a variety of shapes, including fan-like, whip-like or feather-like, or even leathery or encrusting. Classification Kingdom: AnimaliaPhylum: CnidariaClass: AnthozoaSubclass: OctocoralliaOrders:Alcyonacea (the horny corals, also known as the gorgonians, sea fans and sea feathers)Helioporacea (blue corals)Pennatulacea (sea pens) Habitat and Distribution Soft corals are found worldwide, primarily in tropical or subtropical waters. Soft corals do not produce reefs but may live on them. They may also be found in the deep sea. Feeding and Diet Soft corals may feed during the night or day. They use their nematocysts (stinging cells) to sting passing plankton or other small organisms, which they pass to their mouth. Reproduction Soft corals can reproduce both sexually and asexually. Asexual reproduction occurs by budding when a new polyp grows out of an existing polyp. Sexual reproduction occurs either when sperm and eggs are released in a mass spawning event, or by brooding, when only sperm are released, and these are captured by female polyps with eggs. Once the egg is fertilized, a larva is produced and eventually settles to the bottom. Conservation and Human Uses Soft corals may be harvested for use in aquariums. Wild soft corals may also attract tourism in the form of dive and snorkeling operations. Compounds within the tissues of soft corals may be used for medicines. Threats include human disturbance (through humans stepping on corals or dropping anchors on them), overharvesting, pollution, and habitat destruction.

Macromolecules and Enzymes Essay Example | Topics and Well Written Essays - 2000 words

Macromolecules and Enzymes - Essay Example Effect of different physical parameters including temperature, enzyme concentration and pH was determined for the enzyme tyrosinase. Phenylthiourea, an inhibitor was also used to study its effect on the eznyme. Every living thing on earth is made of carbon, and each compound containing carbon is known as organic compound. Four kinds of major organic compounds are known carbohydrates, lipids, proteins and nucleic acids. Proteins are organic compounds made up of amino acids joined by peptide bonds between the amino and the carboxyl group of the adjacent amino acids. The proteins can be classified according to their structure; the linear chain of amino acid is called the primary amino acid. In secondary structure there occurs a regular repeating structure that is stabilized by hydrogen bonds. In tertiary structure the stabilization occurs by salt bridges, disulfide bonds, hydrogen bonds. Protein subunits combine together to form the quaternary structure. Enzymes are also an organic compound, basically a protein. â€Å"All enzymes are proteins, but all proteins are enzymes†. Enzymes are biocatalyst that speed up the rate of the reaction but do not take part in the reaction. Enzymes have active site, basically a group of amino acids that binds with the substrate, which further carry out the reaction to give a specific product. Enzymes are known for their specificity for substrates, although not all enzymes are specific. The rate of the reaction governed by enzymes is increased when the optimal conditions like temperature, pH, and substrates concentration are provided for the reaction. Two theories are known for the action of enzymes on substrates. 1. The lock and Key Mechanism and, 2) Induced fit theory. Enzymes are also inhibited by inhibitors, which can be substrate analog or any other compound that binds to the enzyme such a manner that the enzymes is unable to function. Inhibitors can be of two kinds, competitive, uncompetitive and non-competitive.

Market research Assignment Paper Example | Topics and Well Written Essays - 750 words

Market Assignment - Research Paper Example Energy drinks are products that became popular in the year 2000 and their popularity kept on increasing since then. These products are really suited for those individuals who have to work at night hours or have a hectic nature of work on their shoulder. The launch of a 12 hour energy drink would be considered a market leader product in a market where the current offering is only a 5 or a 6 hour version of the energy drink. As it is considered to be newer version of the product in the existing market, it would be really beneficial if a market research is conducted to analyze whether the product will succeed in the market or not. As the company in question lacks the budget to conduct a survey or the focus group research analysis, the only option left would be to use public information on the energy drink market that would help in identifying the target markets for such an energy drink. On the basis of the information and the current buying behaviors of individuals, it seems obvious tha t the target market for a 12 hour energy drink would be the age group of 16 to 30 years old. The recent trend of advertising for the energy drinks currently focus on the young generation of such age group. This age group is can further be divided into athletes, gamers, party lovers and workaholics. Now it would be really difficult to target all these different target groups with a uniform/similar product but since the product brings an extension to the time period i.e. 12 hour version, it may be possible that it can serve all the different target groups with a uniform product i.e. similar product, packaging, etc. By identifying the target market, a segment of the market would be identified. This market segmentation would help in reduced marketing costs for the company. For a successful market segmentation and target market, proper consumer data would be analyzed with respect to the energy drinks. Using the public information, both quantitative and qualitative would be analyzed. Quan titative data would include such as age group, the age group of 16 to 30 years old would be the perfect market as far as the age group is concerned for the 12 hour Power O energy drink. The income factor would not be much of a concern as far as the target market is concerned, the prices of such energy drinks are cheap and these can be easily bought by the target age groups. As far as the qualitative data is concerned, there would be no effect based upon the education of that particular target market. The occupation of the target market may come into question with regards to the occupation. People working at night hours are deemed to be fond of energy drinks, hence a 12 hour Power O energy drinks would really help them. The only question that would really matter would be the fact that such 12 hour energy drink would have ingredients that might have negative effects on the users. Such 12 hour energy drink would have heavy amount of caffeine that can be considered to have negative and harmful effects on the users of such energy drinks. Hence at the target age range of 16-30, it could be excessively harmful and it can create legal restrictions on the sale of such energy drinks (as is the case in Norway and Iceland where under 16 sales is prohibited) because of the increased amount of caffeine

Plea Bargaining Assignment Example | Topics and Well Written Essays - 250 words

Plea Bargaining - Assignment Example On the part of the prosecution, the advantage is the assurance of having a conviction, albeit for a lesser crime or minimal penalty, over the possibility of the accused walking off with an acquittal. On the part of the defense, the benefit is the chance of being convicted to a lesser offense or for the same offense for a significantly lighter penalty over the possibility of a conviction on the original charge and for the maximum penalty [Premo v.  Moore (Docket No. 09-658)]. Finally, especially for high profile parties to case, a plea bargain avoids prolonged trial which means less publicity and media frenzy. It is admitted that a criminal prosecution is an action of the State and the prosecutor represents the State; nevertheless, the victim needs to be consulted in the process of plea bargaining. The victim suffered from the criminal act and will have difficulty in overcoming the trauma and in moving on if he still feels that he has never been truly vindicated with the plea bargai n deal. I agree with plea bargaining. Although it is never a perfect system, it sure does make the wheels of our criminal justice system move forward for the common good. Reference List: Jeff Premo v. Randy Joseph Moore, Docket No. 09-658. Accessed on May 26, 2011. Available at http://www.supremecourt.gov/opinions/10pdf/09-658.pdf

Eyewitness Testimony Essay

Eyewitness Testimony Essay The use of eyewitness testimony is infamously a primary source of evidence used within the judicial system around the world; however its use has raised various questions as to its reliability and validity especially within court cases. This essay explored first of all, the biological factors of memory and recollection of memories within the human brain. Memories are believed to be stored and processed within the hippocampus part of the brain where it goes through the multi-store model (Atkinson and Shiffrin, 1968). This is where danger of the reliability of memory occurs. It was argued that eyewitness testimony is a reliable form of evidence especially with its validity in terms of the events leading up to the use of EWT; what is deemed important information is believed to be remembered more clearly. Sigmund Freud (1920) suggested that memories can only be retrieved by encouraging remembering past episodes and re-instating these past memories into their consciousness. Psychologists N ibett and Ross (1980) quoted that the reason why eyewitness testimony is persuasive is that it influences the jury on a deeper level. However, eyewitness testimony posed more disadvantages than advantages with the various factors that affect it such as weapons focus in incidents involving weapons which cause distractions and loss of memories. The primary psychologist that tested the use of memory was Elizabeth Loftus who conducted various experiment to test this, such as the Automobile Destruction experiment in the 1970s. After having collated all the arguments together, it was suggested that improvements must be made in order to improve the quality of eyewitness testimony; these included the legal system and police forces involvement in collating information as quickly as possible. The most imperative form of evidence when investigating a crime is the honesty of witnesses on trial, the application of eyewitness testimony. Though the use of eyewitness testimony by juries is considered most valuable, the question of fallibility of witness statements poses various problems and issues. Eyewitness testimony has been a thriving aspect of the Criminal Justice System, an incredible amount of research into this element of cognitive psychology questions the reliability of peoples memory especially using it as evidence to determine the outcome of the trial and convictions. Research into the reliability of evidence, often referred to as witness psychology is renowned as being the longest established area of law and psychology, dating back to the beginning of the 20th century.  [1]   The area of eyewitness testimony has always posed a problem with reliability and the effectiveness of human memory. Human memory is described by cognitive psychologists Atkinson and Shiffrin (1968)  [2]  as a three stage theory in which memory is modelled in, this memory stage model is called the Multi-Store Model. The Multi-store model theory consists of the memory being divided into three stages, the first stage being the sensory store, the second stage is the short term memory (working memory) and the third being long term memory. The transfer of information from one store to another is controlled by the process of attention and rehearsal of memories. One of the most critical assumptions made by cognitive psychologists is that the human mind has a limited capacity for processing information. Therefore, any external information that the environment consists of is often very difficult for the human mind to assimilate and process; so people are selective about what information is to be retrieved and this is otherwise known as attention, where some information is assimilated while other pieces are ignored. The first stage of the multi-store model, the sensory store, is where the information from the senses (iconic, echoic, tactile, olfactory and gustatory), is transferred into but this is only for a very short period of time. The initial information retrieved by the senses is then transferred into the short term memory store; this is transferred through attention given to the information transferred from the senses involved. When the information has been transferred into the short-term memory store, this is the store concerned with forgetting information and this information is ultimately lost entirely. Therefore, for information to be remained in the memory, from the short term store into the long term store, the information must be rehearsed. Rehearsal is the cycling of information through the memory, this rehearsal of memory can be carried out in two different methods. Therefore this essay will investigate whether the application of eyewitness testimony statements is a reliable form of evidence to be used by the judicial system. Furthermore, this essay will argue whether eyewitness testimony is ideal to use as one of the most important pieces of evidence to use or whether the application of eyewitness testimony is fallible. After comparing for and against the reliability of eyewitness accounts, an evaluation will be drawn over how eyewitness testimony can be improved to an extent where it can be further accurate. This essay will explore the elements of eyewitness testimony and how these factors can determine whether an eyewitness account is accurate. These elements include the effect of weapon focus on witness memory, how leading questions can manipulate witness statements and recollection of memory, reconstructive errors of memory and the application of psychological experiments when exploring the function of these elements on the human memory. Th e application of the eyewitness testimony includes multiple formal questioning sessions with witnesses on trial, taking statements of the events witnessed and witnesses appearing in court with the jury. The issue of integrity when applying eyewitness testimony accounts is delegated to the jury, who are assigned the role of determining the judgement of whether the eyewitness statements are fallible or reliable  [3]  . The use of eyewitness testimony has a profound and compelling effect on the outcome of a trial and conviction, and this is why an accurate eyewitness testimony is needed in order to gain justice. The Aspects of Eyewitness Testimony As a consequence of the limitations of information processing in the human mind, witness statements need to be reviewed for accuracy and if any external factors of either the environment or the function of memory may have affected the outcome of the witness account  [4]  . Quite often, when the memory cannot recall the entire incident or situation, it may result in the unknown areas being replaced by events that may never have took place in reality but the mind may perceive as a potential occurrence and therefore causes fallibility in the eyewitness testimony. In essence, the memory may fill in gaps where it fails to recall what may have happened  [5]  . Many factors affect eyewitness memories which are illustrated below: Interference of Memory Processing: The period of time that has lapsed between the witnessing of the incident and the questioning of the eyewitness can determine the amount of information that the witness can recall. On the other hand, interference which is the loss of old stimuli as a result of new information can also subsequently reduce the accuracy of eyewitness accounts.  [6]   Leading Questions in Witness Interviews: A leading question in its form or content, suggests to the witness being interviewed what answer is desired or leads them to the desired answer. Some questions can often be made more suggestive than others and these questions the legal concept of a leading question. The main pioneer for investigating the consequences of particular leading questions was Elizabeth F. Loftus in 1974.  [7]   Schemas: The human mind has evolved its memory capacity and the ability to remember certain aspects by organising information into categories, otherwise known as schemas  [8]  . Schemas help organise memories that can consist of familiar people, objects and situations and allow people to understand and act appropriately to whatever is encountered. Arousal, Anxiety and Violence Distraction: Quite often, cognitive psychologists have questioned the poor recall of eyewitness accounts is primarily a result of where their attention is focused upon. A possible reason for arousal, anxiety and violence distraction could be that a violent incident, with the use of weapons, draws the focus of the witnesss attention away from who is causing this anxiety, which results in little or no processing of other information.  [9]   Weapon Focus: When a witness views a crime in which a weapon is used as a method of violence and distraction, the weapon achieves its purpose in distracting the attention of those witnessing the crime. The distraction affects the witnesss attention due to the potential threat of violence9. External Influences: Quite often, external influences can affect the accuracy of eyewitness accounts, especially if the media has been influencing the events that have taken place. The witness may re-interpret their witness statements to match what the media has claimed may have existed or happened. Apart from the media, other external influences may include other witness accounts of what happened and/or the type of environment that the situation may have occurred in, e.g. in darkness, low-lit room etc. Conformity: Through the questioning process that witnesses must endure, group questioning in particular, gives into reason the reliability of witness recollections as they may conform in order to fit each others interpretation of what happened. Reliability of Eyewitness Testimony The use of eyewitness testimony has provided crucial evidence that can often lead to the identification and arrest of a criminal suspect or a hazardous event can be avoided. Eyewitness testimony impacts strongly upon the trial process and the verdicts that are given by the jury are quite often influenced heavily by eyewitness accounts. Stern and Dunning, 1994  [10]  quoted that eyewitness testimony is perhaps the most compelling types of evidence presented to police investigations and criminal trials. Although the human memory and its information processing ability, has substantial amounts of limitations that can lead to invalidity and inaccuracy, it does however, demonstrate a unique ability to process information where the acquired stimulus information is stored. The human mind can potentially hold millions of pieces of information, though not all at once, which when acquired by the brain can be reinstated and remembered. The memories that the mind deems as important for growth and use consistently is life are episonic which represents the episode of the memory where as certain skill or piece of information; semantic which identifies what that piece of information consists of and what it is and finally procedural which processes who that information is to be used or handled. For example, teaching a child how to read a book at a particular age is episonic, knowing what a book is, is semantic and how to read the words in a book would be procedural.  [11]   The process of information being transferred from the short term memory into the long term memory was an experiment conducted by psychologists Welch and Burnett in 1924. The experiment was to test the theory of the serial position curve where it consisted of the subjects being presented with a list of 16 words in which they had to recall in order. The results of this experiment, illustrated the serial position curve in which the recollection of words and the results of the experiment were graphed and this illustrated a curve effect were the last recalled words were remembered best whereas the words in the middle of the recall were remembered poorly. Cognitive psychologist, Sigmund Freud believed that memories were allocated in the brain  [12]  . Freud referred to these memories as true memories and described that they lay deep in the unconscious element of the brain, where they lay undisturbed as a factor of surface mental activity. Freud insisted that these memories were never lost or forgotten as they are only inaccessible and latent, having become a part of the unconscious  [13]  . For these memories to be accessed, Freud promoted the technique free association. By encouraging witnesses to reminisce about past episodes that have occurred within their lives, Freud insinuated that they could reinstate long-forgotten yet important memories from their past into their consciousness. However, it can be argued that the true memories that Freud insisted exist in the human sub-conscious are in fact potential complex blendings of both fact and fiction. Memory is an extremely fragile aspect of the human mind that can potentially be supplemented, altered and reconstructed by external stimuli that can question an event that may never have occurred. However, it is argued that the human mind is capable of remembering significant pieces of information that is considered vital and important. This is considered one of the key factors in which juries do consider eyewitness testimony accounts as a vital piece of evidence. Psychologists Nibett and Ross, 1980 quoted that the reason why eyewitness testimony is persuasive is that vivid testimonies have a strong impact on observers so this conclusively means that they are easier to remember especially upon the jury  [14]  . Though the potential invalidity of eyewitness accounts is extensive, error made in witness accounts are extraneous when the observers are able to distinguish between accurate and inaccurate witnesses  [15]  . However, there may be a possibility that the eyewitness account is accurate but leading questions by the criminal investigation team may provoke the memory to be changed to fit the question or the most relevant and fitting answer  [16]  . The Unreliability of Eyewitness Testimony The malleability of eyewitness accounts demonstrates the excessive inaccuracy of it being used as a vital evidential piece in the courts and criminal justice system. Many hypotheses have been established that suggest reasons for the valued use of eyewitness testimony. Saunders et al believe that jurors tend to place too much faith in eyewitness testimonies; however the problem lies with whether eyewitness testimony is a reliable source of evidence to use  [17]  . The inaccuracy of witness accounts is demonstrated by the various aspects that intercept with each other and substantiate hesitation for its use as evidence. The use of leading questions can quite often alter information/intelligence or can quite often misinterpreted accounts to match the information that the witness has been presented with. An experiment conducted by Elizabeth Loftus and John Parmer illustrates the interaction between language and memory in 1974  [18]  . The reconstruction of an automobile destruction consisted of two experiments in which subjects were shown films of automobile accidents. After the observation, the subjects were then asked questions about the events that occurred in the films; How fast were the cars going when they smashed into each other? The use of the word smash demonstrated higher estimations in the speed of the car as opposed to other verbs used in place of smash such as collided, bumped, contacted and hit. When the experiment was repeated a week later, the subjects who received the word smashed were more likely to agree to the question asked Did you see any broken glass? even though there was n o recollection of broken glass within the video. These results highlight the theory that the questions asked in relation to an event can result in a reconstruction of a witnesss memory of that event. Though witness memory is quite often inaccurate in that they fail to distinguish the events that had occurred, quite often, the human memory can remember erroneous events and details that may be introduced by third party interference. In the 1970s, Elizabeth Loftus conducted an experiment to demonstrate how third party interference can invalidate witness accounts by introducing false facts. Subjects were shown a slideshow of a car at an intersection with either a yield sign or a stop sign. The experimenter then asked the participants questions which falsely used the word stop sign instead of yield sign which is what was actually shown in the slideshow. The results indicated that subjects remembered seeing the false image; the introduction of false cues altered the memory of the participants in the experiment. Bartlett conducted an experiment in which he read a story The war of the ghosts out loud to a group of participants where he concluded that participants attempted to fit the story into their western schemas and as a result, distorted it during recall  [19]  . This showed that they were not recalling the information exactly as it had been presented to them, but were making assumptions at the story, based on their own understanding. This correlates with what a witness may assume a criminal or crime scene may look like and therefore use this to describe the suspected. Schemas are an effective method of processing and encoding information  [20]  . The idea of schemas were originally established by Frederick Bartlett in the 1930s which involved a large number studies in which he showed ways in which participants made sense of whatever they were shown affects the way they recall it later  [21]  . For example, in one of his studies, Bartlett showed participants unfamiliar line d rawings and instructed them to memorise it. Bartlett then asked his participants to talk aloud at the same time as memorising the picture. He found that different participants made sense of the figures in different ways. Later in the experiment, the participants were asked to draw the figures as they remembered them and Bartlett discovered that the schemas which they established during their initial encoding influenced their recall. Therefore, schemas may influence what witnesses may define what a criminal looks like or behaves like and this may influence their account of events. Through the questioning process that witnesses must endure, witnesses can either be questioned on a one-to-one basis where the interviewer questions the witness independently or witnesses can be questioned as a group if the incident has been witnesses by multiple people. In particular, group questioning which gives into reason the reliability of witness recollections as they may conform in order to fit each others interpretation of what happened. This conformity can purposely invalidate information as the witness does not want to be isolated from the events that the other witnesss describe as having happened. This subjective information again affects the testimony because false information is being interpreted is invalid due to conformity of information. The weapons focus effect  [22]  perceives to be a result of the witnesss attention being predominantly directed towards the weapon, resulting in diversion of attention away from the situational aspects and the criminal suspect. When a witness views a crime in which a weapon is used as a method of violence and distraction, the weapon achieves its purpose in distracting the attention of those witnessing the crime. The distraction affects the witnesss attention due to the potential threat of violence. Although an incident has occurred, the attention of the witness is primarily upon the weapon so they are not observing the rest of the incident or the person who is posing the threat and this causes the witness to have lack of information about the incident. This area of eyewitness psychology is known as weapon focus; unfortunately this distraction results in a very poor eyewitness testimony as the witness is unable to recall events and descriptions. Unfortunately, most crimes involve the use of a weapon as a vulnerability tool, which in essence causes the stress and anxiety levels of the witness to rise and therefore will fail to encode and remember vital information. Eyewitness inaccuracy may also be a result of errors that occur within the memory process; the memory is divided into three distinct stages of processing: encoding, storage and retrieval. The occurrence of errors is very likely at any particular stage within the memory processing stages. Acquiring information or otherwise known as encoding is illustrated within the Yerkes-Dodson principle which according to its theorists, an increase in arousal improves performance up to a certain point. Once arousal has passed the critical point which is otherwise known as the optimum, performance tends to decline and these results in poorer memory performance. So, in essence when a person is moderately aroused, the information is encoded best as opposed to extreme arousal or stress where the information is lost or encoded insufficiently. The Yerkes-Dodson theory  [23]  demonstrates that if a witness observes a crime that is substantially violent and/or makes the witness experience high levels o f fear and anxiety, they are less likely to remember any significant levels of information because of the extreme stress which results in encoding of information inaccurate. This conclusively makes their eyewitness account unreliable because they fail to remember any substantial amounts of information and detail of what happened and of the perpetrator. The question of witness account accuracy raises questions about whether the time after the incident occurred, if the account is still valid as evidence because quite often, large amounts of time and substantial interference can deteriorate the information from memory. This deterioration refers to the loss of stimulus information as a result of passed time. The amount of time that has lapsed between the occurrence of the event and the questioning and testimony of the witness can quite often determines the amount of information the witness can recall  [24]  . This interference is due to the loss of old stimulus information caused by new stimulus information; this can also reduce the accuracy of eyewitness accounts. People are more likely to overestimate the duration of brief events but on the other hand underestimate the duration of prolonged events (Penrod, Loftus and Winkler, 1982). Other psychological research has demonstrated that the presence of a weapon also reduces the accur acy of eyewitness accounts. Evaluation of Eyewitness Testimony Taking into consideration the flaws in which eyewitness accounts may consist of, which effectively invalidates the testimony, these flaws can be avoided by both the eyewitness and the criminal justice system that use the accounts as a form of evidence. Most importantly, the way in which witness accounts are handled is vital in establishing a valid eyewitness testimony with as much truth as possible. The interviewing process which is conducted by the criminal justice system i.e. police, courtroom judges, need to be done in a careful and delicate way so that there is no decay or deterioration of information. Though the memory of the witnesses may differ, depending on age and memory capacity, quite often the initial first few hours after the occurrence of an incident is vital in collecting as much valid information as possible. So, the interviewing of witnesses should be conducted right after the incident when possible to avoid any decay of information and/or third party interference. In terms of the actual interviewing process, the use of leading questions should entirely be avoided unless the witness has mentioned specific events or descriptions which would not invalidate information as it has been confirmed by the witness. Leading questions  [25]  can quite often add new information that the witness may not have known about and will therefore mention false information in order to fit their account with what is evidently known by the police. Specific questions that can be used in the interviewing process may help the witness to run through their track of events which in some circumstances reveal any recollection of events without any external influence. Quite often through the criminal investigation, the witness needs to be interviewed many times to establish the course of events and important descriptions, whether this is through the crown prosecution trial or by the police. If later eyewitnesses need to be interviewed, they should be able to recall as much information that they reported initially, avoiding any extra information that they may have picked up from third party interference. So in essence, there is no uncertain information but information that the mind has remembered and rehearsed within their memory and indicates a positive recollection of events. Though no control can be given to what eyewitnesses will focus on and concentrate entirely on, measures on how information is collected can partially help to distinguish between valid and false information within accounts. Conclusion It can be concluded that the use of eyewitness testimony will also be used as a vital source of evidence by the criminal justice system for years to come. Eyewitness testimony can hold vital pieces of information that cannot be retrieved from any other source, without eyewitness testimony, the police would find it incredibly difficult to discover any potential clues and evidence of what happened or description of what the perpetrator physically looks like. Criminal cases in which there is not eyewitnesses to give evidence are usually those cases which find it incredibly hard to convict the guilty so have to rely upon other physical evidence such as CCTV, DNA, fingerprints etc. However, the use of eyewitness accounts seems to create a lot of doubt in whether it is a reliable source of evidence to be used because its accuracy is questioned based on interpretation. The use of leading questions and third party interference can decay any initial recollection of events that the eyewitness may have believed to have happened. But the human memory has flaws within itself regardless of extra information that can falsify or invalidate the recollection of what occurred and why. The initial pioneer of evaluating eyewitness evidence, Elizabeth F. Loftus  [26]  highlights the flaws of eyewitness accounts and of the human memory. The conclusions in which Loftus has discovered were advantageously used to improve quality of interviews and valid eyewitness accounts but unfortunately cannot eliminate all invalid information. So, in essence, the question as to whether eyewitness testimony is a reliable source of evidence still remains unclear on the basis that it is vital evidence which is needed to collate important information. However, its reliability is questioned in terms of validity and how much the witness is able to accurately recall all pieces of information especially having experienced high amounts of anxiety and stress. Eyewitness testimony will always remain a vital source of evidence but its use should be delicately considered to avoid any false information or invalid convictions.

Imagery, Metaphors, and Diction in Dulce et Decorum Est All exceptional poetry displays a good use of figurative language, imagery, and diction. Wilfred Owen's "Dulce et Decorum Est" is a powerful antiwar poem which takes place on a battlefield during World War I. Through dramatic use of imagery, metaphors, and diction, he clearly states his theme that war is terrible and horrific. The use of compelling figurative language helps to reveal the reality of war. In the first line, "Bent double, like old beggars under sacks,"(1) shows us that the troops are so tired that they can be compared to old beggars. Another great use of simile, "His hanging face, like a devil's sick of sin,"(20) suggests that his face is probably covered with blood which is the colour symbolizing the devil. A very powerful metaphor is the comparison of painful experiences of the troops to "[v]ile, incurable sores on innocent tongues."(24) This metaphor emphasizes that the troops will never forget these horrific experiences. As you can see, Owen has used figurative language so effectively that the reader gets drawn into the poem. The images drawn in this poem are so graphic that it could make readers feel sick. For example, in these lines: "If you could hear, at every jolt, the blood/ Come gargling from the froth-corrupted lungs/ Obscene as cancer, bitter as the cud,"(21-23) shows us that so many men were brutally killed during this war. Also, when the gas bomb was dropped, "[s]omeone still yelling out and stumbling/ [a]nd flound'ring like a man in fire or lime.../ [h]e plunges at me, guttering, choking, drowning."(11-12,16) These compelling lines indicate that men drowned helplessly in the toxic gasses. These graphic images are very disturbing but play a very effective role in the development of the poem. Another tool in developing the effectiveness of the poem is the excellent use of diction. The word "blood-shod" explains how the troops have been on their feet for days without rest. Also, words like "guttering", "choking", and "drowning" shows us that the troops are suffering in extreme pain and misery. If you haven't noticed, most of these words are examples of cacophony, which are words with harsh and discordant sounds. As this poem is about how harsh and terrible war is, Owen's use of cacophony is very effective in generating the tone of the poem. Is it really that sweet to die for one's country?
