Allergic Asthma Case Study Example | Topics and Well Written Essays - 1500 words

Allergic Asthma - Case Study Example In 2001, 73 people per 1000 were diagnosed to have chronic allergic asthma with the help of the medical professional; this is current prevalence of allergic asthma. What is more interesting to note, is that the prevalence of allergic asthma among minorities is disproportionably higher than among the native population. This may be explained by the social conditions, which often define the general state of health and immune system among patients from ethnic minorities. Asthma was also one of the leading diagnoses in the hospitalizations, and its morbidity was equal to 1.6 per 100,000 of the native population. Thus, accounting the noted information the importance and relevance of the present discussion is not under any doubt. (Adams, Smith & Ruffin, 2001) first of all, the process of diagnosis and its confirmation is clinical, and there are no blood tests, histopathological or radiographic investigations which can be performed to confirm the suggested asthma. Mrs. H addressed the doctor for medical assistance in 2004. ... sence of wheeze during these periods were the signs of the asthma, but for the reasons of her addressing the medical establishment with this problem for the first time, there had been no previous notes in relation to her state. She was 29, and she had used to have such health problems for about 10 years before, but with the exacerbations passing quickly and with long breaks she didn't see the reason for serious medication. Mrs H's family history stated that her both parents had chronic allergic rhinitis. Mrs H herself noted that tobacco smoke worsened her state, as well as dust inhaling; she had never smoked herself. Her social status was favorable, and her profession was accounting, thus she used to work with papers which could often be the sources of dust. She didn't have any signs of breath difficulties after use of aspirin or other medicines. Wheeze was episodic but was becoming more frequent. It is useful to remember, that the symptoms of allergic asthma may sometimes be mixed with the other symptoms, which may make the diagnosis doubtful or wrong; if the patient has difficulties in breathing without wheeze, fixed wheeze, or mentions the weight loss, the chest X-ray is recommended for the determining of the exact diagnosis, which in such case may be either COPD, or tumor, bronchiectasis, etc. As for the family history in diagnosing allergic asthma, it is one of the most important risk factors to account when diagnosing any allergic diseases; 'asthma is linked to both parental and sibling history. The strongest association is with maternal atopy'. (British Thoracic Society, 1997) Diagnosis of asthma with the account of theoretical knowledge Bearing in mind that Mrs H didn't have any additional symptoms which could make the diagnosis doubtful, she was asked to

Finance Problems - Speech or Presentation Example In order for the company to have the credit standing â€Å"comfortably within the A range,† the target range to be chosen should be at the lower end of the ranges, or the upper limit of the lower rating as its lower limit, and the upper limit of the A rating for the upper limit. Thus, for the fixed charge, the company must choose 3.40x – 4.30x; the lower limit is the upper limit for the Baa rating. For the funds from operations/total debt, the range should be 55-65; 55 being the upper limit for Baa. For the long-term debt/capitalization, the range should be 22-30; the 30% being the lower limit for the Baa rating, rating below the A rating. One of the factors to be included in the decision include the companys research and development spending, which as mentioned in the question can be assumed as capitalized and part of the intangible asset of the company. Because this is an intangible, other investors may not buy into it as a security in terms of providing higher amounts of loans to the company, compared to its competitors. While it has higher than average spending for R&D, this is not a tangible cost that could back up any claims for insolvency, which is also a concern to the investors. Also, the companys ability to use other tax credits is another consideration for settling with the target ranges, because these has effect on the three key figures for the company to qualify for a certain credit rating. Because R&D is capitalized, the additional tax credits by increasing the leverage may not be so significant to the company when R&D is capitalized into intangibles. Because it invests in higher than average R&D, and has higher foreign credits, if these are not affected by increasing the financial leverage of the company, it does not give huge benefit to the company in the process.

Cardiac Activity and Ventricular Tachycardia (VT) Waveform

Cardiac Activity and Ventricular Tachycardia (VT) Waveform Lachlan Donnet-Jones Sudden cardiac death (SCD) is one of the leading causes of mortality in Australia. One of the primary causes of SCD is cardiac dysrhythmias, such as, Ventricular Tachycardia (VT). The most effective treatment for life-threatening cardiac dysrhythmias is defibrillation. This essay will examine the relationship between cardiac activity and the Ventricular Tachycardia (VT) waveform, and discuss how defibrillation may terminate this dysrhythmia, allowing the heart to return to a normal rhythm. The typical healthy adult heart will have a resting heart rate of between 60 and 100 beats per minute (Saladin, 2011). When the heart beats abnormally fast, it pumps less effectively, which decreases the level of perfusion to the tissue of the body, including the heart itself. This rapid heart rate increases the hearts muscle tissues (myocardium) demand for oxygen, and without intervention, can lead to the death of myocardial cells, which is known as a Myocardial Infarction (MI) (Huazers, 20). Each year in Australia approximately 55,000 people suffer a heart attack, or an Acute Myocardial Infarction (AMI). This is equal to 150 heart attacks per day or one in every 10 minutes (Heart Foundation). The Australian Bureau of Statistics reported that over 350,000 Australians will suffer an AMI at some point in their lives (ABS, health survey). In Trappes’ 2012 research article, Trappe notes that there is no single factor that causes an AMI, it is a multifactorial problem, however, approximately ninety percent of AMI’s are caused by tachyarrhythmia’s (Trappe, 2012). Before one can gain a thorough understanding of dysthymias, it is necessary to develop a fundamental grasp of the heart’s electrical conduction system and the associated physiology and pathophysiology. The primary function of the electrical conduction system is to transmit electrical impulses from the sinoatrial node (SA node) (normal site of conception) down to the atria and ventricles, triggering a contraction of heart muscle (myocardium) and controlling the heart rate. In a normal sinus rhythm, originating from the SA node, there are three phases; atrial depolarisation, ventricular depolarisation and atrial and ventricular repolarisation. The SA node is found within the wall of the right atrium proximal to the entrance of the superior vena cava. Similar to all electrical nodes within the heart, the SA node is composed of pacemaker cells which generate automatic and regular electrical impulses. These electrical impulses travel through the walls of the right atrium, causing contraction of the heart muscle (myocardium), to the atrioventricular node (AV node) via internodal conduction tracts (anterior, middle, and posterior). A final SA node conduction pathway, known as Bachmann’s bundle (interatrial conduction tract), transmits electrical impulses across the heart to the left atrium. On an electrocardiogram (ECG) this atrial depolarisation is represented by the P wave. The fibrous annulus is a non-conductive layer of tissue which prevents the electrical impulse from travelling outside the perimeter of the atrium. The primary function of the AV node is to process the electrical impulses from the atria to the bundle of His in a way that slows the impulses arrival at the ventricles by approximately 0.12 seconds. This delay allows for the atria to empty and the ventricles to fill before the next contraction. After the bundle of His, the electrical impulse will travel down the right bundle branch and the left common bundle branch. These bundle branches continue to subdivide into smaller branches, the smallest of which connect to the Purkinje network, an elaborate mesh of minute Purkinje fibres which spread throughout the ventricles. In a normal functioning heart it will take an electrical impulse approximately 0.2 seconds to travel from the SA node to the Purkinje network in the ventricles. On an ECG, this is shown as the P-R interval. At this point the impulse causes the ventricles to contract, pumping the blood out of the ventricles and into the systemic circulation. This depolarisation of the ventricles is represented by the QRS complex. Immediately following a QRS complex, is a period of time in which there is no electrical activity in the myocardium. This is known as the S-T segment and is normally represented as a flat line, level with the isoelectric line of an ECG. The proceeding T wave represents the repolarisation of the ventricles to their resting state. If at any point in this process the electrical impulse is disturbed, it can create a cardiac dysrhythmia, such as if the SA node were to produce rapid electrical impulses, resulting in tachycardia (fast heart beat). Ventricular Tachycardia (VT) is a type of tachycardia that originates within the inferior chambers of the heart, called the ventricles. The ventricles are the primary pumps of the heart, therefore, when they are compromised it can quickly deteriorate into a life-threatening dysrhythmia, such as, ventricular fibrillation (VF) or asystole (Chou, 2008). The diagnosis of VT is made by examining the rhythm seen on a 12-lead electrocardiogram (ECG). Although numerous diagnostic criteria have been developed, such as the ‘Brugada Criteria’ (Brugada, 1991), the following are the most commonly accepted (Riley, 2008). The rate of VT is above 100 per minute, typically 150 to 200, with a regular rhythm. The R-S complex is absent in precordial leads, and there are three or more consecutive Premature Ventricular Contractions (PVCs) present (AV dissociation). The ectopic pacemaker is below the Atrioventricular node (AV node), therefore, the PR interval is irrelevant. In addition, different ambulance services will have their own specific diagnostic criteria for VT, for example, Ambulance Tasmania (AT) Clinical Practice Guidelines (CPG’s) state that the rhythm must present with QRS complexes of over 0.12 seconds, and be sustained for a period of over 30 seconds (sustained VT). VT can be classified using three methods; morphology, episode duration, and symptoms. In regards to morphology, there are two primary categories of VT; monomorphic and polymorphic. Monomorphic VT has numerous causes, but is determined by consistent appearance across all leads of an ECG. A common reason that the beats from each lead appear the same, is because the impulse is being generated from an increased rate of automaticity in a single point from the left or right ventricles. This means that the pacemaker cells, such as the Purkinje fibres in the left and right ventricles, that are able to reach an action potential on their own accord (automaticity), have increased the rate at which they fire impulses (intrinsic rate). Another reason for monomorphic VT is due to the presence of a re-entry circuit within the ventricle. A re-entry circuit occurs when an electrical impulse constantly travels in a constricted circle within the heart, as opposed to moving from one end of the heart to the other, like a normal electrical impulse circuit. Although monomorphic VT has many causes and contributing factors, the most common cause is scarring of the myocardial tissue from a previous MI episode. The scarred tissue left behind does not conduct electrical impulses, and therefore, the potential for a circuit around the scar can result in tachycardia. This is similar to the aforementioned re-entrant circuit, and is a common cause of other dysrhythmias, such as, atrial flutter (Af) and supraventricular tachycardia (SVT). Scar-related monomorphic VT is predominantly prevalent in patients who have a previously survived a MI, particularly in those who have damaged myocardium as a result (John, reference). Unlike the cons istent rhythm seen is monomorphic VT, polymorphic VT is an irregular rhythm that has constant variations in its morphology. A second method to define VT is studying the duration of the episode. Three or more consistent contractions on an ECG, originating from within a ventricle at over 100 beats per minute, is determined as VT. If the tachycardia rhythm terminates itself in under 30 seconds, it is considered non-sustained VT. If the rhythm continues beyond 30 seconds, it is considered sustained VT. The final method to classify VT is reviewing symptoms. When a patient is in VT, the loss of co-ordinated atrial contraction and high heart rate can impair cardiac output (CO), and therefore, they will not have a palpable pulse. This is known as Pulseless VT. Pulseless VT is concomitant with an absence of cardiac output (CO), and therefore, according to AT clinical practice guidelines, is to be treated as worst case scenario, which is ventricular fibrillation (VF), a shockable rhythm (CPG Reference). In a report from the American College of Cardiology, Zipes et. al note that VT can occasionally be accompanied by reasonable cardiac output and may even present as asymptomatic, however, the heart will not tolerate this rhythm for a sustained period of time, and will eventually deteriorate to pulseless VT or VF. Supraventricular Tachycardia (SVT) with a bundle branch block (BBB) or Wolff-Parkinson-White syndrome is commonly misdiagnosed as VT (Trappe). This is due to the similar diagnostic characteristics, such as, wide QRS complexes and high heart rates, which are mutual in all wide complex tachycardia (litfl). It is important to differentiate the two because certain medications used to treat SVT could potentially worsen the patient’s condition. As Trappe notes in his research article ‘Treating critical supraventricular and ventricular arrhythmias’, it is always beneficial to treat for the worst case scenario, in this case, VT (Trappe, 2010). This opinion is mutual in regards to Ambulance Tasmania CPG’s, where it recommends treating for worst case scenario. Once a shockable dysrhythmia has been recognised, it is necessary to intervene with an external source of electrical activity to correct the hearts rhythm. Defibrillation is the standard and most effective treatment for cardiac dysrhythmias, such as VT and VF (Reference). Defibrillation is the process of using a device called a defibrillator to deliver a therapeutic measure or ‘shock’ of electrical current through the heart. The current delivered, aims to depolarise a critical mass (Critical mass theory**) of the heart muscle (myocardium), interrupting the dysrhythmia and allowing the heart’s natural pacemaker, the SA node, to return to a normal sinus rhythm. Defibrillators are becoming widely available in the form of transvenous, implanted (implantable cardioverter-defibrillator), or external (automated external defibrillators) devices. Despite the different forms a defibrillation device may present in, they all operate on the same principle. There are two different methods of delivering an electrical shock from a defibrillation device; monophasic and biphasic waveforms. Monophasic is the ‘old’ method in which the electrical current travelled in one direction through a patient’s chest. The second method is using a biphasic waveform, meaning the current is delivered to the heart in two vectors (two directions). Due to the use of two vectors, the peak electrical current needed to revert a dysrhythmia is decreased to 200 joules, as opposed to 360 joules of a monophasic waveform. Due to the high voltage (360 joules) used in monophasic waveform it can cause superficial burns to the patients skin. Additionally, _____ found the use of a biphasic waveform to be more effective at returning the heart to a sinus rhythm and resulted in less damage to myocardium, leading to better patient outcomes (Reference) . ____ notes that for the aforementioned reasons, monophasic waveform defibrillation is quickly being replaced with biphasic (Reference).

Essay --

In the novel, Emma, Austen introduced her audience to a new idea of patriarchy. While she is known to satirize society for the â€Å"faulty education of female children, limited expectations for girls and women, and the perils of the marriage market† (â€Å"Austen, Jane†). Austen expresses the irony of the men of her patriarchal society and proposes the ideal gentleman in Mr. Knightley. In Emma, Austen moves away from â€Å"a traditional idea of 'natural' male supremacy towards a 'modern' notion of gender equity† (Marsh). Jane Austen is a revolutionary in the way she transforms the idea of Nineteenth Century patriarchy by not â€Å"reinforcing the traditional gender stereotypes† (Rosenbury) but instead challenging the status quo. While her characters still hold some ties to traditional ideals, Austen proves to be ahead of her time, influencing the way gender is regarded today. In the Eighteenth and Nineteenth centuries, the idea of patriarchy ruled the many societies all over the world. Particularly in Britain, its â€Å"overarching patriarchal model† (Marsh) had â€Å"reserved power and privilege for men† (Marsh). Also during this time period feminist literature began to arise and was invaded by, â€Å"the complex social, ethical, and economic roots of sexual politics†¦ as testimony to gender bias and the double standard† (â€Å"Sexual Politics and Feminist Literature†). In Jane Austen’s writing, readers have been aware of her constant themes of female independence and gender equality. However, many have criticized the author for the fact that many of her â€Å"individualistic† female characters have ended up married. However, â€Å"for pragmatic reasons, the author’s conclusions favor marriage as the ultimate solution, but her pairings predict happiness† (â€Å"Austen, Jane†). Als... ...ied about his intentions during the entire novel, no one truly knows him. Frank’s uncle, Mr. Churchill is inferior to his wife in regards of control. Throughout the novel the reader hears more about his wife than they hear about him. Their relationship represents complete switch of the traditional idea of man being superior to woman. The Knightleys however, John and Isabella, are purely conventional and are ideal couple for Nineteenth Century society’s times. Mr. Elton does not represent true gentility while Mr. Weston too gentle. Although all of these characters have their flaws, Austen finds her perfect figure in George Knightley. His infallible nature is unrealistic, yet it gives society the ultimate gentleman to aspire for. Austen’s Emma is more than a comedic novel of manners but also a quintessential piece that fits perfectly into the lives of today’s society.

Introductions to Interviews and Interrogations: False Confessions

In 1988, Ted White was clubbed in the head and face at his mattress business between 12:45 and 1:55 p. m. White died of his injuries three days later and was never able to tell the police officers of the incident. There were no witnesses found and the police never discovered any fingerprints or DNA to help identify the actual perpetrator. Regardless, police originally suspected Matt Mason of the murder but were unable to bring a case against him. Mason and Tinney were acquaintances. Glenn Tinney original pled guilty to the murder of ted white in 1992. There was evidence that was presented at court that got Tinney sentence exonerated. The evidence they had to get his sentence exonerated was the fact that none of the confessions matched the facts of the crime and an Ohio judge reversed Tinney’s conviction. The prosecutor investigator was told Glenn Tinney may know something about Mason’s participation in ted white’s murder, Tinney said that him and mason killed Ted white together but then a couple of days later he said he did the crimes alone. The police also uncovered that Glenn Tinney gave other statements that was not consistent with each other or with the facts of the crime. The court concluded that upon close comparison of Tinney’s confessions, he â€Å"confessed to killing a man he could not identify, for conflicting motives which don’t match the facts, at the wrong time of day, with a weapon that does not match the victim’s injuries, by striking him in the wrong part of the head, and stealing items the victim either still possessed after the attach or probably never possessed. † Because of these reasons, the court said it would be â€Å"manifestly unjust to deny withdraw of the guilty plea† because the confessions did not provide any support for the murder conviction (McGinn, 2013 ).References McGinn, A.

Amadou Diallo Essay

Social cognition is the study of how people form attribution or judgments about themselves and the social world from the social information they received from their environment (Chapter Review, 2010). However, it was discovered often marked by apparent errors and biases. People make quick judgment based on their past experiences, hence at times leading to tragic endings. The Amadou Diallo case study was an example of the tragic error which was made by four New York City Police officers. The police shooting of an unarmed man was an act of automatic inferences which happens when people use mental shortcuts to simplify the amount of information they receive from the environment. Automatic thinking is known as the thinking that is unconscious, unintentional, involuntary and effortless (Taylor, Peplau, & Sears, 2006). While, schemas are mental structure people use to arrange their information regarding the social world around themes or subjects: schemas affect what information we notice, think about, and remember (Chapter Review, 2010). During the incident February 4, 1999, Carroll had made a low-effort automatic thinking with schemas when Diallo reached into his jacket to get his wallet by assuming that Diallo was reaching for a gun in his pocket, and shouted â€Å"Gun! † to alert his colleagues. Officer Carroll’s action was due to his natural instinct or response as most criminal would reach into their pocket for gun during the detection of police officers. He had use schemas to form an expectation of the event in which made him to expect a gun pulling out of Diallo’s jacket rather than his wallet. As he attends to his schema-consistent knowledge: criminals would pull out guns from their jacket when they spotted police officers; his schemas filtered out any inconsistent information: Diallo reached in his jacket to get his wallet; had caused the NYPD officers to fire at Diallo. Besides that, there are also a few theories or concept under automatic thinking with schemas that had shown relevance to the Amadou Diallo case study, such as, accessibility. Accessibility is the ease with which schemas can be brought to one’s mind (Taylor, Peplau, & Sears, 2006). The four police officers had practiced accessibility when they saw Diallo ran up the outside steps toward his apartment house doorway at their approach, ignoring their orders to stop and â€Å"show his hands†. When they saw Diallo ran after they claimed to have identified themselves as NYPD officers, they might assume that Diallo was the serial rapist they were searching for, as logically a serial rapist or a criminal would ran when approached by police officers to avoid getting caught. The ease of the thought that criminals would run when they spotted police officers, had made the four police officers to identified Diallo as a criminal, although that was not the truth in Diallo’s case. As a result, a firestorm had unfortunately occurred. Furthermore, the four police officers had practice priming in this case study. Priming is the process which related to recent experience that made schemas or concept to come to one’s mind more readily (Taylor, Peplau, & Sears, 2006). For example, when Officer MeMellon fell down the steps, appearing to be spot, the other three officers might assume that Diallow had fire a gunshot towards Officer McMellon hence causing him to fell down those steps because they had linked it to their recent experiences of gunshot and thought that Officer McMellon had been spot and that Diallo had shot him with his gun. As one would logically fall back when shot. Perseverance effect was also shown in this case study. Perseverance effect is known as the tendency for people’s beliefs about themselves and their world to persist even when those beliefs are discredited (Taylor, Peplau, & Sears, 2006). When the four NYDP officers thought Diallo matched the description of a (since-captured) serial rapist, it might be due to the fact that Amadou Diallo was an immigrant to the United States and the four police officers could have the belief that immigrants are the major causal crime increment in the Unites States. Hence resulting the police officers to think the worse out of Diallo when he ran and even though he was reaching into his jacket to get his wallet, the police officers had persisted that the square object had been of a firearm although in logical terms both wallet and gun do not share the same shape and size. On the other hand,people also tend to use mental strategies and shortcuts to organize and make sense of their social world, especially when they are lack of full processing time, lack of solid information to use for decision making, information overload, or when the issues are not important to them (Taylor, Peplau, & Sears, 2006). Mental strategies and shortcuts help people to make decisions easier and allow them to get on with their lives and not turn every decision into a major hurdle. Four NYDP officers had practise judgmental heuristics when they made judgments about Diallo. Police officers thought Diallo had matched the description of a (since-captured) serial rapist. This might be because that Diallo was a dark skin immigrant which had logically matched the description of the serial rapist leading officers to made a quick decision so that they do not need analyse in detailed and make a major hold-up over the matter. Furthermore, the four police officers also did performed availability heuristic in this case. Availability heuristic is a mental rule of thumb whereby people base a judgment on the ease with which they can bring something to their mind (Taylor, Peplau, & Sears, 2006). During the incident, Diallo had been mistaken that he was reaching into his jacket to get his firearm whereas he was actually reaching to get his wallet. Officer Carroll had shouted â€Å"Gun! † to his colleagues. His judgment might be due to his ease with which he can bring to his mind, which in this case, was automatically thinking that Diallo’s wallet was a gun, hence warned his colleagues about the matter. Attitude heuristic is the determination of what is â€Å"true† based upon an individual’s feelings towards or for a matter (Taylor, Peplau, & Sears, 2006). The four police officers also had carried out attitude heuristic towards Amadou Diallo. For example, these police officers might dislike Diallo because he was an immigrant or ‘black’ person therefore assuming that Diallo’s intention, plan, or doings would also be bad too. This caused Diallo to be misinterpreted to be a criminal trying to escape from police detention rather than his true intention, which was believed to initially intend to show the NYPD officers his identification card in his wallet before he wrongly shot. Besides theories and concept of automatic thinking with schemas, the Amadou Diallo case had also displayed a few relevant theories of social perception. During the incident, the four police officers had displayed the attribution theory. Attribution theory is a description of the way which people explain the causes of their own and other people’s behavior (Taylor, Peplau, & Sears, 2006). It is because that Diallo had run up the outside steps of his apartment after they claimed to identified themselves as NYPD officers, and that he had reached into his jacket, the police officers have made a cause and effect explanation towards Diallo’s behavior hence assuming that he was a criminal or the serial rapist they were searching for, therefore Diallo had run up in the attempt to escape and when he reached into his jacket for his wallet, they thought that he was reaching for his gun to defend himself. Due to this theory, it made sense of he reason four police officers have assumed that Diallo was a criminal and they had to fire back Diallo. All this might be due to the attachment of meaning they decode from Diallo’s nonverbal behavior. In addition, the fundamental attribution error was also shown in the incident when the four police officers have focus on Diallo’s action to run and reached into his jacket, rather than the situation causes of his action, which was intending to reached into his jacket to get his wallet to show the police officers that he was innocent when he was approached by the police officers and asked to â€Å"show his hands†. Fundamental attribution error is known as the tendency to overestimate the extent to which a person’s behavior is due to internal, dispositional factors and to underestimate the role of situational factors, one reason people make fundamental attribution error is because the observer only put their attention on the actor, while ignoring the situational causes of the actor’s behavior (Taylor, Peplau, & Sears, 2006). Furthermore, Diallo had also displayed the spotlight effect in this case study. The spotlight effect is the tendency to overestimate the extent to which our actions and appearance are salient or clear to others (Taylor, Peplau, & Sears, 2006). When Diallo had reached into his jacket to get his wallet, he might had assumed that the NYPD officers know or understand what he was doing, which in his case, was the probability to take out his wallet and show them he was not the criminal or man they were searching for. However, the four police officers were not aware of his action hence assumed that he has a gun, hence fired at Diallo. Moreover, police officers had also displayed the aggression objects as cues concept during the shooting event. Aggression objects as cue is an aggressive stimulus that act as an object that is associated with aggressive response, and whose mere presence can increase the probability of aggression (Taylor, Peplau, & Sears, 2006). The aggressive stimulus in this Diallo case is the guns that the police officers possessed. When the police officers had encountered a threatening or violent stimulus, they were more likely to â€Å"shoot† regardless of what stimulus actually appeared (Baumann & Desteno, 2010). Due to the possession of firearms, the four police officers had the higher possibilities to response aggressively towards Diallo, hence the gun act as the object that associated with their aggressive response. Without the firearms that the four police officers possessed, the act of aggression towards Diallo would decrease therefore the firestorm would not have happened. According to Correll et al. (2002), it was found that participants’ performance shown difference regarding race of the targeted person. When a decision making process was time limited, participants had made more errors shooting unarmed African American targets than unarmed White targets. Whereas, participants had made more errors not shooting armed White targets than armed African American targets. In other words, participants were more likely made errors evaluating African American targets as threatening compared to White targets. This means that because Diallo was a ‘black’ immigrant, it increases his rate of being shot. This is an act of stereotype as because Diallo was a ‘black’ immigrant, they assumed that he might be a criminal, hence the police officers thereby increasing the likelihoods for certain interpretations and ensuing actions during the crucial moment, resulting them to mistaken Diallo’s wallet as a gun, hence shot him. In another words, it is like the Arabs possess guns, resulting in more frequent mistaken â€Å"shootings† of Arab men within the context of the shooter bias paradigm (Unkelbach, Forgas, & Denson, 2008). There are also group prejudices that had been displayed in the Amadou Diallo case study. The four police officers had shown prejudice against Diallo because he was a dark-skin immigrant, hence they have ordered him to stop and â€Å"show his hands† without confirming whether he was the serial rapist they were searching for. Seeing the suspect holding a small square object, Officer Carroll yelled â€Å"Gun! † to alert his colleagues, believing thatDiallo had aimed a gun at them at close range, the officers opened fire on Diallo. Diallo was a West African immigrant with no criminal record (Cooper, 1999). It was clearly shown the act of prejudice towards Diallo, whom was misunderstood or misinterpreted just because of his race. Furthermore, discrimination was shown in the Amadou Diallo case when the four NYPD officers had opened fire to shoot Diallo without proper investigation on his identity and the square object that he was holding during the incident. The action carried out by the four police officers was unjustified and harmful towards Diallo because he was a West American immigrant in the United States. Finally, illusory correlation was also shown in the Amadou Diallo case. An illusory correlation is the tendency to see relationships, or correlations, between events that are actually unrelated (Taylor, Peplau, & Sears, 2006). When Diallo ran up the outside steps of his apartment and pulled out his wallet, the police officers had correlated his action to a criminal’s doing hence leading them to assume that he was a criminal ready to open fire at them in short range. These two events are distinctive and hardly correlated. Because Diallo was a West African immigrant, therefore the police officers correlated the two events together, causing Diallo his innocent life.
