Physical science - Essay Example prejudice and stereotypes; â€Å"lawn maintenance schedules are inconvenient.† This is a misconception because it is based on faulty information; lawn maintenance schedules can be efficient depending on the level of grass at which one wants the lawn to thrive. One may want a thick, manicured, and lush grass garden; alternatively, one may want a simple lawn of short grass. The internet and other credible sources present a wide variety of scheduling resources and systems for lawn owners depending on the level of maintenance one wants to achieve. The second argument is based on inductive reasoning; â€Å"turf becomes better the more it is irrigated.† This is theoretical and a misconception due to lack of biological and chemical knowledge; in Arkansas, more fine turf is destroyed as a result of overwatering than from under-watering. Lawns should be watered early in the morning and once a week in the summer months. Research shows that most cultivators of bermudagrass spend less on water than those who use zoysiagrass. The third argument is based on red herring; â€Å"lawn maintenance is expensive as compared to xeriscaping gardens, which take up less water†. This is a red herring argument since it diverts the topic of lawn maintenance to the water issue. While it is true that water is a problem in the United States, lawns can be effectively watered to reduce wastage. Watering in the heat of the day is ineffective. Watering late in the afternoon is less costly and an effective way of maintaining the

Measuring Depression for Individuals with Chronic Illness

Measuring Depression for Individuals with Chronic Illness The main intend of present study was to develop a reliable self-report indigenous measure of depression in people with chronic illnesses. Early detection of depression may decrease the risk of increment of disease burden and may provide insight for future coping skills to manage diseases in patients with chronic illnesses. Currently used scales for screening depression in Pakistan originated in Western countries. These scales are used as in original version, translated and/or in adaptive version (Naeem, 1990). Regardless of the high reliability and validity of the scales, there have been certain limitations in their capacity to identify depressive symptoms in Pakistani population. That is because of many cultural and regional differences that have an effect on mental disorders. These limitations of presently used Western scales possibly will increase the risk of mislaid symptoms in local population. By keeping these reviews in mind, it becomes visible that there is need to develop a new measure to assess depression in people with chronic illnesses with multivariate psychometric properties. That enables the clinician or researcher to measure the depression and its complicated effects on various chronic illnesses or vice-versa. Therefore this study attempted to develop a culturally receptive scale to measure depression as well as the assessment of validity and reliability of this scale named Depression in Chronic Illnesses Scale (DCIS). The Depression in Chronic Illnesses Scale is a 31-item, four points rating scale. Results ascertain Depression in Chronic Illnesses Scale as a reliable and valid apparatus with significant psychometric properties such as high internal consistency, test re-test reliability, sufficient convergent validity with other similar constructs and adequate discriminant validity with non-clinical population. The DCIS require respondents to report feelings that they experienced in last six months. Item number 10, 18, 26 and 31 are an Urdu adaptation of Beck Depression Inventory- (1961). The DCIS subjected to principal axis factor analysis. Factor analysis is most important method of test development because it provides the dimensionality of the factors and reveals underlying factors of the data (Field 2005; Widaman Floyed, 1995; Guilford, 1948). Consistency of the factor analysis reliant on the attribute of data that have to be checked its aptness before analyzing, and sample size is one of them. Sizes of the sample may vary according to the requirement (Field, 2005). Sample size of more than 200 cases is sufficient for the factor analysis (Guilford, 1956). Whereas another decisive factor for factor analysis is communalities after extraction will be greater than .5 (Field 2005). The present study fulfills these requirements (Table 2). Table 2 indicates that most of the items show communalities greater than .5. To test the sample adequacy and Sphericity, KMO and Bartlett’s test was also carried out. The acceptable range of KMO value must be greater than .5 (F ield, 2005). In present study the KMO value is .8 (Table 1) which falls within the moderate range (Field, 2005) and fulfill the requirement to produce reliable and distinct factors while analyzing. Finally Bartlett’s test of Sphericity is also highly significant (p Factor analysis was carried out to estimate the strength of the relationship of individual items with the concepts and to determine the possible essential structures of Depression in Chronic Illnesses Scale. Factor analysis quickly enables to take decision regarding item retention on the basis of good indicator of the construct and item deletion on the basis of poor indicator of the construct. After the assessment of decision making for factor analysis, specific criteria has been used that guide factor analytic decision making. That is based on the magnitude of the factor structure loading of one item on a factor opposed to another. When an item loaded on more than one factor the difference between the loadings must be at least .10 and an item needed .30 factors loading to be retained for further analysis (Nunnally, 1978). For the present study table 3 and 4 shows six distinct factors with Eigen Value greater than 1, whereas one strong factor with an eigen value of 11.01 that is expl aining 35.5% of the variance in the items. All items showed high loading on factor one ranging from .42 to .79. On the other hand rotation of factors extracted six factors by using Varimax Rotation Method. Though most of the items including items 1 (hopelessness), 2 (sadness), 3 (worthlessness), 4 (feeling of being rejected), 8 (pessimism), 12 (self-criticalness), 22 (hopelessness) are loaded on factor one which fall within the category of negative thinking. While items 5 (loss of energy), 6 (fatigue), 7 (fatigue), 17 (loss of pleasure) and 21 (loss of sleep) are loaded on factor two which is the category of lack of motivation. On the other hand third factor regret feelings comprised of item 9 (past failure), 18 (loss of pleasure) 28 (feeling of punishment) and 29 (loneliness). While item 10 (worry), 11(self dislike), 14 (hesitant), 15 (lack of confidence), 16 (uncertainty) and 19 (inability to make decision) are loaded on factor four fall within the category of indecisiveness. Whil e item 13 (feebleness), 20 (obsessed thoughts), 25 (crying), 26 (despondent) and 30 (self criticalness) are loaded on Factor five and this category is labeled as helplessness. While item 23(agitation), 24 (anger), 25 (crying), 27 (loss of appetite) and 31 (criticalness) are loaded on factor six and fall within the category of irritability. In present study item 25 (crying) loaded on factor five (helplessness) and factor six (irritability) simultaneously because the content of this item related to both factors. Almost all the item-total correlations of Depression in Chronic Illnesses Scale (Table 6) are highly positive within the suggested range of .30–.70 (Ferketich, 1991). Item number 1, 2, 3, 4, 8, 9, 10, 12, 13, 15, 17, 18, 20, 22, 23, 24, 25, 28, 29, 30 and 31 showed strong positive correlation with the total scores. Their correlations with the total scores ranging between .5 to .7 and considered to be better-quality items for assessing depression in chronically ill patients. Item number 5, 6, 7, 11, 14, 16, 19, 21, 26 and 27 showed moderate positive correlation with the total score. Their correlations with the total scores ranged in between .49- .39. The reasonably high levels of item-total correlation suggest that the items are sufficiently related. Inter-item correlations of Depression in Chronic Illnesses Scale are also calculated. Result indicates that item 1 (hopelessness) is highly correlated with worthlessness to feeling of being rejected to pessimism to past failures to self criticalness to feebleness to lack of confidence to uncertainty to loss of pleasure to obsessed thoughts to loss of sleep to anger to crying to feeling of punishment to loneliness and to criticalness. Furthermore item 2 (sadness) is significantly correlated with worthlessness to feeling of being rejected to pessimism to past failure to self criticalness to uncertainty to loss of pleasure to obsessed thought hopelessness to agitation to crying to despondent and to feeling of punishment. Item number three worthlessness significantly related to feeling of being rejected to pessimism to past failure to worry to uncertainty to loss of pleasure to inability to make decision to obsessed thoughts hopelessness to agitation to anger to crying to feeling of puni shment to loneliness to guilt. Item 4 feeling of being rejected is highly correlated with pessimism to past failure to worry to self criticalness to feebleness to lack of confidence to uncertainty to loss of pleasure to feeling of punishment to loneliness. Item 5 loss of energy is related to fatigue to feebleness to loss of pleasure to loss of sleep to feeling of punishment. Item 6 fatigue is highly related to feebleness to loss of pleasure to loss of sleep to feeling of punishment. Item 7 fatigue is highly related to self dislike to feebleness to loss of pleasure to loss of sleep to hopelessness to feeling of punishment. Item 8 is related to past failure significantly related to past failures to worry to self dislike to self criticalness to feebleness to lack of confidence to uncertainty to loss of pleasure to inability to make decisions to obsessed thoughts to hopelessness to agitation to crying to feeling of punishment to loneliness. Item 9 past failures is highly related to worr y to self dislike to self criticalness to feebleness to lack of confidence to uncertainty to loss of pleasure to inability to make decisions to obsessed thoughts to loss of sleep to hopelessness to agitation to crying to despondent to loss of appetite to loneliness to feeling of punishment. On the other hand self dislike, self criticalness, hesitant, lack of confidence, uncertainty, loss of pleasure, inability to make decisions, hopelessness, crying, feeling of punishment and loneliness are significantly relates with item 10 worry. Item 11 self dislike relates with hesitant to lack of confidence to loss of pleasure to obsessed thoughts to loss of sleep to hopelessness to agitation to loss of appetite to feeling of punishment. Item 12 self criticalness is highly related to feebleness to hesitant to lack of confidence to uncertainty to loss of pleasure to loss of sleep to hopelessness to agitation crying to loss of appetite to feeling of punishment. Item 13 feebleness is highly relate d with hesitant to lack of pleasure to uncertainty to loss of pleasure to inability to make decision to obsessed thoughts to hopelessness to agitation to anger to crying to despondent to loneliness to feeling of punishment. Item 14 hesitant is significantly related to lack of confidence to uncertainty to loss of pleasure to inability to make decision to hopelessness to agitation to anger to crying to despondent to loneliness. Item 15 lack of confidence is related to uncertainty to loss of pleasure to inability to make decision to hopelessness to agitation anger to crying to loneliness. Item 16 uncertainty is significantly related to loss of pleasure to inability to make decision to crying. Item 17 loss of pleasure is significantly related to inability to make decision to obsessed thoughts to loss of sleep to hopelessness to agitation to anger to crying to despondent to loss of appetite to feeling of punishment to loneliness. Loss of pleasure (item 18) is moderately related to inabil ity to make decision to loss of sleep to hopelessness to agitation to anger to crying to loss of appetite to feeling of punishment to loneliness. Item 19 inability to make decisions are related crying and despondent. Item 20 is highly related to hopelessness to agitation to anger to crying to loneliness to criticalness. Loss of sleep (item 21) is significantly related hopelessness to agitation to anger to loss of appetite to feeling of punishment to self-criticalness. Hopelessness (22) is significantly related to agitation to anger to crying to feeling of punishment despondent to loneliness. Anger is significantly related to crying to feeling of punishment to loneliness. Crying and despondent are more closely linked with self punishment and self-criticalness. Moreover feeling of punishment made its significant link with loneliness and self-criticalness. Link can be explained in the way that feeling of punishment arises when people have critical attitude for self and others and this attitude inculcate more criticalness towards self and the person entrap in vicious circle. Depression in Chronic Illnesses Scale displayed its strength by providing significant test re-test reliability (table 8). Test re-test reliability was estimated by administration of Depression in Chronic Illnesses Scale twice with the interval of one week between two administrations. Result establishes a high temporal stability of the scale i.e. a significantly high Pearson Product Moment Correlation of .716. It represents that the people with chronic illnesses maintain their relative position over a given period of time. Another reason of high test re-test reliability is those items that have significant item-total correlation in the Depression in Chronic Illnesses Scale. Because those items momentously contribute in enhancing reliability of the scale. In addition people with depression usually consistent with their opinion about the feelings, experiences and illness. For estimation of internal consistency of the Depression in Chronic Illnesses Scale, Cronbach’s alpha coefficient and split half reliability were computed. Cronbach’s alpha and split half reliability of Depression in Chronic Illnesses Scale was found to be .902 and .875 respectively indicate that Depression in Chronic Illnesses Scale highly internally consistent. Moreover high alpha range indicate that every single item of the scale assess the same construct as the total does. Therefore Depression in Chronic Illnesses Scale provides an excellent support for measuring depression in chronic illnesses. Convergent validity is demonstrated by high positive correlations between different measures of the same traits (Campbell Fisk, 1959; Domino Domino, 2006). The Depression in Chronic Illnesses Scale indicated good convergent validity in that it revealed significant and strong correlations with previously validated scales such as the CES-D i.e. .823 and HRDS i.e. .718 (table 9). To assess convergent validity, scores of the DCIS were compared to the scores of CES-D and HRSD scales. A positive correlation was expected between these three scales because of the superior clinical relevance of the CES-D and HRSD. A positive correlation between the DCIS, CES-D and HRSD provides an empirical support of the convergent validity of the newly established scale. Discriminant validity of a scale corresponds to the extent to which a test does not correlate considerably with that variable from which it ought to diverge (Campbell Fisk, 1959; Domino Domino, 2006). In order to explore discriminant validity, means, standard deviations and correlations between the scores of clinical population and non-clinical population were assessed (table 10, 11). The results demonstrated that there is a considerable difference in the means and standard deviations for both groups. The results further demonstrated significantly poor correlations between them, suggested that the DCIS can discriminate well between patients with chronic illness and normal peoples. Conclusion Depression in Chronic Illnesses Scale is constructing to provide a psychometrically reliable and valid self-report indigenous screening test for depression in people with chronic illnesses. There was no validated measure for screening the depression in chronically ill patients’ available indigenously. To fill that gap, the Depression in Chronic Illness Scale developed and is the first indigenous test which is culturally sensitive for screening depression in chronic illnesses. Findings of the study suggested that the DCIS captures several important areas of depression in patients with chronic illnesses. The scale will help clinician and primary care practioners to diagnose unnoticed depression missed due to the chronic disease burden. The scale has demonstrated good psychometric properties. Internal consistency for the overall scale was .902 falling within the recommended range, suggesting the scale is internally highly reliable. The factor analysis also supported the concept of depression as a multidimensional construct and consistent with the literature review. Significant input from chronically ill patients and health care professionals that guided in scale development. The scale is of four point likert type response system with high test retest reliability and sufficient convergent validity with Centre of Epidemiologic Study-Depression and Hamilton Rating Scale for depression. DCIS is a 31 items and 4 point likert type scale where each item scores on 0-3 rating system such as strongly agree 3, agree 2, disagree 1 and strongly disagree rated as 0. The collective sum of score is 93. The administration of the scale do not required much time i.e. five to ten minutes. Classificatory indices of the scores are, 0-30 indicates minimal depression, 31-41 indicates mild depression, 42-55 indicates moderate depression and more than 55 points indicates severe level of depression. The language of the DCIS is understandable and concise and does not require specific educational level. The only requirement is understanding and comprehension of Urdu language. Instructions of the scale are clearly stated without any ambiguity. The administration and scoring of DCIS does not need a skilled and trained interviewer. DCIS has hand scoring with little time consuming. In general, the DCIS is a useful test to provide a quick and proficient approach to assess depression in people with chronic illnesses. Furthermore, DCIS can also be use in research settings and will be as useful as in clinical settings. There are certain limitations that have a tendency to cloud the issue. The sample is to some extent small, containing only 220 chronically ill patients and the socioeconomic status of the participants is not accounted. However, as the DCIS was developed and validated only in Karachi, further studies need to evaluate its applicability in more demographically and culturally diverse samples of Pakistan. Gender differences may exist in terms of depression but present study did not address the issue. Future studies have to explore this possible gender difference. Another limitation of DCIS could be its applicability that is solely dependent on respondent’s mutual aid and their comprehension regarding Urdu language. Future studies can develop and validate the DCIS clinician rating scale to address this issue. There is need to control false positive and false negative responses from patients and the present study does not cater this issue. Further studies have to explore and control this issue.

Analysis of A Cry in the Dark A Cry in the Dark, based on a true story, is about a mother whose baby is killed during a camping trip along with her husband. The mother, Lindy Chamberlain claims to have seen her baby being carried away by a dingo and then assumes that the dingo is the cause of her baby's death. As she reports this to the police, she is inconsistent with some of the details that she reports along with other factors that stood against her, the police, meda, and even people watching this take place as it caused commotion in the news, accuse her of murdering the child. The mother and the father of the murdered baby are religious and dedicated to the religion of the Seventh Day Adventists.

Judicial Precedent Essay

Judicial Precedent is another important source of law, it is an independent source of law, where there are no legislations on the particular point in statute Books, and Judicial Precedent works great. Judicial precedent has been accepted as one of the important sources of law in most of the legal systems. It is also a continuous, growing source of law. According to Salmond, the doctrine of precedent has two meanings, namely (1) in a loose sense precedent includes merely reported case-law which may be cited and follows by the court, (2) in its strict sense, precedent means that case-law which not only has a great binding authority. But must also be followed. There are variety of different views about the nature of judicial precedent. According to Jermy Bentham, Precedent is a judge-made Law while Austine calls it as judiciary’s law; Keeton holds precedents as those judicial pronouncements of the court which carry with them certain authority having a binding force. In simple wor ds precedent means judge-made decisions which are used in further cases. A judicial precedent is purely constitutive in nature and never abrogative. Means it can create law but cannot abolish it. The judges are not at liberty to substitute their own views where there is a settled principle of law. They can only fill in the gaps in the legal system and so we can say that precedent means a case decided previously. Or precedent is any set pattern upon which future conduct may be based. Judicial precedent is a decision by a competent court of justice upon a disputed point of view which becomes, not merely a guide but an authority to be followed by all courts of co-ordinate or inferior jurisdiction and administrating the same system until it has been overruled by a court of superior jurisdiction or by a statute of superior authority, e.g., an Act of Parliament. The justification of the binding rule of judicial precedent is based on the several reasons these are that, precedent is based on practical experience. Rather than logic, it is based on convenience in the sense that it is provided in settled law and thus saved the labour of judges. It prevents error of judgment by individual judges, it prevents partiality on the part of the judges It helps lawyers to take a cautious view of the development of law on the basis of past judicial experience because of above all factors precedents are become achieve important place as one of the important source of law. Precedents can be classified into two categories: (1) Authoritative and (2) Persuasive. The authoritative precedent is one  which has a binding force and the judge must follow it whether he approves it or not. Authoritative precedents are the decisions of superior court of justice which are binding on subordinate courts. For ex. Supreme Court, High Courts, Persuasive precedents, on the other hand, is on which the judges are under no obligation to follow but which they may take into consideration at the time of making decision. Now from all above discussion we are well able to understand precedent, how we discussed the position of precedent in real practice and its recent value in administration of justice. In the recent years, the value of the doctrine of precedent has become a debatable issue. In England the importance of precedent is much more than in any continental country, that is why it is often said that judicial precedent is an unique feature of common law countries because the great body of the common law or unwritten law is almost entirely the product of decided cases and common law of England has been created by the decision of English judges and precedent is not merely evidence of the law but a source of it and the courts are bound to follow the law that is so established. House of Lords is the highest Court in England, its decisions bind all the inferior courts, the House of Lords itself is bound by its own previous decision but this position after a long controversy and various debates become change after the famous classic case. Boys v. Chaplin, 1968 IAIIER 283 and it is finally decided that as the House of Lords is the highest court in England, its decisions are absolutely binding on all inferior courts. But House of Lords is now not bound by its own earlier decisions and so nowadays House of Lords is not bound by its own previous decisions. In continental countries like Germany France, Italy, judicial precedent has only instructive value and it is not authoritative. In these countries its importance is no greater than that of a textbook of law. In India judicial precedent has great value. The position of precedent becomes clear after 1950 and the doctrine of precedent gets a constitutional recognition. Art. 141 of the constitution provide that law declared by the Supreme Court to be binding on all courts, within the territory of India. It is clear from the wordings of Article 141 that the law declared by the Supreme Court is binding on all courts in India. But there after in various debates question arises that, whether the expression all courts include Supreme Court also. This question gives birth to various new views, that whether Supreme Court follows the British model of the House  of Lords of ‘be bound’ or the U.S.A. Supreme Court ‘not be bound’. This question was first discussed by S.C. in the famous case. Now it is finally concluded from all forgoing discussion that the position of precedent from past to presen t is changed in vast dimensions and importance. Value of precedent is now decreased to some extent and new concepts of prospective overruling has evolved to avoid the complications in vast changing society. In true sense precedents enable the judges to re-shape law according to the social need and at the same time the binding authority of the precedent acts as an effective check on the arbitrary discretion of the judges. Precedent helps common people to know about the intricate principles of law. Precedent helps Lawyers in their argument without waste of unnecessary time and energy whenever they want to cite any case-law. It also provides useful guidelines for the judges in deciding cases before them. But there are some contrary arguments towards precedent as Bentham did not recognize precedent as law at all because it lacks binding force of the state. Some critics argue that, statute law is more important than precedent, they say that, judicial precedents are published in law reports which are in such a large number that it becom es practically difficult to find out a particular case from such a voluminous legal literature and so it is very time consuming, they also contend that, at one time, different courts express conflicting opinions on the same point which renders the validity of precedent doubtful and uncertain and there is always a possibility of erroneous judgment in such a case. Another objection which is quite often raised against precedent is that development of law through case-law more or less depends upon chance, because there is no test available for determining the validity of law made by precedent. Sometimes erroneous decisions of S.C. create practical problems for the subordinate judges as they are bound to follow these decisions howsoever wrong or defective. This adversely affects the growth and development of law in the right direction. But despite the aforesaid critical argument, judicial precedent has been as one of the important sources of law in most of the legal systems particularly U.K., U.S.A., Australia, Afro-Asian countries and India as the merits of the binding effect of the precedent (decision) it must be stated that it gives certainty and uniformity to law and brings about its scientific development and precedents always remain an effective weapon of shaping and developing  law according to the needs of the changing society.

Compare and Contrast Essay Essay

Trayvon Martin and Jordan Davis were just two young teenage boys whose lives were taken from this world. The two cases for these two boys have some similarities between each other they were two 17 year-old African-American boys, both boys were unarmed, and the stand your ground law was used for each case. There are also some differences between the cases such as George Zimmerman was found not guilty while Michael Dunn was found guilty, Zimmerman stayed on the scene of the crime while Dunn did not do the same, and last eye witnesses were present to Dunn’s case but Zimmerman had zero eye witness. This is the twenty-first century yet we still have hate towards other races. In February 26, 2012 â€Å"Trayvon Martin a seventeen year old African American boy went to the store for some candy and a soft drink. George Zimmerman a Hispanic man was the neighborhood watch captain for the Retreat at Twin Lakes† (HLNtv.com). Now in November 23, 2012 Michael Dunn a White man â€Å"leaving a wedding reception for his son pulled into a gas station for wine and chips next to the SUV Jordan Davis† another seventeen year old African American boy â€Å"and three of his friends were in† (CNN.com). Zimmerman was monitoring the neighborhood when he calls 911 to report â€Å"a suspicious person.† He was â€Å"instructed to not get out or approach the person† who was. Martin. Zimmerman â€Å"disregarded the instructions given to him by the police and moments later shot Martin† and unarmed boy (CNN.com). If he was unarmed walking back to his house how could he have had any intention of being aggressive towards another man? In Dunn case he got into an argument with Davis and his friends about the loud music asking them to turn it down. Dunn said he â€Å"saw Davis reach down in his passenger seat to pull out a 12 or 20 gauge shotgun.† So â€Å"Dunn grabbed his gun an open fired ten bullet, three of which struck Davis.† Later when the car was searched no gun was found in the car (usatoday.com). Davis just like Martin was an unarmed boy. In the presence of both cases Zimmerman and Dunn both found there selves in a self-defense situation in other terms the â€Å"stand your ground law† (huffingtonpost.com). The Zimmerman case was considered self-defense but he would not have had to defend himself if he didn’t approach Martin. Also when Martin was unarmed what did Zimmerman need to defend himself of? Dunn on the other hand was not in a calm state of mind he was the â€Å"prosecutor portrayed him as a gunman whose â€Å"blood started to boil† because an armed teenager had disrespected him† (usatoday.com). Even though Dunn thought Davis had a gun he should not have fired off ten rounds rapidly. Dunn could not have been defending him and his wife when the teenagers were unarmed. They were no harm to Dunn and his wife. Zimmerman was the neighborhood watch men and was patrolling the street when he saw Martin. There were not one eye witnesses to seeing what happened at the scene besides Zimmerman a nd Martin who was dead. The only thing they had to go off of was the bruises forming and blood running from the back of his head, also the recording of the gun shot from the police recording of Zimmerman’s phone call. In Dunn’s case he was at a gas station with people around including the four men he was talking to about the loud â€Å"rap crap† music as he called it (CNN.com). Usually when you flee the scene of a crime it means you are guilty. After Zimmerman got out and came up too Martin and defended himself by shooting him. He stayed at the scene was it because no one was around and he already called the cops, and he knew that with his head bloody it was constituted as the â€Å"stand your ground law?† As for Dunn he fled forty miles back to his motel as soon as he shot off ten rounds. There he took â€Å" his dog for a walk, ordered pizza, and drank rum and cola† (CNN.com) Zimmerman was found not guilty after a year and six months went by. The six women jury found George Zimmerman not guilty. The jury had three choices to convict Zimmerman of â€Å"guilty of second degree murder, to find him guilty of the lesser charge manslaughter, or to find him not guilty. The jurors deliberated for more than sixteen hours total, including the thirteen on Saturday alone† (CNN.com). Now for Dunn even though he had pretty similar crimes as Zimmerman he was found guilty. Dunn received â€Å"a minimum of twenty years on one count, another twenty year count, and another minimum of twenty  year count† (usatoday). Works Cited Neale, Rick. â€Å"Fla. USA TODAY.
