Statistical vs Clinical Significance Statistical

Words: 649 Length: 2 Pages Document Type: Essay Paper #: 34387647

In other words, p values correspond to statistical significance, while NNT corresponds to clinical significance. In clinical trials, statistical validity reflects the theoretical basis of the study, with hypotheses being formulated and quantified in terms of likelihood. Clinical significance is concerned with the practical outcome of trials, and with the results of actual treatment and how this relates to the hypotheses that are proven or void.

2.

In nursing practice, both statistical and clinical significance play an important role in research. In practice, however, it is clinical significance that should have the greatest impact upon nursing practice. Clinical significance provides actual data from research conducted to determine such effects. It concerns the outcome of trials, while statistical significance is more concerned with determining new research and the likelihood of success before trials have been conducted.

Indeed, Davidson notes that an advantage of NNT is the format of its results --…… [Read More]

Statistical Test for Significantly Different Sample Means

Words: 573 Length: 4 Pages Document Type: Essay Paper #: 84133105

Independent – Samples t-Test
The Independent sample t-test is among the group of inferential statistical test. This test seeks to compare the means of two unrelated samples in a survey. The t-test determines whether the mean of the two sample is significantly different statistically (Paul & Garg, 2014). According to Ruane (2005) for this test to be undertaken, both samples must have scores with one carrying nominal scale and another one a numerical scale. The sample carrying the nominal is a grouping variable and is the independent variable. The sample with the numerical scale is a test variable and is the dependent variable (Ruane, 2005).
This paper seeks to determine the statistical significance between the means of work shift (day and night shift) and the mean of the number of widgets produced in either shifts. This will be undertaken by use of the independent sample t-test. The work shift is…… [Read More]

Nhst

Compare and Contrast Null Hypothesis Significance Testing (NHST)

The most commonly used statistical technique for testing the impact of the factor being discussed on observations is Null Hypothesis Significance Testing (NHST). Consequently, NHST is the famous approach to inferential statistics, especially when conducting quantitative research. Despite being the dominant approach, NHST has also become increasingly controversial given the belief by a considerable number of people that it is a flawed statistical method. The controversy and consideration of Null Hypothesis Significance Testing as a flawed statistical approach has contributed to the development of alternatives whose proponents consider more beneficial or advantageous unlike NHST. However, an understanding of Null Hypothesis Significance Testing requires correct interpretation of p values.

Meaning of p = .05

P value is commonly used across statistical approaches including regression analysis and t-tests because it determines the statistical importance or significance in testing a hypothesis. According to Frost…… [Read More]

60.2% of white inmates were executed that had initially been removed from being under a sentence of death versus 38.9% of blacks that met these criteria as part of the sample. While this cross-tabulation shows there is not a statistically significant relationship between blacks vs. whites having their sentences commuted, Hispanic Origin will prove to have statistical significance when bivariate correlation analysis is used to analyze the data. Additional research into the strength of relationships between those receiving commuted sentences and race need to be completed however, before a statistically significant conclusion can be reached across all ethnic groups in the sample.

Criminology and the Use of Statistical Evidence

Words: 940 Length: 3 Pages Document Type: Essay Paper #: 90843203

Criminological Theory and Statistical Data

Introduction

Criminological theory is not always based on evidence—that is, on statistical evidence. Sometimes it is based on ideas that seem logical at the time. Theorists will notice correlations in the ways in which crime emerges in certain communities and they will base their theories of crime on these observances, though no statistical evidence is actually accumulated to verify the theory. The theory simply makes sense from a logical or rational point of view and in this manner it can be promoted. Its basis of evidence is qualitative (i.e., content-related, conceptual or thematic) rather than statistical and empirical (i.e., data that can be measured, quantified and verified through testing). Broken Windows Theory is one example of criminological theory that was based on qualitative assessments rather than on statistical data (Jean, 2008). While the theory has been embraced over the years since it was first developed,…… [Read More]

ANOVA Can Best Be Described as Statistical

Words: 642 Length: 2 Pages Document Type: Essay Paper #: 86066002

ANOVA) can best be described as statistical analysis of data with a variety of different variables and variations and is oftentimes used in a medical and professional research and practices environment. Using ANOVA in research is a commonplace technique, but there are some disadvantages to this usage; the application of the analysis is often conducted in applications where it is inappropriate (Patel, Naik, Patel, 2015). Ensuring that ANOVA is used in the appropriate manner, and that it is applied in situations that call out for ANOVA requires understanding and comprehension exactly what ANOVA does and how it is used in research. The Patel (2015) concluded that "conceptual understanding and application of ANOVA and Post hoc test was lacking among bio-medical research" (p. 117). Developing the required understanding will assist the researcher(s) in implementing data analysis that will create a more valid and reliable study, along with results that can be…… [Read More]

Pearson r can tell us how strong the relationship is between two variables. The closer to 1, the stronger the relationship is and the closer to 0 the weaker the relationship is. If the Pearson r value is positive, the relationship is direct, and if negative, the relationship is inverse. In our hypothetical case study, the r value is negative and thus the older a worker gets the less engagement they demonstrate with the customers.

The chi-squared measure indicates how likely two variables are to be independent of each other (such as a person's favorite color and their last name) or dependent on each other (such as a person's race and his/her income). In this case, the value of chi-square at less than .05 indicates that the possibility that gender and customer engagement are randomly related is less than 5%.

Sustainability

Perceptions of sustainability improved slightly in the experimental group, however this change was not significant and the null hypothesis is not rejected (p=.32). The flag exposure did not improve perceptions of sustainability to a noteworthy degree.

Traditionality

Once more, there was statistically significant change -- and once more, it was so significant that the null hypothesis would be almost certainly rejected (p-value is effectively 0) -- but that this change was again in the wrong direction. Flag perception (or possibly the confounding variable of healthy eating desires, though that seems far less likely for this item) is correlated with a significant decrease in perceptions of traditionality, not an increase as predicted in the alternative hypothesis. The null hypothesis remains in place, therefore.

ANOVA) is a combination of statistical techniques in which a variance in a certain variable is divided into parts characteristic to various sources of variation. ANOVA provides a statistical evaluation of whether or not the ways of several congregates is equal and generalizes t-test of more than two groups. This technique is usually beneficial in comparing two, three, or more means of given tests, which can help businesses to identify trends. Moreover, the statistical technique is a practical tool that can be used to compare two groups either with a single independent variable or with two independent variables. It can also be used to assess differences in worker responses to employee engagement in a certain organization or to determine variations in employee productivity on specific work shifts depending on certain variables. As a result, analysis of variance is considered as a tool that can be used in manufacturing to improve…… [Read More]

Map of Prescription Filling at an HMO and SIPOC for Problem Analysis (Bertrand

Filling prescriptions and the estimated time each activity takes consist of four steps in most pharmacies (Bertrand, 2012). The first is entering the prescription when received from two to 10 minutes. It may be longer according to the duration of the billing process and the ease or complicatedness of the prescription. The second is filling the medication, which takes from three to 15 minutes or longer, depending on the type of prescription and its storage or if it has to be reconstituted or compounded. The third is checking it, which can take between three and 10 minutes. The pharmacist makes sure it is the correct prescription, the dose, the interactions and the genuineness of the prescription. The duration depends on the prescription and the patient's history and profile. And the fourth is the release of the prescription.…… [Read More]

Multivariable Statistical Control Charts

Hoteling T^2 Control Charts

Multivariable statistics is an aspect of statistics that involves analysis of more than one variables. In other words, the multivariable analysis is concerned with the statistical analysis of more than one variables how they are related to one another. Some problems involve using the multivariable data using multiple regression or linear regression, and one of the aspects of the multivariable analysis is an area that involves analysis of quality control using the linear regression. Contrary to the univariable analysis that uses two variables, the multivariable analysis uses two or more independent variables or dependent variables. The concept independent variables are the variables manipulated by the researcher to carry out the analysis. With this control, the researcher will be able to correlate the dependent and independent variables. However, the manufacturing companies are increasingly using the multivariable statistics to enhance product quality. In the contemporary manufacturing environment, increasing…… [Read More]

The Use of Probability Values in Statistical Testing

Words: 848 Length: 2 Pages Document Type: Essay Paper #: 61379916

Suitable P-Value for a Clinical Trial

Statistical testing to determine whether results are significant is extremely useful in all types of research. In most cases, where a significant level, or p-value, is being chosen, a p-value of .05 is deemed to be sufficiently accurate. However, while this may be suitable for many types of research, it may be argued that in clinical trials from drugs, a lower p value may be more appropriate, due to the nature of the research. To understand this, it is necessary to understand what the p-value is, what it signifies.

The p value gives a probability, but is easy to misunderstand, as it indicates the level of support for the null hypothesis, with the probability level used to determine whether to accept or reject the null hypothesis. The p-value provides the probability of gaining an effect at the same level if the null hypothesis is…… [Read More]

Local merchants felt this average was too high for their area. They contracted an agency to conduct a study. A random sample of 60 consumers was taken at a local shopping mall the Saturday before Mother's Day and produced a sample mean amount of $106.27. If ? = $39.50, does the sample provide sufficient evidence to support the merchants' claim at the 0.05 level of significance?

The methods section should follow from the hypothesis, clearly laying out the exact tests, procedures, and participants used in the study. The methods section should not be lengthy, but should allow any reader to replicate the study if they seriously question the results. Most importantly, it should walk the reader through the study step-by-step, without getting too wrapped up in the details. Data on numbers of participants and demographic variables are important for controlling sampling errors between replications and reducing the chance that results will be overextended to all populations. ny instruments or manipulations borrowed from previous literature should be cited in the Methods section.

As an illustration, consider this statement of the hypothesis in a study done by Burger et al. (2001): "[S]mall, ephemeral increases in liking toward a stranger will lead to an increased likelihood of complying to a request from that person." The preceding section of the article -- the introduction -- cited numerous examples that provide evidence that this hypothesis might be supported, such as findings that repeated exposure increases interpersonal liking, or that people are more likely to donate to a cause (e.g. comply with a request for money) if they are given a "free gift" (to increase liking). The authors were careful to draw attention to the negligible, marginal character of the degree of liking -- going so far as to call it a "mindless heuristic" -- suggesting that a null outcome for this study was perfectly conceivable, if in fact the increase in liking had no direct effect on compliance with a request. And their hypothesis made fully testable experimental predictions -- using a process that has previously shown to increase the degree of liking between strangers, how much does this process affect the number of complied-with requests vs. refusals?

The methods section should follow from the hypothesis, clearly laying out the exact tests, procedures, and participants used in the study. The methods section should not be lengthy, but should allow any reader to replicate the study if they seriously question the results. Most importantly, it should walk the reader through the study step-by-step, without getting too wrapped up in the details. Data on numbers of participants and demographic variables are important for controlling sampling errors between replications and reducing the chance that results will be overextended to all populations. Any instruments or manipulations borrowed from previous literature should be cited in the Methods section.

Basic ANOVA Study

ANOVA Test

The focus of this proposal is to use the analysis of variance (ANOVA) to test whether the video games influence behavior. There has been a general public concern on the risk factor of video games on the youth's behavior especially children under 18 years of age. Science Daily (2013) shows that video games are the risk factors to aggression and criminal behavior. Despite this assertion, there still a paucity of valid and reliable academic research on the risk factors of video games on behavior. This proposal attempts to fill the gap by using ANOVA to test whether the video games influence behavior.

Do video games influence the aggressive or criminal behavior?

ANOVA is an appropriate statistical test for the proposal because it will be used to test for a significant difference of two means. Using the ANOVA for the proposal, the researcher will be able to produce valid…… [Read More]

The researchers were able to conclude that the finding was significant because the Statistical value (F) had a p-value of less than .05, which is the cut-off point for significance. Consequently, they can conclude that there is a significant difference between the control and treatment groups over time.

statistics statistics and inferential statistics.

Descriptive statistics and inferential statistics are used for different types of designs. For example, correlational studies will utilize descriptive statistics to measure a set of data's central tendency along with the way variables vary and relate to one another. A Pearson r would be a type of descriptive statistics test conducted to evaluate the strength of the relationship or if there relation goes in any one direction but descriptive statistics can also be used in causal-comparative design studies to measure data variability (Statistics for the non-statistician, n.d., p. 70). Inferential statistics on the other hand are used to compare means (typically a t-test is conducted) and statistical significance is determined by whether the p value is > or < than alpha (commonly .05) (Statistics for the non-statistician, n.d., p. 61).

First of all only a scant few of these Veterans groups will acknowledge the "promise" of free health care; for the most part these groups will tout the benefits already promised by the Veterans Administration and assert that cuts in these benefits are the same a broken promise-or contractual breach in legal terms. The idea of the United States military making a "promise" or forging a legally binding agreement between individual veterans or groups of veterans is barred by the United States Constitution. As will be demonstrated in the Literature eview, specific Constitutional language from Article I give Congress and only Congress the express authority to make laws and regulations pertaining to the armed forces.

Where the hypotheses were well-followed throughout the text, the conclusion ignores the relevance of these factors to the delay experienced by patients in seeking treatment. Instead of developing a correlation between the identified behavior and the subject matter, importance of creating awareness among the general public was the highly emphasized. Furthermore, the responsibility of nurses and government authorities in this regard, was also discussed.

Limitations

The study itself had a rather limited scope. Selection of convenience sample along with a particular racial background and non-inclusion of patients who died within hours of reporting AMI acted as major drawbacks. Secondly, a selection of considerably small sample also raised questions on the reliability of the sample.

Workers With in Small Firms

Chapter I outlines the problems this research aims to address, namely an information gap that may, if filled, enhance employment for potential and existing workers with disabilities. This chapter defines the problem background, purpose of research, theoretical framework through which conclusions will be drawn from survey data gathered in the field, the research questions the survey instrument seeks to answer, the definition of terms those questions employ and limits and delimitations of the intended research. Once those parameters are outlined, the claim this argument attempts to support, that closing a gap in information describing satisfaction and productivity for workers with disability in small firms below conventional definitions of 500 workers or less may improve employment for a historically marginalized population, leads to conclusions that thus inform the subsequent methodological and analytical chapters.

Analysis of Variance (ANOVA)

Analysis of variance is a term used in statistics which involves a collection of statistical models and procedures that are associated with them where the observed variance in a particular variable is partitioned into components that can be attributed to different sources of variations. It is therefore a statistical technique that is useful for evaluation whether there are differences between average values or mean across several population groups. This model also entails that the response variable is continuous in nature while the predictor variables can be categorized. For there to be a test for statistical significance between means then there has to be a comparison i.e. analyzing variances hence the name of the model. There are various concepts in variance analysis these are; the partitioning of sums of squares .at the core of variance analysis is the fact that variances can be divided or…… [Read More]

However, there are those who feel that the issue is beyond our human capabilities and that we are playing with fire. There have been many surveys conducted on public opinion concerning the issue. Some of the studies have been formal, conducted by the research community, and others are informal, conducted by parties such as the news media. Many of these studies failed to separate answers according to gender, age and other demographic issues.

To test whether the research results are statistically significant an appropriate test of statistical significance should be run. A chi-square "goodness-of-fit test is used to determine whether a set of proportions have specified numerical values" (Hypothesis testing, 2009, Quick MBA). However, in this specific instance, since it is likely that multiple batch tests for defects will be run, an ANOVA test would be more appropriate: "The primary purpose of ANOVA is to test for differences between multiple means. Whereas the t-test can be used to compare two means, ANOVA is needed to compare three or more means. If multiple t-tests were applied, the probability of a TYPE I error (rejecting a true null hypothesis) increases as the number of comparisons increases" (Hypothesis testing, 2009, Quick MBA).

Correlation of Seller's ating (0.30) to Auction's Highest Bid correlates at the.01 level of confidence.

Conclusions

The conclusion seems incomplete as negative ratings of online sellers would need to strongly correlate with low bidding to make adverse selection completely proven in this study. The fact that there is no strong correlation in this study to negative rankings, a foundational element of asymmetric information, makes one see the research as incomplete in its design.

The research design is incomplete in that it does not capture sales lost due to prices being too high and statistically proving the full hypothesis of adverse selection.

mortgage default (Elul, Souleles and Chomsisenghept). This model suggests that home owners should only ever default if they have negative equity in their residence. If there is negative equity, then there would be an incentive for the borrower to walk away from the property. However this also does not consider subsidiary effects such as the impact upon the person's credit or the possibility that the property could regain equity in the medium or long-term. Furthermore, other researchers have also proposed that other factors such as being illiquid would also provide a motive for someone to default on their mortgage. A combination of these two variables would also act to amplify the incentive to voluntarily default; and of course being so illiquid that there is no possibility to make a mortgage payment virtually guarantees that a default will occur.

Data interpretation is an important exercise that comes after the data is analyzed. It helps to draw conclusions from the data itself. In the data interpretation process, it is possible to tell whether the hypothesis has been accepted or not. It is also possible to know how the sampling or data collection methods affected the results that have been collected. Data interpretation also helps to provide the answer to the research question. This is because the data collected is integrated with the hypothesis in order to find an answer to the initial research question. It is also learnt that data interpretation helps to discuss the summaries and data presentation methods in order to know whether they were appropriate for the type of data collected. Predictions regarding the elements of uncertainty that result from the data collection exercise and data presented can then be discussed and analyzed to acknowledge the role that variation plays in hypothesis testing. The inferential analysis was conducted in order to help draw conclusions about the results of the small data collection exercise. The statistical tests that have been used which are the ANOVA and t-test also show the relationships that exist between the variables. Data interpretation is also an essential step towards making evidence-based predictions for future related research questions.

Chicago is a famously polarized city in terms of racial and class tensions, thus focusing on community needs generates an important sense of unity between members of the police force and specific community members. It has been praised for its effective implementation of POP. It recently began a much-heralded initiative to bring POP to its public school system. Killings occur with alarming regularity in the city's public schools. There were 67 deaths during the first half of 2007 -2008 academic year alone, the year that POP was instituted to combat the problem within the school system. "If this doesn't sound bad enough, the 67 doesn't include the hundreds of students who were shot or beaten but managed to survive" (Waldek 2009). To implement POP, the Chicago police first surveyed the assessed patterns of school violence and causation possibilities. Over 500 students who suffered school violence were studied. "The students at the highest risk of violence, by statistics, are most likely to be black, male, without a stable living environment, in special education, skipping an average of 42% of school days at neighborhood and alternative schools, and having a record of in-school behavioral flare-ups that is about eight times higher than the average student" (Waldek 2009). Violent outbursts also tended to occur within a relatively narrow window of opportunity, either two hours before or after school and

There are many more challenges involved in the development of forecasting models and the development of predictive analytics as they relate to the impact of both CoffeeTime's and competitor's advertising spending. The following are additional considerations in the development of more thorough predictive analytics and statistical forecasting models of the Indian market for CoffeeTimes' beverages and sandwiches:

Advertising spending increasing overall market growth or cannibalizing competitive sales? This is a major question that needs to be addressed through more econometric modeling, specifically looking at the aggregate impact of industry-wide spending on increasing the total market size for served coffee in key segments of the market vs. forcing consolidation of the market and cannibalization of sales. This dichotomy of market direction could best first be tested from the standpoint of attempting to predict aggregate demand and consumption for coffee in India for three to five years. Next taking the approach of…… [Read More]

Effectiveness of Restorative Justice Practices

Words: 3001 Length: 10 Pages Document Type: Essay Paper #: 43130748

Restorative Justice Approaches Reduce Youth Offending

Restorative justice is a new paradigm within the criminal justice, particularly in the context of youth offenders. The philosophy behind restorative justice is to consider the juvenile's interests to develop them into beneficial citizens, and it augments the principle behind juvenile justice and corrections. Restorative justice approaches provide the juvenile justice system with leniency when approaching youth offenders while at the same time holding the offenders accountable through rehabilitative approaches. The core elements of restorative justice include rehabilitating and restoring the youth offender, restoring and making restitution to the victim, and restoring the entire society. Programs employed in the restorative approaches can apply in both community correction centers and institutional treatment programs. Juvenile court and statutes aim to protect the child and not to punish them (Latimer, Dowden, & Muise, 2005).

However, juvenile justice has evolved over the centuries, and this has seen to…… [Read More]

In interacting, factors may also modify each other:

nurse who might return to work for a higher salary might decide to do so only later when her children are older. The incentive of salary is therefore modified by the factor of young children.

The table is significantly complicated by the inclusion of more than two factors:

Any combination of the factors could result in the majority of nurses returning to work. Individually, each nurse has his or her own motivations for doing so.

The iterative proportional fitting procedure can be used to calculate expected frequencies.

Note: pecifically, the indication of this study is that nurses would return to work were certain factors in the work situation to change. pecifically, the highest frequencies are assigned to work load and hours. These are also the two most common factors in causing burnout and stress in the profession. Concomitantly, if inactive nurses were…… [Read More]

Penis

Since the beginning of time the male species has had an obsession with that part of the personal anatomy known by its Latin root as the "tail"; or today known as one's pecker, "wankie," monkey, and a host of other rather humorous titles. Somewhere, however, in creating the world God must have became confused when creating man as, and being politically correct, he/she placed the tail on the man's front side and on the animals' rear side -- or maybe God just had a bad day on his/her day of creation. Regardless of what one wants to call his penis or tail, history has proven that man's obsession with the penis is ever ending. Simply consider the folklore surrounding John Dillinger whose penis was reportedly over 20 inches. If medical science were correct it would likely have taken Dillinger 20 minutes to get enough blood circulating in his penis…… [Read More]

Hering, Pritsker, Gonchar, & Pilar (2009), the statistical procedure used examined students who were from Tirat HaCarmel, Israel. These students were studied at the town's health and child care center. Non-obese children were the control group, and they were matched up with obese children who were also studied. The match-ups included both gender and age. Then, children were divided even further into specific groups by age. These were 4-7 years, 8-11 years, and 12-18 years (Hering, et al., 2009). Four different criteria were used over a period of two years in order to get results that were statistically significant. These criteria were visits to the emergency department, visits to the clinic, medication usage, and whether the child was hospitalized (Hering, et al., 2009).

The study reached the conclusions that there were more than 4000 children treated at the care center, and there were 363 children who were obese and who…… [Read More]

Assessment of Technology Adoption By

Small and Medium-Sized Logistics Providers

The adoption of technologies for streamlining and unifying supply chains globally continues to show promise as a means to take supplier coordination and product quality to a new level transparency and velocity. Of the many aspects of technology adoption throughout supply chains, the contributory effects of information and communication technologies (ICT) in third party logistics providers (3PL) has become a leading indicator of an industry's ability to adapt to turbulent market conditions (Brah, Lim, 2006). Despite the many benefits of adopting technologies in 3 PLs and across supply chains, there are many factors that limit their use. The study Technology Adoption in Small and Medium-Sized Logistics Providers (Evangelista, McKinnon, Sweeney, 2013) highlights the challenges small and medium logistics providers face in adopting ICT-based solutions throughout their businesses.…… [Read More]

Organizational Commitment

The author of this report is asked to compare and contrast three articles relating to organizational commitment. The three articles in question are all heavy-hitters on the topic and all emanate from the academic and peer-reviewed scholarly spheres. The first was the 2002 treatise offered by Swailes. This more dominant offering relating to organizational commitment will be compared to the 2008 work or ikettta and the 2006 work of Harrison et al. While there are definitely differences in the options and conclusions made by the three studies, they also share very strong corollaries.

Questions Answered

Swailes started off by covering the early viewpoints of organizational commitment dating back to the work of Fayol in the 1940's. He also covered Weber's work in 1947 as well as other works through the 1970's, 1980's and 1990's. The earlier work that Swailes seized on and identified as pivotal when speaking of…… [Read More]

patients undergoing mechanical ventilation contract Ventilator Associated Pneumonia (VAP). This acute medical condition always results in increased death rates and associated medical costs among patients. This article reviews several literatures that try to enlighten masses on the diagnosis, medical treatments and VAP prevention methods. In addition, this article outlines recommendations medical practitioners can implement in their daily practices to curb VAP and offers an insight on controversies that usually arise during VAP diagnoses, treatment plans and prevention methodologies. This article defines VAP to be the causative agent of approximately 25 to 54% mortality rates among patients undergoing mechanical ventilation in ICUs. Factors responsible for VAP among patients include patients' population in ICUs, hospital stay durations and antimicrobial treatments. Even though antimicrobial medications are confirmed to reduce VAP casualties, further studies should be undertaken such as the ones outlined in the literatures below to help in early identification and treatment of…… [Read More]

Ethical Communication

The Definition of Ethics

In practically all areas of society ethical subjects are rapidly increasing. Professionals in the health field struggle with ethical questions in relation to abortion, transplants, birth control, informed consent, life-support systems, malpractice suits, patient privacy, human genetics, and high costs of insurance, as well as care on the whole. Ethical matters in relation to nuclear power accidents, oil spills, disposal of industrial waste, defense weaponry, lead and asbestos poisoning, acid rain, as well as ecological balance challenge those in technology, science, and industry. People in the political ground deal with ethical queries in relation to unemployment, homelessness, foreign policy decisions, Social Security, welfare reform, electioneering costs, law enforcement practices, Central Intelligence Agency (CIA) activities, racial and gender discrimination, immigration control, drugs, crime, and lobbying actions. The legal profession is blamed of unethical customs like engaging in doubtful plea-bargaining practices, motivating a harmful litigious spirit,…… [Read More]
