As part of the study described in Problem 6, investi- gators wanted to assess the accuracy of self-reported smoking status. Participants are asked whether they currently smoke or not. In addition, laboratory tests are performed on hair samples to determine the presence or absence of nicotine. The laboratory assessment is considered the gold standard, or the truth about nicotine consumption. The data are shown in Table 5-13.
a. What is the sensitivity of the self-reported smok- ing status?
b. What is the specificity of the self-reported smok- ing status?

Answers

Answer 1

In assessing the accuracy of self-reported smoking status, the sensitivity and specificity are key measures. Sensitivity refers to the proportion of true smokers correctly identified as smokers by self-report, while specificity refers to the proportion of true non-smokers correctly identified as non-smokers by self-report.

a. The sensitivity of self-reported smoking status is the proportion of true smokers correctly identified as smokers. It can be calculated by dividing the number of true smokers who reported smoking by the total number of true smokers. Sensitivity = True Positives / (True Positives + False Negatives).

b. The specificity of self-reported smoking status is the proportion of true non-smokers correctly identified as non-smokers. It can be calculated by dividing the number of true non-smokers who reported not smoking by the total number of true non-smokers. Specificity = True Negatives / (True Negatives + False Positives).

To calculate the sensitivity and specificity, the data from Table 5-13 should be used. The true smokers correspond to the participants with a positive nicotine test result, while the true non-smokers correspond to those with a negative nicotine test result. The true positives represent the participants who reported smoking and had a positive nicotine test result, while the true negatives represent those who reported not smoking and had a negative nicotine test result. The false positives and false negatives can be calculated by subtracting the true positives and true negatives, respectively, from the total number of participants.

By calculating the sensitivity and specificity using the appropriate formulas, we can determine the accuracy of self-reported smoking status in this study.

Experimental research requires only one of the following. Which one is an essential component of an experimental study? Manipulating an aspect of the environment

Answers

Manipulating an aspect of the environment is an essential component of an experimental research.

In experimental research, the manipulation of an aspect of the environment is crucial because it allows researchers to investigate causal relationships and determine the effects of specific variables on the outcome of interest. By deliberately changing one aspect while keeping other variables constant, researchers can isolate the impact of the manipulated factor and observe its influence on the dependent variable.

This manipulation provides control over the experimental conditions and helps establish cause-and-effect relationships. Without manipulation, researchers would be unable to establish a direct link between the independent variable and the observed changes in the dependent variable, undermining the validity and reliability of the study's findings.

Answers

a) The probability that an American had a job in July 2017 is approximately 91%.

b) The probability that all 5 randomly selected Americans were unemployed is approximately 0.0000066.

c) The probability that all 5 randomly selected Americans had a job is approximately 62.4%.

d) The probability that at least one person had a job from 5 randomly selected Americans is approximately 99.99934%.

e) The probability that all 15 randomly selected Americans had a job is approximately 30.4%.

The probability that an American had a job in July 2017 can be calculated using the complement rule. Since the unemployment rate for July 2011 was 9%, it means that 91% of Americans had a job. Assuming that the likelihood of unemployment is independent from person to person, the probability that an American had a job in July 2017 is 91%.

To calculate the probability that nobody had a job from 5 randomly selected Americans, we can use the probability of unemployment. Since the unemployment rate is 9%, the probability of one person being unemployed is 9% or 0.09. Assuming independence, the probability that all 5 randomly selected Americans were unemployed is calculated as:

= (0.09)^5 = 0.000006561, or approximately 0.0000066.

The probability that everybody had a job from 5 randomly selected Americans can be calculated using the complement rule. Since the probability of one person having a job is 91% or 0.91, the probability that all 5 randomly selected Americans had a job is:

= (0.91)^5 = 0.6240311, or approximately 0.624.

To calculate the probability that at least one person had a job from 5 randomly selected Americans, we can use the complement rule again. The probability that nobody had a job is 0.0000066, so the probability that at least one person had a job is:

= 1 - 0.0000066 = 0.9999934, or approximately 0.9999934.

The probability that everybody had a job from 15 randomly selected Americans can be calculated using the same logic as in part c. Since the probability of one person having a job is 91% or 0.91, the probability that all 15 randomly selected Americans had a job is:

= (0.91)^15= 0.3044247, or approximately 0.304.

Answers

According to the research on social distance rankings from 1920 to 2011, the group that was consistently ranked at the top of the social distance rankings was African Americans.

Social distance refers to the perceived degree of social separation between groups of people, such as races, nationalities, and religions. In the US, the social distance rankings were used to measure the degree of prejudice and discrimination against different groups. The ranking involves asking participants to indicate how comfortable they would be with different levels of social interaction with members of a particular group.

The rankings have been used to study prejudice against African Americans, Jews, Asian Americans, and other groups.
This means that people in the US were least comfortable with social interaction with African Americans compared to any other group over the past century.

This is indicative of the deep-rooted racism and prejudice against African Americans in American society. Despite some progress in civil rights and race relations, the persistence of social distance rankings indicates that much work remains to be done to overcome racism and promote social equality.

The model minority stereotype is one that is imposed on Asian Americans as a monolithic group, which is the majority of which are believed to have achieved success in educational and economic domains.

Some scholars argue that this stereotype has helped to create negative consequences for both Asian Americans and other minority groups, as it is founded on a false assumption that the Asian Americans experience uniform success. As a result of this stereotype, Asian Americans are often perceived as being hardworking and successful, which can create positive outcomes in the workplace and educational spheres.

Additionally, the model minority stereotype can lead to negative consequences for other minority groups because it suggests that if Asian Americans can succeed despite facing discrimination, then other groups should also be able to overcome obstacles. This is an inaccurate and unhelpful assumption as it ignores the systemic disadvantages that many other minority groups face.

In March 1995, a 27 year old man who had stolen a slice of pizza from a group of children sitting outside a pizza parlor became the first person to be sentenced to 25 years to life in prison under California's "three strikes and you're out". Enacted March 7, 1995, the law was reinforced November 5, 1995, by a constitutional amendment supported by 72% of California voters. The "three strikes" law is triggered by two past felony convictions. In this case, the defendant was convicted of "petty theft with prior felony conviction". He had already been convicted of robbery, drug possession, and riding a stolen motorcycle. a. It will cost the taxpayers of California about $26,000 a year to incarcerate the man. Is it worth it? Is it a wise expenditure of tax dollars? b. Is the punishment proportional to the crime or crimes? Should it be? c. Do you think "petty theft with a prior conviction" is a legitimate trigger of a "three strikes" law? d. There is no question that the offender was a criminal. He had a reputation for being a bully. Nevertheless, are "three strikes and you're out" laws an ethically defensible way of dealing with such criminals? Why or why not?

Answers

The value and wisdom of the expenditure depend on the priorities and perspectives of the society in question. Whether it is worth incarcerating the individual for 25 years under the "three strikes and you're out" law depends on societal priorities and perspectives,

a. From the perspective of a taxpayer, this expenditure might appear unnecessary. However, keeping in mind that the law is aimed to prevent future crimes, it is likely that the investment would be worth it.

b. The 25 years to life sentence seems harsh, but one cannot ignore the fact that this was not the defendant's first crime. He had already been convicted of robbery, drug possession, and riding a stolen motorcycle. Thus, it can be argued that the punishment is proportional to his criminal history. Whether the punishment should be proportional or not is a matter of debate, but the law has been passed and is in force.

c. It can be argued that petty theft with a prior conviction is not a severe enough crime to be a trigger for a "three strikes" law. However, it is important to note that the defendant had been convicted of other crimes before, including robbery and drug possession. Thus, the law was triggered due to his past crimes as well.

d. The "three strikes and you're out" law aims to prevent habitual offenders from committing future crimes. While the law might seem harsh, it is essential to consider the safety of the public as well. A criminal history that includes three serious felony offenses is significant evidence that the defendant is unlikely to change their behavior. In this sense, the law is ethically defensible.

Ethics as Virtue:

This approach to ethics is characterized by the idea that the key to ethical behavior lies in developing virtues such as honesty, integrity, courage, and compassion. Ethical behavior is seen as a result of having a virtuous character and making ethical decisions based on those virtues. Virtue ethics emphasizes the importance of personal responsibility and individual character in ethical decision-making.

Ethics as Consequence/Teleological/Utility:

This approach to ethics is based on the idea that ethical behavior is determined by the consequences of our actions. The ultimate goal of ethical decision-making is to maximize happiness and minimize suffering. This approach is also sometimes called teleological or utilitarian, as it emphasizes the idea that ethical decisions should be based on the overall good that they will bring.

Intuitionism/Gut Feelings/Moral Sense:

This approach to ethics emphasizes the role of intuition and emotions in ethical decision-making. According to this approach, our gut feelings and moral sense are important guides in determining what is right and wrong. Intuitionists believe that ethical principles are self-evident and do not need to be proven by reason or logic.

Answers

Psychologists determine whether a person has a psychological disorder based on whether his or her behaviour is maladaptive, causes emotional discomfort, and/or is socially acceptable or not. Therefore, the correct answer is option D

Psychologists evaluate various factors, including maladaptive behaviour, emotional distress, and social acceptability, to determine whether someone has a psychological disorder. By considering these aspects, psychologists gain a holistic understanding of an individual's functioning and can make an informed judgment regarding the presence of a psychological disorder.

Psychologists can assess the presence of a psychological disorder by considering if an individual's behaviour leads to emotional distress. For example, someone experiencing anxiety, depression, or other mental health issues may exhibit behaviour that reflects emotional discomfort, potentially indicating a psychological disorder. Additionally, psychologists may also evaluate the social acceptability of someone's behaviour to further determine the presence of a psychological disorder.

Psychologists employ different criteria, including socially inappropriate or maladaptive behaviour like aggression and impulsivity, to identify the presence of a psychological disorder. These behaviours can create difficulties in relationships and contribute to the assessment of a psychological disorder.

In summary, psychologists utilize a combination of factors, such as maladaptive behaviour, emotional discomfort, and social acceptability, to determine if an individual has a psychological disorder.

Institutional inertia makes social change difficult and yet we see a lot of social change in gender relations in many different social institutions. How do you explain this apparent contradiction? Discuss a few of the causal forces impelling change in ONE social institution of your own choosing.
Gender order Patriarchal marriage Breadwinner/housewife Partnership marriage Neotraditionalist

Answers

Social change can be difficult due to institutional inertia, but gender relations have changed in many social institutions. This contradiction can be explained by various causal forces, including economic, political, and cultural factors. One example of a social institution experiencing change in gender relations is the institution of marriage.

Institutional inertia refers to the tendency of social institutions to resist change, often due to established patterns of behavior, social norms, and power structures. Despite this resistance, we have seen significant social change in gender relations in many social institutions. This apparent contradiction can be explained by a number of causal forces that impel change in these institutions. These forces include economic, political, and cultural factors, among others. One example of a social institution experiencing change in gender relations is the institution of marriage. In the past, the gender order was typically patriarchal, with men serving as the primary breadwinner and women fulfilling the role of housewife. However, in recent years, there has been a shift towards partnership marriage, where both partners work

This change has been driven by various factors, such as increasing opportunities for women in the workplace, changing cultural norms around gender roles, and the rise of neotraditionalist attitudes towards gender and family. These changes have led to a significant shift in gender relations within the institution of marriage.In conclusion, while institutional inertia can make social change difficult, we have seen significant changes in gender relations in many different social institutions. These changes are driven by various causal forces and have led to a significant shift in the gender order within these institutions. The institution of marriage is one example of this shift, with a move away from patriarchal gender relations towards more partnership-based relationships.

Answers

With the exception of during recessions, workers in Canada are eligible for unemployment benefits for about twice as long a period of time as workers in the United States. As a result, workers in Canada experience a greater sense of job security.

In Canada, workers are eligible for up to 26 weeks of regular benefits and up to 50 weeks of extended benefits. After the regular benefits period has expired, they may be eligible for extended benefits, which will continue for up to 24 weeks, for a total of 50 weeks of coverage. Additionally, there are provincial and territorial benefits that can provide further assistance.In the United States, unemployed workers are typically eligible for up to 26 weeks of unemployment insurance benefits.

However, during periods of high unemployment, Congress may extend the duration of benefits. For example, during the Great Recession, unemployed workers were eligible for up to 99 weeks of benefits. Nonetheless, this extension was an anomaly, and the typical period of eligibility is still only 26 weeks.

Consequently, workers in Canada experience a greater sense of job security since they have a greater period of time to find a new job if they become unemployed. This sense of security may result in workers in Canada being more productive since they are not constantly worried about losing their job and being unable to provide for themselves and their families.

The statement "The process of cultural divergence most often occurs when new products/ideas spread from one country to another" is false because cultural divergence refers to the process by which a society or cultural group becomes increasingly distinct and develops unique characteristics separate from other societies or groups.

It typically happens when a society divides, expands, and some of its members settle in a new area, leading to the development of distinct cultural practices, beliefs, and traditions.

The spread of new products or ideas, on the other hand, may contribute to cultural diffusion, where elements from one culture are adopted by another, but it does not necessarily lead to cultural divergence.

Was the huge loss of American troops worth it to contain Communism in Korea and Vietnam based on the final outcome of those conflicts? Please explain why or why not?

What were the main reasons Saddam Hussein was allowed to stay in power at the end of the First Gulf War?

What were Osama bin Laden's main arguments against the United States that he used to justify his attacks?

Answers

The massive loss of American troops in Korea and Vietnam were not worth it in order to contain Communism because in the final outcome, the United States did not achieve its objectives in either conflict, which left both nations divided and with repressive regimes.

The purpose of the Korean War was to prevent the spread of Communism in Asia and to unite the nation under a democratic government, but the war ended with the division of Korea along the 38th parallel, resulting in the establishment of two separate nations that still exist today. Similarly, the Vietnam War was fought to prevent the spread of Communism in Southeast Asia, but it ended with a Communist victory and the unification of Vietnam under a Communist government. These conflicts caused massive loss of life and economic costs, but did not achieve their intended goals.In the First Gulf War, the main reasons Saddam Hussein was allowed to stay in power were due to a lack of international consensus on his removal and the fact that the objective of the war was to liberate Kuwait from Iraqi invasion.

The United States and its allies had the primary objective of removing Iraqi forces from Kuwait and restoring the territorial integrity of the nation, which was achieved through the successful conclusion of the conflict. While the international community agreed that Saddam was a threat to regional security, there was no consensus on the use of military force to remove him from power.Osama bin Laden's main arguments against the United States that he used to justify his attacks were that the US was occupying Muslim holy lands in Saudi Arabia, supporting Israel's oppression of Palestinians, and exploiting Muslim nations for their resources. Bin Laden argued that the US was waging a war against Islam and that Muslims had a duty to defend their religion from foreign aggression.

Therefore, He called for a global jihad against the United States and its allies and claimed that attacks on civilians were justified in the pursuit of this objective.

describe three (3) adaptations that have evolved in mesopelagic organisms to help them survive.

Answers

The adaptations that have evolved in mesopelagic organisms to help them survive are bioluminescence, large eyes and vertical migration

Mesopelagic organisms, also called "twilight zone" organisms, are those that live in the mesopelagic zone of the ocean. Because of the low levels of light, food, and oxygen, these organisms have evolved some adaptations to help them survive.

Here are three adaptations that have evolved in mesopelagic organisms to help them survive:

1. Bioluminescence: Many mesopelagic organisms produce light through bioluminescence. They use this light to attract prey, communicate with each other, and avoid predators. This adaptation helps them to survive by allowing them to find food and mates, and to avoid being eaten.

2. Large eyes: Many mesopelagic organisms have large eyes, which help them to see in low light conditions. Some species have even developed eyes that are sensitive to blue light, which is more abundant in the mesopelagic zone than other colours of light. This adaptation helps them to find prey and avoid predators.

3. Vertical migration: Many mesopelagic organisms migrate vertically, moving up to the surface at night to feed and returning to deeper waters during the day to avoid predators. This adaptation helps them to survive by allowing them to find food at the surface, where it is more abundant, and to avoid being eaten by predators that hunt in deeper waters.

Which emotion would be considered the most advanced for an infant to exhibit?
a. Interest
b. Fear
c. Sadness
d. Guilt

Answers

The developmental timeline of emotions, interest would generally be considered the most advanced emotion for an infant to exhibit compared to fear, sadness, or guilt.

In the context of infant development, it is important to note that emotions undergo significant development and maturation over time. Infants typically exhibit a range of basic emotions early on, such as happiness, sadness, anger, and fear.

However, the concept of guilt is typically considered to emerge much later in development, usually during the preschool or early childhood years.

Guilt is a complex emotion that requires a certain level of cognitive and social development. It involves an understanding of right and wrong, as well as the ability to reflect on one's actions and feel remorse for any wrongdoing.

Infants, especially in the early stages of development, lack the cognitive and moral capacities necessary for experiencing guilt.

Among the options provided, interest is often considered one of the earliest and most fundamental emotions that infants exhibit. It reflects their curiosity and engagement with the surrounding environment.

As infants explore their surroundings, they may display signs of interest, such as focused attention, exploration, and active engagement with objects and people.

Therefore, considering the developmental timeline of emotions, interest would generally be considered the most advanced emotion for an infant to exhibit compared to fear, sadness, or guilt.
