Dr. Hindsmith has developed a new test for IQ. When Dr. Hindsmith distributes the new test to college students and finds that the students score the same every time they take the test, but that the test does not predict how they perform on other IQ tests. Dr. Hindsmith's test appears to have reliability but not validity. True or false?

Answers

Answer 1

Answer: True

Explanation:

Reliability is the factor that defines measure consistency in test, research or other measurements.It depicts the extent to which the measure is stable for different participants and variable time period.

Validity is the factor that describes accuracy and preciseness of the test.It reflects that the test is measuring the claimed or intended measure.

According to the question,Dr. Hindsmith test is reliable but does not display validity as score of students is consistent in test but it does not define their performance in other test.

Thus, the given statement is true.

A hockey player who was playing in the final game of the season before a hostile crowd in the opponent’s packed stadium had an opportunity to get his team into the playoffs, but he missed a shot into an open net as the horn sounded, ending the game. As the crowd cheered and jeered, the puck bounced back to him and he shot it in anger toward the stands. A fan who had been looking the other way turned back toward the rink just in time to be struck in the face by the puck. He suffered a broken nose and a severe gash under his eye. After the game, the league commissioner fined the player for violating league rules by intentionally directing the puck out of the playing area. If the fan sues the player for battery, will the fan likely prevail?

Answers

Yes the fan would prevail it, because the player knew that it was certain that a fan would be hit by the puck. So in this is very clear how the the fan would know that, because both of them already knew it.

Which schedule of reinforcement presents the reinforcer at the end of a predetermined interval, contingent on the number of responses emitted during the interval being greater than a gradually increasing criterion based on the individual's performance in previous intervals?

Answers

Answer:

Differential Reinforcement Ratio of High Rates

Explanation:

Differential Reinforcement Ratio of High Rates is a schedule of reinforcement when reinforcement is provided at the end of a predetermined interval, contingent on the number of responses emitted during the interval being greater than a gradually increasing criterion based on the individual's performance in previous intervals, it is contingent upon emitting at least a certain number of responses in a certain period of time. When reinforcement is higher than a predetermined criterion, it produces a higher rate of return.

Final answer:

The schedule in question is a variable interval schedule, where reinforcement is given after fluctuating time intervals contingent on the number of responses being above a variable criterion. This differs from a fixed interval schedule, which provides consistent reinforcement after set time periods.

Explanation:

The schedule of reinforcement described in the question, where a reinforcer is presented at the end of a predetermined interval based on the number of responses being greater than a gradually increasing criterion from previous intervals, is known as a variable interval schedule. This type of schedule presents the reinforcement at inconsistent time intervals, but the intervals fluctuate around a mean time frame. The behavior is reinforced, but not after every response, and the reinforcement is contingent upon the number of responses exceeding a variable criteria. This makes each reinforcement unpredictable, boosting the likelihood that the desired behavior will be maintained over time.

Unlike a fixed interval schedule which delivers reinforcement after a set amount of time regardless of the number of responses, the variable interval schedule requires the reinforcer to be presented after an interval that changes based on the individual's performance during the past intervals. This reinforces a steady rate of response without the 'scalloped' pattern that is typically found in fixed interval schedules, where there is often a pause after a reinforcement is given.

Do you believe the Elizabethan Poor Laws still influence some of the government assistance that is provided today in the United States?

Answers

Answer:

The Welfare State, as many authors maintain, is nothing other than the continuation of the Liberal State. That is to say, its intervention in the economic and social areas was only due to a momentary need to manage capital in order to favour one sector and avoid stopping the development of the capitalist state and its potential growth.

It is a measure that has certain reminiscences to those implemented in the 1600s with the Law of the Poor, which sought to change the idea of society and help the most needy.

The role of the nations, at that time, was to provide the best quality of life for men and women but without discarding the so-called vagrants, who later would collaborate with the labor force to grow the factories and companies.

All citizens have the same right to satisfy their needs as humans and enjoy the fruits of their labor. That is why governments, put in place programs, services and social plans that try to solve the problems of poverty, as well as provide help to anyone who seeks to collect their pension, have a home of their own and provide education to their children. It is these actions that make the social welfare of a nation real.

It was John. M. Keynes, who after the economic depression experienced in 1929, set in motion the Welfare model, leaving behind the current model of liberalism.

The Keynesian or Welfare State, postulated that one should intervene in the economy and society, with a view to complementing the functioning of the market, guaranteeing a minimum of basic welfare for all of society.

The new implementation helped the urban society to improve its quality of life and the welfare of the citizens.

This new Keynesian model placed four important factors within society, managed by the government: health, education, pensions and social services.

In this sense, the United States is not an exception when through numerous legal principles it seeks to maintain the welfare state among the most disadvantaged population, but always providing development opportunities without falling into the humiliating categorization and classification that characterized, and was highly criticized for that, the law of the poor.

Which of the following is an environmental policy based on tradable pollution permits?

A. ignoring pollution and letting private markets operate without government interference
B. allowing automobile drivers to buy and sell the right to a certain level of automobile emissions
C. a charge of $0.10 to automobile drivers for a given level of emitted emissions
D. paying automobile drivers $0.10 for each 10% reduction in automobile emissions

Answers

Option B

Allowing automobile drivers to buy and sell the right to a certain level of automobile emissions  is an environmental policy based on tradable pollution permits

Explanation:

It has been declared that tradable pollution permits accomplish the fancied level of pollution limitation at an optimal cost to society. They give groups a legitimate right to pollute a specific cost per set period. Firms that contaminate less can then sell their unused pollution privileges to firms that pollute more further. The purpose of this is that polluting firms and public means differ in their capacity to reduce their pollution –Consequently, tradable pollution permits can be a cost-effective way to reach a decline in overall pollution.

Final answer:

The environmental policy based on tradable pollution permits is allowing automobile drivers to buy and sell the right to a certain level of automobile emissions. In this system, firms are allocated emissions permits up to a specified limit and can trade permits with each other.

Explanation:

The environmental policy based on tradable pollution permits is option B: allowing automobile drivers to buy and sell the right to a certain level of automobile emissions.

In a tradable permit system, the government sets a limit on the amount of a pollutant that can be emitted. Firms are allocated emissions permits up to the specified limit. If a firm needs to emit more, they can buy permits from other firms that have excess permits. This allows firms to trade permits according to their needs and incentivizes them to reduce their emissions.

For example, in a scenario where ten firms each hold 1,000 permits for sulfur dioxide emissions, they can trade permits to achieve their total emission limit.

A firm with excess permits can sell them to another firm in need, incentivizing the reduction of emissions. This system ensures that the overall pollution level remains within the specified limit while allowing flexibility for firms to manage their emissions.

The bedrock of our democracy is the rule of law and that means we have to have an independent judiciary - judges who can make decisions independent of the political winds that are blowing.

Answers

Answer:

Given the quote, the independence of the Judiciary means the ability to carry out their functions without any external interference either from other branches of government or government institutions. The Judiciary is a branch of government saddled with the responsibility of Implementing and interpreting the laws made by the Legislative branch.

Judges are ministers in the temple of justice and must not only ensure justice is done but seen to be done. To achieve this, the judiciary must be guarded against external interference for the benefit of the people.

The Judiciary is the"bedrock" of democracy saddled with the function of dispute resolution between aggrieved parties. Its importance comes to play where the parties are treated fairly by deducing the issues and applying the relevant evidence to arrive at a just conclusion.

It is of utmost importance as it makes sure the Judges uphold the principles of the rule of law without bias but based on the  provision of law without any external control from other bodies.

Whereas the American system of government is characterized by federalism, most nations are governed by __________.

Answers

Answer: A unitary system of government

Explanation:

A unitary system of government is sovereign state governed as a single entity. This is what most nations are governed by.

Whereas the American system of government is characterized by federalism, most nations are governed by unitary systems.

In a unitary system, power is concentrated in the central government, with little or no power given to regional or local governments. This allows for a more centralized decision-making process and uniform policies across the entire country. Unitary systems are common in countries where there is a strong sense of national unity and a desire for a uniform national identity.

Examples include France, China, and Japan. In contrast, federal systems, like the one in the United States, divide power between a central government and individual states or provinces, allowing for more regional autonomy and a greater distribution of power.

Explanation:

 Culture is the term that is used to refers to the group of people that encompasses the various types of norms and also the social behavior which include the beliefs, capabilities, knowledge and the laws in the human society.

The culture is one of the main factor that helps in providing the various types of economical and the social benefits and it also enhance the living quality.

According to the given question, the culture is one of the set of assumptions and the understanding that is specifically shared in the country and the ethic group.

 Therefore, Culture is the correct answer.

Final answer:

The term in question refers to principles or morality, which encompass a society's collective beliefs and values, often described as the political culture in the context of a country. These include shared ideologies, social norms, collective identity, and traditions.

Explanation:

The blank in the question refers to a society's shared, stable beliefs about what is good and bad, or right and wrong. This concept is often encapsulated in the terms principles or morality. These are the assumptions and convictions held by an individual, group, or culture about the truth or existence of something. In a more specific sense, referring to a particular country, we use the term political culture, which encompasses the collective ideologies, values, beliefs, norms, assumptions, and patterns of behavior that characterize that country.

Social norms also play into this definition as the ways of thinking, feeling, or behaving that are shared by group members and perceived by them as appropriate. Altogether, this set of shared knowledge constitutes the cultural foundation - including a collective identity, common language, and a cherished set of traditions - that shapes how members of the group understand the world and interact within it.
