George Soros's contribution to the Center for American Progress identifies him as a philanthropist and financial backer, making a significant financial contribution to support the ideals of Progressive movements.
Explanation:In the context of the Center for American Progress, George Soros can be characterized as a philanthropist and a financial backer. A philanthropist is someone who seeks to promote the welfare of others, typically through the donation of money to good causes. George Soros pledged to contribute $3 million to the Center for American Progress, clearly making a substantial financial contribution to support the cause of this progressive public policy research and advocacy organization.
Moreover, it is important to consider this action within the realm of American progressive movements in history. Progressives at different times have sought to address social inequality, fight for individual rights, and empower the less fortunate. While methods differ, the commitment to these underlying ideals remains a central component of the Progressive ethos. Soros's financial support contributed to these Progressive efforts, marking him as an example of a financial backer in the greater historical context of Progressive movements.

A. Pavlov's experiments.
B. Watson's behaviorism.
C. a biopsychosocial approach.
D. the law of effect.
E. operant conditioning.
Answer:
C. a biopsychosocial approach.
Explanation:
First proposed in 1977 by G Engel a trendy approach emerged that contrasted with the biomedical model to treat better illness and understand how mind and body, as well as social aspects, can relate to all different levels as a unity.
It is the current and trendy approach in medicine.
The model takes into account the biological, psychological and social factors, that often went undermined in the treatment and prevention of minor and major diseases.
This framework enables physicians to better considerate how complex interactions of patients with their family, workplace and environment could have important consequences.
The biological factors were given still consideration but, other psychological factors influencing the appearance of disease were more deeply studies and the social and cultural aspects of any suffering were broadened.
The mind and body, as well as the environment, will always play a complex system where interactions will affect and the biomedical considerations will take increasingly conscience of the social and other aspects of any sickness and treatment.

A network in which communication passes from one person to another rather than being shared among members is referred to as a/anA) all-channel network.B) wheel network.C) tree network.D) chain network.
Answer:
Option D is correct. A chain network.
Explanation:
A good example of chain communication is a military division. Where the General talks to a Coronel (who is the next person in the line of command) and tells him that the troops must be ready for combat in 48 hours. The coronel then proceeds to communicate this information to his division.
This process usually takes more time, because usually, the people at the top of the chain doesn't talk much with the people at the bottom.

Answer:
The answer is: It is most likely that Dr. Matsuko is a developmental psychologist.
Explanation:
Developmental psychology is a field within psychology that focuses on changes and permanence in a person's growth and across the lifespan. It aims to understand and explain cognitive, emotional and behavioral development seeking for factors, both internal and external, that impact such development. Developmental psychology must also intend to optimize development, by transforming the theoretical insights into practical knowledge that can be used in a number of fields concerning child development.

Explanation:
African women who are trying to eliminate female genital cutting from their own societies are often not happy when American outsiders like Mary Daly and Alice Walker denounce the practice as a human rights abuse. Why?
Answer:
The correct answer is, Outsiders may not really know the meaning of said practices and it's cultural relevancy because they have not being directly affected by it.
Explanation:
Outsiders sometimes publicly condemn traditional rituals without being directly affected by those practices. Thus their critics and condemnations can sometimes be reductionistic and prejudiced.
What they American outsiders like Mary Daly and Alice Walker should be doing in order to help the African women who are trying to eliminate female genital cutting from their own societies is Listening. Listening to what those women has to say about the practices and how does it affect their lives.
Final answer:
African women working to end female genital cutting in their societies may be critical of outspoken American critics because their approach could lack cultural sensitivity and may not acknowledge the complex community and cultural dynamics involved. They prefer change from within, driven by empowerment and nuanced understanding of tradition, rather than external judgment and imposition of values.
Explanation:
African women who are trying to eliminate female genital cutting (FGC) from their societies may feel that American critics like Mary Daly and Alice Walker, who denounce the practice as a human rights abuse, do not fully understand the cultural context and complexities surrounding the tradition. Efforts by locals are often deeply rooted in cultural understanding and aim to create change from within, which may be more sustainable and respectful than external condemnation.
Women within these societies might believe that an outsider’s perspective could lack cultural sensitivity and ignore the nuanced dynamics at play, such as the pressure from a larger network of relatives, and might inadvertently reinforce stereotypes or create resistance to change.
Furthermore, these African women might desire to frame the initiative in terms of personal empowerment and community development rather than outright victimization, which can sometimes be implied by external actors. The concept of cultural relativism, the idea that a person's beliefs and activities should be understood based on their own culture, plays a significant role in how FGC is perceived and addressed.
Local advocates may also focus on community concerns regarding the upbringing and education of children, highlighting the importance of cultural transmission while promoting the abandonment of harmful practices.

An individual goes to a casino two weekends every year. While there, he usually loses several thousand dollars gambling. In between casino visits, he neither gambles nor thinks much about gambling. The MOST accurate assessment of this behavior would be:
a. This behavior is not a gambling disorder.
b. This behavior may not be a gambling disorder because the person doesn't gamble often enough.
c. This behavior may not be a gambling disorder because the person doesn't lose enough money.
d. This behavior is a gambling disorder.
Answer:
a. This behavior is not a gambling disorder
Explanation:
Because, to be a disorder it needs to interfere with the every day life. This is, relationships, work, family and even health. In this scenario the individual seems no to be addicted to gambling.
Given the DSM-5 criteria for a gambling disorder, which includes more than frequency and amount gambled, the individual in question may not have a gambling disorder. He only gambles a few times a year and doesn't exhibit other significant signs of gambling disorder such as lack of control, increased need to gamble, using it as an escape, or jeopardizing personal or professional life.
Explanation:The assessment of an individual's behavior as a gambling disorder is based on specific criteria rather than just frequency or amount of money lost. According to the DSM-5, a gambling disorder is characterized by a persistent and recurrent problematic gambling behavior, leading to clinically significant impairment or distress.
It involves four or more of the following recognized symptoms within a year: being preoccupied with gambling, needing to gamble with increasing amounts of money to achieve the desired excitement, repeated unsuccessful efforts to control or stop gambling, feeling restless or irritable when attempting to cut down or stop gambling, gambling as a way of escaping from problems, chasing losses, lying to conceal the extent of involvement with gambling, jeopardizing or losing a significant relationship, job, or educational or career opportunity because of gambling and relying on others to provide money to relieve desperate financial situations caused by gambling.
In this case, even though the individual gambles and loses a significant amount of money, he does not exhibit any of the other criteria known to characterize a gambling disorder. He doesn't seem to be preoccupied with gambling, doesn't show an increased need to gamble or a lack of control, doesn't seems to use it as an escape, nor does it appears to have jeopardized his personal or professional life. Hence, we might infer that this behavior may not be a gambling disorder because the person doesn't match enough of the significant symptoms associated with a gambling disorder.

Professor Newton gave a midterm exam where the scores ranged from 28% to 89%; the average score for the exam was 69%. Based on the phenomenon known as regression toward the mean, you should expect that
a. almost all students will score lower on the final than they did on the midterm.
b. almost all students will score higher on the final than they did on the midterm.
c. the students who scored near the average on the midterm will score lower on the final.
d. the students who earned the highest scores on the midterm will not do as well on the final.
Answer:
D
Explanation:
Based on the phenomenon known as regression toward the mean, you should expect that
the students who earned the highest scores on the midterm will not do as well on the final.
Final answer:
The answer is d. students with the highest midterm scores will likely score closer to the average on the final due to regression toward the mean.
Explanation:
The phenomenon of regression toward the mean suggests that if a student scored extremely high or low on a midterm exam, their score on the final exam will likely be closer to the average. For the students who scored near the average on the midterm, their final scores are likely to be around the same range, barring any changes in their preparation or the difficulty of the final exam. Hence, the correct answer to the question is:
d. the students who earned the highest scores on the midterm will not do as well on the final.
This happens because the exceptionally high scores are often partly due to factors that may not be replicated, such as luck or the particular compatibility of the midterm with the student's strengths, and so on a subsequent exam, their scores tend to fall back towards the average.
If a psychologist interested in the relation between number of years working for a particular company and loneliness at work surveyed 40 workers at this company and figured a correlation between these two variables of –.90, the correlation is considered aa. strong negative linear correlation
b. strong positive linear correlation
c. weak positive linear correlation
d. weak negative linear correlation
Answer:
strong negative linear correlation
Explanation:
Correlation coefficient is used in statistics to describe a relationship between two variables. A negative correlation describes the extent to which two variables move in opposite directions i.e. an increase in a variable is associated with a decrease in the other variable.
Correlation coefficient is between -1 and 1.
-1 shows a perfect, linear negative correlation, and 1 shows a perfect, linear positive correlation.
In this example, -90 shows a strong negative correlation.
The correlation of –.90 between the number of years working and loneliness at work represents a strong negative linear correlation. This high absolute value indicates a strong, consistent inverse relationship between the two variables.
Explanation:If a psychologist finds a correlation coefficient (r) of –.90 between the number of years working for a particular company and loneliness at work, this indicates a strong negative linear correlation. The sign of the coefficient (–) suggests a negative linear relationship, meaning that as the number of years increases, the level of loneliness at work tends to decrease. The value of the coefficient (0.90) is close to the extreme possible value of 1.0, which denotes a strong relationship.
The closer the correlation coefficient is to -1.0 or +1.0, the stronger the correlation, regardless of whether the sign is negative or positive. A negative correlation indicates that as one variable increases, the other variable tends to decrease. With an r-value of –.90, this correlation is amongst the stronger ones, suggesting that the variables have a very consistent inverse relationship with one another.
A solution contains an unknown mass of dissolved silver ions. When potassium chloride is added to the solution, a white precipitate forms. The precipitate is filtered and dried and then found to have a mass of 245 mg. What mass of silver was in the original solution? (Assume that all of the silver was precipitated out of solution by the reaction.)
Answer:
Mass of silver in the original solution = 0.1845 g
Explanation:
The precipitate must be of silver chloride. So,
Given that:
Mass of silver chloride = 245 mg = 0.245 g ( 1 mg = 0.001 g )
Molar mass of silver chloride = 143.32 g/mol
The formula for the calculation of moles is shown below:
[tex]moles = \frac{Mass\ taken}{Molar\ mass}[/tex]
Thus,
[tex]Moles= \frac{0.245\ g}{143.32\ g/mol}[/tex]
[tex]Moles= 0.00171\ mol[/tex]
From the reaction,
[tex]KCl+Ag^+\rightarrow AgCl+K^+[/tex]
1 mole of AgCl is formed from 1 mole of silver
So,
0.00171 mole of AgCl is formed from 0.00171 mole of silver
Moles of silver = 0.00171 moles
Molar mass of silver = 107.8682 g/mol
Mass = Moles*Molar mass = 0.00171 moles*107.8682 g/mol = 0.1845 g
Mass of silver in the original solution = 0.1845 g
The mass of silver in the original solution = 0.1845 g
Calculations and Parameters:We assume that the precipitate must be of silver chloride.
So,
Given that:
Mass of silver chloride = 245 mg = 0.245 g ( 1 mg = 0.001 g )Molar mass of silver chloride = 143.32 g/molThe formula for the calculation of moles is shown below:
Moles= Mass taken/Molar mass
Putting the values in:
Moles= 0.00171mol.
Given the reaction,
KCl + Ag^+ ----->AgCl + K^+
1 mole of AgCl is formed from 1 mole of silver
0.00171 mole of AgCl is formed from 0.00171 mole of silver
Moles of silver = 0.00171 molesMolar mass of silver = 107.8682 g/molMass = Moles*Molar mass
= 0.00171 moles*107.8682 g/mol
= 0.1845 g
