Two main assumptions of functional theory and conflict theory are Social stability, social integration and social class and gender.

What are the major assumptions of functional and conflict theories?

Functionalism: Social stability is key to have a strong society, and adequate socialization and social integration are necessary to achieve social stability.Conflict theory: Society is full of pervasive inequality based on social class, gender, and other factors.

Explain why a substantive disagreement may never be resolved. Your answer should be between 50 and 100 words.

Answers

Substantive disagreement may never be resolved because it leads to clashes of opinions.

A disagreement or argument is said to be substantial if it centers on the presentation of divergent viewpoints regarding the truth or the adherence to opposing ideals.

There must be a means to distinguish substantive disagreement (SD) from conceptual disagreement if legal concepts can be the subject of SD. Arguments that persons debating a certain philosophical problem are only having a linguistic argument are one approach to reject the substantiveness of the issue.

Explanation:

A case study in this chapter discusses the federal minimum-wage law. a. Suppose the minimum wage is above the equilibrium wage in the market for unskilled labor. Using a supply-and-demand diagram of the market for unskilled labor, show the market wage, the number of workers who are employed, and the number of workers who are unemployed. Also show the total wage payments to unskilled workers. b. Now suppose the secretary of labor proposes an increase in the minimum wage. What effect would this increase have on employment? Does the change in employment depend on the elasticity of demand, the elasticity of supply, both elasticities, or neither? c. What effect would this increase in the minimum wage have on unemployment? Does the change in unemployment depend on the elasticity of demand, the elasticity of supply, both elasticities, or neither? d. If the demand for unskilled labor were inelastic, would the proposed increase in the minimum wage raise or lower total wage payments to unskilled workers? Would your answer change if the demand for unskilled labor were elastic?

Answers

Now suppose the secretary of labor proposes an increase in the minimum wage, this would result in a downward spiral of employment rates. The logic is simple, employers always want to keep profit optimal. To do that, they need to keep costs at the lowest place possible. Hence, if they have to pay more for existing staff, hiring more is not exactly rational - all thing being equal.

What effect would this increase in the minimum wage have on unemployment?

As already indicated above, this would most likely keep unemployment rates in the same place or on the increase. To meet up with the government's requirements, some companies might have to lay-off.

If the demand for unskilled labor were inelastic, would the proposed increase in the minimum wage raise or lower total wage payments to unskilled workers?

Inelasticity means that the employers cannot do without unskilled labor. Thus, their  demand for same will remain constant regardless of the increase in minimum wages.

The sociological term that best describes the onlooker's behavior in this situation is that they are bystanders.

Who are bystanders?

A bystander is a person who observes or is aware of bullying occurring to another person. However, that does not imply they have to stand by and observe. Whether they realize it or not, spectators who do nothing encourage bullying behavior.

Someone who is being bullied will benefit from the words and/or acts of a helpful bystander. Bullying is more likely to end and the victim of bullying is more likely to recover if bystanders feel confident enough to take safe and effective action to support victims.

Bystanders may fail to recognize the scenario as an emergency and, as a result, act as if nothing is wrong when others behave calmly in the presence of a potential emergency because they are unsure of what the incident entails.
