4. How might these questions about human nature, purpose, and flourishing be answered by those holding a pantheistic or atheistic (choose one) worldview

Answers

Answer:

The answer is below

Explanation:

Using Atheistic worldview.

It is generally believed that, atheist do things or acts based on logical conclusion, rather than following the laid down rules or mode of living set out by God  and prophets.

Thus, atheist would view human nature, purpose, and flourishing based on their own experience or conscious self reasoning, instead of seeking God for answers on those questions, by looking for meanings through scriptures or word of God.

To the athiest, human nature will be a composition of his biological instincts and physical experience. The question of purpose to athiest will be based on self definitions, rather than central purpose or destiny, and question of flourishing will also be based on personal evaluation in comparison to his immediate or socio-enviroment.

Modernity has largely led to the collapse of strong marital ties and subsequently affected the choice of mates. Critically provide a four (4)- point coherent and logical underpinnings to prove the truth or otherwise of this statement

Answers

Answer is given below

Explanation:

Different people define it in different ways. Sociologists cannot accept the same meaning. For our purposes, we have defined marriage as a legally recognized social contract between two persons, which is traditionally based on sexual intercourse and affects the permanence of the union. In formulating a comprehensive definition, we must also consider variations such as whether a formal legal union is necessary (think of a common law marriage and its equivalents), or whether more than two people can participate. Other changes in the definition of marriage include whether spouses are of the opposite sex or of the same sex, and how one of the traditional expectations of marriage (having children) can be understood today. Based on Simel's distinction between social and contact forms and content (see Chapter 6), we can analyze the family as a social form that exists within five different materials or interests in sexual activity, economic cooperation, reproduction, child socialization, and emotion.As we expect from Simmel's analysis, some or all of these substances are expressed in a variety of family types: nuclear families, polygamous families, extended families, same-parent families, single-parent families, zero-child families, etc., however, coincidentally in the form of family adoption it will not be; Instead, these forms are determined by cultural traditions, social structures, economic pressures, and historical changes. They are subject to intense moral and political debate about the definition of family, "family decline" or policy options that best serve the well-being of children. In these discussions, sociology demonstrates its practical side as a discipline that can provide the real knowledge needed to make evidence-based decisions on political and moral issues related to the family.  Sociologists are interested in the relationship between the marriage organization and the family organization, because, historically, marriages form a family, and society-built families are the most basic social unit. Both marriage and family play an acceptable status role in society.

1)Predict: How will supply and demand and labor substitutes in these job markets affect their pay and likeliness to get a job?

2)How will supply and demand within the job market affect my career choice?

Answers

Answer:

1)Predict: How will supply and demand and labor substitutes in these job markets affect their pay and likeliness to get a job?

Supply, demand and labor substitutes are three variables that will determine the wage.

For the medical field, the demand for doctors tends to be higher than the supply of doctors, because becoming a doctor is costly both in time and money. This means that doctors will be well-paid, according to this model.

Besides, there are not so many labor substitutes for a doctor, increasing the probability of a high pay for them.

The opposite occurs for barbers. Barbers are easier to supply, and demand is not as high for them. This means that a barber salary will be much lower than a doctor's salary. Finally, barbers do have more labor substitutes as well.

2)How will supply and demand within the job market affect my career choice?

Supply and demand within the job market, as explained above, largely determines the quality of the career that you choose. A labor market with high supply and low demand means that the chosen career will be paid less, while a labor market with low supply and high demand means that the chosen career will be paid high salaries.

Answer:

C. " ...That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it..."

Explanation:

The Social Contract Theory says that people choose to form political entities because they agree to be ruled by governments only when these goverments act for the common good. According to this theory, it is the right of the people to change the government in case of general disagreement with it.

This is one of the theories that justified the American Revolution, and the French Revolution, and the Haitian Revolution.

what identified the characteristics of the plains Indian's cultures.

Answers

Answer:

Explanation:

Every tribe was different, although certain elements were common to most of the Plains tribes. The true Plains peoples were entirely nomadic, following migrating herds of buffalo, antelope and deer that provided the major portion of the diet. They therefore needed mobile dwellings: the tipi-style lodges that had different names in each of the many Plains languages.

Each tribe was based on clans and small hunting bands; only very rarely would an entire tribe come together in one place - and this would only be for a very short time due to lack of sufficient food and grazing. Consequently most tribes had no head chief.

All plains people depended on horses for transport, hunting and warfare. Some war parties set out on foot, in the expectation of stealing enemy horses that could be ridden and herded back to camp.

Bows were the primary weapon for hunting and in war.

The Plains people generally lacked pottery since it was far too heavy and fragile for a nomadic lifestyle; instead containers of rawhide (parfleches) were made, which were very light and durable.

Hunting bands would not remain in any one place for more than a few weeks, except in winter when a sheltered valley would be used for many month

Answer:

Explanation:

Social information processing theory suggests that children with disruptive behavior problems perceive, interpret, and make decisions about social information in ways that increase their likelihood to engage in aggressive behaviors.

For example, if a child is pushed by another child in the lunch line, he/she may be more likely to assume the other child did it intentionally to hurt them, rather than assume that it was an accident.

A new resident recently fell and broke his hip, which is what prompted his move into the long-term care facility. He has become very dependent on other for the first time in his life. Even though the facility is comfortable, provides good medical care, and serves food he enjoys, he is depressed.
