Social Studies

hram777 [196]1 year ago

According to the natural selection concept, lighter skin colour is developed to maximize vitamin D synthesis.

What is the connection between skin colour and vitamin D?

Compared to skin that is less pigmented, skin pigmentation, or melanin, absorbs the UVR that starts vitamin D synthesis, lowering the amount of vitamin D produced for a given exposure.

Why does lighter skin produce more vitamin D?

UV rays can be absorbed more effectively by lighter skin. This aids the body's ability to manufacture more vitamin D for functions like calcium development. People with a fair complexion who live in areas with lots of sunlight and close to the equator are more likely to experience folate deficiency.

Ok I need one paragraph for each and I need examples from the civil rights movement for each one listed below. Structural Condit
alexandr402 [8]

Structural conditions refer to the conditions of buildings in neighborhoods. Certain neighborhoods have better structural conditions than others and this affects prices of rent and generally the type of population occupying the area. There are certain neighborhoods where an apartment for rent are very cheap and people of a lower socioeconomic status generally live in the area. The structural conditions of these apartments are generally not as well kept and they have lower structural conditions. An example from the civil rights movement would be the fact that "black" neighborhoods had poor structural conditions and African American people were not allowed to occupy the houses with better structural conditions in predominantly "white" neighborhoods.  

Structural strains refer to the stereotypes that one person may perceive certain things about their culture. This affects how they act and how they look at others around them. It can be a predictor on likelihood of committing a crime because the person may feel like that is what expected of them so they might as well do it. The person feels limited to what they know or have grown up with so they have trouble breaking stereotypical barriers placed on them early in life. An example of this in civil rights movement is how the children had to go to schools that had people only of their race. The opportunities at certain schools were limited solely based on race.

Generalized beliefs continues what I was talking about with structural strains. Generalized beliefs are beliefs that are expected or beliefs that the majority of a population has. This can affect people because certain groups of people are viewed better than others.

Precipitating factors are factors that trigger a behavioral response. This word can be used for many different circumstances. It can be used in regards to an illness or an accident. In civil rights time precipitating factors would be protests in response to the civil rights movement. It could also be a protest in response to how African Americans were being treated at the time.

Mobilization is the government making moves to gather the military and prepare them for a certain movement. During the civil rights movement an example of mobilization is when the National Guard was called in to help students as they started to attend schools that were predominantly white. They were called to make sure the peace was kept during this time.

Social control is the conformity of society to follow social norms because of laws or social pressure. During the civil rights movement children that went to school with their own race grew up with this being the norm. They were conforming because of the social pressure from family and friends. Once laws started changing, the law attempted to move social norms to integrate and the citizens were required to abide by the new laws. The laws regarding integrating schools were being enforced by the National Guard which is also an example of social control.

What is social inequality?
Grace [21]
The ~unequal~ statuses of different individuals in a society. for example, a doctor has a higher social status than a janitor working at the same hospital. the doctor might be awarded for his work, while the janitor is mostly ignored. the doctor may also have come from a fairly wealthy family and received a good education, while the janitor may have had economic disadvantages and a poor quality education. so the doctor and the janitor are socially unequal. social inequality is very closely connected to economic inequality, so if you ever see the phrase "socio-economic inequality," that's why.

According to Papadakis et al. the risk of being disciplined by a state board increased with length of time since graduation, and
Lelechka [254]

All University of California, San Francisco School of Medicine graduates who received disciplinary action from the California Medical Board between 1990 and 2000 were the subject of a case-control study.

By medical school graduating year and preferred specialty, control graduates were matched.

The National Board of Medical Examiner scores, the male gender, undergraduate grade point average, MCAT scores, medical school grades, and negative excerpts describing unprofessional behavior from course evaluation forms, dean's letters of recommendation for residencies, and administrative correspondence were the predictor variables.

The severity of unfavorable extracts was graded (Good/Trace versus Concern/Problem/Extreme). The outcome factor was disciplinary action taken by the state board.
