In a study of the results of a diabetes teaching program conducted at a senior center, the blood glucose levels are taken by volunteers using their own personal equipment and were compared before and after the program. What potential threat to internal validity is demonstrated in this study

Answers

Answer 1

Answer:

Instrumentation validity

Explanation:

The potential threat that exists in this scenario, is Instrumentation validity. This happens when different instruments are used to test the same thing. There exists the possibility that some of those instruments are not necessarily measuring what they are supposed to be measuring, correctly. This ultimately gives mixed results and can ruin a study. Which is what is happening in this scenario as all the volunteers are using their own "separate" personal equipment.

why do women suffer a double-standard in physical appearance?

Answers

Answer:

The belief that women and men are held to different standards of sexual conduct is pervasive in contemporary American society. According to the sexual double standard, boys and men are rewarded and praised for heterosexual sexual contacts, whereas girls and women are derogated and stigmatized for similar behaviors. Although widely held by the general public, research findings on the sexual double standard remain equivocal, with qualitative studies and early attitudinal surveys generally finding evidence of the double standard and more recent experimental vignette designs often failing to find similar results. In this study, we extend prior research by directly measuring the social status of sexually permissive youth. We use data collected from the National Longitudinal Study of Adolescent Health to relate adolescents’ self-reported numbers of sexual partners to a network measure of peer acceptance. Results suggest that the association between lifetime sexual partnerships and peer status varies significantly by gender, such that greater numbers of sexual partners are positively correlated with boys’ peer acceptance, but negatively correlated with girls’ peer acceptance. Moreover, the relationship between boys’ sexual behaviors and peer acceptance is moderated by socioeconomic origins; sexually permissive boys from disadvantaged backgrounds are predicted to have more friendships than permissive boys from more advantaged backgrounds. Our results thus support the existence of an adolescent sexual double standard and suggest that sexual norms vary by both gender and socioeconomic origins.

Read the passage.

The king adorns himself like a woman (wearing necklaces) round his neck and (bracelets) on his forearms, and he puts on a high cap decorated with gold and wrapped in a turban of fine cotton. He sits in audience or to hear grievances against officials in a domed pavilion around which stand ten horses covered with gold-embroidered materials. Behind the king stand ten pages holding shields and swords decorated with gold, and on his right are the sons of the (vassal) kings of his country wearing splendid garments and their hair plaited with gold.

Who is Mansa Musa?

Mansa Musa was the ninth Mansa of the Mali Empire, which reached its territorial peak during his reign. Musa is known for his wealth and generosity. He has been subject to popular claims that he is the wealthiest person in history, but his actual wealth is not known with any certainty. His riches came from the mining of significant gold and salt deposits in the Mali Empire, along with the slave and ivory trade.

At the time of Musa's ascension to the throne, Mali in large part consisted of the territory of the former Ghana Empire, which Mali had conquered. The Mali Empire consisted of land that is now part of Guinea, Senegal, Mauritania, The Gambia, and the modern state of Mali.

Musa went on hajj to Mecca in 1324, travelling with an enormous entourage and a vast supply of gold.

Why did the United States government increase its supply of nuclear weapons during the 1950s?

Answers

Answer:

To react to the impending crisis that was going on so in self defense they increased there arsenal.

Answer:

The US government's decision to develop a hydrogen bomb, first tested in 1952, committed the United States to an ever-escalating arms race with the Soviet Union. The arms race led many Americans to fear that nuclear war could happen at any time, and the US government urged citizens to prepare to survive an atomic bomb.

In 1950, the US National Security Council released NSC-68, a secret policy paper that called for quadrupling defense spending in order to meet the perceived Soviet threat. NSC-68 would define US defense strategy throughout the Cold War.

Answers

Answer :

The central idea focused on emphasizing on faith, the power of god's grace and centralizing the Bible.

Martin Luther and John Calvin were the greatest protestant reformers. : John Calvin and Martin Luther broke from the Catholic Church by seeing the corruption in it. Luther believed that the individual has control over what happens in his life. Calvin believes in the doctrine of predestination.

Poverty, resentment and social discontent if the mass were some of the reason for their success.
