If the wave theory of democracy is correct, then will the proportion of democratic countries increase or decline?

Answers

Answer:

The proportion will increase and decrease at times.

Explanation:

There have been 3 recognized waves of democracy, a term that was popularized by the political scientist Samuel P. Huntington in 1987.

With each wave, dozens of countries have democratized their governments, but this number usually goes down a few years later and falls to a flat line.

For instance, in 1982 the first wave took place when 29 new democracies were formed after the fall of the Ottoman, German and Russian empires. However, only 24 years later, the number of democracies in the world was just 12.

As can be seen, the wave of democracy has its ups and downs, and it doesn't follow a reliable, constant pattern.

One way to gain acceptance from the local population after making contact is to discuss the similarities between your religions. This helps to show you are peaceful and mean no harm.

A. True
B. False

Answers

Answer: false

Explanation:

A topic of individual religion is mostly likely to raise a conflict because each person believes differently and everyone thinks differently of their religion when compared to others. When you try to say there are similarities between your religion and that of others it may be offensive to the other person because they may not think the same when it comes to your religion , some researchers say religion is a private institution. Trying to involve it in your public communication or in a way to gain acceptance may backfire because you never know how others feel particularly about the values of your religion.

Final answer:

Discussing similarities between religions can help to create acceptance, but it is also crucial to understand and respect the local customs and traditions and appreciate the cultural diversity. The statement is therefore true.

Explanation:

The statement that discussing similarities between religions after making contact is a guaranteed way to gain acceptance from the local population and signal peaceful intentions is true.

While shared religious beliefs can create a sense of commonality and mutual respect, it's also essential to appreciate cultural diversity and always respect the local customs, traditions, and beliefs, whether religious or otherwise.

Darrin is a good piano player. When he is alone and bored his arousal is low and he often gets distracted and makes mistakes. When he is in a recital with strangers, he sometimes gets too nervous and aroused and also makes mistakes. His best performances are typically at home when family and friends are nearby, and his arousal level is moderate. The variations in Darrin's performance can be best explained by the _____.

Answers

Answer:

Yerkes-Dodson law

Explanation:

The Yerkes-Dodson principle is a hypothesis on arousal and performance that worries what often psychologists seek to identify as the "best conditions for doing something".

In social psychology, research will see often the influence of social factors that put pressure on an individual which tend to make his performance better.

However with Yerkes-Dodson law, physiological or mental arousal only goes on to a certain point, and if too much pressure is exerted a decrease in performance occurs.

The performance and arousal are directly related, so finding an n optimum level of positive pressure will help, whereas little or no pressure can mean often a lower performance.

When playing the piano, he may experience a higher degree of energy release.

Darrin will play better when he feels family and friends nearby thereby confirming this notion.

A word element at the end of the roots that changes or adds to its meaning is a(n)

Answers

A word element at the end of the root that changes or adds to its meaning is a suffix.

Like prefixes, suffixes are a type of affix. This means that when added to a word base, they create a derivative or inflectional form of this word, with a new meaning.

For example,

adding the suffix -ly to an adjective makes it an adverb (commercial - commercially);adding the suffixes -able or -ible to a verb makes it an adjective which means "fit or liable to be ..." (break - breakable)
Final answer:

A suffix is a word element at the end of the root word that changes or adds to its meaning. They are morphemes and used to form new words and convey different meanings.

Explanation:

A word element at the end of the root word that changes or adds to its meaning is an suffix. Suffixes are morphemes, which are the smallest meaningful units in a language. These suffixes are very commonly used in English to form new words and convey different grammatical meanings. For instance, in the word 'importance', the '-ance' is a suffix that changes the verb 'import' to a noun 'importance'. Therefore, to understand the meaning of a complex word, it is often helpful to look at its root, and any prefixes or suffixes it might have.
