In recent discussions of climate change, a controversial issue has been whether it is caused by human activities or is a result of natural patterns. From one perspective, scientists point to evidence that links human activities, such as burning fossil fuels and deforestation, to global warming and climate change.
How to fill in the blanks ?On the other hand, however, some argue that the climate has always been subject to change and what we are seeing is a natural fluctuation.
Every individual has a role to play. Every individual makes a difference." According to this view, the actions and choices of each person contribute significantly to the overall health of our planet.
In sum, then, the issue is whether climate change is anthropogenic or a natural cycle. My own view is that while there may be natural elements to climate change, the overwhelming consensus in the scientific community is that current patterns are largely due to human actions.
Though I concede that the Earth's climate has undergone changes over millennia without human influence, I still maintain that the rapid changes we are witnessing are not part of a natural cycle. For example, the unprecedented rate of carbon dioxide emissions correlates strongly with industrial activities.
Although some might object that economic development should not be hampered by environmental concerns, I would reply that sustainable development is crucial for long-term economic health. The issue is important because the well-being of future generations depends on the decisions we make about the environment today.

Can you conclude that people become more politically conservative as they get older? Why or why not? c. Propose alternative ways of studying this topic.
Answer:
The study was conducted in a cross-sectional analysis.No, it can't be concluded that people become more conservative with age.Longitudinal analysis can be an alternative way.Explanation:
Cross-sectional analysis is a research methodology that studies a group of people from different demo-graphical backgrounds at a same period of time.
No, it can't be concluded that people become more politically conservative as they get older because we should consider other factors that contributes to their ideologies and upbringings. Perhaps other independent variable such as time, education, society, multi-culturism, etc may play a vital role in determining whether individuals are politically liberal or conservative.
To determine political identity of different age groups, longitudinal analysis can be an alternative way. Longitudinal analysis is the process of studying a group of people over a long period of time. Though this process may be time consuming, it may help in determining how people tend or do not tent to change their behaviors with time and age.

Your friend Dave says: "How can you stand to study the history of psychology? Every single one of those theories is basically the same: the brain controls our behavior." Given the history of psychology, evaluate Dave's claim using the following terms in their appropriate context:•Introspection•Psychoanalytic theory•Behaviorism•Humanistic psychology•Cognitive revolution•Cognitive dissonance •Conformity•Social-cultural perspective
ANSWER:
For Dave to see all the theories in phycology to be the same, it means Dave is one sided in his understanding of those theories, because all those theories is all about the human mind and how it relates to it's internal and external environment.
If we should INTROSPECT Dave using PSYCHOANALYSIS, we will see that his BEHAVIOR was acquired by the way he has conditioned his mindset. To help Dave in his COGNITIVE REVOLUTION, We can only apply HUMANISTIC PSYCHOLOGY which will help him understand his COGNITIVE DISSONANCE, as he needs CONFORMITY in his SOCIAL-CULTURAL PERSPECTIVE.

Ring of Fire DEFINITION
The Ring of Fire, also known as the Circum-Pacific belt, is a horseshoe-shaped zone of intense geologic activity that encircles the Pacific Ocean. It's aptly named due to its concentration of volcanoes and frequent earthquakes, making it seem like a fiery ring around the Pacific basin.
Here are some key facts about the Ring of Fire:
Length: Approximately 40,000 kilometers (25,000 miles) long, stretching from the Andes Mountains in South America to New Zealand and Indonesia.
Activity: Houses around 75% of the world's active volcanoes and is responsible for 90% of the world's earthquakes, including many of the most powerful ones.
Formation: Caused by the movement of tectonic plates, mainly the subduction of oceanic plates beneath continental plates or other oceanic plates. This collision creates friction and melts rock, leading to volcanic eruptions and earthquakes.
Features: The Ring of Fire encompasses island arcs, mountain ranges, deep ocean trenches, and continental margins.
Impact: While posing risks like volcanic eruptions and earthquakes, the Ring of Fire also brings fertile land, geothermal energy resources, and diverse ecosystems.

Explanation:
Read the excerpt from act 1 of The Monsters Are Due on Maple Street.
DON
And he never did come out to look at that thing that flew overhead. He wasn't even interested.
(he turns to the faces in the group, his face taut and serious)
Why? Why didn't he come out with the rest of us to look?
CHARLIE
He always was an odd ball. Him and his whole family. Real odd ball.
Which element of drama is highlighted in the stage direction?
"The element of drama highlighted in the stage direction is foreshadowing.
In the given excerpt from The Monsters Are Due on Maple Street, the character Don points out that a neighbor did not come out to look at the mysterious object that flew overhead, which is unusual behavior given the context of the situation.
The stage direction he turns to the faces in the group, his face taut and serious suggests that Don is concerned or suspicious about the neighbor's absence, which may hint at future conflict or revelation regarding this character's behavior.
Foreshadowing is a literary device used to give an advance hint of what is to come later in the story. In this case, the neighbor's lack of interest in the flying object and the subsequent suspicion it arouses in the other characters foreshadow the breakdown of trust and the ensuing paranoia that will unfold among the residents of Maple Street as the play progresses.
It sets the stage for the exploration of themes such as fear of the unknown, mass hysteria, and the fragility of social order when faced with an external threat."

d. the scientific basis of his theory that allowed predictions of future behavior.
Explanation:
Freud as a renowed neurologist and who is perhaps most known as the founder of psychoanalysis was a great social scientist over the past few decades.
His study on emotional disorder known as hysteria helped him to discover the relationship between the symptoms and the traumatic experience which the patient passes through.
This observation had lead him to a major contibution in the scientific community with his theory used to predict future behaviour to be exhibited by an individual.

those with authoritarian personality believes in the use of force or harsh means to ensure that people succumb to what he or she require of them. most times, the people with this kind of personalities hardly trust or believe in others. they see negativity in others.
Answer: Authoritarianism
Explanation: The cousins differ in their authoritarianism. Authoritarianism is defined as the belief that power and status differences should exist within an organization (in this case the family). It places high value on toughness and low value on subjective feelings, holding conventional values, and judging others strictly.

A difference of opinion among the cousins concerning whether power and status differences should exist within the family is a difference in authoritarianism.
In a population entirely composed of solitary prey, the fitness payoff to individuals is P. But then mutant individuals arise that use others as living shields. When a solitary individual is found and used by a social type for protection, the solitary animal loses some fitness (B) to the social type. The costs (C) to social individuals include time spent searching for another individual to hide behind. We will assume that when two social individuals meet, each has an equal (1/2) chance of being the one to hind behind the other when a predator attacks.
Explanation:
Initial fitness is P. Now after the solitary individual being used is social mutant, then the solitary animal drops fitness by B
In such case, the net fitness of Solitary would be ;
P-B
Now the costs (C) for finding a new animal and training it;
P+B-C
Now when the two social types interact, they have a 1/2 chance of being behind the other when a predator attacks
Safest when solitary
P+B/2-B/2-C = P-C
Since P-C would be less than P so the initial condition was better than this one

For this paper, you will research the life and career of Milton Friedman providing an overview of his life and main economic theories paying particular close attention to the finer points of the Friedman doctrine. The paper should focus on these main ideas and use at least 3 outside resources: 1. What was Friedman's educational background
Answer:
Milton Friedman was an American economist who wrote fundamental works in the fields of macroeconomics, microeconomics, economic history and statistics. In 1976 he received the Alfred Nobel Memorial Award for Economics for his achievements in the field of analysis of consumption, history and the theory of money and for his demonstration of the complexity of the stability policy. Friedman is regarded alongside John Maynard Keynes as the most influential economist of the twentieth century.
Friedman, who considered himself a classic liberal, represented the Chicago School, and emphasized the advantages of a free market and the disadvantages of government intervention. His basic attitude is expressed in his bestseller Capitalism and Freedom (1962). In it he called for the minimization of the role of the state in order to promote political and social freedom. In his television series Free to Choose, Friedman explained the functions of the free market and emphasized in particular that other economic systems could not adequately solve a society's social and political problems.
