Explain why driving a gasoline-powered car contributes to global warming, making sure to include the concept of "greenhouse gas".
Gasoline-powered cars emit carbon-dioxide from their tailpipes as a result of the burning of gasoline in the car engine, which produces the power to move the car. Carbon-dioxide leaving the tailpipe of a car enters the earth's atmosphere and acts as a greenhouse gas. Greenhouse gases in the earth's atmosphere absorb heat from the sun, both directly and from sunlight bouncing off the earth heading back into space. We need at least some greenhouse gases in order to keep our Earth warm - but the increase in carbon dioxide emissions from gasoline-powered cars over the last century has significantly contributed to an increase in the amount of greenhouse gases in the earth's atmosphere, leading to a measurable increase in average earth's atmospheric temperatures (e.g. "global warming").
The Stanford Prison Experiment was considered to be an experimental test of the power of "structure" versus "agency" in social outcomes. How did the results demonstrate the power of "structure"? How might the results have been different if "agency" had played a larger role in the outcome of the experiment?
In the Stanford Prison Experiment, test subjects who were considered socially and psychologically "normal" ended up making behavioral choices (such as choosing to physically and psychologically abuse other test subjects and/or allowing themselves and others to be physically and psychologically abused) that seemed abnormal and immoral. The experiment is usually interpreted to be a demonstration of the power of "structure" in which the social conditions artificially created in the experiment (prison setting; abusive peers; authority figures condoning abuse) greatly influenced the behaviors of the test subjects. If "agency" had played a larger role, it is expected that test subjects would have had a lower incidence of performing and allowing abusive behaviors since their personal values, pre-established before the experiment, would have led to greater resistance to such behaviors.
Provide one example in which a kinesic communication signal means one thing in one culture but means something entirely different (or nothing at all) in another culture.
The Indian "side-nod" is an example of kinesic communication; the head movement from side to side can indicate doubt, approval, or excitement depending on the speed of the nod and contributing kinesic signals such as eyebrow movement. This side-nod has no meaning in U.S. culture -- a person using this form of communication in an exchange with an individual born and raised with U.S. cultural standards would not likely pass any meaningful information to that individual (unless that individual was familiar with Indian cultural gestures!)
