An officer at Air Force Space Command noticed that operators that were fatigued did not seem to perform as well as those operators that were well rested. He was interested if this observation was statistically significant and if added automation could help mitigate any negative effects of fatigue on monitoring and controlling satellites. He designed a study to look into this question. He recruited volunteers willing to participate in a sleep study. Participants would initially be restricted in sleep for a few nights, then would come in and perform tasks in a simulator that were representative of operational tasks. Participants would then be required to sleep 8 hours a night for a few nights, then would come in and perform the tasks in the simulator again. A sub-set of the simulator tasks were at a low level of automation and the remaining simulator tasks were at a high level of automation.a)[4 pts] What is/are the study independent variable(s)

Answers

Answer 1

Answer:

The independent variables are the level of tiredness and the number of hours slept by the volunteers.

Explanation:

Independent variables are those that act on the dependent variables influencing a result, which can be observed by the researcher. In summary, the independent variable is one that can influence. In the case of the question above, we can see that the number of hours slept by the volunteers influenced the level of tiredness of the volunteers. These two variables were able to influence the level of proactivity and performance of the volunteers in their activities, which allows us to determine that these two variables are the independent variables of the study.

What Constitutional provision allows Congress to create special courts?

A. Article II, Clause 4
B. Article 1, Section 8, Clause 9
C. Article IV, Section 5, Clause 3

Answers

Answer:

Explanation:

I don't know what Answer A really is. Usually there is a numbered section preceding the clause. The clause does not stand by itself -- or nothing I've seen does that.

Article 4 section 5 clause 3: This part of the constitution tells how the constitution may be amended. To amend or change anything about the constitution requires a procedure. This then is the procedure.

I think the answer you want is B. The wording is "To Constitute Tribunals inferior to the the Supreme Court." This whole section 8 Article I has to do with the powers given to congress. Clause 9 is just one of these powers.

According to the attribution theory of leadership, leadership is characterized by ________. A. the impact of substitutes and neutralizers in enhancing the role of the leader B. the division of the group into ingroup and out-group members based on the leader's preference C. the focus on the actual accomplishments and performance of the leader D. the significant gains made in the mentoring relationship between the leader and follower E. the act of people ascribing qualities like intelligence or charisma to leaders

Answers

Answer:

E

Explanation:

E) The attribution theory of leadership says leadership is merely an attribution people make about other individuals. Thus we attribute to leaders intelligence, outgoing personality, strong verbal skills, aggressiveness, understanding, and industriousness. At the organizational level, we tend to see leaders, rightly or wrongly, as responsible for extremely negative or extremely positive performance.

According to the attribution theory of leadership, it should be noted that leadership is characterized by the act whereby people ascribe qualities such as intelligence or charisma to leaders.

The attribution theory explains how people explain why certain things happen.

The attribution theory of leadership explains that inferences are made about the ability of a leader by looking at the behavioral and the environmental cues of the leader and interpreting them.

In conclusion, the correct option is E.

Answers

Answer:

The last two years of the war from July of 1951 until July of 1952 mostly involved trying to:

b. enter into a truce.

Explanation:

This question refers to the Korean War, which began on June 25, 1950, when North Korea invaded South Korea. Several countries ended up involved in it, including the United States and China. In total, the war lasted three years.

During the last two years, the effort from the countries involved was to achieve a truce. At no point the unification of the countries was a possibility. If it happened, it would represent a loss to either the capitalist or the communist side of the world, so to speak. As a matter of fact, truce was indeed achieved, and the border between the two countries remained practically the same it was before the war began. At the border, there is a demilitarized zone.

Explanation:

in what ways are illegal immigrants important/ helpful to the U.S.​

Answers

Illegal immigrants provide a cheaper alternative and extra labor to the US work force, however, that is not exactly a "positive benefit".

The only helpful benefit that brings is to a private or commercial company, which allows them to not only skirt around having to pay extra for employee security, but also their benefits.

There are many more cons to illegal immigrants coming in to the US. Most of them are denied because of criminal history or illegal possessions, which, if allowed across the border can be detrimental to the societal structures of the US. Another con can be that they would take over jobs that are typically held by US citizens, prompting the US government to have to work harder in providing services to help prop up US families to survive, which in turn drives up the taxes. Still another can be the misuse of support and rights given to legal immigrants and citizens, including the usage of US benefit programs, the usage of their information in a illegal manner, such as use in ballots, and many others.

Illegal immigration takes away from the US citizens, and should be harshly dealt with. There are channels in which one can legally immigrant into the US, as well as channels for refugees in which one can take if the immigration process takes too long. However, illegal crossing the border is a crime, and should be dealt with like all other crimes. There are not much benefits in which a illegal immigrant can bring compared to the likely detriments that would most likely occur.

The distance from Earth to Mars is about 54,600,000 km. How many light-years is this?

Answers

Answer:

Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes.

Explanation:

  km               light years

54,600,000 5.7712 x 10-6

54,700,000 5.7818 x 10-6

54,800,000 5.7924 x 10-6

54,900,000 5.8029 x 10-6

So 54,600,000 km is equal to 5.7712245538e-6 light years.

Mars is roughly 54,600,000 kilometers away from Earth. The speed of light is roughly 186,282 miles per second (299,792 km per second). The time it would take for a light to travel from Mars to Earth (or the other way around) is as follows: 182 seconds, or 3.03 minutes, would be the closest approach.

What do you know about light-years?

A light-year, also spelled light year, is a significant measure of length used to express astronomical distances. It is about comparable to 5.88 trillion miles (5.881012 mi) or 9.46 trillion kilometers (9.461012 km). A light-year is the distance that light travels in a vacuum in one Julian year, according to the International Astronomical Union (IAU) (365.25 days).

The name "light-year" is occasionally misunderstood as a unit of time since it contains the time measurement word "year".
