Answer:
The answer is "option A"
Explanation:
According to the United Nations report the Drugs and Crime Prevention statistics, 78.7% of homicides victims were men, which were more likely killed in 193 of the 202 countries or regions listed. In this 16% of the children are more likely to be murdered away from school than at school, that's why except choice "a" all are incorrect.
Answer:
Variable Ratio Schedule
Explanation:
First, there are two different types of reinforcement:
The positive reinforcement applies a stimulus to increase the frequency of the desirable variable.
The negative reinforcement removes a stimulus to increase the frequency of the desirable variable.
However, the positive reinforcement divides itself in different types:
A continuous reinforcement schedule gives us a reinforcement every time we engaged in the desired conduct.
On the other side, the partial reinforcement schedule also divides itself in
And these divide themselves in fixed or variable.
- The fixed ratio schedule gives a reinforcement after a <u>fixed number</u> of desired responses.
- The variable ratio schedule gives a reinforcement after a <u>changing</u> <u>number</u> of desired responses.
- The fixed interval schedule gives a reinforcement after a <u>constant amount of time.</u>
- The variable interval schedule gives a reinforcement after a <u>variable amount of time.</u>
In the example, the rats get a pellet of food, so we're talking about a reinforcement. They <u>don't get a reward EVERY TIME</u> they press the bar so we are not talking about a continuous reinforcement but a partial reinforcement. Since the rats press the bar and get a reward after certain <u>NUMBER</u> of times, we're talking about a ratio schedule. Finally, the number of times they need to press the bar to get a reward <u>VARIES</u> from trial to trial so this is a Variable Ratio Schedule.
Unauthorized disclosure of Confidential information could be expected to jeopardise national security. Unauthorized disclosure of Secret information could have serious consequences for national security.
Tests for confidentiality determine whether unauthorised disclosure is possible. When performing confidentiality tests, you are attempting to determine whether data is being disclosed to people for whom it was not intended.

on July 26, 1948, he issued an executive order abolishing segregation in the armed forces and ordering full integration of all the services. Executive Order 9981 stated that “there shall be equality of treatment and opportunity for all persons in the armed forces without regard to race, color, religion, or national origin.” The order also established an advisory committee to examine the rules, practices, and procedures of the armed services and recommend ways to make desegregation a reality. There was considerable resistance to the executive order from the military, but by the end of the Korean conflict, almost all the military was integrated.
