Answer:

Option D) is correct

Explanation:

Dr. DeVries is interested in measuring how practice in problem solving affects this ability. The population of interest is high school seniors. However, the sample consists of students who attend an exclusive college preparatory school out of which half of the sample receives practice in solving particular types of problems, while the other half does not receives practice in solving those types of problems. Now groups take the same problem-solving test. But  DeVries may not be able to generalize his findings as the sample is not representative of the population.

Addressing public policies are an important job of citizen and members of government in any society. What are the three stages o
MAXImum [283]

Answer:

The three stages of Public policies are

  • Agenda setting
  • Policy Formulation
  • Adoption
  • Implementation
  • Evaluation

Explanation:

Howlett and Ramesh’s model identifies five stages: agenda setting, policy

formulation, adoption (or decision making), implementation and evaluation. Let us briefly examine each of these stages.

AGENDA SETTING

This stage refers to the process through which a policy and the problem it is intended to address are acknowledged to be of public interest. Some

authors differentiate among several types of agendas, including discussion agendas and decision agendas.

POLICY FORMULATION

At this stage, the public administration concerned examines the various policy options it considers to be possible solutions. It should be noted that

coalitions of actors strive, through the use of advocacy strategies, to gain priority for one specific interpretation of both the problem and its solution. It

is at this stage that power relationships crystallize, determining the direction a policy will take.

ADOPTION

Adoption is the stage during which decisions are made at the governmental level, resulting in a decision that favours one or more approaches to addressing a given problem.

IMPLEMENTATION

At this stage, the policy’s implementation parameters are established, which can directly affect the eventual outcome of the policy. Several factors combine to determine the actual effects of a policy and how well it achieves its objectives. Factors noted by Sabatier and Mazmanian include:

  • The type and complexity of the problem addressed;
  • The magnitude of the expected change and the groups targeted by the policy;
  • The human and financial resources devoted to implementation, and;
  • The administrative structures and regulations that will be put in place to support implementation of the policy (Sabatier & Mazmanian, 1995).

EVALUATION

This is the stage during which a policy is evaluated, to verify whether its implementation and its effects are aligned with the objectives that were explicitly or implicitly set out. This evaluation can be carried out by the government apparatus, by consultants or by civil society (Howlett & Ramesh, 2003).
