Deliverable Length: Minimum of 10 pages including the bibliography, APA format

Part 1: Topic Research and Selection

Begin this process by researching what health care organizations are doing or attempting to do to increase profitability. Remember, profitability can be improved from many different angles. A nonexclusive list of potential ways would be adding additional services, decreasing costs, increasing the amount of services that are provided, or implementing a quality improvement program that qualifies for incentive monies. Check trade journals or professional discussion boards, or reach out to existing health care managers.

Part 2: Literature Review

Perform a literature review of the solution that you have decided to apply to your organization. The review will encompass several articles, and at least 1 of the articles must be peer-reviewed. Look at current material (within the last 2 years). Remember, a literature review includes a summary of the information that you found that is relevant to your topic as well as an APA reference for each resource that you reviewed.

Identifying what topic to perform research on should be accomplished quickly because you will need sufficient time to perform your literature review. Review a minimum of 10 documents. The review should be between 10 pages, including the bibliography. Use APA format.

Application: Implementation of Crime Laws

The Matthew Shepard Act allows the federal government to assist states in prosecuting hate crimes. Many states have their own hate crime laws, but the Matthew Shepard Act allows the U.S. Department of Justice to provide funding to states for investigating or prosecuting hate crimes that result in death or bodily harm to targeted people. The federal government may also take the lead in this investigation or prosecution as necessary (Human Rights Campaign, 2009). Human rights advocates point out that one of the positive outcomes of the Matthew Shepard Act may be increased support for school programs for raising awareness and preventing hate crimes among juveniles (Dillman, 2009).

For this Assignment, select a law or policy inspired by a case involving victims described in the Interactive Community. You can use the law or policy you selected for the Discussion or you may choose a new one. Identify the jurisdiction where the law is implemented and consider the impact of the law on law enforcement, the courts, and the corrections system. 

The Assignment (2–3 pages):

• Visit the Interactive media below.
• Briefly describe the law or policy you selected.
• Explain whether the law or policy is implemented at the local, state, and/or federal level(s).
• Explain how the law or policy impacts law enforcement, the courts, and the corrections system.

Change is usually positive, but it can also be difficult to embrace at times.  Employees can be resistant to change, while managers may feel that it is necessary for organizational stability.  Discuss the challenge of change as it relates to health care organizations.  What is the overall impact of change on the organization, its employees, and its constituents, and what role does the manager play as an agent of change?  In addition to responding to these questions, review the examples of successful change in your textbook and choose two examples to discuss in greater detail.  What did you learn from these examples?  In each case, how did the individuals overcome the barriers to change, and what were the resulting benefits?
