    **Ch 13-15 Discussion (p)**

    **You have three topics to choose from in Part A**

    **Question #1: The Presidency**

    Many of the founders were worried that the office of the President would gain too much power, so the authority of the presidency was limited in a variety of ways. In fact, the title "President" was chosen because, at the time, it did not carry weight and implied authority of "King" or "Monarch". Since then, however, the power of the presidency has expanded dramatically. There are a variety of reasons that the power of the presidency has expanded since the time of the founding, including changes to how presidents are elected, the expanded scope of activities undertaken by the federal government, the administrative power of the presidency, and the President's ability to communicate directly with the public. Discuss which of these factors were most important in expanding the powers of the presidency, and the pros and cons of the President having more power today than the founders originally intended.

    **Question #2: Bureaucracy in a Democracy**

    Most people have only a vague understanding of how the federal bureaucracy works. We may have had a bad experience with the IRS, or a nice time at a federal park, but the federal bureaucracy touches our lives in many more ways. Often, our lives are shaped by bureaucratic actions that we don't even know are taking place.

    With that in mind, what in the reading this week surprised you the most? Feel free to address a function that you didn't know that the federal bureaucracy serves, ways that the bureaucracy interacts with Congress, how the public or interest groups can influence bureaucratic decisions, how the bureaucracy has changed over time, or any other topic that you found surprising and informative.

    In your response, try to describe how your newfound understanding of the bureaucracy changes the way you think about American government more broadly.

    **Question #3: The Federal Courts (A)**

    Once appointed, federal court justices serve until they die or choose to retire, which has both positive and negative consequences. Discuss the benefits of federal judges serving for life and the potential problems that this feature of our judicial system can create. Having weighed both sides of the question, argue whether lifetime appointments make sense today. If you do not support lifetime appointments, propose an alternative that could still accomplish the positive aspects of federal judges serving for life.

    **Part B**

    **_Answer two of the questions below and comment on your classmates' answers._**

    1) Imagine the United States is facing a major crisis, like a pandemic or a national security threat. You are part of a government task force. Do you prioritize giving the federal government more power to act quickly (Federalist approach) or limiting government power to protect individual liberties (Anti-Federalist approach)? Explain your choice and consider the possible consequences of your decision

    \_\_\__________________________________________________________________________

    2) Suppose a new law is proposed requiring all states to follow a uniform education curriculum. Some states argue this limits their freedom to set their own standards. Would you support giving the federal government the authority to enforce the curriculum (Federalist view) or protecting the states’ rights to make their own rules (Anti-Federalist view)? Explain the potential benefits and risks of your choice.

    \_\_\___________________________________________________________________________

    3) Imagine the government wants to implement a nationwide surveillance program to prevent crime and terrorism. Would you argue that individual rights should always come first, even if it limits government efficiency (Anti-Federalist perspective), or that granting more government power is justified to protect the greater good (Federalist perspective)? How do you balance safety with liberty?

    Assignment Prompt & Instructions

    **Combining internet research and critical thinking, you will explore key milestones and potential concerns related to the aging brain. This assignment is designed to help you demonstrate your understanding of how this essential organ changes over time. Begin by selecting any two ages you are interested in learning more about, then:**
    – **Compare and contrast** brain development and function at both ages. For example, you might look at the brain at two years old versus nine years old.
    – **Summarize** the cognitive abilities and/or possible age-related effects for each group.
    ### **Step 1: Research**
    Start by gathering information on brain function and development for the two ages you’ve chosen. Use credible sources such as those found in our Online Library (opens in a new window) or through scholarly internet searches. **Do not use Wikipedia.** You must include information from **at least two different sources** and avoid relying solely on one website.
    ### **Step 2: Write**
    Using what you’ve learned, create a written analysis that is **two to three pages long**. Your document should be formatted in APA 7th gen style (12-point font, double-spaced), and your discussion must be supported with properly cited research and in-text citations. Submit your work as a Word document

    ## QSO 321 Module Four Journal Guidelines and Rubric
    ### Scenario
    You are the chief operating officer (COO) of a local supermarket chain that has 10 stores within a 100-mile radius. The farm-to-table movement has been gaining momentum locally, and now it is a consumer demand and a good practice. This movement supports the use of local suppliers to limit the environmental impact caused by the long-distance transportation of food. It also supports small family farms that use sustainable practices, such as avoiding genetically modified organisms and pesticides or using organic fertilizers. The chief executive officer (CEO) of the supermarket chain has asked you to see if the supermarket can apply some of the farm-to-table principles to how it selects produce suppliers. Before moving too far in that direction, both you and the CEO agree that the inventory management implications need to be understood.
    Keep in mind that supermarket customers want a wide range of produce all year long—even produce that does not grow locally during parts of the year. For example, oranges cannot survive very cold weather, but local customers expect to be able to buy them even during snowstorms in the winter.
    ### Directions
    For this journal, address the following **rubric criteria**:
    – **Incorporated Farm-to-Table Principles:** Identify different ways the supermarket chain could incorporate farm-to-table principles into its operations while still meeting consumer demands.
    – **Benefits and Risks:** Explain the benefits and risks associated with incorporating farm-to-table principles into the grocery chain’s supply chain.
    – **Data and Communication:** Describe how data and communication with the local farms are necessary for the supermarket to implement this endeavor.
    – **Factors or Metrics:** Identify factors or metrics that will determine whether you, as the COO, will support applying farm-to-table principles to the supermarket and explain why.
    ### What to Submit
    Submit your assignment as a Microsoft Word document with double spacing, 12-point Times New Roman font, and one-inch margins.

    ### Overview
    In this assignment, you will apply what you have learned about key concepts regarding operations management. You are encouraged to leverage your work and instructor feedback on this assignment in your course project, which is due in Module Seven.
    ### Scenario
    You are the chief supply chain officer at NationaliTeas, a large international corporation that manufactures and sells tea worldwide. Its mission is to “Make the world more awake through rejuvenating and refreshing beverages and sustainable practices that uplift workers, communities, and souls.” You have recently hired the company’s first project manager and assigned their first project: Revise workflows in use related to packaging at one of your tea factories to be more sustainable and leaner. As this is their first project, you will be helping them complete the task.
    ### Directions
    Read the Project Charter for Workflow Improvement, then review the Process Workflow for Tea Production graphic. These documents are linked below under Supporting Materials. A text-only version is available: Process Workflow for Tea Production Text-Only Version. Based on these documents, recommend removing a total of **four** steps from the process flowchart that can help make the process more efficient and sustainable. Explain the implications of the proposed changes and then help the NationaliTeas team address existing items in the Issue Log located in the project charter.
    Specifically, you must address the following **rubric criteria**:
    – **Lean Manufacturing**: Evaluate the process flowchart to identify steps that do not add value based on the principles of lean manufacturing. Explain why you selected each step.
    – **Sustainability**: Evaluate the process flowchart and identify steps that should be removed or changed to improve environmental sustainability. Explain why you selected each step.
    – **Process Changes**: Explain the implications, both positive and negative, of removing or changing the steps from the process flowchart you identified in the previous two bullet points. Also, explain how those changes would help alignment to the triple bottom line (TBL).
    – **Issue Log:** Analyze all entries in the Issue Log from a project manager's perspective. Explain the recommended course of action based on the project charter, noting the impact of the issue on scope, planning communications, and resourcing.
    – **Operations Management Techniques**: Discuss how operations management techniques, including project management and lean manufacturing, can add value to the organization, NationaliTeas.
