## Determine the ideal number of clusters.

Included with this assignment is an Excel spreadsheet that contains data with two dimension values.

The purpose of this assignment is to demonstrate steps performed in a K-Means Cluster analysis.

Review the “k-MEANS CLUSTERING ALGORITHM” section in Chapter 4 of the Sharda et. al. textbook for additional background.

Use Excel to perform the following data analysis.

Plot the data on a scatter plot.
Determine the ideal number of clusters.
Choose random center points (centroids) for each cluster. (Note: Each student will select a different random set of centroids.)
Using a standard distance formula measure the distance from each data point to each center point.
Assign each data point to an initial cluster region based on closeness.
For each cluster calculate new center points.
Repeat steps 4 through 6.
You will use Excel to help with calculations, but only standard functions should be used (i.e. don’t use a plug-in to perform the analysis for you.) You need to show your work doing this analysis the long way. If you were to repeat steps 4 through 6, what will likely happen with the cluster centroids? The rubric for this assignment can be viewed when clicking on the assignment link.

Here is a link to an example spreadsheet using a smaller data set. It contains two tabs. The first tab is the raw data. The second tab contains the analysis that was performed. Make sure that you use a different starting center points from the example.

What is the value of his investment after (a) 15 years (b) 20 years (c) 25 years and (d) 30 years? If the investment earned only 3 percent annual compound interest what would be the values? From the results obtained what conclusions can be drawn regarding the impact of the interest earned versus the duration of the investment? Six percent annual compound interest: (a) (b) (c) (d) Three percent annual compound interest: (a) (b) (c) (d) The single sum compound amount factor answers the question regarding the impact of the interest earned versus the investments duration. Because the duration () is in the exponent time is far more critical than the interest rate earned on investments. For that reason it is essential that an individual begin investing sooner rather than later. how do they get 47.57542 in example D im putting in 1.06 ^ n on each one Show less

## What are others attitudes toward you?

Unit II Reflection Paper Being new to a place is challenging. The list below includes some provocative discussions related to the events in this unit’s reading and related to being new to the United States. For this assignment, you will write two reflections on Parts 1 and 2 below.

The total length of your journal assignment must be a minimum of three pages in length, with each journal entry being at least one page. (For example, this means that you could have one reflection be one page and the other be two pages, each could be one and a half pages, or some other means by which each is at least one page in length and your total overall pages total three.)

HY 1120, American History II 3 The reflections will need to reflect your understanding of the time period and need to avoid being anachronistic. (Remember that this term loosely means to apply today’s values or perspectives on the past.) To accomplish this, you will need to write both reflections as if you are a first generation immigrant (in the first person). Your first reflection entry needs to be from the viewpoint of an immigrant from Europe (e.g., Ireland, Italy, Germany, England, or France). Your second reflection entry needs to come from the standpoint of an immigrant from Asia (e.g., China or Japan). You will need to develop an argument within both reflections entries based on the bulleted items below. In your own words, justify academically the side of the argument you choose, remembering to cite your sources along the way.

Part 1

 Are you treated as an equal by earlier generations residing here?

o What are others’ attitudes toward you?

o Why do you think they act this way?

 Would you feel pressured to pledge your loyalty to a political machine?

 Would you agree to engage in a strike?

 Talk about some leisure opportunities and how they are divided by race or class or are for everyone.

Part 2

 What is the “American dream?”

 How did the growth of big business impact the American dream?

 Explain which leisure opportunities could be part of the American dream.

 What part did the anti-immigration sentiment play in the American dream?

As this is a point of view essay, a modern perspective will not accurately address what the question is asking for. It is strongly suggested that you use at least one selection from the America: History and Life with Full Text database within the CSU Online Library. All sources used, including textbooks, must be referenced; paraphrased and quoted material must have accompanying APA citations.

## Examine performance management issues and processes.

You are the HR manager for an upscale retail store which sells clothing, shoes, handbags, and other accessories. Due to the economic downturn, the company has experienced a significant reduction in earnings, resulting in the layoff of a number of retail sales associates. Business seems to be rebounding, but you are concerned about the performance of the retail sales staff. The CEO has requested that you recommend ways to increase sales and customer service. You believe that implementing a performance management system may help modify employee behavior and improve results.

Write a six to eight (6-8) page paper in which you:

1. Create a job description for a retail sales associate, which includes the most significant components necessary to describe the job both internally and externally.
2. Create an organizational behavior modification (OBM) plan to define four (4) key behaviors that are required for successful job performance as a retail sales associate. Suggest the significant ways that your plan will benefit the organization.
3. Specify two (2) ways that you would measure whether current employees exhibit the key job performance behaviors. Propose two (2) methods that you could use to inform employees of the new performance standards.
4. Outline a plan with two (2) methods of providing feedback to employees. Include the frequency with which the feedback will be provided. Propose two (2) actions company leaders should take to reinforce positive employee behaviors.
5. Examine at least three (3) key legal and ethical issues that could potentially impact the performance management system. Support your response with specific examples of the identified issues’ possible effects on the performance management system.
6. Use at least four (4) quality academic (peer-reviewed) resources in this assignment. Note: Wikipedia and other Websites do not qualify as academic resources.

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

• Examine performance management issues and processes.
• Examine the influences on and various approaches to compensation.
• Use technology and information resources to research issues in human resource management foundations.
• Write clearly and concisely about human resource management foundations using proper writing mechanics.
