Assignment Details

This discussion has 3 parts:

  1. What effective time management tools should human resources managers use to make effective use of their time when it comes to coping with demands, constraints, and choices confronting them?
  2. What experience do you have with team building? What methodologies have your used with your teams as they pertain to organizing, controlling, planning, leading, and staffing? What obstacles did you face working with your teams? How did you work through them? 
  3. How do human resources managers identify and develop a strategy to deal with employee and organizational development?

DEVELOPING INTIMACY WITH YOUR DATA

This exercise involves you working with a dataset of your choosing. Visit the website, browse through the options and find a dataset of interest, then follow the simple instructions to download it. With acquisition completed, work through the remaining key steps of examining, transforming and exploring your data to develop a robust familiarisation with its potential offering:

Examination: Thoroughly examine the physical properties (type, size, condition) of your dataset, noting down useful observations or descriptions where relevant.

Transformation: What could you do/would you need to do to clean or modify the existing data to create new values to work with? What other data could you imagine would be valuable to consolidate the existing data?

Exploration: Using a tool of your choice (such as Excel, Tableau, R) to visually explore the dataset in order to deepen your appreciation of the physical properties and their discoverable qualities (insights) to help you cement your understanding of their respective value. If you dont have scope or time to use a tool, use your imagination to consider what angles of analysis you might explore if you had the opportunity? What piques your interest about this subject?

(You can, of course, repeat this exercise on any subject and any dataset of your choice, not just those on Kaggle.)

 1. A thin flat plate is positioned in an air flow of 30 m s-1 . The length of the plate in the direction of the flow is 1.0 m. The width of the plate is 0.5 m. The air temperature is 20 oC. The plate temperature is maintained at 80 oC. Determine the heat transfer rate from the plate if: a) the leading edge is smooth (10 marks) b) the leading edge is rough (10 marks)  2. An air duct heater consists of an aligned array of electrical heating elements in which the longitudinal and transverse pitches are SL =25 mm, ST = 25 mm. There are 5 rows of elements in the flow direction (NL = 5) and 4 elements per row (NT = 4). Atmospheric air with an upstream velocity of 10 m s-1 and a temperature of 25C moves in cross flow over the elements, which have a diameter of 12 mm, a length of 250 mm and they are maintained at a surface temperature of 300C.  Determine: a) the air-side heat transfer coefficient (8 marks) b) the total rate of heat transfer (6 marks) c) the temperature of air leaving the duct heater (6 marks)  

Draft Research Paper

Scenario

You are a first-year graduate student. You are taking a graduate course on research and writing. In this assignment, your professor has asked you to write the introduction section of a research paper for a research question/problem in which you are interested.

Instructions

Write the introduction section of a research paper for your professor. This section should:

  • Clearly identify the research question/problem.
  • Pique the readers interest in your research paper.
  • Analyze why the research question/problem is important by reviewing studies that have addressed the question/problem. Summarize groups of studies, not necessarily individual ones. The studies that you cite should be recent, published in the last 5-10 years. Older studies may be cited if they have been widely referenced by others.
  • Evaluate the deficiencies/gaps in the studies.
  • Explain how your research paper will address the deficiencies/gaps of past studies and how it will contribute to the scholarly research.
  • Explain what you expect to find by performing research on this question.
  • What benefits will the findings have and on whom?
  • Establish the purpose and the thesis of your research paper.
