HSM 421 Week 1 Discussion 1, Hypothesis in Homeland Security
Choose one of the hypotheses identified in this homeland security document between pages 35 and 141. Read the 3-4 page discussion of this hypothesis and then identify which hypothesis you selected. Explain if you believe the hypothesis you selected is a) declarative b) directional in relationship and c) specific (as described on pages 29-31 in the course text). Conclude by assessing whether or not you believe this is a good hypothesis for research.
HSM 421 Week 1 Discussion 2, Literature Review
Explain the literature review technique used by the researchers for this article on national health security… that are also used in this literature survey. Do you think this literature review was successful in achieving its goal? Support your reasoning with appropriate resources. Respond to at least two of your classmates’ postings.
HSM 421 Week 2 Discussion 1, Quantitative versus Qualitative
Explain the difference between quantitative and qualitative methods. Identify which method of research you believe is most useful in homeland security research.
HSM421 Week 2 Discussion 2, Sampling in Homeland Security
Using the online Ashford Library databases, identify an article that selects a sample from which research is conducted using ethical principles. Briefly describe what type of sample the research utilizes and what methods they use to collect the sample. Determine if you think this is a representative sample and if you think the methods used to get the sample were scientific and ethical.
HSM 421 Week 3 Discussion 1, Evaluating Surveys
Illuminate opinions or research on homeland security. Describe how the survey was designed, how the questions were constructed, and how the results were tabulated. then state, in your opinion, if there areany biases in the survey’s questions or collection methods. Support your reasoning with appropriate resources. DHS Could Better Manage Security Surveys and Vulnerability Assessments. (2012). GAO
HSM 421 Week 3 Discussion 2, Visualizing Data
Visualizing Data. Oftentimes, the way data is visualized and presented is more influential than the research itself. To demonstrate and evaluate this theory, you will watch a visualization of data. Visit and watch the presentations by Dr. Hans Rosling entitled Hans Rosling shows the best stats you’ve ever seen. Hans Rosling describes how international data trends on health can affect the security of nations. Identify at least two types of charts and tables that Dr. Hans Rosling uses to illustrate his data, and answer the following questions: a. Do Dr. Rosling’s research findings become more or less clear with the use of his visualization techniques? b. What are some potential weaknesses you find with using Dr. Rosling’s visualization techniques?
HSM 421 Week 4 Discussion 1, Homeland Security Statistics
Search for and identify a homeland security report that utilizes a frequency distribution to create a histogram. Explain what the report is and what the histogram represents. Annotate the variables that are being …..in the histogram and whether they are nominal, ordinal or interval/ratio variables. Provide a citation to the data report that you chose from the DHS website.
HSM 421 Week 4 Discussion 2, Correlation and Association
Explain what each of these terms mean in statistical analysis. Describe how these two coefficients differ. Conclude by stating which coefficient you believe is most useful in describing relationships between research variables.
HSM 421 Week 5 Discussion 1, Focus Groups in Homeland Security Preparation
Explain how focus group participants were recruited, how the focus group data was collected, and how the results were analyzed. Assess whether you believe if, and where, any bias may have been recorded in this process. Also address whether you think the results of these samples were representative of the Latino population
HSM 421 Week 5 Discussion 2, Elite Interviews
Identify at least two reasons that elite interviewing may not be a sound qualitative research technique in homeland security research. Hypothesize why this technique may be particularly weak in the modern homeland security environment.
