Choose and research a topic related to human biology. Imagine that you are creating a small booklet that will become available at a local health clinic. The booklet should be educational and understandable by the general public. You may select one topic that relates to either homeostatic mechanisms or to a disease that may interest you because of your own health or family history. You will find a list of suggested topics below, or you may come up with your own. If you select a topic that is not listed below, discuss your topic with your instructor before beginning work.
Suggested Topics:

  • Homeostasis: Hydration and exercise, adaptation of the human body to pregnancy, adaptation to cold or hot weather, adaptation to starvation and its consequences, sleep and health, or nutrition and health in children.
  • Diseases: diabetes, heart disease, hypertension, sickle cell anemia, Huntington’s disease, colon cancer, schizophrenia, macular degeneration, hemophilia, Parkinson’s disease, osteoporosis, muscular dystrophy, or hepatitis

Assignment criteria

  1. Select one of the suggested topics above (you may also choose a topic not listed above).
  2. Find articles related to the topic.
  3. Remember that this is a booklet. Write six pages (double-spaced), excluding references. You may include pictures, tables and other material but please include all references. You should cite information in the text from at least five sources (including books, journals, and the Internet). You may not use online encyclopedias as a source more than once. Use APA style for citing references (see http://www.umuc.edu/library/guides/apa.html). All source material should be paraphrased or summarized in your own words. You should have no more than one direct short quote (less than 40 words) and no long quotes (more than 40 words) in your booklet.
  4. The sections of your booklet should include a title; an introduction that defines/describes your topic and what current/ongoing research has discovered about this topic; background information on what healthy organ system(s) is/are affected by the topic; the mechanism of action (e.g., how does the topic disrupt homeostasis? how does a disease spread and infect a person?); its symptoms and how it is diagnosed; current treatment options; prognosis, current and future research, conclusion, and your references. You may include additional sections as necessary to cover your particular topic.
  5. Please keep in mind that the audience for your informational booklet is the general public. Your explanations and uses of evidence, illustrations, or other definitive details should be appropriate for the reader; your language should aid the reader’s understanding of the subject (including definitions where appropriate); you should use information logically, and provide conflicting evidence and research where appropriate.

Part 2 – Run the exercise on the imports-85 dataset and write a report on your findings and interpretation of results in your own words. The report needs to cover the exercise key points below in order.  
Save the commands you run, in an R script.  
 
Download the imports-85.csv file to your hard drive. Click on the dataset description URL and read the dataset description.
http://archive.ics.uci.edu/ml/machine-learning-databases/autos/imports-85.names

  1. Introduction
  1. What is the dependent variable in the auto imports dataset?
  2. What are the independent variables in the auto imports dataset?
  3. What do you expect the multiple linear regression method to accomplish for the auto imports dataset?
  1. Data preprocessing
  1. Load the data into RStudio.  Run the commands to remove variables engine_type, make, num_of_cylinders, and fuel_system.  Include the commands and output in the report.
  2. Discuss any additional data pre-processing commands that you may run. For each command, include the command, command output, and an explanation of the command purpose.
  1. Training and test data
  1. Why do we split the dataset into training and test data?
  2. Run the set.seed(1234) command and the commands to split the data into training set containing 70% of instances and test set containing the remaining 30% of instances.  Include the commands in the report.
  1. Build the multiple regression model on training data
  1. Run the command to build the multiple linear regression model. Store the model in a variable called “model”. Include the command in the report, and discuss the input parameters you used.
  2. Run the summary(model) command.  Include the command and the output in the report.  Answer the following questions about the output.
    • How does the model represent the relationships between dependent and independent variables in the auto import dataset?
    • How does the method handle categorical variables?
    • What does the residuals section of the output mean?
    • What are coefficients, and what do they mean?
    • What is an intercept, and what does it mean?
    • What do the p-values tell us about the significance of each variable?
    • What is the overall accuracy of the model?
  1. Evaluate the model on a test set
  1. Run the command to evaluate the model on the test data. Include the command in the report.
  2. Run the command to build the predicted vs. actual (observed) value scatter plot. Add a diagonal line to the plot (i.e. fit a line).  Include the commands and the plots in the report.
  3. What does the distance between the points and the diagonal line tell about the accuracy of prediction?
  1. Run the plot(model) command to build the residuals plots.   Interpret at least one of the plots.  Include the command, the plot, and plot interpretation in the report.
  2. Minimal adequate model.
  1. What is the minimal adequate model?  Why do we build it?
  2. Run the command to build the minimal adequate model and store the model in the “Model2” variable, include the command and the output in the report.

Model2<-step(model, direction=”backward”)

  1. Run the summary (Model2) command, and answer the following questions.  Include the command, the output, and the answers in the report.
    • Which variables were eliminated and which variables remain?
    • What are the coefficients and the intercept, and what do they mean?
    • Compare the prediction accuracy of the minimum adequate model with the prediction accuracy of the original model.
  1.  Suppose that we have a new car, and we know the values for the independent variables. How would you use the model to predict the value of the dependent variable for the new car?
  2.  Summary
  1. Is the multiple linear regression method appropriate for predicting the values of dependent variable in this dataset?  Explain why or why not.
  2. Which part of this exercise did you find the most challenging and what approach did you take to solve the challenge?

 
Exercise Deliverables
 
Submit the following files in the Exercise 4 Assignment folder:

  • The report addressing the key points above
  • An R script with commands you ran and brief comments on the purpose of the commands

Select a psychoactive drug that is of pharmacological interest to you, but not one you will review as part of your Critical Review. For this paper, you may choose drugs of abuse; however, the paper must focus on the pharmacology of the drug and not on the social or addictive aspects. If you focus on addiction and social impact, your paper will not receive credit.
In addition to the text, research a minimum of three peer-reviewed articles published within the last five years on your selected drug. Prepare a three-page summary of the drug using the PSY630 Rapid Review Example paper (Links to an external site.) as a guide.
In your Rapid Review, analyze and explain the pharmacological aspects of the drug as they relate to the following: neurotransmitters affected, receptors, route of administration, half-life, doses, side effects, drug interactions, contraindications, and other important facets of the drug. Explain these aspects of the drug in terms of the psychiatric disorders indicated for the drug and the issue(s) associated with that use. If there is no accepted therapeutic use for the drug, evaluate and describe the actions of the drug with regard to the abuse process.
