You are required to deliver a presentation that demonstrates your understanding of human immunity. Your presentation must include the three sections outlined below.
SECTION ONE
Show that you understand non-specific defences against disease by describing the first and second lines of defence giving specific examples, e.g. barriers to infection, inflammation, fever, role of macrophages etc.
You should use diagrams to support your commentary where appropriate.
SECTION TWO
Demonstrate that you understand specific immunity by covering the areas below.
• Explain the third line of defence e.g. acquired immunity and sensitivity to antigens, the roles of different types of immune cells and immunoglobulins.
• Explain self-recognition and tolerance to own tissues and rejection of transplanted organs.
• Describe two specific immune system disorders e.g. Rheumatoid Arthritis, Lupus, Multiple Sclerosis (MS) Dermatographia, etc.
You should use diagrams to support your commentary where appropriate.
SECTION THREE
Show that you understand the biology of vaccination by covering the criteria below.
• Describe the categories of acquired immunity including natural, artificial, passive and active.
• Explain the immune response to vaccination including immunological memory.
• Evaluate the benefits of vaccination by analysing measles infection rates in the UK between 1940 and the present day.
• Discuss the concept of herd immunity, vaccination programmes and factors effecting vaccine uptake.
You should use diagrams to support your commentary where appropriate.
GUIDANCE
You will need to produce a set of slides using PowerPoint or similar software. You can then use these to support the delivery of your presentation. Any notes that you have used to support the delivery of your presentation must also be submitted.
Your presentation will need to be video recorded and the relevant file submitted as part of your assignment. The video must clearly show you delivering the presentation with your slides in the background. A copy of the slides you have written and used will also need to be submitted.
Your presentation should be a maximum of 20 minutes in duration.
This time limit is the absolute maximum you are permitted. If you are over the time limit for this assignment in any way you will receive your assignment back without further comment or feedback.
Refer to the study materials in the ‘Academic Writing Skills’ unit for detailed guidance as to how to structure, produce and deliver a presentation.
Refer to pages 14-15 of your course handbook for guidance as to how to upload your video file to the system.
Relevant theory must be referenced where appropriate and a references list provided. Your presentation should also contain appropriate diagrams to support your commentary. If these are taken from published sources they must be referenced accordingly.Hide Assessment Criteria

The definition of the situation by an actor
is seen as critical to understanding behavior. However, some critics have said
that this emphasis on the actor’s perspective neglects the importance of the
actual reality and heightens the importance of a psychological investigation.
What is the correct weight researchers should give individual perspective on
context versus the actual context in understanding behavior? Do you believe
that there is an “actual reality,” or is it all just individual perceptions?

The following information, describing a
patient, is in random order. Organize the information and present a medical
radio report as if you were radioing the hospital.
• Chest pain radiating to the shoulder •
Fifty-six years old • Oxygen applied at 15 liters per minute via nonrebreather
• Alert and oriented • Female • Came on twenty minutes ago while mowing the
lawn • History of high blood pressure and diabetes • ETA twenty minutes • Pulse
86, respirations 22, skin cool and moist, blood pressure 110/66, SpO2 96
percent • Oxygen relieved the pain slightly • Denies difficulty breathing • You
are requesting orders from medical direction • You are on Community BLS
Ambulance 4 • Lung sounds equal on both sides • Placed in a position of comfort

Note: You need to submit your answers in a word document. You need to transfer the results from the excel file into the word document. In addition, you must submit your Excel file (we prefer a single excel file with one or multiple worksheet for each question) but note that only the word document will be marked. If you think there is any issue or unclarity in any question, please make your assumptions (if there is any) and clearly explain them in your report.
You need to add the coversheet and sign it. Please write the name of your tutor as in the coversheet.
The analyses and the answers must be your own individual work without consultation of any other person. Also, you are not allowed to help/advise other students.
Open excel sheet which is called worksheet “Q1” of the Excel file (provided for this assignment) and develop the following visualizations: (3+3+3=9 marks).
A figure showing whether there is a relationship between age and income.
A figure showing distribution of income.
A figure illustrating registration date and frequency of people who are registered.
Excel worksheet “Q2” is related to a financial institute that provides loans to its customers. The intention from investigating the data is to identify the customer credibility. The description of variables are presented below: (5+6=11 marks)
Variable
Meaning
Credibility
1= good
2= bad
Credit amount
No description needed
Length of employment
1= less than 20 years
2= between 20 and 40 years
3= between 40 and 60 years
Sex and Marital Status
1= married made
2= married female
3= divorced male or female
Age
Age in years
Considering we want to develop a model and consider credibility as a dependent variable answer the following questions:
How many independent categorical and numerical variables exists in the data set?
If we want to develop a logistic regression model how many coefficients would we have excluding intercept.
The data presented in worksheet “Q3” is the results of a 4-year study conducted to assess how age, weight, and gender influence the risk of diabetes. Risk is interpreted as the probability (times 100) that the patient will have diabetes over the next 4-year period. What predictive model you suggest relating risk of diabetes to the person’s age, weight and the gender. Why? (5 marks)
There are 500 client records in the worksheet “Q4” of the Excel file (provided for this assignment) who have shopped many special products from an e-Business website. Each record includes data on types of product purchased (between 1-5), purchase amount ($), age, gender, family size of the customer, whether the client has a membership and whether the customer has a discount card. (8+7=15 marks)
Develop a multiple regression model to predict the spend amount based on other variables in the data set. Write the final equation and interpret the coefficients of the model and explain the accuracy of the model?
What would be your recommendation to improve the accuracy of this model? What is your recommendation to improve the simplicity of the model?
The following screenshot is taken from the logistics regression output from a data set which can be found here. The data set is about blood donation of a center. In this data set, there are four dependent variables and one independent variable. Independent variables are explained below. Dependent variable is if another donation happened in March 2007.
R
months since last donation
F
total number of donation)
M
total blood donated in
T
months since first donation
(8+7=15 marks)
Write the logistics regression equation based on the output?
In the Excel sheet “Q5” you can find the actual values of dependent variable versus the prediction values in the test set. Calculate overall error, sensitivity, and specificity. Explain the steps of calculations.
Consider the following confusion matrix as the result of a logistic regression model that aims to classify a dependent variable y (whether the patient is having heart attack or not) based on a given set of independent variables. In this model, y = 1 indicates having a heart attack and y = 0 indicates not having a heart attack. The cut-off value is considered as 50%. Do you think we need to make a change to the cut-off value?
