Test #2 REWRITES 30 March 2018
ECS 111 Name:______________________________________
Answer question(s) of your choice. For the rewrite, you need to include appropriate references. References must be in the format given in the writing guide. Avoid blogs and other non-permanent references. In considering question five (5), consider the equilibrium states for P and what they mean to the yield. From the point of view of the math, you should be able to work out the equilibria (there are three, the null state P=0 and two possible P >0.). Then analyze the Y for them. In essay form or you should discuss the results.

1) Discuss in simple terms the relationships between soil types/profiles and the biomes in which they are found. How do these and water availability influence agriculture?

2) Describe your favorite animal, its geographic range, and current status (sustainable, endangered, or threatened).

3) Discuss the concept of land ownership. What is the role of government in terms of ownership of land and resources? (Here you may pick a system or contrast a set of government systems.) Give some examples of issues involved either in the past and/or at present.

4) There is major concern over the future of tropical rainforests. What are the issues involved with this debate? What are the explicit ecosystem problems with forest use? Include a discussion of the fate of disturbed forest areas.

5) Consider a population of insect pest, P, potentially infesting a particular area, A, of agricultural land. If the population equation for the insect is then

dP/dt = r P (1-P/αA) – δ A,

where r is the maximum rate of growth in P, α the carrying capacity per area, and δ the damping over an area by application of insecticides.

Now the financial yield, Y, on the crops is reduced by the pest such that the yield equation is

Y = β ( A – γ P).

where β=βo – c δ, reflecting both the crop damage reduction of the gross production, γ P, and the cost involved with insecticide treatment, cδ

Discuss the repercussions (effects) of the pest on farm income in this situation. What are the larger implications that arise in these situations?

Human Reproduction
PowerPoint Presentation
Introduction:
Well, it is that time—yes, time for that talk. For this activity, you will develop a PowerPoint presentation about human reproduction. You are to pretend that the presentation is what you will use to give your son or daughter “the talk” about human reproduction. Make sure you use correct terminology. If you have never created a PowerPoint presentation, make sure you view the CSU Success Center videos suggested in the unit learning activity.
Your presentation must include the following:
– overall purpose of the reproductive systems;
– information about the male and female systems including:
-at least two visual aids illustrating the two systems, and
-structure and function of the major organs of both male and females systems;
-methods of practicing “safe sex” and preventing pregnancy; and
– STDs.
Be sure to follow the formatting guidelines provided below:
– Use bulleted information on slides (5 lines or less).
– Include details in the speaker’s notes.
—Include a separate title slide and a separate reference slide.
– Use appropriate font and backgrounds.
– Include at least nine slides, but not more than 15 slides (not counting your title slide or reference slide).
– Use correct APA format for references and citations, and use correct grammar and spelling.
– Upload the presentation as a .ppt or .pptx file.

Paper Students will be required to watch 4 documentaries outside of class.  These documentaries are found by linking to the following  websites:
1A.  The Trouble with Antibiotics 10/14/2014: http://www.pbs.org/wgbh/pages/frontline/trouble – with – antibiotics/
OR 1B. Hunting the  Nightmare Bacteria 10/22/2013: http://www.pbs.org/wgbh/pages/frontline/hunting – the – nightmare – bacteria/
AND 2. The Vaccine War 03/24/2015
http://www.pbs.org/wgbh/pages/frontl ine/the – vaccine – war/
3. Supplements and Safety 01/19/2016: http://www.pbs.org/wgbh/frontline/film/supplements – and – safety /
AND 4. The Weight of the Nation Part 1 05/14/2012: https://www.youtube.com/watch?v= – pEkCbqN4uo
– Please note that there are images that some would deem as graphic between 38 – 41 minutes.  You may skip over this  section if you are so inclined. Students will be required to  complete  a 3 – page discussion paper on  two of the documentaries.   
You are required to select one of the three documentaries related to infectious diseases  AND one of the two documentaries with  chronic/environmental exposure diseases .  This assignment is due by  04/06 /2018 midnight . You may turn it in early if you so desire.   
I AM  NOT LOOKING FOR A SUMMARY OF THE 2 DOCUMENTARIES THAT YOU HAVE SELECTED.  Using information  provided in the documentary  AND outside research material, you will be asked to discuss each documentary  topic that you selected AND to compare and contrast differences between the disease issues.   Please remember to refer to  epidemiological terms and the math that is associated with presenting these diseases.   Using the outline provided in the textbook  and course notes (Chapter 1, see attach file), please describe, explain, predict, and discuss control methods of the disease or  behavior you have selected.   o Items you may want to consider  describing in your paper/presentation could include, w hat is the incidence and  prevalence of the disease?  What is the epidemiological and financial impact/burden of the disease at a regional, national,  and international level?  What techniques do epidemio logists use to address, control, or reduce the number of cases of  this disease?   What stigma or  psychological issues might epidemiologists need to be aware of when collecting data and  implementing control methods? o You may want to seriously consider referr ing to refereed journal articles when presenting your findings.  Websites are  not considered refereed journal articles. 
Discussion paper criteria: This paper  needs to be in your words and not  plagiarized .   The minimum requirements for this  paper will be a  3 – page minimum/ 4 – page maximum, single space, 1 – inch margins and no more than 12 – point font . Take the  time to fully describe the selected disease/behavior and its impact to public health.   Please be thorough when describing the  epidemiological principles

HCA 383 Biostats Lab Assignment 2

HCA 383 Biostats Lab Assignment 2
This assignment is due by 11:59 pm, April 5th, 2018.

Important: Please make sure you are using the right dataset in each question. Datasets will be referred to by their names in each question.

Wherever necessary, variables associated with any part of the analysis will be mentioned by their names as they appear in the dataset and will be enclosed in parentheses; for example: How many people are Hispanic in the sample (RACE). This means you need to perform the relevant procedures using a variable called RACE.

When you produce SPSS output in your response make sure you submit only the relevant part of the output. SPSS produces a lot of information that you do not need to submit. SPSS output can be copied and pasted into a Word document. But remember, submit only the relevant part of the output!

Be sure to assign missing values so that you can account for people who responded “don’t know” or refused to answer the question.  Steps are given below.

1. Use the dataset you created in Assignment 1 to answer the following questions: [Create it again if you did not save it—more practice!]

(a) What percentage of the individuals in the sample did not have private or public insurance? (INS_TYPE). (2 points)

(b) What is the average age of the individuals in the sample? (AGE). (2 points)

(c) What is the total percentage of respondents who were either unsatisfied or very unsatisfied with the services? (PTN_SAT). (2 points)

(d) What percentage of the sample did not graduate from high school? (EDUC) (2 points)

2. Collection of patient data

Each time a patient enters a health care facility seeking care for him/herself there is a certain amount of data that is collected from each patient.  Some of this data are quantitative data and some data are qualitative data.

(a)  What are the differences between quantitative data and qualitative data?  (4 points)

(b)  Give three examples of each type of data that are collected in a health care encounter (that is: when a person goes to see the health provider). (3 points)

(c) State at least THREE different techniques that can be used in the collection of SURVEY data. (3 points)

3. Use the dataset named “webhealth.sav” (located in the Blackboard Datasets folder) for this part of the assignment:

First, follow these steps to assign missing values: Let’s use the ‘inc’ variable as an example.

· Go to the Variable View of your dataset

· Look for “Missing” column next to the “Values” column

· Scroll down until you find the “inc” variable

· Click on the “Values” for that variable and look at what are all the values are and then identify what numbers should be used as the missing values for this variable.

· Click on None in the Missing column for that variable and add the two discrete values for the missing (each number in its own box).

· Click ok.

Now here are the questions you need to answer.

(a) What percentage of the respondents were residents of suburban area? (usr). (2 points)

(b) What is the difference between the “Percent” and Valid Percent” columns on SPSS output?  Give a reference for your answer. (3 points)

(c) Find out what weekly frequency of using internet or email from home is represented by 21.3% of the respondents and 5.4%? (q8a). (3 points)

(d) What percentage of the respondents have ever used their cell phones to access health or medical information? (q15). (2 points)

(f) What is the average age of the respondents? What is the range of their age? (age).  Be sure to exclude data that is missing. (2 points)  Look this up under the values for age and assign missing values for the age variable using the steps you used previously.

(g) What is total percentage of persons who were in school (either as full-time or part-time students)? (stud) (2 points)

Best wishes.
