I have already filled in the data in the tables. Just make sure to look at all of the pages I have provided as well as the examples on the page compared to my data. Below I am just reiterating what questions to answer and what to do.
1. Do the curve for the different decades differ from one another? If so, what might have caused the differences?
2. How do your graphs compare with Figure 1, survivorship curves for different types of populations and with Figure 2, survivorship curves for Newberry, South Carolina. Can you explain the differences?
3. How would your data have been altered if your cemetery were still open today and you recorded data for a modern cohort?
Those three questions can be short answers.^
4. Hypothesis: How will your data compare to another cohort (time period)? Why do you think these differences might exist? Use the space below to make a hypothesis. (Complete the chart above this question on the pages I provided.)*
5. One problem with studying survivorship curves is that a birth cohort must be followed through until death of the last individual. How would a 1940’s survivorship curve be altered from those of the 1800’s? (Also complete the chart above this question on the pages I provided.)
6. Speculate about the future if:
A) more and more people refuse vaccinations?
B) medical advances continue and most diseases and infant mortality are eliminated?
C) environmental problems aren’t solved and pollution-related diseases increase?
(Just 3 complete sentences on each question^)
7. Was your hypothesis supported? Write about 1 page (double spaced) summarizing your findings and their relationship to your hypothesis. Speculate on why you found what you did. Include at least one resource (other than what I’ve given you, newspapers are fine)

Critical Appraisal
Critical appraisal of scientific literature is a necessary skill for healthcare students. Students can be overwhelmed by the vastness of search results. Database searching is a skill in itself, but will not be coveredin this blog. This blog assumes that you have found a relevant journal article to answer a clinical question. After selecting an article, you must be able to sit with the article and critically appraise it. Critical appraisal of a journal article is a literary and scientific systematic dissection in an attempt to assign merit to the conclusions of an article. Ideally, an article will be able to undergo scrutiny and retain its findings as valid.
The specific questions used to assess validity change slightly with different study designs and article types. However, in an attempt to provide a generalized checklist, no specific subtype of article has been chosen. Rather, the 20 questions below should be used as a quick reference to appraise any journal article. The first four checklist questions should be answered “Yes.” If any of the four questions are answered “no,” then you should return to your search and attempt to find an article that will meet these criteria.
Critical appraisal of…the Introduction
1. Does the article attempt to answer the same question as your clinical question?
2. Is the article recently published (within 5 years) or is it seminal (i.e. an earlier article but which has strongly influenced later developments)?
3. Is the journal peer-reviewed?
4. Do the authors present a hypothesis?
Critical appraisal of…the Methods
5. Is the study design valid for your question?
6. Are both inclusion and exclusion criteria described?
7. Is there an attempt to limit bias in the selection of participant groups?
8. Are there methodological protocols (i.e. blinding) used to limit other possible bias?
9. Do the research methods limit the influence of confounding variables?
10. Are the outcome measures valid for the health condition you are researching?
Critical appraisal of…the Results
11. Is there a table that describes the subjects’ demographics?
12. Are the baseline demographics between groups similar?
13. Are the subjects generalizable to your patient?
14. Are the statistical tests appropriate for the study design and clinical question?
15. Are the results presented within the paper?
16. Are the results statistically significant and how large is the difference between groups?
17. Is there evidence of significance fishing (i.e. changing statistical tests to ensure significance)?
Critical appraisal of…the Discussion/Conclusion
18. Do the authors attempt to contextualise non-significant data in an attempt to portray significance? (e.g. talking about findings which had a trend towards significance as if they were significant).
19. Do the authors acknowledge limitations in the article?
20. Are there any conflicts of interests noted?
This is by no means a comprehensive checklist of how to critically appraise a scientific journal article. However, by answering the previous 20 questions based on a detailed reading of an article, you can appraise most articles for their merit, and thus determine whether the results are valid. I have attempted to list the questions based on the sections most commonly present in a journal article, starting at the introduction and progressing to the conclusion. I believe some of these items are weighted heavier than others (i.e. methodological questions vs journal reputation). However, without taking this list through rigorous testing, I cannot assign a weight to them. Maybe one day, you will be able to critically appraise my future paper:How Online Checklists Influence Healthcare Students’ Ability to Critically Appraise Journal Articles.

Our history of alcohol regulation in the U.S. has shown how alcohol was consider

Our history of alcohol regulation in the U.S. has shown how alcohol was considered a social, moral, political, and medical problem in different ways from colonial times to the passing of the Anti-Drug Abuse Act in 1988. Alcohol, as we have also seen, is something that both affects personal health as well as the health of others. In at least 200 words examine what you see as the appropriate amount of government intervention in alcohol regulation. In your response, discuss what you think of government regulation of alcohol as it concerns personal health versus the health of others.
In at least 50 words each, comment on the posts of two of your peers. Be sure to say whether you agree or disagree with them, and why.
Carpenter (2010) Introduction
Actions
Read up to the section called “The Scope and Variance of Regulatory Power: Some Comparative and Historical Riddles” (there is a big dotted line before this section)
Note: This reading is not about alcohol regulation, but about the power of the FDA and the federal government to regulate pharmaceuticals. Thinking about the questions and examples that Carpenter raises about the regulatory power of the FDA will help you with the discussion that follows.

DQ 4: Hot Waters

** This is a good point in the semester to discuss making your responses a reflection of your own understanding. It is very tempting to use the copy and paste functions to glean information from your sources into your responses. Directly copying and pasting information is plagiarism. You must be able to put the information in to your own words, so that it shows that you understand the concepts. Blatant copying and pasting will result in a zero for the assignment. **
Discussion Question 4: Hot springs are one manifestation of the heat inside the earth, and of how water circulates fairly deeply in the earth’s crust. They area also sites where microbial extremophiles live – one-celled organisms that survive harsh conditions. They also can be interesting and pleasant places to visit. Using search engines, or library sources, or your own experience, find and report on the following information on a specific hot or warm spring. Put the name of your hot spring in the title of your post.
1) Name of the Hot Spring.
2) Geographic location.
3) Temperature of springs.
4) Nearby associated geologic feature (e.g. volcano, fault, mountains, etc).
5) Other interesting characteristics such as the amount of flow, or unique life associated with the hot spring.
6) Your sources of information.
7) Why did you choose to report on this particular hot spring or geyser?
Once a specific hot spring has been named and described in the discussion board, it is off limits, and subsequent entries for that hot spring will not receive points. I think as the class accumulates this information you will be surprised at how many hot springs there are. Geologic associations should also become clear.
DQ 5: Earth-Sun Interactions

One can learn a lot from looking at the earth from above. In Lecture 7, we discussed how various materials reflect or absorb solar radiation differently. Now it’s your turn! Find an aerial or satellite image of some part of the world on the web, other than those depicted in lecture. Make sure it is an image. (Not a map!) A great variety of sources exist including Google maps (satellite view). Each student should have a unique image. Copy or save the image and include it in your response. The image can be directly uploaded to Canvas, or it can be saved in a Word document. For your assignment, complete the following tasks:
1) Describe in words the geographic location covered by the image. What state, country, etc are you in? What is the latitude, longitude, and elevation? Describe the climate and/or ecosystem are you in (i.e. are you in the mountains? Desert? Urban areas? Wetland?).
2) Make a list of the various earth materials that are reflecting light differently. See Lecture 7b for several examples of this. List out which components in your image have high albedo (high reflectivity) and which ones have low albedo (low reflectivity).
3) Which materials might give off the most energy in infrared at night, and why?
4) Discuss which of these materials and albedos can change over time. Consider a time frame of a) over the course of a year, b) over several decades or centuries d) geologic time (hundreds of thousands to millions of years).
Note: Sometimes it is difficult to determine what features are from the air. Feel free to also look at pictures taken on the ground level to figure out all the features in your area. Google map view and Google street view are great for this!
To help your classmates out, post the location name of your area in the title of your response so that others will know what has already been chosen.
