Population Pyramid Assessment


Research activity

Select one country and assess its population pyramids for this year, and 20 years before and after. Take screenshots of the pyramids to include in your essay. Use those pyramids to assess and reflect on “Population pyramids: Powerful predictors of the future” regarding changes and shifts in your country’s population and the potential for overpopulation. Consider which stage of the demographic transition your country is in. Additionally, you are also required one outside source that addresses birth rate, death rate, life expectancy or migration rate for your selected country.

Items you should note:

The population pyramids and their shape, compared to Figures 3.18 and 3.19 (73-74)

A discussion of demographic transition for your country

A discussion of an additional population statistic from an outside source.

Be sure to record correctly formatted citations for each source you access.

Writing Activity

Using your acquired outside sources and textbook, construct a cited essay of 500-750 words that describes the potential for overpopulation for your country using the data and ideas you have gathered and assessed. Your researched information should be cited, and quoted material should not exceed 15% of the paper.

Sun’s motion

In 2-3 paragraphs, describe thoroughly, clearly, and in detail the pattern of changes easily visible in the apparent position and motion of the Sun in the sky over the course of a year, as observed by ancient astronomers and discussed in our class.

The short answer response will be graded based on its content and thoroughness (60%), the clarity and accuracy of your response (20%), and the use of details , evidence, and examples (20%). For example, if your writing is generally correct, but vague (“Astronomers figured out that the Earth orbits the Sun”), then you may lose points for details and example (When did that happen? Who was involved? What was the evidence?). You should also remember to stay focused and answer the questions; essays that do not directly address the questions given in the prompt–including long essays that wander off topic– will lose points for clarity and accuracy.


One of the key starting points for understanding environmental movements of the past, present, and future is making sense of how we think and talk about nature.

1) In the topic of your post, name an environmental issue you are interested in.
2) Then, post a paragraph (~200 words):
– why this issue is interesting to you, and how you are involved in it (can range from simply learning/reading about it to organizing protests about it)
– connect it to the readings with citations (Author, Date)

3) respond to at least 2 of your classmates, drawing connections to other issues you see posted, relevant readings, current events, etc. (i.e. don’t just say “that’s interesting!,” bring something to the conversation)

This is the classmate discussion post which I want you to respond:
Fires in Southern California
Living in Southern California has exposed me to multiple fires throughout my lifetime that have threatened my, along with countless others, safety and sense of security. For many, the frequency of these wildfires is alarming and is cause for concern, and rightly so. The issue of the increase in impact of wildfires in Southern California is interesting and pertinent to me, not only because it is one that is close to home, but also because it is an indicator of a much larger problem that we face today: climate change. According to the US Forest Service, the chaparral ecosystem is well-equipped and adapted to recover from fires, and fire can actually be an integral component in the regeneration of the species residing there. However, the increased frequency and intensity that has been observed in recent years is counterproductive to growth, which makes it a topic of interest among scientists. My involvement in this issue has been limited to reading about it in the news and in papers. In addition, while taking a class in Conservation Biology, Dr. Jon Keeley delivered a lecture about the ecological impacts of wildfires in different regions of California. I was reminded of this lecture after reading the introduction of Uncommon Ground, in which the author writes about the prominent wildfires that could be seen from Irvine as scientists convened to discuss the manipulation of ecosystems and the definition of nature (Cronon, 1996). This essay caused me to think about how these issues extend through time, and although scientists have been privy to human degradation of the environment and its implications, it continues to persist today.

Community nursing role in improving elderly life

A literature review is a synthesis of chosen evidence and resources on a topic of interest. Your assignment is to select a topic of interest and complete a literature review. You are expected to select a minimum of 5 articles. Your review should be between 6-8 pages (not including title and reference page). It is imperative that  APA (6th edition) formatting is utilized.

Essential Steps of the Literature Review:

Define the research problem/topic
Determine key terms
Select primary sources of evidence
Read and synthesize evidence
Write a synthesis of findings that compares and contrasts findings

Components of a Literature Review


The introduction serves the purpose of presenting the problem and briefly explaining the significance of the topic. You should also share your search strategy with the reader.

Body of Literature Review

The body synthesizes the findings from the studies reviewed. You will first complete an annotated bibliography of each reference. For each study, you should briefly explain the purpose, procedures for data collection, and major findings. Be sure to discuss the strengths and weaknesses of each study.


The discussion section is your opportunity to compare and contrast the evidence you reviewed. How is one better than the other?  How do studies compare or contrast with each other? This is where you draw conclusions based on the available literature.

Reference Page

List all sources utilized to complete the literature review. If it is cited in the body of your writing it should be listed in the reference list. APA 6th edition should be strictly adhered to. Utilize the Writing Center if needed

Any topic (writer’s choice)

Describe what main result you would anticipate seeing in the paper, based on the title alone in as much detail as possible. Its ok if this differs from what is actually found in the paper.

The first sentence of this abstract usually sets up a large, motivating context for the paper. This is the main reason that the authors believe you should consider their work important or the overall context into which the authors believe the work will fit. Restate this context in your own words.

The next sentence usually narrows down the motivating context to a specific area of research and implies an experimental question. Can you state the question or hypothesis in your own words? You can keep moving through the abstract and come back to this if you feel stuck.

Next, the abstract will usually state the main experimental approach (experimental design). Try to summarize the approach in your own words. You could also make a flowchart of the experimental design. Also try to state a hypothesis that could be addressed by the design used. 

What was the main result of the paper? How does it relate to the hypothesis you came up with above?

In the next bit of the abstract, the authors propose some specific mechanisms for the change in the baboons culture. What are they?

The main results of the paper are summarized in the figures. For each figure, please take a look and try to summarize (in a few sentences) the main result that is being conveyed (your notes from our class discussions will be helpful!). If you are thorough enough, you may summarize the figure as a whole. It might also be useful to address each panel individually if you need help organizing your thoughts.

Finally, given your analysis of the abstract, do you think that the results conveyed in the figures actually addressed the goals that the authors stated? What might you have done differently? What else might you want to see or what would you do in a future study (what kind of data would you want to see next)?


Because it draws from other fields such as bio-statistics and social sciences, epidemiology is described as being interdisciplinary. From which aspects of other disciplines do you feel epidemiology borrows? In what ways does epidemiology differ from those disciplines? When responding to your classmates, provide additional connections between epidemiology and other disciplines. Support your response with specific examples.

Physics arguments

(1) Answer the posted “Five Questions about Light”.

(2) Write a 1-page essay on one (just one; pick your favorite!) of the topics , (a) “Light Pollution”, or (b) “Radiation from Mobile Phones: Dangerous or Not?”. As usual, cite on a separate page the references you consulted. In either essay stick to what can be said about the respective topic from a scientific point of view. You may express your personal opinion but only at the very end.

If you pick Topic (a): Describe what is meant by light pollution, what adverse effects it causes and why, and what can/should/will be done to reduce the problem. (Btw and FYI, to raise awareness of the issue, many cities worldwide are involved in “Dark Skies” night, with all but the most essential lights everywhere turned off!

If you pick Topic (b): The issue of potential dangers of the radiation emitted by mobile phones is a highly politicized and emotionally charged topic. Try to de-mystify it by separating facts from speculation as best as you can. (Hint: that’s not always easy!) Start with the website of the National Cancer Institute but also look up and discuss the opposing view.
