Reflection Paper- Anthropology

Given the severe shortage of trained medical personnel, especially in rural areas of low-resource countries, many medical anthropologists have suggested incorporating traditional healers into health care and health education initiatives. However, this idea has been controversial. Review the Steinglass article and think about the various of sides of this debate. Should traditional healers be actively incorporated into our response to the HIV/AIDS crisis? Develop a stance, and using evidence from readings, lecture, Ted talks etc., defend your position.

Question And Answer

Gwyneth Jones’s Global Climate Change Links & Resources List

This last modified: Sunday, 6/15/14

Please do send additional suggestions – I will keep expanding this list

How do you know what you know?…And how will you know if you’re wrong?

What do you (think you) know about global climate change?…

Pre-Learning SURVEYS: Which of the “6 Americas” would you say you are? — Alarmed, Concerned, Cautious, Disengaged, Doubtful, Dismissive (Yale U & George Mason U) — Added 2/4/14 Survey #1: Global Warming/Climate Change Survey #2: Science, Economics, Government Denialism: What Is It And How Should Scientists Respond? (Diethelm & McKee, 2009) – .pdf — Added 2/4/14 NOTE: If you are not already in one of my classes and you decide to take one or both of these surveys — or a related one not listed below — I would be very interested in a copy of your results! 🙂 ~GJ

Pre-Learning “FACT or OPINION?” Scientific Method Activity & Logical Fallacies: — Added 2/4/14

A fact is something that is true and is supported by evidence. An opinion is something you believe or feel to be true and is open to debate. A logical fallacy is a flaw in reasoning. Grades 3-12+: Full document .doc or .pdf (17 pages) – Examples given are: Trees, groundhogs, plate tectonics, global climate change

Or just the handout (5 page .pdf) or extra images (1 page .pdf) or fallacies bkgd (11 page .pdf) PreK-Grade 5: Coloring & Drawing .doc or .pdf (5 pages) NOTE: This is adaptable for all ages, PreK through college. (I’ve found it interesting to hear my 3- and 6- year-olds discussing what is fact vs. what is opinion.) If you use or adapt it, I would be very interested in your feedback. 🙂 ~GJ

Climate Change Evidence, Impacts, and Choices: Answers to Common Questions about the Science of Climate Change (“Responding to climate change is about making choices in the face of risk.” ~NRC)

Part I. Evidence for Human-Caused Climate Change How do we know that Earth has warmed? How do we know that greenhouse gases lead to warming? How do we know that humans are causing greenhouse gases to increase? How much are human activities heating Earth? How do we know the current warming trend isn’t caused by the Sun? How do we know the current warming trend isn’t caused by natural cycles? What other climate changes and impacts have been observed? The Ice Ages Part II. Warming, Climate Changes, and Impacts in the 21st Century and Beyond How do scientists project future climate change? How will temperatures be affected? How is precipitation expected to change? How will sea ice and snow be affected? How will coastlines be affected? How will ecosystems be affected? How will agriculture and food production be affected? Part III. Making Climate Choices How does science inform emissions choices? What are the choices for reducing greenhouse gas emissions? What are the choices for preparing for the impacts of climate change? Why take action if there are still uncertainties about the risks of climate change? Conclusion

Environmental Homework

ENV 3001 – Global Learning (GL) Assignment

This assignment provides a brief background on materials use and waste management. There are

two topics provided:

Topic 1: Endangered elements

Topic 2: Persistent waste materials in the environment (e.g., plastics)

The GL assignment should be submitted via Canvas before the last class of the semester

(Thursday June 13, 2019).

Assignment:

Select only one of the topics and discuss the issue and develop an overview of the problem as

described in the Topic below. Your report should address the points as indicated, estimated of

quantities, materials and other relevant information. Please limit your report to 2-4 pages

(appendices are OK) including figures, tables, calculations, references.

Extra credit: I have provided a paper to read: “From electronic consumer products to e-wastes:

Global outlook, waste quantities, recycling challenges”

Provide a brief discussion (1 page) on the global cross boundary transport of e-wastes.

Background

There has been significant technological advancements since 1950s. Technology adoption rates

and product replacement cycles create challenges for materials supply and management of

discarded products.

 

 

Fig. 1. Major advancements since 1990.

 

Fig. 2. Technology penetration.

 

Fig. 3. Product marketing and consumer purchase cycles. Note that disposal is not a main

consumer issue.

 

Fig. 4. World Population

 

Fig. 5. Most densely populated regions in the World.

 

Fig. 6. Water scarcity in the World.

 

Fig. 6. Growth of World population and the history of technology.

 

Topic 1: Endangered elements

 

With rapid growth in innovation and technology development over the past several decades, an

increasing number of elements in the periodic table are now used in advanced consumer products

to perform specialized functions. At the same time, with the decreasing cost and increasing

availability of the consumer products and their short use cycles; there has been increasing

concerns regarding the availability of some of the elements in the future. The concerns for supply

of materials and necessary elements include:

 projected production quantities

 available markets and projected market potential for products

 changes in production or in available ore deposits in different countries

 geopolitically concentrated production of materials

 minimal or lack of end-of-life recycling efforts

The following periodic table has been developed by the American Chemical Society to bring

awareness for the rate of utilization of some elements which are likely to be available in limited

quantities.

 

Select one of the endangered elements and discuss:

a. where it is produced b. where it is used c. production rate and consumption rate d. provide preliminary calculations for people using and discarding a specific type of

products where these materials are used

 

Topic 2: Persistent waste materials in the environment (e.g., plastics)

Decomposition characteristics of plastics in the environment depends on both the conditions in

the environment and the characteristics of the polymeric material. Since majority of the plastics

present in MSW are sensitive to photo oxidation, they can remain stable for longer times in the

landfill in comparison to their transformation behavior when they are exposed to sunlight (i.e.,

floating on the sea surface). A wide variety of chemical additives are incorporated into the

plastics. Some additives are designed to stabilize the polymer and make it more resistant for

degradation. For example, anti-oxidants and stabilizers used as additives inhibit the degradation

of the polymer, while pro-oxidant additives make the plastics more sensitive towards

degradation. Presence of starch increases biodegradability of plastics; however, biodegradation

of starch will not work without a pro-oxidant. The additives used in plastics are usually not

covalently bonded to the polymer. Therefore, they can leach out from the plastic material as it

degrades. Thus degradation rates of the plastics (even those with added starch) depends strongly

on the type and amount of additives used. The half-life of most plastics is over 100 years in

landfills or the environment.

 

 

PP: polypropylene, PS:polystyrene, PET: polyethylene terephthalate, LDPE: lowdensity polyethylene, HDPE: high

density polyethylene PVC: polyvinyl chloride

Select one type of plastic (PP: polypropylene, PS:polystyrene, PET: polyethylene terephthalate,

LDPE: lowdensity polyethylene, HDPE: high density polyethylene PVC: polyvinyl chloride) and

discuss:

a. where it is used b. how much is used and discarded c. provide preliminary calculations for use and discarding rates of the specific type of

plastic

OSHA Case Studies

Please submit 3 separate word documents.

1.You managed to schedule an informal conference with the area director at the regional OSHA office four days after you received the Notice of Citations and Penalty. Based on the citations and penalties you received in Unit III, prepare a document that lists the citations and penalties you wish to discuss with the area director.

You should summarize what you are trying to accomplish in regard to each citation/penalty you choose, to include:

  • the      information you will use to try and accomplish your goal,
  • the      information you will take with you to the meeting, and
  • who      will accompany you to the meeting.

You must support your actions with reliable sources. Your grade will be based on your ability to present a case to your professor (serving as the area director) to reduce either the severity of some citations or the amount of some penalties. If you simply state that you accept the citations and penalties as written, you will receive a minimal score on the assignment. Your response must be a minimum of two pages in length, not including the title page and reference page. You must use at least one reference in the paper. All sources must be cited in the text and on the reference page, using APA style.

2. You fail to reach an informal settlement agreement with the area director. You file a Notice to Contest within the required 15-day period. Your case is assigned to an administrative law judge (ALJ). Prepare a document summarizing the case you will submit to the ALJ. The document should, at a minimum, discuss the following issues:

  • which      citations and penalties you would contest,
  • the      reasoning behind each contested citation and/or penalty,
  • documents      you would bring to the hearing,
  • individuals      you would use at the hearing,
  • how      the case before the ALJ differs from the informal conference,
  • what      information will be presented before the ALJ that was not presented in the      informal conference, and
  • what      information you would request from OSHA as part of discovery.

You must support your actions with reliable sources. Your grade will be based on your ability to present a case to your professor, serving as the ALJ, to reduce or vacate either the severity of some citations or the amount of some penalties. If you simply state that you accept the citations and penalties as written, you will receive a minimal score on the assignment.

Your response must be a minimum of two pages in length, using at least one reference. All sources must be cited in the text and on the reference page, using APA style.

3. Assume that a fatality occurred at your facility one month prior to the OSHA inspection. Review the citations and penalties that were assessed to your facility, and respond to the following questions:

  • Which      of the citations could be referred to the U.S. DOJ for criminal      proceedings?
  • What      conditions would have to be met before the citations could be referred for      criminal proceedings?
  • Which      individuals working at your facility could face criminal charges under the      act?
  • What      would be the maximum prison sentence and fines that any individual would      face?
  • What      would be the maximum fine that the company would face?
  • If you      were facing criminal charges under the act, what would be your best      defense?
  • How      could you involve the OSHRC in the criminal case(s)?

Your response must be a minimum of two pages in length, using at least one reference. All sources must be cited in the text and on the reference page, using APA style.
