Case Studies

In Case Study 9, Building Trust in Communities: The Narragansett Indian Tribe and the State of Rhode Island, The Natives had a longstanding history in Rhode Island. In the U.S., the federal government has a history of taking land, claiming it and then isolating the Native community from resources and opportunities. This case study is only one example. The Narragansett filed suit again the state and individual landowners to reclaim the land the tribe asserted rightfully belonged to them. The Federal government ended up giving the Natives 1,800 acres of land in a settlement and sovereignty over the land.

Today, there is still a fight with Native tribes about land and resources. As a result, Natives tend to face a plethora of public health issues.

a. Name at least three of the socioeconomic factors or behavioral risk factors, that contribute to health disparities among Native populations, currently (If necessary, Use data from Centers for Disease Control and Prevention to support your answers. You can also use  the Bureau of Indian Health Services)   b.  Explain why these factors are public health issues using current data. c. Provide one example of potential prevention strategies for each of the factors, that you listed and described, using current or modern day prevention strategies. (e.g. use Healthy People 2020, The Guide to Community Preventive Services websites, case studies, peer-reviewed research studies, etc.) d. Why is building community trust critical to improving health outcomes of Native populations.

Prior to the advent of the Affordable Care Act of 2012, signed by President Barack Obama, medication errors cost the U.S. over $200 billion. Medication errors also contributed to gross health disparities primarily impacting elderly populations with co-morbid chronic illnesses. Case Study 20: Big Brother is Watching: Utilizing Clinical Decision Support as a Tool to Limit Adverse Drug Events, provided several examples of how public health and healthcare systems worked together to overcome problems with medication adherence, to improve patient health outcomes and to improve prescribing practices. Provide an update on the impact of the Affordable Act on Clinical Decision Support specifically relating to medication errors. This means, what advancements have been made since the Act to improve Clinical Decision Support in Healthcare or Prescribing. Use the internet and other resources such as the Agency for Healthcare Quality and Research (AHRQ) to briefly summarize your findings. It may also be helpful to cite important resources (i.e. websites or research articles) that support your understanding of the issue. Furthermore, report on what is the current hot topic issue on clinical decision support (e.g. a new policy, advisory group). Check White House resources or the American Public Health Association for clues.

Case Study 16: Beyond Measurement? Evaluating Environmental Public Health: Assessing the Effectiveness of Food Safety Programs, discusses the pressures that many governmental public health practitioners face at the nexus of budget cuts and protecting the health and safety of the population. Please answer the following questions:

a. What sort of roles and responsibilities do environmental health professionals have regarding food safety?

b. What type of information would the environmental health director need to know to help make the case to state legislature to not cut the budget?

c. From the farm to the plate, what are some of the ways food can become contaminated with pathogens?

d. What food safety practices would a health inspector look for doing a routine restaurant inspection?

e. What are examples of recent food-borne illness outbreaks that have taken place in the last 2 years? What was the cause of the outbreak?

f. What actions can health inspectors take to mitigate or prevent an outbreak from occurring?

g. How has COVID-19 impacted food safety, if at all?

h. What is your position?  If faced with cutting the budget or limiting the scope of the environmental health dept. What you would do?  Provide a brief rationale.

Part A. Metatherian Mammals

 

Part A Question1) What are metatherian mammals? What are distinguishing characteristics of metatherian mammals?

Extinct mammals, they are very few living. Metatherians, which comprise marsupials and their closest fossil relatives, were one of the most dominant clades of mammals during the Cretaceous and are the most diverse clade of living mammals after Placentalia. The only living metatherian mammals are the marsupials. There were some extinct metatherians that were not marsupials, such as the Sparassodonts, but as these have gone extinct, a metatherian is now just a synonym for a marsupial Metatherians belong to a subgroup of the northern tribosphenic mammal clade or Boreosphenida. They differ from all other mammals in certain morphologies like their dental formula, which includes about five upper and four lower incisors, a canine, three premolars, and four molar. In metatherians, marsupium is present which is required for carrying the infants

Part A Question2) Describe the biogeography of metatherian mammals.

Part A Question3) Using the following websites choose one extant (currently living) metatherian (marsupial) mammal species. Conduct research about the species. Discuss and analyze the species’ anatomy, ecology, and life history. Write a species account of at least 300 words correctly citing the reference source(s) you used. Scientific names are comprised of the genus (capitalized) followed by the species name (not capitalized) and they are italicized. For example, Ornithorhynchus anatinus.

BI101 Unit 2 Experiment

  • Read through the introductory materials below.
  • Open the Unit 2 Experiment Answer Sheet and complete the following Experiment exercises this unit:
    • Experiment 2 Exercise 1A – Effect of substrate concentration on enzyme function (~30 min)
    • Experiment 2 Exercise 1B – Effect of pH on enzyme function (~30 min)
    • Experiment 2 Exercise 2 – Cellular Respiration and Photosynthesis (~1.5 hrs)
  • Save your completed Unit 2 Experiment Answer Sheet and submit it by Midnight Sunday (CT).

Enzymes – Introduction

This unit we will examine enzyme function using a virtual simulation. Be sure to review our online lecture on Energetics and pp 80 – 82 in your book. As we have learned this unit, enzymes are biological catalysts that can lower the activation energy required to allow reactions to proceed. Enzymes are very sensitive to the environment in which they work, meaning changes in substrate concentration, temperature, pH, salts and other chemicals can drastically alter their function. This is one of the reasons the buffers we learned about last unit are so important!

When you are ready to begin these two exercises, go to:

Bioman. No date. Enzymatic (Links to an external site.)

Procedure

  1. Click on “Start a New Game” and follow the on-screen instructions.
  2. When you get to the “Main Menu”, click on “Experiments”.  You will have to click twice.
  3. Click “OK” and follow the on-screen instructions.  Please note that you do not need to submit the answers from the quiz.

You will need an understanding of the different types of experimental variables in order to correctly graph your results. There are three different types of variables:

Independent Variable: This is the variable that the experimenter manipulates and is expected to affect the dependent variable. For example, if you think the amount of sunlight affects plant growth, you would vary the amount of light a plant receives (e.g., 2 hrs/day, 4hrs/day, 6 hrs/day). The amount of sunlight would be the independent variable.

Dependent Variable: This variable is expected to vary depending on the independent variable. In the example above, plant growth would be the dependent variable, because it is dependent on the amount of sunlight it receives.

Control Variable: This type of variable includes factors (there may be many) that could affect the outcome of your experiment. By holding these variables constant in all treatments, the experimenter knows that only the independent variable is affecting the outcome. In the example above, the variables you would want to hold constant would be things such as temperature, water and nutrients.

When graphing your results, the two variables of interest are the independent and dependent variables. The independent variable is always graphed on the x-axis and the dependent variable is always graphed on the y-axis. When you generate a graph, you must also always label each axis and include any units of measure.

When you are ready to begin, use the instructions in the Unit 2 Experiment Answer Sheet to complete these exercises.

Cellular Respiration and Photosynthesis – Introduction

In this exercise, you will have the opportunity to explore the relationship between the air we breathe and the plants around us. Be sure to review our online lecture on Energetics and Chapters 6 and 7 in your book; particularly pp 92-93.

Cellular respiration is the metabolic pathway in which all plants and animals extract usable energy (ATP) from foods either eaten (animals) or synthesized (plants). Yes, plants perform cellular respiration! This is because the energy they generate via photosynthesis is used to produce sugars. It is these sugars that are then broken down by cellular respiration to provide the energy to carry out plant cellular functions, just like in animal cells!

Cellular respiration and photosynthesis are linked by their reactants and products. Here is a chemical summary of the two reactions:

Cellular Respiration:     Oxygen + Glucose » Energy + Carbon dioxide + Water

Photosynthesis:             Energy + Water + Carbon dioxide » Glucose + Oxygen

What do you notice about the reactants and products of these two processes? RIGHT! The reactants of cellular respiration are the products of photosynthesis and the products of cellular respiration are the reactants of photosynthesis. Without photosynthesis and the production of oxygen, aerobic cellular respiration could not occur. And, carbon dioxide levels would increase significantly!

In this exercise, you will demonstrate this relationship between these two important processes using snails and Elodea, a water plant. When you are ready to start this exercise, go to:

Virtual Labs Simulation
http://www.classzone.com/cz/books/bio_09/resources/htmls/virtual_labs/virtualLabs.html (Links to an external site.)

If a link to Carbon Transfer through Snails and Elodea is not directly available, then follow these instructions:

  • Select Missouri as your location and click Go
  • Click on the Go beneath Biology 2010
  • Under the Labs heading, click on Virtual Labs
  • Click on Carbon Transfer through Snails and Elodea

You will need to open the Unit 2 Experiment Answer Sheet and follow the instructions carefully. The simulation is a little clunky to use and if you don’t do things right, you will have to start over. You must complete certain steps before you can proceed.

Biol 1408

This discussion has 2 parts that should total 200 words in 2 paragraphs. In Part 1, answer the questions in paragraph form using about 100 words. In part 2, read the prompt and discuss your thoughts in an additional 100 words. Once you have submitted your initial post, return to read the posts of others.

1. Observe an ice cube or hold one in your hand.  This is water in a solid form, so it has a high structural order.  This means that the molecules cannot move very much and are in a fixed position.  The temperature of the ice is zero degrees celcius.  As a result, the entropy of the system is low.

2. Allow the ice to melt at room temperature.  What is the state of molecules in the liquid water now?  How did the energy transfer take place?  Is the entropy of the system higher or lower?  Why?

3. If you were to heat the melted water to its boiling point, what would happen to the entropy of the system?

Part 2:

Think about the world around you. Give another every day example of entropy and explain how it relates to increasing disorder of energy. If all energy tends to become more disordered, how do we always have a supply of usable energy?

Microbiology

SUMMARY

Many interventions, protocols, and prevention methods are used to maintain or improve overall human health. The aim of some is to improve quality of life, while others specifically reduce, remove, or eradicate microbial pathogens which would otherwise cause disease.

Many such processes may also result in, or cause, unintended consequences to humans, pathogens, and/or the environment that were not predicted. The most well-known example is that of the rise of multiple antibiotic resistant bacteria following the use (and overuse) of antibiotics.

Each of the papers in this discussion provides an example of interventions originally intended to improve health and prevent disease. The first paper by Alharbi et al concerns restroom electric hand dryers. The second by Nettleton et al discusses artificial sweeteners and their impact on the gut bacteria. The third is a review of the latest findings that trehalose, an artificial sweetener, may have contributed to the current disease epidemic of Clostridium difficile. Finally, McNamara and Levy discuss the current status of triclosan which was first introduced in the 1970s. A background paper which defines and reviews the Hygiene Hypothesis, by Roduit et al, is also provided.

DISCUSSION PROMPTS

· What was the specific original intent of the intervention or procedure described in each of the papers and what was their unintended consequence(s)?

· Can you offer a solution or remediation for any or all of the resulting consequences from these interventions?

· What is the Hygiene Hypothesis (described in the Roduit paper) and how is it related to this discussion?

· Follow the APA format

· 1.5 page paper

Bioregional Portrait

Bioregional Portrait: (50 pts. possible) The following assignment was modified from one that was developed by the Biology Faculty at BC, and derived from the Bio 100 Student Module. One of your major writing assignments in Biology 100 is a “Portrait of your Bioregion”. There are a number of questions asking you to research your own personal environment and your place as part of that ecosystem. We define your home place as your watershed, ie. giving it biological rather than political boundaries. Nature does not recognize human made boundaries which are often lines drawn arbitrarily on a map. Nature’s boundaries are rivers, oceans, lakes, and mountains. Your watershed is all the area drained by a stream, river or lake – literally from where the water is shed or flows.

All too often we concentrate on far away, exotic, ecosystems like tropical rainforests and forget that we, too, live in a unique biome – the temperate rain forest. This assignment is asking you to explore your particular part of that biome up close and personal.

One of the objectives of this assignment is to help you better understand and appreciate the ecosystem in which you live. Part of the injunction to “Think globally, act locally” implies a knowledge of our local environment. Another objective is to ask you to think about the size of your own ecological footprint. How lightly do you step upon the land? Do you know how you use natural resources and are you using them wisely?

For this assignment think in terms of providing a stranger a unique picture or snap shot of your own personal environment and how you interact with it. Tell that person what you observe from where you live, not what you can read on the Web or hear from city officials. Everybody will have a different picture even if they are neighbors. Even identical twins living in the same house will present different portraits because they are looking through different eyes.

You can call local government offices, utility companies, etc. for further information. Mostly, though, we want to go outside around your home and observe what else shares your space. Don’t look up in a book for your trees and birds – go outside and look at them.

Think about how the land forms around you were made and how humans and other animals have shaped those land forms. In terms of European settlement the history of the Seattle area is quite short, but humans have lived in this area for at least 12,000 years.

Portrait of your Bioregion – For this assignment you need to answer ALL of the following questions about your local ecosystem. Your answers should be as complete as possible, with citations from where your information comes from.  Feel free to include drawings, photos, etc. answer the following questions in detail to describe your Bioregion. I’ve provided some hints inblue.

  1. Describe exactly where you live. Draw a map if you like. This should not include your address, describe where you live in terms of the geography without any man made points of reference.
  2. What is a watershed? In which watershed do you live? This means your own personal watershed according to the biological definition – do not ask the local water utilities for the name of your watershed. Here is a site that will also help identify your watershed. The more specific you can be the better.(Links to an external site.)
  3. Name five trees in your area, (within one or two blocks of your house). Which ones are native? This site might be helpful.
  4. Name five resident plus any three migratory birds in your area.
  5. Where is your local water supply stored? Look around your neighborhood for the nearest water tower or reservoir.
  6. Where does your wastewater go and what happens to it along the way? When you flush your toilet what happens to it? Where are the pollutants removed? Is primary, or secondary, or tertiary treatment done there?
  7. You’ve changed the oil in your car and now you need to get rid of the old oil. How do you do that in a way that is safe and environmentally sound? Be specific in your answer, where exactly would you take it.
  8. What was the area you live in like 50 years ago? 100 years ago? 200 years ago? Include people, places and nature in your description. What what was happening to the Indigenous Peoples of your Bioregion during each time period? The History Link is a helpful resource at:http://www.historylink.org (Links to an external site.)
  9. Name some animals (non human) which share your place. Include both wild and domestic beings.
  10. What type of energy do you use to heat your house, from where does this energy come? What environmental effects does this type of energy have? All forms of energy have negative environmental effects, figure out what you use first.
  11. Name the nearest creek or stream to your home, and trace its passage from source to outlet. Include above and below ground portions. Google maps can be helpful here or a topo map.
  12. List the nearest local, and state, and national park to your house, what kinds of activities are allowed in each of these (hunting, fishing, camping, motorcycling, horseback riding etc.)

Points will be assigned for depth and breadth of information and for creativity in presenting the information. Create a picture of your own Bioregion so that others can see the value and complexity of your environment.

Include with your answers a list of references to indicate where you obtained your information. Use the format in the MLA guidelines to construct a bibliography for the references that you use on each question. After you have assembled your bibliography, make sure your citations are formatted correctly. Do not use footnotes or citations of any kind within the body of this assignment. The LMC Librarian Instructions for  MLA Bibliographies are found at: at: http://www.questionpoint.org/crs/servlet/org.oclc.admin.BuildForm?&page=frame&institution=13150&type=2&language=1

Skeletal System

  Experiment 11: Skeletal System of the Fetal Pig

In this exercise you will become familiar with the skeletal system of the fetal pig. Because the fetal pig had not reached its full gestation, many of the bones have not fully developed, but are instead still cartilaginous. Still, we can look at this structures to gain a better understanding of the axial and appendicular skeletons, along with the joints.

 
  Materials

Fetal Pig Dissection Tray

Dissection Tools Kit String (should still be tied onto pig’s hooves)  
       

Procedure

1. To begin, lay your underpad down and place your dissecting tray on top of it. Lay out your dissecting tools. Be sure you have all of your safety equipment on before beginning the experiment.

2. Once prepared, gently open the bag your pig is in. Note: DO NOT destroy this bag or empty out the preserving solution within the bag, you will need it for the whole semester.

3. Lay your pig into the dissecting tray, dorsal side facing up. Slide the strings over the dissection tray to hold the pig in place.

4. Look at Figure 21 displaying the skeletal system of a grown pig. Notice the similarities and differences between that of your human skeleton and that of the pig.

5.
Figure 21:  The pig skeleton

6. Due to the rigidity of your pig, it typically will not stay in this position on its own so you will need to hold it while you examine the skeletal system.

7. Begin by examining, through the skin, the axial skeleton as shown in Figure 21. Feel the bones of the skull, then continue down the vertebral column feeling the vertebrae along the way. Notice that the tail of the pig is composed of caudal vertebrae. Note your observations in Table 34.

8. Slide the strings off of the dissection tray and gently turn your pig ventral side up. Slide the strings back under the dissection tray after the pig is correctly positioned.

9. Feel the thoracic cage of the pig. Though you will not cut into the pig today, feel the similarities that occur between the fetal pig and the human skeleton model. Note your observations in Table 34.

10. Turn your attention to the appendicular skeleton. The pig’s four appendages correlate to the human arms and legs. Use Figure 21 as a guide to try and feel the different bones of the arms and legs (humerus, femur, tibia, etc.). Note your observations in Table 34.

11. In Figure 21, look at the pelvic girdle of the pig. This structure appears noticeably different than that of a human. However, the innominate bones of the pig are created by the ilium, ischium and pubis.

12. Focus your attention on the joints of the pig. The pig should be fairly rigid due to the preservation fluids. However, you should still attempt to produce the movements created by synovial joints on the pig (e.g., flexion, rotation, etc.). Notice the joints at which these movements are possible. Do they correlate to human movement? Note your observations in Table 34.

13. Take a photograph of your pig in the dissection tray for the upload document. Make sure that your name is written on a piece of paper that is clearly visible in the background of the photograph.

14. You are now finished with the external observations of the skeletal system. Remember that as you dissect into your pig, you will be able to touch and feel the bones of the skeletal system. As the dissection progresses, always take note of the bones present within the fetal pig.

15. To finish, locate the bag the pig came in. Gently place the pig back into the bag and tightly secure the bag with a rubber band, or place in the zip-seal bag provided in the dissection box.

16. Place the pig back into the cool environment you had previously stored it in. Remember, the best place to keep the pig is in a cool, dark place.

17. After your pig has been put away, clean off your dissecting tray and dissection tools with soap and water. There should not be any biological scraps because you did not cut into the pig. However, biological scraps should not be thrown into the garbage.

18. Clean the area in which you worked with soap and water as well. As long as the underpad has not been damaged, keep it for future experiments.
