Discussion 10 – Controversy 10: Ergogenic Aids: Breakthroughs, Gimmicks, or Dangers? Using the information found at the end of Chapter 10 about the Controversy: Ergogenic Aids: Breakthroughs, Gimmicks, or Dangers? Read first the content in the book, supplement the reading with the power point that emphasizes the main points of the controversy. Then, write a 200-250 word response of the controversy. As the book reads, “Athletes can be sitting ducks for quacks. Many are willing to try almost anything that is sold with promises of producing a winning edge or improved appearance, so long as they perceive it to be safe. Stores (on site or Internet) advertise several products that offer better performance, more muscle mass, etc., and among these products the most common include; protein powders, caffeine pills, steroid replacers, amino acid supplements, etc. – we will start with the story (found in the book) of Paige and DJ, who are college roommates, and who had experienced the famous “freshman 15,” and now they are planning to start exercising to lose of some extra-weight, and at the same time, to look good. In this context, while preparing the response keep in mind the following: 1. To increase muscle performance, Paige decides to use Carnitine, and protein powders. Discuss why Paige’s use of carnitine and protein powders will not give her an advantage in terms of muscle performance as compared with DJ’s more adequate diet and regular exercise. 2. Question #1 focused on Paige, and DJ; who are not collegiate athletes, now, think in terms of those college students who are on collegiate athletic teams. Why are amino acid supplements not recommended for athletes? 3. With the idea to improve performance some athletes use anabolic steroids, but why might the use of anabolic steroids actually work against the athlete in terms of enhancing performance? 4. Another common practice for student’s athletes is to take antioxidant supplements, but why do athletes take antioxidant supplements, and what concerns do experts have about them? 5. Application: please share how you think you will be applying the concepts learned in this controversy in your life, and/or, in the life of people that are closer to you; or, maybe in your job.

This week we started learning about evolution. There are several examples in the text about organisms that have evolved. Evolution is fraught with emotion and it can be difficult to discern between fact and opinion. For this week’s discussion, find two articles on evolution, one scientific from a credible source, and one from a questionable source. Please provide links in your post.  Please answer these questions and label 1-4 1.  Which article in your opinion was of more scientific merit? Why?  Be sure to use concrete examples from the articles to support your claims. 2.  Which article was more interesting and captured your attention?  Why?  Again, be sure to use concrete examples from the articles to support your claims. 3.  How do you know which article has information that is correct and based on fact rather than opinion or mis-information? 4.  A compelling argument can sometimes lack scientific merit, what are some strategies you can employ to avoid being “taken in” by a compelling, but not accurate argument? How do you KNOW what you’re reading is true?

In this assignment, you will focus on the impact of COVID-19 on the selected operation. You will critically discuss the operation’s response to the global pandemic and focus on, at least, one aspect of the operation’s design and/or planning and control. Respond to the follow comments and questions with the attached document. Operations Performance using academic models: discuss operations improvement after, and before COVID-19 pandemic. What tools (6 Sigma, Lean, ishikawa, FMEA,  perhaps) do you employ to help you make decisions? I.e. for Problem solving, continuous improvement. What kind of key performance indicators do you monitor and what tools do you use to report them? I.e. control charts, polar diagrams, etc…Can you provide a snapshot of your kpi dashboard? In terms of resources management, has Covid altered performance measurement within your organization? Operations Design and Planning and Control: Focus on:  at least one element of operation design and planning and control to explain how the company has adjusted its operation to deal with the implications of COVID-19 pandemic. The elements of operations planning and control may include inventory management, capacity and demand management, materials planning, Enterprise Resource Planning (ERP), MRP, and supply chain management.  In light of your discussion of the operations strategy, critically assess the different design and planning and control elements of the selected operation. In light of the operational framework, how has the shift in productivity requirements help you modify the current operational design? Has Covid 19 warranted the implementation of a new design?

Bones are the individual organs that make up the skeletal system, and muscles are the organs that hold those bones, and us, upright and together. There are 206 bones in the adult skeleton, and more than 700 muscles in the human body. For the Unit 3 discussion, think about a particular bone or muscle in the human body. What is its structure? How does its structure allow the body to do a particular thing? For example, how does the structure of our arm bones allow us to do handstands? Are there any muscles involved? What do they do?

Part 1: For this project, you will be gathering information on your chosen primates and doing three, 20-minute primate observations. You will use the same group of animals for each observation. You need to observe for 20 minutes at 3 different times of the day and one of those observations needs to be feeding. This means you will need to make several short observations to determine when feeding occurs. In order for your observations to be fruitful, you need to observe when activity is taking place. So you will need to check in on the webcams often to see what is going on. Observations of chimps sleeping or empty observation areas are not useful and can not be used. I have included an excel spreadsheet for you to record your information. Once you have completed your observations make sure you upload your spreadsheet in the answer area. Primate Observation Worksheet Resources: Some of these resources may not be available. Primate Info Net Ape Cam San Diego Zoo Chimpanzee Window Cam Houston Zoo Gorilla Cam Houston Zoo Snow Monkey Cam KC Zoo Cam Any other that you may find – make sure you add it to your observation sheet What you need to do: Make your observations Fill out your spreadsheet. There are two pages make sure you gather the classification, morphology and locomotion information on your primates on sheet 1. You can use Primate Info Net (also listed above) to help you. Post your spreadsheet Part Two: Write a summary of your observations. This summary is posted with your spreadsheet – in the same post. When writing your summary consider the following: Mother/infant activities. How the design of the exhibit affects social behavior. Grooming cluster (a group of females that groom one another) Play activities engaged in by young animals that teach them skills necessary for adult survival) Playgroup (age-mates that play together) Threat gesture (an action that shows aggression but stops short of a physical attack) Presenting (the act in which a submissive individual positions the anal region toward a dominant individual). Dominance (where one animal displaces another and takes preference over food, sexual access, etc.). Submission (where one animal moves away from or gives up food or space to a dominant animal). Mounting (where a dominant animal mounts a subordinate one). Call (usually a short simple vocalization that transmits a message such as danger). Yawn (not necessarily an expression of boredom, may also be a display of large projecting canines in a threat gesture.) Stare (a simple stare can act as a threat gesture). Lip-smacking (animal opens and closes its lips rapidly with the tongue darting in and out, used as an appeasement gesture by a subordinate animal and can also occur during grooming.) Types of grooming: auto grooming (grooming oneself) allogrooming (grooming another animal) Sexual behavior (where an estrus female presents herself to an interested male for the purpose of sexual activity) Part Three: FOCUS ANIMAL Human Primate Find another primate – this time a human. I recommend using a park on a sunny afternoon for this observation. For the next 15 minutes, observe just one human primate’s behavior, noting who it interacts with, etc. After this pick a second focus human primate and observe it for 15 minutes. Note your data on the spreadsheet (Human 1, Human 2). Write up a summary comparing the behaviors of these two human primates animals. Include it as an additional paragraph in Part 2. how do their behaviors express their differences in regards to sex, age, and dominance? how do their behaviors compare with the non-human primates you observed during part 1 of your observation. Draw a conclusion – this conclusion needs to be based on what you observed (not what you think or feel). Use examples from your observation to support your conclusions. Your conclusion should be a separate paragraph and more than one sentence long. Drawing a conclusion is standard for any research paper. PROPER RESEARCH OUTLINE An introductory paragraph – who, what, why, etc. What is the task you are accomplishing (thesis statement). Next comes your data – in our case observations 3 for the non-humans, 2 for the humans – each as a separate paragraph. This should include as much data as possible. Like the time of day, what you were observing, where you were observing and what you observed. Next is a paragraph explaining what you saw – and or comparing what you saw. NOT – what you think or feel but, just what you saw. No assumptions and personal opinions – neither should be in your paper. Next is your conclusion – based on what you observed! If it wasn’t in your observed data – it should not be in your conclusions. Your conclusions should also be supported by examples from your observations. Don’t overthink this. You not going to come up with something stunning or new – at least not at this point. Just stick with your data. CHECKLIST – for posting RUBRIC You did three 20 minute non-primate observations using the live webcam links – use the same cam for each observation. You filled out both pages of your Excell spreadsheet. Classification and observation. You wrote a summary of your observations for the non-human primates You observed two human primates for 15 minutes each and recorded this information on your spreadsheet. You wrote a summary of your observation comparing the two human activities in terms of age, sex, and dominance. You wrote a summary comparing the activities of the non-human primates and the human primates. You uploaded your spreadsheet properly – only xls or xlsx files will be accepted. If you don’t know how to upload your spreadsheet and assignment check out this link. You included your 3 part summary which should be about 1500 words. This is an attachment and must be saved as a word or pdf. zIt should be uploaded at the same time as your spreadsheet and in the same manner using the ADD Another File button – see the link above. If your assignment is incomplete you will not get full credit. You did your own work – this assignment is checked for plagiarism. look at the files for the example

This is for an intro to kinesiology course. The prompt is: What is similar and what is different between the meanings of the terms biomechanics, human movement biomechanics, and kinesiology? What are the goals of the study of biomechanics? What are the primary application areas of biomechanics in kinesiology? This is based off of the information in a standard kinesiology textbook.

The Nobel Lecture Summary & Essay is a required Assignment, and is worth 6% of your final Lecture grade. The Final Draft is due Tuesday, November 3. Check the posted Nobel Lectures (/Course Materials).  Read a complete lecture.  Look up one or two key References, if necessary, to make sure you understand the key hypotheses and Results presented in that particular Nobel Lecture.  Summarize and review the lecture in a 3 – 4 page, single (or 1.15) spaced paper following the same general format as for a Term Paper (Title, Introduction, Individual Topics with subheaders, as appropriate (Note: if lecture chosen “rambles” without pauses or topic sentences, then your summary of same need not have topic headers), Discussion/Conclusions, References). Include some personal comments about how you responded to the author’s presentation (Was it clear? Was the importance of the work obvious? Did the work seem to progress well beyond key original findings that earned the Nobel Prize? Did you learn anything about the author’s way of thinking about and approaching problems?.
