Part B

2. In each of the following, indicate whether the result or relationship is likely to be practically significant and then explain your reasoning:

(a) A researcher finds that a particular relationship can occur by chance about 20 times in 100

(b) A researcher finds that students who use a new biology textbook recently purchased by the school district scored an average of 20 percent higher on an end-of-the course examination

(c) A researcher finds that use of a certain drug decreases the incidence of a life-threatening illness among a group of senior citizens by 3 percent

(d) A small appliance store owner finds that advertising in the local neighborhood newspaper increases her sales each week by 1 percent

(e) A new method of teaching five-year olds how to tie their shoes results in their being able to do so three weeks earlier than similar five-year olds not taught by this method

(f) A researcher finds that a correlation of .18 has only a 1 in 1,000 likelihood of occurring by chance

An elephant has an aorta that is approximately 8 cm in diameter and a resting heartbeat of 35 beats/min. Over the cardiac cycle, do you think that velocity profiles in the aorta will be:

 fairly flat, oscillating back and forth, or

 more parabolic, oscillating back and forth?

Make and state necessary assumptions.

Blood flows in a tube of radius 1 cm because of a pressure gradient of 0.4 dynes/cm³. Treating the blood as a Casson fluid with yield stress 0.06 dynes/cm², what percentage of the total volume flow rate is from blood traveling in the central non-flowing “core” of the flow?

The binding strength of a single αIIbβ3 integrin complex to fibrinogen has been measured to be 60 to 150 p N [37]. Suppose that a value of 100 p N is typical for all integrins. How many integrin complexes would be required to maintain adherence of a vascular endothelial cell to the wall of an 8 mm diameter artery carrying 1.4 l/min of blood? You may treat the blood flow as steady, take blood viscosity as 3.5 cP, and assume that the apical surface area of a single endothelial cell is 550 μm².

In the nineteenth century, Poiseuille’s law was experimentally deduced by J. L. M. Poiseuille, who was interested in understanding the flow of blood in horses’ arteries. We now know that Poiseuille’s law is a poor way of modeling blood flow in arteries. In your own words, give at least three reasons why Poiseuille’s law is not appropriate for arterial blood flow modeling, and briefly discuss why this is the case.

Write a short essay (about 300–500 words) on a eukaryotic cellular organelle of your choice, describing its structure, function, etc. (This may require a quick trip to the library; a good place to look would be under cell biology in the QH 581 section of your Science and Medicine library).

 the necessary forms and creates a medical record. Patients are seen by the physician in the order they arrive. If one of the two examination rooms are empty, the nurse escorts the patient to the examination room and records the complaint. The nurse performs routine tests. The nurse writes the complaint and findings on a medical examination form, a form that will be subsequently filed with the patient’s medical record. The physician examines the patient and orders medical tests, if necessary. A diagnosis and treatment plan are presented to the patient by the physician; a written copy of this plan and any other appropriate instructions. [Notes are written on the medical examination form.] When the physician releases the patient, the patient returns to the receptionist, who prepares a bill. If the patient has health insurance, the bill is sent to the health insurance carrier. The patient leaves after either paying the bill (by cash, check, or credit card) or signing the forms to authorize payment by his or her health insurance company. If the health insurance company refuses to pay or partially pays the bill, the receptionist bills the patient by mail. Any patient with an unpaid bill or bad credit history is refused subsequent treatment until the old bill is paid.

o Chapter 4: Exercise 4-1 through 4-4 (page 72 of the text)

EXERCISES

· 4-1 You decide to invest $100,000 in a program that is guaranteed to grow by 2.5% for each of the next 5 years. At the end of the 5 years, how much is your investment worth?

· 4-2 What is the effective annual rate of an investment that pays 6% for 5 years, compounded semiannually?

· 4-3 What is the present value of a single cash flow of $25,000 received at the end of 10 years, if we assume a discount rate of 5% annually? With a discount rate of 7%?

· 4-4 Suppose you deposit $100 in a savings account that compounds annually at 2%. After 1 year at this rate, the bank changes its rate of compounding to 1.5% annually. Assuming the compounding rate does not change for 4 additional years, how much will your account be worth at the end of the 5-year period?

AUT527 W6 SQs – Temple Grandin Movie

1.  Is this a realistic depiction of autism?   Why or why not? To what extent does the level of achievement of Temple Grandin represent the opportunities often achieved by individuals on the spectrum?
2.  What elements of the symptoms of autism were accurately portrayed? Be explicit across the triad of symptoms –communication, social, and behavioral symptoms.
3.  What were the most uniquely acted elements of autism? Did the actress accurately portray what one might see in an individual with autism. Be specific across the triad of symptoms.
4.  How did the movie most effectively convey the struggles experienced by the individual with autism? By their family?
5.  What did the movie suggest as the top factors related to Temple Grandin’s success?
6.  What are the strengths of the movie?
7.  What does it do to advance the public’s understanding of autism and of autism treatment?
8.  Are there any liabilities, areas of concern in the message of this movie? Are there any points made that you think could lead viewers to misunderstand autism?
9.  Do you think the viewer would walk away with any sense of effective treatment? Explain why or why not
10.  Do you think the viewer would walk away with an understanding of the range of symptoms, challenges, strengths, and outcomes that we see in individuals with autism? Why or why not?

Rain man

1. Comment on another depiction of autism in the movies (e.g., Rain Man). Comment on how this depiction might contribute similarly or differently to public perception and understanding.
