Attachment of myelin to the surface of some neurons occurs via the interactions of transmembrane adhesion molecules expressed on the myelin membrane with receptors on the target axons. Several human peripheral neuropathies are associated with mutations in genes encoding theses myelin-associated proteins that disrupt myelin-axon attachment, (1) Explain the symptoms this loss of peripheral myelination might be expected cause and why, given the function of myelin in the nervous system. (2) Propose a hypothesis to explain why only peripheral and not central nervous system symptoms are observed in these diseases.

When a restaurant employee slipped on spilled soup and fell, requiring the evening off to recover, the owner realized that workplace safety was an issue to which she had not devoted much time. A friend warned the owner that if she started creating a lot of safety rules and procedures, she would lose her focus on customers and might jeopardize the future of the restaurant. The safety problem is beginning to feel like an ethical dilemma. Suggest some ways the restaurant owner might address this dilemma. What aspects of human resource management are involved?

Two cannons are mounted as shown in the drawing and rigged to fire simultaneously. They are used in a circus act in which two clowns serve as human cannonballs. The clowns are fired toward each other and collide at a height of 1.05 m above the muzzles of the cannons. Clown A is launched at θA = 76.0° angle, with a speed v0A = 9.50 m /s. The horizontal separation between the clowns as they leave the cannons is d = 5.55 m. Find the launch speed v0B and the launch angle θB (>45.0°) for clown B. magnitude m/s direction °.

In the one-period model, education can be represented as time spent by the representative consumer that is neither leisure nor time applied to producing output. What the economy gains in the future is that the representative consumer then has more time available, as measured in terms of effective units of labour time (adjusted for skill level, or what economists call human capital). That is, the aggregate production function can be seen as Y=zF(K, eN), where e is the quantity of human capital per worker, and education in the present increases e in the future.
Using the one-period model, what effects does additional education have in the present on consumption, leisure, employment, aggregate output, and the real wage?
consumption _________ (may increase, decrease, or not change, or must decrease, or must not change, or must increase)
Leisure _______ (may increase, decrease, or not change, or must decrease, or must not change, or must increase) and the magnitude of the change in leisure _________ (must be equal to, must be less than, must be greater than, or must be greater than, less than, or equal to) the amount of additional time devoted to education. Employment (measured as hours worked) ________ (may increase, decrease, or not change, or must decrease, or must not change, or must increase) aggregate output _________(may increase, decrease, or not change, or must decrease, or must not change, or must increase) the real wage ________ (may increase, decrease, or not change, or must decrease, or must not change, or must increase)

There are two main ways to describe how loud a sound is. One is that you can describe its intensity, I, measured in W/m2, which is the amount of energy per unit time, per unit area, transported by the sound. However, this is not very close to the human experience of sound loudness. The human experience of loudness (actually like the way most of our senses work) is that each factor of 10 in intensity sounds like the same sized “step” in loudness. In other words, in our experience of sound, the difference between 0.01 W/m2 and 0.1 W/m2, seems the same as the difference between 0.1 W/m2 and 1 W/m2. For this reason, when talking about loudness we often use the “decibel scale”, defined by
?I? β = (10dB)log I0
where I is the sound intensity, I0 is a reference intensity and β is the loudness in decibels. A common choice for I0 is the “threshold of hearing”, which for a typical person is I0 = 1 × 10−12 W/m2.
(a) What intensity corresponds to β = 0 dB? Does 0 dB mean “no sound”?
(b) The “threshold of pain” (hopefully the name makes it clear what this means...) is 130 dB. What sound intensity
does this correspond to?
(c) Some sound has a loudness of 50 dB. Another sound has 1200 times the intensity of the first sound. What is the loudness of the second sound?

Rossi Industries has payroll processes as described in the following paragraphs:
When a new employee is hired, the human resources department completes a personnel action form and forwards it to the payroll department. The form contains information such as pay rate, number of exemptions for tax purposes, and the type and amount of payroll deductions. When an employee is terminated or voluntarily separates from Rossi, the human resources department completes a personnel action form to indicate separation and forwards it to the payroll department.
Each employee in the production department maintains his own time card weekly. Employees fill out their time cards in ink each day, and at the end of the week, the time cards are forwarded to the payroll department. Employees in the payroll department use the time cards and employee records to prepare a weekly paycheck for each employee who has turned in a time card. A copy of the payroll checks is forwarded to the accounts payable department, and the original payroll checks are forwarded to the cash disbursements department to be signed. The payroll department updates the payroll subsidiary ledger. After the paychecks are signed, they are given to department supervisors to distribute. Any unclaimed checks are returned to the payroll department.
Required:
a. Prepare a process map of the payroll processes at Rossi.
b. Identify both internal control strengths and internal control weaknesses of the payroll processes.
c. For any internal control weaknesses, describe suggested improvements.
