The idea of Paleolithic humans giving a tangible visible representation to intangible symbolic imagery they were “seeing” in their heads through altered states of consciousness (visions, dreams, hallucinations, trance). We have a better understanding of our brain’s visual mechanics in our own time but we as humans still routinely tap into altered states of consciousness, whether it’s through daydreaming, roleplaying (ex. Cosplay) meditation, dance, substance use, or escapism into virtual worlds such as video games, movies, music, art, social media.

-WHAT, IN YOUR OPINION, IS THE APPEAL OF AN ALTERED STATE OF CONSCIOUSNESS FOR US AS HUMANS?

-If you find yourself wanting to “unplug” from reality in an altered state, what feeling are you after and is there a visual component to it?

-How can we relate our own state of altered consciousness in modern times, back to the Paleolithic humans and their interest in recording visions they saw in their heads on the walls of caves?

1. Consider a convex lens with a focal length of 5.50 cm. An object is located at 13.50 cm. The object is 6.00 cm tall. Draw the ray diagram to scale. Determine the image distance, the height of the image, the magnification and the characteristices of the image. Pay attention to the sign conventions and units.

2. White light shines through a diffraction grating with 7300 lines per cm. Make a table of diffraction angles for m = 1, 2, 3, ... versus the wavelengths of red and blue light. Stop when the angle is undefined. Note there may be more starts than finishes. Based on your table: How many complete diffraction patterns are there? What is the wavelength of the light diffracted at 90 degrees for the highest order incomplete diffraction pattern? Remember that the wavelength range of visible light is from 400 nm (blue) to 700 nm (red).

Case Scenario

Your favorite seventy-two-year-old Uncle Bob recently slipped on the ice and broke his left hip. After surgery and a four-day hospital stay, the hospital is ready to discharge him. His physician believes Uncle Bob would benefit from a stay at a skilled nursing facility where he would receive skilled nursing, physical therapy and occupational therapy. The physician writes the order. Your Uncle Bob has Medicare A and Medicare B.

Questions

1. Will Medicare cover his skilled nursing facility stay?Why or Why not? Be specific.

Because the social workers cannot recommend a facility, Uncle Bob asks you, the future healthcare administrator, for your advice. He wants to stay in within 10 miles of the State College area so family and friends can visit during his stay.

2. Using the data compiled in Nursing Home Compare (Links to an external site.)Links to an external site., which facility do you recommend and why?

Compare facility information to state and national standards, speaking specifically to (a) health inspections, (b) quality and (c) staffing in your response.

3. Based on your assessment of the facility data, is the Five-Star Quality Rating System helpful to potential residents and their families in making decisions about nursing home care?

Why or why not?

4. If a facility receives a five-star rating in one period and then is downgraded to a lower rating in a later period, does it face any financial consequences? Explain.

Hyperkalemic Periodic Paralysis (HPP) is a condition that produces periods of muscle weakness or paralysis. Despite its name (hyperkalemia means elevated K⁺), HPP is the result of a genetic mutation in voltage-gated sodium channels. Animals with HPP (horses get it, too) have a mutation in the gene that encodes the inactivation gate for voltage-gated Na+ channels.

a. For a normal action potential, please list the stages of the action potential, including the state of the gates AND the channel for BOTH the voltage-gated K+ AND Na+ channels. Use the following to guide your answers:

b. The mutation in the voltage-gated Na+ channel allows the channel to recover from inactivation sooner than normal. You are working with cells expressing this mutation. What would happen to the ability of these neurons to generate action potentials? Would they generate more, fewer or the same number as a wild-type neuron? Explain, based on your understanding of voltage-gated channels that underlie the action potential, why this is the case.

Section D – BCNF Decomposition

For each question in this section, you are required to decompose the given relation into BCNF form
and state any new relations created in the process with their functional dependencies and identify any
functional dependencies which are lost during the decomposition. You must show your working using
the tree method presented in tutorials. Consider the functional dependencies in the order presented
in the question.

Question 1
R [A, B, C, D, E, F, G, H, I, J]
{A} -> {B, C}
{B} -> {D, E, F}
{C} -> {G, H, I}
{H, I} -> {F, J}

Question 2
R [A, B, C, D, E, F, G, H]
{A, B, C} -> {D, E, F, G}
{G, H} -> {A, B, C}
{C} -> {H}

Section E – 3NF Decomposition
Question 1
Based on the following relational schema and functional dependencies, find minimal cover for
relation R.
R [A, B, C, D, E, F, G, H, I, J, K, L, M, N]
{A} -> {C, D, F, G}
{B} -> {E}
{A, G} -> {J, C}
{D, E, B} -> {H, I, J}
{J} -> {K, L, M}
{M} -> {N}

Question 2
The minimal cover has been provided below for a given relation with a set of functional
dependencies. Using the minimal cover, normalise the relation to 3NF such that all functional
dependencies are preserved.

R [A, B, C, D, E, F, G, H]
{A} -> {D, F}
{B} -> {G, E}
{F, G} -> {H}
Minimal Cover: {
{A} -> {D}, {B} -> {G}, {B} -> {E}, {A} -> {F}, {F, G} -> {H}
}

The 2002 SOX Act required integrated audits for all public companies with immediate implementation by larger accelerated-filers.  The 2010 Dodd-Frank Act modified section 404 of the SOX Act to exempt certain smaller companies (non-accelerated-filers) from having external audits of their ICFR.

Given the importance and function of internal controls and known fraudulent activities, do you agree with this modification that eliminated the need for these smaller public companies from having auditor’s express an opinion on their ICFR? Explain your answer.

Though recommended, there is no requirement for private and not-for-profit companies to have external auditors audit their ICFR. Explain whether you feel these organizations should have their ICFR audited by external auditors.
