...Pivotal Moments Amy Conlin Phoenix Community College April 20, 2015 1 What makes us leaders as we enter the working force? Many of our leadership traits are already innately instilled it is now up to ourselves to expose, grow, and maintain nursing. Many leadership styles are outlined this does not mean we can not brake the mold. This simply means for us to be a leader to our peers, new upcoming nurses and help grow for the better of our patients. Our patients is and will remain the number one reason all of us indulged into the nursing profession. Leadership style that is most appealing is that of authoritarian. This does not mean any superiority but for the greater good in our patients. It is important that we put our patients before social status. We must maintain health satisfaction to those we serve daily. Authoritarian leaders uphold stringent control over our patients by directly regulating rules, methodologies, and actions. Nursing leaves little room for error and we must lead by example. We make goals and see to it that these goals are made. Whether this be interdependent our as a group. Rheba de Tornyay was a very successful leader. She grew up on a small chicken farm in northern California, during the depression. She knew from a young tinder age that she must make something of herself. She grew up in a low to medium class so she knew she had little room for error. She attended college prematurely and with failing...

Total cost TC = cf + v*cv TC= 55000+ 10000*8 TC= $135000 Total revenue TR= v*p TR= 10000*21 TR=$ 21000 Profit Profit= TR-TC Profit= TR-TC P= 21000-135000 P= $ -114 000 b.Break even volume, V= cf/ (p- cv) V= 55000/ (21- 8) V= 4230.77 recap tires, 2. monthly break even volume V= cf/ (p- cv) We have Cf= 30000, cv= 0.16, p= 0.40 V= 30000/ (0.4- 0.16) V= 125000 units 3. If the new price is p= 0.60, Then the break even volume will decrease. We don’t need to sell as much units as before to break even. Proof: V= 30000/ (0.6- 0.16) V= 68181.81 units 4. If we increase advertising, that means CF increases, then the Break even volume will increase, because the cost of the production increased. Proof; V= 30000+ 14000/ (0.6- 0.16) V= 100000 units 5.we have Cf= 5600, cv= 0.35, p= ?; v= 2000 (note: Cf= 2500+3100; Cf= $5600) a.What price should be charged to break even? Break even means Profit = 0, then TR=TC Meaning V*P= cf+ V*cv, then P= (cf+ V*cv)/ V P= (5600+ 2000*0.35)/ 2000 P= $3.15 b. If during the season, there are less guest than expected, to break even, she needs to increase the prices. 6. we have Cf= 360000, cv= 12000, p= 17000; a. determine V , V= cf/ (p-...

...content and the hum of the threshing machine sounding from the farm. "What did I come in here for? What did I want to find?" My hands were empty. "Perhaps its upstairs then?" The apples were in the loft. And so down again, the garden still as ever, only the book had slipped into the grass. But they had found it in the drawing room. Not that one could ever see them. The windowpanes reflected apples, reflected roses; all the leaves were green in the glass. If they moved in the drawing room, the apple only turned its yellow side. Yet, the moment after, if the door was opened, spread about the floor, hung upon the walls, pendant from the ceiling--what? My hands were empty. The shadow of a thrush crossed the carpet; from the deepest wells of silence the wood pigeon drew its bubble of sound. "Safe, safe, safe" the pulse of the house beat softly. "The treasure buried; the room . . ." the pulse stopped short. Oh, was that the buried treasure? A moment later the light had faded. Out in the garden then? But the trees spun darkness for a wandering beam of sun. So fine, so rare, coolly sunk beneath the...

...guilty, yet helpless man. Doesn’t this sound familiar? Don’t our lives seem, sometimes, the result of a game of dice being played by someone/something bigger than ourselves, even bigger than life itself? Just the fact that we are who we are is nothing but a result of chance. This statement, beyond its recklessness appearance, has an explanation consisting of three moments of existences that are determined by the roulette. The first one goes back to before we’re born. Have you ever thought of how many billions of chances were there when your parents’ genetic material mixed to create you? I, for instance, could’ve been blond, tall and smart. Or short and dumb. Or anything. But, somehow, I turned out to be me, out of what appear to be infinite chances of who I could’ve been. And this process follows no logic or intervention from our part: is the work of randomness. The second moment, chronologically, involves our environment. Where we’re born, who our parents are, and the rest of conditions that welcome us to this world are the sort of aspects I include in this side of this pyramidal die. The third and final moment is composed of the things that are choices in our lives. This is also a consequence of luck because the construction of ourselves is the outcome of the decisions we make, which have a luck component. That...

...CAPM essay In the second scenario BBBY would use its $400 million in excess cash and borrow the remaining funds until Question 2 a) We will need to calculate the debt-to GDP ratio for each year separately in order to compute the total accumulation. The following equations and variables are used in question a) ∆b=g-t+r-y* b g-t=2 i=3 π=1 r=i-π=3-1=2 y=1 b=0,9 (=90%) Year 1 ∆b=2+2-1* 0,9=2,9 byear 1=90+2,9=92,9 Year 2 ∆b=2+2-1* 0,929=2,929 byear 2=92,9+2,929=95,829 Year 3 ∆b=2+2-1* 0,95829=2,95829 byear 3=95,829+2,95829=98,78729 Year 4 ∆b=2+2-1* 0,9878729=2,9878729 byear 4=98,78729+2,9878729=101,7751629 Year 5 ∆b=2+2-1* 1,017751629=3,017751629 byear 5=101,7751629+3,017751629=104,792914529 Therefore, after 5 years the debt-to-GDP ratio will be equal to 104,8 % (rounded to one decimal) b) The debt is not sustainable. The criteria to test whether debt is sustainable is as follows: ∆b=g-t+r-y* b=0 Plotting in the known variables results in the following: ∆b=2+2-1* b=2+b= 0 Solving for b gives the following: b= -2 Therefore, the initial debt should be -200% (so surplus) in order to maintain a sustainable debt. c) If the nominal interest rate rises to 10%, it would imply that the real interest rate is as follows: r=i-π=10-π Therefore, we know that: ∆b=g-t+r-y* b=2+10-π-1*0,9=2+9-π*0,9 The criteria to maintain a sustainable debt is as follows: ∆b=0 This implies that ∆b= 2+9-π*0,9=0 Solving for inflation results in the...

...I sat in a passenger seat of an old rental van with five of my closest friends, who just happen to be my band mates, staring off into the distance watching the lights fly by the window one by one. The view of the surrounding landscape turned suddenly into a completely unfamiliar area as if teleported to a new world. The unknown street names and buildings took over the area around us. Everything hit me all at once so unexpectedly, like the sound of a first lighting strike in the beginning of a storm. At that moment, nothing else mattered. This is finally happening. Andrew asked, “Do you think we will find a place to sleep every night?” Andrew was always the worried one of the bunch, but he played bass on stage he moved around like a madman. “3 weeks are a long time so probably not,” my vocalist Brandon chuckled out, “but I mean a majority of even the popular bands that go on a tour can not find a place to sleep every night so we can always just crash out in a Wal-Mart parking lot.” From my viewpoint, I could see my band member’s faces in the reflection of the rear view mirror as they all spoke about what they wanted to do at the upcoming shows; their eyes getting bigger than the cities we headed to in excitement. I still just sat there; having this profound realization in my mind while a smile slowly sprouted across my face. Over the course of 4 years, I spent more time alone in my room, sitting in an old desk chair wrapped up in duct tape to keep it from falling apart...

...A Good Man is Hard to Find. The grandmother focuses of showing that she cares nothing about the family by concerning herself with her hat. She builds a setting in her head that if she dies she will look like a lady without any concern for her family's well being. This idea that her hat, which makes her look like a lady in her mind, is more important than her family shows selfishness. Her mistaken ethics are aware from the beginning as the hat is the symbol for this negligence to her family. When they did indeed have a car wreck the grandmother was curled up under the dashboard with her hat still attached to her head. The hat represents that goal of still being a lady no matter the cost. While her grand children are in shock and shaking she is complaining that she thinks she has a hurt organ. The symbol of the brim of her hat smashed as she says “But nobody’s killed” in a frustrated tone shows her reluctance to give up that she was wrong. She will not give up this attempt at being a lady no matter what happens to her or grand children. As she confronts the Misfit her self assurance and idea that she is a lady slowly disintegrates away as she becomes more humble that she will most likely die. The symbolism of these disintegration is when her brim actually falls off of her hat and it realization that she is not a lady by any means. The symbolism of the hat to her concept of doing anything by any means necessary to be a considered a lady by everyone including herself is quite...

...Making sense of . . . LogNormal stock-price models in Exams MFE/3 and C/4 James W. Daniel Austin Actuarial Seminars http://www.actuarialseminars.com June 26, 2008 c Copyright 2007 by James W. Daniel; reproduction in whole or in part without the express permission of the author is forbidden. Foreword This document briefly describes the ideas behind the use of LogNormal models for stock prices in some of the material for Exams MFE and C of the Society of Actuaries and Exams 3 and 4 of the Casualty Actuarial Society. Not a traditional exam-prep study manual, it concentrates on explaining key ideas so that you can then understand the details presented in the textbooks or study manuals. It can be especially useful to anyone taking Exam C/4 without having studied the material for Exam MFE/3. 2 Chapter 1 LogNormal stock-price models 1.1 Why LogNormal models? Why learn about and use LogNormal models for stock prices? I could answer “Because it’s on the exam syllabi” or “Why not?”, but that wouldn’t be helpful. Instead, I’ll take a little space to motivate this. Suppose that the price of a stock or other asset at time 0 is known to be S(0) and we want to model its future price S(10) at time 10—note that some texts use the notation S0 and S10 instead. Let’s break the time interval from 0 to 10 into 10,000 pieces of length 0.001, and let’s let Sk stand for S(0.001k), the price at time 0.001k. I know the price S0 = S(0) and want to model the price S10000 = S(10)....

What is a better estimate of the VaR that takes account of autocorrelation? The correct multiplier for the variance is 10 + 2 × 9 × 0.12 + 2 × 8 × 0.122 + 2 × 7 × 0.123 + . . . + 2 × 0.129 = 10.417 The estimate of VaR should be increased to = 2.229 _________________________________________________________________________________ Ch 10 From Chapter 10, I went over 10.11, 10.12 (Answers in Book).

...Extension of the Snow Fun Ski Resort Problem Suppose that the operating cost of the snowmaking equipment is actually 30% higher than the owner had estimated, that is, $13,000 if the snowfall is heavy, $65,000 if it is moderate, and $117,000 if it is light. How will the increased operating cost affect the owner’s optimal decision? As shown above, the best decision now is to let the larger hotel run the ski resort and the profit is $45,000 Calculate the EVPI, and determine that maximum amount that could be paid for a perfect forecast. If the snowfall is more than 40”, the owner should operate the resort without a snowmaker (profit=$120,000, probability=40%). If the snowfall is between 20 to 40 inches or if it is less than 20 inches, the owner should let the larger hotel run the resort (profit=$45,000, probability=20%+40%=60%). EVPI = $120,000*0.40 + $45,000*0.60 = $75,000 Since the optimal profit without perfect information is $45,000, the maximum amount the owner can pay for perfect information is $75,000 - $45,000 = $30,000 1 Decision Tree Final Problem The NC Airport Authority is trying to solve a difficult problem with the over-crowded RaleighDurham airport. There are three options to consider: A. The airport could be totally redesigned and rebuilt at a cost of $8.2 million. The present value of increased revenue from a new airport is in question. There is a 70% chance this present value would be $11 million, a 20% chance present value would be $5 million, and a 10%...

When the date of speech came nearer I panicked and kept forgetting my lines. My teacher guided me to practice before a mirror, it helped but not enough to calm my nerves. After days of practicing before my parents and the mirror I was still not ready. My thoughts were focused upon how my voice would tremble and I would lose feeling in my legs. It was not till I was on stage and I started speaking that I paid attention to what I was saying. I had given the preparation my best effort and if my voice is going to tremble it did not matter anymore. With this thought in my I found my voice strengthen. This was a moment of revelation for me, I was realizing for the first time that I can do this. When I stopped avoiding looking at the audience I realized that I was not afraid anymore. I can give my best or worst performance and it will still be over either way, with this thought I gave it all my effort. The applause I got at the...
