DIFFERENCES IN RSI AND PEAK GROUND REACTION FORCE FOR DROP REBOUND JUMPS FROM A HANG AND BOX FOR FEMALE SUBJECTS

The aim of this study was to examine differences between drop jump rebound from a box (DJB) and hanging position (DJH). The volunteers were 14 college aged women who were healthy and physically active. Jumps were assessed from a 30 cm drop onto a force platform. Jump height, contact time, reactive strength index, and peak vertical ground reaction force were compared for the two jumps using a Paired T-test. There were no significant differences in peak ground reaction force or jump height between the DJB and DJH (p > 0.05). Contact time was found to be less (p = 0.033) and RSI higher (p = 0.012) for the DJB. Thus, the DJB would be recommended for power training over the DJH. The results of the current study may aid coaches to prescribe the optimal drop rebound jump position for the training of their athletes

Refusing to Endorse. A must Explanation for Pejoratives.

In her analysis of pejoratives, Eva Picardi rejects a too sharp separation between descriptive and expressive content. I reconstruct some of her arguments, endorsing Eva’s criticism of Williamson’s analysis of Dummett and developing a suggestion by Manuel Garcia Carpintero on a speech act analysis of pejoratives. Eva’s main concern is accounting for our instinctive refusal to endorse an assertion containing pejoratives because it suggests a picture of reality we do not share. Her stance might be further developed claiming that uses of pejoratives not only suggest, but also promote a wrong picture of reality. Our refusal to endorse implies rejecting not only a wrong picture of reality but also a call for participation to what that picture promotes

Helium Nova on a Very Massive White Dwarf -- A Light Curve Model of V445 Puppis (2000) Revised

V445 Pup (2000) is a unique object identified as a helium nova. Color indexes during the outburst are consistent with those of free-free emission. We present a free-free emission dominated light curve model of V445 Pup on the basis of the optically thick wind theory. Our light curve fitting shows that (1) the white dwarf (WD) mass is very massive (M_WD \gtrsim 1.35 M_\sun), and (2) a half of the accreted matter remains on the WD, both of which suggest that the increasing WD mass. Therefore, V445 Pup is a strong candidate of Type Ia supernova progenitor. The estimated distance to V445 Pup is now consistent with the recent observational suggestions, 3.5 < d < 6.5 kpc. A helium star companion is consistent with the brightness of m_v=14.5 mag just before the outburst, if it is a little bit evolved hot (\log T (K) \gtrsim 4.5) star with the mass of M_He \gtrsim 0.8 M_\sun. We then emphasize importance of observations in the near future quiescent phase after the thick circumstellar dust dissipates away, especially its color and magnitude to specify the nature of the companion star. We have also calculated helium ignition masses for helium shell flashes against various helium accretion rates and discussed the recurrence period of helium novae.Comment: 8 pages including 12 figures, to appear in Ap

Valuing Coca-Cola Using The Free Cash Flow To Equity Valuation Model

In this paper, we provide a detailed example of applying the free cash flow to equity valuation model proposed in Damodaran (2006). Damodaran (2006) argues that the value of a stock is the discounted present value of the future free cash flow to equity discounted at the cost of equity. We combine the free cash flow to equity model with the super-normal growth model to determine the current value of Coca-Cola. At the time of this paper, we determined a value of Coca-Cola at $161 billion using the free cash flow to equity model, and the actual market value of Coca-Cola was$150 billion

Gender And Attitude Toward An International Career: A Survey Of Russian Nationals

This paper examines attitudes of Russian MBA students toward international careers and finds that gender is not an issue but that respondents with family constraints were less favorable toward an international career.  Respondents who are male, are single, or do not have children were slightly favorable toward international careers.  Women and respondents with spouses without a career were neutral toward international careers.  Respondents who are married, respondents with children, and respondents with a spouse with a career, were slightly unfavorable toward an international career.  The results of this survey indicate that Russian MBA students are, on average, only slightly favorable toward international careers.  These results contrast with an earlier study that found a stronger preference for international careers among Russian MBA students.  Current MBA students in Moscow have more career opportunities than before.  The results are based on the responses of twenty-nine Russian students in an AACSB accredited MBA program in Moscow who speak both Russian and English and work for an international company or agency

Applying The Teacher Scholar Model In The School Of Business

The teacher-scholar model was proposed in Boyer (1990) and defines four dimensions of scholarship: &nbsp;1) discovery, 2) integration, 3) application, and 4) teaching. In this paper, we describe the characteristics of scholarship, the theory of the scholarship of teaching, the excellent teacher, and undergraduate research and scholarship.&nbsp; We then show how the teacher-scholar model is applied at one University for annual faculty evaluations.&nbsp

Calculating The Beta Coefficient And Required Rate Of Return For Coca-Cola

In this paper, we demonstrate how to compute the required rate of return for Coca-Cola using modern portfolio theory with data downloaded from the internet.  We demonstrate how to calculate monthly returns for the index and Coca-Cola and how to use the returns to compute the beta coefficient and the required rate of return using the downloaded data.  We show how to validate the data for the market index and the company and how to compute the returns using the dividend and stock split adjusted prices.  We demonstrate how to graph the characteristic line for Coca-Cola and use the graph to check that the regression was run correctly.  We use Coca-Cola and the S&amp;P 500 Index in this paper, but any company listed on Yahoo! Finance can be used as the example.  This paper can be used as the basis of a lecture on intermediate corporate finance or investments to demonstrate the process using a real company

INTEGRAL observations of the Small Magellanic Cloud

The first INTEGRAL observations of the Small Magellanic Cloud (carried out in 2003) are reported in which two sources are clearly detected. The first source, SMC X-1, shows a hard X-ray eclipse and measurements of its pulse period indicate a continuation of the long-term spin-up now covering ~30 years. The second source is likely to be a high mass X-ray binary, and shows a potential periodicity of 6.8s in the IBIS lightcurve. An exact X-ray or optical counterpart cannot be designated, but a number of proposed counterparts are discussed. One of these possible counterparts shows a strong coherent optical modulation at ~2.7d, which, together with the measured hard X-ray pulse period, would lead to this INTEGRAL source being classified as the fourth known high mass Roche lobe overflow system.Comment: Accepted for publication in MNRA
