Outsourcing the Human Resource Function: Environmental and Organizational Characteristics that Affect HR Performance

A theoretical model is presented that identifies environmental and organizational characteristics that affect human resource (HR) performance in an organization. Specifically, we address the issue of when and under what circumstances does HR outsourcing contribute value to the firm by attempting to identify environmental and organizational characteristics that affect HR department performance and how HR outsourcing mediates that relationship. We propose that supplier competition in the HR provider market has a direct effect on the amount of HR outsourcing which in turn has a direct effect on HR performance. Environmental uncertainty (primary, competitive, and supplier) is proposed to moderate the relationship between amount of HR outsourcing and HR performance while asset specificity is proposed to moderate the relationship between supplier competition and amount of HR outsourcing.

A Study of Attrition in a Respiratory Care Associate Degree Program in a Northeast Tennessee Community College.

The Walters State Community College\u27s Respiratory Care (WSCC RC) Program had a 33% attrition rate during a five-year period from 1999 through 2003. This study analyzed demographic, pre-admission, and academic variables to identify reasons for attrition within the WSCC RC program. The population size was 90 students; this was the entire population of five consecutive classes graduating during a five-year period from 1999 through 2003. The criterion variables included high school attended, gender, age, college-level GPA, college-level credit hours, and developmental requirements. Statistical tests revealed that college-level GPA, college-level credit hours, and developmental requirements influenced persistence within the population. The chi-square test of significance was conducted to compare the attrition rate of the students. There was a significant difference in persistence for GPA, X2(1) = 9.844, p = .002; college credit hours, X2(2) = 14.943, p = .001; and developmental students, X2(1) = 4.582, p= .032

A Follow-Up Study Of The Occupational Pursuits Of Participants in 4-H Club Work In Okmulgee County, Okmulgee, Oklahoma From 1940 to 1955

The 4-H Club program has been far-reaching in developing youth. Some two million other 4-H\u27 ers join Okmulgee County 4-H Club members when they say, I Pledge: My head to clearer thinking, My heart to greater loyalty My hands to larger service and My health to better living for, My club, my community, and my country. This motto which is learned by most 4-H club members and is said in the ritualistic opening of all 4-H meetings is soon to become a vital part in the molding of a club member\u27s personality. In most instances, the sheer delight and satisfaction derived from carrying a 4-H club project even though the member may only share in spasmodic intervals of monetary returns from such projects. The member gets his or her satisfaction from learning a skill or perfecting their habits of workmanship. The member gets his or her satisfaction from learning a skill or perfecting their habits of workmanship. The ultimate and primary purpose of all 4-H club activities is to aid in the development of future citizens of tomorrow. The devices and methods used are only a necessary means to an end

zCOSMOS: A large VLT/VIMOS redshift survey covering 0 < z < 3 in the COSMOS field

zCOSMOS is a large-redshift survey that is being undertaken in the COSMOS field using 600 hr of observation with the VIMOS spectrograph on the 8 m VLT. The survey is designed to characterize the environments of COSMOS galaxies from the 100 kpc scales of galaxy groups up to the 100 Mpc scale of the cosmic web and to produce diagnostic information on galaxies and active galactic nuclei. The zCOSMOS survey consists of two parts: (1) zCOSMOSbright, a magnitude-limited I-band I_(AB) < 22.5 sample of about 20,000 galaxies with 0.1 < z < 1.2 covering the whole 1.7 deg^2 COSMOS ACS field, for which the survey parameters at z ~ 0.7 are designed to be directly comparable to those of the 2dFGRS at z ~ 0.1; and (2) zCOSMOS-deep, a survey of approximately 10,000 galaxies selected through color-selection criteria to have 1.4 < z < 3.0, within the central 1 deg^2. This paper describes the survey design and the construction of the target catalogs and briefly outlines the observational program and the data pipeline. In the first observing season, spectra of 1303 zCOSMOS-bright targets and 977 zCOSMOS-deep targets have been obtained. These are briefly analyzed to demonstrate the characteristics that may be expected from zCOSMOS, and particularly zCOSMOS-bright, when it is finally completed between 2008 and 2009. The power of combining spectroscopic and photometric redshifts is demonstrated, especially in correctly identifying the emission line in single-line spectra and in determining which of the less reliable spectroscopic redshifts are correct and which are incorrect. These techniques bring the overall success rate in the zCOSMOS-bright so far to almost 90% and to above 97% in the 0.5 < z < 0.8 redshift range. Our zCOSMOS-deep spectra demonstrate the power of our selection techniques to isolate high-redshift galaxies at 1.4 < z < 3.0 and of VIMOS to measure their redshifts using ultraviolet absorption lines

Photo-z Performance for Precision Cosmology II : Empirical Verification

The success of future large scale weak lensing surveys will critically depend on the accurate estimation of photometric redshifts of very large samples of galaxies. This in turn depends on both the quality of the photometric data and the photo-z estimators. In a previous study, (Bordoloi et al. 2010) we focussed primarily on the impact of photometric quality on photo-z estimates and on the development of novel techniques to construct the N(z) of tomographic bins at the high level of precision required for precision cosmology, as well as the correction of issues such as imprecise corrections for Galactic reddening. We used the same set of templates to generate the simulated photometry as were then used in the photo-z code, thereby removing any effects of "template error". In this work we now include the effects of "template error" by generating simulated photometric data set from actual COSMOS photometry. We use the trick of simulating redder photometry of galaxies at higher redshifts by using a bluer set of passbands on low z galaxies with known redshifts. We find that "template error" is a rather small factor in photo-z performance, at the photometric precision and filter complement expected for all-sky surveys. With only a small sub-set of training galaxies with spectroscopic redshifts, it is in principle possible to construct tomographic redshift bins whose mean redshift is known, from photo-z alone, to the required accuracy of 0.002(1+z).Comment: 7 pages, 5 figures, accepted for publication in MNRA

Undoped Electron-Hole Bilayers in a GaAs/AlGaAs Double Quantum Well

We present the fabrication details of completely undoped electron-hole bilayer devices in a GaAs/AlGaAs double quantum well heterostructure with a 30 nm barrier. These devices have independently tunable densities of the two-dimensional electron gas and two-dimensional hole gas. We report four-terminal transport measurements of the independently contacted electron and hole layers with balanced densities from $1.2 \times 10^{11}$cm$^{-2}$ down to $4 \times 10^{10}$ cm$^{-2}$ at $T = 300 mK$. The mobilities can exceed $1 \times 10^{6}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for electrons and $4 \times 10^{5}$ cm$^{2}$ V$^{-1}$ s$^{-1}$ for holes.Comment: 3 pages, 3 figure
