Explaining Sales Pay Strategy Using Agency, Transaction Cost and Resource Dependence Theories

The purpose of this study was to investigate, using data gathered from 325 French-Canadian organizations, the influence of key constructs related to agency, transaction cost and resource dependence theories on the proportion of salary in sales compensation. Level of task programmability, capacity to observe behavior, career opportunities and financial resources offered were associated with an increased use of salary pay. In contrast, difficulty of measuring result outcomes, availability of product/service-related resources and high marginal sales force productivity were associated with decreased use of the salary component. Results supported the argument that integration of multiple theoretical perspectives offered a better explanation of pay policy. However, the results have not supported the ability of market and selling uncertainty to predict the proportion of salary L'objectif de cette étude était d'examiner, auprès d'un échantillon de 325 organisations, l'influence des construits clés relatifs à la théorie de l'agence, la théorie des coûts de transaction et la théorie de la dépendence des ressource sur la proportion du salaire dans l'enveloppe de la rémunération directe du personnel de vente. Le niveau de programmation des tâches, la capacité à observer les comportements, les opportunités de carrière et les ressources financières offertes étaient associés à une augmentation du recours de la composante salariale. En revanche, le degré de difficulté à mesurer les résultats, la disponibilité de ressources reliés aux produits/services et un grand différentiel de performance étaient associés à une diminution de la composante salaire. Les résultats supportent l'argument de l'intégration d'une multitude de perspecttives théoriques pour expliquer le choix des stratégies salariales.Sales, compensation, agency theory, cost analysis theory, resource dependence theory, Représentants aux ventes, rémunération, théorie de l'agence, théorie des coûts de transaction, théorie de la dépendance des ressources

The Role of Organizational Justice in Pay and Employee Benefit Satisfaction, and Its Effects on Work Attitudes

The objective of our study is to provide a complementary approach with regard to organizational justice in the domain of compensation. It presents research undertaken on a sample of six hundred employees in three different Canadian organizations. The results reveal that employees distinguish clearly between pay satisfaction and benefit satisfaction, and that distributive justice perceptions are better predictors of pay satisfaction than procedural justice perceptions. This result is reversed for employee benefit satisfaction: procedural justice perceptions are better predictors than distributive justice perceptions. Lastly, the results show that distributive justice perceptions with regard to pay play a more important role than procedural justice in job satisfaction and satisfaction with the organization. Cet article a pour but d'apporter un éclairage complémentaire en ce qui concerne la justice organisationnelle dans le domaine de la rémunération. On y fait état de recherches réalisées auprès de six cents salariés appartenant à trois organisations canadiennes différentes. Les résultats révèlent que les salariés dissocient bien la satisfaction à l'égard du salaire, de la satisfaction à l'égard des avantages sociaux. Ils montrent également que les perceptions de justice distributives permettent de mieux prédire la satisfaction à l'égard du salaire que les perceptions de justice procédurales. Le résultat est inverse en ce qui concerne la satisfaction à l'égard des avantages sociaux : les perceptions de justice procédurales sont de meilleurs prédicteurs que les perceptions de justice distributives. Ils montrent enfin que la perception de justice distributive concernant les salaires joue un rôle plus important que la justice procédurale dans la satisfaction à l'égard du travail et à l'égard de l'entreprise.Organizational justice, pay and benefit satisfaction, work attitudes, Justice organisationnelle, satisfaction du salaire, satisfaction des avantages sociaux, attitudes au travail

Pure-hydrogen 3D model atmospheres of cool white dwarfs

A sequence of pure-hydrogen CO5BOLD 3D model atmospheres of DA white dwarfs is presented for a surface gravity of log g = 8 and effective temperatures from 6000 to 13,000 K. We show that convective properties, such as flow velocities, characteristic granulation size and intensity contrast of the granulation patterns, change significantly over this range. We demonstrate that these 3D simulations are not sensitive to numerical parameters unlike the 1D structures that considerably depend on the mixing-length parameters. We conclude that 3D spectra can be used directly in the spectroscopic analyses of DA white dwarfs. We confirm the result of an earlier preliminary study that 3D model spectra provide a much better characterization of the mass distribution of white dwarfs and that shortcomings of the 1D mixing-length theory are responsible for the spurious high-log g determinations of cool white dwarfs. In particular, the 1D theory is unable to account for the cooling effect of the convective overshoot in the upper atmospheres.Comment: 14 pages, 17 figures, accepted for publication in Astronomy and Astrophysic

Spectroscopic analysis of DA white dwarfs with 3D model atmospheres

We present the first grid of mean three-dimensional (3D) spectra for pure-hydrogen (DA) white dwarfs based on 3D model atmospheres. We use CO5BOLD radiation-hydrodynamics 3D simulations instead of the mixing-length theory for the treatment of convection. The simulations cover the effective temperature range of 6000 < Teff (K) < 15,000 and the surface gravity range of 7 < log g < 9 where the large majority of DAs with a convective atmosphere are located. We rely on horizontally averaged 3D structures (over constant Rosseland optical depth) to compute spectra. It is demonstrated that our spectra can be smoothly connected to their 1D counterparts at higher and lower Teff where the 3D effects are small. Analytical functions are provided in order to convert spectroscopically determined 1D effective temperatures and surface gravities to 3D atmospheric parameters. We apply our improved models to well studied spectroscopic data sets from the Sloan Digital Sky Survey and the White Dwarf Catalog. We confirm that the so-called high-log g problem is not present when employing spectra and that the issue was caused by inaccuracies in the 1D mixing-length approach. The white dwarfs with a radiative and a convective atmosphere have derived mean masses that are the same within ~0.01 Msun, in much better agreement with our understanding of stellar evolution. Furthermore, the 3D atmospheric parameters are in better agreement with independent Teff and log g values from photometric and parallax measurements.Comment: 15 pages, 18 figures, 10 pages online appendix, accepted for publication in Astronomy and Astrophysic

Revisiting the Cooling Flow Problem in Galaxies, Groups, and Clusters of Galaxies

We present a study of 107 galaxies, groups, and clusters spanning ~3 orders of magnitude in mass, ~5 orders of magnitude in central galaxy star formation rate (SFR), ~4 orders of magnitude in the classical cooling rate (dM/dt) of the intracluster medium (ICM), and ~5 orders of magnitude in the central black hole accretion rate. For each system in this sample, we measure dM/dt using archival Chandra X-ray data and acquire the SFR and systematic uncertainty in the SFR by combining over 330 estimates from dozens of literature sources. With these data, we estimate the efficiency with which the ICM cools and forms stars, finding e_cool = SFR/(dM/dt) = 1.4 +/- 0.4% for systems with dM/dt > 30 Msun/yr. For these systems, we measure a slope in the SFR-dM/dt relation greater than unity, suggesting that the systems with the strongest cool cores are also cooling more efficiently. We propose that this may be related to, on average, higher black hole accretion rates in the strongest cool cores, which could influence the total amount (saturating near the Eddington rate) and dominant mode (mechanical vs radiative) of feedback. For systems with dM/dt < 30 Msun/yr, we find that the SFR and dM/dt are uncorrelated, and show that this is consistent with star formation being fueled at a low (but dominant) level by recycled ISM gas in these systems. We find an intrinsic log-normal scatter in SFR at fixed dM/dt of 0.52 +/- 0.06 dex, suggesting that cooling is tightly self-regulated over very long timescales, but can vary dramatically on short timescales. There is weak evidence that this scatter may be related to the feedback mechanism, with the scatter being minimized (~0.4 dex) in systems for which the mechanical feedback power is within a factor of two of the cooling luminosity.Comment: 16 pages, 10 figures, 6 tables.

Quantum Monte Carlo Study of Strongly Correlated Electrons: Cellular Dynamical Mean-Field Theory

We study the Hubbard model using the Cellular Dynamical Mean-Field Theory (CDMFT) with quantum Monte Carlo (QMC) simulations. We present the algorithmic details of CDMFT with the Hirsch-Fye QMC method for the solution of the self-consistently embedded quantum cluster problem. We use the one- and two-dimensional half-filled Hubbard model to gauge the performance of CDMFT+QMC particularly for small clusters by comparing with the exact results and also with other quantum cluster methods. We calculate single-particle Green's functions and self-energies on small clusters to study their size dependence in one- and two-dimensions.Comment: 14 pages, 18 figure
