Salary Inversion in Business Schools: Does a Rising Tide Lift All Boats?

The paper analyzes AACSB salary survey information from 1979 to 2008. The question addressed in this analysis is whether salary inversion is widespread across the three business disciplines of accounting, economics, and finance. We find limited evidence of mean level inversions, which is concentrated in recent years. Stochastic dominance methods confirm these results. We also develop a measure of salary dominance based on comparing the distribution of reported salaries. This statistic shows a significant trend towards salary inversion in finance and accounting

ΔSCOPE: A New Method to Quantify 3D Biological Structures and Identify Differences in Zebrafish Forebrain Development

Research in the life sciences has traditionally relied on the analysis of clear morphological phenotypes, which are often revealed using increasingly powerful microscopy techniques analyzed as maximum intensity projections (MIPs). However, as biology turns towards the analysis of more subtle phenotypes, MIPs and qualitative approaches are failing to adequately describe these phenotypes. To address these limitations and quantitatively analyze the three-dimensional (3D) spatial relationships of biological structures, we developed the computational method and program called ∆SCOPE (Changes in Spatial Cylindrical Coordinate Orientation using PCA Examination). Our approach uses the fluorescent signal distribution within a 3D data set and reorients the fluorescent signal to a relative biological reference structure. This approach enables quantification and statistical analysis of spatial relationships and signal density in 3D multichannel signals that are positioned around a well-defined structure contained in a reference channel. We validated the application of ∆SCOPE by analyzing normal axon and glial cell guidance in the zebrafish forebrain and by quantify- ing the commissural phenotypes associated with abnormal Slit guidance cue expression in the forebrain. Despite commissural phenotypes which display disruptions to the reference structure, ∆SCOPE was able to detect subtle, previously uncharacterized changes in zebrafish forebrain midline crossing axons and glia. This method has been developed as a user-friendly, open source program. We propose that ∆SCOPE is an innovative approach to advancing the state of image quantification in the field of high resolution microscopy, and that the techniques presented here are of broad applications to the life science field

Finite element simulation of three-dimensional free-surface flow problems

An adaptive finite element algorithm is described for the stable solution of three-dimensional free-surface-flow problems based primarily on the use of node movement. The algorithm also includes a discrete remeshing procedure which enhances its accuracy and robustness. The spatial discretisation allows an isoparametric piecewise-quadratic approximation of the domain geometry for accurate resolution of the curved free surface. The technique is illustrated through an implementation for surface-tension-dominated viscous flows modelled in terms of the Stokes equations with suitable boundary conditions on the deforming free surface. Two three-dimensional test problems are used to demonstrate the performance of the method: a liquid bridge problem and the formation of a fluid droplet

An efficient adaptive multigrid algorithm for predicting thin film flow on surfaces containing localised topographic features

Gravity-driven continuous thin film flow over a plane, containing well-defined single and grouped topographic features, is modelled as a Stokes flow using lubrication theory. The associated time dependent, nonlinear, coupled set of governing equations are solved using a Full Approximation Storage (FAS) Multigrid algorithm by employing automatic mesh adaptivity, the power efficiency and accuracy of which is demonstrated by comparing the results with corresponding global fine-mesh solutions.. These show that automatic grid refinement effectively restricts the use of find grids to regions of rapid flow development which, for flow over the topographies considered, includes the topography itself, the upstream Capillary ridge, downstream sure region, and the characteristic bow wave. It is shown that for the accurate solution of such flow problems, adaptive Multigridding offers increased flexibility together with a significant reduction in memory requirement. This is further demonstrated by solving the problem of transient flow over a trench topography, generated by a sinusoidally varying inlet condition

Near yrast study of the fpg shell nuclei 58Ni, 61Cu, and 61Zn

The medium spin, near yrast states of the fpg shell nuclei 58Ni, 61Cu, and 61Zn have been studied following the fusion evaporation of a 24Mg beam and a 40Ca target. Discrete transitions were unambiguously identified using the AYEBALL gamma-ray array in conjunction with the Argonne fragment mass analyzer and a split anode ionization chamber. The decay schemes of 5828Ni, 6129Cu, and 6130Zn have been extended with the results of gamma-gamma coincidences and directional correlation from oriented state measurements used to determine the level excitation energies, spins, and parities of a number of near yrast states. The decay schemes deduced are compared with previous work and interpreted in terms of shell model calculations, with a restricted basis of the f5/2, p3/2, p1/2 orbitals outside a 5628Ni core, and either the g9/2 orbital with a closed core, or f7/2 excitations from the core

Competing T = 0 and T = 1 structures in the N = Z nucleus 3162Ga

The low-lying levels in the odd-odd N = Z nucleus 62Ga have been identified for the first time. These data reveal a cascade of stretched-E2 transitions based on a T = 0, 1+ bandhead which decays directly to the T = 1, 0+ ground state. The observed levels are interpreted in the context of theshell model, using as a basis, the pf5/2g9/2 orbits with a 56Ni core

The role of psychologists in international migration research: complementing other expertise and an interdisciplinary way forward

This research note addresses the current and potential future role of psychologists in the study of international migration. It reviews ways in which psychologists have contributed to the study of migration, as well as ways in which psychological scholarship could be integrated with work from other social science fields. Broadly, the note discusses four major contributions that psychology brings to the study of international migration—studying migrants’ internal psychological experiences, incorporating a developmental perspective, conducting experimental studies, and integrating across levels of analysis. Given the position of psychology as a ‘hub science’ connecting more traditional social sciences with health and medical sciences, we argue for a more prominent role for psychologists within the study of international migration. Such a role is intended to complement the roles of other social scientists and to create a more interdisciplinary way forward for the field of migration studies. The research note concludes with an agenda for further scholarship on migration.Development Psychopathology in context: clinical setting
