Multi-Level Issues in International HRM: Mean Differences, Explained Variance, and Moderated Relationships

[Excerpt] While neither denying that differences in HR systems exist, nor that some of the variety of practices is due to real differences across countries, we will attempt to dissect the issue of International HRM using ideas, concepts, and models emerging from multilevel theory and research. We posit that three ideas are critical to this line of research: Mean differences in the use of HR practices across countries, the amount of variance in HR practices that is explained by countries, and the extent to which countries (or specifically culture) moderates the relationships between HR practices and outcomes. Our conclusion is that these differences may not be as large as we think they are, and may in fact be due less to differences in culture and more to differences in institutional contexts

Environmental Regulations and the Structure of U.S. Hog Farms

The U.S hog production industry has been continually subjected to rapid structural changes since the early 1990s. The industry's move towards more concentrated large hog farms and geographical concentration of such farms, have triggered public concerns over the dangers such big animal feeding operations are likely to pose to the waters of the country. This study investigates the implications of state-level environmental regulations on the structure of hog farms. The results of this study suggest that environmental regulations will result in one of three possible scenarios: (1) a more competitive industry in which small hog operations are not adversely affected which will allow more small operations to enter rather than exit the industry; (2) a more concentrated hog production industry in which large operations survive while small operations exit the industry; (3) no change in the structure of the industry where both sizes of operations are not significantly affected by environmental stringency.Perfect competition, U.S. hog production industry, Environmental regulations, Environmental Economics and Policy, Livestock Production/Industries,

Magnetic hallmarks of viscous electron flow in graphene

We propose a protocol to identify spatial hallmarks of viscous electron flow in graphene and other two-dimensional viscous electron fluids. We predict that the profile of the magnetic field generated by hydrodynamic electron currents flowing in confined geometries displays unambiguous features linked to whirlpools and backflow near current injectors. We also show that the same profile sheds light on the nature of the boundary conditions describing friction exerted on the electron fluid by the edges of the sample. Our predictions are within reach of vector magnetometry based on nitrogen-vacancy centers embedded in a diamond slab mounted onto a graphene layer.Comment: 5 pages, 6 figure

Mapping dynamical heterogeneity in structural glasses to correlated fluctuations of the time variables

Dynamical heterogeneities -- strong fluctuations near the glass transition -- are believed to be crucial to explain much of the glass transition phenomenology. One possible hypothesis for their origin is that they emerge from soft (Goldstone) modes associated with a broken continuous symmetry under time reparametrizations. To test this hypothesis, we use numerical simulation data from four glass-forming models to construct coarse grained observables that probe the dynamical heterogeneity, and decompose the fluctuations of these observables into two transverse components associated with the postulated time-fluctuation soft modes and a longitudinal component unrelated to them. We find that as temperature is lowered and timescales are increased, the time reparametrization fluctuations become increasingly dominant, and that their correlation volumes grow together with the correlation volumes of the dynamical heterogeneities, while the correlation volumes for longitudinal fluctuations remain small.Comment: v4: Detailed analysis of transverse and longitudinal parts.

Soy protein enzymatic hydrolysis and polysaccharides interactions: differential performance on kinetic adsorption at air-water interface

The objective of the work was to study the impact of soy protein hydrolysis on kinetic adsorption to the air-water interface and the effect of polysaccharides addition. Was used soy protein (SP) and theirs hydrolysates of 2% (H1) and 5.4% (H2) degree of hydrolysis. The polysaccharides (PS) used were a surface active one called E4M and a non-surface active one, lamda carrageenan (C). The dynamic surface pressure of interfacial films was evaluated with a drop tensiometer. In this contribution, we have determined the kinetic parameters of adsorption to the air-water interface which determined the penetration (Kp) and rearrangement (Kr) rates of SP, H1, H2 and PS, as well as their mixed systems. It was observed an increase of Kp and Kr when the protein were hydrolyzed (from SP to H1), however, when degree of hydrolysis progresses to H2 the parameters decreased again. In other hand, considerable differences were not found between these two PS studied concerning the Kp to air-water interface at these conditions. In spite of the different surface active nature of the PS, the proteins seem to control the behavior of the protein-PS interactions. However, when Kr of mixed systems was analyzed, the degree of hydrolysis and PS nature started to have a huge importance. Hence, it could be observed synergic or antagonic effects on Kr of biopolymers at liquid interface depending to the degree of hydrolysis of protein analyzed and the type of PS selected.CYTED through project 105PI0274CYCYT through grant AGL2007-60045Junta de Andalucía through grant PO6-AGR-01535Universidad de Buenos Aires, Agencia Nacional de Promoción Científica y Tecnológica (PICT 2008-1901) and Consejo Nacional de Investigaciones Científicas y Técnicas de la República Argentin

Professional Perspectives: Views of Service Needs for Individuals Diagnosed With Frontotemporal Dementia and Their Families

The purpose of this study was to explore professional\u27s perspectives on the service needs for people with Frontotemporal Dementia (FTD) and their families. A qualitative research design was used to obtain data from (n=4) four professionals from a variety of work settings. The results of this study supported previous literature in identifying the challenges in supporting and lack of services for people with FTD and their caregivers. The major theme which emerged in this research was that there is a need for FTD specific services. The subthemes which emerged to support this theme included: physical activities, more staffing, individualization, collaboration, financial barriers, and education. Implications for future include the need for social workers to provide education and advocate for service needs for people with FTD and their caregiver in multiple levels. In additional to exploring professional perspectives is imperative that future research explore the service and support needs from the perspective of those providing care for individuals diagnosed with FTD

Economic Moat: A Line of Defense for the Defense Industry

Defense contractor financial performance is traditionally measured using accounting profit. In academic literature, accounting profit has been proxied through different applications of accounting rates of return. However, the use of these rates pose certain limitations. First, accounting rates of return have been applied inconsistently. Next, academic research has not typically assessed accounting returns against a firms opportunity costs. As a result, there is a literature gap in defense research that assesses whether defense contractors earn sustainable returns beyond the cost to produce those returns
