Stakeholder management as a predictor of CEO compensation: main effects and interactions with financial performance

Abstract: We test the effects of stakeholder management on CEOs' salaries, bonuses, stock options, and total compensation. We also examine the extent to which the interaction of stakeholder management and financial performance determines compensation. Using a longitudinal database of 406 Fortune 1000 firms, our results suggest that stakeholder management is relevant to boards of directors when setting CEO compensation. Specifically, we found a significant, negative main effect of stakeholder management on CEO salaries. Further, we found that stakeholder management typically reduces the rewards CEOs may get for increasing levels of financial performance. In tandem, these results indicate that CEOs may jeopardize their personal wealth by pursuing stakeholder-related initiatives. Copyright © 2005 John Wiley & Sons, Ltd.

After the ink dries: the interaction of trust and control in us-based international joint ventures

Abstract: This study empirically examines the moderating effects of age and partner trust on the relationship between control mechanisms and perceptions of performance in 129 US-based international joint ventures (IJVs). A reliance on formal control mechanisms and general managers’ perceptions of IJV performance were found to be positively related in younger IJVs, but this relationship became negative in more mature IJVs. In addition, social control mechanisms and perceptions of IJV performance were positively related, but only in the presence of affect-based trust between the parents.

Free-Standing Layer-by-Layer Assembled Films of Magnetite Nanoparticles

Abstract: A new technique for preparation of free-standing ultrathin films is presented. These films were made by layer-by-layer (LBL) deposition process, which is utilized for coatings on solid substrates and colloids. A film composed of alternating layers of magnetite nanoparticles and poly(diallyldimethylammonium bromide) was assembled on cellulose acetate, which was subsequently dissolved in acetone. From the suspended state, the LBL film can be transferred onto any solid or porous support. The strength of the film was observed to significantly increase when every other layer of magnetite was replaced with a layer of alumosilicate sheets serving as a molecular framework for the assembly.

Effect of warming and drought on grassland microbial communities

Abstract: The soil microbiome is responsible for mediating key ecological processes; however, little is known about its sensitivity to climate change. Observed increases in global temperatures and alteration to rainfall patterns, due to anthropogenic release of greenhouse gases, will likely have a strong influence on soil microbial communities and ultimately the ecosystem services they provide. Therefore, it is vital to understand how soil microbial communities will respond to future climate change scenarios. To this end, we surveyed the abundance, diversity and structure of microbial communities over a 2-year period from a long-term in situ warming experiment that experienced a moderate natural drought. We found the warming treatment and soil water budgets strongly influence bacterial population size and diversity. In normal precipitation years, the warming treatment significantly increased microbial population size 40–150% but decreased diversity and significantly changed the composition of the community when compared with the unwarmed controls. However during drought conditions, the warming treatment significantly reduced soil moisture thereby creating unfavorable growth conditions that led to a 50–80% reduction in the microbial population size when compared with the control. Warmed plots also saw an increase in species richness, diversity and evenness; however, community composition was unaffected suggesting that few phylotypes may be active under these stressful conditions. Our results indicate that under warmed conditions, ecosystem water budget regulates the abundance and diversity of microbial populations and that rainfall timing is critical at the onset of drought for sustaining microbial populations.

Clique Relaxations in Social Network Analysis: The Maximum k-Plex Problem

Abstract: This paper introduces and studies the maximum k-plex problem, which arises in social network analysis and has wider applicability in several important areas employing graph-based data mining. After establishing NP-completeness of the decision version of the problem on arbitrary graphs, an integer programming formulation is presented, followed by a polyhedral study to identify combinatorial valid inequalities and facets. A branch-and-cut algorithm is implemented and tested on proposed benchmark instances. An algorithmic approach is developed exploiting the graph-theoretic properties of a k-plex that is effective in solving the problem to optimality on very large, sparse graphs such as the power law graphs frequently encountered in the applications of interest.
