Servant leadership: Validation of a short form of the SL-28

Abstract: Although research on servant leadership has been expanding over the past several years, a concise, valid scale for assessing global servant leadership has been lacking. In the current investigation a 7-item measure of global servant leadership (SL-7), based on Liden, Wayne, Zhao, and Henderson's (2008) 28-item servant leadership measure (SL-28), is introduced. Psychometric properties of the SL-7 were assessed at the individual level with data collected from 729 undergraduate students, 218 graduate students, and 552 leader–follower dyads from 11 organizations, and at the team level with a study consisting of a total of 71 ongoing intact work teams. Results across three independent studies with six samples showed correlations between the SL-7 and SL-28 scales ranging from .78 to .97, internal consistency reliabilities over .80 in all samples, and significant criterion-related validities for the SL-7 that parallel those found with the SL-28.

Nanostructured semiconductor films for photocatalysis. Photoelectrochemical behavior of SnO2/TiO2 composite systems and its role in photocatalytic degradation of a textile azo dye

Abstract: Nanostructured semiconductor films of SnO2, TiO2 and SnO2/TiO2 have been employed for electrochemically assisted photocatalytic degradation of a textile azo dye naphthol blue black (NBB). The degradation rate is significantly higher for SnO2/TiO2 composite films than SnO2 and TiO2 films alone. An effort has been made to correlate the photoelectrochemical behavior of these films to the rate of photocatalytic degradation of NBB. The enhanced degradation rate of NBB using composite semiconductor films is attributed to increased charge separation in these systems. Photoelectrochemical and photocatalytic degradation experiments carried out in both nitrogen- and oxygen-saturated solutions with an externally applied electrochemical bias provide useful information in optimizing semiconductor concentrations in a composite film.

Genomic divergence during speciation: causes and consequences.

Abstract: Speciation is a fundamental process responsible for the diversity of life. Progress has been made in detecting individual ‘speciation genes’ that cause reproductive isolation. In contrast, until recently, less attention has been given to genome-wide patterns of divergence during speciation. Thus, major questions remain concerning how individual speciation genes are arrayed within the genome, and how this affects speciation. This theme issue is dedicated to exploring this genomic perspective of speciation. Given recent sequencing and computational advances that now allow genomic analyses in most organisms, the goal is to help move the field towards a more integrative approach. This issue draws upon empirical studies in plants and animals, and theoretical work, to review and further document patterns of genomic divergence. In turn, these studies begin to disentangle the role that different processes, such as natural selection, gene flow and recombination rate, play in generating observed patterns. These factors are considered in the context of how genomes diverge as speciation unfolds, from beginning to end. The collective results point to how experimental work is now required, in conjunction with theory and sequencing studies, to move the field from descriptive studies of patterns of divergence towards a predictive framework that tackles the causes and consequences of genome-wide patterns.

Why 'Good' Firms Do Bad Things: The Effects of High Aspirations, High Expectations and Prominence on the Incidence of Corporate Illegality

Abstract: Recent high-profile corporate scandals involving prominent, high-performing firms cast doubt on assertions that the costs of getting caught decrease the likelihood such high performers will act illegally. We explain this paradox by using theories of loss aversion and hubris to examine a sample of S&P 500 manufacturers. Results demonstrate that both performance above internal aspirations and performance above external expectations increase the likelihood of illegal activities. The sample firms’ prominence enhanced the effects of performance above expectations on the likelihood of illegal actions. Prominent and less prominent firms displayed different patterns of behavior when their performance failed to meet aspirations.
