Willing and able: action-state orientation and the relation between procedural justice and employee cooperation

Existing justice theory explains why fair procedures motivate employees to adopt cooperative goals, but it fails to explain how employees strive towards these goals. We study self-regulatory abilities that underlie goal striving; abilities that should thus affect employees’ display of cooperative behavior in response to procedural justice. Building on action control theory, we argue that employees who display effective self-regulatory strategies (action oriented employees) display relatively strong cooperative behavioral responses to fair procedures. A multisource field study and a laboratory experiment support this prediction. A subsequent experiment addresses the process underlying this effect by explicitly showing that action orientation facilitates attainment of the cooperative goals that people adopt in response to fair procedures, thus facilitating the display of actual cooperative behavior. This goal striving approach better integrates research on the relationship between procedural justice and employee cooperation in the self-regulation and the work motivation literature. It also offers organizations a new perspective on making procedural justice effective in stimulating employee cooperation by suggesting factors that help employees reach their adopted goals

Improved Learning and Memory in Aged Mice Deficient in Amyloid β-Degrading Neutral Endopeptidase

BACKGROUND: Neutral endopeptidase, also known as neprilysin and abbreviated NEP, is considered to be one of the key enzymes in initial human amyloid-beta (Abeta) degradation. The aim of our study was to explore the impact of NEP deficiency on the initial development of dementia-like symptoms in mice. METHODOLOGY/PRINCIPAL FINDINGS: We found that while endogenous Abeta concentrations were elevated in the brains of NEP-knockout mice at all investigated age groups, immunohistochemical analysis using monoclonal antibodies did not detect any Abeta deposits even in old NEP knockout mice. Surprisingly, tests of learning and memory revealed that the ability to learn was not reduced in old NEP-deficient mice but instead had significantly improved, and sustained learning and memory in the aged mice was congruent with improved long-term potentiation (LTP) in brain slices of the hippocampus and lateral amygdala. Our data suggests a beneficial effect of pharmacological inhibition of cerebral NEP on learning and memory in mice due to the accumulation of peptides other than Abeta degradable by NEP. By conducting degradation studies and peptide measurements in the brain of both genotypes, we identified two neuropeptide candidates, glucagon-like peptide 1 and galanin, as first potential candidates to be involved in the improved learning in aged NEP-deficient mice. CONCLUSIONS/SIGNIFICANCE: Thus, the existence of peptides targeted by NEP that improve learning and memory in older individuals may represent a promising avenue for the treatment of neurodegenerative diseases

GeSn heterojunction LEDs on Si substrates

GeSn on Si light-emitting diodes (LEDs) is investigated for different Sn concentrations up to 4.2% and they are compared with an LED made from pure Ge on Si. The LEDs are realized from in-situ doped pin junctions in GeSn on Ge virtual substrates. The device structures are grown with a special ultra-low temperature molecular beam epitaxy process. All LEDs clearly show direct bandgap electroluminescence emission at room temperature. The light intensity of the compressively strained GeSn LEDs increases with higher Sn concentration. The in-plane strain of the LEDs is determined with reciprocal space mapping. The bandgap energies of the emitting GeSn layer are calculated from the emission spectra

Follow the Thing: Data

This research starts its journey from a video that failed to be published during the 2009 uprising in Iran. By following data outside the common trajectories of data circulation in the global North, this paper offers new geographical and data imaginations neglected by the universalised understandings of data and its political economy. Consequently, data’s behaviour as a thing is thoroughly investigated in the “follow the thing tradition” by scrutinising data as a commodity, its meanings and its associations. Using actor-network-theory, the paper highlights data’s open and contested character as well as the breakdowns throughout its journey. Following an uncirculated video via its traces sheds light on data’s agency in evoking different assemblages and spatialities. It also reflects on the epistemological importance of not treating the Southern data as exceptional and calls for a theoretical landscape that does not leave many realities of data out in its homogenised universal narrative
