This research investigated the link between ethical leadership and performance using data from the People’s Republic of China. Consistent with social exchange, social learning, and social identity theories, we examined leader–member exchange (LMX), self-efficacy, and organizational identification as mediators of the ethical leadership to performance relationship. Results from 72 supervisors and 201 immediate direct reports revealed that ethical leadership was positively and significantly related to employee performance as rated by their immediate supervisors and that this relationship was fully mediated by LMX, self-efficacy, and organizational identification, controlling for procedural fairness. We discuss implications of our findings for theory and practice.

Impaired strength adversely influences an older person's ability to perform activities of daily living. A cross-sectional study of 117 independently living men and women (age = 73.4 9.4 year; body mass index (BMI) = 27.6 4.8 kg/m2) aimed to assess the association between body composition and: (1) upper body strength (handgrip strength, HGS); (2) lower extremity performance (timed up and go (TUG) and sit to stand test (STS)); and (3) endurance (6-minute walk (SMWT). Body composition (% fat; lean body mass (LBM)) was assessed using bioelectrical impedance. Habitual physical activity was measured using the Minnesota Leisure Time Physical Activity Questionnaire …

Alternate cycling of sludge in aerobic, anoxic, and anaerobic regimes is a promising strategy that can reduce the sludge yield of conventional activated sludge (CAS) by up to 50% with potentially lower capital and operating cost than physical- and/or chemical-based sludge minimisation techniques. The mechanisms responsible for reducing sludge yield include alterations to cellular metabolism and feeding behaviour (metabolic uncoupling, feasting/fasting, and endogenous decay), biological floc destruction, and predation on bacteria by higher organisms. Though discrepancies across various studies are recognisable, it is apparent that sludge retention time, oxygen-reduction potential of the anaerobic tank, temperature, sludge return ratio and loading …

Key Takeaways • Without a valid, reliable way to collect data from various library and enterprise systems, it's difficult to quantitatively assert how a library adds value. • University of Wollongong Library developed the Library Cube, a tailored database and reporting function that joins library usage data with student data, including demographic and academic performance information. • Analysis of the resulting data reveals a strong correlation between students' grades and use of information resources the library provides.
Organizational Performance In Services, Rosemary Batt, Virginia Doellgast
Organizational Performance In Services, Rosemary Batt, Virginia Doellgast

The question of performance in service activities and occupations is important for several reasons. First, over two-thirds of employment in advanced economies is in service activities. Second, productivity growth in services is historically low, lagging far behind manufacturing, and as a result, wages in production-level service jobs remain low. In addition, labor costs in service activities are often over 50% of total costs, whereas in manufacturing they have fallen to less than 25% of costs. This raises the question of whether management practices that have improved performance in manufacturing, such as investment in the skills and training of the workforce, …
A Novel Integrated Model To Measure Supplier Performance Considering Qualitative And Quantitative Criteria Used In The Supplier Selection Process, Alptekin Ulutas, Senevi Kiridena, Peter Gibson, Nagesh Shukla

Supplier evaluation has become a significant topic over the past few decades, as companies have become more outsourced oriented. However, previous research on this topic has not paid adequate attention to the limitations associated with the availability of accurate and reliable data relating to the performance of potential suppliers. In an attempt to address this issue, this paper proposes a novel supplier evaluation model that can handle imprecise quantitative and qualitative data. Additionally, Decision Maker's judgement regarding both qualitative and quantitative criteria are incorporated into this model so that a more comprehensive and realistic assessment of supplier performance can be …
Performance Of Adjustable Speed Drives Subject To Regular Voltage Fluctuations, Kun Zhao, Philip Ciufo, Sarath Perera
Performance Of Adjustable Speed Drives Subject To Regular Voltage Fluctuations, Kun Zhao, Philip Ciufo, Sarath Perera
Dr Philip Ciufo
The impact of power quality disturbances on customer equipment has been a topic of interest to equipment manufacturers, electricity utilities, customers and to those involved in the development of electromagnetic compatibility standards. Recently, a new interest has developed in the possible impact of voltage fluctuations on customer equipment because of suggestions to relax voltage fluctuation limits and hence the flicker limits in power systems. With a view to contribute to this understanding, this paper investigates the performance of an adjustable speed drive (ASD) when subjected to sinusoidal regular voltage fluctuations. When the ASD is operating in open loop mode, the …
Collective Failure: The Emergence, Consequences, And Management Of Errors In Teams, Bradford S. Bell, Steve W. J. Kozlowski
Collective Failure: The Emergence, Consequences, And Management Of Errors In Teams, Bradford S. Bell, Steve W. J. Kozlowski
Bradford S Bell
The goal of the current chapter is to examine the emergence, consequences, and management of errors in teams. We begin by discussing the origin and emergence of errors in teams. We argue that errors in teams can originate at both the individual and collective level and suggest this distinction is important because it has implications for how errors propagate within a team. We then consider the paradoxical effects of errors on team performance and team learning. This discussion highlights the importance of error management in teams so that errors can prompt learning while at the same time mitigating their negative …

With the increasing emphasis on work teams as the primary architecture of organizational structure, scholars have begun to focus attention on team learning, the processes that support it, and the important outcomes that depend on it. Although the literature addressing learning in teams is broad, it is also messy and fraught with conceptual confusion. This chapter presents a theoretical integration and review. The goal is to organize theory and research on team learning, identify actionable frameworks and findings, and emphasize promising targets for future research. We emphasize three theoretical foci in our examination of team learning, treating it as multilevel …
