How do supply chain management and information systems practices influence operational performance?:Evidence from emerging country SMEs

This study first provides a comparative analysis of the impact of supply chain management (SCM) and information systems (IS) practices on operational performance (OPER) of small- and medium-sized enterprises (SMEs) operating in two neighbouring emerging country markets of Turkey and Bulgaria. Then, we investigate moderating effects of both SCM–IS-linked enablers and inhibitors on the links between SCM and IS practices and OPER of SMEs. To this end, we first empirically identify the underlying dimensions of SCM and IS practices, and SCM–IS-related enabling and inhibiting factors. Second, a series of regression analyses are undertaken to estimate the impact of the study's constructs on OPER of SMEs. The results are discussed comparatively within the contexts of both Turkish and Bulgarian SMEs and beyond. The study makes a significant contribution to the extant literature through obtaining and analysing cross-national survey data of SCM and IS practices in emerging country markets

Relationship between sport website quality and consumption intentions: Application of a bifactor model

This study investigated the cognitive structure of sport website quality constructs by comparing a bifactor model (a.k.a., a general-specific model) to a second-order model. The models are two alternative approaches for representing general constructs consisting of several highly related but distinct domains. In addition, the link between sport website quality and the revisitation and media consumption intentions was empirically tested. Data (N=272) were collected through an online survey, and the majority of respondents were men (66.3%) between 21 and 30 years old (63.0%). The bifactor and second-order models of sport website quality were also assessed and compared, and a simultaneous equation modeling analysis was used. The bifactor model fit the data significantly better than the second-order model, indicating that the five sub-constructs revealed both the specific dimensions of sport website quality and the holistic nature of sport website quality. Results from the simultaneous equation model indicated that sport website quality explained 70.2% of the variance in revisitation and 58.7% of intention to consume sports media. © The Author(s) 2016

Retesting personality in employee selection: Implications of the context, sample, and setting

The present study sought to assess when and how actual job applicants change their responses when filling out an unproctored personality selection assessment for a second time. It was predicted feedback would be a key contextual motivator associated with how much applicants change their answers during the second administration. Mediation results showed that individuals receiving feedback that showed a low score on the personality assessment was the reason they did not get the job were more likely to employ faking response strategies in the second testing session, predicting the highest change in scores between the first and second testing sessions. Individuals receiving no feedback and those not experimentally motivated to fake (i.e., a comparison group of students) showed less change in responses across administrations. © Psychological Reports 2013

Attentional bias for negative expressions depends on previous target location: replicable effect but unreliable measures

Observability of threat-related spatial attentional biases may require previous-trial responses associated with threat-related locations. This carryover effect might affect reliability and correlations. In Study 1, a diagonalized Visual Probe Task was completed online (N=131) with colour, anger, fear and disgust stimuli, with questionnaires on aggression, anxiety, depression and impulsivity. Bias towards negative stimuli was found only following previous targets on the negative location. Study 2 aimed to test an interpretation in terms of cue-evoked attention. Task variants were completed (N=101) with and without removal of the cue when targets appeared. Anger and disgust stimuli and aggression, anxiety and depression scales were used. Carryover was replicated with no interaction with cue offset. Over both tasks, reliability was low and no robust correlations with questionnaires were found. Carryover thus determined whether attentional bias to negative facial expressions was observed, but analyses taking this into account did not improve reliability or reveal correlations

Assessing public leadership styles for innovation:A comparison of Copenhagen, Rotterdam and Barcelona

This article explores which leadership qualities public managers regard as important for public innovation. It is based on a survey of 365 senior public managers in Copenhagen, Rotterdam and Barcelona. Five perspectives on leadership were identified and tested using a number of items. Some of these proved to be more robust than others. Analysis of the three cities reveals a nuanced set of leadership styles, which include a transformational style, and one that is more dedicated to motivating employees, risk-taking and including others in decision-making. This suggests the need for more research on leadership and public-sector innovation

Coupling biochemistry and mechanics in cell adhesion: a model for inhomogeneous stress fiber contraction

Biochemistry and mechanics are closely coupled in cell adhesion. At sites of cell-matrix adhesion, mechanical force triggers signaling through the Rho-pathway, which leads to structural reinforcement and increased contractility in the actin cytoskeleton. The resulting force acts back to the sites of adhesion, resulting in a positive feedback loop for mature adhesion. Here we model this biochemical-mechanical feedback loop for the special case when the actin cytoskeleton is organized in stress fibers, which are contractile bundles of actin filaments. Activation of myosin II molecular motors through the Rho-pathway is described by a system of reaction-diffusion equations, which are coupled into a viscoelastic model for a contractile actin bundle. We find strong spatial gradients in the activation of contractility and in the corresponding deformation pattern of the stress fiber, in good agreement with experimental findings.Comment: Revtex, 35 pages, 13 Postscript figures included, in press with New Journal of Physics, Special Issue on The Physics of the Cytoskeleto

Energetic increases lead to niche packing in deep-sea wood falls

Mechanisms leading to variation in diversity over energetic gradients continue to challenge ecologists. Changes in diversity may reflect the environmental capacity to support species' coexistence through increased niche packing or niche space expansion. Current ecological theory predicts that increases in energy may lead to both scenarios but not their relative strengths. We use experimental deep-sea, wood-fall communities, where energy supply can be controlled, to test for the importance of niche expansion and packing in functional space over an energetic gradient. Invertebrate communities were identified and counted from 16 Acacia sp. logs ranging in size from 0.6 to 20.6 kg in mass (corresponding to energy availability) deployed at 3203 m in the Pacific Ocean for 5 years. We use four fundamental energetic species-level functional traits—food source, trophic category, motility and tiering—to characterize species niches. Increases in energy on wood falls lead to increases in species richness. This higher species richness resulted from a substantial increase in mean niche overlap, suggesting that increases in energy may afford reduced competition

Effects of social capital on operational performance: impacts of servitisation

Studies on servitisation have largely overlooked the roles of social capital with suppliers and knowledge management. We propose a moderated mediation model to investigate the impacts of servitisation on the mechanisms through which social capital with suppliers improves operational performance. The hypotheses are empirically tested using structural equation modelling and data collected from 276 manufacturing firms in China. The results show that social capital improves operational performance both directly and indirectly through knowledge management, and the relationships are influenced by servitisation. In particular, social capital improves operational performance directly and indirectly through knowledge combination in servitised firms, whereas social capital only improves operational performance indirectly through knowledge acquisition in traditional manufacturers. The findings contribute to the literature by revealing that the effects of social capital with suppliers on operational performance are partially mediated by knowledge acquisition and knowledge combination and the mediation effects are moderated by servitisation, and by providing insights into how to design purchasing and production systems to profit from servitisation

Clustering Attitudes and Behaviors of High/Low Involvement Grocery Shopper

The purpose of this exploratory and quantitative study was to examine the attitudes and behaviors of 14,807 grocery shop- pers. These respondents across the US were asked to answer attitudinal, behavioral, and demographic related questions. Shoppers were profiled by analyzing their responses to 16 relevant attitudinal and behavioral questions. A cluster analysis was performed followed by a discriminant analysis to deter- mine attitudinal and behavioral variables explaining cluster membership. A cross-tabulation analysis assessed demo- graphic variables that correlated with cluster membership. Two clusters were identified: high and low involvement grocery shoppers. In an event that has long been perceived as low involvement, a large percentage (53%) can be categorized as high involvement grocery shoppers. These shoppers tend to be younger. They were more likely to enjoy the hunt of finding products/deals, seek the advice of others and perceive that the products they buy reflect upon them. Grocery stores have a significant opportunity to target this high involvement shop- per. Grocery stores will need to create an integrative, engaging online and in-store experience to attract high involvement shoppers and ultimately increase store loyalty. The results of this research has significant communication, branding and digital marketing implications

Evaluating the educational value of simulation games: Learners’ perspective

Simulation games (SG) offer great opportunities for students to learn and experience real-world business decisions in a risk-free learning environment. However, the impact of using SG on educational outcomes is not fully understood. Drawing on experiential learning theory, we develop a conceptual model to examine students’ perceptions of the educational values generated from a SG adopted in a postgraduate program at a UK business school. The study gathered data from 120 students by using survey data and qualitative data from students’ reflective reports. Results show that SG have positive impact on students’ conceptual understanding, skills development and affective evaluation of their learning experience. The paper discusses the findings and its implications for educational practitioners and offers directions for future research
