The development of collective efficacy in teams: A multilevel and longitudinal perspective.

The authors developed and tested a longitudinal multilevel model of collective efficacy formation. In 50 self-managing student teams, they investigated the effects of individual-level and team-level factors on observed behaviors and the subsequent development of collective efficacy for mastering a complex team task. Self-efficacy for teamwork, task-relevant knowledge, and collective efficacy predicted individual teamwork behaviors (rated by peers). Aggregated measures of teamwork behavior were related to subsequent collective efficacy, which was significantly related to final team performance.

Deep-level composition variables as predictors of team performance: A meta-analysis.

This study sought to unify the team composition literature by using meta-analytic techniques to estimate the relationships between specified deep-level team composition variables (i.e., personality factors, values, abilities) and team performance. The strength of the team composition variable and team performance relationships was moderated by the study setting (lab or field) and the operationalization of the team composition variable. In lab settings, team minimum and maximum general mental ability and team mean emotional intelligence were related to team performance. Only negligible effects were observed in lab settings for the personality factor and team performance relationships, as well as the value and team performance relationships. In contrast, team minimum agreeableness and team mean conscientiousness, openness to experience, collectivism, and preference for teamwork emerged as strong predictors of team performance in field studies. Results can be used to effectively compose teams in organizations and guide future team composition research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Schools as team-based organizations: A structure-process-outcomes approach.

The present study addressed the issue of teams in schools and the ways in which they contribute to school effectiveness. Specifically, the present research suggested an input (frequency of meetings and functional heterogeneity)-process (interaction processes of exchanging information, learning, motivating, and negotiating)-outcome (team performance and innovation) model for predicting school effectiveness. Two hundred twenty-four school teams (including team coordinators, team members, and school principals) were surveyed. The results indicated that, regarding team innovation, frequency of meetings and functional heterogeneity were positively associated with the 4 interaction processes, which in turn fostered team innovation. However, regarding team performance, the results indicated that only frequency of meetings was positively associated with the interaction process of exchanging information, which in turn enhanced team performance. The findings serve to draw important theoretical and practical conclusions as to the best ways to structure schools and to improve their interaction processes for the enhancement of team performance and team innovation.

Cooperative outcome interdependence, task reflexivity, and team effectiveness: A motivated information processing perspective.

A motivated information processing perspective (C. K. W. De Dreu & P. J. D. Carnevale, 2003; see also V. B. Hinsz, R. S. Tindale, & D. A. Vollrath, 1997) was used to predict that perceived cooperative outcome interdependence interacts with team-level reflexivity to predict information sharing, learning, and team effectiveness. A cross-sectional field study involving management and cross-functional teams (N = 46) performing nonroutine, complex tasks corroborated predictions: The more team members perceived cooperative outcome interdependence, the better they shared information, the more they learned and the more effective they were, especially when task reflexivity was high. When task reflexivity was low, no significant relationship was found between cooperative outcome interdependence and team processes and performance. The author concludes that the motivated information processing perspective is valid outside the confines of the laboratory and can be extended toward teamwork in organizations.

A Software-Hardware Co-Implementation of MPEG-4 Advanced Video Coding (AVC) Decoder with Block Level Pipelining

We present a baseline MPEG-4 Advanced Video Coding (AVC) decoder based on the methodology of joint optimization of software and hardware. The software is first optimized with algorithm improvements for frame buffer management, boundary padding, content-aware inverse transform and context-based entropy decoding. The overall decoding throughput is further enhanced by pipelining the software and the dedicated hardware at macroblock level. The decoder is partitioned into the software and hardware modules according to the target frame rate and complexity profiles. The hardware acceleration modules include motion compensation, inverse transform and loop filtering. By comparing the optimized decoder with the committee reference decoder of Joint Video Team (JVT), the experimental results show improvement on the decoding throughput by 7 to 8 times. On an ARM966 board, the optimized software without hardware acceleration can achieve a decoding rate up to 5.9 frames per second (fps) for QCIF video source. The overall throughput is improved by another 27% to 7.4 fps on the average and up to 11.5 fps for slow motion video sequences. Finally, we provide a theoretical analysis of the ideal performance of the proposed decoder.Shih-Hao Wang was born in Tainan, Taiwan, R.O.C. in 1977.

D and z Values of Salmonella, Listeria innocua, and Listeria monocytogenes in Fully Cooked Poultry Products

: The D and z values of Salmonella, Listeria innocua, and Listeria monocytogenes were obtained for different ready‐to‐eat poultry products, including chicken, turkey, and duck. The D values of Salmonella, L. innocua, and L. monocytogenes were 151.5 to 0.1 min at 55 to 70°C, and the z values of Salmonella, L. innocua, and L. monocytogenes were 4.9 to 7.0 °C. Significant differences were found for the heat resistance of Salmonella, L. innocua, and L. monocytogenes among turkey, duck, and chicken products, indicating that the kinetic values of a certain pathogen in a specific product should be used for determining process lethality in fully cooked and vacuum‐packaged poultry products during post‐cook heat treatments.
