Effects of team task structure on team climate for innovation and team outcomes

In this cross-sectional study we analyzed, whether team climate for innovation mediates the relationship between team task structure and innovative behavior, job satisfaction, affective organizational commitment, and work stress. 310 employees in 20 work teams of an automotive company participated in this study. 10 teams had been changed from a restrictive to a more self-regulating team model by providing task variety, autonomy, team-specific goals, and feedback in order to increase team effectiveness. Data support the supposed causal chain, although only with respect to team innovative behavior all required effects were statistically significant. Longitudinal designs and larger samples are needed to prove the assumed causal relationships, but results indicate that implementing self-regulating teams might be an effective strategy for improving innovative behavior and thus team and company effectiveness.

Volume hospitalar e outcomes : uma análise a dados administrativos portugueses

RESUMO - Objetivos: Estudos anteriores demonstraram a existência de uma relação inversa entre melhores outcomes e volume hospitalar. Tendo este fenómeno em consideração, o objetivo deste estudo foi analisar esta relação a um nível populacional em Portugal. Métodos: Análise da base de dados Portuguesa dos GDH relativos ao ano financeiro de 2009. Todas as STA e STJ foram contabilizadas e critérios de exclusão determinados, para selecionar duas amostras homogéneas, analisadas por volume hospitalar. O volume hospitalar foi definido em três grupos: HVB, HVM, HVE de acordo com o volume anual de procedimentos efetuado por cada hospital individual durante o período do estudo. Os outcomes avaliados incluíram a mortalidade, presença de pelo menos uma complicação cirúrgica, estadia prolongada assim como a média de dias de internamento. A idade e sexo foram controlados como possíveis fatores de confundimento. Resultados: A investigação principal consistiu na análise de 4615 STA e 5904 STJ. Os resultados indicam que os eventos adversos (mortalidade e complicações cirúrgicas) são pouco comuns nestes procedimentos, produzindo resultados sem significância estatística. A estadia prolongada estabeleceu uma clara e significativa relação inversa com o volume hospitalar. A estadia prolongada foi superior em hospitais de volume baixo (STA OR 2.71; STJ OR 2.17) e hospitais de volume médio (STA OR 1.72; STJ OR 1.73) quando comparados com hospitais de volume elevado. Os dias de internamento médios produziram uma associação semelhante, sendo possível estimar quase oito milhões e meio de euros de custos evitáveis no ano de 2009, em ambos os procedimentos. Conclusões: O volume hospitalar não apresentou relações significativas com a mortalidade e complicações cirúrgicas, devido ao baixo número de eventos adversos registados. Verificou-se, no entanto, uma associação significativa com os dias de internamento e estadia prolongada. As STA e STJ realizadas em hospitais de volume elevado poderão reduzir custos, ao diminuir os dias de internamento.

Referenda outcomes and the influence of polls: A social network feedback process

This paper proposes a model to explain the differences between outcomes of referenda and the voting trends suggested by polls. Two main effects are at stake. First, the evolution of the voters' attitudes is conditional on the public information made available to them. Second, the predisposition toward abstention among individuals within each voting group may be different. Our model describes how these two aspects of decision making may interact, showing how publicly available information may amplify the distinct tendency toward abstention between both groups and thus affect the outcome of the referendum.

Managing talent through developmental job experiences (DJE): The mediating role of DJE between HPWS and employees' outcomes

In the competitive landscape of the 21st century, effectively managing human capital in firms is considered to be a potential source of sustainable performance. Therefore, in this study, we tested the influence of high-performance work systems, as a talent management tool, on employees’ experience of developmental jobs. Then, we tested the mediating effect of such experiences on employees’ engagement, exhaustion, performance and turnover intention. With a sample of 254 employees of a diversity of companies and sectors of activity, our findings demonstrated that high-performance practices increase engagement, via the promotion of developmental experiences of fit, which improves performance and decreases turnover intention. Besides, those practices do not control for the pressure dimension of the developmental job experiences that increases exhaustion and turnover intention despite not worsening performance.

Under the veil of citations

Academics are often ranked on citation counts’, which is considered an adequate proxy for author's quality and reputation. This paper seeks to find what is behind a cited academic / a cited article. We constructed a rich dataset from Portuguese affiliated economists and use zero inflated negative binomial model. This procedure is appropriate for count outcomes, correcting for overdispersion and excess zeros. We also use a fixed effect poisson model to accomodate authors' unobserved heterogeneity. We analyze results in detail comparing with existing literature and making some theoretical considerations around.

Corporate social reponsability strategic corporate social responsability: External and internal outcomes

This study investigates the importance and benefits of having a strategic Corporate Social Responsibility (CSR) program by testing the interrelationships between strategic CSR with three external (reputation, corporate image, and customer loyalty) and four internal (organizational commitment, job satisfaction, performance, and organizational deviance) variables. 269 clients and non-clients along with 190 employees and their direct supervisors completed the survey. Strategic CSR has shown to have a positive impact on all the variables studied with the exception of organizational deviance. Practical implications and suggestions for future research are discussed.

Assessing the role of social networks on migrant labor market outcomes: Evidence from a representative immigrant survey

What role do social networks play in determining migrant labor market outcomes? We examine this question using data from a random sample of 1500 immigrants living in Ireland. We propose a theoretical model formally predicting that immigrants with more contacts have additional access to job offers, and are therefore better able to become employed and choose higher paid jobs. Our empirical analysis confirms these findings, while focusing more generally on the relationship between migrants’ social networks and a variety of labor market outcomes (namely wages, employment, occupational choice and job security), contrary to the literature. We find evidence that having one more contact in the network is associated with an increase of 11pp in the probability of being employed and with an increase of about 100 euros in the average salary. However, our data is not suggestive of a network size effect on occupational choice and job security. Our findings are robust to sample selection and other endogeneity concerns.
