Team identification, trust, and conflict: A mediation model

Purpose — The current study aims to address the relationship between trust, team identification, and team conflict. Specifically, it aims to examine whether trust in peers mediates the relationship between team identification and team conflict. Design/methodology/approach — This is an empirical paper based on two field studies. In Study 1, 241 employees in a US Fortune 500 company distributed in various and mostly R&D teams were surveyed. In Study 2,205 employees in a health care organization in the Midwest were surveyed. Findings — Team identification was related to lower levels of both task conflict and relationship conflict. This relationship, however, is mediated by the employees’ trust in their peers. Research limitations/implications — This finding addresses concerns about the mechanisms by which employee attitudes contribute to work behaviors. Practical implications — This study highlights the importance of cultivating team members’ sense of “we” rather than a sense of “I” in the team context, reinforcing the crucial role of trust in organizational context. Further, by shedding light on the process by which teams come into conflict, our results suggest a means by which managers and organizations can work towards creating optimal levels of conflict in their work teams. Originality/value —As far as it is known, this is the first field study that has examined the mediating role of trust between team identity and team conflict

Genetic studies of body mass index yield new insights for obesity biology

Note: A full list of authors and affiliations appears at the end of the article. Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P 20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.</p
