The structural and functional brain networks that support human social networks

Contains fulltext : 195419.pdf (publisher's version ) (Open Access)Social skills rely on a specific set of cognitive processes, raising the possibility that individual differences in social networks are related to differences in specific brain structural and functional networks. Here, we tested this hypothesis with multimodality neuroimaging. With diffusion MRI (DMRI), we showed that differences in structural integrity of particular white matter (WM) tracts, including cingulum bundle, extreme capsule and arcuate fasciculus were associated with an individual’s social network size (SNS). A voxel-based morphology analysis demonstrated correlations between gray matter (GM) volume and SNS in limbic and temporal lobe regions. These structural changes co-occured with functional network differences. As a function of SNS, dorsomedial and dorsolateral prefrontal cortex showed altered resting-state functional connectivity with the default mode network (DMN). Finally, we integrated these three complementary methods, interrogating the relationship between social GM clusters and specific WM and resting-state networks (RSNs). Probabilistic tractography seeded in these GM nodes utilized the SNS-related WM pathways. Further, the spatial and functional overlap between the social GM clusters and the DMN was significantly closer than other control RSNs. These integrative analyses provide convergent evidence of the role of specific circuits in SNS, likely supporting the adaptive behavior necessary for success in extensive social environments.12 p

The why, what, and how of reviewer education: a human capital approach

Reviewing has long been recognized as a critical part of the academic process of knowledge creation, development, and dissemination. However, as evidenced by recent findings from focus groups and an international survey, the relative lack of effective formal training in management PhD programs on how to review is surprising given the impact that reviewing has on the management field. Despite the importance of reviewing to the success of the management field and the careers of those in our profession, many scholars still learn how to review by the inefficient method of trial and error. In response to recent criticisms and calls for the rehabilitation of the review process, the authors discuss why doctoral students need to be educated in order to be effective reviewers, what major topics should be covered in this training, and how certain techniques can be used to educate students while also enhancing their human capital and future career success
