Vector magnetic field microscopy using nitrogen vacancy centers in diamond

The localized spin triplet ground state of a nitrogen vacancy (NV) center in diamond can be used in atomic-scale detection of local magnetic fields. Here we present a technique using these defects in diamond to image fields around magnetic structures. We extract the local magnetic field vector by probing resonant transitions of the four fixed tetrahedral NV orientations. In combination with confocal microscopy techniques, we construct a 2-dimensional image of the local magnetic field vectors. Measurements are done in external fields less than 50 G and under ambient conditions.Comment: 9 pages, 3 figure

A cross-national study on the antecedents of work–life balance from the fit and balance perspective

Drawing on the perceived work–family fit and balance perspective, this study investigates demands and resources as antecedents of work–life balance (WLB) across four countries (New Zealand, France, Italy and Spain), so as to provide empirical cross-national evidence. Using structural equation modelling analysis on a sample of 870 full time employees, we found that work demands, hours worked and family demands were negatively related to WLB, while job autonomy and supervisor support were positively related to WLB. We also found evidence that resources (job autonomy and supervisor support) moderated the relationships between demands and work–life balance, with high resources consistently buffering any detrimental influence of demands on WLB. Furthermore, our study identified additional predictors of WLB that were unique to some national contexts. For example, in France and Italy, overtime hours worked were negatively associated with WLB, while parental status was positively associated with WLB. Overall, the implications for theory and practice are discussed.Peer ReviewedPostprint (author's final draft

Location, location, location: contextualizing workplace commitment

The purpose of the present commentary is to discuss the nature and correlates of workplace commitment across cultures. We asked six organizational behavior scholars, who are intimately familiar with Brazil, China, Denmark, Germany, or Israel as their country of origin or extended residence, to “contextualize” workplace commitment. They did so by explicating institutional and cultural characteristics of their context on the emergence, meaning, and evolution of commitment by reference to their own research and extant local research. Their responses not only supported the utility of three-component model of commitment but also revealed the differential salience of various commitment constructs (e.g., components and foci of commitment) as well as possible contextual moderators on the development and outcomes of commitment. The commentators also described changes including the growing prevalence of multicultural workforces within national borders and changes in employment relationships and cultural values in their national contexts and considered future research directions in culture and commitment research

Applicant perspectives during selection

We provide a comprehensive but critical review of research on applicant reactions to selection procedures published since 2000 (n = 145), when the last major review article on applicant reactions appeared in the Journal of Management. We start by addressing the main criticisms levied against the field to determine whether applicant reactions matter to individuals and employers (“So what?”). This is followed by a consideration of “What’s new?” by conducting a comprehensive and detailed review of applicant reaction research centered upon four areas of growth: expansion of the theoretical lens, incorporation of new technology in the selection arena, internationalization of applicant reactions research, and emerging boundary conditions. Our final section focuses on “Where to next?” and offers an updated and integrated conceptual model of applicant reactions, four key challenges, and eight specific future research questions. Our conclusion is that the field demonstrates stronger research designs, with studies incorporating greater control, broader constructs, and multiple time points. There is also solid evidence that applicant reactions have significant and meaningful effects on attitudes, intentions, and behaviors. At the same time, we identify some remaining gaps in the literature and a number of critical questions that remain to be explored, particularly in light of technological and societal changes

The meaning of my feelings depends on who I am: work-related identifications shape emotion effects in organizations

Theory and research on affect in organizations has mostly approached emotions from a valence perspective, suggesting that positive emotions lead to positive outcomes and negative emotions to negative outcomes for organizations. We propose that cognition resulting from emotional experiences at work cannot be assumed based on emotion valence alone. Instead, building on appraisal theory and social identity theory, we propose that individual responses to discrete emotions in organizations are shaped by, and thus depend on, work-related identifications. We elaborate on this proposition specifically with respect to turnover intentions, theorizing how three discrete emotions - anger, guilt, and pride - differentially affect turnover intentions, depending on two work-related identifications - organizational and occupational identification. A longitudinal study involving 135 pilot instructors reporting emotions, work-related identifications, and turnover intentions over the course of one year provides general support for our proposition. Our theory and findings advance emotion and identity theories by explaining how the effects of emotions are dependent on the psychological context in which they are experienced

All you need is ... resources : the effects of justice and support on burnout and turnover

We propose and test a comprehensive model of burnout, as influenced by justice and support, and as it impacts the turnover process. Deriving our conceptual model from conservation of resources theory, augmented by several domain-specific theories, we investigate three forms of justice (distributive, procedural, and interactional justice) and two sources of support (from organizations and supervisors) as they influence the development of three dimensions of burnout (emotional exhaustion, depersonalization, and diminished accomplishment) and subsequent forms of attitudinal withdrawal (organizational commitment and turnover intentions) and behavioral withdrawal (turnover). In a study of 343 social workers, our theoretical path model was well-supported, providing increased understanding of the distinct roles of each form of justice and support in the development of burnout and the subsequent turnover process. Theoretical contributions and implications in the areas of justice, burnout, and turnover are discussed
