A transactional stress and coping perspective on expatriation : new insights on the roles of age, gender and expatriate type

Purpose This work sheds new light on the roles of gender, age and expatriation type—self-initiated expatriate (SIE) vs. assigned expatriate (AE)—by applying the transactional theory of stress and coping (and a validated measurement tool) to the expatriation experience. Design/methodology/approach Based on quantitative data from 448 expatriates, the authors examined the coping mechanisms (cognitions and actions) employed by senior and younger expatriates, females and males and SIE and AEs when they face hardships while working abroad. Findings Younger expatriates display less active problem-solving coping, planning, and restraint and consume more alcohol and drugs. Female expatriates express their emotions and use social support more than their male counterparts. SIEs rely on emotional social support more than AEs. Practical implications Recognizing that individual repertoires of responses to expatriate challenges are bounded by personal characteristics—such as age, gender, and expatriation type—should improve efforts to support expatriates. This research suggests that expatriate support should be tailored. It offers indications on who needs what. Originality/value This work provides a fresh perspective and new insights into classic topics (age, gender, and expatriation type). Individuals react differently abroad. They have different resources and face different demands (to a certain extent) that lead to different coping reactions. Older people manage their emotions better, and female expatriates and SIEs gather and use support; these abilities are assets abroad.© Olivier Wurtz. Published by Emerald Publishing Limited.

Expatriation, alcohol and drugs : antecedents and consequences of substance use in expatriation

Purpose – Expatriation is known to be stressful. The present study examines stress as an antecedent of substance use during expatriation and related effects on expatriates' work adjustment. Moreover, the study sheds light on individual-level moderators (i.e. gender and prior international experience) and organizational-level moderators (i.e. organizational social support) that might condition the stress substance use link. Design/methodology/approach - This work adopts a quantitative survey approach. It is based on two studies, one of 205 expatriates and one of 96 expatriate–supervisor dyads. The data were collected through personal networks and with the help of multinational companies. Findings - This research shows that stress at a medium to high-level increases substance use among male expatriates, but not among female expatriates. Expatriates with substantial prior international experience were identified as being more prone to react to stress by resorting to substance use. It also provides evidence that substance use to aid coping harms professional adjustment. Moreover, some implications relating to professional adjustment are discussed. Research limitations/implications - Substance use was self-reported; this may have deterred users from accurately reporting their consumption levels. Moreover, convenience samples have been used. Preventive actions limiting substance use, such as well-being programs, could be sponsored by local human resources managers in order to limit this phenomenon. Originality/value - This work is one of the first to analyze substance use among expatriates. It shows that some expatriates are more at risk than others of resorting to such use to cope with the hardships of expatriation.fi=vertaisarvioitu|en=peerReviewed

International Management as Management of Diversity : Reconceptualizing Distance as Diversity

Despite the importance of distance in international business and management research, the theoretical foundation for the concept and the underlying causal mechanisms are subject to shortcomings. We propose reinvigorating the study of distance through a diversity lens. We draw on research on diversity and develop a theoretical framework that distinguishes types of diversity (separation, variety, and disparity) at three levels (institutional, organizational, and individual). We show how this framework allows scholars to extend their analysis of distance, revisit important questions, and explore new issues. We discuss the theoretical and empirical implications of our diversity lens for the international business and management community.© 2021 The Authors.

A transactional stress theory of global work demands : A challenge, hindrance, or both?

We integrate research on global work demands (Shaffer et al., 2012) with transactional stress theory to examine both the harmful and beneficial effects of three global work demands—international travel, cognitive flexibility, and nonwork disruption—for employees engaged in global work. We propose that global work demands have indirect, and conditional, effects on burnout and work-to-family conflict (WFC), as well as thriving and work–family enrichment, through employees’ appraisals that their global work is both hindering and challenging, respectively. We tested the hypotheses with a matched sample of 229 global employees and their spouses. We found that cognitive flexibility demands are related to harmful and beneficial outcomes: It increases WFC through hindrance appraisals of the global work, but also increases thriving through challenge appraisals. In comparison, international travel demands have only beneficial outcomes, such that it positively related to employee thriving through challenge appraisals, but only among employees working in jobs that have fewer nonwork disruption demands. Finally, nonwork disruption demands had only harmful effects in that it positively related to burnout and WFC through hindrance appraisals. Exploratory analyses also revealed that nonwork disruption demands negatively related to employee thriving, through challenge appraisals, when employees experienced lower levels of cognitive flexibility demands. These findings contribute to our understanding of how employees may react to their global work demands and to the transactional theory of stress by providing a more nuanced understanding of when and why job demands contribute to appraisals that work is hindering and/or challenging.© 2022, American Psychological Association.

Ultrafast Optical Modulation of Second- and Third-Harmonic Generation from Cut-Disk-Based Metasurfaces

We design and fabricate a metasurface composed of gold cut-disk resonators that exhibits a strong coherent nonlinear response. We experimentally demonstrate all-optical modulation of both second- and third-harmonic signals on a subpicosecond time scale. Pump−probe experiments and numerical models show that the observed effects are due to the ultrafast response of the electronic excitations in the metal under external illumination. These effects pave the way for the development of novel active nonlinear metasurfaces with controllable and switchable coherent nonlinear response

Pituitary Adenylate Cyclase Activating Peptide (1-38) and its analog (Acetyl-[Ala15, Ala20] PACAP 38-polyamide) reverse methacholine airway hyperresponsiveness in rats
