Impact of spousal work restrictions on expatriates' work life and overall life satisfaction

Our understanding of the challenges and the broader role of spouses of expatriates is extremely limited. This study examined the impact of spousal work restrictions on expatriates' work life and overall life satisfaction using qualitative and quantitative analyses based on data from a sample of 409 Indian Information Technology professionals working in USA. Furthermore, hypothesised conditional process model (tested with PROCESS analysis tool) was supported, showing that spousal work restrictions created complications in personal lives of expatriates, which interfered with work lives resulting in lower overall life satisfaction. We identified six core classes of challenges faced by spouses of expatriates: wasted skills, financial issues, boredom, social isolation, quality time and domestic tension. Our mixed method approach also helps to provide a more comprehensive picture of these complications. This study may help organisational leaders and policy makers to more fully consider the implications of visa-related policy changes on expatriate families.     

Pharmacological manipulations of brain catecholamines and the aggressive behavior induced by marihuana in REM-sleep-deprived rats

A marihuana extract, apomorphine, and amphetamine provoked in rats previously deprived of REM sleep for 96 hr an upright position with the animals pawing each other as in fighting. Nondeprived rats injected with the drugs did not show this aggressive behavior. The marihuana-treated animals also bit vigorously a rod introduced into the cage, a fact not observed with the apomorphine-treated rats. These data suggest that the marihuana aggressiveness could at least partially be mediated through the brain catecholamines. Haloperidol, chlorpromazine, α-methyl-p-tyrosine, and reserpine decreased the marihuana aggressiveness of the deprived rats. Increase of dopamine concentration by previous treatment with Dopa potentiated aggressiveness. Blockade of norepinephrine synthesis by FLA-63 was ineffective in reducing marihuana aggressiveness in the REM-sleep-deprived rats. Actually, in these animals aggressiveness appreared even without the marihuana injection. Phenoxybenzamine partially blocked marihuana aggressiveness but also severely depressed the rats. However, 20 mg/kg alone succeeded in provoking aggressiveness in the deprived rats. It is suggested that in rats with neural excitability heightened by previous REM-sleep deprivation dopamine facilitates aggressive behavior, an effect inhibited by porepinephrine. This hypothesis would imply that marihuana induces aggressiveness in REM-sleep-deprived rats by inhibiting, through an as yet unknown mechanism, the central norepinephrine system.     

The development of organized rehearsal

The purpose of this research was to evaluate the development or organization strategies in rehearsal processes. First-grade (age 7 years), third-grade (age 9 years), and fifth-grade (age 11 years) children were exposed to a memory task which involved multiple overt rehearsal and recall phases. The children were either free to rehearse any words from a taxonomically structured list or they were taught to rehearse in categories. The recall phase was either free or categorically cued. The number of repetitions in rehearsal increased only as a function of age. All of the independent variables facilitated the amount of organized rehearsal and the amount of retention. Children at all ages were able to maximize the relative amount of organized rehearsal when rehearsal was cued. The correlational analysis of the dependent variables indicated that for young children the quantity of rehearsal was linked to retention, but for older children the quality of rehearsal was related to retention. The results were interpreted as demonstrating the bases for production inefficiencies.     

Self-reported likelihood of sexually aggressive behavior: Attitudinal versus sexual explanations

The present study compared the relative effectiveness of sexuality variables versus attitudes hypothesized to be rape-supportive in the prediction of “likelihood to rape” (LR) and “likelihood to use sexual force” (LF) measures. This research was guided by the suggestion that understanding the variables which underlie LR and LF may shed light on the factors which cause some men to actually commit acts of violence against women. The results were inconsistent with viewing rape as primarily caused by sexual frustration or sexual maladjustment, since sexuality variables were generally not predictive of LF or LR. In contrast, a variety of rape-supportive attitudes and beliefs such as blaming the victim for her rape or viewing sexual violence as sexually arousing to women were successful predictors of both LF and LR. These data were interpreted as supporting theories of rape which consider cultural, socially transmitted attitudes about women and rape to be psychological releasers for sexual aggression. The findings also supported the notion of an “aggression toward women” continuum, rather than a conceptualization of rape as a discrete, isolated phenomenon with its own determinants.     

Testing motivational and self-regulatory mechanisms of action on device-measured physical activity in the context of a weight loss maintenance digital intervention: A secondary analysis of the NoHoW trial

BackgroundTo date, few digital behavior change interventions for weight loss maintenance focusing on long-term physical activity promotion have used a sound intervention design grounded on a logic model underpinned by behavior change theories. The current study is a secondary analysis of the weight loss maintenance NoHoW trial and investigated putative mediators of device-measured long-term physical activity levels (six to 12 months) in the context of a digital intervention.MethodsA subsample of 766 participants (Age = 46.2 ± 11.4 years; 69.1% female; original NoHoW sample: 1627 participants) completed all questionnaires on motivational and self-regulatory variables and had all device-measured physical activity data available for zero, six and 12 months. We examined the direct and indirect effects of Virtual Care Climate on post intervention changes in moderate-to-vigorous physical activity and number of steps (six to 12 months) through changes in the theory-driven motivational and self-regulatory mechanisms of action during the intervention period (zero to six months), as conceptualized in the logic model.ResultsModel 1 tested the mediation processes on Steps and presented a poor fit to the data. Model 2 tested mediation processes on moderate-to-vigorous physical activity and presented poor fit to the data. Simplified models were also tested considering the autonomous motivation and the controlled motivation variables independently. These changes yielded good results and both models presented very good fit to the data for both outcome variables. Percentage of explained variance was negligible for all models. No direct or indirect effects were found from Virtual Care Climate to long term change in outcomes. Indirect effects occurred only between the sequential paths of the theory-driven mediators.ConclusionThis was one of the first attempts to test a serial mediation model considering psychological mechanisms of change and device-measured physical activity in a 12-month longitudinal trial. The model explained a small proportion of variance in post intervention changes in physical activity. We found different pathways of influence on theory-driven motivational and self-regulatory mechanisms but limited evidence that these constructs impacted on actual behavior change. New approaches to test these relationships are needed. Challenges and several alternatives are discussed.Trial registrationISRCTN Registry, ISRCTN88405328.

CULTURAL MODELS OF INFANT EMOTIONS AND NEEDS AMONG THE GAMO PEOPLE OF SOUTHERN ETHIOPIA

How mothers perceive their infants’ emotions and their subsequent responses are influenced by cultural values and beliefs. Mothers who live in particularly harsh environments may have perceptions about their infants’ emotions that reflect not only cultural values but also constraints of the environment. In this qualitative study, 29 Gamo mothers living in rural Ethiopia were interviewed about perceptions of their infants’ emotions, how they felt about these emotions, and what they believed their infants needed in response. Through constant comparative analysis and thematic coding, several patterns emerged in mothers’ perceptions about their infants’ emotions and what constituted appropriate responses. Mothers said that their infants’ negative emotions were possibly related to illness and that appropriate responses were focused mostly on breastfeeding, complementary food, and needing to be held. Mothers also discussed their work demands and how they conflicted with their desire to respond to their infants; however, many mothers said that they relied on their older children to help. Mothers’ responses were centered on a parenting strategy aimed at promoting infant health and survival, which is consistent with research on parents living in rural environments who subsist by farming and have relatively high risk for infant mortality.     

Let's Talk About Race: Evaluating a College Interracial Discussion Group on Race

The authors evaluate Dialogues on Race, an interracial group intervention in which undergraduate student facilitators led conversations about race with their peers. The evaluation process is described, including developing collaborative relationships, identifying program goals, selecting measures, and analyzing and presenting results. The authors discuss lessons learned about evaluating an interracial dialogue intervention that did not originally include researchers in the hope that this examination will encourage others to evaluate similar campus interventions. Diálogos sobre Raza es una intervención de grupo interracial en la que estudiantes universitarios moderaron conversaciones sobre raza con sus compañeros. Se describe el proceso de evaluación, incluyendo el desarrollo de relaciones de colaboración, la identificación de objetivos del programa, la selección de medidas, y el análisis y presentación de los resultados. Los autores discuten las lecciones aprendidas sobre la evaluación de una intervención interracial dialogada que en principio no incluyó a investigadores con la esperanza de que este examen animará a otros a evaluar intervenciones similares en sus campus.
