The Influence of an Acute Bout of Whole Body Vibration on Human Postural Control Responses

The use of vibrating platforms has become increasingly available, and popular at sports and rehabilitation institutes. Given the discrepancies in the literature regarding whole body vibration (WBV) and human reflexive responses, the purpose of this study was to examine the acute effects of WBV on postural response latencies, as well as associated electromyography measures of the lower extremities during balance perturbations. Reflexive responses during backward and forward balance perturbations were examined before, after, and 10 min after a bout of WBV. The findings suggest that following an acute bout of whole body vibration, muscle activity of the lower extremities is decreased during a reflexive response to an unexpected perturbation, and may be associated with faster reaction time.     

职业污名与离职倾向：牵连家人污名与家庭卷入的作用

职业污名对从业者的工作态度和工作行为有着重要影响。以往研究从个体职业身份的视角解释职业污名的作用, 忽略了从业者个体身份认同的多重属性。本研究基于身份边界理论, 提出职业污名会通过牵连家人污名这一机制影响从业者的离职倾向。另外, 这一机制的强弱取决于个体的家庭卷入程度。本研究通过对分属不同职业的384名从业者的3轮问卷调研发现, 家庭卷入调节了牵连家人污名在职业污名与离职倾向之间的中介作用。当个体的家庭卷入水平高时, 这一中介作用更强; 家庭卷入水平低时, 该中介作用更弱。本研究在理论上提出并检验了职业污名影响的新机制, 同时对实际管理工作提出了建议。     

Resign or carry-on? District and principal leadership as drivers of change in teacher turnover intentions during the COVID-19 crisis: A latent growth model examination

During the COVID-19 pandemic, teachers in the United States, an already at-risk occupation group, experienced new work-related stressors, safety concerns, and work-life challenges, magnifying on-going retention concerns. Integrating the crisis management literature with the unfolding model of turnover, we theorize that leader actions trigger initial employee responses but also set the stage for on-going crisis response that influence changes in teachers' turnover intentions. We apply latent growth curve modelling to test our hypotheses based on a sample of 617 K-12 teachers using nine waves of data, including a baseline survey at the start of the 2020–2021 school year and eight follow-up surveys (2-week lags) through the Fall 2020 semester. In terms of overall adaptation, teachers on average, experienced an increase in work-life balance and a decrease in turnover intentions over the course of the semester. Results also suggest that district and school leadership provide unique and complementary resources, but leader behaviours that shape initial crisis responses do not similarly affect employee responses during crisis, contrary to theory. Instead, teachers' adaptive crisis response trajectories were triggered by continued resource provision over the semester; increasing provision of valued resources (i.e., continued refinement of safety practices) and improvements in work-life balance prevented turnover intentions from spiralling throughout the crisis. Crisis management theory and research should continue to incorporate temporal dynamics and identify factors that contribute to crisis response trajectories, using designs and analyses that allow for examination as crises unfold in real time.     

Don’t worry,be happy! Positive affect at work,greater balance at home. A daily diary study on work-family balance

IntroductionThe dynamics pertaining to work-family interface such as conflict, enrichment, etc. have received considerable scholarly attention in social sciences. However, the daily processes that are involved have been examined to a lesser extent, least of all including the role played by emotions.ObjectiveThis study aimed at examining, consistently with the Affective Events Theory, if positive and negative affect experienced during the working day played a mediational role in the associations between daily levels of work-family conflict and work-family enrichment on one side, and work-family balance on the other. Moreover, the moderating cross-level role of trait emotional stability was examined.MethodThe study included a convenience sample of 104 Italian employees who completed a diary-book over five consecutive working days.ResultsMultilevel-modelling results highlighted, controlling for emotional stability, a mediational role of only daily positive affect in the relationships between both work-family conflict and enrichment on the one side and work-family balance on the other side.ConclusionThis study contributed to the literature emphasizing the role of positive affective states experienced at the workplace and their connections with the private life. Limitations and implications for research and practice are described.

Aggregating conclusive and inconclusive information: Data and a model based on the assessment of threat

This study examined the process of combining conclusive and inconclusive information using a Naval threat assessment simulation. On each of 36 trials, participants interrogated 10 pieces of information (e.g., speed, direction, bearing, etc.) about “targets” in a simulated radar space. The number of hostile, peaceful, and inconclusive cues was factorially varied across targets. Three models were developed to understand how inconclusive information is used in the judgment of threat. According to one model, inconclusive information is ignored and the judgment of threat is based only on the conclusive information. According to a second model, the amount of dominant conclusive information is normalized by all of the available information. Finally, according to a third model, inconclusive information is partitioned under the assumption that it equally represents both dominant and non‐dominant evidence. In Experiment 1, the data of novices (i.e., civilians) were best described by a model that assumes a partitioning of inconclusive evidence. This result was replicated in a second experiment involving variation of the global threat context. In a third experiment involving experts (i.e., Canadian Navy officers), the data of half of the participants were best described by the partitioning model and the data of the other half were best described by the normalizing model. In Experiments 1 and 2, the presence of inconclusive information produced a “dilution effect”, whereby hostile (peaceful) targets were judged as less hostile (peaceful) than the predictions of the Partitioning model. The dilution effect was not evident in the judgments of the Navy officers. Copyright © 2009 Crown in the right of Canada. Published by John Wiley & Sons, Ltd.     

Leaning In and Out: Work–Life Tradeoffs,Self-Conscious Emotions,and Life Role Satisfaction

Drawing on self-discrepancy theory, which posits discomfort when actual selves deviate from ideal or ought selves (Higgins, 1987), we examine the complementary and compounding effects of work–life tradeoffs on self-conscious emotions, life role satisfaction, and spouse/partner work satisfaction. Across multiple samples, we augment and refine extant tradeoff measures to include minor tradeoffs (e.g., limiting networking, missing a family event) in addition to the more frequently researched major tradeoffs (e.g., quitting a job, choosing not to have children) and test their effects. Work compromising tradeoffs (i.e., sacrificing work for family/personal activities) were associated with negative self-conscious emotions and lower levels of job, career, and life satisfaction indirectly through professional self-discrepancy, suggesting that making work compromises for family affects how individuals see themselves as professionals. Family/personal compromising tradeoffs (i.e., sacrificing family/personal activities for work) were associated with negative self-conscious emotions and lower levels of job, career, family, and life satisfaction indirectly through family and professional self-discrepancy, suggesting individuals view their family and professional selves less favorably when they make family/personal compromises for work. Despite negative effects for the employees, our results suggest work tradeoffs are beneficial for spouse/partner work hours and satisfaction.     

Therapist activities preceding therapy setbacks in a poor-outcome case

Progress in psychotherapy is typically irregular, as advances alternate with setbacks. This study investigated the therapist’s activities prior to two main types of setbacks, one involving the client following therapist proposals and one involving the client failing to follow from therapist proposals, in the case of a poor-outcome client treated with a linguistically-oriented kind of cognitive therapy. Setbacks were defined as decreases of at least one level on an index of therapeutic progress, the 8-level Assimilation of Problematic Experiences Scale (APES), in adjacent client passages. Therapist activities were coded in 361 setback episodes that each included a client pre-setback passage, a therapist passage, and a client setback passage; both client passages had been previously rated on the APES. The main categories of therapist activities showed distinctive patterns in relation to the two main types of setbacks, the therapeutic zone of proximal development and the balance strategy. The two main patterns were described as an exploratory and a challenging configuration. These patterns of therapist activities and setbacks showed how the therapist seemed to persevere with approach-guided interventions while this poor-outcome client continued to have setbacks to low APES levels.     

The relation between work-family balance and quality of life

We examined the relation between work-family balance and quality of life among professionals employed in public accounting. Three components of work-family balance were assessed: time balance (equal time devoted to work and family), involvement balance (equal involvement in work and family), and satisfaction balance (equal satisfaction with work and family). For individuals who invested substantial time in their combined work and family roles, those who spent more time on family than work experienced a higher quality of life than balanced individuals who, in turn, experienced a higher quality of life than those who spent more time on work than family. We observed similar findings for involvement and satisfaction. We identified the contributions of the study to the work-family balance literature and discussed the implications of the findings for future research.
