Efficacy of physical activity interventions on psychological outcomes in refugee,asylum seeker and migrant populations: A systematic review and meta-analysis

ObjectivesThe role of physical activity (PA) in the promotion of mental wellbeing and prevention of psychological disorders in population groups at increased risk for mental health conditions, such as migrant populations, has never been systematically investigated.MethodsWe conducted a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Pubmed, Web of Science, SportDiscus. We included randomized (RCTs), controlled clinical trials (CCT), and pre-post intervention studies, that assessed the efficacy of PA interventions in migrants, compared with any types of controls.ResultsWe included 27 studies (4166 participants) (16 RCTs; 2 CCTs; 9 pre-post design) between 1997 and 2020. Meta-analysis showed a significant beneficial effect of PA over control conditions for general functioning (SMD -0.35, 95% CI -0.83 to −0.16; 400 participants), outcome expectancies (SMD -0.78, 95% CI -1.17 to −0.40; 118 participants), self-efficacy/coping (SMD -0.28, 95% CI -0.52 to −0.03; 269 participants), and psychological symptoms (SMD -0.48, 95% CI -0.88 to −0.08; 6 RCTs; 597 participants). Similar findings were produced by pre-post intervention studies (SMD -0.35, 95% CI -0.60 to −0.10; 7 studies; 302 participants).ConclusionsMigrant populations may benefit from PA interventions to improve psychological outcomes. Uncertainty remains about the best approach to promote PA in this population, and future research should consider the complex factors that characterize the migration experience.     

权力感与亲社会倾向：自我获益的中介和情境的调节作用

本研究基于情境聚焦理论探讨权力感与亲社会倾向的关系,以及自我获益和情境所起的作用。两项研究通过测量一般权力感（研究一, N= 271）和启动权力感（研究二, N=139名）,考察权力感在不同情境（合作vs.竞争）中的亲社会倾向。结果发现：自我获益在权力感与亲社会倾向之间存在中介作用,竞争合作情境能够调节权力感与自我获益的关系从而影响亲社会倾向,在竞争下,高权者感知到更少获益,表现出更少的亲社会倾向,在合作情境下则相反。     

One country,two cultures: Implicit space–time mappings in Southern and Northern Vietnamese

What determines how people implicitly associate the “past” and “future” with “front” and “back”? According to the Temporal Focus Hypothesis (TFH), people's cultural attitudes toward time influence their implicit space–time mappings. However, previous research mainly used cross‐cultural comparison in which the cultures compared differ not only in attentional focus on temporal events, but may also differ in other cultural values. Thus, the specific role of cultural attitudes toward time has not been tested. In the current study, we compared Southern and Northern Vietnamese who have many aspects in common but demonstrate cultural differences in attitudes toward the past and future. The results showed that the two groups of participants tended to think about time according to their temporal focus. Taken together, this pattern of results showed that within‐cultural differences in temporal focus can also predict variation in space–time mappings, which provides further supporting evidence for the TFH.     

Why did Tiger Woods shoot 82? A commentary on

In a recent article, Toner and Moran (2015) argued that athletes need to pay conscious attention to body movements, and that an external focus of attention would not be effective for continued improvement at the elite level. Their arguments appear to be based on misunderstandings of the attentional focus literature. In this commentary, I clarify that adopting an external focus does not imply that performers are not aware of their body movements. Rather, an external focus (i.e., focusing attention of the intended movement effect) refers to the preparation of movement execution. I maintain that an external focus is necessary to optimize performance and learning at any level of performance.     

Effects of positive youth development programs on school, family, and community systems

A review of efforts at social system change in 526 universal competence-promotion outcome studies indicated that 64% of the interventions attempted some type of microsystemic or mesosystemic change involving schools, families, or community-based organizations in an attempt to foster developmental competencies in children and adolescents. Only 24% of the reports provided quantitative data on the change that occurred in targeted systems. However, studies containing the necessary information produced several mean effect sizes that were statistically significant, and ranged from modest to large in magnitude. These data indicate that attempts to change social systems affecting children and adolescents can be successful. Future work should measure more thoroughly the extent to which the systemic changes that are targeted through intervention are achieved, and investigate how such changes contribute to the development and sustainability of the outcomes that might be demonstrated by participants of competence-promotion programs. The authors wish to thank David Wilson for supplying the macros used to calculate study level effect sizes and Mark Lipsey for supplying the SPSS macros used to weight effect sizes and calculate mean effects across studies.

Violations of information structure: an electrophysiological study of answers to wh-questions

This study investigates brain responses to violations of information structure in wh-question-answer pairs, with particular emphasis on violations of focus assignment in it-clefts (It was the queen that silenced the banker). Two types of ERP responses in answers to wh-questions were found. First, all words in the focus-marking (cleft) position elicited a large positivity (P3b) characteristic of sentence-final constituents, as did the final words of these sentences, which suggests that focused elements may trigger integration effects like those seen at sentence end. Second, the focusing of an inappropriate referent elicited a smaller, N400-like effect. The results show that comprehenders actively use structural focus cues and discourse-level restrictions during online sentence processing. These results, based on visual stimuli, were different from the brain response to auditory focus violations indicated by pitch-accent [Hruska, C., Steinhauer, K., Alter, K., & Steube, A. (2000). ERP effects of sentence accents and violations of the information structure. In Poster presented at the 13th annual CUNY conference on human sentence processing, San Diego, CA.], but similar to brain responses to newly introduced discourse referents [Bornkessel, I., Schlesewsky, M., & Friederici, A. (2003). Contextual information modulated initial processes of syntactic integration: the role of inter- versus intrasentential predictions.

The effects of smart phone video analysis on focus of attention and performance in practice and competition

ObjectivesResearch has consistently found that focus of attention (FOA) affects motor learning and performance. However, much of the previous work has used artificially manipulated FOA of novice participants performing laboratory tasks. There is a paucity of work that has tested transfer to more complex competition environments. We aimed to investigate the effects of smart phone video analysis, which commonly occurs in natural practice settings in golf, on skilled player’s FOA and performance in both practice and competition.DesignThis study employed a mixed experimental design. The between participants factor was the use of video analysis (practice with video vs practice only) and the repeated measures factor was time point (pre-intervention vs post-intervention).MethodAltogether, 19 skilled golfers (handicap: M = 5.79, SD = 5.80) took part in a four-week practice intervention with (n = 10) or without (n = 9) the use of smart phone video analysis. Driving range performance and competition performance were measured pre- and post-intervention. Practice diaries provided measures of FOA during the intervention period.ResultsThe practice with video group displayed a significantly more internal FOA throughout the intervention period than the practice only group. This resulted in a significant time by group interaction for driving range performance that showed an increase in performance for the practice only group and a decrease for the practice with video group. However, the performance effects did not transfer to competition scores.ConclusionsFindings enhance our understanding of the effects of video analysis on FOA and question whether FOA effects transfer from on range practice to on course performance.     

The relationship between career growth and organizational commitment

This research examines the relationship between employees' career growth and organizational commitment. Career growth was conceptualized by four factors: career goal progress, professional ability development, promotion speed and remuneration growth, while organizational commitment was conceptualized using Meyer and Allen's (1997) three component model. Survey data, collected from 961 employees in 10 cities in the People's Republic of China, showed that the four dimensions of career growth were positively related to affective commitment, and that three of the facets were positively related to continuance and normative commitment. Only three of eighteen two-way interactions among the career growth factors affected organizational commitment, suggesting that the career growth factors influence commitment in an additive rather than a multiplicative manner.Results focus on how career growth can be used to manage organizational commitment.     

Exploring the acceptance of connected and automated vehicles: Focus group discussions with experts and non-experts in transport

The successful deployment of connected and automated vehicles (CAVs) will largely depend on public opinion. Expectations and concerns are essential components driving the speed of market uptake and final adoption of these technologies. We have studied user expectations and concerns, as well as their provenance, by conducting a series of Focus Group (FG) discussions with transport area experts and non-expert participants, in Italy, Germany, and Spain. Together with user acceptance, potential advantages and disadvantages that CAVs may bring at a societal level were explored. Results show that benefits like increased safety and accessibility and improved travel experience for both driver and passengers could support CAVs’ deployment. Nevertheless, a variety of concerns were raised during the discussions, related to privacy, responsibility in case of an accident, and increase in maintenance and repair costs. These aspects could significantly hamper or delay CAVs acceptability and need to be carefully considered by stakeholders. The reported insights from the FG discussions and the fact that some participants noted positive changes of their initial idea of CAVs due to their participation in the discussion, exemplify the importance of citizen engagement activities to address mobility challenges.     

When promoting a charity can hurt charitable giving: A metacognitive analysis

Charities need to come to mind to enter a potential donor's consideration set. However, feeling familiar with a charity and its cause can facilitate or impair giving. In most cases, perceived good memory for details of the cause fosters the impression of personal importance, which increases giving (Studies 1 and 3). But when the charity aims to increase awareness of a cause, good memory for the cause suggests that awareness is already high, which impairs giving (Studies 2 and 3). Hence, promotions for awareness-raising charities can actually have negative consequences, confirming the predictions of a metacognitive analysis.
