Each year, Canada attracts thousands of skilled workers from ‘South Asia’; yet, relatively little is known about the complex reasons for and processes of migration of this immigrant cohort. The situation becomes even more acute when research ignores the internal diversities within this complex group and portrays a homogenised picture. Focussing on the experiences of 80 South Asian households who have entered Canada as skilled workers, this paper concludes that migration experiences differ between and within national groups (Indian, Bangladeshi and Sri Lankan). Various factors, including pre-migration political, economic and social contexts, transnational ties and social identities and hierarchies play an important role in motivating this highly mobile group and creating specific migration channels. In order to develop a wholistic and nuanced understanding of migration, the study advocates that, conceptually, it is imperative to move away from meta-narratives and models of migration, and methodologically, it is necessary to continue using mixed research methods. 相似文献

The purpose of this study was to evaluate the relationship between body mass index and motor competence in Santal children 5–12 years old. A total of 816 Santal children were studied. Children's adiposity status was assessed by body mass index (BMI) for age z-score based on World Health Organization reference data. Motor competence was measured using the Bruininks-Oseretsky Test of Motor Competence (BOT-2). There was no significant difference in mean BMI z-score between Santal boys (0.13 ± 0.07) and girls (?0.14 ± 0.07). Healthy weight (HW) children scored higher (p < .05) in some individual motor subtests (bilateral competence, balance, running speed and agility, upper limb competence, and strength) and in total BOT-2 score (p < .05) compared with scores for underweight (UW) and overweight (OW) children. Nonlinear regression analysis showed that BMI is a significant independent predictor of motor competence (p < .01). Motor competence showed a curvilinear relationship with BMI-z-score, with the lowest point motor scores in strength and upper limb competence (p < .05) for both UW and OW children compared to HW children who scored highest. The results also indicated that gross motor skills, but not fine motor skills, were poorer among children who were UW or OW compared with HW children. 相似文献

Firms may choose to present the price of a multicomponent product bundle in partitioned (separate price for each mandatory component) or consolidated (single, equivalent price) fashion. In this article, we report on 2 experiments that examined the effects of such presentations on evaluations and choices as well as the underlying processing effects. In Experiment 1, consistent with a mental accounting analysis, a multicomponent product bundle was evaluated more favorably and chosen more often when its components were presented with partitioned (vs. consolidated) prices. The effects were, however, moderated by the component partitioned. In particular, it appeared that partitioning prices altered attention paid to the components partitioned and related product features. In Experiment 2, we found that different splits of the bundle price influenced evaluations and choices depending on how the focal product price related to that of a comparison option. These price‐split effects were also moderated by the component partitioned, suggesting attention effects similar to Experiment 1. The findings show that although the effects of price partitioning were consistent with mental accounting principles, they were moderated by information processing effects related to the partitioned component. 相似文献

A prenatal intervention designed to prevent the onset of major depressive episodes (MDEs) during pregnancy and postpartum was pilot tested at a public sector women’s clinic. The Mamás y Bebés/Mothers and Babies Course is an intervention developed in Spanish and English that uses a cognitive-behavioral mood management framework, and incorporates social learning concepts, attachment theory, and socio-cultural issues. The four goals of this project were to develop the intervention, assess its acceptability, test the feasibility of conducting a randomized trial with public sector patients, and obtain estimates of its effect size. Forty-one pregnant women at high risk for developing MDEs were randomized to the Mothers and Babies Course (n = 21) or a comparison condition (n = 20). Assessments occurred during pregnancy and at 1, 3, 6, and 12 months postpartum. Differences in terms of depression symptom levels or incidence of MDEs between the two groups did not reach statistical significance in this pilot trial. However, the MDE incidence rates of 14% for the intervention condition versus 25% for the comparison condition represent a small effect size (h = 0.28) that will be further examined in a larger scale study. The intervention was well received by the participants and implementation of a randomized trial appeared quite feasible as indicated by our follow-up rate of 91% at 12 months. Implications for the continuing development of preventive interventions for perinatal depression are discussed. 相似文献

ABSTRACTThis study tests the hypothesis that situational judgment tests (SJTs) with interpersonal content reflect implicit beliefs about the utility of prosocial action for job effectiveness and that agreeable people are more likely to believe that prosocial action is effective. Two hundred ninety-four undergraduates completed four different SJTs with interpersonal content and a measure of Agreeableness. Results show that the effectiveness of response options in these SJTs is positively correlated with the level of prosociality they express and that because of their prosocial elements, scores on different SJTs are correlated with one another and with Agreeableness. These results shed light on the construct-related validity of SJTs with interpersonal content and point to the possibility that they can assess prosociality in job settings different from those described in their items. 相似文献

ABSTRACTThe variant selection criteria during β to α phase transformations in a metastable β-titanium alloy (Ti-5553) in the presence of deformation are examined. Two distinct metallurgical states in the β matrix, heavily deformed and fully recrystallized, were obtained from a 90% cold-rolled alloy. The deformed and recrystallized samples were subjected to aging heat treatment for a short time to allow the precipitation of an intragranular α phase. Electron backscattered diffraction was used to assess the α crystallographic variant occurrence in the deformed as well as in the recrystallized β grains. A discrete pole figure analysis revealed that a limited number of variants were evolved in the deformed β grains while there was no variant selection in the recrystallized β matrix. The results suggest that activation of {112}<111>β slip systems determines a strong variant selection in the plastically deformed β matrix. 相似文献

Transfer to intermediate forms following concept discrimination by pigeons: chimeras and morphs 下载免费PDF全文
Two experiments examined pigeons' generalization to intermediate forms following training of concept discriminations. In Experiment 1, the training stimuli were sets of images of dogs and cats, and the transfer stimuli were head/body chimeras, which humans tend to categorize more readily in terms of the head part rather than the body part. In Experiment 2, the training stimuli were sets of images of heads of dogs and cats, and the intermediate stimuli were computer-generated morphs. In both experiments, pigeons learned the concept discrimination quickly and generalized with some decrement to novel instances of the categories. In both experiments, transfer tests were carried out with intermediate forms generated from both familiar and novel exemplars of the training sets. In Experiment 1, the pigeons' transfer performance, unlike that of human infants exposed to similar stimuli, was best predicted by the body part of the stimulus when the chimeras were formed from familiar exemplars. Spatial frequency analysis of the stimuli showed that the body parts were richer in high spatial frequencies than the head parts, so these data are consistent with the hypothesis that categorization is more dependent on local stimulus features in pigeons than in humans. There was no corresponding trend when the chimeras were formed from novel exemplars. In Experiment 2, when morphs of training stimuli were used, response rates declined smoothly as the proportion of the morph contributed by the positive stimulus fell, although results with morphs of novel stimuli were again less orderly. 相似文献

Attachment styles may influence interpersonal strategies used to cope with stress. We examined links between attachment style, communicative behaviors, and physical well‐being among 166 couples coping with cancer. Results of actor–partner interdependence mediation models indicated that insecure attachment styles were associated with greater self‐report of two different and seemingly contradictory communicative behaviors (disclosure and holding back), which in turn were associated with poorer physical well‐being. These effects were intrapersonal for both patients and spouses, with the exception of anxious attachment and holding back for spouses. They were also interpersonal in that spouse insecure attachment was associated with poorer patient physical well‐being through spouse communication (greater holding back and disclosure). Couple‐based communication interventions to support adjustment should consider attachment style. 相似文献

Is What You Feel What They See? Prominent and Subtle Identity Signaling in Intergroup Interactions 下载免费PDF全文
Individuals often signal group affiliations to others, and the display of such identity signals is frequently rather subtle. While prior work has focused on understanding an individual's choices of subtle versus prominent signals, in this work, we look at the downstream consequences of such choices. Specifically, we explore how the prominence of identity signals may affect one's behavior in intergroup interactions. Drawing from literature on processing fluency, we propose that the use of difficult to process (subtle) identity signals in intergroup interactions leads signalers to experience identity threat, lowering confidence in their identity and leading them to engage in behaviors to recover from this experience. Across three different identity domains (college affiliation, political affiliation, and brand loyalty), we show that when individuals use difficult to process identity signals, they derogate out‐group members in communication and behave less cooperatively in intergroup interactions. We find that these effects depend upon the observability of the signals by out‐group members and only occur for individuals who are highly identified with the in‐group. We also find that the effects are attenuated when behavior towards members of the out‐group is made public. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献
