Personal reactions to ‘strange’ situations: Attachment styles and acculturation attitudes of immigrants and majority members     

Jan Pieter Van Oudenhoven  Jacomijn Hofstra 《Int J Intercult Relat》2006,30(6):783

A growing number of studies examine the influence of individual factors on acculturation attitudes of immigrants, but few studies focus on majority members’ attitudes. In this paper, two studies are reported on the relation between attachment styles and acculturation attitudes of both immigrants (N=177) and majority members (N=243) in the Netherlands. Until now very few studies have associated cultural adjustment with attachment styles. This is remarkable, because attachment theory refers to interaction with others in new situations. Four different styles of attachment (the secure, dismissing, preoccupied and fearful attachment styles) are related to Berry's classification of acculturation attitudes. People, both immigrants and majority members, with a secure attachment style were positive towards integration, whereas people with a dismissing attachment style were not. Dismissing immigrants were more positive towards separation. Whereas both immigrants and majority members with a secure attachment style showed a similar pattern of correlations between attachment and acculturation, they seem to react quite differently, and even in opposite ways, when they have a preoccupied attachment style. Yet, the different reactions may be caused by the same psychological process: The existential ambivalence of preoccupied people may lead to diverse reactions.  相似文献

朱健民  李群 《山东体育学院学报》2002,18(1):46-48

采用问卷调查法，对中学初一至高三的568名男女学生进行应激状态、生活充实度及行为意向的调查分析？结果表明，中学生应激水平随年龄增长而生活充实度则显下降，高应激低充实的年龄特征十分明显。中学生应对高应激低充实的行为意向以睡眠娱乐为主，身体锻炼手段未被广泛认可。  相似文献   

Being in the archive: affect and scholarly distance     

Bernadette Brennan 《档案与原稿》2018,46(1):3-17

Working in the archives of living writers provides exciting possibilities for extended interpersonal research as well as ethical challenges. This article explores the author’s experience of working in Helen Garner’s restricted archives and negotiating the demands of scholarly objectivity with an increasingly felt empathic engagement. The author traces a chronological path through the archives relating to Garner’s three substantial works of non-fiction: The First Stone (1995), Joe Cinque’s Consolation (2004) and This House of Grief (2014). She draws attention to some of the ways in which distance and objectivity can be influenced not only by contact with a living writer but also by the space in which the archive is encountered. With a deliberate focus on the lived experience of researching, rather than a scholarly examination of archival theory, the author offers a case study of how the interaction of archives and living subject can shape research and publication.  相似文献

A prospective examination of the impact of high levels of exercise training on sedentary behaviour     

Ann M. Swartz  Nora E. Miller  Young IK Cho  Whitney A. Welch  Scott J. Strath 《European Journal of Sport Science》2017,17(2):222-230

The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (?3, ?2, and ?1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Results: Twenty-three individuals (mean?±?S_x: 34.4?±?2.1y, 23.0?±?1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2?±?9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute^?1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.  相似文献   

Exploring Verbal,Visual and Schematic Learners' Static and Dynamic Mental Images of Scientific Species and Processes in Relation to Their Spatial Ability     

Sulaiman M. Al-Balushi 《International Journal of Science Education》2013,35(3):460-489

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.  相似文献
