Thrilling travel or lonesome long haul? Loneliness and acculturation behavior of adolescents studying abroad     

《Int J Intercult Relat》2021

Studying abroad far away from family and friends may put young people at particular risk of experiencing loneliness. From this perspective, behavioral strategies to deal with the challenges of a new living environment have important implications for the development of loneliness over the course of an educational stay abroad. This study investigates adolescents’ experience of loneliness over the course of a school year abroad, as well as the longitudinal interplay between loneliness and the sojourners’ host- and home-cultural behavioral engagement. To that end, we analyzed data from 1,225 student sojourners using latent growth curve models and cross-lagged panel models. Participants were surveyed four times before and during the student exchange period using online questionnaires. Our results showed that loneliness increased during the transition from home to the host country but decreased again afterwards. Host-cultural behavioral engagement predicted lower levels of loneliness by a direct effect, whereas home-cultural behavioral engagement predicted higher levels of loneliness by a time-lagged indirect effect via host-cultural behavioral engagement. Implications for acculturation and loneliness research, and practical implications for the support of student sojourners are discussed.  相似文献   

How teachers’ individual autonomy may hinder students’ academic progress and attainment: Professionalism in practice     

Christopher Day 《British Educational Research Journal》2020,46(1):247-264

This article reports a 3-year case study of a primary school in England, in which a recently appointed principal attempted to build ‘collegial professional autonomy’ (Nordic Journal of Studies in Educational Policy, 2 , 2015, 20) within a push to improve students’ progress and attainment. The research examined the tensions between staff who embraced the principal's agenda for collegially agreed change, and whose students’ academic progress and performance improved over a 3-year consecutive period when measured in terms of students’ entry-level attainment and socio-economic factors, and staff who asserted their right to ‘individual professional autonomy’ and whose students’ academic progress and attainment declined. The research: (i) challenges claims that reform necessarily results in school cultures of compliancy, de-professionalisation and the technicisation of teaching; (ii) raises issues concerning the pedagogical leadership of principals in a devolved, ‘self-governing’ school system; and (iii) questions teachers’ entitlements to individual professional autonomy where this is associated with students’ continuing academic underperformance.  相似文献   

Understanding value in the student experience through student–staff partnerships     

Mollie Dollinger  Jason Lodge 《高等教育研究与发展》2020,39(5):940-952

ABSTRACT

Questions such as ‘what is value in the student experience?’ and ‘how do we measure or assess value in higher education?’ remain an under-researched area. However, in the context of marketisation and competitive forces in higher education, there is a need to unpack what is value in the student experience. In this article, a conceptualisation of value that can be applied in higher education (known as value-in-use) is introduced and applied to a specific and increasingly important aspect of the student experience – student–staff partnerships. Qualitative survey data (n?=?97) and interviews (n?=?35) from ten cases of various manifestations of student–staff partnerships in the Australasian context is presented and assessed in relation to value. The findings highlight that student–staff partnerships may enhance value in the student experience and that value-in-use may be an appropriate lens through which to continue to explore how value is created and measured in the student experience.  相似文献

Subspace design of low-rank estimators for higher-order statistics     

Ivan Bradaric  Athina P. Petropulu  Konstantinos I. Diamantaras 《Journal of The Franklin Institute》2002,339(2):161-187

Higher-order statistics (HOS) are well known for their robustness to additive Gaussian noise and ability to preserve phase. HOS estimates, on the other hand, have been criticized for high complexity and the need for long data in order to maintain small variance. Since rank reduction offers a general principle for reduction of estimator variance and complexity, we consider the problem of designing low-rank estimators for HOS. We propose three methods for choosing the transformation matrix that reduces the mean-square error (MSE) associated with the low-rank HOS estimates. We also demonstrate the advantages of using low-rank third-order moment estimates for blind system estimation. Results indicate that the full rank MSE corresponding to some data length N can be attained by a low-rank estimator corresponding to a length significantly smaller than N.  相似文献   

伦理型领导、组织认同与员工亲组织非伦理行为:特质调节焦点的调节作用     

李根强 《科学学与科学技术管理》2016,(12):125-135

亲组织非伦理行为(unethical pro-organizational behavior,UPB)对企业声誉和社会利益造成严重危害,设法防止UPB的发生显得尤为迫切。基于组织认同理论和调节焦点理论,通过对489名企业员工进行问卷调查,研究伦理型领导对员工亲组织非伦理行为的影响机制,包括这一机制中组织认同的中介作用和特质调节焦点的调节作用,以制定相应的防范策略。结果发现:伦理型领导与UPB呈倒U型关系;组织认同在伦理型领导和UPB的关系间起中介作用;特质调节焦点调节了伦理型领导与UPB之间的倒U型关系。  相似文献
