Correlations of multiple rider behaviors with self-reported attitudes,perspectives on traffic rule strictness and social desirability

Powered Two-Wheeler (PTW) riders constitute a very vulnerable group of road users, while riding a PTW is considerably more dangerous than using any other motor vehicle. Behavioral issues have been identified major moderating factors to PTW crashes, as riders display great variability in their attitudes towards road safety. Τhe aim of this paper is to present a thorough, overarching structure of relationships correlating various unsafe stated PTW rider behaviors (riding after alcohol consumption, speeding, helmet use and texting) with several self-reported attitude parameters and factors regarding rider perspectives on traffic rule strictness and social desirability. A structural equation model (SEM) was developed using data from the ESRA2 survey, which provided a broad sample encompassing 5,958 respondent riders from 32 countries. Numerous statistical relationships were discovered and quantified correlating the four examined unsafe rider behaviors with eight latent unobserved variables. All covariances between unsafe behaviors were found to be positive and statistically significant, indicating that a rider who will engage more frequently in every single one of the four examined unsafe riding behaviors is more likely to also engage in all the others as well.     

通勤恢复活动对工作激情的动态影响及其机制

员工在通勤时间里减少身心压力, 将身体和心理资源恢复到正常状态的活动称为“通勤恢复活动”。通勤恢复活动可能跨领域对人们的工作激情产生动态影响。通过日记研究法和潜在剖面分析法, 从短期和长期研究通勤恢复活动对工作激情的动态影响、内在机制和边界条件, 拟解决3个关键问题：第一, 通勤恢复活动如何影响员工的和谐型工作激情和强迫型工作激情及其内在机制是什么?第二, 不同自我调节模式的员工在通勤恢复活动影响工作激情的机制上如何发挥调节效应?第三, 通勤恢复活动各维度组合的不同剖面对工作激情有怎么样的影响?对这些问题的深入探讨, 不仅弥补通勤研究和恢复研究中被忽视却又十分重要的研究缺陷, 而且对人们开展通勤恢复活动提升通勤恢复活动以激发员工的工作激情, 同样有很强的现实意义。     

组织中个体主动性行为“利与弊”

个体主动性行为是组织中个体主动做出的面向未来和面向变革的工作行为, 近年来成为组织行为研究领域的重要议题。从现有研究来看: (1)在研究主题上, 多数研究发现了个体主动性行为可以带来正向结果, 个别学者也注意到了个体主动性行为的代价; (2)在分析视角上, 主要包括个体主动性行为对个体层面和组织情境层面的正向与负向影响; (3)在理论机制上, 个体主动性行为的“利弊”效应可用优势互补理论、自我决定理论和归因理论来解释。未来研究可着重进行以下理论整合: (1)从个体主动性行为类型出发, 基于智慧主动性的视角揭示其内在机制; (2)从主动性行为者和观察者特征两面性的视角, 实证探讨其背后机理; (3)从主动性行为主客体特征的发展视角进行动态研究。     

语素意识、快速命名对汉字听写和抄写的作用

书写是小学阶段书面语发展的重要目标之一,受到多种认知技能的影响。采用追踪研究考察了127名小学五年级儿童的语素意识和快速命名对其五、六年级时的汉字听写和抄写的影响。控制了非言语智力、语音意识后,结果发现：(1)儿童汉字听写和抄写能力随时间发展均有显著增长;(2)五年级语素意识显著预测了五、六年级两个时间点的听写,五年级快速命名仅显著预测了五年级听写;(3)五年级语素意识和快速命名预测了五年级抄写。研究表明语素意识和快速命名对汉字听写和抄写存在不同的影响作用。     

Being student leaders or ‘ordinary’ students: Children's emotional experiences of relationships with others in a Chinese school

The student leader system is commonly used in Chinese schools. Student leaders are children who are elected by classmates, then assigned by teachers, to be responsible for monitoring classmates' behaviour. Based on the data collected through an intensive ethnographic study in a rural primary boarding school in China in 2016, this article discusses emotional experiences in peer relationships reported by both student leaders and other ‘ordinary’ students, who were not student leaders. The article argues that China's student leader system is likely to create hierarchical relationships between student leaders and ‘ordinary’ students, and exposes ‘ordinary’ students to the potential risk of being exploited by student leaders. The article also argues that because of this student leader system and relevant student evaluation values, student leaders and ‘ordinary’ students all feel stressed when they are building up and maintaining peer relationships, such as friendships, with each other.     

The silent music sheet,the replica tin and the unsewn button: Materialising nostalgia in the Marks and Spencer's archive

This paper explores how nostalgia and collective memory are materialised, imagined, curated and orchestrated through the archive. Drawing upon the example of the Marks and Spencer's (M&S) archive, we argue that archives, particularly those containing objects, command nostalgia. They re-appropriate objects, memories and their histories into contemporary narratives. This paper adds to a body of work within and beyond geography and sociology exploring the potency and creativity of everyday materials and their ability to produce, imagine and memorialise affinities between people, places and past times. This raises questions about the politics of memory, the authenticity of objects and the nostalgic imaginaries they enliven, what we discuss as ‘faux nostalgia’. We illustrate how M&S is part of collective British memory, promoting middle-class ideals of British family life. The archive and objects on display materialise such imaginaries, creating a yearning for the spirit, values and opportunities of times gone by; interweaving them into contemporary narratives of family life to create unattainable ideals. We reflect upon the biographies of three objects from the archive: a music sheet, an unsewn button and a replica tin. By making these objects central to our account, we illustrate how they materialise and recollect nostalgia through the archive.     

Critical geographies of love and loss: Relational responses to the death of a spouse in Senegal

Marriage practices in the Majority world may differ considerably from dominant cultural ideals in the Minority world of ‘romantic love’ and ‘companionate marriage’ based on monogamous relationships. Similarly, mourning in the ‘Rest’ of the world often diverges from assumptions within Anglophone bereavement studies of a ‘grieving journey’. This paper provides a gendered, spatial, relational analysis of responses to the death of a spouse in Senegal, based on in-depth interviews with Serer women and men in rural and urban communities. A heightened sense of relationality with the deceased surrounded widows' bodies, with permeable boundaries that needed to be contained and “purified” through widowhood-mourning practices in order to restore social cohesion. For men, the space of the home was transformed, sometimes unbearably, by the loss of a wife and mother due to their central role in home-making practices, transforming men's relational being. ‘Embodied relationality’, alongside material constraints, also shaped perspectives on remarriage. The paper reveals the diverse material, embodied, spatial, and often explicitly gendered, ways that the effects of the death of a spouse may be manifested in the experience of the living person and draws attention to the permeable embodied boundaries of ‘relational being’ that encompass the living and the dead.

Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.     

A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.
