Explaining the substantial inter-domain and over-time correlations in student achievement: the importance of stable student attributes

Multi-domain and longitudinal studies of student achievement routinely find moderate to strong correlations across achievement domains and even stronger within-domain correlations over time. The purpose of this study is to examine the sources of these patterns analysing student achievement in 5 domains across Years 3, 5 and 7. The analysis is of longitudinal population data of over 22,000 students and utilizes fixed-effects models to incorporate stable general and domain-specific latent factors. These latent factors correspond to a general cognitive-ability-like factor and specific aptitudes in particular, or types of, subject areas. The preferred model incorporates both general and domain-specific latent factors with stronger effects for the general factor, although the domain-specific factors are particularly strong for spelling and numeracy. When taking into account general and domain-specific latent factors, the effects of student’s socioeconomic status (SES) and school SES are trivial.

等离子喷涂复合涂层结构对力学性能影响的有限元分析：网状孔隙结构的影响

本研究的目的是进一步理解等离子喷涂制备的复合涂层在外力作用下内部应力场的规律。目前,相关方面的报道较少。为了达到这个目的,采用扫描电镜获得高分辨率的涂层照片,经过离散化处理,并进行有限元分析。Al2O3-13TiO2等离子喷涂涂层是一个比较理想的研究目标。通过调整喷涂参数获得了不同的多孔结构,例如孔隙率、裂纹密度、裂纹方向等。数值模拟显示网状孔隙结构对涂层内应力场有显著的影响。同样的,通过改变相的本征力学属性,研究了其它成分的涂层。在理想状态下,仿真结果显示第二相对涂层内部应力场的影响较弱。另外,提出了一种通用的涂层性能分析方法,指出了它的优点和局限性,并强调其重要性（REV）。

浅议新生代农民工的主观幸福感

新生代农民工这一庞大群体已成为我国当今农民工的重要组成部分和劳动人民的主体,已经引起整个社会的高度关注。新生代农民工主观幸福感的状况是农民工生活质量的反映,对其身心健康发展有积极的作用。富士康“连环跳楼”事件表明我国新生代农民工的心理健康问题令人担忧。分析了新生代农民工当前生活的现状,以及新生代农民工低幸福感的原因如不良心态、公共制度、知识结构,并针对性地提出有效提高新生代农民工主观幸福感的途径,这对优化新生代农民工生活质量,提高身心健康水平,有一定的实践意义。     

Designing for communication at work: A case for technology-enhanced boundary objects

In this article we conceptualise the challenges of communication between a mortgage company and its customers in terms of crossing boundaries between communities. Through an ethnographic study we first address the question: what are the challenges of communication between sales agents and customers of a mortgage company around mathematical artefacts? Insight into these challenges formed the basis for an intervention in which we designed technology-enhanced boundary objects (TEBOs) that were reconfigurations of problematic symbolic artefacts. Secondly, we ask what the sales agents learned from the intervention. The data suggest that the intervention with the TEBOs helped employees to develop a better understanding of the mathematics behind the mortgages they sold, and to improve communication with their customers.

A ‘whole-school/community development’ approach to preventing and countering bullying: the Erris Anti-Bullying Initiative (2009–2011)

This paper describes how a ‘whole-school/community development’ anti-bullying programme was designed, implemented and evaluated in an initiative in Erris, Co. Mayo, Ireland, involving local primary and post-primary schools and community groups. Students from seven participating schools (five primary, two post-primary) completed modified versions of the Olweus Bully/Victim Questionnaire both prior to and following programme implementation. Thereafter, there were reductions in students' reports of involvement in bully/victim problems and increases in their reports of feelings about bullying and countering bullying that were consistent with an anti-bullying ethos. The sizes of these effects were modest, in some cases perhaps due to the significantly low incidence of students' involvement in bully/victim problems prior to the programme. This model is in continued use in Erris, and in its further development it is intended to seek out opportunities to implement and evaluate it in other locations.
