Time spent on the Internet by multicultural adolescents in Korea

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them.     

Making Space for Place: Mapping Tools and Practices to Teach for Spatial Justice

This article presents a set of spatial tools for classroom learning about spatial justice. As part of a larger team, we designed a curriculum that engaged 10 learners with 3 spatial tools: (a) an oversized floor map, (b) interactive geographic information systems (GIS) maps, and (c) participatory mapping. We analyze how these tools supported learning using notions of politicization. The floor map fed conceptual understandings of the map as a representational text and served as the terrain for an embodied activity to support proportional reasoning about inequitable distributions of resources. The data-rich GIS maps and their zoomability allowed for coordinating across multiple variables to connect patterns in inequities to other social processes. The participatory mapping enabled learners to make discoveries about, connect, and share beyond the individual classroom counterstories from people in the lived streets of their neighborhood. In aggregate, this set of spatial tools produced a complex, hybrid view of the city’s space, which contributed to learners’ political formation.

轴向柱塞泵流体噪声的机理分析

以降低轴向柱塞泵流体噪声为目的，围绕轴向柱塞泵的柱塞数和轴向柱塞泵配油盘结构对产生流体噪声的机理进行了理论分析，并对降低轴向柱塞泵流体噪声的措施进行了试验。试验研究表明：对轴向柱塞泵配油盘结构进行优化设计，使柱塞腔内高压油与低压油切换时避免高、低压油突然串通而造成的压力冲击所产生的噪声，是降低轴向柱塞泵流体噪声的一条有效途径。     

我国科技期刊文献引文的聚散性分析

以《中文核心期刊要目总览》2000版为依据，对其中的科技期刊文献的引文进行统计分析。结果表明，科技文献引文具有明显的聚散性，聚散程度的高低与学科性质有关。采用引文分析方法揭示科技期刊文献的分布规律并确定核心期刊，最关键的是要选好一定时域内最具有代表性的一组期刊作为引文统计源，其次是对于不同的学科，划定核心区，应采用不同的引文量比例。

LINC: biology's revolutionary little computer

The 1963 LINC (Laboratory INstrument Computer) stands at the center of two stories: the computerization of the biologist's laboratory and the advent of small-scale computing. The brainchild of Wesley Clark, 'the most brilliant computer designer of his generation', LINC was developed specifically to address the failure of biologists to adopt computer technology. To meet their unique needs, Clark built a machine the radical design of which defied and subverted the then dominant conventions of computer architecture.     

工科院校大学生网络成瘾与人格特征的关系

目的了解工科院校大学生网络成瘾现状及其与人格特征的关系,为多方面理解网络成瘾及其矫治提供依据。方法采取随机抽样的方法从西安市某工科院校抽取学生共262人,用网络成瘾量表和艾森克人格量表对研究对象进行测试。结果网络成瘾检出率为41.8%;男生网络成瘾程度显著高于女生;大三、大四学生网络成瘾程度显著高于大一学生,大三学生成瘾程度显著高于大二学生和大四学生;大学生的网络成瘾程度与神经质、精神质呈显著的正相关,与掩饰性呈显著的负相关,与内外向的相关不显著。结论人格特征在一定程度上可以预测网络成瘾的程度。     

Transformative Professional Learning Within Schools: Relationship to Teachers’ Beliefs, Expertise and Teaching

Although scholarship and research have demonstrated the positive impact of professional learning on academic teaching and learning, an inadequate amount of research has examined how professional learning is associated with transformative teaching for equity, diversity and social justice. This survey study explored the relationship between professional learning and teachers’ beliefs about diversity, transformative expertise, and transformative teaching by comparing two models of professional learning in 25 small urban elementary schools. Results indicated that factors in both the process and transformative content models predicted differences in teachers’ reported beliefs, expertise, or teaching. While some factors such as learning to teach for social justice consistently predicted increased transformative practices, other factors failed to predict or were associated with decreased transformative practices. After discussing the findings, implications for practice, theory and research are offered.
