Testing the validity of social capital measures in the study of information and communication technologies

Social capital has been considered a cause and consequence of various uses of new information and communication technologies (ICTs). However, there is a growing divergence between how social capital is commonly measured in the study of ICTs and how it is measured in other fields. This departure raises questions about the validity of some of the most widely cited studies of social capital and ICTs. We compare the Internet Social Capital Scales (ISCS) developed by Williams [2006. On and off the ’net: scales for social capital in an online era. Journal of Computer-Mediated Communication, 11(2), 593–628. doi: 10.1111/j.1083-6101.2006.00029.x] – a series of psychometric scales commonly used to measure ‘social capital’ – to established, structural measures of social capital: name, position, and resource generators. Based on a survey of 880 undergraduate students (the population to which the ISCS has been most frequently administered), we find that, unlike structural measures, the ISCS does not distinguish between the distinct constructs of bonding and bridging social capital. The ISCS does not have convergent validity with structural measures of bonding or bridging social capital; it does not measure the same concept as structural measures. The ISCS conflates social capital with the related constructs of social support and attachment. The ISCS does not measure perceived or actual social capital. These findings raise concerns about the interpretations of existing studies of ‘social capital’ and ICTs that are based on the ISCS. Given the absence of measurement validity, we urge those studying social capital to abandon the ISCS in favor of alternative approaches.

Brexit: Be Careful What You Wish For?

In this paper, I focus on the British future from Brexit. The institutional form this will take is not yet fixed. However, one can consider likely outcomes based on dominant economic frameworks. From this perspective, it seems unlikely that Brexit will address the actual grievances that resulted in Brexit. These transcend European Union membership.     

C14. Moments of the kolmogorov-smirnov one-sample statistic

In adaptive estimation, it is often considered that an estimator has made a mistake if the component estimator chosen for use is not the most efficient for the distribution sampled. Theoretical and simulation results point to a fallacy in this line of thought. The Monte Carlo study involves extension of the Princeton Swindle to distributions conditional on a location and scale-free statistic, and to the uniform. The results give a partial explanation for the sometimes surprising robustness of adaptive L-estimators.     

网络环境下的图书馆文献典藏——从民初笔记野史《乌蒙秘闻》说起

由于网络数字技术的冲击,大量久藏深闺的文献资料流布天下,偶有引起认识或研究的混乱。《乌蒙秘闻》一书是许指严在民初"反满"思想的影响下,为生计考虑,以清初滇东北改土归流为背景创作的一篇传奇小说,本不足信。但网络上却较常见,有称"中外名著"的,有称"重要资料"的,还出现了专门的词条,这就对当前承担公共服务的图书馆等部门提出了新的要求和任务。

高校思想政治教育网络教育手段的理性分析

网络技术运用于高校思想政治教育,不仅丰富了思想政治教育的途径和方式,而且也有效地拓展了思想政治教育的空间。但是由于思想观念、技术水平的差异性,网络为思想政治教育提供的手段并没有得到充分地开发利用。因此,大胆实施改革创新,不断完善网络教育手段和方式,是促使思想政治教育功能得以最大程度发挥的重要基础。     

Open spaces for dialogue promoting mental health as a social work education methodology

ABSTRACT

The authors discuss service user involvement as a key approach regarding training of social workers. In many European Union countries this is a stable practice with a lengthy tradition in research and application. However, in Poland it is almost entirely absent and marginalized. This article presents the results of a participatory action research project conducted at the Institute of Sociology of the Jagiellonian University in Krakow, the objective of which was to identify and critically analyze the key substantive and formal aspects of training of social workers with the participation of individuals with experience of mental illness. This research project adopted an open approach to cognizing reality based on qualitative co-participatory methods. In the conclusion, the authors emphasize that the fundamental criterion for the success of this particular form of training is voluntary and differentiated participation of students—both in the role of people sharing their own experience and as learners—as well as shaping a culture of open dialogue, educational alliances of recognition and recovery, the foundation of which is axiological experience.     

高铁网络下的中国十大城市群旅游交通格局及其经济联系的比较研究

旅游交通是旅游经济发展中重要的内容之一,通过对中国十大城市群城市旅游交通可达性、铁路交通流分布情况与旅游经济联系、总量和隶属度进行计算,借助Arcgis10.2对中国十大城市群交通空间流分布情况和旅游经济联系进行空间可视化处理,并对计算结果进行综合比较分析。研究发现:高铁使得中国十大城市群城市旅游交通可达性水平得到大幅提升,且交通流分布均衡。中国十大城市群城市可达性的提升给城市旅游经济带来了一定的积极影响。高铁网络下中国十大城市群旅游经济联系分布不均衡。
