(When) Is job-finding via personal contacts a meaningful concept for social network analysis? A comment to

Chua (2011) argues that in a meritocratic context, institutions restrict the usefulness of social networks in exerting influence on job seekers’ earnings. Regressing job-finding via personal contacts on earnings, he finds negative effects of influence via personal contacts, especially for the well-educated and individuals working in the state sector. In this comment, I argue that these results are ambiguous because (1) the analysis does not sufficiently distinguish between job ‘search’ methods and job ‘finding’ methods, (2) job-finding method indicates information flow rather than a personal contact's influence, and (3) it remains unclear whether Chua's analysis reflects the effect of network usage in job search per se or the effect of self-selection into network usage by individuals with low earning potential.     

RESEARCHING RELATIONSHIPS FROM AN ATTACHMENT PERSPECTIVE: THE USE OF BEHAVIOURAL,INTERVIEW, SELF‐REPORT AND PROJECTIVE MEASURES

Having demonstrated its credentials as one of the more elegant and robust conceptualisations of human relationships, attachment theory has considerable relevance to social work. Attachment‐based research has flourished over the past few years and it now includes an impressive array of studies across the lifespan. This article considers four different measures used in attachment‐based research, although more discussion is devoted to interview and projective measures because they specifically embrace a psychodynamic approach in their design and analytic focus. The aim of the article is to provide a brief overview of each measure and to offer some illustrative examples using practice‐related material.     

分层教学中分层基础的确立——基于皮亚杰的认知发展阶段理论

分层教学是指将学生按照一定的分层基础分成不同的层次进行差别化教学的教学形式,通过分层教学可以更好的满足学生的个性化发展,让每个学生以自己最佳的学习状态完成学校要求的学习内容,但是以往的分层教学中的分层基础有很多的弊端,无论是班内分层还是混班分层虽然解决了部分问题,但是却带来了很多其他由于分层基础带来的学习问题。所以,通过借鉴皮亚杰的认知发展阶段理论,将其作为分层教学的分层基础依据,能够更好地适应学生身心发展条件,科学合理的将分层教学有效地运用与发展。     

情境支撑活动与“第二人生”中的学习迁移

情境迁移理论强调学习情境性对成功迁移具有不可或缺的重要意义。支撑-活动观是情境理论的代表性迁移观点,强调成功的迁移离不开能够提供有效支撑的真实情境。Second Life是建立在Web2.0平台上的三维虚拟社区,该社区为实训学习提供了良好的情境。以支撑-活动情境理论为指导,探讨Second Life(SL)如何促进实训学习的迁移。     

Asymptotic Theory of Outlier Detection Algorithms for Linear Time Series Regression Models

Outlier detection algorithms are intimately connected with robust statistics that down‐weight some observations to zero. We define a number of outlier detection algorithms related to the Huber‐skip and least trimmed squares estimators, including the one‐step Huber‐skip estimator and the forward search. Next, we review a recently developed asymptotic theory of these. Finally, we analyse the gauge, the fraction of wrongly detected outliers, for a number of outlier detection algorithms and establish an asymptotic normal and a Poisson theory for the gauge.     

The ‘affective security curriculum’: breeding JBs through the marriage of the academic and the jingoistic

How does the US recruit its citizen spies used to maintain and proliferate coercive power? I use an interdisciplinary approach and a framework of affect theory to argue that there is an ‘affective security curriculum’ (ASC) that assists in explaining the tendencies towards jingoism used in the recruitment and indoctrination of students – as future security workers – in certain academic disciplines. The ASC is precisely the phenomenon that works to construct this expert class and is produced by order words, the most crucial of which is ‘terrorism’, as well as larger cultural norms linked to neoliberalism that have achieved near total dominance since the 1980s. The ASC works by intensifying the (in)ability to act for those in its domain. The necessity of linguistically proficient security workers to the US’ hegemonic project makes this a question of considerable political importance. The ASC is a different approach to answering questions of how US hegemony is maintained. Whereas positivist research agendas, such as content analysis, and postpositivist approaches, such as critical discourse analysis, certainly have their uses (and to which my notion of ASC is indebted), paradigms such as these fail to focus on the engendering processes at work vis-à-vis the expert class, without which the discursive frames such methodologies analyse would simply dissipate. My overarching purpose in this paper is to develop the concept of the ASC, its quiddity, and to present at least an incipient methodology for analysing its critical duties. As my primary intent is to introduce and conceptualize the theoretical framework of the affective security curriculum, the applied segment of this endeavour will be relatively brief – and is designed as a primer for further research.

When work keeps us apart: a thematic analysis of the experience of business travellers

Whilst business travel is deemed important for organisational success and economic outcomes, little is known about the actual process of business travelling from the perspective of individuals who undertake such travel on a regular basis. Thus the current qualitative study examined how business travellers (three women and eight men) attempt to find a balance between work and family, by focusing on how time together and time apart are experienced. The results can be interpreted and framed within work/family border theory in that business travellers' borders are less defined and less permeable, thus requiring them to border-cross more frequently. This necessitates a process of negotiation with key border-keepers (their spouse/partner). Business travellers also undertake compensatory behaviours to make up their time away from family. In order to find a work/family balance, they go through a process of adapting, negotiating and tailoring their lives around their work commitments to alleviate work–life conflict.     

投资组合动态VaR预测模型和预测精度评价
