有限宽裂纹板受一对集中剪力时弹塑性解

针对运用断裂力学传统方法进行裂纹尖端的弹塑性应力场分析均为小范围塑性区的假定，不能准确反映塑性区应力情况的问题，利用裂纹线场分析方法，对理想弹塑性材料的有限宽平面板在裂纹面受到一对集中剪力作用时裂纹线附近的应力场及弹塑性边界进行了分析。不采用小范围塑性区的假设，直接通过将裂纹线附近弹塑性边界上弹性应力场与塑性应力场的匹配，获得了裂纹线附近弹塑性应力场的解析解以及弹塑性边界上单位法向量的表达式。用裂纹线分析方法可以准确地反映裂纹附近的弹塑性应力分布，该种方法的应用将成为断裂力学的一个重要发展方向，对石油天然气构造应力分析、材料力学分析具有参考价值。     

From a Bird's Eye View? A Comparative Analysis of Governance and Network Integration Among Human Service Organizations

ABSTRACT

It is widely recognized by social workers and human service administrators that interorganizational networks are an important aspect of the everyday reality of human service organizations. A well-integrated network is defined as a network in which all organizations are connected and the resource exchange among all network actors is guaranteed. To analyze the integration of service networks, this study conducts a social network analysis of four networks among service organizations governed by a shared-participant type of governance. The results indicate that in networks in which the governance is more developed and mature, the structure shows a high level of integration. The analysis and results show that governance leads to an integration of the efforts of diverse service organizations, ultimately increasing the responsiveness of the entire network toward the complex problems of the target group. Future recommendations include discussing further qualitative and quantitative research efforts and the role of shared-participant governance.     

Differential fertility in Ontario. An application of factorial design to a demographic problem

This paper describes the use of a probability sample to survey differential fertility. 475 women were randomly selected from the 1941 Census of Canada to provide tests of the existence of five differentials: income, present age, age by marriage, schooling and distance from a city. The sample was limited to one province and to two contrasting values of each of the five differentials under study. Significant differences are found for the effective distance as well as for age at marriage and schooling. This is taken as signifying that the diffusion of the small-family pattern has a spatial dimension.

Intersubjectivity: Towards a Dialogical Analysis

Intersubjectivity refers to the variety of possible relations between perspectives. It is indispensable for understanding human social behaviour. While theoretical work on intersubjectivity is relatively sophisticated, methodological approaches to studying intersubjectivity lag behind. Most methodologies assume that individuals are the unit of analysis. In order to research intersubjectivity, however, methodologies are needed that take relationships as the unit of analysis. The first aim of this article is to review existing methodologies for studying intersubjectivity. Four methodological approaches are reviewed: comparative self-report, observing behaviour, analysing talk and ethnographic engagement. The second aim of the article is to introduce and contribute to the development of a dialogical method of analysis. The dialogical approach enables the study of intersubjectivity at different levels, as both implicit and explicit, and both within and between individuals and groups. The article concludes with suggestions for using the proposed method for researching intersubjectivity both within individuals and between individuals and groups.     

The ratification of ILO Conventions and the provision of unemployment benefits: An empirical analysis

This article tests the relationship between the ratification of International Labour Organization (ILO) Conventions and the provision of unemployment benefits. Statistical tests focus on two related issues: why countries ratify ILO Conventions on unemployment benefits, and whether ratification influences government spending on unemployment benefits. The main findings are that democracy, region, income, and globalization are the main factors influencing why countries ratify ILO Conventions on unemployment benefits. In turn, the ratification of ILO Conventions is systematically associated with higher spending if countries have ratified more than two Conventions.

The role of time perspective in predicting Iranian farmers’ participatory-based water conservation attitude and behavior

ABSTRACT

In current perspective, farmers’ participatory behavior toward conservation of water resources (FPBCWR) is one of the most important strategies under water resource management in rural Iran. In this regard, understanding the predictors of farmers’ participatory-based water conservation behaviors and attitudes is gaining more importance than earlier. Among different dimensions of farmers’ participatory behavior, the potential of temporal frames was examined rarely. Thus, 322 Iranian farmers were investigated to examine the potential of their time perspectives in predicting their participatory-based water conservation behavior and attitude. According to the study results, the effects of present orientation on attitude and behavior were negatively significant, while the effects of future orientation on attitude and behavior were positively significant, whereas its effects (path coefficients) were stronger than present orientation effects. Past orientation did not have a significant effect on attitude, though attitude positively and significantly affected farmers’ participatory behavior. The results of causal analysis revealed that presented model accounted for 58% of variance in farmers’ ‘behavior’ and 42% of variance in “attitude.” In conclusion, a few demonstrable illustrations of policy implications are presented to enable utilizing the important findings and concluding results of this study that is linked further with water resource management domain.     

The Secondary Traumatic Stress Scale (STSS)

SUMMARY

The Secondary Traumatic Stress Scale (STSS; Bride, Robinson, Yegidis, & Figley, 2004) is an easy to administer 17-itemself-report measure of secondary trauma. Bride et al. (2004) reported a measure of three domains of traumatic stress specifically associated with secondary exposure to trauma: intrusion, avoidance, and arousal. The STSS was reported to have high levels of internal consistency reliability and indicated evidence of convergent, discriminant, and factorial validity. The purpose of this paper is to examine the reliability and validity of the STSS with a national, random sample of mental health social workers. To assess the fit of the data to the three-factor structure proposed by Bride et al., a confirmatory factor analysis was performed on data from 275 social workers who indicated exposure to client trauma. The model fit the data adequately although high factor intercorrelations strongly suggest a unidimensional scale. Subsequent confirmatory factor analysis of a unidimensional scale and a second order factor analysis yielded similar results. Findings indicate the need for further scale validation. Challenges remain for measuring and distinctly differentiating between secondary trauma symptoms of arousal, avoidance, and intrusion. Implications and suggestions for future research are discussed.     

Book Reviews

Critical appraisal of research studies forms a central role within the application and uptake of evidence‐based approaches within health and social care. While there are established checklists for evaluating quantitative research, this is not the case for qualitative research. This article outlines the process of developing an evaluative tool for qualitative studies, reflecting the uniqueness of the associated paradigm, and illustrates its use by reference to three qualitative research papers appraised within a systematic review of community‐based rehabilitation services. At its centre are concerns with the context of the study and the way the data are collected and analysed. Use of such an evaluative template opens the way for the quality of qualitative research to be judged in a systematic manner and for qualitative research to take its rightful place within debates over what works, where, when and how within health and social care policy and practice.
