农户土地流转意愿及其影响因素分析

我国现行的家庭联产承包责任制导致农户土地经营规模小,严重影响了土地资源利用效率的发挥。要解决这一问题必须借助农地流转这一途径来实现。然而如今土地流转过程中却出现了越来越多的制约因素,遇到了发展过程中的瓶颈期。通过调查问卷和农户访谈的方法,了解河北省Z市的土地流转现状,建立Logistic模型分析影响农户土地流转意愿的因素,运用SPSS软件进行回归分析,从而分别确定每一个相关因素对于土地流转的影响方向和影响大小。并针对分析结果提出相应的政策建议,这对于推进我国土地制度改革,保障民生,构建和谐农村和稳定社会有着十分重要而深远的意义。     

Risk Analysis of the Vessel Traffic in the Strait of Istanbul

The Strait of Istanbul, the narrow waterway separating Europe from Asia, holds a strategic importance in maritime transportation as it links the Black Sea to the Mediterranean. It is considered as one of the world's most congested and difficult-to-navigate waterways. Over 55,000 transit vessels pass through the Strait annually, roughly 20% of which carry dangerous cargo. In this study, we have analyzed safety risks pertaining to transit vessel maritime traffic in the Strait of Istanbul and proposed ways to mitigate them. Safety risk analysis was performed by incorporating a probabilistic accident risk model into the simulation model. A mathematical risk model was developed based on probabilistic arguments regarding instigators, situations, accidents, consequences, and historical data, as well as subject-matter expert opinions. Scenario analysis was carried out to study the behavior of the accident risks, with respect to changes in the surrounding geographical, meteorological, and traffic conditions. Our numerical investigations suggested some significant policy indications. Local traffic density and pilotage turned out to be two main factors affecting the risks at the Strait of Istanbul. Results further indicate that scheduling changes to allow more vessels into the Strait will increase risks to extreme levels. Conversely, scheduling policy changes that are opted to reduce risks may cause major increases in average vessel waiting times. This in turn signifies that the current operations at the Strait of Istanbul have reached a critical level beyond which both risks and vessel delays are unacceptable.     

Broadening the scope of ageing femininities on TV: the evolution of the older woman in two contemporary Catalan soap operas

The older woman has been an unacknowledged character in fiction up until recently, when it has become the focus of some studies in the interconnected fields of literary and cultural gerontology. Given their popularity, TV shows are especially powerful in the propagation of images of any form of identity; accordingly, they can be regarded as an interesting and highly effective artistic and socio cultural vehicle through which representations of old people and of old women in particular can be analysed and discussed. Despite the success of The Golden Girls in the 80s and the exponential ageing of the baby-boom generation, TV series have also continued to depict older female characters as either motherly figures, always looking after their families at any cost, or as devilish older women characterised by inappropriate sexualised appearance and sexual behaviour. In contrast to this predominant tendency, Six Feet Under (2001–2005) stands out as a significant exception. In this article, we argue that Six Feet Under is innovative in presenting the older woman through the central character of Ruth Fisher (Francis Connor) and through the interaction of Ruth Fisher with other women within her same generation which face ageing from different perspectives.     

“I Swear I Will Never Betray You”: Factors Reported by Spouses as Helping Them Resist Extramarital Sex in Relation to Gender,Marriage Length,and Religiosity

Studies suggest that married people frequently engage in intimate relationships with people other than their spouses, and the literature has extensively examined motives for doing so. However, less is known about what factors prevent spouses from engaging in extramarital sex. While investment theory, interdependence theory, and moral theories offer insights into this question, they have not been subject to much empirical research. We examine these theories in relation to several characteristics of individuals and couples: gender, length of the marriage, and religiosity. In two studies, 423 participants completed a questionnaire on the perceived importance of 29 reasons to resist the temptation for extramarital sex. Participants also reported the likelihood that they would engage in extramarital sex if the opportunity presented itself. Results show that being female, more religious, and married for less time were associated with greater expectations of refraining from extramarital sex when presented with a hypothetical scenario. Multiple hierarchical regression showed that among factors relevant to conscious decision making, moral standards and fundamental anxieties (fear of remaining alone) predict expectations of refraining from extramarital sex better than concerns about effects on the children or the other participant.

Social workers' attitudes to the law: an Israeli perspective

Doron I, Karpel M, Or‐Chen K. Social workers' attitudes to the law: an Israeli perspective
Int J Soc Welfare 2010: 19: 95–103 © 2009 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. In recent years, there has been a general shift towards integration and cooperation between lawyers and social workers, both professionally and ideologically. The goal of this study was to explore the general attitudes of social workers toward the law. The hypothesis was that, due to the recent legal and professional changes in Israel, social workers would express positive attitudes towards the law. For the purpose of this study, a closed questionnaire containing 25 statements regarding the law and its relationship to social work was used. The research population consisted of 202 social workers from Haifa and the Northern region of Israel. The findings of this study support the hypothesis that there is indeed a tendency to closer ideological and professional proximity between social work and the law in Israel. However, especially regarding courts and the litigation process, their attitudes in response to the statements were relatively less favourable.     

Narrating ageing: Deconstructing negative conceptions of old age in four contemporary English novels

Characters in their late sixties, seventies and even eighties have become the main protagonists and narrators in contemporary fiction. Narratives of ageing not only allow the reader to go into deep confines of an ageing protagonist, they also offer a detailed account of how these protagonists as well as the society around them deal with an increasing reality within the Western world, namely, that a demographic change is taking place and, thus, social and individual conceptions related to old age and ageing need to be revised and redefined. Novels such as Pat Barker's The Century's Daughter, Margaret Forster's Diary of an Ordinary Woman, Doris Lessing's The Diaries of Jane Somers and Rose Tremain's The Cupboard invite the reader to explore the ageing process, both at an individual and social level, through the stories their main protagonists narrate to a member of a younger generation. As a human complex process within a broader demographic change, stories of ageing succeed in helping young and old protagonists (and ultimately the reader) to reflect on the ageing process from a multiplicity of perspectives.     

创业网络、创业学习与新创企业成长

创业学习是新创企业成长的重要手段。尽管创业网络蕴含了大量可供新创企业学习的知识资源,然而少有研究对创业网络、创业学习与新创企业成长绩效之间的作用机制进行探索。本文整合社会资本理论与组织学习理论,构建了创业网络、创业学习与新创企业成长绩效关系的理论模型,并通过层次回归模型和结构方程模型对理论假设进行了实证检验。结果表明,探索式学习与利用式学习对成长绩效有正向影响;正式网络与非正式网络对成长绩效有正向影响;创业学习对创业网络与成长绩效之间的关系起中介作用。研究结论对社会资本理论与组织双元理论有重要贡献,对挖掘创业网络的学习价值并实现新创企业双元发展有重要启示。
