Mobility is one of the most important constituents of everyday life, yet it is rarely studied historically and we know little of how it relates to changing family and life course constraints. Using data drawn from oral life histories, this article examines changes in everyday mobility over the past 60 years focusing both on changes over the life course and on the constraints imposed by family structures. We argue that, like residential migration, daily mobility has been closely related to the life course, with women especially affected by the constraints of motherhood and marriage. However, there is evidence that such constraints have changed over time, and that some older people today enjoy more mobility than they did at earlier life stages. We also argue that the independent mobility of children was closely related to the family structure in which they were situated, but that these constraints have changed much less over the past 60 years. The oral testimonies examined also highlight the variability of mobility experiences and the role of the individual in fashioning mobility behavior.  相似文献

This study, based on work in six villages, seeks insights into the likely effect of the introduction of prospective land‐, water‐, and crop‐management technologies, being researched at the International Crops Research Institute for the Semi‐Arid Tropics, on the existing village labour‐use patterns in one major relevant region: peninsular India. Explicit attention is given to the similarities and differences between small and large farms and their relevance to the adoption of the prospective new technologies.

Regional variation in labour utilisation reveals a tremendous employment‐creating potential in the existing tank and well irrigation systems in the Alfisols of peninsular India. The prospective technologies should increase employment, compared with existing technologies, by at least 100 per cent in the Alfisols and by over 300per cent in the deep Vertisols— but with some increase in the seasonal variability of labour demand. Given the existing availability of labour, there will be, with the improved watershed technologies, major farm labour bottlenecks. These should eventually generate increased wage rates and employment potentials. However, even temporary adverse effects on the timelessness of operations could be critical to the success of a double‐cropping and/or intercropping technology aiming at greatly increased yields. This would create demands for selective mechanisation, for example, of threshing.  相似文献

Abstract

According to Ward (2000), cognitive distortions emerge from “implicit theories” (ITs). Ward and Keenan (1999) established a typology of the ITs of child molesters in which they classified existing knowledge on their cognitive distortions into five categories: “entitlement”, “nature of harm”, “uncontrollability”, “child as sexual being” and “dangerous world”. The purpose of this research was to examine whether the cognitive distortions of child molesters are encapsulated fully by these five categories of ITs. Semi-structured interviews were conducted with 20 convicted francophone child molesters and their cognitive distortions were analysed. Results indicate that six ITs were present in this sample. “Entitlement”, “nature of harm” and “uncontrollability” were identical to those of Ward and Keenan. “Child as sexual being” and “dangerous world” were present, but varied from their original versions. A new IT emerged, which we called “child as partner”. We discuss these findings in comparison to their original versions.  相似文献

Abstract

We still poorly understand why Silicon Valley has originated so many breakthrough innovations and large companies. The durability of Silicon Valley's innovative competence over the last seventy years also needs more explanation. The failure of several policy-makers around the world to reproduce the Silicon Valley cluster reveals the misunderstanding of the innovative dynamic in Silicon Valley. This study uses complex network theory – CNT (Barabási, Newman & Watts, 2006; Jen, 2006; Thompson, 2004a) to analyse the complex innovative capability of Silicon Valley and to understand the heterogeneity of agents and the multiplexity of ties that support creation and development of high-tech start-ups. As proposed by Barabási (2002, p. 200), we view the economy as a complex network, whose nodes are companies and whose links represent the various economic and financial ties connecting them. Innovation and entrepreneurship are understood as resulting from the interactions of numerous economic agents.

In a systemic perspective, by definition, the presence of a specific agent in a network induces specific interactions with other agents that could not take place if this agent were not there. Thus, the diversity of agents influences the dynamics of the system. The presence of venture capital (hereafter VC) firms in an innovative cluster opens potential specific interactions with other agents in the network (universities, large companies, laboratories) that determine a particular dynamic of innovation. In this perspective, what is distinctive about Silicon Valley is its complete and robust complex system of innovation supported by social networks of interdependent economic agents in which the VC firms have a specific function. Our perspective examines five different contributions of VC firms to Silicon Valley: financing, selection, collective learning, embedding and signalling. These five functions are different ways for the VC firms to interact with the other members of the complex network of innovation and to support the robustness of the system.  相似文献

The high political salience of youth unemployent in European countries is not matched by a prompt coherent and concerted response by trade unions. In particular, measures to ease the transition from school to working life have evoked very mixed reactions. Aspects of the national trade union movements themselves are important determinants of this situation: political alignment and the legitimacy of their policy‐making role; financial, membership, and organisational resources; the structure and practice of collective bargaining, and finally, relations with other organisations representing youth. The three countries examined ‐ West Germany, Britain and France ‐ show that although the trade unions concerned are aware of the problems, they differ in their capacity to take effective action.  相似文献

Abstract

This paper draws upon and develops Paul Rabinow's concept of biosociality to analyse how the field of gambling research, the facts about gambling addiction and the politics of gambling regulation are in the process of transforming one another as the US gambling industry has begun to provide large amounts of funding for scientists and clinicians working on gambling problems. In particular, the paper focuses on the political economy of research that suggests that the negative consequences associated with gambling are not just social problems, but neurobiological ones. The paper introduces the notion of ‘biopolitical capital’ in order to describe how the gambling industry invests in particular kinds of research which are more likely to yield results that can be mobilized to support particular kinds of approaches to dealing with the social and personal problems associated with gambling.  相似文献

We describe an original case of drowning in a wax tank in an industrial setting. The causes of death were multiple, with the association of drowning, mechanical asphyxia, and extensive superficial burns. To our knowledge, it is the first report of drowning in wax, and only 7 previous related observations of drowning in industrial environments were reported in the international literature. These accidents are more often fatal, with multiple associated causes of death due to the incriminated media. Although exceptional, these serious accidents must be prevented in potentially risky industries.  相似文献
