A key challenge to theories of long-run economic growth has been linking the onset of modern growth with the move to modern fertility limitation. A notable puzzle for these theories is that modern growth in England began around 1780, 100 years before there was seemingly any movement to limit fertility. Here we show that the aggregate data on fertility in England before 1880 conceals significant declines in the fertility of the middle and upper classes earlier. These declines coincide with the Industrial Revolution and are of the character predicted by some recent theories of long-run growth.  相似文献

Since the implementation of the Temporary Assistance for Needy Families (TANF) program in late-1996, welfare rolls have declined by more than half. This paper explores whether improvements in the economic well-being of children have accompanied this dramatic reduction in welfare participation. Further, we examine the degree to which the success or failure of welfare reform has been shared equally among families of varying educational background. We analyze data from the March Current Population Surveys (CPS) over the years 1988 through 2001. Specifically, we link data for families with children who are interviewed in adjacent years and determine whether their economic circumstances either improved or deteriorated. We use two alternative approaches to address this general issue: a variety of regression models and a difference-in-differences methodology. These approaches provide consistent answers. In a bivariate framework TANF is associated with higher incomes; but this association becomes insignificant in the presence of business cycle controls. We also determine that children who were poor at an initial time period benefit differently, depending on their parents' educational attainment level. Poor children with parents who do not have a high school degree are significantly worse off in the TANF era, relative to the era prior to welfare reform, than are poor children of more educated parents.  相似文献

During the Second World War (1939-1945), South African military authorities employed various regimes to mould white South African soldiers as citizens of a particular type. These coincided broadly with traditions of racial statehood identified by David Goldberg, and included attempts at ideological control – through the liberal Army Education Scheme, a compulsory adult education project – as well as disciplinary interventions, which concentrated on soldiers' sexuality. The ways that ordinary soldiers responded to these divergent discourses reminds us that whiteness in a racial state was elaborated not just from above, but also below. This observation raises some cautionary points for the writing of 'post-social' history, and just as it demands that ordinary servicemen's actions, experiences and ideologies need to be related to the state and other modes of power, it reaffirms Geoff Eley's appeal for a 'new history of society'.Lines of investigation that explore attempts to educate, discipline and control white soldiers begin to challenge some of the conventional periodizations of SA history, particularly the notion that South Africa's 1940s represented an optimistic 'world of possibilities'.  相似文献

In recent years, there has been an increasing focus among childhood researchers on the concept of children's agency, or children as social actors, within research. The argument for the focus on children as ‘agents’ has commonly critiqued an earlier dominant tradition of research, whereby children had been positioned as passive objects of investigation, with their capacity for social agency largely ignored.This paper provides a theoretical and methodological exploration of the concept of children's agency in the research process. The authors outline conceptual developments that have contributed to the increased focus on children's agency and discuss how this focus has influenced research methods, both in terms of counting children in and researching collaboratively with them. Key elements of a methodological framework for promoting children's agency in collaborative research are outlined and some of the contextual obstacles to the implementation of this framework are discussed, in particular those encountered in attempting to ‘balance power relations’ between adults and children. The facilitation by adults of children themselves as researchers is identified as a possible way forward.The paper concludes with a brief discussion on the extent to which the acknowledgement of children's agency in research may lead to more inclusive policy practices.  相似文献

We present theoretical results for large-file distribution on general networks of known topology (known link bandwidths and router locations). We show that the problem of distributing a file in minimum time is NP-hard in this model, and we give an O(logn) approximation algorithm, where n is the number of workstations that require the file. We also characterize our method as optimal amongst the class of “no-link-sharing” algorithms.  相似文献

Since 1999 New Zealand has seen the election of a series of Labour-led governments committed to a social policy framework of social development. This article outlines the background to the emergence of social development, tracing its antecedents in the neo-liberal administrations of the 1990s. The social development framework consists of commitments around economic development, human capital development, family development and politico-administrative redevelopment. Taking the position that reforms must be seen as concrete policy mechanisms and as discursive cues and conceptual apparatus, the article offers a comparison and critique. First, it identifies the continuities and contrasts with the previous neo-liberal framework of minimal social policy; and second, it begins the process of critically interrogating the potential citizenship implications of social development.  相似文献

Given that more people 'permanently' migrate today than in the past, migration has taken on a heightened profile internationally. Such mobility raises fundamental social policy questions of entitlement and (re)negotiation of caregiving obligations and arrangements. Social policy has traditionally approached problems and developed responses within the confines of the nation-state and faces difficulties in recognising and addressing issues arising from mobility. Migration contributes to family being 'stretched' beyond national boundaries to become dispersed, global or transnational families. This article focuses attention on one dimension of transnational living – older people as members of transnational families. The combination of increasing population mobility and the elongation of new post-retirement life-stages is resulting in a set of pressing social policy issues. It explores immigration, pension eligibility and portability, and social services and caregiving issues. To illustrate these issues the article draws on New Zealand's diverse transnational family forms and experience.  相似文献

Nine‐month‐old infants were presented with an engaging and challenging task of visually tracking and reaching for a rolling ball that disappeared and reappeared from behind an occluder. On some trials, the infant observed the experimenter place a barrier on the ball's track; the barrier remained partially visible above the occluder throughout the remainder of the trial. When the task involved only predictive tracking, infants' anticipatory gaze shifts were faster when no barrier was present. When the task involved both tracking and reaching, there were more reaches when no barrier was present. If the infant reached, the timing and extension of the reach and the accompanying gaze shift did not differ with regard to the barrier. Because catching the ball was quite difficult for these infants, task demands interfered with the integration of visual information and visuospatial reasoning about the barrier with the reaching action.  相似文献

The perceptions of ten social workers regarding their practice within the organisational context of Saudi hospitals were examined using semi-structured interviews. A qualitative analysis employing a thematic approach informed by grounded theory was undertaken and produced the two broad interrelated themes – organisational structure and management processes – which highlighted an overarching concern of an 'us and them' division between social workers and management. The discussion shows how solutions to the perceived difficulties of social workers in hospital settings require a consideration of how partnership between practitioners and management personnel may be enhanced.  相似文献
