The authors combine historical and sociological institutional analysis to show that despite the political and socio‐economic transformation in 1990s, the institutional development during and before the communist era provides the best explanation for current childcare policies in Central Europe. While most authors have concentrated on policy changes that have taken place in the region since 1989, this article concentrates on the historical roots of these policies and shows that today's policies are highly influenced by a certain dynamics that had already emerged under communist rule. It shows that a historical institutional approach, which analyses the ‘gendered logic of appropriateness’ and policy legacies at various critical junctures, can explain why family policies in Central Europe had already begun to differ during the communist era, why these main differences continue and why even the changes that have taken place follow logically from historical‐institutional developments.  相似文献

This article describes the differential mortality of Argentina’s disability pension beneficiaries during the 2015–16 period, based on National Social Security Administration (Administración Nacional de la Seguridad Social – ANSES) payment records. It compares data for those with an assessed disability with overall population data, as well as with available international data (from Canada, Chile, Mexico, and the United States of America). In addition to breaking down mortality rates for people with disabilities by age and sex, it also factors in duration of benefit, establishing an inverse correlation between benefit duration and mortality.  相似文献

The uneven development of minimum incomes in Spain is one of the factors that explain the significant differences in the poverty indicators that characterize the Spanish regions, generally in favour of the territories most committed to these policies (Basque Country, Navarra and Asturias). However, there are other aspects that deserve some consideration when interpreting the specific method of developing minimum incomes in southern Europe. One aspect has to do with the differing dynamics of countries, such as Spain and Italy, which have opted for a decentralized regional model. In this regard, the regional autonomous initiative of the Basque Country played a decisive role in promoting minimum income programs in the late 1980s. Without its leadership in the launch of the regional minimum income policy, Spanish trade unions would probably not have opted for this method as a mechanism for combating poverty in the 1990s. No Italian region went on to play this driving role at that time. This article analyses the ideological foundations of the Basque minimum income policy introduced in the late 1980s and which grew significantly before and during the crisis that started in 2007-2008. It examines the dominant political narrative on this issue by analysing the discourse of some of the key nationalist leaders involved in the birth and development of the minimum income scheme. The approach shows that the experience of social decline linked to industrial restructuring processes was instrumental in the construction of the nationalist narrative.  相似文献

This article examines the extent to which the Australian and UK social security systems meet their legal obligations to provide basic relief to citizens in need. Conditionality and “mutual obligation” are at the core of both the UK and Australian social security systems and are based on the concept of moral hazard, the goal being to ensure that claimants do not consider living on benefits to be preferable to engaging in paid work. Yet, we argue that the element of “mutuality” is missing in both systems; welfare claimants are subject to myriad conditions and obligations, whilst the state operates free of any legal responsibility to provide even basic relief to those in need, to prevent or alleviate extreme poverty and destitution. We outline the extent to which Australian and UK social security laws require governments to relieve destitution, examining both domestic and human rights law. We conclude that legal protections are weak and that both systems fail to meet the basic conditions of humanity toward their citizens. On this basis, we argue that such failings demonstrate a lack of integrity which undermines the standing of both the UK and Australia to invoke a claim of moral hazard to defend claimant conditionality.  相似文献

Semi-on-line algorithms for the bin-packing problem allow, in contrast to pure on-line algorithms, the use of certain types of additional operations for each step. Examples include repacking, reordering or lookahead before packing the items. Here we define and analyze a semi-on-line algorithm where for each step at most k items can be repacked, for some positive integer k. We prove that the upper bound for the asymptotic competitive ratio of the algorithm is a decreasing function of k, which tends to 3/2 as k goes to infinity. We also establish lower bounds for this ratio and show that the gap between upper and lower bounds is relatively small.  相似文献

In this paper, we describe a series of laboratory experiments that implement specific examples of a general network structure. Specifically, actions are either strategic substitutes or strategic complements, and participants have either complete or incomplete information about the structure of a random network. Since economic environments typically have a considerable degree of complementarity or substitutability, this framework applies to a wide variety of settings. We examine behavior and equilibrium selection. The degree of equilibrium play is striking, in particular with incomplete information. Behavior closely resembles the theoretical equilibrium whenever this is unique; when there are multiple equilibria, general features of networks, such as connectivity, clustering, and the degree of the players, help to predict informed behavior in the lab. People appear to be strongly attracted to maximizing aggregate payoffs (social efficiency), but there are forces that moderate this attraction: (1) people seem content with (in the aggregate) capturing only the lion's share of the efficient profits in exchange for reduced exposure to loss, and (2) uncertainty about the network structure makes it considerably more difficult to coordinate on a demanding, but efficient, equilibrium that is typically implemented with complete information.  相似文献

This study seeks to explain the influence of quality management on the relationship between open innovation and performance. We propose that, to contribute to open innovation performance, an organisation’s commitment to quality improvement must rely on the combination of its own resources and capabilities and its open innovation partners’ resources and capabilities. Specifically, we examine the moderating role of an interorganisational IT infrastructure and the complementarity of learning styles among an organisation committed to quality improvement and its supply network. Using data from 270 managers of European firms, our results show that the negative effects of quality management on open innovation performance can be overcome by complementing the organisation’s learning style with that of its open innovation partner, particularly, its supply network, and, most importantly, obtaining information technologies compatible with those of its supply network members.  相似文献
