High and unstable inflation rates have prevailed in Brazil during the period 1985-92. All attempts to stabilize the economy have failed and ‘living with inflation’ has become politically feasible. The structure of the financial market in general, and financial adaptation mechanisms in particular, have played a crucial role in implementing and maintaining this political-economic option. Financial adaptation mechanisms sway the management of monetary and fiscal policies, with a direct influence on the credibility of macroeconomic policy announcements. More importantly, distributive asymmetries generated by those financial instruments, in association with differences in political motivation for different groups in the society, have created a stalemate regarding stabilization efforts. This article argues that, for the Brazilian case, the positive economics literature has failed to explain the inflationary phenomenon because it has not considered financial adaptation as an important linkage between political motivation of certain groups in the society and the correspondent desirable economic outcomes. The validation of social-economic objectives of certain classes became an important raison d'être of financial adaptation. Consequently, change of inflationary regimes carries costs and benefits far beyond those implied by fiscal reform alone. 相似文献

Stone masonry walls of ancient buildings have reasonable resistance to vertical loads but lower resistance to shear forces and reduced tensile strength. However, to achieve such compressive strength the masonry must not disaggregate when subjected to loading. This can be achieved if during the construction of the walls larger stones, usually referred as “through stones”, are used, spanning the thickness of the wall, making it possible to improve the transverse confinement of the masonry. For rehabilitation projects and structural reinforcement of such buildings, the transverse confinement can be achieved by fixing steel elements perpendicular to the wall. This confinement technique is often part of a more comprehensive rehabilitation solution, which includes the application of mortar or concrete reinforced layers applied to the wall surface.
This article presents results of an experimental research on material properties and mechanical characterisation of stone masonry specimens strengthened by two transverse confinement solutions (independent steel reinforcing rods and continuous steel ribbons wrapping the specimen). Specimens were tested under compression and compression and shear loadings.
This experimental work is part of a major research project to study the mechanical behavior of URM and strengthened walls, and the characteristics of the building materials of such specimens. 相似文献

This article claims that welfare states modelled on a contributory basis and with a system of entitlements that assumes stable two-parent families, a traditional breadwinner model, full formal employment and a relatively young age structure are profoundly flawed in the context of present-day challenges. While this is true for affluent countries modelled on the Bismarckian type of welfare system, the costs of the status quo are even more devastating in middle-income economies with high levels of inequality. A gendered approach to welfare reform that introduces the political economy and the economy of care and unpaid work is becoming critical to confront what may very well become a perfect storm for the welfare of these nations and their peoples. Through an in-depth study of the Uruguayan case, the authors show how the decoupling of risk and protection has torn asunder the efficacy of welfare devices in the country. An ageing society that has seen a radical transformation of its family and labour market landscapes, Uruguay maintained during the 1980s and 1990s a welfare state that was essentially contributory, elderly and male-oriented, and centred on cash entitlements. This contributed to the infantilization of poverty, increased the vulnerability of women and exacerbated fiscal stress for the system as a whole. Furthermore, because of high levels of income and asset inequality, the redistribution of risk between upper- and lower-income groups presented a deeply regressive pattern. The political economy of care and welfare has begun to change in the last decade or so, bringing about mild reforms in the right direction; but these might prove to be too little and too late. 相似文献

Portugal is arguably the European nation with the longest experience with “colonialism” in a variety of configurations, historical moments, and geographical contexts. Yet, given its perennially peripheral status from a geopolitical and economic standpoint, the Portuguese (post-)colonial experience has not been an object of attention outside of the field of Lusophone Studies. This essay provides a brief historical overview to understand the breadth and depth of the Portuguese (post)colonial experience; offers a conceptual map of Portuguese postcoloniality where ideologies of affect and exceptionalism such as Lusotropicalism play a key role; highlights the centrality of immigration for an understanding of Portuguese society — particularly African immigration and its nexus with the history of colonialism and racism that reverberates in national debates around race, ethnicity, and interculturality; provides a brief account of the rise of an Afro-Portuguese culture; and presents short readings of Portuguese cinematic texts that exemplify ethical and aesthetic praxes bringing marginalized black subjects to the center of representation in the quest for social and cultural citizenship. 相似文献

Trade and location theory identifies forces that could leadto locational dispersion (comparative advantage) or locationalconcentration (scale economies) in the face of globalizing markets,each with different consequences for specialization and theadjustment costs associated with integration. However, theseforces can play themselves out in very complex ways if locationalchange principally affects intermediate production. Moreover,effects of history may be important, if locational patternswhich exist prior to integration reflect either strong externaleconomies or, as we argue, strong institutionalized capacitiesto respond to more open markets. This could especially be thecase in the context of Europe, whose territories are generallyless specialized than the states of the USA. To see how thesedifferent effects are operating today, empirical measurementis required. Using a data set which allows changes in locationaldistribution of manufacturing industries in the OECD to be measured,we show that Europe does not seem to be Americanizingits economic geography. Many sectors are actually spreadingout in Europe, implying that the effects of history have remainedstrong up to this point. Specialization increases are weak inmost European economies as well. The OECD has a more complexpicture of spread and concentration. Some of the implicationsfor further research on agglomeration, intra-industry trade,and integration are brought out in the conclusion. 相似文献
