Abstract

Blitz argues for the necessity and possibility of political philosophy by uncovering its origins in the thought of Plato. By tracing its emergence from the political and moral, Blitz explains the nature of philosophy.  相似文献

Portugal dos Pequenitos (literally, ‘Portugal for the Little Ones’), a theme park built in Portugal as part of the Centenarian Commemorations of the Portuguese Nation of 1940, has been considered one of the most controversial pieces of Portuguese architecture in the 20th century. Designed between 1937 and 1962 by Architect Cassiano Branco, at the initiative of Bissaya Barreto, it features reproductions of uniquely typical Portuguese architecture built to a child's scale. It includes buildings from mainland Portugal, from the Azores and Madeira islands and from the colonial territories in Africa and Asia. The main aims of this paper are twofold: firstly, to frame Cassiano Branco's architecture in its specific context, in terms of historical contingencies and architectural controversies during the Estado Novo (New State) Portuguese dictatorship (1933–1974), and secondly, to assess the importance of Portugal dos Pequenitos as a laboratory for rehearsing an idyllic urban environment, applying hypothetical principles of national identity.  相似文献

This article considers current proposals for using electronic payments systems to promote financial inclusion — that is, to widen the availability of financial and monetary services in developing countries. While such systems can generate significant savings in the operation of monetary systems, payment services markets are typically uncompetitive and require regulatory and broader state interventions to ensure those savings are widely distributed. The use of those systems to broaden the reach of for‐profit lenders raises a number of concerns, as a growing literature has documented how microcredit initiatives in developing countries have resulted primarily in expansions in consumption credit to households, often under predatory terms. The authors advance two original arguments in this connection. First, the perverse results of many microcredit initiatives reflect the underdevelopment of the areas concerned: without broader development strategies, potentially transformative productive projects are rare and unprofitable to finance. In contrast, widespread unmet consumption needs ensure consumption credit offers lenders a profitable alternative business orientation. Second, and in light of this, electronic payments platforms can contribute to economic development by enabling the establishment of well‐regulated or public systems of electronic ‘narrow banks’ restricted from lending, but capable of widening access to affordable payments, savings and insurance services.  相似文献

In this paper we consider archaeology as a product of social interaction, and discuss how ancient Egyptian materiality has been an important part of identity building in Brazil. We begin by reviewing our theoretical setting, and suggest that a postmodern approach is most helpful to our goal of understanding the social context of the public uses of archaeology. The paper then turns to the trajectory of “Egyptomania” in Brazil, from the 19th century onwards, highlighting the importance of cultural movements such as Kardecism and Masonry in this trend. We argue that the use of Egyptian subjects in Brazil has connections with social inequality, racism, and gender biases. Finally, we present a case study on positive recent trends in the presentation of ancient Egypt in school textbooks which highlights critical approaches to the use of ancient Egyptian subjects in contemporary Brazil.  相似文献

ABSTRACT A common problem with spatial economic concentration measures based on areal data (e.g., Gini, Herfindhal, entropy, and Ellison‐Glaeser indices) is accounting for the position of regions in space. While they purport to measure spatial clustering, these statistics are confined to calculations within individual areal units. They are insensitive to the proximity of regions or to neighboring effects. Clearly, since spillovers do not recognize areal units, economic clusters may cross regional boundaries. Yet with current measures, any industrial agglomeration that traverses boundaries will be chopped into two or more pieces. Activity in adjacent spatial units is treated in exactly the same way as activity in far‐flung, nonadjacent areas. This paper shows how popular measures of spatial concentration relying on areal data can be modified to account for neighboring effects. With a U.S. application, we also demonstrate that the new instruments we propose are easy to implement and can be valuable in regional analysis.  相似文献

Abstract. Given sound theoretical underpinnings, the random utility maximization‐based conditional logit model (CLM) serves as the principal method for applied research on industrial location decisions. Studies that implement this methodology, however, confront several problems, notably the disadvantages of the underlying Independence of Irrelevant Alternatives (IIA) assumption. This paper shows that by taking advantage of an equivalent relation between the CLM and Poisson regression likelihood functions one can more effectively control for the potential IIA violation in complex choice scenarios where the decision maker confronts a large number of narrowly defined spatial alternatives. As demonstrated here our approach to the IIA problem is compliant with the random utility (profit) maximization framework.  相似文献

The history of cross vaults began almost 2,000 years ago with a widespread use during the Middle Ages and Renaissance, becoming nowadays one of the most diffused and fascinating structural typologies of the European building cultural heritage. However, conversely to the undeniable excellence achieved by the ancient masons, the structural behavior of these elements is still at the center of the scientific debate. In this regard, with the aim of reviewing the knowledge on this subject as a concise and valuable support for researchers involved in conservation of historical buildings, with a focus on design rules and structural analysis, the present study firstly introduces the cross vaults from a historical perspective, by describing the evolution of the main geometrical shapes together with basic practical rules used to size them. Then, the article deals with the subsequent advancements in structural analysis methods of vaults, until the development of modern limit analysis.  相似文献

Timber-framed wall buildings are seen all over Europe, especially in seismic regions, given its adequacy to resist earthquakes. The “Pombalino” buildings, developed after the great 1755 earthquake that destroyed Lisbon, constitute one of the best examples of historic seismic-resistant structures based on timber-framed masonry walls. The research presented in this article aimed at experimentally evaluating the seismic behavior of the “Pombalino” buildings. The experimental program was based on extensive dynamic testing on sub-structures of typical “Frontal” walls (the timber masonry walls), carried out at the LNEC (the Portuguese National Laboratory of Civil Engineering) shaking table. The tests comprised (a) seismic tests, in which the seismic action was applied with increasing amplitude in one direction; and (b) dynamic identification tests, aiming at evaluating the dynamic properties of the sub-structures and their evolution with damage accumulation.  相似文献
