In this article the opportunity structures of New York City and Amsterdam for organized squatting are compared. New York City knew two distinct squatting waves, with an intermission of several years. The literature on US urban movements predicts transformation through cooptation and repression. Only the first wave, in which housing activists used squatting as a tactic, fits this prediction. The second wave of squatting in New York City, and squatting in Amsterdam in general, escaped cooptation because they involved a squatters' movement proper, in which squatting was not only a tactic but also central to its existence. Compared to Amsterdam, squatting in New York was hampered by technical difficulties and political isolation. Stricter protection of private property made New York squatters restrict themselves to publicly‐owned abandoned buildings. Turf conflicts tended to develop on the neighbourhood level when these buildings were later claimed for the development of low‐income housing. In Amsterdam this type of conflict was rare because of the broad support for low‐income (re)development. Instead, Amsterdam saw citywide protest directed at the real estate sector and municipal authorities. Cet article compare la structure des opportunités des villes de New York et Amsterdam concernant les squats organisés. New York a connu deux vagues de squattage séparées de plusieurs années. Les textes sur les mouvements urbains aux Etats‐Unis prévoient une mutation par cooptation et répression. Seule la première vague, pour laquelle les militants en faveur du logement ont utilisé le squattage comme tactique, répond à cette prédiction. La seconde vague d'opérations à New York, et celles d'Amsterdam en général, ont échappéà la cooptation, car il s'agissait de mouvements de squatters à proprement parler, où le squat n'était pas seulement une tactique mais surtout un fondement de leur existence. Comparéà Amsterdam, le squattage à New York s'est heurtéà des problèmes techniques et à un isolement politique. La protection plus stricte de la propriété privée a forcé les squatters new‐yorkais à se limiter aux bâtiments publics abandonnés. Des luttes de territoires ont eu tendance à se développer entre voisins lorsque ces bâtiments ont ensuite été réclamés pour aménager des logements à faible loyer. A Amsterdam, rare fut ce genre de conflit grâce au vaste soutien favorable au (ré)aménagement social; au contraire, une protestation générale s'est élevée à l'encontre du secteur immobilier et des autorités municipales.  相似文献

The purpose of this article is to describe how households in Novgorod the Great, Russia, deal with food provision in everyday life. The study focuses on changes experienced in food provision and consumption in Russian society, in order to illustrate how households respond to the transformation towards a market economy. The study reflects women's perspective on food provision. Students from Novgorod the Great visited 105 households and asked the women in the household to answer a questionnaire. Results from the study show that in order to cope with changes in society related to economic reforms, Russian households had changed both their food consumption and food production patterns. There was no big difference between urban and rural households. Nearly all of the households were self‐sufficient in the provision of vegetables and potatoes. Many households had a ‘dacha’ (plot), where they produced most of what they needed. Among the changes experienced during recent years (i.e. during the end of the 1990s), a decade after perestroika was initiated, households mentioned the rise in food prices and the decrease of income. Households reported that they consumed less fruit and/or meat. Some households also mentioned that the quality of nourishment had decreased, thereby indicating lower general quality, lower nutrition value, or less healthy foodstuffs.  相似文献

Despite the prevalence of elective business ethics courses, little research has sought to explain and predict why some students enroll in these courses and while others do not. Using the theory of planned behavior (Ajzen and Madden, 1986) as a theoretical foundation, 178 graduate students in Ireland were surveyed about their intention to sign up for an elective ethics class. Their behavior was measured two months later. The results reveal the power of the theory of planned behavior to explain and predict who takes elective ethics classes.Donna M. Randall is an associate professor and chair in the Department of Management and Systems at Washington State University. Her research interests include business ethics, organizational commitment, and reproductive risk in the work place. Her work has appeared inJournal of Business Ethics, Decision Sciences, Academy of Management Review, Journal of Vocational Behavior, Journal of Business Research, and others.  相似文献

Asset market hangovers and economic growth: the OECD during 1984-93   总被引:1,自引:0,他引:1  
Asses prices and investment were unusually weak throughout theindustrial world during the early 1990s. This paper highlightsthis stylized fact, and connects it with another: in most ofthe industrial world, asset markets boomed for several yearsbefore collapsing around 1989. The paper suggests that assetmarket bubbles during the late 1980s may have left the industrialworld with an 'asset market hangover' in the early 1990s, inthe form of sluggish asset markets and investment. Empiricalsupport for this hypothesis is provided based on cross-countrydata for equity and real estate markets in most industrial countries.We suggest that financial market developments not justifiedby fundamentals can substantially affect real activity.  相似文献

This article surveys recent research of the Spanish colonial era in the Philippines since the late eighteenth century. While highlighting imperfections in our understanding, the article establishes the parameters with which the Philippine economy entered the twentieth century. It outlines the intensification of Spanish colonial rule through changes in the taxation system, particularly the expansion of forced tobacco cultivation until its abolition in 1882. Since then, the Spanish set out to further change and intensify colonial rule but contradictions in the system of colonial rule caused the effort to come to an abrupt end in 1898.  相似文献

The number of firms using alliances as part of their corporate venturing or market entry strategies has surged over the past decade. Three common reasons cited for pursuing alliances are technology convergence, market access and alliance partners' complementary resources. This paper contrasts the alliance strategies of HP and IBM, two major competitors in electronic services (i.e. Internet-based 'e- service') businesses, using the Familiarity Matrix as a display tool to portray the strategies. Whereas the HP strategy is to attempt to establish its technology infrastructure as the standard e-services infrastructure on the Internet, IBM aims to position its IBM Global Services, rather than its technology, at the center of this ecosystem.  相似文献

This paper studies financial intermediation in a general equilibriumoverlapping generations model. Indivisible investment projects combine withinformational imperfections to create a (hidden action) moral hazard problemand introduce a role for third-party monitoring. Agency costs at theintermediary level are also considered. Under some conditions, monitors canbe viewed as banks facing a non-trivial portfolio diversification problem.Equilibria are derived in which a large nationwide bank coexists with anumber of community-regional banks, a structure of strong empiricalrelevance. Policies such as a mandatory reserve requirement are shown tohave substantial effects on the levels of investment in the economy.  相似文献

This paper examines monthly wage data collected by the Agro Economic Survey from seven villages in the Cimanuk River Basin of West Java, where data on agricultural and non-agricultural wages and prices of nine essential commodities were collected twice monthly between 1977 and 1983. Movements in money wages deflated by both the rice price and a weighted index of basic commodities are analysed in detail and differences between lowland and upland villages are discussed.  相似文献
