Theorizing the Politicizing City   总被引:2,自引:0,他引:2       下载免费PDF全文
This introductory symposium article develops a framework for an urban political reading and a theorization of urban uprisings. We argue that there is a need to foreground the notion of the urban political as central to the theoretical and practical demands of urban research today. First, we revisit critical urban theory in light of recent urban insurrections and point out a lack of sustained theoretical engagement with the political. Second, based on this critique, we argue for what we call a ‘re‐centring of the urban political' to rethink urban theory in ways that consider the city as a site of political encounter, interruption and experimentation, even when, or perhaps especially when, these ways fall outside institutional forms or lack the organizational form or legitimacy of social movements. Thus, we attempt to place politics at the heart of radical urban political theory and practice today in order to make sense of urban subjects, events and claims that elude established government practices and institutionalized structures.  相似文献

One of the distinguishing features of Belgian economics is that, from the early 1920s, so many of Belgium's best economists pursued postgraduate studies at top American universities, a case of ‘temporary’ migration. This was made possible by the fellowships granted by the Commission for Relief in Belgium, a legacy of the First World War. After a stay in the US of a few years, most returned to Belgium. However, they maintained strong links with the US. Also, they tried to recreate in Belgium the most valuable elements of their American experience. It would lead to a strong and early Americanization of Belgian economics. Moreover, they were at the forefront of several initiatives to organize economics on a European scale, such as the European Economic Review and the European Economic Association.  相似文献

We discuss the strengths and weaknesses of five alternative innovation indicators: R&D, patent applications, total innovation expenditure and shares in sales taken by imitative and by innovative products as they were measured in the 1992 Community Innovation Survey (CIS) in the Netherlands. We conclude that the two most commonly used indicators (R&D and patent applications) have more (and more severe) weaknesses than is often assumed. Moreover, our factor analysis suggests that there is little correlation between the various indicators. This underlines the empirical relevance of various sources of bias of innovation indicators as discussed in this paper.  相似文献

Despite evidence that information technology (IT) has recently become a productive investment for a large cross-section of firms, a number of questions remain. Some of these issues can be addressed by extending the basic production function approach that was applied in earlier work. Specifically, in this short paper we: 1) control for individual firm differences in productivity by employing a ‘firm effects’ specification, 2) consider the more flexible translog specification instead of only the Cobb-Douglas specification, and 3) allow all parameters to vary between various subsectors of the economy.

We find that while ‘firm effects’ may account for as much as half of the productivity benefits imputed to IT in earlier studies, the elasticity of IT remains positive and statistically significant. We also find that the estimates of IT elasticity and marginal product are little-changed when the less restrictive translog production function is employed. Finally, we find only limited evidence of differences in IT's marginal product between manufacturing and services and between the ‘measurable’ and ‘unmeasurable’ sectors of the economy. Surprisingly, we find that the marginal product of IT is at least as high in firms that did not grow during 1988–1992 sample period as it is in firms that grew.  相似文献

The organizational design literature strongly supports the notion of “structure follows strategy”, and suggests that a misfit between the two has a negative effect on performance. Building on this line of argument, we examine to what extent the (mis)fit between purchasing strategy and purchasing structure impacts purchasing performance. We focus on cost and innovation purchase category strategies, and examine how the deviation from an ideal purchasing structure defined along three dimensions (centralization, formalization, and cross-functionality) impacts purchasing performance. Analysing data collected from 469 firms in ten countries, we demonstrate that a strategy-structure misfit negatively impacts purchasing performance in both cost and innovation strategies. We also find that purchasing proficiency is a mediator in this relationship between misfit and performance. Our findings aid managerial decision making by empirically validating the necessity of having the right purchasing structure for successfully executing different purchasing strategies.  相似文献

Scholars in our field, Operations and Supply Chain Management (OSCM), are under high pressure to show research productivity. At most schools, this productivity is measured by the number of journal articles published. One possible response to such pressure is to improve research efficiency: publishing more journal articles from each data collection effort. In other words, using one dataset for multiple publications. As long as each publication makes a sufficient contribution, and authors ensure transparency in methods and consistency across publications, generating more than one publication from one data collection effort is possible. The aim of this Notes and Debates article, however, is to draw attention to inappropriate reuse of empirical data in OSCM research, to explain its implications and to suggest ways in which to promote research quality and integrity. Based on two cases of extensive data reuse in OSCM, eighteen problematic practices associated with the reuse of data across multiple journal articles are identified. Recommendations on this issue of data reuse are provided for authors, reviewers, editors and readers.  相似文献

Vertical specialization (VS) is quantified by the VS share, which measures the average import content per dollar of exports. A characteristic of China’s export trade is its strong dependence on assembly and processing activities. To take proper account of this, China’s VS shares should explicitly distinguish processing export production from other production. We estimate China’s annual VS shares from 2000 to 2012—the latest year for which a special input–output table is available that makes such an explicit distinction. We find that VS shares increased from 2000 to 2004 and subsequently started to decrease. To explore why it has declined, we introduce a new structural decomposition approach. We find that the decrease of the VS share appears to have been driven mainly by the substitution of imported intermediates by domestic products. This occurred in particular in the production of exports, which implies an upgrading of China’s position in global value chains.  相似文献

Many companies experience difficult situations as a result of their selected strategy. Strategic management theories implicitly assume that companies have a free choice in setting their strategy. Hence, when companies experience difficult situations this is because of management inadequacy. It is questionable whether companies always have a free choice. This research examines this issue by examining the new product strategies of the two main competitors in the commercial aircraft industry. The development of the A380 aircraft was selected to determine to what extent the companies had a choice in setting their product development strategies. The conclusion is that neither has the alleged freedom for setting its strategy. Implications of this finding are that the strategy theory needs to be adjusted for this choice issue, and that management should not always be held fully responsible for the developing events.  相似文献

Editorial     
This paper presents an overview of issues for future research. as identified by the papers appearing in the Special Issue on Innovation in Telecommunications. To this end. we elaborate upon the emergence of a new innovation regime in telecommunications, discuss the performance and sustainability of this new innovation regime, and reflect upon institutional choices for the regime and accompanying policy options. Further research on innovation in telecommunications is advocated, taking up a broad range of issues, including long-term industrial evolution and sustainability concerns in a wide sense.  相似文献
