The aim of this paper is to explore the relationship between entrepreneurship and the structure of the periphery. The objective is to reach an understanding of the entrepreneurial process within the context of the periphery, which is traditionally seen as a poor environment. The paper considers the concept of peripherality and identifies a process of gravitation that drains higher order services towards the core. However, this deterministic model does not correspond with the realities of the Scottish Highlands. The paradox is that new businesses are being created that appear to use old redundant peripheral values such as tradition. It is argued that it is the social construction of the periphery that produces this post-modern change. The qualitative methodology indicates the emergence of a new spatial paradigm of aesthetic consumption. Two indicative case studies are presented which show that entrepreneurship is the creation and extraction of value from the environment. Their businesses are the commodification of non-material and aesthetic values. Further analysis of these data demonstrates that entrepreneurs interpret their own version of the environment, rather than merely reacting to it. In turn, they enact this interpretation which forms the basis of their businesses. 相似文献

Understandings of informality commonly derive from research undertaken in states perceived as lacking the capacity to regulate the practices of their populations. This Interventions forum aims to expand the geographical parameters of empirical research on urban informality. A more global approach, we argue, also necessitates questioning assumptions that undergird this concept—in particular the underlying conception of the state. In this vein, this collection of papers aims to rethink theories of the state through the lens of informality, and vice versa, to inform and refine the concept of informality through a more thorough understanding of states. In so doing, the contributions engage with concepts that have been central both to theories of the state and to the study of informality, namely governance, agency, legitimacy, sovereignty and legality. Following this introduction setting out our theoretical approach, the Interventions forum unites five empirical studies that discuss the nexus of informality and states in contexts that have been researched less extensively from this perspective, each tackling one of the above‐mentioned concepts. Based on these different entry points, the papers provide novel angles on a state‐theoretical understanding of informality. A concluding essay brings these approaches together, reflecting on the possibilities of translating concepts to different sites. 相似文献

Although entrepreneurship seems to offer a universal economic solution, there are some doubts about whether it is universally attractive. We argue that entrepreneurship is a socially constructed concept and consequently the meanings, and hence the appeal, of the enterprise will vary internationally. We argue that how entrepreneurship is understood affects how attractive it seems. Accordingly, we investigated the meanings of entrepreneurship by analysing a range of metaphors of entrepreneurship gathered from schools across Europe. We found that both the meaning and understandings of the practices vary considerably. For most, the concept of entrepreneurship as an engine of the economy is attractive, but for some, the practices of entrepreneurs were considerably less appealing. We find links between national socio-economic contexts and attractiveness. We argue that culture and context seem to influence the social constructions of entrepreneurship and hence the attractiveness of entrepreneurial options. We also find that the pedagogical national narratives of the entrepreneur stand in dynamic tension with the performative national processes of entrepreneurship. 相似文献

This article explores cultural cityism at a time when a more expansive, ‘planetary’ urbanization is argued to have superseded ‘the city’ as the dominant urban form. It takes an essentially Lefebvrian problematic and works this through an examination of one aspect of contemporary metropolitan culture, the L.S. Lowry exhibition at Tate Britain, held in the summer of 2013. The article scrutinizes the juxtaposition of Lowry's images of the industrial city with the image of ‘global’, corporate London provided by Tate Britain itself. The exhibition is presented as evidence of Lefebvre's argument that although the urban core has imploded and exploded, through images the city ‘can perpetuate itself, survive its conditions’. Taking stock also of the preponderance of city images in culture more widely, it is argued such images make a fetish of the city, producing also an ‘urban pastoral’ that obscures the defining characteristics of urban life today. Finally, Benjamin's concept of the ‘dialectical image’ and Rancière's notion of the ‘sentence image’ are invoked to capture the flashing together of past and present city images and the opportunities for critical reflection this constellation presents. 相似文献

This essay on Shenzhen, China, presents three vignettes addressing the question of home in a city of migrants. The first section explores the ubiquitous narratives of success forming the city's foundational myth. The second follows this myth into the world of a Shenzhen filmmaker and his characters, as they navigate the tension between the idea of home and the urge to start anew, resulting in the suspended possibility of the title. The last section looks at young architects who hope to preserve the city's heterotopic sites of migrants and original villagers through architectural innovations. The cases show how an economy of desire supplements the political economy of this export-driven city. The city appears as an urban desiring machine that produces itself as an object of desire for the migrants of all classes who flock to its factories, "urban villages", white-collar jobs, luxury villas and underground economy. The essay is an encounter with the mythology of success and failure, the intertwining of home as an end and home as the beginning, and with the manipulation of space that allows residents to control their own subjectivity. 相似文献

This article addresses the enactment of public procurement and its influence on adoption and diffusion of innovation, using a case study of public procurement of a low-tech medical device innovation in Swedish healthcare. Based on interviews and documentation, the article illustrates the various perspectives of the different professions involved in the complex task of setting the requirement specification for the tender. The technology identities of the medical device (innovation) are constructed and negotiated by the actors: procurement administrators, health-care professionals and suppliers within the adoption space. Examining the enactment of the procurement process as part of the adoption space is a way to deepen our understanding of the social component within public procurement. 相似文献

Abstract. This article presents a survey of theories of monopoly capitalism. The defining characteristic of monopoly capitalism is that developed capitalist economies are seen as essentially dominated by firms which operate in oligopolistic industries. It discusses in chronological order the contributions of Hilferding, Lenin, Kalecki, Steindl, Baran and Sweezy, and Cowling to the monopoly capitalism approach. By drawing out some common features of the authors discussed we arrive at an implicit view of the nature of theories of monopoly capitalism. The macroeconomic aspects of monopoly capitalism are discussed with emphasis on the implications for the level of economic activity. A further section discusses the international aspects of the monopoly capital approach. The final section of the paper reviews criticisms of the theories of monopoly capitalism with concentration on those advanced from a Marxist perspective. 相似文献

This paper is concerned with the Bayesian estimation and comparison of flexible, high dimensional multivariate time series models with time varying correlations. The model proposed and considered here combines features of the classical factor model with that of the heavy tailed univariate stochastic volatility model. A unified analysis of the model, and its special cases, is developed that encompasses estimation, filtering and model choice. The centerpieces of the estimation algorithm (which relies on MCMC methods) are: (1) a reduced blocking scheme for sampling the free elements of the loading matrix and the factors and (2) a special method for sampling the parameters of the univariate SV process. The resulting algorithm is scalable in terms of series and factors and simulation-efficient. Methods for estimating the log-likelihood function and the filtered values of the time-varying volatilities and correlations are also provided. The performance and effectiveness of the inferential methods are extensively tested using simulated data where models up to 50 dimensions and 688 parameters are fit and studied. The performance of our model, in relation to various multivariate GARCH models, is also evaluated using a real data set of weekly returns on a set of 10 international stock indices. We consider the performance along two dimensions: the ability to correctly estimate the conditional covariance matrix of future returns and the unconditional and conditional coverage of the 5% and 1% value-at-risk (VaR) measures of four pre-defined portfolios. 相似文献
