网络能力前因研究——以中国制造业为例

世界已然变成了由节点构成的网络,企业无法独立于其他企业而孤立地存在,而是相互联结并嵌入于商业网络之中,网络是企业价值创造的最终来源。而攫取这种网络价值的源于企业在商业网络关系中获取、整合和重构内外竞争力来维持竞争优势的能力,即网络能力。前因研究主要是通过理论分析和实证研究来识别影响网络能力形成和发展的主要因素。根据已有相关研究所探索的结果,可以归纳为四个主要因素:内部资源配置,文化开放度,企业家要素和网络活动经验。通过实证研究,探寻它们对网络能力构建的影响机制。

The clash of managerial and professional logics in public procurement: Implications for innovation in the health-care sector

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.     

The bones of the body politic: thoughts on the Savorgnan de Brazza Mausoleum

This essay examines three examples of political treatment of the dead (specifically their bones) in the Republic of the Congo: the return of the remains of its capital's founder, Savorgnan de Brazza; the disappearance of the body of André Matswa, hailed by the people as their messianic ‘saviour’ guardian; and finally, the treatment of unidentified victims of the various armed conflicts that occurred during the years 1990–2002. These events can be analysed through the prism of two different historical perspectives: in terms of the moyenne durée, the treatment of Matswa's bones paved the way for the subsequent occurrences by creating a precedent; in the context of the ‘present of history’, the construction of a Brazza mausoleum is contemporaneous with official denial of the presence of human remains scattered across the capital city of Brazzaville as a result of armed conflicts. The comparative analysis of these historical configurations posits a set of circumstances whereby the bones become a symbolic buttress of the capital. The historical puzzle here is to understand how that which came together in claiming Matswa's bones becomes, in the context of democratization of the regime, an aesthetic sense of the ‘beauty of death’ as expressed by people when they see the shrine as their country's finest architectural accomplishment. Through the splendour of the monument, this aesthetic sense articulates the denial of the presence of the nameless dead.

基于熵技术的农村公路施工质量综合评价

鉴于农村公路施工质量评价所存在的模糊性和随机性的特点,在建立涵盖整个施工质量影响因素为一级指标的施工质量综合评价指标体系的基础上,运用模糊数学理论,建立了二级模糊综合评价模型,借用熵的概念计算客观权重的方法,提出了施工质量模糊综合评价的方法。应用该方法对某农村公路项目质量进行评价,得出其评价结果为"良好"。最后,对该方法进行了定量解算,从而提高了施工质量评价的客观性和科学性,通过对结果的深入分析,可找出施工过程中存在的不足之处,从而为目标明确、有的放矢的改进施工质量提供理论依据,具有一定的实用价值。     

Swedish tribalism and Tanzanian entrepreneurship: preconditions for trust formation

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.

Urban Informality and the State: Geographical Translations and Conceptual Alliances

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.
