This essay explores organizations in civil society as constituting an important sphere of social action in which alternative geopolitical worldviews are produced and disseminated beyond the state. The authors discuss the conceptual relationship between non-governmental organizations and the geopolitics pursued by states and also develop an appropriate methodological program to investigate organizational geopolitics. This is accomplished by employing critical discourse analysis methods in the examination of press releases made by notable civil society organizations in response to the events of 11 September. While most organizational responses condemned the attacks and expressed a shared sense of sympathy for the victims, there was considerable divergence in the preferred geopolitical and social response – ranging from restraint and tolerance to aggressive militarism. The findings suggest organizations are not only important sites of alternative geopolitical representations beyond the state, but may also serve to reproduce and re-circulate dominant statecentered geopolitical visions as well.  相似文献

In this paper we review the path integral technique which has wide applications in statistical physics and relate it to the backward recursion technique which is widely used for the evaluation of derivative securities. We formulate the pricing of equity options, both European and American, using the path integral framework. Discretising in the time variable and using expansions in Fourier–Hermite series for the continuous representation of the underlying asset price, we show how these options can be evaluated in the path integral framework. For American options, the solution technique facilitates the accurate determination of the early exercise boundary as part of the solution. Additionally, the continuous representation of the state variable allows the relatively accurate and efficient evaluation of the option prices and the delta hedge ratio.  相似文献

We study the trend and the author name-ordering rule in finance publication using the publication records of 21 core finance journals during the period from 1990 to 2004. We empirically model the underlying factors that affect the alphabetical ordering rule among multi-authored finance articles. We find that the choice of alphabetical ordering is based on the quality of the article, institutional heterogeneity, team size and cultural factors. The central argument rests upon the need to signal and the importance of signalling within the context of bargaining behaviour among coauthors. The probability of choosing alphabetical name ordering rule is associated with high article quality, higher ranked institutions, smaller research team and the presence of European authors.  相似文献

The question of whether private firms should contract out for products and services or provide them internally (i.e. become more vertically integrated) has been a topic that has concerned scholars for many years. This article argues that the transaction costs in local contracting choices are linked to the characteristics of political systems that influence political and administrative uncertainty. Our analysis examines the transaction costs that result from executive turnover. Specifically, we are concerned with how uncertainty resulting from turnover in leadership positions in city government affects the ability of a municipality to negotiate contracts, make credible commitments to suppliers and faithfully uphold and enforce contracts once they are in force. We find that manager turnover reduces the likelihood of contracting with private sector providers. Mayor turnover has the opposite effect increasing contracting with both government and for-profit providers.  相似文献

Building on suggestions from the work of Martin Heidegger, a distinction is made between two ways of being in the world. One is associated with the unplanned particularity and care of Dasein, another with the planning and thinking-out of design; the former is characteristic of a more traditional way of life, the latter of contemporary life. Included are brief etymologies of `Dasein' and `design', along with some reflections on the two-fold history of design of internal structure and surface appearance (that is, of engineering and aesthetic design, respectively). The conclusion sketches out a problematics of engineering design as involving a disengagement from fundamental human experience, and suggests the need to discriminate between authenticity and inauthenticity in the world of design.  相似文献

This paper documents an investigation of drum-buffer-rope (DBR) scheduling and flow control methodology in single-product serial production lines. In particular, DBR flow control is reviewed and the importance of correctly representing this type of flow control mechanism in serial lines is discussed. Departures from valid DBR conceptual and simulation modeling are illustrated. It is shown that the model of a previously published paper is a push system not a DBR system, and that related conclusions regarding protective capacity and constraint location are unsupported. Correct modeling of DBR flow control is shown using discrete simulation experiments that compare the DBR model and a similar push model. Suggestions for additional research are offered.  相似文献

In this study, we evaluate the preference of consumers in Niger for different tuwo or couscous characteristics using a random utility‐based choice experiment, ordered probit analysis, and tree‐based partitioning. Data were collected through a structured survey administered at four sites. Preferences are estimated for three products (couscous, fermented tuwo, and nonfermented tuwo) made from five pearl millet cutivars. We provide relative valuation for different traits by type of product. Results show that product taste, color, and textural attributes are important, especially for tuwo and couscous. Probit and partitioning results show that taste and color are the first attributes that consumers use to distinguish more preferred millet food products from less preferred millet food products. This should provide some direction for millet breeding programs and food processing of millet.  相似文献
