ABSTRACT

This article analyses neo-colonial dynamics at peripheral units of a Western global professional service firm. Drawing on postcolonial theory, an empirical study at global news agency Reuters’ subsidiaries in Mumbai and Bangalore shows how socio-ideological and technocratic control mechanisms allow subsidiary workers to elevate their status, while still cementing their role as dominated in the global hierarchy and silencing any resistance. Thus, on the one hand, it might appear that the global service firm provides periphery units the opportunity to become equals of core units, representing a ‘nurturing’ role achieved by instilling aspirational values and shaping imaginations. On the other hand, coercive and universalising routines such as performance assessments highlight the ambivalent nature of global firm initiatives to incorporate the periphery on an equal footing with core units, demonstrating the countervailing nature of contemporary power relations.  相似文献

In the quest to model various phenomena, the foundational importance of parameter identifiability to sound statistical modeling may be less well appreciated than goodness of fit. Identifiability concerns the quality of objective information in data to facilitate estimation of a parameter, while nonidentifiability means there are parameters in a model about which the data provide little or no information. In purely empirical models where parsimonious good fit is the chief concern, nonidentifiability (or parameter redundancy) implies overparameterization of the model. In contrast, nonidentifiability implies underinformativeness of available data in mechanistically derived models where parameters are interpreted as having strong practical meaning. This study explores illustrative examples of structural nonidentifiability and its implications using mechanistically derived models (for repeated presence/absence analyses and dose–response of Escherichia coli O157:H7 and norovirus) drawn from quantitative microbial risk assessment. Following algebraic proof of nonidentifiability in these examples, profile likelihood analysis and Bayesian Markov Chain Monte Carlo with uniform priors are illustrated as tools to help detect model parameters that are not strongly identifiable. It is shown that identifiability should be considered during experimental design and ethics approval to ensure generated data can yield strong objective information about all mechanistic parameters of interest. When Bayesian methods are applied to a nonidentifiable model, the subjective prior effectively fabricates information about any parameters about which the data carry no objective information. Finally, structural nonidentifiability can lead to spurious models that fit data well but can yield severely flawed inferences and predictions when they are interpreted or used inappropriately.  相似文献

在数据包络分析中,大量的交叉效率模型已被提出。然而选择不同的目标模型将实现不一样的交叉效率评价。本文基于针对单个决策单元实施的对抗型和仁慈型两个交叉效率模型,用合作博弈方法来研究交叉效率模型的选取,并利用Shapley值对决策单元进行排序。最后通过实例分析显示该排序方法充分利用了最小交叉效率和最大交叉效率的信息完全排序了所有决策单元,具有一定的综合性和合理性。  相似文献

Porter and Kramer’s concept of creating shared value (CSV) has been welcomed as an approach to corporate social responsibility (CSR) among corporations that also provides a practical opportunity for dialogue in public relations, but it has been little examined from the general population’s (i.e., the public’s) perspective. Such scrutiny is important because its findings enable public relations to contribute to the debate and development of CSV from both the public’s and the organization’s viewpoints. Additionally, if public relations professionals understand how the public perceives CSV, they can give a strategic perspective to top management for maximizing moral capabilities of the business and formulate effective communication to promote CSV initiatives. This study investigates whether the public prefers corporations to practice CSV as opposed to intrinsic CSR as a separate pursuit from business interests. It also explores the role of leadership as an influential and ethical construct in implementing effective CSV as perceived by the public. The public’s preference for CSV over intrinsic CSR was revealed in a survey of 1784 participants in the United States (US), Germany, and China. Factor analysis results further suggested that effective CSV competencies of CEOs were construed as a unidimensional concept in the US, but German and Chinese participants viewed it as two-dimensional. The public perceived that leaders’ moral character played a more important, core role in effective CSV than did altruistic and behavioral attributes, across nations. Network analysis of the perceived effective CSV-characteristics provides further implications for CSV communication.  相似文献

Abstract

Risk and performance management are at the core of complex bespoke systems (CBSs). CBSs are developed to customer–specified requirements in terms of structure, functionality and conformance. This article examines how risk and performance management are integrated as essential systems in the successful development of projects across multi-organizational functions in complex bespoke system (CBS) organizations. The article argues for the development of a quality management system that consists of two sub-processes: quality control and quality development. Using three case studies from engineering companies, we provide evidence and insights of the way change control, quality development and quality performance are developed in innovating business solutions.  相似文献

Abstract

One of the most important factors in building and changing communication mechanisms in social networks is considering features of the members of social networks. Most of the existing methods in network monitoring don’t consider effects of features in network formation mechanisms and others don’t lead to reliable results when the features abound or when there are correlations among them. In this article, we combined two methods principal component analysis (PCA) and likelihood method to monitor the underlying network model when the features of individuals abound and when some of them have high correlations with each other.  相似文献

筝源于瑟,说法有三:一、"筝,小瑟也";二、"颂瑟,筝也";三、分瑟为筝.其说起因不外两个方面:一、筝与瑟的形制相似;二、瑟之弦数(多谓"二十五弦",亦有谓"二十七弦"者)或为十二弦和十三弦两种筝的弦数之和,或可分出两张十三弦筝.筝源于瑟说虽非空穴来风,但其根据汉代之后筝与瑟的形制以及二者弦数的某种巧合而作的推断,仅仅是关于筝发展演进中的形制的变化,从未真正触及到早期的"五弦筑身"或"鼓弦竹身"之筝的源起问题.  相似文献

商洛客家方言古入声今读的情况是塞音韵尾已全部丢失,入声韵尾脱落后,古入声韵或以主要元音相近为原则,归入相应的阴声韵,或独立成韵,相对比较复杂。入声调的今读情况各地也存在差异,罗湾保留阴入、阳入,安乐只有阴入,其他地方没有入声调,清入字或归上声或归阳入,全浊字都归去声,次浊入字部分随清入字走,部分随全浊入字走。  相似文献
