Kurtosis and spread

An increase in kurtosis is achieved through the location- and scale-free movement of probability mass from the “shoulders” of a distribution into its centre and tails. We introduce a coherent structure of ordering and measures, requiring no symmetry assumption, that represent different formalizations of this movement. For this purpose spread functions and spread-spread plots are defined. The orderings impose growth patterns on the spread-spread plot of the distributions involved, and the weakest involve both a specific scale-matching technique and placement of “shoulders”. The role of existing kurtosis orderings and measures in this general context is identified and examples discussed throughout.     

Turning a blind eye: racial oppression and the unintended consequences of white ‘non-racism’*

The paper is based upon ethnographic research undertaken in a large metropolitan Careers Service in England. A consideration of differences between the intent and the outcome of action leads to an exploration of the ways in which white people come to understandings of their superordinate position relative to black people. By emphasising the concept of the materiality of ideology, the analysis attempts to go beyond a functionalist model which would regard a state apparatus as meeting the‘requirements’of capital in an unmediated and direct way. It is argued that racist ideology, as a specific set of linked but contradictory ideas, must inhere unevenly within the structures of everyday life and that struggles against racism have to take into account the discriminatory nature and importance of white‘non-racism’     

Validation of a Multi‐Dimensional Measure of Strategy Development Processes

In this paper, we present evidence on the measurement properties of an instrument that assesses six dimensions of organizational strategy development. These dimensions are labelled planning, incrementalism, cultural, political, command and enforced choice. Using data from 5332 managers, results indicate the instrument has acceptable reliability and validity. Exploratory factor analysis confirms its underlying structure. Generally, the sub‐scales have acceptable internal reliability and inter‐rater reliability at the organizational level (n = 770 organizations). Further, using data aggregated at the organizational level, the sub‐scales are judged to have acceptable validity from the pattern of correlations amongst the six dimensions and with other variables.     

An Empirical Approach to Sufficient Similarity: Combining Exposure Data and Mixtures Toxicology Data

When assessing risks posed by environmental chemical mixtures, whole mixture approaches are preferred to component approaches. When toxicological data on whole mixtures as they occur in the environment are not available, Environmental Protection Agency guidance states that toxicity data from a mixture considered “sufficiently similar” to the environmental mixture can serve as a surrogate. We propose a novel method to examine whether mixtures are sufficiently similar, when exposure data and mixture toxicity study data from at least one representative mixture are available. We define sufficient similarity using equivalence testing methodology comparing the distance between benchmark dose estimates for mixtures in both data‐rich and data‐poor cases. We construct a “similar mixtures risk indicator”(SMRI) (analogous to the hazard index) on sufficiently similar mixtures linking exposure data with mixtures toxicology data. The methods are illustrated using pyrethroid mixtures occurrence data collected in child care centers (CCC) and dose‐response data examining acute neurobehavioral effects of pyrethroid mixtures in rats. Our method shows that the mixtures from 90% of the CCCs were sufficiently similar to the dose‐response study mixture. Using exposure estimates for a hypothetical child, the 95th percentile of the (weighted) SMRI for these sufficiently similar mixtures was 0.20 (i.e., where SMRI <1, less concern; >1, more concern).     

Enabling SMEs to take full advantage of e-business

Electronic business is rapidly changing the relationships between supply chain partners. This paper looks at what is needed to allow SMEs to participate fully in supply chain integration. First, current trends in supply chain integration, electronic commerce, and Internet support are examined. Next, the goals and results of a study are presented which addressed SME needs in fast moving consumer goods supply chains. These concepts are then integrated to determine a way forward for SMEs to participate in e-business. It is found that current Virtual Markets (web-sites or on-line communities that facilitate finding a buyer or seller and track orders) address some customer - supplier relationships but need many enhancements before they can support fully integrated supply chains.     

对中国消费者非转基因菜油支付意愿的研究

有关中国消费者关于转基因食品接受度的资料非常有限.本文则首次尝试对中国消费者关于非转基因(non-GM)食用油的支付意愿(WTP)问题进行评估.通过对北京的671个消费者进行调查采访,运用假设评价方法(contingent valuation),可推导出消费者对非转基因菜油的支付意愿.为避免调查者无响应引起的偏差,运用了双变量概率选择模式对调查数据进行分析.研究结果表明,消费者对非转基因菜油的支付意愿受到了许多因素的影响,比如价格、风险意识、受教育程度和知识水平等等.计算所得的WTP显示,平均而言,被调查者愿意支付33%的额外费用来消费非转基因菜油.这一结果表明,中国消费者对转基因油持有相当怀疑的态度.     

Exploring the Impact of Social Axioms on Firm Reputation: A Stakeholder Perspective

This study proposes a model of how deeply held beliefs, known as ‘social axioms, moderate the interaction between reputation, its causes and consequences with stakeholders. It contributes to the stakeholder relational field of reputation theory by explaining why the same organizational stimuli lead to different individual stakeholder responses. The study provides a shift in reputation research from organizational‐level stimuli as the root causes of stakeholder responses to exploring the interaction between individual beliefs and organizational stimuli in determining reputational consequences. Building on a conceptual model that incorporates product/service quality and social responsibility as key reputational dimensions, the authors test empirically for moderating influences, in the form of social axioms, between reputation‐related antecedents and consequences, using component‐based structural equation modelling (n = 204). In several model paths, significant differences are found between responses of individuals identified as either high or low on social cynicism, fate control and religiosity. The results suggest that stakeholder responses to reputation‐related stimuli can be systematically predicted as a function of the interactions between the deeply held beliefs of individuals and these stimuli. The authors offer recommendations on how strategic reputation management can be approached within and across stakeholder groups at a time when firms grapple with effective management of diverse stakeholder expectations.     

UNIONS, PLANTS, JOBS, AND WORKERS

The relationship between unions and their members is an important, yet neglected, subject in recent studies of the sociology of work. This study develops and tests a theory of union satisfaction and participation that combines recent research in the sociology of work with previous explanations of union satisfaction and participation provided by industrial relations researchers, in an attempt to understand the relationship between unions, plants, jobs, and workers in U.S. manufacturing industries. This theory predicts that union members will be satisfied with their unions and participate more in them if there are extensive ties between workers, employers, and unions. These ties stem from the focus of labor/management relations in particular, and class struggles in general, on market outcomes and the historical linkage of union membership with employment in the United States. The theory also predicts that unions them-selves act as ties to specific work settings and that union participation is a forum for voicing dissatisfaction with specific characteristics of workers' jobs. Testing these predictions is complicated by contradictory nature of the structure and organization of work in advanced industrial societies. The analysis provides qualified support for this theory, with data drawn from more unions, plants, and union members than have been used to date. In addition to discussing modifications to the theory and analysis presented here, the study includes a discussion of its implications for the future of unionization and the organization of work, in light of declines in union membership, increased efforts to decertify unions and resist union organizing efforts, and deindustrialization in the United States.
