Cyberculture, cyborg post-modernism and the sociology of virtual reality technologies : Surfing the soul in the information age

The relation between humans and machines has come to assume a central place within the social sciences, particularly in debates about the role of science and about information technologies. Cyberculture plays a key role in these debates, drawing its inspiration in large part from virtual reality systems. This article examines the affinities between two aspects of cyberculture: cyborg post-modernism, which revolves around the notion that the boundaries between humans and machines are becoming irretrievably blurred, and the cyberpunk movement within youth culture with its futuristic ideas about information and communication machines. While cyberculture may be far ahead of the current state of the technology, it is argued here that its new conception of the relation between politics, technology and art is an important reflection of changes within the cultural industries that surround information and communication technologies within advanced societies.     

Discriminating between wealth and information effects in event studies in accounting and finance research

This article examines the power of tests of given size to detect and distinguish between wealth (i.e., mean) and information (i.e., variance) effects in event studies. We find that an Estimated Generalized Least Squares (EGLS) mean-effects test is consistently more powerful than the test based upon the average standardized residual and is as powerful as a nonparametric rank test. Unlike the test based upon the average standardized residual and the rank test, the EGLS test is well specified even when the event affects the variances of the prediction errors. We also find that conventional parametric tests to detect changes in the variance of the event-day average abnormal return are misspecified when the null of no change is true. We analyze the reasons this occurs and suggest a rank procedure that produces tests of the correct size under the null. Our evidence suggests that the critical factors allowing researchers to distinguish between wealth and information effects are an estimation procedure incorporating the heteroskedasticity inherent in market model prediction errors and an explicit test for event-day variance changes.     

The determinants of EST adoption by manufacturing plants in developing countries

This article reports on the findings of a survey undertaken in late 2001-early 2002 on the determinants of environmentally sound technology (EST) adoption by 98 plants in eight developing countries. We review the literature on technology diffusion and technology capabilities as well as empirical studies with an exclusive focus on developing countries that explicitly addressed environmental performance or EST adoption to formulate our heuristic model that guided our investigation. We examine in some detail the determinants of both prevention and abatement technologies, which has seldom been investigated, in developing countries.In full recognition of literature that cites a host of reasons that cause plants to adopt EST we take into account both contextual and plant-specific factors. We use an ordered choice model that revealed that plant-specific factors assume a pre-dominant role in explaining the adoption of higher order of complexity EST. Plant-specific factors, specifically environmental commitment, technological capabilities, and ownership, and market factors, specifically foreign involvement and water and energy price perception, matter in determining the type of technological response and thus in explaining the adoption of higher-order complexity EST. Two governmental factors, regulatory implementation strategy and international donor assistance, also play a role in the adoption of EST. However, civil society, in particular community pressure that has been identified as an important determinant of environmental performance, does not play a role because of the way the dependent variable is constructed to capture higher orders of technological complexity.     

Workplace Union Resilience in the Merseyside Fire Brigade

Here the author provides evidence from empirical case study research into the changing nature of workplace industrial relations and trade union organisation within the Merseyside Fire Brigade over the last 10–15 years. He documents the main processes of development within an historical context assessing workplace unionism during the 1980s, the recent challenge posed by managerial restructuring in the early 1990s, and the wider implications for debates about the ‘state’ of workplace unionism in Britain today.     

Business and Human Rights in South Africa: An Analysis of Antecedents of Human Rights Due Diligence

The purpose of the present article is to analyse South African listed companies’ public reporting in order to contribute to our understanding of how and why companies consider human rights. The empirical analysis is placed in the context of the increasing prominence of human rights as a business issue, premised in part on the activities of the United Nations (UN) Special Representative of the Secretary General (SRSG) on human rights and business. On the basis of a content analysis of the public reports of the top 100 companies listed on the Johannesburg Stock Exchange (JSE), we test hypotheses focused on the antecedents of companies’ demonstrated human rights due diligence, with particular reference to assumptions or findings of the SRSG and institutional theory. Some of our results are unexpected: there is little influence exerted by the sector and size of companies in our sample, and there is also an unexpectedly insignificant impact of company participation in the UN Global Compact and the JSE Socially Responsible Investment Index. On the other hand, a key predictor of human rights due diligence is an explicit leadership commitment, and important roles are also played by government regulations and stock exchange listing rules.     

Presidential Address: Antitrust restrictions on single-firm strategies

Abstract This article offers an overview of selected developments in the law and economics of antitrust regulation of single‐firm strategies. The strategy generating the most cases historically is resale price maintenance. Here, the law has moved sharply in both Canada and the U.S. towards more solid economic foundations. Yet a gap between the law and economics remains. The economics of resale price maintenance is reviewed within a framework that is much simpler and more general than the existing literature. The law on a second strategy, predatory pricing, represents in my view a success story for the influence of economic theory in spite of the absence of a single accepted theory of predatory pricing. The remaining single‐firm strategies are concerned largely with the exclusion by a dominant firm of rivals from a market. I review, with application to cases, the two most basic questions concerning exclusionary strategies. Are exclusionary, anticompetitive contracts ever entered into voluntarily by market participants? On the other hand, is complete or substantial foreclosure of a market through exclusionary strategies necessarily anticompetitive?     

A multivariate innovations state space Beveridge–Nelson decomposition

The Beveridge–Nelson vector innovations structural time series framework is a new formulation that decomposes a set of variables into their permanent and transitory components. The proposed framework is flexible, modelling inter-series relationships and common features in a simple manner. In particular, it is shown that this new specification is simpler than conventional state space and cointegration approaches. The approach is illustrated using a trivariate data set comprising the GDP of Australia, the USA and the UK.
