Sick building syndrome and perceived indoor environmental quality: A survey of apartment buildings in Hong Kong

The outbreak of a highly communicable disease, SARS, in Asia in 2003 has revealed the health risk of living in a high-density environment. To show the important connection between human health and environmental quality, this study surveys the prevalence of sick building syndrome (SBS) among apartment residents and their evaluation of indoor environmental quality (IEQ). Based on a sample of 748 households living in Hong Kong, two interesting findings are revealed: (1) nasal discomfort was the commonest home-related SBS symptom despite the absence of any central ventilation system in apartment buildings; (2) noise, rather than ventilation, was the major IEQ problem perceived by residents. Our statistical analysis further showed that residents with SBS symptoms were less satisfied with their IEQ than those without. That is, despite a positive evaluation of specific IEQ criteria with respect to the building residents lived in, if they reported feeling SBS related symptoms, the overall IEQ evaluation of their building could still be negative. This perception bias gives rise to a sample selection problem in measuring perceived IEQ, which has implications on housing management practices and the formulation of a healthy housing policy.     

Participation, Authority, and Distributive Equity in East Timorese Development

The anthropology of development seeks to understand the complex encounter between international and national development regimes and local patterns of livelihood and being. As science and development move objects, at once material and discursive, through the networks of the social to reach “impoverished” others, local groups reach out to development actors to evaluate and appropriate their resources and accept or redirect those efforts. In a political interplay of disciplinary measures and localizing translations, development projects are re-invented, or aspects thereof refused, just as development actors strain to keep projects on track. With input from science and technology studies, this article explores the participatory, authoritative, and distributive dimensions to agricultural development in East Timor. Across four cases studies—a dairy, a greenhouse, a seed development program, and a permanent farming initiative—the politics of projects are compared and discussed within the broader context of colonial and postcolonial development. The article is based on a total of 1 year of fieldwork conducted in 2003, 2008, and 2009.     

The Development of Gaze Following in a Third‐Party Context

Infants follow the gaze of an individual with whom they are directly interacting by the end of the first year. By 18 months infants are capable of learning novel words in observational (or third‐party) contexts (Floor & Akhtar, 2006). To examine third‐party gaze following in 12‐ and 18‐month‐olds, the parent and experimenter engaged in a conversation while the infant was present. For 8 trials approximately every 30 sec the experimenter would turn her head to the right or left to fixate on a toy placed on either side of the room with the parent following suit. In the first experiment, the parent was seated next to the infant and the experimenter opposite, whereas in the second experiment the positions of the adults were switched. In Experiment 1, 18‐month‐olds but not 12‐month‐olds followed gaze. In Experiment 2, 12‐month‐olds acquired a tendency to follow gaze during the experimental session. These results suggest that an incipient ability to follow third‐party gaze is present by 12 months and that infants acquire a more reliable and general ability to follow the gaze of noninteractive others between 12 and 18 months.     

Culture,the 'sick role' and the consumption of health

This paper revisits Parsons's conception of the 'sick role' and examines the relevance of his writings on the cultural understanding of sickness to the consumption of health in the contemporary era. In terms of current developments, I focus on the development of pro-active approaches towards the healthy body, and the growth of 'information rich' consumers of health care. These have become prominent themes in sociology, and while Parsons's writings are usually viewed as anachronistic I argue they remain highly pertinent to understanding the emergence of informed, body conscious lay people. If Parsons's analysis of health is more relevant to current circumstances than many critics assume, however, it is not unproblematic. The residual categories associated with the sick role obscure the continued utility of his work on the general cultural values informing health care. It is Parsons's analysis of these values, I suggest, that needs rescuing from restricted understandings of the sick role and highlighting as an important resource for contemporary theorists.     

Business patterns within telecommunications

The global telecommunications changed from a number of co-operating national monopolies offering a restricted range of services to a competitive, growing market with players of many types and sizes, offering a large range of services. How can vertically integrated incumbents align themselves and their systems to best compete in this environment? Business patterns and enterprise modelling offer a tool to model a large organization as a number of smaller enterprises that can compete with and co-operate with smaller specialist players in the market. In order to identify enterprises, this paper proposes that there are only a limited number of types of enterprise (manufacturer, service supplier, reseller, that these enterprise types can only interact in a limited number of ways (component supply, aggregation supply, resell supply, trading, end-supply and commission). With the use of examples, this paper illustrates these types of enterprise and enterprise relationships, and how they can be combined to build both internal and external supply chains, and discusses some of the conclusions that can be drawn from this analysis.     

Managing Technology for Competitive Advantage : Editors

This article addresses the performance of the three largest Australian airports following their privatization. The airports represent cases of divestment of government business enterprises into privately-owned businesses each with differing ownership arrangements. The performances of the privatized airports are considered using financial data obtained from general purpose financial reports of the entities. There are significant implications for future divestment policies, including the value of divestment as a policy response in uncompetitive environments, the use of particular infrastructure investment models, and the nature of the linkage between ownership structure and financial performance.

Layered supervisory control architecture for reconfigurable automation

The development of control systems and supporting software remains one of the greatest obstacles to the widespread implementation of highly adaptive reconfigurable automation technology. This paper will present the structure of a modular automation control system designed to support rapid reconfiguration and redeployment of automation components. The paper will first present the concept of a layered system architecture and the use of modular automation components to support the construction of a wide variety of automated systems. This layered system architecture is then applied to the proposed modular supervisory control system responsible for configuring and driving automated production resources. Each of the control components comprising this modular control system will be presented.
