A Consistent Method for Calibrating Contingent Value Survey Data

This paper outlines a statistical method for calibrating contingent value survey data derived from the assumption that individuals make constrained utility maximizing decisions. The method proposed allows us to determine the influence of respondent characteristics on bias, as distinct from their influence on the preference parameters. A specific functional form for individual preferences was used to derive closed-form analytical expressions for willingness-to-pay and willingness-to-accept that allow systematic deviations in individual responses to be explicitly modeled by providing a structural interpretation of the error term. Promising results are obtained for both open-ended and dichotomous choice data using three CV data sets.

Adaptation and change in Queensland’s rangelands: Cell grazing as an emerging ideology of pastoral-ecology

Does the current global political economic framework, or more specifically, the cost–price squeeze associated with primary production, restrict the choices of Australian cattle graziers in moving to more sustainable practices? It has often been argued by primary producers and academics, alike, that current terms of trade have resulted in reduced profitability at the property level, and as such, have made it difficult for landholders to shift to practices which are environmentally sustainable. Whilst there is mounting evidence that this is case, there is also evidence that some graziers have been able to adapt to the prevailing market conditions through an ideological as well as ‘practice’ shift. Findings from qualitative research in Central Queensland, Australia, has highlighted how ‘cell grazing’ departs from the traditional or conventional aspects of grazing which can be described as productivist, to an approach closely approximating Lang and Heasman’s (2004) ‘ecologically integrated paradigm’ [Lang, T., Heasman, M., 2004. Food Wars: The Global Battle for Mouths Minds and Markets. Earthscan, London]. It is argued that cell grazing is, at present, a marginal activity that requires an ideological and cultural shift, as well as an investment in new infrastructure, however, current cell grazing activities may also demonstrate that beef grazing has the potential to be both economically and environmentally sustainable.     

China’s Foreign Trade: Perspectives From the Past 150 Years

This paper studies the trade of China in the past 150 years, starting from the first opening of China after the Opium War. The main purpose of the paper is to identify what is (and was) China’s ‘normal’ level of foreign trade, and how these levels changed under different trade regimes, from 1840 to the present. We present new evidence on China’s foreign trade during the treaty port era (1842–1948), drawn from disaggregated trade data collected by the Chinese Maritime Customs Service, that yields important findings for current research. First, although the volume of foreign trade remained limited initially, there was a notable expansion in the diversity of products, with many new goods being imported into China. Second, the regional diffusion of foreign goods through China was greatly facilitated by the expansions of the port system. Third, the importance of Hong Kong as an intermediary in China’s trade has undergone long‐term fluctuations suggestive of learning effects. China’s recent wave of liberalization has led by the early 1990s to a trade level comparable to the high of the 1920s. While much of China’s recent growth in world trade is in line with her income growth, there is no doubt that China’s trade openness today, comparable by some measures to Denmark’s, is a stunning reversal relative to the pre‐1978 and also the pre‐1840 period. The paper emphasises the roles that history and institutional change have played in this.     

Assessing the needs of assisted reproductive technology users of an online bulletin board

Consumers who are infertile and decide to use assisted reproductive technologies undergo lengthy, expensive and potentially risky medical procedures in their quest for a pregnancy and a live birth. In this research we use a consumer model of decision making to analyse the process. We review information available to consumers and we assess use of an online bulletin board which gives consumers social support and medical information during the process. We conclude with the needs for consumer education and protection.     

Consumer education in the UK: new developments in policy,strategy and implementation

Consumer education is an integral part of the European Community's consumer policy. It plays a key role in consumer empowerment, helping consumers gain the skills, attitudes and knowledge they need to be able to gear the choices they make as consumers to their economic interests and to protect their health and safety. In its policy statement, the Directorate General for Health and Consumer Protection states that the European Community is aware that joint measures at national and Community levels should be more structured, in order to achieve maximum effectiveness. This paper aims to set out the current policy and strategic context for consumer education and empowerment in the UK; review the role of UK government bodies and other agencies concerned with developments; review recent literature; present the results of interviews with an extensive range of key stakeholders and the results of a survey of service heads for trading standards throughout the UK. It will consider implementation, partnership, resources, ideas and opportunities. The research found that the agenda for consumer education in the UK is at an interesting stage of development. The Enterprise Act 2002 gives the Office of Fair Trading (OFT) a statutory power to carry out educational activities. Consumer education is also moving up the agenda in the trading standards service. In addition, the teaching of citizenship in English schools is already stimulating new developments in consumer education. The paper will consider the need for organizations like these to work together to build on these policy developments and ensure that consumer education gains the profile it needs to influence consumer attitudes and behaviour.     

Differences between workstations and keypad group support systems: Implications for keypad GSS facilitators

Organizations are successfully using group support systems (GSS) to improve efficiency, effectiveness, and satisfaction in organizational meetings. Meeting success relies on making an appropriate match between group, taks, and technology. This responsibility often falls to the meeting facilitator. This article draws upon GSS and facilitation literature to develop a framework for the discussion of effective facilitation in workstation and keypad meeting environments. The article identifies differences between the systems and how they impact upon the behavior of the meeting facilitators and their choice of technology. Compensatory actions are proposed for keypad facilitators to address the lack of key workstation features. Keypad strengths are also identified to show the opportunities available to facilitators to maximize the benefits of using these GSS. Further, it is proposed that different types of GSS are not mutually exclusive and should be seen as complementary components of a suite of GSS tools designed to support organizational goals.     

Nutrition knowledge of caterers and constraints to offering more healthy meals

The study determined whether school and workplace caterers in the South East of England have the necessary knowledge to provide more healthy meals, and the constraints preventing them offering them. Results indicated that most caterers knew about current nutritional guidelines and sources of nutrients, and thus should be able to produce healthy meal choices. Most caterers believed that certain foods could be prepared successfully using alternative ingredients or cooking methods. The main constraints to offering more healthy options were taste, cost and what customers wanted. The main changes that had been made were the use of reduced-fat ingredients and cooking practices aimed at reducing the fat content of dishes.     

Evaluating the Productivity Performance of Agricultural Enterprises in Ireland using a Multiple Output Distance Function Approach

This paper uses a distance function approach to measure and decompose productivity growth of Irish agriculture between 1984 and 2000 for four principal farming systems. The technology used by each system is found to be sufficiently different as to warrant a system‐by‐system approach. The overall rate of productivity growth in Irish agriculture is found to be just over 1% for this period, but there are significant differences between systems. Sheep systems had the highest rate of productivity growth followed by dairy and tillage. Productivity in cattle farms fell during this period although there is evidence that this trend has been reversed in more recent years.
