A minimally informative likelihood for decision analysis: Illustration and robustness

The authors discuss a class of likelihood functions involving weak assumptions on data generating mechanisms. These likelihoods may be appropriate when it is difficult to propose models for the data. The properties of these likelihoods are given and it is shown how they can be computed numerically by use of the Blahut-Arimoto algorithm. The authors then show how these likelihoods can give useful inferences using a data set for which no plausible physical model is apparent. The plausibility of the inferences is enhanced by the extensive robustness analysis these likelihoods permit.     

Paradoxes, locations and the need for social coherence: a qualitative study of living with a learning difficulty

Policy rhetoric over recent decades has promoted social inclusion of the more vulnerable sectors of society, such as people with learning difficulties. This study aimed to describe the experiences of people who live with learning difficulties in order to inform local service development. Thirty-five people with a learning difficulty and/or a family member were interviewed. A model of social coherence was developed that moves beyond the self-limiting debates about social inclusion and exclusion. It is underpinned by a sense of location for the person with a disability in relation to services and carers, family and community, dependency and risk, temporality and space, events, control and society. Key recommendations are for services to know the individual and his/her family; to be responsive to individual needs; to enhance the capacity of families and communities to support people with difficulty in learning; and to help these people to feel more valued.     

Executive Information Systems: Recent Developments and Research Imperatives

SUMMARY The reluctance of top managers to use computers themselves has become almost legendary, although there are good reasons for their apparent preference for traditional information sources and access routes. Isolated cases have shown how computer-based executive support systems can be used by top managers when great care is taken by the system developers over data presentation and the user interface. Now, the advent of high quality commercial software means that Executive Information Systems (EIS) may become far more widespread. This paper describes the principal features of the new EIS from the executive users' point of view and indicates those characteristics which appear to be most conducive to success. Research directions which will identify the extent and impact of EIS software on top management are identified.     

Power mobility and the built environment: the experiences of older Canadians

In this article, we employ data from qualitative interviews with 15 men and 14 women aged 51–92 to examine older Canadian adults’ experiences of utilizing power wheelchairs and motorized scooters in the context of the built environment. When functioning properly and utilized within accessible spaces, power mobility devices provided many of the participants with the autonomy they desired. However, the features and functionality of power mobility equipment also constrained participants’ abilities to negotiate their surroundings and maintain valued social roles and physical activities. Participants’ experiences of power mobility technology as enabling or disabling were further complicated by the organization of the built environment, as the men and women described encountering various barriers to mobility within both public and private spaces. We discuss our findings in relation to the extant literature concerning the social and spatial construction of disability.     

The Role of Mothers' Communication in Promoting Motivation for Math and Science Course‐Taking in High School

In the context of concerns about American youths' failure to take advanced math and science (MS) courses in high school, we examined mothers' communication with their adolescent about taking MS courses. At ninth grade, U.S. mothers (n = 130) were interviewed about their responses to hypothetical questions from their adolescent about the usefulness of algebra, geometry, calculus, biology, chemistry, and physics. Responses were coded for elaboration and making personal connections to the adolescent. The number of science, technology, engineering, and mathematics courses taken in 12th grade was obtained from school records. Mothers' use of personal connections predicted adolescents' MS interest and utility value, as well as actual MS course‐taking. Parents can play an important role in motivating their adolescent to take MS courses.     

The spaces and ethics of organic food

Initial assessments of the potential for organic food systems have offered an optimistic interpretation of the progressive political and ethical characteristics involved. This positive gloss has prompted a stream of critique emphasising the need to explore the ambiguities and disconnections inherent therein. In this paper, we consider the case of Riverford Organic Vegetables,¹ arguably the largest supplier of organic vegetables in the UK, and suggest that existing debates assume too much about the “goods” and “rights” of organic food and leave important questions about the spaces and ethics of organic food. We argue that, in the case of Riverford, the space of organic food production and distribution is neither the small, local, counter-cultural farm nor the large, transnational, corporate firm. Rather, simultaneously, the spaces of organic food production and distribution are the national network, the regional distribution system and the local farm. In addition, in the case of Riverford, the ethics of organic food exhibit few grand designs (of environmental sustainability, for example). Rather, the ethics of organic food are best characterised as: ordinary, since they relate to concerns about taste, value for money, care within the family and so on; diverse, since multiple practices steer the production and distribution of organic food; and graspable, in that both vegetables and box have material and symbolic presence for consumers.
