Working artefacts: ethnomethods of the prototype

This paper follows recent science studies in theorizing information technologies as socio-material configurations, aligned into more and less durable forms. The study of how new technologies emerge shifts, on this view, from a focus on invention to an interest in ongoing practices of assembly, demonstration, and performance. This view is developed in relation to the case of the 'prototype', an exploratory technology designed to effect alignment between the multiple interests and working practices of technology research and development, and sites of technologies-in-use. In so far as it is successful, the prototype works as an exemplary artefact that is at once intelligibly familiar to the actors involved, and recognizably new.     

THE THERAPEUTIC ALLIANCE IN HOME‐BASED FAMILY THERAPY: IS IT PREDICTIVE OF OUTCOME?

This study examined the association between the therapeutic alliance in family therapy and changes in symptom distress, interpersonal relationships, and family coping. The participants (N = 81) were members of low socioeconomic status families referred to a university clinic for in-home family therapy. Participants completed the Outcome Questionnaire, Family Crisis Oriented Personal Evaluation, and the Family Therapy Alliance questionnaires. Regression analyses revealed that the therapeutic alliance explained 19% of the variance in symptom distress changes for mother, 55% for fathers, and 39% for adolescents. The implications of these findings for practicing and researching family therapy are presented.     

An Empirical Test of the Relative Validity of Expert and Lay Judgments of Risk

This article investigates how accurately experts (underwriters) and lay persons (university students) judge the risks posed by life-threatening events Only one prior study (Slovic, Fischhoff, & Lichtenstein, 1985) has previously investigated the veracity of expert versus lay judgments of the magnitude of risk. In that study, a heterogeneous grouping of 15 experts was found to judge, using marginal estimations, a variety of risks as closer to the true annual frequencies of death than convenience samples of the lay population. In this study, we use a larger, homogenous sample of experts performing an ecologically valid task. We also ask our respondents to assess frequencies and relative frequencies directly, rather than ask for a "risk" estimate--a response mode subject to possible qualitative attributions-as was done in the Slovic et al. study. Although we find that the experts outperformed lay persons on a number of measures, the differences are small, and both groups showed similar global biases in terms of: (1) overestimating the likelihood of dying from a condition (marginal probability) and of dying from a condition given that it happens to you (conditional probability), and (2) underestimating the ratios of marginal and conditional likelihoods between pairs of potentially lethal events. In spite of these scaling problems, both groups showed quite good performance in ordering the lethal events in terms of marginal and conditional likelihoods. We discuss the nature of expertise using a framework developed by Bolger and Wright (1994), and consider whether the commonsense assumption of the superiority of expert risk assessors in making magnitude judgments of risk is, in fact, sensible.     

Preaching to the converted: conversion language and the constitution of the TV evangelical community

A paradox is noted in the presentation of conversion in TV evangelism; this is that although the necessity of being converted is a common theme it is clear that the evangelists are aware that their audience is already converted. An attempt is made to resolve the paradox by showing how TV evangelists use conversion language as rhetoric to legitimate their role and the rationality of the organisation which they represent. It is further shown how this legitimation is itself made possible through another use of conversion language which creates a sense of moral community embracing evangelists, organisation and audience as copartners in the shared project of conversion. Finally, it is shown how the presentation of TV evangelism as the central ritual of a moral community generates a further conversion rhetoric which depicts the community as both exclusive of and yet open to non-members; a contradiction which is resolved through the establishment of distinctive roles within the community related to the activity of winning converts.     

New balanced sampling plans excluding adjacent units

Hedayat et al. [1988a. Sampling plans excluding contiguous units. J. Statist. Plann. Inference 19, 159–170; 1988b. Designs in survey sampling avoiding contiguous units. In: Krishnaiah, P.R., Rao, C.R. (Eds.). Handbook of Statistics, vol. 6. Elsevier, Amsterdam, pp. 575–583] first introduced balanced sampling designs for the exclusion of contiguous units. Sampling plans that excluded the selection of contiguous units within a given sample, while maintaining a constant second-order inclusion probability for non-contiguous units, were investigated for finite populations of N units arranged in a circular, one-dimensional ordering. There remain many open questions about the existence of such plans and their extension to plans excluding adjacent units. We present new generation techniques and new balanced sampling plans for the exclusion of adjacent units under finite, one-dimensional, circularly and linearly ordered populations.     

Disability and identity: the challenge of epilepsy

Through examining the case of people with epilepsy (which, as we demonstrate, has an ambiguous status in relation to both popular and academic conceptions of disability) we explore the fluid, negotiable and contingent nature of identity and, in particular, the identification as ‘disabled’. Disability, we argue, cannot be reduced to either biology or social oppression, or even primarily to biological or social factors: it is the outcome of a complex interaction between a multiplicity of factors – biological, environmental, social, psychological, cultural and political – which will interact and be experienced differently by different people, at different times and in different situations. Rather than conceiving of disability in ‘all or nothing’ terms and of differing explanations as competing and mutually exclusive, it would be more productive to see them as partial and potentially complementary contributions to the better understanding of a complex and multifarious reality.     

BUYING THEIR VOTES? A STUDY OF LOCAL TAX‐PRICE DISCRIMINATION

A population's demographic composition may affect political support for various public services. This article examines whether the aging‐in‐place of local residents decreases financial support for public schools in the United States. I expand on previous empirical work by examining whether tax‐price reductions offered to elderly homeowners moderate their effect on local school revenues. The results reveal that an aging population structure substantially decreases school revenues, unless elderly homeowners receive state‐financed reductions in their local tax‐prices. Sizable differences hold even when comparing school districts located near each other but on opposite sides of state borders. Given the imminent aging of the population structure in the United States and many other developed countries, governments' targeted tax reduction policies could have important effects on equilibrium school revenues.

The logic of preference reconsidered

Preferences are an important object of study in economic theory. Their logico-mathematical study has become prominent with the raise of modern decision theory and with the new conceptions of utility-functions and personalistic probabilities. The ‘basic logic’ at the foundation of the more advanced theories of preference, however, has been relatively little investigated. The pioneer work is Hallden's The Logic of ‘Better’ of the year 1957, followed by von Wright's The Logic of Preference in 1963. The topic has turned out unexpectedly problematic and there is as yet little consensus among logicians about the basic laws of preferring. A reason for this is apparently that there exist several concepts of preference which must be disentangled and kept apart in a logical theory. How this is to be done is discussed in the introductory sections (1–5) of the present paper. In Section 8 is sketched a logic for an asymmetric and connected preference-relation which holds between ‘possible worlds’ within a subject's ‘preference-horizon’ (Section 7). Preferences between states of affairs generally are called holistic when they hold ceteris paribus, i.e., when there is a corresponding preference-relation between any pairs of possible worlds which differ only in those two states and in no others. (Section 6.) Holistic preferences between states are asymmetrical and transitive but they do not form a linear preference order. (Section 9.) Failure to notice this, the author maintains, is responsible for much confusion in the traditional treatment of the subject. In the concluding sections (10–12) the author discusses the mutual relations of the value-absolutes, the good and the bad. Can they be defined in the terms of the relative notion of betterness or preference (and logical constants) alone? The definition which says that the goodness of a state is the holistic preference of it over its contradictory, answers the question affirmatively but conflicts with several deep-rooted axiological intuitions of ours. A more satisfying definition of the value-absolutes requires the additional notion of a value-less state (world) with which all the other states may be compared. In this connection some ideas of G. E. Moore about the notion of an ‘empty’ world can be interestingly exploited.     

Old and Cold: Older People and Policies Failing to Address Fuel Poverty

Research, funded by the British Gas Help the Aged Partnership and carried out by the Institute of Gerontology, King's College London, explored the multidimensional issues of fuel poverty. A sample of older homeowners and private renters living in England, Scotland and Wales were interviewed in the Spring of 2003 to explore their experiences of keeping their homes warm in the preceding winter. It was found that almost half of the sample for whom full information was available were in fuel poverty. Government schemes failed to address some important issues. Grants were only available to those with “passport benefits”, excluding those who had minimal occupational pensions. Although most respondents had central heating, it was often old and ineffective, yet grants were not available to modernize them. Government schemes did not extend to paying for external and internal insulation for solid wall properties yet many older people live in such property. Several older people lived in rural areas not connected to mains gas. As mains gas currently provides the cheapest fuel, they faced high bills, yet government policies do not address the differential fuel costs in these areas. The culture of many older people in the study contributed to their living in cold homes. They lived frugally and usually turned heating off in daylight hours during winter. It was also a common practice to sleep in an unheated bedroom during winter and to keep the window open at night. Such practices are acknowledged to be unhealthy.
