Markov Chains and De-initializing Processes

We define a notion of de-initializing Markov chains. We prove that to analyse convergence of Markov chains to stationarity, it suffices to analyse convergence of a de-initializing chain. Applications are given to Markov chain Monte Carlo algorithms and to convergence diagnostics.     

The parameters of prejudice: knowledge of ethics and age bias

This study examined two matters pertinent to social work practice: professional ethics and age bias among practicing social workers. Because social work ethics demand competent practice within one's area of proficiency, and because bias toward any segment of social work clientele impedes competent practice, prejudicial attitudes toward older people are problematic. This study found that age bias exists among practicing social workers (N = 367), with no discernible association between knowledge of professional ethical standards and age bias. The findings suggest a subtle and pervasive bias associated with work with older people. Positive bias was more prevalent than negative bias.

‘We've Got One of Those’: The Peripheral Status of Women in Male Dominated Industries

This article uses evidence from 269 interviews in five companies to consider whether (i) equal opportunity laws, policies and practices, (ii) more women gaining post-entry professional qualifications, establishing themselves on the lower rungs of hitherto male careers, and working full-time, combined with (iii) projected skill shortages, are likely to break down gender segmentation and lead to greater equality in employment during the 1990s. The evidence suggests that even females who start strongly and appear potential high-fliers are still being obstructed by harsh, in some respects, and in other ways patronizing, workplace cultures, coupled with demands for career commitment that are incompatible with the domestic responsibilities which it is assumed women will adopt, and which the majority are in fact still adopting at least at certain stages during their working lives. The effects in the companies studied were to deflect women out of mainstream careers into peripheral occupations, or into peripheral jobs within skilled mainstream occupations. In these companies neither the men nor the exceptional women who were succeeding appeared a likely source of pressure for change, and male domination remained fully compatible with the firms' preferred skill formation strategies.     

The Single Assessment Process in Primary Care: Older People's Accounts of the Process

Recent government policies have been active in addressing socialinclusion and active participation of older people in many aspectsof societal life. Independence and well-being animate thesedevelopments and are evident in the emphasis on person-centredservices within the single assessment process for older people(Department of Health, 2002b). Drawing on a feasibility study of the Single Assessment Processas a ‘case-finding’ approach, this paper presentsfindings drawn from older people’s accounts of this experience.These accounts indicate the potential of the process for identifying‘low-level’ need, whilst raising issues of accessto formal services and resource constraint; also they underlinethe importance of understanding how older people seek ways ofmanaging their own health and well-being, whilst continuingto contribute to the social cohesion of society by providingsupport to their peers and to younger generations. Interdependence, it is suggested, rather than dependence shouldunderlie any approach to assessing older people’s needs,if we are to appreciate and build upon the complexity of olderpeople’s strategies for actively managing their lives.     

Worker perceptions of procedural justice in workers’ compensation claims: Do unions make a difference?

The differences between union and nonunion workers’ perceptions of the fairness of the workers’ compensation claims process are examined. The hypothesis tested is that union members should perceive this process as more fair due to union “voice.” The data were collected in a survey of injured workers in Michigan who had filed a workers’ compensation claim. The empirical results indicate that unions have little impact on the perceived fairness of the claims process and that the main contribution of unions is the provision of a complaint mechanism. From the Bill of Rights to Chief Justice Earl Warren’s recurring inquiry of counsel, “but is it fair?” fair treatment has been treated as a value enforceable by law, standing at the very core of the constitutional, political, and social rights of the individual. —Westin and Feliu (1988, p. 255)     

The evaluation ranking scale: clarification of methodological and procedural issues

Compared with CSQ-8, a typical questionnaire approach to assessing global patient satisfaction, the Evaluation Ranking Scale (ERS) had equally good patient acceptability, yielded more normally distributed satisfaction scores, and results allowed comparative information about patients' evaluation of specific service dimensions. The study also addressed key questions that have emerged about the ERS procedure. Patients apparently do not distinguish conceptually between "importance" of dimensions and "satisfaction" with dimensions in the first phase (ranking) of the ERS. Results did confirm that the ERS sequence of ranking and then rating the dimensions is essential to achieving optimal utility of results. The ranking task seems to have an organizing effect on patients' approach to the rating task. This effect does not work to dictate results in the rating phase but rather seems to familiarize patients with the dimensions to be rated thereby yielding greater potential discriminative capacity for the ERS. Finally, results indicate that the ERS can be administered in a flexible fashion that yields additional information about the absolute importance of the six dimensions without loss of desired operating characteristics for the measure.     

Official conceptualizations of person-centered care: Which person counts?

Numerous studies have indicated that a “psycho-social” person-centered care approach, involving the delivery of a compassionate, respectful model of care, leads to a high quality of life, particularly for older people living in residential care. This has prompted policy-makers to endorse this approach. Yet, some commentators have argued that the model of person-centered care in official government policies equates to a “consumer-based” rather than a psycho-social approach, as it focuses solely on offering service-users more choice and on promoting independence. However, as such arguments are made in the absence of any empirical analysis, it is unclear both whether such a distinction exists in practice, and, if so, how this alternative model developed. This study explores the development of minimum standards for residential care settings for older people in Ireland in order to address this gap in our understanding of person-centered care. Findings confirm that a consumer-driven model of person-centered care underpins the Irish Standards; residential care is portrayed as a hotel-like service and residents as discerning consumers, which may be unsuitable for older people in residential care with limited capacity to make key choices. Analysis indicates that this model can be seen both as an extension of consumer-driven policies endorsed by many neo-liberal governments, and also of policy-makers' fears of losing their autonomy when they reach the “Fourth Age”. This study is particularly illuminating, given the similarities between the Irish care system with England, Scotland, Wales, Northern Ireland and Australia.     

The Cognitive Domain of the Quality of Life of University Students: A Re-Analyses of an Instrument

This paper presents the re-analysis of a previouslypublished instrument, based on Bloom's taxonomy,developed to measure the cognitive domain of thequality of life of university students. The items inthis instrument were assessed using Guttman's SmallestSpace Analysis. The findings generally supportBloom's conceptualization, identifying 5 of 6dimensions in the taxonomy: Knowledge, Comprehension,Application, Analysis, and Evaluation. The findingsprovide support for the enduring utility of Bloom'staxonomy, and reinforce the ongoing need to testtheoretically informed instruments using sophisticatedstatistical techniques.
