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.     

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.     

Peak performing organisations

The literature on organisational performance is riddled with measurement problems that cannot easily be solved. In contrast we argue that elite theory in terms of performance can be more easily measured by the win record of sports organisations. Accordingly, this article argues that certain organisational peak practices are key to understanding how peak performance is sustained. Through data collected from the top ten sports organisations in the world we introduce the embryonic theory of Peak Performing Organisations (PPO). Sustained PPO practices offer more robust outcomes than the genre of High Performing Organisations.     

Understanding the Adoption Process of National Security Technology: An Integration of Diffusion of Innovations and Volitional Behavior Theories

After the 9/11 terrorist attacks, the U.S. government initiated several national security technology adoption programs. The American public, however, has been skeptical about these initiatives and adoption of national security technologies has been mandated, rather than voluntary. We propose and test a voluntary behavioral intention formation model for the adoption of one type of new security technology: portable radiation detectors. Portable radiation detectors are an efficient way of detecting radiological and nuclear threats and could potentially prevent loss of life and damage to individuals’ health. However, their functioning requires that a critical mass of individuals use them on a daily basis. We combine the explanatory advantages of diffusion of innovation with the predictive power of two volitional behavior frameworks: the theory of reasoned action and the health belief model. A large sample survey (N = 1,482) investigated the influence of factors identified in previous diffusion of innovation research on portable radiation detector adoption intention. Results indicated that nonfinancial incentives, as opposed to financial incentives, should be emphasized in persuasive communications aimed at fostering adoption. The research provides a new integration of diffusion of innovation elements with determinants of volitional behavior from persuasion literature, and offers recommendations on effective communication about new security technologies to motivate public adoption and enhance national safety.     

Exploring variation in active network size: Constraints and ego characteristics

Studies of active personal networks have primarily focused on providing reliable estimates of the size of the network. In this study, we examine how compositional properties of the network and ego characteristics are related to variation in network size. There was a negative relationship between mean emotional closeness and network size, for both related and unrelated networks. Further, there was a distinct upper bound on total network size. These results suggest that there are constraints both on the absolute number of individuals that ego can maintain in the network, and also on the emotional intensity of the relationships that ego can maintain with those individuals.     

Working-Class Studies: Ongoing and New Directions

This paper gives an account of working-class studies as it has developed in the USA and UK. It includes a comparative assessment of ways in which the working-class and class analysis appear within academe. This argues that the different role played by social classes in the post-war settlement and its subsequent breakdown can account for divergent fortunes of class analysis in response to similar developments. The paper unpacks some of the opportunities and threats to further development of working-class studies in the UK. It is argued that the field needs to be developed in a way that is reflexively self-critical and avoids reproducing middle-class experience as universal. However, it notes the challenge of opening up space for the working class within the academy, particularly given the problem of the institutional embodiment of class together with the rigid framework of higher education in the UK.
