Efficient Classification-Based Relabeling in Mixture Models

Effective component relabeling in Bayesian analyses of mixture models is critical to the routine use of mixtures in classification with analysis based on Markov chain Monte Carlo methods. The classification-based relabeling approach here is computationally attractive and statistically effective, and scales well with sample size and number of mixture components concordant with enabling routine analyses of increasingly large data sets. Building on the best of existing methods, practical relabeling aims to match data:component classification indicators in MCMC iterates with those of a defined reference mixture distribution. The method performs as well as or better than existing methods in small dimensional problems, while being practically superior in problems with larger data sets as the approach is scalable. We describe examples and computational benchmarks, and provide supporting code with efficient computational implementation of the algorithm that will be of use to others in practical applications of mixture models.     

New methodologies for the 2001 Census in England and Wales

This paper looks at the significant innovations that are being introduced into the 2001 Census in England and Wales. Whilst the traditional concept of collecting information from each person and household in the country at a fixed point is being adhered to, in virtually every other respect the Census in 2001 will be very different from those that have preceded it.     

Integrating post-qualification study into the workplace: The candidates' experience

The PQ framework for qualified social workers has struggled to become consistently established within workplace training and practice organisations across the UK. This is likely to become a focus for change as the Government reviews current structures and attempts to 'modernise the workforce' by encouraging the creation of cultures of post-qualification learning and continuing professional development [PQ/CPD]. This paper argues that the current emphasis upon the rhetoric of 'performance management' needs to be balanced by attention to the realities of integrating operational and professional development demands within socio-cultural contexts. This paper reports and discusses the results of a questionnaire survey into the experiences of registered PQ candidates within a Local Authority SSD. A summary of key results is provided. The discussion identifies a number of themes and strategies for integrating PQ into the workplace. These are based upon a range of attitudinal and practical factors, such as decision-making; supervision; study arrangements; mentoring; and motivation, that cover some of the experiences of candidates. The paper concludes by drawing parallels with similar developments within nursing and recommends that all stakeholders involved in PQ development need to help establish the conditions within practice contexts where social workers can link service and policy initiatives with the requirements for post-qualification study.     

Evaluation of a Seven State Criminal History Screening Pilot Program for Long-Term Care Workers

This article summarizes results from an evaluation of a federally sponsored criminal history screening (CHS) pilot program to improve screening for workers in long-term care settings. The evaluation addressed eight key issues specified through enabling legislation, including efficiency, costs, and outcomes of screening procedures. Of the 204,339 completed screenings, 3.7% were disqualified due to criminal history, and 18.8% were withdrawn prior to completion for reasons that may include relevant criminal history. Lessons learned from the pilot program experiences may inform a new national background check demonstration program.     

Spinoza in the history of cultural psychology and activity theory

ABSTRACT

This review of the place of Spinoza in the history of cultural-historical activity theory begins with a synopsis of Ilyenkov’s influential essay “Spinoza—Thought as an Attribute of Substance” and adds further points. I go on to look at the historical context of Spinoza’s work, the mixed character of his legacy, and the need to see Spinoza as one moment in an entire historical development.     

Associations Among Attachment Style,Burnout, and Compassion Fatigue in Health and Human Service Workers: A Systematic Review

Health and human service workers are at risk for developing burnout or compassion fatigue due to the demanding nature of their work. Attachment theory makes specific predictions that may help explain why some workers experience burnout or compassion fatigue and others do not. The purpose of this systematic review is to identify and attempt to explain patterns and inconsistencies in results across studies that have examined the association between adult attachment style and burnout or compassion fatigue. Ten studies representing a diverse range of disciplines within the health and human service sectors were included in the research synthesis. The findings demonstrated consistent results for secure and anxious attachment, suggesting that attachment security is associated with lower levels of burnout, whereas attachment anxiety is associated with higher levels of burnout. Some studies found an association between avoidant attachment and burnout, whereas others did not. The results are discussed in terms of their implications for the selection, training, and supervision of health and human service workers.     

How to Win “Spend” and Influence Partners: Lessons in Behavioral Operations from the Outsourcing Game

The Outsourcing Game is a role‐play simulation that has been deployed in industry and academic training courses worldwide. It incorporates the concepts of hidden actions, hidden information, and misaligned incentives, and conveys messages about power, trust, and reputation. The game depicts the adventures of Acme, the brand owner of a product manufactured by an outsourced supply chain. Through a series of negotiations, Acme attempts to influence its partners (two suppliers and two service providers) by distributing its procurement “spend.” These partners, in turn, sway each other via side payments. To simulate the non‐linear shifts in power that occur as outsourcing increases, we represent decision‐making by a voting scheme with uneven vote allocations. This paper analyzes a database of game results to reveal behavioral factors that can undermine conspicuous win–win process improvements. For instance, preferences can be sensitive to the sequence in which the alternatives are encountered; decision‐makers might value not only their own rewards, but also fairness in the allocation of total gains; and effectiveness of negotiation tactics will vary with community norms of acceptable behavior. Along the way we extend the political economics literature about power in block‐based voting by proposing a heuristic approach for incorporating voter preferences.
