Discount-neutral utility models for denumerable time streams

This paper formulates and axiomatizes utility models for denumerable time streams that make no commitment in regard to discounting future outcomes. The models address decision under certainty and decision under risk. Independence assumptions in both contexts lead to additive or multiplicative utilities over time periods that allow unambiguous comparisons of the relative importance of different periods. The models accommodate all patterns of future valuation. This discount-neutral feature is attained by restricting preference comparisons to outcome streams or probability distributions on outcome streams that differ in at most a finite number of periods.     

Career Counseling in a Volatile Job Market: Tiedeman's Perspective Revisited

This article explores implications of Tiedeman's original theory for career counselors. Some components of the theory seem to be compatible with existing volatile job market conditions. Notions of career path recycling, development in reverse, nonlinear progress, and parallel streams in career development are explored. Suggestions are made for counseling interventions and future research using this perspective.     

‘Just teach us the skills please,we'll do the rest’: empowering ten‐year‐olds as active researchers

This paper discusses the outcomes of an initiative to empower ten‐year‐olds as active researchers. It debates some of the barriers that are commonly cited with regard to children of this age taking ownership of their own research agendas—power relations, competence, knowledge and skills—and challenges the status quo. It describes a study in which a group of ten‐year‐olds participated in a taught programme aimed at equipping them with the knowledge and skills to design their own research. This empowering process resulted in the children undertaking research projects of their own choosing, designed, carried out and reported entirely from their perspective. Reports from two of those projects are presented as part of this paper.     

Coming out at work: performativity and the recognition and renegotiation of identity

This paper is about ‘coming out’ and the process of disclosure and non‐disclosure of minority sexual identity in organizations. The process of ‘coming out’ is important for the individual lesbian or gay man since it is concerned with the discursive recognition and renegotiation of their identity. The study uses storytelling and a double narrative approach, where 92 individuals were interviewed to produce 15 stories of coming out, which were used for discussion in focus groups. The research took place within 6 organizations – 2 emergency services, the police and the fire service, 2 civil service departments and 2 banks. A conceptual framework is developed to explain the process of disclosure, showing it to be a continuing process rather than a single event. The concept of performativity is used to explain how in coming out the discursive practice and the telling of sexuality performs the act of coming out, making it an illocutionary speech act, and one which is made as an active or forced choice. The performative and perlocutionary speech acts interact with available subject positions thereby impacting on the individual's subjectivity. Sexuality is an under‐researched area of diversity in work organizations, as well as being one of the most difficult to research, so the level of access afforded by this research and the framework it produces provides a significant contribution to our understanding of minority sexual identity at work.     

Examining the link between program implementation and behavior outcomes in the lifestyle education for activity program (LEAP)

Lifestyle Education for Activity Program (LEAP) was a comprehensive, school-based intervention designed to promote physical activity in high school girls. The intervention focused on changes in instructional practices and the school environment to affect personal, social, and environmental factors related to physical activity. Multiple process evaluation tools and an organizational assessment tool were developed to monitor program implementation from a framework called the LEAP essential elements, which characterized complete and acceptable intervention delivery; secular trends were also monitored. Using process data, LEAP intervention schools were categorized into low- and high-implementing groups and compared with control schools on nine essential elements assessed at the organizational level. The Wilcoxon scores test revealed that low- and high-implementing intervention, and control schools differed significantly on two of nine administrator-reported organizational-level components: having a physical activity team and having a faculty-staff health promotion program. A mixed-model analysis of covariance indicated that, compared to control schools, a greater percentage of girls in high-implementing schools reported engaging in vigorous physical activity. Process evaluation can be used to understand the relationship between level of implementation and successful program outcome.     

An improved comorbidity summary score for measuring disease burden and predicting mortality with applications to two national cohorts

Abstract

Research involving administrative healthcare data to study patient outcomes requires the investigator to account for the patient’s disease burden in order to reduce the potential for biased results. Here we develop a comorbidity summary score based on variable importance measures derived from several statistical and machine learning methods and show it has superior predictive performance to the Elixhauser and Charlson indices when used to predict 1-year, 5-year, and 10-year mortality. We used two large Veterans Administration cohorts to develop and validate the summary score and compared predictive performance using the area under ROC curve (AUC) and the Brier score.
