Nonparametric estimation of welfare changes

In this article, I propose a simple nonparametric method of estimating welfare measures with no structural assumptions on the demand system. The method is illustrated for both the single good and the multiple good case, using simulated data. Standard errors of the welfare changes are derived using standard bootstrap techniques. The compensating variation and deadweight loss resulting from a housing price increase is evaluated using Canadian mortgage data. The GAUSS coding, which is very short, is included.     

Disaffected Loyalties in a Changing Contractual Environment

In this paper we examine the effects of the changing employee-employer relationship on loyalty – a construct we developed along Hirschman’s model. The impact on perceptions of loyalty during a downsizing is assessed using a design that manipulates HRM policies toward the use of temporary employees, retraining, employee voice, seniority and community coordination. We introduce ideological orientation as a variable that will have direct and indirect affects. Both MBA students and managers (N = 269) participated in the study. All HRM policies and ideological orientations have direct affects; in addition some indirect effects for ideological orientation emerged. This revised version was published online in July 2006 with corrections to the Cover Date.     

Correlating Post-disaster Support Network Density with Reciprocal Support Relation Satisfaction: An Elderly Cohort Within One Year of the 2011 Japan Disasters

While there has been much empirical investigation into how social support networks improve mental health in post-disaster communities, network density—the extent members within a network are acquainted—remains under-researched. This study examines correlations between support network density and support reciprocity satisfaction in an elderly sample (N = 221), and the influence on post-disaster depression and trauma symptomology in a fishing community south of the Fukushima nuclear plant within 1 year of the March 11, 2011 Japan earthquake. The Brief Inventory of Social Support Exchange Network (BISSEN) taps support network density, support source by relational category, tangible and emotional type, and providing or receiving direction of social support. Density measurement convergent validity was established from questionnaire responses. After confirming network density construct and criteria validity, and extracting components reciprocal support relationship satisfaction, correlation between these two variables was moderate at r = 0.34. However, reciprocity satisfaction moderately explained mental health variance, but results were not significant for density nor interaction between predictors. These results question the assumption that support network density and support reciprocity can be validly incorporated into a construct of “social capital” necessarily promoting mental health.     

Confidence and the effectiveness of creative methods in qualitative interviews with adults

ABSTRACT

This paper examines two contrasting creative methods; a drawing task and a LEGO building task used in a study exploring the gap between policy and practice in widening participation to higher education across two different types of university in England. These creative methods were used within 16 semi-structured interviews in seven universities to attempt to explore deeper understandings of everyday policy and what they mean in practice and to make comparisons across types of institutions. This paper examines the role that creative confidence played in the effectiveness of both methods through exploring the successes and failures of each arguing that understanding these barriers can improve the successful use of these methods, especially with adults. When these barriers are overcome, the paper also demonstrates how creative methods encouraged more reflective discussion of everyday issues, increased levels of rapport, and shared engagement in the interview process.     

Competing Failure Risk Analysis Using Evidence Theory

Safety systems are important components of high-consequence systems that are intended to prevent the unintended operation of the system and thus the potentially significant negative consequences that could result from such an operation. This presentation investigates and illustrates formal procedures for assessing the uncertainty in the probability that a safety system will fail to operate as intended in an accident environment. Probability theory and evidence theory are introduced as possible mathematical structures for the representation of the epistemic uncertainty associated with the performance of safety systems, and a representation of this type is illustrated with a hypothetical safety system involving one weak link and one strong link that is exposed to a high temperature fire environment. Topics considered include (1) the nature of diffuse uncertainty information involving a system and its environment, (2) the conversion of diffuse uncertainty information into the mathematical structures associated with probability theory and evidence theory, and (3) the propagation of these uncertainty structures through a model for a safety system to obtain representations in the context of probability theory and evidence theory of the uncertainty in the probability that the safety system will fail to operate as intended. The results suggest that evidence theory provides a potentially valuable representational tool for the display of the implications of significant epistemic uncertainty in inputs to complex analyses.     

The relationship between marriage and family therapists and complementary and alternative medicine approaches: a national survey

Respondents to a mail survey of a random sample (N = 424) of Clinical Members of the American Association for Marriage and Family Therapy provided information about their contexts of practice, use of complementary and alternative medicine (CAM), and relationships with CAM providers. Consistent with both national trends and the experience of psychologists as reported in a similar survey, the results of this survey suggest that marriage and family therapists have been affected significantly by and have a growing awareness of CAM practices. Limitations of the study and implications for the field are discussed.     

DO EMPLOYERS PAY FOR CONSISTENT PERFORMANCE?: EVIDENCE FROM THE NBA

In a world of uncertainty in which a worker's performance is variable over time and average performance is unknown when hiring, how will employers determine compensation? We develop a monitoring and signaling model where information is symmetric and parties are risk neutral. Monitoring costs increase with inconsistency, lowering pay for inconsistent workers. If discrimination exists, minority workers will be rewarded less than majority workers for improving consistency. Testing these and other predictions using National Basketball Association data, we find that consistent professional basketball players are paid more, but, in contrast to previous studies, there is no evidence of discrimination.
