THE DOGIT ORDERED GENERALIZED EXTREME VALUE MODEL

This paper introduces the Dogit ordered generalized extreme value (DOGEV) model, for handling discrete variables that are ordered and heterogeneous. In particular, the DOGEV model can be applied to questionnaire responses on questions allowing a discrete set of ordered possible responses, where there is a preference for particular responses and possibly multiple modes in the data. The DOGEV model combines a model for choice set generation with the ordered generalized extreme value model. The paper illustrates the model using two empirical examples: a model of inflationary expectations and a model for students' evaluations of teaching.     

Bayesian methods for analysing ringing data

A major recent development in statistics has been the use of fast computational methods of Markov chain Monte Carlo. These procedures allow Bayesian methods to be used in quite complex modelling situations. In this paper, we shall use a range of real data examples involving lapwings, shags, teal, dippers, and herring gulls, to illustrate the power and range of Bayesian techniques. The topics include: prior sensitivity; the use of reversible-jump MCMC for constructing model probabilities and comparing models, with particular reference to models with random effects; model-averaging; and the construction of Bayesian measures of goodness-of-fit. Throughout, there will be discussion of the practical aspects of the work - for instance explaining when and when not to use the BUGS package.     

Family therapist comfort with and willingness to discuss client sexuality

Limited empirical information exists on whether or not marriage and family therapists are having sexuality-related discussions with their clients. When helping professionals ignore client sexuality, the potential for unintended negative outcomes increases. The researchers surveyed 175 clinical members of the American Association for Marriage and Family Therapy to assess how their clinical training and education, their perceived sexual knowledge, and their comfort with sexual material influenced their willingness to engage in sexuality-related discussions with their clients. The results indicate that sexuality education and supervision experiences are the cornerstone for a therapist's base level of comfort. It is through sexuality education and supervision that sex knowledge is acquired and comfort levels are increased. Once comfort with sexual discussions increases, then therapists are more likely to engage in sexuality discussions with their clients.     

A Bayesian Approach to Integrated Ecological and Human Health Risk Assessment for the South River,Virginia Mercury‐Contaminated Site

We conducted a regional‐scale integrated ecological and human health risk assessment by applying the relative risk model with Bayesian networks (BN‐RRM) to a case study of the South River, Virginia mercury‐contaminated site. Risk to four ecological services of the South River (human health, water quality, recreation, and the recreational fishery) was evaluated using a multiple stressor–multiple endpoint approach. These four ecological services were selected as endpoints based on stakeholder feedback and prioritized management goals for the river. The BN‐RRM approach allowed for the calculation of relative risk to 14 biotic, human health, recreation, and water quality endpoints from chemical and ecological stressors in five risk regions of the South River. Results indicated that water quality and the recreational fishery were the ecological services at highest risk in the South River. Human health risk for users of the South River was low relative to the risk to other endpoints. Risk to recreation in the South River was moderate with little spatial variability among the five risk regions. Sensitivity and uncertainty analysis identified stressors and other parameters that influence risk for each endpoint in each risk region. This research demonstrates a probabilistic approach to integrated ecological and human health risk assessment that considers the effects of chemical and ecological stressors across the landscape.     

Is the Gene-Environment Interaction Paradigm Relevant to Genome-Wide Studies? The Case of Education and Body Mass Index

This study uses data from the Framingham Heart Study to examine the relevance of the gene-environment interaction paradigm for genome-wide association studies (GWAS). We use completed college education as our environmental measure and estimate the interactive effect of genotype and education on body mass index (BMI) using 260,402 single-nucleotide polymorphisms (SNPs). Our results highlight the sensitivity of parameter estimates obtained from GWAS models and the difficulty of framing genome-wide results using the existing gene-environment interaction typology. We argue that SNP-environment interactions across the human genome are not likely to provide consistent evidence regarding genetic influences on health that differ by environment. Nevertheless, genome-wide data contain rich information about individual respondents, and we demonstrate the utility of this type of data. We highlight the fact that GWAS is just one use of genome-wide data, and we encourage demographers to develop methods that incorporate this vast amount of information from respondents into their analyses.     

Black,Queer, and Looking for a Job: An Exploratory Study of Career Decision Making Among Self-Identified Sexual Minorities at an Urban Historically Black College/University

This thematically analyzed study seeks to explore the career decision perceptions of sexual minority college students at an urban historically black college/university (HBCU). This qualitative focus group study delved into how sexual minorities feel their visible variables of race, gender expression, and degree of disclosure influence their career thought process. Theories relative to the study included Krumboltz’s social learning theory of career decision-making, gender role theory, racial socialization, Cass’s homosexual identity model, and impression management. Though participants initially proclaimed they did not allow their sexual minority identity to affect their career decisions, their overall responses indicated otherwise.     

Hiding Customer Complaints: Studying the Motivations and Forms of Service Employees' Complaint Concealment Behaviours

This study aims to explore both how and why customer service employees conceal the complaints made by customers. Using an exploratory qualitative approach, data were gathered through the in‐depth interviewing of 25 managers, 25 supervisors and 57 front‐line employees of UK general retailers/supermarkets. Data analysis reveals that the concealment of customer complaints by store employees of all hierarchical levels is common. Front‐line, customer‐contact employees were found to conceal complaints in four ways: through (1) misleading customers, (2) complaint resolution without logging, (3) concealing recorded complaints and (4) falsification of recorded complaints. Store‐level supervisory and managerial employees were also found to conceal complaints in four ways: through (1) complaint resolution without logging, (2) concealing recorded complaints, (3) the non‐recording of complaints and (4) the disregarding of ‘minor’ complaints. The motives for complaint concealment differed between managerial/supervisory and front‐line employees but included reasons of (1) personal protection, (2) perceived customer unpleasantness, (3) serial complaint avoidance, (4) alienation, (5) friends or family protection, (6) instrumental gain, (7) avoidance of additional work, (8) perceived unfairness and (9) limited time. These findings suggest that theorists and practitioners need to acknowledge the existence and prevalence of these motives and behaviours and incorporate them into their conceptualizations and practices.     

Strategic Experimentation

This paper extends the classic two-armed bandit problem to a many-agent setting in which N players each face the same experimentation problem. The main change from the single-agent problem is that an agent can now learn from the current experimentation of other agents. Information is therefore a public good, and a free-rider problem in experimentation naturally arises. More interestingly, the prospect of future experimentation by others encourages agents to increase current experimentation, in order to bring forward the time at which the extra information generated by such experimentation becomes available. The paper provides an analysis of the set of stationary Markov equilibria in terms of the free-rider effect and the encouragement effect.
