Exiting unemployment: How do program effects depend on individual coping strategies?

This paper analyses if individual coping strategies explain heterogeneous effects of participation in active labour market programs (ALMPs) on reemployment probabilities for the unemployed. I use survey data linked with administrative data from Statistics Denmark and focus on respondents who are unemployed or participating in ALMPs (n = 1310). To account for selection bias I analyse the data with a mixed logit model. I find that the coping strategies displayed by the unemployed persons explain heterogeneous effects of participation in ALMPs.     

Correcting the Errors: Volatility Forecast Evaluation Using High‐Frequency Data and Realized Volatilities

We develop general model‐free adjustment procedures for the calculation of unbiased volatility loss functions based on practically feasible realized volatility benchmarks. The procedures, which exploit recent nonparametric asymptotic distributional results, are both easy‐to‐implement and highly accurate in empirically realistic situations. We also illustrate that properly accounting for the measurement errors in the volatility forecast evaluations reported in the existing literature can result in markedly higher estimates for the true degree of return volatility predictability.     

Tissue Dosimetry, Pharmacokinetic Modeling, and Interspecies Scaling Factors

Interspecies scaling factors (ISFs) are numbers used to adjust the potency factor (for example, the q1* for carcinogens or reference doses for compounds eliciting other toxic endpoints) determined in experimental animals to account for expected differences in potency between test animals and people. ISFs have been developed for both cancer and non-cancer risk assessments in response to a common issue: toxicologists often determine adverse effects of chemicals in test animals and then they, or more commonly risk assessors and risk managers, have to draw inferences about what these observations mean for the human population. This perspective briefly reviews the development of ISFs and their applications in health risk assessments over the past 20 years, examining the impact of pharmacokinetic principles in altering current perceptions of the ISFs applied in these health risk assessments, and assessing future directions in applying both pharmacokinetic and pharmacodynamic principles for developing ISFs.     

Body Image for Women: Conceptualization, Assessment, and a Test of its Importance to Sexual Dysfunction and Medical Illness

The content and valence of women's body image attitudes, general and enduring positive or negative feelings about the body, are studied with psychometric analyses of measures and contrasted groups. Data from two frequently used measures (Body Image Scale, Derogatis & Melisaratos, 1979; Body Satisfaction Scale, Berscheid, Walster & Bohrnstedt, 1973) provided an evaluation of the construct and the assessment of body image. Two studies are provided. The construct analyses suggest two contents for body attitude measures: a general factor of body, facial, and sexual (genital and breast) items, and a second factor assessing weight and/or its body correlates-the hips, thighs, and buttocks. Also, a method factor, a response style of negativity, may be important. Body image attitudes are correlated with some conceptually relevant criteria, such as interest in engaging in sexual activity; however, these relationships do not appear sufficiently strong to predict behavior, such as the occurrence or resolution of sexual dysfunction. Generalized body image disturbance as currently conceptualized and assessed may be difficult to document, particularly when item content and response styles are considered.     

Back and Forth and Beyond

The Journal invited Tom Andersen, author of major pioneering work on the reflecting team, and his colleagues, to offer comment on The Reflecting Team Process in Training. We thought such a north-south dialogue was in keeping with the spirit of reflecting teams, and the team members in Melbourne and Tromsø agree — Editor.     

An Alternative Exact Solution of the Two-Stage Clonal Growth Model of Cancer

The approximate solution of the two-stage clonal expansion model of cancer may substantially deviate from the exact solution, and may therefore lead to erroneous conclusions in particular applications. However, for time-varying parameters the exact solution (method of characteristics) is not easy to implement, hampering the accessibility of the model to nonmathematicians. Based on intuitive reasoning, Clewell et al. (1995) proposed an improved approximate solution that is easy to implement whatever time-varying behavior the parameters may have. Here we provide the mathematical foundation for the approximation suggested by Clewell et al. (1995) and show that, after a slight modification, it is in fact an exact solution for the case of time-constant parameters. We were not able to prove that it is an exact solution for time-varying parameters as well. However, several computer simulations showed that the numerical results do not differ from the exact solution as proposed by Moolgavkar and Luebeck (1990). The advantage of this alternative solution is that the hazard rate of the first malignant cell can be evaluated by numerically integrating a single differential equation.     

Social Class,Economic Inequality,and the Convergence of Policy Preferences: Evidence from 24 Modern Democracies

Using data from the World Values Survey and national‐level indicators for 24 modern democracies, we assess the influence of social class and economic inequality on preferences for government responsibility. We improve on previous research by using multilevel models that account for differences in attitudes both within (i.e., over time) and across countries. Our findings are consistent with the economic self‐interest hypothesis. Specifically, working class individuals, who tend to gain the most from government intervention because of their low and often more precarious economic position, are more likely than others to support government intervention. We also find a positive relationship between national‐level income inequality and support for government intervention. As income inequality rises, its social ills tend to be more pervasive, resulting in public opinion becoming more supportive of governments taking responsibility for their citizens. We further demonstrate that inequality moderates the relationship between social class and attitudes. Although the effect of income inequality is positive for all social classes, attitudes across social classes become more similar as inequality rises. Utilisant les données de World Values Survey et indicateurs de niveau national, nous évaluons l'influence de la classe sociale et l'inégalité économique sur les préférences en matière de responsabilité du gouvernement dans 24 démocraties modernes. Notre analyse se améliore sur la recherche précédente en utilisant des modèles à plusieurs niveaux qui tiennent compte des différences dans les attitudes au sein (ce est à dire, au fil du temps) et entre les pays. Nos résultats sont cohérents avec l'hypothèse d'auto‐ intérêt économique. Par exemple, les travailleurs ‐ qui ont tendance à bénéficier plus quand le gouvernement intervient dans l’économie en raison de leurs faibles revenus et souvent position plus précaire ‐ sont plus susceptibles que d'autres à un soutien responsabilité du gouvernement. Nous constatons également une relation positive entre l'inégalité des revenus au niveau national et le soutien à l'intervention du gouvernement. Comme l'inégalité des revenus se élève—et ses maux sociaux ont tendance à être plus répandue—l'opinion publique devient plus favorable des gouvernements assument la responsabilité de citoyens. Tout aussi important, cependant, nous démontrons également que la relation entre la social classe et les préférences pour la responsabilisation du gouvernement diffèrent par la quantité de l'inégalité des revenus dans un pays. Bien que l'effet de l'inégalité des revenus est positif pour toutes les classes sociales, les différences dans les attitudes de la classes sociale convergent que l'inégalité augmente.
