Misconduct versus Honest Error and Scientific Disagreement

Researchers sometimes mistakenly accuse their peers of misconduct. It is important to distinguish between misconduct and honest error or a difference of scientific opinion to prevent unnecessary and time-consuming misconduct proceedings, protect scientists from harm, and avoid deterring researchers from using novel methods or proposing controversial hypotheses. While it is obvious to many researchers that misconduct is different from a scientific disagreement or simply an inadvertent mistake in methods, analysis or misinterpretation of data, applying this distinction to real cases is sometimes not easy. Because the line between misconduct and honest error or a scientific dispute is often unclear, research organizations and institutions should distinguish between misconduct and honest error and scientific disagreement in their policies and practices. These distinctions should also be explained during educational sessions on the responsible conduct of research and in the mentoring process. When researchers wrongfully accuse their peers of misconduct, it is important to help them understand the distinction between misconduct and honest error and differences of scientific judgment or opinion, pinpoint the source of disagreement, and identify the relevant scientific norms. They can be encouraged to settle the dispute through collegial discussion and dialogue, rather than a misconduct allegation.     

Former system youth with mental health needs: Routes to adult mental health care, insight, emotions, and mistrust

Objective

Public health concern surrounding the mental health needs of former system youth is escalating. We know very little about mental health service utilization on the other side of the developmental transition to adulthood. The purpose of this study was to explore the mental health service use experiences among former system youth with childhood histories which included mental disorder, use of publicly-funded mental health services, and use of additional public systems of care.

Methods

In-depth face-to-face interviews were conducted with 60 participants currently struggling with mental health difficulties regarding their service use experiences over the transition. Participants were recruited from one Midwestern state. Multi-phase analysis was conducted utilizing immersion/crystallization, constant comparison and concept matrices.

Results

Few participants received continuous mental health care across the transition, with the majority experiencing interruptions or discontinuation of care. Important facilitators of service use emerged, such as physicians, former caseworkers and family. Health clinics and parenting programs emerged as potential entrée points for reconnecting disengaged young adults to mental health services. Insight, mistrust, and emotions emerged as novel factors associated with service utilization among young adults.

Conclusions

Mental health service utilization remains a complicated phenomenon over the developmental transition to adulthood. Future research is needed that closely examines the associations between insight, emotion, mistrust and service use among young adults.     

Household Structure and Children's Educational Attainment: A Perspective on Coresidence with Grandparents

Children from alternative households complete fewer years of schooling. Yet little is known about the implications of coresidence with grandparents for educational attainment. Using data from the National Longitudinal Study of Adolescent Health (N = 10,083), this study found that extended households with two biological parents were not detrimental to high school completion or college enrollment. Although coresidence with grandparents did not compensate for not living with two biological parents, it seemed to be beneficial for the educational attainment of youth from single‐mother households. In contrast, skipped‐generation households were associated with a persistent disadvantage for educational attainment. Limited socioeconomic resources partially accounted for the adverse effects of alternative households, whereas parenting quality did not explain these effects. Interactions of gender by household structure suggested that stepfather households could have negative consequences for high school completion and college enrollment only for girls.     

Riester-Vertr?ge: Zur Bedeutung von Kosten und Garantien aus Anlegersicht

The article discusses insurance- and mutual fund-based Riester contracts with respect to the different cost structures and the nominal capital guarantee. A mutual fund-based contract is represented by a plan with a high equity exposure and a nominal capital guarantee, while an insurance-based contract is approximated by a contract with a lower equity exposure and a guaranteed annual rate of return of 2.25%. Both approaches are implemented using a constant proportion portfolio insurance (CPPI) strategy to ensure the relevant capital guarantee. Without taking cost into account, mutual fund-based contracts seem to be the preferred choice for large segments of the population. However, insurance-based Riester contracts become more attractive once the differences in the cost structures are taken into account. The cost disadvantage of mutual fund-based Riester contracts, which occurs whenever the active managers cannot beat the market, is especially important for weakly risk-averse investors, i.e. for the classic clientele of risky investments. Similarly, these savers suffer most from the nominal capital guarantee of mutual fund-based contracts because these individuals would prefer a constant-mix strategy over a CPPI strategy. Thus, the differences in cost structure and the nominal capital guarantee can be identified as possible reasons for the persistently high market shares of insurance-based contracts in the Riester market. However, mutual fund-based Riester contracts are still the first choice for many savers. For example, people with relatively secure private property outside a Riester contract would prefer mutual fund-based contracts, despite cost and capital guarantee issues. The results suggest that mutual fund-based Riester contracts that use Exchange Traded Funds are an attractive product innovation in the Riester market.     

Forecasts of population in the United States

In this paper the author discusses the work of the Division of the U.S. Bureau of the Census, which is concerned with forecasting populations. He traces the development of these activities and considers some of the actual forecasts that have been made.     

Rasch measurement and differences between women and men in self-esteem

Most researchers who investigate sociological influences on emotional well-being or distress employ correlational methods as justification for the scales used as measures of distress (factor analysis) and to describe the effects of various factors on distress (regression). This paper suggests that log-linear and related models offer certain advantages over the linear model which have largely been ignored. An analysis of the cross-classification of items included in a widely used measure of self-esteem suggests that one of the items must be eliminated to approximately achieve measurement as defined by Rasch. The resultant latent variable shows no difference in self-esteem between women and men. An analysis of the additive index which includes all of the items, however, reveals that women have lower self-esteem than do men. This apparent difference results solely from a difference on the discrepant item: women are less likely than men to report that they often, rather than sometimes or rarely, can do things as well as most other people.     

Race,Political Empowerment,and Minority Perceptions of Judicial Fairness*

Objective. Recent studies of the impact of black elite electoral success on the system‐supporting attitudes of black citizens have yielded mixed, but generally unimpressive, empirical results. We extend this limited research by examining the effects of the presence of black judicial officials on public attitudes toward a state judicial system. Methods. We employ data from a telephone survey of citizens in Mississippi and develop multivariate models to test for the effects of black judges on citizens' evaluations of the fairness of judges, equity in sentences, and overall impartiality of the state judicial system. Results. We find no systematic evidence that the election of black judicial officials ameliorates the suspicions of the black public regarding the fairness of the state courts. Conclusions. Our findings are in line with other recent studies on the limited effects of black elite electoral success on the attitudes of the black public and generally support a “political reality” model of political trust rather than an “empowerment model.”     

A note on optimum linear feature extraction for gaussian populations with equal covariances and equal a priori probabilities

We consider the linear feature selection problem of obtaining a nonzero 1 × n matrix B which minimizes the probability of misclassification based on the Bayes decision rule applied to the random variable Y = BX, where X is a random n-vector arising from one of m Gaussian populations with equal covariances and equal apriori probabilities. It is shown that the optimal B satisfies a fixed point equation B = F(B) which can be solved by successive substitution.
