Religion,Religiosity, and the Attitudes Toward Homosexuality—A Multilevel Analysis of 79 Countries

Although attitudes toward homosexuality have become more liberal, particularly in industrialized Western countries, there is still a great deal of variance in terms of worldwide levels of homonegativity. Using data from the two most recent waves of the World Values Survey (1999–2004, 2005–2009), this article seeks to explain this variance by means of a multilevel analysis of 79 countries. We include characteristics on the individual level, as age or gender, as well as aggregate variables linked to specificities of the nation-states. In particular, we focus on the religious denomination of a person and her religiosity to explain her attitude toward homosexuality. We find clear differences in levels of homonegativity among the followers of the individual religions.     

Propensity score prediction for electronic healthcare databases using super learner and high-dimensional propensity score methods

ABSTRACT

The optimal learner for prediction modeling varies depending on the underlying data-generating distribution. Super Learner (SL) is a generic ensemble learning algorithm that uses cross-validation to select among a ‘library’ of candidate prediction models. While SL has been widely studied in a number of settings, it has not been thoroughly evaluated in large electronic healthcare databases that are common in pharmacoepidemiology and comparative effectiveness research. In this study, we applied and evaluated the performance of SL in its ability to predict the propensity score (PS), the conditional probability of treatment assignment given baseline covariates, using three electronic healthcare databases. We considered a library of algorithms that consisted of both nonparametric and parametric models. We also proposed a novel strategy for prediction modeling that combines SL with the high-dimensional propensity score (hdPS) variable selection algorithm. Predictive performance was assessed using three metrics: the negative log-likelihood, area under the curve (AUC), and time complexity. Results showed that the best individual algorithm, in terms of predictive performance, varied across datasets. The SL was able to adapt to the given dataset and optimize predictive performance relative to any individual learner. Combining the SL with the hdPS was the most consistent prediction method and may be promising for PS estimation and prediction modeling in electronic healthcare databases.     

Predicting Condom Use Outcomes via the Information Motivation Behavioral Skills Model: An Analysis of Young Black Men

Objectives: This study examines the relationships between information motivation behavioral skills model constructs and their associations with consistent condom use and condom use problems among young Black men. Methods: The authors use baseline data collected from 702 participants in a randomized controlled trial. Analyses involved path modeling and bootstrapped standard errors to estimate associations. Results: Motivation had the largest association with consistent condom use, whereas condom application skills had the largest association with condom use problems. Conclusion: Motivation is the most important predictor of consistent condom use, whereas condom application skills are the most important predictor of condom use problems.     

Führungsstile – Evaluation einer Nebenaufgabe im Development Center

To asses six different leadership styles we employed a questionnaire during the development center in a manufacturing firm. Analysing the questionnaire indicates its reliability, scalability, economy, usefulness and fairness. An explorative factor analysis supports the factorial validity. A content analysis provides evidence that the transformational leadership style is perceived as the most positive and the authoritarian leadership style as the most negative one. Furthermore, we found transformational leadership style positively correlated with an aggregated measure for the competence extraversion.     

Parents' experiences with child protection during pregnancy and post-birth

Limited research has directly sought the input of parents involved in the child protection system during pregnancy and with their infants. As the focus of these policies and practices, parents have a unique and important insight not available to others, so it is vital to obtain their input. As part of a larger Australian study, qualitative interviews were undertaken with 13 parents asking about their views and experiences. Parents predominantly became involved with child protection services during pregnancy through a prenatal report. Parents who previously had their newborn removed from their care described it as sudden and unexpected, leaving them distressed and unsupported post-removal, with a growing list of requirements for them to see their baby or for restoration to be considered. Domestic violence was a particular issue of concern for some mothers who expressed distress that their partners, perpetrators of violence, were allowed access to their infant with fewer requirements than for them. Improvements recommended by the parents included greater communication and preparation for the removal, better recognition of improvements in their situations and increased supports to be provided to parents both pre- and post-removal. Parental experiences provide an important guide to improving child protection practice with these families.     

Joint measurement of risk aversion,prudence, and temperance

Risk aversion—but also the higher-order risk preferences of prudence and temperance—are fundamental concepts in the study of economic decision making. We propose a method to jointly measure the intensity of risk aversion, prudence, and temperance. Our theoretical approach is to define risk compensations of different orders, and in an experiment we elicit these compensations with a price list technique. We find evidence for risk aversion, prudence, and temperance. These traits correlate within subjects. The compensations elicited for prudence are significantly larger than those for risk aversion and temperance. In contrast to commonly used utility functions, prospect theory can predict this behavioral pattern. In our experiment, risk-averse, risk-loving, and risk-neutral subjects are prudent. This supports a recent theoretical observation that prudence may be a more universal trait than previously realized.     

Seeking Closure: Competition in Complementary Markets*

When offering a product that has a complementary product in a different market, a firm must consider the interdependence between the complementary products as well as the competition within markets. If the firm participates in both markets, the balancing act becomes even more challenging. This article provides insights about strategies in this latter setting: when should the firm seek to keep its products closed to competing complementary products, and when would the firm be better off by accepting a common standard? To address these questions, we employ standard game theoretic analysis to a simple spatial model that captures aspects of both intermarket externalities and intramarket competition. We find that if a firm participates in both markets and chooses a closed standard, it achieves lower profits compared to an open standard, but gains greater market share. Surprisingly, we find that customers are better off when standards are kept closed.     

Steuerreformen durch Tarif-oder Zeiteffekte? Eine Analyse am Beispiel der Thesaurierungsbegünstigung für Personenunternehmen

Zusammenfassung  Der Beitrag diskutiert Tarif- und Zinseffekte anhand der begünstigten Besteuerung nicht entnommener Gewinne von Personengesellschaften, die 2008 in Deutschland eingeführt wurde. Bei Eigenfinanzierung und Betrachtung von Grenzsteuers?tzen zeigt der Beitrag, dass die Thesaurierungsbegünstigung stets nachteilig ist, wenn eine abgeltend besteuerte private Kapitalmarktanlage die Alternativanlage darstellt. Müssen Gewinne thesauriert werden, weil Mittel im Unternehmen ben?tigt werden, so entf?llt die private Alternativanlage und die Thesaurierungsbegünstigung kann bei hohen Zins- und Steuers?tzen vorteilhaft sein. Wird die Einkommensteuerprogression berücksichtigt, zeigt der Beitrag, dass bei schwankenden Gewinnen die Thesaurierungsbegünstigung oftmals vorteilhaft ist, auch gegenüber der Abgeltungsteuer. Bei fremdfinanzierten Investitionen kann die Inanspruchnahme der Thesaurierungsbegünstigung sehr vorteilhaft sein, da die geringere Steuerzahlung bei Gewinnanfall den Umfang des ben?tigten Fremdkapitals mindert. Insgesamt zeigt sich, dass sich Reformen von Steuertarifen wesentlich st?rker auf die Vorteilhaftigkeit von Investitionen auswirken als Zinseffekte.

Tax reforms by tax rate effects or timing effects? An analysis based an the German tax privilege for retained earnings

Summary  This paper analyzes two typical effects of tax reforms, tax rate effects and timing effects. The example chosen for the analysis is the tax privilege for retained profits of partnerships and sole proprietorships, which was implemented in Germany in 2008. Taking equity-financing and top marginal tax rates into account, the so-called tax privilege turns out to be a disadvantage under most assumptions. If the alternative investment is private capital income taxed at a flat-rate tax, the tax privilege will always be disadvantageous. If profits have to be retained and business income is the alternative investment, then the tax privilege will be advantageous in case of high income tax rates and interest rates. Analyzing progressive tax rates instead of top marginal tax rates reveals favorable results in case of fluctuating profits if the tax privilege is claimed. The same is true if debtfinancing is taken into account. All in all, the paper shows that a reform of tax rates influences the attractiveness of investments much more compared to timing effects.
