Expressing Induced Emotions Through Free Dance Movement

The aim of this study was to examine the effect of two basic emotions, happiness and sadness, on dance movement. A total of 32 adult participants were induced to feel emotional states of either happiness or sadness and then danced intuitively to an emotionally ‘neutral’ piece of music, composed specifically for the experiment. Based on an Effort-Shape analysis of body movement, full body movement was captured and seven different movement cues were examined, in order to explore whether differences in corporeal articulations between the happy and sad condition existed. Results revealed that in the happy condition, participants moved faster, with more acceleration, and made more expanded and more impulsive movements than in the sad condition. Results are discussed with respect to possible consequences for future research on human movement.     

On Bayesian estimators in multistage binomial designs

A new class of Bayesian estimators for a proportion in multistage binomial designs is considered. Priors belong to the beta-J distribution family, which is derived from the Fisher information associated with the design. The transposition of the beta parameters of the Haldane and the uniform priors in fixed binomial experiments into the beta-J distribution yields bias-corrected versions of these priors in multistage designs. We show that the estimator of the posterior mean based on the corrected Haldane prior and the estimator of the posterior mode based on the corrected uniform prior have good frequentist properties. An easy-to-use approximation of the estimator of the posterior mode is provided. The new Bayesian estimators are compared to Whitehead's and the uniformly minimum variance estimators through several multistage designs. Last, the bias of the estimator of the posterior mode is derived for a particular case.     

Bayesian adaptive dose‐escalation designs for simultaneously estimating the optimal and maximum safe dose based on safety and efficacy

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs.     

Is there a global super-bourgeoisie?

In recent decades, accelerating processes of globalization and an increase in economic inequality in most of the world's countries have raised the question of the emergence of a new bourgeoisie integrated at the global level, sometimes described as a global super-bourgeoisie. This group would be distinguished by its unequaled level of wealth and global interconnectedness, its transnational ubiquity and concentration in the planet's major global cities, its specific culture, consumption habits, sites of sociability and shared references, and even by class consciousness and capacity to act collectively. This article successively discusses how the social sciences have examined these various dimensions of the question and begun to provide systematic empirical answers.     

CREDIT,WAGES, AND BANKRUPTCY LAWS

We analyze how bankruptcy laws affect the general equilibrium interactions between credit and wages. Soft laws reduce the frequency of liquidations and thus ex post inefficiencies, but they worsen credit rationing ex ante. This hinders firm creation and thus depresses labor demand. Rich agents who need few outside funds can invest even if creditor rights are weak. Hence, they favor soft laws that exclude poorer agents from the credit market and reduce the competition for labor. Such laws can generate greater utilitarian welfare than under perfect contract enforcement: By barring access to credit to some agents, soft laws lower wages, which increases the pledgeable income of richer agents and decreases the liquidation rates they must commit to. When they induce strong credit rationing, however, soft laws are Pareto‐dominated by tougher laws combined with subsidies to entrepreneurs. (JEL: D82, G33, K22)     

A Review of: “Dattilio,Frank M. (2010). Cognitive-Behavioral Therapy with Couples and Families: A Comprehensive Guide for Clinicians.”

This conceptual study focuses on health disparities among African Americans in the Arkansas Delta. The author uses an ecosocial perspective to explore several social and individual-level influences upon patients' perceptions of health care quality, including health beliefs and life experiences of discrimination that can lead to not accessing health care systems. The study findings identify community-based strengths that can inform the development of strategies and programs to reduce rural health disparities. The discussion includes the potential implications of the Patient Protection and Affordable Care Act for progress in health care quality and health equality, especially for rural racial/ethnic minorities.     

Employability of Young Italian Men after a Jobless Period, 1989–98

In this paper we investigate the existence of negative jobless duration dependence and the impact of jobless spells on future wages. Our findings are somewhat out of line compared with analogous explorations. We find evidence of very long unemployment duration of the young male labor force, higher than reported anywhere else in Western Europe, as well as large negative unemployment duration dependence. On the other hand, young Italian men experiencing jobless periods in their early careers face small re‐employment wage losses. Such losses do increase with the duration of joblessness, but they are lower than reported in the USA, Canada, the UK, France, and Spain.     

Capital Mobility and Asset Pricing

We present a model for the equilibrium movement of capital between asset markets that are distinguished only by the levels of capital invested in each. Investment in that market with the greatest amount of capital earns the lowest risk premium. Intermediaries optimally trade off the costs of intermediation against fees that depend on the gain they can offer to investors for moving their capital to the market with the higher mean return. The bargaining power of an investor depends on potential access to alternative intermediaries. In equilibrium, the speeds of adjustment of mean returns and of capital between the two markets are increasing in the degree to which capital is imbalanced between the two markets, and can be reduced by competition among intermediaries.     

Die Transformation der Jugendhilfe in Ostdeutschland im Kontext von Tradition, Diskontinuität und Strukturbildung

Changes in the child care legislation in 1990 led to the development of a new helping culture both in West and East Germany at the same time. Paternalistic relations to the clients had to be replaced by autonomy focused and thus professional interaction patterns. So clients were involved in the process of choosing adequate educational support. By comparing two East German youth welfare agencies we show the factors that impede the process of restructuring an appropriate professional-client relationship. The most important factor is the fallacy of mistaking educational support for education itself.
