KNOWLEDGE OF NONVERBAL CUES,GENDER, AND NONVERBAL DECODING ACCURACY

The Test of Nonverbal Cue Knowledge (TONCK), a paper and pencil test measuring explicit knowledge of nonverbal cue meanings and uses, was developed and found to be reliable and to have predictive ability. In four studies, participants were given the TONCK and one or more tests of accuracy in decoding nonverbal cues the adult faces and voices tests of the Diagnostic Analysis of Nonverbal Accuracy 2 (DANVA) and the video and audio tests of the Profile of Nonverbal Sensitivity (PONS), as well as a test of general cognitive ability (the Wonderlic Personnel Test). Results are reported for the four studies individually and also in a meta-analytic summary. Females scored higher than males on the TONCK and on the PONS, and the TONCK predicted accuracy on the PONS and DANVA. Knowledge of nonverbal cues did not account for the gender difference in decoding ability on the PONS. Cognitive ability was related to the TONCK but did not compromise relations with other variables. The future utility of the TONCK, content specificity of tests, as well as the automaticity of judging cues are discussed.The authors thank Crystal Mileti, Jenna Lavery, Erica Dempsey, and Jared Majerle for their assistance in conducting this research.     

Conceptualizing Resistance

Recently, there has been a rapid proliferation of scholarship on resistance but little consensus on its definition. In this paper, we review and synthesize the diverse literatures that invoke the concept of resistance. This review illuminates both core elements common to most uses of the concept and two central dimensions on which these uses vary: the questions of whether resistance must be recognized by others and whether it must be intentional. We use these two dimensions to develop a typology of resistance, thereby clarifying both the meaning and sociological utility of this concept.     

“Trees Die From the Top”: International Perspectives on NGO Leadership Development

This paper examines the role of leadership development in NGO capacity building and assesses some of the challenges of developing a new generation of NGO leaders. The paper draws on the analysis of new and existing research into the dimensions of NGO leadership highlighting the importance of both individual attributes and contextual relevance. Effective NGO leaders are able to balance a range of competing pressures from different stakeholders in ways that do not compromise their individual identity and values. Leadership development programmes therefore need to focus on both the values and identity of individual leaders while also assisting leaders understand and proactively respond to their rapidly changing external environment. We conclude that there is an urgent need to build the capacity of NGOs to develop their leadership capability. Unless systems and processes to support this work are put in place then the apocryphal warning trees die from the top will have more than a ring of truth in it.     

Lepidoptera-habitat relationships in urban parks

We examined the relationships among Lepidopteran species richness and relative abundance, field and park size, and herbaceous plant richness and cover in parks of New York, NY. Lepidopteran populations and habitats were quantified from 1 June–30 September 2002 in fields of 8 New York City (NYC) parks. We observed 42 species of Lepidoptera, with park size, field size, and plant species richness positively related to Lepidopteran abundance and species richness. Several plant species received heavy use and appeared to be important to Lepidoptera in this urban environment, particularly butterfly-bush (Buddleia davidii), mugwort (Artemisia vulgaris), knapweed (Centaurea maculosa), and clover (Trifolium spp.).     

Get High and Get Stupid: The Effect of Alcohol and Marijuana Use on Teen Sexual Behavior

Numerous studies have documented a strong correlation between substance use and teen sexual behavior, and this empirical relationship has given rise to a widespread belief that substance use causes teens to engage in risky sex. This causal link is often used by advocates to justify policies targeted at reducing substance use. Here, we argue that previous research has not produced sufficient evidence to substantiate a causal relationship between substance use and teen sexual behavior. Accordingly, we attempt to estimate causal effects using two complementary research approaches. Our findings suggest that substance use is not causally related to teen sexual behavior, although we cannot definitively rule out that possibility.Research for this paper was supported by grant number 5 R01 DA12692 from the National Institute on Drug Abuse to the National Bureau of Economic Research.

How Welfare Reform Can Affect Marriage:Evidence from an Experimental Study in Minnesota

A stated goal of the welfare legislation of 1996 was to develop policies to encourage the formation and maintenance of two-parent families, yet states were given little guidance about how to do this. Experimental evidence from the Minnesota Family Investment Program (MFIP), a program that tested the effects of an enhanced earnings disregard designed to encourage work and reduce poverty, shows that welfare policies can produce important effects on marital behavior even without explicit strategies aimed to do so. Three years after study entry, MFIP increased marriage rates among single parent long-term recipients and increased marital stability among two-parent recipient families. Similar effects were not found among newer applicants to welfare, possibly because many of these families leave welfare quickly. Replicating programs like MFIP in different settings and understanding why applicants responded differently will be essential to informing the policy significance of these findings.This research was supported by funding from the Minnesota Department of Human Services, the Ford Foundation, the US Department of Health and Human Services, the US Department of Agriculture, the Charles Stewart Mott Foundation, the Annie E.

Vanishing senses—restoration of sensory functions by electronic implants

Is the endeavour to restore perceptive brain functions by electronic implants the first step on the way to create bionic cyborgs? Can we augment or multiply our senses by directly contacting computer chips to the brain? Will bio-implants influence and permanently change human psyche?Almost 50 years ago, the foundation of the new field of neuroprosthetics propelled research aimed at devising a seamless connection between the human nervous system and microelectronic implants.The complexity of sensory perception often renders the task of assessing efficacy and side effects of a sensory implant impossible when computer simulation and animal experimentation alone are employed. Historical development in this field has shown that some of the evaluation has to be done in investigations performed directly in the human.The consequences of such a technology will not be confined to medicine alone. This paper describes its development, state of the art, limiting factors, and future possibilities. It offers an introduction into the elementary prerequisites of neural interfacing as a basis for argumentation in the upcoming public debate.The advancement of sensory implants for the restitution or augmentation of impaired brain function requires a moral and ethical position not only of the scientist involved, but of all the society, similar to the fields of psychopharmacology and stem cell research.     

Comparing the Fisher information in record data and random observations

We compare the Fisher information (FI) contained in the firstn record values and record times with the FI inn i. i. d. observations. General results are established for exponential family and Weibull type setups, and a summary table is provided listing several common distributions. We show that the FI in record data improves notably once the record times are included, often changing from being less to being equal or greater than the FI in a random sample of the same size. The behavior in the Weibull case is surprising. There it depends onn, whether the record or the i.i. d. observations have more FI. We propose new estimators based on record data. The results may be of interest in some life testing situations. Supported in part by Fondo Nacional de Desarrollo Cientifico y Tecnologico (FONDECYT) grant # 1010222 of Chile.     

Eine Forschungsstudie zum Elternkurs des Deutschen Kinderschutzbundes e.V. „Starke Eltern — Starke Kinder®“

The course for parents organized by the German Society for the Protection of Children ?Strong parents — strong children“ offers support to parents in their methods of upbringing their children. The effects the participation in this course can have on parents, their children, the family atmosphere and the partents-child relationship were evaluated in a research study at the University of Applied Sciences Cologne.After briefly introducting the course for parents the study ist meant to show how deeply the drawing up of research parameter (i.e. dimensions of education) and the realisation of the evaluation were influenced by the anthropology and dialogical pedagogy of the Polish doctor and pedagogue Janusz Korczak (1878–1942).The contribution describes pedagogical reflections on and the relevant dimensions of the educational methods that encourage respectively inhibit development. The essay then delivers first results of the accompanying research.     

Maximum likelihood estimation of ARFIMA models with a Box-Cox transformation

In this paper we study the interaction between the estimation of the fractional differencing parameter d of ARFIMA models and the common practice of instantaneous transformation of the observed time series. At this aim, we first discuss the effect of a nonlinear transformation of the data on the identification of the process and on the estimate of d. Thus, we propose a joint estimation of the Box-Cox parameter and d by means of a modified normalized version of the Whittle likelihood. Then, the variance and covariance matrix of the parameters estimates is obtained. Finally, a Monte Carlo study is performed in order to check the behaviour of the proposed estimators in finite samples.The paper is the result of a joint research of the two authors.
