Plastic face reconstruction as a possibility for identifying unknown skulls (II). An evaluation of the reliability of the reconstruction technic by a double-blind trial

In a double blind-trial two examiners reconstructed the soft tissue on lifelike casts of 12 skulls. They worked independently after having been given information about age, sex and constitution of the person in question and following a reconstruction plan based on the morphology of the skull. The comparison of the completed reconstruction with each other chiefly showed approximate to far-reaching degrees of resemblance and conformity. The comparison of reconstructions and photographs of the individuals also showed predominantly approximate to far-reaching likeness of the general impression, and, with one exception, at least little likeness was achieved. The reconstruction of soft tissue on the skull proved to be a relatively useful method of identifying unknown skulls, provided information on the colour and length of the hair, and possibly on the hairstyle as well, is at the examiner's disposal.     

Tax authority to the European Parliament?

In this paper we analyze whether countries of the EC community should plead for a decentralized system to finance the European funds rather than using a uniform tax imposed by the European parliament. The analysis is within a multistage game-theoretic framework in which the implication of the financing system of a confederation on the investment behavior in the respective states is considered. The paper is in the tradition of the literature which claims that from a view of global efficiency property-rights structures inducing ex-post efficient allocations may be worse than a system leading to an ex-post inefficient allocation. For this specific economic issue we elucidate the tradeoff between incentive effect and distributional policy. Especially we demonstrate that rather homogeneous countries benefit by installing a central tax institution. If the countries are rather heterogeneous, the countries may have opposing interests with respect to the answer of the question which is presented in the title. It is possible that the “high-developed” country prefers to install a central tax authority while the “low-developed” country does not. However, in general the reverse ordering which is more in line with our intuition results.     

Gender-specific pathways to intimacy in early adolescence

As part of a larger longitudinal study of psychosocial development, 148 girls and 130 boys were administered a series of questions regarding a close friend during their eighth-grade school year. Scales corresponding to shared experience, self-disclosure, and intimacy (defined as emotional closeness) were developed from these items. Path-analytic models tested the relative strength of the self-disclosure and shared experience paths to emotional closeness for boys and girls separately. The results indicated that the self-disclosure path to emotional closeness is significant for both boys and girls. No relationship was found between shared experience and emotional closeness in girls when controlling for self-disclosure. The relationship between shared experience and feelings of closeness was, however, significant for boys even while controlling for the effects of self-disclosure. Covariance structure analysis (LISREL) indicated that the covariance matrices for the three scales were significantly different for boys and girls. The results are considered in relation to the gender socialization and friendship literature. The potential importance of defining intimacy as emotional closeness is also discussed.The research reported here was supported by National Institute of Mental Health Grant MH30252/38142 to Anne C.

Measurement of the psychological well-being of adolescents: The psychometric properties and assessment procedures of the how I feel

The assessment procedures and psychometric properties of the How I Feel (HIF), an instrument used to assess psychological well-being in a population of Black adolescents are described. The audiovisual mode of presentation obviates problems related to reading skill; in addition, it standardizes the administration of the instrument. The How I Feel appears to measure reliably and validly several multi-item constructs representing psychological well-being. These constructs relate to other instruments and constructs in meaningful and interesting ways. A major result of our validity studies is that there appear to be two major components of psychological well-being, psychopathology and self-esteem.Research presented in this paper is from the Social Psychiatry Study Center, Department of Psychiatry, University of Chicago and was supported by a grant from the National Institute on Drug Abuse (DA-00787).Received her Ph.D. from the University of Chicago.

Winning Faces Vary by Ideology: How Nonverbal Source Cues Influence Election and Communication Success in Politics

Not just the content of a communication but also the source of the communication shapes its persuasiveness. Recent research in political communication suggests that important source cues are nonverbal and relate to the physical traits of the source such that attractive- and competent-looking sources have better success in attracting votes and policy support. Yet, are all nonverbal source cues similarly received irrespective of audience, or does their reception vary across audiences? Specifically, we ask whether some physical traits are received positively by some audiences but backfire for others. Utilizing research on ideological stereotypes and the determinants of facial preferences, we focus on the relationship between the facial dominance of the source and the ideology of the receiver. Across five studies, we demonstrate that a dominant face is a winning face when the audience is conservative but backfires and decreases success when the audience is liberal. On the other hand, a non-dominant face constitutes a winning face among liberal audiences but backfires among conservatives. These effects seemingly stem from deep-seated psychological responses and shape both the election and communication success of real-world politicians. If the faces of politicians do not match the ideology of their constituency, they are more likely to lose in the competition for votes and policy support.     

Citizens' Blame of Politicians for Public Service Failure: Experimental Evidence about Blame Reduction through Delegation and Contracting

Theories of blame suggest that contracting out public service delivery reduces citizens’ blame of politicians for service failure. The authors use an online experiment with 1,000 citizen participants to estimate the effects of information cues summarizing service delivery arrangements on citizens’ blame of English local government politicians for poor street maintenance. Participants were randomized to one of four cues: no information about service delivery arrangements, politicians’ involvement in managing delivery, delegation to a unit inside government managing delivery, and delegation through a contract with a private firm managing delivery. The politicians managing delivery cue raises blame compared to citizens having no information. However, the contract with a private firm cue does not reduce blame compared to either no information or the politicians managing delivery cue. Instead, the delegation to a unit inside government cue reduces blame compared to politicians managing delivery, suggesting that delegation to public managers, not contracting, reduces blame in this context.     

National Varieties of Public–Private Partnerships (PPPs): A Comparative Analysis of PPP-Supporting Units in 19 European Countries

Most countries that have adopted the public–private partnership (PPP) model as a means of implementing infrastructure projects have launched dedicated supporting units to guide policy development and stimulate project implementation. This paper draws on the theoretical notion of PPP-enabling fields to carry out a comparative analysis of the roles and functions of PPP-supporting units across 19 European countries with varying PPP experiences. We distinguish four categories of national support of PPPs, from skeptical systems of zero support to full-fledged PPP systems. Furthermore, we take initial steps to analyze the possible link between national differences in institutionalized PPP support and the amount of implemented PPP projects. Finally, pathways for further research on PPP-supporting units are discussed.     

The economic effects of constitutions: replicating—and extending—Persson and Tabellini

Persson and Tabellini (The Economic Effects of Constitutions, The MIT Press, Cambridge, 2003) show that presidential regimes and majoritarian election systems have important economic effects. Here, the number of countries is expanded and more recent data is used. In replicating and extending their analyses, we find that the effect of presidential regimes vanishes almost entirely. With regard to electoral systems, the original results are largely confirmed: majoritarian (as opposed to proportional) electoral systems lead to lower government expenditure, lower levels of rent seeking but also lower output per worker. The institutional details, such as the proportion of candidates that are not elected on party lists and district size, are particularly important.
