Gambling among Croatian young people: an exploratory study of the relationship between psychopathic traits,risk-taking tendencies and gambling-related problems

The present study investigated the relationship between psychopathic traits, risk-taking tendencies and gambling problem severity and if these associations varied by gender in a community sample of Croatian adolescents (N = 282; 148 males). Results of the regression analyses showed that the Impulsive-Irresponsible behavioural style (YPI-II) and the Grandiose-Manipulative interpersonal style (YPI-GM) were the strongest postdictors of gambling-related problems. Surprisingly, independently of the YPI-II dimension, the Callous-Unemotional traits were negatively associated to gambling-related problems. By, contrast, independently of the psychopathic traits, risk-tendencies were not significant postdictors of gambling problem severity. With respect to gender differences, higher levels of the YPI-II and YPI-GM dimensions were related to more severe gambling-related problems only in males, not in females. Furthermore, while the CU traits exhibited protective features against gambling-related problems in both genders, the effect was stronger for males than for females.     

Privatisation Effects: Some Evidence from Serbia

This paper analyses basic outcome and effects of the privatisation process in Serbia. The first two parts of the paper deal with general achievements of the newest privatisation plan adopted in 2001. We present a brief background of the results of the privatisation process, analysing changes in the structure of enterprises by ownership status, the number of privatised firms, revenues earned through privatisation, the rate of successful transactions, and other relevant privatisation indicators. The paper continues with an analysis of a survey conducted within a sample of Serbian enterprises offering some evidence about performance, competition, and restructuring within different types of firms: socially owned, privatised, and new private. Contrary to the broadly accepted statement that new private firms are leading in transition economies, according to our estimation of the effects of the ownership type on firm performance, it appears that the privatised sector seems to be more active. A comparison of the survey results with findings for three neighbouring countries indicates that there is no general conclusion about the way how ownership status of a firm affects its performance in a transition economy. Although conclusions drawn from our survey analysis should be regarded as preliminary and limited by the quality of survey data and could not be generalised for the privatisation process in other transition countries, the findings we present, including the comparison made with other economies, could contribute to the understanding of both privatisation effects in general and effects remarkable for the Serbian economy.      

Serbian Judiciary and Transition: Recent Jurisprudence

This article examines the role and position of national courts during transitional periods with focus on and case study of the judiciary in Serbia. Courts in Serbia, as any other judiciary in transition, have undergone a staggering transformative process as illustrated by a chronology of human rights cases. On the other hand, courts in Serbia, as their counterparts worldwide, have also been the transformation force, as evidenced by recent jurisprudence in cases dealing more or less successfully with political assassinations, organized crime, corruption, war crimes, and international courts.     

What Coy Smiles Say About Positive Shyness in Early Infancy

Positive shyness is a universal emotion with the specific social function of regulating our interactions by improving trust and liking, and showing politeness. The present study examined early infant production of coy smiles during social interactions as a measure of positive shy behavior. Eighty 4‐month‐olds were experimentally observed during three types of interactions in front of a mirror in which (1) the infant only sees him or herself, (2) the infant only sees the other person (mother, father, or stranger), and (3) the infant sees both him or herself and the other person. Infants produced more coy smiles during the interaction with a stranger than during the interactions with their mother or their father, or when they could see only themselves in front of a mirror. Infants also produced more coy smiles when they could see their self‐reflection during the interaction than when they could not. Our results support the assumption that coy smiles indicate an early emerging emotional reaction with an important adaptive function during social situations involving novel persons and when special attention is given to the child.     

Partner Choice in Sweden Following a Failed Intermarriage

This paper is based on the assumption that divorced and separated individuals bring with them the experience of a failed union which may shape their future choices on the marriage market. It aims to contribute to our knowledge of intermarriage, and social interaction in Sweden in general, by comparing the repartnering choices of immigrants and natives in Sweden who had made what is still considered an atypical choice of entering a native-immigrant union with the partner choices of natives and immigrants whose previous union was endogamous. The empirical analysis in this paper is based on the Swedish register data from the STAR data collection (Sweden over Time: Activities and Relations) and covers the period 1990–2007. All the analyses in the paper include individuals aged 20–55 at the time of union dissolution. The multivariate analysis is based on discrete-time multinomial logistic regression. The results show that for all four groups defined by sex and nativity (native men, native women, immigrant men, and immigrant women), there is a positive association between the previous experience of intermarriage and the likelihood of initiating another intermarriage after union dissolution. Another important finding is that the magnitude of this positive association increases with the degree of social distance between the groups involved in the union. Gender differences are modest among natives and somewhat more pronounced among immigrants.     

New Generalizations of Cauchy Distribution

The generalized skew-normal distribution introduced by Balakrishnan (2002 Balakrishnan , N. ( 2002 ). Discussion on ‘Skew multivariate models related to hidden truncation and/or selective reporting’ by B. C. Arnold and R. J. Beaver . Test 11 : 37 – 39 .[Web of Science ®] , [Google Scholar]) is used to obtain new generalizations of univariate Cauchy distribution with two parameters, denoted by GC _{m, n} (a, b) with m and n non-negative integer numbers and a, b ∈ R. For cases (m, n) = (1, 2), (m, n) = (2, 1), (m, n) = (0, 3) and (m, n) = (3, 0) explicit forms of the density functions are derived and compared to previous generalizations of Cauchy and skew-Cauchy distributions.     

On statistical models for multimodal optimization

A new approach for the construction of statistical models for multimodal optimization is proposed; the examples of such models are given. The results of the psychological experiment show that the proposed approach is intuitively acceptable.
