Psychopathic Personality Traits and Delinquent and Risky Sexual Behaviors in Croatian Sample of Non-referred Boys and Girls

The current study investigated the association of psychopathic traits with violent and non-violent delinquency, delinquency versatility, and risky sexual behavior in Croatian sample of non-referred boys (n = 226) and girls (n = 480). Psychopathic traits were measured by the self-report Youth Psychopathic Traits Inventory (YPI). Consistent with the study’s hypotheses, Impulsive-Irresponsible and Callous-Unemotional dimensions were most consistently associated with all outcome measures. Results of the regression analyses showed that the Impulsive-Irresponsible behavioral style had stronger association with non-violent delinquency and delinquency versatility for boys. However, the Impulsive-Irresponsible dimension had stronger influence on risky sexual behavior for girls compared with boys. The results of a two-group confirmatory factor analysis revealed that the three-factor model of the YPI was invariant across gender.     

Impact of takeovers on profitability of target companies: Evidence from Croatian companies

It is possible to find scientific confirmation of positive, negative or neutral influence of takeovers on company's profitability. Therefore, this study aimed to highlight the sensitivity of research results on manipulation in terms of used methodology and indicators. Using t-test for paired samples and five selected profitability indicators for target and peer companies, it has been proven that it is possible to obtain significantly different results even when using the same sample and the same reference period. The research has been performed on the sample of Croatian companies, which were taken over in the period from year 2003–2008.     

Y chromosome STR polymorphisms in a Serbian population sample

Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393) were analyzed in the sample of 114 unrelated males living in Serbia. A general STR allelic frequency pattern in Serbians corresponds to other European populations with the exception of loci DYS19, DYS389II and DYS385. Out of ninety identified haplotypes, 74 (64.91%) appeared in single copies. The most frequent haplotypes (DYS19-DYS385-DYS389I-DYS389II-DYS390-DYS391-DYS392-DYS393) 16-14/15-13-31-24-11-11-13 and 15-15/19-12-28-23-10-12-12 were found in four copies (3.51%). Total haplotype diversity was 0.9947+/-0.0021.
