The purpose of the research was to see whether work of special educators and rehabilitators in the regular school has a positive influence on peer relationship among students with delayed cognitive development. The accent was on friendship quality, social competence and antisocial behavior. The research comprised 150 students with slow cognitive development, 52 of who have support of special educators and rehabilitators in regular education, while the remaining 98 students are without support. Friendship quality was evaluated applying Friendship Quality Questionnaire.  School Social Behavior Scale was used in order to evaluate social competence and antisocial behavior. Differences among the groups were examined by t-test from SPSS 14 Windows software package. T he results have shown that students with slow cognitive development having support from special educators and rehabilitators evaluate their friendship more qualitative. Students with delayed cognitive development attending schools without special educators and rehabilitators engaged demonstrate better level of the social competence. As far as antisocial behavior concerns, no differences were found. The results obtained indicate need for redefining the role of special educators and rehabilitators in regular primary education.

Various common genetic susceptibility loci have been identified for breast cancer; however, it is unclear how they combine with lifestyle/environmental risk factors to influence risk. We undertook an international collaborative study to assess gene-environment interaction for risk of breast cancer. Data from 24 studies of the Breast Cancer Association Consortium were pooled. Using up to 34,793 invasive breast cancers and 41,099 controls, we examined whether the relative risks associated with 23 single nucleotide polymorphisms were modified by 10 established environmental risk factors (age at menarche, parity, breastfeeding, body mass index, height, oral contraceptive use, menopausal hormone therapy use, alcohol consumption, cigarette smoking, physical activity) in women of European ancestry. We used logistic regression models stratified by study and adjusted for age and performed likelihood ratio tests to assess gene–environment interactions. All statistical tests were two-sided. We replicated previously reported potential interactions between LSP1-rs3817198 and parity (Pinteraction = 2.4×10−6) and between CASP8-rs17468277 and alcohol consumption (Pinteraction = 3.1×10−4). Overall, the per-allele odds ratio (95% confidence interval) for LSP1-rs3817198 was 1.08 (1.01–1.16) in nulliparous women and ranged from 1.03 (0.96–1.10) in parous women with one birth to 1.26 (1.16–1.37) in women with at least four births. For CASP8-rs17468277, the per-allele OR was 0.91 (0.85–0.98) in those with an alcohol intake of <20 g/day and 1.45 (1.14–1.85) in those who drank ≥20 g/day. Additionally, interaction was found between 1p11.2-rs11249433 and ever being parous (Pinteraction = 5.3×10−5), with a per-allele OR of 1.14 (1.11–1.17) in parous women and 0.98 (0.92–1.05) in nulliparous women. These data provide first strong evidence that the risk of breast cancer associated with some common genetic variants may vary with environmental risk factors.

Abstract The purpose of this study is to analyze the factors influencing wine consumption of Generation Y consumers in the context of two countries from South-Eastern Europe (Bosnia -Herzegovina, and Croatia). Analysis reveals that self-expression, sociability, tradition and food are significant predictors of wine consumption. Multivariate regressions have been applied in order to explain the influences of the abovementioned factors on wine consumption. Research findings show that specific gender and situational differences exist in the wine consumption behaviour of Generation Y. This paper discusses theoretical, empirical and practical implications, and offers ideas for further research

Eutrophication, a major problem in many fresh and brackish waters, is largely caused by nonpoint-source pollution by P from agricultural soils. This lysimeter study examined the influence of P content, physical properties, and sorption characteristics in topsoil and subsoil on P leaching measured during 21 mo in 1-m-long, undisturbed soil columns of two clay and two sandy soils. Total P losses during the period varied between 0.65 and 7.40 kg ha. Dissolved reactive P was the dominant form in leachate from the sandy soils and one clay soil, varying from 48 to 76%. Particulate P dominated in leachate from the other clay soil, where low pH (5.2) in the subsoil decreased aggregate stability and thereby probably increased the dispersion of clay particles. Phosphorus leaching was small from soils with high P sorption index (PSI) and low P saturation (<10% of PSI) in the subsoil, even though extractable P (Olsen P) in the topsoil was high, and large from a soil with low sorption capacity and high P saturation (>35% of PSI) in the profile. High sorption capacity in the subsoil was more important for P leaching in sandy soils than in clay soils with macropore flow, where the effect of high sorption capacity was reduced due to less interaction between percolating water and the soil matrix. The results suggest that P leaching is greatly affected by subsoil properties and that topsoil studies, which dominate current research, are insufficient for assessing P leaching in many soils.
