The family is one of the key factors that can contribute to reducing the negative consequences of high-risk sexual behavior. This study examines the influence of parents’ communication with children on issues of sexuality on sexual behavior.

The study is based on a mixed research design. In 2013-2014, 1,359 people aged 18-30 years were randomly selected from urban areas covering the main university centers of Romania, and they completed a questionnaire with 60 items regarding sociodemographic data, family, sexual behavior and health risks. Out of the initial sample, 60 participants agreed to participate in face-to-face interviews, using a thematic interview guide. The quantitative data were analyzed using descriptive inferential statistics, including binary logistic regression. The qualitative data were investigated using thematic analysis.

Exploring the issues of sexual and reproductive health (SRH) discussed with parents according to gender revealed that there was a greater concern in families to address issues of sexuality with girls. The manifestation of any form of sex education in the family was positively associated with a healthy sexual debut, both for women and men (χ2 = 7.759, χ2 = 7.866, p = 0.005). The results of the regression reinforced the idea that a lack of sex education in the family decreased the likelihood of a healthy sexual debut, both in women (OR: 0.668, p = 0.018) and in men (OR: 0.605, p = 0.013). In men, receiving information about sex at a younger age (OR: 0.335, p = 0.001) reduced the chance of a healthy sexual debut. Younger women and men were more likely than older women and men to experience a healthy sexual debut [odds ratio (OR): 1.861, p < 0.001 and OR: 1.644, p = 0.015, respectively]. Qualitative results revealed that SRH talks were generally initiated by young people, usually involved a parent of the same gender and often occurred after events in the sexual lives of young people (after first menstruation/after sexual debut). Conclusions In designing health programs for adolescents and youth, the family should be involved in sex education. Modeling family sex education by gender can produce differentiated effects on the sexual debut of men and women.

Zirconia particles are generated into a nitrile rubber (NBR) matrix via a solution sol-gel method in a controlled manner. Formation of zirconia particles from their precursor (zirconium(IV) propoxide) occurs under optimized reaction conditions. As a result, the nanoparticles are embedded and well dispersed in the NBR matrix that results in a remarkable improvement in mechanical and thermal properties of the composite. Such reinforcement is not realized when the composites are prepared following the conventional technique of filler loading by physical mixing, although the filler content remains the same. Use of a surface active coupling agent TESPT (bis-(3-triethoxysilylpropyl) tetrasulfide) in the reactive sol-gel system is found to further boost the mechanical performance of the composites. In order to ensure the practical application of the developed composites, a series of studies have been performed that consist of dynamic performance, swelling, thermal degradation, and resistance to oil, ozone, and abrasion. Analysis of the results reveals that in situ zirconia could be an excellent filler for the NBR composites to withstand in a harsh and adverse environment

Using data from the first round of the national Gender and Generations Surveys of Russia, Romania, and Bulgaria, and from a similar survey of Hungary, which were all collected in recent years, we study rates of entry into marital and non-marital unions. We have used elements from the narrative of the Second Demographic Transition (SDT) as a vehicle to give our analysis of the data from the four countries some coherence, and find what can be traces of the SDT in these countries. The details vary by country; in particular, latter-day developments in union formation patterns did not start at the same time in all the countries, but in our assessment it began everywhere before communism fell, that is, before the societal transition to a market economy got underway in 1990.
