    The current study evaluated an intervention program, designed by the authors and based on the theory of sexual scripts and social learning theory, to reduce empirically established risk and vulnerability factors of sexual aggression. A sample of 1,181 university students in Germany (762 female) were randomly assigned to an intervention and a no-intervention control group. The intervention group completed six modules addressing established antecedents of sexual aggression perpetration and victimization: risky sexual scripts, risky sexual behavior, low sexual self-esteem, low sexual assertiveness, acceptance of sexual coercion, and perceived realism of pornography. After baseline (T1), intervention effects were measured one week after the last module (T2), nine months later (T3), and another 12 months later (T4). The intervention group showed significantly less risky sexual scripts and higher sexual self-esteem at T2, T3, and T4. The intervention indirectly reduced risky sexual behavior at T3 and T4 via less risky sexual scripts at T2 and increased sexual assertiveness at T3 and T4 via higher sexual self-esteem at T2. No intervention effects were found on the acceptance of sexual coercion and pornography realism. The implications of the findings for reducing the prevalence of sexual aggression perpetration and victimization are discussed

    Exposure to pornographic material has been linked to sexual aggression perpetration and victimization in a large body of research. Based on social learning theory and 3A theory of script learning, this study contributes to this research by testing the hypothesis that the more realistic pornography is perceived to be by young adults, the more likely they are to experience and engage in sexual aggression. Two underlying pathways were proposed: one path via scripts and patterns of sexual behavior regarding consensual sexual interactions that contain established risk factors for sexual aggression victimization and perpetration, and a second path via the acceptance of sexual coercion. In a cross-sectional study, 1181 university students in Germany (762 female; 419 male) completed measures of pornography use and perception, risky sexual scripts and sexual behavior, and acceptance of sexual coercion. As predicted, pornography realism was a positive predictor of risky sexual scripts, risky sexual behavior, and acceptance of sexual coercion. Indirect links with sexual aggression victimization and perpetration were found via both pathways. No gender differences in the associations were found. The implications for media literacy interventions addressing the realism of pornography are discusse

    Young Adults’ Understanding of Sexual Competence: A Qualitative Study with German University Students

    Get PDF
    Introduction Handling sexual interactions in a competent manner is a key skill for young adults, which is linked to positive aspects of sexual and general well-being. Several research conceptualizations of sexual competence have been proposed in the literature, but little is known about how young adults define sexual competence and what consequences they consider low sexual competence may have. Methods In this qualitative study conducted in 2019, 571 university students (365 women, 206 men) from Germany with a mean age of 22.6 years provided open-ended answers to two questions: (Q1) What do you consider to be sexual competence? (Q2) What consequences can low sexual competence have? Combining thematic analysis and qualitative content analysis, responses were coded into 264 categories that were then condensed into 30 latent themes, with 14 themes referring to Q1 and 16 themes referring to Q2. All categories showed strong inter-coder agreement. Result Participants defined sexual competence in a multi-faceted way and in partial overlap with research definitions. Gender differences emerged in four themes (needs/desires, communication, skills/abilities, and setting boundaries/limits). Participants’ statements about the consequences of low sexual competence corresponded closely with their definitions of sexual competence. Gender differences emerged in five themes (risk of sexual victimization and sexual aggression, problems in sexual communication, problematic [sexual] risk behavior, negative influence on [sexual] satisfaction, and lack of skills). Conclusions and Policy Implications The implications of the findings for research conceptualizations of sexual competence, for designing interventions to promote sexual competence, and for policy measures designed to reduce sexual aggression are discussed

    Groundwater circulation in the Miechów Trough and the central part of the Carpathian Foredeep (Poland): a hydrogeological conceptual model

    Get PDF
    The Miechów Trough and the central part of the Carpathian Foredeep in southern Poland have a highly complex geo- logical structure and numerous fault zones. These features play a significant role in hydrogeological conditions of the area. In this area drinking water, medicinal groundwater or thermal groundwater occur, so recognition of their circu- lations is basic for reasonable groundwater management. In this note, a hydrogeological conceptual model, created for the purpose of regional scale mathematical modelling, is presented. This conceptual model illustrates the geology of the hydrogeological system modelled, as well as hydrogeological conditions and characteristics of groundwater circu- lation, as determined by tectonics. Typical of the research area is the wide diversity of geological and hydrogeological conditions. The Busko-Zdrój area, a region with a long history of exploitation of medicinal groundwater, presents the best example

    Numerical modelling in research on geothermal systems

    Nowadays, numerical modelling is a common tool for support research of geothermal systems. This is possible because of development of computer sciences and access to software dedicated to numerical modelling of hydrogeological processes. With computer applications researches can do scheme of hydrogeological conditions and simulate work of geothermal systems and thermal water intakes. Researches create numerical models of geothermal systems in regional and local scale, for simulating work of specific thermal water formation and intakes and their particular elements - well active zone for example.In parallel with the economic development of the use of thermal water in Poland there are a lot of research projects where numerical modelling occurs as a primary or supporting tool. This paper provides an overview of research issues where the solution of the problem was found with using computer application and numerical simulators

    Pathways from childhood sexual abuse to sexual aggression victimization and perpetration in adolescence and young adulthood: a three-wave longitudinal study

    Get PDF
    Background: Childhood sexual abuse (CSA) has been identified as a risk factor for later sexual aggression perpetration and vulnerability factor for sexual victimization. However, the use of cross-sectional designs, the focus on female victimization and male perpetration, and the lack of evidence from outside North America limit the existing knowledge base. Objective: The study was designed to examine pathways from CSA to sexual revictimization and sexual aggression perpetration after the age of consent. Method: A total of 588 university students in Germany (308 female) took part in a three-wave longitudinal study covering 23 months. At each wave (T1–T3), all participants completed measures of sexual aggression victimization and perpetration. Experiences of CSA were measured at T1. Results: The rate of CSA was significantly higher for women (20.8%) than for men (12.4%). Rates of sexual victimization for women were 60.9% at Time 1 (since age 14), 22.3% at Time 2 (since T1), and 17.4% at Time 3 (since T2). For men, the rates were 39.2% at Time 1, 15.9% at Time 2, and 14.1% at Time 3. Rates of sexual aggression perpetration for women were 10.6% at Time 1 (since age 14), 3.5% at Time 2 (since T1), and 3.6% at Time 3 (since T2). For men, the rates were 18.0% at Time 1, 6.2% at Time 2, and 3.8% at Time 3. The gender differences in victimization and perpetration were significant only at T1. CSA predicted higher odds of sexual aggression victimization and perpetration cross-sectionally at T1 and indirectly at T2 and T3 via T1. Gender did not moderate the associations. Conclusion: The results confirm previous findings of elevated rates of sexual aggression victimization and perpetration in adolescence and young adulthood in victims of CSA. The implications for understanding and preventing adverse sexuality-related outcomes of CSA are discussed

    Prototype designs of orifice flowmeters are commonly used in measurements. One area which has attracted considerable interest includes slotted orifices, where a single central opening is replaced by the use of several slots. This paper reports the results of numerical and experimental research of a prototype design of a slotted orifice plate. The movement of the fluid was described with use of Reynolds equations closed by the k-ε turbulence model. The calculations were performed using ANSYS Fluent software package by consideration of the fluid flow through an orifice plate and slotted orifice with the equal β ratio = 0.5. The results of calculations are compared with the measurements. Good qualitative and quantitative conformity was obtained during the study for the C flow coefficient. It was indicated that the slotted orifice generates a considerable lower pressure drop in comparison to an orifice plate while maintaining comparable level of measurement uncertainty.W praktyce pomiarowej coraz częściej stosuje się prototypowe rozwiązania konstrukcyjne przepływomierzy zwężkowych. Na uwagę zasługują kryzy szczelinowe, gdzie jeden centralny otwór zastąpiony jest szczelinami. W pracy przedstawiono wyniki badań numerycznych i eksperymentalnych prototypowego rozwiązania konstrukcyjnego kryzy szczelinowej. Ruch płynu opisano równaniami Reynoldsa, domkniętymi k-ε modelem turbulencji. Obliczenia przeprowadzono przy użyciu pakietu ANSYS Fluent. Rozpatrywano przepływ płynu przez kryzę standardową i szczelinową o przewężeniu β = 0,5. Wyniki obliczeń porównano z wynikami pomiarów. Stwierdzono dobrą jakościową i ilościową zgodność wyników badań dla współczynnika przepływu C. Wykazano, że kryza szczelinowa generuje znacznie mniejszą trwałą stratę ciśnienia niż kryza standardowa przy porównywalnej niepewności pomiaru

    Unacknowledged and missed cases of sexual victimization: A comparison of responses to broad versus behaviorally specific questions

    Get PDF
    From the beginning of systematic research on sexual victimization, it has been recognized that a substantial proportion of women report nonconsensual sexual experiences meeting the defining criteria of rape in response to behaviorally specific items, but do not acknowledge their experience as rape in response to broad questions about whether they have ever been raped. Recent studies suggest that rates of unacknowledged rape may be as high or even higher among men than among women. This study examined rates of unacknowledged female and male victims of rape and sexual assault by comparing responses to behaviorally specific items of the Sexual Aggression and Victimization Scale (SAV‐S) with responses to broad questions using the labels of sexual assault and rape (SARA) in 593 participants (303 women) in Germany. As predicted, more women and men were classified as rape victims based on behaviorally specific items than on the basis of the broad rape item. The rates of unacknowledged rape were about 60% for women and 75% for men. The gender difference was not significant. Against our prediction, no significant differences in acknowledgement of sexual assault were found in relation to coercive strategy and victim–perpetrator relationship. Few cases of rape and sexual assault identified by the SARA items were missed by the behaviorally specific questions. The implications for establishing prevalence rates of rape and sexual assault and for comparing victims and nonvictims in terms of vulnerability factors and outcomes of sexual victimization are discussed

    The differential pressure of gas measurement is very often used in industrial measurements. During the gas flow, liquid condensation often occurs. The result is that when measuring a gas flow, the gas-liquid mixture is essentially measured. Errors in the indications of measuring instruments are starting to appear due to a change in the properties of the continuous phase, which is gas. In addition, the appearance of liquid droplets leads to flow disturbances and pressure pulsations. Therefore, new methods and tools for measuring the flow of gas-liquid mixture are being sought. The work involves the use of slotted orifices for measuring gas-liquid mixtures. An analysis of the influence of the slotted orifice geometry on the measurement of the biphasic mixture stream was carried out. Standard orifice and three slotted orifices of various designs. The experiment included measuring the air flow with a small amount of water dispersed in the form of drops.Pomiar gazu metodą zwężkową jest bardzo często stosowany w pomiarach przemysłowych.

    Poland has been struggling with the problem of exceedance of the permissible levels of air pollutions such as particulate matter (PM10, PM2.5) and benzo(a)pyrene (BaP) for several years. In the years 2007-2015 the concentrations of PM10 and BaP exceeded the European Union (EU) limit values. The vast majority of the country is characterised by wind energy zones described as very favorable and favorable. Facing the current legal regulations, wind micro-installations are becoming an opportunity to use the potential of wind energy in Poland. The micro-installations market in Poland is constantly growing. In 2017 there was recorded a nearly ten-fold increase in the number of micro-installations of renewable energy sources connected to the network in regard of 2015. The analysis based on available wind energy resources and available technologies of small wind turbines on the market showed that by installing a 10 kW turbine in the zone with the most favorable wind conditions (1000 kWh/m2/year) one can avoid 93kg of dust emissions to the air and 140 kg of CO and 6222 kg of CO2. The calculated reduction of dust emissions for 3 kW wind turbine in area of Rabka-Zdrój is about 0.8 kg, in the case of BaP 0.0003 kg, and for CO2 47.3 kg
