This two-wave longitudinal study examined risky sexual scripts and sexual behavior regarding consensual sexual interactions, sexual self-esteem, initiation assertiveness, and religiosity as predictors of sexual aggression perpetration in a cross-cultural comparison of college students in Chile and Turkey. As predicted, risky sexual scripts were linked to higher odds of perpetration through more risky sexual behavior cross-sectionally in both the Chilean and the Turkish sample and indirectly predicted perpetration 12 months later. High sexual self-esteem increased the likelihood of perpetration via higher initiation assertiveness in the Turkish sample only. High religiosity reduced the odds of perpetration through less risky sexual scripts and less risky sexual behavior in both samples. In addition, high religiosity increased the probability of perpetration through lower sexual self-esteem in the Turkish sample. Implications of these findings and the role of cultural factors contributing to the differential functioning of religiosity and sexual self-esteem are discussed.
Sexual aggression is a major public health issue worldwide, but most knowledge is derived from studies conducted in North America and Western Europe. Little research has been conducted on the prevalence of sexual aggression in developing countries, including Chile. This article presents the first systematic review of the evidence on the prevalence of sexual aggression victimization and perpetration among women and men in Chile. Furthermore, it reports differences in prevalence rates in relation to victim and perpetrator characteristics and victim–perpetrator relationships. A total of N = 28 studies were identified by a three-stage literature search, including the screening of academic databases, publications of Chilean institutions, and reference lists. A great heterogeneity was found for prevalence rates of sexual victimization, ranging between 1.0% and 51.9% for women and 0.4% and 48.0% for men. Only four studies provided perpetration rates, which varied between 0.8% and 26.8% for men and 0.0% and 16.5% for women. No consistent evidence emerged for differences in victimization rates in relation to victims’ gender, age, and education. Perpetrators were more likely to be persons known to the victim. Conceptual and methodological differences between the studies are discussed as reasons for the great variability in prevalence rates, and recommendations are provided for a more harmonized and gender-inclusive approach for future research on sexual aggression in Chile.
We address the question of whether all large-magnitude earthquakes produce an erosion peak in the subaerial components of fluvial catchments. We evaluate the sediment flux response to the Maule earthquake in the Chilean Andes (Mw 8.8) using daily suspended sediment records from 31 river gauges. The catchments cover drainage areas of 350 to around 10,000 km(2), including a wide range of topographic slopes and vegetation cover of the Andean western flank. We compare the 3- to 8-year postseismic record of sediment flux to each of the following preseismic periods: (1) all preseismic data, (2) a 3-year period prior to the seismic event, and (3) the driest preseismic periods, as drought conditions prevailed in the postseismic period. Following the earthquake, no increases in suspended sediment flux were observed for moderate to high percentiles of the streamflow distribution (mean, median, and >= 75th percentile). However, more than half of the examined stations showed increased sediment flux during baseflow. By using a Random Forest approach, we evaluate the contributions of seismic intensities, peak ground accelerations, co-seismic landslides, hydroclimatic conditions, topography, lithology, and land cover to explain the observed changes in suspended sediment concentration and fluxes. We find that the best predictors are hillslope gradient, low-vegetation cover, and changes in streamflow discharge. This finding suggests a combined first-order control of topography, land cover, and hydrology on the catchment-wide erosion response. We infer a reduced sediment connectivity due to the postseismic drought, which increased the residence time of sediment detached and remobilized following the Maule earthquake.
