N2  - The study is the first to provide data on risk factors for sexual aggression in male college students in Brazil. A total of N = 286 participants took part in the study, of whom a subsample of n = 120 participated in two measurements separated by a 6-month interval. Cognitive (i.e., risky sexual scripts, normative beliefs), behavioral (i.e., pornography use, sexual behavior patterns), and biographical (i.e., childhood abuse) risk factors were linked to sexual aggression both cross-sectionally and longitudinally, with the path models for the cross-sectional and longitudinal analyses demonstrating good fit with the data consistent with the hypotheses. The extent to which risk factors for sexual aggression (alcohol consumption, casual sex, and ambiguous communication) were included and normatively accepted in participants' cognitive scripts for consensual sex was linked to sexual aggression through risky sexual behavior. Risky sexual behavior was further predicted by childhood abuse, and pornography use was linked to sexual aggression via risky sexual scripts. The findings contribute evidence from Brazil to the international database on risk factors for sexual aggression in male college students.

T1  - Connectivity of sediment transport in a semiarid environment: a synthesis for the Upper Jaguaribe Basin, Brazil
JF  - Journal of soils and sediments : protection, risk assessment and remediation
N2  - Hydrosedimentological studies conducted in the semiarid Upper Jaguaribe Basin, Brazil, enabled the identification of the key processes controlling sediment connectivity at different spatial scales (10(0)-10(4) km(2)).
 Water and sediment fluxes were assessed from discharge, sediment concentrations and reservoir siltation measurements. Additionally, mathematical modelling (WASA-SED model) was used to quantify water and sediment transfer within the watershed.
 Rainfall erosivity in the study area was moderate (4600 MJ mm ha(-1) h(-1) year(-1)), whereas runoff depths (16-60 mm year(-1)), and therefore the sediment transport capacity, were low. Consequently, similar to 60 % of the eroded sediment was deposited along the landscape, regardless of the spatial scale. The existing high-density reservoir network (contributing area of 6 km(2) per reservoir) also limits sediment propagation, retaining up to 47 % of the sediment at the large basin scale. The sediment delivery ratio (SDR) decreased with the spatial scale; on average, 41 % of the eroded sediment was yielded from the hillslopes, while for the whole 24,600-km(2) basin, the SDR was reduced to 1 % downstream of a large reservoir (1940-hm(3) capacity).
 Hydrological behaviour in the Upper Jaguaribe Basin represents a constraint on sediment propagation; low runoff depth is the main feature breaking sediment connectivity, which limits sediment transference from the hillslopes to the drainage system. Surface reservoirs are also important barriers, but their relative importance to sediment retention increases with scale, since larger contributing areas are more suitable for the construction of dams due to higher hydrological potential.
