The purpose of the study was to develop a scale to measure sexual orientation and to examine its psychometric properties. Previous scales were critically examined and compared and the need for a scale which simultaneously measures same and opposite sex responsiveness independently, and accounts for dynamic changes over time, while testing a number of overt and covert dimensions of sexual orientations, was established. A 48-item scale was designed to tap self-reported intensity and frequency of Emotional Attachment, Sexual Fantasy, Sexual Attraction and Sexual Contact towards males and females in the Past, Present and Future. An initial study was conducted with 13 undergraduate university students of both genders, representing a variety of sexual orientations and nationalities, and qualitative feedback was obtained and utilized to make appropriate adjustments and refinements to the scale. The scale was then administered to 133 Rhodes University undergraduate psychology students to obtain quantitative data with regard to its internal structure. The scale was found to have a good internal consistency reliability Cronbach alpha coefficient of 0.8106. Existing sub-scales had lower alpha coefficients. Factor analysis, a form of construct validation, was performed and four factors emerged. These had very good internal consistency reliability alpha coefficients: Sexual Responsiveness to Females (0.9894), Sexual Responsiveness to Males (0.9741), Emotional Attachment to Females (0.8403) and Emotional Attachment to Males (0.8372). These factors were further statistically analysed to ascertain how they relate to one another and to the demographics of gender, age, relational status and sexual orientation identity. Future research will need to assess other forms of reliability and validity and focus on larger and more varied samples.

This study aimed to use data and rainfall characteristics such as density of precipitation, slope and direction of rainfall, as topographical features, inclination and orientation of the aspects to simulate the kinetic energy of rain on the slopes and the attenuating effect of the vegetation cover in reducing these kinetic effects. Were used rainfall data measured in the UFG weather station for this, together with data from rain gauges vector, collected during the years 2012 and 2013, trying to simulate the effects on and off-season crop, using classes of land use in the catchment area of the river Paraíso. The results showed that the rain gauge PVC 163 cm ² is compatible with standard rain gauge INMET, whose data were used for this study. Analysis of the results showed that most of the rainfall comes from southeast, followed by coming rains from the south. The slope and orientation of the aspects of the terrain within the basin favored the simulation in a view to highlighting these impacts. The highest rainfall was in February 2012 (244.3 mm) and January 2013 (252.6 mm), the largest attenuation of impacts occurred during the months of April 2012 and January 2013, mainly on the slopes contrary direction predominant rains and approximate slope to the inclination of the rains. It was also observed that the attenuating effect of ground cover showed accented results regarding coverage and growing season and this takes to the conclusion that the simulation reached adopted relevant results once it became clear where the largest reductions occur. / As simulações dos impactos cinéticos da chuva sobre uma bacia hidrográfica são importantes para planejamento agronômico, ambiental e regional. Este trabalho teve como objetivo utilizar dados e propriedades pluviométricas como: densidade das precipitações, direção e inclinação das chuvas, aspectos topográficos como, declividade e orientação das vertentes, para simular a energia cinética das chuvas sobre as encostas e o efeito atenuante da cobertura vegetal na redução destes impactos cinéticos. Para isso foram utilizados dados pluviométricos medidos na estação meteorológica da UFG, juntamente com dados de pluviômetros vetoriais, coletados durante os anos de 2012 e 2013, procurando simular os efeitos na safrinha e safra, utilizando as classes de uso do solo na bacia hidrográfica do ribeirão Paraíso. Os resultados mostraram que o pluviômetro de PVC de 163 cm² é compatível com o pluviômetro padrão do INMET, cujos dados foram utilizados para o presente estudo. As análises dos resultados mostraram que a maioria das chuvas vem de sudeste, seguida por chuvas vindas do sul. A declividade e orientação das vertentes dentro da bacia favoreceram a simulação no sentido de evidenciar esses impactos. As maiores precipitações foram em fevereiro de 2012 (244,3 mm) e janeiro de 2013 (252,6 mm), as maiores atenuações de impactos ocorreram durante os meses de abril de 2012 e janeiro de 2013, principalmente sobre as vertentes contrárias a direção predominante das chuvas e com declividade aproximada à da inclinação das chuvas. Foi observado também que o efeito atenuante da cobertura do solo mostrou resultados acentuados em relação à cobertura e época de cultivo e isso leva a concluir que a simulação adotada chegou a resultados relevantes uma vez que foi possível evidenciar onde ocorrem as maiores reduções.
