The Analysis of College Students Knowledge, Attitudes. Behaviors, and Perceptions Concerning Sexually Transmitted Infections

The purpose of this study was to further research, more in-depth, college student\u27s attitudes, knowledge, and behaviors concerning sexually transmitted infections and unsafe sexual practices using the Health Belief Model as a framework. By utilizing an electronic survey and social media a non-probability convenience sample of 167 students was assessed. This study was given to undergraduate and graduate students at a midwestern college campus and was intended to evaluate college student\u27s knowledge, attitudes, behaviors, and perceptions concerning sexually transmitted infections. Two major findings were that less than half of the participants were tested for STI\u27s yearly; and there was no relationship between gender and concern of contracting an STI. To improve the state of college students concerning sexually transmitted infections, colleges need to make aware health clinics in the area that offer testing and create college courses that educate students about sexually transmitted infections

Specifying the saturation temperature for the HyspIRI 4-μm channel

The investigation of high-temperature natural phenomena, such as wildland fires and active lava flows, is a primary science objective for the proposed Hyperspectral Infrared Imager (HyspIRI) mission. Current planning for HyspIRI includes a mid-infrared (MIR) channel centered at 4 μm that will allow measurement of radiance emitted from high-temperature targets. In this paper we present the results of a study to specify the saturation temperature for the MIR channel. This study was based on reviews of the literature, together with case studies of airborne and satellite-based data acquired over high-temperature targets. The spatial resolution of MIR radiance measurements is an important consideration in the remote sensing of high-temperature phenomena, due to the presence of materials at different temperatures within the area covered by an image pixel. The HyspIRI MIR channel will provide a spatial resolution of 60. m, which is ~ 40 times finer (in terms of area) than the finest spatial resolution provided by heritage instruments (370m). This fine spatial resolution will increase the probability that high-temperature targets fill an image pixel and, therefore, the HyspIRI MIR channel will require a saturation temperature 2 to 4 times higher than the saturation limits of heritage instruments. Based on our study, we recommend a saturation temperature of 1200 K (927°C). This recommendation accounts for the high temperatures expected for natural phenomena, expected performance of the MIR channel, and overlap in sensitivity between the MIR and thermal infrared (7.5-12μm) HyspIRI channels.</p
