The Tarantula Atypus Milberti in Michigan (Araneae: Atypidae)

Excerpt: The arachnid genus Atypus (family Atypidae, suborder Mygalomorphae) contains four species in North America. These tarantulas are atypical because they have retained remnants of the primitive segmentation characteristic of Mesozoic spiders; the dorsum of the abdomen has tergites which differ little or not at all from those found on Oligocene spiders in the Florissant shales or in Baltic amber. The atypical tarantulas are among the most generalized of all living spiders, lacking the specialized morphological features of more advanced families. They lack reduction, migration, or enlargement of eyes; they have simple dry silk glands only; their legs lack specialization for running or silk handling; the carapace is unspecialized. This genus seems to remain successful in interspecific competition, not because of morphological specialization, but due to behavioral uniqueness. The spider constructs a vertical tube web from an underground burrow up the trunk of a tree. The web acts as a shield, making the spider unrecognizable as a potential predator. The prey is attacked through the silk, pulled inside the tube, and sucked dry. Afterwards the carcass is thrown out and the tube is repaired

How Well Are Your Police Doing?: The Relationship Between Fear of Crime and Perceptions of the Police

Research on the fear of crime, or the fear of victimization, started becoming a popular topic in the late 1960s and has stayed in the spotlight since then. However, there has been a very small amount of literature that has focused on how an individual\u27s fear of crime impacts their perceptions of the police. There has also been cloudiness in previous literature about how to measure fear of crime. This study examines the relationship between an individual\u27s fear of crime and their perceptions of the police using two different measures of police, perceptions of police effectiveness and perceptions of community policing. Additionally, this study compared two different measurements of fear of crime, a general measure and a specific measure, to determine which is a better predictor of perceptions of police. The data for this study are obtained from the 2008-2009 survey Developing Uniform Performance Measures for Policing in the United States: A Pilot Project in Four Agencies. Results showed that the better predictor of perceptions of police depended on which aspect of police is being measured. Additionally, results showed that as an individual\u27s fear of crime increases, their perceptions of the police become more negative. The results of this study will be useful to police departments, government agencies and communities around the country

Family-Friendly Science: Increasing Family Engagement in STEM Education

Family engagement is vital to a child’s success in his or her academic career. Current research has focused more specifically on the relationship between parent engagement in science, technology, engineering and math (STEM) education and a student’s success in his or her STEM education. This paper is a summary of present research pertaining to this topic, as well as a summary of the results of a field-based study the author and faculty mentors completed to learn more about methods for engaging families in STEM education, particularly in the area of science. Present research indicates that a successful method for engaging families in education is to provide families with meaningful, home-based activities to complete collaboratively. In order to test the effectiveness of such a method, the student researcher placed it into practice at the 2016 STEM in the Park event on Bowling Green State University’s campus. Activities were distributed to families following an initial survey of their current STEM educational practices and attitudes. Results of this survey are described in this submission, along with the summary of present research

Single- and Dual-Energy CT: A Comparison

This research offers a comparison of two types of computed tomography (CT) configurations by exploring each scanner type and the accompanying image specifications, protocols, radiation doses, geometric aspects, and photographic aspects of the resulting images. The comparison aimed to determine if single-energy CT (SECT) or dual-energy CT (DECT) had any clear advantages over the other scanner type. Several studies in the research resulted in DECT displaying a decrease in dose without compromising contrast-to-noise ratio (CNR). The studies in this research also showed DECT had a superior ability of decreasing iodine by 70% concentration dose while obtaining the same image quality as SECT at normal iodine dose. This research provides the reasoning that DECT is highly sought after for its abilities of dose reduction, metal reduction, improved iodine quantification, spectral separation, and temporal resolution. While DECT is far more expensive in a department than SECT, the research implicates it is more desirable for patients with prostheses, poor renal function, pediatrics, low dose lung studies, and any patient in need of a cardiac study. Further research should be performed on DECT due to its newness in the field of CT and more advancements that could additionally benefit patients and the technologists who utilize it.

Effects of hypnotic drugs on performance before and after sleep

The effects of various hypnotics on sleep stage parameters and on the parameters of effectiveness were evaluated along with the effects of several commonly used yet distinctly different hypnotics on daytime performance. The effects on daytime performance of two nonhypnotics commonly used in the space program were also examined
