Squamous cell carcinoma of the dorsal hands and feet after repeated exposure to ultraviolet nail lamps
Gel nails are a common artificial nail option. Ultraviolet (UV) nail lamps are commonly used to cure gel nails. Ultraviolet A radiation is a known mutagen that penetrates into the nail bed. Although previously reported, the role of UV nail lamps in the carcinogenesis of both keratinocyte carcinoma and melanoma remains controversial. Herein, we report a patient taking the photosensitizing agent hydrochlorothiazide who developed numerous squamous cell carcinomas on the dorsal hands and feet with a 10-year history of UV nail light exposure every 2-3 weeks
Law Enforcement’s Social Media Punitive Anomaly
This research is a descriptive study of the misuse of social media in law enforcement from 2011 to present. The research will use a content analysis of social media policies coupled with survey of 10 questions administered anonymously to students at the Department of Criminal Justice Training. This mixed method approach will attempt to explain the growing number of police officers and other law enforcement employees who find themselves in violation of the agency policies. The survey consists of Likert scale style questions concerning the agreement with and understanding of social media policies, as well as the perception of privacy while using social media. The quantitative portion of the survey will gather data on age, education, race, gender, and agency type in an effort to see if any those variables correlate to policy violations. Since social media sites became popular in early to mid-2000’s there have been countless examples in the news of police officers and other law enforcement employees being suspended or fired because of poor choices made on social media sites. This study hopes to find a solution to this phenomenon or at the very least an explanation. While there was no statistical significance among dependent variables, there was a strong sense of privacy when using social media. The data showed that while there seemed to be an understanding of agency policy there were still a large number of violations occurring. During the content analysis the use of vague definitions and subjective standards could be the cause. Future works with this study would explore the connection between the subjective standards and the policy violations
The Social Significance Of Battle
Social historians have explored uncharted territory and recorded many previously untold stories that capture the full scope of human experience. Historical narratives now incorporate new perspectives; new subjects in history have gained prominence. However, many potential influences upon social hi...

A biomechanical investigation of female arm strength.
The purpose of the current study was to measure strength and develop regression equations that will predict the maximal capabilities for hand forces exerted in a variety of directions and positions. A biomechanical methodology was utilized to examine 29 non-skilled female subjects exerting maximal forces against a simulation device. Combinations of three heights (head height, shoulder height, waist height), three angles (0°, 45°, and 90° to sagittal shoulder plane), and two reaches (40% and 80% of full reach) were tested for maximal force in six directions (push forward, pull backward, push up, push down, medial, lateral). Using the force data, 12 regression equations were developed to predict average maximum force for the working female population. For each direction, an equation was developed for exertions ≥ shoulder height and for exertions ≤ shoulder height. These equations use inputs of various combinations of distance in the vertical, horizontal and lateral direction from the shoulder. The regression equations resulted in r2 values ranging from 86.0% (lateral) to 98.9% (medial) and RMS errors ranging from 8.0% (push down) to 3.0% (medial). With a mean r 2 of 94.6% and RMS %Error of 5.4%, the equations produced very accurate predictions. Using a correction factor of 0.808, each equation can be used to predict the maximum recommended force for 75th percentile of females. In addition to the force results, electromyography results provided information on muscle activity during the exertions in all postures. (Abstract shortened by UMI.)Dept. of Kinesiology.

Historiography And Civil War
The father of history, Herodotus, in The Histories, wrote so that human achievement may not become forgotten in time. While his intellectual successor, Thucydides, in The History of the Peloponnesian War, wrote for those who want to look into the truth of what was done in the past. T...

When are we guessing? An investigation of the impact of guessing on the validity of results in the assessment of students in large-scale assessment programs
The 21st century shift towards economic rationalism has included a trend towards measuring the outcomes of education and, equipped with these data, placing a higher priority on accountability in all sectors of the educational community. Corresponding to this shift, policy makers and government officials continue to demand better quality information on which to make data-informed decisions and allocate resources. To measure educational outcomes, for instance, stakeholders routinely look to national and international large-scale testing programs for indicators of success in achieving national goals and to identify areas for systemic attention.
A majority of these large-scale assessments use multiple-choice item types to assess student ability for the reporting of the outcomes of student achievement against curriculums and national or international standards. Students are encouraged to attempt all questions in these assessments. By doing so it is likely that students will guess the answers to those items where the concepts assessed are beyond their capabilities and be rewarded with an incremental increase in their results. This has the potential to threaten the validity of students’ overall results, due to the chance of correctly guessed responses inflating assessment results beyond students’ actual ability levels.
This PhD research investigated the potential impact of – and proposed a statistical solution for – guessing in large-scale education assessments. Specifically, it examined the outcomes from a novel application of the Rasch analysis technique, which quantified and adjusted for the measurement error associated with guessing and, consequently, increased the validity of the outcomes of the assessments
