Title IX Compliance in Virginia High Schools

Lyons, Daniel E. 17 April 2006 (has links)
More than thirty years ago Congress passed the Educational Amendments to ensure fair treatment for all students. Specifically, Title IX provided that [N]o person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any education program or activity receiving federal financial assistance (Educational Amendments of 1972,p. 7). The number of court cases against colleges and high schools for violating various aspects of Title IX continues to increase. This study looked at court cases involving high school and college athletes claiming violations of Title IX, then six schools were selected in Virginia to determine if these schools met the legal standards, as determined by the Code of Federal Regulations. An analysis of judicial opinions for cases on Title IX formed the foundation of this study. The six schools were visited, records reviewed, principals, and coaches were interviewed The information and data gathered from site visits and interviews as well as the statistical data generated by the statistical software were used to determine if these schools were in compliance with Title IX of the Educational Amendments of 1972. / Ed.

Rental Housing Search and Occupancy Experiences of Veterans with Disabilities

Semeah, Luz Mairena 12 June 2013 (has links)
The search for rental housing can be a very stressful and complex process for veterans with service-connected disabilities. This process requires the evaluation of different factors, such as one's credit score, housing costs in relation to income and employment status, space requirements, type of housing structure, quality preferences, and neighborhood preferences. The purpose of this study was to investigate and document the housing search and occupancy experiences of veterans with disabilities. The study describes the current rental housing situation of these veterans and examines their satisfaction with their current housing. The contextual framework of this study was developed based on Morris and Winter's (1975, 1978) theory of housing adjustment which identifies the key role of housing satisfaction as a measure to evaluate housing against housing norms and specialized needs. Issues associated with veterans with disabilities and their experience with accessibility, discrimination and Fair Housing Act provisions were integrated into the analysis of satisfaction. Three major hypotheses were tested. Data collection occurred employing a mixed-mode survey design via a self-administered on-line survey and interviews, between October 9, 2012 and February 2, 2013. Eighty-three surveys were collected through job fairs and veteran community sponsored events, the Virginia Wounded Warrior Program, Iraq and Afghanistan Veterans of America, and other organizations. Descriptive statistics (frequencies, percentages, and means) were used to provide profiles of the respondents, including demographic information, search process, current housing situation, accessible features, satisfaction with current housing, awareness of the FHAA, and military experience. One-way ANOVA, t-test, and Chi-Square were used to analyze associations when testing the three hypotheses. The study results demonstrate that these veterans could benefit from increased awareness of the provisions of the FHAA. Further, findings suggest there is a need to educate veterans about the value of filing formal complaints about housing discrimination in order to potentially reduce the frequency of housing discrimination behaviors against veterans with service-connected disabilities. OEF/OIF veterans with trauma-related injuries were more likely to be dissatisfied with their housing and more likely to have experienced discrimination during the housing search process. The findings from this research are useful to veterans looking for rental housing, property managers looking to attract and maintain veteran renters, and organizations looking to assist veterans with housing related issues. / Ph.

Copper adsorption/desorption characteristics on copper amended soils

Reed, Stewart T. 06 June 2008 (has links)
Laboratory tests were conducted to determine Cu availability of three Virginia soils amended with Cu as either Cu-rich pig manure or CuSO₄ with the same Cu content as that in manure. The study also assessed the capability of Mehlich-3 to estimate deficient and toxic Cu levels in soil. Application of Cu as manure or CuSO₄ did not affect grain yield or grain Cu concentration in corn grown at each site. Young corn plant height was reduced by CuSO₄ application on the Bertie sandy loam, an indication of greater toxicity from inorganic than organic Cu. Very little exchangeable or solution Cu was present in any of the three soils. The vast majority of Cu was distributed between the organic and soil oxide fractions. The ratio of soil oxide to organic matter determines the relative distribution of Cu among these fractions. Most organically bound Cu was held by specific adsorption mechanisms and Mehlich-3 strongly extracts this fraction. Mehlich-3 extraction patterns were indicative of Cu binding strength in the different soils. Since Mehlich-3 strongly extracts specifically bound Cu and only poorly removes oxide Cu, this test may underestimate Cu availability on sandy soils with low organic matter content. However, Mehlich-3 provides an acceptable test for soil Cu. Soil sorption characteristics were studied for Cu, Pb, and Zn added, both alone and simultaneously. Copper sorption energy was higher than both Pb or Zn, however, sorption capacity followed the order Pb > Zn > Cu. High Pb and Zn sorption was in part due to precipitation reactions especially at high initial solution concentrations. Zinc was bound to soil mostly by weak electrostatic forces. Copper and Pb were bound at specific sorption sites and by complex multi-site bonding mechanisms possibly involving organic substances. These specific and multi-site mechanisms account for metal ions removed from solution at low concentration. Even at low metal concentration, Cu and Pb sorption results in concurrent release of H⁺ and Ca²⁺ at a greater than one to one charge basis. Soils adjusted to various pH levels were equilibrated with Cu solution and then extracted with a series of dilute acid extractions to determine Cu adsorption and fixation capacities. Copper adsorption and more importantly Cu fixation increased with an increase in soil pH. Soil with a high organic matter content as a result of manure applications adsorbed and fixed more Cu at all pH levels than the control and CuSO₄ soil. The presence of organic matter may have a greater effect on metal sorption characteristics than maintenance of pH ≥ 6.5. Heavy metal sorption was accompanied by concurrent release of H⁺ and Ca²⁺ which represents exchangeable and specifically bound cation nutrients. Soils which receive heavy metal applications from sewage sludge or animal manure would have a short-term increase in plant available nutrients at the expense of long-term reserve capacity. Soil tests for cation nutrient availability on soils receiving heavy metal applications should be adopted to account for these responses. / Ph. D.
