Obesity Prevalence, Weight-Related Beliefs and Behaviors among Low-Income Ethnically Diverse National Job Corps Students
The obesity rates of Job Corps students, a predominantly ethnic minority and low income group of youth, are unknown. The purpose of this project was to examine obesity rates among these youth as well as their weight-related perceptions and behavior. First, medical charts (N=641) of all Job Corps students (ages 16-25) who were enrolled in the program in the past year were examined for height and weight. In the second phase of the study, 344 Job Corp students were recruited and information on weight perceptions, knowledge of obesity consequences, and weight loss behavior were examined. Almost half of the participants were overweight or obese. Overweight males were less likely to perceive themselves as being overweight than females. The majority of participants were aware of obesity-related health consequences but of those with past weight loss attempts, only 13% reported using both exercise and diet. High levels of overweight and obesity among Job Corps students are likely to impact employment and career goals. Evidence-based obesity interventions for Job Corps students are needed
High molecular weight first generation PMR polyimides for 343 C applications
The effect of molecular weight on 343 C thermo-oxidative stability (TOS), mechanical properties, and processability, of the first generation PMR polyimides was studied. Graphite fiber reinforced PMR-15, PMR-30, PMR-50, and PMR-75 composites (corresponding to formulated molecular weights of 1500, 3000, 5000, and 7500, respectively) were fabricated using a simulated autoclave process. The data reveals that while alternate autoclave cure schedules are required for the high molecular weight resins, low void laminates can be fabricated which have significantly improved TOS over PMR-15, with only a small sacrifice in mechanical properties
Explaining the Labor Force Participation of Women 20-24
Between about the mid 1960s and the late 1970s there was a remarkable rise in the labor force participation of women and then a leveling off that has persisted through the mid 1990s. This paper attempts to explain the labor force participation of women 20-24 over this period. A "relative income" variable is constructed based on Easterlin's (1980) relative income hypothesis, and this is found to be an important explanatory variable. Easterlin's "cohort wage" hypothesis is also used in the analysis. The basic equation estimated does very well in various tests that were performed on it, and it appears to explain well the rapid rise and then leveling off of the labor force participation of young women.
Civic Engagement and Service Learning Partnerships
Service learning is designed to promote volunteerism and civic awareness. Community engagement in higher education specifically involves university members partnering with local community organizations to address a need. Students engage with community partners through service learning and other activities (Moore & Mendez, 2014). Service learning is a practice that connects new knowledge and social responsibility through active learning (Benson & Younkin, 1996).https://digitalscholarship.unlv.edu/btp_expo/1083/thumbnail.jp
Vinyl capped addition polyimides
Polyimide resins (PMR) are generally useful where high strength and temperature capabilities are required (at temperatures up to about 700 F). Polyimide resins are particularly useful in applications such as jet engine compressor components, for example, blades, vanes, air seals, air splitters, and engine casing parts. Aromatic vinyl capped addition polyimides are obtained by reacting a diamine, an ester of tetracarboxylic acid, and an aromatic vinyl compound. Low void materials with improved oxidative stability when exposed to 700 F air may be fabricated as fiber reinforced high molecular weight capped polyimide composites. The aromatic vinyl capped polyimides are provided with a more aromatic nature and are more thermally stable than highly aliphatic, norbornenyl-type end-capped polyimides employed in PMR resins. The substitution of aromatic vinyl end-caps for norbornenyl end-caps in addition polyimides results in polymers with improved oxidative stability
Anti-lecture Hall Compositions and Overpartitions
We show that the number of anti-lecture hall compositions of n with the first
entry not exceeding k-2 equals the number of overpartitions of n with
non-overlined parts not congruent to modulo k. This identity can be
considered as a refined version of the anti-lecture hall theorem of Corteel and
Savage. To prove this result, we find two Rogers-Ramanujan type identities for
overpartition which are analogous to the Rogers-Ramanjan type identities due to
Andrews. When k is odd, we give an alternative proof by using a generalized
Rogers-Ramanujan identity due to Andrews, a bijection of Corteel and Savage and
a refined version of a bijection also due to Corteel and Savage.Comment: 16 page
Archeological Testing of 41BO185 A Possible Civil War Era Military Camp, West Columbia, Brazoria County, Texas
In November and December 1999, staff from the TxDOT Archeological Studies Program conducted archeological investigations on a portion of site 41BO 185, a reported possible Civil War-era military encampment, within the boundaries of a proposed widening project on SH 35 in Brazoria County. The archeological investigations consisted of a combination backhoe trenching and hand-dug test units excavated across the portion of the site within the project area to locate and identify features and artifact concentrations. The goal of the testing was to determine the integrity of the portion of the site within the Area of Potential Effect (APE) and to determine whether this portion of the site is eligible for inclusion on the National Register of Historic Places (NRHP).
The archeological investigations identified a cistern, a brick scatter that may represent the remains of a collapsed chimney, a fireplace base, post molds, and various artifacts. The features appeared to represent a structure or structures that date to about the period of the Civil War. However, they are more likely related to a domestic structure, rather than a military camp site. The most likely civil war related artifact found during the fieldwork was a fragment of a bayonet. However, no definitive archeological evidence that a Civil War camp site was at this location was found during fieldwork. It is possible that ground disturbing activity, such as sod harvesting, may have erased any trace of the site.
Based on the results of this investigation, the portion of 41BO185 located within the project boundaries will not contribute to the potential NRHP eligibility of the site. No further archeological work is recommended for the portion of the site within the present SH 35 project area
