The University of Texas of the Permian Basin is located in Odessa, Texas. It was authorized by the Texas Legislature in 1969 and founded in 1973. Its official fall 2010 enrollment was 4,063 and projected fall 2013 enrollment is 5,073. The university faces rapid growth as a result of the oil-boom currently ongoing in the Permian Basin.

Objective: Using CARES data, to develop a composite multivariate logistic regression model of survival for projecting survival rates for out-of-hospital arrests of presumed cardiac etiology (OHCA). Methods: This is an analysis of 25,975 OHCA cases (from October 1, 2005 to December 31, 2011) occurring before EMS/first responder arrival and involving attempted resuscitation by responders from 125 EMS agencies. Results: The survival-at-hospital discharge rate was 9% for all cases, 16% for bystander-witnessed cases, 4% for unwitnessed cases, and 32% for bystander-witnessed pVT/VF cases. The model was estimated separately for each set of cases above. Generally, our first equation showed that joint presence of a presenting rhythm of pVT/VF and return of spontaneous circulation in the pre-hospital setting (PREHOSPROSC) is a substantial direct predictor of patient survival (e.g., 55% of such cases survived). Bystander AED use, and, for witnessed cases, bystander CPR and response time are significant but less sizable direct predictors of survival. Our second equation shows that these variables make an additional, indirect contribution to survival by affecting the probability of joint presence of pVT/VF and PREHOSPROSC. The model yields survival rate projections for various improvement scenarios; for example, if all cases had involved bystander AED use (vs. 4% currently), the survival rate would have increased to 14%. Approximately one-half of projected increases come from indirect effects that would have been missed by the conventional single-equation approach. Conclusion: The composite model describes major connections among predictors of survival, and yields specific projections for consideration when allocating scarce resources to impact OHCA survival. © 2013 Elsevier Ireland Ltd.

Cam follower systems are widely used in manufacturing because of their precise motion and ability to easily dwell. The cam typically drives a follower in some precise motion needed to accomplish a manufacturing task. Presented in this paper is a closed-form modified trapezoidal cam motion function with adjustable positive and negative acceleration. The profile is suitable for multiple-dwell cam and follower applications. The profile is particularly applicable to high-speed cams in which the follower acceleration is a primary design objective. The main benefit of the profile is that it allows cam designers to easily set limits on the positive and negative acceleration to achieve design objectives. Additional benefits are that the cycle jerk is continuous and that the cam designer can control the maximum magnitude of jerk. The motion program is presented in closed-form for easy implementation in standard equation-solver or spreadsheet software. Dynamic and harmonic analyses are presented to illustrate the benefits of the profile. © 2012 American Society of Mechanical Engineers. Source

Average stature is now a well-accepted measure of material and economic well-being in development studies when traditional measures are sparse or unreliable, but little work has been done on the biological conditions for individuals on the nineteenth-century U.S. Great Plains. Records of 14,427 inmates from the Nebraska state prison are used to examine the relationship between stature and economic conditions. Statures of both black and white prisoners in Nebraska increased through time, indicating that biological conditions improved as Nebraska’s output market and agricultural sectors developed. The effect of rural environments on stature is illustrated by the fact that farm laborers were taller than common laborers. Urbanization and industrialization had significant impacts on stature, and proximity to trade routes and waterways was inversely related to stature. © 2015, Springer Science+Business Media New York.

The Early Childhood Longitudinal Study-Birth Cohort of 2001 represents a unique opportunity to examine the life situations of teenage mothers and their young children in a nationally representative sample. Descriptive and multivariate regression analyses compare teenage mothers and their children to older mothers and their children, examine variation among teenage mothers and their children, and estimate associations between household structures and mothers' work and school involvement at age 2 and children's health and development at age 41/2. Results show that compared to children of mothers who never gave birth as teens, teenage mothers' children experience strong socioeconomic disadvantages, and their home environments have some greater risks. Their mothers' parenting behaviors are not rated as favorably, and many measures of their health and development at age 2 are compromised. However, many of these parenting and developmental disparities are explained by teenage mothers' low levels of current socioeconomic status. At least in some domains, teenage mothers' involvement in school and paid work is associated with more favorable child outcomes at age 41/2, and living with a single mother and other adults predicts more negative outcomes. Many everyday experiences that are associated with disadvantaged outcomes are quite prevalent among teenage mothers' children, identifying useful targets for policy interventions. These findings suggest that effective social programs implemented in early life may have an opportunity to reduce the early developmental disadvantages of many children of teenage mothers. © 2011 Springer Science+Business Media B.V.

The X-ray structures of the π-complex [Pt(PNP)(CH 2=CHPh)] (BF 4) 2 and the σ-complex [Pt(PNP)((E)-CH=CHPh)] BF 4 are reported (PNP = 2,6-bis(diphenylphosphinomethyl)pyridine). The styrene complex undergoes vinylic deprotonation by reaction with the weakly basic nucleophiles ROH (R = Me, Et, H), which was monitored by 1H and 31P NMR. The mechanistic pathway includes nucleophilic addition of the oxygen donor nucleophiles to the coordinated styrene. The resulting addition products [Pt(PNP)(CH 2CHPhOR)]BF 4 transformed to the styryl complex only when protons are present. Similarly, the related 1-vinylnaphthalene complex [Pt(PNP)(CH 2=CHC 10H 7)](BF 4) 2 undergoes vinylic deprotonation in the presence of methanol, forming the corresponding σ-complex [Pt(PNP)((E)-CH=CHC 10H 7)]BF 4. © 2010 American Chemical Society.
