Effect Of Staged Practices And Motivational Climate On Goal Orientation And Sportsmanship In Community Youth Sport Experiences, Mary Sara Wells, Gary D. Ellis, Skye G. Arthur-Banning, Mark F. Roark

Kinesiology and Health Science Faculty Publications

Significant acts of poor sportsmanship and aggression are becoming increasingly prevalent in youth sports. Youth who have negative experiences as a result of witnessing or being directly involved in such poor sportsmanship experiences are less likely to participate in future sport activities, thereby contributing to sedentary lifestyles and a number of health related problems. Goal orientation theory provides a basis for understanding why many of these unsporting acts may occur. “Task-oriented” participants focus on their intra-individual growth and development in sports and tend to be much less involved in aggression and poor sportsmanship. In contrast, “Egooriented” participants judge success in …

The Influence Of Low Humidity, Pseudacteon Flies, And Competition By Solenopsis Xyloni On Solenopsis Invicta, Ricardo A. Ramirez, D C. Thompson, M D. Remmenga

Biology Faculty Publications

Red imported fire ant, Solenopsis invicta Buren, is a serious pest in the southeastern United States. It has caused economic losses in agricultural products, stings can cause anaphylactic shock, and it has reduced biodiversity. S. invicta has displaced native ant species throughout its range, presumably by competitive exclusion. In 1998, S. invicta populations were confirmed in southern New Mexico, resulting in a quarantine of Doña Ana County. Although large populations of the native southern fire ant, S. xyloniMcCook, are common in the Mesilla Valley, only two small populations of S. invicta have been found since the initial quarantine. It is …

Polymorphism And Growth Behavior Of Low-Trans Fatty Acids Blends Formulated With And Without Emulsifiers, Marina Cerdeira, Silvana Martini, Roberto J. Candal, Maria L. Herrera

Nutrition, Dietetics, and Food Sciences Faculty Publications

Polymorphism and growth behavior of blends of a high-melting fraction of milk fat (HMF) and sunflower oil (SFO) formulated with and without the addition of sucrose esters (SE) P-170, P-1670, and S-170 were studied by pulsed 1H NMR spectroscopy, X-ray diffraction, and polarized light microscopy. The effect of SE on the solid content maximum (S max) or crystallization rate was observed only at low supercooling (values of ΔT below 15°C). The Avrami k n decreased as n values increased, indicating that SE inhibited growth and impeded nucleation. Addition of SFO modified the polymorphic behavior of milk fat, most likely owing …

1. Introduction

The sequencing of nucleic acids and the subsequent analysis of their encoded the genes and proteins has revolutionized biological sciences and allowed for the determination of evolutionary origins and biochemical potential of organisms. While the technology to determine molecular sequence data has become extremely powerful in terms of both automation and thoughput, sequence analysis technology has lagged behind, unable to efficiently keep up with the vast amount of sequence data being generated both in individual labs and by researchers worldwide. The foundation of robust sequence analysis is dependent on the building and maintaining of project sequence databases (PSD) …

A Probabilistic Approach To Model The Nonisothermal Nucleation Of Triacylglycerol Melts, Alejandro G. Marangoni, Thomas C. Aurand, Silvana Martini, Michel Ollivon

Nutrition, Dietetics, and Food Sciences Faculty Publications

Crystallization studies are usually performed under isothermal conditions. Kinetic parameters characterizing the isothermal nucleation and growth processes can be obtained using classical nucleation and growth models. However, crystallization regimes found in nature, as well as those used in food and pharmaceutical processing, are rarely isothermal. Focusing on the nucleation stage, the approach followed in this work was to define a new parameter to characterize the driving force of nucleation, the supercooling-time exposure (β), which not only depends on the difference between the melting temperature (Tm) and the onset temperature of nucleation (Tc) ΔTc but also on the induction time of …

The Water Vapor Permeability Of Polycrystalline Fat Barrier Films, Silvana Martini, D. A. Kim, M. Ollivon, A. G. Marangoni

Nutrition, Dietetics, and Food Sciences Faculty Publications

The water vapor permeability of fat barrier films has been associated with structural characteristics such as polymorphism, crystal size, and chemical composition, among others. However, no mechanistic models have been proposed to describe this relationship. In this study, we have determined the effects of processing conditions on the structure and physicochemical characteristics of four fats and their relationship to water vapor permeability. Results suggest that the solids' volume fraction and the domain size of the fat crystals seem to be the most important factors controlling water vapor migration. Moreover, materials with relatively large crystalline domains will yield malleable films with …

Queen Weights Of Polygyne Solenopsis Invicta And S. Xyloni Suggest Reduced Competitive Ability, Ricardo A. Ramirez, D C. Thompson

Biology Faculty Publications

Solenopsis invicta Buren populations were confirmed in southern New Mexico, resulting in a quarantine of Doña Ana County in 1998; however, Solenopsis xyloni McCook remains the dominant fire ant. This study compared the queen weights and egg production of polygyne colonies of both species. There was no difference in live weights of the major worker caste; however, queens were very different in weight. In this study, S. invicta queens weighed almost twice as much as S. xyloni (S. invicta = 11.32 ± 0.25mg vs. S. xyloni = 6.40 ± 0.30mg) and produced over 50% as many eggs as S. xyloni. …

Endothelial Cell Cortactin Coordinates Icam-1 Clustering And Actin Cytoskeleton Remodeling During Polymorphonuclear Leukocyte Adhesion And Transmigration, Jennifer Kowalski

Scholarship and Professional Work - LAS

Endothelial cell ICAM-1 interacts with leukocyte beta2 integrins to mediate adhesion and transmit outside-in signals that facilitate leukocyte transmigration. ICAM-1 redistribution and clustering appear necessary for leukocyte transmigration, but the mechanisms controlling ICAM-1 redistribution and clustering have not been identified. We recently reported that Src kinase phosphorylation of endothelial cortactin regulates polymorphonuclear cell (PMN) transmigration. In this study, we tested the hypotheses that the Src family kinase-cortactin pathway mediates association of ICAM-1 with the actin cytoskeleton and that this association is required for ICAM-1 clustering and leukocyte transmigration. Cross-linking ICAM-1 induced cytoskeletal remodeling and a decrease in ICAM-1 lateral mobility, …
