Adapted Physical Activity Quarterly | Year: 2013

The purpose of this study was to examine the impact of an after school physical activity intervention on adolescents with visual impairments within the context of Social Cognitive Theory. Four adolescents with visual impairments (1 female, 3 males) between 14 and 19 years of age from a residential school for the blind served as participants. We used a range-bound changing criterion single-subject design. Physical activity was measured using ActiGraph accelerometers. Questionnaires were used to obtain information on selected social cognitive theory constructs. Results show that the intervention exerted functional control over the target behaviors (e.g., leisure-time physical activity) during intervention phases. Similarly, changes in scores for selected social cognitive constructs, in particular for outcome expectancy value, suggest a positive relationship between those constructs and physical activity behavior. No maintenance effects were observed. © 2013 Human Kinetics, Inc.

Air quality is known to be a key factor in affecting the wellbeing and quality of life of the general populous and there is a large body of knowledge indicating that certain underrepresented groups may be overexposed to air pollution. Therefore, a more precise understanding of air pollution exposure as a driving cause of health disparities between and among ethnic and racial groups is necessary. Utilizing 52,613 urban census tracts across the United States, this study investigates age, racial, educational attainment and income differences in exposure to benzene pollution in 1999 as a case. The study examines spatial clustering patterns of these inequities using logistic regression modeling and spatial autocorrelation methods such as the Global Moran's I index and the Anselin Local Moran's I index. Results show that the age groups of 0 to 14 and those over 60 years old, individuals with less than 12 years of education, racial minorities including Blacks, American Indians, Asians, some other races, and those with low income were exposed to higher levels of benzene pollution in some census tracts. Clustering analyses stratified by age, education, and race revealed a clear case of disparities in spatial distribution of exposure to benzene pollution across the entire United States. For example, people aged less than 4 years from the western south and the Pacific coastal areas exhibit statistically significant clusters. The findings confirmed that there are geographical-location based disproportionate pattern of exposures to benzene air pollution by various socio-demographic factors across the United States and this type of disproportionate exposure pattern can be effectively detected by a spatial autocorrelation based cluster analysis method. It is suggested that there is a clear and present need for programs and services that will reduce inequities and ultimately improve environmental conditions for all underrepresented groups in the United States. © 2014 Zou et al.

Based on the new theory of MVG to reduce separation caused by shock boundary layer interaction (SBLI), a new optimization method is presented in this paper, mainly to optimize the location of the MVG in front of the shock. The key issue is to generate a proper momentum deficit zone, which can generate a strong shear layer and further strong vortex rings frequently, in front of shock. Several artificial momentum deficit zones (low speed streaks) are tested by LES and the efficiency of reduction of SBLI induced separation is assessed. © 2015 by Chaoqun Liu, University of Texas at Arlington, Arlington, Texas, USA.

Vortical structures like the Λ-vortex and ring-like vortex play a critical role in the boundary layer transition process. In this paper, the mechanisms of the formation of the vortical packets and their mutual interactions are studied by DNS. It is found that the shear layer instability is the key of the vortex generation. On the other hand, in the process of evolution of vortical packets, the vortical structures(including vortex tubes and other kind of rotation cores) will continue to create high shear layers in the boundary layer by both sweeps and ejections. The generation and evolution process of the first ring-like vortex structure is studied in detail. © 2015, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.

Shock-boundary layer interaction (SBLI) is frequently met in supersonic engine inlet flow and external flow. A detailed study on the mechanism of reduction of shock induced flow separation by micro-vortex generator (MVG) is carried out by high order implicit large eddy simulation (ILES). To generate the fully developed turbulent inflow, a series (20,000) of turbulent profiles are given by our previous DNS results. The mechanism of reduction of shock induced flow separation by MVG was originally considered as a result of streamwise vortex mixing. It was thought that the mixing would result in a plump turbulent velocity profile which has stronger separation resistance. It was claimed that turbulent flow has so strong mixing that the velocity profile becomes plump, which lead to reduction of shock induced flow separation. However, according to our LES study reported in this paper, the real mechanism of flow separation reduction is that the shock wave breaks down and disappears when the ring-like vortices generated by MVG are passing through the shock. On the other hand, the vortex structures never break down and is influenced very little when they pass the shock wave. Therefore, the shock induced flow separation is reduced by moving ring-like vortices which were generated by MVG through the manner to break down the shock wave, but mainly not by the streamwise vortex mixing which produces a plump velocity profile in the boundary layer. Details of the investigation on the mechanism are reported in this paper. © 2015 by Chaoqun Liu, University of Texas at Arlington, Arlington, Texas, USA.

Recent studies have suggested that some disadvantaged socio-demographic groups face serious environmental-related inequities in Hong Kong due to the rising ambient urban temperatures. Identifying heat-vulnerable groups and locating areas of Surface Urban Heat Island (SUHI) inequities is thus important for prioritizing interventions to mitigate death/illness rates from heat. This study addresses this problem by integrating methods of remote sensing retrieval, logistic regression modelling, and spatial autocorrelation. In this process, the SUHI effect was first estimated from the Land Surface Temperature (LST) derived from a Landsat image. With the scale assimilated to the SUHI and socio-demographic data, a logistic regression model was consequently adopted to ascertain their relationships based on Hong Kong Tertiary Planning Units (TPUs). Lastly, inequity hotspots were derived using spatial autocorrelation methods. Results show that disadvantaged socio-demographic groups were significantly more prone to be exposed to an intense SUHI effect: over half of 287 TPUs characterized by age groups of 60+ years, secondary and matriculation education attainment, widowed, divorced and separated, low and middle incomes, and certain occupation groups of workers, have significant Odds Ratios (ORs) larger than 1.2. It can be concluded that a clustering analysis stratified by age, income, educational attainment, marital status, and occupation is an effective way to detect the inequity hotspots of SUHI exposure. Additionally, inequities explored using income, marital status and occupation factors were more significant than the age and educational attainment in these areas. The derived maps and model can be further analyzed in urban/city planning, in order to mitigate the physical and social causes of the SUHI effect.

Ion channels, specialized proteins that reside in the cell membrane, shape the electrical activity of nervous systems in all forms of life. Naturally occurring variation (mutations) in genes that encode ion channel proteins can determine electrical properties throughout the nervous system. To better understand the relationship between sequence, structure and function of ion channels, the investigators will use mutations discovered in a potassium channel gene found only among the weakly electric fishes of Africa. They hypothesize that these mutations confer extraordinarily rapid molecular movements, and thus rapid electrical activity, enabling these fishes to produce rapid pulses of electricity used in communication and navigation. The first aim of this grant will be to sequence this gene from a variety of African electric fishes to determine the evolutionary origin of this mutation. The second aim will be to express these genes in-vitro to investigate the physical properties that the mutation confers. This work is important because it gives us greater insight into the role that genetic changes play in determining electrical properties of all types of cells, including heritable diseases of the nervous system (channelopathies), as well as adaptive differences that may shape the nervous system in the evolution of new behaviors. As part of their work, the investigators will train undergraduates, including those from underrepresented groups in science, through coursework and laboratory experiences in molecular evolution, physiology and genomics.

Investigators will investigate the relationship between sequence evolution and biophysical properties of a potassium channel (Kv) exclusively expressed in the electric organ, a derivative of muscle, in African electric fish. Most electric organ discharges (EODs), are used for communication and navigation, and are extraordinarily brief (500 microseconds) within this group, however a few species have secondarily evolved long duration discharges. One Kv channel (kcna7a) is abundantly expressed in the electric organ, and preliminary data suggests high rates of sequence evolution and amino acid substitutions in otherwise highly conserved regions of this protein, likely conferring unique biophysical properties. In the first aim investigators will perform RNAseq on electric organ and muscle tissues from 10 species of African electric fish strategically chosen for their phylogenetic relationships and waveform duration, and examine kcna7a sequence evolution as it relates to EOD phenotypic evolution. In the second aim, investigators will perform site-directed mutagenesis on kcna7a channel genes, guided by discoveries in aim 1, express mutagenized channels in frog oocytes, and perform physiological recordings to determine biophysical properties conferred by specific amino acids. This work will give insights into the genetic basis of rapid evolution of a communication signal involved in speciation; investigate novel amino acid substitutions in a class of medically-relevant ion channels that are universally important in shaping neural activity; potentially provide resources for making channels with hyper-fast kinetics for shaping electrical activity in tissue engineering and provide transcriptomic resources for laboratories studying other aspects of electric organ development and evolution.

The Historically Black Colleges and Universities Undergraduate Program (HBCU-UP) through Targeted Infusion Projects supports the development, implementation, and study of evidence-based innovative models and approaches for improving the preparation and success of HBCU undergraduate students so that they may pursue STEM graduate programs and/or careers. The project at Huston-Tillotson University (HT) seeks to implement inquiry-based courses and undergraduate research to improve and sustain STEM student engagement, training, and transition to STEM careers and graduate study. The curriculum will emphasize real-world research experiences, reconfigure course objectives to emphasize inquiry and problem-based learning, and challenge students to use the critical-thinking skills central to the practice of science. Project activities will advance STEM students knowledge and understanding, enhancing the number and preparedness of the institutions STEM graduates. Thus, this project will have a societal impact on STEM representation from underserved groups.

The goal of Huston-Tillotsons Attaining and Sustaining STEM Excellence with Research Training (HT-ASSERT) program is to improve and sustain the retention, engagement, and scientific training of Natural Science students at HT by emphasizing undergraduate research. The project will enhance undergraduate research through two linked project activities: 1) integrate the science curriculum to highlight inquiry and research, beginning with scientific skill building in introductory courses and culminating in a capstone independent student research project for every student; and 2) develop the material and intellectual infrastructure (lab spaces, faculty expertise, and research collaborations) needed to enact deep and lasting transformation of STEM education at HT. Project activities will integrate with existing STEM programs at HT, including HTs STEM education and campus academic enrichment programs. This project will involve collaborating faculty at the University of Texas at Austin.
