Eutrophication Monitoring and Prediction

Eutrophication Monitoring and Prediction

Date: December 1993
Creator: Cairns, Stefan H., 1949-
Description: Changes in trophic status are often related to increases or decreases in the allocthonous inputs of nutrients from changes in land use and management practices. Lake and reservoir managers are continually faced with the questions of what to monitor, how to monitor it, and how much change is necessary to be considered significant. This study is a compilation of four manuscripts, addressing one of these questions, using data from six reservoirs in Texas.

Date: August 2006
Creator: Kraus, Janine Stillwell
Description: This study assessed alumni of the College and University Teaching Program at the University of North Texas and how they perceived the training they received. Three hundred sixty alumni holding a college and university teaching degree were surveyed. One hundred forty-two usable questionnaires were returned. A response rate of 39.4 % was achieved. A survey instrument was used to gather alumni perceptions of learning experiences, academics, and professional benefits as a result of earning a doctorate in the major of college and university teaching at the University of North Texas. Alumni were asked their perceptions on the following: 1) the quality of graduate professional education in college and university teaching degree program, 2) whether they thought the goals and objectives of the program were met, and 3) their recommendations regarding the college and university teaching degree program. It is the overall opinion of the alumni that the quality of the graduate education in college and university teaching degree program was high. The majority of alumni indicated that the program should be reinstated and continued and if the program was still available they would recommend it to others.

Evaluating a positive parenting curriculum package: An analysis of the acquisition of key skills.

Evaluating a positive parenting curriculum package: An analysis of the acquisition of key skills.

Date: August 2007
Creator: Berard, Kerri P.
Description: With the increase in survival for children with cancer, part of the focus of current research is aimed towards evaluating how these children are adapting psychosocially. Neurocognitive deficits have been well established. However, there are multiple facets encompassing quality of life, including general mental health, lifestyles and health behaviors, and academic and cognitive functioning. The relationship between neurocognitive and psychosocial functioning has yet to be thoroughly evaluated. The purpose of this study was to investigate the relationship between neurocognitive and psychosocial functioning in survivors of brain tumors and acute lymphoblastic leukemia. Data was collected from existing archival database comprised of patients of the at Cook Children's Medical Center in Texas. The sample consisted of 177 patients between the ages of 3 and 12 who were at least two years post-diagnosis. Measures used included the NEPSY and the Behavioral Assessment for Children. Statistical analyses included a several one-way analysis of variances, an independent samples t-test, a univariate analysis of variance, a hierarchical multiple regression, and odds ratio analyses. Results indicated survivors treated with neurosurgery alone appear to be less at risk for developing behavior problems than other treatment modalities. Also, brain tumor survivors demonstrate more problematic behaviors than survivors of acute ...

Evaluating and Blending Multimedia Mobile Applications into Technical Training

Evaluating and Blending Multimedia Mobile Applications into Technical Training

Date: May 2011
Creator: Moore, Billy R.
Description: This study in the aerospace ground equipment (AGE) apprentice course at Sheppard Air Force Base, Texas, examined the use of mobile digital devices to determine which device leveraged the best results and was most compatible with military technical training requirements. The sample consisted of 160 students who attended the course between January and June, 2010. Three devices loaded with course materials were issued to the students, who used the devices in the classroom and were encouraged to use the devices to enhance their study time after class. Quantitative data were obtained by comparing block test scores to determine if any device produced a significant change in student learning. Qualitative data were collected from surveys administered to instructors and students to measure which device instructors and students found easiest to understand and use, and student satisfaction with the device. An analysis of variance (ANOVA) revealed a statistically significant difference (p < .05) in the block test mean scores between groups using mobile devices and the students in the control group that had no device. Post hoc comparisons on each block showed that there was a statistically significant difference between students using the smartphone and students using the other devices, but no ...

Evaluating Appropriateness of Emg and Flex Sensors for Classifying Hand Gestures

Evaluating Appropriateness of Emg and Flex Sensors for Classifying Hand Gestures

Date: May 2013
Creator: Akumalla, Sarath Chandra
Description: Hand and arm gestures are a great way of communication when you don't want to be heard, quieter and often more reliable than whispering into a radio mike. In recent years hand gesture identification became a major active area of research due its use in various applications. The objective of my work is to develop an integrated sensor system, which will enable tactical squads and SWAT teams to communicate when there is absence of a Line of Sight or in the presence of any obstacles. The gesture set involved in this work is the standardized hand signals for close range engagement operations used by military and SWAT teams. The gesture sets involved in this work are broadly divided into finger movements and arm movements. The core components of the integrated sensor system are: Surface EMG sensors, Flex sensors and accelerometers. Surface EMG is the electrical activity produced by muscle contractions and measured by sensors directly attached to the skin. Bend Sensors use a piezo resistive material to detect the bend. The sensor output is determined by both the angle between the ends of the sensor as well as the flex radius. Accelerometers sense the dynamic acceleration and inclination in 3 ...

Evaluating e-Training for public library staff:  A quasi-experimental investigation.

Evaluating e-Training for public library staff: A quasi-experimental investigation.

Date: August 2009
Creator: Dalston, Teresa
Description: A comparative evaluation framework of instructional interventions for implementation of online training for public library staff would enable a better understanding of how to improve the effectiveness, efficiency and efficacy of training in certain training environments. This dissertation describes a quasi-experimental study of a two-week, asynchronous online training course that was provided at four levels of instructional intervention to public library staff in the United States. The course content addressed the complex issues of difficult patron policy development and situational coping techniques. The objective of the study was to develop and demonstrate a theoretically grounded, evidence-based impact evaluation framework. The framework was used to assess the relative impact of an online course for public librarians at four levels of instructional intervention. The researcher investigated the relationships between the type of e-Training instructional interventions and the short- and long-term impacts on participants' knowledge, self-efficacy, and workplace performance. The study used a longitudinal, quasi-experimental design that included a pretest, posttest and three-month delayed posttest with follow-up survey. 194 participants completed all three phases of the study. The evaluation tools measured course content related knowledge and self-efficacy at all three phases (pretest, posttest, and delayed posttest) and assessed workplace application of training at ...

Evaluating Fish Impingement and Entrainment at the Comanche Peak Steam Electric Station

Evaluating Fish Impingement and Entrainment at the Comanche Peak Steam Electric Station

Date: May 1996
Creator: Bauml, George A. (George Arthur)
Description: This study was designed to determine if impingement and entrainment by cooling water intake at the Comanche Peak Steam Electric Station have an adverse impact upon the Squaw Creek Reservoir fish population. The yearly impingement of fish was estimated to be 262,994 of 14 species. The threadfin shad (Dorosoma petenense) accounted for 96% of this total. Entrainment of eggs and larvae for a five month period was estimated to be 15,989,987 and 42,448,794 respectively. Two fish population studies were performed on Squaw Creek Reservoir to help assess impact. It was determined that the losses due to impingement and entrainment have no adverse impact upon the fish population of Squaw Creek Reservoir.

Evaluating Preventative Interventions for Depression and Related Outcomes: a Meta-analysis

Evaluating Preventative Interventions for Depression and Related Outcomes: a Meta-analysis

Date: August 2014
Creator: González, David Andrés
Description: The burden of depression requires modalities other than individual psychotherapy if we are to reduce it. Over the past two decades preventative programs for depression have been developed and refined for different populations. The six years since the last meta-analysis of preventative interventions—inclusive of all program types—have seen a number of new studies. The current study used the greater statistical power provided by these new studies to analyze moderators of, and sub-group differences in, the effect of these interventions on depression. Moreover, this meta-analysis synthesized effect sizes for outcomes other than, but often related to, depression (e.g., anxiety) and for within-group change scores with the goal of better informing program implementation and evaluation. Twenty-nine studies met inclusion criteria and indicated that small, robust effects exist for reductions in depression diagnoses and symptomatology. Significant effects were also observed for anxiety, general health, and social functioning.
