Central American Media: A Comparative Study of Media Industries in Guatemala, Nicaragua, Honduras, El Salvador, and Costa Rica.
The five countries that lie on the isthmus connecting North and South America have endured a past of colonialism, civil war, and natural disaster. As these countries evolve in the 21st century, growing economies and political peace provide a promising outlook for the citizens of these nations. The media industries in these nations have varying levels of development which are explored in this thesis. Using Michael Porter's 1990 framework and a case study methodology, this thesis explores the differences and similarities of media industries in Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica, and what may be done to ensure future success in an increasingly global world.

Characteristics of Preservice Teachers Learning Parent Involvement Practices.
Numerous models of IS success and technology acceptance their extensions have been proposed and applied in empirical. This study continues this tradition and extends the body of knowledge on the topic of IS success by developing a more comprehensive model for measuring IS success and technology acceptance within a government organization. The proposed model builds upon three established IS success and technology acceptance frameworks namely the DeLone and McLean (2003), Venkatesh et al.'s (2003) unified theory of acceptance and use of technology (UTAUT), and Wixom and Todd (2005). The findings from this study provide not only a comprehensive IS success assessment model but also insights into whether and how IS success models are influenced by application variables as applied within a government organization. Exploratory factor analysis and confirmatory factor analysis were performed for instrument refinement and validity test of the existing and proposed models. Using data from employees of a local government municipal, the comprehensive model explained 32 percent variance. Four of the hypothesis were fully supported five were not supported, and four were partially supported. In addition, the results suggest that behavioral intention may not be the best predictor of technology acceptance in a mandatory environment.

Characterizing Storm Water Runoff from Natural Gas Well Sites in Denton County, Texas
In order to better understand runoff characteristics from natural gas well sites in north central Texas, the City of Denton, with assistance through an EPA funded 104b3 Water Quality Cooperative Agreement, monitored storm water runoff from local natural gas well sites. Storm water runoff was found to contain high concentrations of total suspended solids (TSS). Observed TSS concentrations resulted in sediment loading rates that are similar to those observed from typical construction activities. Petroleum hydrocarbons, in contrast, were rarely detected in runoff samples. Heavy metals were detected in concentrations similar to those observed in typical urban runoff. However, the concentrations observed at the gas well sites were higher than those measured at nearby reference sites. Storm water runoff data collected from these sites were used to evaluate the effectiveness of the water erosion prediction project (WEPP) model for predicting runoff and sediment from these sites. Runoff and sediment predictions were adequate; however, rainfall simulation experiments were used to further characterize the portion of the site where drilling and extraction operations are performed, referred to as the "pad site." These experiments were used to develop specific pad site erosion parameters for the WEPP model. Finally, version 2 of the revised universal …

Child Soldiers and Intrastate Armed Conflicts: An Analysis of the Recruitments of Child Soldiers in Civil Wars Between 2001 and 2003.
This thesis examines why some governments and rebel organizations but not others recruit children to be child soldiers. The theory posits that if a country fights in a civil war of long duration, armed groups are more likely to recruit children as soldiers. I find that the probability of child soldier recruitment increases when a country experiences following conditions: a longer duration of civil war, a large proportion of battle deaths, a large number of refugees, a high infant mortality rate, and the presence of alluvial diamonds. An increase in education expenditures and civil liberties would decrease the probability of child soldier recruitments.

Children of Teenage Mothers: School Readiness Outcomes and Predictors of School Success.
The purpose of this study was to examine the effects of teenage motherhood on the school readiness, literacy skills, and parental involvement of children participating in the Home Instruction for Parents of Preschool Youngsters (HIPPY) early intervention program, as well as make recommendations for optimal outcomes. Study children were participants in HIPPY at five diverse, urban school districts. Using a mixed method design, this study examined the results of quantitative measures of children's school readiness, literacy skills, and parent involvement along with qualitative data collected through mothers' responses to two, open-ended questions related to their satisfaction with HIPPY. According to results of independent samples t-test, mean scores on school readiness and parent involvement measures were not statistically significantly different for the children of teenage mothers and the children of traditional age mothers. However, there were moderate effect sizes for parent involvement and physical development indicating some practical significance. Chi-square results of literacy skills indicated that the children of teenage mothers were almost twice as likely [c2 (1, N = 36) = 4.21, p < .05] to have literacy skills that were "not on grade level" according to scores on the TPRI/Tejas. Descriptive discriminant analysis (DDA) indicated that the multivariate relationship …

Choices in Reinforcer Delivery
The current study consisted of two experiments, both of which were comparisons of choice conditions replicated across four participants. Four typically-developing pre-school children participated in this study. Experiment 1 evaluated participants' preference for choosing consequent stimuli prior to engaging in academic tasks (pre-session choice) versus choosing consequent stimuli each time criterion for reinforcement had been met within the session (within-session choice). In Experiment 2, preference for choice-making was evaluated when outcomes for both choice and no-choice conditions were identical. For two participants, results indicated strong preference for choice-making.

Choral Resonance: Re-Examining Concepts of Tone and Unification.
Resonant singing creates possibilities with dynamic shading, subtlety of phrasing, and rich vibrant tone that astonishes listeners. Choral singing that employs resonance as a fundamental ensemble virtue yields impressive results that lend themselves well to the varying demands of any choral score. Fortunately, choruses of every level can benefit from an increased understanding of the basic principles of resonance in the singing voice. Research on issues of upper partial energy and the presence of the singer's formant in a choral ensemble has been limited in approach. Many published studies regarding upper partial energy in the choral ensemble are based on what the ensemble is already doing, which is linked to the teaching of that specific director and that specific choir. Research must include a wider range of aesthetic choices with regard to choral unification. Through examining spectrograms that represent the sound of some of the most renowned choirs, it is possible to see that many of these ensembles are producing tone that contains a high level of upper formant energy. Interviews with established conductors reveal approaches and teaching methodologies that reinforce this type of singing. It is possible to teach the individuals in a choir to increase the level of …

Climate Change and Water: Technical Paper VI
The Technical Paper addresses the issue of freshwater. Sea level rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species.

Climate Change Mitigation Negotiations, With An Emphasis on Options For Developing Counteries
Climate change is one of the greatest threats to our planet and its people. Reducing emissions of greenhouse gases (GHG) is called mitigation. Responding to the impacts of climate change is called adaptation. A certain amount of adaptation will be necessary, no matter what we do. But, there will come a point where it will not be possible to adapt our way out of the problem.

Climate Models: An Assessment of Strengths and Limitations
This Synthesis and Assessment Product (SAP 3.1) focuses on the Climate models. Scientists extensively use mathematical models of Earth's climate, executed on the most powerful computers available, to examine hypotheses about past and present-day climates. Development of climate models is fully consistent with approaches being taken in many other fields of science dealing with very complex systems. These climate simulations provide a framework within which enhanced understanding of climate-relevant processes, along with improved observations, are merged into coherent projections of future climate change. This report describes the models and their ability to simulate current climate.
