Use of Bio-Product/Phase Change Material Composite in the Building Envelope for Building Thermal Control and Energy Savings

Description: This research investigates the bio-products/phase change material (PCM) composites for the building envelope application. Bio-products, such as wood and herb, are porous medium, which can be applied in the building envelope for thermal insulation purpose. PCM is infiltrated into the bio-product (porous medium) to form a composite material. The PCM can absorb/release large amount of latent heat of fusion from/to the building environment during the melting/solidification process. Hence, the PCM-b… more

Evaluation of the Influence of Non-Conventional Sources of Emissions on Ambient Air Pollutant Concentrations in North Texas

Description: Emissions of air pollutants from non-conventional sources have been on the rise in the North Texas area over the past decade. These include primary pollutants such as volatile organic compound (VOC) and oxides of nitrogen (NOx) which also act as precursors in the formation of ozone. Most of these have been attributed to a significant increase in oil and gas production activities since 2000 within the Barnett Shale region adjacent to the Dallas-Fort Worth metroplex region. In this study, air q… more

Identifying Cultural and Non-cultural Factors Affecting Litter Patterns in Hickory Creek, Texas

Description: Plastic deposition in hydrological systems is a pervasive problem at all geographic scales from loci of pollution to global ocean circulation. Much attention has been devoted to plastic deposition in marine contexts, but little is known about inputs of plastics into local hydrological systems, such as streams. Any attempt to prevent plastic litter must confront people’s behaviors, so archaeological concepts are used to distinguish between various cultural inputs (e.g., littering) and non-cultur… more

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research

Description: Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that soun… more

Influence of Current Parent-Child Relationships on Dating Motivations in Young Adulthood

Description: The purpose of this study was to explore how supportive functions of parent-child relationships influence young adult dating motivations and involvement. Theoretical literature suggests that emotionally supportive homes provide a secure base for children to depend on as they explore themselves and other relationships. However, problematic family ties could be expected to inhibit relationship involvement due to negative past experiences or to encourage involvement as a search for intimacy. A sam… more

It was important to explore variables that affect support because supportive relationships with parents have been related to adolescent adjustment. Past studies have suggested parental conflict has a negative impact on the parent-adolescent relationship. Research in the area of mediators of perceived support in the parent-adolescen… more

A Continuation in the Defining of the Construct of Optimism

Description: One hundred twenty-two undergraduate students at the University of North Texas were administered several different optimism scales and also measures of similar constructs such as hope. Results indicated that most measures of optimism show only low to moderate intercorrelations with other measures of the same construct. Additionally, factor analysis confirmed that the measures of optimism actually appear to be assessing multiple factors and not necessarily optimism alone. Implications of the pre… more
