An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry

Resource recovery is an attractive alternative to the waste disposal problem. The chief by-product of this process, refuse derived fuel (RDF) can be co-fired in traditional coal burning facilities. The cement industry is a potential user of RDF. This study, based on a test burn done at Texas Industries Inc. in Midlothian, Texas, demonstrated the technical, environmental, and economic feasibility of using RDF fuel in a cement kiln. Technically, the cement showed no deleterious effects when RDF was substituted for coal/natural gas at 20% by Btu content. Environmentally, acid rain gases were reduced. Economically, RDF was shown to be a cost effective fuel substitute if a resource recovery facility was erected on site.

Class and Freedom of Choice in the Marriage Patterns of Antebellum Texas Women (open access)

Class and Freedom of Choice in the Marriage Patterns of Antebellum Texas Women

Little scholarly analysis has been devoted to the hypothesis that antebellum Texas women generally married within their own socioeconomic (slaveholding) class, and thus had only limited choice in the selection of marriage partners. This quantitatively based investigation suggests that the popular image should be carefully qualified. This study reveals that although a majority of Texas women who married during the early 1850s chose men who had the same slaveholding status, a significant minority crossed class lines. By using marriage records of the period in correlation with information gleaned from the census, conclusions were reached. Contemporary women's diaries, letters and reminiscences were investigated, in addition to a historiography of marriage in the South, which created the background for this study.

A Study of the Relationship Between the Use of Color for Text in Computer Screen Design and the Age of the Computer User

This study addresses an individual's performance, relating it to eyesight changes due to the aging of the individual and to color computer screens used for computer-based-instruction not designed specifically for older students. This study determines how existing research in gerontology, human-computer interface, and color use in visual graphics can be applied to the design of computer screen displays containing color text and backgrounds and how various color combinations will affect performance by adult learners forty years of age and older. The results of this research provide software developers and instructional designers guidelines to use when designing computer screen displays for use in instructional computing settings involving older adults.

Personality Profiles of Hospitality Students: A Comparison of These Traits to Those Preferred by the Hospitality Industry (open access)

Personality Profiles of Hospitality Students: A Comparison of These Traits to Those Preferred by the Hospitality Industry

One problem facing the hospitality industry today is turnover. Management turnover rates of 50 and 75 percent continue to plaque all segments of the industry. Personality type theory holds that people are happier in environments that are compatible with their personalities. This study examines 229 undergraduate students enrolled in hospitality education at the University of North Texas. The Myers Briggs Type Indicator was administered to these students to determine their predominant personality types, and to compare these types to those desired by hospitality industry professionals for success within the industry. Variables such as gender, work experience, and classification were also examined in comparison to student personality types.

Perception of Punitive Childhood Experiences, Adult Coping Mechanisms and Psychological Distress (open access)

Perception of Punitive Childhood Experiences, Adult Coping Mechanisms and Psychological Distress

Differences in college student's psychological well-being, extrapunitiveness, and intropunitiveness were related to the presence or absence of maltreatment during childhood years, and its acknowledgement by the student. Subjects were 56 male and 85 female undergraduate students at the University of North Texas. Subjects were given structural scale v.3 of the California Psychological Inventory (CPI), the Extrapunitive (E), and Intropunitive (I) indices of the Hostility-Direction of Hostility Questionnaire (HDHQ), and the Physical Punishment scale (PP-scale) of the Assessing Environments Questionnaire (AEIII). Results indicate no significant differences in psychological well-being, extrapunitiveness, or intropunitiveness, which would be explained by the presence of maltreatment or its acknowledgement.

Gender Bias in Textbooks in Selected Kinesiology Courses in Texas Colleges and Universities (open access)

Gender Bias in Textbooks in Selected Kinesiology Courses in Texas Colleges and Universities

Gender bias, as well as other forms of discrimination, have been deemed unacceptable by today's standards. Research indicates that while it is not obtrusive, gender bias in the media is pervasive and potent. Textbooks are a communication medium which not only convey the requisite knowledge of a particular subject, but also, subliminally, norms and expectations of behavior for individuals in society. These subliminal messages, sometimes termed the hidden curriculum, may serve as inhibitors of an individual's aspirations and goals. The purposes of this study, therefore, were to analyze current kinesiology literature to determine if gender bias was present and if so, was the gender of the author associated with the presence of bias. A third purpose was to compare the results of this study with previous related research.
