A correlation of the Edaphic Factors with the Vegetation of the Woodbine sands, Denton County, Texas

Description: The purpose of this study was to correlate the Vegetation of the Woodbine Sands with the edaphic factors. In the laboratory an analysis of the edephic factors was made of the twenty-two soil types collected from the three formations. The results of these and other analysis are shown in tables and graphs. The results indicate that the vegetational cover of an area that is uniform in its origin and in its resident soil factors is determined by the edaphic factors present.

A Model for a Humanized Work Climate, and the Effects of Occupation Choice and Education Level on Students' Attitudes Toward an Operational Definition of Such a Climate

Description: This investigation determines students' attitudes toward a "humanized" work climate. The possibility that attitudes developed before entering the labor force contribute to the lack of such environments is the basis of the research design. A review of motivation theories, relevant research and experiences of some "humanized" firms precedes the development of a model for a humanized climate. The three main elements of the model--team activity, the product, and the self-concept--are interconnected by elements such as self-control, job performance, autonomy, goal definition, and learning. The research questionnaire, a thirty-onestatement, Likert-type instrument, elicits attitudes about the time-task aspect of Kahn's "Work-Module." A Cronbach Alpha Coefficient of 0.74 indicates an acceptable reliability. The subjects, all male, were seventy senior business students at North Texas State University, fifty-six high school senior academic students from the Richardson, Texas ISD, thirty-two high school vocational students from the Garland, Texas ISD, and twenty-nine college vocational students from the El Centro Branch of the Dallas County Community College System. A 2 x 2 analysis of variance revealed a significant difference (P = 0.0038) between attitudes of vocational and non-vocational students. Vocational students apparently value an autonomous work situation. They prefer a job which permits them to develop and use four or five work skills, because that type of job appeals to their self-concept and promises economic and vocational security. However, students in academic programs consider their economic and job security best protected by structured and specialized jobs. Individuals who aspire to own their own business also prefer the structured climate; others prefer the autonomous environment. The difference in attitude between the two education levels was significant at P < 0.20. The education process appears to be associated with preference for a more structured work climate, in the case of both academic and vocational students. Education also appears to ...

Effectiveness of a Web-based Course in Facilitating the Integration of Technology Into Early Childhood Curricula.

Description: Although technology is available and used in early childhood classrooms, little is known about what early childhood teachers believe about the use of technology and how technology is integrated into early childhood curricula. This study was designed to (a) determine the beliefs of early childhood teachers about technology integration into early childhood curricula and (b) describe the extent to which early childhood teachers integrate technology in their early childhood curricula. The participants included 39 prekindergarten teachers who volunteered to participate in a technology integration project. The treatment group accessed a Web-based technology integration training program and participated in two classroom observations, along with completing an attitudinal questionnaire pretest and posttest. The Prekindergarten Web-based Technology Integration Training included four modules each expanding the following themes: (a) national and state standards and guidelines for technology; (b) setting up a computer center; (c) integrating technology; (d) using the digital camera. The control group participated in two classroom observations without the benefit of the Web-based technology integration training program and completed the attitudinal questionnaire pretest and posttest. Results indicate that Prekindergarten teachers believe that technology can enhance a child's learning, but there was no statistically significant difference between the control and the treatment group.

The Effectiveness of Denton State School's Developmental Evaluation Form in Evaluating an Operant Training Program for Severely Retarded Boys

Description: The problem of this study was to evaluate Denton State School's Developmental Evaluation Form as it is now being used in their operant conditioning techniques in certain basic self-help areas, and to suggest a more effective and informative method of scoring the Evaluation Form. The present method of scoring this evaluation form requires that -all items at each developmental level be passed in order to receive credit for that level. No partial credit is given at any level. This method of scoring yields a developmental level at which. the individual is functioning. It does not, however, point out the total overall development of the individual. The present type of basal developmental scoring is not as discriminating as far as picturing an individual's total development as the one which will be suggested.

Life of the Enlisted Soldier on the Western Frontier, 1815-1845

Description: In contrast to the relatively rapid changes occurring in the modern American army, the period between the end of the War of 1812 and the beginning of the Mexican War offers a definite period for a study of military life when reform came slowly. During the period of study, leaders made few attempts to reform the general structure of the military institution as a social system. On the other hand, many changes can be discerned which improved weaponry and equipment, tactics, supply and administrative procedures, moral guidance, recreational facilities, and pay.

Wind Energy-related Wildlife Impacts: Analysis and Potential Implications for Rare, Threatened and Endangered Species of Birds and Bats in Texas

Description: Texas currently maintains the highest installed nameplate capacity and does not require publicly available post-construction monitoring studies that examine the impacts of wind energy production on surrounding fauna. This thesis examines potential wind energy impacts on avian and bat species in Texas through a three-part objective. The first two objectives synthesize literature on variables attractive to species within wind development areas and estimate impacted ranges outside of Texas, based on studies examining wind energy's environmental impacts. The third objective focuses on Texas wind development potential for interaction with rare, threatened and endangered species of birds and bats using GIS analysis with a potential hazard index (PHI) model, which addresses broad-spectrum, high risk variables examined within the first two objectives. Assuming areas with higher wind speeds have potential for wind development, PHI values were calculated for 31 avian and ten bat species, based on an analysis of species range data obtained from the Texas Parks and Wildlife Department and wind data obtained from the National Renewable Energy Laboratory. Results indicate one avian species, Tympanuchus pallidicinctus, is at high risk for wind development interaction on an annual basis, with 20 species of birds and nine species of bats at higher risk during the spring season. This macro-scale approach for identifying high risk species in Texas could be used as a model to apply to other conterminous states' preliminary evaluation of wind energy impacts.

Agreement Between Self and Other Ratings in Multi-Rater Tools: Performance, Alternative Measures, and Importance.

Description: Multi-rater tools also referred to as 360-degree feedback tools, are frequently used in addition to traditional supervisory appraisals due to sources (i.e., supervisor, peer, direct report) unique perspectives and opportunities to view different aspects of job performance. Research has found that the differences among sources are most prevalent between self and other ratings, and the direction of agreement is related to overall job performance. Research has typically focused on one form of agreement, the direction of an individual's self-ratings compared to others' ratings. The current study expanded on past research on rater agreement using a data set (n = 215) consisting of multi-rater data for professionals participating in a leadership development process. The study examined the ability to predict job performance with three different measures of self-other agreement (i.e., difference between overall mean scores (difference), mean absolute difference across items (difference), and mean correlation across items (similarity)). The study also examined how the relationships may differ across performance dimensions. The final purpose was to explore how the importance of the performance dimensions, as rated by the participant, may moderate the relationship between self-other agreement and job performance. Partial support for study's hypotheses was found. The direction and difference measures of agreement on the overall multi-rater tool and performance dimensions accounted for a significant amount of the variance in job performance. The relationship between the similarity measure of agreement and job performance, and the moderating effect of importance were not supported in the current study.

Personality and Rater Leniency: Comparison of Broad and Narrow Measures of Conscientiousness and Agreeableness

Description: Performance appraisal ratings provide the basis for numerous employment decisions, including retention, promotion, and salary increases. Thus, understanding the factors affecting the accuracy of these ratings is important to organizations and employees. Leniency, one rater error, is a tendency to assign higher ratings in appraisal than is warranted by actual performance. The proposed study examined how personality factors Agreeableness and Conscientiousness relate to rater leniency. The ability of narrower facets of personality to account for more variance in rater leniency than will the broad factors was also examined. The study used undergraduates' (n = 226) evaluations of instructor performance to test the study's hypotheses. In addition to personality variables, students' social desirability tendency and attitudes toward instructor were predicted to be related to rater leniency. Partial support for the study's hypotheses were found. The Agreeableness factor and three of the corresponding facets (Trust, Altruism and Tender-Mindedness) were positively related to rater leniency as predicted. The hypotheses that the Conscientiousness factor and three of the corresponding facets (Order, Dutifulness, and Deliberation) would be negatively related to rater leniency were not supported. In the current sample the single narrow facet Altruism accounted for more variance in rater leniency than the broad Agreeableness factor. While social desirability did not account for a significant amount of variance in rater leniency, attitude toward instructor was found to have a significant positive relationship accounting for the largest amount of variance in rater leniency.

Présentations de la Grammaire et Représentations du Discours Dans les Manuels de Français Publiés aux États-Unis: une Étude Diachronique

Description: This study partially replicates and re-explores specific dimensions of a textbook analysis of the presentation and use of specific grammatical elements and sociolinguistic variants in textbooks published in the United States for learners of French. Authenticity is situated as a central construct in the analysis of interrogatives, relative pronouns, and the negative particle ne in selected textbooks and ancillary materials. The findings reveal that little progress has been made over the past twenty years in integrating authentic representations of discourse into French-as-a-foreign-language textbooks.

Privacy Concerns and Personality Traits Influencing Online Behavior: A Structural Model

Description: The concept of privacy has proven difficult to analyze because of its subjective nature and susceptibility to psychological and contextual influences. This study challenges the concept of privacy as a valid construct for addressing individuals' concerns regarding online disclosure of personal information, based on the premise that underlying behavioral traits offer a more reliable and temporally stable measure of privacy-oriented behavior than do snapshots of environmentally induced emotional states typically measured by opinion polls. This study investigated the relationship of personality characteristics associated with individuals' general privacy-related behavior to their online privacy behaviors and concerns. Two latent constructs, Functional Privacy Orientation and Online Privacy Orientation, were formulated. Functional Privacy Orientation is defined as a general measure of individuals' perception of control over their privacy. It was measured using the factors General Disclosiveness, Locus of Control, Generalized Trust, Risk Orientation, and Risk Propensity as indicator variables. Online Privacy Orientation is defined as a measure of individuals' perception of control over their privacy in an online environment. It was measured using the factors Willingness to Disclose Online, Level of Privacy Concern, Information Management Privacy Concerns, and Reported Online Disclosure as indicator variables. A survey questionnaire that included two new instruments to measure online disclosure and a willingness to disclose online was used to collect data from a sample of 274 adults. Indicator variables for each of the latent constructs, Functional Privacy Orientation and Online Privacy Orientation, were evaluated using corrected item-total correlations, factor analysis, and coefficient alpha. The measurement models and relationship between Functional Privacy Orientation and Online Privacy Orientation were assessed using exploratory factor analysis and structural equation modeling respectively. The structural model supported the hypothesis that Functional Privacy Orientation significantly influences Online Privacy Orientation. Theoretical, methodological, and practical implications and suggestions for analysis of privacy concerns and behavior are presented.

Comparing Three Effect Sizes for Latent Class Analysis

Description: Traditional latent class analysis (LCA) considers entropy R2 as the only measure of effect size. However, entropy may not always be reliable, a low boundary is not agreed upon, and good separation is limited to values of greater than .80. As applications of LCA grow in popularity, it is imperative to use additional sources to quantify LCA classification accuracy. Greater classification accuracy helps to ensure that the profile of the latent classes reflect the profile of the true underlying subgroups. This Monte Carlo study compared the quantification of classification accuracy and confidence intervals of three effect sizes, entropy R2, I-index, and Cohen’s d. Study conditions included total sample size, number of dichotomous indicators, latent class membership probabilities (γ), conditional item-response probabilities (ρ), variance ratio, sample size ratio, and distribution types for a 2-class model. Overall, entropy R2 and I-index showed the best accuracy and standard error, along with the smallest confidence interval widths. Results showed that I-index only performed well for a few cases.

Style and the Art of Chaim Soutine: Ethnicity, Nationalism and Geography in the Critical Reception and Historiography

Description: This thesis argues that art criticism published during Soutine's lifetime emphasizes ethnicity, nationalism and geography in discussions of the artist's style. These critical discussions have influenced the historiography of Soutine published after his death, resulting in a continued emphasis on style that includes references to ethnicity. Ethnicity, nationalism and geography are identified in the critical reception and historiography by noting references, both specific and implied, to Jewishness, French art, and foreign status (among others). These references are analyzed in terms of existing scholarship that addresses concepts of ethnicity and nationalism, and with consideration to how the critical reception has impacted the historiography.

Competency to Stand Trial: A Systematic Evaluation and Validation of the GCCT, MacCAT-CA, and ECST as Competency Measures

Description: Competency to stand trial cases constitute the largest percentage of forensic referrals for clinical psychologists. Furthermore, research suggests that the use of forensic measures facilitates the decisions of competency made by forensic examiners. This study investigated the construct validity of three competency measures: (a) the GCCT-MSH, (b) the MacCAT-CA, and (c) the ECST with 100 adult males incarcerated at the Tarrant County Jail in Fort Worth, TX. Construct validity was investigated via the use of a multitrait-multimethod research design for the three-prong conceptualization of the Dusky standard. Results indicated that current competency measures do an adequate job of assessing for factual understanding, but lack construct validity for two prongs: rational understanding and the ability to consult with counsel. In addition, the atypical presentation scales of the both GCCT and the ECST performed well at screening individuals for feigning. Finally, prediction of competency from clinical variables was also investigated. Psychotic symptoms and overall impairment were the strongest predictors of incompetency.

Neuropsychological Predictors of Incompetency to Stand Trial

Description: This study investigated the effect of cognitive factors on competency to stand trial. Previous researchers have investigated how psychological variables --such as psychosis and intelligence--contribute to incompetency. Although several researchers have established that intelligence contributes to incompetency, very few have investigated the role of specific cognitive abilities within the realm of intelligence. This study investigated the performance of 55 defendants referred for competency restoration on neuropsychological measures. Specifically, competent defendants and incompetent defendants were compared on several measures assessing functioning in seven cognitive domains. Competent defendants performed significantly better than incompetent defendants on measures of verbal comprehension, social judgment, verbal memory, and executive functioning. Competent and incompetent defendants did not differ on attention, visual spatial skills, or nonverbal memory.

Size Dependence in the Electrical Conductivity of Bismuth

Description: In the present investigation, measurements were made at liquid-helium temperatures on single-crystal bismuth samples which had a stair-step geometry in order to study several thicknesses during one helium run. These samples were also thinned to extend the thickness range of the steps to a thinner region. In addition J.E. Parrott's theory is extended to include a diagonal anisotropic relaxation-time tensor and the effect of holes on the size effect. A discussion of the theory of Parrott, and the extension of Parrott's theory in connection with the experimental results is presented.
