The Effects of Using Children's Literature with Adolescents in the English As a Foreign Language Classroom. (open access)

The Effects of Using Children's Literature with Adolescents in the English As a Foreign Language Classroom.

This study provides quantitative and qualitative data about the effects of using children's literature with adolescents in a language classroom and the role of children's literature in students' second/foreign language development, including listening, speaking, reading, and writing skills. The study presents qualitative data about the role of children's literature in developing more positive attitudes toward reading in the second/foreign language and toward reading in general. With literature being a model of a culture, presenting linguistic benefits for language learners, teaching communication, and being a motivator in language learning, this study presents empirical data that show that inclusion of children's literature in adolescents' second/foreign language classroom promotes appreciation and enjoyment of literature, enhances the development of language skills, stimulates more advanced learning, and promotes students' personal growth.

Athletic Trainers and Psychological Disorders Among Athletes: An Examination of Their Abilities to Recognize, Diagnose and Intervene. (open access)

Athletic Trainers and Psychological Disorders Among Athletes: An Examination of Their Abilities to Recognize, Diagnose and Intervene.

Utilizing an analogue research design conducted via the Internet, this study assessed athletic trainers' abilities to recognize, diagnose, and intervene with a hypothetical athlete experiencing depression, and examined the impact of their gender, athlete gender, and athlete's presenting problem on their decisions. Athletic trainers' perceived competency in using psychosocial interventions with athletes, history of referring athletes to psychology professionals, and training backgrounds in psychology also were examined. Participants (270 male and 370 female certified athletic trainers) were randomly assigned to one of six conditions (Athlete Gender X Presenting Problem). After reading the appropriate vignette, they completed questions related to the athlete's psychological symptoms and diagnosis, referral recommendations, and use of psychosocial interventions if working with the athlete. The vignettes were identical except for the athlete's gender and problem. Overall, athletic trainers accurately identified the athlete's depressive symptoms/diagnosis and need for psychological referral. They rated the athlete significantly higher in Depressive Symptoms than in Anger/Agitation Symptoms and Compulsive Behavioral Symptoms, and as more likely to be experiencing a depressive disorder compared to an adjustment disorder, anxiety disorder, sleep disorder, or substance abuse disorder. Female athletic trainers provided significantly higher ratings of Depressive Symptoms than males and the injured athlete was rated …

Family Influences on Young Adult Career Development and Aspirations (open access)

Family Influences on Young Adult Career Development and Aspirations

The purpose of this study was to examine family influences on career development and aspirations of young adults. Theories and research have examined the influence parents have on children's career development, but because of the multiple factors that influence career choices, understanding the family's influence is complex. The current study utilized ideas from self-determination, attachment, and career development theories to develop a framework for understanding how families influence young adult career development and aspirations. Rather than directly influencing career decisions, the family was proposed to influence processes within individuals that directly influence successful career development. This study used hierarchical regression analyses to test whether different aspects of family relationships and the family environment affect processes within young people, which in turn influence career development. A sample of 99 female and 34 male undergraduate students between 18 and 20 (mean age 18.67) completed questionnaires. Results support the idea that different aspects of the family influence diverse factors of career development and future aspirations. The achievement orientation of the family was predictive of career salience and extrinsic aspirations. Conflict with mothers was predictive of career salience, yet support and depth in the relationship with mothers and low amounts of conflict in the …

Hiring preferences of employers of entry-level biomedical equipment technicians in Texas. (open access)

Hiring preferences of employers of entry-level biomedical equipment technicians in Texas.

This study examined the signaling strength, or marketing power, of the most common qualifications of entry-level biomedical equipment technicians (BMETs) in Texas, based on stated hiring preferences of BMET managers, using order ranking of fictitious resumes. This study also sought to determine whether certification status, education background, military training background as a BMET, or type of employer [hospital or ISO] of the hiring manager had an effect on hiring preference for applicant qualifications of associate degree, military training as a BMET, or certified biomedical equipment technician (CBET) certification candidacy. Participants were asked to rank 16 fictitious resumes representing the most common qualifications of entry-level BMETs and to fill out a background questionnaire regarding their education, military, certification, and employer. The number of times each resume ranked in first place was tabulated and inter-rater reliability was calculated. Resumes with qualifications of associate degree versus military training as a BMET were compared at three levels of work experience. A chi-square test for independence was conducted for the comparisons to determine whether work experience influenced preference. Chi-square tests were also conducted for comparisons of associate degree with candidacy for CBET certification versus associate degree and military training with CBET candidacy versus military training. …

Attachment Processes, Stress Processes, and Sociocultural Standards in the Development of Eating Disturbances in College Women (open access)

Attachment Processes, Stress Processes, and Sociocultural Standards in the Development of Eating Disturbances in College Women

Minimal empirical research using longitudinal data to explore integrative models of eating disorder development exists. The purpose of this study was to further explore multidimensional models incorporating parental attachment, history of stress, appraisal/coping processes, internalization of the thin-ideal, negative affect, body image, and eating disordered behavior using prospective, longitudinal data. The models were evaluated using 238 participants who completed an initial series of self-report questionnaires during their first semester in college and completed follow-up questionnaires 6 months and 18 months later. Structural equation modeling was used to examine the relationships among the factors. Analyses confirmed that college freshman with insecure parental attachment relationships and those with a history of previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition; these conditions predicted increased negative affect and increased eating disturbances. Women who reported experiencing negative affect and those that endorsed internalization of the thin-ideal also reported higher levels of body dissatisfaction; these women engaged in more disordered eating attitudes and behaviors. A second model investigating negative affect as mediating the relationship between the appraisal/coping process and eating disturbances also revealed that experiencing difficulties with the transition to college predicted later …

A Framework of Automatic Subject Term Assignment: An Indexing Conception-Based Approach (open access)

A Framework of Automatic Subject Term Assignment: An Indexing Conception-Based Approach

The purpose of dissertation is to examine whether the understandings of subject indexing processes conducted by human indexers have a positive impact on the effectiveness of automatic subject term assignment through text categorization (TC). More specifically, human indexers' subject indexing approaches or conceptions in conjunction with semantic sources were explored in the context of a typical scientific journal article data set. Based on the premise that subject indexing approaches or conceptions with semantic sources are important for automatic subject term assignment through TC, this study proposed an indexing conception-based framework. For the purpose of this study, three hypotheses were tested: 1) the effectiveness of semantic sources, 2) the effectiveness of an indexing conception-based framework, and 3) the effectiveness of each of three indexing conception-based approaches (the content-oriented, the document-oriented, and the domain-oriented approaches). The experiments were conducted using a support vector machine implementation in WEKA (Witten, & Frank, 2000). The experiment results pointed out that cited works, source title, and title were as effective as the full text, while keyword was found more effective than the full text. In addition, the findings showed that an indexing conception-based framework was more effective than the full text. Especially, the content-oriented and the …

Function of the ENOD8 gene in nodules of Medicago truncatula. (open access)

Function of the ENOD8 gene in nodules of Medicago truncatula.

To elaborate on the function(s) of the ENOD8 gene in the nodules of M. truncatula, several different experimental approaches were used. A census of the ENOD8 genes was first completed indicating that only ENOD8.1 (nt10554-12564 of GenBank AF463407) is highly expressed in nodule tissues. A maltose binding protein-ENOD8 fusion protein was made with an E. coli recombinant system. A variety of biochemical assays were undertaken with the MBP-ENOD8 recombinant protein expressed in E. coli, which did not yield the esterase activity observed for ENOD8 protein nodule fractions purified from M. sativa, tested on general esterase substrates, α-naphthyl acetate, and p-nitrophenylacetate. Attempts were also made to express ENOD8 in a Pichia pastoris system; no ENOD8 protein could be detected from Pichia pastoris strains which were transformed with the ENOD8 expression cassette. Additionally, it was shown that the ENOD8 protein can be recombinantly synthesized by Nicotiana benthamiana in a soluble form, which could be tested for activity toward esterase substrates, bearing resemblance to nodule compounds, such as the Nod factor. Transcription localization studies using an ENOD8 promoter gusA fusion indicated that ENOD8 is expressed in the bacteroid-invaded zone of the nodule. The ENOD8 protein was also detected in that same zone by …

General Chemistry Topic Coverage (GCTC) comparison between community colleges and universities in the United States. (open access)

General Chemistry Topic Coverage (GCTC) comparison between community colleges and universities in the United States.

This study is based on survey responses of 224 general chemistry instructors at United States (U.S.) community colleges and universities representing 46 states. The mean values of General Chemistry Topic Coverage (GCTC) score, developed by this researcher specifically for this dissertation study as a measure of course content, were statistically analyzed. The aim of this study is to answer five research questions: (a) Is there a difference in mean GCTC scores between U.S. community colleges and four-year colleges and universities? (b) If there is a difference in mean GCTC score between the two study groups, what are the observed differences in subtopics covered between community colleges and four-year colleges and universities? (c) Considering both community colleges and universities, is there a difference in mean GCTC score between the different designated U.S. regions? (d) Considering both community college and university professors, is there a difference in GCTC score for professors with a master's degree compared to those with a doctorate?, and (e) Is there a correlation between GCTC score and the percentage of students that major in science? Results indicate that there is a statistically significant difference in course content between community colleges and universities, there is a statistically significant difference …

Acculturation and Sociocultural Influences as Predictors of Family Relationships and Body Image Dissatisfaction in African American, Hispanic American, and European American Women

Ethnic differences in etiological factors linked to body image dissatisfaction and eating disorders were examined. In addition, the interaction of acculturation and body image dissatisfaction in influencing minority women's relationships with their parents was investigated. Participants consisted of 302 undergraduates from three ethnic groups: Caucasian, Hispanic American, and African American women who were administered self-report measures. Differences were not found between the groups in body image dissatisfaction. Low self-esteem, internalization of the thin ideal, and family emphasis on weight and appearance were all related to more body image dissatisfaction for each of these groups; however, differences in degree of endorsement were also noted between the ethnic groups on these factors. Based on the interaction findings (body image x acculturation) separation from one's mother was found in the area of attitudes and emotions for the Hispanic sample but not for the African American sample on any of the parent scales. Areas for future research and implications for diagnosis and treatment of minority populations are also discussed.

Theatre teachers' attitudes toward the University Interscholastic League One-Act Play contest. (open access)

Theatre teachers' attitudes toward the University Interscholastic League One-Act Play contest.

The focus of aesthetic education is reflected in an arts curriculum designed for students to learn skills that make it possible for them to experience the world in a satisfying and meaningful manner. Incorporating aesthetics into school curriculum can be approached through the use of coordinated programs. In the state of Texas, over 1100 schools participate annually in the One-Act Play contest (OAP). The contest is governed by the University Interscholastic League (UIL), which has designed and recommended a structure in which students actively participate in the fine art of theatre. This curriculum is the roadmap for instruction that leads students to learn the value of the aesthetic. This study examines teacher and student perception in the Texas One-Act Play contest and its implications for teaching and learning the aesthetic. The qualitative data were collected through a series of interviews and observations during the spring 2006 with five schools in the north Texas area. Students and teachers at each school were interviewed. Data revealed how the goals of the UIL OAP system are being met based on teachers' practices, perceptions, and experience. Implications of the study are seen through the teachers' attitude toward winning as well as how the elements …

Scotland Expecting: Gender and National Identity in Alan Warner's Scotland (open access)

Scotland Expecting: Gender and National Identity in Alan Warner's Scotland

This dissertation examines the constructions of gender and national identity in four of Alan Warner's novels: Morvern Callar, These Demented Lands, The Sopranos, and The Man Who Walks. I argue that Warner uses gender identity as the basis for the examination of a Scottish national identity. He uses the metaphor of the body to represent Scotland in devolution. His pregnant females are representative of "Scotland Expecting," a notion that suggests Scotland is expecting independence from England. I argue that this expectation also involves the search for a genuine Scottish identity that is not marred by the effects of colonization. Warner's male characters are emasculated and represent Scotland's mythological past. The Man Who Walks suggests that his female characters' pregnancies result in stillbirths. These stillbirths represent Scotland's inability to let go of the past in order to move towards a future independent nation.

Marital satisfaction among newly married couples: Associations with religiosity and romantic attachment style. (open access)

Marital satisfaction among newly married couples: Associations with religiosity and romantic attachment style.

The marriage and family literature has identified a host of factors that contribute to a satisfactory marital union. For example, research on religious congruency has indicated that the more similar partners are in their religious beliefs the higher their reported marital satisfaction. Another construct studied in conjunction with marital satisfaction is adult attachment style. The attachment literature has consistently shown that secure couples tend to report higher marital satisfaction than couples with at least one insecure partner. The purpose of this study was to examine the combined role of religious commitment and attachment in marital satisfaction. Heterosexual couples (N = 184; 92 husbands, 92 wives) without children and married 1-5 years were administered a background information questionnaire, the Religious Commitment Inventory-10, the Dyadic Adjustment Scale, and the Experiences in Close Relationships Inventory. Results indicated that couples with congruent religious commitment reported higher marital satisfaction than couples with large discrepancies in religious commitment. Religious commitment did not mediate the relationship between attachment and marital satisfaction, but instead was found to moderate this relationship. Results of this study will benefit clinicians working in the field to help newly married couples negotiate the marital relationship.

Viability of the job characteristics model in a team environment: Prediction of job satisfaction and potential moderators. (open access)

Viability of the job characteristics model in a team environment: Prediction of job satisfaction and potential moderators.

Much of the history of management and motivation theory is rooted in the desire to understand the factors that contribute to having a satisfied workforce. Job satisfaction is the most widely studied construct in the history of industrial/organizational psychology. The job characteristics model (JCM) holds that if jobs are enriched with high levels of specific job characteristics (i.e., task significance, task variety, task identity, autonomy and feedback), employees will report higher levels of job satisfaction. While this claim enjoys wide support in studies conducted in traditional, hierarchically based organizational environments, few studies have tested the JCM in team based organizational designs. This study also evaluated possible moderating influences of growth need strength (GNS; the need for personal growth and development within the job environment) and emotional reactivity (a measure of frustration with perceived obstacles in the work environment). It was hypothesized that employees with higher levels of GNS would respond more positively (via higher job satisfaction ratings) to enriched jobs than would employees with lower levels of GNS. Alternatively, it was hypothesized that employees with lower levels of emotional reactivity would respond more positively (via higher job satisfaction ratings) to enriched jobs than would employees with higher levels of emotional …

The impact of child teacher relationship training on teachers' and aides' use of relationship-building skills and the effect on student classroom behavior. (open access)

The impact of child teacher relationship training on teachers' and aides' use of relationship-building skills and the effect on student classroom behavior.

This study examined the impact of child teacher relationship training (CTRT) on teachers' and aides' use of relationship- building skills in the classroom and the correlation between teachers' and aides' demonstration of relationship- building skills and the effect on student behavior. CTRT was modeled after Landreth and Bratton's (2006) 10-session filial therapy model titled child parent relationship therapy (CPRT) which is based on the principles and procedures of child -centered play therapy. The CPRT manual was adapted slightly for use with teachers and aides for this project. In this quasi-experimental design, 12 teacher aide dyads (n = 24) were assigned to the experimental (n = 12) or active control groups (n = 12). Children who scored in the Borderline/Clinical range on at least one scale of the Child Behavior Checklist-Caregiver/Teacher Report Form (C-TRF) at pretest qualified for the study (N = 32). During the first phase of treatment, teachers and aides participated in the equivalent of 10 training/supervision sessions consistent with the principles and procedures of CPRT. During CTRT Phase II, teachers and aides participated in 10 weeks of coaching/modeling to facilitate the use of CTRT skills in the classroom environment and continued to participate in weekly 1-hour group training/supervision …

On the subjective distinction between tenderness and joy. (open access)

On the subjective distinction between tenderness and joy.

Previous studies have shown that the experience of joy normally accompanies the experience of tenderness or love. Theorists have thus suggested that tenderness is not a distinct emotion, but rather a variety of joy. The present study explored whether it is possible to induce tenderness while inhibiting joy. Participants watched scenes designed to induce different emotions. Results showed that a scene could induce high levels of tenderness and low levels of joy if that scene also induced high levels of sadness. These findings suggest the need to reconsider theoretical assumptions regarding the distinction between tenderness and joy.

A national analysis of faculty salary and benefits in public community colleges, academic year 2003-2004.

This study provides a detailed description of full-time faculty salary and fringe benefits in US public community colleges by state and by 2005 Carnegie basic classification type for the academic year 2003-2004. This classification is used to analyze data from the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS). Further analysis clusters states into the following groupings: states with/without collective bargaining agreements, states with/without local appropriations, large megastates versus nonmegastates (using the methodology developed by Grapevine at Illinois State University), and the impact of California on the nation's salaries and fringe benefits. The analysis showed high level of variation of salaries paid by the type of community college (rural, suburban, and urban serving) in the US. The nation's average salary for full-time faculty was $52,598. Rural serving small institutions faculty salary was $18,754 or 45 % less than the nation's average. Salaries in colleges with collective bargaining agreement were higher than in colleges without collective bargaining agreements. Faculty teaching in suburban serving colleges with local taxation had the highest salaries, $61,822 within colleges with access to local support. Suburban serving multiple colleges in megastates had the highest faculty salary average, $64,540 as compared to $42,263 for rural …

The Effects of Team Dynamics Training on Conceptual Data Modeling Task Performance (open access)

The Effects of Team Dynamics Training on Conceptual Data Modeling Task Performance

Database modeling is a complex conceptual topic often taught through the use of project-based teams. One of the problems with the use of project-based teams in university courses is the determination of whether this is the most effective use of instructor and student time involvement and effort level. Therefore, this study investigated the impact of providing team dynamics training prior to the commencement of short-duration project-based team conceptual data modeling projects on individual data modeling task performance (DMTP) outcomes and team cohesiveness. The literature review encompassed conceptual data design modeling, the use of a project-based team approach, team dynamics and cohesion, self-efficacy, gender, and diversity. The research population consisted of 75 university students at a North American University (Canadian) pursuing a business program requiring an information systems course in which database design components are taught. Analysis of the collected data revealed that there was a statistically significant inverse relationship found between the provision of team dynamics training and individual DMTP. However, no statistically significant relationship was found between team dynamics training and team cohesion. Therefore, this study calls into question the value of team dynamics training on learning outcomes in the case of very short duration project-based teams involved in …

Effectiveness of Child-Centered Play Therapy with Japanese Children in the United States

This study explored the use of child-centered play therapy (CCPT) as a culturally responsive intervention and a prevention treatment method for the psychosocial well-being of Japanese children in the United States. In light of the demand for the evidence-based therapeutic treatment for children as well as the need to conduct multicultural research without ignoring within-group differences, this study was composed of two research methodologies; quantitative research design and individual analysis. Single-group repeated measures ANOVA was utilized for the group analysis and linear regression was employed for individual analysis in addition to qualitative data obtained through parent feedback and the researcher's observation of play therapy sessions. The participating children received a total of eight CCPT sessions. The impact of CCPT was measured by a decrease in a child's behavioral problems perceived by a parent measured by scores of the Internalizing Problems, Externalizing Problems and Total Problems on the Child Behavioral Checklist and a reduction of parent-child relationship stress manifested in the Child Domain, Parent Domain and Total Stress Score of the Parenting Stress Index. Data from a total of the four assessment points; the baseline, pretest, second assessment, and third assessment, was gathered for use in the analysis. A total of …

Improving self-efficacy in college students: A modified adventure therapy program. (open access)

Improving self-efficacy in college students: A modified adventure therapy program.

Adventure therapy employs a technique in which therapists use controlled amounts of stress to bring about change in the behavior of clients. One of the domains in which adventure therapy reports improvement is that of self-efficacy. Perceived self-efficacy is the belief that individuals have in their ability to overcome and change their situation in life. This study examines the effect of a modified adventure therapy program on the perceived self-efficacy of college students who were enrolled in an Outdoor Pursuits course at a major metropolitan university. Students received 16 weeks of outdoor adventure therapy programming that culminated in a voluntary weekend camping trip. The students were administered the General Self-Efficacy (GSE) scale on the second day of class to determine a baseline level of self-efficacy to be compared to the posttest completed on the last day of class. The study examined 3 consecutive semesters of archival data collected by the researcher while instructing the course. Fifty-six participants across the 3 semesters were usable for data analysis. The results show there is a significant difference between students' level of perceived self-efficacy from pre- to posttest, and no difference in the effect on gender, classification of students, or the participation of the …

Mediation on XQuery Views (open access)

Mediation on XQuery Views

The major goal of information integration is to provide efficient and easy-to-use access to multiple heterogeneous data sources with a single query. At the same time, one of the current trends is to use standard technologies for implementing solutions to complex software problems. In this dissertation, I used XML and XQuery as the standard technologies and have developed an extended projection algorithm to provide a solution to the information integration problem. In order to demonstrate my solution, I implemented a prototype mediation system called Omphalos based on XML related technologies. The dissertation describes the architecture of the system, its metadata, and the process it uses to answer queries. The system uses XQuery expressions (termed metaqueries) to capture complex mappings between global schemas and data source schemas. The system then applies these metaqueries in order to rewrite a user query on a virtual global database (representing the integrated view of the heterogeneous data sources) to a query (termed an outsourced query) on the real data sources. An extended XML document projection algorithm was developed to increase the efficiency of selecting the relevant subset of data from an individual data source to answer the user query. The system applies the projection algorithm …

The Effects of Trade Liberalization Policies on Human Development in Selected Least Developed Countries

This dissertation examines the effects of trade liberalization policies (represented by membership in the General Agreement on Tariffs and Trade/World Trade Organization on selected Least Developed Countries' (LDCs) human development (represented by the Human Development Index). In this dissertation, General Agreement on Tariffs and Trade (GATT) and World Trade Organization (WTO) policies are theorized to have two distinct types of effects: their direct effect and their indirect effect. Two questions are focused on: first, what is the effect (total, direct and indirect) of WTO policies on human development for selected LDCs? Second, what is the effect (total, direct and indirect) of WTO policies on human development for selected developing/developed countries (i.e. non-LDCs) holding economic development constant? Using the dependency theory of development as a theoretical basis, this dissertation examines the assumptions of modernization-theory-based policies as expressed in trade liberalization policies (i.e. the implementation of comparative advantage and now market fundamentalism) with world-system analysis techniques. To examine these questions, four panel regression models are constructed to measure the total, direct and indirect effects of WTO policies during the near-term (1998-2003) and during a longer historical term (1975-2000). The data for the analyses are taken from seven different sources of international data. …
