Teachers of students with emotional/behavioral disorders (E/BD) find that myriad concerns for effective teaching (e.g., salaries, increased paperwork, classroom management) challenge their ability to meet personal and professional needs. The push for certified teachers and limited training to work with students with special needs create stressors that can prohibit effective teaching in the workplace. Teacher moral drops and half of newly hired employees leave the profession. Equally important, student outcomes are affected. Demographic information, program practices, and commitment information from special education teachers across the country were examined in this study. These areas of study helped to determine the best indicators for teacher job satisfaction and barriers that threaten satisfactory working conditions. An online survey was designed to capture 29 areas to explore qualifications and working environments for these teachers. Of the 600 targeted teachers, 332 individuals participated in Likert-like scales to determine their degree of satisfaction or dissatisfaction for working conditions, use of intervention strategies, and areas of commitment. Closed-ended and multiple-choice questions were used. Descriptive analyses and tables aided in understanding this study. The resulting factors indicated that, although some respondents pointed to job dissatisfaction within the subset of questions, participants who worked for more than 6 years …

The purpose of this study was to explore the factors influencing information and computing technology (ICT) adoption for Omani faculty members from a framework of Rogers' theory of diffusion of innovation. Three hundred Omani faculty members from Sultan Qaboos University (SQU) participated in the study. The survey consisted of five parts: (a) an 18-item questionnaire on ICT uses and skills, (b) a 1-item questionnaire on adopter category, (c) a 44-item self-constructed questionnaire on perception of barriers to adopting ICT, (d) a 50-item questionnaire on ICT attributes adapted from Moore and Benbasat, and (e) a 15-item questionnaire on demographic and job-related variables. Descriptive statistics indicated that the faculty members overall used ICT at the "Sometimes" level and had ICT skills at the "Intermediate" level. The most frequently used and skillful ICT functional areas were Website browsing, Internet search engine, and word processing. One-way ANOVAs found significant group differences of ICT uses and skills, perception of barriers, and perception of ICT attributes in the category of adopter. Early adopters used ICT more, had higher ICT skills, perceived fewer barriers in the adopting process, and recognized higher values of ICT attributes than later adopters did. Multiple regression analysis showed the level of ICT …

The gas phase reactions of atomic chlorine with hydrogen sulfide, ammonia, benzene, and ethylene are investigated using the laser flash photolysis / resonance fluorescence experimental technique. In addition, the kinetics of the reverse processes for the latter two elementary reactions are also studied experimentally. The absolute rate constants for these processes are measured over a wide range of conditions, and the results offer new accurate information about the reactivity and thermochemistry of these systems. The temperature dependences of these reactions are interpreted via the Arrhenius equation, which yields significantly negative activation energies for the reaction of the chlorine atom and hydrogen sulfide as well as for that between the phenyl radical and hydrogen chloride. Positive activation energies which are smaller than the overall endothermicity are measured for the reactions between atomic chlorine with ammonia and ethylene, which suggests that the reverse processes for these reactions also possess negative activation energies. The enthalpies of formation of the phenyl and β-chlorovinyl are assessed via the third-law method. The stability and reactivity of each reaction system is further rationalized based on potential energy surfaces, computed with high-level ab initio quantum mechanical methods and refined through the inclusion of effects which arise from the …

This research study addressed the nutritional beliefs and habits of African-American parents of children aged 3 to 6 years old. Both quantitative and qualitative data collection methods were employed. Quantitative data was collected via the Comprehensive Feeding Practices Questionnaire as well as a demographic questionnaire. Qualitative data was collected from oral interviews conducted by the researcher. Seventy-five parents or guardians participated in the study. Findings for the research questions revealed the participants' beliefs about nutrition directly correlated with food they provided for their children and most believed nutrition rather than genetics played a role in their child(ren)'s weight. Furthermore, parents from lower income families consumed more home cooked meals per week and those with higher incomes did not consume more fast food per week. Food intake restriction and control in feeding was similar among all participants, regardless of restriction and control in feeding was similar among all participants, regardless of education or income level. Suggestions for future research were included.

Prescription drug direct-to-consumer advertising (DTCA) has been a subject of controversy in recent years. Though government regulations require equivalent prominence of risks and benefits, there is concern about the ability of consumers with limited health literacy to fully comprehend the risks and benefits associated with drug use. Evaluating the images in DTCA is important because individuals may rely on the visual message if the wording is overly complex. Using semiotics, this study aims to evaluate whether there is functional equivalence in the presentation of risk and benefit information in prescription drug direct-to-consumer television advertising. A new analytical method is created and used to assess the consistency between the messages contained in the voice track, the primary visual images, and the superscript/ subscript text. The results indicate that risk and benefit messages in this DTCA sample lack functional equivalence. However, it is important to properly frame these findings as the study does not evaluate viewer comprehension of the various message structures.

This study explores six utopias by female authors written at the turn of the twentieth century: Mary Bradley Lane's Mizora (1881), Alice Ilgenfritz Jones and Ella Merchant's Unveiling Parallel (1893), Eloise O. Richberg's Reinstern (1900), Lena J. Fry's Other Worlds (1905), Charlotte Perkins Gilman's Herland (1915), and Martha Bensley Bruère's Mildred Carver, USA (1919). While the right to vote had become the central, most important point of the movement, women were concerned with many other issues affecting their lives. Positioned within the context of the late nineteenth century women's rights movement, this study examines these "sideline" concerns of the movement such as home and gender-determined spheres, motherhood, work, marriage, independence, and self-sufficiency and relates them to the transforming character of female identity at the time. The study focuses primarily on analyzing the expression of female historical desire through utopian genre and on explicating the contradictory nature of utopian production.

Previous research indicates that stressors experienced by a family, the perceived level of burden assigned by the family to the stressor, and the utilization of resources predict family functioning. The current study utilized a nationally representative sample of families of children with autistic disorder to determine if previously proposed models of family functioning accurately conceptualized family functioning within a representative sample. Structural equation modeling was utilized to test the double ABCX and the linear ACBX models of family functioning. With slight modifications, the double ABCX model was supported, thus indicating that pileup of stressors, perception of burden, and utilization of resources each have unique predictive ability for family functioning, with perception of burden demonstrating the highest amount of predictive ability. Results, implications, and limitations of the study are discussed.

As selection pressures exist for not only adults, but for every life history stage, it is important to understand how environmental factors shape developing animals. Despite the significance placed on aquatic hypoxia as a driving force in the evolution of air breathing, this is the first known study to examine the effects of hypoxia on cardio-respiratory ontogeny of an air breathing fish. Blue gouramis are obligatory air breathing fish that possess a labyrinth-like structure that serves as the air breathing organ. Gouramis were reared for up to 90 d in normoxia or hypoxia, and morphological and physiological development was observed. Hypoxic larvae had increased lamellar and labyrinth organ surface areas. Bradycardia and increased gill ventilation rates were observed when larvae from either rearing group were briefly exposed to hypoxia. Hypoxic larvae also showed a reduced heart rate and gill ventilation rate in the absence of a hypoxic stimulus, possibly indicative of a more comprehensive, long-term respiratory plasticity. The similarity of routine oxygen consumption between rearing groups suggests that metabolic demand did not change for hypoxic larvae, but that they were more efficient at oxygen acquisition. This is further supported by increased resistance time of hypoxic gouramis to extreme hypoxia. The …

Fetal programming results from stressors during fetal development and may influence the occurrence of disease later in life. Maternal nutritional status and/or environment can affect renal development by inducing limited nephron endowment at birth, which results in diseases such as hypertension and coronary heart disease in mammals. Birds are likely to be effective models for this process because, like mammals, they have high pressure cardiovascular systems, mammalian-type nephrons and are homeothermic. This project uses the chicken embryo to explore physiological responses of disrupted hydration state thereby providing insights into renal fetal programming. Under normal conditions the chorioallantoic membrane (CAM) and developing avian kidney work in unison to ensure a proper balance of ions and water within the egg. White leghorn chicken eggs were incubated at 37.5oC±0.5oC and either <35%, 55-60% (normal) or >85% relative humidity. Amniotic fluid serves as the drinking source for the embryo late in development; its composition is important to salt and water homeostasis. High amniotic fluid osmolality increased the blood osmolality for embryos exposed to low humidity incubation thereby indirectly influencing the renal developmental program of the embryos from this group. Indeed estimated filtering capacity was doubled in the low humidity group (6.77 ± 0.43 mm3) …

The purpose of this study was to examine data from the Early Childhood Longitudinal Study: Kindergarten Class of 1998-99 (ECLS-K) report, identify questions and statements that correlate to the dimensions of professional learning communities (PLCs), and determine the effect PLCs have on student achievement based on the ECLS-K data. In addition, the rationale for doing this research was to measure growth in student achievement over time. A multilevel growth model was used for this research. Univariate analysis was conducted in order to reveal frequencies and percentages associated with teacher responses. Bivariate analysis was applied in order to determine the inter-correlations between the fourteen variables. Once the inter-correlations were determined from the bivariate analysis, principal component analysis was applied in order to reveal the theoretical relationship between the variables. Through the use of principal components a set of correlated variables is transformed into a set of structure coefficient: support and collaborative. Finally, a multilevel growth model was used in order to determine the effect that each variable within the support and collaborative structure coefficients had on student achievement over time. This study revealed a number of variables within the ECLS-K report that correspond to the dimensions of PLCs have a statistically …

At the University of North Texas, and as per the Council for Accreditation of Counseling and Related Educational Programs (CACREP) standards, masters students in counselor training are required to choose a personal theoretical approach to the counseling process. The purpose of this study was to investigate an experimental counseling theory identification procedure compared to the traditional procedure of helping students identify a personal theory of counseling. The investigation assessed the effect on 1) counselor self-report of confidence in theoretical orientation selection/identification, and 2) the degree to which a student consistently identifies, conceptualizes and utilizes a particular counseling theoretical approach. Volunteer participants (n=35) were recruited from three sections of COUN 5660 and were randomly drawn to group assignment within each class. The experimental condition focused on exploration of personal beliefs related to human nature, maladjustment and the nature of change as a basis for theory selection. The comparison group received the standard theory selection activities. The TCQ and TOPS-R were used to examine the effect of treatment and were administered at three points of time. Data was analyzed using a split plot ANOVA to examine group differences, changes across time, and the possible interaction of change with group membership. Statistical and …

This study empirically examines the impact of IT capability on firms' performance and evaluates whether firms' IT capabilities play a role in improving employee capability, customer value, customer satisfaction, and ultimately business performance. The results were based on comparing the business performance of the IT leader companies with that of control companies of similar size and industry. The IT leader companies were selected from the Information Week 500 list published annually from 2001 to 2004. For a company to be selected as IT leaders, it needed to be listed at least twice during the period. Furthermore, it had to be listed in the American Customer Satisfaction Index (ACSI) so that its customer satisfaction level could be assessed. Standard & Poor's Compustat and the ACSI scores were used to test for changes in business performance. The study found that the IT leaders had a raw material cost measured by cost-of-goods-sold to sales ratio (COGS/S) than the control companies. However, it found no evidence that firms' IT capability affects employee capability, customer value, customer satisfaction, and profit. An important implication from this study is that IT becomes a commodity and an attempt to gain a competitive advantage by overinvesting in IT may …

Despite the widespread recommendation that schools "collaborate" with parents, little is found in the literature to elaborate on what this term or the common synonym "partnership" means, and further, how schools can invite diverse parental contributions to the table of educational discourse. The current study looks to contribute to the literature by analyzing the parent participation discourse in one community elementary school, utilizing critical discourse analysis and ethnographic observations. The findings reveal both school and parents' conceptions of the parents' partnership role as ancillary to that of the school's and the subsequent lack of true collaboration so advocated by the literature. Implications arise from this analysis which calls into question the examples of "collaboration" found in the literature, given the lack of theorizing regarding what collaboration inside of parent participation means. Contributions may shed light on the unintentional inequality of diverse parents in an effort toward true collaboration utilizing both the European American, middle class contributions of the educational institution alongside those of non-mainstream parents in creating an authentic educational atmosphere for diverse students.

Research has been conducted on Francis Poulenc and his prominent 20th century sonata for brass instruments. Poulenc and members of the French compositional collaboration known as Les Six have all been subjects of research. Francis Poulenc's Sonata for Horn Trumpet and Trombone is a crucial piece in the development of brass chamber music during the 20th century. As one of the first works written for modern brass instruments, it demonstrates a highly crafted compositional style representative of Poulenc's early period. Research includes background and historical significance of the Sonata, analysis of form and compositional techniques, biographical information on Francis Poulenc and the members of Les Six and a section on implications for the performance of the work. This study is necessary due to the lack of research available for the piece especially considering its relevance to the development of brass chamber music. This study explores the compositional style of Francis Poulenc and his contribution to the brass ensemble repertoire.

Traditional Public Health decision-support can benefit from the Web and social media revolution. This dissertation presents approaches to mining social media benefiting public health epidemiology. Through discovery and analysis of trends in Influenza related blogs, a correlation to Centers for Disease Control and Prevention (CDC) influenza-like-illness patient reporting at sentinel health-care providers is verified. A second approach considers personal beliefs of vaccination in social media. A vaccine for human papillomavirus (HPV) was approved by the Food and Drug Administration in May 2006. The virus is present in nearly all cervical cancers and implicated in many throat and oral cancers. Results from automatic sentiment classification of HPV vaccination beliefs are presented which will enable more accurate prediction of the vaccine's population-level impact. Two epidemic models are introduced that embody the intimate social networks related to HPV transmission. Ultimately, aggregating these methodologies with epidemic and social network modeling facilitate effective development of strategies for targeted interventions.

The semiconducting silicides offer significant potential for use in optoelectronic devices. Full implementation of the materials, however, requires the ability to tailor the energy gap and band structure to permit the synthesis of heterojunctions. One promising approach is to alloy the silicides with Ge. As part of an investigation into the synthesis of semiconducting silicide heterostructures, a series of β-Fe(Si1−xGex)2 epilayer samples, with nominal alloy content in the range 0 < x < 0.15, have been prepared by molecular beam epitaxy on Si(100). I present results of the epitaxial and crystalline quality of the films, as determined by reflection high-energy electron diffraction, Rutherford backscattering spectroscopy, and double crystal x-ray diffraction, and of the band gap dependence on the alloy composition, as determined by Fourier transform infrared spectroscopy. A reduction in band gap was observed with increasing Ge content, in agreement with previous theoretical predictions. However Ge segregation was also observed in β-Fe(Si1−xGex)2 epilayers when x > 0.04. Osmium silicide films have been grown by molecular beam epitaxy on Si(100). The silicides have been grown using e-beam evaporation sources for both Os and Si onto Si(100) substrates at varying growth rates and temperatures ranging from 600-700ºC. The resulting films have been …

Considerable research has demonstrated a link between thoughts of revenge, or vengeful rumination, and the development of posttraumatic stress disorder (PTSD) symptoms, particularly in situations involving interpersonal trauma. Personality factors have been related to both vengefulness and PTSD. No study to date has simultaneously examined the unique contributions of vengefulness and personality factors in the development of PTSD symptoms. Therefore, the present study addressed these questions in an inpatient sample by comparing contributions of the Big Five personality factors and vengeful rumination to the development of PTSD symptoms through correlation, hierarchical regression, and omnibus regression analyses. Results showed that Neuroticism predicted PTSD symptoms better than other personality factors, that Neuroticism and Agreeableness predicted vengeful rumination in opposite directions, and that personality factors and vengeful rumination each added unique variance in the prediction of PTSD symptoms. Future directions and implications are discussed.

The poet of this cycle, Sydney Vernon Petersen, was a man who faced great adversity during Apartheid. The title of this cycle, Alleenstryd, is an Afrikaans term for 'a struggle alone.' Petersen was of mixed heritage or "Coloured" and born in South Africa in 1914. He died in 1987. His most important works in Afrikaans poetry were published between 1948 and 1965. This cycle specifically focuses on the relationship between the poet and his community, the isolation he endured within that community, the depths of despair he felt and how he overcame those obstacles to finally achieve a sense of self-worth. This group of poems, first published as an anthology by Tafelberg Press in 1979, became the source of inspiration for the composer Hendrik Hofmeyr. The purpose of this research is to identify the significant social, political and musical influences on the composer which contributed to the composition of Alleenstryd (1996), especially the significance of his self-imposed exile. Also, the Afrikaans language, a derivative of 17th century Dutch, is a language dear to its speakers but not widely accessible or familiar to most other nations. Hopefully this research will provide more information and make the language, its composers and the …

A comparative evaluation framework of instructional interventions for implementation of online training for public library staff would enable a better understanding of how to improve the effectiveness, efficiency and efficacy of training in certain training environments. This dissertation describes a quasi-experimental study of a two-week, asynchronous online training course that was provided at four levels of instructional intervention to public library staff in the United States. The course content addressed the complex issues of difficult patron policy development and situational coping techniques. The objective of the study was to develop and demonstrate a theoretically grounded, evidence-based impact evaluation framework. The framework was used to assess the relative impact of an online course for public librarians at four levels of instructional intervention. The researcher investigated the relationships between the type of e-Training instructional interventions and the short- and long-term impacts on participants' knowledge, self-efficacy, and workplace performance. The study used a longitudinal, quasi-experimental design that included a pretest, posttest and three-month delayed posttest with follow-up survey. 194 participants completed all three phases of the study. The evaluation tools measured course content related knowledge and self-efficacy at all three phases (pretest, posttest, and delayed posttest) and assessed workplace application of training at …

The presence of cognitive deficits in obstructive sleep apnea (OSA) is well-documented. Specifically, short- and long-term memory, attention/vigilance, and executive function (e.g. processing speed, mental flexibility, and problem solving) are affected. Cognitive deficits in aging occur in similar areas (i.e., memory and processing speed). Given that a greater percentage of older adults experience sleep-disordered breathing as compared to middle-aged adults, it is possible that OSA may account for some of the deficits typically attributed to aging. This study investigated this hypothesis by comparing middle-aged and older adults with and without OSA on computer-based measures of cognitive performance. No effect of OSA or an interaction between OSA and age on cognitive function was found; an effect of age on processing speed, distinguishing stimuli rapidly, attention, spatial ability/mental flexibility, and both working memory and short-term visual memory was found. This study also explored whether or not cognitive function may be improved in persons with OSA by re-assessing those participants one month after treatment. An effect of treatment on improvements on processing speed, distinguishing stimuli rapidly, mental flexibility, and short term memory was found. Overall, findings reflect the ability of treatment to improve cognitive function among OSA patients, regardless of lack of deficits …

Safety is an important aspect of ethical, socially responsible logistics. Current U.S. motor carrier (MC) safety research topical coverage includes the effects of individual and environmental influences, carrier safety management, and regulatory compliance on carrier safety and driver fatigue/safety performance. Interestingly, little research on the subject of truck drivers' safety attitudes and behaviors exists and the underlying decision-making processes that guide drivers' safety-related behaviors have received little attention. Furthermore, researchers have not provided an integrated framework that explains individual, organizational, and regulatory factors' impact on drivers' safety decision-making and performance. Truck drivers' safety judgments, decisions, and actions must adhere to societal safety norms. To that end, ethical decision-making theory that draws from the deontological and teleological traditions in moral philosophy provides a theoretical foundation and integrated framework necessary to better understand drivers' safety decision-making processes. The current research sought to determine how drivers rely on safety norms and perceived consequences in forming safety judgments and behavioral intentions. Furthermore, the study was designed to explore how various factors (i.e., individual, organizational, and regulatory) influence drivers' safety decision-making processes. Specifically, the study sought to answer the broad question, "How do commercial motor vehicle drivers make safety-related decisions, and how do individual, organizational, …

The questions guiding this research seek to discover the factors that affect high school math course completion and college readiness in a Texas suburban public school district. The first research question examines the relationship between 8th grade completion of Algebra I and high school mathematics course taking patterns and college readiness. The second question evaluates the relationship between race, gender, socioeconomic status and enrollment in the Advancement Via Individual Determination (AVID) program to college math readiness and high school mathematics course completion. Participants included 841 high school graduates of the class of 2006; 76% of the graduates were White, 15% Hispanic and 7% African American. Twenty-three percent of students were economically disadvantaged and 46% of students completed Algebra I in 8th grade. Chi-square, Cramer's V, and multiple regression were conducted to evaluate possible relationships between variables. The Chi-square and Cramer's V showed statistically significant (p<.05) relationships between 8th grade algebra completion and both college readiness and high school math course completion. A significant statistical relationship was also found between college readiness and each of the independent variables, ethnicity, economic status, completion of 8th grade algebra and enrollment in AVID. The number of math courses completed in high school was statistically …

This study was conducted on-site in Istanbul, Turkey, to determine the effects that mass media has on citizens' perceptions about fear of crime, in particular, and fear, in general. Specifically, the study was designed to (1) determine the tendency of citizens' media consumption, (2) determine the level of fear of crime among Turkish citizens, (3) establish the effect of media on citizens' fear of crime, and (4) determine if gender, age, educational level, neighborhood, and monthly income have an independent effect on fear of crime. To achieve this purpose, after administering a survey in Istanbul, the researcher collected appropriate data and then utilized regression analysis to examine the relationship between media variables and fear of crime. A survey consisting of three parts was administered to 545 Turkish citizens over the age of 18 who currently reside in Istanbul, Turkey. In Part I of the survey, respondents were asked to identify their trends in relation to media consumption, and in Part II respondents were asked to report their feelings about fear of crime. Finally, Part III consisted of socio-demographic characteristics including gender, age, marital status, level of education, and income. The media variables used for this study were, general TV viewing, …

With the world amidst globalization and economic flux affecting business, industry, and communities the need to work together becomes increasingly important. Higher education serves an important role in developing the individual teaming capabilities of the workforce. This environment is the time and place - opportunity for student personnel to develop these capabilities. This multiple case study utilized the analysis phase (learner, setting and job) of an instructional design model to analyze learner characteristics, the higher education environment/undergraduate experience, and the job/skills associated with individual teamwork knowledge, skills, and abilities of students from a senior cohort of the TRiO - SSS Project at a public student-centered research institution. The results yielded themes to promote the development of target populations individual teamwork KSAs which should increase their readiness to meet the teaming demands of today's employers. With an engaging undergraduate experience, inclusive of interaction with faculty members and collaborative learning with their peers, structured opportunities to practice individual teamwork KSAs in a work setting or internship, these underrepresented students may be an asset that is needed to meet the global workforce needs and fill civic capacities in their home communities.
