This study has two purposes. First is to dispel myths that there are no residence halls at community colleges. Second is to discuss the ways in which these residence halls are administered, the amenities offered to students, the benefits of residence halls, and their future in community colleges. The study is based upon the Katsinas, Lacey and Hardy 2004 classifications and divides community colleges into 7 categories: Urban multi campus, Urban single campus, Suburban multi campus, Suburban single campus, and Rural small, medium and large. Included in the study are tables of data received from an original survey sent to 232 community college CEOs who reported to the US Department of Education that they had residence halls at their campus. The results indicate that a significant number of community colleges with residence halls exist, particularly at rural community colleges, that they bring significant financial gain to the colleges, and they append numerous benefits to students and to student life at these colleges. Residence halls are housed in divisions of student services and directed by experienced student affairs professionals. The study concludes with recommendations for policy as well as practice, the most important of which calls for more accurate data collection …

This study examined allied health and nursing career and technical education (CTE) teacher beliefs and attitudes about reading. Since beliefs and attitudes influence the way teachers teach, it is important to understand what those beliefs and attitudes are, especially in relationship to reading in subject matter classrooms. One hundred twelve individuals responded to a written survey concerning their attitudes and beliefs about reading. A four-factor solution was achieved with a principal components factor analysis. A significant number of variables were associated with the factor labeled Reading Apathy, which appears to be indicative of the condition known as aliteracy among faculty who participated in the study. Professional development activities grounded in novice-to-expert theory are suggested as a way of overcoming the phenomenon. Recommendations for future research involve a more detailed study to further characterize the condition of aliteracy and its impact on student learning.

The purpose of this study was to develop an effective formal instrument to assess the Adlerian personality priorities. The development of the Allen Assessment for Adlerian Personality Priorities, AAAPP, seeks to provide a strong comparability to assessing the Adlerian construct of personality priorities as the counselor interview. One hundred and seven participants were given the 1st administration of the AAAPP, Social Interest Scale and a demographic survey. Sixty-four participants completed a 2nd administration of the AAAPP two weeks later. Twenty participants experienced a counseling interview following the 2nd administration. The methods used to evaluate the validity and effectiveness of the AAAPP included: face validity, predictive validity, construct validity, test-retest reliability, multiple regression, Guttman split-half reliability and the Spearman Brown reliability.

The purpose of this study was to determine if character education programs impact the suspension rates of students from regular instructional public elementary schools in Texas. The data was also examined to determine if the number of years since a school's implementation of a character education program has an impact on the effectiveness of the programs as measured by the suspension rates of students from school. Finally, the study sought to determine if the socio-economic status of the schools has an impact on the effectiveness of character education programs as measured by the student suspension rates. A random sample of 135 regular instructional public elementary schools in Texas was collected. The principal of each school completed a questionnaire that was used to sort schools into three groups: schools with "direct" character education programs, schools with "indirect" character education programs, and schools that have implemented no type of character education program. A two-year history of suspensions was obtained for each school. The data was analyzed using one-way and two-way ANOVAs. The results of the analyses indicated that the implementation of character education programs, no matter what type, did not produce statistically significant differences in student suspension rates from school. Furthermore, the …

In response to compatible rhizobia, leguminous plants develop unique plant organs, root nodules, in which rhizobia fix nitrogen into ammonia. During nodule invasion, the rhizobia gain access to newly divided cells, the nodule primordia, in the root inner cortex through plant-derived cellulose tubes called infection threads. Infection threads begin in curled root hairs and bring rhizobia into the root crossing several cell layers in the process. Ultimately the rhizobia are deposited within nodule primordium cells through a process resembling endocytosis. Plant host mechanisms underlying the formation and regulation of the invasion process are not understood. To identify and clone plant genes required for nodule invasion, recent efforts have focused on Medicago truncatula. In a collaborative effort the nodulation defect in the lin (lumpy infections) mutant was characterized. From an EMS-mutagenized population of M. truncatula, two non-allelic mutants nip (numerous infections with polyphenolics) and sli (sluggish infections) were identified with defects in nodule invasion. Infection threads were found to proliferate abnormally in the nip mutant nodules with only very rare deposition of rhizobia within plant host cells. nip nodules were found to accumulate polyphenolic compounds, indicative of a host defense response. Interestingly, nip was also found to have defective lateral root …

The influence of charge heterogeneity in nanoparticles such as montmorillonite layered silicates (MLS) and hybrid systems of MLS + carbon nanotubes was investigated in cured and uncured epoxy. Epoxy nanocomposites made with cation-exchanged montmorillonite clay were found to form agglomerates near a critical concentration. Using differential scanning calorimetry it was determined that the mixing temperature of the epoxy + MLS mixture prior to the addition of the curing agent critically influenced the formation of the agglomerate. Cured epoxy samples showed evidence of the agglomerate being residual charge driven by maxima and minima in the concentration profiles of thermal conductivity and dielectric permittivity respectively. A hybrid nanocomposite of MLS and aniline functionalized multi walled nanotubes indicated no agglomerates. The influence of environmentally and process driven properties on the nanocomposites was investigated by examination of moisture, ultrasound, microwaves and mechanical fatigue on the properties of the hybrid systems. The results point to the importance of charge screening by adsorbed or reacted water and on nanoparticulates.

This dissertation focuses on the chemistry, detection, and control of metals and metal contaminants during manufacturing of integrated circuits (ICs) on silicon wafers. Chapter 1 begins with an overview of IC manufacturing, including discussion of the common aqueous cleaning solutions, metallization processes, and analytical techniques that will be investigated in subsequent chapters. Chapter 2 covers initial investigations into the chemistry of the SC2 clean - a mixture of HCl, H2O2, and DI water - especially on the behavior of H2O2 in this solution and the impact of HCl concentration on metal removal from particle addition to silicon oxide surfaces. Chapter 3 includes a more generalized investigation of the chemistry of metal ions in solution and how they react with the silicon oxide surfaces they are brought into contact with, concluding with illumination of the fundamental chemical principles that govern their behavior. Chapter 4 shows how metal contaminants behave on silicon wafers when subjected to the high temperature (≥ 800 °C) thermal cycles that are encountered in IC manufacturing. It demonstrates that knowledge of some fundamental thermodynamic properties of the metals allow accurate prediction of what will happen to a metal during these processes. Chapter 5 covers a very different but …

The purpose of this study is to determine whether the style of a user interface (i.e., its look and feel) has an effect on the usability of a synchronous computer supported cooperative work (CSCW) environment for delivering Internet-based collaborative content. The problem motivating this study is that people who are located in different places need to be able to communicate with one another. One way to do this is by using complex computer tools that allow users to share information, documents, programs, etc. As an increasing number of business organizations require workers to use these types of complex communication tools, it is important to determine how users regard these types of tools and whether they are perceived to be useful. If a tool, or interface, is not perceived to be useful then it is often not used, or used ineffectively. As organizations strive to improve communication with and among users by providing more Internet-based collaborative environments, the users' experience in this form of delivery may be tied to a style of user interface look and feel that could negatively affect their overall acceptance and satisfaction of the collaborative environment. The significance of this study is that it applies the technology …

This study analyzed test scores of economically disadvantaged students who attended two elementary schools implementing different types of Title I models from 1999-2001. Test scores from the Texas Assessment of Academic Skills (TAAS), the Iowa Test of Basic Skills (ITBS) and the Stanford Achievement Test (SAT-9) were analyzed. One school implemented the targeted assistance model (less than 50% poverty), which focused resources on students were identified as failing or at risk of failing. The other a schoolwide model (95% poverty), which used resources to help all students in a school regardless of whether they ware failing, at risk of failing, or economically disadvantaged. The quantitative approach was used with a causal comparative design. A cohort of continuously enrolled students was identified for the TAAS (n=169 and 189) and the ITBS/SAT-9 (n=49 and 87). Descriptive statistics such as the frequency, mean, and standard deviation, were used to measure differences on the Texas Learning Index (TLI) for the TAAS, and Normal Curve Equivalent (NCE) on the ITBS/SAT-9. Analysis of covariance (ANCOVA) was used to partially adjust for preexisting differences among the groups and because randomization was not possible. The independent variable was type of Title I model, targeted assistance or schoolwide. The …

This dissertation proposes to delineate the criteria for determining the constitutionality of public school dress codes based on an examination of relevant case law. The study addresses the following underlying questions: (1) Do students have a constitutional right to freedom of choice regarding their personal dress and grooming in public schools? (2) If so, what is the origin of the right? (3) What justification does a school district need in order to intrude upon the right? (4) Does the extent to which there is a right, and that it is accorded support by the judiciary, depend on the student's age and grade level? (5) What do state statutes say about dress codes and uniforms? (6) Do state statutes comport with the circuit courts' rulings in the various jurisdictions? The first part of Chapter I examines the purpose of school uniforms as set forth in relevant educational literature and commentary. The second part of the chapter examines empirical evidence on the effects of dress codes and uniforms. Chapter II addresses the first three questions listed above concerning students' right to choice in personal dress, the origins of such a right, and the justification required for a school to intrude upon this …

Mid-level leaders are often expected to implement employee empowerment initiatives, yet many do not have a clear understanding of how to empower employees. To address this issue, a model of empowering leadership was developed. The model presents specific, actionable behaviors that a leader should perform in order to empower employees. The model comprises 13 factors built around the areas of ability, accountability, and authority. First, leaders must ensure employees have the ability to be empowered. To do so, they must (a) build employee organizational knowledge, (b) provide access to pertinent information, (c) assure employees have the necessary skill set, and (d) identify and provide needed resources. Second, leaders must create systems of accountability for employee outcomes by (e) setting a standard of continuous improvement, (f) recognizing and rewarding good work, (g) regularly evaluating employee efforts, and (h) providing continuous feedback on employee efforts. Third, leaders should provide employees with the authority to be empowered by (i) serving as advocates of employee efforts, (j) providing an environment that is conducive to empowerment, (k) setting a clear and consistent direction to guide employee efforts, and (l) building systems and structures to support employee empowerment. The thirteenth factor of the model is a …

In this dissertation, we study the dynamics, fractal geometry and the topology of the Julia set of functions in the family H which is a set in the class S, the Speiser class of entire transcendental functions which have only finitely many singular values. One can think of a function from H as a generalized expanding function from the cosh family. We shall build a version of thermodynamic formalism for functions in H and we shall show among others, the existence and uniqueness of a conformal measure. Then we prove a Bowen's type formula, i.e. we show that the Hausdorff dimension of the set of returning points, is the unique zero of the pressure function. We shall also study conjugacies in the family H, perturbation of functions in the family and related dynamical properties. We define Perron-Frobenius operators for some functions naturally associated with functions in the family H and then, using fundamental properties of these operators, we shall prove the important result that the Hausdorff dimension of the subset of returning points depends analytically on the parameter taken from a small open subset of the n-dimensional parameter space.

The purpose of this study was to examine the usefulness of electronic-based questionnaires as a tool to gather data from field supervisors in the medical profession at various military bases. The study compared the response effects of an electronic evaluation questionnaire with the traditional method of paper-based questionnaires in gathering Level 3 data. The number of returns affects the amount of information available to the course personnel in creating a viable program that ensures the success of service members entering the occupational field and, ultimately, affecting the number of service members who remain beyond their first enlistment. The return rate and amount of missing data were tracked. Supervisors of graduates of a medical program who had observed service members for a minimum of 4-months were participants in the study. The z-test for comparing two proportions was used to determine significance of the study at the .05 level. Findings indicate that there was a significant difference in return rates and the amount of missing data when using the electronic format. Based on this study, the electronic-based questionnaire as a data-gathering tool provided a higher number of returns in a quicker time frame with fewer missing data in the technical training environment. …

This study examines the impact of Statements of Financial Accounting Standards No. 141 and No. 142 (hereafter SFAS 141, 142) on the characteristics of financial analysts' earnings forecasts after mergers. Specifically, I predict lower forecast errors for firms that experienced mergers after the enactment of SFAS 141, 142 than for firms that went through business combinations before those accounting changes. Study results present strong evidence that earnings forecast errors for companies involved in merging and acquisition activity decreased after the adoption of SFAS 141, 142. Test results also suggest that lower earnings forecast errors are attributable to factors specific to merging companies such as SFAS 141, 142 but not common to merging and non-merging companies. In addition, evidence implies that information in corporate annual reports of merging companies plays the critical role in this decrease of earnings forecast error. Summarily, I report that SFAS 141, 142 were effective in achieving greater transparency of financial reporting after mergers. In my complementary analysis, I also document the structure of corporate analysts' coverage in "leaders/followers" terms and conduct tests for differences in this structure: (1) across post-SFAS 141,142/pre-SFAS 141, 142 environments, and (2) between merging and non-merging firms. Although I do not identify …

This study was concerned with reducing children's anticipatory anxiety when entering mental health services for the first time. The purpose of this study was to determine whether combining two effective modalities, play therapy and animal-assisted therapy, would be effective in decreasing children's biobehavioral measurements of anxiety. Specifically, this study examined the effects of the presence of a trained therapy dog during one individual 30-minute play therapy session. The experimental group consisted of 26 children who received one individual 30-minute play therapy session with the presence of a trained therapy dog. The comparison group consisted of 25 children who received one individual 30-minute play therapy session without the presence of a trained therapy dog. The SenseWear® PRO 2 armband monitor measured children's biobehavioral measurements such as galvanic skin response, temperature, and activity level (BodyMedia, Inc., Pittsburgh , PA , www.bodymedia.com). The Tanita 6102 Cardio® digital heart rate monitor measured children's pre-treatment and post-treatment heart rates (Tanita Corporation of America, Inc., Arlington Heights , IL , www.tanita.com). Five hypotheses were tested using repeated measures ANOVA with mixed factors and eta squared. All five hypotheses in this study were retained based on statistical significance at the .05 level. The combination of child-centered play …

The incorporation of fluorine into SiO2 has been shown to reduce the dielectric constant of the existing materials by reducing the electrical polarizability. However, the incorporation of fluorine has also been shown to decrease film stability. Therefore, new efforts have been made to find different ways to further decrease the relative dielectric constant value of the existing low-k materials. One way to reduce the dielectric constant is by decreasing its density. This reduces the amount of polarizable materials. A good approach is increasing porosity of the film. Recently, fluorinated silica xerogel films have been identified as potential candidates for applications such as interlayer dielectric materials in CMOS technology. In addition to their low dielectric constants, these films present properties such as low refractive indices, low thermal conductivities, and high surface areas. Another approach to lower k is incorporating lighter atoms such as hydrogen or carbon. Silsesquioxane based materials are among them. However, additional integration issues such as damage to these materials caused by plasma etch, plasma ash, and wet etch processes are yet to be overcome. This dissertation reports the effects of triethoxyfluorosilane-based (TEFS) xerogel films when reacted with silylation agents. TEFS films were employed because they form robust silica …

This research examines the coping processes of African American women with breast cancer and how those processes relate to low usage of cancer support groups by these women. Prior coping research has utilized predominantly White samples. The limited research on African American coping responses is conflicting and characterized by small samples and non-probability sampling techniques. In this study, 26 respondents from Central and North Texas metropolitan areas were interviewed, including 9 key informants, 9 African American breast cancer survivors, and 8 White survivors. The data suggest that African American and White women cope with breast cancer in significantly different ways. Culture appears to account for the differences. All African American breast cancer survivors identified faith as their primary coping strategy. In contrast, only half of the White survivors claimed faith as their primary coping strategy, but like the other White survivors, tended to rely on multiple coping strategies. The African American survivors conceptualized God as an active member of their support network. Most prayed for healing, and several attributed examples of healing to God's intervention. The White survivors found God's presence in the actions of other people. They prayed for strength, peace, and courage to endure the illness. The use …

This study examined the relationship between success of small businesses and the educational backgrounds of their owners. A survey composed of questions concerning demographics, educational backgrounds, and business success was mailed to 1100 businesses in Dallas, Denton, and Tarrant counties in Texas. There were 228 usable responses which were analyzed by using the Statistical Package of Social Sciences (SPSS12). Data were sorted so that educational level, sales volume, number of employees, and longevity, were identified on a 5-point ordinal scale. Educational major was identified on a 5-point nominal scale. Pearson's correlation was used to determine whether relationships existed between founders' educational background and small business success. Spearman's correlation was used to determine the direction and strength of the relationships. Then educational level and major were combined with age, gender, ethnicity, and industry, to determine the relationships between founders' educational background, and business success. For this purpose a canonical correlation was used. Five opinion questions concerned influence of college education on business success among college graduates and non-college graduates were identified on a 5-point Likert scale and tested using one-way ANOVA, and independent sample t-test. When educational level and major were the only predictors of business success, a statistically significant relationship …

Groupware packages are increasingly being used to support content delivery, class discussion, student to student and student to faculty interactions and group work on projects. This research focused on groupware packages that are used to support students who are located in different places, but who are assigned group projects as part of their coursework requirements. In many cases, students are being asked to use unfamiliar technologies that are very different from those that support personal productivity. For example, computer-assisted cooperative work (CSCW) technology is different from other more traditional, stand-alone software applications because it requires the user to interact with the computer as well as other users. However, familiarity with the technology is not the only requirement for successful completion of a group assigned project. For a group to be successful, it must also have a desire to work together on the project. If this pre-requisite is not present within the group, then the technology will only create additional communication and coordination barriers. How much of an impact does each of these factors have on the acceptance of CSCW technology? The significance of this study is threefold. First, this research contributed to how a user's predisposition toward group work affects …

This study is a follow-up to a study completed by Dr. Thomas Barker in 1994 entitled The Status of the Implementation of International Education in Texas Four-year Colleges and Universities: A Comprehensive Study. A survey of 35 Texas universities and 6 out-of-state benchmark universities revealed information regarding the international programs at these universities in four areas. The four areas surveyed include: (a) administrative, (b) instructional, (c) international student support services, and (d) outreach. A summary of the survey results includes 34 tables detailing the university responses for the 2004 survey compared with the responses obtained from the original, Barker (1994). The results from the 2004 participating benchmark institutions were also reviewed. Texas universities continue to work toward the internationalization of the curriculum with increased numbers supporting an international focus in their mission statements and staffing patterns. Benchmark institutions continue to lead Texas institutions in a majority of areas surveyed. Funding for international education continues to be an issue for both the benchmark and Texas institutions. Changes in attitudes and immigration policies continue to affect the implementation of international programs on the university level. While universities continue to provide support to community and businesses in the area of international education, the …

Person-environment (PE) fit has been considered one of the most pervasive concepts in psychology. This study presents an integrative investigation of three levels of PE fit: person-vocation (PV) fit, person-organization (PO) fit, and person-job (PJ) fit, using multiple conceptualizations (e.g., value congruence, needs-supplies fit) of each fit level. While a trend in the PE fit literature has been the inclusion of only one fit level with a single conceptualization, researchers call for the addition of multiple conceptualizations of multiple fit levels in a single study. Traditionally, PO fit has been conceptualized as value congruence, whereas PV fit has remained untouched in the literature investigating the direct measurement of fit perceptions. Therefore, new fit perceptions scales assessing PO fit using a needs-supplies fit conceptualization and PV fit using a variety of conceptualizations were introduced. To address the limitation of employing direct measures, common method variance was modeled with a positive affect factor. The study accomplished two objectives. First, a previously supported three-factor model of fit perceptions consisting of PO value congruence (PO-VC), PJ needs-supplies (PJ-NS), and PJ demands-abilities (PJ-DA) fit was strongly replicated. Second, this model was expanded by examining additional conceptualizations (needs-supplies, demands-abilities fit, value, personality, and interest congruence) of …

Knowledge management is a major concern for organizations today, and in spite of investments in technology, knowledge transfer remains problematic. This study sought to determine whether a relationship exists among participant group demographics (experience), implementation of an integrated knowledge transfer system (best practices model), knowledge transfer barriers, and knowledge transfer project (Web-based training) outcome in a virtual organization. The participant organization was a network of individuals and groups who practice patient advocacy in the research and treatment of cancer. These advocates volunteer in various capacities and are not collocated nor do they report to any single organizational entity. Volunteer participants were randomly assigned to a treatment or control condition. The treatment participants received a training supplement based upon a best practices knowledge transfer model. All participants reviewed a Web-based communications training module scheduled for deployment by the participant organization. Upon completion of the training program, participants were instructed to practice specific techniques from the program. At the end of this period, participants completed an online survey that measured demographics, perceived barriers to the knowledge transfer, and project outcome. Knowledge transfer barriers were defined as knowledge, source, recipient, and organizational context characteristics that inhibit the expected transfer. Project outcome was a …

Presently there are four generational cohorts in the workplace. Born from 1977 to 1997, the youngest cohort group, referred to as Generation Y (or Gen Y) in this study, has 81 million members, of whom over 29 million are already in the workplace. The importance of leader-subordinate relationships in the workplace has been confirmed; in recognizing this, leaders must identify and adapt to the changing era-shaped needs of employees, who cannot fully participate in organizational life if their most urgent needs are not being met. Because Gen Y employees are only now entering the workforce, little is actually known about the workplace needs of this cohort group. This study attempted to determine leadership needs of a Gen Y cohort as a means to enhance workplace relationships in the 21st century organization. A sequential, mixed methods study was employed to explore leadership preferences of a Gen Y cohort. Initially, focus group interviews were used to generate leadership themes. Based on these themes, an instrument was designed, and Gen Y business students from three higher education institutions were surveyed. Confirmatory factor analysis using LISREL software was used to test the themes. The driving force behind this research design was to build a …

In March 1942, the 2nd Battalion, 131st Field Artillery Regiment, 36th Division, surrendered to the Japanese Imperial Army on Java in the Dutch East Indies. Shortly after the surrender, the men of the 2nd Battalion were joined as prisoners-of-war by the sailors and Marines who survived the sinking of the heavy cruiser USS Houston. From March 1942 until the end of World War II, these men lived in various Japanese prison camps throughout the Dutch East Indies, Southeast Asia, and in the Japanese home islands. Forced to labor for their captors for the duration of the conflict, they performed extremely difficult tasks, including working in industrial plants and mining coal in Japan, and most notably, constructing the infamous Burma-Thailand Death Railway. During their three-and-one-half years of captivity, these prisoners experienced brutality at the hands of the Japanese. Enduring prolonged malnutrition and extreme overwork, they suffered from numerous tropical and dietary diseases while receiving almost no medical care. Each day, these men lived in fear of being beaten and tortured, and for months at a time they witnessed the agonizing deaths of their friends and countrymen. In spite of the conditions they faced, most survived to return to the United States …
