Living in tune with nature means respecting the natural environment and realizing its power and the ways it manifests in daily life. This essay focuses on the ways in which respect for nature is expressed through animal imagery in Zora Neale Hurston's Their Eyes Were Watching God, Mark Twain's "The Stolen White Elephant," Roughing It, and Pudd'nhead Wilson, and Jack London's The Call of the Wild. Each author encouraged readers to seek the benefits of nature in order to become better human beings, forge stronger communities, and develop a more unified nation and world. By learning from the positive example of the animals, we learn how to share our world with them and with each other.

While student populations are growing, the gatekeeping devices of teacher certification examinations prevent many who want and are trained to teach from entering the profession. If failing these exams predicted failure to teach well, blocking students who do not pass certification exams from entering the profession might be a well-reasoned policy. However, many studies indicate that there is little correlation between certification test scores and quality of teaching. The present study investigated the effectiveness of a program to improve the scores of Texas elementary preservice teachers on a required certification exam. The program consisted of one-on-one coaching of preservice teachers upon the completion of coursework and prior to their taking the state's certification exam. Subjects' scores on a representative form of the certification test were used as pre-treatment measures. The content of the treatment program was individualized for each subject and determined by the specific items missed by each subject on the representative form. The post-treatment measure was the subject's score on the certification exam. Scores on the representative form and on the certification examination were compared to determine if there were significant differences between scores of preservice teachers who had been coached and those who were not coached. Since …

The increasing use of polymer-based materials (PBMs) across all types of industry has not been matched by sufficient improvements in understanding of polymer tribology: friction, wear, and lubrication. Further, viscoelasticity of PBMs complicates characterization of their behavior. Using data from micro-scratch testing, it was determined that viscoelastic recovery (healing) in sliding wear is independent of the indenter force within a defined range of load values. Strain hardening in sliding wear was observed for all materials-including polymers and composites with a wide variety of chemical structures-with the exception of polystyrene (PS). The healing in sliding wear was connected to free volume in polymers by using pressure-volume-temperature (P-V-T) results and the Hartmann equation of state. A linear relationship was found for all polymers studied with again the exception of PS. The exceptional behavior of PS has been attributed qualitatively to brittleness. In pursuit of a precise description of such, a quantitative definition of brittleness has been defined in terms of the elongation at break and storage modulus-a combination of parameters derived from both static and dynamic mechanical testing. Furthermore, a relationship between sliding wear recovery and brittleness for all PBMs including PS is demonstrated. The definition of brittleness may be used as …

Serious and violent juvenile offenders cause a disproportionate amount of harm to society, yet this population receives very little attention within the realm of empirical research. This research study examined the recidivism outcomes of 296 serious and violent offenders previously exposed to rehabilitative treatment in the Capital and Serious Violent Offender Program provided by the Texas Youth Commission. This group of juveniles was followed for three years following their release from institutionalization. This analysis revealed that 52% of those released were rearrested at least once during the follow-up period for any offense, while 48% of those released desisted from crime altogether. Of those 296 released, 34% were rearrested for at least one new felony offense. The analyses indicate that those involved in various forms of institutional misconduct during institutionalization were significantly more likely to recidivate. African-American race and institutional misconduct in the form of rule infractions emerged as the most consistent predictors of recidivism for this sample. This study concludes with a discussion of policy implications and risk assessment related to the decisions that are made to release this population of violent juvenile offenders.

Appointment no-shows are a problem in healthcare organizations. It is important that appointment intake and scheduling processes are effective in both meeting client needs and efficient in meeting organizational business requirements. This study examined baseline levels of appointment keeping in a not-for-profit medical/behavioral pediatric services clinic, analyzed existing administrative processes, introduced additional appointment keeping reminders, and presented systematic, performance management tutorials for clinic employees. Results indicate an increase in percentage of appointments kept and a decrease in appointment lag time.

Posttraumatic growth, defined as positive psychological changes in the aftermath of adversity and suffering, is a relatively recent focus in psychological research. The addition of this concept to the literature has provided a new, more resiliency-based framework through which to view survivors of various forms of trauma. Despite estimates that over half of all sexual assaults are not reported to the authorities, current crime statistics indicate that 1 in 4 women are sexually assaulted in their lifetime (Campbell & Wasco, 2005). Given the large percentage of the population that is impacted by sexual assault, it is essential that professionals better understand the factors that influence the successful healing and growth that can occur post-trauma. The purpose of this study was to further expand the literature on posttraumatic growth in sexual assault survivors by considering this phenomenon through the lens of attachment theory. Specifically, this study tested a proposed model of the inter-relationships among subjective and objective perceptions of threat during the sexual assault, adult romantic attachment, and posttraumatic growth. It was hypothesized that adult romantic attachment and parent-child attachment would mediate the relationship between subjective, or perceived threat, defined as the victim's perception of life threat, and objective threat, defined …

Relevance has been applied to various conditions in the marketing literature but no single definition has been developed. A single clear definition will be helpful to researchers investigating relevance in the marketing and consumer behavior fields. Confusion also exists in the literature regarding to what extent a symbolic visual in an advertisement is relevant. Many researchers are also calling for empirical evidence of a linkage between relevance and response through a theoretical measure of relevance. The central theory used in this dissertation is Sperber and Wilson's (1995) theory of relevance (TOR). TOR can help researchers and marketing managers by explaining how consumers may interpret visuals in advertising. TOR explains why some visuals thought to be unconnected with the product become relevant in advertising. This study makes the assertion that TOR has been underutilized and even ignored by some researchers in past marketing literature. Thus, TOR is used to provide greater explanatory power of consumers' interpretation and response to advertising visuals than what is currently realized by researchers and marketing managers. A reliable measure of relevance was developed using TOR as a foundation. Experiments were conducted to empirically test TOR and support was found for most aspects of the theory. This …

Educators and instructional designers are seeking ways to increase levels of learning. One of the ways this is being done is through cognitive load theory which attempts to reduce cognitive load through a better understanding of working memory and the factors that impact its function. Past studies have found that working memory processes visual and auditory information using separate and non-sharable resources (dual coding theory) and that by properly utilizing multimedia elements, information processing in working memory is more efficient (multimedia learning). What is not known is the effect that instructor-led video, which uses the visual channel but delivers no information, has on the cognitive load of the learner. Further, will the introduction of multimedia elements make the information processing of the learner more efficient? This study examined three ways in which instructional designers may create a more efficient learning environment through a better understanding of multimedia learning. First, by using the theories of multimedia learning, I examined a more efficient use of sensory memory. By minimizing extraneous load, which communication theory calls noise, on working memory through increased utilization of the visual and auditory channels, the effectiveness of instruction was increased. Secondly, the multimedia effect, defined as using visual …

This study explored how various intrapersonal, familial, and life-goal characteristics related to the academic and personal success of first semester early college entrants attending the Texas Academy of Mathematics and Science (TAMS) at the University of North Texas. The study sought to identify which intrapersonal factors and external factors affected grades, behavioral markers, and life satisfaction during the students' first semester at TAMS. Baseline data from TAMS entrance material such as standardized achievement test scores, previous grade point averages (GPA's), advanced courses taken, and other academic activities and awards were collected. Data were also collected from the students prior to their entry to the start of TAMS related to family cohesiveness, motivation, and career goals. Data from parents were gathered prior to the start of TAMS regarding parenting styles, demographics, parents' educational levels, careers, and income levels, as well as the child's homework, extracurricular activities, and other time demands. First semester grades, a measure of life satisfaction since the program began, and behavior reports from staff members were used as outcome/success indicators. These additional data were used to examine the relationship between success and familial/interpersonal/life goal factors.

Two hundred twenty individuals participated in the present study from a university population. The study examined the relationship among attachment styles to caregivers, relationship with God, depressive symptomology, and depressive experiences. Attachment theorists have suggested a connection between childhood attachment to caregivers and current attachment to God through the idea that individuals have "working models" that form how they interpret present relationships. For the most part, the results of the current study supported the idea of correspondence between attachment to caregiver and attachment to God. Individual attachment styles to caregivers matched their attachment style to God. However, when caregiver religiousness was included as a moderating variable, results supported the theory of combined compensation-correspondence for those with insecure attachments to caregivers. Individuals with insecure attachment to caregivers were more likely to compensate for their insecure attachment bonds through participation in religious activity, whereas their internal, private relationship with God corresponded with their previous insecure attachment bonds. Individuals with insecure attachment to caregivers were more likely to endorse symptoms of depression and report introjective, but not anaclitic, depressive experiences. With respect to attachment to God, introjective depressive experiences were positively related to both anxious and avoidant attachments, whereas, anaclitic depressive experiences were …

The issue of effortful patient performance has been an area of clinical interest in individuals with minor traumatic brain injury (mTBI). Clinical attention to this area has increased largely because of an increase in the number of worker's compensation claims, injury-related lawsuits and/or insanity defense pleas. As patients are presented with the opportunity for secondary gain, the issue of optimum performance on neuropsychological measures becomes salient. In addition to neurocognitive deficits, there are psychological characteristics associated with mTBI including depression, emotional disturbance, personality changes, and other psychopathology. This study utilized the MSVT, a set of standard neuropsychological instruments, and the Minnesota Multiphasic Inventory-2 (MMPI-2) to investigate the relationships between effort, psychological characteristics, and neuropsychological functioning in individuals with minor traumatic brain injuries. The first objective of this study was to determine which psychological factors were related to effort in mTBI. The second objective was to determine if there were differences between groups that performed poorly on effort testing and groups that performed adequately on effort testing, based on relevant psychological characteristics. The results of the analyses supported the first hypothesis. Hysteria was inversely related to effort, and Mania was positively related to effort on one of five measures of effort. …

This dissertation examined the effects of academic interventions on the development of reading academic competence in fourth grade students who performed at or below grade level as determined by TAKS reading scale scores. Fifty students in fifth grade were chosen to participate in the study from five elementary schools in the Fort Worth Independent School District in Fort Worth, Texas. Only 46 students completed the study. The study was conducted with a control (n = 23) and treatment group (n = 23). The fourth grade students were administered pretests and posttests using the ACES and the fourth grade TAKS reading test. This quantitative study used a quasi-experimental design to answer the research questions. The final data results did not indicate that the implementation of interventions significantly increased TAKS reading scores at the p > .05 level. In addition, there were no significant increases at the p > .05 level between the ACES pretests and posttests. Although there were no significant gains on the TAKS or ACES, there are implications the interventions had a positive effect on teacher perceptions of their students' academic competence and some growth was evident for the treatment groups on both TAKS and ACE.

This study analyzes the satisfaction of doctoral students in the joint doctoral program in Christian higher education between Dallas Theological Seminary (DTS) and the University of North Texas (UNT). The study focuses on the 18 students who have been identified as advanced participants in or graduates from the joint program from its inception in 1997 through its 10-year mark in 2007. Fourteen of the 18 eligible students agreed to participate in this study for a 77.8 % response rate. The doctoral students completed a survey that was created using a study of Garrett in 2006 of doctoral students at Historically Black Colleges and Universities and of McLaughlin in 2002 of graduate students in Christian education at DTS. The purpose of this study was to determine to what extent the joint doctoral program in higher education between both institutions meets the expectations of the students and prepares them for the range of careers that they then pursue. The study offers a number of findings surrounding the five research questions and offers several conclusions and recommendations for further research. The study concluded that the surveyed participants were immensely satisfied with their education experience thus assuming that the joint program does meet expectations …

Wireless sensor networks are ad hoc networks of tiny battery powered sensor nodes that can organize themselves to form self-organized networks and collect information regarding temperature, light, and pressure in an area. Though the applications of sensor networks are very promising, sensor nodes are limited in their capability due to many factors. The main limitation of these battery powered nodes is energy. Sensor networks are expected to work for long periods of time once deployed and it becomes important to conserve the battery life of the nodes to extend network lifetime. This work examines non-uniform grid-based routing protocol as an effort to minimize energy consumption in the network and extend network lifetime. The entire test area is divided into non-uniformly shaped grids. Fixed source and sink nodes with unlimited energy are placed in the network. Sensor nodes with full battery life are deployed uniformly and randomly in the field. The source node floods the network with only the coordinator node active in each grid and the other nodes sleeping. The sink node traces the same route back to the source node through the same coordinators. This process continues till a coordinator node runs out of energy, when new coordinator nodes …

Clinical research suggests that adolescent offenders often do not view their criminal behaviors as problematic and, therefore, are not motivated for treatment. Although customarily defined as a static characteristic, the transtheoretical model (TTM) proposes treatment amenability is dynamic and can be achieved through tailored interventions that motivate individuals for treatment. The current study examines the predictive validity of TTM measures for adolescent offenders at a maximum security correctional facility. In particular, the Stages of Change Scale (SOCS) and Decisional Balance for Adolescent Offenders (DBS-AO) were compared with a more traditional assessment tool utilized in evaluating treatment amenability of juvenile offenders (i.e., Risk-Sophistication-Treatment Inventory; RSTI). One hundred adolescent offenders from the Gainesville State School completed two waves of data collection with a 3-month time interval. Information was collected on offenders' treatment progress between waves. Consistent with TTM research, predictors of treatment progress included low scores on the Cons scale on the DBS-AO and on the Precontemplation scale on the SOCS. Participants in the most advanced levels of treatment also scored high on the Sophistication-Maturity scale on the RSTI and the Impression Management scale on the Paulhus Deception Scale.

This study evaluates archival data from a home intervention with an at-risk preschool child and her family. The intervention model studied was created by the Developmental Research Lab at Texas Christian University. Data was collected prior to and during the first 4 weeks of intervention to assess change in parent-child interaction, behavior and neurochemical profile. Measures used include coding of videotape recordings of the intervention, neurotransmitter levels taken via subject urine samples, Child Behavior Checklist, Parent Stress Index, and ACTeRS Parent Form. Results suggest positive change in parent-child interaction, behavior and neurochemical profile. However, consistent growth was not observed in several neurochemical results. Future studies should assess the entirety of the home intervention model and with a larger sample size.

Employee turnover has been one of the most serious issues facing the hotel industry for many years. Both researchers and practitioners have devoted considerable time and effort to better understand and indentify ways to decrease employee turnover. The purpose of this study was to examine the impact of individual differences focusing on career motivation and polychronicity on job satisfaction and its influence on employee turnover intention in the hotel industry. This study surveyed 609 non-supervisory employees working at two Dallas hotels. Respondents provided information regarding career motivations, polychronicity, job satisfaction, and turnover intention. Career motivations were significantly related to employee job satisfaction which impacted employee turnover intention. This finding can be useful to hotel companies and their managers when attempting to understand employee motivation.

The current study examined the relationships among attachment styles to parent, peer, and romantic partner, ability to regulate emotion, as well as engagement in sexual behaviors and substance use. Attachment theory and previous research suggests that an individual learns how to manage emotions through the modeling of appropriate techniques and a stable sense of self-worth. These two aspects develop through a secure attachment bond with an important figure. When an individual does not have a secure attachment bond in which to practice adaptive affect regulation strategies, he/she may attempt to manage emotions through external means, such as sexual behaviors or substance use. Overall, results supported these associations, with some notable exceptions. Across attachment sources a secure attachment style was related to lower levels of psychological distress and less engagement in substance use. In contrast to the findings from earlier studies, affect regulation did not mediate the relationship between attachment and substance use, and engagement in sexual behaviors was not significantly related to either attachment style or affect regulation.

Computer technology has been used in education for years, and the government budgets large amounts of money to foster technology. However, it is still a debated whether computer technology makes a difference in students' learning outcomes. The purpose of this study is to find if any relationship exists between computer use by teachers and students and the students' academic achievement in math and reading for both traditional populations and English language learner (ELL) tenth graders. Computer use in this study included the computer activities by students and teachers, in terms of the time, frequency, activities types, the places students use computers, teachers' computer activities, and the training teachers received. This study used data gathered from tenth grade students from the dataset Education Longitudinal Study of 2002 (ELS:2002) of the National Center for Education Statistics (NCES). Fifteen thousand, three hundred and sixty-two students were randomly selected to represent all U.S. tenth-graders attending schools in 2002. The findings showed diverse relationships consistent with the literature. Based on the findings, some suggestions were made to teachers and parents about the quality of school work and computer use by students and teachers.

This two-part study investigates the effectiveness of neurofeedback training for reducing behavioral problems commonly observed in abused/neglected children, and compares its efficacy to other treatment interventions with this population. Neuro-developmental sequelae of early relationship trauma are explored as an etiological framework for understanding disturbed affect-regulation, which appears central to the behavioral and emotional difficulties commonly experienced by this pediatric population. It is suggested that neurofeedback teaches children to self-regulate brain rhythmicity mechanisms, which in turn affects global improvements in behavior and mood. The pilot study utilizes records of 20 children removed from their biological homes by Child Protective Services. Children were assessed prior to treatment using the Child Behavior Checklist (CBCL) and the Test of Variables of Attention (TOVA), and again after 30 sessions of individualized, qEEG-guided neurofeedback training. A t-test analysis of pre- and post-scores was computed, and indicated significant improvements following treatment. A meta-analysis of existing literature on treatment interventions with abused/neglected children provides individual and aggregate effect sizes for 33 outcome studies with this clinical population, and contextualizes the results of the present pilot study within other empirically validated treatment modalities. Establishment of an overall effect size for treatment for this pediatric population provides a needed method …

Cardiac, metabolic and growth response of early-stage chicken embryos to perturbations in yolk environment was investigated. Also, effects of parental hypoxia exposure on hypoxia resistance, thermal tolerance and body length of zebrafish larvae were investigated. In the first study, thyroxine, triiodothyronine and testosterone produced differential effects on heart rate and development rate of chicken embryos during the first 4 days of development. Triiodothyronine caused a dose-dependent increase in heart rate when applied at 40 or 70 hours of age, while thyroxine caused a dose-dependent increase in heart rate when applied at 40 hours only. Testosterone and propyl-thiouracil (deiodinase antagonist) did not have an effect on heart rate. Development rate was not changed by thyroxine, triiodothyronine, testosterone or propyl-thiouracil, which suggested that heart rate changes did not result from changes in embryo maturity. In the second study, chicken embryos exposed to yolks of different bird species during early-stage embryonic development showed changes in heart rate, mass-specific oxygen consumption and body mass that scaled with the egg mass, incubation period length, and yolk triiodothyronine and testosterone levels of the species from which yolk was derived. In the third study, this phenomenon was investigated between layer and broiler chickens. Heart rate, oxygen consumption …

Repetitive self-mutilation (RSM) has become increasingly prevalent among adolescents. Empirical research has pinpointed several correlates of this behavior, but the initiation and maintenance of RSM among adolescents are not well understood. The experiential avoidance model (EAM) proposes that self-mutilation is a behavior that allows for the avoidance or alteration of unwanted internal experiences, and that it is negatively reinforced with repetition. The current study explored the usefulness of the EAM as an explanatory theory for adolescent RSM, with the additional incorporation of issues of social context. Adolescents (N = 211) from three school-based samples completed self-report questionnaires. One-third of students reported at least one incident of purposeful, non-suicidal self-mutilation and 16% had engaged in self-mutilation repeatedly within the past 6 months. Both regression and group analyses indicated that adolescents who engage in RSM report greater psychological distress, a greater incidence of functionally equivalent behaviors, and greater exposure to self-mutilation among peers and/or in the media, when compared to their counterparts who have not engaged in RSM. Suicidal ideation/behaviors were consistently the strongest predictors of current self-mutilation behaviors. Clinical implications, limitations, and suggestions for future research are discussed.

Though the remnants of a stereotype created over two millennia ago still thrive in American popular culture today, redheaded women are enjoying a more positive role in society than they have ever seen before. Women in Red explores the experience of the redheaded woman in America today by examining how the stereotypes have affected a small group of them, how these women relate to the stereotypes, and why, given the verisimilitude of the stereotype, a non-redheaded woman would embrace such an identity with the simple act of dying her hair red. This is the story behind the experience that is Women in Red.

This qualitative study described and examined the characteristics, components and theoretical design of the Student African-American Brother (SAAB). The SAAB is a national program that seeks to increase the academic and social integration of African-American males in higher education to increase their potential to graduate with an undergraduate degree. The SAAB's academic and social integration strategies were compared to Bean and Bennett's conceptual model of black student attrition to determine the congruency between the organization's strategies and the theoretical framework. The methodology was case study. Thirty semi-structured interviews were held with past and current members of the organization to gain a broader knowledge of the SAAB strategies and interventions used to promote their academic and social integration. The research revealed the SAAB applies a three dimensional approach which consists of providing a supportive environment, supporting academic goals, and encouraging campus and community involvement. This approach increases the students' understanding of the organization and structure of the higher education setting to yield successful matriculation through a four year college or university.
