The Use Of Effect Size Estimates To Evaluate Covariate Selection, Group Separation, And Sensitivity To Hidden Bias In Propensity Score Matching.

Description: Covariate quality has been primarily theory driven in propensity score matching with a general adversity to the interpretation of group prediction. However, effect sizes are well supported in the literature and may help to inform the method. Specifically, I index can be used as a measure of effect size in logistic regression to evaluate group prediction. As such, simulation was used to create 35 conditions of I, initial bias and sample size to examine statistical differences in (a) post-matching bias reduction and (b) treatment effect sensitivity. The results of this study suggest these conditions do not explain statistical differences in percent bias reduction of treatment likelihood after matching. However, I and sample size do explain statistical differences in treatment effect sensitivity. Treatment effect sensitivity was lower when sample sizes and I increased. However, this relationship was mitigated within smaller sample sizes as I increased above I = .50.

Genetic and Environmental Factors that Mediate Survival of Prolonged Oxygen Deprivation in the Nematode Caenorhabditis Elegans

Description: Ischemic events of even a very short duration are not tolerated Ill in humans. The human cost of ischemia, when looked at as combined cardiovascular disease, dwarfs all other causes of death in the United States. Annually, CVD kills as many people in the US as does cancer, chronic lower respiratory disease, accidents, and diabetes mellitus combined. In 2005 (the latest year for which final statistics are available), CVD was responsible for 864,480 deaths or 35.3 percent of total deaths for the year. In my study, I have used the nematode Caenorhabditis elegans to determine genetic and environmental modulators of oxygen deprivation a key component of ischemia. I have found that animals with mutations in insulin like signaling pathways, neuronal function, electron transport chain components, germline function, and animals that are preconditioned by being raised on a diet of E. coli HT115 bacteria at 25°C have an enhanced ability to survive long-term (>72 hours) anoxia (<.005 kPa O2) at 20°C. The enhanced anoxia survival phenotype partially correlates with increased levels of carbohydrate stores in the nematodes. Suppression of this enhanced anoxia survival phenotype is possible by altering expression of the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase, the FOXO transcription factor DAF-16, and 5’-AMP kinase.

La Tradición Erótica Y La Vanguardia En La Poesía De Ernestina De Champourcín

Description: The unfolding of eroticism always has been controlled socially; its expression forbidden for the women and accepted for the men. Ernestina de Champourcín’s poetry is an example of the presence of eroticism and the Avant-Garde in Spanish poetry. Champourcín becomes a member of the Generation of ‘27 after appearing in the prologue of Gerardo Diego’s anthology, Poesía Española Contemporßnea (1934). According to this thesis, the shortage of studies on her work is due to her exile, not to the Spanish Civil War. The exposition celebrates the life and work of Champourcín and studies the relationship between the Avant-Garde and sensuality in her poetry and in poems of Pedro Salinas and Vicente Aleixandre. It compares their individual handling of the Avant-Garde, the sexual act, and love, and concludes that Champourcín’s poetry is as Avant-Garde and erotic as the works of her companions of the Generation of ‘27.

Exploring Sustainability VALS: Sustainability Value, Lifestyle Practices and Stewardship

Description: Living sustainability is a set of behaviors for the long-term functioning of society. Sustainability VALS provides the clothing and textiles industry distinctive insight into comprehending the phenomenon through the application of the appropriate theoretical platform. The objectives are to identify the dimensionality of sustainability value, sustainability practices and sustainability stewardship in consumers’ perceptive, and to examine the impacts of sustainability value and stewardship on sustainability practices. Analyzing data (n = 239) from a southwestern university reveals the critical dimensions of sustainability lifestyle practices, sustainability value and sustainability stewardship. 62 out of 64 hypotheses were confirmed the significant impacts of sustainability values and stewardship on sustainability lifestyle practices. The findings revealed that the altruistic, openness to change, anthropocentrism, and ecocentrism values are influential sustainability values affecting on sustainability lifestyle practices. Given the theoretical perspective of sustainability VALS, sustainability stewardships can facilitate the holistic idea to incur consumer’s sustainability lifestyle practices.

Organizational Citizenship Behaviors Among Public Employees In Guadalajara Metropolitan Area, Mexico

Description: This study develops a theoretical framework to examine the major dimensions of transformational leadership style (TLS), public service motivation (PSM), organizational citizenship behavior (OCB), and public organization performance (POP). It is hypothesized that when employees perceived a public organization is practicing a transformational leadership style, they are likely to have a favorable view on the performance of their organization, but the effect is indirect and mediated by OCB. At the same time, if employees have a strong desire to serve and improve the welfare of others, they are likely to perform beyond their job requirements and thus, likely to express a positive view on the organizational performance. A structural equation modeling was used to examine 1,016 public employees (67.7% response rate) in the Guadalajara metropolitan area, Mexico i.e., concerning their perceptions about leadership style, motivation to serve in the public sector, citizenship behaviors, and public organizational performance. The results suggest that if Mexican public employees perceived their leaders to adopt a transformational leadership style, they were likely to have a favorable view on the performance of their organization (direct effect); and that, the effect is mediated by their tendency to engage in activities that would contribute to the functioning of the organization without expecting any kinds of reward (indirect effect). In addition, if employees have a strong motivation to serve in the public sector, they are also likely to have a favorable view on the performance of the organization; and that, the positive effect is mediated by their tendency to act for the goodness of other employees and organizations without expecting some form of reward (indirect effect). A multi-group analysis, based on the hypothesized model, revealed the associations varied across three groups: difference between male and female, places of employment within the public sector (i.e., local or state government), and ...

Electrochemical Quartz Crystal Microbalance Study Of Bismuth Underpotential Deposition On Ruthenium And On Electrochemically Formed Ruthenium Oxide

Description: Kinetics and thermodynamics of bismuth (Bi) underpotential deposition (UPD) on ruthenium (Ru) and on electrochemically formed Ru oxide are studied using electrochemical quartz crystal microbalance technique. The Bi UPD and Bi bulk deposition are observed both on Ru and on electrochemically formed Ru oxide electrodes. The anodic peak potential of Bi UPD shifts slightly to positive potential as the scan rate increases. The peak current ratio (IAnode/ICathode) of Bi UPD and Bi bulk increases as the scan rate increases. Bi monolayer coverage calculated from mass (MLMass) and from charge (MLCharge) with scan rates dependent are compared both in Bi UPD region and in Bi bulk region. Stability and oxidation time effects are also investigated. Bi UPD on Ru and on electrochemically formed Ru oxide are quasi-reversible, scan rate independent, oxidation time dependent, and have higher plating efficiency on Ru. However, Bi bulk deposition on Ru and on electrochemically formed Ru oxide are quasi-reversible, scan rate dependent, oxidation time independent, and have higher plating efficiency on electrochemically formed Ru oxide. Both Bi UPD adatoms and Bi bulk are unstable in 0.5M H2SO4.

Older Workers: Disability And Employment

Description: The purpose of this study was to explore the demographic variables, typical vocational services, and competitive employment rates of older workers, ages 40 - 69 years of age, with disabilities using the RSA-911 database. The results describe the types of services received and the competitive employment outcomes for state and federal vocational rehabilitation consumers receiving services in 2009. Furthermore the sample of older workers (N = 1,152) was equally stratified into three age groups. Older workers, aged 60 to 69, had higher levels of education, received more types of vocational services, and were competitively employed at a much higher rate than those in the other age groups. The methods, discussion, study limitations, and recommendations for future research are presented.

Predicting The Impact Of Abuse: Is Experiential Avoidance A Mediator?

Description: Intimate partner violence (IPV) occurs between two individuals who have formerly been or are currently in an intimate relationship. IPV includes physical violence, sexual violence, threats of physical or sexual violence, and emotional abuse (Kernic, Wolf, & Holt, 2000; Rennison & Welchans, 2000). Experiencing IPV is associated with a serious impact on psychological health (Afifi, MacMillan, Cox, Asmundson, Stein, & Sareen, 2008; Calvete, Corral , & EstΘvez, 2008). Research on other forms of trauma indicates that experiential avoidance (EA) plays an important role in psychological distress and psychopathology. Thus, it was hypothesized that EA would play a key role in the impact of IPV. Using the Baron and Kenny (1986) method, the current study examined whether EA was a mediator between IPV severity and psychological distress, and whether EA was a mediator between IPV severity and PTSD symptomology, more specifically. In addition, mediational analyses were run to determine if suppression changed the relationships between IPV severity and psychological distress, or IPV severity and PTSD symptomology. Using the same methods, EA and suppression were both also examined as mediators between psychological/verbal abuse severity and psychological distress, and between psychological/verbal abuse severity and PTSD symptomology. No significant results were found in a treatment sample. However, several mediations and partial mediations were found in an undergraduate sample. These findings are likely to impact treatment of individuals who have experienced IPV and demonstrate the utility of acceptance and mindfulness based interventions such as ACT with this population.

An Examination Of Three Texas High SchoolsÊ Restructuring Strategies That Resulted In An Academically Acceptable Rating

Description: This study examined three high schools in a large urban school district in Texas that achieved an academically acceptable rating after being sanctioned to reconstitute by state agencies. Texas state accountability standards are a result of the No Child Left Behind Act of 2011 (NCLB). Texas state law requires schools to design a reconstitution plan after the second year of receiving an academically unacceptable school rating for failing to meet the required standards on state assessments, dropout rates, and graduation rates. The plan must be implemented by the third year. A mixed methods approach was used to uncover the strategies that were successful during the restructuring initiative. Data was obtained from three sources: interviews, document analysis and surveys. Interviews were conducted with district administrators, campus based administrators and teachers of the three high schools. A sample of core content teachers were surveyed using questions from the MetLife Survey of the American Teacher: Collaborating for Student Success. Results revealed that each school chose to engage in a major form of restructuring that included the formation of a themed based magnet school. A team approach was used to devise, implement, and monitor the reconstitution plan. Common strategies unveiled in the study included the use of common assessments, collaborative planning among core teachers, professional development, continuous monitoring of student absences, extended learning times for students, and a focus on college readiness. Survey data revealed that the majority of teachers believed that collaboration positively impacted student achievement. It is recommended that schools undergoing restructuring choose a reconstitution option that allows for flexibility, use multiple resources to foster school improvement, and develop restructuring plans that serve as living documents. Further research is needed to study the principal's role in achieving an academically acceptable rating. This study could also be expanded to compare restructuring strategies of ...

Style And Performance Aspects In The Newly Published Piano Sonata By Witold Lutos?awski

Description: Polish composer Witold Lutos?awski (1913-1994) was one of the most representative composers of the twentieth-century. Lutos?awski’s style progressed from traditional to modern avant-garde. His Piano Sonata belongs to his first compositional period, and is the only extant work from his student years. His remarkable synthesis of classical structures and impressionistic harmonic sonorities distinguishes the Sonata. Lutos?awski’s Piano Sonata is divided into three movements, and each movement is written in traditional sonata allegro form, sonata form without development and modified sonata form respectively. The Sonata contains both considerable elements of Classicism and Impressionism, as well as traits of Post-romanticism and Neoclassicism. The evolution of Lutos?awski’s compositional language can be better understood through an in-depth study of his Piano Sonata. Although Lutos?awski did not allow the work to be published during his lifetime, this occurred posthumously, ten years after the composer´s death. The recent publication of the work, paired with its substantial technical demands, both account for the fact that the Sonata is not frequently performed. The complex textures of Sonata place extensive technical and musical demands on the performer. In this study, a detailed description of the composer´s early style and influences as relates to this work will be analyzed and technical and pianistic approaches necessary for a performance of the work will be addressed. Also, there are significant discrepancies between the manuscript and printed score, even though the edition is based on the manuscript. Only one manuscript survives and scholarly research involving the work is scarce. Discrepancies between the manuscript and the published edition will be detailed, with suggestions for performance. It is hoped that this study will provide interest and be conducive to better approach the performance of this Piano Sonata.

Indoor Localization Using Magnetic Fields

Description: Indoor localization consists of locating oneself inside new buildings. GPS does not work indoors due to multipath reflection and signal blockage. WiFi based systems assume ubiquitous availability and infrastructure based systems require expensive installations, hence making indoor localization an open problem. This dissertation consists of solving the problem of indoor localization by thoroughly exploiting the indoor ambient magnetic fields comprising mainly of disturbances termed as anomalies in the Earth’s magnetic field caused by pillars, doors and elevators in hallways which are ferromagnetic in nature. By observing uniqueness in magnetic signatures collected from different campus buildings, the work presents the identification of landmarks and guideposts from these signatures and further develops magnetic maps of buildings - all of which can be used to locate and navigate people indoors. To understand the reason behind these anomalies, first a comparison between the measured and model generated Earth’s magnetic field is made, verifying the presence of a constant field without any disturbances. Then by modeling the magnetic field behavior of different pillars such as steel reinforced concrete, solid steel, and other structures like doors and elevators, the interaction of the Earth’s field with the ferromagnetic fields is described thereby explaining the causes of the uniqueness in the signatures that comprise these disturbances. Next, by employing the dynamic time warping algorithm to account for time differences in signatures obtained from users walking at different speeds, an indoor localization application capable of classifying locations using the magnetic signatures is developed solely on the smart phone. The application required users to walk short distances of 3-6 m anywhere in hallway to be located with accuracies of 80-99%. The classification framework was further validated with over 90% accuracies using model generated magnetic signatures representing hallways with different kinds of pillars, doors and elevators. All in all, this dissertation ...

Life History And Secondary Production Of Cheumatopsyche Lasia Ross (Trichoptera: Hydropsychidae) With Respect To A Wastewater Treatment Facility In A North Texas Urban Stream

Description: This study represents the first shift in multivoltine life history of Cheumatopsyche species from a wastewater treatment plant (WWTP) in North America. Populations of C. lasia were examined upstream and downstream of the Denton’s Pecan Creek WWTP August 2009 through November 2010. C. lasia is multivoltine in Pecan Creek with three cohorts observed upstream of the WWTP and four possible cohorts downstream. A fourth generation was possible downstream as thermal inputs from WWTP effluent resulted in elevated water temperatures that allowed larval development to progress through the winter producing a cohort ready to emerge in spring. Production of C. lasia was 5 times greater downstream of the WWTP with secondary production estimates of 1.3 g m-2 yr-1 and 4.88- 6.51 g m-2 yr-1, respectively. Differences in abundance were due to increased habitat availability downstream of the WWTP in addition to continuous stream flow from inputs of wastewater effluent. Results also suggest that C. lasia is important for energy transfer in semiarid urban prairie streams and may serve as a potential conduit for the transfer of energy along with emergent contaminants to terrestrial ecosystems. These finding highlight the need for more quantitative accounts of population dynamics (voltinism, development rates, secondary production, and P/B) of aquatic insect species to fully understand the ecology and energy dynamics of urban systems.

Missed Opportunities: Examining The LiteracyExperiences Of African American Students Displaced By Hurricane Katrina.

Description: The purpose of this study was to examine how five African American middle school students, who were displaced by Hurricane Katrina represent their literacy experiences before, during, and after their displacement. Specifically, the two research questions were: (a) What are the stories that these middle school students tell about their lives, before, during, and after their displacement, and (b) What do their stories reveal about their literacy experience before, during, and after their displacement? Narrative Inquiry was the chosen methodology for the study, which allowed the participants to tell their experiences from a first-person perspective. It also encouraged the participants to reflect upon these experiences, in order to give meaning to their thoughts and emotions. Employing a critical lens and perspective, I constructed a narrative profile for each participant, which was then analyzed using these methods. Each narrative profile detailed the literacy experiences of the participants before Hurricane Katrina, during the transition period, and current literacy experiences now that the participants are resettled and attending school in the host city. These data were supplemented by archival data such as report cards, individual education plans (IEPs), and Texas Assessment of Knowledge and Skills (TAKS) scores. Data analysis of the five participants’ literacy experiences revealed common themes. These participants have pleasant memories of school literacy before the storm and mentioned “choice” as a component of those experiences. During the transition period, few or no literacy experiences took place. Hence, there were missed opportunities for the participants to use literacy experiences to make connections to their new world. Participants reported current classroom and school experiences were controlled environments that led to controlled literacy experiences. This compartmentalization of literacy experiences is not consistent with the critical literacy perspective adopted in this study. Their interviews suggested that they that they saw no connection between school ...

Molecular Structure Analyses of Asymmetric Hydrocarbon Liquid Compounds in the Gas Phase Using Chirped-pulse Fourier Transform Microwave Spectroscopy: Acyl Chlorides and Perfluorinated Acyl Chlorides

Description: Examinations of the effects of (a.) alkyl carbon chain length and (b.) perfluorination of acyl chlorides; propionyl chloride, butyryl chloride, valeroyl chloride, and perfluorinated acyl chlorides; perfluoropropionyl chloride and perfluorobutyryl chloride, are reported and compared using CP-FTMW spectroscopy. All of these molecules are already published in various journals except for valeroyl chloride. The chapters are organized by molecule alkyl chain length and include some background theory. Conformational stability, internal rotation, helicity, and ionic character of the C-Cl bond via the nuclear electric quadrupole coupling constant (χzz) are analyzed. Results show syn, syn-anti/syn-gauche, and syn-anti-anti/syn-gauche-anti stable conformations. Internal rotation was only seen in propionyl chloride. Helicity was not observed. (χzz) was observed to be inert to alkyl chain length, ~ 60 MHz and ~ 65 MHz for the nonfluorinated and fluorinated acyl chlorides. Partial fluorination and varying functional groups are recommended.

The Effect of Relationship Quality on Mental Representations of Social Support and Cardiovascular Reactivity

Description: The aim of the current study was to examine how thinking about qualitatively different social network members may differentially affect cardiovascular reactivity to a subsequent stressor. Eighty-two undergraduates were asked to think and write about different types of relationships preceding a social stressor. No differences between conditions in CVR were found during social support induction phase or the stressor task. Women in the supportive condition were found to have slower SV recovery than those in the ambivalent condition. The results of this study are inconsistent with previous evidence for a relationship between mental representations of social ties and CVR. Future research should seek to rule out confounding variables and clarify this effect.

Resilience Among High Achievers In An Instrumental Music Program

Description: Positive adaptations experienced in spite of challenges faced is known as resilience. Comparatively little research has focused on in-depth descriptions regarding how resilience is manifested in children. The purpose of this study was to add to previous research in the identification of characteristics of resilience in students, and to determine the extent to which band membership has aided their resilience in other domains. Data was collected from a random sample of band seniors from the class of 2011 (n = 3) who attended a large high school in the South. Specific research questions were: (1) What characteristics of resilience are present in the talk of participants in a high school instrumental music program? (2) To what extent has this population perceived that membership in band aided their resilience in other domains? A descriptive study design was chosen that used qualitative data. Following data analysis that included category matrices, prominent themes emerged from the participants’ responses. These included self-improvement, forward thinking, optimism, inner drive, increased achievement, determination, development of relationships to peers and adult mentors, and development of connectedness to the school. The findings of this study complemented previous research on characteristics of resilient students, and suggested that the participants derived positive benefits from group membership and from positively contributing to the school. Recommendations based on these findings for researchers included the need for resilience to be studied across other subject areas in school, and across different populations of students. Recommendations for teachers and administrators included varied opportunities for extra-curricular and co-curricular student engagement.

The Martial Arts of Medieval Europe

Description: During the late Middle Ages and into the Renaissance, fighting books—Fechtbücher—were produced in northern Italy, among the German states, in Burgundy, and on the Iberian peninsula. Long dismissed by fencing historians as “rough and untutored,” and largely unknown to military historians, these enigmatic treatises offer important insights into the cultural realities for all three orders in medieval society: those who fought, those who prayed, and those who labored. The intent of this dissertation is to demonstrate, contrary to the view of fencing historians, that the medieval works were systematic and logical approaches to personal defense rooted in optimizing available technology and regulating the appropriate use of the skills and technology through the lens of chivalric conduct. I argue further that these approaches were principle-based, that they built on Aristotelian conceptions of arte, and that by both contemporary and modern usage, they were martial arts. Finally, I argue that the existence of these martial arts lends important insights into the world-view across the spectrum of Medieval and early Renaissance society, but particularly with the tactical understanding held by professional combatants, the knights and men-at-arms. Three treatises are analyzed in detail. These include the anonymous RA I.33 Latin manuscript in the Royal Armouries at Leeds; the early German treatise attributed to Hanko Döbringer that glosses the great Johannes Liechtenauer; and the collection of surviving treatises by the Friulian master, Fiore dei Liberi. Each is compared in order to highlight common elements of usage that form the principles of the combat arts.

Stable Book-Tax Differences, Prior Earnings and Earnings Persistence

Description: This study resolves divergent prior findings relating book-tax differences to future earnings, determines whether prior literature has missed relationships between different types of book-tax differences and pre-tax and/or after-tax income, and investigates prior earnings as a factor contributing to the observed relationships. As past research has found that some firms have large book-tax differences over several years, this study separates these firms with large stable book-tax differences from others with large book-tax differences (non-stable) when investigating the link between large book-tax differences and future earnings. Finally, this study investigates whether the relationship between book-tax differences and future earnings reflects information about prior earnings and finds that prior earnings growth explains much of the lower persistence found for firms with large book-tax differences.

Jean-michel Defaye’s Á La Maniére De Debussy Pour Trombone Et Piano: A Compositional Comparison To Claude Debussy’s Harmonic, Melodic, And Rhythmic Practices

Description: Jean-Michel Defaye composed Á La Maniére de Debussy in 2001 as part of a series of trombone solos written to emulate the compositional styles of significant predecessors. This study compares Á La Maniére de Debussy to the harmonic, melodic, and rhythmic practices of Claude Debussy (1862–1918), an innovative French composer and recognized figure of musical Impressionism. At present, there is limited scholarship on Defaye’s Á La Maniére de Debussy and its compositionally imitative nature. The first section of this document presents a survey of historical information, current literature, and methods of examination. The second section provides biographical information on composers Jean-Michel Defaye and Claude Debussy. The third section exhibits a compositional comparison of Á La Maniére de Debussy to Debussy’s use of harmony, melody, and rhythm. The final section draws a conclusion to the piece’s importance to the trombone solo repertoire and includes an interview with French trombonist Jacques Mauger who collaborated with Defaye on Á La Maniére de Debussy. Although this document is not a performance guide, an informed performance of Á La Maniére de Debussy requires a trombonist to understand Debussy’s unique treatment of harmony, melody, and rhythm.

South Asian Women’s Experiences In Counseling: An Exploration Of Working Alliance, Multicultural Competence, Acculturation, And Cultural Value Conflicts

Description: The purpose of this study was to examine predictors of client-counselor working alliance by understanding the effects of acculturation, perceived multicultural competence in counselors, and cultural value conflicts among South Asian women. The study was based on a nonrandom sample of women ages 18 to 39 years living in the United States who had completed at least three counseling sessions with a mental health professional in the last 5 years. Forty participants completed the online survey. Participants were recruited through personal contacts, social networking Internet websites, businesses, agencies, and places of worship. The majority of participants were highly educated, second-generation women descending from India or Pakistan. The full survey included an eligibility screening questionnaire, demographic questionnaire, the Working Alliance Inventory-Short Revised with an average mean of 4.82, Cross-Cultural Counseling Inventory-Revised with an average mean of 4.17 and reliability of excellent internal consistency reliability at ? = .92, Asian Values Scale-Revised with an average mean score of 2.44, and Cultural Value Conflicts Scale for South Asian Women with a mean score of 3.33. Participants reported experiencing working alliance often within the therapeutic relationship and experienced middle levels of Asian value adherence, falling in the integration level. The results indicated that participants experienced neutral to agreeable cultural value conflicts. Bivariate correlations indicated a statistically significant, moderate relationship between participants’ perceptions of counselors’ multicultural competence and their reports of working alliance in the therapeutic relationship. All other correlations reflected small to moderate effect sizes; however, these correlations were not statistically significant. Similarly, bivariate regression indicated that perceptions of multicultural counselor competence predicted the client-counselor working alliance to a moderate degree. From the results of hierarchical linear regression, acculturation and cultural value conflicts did not predict client-counselor working alliance even after accounting for perceived multicultural competence in counselors. The strongest predictor of client-counselor working ...

A Characterization Of Jackson Blue Spring, Jackson County, Florida

Description: Jackson Blue is a first magnitude spring in the karst terrane of northeast Florida. Previous studies have identified inorganic fertilizer as the source of high nitrate levels in the spring. Agricultural land use and karst vulnerability make Jackson Blue a good model for conservation concerns. This work offers an aggregation of studies relating to the springshed, providing a valuable tool for planning and conservation efforts in the region. An analysis of nitrate levels and other water quality parameters within the springshed did not reveal significantly different values between agricultural and forested land use areas. Confounding factors include: high transmissivity in the aquifer, interspersed land use parcels, and fertilizer application in forested areas due to commercial pine stand activity.

Anti-bullying Policies And Practices In Texas Middle Schools

Description: For over a decade national attention to bullying in American schools has increased, fueled by publicity about suicides of severely bullied youth. Schools have the charge of maintaining the safety of all students in order to ensure a positive learning environment, but there is little information about what they are doing to prevent bullying. The purpose of this study was to provide information on principals’ perceptions of bullying and what anti-bullying policies, procedures, and programs exist in Texas middle schools. Ninety-nine principals completed an online questionnaire that addressed: 1) their knowledge of district and campus policies concerning bullying; 2) their direct experience with bullying; and, 3) bullying-prevention strategies and training in place in their schools. Principals reported direct experience with all types of bullying included on the questionnaire in their schools, but had a surprisingly small mean of 14.8 verified bullying incidents during the 2010-2011 year. Over 60% felt the level of physical safety in their school was good or very good, but only 35% rated their school’s emotional safety as good or very good. Students, parents, and teachers reported bullying to the majority of principals; however, few schools conducted annual student surveys that could provide accurate information about bullying in their schools. Procedures required by state law were more likely to be in place than those not required, though not all schools complied with all requirements. Fewer than 10% of schools had implemented a formal anti-bullying program. The most commonly cited obstacles to effectively addressing bullying were lack of time to conduct investigations and getting parents to file written reports (40%); however, despite having anti-bullying training, 27% felt limited by the lack of strategies. This study fills a void in the literature by providing a statewide overview of middle school principals’ knowledge of district and campus policies and procedures ...

An Experimental Examination Of The Effects Of Goal Framing And Time Pressure On Auditors’ Professional Skepticism

Description: Professional skepticism is a critical component of audit practice and current auditing standards direct auditors to remain skeptical throughout the duration of each audit engagement. Despite the importance and prevalence of an emphasis on professional skepticism throughout auditing standards, evidence indicates that auditors often fail to exercise an appropriate degree of professional skepticism. Prior accounting research suggests that auditors’ professionally skeptical behavior is affected by individual personality traits as well as situational (state) influences, whereby both factors contribute to auditor professional skepticism. Yet, prior research has primarily focused on trait skepticism; and little research to date has investigated the concept of state skepticism. The purpose if this research study is to experimentally investigate the impact of time pressure and trait skepticism on state skepticism, and to test a potential debiasing procedure on the impact of time pressure on state skepticism. In addition, this study examines the influence of both skepticism types on skeptical behavior.This research offers several contributions to accounting literature and practice. First, I contribute to the existing debate regarding the influences of professional skepticism by providing evidence that professional skepticism may be categorized as a temporary state, induced by situational aspects, in addition to being classified as an enduring trait. Second, I identify certain situational conditions which create differences in the level of state professional skepticism exhibited within an auditing context. Lastly, my findings may also be important to audit firms as they consider tools within their training arsenal equipped to promote an appropriate level of professional skepticism among employees. If auditor skepticism can be influenced by the frames they are provided, then audit firms may create an environment that promotes consistency in auditors’ application of professional skepticism, simply by engaging in goal framing.

Psychopathy and Antisocial Personality Disorder: Gender Differences in Empathy and Alexithymia

Description: Traditional conceptualizations of psychopathy highlight the importance of affective features of the syndrome in perpetuating social deviance. However, little research has directly investigated the callousness that psychopathic offenders display toward society and their victims. The current study investigated the roles of empathy and alexithymia in psychopathy among male and female incarcerated offenders, particularly in distinguishing psychopathy from antisocial personality disorder. Gender differences were also investigated. Regarding empathy, as predicted, group differences were largest between psychopathic and non-psychopathic offenders; no reliable differences emerged between psychopathic and APD-only offenders. In contrast, alexithymia robustly distinguished between offenders with prominent psychopathic traits, those with only APD, and those with neither condition. Psychopathic females unexpectedly exhibited slightly higher levels of alexithymia than their male counterparts, while empathic deficits were relatively consistent across genders. These findings are discussed in terms of improving assessment methods for the accurate identification and treatment of offenders with prominent psychopathic features.
