Predictive Relationships among Learner Characteristics, Academic Involvement, and Doctoral Education Outcomes

Description: The literature identifies multiple factors pertinent to learner characteristics and learning experiences that may promote doctoral education outcomes, and yet little quantitative research has examined relationships between those factors deemed important in the effectiveness of doctoral education. This study sought to examine predictive relationships among doctoral students’ learner characteristics, their involvement in mentorship and intellectual community, and doctoral education outcomes. Using Astin’s theory of involvement and the literature on signature pedagogies in doctoral education as conceptual guides, a survey instrument was constructed for the purpose of measuring variables identified as relevant to the effective formation of scholars. Central to the conceptualization of this study was academic involvement as represented by mentorship and intellectual community. The instrument was validated in a two-stage pilot testing process and administered to doctoral candidates at three public Texas higher education institutions. Of the 217 participants, the majority were female, White (Non-Hispanic), US citizens, and were pursuing education doctorates. Data were analyzed using multivariate statistical analyses. Reliability and validity estimates indicated psychometric integrity of the 20 observed variables measured to represent the constructs of mentorship and intellectual community. Results indicated that doctoral students’ learner characteristics were not notably predictive of doctoral students’ degree of involvement in mentorship and intellectual community (p < .05, R2 = .23). Doctoral students’ degree of academic involvement was strongly predictive of outcomes (p < .001, R2 = .58), particularly student satisfaction with the doctoral education experience and self-efficacy in conducting various forms of scholarly work. Of this effect, more tangible outcomes such as scholarly productivity and degree progress were not meaningfully related to academic involvement. Regardless of the frequency of academic involvement, students perceived faculty mentorship and intellectual community as very important. The predictive value and perceived importance of faculty mentorship and intellectual community highlight the critical role faculty and peer ...

Opera at the Threshold of a Revolution: Francis Poulenc’s Dialogues des Carmélites (1953-1956)

Description: Francis Poulenc’s three-act opera Dialogues des Carmélites (1953-1956) depicts the struggles of the novice nun Blanche de la Force during the Reign of Terror of the French Revolution. The use of Latin liturgical music at critical points in the opera conveys the ritualistic nature of Catholic worship. The spiritual message of mystical substitution, along with the closely related notion of vicarious suffering, imbue the opera with a spirituality that offers a sharp contrast to earlier operatic settings of Catholic texts, particularly during the age of grand opera. Marian devotion also plays an important role in the opera. The final tableau of the opera stages the execution of Blanche and her sisters, complete with the sound of a guillotine, with the nuns singing the Salve Regina as they proceed to the scaffold. The multivalence of the final tableau highlights the importance of voice and its absence. While the nuns, onstage spectators, and the guillotine are audibly present in the scene, the priest participates solely through gesture. The surfacing of the Lacanian Real in the silent moment of traumatic shock that follows the guillotine’s first fall allows for intertextual references to the opera in Poulenc’s Sonate pour Flûte et Piano (1957) to function as a work of remembrance.

The “Nigger Trinity”: Engaging the Discourse in Post Civil Rights/Post 1960s America

Description: The cultural and popular media landscape of the United States of America changed after the Civil-Rights movement of the 1960s. The word “Nigger” was changed during that same period of American history. There are several authors and a comic that helped change this word during the 1960s. The post Civil-Rights American has a different experience and understanding with this word than those born before 1970. This work triangulates the current cultural location of the word “Nigger,” “nigga,” and “the n-word” using linguistics, law, and two media case studies. The “Nigger” trinity is a model that adds value to the discourse that surrounds this one word in post civil-rights/post 1960s America.

Effect of Rancher’s Management Philosophy, Grazing Practices, and Personal Characteristics on Sustainability Indices for North Central Texas Rangeland

Description: To assess sustainability of privately owned rangeland, a questionnaire was used to gathered data from ranches in Cooke, Montague, Clay, Wise, Parker, and Jack counties in North Central Texas. Information evaluated included: management philosophy, economics, grazing practices, environmental condition, quality of life, and demographics. Sustainability indices were created based on economic and land health indicator variables meeting a minimum Cronbach‘s alpha coefficient (α = 0.7). Hierarchical regression analysis was used to create models explaining variance in respondents’ indices scores. Five predictors explained 36% of the variance in rangeland economic sustainability index when respondents: 1) recognized management inaction has opportunity costs affecting economic viability; 2) considered forbs a valuable source of forage for wildlife or livestock; 3) believed governmental assistance with brush control was beneficial; 4) were not absentee landowners and did not live in an urban area in Texas, and; 5) valued profit, productivity, tax issues, family issues, neighbor issues or weather issues above that of land health. Additionally, a model identified 5 predictors which explained 30% of the variance for respondents with index scores aligning with greater land health sustainability. Predictors indicated: 1) fencing cost was not an obstacle for increasing livestock distribution; 2) land rest was a component of grazing plans; 3) the Natural Resource Conservation Service was used for management information; 4) fewer acres were covered by dense brush or woodlands, and; 5) management decisions were not influenced by friends. Finally, attempts to create an index and regression analysis explaining social sustainability was abandoned, due to the likely-hood of type one errors. These findings provide a new line of evidence in assessing rangeland sustainability, supporting scientific literature concerning rangeland sustainability based on ranch level indicators. Compared to measuring parameters on small plots, the use of indices allows for studying replicated whole- ranch units using rancher insight. Use ...

Comparing Latent Dirichlet Allocation and Latent Semantic Analysis as Classifiers

Description: In the Information Age, a proliferation of unstructured text electronic documents exists. Processing these documents by humans is a daunting task as humans have limited cognitive abilities for processing large volumes of documents that can often be extremely lengthy. To address this problem, text data computer algorithms are being developed. Latent Semantic Analysis (LSA) and Latent Dirichlet Allocation (LDA) are two text data computer algorithms that have received much attention individually in the text data literature for topic extraction studies but not for document classification nor for comparison studies. Since classification is considered an important human function and has been studied in the areas of cognitive science and information science, in this dissertation a research study was performed to compare LDA, LSA and humans as document classifiers. The research questions posed in this study are: R1: How accurate is LDA and LSA in classifying documents in a corpus of textual data over a known set of topics? R2: How accurate are humans in performing the same classification task? R3: How does LDA classification performance compare to LSA classification performance? To address these questions, a classification study involving human subjects was designed where humans were asked to generate and classify documents (customer comments) at two levels of abstraction for a quality assurance setting. Then two computer algorithms, LSA and LDA, were used to perform classification on these documents. The results indicate that humans outperformed all computer algorithms and had an accuracy rate of 94% at the higher level of abstraction and 76% at the lower level of abstraction. At the high level of abstraction, the accuracy rates were 84% for both LSA and LDA and at the lower level, the accuracy rate were 67% for LSA and 64% for LDA. The findings of this research have many strong implications for the ...

Integrating Selective Herbicide and Native Plant Restoration to Control Alternanthera philoxeroides (Alligator Weed)

Description: Exotic invasive aquatic weeds such as alligator weed (Alternanthera philoxeroides) threaten native ecosystems by interfering with native plant communities, disrupting hydrology, and diminishing water quality. Development of new tools to combat invaders is important for the well being of these sensitive areas. Integrated pest management offers managers an approach that combines multiple control methods for better control than any one method used exclusively. In a greenhouse and field study, we tested the effects of selective herbicide application frequency, native competitor plant introduction, and their integration on alligator weed. In the greenhouse study, alligator weed shoot, root, and total biomass were reduced with one herbicide application, and further reduced with two. Alligator weed cumulative stem length and shoot/root ratio was only reduced after two applications. In the greenhouse, introduction of competitors did not affect alligator weed biomass, but did affect shoot/root ratio. The interaction of competitor introduction and herbicide did not significantly influence alligator weed growth in the greenhouse study. In the field, alligator weed cover was reduced after one herbicide application, but not significantly more after a second. Introduction of competitor species had no effect on alligator weed cover, nor did the interaction of competitor species and herbicide application. This study demonstrates that triclopyr amine herbicide can reduce alligator weed biomass and cover, and that two applications are more effective than one. To integrate selective herbicides and native plant introduction successfully for alligator weed control, more research is needed on the influence competition can potentially have on alligator weed growth, and the timing of herbicide application and subsequent introduction of plants.

Communication System over Gnu Radio and OSSIE

Description: GNU Radio and OSSIE (Open-Source SCA (Software communication architecture) Implementation-Embedded) are two open source software toolkits for SDR (Software Defined Radio) developments, both of them can be supported by USRP (Universal Software Radio Peripheral). In order to compare the performance of these two toolkits, an FM receiver over GNU Radio and OSSIE are tested in my thesis, test results are showed in Chapter 4 and Chapter 5. Results showed that the FM receiver over GNU Radio has better performance, due to the OSSIE is lack of synchronization between USRP interface and the modulation /demodulation components. Based on this, the SISO (Single Input Single Output) communication system over GNU Radio is designed to transmit and receive sound or image files between two USRP equipped with RFX2400 transceiver at 2.45G frequency. Now, GNU Radio and OSSIE are widely used for academic research, but the future work based on GNU Radio and OSSIE can be designed to support MIMO, sensor network, and real time users etc.

Student reflections as artifacts of self-regulatory behaviors for learning: A tale of two courses.

Description: The rapid growth of online and blended learning environments in both higher education and K-12, along with the development of innovative game based, narrative driven, problem-based learning (PBL) systems known as Alternate Reality Games (AltRG), has led to the need to understand student’s abilities to self-regulate their learning behaviors and practices in these novel environments. This study examines student reflections and e-mails related to self-regulatory practices for learning across two different course designs for an Internet-based course in computer applications. Both designs leverage PBL but apply different levels of abstraction related to content and the need to self-regulate. The study looked specifically at how students communicated about learning across these environments, what student communications indicated about student readiness for university online learning and how instructional design and methods of instruction shaped student expressions of learning and self-regulation. The research design follows an ethnographic and case study approach as two designs and four sections are examined. Data was collected from student blog posts, email messages and semi-structured interviews. Atlas.TI was used to code the data using constant comparative analysis. A sequential analysis was applied using an a priori structure for self-regulation and post hoc analysis for emergent codes that resulted in the following categories: distraction, group experience, motivation, emotion, prior experiences, and time. Results indicated qualitative differences between the two designs related to student communications for learning and self-regulation. Findings were reported for both the a priori and post hoc analysis. Additionally, two major findings are reported as emerging themes. These are presented and discussed as The Expectation Gap and Different Designs, Different Outcomes.

Investigating the Extractive Summarization of Literary Novels

Description: Abstract Due to the vast amount of information we are faced with, summarization has become a critical necessity of everyday human life. Given that a large fraction of the electronic documents available online and elsewhere consist of short texts such as Web pages, news articles, scientific reports, and others, the focus of natural language processing techniques to date has been on the automation of methods targeting short documents. We are witnessing however a change: an increasingly larger number of books become available in electronic format. This means that the need for language processing techniques able to handle very large documents such as books is becoming increasingly important. This thesis addresses the problem of summarization of novels, which are long and complex literary narratives. While there is a significant body of research that has been carried out on the task of automatic text summarization, most of this work has been concerned with the summarization of short documents, with a particular focus on news stories. However, novels are different in both length and genre, and consequently different summarization techniques are required. This thesis attempts to close this gap by analyzing a new domain for summarization, and by building unsupervised and supervised systems that effectively take into account the properties of long documents, and outperform the traditional extractive summarization systems typically addressing news genre.

Quantitative EEG Analysis of Patients with Chronic Pain: An Exploratory Study

Description: This study examined quantitative EEGs of six individuals with chronic pain and compared them to an age- and gender-matched normative database of healthy control subjects in an attempt to discern whether a particular pattern of resting state EEG activity is associated with chronic pain. In the chronic pain group, significantly reduced absolute power was seen in delta and theta bandwidths at frontal sites in the eyes-closed condition. In the eyes-open condition, significantly reduced absolute power was seen in delta, theta, and alpha bandwidths at frontal, central, and temporal sites, and increased relative high beta power was seen in the parietal region. Reduced theta/high beta and delta/high beta ratios were seen in the parietal region. Quantitative EEG neuromarkers of chronic pain are suggested.

Lone Star Booster: The Life of Amon G. Carter

Description: Abstract Though a very influential Texan during the first half of the twentieth century, Amon Carter has yet to receive a full scholarly treatment, a problem which this dissertation attempts to rectify by investigating the narrative of Carter’s life to see how and why he was able to rise from humble beginnings to become a powerful publisher who symbolized boosterish trends within Texas and the New South. Publisher of the Fort Worth Star-Telegram, philanthropist, oilman, and aviation supporter, Carter used his power and influence to become a leading booster of his city and region seamlessly making the transition from being a business progressive to New Deal supporter to an Eisenhower Democrat. His connections with corporations like American Airlines and General Motors helped bring aviation and industry to his region, and his ability to work with public and private entities helped inspire his failed attempt to make the Trinity River navigable up to Fort Worth. His own success at building the Star-Telegram into the largest circulating newspaper in Texas encouraged him to expand his media empire into radio and television, while the wealth he gained from his oil activities enabled him to form a philanthropic foundation that would provide support for Fort Worth’s medical, cultural, and educational needs for the future. Possessing a life marked by both success and failure, it is clear throughout this dissertation that Carter embodied the idea of the New South civic booster, a figure who at once promoted his goals for his city and region while understanding how this fit within the larger national context.

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.

Ecological Analysis of Physical Activity and Health-related Quality of Life in Female College Students.

Description: Health-related quality of life (HRQOL) is a comprehensive construct including physical and psychosocial health functioning. Despite significant health benefits of regular physical activity (PA), over 40% of female college students do not meet recommended PA guidelines to improve their health. This study investigated the influences of individual, social, and physical environmental factors on students’ PA and HRQOL. Participants were 235 female university students who completed validated surveys assessing their perceptions of PA, HRQOL, and social ecological factors. Three hierarchical regressions revealed individual and physical environmental factors as predictors of PA and HRQOL. These findings indicated health professionals need to consider students’ individual factors and physical environmental factors to promote female students’ PA and HRQOL.

Assessment of Transportation Emissions for Ferrous Scrap Exports from the United States: Activity-Based Maritime Emissions Model and Theoretical Inland Transportation Model.

Description: Industrial ecology is a field of study that encourages the use of closed-loop material cycles to achieve sustainability. Loop closing requires the movement of materials over space, and has long been practiced in the iron and steel industry. Iron and steel (ferrous) scrap generated in the U.S. is increasingly exported to countries in Asia, lengthening the transportation distance associated with closing the loop on the iron and steel life cycle. In order to understand the environmental cost of transporting this commodity, an activity-based maritime transportation model and a theoretical in-land transportation model are used to estimate emissions generated. Results indicate that 10.4 mmt of total emissions were generated, and emissions increased by 136 percent from 2004 to 2009. Increases in the amount of emissions generated are due to increases in the amount of scrap exported and distance it is transported.

ADHD Symptomology and Overweight Among College Men

Description: Attention deficit/hyperactivity disorder (ADHD) is a childhood disorder that often persists into adulthood. Among adults, ADHD is highly comorbid with addictive behaviors (e.g., substance abuse and dependence), and depressive disorders. Recently, an association between ADHD and obesity has been reported in the literature; emotional and binge eating may be “addictive behaviors” that contribute to weight gain in this population. The purpose of this study was to test competing models of the hypothesized link between ADHD symptomology and overweight. Specifically, in Model 1, symptoms of depression are expected to mediate the relationship between symptoms of impulsivity and inattention and emotional and binge eating which, in turn, leads to weight gain (i.e., increased BMI). In Model 2, however, the impulsive symptoms have direct relationships with emotional and binge eating in addition to being mediated by depressive symptoms. Structural equation modeling (SEM) was employed to test how the models fit the data of 790 college men. Both models fit the data well, with Model 2 being preferred because of its greater connection to theory. All paths were significant indicating that increased impulsive and inattentive symptoms predicted increased symptoms of depression that, in turn, predicted increased emotional/binge eating, which has a direct and positive relationship with increased BMI. Moreover, impulsive symptoms were also directly related to emotional/binge eating, suggesting different paths to overweight across ADHD subtypes. The findings of the current study elucidate the links between ADHD symptoms and overweight (i.e., increased BMI).

Effectiveness Of Group Activity Play Therapy On Internalizing And Externalizing Behavior Problems Of Preadolescent Orphans In Uganda

Description: This pilot study investigated the impact of group activity play therapy (GAPT) on displaced orphans aged 10 to 12 years living in a large children.s village in Uganda. Teachers and housemothers identified 60 preadolescents exhibiting clinical levels of internalizing and externalizing behavior problems. The participants ethnicity was African and included an equal number of females and males. Participants were randomly assigned to GAPT (n = 30) or reading mentoring (RM; n = 30), which served as an active control. Preadolescents in both treatment groups participated in an average of 16 sessions, twice weekly with each session lasting 50 minutes. Sessions were held in the school located within the village complex. A two (group) by two (repeated measures) split plot ANOVA was used to analyze the data. According to teacher reports using the Teacher Report Form (TRF) and housemother reports using the Child Behavior Checklist (CBCL), children receiving the GAPT intervention demonstrated statistically significant decreases (p < .025) in internalizing behaviors (TRF: p < .001; CBCL: p < .001 ) and externalizing behaviors (TRF: p = .006; CBCL: p < .001) from pretest to posttest compared to children who received RM. The GAPT intervention demonstrated a large treatment effect on reducing orphaned childrenÆs internalizing problems (TRF: ?p2= .213; CBCL: ?p2 = . 244) and a moderate to large treatment effect on reducing externalizing problems (TRF: ?p2= .121; CBCL: ?p2 = .217). The statistical, practical, and clinical significance of the findings provided strong, preliminary support for using GAPT as a developmentally and culturally responsive school-based intervention for troubled Ugandan orphans.

Risk Management And Market Efficiency On The Midwest Independent System Operator Electricity Exchange.

Description: Midwest Independent Transmission System Operator, Inc. (MISO) is a non-profit regional transmission organization (RTO) that oversees electricity production and transmission across thirteen states and one Canadian province. MISO also operates an electronic exchange for buying and selling electricity for each of its five regional hubs. MISO oversees two types of markets. The forward market, which is referred to as the day-ahead (DA) market, allows market participants to place demand bids and supply offers on electricity to be delivered at a specified hour the following day. The equilibrium price, known as the locational marginal price (LMP), is determined by MISO after receiving sale offers and purchase bids from market participants. MISO also coordinates a spot market, which is known as the real-time (RT) market. Traders in the real-time market must submit bids and offers by thirty minutes prior to the hour for which the trade will be executed. After receiving purchase and sale offers for a given hour in the real time market, MISO then determines the LMP for that particular hour. The existence of the DA and RT markets allows producers and retailers to hedge against the large fluctuations that are common in electricity prices. Hedge ratios on the MISO exchange are estimated using various techniques. No hedge ratio technique examined consistently outperforms the unhedged portfolio in terms of variance reduction. Consequently, none of the hedge ratio methods in this study meet the general interpretation of FASB guidelines for a highly effective hedge. One of the major goals of deregulation is to bring about competition and increased efficiency in electricity markets. Previous research suggests that electricity exchanges may not be weak-form market efficient. A simple moving average trading rule is found to produce statistically and economically significant profits on the MISO exchange. This could call the long-term survivability of the ...

An Examination Of Soft Skills Listed In Texas Electronic Job Postings And Undergraduate Business Information Systems Syllabi

Description: The purpose of this study was to explore the alignment of soft skills sought by current business IS entry-level employers in electronic job postings, with the integration of soft skills in undergraduate business information systems (IS) syllabi of public four-year universities in Texas. One hundred fifty job postings were extracted from two major electronic career databases. Ten undergraduate AACSB-accredited programs in the field of business information systems (IS) were investigated, and syllabi for the 70 major courses of the business IS programs were obtained for review. Content analysis was applied to all job postings and syllabi, exposing all soft skills related to the 9 categories used in this study adapted from the 21st Century Framework for Learning (Partnership for 21st Century Learning, 2009). Frequencies were tabulated to determine rank of soft skills in job postings and syllabi, and Jaccard’s coefficient statistic of occurrence was used for cluster analysis. Soft skills within all 9 categories were found in job postings (n = 1554) and course syllabi (n = 774). Three soft skill categories were aligned between job postings and syllabi: (1) initiative and self-direction, (2) social and cross-cultural skills, and (3) flexibility and adaptability. However, because differences in the higher ranked frequencies of soft skills in job postings and syllabi were noted, the null hypothesis of this study was rejected.

A Study Of The Perception Of Cataloging Quality Among Catalogers In Academic Libraries

Description: This study explores the concept of "quality" in library cataloging and examines the perception of quality cataloging among catalogers who work in academic libraries. An examination of the concept of "quality cataloging" in library science literature revealed that even though there is some general agreement on how this concept is defined, the level of detail and focus of these definitions often vary. These various perceptions were dissected in order to develop a framework for evaluating quality cataloging definitions; this framework was used to evaluate study participants' definitions of quality cataloging. Studying cataloger perceptions of quality cataloging is important because it is catalogers (particularly original catalogers) who are largely responsible for what is included in bibliographic records. Survey participants (n = 296) provided their personal definition of quality cataloging as well as their opinions on their department's cataloging, their influence upon their department's policies and procedures, and the specific data that should be included in a quality bibliographic record. Interview participants (n = 20) provided insight on how their opinions of quality cataloging were formed and the influences that shaped these opinions.

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.

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.

The Relationship Between Professional Sexual Boundary Violation And Sex Addiction: An Exploratory Study Of Post-treatment And Retrospective Pre-treatment Dispositions

Description: In this exploratory study, 35 male professionals who had successfully completed residential sex addiction treatment were surveyed. Respondents’ median age was 47.5, and reported ethnicities were White (89%), Asian, (9%) and Hispanic (2%). Prior to intake, 17 respondents had reportedly violated sexual boundaries with patients, clients, or staff (BV group) and 18 reportedly had not (NBV group). Respondents completed a demographic information form and two validated instruments: (a) Sexual Symptom Assessment Scale (S-SAS), measuring symptom severity of Compulsive Sexual Behavior (CSB); and (b) Boundary Violation Index (BVI), assessing frequency of risk factors for Sexual Boundary Violation (SBV). Respondents reported a very large decrease in CSB symptom severity over time (partial 2 = .856), change that was statistically equal for respondents in the BV and NBV groups. Furthermore, respondents reported a large decrease in SBV risk over time (partial 2 = .620); however, the BV group reported a greater decrease in SBV risk than the NBV group (partial 2 = .221). Reductions in both CSB symptoms and SBV risk were stable over time, up to five years post discharge. CSB symptoms and SBV risk were not correlated at retrospective pre-treatment, but for practical purposes, were moderately correlated at post treatment (r = 0.386, n = 25, p = 0.057). Although not significant, correlation at pre-treatment was more than twice as strong for the BV group than for the NBV group. Days of Treatment was a meaningful, although non-significant, contributor to decreases in CSB symptom severity (? = -.323). Similarly, Days of Treatment (? = -.785), Counseling (? = -.303), Recovery Support (? = -.292), and Continuing Education (? = -.259) were meaningful, although non-significant, contributors to decrease in SBV risk. At study participation, 77.1% of respondents had reportedly retained their professional licenses, although 15.4% reported having received a new licensing board ...

Ninth-grade Students’ Negotiation Of Aesthetic, Efferent, And Critical Stances In Response To A Novel Set In Afghanistan

Description: This qualitative, action research study was guided by two primary research questions. First, how do students negotiate aesthetic, efferent, and critical stances when reading a novel set in Afghanistan? Second, how do aesthetic and efferent stances contribute to or hinder the adoption of a critical stance? A large body of research exists that examines student responses to literature, and much of that research is based on the transactional theory of reading. However, it remains unclear how critical literacy fits into this theory. This study describes how one group of high school students’ aesthetic and efferent responses to a novel set in Afghanistan supported their development of critical stances. Six students enrolled in a ninth-grade English course participated in this study. Data were collected for 13 weeks. Data included two individual interviews with each student, student writing assignments in the form of 6 assigned journal entries and 7 assigned essays, transcriptions of 12 class discussions, field notes, lesson plans, a teacher researcher journal, and research memos. Data were analyzed using the constant comparative method. Three major findings emerged from this study. First, class discussions provided a context for students to adopt stances that were not evident in their individual written responses to the novel, which were completed prior to the discussions. Second, the discussions provided scaffolding that helped several of the students adopt world-efferent and critical stances. Third, both the aesthetic and the efferent stances contributed to students’ adoption of critical stances.
