Malingering is the deliberate production of feigned symptoms by a person seeking external gain such as: financial compensation, exemption from duty, or leniency from the criminal justice system. The Test Translation and Adaptation Guidelines developed by the International Test Commission (ITC) specify that only tests which have been formally translated into another language and validated should be available for use in clinical practice. Thus, the current study evaluated the psychometric properties of a Spanish translation of the Structured Interview of Reported Symptoms (SIRS). Using a simulation design with 80 Spanish-speaking Hispanic American outpatients, the Spanish SIRS was produced reliable results with small standard errors of measurement (SEM). Regarding discriminant validity, very large effect sizes (mean Cohen's d = 2.00) were observed between feigners and honest responders for the SIRS primary scales. Research limitations and directions for future research are also discussed.

Samuel Barber's Capricorn Concerto for flute, oboe and trumpet with strings is an important though seldom performed work. The concerto is teeming with performance choices that are indicative of both historical and contemporary influences. At present, there are limited resources available to performers regarding Capricorn. The first section of this study presents an historical and contextual examination of Capricorn both in terms of Barber's own compositional output and that of his influences and contemporaries. The second section includes a performance analysis of the work, while the third section includes an analysis of existing recordings. Implications for the performer are outlined in last section. The guide provides performers with pertinent background, analytical and performance information in order to facilitate informed, high-level performance.

Writing is an important life skill that all students need in order to succeed in today's society. However, proficient writing skills develop over time, requiring years of quality instruction combined with motivation, encouragement, and lots of practice. School-wide writing is an approach that provides specific writing instruction in a consistent manner across all grade levels, allowing students to develop increasingly complex writing skills and strategies over time. Implementation of programs, such as school-wide writing, requires teachers to transfer new understandings and skills from the training room to the classroom as well as efforts to sustain the program over time. This multiple case study examines the characteristics of an elementary school-wide writing program that was introduced in the field by local teachers and transferred five years later to another school in the same district. The study also examines factors affecting the transfer and sustainability of the program during the second year of implementation. Findings from the study indicate that the elements of school-wide writing transferred from School 1 to School 2 at a low road level of transfer. Factors affecting transfer included inquiry, ongoing training, support systems, authentic writing experiences, and time. Factors contributing to sustainability included ongoing support, accountability, communication, …

Children in low-income and ethnic minority families are more likely to be in poor health, which may impact physical and economic well-being in adulthood. This study explored how maternal depression and parenting efficacy were associated with child health outcomes in a sample of low-income African American and Latino families. Results demonstrated that children in optimal health were more likely to have mothers with high parenting efficacy and fewer depressive symptoms. Differences between African American and Latino families illustrated the importance of considering both socioeconomic and racial and ethnic disparities in child health simultaneously. Parent characteristics may be opportune targets for addressing child health disparities, and future research should focus on understanding these associations and identifying parent behaviors associated with child health.

The acquirement of a disability (e.g., spinal cord injury, traumatic brain injury, amputation, multi trauma) is a risk factor for psychological disturbance (e.g., depression). Research has established that social support and secure attachment are protective factors against psychological disturbance. Attachment patterns have also been associated with differences in perceived social support. Secure attachment and higher perceived social support have been implicated in greater levels of resilience but need to be validated with a population of individuals who have acquired a disability. The Experiences in Close Relationships, Social Provisions Scale, Connor-Davidson Resilience Scale, Personal Health Questionnaire - 9 Depression Scale, and a Demographic were administered to 102 adult inpatients at a rehabilitation hospital undergoing an individualized rehabilitation program. Two MANOVAs were conducted to examine the direct associations of attachment classifications with the major dependent variables, as well as the various social support subscales. Path analysis tested two mediational models suggested by literature. Model 1 assessed the mediating role of attachment anxiety and attachment avoidance on the effect of social support on depression and resilience. Model 2 assessed the mediating role of social support on the effect of attachment anxiety or attachment avoidance on depression and resilience. Partial support was obtained for …

Structural equation modeling was used to examine how childhood sexual abuse (and other associated variables, such as family functioning and experiencing multiple forms of abuse) relates to revictimization and psychological distress. Participants were women who participated in Project HOW: Health Outcomes of Women interviews, a longitudinal study that spanned six waves of interviews. Only women with a history of childhood sexual abuse were included in the present study (n=178). Experiencing nonsexual child maltreatment in addition to childhood sexual abuse appears directly related to adult sexual and physical revictimization and indirectly related to psychological distress. Childhood sexual abuse alone was not predictive of revictimization or psychological abuse. This suggests that other mediating factors may explain the relation between CSA and revictimization found in other research. Clinical implications based on the results of the present study emphasize the importance of identifying children who have experienced multiple forms of abuse as particularly at risk for future victimization. In addition, providing interventions with a focus on education and empowerment might decrease risk for future violence and subsequent emotional maladjustment. Potential future research could examine the treatment outcomes and efficacy of these interventions as well as identify those mediating factors that increase the risk for …

Two aluminum spherical mirrors with radii of 203.2 mm and radii of curvature also of 203.2 mm have been used to construct a tunable Fabry-Perót type resonator operational at frequencies as low as 500 MHz. The resonator has been incorporated into a pulsed nozzle, Fourier transform, Balle-Flygare spectrometer. The spectrometer is of use in recording low J transitions of large asymmetric molecules where the spectra are often greatly simplified compared to higher frequency regions. The resonators use is illustrated by recording the rotational spectra of bromobenzene and iodobenzene. In related experiments, using similar equipment, the pure rotational spectra of four isotopomers of SrS and all three naturally occurring isotopomers of the actinide-containing compound thorium monoxide have been recorded between 6 and 26 GHz. The data have been thoroughly analyzed to produce information pertaining to bond lengths and electronic structures.

The researcher examined the effectiveness of a near-death experience (NDE) learning module on reducing distressing aspects and enhancing a growth aspect of grief among bereaved adults. Participants were 22 females and 2 males; 2 identified as African American, 3 as Asian, 2 as Latina/o, and 17 as White; aged 20 to 71 years with mean age 35.3 years. In this experimental design, the researcher randomly assigned 12 participants to the experimental group and 12 participants to the waitlist no treatment control group. Participants in the experimental group received the NDE learning module intervention, which consisted of 3 sessions over consecutive weeks. Six research questions were explored. A two-factor repeated measures analysis of variance was performed on five dependent variables to determine if the two groups performed differently across time according to the pretest and posttest results of the Despair, Panic Behavior, Personal Growth, Detachment, and Disorganization subscales of the Hogan Grief Reaction Checklist (HGRC). A one-way analysis of covariance was performed on one dependent variable to determine if the groups were statistically different according to the posttest results of the Blame and Anger subscale of the HGRC. Additionally, univariate eta squared was hand calculated to determine practical significance. Findings indicated …

Most initial public offerings (IPOs) feature share lockup agreements, which prohibit insiders from selling their shares for a specified period of time following the IPO. However, some IPO firms agree to have a much longer lockup period than other IPO firms, and some are willing to lockup a much larger proportion of shares. Thus, the primary research question for this study is: "What are the reasons for the divergence of the lockup agreements?" The two main hypotheses that this dissertation investigates are the signaling hypothesis based on information asymmetry, and the commitment hypothesis based on agency theory. This study uses methods that have not been applied by previous studies in the literature relating to IPO lockups. First, I directly use IPO firms operating performance as a proxy for firm quality. The results show neither a negative nor a strong positive relationship between lockup length and firm operating performance. Thus, based on operating performance, the evidence does not support the agency hypothesis while showing weak support for the signaling hypothesis. I then examine the long-run returns for IPO firms with different lockup lengths. I find that firms with short lockup lengths have much better long-run returns than firms with long lockup …

This dissertation examines the ability of in vitro biotransformation assays to provide an indication of metabolic potential. The potential for xenobiotic compounds to bioconcentrate in aquatic organisms is expressed through the bioconcentration factor (BCF). The metabolic loss of ibuprofen, norethindrone and propranolol was measured using rainbow trout (Oncorhynchus mykiss) and channel catfish (Ictalurus punctatus) gill and liver S9 fractions, microsomes and cell suspensions. Metabolic transformation rates (kM) were extrapolated from in vitro intrinsic clearance of parent compound (CLm) and integrated into a refined BCF model. In general, CLm of test compounds was greater in liver S9 fractions and hepatocytes. However, the influence of hepatic metabolism on kM and BCF was limited by hepatic blood flow (20-25%) compared to gill blood flow (~100%). A significant difference was noted between BCF solely based on KOW and BCF including kM. These studies indicate that the inclusion of kM in BCF models can bring predicted bioconcentration estimates closer to in vivo values. Primary cell suspensions are preferred over subcellular fractions as cell suspensions possess both phase I and phase II enzyme activity. Further study was conducted on ibuprofen biotransformation pathways. As fish do not contain the same cytochrome P450 (CYP) 2C homologs known to …

This thesis is a comparative study on the late 16th century manuals of ornamentation by Girolamo Dalla Casa, Giovanni Bassano, Riccardo Rognoni, and Giovanni Battista Bovicelli. The study demonstrates that the latest Renaissance manual should be given more credit for the innovative ornamentation style that was to come in the Early Baroque era. Bovicelli's use of sequence, dissonances, and less moving notes for more rhythmic varieties are features most often associated in the style of the Baroque. Unfortunately, the topic of ornamentation in the late Renaissance is most commonly discussed as a group of different entities writing in the same style. The research for this paper is intended to separate the manuals of the late Renaissance, focusing on the separate styles that led to the work of Giovanni Battista Bovicelli.

Family communication has the potential to affect a variety of youth behavioral outcomes including adolescent sexual risk behavior. Within chapter 1, I present past literature on adolescent sexual risk behaviors, family communication patterns, and the gaps associated with those areas. In chapter 2, I review previous literature on adolescent sexual risk behavior, parent-child communication and family communication patterns. In chapter 3, I present the method which includes a description of the participants, procedures, measures, and data analysis used. In Chapter 4, I present the results of the study. According to the results of the study, father-child communication is not a better predictor of adolescent sexual risk behavior. A higher quantity of parent-child communication does not lead to less adolescent sexual risk behavior. Participants with a pluralistic family type do significantly differ from laissez-faire and protective family types in regards to levels of parent-child communication. Participants with a consensual family type do have significantly higher levels of parent-child communication in comparison to laissez-faire family types, but not protective family types. Finally, in chapter 5, I present the discussion with a review of previous research (consistent or inconsistent with the current findings), limitations and conclusions for the current study.

In this paper, I will show how applying a spatially explicit context to an existing environmental health surveillance framework is vital for more complete surveillance of disease, and for disease prevention and intervention strategies. As a case study to test the viability of a spatial approach to this existing framework, the risk of human exposure to Lyme disease will be estimated. This spatially explicit framework divides the surveillance process into three components: hazard surveillance, exposure surveillance, and outcome surveillance. The components will be used both collectively and individually, to assess exposure risk to infected ticks. By utilizing all surveillance components, I will identify different areas of risk which would not have been identified otherwise. Hazard surveillance uses maximum entropy modeling and geographically weighted regression analysis to create spatial models that predict the geographic distribution of ticks in Texas. Exposure surveillance uses GIS methods to estimate the risk of human exposures to infected ticks, resulting in a map that predicts the likelihood of human-tick interactions across Texas, using LandScan 2008TM population data. Lastly, outcome surveillance uses kernel density estimation-based methods to describe and analyze the spatial patterns of tick-borne diseases, which results in a continuous map that reflects disease rates based …

Transient electroluminescence (EL) was used to measure the onset of emission delay in OLEDs based on transition metal, phosphorescent bis[3,5-bis(2-pyridyl)-1,2,4-triazolato] platinum(ΙΙ) and rare earth, phosphorescent Eu(hfa)3 with 4'-(p-tolyl)-2,2":6',2" terpyridine (ttrpy) doped into 4,4'-bis(carbazol-9-yl) triphenylamine (CBP), from which the carrier mobility was determined. For the Pt(ptp)2 doped CBP films in OLEDs with the structure: ITO/NPB (40nm)/mcp (10nm)/65% Pt(ptp)2:CBP (25nm)/TPBI (30nm)/Mg:Ag (100nm), where NPB=N, N'-bis(1-naphthyl)-N-N'-biphenyl-1, 1'-biphenyl-4, MCP= N, N'-dicarbazolyl-3,5-benzene, TPBI=1,3,5-tris(phenyl-2-benzimidazolyl)-benzene, delayed recombination was observed and based on its dependence on frequency and duty cycle, ascribed to trapping and de-trapping processes at the interface of the emissive layer and electron blocker. The result suggests that the exciton recombination zone is at, or close to the interface between the emissive layer and electron blocker. The lifetime of the thin films of phosphorescent emitter Pt(ptp)2 were studied for comparison with rare earth emitter Eu(hfa)3. The lifetime of 65% Pt(ptp)2:CBP co-film was around 638 nanoseconds at the emission peak of 572nm, and the lifetime of neat Eu(hfa)3 film was obtained around 1 millisecond at 616 nm, which supports the enhanced efficiency obtained from the Pt(ptp)2 devices. The long lifetime and narrow emission of the rare earth dopant Eu(hfa)3 is a fundamental factor limiting device performance. Red …

The purpose of the current study was to examine the effects of using fixed time schedules with different magnitudes of stimulus delivery as treatment for pica. A functional assessment was conducted, which indicated that pica occurred across experimental conditions and was most frequent in the absence of social stimulation or contingencies. A competing stimulus assessment was then conducted to identify stimuli that could potentially compete with pica during NCR. Subsequently, an evaluation of the effects of reinforcer magnitude on NCR as a treatment of pica was conducted. Treatment results indicated that quantity of reinforcer increased the effectiveness of leaner schedules of reinforcer delivery; however, it was not possible to fade the temporal schedule to one that would have been useful in practice. In addition, limitations and future research are outlined.

This two-part thesis includes a critical preface and a collection of my poems. Using three poems-Louise Glück's "Lullaby," Bob Hicok's "Poem for My Mother's Hysterectomy," and Nick Flynn's "Memento Mori"-the critical preface examines how, in poetry, the transformation of a body negotiates trauma and triggers a conceptual shift, the creation and revision of identity, and the release of the duende's inspirational force. The collection of poetry that follows seeks to transfigure the body as a way to explore the nuanced traumas of human experience.

This qualitative inquiry explores a community-based art partnership called the semester programs that took place between Artpace San Antonio and Louis W. Fox Academic and Technical High School from 2004 until 2006. This narrative inquiry used interviews with artists and former Fox Tech art students involved in our program, along with my teacher/ researcher reflections, to make meaning from the data. The artists involved in the semester programs were Gary Sweeney, Daniel Guerrero, David Jurist, and Ethel Shipton. Former students interviewed include Eloy McGarity, Rosa Leija, John Contreras, and Jennelle Gomez, while I, Maria Leake represent the voice of the art teacher. Our stories of experience were analyzed and connections between situated learning theory, creativity theories, community-based art education, and memory research were all recognized as being exhibited during our community partnership programs. There were seven patterns and themes that were noted as occurring within each semester program, as well as notable distinctions. The patterns and themes from the data analysis suggest that our community partnership reflected the following: learning and creative expression went beyond the individual; networks of support and communication were available to all participants; challenges were acknowledged; empathy between participants was an unintentional outcome; working together as …

This study examined the correlates between the dependent variables African-American and Hispanic student enrollment in Texas public higher education to the independent variables institution type, education region, faculty demographics, curricular offerings and student organizations. Data for African-American (n = 124,000) and Hispanic enrollment (n = 314,000) in all Texas public higher education institutions (n = 109) for the 2008 academic year were examined. Significant results, using a statistical significance of p = .005, were reported for two of the variables. A correlation of Pearson's r = .946 and statistical significance of p = .000 was observed between African-American student enrollment and the percentage representation of African-American faculty in the same institution. A correlation of Pearson's r = .982 and statistical significance of p = .000 was observed between Hispanic student enrollment and the percentage representation of Hispanic faculty in the same institution. The results of this study found significant relationships between the presence of African-American and Hispanic faculty and enrollment of African-American and Hispanic students. Recommendations are made for exploring these findings in further detail.

Wireless sensor networks are composed of sensor nodes, which can monitor an environment and observe events of interest. These networks are applied in various fields including but not limited to environmental, industrial and habitat monitoring. In many applications, the exact location of the sensor nodes is unknown after deployment. Localization is a process used to find sensor node's positional coordinates, which is vital information. The localization is generally assisted by anchor nodes that are also sensor nodes but with known locations. Anchor nodes generally are expensive and need to be optimally placed for effective localization. Passive localization is one of the localization techniques where the sensor nodes silently listen to the global events like thunder sounds, seismic waves, lighting, etc. According to previous studies, the ideal location to place anchor nodes was on the perimeter of the sensor network. This may not be the case in passive localization, since the function of anchor nodes here is different than the anchor nodes used in other localization systems. I do extensive studies on positioning anchor nodes for effective localization. Several simulations are run in dense and sparse networks for proper positioning of anchor nodes. I show that, for effective passive localization, the …
