Magister Artium - MA / Praktiese ondervinding van die onderrig van Musiek op skoolvlak het getoon dat Musiekteoretiese vakke en Gehoorontwikkeling nie voldoende gestrukrureerd en gebaseer op wetenskaplik gefundeerde onderrigmetodes aangebied word nie. 'n Gebrek aan integrasie tussen Gehoorontwikkeling en die Musiekteoretiese vakke word vermoed. Innerlike gehoor is noodsaaklik is vir die musikus, maar bly grootliks onderontwikkel Hierdie studie konsentreer op die integrasie wat nodig is tussen die Musiekteoretiese vakke en Gehoorontwikkeling, en toets empiries die mening van musiekstudente by wyse van 'n vraelys en dié van musiekdosente by wyse onderhoude. Die ondersoek spreek die algemene metodes aan waardeur die betrokke vakke onderrig word, asook die probleme wat daarmee gepaard gaan. Die musiekstudent se mening omtrent sy tersiêre musiekopleiding word gevra. Daar is bevind dat die twee dissiplines nie doelmatig geïntegreerd aangebied word nie en voorstelle om die situasie te verbeter, word gemaak ..

It is my overall aim in this work to defend the view that knowledge is no more valuable than true belief or empirically adequate belief, and thus is not the primary epistemic good. I engage predominately with Jonathan Kvanvig‟s work for an assessment of the value of knowledge. In turn, I assess the arguments for the value of knowledge for their ability to support the view that knowledge is uniquely valuable. First I will consider an argument which relies on a purported connection between knowledge and proper action. It will then be suggested that arguments tying knowledge to our proper action are not adequate to justify this standard view of the value of knowledge. Furthermore, I will assess an argument that appeals to the value of truth to explain the superior value of knowledge. From this it will be concluded that truth is also less valuable than typically thought, consequently resulting in an overvaluation of knowledge. Lastly, I will investigate the possibility that knowledge has its value because of its stability and resistance to irrationality. Again, I will argue that this is insufficient justification of the standard view about the value of knowledge by offering counterexamples to both the stability of knowledge and knowledge‟s resistance to irrationality. After this I will discuss the implications of my analysis on the value of knowledge.

SLPs’clinical decisions are ideally grounded in evidence. However, it typically takes more than a decade for evidence-based recommendations to be implemented. This seminar will examine how three concepts: knowledge translation (KT), evidence-based practice (EBP), and practice-based evidence (PBE) can be understood and used to narrow the knowledge-to-action gap.

Visceral leishmaniasis (VL) is a serious neglected tropical disease that is endemic in 98 countries and presents a significant public health risk. The epidemiology of VL is complex. In the Americas, it is a zoonotic disease that is caused by a parasite and transmitted among humans and dogs through the bite of an infected sand fly vector. The infection also can be transmitted vertically from mother to child during pregnancy. Infected individuals can be classified as asymptomatic or symptomatic; both classes can transmit infection. In part due to its complexity, VL transmission dynamics are not fully understood. Stochastic compartmental epidemic models are a powerful set of tools that can be used to study these transmission dynamics. Past compartmental models for VL have been developed in a deterministic framework to accommodate complexity while remaining computationally tractable. In this work, we propose stochastic compartmental models for VL, which are simpler than their deterministic counterparts, but also have several advantages. Notably, this framework allows us to: (1) define a probability of infection transmission between two individuals, (2) obtain both parameter estimates and corresponding uncertainty measures, and (3) employ formal model comparisons. In this dissertation, we develop both population level and individual level Bayesian compartmental models to study both vector and vertical VL transmission dynamics. As part of this model development, we introduce a compartmental model that allows for two infectious classes. We also derive source specific reproductive numbers to quantify the contributions of different species and infectious classes to maintaining infection in a population. Finally, we propose a formal model comparison method for Bayesian models with high-dimensional discrete parameter spaces. These models, reproductive numbers, and model comparison method are explored in the context of simulations and real VL data from Brazil and the United States.

In this thesis, I aim to build upon recent attempts to situate a theory of virtue within work on character traits by social-cognitive scientists like Walter Mischel and Yuichi Shoda. I begin by examining the empirical adequacy of global cognitive-affective processing systems (CAPS) based character traits and virtues. I contend that empirical research does seem to support the existence of the former and is compatible with the existence of the latter. Next, I argue that one model of moral development that is compatible with my findings in the previous chapter is the communal and tradition based model of moral development. I go on to defend the claim that this model is also well-suited to play a significant role in an account of human moral development that is in keeping with my findings in the previous chapter. Here I specifically focus on pre-adult human moral development. I then turn my attention to consider human moral development in adults. I argue that character-friendships between adult human beings are compatible with and well-suited for CAPS based accounts of virtue that tie virtue to human flourishing. Recent empirical research on the impact of groups on helping behavior does not subvert the moral significance of character-friendships for adult moral development. I conclude my thesis by considering future issues that CAPS based virtue theorists need to address. This discussion is undergirded by my attempt to extend CAPS based accounts of virtue by defending three primary theses. First, some CAPS based theories of virtue are empirically adequate. Second, the communal and tradition based model of moral development is compatible and well-suited for such theories, particularly their accounts of pre-adult moral development. Third, character-friendships are compatible with and well-suited for adult moral development in said accounts of virtue. Instead of arguing for a single CAPS based account of virtue, I defend components and models of virtuous development that are consonant with a variety of accounts. Thus, while it excludes some accounts of virtue, my project is broad enough to serve as a framework for a number of different understandings of virtue.

abstract: Free/Libre Open Source Software (FLOSS) is the product of volunteers collaborating to build software in an open, public manner. The large number of FLOSS projects, combined with the data that is inherently archived with this online process, make studying this phenomenon attractive. Some FLOSS projects are very functional, well-known, and successful, such as Linux, the Apache Web Server, and Firefox. However, for every successful FLOSS project there are 100's of projects that are unsuccessful. These projects fail to attract sufficient interest from developers and users and become inactive or abandoned before useful functionality is achieved. The goal of this research is to better understand the open source development process and gain insight into why some FLOSS projects succeed while others fail. This dissertation presents an agent-based model of the FLOSS development process. The model is built around the concept that projects must manage to attract contributions from a limited pool of participants in order to progress. In the model developer and user agents select from a landscape of competing FLOSS projects based on perceived utility. Via the selections that are made and subsequent contributions, some projects are propelled to success while others remain stagnant and inactive. Findings from a diverse set of empirical studies of FLOSS projects are used to formulate the model, which is then calibrated on empirical data from multiple sources of public FLOSS data. The model is able to reproduce key characteristics observed in the FLOSS domain and is capable of making accurate predictions. The model is used to gain a better understanding of the FLOSS development process, including what it means for FLOSS projects to be successful and what conditions increase the probability of project success. It is shown that FLOSS is a producer-driven process, and project factors that are important for developers selecting projects are identified. In addition, it is shown that projects are sensitive to when core developers make contributions, and the exhibited bandwagon effects mean that some projects will be successful regardless of competing projects. Recommendations for improving software engineering in general based on the positive characteristics of FLOSS are also presented. / Dissertation/Thesis / Ph.D. Computer Science 2011

The purpose of this study was to confirm the four-factor model of the Child Interpersonal Relationship and Attitudes Assessment (CIRAA) in order to establish the instrument’s factor/structure validity using a sample different than that used in instrument development. The CIRAA was the first parent-report instrument based on child-centered theory and designed to measure play therapy outcomes. Its four factors are Self-Regulation (formerly Self-Control), Interpersonal Relationships, Coping Skills, and Internal Locus of Evaluation. For this study, the CIRAA was administered to 206 parents; their children were 75 females and 131 males aged 3 to 10 years old. The distributions of children’s genders and ages in this study were similar to the distributions of the sample used to develop the CIRAA. Based on confirmatory factor analysis results of overall goodness-of-fit indices; localized areas of strain; and interpretability, size, and statistical significance (p < .001) of the model's parameter estimate, the four-factor model of the CIRAA was confirmed with both theoretical and empirical support. Internal consistency reliability for the subscales and total score were acceptable, with an overall reliability coefficient of .928. A medium negative correlation (r = -.417, n = 47, p < .01) was found between the CIRAA total scores and Child Behavior Checklist Total Problems scores, a result in the expected direction. All subscales and total scores, except the Internal Locus of Evaluation score, distinguished differences between non-clinical and clinical samples. Altogether, results indicated that the CIRAA is appropriate for making clinical decisions about individuals. Limitations, additional implications, and future research are discussed.

Despite 30 years of research advancements, PTSD treatment remains a trial-and-error process as 22 veterans per day commit suicide to relieve their symptoms. Foa and Kozak's emotional processing theory informed this correlational study which included secondary data consisting of participants' self-rated scale scores to examine whether the independent variables number of deployments, guilt, depression, and anxiety predicted the dependent variable PTSD symptom reduction in a veteran sample with combat deployments and associated PTSD symptoms who completed accelerated resolution therapy (ART). An analysis of whether mean PTSD symptom reduction amounts differed by symptom severity levels was also completed. The study aimed to identify the first predictive treatment-matching model for PTSD symptom reduction by use of ART. A multiple regression analysis to determine whether the predictor variables predicted PTSD symptom reduction by use of ART resulted in nonsignificant findings (p = .517). A Welch ANOVA test to determine if mean PTSD symptom reduction differed among the low, moderate, and high PTSD symptom severity groups showed significant results (p = .002). Games-Howell post hoc analysis showed that mean differences in PTSD symptom reduction from the low to high PTSD symptom severity group was significant (p = .001) with a 26.1 point mean reduction for the high symptom severity group and a greater than 10-point mean PTSD symptom reduction for the low and moderate symptom severity groups. The findings confirmed a need for treatment-matching algorithm studies to predict which PTSD interventions most benefit veterans suffering with PTSD to reduce trial-and-error treatment approaches, associated comorbidities, and high rates of suicides.

Doctor of Philosophy (Phd) / Despite general agreement that severely emotionally disturbed children and adolescents are an "at risk" group, and that ongoing evaluation and research into the effectiveness of services provided for them is important, very little outcome evaluation actually takes place. The absence of well-conducted and appropriately interpreted studies is particularly notable for day or residential treatment programs, which cater for the most severely emotionally disturbed youths. This thesis outlines the main areas of conceptual, pragmatic and methodological confusion and neglect which impede progress in research in this area. It argues for plurality of data analytic strategies and research designs. It then critically reviews the reported findings about the effectiveness of day and residential treatment in specialist facilities, and the predictors of good outcomes for this treatment type. This review confirms that there is very little to guide practice. Having argued for the legitimacy of its methods and the necessity to address basic questions, the thesis reports the results of a naturalistic study based on data accumulated during a decade-long evaluative research program taking place at Arndell Child and Adolescent Unit, Sydney. The study addresses the question of what child, family and treatment variables predict outcome for 159 children and adolescents treated at this facility from 1990 to 1999. Statistically significant results with large effect size were obtained. Among the most disturbed subgroup of forty three children, (a) psychodynamic milieu-based treatment was shown to be more effective than the “empirically-validated” cognitive-behavioural treatment which superseded it in 1996, and (b) children from step-families showed better outcome than those from other family structures. Furthermore, it was found for the study sample as a whole that severe school-based problem behaviours were associated with a limited trajectory of improvement in home-based problem behaviour. These results are discussed with regard to implications for treatment, research methodology, policy and further studies.
