▼ Objective: To evaluate the long-term development of patients with a cochlear implant of the University Medical Centre in Utrecht; with regard to three potential predictive factors: severity of preoperative hearing loss, duration of preoperative deafness and cause of deafness (the ‘bony disorders’ meningitis and otosclerosis vs. all other causes of deafness).
Study design: Retrospective longitudinal clinical study. Predictors of speech perception, after cochlear implantation surgery, included preoperative hearing loss, duration of deafness and effect of a bony disorder as cause of deafness (meningitis or otosclerosis); with use of
Multi-
Level Modeling analysis.
Patients: 247 adult patients with a cochlear implant.
Interventions: Unilateral multichannel cochlear implantation.
Main outcome measures: Postoperative speech perception (CVC) scores.
Results and conclusion: Perception of CVC words after cochlear implantation is significantly predicted by duration of deafness, preoperative hearing loss and presence or absence of a bony disorder as cause of deafness. There is no effect of interaction of these prediction variables, nor among themselves nor with the time predictors (=duration of implant use). The development of speech perception over time is best described by a linear and a negative quadratic growth model. As
Multi-
Level Modeling has been demonstrated in previous studies to be more powerful in hypothesis testing than other analysis tools, our unexpected result of cause of deafness being a significant predictor of speech perception might be due to the sensitivity of the
Multi-
Level Modeling method.

▼ Purpose: The understanding of sociodemographic variables and drug court completion is well documented in the drug court literature, but the application of theoretical predictors is often neglected, leading to a gap in theory and practice. To fill this gap, this study examined the utility of social support theory in explaining the differences between those who complete the drug court program and those who fail to do so. Using Cohen’s definition, social support was conceptualized as social networks, supportive behaviors, and perceived support.
Methods: Participant survey data and drug court data from the National Institute of Justice’s
Multi-Site Adult Drug Court Evaluation (MADCE) was used to construct seven scales of social support that proxy the Index of Socially Supportive Behaviors (ISSB) and Multidimensional Scale of Perceived Social Support (MSPSS). Several random-effect,
multi-
level logistic models were used to calculate the probability of drug court completion, controlling for participant and drug court
level effects. There were two hypotheses: (1)
Social support is positively associated with drug court completion, and (2)
drug court completion varies by the type of social network and the type of supportive behavior.
Results: Consistent with Cohen’s hypothesis and previous empirical research, the combination of informal and formal social support, including supportive behaviors and perceived social support, significantly predicted drug court completion at 18-months. Formal expressive and formal perceived social support were correlated with completion, even when
level-2 programmatic controls were added to the models. However, formal instrumental social support did not predict completion. Likewise, expressive, instrumental, and perceived informal social support from family remained insignificant throughout all models. Suggestions for implementing changes in the drug court model based on these results are discussed.

▼ Child maltreatment touches almost 700,000 children annually. The effects of child maltreatment range from micro-
level consequences, such as behavior problems and mental health issues, to mezzo-
level consequences, such as increased child welfare worker caseloads and overcrowding residential facilities, to macro-
level consequences, such as increased costs and policy implications. Data from the National Survey of Child and Adolescent Well-Being (NSCAW) were analyzed to examine the factors that impact child behavior in children who have been reported to child protective services (CPS) as a result of child maltreatment. The model investigated the influence of child, caregiver, and environmental factors on child behavior problems over six years among a nationally representative sample of children age 2-18. Methods: A longitudinal multivariate multilevel model was estimated utilizing MLwiN with a three-
level nested structure. The model examined individual differences in 4,997 child behavior problems over six years, testing both time-variant and time-invariant predictors measured during four time periods. Results: Following the estimation of six multivariate multilevel models, results indicated several statistically significant predictors at the child
level (i.e., gender, race, age, social skills, maltreatment type, exposure to violence, physical and cognitive health), caregiver
level (i.e., age, education, marital status, number of children in the home, number of changes in caregivers, permanent caregiver, physical health, domestic violence, social support, and perception of neighborhood), and environmental-
level (i.e., percentage of single parents, access to social services, percentage of white population) on at least one of the dependent variables. Additionally, interaction effects were tested and a few proved to be statistically significant predictors of child behavior problems as well. Conclusions: Children differ in terms of how they respond to maltreatment and other life events or situations. It is imperative that interventions be individualized to target specific issues and reduce specific behavior problems. Results indicated that improving child social skills and increasing caregiver social support may be key in reducing child behavior problems. Both practice and policy implications are discussed as well as recommendations for future research.

▼ This study analyzes resource allocation within schools, and it is one of the first in the literature to analyze the equity of monetary resources at the individual student
level. The study calculates teacher resource expenditures (TREs) per pupil by allocating teacher salaries to individual students for each high school student in a large urban public school district. Next, the study compares the degree of within-school variation in per-pupil TREs to the variation between schools and concludes that the variation within schools is much larger than the variation between schools. The study then uses Berne and Stiefel's (1984) equity evaluation framework and develops an analytic approach that is appropriate for conducting a within-school equity analysis of per-pupil TREs. The findings indicate that inequities in the allocation of teacher salaries at the student
level do exist. Specifically, the study finds violations of horizontal equity, vertical equity for low-income students, and equal opportunity for students of differing achievement levels. These findings also suggest that district leaders may be unaware of how resources are ultimately allocated to students.
This study also evaluates the equity of the within-school allocation of specific resources to identify if resources are equitably allocated in academic courses that are critical for academic success. This study evaluates the equity of the allocation of class size, teacher experience, and social capital in students' English and math courses only as well as the number of advanced placement (AP) courses taken by students, which indicates access to rigorous curricula. In analyzing the equity of these specific resources within each school in the district, this study determines if multiple resource advantages or disadvantages exist for some students.
Findings indicate that multiple resource inequities may exist for low-performing, low-income, and minority students. Further, the study finds that schools with greater socioeconomic and racial diversity have more occurrences of within-school resource inequities for low-income and minority students than schools with homogeneous student populations. The study is among the first to analyze the equity of the within-school allocation of multiple resources simultaneously to gain a better understanding of whether students in the same school receive equitable resources.

▼ School Based Probation programs provide intensive supervision for juvenile probationers by placing probation officers in high schools. However, they have yet to undergo rigorous evaluation. Previous evaluations suffered from methodological flaws and have presented inconsistent findings. The state of Maryland began its SBP program, called Spotlight on Schools (SOS), in the 1990's. It is now used in many schools throughout the state. SOS has never been formally assessed. This dissertation presents results from a quasi-experimental non-equivalent group study examining the recidivism rates of students in schools with and without this probation program. I address the flaws of previous evaluations by using two statistical methods. First, I use
multi-
level modeling to predict school
level recidivism while controlling for statistically relevant individual
level and school
level characteristics. Second, I use survival analysis to determine if juveniles on SBP experience a longer time in the community before recidivism. These analyses are supplemented with interviews of school principals and probation officers. Results from the
multi-
level modeling and survival analysis indicate that school participation in the SOS program is not significantly related to likelihood of recidivism or the seriousness of recidivism. Seven of the eight outcome variables assessed in this evaluation are not significantly related to participation in the SOS program. This study joins a long list of intensive supervision evaluations that suggest that these programs have no significant impact on juvenile recidivism.

▼ Drawing from resource-based theories of organizational performance outcomes, the current study examined how the interplay between more intangible or psychological variables predicts an employee’s understanding of and motivation to contribute
to company growth. The sample consisted of N=21,497 employees at a Fortune 500 company and spanned 55 regions/countries. Multilevel structural equation modeling was used to assess the relationship between manager relations, affective commitment, and
perceptions of compensation in predicting growth. Affective commitment mediated the relationship between manager relations and growth at the individual level but the model did not reproduce these results at the group level. Theoretical and practical
implications of these findings are discussed.

▼ Nous abordons dans cette thèse un problème important en simulation multi-agent pour l'étude des systèmes complexes: celui d'assembler de multiples expertises par une approche multi-niveau. Alors que les approches existantes considèrent habituellement la vue d'un seul expert principal sur le système, nous proposons d'utiliser une approche multi-niveau pour intégrer plusieurs expertises sous la forme d'agents de différents niveaux d'abstraction. Nous montrons qu'il est ainsi possible de rester proche des concepts manipulés par les différents experts (ce qui permet de faciliter le processus de validation dans leurs domaines respectifs) et de combiner les différents niveaux de ces concepts, de manière à ce que chaque expert puisse comprendre les dynamiques des éléments liés à son domaine. Nous proposons le méta-modèle SIMLAB basé sur une représentation unifiée des concepts par des agents pouvant s'influencer les uns les autres dans différents axes et différents niveaux. Ce travail est concrétisé dans le cadre de l'étude de l'activité humaine en relation avec la consommation électrique. Il s'agit là d'un exemple typique de système complexe nécessitant de multiples expertises issues de différents domaines tels que l'ergonomie, l'énergétique, la sociologie, la thermique, ... Dans ce contexte, nous présentons ensuite la mise en oeuvre de notre approche dans la plate-forme SMACH de simulation des comportements humains et nous décrivons un ensemble d'expérimentations illustrant les différentes caractéristiques de notre approche. Nous montrons enfin la capacité de SIMLAB à reproduire et à étendre en simulation une étude réalisée sur le terrain de gestion de la demande énergétique.
The purpose of this work is to tackle a key problem in the study of complex systems when using multi-agent simulation: how to assemble several domains of expertise with a multi-level approach. While existing approaches usually consider the viewpoint of a unique main expert, we propose to use a multi-level model to integrate the multiple domains of expertise embodied in agents located at different abstraction levels. In this work, we show that it is possible to both stay close to the concepts manipulated by the experts (for the sake of the validation process in the domain of each expert) and combine the levels of those concepts. That way, each expert can easily understand the dynamics of the components related to their domain.We present SIMLAB, our meta-model based on a unified representation of the concepts using agents. Each agent can influence the others on different axes and levels. This work is materialised in a study of human activity in relation to electrical consumption. It is a typical example of complex system which requires many domains of expertise such as psychology, energetics, sociology, heat science, … In this context, we present the implementation of our approach in SMACH, a simulation platform of human behaviours. We Then describe several experiments to illustrate the characteristics of our approach. Finally, we show how SIMLAB can…

▼ Traditional object-oriented programming languages only support two logical domain classification levels, i.e. classes and objects. However, if the problem involves more than two classification levels, then to model a
multi-
level scenario within two classification levels, a mapping approach is required which introduces accidental complexity and destroys the desirable property of “direct mapping”. Therefore “
Multi-
level modeling” was proposed. It supports an unbounded number of classification levels, that can support “direct mapping” without introducing accidental complexity. Many supporting features have been proposed for “
multi-level”
modeling such as “deep instantiation”, potency, clabjects, etc. To date most of the research effort was focusing on the entities (clabjects), while the relationships between entities were receiving much less attention and remained under-explored.
The “Melanee” tool was developed to support
multi-
level modeling both for academics and practitioners. “Melanee” supports an unbounded number of classification levels for domain
modeling and it treats relationships like clabjects. It mainly supports “constructive modeling” by creating models using a “top-down” approach, whereas “explanatory modeling”, which is creating models using “bottom-up” approach, is not well supported and lacks support to ensure the integrity of the created models. Hence, to further explore relationships in
multi-
level modeling and to provide a better
modeling environment, there are two main focuses in this thesis: First, based on existing, I further explore relationships between entities and extend the LML (
Level Agnostic
Modeling Language) supported by Melanee accordingly. Second, I extend Melanee’s functionality to support “explanatory modeling”.
Considering that Melanee is an open source tool I first discuss Melanee’s structure and its principles in order contribute to future extensions to Melanee. The knowledge of Melanee is currently known by its principle developer, Ralph Gerbig, with whom I had contacts in the beginning phase of the “deep-connection” development for advices. Next I use the work proposed in the paper “A Unifying Approach to Connections for
Multi-
Level Modeling” by Atkinson et al. as a foundation and stepping stone, to further explore relationships between entities. I extended Melanee to support the “Deep-connections” feature by adding potency to connections and their monikers, and further allow connections to have “deep-multiplicities”. I developed these features, as well as respective validation functions to ensure the well-formedness of models.
Then I extended LML so that user-specified type names can be used to indicate the names of types for clabjects. Instead of relying on modelers to fully manually define type- of classification relations between different levels, I introduce “connection conformance” and “entity conformance” to introduce classification support to Melanee. Potentially matching types are calculated and ordered per their matching scores. Respective suggestions to modelers…

▼ Diagnosis and treatment for cancer may increase experiences of stress among breast cancer survivors (BCS) by sensitizing individuals to changes in body image. Body-related self- conscious emotions may be modifiable sources of such stress, and moderate-to-vigorous physical activity (MVPA) may moderate this association. This study examined these associations using an experience sampling method. Twenty women provided measures of body-related emotions and psychological stress six times per day for seven days, and wore accelerometers to measure MVPA. Multilevel modeling was used to test for day-level time-varying predictors of psychological stress. Within-person daily variability in body-related guilt positively predicted within-person daily variability in stress. Body-related shame and pride were not significant predictors of stress and MVPA did not moderate the effect. The time by MVPA interaction with psychological stress was significant. Based on these results, body-related emotions and MVPA are important to target in interventions committed to reducing BCSâ experiences of psychological stress.

▼ The concept of “entrepreneurial culture” has existed for decades, described as an organizational culture embodying and championing entrepreneurial characteristics and attributes. These have included risk-taking, innovation, and creativity; the elements one would expect to see among entrepreneurs as individuals. The literature suggests that entrepreneurial culture is related to a number of positive organizational outcomes, such as generating new business and improving firm performance.
Despite years of entrepreneurial culture discussion, however, it remains a relatively ambiguous theoretical construct. Numerous perspectives have emerged describing the phenomenon and the concept, yet it remains unfocused and equivocal. Different definitions and sets of characteristics and attributes describe the concept inconsistently; empirical applications use inconsistent measures. Collectively, these theoretical deficiencies mean that despite the inherent value and interest in the subject, knowledge accumulation has been difficult.
This thesis addresses these deficiencies from both a conceptual and empirical perspective to answer the question: what is an entrepreneurial culture? To more clearly articulate the connection with entrepreneurship, I develop a new definition of the construct based around the broader concept of opportunities. Synthesizing the core characteristics and attributes of entrepreneurial culture, I propose a multi-dimensional theoretical model.
To empirically validate this model, I adopted a multi-method approach. I interviewed 12 entrepreneurs of Canadian small and medium-sized enterprises, to explore and expand on these conceptual dimensions. I generated a series of survey items to measure these dimensions and tested them with 45 doctoral student raters for content validity. A final questionnaire was developed and then deployed to 41 organizations, collecting data from 790 individual employees. The model was tested using multi-level structural equation modeling techniques.
The results of this study are a validated instrument to measure this new, clarified entrepreneurial culture construct. This study is an important step in understanding the nature and form of entrepreneurial culture as a firm-level construct and ways in which it might be measured. This conceptualization of entrepreneurial culture provides a springboard for future theorizing and research. This research helps generate important new insights into how organizational cultures can become more entrepreneurial, an exciting prospect for a diverse array of organizations.

▼ We assess the daily relationships between
three functional coping strategies and positive and negative affect
while accounting for the individual?s cognitive appraisal of their
encountered stressor, assessed by measuring the severity and
controllability of the encountered stressor. We collected 56 days
of daily-data from a later-life cohort (N = 230; Age 61 ? 87; M =
72.7; SD = 5.0) assessing affect, the most bothersome event
experienced that day, and which coping strategies they used to cope
with that event.
Multi-
level modeling allowed us to explore and
compare the between- and within-person effects. Daily Altering the
Situation related to lower negative affect and higher positive
affect. This coping strategy buffered the impact of stress severity
on negative affect. High use of this coping strategy mitigated
negative affect less in response to highly controllable stressors
compared to low use of this strategy. Daily Altering the Meaning
related to higher negative and higher positive affect. The mean
effect of Dispelling the Negative Effects of stress related to
higher negative affect. Findings illustrate that certain coping
strategies target affective levels differently. The effectiveness
of Altering the Situation partly depends on aspects of the
encountered stressor.

▼ Increasing amounts of data, generated by electronic sensors from various sources that include travelers, vehicles, infrastructure and the environment, referred to as “Big Data”, represent an opportunity for innovation in transportation systems and toward achieving safety, mobility and sustainability goals. The dissertation takes advantage of large-scale trajectory data coupled with travel behavioral information and containing 78 million second-by-second driving records from 100 thousand trips made by nearly four thousand drivers. The data covers 70 counties across the State of California and Georgia, representing various land use types, roadway network conditions and population. The trajectories cover various driving practices made by vehicles of varied body types as well as different fuel types including conventional vehicles (CVs) consuming gasoline, hybrid electric vehicles (HEVs), battery electric vehicles (BEVs), diesel vehicles and other alternative fuel vehicles (AFVs). The dissertation establishes a framework for the research agenda in instantaneous driving behavior studies using the large-scale trajectory data. The dissertation makes both theoretical and empirical contributions: 1) Developing measures for driving volatility in instantaneous driving behaviors; 2) Understanding correlates of driving volatility in hierarchies & developing applications using large-scale trajectory data.
Before using second-by-second trajectories, a study, answering research questions concerning the relationships between data sampling rates and information loss, was conducted. Then, a study for quantifying driving volatility in instantaneous driving behaviors was presented. “Driving volatility”, as the core concept in the dissertation, captures extreme driving patterns under seemingly normal conditions. After that, the dissertation presents a study on exploration of the hierarchical nature of driving volatility embedded in travel survey data using multi-level modeling techniques, and highlights the role of AFVs in travel. Last, the dissertation presents a study for customizing driving cycles for individuals using large-scale trajectory data, given heterogeneous driving performance across drivers and vehicle types. The customized driving cycles help generate more accurate fuel economy information to support cost-effective vehicle choices. The implications of the findings and potential applications to fleet vehicles and driving population are also discussed in the dissertation.

Epidemiologic Approaches to Understanding Gonorrhea Transmission Dynamics and the Development of Antimicrobial Resistance.

▼ Globally, the incidence of infection caused by Neisseria gonorrhoeae is the second highest among the bacterial sexually transmitted infections. In Canada, declining rates during the 1990s suggested progress toward curbing gonorrhea; however, those have been increasing since 1999, with rates in Saskatchewan among the highest in the country. Infection can cause serious complications in men and women, and reported resistance to third-generation cephalosporins could lead to potentially untreatable infections. Increased understanding of gonorrhea transmission dynamics, sexual networks, and predictors of antimicrobial resistance development is needed to inform the development of improved approaches to prevention and treatment.
The research presented herein draws upon data from Shanghai, China, and Saskatchewan, Canada, to compare and contrast varying epidemiologic approaches to enhancing understanding of gonorrhea in the two settings. Using traditional statistical approaches,
multi-
level statistical
modeling, social network analysis, and dynamic simulation
modeling, questions related to sexual behavior, partner presentation, and antimicrobial resistance development are explored. Each technique is evaluated for its potential contribution to overall understanding of the issues related to the ongoing gonorrhea epidemic, globally, and in Saskatchewan.
The relative strengths and limitations of the application of the analytical approaches in the different settings are described. Socio-demographic characteristics provided useful indicators of antimicrobial resistant infection among patients with gonorrhea from Shanghai. Further, socio-demographic characteristics were also useful for predicting presentation of a partner for testing and treatment and the use of condoms during intercourse, among this study population. In Saskatchewan, socio-demographic characteristics were useful in predicting coinfection with gonorrhea and chlamydia at the time of diagnosis as well as repeat infection with gonorrhea. Social network analysis of the Saskatchewan dataset provided little additional understanding of the gonorrhea epidemic in the province. This result was largely related to how STI data are collected and stored in the province. The utility of dynamic simulation
modeling to investigate the potential impact of antimicrobial resistance in Saskatchewan was also limited due to the same data constraints. However, the insight gained from the model building process and findings from the working model did offer a starting point for conversations around the best ways to postpone the development of antimicrobial resistance in N. gonorrhoeae in Saskatchewan, as well as contribute additional information about how the ways in which STI data are collected and stored in the province considerably restrict the applicability of otherwise powerful epidemiologic tools.
With persistently high rates of disease transmission, and the threat of untreatable infections due to antimicrobial resistance, N. gonorrhoeae remains a substantial public health threat…

▼ Les bétons sont des matériaux composites à la microstructure complexe et constitués de phases dont le contraste des propriétés physiques et mécaniques peut être très grand. Ces matériaux posent des difficultés aux approches macroscopiques lorsqu'il s'agit de maîtriser leurs comportements effectifs comme celui du fluage. Malgré ces difficultés, EDF doit se doter d'outils permettant de modéliser de façon prédictive l'évolution des bétons des ouvrages en service ou de prescrire lecahier des charges des bétons de nouvelles installations. Ayant pour objectif de contribuer à la résolution de ce problème, ce travail de thèse développe des méthodes numériques
multi échelle pour le calcul des structures constituées de matériaux fortement hétérogènes élastiques ou viscoélastiques. Plus précisément, ce travail de thèse comporte trois parties. Dans la première partie, nous nous intéressons à un composite constitué d'une matrice élastique renforcée par des inclusionsélastiques dont les formes géométriques peuvent être quelconques et dont la fraction volumique peut être importante. Pour modéliser ce matériau composite, une première approche numérique consistant à combiner la méthode des éléments finis étendus (XFEM) standard et la méthode "
level-set" (LS) classique est d'abord utilisée. Nous montrons que cette première approche numérique, qui apparaît naturelle, induit en fait plusieurs artefacts numériques non rapportés dans la littérature, conduisant en particulier à une convergence non optimale par rapport à la finessedu maillage. Par suite, nous élaborons une nouvelle approche numérique (μ-XFEM) basée sur la description des interfaces par des courbes de niveaux multiples et sur un enrichissement augmenté permettant de prendre en compte plusieurs interfaces dans un même élément. Nous démontrons au travers des comparaisons et exemples que la convergence est améliorée de manière substantielle par rapport à la première approche numérique. Dans la deuxième partie, nous proposons une nouvelle méthode pour calculer les déformations différées des structures composées de matériaux hétérogènes viscoélastiques linéaires. Contrairement aux approches proposées jusqu'à présent, notre méthode opère directement dans l'espace temporel et permet d'extraire de manière séquentielle le comportement homogénéisé d'un matériau hétérogène viscoélastique linéaire. Concrètement, les composantes du tenseur de relaxation effectif du matériau sont d'abord obtenues à partir d'un volume élémentaire représentatif et échantillonnées au cours du temps. Une technique d'interpolation et un algorithme implicite permettent ensuite d'évaluer numériquement la réponse temporelle du matériau par le biais d'un produit de convolution. Les déformations différées des structures sont enfin calculées par la méthode des éléments finis classique. Différents tests sont effectués pour évaluer la qualité et l'efficacité de la méthode proposée, montrant que cette dernière permet d'avoir un gain en temps de l'ordre de plusieurs centaines par rapport aux approches de type éléments…

▼ ¿Hay relación entre la participación política y la satisfacción individual con la vida? La idea de que la participación política hace que la gente esté más satisfecha con su vida ha sido un tema debatido durante mucho tiempo. No obstante, la investigación empírica existente no ha sido muy exitosa en demostrar que dicha relación existe, mientras que algunos estudios muestran que en su lugar es la satisfacción individual con la vida la que tiene un impacto en la participación política. Esta tesis doctoral se centra en el tema de la causalidad entre participación política y satisfacción individual con la vida. Los tres primeros artículos están dedicados a afirmar la existencia de una relación causal entre participación política y satisfacción con la vida. Utilizando datos de panel, no se ha encontrado evidencia de dicha relación. Dados estos resultados, esta tesis pasa a preguntarse si la conexión entre participación política y satisfacción con la vida está condicionada por el contexto político y el tipo de participación política. Utilizando datos transversales, se demuestra que hay un efecto de la participación política en la satisfacción con la vida, contingente con el tipo de ley de participación y condicionado en el nivel más alto por la apertura del sistema político.

▼ Solid models traditionally use boundary-representation (B-rep) to define and model their geometry. However, performing modeling operations such as Boolean operations or computing point membership classification with B-rep is computationally intensive, since B-reps do not have volumetric information. Voxelized representations, on the other hand, can be extended to include volumetric information of solid models. However, in order to use voxelized representations for solid modeling, efficient methods for voxelizing a B-rep solid model needs to be developed. In this thesis, GPU-accelerated methods are presented for creating and rendering a multi-level voxelization of a solid model that can be used along with the existing B-rep for modeling operations. Two GPU-accelerated algorithms are described; one for creating a multi-level voxelization given a B-rep of a solid model and another for ray casting to render the multi-level voxelization of the solid model. Compact and flat data structures are described that can be used to store the multi-level voxelization data and can be efficiently retrieved in parallel using GPU-algorithms for rendering and modeling operations. The GPU-accelerated multi-level voxelization method can generate models with an effective voxel count of up to 8 billion voxels. In addition, the GPU voxelization algorithm is more than 40x faster than the CPU implementation in generating the voxelization. Finally, we outline a few applications for the hybrid representation, which include fast point-membership classification, volume computation, and collision detection.

▼ Guided by Bronfenbrenner's ecological theory of human development and social capital theory, this study examined the pathways that link childhood neighborhood assets, adolescent family and school social capital, and civic involvement in emerging adulthood. Three waves of data from the National Longitudinal Study of Adolescent Health (Add Health) and multi-level structural equation models were used to examine the hypotheses set forth in this study. Findings revealed that adolescent family and school social capital were shown to have unique influences on reports of civic involvement in emerging adulthood, and the effect of childhood neighborhood assets was mediated by the degree of family cohesion in the adolescents' home. Moreover, the expression of neighborhood, family and school pathways to civic involvement in emerging adulthood were found to differ by neighborhood groups, gender and race. These results help to illustrate the importance of examining multi-contextual influences on civic involvement in emerging adulthood. In addition, the results from this study can inform efforts to strengthen the theory of adolescent civic engagement and policies on how to educate youth and communities on civic engagement and its benefits.

▼ Researching children’s and adolescents’ emotions from their own perspectives possesses special requirements for the data collection tools used. In this study, children’s and early adolescents’ emotions were investigated using a mobile diary method. The article describes and evaluates this data collection method and presents empirical results on fluctuation in the emotions of children and adolescents (n = 60, aged 7–14 years). The data, in the form of short text messages, were collected over one week. Every evening, children received seven questions on their emotions. Multilevel
modeling was used to analyze the data. The results illustrate the potential of the mobile diary method with children and early adolescents. The data showed a two-factor structure, indicating that the mobile diary method was able to reveal the underlying dimensions of positive and negative emotions. The study also showed that daily variation in emotions along with systematic differences between participants in their emotional experiences (related to, e.g., the form of the family) can be captured using the method.

▼ Students cannot benefit from what they do not experience. Multiple reasons exist for why an intervention may not be delivered as it was designed. In this era of educational accountability and limited dollars to go around, understanding how an intervention is delivered in the classroom is key to understanding program outcomes. In order to assess whether a program has been implemented as intended, an assessment of fidelity is needed. However assessing fidelity is complex given varying conceptual interpretations, which then fosters inconsistent application of methods to measure the construct. Additionally the methods for validating fidelity measures are still unclear. The current study evaluated the reliability and validity of the student Instructional Pedagogical (10 items) and Instructional Student Engagement (15 items) scores for use in assessing teachers' fidelity of implementation on the participant responsiveness component of fidelity. The sample consisted of over 5,000 responses from students and 242 teachers in Mathematics and Science across three school districts and 41 schools to an online fidelity of implementation questionnaire. Given that students were nested within teachers, the data structure was multilevel, which warranted that the psychometric analyses be conducted using a multilevel framework. Instructional Pedagogy is represented by 10 items that measure three factors. Multilevel confirmatory factor analysis was used to test a two-level model that had three factors at the student-level and three factors at the teacher-level. Instructional Student Engagement is represented by 15 items that measure four factors. Multilevel confirmatory factor analysis was used to test a two-level model that had four factors at the student-level and four factors at the teacher-level. The psychometric results of the student questionnaire assessing the student engagement components of fidelity were mixed. Support for the factorial validity of the multilevel student models was mixed, with model fit indicating that some of the measured variables did not load strongly on their respective factors and some of the factors lacked discriminant validity. Lastly, the correlations between students' and teachers' scores for both the observed and latent variables (ranging from -.15 to .72 in math; -.07 to .41 in science) displayed limited convergent validity.

▼ Demonstrating a direct link between teacher education programs and student growth is, to say the least, complex. Yet, using value-added systems as a means of holding teacher preparation programs accountable for the effectiveness of their graduates is a growing trend. However, few quantitative studies linking TPPs with the effectiveness of their graduates exist. The availability of student test scores linked to specific teachers in administrative databases makes it possible to use value-added
modeling to obtain estimates of teacher effects. Only recently have researchers tapped into this expanding volume of data in an attempt to examine Teacher Preparation Programs as variables of student achievement. This study uses methodologies developed in the early stages of the Value-Added Teacher Preparation Program Assessment Model developed in Louisiana in 2006 as a guide. Using the HLM 7.0 software package, a statistical model was developed to determine if it were feasible to conduct an analysis using data from a single small school district and whether the results of such an analysis showed an impact of student characteristics and teacher experience and preparation program on student outcomes in mathematics.

▼ Existing language assessments and theories of language development assume a clear division into receptive and expressive processes. However, measurement studies provide only mixed support for this structure of language–some studies support the division of language into dual processes of expressive and receptive language while other studies conclude that language is a single process. The Preschool Language Scale – 5 (PLS-5, Zimmerman, Steiner, & Pond, 2011) is a commonly administered assessment used for diagnostic and research purposes and thus, the psychometric properties should be well-established. The PLS-5 is one of only a few assessments to cover the age range of birth to seven years old, meaning it is useful for research on longitudinal language development in addition to the recommended clinical use. This study uses PLS-5 data collected from 2014 to 2017 at urban childcare centers serving primarily low SES African American children to address two research questions: 1) to what extent does a confirmatory factor model support the division of language into receptive and expressive language components? 2) what does this structure of language say about how students grow in preschool? The results of the longitudinal confirmatory factor analyses suggest that language is a general construct rather than divided by modality, and thus the total language score on the PLS-5 may be preferable to interpreting the individual subscale scores of Expressive Communication and Auditory Comprehension.

▼ Over the past ten years, there has been increased use of electronic power processing in alternative, sustainable, and distributed energy sources, as well as energy storage systems, transportation systems, and the power grid. Three-phase voltage source converters (VSCs) have become the converter of choice in many ac medium- and high-power applications due to their many advantages, such as high efficiency and fast response. For transportation applications, high power density is the key design target, since increasing power density can reduce fuel consumption and increase the total system efficiency. While power electronics devices have greatly improved the efficiency, overall performance and power density of power converters, using power electronic devices also introduces EMI issues to the system, which means filters are inevitable in those systems, and they make up a significant portion of the total system size and cost. Thus, designing for high power density for both power converters and passive components, especially filters, becomes the key issue for three-phase converters.
This dissertation explores two different approaches to reducing the EMI filter size. One approach focuses on the EMI filters itself, including using advanced EMI filter structures to improve filter performance and modifying the EMI filter design method to avoid overdesign. The second approach focuses on reducing the EMI noise generated from the converter using a three-
level and/or interleaving topology and changing the modulation and control methods to reduce the noise source and reduce the weight and size of the filters.
This dissertation is divided into five chapters. Chapter 1 describes the motivations and objectives of this research. After an examination of the surveyed results from the literature, the challenges in this research area are addressed. Chapter 2 studies system-
level EMI
modeling and EMI filter design methods for voltage source converters. Filter-design-oriented EMI
modeling methods are proposed to predict the EMI noise analytically. Based on these models, filter design procedures are improved to avoid overdesign using in-circuit attenuation (ICA) of the filters. The noise propagation path impedance is taken into consideration as part of a detailed discussion of the interaction between EMI filters, and the key design constraints of inductor implementation are presented. Based on the
modeling, design and implementation methods, the impact of the switching frequency on EMI filter weight design is also examined. A two-
level dc-fed motor drive system is used as an example, but the
modeling and design methods can also be applied to other power converter systems.
Chapter 3 presents the impact of the interleaving technique on reducing the system passive weight. Taking into consideration the system propagation path impedance, small-angle interleaving is studied, and an analytical calculation method is proposed to minimize the inductor value for interleaved systems. The design and integration of interphase inductors are also analyzed,…

▼ Contexto:
Multi Level Autonomic Business Process (MABUP) é uma opção para
auxiliar no gerenciamento de processos de negócios autonômicos. Ela considera
aspectos relativos à variabilidade, compreensibilidade, escalabilidade e Requisitos Não-
Funcionais. Contudo, identificamos algumas limitações para adoção da abordagem
MABUP, entre elas a necessidade do desenvolvimento de uma ferramenta de apoio que
permita não apenas a modelagem dos processos de negócios com características
autonômicas, mas também a sua execução. Objetivo: Portanto, nesta dissertação
propomos o desenvolvimento da ferramenta MABUPTool, a partir da extensão do
framework Activiti, com o objetivo de auxiliar na adoção e compreensão da abordagem
MABUP. Método: Após o desenvolvimento da ferramenta foram feitas duas avaliações
experimentais com o objetivo de investigar a adoção da abordagem como sua
ferramenta de apoio. Os resultados obtidos são promissores uma vez que os dados
indicam que a adoção dos elementos estendidos auxilia a compreensão da abordagem
MABUP. Conclusões: Para avaliar a qualidade da ferramenta, uma avaliação de
usabilidade foi feita e os resultados indicaram que os quatro fatores analisados
(satisfação geral, utilidade do sistema, qualidade da informação e qualidade da
interface) foram alcançados com sucesso.

▼ Does state policy influence how well students are prepared to attend college? For the past 25 years, state and federal policies have focused attention on the high school curriculum with concern about whether or not students would be adequately prepared to pursue postsecondary education by the time they finish high school. Increasingly, states have adopted high school graduation requirement policies and exit exam requirements and a range of strategies to improve student outcomes but few studies have assessed whether those policies have operated in anticipated ways.
This study examines the relationship between high school graduation requirements, exit exams, average school funding per student and the cost of college and two student outcomes important to college access – high school completion and the number of courses completed in the core subjects – among public school students. I utilize the Education Longitudinal Study (ELS:2002) first follow up and transcript survey in combination with state policy indicators to examine these relationships. In an effort to account for the complex sampling design and to recognize that students are nested within schools, which operate within unique state policy environments, I employ a three-
level hierarchical linear
modeling (HLM).
The findings demonstrate that policy matters in both anticipated and unexpected ways. Students in local control states are more likely to finish high school in four years than those in graduation requirement states and those in exit exam states are less likely to finish than in non-exam states. African American students in local control states are less likely to finish high school than their White and Asian peers; a gap that does not exist in other states. In terms of course taking, students complete more courses in the core subjects in states with graduation requirement policies. State adopted graduation requirements increase the number of core courses taken but a gap exists between those attend high and low SES schools. On balance, there appear to be greater benefits to adopting state graduation requirements, but greater attention must be paid to mediate the possible influence on high school completion.

▼ Despite the developmental and clinical importance of body image during the pre-adolescent and adolescent years, there remains a dearth of information on the body image experiences of immigrant children and adolescents. This thesis represents a purposeful attempt to examine body image experiences among immigrant and ethnic minority children and adolescents in Canada and the United States (US). Specifically, the thesis integrates multiple methods (scoping reviews, qualitative interpretive description, quantitative
multi-
level modeling) and samples (clinical and population-based samples) to systematically contribute to the academic literature focusing on body image experiences among immigrant and ethnic minority children and adolescents in Canada and the US. Consisting of four conceptually related studies, this thesis makes the following methodological and conceptual contributions to epidemiological and clinical research and practice. First, the results from all four studies point to the need to develop standardized approaches for identifying and classifying immigrant and ethnic-minority children and adolescents. This will substantially increase the field’s ability to systematically characterize the nature and magnitude of body image dissatisfaction, body image distortion, and their associated outcomes among immigrant and ethnic minority children and adolescents. In addition, this systematic classification has the potential to inform the development or adaptation of universal and targeted preventative intervention strategies. Second, Study’s 1 and 2 demonstrate a clear need to further examine the constructs and experiences of acculturation and acculturative stress in relation to the body image experiences of immigrant and ethnic minority children and adolescents. The literature is unclear with respect to whether or not immigrant adolescents’ adoption of the values, behaviours and ideals of the Canadian or US culture increases their risk for body image concerns. On the other hand, we are also unclear as to whether or not immigrant adolescents’ retaining of the values, behaviours and ideals of their culture of origin may offer protection from poor body image experiences. Similarly, we are unclear about whether—and to what extent—stress as a result of adolescents’ acculturative experiences (i.e. acculturative stress) influence the onset or pervasiveness of body image concerns. Greater understanding about these constructs and processes and the extent to which they are implicated in the body image experiences among immigrant children and adolescents has the potential to inform culturally competent and targeted intervention approaches. Results from Study 3 indicate that immigrant adolescents have body image and appearance-related concerns that extend beyond what has typically been found among non-immigrant adolescents. More specifically, immigrant adolescents are concerned about the appearance of their skin (texture, complexion), their hair, their teeth, as well as other bodily features. It would be prudent for future…

▼ The examination of the relationship between ecologic
covariates and functionals related to various lung function growth
curves is of main interest in studying the long term effects of air
pollution on children's health. However, such a
modeling process
leads to several challenging and unresolved issues such as
non-linearity in the growth curves, and the correlation between and
within outcomes. In this dissertation, flexible
multi-
level
modeling techniques are proposed using penalized splines to model
longitudinal outcomes (e.g. lung functions). This new method not
only allows for the flexibility in
modeling non-linear growth
curves but also allows for joint-
modeling of the smoothing
parameter and the variance components. Second, the penalized-spline
based mixed effects model is extended by
modeling multiple outcomes
jointly via latent variables approach. Hence, this extended model
provides a way of accounting for the correlation between outcomes.
All proposed models are implemented in a Bayesian setting. These
techniques are illustrated throughout via analysis of data from the
Southern California Children's Health Study.

▼ Recent health care reform brings forth the importance
of preventive strategies such as screening. However, concerns about
the growing population and rising healthcare spending necessitate
health plans and public health policymakers to consider and
determine cost‐beneficial population‐based screening strategies.
Screening strategies often vary on compliance and, thus, result in
suboptimal cost‐benefit for the population. To achieve maximum cost
benefit, especially for screenings that often suffer low
compliance, such as Diabetic Retinopathy screening, policymakers
need to consider multi‐
level (e.g. both patient‐ and
provider‐
level) interventions to improve screening compliance. To
determine which of such interventions are cost-beneficial, many
different screening strategies need to be considered. Yet, it is
costly, impractical, and time‐consuming to do clinical trials to
test all the different screening strategies. Simulation models
provide a more cost‐ and time‐effective way to help determine
cost-beneficial screening strategies. ❧ Simulation models have been
used extensively to address cost‐benefit of screening. However,
there are shortcomings to existing models. First, they do not have
a structure that enables the evaluation of strategies that include
policies affecting compliance, even though screening compliance is
often low. Thus, strategies that include policies targeting the
improvement of compliance may be necessary to achieve maximum
cost‐benefit. Additionally, even policies not specifically
targeting compliance may affect compliance, and models evaluating
such policies without considering their impact on compliance will
under‐ or over‐estimate the policy impact. Second, current
simulation models do not have a structure that can evaluate
multi‐
level strategies (e.g. those targeting patient, providers,
and clinics) even though they are more likely to have sustained or
powerful effect than those targeting only the individual‐
level.
This research develops a generic conceptual model for screening
services that addresses the two shortcomings and then constructs
the model for the case of Diabetic Retinopathy screening to
illustrate the model. ❧ The first shortcoming is addressed by
including compliance as a mediating variable in the model, rather
than a fixed input variable as in current methods. Compliance is
influenced by patient characteristics (demographics, disease
severity, self‐care, health belief) and screening strategy used,
and in turn compliance influences disease progression and
healthcare utilization and, thus, cost and benefit of the screening
strategy. The second shortcoming is addressed by using hierarchical
simulation with nested design where policy effects are manifested
not universally but through a hierarchical structure. This enables
evaluation of the impact of policies at a higher aggregate
level
(e.g. policies that target providers) on individual (patient)
outcomes. The multi‐
level design has the benefit of taking into
account behavior at several levels and enabling the incorporation

▼ The incidence of adverse birth outcomes, such as low birth weight and preterm births, has steadily risen in recent years in Canada. Despite the fact that numerous individual and neighbourhood risk factors for low birth weight and preterm births have been identified and various person-oriented intervention strategies have been implemented, uncertainties still exist concerning the role that place and space play in determining adverse birth outcomes.
In order to succeed in producing community-oriented health policy and planning guidelines to reduce both the occurrence and inequalities of adverse birth outcomes, the research presented in this thesis provides an approach to examining the pathways of various socio-economic, environmental, and psycho-social risks to LBW and preterm births. Using a modified multilevel binary-outcome mediational analysis method, case studies are conducted within three public health units in Ontario, namely the Wellington-Dufferin-Guelph Health Unit, the Windsor-Essex County Health Unit, and the Halton Region Health Unit. Different pathways are investigated given the available data and the theoretical assumptions of three health inequality pathway models, namely the behavioural model, the psycho-social model, and the materialist model, and the geographical and planning perspectives of health inequalities. A local spatial analysis process is also used to identify spatial clusters of incidence and to assess possible associated reasons in order to support public health polices and planning in community-oriented health interventions. Using Bayesian spatial hierarchical analysis and spatial clustering analysis, local clustering of high risks of adverse birth outcomes and spatial variations of associated individual risks within the study areas are identified.
The analysis is framed around five hypotheses that examine personal vs. spatial, compositional vs. contextual, psycho-social vs. material, personal vs. cultural, and global vs. local effects on the determinants of adverse birth outcomes. The results of testing these hypotheses provide evidence to assist with multi-component multi-level community-oriented interventions. Possible improvements of current prenatal care policies and programs to reduce the spatial and social inequalities of adverse birth outcomes are suggested. Potential improvements, including early stage prenatal health education, local healthy food provision, and cross-sector interventions such as the combination of social mixing strategies with bottom-up community-based health promotion programs, are also suggested.

▼ AC and DC impedances of switching power converters are used for the stability analysis of modern power electronics systems at three-phase AC and single-phase DC interfaces. Therefore, a small-signal characterization algorithm for switching power converter, which is based on FFT, will be presented and explained. The presented extraction algorithm is general and can be used to obtain other small-signal transfer functions of arbitrary power converter switching simulation models. Furthermore, FFT algorithm is improved by using cross power spectral density functions for identification, resulting in an algorithm, which is more noise immune. Both small-signal identification algorithms are validated in simulations, and CPSD algorithm is used in experimental measurement procedure. Several wide bandwidth injection signals, among which are chirp,
multi-tone, pulse and white noise, are compared and theoretically analyzed. Several hardware examples are included in the analysis.
The second part of the dissertation will focus on the
modeling of small-signal input dq admittance of
multi-pulse diode rectifiers, providing comparison between well-known averaged value models (AVMs), parametric averaged value models (PAVM), the switching simulation model and hardware measurements. Analytical expressions for all four admittances present in the dq matrix are derived and analyzed in depth, revealing the accuracy range of the averaged models. Furthermore, a hardware set-up is built, measured and modeled, showing that the switching simulation model captures nonlinear sideband effects accurately. In the end, a
multi-pulse diode rectifier feeding a constant power load is analyzed with modified AVM and through detailed simulations of switching model, proving effectiveness of the proposed modifications.
The third part describes implementation and design of a single-phase
multi-
level single-phase shunt current injection converter based on cascaded H-bridge topology. Special attention is given toward the selection of inductors and capacitors, trying to optimize the selected component values and fully utilize operating range of the converter. The proposed control is extensively treated, including inner current, outer voltage loop and voltage balancing loops. The designed converter is constructed and integrated with measurement system, providing experimental verification. The proposed
multi-
level single-phase converter is a natural solution for single-phase shunt current injection with the following properties: modular design, capacitor energy distribution, reactive element minimization, higher equivalent switching frequency, capability to inject higher frequency signals, suitable to perturb higher voltage power systems and capable of generating cleaner injection signals.
Finally, a modular interleaved single-phase series voltage injection converter, consisting of multiple paralleled H-bridges is designed and presented. The decoupling control is proposed to regulate ac injection voltage, providing robust and reliable strategy for series voltage…

▼ Biculturalism in the Latino population in U.S. has been found to relate to positive outcomes in the literature. However, little is known about the development of bicultural adaptation. The constituent parts of biculturalism, acculturation, and enculturation were measured over several years as part of an existing longitudinal study along with several variables that held promise as predictors of acculturation and enculturation change. An additional data point for acculturation and enculturation was gathered along with other important demographic information. Change in both acculturation and enculturation was modeled revealing that acculturation and enculturation increase and decrease linearly. The trajectory for acculturation is much steeper than the trajectory of enculturation, providing support for orthogonal measurement and indicating real possibilities for interventions to increase bicultural adaptation. The best-fit model for acculturation included years in the U.S., preference for speaking English, and receptive English vocabulary. The best-fit model for enculturation included years in the U.S., preference for speaking English, and receptive English vocabulary.
