    For the last several decades, education reform has focused on closing achievement gaps between affluent, white students and their less privileged peers. One promising area for addressing achievement gaps is through promoting students’ non-cognitive skills (e.g., self-discipline, persistence). In the area of non-cognitive skills, two interventions – growth mindset and stereotype threat – have been identified as promising strategies for increasing students’ academic achievement and closing achievement gaps. This dissertation explores the use of growth mindset and stereotype threat strategies in the classroom, as a form of academic intervention. Paper 1 examines the extant evidence for growth mindset and stereotype threat interventions. Paper 1 used a systematic review and meta-analysis to identify and analyze 24 randomized controlled trials that tested growth mindset and stereotype threat interventions with middle and high school students over the course of one school year. Results from meta-analysis indicated small, positive effects for each intervention on students’ GPAs. Findings highlight the influence of variation among studies and the need for additional research that more formally evaluates differences in study characteristics and the impact of study characteristics on intervention effects. Paper 2 explored middle school students’ perceptions of teacher behaviors related to growth mindset and stereotype threat theories. Paper 2 used qualitative analysis of data from 9 focus groups with 44 middle school students in 3 rural, low income middle schools. Emergent themes included participants’ beliefs that all students are smart, that some teachers feel that certain students are smarter than others, and that students feel smartest when their teachers provide instrumental support and show emotional care. Findings highlight the capacity for middle school students to observe concepts like ability, identity and stereotypes in their teachers’ behavior and the resulting impact on their motivation and beliefs about the nature of intelligence. Paper 3 explored teacher strategies to implement growth mindset and stereotype threat theories in the classroom. Paper 3 used qualitative analysis of classroom observations and individual interviews with 9 middle school teachers in a rural, low income school. Findings include a theme related to teachers’ support of students’ productive struggle, in part by allowing students to resubmit assignments and retake assessments. Findings also indicate the potential for unintended consequences of implementing growth mindset and stereotype threat theories, as teachers reported that “retakes” also had the potential to demotivate students.Doctor of Philosoph

    Evaluation of parameter and model uncertainty in simple applications of a 1D sediment transport model

    2011 Fall.Includes bibliographical references.This paper aims to quantify parameter and model uncertainty in simulations from a 1D sediment transport model using two methods from Bayesian statistics. The first method, Multi-Variable Shuffled Complex Evolution Metropolis - Uncertainty Analysis (MSU), is an algorithm that identifies the most likely parameter values and estimates parameter uncertainty for models with multiple outputs. The other method, Bayesian Model Averaging (BMA), determines a combined prediction based on three sediment transport equations and evaluates the uncertainty associated with the selection of a transport equation. These tools are applied to simulations of three flume experiments. Results show that MSU's ability to consider correlation between parameters improves its estimate of the uncertainty in the model forecasts. Also, BMA results suggest that a combination of transport equations usually provides a better forecast than an individual equation, and the selection of a single transport equation substantially increases the overall uncertainty in the model forecasts

    The unique and interactive effects of parent and school bonds on adolescent delinquency

    Parent and school bonds are protective against delinquency. This study used longitudinal data and multilevel Poisson regression models (MLM) to examine unique and interactive associations of parent and school bonds on youth delinquency in a sample of rural adolescents (n = 945; 84% White). We investigated whether youth sex or transitioning to a new middle school moderated the linkages between parent and school bonds and later delinquency. Results indicated reduced delinquency was associated with positive parent and school relationships. Parent and school bonds interacted such that linkages between parent bonding and youth delinquency were stronger when youth also had high school bonding – suggesting an additive effect. However, interactive effects were only found when youth remained in the same school and became nonsignificant if they transitioned to a new school. Findings support prior evidence that parent and school bonds – and their interaction – play a unique role in reducing delinquency

    A presente investigação busca compreender o renovado interesse das pesquisas realizadas no âmbito da metrópole paulista com respeito à produção de identidades e aos mecanismos que operam nas circulações com base em territórios de experimentação sexual. O trabalho evidencia a partir de questões que emergem no presente as dinâmicas interativas, as vivências e as representações dos usos da sexualidade entre homens que gostam de outros homens na cidade de São Paulo entre as décadas de 1950 e 1970. Observam-se as relações sociais entre “homossexuais” nessa cidade e sua ampla ligação com redes “normais” e “marginais” de interação social. Esse período caracteriza-se pela ampliação dos lugares de sociabilidade, das categorias identitárias e dos atos políticos

Implementation of accurate passing is main point of team work to take control over the game and to minimalise human mistake in passing to each player

    Using advanced quantitative methods to study the prevention of social problems

    Get PDF
    Social work has embraced prevention as one of its grand challenges-recognising the need to understand risk and protective factors for social problems that, if addressed, may prevent social disadvantage and mental health problems from occurring. To best study prevention, social workers must become fluent in understanding and using advanced methodologies that illuminate developmental processes, depict individual and subgroup differences, and rule out potential confounds so as to shed light on important risk and protective factors. The purpose of this article is to provide a simple introduction to four advanced methods: latent growth curves (LGM), mediation models, latent class/profile models and propensity score models. Latent growth curve models are helpful for understanding changes in the developmental course of a risk factor over time. Mediation models are useful tools for understanding how risk and protective factors may affect outcomes. Latent class and latent profile models allow researchers to understand how combinations of risk factors may be linked to youth outcomes. Propensity score models allow researchers to reduce the effects of selection bias on their estimates of the relationships between risk factors and outcomes. We discuss the research questions appropriate for each type of model, the type of data required, and the strengths and weaknesses of each approach. We also include suggestions for further reading

    Do Artigo 475 do Código de PRocesso Civil Brasileiro

    Get PDF
    Neste trabalho analisamos o artigo 475 do Código de Processo Civil Brasileiro (CPC). Esse dispositivo de lei assegura ao Estado, observada a sua forma como Fazenda Pública, o privilégio de ter submetidos quase todos os processos judiciais em que tenha figurado como parte, e sucumbido, ainda que parcialmente, a uma espécie de revisão do mérito por um segundo grau de jurisdição. Convencionou-se, então, chamar, nesses casos, a remessa obrigatória dos autos à Instância Superior de reexame necessário, não obstante o emprego de outros termos análogos. O referido instituto de Direito é objeto de enfoques divergentes tanto sob a ótica da doutrina processualista civil quanto segundo a visão de nossos magistrados, o que suscita debates acalorados acerca de seus aspectos mais peculiares. Trata-se, ademais, de tema que remonta à época da influência autoritária do Estado, que, hodiernamente, contrasta com um sistema normativo-jurídico de predominância dos direitos e garantias fundamentais. Apresentamos também um estudo sucinto acerca de tal instituto, proporcionando ao leitor fácil identificação e localização do tema no universo do Direito Processual Civil
