Multilevel Potential Outcome Models for Causal Inference in Jury Research

January 2015 (has links)
abstract: Recent advances in hierarchical or multilevel statistical models and causal inference using the potential outcomes framework hold tremendous promise for mock and real jury research. These advances enable researchers to explore how individual jurors can exert a bottom-up effect on the jury’s verdict and how case-level features can exert a top-down effect on a juror’s perception of the parties at trial. This dissertation explains and then applies these technical advances to a pre-existing mock jury dataset to provide worked examples in an effort to spur the adoption of these techniques. In particular, the paper introduces two new cross-level mediated effects and then describes how to conduct ecological validity tests with these mediated effects. The first cross-level mediated effect, the a1b1 mediated effect, is the juror level mediated effect for a jury level manipulation. The second cross-level mediated effect, the a2bc mediated effect, is the unique contextual effect that being in a jury has on the individual the juror. When a mock jury study includes a deliberation versus non-deliberation manipulation, the a1b1 can be compared for the two conditions, enabling a general test of ecological validity. If deliberating in a group generally influences the individual, then the two indirect effects should be significantly different. The a2bc can also be interpreted as a specific test of how much changes in jury level means of this specific mediator effect juror level decision-making. / Dissertation/Thesis / Doctoral Dissertation Psychology 2015

Planned Missing Data in Mediation Analysis

January 2015 (has links)
abstract: This dissertation examines a planned missing data design in the context of mediational analysis. The study considered a scenario in which the high cost of an expensive mediator limited sample size, but in which less expensive mediators could be gathered on a larger sample size. Simulated multivariate normal data were generated from a latent variable mediation model with three observed indicator variables, M1, M2, and M3. Planned missingness was implemented on M1 under the missing completely at random mechanism. Five analysis methods were employed: latent variable mediation model with all three mediators as indicators of a latent construct (Method 1), auxiliary variable model with M1 as the mediator and M2 and M3 as auxiliary variables (Method 2), auxiliary variable model with M1 as the mediator and M2 as a single auxiliary variable (Method 3), maximum likelihood estimation including all available data but incorporating only mediator M1 (Method 4), and listwise deletion (Method 5). The main outcome of interest was empirical power to detect the mediated effect. The main effects of mediation effect size, sample size, and missing data rate performed as expected with power increasing for increasing mediation effect sizes, increasing sample sizes, and decreasing missing data rates. Consistent with expectations, power was the greatest for analysis methods that included all three mediators, and power decreased with analysis methods that included less information. Across all design cells relative to the complete data condition, Method 1 with 20% missingness on M1 produced only 2.06% loss in power for the mediated effect; with 50% missingness, 6.02% loss; and 80% missingess, only 11.86% loss. Method 2 exhibited 20.72% power loss at 80% missingness, even though the total amount of data utilized was the same as Method 1. Methods 3 – 5 exhibited greater power loss. Compared to an average power loss of 11.55% across all levels of missingness for Method 1, average power losses for Methods 3, 4, and 5 were 23.87%, 29.35%, and 32.40%, respectively. In conclusion, planned missingness in a multiple mediator design may permit higher quality characterization of the mediator construct at feasible cost. / Dissertation/Thesis / Doctoral Dissertation Psychology 2015

Identifying Mediators of Youth Anxiety and Depression Intervention Outcomes: A Meta-Analytic Path Analysis

January 2015 (has links)
abstract: Anxiety and depression are among the most prevalent disorders in youth, with prevalence rates ranging from 15% to 25% for anxiety and 5% to 14% for depression. Anxiety and depressive disorders cause significant impairment, fail to spontaneously remit, and have been prospectively linked to problematic substance use and legal problems in adulthood. These disorders often share a high-degree of comorbidity in both clinical and community samples, with anxiety disorders typically preceding the onset of depression. Given the nature and consequences of anxiety and depressive disorders, a plethora of treatment and preventative interventions have been developed and tested with data showing significant pre to post to follow-up reductions in anxiety and depressive symptoms. However, little is known about the mediators by which these interventions achieve their effects. To address this gap in the literature, the present thesis study combined meta-analytic methods and path analysis to evaluate the effects of youth anxiety and depression interventions on outcomes and four theory-driven mediators using data from 55 randomized controlled trials (N = 11,413). The mediators included: (1) information-processing biases, (2) coping strategies, (3) social competence, and (4) physiological hyperarousal. Meta-analytic results showed that treatment and preventative interventions reliably produced moderate effect sizes on outcomes and three of the four mediators (information-processing biases, coping strategies, social competence). Most importantly, findings from the path analysis showed that changes in information-processing biases and coping strategies consistently mediated changes in outcomes for anxiety and depression at both levels of intervention, whereas gains in social competence and reductions in physiological hyperarousal did not emerge as significant mediators. Knowledge of the mediators underlying intervention effects is important because they can refine testable models of treatment and prevention efforts and identify which anxiety and depression components need to be packaged or strengthened to maximize intervention effects. Allocating additional resources to significant mediators has the potential to reduce costs associated with adopting and implementing evidence-based interventions and improve dissemination and sustainability in real-world settings, thus setting the stage to be more readily integrated into clinical and non-clinical settings on a large scale. / Dissertation/Thesis / Masters Thesis Psychology 2015

Procedural Justice and Legal Socialization Among Serious Adolescent Offenders: A Longitudinal Examination

January 2016 (has links)
abstract: Research on Tyler’s process-based model has found strong empirical support. The premise of this model is that legitimacy and legal cynicism mediate the relationship between procedural justice and compliance behaviors. Procedural justice and legitimacy in particular have been linked to compliance and cooperation and a small, but growing body of literature has examined how these factors relate to criminal offending. There remains a number of unanswered questions surrounding the developmental processes and underlying mechanisms of procedural justice and legal socialization. The purpose of this study is twofold. First, this study will build upon recent trends in the literature to examine what factors influence changes in perceptions of procedural justice and legal socialization attitudes over time. In order to do so, the effects of a number of time-stable and time-varying covariates will be assessed. Second, this study will evaluate the effects of four possible mediating measures—legitimacy, legal cynicism, anger, and prosocial motivation—underlying the relationship between procedural justice and criminal offending. This section of the study will use a multilevel mediation method to assess whether mediation occurs between or within the individual. Data from the Pathways to Desistance Study—a longitudinal study of 1,354 adolescents adjudicated of a serious offense followed-up for seven years—are used to address this research agenda. Results from this study offer three general conclusions. First, results show that perceptions of procedural justice are malleable, that is, they can change over time and are influenced by a number of factors. Legal socialization beliefs, however, demonstrate only marginal change over time, suggesting these beliefs to be more stable. Second, analyses indicate differing pathways and effects for direct and vicarious experiences of procedural justice. Finally, the multilevel mediation analyses reveal that within-individual changes in direct experiences of procedural justice remains a robust predictor of offending, regardless of the presence of mediating variables. Legitimacy was found to have the strongest mediation effect on between-individual differences in direct procedural justice, whereas anger partially mediated the effects of between-individual differences in vicarious procedural justice. This study concludes with a discussion of policy implications and avenues for future research. / Dissertation/Thesis / Doctoral Dissertation Criminology and Criminal Justice 2016

Egalitarian Socialization and Subjective Well-Being in Multiracial Individuals: A Moderated Mediation Analysis

January 2016 (has links)
abstract: Scholarly interest in racial socialization is growing, but researchers' understanding of how and when racial socialization relates to subjective well-being is underdeveloped, particularly for multiracial populations. The present study investigated the possibility that the relationship of racial socialization to subjective well-being is mediated by racial identification and that this mediation depends on physical racial ambiguity. Specifically, the proposed study used a moderated mediation model to examine whether the indirect relation of egalitarian socialization to subjective well-being through racial identification is conditional on physical racial ambiguity among 313 multiracial individuals. Results suggested egalitarian socialization was positively correlated with subjective well-being. The results provided no support for the moderated mediation hypothesis. The present study examined the complex interaction between racial socialization, racial identification, physical racial ambiguity, and subjective well-being among multiracial individuals. Despite receiving no support for the moderated mediation hypothesis, this research helped to further explicate a distinct pathway through which egalitarian socialization impacts well-being through racial identification for multiracial individuals independent of physical racial ambiguity. / Dissertation/Thesis / Doctoral Dissertation Counseling Psychology 2016

Emerging Adults and Their Helicopter Parents: Communication Quality as Mediator between Affect and Stress

January 2017 (has links)
abstract: With the establishment of the emerging adult developmental period and the rise of helicopter parents, attachment theory provides foundation for conceptualizing the continued involvement of helicopter parents in their emerging adults’ emotion regulation processes. This study utilized dyadic data from 66 emerging adult children and their helicopter parents to examine the association of helicopter parent-emerging adult communication in mitigating the associations between experiences of affect and stress. Specifically, the purpose of the present study was to use dyadic data to examine how communication within the helicopter parent-emerging adult relationship associates with emerging adults’ ability to regulate experiences of negative and positive affect. Both associations within the emerging adult and helicopter parent individually (actor effects) and how helicopter parents impact construct associations for emerging adults’ (partner effects) were considered. Two multilevel mediation models using Actor-Partner Interdependence Models were conducted to assess the relations between affect, stress, and helicopter parent-emerging adult communication quality for negative and positive affect separately. The positive direct effect between negative affect and stress was statistically significant for emerging adults, but not for helicopter parents, suggesting that, for emerging adults, higher perceptions of negative affect were associated with higher levels of stress. The direct and indirect effects for the mediation model examining actor and partner effects between negative affect, communication quality, and stress were non-significant for both emerging adults and helicopter parents. The direct effect between positive affect and stress was statistically significant for helicopter parents but not for emerging adults; however, the directionality of the significant association was positive and not as hypothesized. Finally, the direct and indirect effects for the mediation model examining actor and partner effects between positive affect, communication quality, and stress were non-significant for emerging adults and helicopter parents. Considerations for future studies examining aspects of attachment within emotion regulation for the helicopter parent-emerging adult relationship and the importance of considering relationship characteristics, such the relational characteristics of social support and conflict, are discussed. / Dissertation/Thesis / Doctoral Dissertation Counseling Psychology 2017

Christian Self-Knowledge: A Christological Framework for Undermining Dissociation through Reconciliation

Badgett, Jonathan P. 07 June 2018 (has links)
Self-knowledge unavoidably implicates and, in the end, it must presume correspondence. How, indeed, can a self even be posited in the absence of a corresponding other? While the triunity of God reveals a dialectic of unity and correspondence, the human self has ever struggled, within traditions as seemingly diverse as ancient Hellenism and the sundry schools of modern philosophy and psychology, against the presumption that “autonomous self” might not be fatally contradictory. On the other hand, with the lens of orthodox Christology properly affixed, God, self, and others may finally be seen as they truly are. Christ is the revealer of mysteries, the reconciler of God and humanity, and the One in whom all the treasures of (self-)knowledge and wisdom are found. Christian self-knowledge, then, presumes the believer’s ethical correspondence—to God-in-Christ and, through Christ, with fellow believers by means of faith expressing itself in love. When sought in Christian caregiving contexts, this Christ-mediated knowledge of self, over time, counters and undermines the countertherapeutic expression of dissociation and its ethical corollary, self-deception.

No contexto polifacético e dialógico em que se imbricam identidade e alteridade, que papel teria o futebol de várzea na mediação das diferenças locais, que maneiras de fazer sua prática interatuam e modificam o espaço e as relações? Nesse sentido, este estudo é uma fenda que se abre como possibilidade de multiplicação e interconexão inter-territórios, estabelecendo pontes entre as fronteiras. Para tanto, a partida em busca dos percursos ou trajetórias das maneiras de fazer dos times São Gonçalo Beira Rio e Milionários Futebol Clube, cobrou-nos esmiuçar, através da entrevista oral, relatos da história de vida desses dois grandes times de futebol de várzea. Conceitos sobre espaço, território, táticas e estratégias e relatos orais, entre outros, oferecem amparo teórico advindo de áreas diversas, como História Cultural, Antropologia, Sociologia, Comunicação Social, Esporte e Lazer, de maneira que servem como forma de expansão das miradas variadas, da multiplicidade das linhas que se entrecruzam e se perdem, do jogo multifacetado que faz o futebol de várzea.

Danse, émotions et pensée en mouvement : contribution à une sociologie des émotions : le cas de Giselle et de MayB / The flow of dance, emotions and thoughts : a contribution to a sociology of emotions : looking at Giselle and MayB

Fournié, Fanny 12 December 2012 (has links)
Ce travail propose une réflexion menée à la croisée d'une sociologie des émotions, objet principal de la recherche, et d'une sociologie de l'art. En effet, la représentation d'un ballet romantique, Giselle, de Jules Perrot et Jean Coralli et d'un ballet contemporain, MayB, de Maguy Marin, forme le terrain de l'enquête. L'enjeu de l'analyse a consisté à rendre visibles les différents mouvements des émotions, à l'œuvre lors d'une soirée chorégraphique. D'un côté, le mouvement des danseurs sur la scène, qui, s'appuyant sur la technique corporelle, mais aussi la musique, le récit, les costumes et les décors, confectionnent les émotions. D'un autre côté, le mouvement des pensées, visibles chez les danseurs comme chez les spectateurs, à travers une sorte de dialogue intérieur participant à la fabrication des émotions individuelles. Enfin, le mouvement collectif des émotions échangées entre les danseurs et les spectateurs, dans un va-et-vient permanent, nécessaire à la construction de la matière chorégraphique. La méthodologie, qualitative, a été constituée de manière à saisir les différents temps de cette confection émotionnelle. Les observations directes, réalisées durant les répétitions, permettent de saisir, en amont, comment une technique de danse fabrique les émotions. L'observation participante lors des spectacles offre l'illustration, intime, du vécu corporel et émotionnel d'un spectateur : le ballet devient expérience, les spectateurs, acteurs de la soirée en train de se faire. Enfin, les entretiens, réalisés auprès des danseurs et des spectateurs, fournissent une matière sensible à la réflexion, tournée vers une sociologie compréhensive. Au final, la thèse présente les émotions comme « le corps » des relations sociales. Au travers elles, les individus se saisissent les uns des autres, soulignent leurs différences ou leurs similitudes, s'adaptent ou non au groupe, selon la « prise » ou la « déprise » des émotions du ballet sur eux. / This study stands at a crossroads between a sociology of emotions – the main focus of our research – and a sociology of art. The survey here presented is grounded in two dance performances, the romantic ballet Giselle, by Jules Perrot and Jean Coralli on the one hand, and on the other hand, the contemporary dance performance MayB, by Maguy Marin The point of this analysis was to bring out the various movements of emotion at play in the course of a choreographic performance. First, I have studied the dancers' movements on stage, which, while resting on the body's technique as well as the music, the story, the costumes and the decors, participate in the making of emotions. Second, I have delved into the movement of thoughts, perceptible in the dancers and in the audience, via a kind of interior dialogue which takes part in the making of various emotions. Last but not least, I have looked into the collective and continuous flow of emotions moving back and forth between the dancers and the audience, and which is necessary for the construction of choreographic material. The methodology here used is a qualitative one, aiming to grasp the various moments in the making of emotions. Direct observations carried out during rehearsals allow for a prior understanding of how a dance technique can create emotions. Participatory observation during the performances grants an intimate illustration of the physical and emotional response of a spectator: the ballet becomes experience and the spectators become actors of the evening in the making. Finally, the audience and dancers' interviews offer food for thought, building towards a comprehensive sociology. In the end, this thesis presents emotions as “the body” of social relationships. Through them, individuals take hold of one another, underlining their differences or similarities. They adapt to the group or they do not, depending on the hold the emotions of the ballet may have on them.

Expanding Mediation Theory : Gang Conflict and Mediation in El Salvador

Van Gestel, Gregory January 2018 (has links)
The field of mediation within peace and conflict studies has remained almost entirely focused on state-based armed conflicts and traditional non-state armed groups (NSAG). This restricts our ability to address other actors and emerging forms of conflict in non-conflict and post-conflict settings. This includes a certain classification of gangs who display strong similarities to typical NSAGs. This study analyses gang mediation and its effects on levels of violence in gang conflicts in El Salvador through the lens of traditional mediation theory from the field of peace and conflict studies. It seeks to answer the question, how does mediation influence levels of violence within gang conflicts? More specifically, addressing the hypotheses that, mediation between gangs, and government support for mediation, will likely lead to lower levels of violence. Using a qualitative comparative case study method, employing a structured, focused comparison between three different time periods in El Salvador, I find support for both hypotheses, showing that gang mediation leads to a significant reduction in violence albeit conditional on government support. In addition, factors such as dialogue, information sharing, leverage, concessions and the signing of an agreement are essential in the process between mediation and lower levels of violence.
