1	Effects of an Intimate Partner Violence Intervention on Relationship Behaviors with Tests of Moderators: A Multilevel Analysis Franchot, Katie 08 August 2017 (has links) Annually, nearly 7 million women and 5.5 million men experience some form of intimate partner violence, which has serious health impacts. IPV has also been shown to limit the impact of early childhood home visiting interventions. Given the positive impacts of home visiting, reducing IPV in that setting could alleviate the negative impacts of IPV and improve mother and child outcomes as well. The analysis performed are from data from a randomized trial of an intimate partner violence intervention that was embedded into the Nurse Family Partnership, an evidence-based home visiting program. The intervention focused on identifying IPV, and for women without severe IPV, improving relationship skills including communication patterns and conflict resolution. The goal of this analysis is to examine how changes in partner and history of IPV moderate the relationship skills outcomes. This study aims to fill the gap in knowledge regarding the relationship between a home visiting intervention and relationship skill outcomes in women enrolled in the home visiting program, the Nurse Family Partnership. The purpose of the study is to discover whether the relationship skills differ in participants with stable vs. unstable partnerships and with those who experienced IPV before the start of the study. Women were randomized to NFP as usual (n=105) or NFP+, which included NFP plus the IPV intervention (n=133). Participants were surveyed at baseline, and at one and two-year follow-up with 81% retention over 2 years. Standardized assessment tools assessed relationship quality, communication, problem solving, partner support, relationship decision making, and psychological maltreatment. Marginal modeling was conducted to examine whether the intervention accounted for any change in relationship variables and whether the impact is moderated by history of IPV and changes in partnership. Multilevel modeling of the outcome variables showed some main effects of time such that conflict resolution improves for the intervention group (p<0.05). There is one clinically significant three-way interaction showing reduced relationship danger in the intervention for women with a history of IPV (p<0.06). There were no significant interactions for the partnership change moderator. Multilevel Modeling Intimate Partner Violence Marginal Model Moderator Relationship Skills
2	Likelihood-Based Approach for Analysis of Longitudinal Nominal Data Using Marginalized Random Effects Models Lee, Keunbaik, Kang, Sanggil, Liu, Xuefeng, Seo, Daekwan 01 August 2011 (has links) Likelihood-based marginalized models using random effects have become popular for analyzing longitudinal categorical data. These models permit direct interpretation of marginal mean parameters and characterize the serial dependence of longitudinal outcomes using random effects [12,22]. In this paper, we propose model that expands the use of previous models to accommodate longitudinal nominal data. Random effects using a new covariance matrix with a Kronecker product composition are used to explain serial and categorical dependence. The Quasi-Newton algorithm is developed for estimation. These proposed methods are illustrated with a real data set and compared with other standard methods. Kronecker product likelihood-based model marginal model quasi-newton random effects

V první části práce se zabýváme možným rozšířením Coxova modelu proporcionálního rizika, který se využívá při analýze cenzoro- vaných dat, pro analýzu výskytu opakovaných událostí. Hlavní část práce je věnována odhadu parametr· v marginálních modelech a jejich asymptotickým vlastnostem. Následně se zabýváme i odhadem parametr· v marginálních mo- delech pro mnohorozměrná cenzorovaná data. Vhodnost použití marginálních model· je zkoumána pomocí simulací. 1

Kersuzan, Claire 11 December 2012 (has links) Ce travail se propose d’examiner les conséquences du décès parental précoce sur la trajectoire biographique des enfants, dans un régime de mortalité où la principale perturbation n’est pas le VIH/SIDA, mais une grave crise socio-politique. Le Burundi est l’un des épicentres du conflit traversé dans les années 90 par la région des Grands Lacs. A l’aide des données de l’Enquête Socio-Démographique et de Santé de la Reproduction (ESDSR) menée au Burundi en 2002, nous analysons l’impact du décès parental précoce sur un grand nombre de dimensions du parcours de vie des enfants burundais: mortalité, violence et exploitation sexuelle, séparation des membres de la fratrie, scolarité, entrée précoce dans le travail, ressources, conditions de l’héritage, entrée dans la vie reproductive et familiale. Ces analyses sont menées selon l’âge de l’enfant au moment du décès d’au moins un de ses parents, tout en cherchant à évaluer l’effet de la cause de décès des parents (crise/autre cause) sur les résultats obtenus. On montre que la perturbation du parcours de vie des enfants ayant précocement vécu le décès de leur père est mineure. A l’inverse l’expérience précoce de la mère ou du dernier parent survivant affecte la plupart des dimensions de la trajectoire biographique des enfants. La crise burundaise amplifie et, dans certains cas, transforme voire renverse la relation entre l’expérience précoce du décès d’au moins un parent et la trajectoire des enfants. L’orphelin à cause des massacres de masse de 1993 est un orphelin « politique » dont la protection et le soutien par les instances politiques, militaires, administratives et humanitaires est devenu un enjeu de la crise elle-même. / The aim of this paper is to analyze lifetime effects of parental death during childhood, in a country context where HIV/AIDS isn’t the main cause of death among young adults but deaths caused by a major socio-political crisis. During the 90’s, Burundi hosted the cradle of the regional conflict in the Great Lakes. A 2002 demographic, social and reproductive health survey in Burundi (ESDSR) will provide us the information required to analyze impact of early parental death, on a complex panel of life perspectives for children: mortality, violence and sexual abuse, separation of siblings, schooling, working at early age, resources, heritage, early marriage and age at first birth. These analyses are led by child age at early parental death, along with an attempt to estimate the effect from the cause of this death (crisis or other) on results. The strength of leading conclusions is consolidated by the mean of exchanging results, these results being derived from several analysis methods: bivariate and multivariate logistic models adapted or not to clustered data (standard, multilevel, marginal and fixed-effects logistic regressions).We bring lights on the minor effect of early father loss on child life trajectory. On the contrary, early mother or last living parent death experience affects almost every child life trajectory. Burundi crisis emphases but in some cases, reverses those effects from negative to positive. 1993 mass slaughters orphans are “political” orphans. Their political, military, administrative and humanitarian protections became part of the main goals, in the crisis itself.
