Texto completo da fonteResumo:
Population control programs such as family planning and the introduction of sex identification technologies has helped to create skewed sex ratios in northern India and particularly in the state of Haryana. Due to a surplus of men and the numbers of missing females, an organized business of bride trafficking has emerged where poor women from eastern and northeastern states of India are bought and brought to Haryana for the purpose of marriage. This thesis explores how skewed sex ratios have contributed to the phenomenon of bride trafficking in Haryana guided by the theoretical framework of violences of development which argues that there is a hidden paradox within development. This was done by conducting a conventional content analysis in order to create a deeper understanding of the phenomenon. There is scarce research on bride trafficking, therefore this study contributes with extended knowledge in order to shed a light on the increasing trade with females.

Texto completo da fonteResumo:
Les réseaux sociaux sont devenus des outils de communication primordiaux et sont utilisés quotidiennement par des centaines de millions d’utilisateurs. Tous ces utilisateurs n’ont pas le même comportement sur ces réseaux. Si certains ont une faible activité, publient rarement des messages et suivent peu d’utilisateurs, d’autres, à l’opposé, ont une activité importante, avec de nombreux abonnés et très publient régulièrement. Le rôle important de ces utilisateurs influents en font des cibles intéressantes pour de nombreuses applications, par exemple pour la surveillance ou la publicité. Après une étude des méta-donées de ces utilisateurs, afin de d´détecter des comptes anormaux, nous présentons une approche permettant de d´détecter des utilisateurs devenant populaires. Notre approche s’appuie sur une modélisation de l’évolution de la popularité sous la forme de motifs fréquents. Ces motifs décrivent les comportements de gain en popularité. Nous proposons un modèle de matching des motifs permettant d’être utilisé avec un flux de données et, nous montrons sa capacité à passer à l’échelle en le comparant à des modèles classiques. Enfin, nous présentons une approche de clustering basé sur le PageRank. Ces travaux permettent d’identifier des groupes d’utilisateurs partageant le même rolex, en utilisant les graphes ’interactions qu’ils génèrentSocial networks (SN) are omnipresent in our lives today. Not all users have the same behavior on these networks. If some have a low activity, rarely posting messages and following few users, some others at the other extreme have a significant activity, with many followers and regularly posts. The important role of these popular SN users makes them the target of many applications for example for content monitoring or advertising. After a study of the metadata of these users, in order to detect abnormal accounts, we present an approach allowing to detect users who are becoming popular. Our approach is based on modeling the evolution of popularity in the form of frequent patterns. These patterns describe the behaviors of gaining popularity. We propose a pattern matching model which can be used with a data stream and we show its scalability and its performance by comparing it to classic models. Finally, we present a clustering approach based on PageRank. This work allow to identify groups of users sharing the same role, using the interaction graphs

But driving discrete antennas separated by several wavelengths around the missile body with a single transmitter can result in an antenna pattern with deep nulls in the roll plane. Varying the relative signal phase or amplitude among the signals driving the antennas as well as the polarization of the antennas can be used to change the nulls in an attempt to decrease the null depth. In this paper the effects of phase, amplitude, and polarization on the roll-plane pattern are examined and measurement data presented.

Josefsson, Maria. "Attrition in Studies of Cognitive Aging". Doctoral thesis, Umeå universitet, Statistik, 2013. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-82514.
Texto completo da fonteResumo:
Longitudinal studies of cognition are preferred to cross-sectional stud- ies, since they offer a direct assessment of age-related cognitive change (within-person change). Statistical methods for analyzing age-related change are widely available. There are, however, a number of challenges accompanying such analyzes, including cohort differences, ceiling- and floor effects, and attrition. These difficulties challenge the analyst and puts stringent requirements on the statistical method being used. The objective of Paper I is to develop a classifying method to study discrepancies in age-related cognitive change. The method needs to take into account the complex issues accompanying studies of cognitive aging, and specifically work out issues related to attrition. In a second step, we aim to identify predictors explaining stability or decline in cognitive performance in relation to demographic, life-style, health-related, and genetic factors. In the second paper, which is a continuation of Paper I, we investigate brain characteristics, structural and functional, that differ between suc- cessful aging elderly and elderly with an average cognitive performance over 15-20 years. In Paper III we develop a Bayesian model to estimate the causal effect of living arrangement (living alone versus living with someone) on cog- nitive decline. The model must balance confounding variables between the two living arrangement groups as well as account for non-ignorable attrition. This is achieved by combining propensity score matching with a pattern mixture model for longitudinal data. In paper IV, the objective is to adapt and implement available impu- tation methods to longitudinal fMRI data, where some subjects are lost to follow-up. We apply these missing data methods to a real dataset, and evaluate these methods in a simulation study.

Texto completo da fonteResumo:
In cluster randomized trials (CRTs), groups of participants are randomized as opposed to individual participants. This design is often chosen to minimize treatment arm contamination or to enhance compliance among participants. In CRTs, we cannot assume independence among individuals within the same cluster because of their similarity, which leads to decreased statistical power compared to individually randomized trials. The intracluster correlation coefficient (ICC) is crucial in the design and analysis of CRTs, and measures the proportion of total variance due to clustering. Missing data is a common problem in CRTs and should be accommodated with appropriate statistical techniques because they can compromise the advantages created by randomization and are a potential source of bias. In three papers, I investigate statistical approaches for handling missing data in CRTs. In the first paper, I carry out a systematic review evaluating current practice of handling missing data in CRTs. The results show high rates of missing data in the majority of CRTs, yet handling of missing data remains suboptimal. Fourteen (16%) of the 86 reviewed trials reported carrying out a sensitivity analysis for missing data. Despite suggestions to weaken the missing data assumption from the primary analysis, only five of the trials weakened the assumption. None of the trials reported using missing not at random (MNAR) models. Due to the low proportion of CRTs reporting an appropriate sensitivity analysis for missing data, the second paper aims to facilitate performing a sensitivity analysis for missing data in CRTs by extending the pattern mixture approach for missing clustered data under the MNAR assumption. I implement multilevel multiple imputation (MI) in order to account for the hierarchical structure found in CRTs, and multiply imputed values by a sensitivity parameter, k, to examine parameters of interest under different missing data assumptions. The simulation results show that estimates of parameters of interest in CRTs can vary widely under different missing data assumptions. A high proportion of missing data can occur among CRTs because missing data can be found at the individual level as well as the cluster level. In the third paper, I use a simulation study to compare missing data strategies to handle missing cluster level covariates, including the linear mixed effects model, single imputation, single level MI ignoring clustering, MI incorporating clusters as fixed effects, and MI at the cluster level using aggregated data. The results show that when the ICC is small (ICC ≤ 0.1) and the proportion of missing data is low (≤ 25\%), the mixed model generates unbiased estimates of regression coefficients and ICC. When the ICC is higher (ICC > 0.1), MI at the cluster level using aggregated data performs well for missing cluster level covariates, though caution should be taken if the percentage of missing data is high.

Texto completo da fonteResumo:
Australian evangelical local churches participate in mission in a variety of ways with varying levels of emphasis on local and distant mission activities. This research employs a mixed method grounded theory approach to explore and understand the factors shaping these patterns of mission involvement. A closed-question survey was completed by leaders of 205 evangelical churches in New South Wales and the Australian Capital Territory. Responses revealed substantial diversity of practice and indicated a relationship between local and distant mission activities suggesting that a church’s involvement in distant mission may stimulate involvement in local mission, but not vice versa. Semi-structured interviews were performed with members from ten churches surveyed which displayed high levels of involvement in local mission and either high or low levels of involvement in distant mission. Analysis of these interviews revealed widespread similarities in ecclesiological and missiological convictions, yet notable differences in organisational culture and climate between more and less globally engaged churches. The most substantial difference between these groups of churches was the presence relational networks with distant mission workers in highly engaged churches. Viewed from the perspectives of social exchange and social capital theory, these relational networks stimulate church member involvement in both local and distant mission and thereby influence the culture and climate of mission involvement. Churches displaying high levels of engagement in local and distant mission had a ‘unified participatory missiology’ which shaped church culture such that all members were personally engaged. By contrast, the churches with low levels of distant mission engagement were said to have a ‘local-focused bifurcated missiology’ with a delegatory approach to distant mission.

Daniel, William Harrison. "Patterns in mission preaching : the representation of the Christian message and Efik response in the Scottish Calabar Mission, Nigeria, 1846-1900". Thesis, University of Edinburgh, 1993. http://hdl.handle.net/1842/27861.
Texto completo da fonteResumo:
The principal objective of this thesis is to examine the interaction, during the period from 1846-1900, between the Christian preaching of the United Presbyterian Church of Scotland and the local response of the Efik people in the Cross River basin of present day South-Eastern Nigeria. The historical development of mission preaching in Calabar, as well as its theological background is established. The interpretation of the mission's proclamation by the Efik people in terms of their local religion and culture is treated. The history of Christian proclamation and local response in the region is explored through the following categories of cultural interaction: the representation, rejection, reception, and reformulation of the mission message. The work is an attempt to get beyond crude stereotypes in academic literature of mission preaching as merely a destroyer of indigenous culture. The thesis contends that mission preaching and local response were more diverse than previous scholarly work suggests and that the sources for this study demonstrate how the Efik people were active agents in the transmission of Christianity within the region, rather than passive recipients. It argues that the nature of the mission's evangelism cannot be properly understood without an appropriate recognition of the local religious and cultural categories used by the Efik people to reject, receive, reformulate, and 're-present' the biblical message to others in the area. Conversely, we maintain that to assess properly the contribution of the Efik people in the interpretation and transmission of emerging Efik Christianity, it is necessary to establish the form, the content, and the extent of mission preaching.

Ollerton, David R. J. "Mission in a Welsh context : patterns of Nonconformist mission in Wales and the challenge of contextualisation in the twenty first century". Thesis, University of Chester, 2015. http://hdl.handle.net/10034/611381.
Texto completo da fonteResumo:
This thesis considers aspects of contextualisation in the mission of local churches in twenty-first century Wales. Welsh Nonconformity rose rapidly to a dominant position in Welsh society and culture in the nineteenth century, but has subsequently declined equally rapidly. By the beginning of the twenty-first century its total demise is predicted. The research examines the contextual factors in this decline, and their relevance for possible recovery. Contextualisation is an essential part of missiology, in calibrating appropriate mission to the distinctives of a particular nation or locality. Wales is shown to be a distinctive context for mission, both nationally and regionally, in relation to specific aspects: religious, geographic, ethnic, linguistic, cultural, social and political. Contextual studies have been done for other mission contexts, but not for Wales. This research seeks to address this lack. The thesis first outlines the development of the main approaches in global mission, their underlying assumptions, and their outworking in the mission of local churches in the West. The approaches have been identified as Evangelistic, Lausanne, Missio Dei, Liberal and Emergent. Drawing on hundreds of questionnaire responses and extensive interviews with Nonconformist leaders, the research examines how the different approaches to mission have been expressed in Wales, and how each approach adjusted to each aspect of context. The growth trends of the different approaches, patterns of church and mission, and adjustments to Welsh contexts in the first decade of the twenty-first century, or not, are then examined. The resulting analysis enables good practice to be identified, and approaches for effective mission suggested for the coming decades.

Texto completo da fonteResumo:
Saab Aerosystems, a part of Saab AB, has the overall responsibility for the development of the fourth generation fighter aircraft JAS 39 Gripen. When planning a mission for one or more aircrafts, a computer program called Mission Support System is used. Some of the data from the planning is then transferred to the actual aircraft. Today there are some unwanted restrictions in the planning software. One of these restrictions is about the fact that a number of parameters that controls the output from a planned mission are not configurable runtime, i.e. a reinstallation at customers location is needed to change this. The main purpose of this thesis was to propose a new design and a new framework that solves the inflexibility described above. The design should also be validated by a test implementation. A number of different designs were proposed and four of these were selected to be candidates for being implemented. An important tool used when developing the designs was the theory of design patterns. To choose one of the four a ranking system, based on both measurable metrics and non-measurable experience, was used. One design was selected to be the best and after implementing of the design it was considered to be valid. Future work can consist of rewriting all modules in the software to use the new framework.

Texto completo da fonteResumo:
Missile Detection System (MDS) is one of the main components of a self-protection system developed against the threat of guided missiles for airborne platforms. The requirements such as time critical operation and high accuracy in classification performance make the &lsquoPattern Recognition&rsquo
problem of an MDS a hard task. Problem can be defined in two main parts such as &lsquo
Feature Set Evaluation&rsquo
(FSE) and &lsquo
Classifier&rsquo
designs. The main goal of feature set evaluation is to employ a dimensionality reduction process for the input data set, while not disturbing the classification performance in the result. In this thesis study, FSE approaches are investigated for the pattern recognition problem of a generic MDS. First, synthetic data generation is carried out in software environment by employing generic models and assumptions in order to reflect the nature of a realistic problem environment. Then, data sets are evaluated in order to draw a baseline for further feature set evaluation approaches. Further, a theoretical background including the concepts of Class Separability, Feature Selection and Feature Extraction is given. Several widely used methods are assessed in terms of convenience for the problem by giving necessary justifications depending on the data set characteristics. Upon this background, software implementations are performed regarding several feature set evaluation techniques. Simulations are carried out in order to process dimensionality reduction. For the evaluation of the resulting data sets in terms of classification performance, software implementation of a classifier is realized. Resulting classification performances of the applied approaches are compared and evaluated.

Texto completo da fonteResumo:
By 1836 both the Presbyterians and the Jesuits had penetrated the Pacific Northwest. The Whitmans and the Spaldings were the first Presbyterians to settle in this region. The Whitmans settled with the Cayuse at W ailaptu near Walla Walla and the Spaldings resided at Lapwaii with the Nez Perce tribe. Although two Canadian priests were working in this region, it was not until 1840, with the arrival of Father Jean-Pierre DeSmet that the Jesuits commenced their missionary work. Fr. DeSmet initially settled with the Flathead tribe in the Bitterroot Valley of Montana. This paper observes how the Jesuits in Montana and the Presbyterians in the Columbia basin related with their respective tribes. With each situation a pattern occurs of tribal acceptance and rejection. The different tribes were initially eager to learn from the missionaries but as the years pass by, the novelty of Christianity wore thin. What became more obvious to the tribal members was that slowly their numbers were diminishing due to disease brought over by white settlers and simultaneously their land was disappearing as the pioneers built their homes. This observation resulted directly in the Native American rejection of the Christian missionaries. The Jesuits and the Spaldings were fortunate to escape without physical harm. This was not the case, though for Dr. Marcus and Narcissa Whitman who lost their lives in the Whitman massacre. To understand the reasons for this rejection, this paper spends the first few chapters looking into the background of the three tribes as well as the missionaries. It then examines the three different tribes and their history with their respective missionaries, observing the reasons, both long and short term for their failures. In the final chapter the paper investigates the obvious yet undocumented competition between the Catholic and Protestant missionaries to be the sole religion in this region. Their co-existence of these two faiths was another factor which resulted in the disillusionment of the Native American tribes in this region.

Moreno, Betancur Margarita. "Regression modeling with missing outcomes : competing risks and longitudinal data". Thesis, Paris 11, 2013. http://www.theses.fr/2013PA11T076/document.
Texto completo da fonteResumo:
Les données manquantes sont fréquentes dans les études médicales. Dans les modèles de régression, les réponses manquantes limitent notre capacité à faire des inférences sur les effets des covariables décrivant la distribution de la totalité des réponses prévues sur laquelle porte l'intérêt médical. Outre la perte de précision, toute inférence statistique requière qu'une hypothèse sur le mécanisme de manquement soit vérifiée. Rubin (1976, Biometrika, 63:581-592) a appelé le mécanisme de manquement MAR (pour les sigles en anglais de « manquant au hasard ») si la probabilité qu'une réponse soit manquante ne dépend pas des réponses manquantes conditionnellement aux données observées, et MNAR (pour les sigles en anglais de « manquant non au hasard ») autrement. Cette distinction a des implications importantes pour la modélisation, mais en général il n'est pas possible de déterminer si le mécanisme de manquement est MAR ou MNAR à partir des données disponibles. Par conséquent, il est indispensable d'effectuer des analyses de sensibilité pour évaluer la robustesse des inférences aux hypothèses de manquement.Pour les données multivariées incomplètes, c'est-à-dire, lorsque l'intérêt porte sur un vecteur de réponses dont certaines composantes peuvent être manquantes, plusieurs méthodes de modélisation sous l'hypothèse MAR et, dans une moindre mesure, sous l'hypothèse MNAR ont été proposées. En revanche, le développement de méthodes pour effectuer des analyses de sensibilité est un domaine actif de recherche. Le premier objectif de cette thèse était de développer une méthode d'analyse de sensibilité pour les données longitudinales continues avec des sorties d'étude, c'est-à-dire, pour les réponses continues, ordonnées dans le temps, qui sont complètement observées pour chaque individu jusqu'à la fin de l'étude ou jusqu'à ce qu'il sorte définitivement de l'étude. Dans l'approche proposée, on évalue les inférences obtenues à partir d'une famille de modèles MNAR dits « de mélange de profils », indexés par un paramètre qui quantifie le départ par rapport à l'hypothèse MAR. La méthode a été motivée par un essai clinique étudiant un traitement pour le trouble du maintien du sommeil, durant lequel 22% des individus sont sortis de l'étude avant la fin.Le second objectif était de développer des méthodes pour la modélisation de risques concurrents avec des causes d'évènement manquantes en s'appuyant sur la théorie existante pour les données multivariées incomplètes. Les risques concurrents apparaissent comme une extension du modèle standard de l'analyse de survie où l'on distingue le type d'évènement ou la cause l'ayant entrainé. Les méthodes pour modéliser le risque cause-spécifique et la fonction d'incidence cumulée supposent en général que la cause d'évènement est connue pour tous les individus, ce qui n'est pas toujours le cas. Certains auteurs ont proposé des méthodes de régression gérant les causes manquantes sous l'hypothèse MAR, notamment pour la modélisation semi-paramétrique du risque. Mais d'autres modèles n'ont pas été considérés, de même que la modélisation sous MNAR et les analyses de sensibilité. Nous proposons des estimateurs pondérés et une approche par imputation multiple pour la modélisation semi-paramétrique de l'incidence cumulée sous l'hypothèse MAR. En outre, nous étudions une approche par maximum de vraisemblance pour la modélisation paramétrique du risque et de l'incidence sous MAR. Enfin, nous considérons des modèles de mélange de profils dans le contexte des analyses de sensibilité. Un essai clinique étudiant un traitement pour le cancer du sein de stade II avec 23% des causes de décès manquantes sert à illustrer les méthodes proposéesMissing data are a common occurrence in medical studies. In regression modeling, missing outcomes limit our capability to draw inferences about the covariate effects of medical interest, which are those describing the distribution of the entire set of planned outcomes. In addition to losing precision, the validity of any method used to draw inferences from the observed data will require that some assumption about the mechanism leading to missing outcomes holds. Rubin (1976, Biometrika, 63:581-592) called the missingness mechanism MAR (for “missing at random”) if the probability of an outcome being missing does not depend on missing outcomes when conditioning on the observed data, and MNAR (for “missing not at random”) otherwise. This distinction has important implications regarding the modeling requirements to draw valid inferences from the available data, but generally it is not possible to assess from these data whether the missingness mechanism is MAR or MNAR. Hence, sensitivity analyses should be routinely performed to assess the robustness of inferences to assumptions about the missingness mechanism. In the field of incomplete multivariate data, in which the outcomes are gathered in a vector for which some components may be missing, MAR methods are widely available and increasingly used, and several MNAR modeling strategies have also been proposed. On the other hand, although some sensitivity analysis methodology has been developed, this is still an active area of research. The first aim of this dissertation was to develop a sensitivity analysis approach for continuous longitudinal data with drop-outs, that is, continuous outcomes that are ordered in time and completely observed for each individual up to a certain time-point, at which the individual drops-out so that all the subsequent outcomes are missing. The proposed approach consists in assessing the inferences obtained across a family of MNAR pattern-mixture models indexed by a so-called sensitivity parameter that quantifies the departure from MAR. The approach was prompted by a randomized clinical trial investigating the benefits of a treatment for sleep-maintenance insomnia, from which 22% of the individuals had dropped-out before the study end. The second aim was to build on the existing theory for incomplete multivariate data to develop methods for competing risks data with missing causes of failure. The competing risks model is an extension of the standard survival analysis model in which failures from different causes are distinguished. Strategies for modeling competing risks functionals, such as the cause-specific hazards (CSH) and the cumulative incidence function (CIF), generally assume that the cause of failure is known for all patients, but this is not always the case. Some methods for regression with missing causes under the MAR assumption have already been proposed, especially for semi-parametric modeling of the CSH. But other useful models have received little attention, and MNAR modeling and sensitivity analysis approaches have never been considered in this setting. We propose a general framework for semi-parametric regression modeling of the CIF under MAR using inverse probability weighting and multiple imputation ideas. Also under MAR, we propose a direct likelihood approach for parametric regression modeling of the CSH and the CIF. Furthermore, we consider MNAR pattern-mixture models in the context of sensitivity analyses. In the competing risks literature, a starting point for methodological developments for handling missing causes was a stage II breast cancer randomized clinical trial in which 23% of the deceased women had missing cause of death. We use these data to illustrate the practical value of the proposed approaches

Texto completo da fonteResumo:
Over a six-year period, this study compares the demonstrated priorities and efficiency of 328 U.S. community colleges to the historical mission of community colleges which includes the goals of unrestricted student access, service to many students, and the delivery of comprehensive, high-quality, low-cost educational programs. Sample data was provided by NACUBO for 328 institutions (out of a U.S. population of 770) reporting in both 1981-82 and 1986-87. The study compares the 1986-87 resource allocation patterns for each institution to the 1981-82 patterns for that same institution. Measurements include the level, mix, and rate of change in F.T.E. student enrollments, square footage, market penetration, the number of full-time faculty, F.T.E. faculty, support staff, and expenditures for Direct Instruction, Instructional Support, Student Services, Institutional Support, and Plant Operations. 2 Summary data is presented for the sample as a whole and separately by state for institutions with enrollment growth and for institutions wi th enrollment decline. Over the six-year period, sample institutions received $1.4 billion in incremental revenues. Classroom teaching received 43.1 cents of every incremental dollar, ranked fourth out of five expenditure categories in rate of expenditure growth and fell from 50.5% of total expenditures to 48.4%. Square footage and F.T.E. support staff increased 9.3% and 13.2% respectively while F.T.E. student enrollments and the number of full-time faculty declined 2.9% and 2.4% respectively. By 1986-87 fewer F.T.E. students and a smaller percentage of service area populations were served by fewer full-time teachers, at higher cost by substantially more square footage and support staff. The study concludes that these patterns are inefficient and inconsistent with the historical mission of community colleges.

Heward, Maclane Elon. "The First Mission of the Twelve Apostles: 1835". BYU ScholarsArchive, 2013. https://scholarsarchive.byu.edu/etd/3478.
Texto completo da fonteResumo:
The Quorum of the Twelve Apostles for the Church of Jesus Christ of Latter-day Saints is an administrative and ecclesiastical quorum. The Church, first organized in 1830, did not organize the Quorum of Twelve Apostles until 1835. When it was organized, Joseph Smith outlined the quorum's responsibilities through revelation. The Twelve were assigned two unique and specific responsibilities: to take the gospel to the nations of the earth and to form a traveling high council for the regulating of the Church outside of its stakes. The first opportunity for the Twelve to fulfill their responsibilities was in May 1835 when they were assigned to travel to the eastern United States and southern Canada. There they both preached the gospel and regulated the branches of the Church. This mission represents not only the first time the Apostles fulfilled their assigned responsibilities but the only time that they filled their responsibilities as an entire quorum. It is surprising that more secondary literature on this mission is not available. This thesis seeks to commence an academic conversation regarding this mission and its impact both on the quorum's development and on the Church in its outlying areas. Chapter 1 details the preparation of the individual members of the Twelve to fulfill this mission. It discusses the preparation of the Twelve prior to their call to the apostleship. It also discusses the training that took place between their call and the commencement of this mission. As an administrative body for the membership of the Church, the Twelve spent the majority of their time on this mission with the members of the Church. Chapter 2 identifies the unique purpose of the Twelve on this mission and how that purpose was fulfilled. Joseph Smith originally laid out the geographic framework for this mission, which sent the Twelve into Canada and throughout much of the northeastern United States. Chapter 3 identifies the locations of the Twelve based on available records and seeks to provide an answer to how the Twelve decided which areas to preach in. Many individuals were baptized during this five-month mission. Chapter 4 identifies what the Twelve taught and the sources that they used. It also discusses the reaction of the people they taught. The concluding chapter summarizes the thesis and identifies areas for further research.

This research augments current Multiple Objective Evolutionary Algorithms with methods that dramatically reduce the time required to evolve toward a region of interest in objective space.
Multiple Objective Evolutionary Algorithms (MOEAs) are superior to other optimization techniques when the search space is of high dimension and contains many local minima and maxima. Likewise, MOEAs are most interesting when applied to non-intuitive
complex systems. But, these systems are often computationally expensive to calculate. When these systems require independent computations to evaluate each objective, the computational expense grows with each additional objective. This method has developed methods that reduces the time required for evolution by reducing the number of objective evaluations, while still evolving solutions that are Pareto optimal. To date, all other Multiple Objective Evolutionary Algorithms (MOEAs) require the evaluation of all objectives before a fitness value can be assigned to an individual.
The original contributions of this thesis are:
1. Development of a hierarchical search space description that allows association of crossover and mutation settings with elements of the genotypic description.
2. Development of a method for parallel evaluation of individuals that removes the need for delays for synchronization.
3. Dynamical evolution of thresholds for objectives to allow partial evaluation of objectives for individuals.
4. Dynamic objective orderings to minimize the time required for unnecessary objective evaluations.
5. Application of MOEAs to the computationally
expensive flare pattern design domain.
6. Application of MOEAs to the optimization of fielded missile warning receiver algorithms.
7. Development of a new method of using MOEAs for
automatic design of pattern recognition systems.

Texto completo da fonteResumo:
Ce mémoire présente les travaux réalisés dans le cadre de ma thèse. Celle-ci a été menée dans le groupe ISPR (ImageS, Perception systems and Robotics) de l'Institut Pascal au sein de l'équipe ComSee (Computers that See). Ces travaux s'inscrivent dans le cadre du projet Bio Rafale initié par la société clermontoise Vesalis et financé par OSEO. Son but est d'améliorer la sécurité dans les stades en s'appuyant sur l'identification des interdits de stade. Les applications des travaux de cette thèse concernent la détection de visages. Elle représente la première étape de la chaîne de traitement du projet. Les détecteurs les plus performants utilisent une cascade de classifieurs boostés. La notion de cascade fait référence à une succession séquentielle de plusieurs classifieurs. Le boosting, quant à lui, représente un ensemble d'algorithmes d'apprentissage automatique qui combinent linéairement plusieurs classifieurs faibles. Le détecteur retenu pour cette thèse utilise également une cascade de classifieurs boostés. L'apprentissage d'une telle cascade nécessite une base d'apprentissage ainsi qu'un descripteur d'images. Cette description des images est ici assurée par des matrices de covariance. La phase d'apprentissage d'un détecteur d'objets détermine ces conditions d'utilisation. Une de nos contributions est d'adapter un détecteur à des conditions d'utilisation non prévues par l'apprentissage. Les adaptations visées aboutissent à un problème de classification avec données manquantes. Une formulation probabiliste de la structure en cascade est alors utilisée pour incorporer les incertitudes introduites par ces données manquantes. Cette formulation nécessite l'estimation de probabilités a posteriori ainsi que le calcul de nouveaux seuils à chaque niveau de la cascade modifiée. Pour ces deux problèmes, plusieurs solutions sont proposées et de nombreux tests sont effectués pour déterminer la meilleure configuration. Enfin, les applications suivantes sont présentées : détection de visages tournés ou occultés à partir d'un détecteur de visages de face. L'adaptation du détecteur aux visages tournés nécessite l'utilisation d'un modèle géométrique 3D pour ajuster les positions des sous-fenêtres associées aux classifieurs faibles.

Nesta tese apresentam-se desenvolvimentos metodológicos para analisar dados com omissão e também estudos delineados para compreender os resultados de tais análises. Escrutinam-se análises de sensibilidade bayesiana e clássica para dados com respostas categorizadas sujeitas a omissão. Mostra-se que as componentes subjetivas de cada abordagem podem influenciar os resultados de maneira não-trivial, independentemente do tamanho da amostra, e que, portanto, as conclusões devem ser cuidadosamente avaliadas. Especificamente, demonstra-se que distribuições \\apriori\\ comumente consideradas como não-informativas ou levemente informativas podem, na verdade, ser bastante informativas para parâmetros inidentificáveis, e que a escolha do modelo sobreparametrizado também tem um papel importante. Quando há omissão em variáveis explicativas, também é necessário propor um modelo marginal para as covariáveis mesmo se houver interesse apenas no modelo condicional. A especificação incorreta do modelo para as covariáveis ou do modelo para o mecanismo de omissão leva a inferências enviesadas para o modelo de interesse. Trabalhos anteriormente publicados têm-se dividido em duas vertentes: ou utilizam distribuições semiparamétricas/não-paramétricas, flexíveis para as covariáveis, e identificam o modelo com a suposição de um mecanismo de omissão não-informativa, ou empregam distribuições paramétricas para as covariáveis e permitem um mecanismo mais geral, de omissão informativa. Neste trabalho analisam-se respostas binárias, combinando um mecanismo de omissão informativa com um modelo não-paramétrico para as covariáveis contínuas, por meio de uma mistura induzida pela distribuição \\apriori\\ de processo de Dirichlet. No caso em que o interesse recai apenas em momentos da distribuição das respostas, propõe-se uma nova análise de sensibilidade sob o enfoque clássico para respostas incompletas que evita suposições distribucionais e utiliza parâmetros de sensibilidade de fácil interpretação. O procedimento tem, em particular, grande apelo na análise de dados contínuos, campo que tradicionalmente emprega suposições de normalidade e/ou utiliza parâmetros de sensibilidade de difícil interpretação. Todas as análises são ilustradas com conjuntos de dados reais.We present methodological developments to conduct analyses with missing data and also studies designed to understand the results of such analyses. We examine Bayesian and classical sensitivity analyses for data with missing categorical responses and show that the subjective components of each approach can influence results in non-trivial ways, irrespectively of the sample size, concluding that they need to be carefully evaluated. Specifically, we show that prior distributions commonly regarded as slightly informative or non-informative may actually be too informative for non-identifiable parameters, and that the choice of over-parameterized models may drastically impact the results. When there is missingness in explanatory variables, we also need to consider a marginal model for the covariates even if the interest lies only on the conditional model. An incorrect specification of either the model for the covariates or of the model for the missingness mechanism leads to biased inferences for the parameters of interest. Previously published works are commonly divided into two streams: either they use semi-/non-parametric flexible distributions for the covariates and identify the model via a non-informative missingness mechanism, or they employ parametric distributions for the covariates and allow a more general informative missingness mechanism. We consider the analysis of binary responses, combining an informative missingness model with a non-parametric model for the continuous covariates via a Dirichlet process mixture. When the interest lies only in moments of the response distribution, we consider a new classical sensitivity analysis for incomplete responses that avoids distributional assumptions and employs easily interpreted sensitivity parameters. The procedure is particularly useful for analyses of missing continuous data, an area where normality is traditionally assumed and/or relies on hard-to-interpret sensitivity parameters. We illustrate all analyses with real data sets.

Texto completo da fonteResumo:
A multiple case study approach was used to investigate the pattern how
a life mission evolves in lives. The participants were one man and two women
who described themselves as having a meaningful career or a mission in life.
The participants were chosen to portray different careers. The investigation
produced three vibrant, detailed narrative accounts of how a life mission
evolved. Each one is told from the perspective of the individual who
experiences a life mission. The accounts were based on in-depth descriptions
of the experience. Each account was reviewed and validated by the case study
participant.
A comparison of the individual accounts exposed a pattern of
experience that was common to all three cases of those who developed a life
mission. It can be best portrayed as a six stage model, with each stage
possessing unique characteristics and each subsequent stage building on the
preceding one. Further, in each case, the development of a life mission
exhibited a process that was more dialectical than lineal in nature.
Several theoretical implications emerge from this study. First, it
supports those models that describe the development of meaning or mission in
life from the standpoint of both a general pattern of experience and a general
pattern of process. This combination was illustrated remarkably in Cochran's
(1990) description of the phases of life for persons with a sense of vocation. Furthermore, the current study's general pattern of process strongly followed
Charme's (1984) account of how meaning evolves in lives.
Second, the accounts suggest that the meaning of one's life mission can
be discovered in a life issue that emerges early in a person's life. This life
issue runs through the person's life guiding his or her engagement in activities
and a career(s), until he or she transcends the life issue through the
clarification of a mission in life.
Third, the accounts do not support the idea that a life mission or
discovering what makes life meaningful is a nebulous, elusive and abstract
endeavour. From a practical perspective, through integrating them, the
general pattern of experience and the general pattern of process can serve as
a guide for those who are searching for a mission or meaning in life and for
those who counsel them.

Differential item functioning (DIF) is an area of continuous interest within the community of measurement researchers. Recently, there is some interest in the detection of DIF items when missing data are present in the test. Under such circumstances, different treatments on the missing data may have different effects on the detection of DIF items. This article describes the results of a simulation study to investigate the impact of missing data pattern on the detection of uniformly DIF items. In the study, missing data pattern is defined by means of various missing mechanisms and missing rates. The purpose of this study is to investigate how two missing data treatments (utilizing single imputation or not) interact with four methods of DIF detection (Mantel-Haenszel statistic and Lord’s chi-square test with and without purification) under four missing mechanisms (MCAR and three versions of MAR) and three missing rates (0%, 10%, 30%) with three DIF magnitude (0, 0.5, 0.8) by means of examining the type I error rates as well as the statistical power of DIF detection. Results show that missing data pattern has impact on the detection of DIF, but only with respect to MH. After missing data treatment by SI, most type I error rates and statistical power increase. With respect to both MH and Lord’s approaches, purification procedure could improve on their DIF detection performances.

Pattern recognition may be described as the process of making a decision based on data input. This is certainly a very huge domain with many practical applications in many fields of science. A specific distance measure which is invariant to different transformations, proposed by Simard et al. (1993) and called Tangent Distance (TD). It is to estimate the minimum distance between two patterns by using different direction of tangent vectors. In this research, we combine TD method with the new ideas. One is called Pseudo Missing Value. The key idea of it is to remove a certain region in the image to help classification. In experimental results for subset of Zip Code data, the best error rate is 0.197 that is slightly better than the result of TD method (0.206). Another idea is called local transformation. The main idea is to cut invariant transformations of TD method into two parts and give a new metric of distance. In experimental results, there are sixteen error rates of two classes recognition lower than it from TD method in the subset of Zip Code data. Furthermore, there are four error rates of two classes recognition lower than it from TD method in the Zip Code data. Here, we use one of typical handwritten digit recognition data set which is called Zip Code data set to demonstrate our methods. The digits were written by many different people with a great variety of writing styles and instruments. Two sets are available, one training set containing 7291 digits and one test set containing 2007 digits. Besides, classification problems in the wafer bin map is an important task. So we try to consider invariant transformations of TD method to the wafer map data.

Texto completo da fonteResumo:
A number of methods have been developed to analyze longitudinal data with dropout. However, there is no uniformly accepted approach. Model performance, in terms of the bias and accuracy of the estimator, depends on the underlying missing data mechanism and it is unclear how existing methods will perform when little is known about the missing data mechanism.
Here we evaluate methods for estimating change over time in longitudinal studies with informative dropout in three settings: using a linear mixed effect (LME) estimator in the presence of multiple types of dropout; proposing an update to the pattern mixture modeling (PMM) approach in the presence of imprecision in identifying informative dropouts; and utilizing this new approach in the presence of prognostic factor by dropout interaction.
We demonstrate that amount of dropout, the proportion of dropout that is informative, and the variability in outcome all affect the performance of an LME estimator in data with a mixture of informative and non-informative dropout. When the amount of dropout is moderate to large (>20% overall) the potential for relative bias greater than 10% increases, especially with large variability in outcome measure, even under scenarios where only a portion of the dropouts are informative.
Under conditions where LME models do not perform well, it is necessary to take the missing data mechanism into account. We develop a method that extends the PMM approach to account for uncertainty in identifying informative dropouts. In scenarios with this uncertainty, the proposed method outperformed the traditional method in terms of bias and coverage.
In the presence of interaction between dropout and a prognostic factor, the LME model performed poorly, in terms of bias and coverage, in estimating prognostic factor-specific slopes and the interaction between the prognostic factor and time. The update to the PMM approach, proposed here, outperformed both the LME and traditional PMM.
Our work suggests that investigators must be cautious with any analysis of data with informative dropout. We found that particular attention must be paid to the model assumptions when the missing data mechanism is not well understood.

"Analysis of health-related quality of life data in clinical trial with non-ignorable missing based on pattern mixture model". Thesis, 2006. http://library.cuhk.edu.hk/record=b6074225.
Texto completo da fonteResumo:
Conclusion. The missing data is a common problem in clinical trial. The methodology development is urgently needed to detect the difference of two treatments drug in patient quality of life. The modified pattern mixture model incorporating generalized estimating equation method or multiple imputation method provides a solution to tackle the non-ignorable missing data problem. Different clinical trials with various treatment schedules, missing data patterns will be formed. Further studies are needed to study the optimal choice of patterns under the methods.Introduction. Health-related Quality of Life (HRQoL) has now been included as a major endpoint in many cancer clinical trials in addition to the traditional endpoints such as tumor response and survival. It refers to how illness or its treatment affects patients' ability to function and whether it induces symptoms. Toxicity, progression and death are common outcome affecting patient's QOL in cancer trial. Since this type of missing data are not occurred at random and are called non-ignorable missing data, conventional methods of analyses are not appropriate. It is important to develop general methods to deal with this problem so that treatment effectiveness for improving patient's QOL or those with serious side effect that is detrimental to patient's QOL can be identified.
Methods. The generalized estimating equation based on modified pattern mixture model is constructed to deal with non-ignorable missing data problem. We conducted a simulation study to examine performance of the model for different types of data. Two scenarios were examined. The first case assumes that two groups have quadratic trend but with different rates of change. The second case assumes that one group has linear trend with time while the other group has quadratic trend with time. Moreover, the second methodology is the multiple imputation based on modified pattern mixture model. The main idea is to resample the data within each pattern to create the full data set and use the standard method to analyze the data. Comparison between two methods was carried out in this study.
Recently, joint models for the QOL outcomes and the indicators of drop-outs are used in longitudinal studies to correct for non-ignorable missing. Two broad classes of joint models, selection model and pattern mixture model, were used. Most of the methodology has been developed in the selection model while the pattern mixture model has attracted less attention due to the identifiability problem. Although pattern mixture model has its own limitation, a modified version of this model incorporating Generalized Estimating Equation can be used in practice.
Result. The power of generalized estimating equation alone is higher than pattern mixture model when the missing data is missing at random. Moreover, the bias of generalized estimating equation is less than that of pattern mixture model when the missing data is missing at random. However, the pattern mixture model performs well when the missing data is missing not at random. On the other hand, the modified pattern mixture model has higher power than the standard pattern mixture model if one group has quadratic trend and other group has linear trend. However, the power of modified pattern mixture model is similar or worst than the standard when the data is both quadratic trends with different rates of change. On the other hand, the results of multiple imputation based on modified pattern mixture model were similar but the power was less than the generalized estimating equation model.

The number of global natural disasters in the past decade is far more than the average state. In recent years the most serious and the largest-casualty natural disaster in Taiwan is 921 earthquake in 1999. Earthquake still can not be forecasted and avoided in advance, so the number of deaths and heavy casualties remain high above the other natural disaster. Ministry of National Defense, ROC, formally listed "disaster prevention and protection" as one of the main missions in 2011 national defense report, and established many the laws and regulations to regulate the tasks of disaster prevention and response countermeasures in military local command centers. However, the experience of dealing with heavy-casualty earthquake disaster for army still stays in the same status as 921 earthquake. In addition, after the promotion of "Jingshi Program", "Jingjin Program" and "Jingtsui Program" organizational transformation, and the more 921 earthquake disaster rescue staffs were retired over years, many military plans and regulations for earthquake disaster prevention and protection may not be effective and efficient. Therefore, according to the plans of disaster prevention and response countermeasures in military local command centers, this work applies DoDAF architecture framework, which is broadly used in enterprise architecture of DoD industry, to systematically develop the process model of responsing earthquake over 5.0 on the Richtcher Scale. We propose the executable model and simulation model on the human rescue activity case, and execute simulation to analyze the relation between deployment of human resource and rescue efficiency, obtaining the suitable number of workers in each work group in military local command centers. This study found that when a single hour occuring disaster event number over 18 or daytime average disaster event number over 16 times per hour, commander should be immediately increaseing deployment for additional workers in military local command centers. The result can provide military local command centers for planning and decision-making reference in future large-scale earthquake disaster.

The policy of Separate Development and its forceful implementation by the Nationalist Government from the !960's and into the 1980's resulted in the resettlement of thousands of Africans in the 'homeland' Ciskei in the Eastern Cape. All these changes had a profound and very often a disruptive influence on the lives of those involved. People's ability to survive amidst these circumstances, was tested to the limit. This study looks at the role of the local Christian faith community in supporting its members during these rapid and disruptive socioeconomic and political changes. The study is confined to two congregations of the Uniting
Reformed Church in Southern Africa in Ilitha and Ndevana in the Eastern Cape. Following an introductory chapter, Chapter 2 gives a historical outline of developments in the broader Ciskei. Attention is also given to demographic, social and economic conditions. Chapter 3 describes the culture and feeling of despair, powerlessness and mistrust that is deeply
entrenched in the minds of many people in the community due to depressive socio-economic situations. Chapter 4 gives an overview of the churches in the area and describes the supportive structures
and actions of two churches in the Ilitha-Ndevana area. No instant solutions are offered to members but through mutual support they find a sense of belonging and encouragement in the midst of their hardship.
In Chapter 5 a model for the mission of the local church in a context of social and economic change and disruption, is presented. It is shown how the image of Christianity and the Gospel have been distorted and misused in the past through the entanglement of mission and
colonialism, a negative attitude towards African culture, and by contributing to the subordination of women in society. A vision that people in Africa can have peace and dignity and become self-reliant is proposed. Within the local faith community this vision is built on an
understanding of God as the weak and suffering Lord, on fellowship and mutual support, a new reading of the Bible, a practical community based spirituality, and an emphasis on healing.Die daarstelling en .kragdadige toepassing van die beleid van Afsonderlike Ontwikkeling vanaf die 1960's tot·die 1980's het tot gevolg_gehad dat duisende Swart Suid-AftilCaners hervestig is in die Ciskei-tuisland in die Oos-Kaap. Al hierdie veranderinge het verreikende en baie dikwels ontwrigtende gevolge op die betrokkenes gehad. Mense se vermoens om binne hierdie omstandighede te oorlee:t: is tot die uiterste beproef. Hierdie studie kyk na die rol van die plaaslike · Cbristelike. geloofsgemeenskap in die ondersteuning van sy lede tydens snelle en ontwrigtende sosiale, ekonomiese en politieke veranderinge. Die studie is beperk tot twee gemeentes van die Verenigende Gereformeerde Kerk in Suider-Aftika in Ilitha en Ndevana in die Oos-Kaap. Na 'n inleidende hoofstuk, gee hoofstuk 2 'n historiese oorsig van ontwikkelinge in die breere Ciskei-gebied. Aandag word ook gegee aan demografriese, sosiale en ekonomiese toestande. Hoofstuk 3 beskryf 'n kultuur en gevoel van moedeloosheid, magteloosheid en wantroue wat, as gevolg van neerdrukkende sosiaal-ekonomiese toestande, diep in menige mense se gemoedere vasgele is. Hoofstuk 4 gee 'n oorsig oor die kerke in die gebied en beskryf die ondersteunende strukture en optrede in twee gemeentes in die Ilitha-Ndevana area. Geen kitsoplossings word aan lede aangebied nie, maar deur onderlinge steun vind hulle geborgenheid en bemoediging te midde van swaarkry. In hoofstuk 5 word 'n model aangebied vir die missie van die plaaslike kerk te midde van sosiale en ekonomiese veranderinge en ontwrigting. Daar word aangetoon hoe die beeld van die Christendom in die verlede verwring en misbruik is deur: die verstrengeling van sending en kolonialisasie; 'n negatiewe houding teenoor kultuur in Afrika; en deur by te dra tot die ondergeskikte posisie van vroue in die samelewing. 'n Visie dat die mense van Afrika vrede en menswaardigheid kan geniet en self onderhoudend kan raak, word voorgestel. Binne die plaaslike geloofsgemeenskap word aan hierdie visie gebou deur 'n begrip van God as die magtelose en lydende Here, deur onderlinge gemeenskap en ondersteuning, 'n nuwe lees en begrip van die Bybel, 'n praktiese gemeenskaps-gerigte spiritualiteit en 'n beklemtoning van heling en herstel.

erarbeitetThis dissertation examines the relationship between theological education and missionary challenges in German-speaking Europe. The central research question is what the changing context and related missionary challenges of the church signify for a reform of theological training. Voices from an ecumenical and evangelical perspective are demanding a reform of theological education towards a missional approach, an approach defined in its identity as well as its function from the Missio Dei. The following study pursues the question as to what such demands entail and what implications follow for theological education in general. The first part presents the ecumenical, evangelical and evangelic impulse towards a reform of theological education and a link with missionary challenges; theoretic sensibilities and key categories are developed for the empirical examination. The main section of the study examines the abovementioned question through a qualitative-empirical study of the leadership of evangelical theological educational establishments in German-speaking Europe. With the help of half-standardised interviews of experts, four action samples were presented as possible reactions, according to grounded theory and by means of typology development. Finally, the results of the empirical examination were evaluated in the light of the literature and a missional-empirical evaluation was made regarding the theology, the learning theory and the competence orientation of a missional-theological education. This dissertation thus makes a threefold contribution. Firstly, it constitutes ecumenical, evangelical and evangelic contributions and an empirically developed plan of action on the theme of the reform of theological education in light of missionary challenges. Secondly, it offers a contribution from a missional- empirical perspective to the discussion of a possible reform of theological education. Thirdly, it develops a concrete impetus towards the theology, learning theory and competence orientation of a missional theological education in the German-speaking context
