Full textAbstract:
Background: Apache Cassandra is a highly scalable distributed system that can handle large amounts of data through several nodes / virtual machines grouped together as Apache Cassandra clusters. When one such node in an Apache Cassandra cluster is down, there is a need for a tool or an approach that can identify this failed virtual machine by analyzing the data generated from each of the virtual machines in the cluster. Manual analysis of this data is tedious and can be quite strenuous. Objectives: The objective of the thesis is to identify, build and evaluate a solution that can detect and report the behaviour of the erroneous or failed virtual machine by analyzing the data generated by each virtual machine in an Apache Cassandra cluster. In the study, we analyzed two specific data sources from each virtual machine, i.e., the wait reports and Apache Cassandra statistics, and proposed a tool named AnoDect to realize this objective. The tool has been built using the input provided by the technical support team at Ericsson through interviews and was also evaluated by them to realize its reliability, usability and, usefulness in an industrial setting. Methods: A case study methodology has been piloted at Ericsson and semi-structured interviews have been conducted to identify the key features in the data along with the functionalities AnoDect needs to perform to assist the CIL team (technical support team at Ericsson) to rectify the erroneous virtual machine in the cluster. An experimental evaluation and a static user evaluation have been conducted, as a part of the case study evaluation, where the experimental evaluation is conducted to identify the best technique for AnoDect's anomaly detection in wait reports and the static evaluation has been conducted to evaluate AnoDect for its reliability and usability once it is deployed for use. Results: From the feedback provided by the CIL team through the questionnaire, it has been observed that the results provided by the tool are quite satisfactory, in terms of usability and reliability of the tool.

Full textAbstract:
In this thesis I carry out an encompassing analysis of the problem of measurement error in retrospectively collected work histories using data from the “Longitudinal Study of the Unemployed”. This dataset has the unique feature of linking survey responses to a retrospective question on work status to administrative data from the Swedish Register of Unemployment. Under the assumption that the register data is a gold standard I explore three research questions: i) what is the prevalence of and the reasons for measurement error in retrospective reports of unemployment; ii) what are the consequences of using such survey data subject to measurement error in event history analysis; and iii) what are the most effective statistical methods to adjust for such measurement error. Regarding the first question I find substantial measurement error in retrospective reports of unemployment, e.g. only 54% of the subjects studied managed to report the correct number of spells of unemployment experienced in the year prior to the interview. Some reasons behind this problem are clear, e.g. the longer the recall period the higher the prevalence of measurement error. However, some others depend on how measurement error is defined, e.g. women were associated with a higher probability of misclassifying spells of unemployment but not with misdating them. To answer the second question I compare different event history models using duration data from the survey and the register as their response variable. Here I find that the impact of measurement error is very large, attenuating regression estimates by about 90% of their true value, and this impact is fairly consistent regardless of the type of event history model used. In the third part of the analysis I implement different adjustment methods and compare their effectiveness. Here I note how standard methods based on strong assumptions such as SIMEX or Regression Calibration are incapable of dealing with the complexity of the measurement process under analysis. More positive results are obtained through the implementation of ad hoc Bayesian adjustments capable of accounting for the different patterns of measurement error using a mixture model.

Full textAbstract:
As the software industry grows larger by the minute, the need for automated solutions within bug report management is on the rise. Although some research has been conducted in the area of bug handling, new, faster or more precise approaches are yet to be developed. A bug report typically contains a free text observations field where the issue can be described by a human. Research regarding processing of this type of field is extensive, however, bug reports are often accompanied with system log files which have been given less attention so far. In the 4G LTE telecommunications network, the available system log files are many and several are likely to aid the routing of bug reports. In this thesis, one system log file was chosen to be evaluated; the alarm log. The alarm logs are time series count data containing alarms raised by the system. The alarm log data have been pre-processed with data mining techniques. The Apriori algorithm has been used to mine for specific alarms and alarming objects which indicates that the bug report should be solved by a particular developer group. We extend the Apriori algorithm to a temporal setting by using a customised time dependent confidence measure. To further mine for interesting sequences of events in the logs, the sequence mining approach SPADE has been used. The extracted class-associated sequences from both pre-processing approaches are transformed into binary features possible to use as predictors in any prediction model. The results have been evaluated by predicting the correct developer group with two different methods; logistic regression and DO-probit. Logistic regression was regularised with the elastic net penalty to avoid computational issues as well as handling the sparse covariate set. DO-probit was used with a horseshoe prior; it is well suited for the sparse covariate regression problem as it is customised to obtain signals in sparse, noisy data. The results indicate that a data mining approach for processing alarm logs is promising. The results show that the rules obtained with the Apriori mining process are suitable for mining the alarm logs as most binary representations of the rules used as covariates in logistic regression are kept in the equations for the expected classes with strongly positive coefficients. Although, the overall improvement in accuracy from using the alarms logs in addition to the learned topics from free text fields is modest, the alarm logs are concluded to be a good complement to the free text information as some Apriori covariates appears to be better suited to predict some classes than some topics.

Resumo: Esta investigação de mestrado é um estudo qualitativo multicêntrico, marcado pelo referencial da fenomenologia e da hermenêutica e tem como objetivo compreender como psiquiatras trabalhadores da rede de serviços públicos de saúde mental lidam com a dimensão da experiência particular de pessoas diagnosticadas como portadoras de esquizofrenia no desenho do cuidado. Temos como pressuposto que para promover o restabelecimento de pessoas com transtornos mentais graves e reduzir o estigma é necessário desenvolver modos de cuidar em que a própria experiência da doença não seja negada. Por isso este trabalho foi apoiado na noção de recovery, que no cenário internacional tem contribuído para valorizar a dimensão da experiência do usuário. Para cumprir nosso objetivo, além de realizar uma revisão sobre o conceito de recovery, a fim de melhor compreende-lo, realizamos grupos focais com psiquiatras dos municípios de Campinas e Rio de Janeiro, e através desses grupos pretendemos acessar a experiência dos psiquiatras na formulação do diagnóstico de esquizofrenia e proposição do tratamento. Através do material produzido neste estudo pudemos perceber que a formulação do diagnóstico de esquizofrenia exerce grande impacto sobre a experiência de cuidar do usuário. E a concepção de esquizofrenia como doença grave e crônica parece influenciar amplamente o tipo de assistência que estes profissionais irão ofertar, assim como as expectativas que terão em relação à vida futura do usuário. A idéia de tratamento dos psiquiatras parece permeada não pela idéia de recovery, mas pelos princípios e objetivos da reabilitação psicossocial em seu sentido mais ortopédico e normalizante, que tem grande compatibilidade com o modelo biomédico, e oferece poucas ferramentas de acesso ao mundo e à experiência do usuário
Abstract: This master research is a qualitative multiside study, marked by the reference of phenomenology and hermeneutics, and aims to understand how psychiatrists of community-based mental health services deal with the dimension of the particular experience of people diagnosed as suffering from schizophrenia in the caring process. We have assumed that to facilitate the recovery of people with severe mental disorders and to reduce stigma is necessary to develop ways of caring in which the very experience of illness is not ignored. Therefore this work was supported by the notion of "recovery", which in the international arena has contributed to enhance the meaning of the user experience. To accomplish our goal, besides doing a review on the concept of recovery in order to better understand it, we conducted focus groups with psychiatrists from Campinas and Rio de Janeiro. In these groups we intended to access to the experience of psychiatrists in formulating diagnosis of schizophrenia and treatment proposition. Based on the material produced in this study, we realized that the formulation of schizophrenia diagnostic has a major impact on the experience of caring user. And the concept of schizophrenia as a chronic and severe illness seems to largely influence the type of care these professionals will offer, as well as the expectations they have regarding the future life of the user. The psychiatrists? idea of treating seems to be permeated not by the idea of recovery, but by the principles and goals of psychosocial rehabilitation in its most orthopedic and normalizing sense, which has great compatibility with the biomedical model, and provides few tools to access the world and experience of the user

Full textAbstract:
In self-report data, participants who provide incorrect responses are known as intentional inaccurate responders. This dissertation provides statistical analyses for address intentional inaccurate responses in the data.
Previous work with adolescent self-report, labeled survey participants who intentionally provide inaccurate answers as mischievous responders. This phenomenon also occurs in clinical research. For example, pregnant women who smoke may report that they are nonsmokers. Our advantage is that we do not solely have self-report answers and can verify responses with lab values. Currently, there is no clear method for handling these intentional inaccurate respondents when it comes to making statistical inferences.
We propose a using an EM algorithm to account for the intentional behavior while maintaining all responses in the data. The performance of this model is evaluated using simulated data and real data. The strengths and weaknesses of the EM algorithm approach will be demonstrated.

Quantitative studies aiming to disentangle public corruption effects often emphasize the lack of objective information in this research area. The CGU Random Audits Anti-Corruption Program, based on extensive and unadvertised audits of transfers from the federal government to municipalities, emerged as a potential source to try to fill this gap. Reports generated by these audits describe corrupt and mismanagement practices in detail, but reading and coding them manually is laborious and requires specialized people to do it. We propose a statistical framework to guide the use of text data to construct objective indicators of corruption and use it in inferential models. It consists of two main steps. In the first one, we use machine learning methods for text classification to create an indicator of corruption based on irregularities from audit reports. In the second step, we use this indicator in a regression model, accounting for the measurement error carried from the first step. To validate this framework, we replicate an empirical strategy presented by Ferraz et al. (2012) to estimate effects of corruption in educational funds on primary school students’ outcomes, between 2006 and 2015. We achieved an expected accuracy of 92% on the binary classification of irregularities, and our results endorse Ferraz et al.. findings: students in municipal schools perform significantly worse on standardized tests in municipalities where was found corruption in education.
Estudos quantitativos em corrupção política enfatizam a falta de informações objetivas nessa área de pesquisa. O Programa de Fiscalização por Sorteios Públicos da CGU se baseia em auditorias não anunciadas das transferências do Governo Federal para municípios, e aparece como uma potencial solução para essa lacuna. Relatórios gerados durante essas auditorias descrevem com detalhe práticas de corrupção e de má gestão pública. No entanto, a análise manual desses relatórios é penosa e requer o conhecimento de especialistas. Nós propomos um framework estatístico para guiar o uso desses dados textuais na construção de indicadores objetivos de corrupção e em modelos de inferência. O framework consiste em duas etapas gerais. Na primeira, usamos métodos de aprendizagem de máquinas para classificação das irregularidades constatadas durante as auditorias. Na segunda etapa, construímos um indicador de corrupção baseado na classificação e o utilizamos em um modelo de regressão, ajustando pelo erro de medida derivado da primeira etapa. Para validar essa metodologia, nós replicamos a estratégia empírica apresentada por Ferraz et al. (2012) para estimar o efeito da corrupção em fundos educacionais nos resultados escolares de alunos do Ensino Fundamental, entre os anos de 2006-2015. Nós obtemos uma acurácia média de 92% na classificação binária de irregularidades, e nossos resultados corroboram com os encontrados em Ferraz et al.: estudantes de escolas municipais apresentam resultados significativamente piores em testes padronizados se estudam municípios com indícios de corrupção na área de educação

The purpose of the current study was to investigate the structural relationships among self-reported mathematics achievement, attitudes toward statistics, and statistics outcomes by testing a structural model. The current study utilized a survey design. The participants of study consisted of 247 undergraduate and graduate students enrolled in statistics courses in a university in Turkey. The participants were from different disciplines such as engineering, education, and economics. The Turkish version of the Survey of Attitudes toward Statistics-36©(SATS-36©
) was used to collect data. The SATS-36©
assessed six components of statistics attitudes: cognitive competence, value, difficulty, effort, interest, and affect. Higher scores of the six components referred to the more positive attitudes. In addition, the SATS-36©
involved additional items to measure students&rsquo
self-reports of mathematics achievement and statistics outcomes. Results of the descriptive statistics analyses revealed that participants of the study had positive attitudes toward statistics except that they had neutral perceptions about the difficulty of statistics and neutral interest in statistics. Statistics outcomes variable was significantly correlated with mathematics achievement, affect, value, interest, and effort variables. Structural equation modeling was used to test the hypothesized structural regression model. Results indicated that affect, value, cognitive competence, and interest variables had large total standardized effects on statistics outcomes variable. Mathematics achievement and the effort variables had small total effects on explaining statistics outcomes. Difficulty had no statistically significant total effect on explaining statistics outcomes. Overall, the hypothesized structural regression model explained 66% of the total variance in statistics outcomes, which was statistically significant.

Small, Neil. "A statistical method for determining and representing formability : innovation report." Thesis, University of Warwick, 2015. http://wrap.warwick.ac.uk/80224/.
Full textAbstract:
Formability, conventionally characterised by the Forming Limit Curve (FLC), is a critical measure used to define the working limit of sheet metal in a forming operation. The FLC defines the limit strain the material can undergo before failure occurs. The importance of this failure criterion means it is used at various stages in the development of automotive body panels: during material selection; during stamping simulations; and in the purchase of stamping tools before commencing serial production. To mitigate against the risk that the FLC is positioned incorrectly; that mechanical property variation between blanks causes reduced formability; and that conditions imposed by the stamping operation itself cause premature failure, a safety margin is introduced. The size of the safety margin is based on the industrial sponsor’s prior experience and attitude to risk, as opposed to an objective analysis of each of the risks posed to formability. Uncertainty around the position of an FLC arises from the dispersed limit strains that characterise the results of standardised formability tests. The aim of this research was to understand and characterise the uncertainty of the formability test, and develop a more accurate and precise method for determining and representing formability. Initial tests were carried out according to the standard ISO method, and a digital image correlation (DIC) technique was used to measure full-field strains on each specimen throughout the tests. Two observations were made. Firstly, the method of analysis advocated by the ISO standard requires subjective interpretation to define a limit strain. Secondly, the full-field strain measurements showed a “noisy” strain distribution overlaid over the expected strain field. This “noise” was significant compared to the uncertainty of the DIC instrument. A solution was developed by adopting a statistical attitude to model surface strain measurements. Strains from the beginning of deformation up to fracture were characterised by a fundamental analysis. The analysis showed that the forming limit of an individual test is statistical in nature, and that the strains’ statistical character exhibits recognisable trends that evolve from the start of the tests up to necking. A new 'time-dependent' method based on the innovative application of a Gaussian Mixture Model (GMM) was developed to characterise these trends, and quantify the forming limit. The GMM was used to objectively identify the locus of a localised neck; identify the onset of necking; and characterise the neck at the forming limit. Rather than selectively analysing strains in a pre-determined area of a specimen, and at a selected time of the test, the developed technique eliminates the subjectivity that is required by the current ISO-standard method. The new GMM technique describes formability as a probabilistic risk of failure. Strain measurements made on single specimens were turned into a complimentary statistical formability criterion using the logistic regression technique proposed by Strano & Colosimo (2006). Formability Maps (FMs) were constructed to show the probability of failure contours on the Forming Limit Diagram (FLD). FMs derived from the GMM provide the precise representation of formability that is missing from the FLC, and that is required to objectively interpret the risk of failure for an industrial panel. It was postulated that the presence of a surface roughness is responsible for surface strain variation because of the geometry of its asperities. Its evolution is controlled by underlying changes to the microstructure during the course of plastic deformation. A modified M-K model was used to predict the range of strains that arise from surface roughening at the forming limit. Formability predictions correspond well to FLCs drawn from ISO-standard limit strains, but less well to the FMs drawn from the GMM. It was concluded that surface roughening alone does not explain the heterogeneous strain behaviour measured in this research.

We present a methodology for improving the detection of outlying Fire Service’s reports based on domain knowledge and dialogue with Fire & Rescue domain experts. The outlying report is considered as element which is significantly different from the remaining data. Outliers are defined and searched on the basis of domain knowledge and dialogue with experts. We face the problem of reducing high data dimensionality without loosing specificity and real complexity of reported incidents. We solve this problem by introducing a knowledge based generalization level intermediating between analysed data and experts domain knowledge. In the methodology we use the Formal Concept Analysis methods for both generation appropriate categories from data and as tools supporting communication with domain experts. We conducted two experiments in finding two types of outliers in which outliers detection was supported by domain experts.

Information presented in site investigation reports has a strong influence in design, project costs and safety. For this reason, both the quality and the reliability of site investigation reports are important. However in our country, geotechnical engineering is relegated to second place and site investigation studies, especially parcel-basis ground investigation worksdo not receive the attention they deserve. In this study, site investigation reports, that are required for the license of design projects, are examined and the missing/incorrect site investigations, laboratory tests, geotechnical evaluations and geotechnical suggestions that occur in the reports are catalogued. Also, frequency of each mistake is statistically examined

Resumo: Neste trabalho, comparamos diversas técnicas de previsão de IBNR (Incurred But Not Reported) para dados de um triângulo Run-OjJ, desde as mais simples, como por exemplo as técnicas Chain- Ladder e a técnica da Separação, até as técnicas mais sofisticadas, considerando modelos Log-Normais ou pela distribuição Poisson Composta. Além disso, nosso trabalho enfatiza a necessidade do uso de técnicas não-paramétricas, considerando um modelo de truncamento das variáveis. Foi possível mostrar que, mesmo não tendo nenhuma informação sobre a distribuição dos dados, é possível estimar o IBNR com menor erro e variabilidade do que as técnicas usuais conhecidas. Para fazer as comparações, foram realizadas simulações de sinistros ocorrendo através de um Processo de Poisson não homogêneo, e com dependência no tempo de relato e valor do sinistro. A medida de comparação utilizada foi o Erro Quadrático Médio (EQM) entre os valores simulados e os valores previstos por cada técnica. A abordagem paramétrica, quando os dados provém de uma distribuição Poisson Composta, apresentou o menor EQM dentre todas as técnicas. Entretanto, se não há informação sobre a distribuição dos dados, a técnica de Mista de truncamento foi a melhor entre as não-paramétricas
Abstract: We compare several forecast techniques for IBNR(Incurred But Not Reported) from a Run-Off triangle data, since the most simple techniques like Chain-Ladder and Separation Technique, to the more complex using Log-Normal models and Compound Poisson distribution. Therefore, exist the necessity of the use of Nonparametric techniques, using a model that consider variable Truncation. It was possible shown that, when we don't have any information about the data, it's possible estimate de IBNR forecasting with less mistake and variability than the usual techniques. For make the forecasting, we used claims simulations occurring by a nonhomogeneous Poisson process and with dependence entry the time to report and value paid for one claim. The measure of comparison used was the Mean Square Error (MSE) of simulated values and forecasting values for each technique. The parametric boarding when the data come from a Compound Poisson distribution, was the best MSE entry all techniques. However, when we don't have any information about the data, the Truncation Technique was the best of the nonparametric techniques

Introduction: Crime victimization is a problem affecting both individuals and societies. Previous research has looked at the associations between victimization and other factors, and many countries employ self-reported victimization surveys to establish what the victimization patterns look like at different societal levels. Aims: By examining victimization proportions and patterns, this study aimed to further the understanding of what the crime victimization problem looks like in a medium-sized Swedish city. Method: 149 men and 146 women, for a total of 295 inhabitants of Sundsvall, answered self-reported victimization surveys based on the Swedish Crime Survey. The gathered data was subsequently quantified and analyzed. Results: In total, 11.9 % of the sample reported some type of victimization. Overall, men were more likely to be victimized than women, and crimes against persons were more common than crimes against property. Occupation and socio-economic status were significantly associated with victimization. More than half of the victimizations were not reported to the police, and victimization was significantly associated with a lower trust in the criminal justice system and the police. Conclusion: Medium-sized cities like Sundsvall seem to have considerably lower proportions of victimization than the counties, regions and nation as a whole. The rates of reporting and patterns of victimization found, however, are in accord with findings on other societal levels and could to some extent be explained through the principles of the routine activities/lifestyle theory.2017-06-01

The South African wildlife tourism industry is based on trophy hunting and together with international wildlife trade it can represent a major treat to biodiversity conservation. Annually, thousands of hunters participate in hunting activities in South Africa and thousands of trophy items are traded across international borders. This research is a result of comprehensive quantitative analysis in how far data of trophy hunting kills and data of trophy export are consistent on the example of South Africa. Data were extracted from 2 different sources: trade data reported under the CITES Trade Database on export of trophy items from South Africa within the year 2018; South African Professional Hunting statistics (SAPHs) containing trophy kills information for each species and the country of origin of the hunter. In the year 2018, a total of 3,126 hunting trophy items of 28 endangered taxa were exported out of South Africa to 37 countries that contributed to trophy hunting trade in South Africa. However, 64 countries participated in trophy hunting of endangered taxa in South Africa and a total of 4,726 trophy kills of 28 trophy-hunted endangered taxa were reported. Therefore, the level of inconsistence in data of trophy hunting kills and data of trophy hunting export is significant and differs to varying degrees across the countries contributing to trophy hunting and CITES-listed trophy-hunted species. This research provides possible reasons for the inconsistency and propose recommendations for improving the CITES reporting system.2020-06-10

In recent years, it has been observed that software clones and plagiarism are becoming an increased threat for one?s creativity. Clones are the results of copying and using other?s work. According to the Merriam – Webster dictionary, “A clone is one that appears to be a copy of an original form”. It is synonym to duplicate. Clones lead to redundancy of codes, but not all redundant code is a clone.On basis of this background knowledge ,in order to safeguard one?s idea and to avoid intentional code duplication for pretending other?s work as if their owns, software clone detection should be emphasized more. The objective of this paper is to review the methods for clone detection and to apply those methods for finding the extent of plagiarism occurrence among the Swedish Universities in Master level computer science department and to analyze the results.The rest part of the paper, discuss about software plagiarism detection which employs data analysis technique and then statistical analysis of the results.Plagiarism is an act of stealing and passing off the idea?s and words of another person?s as one?s own. Using data analysis technique, samples(Master level computer Science thesis report) were taken from various Swedish universities and processed in Ephorus anti plagiarism software detection. Ephorus gives the percentage of plagiarism for each thesis document, from this results statistical analysis were carried out using Minitab Software.The results gives a very low percentage of Plagiarism extent among the Swedish universities, which concludes that Plagiarism is not a threat to Sweden?s standard of education in computer science.This paper is based on data analysis, intelligence techniques, EPHORUS software plagiarism detection tool and MINITAB statistical software analysis.

Full textAbstract:
Denna studie syftar till att utgöra underlag och förslag till utformningen av statistikrapporter till WoodEye’s nya statistikdatabas som ingår i WoodEye 5. WoodEye 5 lanserades på Lignamässan i Hannover, 30 maj- 3 juni 2011. Förslagen har sin grund i kvalitativa intervjuer med ett urval av Innovativ Vision AB’s kunder, som tidigare visat intresse i frågan. Innovativ Visions kunder finns inom träbearbetningsindustrin, och uppvisar stora variationer i verksamhetsområde. Därför ska den nya statistikdatabasen präglas av en större valfrihet och flexibilitet, för att ett specifikt företag ska kunna göra de produktionsuppföljningar som är lämpliga för ändamålet. I slutet av 1960-talet påbörjades utvecklingen av automatisk virkessortering, eftersom detta skulle medföra en högre kapacitet och en jämnare avsyning i träbearbetande företag. En större mängd produkter kan tillverkas och fler sorteringsregler kan tillämpas samtidigt vid automatisk virkesavsyning jämfört med manuell avsyning. På senare år har även träindustrin påverkats av olika produktionsfilosofier, exempelvis resurssnål produktion. Detta medför att arbetet med kvalitetsteknik får en mer betydande roll i träbearbetande företag. Eftersom trä är ett heterogent material, är kvalitetsoptimering en komplex aktion. Därför har man börjat förespråka idén om rätt kvalitet för rätt ändamål, istället för att tala om hög och låg kvalitet. Innovativ Vision har sina rötter i den datorbaserade bildbehandlingen som bedrevs med stor framgång vid Linköpings universitet under 1980-talet. I slutet av 2011 beräknas den femte generationen WoodEye vara i drift, och i dagsläget finns tre tillhörande mjukvaruoptioner; Sorter, CrossCut och Parquet & Flooring. Sorter är en sorteringsoption, CrossCut är en kapoptimeringsoption och Parquet & Flooring är en sorteringsoption med förbättrad avsyning av färgvariationer i virket. I intervjuerna framkommer att de uppföljningar som referensföretagen utför idag är personal-, tillgänglighets-, och leverantörsuppföljningar samt hur den faktiska produktionen förhåller sig till den kalkylerade produktionen. Det finns stora variationer i uppföljningsverksamheten mellan företagen. Tre företag utför leverantörsuppföljningar och dessa anses vara de som har bäst rutin på uppföljningar. För optimalt genomförda uppföljningar av råvaran krävs en utvecklad defektstatistik, en funktion i statistikdatabasen som skulle innebär ett stort mervärde för kunderna. Det är framför allt kunder som använder WoodEye CrossCut som efterfrågar defektstatistik. Det beror sannolikt på att ingen motsvarighet till WoodEye Sorter’s nedklassningsstatistik finns till denna kapoptimeringsoption. I WoodEye 5 kommer trendstatistik genereras. Trendstatistiken blir ett verktyg för att avgöra hur det ögonblickliga produktionsutfallet förhåller sig till produktionsutfallet över tiden. Bland referensföretagen råder delade meningar om hur trendstatistiken kommer att användas; en del företag tror sig vilja göra uppföljningar baserat på informationen, medan andra enbart vill tillämpa den som ett stöd då WoodEye är i drift.This study aims to provide support and suggestions for the design of statistical reports to WoodEye's new statistical database based on interviews with a sample of customers of Innovativ Vision AB. The new databas will be developed because of the improved fifth generation WoodEye 5, that will be in operation in late 2011. The customers varies widely in scope, and therefore the new statistical database should be characterized by a greater freedom of choice. Automatic sorting of wood panels imply a higher capacity and a smoother inspection. A greater variety of products can be produced, and a larger amount of sorting rules can be applied to automatic inspection of wood than in the case of manual inspection. The interviews reveal that there are wide variations in follow-up activities between the companies. The follow-ups the reference companies perform today are primarily whether the actual production is related to the deferred production, personnel monitoring, availability monitoring and supplier monitoring. Many of the companies demand some kind of defects statistics, for optimal follow-up of the raw material.

Full textAbstract:
Les données rapportées par les patients sont maintenant fréquemment utilisées en recherche biomédicale. Ces instruments permettent la mesure de concepts subjectifs tels que la qualité de vie, les niveaux d’anxiété, de douleur, de fatigue. L’interprétation d’une différence de score au cours du temps était basée sur l’hypothèse que le sens des concepts et échelles restai stable au cours du temps dans l’esprit des individus. Cette hypothèse semble aujourd’hui dépassée. L’auto-évaluation d’un concept est maintenant comprise comme contingente de la représentation subjective qu’à un sujet du dit concept, cette représentation pouvant changer au cours du temps, surtout après avoir vécu un évènement de santé : ce phénomène est connu comme le « response shift ». Depuis la fin des années 1990s, l’investigation de ce phénomène est devenue un sujet d’intérêt majeur en psychométrie. Si des développements ont vu le jour, ce sujet reste récent et donc accompagné de débats variés que ce soit sur le plan théorique ou méthodologique. Aussi, l’objectif général de cette thèse est d’investiguer certaines problématiques méthodologiques et statistiques liées au response shift. Ce manuscrit est composé de trois travaux principaux : un état de l’art et une synthèse des travaux conduits à un niveau international depuis que le response shift est étudié, une étude pilote des performances de la procédure d’Oort (une méthode populaire de détection de response shift) par simulations et un travail théorique sur les liens entre response shift et complexité sémantique des concepts mesurés et items utilisésPatient-Reported Outcomes are increasingly used in health-related research. These instruments allow the assessment of subjective concepts such as Health-Related Quality of Life, anxiety level, pain or fatigue. Initially, the interpretation of a difference in score over time was based on the assumption that the meaning of concepts and measurement scales remains stable in individuals’ minds over time. This assumption has been challenged. Indeed, the self-assessment of a concept is now understood as a contingency of the subjective meaning a subject has of this concept, which can change over time especially as a result of a salient medical event: the “response shift” phenomenon. Since the end of the 1990s, researches on response shift phenomenon has become of prime interest in the field of health-related research. If developments have been made, it is still a young field with various scientific debates on a theoretical, methodological and statistical level. Thus, the broad objective of this thesis is to investigate some methodological and statistical issues regarding response shift concept, detection and integration into PRO data analyses. The manuscript is composed of three main works: a state of the art and synthesis of the works conducted at an international level since response shift phenomenon is investigated, a pilot study investigating the statistical performances of the Oort’s Procedure (a popular method of response shift detection using Structural Equation Modeling) by simulations and a theoretical work about the links between response shift occurrence and semantic complexity of concepts measured and items used

Full textAbstract:
The aim of the present study was to investigate the experiences and attitudes concerningpreimplantation genetic diagnosis (PGD) among the couples that have undergone PGD in Sweden.PGD is an alternative to conventional prenatal diagnosis for couples with a high risk of having a childwith genetic disease. Couples opting for PGD have to perform in vitro fertilisation, generatedembryos are subjected to biopsy and diagnosis, and healthy embryos can be transferred to the femaleuterus. Hopefully a pregnancy will be established. However, PGD is a strategy that implies bothphysical and psychological stress, and it is not obvious that this is an easier alternative than prenataldiagnosis. A questionnaire was sent to 116 couples that had carried out at least one PGD treatmentcycle. The response rate was 89%, thus almost all couples treated in Sweden since the start in 1995was represented. Results: The stress, both psychologically and physically, caused by the PGD treatment was evaluatedsomewhere between “As expected” and “More stressful than expected”. The stress experienced duringthe PGD treatments was not associated with the couples’ previous reproductive experiences. The mostphysical stressful event was the oocyte retrieval and the most psychologically stressful period was“waiting for a possibly/ hopefully embryo transfer”.The majority of couples that had performed prenatal diagnosis on a spontaneous pregnancy andexperienced a PGD treatment reported that PGD was more physically stressful (54%), but that prenataldiagnosis was more psychologically stressful (51%). The couples reported the reproductivealternatives chosen after PGD closure, and couples performing PGD at the present rated futurereproductive alternatives. Results indicated that ocyte- and sperm donations were a less attractivealternative than for example adoption. Participants in the study also had the opportunity to state forwhom /which indications PGD should be an option. Conclusion: The stress associated with performing PGD or prenatal diagnosis is extensive and noneof the alternatives is an obvious choice. PGD was reported as more physical stressful, but prenataldiagnosis was more psychologically stressful. The reproductive pathways chosen after PGD closurewas reported, and surprisingly sperm and oocyte donations were not attractive alternatives. The choiceof reproductive alternatives might be influenced by the information and support provided by thehealthcare personal. Knowledge about the experience of PGD treatments is of great importance forthose that meet these couples for genetic and reproductive counselling, in order to give them propercare and to better meet their demand of information and support.

Full textAbstract:
A study investigating what factors are present leading to pilots submitting voluntary anomaly reports regarding their flight performance was conducted. The study employed statistical methods, text mining, clustering, and dimensional reduction techniques in an effort to determine relationships between factors and anomalies. A review of the literature was conducted to determine what factors are contributing to these anomalous incidents, as well as what research exists on human error, its causes, and its management. Data from the NASA Aviation Safety Reporting System (ASRS) was analyzed using traditional statistical methods such as frequencies and multinomial logistic regression. Recently formalized approaches in text mining such as Knowledge Based Discovery (KBD) and Literature Based Discovery (LBD) were employed to create associations between factors and anomalies. These methods were also used to generate predictive models. Finally, advances in dimensional reduction techniques identified concepts or keywords within records, thus creating a framework for an unsupervised document classification system. Findings from this study reinforced established views on contributing factors to civil aviation anomalies. New associations between previously unrelated factors and conditions were also found. Dimensionality reduction also demonstrated the possibility of identifying salient factors from unstructured text records, and was able to classify these records using these identified features.ID: 029050666; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (Ph.D.)--University of Central Florida, 2010.; Includes bibliographical references (p. 168-174).

Full textAbstract:
Patient reported outcomes (PROs) are becoming increasingly important in cancer studies, particularly with the emphasis on patient centered outcome research. However, multiple PROs, using different scales, with different directions of favorability are often used within a trial, making interpretation difficult. To enhance interpretability, we propose the use of a standardized effect size graph, which shows all PROs from a study on the same figure, on the same scale. Plotting standardized effects with their 95% confidence intervals (CIs) on a single graph clearly showing the null value conveys a comprehensive picture of trial results. We demonstrate how to create such a graph using data from a randomized controlled trial that measured 12 PROs at two time points. The 24 effect sizes and CIs are shown on one graph and clearly indicate that the intervention is effective and sustained.

Full textAbstract:
The objective of this thesis was to defend an alternative approach by health policy makers for improving health outcomes through investing on social factors of peoples' lives, rather than by increasing health expenditures. In order to defend this theory, this master thesis addresses two research questions: Which are the social determinants of health with largest impact on health status of individuals? And what is the statistical correlation between those social determinants of health and self-reported health status, and psychological health, for Germany, Denmark, Spain and Ireland? The first question was answered by developing a comprehensive research among the mostrelevant literature in the field of social determinants of health and the second through the construction of a statistical multiple regression model. According this study the social determinants with largest impact on the health status of individuals are: physical activity, education level, the welfare state, emotional support, socio-economic status, living conditions, working conditions, and life balance. Regarding the results of multiple regression models all variables followed the expected trend and it was possible to proof significant statistical correlation in 7 of the 8 determinants chosen, especially in the cases of working conditions and life balance, where those having problems managing these aspects of life experienced 50% or in some cases 30% of the health status of individuals with positive experiences in these life dimensions.

Full textAbstract:
Over the last 5 decades, the retrospective pretest has been used in behavioral science research to battle key threats to the internal validity of posttest-only control-group and pretest-posttest only designs. The purpose of this study was to compare outcome measures resulting from four research design implementations incorporating the retrospective pretest: (a) pre-post-then, (b) pre-post/then, (c) post-then, and (d) post/then. The study analyzed the interaction effect of pretest sensitization and post-intervention survey order on two subjective measures: (a) a control measure not related to the intervention and (b) an experimental measure consistent with the intervention. Validity of subjective measurement outcomes were assessed by correlating resulting to objective performance measurement outcomes. A Situational Leadership® II (SLII) training workshop served as the intervention. The Work Involvement Scale of the self version of the Survey of Management Practices Survey served as the subjective control measure. The Clarification of Goals and Objectives Scale of the self version of the Survey of Management Practices Survey served as the subjective experimental measure. The Effectiveness Scale of the self version of the Leader Behavior Analysis II® served as the objective performance measure. This study detected differences in measurement outcomes from SLII participant responses to an experimental and a control measure. In the case of the experimental measure, differences were found in the magnitude and direction of the validity coefficients. In the case of the control measure, differences were found in the magnitude of the treatment effect between groups. These differences indicate that, for this study, the pre-post-then design produced the most valid results for the experimental measure. For the control measure in this study, the pre-post/then design produced the most valid results. Across both measures, the post/then design produced the least valid results.

Full textAbstract:
Background: Response bias can distort treatment effect estimates and inferences in clinical trials. Although prevention, quantification, and adjustments have been developed, current methods are not applicable when subject-level reliability is used as the measure of response bias. Thus, the objective of the current study is to develop, test, and recommend a series of bias correction strategies for use in these cases. Methods: Monte Carlo simulation and logistic regression modeling were used to develop the strategies, examining the collective impact of sample size (N), effect size (ES), reliability distribution, and response style on estimating the treatment effect size in a series of hypothetical clinical trials. The strategies included a linear (LW), quadratic (QW), or cubic weight (CW) applied to the subject-level reliability; a reliability threshold (%); or a combination of the two (W-%). Bias and percent relative root mean square error (RRMSE (%)) were calculated for each treatment effect estimate and RRMSE (%) was compared to inform the bias correction recommendations. Results: The following recommendations are made for each N and ES combination: N=200/ES=small: no adjustment, N=200/ES=medium: 40%-LW, N=200/ES=large: 40%-QW, N=2000/ES=small: 40%-LW, N=2000/ES=medium: 55%-CW, N=2000/ES=large: 75%-CW, N=20000/ES=small: 70%-CW, N=20000/ES=medium: 85%-CW, N=20000/ES=large: 95%-CW. Conclusion: Employing these bias correction strategies in clinical trials where subject-level reliability can be calculated will decrease error and increase accuracy of estimates and validity of inferences.

Full textAbstract:
The research in this thesis has been undertaken to develop statistical tools for monitoring adverse events in hospitals that adjust for varying patient risk. The studies involved a detailed literature review of risk adjustment scores for patient mortality following cardiac surgery, comparison of institutional performance, the performance of risk adjusted CUSUM schemes for varying risk profiles of the populations being monitored, the effects of uncertainty in the estimates of expected probabilities of mortality on performance of risk adjusted CUSUM schemes, and the instability of the estimated average run lengths of risk adjusted CUSUM schemes found using the Markov chain approach. The literature review of cardiac surgical risk found that the number of risk factors in a risk model and its discriminating ability were independent, the risk factors could be classified into their "dimensions of risk", and a risk score could not be generalized to populations remote from its developmental database if accurate predictions of patients' probabilities of mortality were required. The conclusions were that an institution could use an "off the shelf" risk score, provided it was recalibrated, or it could construct a customized risk score with risk factors that provide at least one measure for each dimension of risk. The use of report cards to publish adverse outcomes as a tool for quality improvement has been criticized in the medical literature. An analysis of the report cards for cardiac surgery in New York State showed that the institutions' outcome rates appeared overdispersed compared to the model used to construct confidence intervals, and the uncertainty associated with the estimation of institutions' out come rates could be mitigated with trend analysis. A second analysis of the mortality of patients admitted to coronary care units demonstrated the use of notched box plots, fixed and random effect models, and risk adjusted CUSUM schemes as tools to identify outlying hospitals. An important finding from the literature review was that the primary reason for publication of outcomes is to ensure that health care institutions are accountable for the services they provide. A detailed review of the risk adjusted CUSUM scheme was undertaken and the use of average run lengths (ARLs) to assess the scheme, as the risk profile of the population being monitored changes, was justified. The ARLs for in-control and out-of-control processes were found to increase markedly as the average outcome rate of the patient population decreased towards zero. A modification of the risk adjusted CUSUM scheme, where the step size for in-control to out-of-control outcome probabilities were constrained to no less than 0.05, was proposed. The ARLs of this "minimum effect" CUSUM scheme were found to be stable. The previous assessment of the risk adjusted CUSUM scheme assumed that the predicted probability of a patient's mortality is known. A study of its performance, where the estimates of the expected probability of patient mortality were uncertain, showed that uncertainty at the patient level did not affect the performance of the CUSUM schemes, provided that the risk score was well calibrated. Uncertainty in the calibration of the risk model appeared to cause considerable variation in the ARL performance measures. The ARLs of the risk adjusted CUSUM schemes were approximated using simulation because the approximation method using the Markov chain property of CUSUMs, as proposed by Steiner et al. (2000), gave unstable results. The cause of the instability was the method of computing the Markov chain transition probabilities, where probability is concentrated at the midpoint of its Markov state. If probability was assumed to be uniformly distributed over each Markov state, the ARLs were stabilized, provided that the scores for the patients' risk of adverse outcomes were discrete and finite.

Full textAbstract:
Det finns nu ingen tvekan om att det är vi människor, och vårt användande av fossila bränslen, som bidrar till den förstärkta växthuseffekten. Rättvisande metoder till att mäta växthusgasutsläpp är nödvändiga för att kunna fatta framtida beslut. Vägtrafiken är en av de största källorna till utsläpp av växthusgaser och den ökar hela tiden i omfattning. Den här studien fokuserar på olika metoder som används för att uppskatta koldioxidemissioner från vägtrafiken genom att först uppskatta mängderna diesel, från ett kritiskt perspektiv. Som hjälp till detta har en alternativ metod, för att uppskatta dieselkonsumtionen från vägtrafiken i Sverige, skapats. Resultaten visar skillnader mellan olika metoders uppskattningar, några av dessa i motsättning till varandra. Studien visar att resultat från modellen HBEFA 3.1 samvarierar med statistiken över levererad diesel i Sverige men visar lägre volymer. De alternativa metoderna, som skapats för den här studien, kan förklara sänkningarna av dieselkonsumtionen år 2008-2009 men kan inte förklara sänkningarna år 1999-2000 och 2011-2012. Mera studier som undersöker skillnaderna mellan resultaten från National inventory report Sweden och statistisk information över levererade mängder diesel i Sverige, och vad som orsakar dessa, behövs.There is now no doubt about that it is humans, and our usage of fossil fuels, that contributes to the global warming. Accurate methods of measuring greenhouse gases are vital for future decision making. Road traffic is one of the major sources for greenhouse gases and it is increasing in volume. This study focus on different methods, used to estimate carbon dioxide emissions from road traffic by first estimating the quantity of diesel, from a critical point of view. For that purpose an alternative method used to estimate diesel consumption from road traffic in Sweden is created. The results show differences between methods estimates, some of them in contradiction to each other. The study shows that the results from the model HBEFA 3.1 covariate with both sources of statistics on delivered diesel in Sweden but show lower volumes. The alternative methods created in this study can explain the decrease of diesel consumption in the year 2008-2009 but can’t explain the decrease in the years 1999-2000 and 2011-2012. More studies on differences between the results in the National inventory report Sweden and statistical information on deliveries of diesel, and what is causing them, are needed.

Les polymacromonomers (PMs) sont des polymères ramifiés bien définis issus de la polymérisation de macromonomères. Les méthodes de synthèse utilisées ici (polymérisation anionique et polymérisation procédant par métathèse et ouverture de cycle) nous ont permis de travailler dans les conditions d?une polymérisation ?vivante? et d?obtenir des PMs (branches de polystyrène (PS) et tronc de polynorbornène) possédant une distribution régulière et élevée de branches. La DNPA s?est avéré idéale pour décrire de façon quantitative la conformation des PMs, en offrant la possibilité de marquer nos polymères sans altérer leur architecture grâce au marquage sélectif. Différents modèles géométriques, tels que des modèles de micelles à c?ur sphérique ou cylindrique, ont été ajustés aux facteurs de forme expérimentaux mesurés par DNPA, en solution comme en fondus. Nous avons démontré que l?architecture influence directement la conformation des PMs et leurs interactions avec le milieu environnant. Notamment, sous certaines conditions apparaît une démixtion purement entropique, due à la structure intrinsèque de PMs dans les mélanges PMs ? PS linéaire. Par ailleurs, les propriétés mécaniques et le comportement dynamique des PMs sont fortement modifiés par la structure ramifiée des PMs. Nous avons mené une étude en rhéologie oscillatoire et comparé la réponse viscoélastique des PMs à celle du PS linéaire. Afin d?établir de façon précise la dynamique de relaxation des PMs, des films étirés puis relaxés ont été étudiés par DNPA. L?interprétation des résultats obtenus est complexe et s?est faite à l?aide d?un modèle de micelle modifié (combinant un c?ur ellipsoïdal et des branches modélisées par le modèle de réseau fantôme).

Context: Medical management for head and neck cancer (HNC) often includes neck dissection surgery, a side effect of which is shoulder dysfunction. There is no consensus for which patient-reported outcome measure (PRO) is most appropriate to quantify shoulder dysfunction in this population.
Objective: The aims of this research study were to: (1) use Rasch methodologies to assess construct validity and overall appropriateness of test score interpretation of Disability of the Arm, Shoulder and Hand (DASH), QuickDASH, Shoulder Pain and Disability Index (SPADI) and Neck Dissection Impairment Index (NDII) in the HNC population; (2) determine appropriateness of use of University of Washington Quality of Life (UW-QoL) shoulder subscale as a screening tool for shoulder impairment; (3) recommend a new PRO, or combination of PROs, that more accurately portrays the construct of shoulder dysfunction in the HNC population.
Design: One hundred and eight-two individuals who had received a neck dissection procedure within the past 2 weeks to 18 months completed the PROs. Rasch methodologies were utilized to address the primary aim of the study through consideration of scale dimensionality [principal components analysis, item and person fit, differential item functioning (DIF)], scale hierarchy (gaps/redundancies, floor/ceiling effects, coverage of ability levels), response scale structure, and reliability (person and item reliability and separation statistics). The secondary aim was addressed through correlational analysis of the UW-QoL (shoulder subscale), DASH, QuickDASH, SPADI and NDII.
Results: The DASH did not meet criteria for unidimensionality, and was deemed inappropriate for utilization in this sample. The QuickDASH, SPADI and NDII were all determined to be unidimensional. All scales had varying issues with person and item misfit, DIF, coverage of ability levels, gaps/redundancies, and optimal rating scale requirements. The NDII meets most requirements. All measures were found to meet thresholds for person and item separation and reliability statistics. The third aim of this study was not addressed because the NDII was determined to be appropriate for this population.
Conclusions: Rasch analysis indicates the NDII is the most appropriate measure studied for this population. The QuickDASH and SPADI are recommended with reservation. The DASH and the UW-QoL (shoulder subscale) are not recommended.

Full textAbstract:
La majorité des enfants apprennent rapidement leur langue maternelle, mais la trajectoire de leur acquisition varie d'un enfant à l'autre. C'est le cas par exemple pour la vitesse d'acquisition du vocabulaire, mais aussi pour certaines capacités précoces de perception de la parole. Des travaux menés en psycholinguistique ces deux dernières décennies ont commencé à étudier ces différences individuelles, cherchant d'une part à évaluer les facteurs qui prédisent ces différences, et d'autre part à comprendre comment ces différences impactent l'acquisition ultérieure du langage, notamment du vocabulaire. Ces études ont porté essentiellement sur la deuxième année de vie. L'objectif de cette thèse est de poursuivre ce travail dans le cadre de la première année. Il s'agit de mieux caractériser la variabilité individuelle dans trois capacités de traitement précoce, de préciser certains prédicteurs de ces capacités, et d'évaluer l'impact de la variabilité individuelle sur le vocabulaire à 12 mois. Les capacités qui nous ont intéressées sont : (1) le traitement audiovisuel de la parole à 4 et 8 mois, et plus spécifiquement l'attention relative portée par les enfants aux yeux et à la bouche d'un visage qui parle ; (2) la segmentation de formes sonores de mots d'un flux continu de parole sur la base de probabilités de transition entre les syllabes à 8 mois ; et (3) la reconnaissance de formes sonores de mots familiers à 12 mois. Les prédicteurs que nous avons évalués sont liés à la quantité d'input parental et aux capacités de production précoce des nourrissons. Pour cela, des enregistrements d'une journée complète réalisés dans l'environnement naturel des enfants ont été collectés à 4, 8 et 12 mois à l'aide d'un enregistreur porté par les enfants. Trois mesures quantitatives en ont été extraites : (1) le nombre de mots entendus par les nourrissons, (2) le nombre de tour de parole entre un parent et son enfant et (3) le nombre de vocalisations des nourrissons. De plus, une mesure qualitative de (4) babillage (inventaire des sons produits) a été prise aux âges de 4 et 8 mois grâce à des questionnaires parentaux. Concernant les liens entre input et capacités précoces, les résultats montrent que plus d'input parental à 4 mois est lié à un meilleur traitement auditif (segmentation de la parole à 8 mois et reconnaissance de formes sonores des mots à 12 mois) mais non au traitement audiovisuel de la parole. De plus, plus d'input parental à 8 mois est lié à plus de vocabulaire en compréhension à 12 mois. La quantité de tours de parole n'est pas liée aux capacités explorées, mais plus de tours de parole est lié à plus de vocabulaire en production à 12 mois. Concernant les liens entre production et capacités précoces, la quantité de vocalisations ne semble jouer qu'un rôle mineur dans les capacités précoces (restreinte au traitement audiovisuel de la parole) et n'est pas liée au vocabulaire à 12 mois. Par contre, un répertoire de babillage plus riche à 8 mois est lié au traitement auditif (meilleure segmentation de la parole) et audiovisuel (moins d'intérêt pour la bouche) de la parole au même âge et, dans une moindre mesure, aux capacités de traitement des mots à 12 mois. Un babillage plus élaboré à 4 et 8 mois est également lié à plus de vocabulaire en production à 12 mois. Enfin, concernant les prédicteurs du vocabulaire précoce, les résultats montrent que les enfants qui regardent le plus la bouche et qui ont de meilleures capacités de segmentation à 8 mois ont plus de vocabulaire en production à 12 mois. Mis ensemble, nos résultats permettent de mettre en avant qu'il existe des liens très précoces entre la quantité d'input parental, le traitement de la parole et le vocabulaire. Ces résultats soulignent également l'importance d'explorer le développement des productions précoces des enfants en lien avec le traitement de la parole et l'acquisition du vocabulaire au cours de la première année de vieThe majority of infants acquire their native language relatively fast, yet the trajectory of their acquisition varies from one child to another. This is the case for example for the rate of vocabulary growth but also for some early speech perception abilities. Research studies conducted in psycholinguistics over the last two decades started to explore these individual differences, seeking to specify the factors that predict these differences on the one hand, and to further understand how these differences impact later language acquisition, including vocabulary, on the other hand. These studies focused mainly on the second year of life. The aim of this thesis is to complement this research, focusing on the first year of life. It aims to better characterize individual variability in three early speech processing abilities, to specify some of the predictors of these abilities, and to assess the impact of individual variability on vocabulary acquisition at 12 months. The speech processing abilities we investigated are: (1) audiovisual speech processing at 4 and 8 months, and more specifically infants' relative attention towards the eyes or the mouth of a talking face; (2) word form segmentation from a continuous speech stream, based on transitional probabilities between syllables at 8 months; and (3) familiar word form recognition at 12 months. The predictors that have been investigated are related to the quantity of parental speech input and to infants' early production skills. To this end, daylong recordings were collected longitudinally in infants' natural environment at 4, 8 and 12 months of age, using a device wore by the infants at home. Three quantitative measures were extracted from these audio recordings: (1) the number of words heard by the infants, (2) the number of conversational turns between a parent and his child and (3) the number of infants' vocalizations. Moreover, a qualitative measure of (4) babbling (inventory of produced sounds) was collected at 4 and 8 months of age through parental questionnaires. Regarding the links between input and early abilities, the results show that more parental input at 4 months is related to better auditory speech processing skills (word segmentation at 8 months and word form recognition at 12 months) but not to audiovisual speech processing. In addition, more parental input at 8 months is related to more receptive vocabulary at 12 months. Furthermore, the quantity of conversational turns is not linked to the abilities investigated here, but more conversational turns is linked to more expressive vocabulary at 12 months. Regarding the links between production and early abilities, the amount of vocalizations appears to only play a minor role in early abilities (limited to audiovisual speech processing) and is not linked to vocabulary at 12 months. However, a richer babbling repertoire at 8 months is linked to auditory (better segmentation skills) and audiovisual speech processing skills (less interest in the mouth) at the concurrent age and, to a lesser extent, to word processing abilities at 12 months. A more complex babbling at 4 and 8 months is linked to more vocabulary in production at 12 months. Lastly, regarding the predictors of early vocabulary, the results show that infants who look the most towards the mouth and who have better speech segmentation skills at 8 months have more vocabulary in production at 12 months. Taken together, our results help us highlight the existence of very early links between the amount of parental input, speech processing skills and vocabulary. These results also emphasize the importance of investigating infants' early production skills together with speech processing skills and vocabulary acquisition during the first year of life

Full textAbstract:
The problem this study addressed is the relationship between Clery Act crime data and student recruitment at private colleges and universities. For this quantitative study, I used secondary data from the Department of Education and the Delta Cost Project (2013) to conduct ordinary least squares regression analyses to determine the predictive ability of institutional characteristics, specifically the total number of crime incidents reported in compliance with the Clery Act, on the variance in number of applications and applicant yield rate at private four-year institutions in the United States. Findings showed that the total number of reported incidents was a significant positive predictor of the total number of applications. Conversely, findings also showed that the total number of incidents had a significant negative impact on institutional yield rates. An implication of this study is that although crime statistics required by the Clery Act may not serve as variables used in the student application process, they are part of numerous variables used in the student's decision to enroll at a particular school. The findings highlight the importance of prioritizing and investing in safety and security measures designed to reduce rates of crime; especially for private, enrollment-driven institutions of higher education.

Can change in citation patterns among journals be used as an indicator of structural change in the organization of the sciences? Aggregated journal-journal citations for 1999 are compared with similar data in the Journal Citation Reports 1998 of the Science Citation Index. In addition to indicating local change, probabilistic entropy measures enable us to analyze changes in distributions at different levels of aggregation. The results of various statistics are discussed and compared by elaborating the journal-journal mappings. The relevance of this indicator for science and technology policies is further specified.

Full textAbstract:
Indiana University-Purdue University Indianapolis (IUPUI)Ecological momentary assessment (EMA) has been asserted by proponents of the technique as being superior to standard paper-and-pencil measurements in terms of the reliability and validity of the information obtained; however, this claim has not yet been fully evaluated in the literature. Accordingly, the purpose of this study was to evaluate one aspect of this assertion by comparing the utility of EMA and retrospective measures of depressive symptoms in predicting health-relevant biological and behavioral outcomes. It was hypothesized that (1) the EMA measure will have better predictive utility when examining objective sleep quality (a biological outcome), and that (2) the retrospective measure will have better predictive utility when examining blood donation intention (a behavioral outcome). Ninety-six undergraduate females participated in this 2-week study. Depressive symptoms were measured momentarily and retrospectively using the Center for Epidemiological Studies-Depression Scale (CES-D). The biological outcome was assessed by actigraphy, whereas the behavioral outcome was measured via a self-report questionnaire. Unfortunately, it was not possible to fully test these hypotheses due to the failure to observe relationships between the predictor variables and the outcomes. The reported results, although limited, did not provide support for the hypotheses. Supplemental analyses revealed a moderate to high amount of shared variance between the EMA and retrospective measures, a similar extent of random error in both measures, and potentially a greater degree of systematic error in the retrospective measure. Due to the paucity of literature examining the claim of superior reliability and validity of EMA versus retrospective measures, as well as the failure of the current study to evaluate this assertion sufficiently, it appears that this claim remains unfounded. Therefore, suggestions for future research are provided.

Thesis (Ph. D. (Science)) -- University of Limpopo, 2015The objectives of the study were to examine the demographic profile and causes of death of people dying in a hospital and community; and to determine mortality rates, specifically age- and gender-specific mortality rates in a community. The study also compared causes of death assigned to hospital records with causes of death obtained from verbal autopsy reports. Methodology The data used in this thesis were collected in two phases. The first phase involved a retrospective review of all deaths that occurred in the Pietersburg/Mankweng Hospital Complex from 1st January, 2011 to 31st December, 2012. The second phase involved a community-based study using a verbal autopsyto determine cause of death in Dikgale HDSS for the same period. Results A total of 5402 deaths were reported in the hospital and 625 in the community. The majority of deaths in the hospital involved adults in the 15 to 49 year old age group, while in the community more deaths were recorded amongst adults aged 15 to 49 years of age and those in the 65+ year old age group. There were more male deaths in the hospital, while in the community a higher proportion of deaths occurred amongst females. v In children less than1 year old, the cause of death in the hospital was predominantly due to perinatal conditions, particularly preterm birth, low birth weight and birth asphyxia; while in the community, of the 5 deaths in this age group, infectious diseases were recorded as the main cause of death. Amongst children in the 1 to 4 year old age groups causes of hospital deaths were dominated by infectious diseases, injuries and malnutrition; while in the community infectious diseases were the main cause of death. Stillbirths were noted in the hospital with a stillbirth rate of 29.1/1000 deliveries. In the community no stillbirths were reported. More than half of the stillbirths were caused by unexplained intrauterine foetal causes followed by maternal hypertension in pregnancy and placenta abruption. For adults in the 15 to 49 year old age groups infectious diseases, such as HIV/AIDS and tuberculosis, were the leading causes of death in both the hospital and in the community. The proportion of deaths due to HIV/AIDS and tuberculosis was significantly greater in the community than in the hospital. Amongst adults in the 50+year old age group non-communicable diseases, particularly cardiovascular diseases and cancers were the most common causes of death. In this age group, the hospital recorded more cancer deaths than did the community; while the community recorded more cardiovascular deaths than did the hospital. vi The overall mortality rate in the community was 8.4 deaths per 1000 person-year, with more deaths occurring amongst males (8.9 deaths per 1000 person-year). The mortality rate was high amongst adults in the 65+ year old age group (48.9 deaths per 1000 person-year). When comparing cause-specific mortality between hospital cause of death notification forms and cause of death determined by verbal autopsy reviews, the same top five underlying causes of death were observed, namely: cardiovascular diseases, infectious diseases, diabetes mellitus, malignant neoplasms and respiratory infections. The agreement between causes of death reported on cause of death notification forms and cause of death as a result of a verbal autopsywas 48%. For individual causes, agreement of more than 80% was achieved between cause of death recorded on cause of death notification forms and from verbal autopsy reviews for respiratory infections, diabetes, malignancies and injuries. Infectious diseases (68.5%) and cardiovascular diseases (74.1%) achieved the lowest agreement. In other words, in only 68.5% and 74.1% respectively was the cause of death as recorded on the “cause of death notification” forms the same as the cause of death when reviewed verbally. Furthermore, 13 deaths were recorded as being due to cardiovascular diseases on the “cause of death notification” forms, however, in only 5 of these cases was the cause of death recorded as the same in the verbal autopsy report. In 21 cases cause of death was attributed to infectious diseases on the cause of death notification form, vii while in only 13 of these cases was the cause of death similarly ascribed after verbal autopsy review. Conclusion This study showed that the verbal autopsy instrument has the potential to identify causes of death in a population where deaths occur outside of health facilities. Procedures for death certification and coding of underlying causes of death need to be streamlined in order to improve the reliability of registration data. This will be achieved if medical students and trainee specialists are trained in the completion of cause of death notification forms. Foetal autopsies should be introduced at tertiary hospitals to determine the causes of stillbirths.Antenatal care education for pregnant women should be encouraged because the level of antenatal care has an influence on the health of mothers and their newborns. The government should continue to focus on improving the socio-economic status of the population, while adequate foetal monitoring by health workers may reduce neonatal deaths resulting from preterm births, low birth weight and birth asphyxia. Innovative injury prevention strategies, interventions to control infectious diseases, cancer screening and lifestyle program may reduce adult mortality.

Full textAbstract:
Existing methods to systematically characterize sequence-intrinsic activity of promoters are limited by relatively low throughput and the length of sequences that could be tested. Here we present Survey of Regulatory Elements (SuRE), a method to assay more than a billion DNA fragments in parallel for their ability to drive transcription autonomously. In SuRE, a plasmid library is constructed of random genomic fragments upstream of a barcode and decoded by paired-end sequencing. This library is transfected into cells and transcribed barcodes are quantified in the RNA by high-throughput sequencing. By computationally analyzing the resulting data using generalized linear models, we succeed in delineating subregions within promoters that are relevant for their activity on a genomic scale, and making accurate predictions of expression levels that can be used to inform minimal promoter reporter construct design. We also show how our approach can be extended to analyze the differential impact of single-nucleotide polymorphisms (SNPs) on gene expression.

Johannesburg, 2012Background: There is a heavy reliance on registrars for afterhours CT reporting with a resultant unavoidable error rate. This study was done to determine this error rate. Material and Methods: A 2 month prospective study was undertaken. Provisional CT reports issued by the registrar on call were reviewed information relating to the errors made during the call were recorded and analyzed. Results: 1477 CT scans were performed with an overall error rate of 17.1%. A significant difference was found between trauma (15.8%) compared to non-trauma scans (19.2%). The difference between emergency scans (16.9%) and elective scans (22.6%) was not significant. Abdominopelvic scans elicited the highest error rate (33.9%). Increasing workload resulted in a significant increase in error rate. Missed findings were the most frequent errors (57.3%). Error rate decreased with increasing year of training.
