Cette thèse expose les résultats d’une recherche praticienne inédite menée pendant plusieurs décennies auprès de psychologues du travail exerçant une fonction de sélection-orientation, dans un organisme public, auprès d’une population d’adultes dans des conditions professionnelles et techniques strictement identiques. Toute évaluation d’un potentiel intellectuel réalisée selon la méthode des tests psychométriques n’est pas réductible aux résultats obtenus. Ceux-ci doivent nécessairement être interprétés par le psychologue pratiquant l’examen. C’est une exigence méthodologique inhérente à la pratique des tests. Dans cette phase d’interprétation se trouve à l’œuvre un processus décisionnel que l’on peut supposer d’autant plus opaque qu’il est sous l’emprise d’un pouvoir discrétionnaire : celui du praticien en charge de l’évaluation. Cette nécessité du processus d’interprétation d’une performance obtenue à un test pourrait être de nature à contrarier, voire contredire, les règles de rigueur et de stricte objectivité de la méthode expérimentale à laquelle se référent les tests psychométriques. Il est donc légitime d’avancer l’hypothèse que la conclusion émise par l’évaluateur ne peut échapper pour une part à sa subjectivité. Ne résulte-t-il pas alors un hiatus induisant une rupture épistémologique ? L’ampleur des données recueillies à partir de près de 40.000 dossiers psychotechniques permet une étude différentielle de la « production » de ces psychologues du travail. Par une approche statistique, nous avons analysé la variabilité des interprétations et des décisions associées au sein de l’échantillon des évaluateurs. Il ressort des analyses des données qu’est confirmée l’hypothèse initiale d’un défaut, intrinsèquement lié à leurs mise en pratique, des techniques de tests psychométriques pour parvenir à un niveau d’objectivité satisfaisant permettant d’appuyer l’orientation des sujets candidats. Ces travaux de recherche qui réunissent en définitive les caractéristiques et les conditions d’une approche docimologique apportent une preuve supplémentaire que ces techniques d’évaluation ne sauraient prétendre au niveau d’objectivité scientifique dont elles se réclament. Ils mettent en évidence l’empreinte subjective liée à toute évaluation à base de tests psychométriques conduisant à s’interroger sur la pertinence des discours habituellement tenus sur l’utilité sociale de celle-ci. / This thesis presents the results of unprecedented practitioner research conducted for several decades with work psychologists holding a position of selection and work orientation, in a public organization, in a population of adults in strictly identical professional and technical conditions.Any assessment of intellectual potential realized according to psychometric testing method is not reducible to the results obtained. These must necessarily be interpreted by the psychologist doing examination. This is an inherent methodological requirement to conducting tests. In this phase of interpretation there is a decision-making process that we can assume even more opaque for it is under the influence of discretion: that of a practitioner in charge of the evaluation.This necessity of the interpretation process of a test performance might be likely to impede or even contradict the rules of rigor and of strict objectivity of the experimental method to which the psychometric tests refer. It is therefore legitimate to advance the hypothesis that the conclusion issued by the evaluator can not avoid in part his subjectivity. Does not it follow then a hiatus inducing an epistemological break?The extent of data collected from nearly 40,000 psychotechnical records allows a different study of the "production" of these work psychologists. With a statistical approach, we have analyzed the variability of interpretations and associated decisions within the sample of evaluators. It appears from the data analysis that was confirmed the initial assumption of a flaw, intrinsically bound to their implementation, psychometric testing techniques to achieve a satisfactory level of objectivity that will support the orientation of candidates.This research project that ultimately brings together the characteristics and conditions of a docimological approach provides an additional evidence that these assessment techniques can not assert the level of scientific objectivity which they claim. They highlight the subjective mark of any assessment based on psychometric tests leading to wonder about a relevance of position usually held on the social utility of assessment.

New application versions may contain source code changes that decrease the application’s performance. To ensure sufficient performance, it is necessary to identify these code changes. Peass is a performance analysis tool using performance measurements of unit tests to achieve that goal for Java applications. However, it can only be utilized for Java applications that are built using the tools Apache Maven or Gradle. This thesis provides a plugin for Peass that enables it to analyze applications built with Apache Ant. Peass utilizes the frameworks Kieker and KoPeMe to record the execution traces and measure the response times of unit tests. This results in the following tasks for the Peass-Ant plugin: (1) Add Kieker and KoPeMe as dependencies and (2) Execute transformed unit tests. For the first task, our plugin programmatically resolves the transitive dependencies of Kieker and KoPeMe and modifies the XML buildfiles of the application under test. For the second task, the plugin orchestrates the process that surrounds test execution—implementing performance optimizations for the analysis of applications with large codebases—and executes specific Ant commands that prepare and start test execution. To make our plugin work, we additionally improved Peass and Kieker. Therefore, we implemented three enhancements and identified twelve bugs. We evaluated the Peass-Ant plugin by conducting a case study on 200 commits of the open-source project Apache Tomcat. We detected 14 commits with 57 unit tests that contain performance changes. Our subsequent root cause analysis identified nine source code changes that we assigned to three clusters of source code changes known to cause performance changes.:1. Introduction 1.1.

Future Work / Neue Versionen einer Applikation können Quelltextänderungen enthalten, die die Performance der Applikation verschlechtern. Um eine ausreichende Performance sicherzustellen, ist es notwendig, diese Quelltextänderungen zu identifizieren. Peass ist ein Performance-Analyse-Tool, das die Performance von Unit-Tests misst, um dieses Ziel für Java-Applikationen zu erreichen. Allerdings kann es nur für Java-Applikationen verwendet werden, die eines der Build-Tools Apache Maven oder Gradle nutzen. In dieser Arbeit wird ein Plugin für Peass entwickelt, das es ermöglicht, mit Peass Applikationen zu analysieren, die das Build-Tool Apache Ant nutzen. Peass verwendet die Frameworks Kieker und KoPeMe, um Ausführungs-Traces von Unit-Tests aufzuzeichnen und Antwortzeiten von Unit-Tests zu messen. Daraus resultieren folgende Aufgaben für das Peass-Ant-Plugin: (1) Kieker und KoPeMe als Abhängigkeiten hinzufügen und (2) Transformierte Unit-Tests ausführen. Für die erste Aufgabe löst das Plugin programmbasiert die transitiven Abhängigkeiten von Kieker und KoPeMe auf und modifiziert die XML-Build-Dateien der zu testenden Applikation. Für die zweite Aufgabe steuert das Plugin den Prozess, der die Testausführung umgibt, und führt spezielle Ant-Kommandos aus, die die Testausführung vorbereiten und starten. Dabei implementiert es Performanceoptimierungen, um auch Applikationen mit einer großen Codebasis analysieren zu können. Um die Lauffähigkeit des Plugins sicherzustellen, wurden zusätzlich Verbesserungen an Peass und Kieker vorgenommen. Dabei wurden drei Erweiterungen implementiert und zwölf Bugs identifiziert. Um das Peass-Ant-Plugin zu bewerten, wurde eine Fallstudie mit 200 Commits des Open-Source-Projekts Apache Tomcat durchgeführt. Dabei wurden 14 Commits mit 57 Unit-Tests erkannt, die Performanceänderungen enthalten. Unsere anschließende Ursachenanalyse identifizierte neun verursachende Quelltextänderungen. Diese wurden drei Clustern von Quelltextänderungen zugeordnet, von denen bekannt ist, dass sie eine Veränderung der Performance verursachen.:1. Introduction 1.1. Motivation 1.2. Objectives 1.3.

Title: Assessment of motor performance and body holding in young school-age children Objectives: The aim of this thesis is the assessment of motor performance, body holding and basic information concerning movement activity in young school-age children and to reveal any possible interrelations between these data. Hypothesis: 1. The volume of movement load in young school-age children affects their motor performance and body holding. 2. Motor performance evaluated by a modification of the UNIFITTEST has a significant correlation with body holding in young school age children. Methods: In order to determine the level of motor performance of the children, I used a modification of the UNIFITTEST (Měkota et al., 2002), while I also evaluated their basic somatic parameters. Their body holding was evaluated according to Mathias (Hošková and Matoušová 2007), Jaroš and Lomníček (Hošková and Matoušová 2007) and Adams's Test (Haladová and Nechvátalová 2005). Information about the frequency of the children's sports activities and their lifestyle, I collected with the form of a short survey. The research group consists of 19 boys and 11 girls with an average age of 9 years old (age range 8-11 years - by 1.1.2018), mean body height of 1.4 m (σ=8,2 cm) and mean body weight of 36.5 kg (σ=9,1 kg).

Les technologies de communication et les services web sont devenus disponibles dans notre vie numérique, les réseaux informatiques continuent de croître et de nouveaux protocoles de communication sont constamment définis et développés. Par la suite, la standardisation et la normalisation des protocoles sont dispensables pour permettre aux différents systèmes de dialoguer. Bien que ces normes peuvent être formellement vérifiés, les développeurs peuvent produire des erreurs conduisant à des implémentations défectueuses. C'est la raison pour laquelle leur mise en œuvre doit être strictement examinée. Cependant, la plupart des approches de tests actuels exigent une stimulation de l’exécution dans le cadre des tests (IUT). Si le système ne peut être consulté ou interrompu, l'IUT ne sera pas en mesure d'être testé. En outre, la plupart des travaux existants sont basées sur des modèles formels et très peu de travaux s'intéressent à la formalisation des exigences de performance. Pour résoudre ces problèmes, nous avons proposé une approche de test basé sur la logique "Horn" afin de tester passivement la conformité et la performance des protocoles. Dans notre approche, les exigences peuvent être formalisées avec précision. Ces exigences formelles sont également testées par des millions de messages collectés à partir des communicants réels. Les résultats satisfaisants des expériences effectuées ont prouvé le bon fonctionnement et l'efficacité de notre approche. Aussi pour satisfaire les besoins croissants de tests distribués en temps réel, nous avons également proposé un cadre de tests distribués et un cadre de tests en ligne et nous avons mis en œuvre notre plateforme dans un environnement réel à petite échelle avec succès / While today’s communications are essential and a huge set of services is available online, computer networks continue to grow and novel communication protocols are continuously being defined and developed. De facto, protocol standards are required to allow different systems to interwork. Though these standards can be formally verified, the developers may produce some errors leading to faulty implementations. That is the reason why their implementations must be strictly tested. However, most current testing approaches require a stimulation of the implementation under tests (IUT). If the system cannot be accessed or interrupted, the IUT will not be able to be tested. Besides, most of the existing works are based on formal models and quite few works study formalizing performance requirements. To solve these issues, we proposed a novel logic-based testing approach to test the protocol conformance and performance passively. In our approach, conformance and performance requirements can be accurately formalized using the Horn-Logic based syntax and semantics. These formalized requirements are also tested through millions of messages collected from real communicating environments. The satisfying results returned from the experiments proved the functionality and efficiency of our approach. Also for satisfying the increasing needs in real-time distributed testing, we also proposed a distributed testing framework and an online testing framework, and performed the frameworks in a real small scale environment. The preliminary results are obtained with success. And also, applying our approach under billions of messages and optimizing the algorithm will be our future works
