In einer Reihe neuerer epidemiologischer Studien wurde ein Zuwachs in der Prävalenz der Major Depression in jüngeren Geburtskohorten und ein sinkendes Ersterkrankungsalter dieser Störung beobachtet (Cross-National Collaborative Group, 1992; Klerman & Weissman, 1989). Gleichzeitig wurden bei älteren Personen auffallend niedriege Depressionsraten gefunden. Der vorliegende Beitrag gibt einen Überblick über die diesen Beobachtungen zugrundeliegenden Studien. Die Validität der Befunde und ihre Bedeutsamkeit für die Ätiologie der Major Depression sowie mögliche Alternativerklärungen der zeitlichen Effekte werden diskutiert. Während der Befund eines Zuwachses depressiver Störungen in jüngeren Geburtskohorten empirisch gut belegt ist, sind die niedrigen Depressionsraten bei älteren Personen zumindest teilweise auf einen Artefakt der Forschungsmethodologie zurückzuführen. / The findings of a number of recent major epidemiological studies in different countries document an increase in the cumulative lifetime prevalence estimates of major depression with each successively younger birth cohort and a decrease in the age of onset of this disorder (Cross-National Collaborative Group, 1992; Klerman & Weissman, 1989). At the same time comparably low depression estimates are found for the elderly. The paper presents an overview of the major studies conducted in this area in recent years. The validity of the findings, their significance for the aetiology of Major Depression and possible alternative explanations for the temporal trends are discussed. While much valid empirical evidence confirms the increase of Major Depression in recent birth cohorts, the low prevalence estimates in the elderly seen to represent at least in part an artifact of the research methodology.

This thesis is an attempt to gather and discuss the archaeological and osteological results that has been found in stone ship settings on Gotland. The bone material from five ship settings, one stone setting and a cairn from the bronze age complex at Rannarve in Klinte parish on Gotland has been osteologically analysed during this study to further expand the osteological results that are available from ship settings on Gotland and try to interpret this site. The aim is to try to find what artefacts and bone patterns that can be distinguished from the material found within ship settings. What patterns can be seen in artefacts, age, sex and burial contexts that has been found in ship settings? What are the most common patterns? / Den här uppsatsen är ett försök till att samla och diskutera vilka arkeologiska och osteologiska resultat som påträffats i skeppssättningar på Gotland. Benmaterialet från fem skeppssättningar, en stensättning och ett röse i Rannarve i Klinte socken på Gotland har analyserats osteologiskt för att utöka de osteologiska resultaten som finns tillgängliga för skeppssättningar på Gotland samt för att försöka tolka platsen. Målet är att försöka se vilka föremål och benmönster som går att urskilja från materialet och se vilka mönster som finns mellan fynd, ålder, kön och gravkontext i de olika skeppssättningarna, samt vilka mönster som är de mest vanliga.

The aim of this study is to present the architectural and organizational characteristics of Burgaz houses by taking into consideration a number of internal and external factors such as economical, social and environmental that influenced the house plan and its utilization in 4th century BC. To discuss the place of Burgaz house within the ancient Greek domestic context, the architectural, structural, and functional characteristics of houses are investigated and compared to contemporary examples, such as Olynthus and Haleis from Mainland Greece, as well as Kolophon and Klazomenai from Western Anatolia.

I explore how recreational canoeists develop sense of place developed and ecological identity through experience. The intersection between artefact and narrative is the entry-point of exploration of understandings of how recreational canoeists learn through experiences. There are three structural elements. A factional narrative arc of a canoe trip frames the work. Fragments of collective narratives: weave into this story and add richness and depth of experience. Participants’ interwoven narratives form the second element of this work. Finally, footnotes underpin this text to explain and support the research. They emerge to reflect the complexity of telling, and understanding, experience. This is a story of stories. This is a story of a trip that never happened. It holds real participants’ narratives based in lived experiences that shape this story. Narratives emerge between artefact and experience, between experience and ecological identity, between ecological identity and place, and between place and story.

The main aim of this study is to define the cooking activity spaces in Burgaz at 4th Century B.C. by carrying out statistical analysis of artefacts come from floor levels. In this study the distribution of artefacts and the associations of these distributions with architectural remains are examined rather than architectural features. In order to defining cooking activity spaces, the spatial distribution of cooking wares and utilities were taken into consideration. The distributions of cooking wares were tried to associate with ashy areas that can be related to cooking activities. In this study, the spatial analysis of archaeological artefacts assemblages that found in four well preserved houses from NE Sector revealed during the excavations of Burgaz (1993-2003) was carried out and the space usage, especially cooking spaces, were identified in these houses.

Depuis la fin du 20ème siècle, l'imagerie médicale s'est fortement développée et représente aujourd'hui un moyen incontournable pour le diagnostic médical. Dans le domaine de la radiologie par rayons X, de nouveaux détecteurs numériques remplacent progressivement les anciennes techniques à film et permettent d'obtenir des images de meilleure qualité. Cette thèse, préparée en collaboration entre l'entreprise Trixell, constructeur de détecteurs plats numériques pour la radiographie, et le laboratoire Gipsa-Lab, s'inscrit dans le cadre général du contrôle qualité de ces détecteurs par analyse d'images. Les applications biomédicales mettant en jeu ces appareils, sont généralement particulièrement sensibles, et le principe de « zéro défaut » est de mise quant à la qualité des produits. Malgré les différents traitements, certains défauts peuvent être présents dans les images. Cette thèse est axée sur le développement de modèles de mesure de la visibilité des défauts, en cohérence avec l'observation d'un humain. Deux approches complémentaires sont développées : la première approche basée sur des expériences psychophysiques et la seconde approche de modélisation basée sur la théorie de décision. Par rapport aux modèles de visibilité existants, notre modèle prend en compte la perception humaine et notamment les saccades et fixations oculaires dans l'analyse des images : le test de visibilité est ainsi le produit de tests de visibilité locaux, calculés aux points saillants de l'image supposés indépendants. Les résultats montrent l'intérêt de notre approche, notamment pour des détecteurs statiques. En se fondant sur les résultats et une dernière expériences d'oculométrie, cette thèse suggère en perspective la prise en compte d'autres caractéristiques comme le nombre de fixations oculaires, et leur durée. / Since the beginning of the 20th century, medical imaging has significantly been improved and represents now an essential mean for medical diagnosis. In the field of radiology, new digital detectors are gradually replacing the old film techniques allowing a better image. This thesis, prepared in collaboration between the company Trixell, manufacturer of X-ray detectors, and the laboratory Gipsa-Lab, is part of the framework of quality control of these detectors by image analysis. Biomedical applications involved by these devices are particularly sensitive, and the principle of “zero artifact” is required to ensure the quality of the product. Despite the various processings, some artifacts may be present in the images.This thesis focuses on the development of models that quantify the visibility of artifacts in concordance to human observation. Two complementary approaches are developed : the first one is based on psychophysical experiments and the second one is a modeling approach based on decision theory. In comparison to existent models, our model takes into account perception characteristics including saccades and eye fixation in image analysis : the visibility test is thus the product of local visibility tests calculated on the salient points of the image and assumed to be independent. The results show the interest of our approach, especially for static detectors. Based on the results and a final eye-tracking experiment, this thesis suggests perspectives taking into account other characteristics such as the number of eye fixations and their duration.

Företag inom fordonsindustrin sätter mer och mer press på snabba utvecklingsprocesser och ny avancerad teknik, vilket resulterar i att mindre tid allokeras åt utveckling som kräver mer och mer tid. Syftet med detta examensarbete var att ta fram, utveckla och utvärdera ett automatiskt verifieringssystem lämpat för ett företag inom fordonsindustrin med VT System som testmiljö och Jenkins som byggserver. Utifrån syftet definierades tre frågeställningar som besvarades genom att först undersöka vilka komponenter ett automatiskt verifieringssystem kan innehålla, för att sedan utveckla ett automatiskt verifieringssystem samt en tillhörande arkitektur. Slutligen utvärderades det automatiska verifieringssystemet genom ett experiment för att undersöka dess tidseffektivitet. För att uppnå detta syfte samt besvara examensarbetets frågeställningar valdes Design Science Research som metod för arbetet. Resultatet från experimentet visar på att det inte finns någon signifikant tidseffektivitetsskillnad mellan ett automatiskt verifieringssystem och ett manuellt utförande av samma uppgift. Examensarbetet belyser andra aspekter som det automatiska verifieringssystemet istället kan bidra med till verksamheten. Resultaten från arbetet bidrar till kunskapsområdena automatiska tester och helt autonoma system, detta genom att dels presentera en arkitektur för ett automatiskt verifieringssystem och dels genom resultat från tidigare nämnt experiment. / Automotive companies are increasingly investing in fast development processes and new advanced technology, resulting in less time being allocated to development that is more time consuming. The purpose of this thesis was to develop and evaluate an automatic verification system adapted for companies within the automotive industry with VT System as test environment and Jenkins as build server. Based on this purpose, three research questions were defined and then answered by first investigating which components an automatic verification system could contain. This was followed by the development of an automatic verification system and a corresponding architecture. Finally, the automatic verification system was evaluated through an experiment, with the purpose of investigating it’s time efficiency. To achieve the purpose of this thesis the method Design Science Research was used. The results from the experiment shows that there is no significant difference in time efficiency between the automatic verification system and a manual approach of the same task. The thesis highlights other aspects of the automatic verification system in which it can contribute. The result of the work contributes to different knowledge areas such as automated testing and fully automated systems, it does this by presenting an architecture for an automatic verification system and by presenting the result from the above-mentioned experiment.

The thesis deals with the historical development of applied arts and the plant motifs of decorative creation. There is also mentioned the problem of the natural geometric decorative motifs development and the difference between the functional and decorative artefact. Then there are described the sources of inspiration, which were used as basis for the practical part. Description of the practical part deals with the production of ceramic artefacts, then with the problem of colours and in the end it describes the installation of light into one of the objects, which is the decorative light.

Notre travail de recherche s’intéresse à l’usage des technologies dans les interactions professionnelles, et en particulier dans des centres d’appel. Nos analyses s’appuient sur trois champs disciplinaires que sont l’Ethnométhodologie, l’Analyse Conversationnelle et les Workplace Studies. Notre étude cherche à contribuer à la réflexion sur des interactions médiées par les technologies en milieu professionnel afin de rendre compte des pratiques émergentes des participants et comprendre l’organisation séquentielle complexe des interactions entre conseiller/opérateur et patient/client s’appuyant sur l’utilisation de ressources technologiques. La thèse s’articule en une partie introductive et trois parties analytiques. La première étudie les modifications de cadre participatif en tenant compte du dispositif technologique comme point d’ancrage de l’activité des participants. Nous avons distingué deux configurations: i) soit le dispositif est ajusté par l’opérateur ; ii) soit l’opérateur s’ajuste au dispositif. La modification du cadre participatif peut être initiée de façon verbale ou non verbale, ou par l’un ou l’autre des participants.Dans une seconde partie, nous analysons l’intégration de l’écran comme artefact interactionnel dans l’activité des participants. Nous avons remarqué qu’ils rapportent à l’oral des informations écrites sur un écran, en employant des verbes introductifs du type « il dit que », que nous retrouvons dans les travaux sur le discours rapporté à l’oral. Nous avons voulu montrer le lien entre le cours d’action dans lequel sont engagés les participants et l’émergence de ces discours rapportés où la référence aux messages écrits peut transformer les écrans et les systèmes informatiques en « agents interactionnels ». La troisième partie se focalise sur un type d’appel où un client s’adresse au service pour résoudre un problème, et après vérification par l’opératrice, elle lui notifie un état a-problématique de son compte. Nous avons remarqué que l’activité de diagnostic opérée ici par l’opératrice dépend étroitement des informations du compte client indiquées sur l’écran. Ce sont ces données qui permettent à l’opératrice d’établir le diagnostic et de notifier l’état a-problématique du compte. / Our research focuses on the use of technology in interactions at work, particularly in the context of call centres. Our analyses draw on three theoretical domains: Ethnomethodology, Conversation Analysis and Workplace Studies. Our research seeks to contribute to current investigations on interactions mediated by technology in the workplace to reflect emerging practices of participants and to understand the complex sequential organization of interactions between councillor/operator and patient/user, based on the use of technological resources.The thesis comprises an introduction part and three analytical parts. The first part examines changes in participation framework taking into account the technological device as an anchor for the participant’s activity. For this, we distinguished two different configurations: i) the device is adjusted by the operator, or ii) the operator adjusts the device. The adjustment of the participation framework may be initiated through verbal or multimodal way, or by one or the other participant.In the second part, we analyze the integration of the screen as an interactional artefact in the participant’s activity. We noticed that they report oral information’s displayed on a screen, using introductory verbs such as "he said", which we found in the studies on reported speech in spoken interactions. We wanted to show the link between the course of action in which participants are engaged and the emergence of reported speech when referring to written messages that can transform the screens and the computer systems in “interactional agents”.The third part focuses on one type of call where a user call the service to solve a problem, and after verification by the operator, she notifies a status of his account. We noticed that the diagnosis activity reported by the operator is closely related to the user’s account information shown on the screen. These are data that allow the operator to diagnose and report the non-problematic status of the account.
