Dans la première partie de la thèse, nous présentons un nouveau système permettant de produire des mouvements de caméra réalistes pour l'animation stopmotion. Le système permettra d'enrichir les logiciels d'animation 3D classiques (comme par exemple Maya et 3D Studio Max) afin de leur faire contrôler des mouvements de caméra pour la stop motion, grâce à l'utilisation d'une interface haptique. Nous décrivons le fonctionnement global du système. La première étapeconsiste à récupérer et enregistrer les données envoyées par le périphérique haptique de motion capture. Dans la seconde étape, nous réélaborons ces données par un procédé mathématique, puis les exportons vers un logiciel de 3D pour prévisualiser les mouvements de la caméra. Finalement la séquence est exécutée avec un robot de contrôle de mouvement et un appareil photo. Le système est évalué par un groupe d'étudiants du Master "Art plastiques et Création numérique" de l'Université de Valenciennes. Dans la deuxième partie, nous définissons une nouvelle classe de courbes à partir des courbes polynomiales paramétriques à hodographe pythagorien (PH) construite sur un espace algébrique-trigonométrique. Nous montrons leurs propriétés fondamentaleset leurs avantages importants par rapport à leur équivalent polynomial, grâce à l'utilisation d'un paramètre de forme. Nous introduisons une formulation complexe et nous résolvons le problème d'interpolation de Hermite.

Gerade in Großveranstaltungen geht die Interaktion zwischen Lehrenden und Lernenden häufig verloren. So genannte Classroom Response Systems (CRS) knüpfen an dieser fehlenden Aktivierung und Interaktion an, indem sie als technisches Hilfsmittel die klassischen Interaktionsformen wie Fragen oder Abstimmungen auch in Großveranstaltungen ermöglichen. Ein solches Feedbacksystem wurde mittels der myTU-App ohne kostenintensive Anschaffungen realisiert. Die Entwickler der myTU-App arbeiten stetig an der Weiterentwicklung und Verbesserung der App. Dafür ist es wichtig, sowohl die Bedürfnisse und Wünsche der Nutzer/innen, als auch die Ablehnungsgründe derer, die die App nicht nutzen, zu kennen. Aus diesem Grund wurde eine Evaluation zur myTU-App durchgeführt.

This PhD thesis investigated the role of the basal ganglia in memory and motor inhibition. Recent neuroimaging evidence suggests a supramodal network of inhibition involving the lateral prefrontal cortex. Here we examined whether this supramodal network also includes subcortical structures, such as the basal ganglia. Despite their well-established role in motor control, the basal ganglia are repeatedly activated but never interpreted during memory inhibition. We first used a series of meta-analyses to confirm the consistent involvement of the basal ganglia across studies using memory and motor inhibition tasks (including the Go/No-Go, Think/No-Think, and Stop-signal tasks), and discovered that there may be different subprocesses of inhibition. For instance, while the Go/No-Go task may require preventing a response from taking place, the Think/No-Think and Stop-signal tasks may require cancelling an emerging or ongoing response. We then conducted an fMRI study to examine how the basal ganglia interact with other putative supramodal regions (e.g., DLPFC) to achieve memory and motor inhibition during prevention and cancellation. Through dynamic causal modelling (DCM), we found that both DLPFC and basal ganglia play effective roles to achieve inhibition in the task-specific regions (hippocampus for memory inhibition; primary motor cortex (M1) for motor inhibition). Specifically, memory inhibition requires a DLPFC-basal ganglia-hippocampus pathway, whereas motor inhibition requires a basal ganglia-DLPFC-M1 pathway. We correlated DCM coupling parameters with behavioural indices to examine the relationship between network dynamics during prevention and cancellation and the successfulness of inhibition. However, due to constraints with DCM parameter estimates, caution is necessary when interpreting these results. Finally, we used diffusion weighted imaging to explore the anatomical connections supporting functions and behaviour. Unfortunately, we were unable to detect any white matter variability in relation to effective connectivity or behaviour during the prevention or cancellation processes of memory and motor inhibition at this stage. This PhD thesis provides essential INITIAL evidence that not only are the basal ganglia consistently involved in memory and motor inhibition, but these structures are effectively engaged in these tasks, achieving inhibition through task-specific pathways. We will discuss our findings, interpretations, and future directions in the relevant chapters.

A partir de uma perspectiva interpretativa, que no campo das políticas públicas está voltada à análise dos sentidos, o trabalho busca identificar e comparar os sentidos implícitos na formulação da política e também os sentidos atribuídos por seus implementadores, ou seja, os policiais da ponta da linha. Também pretende inferir em que medida a relação entre a polícia e a comunidade interfere na forma como o policial realiza a abordagem. A pesquisa se ancora nos conceitos de legitimidade e autoridade policial para discutir de que maneira estes aspectos são influenciados pela atual política de abordagem policial, que contabiliza mais de 14 milhões de abordagens realizadas anualmente sem avaliação crítica de sua efetividade. Foram utilizados métodos qualitativos baseados em entrevistas e análise documental. / This study aims to contribute to the analysis of police stop-and-frisk in the Brazilian context, seeking to identify the meanings attributed to this practice in the state of São Paulo. Using an interpretive approach, the work aims to identify and compare the meanings of the stop-and-frisk policy both in terms of its formulation and implementation. It also seeks to infer to what extent the relationship between the police and the community interferes with the way police officers implement stop-and-frisk policy. The research discusses how the current stop-and-frisk policy affects police officers’ authority and police legitimacy. Annually, the Military Police of the state of São Paulo conducts more than 14 million stop-and-frisks without critical evaluation of their effectiveness. Qualitative methods based on interviews and document analysis were used.

By means of a dialogical pedagogical dynamics, and using the production of stop motion pictures as the basis upon which the students construct historic speeches, it aims at enlacing the study of History and the numerous languages occurring at present. The dialogues established during classes, before primary and secondary historical sources, are analyzed according to the concept of cultural circularity and the sign's paradigm proposed by Carlo Ginzburg, whose theoretical sources are Mickail Bakhtin language studies.

Detta projekt har producerats i samarbete med Abu Garcia i Svängsta, Blekinge. Vårat projekt är en interaktiv produkt presentation gjord i flash med inslag av 3d, video och ljud. Våran tanke är att användaren ska kunna se hur en Ambassadeur Record fiskerulle ser ut både på insidan och utsidan, hur den fungerar och vad som gör den så unik. Det finns också video filmer som beskriver tillverknings processen, och hur man som förstagångs användare använder en Ambassadeur rulle. Design och bakgrundsljud är anpassad så att den ska väcka en känsla av fiske och fridfull utomhus miljö. / This project has been produced in cooperation with Abu Garcia in Svängsta, Blekinge.

Seit der Liberalisierung im Jahr 2013 wächst die Anzahl der Fernbusfahrgäste immer weiter an. Durch ein vielfältiges Streckenangebot und günstige Ticketpreise erfreut sich der Fernbus immer größerer Beliebtheit und ist zu einer guten und umweltfreundlichen Alternative für Fernreisen geworden. Allerdings kann die Reisezeit bei den Angeboten der Konkurrenten wenig mithalten, was vor allem an der Lage der Haltestellen liegt. In dieser Arbeit wird mittels auswahlbasierter Conjoint-Analyse die Kundensicht zu Haltestellen in der Stadt und Hal-testellen in Routennähe untersucht. Dabei nehmen vor allem Reisezeit und Reisekosten Einfluss auf die Entscheidung. Sozioökonomische Merkmale von Kunden spielen nur eine untergeordnete Rolle. Es kann gezeigt werden, dass Haltestellen in Routennähe für Fernbusse eine ernstzunehmende Alternative darstellen, ungeachtet von der Länge der Strecke, solang eine gute Anbindung an das Netz des öffentlichen Nahverkehrs gegeben ist. / Since the liberalisation in 2013, the amount of intercity bus users is continuously increasing. The concept of offering a large variety in routes as well as attractive pricing, helps intercity buses to a great popularity. Moreover, this option of traveling impresses with its eco-friendliness. Due to the location of the bus stops, the traveling time in intercity busses cannot keep up with the one of comparable competitors. Within this thesis, a selective conjoint analysis is conducted. The goal is to gain an insight on the option of potential customers towards bus stops within the city compared to their view of bus stops close to the traveling route. The decision is primarily based on travel costs and travel time whereas socioeconomic factors are only considered briefly. Concluding, bus stops close to the traveling route are an alternative choice for as long as they are located within reach of local public transportation.

This thesis explores the role of age in second language (L2) acquisition and first language (L1) attrition. The focus is on Voice Onset Time (VOT) in the production and categorical perception of word-initial L1 and L2 stops in highly advanced L1 Spanish learners of L2 Swedish. Using as the point of departure a maturational constraints perspective and the Critical Period Hypothesis (CPH), Study I examines the impact of age of onset (AO) of L2 acquisition on the production of L2 Swedish voiceless stops. The results show that there are AO effects even in the speech of highly advanced L2 learners and that the incidence of nativelike L2 learners is considerably lower than earlier assumed. However, conclusions like these are only possible when speaking rate is accounted for, thereby highlighting the importance of speaking rate effects on VOT as a measure of nativelikeness. Like Study I, Study II reveals age effects on the same L2 learners’ categorical perceptions of L2 Swedish stops. Moreover, after combining the results with the data from Study I, the incidence of nativelike behavior drops remarkably with no late L2 learner performing within the range of native-speaker production and perception. The results suggest that L2 acquisition of phonetic/phonological aspects is especially sensitive to AO effects. It is concluded that theories on maturational constraints, including the CPH, cannot be refuted on the basis of the present data. Study III concerns the same participants’ production and perception of L1 Spanish stops. Age of reduced contact (ARC) is identified as an important predictor for L1 attrition and retention of voiceless stop production, although not of stop perception. This discrepancy is related to different activation thresholds as proposed by the Activation Threshold Hypothesis (ATH). It is further suggested that early bilinguals are more dependent on high-frequency L1 use than late bilinguals when compensating for age effects, but only in production. / <p>At the time of doctoral defence the following papers were unpublished and had a status as follows: Paper 1: Accepted.

Masters in Public Administration - MPA / Whilst policy formulation has been extensively studied and theorised in the literature, far less attention has been paid until fairly recently to the issue of policy implementation. For a long time it was more or less assumed that once policy was formulated, implementation was a relatively straightforward administrative matter. In the past twenty or thirty years, however, public administration scholars (such as Pressman and Wildavsky and, in the South African context, Brynard and de Coning) have devoted more attention to unravelling the complexities of policy implementation. The current study intends to apply these more theoretical approaches to an analysis of the implementation of the 1997 White Paper for Social Welfare with particular respect to children in conflict with the law, focusing specifically on the One Stop Child Justice Centre in Mangaung, Bloemfontein. Welfare Service in South Africa before 1994 had a racial bias with services mostly unavailable to the majority of the citizens of the country. The 1997 White Paper for Social Welfare, based on a developmental approach to social welfare, was designed to take the country in a new and inclusive direction. In line with South Africa’s 1996 ratification of the UN Convention on the Rights of the Child, as well as other international instruments, Section 4 of Chapter 8 of the White Paper focuses on crime prevention through development and restorative justice, and recommends diversion wherever possible in the case of juveniles. With respect to Juvenile justice, this section of the White Paper makes provision for the establishment of One Stop Child Justice Centres, where a variety of services, from Social Development, the Department of Justice, the South African Police Services, Correctional Services, and the NPA, would be available to clients under one roof. All of these role players, it was envisaged, would operate as a multi-disciplinary team to achieve the objectives of the White Paper with respect to developmental and restorative forms of justice. The Centre at Mangaung is one of only a few centres to have been established as yet in South Africa. Although focusing in particular on the implementation of the 1997 White Paper, the study is also informed by other policy and legislative measures with respect to juvenile justice, in particular the Child Justice Bill of 2002 (now the Child Justice Act of 2008) and the Probation Services Amendment Act of 2002. It is generally accepted by the Government and its critics alike that the policy scene in South Africa in the period since 1994 has been characterized by good policies but poor execution. This is, however, a relatively untested hypothesis and needs further investigation. In the light of this, it is anticipated, that the present study will make a contribution to the literature on policy implementation in South Africa, as well as providing useful insights and lessons that can inform general government policy in this regard, and policy with respect to juvenile justice in particular. Within the general context of the 1997 White Paper for Social Welfare and the Department of Social Development’s Integrated Service Delivery Model, and the specific context of the Mangaung One Stop Child Justice Centre, the overall purpose of the study is to scrutinize the apparent discontinuity between policy design on the one hand and policy implementation on the other. More specifically, though, the objectives of the study are: (i) to examine the content of the 1997 White Paper for Social Welfare in general and more specifically the section on children in conflict with the law, (ii) to provide a historical overview of the delivery of services to youth in conflict with the law prior to the first democratic elections (1994) in South Africa, (iii) to examine what the concept of ‘integrated service delivery’ means to the different role-players at the One Stop Child Justice Centre, (iv) to examine the existing resources (human, financial and other) for successful implementation of the policy,(v) to examine whether there are procedures in place to encourage co-operation among stakeholders at the One Stop Child Justice Centre, (vi) to examine the successes, challenges and opportunities presented by the implementation of this policy at the One Stop Child Justice Centre and, (vii) to identify gaps between policy and implementation and make recommendations towards more successful implementation. Detailed semi-structured interviews were conducted with the Centre Manager and senior representatives of all the services involved (Social Development, the SAPS, Magistrates, the Probation Service, and Prosecutors). The interview questions focus mainly on implementation issues and challenges, but also gather information on the knowledge of the interviewees on the content of the policy. In addition, in order to validate and compare the data collected from these respondents, semi-structured interviews were held with six parents/guardians of children in conflict with the law who had been serviced by the centre. Official documents of the centre, such as annual reports, were also consulted for purposes of triangulation. Detailed transcripts will be made of all the interviews. In analysing the data, use was made in particular of the 5C Protocol advocated by Brynard and De Coning (2006) in their study of policy implementation in South Africa. The five C’s include the Content of the policy, the Context in which the policy is implemented, Commitment from those implementing the policy, the role of Clients and Coalitions, and the Capacity of those tasked with implementing the policy. In addition other C’s which have an impact on policy implementation (such as communication, co-ordination, and change management) will also be considered. Confidentiality of data gathered and anonymity of respondents were ensured by not requiring any personal details from the survey instruments. The sole purpose of using the data gathered for research was communicated to the respondents on the front page of the survey instruments. The choice of also not answering questions raised was respected.

The Ghost Machine is a practice-based research project that explores the process of embodiment in animated film. It describes the process of transfiguration from the artist’s/auteur’s point of view and not from an outside position. The dissertation follows the embodiment of a dramatic text, the Ghost Sonata by August Strindberg (1907), into an animated film. The starting point is my experience of the drama, at the age of thirteen, when staged by Ingmar Bergman at the Royal Dramatic Theatre. As a teenager, the world of the grown-ups seemed to be corrupt, twisted and ruled by violent power plays and economic sanctions, and this play confirmed my world view. Was I right, as a thirteen-year-old boy? What kind of world emerges in my version of the Ghost Sonata? In this thesis work, the films and the experimental research process meet the practice and art of writing. Using text, not as “theory” separated from “practice” but as a bodily art practice, creates a shifting border between the results and intentions of art and filmmaking, and the results of writing. At the same time a unity emerges where the results of the research process can be seen and experienced in the interaction between the texts and the artwork. The Ghost Machine is a totality where the text, films and artworks included in the project are equally important and must be seen as a unity. The Ghost Machine is a work journey where travelling, animated film practice, networking with colleagues and collecting data are mixed with experiments using methods from contemporary arts practice, performance, reenactment, appropriation and transfiguration, blended with traditional puppet animation in classic Czech style. In collaboration with actors, mime artists, puppet makers, musicians and a minimal film crew, century old stop-motion animation is combined with computer animation.  The textual part of the work falls into two categories: life stories and work stories. The work stories traces the forming of an artwork in all aspects. The life stories are related to the subject of ghosts. Suddenly, dead friends and dear family members claimed their space. The understanding of the Ghost Sonata came to be a process of sorting out and following lines of memory using an inverted version of the Orpheus myth as a guide. Instead of never turning around, when walking the dead out of oblivion, I chose to look back, again and again, until I hit something and could not write anymore. / https://www.uniartsplay.se/slin
