Syftet med denna studie är att synliggöra hur lärare undervisar i folkmusik. Studien tar både upp förhållningssätt till den gehörstradition som folkmusik bygger på, hur utbildningen har påverkat musiken och vilka konkreta metoder lärare använder i sin undervisning. Bakgrundslitteraturen sätter folkmusik och undervisning i ett historiskt perspektiv och den tidigare forskningen tar upp begrepp som metodik, institutionalisering, gehör och tyst kunskap. Arbetet studeras utifrån ett sociokulturellt perspektiv. För att samla in material till studien har semistrukturerade intervjuer använts och dessa har sedan analyserats tematiskt. I resultatet presenteras lärarnas metodiska tankesätt kring genrespecifika övningar som antingen har utformats på egen hand, utifrån låtar eller utifrån existerande material som har anpassats till genren. Vidare framkommer tankar kring tyst kunskap i en gehörstradition och hur detta ses i relation till utbildning. En folkmusikmetodik som är på väg att formas och utvecklas genom att folkmusiken har tagit plats i utbildningsmiljön är något som diskuteras av respondenterna. Diskussionen tar upp hur nya redskap för lärande utvecklas när musiken hamnar i nya kontexter och vilka redskap lärare tycker är viktiga för lärandet av fiol och folkmusik. / The main goal of this study is to examine the methodology in the teaching of fiddle, used by teachers in traditional music. The study examines the approaches to the tradition of learning music by ear which is central to the teaching of traditional music, how education has affected music and which methods teachers use in their tuition. The background literature sets traditional music and teaching traditional music in a historical perspective. Previous research studies address concepts such as methodology, institutionalization, learning music by ear and silent knowledge. Material for the study is collected through semi-structured interviews. The interviews were transcribed and then analyzed thematically. The result presents the teachers' methodical way of thinking about genre-specific exercises. These have either been designed by themselves, based on tunes or based on existing material that has been adapted to the genre. Furthermore, thoughts emerge about silent knowledge in a learning by ear-tradition and how this is seen in relation to education. A traditional music methodology that is about to be shaped and developed, due to traditional music taking place in the educational environment, is discussed by the respondents. The discussion addresses how new tools for learning develop when the music is put in new contexts and which tools teachers think are important for the learning of fiddle and traditional music.

This essay is a scientific essay that centers around a story based on a self-experienced dilemma about a shy and silent child who does not communicate with the pedagogues at the preschool nor the majority of the other children. The child chooses to only communicate through her best friend and is then able to use both body- and verbal language, and it is only through this friend that others learn what the child wants.   The purpose of the essay is to examine how preschools satisfy the needs of silent and shy children, by studying my own actions in the described story. The questions at issue which are studied in this essay include how I as a future preschool teacher can support the silent and withdrawn children. Which tools and strategies pedagogues can use to uplift them. How I as a pedagogue can include these children and make them participate in the preschool’s activities. As well as how pedagogues relate to the need of interaction among silent children. These questions are answered through the writing of the essay where my practical knowledge, which constitutes of 17 years of working as a caretaker of children, and theoretical perspectives such as the theory of connection and a sociocultural perspective are applied. An interview with a certified speech therapist has also been conducted. The conclusions that can be made are that there are several possible tools and strategies that can be used to include and facilitate for the silent and shy children in the preschool, for example picture-support, smaller groups of children or that you as an pedagogue participate yourself and give the child roles within the plays that it is able to manage. Furthermore, an important lesson is that the theoretical perspectives constitute a crucial support for pedagogues in their approach towards shy children, that it is important to do a mapping of the shy children in terms of what causes the difficulties and when they arise, and also to always proceed from the individual child’s needs so that every child at the preschool gets the best possibilities for education. / Denna uppsats är en vetenskaplig essä som utgår ifrån en berättelse som utgörs av ett egenupplevt dilemma om ett blygt och tystlåtet barn som inte kommunicerar med pedagogerna på förskolan eller majoriteten av de andra barnen. Barnet väljer att endast att kommunicera via sin bästa kompis och kan då använda både kroppsspråk och verbalt språk, och det är endast genom kompisen som andra får veta vad barnet vill. Syftet med uppsatsen är att undersöka hur förskolan tillgodoser tystlåtna och blyga barns behov, genom att studera mitt eget handlade i den beskrivna berättelsen. De frågeställningar som studeras i uppsatsen inkluderar hur jag som framtida förskolelärare kan stödja de tystlåtna och tillbakadragna barnen. Vilka verktyg och strategier pedagoger kan använda för att lyfta fram dem. Hur jag som pedagog kan inkludera dessa barn och få dem delaktiga i aktiviteterna på förskolan. Samt hur pedagoger förhåller sig till behovet av samspel hos tystlåtna barn. Dessa frågeställningar besvaras genom essäskrivande där min praktiska kunskap, som består av 17 års arbete som barnskötare, samt teoretiska perspektiv som anknytningsteorin och ett sociokulturellt perspektiv tillämpas. En intervju med en legitimerad logoped har också genomförts. Slutsatser som kan dras är att det finns flera möjliga verktyg och strategier som kan användas för att inkludera och underlätta för de tystlåtna och blyga barnen i förskolan, bland annat bild-stöd, mindre barngrupper eller att man som pedagog själv deltar och ger barnet roller i leken som den klarar av. En viktig lärdom är vidare att de teoretiska perspektiven utgör ett väsentligt stöd för pedagoger i sitt bemötande av blyga barn, att det är viktigt att göra en kartläggning av de blyga barnen kring vad som orsakar svårigheterna och när de uppstår, samt att alltid utgå från det enskilda barnets behov så att alla barn på förskolan får de bästa förutsättningarna för lärande.

The paper is devoted to the investigation of behavioral equivalences of concurrent systems modeled by Petri nets with silent transitions. Basic τ-equivalences and back-forth τ-bisimulation equivalences known from the literature are supplemented by new ones, giving rise to complete set of equivalence notions in interleaving / true concurrency and linear / branching time semantcis. Their interrelations are examined for the general class of nets as well as for their subclasses of nets without siltent transitions and sequential nets (nets without concurrent transitions). In addition, the preservation of all the equivalence notions by refinements (allowing one to consider the systems to be modeled on a lower abstraction levels) is investigated.

Föreliggande systematiska litteraturstudie presenterar tidigare forskning om litteratursamtal och introverta elever. Syftet är att undersöka hur lärare kan genomföra litteratursamtal med introverta elever. Studien inkluderar 14 publikationer där doktorsavhandlingar, vetenskapliga artiklar och facklitteratur ingår. Mycket av forskningen utgår från det sociokulturella perspektivet. Materialet har bearbetats genom en innehållsanalys och kategoriserats efter tre teman; introverta elever, litteratursamtal samt strukturerade samtal med tystlåtna elever.  Studiens resultat visar att introverta elever ofta har en tystlåten framtoning. De har behov av en trygg lärmiljö med möjlighet till återhämtning. Introverta elever föredrar enskilt eller omsorgsfullt strukturerat arbete i mindre grupper. I och med införandet av läroplanen lgr 22 kommer strukturerade samtal, såsom litteratursamtal ges ett större utrymme i svenskundervisningen. Forskning visar att elever förhåller sig positiva till litteratursamtal. Det finns dock didaktiska fallgropar med litteratursamtal då de ibland används mer som förhör än som ett dialogiskt textsamtal. Forskningsresultat beträffande elevers lärande i samband med samtal går isär. Viss forskning menar att mindre verbalt aktiva elever löper en risk att klara sig sämre i skolan, medan annan forskning visar att muntligt deltagande inte nödvändigtvis måste vara en förutsättning för lärande.

After over a decade of its discovery, the Electroretinogram (ERG) still remains the objective tool that is conventionally used in assessment of retinal function in health and disease. Although there is ongoing research in developing ERG- recording techniques, interpretation and clinical applications, there is still a limited understanding on how each photoreceptor class contribute to the ERG waveform and their role and/or susceptibilities in various retinal diseases still remains unclear. Another limitation with currently used conventional testing protocols in a clinical setting is the requirement of an adaptation period which is time-consuming. Furthermore, the ERG responses derived in this manner are recorded under different stimulus conditions, thus, making comparison of these signals difficult. To address these issues and develop a new testing method, we employed silent substitution paradigm in obtaining cone- and rod- isolating ERGs using sine- and square- wave temporal profiles. The ERGs achieved in this manner were shown to be photoreceptor-selective. Furthermore, these responses did not only provide the functional index of photoreceptors but their contributions to their successive postreceptoral pathways. We believe that the substitution stimuli used in this thesis could be a valuable tool in functional assessment of individual photoreceptor classes in normal and pathological conditions. Furthermore, we speculate that this method of cone/rod activity isolation could possibly be used in developing faster and efficient photoreceptor-selective testing protocols without the need of adaptation. / Bradford School of Optometry and Vision Sciences

Cette thèse porte sur l’examen des distorsions communicationnelles à partir de communications établies entre les enfants vulnérables et le personnel à l’intérieur de la société de l’Imam Ali. Ces communications ont été étudiées à la lumière des vécus des enfants dans les trois dimensions de la vie des enfants vulnérables. Il s’agit des dimensions psychosociale (parcours et histoires des enfants placés dans les maisons d’accueil), communautaire (famille et groupes sociaux proches) et sociale; et nous l’avons fait en nous rattachant à la théorie de l’agir communicationnel de Habermas (1987), en tenant compte de la structure éthico-politique de la société iranienne. Pour ce faire, nous avons aussi introduit des concepts de vulnérabilité et de violence dans la ligne d’une objectivation des distorsions communicationnelles dans le cas d’enfants vulnérables. Cette question a été traitée comme étant une question éthique à partir de discours des enfants et du personnel par rapport à la question suivante : vers quoi s’orientent les communications entre les deux champs humains qui interagissent dans les maisons d’accueil de la société de l’Imam Ali, soit les enfants et les membres du personnel? Vont-elles plutôt dans le sens de la contrainte ou plutôt dans le sens de la coopération (communicationnel)? La méthodologie de recherche est partie d’une approche logico-pragmatique fondée sur l’argumentation. Elle est basée sur certaines contributions théoriques de la logique naturelle (Grize, 1996) et sur l’éthique de la discussion (Habermas, 1987-2013). Selon nos résultats, il existe une zone de violence qui se trouve à la racine de la religion islamique. L'étude a révélé que les sujets vulnérables subissent à la fois de la violence visible et de la violence silencieuse provenant des structures sociales, cela rendant leur état de plus en plus vulnérable et précaire. De plus, le monde des enfants est colonisé par une communication dirigée vers un « non-dialogue » dans l’espace dédié à leur protection. Il ressort de cette étude que les communications établies dans les maisons d’accueil se basent sur une éthique de la religion islamique, et elles mènent par-là à des chemins représentant des processus de reconnaissance et de socialisation religieuse. Les propos que nous avons fait émerger nous ont permis d’affirmer l’existence d’une forte contrainte d’ordre religieux – voir la violence silencieuse. C’est pourquoi ces espaces de vie ne remplissent pas les conditions préalables à la réalisation d’une éthique de discussion dans le sens habermassien. Cette recherche révèle un cycle de violence silencieuse inscrit dans les structures sociales de l’Iran et perturbant le contexte de l’agir communicationnel dans un contexte d’enfants vulnérables. La conséquence en est l’émergence d’un processus de déformation qui entraîne des distorsions communicationnelles. L’étude a ouvert la voie à une nouvelle piste de recherche dirigée vers les distorsions communicationnelles qui révèlent de nouveaux aspects pathogènes d’une contrainte exercée par un pouvoir politico-administratif. / This thesis focuses on the study of distortions of communications between the vulnerable children served by the Imam Ali Society and its staff. These communications were studied by looking at three dimensions of the experiences of those children, namely, the psychosocial dimension (paths and stories of the children placed in foster homes), the community dimension (family and close social groups) and the social one. It was carried out by employing Habermas's theory of communicative action (1987) while taking into account the ethico-political structure of the Iranian society. For this purpose, we also introduced concepts of vulnerability and violence in order to objectify communication distortions in the case of vulnerable children. The problem was approached as an ethical conundrum in the children and staff interactions regarding the following questions: in which direction is the communications between the children and the staff in the Imam Ali Society Shelter taking place? Are they more in the direction of constraint or rather in the direction of cooperation? The methodology of this research is part of a logico-pragmatic approach based on argumentation. It is based on certain theoretical contributions of natural logic (Grize, 1996) and the discourse ethics theory (Habermas, 1987-2013). According to our results, there is a zone of violence and increased vulnerability, source of which is mostly routed in Islam. This research also leads us to identify a zone of vulnerability, where the vulnerable are exposed to both visible and silent violence from social structures, making their condition more and more vulnerable and precarious. In addition, the children's lives are colonized by a communication directed towards a "non-dialogue" in the social space rather than one dedicated to their protection. The study indicates that communications established in the shelter of the Imam Ali Society are based on Islamic ethics, leading thereby to paths representing processes of religious recognition and socialization. This research identified the existence of a strong religious constraint i.e., silent violence. For this reason, these spheres of life do not fulfill the preconditions for realization of a Habermassian ethical discourse theory. Our work demonstrates a cycle of silent violence embedded in the Iran's social structures, disrupting communication in the context of vulnerable children. The consequence is the emergence of deformation processes that lead to communication distortions. This research paved the way for a new line of research on communication distortions revealing new pathogenic aspects of a constraint exerted by a politico-administrative power.

Outlined herein is the Modular Vehicle [MODV] concept as a cost effective, utilitarian, and highly functional vehicle concept for the changing demands placed on a MAGTF [Marine Air-Ground Task Force] or SP-MAGTF [Special Purpose Marine Air-Ground Task Force] in the 21st century. A large focus is put on the importance of modularity and cost effectiveness of having a 24 hour configurable vehicle to a specific mission and area of operation. Off-road vehicle progression through history is presented and successful design features are noted in order to develop underlying goals for the modular vehicle. The thesis emphasizes recent technology advancements that can shift the foundations of vehicle design including wheel hub motors, high capacity batteries, solid oxide fuel cells, autonomy, structural health monitoring, energy harvesting shock absorbers, non-pneumatic tires, and drive-by-wire options. Predictions on the outlook for the technology progressions is discussed to give insight into the viability of basing a vehicle concept on these technologies. Finally, physical design bounds are presented to provide a foundation for the future design of such a vehicle. / Master of Science

The subject of this thesis is Slovak mime theatre. It begins with the connections to the period of its foundation and introduces topic about founder of Slovak mime theatre - Milan Sládek. The next part of the thesis focuses on Slovak amateur theatre artists and their work at the time when professional mime theatre didn't exist in Slovakia. These artists used to experiment with different kinds of theatre technics, including mime theatre. Last part is based on analysis work and performances of the modern authors - Miroslav Kasprzyk, Štefan Capko, Juraj Benčík, Tomáš Kasprzyk, Valéria Daňhová, Barbora Debnárová, Pavol Seriš and modern theatre companies - Puppet Thetare Žilina, Debris Company, Teatro Tatro and Theatre Silent Sparks. It describes how the character of Slovak mime theatre has changed within more than fifty years of existence.
