Caractéristiques et origine fonctionnelle des propriétés fréquentielles du noeud auriculoventriculaire

Le nœud auriculoventriculaire (AV) joue un rôle vital dans le cœur normal et pathologique. Il connecte les oreillettes aux ventricules et, grâce à sa conduction lente, génère un délai entre les contractions auriculaire et ventriculaire permettant d’optimiser le pompage sanguin. Sa conduction lente et sa longue période réfractaire font du nœud AV un filtre d’impulsions auriculaires lors de tachyarythmies assurant ainsi une fréquence ventriculaire plus lente favorable au débit cardiaque. L’optimisation de ce filtrage est une cible dans le traitement de ces arythmies. Malgré ce rôle vital et de nombreuses études, le nœud AV demeure l’objet de plusieurs controverses qui en rendent la compréhension laborieuse. Nos études expérimentales sur des préparations isolées de cœurs de lapin visent à apporter des solutions à certains des problèmes qui limitent la compréhension des propriétés fréquentielles du nœud AV. Le premier problème concerne la définition de la propriété de récupération nodale. On s’accorde généralement sur la dépendance du temps de conduction nodale (intervalle auriculo-Hissien, AH) du temps de récupération qui le précède mais un débat presque centenaire persiste sur la façon de mesurer ce temps de récupération. Selon que l’on utilise à cette fin la longueur du cycle auriculaire (AA) ou l’intervalle His-auriculaire précédent (HA), la même réponse nodale montre des caractéristiques différentes, un paradoxe à ce jour inexpliqué. Le temps de conduction nodale augmente aussi avec le degré et la durée d'une fréquence rapide, un phénomène appelé fatigue. Or, les caractéristiques de la fatigue mesurée varient avec l’indice de récupération utilisé (AA vs. HA). De plus, une troisième propriété appelée facilitation qui entraîne un raccourcissement du temps de conduction diffère aussi avec l’indice de récupération utilisé. Pour établir l’origine de ce problème, nous avons déterminé les différences entre les courbes de récupération (AH compilé en fonction du AA ou HA) pour 30 états fonctionnels nodaux différents. Ces conditions étaient obtenues à l’aide de protocoles permettant la variation du cycle de base (BCL) et du cycle prétest (PTCL), deux paramètres connus pour altérer la fonction nodale. Nous avons pu établir que pour chaque état fonctionnel, la forme de la courbe de récupération et le niveau de fatigue étaient les mêmes pour les deux indices de récupération. Ceci s’applique aussi aux données obtenues à des BCL et PTCL égaux comme dans les protocoles de stimulation prématurée conventionnels couramment utilisés. Nos résultats ont établi pour la première fois que les propriétés nodales de récupération et de fatigue sont indépendantes de l’indice de récupération utilisé. Nos données montrent aussi que les différences entre les courbes de récupération en fonction de l’indice utilisé proviennent d’effets associés aux variations du PTCL. Notre deuxième étude établit à partir des mêmes données pourquoi les variations du PTCL altèrent différemment les courbes de récupération selon l’indice utilisé. Nous avons démontré que ces différences augmentaient en proportion directe avec l’augmentation du temps de conduction au battement prétest. Cette augmentation cause un déplacement systématique de la courbe construite avec l’intervalle AA vers la droite et de celle construite avec l’intervalle HA vers la gauche. Ce résultat met en évidence l’importance de tenir compte des changements du temps de conduction prétest dans l’évaluation de la fonction nodale, un paramètre négligé dans la plupart des études. Ce résultat montre aussi que chacun des deux indices a des limites dans sa capacité d’évaluer le temps de récupération nodale réel lorsque le temps de conduction prétest varie. Lorsque ces limites sont ignorées, comme c’est habituellement le cas, elles entraînent un biais dans l’évaluation des effets de fatigue et de facilitation. Une autre grande difficulté dans l’évaluation des propriétés fréquentielles du nœud AV concerne son état réfractaire. Deux indices sont utilisés pour évaluer la durée de la période réfractaire nodale. Le premier est la période réfractaire efficace (ERPN) définie comme l’intervalle AA le plus long qui n’est pas conduit par le nœud. Le deuxième est la période réfractaire fonctionnelle (FRPN) qui correspond à l’intervalle minimum entre deux activations mesurées à la sortie du nœud. Paradoxalement et pour des raisons obscures, l’ERPN augmente alors que la FRPN diminue avec l’augmentation de la fréquence cardiaque. De plus, ces effets varient grandement avec les sujets, les espèces et l’âge. À partir des mêmes données que pour les deux autres études, nous avons cherché dans la troisième étude l’origine des variations fréquentielles de l’ERPN et de la FRPN. Le raccourcissement du BCL prolonge l’ERPN mais n’affecte pas la FRPN. L’allongement de l’ERPN provient principalement d’un allongement du temps de conduction prétest. Un PTCL court en comparaison avec un BCL court allonge encore plus substantiellement le temps de conduction prétest mais raccourcit en même temps l’intervalle His-auriculaire, ces deux effets opposés s’additionnent pour produire un allongement net de l’ERPN. Le raccourcissement de l’intervalle His-auriculaire par le PTCL court est aussi entièrement responsable pour le raccourcissement de la FRPN. Nous avons aussi établi que, lorsque la composante du temps de conduction prétest est retirée de l’ERPN, un lien linéaire existe entre la FRPN et l’ERPN à cause de leur dépendance commune de l’intervalle His-auriculaire. Le raccourcissement combiné du BCL et du PTCL produit des effets nets prévisibles à partir de leurs effets individuels. Ces effets reproduisent ceux obtenus lors de protocoles prématurés conventionnels. Ces observations supportent un nouveau schème fonctionnel des variations fréquentielles de l’ERPN et de la FRPN à partir des effets distincts du BCL et du PTCL. Elles établissent aussi un nouveau lien entre les variations fréquentielles de l’ERPN et de la FRPN. En conclusion, la modulation fréquentielle de la fonction du nœud AV provient de la combinaison d’effets concurrents cumulatifs liés au cycle de base et non-cumulatifs liés au cycle prétest. Ces effets peuvent être interprétés de façon consistante indépendamment de l’indice de récupération en tenant compte des changements du temps de conduction au battement prétest. Les effets fréquentiels disparates sur l’ERPN et la FRPN sont aussi grandement liés aux changements du temps de conduction prétest. Lorsque l’analyse tient compte de ce facteur, l’ERPN et la FRPN montrent des variations parallèles fortement liées à celles de l’intervalle His-auriculaire. Le nouveau schème fonctionnel des propriétés fréquentielles du nœud AV supporté par nos données aidera à mieux cibler les études sur les mécanismes cellulaires contrôlant la modulation fréquentielle nodale. Nos données pourraient aider à l’interprétation et au contrôle des réponses nodales diverses associées aux tachyarythmies supraventriculaires et à leur traitement pharmacologique. En bref, nos travaux supportent une compréhension factuelle améliorée du comportement fréquentiel du nœud AV, un domaine aux applications multiples en rythmologie cardiaque.

Visualizing digital media interactions : providing feedback on jam2jam AV performances

Instrumental music performance is a well-established case of real-time interaction with technology and, when extended to ensembles, of interaction with others. However, these interactions are fleeting and the opportunities to reflect on action is limited, even though audio and video recording has recently provided important opportunities in this regard. In this paper we report on research to further extend these reflective opportunities through the capture and visualization of gestural data collected during collaborative virtual performances; specifically using the digital media instrument Jam2jam AV and the specifically-developed visualization software Jam2jam AV Visualize. We discusses how such visualization may assist performance development and understanding. The discussion engages with issues of representation, authenticity of virtual experiences, intersubjectivity and wordless collaboration, and creativity support. Two usage scenarios are described showing that collaborative intent is evident in the data visualizations more clearly than in audio-visual recordings alone, indicating that the visualization of performance gestures can be an efficient way of identifying deliberate and co-operative performance behaviours.

Don's Party and the AV Jennings type 15 home

Australian housing underwent a watershed when 1960s mass-produced houses slowly started subscribing to a new aesthetic of continuous living spaces, known as the ‘open plan’ home. This created a new landscape for Australian playwrights to observe and explore in their work when representing domesticity on the stage. Instead of representing a single room of the house on the stage, plays such as ‘Don’s Party’, started to work with a number of openly connected spaces bound by doorways to private sections of the house or to specific outdoor areas. In representing this dialectic between interior and the exterior, private and public spaces in the home, the continuous spaces of the AV Jennings house in ‘Don’s Party’ acted to blur these conditions creating an outer interior. These connected spaces became the place for an outward performance on the family’s interiority, while simultaneously presenting a boundary to an inner interior in the offstage spaces of the home. This paper focuses on the play 'Don's Party' by David Williamson and how the spatial arrangements of the AV Jennings home, in which it was set, influenced the playwright. The research includes a textual analysis of the play, biographical research and interviews with the playwright alongside an analysis of the spatial arrangements of AV Jennings houses.

The micro quadrotor is complete with a 9 Degree of Freedom Inertial Measurement Unit, a Gumstix Overo® Computer-On-Module which can run the widely used Robot Operating System (ROS) for use with other research algorithms.

Utelämning i AV-översättning : En studie av textning i tre olika genrer

Tutkielman tavoitteena on kvalitatiivisen ja kvantitatiivisen analyysin avulla selvittää, millaisia poisjättöjä erityyppiset ohjelmat sisältävät. Tutkimusmateriaalina on lastenohjelma (Sune och hans värld), dokumentti (Yrke: kung) ja keskusteluohjelma (Bettina S) sekä niiden suomenkieliset tekstitykset. Jokaisesta ohjelmasta on analysoitu 15 minuuttia. Poisjättöjen luokittelussa pohjana on Koljosen (1995, 1997 ja 1998) luokittelu, joka koostuu kolmesta pääluokasta ja useasta alaluokasta. Kolme pääluokkaa ovat fakultatiiviset lauseenjäsenet (fakultativa satsdelar), puhekieliset piirteet (talspråkliga drag) ja informatiiviset osaset (informativa fragment). Hypoteeseja tutkielmassa on kaksi: suurin osa poisjätöistä on puhekielisyyksiä, mikä johtuu median vaihtumisesta puhutusta kirjoitettuun, ja informaatiota ei häviä, vaikka paljon on jätettävä pois aika- ja tilarajoitusten takia. Teoriaosassa käsitellään katsojan (tekstityksen vastaanottajan) tärkeää asemaa, poisjättöjen syitä ja poisjättöjä Koljosen luokittelun mukaisesti. Lisäksi teoriaosassa esitellään materiaalina olevat ohjelmatyypit, eli lastenohjelma, dokumentti ja puheohjelma. Analyysiosasta käy ilmi, että ohjelmat sisältävät melko erilaisia poisjättöjä. Tämä johtuu siitä, että lastenohjelmassa dialogi perustuu käsikirjoitukseen, kun taas dokumentissa ja keskusteluohjelmassa puhe on vapaata. Dokumentti on tyypillinen esimerkki monologista, eikä sisällä dialogille tyypillisiä piirteitä, kuten dialogipartikkeleita tai tervehdyksiä. Analyysistä käy myös ilmi, että valinnaisia lauseenjäseniä on jätetty eniten pois. Tämä johtuu ainoastaan siitä, että poisjätettyjen konjunktioiden määrä on suuri. Koljonen ei ole luokitellut konjunktioita tutkimuksissaan. Konjunktiot voitaisiin laskea myös diskurssipartikkeleihin (puhekielisiin piirteisiin), koska niillä on selvästi puhetta ohjaileva funktio, jolloin ensimmäinen hypoteeseista osoittautuisi todeksi. Puhekielisten piirteiden määrä vaihtelee ohjelmatyypistä riippuen. Dokumentti sisältää paljon toistoa, joka voidaan jättää pois. Keskusteluohjelmassa on puolestaan paljon poisjätettyjä dialogipartikkeleita, jotka toimivat vastauksena kysymykseen tai lyhyinä kommentteina. Lastenohjelmassa poisjättöjen jakauma on tasaisin: mikään ryhmä ei prosentuaalisesti erotu joukosta. Poisjätettyjen informaatiota sisältävien osasten määrä ei myöskään ole merkittävä. Analyysin perusteella voidaankin sanoa, että kummatkin hypoteesit osoittautuivat todeksi.

Historiebruk kring Nådendal : och den kommemorativa anatomin av klostrets minnesplats

This thesis examines the ruins of the medieval Bridgettine (Birgittan) monastery of Naantali (Vallis Gratiae, f. 1443) in Finland and the transformation of the site into a national heritage and a memory landscape. It was archaeologically surveyed in the 19th century by Professor Sven Gabriel Elmgren (1817 1897). His work was followed by Dr. Reinhold Hausen (1850 1942), who excavated the site in the 1870s. During this time the memories of Saint Bridget (Birgitta) in Sweden were also invented as heritage. Hausen published his results in 1922 thus forming the connection with the next generation of actors involved with the Naantali site: the magnate Amos Anderson (1878 1961), the teacher Julius Finnberg (1877 1955) and the archaeologist Juhani Rinne (1872 1950). They erected commemorative monuments etc. on the Naantali site, thus creating a memory landscape there. For them, the site represented the good homeland in connection with a western-oriented view of the history of Finland. The network of actors was connected to the Swedish researchers and so-called Birgitta Friends, such as state antiquarian Sigurd Curman (1879 1966), but also to the members of the Societas Sanctae Birgittae and the Society for the Embellishment of Pirita, among others. Historical jubilees as manifestations of the use of history were also arranged in Naantali in 1943, 1993 and 2003. It seems as if Naantali is needed in Finnish history from time to time after a period of crisis, i.e. after the Crimean War in the 1850s, the civil war of 1918, during World War II and also after the economic crisis of the early 1990s. In 2003, there was a stronger focus on the international Saint Bridget Jubilee in Sweden and all over Europe. Methodologically, the thesis belongs to the history of ideas, but also to research on the use of history, invented traditions and lieux de mémoire. The material for the work consists of public articles and scholarly texts in books or newspapers and letters produced by the actors and kept in archives in Finland, Sweden and Estonia, in addition to pictures and erected commemorative monuments in situ in the Western Finnish region. Keywords: Nådendal, Naantali monastery, Bridgettines, St. Bridget, use of history, lieux de mémoire, invented traditions, commemorative anatomy, memory landscape, Saint Bridget jubilees , S. G.

"En plan för jämställdhet borde kanske utarbetas, men förekommer det ett behov?" : En kartläggning av 26 svenskspråkiga kommuners främjande av jämställdhet

Jämställdhetslagen från 1995 kräver att både myndigheter och arbetsgivare med aktiva och målinriktade åtgärder främjar jämställdheten, och denna pro gradu-avhandling undersöker närmare hur denna lag implementerats i de finlandssvenska kommunerna (kommuner med majoritetsspråk svenska) under en 10årsperiod. I kommunerna jobbar 80% kvinnor, och 38% av alla kvinnliga arbetstagare hittas i arbeten inom den offentliga sektorn. Kommunens skyldighet att trygga dessa kvinnors lika villkor inom kommunorganisationen ingår både som en del i arbetsgivaransvaret, men även som del i statens demokratiska utövande genom myndighetsansvaret. De tre planer som ingår i mitt material innehåller en kartläggning av jämställdhetsområdet i olika omfattning, definierade mål och åtgärder och ingen av planerna har följts upp efter att de godkänts. Planerna varierar både i utformning och omfattning men också i ansvarsspecificering och åtgärdernas konkretisering, vilken ger en varierande kvalitet och därmed även varierande förutsättning att genomdrivas och därmed uppfylla lagens ålägganden. Två av kommunerna har eller har haft en jämställdhetskommitté. I de 26 inkomna svarsformulär görs en närläsning av hur begreppet jämställdhet används och hur jämställdhetslagen tolkas och orsakerna till frånvaron av jämställdhetsåtgärder. På frågan om varför jämställdhetsarbetet inte genomförts helt eller delvis utkristalliserade sig sex olika argumentationsteman: 1. Myten om den jämställda kommunen, innebär en hänvisning till att det inte förekommit några problem med jämställdheten. 2. Den naturligt integrerade jämställdheten, är kommunens policy och sker utan planer, men en liten kritik av problematiken med frånvaron av planer framförs av några kommuner. 3. Könens komplettering, utgår jämställdhetsbegreppet ifrån i några kommuner. 4. Den matematiska jämställdheten, är argument där man genom hänvisningar till kvinnor på olika högre positioner visar på att jämställdheten är uppnådd. 5.En fråga om resurser, används som ett argument till jämställdhetsarbetets frånvaro i kommunen. 6. Avsaknad av intresse, hos personalen och allmänheten är ett annat argument för ogenomförda jämställdhetsåtgärder. Det framkommer tydligt i materialet att kommunerna anser sig följa jämställdhetslagen, samtidigt som det blir tydligt att det råder en oklarhet om vad jämställdhetslagen från 1995 egentligen innehåller. En tydlig sammanblandning mellan den lagstadgade kvoteringen och skyldigheten att aktivt främja jämställdhet träder fram i materialet. Det ofullständiga jämställdhetsarbetet strandar på olika punkter, men en avgörande anser punkt är oförståelsen inför begreppet jämställdhet och därmed också lagens syfte och innehåll. Avhandlingens slutsats är att frånvaron av en könsmaktanalys försvårar förståelsen av ojämställdhetens komplexhet, dvs. dess orsaker, mångskiftande funktion och olika uttryck i organisationens strukturer och i de handlande aktörerna.

Betydelser i barnfamiljsbroschyrer : Systemisk-funktionell analys av den tänkta läsaren och institutionen

This thesis concerns Swedish and Finland-Swedish brochures to families with children, presenting family allowances from the social insurance institutions in the two countries. The aim of the study is to analyse what meanings are conveyed with reference to the conceivable reader and the institution in the brochures. The material consists of information brochures in Swedish from Kela, the social insurance institution of Finland, and Försäkringskassan, the Swedish social insurance agency, issued during 2003–2006. The general theoretical framework is systemic-functional linguistics (SFL) as presented by Halliday & Matthiessen (2004) and Holmberg & Karlsson (2006). The study consists of a quantitative study of the lexical choices of the social insurance brochures. Furthermore, a qualitative process and participant analysis is annotated with the UAM Corpus tool and the results are quantified. Speech functions and modal auxiliaries are analysed qualitatively. The analysis shows that material and relational processes are most common. The relational and verbal processes are used more in the Sweden-Swedish brochures, while the material processes are more common in the Finland-Swedish brochures. The participants in the brochures are the institution, mentioned by its name, and the conceivable reader, directly addressed with “you” (du). In addition, the referent “child” is often mentioned. The participants assigned for the reader are Actor, Receiver, Carrier and Speaker. In the Finland-Swedish texts, the reader is often an Actor, while the reader in the Sweden-Swedish texts is a Carrier. Thus, the conceivable reader is an active participant who takes care of his or her own matters using the internet, communicates actively to the institution and has legal rights and obligations. The institution is visible in the texts but does not have an active role as the name of the institution is mostly used in circumstances. The institution is not often a participant, but when it is, it is Actor, Receiver, Listener and Carrier, expecting the clients to address it. Speech functions are performed in different ways. For instance, questions structure the reading process and commands are realised by modal auxiliaries, not by imperatives. The most common modal auxiliary is kan (can, may), and another common auxiliary is ska (shall, must). Statements are surrounded by subordinate clauses and adverbs that describe situations and criteria. The results of the study suggest that the brochures in the two countries are similar, in particular when produced in similar ways, that is, when the Finland-Swedish texts are not translated. Existing differences reflect the differences in the institutions, the social insurance systems and the cultural contexts.

Drag på parnassen. Två sextiotalsstudier. : Del I: Medelklass med mänskligt ansikte. Medelklassradikalism i fyra romaner av Christer Kihlman, Jarl Sjöblom, Marianne Alopaeus och Ulla-Lena Lundberg. Del II: Modernistdebatten. Sak, person och fält i en finlandssvensk litteraturdebatt år 1965.

The objective of my dissertation Pull (or Draught, or Moves) at the Parnassus , is to provide a deeper understanding of Nordic Middle Class radicalism of the 1960 s as featured in Finland-Swedish literature. My approach is cultural materialist in a broad sense; social class is regarded a crucial aspect of the contents and contexts of the novels and literary discussions explored. In the first volume, Middle Class With A Human Face , novels by Christer Kihlman, Jarl Sjöblom, Marianne Alopaeus, and Ulla-Lena Lundberg, respectively, are read from the points of view of place, emotion, and power. The term "cryptotope" is used to designate the hidden places found to play an important role in all of these four narratives. Also, the "chronotope of the provincial small town", described by Mikhail Bakhtin in 1938, is exemplified in Kihlman s satirical novel, as is the chronotope of of war (Algeria, Vietnam) in those of Alopaeus and Lundberg s. All the four novels signal changes in the way general "scripts of emotions", e.g. jealousy, are handled and described. The power relations in the novels are also read, with reference to Michel Foucault. As the protagonists in two of them work as journalists, a critical discussion about media and Bourgeois hegemony is found; the term "repressive legitimation" is created to grasp these patterns of manipulation. The Modernist Debate , part II of the study, concerns a literary discussion between mainly Finland-Swedish authors and critics. Essayist Johannes Salminen (40) provided much of the fuel for the debate in 1963, questioning the relevance to contemporary life of the Finland-Swedish modernist tradition of the 1910 s and 1920 s. In 1965, a group of younger authors and critics, including poet Claes Andersson (28), followed up this critique in a debate taking place mainly in the newspaper Vasabladet. Poets Rabbe Enckell (62), Bo Carpelan (39) and others defended a timeless poetry. This debate is contextualized and the changing literary field is analyzed using concepts provided by sociologist Pierre Bourdieu. In the thesis, the historical moment of Middle Class radicalism with a human face is regarded a temporary luxury that new social groups could afford themselves, as long as they were knocking over the statues and symbols of the Old Bourgeoisie. This is not to say that all components of the Sixties strategy have lost their power. Some of them have survived and even grown, others remain latent in the gene bank of utopias, waiting for new moments of change.

Kognitiva system i namngivningen av finländska handelsfartyg 1838-1938

This dissertation is an onomastic study of Finland s stock of ship names (nautonomasticon) recorded over the period 1838 1938. The primary material investigated consists of 2 066 examples of ship names from the fleets of coastal towns, distributed over five sample years. The material is supplemented with two bodies of comparative data; one that consists of 2 535 examples of boat names from the archipelago area at the corresponding time, and another that comprises 482 examples of eighteenth century Finnish ship names. This study clarifies the categories of names that appear the frequency of the names, formation, morphology, linguistic origin, functions, and semantic qualities. By comparing the material with boat names from previous centuries, and from other countries, the characteristics of Finnish vessel names are further highlighted. Additional clarification is brought to the chronological, regional, and social variations, and to the emergence of various forms of systematic naming. This dissertation builds on older research from other countries, and uses traditional onomastic methods alongside a more modern methodology. The approach is interdisciplinary, meaning that the names are explored using facts not only from nautical history, but also from a range of other historical disciplines such as economics, culture, art, and literature. In addition, the approach is socio-onomastic, i.e. that the variations in names are studied in a societal context. Using a synchronised perspective, cognitive linguistic theories have provided the tools for this exploration into the metaphorical and the prototypical meaning of the names, and the semantic domains that the names create. The quantitative analysis has revealed the overall picture of Finnish boat names. Personal names, names from mythology, and place names, emerge as significant categories, alongside nonproprial names in Swedish and Finnish. The interdisciplinary perspective has made it possible to explain certain trends in the stock of boat names, for example, the predisposition towards names from classical mythology, the breakthrough of names taken from the national epos Kalevala, names in the Finnish language from around the middle of the nineteenth century, and the continuing rise of place names during the latter part of the period 1838 1938. The socio-onomastic perspective has also identified clear differences between those ship names used in towns, and those ship names used in the archipelago, and it has clarified how naming conventions tend to spread from town centres to peripheral areas. The cognitive linguistic methods have revealed that the greater part of the vessel names can be interpreted as metaphors, in particular personifications, and that many names are related in their content and also form semantic networks and cognitive systems. The results indicate that there is a mental nautonomasticon that consists of a standard set of traditional ship names, but they also reveal the existence of conscious or unconscious cognitive systems (rules and conventions) that guide the naming of boats.

Anpassning i språkkontakt : Morfologisk och ortografisk anpassning av engelska lånord i svenskan

The study investigates the formal integration of English loanwords into the Swedish language system. The aim has been to analyse and describe the morphological/morphosyntactic and the orthographical integration of the loanwords. I have studied how the foreign language elements get accommodated to Swedish and which factors are relevant in the integration. The material for the study consists of Swedish newspapers published in Sweden and Finland in paper format (with a focus on the years 1975 and 2000) and newspapers in digital format on the net. The theoretical frame for the study is contact linguistics. The study is based on a sociolinguistic, structural and language political perspective on what language is, and what language contact is. The method used is usage-based linguistic analysis. In the morphological study of the loanwords, I have made both a quantitative and a qualitative study. I have analysed the extent to which loanwords show some indication of integration in Swedish, and to what extent they show no signs of integration at all. I have also analysed integration in relation to word classes i.e., how nouns, adjectives and verbs integrate and which factors are relevant for the result of the integration. The result shows that most loanwords (36 %) do not show any signs of being formally integrated in Swedish. They undergo neither inflectional, nor derivational changes. One fifth of the loanwords are inflected according to the rules of Swedish grammar. Nouns are generally more often than verbs placed in positions in the sentence where no formal adaption is needed. Almost all of the verbs in the material are inflected according to Swedish rules of grammar. Only 3 % of the loanwords are inflected according to English rules or are placed in an ungrammatical position in the sentence. The orthographical study shows that English loanwords very seldom get adapted to Swedish orthography. Some English vowel and consonant graphemes are replaced with Swedish ones, for example a, ay and ai are replaced with aj or ej (mail → mejl). The study also indicates that morphological integration is related to orthographical integration: loanwords that are inflected according to Swedish grammar are more likely to be orthographical integrated than loanwords that are inflected according to English grammar. The results also shows that the integration of loanwords are affected by mostly language structural factors and language political factors.

Det pedagogiska självet : en narrativ studie av direktvalda svensklärarstudenters berättelser

The Pedagogical Self: a narrative study of stories by prospective subject teachers of Swedish The aim of this study is to examine how prospective subject teachers of Swedish experience themselves, their lives and their studies in university context. By answering this question I try to shed light on the pedagogical self of the students, i.e. to reach a deeper understanding of the narrative construction of their teacher identity. My material consists of stories written by one group of students and of transcribed interviews with another group of students at Nordica. All these students have entered both the teacher education programme and studies in their major subject simultaneously, through the so called direct admission. My study focuses on the students first year at the university. I define teacher identity, the pedagogical self, as the part of an individual s self-concept where he/she makes an assessment of himself/herself as a teacher(-to-be). The frame of reference of this interdisciplinary narrative study is founded on phenomenology, hermeneutics, social constructionism and dialogism. The main analysis of the stories is thematic, with the addition of linguistic and metaphorical analysis. With reference to the theories of Paul Ricoeur and Katharine Young, I regard the textual world of the stories as a world of its own. This implies that the researcher can feel free to concentrate on the texts, thus being able to leave the mental processes of the writers disregarded. The theoretician that has influenced my research the most is Max van Manen. He combines a pedagogical attitude with a phenomenological-hermeneutic philosophy. My research results imply that most of these students are drawn to studying Swedish by the clear professional orientation of the studies; their identity as teachers seems to be stronger than their identity as language teachers. The image of a teacher is relatively traditional: a teacher is seen as a self-evident authority, but at the same time as a fostering educator. The students see their studies in a larger perspective: studies as well as the future profession are only one part of life, albeit an important one. Keywords: narrativity, teacher identity
