” För tillfället så har jag inga elever med behov av differentiering” : differentiering i gymnastikundervisningen inom den grundläggande utbildningens årskurser 7–9

Differentiering i gymnastikundervisning är ett relativt outforskat område. I den nya läroplanen som tas i bruk höstterminen 2016 har begreppet differentiering fått en allt större betydelse. Enligt läroplanen innebär differentiering att läraren erbjuder elever exempelvis olika arbetssätt, tempo och grupper för att eleverna ska utvecklas enligt sina individuella förutsättningar. Speciellt inför byte av läroplan är det intressant att undersöka hur gymnastikundervisningen ser ut inom den grundläggande utbildningens årskurser 7–9. Syftet med avhandlingen är att undersöka hur gymnastiklärare planerar, genomför och utvärderar gymnastikundervisningen med avseende på differentiering i årskurserna 7–9 i finlandssvenska skolor. Utöver detta undersöks lärarnas kännedom om läroplanen samt andra faktorer som kan påverka differentieringen. Dessutom undersöks hur olika gymnastikgrenar enligt gymnastiklärarna inverkar på möjligheten till differentiering. Utgående från syftet har fyra forskningsfrågor formulerats: 1. Hur differentierar gymnastiklärarna gymnastikundervisningen? 2. Hur är gymnastiklärarnas kännedom om de nationella läroplanernas bestämmelser om en differentierad undervisning? 3. Hur är sambandet mellan skol- och läraranknutna faktorer och differentieringen i gymnastikundervisningen? 4. Hur ser gymnastiklärarna på sina möjligheter till differentiering i olika grenar? För att besvara frågeställningarna valdes en kvantitativ forskningsmetod i form av en webbenkät. Webbenkäten skickades ut åt 108 gymnastiklärare och 14 rektorer. På webbenkäten svarade 49 respondenter vars svar analyserades statistiskt. Majoriteten av gymnastiklärarna känner rätt bra eller i någon mån till differentiering. Av gymnastiklärarna anser 4 att alla elever i deras undervisning är i behov av differentiering. Gymnastiklärarna differentierar främst utvärderingen i gymnastikundervisningen. Själva genomförandet av undervisningen tenderar att differentieras minst. Skol- och läraranknutna faktorer påverkar inte differentieringen i gymnastikundervisningen. De grenar som gymnastiklärarna ansåg vara mest möjliga att differentiera var redskapsgymnastik, friidrott och bollspel.

Economic capital allocation

For my Licentiate thesis, I conducted research on risk measures. Continuing with this research, I now focus on capital allocation. In the proportional capital allocation principle, the choice of risk measure plays a very important part. In the chapters Introduction and Basic concepts, we introduce three definitions of economic capital, discuss the purpose of capital allocation, give different viewpoints of capital allocation and present an overview of relevant literature. Risk measures are defined and the concept of coherent risk measure is introduced. Examples of important risk measures are given, e. g., Value at Risk (VaR), Tail Value at Risk (TVaR). We also discuss the implications of dependence and review some important distributions. In the following chapter on Capital allocation we introduce different principles for allocating capital. We prefer to work with the proportional allocation method. In the following chapter, Capital allocation based on tails, we focus on insurance business lines with heavy-tailed loss distribution. To emphasize capital allocation based on tails, we define the following risk measures: Conditional Expectation, Upper Tail Covariance and Tail Covariance Premium Adjusted (TCPA). In the final chapter, called Illustrative case study, we simulate two sets of data with five insurance business lines using Normal copulas and Cauchy copulas. The proportional capital allocation is calculated using TCPA as risk measure. It is compared with the result when VaR is used as risk measure and with covariance capital allocation. In this thesis, it is emphasized that no single allocation principle is perfect for all purposes. When focusing on the tail of losses, the allocation based on TCPA is a good one, since TCPA in a sense includes features of TVaR and Tail covariance.

Synthesis and characterization of nanoperforated metal oxide thin films

For advanced devices in the application fields of data storage, solar cell and biosensing, one of the major challenges to achieve high efficiency is the fabrication of nanopatterned metal oxide surfaces. Such surfaces often require both precise structure at the nanometer scale and controllable patterned structure at the macro scale. Nowadays, the dominating candidates to fabricate nanopatterned surfaces are the lithographic technique and block-copolymer masks, most of which are unfortunately costly and inefficient. An alternative bottom-up approach, which involves organic/inorganic self-assembly and dip-coating deposition, has been studied intensively in recent years and has proven to be an effective technique for the fabrication of nanoperforated metal oxide thin films. The overall objective of this work was to optimize the synthesis conditions of nanoperforated TiO2 (NP-TiO2) thin films, especially to be compatible with mixed metal oxide systems. Another goal was to develop fabrication and processing of NP-TiO2 thin films towards largescale production and seek new applications for solar cells and biosensing. Besides the traditional dip-coating and drop-casting methods, inkjet printing was used to prepare thin films of metal oxides, with the advantage of depositing the ink onto target areas, further enabling cost-effective fabrication of micro-patterned nanoperforated metal oxide thin films. The films were characterized by water contact angle determination, Atomic Force Microscopy, Scanning Electron Microscopy, X-ray Photoelectron Spectroscopy and Grazing Incidence XRay Diffraction. In this study, well-ordered zinc titanate nanoperforated thin films with different Zn/Ti ratios were produced successfully with zinc precursor content up to 50 mol%, and the dominating phase was Zn2Ti3O8. NP-TiO2 structures were also obtained by a cost-efficient means, namely inkjet printing, at both ambient temperature and 60 °C. To further explore new biosensing applications of nanoperforated oxide thin films, inkjet printing was used for the fabrication of both continuous and patterned polymeric films onto NP-TiO2 and perfluorinated phosphate functionalized NP-TiO2 substrates, respectively. The NP-TiO2 films can be also functionalized with a fluoroalkylsilane, resulting in hydrophobic surfaces on both titania and silica. The surface energy contrast in the nanoperforations can be tuned by irradiating the films with UV light, which provides ideal model systems for wettability studies.

Building climate justice : an analysis of how the nexus between climate change and human rights shapes public policy agendas and alternatives

This thesis provides an analysis of how the nexus between climate change and human rights shapes public policy agendas and alternatives. It draws upon seminal work conducted by John Kingdon, whose landmark publication “Agendas, alternatives, and public policy” described how separate streams of problems, solutions, and politics converge to move an issue onto the public policy agenda toward potential government action. Building on Kingdon’s framework, this research explores how human rights contribute to surfacing the problem of climate change; developing alternative approaches to tackling climate change; and improving the political environment necessary for addressing climate change with sufficient ambition. The study reveals that climate change undermines the realization of human rights and that human rights can be effective tools in building climate resilience. This analysis was developed using a mixed methods approach and drawing upon substantial literature review, the researcher’s own participation in international climate policy design; elite interviews with thought leaders dealing with climate change and human rights; and regular inputs from focus groups comprised of practitioners drawn from the fields of climate change, development and human rights. This is a journal based thesis with a total of six articles submitted for evaluation, published in peer‐reviewed publications, over a five year period. Denna avhandling analyserar hur klimatfrågan och mänskliga rättigheter i samverkan formar den politiska agendan och det politiskt möjliga. Den bygger på banbrytande forskning av John Kingdon, vars publikation “Agendas, alternatives, and public policy” beskriver hur en fråga blir politiskt viktig och lyfts upp på den politiska agendan. Med utgångspunkt i Kingdons ramverk, utforskar avhandlingen hur mänskliga rättigheter bidrar till att blottlägga klimatfrågan som problem; utveckla alternativa metoder för att angripa och hantera klimatfrågan; samt skapa ett politiskt klimat nödvändigt för att på ett ambitiöst sätt kunna angripa klimatfrågan. Studien visar att klimatförändringar undergräver mänskliga rättigheterna men att arbete med mänskliga rättigheter kan vara ett effektivt verktyg för att stå emot och hantera effekterna av klimatförändringar. Analysen har genomförts med hjälp av en rad olika metoder vilka inkluderar litteraturstudier, författarens egna observationer under klimatförhandlingar; intervjuer med ledande tänkare inom klimatfrågan och mänskliga rättigheter; samt data insamlad genom fokusgrupper bestående av yrkesverksamma inom klimat, utveckling och mänskliga rättigheter. Avhandlingen är baserad på totalt sex artiklar som publicerats i fackgranskade tidskrifter under en femårsperiod.

Grammatikdidaktik: Svensk grammatik och språklig medvetenhet i några läromedel för grundskolans första årskurser

Mitt övergripande forskningsintresse är grammatikdidaktik, medan det explicita syftet med denna licentiatavhandling är att erhålla ny kunskap om grammatikdidaktik så som den synliggörs i nutida läromedel för grundskolans första årskurser. Den empiriska undersökningen är gjord i tre nutida läromedelspaket avsedda för undervisning i skolämnet modersmål och litteratur i årskurs ett och två, läromedlen som undersöks är de finlandssvenska serierna Läseboken och Litteraturboken samt den sverigesvenska serien Kom och läs! Bland resultaten kan nämnas att det finns ett brett spektrum av nivåer av extern grammatik i alla de undersökta läromedelspaketen. Den fonologiska och syntaktiska medvetenheten, vilka bägge är viktiga för läs- och skrivutvecklingen i de diskuterade årskurserna, satsas på i alla tre läromedelspaket. Det jag dock också märkt i läromedlen som kan påverka läs- och skrivutvecklingen är att andelen belägg för grafonomi är större i årskurs två än i årskurs ett. Härigenom får eleverna på detta sätt småningom växa in i en skriftkultur. Det finns betydligt fler muntliga uppgifter i lärarhandledningarna till serierna Litteraturboken och Kom och läs! än i Läseboken. Det exakta ”hur” står inte alltid utskrivet i lärarhandledningarna, men de flesta gånger verkar tanken vara att det rör sig om diskussioner eller andra muntliga genrer. I många fall känns de muntliga uppgifterna mer funktionella än skriftliga uppgifter som inte verkar vara helt genomtänkta. Att mitt material innehåller fler funktionella uppgifter i lärarhandledningar och fler formalistiska eller delvis funktionella uppgifter i arbetsböcker överensstämmer med att lärarhandledningar kan vara en bättre väg för att öka elevernas kunskapssökande och minska förmedlingspedagogiken.

Människans liv med sömnbesvär och hur människor med sömnbesvär upplever kognitiv beteendeterapi

Sleep disorders are a common health problem in western countries. Every third working age person suffers from sleep deprivation and that often leads to other health problems as well. One can end up in a vicious circle, which can further decrease mood and ability to function. The aim of this thesis is to illustrate how sleep deprivation affects the lives of working age population and to deepen our understanding of life with sleep deprivation. Study questions are: how does sleep deprivation affect a working age person’s life and what kind of experiences do people have about cognitive-behavioural therapy as a treatment to sleep disorders. Theoretical perspective is based on clinical nursing science theories and the humanist view of man, which sees human as an entity. The methodology used is phenomenological approach and data analysis is conducted by using Ricœur’s hermeneutic phenomenological interpretation method. The empirical part is divided into two different sections. The material of the study consists of interviews and surveys done by people who have experienced sleep deprivation or sleep disorders. Two interviewees talked about their lives with sleep disorders and there are 21 surveys conducted on people’s experiences on cognitive-behavioural therapy. The partakers in the two sections are different people. The results show that people with sleep disorders can end up in a vicious circle of sleep deprivation and in worst cases a sleep disorder can take charge of a person’s whole life. Sleep disorder can cause shame and fear of stigma. Nevertheless, someone suffering from a sleep disorder can find strength and solutions to control the difficult situation. This study proves that both nursing staff and other people have little information about difficulties in sleeping and awareness should be improved in clinical nursing. A health-care provider has an essential role in preventing someone ending up in a vicious circle of sleep deprivation and cognitive-behavioural therapy can contribute to good health. Reflection at the end of cognitive-behavioural sleep therapy course helps patients to continue their learning process. When someone is sleep deprived, it means that they have control over the situation, but when someone has a sleep disorder, that person does not have the strength to control the situation.

Den Äldsta – livet är ett tillägnande : en vårdvetenskaplig explorativ studie av ett meningsbärande budskap och en innerlig visdom

In the background of the thematic The Eldest – life is acquiring one finds both previews and myths. Wisdom belongs to these myths. The hermeneutical philosophy refers to thinking as o movement from myth to logos in a dialogical oneness. The research uncovers dimensions in the element wisdom as empowered. The experiences of older are saved for further learning and transformation to younger with reference to vulnerable situations where common regulations are no more usefull. The interest goes to an Eldest. The Eldest in the study is pictorial in accordance to the main literature in the study.The Eldest is etymological, fictive and symbolic: – a man who understands higher matters of life, even Gods holy matters. She will set the fulfillment of others as the highest endowment out of an innermost ethos and an innermost wisdom. The innermost is wisdom. The aim is to discover a meaningful message in life is acquiring. In order to see and to learn from the experiences the study aim to uncover the innermost, an innermost wisdom out of a caritative approach. This innermost is anticipated as a longing for unity and health in dayly matters and in a caring ability for the other. The main overstatement is: What will this most meaningfull and innermost by the Eldest out of a living in factual life mirrored in a caring perspective be? Two questions expired; what will the meaningful message in the acquiring be? What will the innermost wisdom in serving the good be? This message and its innermost wisdom will get an expanded meaning out of a caring sentence: Man who dare – seeing back with gratitude, seeing forward in confidence, seeing aside with love and upward in fate wear that dignity, that holiness and that mercy and empathy which belong to life in its basics. The persons attending the research are situated in two contexts. One group has roots in the Lutheran church and the other in a caring profession. The datamaterial is formed out of the usages from these persons, from the spoken (conversation) and the written word (a guestbook). The usages as particular and common are continually integrated in the leading caring sentence from the beginning of the study to the end. The usages stand by the methodological for the final message and wisdom and at the same they form the operative dimension in the study, the evident and the validity. The overarching methodological approach is in the hermeneutic philosophy in accordance with the abductive logic. The usages out of two research groups are most significant in this deductive, inductive and abductive strategy. The usages from the research groups are confronted with the caring sentence in dialogical spaces, halts. The meaning and the innermost searched for will be pictured through the abductive and hermeneutic interpretation and will stand for an articulation of and a successively expansion of meaning. A twine of horizons out of the entire dissemination, the deductive and the inductive, creates the result, as the final message as the ground for an understanding of an even more embracing meaning in an innermost wisdom. The identified bearing movement in the groups in accordance with the caring sentence goes for something higher, something higher than me, to the wellbeing of the other. A conclusion is made and a thesis is identified. This thesis is out from the usages: What can I do in a creating of this caritative? An antithesis is also identified, is a man able to look outside one own and go to something higher, something greater? The synthesis is articulated as a dialogical movement from something … to something higher. The bridge could be maturation, transcendence, the divine or wisdom. The statement finds its root in the attending groups but a difference is also identified. This higher matter is different. The contexts and their meaningfulness decide. A final statement is: learn to see man and her matters hold in life.

JNK regulation of neurogenesis, neuroplasticity and anxiety-related behaviors in mice

I vår moderna värld har förekomsten av ångeststörningar drastiskt ökat, vilket påverkar välfärden i våra samhällen. Eftersom de molekylära mekanismerna bakom ångest är relativt okända, är möjligheterna till behandling av ångeststörningar begränsade. I och med utvecklingen av genetiska manipuleringmetoder och avbildningstekniker har strukturella förändringar associerade med ångeststörningar kunnat konstateras. Neuroanatomiska studier har påvisat störningar i dendritarkitektur, dendrittaggar och i neurogenesen hos vuxna individer. Särskilt neurogenesen i hippocampus anses viktig i detta sammanhang. Neurogenes i hippocampus har föreslagits spela en viktig roll i ångeststörningarnas patofysiologi och för hur vissa antidepressiva läkemedel förmedlar sin effekt. Under senare år har MAP-kinaser (MAPK) föreslagits vara involverade både i uppkomsten av affektiva störningar och i neurogenes i hippocampus. JNK är en grupp kinaser inom MAPK-familjen som aktiveras av olika externa stressfaktorer. I normala celler är aktiviteten hos JNK låg. Cell-stress ökar aktiviteten hos JNK vilket leder till bl.a. apoptos. JNK kinaser anses vara potentiella terapeutiska mål för behandling av neurodegenerativa sjukdomar men deras potential som mål för behandling av affektiva sjukdomar har tillsvidare inte utretts. Den här avhandlingen behandlar betydelsen av JNK för ångestrelaterat beteende hos möss. Med hjälp av Jnk1-knockout möss och farmakologisk inhibering av JNK-signalering, demonstreras att JNK reglerar neurogenes i hippocampus, vilket i sin tur ligger bakom mössens ångestrelaterade beteende. Jnk1-knockout möss var mindre ängsliga och uppvisade ökad neurogenes i hippcampus jämfört med kontrollmöss. Inhibering av JNK-signalering i hjärnan hos möss gjorde dem också mindre ängsliga och ökade neurogenesen i hippocampus på samma sätt som vissa antidepressiva läkemedel. Inhibering av JNK-aktivitet ledde inte bara till ökad neurogenes i hippocampus, utan främjade också mognandet av nybildade nervceller hos vuxna möss. Resultaten visar också att dendritarkitekturen och fördelningen av dendrittaggar hos CA3 neuroner i hippocampus är förändrad hos Jnk1-knockout möss. Genom screening av substratmolekyler för JNK hittades två JNKeffektormolekyler, MARCKSL1 (ett aktin-associerat protein) och MAP2 (ett mikrotubulus-associerat protein), som reglerade neuronernas sttruktur. Det här tyder på att JNK-signalering kan kontrollera ångeststörningsrelaterade förändringar hor dendriter och dendrittaggar. Sammanfattningsvis ger resultaten som presenteras i avhandlingen en ökad insikt i molekylära mekanismer som kan leda till ångeststörningsrelaterade förändringar i neurogenes och dendritstruktur. Därtill föreslås att JNKsignalbanan har potential som terapeutiskt mål för behandling av ångeststörningar.

Pourquoi le français ? : les moyens à la disposition des professeurs de français pour inciter les élèves finlandais à choisir le français à l’école

Utgångspunkten för pro gradu-avhandlingen är det sjunkande intresset för att läsa franska bland finländska grundskole- och gymnasieelever. Trenden är oroväckande, inte minst för franskans framtid i Finland, för fransklärare och nyutexaminerade, men även mer generellt för landets språkkapital och konkurrenskraft i en allt mer globaliserad värld. Syftet med den här avhandlingen är att undersöka vilka medel franskläraren kan använda sig av för att uppmuntra elever att välja franska i skolan. Jag har valt att undersöka lärarens syn på språkval, delvis för att tidigare forskning i motivation för inlärning av främmande språk främst gjorts utifrån elevens synvinkel och delvis för att studier visar att läraren har en stor inverkan på elevernas språkval. Avhandlingen består av två kompletterande empiriska delar. I den första studeras argument som framförs i de mest använda materialen för marknadsföring av franska i skolor. Argumenten analyseras främst ur ett motivationsperspektiv enligt Czisérs och Dörnyeis (2005) modell för intern struktur av motivation för språkinlärning. Den andra delen av studien baserar sig på en elektronisk enkät som konstruerats för forskningssyftet. Enkäten riktar sig till fransklärare i Finland på grundskole- och gymnasienivå. Svarsprocenten på enkäten är 21%. Enkätsvaren belyser vilka argument och metoder som används för marknadsföring av franska i skolan. Svaren studeras både kvalitativt och kvantitativt. I analysen har Czisér och Dörnyeis (2005) teorier och en modell av Kangasvieri et al. (2011) för motivation för språkval i Finland tillämpats. Resultaten bekräftar att de argument som tillämpas mest är instrumentella. De här argumenten borde trots det utvecklas och användas i större grad. I marknadsföringen borde man även sikta på att förmedla en positiv bild av studier i franska och av målspråket samt tala för nyttan av att kunna franska i sig. Bland de olika metoderna är informationsmöten det populäraste sättet att marknadsföra språket på varje stadium. Tillämpningen av övriga metoder varierar enligt stadium och skola. Majoriteten av deltagarna anser att marknadsföring av franska är viktigt, men betraktar utvecklingen av undervisningen som det bästa sättet att locka fler studerande att välja franska. I enlighet med tidigare forskning påvisar den här avhandlingen nyttan och behovet av marknadsföring av franska vid språkval. Läraren spelar en viktig roll i målet att uppmuntra fler elever att välja franska i skolan. Förutom lärarna deltar skolan, institutionerna och näringslivet i utformandet av attityder gentemot undervisning och inlärning av främmande språk i det finska samhället och således även gentemot valet av franska som läroämne.

Utstillingens retorikk : et bidrag til en retorisk didaktikk for kunst og håndverk

The topic of this dissertation is the didactic exhibition in the Arts and Crafts subject. Exhibiting student work and art and form culture is part of a long professional tradition in the field. Yet, exhibition as form and as a way of learning are inadequately explored and debated. The didactic problem area of the thesis, where studies of formative practices are central, place it within the research field of Educational Slojd. The didactic standpoint and main theoretical perspective relate the project to the Arts didactics research field at the University College of Bergen where the aim is to develop an alternative didactics thinking for the arts; a rhetoric arts didactics. Didactic focus is shifted from the relationship between teacher – pupil – teaching materials, to studies of how knowledge is formulated in specific practices. The thesis has a premise that every exhibition has its own rhetoric and that didactics is inscribed in this rhetoric in the broadest and cultural sense. Through impulses from classical rhetoric and recent text theory, the thesis challenges the Arts and Crafts’s own idiom, its theoretical foundation and didactic grasp such as shown in the discourse established by the discipline and its specific exhibitive practices, as well as studying the relationship between verbal language and the discipline’s own register. The overall objective is to develop knowledge about exhibition rhetoric and its potential as a knowledge and learning arena in this field, and thereby contribute to developing a rhetoric didactics for the Arts and Crafts subject. This raises questions such as: How is an exhibition considered to be used and understood in the subject’s didactics texts and texts about didactics? How do different exhibition spaces inscribe conditions for exhibition work? How can a rhetoric perspective of didactics make aspects of an exhibition’s form register visible and contribute to knowledge of the creative processes in an exhibition? How do some selected exhibitions inscribe creativity and learning? What can a rhetoric perspective bring to the Arts and Crafts? A rhetoric didactics perspective includes knowledge of the tradition. A historical-ideological overview traces how exhibition, of both pupil/student work and of art and form culture, are used and considered as used in the discipline over time. This part can be read separately, but in this thesis, is primarily conceived as a backdrop for the development of the dissertation’s main rhetoric perspective. The empirical data are collected from my teacher training institution and consist of specific exhibition spaces and practices, of which my own production of two exhibitions can link the research to artistic development work. A rhetoric didactics is concrete, specific and contextual. The rhetoric readings are descriptive and show how culture and nature, temporality, materiality and technology are inscribed in the exhibition’s form. Didactic reflection develops from, and close to, the rhetoric readings of the exhibition’s form and content to finally arrive at a rhetorical concept for creativity and learning.

Novel cancer-related regulatory targets for the signalling sphingolipids sphingosine-1-phosphate and sphingosylphosphorylcholine

The signalling sphingolipid sphingosine-1-phosphate (S1P) is necessary for development of the immune system and vasculature and on a cellular level regulates migration, proliferation and survival. Due to these traits S1P has an important role in cancer biology. It is considered a primarily cancer-promoting factor and the enzyme which produces it, sphingosine kinase (SphK), is often over-expressed in tumours. S1P is naturally present in the blood, lymph, tissue fluids and cell cytoplasm and functions through its cell surface receptors (S1P1-5) and as an intracellular second messenger. Sphingosylphosphorylcholine (SPC) is closely related to S1P and has similar regulatory functions but has not been extensively studied. Both S1P and SPC are able to evoke either stimulatory or inhibitory effects on cancer cells depending on the context. The aim of this thesis work was to study novel regulatory targets of S1P and SPC, which mediate the effects of S1P/SPC signalling on cancer cell behaviour. The investigated targets are the transcription factor hypoxia-inducible factor 1 (HIF-1), the intermediate filament protein vimentin and components of the Hippo signalling pathway. HIF-1 has a central role in cancer biology, as it regulates a multitude of cancer-related genes and is potently activated by intratumoural hypoxia through stabilization of the regulatory subunit HIF-1α. Tumours typically harbour high HIF-1α levels and HIF-1, in turn, facilitates tumour angiogenesis and metastasis and regulates cancer cell metabolism. We found S1P to induce follicular thyroid cancer cell migration in normal oxygen conditions by increasing HIF-1α synthesis and stability and subsequently HIF-1 activity. Vimentin is a central regulator of cell motility and is also commonly over-expressed in cancers. Vimentin filaments form a cytoskeletal network in mesenchymal cells as well as epithelial cancer cells which have gone through epithelial-mesenchymal transition (EMT). Vimentin is heavily involved in cancer cell invasion and gives tumours metastatic potential. We saw both S1P and SPC induce phosphorylation of vimentin monomers and reorganization of the vimentin filament network in breast and anaplastic thyroid cancer cells. We also found vimentin to mediate the anti-migratory effect of S1P/SPC on these cells. The Hippo pathway is a novel signalling cascade which controls cancer-related processes such as cellular proliferation and survival in response to various extracellular signals. The core of the pathway consists of the transcriptional regulators YAP and TAZ, which activate predominantly cancer-promoting genes, and the tumour suppressive kinases Lats1 and Lats2 which inhibit YAP/TAZ. Increased YAP expression and activity has been reported for a wide variety of cancers. We found SPC to regulate Hippo signalling in breast cancer cells in a two-fold manner through effects on phosphorylation status, activity and/or expression of YAP and Lats2. In conclusion, this thesis reveals new details of the signalling function of S1P and SPC and regulation of the central oncogenic factors HIF-1 and vimentin as well as the novel cancer-related pathway Hippo.

In search of good relationships to music : understanding aspiration and challenge in developing music school teacher practices

This study focuses on teacher practices in publicly funded music schools in Finland. As views on the aims of music education change and broaden, music schools across Europe share the challenge of developing their activities in response. In public and scholarly debate, there have been calls for increased diversity of contents and concepts of teaching. In Finland, the official national curriculum for state-funded music schools builds on the ideal that teaching and learning should create conditions which promote ‘a good relationship to music’. The meaning of this concept has been deliberately left open in order to leave room for dialogue, flexibility, and teacher autonomy. Since what is meant by ‘good’ is not defined in advance, the notion of ‘improving’ practices is also open to discussion. The purpose of the study is to examine these issues from teachers’ point of view by asking what music school teachers aim to accomplish as they develop their practices. Methodologically, the study introduces a suggestion for building empirical research on Alperson’s ‘robust’ praxial approach to music education, a philosophical theory which is strongly committed to practitioner perspectives and musical diversity. A systematic method for analysing music education practices, interpretive practice analysis, is elaborated with support from interpretive research methods originally used in policy analysis. In addition, the research design shows how reflecting conversations (a collaborative approach well-known in Nordic social work) can be fruitfully applied in interpretive research and combined with teacher inquiry. Data have been generated in a collaborative project involving five experienced music school teachers and the researcher. The empirical material includes transcripts from group conversations, data from teacher inquiry conducted within the project, and transcripts from follow-up interviews. The teachers’ aspirations can be understood as strivings to reinforce the connection between musical practices and various forms of human flourishing such that music and flourishing can sustain each other. Examples from their practices show how the word ‘good’ receives its meaning in context. Central among the teachers’ concerns is their hope that students develop a free and sustainable interest in music, often described as inspiration. I propose that ‘good relationships to music’ and ‘inspiration’ can be understood as philosophical mediators which support the transition from an indeterminate ‘interest in music’ towards specific ways in which music can become a (co-)constitutive part of living well in each person’s particular circumstances. Different musical practices emphasise different aspects of what is considered important in music and in human life. Music school teachers consciously balance between a variety of such values. They also make efforts to resist pressure which might threaten the goods they think are most important. Such goods include joy, participation, perseverance, solid musical skills related to specific practices, and a strong sense of vitality. The insights from this study suggest that when teachers are able to create inspiration, they seem to do so by performing complex work which combines musical and educational aims and makes general positive contributions to their students’ lives. Ensuring that teaching and learning in music schools remain as constructive and meaningful as possible for both students and teachers is a demanding task. The study indicates that collaborative, reflective and interdisciplinary work may be helpful as support for development processes on both individual and collective levels of music school teacher practices.

Analyse de l'emploi de cependant

Ordet cependant översätts till ‘emellertid’ eller ‘dock’ på svenska. Men vad betyder ordet och hur används det? Denna fråga utgör den viktigaste forskningsfrågan för pro gradu-avhandlingen. De franska ordböckerna Le Petit Robert (2015), Larousse (2015) och Le Trésor de la langue francaise (2015) definierar att cependant uttrycker motsättning. Studier av ordets historiska utveckling visar ändå att cependant har använts i forn- och medelfranskan för att uttrycka två processers samtidighet (Marchello-Nizia 2007). Den här föråldrade betydelsen kan ännu hittas i litterära sammanhang. I avhandlingen analyseras cependant med hjälp av en korpus bestående av 150 textavsnitt som har samlats från tre olika källor i september och oktober 2014: 50 avsnitt från textdatabasen Frantext, 50 från dagstidningen Le Monde och 50 från Europaparlamentets förhandlingsreferat. I alla avsnitt används cependant. Textavsnitten studeras i samband med teorier som behandlar ordets betydelse: ordets kategoriseringar samt dess roll i skapandet av koncessivitet och polyfoni. Ytterligare studeras ordets placering i texten. Cependant kategoriseras som adverb, konnektiv och diskursmarkör. Alla dessa benämningar beskriver ordet från olika synvinklar: adverb anger ordets grammatiska ordklass, konnektiv beskriver ordets funktion som ett förbindande element mellan ord och meningar, och diskursmarkör betecknar ordets roll i interaktionell analys. I avhandlingen studeras på vilket sätt cependant uttrycker koncessivitet med hjälp av Morels (1996) definitioner och koncessivitetstyper. Analysen visar att koncessivitet egentligen inte kan delas in i olika typer. Istället är dess mest grundläggande egenskap den latenta relationen där två kontroversiella processer samordnas för att antyda den naturliga relationen mellan de ickekontroversiella processerna. Ordets sätt att uttrycka polyfoni studeras med hjälp av olika polyfoniteorier. Genom att göra en kvalitativ analys på min korpus kom jag fram till att det mest passande sättet att studera cependant ur ett polyfoniskt perspektiv är att analysera de olika synpunkter som uttrycks i en text (ett sätt som beskrivs i Nølke et al. 2004). Studien visar att cependant används på olika sätt i olika textgenrer och att ordet uttrycker både koncessivitet och polyfoni. Dessutom indikerar analysen att koncessivitet kan uppfattas som ett polyfoniskt fenomen.
