Sand, småbarn och intra-aktiv lek

Emilsson, Inga-Lill January 2011 (has links)
I förskolans utemiljö är det vanligt att det finns en sandlåda på gården. Den är centralt placerad och barnen är där och leker. Enligt den nya Skollagen och förskolans reviderade läroplan ska verksamhetens innehåll vila på vetenskaplig grund och beprövad erfarenhet. Detta gäller även den verksamhet som pågår i sandlådan. Men vad är det som sker när sanden, barnen och lekredskapen möts i sandlådan? Detta är en kvalitativ studie som utifrån ett intra-aktivt perspektiv syftar till att synliggöra hur sanden i sandlådan, lekredskap och de yngsta barnen (1-3 år) skapar möjligheter och villkor för lek och meningsskapande. Utifrån fotografier, anteckningar och videofilm har nya begrepp skapats för att kunna beskriva och förklara det som sker i sandlådan. Resultaten visar på en ständig rörelse där sand, barn och lekredskap förflyttas, förändras och förvandlas. Barn, sand och lekredskap leker tillsammans i ömsesidiga och sammanvävda intra-aktioner. Studiens resultat bidrar till att visa på dessa komplexa processer och hur små barn, med hela sin kropp och alla sinnen, medvetet tillsammans med sanden och lekredskapen skapar ny mening och nya möjligheter. / In the preschool outdoor environment, it is common that there is a sandbox. It is centrally located and the children are there and play. According to the new Education act and Curriculum for the Preschool Lpfö 98 (Revised 2010) the content should be based on scientific evidence and proven experience. This also applies to the activities being performed in the sandbox. But what is happening in the sand, when the children and play equipment come together in the sandbox? This is a qualitative study based on an intra-active perspective, whose purpose is to visualize how the sand in the sandbox, the playground equipment and the youngest children (1-3 years) create opportunities and conditions for play and meaning. Based on photographs, notes and video, new concepts are created to describe and explain what happens in the sandbox. The results show a continuous movement in which sand, children, and playground equipment is moved, changed and transformed. Children, sand and playground equipment play together in mutual and intertwined intra-actions. The findings in the study help to demonstrate how these complex processes and young children, with the whole body and the senses, consciously together with the sand and play equipment create new meaning and new possibilities.

"Nyss så träffa jag en krokodil, som körde runt i en bil" : Små barns kompetenser i ämnet biologi / "Just now I meet a crocodile, who was driving around in a car" : Toddlers competences in the subject of biology

Almgren Damberg, Ingrid January 2015 (has links)
The purpose of the study is to show young children's competences in the subject of biology. I hope that my work will lead to that the subject of biology is used more often in the preschool context. In my work I have had an intra-active theory as a base. I have searched for what children are interested in on the subject of biology. Here, I can conclude that animals and plants are major interests for the children. Furthermore, I wanted to explore the ways in which children's knowledge became visible. For the most part, small children (along with educators) use animism and anthropomorphism, however, this is often interwoven with facts. I also wanted to know whether there were factors that contributed to children's learning in biology. It became clear that factors such as outdoor stay and live animals and plants contributed to a fact-based learning in biology. In contrast, factors such as indoor stay and toys were important factors for an animistic and anthropomorphic learning in biology. Educators also have a crucial role in children's learning in biology. Through an intra-active approach, I note that both the factual events of biology and animism and anthropomorphism contribute to the child's creation of knowledge in biology. / Syftet med studien är att visa upp små barns kompetenser i ämnet biologi. Jag hoppas att mitt bidrag leder till att fler förskollärare lockas att arbeta med biologi. Jag har utgått från en intra-aktiv teori och praktik både i förarbetet, under mina observationer och samtal samt i analysprocess och diskussion. Jag har sökt efter vad barn väljer att leka och samtala om inom ämnet biologi. Här kan jag konstatera att djur och växter är ett stort intresse för barnen. Vidare ville jag undersöka på vilka sätt som barnens kunskaper blev synliga. Till största del använder sig små barn (tillsammans med pedagoger) av animism och antropomorfism däremot är detta ofta sammanvävt med fakta. Jag ville också veta om det fanns faktorer som bidrog till barns lärande i biologi. Här blev det tydligt att faktorer som utomhusvistelse och levande djur och växter bidrog till ett faktabaserat lärande i biologi. Däremot var faktorer som inomhusvistelse och leksakslek viktiga för ett animistiskt och antropomorfistiskt lärande i biologi. Pedagogerna har också en avgörande roll för barnens lärande i biologi. Genom ett intra-aktivt synsätt kan jag konstatera att både de faktabaserade biologihändelserna och de animistiska och antropomorfistiska biologihändelserna bidrar till barns kunskapande i biologi.

Curriculum and intra-dialogic spaces: consciousness and becoming in identity construction based on human rights values / J.A. Becker

Becker, Josephine Annie January 2013 (has links)
The growing marketisation of education has resulted in curriculum being conceptualised as a predesigned means to an end. Many South African scholars such as Jansen, (1999, 2009, 2011) and Du Preez (2009, 2011, 2012) have critiqued the instrumental nature of the post-apartheid curriculum and pleaded for an ethical perspective on curriculum conceptualisation that would encourage the construction of dialogic spaces in curriculum. This study questions technical and critical approaches to curriculum conceptualisation and advocates a reflexive conceptualisation of curriculum, intra-dialogue, identity construction, consciousness, becoming and human rights values within an ethical perspective to curriculum conceptualisation in the post-structural paradigm. The central theme of this reflexive reconceptualisation is the hope of continual revolutionary new beginnings by which identity construction (who we are) and the realisation of human rights values in the ethical relation self:other can be re-imagined. This hope has also been central to the (re)structuring of the post-apartheid curriculum premised on the values of The South African Constitution and Bill of Rights (1996). Curriculum, structured within a predesigned market-related and instrumental approach to curriculum, can however not aid identity construction, re-imagine a new society or realise human rights values. A new society is re-imagined between teacher:child, disrupting how and what they know of self:other and re-imagining new ways of knowing and being with self:other rooted in human rights values. The conditions for intra-dialogue, namely the ethical relation self:other and spaces of togetherness, are also interrelated elements in intra-dialogic curriculum spaces. The ethical relation teacher:child roots intra-dialogic curriculum spaces in human rights values and the consciousness of responsibility for self:other. Spaces of togetherness situate teacher:child in specific and non-linear space and time in which they narrate their different life experiences from which identity is constructed. Intra-dialogue is the disruptive, revolutionary and intentional action between self:other as simultaneously singular in equal difference and together in a shared humanity. Human rights values are dialogic, relational and revolutionary in nature. Human rights values are realised when teacher:child within intra-dialogic curriculum spaces premised on equal difference, freely confess autobiography and continually (re)construct identity and the relation self:other. In equal difference teacher:child are received and defined as someone – unique, dignified and irreplaceable. As equal and irreplaceable partners teacher:child disrupt, deconstruct and re-imagine the ethical relation self:other. Within intra-dialogic curriculum spaces, teacher:child can reclaim the revolutionary capacity of curriculum and revolutionise self, self:other, education and society in continual becoming. / Thesis (PhD (Curriculum Development Innovation and Evaluation))--North-West University, Potchefstroom Campus, 2013

Macedonia 1991-2001: a case-study of conflict prevention - lessons learned and broader theoretical implications

Ripiloski, Sasho, sash1982@optusnet.com.au January 2009 (has links)
Notwithstanding a broad range of internal and external stresses, Macedonia was the only republic to attain its independence peacefully from the otherwise violent disintegration of the former Yugoslavia in the early 1990s. Subject of a timely and sustained international response, it was feted as a rare preventive success for the international community. Whilst not necessarily decisive, this mobilisation helped ensure a non-violent transition to independence. Yet, much to the surprise of outside observers, Macedonia would fall into conflict a decade after independence, when self-styled freedom fighters purporting to represent the local Albanian community launched an eight-month insurgency in the name of political and cultural equality. Triggered by a coalescence of political, nationalist, ideological and criminal interests, the insurgency had complex roots, as much an intra-Albanian putsch as a struggle for greater group rights. Regardless of their precise genesis, from the perspective of conflict prevention, the events of 2001 challenge popular assumptions of Macedonia as an international success story. Above all, they reinforce the need for external actors to incorporate short-term strategies of prevention targeting immediate sources of instability within a more comprehensive, long-term framework that addresses structural, underlying conflict causes. Indeed, whilst proximate threats to Macedonian stability were addressed, fundamental risk factors remained, namely social polarisation, a large ethnic minority disenfranchised with the state, economic under-development, high levels of organised crime and corruption, a weak rule-of-law and continuing regional uncertainty. These were partly aggravated by the mistakes of a complacent international community, whose engagement in the country, accordingly, receded over time. In particular, the dissertation is critical of the European Union for its initial failure to articulate a genuine pathway to membership for Macedonia and the broader western Balkans, as well as the handling of NATO's military intervention in neighbouring Kosovo. Of course, in any preventive endeavour, the international community can only do so much; in the first instance, responsibility lay with unresponsive Macedonian institutions, who failed to adequately address legitime Albanian demands dating from independence. Be that as it may, the international community was culpable for its failure to sufficiently apply the formidable soft-power leverage it wields over a weak Macedonian state to implement reforms that, conceivably, could have precluded the outbreak of armed conflict. As a case-study of prevention, Macedonia holds instructive lessons for scholars and policymakers. Yet it remains under-researched. Examining the period 1991-2001, this investigation analyses precisely why and how Macedonia avoided violence during the process of Yugoslav dissolution yet ultimately fell into conflict, and extrapolates broader lessons that may be applied to other at-risk societies. Its purpose is to advance understanding of a poorly understood country, and contribute knowledge to key on-going international security debates. Highlighting the inter-connectedness and trans-national character of contemporary security threats, it posits that the major powers have a practical interest in addressing emerging intra-state crises, even when the putative national interest appears marginal. To facilitate more timely multilateral responses, it calls for the de-nationalisation of security, and its conceptualisation in international - as opposed to strictly national - terms.

Intra-aktionen mellan natur, kultur, och teknik i den fotografiska processen

Idberg, Oscar January 2018 (has links)
En djupdykning i att forska inom filosofin som är posthumanismen har utförts för att se hur den kan appliceras på den fotografiska processen. Flera aspekter av posthumanismen har identifierats som sedan har gjort ett försök till att skapa en alternativ metod för att få ett fotografi att uppstå. Några av de största svagheterna för bildskapandet är att fotografen har givits diktatoriska egenskaper om vad och hur något gestaltas, att motivet är endast en liten del av omvärlden som får plats inom bildens restriktiva ram, och kamerans oförmåga att representera en ständigt skiftande natur. Genom olika metoder så som en posthumanistisk vandring, texturering, bildanalys, och en performativ gestaltning skulle den konventionella fotografiska processen utmanas. Senare i designprocessen kom reflekterande objekt fram som en aktör som mycket väl utmanande problemen som ett fotografi annars lider av i sin skapelse. Spegelfragment placerades slumpmässigt framför kameran för att försöka fånga en oavsiktlig del av omgivningen som annars inte hade gestaltats inom bildens restriktiva ram. Designprocessen använde sig även av andra metoder som var mindre lyckade i sitt mål, men som ändå spelade en kritisk del i att leda fram till den slutgiltiga metoden för undersökningens gestaltning. Slutsatsen för arbetet blev att en alternativ process har uppnåtts, men att den gärna hade kunnat utvecklats mer för att bättre använda sig av posthumanismens verktyg. Det mänskliga skulle inte uteslutas ur fotografins skapande, men decentraliseras för att tillåta andra aktörer att ta plats inom fotografins arkiverande värld. / A plunge has been made into the world of posthumanism to investigate its merits to be applied to the process that creates a photography. Several aspects of the posthuman have been identified that would allow for the creation of an alternative photographic process. Some of the major weaknesses of image creation are that the photographer has been granted dictatorial powers over what can be captured by the camera, how the picture only captures a limited view of the world, and the cameras inability to represent an everchanging nature. Through different methods such as a posthuman hike, texturing, image analysis, and a performative design the conventional photographic process were to be challenged. Later in the design stage reflective objects would prove to be a useful actor in challenging the problems that a Kandidatarbete i Medieteknik Oscar Idberg (osid15) Sida 2 av 46 photography faces. Mirror fragments were randomly placed in front of a camera to capture an unintentional part of the surroundings that otherwise would have not fit within the images restrictive frame. The design stage used several other methods that were less successful in their goals, they did however still play a critical role in leading up to the final method for the investigations product. The conclusion acknowledged that an alternative process for the creation of an image had been achieved, it did however not take the investigation far enough and could have better used the posthuman tools available. The human should not be excluded from the photographic process; however, it needs to be decentralized to allow other actors to take their place within the archiving world of photography.

Predição de estenose em acesso vascular para hemodiálise

Moura, Felipe do Carmo January 2017 (has links)
Orientador: Marcone Lima Sobreira / Resumo: A insuficiência renal crônica (IRC) é uma desordem metabólica de instalação lenta e irreversível muito prevalente. Estima-se que existam cerca de 1,2 a 1,5 milhão de pacientes no Brasil. Condições clínicas como: diabetes mellitus, hipertensão arterial sistêmica, lúpus, infecções, traumas são os principais causadores da IRC. Para a realização da hemodiálise são utilizados acessos temporários como os cateteres, ou confeccionada um acesso definitivo que são as fístulas arteriovenosas (FAVs), que podem apresentar complicações como trombose, hipertensão venosa, roubo de fluxo ou infecções, as quais podem contribuir para a perda do acesso. Para análise da condição funcional da FAV, pode-se utilizar o conhecimento da pressão intra-acesso (PIA) venosa e arterial, que podem ser correlacionadas com parâmetros hemodinâmicos como pressão venosa (PV) e o fluxo de sangue (QB) fornecidos durante a hemodiálise pela máquina. Neste estudo prospectivo, serão aferidas as PIAs dos pacientes do setor de hemodiálise do Hospital das Clínicas da Faculdade de Medicina de Botucatu/UNESP que possuem FAV com o objetivo de se identificar sinais indicativos de estenose subclínica, correlacionando-os com os parâmetros ultrassonográficos (velocidade de pico sistólico, velocidade diastólica final e volume de fluxo). O método utilizado baseia-se no isolamento da pressão do sistema e do dialisador visando aferir a pressão estática e coleta dos valores de PV e do QB. Esses dados serão colocados em planilha Excel...

Mesures géodésiques et modélisation de la convergence oblique au travers de failles transformantes. Application au bord Nord du Plateau Tibétain et à la Californie du Sud / Geodetic measurements and modeling of oblique convergence across transform faults. Application to the Northern Tibetan Plateau and to Southern California

Daout, Simon 21 November 2016 (has links)
Je me focalise sur trois grands systèmes de failles transformantes obliques au Tibet et en Californie du Sud, et ce, afin de mieux comprendre et quantifier les relations entre les différentes structures qui les définissent. L'interférométrie radar à Synthèse d'Ouverture (InSAR) dispose du potentiel pour cartographier et localiser précisément la déformation sur des zones étendues et ainsi contraindre la géométrie des structures profondes. Cependant son utilisation en milieu naturel se trouve fortement entravée par la décorrelation due à la végétation, au relief, et aux cycles de gel et dégel, mais aussi par les délais troposphériques et les rampes orbitales résiduelles. J'ai développé des méthodes pour palier ces limitations. Au Tibet, j'ai ainsi traité les archives du satellite Envisat au niveau de deux zones de lacune sismique, à la bordure Nord du plateau, se présentant comme des zones intéressantes pour étudier le partitionnement de la convergence: le système de faille de Haiyuan au north-est Tibet et la faille sénestre de l'Altyn Tagh, au nord-ouest du plateau. Une attention spécifique sur les déformations liées au pergélisol m'a permis de (1) retrouver la continuité du signal sur de grandes zones, (2) de quantifier le comportement temporel des cycles de gel et dégel des sédiments recouvrant le pergélisol, (3) d'isoler les zones stables des sédiments se déformant. Je montre que les déformations saisonnières sont fortement dépendantes des unités géomorphologiques et que la fonte du pergélisol est plus important à faible qu'à haute altitude. J'analyse aussi le signal saisonnier au travers la marche topographique et je définie un proxy pour les incertitudes de la correction atmosphérique. J'observe un gradient de déformation au travers la faille de l'Altyn Tagh de l'ordre de 11-15 mm/an et un alignement claire de la déformation dans le Tarim, parallèle à la faille de l'Altyn Tagh, ainsi que des soulèvements de l'ordre de 1 mm/an associés à des chevauchements. Ce travail montre aussi un gradient de déformation associé à la terminaison ouest de la faille du Kunlun, re-définissant ainsi la géométrie des blocs tectoniques dans cette région. Parallèlement à cette acquisition de données, je développe des outils d'inversion basés sur des algorithmes de Monte Carlo afin d'explorer l'ensemble des géométries en accord avec les observations et d'estimer la compatibilité de la déformation actuelle avec des modèles tectoniques long-termes. Je montre ainsi une convergence uniforme de 8.5-11.5 mm/an et d'orientation N81-98E à travers le système de faille d'Haiyuan et quantifie son partitionnement le long des différentes structures. Par ailleurs, j'applique mon approche en Californie du Sud, au niveau du « Big Bend » de la faille de San Andreas où, en analogie avec des modèles structuraux géologiques, j'utilise des lois de conservations du mouvement pour contraindre la géométrie des chevauchements aveugles. Je montre la compatibilité du champs de déformation actuel avec un décollement grande échelle et quantifie une accumulation de contrainte de 2.5 mm/an le long de la structure majeure sous Los Angeles. / I focus on three major oblique transform faults in Tibet and in Southern California, in order to better measure and quantify the present-day strain accumulation on these structures. Interferometric synthetic Aperture Radar (InSAR) has the potential to map and localize precisely the deformation over wide areas and thus constrain the deep geometry of these structures. However, its application in natural environments in hindered by strong decorrelation of the radar phase due to vegetation, relief, and freeze and thaw cycles, but also due to variable tropospheric phase delays across topographic feature and long-wavelength residual orbital ramps. Here, I develop methodologies to circumvent these limitations and separate tectonic from other parasite signals. In Tibet, I process data from the Envisat satellite archives, at the boundary of the Tibetan plateau, in two seismic gaps, which appear interesting to study the partitioning of the convergence: the Haiyuan Fault system in northeastern Tibet and the left-lateral Altyn Tagh Fault, in northwestern Tibet. A specific focus on the permafrost related deformation signal allows us to: (1) correctly unwrap interferograms from north to south, (2) quantify the temporal behavior of the freeze/thaw cycles, and (3) isolate bedrock pixels that are not affected by the permafrost signal for further tectonic analysis. I show that the seasonal subsidence depends greatly on the geological land unit and that lower elevations are thawing faster than higher elevations. I analyze the atmospheric signal across the high plateau margin and estimate proxy for the uncertainty on atmospheric corrections. I observe a strike-slip deformation of around 11-15 mm/yr across the Altyn Tagh fault, a clear line of concentrated strike-slip deformation of around 3 mm/yr within the Tarim basin, trending parallel to the Altyn Tagh Fault trace, as well as thrust signal uplifting terraces at a rate of 1 mm/yr. This work also shows a strain accumulation around the west extension of the south trace of the Kunlun Fault, redefining the block boundaries in northwestern Tibet. In parallel this data acquisition, I develop Monte Carlo inversion tools in order to explore the various geometries in agreement with observations and estimate the compatibility of actual surface displacements with long-term slip partitioning models. I thus show a uniform convergence rate of 8.5-11.5 mm/yr with a N81-98E across the Haiyuan fault system and quantify the partitioning along the various structures. I also apply my approach in Southern California, across the « Big Bend » of the San Andreas Fault, where, in analogy with structural geological models, I use conservation of motion to help constraining the geometry and the kinematics of blind thrust faults. I show the compatibility of surface displacements with a large-scale décollement and quantify a loading rate of 2.5 mm/yr along the major thrust structure developing under Los Angeles.

The intensity of this type of commercial transactions were identified, based on the index considered for Grubel and Lloyd (1975). Then, its contribution on the total flow of internationally commercialized merchandises was evaluated, based on the methodology proposed for Menon and Dixon (1996). The analysis of the data shows that intra-sectorial commerce have a small contribuition on total commerce results and, despite some primary products and minerals partipate, the main commercialized products from the intra-sectotial commerce are manufactures. In relation to its impacts on the main economic variable, it was verified thar intra-sectotial commerce has positive effects on the generation of new jobs, however its intensification can provoke increases in the concentration of exportation guideline and in the level of income, while reduces the degree of commercial aperture of the State. It was also verified that, statistically, this type of commerce did not show significant effect in the industrialization degree of state of Ceará. / Neste trabalho, procurou-se analisar a participação do comércio intra-setorial nas exportações e os seus impactos sobre as principais variáveis econômicas do Estado do Ceará durante o período de 1996 a 2004. Inicialmente, foi identificada a intensidade desse tipo de transações comerciais com base no índice proposto por Grubel e Lloyd (1975). A seguir, foi analisada a sua contribuição para o fluxo total de mercadorias comercializadas internacionalmente com base na metodologia proposta por Menon e Dixon (1996). Os resultados obtidos mostraram que o comércio intra-setorial tem uma pequena participação no comércio total e que, embora alguns produtos primários e minerais participem desse tipo de comércio, os principais produtos comercializados a partir do comércio intra-setorial são as manufaturas. Em relação aos seus impactos sobre as principais variáveis econômicas, verificou-se que o comércio intra-setorial tem efeitos positivos sobre o emprego, porém sua intensificação pode provocar aumentos no grau de concentração da pauta de exportações e no nível de concentração de renda enquanto reduz o grau de abertura comercial do Estado. Verificou-se, também, que esse tipo de comércio não apresentou efeitos estatisticamente significativos para o grau de industrialização do Ceará.
