Den goda barndomen och det goda föräldraskapet : En kvalitativ studie om framställandet av barnets bästa i LVU-domar. / The good childhood and good parenting

Rydh, Rebecca, Granström, Julia January 2023 (has links)
Syftet med denna kvalitativa dokumentstudie har varit att studera hur barnets bästa framställs i förvaltningsrättens domar av upphörande av vård enligt lagen med särskilda bestämmelser om vård av unga, samt att analysera hur socialnämnd, förvaltningsrätt, föräldrar och barnet själv argumenterar för barnets bästa. Studien syftar även till att undersöka hur föräldraförmåga sätts i relation till barnets bästa. I vår studie har 43 domar granskats med hjälp av tematisk analys. Studiens teoretiska utgångspunkt har varit barndomssociologi samt Bronfenbrenners utvecklingsekologiska teori. Resultatet visar att barnets bästa inte framställs begreppsligt, utan i relation till den goda barndomen och det goda föräldraskapet. Den goda barndomen innefattar i det här sammanhanget att barn ska växa upp under trygga förhållanden som präglas av stabilitet, kontinuitet och känslomässig omsorg. Det goda föräldraskapet kännetecknas av insikt, samarbete och mottaglighet för förändring. Ett gott föräldraskap kännetecknas också av föräldrar som har förmågan att tillgodose barnets behov och kan sätta barnets behov i första hand. Föräldrar i domarna konstrueras av socialnämnd och förvaltningsrätt som föräldrar som saknar föräldraförmåga, och därmed inte har förmåga att tillgodose barnets bästa. Föräldrar argumenterar ifrån att föräldrarna själva erhåller ett gott föräldraskap. Både barn och föräldrar påtalar återföreningsprincipen och framför vikten av att barnet bor med sin biologiska familj. Barnets uppfattning av vad som är bäst för barnet kopplas till känslor av trygghet till barnets omsorgspersoner.

Content Analysis of New Teacher Induction and Mentoring Documents in Five Partnership Districts: Reflections and Acknowledgments of Complexity

Larsen, Carol S. 20 March 2013 (has links) (PDF)
The purpose of this study is to examine how documents used in new teacher induction and mentoring programs from five different school districts reflect and acknowledge the complexity of the programs of which they are a part. Extensive research has been conducted regarding various aspects of these two programs, often utilizing linear approaches to these programs. Research has called for analysis of the complexity of these programs. New teacher induction and mentoring documents were collected from each of the five districts, resulting in approximately 76 documents total. Documents were categorized into three main groups: mentor documents, mentee documents, and district documents. Each document was read and analyzed through two phases of data analysis. Phase I of analysis reports on the language contained in the documents related to seven emergent categories. Phase II of analysis connects the language of the documents of the seven emergent categories to the eight indicators of complexity as outlined by Davie and Sumara (2006). Two appendices contain the details of analysis, one appendix for each phase. Findings suggest that most documents contained elements reflecting and acknowledging the complexity of the two programs as well as elements of linear thinking. Lack of reflection of complexity is addressed. Suggestions for further research are given.

Dokument- och diskursanalys av läroplaner i grundskolans musikämne : Med fokus på skolans mål och riktlinjer samt olika kunskapsformer / Document and discourse analysis of curricula in the compulsory school and the subject of music : Focusing on the goals and guidelines of the school as well as various forms of knowledge

Hellman, Per January 2022 (has links)
Music educational and curriculum research underlies the genesis of the study. Document analysis and discourse analysis have been applied as a theoretical framework as well as a method for describing and analyzing projections between the school's mission, goals and guidelines and how it is textually told about knowledge in comparison with Aristotle's forms of knowledge. The study is based on compulsory school curricula and subject plans in music from the years 1962, 1980 and 2011. The result shows that the differences are in the school's abandonment goals are minimal concerning ideology that rests on a democratic foundation. On the other hand, different qualities or characteristics are promoted, where, among other things, Lgr 62 emphasizes man's theoretical or intellectual abilities in contrast to Lgr 80, which emphasizes responsibility-taking and creation of a more practical nature. Lgr 11, on the other hand, lifted mixed qualities from previous curricula, but nevertheless claims that language is man's greatest tool. Differences concerning practical versus theoretical knowledge in the subject plans' purpose and goals as well as main points and central content are illustrated. In the objective description of the 1962 syllabus, practical experience is emphasized, while the 1980 syllabus focuses on theoretical knowledge such as discussing music. Lgr 11 emphasizes both practical and theoretical knowledge in the purpose description. Based on the main points and central content of the subject plans, the result shows that the knowledge that has been made visible falls within the categories of singing, playing and listening, and through this categorization Aristoteles forms of knowledge could then be applied. Clear connections to purpose and goals with the form of knowledge episteme could be found in the 1980 curriculum and Techne through the 1962 curriculum. Phronesis was made visible in 1962 and through the 2011 subject plan. Touching writings in main moments and central content, the result showed that episteme could relate to knowledge in "singing", techne in "playing" and phronesis in "listening".

Mapeamento de dados multidimensionais usando árvores filogenéticas: foco em mapeamento de textos / Mapping multidimensional data using phylogenetic tress: focus text mapping

Valdivia, Ana Maria Cuadros 01 October 2007 (has links)
A Visualização Computacional trata de técnicas para representar e interagir graficamente com dados complexos, em geral de alta dimensionalidade. Dados de alta dimensionalidade são caracterizados por pontos representados em espaços vetoriais de alta dimensão, cada coordenada representando um atributo do vetor. Num grande número de aplicações da visualização multidimensional uma medida de similaridade existe entre esses vetores. Técnicas de projeção multidimensional podem ser utilizadas para posicionamento desses dados num plano de forma a facilitar a interpretação das relações de similaridade. Entretanto alguns problemas dessas técnicas comprometem a interpretação dos resultados obtidos. Este trabalho identifica esses problemas e propõe, uma técnica para posicionar os pontos no plano, através da formação de árvores filogenéticas a partir de relações de similaridade. Em geral árvores filogenéticas são utilizadas para codificação de relações de ancestralidade. Um algoritmo de geração e um algoritmo de traçado dessas árvores foram implementados no contexto do sistema PEx (Projection Explorer) e a solução é comparada com a funcionalidade das projeções na interpretação de dados multidimensionais em geral e, em particular, na representação de coleções de documentos, uma aplicação bastante estratégica da visualização computacional e da mineração visual de dados / Computational Visualization is concerned with graphical representation and exploration of complex data, usually bearing high dimensionality. Multidimensional data are characterized by points represented in vector spaces of many dimensions, each coordinate representing an attribute of the vector. In many applications a similarity measure can be found to highlight relationships of proximity between the vectors. In this environment projection techniques offer an alternative to ease interpretation coded by the similarity measures through proximity on the display. They do so by positioning the points on a bidimensional plane. Projection techniques are very useful to display and interact with data, but present some drawbacks that in some cases compromise the interpretation of certain features in data sets. This work discusses such problems and proposes, as an alternative to represent similarity relationships and to provide point placement on a plane, the use of phylogenetic trees, a representation typically employed to represent ancestrality relationships. An algorithm for generation and an algorithm for drawing such trees were implemented in a system called Projection Explorer. The approach is compared to that of multidimensional projections for multidimensional data in general and, in particular, for document data sets, an strategic application for multidimensional visualizations, since text can be represented and interpreted as multi-dimensional entities

End-to-End Full-Page Handwriting Recognition

Wigington, Curtis Michael 01 May 2018 (has links)
Despite decades of research, offline handwriting recognition (HWR) of historical documents remains a challenging problem, which if solved could greatly improve the searchability of online cultural heritage archives. Historical documents are plagued with noise, degradation, ink bleed-through, overlapping strokes, variation in slope and slant of the writing, and inconsistent layouts. Often the documents in a collection have been written by thousands of authors, all of whom have significantly different writing styles. In order to better capture the variations in writing styles we introduce a novel data augmentation technique. This methods achieves state-of-the-art results on modern datasets written in English and French and a historical dataset written in German.HWR models are often limited by the accuracy of the preceding steps of text detection and segmentation.Motivated by this, we present a deep learning model that jointly learns text detection, segmentation, and recognition using mostly images without detection or segmentation annotations.Our Start, Follow, Read (SFR) model is composed of a Region Proposal Network to find the start position of handwriting lines, a novel line follower network that incrementally follows and preprocesses lines of (perhaps curved) handwriting into dewarped images, and a CNN-LSTM network to read the characters. SFR exceeds the performance of the winner of the ICDAR2017 handwriting recognition competition, even when not using the provided competition region annotations.

Analysis and Visualisation of Edge Entanglement in Multiplex Networks

Renoust, Benjamin 18 December 2013 (has links) (PDF)
When it comes to comprehension of complex phenomena, humans need to understand what interactions lie within them.These interactions are often captured with complex networks. However, the interaction pluralism is often shallowed by traditional network models. We propose a new way to look at these phenomena through the lens of multiplex networks, in which catalysts are drivers of the interaction through substrates. To study the entanglement of a multiplex network is to study how edges intertwine, in other words, how catalysts interact. Our entanglement analysis results in a full set of new objects which completes traditional network approaches: the entanglement homogeneity and intensity of the multiplex network, and the catalyst interaction network, with for each catalyst, an entanglement index. These objects are very suitable for embedment in a visual analytics framework, to enable comprehension of a complex structure. We thus propose of visual setting with coordinated multiple views. We take advantage of mental mapping and visual linking to present simultaneous information of a multiplex network at three different levels of abstraction. We complete brushing and linking with a leapfrog interaction that mimics the back-and-forth process involved in users' comprehension. The method is validated and enriched through multiple applications including assessing group cohesion in document collections, and identification of particular associations in social networks.

No. of bitstreams: 1 nunes_ps_dr_bauru.pdf: 3291691 bytes, checksum: fd718fcfe90cb9a708df028a9adcf54c (MD5) Previous issue date: 2016-06-03 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Frederic Edward Clements (1874-1945) foi um botânico e ecólogo estadunidense. Realizou trabalhos principalmente na área de Ecologia Dinâmica. Recebeu reconhecimento perante a comunidade científica, sobretudo após a publicação do livro "Plant Succession: an analysis of the development of vegetation", em 1916. Nessa obra defendeu a metáfora das formações vegetais como entidades orgânicas, o superorganismo. Após esse trabalho foi convidado a integrar o corpo de pesquisadores da Instituição Carnegie, em Washington (EUA), conseguindo assim maiores financiamentos para as suas pesquisas. Seus trabalhos, alvos de críticas e elogios, contribuíram para a institucionalização da Ecologia enquanto ciência no século XX. Tendo em vista a importância das ideias desse autor para a estruturação desse campo, objetivou-se neste trabalho investigar as suas contribuições, a partir de fontes originais, com o propósito de oferecer subsídios para a discussão a respeito de seus aportes para o ensino da Ecologia no nível superior de educação. A fim de que compreendêssemos mais profundamente o alcance de sua obra, foram realizadas entrevistas com seis professores universitários, que além de discutirem a obra de Clements, ainda teceram diálogos sobre a inclusão da História e Filosofia da Ciência no ensino. Esse fato é interessante, pois a história da ciência, segundo pesquisadores da área, pode configurar-se como uma ferramenta importante para a aprendizagem científica. Cabe ressaltar que as entrevistas foram analisadas pelo método da análise de conteúdo e as obras, por meio de análises documentais. Após a triangulação dos dados foi verificado que Clements trouxe importantes contribuições para a Ecologia, como a elaboração de novos conceitos, inserção de terminologias, criação de métodos de pesquisa – como o método de parcelas, confecção de instrumentos para trabalhos de campo, discussão sobre critérios de rigor científico para a área e, ainda, trouxe uma visão sistêmica para os ambientes naturais. Para o ensino, especificamente, contribuiu com a elaboração de experimentos e procedimentos para aulas de campo destinadas a alunos universitários. Ainda hoje seus trabalhos estão presentes em livros-texto utilizados nos cursos de graduação de Biologia e Ecologia, confirmando assim o reconhecimento da sua importante contribuição como pesquisador. / Frederic Clements (1874-1945) was an American botanist and ecologist who carried out works mainly in Dynamic Ecology field. He received recognition from the scientific community, especially after the publication of "Plant Succession: an analysis of the development of vegetation", in 1916. In this work, he defended the analogy of plant formations as organic entities, the superorganism. After this work, he was invited to join the body of researchers on the Carnegie Institution, in Washington, DC (USA), thereby achieving greater funding for his research. His works, targets of criticism and praise, contributed to the strengthening of Ecology as a science in the twentieth century. Given the importance of this author's ideas to the structuring of this field, the aim of the present work was to investigate his contributions, based on the original sources, in order to provide subsidies for discussion of his additions to the teaching of Ecology in higher education. To broadly understand the scope of his work, interviews were conducted with six university professors. Besides discussing Clements' production, they dialogued on the inclusion of History and Philosophy of Science in education. This is an interesting fact because, according to researchers in the field, the History of Science can be configured as an important tool for scientific learning. It is worth noting that the interviews were analyzed by content analysis method, and the works by documental analysis. After analysis, it was confirmed that Clements brought many contributions to Ecology, as the development of new concepts, introduction of terminologies, creation of research methods – as the quadrat method, creation of fieldwork instruments, discussion on scientific rigor criteria on this area, and even brought a systemic vision of the natural environment. Specifically on teaching, he contributed through the preparation of experiments and procedures for field classes for college students. Even today, his works are present in textbooks used in Biology and Ecology undergraduate courses, conforming the recognition of his remarkable contribution as a researcher.

Att hantera tillvaron i den psykiatriska tvångsvården : En dokumentanalys av patienters bloggtexter / To handle the context within the psychiatric compulsory care : A document analysis of blogs

Berg, Lalita, Nilsson, Emma January 2018 (has links)
Psychiatric compulsory care is a complex field. It could be argued that the first and foremost difficulty lies in challenging the autonomy of the patients. The care includes control and restrictions, while simultaneously seeking cooperation and improvement from the patient; creating a very difficult surrounding. Therefore, the aim of this study was to understand how inpatients handled the complex context within the psychiatric compulsory care. Our study was a document analysis, where we analyzed blogs written by current and former inpatients. We analyzed the data using Lazarus theory about how people cope with internal and external stress in difficult situations. Within the theory, a number of different strategies as to how people cope with these situations are described. We identified three main strategies to manage the compulsory care; acceptance, avoidance and making time pass. We also identified unique ways of managing the care; using humor, writing on the blog and viewing the care as separated from their “normal world”. To sum up the main conclusions, we found that coping seemed to be a constantly changing process including different strategies, both emotional and behavioral. Lastly, our study showed that the context a person is in matters; the patients handled the situation with the possibilities within the compulsory care, and also seemed to create their own ways to cope.

Segmentation and indexation of complex objects in comic book images / Segmentation et indexation d'objets complexes dans les images de bandes dessinées

Rigaud, Christophe 11 December 2014 (has links)
Dans ce manuscrit de thèse, nous détaillons et illustrons les différents défis scientifiques liés à l'analyse automatique d'images de bandes dessinées, de manière à donner au lecteur tous les éléments concernant les dernières avancées scientifiques en la matière ainsi que les verrous scientifiques actuels. Nous proposons trois approches pour l'analyse d'image de bandes dessinées. La première approche est dite "séquentielle'' car le contenu de l'image est décrit progressivement et de manière intuitive. Dans cette approche, les extractions se succèdent, en commençant par les plus simples comme les cases, le texte et les bulles qui servent ensuite à guider l'extraction d'éléments plus complexes tels que la queue des bulles et les personnages au sein des cases. La seconde approche propose des extractions indépendantes les unes des autres de manière à éviter la propagation d'erreur due aux traitements successifs. D'autres éléments tels que la classification du type de bulle et la reconnaissance de texte y sont aussi abordés. La troisième approche introduit un système fondé sur une base de connaissance a priori du contenu des images de bandes dessinées. Ce système permet de construire une description sémantique de l'image, dirigée par les modèles de connaissances. Il combine les avantages des deux approches précédentes et permet une description sémantique de haut niveau pouvant inclure des informations telles que l'ordre de lecture, la sémantique des bulles, les relations entre les bulles et leurs locuteurs ainsi que les interactions entre les personnages. / In this thesis, we review, highlight and illustrate the challenges related to comic book image analysis in order to give to the reader a good overview about the last research progress in this field and the current issues. We propose three different approaches for comic book image analysis that are composed by several processing. The first approach is called "sequential'' because the image content is described in an intuitive way, from simple to complex elements using previously extracted elements to guide further processing. Simple elements such as panel text and balloon are extracted first, followed by the balloon tail and then the comic character position in the panel. The second approach addresses independent information extraction to recover the main drawback of the first approach : error propagation. This second method is called “independent” because it is composed by several specific extractors for each elements of the image without any dependence between them. Extra processing such as balloon type classification and text recognition are also covered. The third approach introduces a knowledge-driven and scalable system of comics image understanding. This system called “expert system” is composed by an inference engine and two models, one for comics domain and another one for image processing, stored in an ontology. This expert system combines the benefits of the two first approaches and enables high level semantic description such as the reading order of panels and text, the relations between the speech balloons and their speakers and the comic character identification.
