Kunskapsbedömning av SO-ämnen i årskurs 1-3 : En studie med utgångspunkt i lärares utsagor om sin bedömningspraktik

Ståtenhag, Natalia January 2018 (has links)
Bedömning är en central och inte helt okomplicerad del i lärarens uppdrag oavsett ämnes- och åldersinriktning. Bedömning av ämneskunskaper i de lägre åldrarna är betingade med åldersrelaterade utmaningar då alla elever i dessa åldrar inte är läs- och skrivkunniga ännu, vilket således kan göra det svårt för läraren att lyckas få ett tillräckligt bedömningsunderlag. Bedömning av SO-ämneskunskaper är omgärdade av en särskild sorts komplexitet eftersom de i läroplanen framskrivna syftena för ämnet inrymmer mer än en tolkning. Det är detta problem som ligger till grund för denna studie vars syfte är att genom lärares egna berättelser få insyn i deras bedömningspraktik i SO-ämnesblocket i årskurs 1–3. Studien utgår från Lee Shulmans teori pedagogical content knowledge (PCK). Datainsamlingsmetoden är dels intervjuer, dels insamling av planeringar och bedömningsexempel.

Výskyt a forma tzv. novinářského subjuntivu (subjuntivo periodístico) v současných španělských žurnalistických textech / The so called journalistic subjunctive (subjuntivo periodístico) in current Spanish journalistic texts

DOUBKOVÁ, Kristýna January 2016 (has links)
The aim of this thesis is to examine the preference in the use of so-called "journalistic subjunctive" in contemporary Spanish journalistic texts. The theoretical part based on specialist literature describes the Spanish modal system. Greater attention is being paid to the subjunctive, its form and use in individual sentences and in subordinate substantive, adjectival and adverbial clauses. The main part of the theoretical part is the introduction of so-called "journalistic subjunctive", therefore imperfect subjunctive form (Pretérito imperfecto de subjuntivo), which is used instead of the indicative past perfect or past tense (Pretérito pluscuamperfecto de indicativo o Pretérito indefinido). This form of subjunctive is a typical feature of journalistic style, so the very end of the theoretical part is dedicated to the characteristics of the Spanish journalistic texts. The research part is an analysis of the occurrence and form of so-called "journalistic subjunctive" on a selected sample of Spanish journalistic texts, focusing on the context of this phenomenon. The basis for the practical part of the thesis is a corpus of Spanish Royal Academy El Corpus del Espa?ol del Siglo XXI (CORPES XXI), which includes texts created from 2001 to 2012.

\"Aplicação de marcadores orgânicos moleculares em estudos oceanográficos e paleoceanográficos: estudo de caso na Margem Continental Superior do Sudeste do Brasil\" / Molecular Organic Markers Application in Oceanographic and Paleoceanographic Studies: Case study at the Southeastern Brazilian Continental Margin

Rafael André Lourenço 29 June 2007 (has links)
Eventos climáticos ocorridos no planeta deixam registros no ambiente, com os quais é possível realizar reconstruções das condições ambientais. No oceano, o destino de grande parte da matéria orgânica é o sedimento; assim o estudo de colunas sedimentares preservadas, testemunhos, fornece um registro de informações sobre os processos biológicos, geológicos e químicos ocorridos no passado e de como esses processos responderam às mudanças ambientais. No presente trabalho foram analisados sedimentos superficiais marinhos ao longo da margem continental superior do Sudeste do Brasil de forma a validar a utilização de marcadores geoquímicos orgânicos na região e foi analisado um testemunho cuja base aponta para 35.000 anos e que engloba importantes eventos climáticos ocorridos no planeta: eventos Heinrich 3, 2 e 1, o Último Máximo Glacial e o evento Younger Dryas, de forma a realizar uma reconstrução paleoceanográfica desse período. Os resultados dos marcadores orgânicos moleculares nas amostras superficiais, quando comparados com outros trabalhos realizados na região, mostraram que os marcadores respondem corretamente aos processos sedimentares na margem continental do Sudeste do Brasil e que a utilização de alquenonas como indicadores de temperatura superficial marinha na região é válida. A análise do testemunho permitiu correlacionar as variações de temperatura da água superficial do mar e variações do nível do mar com o fluxo de material terrígeno para o meio marinho nos últimos 35.000 anos, além de identificar os eventos climáticos citados e verificar a influência desses eventos para a região da margem continental superior do Sudeste do Brasil. Os resultados mostraram uma variação de temperatura superficial marinha de até 4°C entre o Último Máximo Glacial e o Holoceno e mostraram que, para a região, não ocorreu a anti-fase térmica entre o Atlântico Norte e o Atlântico Sul citada em diversos trabalhos realizados no Atlântico Sul, durante os eventos climáticos citados. / Climatic changes produce environmental signatures with which it is possible to reconstruct past environmental conditions. In the ocean, the fate of most of the organic matter is the marine sediment. Sediment core analyses reveal a unique reservoir of biological, chemical and geological information about past processes and how they responded to the environmental changes. In the present work, marine surface sediments from the Southeastern Brazilian Continental Margin were analyzed to verify the efficiency of organic geochemical markers in this area. Sediment core from the Southeastern Brazilian upper slope were also analyzed to carry out a paleoceanographic reconstruction. The core covers a time period of 35,000 years, where important climatic changes occurred, such as the Heinrich events 3, 2 and 1, the LGM, and the Younger Dryas events. Surface sediment results for geochemical markers were comparable with other works developed in the area, efficiently describing the processes that occur there. The alkenone based SST was also comparable with observations from multinational programs, being valid for this area. The core analyses showed correlations between SST and sea level variations with changes in terrestrial organic matter flow to the ocean over the last 35,000 years, allowed the identification of previously mentioned climatic events and the verification of the influence of these events on the Southeastern Brazilian Continental Shelf. Results showed that the SST varied up to 4.5°C between the LGM and the Holocene indicating that at this region a thermal antiphasing between southern and northern Atlantic Ocean SST during the last 35,000 years did not occur.

Seja por uma indistin??o gen?rica que problematiza a categoriza??o de sua obra em uma inst?ncia de g?nero apenas, seja por opera??es que suspendem alguns outros sentidos temporariamente. Dessa forma, este trabalho se prop?e a encontrar esses espa?os de suspens?o, em conson?ncia com o curso ministrado no Coll?ge de France pelo escritor franc?s Roland Barthes em 1977-1978, intitulado O Neutro. Al?m disso, a an?lise comparativa teorizada por Ute Heidmann ajudar? a entender como a suspens?o da configura??o do g?nero textual propicia as zonas neutras que Barthes identificou. A an?lise se prop?e a entender a estrutura??o do texto em uma perspectiva intrincada que leve em considera??o tanto aspectos tem?ticos, quanto discursivos e estruturais. / The work of Caio Fernando Abreu has a very vast and impressive thematic horizon , which is usually the core of the papers on the work of this author . This paper proposes to understand this characteristic of a more intricate point of view : perceive and analyze how the work of the author builds itself thematically , but mainly textually . I n other words , as the text enacts his own writing . From this it is noticeable how the text of Abreu plays with some senses through textual constructions that do not impose directly sense to the reader . Thus, the research sees in the chosen corpus , the collection Os drag?es n?o conhecem o para?so ( 2014 ), the neutral as proposed by the French essayist Roland Barthes (2003 a ). This neutral is understood by Barthes as a possibility to suspend the paradigms that constitute the sense, what exactly justifies the noticeable game in the work of Abreu . This game , to Roland Barthes , is precisely the literature. If the paradigm involves transforming the language , and all language expressions, in a way to propagate ideologies , the literature does not escape this fate . In order to escape this fate , you must fight the language internally ; we must play wit h the language . The neutral is the possibility of the game. Thus , the study sought neutral in Caio Fernando Abreu short stories , presenting it and analyzing it through " figures" which, for Barthes , is a way of perceiving the neut ral through texts , but not in a prescriptive manner. It was proposed , in the analysis , then understand the " Subjectivities ", the " Default ", the " Body " and " Disease " , for example, as possibilities of the game . Finally , in many Abreu?s work instances , the neutral is achieved by textual operations that are not in themselves neutral , but which achieve a " neutral effect ", which explains the game , the literature, in the texts of Caio Fernando Abreu .

Despite the advantages presented using the permeate membranes, such as saving water and reducing water pollution, the concentrate generated in the process ends up being an inconvenience to the deployment of this technology due to lack of sustainable solutions for their management. Thus, the main objective of this research was to evaluate the use of membranes for microfiltration, ultrafiltration, nanofiltration and reverse osmosis concentrated in agriculture, using it as liquid fertilizer. The permeated membranes were also assessed in order to identify activities in which they could be reused. Five configurations were established from four types of membranes, so that each configuration represents a different system. The tests were conducted in batch mode, with triplicate for each configuration. The results indicated that permeated the microfiltration and ultrafiltration can be used in urban areas, in non-potable uses. Have the nanofiltration permeate can be reused in the industry, replacement cooling towers, and other non -potable uses required in the manufacturing unit. The permeate obtained in reverse osmosis met the intended uses for nanofiltration as well as the standards required for boiler feed, adding alkalizing being required to raise the pH to the recommended value. Concentrates generated in nanofiltration and reverse osmosis can be availed as liquid fertilizer in agriculture, but they must be diluted in the irrigation water, in order to adjust the salt concentration allowed for the least tolerant crops patterns / A utiliza??o de membranas filtrantes no p?s-tratamento de esgotos tem sido cada vez mais empregada para obten??o de ?gua com qualidade, aplic?vel a v?rias modalidades de re?so. Apesar das vantagens apresentadas com o uso do permeado de membranas, como a economia de ?gua e a redu??o da polui??o h?drica, o concentrado gerado no processo acaba sendo um inconveniente para a implanta??o dessa tecnologia, devido ? falta de solu??es sustent?veis para seu gerenciamento. Sendo assim, o principal objetivo dessa pesquisa foi avaliar o uso do concentrado de membranas de microfiltra??o, ultrafiltra??o, nanofiltra??o e osmose inversa na agricultura, utilizando-o como adubo l?quido. Os permeados das membranas tamb?m foram avaliados, a fim de identificar em que atividades os mesmos poderiam ser reutilizados. Foram estabelecidas cinco configura??es, a partir dos quatro tipos de membranas, de modo que cada configura??o representou um sistema distinto. Os ensaios foram realizados em batelada, com triplicata para cada configura??o. Os resultados indicaram que os permeados da microfiltra??o e ultrafiltra??o podem ser utilizados no meio urbano, em usos n?o pot?veis. J? o permeado da nanofiltra??o pode ser reutilizado na ind?stria, para reposi??o em torres de resfriamento, e nos demais usos n?o pot?veis requeridos na unidade fabril. O permeado obtido no processo de osmose inversa atendeu aos usos previstos para nanofiltra??o, bem como aos padr?es exigidos para alimenta??o de caldeiras, sendo necess?ria a adi??o de alcalinizante, para elevar o pH at? o valor recomendado. Os concentrados gerados na nanofiltra??o e osmose inversa podem ser aproveitados na agricultura como adubo l?quido, mas precisam ser dilu?dos na ?gua de irriga??o, a fim de adequar a concentra??o de sais aos padr?es permitidos para culturas menos tolerantes

No. of bitstreams: 1 Goncalves_Eliane_D.pdf: 2077207 bytes, checksum: 08c1e86e9f9f60f2f8362ba4564c2271 (MD5) Previous issue date: 2007 / Resumo: Nesta tese exploro como são construídas as noções de ¿mulheres sós¿ no Brasil contemporâneo a partir de três contextos distintos: estudos de população, textos da mídia brasileira e narrativas de mulheres de camadas médias, sem filhos, que moram sozinhas na cidade de Goiânia. Nos estudos de população, mulheres que moram sós são contempladas nas discussões sobre os ¿novos arranjos familiares¿ e na tendência de crescimento progressivo do número de pessoas morando sozinhas (¿domicílios unipessoais¿) observada a partir dos anos 1970. A mídia coloca em ¿evidência¿ o alto número de ¿solitárias¿ nas metrópoles brasileiras e chama a atenção para o estilo de vida das ¿novas solteiras¿, consideradas um fenômeno mundial. O debate ganha relevância nas ciências sociaisbrasileiras e assume uma dimensão de notícia em um processo no qual morar sozinha é freqüentemente associado à idéia de estar ¿solteira¿, compreendida enquanto ausência de vínculos amorosos e sexuais e, conseqüentemente, traduzido como ¿solidão¿. Várias noções atribuídas às mulheres ¿sós¿ nos distintos contextos remetem a algumas idéias proclamadas pelo feminismo, sendo a educação e o trabalho qualificado e remunerado percebidos como centrais à autonomia das mulheres. A partir de algumas terminologias recorrentes nos recortes considerados ¿ ¿nova mulher¿, mulher ¿independente¿, ¿livre¿ e ¿autônoma¿, etc. ¿, proponho uma reflexão sobre as possíveis conexões entre a produção da noção da ¿mulher só¿ e algumas noções centrais do ideário feminista / Abstract: In this thesis, I explore how contemporary notions of ¿single women¿ are constructed in three different contexts: Population studies (Demography), the Brazilian media, and the narratives of middle class childless women living alone in the city of Goiânia. In population studies, women living alone are considered in the discussion of ¿new families¿ and the increasing number of ¿single person households¿ observed beginning in the 1970s. The media emphasizes the ¿evidence¿ of the high proportion of ¿single¿ women in Brazilian metropolitan areas, drawing attention to their ways of life, in what is seen as a worldwide phenomenon. The debate becomes relevant in the Brazilian social sciences and draws the attention of the news in a process in which living alone is often associated with the idea of being single (unmarried), understood as the absence of partnership and sexual life, and therefore translated as ¿loneliness¿. Several notions attributed to single women in the three different contexts resonate with ideas proclaimed by feminism, where education and professional and paid work are perceived as central to the autonomy of women. Regarding recurrent terminologies such as the ¿new woman¿, ¿independent¿ woman, ¿free¿ and ¿autonomous¿, etc, I question the potential connections between the production of the notion of the ¿single woman¿ and key ideas in feminist thinking / Doutorado / Ciencias Sociais / Doutor em Ciências Sociais

De samhällsorienterande ämnena : En studie av de fyra separata ämnenas utrymme och hur de kommer till uttryck i läroböcker för årskurs 1-3

Andersson, Johanna, Borgström, Maria January 2017 (has links)
Läromedelsgranskingen som förr var obligatorisk är nu helt avskaffad och lärare får inta rollen som läromedelsgranskare själva. Tiden som lärare lägger på granskning av läroböcker är dock relativt begränsad. Därför kan läromedelsanalyser av aktuella läroböcker bidra till att lärare får insikt i vad böckerna har att erbjuda. Denna studie syftar till att synliggöra de fyra SO-ämnenas utrymme, hur deras syften kommer till uttryck samt hur djupgående ämnesområden behandlas i SO-läroböcker för årskurs 1-3. För att besvara våra frågor har vi genomfört en jämförande läromedelsanalys av läroböcker i de samhällsorienterande ämnena för lågstadiet. Studien har synliggjort att historieämnet tilldelas störst utrymme i SO- läroböcker och att läroböckerna behandlar innehållsområden med olika mycket djup.Resultatet visar även att geografiämnet får minst utrymme i böckerna och att de sammanfattande punkterna i syftet, ur kursplanen för geografi, behandlas i olika stor utsträckning.

DECONFINED QUANTUM CRITICALITY IN 2D SU(N) MAGNETS WITH ANISOTROPY

D'Emidio, Jonathan 01 January 2017 (has links)
In this thesis I will outline various quantum phase transitions in 2D models of magnets that are amenable to simulation with quantum Monte Carlo techniques. The key player in this work is the theory of deconfined criticality, which generically allows for zero temperature quantum phase transitions between phases that break distinct global symmetries. I will describe models with different symmetries including SU(N), SO(N), and "easy-plane" SU(N) and I will demonstrate how the presence or absence of continuous transitions in these models fits together with the theory of deconfined criticality.
