Föräldrars frågor till barn : En analys av dialoger med 2-åringar med olika utvecklat ordförrådEdlund, Karin January 2016 (has links)
Det huvudsakliga syftet med denna uppsats är att undersöka hur föräldrar ställer frågor till barn i en ålder av 2;3- 2;5 år med olika utvecklat ordförråd. Ett annat syfte med uppsatsen är att undersöka om barnen ger respons på föräldrarnas frågor samt om barnen själva ställer frågor. De frågeställningar som står i fokus är: Hur många ord och yttranden säger barn och föräldrar? Vilka typer av frågor ställer föräldrarna? Ställer barnen frågor och i så fall i vilken omfattning? Ger barnen respons på föräldrarnas frågor och i så fall i vilken omfattning? Är frågor överlag effektivt för att få barn i åldersgruppen att tala? Frågeställningarna besvaras genom språkanalyser av transkriberade dialoger mellan föräldrar och barn. Transkriptionerna omfattar tre timmar dialoger totalt och materialet har analyserats med hjälp av CLAN. Deltagarna är nio familjer från SPRINT-projektet vid Stockholms universitet. Deltagarna är utvalda för att representera barn med låg- respektive hög ordförrådsnivå baserat på SECDI data, ett svenskt normerat instrument i syfte att mäta barns ordförråd. Resultatet visar totalt cirka 2 500 yttranden från föräldrarna och drygt 900 från barnen. I ord räknat omfattar materialet totalt cirka 11 000 ord från föräldrarna och drygt 2 000 ord från barnen. Det råder stora procentuella skillnader mellan den högpresterande gruppen (höggruppen) och den lågpresterande gruppen (låggruppen) vad angår barnens antal yttranden och ordförråd till fördel för höggruppens barn. Föräldrarna visar inte på lika tydliga skillnader som barnen, men föräldrarna till barnen i höggruppen gör fler yttranden och använder ett mer varierat ordförråd än i låggruppen. Frågor är vanligt förekommande i föräldrars kommunikation med barn. Det framkommer att totalt för båda grupperna utgör frågor cirka en tredjedel av föräldrarnas yttranden. Vanligt förekommande frågor är ja/nej- frågor, produktiva frågor och frågor med hjälpverb. Barnen i höggruppen ger oftare respons på föräldrarnas frågor än barnen i låggruppen. Likaså ställer barnen i höggruppen oftare egna frågor än barnen i låggruppen. Den tydliga diskrepansen mellan grupperna indikerar att det finns samband mellan kvantitetsfaktorer i föräldrarnas och barnens tal samt att frågor är en metod som kan generera tal från barnen. Det kan finnas anledning att fundera över frågors olika komplexitet i förhållande till barnets ålder och övriga utveckling eftersom det framkommer att föräldrar generellt ställer komplicerade frågor. / The primary purpose of this paper is to explore how parents ask questions to toddlers (in this paper 2;3-2;5 year old children) with different vocabulary development. Another purpose of this paper is to explore if the children respond to questions given by their parents, and if the children ask questions themselves. Questions in focus for this paper are: How many words and utterances are said by the children and the parents? What kind of questions do the parents ask? Do the children ask questions, and if so, to what extent? Do the children respond to the parents’ questions, and if so, to what extent? Are questions generally effective in getting children to talk? The questions are answered through language analysis by transcribed dialogues between parents and children, where the transcriptions cover three hours of dialogues in total. The material has been analyzed in CLAN. The participants are nine families from the SPRINT-project at Stockholm University. The participants are selected to represent children with low- or high vocabulary based on SECDI data, a Swedish standardized instrument for measuring children’s vocabulary. The result shows about 2 500 utterances by the parents, and more than 900 by the children, while the number of words is approximately 11 000 words by the parents and more than 2 000 by the children. Concerning the children’s utterances and vocabulary there are large differences in percentage between the groups, with an advantage for the children in the high performing group (HP group). The parents don’t show such distinct differences, but the parents in the HP group make more utterances and use more variation in their vocabulary than the parents in the low performing group (LP group). Questions are frequently used in parents’ communication with children. In total, for both groups, questions constitute one third of the parents’ utterances. Commonly occurring are yes- no questions, productive questions and questions with auxiliary verbs. The children in the HP group more frequently respond to their parents’ questions than the children in the LP group. Similarly, children in the HP group more frequently ask questions than the children in the LP group. The distinct discrepancy between the two groups indicates causality between quantity factors in parents’ and children’s speech. It also indicates that the use of questions may in general be an effective method for triggering children’s speech. In general parents ask complicated questions, and therefore it may be appropriate to consider variations in question complexity in relation to the child’s age and overall development.

Previous issue date: 2013-02-05 / This paper presents empirical evidences for the credit channel in Brazil based on Holtemöller’s (2002) previous work. For that matter, it was made a descriptive analysis on Brazilian credit evolution and econometric tests using monetary, credit and real economy data. It is possible to observe rising credit importance in the last years, as well as improving corporate financing through issuances in asset markets. Therefore, one could expect greater significance of bank lending channel in the monetary policy transmission mechanism. However, empirical analysis indicates that its effects on economic activity are restricted. After estimating the interest rate channel using vector autoregressive models, we have included credit variables to evaluate its impacts on output. Despite concluding that monetary policy shocks do have effects on loan supply, the impacts of restrictive credit conditions on industrial production is limited. Some specific characteristics of Brazilian economy are presented in the attempt to try to justify this result. / Este trabalho traz avaliação empírica a respeito do canal de crédito no Brasil, feita com base no artigo de Holtemöller (2002). Para tanto, foi feita análise descritiva sobre a evolução do crédito no país, bem como testes econométricos utilizando dados monetários, de crédito e economia real. Observamos o aumento da importância do crédito nos últimos anos, assim como o aumento do endividamento corporativo via emissão de títulos. Portanto, seria natural esperar que o canal de crédito no mecanismo de transmissão da política monetária também se tornasse mais importante. Contudo, a análise empírica mostra que seus efeitos sobre a atividade econômica são limitados. Após estimações feitas para o canal monetário tradicional, a partir de vetores autorregressivos estruturais (SVAR) com vetores de correção de erros (VEC), incluímos variáveis de crédito para avaliar o impacto sobre o produto. Apesar de concluirmos que choques de política monetária possuem efeitos sobre a oferta de crédito, o impacto de condições creditícias restritivas sobre a produção industrial é pequeno. Alguns fatores como a existência de crédito corporativo direcionado via BNDES, maior importância da captação via mercado de capitais, medidas macroprudenciais adotadas e aumento do prazo médio concorrem para esse resultado.

Artificiell intelligens inom mammografiscreening : En litteraturstudie / Artificial intelligence in mammography screeningCarrass-Milling, Anders, Johansson, Camilla January 2020 (has links)
Den senaste utvecklingen av artificiell intelligens (AI) och djupinlärning (DL) har gjort bild- och funktionsmedicin till en högst trolig kandidat att tidigt anta tekniken. AI inom mammografiscreening syftar till hälsofrämjande effekter genom en förhoppning om säkrare bilddiagnostik. Röntgensjuksköterskans (RSS) arbete präglas av korrekt utförd bildtagning och ett aktivt aktualiserande av den egna yrkesrollen gällande såväl tekniska framsteg som förnyade arbetssätt. Litteraturstudien har upprättats i syfte att belysa potentiella effekter av AI på bilddiagnostik inom mammografiscreening. Genom manifest innehållsanalys av resultat erhållna ur ämnesrelevanta vetenskapliga studier publicerade i databaserna Cinahl och Medline under år 2019–2020 identifierades och beskrevs kategorier sammanställda av subkategorier med liknande innehåll. Effekter inom granskningsprocessen och diagnostisk säkerhet skildrar flera perspektiv gällande AI:s effekter på bilddiagnostik. Utöver en stundtals ökad förmåga till cancerdetektion vid AI-assistans har artificiell bildgranskning även visat sig kunna reducera arbetsbördan för radiologer i form av friskrivning av mammogram med låg sannolikhet för bröstcancer. Vid tillämpning av AI ses lovande effekter inom framförallt klassificering av bröstvävnad samt vid reducering av falska positiva svar. Forskningen förbehålls dock med kvarstående etiska dilemman och avsaknad av ett juridiskt ramverk, vilket lämnar utrymme för vidare studier. / Recent developments in artificial intelligence (AI) and deep learning (DL) have made diagnostic imaging a prime candidate to adopt the technology. AI in mammography screening aims at promoting health with hopes of higher diagnostic accuracy. The radiographers work is characterized by properly performed imaging and actively updating the profession regarding technical developments and renewed working methods. The aim of this systematic review was to illustrate feasible effects of AI on diagnostic imaging within mammography screening. Through manifest content analysis of results obtained from subject related scientific studies published 2019–2020 in the databases Cinahl and Medline the authors identified and described categories compiled by subcategories with similar contents. Effects within the image interpretation process and diagnostic accuracy describes several perspectives regarding the outputs of AI on diagnostic imaging. AI-systems have proven to be useful in both assisting with image interpretation and reducing the workload for radiologists by disclaiming mammograms with low probability of breast cancer. Most promising effects are seen in the classification of breast tissue and reduction of false positives, but research is challenged by ethical dilemmas and the need for a legal framework, which are areas suggested for future research.

Hodnocení lomového chování svarových spojů používaných v energetickém průmyslu / An assessment of fracture behaviour of weld joints used in the power industryRádsetoulal, Milan January 2021 (has links)
This thesis is focused on assessment of fracture behaviour of heterogeneous welded joint. The goal is to determine fracture behaviour at the interface of ferritic base metal and austenitic weld metal at temperature of 255°C. This kind of weld is widely used at energy industry. Fracture toughness was evaluated using CT specimens with size 0,5T in order to determine the initiation values of stable crack propagation. Fracture behaviour of the weld is correlated with results of metallography and fractography analysis. Both light and scanning electron microscopy is used for fractography analysis. An assessment of fracture behaviour of the interface of the weld joint is first of all connected with a need of suitable location of cycled crack to the interface of metals. In the case of well-prepared crack the lowest values of J-integral are observed. In other cases of slight crack deviation from the notch plane fracture values increase. Due to a large scatter of mechanical properties of heterogeneous weld joints an increased number of test specimens is needed to obtain relevant and conservative fracture toughness values. Correlation of fracture toughness with the results of fractography analysis leads to clarification of the crack trajectory and to description of fracture mechanism.
