I min essä beskriver jag den öppna miljön, med ett modernt och nytänkande arbetssätt som blir allt vanligare inom förskolan. I den nya moderna förskolan öppnas innemiljöerna upp allt mer för att skapa möjligheter till ett ökat samspel och lärande mellan barnen. Pedagogiken säger att vi pedagoger ska bygga miljöer och inspirera barnen till att själva söka kunskap, men här anser jag att det finns barn som får problem. Många barn har svårt att anpassa sig till den stora barngruppen och utmärker sig för att vara "stökiga" eftersom de inte klarar av att sortera alla sinnesintryck runt omkring sig. Jag ser att barn med koncentrationssvårigheter blir allt vanligare inom förskolan och är orsakat av miljön de befinner sig i. Syftet med min essä är att undersöka hur miljön kan vara grunden till barn som har ett oroligt beteende och hur jag som pedagog kan ge dem möjligheter att lättare komma till ro i en verksamhet som saknar avdelade rum. Genom att jag reflekterar över mitt pedagogiska förhållningssätt kommer jag fram till att alla barn inte kan bemötas lika. För att alla barn ska känna en lugn och trygg lärandemiljö på förskolan krävs det att vi pedagoger har kunskap om hur flexibla rum, vardagsstress och stora barngrupper kan påverka barnets koncentration till eget lärande. / In my essay I describe the open environment, with a modern and innovative way of work that is becoming more and more common in preschools. In the new modern preschool the indoor environments are becoming more open to create an increased interaction and learning between the children. The science of education says that the pedagogue shall create environments and inspire the children to search their own knowledge, but according to me this is a something that causes problems for some children. Many children have difficulties to adapt to the large group of children and are characterized as "messy" since they are unable to sort all the perception they are exposed to. I experience that children with concentration disabilities are becoming more and more common at preschools and that it is caused by the environments they are situated in. The purposes of my essay is to investigate how the environment can be the cause of a restless behavior and how I, as a pedagogue, can give them the opportunity to easier find peace in a preschool which doesn’t have any separate rooms. By reflecting over my pedagogical attitude I find that not all children can be met the same way. For every children to experience a calm and safe learning environment at preschool, it is necessary that we pedagogues have knowledge about how flexible rooms, everyday stress and large groups of children can effect the concentration of learning for the child.

Syftet med denna studie är att undersöka hur lärare beskriver erfarenheter av att bemöta tysta elever i skolan utifrån deras kommunikativa och språkliga förmågor. Med hjälp av kvalitativa halvstrukturerade intervjuer med fyra yrkesverksamma lärare på låg- och mellanstadiet presenterar studien hur lärarna beskriver att de bemöter tysta elever i skolan samt hur de beskriver att de anpassar undervisningen för att lyfta fram tysta elevers kommunikativa och språkliga förmågor. Utifrån ett fenomenologiskt perspektiv har intervjuerna tolkats och analyserats med avsikt att lyfta fram lärarnas beskrivningar av sina erfarenheter, bemötanden och anpassningar. En slutsats i denna studie är att lärarna upplever att tysta elevers tysthet är situationsberoende.  Den kan vara beroende av gruppstorleken eller miljön. Ett annat resultat som framkom var att lärarna ansåg att det var betydelsefullt att skapa en trygg undervisningssituation för att få de bästa förutsättningarna för framför allt de tysta eleverna. Lärarna beskrev också olika tillvägagångssätt som de använde för att kunna bedöma elevernas muntliga förmågor. I studien framkom också att lärarna upplevde en del hinder för sina ambitioner att skapa bra undervisningssituationer. Dessa hinder fanns främst på organisationsnivå. / The purpose of this study is to examine how teachers describe the experience of dealing with quiet students at school based on their communicative and linguistic abilities. With the help of qualitative semi-structured interviews with four practicing teachers in primary school the study presents how the teachers describe how they treat quiet students in a school environment and how they describe adapting their own teaching to improve the quiet students´ communication and linguistic abilities. From a phenomenological perspective have the interviews interpreted and analyzed with the intention of highlighting teachers' descriptions of their experiences, responses and adaptations. One conclusion of this study is that teachers feel that quiet students silently depends on the situation. It may depend on the size of the group or the environment. Another finding that emerged was that the teachers felt that it was important to create a safe learning situation to get the best conditions, especially for the silent students. The teachers also described the different approaches they use in order to assess students' oral abilities. The study also revealed that the teachers´ ambitions to create good teaching situations was not obtained without obstacles. These obstacles mainly generated from an organizational perspective.

Syftet med studien är att undersöka körledares uppfattningar om och arbete med icke-verbal kommunikation med kör. I bakgrundskapitlet belyses tidigare forskning och områdesorienterad litteratur som handlar om icke-verbal kommunikation. Datamaterialet består av tre ostrukturerade kvalitativa intervjuer där tre körledare fått reflektera över begreppet icke-verbal kommunikation, hur de uppfattar begreppet och hur de arbetar med icke-verbal kommunikation i körsammanhang. Det teoretiska perspektiv som ligger till grund för studien är det tolkande hermeneutiska perspektivet. I resultatet framkommer att körledare använder sig av olika icke-verbala kommunikationsformer såsom pianot, olika kroppsliga uttryck och rösten. Dessa icke-verbala kommunikationsformer används för att förmedla affekter och undertexter samt för att tolka notbilder. Det framkommer även i resultatet att de tre körledarna har olika syn på dirigering. Vad som är viktigast skiftar från att dirigering är ett otyg till att dirigeringen och tekniken är det viktigaste verktyg en körledare har. Avslutningsvis diskuteras resultatet i förhållande till tidigare forskning och litteratur. / The purpose of this study is to investigate the conductors' perceptions of and work with non-verbal communication with choir performance. The background chapter describes previous research and literature on nonverbal communication. The results of the study came through three unstructured interviews, where three choir conductors reflected over the term non-verbal communication and how they apprehend the concept. The theoretical perspective underlying this study is the interpretative hermeneutic perspective. The results show that conductors use different non-verbal communication methods in their work with choir. The non-verbal communications that the choir leaders, among other things use are the piano, the voice, but they also how reflect over hos sheet music can be interpreted. It is also apparent that the three conductors have different views on conducting. The conductor’s thoughts rang from that conducting is a bad thing and should be used sparingly. Whilst other say that conducting is the most important tool and should not be neglected. In the conclusion, the results are discussed in relation to previous research and literature.

Para sistematizar a produção, majorar a produtividade, suprimir gastos e economizar tempo, empresas aderiram ao telemarketing, principal atividade terceirizada no Brasil e uma das maiores empregadoras do país (665 mil teleoperadores). Todavia, doenças desencadeadas pela atividade laboral são freqüentes em teleoperadores, fato que tem motivado empresas a buscarem recursos no próprio ambiente laboral, como a implementação de uma sala de descanso para seus funcionários, para atender ao recém aprovado Anexo II, da Norma Regulamentadora 17, que instituiu a obrigatoriedade da realização do intervalo para refeição/descanso fora do posto de trabalho. O presente trabalho teve por objetivo verificar, junto a teleoperadores e supervisores de telemarketing, o uso da sala de descanso implementada na empresa e suas opiniões sobre a relação entre uso e afastamentos por motivo de saúde, promovendo uma intersecção entre Psicologia Ambiental e Direito Ambiental do Trabalho. Realizou-se, primeiramente, um estudo piloto com 15 teleoperadores (10 mulheres e 5 homens) e 1 advogado da empresa, resultando em algumas alterações no questionário para teleoperadores. Participaram da pesquisa, fora do ambiente e expediente de trabalho: 80 teleoperadores (48 mulheres e 32 homens), 56% entre 18-25 anos; 73% solteiros; 59% do turno manhã/manhã-tarde; 74% sem ou cursando nível superior, sendo 39% de indicações de ensino médio completo e 35% de ensino superior incompleto; 56% iniciaram na atividade de telemarketing entre 2004-2007 e, nesse mesmo período, 60% ingressaram nessa empresa em que atualmente trabalham; e três supervisores de telemarketing do sexo masculino, entre 26-28 anos, nível superior completo, turno M/M-T, dois solteiros e um casado, contratados entre 2000-2001. Evidenciou-se que: (1) tanto teleoperadores (97%) como supervisores (100%) consideram a atividade parcialmente ou plenamente estressante; (2) durante as curtas pausas, a maioria freqüentemente permanece no refeitório (teleoperadores 71%, supervisores 100%); (3) seja antes (50%), durante (43%) ou após o expediente de trabalho (74%), a maioria nunca utiliza a sala de descanso; (4) relaxamento (41%) e interação (teleoperadores 31%, supervisores 100%) são as atividades mais realizadas pelos teleoperadores, quando do uso da sala; (5) cerca da metade dos teleoperadores (53%) nunca se afastaram, embora 75% dos supervisores indicassem certa freqüência de afastamentos na empresa, porém 60% dos participantes entraram na empresa entre 2004-2007; (6) a maioria atribui fatores positivos à sala (76%) e acredita em sua influência na saúde e bem-estar (teleoperadores 84%, supervisores 75%); (7) 67% dos teleoperadores e 100% dos supervisores julgam necessário ou relevante a implementação de políticas de saúde na empresa, para estimular o uso da sala de descanso e reduzir afastamentos por doenças ocupacionais. Em suma, os resultados evidenciaram o não uso dessa sala de descanso por diversos fatores (ambientais, cultuais, sociais e econômicos), embora os participantes a considerem relevante para a questão da saúde do trabalhador, sugerindo a necessidade de se repensar este espaço, bem como a organização do trabalho, observando-se as sugestões dos participantes apontadas neste estudo, como recreação e interação, atividades que se contrapõem às características rígidas e penosas do telemarketing. (CAPES/CNPq) / To systematize the production, increase productivity, eliminate costs and save time, companies has joined to telemarketing, the main activity outsourced in Brazil and one of the largest employers in the country (665 thousand teleoperators). However, occupational diseases are common in this context, motivating firms to seek resources in this own workplace, such as the implementation of a quiet room for its employees, to mut the newly approved Anexo II, of the Norma Regulamentadora 17 (rule), wich established the obligatory completion of break for meal/rest off workplace. This study aimed to check, next to the teleoperators and supervisors of telemarketing, the use, for teleoperators, of the quiet room implemented in the company and its opinions about relation between use and removal for reason of health, proposing an intersection between Environmental Psychology and Enviromental Labour Law. There was a pilot study with 15 teleoperators (ten women and five men) and a lawyer of the company, resulting in some changes in the final questionnaire for teleoperators. Participated on the survey, out of the company and expediency of work, 80 teleoperators: 48 women and 32 men; 56% between 18-25 years; 73% single; 59% of the turn morning/morning-late; 74% without or taking higher level, with 39% of indications of complete average education and 35% of incomplete higher education; between 2004-2007, 56% had started in the activity of telemarketing and 60% joined the company in wich they work. Three male supervisors had also participated, between 26-28 years, higher level complete, turn morning/late-morning, two singles and one married, recruited between 2000-2001. The results showed no significant differences between the teleoperators (sex/shift of work) and had showed that: (1) 97% of the teleoperators and all the three supervisors had considered the activity partially or fully shessful; (2) during short breaks, 71% of the teleoperators had indicated the frequent use of the cafeteria, also indicated for the three supervisors; (3) the majority of the teleoperators never uses the quiet room, either before (50%), during (43%) or after hours of work expedient (74%); (4) when the use of the room, activities were held more relaxing (indicated by 40% of the teleoperators) and interaction (indicated by 29% of the teleoperators and two supervisors); (5) 54% of the teleoperators has never moved away for health reason, however two supervisors had indicated frequent removals and one, sometimes; (6) 84% of the teleoperators and two supervisors had indicated the influence of the use of the quiet room in health; (7) 67% of the teleoperators and all the supervisors had judged necessary or relevant the implementation of politics of health in the company, to stimulate use of the quiet room and reduce injuries by occupational diseases. In conclusion, although the results showing the non-use by teleoperators of the quiet room, which had the many factors (environmental, personal, cultural, social, economic, etc.), the participants had considered it excellent for the health of the worker, suggesting the need to reflect about this space and the organization of the work, in compliance with the suggestions of participants, such as the need for recreation and interaction, activities no common on the rigid and heavy context of telemarketing.

In this scientific essay I reflect on the relationship that emerges between teacher and student. It is also about the well known superpower that is called adhd and how my own adhd is beeing expressed and manifested throughout my work as a teacher. I reflect on whether my adhd helps or overturns my students and how deep the relationships between teachers and students can be shaped. The main purpose of this essay is to deepen the understanding of the complexity that belongs to the relationship between teacher and student. What I am particularly interested in is the question of what role my adhd has for my opportunities to create good relationships with students with the same diagnosis. The questions I based on are how big of a meaning the experiences have given me with my adhd about the building of relationships but also the relationships with my students? How important are the relationships between a teacher and a student? How deep can a relationship be? Has my ADHD given me an increased understanding of working with students with the same diagnosis? The method I have used is to write an essay, which means that I research and reflect on my own actions and what I may have done differently. By writing this essay, I aim to capture my experiences and reflect on them. This through previous research and literature that deals with my subject. The most important result I came to in my study is that the meaning of the relationship is of great importance in the work with students with ADHD. My own ADHD diagnosis is a big part of creating relationships and deepening them. My ADHD gives me an increased understanding of students with the same diagnosis. Creating the relationship between teacher and student is inevitable and that they become deep and private does not always have to be wrong. A large part of my experience Is that i can connect to my quiet and practical knowledge. / I denna vetenskapliga essä reflekterar jag över relationen som uppstår mellan lärare och elev. Samt den omtalande superkraften adhd och vilken roll min egen adhd tar sig uttryck i arbetet som lärare.  Jag reflekterar över om min adhd hjälper eller stjälper mina elever och hur pass djupa relationer man som lärare får bygga med sina elever. Huvudsyftet med denna essä är att fördjupa förståelsen för den komplexitet som hör till relationen mellan lärare och elev. Det jag i synnerhet intresserar mig för är frågan vilken roll min adhd har för mina möjligheter att skapa goda relationer till elever med samma diagnos. De frågeställningar jag utgått från är hur stor betydelse har de erfarenheter min adhd gett mig i relationsskapandet och i relationerna med mina elever? Hur viktiga är relationerna mellan lärare och elev? Hur djup får en relation bli? Har min adhd gett mig en ökad förståelse i arbetet med elever med samma diagnos? Den metod jag använt mig av är att skriva en essä, det innebär att jag forskar och reflekterar över mitt eget handlande och vad jag kan ha gjort annorlunda. Genom att skriva denna essä har jag som syfte att ta tag i mina erfarenheter och reflektera över dessa. Detta genom tidigare forskning och litteratur som behandlar mitt ämne. Det viktigaste resultatet jag kom fram till i min undersökning är att relationens betydelse är av stor vikt i arbetet med elever med adhd. Min egna adhd diagnos är en stor del till att relationerna skapas och att de blir djupa.  Min adhd ger mig en ökad förståelse för elever med samma diagnos. Att relationen mellan lärare och elev skapas är oundvikligt och att de blir djupa och privata behöver inte alltid vara fel. En stor del av mina erfarenheter kan jag koppla till min tysta och praktiska kunskap.         Nyckelord: Adhd, relationer, förståelse, metoder, praktisk kunskap, tyst kunskap.

Denna studie har som syfte att undersöka hur tystnad gestaltas med hjälp av ljud i filmen A Quiet Place (2018) (John Krasinski, Bryan Woods &amp; Scott Beck med ljuddesign av Erik Aadahl och Ethan Van der Ryn). Studien har även som syfte att undersöka vilka narrativa funktioner ljudet fyller samt bidra till en djupare förståelse för hur det kan används för att skapa en upplevelse av spänning och rädsla.Uppsatsen innehåller en audiovisuell analys av tre scener ur undersökningsmaterialet (A Quiet Place) som består av Michel Chions metod Masking genom vilken en scenbeskrivning och en ljudhändelsebeskrivning upprättats. Dessa två beskrivningar har sedan använts som underlag för en innehållsanalys och Johnny Wingstedt’s narrativa funktionsanalys med författarens tolkning av ljudets berättande funktioner. För att söka svar på hur spänning erhålls med hjälp av ljud har teorier av hjärnforskaren Seth S Horowitz använts i en avslutande och sammanställande analys.Resultatet av analysen visar att tystnad gestaltas genom kontraster, dynamik och att ställa olika ljudnivåer i relation till varandra, en upplevd tystnad är en negation till den ljudnivå som den är ställd i relation till. Ljudet och musikens narrativa funktioner har i stor utsträckning visat sig vara att vägleda åskådarens uppmärksamhet, knyta samman scener och sekvenser i ett linjärt tidsförlopp och understryka känslomässiga uttryck. Studiens resultat tyder även på att upplevelsen av spänning till stor del erhålls på ett liknande sätt som tystnad gestaltas.

<div>The ambient pressure fluctuations within a wind tunnel test environment can severely affect the boundary layer transition witnessed on test articles The Boeing/AFOSR Mach 6 Quiet Tunnel was designed to minimize these fluctuations, also referred to as noise, and is the world's premier facility for studying hypersonic boundary layer transition in a quiet flow environment.

A pitot rake model was designed to allow for an extensive spatial survey of tunnel noise. This model created measurement capabilities that were previously unknown to the BAM6QT facility, including the ability to take concurrent freestream pitot probe measurements.

The flat plate model was streamlined to rectify the startup issue, but no evidence of the second mode instability was found. A 2.5° half angle cone is being designed to replace the flat plate model as a platform for the continuation of this project.</div>

Denna studie är gjord för att belysa och förklara hållbar utveckling utifrån de tre dimensioner som bör tas i beaktning i förskolans verksamhet, de är ekologi, sociala relationer och ekonomi. Detta utifrån förskollärarnas planerade undervisning men också från den tysta kunskap de förmedlar till barnen. I studien används icke-deltagande observationer som datainsamlings metod och datan arbetas därefter genom grundad teori för att nå fram till ett resultat. Det är tydligt att hållbar utveckling är ett begrepp som det arbetas aktivt kring i förskolor idag, men det visar sig uppenbart att den tysta kunskapen som förskollärarna besitter och för vidare till barnen är svår att upptäcka för gemene man och att den därför i allmänhet inte tas i beaktning när man talar om hållbar utveckling inom alla dimensionerna. / This study is designed to elucidate and explain sustainable development based on the three dimensions that should be taken into account in preschool activities, they are ecology, social relations and economics. This is based on the preschool teachers' planned teaching but also from the silent knowledge they convey to the children. In the study, non-participant observations are used as the data collection method and the data is then worked through grounded theory to arrive at a result. It is clear that sustainable development is a concept that is actively worked on in preschools today. But it is evident that the silent knowledge that preschool teachers possess and pass on to the children, is difficult to discover for commoners and that it is therefore generally not taken in when considering sustainable development in all dimensions.

This diploma thesis is covering Québec's policy and Quebec's change of identity from the era of the Quiet revolution. This work covers the changes that were a crucial in the creation of Québec's policy and national identity. From the time of the Quiet revolution in the 60's of the 20th century the society in Québec came through a drastic identity change. And not only in the province itself but also in the whole country of Canada. Because of this change, Québec refused the Canadian policy of multiculturalism. Canadian official policy does not accept Québec as a distinct society and also refuses the principle of the two-nation Canada. Therefore, Québec created its own policy of integration called interculturalism. In the analysis of the development of identity and nationalism, the methodology is a critical examination of the empirical experiences of Québec and the theses of the theoretical concepts of Charles Taylor and Will Kymlicka. It was necessary to study Taylor's and Kymlicka's theses on multiculturalism, identity, communitarianism, and liberalism as a starting point for analyzing the development of Québec. It was important to formulate definitions of identity, nation, and multiculturalism, to determine the main categories of content, and to analyze the development of the Québec identity during...
