Denna uppsats syftar till att undersöka hur influencern Bianca Ingrosso framställer klädkonsumtion på YouTube. Med en bakgrund av en ökad medvetenhet kring klädkonsumtionens klimatpåverkan genomfördes en kritisk diskursanalys för att undersöka hur Bianca Ingrosso idag kan ha makt över konsumtionsdiskursen och därmed upprätthålla ohållbara konsumtionsnormer i samhället. Syftet var således att skapa en kritisk språkmedvetenhet över hur språk kan upprätthålla maktrelationer i samhället. Studien har sin utgångspunkt i Baumans teori om konsumtionssamhället, Rosas teori om social acceleration och Scheffs teori om sociala band. Resultatet visade att Bianca Ingrosso framställer klädkonsumtion på ett sätt som kan vara avgörande för individens mående, sociala relationer, identitetsbildande och sociala position i samhället. Resultatet av studien kopplades sedan in i en större samhällelig kontext vilket visade att Ingrosso upprätthåller och reproducerar en konsumtionskultur som kan vara svår att förändra. Orsaken till detta kan vara att den är djupt förankrad i både samhällets sociala, kulturella och ekonomiska strukturer. / This study aims to investigate how the influencer Bianca Ingrosso portrays clothing consumption on YouTube. With a background of increased awareness of the climate impact of clothing consumption, a critical discourse analysis was carried out to investigate how Bianca Ingrosso have power over the consumption discourse and thereby maintain unsustainable consumption norms in society. The aim was thus to create a critical language awareness of how language can maintain power relations in society. The study has its starting point in Baumans theory of consumer society, Rosas theory of social acceleration and Scheffs theory of social bonds. The result showed that Bianca Ingrosso portrays clothing consumption in a way that can be decisive for the individual's well-being, social relationships, identity and social position in society. The results of thes tudy are then linked into a larger societal context, which showed that Ingrosso maintains and reproduces a consumption culture that can be difficult to change given that it is deeply rooted in both society's social, cultural and economic structures.

The demands on becoming more and more effective and within a short period of time is weights heavy on the workers in the workplace. The purpose of this study is to examine how workers with stressful, white-collar professions experience heavy workloads and high demand on availability and efficiency and how they experience risk factors in the workplace affect their mental health from the symptoms of exhaustion. To answer the study´s purpose three questions were created. Seven qualitative interviews were conducted all with participants of different white-collar professions and between the age of 25-65. In addition to the study´s main theory of modern acceleration (Rosa, 2014) Foucault's (2017) theory of good dressage and the concept of internalization from Berger and Luckmann (1991) to analyze the material together with previous research on engagement was the basis for parts of the analysis. The Result was that all participants had their mental health affected negatively by work related stress because of the modern accelerations. All participants had experience work related stress in combinations with feelings of shame and feeling of depression and exhaustion occurred in some participants. / Kraven på att effektivisera blir allt större, inte minst på arbetsplatsen där arbetstagarna ofta har många arbetsuppgifter och lite tid att hinna utföra de på. Syftet med studien är att undersöka stressade tjänstemän som upplever höga prestationskrav och hur de som en följd av modernitetens acceleration upplever att riskfaktorerna på arbetsplatsen påverkar deras psykiska mående utifrån utmattningssymtomen. För att besvara studiens syfte identifierades tre frågeställningar. Sju kvalitativa intervjuer utfördes på informanter som alla arbetade inom olika tjänstemannayrken och var mellan 25–65 år gamla. Utöver studiens huvudsakliga teori om modernitetens acceleration (Rosa, 2014) användes även Foucaults (2017) teorin om den goda dressyren och begreppet internalisering från Berger och Luckmann (1991) för att analysera materialet samt tidigare forskning om engagemang la till grund för delar av analysen. Resultatet var att alla informanter hade en negativt påverkad psykisk hälsa som berodde på arbetsrelaterad stress som en konsekvens av modernitetens acceleration. Samtliga informanter upplevde arbetsrelaterad stress som var kombinerad med känslor av skam men känslor av depression och utmattning förkom hos vissa.

The purpose of this study is to extend the knowledge regarding teachers in the primary school's early years' perception of students with special talents. Furthermore, how they describe and reflect about their mathematical teaching for these gifted students. To extend the knowledge about this topic and in regards to answering the two research questions, the study takes a qualitative approach in addition to using a sociocultural perspective of the proximal development zone, support, language, interaction, creativity and prodigies as a theoretical framework. The result of the study shows that teachers perceive different characteristics as representative characteristic of gifted students, as high memory capacity and developed mathematical thinking. Furthermore, teachers have a positive attitude towards the subject of mathematics but experience difficulties in adapting teaching for gifted students. Teachers describe methods and teaching materials that can be used. These students can be offered acceleration in teaching by working in higher grades, in groups, and with more advanced problem-solving tasks. The conclusion is therefore that teachers distinguish characteristics, organize mathematics teaching and adaptation for particular gifted students. In addition the result of the study shows that teachers also reflect on the challenges and opportunities of teaching in regards to these students.

Introduction Under stormförhållanden kan fartygsrörelser göra det svårt att sova i en säng, då kroppen utsätts för konstanta accelerationer och inklinationer. Hängmattor har en förmåga att agera som en pendel, vilket kan möjliggöra för kroppen att upprätthålla en viloställning som alltid är rätvinklad till horisonten.  Syfte Denna studie syftar till att undersöka om en reduktion av accelerations- och inklinationskrafter som påverkar kroppen under fartygsrörelser kan finnas med användandet av en hängmatta. Metod För att studera dessa krafter användes en kvantitativ forskningsmetod. Data samlades in med hjälp av två mobiltelefoner, utrustade med accelerometrar och inklinometrar och sensorerna placerades i två olika sovsystem: en säng och en hängmatta.  Resultat Resultatet från sensorerna visade att inklinationskrafterna i hängmattan minskade drastiskt med 99% i genomsnitt jämfört med sängen, med en nästan konstant horisontell vinkel på 0°. Dock var accelerationsmätningarna mindre konkreta, med en spridning av acceleration i hängmattan med en minskning på 5%, till en ökning på 21% beroende på experimentstillfälle. Diskussion  Resultaten från denna studie tyder på att hängmattor kan vara ett effektivt sätt att drastiskt minska de inklinationskrafter som sjöfarare utsätts för under fartygsrörelser. Detta kan potentiellt hjälpa sjöfarare uppnå förbättrad sömnkvalitet under dåliga väderförhållanden. Vad gäller accelerationsresultaten kan det tyda på en marginell ökning av accelerationskrafter i hängmatta. Korrelationen mellan sensorerna för accelerationsmätningen var dock endast 82,4%, jämfört med inklinationsmätningens 98,6%. Vidare forskning med mer noggrann mätutrustning krävs för att fastställa någon mer konkret slutsats för acceleration. / Introduction  During storm conditions, ship movements can make it difficult to sleep in a bed, as the body is exposed to constant accelerations and inclinations. Hammocks have the ability to act as a pendulum, allowing the body to maintain a resting position that is always perpendicular to the horizon.  Purpose  This study aims to investigate whether a reduction in acceleration and inclination forces acting on the body during ship movements can be achieved using a hammock. Method  A quantitative research method was employed to study these forces. Data was collected using two mobile phones equipped with accelerometers and inclinometers and the sensors were placed in two different sleeping systems: a bed and a hammock.   Results  The results from the sensors showed that the inclination forces in the hammock decreased significantly by 99% on average compared to the bed, with an almost constant horizontal angle of 0°. However, the acceleration measurements were less concrete, with a spread of acceleration in the hammock between a decrease of 5% to an increase of 21% depending on the experimental occasion. Discussion The results of this study suggest that hammocks may be an effective way to drastically reduce the inclination forces that seafarers are exposed to during ship movements. This could potentially help seafarers achieve improved sleep quality during adverse weather conditions. As for the acceleration results, they may indicate a marginal increase in acceleration forces in the hammock. However, the correlation between the sensors for acceleration measurement was only 82.4%, compared to 98.6% for inclination measurement. Further research with more accurate measuring equipment is required to determine a more definitive conclusion for acceleration.

Inledning: Bandy är en vinterlagsport som innehåller både fysiska och tekniska krav. Till författarnas kännedom finns begränsat med vetenskaplig forskning om bandyspelares fysiska krav under match. Syfte: Syftet med denna studie var att beskriva manliga elitbandyspelares rörelseprofiler utifrån total distans, maximal hastighet, medelhastighet, speltid, hastighetszoner och acceleration under matchsituation mellan olika spelarpositioner. Metod: Datainsamlingen utfördes med tio hertz GPS-enheter på ett elitserielag i bandy från mellersta Sverige under säsongen 2014/15. Sex till åtta manliga elitbandyspelare studerades under elva matchtillfällen. Data analyserades både deskriptivt och genom envägs variansanalys (ANOVA) för att se signifikanta skillnader mellan spelarpositioner. Resultat: Mätningarna visade att spelarpositionen halv uppnådde den längsta totala distansen. Anfall hade den högsta medelhastigheten och utförde flest antal accelerationer per spelad minut. Spelarpositionen libero, back och halv hade den högsta speltiden och det var signifikanta skillnader till mittfält och anfall. Libero och back hade i de två långsammaste hastighetszonerna högst procent av total distans och utförde flest antal aktioner. Halv, mittfält och anfall hade i de två snabbaste hastighetszonerna högst procent av total distans och utförde flest antal aktioner. Slutsats: Detta indikerade att halv, mittfält och anfall hade likande resultat och hade de största fysiska kraven under match jämfört mot libero och back. / Introduction: Bandy is a team winter sport that contains both physical and technical demands. To the authors knowledge there is a limited scientific research on bandy player’s physical demands during the matches. The Aim: The aim of this study was to describe the male elite bandy players movement profiles based on total distance, maximum velocity, mean velocity, game time, velocity zones and acceleration during the match between different playing positions. Method: Data was collected with ten hertz GPS-units in an elite league team in bandy from middle of Sweden during the season 2014/15. Six to eight male elite bandy players were examined during eleven matches. Data were analyzed both descriptive and with one-way analysis of variance (ANOVA) to see significant differences between playing positions. Results: The measurements showed that the playing position half preformed the longest total distance. Forward preformed the highest mean velocity and performed the most number of accelerations per played minute. The playing positions libero, back and half had the highest game time and had significant differences to midfield and forward. Libero and back had the highest percent of the total distance, and performed the highest number of efforts in the two slowest velocity zones. Half, midfield and forward had the highest percent of the total distance and performed the highest number of efforts in the two fastest velocity zones. Conclusion: This indicated that half, midfield and forward had similar results and had the highest physical demands during the game compared to libero and back.

A two-year experimental campaign is described during which diamond-like carbon and plastic targets with thicknesses from 20 nanometers to 15 micrometers were irradiated by the Texas Petawatt Laser. Target composition and thickness were varied to modify the specifics of the laser-matter interaction. Plasma mirrors were selectively implemented to affect the contrast of the laser system and provide additional control of the physical processes under investigation. A number of particle diagnostics were implemented to measure the distribution of laser accelerated ions and electrons. In addition, optical diagnostics were fielded to measure the intensity profile of the laser and measure the density of the target pre-plasma. The results of these experiments suggest that the Texas Petawatt laser pulse has pre-pulse and pedestal features with intensities at least 10⁻⁸ of the main pulse. Micronscale targets were able to survive these features and maintain a relatively sharp density gradient until the arrival of the main laser pulse, allowing for ion acceleration. Electron spectra measured in this configuration show an average temperature of 10 MeV, with no v angular dependence out to at least 60 degrees. By contrast, interferometric plasma density measurements and a lack of any observable ion acceleration suggest that nanoscale targets were destroyed well before the main pulse. In this case, the peak of the laser pulse interacted with a cloud of plasma between 10⁻³ and 10⁻² of critical density. The contrast improvement offered by the implementation of plasma mirrors was seen to increase the maximum energy of laser accelerated protons from targets thicker than 1 micrometer. In addition, the plasma mirrors allowed nanoscale targets to survive pre-pulse and pedestal features and support the production of ion beams. Proton spectra show that ions were accelerated to greater maximum energies from nanoscale targets than from more traditional micron-scale targets. This effect can be attributed to a reduction in the target pre-plasma scale length upon the introduction of plasma mirrors. These results indicate that the manipulation of target properties and laser contrast can significantly affect the interaction between an ultrahigh intensity laser and a target. / text

Accurate single-shot visualization of laser wakefield structures can improve our fundamental understanding of plasma-based accelerators. Previously, frequency domain holography (FDH) was used to visualize weakly nonlinear sinusoidal wakes in plasmas of density n[subscript e] < 0.6 × 10¹⁹/cm³ that produced few or no relativistic electrons. Here, I address the more challenging task of visualizing highly nonlinear wakes in plasmas of density n[subscript e] ~ 1 to 3× 10¹⁹/cm³ that can produce high-quality relativistic electron beams. Nonlinear wakes were driven by 30 TW, 30 fs, 800 nm pump pulses. When bubbles formed, part of a 400 nm, co-propagating, overlapping probe pulse became trapped inside them, creating a light packet of plasma wavelength dimensions--that is, an optical "bullet"--that I reconstruct by FDH methods. As ne increased, the bullets first appeared at 0.8 × 10¹⁹/cm³, the first observation of bubble formation below the electron capture threshold. WAKE simulations confirmed bubble formation without electron capture and the trapping of optical bullets at this density. At n[subscript] >1× 10¹⁹/cm³, bullets appeared with high shot-to-shot stability together with quasi-monoenergetic relativistic electrons. I also directly observed the temporal walk-off of the optical bullet from the beam-loaded plasma bubble revealed by FDH phase shift data, providing unprecedented visualization of the electron injection and beam loading processes. There are five chapters in this thesis. Chapter 1 introduces general laser plasma- based accelerators (LPA). Chapter 2 discusses the FDH imaging technique, including the setup and reconstruction process. In 2006, Dr. N. H. Matlis used FDH to image a linear plasma wakefield. His work is also presented in Chapter 2 but with new analyses. Chapter 3, the main part of the thesis, discusses the visualization of LPAs in the bubble regime. Chapter 4 presents the concept of frequency domain tomography. Chapter 5 suggests future directions for research in FDH. / text

The aim of the submitted diploma thesis is to find and describe how parents look back on the early school attendance in their intellectualy gifted children, what parents led to this decision and what were the reactions of the neighbourhood. The theoretical part of the diploma thesis deals with topics related to the issues of talent, developmental acceleration and premature start of school attendance. The theoretical part is divided into three major parts-the first one is dedicated to talent, its definitions and developmental acceleration and also the relationship between talent, intelligence and heredity. Some models of talents are also mentioned here. The second part deals with the gifted child, its characteristics and asynchrony in its development. The last part focuses on the initiation of education in children with accelerated cognitive development, school maturity and readiness and the possibility of acceleration in education. The practical part is dedicated to qualitative research ivolving parents of six children who started school attendance early and at the same time were intellectually accelerated. Later talent in the intellecutal area was diagnosed in all children based on repeated examination in Pedagogical Psychological Counseling Office.
