Baksidan av svensk rap : - En studie om hegemonisk maskulinitet, utanförskap och levnadförhållnden framställs i svenska raptexter
No full textThe essay focuses on how marginalization, hegemonic masculinity, and the living conditions in the suburbs are constructed in rap lyrics and how they portray lives in the suburb. The purpose of this study is to gain a deeper understanding of the living conditions in the suburb and how Swedish rap artists reflect their lives in songs released between the years 2017-2024. The data used consists of 33 songs from 25 Swedish male rap artists. The essay employs a qualitative method, with the analysis method being textual analysis in the form of content analysis. The theoretical frameworks of this study are the marginalization of groups, living conditions and hegemonic masculinity. The essay's key findings reveal that masculinity and vulnerability are recurring themes and patterns in the analysis. These two themes have contributed to understanding how community has become a crucial focal point for rap artists in the suburb. Another prevalent theme is "Us and them," which arises between the suburb and the wider society, as well as between groups within the suburb.
Frame Factors in the Music Classrum : A Survey Study on How Music Teachers in Middle and Secondary Schools are Affected by Frame Factors
No full textDenna enkätstudie undersöker ett urval av ramfaktorer i musikklassrummet på mellan- och högstadiet samt hur dessa ramfaktorer påverkar musiklärarna i utformandet av lektionsplaneringar i relation till det centrala innehållet. Ramfaktorteorin används i denna studie som ett verktyg för att förstå hur dessa ramfaktorer påverkar musiklärare på mellan- och högstadiet. Den tidigare forskningen och ramfaktorteorin konstaterar att ramfaktorer påverkar lärare på olika sätt och ses både som hinder och möjlighetsskapande. Resultatet pekar på att de musiklärare på mellan- och högstadiet som påverkas av sina ramfaktorer behöver anpassa undervisningen i främst instrumentalundervisning eller musicerande och musikskapande med digitala verktyg. Instrumentalundervisningen kräver anpassning på grund av att undervisningsgruppernas storlekar inte är anpassade efter instrumenttillgång och/eller lektionstiden medan musicerande och musikskapande med digitala verktyg begränsas av antalet datorer eller iPads samt lämplig programvara.
Ofrihet på den fria arbetsmarknaden? : Representationer av tvång vid arbetstillstånd och lönesubventioner i fack- och arbetsgivarpress
No full textLitteraturen om ofritt arbete framhåller perspektivets samtida relevans för att förstå hur arbetsmarknadsrelationer präglas av tvång som både kan vara resultatet av lagbrott och statliga regelverk. I denna artikel undersöks hur svensk fack- och arbetsgivarpress i städ- och restaurangbranscherna representerar tvingande element i samband med arbetsmarknadspolitiska åtgärder och arbetskraftsmigration. Med fokus på rekrytering, utvinning av arbetskraft och utträde analyseras framställningen av beroendeförhållanden och sociala hierarkier vid arbetsrelationens olika moment. Därmed visas hur maktrelationer på arbetsmarknaden kan normaliseras och utmanas i skärningspunkterna mellan statlig reglering, ekonomiska intressen och politiska ställningstagande gällande ”acceptabla” inslag av tvån
Georgia O’Keeffe. : Att närma sig ett konstnärskap.
No full textThe personality of an artist sometimes overwrites the artistry out of curiosity and intent to relate to the person that captivates us so. It also lets us access some sort of content to help us interpret a piece of art where its expression baffles us. It then turns into a form of exotism where what we can´t comprehend about the art translates into a foreign esoterism explained by either madness or other factors that can´t be related to. Out of that we don´t have to say how we feel or lack of what we see as its incomprehensible and so we simply judge by its contents value in terms of realistic depiction, skillful technique or other. This essay is about diverting the person from the art for a truthful and honest approach of the works by Georgia O´Keeffe. With the compositional interpretation method of Gillian Rose, I have approached three works by O´Keeffe before I turned to the biographic analysis of her artistry working from Roxanna Robinsons great biography- Georgia O´Keeffe: A Life, and other scholarly written around her. With the theories of Susan Sontag, I undertook O´Keeffe´s life story with an intent to separate intimate, personal details from current events in her life and actualities that surrounded her. This out of respect for her spoken desire and adamant attitude towards a private life, rejection to explain her work and proud integrity.
Evaluating Distance to the Pith as a Parameter for Strength Grading of Douglas Fir (Pseudotsuga menziesii (Mirb.) Franco)
No full textDistance to the pith is a parameter that is known to be correlated with the mechanical properties of wood, but it is not utilized in strength grading machines. This study aimed to investigate how different the mechanical properties and grading yields are for Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) boards with small and large distances to the pith, respectively, and whether the distance to the pith could be an interesting parameter to use for strength grading in combination with other predictor variables. For this purpose, 221 boards were scanned to obtain fiber orientation and local density. Their dynamic modulus of elasticity and distance to the pith were measured, and they were finally tested in bending. The boards were classified into two categories: corewood if a board’s cross-section was entirely located within a radius of 200 mm from the pith, and outerwood otherwise. The results show that corewood presents lower mechanical properties than outerwood, explained especially by the higher knottiness of corewood. Distance to the pith improves the grading yields of a machine based on fiber orientation measurements, but using the dynamic modulus of elasticity rather than the distance to the pith leads to better results. Distance to the pith can be used as a single or secondary parameter to predict timber strength if the dynamic modulus of elasticity is not used
Warming of shallow temperate lakes : consequences for rotifer community composition and population dynamics
No full textTaxa specific responses to climate warming may shape aquatic communities, dominance patterns, biotic interactions, and related ecosystem processes and functions. As climate warming effects on smaller zooplankton are less understood than larger zooplankton, we focused on rotifers to study their response to a future climate warming scenario in outdoor mesocosms. Our year-long experiment (14 July 2020 to 13 July 2021) included present temperature conditions as controls and a treatment simulating a future warmer climate involving occasional heatwaves. Total rotifer abundance increased with warming, with Keratella spp. and Polyarthra spp. benefiting the most, while the Kellicottia spp. population collapsed. Filinia spp. were negatively affected by warming in the summer of 2020, but increased during winter and the following summer. Our findings suggest that thermophilic or eurytherm rotifers such as Keratella and Polyarthra may increase in a warmer future, while heat-sensitive Kellicottia may be negatively affected in the temperate region. Milder winters may allow some rotifer genera to proliferate while allowing others to recover from high summer temperatures, thereby considerably changing the composition and dominance patterns of rotifer assemblages
Fältsekreterare i territoriellt stigmatiserade områden : En kvalitativ studie om stigma och förebyggande arbete
No full textI denna studie undersöks vilka utmaningar fältsekreterare beskriver, samt vilka strategier de återger i sitt arbete i territoriellt stigmatiserade områden. Studien har en kvalitativ ansats och bygger på semistrukturerade intervjuer med fältsekreterare verksamma i olika svenska städer. Syftet är att undersöka hur fältsekreterare upplever och hanterar arbetet i dessa områden, med särskilt fokus på hur de reflekterar över stigmatiseringens betydelse för ungdomar, vilka möjligheter och svårigheter de ser i det förebyggande arbetet, samt vad de upplever saknas för att detta arbete ska bli mer effektivt. I intervjuerna berättar fältsekreterarna om sina erfarenheter av hur stigmatiseringen påverkar ungdomars självbild och framtidstro, samt hur de arbetar förebyggande för att skapa trygga mötesplatser och relationer. De beskriver även hinder i det förebyggande arbetet, såsom begränsade resurser och bristande samverkan mellan olika aktörer. Fältsekreterarna lyfter särskilt fram betydelsen av trygga vuxna, tillgång till meningsfulla fritidsaktiviteter och möjligheter till arbete som viktiga faktorer för att stärka ungdomars förutsättningar.
Photoperiods and light differentially influence growth and potential niches of phycocyanin- and phycoerythrin-rich picocyanobacteria
No full textStrains from the picocyanobacteria genus Synechococcus are currently found across a wide range of photoperiods and photosynthetically active radiation. Future scenarios now forecast range expansions of marine Synechococcus into new photic regimes. We found that strains of temperate, coastal phycocyanin-rich and phycoerythrin-rich Synechococcus grew fastest under moderate photosynthetically active radiation, and a 24-h photoperiod, despite a cumulative diel photon dose equivalent to conditions where growth was slower, under higher light and shorter photoperiods. Under optimal conditions, a phycoerythrin-rich Synechococcus strain achieved a highest recorded cyanobacterial chlorophyll-specific exponential growth rate (mu) of 4.5 d-1. Two phycoerythrin-rich strains demonstrated wider ability to modulate light capture capacity, whereas two phycocyanin-rich strains showed less change in light capture across increasing cumulative diel photon dose. All four coastal strains showed a decrease of effective absorption cross-section for photosystem II photochemistry, vs. increasing cumulative diel photosynthetically active radiation doses. Within each strain, mu showed consistent, saturating responses to increasing cumulative diel photosystem II electron flux, with more variations in responses of mu to cumulative photosynthetically usable radiation. As photoperiod opportunists, coastal picocyanobacteria show potential to expand into longer photic regimes as higher latitudes warm
Behandling av tuberkulos : Effekten av vitamin D vid profylaktisk behandling eller standardbehandling
No full textSammanfattning Tuberkulos (TB) är en av de tio mest dödliga sjukdomarna och den vanligaste dödliga infektionssjukdomen i världen. Det uppskattas att ca en fjärdedel av världens befolkning är smittad av bakterien men i Sverige är infektionen under kontroll tack vare smittskyddslagen. Sjukdomen orsakas av Mycobacterium tuberculosis som kan finnas i kroppen i latent eller aktiv form. Individer med latent TB är asymtomatiska och inte smittsamma medan individer med aktiv TB är smittsamma och uppvisar symtom som hosta, feber och nattliga svettningar. Den är en behandlingsbar folksjukdom som oftast angriper lungorna men kan också uppstå i andra organ. Vid latent TB behandlas patienter med isoniazid som monoterapi eller i kombination av isoniazid (INH) och rifampin (RIF). Vid aktivt TB behandlas patienterna i förstahand med INH, RIF, pyrazinamide (PZA) och ethambutol (EMB) under första två månader och fortsätter med INH och RIF i ytterligare fyra månader (totalt minst sex månader). Behandlingen kan förlängas vid resistensutveckling eller svår sjukdom. Det sker ständigt forskning för att förbättra behandlingstiden och hitta nya metoder. Ett aktivt forskningsområde är tillskott av vitamin D antingen profylaktiskt eller som tillägg vid basbehandling. Vitamin D är sedan länge känt för sin roll i immunförsvaret och kan ha en immunmodulerande effekt vid TB. Syftet med detta litteraturarbete är att undersöka effekten av vitamin D som profylaktisk samt som tillägg vid behandling av TB. Arbetet är baserat på fem publicerade randomiserade kliniska prövningar. Dessa fem studier undersökte effekten av vitamin D jämfört vid profylaktiskt eller standardbehandling. Studierna hade inte starka bevis som kunde tyda till att använda vitamin D som profylaktiskt och som tillägg vid TB behandling. Några av studierna hade lovande resultat på förbättring av sjukdomsbehandling där bland annat resultatet av studie 4 och 5 visade en ökad konvertering av positiv sputum-prov, ökad medelvikt och längd. Alla studier visade också på ökad nivå av vitamin D i serum hos deltagarna i vitamin D grupperna. Det behövs dock mer forskning eftersom studierna i detta arbete har olika svagheter, så som få deltagare, kort uppföljningstid och olika doser av vitamin D. Det skulle behövas större och mer noggranna studier för att kunna säga om vitamin D hjälper vid TB, och till vilka patienter. Det vill säga om det har mer nytta hos barn, vuxna, sjukdomssvårighet, kön, osv.Tuberculosis (TB) is one of the deadliest infectious diseases that is prevalent in the world. It has been an epidemic that has not been eliminated despite the disease having existed for several generations. About a quarter of the world's population might likely be infected with the bacterium. In Sweden, the infection is controlled by the strict protocol of the Infection Control Act. Individuals who migrate to Sweden are usually examined for the disease and treated if necessary. The disease is caused by Mycobacterium tuberculosis, causing infection in the body either in latent or active form. Individuals with latent TB are asymptomatic and are not contagious, while individuals with active TB are contagious and show symptoms such as cough, fever, and night sweating. It is a treatable, widespread disease that most often affects the lungs but can also occur in other organs. Patients with latent TB are treated with isoniazid as monotherapy or in combination with rifampin. Patients with active TB are primarily treated with a combination of isoniazid, rifampin, pyrazinamide, and ethambutol during the first two months, followed by isoniazid and rifampin for an additional four months, which in total is at least six months. For some patients, the treatment could be extended in cases where patients have developed drug resistance or have severe disease. Scientists are constantly researching to identify novel ways to improve treatment strategies. Recent research is investigating the potential role of vitamin D as a prophylactic agent or as a supplement to standard TB treatment to improve treatment outcomes. The purpose of this literature work is to investigate the effect of vitamin D as a prophylactic and as a supplement in the treatment of tuberculosis. This work is based on five randomized clinical trials retrieved from the PubMed database. These five studies investigated the effect of vitamin D compared to placebo, both as a prophylactic and adjunct to standard TB treatment. The studies did not provide strong evidence to support the use of vitamin D for prevention or as an additional treatment for TB. However, some of the studies showed promising results regarding disease improvement. The findings from studies 4 and 5 show an increased conversion rate of positive sputum samples as well as improvement in average weight and height. All studies also reported increased serum vitamin D levels among participants in the vitamin D groups. Nevertheless, further research is necessary to establish if vitamin D has a role in the treatment or prophylaxis of tuberculosis
Commentary on "Consumed by Creed"
No full text"Consumed by Creed" is a research article that suggests a link between obsessive-compulsive symptoms and support for political violence. Analyzing the article and the data set provided by the authors, we found errors in their methodology and procedures, accompanied by a high degree of researcher freedom that could have led to the finding of false-positive results. Given the important political and psychological implications of the claimed findings and the weakness of the evidence presented, we recommend substantial caution in interpreting the results reported in the article, and we urge researchers to drastically improve current research practices in the field of radicalization to ensure that policy decisions are based on valid and reliable evidence
