Syftet med undersökningen är att med avseende på skolans genusuppdrag studera musiklärares förhållningsätt i ensembleundervisning på gymnasieskolan. För att uppnå detta har kvalitativa, semistrukturerade intervjuer genomförts med lärare i gymnasiekursen ensemble, följt av diskursanalys på transkriberingar av dessa intervjuer. De teoretiska utgångspunkterna är genusteorier och diskursteorier. I resultatet framkommer lärarnas syn på genusbegreppet och genusuppdraget. Bland de genusdiskurser som presenteras finns synen på genus som rutin, som sidoeffekt på annat arbete och som medvetenhet. Gällande elevsyn visar sig diskurser om eleven som platstagare, som normbrytare och vikten av att eleven känner sig som en synbar individ. Slutledningarna, liksom diskussionskapitlet, rör sig kring genusarbetets framgångar, vilka faktorer som kan ha orsakat dessa, och hur arbetet förändrats på skolorna utifrån dessa framgångar. Genomgående har ett individfokus framkommit, där eleverna inte ses som en grupp, utan som enskilda individer, vilka alla måste mötas personligt.

The permeability of dispersion barriers produced from polyvinyl alcohol (PVOH) and kaolin clay blends coated onto polymeric supports has been studied by employing two different measurement methods: the oxygen transmission rate (OTR) and the ambient oxygen ingress rate (AOIR). Coatings with different thicknesses and kaolin contents were studied. Structural information of the dispersion-barrier coatings was obtained by Fourier transform infrared spectroscopy (FTIR) spectroscopy and scanning electron microscopy (SEM). These results showed that the kaolin content influences both the orientation of the kaolin and the degree of crystallinity of the PVOH coating. Increased kaolin content increased the alignment of the kaolin platelets to the basal plane of the coating. Higher kaolin content was accompanied by higher degree of crystallinity of the PVOH. The barrier thickness proved to be less important in the early stages of the mass transport process, whereas it had a significant influence on the steady-state permeability. The results from this study demonstrate the need for better understanding of how permeability is influenced by (chemical and physical) structure.

BACKGROUND: Errors in the decision-making process are probably the main threat to patient safety in the prehospital setting. The reason can be the change of focus in prehospital care from the traditional "scoop and run" practice to a more complex assessment and this new focus imposes real demands on clinical judgment. The use of Clinical Guidelines (CG) is a common strategy for cognitively supporting the prehospital providers. However, there are studies that suggest that the compliance with CG in some cases is low in the prehospital setting. One possible way to increase compliance with guidelines could be to introduce guidelines in a Computerized Decision Support System (CDSS). There is limited evidence relating to the effect of CDSS in a prehospital setting. The present study aimed to evaluate the effect of CDSS on compliance with the basic assessment process described in the prehospital CG and the effect of On Scene Time (OST). METHODS: In this time-series study, data from prehospital medical records were collected on a weekly basis during the study period. Medical records were rated with the guidance of a rating protocol and data on OST were collected. The difference between baseline and the intervention period was assessed by a segmented regression. RESULTS: In this study, 371 patients were included. Compliance with the assessment process described in the prehospital CG was stable during the baseline period. Following the introduction of the CDSS, compliance rose significantly. The post-intervention slope was stable. The CDSS had no significant effect on OST. CONCLUSIONS: The use of CDSS in prehospital care has the ability to increase compliance with the assessment process of patients with a medical emergency. This study was unable to demonstrate any effects of OST.

The purpose of this study was to establish the optimal allometric models to predict International Ski Federation’s ski-ranking points for sprint competitions (FISsprint) among elite female cross-country skiers based on maximal oxygen uptake (V̇O2max) and lean mass (LM). Ten elite female cross-country skiers (age: 24.5±2.8 years [mean ± SD]) completed a treadmill roller-skiing test to determine V̇O2max (ie, aerobic power) using the diagonal stride technique, whereas LM (ie, a surrogate indicator of anaerobic capacity) was determined by dual-emission X-ray anthropometry. The subjects’ FISsprint were used as competitive performance measures. Power function modeling was used to predict the skiers’ FISsprint based on V̇O2max, LM, and body mass. The subjects’ test and performance data were as follows: V̇O2max, 4.0±0.3 L min-1; LM, 48.9±4.4 kg; body mass, 64.0±5.2 kg; and FISsprint, 116.4±59.6 points. The following power function models were established for the prediction of FISsprint: 3.91×105 ∙ VO -6.002maxand 6.95×1010 ∙ LM-5.25; these models explained 66% (P=0.0043) and 52% (P=0.019), respectively, of the variance in the FISsprint. Body mass failed to contribute to both models; hence, the models are based on V̇O2max and LM expressed absolutely. The results demonstrate that the physiological variables that reflect aerobic power and anaerobic capacity are important indicators of competitive sprint performance among elite female skiers. To accurately indicate performance capability among elite female skiers, the presented power function models should be used. Skiers whose V̇O2max differs by 1% will differ in their FISsprint by 5.8%, whereas the corresponding 1% difference in LM is related to an FISsprint difference of 5.1%, where both differences are in favor of the skier with higher V̇O2max or LM. It is recommended that coaches use the absolute expression of these variables to monitor skiers’ performance-related training adaptations linked to changes in aerobic power and anaerobic capacity.

Anhörigomsorg är del av en komplex väv med olika nivåer, individuella, familjemässiga och övergripande samhälleliga, där åtminstone de senare har begränsade resurser. Denna rapport presenterar och diskuterar kunskapsläget inom svensk och internationell forskning om anhöriga till äldre. Vi sätter den svenska anhörigomsorgen i ett större sammanhang genom resonemang om demografiska förutsättningar, historiska tillbakablickar och internationella utblickar. Nutid belyses med aktuella undersökningar och vi tror att framtiden kan klaras tack vare den allt större överlappning vi redan ser mellan många olika former av hjälp, service, omsorg och vård. Vi ställer frågan om dessa mönster kanske förbises i de ofta dystra, rent demografisk-ekonomiska framskrivningarna. Rapporten redovisar många svenska undersökningar av anhörigomsorg, både i befolkningen i stort och bland äldre. Det förefaller klart att det skett en faktisk ökning av anhörigomsorgens omfattning från 1990-talet och början av 2000- talet, något som flera studier visar. Resultat från en europeisk undersökning med gemensamma frågor och svarsalternativ tyder på att anhörigomsorg är vanligare i Nordeuropa än i Sydeuropa vilket nog strider mot gängse föreställningar. Kanske är det i Norden vanligare att vara hjälpgivare men inte med lika omfattande engagemang eller lika länge och man bor sällan tillsammans. Då fördelas nog omsorgen på fler händer. I Sverige angav mindre än 1 procent att de gav omsorg på heltid, i Spanien 5 procent. Sammantaget har, i Sverige liksom i övriga Europa, mer än 4 av 10 i befolkningen en aktuell eller tidigare personlig erfarenhet av att ge omsorg, och på befolkningsnivå är anhörigomsorgen klart större än den offentliga. De flesta svenska studier visar att det är ungefär lika vanligt bland kvinnor och män att vara givare av anhörigomsorg. Kvinnor ger dock oftare personlig omvårdnad och de ger fler timmar omsorg än männen. De flesta omsorgsgivare ger ganska få hjälptimmar, men timinsatserna ökar med stigande ålder och är högst bland de äldsta. I genomsnitt ger omkring 30 procent av omsorgsgivarna daglig hjälp, men den andelen stiger till nästan 40 procent för anhörigvårdare i 65–80 årsåldern och till 80 procent för dem som är ännu äldre. Äldre utgör således 30 procent av alla som ger omsorg, oftast till andra äldre, men utför ungefär 4 av 10 omsorgstimmar. Äldre personer är inte bara mottagare av omsorg utan minst lika ofta också givare. De flesta givare av anhörigomsorg ger ”lättare” former av insatser (skjutsning, passning, tillsyn etc.), insatser som många gånger säkerligen är viktiga och kan vara avgörande för mottagaren. Det är viktigt att se det stora spektret av anhörigomsorg och att det också finns grupper av anhöriga (ofta äldre personer) som gör omfattande insatser som kan påverka såväl egen hälsa som arbetsliv. Vid små hjälpbehov – fallet för de flesta – får man lite hjälp främst av anhöriga, vid större behov mer hjälp och då av både anhöriga och av kommunen. Delat ansvar är vanligt och även vad omsorgsgivare och mottagare önskar. Få önskar bära ansvaret ensamma och få önskar att ansvaret helt ligger på det offentliga. Historiskt utgör barn och andra anhöriga en viss trygghet på ålderdomen, något som inte tillhör det förflutna, utan snarare kommer att få större betydelse framöver. Anledningen är demografisk: allt fler har nära anhöriga i form av en egen familj. Familjens relativa betydelse har ökat, inte minskat som man ibland föreställer sig. Detta accentueras av att den offentliga omsorgen visserligen är väl utbyggd i Sverige, men tycks ha nått gränsen för vad den kan uträtta, praktiskt och finansiellt. Anhörigomsorgen har även socialpolitiska aspekter. Den som är eller varit anhörigvårdare vill helst inte själv vara mottagare av omfattande anhörigvård, utan hellre få huvuddelen av omsorgen från det offentliga. Man kan nog förutse ännu strängare ransonering av offentliga tjänster i framtiden, där anhöriga och marknadsbaserade tjänster är alternativen, möjligen tillsammans med växande insatser från ideella organisationer.

  The general aim of this dissertation is to describe and analyse patterns of informal care and support for carers in Sweden. One specific aim is to study patterns of informal care from a broad population perspective in terms of types of care and types of carer. A typology of four different care categories based on what carers do revealed that women were much more likely than men to be involved at the ‘heavy end’ of caring, i.e. providing personal care in combination with a variety of other caring tasks. Men were more likely than women to provide some kind of practical help (Study I). Another aim is to investigate which support services are received by which types of informal caregiver. Relatively few informal caregivers in any care category were found to be receiving any kind of support from municipalities or voluntary organizations, for example training or financial assistance (Study II). The same study also examines which kinds of help care recipients receive in addition to that provided by informal carers. It appears that people in receipt of personal care from an informal caregiver quite often also receive help from the public care system, in this case mostly municipal services. However, the majority of those receiving personal, informal care did not receive any help from the public care system or from voluntary organizations or for-profit agencies (Study II). The empirical material in studies I and II comprises survey data from telephone interviews with a random sample of residents in the County of Stockholm aged between 18 and 84. In a number of countries there is a growing interest among social scientists and social policymakers in examining the types of support services that might be needed by people who provide informal care for older people and others. A further aim of the present dissertation is therefore to describe and analyse the carer support that is provided by municipalities and voluntary organizations in Sweden. The dissertation examines whether this support is aimed directly or indirectly at caregivers and discusses whether the Swedish government’s special financial investment in help for carers actually led to any changes in the support provided by municipalities and voluntary organisations. The main types of carer support offered by the municipalities were payment for care-giving, relief services and day care. The chief forms of carer support provided by the voluntary organizations were support groups, training groups, and a number of services aimed primarily at the elderly care recipients (Study III). Patterns of change in municipal carer support could be discerned fairly soon. The Swedish government’s special allocation to municipalities and voluntary organisations appears to have led to an increase in the number of municipalities providing direct support for carers, such as training, information material and professional caregiver consultants. On the other hand, only minor changes could be discerned in the pattern of carer support services provided by the voluntary organizations. This demonstrates stability and the relatively low impact that policy initiatives seem to have on voluntary organizations as providers (Study IV). In studies III and IV the empirical material consists of survey data from mail questionnaires sent to municipalities and voluntary organizations in the County of Stockholm. In the fields of social planning and social work there appears to be a need to clarify the aims of support services for informal carers. Should the support be direct or indirect? Should it be used to supplement or substitute caregivers? In this process of reappraisal it will be important to take the needs of both caregivers and care recipients into account when developing existing and new forms of support. How informal caregivers and care recipients interact with the care system as a whole is undeniably a fertile field for further research.

This article deals with the notion of belonging in today’s multi-ethnic Sweden and hints at perpectives of future European identity-building. On the basis of Frantz Fanon’s understanding of colonialism and the colonized mentality as theoretical, the article deals with the situation of Roma in Sweden – and Europe. With the story of a young Roma woman that has migrated to Sweden from Hungary as point of departure, the article addresses the situation for Romani people, but also for other migrants in Europe, with particular focus on who are allowed to belong to the community of Swedish and European citizens, and who are not

Different metabolic pathways of supplemental and fortification Fe, or inhibition of Zn absorption by Fe, may explain adverse effects of supplemental Fe in Fe-sufficient infants. We determined whether the mode of oral Fe administration or the amount habitually consumed affects Fe absorption and systemic Fe utilisation in infants, and assessed the effects of these interventions on Zn absorption, Fe and Zn status, and growth. Fe-sufficient 6-month-old infants (n 72) were randomly assigned to receive 6·6 mg Fe/d from a high-Fe formula, 1·3 mg Fe/d from a low-Fe formula or 6·6 mg Fe/d from Fe drops and a formula with no added Fe for 45 d. Fractional Fe absorption, Fe utilisation and fractional Zn absorption were measured with oral (57Fe and 67Zn) and intravenous (58Fe and 70Zn) isotopes. Fe and Zn status, infection and growth were measured. At 45 d, Hb was 6·3 g/l higher in the high-Fe formula group compared with the Fe drops group, whereas serum ferritin was 34 and 35 % higher, respectively, and serum transferrin 0·1 g/l lower in the high-Fe formula and Fe drops groups compared with the low-Fe formula group (all P<0·05). No intervention effects were observed on Fe absorption, Fe utilisation, Zn absorption, other Fe status indices, plasma Zn or growth. We concluded that neither supplemental or fortification Fe nor the amount of Fe habitually consumed altered Fe absorption, Fe utilisation, Zn absorption, Zn status or growth in Fe-sufficient infants. Consumption of low-Fe formula as the only source of Fe was insufficient to maintain Fe stores.

Viticulture is an activity of great social and economic importance in the lower-middle region of the São Francisco River valley in northeastern Brazil. In this region, the fertility of soils under vineyards is generally poor. To assess the effects of organic and nitrogen fertilization on chemical properties and nitrate concentrations in an Argissolo Vermelho-Amarelo (Typic Plinthustalf), a field experiment was carried out in Petrolina, Pernambuco, on Syrah grapevines. Treatments consisted of two rates of organic fertilizer (0 and 30 m3 ha-1) and five N rates (0, 10, 20, 40, and 80 kg ha-1), in a randomized block design arranged in split plots, with five replications. The organic fertilizer levels represented the main plots and the N levels, the subplots. The source of N was urea and the source of organic fertilizer was goat manure. Irrigation was applied through a drip system and N by fertigation. At the end of the third growing season, soil chemical properties were determined and nitrate concentration in the soil solution (extracted by porous cups) was determined. Organic fertilization increased organic matter, pH, EC, P, K, Ca, Mg, Mn, sum of bases, base saturation, and CEC, but decreased exchangeable Cu concentration in the soil by complexation of Cu in the organic matter. Organic fertilization raised the nitrate concentration in the 0.20-0.40 m soil layer, making it leachable. Nitrate concentration in the soil increased as N rates increased, up to more than 300 mg kg-1 in soil and nearly 800 mg L-1 in the soil solution, becoming prone to leaching losses.
