Skolverkets bedömningsstöd i matematik för årskurs 1 - en multipel fallstudie i två kommuner

Nyckelord: Skolverkets bedömningsstöd i matematik, systematiskt kvalitetsarbete, kartläggning, tidiga insatser, matematiksvårigheter Abstract Syfte Studiens syfte har varit att synliggöra det arbete som sker på förvaltningsnivå, skolnivå och lärarnivå med Skolverkets bedömningsstöd i matematik för åk 1, som blev obligatoriskt att genomföra 2016, och därmed ge en bild av hur kartläggningens resultat används i det systematiska kvalitetsarbetet på alla nivåer i utbildningsorganisationen. Eftersom bedömningsstödet är ett relativt nytt kartläggningsmaterial var ytterligare ett syfte att undersöka hur skolor organiserar arbetet med bedömningsstödet för att identifiera elever i matematiksvårigheter samt få kunskap om vilka insatser som görs utifrån resultaten. Teori Studien är huvudsakligen baserad på ett kommunikativt och relationsinriktat perspektiv som kan användas för att studera samspelet mellan skolan som organisation och den enskilde elevens förutsättningar för kunskapsutveckling. En teoretisk utgångspunkt togs även i det sociokulturella perspektivet där lärande sker genom kommunikation och i samspel med andra. Metod Utifrån studiens syfte valdes en multipel fallstudie som forskningsansats. Som metod användes semistrukturerade intervjuer. Urvalet bestod av sex skolor uppdelade på två kommuner. 14 intervjuer genomfördes med yrkesgrupper från olika nivåer i utbildningsorganisationen. Verksamhetschef, kvalitets-utvecklare, rektorer och lärare deltog i studien. Resultat I studien framkommer att det är lärare som genomför kartläggningen av elevers matematikkunskaper med hjälp av bedömningsstödet i matematik för årskurs 1. Resultatet visar att den specialpedagogiska kompetensen delvis används i analysen av resultaten på kartläggningen. Vidare framkommer att bedömningsstödet kan ge elever i matematik-svårigheter ökade möjligheter att utvecklas i matematik då åtgärder sätts in tidigt på gruppnivå, i form av en kvalitativ undervisning som förändrat

Vad finns under ytan?

Sedan mitten av 1940-talet har Fiskeriverkets Sötvattenslaboratorium provfiskat sjöar i olika delar av Sverige. Sedan mitten av 1980-talet har provfiskena i första hand utförts i kalkade sjöar för att följa fiskbeståndens utveckling efter kalkning. I början av 1990-talet utökades verksamheten till att omfatta även referenssjöar som ej skulle vara påverkade av någon lokal föroreningskälla. Detta för att detektera biologiska förändringar som beror av mer diffusa orsaker som t ex klimatförändringar och en ändrad deposition av luftföroreningar. Följande rapport redovisar resultaten från de 37 sjöar som provfiskades under år 2003 och innehåller en övergripande del samt en utvärdering av resultaten från varje sjö

Inhaling salbutamol may decrease time to exhaustion in some contexts of heavy endurance performances.

PURPOSE: To study the effect of inhaling a beta-agonist (salbutamol) compared to placebo on skiing and cycling performance in well-trained elite athletes. METHODS: Three different exercise protocols were used, all with a cross-over double blind placebo-controlled design. Participants inhaled 800 µg salbutamol or a placebo prior to the test, which was repeated on a following day with the participants inhaling the other substance. Fifteen junior elite skiers performed four free-style high intensity sprints (1100 m/work time 3.5-4.5 min). Twelve elite cyclists carried out a short cycling protocol, starting with two 5 min submaximal workloads followed by a maximal intermittent performance test to exhaustion. Another 12 elite cyclists performed the maximal intermittent performance test to exhaustion after a 150 min long submaximal cycling protocol. RESULTS: Group mean time for the ski sprints increased, with no difference between treatment groups. In the short cycling protocol time to exhaustion was 9.1% (95% CI 52-161) lower after inhaling salbutamol compared to placebo and in the long cycling protocol time to exhaustion was 9.1% (95% CI - 121-267) lower after inhaling salbutamol compared to placebo. Blood lactate, heart rate and ventilation increased during submaximal exercise with salbutamol compared to placebo in the short cycling protocol (p < .05). CONCLUSION: This study could not confirm any positive performance effects from inhaling 800 µg salbutamol compared to placebo in skiing and high-intensity intermittent cycling performance. Instead, time to exhaustion in the maximal intermittent performance test was lower in both cycling protocols. HighlightsThere was no difference in performance time between salbutamol and placebo treatment in real-life applicable repeated ski sprints.Time to exhaustion in the maximal intermittent performance test was 9.1% lower after inhaling salbutamol compared to placebo, both when performed after 10 and 150 min of submaximal cycling

Closure after gastrostomy button

A gastrostomy device is removed from the gastrostoma when no longer needed. The aim of the study was to test the hypothesis of whether it is possible for the surgeon to decide which stoma has to be closed with a gastroraphy and which to leave for a spontaneous closure within a reasonable period of time. Out of a cohort of 321 patients, who had been operated with a video-assisted gastrostomy, we included all the 48 patients having had their gastrostomy button removed. These patients were carefully followed and the closure of the gastrostoma was registered. According to the institutional routine we waited at least 3 months after the removal of the gastrostomy device before suggesting to the child's guardians an operative closure of the stoma. In 26 patients the stoma closed within 3 months, whereas in 22 patients a surgical gastroraphy was performed. We found no differences between the two groups regarding the patients' diagnoses, the duration of the gastrostoma use or patient's age at the time of removal of the gastrostomy device. This study rejected the hypothesis of predictability of the gastrostoma closure. Thus, we recommend a routine expectance after the removal of a gastrostomy device for at least 1 month. If no spontaneous closure occurs, then a gastroraphy should be performed

Multicentre phase II trial of capecitabine and oxaliplatin in combination with radiotherapy for unresectable colorectal cancer: The CORGI-L study.

AIMS: This study assessed radiotherapy combined with capecitabine and oxaliplatin in patients with primary, inextirpable colorectal adenocarcinoma. PATIENTS AND METHODS: Forty-nine patients entered the trial. Two cycles of XELOX (capecitabine 1000mg/m(2) bid d1-14+oxaliplatin 130mg/m(2) d1, q3w) were followed by radiotherapy (50.4Gy), combined with capecitabine 825mg/m(2) bid every radiotherapy day and oxaliplatin 60mg/m(2) once weekly. The primary end-point was objective response. RESULTS: Forty-seven patients were evaluable. Twenty-nine (62% [95% CI: 46-75%]) achieved complete or partial response. Thirty-eight (81%) went through surgery of whom 37 (97%) had an R0 resection and five (13%) had a pathological complete response. Seventy-eight percent were alive and estimated local progression rate was 11% at 2 years. The most common grade 3+ toxicity during chemoradiotherapy was diarrhoea (24%). CONCLUSIONS: XELOX-RT was feasible and showed promising efficacy when treating patients with primary inextirpable colorectal cancer, establishing high local control rate

Effects of winter tyres : state of the art

Choice of winter tyres has, from mainly being a matter of safety and economic costs for wearing of road pavements, during later years also become a matter of inhalable particles formed during pavement wear from studded tyres and their negative effects on public health. Further, the tyres' effects on environment and noise have been illustrated in several studies. The issue is also complicated by the fact that tyre choice effects on traffic safety have several components, including such diverging parameters as friction and behaviour. Finally all aspects have to be evaluated from a socioeconomic point of view for society to be able to decide which kind of distribution of tyre types that is the most profitable. This report is a summary of current knowledge in this complex research field.Valet av vinterdäck har, från att i huvudsak varit en fråga om trafiksäkerhet och slitage av vägar under senare år även kommit att handla om negativa effekter av de inandningsbara partiklar som bildas då dubbdäck sliter på vägbanan och de effekter på befolkningens hälsa som dessa partiklar har. Vidare har vägslitagets inverkan på miljön genom spridning av bl.a. tungmetaller belysts liksom däckvalets betydelse för bullerproblematiken. Frågan kompliceras ytterligare av att däckvalets betydelse för trafiksäkerheten har många beståndsdelar inkluderande såväl tekniska parametrar, t.ex. friktion, som beteendevetenskapliga aspekter. I slutändan måste alla dessa aspekter vägas samman samhälls-ekonomiskt för att den för samhället mest lönsamma däckanvändningen skall kunna uppnås. Denna rapport belyser kunskapsläget inom detta komplexa problemområde

Nanocellulose composite wound dressings for real-time pH wound monitoring

The skin is the largest organ of the human body. Wounds disrupt the functions of the skin and can have catastrophic consequences for an individual resulting in significant morbidity and mortality. Wound infections are common and can substantially delay healing and can result in non-healing wounds and sepsis. Early diagnosis and treatment of infection reduce risk of complications and support wound healing. Methods for monitoring of wound pH can facilitate early detection of infection. Here we show a novel strategy for integrating pH sensing capabilities in state-of-the-art hydrogel-based wound dressings fabricated from bacterial nanocellulose (BC). A high surface area material was developed by self-assembly of mesoporous silica nanoparticles (MSNs) in BC. By encapsulating a pH-responsive dye in the MSNs, wound dressings for continuous pH sensing with spatiotemporal resolution were developed. The pH responsive BC-based nanocomposites demonstrated excellent wound dressing properties, with respect to conformability, mechanical properties, and water vapor transmission rate. In addition to facilitating rapid colorimetric assessment of wound pH, this strategy for generating functional BC-MSN nanocomposites can be further be adapted for encapsulation and release of bioactive compounds for treatment of hard-to-heal wounds, enabling development of novel wound care materials.Validerad;2023;Nivå 2;2023-03-03 (hanlid);Funder: Swedish Government Strategic Research Area in Materials Science on Functional Materials at Linköping University (SFO-Mat-LiU no. 2009–00971)</p
