Konstuniversitetet
No full textHögskoleutbildningarna inom det konstnärliga området är mångfasetterade och täcker många konstformer inom musik, dans, teater, cirkus, bild, foto, design, konsthantverk, textil, arkitektur, skrivande, för att bara nämna några. Uttrycken är publika, ofta förankrade i historia och tradition men även i ständig omförhandling med rådande samhällsdiskurser och kulturpolitik. Med boken Konstuniversitetet , fördjupas perspektiven kring de pedagogiska, konstnärliga men även organisatoriska utmaningarna inom konstutbildning. En permanent dualism mellan inre växande och yttre krav gör lärande och utbildande inom konst till en ömtålig verksamhet. För utbildaren gäller det att betrakta, förstå, utveckla och stödja – men utan att störa. En fördel är då att det konstnärliga lärandet sker i relationer och att samtal är den vanligaste undervisningsmetoden. Även detta måste dock problematiseras och detta görs på olika sätt i denna antologi. Boken har fyra huvuddelar: konsten, samhället, praktiken och lärande.

Effect of sprint cycle training on activities of antioxidant enzymes in human skeletal muscle
No full text Hellsten, Ylva, Fred S. Apple, and Bertil Sjödin.Effect of sprint cycle training on activities of antioxidant enzymes in human skeletal muscle. J. Appl. Physiol. 81(4): 1484–1487, 1996.—The effect of intermittent sprint cycle training on the level of muscle antioxidant enzyme protection was investigated. Resting muscle biopsies, obtained before and after 6 wk of training and 3, 24, and 72 h after the final session of an additional 1 wk of more frequent training, were analyzed for activities of the antioxidant enzymes glutathione peroxidase (GPX), glutathione reductase (GR), and superoxide dismutase (SOD). Activities of several muscle metabolic enzymes were determined to assess the effectiveness of the training. After the first 6-wk training period, no change in GPX, GR, or SOD was observed, but after the 7th week of training there was an increase in GPX from 120 ± 12 (SE) to 164 ± 24 μmol ⋅ min−1 ⋅ g dry wt−1( P < 0.05) and in GR from 10.8 ± 0.8 to 16.8 ± 2.4 μmol ⋅ min−1 ⋅ g dry wt−1( P < 0.05). There was no significant change in SOD. Sprint cycle training induced a significant ( P < 0.05) elevation in the activity of phosphofructokinase and creatine kinase, implying an enhanced anaerobic capacity in the trained muscle. The present study demonstrates that intermittent sprint cycle training that induces an enhanced capacity for anaerobic energy generation also improves the level of antioxidant protection in the muscle. </jats:p

The Degree Project: An Evaluation from Within
No full textThis chapter builds on a quality assessment of my teaching during the preparation seminars for the ‘degree project’ at the Malmö Academy of Music (hereafter: MAM). The evaluation is extended to review the way the course functioned on the basis of John Biggs’ (2003) theories on ‘constructive alignment’. As a result, this chapter also problematises the design of such coursework at a broader structural level while at the same time suggesting future initiatives for the ongoing development of Higher Music Education (hereafter: HME)
Advances and challenges in skeletal muscle angiogenesis.
No full textThe role of capillaries is to serve as the interface for delivery of oxygen and removal of metabolites to/from tissues. During the past decade there has been a proliferation of studies that have advanced our understanding of angiogenesis demonstrating tissue capillary supply is under strict control during health, but poorly controlled in disease - resulting in either excessive capillary growth (pathological angiogenesis) or losses in capillarity (rarefaction). Given that skeletal muscle comprises nearly 40% of body mass in humans, skeletal muscle capillary density has a significant impact on metabolism, endocrine function, and locomotion, and is tightly regulated at many different levels. Skeletal muscle is also high adaptable, and thus one of the few organ systems which can be experimentally manipulated (e.g. by exercise) to study physiologic regulation of angiogenesis. This review will focus on 1) the methodological concerns that have arisen in determining skeletal muscle capillarity, and 2) highlight the concepts that are reshaping our understanding of the angio-adaptation process. We also summarize selected new findings (physical influences, molecular changes and ultrastructural rearrangement of capillaries) that identify areas of future research with the greatest potential to expand our understanding of how angiogenesis is normally regulated, and that may also help to better understand conditions of uncontrolled (pathologic) angiogenesis
