Pragmatic investigation : studies of meaning-making in educational practices
- 2008
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- The overall aim of this paper is to present and discuss a pragmatic approach for studies of meaning-making in different educational practices. The approach – built on a framework developed within the SMED-group (Studies of Meaning-making in Educational Discourses) at the universities of Uppsala and Örebro – is illustrated in a number of empirical studies. The main point of departure in the studies is taken in pragmatic curriculum theory and sociocultural perspectives on learning, and is inspired mainly by John Dewey, Ludwig Wittgenstein and Michel Foucault. A special focus is directed to communication practices and content selection within Physical education, Environmental education and Science education. A common ambition is to offer a language that enables studies and discussions on questions concerning how meanings are made in people’s actions. Another ambition is to make these investigations beyond assumptions of dualisms, essentialism, causality and determinism. In this perspective learning and socialisation is viewed in communicative perspective. Therefore, many of the studies are built on video recorded classroom conversations, but also on analysis of various kinds of written texts. We argue in the paper that this approach makes it possible to study meaning-making – learning and socialisation – in different kinds of educational practices.

- The overall aim of the article is to present a pragmatic approach for studies of meaning-making used in the articles of this issue. The approach, which is developed within the SMEDgroup (Studies of Meaning-making in Educational Discourses), mainly builds on the writings of John Dewey, Ludwig Wittgenstein and Michel Foucault. A common ambition for the researchers in SMED is to enable studies and discussions on questions concerning how meanings are made in people’s actions. Another ambition is to carry out these studies beyond assumptions of dualism, essentialism, causality and determinism. In this perspective learning and socialization are viewed in a communicative perspective. We argue in the article that our approach makes it possible, and important, to study meaning-making in action in different kinds of educational practices.

- We investigated changes in a large battery of pro- and anti-inflammatory cytokines in elite female soccer players following two 90-min games separated by a 72-h active or passive recovery. Blood samples were taken from 10 players before, within 15-20 min, 21, 45 and 69 h after the first game and within 15-20 min after the second game. The leukocyte count was analyzed, together with several plasma pro- and anti-inflammatory cytokines, using a multiplex bead array system. After the first and second game, the total leukocytes and neutrophils increased significantly. Likewise, increases (P<0.05) in pro-inflammatory cytokines [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (INF-gamma), IL-17], chemokines [monocyte chemotactic protein-1 (MCP-1), IL-8 and monokine induced by gamma interferon (MIG)], anti-inflammatory cytokines (IL-2R, IL-4, IL-5, IL-7, IL-10, IL-13, INF-alpha) and the mixed cytokine IL-6 were observed. Leukocyte and cytokine levels were normalized within 21 h. Active recovery (low-intensity exercises) did not affect the cytokine responses. A dampened cytokine response was observed after the second game as only IL-12, IL-6, MCP-1, IL-8 and MIG increased (P<0.05). In conclusion, a robust pro- and anti-inflammatory cytokine response occurs after the first but not the second soccer game. The implications of the dampened cytokine response in female players after the second game are unknown.

- The aim of the present study was to examine the movement patterns, ball skills, and the impressions of Swedish elite football players during competitive games on artificial turf and natural grass. Time - motion analyses (36 observations) and technical analyses (16 team observations) were performed and 72 male and 21 female players completed a questionnaire. No differences were observed between artificial turf and natural grass in terms of total distance covered (mean 10.19 km, s = 0.19 vs. 10.33 km, s = 0.23), high-intensity running (1.86 km, s = 0.10 vs. 1.87 km, s = 0.14), number of sprints (21, s = 1 vs. 22, s = 2), standing tackles (10, s = 1 vs. 11, s = 1) or headers per game (8, s = 1 vs. 8, s = 1), whereas there were fewer sliding tackles (P < 0.05) on artificial turf than natural grass (2.1, s = 0.5 vs. 4.3, s = 0.6). There were more short passes (218, s = 14 vs. 167, s = 12) and midfield-to-midfield passes (148, s = 11 vs. 107, s = 8) (both P < 0.05) on artificial turf than natural grass. On a scale of 0-10, where 0 = "better than", 5 = "equal to", and 10 = "worse than", the male players reported a negative overall impression (8.3, s = 0.2), poorer ball control (7.3, s = 0.3), and greater physical effort (7.2, s = 0.2) on artificial turf than natural grass. In conclusion, the running activities and technical standard were similar during games on artificial turf and natural grass. However, fewer sliding tackles and more short passes were performed during games on artificial turf. The observed change in playing style could partly explain the male players' negative impression of artificial turf.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To investigate the time course of recovery from neuromuscular fatigue and some biochemical changes between two female soccer matches separated by an active or passive recovery regime. METHODS: Countermovement jump (CMJ), sprint performance, maximal isokinetic knee flexion and extension, creatine kinase (CK), urea, uric acid, and perceived muscle soreness were measured in 17 elite female soccer players before, immediately after, 5, 21, 45, 51, and 69 h after a first match, and immediately after a second match. Eight players performed active recovery (submaximal cycling at 60% of HRpeak and low-intensity resistance training at < 50% 1RM) 22 and 46 h after the first match. RESULTS: In response to the first match, a significant decrease in sprint performance (-3.0 +/- 0.5%), CMJ (-4.4 +/- 0.8%), peak torque in knee extension (-7.1 +/- 1.9%) and flexion (-9.4 +/- 1.8%), and an increase in CK (+ 152 +/- 28%), urea (15 +/- 2), uric acid (+ 11 +/- 2%), and muscle soreness occurred. Sprint ability was first to return to baseline (5 h) followed by urea and uric acid (21 h), isokinetic knee extension (27 h) and flexion (51 h), CK, and muscle soreness (69 h), whereas CMJ was still reduced at the beginning of the second match. There were no significant differences in the recovery pattern between the active and passive recovery groups. The magnitude of the neuromuscular and biochemical changes after the second match was similar to that observed after the first match. CONCLUSION: The present study reveals differences in the recovery pattern of the various neuromuscular and biochemical parameters in response to a female soccer match. The active recovery had no effects on the recovery pattern of the four neuromuscular and three biochemical parameters.

Plasma antioxidant responses and oxidative stress following a soccer game in elite female players
- 2010
-
Ingår i: Scandinavian Journal of Medicine and Science in Sports. - Malden, USA : Wiley-Blackwell. - 0905-7188 .- 1600-0838. ; 20:4, s. 600-608

Tidskriftsartikel (refereegranskat)abstract
- We aimed to investigate markers of oxidative stress and levels of endogenous and dietary antioxidants in 16 elite female soccer players in response to a 90-min game (average intensity 82+/-3% HRpeak). Blood samples were taken before, immediately and 21 h after the game. Plasma-oxidized glutathione, the ratio of reduced to oxidized glutathione (GSH:GSSG) and lipid peroxidation measured by d-ROMs were used as markers of oxidative stress. Plasma endogenous [uric acid, total glutathione (TGSH)] and dietary antioxidants (alpha-tocopherol, ascorbic acid, total carotenoids and polyphenols) were analyzed using liquid chromatography and the Folin-Ciocalteu method. Exercise induced an acute increase (P<0.05) in GSSG, uric acid, TGSH, alpha-tocopherol, and ascorbic acid. In parallel, the GSH:GSSG ratio and polyphenols decreased (P<0.05). GSSG, GSH:GSSG ratio, uric acid, TGSH, and ascorbic acid returned to baseline at 21 h, while polyphenols and alpha-tocopherol remained altered. Total carotenoids increased above baseline only at 21 h (P<0.05). Lipid peroxidation, measured by d-ROMs, remained unchanged throughout the study. Thus, intermittent exercise in well-trained female athletes induces a transient increase in GSSG and a decrease in the GSH:GSSG ratio, which is effectively balanced by the recruitment of both endogenous and dietary antioxidants, resulting in the absence of lipid peroxidation measured by d-ROMs.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- I stadslandskapet manifesteras människans makt över naturen. Staden är dynamisk; den skapas och omskapas ständigt i takt med förändrade politiska och kulturella ideal. Dess olika miljöer används – medvetet och omedvetet – för olika typer av lärande. Skolgården och slottsparken kan fungera som budbärare med pedagogiska avsikter för både barn och vuxna, gallerian kan ses som ett klassrum och detaljhandeln som kunskaps- och kulturformande faktorer. När olika grupper intar det offentliga rummet uppstår nya mötesplatser och samspelsmönster. Ser det sociala samspelet likadant ut i förorten, på handelsgatan och i innerstaden? Hur och när tar exempelvis unga kvinnor staden i besittning?
