Tidskriftsartikel (refereegranskat)abstract
- Essential for detection of relevant external stimuli and for fear processing, the amygdala is under modulatory influence of dopamine (DA). The DA transporter (DAT) is of fundamental importance for the regulation of DA transmission by mediating reuptake inactivation of extracellular DA. This study examined if a common functional variable number tandem repeat polymorphism in the 3' untranslated region of the DAT gene (SLC6A3) influences amygdala function during the processing of aversive emotional stimuli. Amygdala reactivity was examined by comparing regional cerebral blood flow, measured with positron emission tomography and [(15)O]water, during exposure to angry and neutral faces, respectively, in a Swedish sample comprising 32 patients with social anxiety disorder and 17 healthy volunteers. In a separate US sample, comprising 85 healthy volunteers studied with blood oxygen level-dependent functional magnetic resonance imaging, amygdala reactivity was assessed by comparing the activity during exposure to threatening faces and neutral geometric shapes, respectively. In both the Swedish and the US sample, 9-repeat carriers displayed higher amygdala reactivity than 10-repeat homozygotes. The results suggest that this polymorphism contributes to individual variability in amygdala reactivity.

Leve idrottspedagogiken : En vänbok tillägnad Lars-Magnus Engström
- 2005
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Vem ägnar sig åt idrott? Vilken betydelse har fritiden i barns och ungdomars liv? Vad innebär hälsa i skolämnet idrott och hälsa?Leve idrottspedagogiken! tillägnas Lars-Magnus Engström. Texterna i boken speglar delar av det idrottspedagogiska forskningsområdet i Sverige, vars framväxt Lars-Magnus Engström varit den främste företrädaren för. Läsaren får här ta del av exempelvis idrottskulturen, fritidskulturen och skolans ämne idrott och hälsa. Genomgående handlar texterna om villkoren för barns och ungdomars deltagane och om de olika lärprocesser som sker i anslutning till idrottsutövning.Lars-Magnus Engström har gjort betydande insatser som forskare och lärare samt som professor vid Lärarhögskolan i Stockholm och vid Gymnastik- och idrottshögskolan. I snart fyrtion år har han arbetat med studier kring påverkans- och lärprocesser i idrott. Hans forskning har främst kretsat kring människors idrottsvanor och vilka som utvecklar en fysiskt aktiv livsstil. Idrotts- och motionsutövningar ger både ett så kallat egenvärde och investeringsvärde. Med dessa begrepp bland många andra har Lars-Magnus Engström bidragit till en fördjupad vetenskaplig förståelse av idrottskulturen.De flesta författarna har eller har haft Lars-Magnus Engström som handledare och tillhör forskningsgruppen för pedagogik, idrott och fritidskultur. Redaktörer för boken är Karin Redelius och Håkan Larsson.

Towards social well-being in schools : an implementation study of Involvement Education
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The first purpose of this thesis concerning the implementation of Involvement Education (IE) was to highlight the experiences of the most important actors in the school (teachers, pupils and administration) when implementing the method in ordinary classes /leisure-time centers in a Swedish compulsory school, grades 1-6.IE is presented as a theory and a method, with the purpose of fostering sound self-esteem in human beings, stimulate a friendly social climate, training of positive traits or “virtues” and teaching positive ways of handling conflict. Its main strategy consists of group talks with the participants sitting in a close circle. There are different kinds of talks each with a different structure of leadership. Of great importance is the attitude of the adult and his/her ability to lead the talks. Theoretically IE is based upon ideas from William Glasser, Alfred Adler and Aron Antonovsky.The second purpose was to study how the implementation process per se was experienced and how the process developed over time. Did the use of IE continue and develop without support from ”outside”?The approach chosen is the phenomenon-oriented case study. The study was done during a period of three years involving students, staff and administration. Quantitative as well as qualitative methods have been used.The findings indicate that IE was experienced as being in line with the curricula of the school and of the recreation center concerning students’ socio-emotional development. The findings also indicate that the teachers experienced that IE was a method that could positively stimulate the social competence of the students, unity in the class, develop the ability to handle conflicts and develop attention of good qualities.The students liked the talks and experienced that the participants listened to them when they spoke. Several students said that they had been better to solve conflicts. These findings were analyzed from a theoretical point of view that stressed the necessity of satisfying certain basic psychological needs in order to develop social skills.Concerning the second purpose the findings indicate that the method was successfully implemented in the school. In the leisure-time centers, however, the method was not implemented. One reason was that the pedagogy in leisure-time centers traditionally has not stressed the worth of structured activities.In the concluding chapter some implications of the study for further research are discussed as well as IE in regard to some fundamental issues concerning didactics and schooling. Among these are: what can be learned from a study like this? – IE and the situation in today’s schools in Sweden and consequences for teacher training.
