Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on sibling interaction and children’s everyday media practices in their homes. Ten sibling pairs, aged four to nine years, have been followed in their homes during a six-month period with media ethnographic methods. The data mainly consist of video recorded sibling interactions.The thesis draws on sociocultural theories, cultural sociological perspectives and insights from social interaction research. The analyses are grounded in the social interaction and meaning making acts that take place in media activities in the home settings. However they also extend to a broader societal context, in order to show how social structure and social action are constantly interwoven in children’s lives.The thesis documents how the media represent an important part of the child's everyday culture. Media create key reference frames and common platforms for the children’s games and play activities. The siblings use media and various artifacts to negotiate, challenge or assume desirable positions. Media artefacts can also be used as a way to present oneself.The younger siblings progressively work their way into the older siblings’ media landscapes, and the elder siblings become guides or role models in handling video games, music, and YouTube activities. In addition to purely practical skills when it comes to handling the technical equipment, the older siblings also mediate local taste hierarchies, norms, and values.The thesis also describes how children are social actors who interpret and reinterpret the constant ongoing movements in the media landscape. Moreover, the thesis highlights how consumption is closely linked to media practices. Mobiles, games consoles and membership on virtual gaming sites become highly valued phenomena and status markers in children’s media worlds.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents two case studies that suggest how to adapt Scrum for user-centered design (UCD) focused industrial projects and how to work with UCD in Scrum software development teams. The objective of the paper is to share insights gained from running such combined projects in industry in order to help others avoid some of the pitfalls associated with this way of working. There has been much published in this area within the research community. However, our work presents both perspectives: adapting a UCD way of working towards a Scrum way of working; and adapting Scrum for running projects from a UCD perspective. We explore the impact Scrum had on team members’ work-practices during a project life-cycle and what lessons were learned from our experiences.

Att växa sidledes : Tematik, barnsyn och konstnärlig gestaltning i Suzanne Ostens scenkonst för unga

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to highlight and discuss the artistic force, potential and significance of performing arts for children and young audiences through the example of the work by Suzanne Osten. The focus of this research is on themes, notions of the child and artistic expressions and strategies. The dissertation discusses both the aesthetic and the political aspects of Osten’s theatre for young audiences and takes an interdisciplinary approach, combining theatre and performance studies and childhood studies. A fundamental assumption is that childhood is not a fixed or stable phase that manifests itself in one particular way for all children during all times. Another assumption is that theatre is more than what is visually apparent on stage. What is staged does not take place inside a vacuum, but is closely connected to the surrounding society and culture. To study theatre for young audiences as a cultural expression is therefore, to a great extent, also about analysing notions of the child.Five performances have been selected, all for young audiences: Paddakvariet (The Toad Aquarium, 1988, for ages 10 and over), Delfinen (The Dolphin, 1992, for ages 3 and over), Irinias nya liv (Irina’s New Life, 1996, for ages 9 and over), Flickan, mamman och soporna (The Girl, the Mother and the rubbish, 1998, for ages 7 and over), and Lammungarnas fest (The Baa-lambs Holiday, 2014, for ages 13 and over). A model for performance analysis has been constructed, based on hermeneutics and semiotics, complemented by three key theoretical concepts. Firstly focalization, as used by theatre scholar Maaike Bleeker, in order to understand the interaction between the spectator and the visions produced by the apparatus of performance. The reasoning of theatre scholar Gay McAuley about space in performance is used to examine how space is utilized and retained in the performances, while the notion of utopian performative by theatre scholar Jill Dolan provides tools to discuss how moments of ‘feeling utopia’ are a significant part of the selected works which raises questions of the transformative and affective power of theatre. In order to contextualize and historicise the analyses, the response of the performances is also taken into account drawing mainly on theatre reviews.As a whole the analyses show Osten’s theatre for young audiences as an ongoing research project problematizing the situation and position of children in society, as well as the view of art for children. Ostens performances for young audiences exhibit and make possible notions of a child outside of the norm in late 20th and early 21st century childhood discourses both within research and society as a whole. Osten’s theatre and artistry are identified as growing sideways, developing in unexpected directions while disrupting ideas about childhood and adulthood, and also what can be viewed as theatre for children and theatre for adults. The dissertation states that Osten’s theatre for young audiences can be seen as pioneering, not only in the field of children’s theatre, but also for the development and renewal of Swedish theatre in general.

Tidskriftsartikel (refereegranskat)abstract
- Background: Optimizing calf muscle performance seems to play an important role in minimizing impairments and symptoms after an Achilles tendon rupture (ATR). The literature lacks long-term follow-up studies after ATR that describe calf muscle performance over time. Purpose: The primary aim was to evaluate calf muscle performance and patient-reported outcomes at a mean of 7 years after ATR in patients included in a prospective, randomized controlled trial. A secondary aim was to evaluate whether improvement in calf muscle performance continued after the 2-year follow-up. Methods: Sixty-six subjects (13 women, 53 men) with a mean age of 50 years (SD, 8.5 years) were evaluated at a mean of 7 years (SD, 1 year) years after their ATR. Thirty-four subjects had surgical treatment and 32 had nonsurgical treatment. Patient-reported outcomes were evaluated with Achilles tendon Total Rupture Score (ATRS) and Physical Activity Scale (PAS). Calf muscle performance was evaluated with single-leg standing heel-rise test, concentric strength power heel-rise test, and single-legged hop for distance. Limb Symmetry Index (LSI = injured side/healthy side x 100) was calculated for side-to-side differences. Results: Seven years after ATR, the injured side showed decreased values in all calf muscle performance tests (P < .001-.012). Significant improvement in calf muscle performance did not continue after the 2-year follow-up. Heel-rise height increased significantly (P = .002) between the 1-year (10.8 cm) and the 7-year (11.5 cm) follow-up assessments. The median ATRS was 96 (of a possible score of 100) and the median PAS was 4 (of a possible score of 6), indicating minor patient-reported symptoms and fairly high physical activity. No significant differences were found in calf muscle performance or patient-reported outcomes between the treatment groups except for the LSI for heel-rise repetitions. Conclusion: Continued deficits in calf muscle endurance and strength remained 7 years after ATR. No continued improvement in calf muscle performance occurred after the 2-year follow-up except for heel-rise height.

- The early stages of rehabilitation appear to be of great importance for outcome after an Achilles tendon rupture. It is a challenge to evaluate the patients’ calf muscle endurance at this stage in a safe and adequate way. The aim of our study was to develop a seated heel-rise test suitable for evaluating calf muscle endurance three months after an Achilles tendon rupture. Furthermore we wanted to evaluate how the seated heel-rise test correlated to the ability to perform one-legged standing heel-rise and patient-reported symptoms. Method: Ninety-three patients, 79 men and 14 women, mean age of 40 (20-63) years, were included from a cohort of 100 patients participating in a prospective, randomized controlled trial comparing non-surgical and surgical treatment after Achilles tendon rupture. Forty-seven were treated with surgery and 46 with non-surgery. They were evaluated after 3, 6 and 12 months. Patient reported outcome was evaluated with Achilles Tendon Rupture Score (ATRS) and functional outcome with seated and standing heel-rise test. The seated heel-rise test was performed with the patient sitting with hip and knee in 90°. A leg extension weight-training machine was used to provide load onto the patient’s thigh at 50% body weight. The limb symmetry index (LSI=injured/healthy x 100) was calculated in order to compare the results from the seated and standing heel-rise test. Results: Ninety-one patients out of 93 (98%) could perform the seated heel-rise test. At the 3-month follow-up there was a significant difference (p<0.01) in the seated heel-rise test between the injured and the healthy side. There were no significant differences between the surgical and non-surgical treatment groups. There were significant differences in the seated heel-rise test and in ATRS (p<0.01) when comparing the group who could perform a standing heel-rise test at the 3-months follow-up, with the group who could not. There were significant correlations between the LSI-values in the seated heel-rise height at the 3-month follow-up and the standing heel-rise height at the 6-month (r=0.36, p<0.001, n= 91) and the 12-month follow-up (r=0.35, p=0.001, n=85). There were also significant correlations (r=0.22-0.37, p=<0.04) between the seated heel-rise test and ATRS. Conclusions: The seated heel-rise-test has the capacity to identify differences between the injured and the healthy side three months after injury. This test also correlates with patient reported outcomes and the heel-rise ability at 6 and 12 months. This test appears to be a safe and suitable test for evaluating calf muscle endurance and function in the early stages of rehabilitation after an Achilles tendon rupture.

- It is still unknown why many patients never fully recover after an Achilles tendon rupture (ATR). The aim of this study was to perform a long-term follow-up (5-9 years) of patients treated either surgically or non-surgically after an ATR. Furthermore, we wanted to examine if the patients had a tendon elongation on the injured side and evaluate if this correlated to function, symptoms and foot structure. Material and Method Sixty-seven patients (13 women) mean age of 50 years were evaluated 5-9 years after injury. Thirty-five patients were treated with surgery and 32 with non-surgery. Patient reported outcome and activity level, lower leg function, tendon length, and foot-structure were evaluated. Both the healthy and the injured side were examined and the limb symmetry index (LSI=injured/healthy x 100) was calculated. Results There were significant differences between the healthy and injured side in all function tests (p<0.001-0.015) and the tendon was significantly longer on the injured side (p<0.001) independent of treatment. There were no significant correlations between tendon length and patient reported outcome, function or foot structure. The heel-rise height increased significantly (p<0.000) from the 1 year- to the 5-9-years-follow up. The mean Achilles tendon Total Rupture Score (ATRS) was 91/100, indicating minor symptoms. Conclusion: Patients with an Achilles tendon rupture continues to have significant deficits in tendon structure and function 5-9 years after injury. There is, however continued improvement between the 1 and 5-9 year follow-up.

- The purpose of this study was to evaluate calf muscle endurance in a seated position 3 months after an Achilles tendon rupture and to evaluate how the ability to perform standardized seated heel-rises correlated to the single-leg standing heel-rise test and to patient-reported symptoms evaluated with the Achilles tendon Total Rupture Score (ATRS) 3 and 6 months after the injury. Ninety-three patients were included from a cohort of 101 patients participating in a prospective, randomized controlled trial comparing surgical and nonsurgical treatment after Achilles tendon rupture. Forty-seven patients were treated surgically and 46 nonsurgically. Ninety-one patients out of 93 (98%) could perform the standardized seated heel-rises. At the 3-month follow-up, there was a significant difference (P<0.001) between the injured and the healthy side performing standardized seated heel-rises. There were also significant correlations (r=0.29-0.37, P=<0.05) between the standardized seated heel-rises and ATRS 3 and 6 months after injury in the group who could not perform single-leg standing heel-rises. There were no significant differences between the surgical and nonsurgical treatment groups. The evaluation of standardized seated heel-rises appears to be a useful tool to quantify progress and predict future functional performance and patient-reported symptoms.

- Achilles tendon rupture leads to weakness of ankle plantarflexion. Treatment of Achilles tendon rupture should aim to restore function while minimizing weakness and complications of management.To determine the influence of factors (age, sex, body mass index [BMI], weight, time from injury to operative repair, and tightness of repair) in the initial surgical management of patients after an acute Achilles tendon rupture on 12-month functional outcome assessment after percutaneous and minimally invasive repair.Cohort study; Level of evidence, 3.From May 2012 to January 2018, patients sustaining an Achilles tendon rupture receiving operative repair were prospectively evaluated. Tightness of repair was quantified using the intraoperative Achilles tendon resting angle (ATRA). Heel-rise height index (HRHI) was used as the primary 12-month outcome variable. Secondary outcome measures included Achilles tendon total rupture score (ATRS) and Tegner score. Stepwise multiple regression was used to create a model to predict 12-month HRHI.A total of 122 patients met the inclusion criteria for data analysis (mean ± SD age, 44.1 ± 10.8 years; 78% male; mean ± SD BMI, 28.1 ± 4.3 kg/m2). The elapsed time to surgery was 6.5 ± 4.0 days. At 12-month follow-up, patients had an HRHI of 82% ± 16% and performed 82% ± 17% of repetitions compared with the noninjured side. Participants had a mean ATRS of 87 ± 15 and a median Tegner score of 5 (range, 1-9), with a reduction in Tegner score of 2 from preinjury levels. The relative ATRA at 12 months was -4.8° ± 3.9°. Multiple regression identified younger age (B = ±0.006; P < .001) and greater intraoperative ATRA (B = 0.005; P = .053) as predictors of more symmetrical 12-month HRHI (R2 = 0.19; P < .001; n = 120).Age was found to be the strongest predictor of outcome after Achilles tendon rupture. The most important modifiable risk factor was the tightness of repair. It is recommended that repair be performed as tight as possible to optimize heel-rise height 1 year after Achilles tendon rupture and possibly to reduce tendon elongation.
