- Students in engineering are well trained in solving specified problems, but some have trouble when given problems where there is more than one solution. In their professional life they are much more often confronted with open-ended problems, where there may be more than one solution, and where there may be many ways to reach each one. The goals may be vague, the problem may be underspecified, and the fresh graduate frustrated by the new situation.We present a structured approach to training students in open-ended problem solving. We have introduced a half-day workshop to help students learn to work with open-ended, ill-structured problems, using a different approach than they would for the well-structured problems they are used to.Our results indicate that students have become more creative. Compared to previous years, the students explore more paths towards the goal, and use more elaborate methods. Their approach is similar to that typically used by the best students in previous instances of the course. Students mention creativity and group dynamics as positive aspects of the workshop and the following lab.We conclude that with proper guidance and training, even weaker students can become more creative when solving open-ended problems.

Stenbruk : Stenartefakter, råmaterial och mobilitet i östra Mellansverige under tidig- och mellanmesolitikum
- 2018
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis examines artefacts, raw materials and lithic technology between c. 9200–6200 cal BC in Eastern Central Sweden. The overall purpose of this study is to investigate when people first came to Eastern Central Sweden and where they came from. More precisely, it provides a typological, geographical and chronological survey of artefacts and the use of different raw materials. The study deals with assemblages with artefacts from more than thirty archaeologically excavated sites and loose finds in Eastern Central Sweden. The objects consist of chubby pecked axes, core axes, flake axes, shaft hole picks, microliths and micro burins, points, burins, rulers, unifacial blade core, conical cores, micro blade cores, blades, drills, retouched blades and micro blades. The artefacts have been compared with established typologies and chronologies for the rest of the Nordic countries and to some extent Russia and the Baltic States. An analysis of different raw materials present at Early and Middle Mesolithic sites in Eastern Central Sweden was also carried out. The materials are put into a chronological and geographical context. The raw materials included in the study are the non-local rocks flint and Cambrian flint, as well as local raw materials such as quartz, greenstone, local vulcanite, mylonite and red porphyry. From 9200 cal BC there is evidence of the first groups of people in the area, just shortly after that the Weichselian ice cap had withdrawn. Throughout the period studied the artefacts as well as the non-local raw materials exhibit great similarities to those found in the western part of Sweden. The study also shows, regarding the use of different raw materials and presence of certain artefacts, that some major events took place, suggesting a new chronological time frame for the Early- and Middle Mesolithic periods. In addition, a discussion regarding mobility and migration in Eastern Central Sweden during Early Post Glacial time is carried out.

Arkeologiska förväntningar i mötet med ett landskap : Stenålderns Blekinge ur ett kunskapsperspektiv
- 2019
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study is about archaeological knowledge production. It is also about what kind of impact such knowledge may have on an antiquarian/archaeological practice as well as on society as a whole. The work focuses broadly on Stone Age archaeology and specifically on the middle-Mesolithic Age in the county of Blekinge in the South East of Sweden.Until the late 1990’s, large-scale archaeological excavations in this region were rare. In particular, there were significant gaps in early- and middle-Mesolithic archaeology of other regions. In particular, the study brings up the relationship with the defined Kongemose culture's settlements in Southern Scandinavia. From a knowledge perspective the study discusses how different kinds of methodological practices are important for both archaeology and society, to be able to see and understand a more complete historical picture. Based on this, the focus shifts the role of museums within regional archaeology. The study here argues for a more strategically executed dissemination and presentation of archaeological knowledge towards different stakeholders.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To assess patient-reported outcome measures (PROMs), aesthetics and stability of root coverage procedures from a previous 6-month RCT after 1year. Material & Methods: Forty-five patients (90 recessions) had received a coronally advanced flap (CAF=control) only or a xenogeneic collagen matrix in addition (CAF+CMX=test). Visual analogue scales (VAS) and questionnaires were used for PROMs and the root coverage aesthetic score (RES) for professional aesthetic evaluations. Results: VAS scores (patient satisfaction) amounted to 8.58±1.86 (test) versus 8.38±2.46 (control). Six patients preferred CAF+CMX concerning surgical procedure and aesthetics, six preferred CAF and 29 were equally satisfied. RES was 7.85±2.42 for the test group versus 7.34±2.90 for the controls. Root coverage (RC) was 76.28% for test and 75.05% for control defects. The mean increase in keratinized tissue width was higher in test (from 1.97 to 3.02mm) than in controls (from 2.00 to 2.64 mm) (p=0.0413). Likewise, test sites showed more gain in gingival thickness (0.52mm) than control sites (0.27mm) (p=0.0023). Compared to 6months, clinical outcomes were stable. Conclusions: Results for PROMs, RES and RC did not significantly differ between treatment groups. Thickness and width of keratinized tissue were enhanced following CAF+CMX compared to CAF alone. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd
