Conference paper (peer-reviewed)abstract
- Today, innovation is a key word for many universities, as it constitutes an important part of most universities’ public and scientific outreach task. Many universities are striving to increase the number of innovations generated at the university. A common method is to provide various support for research projects e.g.; providing researchers with information about international patent rights (IPR), offering administrative or financial help concerning patent applications, giving entrepreneurship and start-up support, etc. However, fostering innovators and entrepreneurs can start already in undergraduate/graduate courses, i.e. long before a student potentially reaches the research level. We believe that key factors for success in this matter are diversity and freedom. A course that strives to promote innovation capability must allow for students with different backgrounds and different curricula to meet and work together, and must allow for students to freely use their current knowledge within new contexts. This is generally not a setting provided in traditional undergraduate/graduate courses. This article describes the execution and outcome of an graduate course “international Market-Driven Engineering (iMDE)” in which diversity and freedom are key factors. The course is international and multi-disciplinary in terms of students, teachers and subjects. Graduate students with prior knowledge in automatic control constitute one important part of the course population. We believe that the diversity amongst the students, and their freedom when it comes to both innovation process and product, provides a promising platform in which seeds of ideas can grow into conceptual prototypes that build a solid foundation for full-scale innovations. On of the iMDE- projects, the Elderly Accessible Chair, or EA Chair, with its automated scanning and automatic seat- provider functionality, is one concrete example of this.

Metacognition and Learning Journals in Higher Education
- 2013
-
In: International Journal of Economics and Management Engineering. - 2226-7344. ; 3:4, s. 152-159
-
Journal article (peer-reviewed)abstract
- The studies in higher education have its natural focus on the subject matters of study. This also holds for the master program Technology Management (TM). In addition it is important to complement the students’ academic knowledge with insights about metacognition, i.e. knowledge and understanding of themselves and their own behaviour. The introduction of so-called Learning Journals has proved to be a successful step in this direction. TM is a unique program at Lund University, where a selected number (40) of students from the Faculty of Economics (20) and from the Faculty of Engineering (20) are taught together during their last 2 years of study. Their different views on problems and challenges in today’s industry often complement each other. By the introduction of learning journals, they also learn about themselves, what influence their motivation, behaviour and attitude have on a group, and an understanding of their own preferred learning method. The learning journals are introduced in the course Project Leadership. In this course, the students are divided in groups of 4-5 students, each one managing one project. Throughout the whole course (2 semesters) the students are writing learning journals and supervisors are commenting monthly. The learning journals have four purposes; 1) providing an opportunity to reflect on the development of the project itself 2) enabling personal reflection on the own process, 2) enabling reflection on the own position and part in the group, and 4) through the longitudinal effect of the course; it provides an opportunity to compare journals over time to become aware of and able to analyse the own learning process. In a newly performed Placement report, students that have graduated from the Technology Management programme the last 10 years, rate their education 4.37 out of 5. Some students even consider the Learning Journals among the most valuable parts of the whole programme in retrospect.

Conference paper (peer-reviewed)abstract
- Technology Management is a unique program at Lund University, where a selected number (40) of students from the Faculty of Economics and from the Faculty of Engineering are taught together during their last 2 years of study. Their degree will be a Master's degree. Their views on problems and challenges in today's industry often complement each other. In addition it is important to complement their academic knowledge with insights about themselves and their own behavior. The introduction of so-called Learning Journals has proved to be a successful step in this direction. The learning journals are introduced in the course Project Leadership.

A sexual ornament in chickens is affected by pleiotropic alleles at HAO1 and BMP2, selected during domestication.
- 2012
-
In: PLoS genetics. - : Public Library of Science (PLoS). - 1553-7404 .- 1553-7390. ; 8:8
-
Journal article (peer-reviewed)abstract
- Domestication is one of the strongest forms of short-term, directional selection. Although selection is typically only exerted on one or a few target traits, domestication can lead to numerous changes in many seemingly unrelated phenotypes. It is unknown whether such correlated responses are due to pleiotropy or linkage between separate genetic architectures. Using three separate intercrosses between wild and domestic chickens, a locus affecting comb mass (a sexual ornament in the chicken) and several fitness traits (primarily medullary bone allocation and fecundity) was identified. This locus contains two tightly-linked genes, BMP2 and HAO1, which together produce the range of pleiotropic effects seen. This study demonstrates the importance of pleiotropy (or extremely close linkage) in domestication. The nature of this pleiotropy also provides insights into how this sexual ornament could be maintained in wild populations.

The role of pleiotropy and linkage in genes affecting a sexual ornament and bone allocation in the chicken.

Journal article (peer-reviewed)abstract
- Sexual selection and the ornaments that inform such choices have been extensively studied, particularly from a phenotypic perspective. Although more is being revealed about the genetic architecture of sexual ornaments, much still remains to be discovered. The comb of the chicken is one of the most widely recognized sexual ornaments, which has been shown to be correlated with both fecundity and bone allocation. In this study, we use a combination of multiple intercrosses between White Leghorn populations and wild-derived Red Junglefowl to, first, map quantitative trait loci (QTL) for bone allocation and, second, to identify expression QTL that correlate and colocalize with comb mass. These candidate quantitative genes were then assessed for potential pleiotropic effects on bone tissue and fecundity traits. We identify genes that correlate with both relative comb mass and bone traits suggesting a combination of both pleiotropy and linkage mediates gene regulatory variation in these traits.

Short-Term Psychological Outcomes in Severely Obese Adolescents After Bariatric Surgery.
- 2012
-
In: Obesity. - : Wiley. - 1930-7381 .- 1930-739X. ; 20:2, s. 318-323

Journal article (peer-reviewed)abstract
- Bariatric surgery is suggested as a treatment option for severely obese adolescents. Because adolescence is characterized by intense psychosocial adjustment and development, it is important to study the effect of this procedure on adolescents' psychological health. This study examined baseline status and short-term changes in anxiety, depression, anger, disruptive behavior, and self-concept in 37 adolescents (mean age 16.6 ± 1.3). Participants completed the Beck Youth Inventories (BYI) at inclusion and (on average) 4 months after undergoing Roux-en-Y gastric bypass (RYGB). Internalizing (anxiety and depression) and externalizing (anger and disruptive behavior) symptoms were higher at baseline than gender-specific norms. One fifth had a very low self-concept. Four months after surgery, the adolescents showed significantly fewer symptoms of anxiety and depression and significantly improved self-concept from baseline. Anger and disruptive behavior showed no significant changes. An analysis of clinically meaningful changes was conducted, and besides the overall positive outcome, 16% (n = 6) of the adolescents had deteriorated on two or more inventories in BYI shortly after surgery. This impaired group did not show any specific features at inclusion. The results indicate the importance of psychological monitoring immediately after bariatric surgery and the need for additional psychosocial support to be available for vulnerable sub-groups of adolescents. Further studies with larger samples are necessary to identify characteristics predictive of short-term adverse psychological outcomes in adolescents after bariatric surgery.

X-Ray Diffraction from Isolated and Strongly Aligned Gas-Phase Molecules with a Free-Electron Laser

Journal article (peer-reviewed)abstract
- We report experimental results on x-ray diffraction of quantum-state-selected and strongly aligned ensembles of the prototypical asymmetric rotor molecule 2,5-diiodobenzonitrile using the Linac Coherent Light Source. The experiments demonstrate first steps toward a new approach to diffractive imaging of distinct structures of individual, isolated gas-phase molecules. We confirm several key ingredients of single molecule diffraction experiments: the abilities to detect and count individual scattered x-ray photons in single shot diffraction data, to deliver state-selected, e.g., structural-isomer-selected, ensembles of molecules to the x-ray interaction volume, and to strongly align the scattering molecules. Our approach, using ultrashort x-ray pulses, is suitable to study ultrafast dynamics of isolated molecules.
