- The purpose of this paper is to provide a synopsis of some major trends that have marked discussions on global learning for sustainable development (GLSD) in higher education. The aim is formulated against the background of the complexity represented in GLSD, as well as the fact that sustainable development (SD) is an issue of global interest for universities.Design/methodology/approachThe authors conducted an overview in recent trends in research on GLSD in higher education over the last 20 years, based on the combination of the keyword higher education for Sustainable Development with global learning (GL) and global education.FindingsThe overview suggests that only relatively limited steps have been implemented to achieve GLSD, and rhetoric still dominates the discussions. It appears that little empirical research has been undertaken on learning in global settings. Several authors have identified the need for a competence‐based curriculum for GLSD.Originality/valueUniversities, professionals and students need to take greater responsibility. How knowledge, values and abilities are formed and developed from the global learner's perspective therefore, remains an open and fundamental question. The paper underlines the crucial role that higher education plays in GL for sustainability.

Solvent segregation and capillary evaporation at a superhydrophobic surface investigated by confocal Raman microscopy and force measurements
- 2011

Journal article (peer-reviewed)abstract
- Wetting of water, a 1 : 1 water/ethanol mixture and an aqueous dodecylbenzene sulfonic acid surfactant solution on hydrophobic and superhydrophobic surfaces were studied using confocal Raman microscopy. The superhydrophobic surfaces were prepared by immersion of a glass substrate in a silica particle/fluoropolymer formulation followed by silanization. Preparation of hydrophobic surfaces was done in the same way with the exception that the silica particles were excluded from the formulation. The hydrophobic and superhydrophobic surfaces were characterized with respect to surface roughness using AFM, and by contact angle measurements using different liquids. Confocal Raman microscopy measurements in a 1 : 1 water/ethanol mixture showed an enrichment of ethanol close to the superhydrophobic surface, which could not be observed for the hydrophobic surface. Unexpectedly, the Raman spectrum of a pure water film in close proximity to the superhydrophobic surface displayed some differences compared to that of bulk water and indicated a stronger hydrogen-bonding close to the superhydrophobic surface. Evidence for capillary evaporation next to the superhydrophobic surface was also found, and this results in very long-range capillary attraction between one superhydrophobic surface and a hydrophobic colloidal probe as shown by AFM colloidal probe force measurements. Addition of a surfactant or ethanol suppresses capillary evaporation.

Journal article (peer-reviewed)abstract
- Background: Dizziness is common among patients with first time stroke. It affects self-perceived health and is a risk factor for falls. Vestibular rehabilitation (VR) is effective for treating dizziness among various conditions, but the effect of dizziness with origin in the central nervous system is poorly studied.This pilot study of a randomized controlled trial aimed at investigating a vestibular rehabilitation programme among patients with first time stroke and concomitant dizziness. A second aim was to study the feasibility of performing the randomized controlled trial.Methods: The participants were computer generated randomized to either an intervention or a control group. The intervention comprised of four different vestibular rehabilitation exercises, adapted for each patient and usual rehabilitation. The control group received usual rehabilitation without the vestibular rehabilitation exercises. Outcome measures used were The Activities-specific Balance Confidence Scale, the Berg Balance Scale, the Functional Gait Assessment Scale and the EuroQol-5D. Feasibility was studied in terms of recruitment, adherence and retention rates, also as the ability to collect primary and secondary outcomes as well as to find indications of treatment differences.Results: Self-rated health improved for all participants. No other differences between baseline and follow-up were detected neither within nor between groups. Recruitment rate was 23%, adherence to the intervention 90%, retention rate 69% and ability to collect outcome measures 90%. No adverse events occurred.Conclusion: Both the intervention and the control groups improved in self-perceived health. The measures of feasibility were satisfactory in this study, apart from a low recruitment rate.

Parkinson's Disease Case Ascertainment in the EPIC Cohort : The NeuroEPIC4PD Study
- 2015

Journal article (peer-reviewed)abstract
- Background/Aims: Large epidemiological prospective studies represent an important opportunity for investigating risk factors for rare diseases such as Parkinson's disease (PD). Here we describe the procedures we used for ascertaining PD cases in the EPIC (European Prospective Investigation into Cancer and Nutrition) study. Methods: The following three-phase procedure was used: (1) elaboration of a NeuroEPIC4PD template for clinical data collection, (2) identification of all potential PD cases via record linkage and (3) validation of the diagnosis through clinical record revision, in a population of 220,494 subjects recruited in 7 European countries. All cases were labelled with the NeuroEPIC4PD diagnoses of 'definite', 'very likely', 'probable', or 'possible' PD. Results: A total of 881 PD cases were identified, with over 2,741,780 person-years of follow-up (199 definite, 275 very likely, 146 probable, and 261 possible). Of these, 734 were incident cases. The mean age at diagnosis was 67.9 years (SD 9.2) and 458 patients (52.0%) were men. Bradykinesia was the most frequent presenting motor sign (76.5%). Tremor-dominant and akinetic rigid forms of PD were the most common types of PD. A total of 289 patients (32.8%) were dead at the time of the last follow-up. Conclusions: This exercise proved that it is feasible to ascertain PD in large population-based cohort studies and offers a potential framework to be replicated in similar studies.

Doctoral thesis (other academic/artistic)abstract
- Conditions to promote students' knowledge and education about environment The objectives of this Study are: · To describe and analyse the development of students' knowledge about the environment · To elucidate the nature of student thinking about the environment and, from the findings, to suggest the potential of Environmental Education Environmental education is multi-disciplinary and complex. The theoretical background to this Study is based on an holistic approach and interrelationships and on ideas from Charles S. Peirce, Gregory Bateson and Lennart Svensson. Thirty-two students (aged about 19 years) from upper secondary school were interviewed. All attended a class focussing on natural sciences. The subsequent analysis was interpretative, seeking to categorise different kinds of student thinking. The method adopted was contextual analysis. The Study demonstrates different ways in which students form knowledge. It shows also the difficulties students experience in achieving an holistic approach; they experience problems not only with temporal and spatial dimensions, but also with political and economic considerations. The Study focuses on "the people and resources in the environment". Resources are related to both nature and culture. The integration of Humanities and Natural Sciences, acting as a basis for Environmental Education, facilitates an holistic approach based on student thinking.

Hydrophobic pore array surfaces : Wetting and interaction forces in water/ethanol mixtures
- 2013
-
In: Journal of Colloid and Interface Science. - : Elsevier BV. - 0021-9797 .- 1095-7103. ; 396, s. 278-286

Journal article (peer-reviewed)abstract
- Interactions between and wetting behavior of structured hydrophobic surfaces using different concentrations of water/ethanol mixtures have been investigated. Silica surfaces consisting of pore arrays with different pore spacings and pore depths were made hydrophobic by silanization. Their static and dynamic contact angles were found to be independent of the pore depth while fewer pores on the surface, i.e. a closer resemblance to a flat surface, gave a lower contact angle. As expected, a higher amount of ethanol facilitated wetting on all the surfaces tested. Confocal Raman microscopy measurements proved both water and ethanol to penetrate into the pores. AFM colloidal probe force measurements clearly showed that formation of air cavitation was hindered between the hydrophobic surfaces in presence of ethanol, and an increase in ethanol concentration was followed by a smaller jump-in distance and a weaker adhesion force. On separation, an immediate jump-out of contact occurred. The measured forces were interpreted as being due to capillary condensation of ethanol between the surfaces giving rise to very unstable cavities immediately rupturing on surface separation.
