Fostering entrepreneurship in an international university collaboration
[EN] The European Union is taking action on enhancing entrepreneurship in Europe and recommends appropriate entrepreneurship training in schools and higher education institutions. Due to the globalization of businesses it seems to be appropriate to realize an international perspective on entrepreneurial issues and to develop international programmes for young entrepreneurs. In this case study, we examined an international university collaboration between two universities, one in Austria and one in the United States. The programme’s goals include the establishment of an international network for students and an awareness of the students of different cultural dimensions and entrepreneurial mindsets. Our findings show how this programme enables the students to work on their professional and behavioural skills, how these students work practice-oriented under the guidelines of experts from different entrepreneurial mindsets and how they become aware of cultural differences. Besides other aspects, it seems to be advantageous for international entrepreneurship programmes to remain open and flexible during the whole process and to offer a programme that allows students to integrate participation into their regular studies. Furthermore, it seems beneficial that students can tailor the programme to meet their specific needs.Rybnicek, R.; Gutschelhofer, A.; Bergner, S.; Seidenberger, A.; Taferner, R. (2017).

Mental rotation of 2- and 3-dimensional objects: Sex differences, effects of training and changes in cortical activity
Microglia damage precedes major myelin breakdown in X‐linked adrenoleukodystrophy and metachromatic leukodystrophy
X‐linked adrenoleukodystrophy (X‐ALD) and metachromatic leukodystrophy (MLD) are two relatively common examples of hereditary demyelinating diseases caused by a dysfunction of peroxisomal or lysosomal lipid degradation. In both conditions, accumulation of nondegraded lipids leads to the destruction of cerebral white matter. Because of their high lipid content, oligodendrocytes are considered key to the pathophysiology of these leukodystrophies. However, the response to allogeneic stem cell transplantation points to the relevance of cells related to the hematopoietic lineage. In the present study, we aimed to better characterize the pathogenetic role of microglia in the above‐mentioned diseases. Applying recently established microglia markers to human autopsy cases of X‐ALD and MLD we were able to delineate distinct lesion stages in evolving demyelinating lesions. The immune‐phenotype of microglia was altered already early in lesion evolution, and microglia loss preceded full‐blown myelin degeneration both in X‐ALD and MLD. DNA fragmentation indicating phagocyte death was observed in areas showing microglia loss. The morphology and dynamics of phagocyte decay differed between the diseases and between lesion stages, hinting at distinct pathways of programmed cell death. In summary, the present study shows an early and severe damage to microglia in the pathogenesis of X‐ALD and MLD. This hints at a central pathophysiologic role of these cells in the diseases and provides evidence for an ongoing transfer of toxic substrates primarily enriched in myelinating cells to microglia

We aimed at improving the reliability and validity of MR-based locus coeruleus detection. Leveraging a meta-analytical approach, we aggregated across previously published maps of the locus coeruleus (Betts et al., 2017; Dahl et al., 2019; Keren et al., 2009; Liu et al., 2019; Tona et al., 2017; Ye et al., 2020) to derive a biologically plausible volume of interest (meta mask) that shows high agreement across investigations. We freely share the locus coeruleus meta mask with the scientific community.
