Only since the turn of the 21st century have humanitarian organisations developed specific strategies that address climate change impacts as a humanitarian challenge. Taking the International Red Cross / Red Crescent Movement, being the largest humanitarian network, as an empirical case study, the article discusses the Movement’s changes in the areas 1) agenda setting, 2) organisational restructuring, 3) networking, 4) programming, and 5) advocacy. Based on the case study and a theoretical framework of organisational sociology, the article provides conclusions on internal and external factors that can explain why the Movement has been successful in being one of the first actors within the organisational field of humanitarian organisations to focus systematically on the humanitarian implications of climatic changes.

Mesenchymal stem cells (MSCs) are an attractive cell source for Regenerative Dentistry in particular due to their ability to differentiate towards osteoblasts, among other lineages. Tooth and jaw bone loss are frequent sequelae of traumatic and pathological conditions in both the young and the elderly and must be met by appropriate prosthetic replacements. For successful osseointegration of the dental implant a sufficient bone level is necessary. Besides the utilization of bone autografts or synthetic biomaterials, medical research is more and more focused on the utilization of MSCs. Compared to cells obtained from liposuction material, ectomesenchymal stem cells derived from the head area e.g. out of dental follicles or particulate, non-vascularized bone chips show a higher differentiation potential towards osteoblasts.
The aim of our research is finding measures to preserve the learners’ initial motivation in educational settings. For that we need to avoid conflicting situations that possibly could jeopardize their joy of learning.
In our thematically comprehensive Learning Culture Survey, we investigate the cultural biasing of students’ attitudes, behaviours, and expectations towards education. Particularly in times of massive international migration and growing numbers of refugees, the relevance to deeply understand cultural aspects in education increases. Just with this understanding, we can raise the awareness towards more cultural tolerance across all involved stakeholder groups and thus, foster the development of more culture-sensitive educational approaches. In this paper we focus on the most relevant aspect of motivation and comparatively discuss our study conducted in Germany and South Korea.
Mit unserer Forschung wollen wir Maßnahmen finden, die dazu beitragen, die anfängliche
Bildungsmaßnahmen zu
Motivation von Lernern bewahren. Zu diesem Zweck
in müssen Konfliktsituationen möglichst vermieden werden, wenn sie das Potential haben, ihnen die Freude am Lernen zu verderben. In unserem thematisch breitgefächerten Learning Culture Survey (Untersuchung von Lernkultur), untersuchen wir bei Lernern das Vorhandensein und den Einfluss kulturspezifischer Prägungen auf deren Verhaltensweisen, Gewohnheiten und Erwartungen bzgl. Bildung. Besonders in Zeiten massiver internationaler Migration und steigender Zahlen von Flüchtlingen wächst der Bedarf nach entsprechender Forschung stetig an. Nur wenn wir die Zusammenhänge zwischen Lernen und Kultur ausreichend verstehen, sind wir in der Lage, auf allen Ebenen die Entwicklung des erforderlichen Bewusstseins bzgl. kultursensibler Bildungsansätze zu fördern. In diesem Beitrag konzentrieren wir uns auf den sehr wichtigen Aspekt Motivation und diskutieren die Ergebnisse, die wir in unserer vergleichenden Studie in Deutschland und Südkorea erzielt haben.

The human MPV17-related mitochondrial DNA depletion syndrome is an inherited autosomal recessive disease caused by mutations in the inner mitochondrial membrane protein MPV17. Although more than 30 MPV17 gene mutations were shown to be associated with mitochondrial DNA depletion syndrome, the function of MPV17 is still unknown. Mice deficient in Mpv17 show signs of premature aging. In the present study, we used electrophysiological measurements with recombinant MPV17 to reveal that this protein forms a non-selective channel with a pore diameter of 1.8 nm and located the channel's selectivity filter. The channel was weakly cation-selective and showed several subconductance states. Voltage-dependent gating of the channel was regulated by redox conditions and pH and was affected also in mutants mimicking a phosphorylated state. Likewise, the mitochondrial membrane potential (Δψm) and the cellular production of reactive oxygen species were higher in embryonic fibroblasts from Mpv17−/− mice. However, despite the elevated Δψm, the Mpv17-deficient mitochondria showed signs of accelerated fission. Together, these observations uncover the role of MPV17 as a Δψm-modulating channel that apparently contributes to mitochondrial homeostasis under different conditions.
