A1 - Pinhasi, Ron T1 - Genome flux and stasis in a five millennium transect of European prehistory JF - Nature Communications N2 - The Great Hungarian Plain was a crossroads of cultural transformations that have shaped European prehistory. Here we analyse a 5,000-year transect of human genomes, sampled from petrous bones giving consistently excellent endogenous DNA yields, from 13 Hungarian Neolithic, Copper, Bronze and Iron Age burials including two to high (similar to 22x) and seven to similar to 1x coverage, to investigate the impact of these on Europe's genetic landscape. These data suggest genomic shifts with the advent of the Neolithic, Bronze and Iron Ages, with interleaved periods of genome stability. The earliest Neolithic context genome shows a European hunter-gatherer genetic signature and a restricted ancestral population size, suggesting direct contact between cultures after the arrival of the first farmers into Europe. The latest, Iron Age, sample reveals an eastern genomic influence concordant with introduced Steppe burial rites. We observe transition towards lighter pigmentation and surprisingly, no Neolithic presence of lactase persistence.

T1 - Upper Palaeolithic genomes reveal deep roots of modern Eurasians JF - Nature Communications N2 - We extend the scope of European palaeogenomics by sequencing the genomes of Late Upper Palaeolithic (13,300 years old, 1.4-fold coverage) and Mesolithic (9,700 years old, 15.4-fold) males from western Georgia in the Caucasus and a Late Upper Palaeolithic (13,700 years old, 9.5-fold) male from Switzerland. While we detect Late Palaeolithic-Mesolithic genomic continuity in both regions, we find that Caucasus hunter-gatherers (CHG) belong to a distinct ancient clade that split from western hunter-gatherers similar to 45 kya, shortly after the expansion of anatomically modern humans into Europe and from the ancestors of Neolithic farmers similar to 25 kya, around the Last Glacial Maximum. CHG genomes significantly contributed to the Yamnaya steppe herders who migrated into Europe similar to 3,000 BC, supporting a formative Caucasus influence on this important Early Bronze age culture. CHG left their imprint on modern populations from the Caucasus and also central and south Asia possibly marking the arrival of Indo-Aryan languages.

We assessed colored dissolved organic matter (CDOM) absorption at 440 nm (a(440)(CDOM)) and absorption slope (S300-500) in lakes using field sampling and optical remote sensing data for an area of 350 km(2) in Central Yamal, Siberia. Applying a CDOM algorithm (ratio of green and red band reflectance) for two high spatial resolution multispectral GeoEye-1 and Worldview-2 satellite images, we were able to extrapolate the a()(CDOM) data from 18 lakes sampled in the field to 356 lakes in the study area (model R-2 = 0.79). Values of a(440)(CDOM) in 356 lakes varied from 0.48 to 8.35 m(-1) with a median of 1.43 m(-1). This a()(CDOM) dataset was used to relate lake CDOM to 17 lake and lake catchment parameters derived from optical and radar remote sensing data and from digital elevation model analysis in order to establish the parameters controlling CDOM in lakes on the Yamal Peninsula. Regression tree model and boosted regression tree analysis showed that the activity of cryogenic processes (thermocirques) in the lake shores and lake water level were the two most important controls, explaining 48.4% and 28.4% of lake CDOM, respectively (R-2 = 0.61). Activation of thermocirques led to a large input of terrestrial organic matter and sediments from catchments and thawed permafrost to lakes (n = 15, mean a(440)(CDOM) = 5.3 m(-1)). Large lakes on the floodplain with a connection to Mordy-Yakha River received more CDOM (n = 7, mean a(440)(CDOM) = 3.8 m(-1)) compared to lakes located on higher terraces.

The active agent Monensin (MON) belongs to the ionophore antibiotics and is widely used as a veterinary drug against coccidiosis in broiler farming. However, no electrochemically (EC) generated TPs of MON have been described so far. In this study, the online coupling of EC and mass spectrometry (MS) was used for the generation of oxidative TPs. EC-conditions were optimized with respect to working electrode material, solvent, modifier, and potential polarity. Subsequent LC/HRMS (liquid chromatography/high resolution mass spectrometry) and MS/MS experiments were performed to identify the structures of derived TPs by a suspected target analysis. The obtained EC-results were compared to TPs observed in metabolism tests with microsomes and hydrolysis experiments of MON. Five previously undescribed TPs of MON were identified in our EC/MS based study and one TP, which was already known from literature and found by a microsomal assay, could be confirmed. Two and three further TPs were found as products in microsomal tests and following hydrolysis, respectively. We found decarboxylation, O-demethylation and acid-catalyzed ring-opening reactions to be the major mechanisms of MON transformation.

In this study, we compared the skin penetration of tacrolimus formulated in tNGs with a commercial 0.1% tacrolimus ointment. The penetration of the drug was investigated in ex vivo abdominal and breast skin, while different methods for skin barrier disruption were investigated to improve skin permeability or simulate inflammatory conditions with compromised skin barrier. The amount of penetrated tacrolimus was measured in skin extracts by liquid chromatography tandem-mass spectrometry (LC-MS/MS), whereas the inflammatory markers IL-6 and IL-8 were detected by enzyme-linked immunosorbent assay (ELISA). Higher amounts of tacrolimus penetrated in breast as compared to abdominal skin or in barrier-disrupted as compared to intact skin, confirming that the stratum corneum is the main barrier for tacrolimus skin penetration. The anti-proliferative effect of the penetrated drug was measured in skin tissue/Jurkat cells co-cultures. Interestingly, tNGs exhibited similar anti-proliferative effects as the 0.1% tacrolimus ointment. We conclude that polyglycerol-based nanogels represent an interesting alternative to paraffin-based formulations for the treatment of inflammatory skin conditions.

Akan has two types of wh-question structures (wh-in-situ and wh-ex-situ questions), which allows an investigation of children’s acquisition of these two question structures and their preferences for one or the other. Our results show that adults prefer to use wh-ex-situ questions over wh-in-situ questions. The results from the children show that both age groups have the two question structures in their linguistic repertoire. However, they differ in their preferences in usage in the elicited production task: while the 5-year-olds preferred the wh-in-situ structure over the wh-ex-situ structure, the 4-year-olds showed a selective preference for the wh-in-situ structure in who-questions. These findings suggest a developmental change in wh-question preferences in Akan-learning children between 4 and 5 years of age with a so far unobserved u-shaped developmental pattern. In the elicited imitation task, all groups showed a strong tendency to maintain the structure of in-situ and ex-situ questions in repeating grammatical questions. When repairing ungrammatical ex-situ questions, structural changes to grammatical in-situ questions were hardly observed but the insertion of missing morphemes while keeping the ex-situ structure. Together, our findings provide only partial support for the Derivational Complexity Hypothesis.

T1 - Times Associated With Source-to-Sink Propagation of Environmental Signals During Landscape Transience JF - Frontiers in Earth Science N2 - Sediment archives in the terrestrial and marine realm are regularly analyzed to infer changes in climate, tectonic, or anthropogenic boundary conditions of the past. However, contradictory observations have been made regarding whether short period events are faithfully preserved in stratigraphic archives; for instance, in marine sediments offshore large river systems. On the one hand, short period events are hypothesized to be non-detectable in the signature of terrestrially derived sediments due to buffering during sediment transport along large river systems. On the other hand, several studies have detected signals of short period events in marine records offshore large river systems. We propose that this apparent discrepancy is related to the lack of a differentiation between different types of signals and the lack of distinction between river response times and signal propagation times. In this review, we (1) expand the definition of the term ‘signal’ and group signals in sub-categories related to hydraulic grain size characteristics, (2) clarify the different types of ‘times’ and suggest a precise and consistent terminology for future use, and (3) compile and discuss factors influencing the times of signal transfer along sediment routing systems and how those times vary with hydraulic grain size characteristics. Unraveling different types of signals and distinctive time periods related to signal propagation addresses the discrepancies mentioned above and allows a more comprehensive exploration of event preservation in stratigraphy – a prerequisite for reliable environmental reconstructions from terrestrially derived sedimentary records.

To address this deficiency, the inaugural Malaysian Chapter of the International Deans’ Course (MyIDC) was held in three parts over 2019 and 2020. In this paper, findings related to feedback on the programme are presented and discussed. Responses from the participants from two sets of surveys, and written feedback provided by two IDC international trainers involved in MyIDC were analysed. These reveal potential areas of improvement for the forthcoming MyIDC programme, such as in terms of planning and organisation, duration, content, and delivery. The article explores the lessons learnt from the MyIDC 2019/2020 training programme and discusses the improvements that can be made arising from the feedback received.

This led the authors of this article to further examine the question of PhD completion rates. Available data underlined that PhD students across various disciplines in Kenya’s public universities take unnecessarily long to complete their studies due to a myriad of factors that are related to their supervisors, university guidelines for post-graduate studies, or the students themselves.

Institutional evaluations of higher education and research institutions in 2013 could not initiate the implementation of change processes within the institutions. Recently, however, various initiatives have been started to change this situation with the purpose to sensitise and raise awareness and capabilities for quality assurance structures in Guinean HEIs. So far, the emphasis has been put on quality enhancement in higher education, especially on teaching evaluation, curriculum development, as well as on establishing quality assurance structures. This article gives an overview of the state of play and takes stock of the activities that have been initiated to set up quality assurance mechanisms in higher education and research institutions, and presents perspectives for further development of the quality approach in Guinea. The project ‘Quality Assurance Multiplication 2017-2018’ serves as an example to describe approaches and activities in setting up stable quality assurance structures, and to strengthen and raise awareness for a ‘quality culture’.

Faktoren für den Studienerfolg in der Eingangsphase und zur Studienmitte BT - Befunde und Empfehlungen des StuFo-Projekts JF - Potsdamer Beiträge zur Hochschulforschung N2 - Die hohen Abbruchquoten, insbesondere in der Studieneingangsphase, haben die Hochschulen in Deutschland veranlasst, eine Vielzahl von Maßnahmen zu ergreifen, über deren Wirkungen bisher allerdings wenig bekannt ist. Im vorliegenden Beitrag werden Befunde eines Forschungsprojekts speziell zur Studieneingangsphase sowie ergänzend zur Studienmitte vorgestellt, dessen Ziel es war, Bedingungen eines erfolgreichen Studieneinstiegs zu identifizieren und Empfehlungen für eine Optimierung des Studieneingangs abzuleiten. Das Forschungsdesign umfasste neben qualitativen Studien vor allem eine quantitative Längsschnittbefragung an fünf Universitäten (Potsdam, Mainz, Magdeburg, Kiel und Greifswald). Im Ergebnis der Analysen konnte die forschungsleitende Hypothese, dass Maßnahmen zum Studieneingang vor allem dann zur Erhöhung des Studienerfolgs einen Beitrag leisten, wenn sie zur akademischen und sozialen Integration in die Hochschule beitragen, bestätigt werden. Bedeutsam für den Studienerfolg sind demnach insbesondere solche Faktoren wie die Identifikation mit dem Studienfach, die Selbstwirksamkeit, die berufliche bzw. erfolgsorientierte Lernmotivation und die akademische Integration. Daneben konnte ein positiver Einfluss des sozialen Klimas sowie des Forschungs- und Praxisbezugs auf die Studienzufriedenheit nachgewiesen werden. Weiterführende Analysen zur Studienmitte verdeutlichen zudem, dass für die beiden Studienphasen (Eingang und Studienmitte) gleiche Faktoren bei zum Teil unterschiedlicher Gewichtung eine Rolle spielen. So ist die soziale Integration ein wesentlicher Prädiktor in beiden Phasen – in der Eingangsphase eher in die Studierendenschaft und im weiteren Studienverlauf (Studienmitte) eher in die akademische Gemeinschaft (in Form von Lehrenden). Insofern muss die Eingangsfrage wie folgt beantwortet werden: Ja, alles auf Anfang, aber dann mit den Bemühungen, soziale und akademische Integration aller Studierenden voll und ganz zu gewährleisten. Zudem machen die Befunde auf die bisher offenbar unterschätzte Rolle von Verwertungsmotiven aufmerksam.
