Veränderung der Bodenunruhe 2020 in Wien durch Covid- 19-Maßnahmen
No full textDie Maßnahmen, die zur Eindämmung von Corona gesetzt wurden, spiegeln sich auch in derBodenunruhe in ganz Österreich wieder. Die seismologischen Messstationen desErdbebendienstes der ZAMG zeigen: der Boden vibriert deutlich weniger, wie sonst nur anWochenenden, Feiertragen und Ferienzeiten. So können u.a. kleinere Erdbeben detektiertwerden, welche eine wichtige Grundlage für Bestimmung der Erdbebengefährdung undsomit erdbebengerechtes Bauen sind.Nicht nur Erdbeben können so besser detektiert werden, die Messdaten aus diesemZeitraum bieten eine besonders gute Möglichkeit sich mit anthropogenen Quellenauseinander zu setzen: sie können leichter identifiziert und in ihrer Stärke quantifiziertwerden. Dazu analysieren wir die Daten der Messstationen der ZAMG in und nahe Wiens mitder Open-Source Software „SeismoRMS“. Anschließend präsentieren wir die Ergebnisse fürden Frequenzbereich von 4 -14 Hz mit in der Seismologie standardmäßig verwendetenDarstellungen für Bodenunruhe. Diese Darstellungen ermöglichen bei der Analyse vonBodenschwingungen wichtige Erkenntnisse über zeitliche Muster von unterschiedlichenQuellen wie Verkehr, Industrie, sowie Wetterereignissen. Abschließend präsentieren wir denAblauf der Signalanalyse eines davor unidentifizierten Messsignals, welches in Wien im Juli2020 auf allen Stationen messbar war – und natürlichen Ursprungs war
Roca and its Aegean Contacts in the Recent Bronze Age. Orea|Punta di Zambrone I Oriental and European Archaeology Volume 17|
No full textThe archaeological exploration of the peninsula of Roca (Lecce), carried out by the University of Salento, has brought to light one of the most important prehistoric settlements in the central Mediterranean. During recent years, an important stratigraphic sequence was explored in the northwest sector of the settlement (Area IX), near the internal front of the protohistoric fortification walls, and this had seven distinct occupation phases from the beginning of Recent Bronze Age 2 to Final Bronze Age 2. A large quantity of Aegean-type ceramics, both imported and locally made, were found in the Recent Bonze Age levels; moreover, the presence of many faunal remains led us to hypothesise celebrations of sacrifices and ritual meals. Various archaeological data converge to suggest that in this period Roca became an important node in a large-scale Mediterranean trade network and acquired the character of a community colony, with a significant group of Aegean immigrants

Two perspectives – one goal: resilience research in protected mountain regions. eco.mont (Journal on Protected Mountain Areas Research and Management)|eco.mont Vol. 13 No. 2 13 2|
No full textResilience at various levels of the social and environmental domains is a key aspect of sustainable development in mountain areas. However, resilience research is hampered by inconsistent definitions and conceptualizations of resilience. Using the examples of two research projects from protected mountain areas in different regions of the world (in the Austrian Alps and the Nepalese Himalayas), we illustrate two distinct perspectives on resilience: a system-based perspective and an agency-based one. We identify common characteristics of these views on resilience and apparent contradictions between them, and discuss how the two perspectives can be integrated to enhance understanding of resilience and to support sustainable development
Ad utriusque imperii unitatem? Anastasius Bibliothecarius as a Broker between Two Cultures and Three Courts in the Ninth Century. Medieval Worlds|Movement and Mobility & Ideologies of Translation, III - Volume 13. 2021 medieval worlds Volume 13. 2021|
No full textIn 870, Anastasius, former (and later once again) librarian of the papal bibliotheca and chancellery, well-known erudite and former anti-pope, reached the pinnacle of his career as a diplomat. While exiled from Rome for a crime committed by his cousin, he was an important member of a mission sent to Constantinople by the Carolingian emperor and lord of Italy Louis II. He was sent there to negotiate a marriage alliance between Louis’s daughter and only surviving child Ermengard and a son of the upstart Byzantine emperor Basil I, which was ultimately to serve to bind the two empires together in the fight against the Saracens, southern Italy and Sicily. While there, Anastasius also joined the papal delegation at the Eighth Ecumenical Council, which was there in the pope’s stead to formally depose Patriarch Photius and negotiate the case of Bulgaria. We thus see Anastasius as a diplomat and cultural broker between Latin and Greek ecclesiastic and lay culture and between three courts. He composed a letter about his dealings in the East for Pope Hadrian II in 870, and thus we have an invaluable first-hand eyewitness account. While most negotiations started in 869 and 870 between the East and the West ultimately failed or were rendered pointless by political change, Anastasius shows us that 870 was a great chance for all sides. And while most parties involved lost something by the failure of the exchanges, Anastasius himself regained and kept a powerful position in the papal administration once again

No full textJust Another level? Comparing Quantitative Patterns of Global School and Higher Education Expansion
No full textThe expansion of enrolment and attainment is a key theme in higher education research. Inparticular, research has examined cross-national determinants of higher education expansionwhile understanding expansion through the relationship between higher education and thelabour market. Early work on higher education expansion established a key framework forclassifying enrolment levels, but empirical studies on the global expansion of higher educationare scarce. This study addresses this gap by comparing the existing patterns of highereducation expansion to those experienced at other levels on the course to universal or nearuniversalaccess. We demonstrate that a model fitting universal access trajectories fits highereducation as well as other levels of education, and, therefore, there is no prima facie reason tobelieve that its expansion will face ceilings or saturation levels based upon available evidence.Claims that are premised on such a ceiling should therefore consider empirical evidence forthis assumption in their analysis. These findings contribute to discussions on higher educationexpansion as well as studies of higher education and the labour market
Spatially Supervised Text Mining for Social Media Cleaning and Preprocessing. GI_Forum|GI_Forum 2021, Volume 1|
No full textIn this paper, we show a framework for partial bot rejection based on spatially supervised text mining from social media messages. We show qualitative results towards the reduction of known bots and give hints on how this cleaning technique can help us in filling gaps of current signals related to human life on Earth based on social media. The bot rejection framework is based on using a spatial signal for supervising a machine learning model with extreme label noise still being able to reject some of the unwanted components of the social media stream. Furthermore, we comment that such models show significant biases and can, therefore, not be used responsibly without bias analysis and mitigation per application
Generalised Poisson Distributions for Modelling Parity
No full textConventional parametric count distributions, namely the Poisson and Negative-Binomialmodels, do not offer satisfactory descriptions of empirical distributions of completed cohortparity. One reason is that they cannot model variance-to-mean ratios below unity, that is,underdispersion, which is typical of low-fertility parity distributions. Statisticians haverelatively recently revived two generalised count distributions that can model bothoverdispersion and underdispersion, but that have to date not attracted the attention ofdemographers. The objective of this note is to assess the utility of these distributions, theConway-Maxwell-Poisson and Gamma Count models, for the modelling of paritydistributions, using both simulations and maximum-likelihood fitting to empirical data fromthe Human Fertility Database (HFD). The results show that these generalised countdistributions offer a greatly improved fit compared to customary Poisson and Negative-Binomial models in the presence of underdispersion, without loss of performance in thepresence of equi- or overdispersion
