    Description: The Antarctic Circumpolar Current (ACC) plays a crucial role in global ocean circulation by fostering deep-water upwelling and formation of new water masses. On geological timescales, ACC variations are poorly constrained beyond the last glacial. Here, we reconstruct changes in ACC strength in the central Drake Passage in vicinity of the modern Polar Front over a complete glacial-interglacial cycle (i.e., the past 140,000 years), based on sediment grain-size and geochemical characteristics. We found significant glacial-interglacial changes of ACC flow speed, with weakened current strength during glacials and a stronger circulation in interglacials. Superimposed on these orbital-scale changes are high-amplitude millennialscale fluctuations, with ACC strength maxima correlating with diatom-based Antarctic winter sea-ice minima, particularly during full glacial conditions. We infer that the ACC is closely linked to Southern Hemisphere millennial-scale climate oscillations, amplified through Antarctic sea ice extent changes. These strong ACC variations modulated Pacific-Atlantic water exchange via the “cold water route” and potentially affected the Atlantic Meridional Overturning Circulation and marine carbon storage.

    Description: Marine sedimentary records are a key archive when reconstructing past climate; however, mixing at the seabed (bioturbation) can strongly influence climate records, especially when sedimentation rates are low. By commingling the climate signal from different time periods, bioturbation both smooths climate records, by damping fast climate variations, and creates noise when measurements are made on samples containing small numbers of individual proxy carriers, such as foraminifera. Bioturbation also influences radiocarbon-based age-depth models, as sample ages may not represent the true ages of the sediment layers from which they were picked. While these effects were first described several decades ago, the advent of ultra-small-sample $^{14}$C dating now allows samples containing very small numbers of foraminifera to be measured, thus enabling us to directly measure the age-heterogeneity of sediment for the first time. Here, we use radiocarbon dates measured on replicated samples of 3-30 foraminifera to estimate age-heterogeneity for five marine sediment cores with sedimentation rates ranging from 2-30 cm kyr$^{-1}$. From their age-heterogeneities and sedimentation rates we infer mixing depths of 10-20 cm for our core sites. Our results show that when accounting for age-heterogeneity, the true error of radiocarbon dating can be several times larger than the reported measurement. We present estimates of this uncertainty as a function of sedimentation rate and the number of individuals per radiocarbon date. A better understanding of this uncertainty will help us to optimise radiocarbon measurements, construct age models with appropriate uncertainties and better interpret marine paleo records.

    Description: The aim of this paper is to investigate, through fnancial-statement analyzes, the economic fnancial performance of Italian hotels, after the international economic crisis, also con sidering the possible macro-regional diferences. The study focuses the fnancial state ments of 5473 hotels from 2009 to 2018. National data are also disaggregated in the three macro-areas that characterize Italy for diferent social and economic aspects. Anova test and Tukey–Kramer test are used. Results show that the crisis afected proftability. Ital ian hotels have a low capitalization, unable to cope with the large structural investments that require signifcant debts. The proftability indicators record similar trends in the three macro-areas, while the fnancial independence index and the coverage index show signif cant diferent values in the three observed areas. Therefore, in the digital era, Italian hotel industry has all the potential to restructure itself. Here fve ratios are considered to observe medium sized hotels. Future research with other variables will be useful, even on smaller hotels, and the analysis of their trends by cohorts of companies is necessary, as well as the integration of quantitative data with qualitative evidence. This paper encourages the cul ture of temporal sector comparison, re-evaluating the potential of accounting information systems, in order to promote data-based growth and development strategies. Furthermore, it contains indications for government ofcials, as well as for countries in the process of developing the hospitality sector following the example of the Italian experience.

    Description: Die Landwirtschaft in Deutschland, Europa und weltweit befindet sich in einem dramatischen Umbruchprozess. Einerseits bieten Liberalisierung und Marktöffnung, neue technologische Entwicklungen, die wachsende Weltbevölkerung und neue Kundenwünsche vielen landwirtschaftlichen Betrieben neue Möglichkeiten. Andererseits stehen viele Landwirtinnen und Landwirte in internationaler Konkurrenz, sind zum betrieblichen Wachstum mit hohem Investitionsrisiko gezwungen, sind Teil strikt regulierter Wertschöpfungsketten und müssen steigenden gesellschaftlichen Ansprüchen genügen. Zugleich machen sich viele Menschen Sorgen, dass die Prozesse der Rationalisierung und Modernisierung der landwirtschaftlichen Produktion auf Kosten von Natur-, Umwelt- und Tierschutz gehen. Auf vielen Ebenen wird daher bereits nach einer neuen Verständigung darüber gesucht, was die Gesellschaft von der Landwirtschaft erwartet, und welche Unterstützung die Landwirtinnen und Landwirte im Gegenzug dafür erwarten dürfen. Vor diesem Hintergrund entwickelt das vorliegende Open Access-Buch eine wissenschaftlich fundierte Kritik der Umweltauswirkungen der Landwirtschaft und der politischen Logik der Agrarpolitik. Es präsentiert ein neues Leitbild mit konkreten Indikatoren sowie alternative strategische Handlungsoptionen. Die umfassende Analyse wird zu einem Vorschlag für eine neue Architektur der europäischen Agrarpolitik gebündelt, die eine breite Diskussion um einen Neuen Gesellschaftsvertrag für die Landwirtschaft in Deutschland und Europa anstoßen soll.

    Description: Dieses Open-Access-Buch erläutert ein Handlungsmodell zur Gestaltung sozialer Versorgung. Das Modell beinhaltet 16 Gestaltungsaufgaben, die sich an den wesentlichen Planungs- und Steuerungsaufgaben sozialer Versorgung und den vier Phasen eines Managementkreislaufes (Analyse, Strategieentwicklung, Umsetzung, Weiterentwicklung) orientieren. Dem Handlungsmodell liegt ein prozessorientiertes, reflexives und an der Sozialen Arbeit ausgerichtetes Handlungsverständnis zugrunde, das über „lineare“ Planungsansätze hinausreicht. Das Lehrbuch möchte Impulse für eine systematische und zugleich innovative Gestaltung sozialer Versorgung geben.

    Description: Economists have long sought to maximise economic growth, believing this to be their best contribution to improving human welfare. That approach is not sustainable in the face of ongoing issues such as global climate change, environmental damage, rising inequality and enduring poverty. Alternatives must be found. This open access book addresses that challenge. It sets out a wellbeing economics framework that directly addresses fundamental issues affecting wellbeing outcomes. Drawing inspiration from the capabilities approach of Nobel Prize winner Amartya Sen, the book demonstrates how persons can enhance prosperity through their own actions and through collaboration with others. The book examines national public policy, but its analysis also focuses on choices made by individuals, households, families, civil society, local government and the global community. It therefore offers important insights for anyone concerned with improving personal wellbeing and community prosperity.
