"'Armut' läßt sich heute nicht mehr auf einfache Weise verbindlich definieren. Schon auf individueller Ebene ist nicht klar, nach welchen objektiven Maßstäben als 'arm' bezeichnet werden kann, wer sich arm fühlt. Individuelle Befindlichkeit hängt immer vom gesellschaftlichen (d.h. nationalen) Umfeld ab. Da die nationale Situation wiederum und zunehmend vom internationalen System abhängt, zeigt 'Armut' ihr internationales Gesicht. Es werden einige der zu diesen Problemen diskutierten Theorien der Armut skizziert. 1. Das Beispiel ländlicher Armut in einem 'Entwicklungsland', den Philippinen. 2. Eine Beschreibung von 'neuer Armut im Reichtum': die Entdeckung von Armut in der Europäischen Gemeinschaft. Bei wachsendem Wohlstand verschwindet Armut nicht, sondern stellt sich nach wie vor als - wenngleich relatives - sozialpolitisches Problem. Die Maßnahmen zur Armutsbekämpfung der 'Ersten Welt', der EG, werden analysiert und Erfordernissen der Armutsbekämpfung in der 'Dritten Welt' gegenübergestellt. 3. Die globale Dimension der Armut wird anhand der Aktivitäten der Vereinten Nationen und ihrer Entwicklungssozialpolitik dargestellt. Im Vordergrund steht der Ansatz universaler Menschenrechte: Sie sind das stärkste Argument, um die Staatenwelt für eine Kooperation zu gewinnen, welche es auch den vielen armen Einzelstaaten der 'Dritten Welt' ermöglicht, dem Wohlbefinden des einzelnen zu dienen."

The Intcal20 Northern Hemisphere radiocarbon age calibration curve (0-55 cal kBP). Radiocarbon, 62(4), (2020): 725-757, doi:10.1017/RDC.2020.41. ; Radiocarbon (14C) ages cannot provide absolutely dated chronologies for archaeological or paleoenvironmental studies directly but must be converted to calendar age equivalents using a calibration curve compensating for fluctuations in atmospheric 14C concentration. Although calibration curves are constructed from independently dated archives, they invariably require revision as new data become available and our understanding of the Earth system improves. In this volume the international 14C calibration curves for both the Northern and Southern Hemispheres, as well as for the ocean surface layer, have been updated to include a wealth of new data and extended to 55,000 cal BP. Based on tree rings, IntCal20 now extends as a fully atmospheric record to ca. 13,900 cal BP. For the older part of the timescale, IntCal20 comprises statistically integrated evidence from floating tree-ring chronologies, lacustrine and marine sediments, speleothems, and corals. We utilized improved evaluation of the timescales and location variable 14C offsets from the atmosphere (reservoir age, dead carbon fraction) for each dataset. New statistical methods have refined the structure of the calibration curves while maintaining a robust treatment of uncertainties in the 14C ages, the calendar ages and other corrections. The inclusion of modeled marine reservoir ages derived from a three-dimensional ocean circulation model has allowed us to apply more appropriate reservoir corrections to the marine 14C data rather than the previous use of constant regional offsets from the atmosphere. Here we provide an overview of the new and revised datasets and the associated methods used for the construction of the IntCal20 curve and explore potential regional offsets for tree-ring data. We discuss the main differences with respect to the previous calibration curve, IntCal13, and some of the implications for archaeology and geosciences ranging from the recent past to the time of the extinction of the Neanderthals. ; We would like to thank the National Natural Science Foundation of China grants NSFC 41888101 and NSFC 41731174, the 111 program of China (D19002), U.S. NSF Grant 1702816, and the Malcolm H.
