The Rabat-Témara region of the Moroccan Atlantic coast reveals a succession of Quaternary palaeobeaches. This coastal area is dotted with numerous prehistoric caves. The study of the Upper Pleistocene coastal landscape associated with these caves is of paramount importance in the knowledge of human population subsistence. During the Upper Pleistocene, the ocean level changes drastically influenced the coastal geomorphology as well as the fauna assemblages. The chrono-lithostratographical analysis of the coastal sedimentary formations allows the distinction of three sequences rich in marine fauna. These sequences date from MIS 11 to MIS 5. The identification of malacofauna species from these deposits revealed 39 species, along with Bryozoans, Crustaceans, and Echinoids. These assemblages show a constant fauna cortege highlighted by the dominance of the amphi-Atlantic species Stramonita haemastoma. This species shows an increase in the number of specimens in the uppermost part of marine deposits, probably in relation with a climate warming in the MIS 5. This fauna of both intertidal rocky substrates and sandy substratum indicates environmental conditions close to the present-day Rabat-Témara coastline. As in other coastal locations of Africa from MIS 5, the Middle Stone Age Homo sapiens population benefitted from a littoral environment rich in coastal resources. Comparison between thanatocenoses and archaeological records allows us to identify both species available for Middle Stone Age population and those preferred for human use.  相似文献

This paper analyses the environmental measures co-financed by the European Union (EU) Structural Funds in the less-developed regions. Specifically, it studies if these environmental measures are tailored to the specific needs of the different regions and whether they are driven by an ecological modernization approach. The inclusion of environmental goals into the regional policy is also tested by analysing its connection with the main European environmental directives. We find a suitability of the regional programmes to the regional specific environmental factors, a scarce presence of the ecological modernization paradigm behind the programmes implementation and a clear orientation of the regional programmes to meet the EU legislation.  相似文献

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest.  相似文献

The DFG, short for ‘Deutsche Forschungsgemeinschaft’ (German Research Foundation), was founded in 1920 and re‐founded after the 2. World War in 1949. This article concentrates on the activities of the DFG in the period between 1949 and the end of the sixties and on the two major programmes (the so‐called ‘Individual Grants Programme’ and the so‐called ‘Priority Programme’) because until now it has not been known, how many — and more importantly — which studies in which disciplines had been financed by the DFG. All together almost 54.000 studies (36.500 in the ‘Individual Grants Programme’ and 17.400 in the ‘Priority Programmes’) were accomplished with the support of the DFG, whereas — in the ‘Individual Grants Programme’ — less than 3.000 proposals were declined (there are no figures for the ‘Priority Programmes’). Till the end of the seventies the whole amount of money allocated for the ‘Individual Grants Programme’ was not fixed for the different disciplines in advance. Consequently every proposal submitted in the ‘Individual Grants Programme’ had to compete against all others for the overall allocated funds. Who — in other words: which of the disciplines — won this competition? The analysis shows a clear result. With regard to both, the number of successful proposals and the money received, the winner was medical science (with 23 percent of all successful proposals in the ‘Individual Grants Programme’). Chemistry finished second with 15 percent and then biology a distant third (9 percent), followed by physics (8 percent) and agronomy (8 percent). Coming to the ‘Priority Programmes’, which were instituted in the middle of the 1950s, it must first be stated that here the topic is fixed in advance. The broad issue of investigation is devised by the DFG itself or — to be more precise — by the Senate of the DFG. In contrast to the ‘Individual Grants Programme’ the ‘Priority Programme’ can therefore be seen as an important instrument of the politics of research support. This leads to the following question: Which programmes did the DFG establish between 1954 and 1969? In other words: Which research topics or fields were, in the view of the DFG, the most important ones? The database again shows a clear result. Almost 50 percent of the money distributed overall and more than 50 percent of all programmes were benefitted to natural science, another fifth part to engineering technology (which didn't play an important role in the ‘Individual Grants Programme’). Medical science which was the most successful discipline in the ‘Individual Grants Programme’ received 16 percent of the funds. With regard to — first — the number of successful proposals within a Programme, — second — to the money received and — third — to the duration there were three frontrunner programmes: nourishment research, research on water and hydraulic engineering, and aeronautical research. And the humanities? The DFG didn't grant much relief giving only 7 percent to these disciplines.  相似文献

In the 1970s and 1980s, regional analysis was an influential part of archaeological research, providing a discrete set of geographical tools inspired by a processual epistemological and interpretive perspective. With the advent of new technologies, new methods, and new paradigms, archaeological research on regional space has undergone significant changes. This article reviews the state of regional archaeology, beginning with a consideration of its history and a discussion of the fundamental issues facing regional investigations before focusing on developments over the last several years. On one hand, the diversification of archaeological theory has created new paradigms for thinking about human relationships with one another and with the physical environment across regional space; in this regard, historical ecology, landscape archaeology, and evolutionary theory have been particularly influential in recent years. This has led to a corresponding diversification of the traditional methods of regional analysis. Most notably, the advent of powerful digital technologies has introduced new tools, especially those from the geographic information sciences, that build on the quantitative methods of past approaches. The investigation of regional data is no longer based on a discrete toolkit of simple mathematical and graphical procedures for representing spatial relationships. Instead, regional archaeology has matured into a diversity of multiscalar spatial and geostatistical techniques that inform many areas of archaeological inquiry.  相似文献

This article focuses on the presence of humans in Siberia and the Russian Far East at the coldest time of the Late Pleistocene, called the Last Glacial Maximum (LGM) and dated to c. 20,000–18,000 rcbp. Reconstruction of the LGM environment of Siberia, based on the latest models and compilations, provides a background for human existence in this region. Most of Siberia and the Russian Far East at c. 20,000–18,000 rcbp was covered by tundra and cool steppe, with some forest formations in the river valleys. Climate was much colder and drier than it is today. Eighteen Upper Paleolithic sites in Siberia are radiocarbon dated strictly to the LGM, and at least six of them, located in southern parts of western and eastern Siberia and the Russian Far East, have solid evidence of occupation during that time span. It seems clear that southern Siberia was populated by humans even at the height of the LGM, and that there was no dramatic decline or complete disappearance of humans in Siberia at that time. The degree of human adaptation to periglacial landscapes in the mid-Upper Paleolithic of northern Eurasia was quite high; humans coped with the cold and dry environmental conditions using microblade technology, artificial shelters, tailored clothes, and megafaunal bones as fuel.

During the Late Intermediate period (LIP, c. A.D. 1000–1400), the central Andes experienced the decline of the Wari and Tiwanaku states, as well as processes of state formation, regional population growth, and competition culminating in the imperial expansion of the Chimú and Inka polities. The LIP holds the potential to link the archaeological features of early Andean states with the material signatures of the later ones, providing a critical means of contextualizing the intergenerational continuities and breaks in state structures and imperial strategies. The recent proliferation of LIP research and the completion of a number of regional studies permit the overview of six LIP regions and the comparison of highland and lowland patterns of political and economic organization, social complexity, and group identity.  相似文献

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献
