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

The reflection of human activity in the sediments of Iwankowskie Lake from Subatlantic Phase (Polish Outer Carpathians) 总被引:2,自引:0,他引:2

The paper presents the analysis of organic and mineral sediments filling the depression, which developed over the landslide located at the slope (767–773 m a.s.l.) of Lubań ridge decscending to the Ochotnica river valley in the Polish Flysch Carpathians. The landslide formed in an early stage of the Subatlantic Phase (2490 ± 35 BP). The top of peat is dated at 1360 ± 50 years BP and is covered by 72 cm of clayey silts with some sandy intercalations, which indicate slopewash after deforestation. The pollen of ruderal plants and Cerealia (undiff.) reflect agricultural activity in the surroundings. The fragments of charcoal indicate the age of the forest clearance to the first half of the 17th century. The late forest clearance at the elevated north exposed slopes followed 200–300 years later in relation to the foundation of the village at the valley floor. 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

Changing patterns of carnivore modification in a landscape bone assemblage, Amboseli Park, Kenya 总被引:2,自引:1,他引:1
This study compares the landscape-scale taphonomic signal of carnivore modification to the surficial bone assemblage in Amboseli Park, Kenya as it was in 1975 and 2002–2004. Change in predator abundances over time provides a means of assessing the taphonomic signal of carnivore-mediated bone consumption and destruction under differing ecological conditions and varying levels of conspecific competition for resources. The landscape assemblage indicates taxonomic variation in the patterning of carnivore modification to ungulates of different size classes as well as within equivalent size classes. Analyses of long bone elements indicate that the differential destruction of limb ends and the strength of the correlation between limb end abundance and bone mineral density provide an indication of the intensity of carnivore modification to a faunal assemblage. The ability to infer levels of carnivore modification based on limb elements can provide faunal analysts with the tools to determine whether the taphonomic signals in the fossil record relate to carnivore modification, hominin transport of appendicular elements, or both. 相似文献

ABSTRACT This article deals with how, in the urban setting of Madang, Papua New Guinea, Marian devotion is deployed in response to domestic and gender‐based violence. While providing insight into the lived religious experiences of Catholic women living in Madang, this article shows how Mary empowers her followers to resist violence, yet, at the same time, paradoxically, is instrumental in sanctioning women to tolerate violence. Josephine's ‘journey of violence’ reveals not only Josephine's turning to Mary, but more so, her negotiations with values belonging to different cultural logics. Caught between ‘tradition’, Christianity and ‘modernity’, Josephine and other Catholic women engage in painful processes of self‐analysis and self‐transformation to adapt to and change their situation. In these processes, Mary is used as a role model. 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.
