In Germany and the Netherlands spatial information about the social structure of the inhabitants is used for the coordination of financial and human resources in the local school-system. The aim is to reduce educational inequalities by taking the social context of the schools into account. The article explains two approaches. In North Rhine-Westphalia (Germany) a so called Sozialindex is used to distribute additional teachers to municipalities with difficult social surroundings. The Dutch government uses an instrument to give each pupil a weight (gewichtenregeling) depending on the specific educational background. Combined with an evaluation of the school location an additional budget, if necessary, will be payed.  相似文献

The development of identification criteria for crop plants based on phytoliths is of high relevance for archaeology, palaeoecology and plant systematics. While identification criteria are available for major food crops, these are mostly based on phytoliths from inflorescences, while other plant parts remain undetected. This paper focuses on bilobate phytoliths from leaves of Panicum miliaceum L. (common millet) and Setaria italica (L.) P. Beauv. (foxtail millet), two taxa that co-occur in regions of Asia and Europe since prehistory and regularly occur at archaeological sites in Eurasia. Leaves of the investigated taxa were systematically sampled to explore the variation of short cells and to collect 27 morphometric variables of bilobate phytoliths with newly developed open-source software. The data was analysed by discriminant analysis, analysis of variance and multiple comparison tests. The resulting morphometric data from five populations per species enables a distinction between the bilobate phytoliths of P. miliaceum and S. italica. Observed differences between populations within species affect only few parameters. This possibility to classify populations of bilobate phytoliths from P. miliaceum and S. italica leaves offers a new method for the detection and identification of these taxa in archaeology, amongst others.  相似文献

The oppressors...react almost instinctively to any experiment in education which stimulates the critical faculties and is not content with a partial view of reality but which always seeks out the ties which link one point to another and one problem to another. (Freire, 1970 [1968]:60)  相似文献

In the field of maritime archaeology, the use of maritime, coastal, riverine, and lacustrine spaces by past societies has been perceived in different and changing viewpoints. These perspectives have flourished in dynamic and varying ways in many countries, and under different theoretical constructs. If in the 1970s the subject was perhaps not recognized as a central research subject by much of our community, it is now not only accepted but it has become a robust area of interest in maritime research. Two concepts in Latin America have been accepted that have had widespread application and influence, namely the regional maritime context and the maritorio. The points of contact between both are so intense that it is possible to speak about a single alternative with two possible names. In this article, their origins, applications, and theoretical influences are presented in a way that unifies these two concepts into a single approach (the maritorium), and examines how these ideas have been applied to research carried out in Mexico, Chile, and Uruguay. These applications are wide ranging, as they include the interconnected complexity between land and sea as used and inhabited by past societies. They have been applied in the study of ship traps, whole fleets, sites of maritime conflict and warfare, exploration activities, and ethnographic research. These will also be presented in light of other concepts of similar interest in the international sphere, such as the widespread concept of the Maritime Cultural Landscape, and also in view of other theoretical frameworks coming from the wider sphere of the profession, such as Landscape Archaeology and Phenomenological Archaeology.  相似文献

In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep-water (829 m) wreck of the ex-USS Independence (CVL22) using the remotely operated vehicles Argus and Hercules. The survey provided 34 h of direct observation with video and still camera documentation of the wreck, which the previous year had been initially identified with a limited three-dimensional sonar survey of the site. The 2016 assessment added considerably to an understanding of changes to Independence after its use as a target vessel for the 1946 atomic bomb tests at Bikini Atoll, as a radiological laboratory, training facility, and finally as a receptacle for “nuclear waste” prior to its scuttling off California in January 1951. The location and detailed examination of the wreck, along with additional archival research, offers a more nuanced definition of the carrier’s role within the context of the Cold War between the USSR, its adversaries and the race to establish nuclear supremacy, as well as site formation processes and ongoing biological colonization of the wreck site. As well, no evidence of residual radiological contamination was noted during the mission.  相似文献

The Boeing Company, collaborating with NOAA to address innovative ways to make ocean observations, provided their autonomous underwater vehicle, Echo Ranger, to conduct the first deep-water archaeological survey of the scuttled aircraft carrier USS Independence in the waters of Monterey Bay National Marine Sanctuary in March 2015. While a preliminary effort, and not comprehensive, the survey confirmed that a sonar feature (previously not proven to be an archaeological feature) charted at the location was Independence, and provided details on the condition of the wreck. At the same time, new information from declassified government reports provided more detail on Independence’s use as a naval test craft for radiological decontamination as well as its use as a repository for radioactive materials at the time of its scuttling in 1951. The wreck is historically significant, but also of archaeological significance as an artifact of the early years of the atomic age and of the Cold War. This article summarizes Independence’s contexts, its nuclear history, and the results of the survey of the wreck site.  相似文献

Archaebotanical evidence for Panicum miliaceum is reviewed for prehistoric Greece including published and unpublished recent finds, providing a basis for exploring the context of the appearance of millet in Greece, the timing of its introduction and cultivation, and its significance in terms of contacts, movement of people, and cultural identity as expressed through culinary practice and food consumption. To this end, the archaeobotanical record is examined together with human isotopic, archaeozoological, and artefactual evidence. Millet is introduced to the northern part of Greece sometime during the end of the 3rd millennium bc and established as a widely used crop during the Late Bronze Age. Isotopic evidence suggests that millet consumption during the Late Bronze Age was not widespread but confined to certain regions, settlements, or individuals. Millet is suggested to reach Greece from the north after its spread westwards from China through Central Asia and the steppes of Eurasia. The timing of the introduction of millet and the horse in northern Greece coincide; the possibility therefore that they are both introduced through contacts with horse breeding cultures cultivating millet in the north and/or northeast is raised. Intensified contact networks during the Bronze Age, linking prehistoric northern Greece to central Europe and the Pontic Steppes, would have opened the way to the introduction of millet, overland via river valleys leading to the Danube, or via maritime routes, linking the Black Sea to the north Aegean. Alternatively, millet could have been introduced by millet-consuming populations, moving southwards from the Eurasian steppes.  相似文献

Most Chinese archaeologists assume that the scapular implements used in the Hemudu culture in eastern China (7000–5000 BP) were the si agricultural implements (tools for breaking ground and turning soils over to assist in seeding) recorded in ancient Chinese literatures and, accordingly, assume the Hemudu culture was a farming society. However, ethnographic and historical literatures worldwide have suggested inconclusive functions for similar implements. We conducted a range of experiments under realistic conditions, including hide and plant processing and earth-working, followed by use-wear analysis, to identify the functions of the Hemudu scapular implements. The results suggest that no more than half of the implements were employed as si and that their penetrability and durability were rather limited. These findings help explain why Hemudu should not be labeled as a farming society. Through experimentation and use-wear analysis, we produced relatively large datasets that make a significant contribution to the identification of soil-derived wear patterns on bone tools. We also included quantitative measurements of soil properties to ensure similarities in use contexts between our experimental and archaeological analogies in order to reach reliable functional identifications. Our approaches and results, therefore, provided a solid base for re-evaluating previous research as well as building a standardized database of scientific value for future evaluation and adjustment, even if that future research is done in isolation and in different soil contexts.  相似文献

Meter length iron-rich rusticles on the RMS Titanic contain bacteria that reportedly mobilize iron from the ship structure at a rate that will reduce the wreck to rust in decades. Other sunken ships, such as the World War II shipwrecks in the Gulf of Mexico (GOM) are also similarly covered. However, at the GOM sites, rusticles are only centimeters in length. Minimal differences in water temperature (a few °C) between the two sites and comparable exposure times from wreckage to discovery cannot rationalize the extreme differences in rusticle length. One possible explanation for the observed difference in rusticle size is the differing amounts of dissolved or colloidal iron at the two locations.  相似文献

In August 2017, a multidisciplinary team conducted the first archaeological survey of the deep water (242 m) wreck of the ex-USS Bugara (SS/AGSS331) using the remotely operated vehicles Argus and Hercules. The survey provided 8 h of direct observation with video and still camera documentation of the wreck, which previously had been identified by sonar and a brief ROV survey of portions of the hull in 2001. The 2017 assessment added considerably to an understanding of changes to Bugara after it sank while under tow in 1971. Bugara, a World War II-era submarine, served at the end of that conflict and through the Cold War. The submarine reflects a series of modifications to “modernize” it within the context of the Cold War. The examination of the wreck, along with additional archival research, offers more details not only on the probable cause of the sinking but also on subsequent site formation processes. The characterization of the wreck resulted in a reassessment of the site as more than an obsolete vessel accidentally lost when relegated to target practice. The archival record, now declassified, shows that Bugara’s loss also reflects its ultimate use, within the context of the Cold War, as a target for the Mark 48 torpedo, a newly developed “sub and ship killing” weapon designed in the late 1960s and tested through 1971 to take out Soviet deep-diving nuclear submarines and high-performance surface ships.  相似文献

Sans résumé juin 2003 ?Mon travail a toujours cherché à concilier vérité et beauté, mais lorsque j'avais à choisir entre l'une et l'autre, généralement je préférais la beauté.? HermannWeyl Docteur en histoire de la philosophie, Dipartimento di filologia classica e di scienze filosofiche de l'université de Lecce (Italie), mes recherches portent principalement sur la philosophie de la mathématique et de la physique et sur la pensée d'Hermann Weyl. Le présent travail constitue une synthèse de mon doctorat de recherche intituléL'Unité physico-mathématique dans la pensée épistémologique d'Hermann Weyl. Ce mémoire fut achevé en juin 2003. Je me dois de remercier Charles Alunni qui, à cette occasion, comme pour cet article, m'a beaucoup aidé par sa discussion de la plupart des thèses présentées; ses très nombreuses suggestions se sont avérées extrêmement précieuses. Je saisis l'occasion pour remercier également Mario Castellana qui m'a soutenu dans ce travail, non seulement par sa grande compétence, mais en faisant preuve de beaucoup de patience; c'est à lui que je dois ce travail et c'est à lui que je le dédie. Imprécisions, erreurs ou imperfections ne sauraient relever que de ma seule responsabilité.  相似文献

Settled communities worldwide are shaped by the conceptual metaphor, social distance is physical distance. People build their houses so they are near those they are close to socially—which is usually their immediate kin—unless confounded by other factors. This metaphor is, at core, a neural connection, linking neural networks underlying the concept of distance with social categories. This connection forms in the brains of young children, under conditions found in all human societies, and should therefore operate universally. This article suggests how this metaphor can be used to reconstruct immediate social connections from the layouts of small settlements. It illustrates this by predicting the social structure of Kireyka (Darfur) from archaeologically visible materials, then compares these predictions with reported genealogies. Over three quarters of predicted social clusters are wholly or largely correct, despite competition from other concepts, as well as constraints of space, architecture, and topography. Other case studies suggest that there is no upper limit to the size of communities which may be structured by this metaphor, and that social relations may organise communities for generations.  相似文献

A relevant subject of study in the sphere of ancient Egyptian painting technology is given by the evolution of the palette across New Kingdom, Ptolemaic and Roman periods. Functionally to secondary factors such as geographic occurrence of minerals and type of associated surface, the employment of certain painting materials provides relevant insights into particular issues such as relative dating of the object and social rank of the owner. The Book of the Dead of Amenemhet (ROM 978 × 43.1, middle Ptolemaic Period) has been analysed at the Department of Restoration and Conservation of Archivals, Graphics and Book Illumination of the Cologne Institute of Conservation Sciences (Germany). Together with visible reflectance spectroscopy, digital and optical microscopy, devices such as XRD, SEM-EDX and FT-IR have been successfully employed for the characterization of the pigments from the polychrome funerary papyrus displayed at the Royal Ontario Museum, Toronto (Canada). The present research took place within a series of investigations performed at the CICS, devoted to the interdisciplinary study of funerary Egyptian papyri dating from the early 18th Dynasty onwards.  相似文献

In this paper, we report the results of an analysis of a preserved structure of jute on a ceramic artifact from the site of Harappa that is dated to 2200–1900 (cal.) BC (Fig. 1). Jute cloth has not previously been identified at this early date in the Indus civilization. Since fiber remains are rare in prehistoric South Asia, we briefly review the evidence for seed and fiber remains used in textile production in this region.  相似文献
