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 a comparative analysis, it is possible to discuss how sambaqui and kaizuka appear as objects of scientific investigation and also as part of the social imaginary and the cultural landscape. Archaeology, in its trajectory as a scientific field, is influenced or even directed by the different moments of construction of a national identity and discourse. While in Brazil there is a clear cut between the past and the building of a nation, situating sambaqui in the realm of the other, in Japan, the continuum from a past beyond records encompasses and situate the kaizuka within the social imaginary as part of the national narrative.  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

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

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

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

Trouvadore was one of numerous illegal slave ships taking Africans from Africa after Britain had outlawed the slave trade in 1807. The vessel wrecked off the coast of East Caicos, Turks and Caicos Islands in 1841 and 168 of the survivors entered the local community, increasing the population by 7%. The Trouvadore Project, led by the Turks and Caicos National Museum, is uncovering the story of Trouvadore and the cultural legacy of the survivors. Bringing together many disciplines, including archaeology, this project provides information about Trouvadore for the present population of the Turks and Caicos, many of whom are direct descendants of the African survivors.  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

Seasonality studies are a staple of Great Plains archaeology, but obtaining evidence for seasonal food procurement is challenging. This study explores seasonality through the lens of fetal bison remains. A method is developed that produces intra-annual probability distributions for the date of fetal death. These distributions are informed by osteometric data from fetal bison in archaeological contexts, fetal skeletal growth curves, and data-driven models of bison conception dates. Probabilities can be assigned to seasonality hypotheses by examining date intervals across these intra-annual distributions. This method is implemented through an R program and applied to seasonality hypotheses at three archaeological sites containing fetal bison remains: Big Goose Creek (Wyoming), Baker Cave III (Idaho), and the Upper Tucker Site (Texas). Unlike previous efforts to infer seasonality from fetal bison remains, this method provides explicit probabilities showing the level of agreement between the osteometric data and seasonality hypotheses. This probabilistic approach could be extended to seasonality studies involving other animal taxa both within and outside of North America.  相似文献
