Twenty lead finds, unearthed in Late Bronze–Early Iron Age levels at the Santa Barbara nuraghe situated at Bauladu in Sardinia (Italy), have been examined. Their chemical composition has been determined using the ICP-MS plasma-mass technique (Cu, Fe, As, Ag, Sn, Sb, Bi, Zn, Cs, Tl, Mo, Cd, In, Te, W, Th, U, Li, Se). Lead isotope ratios (208/206, 207/206, 206/204) have also been determined. The results are discussed in relation to the mineral source and some aspects of the metal extraction processes. The finds are composed of high purity lead obtained using a smelting at low temperature. Based on the isotope ratios it has been possible to establish that the metal originated from Sardinian ore deposits type.  相似文献

While understanding young people has never been easy, migration trends make it increasingly difficult. Many classrooms have become culturally heterogeneous and teachers are often faced with pupils with diverse linguistic and cultural heritages. Current scholarship suggests that as a discipline, physical education has not adapted to this diversity. In fact, commentators have suggested that physical education alienates pupils from minority groups and that traditional practices work to maintain cultural difference. The broad objective of this paper is to provide insights into how physical education intersects with biographies shaped by migration. Drawing from a case study investigation, this paper presents interview data from three youths with migration backgrounds living in a German-speaking region of Switzerland. The cases were selected because they highlight various ways in which physical education (PE) comes to make sense for adolescents. The key arguments that we develop are that ethnicity often works at an implicit level in PE, that young people experience the effects of migration backgrounds in diverse ways, and that migrants themselves support official educational discourses that work to disadvantage people with migration backgrounds. A key implication is that in a cultural milieu in which generalisations are normal and sometimes considered desirable, both researchers and practitioners need to be wary of racialising discourses. As an alternative, it is suggested that focusing on individual processes can improve the conceptualisation and implementation of physical education pedagogies.  相似文献

There is a great need for effective evolution education. This paper reviews some of the evidence that demonstrates that need and analyzes some of the foundational semantic, epistemological, and philosophical issues involved. This analysis is used to provide a functional understanding of the distinction between science and non-science. Special emphasis is placed the scientific meaning of the terms theory, hypothesis, fact, proof, evidence, and truth, focusing on the difference between religious belief and acceptance of a scientific theory. Science is viewed as theologically neutral and as not mutually exclusive from religion. Finally, a number of practical recommendations to the classroom biology teacher are presented.  相似文献

This study examined the extent to which different measures of speechreading performance correlated with particular cognitive abilities in a population of hearing-impaired people. Although the three speechreading tasks (isolated word identification, sentence comprehension, and text tracking) were highly intercorrelated, they tapped different cognitive skills. In this population, younger participants were better speechreaders, and, when age was taken into account, speech tracking correlated primarily with (written) lexical decision speed. In contrast, speechreading for sentence comprehension correlated most strongly with performance on a phonological processing task (written pseudohomophone detection) but also on a span measure that may have utilized visual, nonverbal memory for letters. We discuss the implications of this pattern.  相似文献
