The study presents the results of neutron activation analysis (NAA) of contemporary pottery from Tigray Regional State, northern highland Ethiopia. This is the first regional-scale study of ceramic composition of Tigray’s pottery and is part of an ethnoarchaeological study of the material and social contexts of pottery production and consumption in Tigray’s Eastern (Misraqawi), Central (Mehakelegnaw), and North-western (Semien Mi’irabawi) zones. The analysis identifies clear compositional groups with strong regional patterns, an encouraging result for the use of NAA to study Tigray’s ancient pottery trade. Significantly, the study further contributes to discussions of how mutually constituted social identities of potters and consumers affect compositional patterning in the distribution of pottery in market networks.  相似文献

Based on William Morris Davis’ great Transcontinental Excursion of 1912, this article assesses and reviews the Geography by Rail® program (GbR) – a unique, short-term, field-based study abroad experience that takes an uncommon-in-the-US approach to international exploration and fieldwork, incorporating on-the-ground, regional geography-based learning experiences. Though it could be used as such, this is not intended as a “how-to” article, but instead, an examination of how the program’s alternative approach to short-term, field-based learning increases student engagement, enlivens the discipline of geography by championing the regional geography approach, and bridges the physical-human divide in geography. Examples are given of assessment techniques, relevant skills gained by student participants, student feedback received, and potential limitations of such a program. Our main goal rests in demonstrating that by being in the landscape, practicing in it, students often gain a perspective not achievable in the traditional classroom setting. In the regional and romantic geography sense, favoring breadth of learning over depth, we further argue that GbR represents a novel way to accomplish this important-yet-not-often-fostered and, oddly and unfortunately, difficult-to-find-in-geography concept.  相似文献

In Papua New Guinea (PNG) more rural people, and especially rural women, earn cash from selling in marketplaces than from any other source. PNG's marketplaces are critical for food security, and for the redistribution of wealth. They are also important meeting places where people gather to see friends, hear the latest news, attend court cases, play cards and be entertained. This introduction to this special issue on ‘Marketplaces and Morality in Papua New Guinea’ reviews the history of PNG marketplaces and their contemporary forms. It charts their transformation from introduced colonial spaces into dynamic Melanesian places, which, as places to buy, sell and socialise, have become pervasive institutions in the lives of both urban and rural Papua New Guineans, and places where people interact with both known and unknown others. From this, marketplaces emerge as important spaces of moral evaluation and contestation in relation to what constitutes morally acceptable exchange and what practices are acceptable in these places. The paper demonstrates that exchange in the marketplace should not be reduced to commodity transactions, and questions assumptions about the types of people marketplaces create. It argues that the country's marketplaces are productive sites to consider ideas of exchange, social relations and social personhood, and that there is a critical need to understand the concrete details of what takes place in contemporary marketplaces.  相似文献

This study presents a late 19th to early 18th cent. BCE, MBIIA settlement in the immediate vicinity of Tel Nami on the Carmel Coast of Israel. Site 104–106 has been all but destroyed by modern agricultural activity as well as quarrying, but a large number of ceramics and small finds were salvaged during a 1985–6 survey of Tel Nami?'s hinterland as well as subsequent geoarchaeological research of the area. Little of the site remains, and the current study functionally amounts to a salvage project for an MBIIA coastal site, which was mentioned in an earlier survey. Geomorphology reveals how the sandstone kurkar ridges in this area of the coast governed the dynamic relationship between Tel Nami and its hinterland. Comparable ceramic chronology for Site 104–106 presented derives from Aphek-Antipatris, Megiddo, Kabri, Tel Ifshar, Tel Nami itself, and other MBIIA coastal sites of the Southern Levant. The ceramics include well-produced local wares as well as imports from coastal Lebanon, Syria, and Cyprus confirmed by petrographic analyses. Finds suggest a small agro-industrial site in the immediate periphery of the coastal Tel Nami.  相似文献

A major dilemma in Gender and Development (GAD) work is why it is that sometimes women may feel better off colluding with gendered structures that ensure their continued subordination rather than seeking approaches that will allow them to break free of this. Kandiyoti (1988 Gender and Society 2 274–90) has identified this apparent collusion as 'patriarchal bargains', which offer women greater advantages than they perceive can be achieved by challenging the prevailing order. Such women are therefore reluctant to engage in empowering activities that may challenge their gendered bargain. This paper explains this dilemma in the context of GAD work undertaken with Bedouin women in Southern Egypt.  相似文献

The hydrogen isotope systematics of hair have been explored and several applications demonstrate the type of information that can be recovered from archeological and forensic hair samples. Experiment with modern hair demonstrate that sources of protein-based hydrogen in keratin are food and water. On the basis of a deuterium-enriched drinking study, it was found that 31% of hydrogen in human hair is derived from ingested water. At least 9% of total hydrogen in human hair is isotopically exchangeable with water or water vapor at 25 °C. Nearly complete exchange occurs in a matter of hours. The δD value of body water is approximately 17±10‰ (n=7) more negative than human hair, although there is much scatter in data for modern hair, which is clearly related to variability of the isotopic composition of ingested food and water. Archeological hair samples were analyzed from (i) a 370 year old Incan mummy sacrificed at 5300 m altitude in Argentina (Geoarchaeology 14 (1999) 27) and (ii) from a Woolly Mammoth from Siberia. High spatial resolution data along the length of hair from the mummy indicate seasonal variations in carbon, nitrogen and hydrogen isotope ratios. No hydrogen isotope anomalies are seen in the youngest hair at the base of the scalp, indicating that the individual probably lived at 1600 m, and spent less than a week at high altitudes before death. The mammoth also preserves a seasonal signal, suggesting hair growth rates of 33 cm/year, faster than human hair, but slower than horse tail hair. The limited isotopic range across seasons for the mammoth is consistent with a north-south migration on the order of 1000 km.  相似文献
