Before now, no palynological studies were made on shell midden deposits in Nova Scotia, despite a long history of archaeological research. A test study of samples taken from the shell midden at Maligomish (Indian Island) on the Northumberland Strait was conducted to determine if sufficient pollen, fern and moss spores, and other non-pollen palynomorphs (NPP's, including fungal remains, algal spores) could be recovered to allow interpretation of environmental conditions at the time of deposition. Several pollen processing methods were tested: sieving and swirling, chemical treatment with cold HCl, 5% KOH and brief exposure to 5% NH4OH, and treatment with acetolysis solution. We recovered variable amounts of pollen, spores and NPP's from samples taken at 3–5 cm, 5–15 cm and 15–25 cm below surface. Abundant microcharcoal fragments prevented effective use of the swirling technique, but sufficient palynomorphs were recovered by chemical treatments to allow assessment of down-section changes in assemblages. Three radiocarbon ages from Mya arenaria and Crassostrea sp., and measurements of sediment grain size, moisture, organic and inorganic carbon, provide a framework for analysing palynological assemblage changes and context for interpreting differential palynomorph preservation. Despite some oxidation and microbial degradation of palynomorphs in the time interval (ca. 380–1600 cal yr BP), the midden assemblages correlate with pollen zones from marine and lake core sites within ca. 50 km of Maligomish. Shifts in abundances of algal spores, testate amoebae and aquatic plant pollen also indicate changes in depositional conditions during the time of midden use. The study provides the first reference for archaeologists attempting to use palynology for analysis of samples from Nova Scotian shell-bearing contexts.  相似文献

In recent years it has been pointed out that regional unemployment disparities are much more entrenched across member states of the European Union (E.U.) than they are in the U.S. A 'conventional wisdom' has emerged to the effect that this difference is due in part to the greater degree of wage rigidity in E.U. regions. In this paper we explore this issue by estimating short run and long run real wage (in)flexibility for the regions in five core E.U. countries (Germany, France, Italy, the United Kingdom, and the Netherlands) and for the U.S. states for the period 1976–1994. We find that real wage (in)flexibility varies across regions both in the E.U. and the U.S., but that, on average, regional wages are no less flexible in E.U. core regions than in U.S. states. The paper also examines some of the possible correlates ofregional variations in wage (in)flexibility.  相似文献

Children, no doubt, were a significant component of Upper Palaeolithic societies. Despite this fact, however, serious identification and consideration of material culture which may have belonged to children – at least at one time during their use‐life – have not been undertaken. This situation extends to the best represented and most intensively studied of the European Palaeolithic techno‐complexes, the Magdalenian (c.21,000–14,000 cal BP), and consequently, we know very little about the children of this enigmatic people. As play, including object play, is a ‘true cultural universal’, we can be certain that Magdalenian children integrated objects into their games, with these playthings later incorporated into the archaeological record. Through examining ethnographic accounts of recent hunter‐gatherer children and reconsidering archaeological assemblages in light of these data, this paper suggests that Magdalenian playthings probably included full‐sized adult weapon tips and – more significantly – pieces of what archaeologists term ‘art mobilier’.  相似文献

In Indonesia fertility has plateaued for more than a decade. Over the same period Indonesian women have increasingly accessed contraception via the private sector. Our qualitative inquiry into the contraceptive preferences of middle class women in urban Yogyakarta revealed limited interest in and intent to use biomedical and hormonal contraceptive methods. Women’s justifications for their contraceptive choices were complex and manifold: most had concerns about safety and the side effects associated with hormonal and biomedical contraceptives; others were ideologically opposed to fertility control. We conclude that contraceptive choices were an embodiment of women’s reproductive modernity, which in turn underpinned their reproductive agency. We also problematise the extent to which women’s contraceptive choices were comprehensively informed. Women’s reproductive modernity was shaped by their socioeconomic status; access to modern communication technologies; understandings of their right to health and contraceptive choice; pious yet pragmatic religious identities; and negotiations within their marital relationships.  相似文献

In this paper, we report on a study of the psychosocial effects of child domestic work (CDW) in six countries and the relevance of our findings to international legislation. Our results suggest that CDW is highly heterogeneous. While some young child domestic workers work long hours, suffer physical punishment and are at risk of psychosocial harm, others are able to attend school and benefit from good relationships with their employers and networks of support. Child domestic workers in India and Togo were most at risk of psychosocial harm. We conclude that classification of this employment as hazardous would not be appropriate and could be counterproductive and instead propose that legislation focuses on protective factors such as a social and community support.  相似文献

By the 1970s, Christian missions to Aboriginal people in the Northern Territory were enthusiastic supporters of Indigenous self-determination, even as they sought to maintain a missionary presence in Aboriginal communities. This article asks how missions continued to seek to influence and direct Aboriginal churches and communities through espousing self-determination, and how Aboriginal leaders engaged with and exploited this apparent contradiction. Focusing on contributions to the missiological publication Nelen Yubu from Deacon Boniface Pedjert, Patrick Dodson, Miram Rose Ungunmerr-Baumann, Dyiniyini Gondarra and Alice Kelly this article considers how Aboriginal leaders and thinkers managed and challenged non-Indigenous expectations set for them around how their decolonisation was to proceed. Self-determination, for missionaries, could be achieved by a new, supposedly more enlightened mission to “inculturate” the gospel. Whereas missionaries presumed Aboriginal church leaders' authority rested in their cultural authenticity, these Aboriginal leaders were also asserting other sources of authority including their culture, but especially the authority that arises from Country itself.  相似文献

Researchers use a variety of target materials, and sometimes combinations of materials, in their archaeological experiments to examine thrust-spear or projectile penetration, impact angle, durability, and other issues involving prehistoric hunting weaponry. This variety of target materials is beneficial to archaeological science in several ways, but it may also hinder the comparison of results because many of these target materials do not necessarily share similar physical properties. Here, we assess the penetration properties of four different target materials—store-bought meat, clay, and two types of gelatin—via static penetration tests of a modern broadhead-tipped arrow and a stone-tipped projectile attached to an Instron Universal Materials Tester. Our analyses of load-deflection curves, peak load, and work energy demonstrate how the four target materials are similar in some ways but different in others, which suggests that researchers may strategically employ one or several depending on the question asked or hypothesis tested.  相似文献
