Avian resource depression or intertaxonomic variation in bone density? A test with San Francisco Bay avifaunas

Previous analyses of the Emeryville Shellmound fauna suggested that ever-expanding late Holocene human populations of the San Francisco Bay area depressed a wide range of vertebrate taxa, including cormorants (Phalacrocorax), geese (Anserinae), and large shorebirds (e.g., Numenius, Limosa). Far-reaching implications for prehistoric human behavior, historical ecology, and modern conservation biology have resulted from that work. We test the generality of the bird-based conclusions here by documenting temporal trends in avifaunal abundances from five additional sites located on the San Francisco Peninsula. Analyses of these data reveal patterns identical to those found at Emeryville, showing significant declines through time in the relative abundances of both geese and cormorants between about 2000 and 700 B.P. New photon absorptiometric-based density data for cormorants, geese, and ducks (Anatinae) are used to determine if the declines through time in the relative abundances of geese and cormorants are correlated with variation in the extent of density-mediated attrition observed in these faunas. The data and analyses presented here suggest that while density-mediated attrition played a role in structuring element abundances in these avifaunas, there is no evidence that it varied systematically through time to produce the revealed patterns in taxonomic abundances. Resource depression thus remains a viable hypothesis for the declining abundances of large-sized waterbirds during the late Holocene of the San Francisco Bay region. The new bone density data we present should be useful to analyses of archaeological and paleontological avifaunas wherever these or related taxa are found around the world.     

The regional impact of the channel tunnel: Qualitative and quantitative analysis

The paper addresses the question of how different types of regions mill be affected by the development of a major new transport infrastructure such as the Channel Tunnel. It summarizes a study on the regional impacts of the Channel Tunnel throughout the European Union (EU). The research design combined qualitative methods of futures exploration employing 13 regional case studies with quantitative forecasting techniques using the MEPLAN transport and economic model. The paper presents the methodology and major results of the two approaches with respect to the impacts of the Channel Tunnel on transport flows and regional development in Europe and draws conclusions for transport and regional policy of the EU. The paper demonstrates that the removal of a bottleneck like the Channel Tunnel does not necessarily induce economic gains in all adjacent regions. Much more important for regional economic development than the reduction of transport costs are the image to be a region well integrated into the European high‐speed transport network and an active political response of the region to take advantage of opportunities like the Channel Tunnel.     

Re–evaluating Subsistence Skills of Levantine Middle and Upper Palaeolithic Hunters: A Comparison of the Faunal Assemblages

It has long been argued that there were qualitative differences in the procurement strategies of the Middle and Upper Palaeolithic, with the hominids of the earlier period being less capable and efficient hunters than those of the subsequent period. This hypothesis is tested here through an examination of faunal assemblages from the two periods in the Levant by comparing measures of species diversity. It is concluded that no significant differences in hunting can be documented and that the hominids of both periods can be characterized as efficient foragers.     

Between Large-N and Small-N Analyses: Historical Comparison of Thirty Insurgency Case Studies

Abstract

The authors study the 30 insurgencies occurring between 1978 and 2008 using four methods crossing the qualitative/quantitative divide. The four approaches are narrative, bivariate comparison, comparative qualitative analysis, and K-medoids clustering. The quantification of qualitative data allows the authors to compare more cases than they could “hold in their heads” under a traditional small-n qualitative approach, improving the quality of the overall narrative and helping to ensure that the quantitative analyses respected the nuance of the detailed case histories. Structured data-mining reduces the dimensionality of possible explanatory factors relative to the available observations to expose patterns in the data in ways more common in large-n studies. The four analytic approaches produced similar and mutually supporting findings, leading to robust conclusions.     

石质文物病害机理研究

导致石质文物产生病害的因素很多,其中近年来日益加剧的环境污染带来的病害加速问题引起文物保护工作者的广泛关注。精确的病害诊断是文物保护的先决条件,因此,多学科综合研究和新技术不断引进到病害机理研究方面。对各种可能的病害原因从最初的定性分析逐渐转变到定量模拟分析方面。目前,石质文物病害研究从地质勘察、室内试验、现场试验等各个方面展开,但是由于各个试验条件不同,会出现不一致,甚至相悖的结论。在对石质文物病害的研究现状进行了总结后,认为试验体系标准的制定可以使得文物保护工作者的研究具有可比性,从而可以得出较具一般性的结论,这也是进行病害机理研究的基础。由于文物完整性保护的特殊要求,无损检测技术的发展及检测结果的判定是整个的试验体系中一个重要方面。同时,由于室内实验存在时间及尺寸等比例效应问题,室外长期观测试验应是今后的研究方向。最终将病害严重程度及发展趋势的判定和有效预防发展成为一个科学体系。     

From Head‐hunter to Organ‐thief: Verisimilitude,Doubt, and Plausible Worlds in Indonesia and Beyond

In the last few years, occult head‐hunters – elusive figures that have haunted communities and the public imagination in Indonesia since at least colonial times – appear to have adopted a novel and troubling tactic. Instead of decapitating their victims and using the heads in construction rituals as they are said to have conventionally done, head‐hunters are now allegedly harvesting their victims’ organs to sell them on the global market of body parts. Based on a comparison of ethnographic material from North Maluku, a province in the eastern part of Indonesia, and news reports in regional and national papers, I trace how accounts about headhunting have morphed with narratives about organ theft. I argue that this plasticity is not a merely a change in symbolic ideas of the occult that reflects changing political and economic realities. Rather, I propose that their turn to organ theft enrols head‐hunters in a contemporary and global ‘travelling package’ that includes and entangles organ trafficking practices, media accounts, political imaginaries, and social anxieties within the same field of reality and possibility, a field of verisimilitude in which fiction and fact, rumour and reality, are fundamentally blurred. The article proposes a ‘more‐than‐representational’ approach to the organ‐stealing head‐hunter that sees him not just as a representation of particular political and historical circumstances but as a co‐producer of these circumstances, of particular political worlds and their attendant scales of anxiety. This approach, I argue, challenges the epistemological distinction between symbolic representation and political reality that informed (but also incommoded) the analyses of headhunting rumours in the 1980s and 1990s – and that continues to inform anthropological analyses of ‘the occult’ more generally.     

The Declaration of Independence: A Global History

Twenty years after the publication of John MacKenzie's Empire of Nature, his characterisation of sport hunting tourism as a symbol of elite and imperial privilege remains strong. Using the example of two white hunters from New Zealand and their trip to Northern Rhodesia (Zambia) in 1926, this article elaborates upon MacKenzie's brief mention of hunters in Africa from cultures other than Britain. In particular, the article argues that ‘home’ hunting cultures—in this case of New Zealand—need to be considered thoroughly when examining meanings of hunting tourism, and, second, that hunting trips could serve a range of purposes beyond the notion of reinforcing colonial rule.     

Native Toponymy and territorial rights

Native place names are landmarks which may provide quantitative and qualitative evidence usefully referred to for the land claims question. This paper describes the context and the method of a research project which draws from the lower Mackenzie Valley toponymic data of the last century some useful conclusions related to the actual native land claims in that region.     

Quenching the Thirst: The Cost of Water in Fragile Environments

Public policy has often addressed the problems of water supply and sanitation from the supply side to the neglect of demand side aspects in developing countries like India. This policy has not only rendered a large number of projects financially unviable but has also resulted in inadequate coverage of aspects such as population and ecological unsustainability. This article, based on household level information from six villages in a water scarce region of India (Rajasthan state), examines inter- and intra-village variations in water use and the costs, direct and indirect, involved in obtaining water. It also estimates households' willingness and ability to pay for water, using the contingent valuation method (CVM). Using qualitative as well as quantitative methods, it is argued that it is the failure of government policy and of institutions which has led to severe water shortages in harsh environments rather than supply or financial bottlenecks per se. While the estimates of price elasticity of water use indicate the feasibility of water pricing in the rural areas, the willingness to pay estimates question the general assumption that rural households are willing to pay 5 per cent of their income/expenditure for water. Various economic and extra economic factors such as household income, low opportunity costs of women and children, and attitudes towards female labour and public goods are vital in influencing the households' willingness to pay for water.     

Deciphering bone depositional sequences in caves through the study of manganese coatings

The presence of black-coloured bones in caves has been sometimes associated to the use of fire by humans, but more frequently the agent responsible for black colour is the natural deposition of manganese oxides. Manganese coatings were not usually studied once human action was discarded. However, they can provide valuable information about the origin and the sequence of formation of a palaeontological or archaeological deposit. In this paper, we present a quantitative and qualitative study of the manganese coatings that affect most of the bones recovered in the palaeontological site of Liñares cave (NW of Iberian Peninsula) together with other taphonomic marks. The manganese coatings are superimposed on other features previously existing on the surface of the bones. In turn, the coatings can be affected by other agents that modified them totally or partially. The combined interpretation of the different taphonomic marks provides us with valuable information on the sequence where the different taphonomic processes were produced, as for example the intervention of carnivores in the disarticulation of some elements before the burial, the preservation of anatomic connections until after the burial of the carcasses, and the existence of reworking processes in some parts of the infill.

Cluster analysis of mixed-level data: Pottery provenience as an example

Provenience or “sourcing” studies of archaeological objects most commonly employ quantitative measurements of amounts of chemical constituents in the artifacts and source materials. These are then used in statistical grouping procedures known as cluster analyses. Many additional attributes of artifacts and sources, yielding lower-level qualitative data, are also of potential importance in determinations of artifact origins. These attributes are usually neglected because of the longstanding difficulty in treating “mixed-level” data, that is, combining both qualitative observations and quantitative information in a single powerful statistical procedure. A series of cluster analyses were run on two data sets consisting of archaeological pottery, using mixed-level characterization data in the CLUSTAN program with Gower's coefficient of similarity. The clustering solutions are interpretable in terms of provenience and production strategies.     

The Misuse of Area in Mapping Census-Type Numbers

Abstract

Polish lands in 19th century are usually located in the economic peripheries of Europe. However there are no usable datasets of Polish GDP for this period to verify this hypothesis. The main problem is lack of reliable and comparable macroeconomic data from country divided between Russia, Austria and Prussia. The main goal of this research was to propose the method based on the urbanization data set to estimate the GDP of Polish territories and to verify the hypothesis on the peripheral development of Polish lands. In result the new estimates on GDP per capita were established, that allowed to confirm the hypothesis of semi-peripheral development of Polish territories in 19th century and slow process of catching-up with the core economies.     

Age at death estimates for the protohistoric Arikara using molar attrition rates: A new quantification method

Dental attrition is positively related to ageing and has often been used to determine age at death of animals and prehistoric/historic humans. A newly designed molar-attrition-scoring standard was applied to a protohistoric skeletal sample, the Arikara (N = 143) from the North American Plains. Several criteria are used in producing a molar tooth crown wear (MTCW) score. These include: (i) the size of enamel wear facets, (ii) the amount of dentine and secondary dentine exposure, (iii) the height of the tooth, (iv) the enamel rim thickness, and (v) the amount of pulp-cavity exposure in the advanced stages. Age-at-death estimates were generated from ordinary least-squares (OLS) analysis, with estimated age regressed independently on the total molar attrition score (TMAS), mean molar-1 tooth crown wear (ȲM1TCW), mean molar-2 tooth crown wear (ȲM2TCW), and mean molar-3 tooth crown wear (ȲM3TCW). In all analyses (with the exception of the third molar), the coefficient of determination (r²) revealed a strong relationship between molar attrition and age. Multiple-regression analysis revealed a significant sex difference in molar-attrition rates. Besides intercept and slope differences, the female scatter showed greater molar attrition variation than the male scatter. There was no statistical difference between mean upper molar attrition score (UMAS) and lower molar attrition score (LMAS). There was no significant difference in molar attrition rates by side, and side by molar tooth.     

Hunting and Scavenging by Early Humans: The State of the Debate

During the last 25 years, there has been a shift towards the belief that early humans were scavengers instead of hunters. This revisionist interpretation has brought a reconciliation with the Darwinian paradigm of gradual progressive evolution that has traditionally guided (and very often, misled) an important part of anthropological thinking. However, empirical support for the scavenging hypothesis is still lacking. Recent data based on bone surface modifications from archaeological faunas suggest, in contrast, that hominids were primary agents of carcass exploitation. Meat seems to have been an important part of Plio-Pleistocene hominid diets. Passive scavenging scenarios show that this kind of opportunistic strategy cannot afford significant meat yields. Therefore, the hunting hypothesis has not yet been disproved. This makes the hunting-and-scavenging issue more controversial than before, and calls for a revision of the current interpretive frameworks and ideas about early human behavior.     

Occlusal molar microwear and the diets of the Ipiutak and Tigara populations (Point Hope) with comparisons to the Aleut and Arikara

Archaeological excavations at Point Hope, Alaska uncovered skeletal remains of two populations: the Ipiutak (100 B.C.–500 A.D.) and Tigara (1200–1700 A.D.). Archaeological evidence indicates that, although both groups relied on animal (largely marine) resources for their subsistence, the Ipiutak were mainly caribou hunters, whereas the Tigara were primarily whale hunters. To date, no study has attempted to ascertain whether the inferred dietary differences of these two groups could be substantiated using a more direct technique, e.g. microwear or stable isotope analysis. In this study, the occlusal molar microwear fabrics of the Ipiutak and Tigara were analyzed. Comparative data for two other modern human groups, the Aleut and Arikara, were also examined. Significant differences in microwear signatures were detected among the groups considered. The results of this study show that the Tigara have significantly more microwear features, more pits and narrower scratches compared to the Ipiutak. These results are concordant with interpretations that the two Point Hope populations had significantly different dietary habits. Differences in microwear signatures between the Aleut and the two Point Hope populations were also detected. Compared to the two Point Hope populations, the Aleut has significantly fewer features and wider scratches. The Aleut microwear signature further differs from that of the Tigara in having significantly lower pitting incidence. The microwear pattern of the Arikara, who had a mixed diet, differed from that of the mainly meat-eating Aleut and Point Hope peoples in that the Arikara has significantly fewer features, lower pitting incidence and narrower scratches.     

Where the heart is: home space transitions for residential college students

Home and the transition to adulthood are related temporal and spatial constructs. Building upon Kenyon’s [1999. “A home from home: Students’ transitional experience of home.” In Ideal homes? Social change and domestic life, edited by T. Chapman, 84–95. New York: Routledge] categorization of physical, social, personal, and temporal elements of home for college students, we analyze survey responses from 256 students at a 4-year U.S. residential college in order to uncover how perceptions of home-like spaces change as students move from pre-college homes, through on- and off-campus home spaces, and toward imagined future homes. Our quantitative findings show that the four home elements matter differently across time and type of home, supported by qualitative findings wherein students articulate how they conceptualize similarities and differences between the different home spaces. This study adds to ongoing conceptualizations of the transition to adulthood as placed (for four-year residential college students especially), and as fluid and multilayered in terms of social actors’ views of their past, present, and imagined future homes and accompanying identity transitions.     

Armenian women of Istanbul: notes on their role in the survival of the Armenian community

This article argues that the Armenian women living in Istanbul are confined to domestic and communal spaces, and that the roles of symbolizing collective territory and identity, and of cultural reproduction of the community, are mostly associated with women. The data and observations we explore here are based on a field survey of Turkey's Armenian community that was conducted in Istanbul between November 2004 and May 2005. Evaluation of this survey based on both quantitative and qualitative methods allows us to draw some conclusions about the roles of Armenian women in the reproduction of Armenian culture. Women's roles indirectly influence Armenian identity, creating the conditions for its survival.     

Hydrodynamic sorting in a coastal marine skeletal assemblage

In this paper I evaluate the effects of wave and tidal erosion on element‐specific measures of phenotypic variability. Previous research has found a high correlation between skeletal weight, shape, and density and the transport potential of an element exposed to hydrodynamic forces. However, no previous studies have attempted to address the issue of within‐element sorting based on selective removal of only the smallest members of a given element class. I evaluate this hypothesis using a human skeletal sample from Bird Island (8DI52) located in Dixie County, Florida. This sample comprises two components, an eroded sample that was exposed during severe storm and tidal activity, and an uneroded sample excavated from primary context. The measurement‐specific means for the subcomponents were compared using Student's t and Wilcoxon tests and variability differences were evaluated based on standard deviations, coefficients of variation, and maximum/minimum indices. The data included maxillary and mandibular tooth dimensions and postcranial metrics. No evidence for selective winnowing based on within‐element size was found in this data set.

HAM HILL STONE: A MEDIEVAL DISTRIBUTION PATTERN FROM SOMERSET

This paper explores the potential of simple quantitative techniques for elucidating a medieval distribution pattern. The distribution is that of a distinctive building-stone found in parish churches in Somerset and throughout the south-west. Dating is achieved by recognition of different architectural styles and the stone's occurrence is plotted within 25 km of the source quarry at Ham Hill near Yeovil. The study has dual implications in that simple statistical techniques enable new conclusions to be made concerning the mechanisms of the stone's distribution, but some of these conclusions can also be checked against the documentary evidence. Therefore both distribution and techniques come under scrutiny. In this way a complementary archaeological and historical approach united by quantitative techniques and documents is applied to a medieval distribution problem but has implications for the prehistorian also.
