Archaeological research at the UNESCO World Heritage site of Teotihuacan (ad 1–ad 550) in the Basin of Mexico provides evidence for leporid (cottontails and jackrabbits) breeding and/or management within a residential complex of the city, Oztoyahualco. The present study tests this notion by analyzing Teotihuacan leporid bone collagen samples (n = 134) for stable isotope ratios of carbon (δ13Ccollagen) and nitrogen (δ15Ncollagen) to provide information on ancient leporid diet and ecology. Results demonstrate that carbon-stable isotope values from Oztoyahualco specimens are significantly higher than those from other contexts at Teotihuacan and from a sample of modern specimens from the region. These data are consistent with the notion that leporids from Oztoyahualco consumed diets high in C4 and CAM plants, such as the human-cultivated staples of maize (Zea mays), nopal cactus (Opuntia sp.), and maguey (Agave sp.). Nitrogen-stable isotope results show no significant differences between Oztoyahualco and other contexts, suggesting that Oztoyahualco leporids inhabited similar environments, ate food grown on similar soils, and were feeding at the same trophic level. When considered in combination with archaeological data and previously published isotopic results, δ13Ccollagen data from Oztoyahualco support the idea that leporids were artificially provisioned by humans, consistent with the hypothesis that they were bred and/or managed through human labor. More broadly, these results hint that food production at Teotihuacan was at least in part conducted by specialized workers in a manner similar to that of commercialized market economy of the later Aztec Empire (ad 1428–1521).  相似文献

This article addresses early work on partial recovery that followed small motor cortical lesions. Leyton and Sherrington (1917 Leyton, ASF and Sherrington, CS. 1917. Observations on the excitable cortex of the chimpanzee, orang-utan and gorilla. Q J Exp Physiol, 11: 135222.  [Google Scholar]) studied the motor cortex in apes, hoping to learn more about the contralateral muscle representations. Then they placed small lesions within the precentral cortex, followed by a loss of the contralateral muscle twitches. The sudden loss remained for about one week, but recovery was observed and continued for weeks, up to a standstill. Sherrington and Graham Brown (1913) Graham Brown, T and Sherrington, CS. 1913. Note on the functions of the cortex cerebri. J Physiol (Lond), 46: xxii [Google Scholar] observed the same results in a serial, chronic experiment on a chimpanzee. The brain was sent to Monakow's Brain-Institute in Zurich for investigating the lesions and the degeneration pattern. Constantin von Monakow (1853–1930) had been a pioneer on recovery after acute lesions, coining the term “diaschisis.” During WWI, Graham Brown and Stewart (1916) Graham Brown, T and Stewart, RM. 1916. On disturbances of the localization and discrimination of sensations in cases of cerebral lesions, and on the possibility of recovery of these functions after a process of training. Brain, 39: 348454. [Crossref] [Google Scholar] studied a soldier in a British army hospital who suffered from a cerebral gunshot wound, localized in the sensorimotor cortex. Early and prolonged rehabilitation was successful. In 1950, Glees (1909–1999) and Cole (Oxford) placed a small motor-cortical lesion in macaque monkeys; for a few days, the monkeys had difficulties and were slow for the task. Daily training was resumed and recovery was accelerated by alimentary reward. Finally, Lashley (1890–1958) understood that handicapped patients “achieved their goal with variable means.” This demonstrated the value of active and prolonged rehabilitation, in addition to the (passive) recovery of function.  相似文献

Abstract

Recent health scares such as BSE have contributed to the growth of local farmers' markets and consumption of organics sourced globally (Morgan et al., 2006 Morgan, K., Marsden, T. and Murdoch, J. 2006. Worlds of Food: Place, Power and Provenance in the Food Chain, Oxford: Oxford University Press.  [Google Scholar]). Yet a central question about alternative agro-food networks (AAFNs) is whether they supply undemocratic diets chiefly for elites (Goodman, 2004 Goodman, D. 2004. Rural Europe redux? Reflections on alternative agro-food networks and paradigm change. Sociologia Ruralis, 44(1): 316. [Crossref], [Web of Science ®] [Google Scholar]). This is relevant to government campaigns such as ‘Generation Scotland’ and ‘5 A Day’ in the UK, and ‘Food Pyramids’ in the US, which promote better diets for their entire populations. Firefighting is risky work and because firefighters inhabit middle rungs on the socioeconomic ladder, and food is seen as key to morale and fitness, they are suitable consumers to query on food and risk. This firefighter survey presents evidence that alternative foods are gaining value in the UK and US study areas used here. Though Newcastle, UK, lags behind Seattle, US, on a continuum from conventional to alternative food systems, consumption of alternative foods by Newcastle firefighters is greater than that of workers surveyed in Edinburgh a decade before (Tregear, 1994 Tregear, A., Dent, J. B. and McGregor, M. J. 1994. The demand for organically-grown produce. British Food Journal, 96(4): 2125. [Crossref] [Google Scholar]), implying that northern UK diets could turn greener if availability and prices improve. Reasons why organic preference seems stronger among firefighters in northwestern US, than in northern UK where local preference appears stronger, are discussed, as well as theorisation of consumer response to a variety of risks over time.  相似文献

The M w7.9 Wenchuan earthquake produced a rich set of over 1,400 accelerograms, which helped us to better understand strong ground motions from such a large event. Using the abundant data, we investigated the characteristics of response spectral accelerations from this event. This study includes: the spatial distribution of spectral amplitudes at three periods selected to represent ground motions at short, short-middle, and middle-long period ranges; attenuations of response spectral accelerations at periods between 0.05 and 10 s; comparison between the observed ground motions and predicted motions from empirically based equations [Abrahamson and Silva,1997 Abrahamson, N.

Based on these analyses, we finally drew some conclusions regarding the engineering characteristics of spectral accelerations from large earthquakes, such as Wenchuan of M w 7.9.  相似文献

Rivista Italiana di Palaeontologia, 19: 3347.  [Google Scholar] was described on the basis of an almost complete enrolled specimen from the Ordovician (probably the early Llanvirn Yangtzeella poloi Biozone) of southern Shaanxi, China.

This paper aims to show how young people in former East Germany respond to the globalising processes that are part of the transformation of their society from a state-socialist to a capitalist one. It focuses particularly on the differential ways in which young people perform their identities as global/local subjects through the uses that they make of urban space. While emphasising the agency of young people, the paper seeks to examine the dialectic between globalising forces that are largely beyond their control and the negotiation of these forces in everyday practices of identity-formation. Conceptually, the paper draws particularly on the work of Beck (2000) Beck, U. 2000. “What is Globalization?”.

Haig, D.W., October 2017. Permian (Kungurian) Foraminifera from Western Australia described by Walter Parr in 1942: reassessment and additions. Alcheringa 42, 37–66. ISSN 0311-5518.

Exceptionally well-preserved siliceous agglutinated Foraminifera originally recorded by Walter Parr in 1942 are redescribed and illustrated by rendered multifocal reflected-light images. Significant new observations are made on wall texture and apertural morphology. The specimens are from the Quinnanie Shale and lower Wandagee Formation in the Merlinleigh Sub-basin of the Southern Carnarvon Basin, a marginal rift that splayed from the East Gondwana interior rift. During the Early Permian, a restricted shallow sea inundated the rift. The formations are part of sequence III of the Byro Group and belong within the Kungurian Stage (Cisuralian, Lower Permian). Of the 14 agglutinated species described by Parr, six are retained under their original names, viz., Hyperammina coleyi Parr, 1942 Parr, W.J., 1942.

Regional syntheses based on data recovered mostly from outside of the Northern Range have characterized the mountainous region in northern Trinidad as a boundary between two distinct interaction spheres during the Early Ceramic Age (ca. AD 350–650/800) (Boomert 2000 Boomert, A. 2000. Trinidad, Tobago and the Lower Orinoco interaction Sphere: An Archaeological/Ethnohistorical Study. Alkmaar: Cairi Publications. [Google Scholar]). Changes occurring on Trinidad, other islands of the southern Lesser Antilles, and the South American mainland resulted in the disintegration of these earlier style zones during the final centuries of the Early Ceramic (Boomert 2000 Boomert, A. 2000. Trinidad, Tobago and the Lower Orinoco interaction Sphere: An Archaeological/Ethnohistorical Study. Alkmaar: Cairi Publications. [Google Scholar], 2010). This period of Late Ceramic cultural realignment was characterized by climate change, the renegotiation of political and social networks, and demographic transformations. We consider newly recovered ceramic evidence from the central Northern Range in order to evaluate the characterization of the region as a boundary and the region's role in broader Caribbean trends. We examine participation in interaction spheres to provide a more nuanced understanding of regional dynamics as they were expressed locally. Ceramic data indicate that occupants of the central Northern Range interpreted regional styles using locally derived materials, thus simultaneously engaging regional traditions and constructing local patterns of resource exploitation.  相似文献

As participatory methodologies gain popularity and are increasingly adapted to carry out research with ‘children’, I return to the methodological question: is doing research with children different from doing research with adults? (Punch, 2000 Punch, S. 2000. Research with children the same or different from research with adults?. Childhood, 9(3): 321341. [Web of Science ®] [Google Scholar]). As a participatory researcher, I raise concerns around methods designed for ‘children’ that stamp a ‘how-to-research’ label upon a diverse group of individuals prior to entering the research space. Rather than continue the well-worn debate around the incompetent/competent/powerless child versus the competent all-powerful adult, I attempt a different approach that aims to dissolve this dichotomy. I draw on hybrid theories of identities (Benhabib, 1992 Benhabib, S. 1992. Situating the Self, New York: Routledge.  [Google Scholar]; Butler, 1990 Butler, J. 1990. Gender Trouble: Feminism and the Subversion of Identity, London: Routledge.  [Google Scholar]; Adams, 2006 Adams, M. 2006. Hybridising habitus and reflexivity: towards an understanding of contemporary identity?. Sociology, 40(3): 511528. [Crossref] [Google Scholar]), that recognise identities as multiple and fluid, and present social identities as unhelpful guides in designing participatory methods, principally the mythical notion of the competent all-powerful adult (Lee, 2001 Lee, N. 2001. Childhood and Society: Growing Up in an Age of Uncertainty, Milton Keynes: OUP.  [Google Scholar]). I present the case that pre-labelling participants contradicts the bottom-up approach of participatory methodologies, particularly when Participation is understood as spatial practice (Kesby, 1999 Kesby, M. 1999. Beyond the Representational Impasse? Retheorising Power, Empowerment and Spatiality, mimeo [Google Scholar]; Cornwall, 2000), and participants are invited into a research space, where identities are performed (Thrift, 2000) and are, therefore, something we ‘do’ not ‘have’ (Butler, 1990 Butler, J. 1990. Gender Trouble: Feminism and the Subversion of Identity, London: Routledge.  [Google Scholar]).  相似文献

The concept of ontological security has been taken up in human geography primarily through Giddens' (1990 Giddens, A. (1990) The Consequences of Modernity. Cambridge: Polity Press. [Google Scholar], 1991 Giddens, A. (1991) Modernity and Self-Identity. Cambridge: Polity Press. [Google Scholar]) formulation, but the idea has its origins in the writings of the existential psychoanalyst R.D. Laing. Returning to the psychoanalytic underpinnings of the concept, I use autobiographical vignettes to evoke and explore what it means to feel insecure. Using psychoanalytically informed illustrations of melancholia, ordinary acute anxiety and unconscious splitting, I develop a personal, subjective emotional geography of insecurity, and I caution against confusing certainty with ontological security.  相似文献

Lead-rubber isolators represent a valid and economic solution for the seismic isolation of bridge structures and modern manufacturing techniques make available large devices. Velocity effects on small to medium-scale isolators have been discussed by several authors (e.g., Clark et al., 1997 Clark, P. W., Aiken, I. D. and Kelly, J. M. 1997. Experimental studies of the ultimate behavior of seismically isolated structures, Berkeley, CA: Earthquake Engineering Research Center, University of California. Report No. UCB/EERC-97/18 [Google Scholar]; Thompson et al., 2000 Thomson, A. C., Whittaker, A. S., Fenves, G. L. and Mahin, S. A. 2000. “Property modification factors for elastomeric seismic isolation bearings”. In Proceedings of the 12th World Conference on Earthquake Engineering, New Zealand: Auckand. January [Google Scholar]) as well as included in reports of experimental programs (e.g., CERF, 1999 CERF. Civil Engineering Research Foundation, Summary of evaluation findings for the testing of seismic isolation and energy dissipation devices. CERF Report No. 40404. 1999.  [Google Scholar]). Only recently, however, the behavior of large devices was validated under full-scale displacements, loads, and velocities.

In this article, results obtained from an experimental investigation on the effects of axial load and strain rate on the performance of a full-scale lead-core elastomeric bearing for bridge applications, are reported. The bearing response was analyzed with particular attention to the variation of critical performance characteristics in order to produce a set of information that could be implemented in a physically motivated numerical model.

The results, in line with additional tests performed on similar full-scale bearings at the Caltrans SRMD Testing Facility at the University of California San Diego, indicate a moderate effect of the applied vertical load but a significant effect of the strain rate and cycling on all the significant response parameters. This information should be taken into account by designers, particularly when high component of velocities are associated with the expected seismic motion. A simplified numerical model is proposed for the assessment of lead-rubber bearing performance.  相似文献

The question of globalisation has become a focus of intense debate on the French Left with growing attempts to redefine the nature and forms of leftist opposition. More than any other grouping Attac, created in 1998, has been at the centre of a movement of opposition that contests the terms of neo-liberal globalisation and posits an alternative vision of social and political change. This article focuses on Attac's role in constructing a new discourse of opposition in relation to a global economic order. Whilst Attac seems to offer the possibility for ideological renewal on the Left, it has so far been unable to mobilise widespread support behind its political project. For some observers, Attac has failed to make explicit the connections between particular social problems and grievances in France and a universal context of change at international level. It tends to treat globalisation as an abstract ‘scientific’ problem, a distant and reified phenomenon rather than a social reality affecting millions of French citizens in their everyday lives.

Comment cela s'appelle-t-il, ce moment o[ugrave] un autre monde devient possible? Cela a un très beau nom, camarades. Cela s'appelle l'aurore.1 ?[1] Ramonet, I. (2002 Ramonet, I. 2002. “Cela s'appelle l'aurore”. In Attac au Zénith, 1325. Paris: Mille et Une Nuits.  [Google Scholar]) ‘Cela s'appelle l'aurore’, in Attac au Zénith, Attac, Mille et Une Nuits, Paris, p. 21. The slogan un autre monde est possible was first devised by Attac and has since become the main symbolic reference for the French anti-globalisation movement.   相似文献

Plusquellec, Y. &; Wright, A.J., October 2017. Revision of the Early Devonian tabulate coral Pleurodictyum bifidum from New South Wales. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

The tabulate coral Pleurodictyum bifidum Jones, 1944 Jones, O.A., 1944. Tabulata and Heliolitida from the Wellington district, N.S.W. Journal and Proceedings of the Royal Society of New South Wales 77, 3339. [Google Scholar], from the Early Devonian (Pragian or lower Emsian) Garra Formation of central New South Wales, Australia is revised on the basis of the holotype and three other specimens. It is selected as the type species of the new monotypic genus Bifidomeria (Family Roemeriidae), which differs from Roemeria in its strictly cerioid corallum, its bifid septal spines and aspects of its microstructure. Study of the detailed microstructure of two other tabulate corals from the Devonian of New South Wales has led to the following revised generic assignments: Michelinia progenitor Chapman, 1921 Chapman, F., 1921. New or little known fossils in the National Museum. Part XXV—some Silurian tabulate corals. Proceedings of the Royal Society of Victoria 33, 212225. [Google Scholar], previously assigned to Roemeripora, is assigned to Roemeria, and Holacanthopora clarkei Wright &; Flory, 1980 Wright, A.J. &; Flory, R.A., 1980. A new Early Devonian tabulate coral from the Mount Frome Limestone, near Mudgee, New South Wales. Proceedings of the Linnean Society of New South Wales 104, 211219. [Google Scholar] is assigned to Michelinia.
