Barrio resurgence in Buenos Aires: Local autonomy claims amid state-sponsored transnationalism 总被引:1,自引:0,他引:1
J. Miguel Kanai 《Political Geography》2011,30(4):225-235
This paper argues that observing neighborhood movements through the lens of territorial state restructuring holds theoretical promise. Contemporary struggles over municipal decentralization need to be located within broader state re-scaling processes. Seeking to contribute a Latin American perspective to the largely Anglo-American field of urban neoliberalization research, this study engages with the emergence of local autonomy claims in Buenos Aires, Argentina. Middle-class activists and organizations advanced such claims against the background of thorough transnationalism, in what may be interpreted as a localist political reaction to the socio-spatial consequences of urban and state restructuring. Field evidence is used to assess the ultimate political efficacy and democratic implications of their political agency, particularly in what concerns municipal decentralization. It is argued that curtailing the empowerment of barrio districts were the following conditions: mayoral opposition to communal reforms; ongoing cross-scalar tensions between the city and national government; and the barrio-centric issue framings of activists, which hampered social recruitment in an increasingly heterogeneous and transnationalized urban space. 相似文献

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours. 相似文献

The paper deals with dendrochronological and radiocarbon dating of subfossil trunks found in the basin of the Morava River.
The research into subfossil trunks had been conducted in the Czech Republic in the past but the research stopped in 2001.
160 records of measurements of subfossil, predominantly oak trunk samples, are preserved from that time. Three years ago the
research was reopened and again the most trunks were found in the basin of the Morava River. 92 samples of oak trunks and
7 samples of other tree species (poplar, elm, maple, beech) were taken from selected sites. The samples were processed in
compliance with the standard dendrochronological methodology. To date the samples, Czech, Austrian, Polish and German standard
chronologies were used. In cases when the dendrochronological dating was unsuccessful, the samples were sent for radiocarbon
dating. In total, 35 samples were dated, mainly by the radiocarbon method. Subfossil trunks from gravel pit Tovačov were dated
and classified into 4 different periods, the oldest being from 2780–2190 BC. In Osek nad Bečvou, the samples were taken from
two sites. Whereas from the 4 trunks taken in the river channel each was from a different period, the trunks from the gravel
pit come from 981–1015 AD. The trunks found in the Morava River basin near Strážnice were dated to the 10th–15th century. In the future, we expect to extend the amount of the acquired samples with the aim to create a link to the existing
standard chronology or to create a long floating average treering curve. 相似文献

We present a scheme to modify empirical Green's functions by attenuation considering: (1) geometrical spreading; (2) decay in high frequency; (3) regional attenuation; and (4) phase of the signal. The accelerograms computed with the proposed simulation method are compared, in time and frequency domains, with strong ground motions from subduction and intermediate-depth earthquakes recorded in Mexico. It is shown that this simple empirical Green's functions technique can synthesize both the shape and amplitude of the response spectra in the site, considering a postulated seismic source located at different distances from the original one. 相似文献

We present the first analysis of the influence of climate change on carbon and oxygen isotope fractionation factors for two saccharides (glucose and α-cellulose) of pine wood. The conifers grew in the Niepo?omice Forest in Poland and the annual rings covered a time span from 1935 to 2000 AD. Glucose samples from acid hydrolysis of α-cellulose were extracted from annual tree rings. The carbon and oxygen isotope fractionation factors between glucose and α-cellulose were not stable over time. The mean value for the carbon isotope fractionation factors between glucose and α-cellulose was greater than unity. The mean value for the oxygen isotope fractionation factors between glucose and α-cellulose was lower than unity. We established, with respect to climate change, the significance of the interannual and intraannual variation in the carbon and oxygen isotope fractionation factors between both saccharides. We used moving interval correlation results for May of the previous year through September of the current year using a base length of 48 years. The relationship with summer temperature is the main climate signal in the carbon isotope fractionation factor between glucose and α-cellulose. The relationship with autumn sunshine is the main climate signal in the oxygen isotope fractionation factor between glucose and α-cellulose for the tree ring chronology. 相似文献

Diverse hunter-gatherer groups inhabited Tierra del Fuego (Argentina) from the end of the last glaciation until recent dates. Sadly, the contact with European settlers was fatal for them, and a series of different causes led to their disappearance. Among these groups, Selknam inhabited the central and northern part of the Isla Grande (Tierra del Fuego) until the first decades of twentieth century. Although many travellers and ethnographers described this society, the recorded information related to vegetal resources management and plant exploitation strategies was quite scarce. As a consequence, a picture was created in which plants, and especially plant food, had a very poor role in the everyday life of these people. In this work, we present the results of the first archaeobotanical analyses carried out on an excavated site related to the Selknam hunter-gatherers. The information presented here, along with future studies, will enlarge the knowledge and enrich the image that we have of Selknam’s plant use, economy and social relations. 相似文献

Cultural policy research exists in many contexts, asks many different kinds of questions and adopts a wide repertoire of research methodologies from a raft of academic discourses. This article investigates the research questions and approaches being undertaken by those working in this field. In order to achieve this, the article draws upon readings of contemporary publications in the field and on the authors’ experiences of building a research capacity in the area of cultural policy in a British – and, more particularly, a post‐devolution Scottish – university. The article traces the emergence of an academic discipline in the field, and seeks to advance this by reviewing a tripartite research agenda investigating: the history and historiography of cultural policy; the principles and strategies of cultural policy; and, the relationships between cultural policy and cultural theory/cultural studies. 相似文献

This paper looks at the St Kitts and Nevis Mummies' plays as published in Folklore by Roger Abrahams (1968). It demonstrates that the texts were originally taken from a play published by the Victorian children's author Mrs J.H. Ewing. This play appeared in several editions, most notably in two series issued by the Society for Promoting Christian Knowledge. Mrs Ewing's text was itself compiled from three northern English chapbook texts and a version from Silverton, Devon. The relative contribution of these texts to Mrs Ewing's play, and the way she put them together, are both explored. 相似文献
