Oil-rich Venezuela is being hit by the largest crisis in living memory. Now, more than 4.8 million Venezuelans have fled the country in search of food and safety. News about migration and humanitarian aid dominate. Yet, many Venezuelans stay and seek alternative strategies to cope with scarcity and insecurity. Ad hoc solutions mainly depend on alternative economies in the borderlands that do not always fit within frameworks of human rights and rule of law, but do provide relief and produce opportunities along with new inequalities that (un)willingly sustain the crisis. Amid collapsing state infrastructures, these transborder economies tie into the global trade of basic supplies, narcotics, drugs, natural resources and human trafficking that operate in the interface of the legal and the illegal. The complex humanitarian crisis in Venezuela is as much about poverty and scarcity as it is about wealth and abundance benefiting only a very few. An ‘anthropology of abundance’ allows us to grasp these underlying socio-economic dynamics that turn crisis management into crisis maintenance. 相似文献

Northwestern Italian weak-motion data were used to study attenuation characteristics of horizontal peak ground acceleration (PGA) and horizontal peak ground velocity (PGV) from earthquakes of local magnitudes (M l ) up to 5.1. Data have been provided by the RSNI (Regional seismic network of Northwestern Italy) and RSLG (Regional seismic network of Lunigiana-Garfagnana) waveform database. The database consists of more than 14000 horizontal components recorded in the period 1999-2002 by both broadband and enlarged band seismometers. The accuracy of the procedure used to extract PGA values from the velocity recordings was verified comparing observed and derived PGA values at station STV2, which was equipped with both a temporary K2 Kinemctrtcs accelerometer and Guralp CMG40 broadband sensor. The attenuation of both peak ground acceleration and peak ground velocity was found to be logarithmically distributed with a strong attenuation for low distances (less than 50 km) and low M l values (<3.0). The resulting equations are: Log(PGA)=?3.19+0.87M?0.042M 2?1.92 Log(R)+0.249S, Log(PGA)=?4.23+0.76M?0.018M2?1.56 Log(R)+0.230S, where PGA is expressed in g, PGV is expressed in m/s, M is local magnitude, R is the hypocentral distance in kilometers and S is a dummy variable assuming values of 0 and 1 for rock and soil respectively. For increasing distance and magnitude, both PGA and PGV values show a linear distribution. The validity range of the obtained attenuation relationships is 0–200 km for distances and M l up to 4.5. Sensitivity studies performed by analysis of residuals, showed that predicted PGA and PGV values are stable with respect to reasonable variations of the model and distances providing the data. Comparisons with attenuation relationships proposed for Italian region, derived from strong motion records, are also presented. 相似文献

This study explores how urban youth fit the use of information and communication technologies (ICT) into their everyday lives. Their virtual mobility may be lasting and have long‐term effects on activity patterns and socio‐spatial structures. We focus on the types of activities that become ICT based, and whether the extended networks fostered by virtual mobility affect local interaction, physical mobility, and face‐to‐face meetings. The study is based on an indepth, two‐wave panel study of young people living in Gothenburg, Sweden, supplemented by national ICT‐use survey data. Results show that young people use computers for one and a half hours per day, and half of this time is spent online. Time spent on ICT use is increasing, and ICT now encompasses a broader range of activities. The Internet is mainly used to communicate with people already known in ‘real life’. Contacts are both geographically far‐flung and very local. ICT use is found to generate additional contacts and communication rather than replace telephone calls and travel. 相似文献

This article explores the relationship between class and community through a discussion of peasant struggles and the commune during the Russian Revolution. Doing so, we show how Marx's class‐oriented reflections on community can help us to understand the role that the peasantry plays (or should play) in processes of social transformation. This enables us, first, to understand the relevance of communal forms for Marx, who believed that communitarian ways of life were crucial for overcoming a value‐based society. It is, in fact, a mistake to divide Marx's intellectual trajectory into two periods: a categorical Marx, who authored Capital and critically analyzed the classical theory of value, and a phenomenological, empirical Marx, who in the last years of his life abandoned writing Capital and focused instead on studying the Russian peasantry. Second, it enables us to discuss new externalist visions, such as postcolonial and decolonial theories, which postulate that the subordination of contemporary peasant communities is rooted in epistemology, culture, and local power relations. These theories are related to the old social‐democratic canon, which conceives of social classes as preconstituted entities and of capital as a parasitic externality that is incommensurable with social dynamics. The experience of the Russian peasantry calls into question all externalist and ontological perspectives. 相似文献

The virtual access offered by information and communications technology (ICT) has entered homes to an unprecedented degree – with disputed socio–spatial consequences. This paper explores whether people's use of time and space has changed with increasing access to ICT, and it considers the role of the home and the displacement of mobile and stationary activities. Data from the Swedish Time Use Surveys for 1990–1991 and 2000–2001 reveal structural tendencies, while a panel study of urban youth details ongoing change processes. Findings indicate that from 1991 to 2001, the Swedish population spent over 80 per cent more time on virtual mobility; physical travel and media consumption also increased, albeit slightly. The total time spent at home remained stable, though certain groups, young men particularly, significantly increased both time spent at home and ICT use. The panel study found that individuals who substantially increased in‐home computer use spent more time alone at home and less time socialising; they also spent less time travelling and watching television. The amount of ICT use adapted to the available free time. 相似文献

Loom weights are common finds in archaeological excavations in Europe and the Near East. They represent the only remains of warp-weighted looms. The function of the warp-weighted loom is well known from ethnographic studies. The function of loom weights, however, has not been investigated and cannot be deduced directly from ethnographical data, since loom weights in antiquity were very different from those used in the twentieth century AD. This paper reviews the functional elements of a loom weight. The weight and thickness of loom weights are established as the defining functional parameters for the operation of the warp-weighted loom. A series of systematic tests demonstrated that the weight of a loom weight defines what yarn to use and the thread density. The thickness of a loom weight, and thus the width of the row of loom weights hanging closely together, defines the width of a fabric and – together with the weight of the loom weight – the thread count and density of the fabric. This new knowledge provides the methodological framework for archaeologists to calculate textile production possibilities from any given loom weight, as long as the weight and thickness are preserved. Furthermore, it allows scholars to assess textile production on sites where no textiles are preserved. 相似文献
