Plastic possibilities: Contrasting the uses of plastic ‘waste’ in India

This article draws on examples of inventive plastic reuse from India and personal anecdotes of elders as an anthropological reflection on possible plastic futures. It sketches the large-scale governmental reforms in the domain of municipal solid waste management, or MSWM (which, by legal definition in India, includes plastic waste). In this regard, it draws out some of the problematic socio-political and environmental implications of Prime Minister Narendra Modi's ‘Clean India’ campaign, whose technocratic policy orientations towards standardized centralized MSWM echo his cultural nationalist agenda. These reforms contrast with home-based re-engineering methods and the redeploying of plastic discards (thereby making them notuner moton (‘like new again’), and their localized circulation through relatively local but uneven reputational and economic networks. Clean India sequesters and processes vast quantities of plastics through the wide-ranging adoption of a waste-to-energy techno-fix (in which plastics are incinerated). In contrast, the authors illustrate routine practices and relations whereby people reuse, repurpose and recycle plastics. While Clean India can detract from and disrupt these mundane practices and everyday relations, these are suggestive of alternative plastic futures – both socio-material and environmental.     

PRODUCTIVITY AND THE DENSITY OF HUMAN CAPITAL*

ABSTRACT We estimate a model of urban productivity in which the agglomeration effect of density is enhanced by a metropolitan area's stock of human capital. Estimation accounts for potential biases due to the endogeneity of density and industrial composition effects. Using new information on output per worker for U.S. metropolitan areas along with a measure of density that accounts for the spatial distribution of population, we find that a doubling of density increases productivity by 2–4 percent. Consistent with theories of learning and knowledge spillovers in cities, we demonstrate that the elasticity of average labor productivity with respect to density increases with human capital. Metropolitan areas with a human capital stock one standard deviation below the mean realize no productivity gain, while doubling density in metropolitan areas with a human capital stock one standard deviation above the mean yields productivity benefits that are about twice the average. These patterns are particularly pronounced in industries where the exchange of information and sharing of ideas are important parts of the production process.     

Gender and environmental struggles: voices from Adivasi Garo community in Bangladesh

Based on an ethnographic field investigation conducted on the matrilineal–matrilocal Garo community of Bangladesh, this article provides a historical account of local environmental struggles to draw attention to the interconnections between gender, environment and sustainable resource management. From a feminist political ecology perspective, the article argues that interacting with traditional culture, forest ecology and changing processes of centric resource governance, gender remains a salient variable in environmental issues. Local contexts of gender dynamics help configuring local people's mode of participation in environmental struggles as well as being the consequence of those struggles. Findings suggest that Garo women and men have sustained gender specific roles and interests through their struggles to ensure control over forest lands and tree resources. Furthermore, they have developed a class-based relationship with forest ecology which must be acknowledged in forest policies.     

Social decision-making driven by artistic explore–exploit tension

We studied social decision-making in the rule-based improvisational dance There Might Be Others, where dancers make in-the-moment compositional choices. Rehearsals provided a natural test-bed with communication restricted to non-verbal cues. We observed a key artistic explore–exploit tension in which the dancers switched between exploitation of existing artistic opportunities and riskier exploration of new ones. We investigated how the rules influenced the dynamics using rehearsals together with a model generalized from evolutionary dynamics. We tuned the rules to heighten the tension and modelled nonlinear fitness and feedback dynamics for mutation rate to capture the observed temporal phasing of the dancers' exploration-versus-exploitation. Using bifurcation analysis, we identified key controls of the tension and showed how they could shape the decision-making dynamics of the model much like turning a ‘dial’ in the instructions to the dancers could shape the dance. The investigation became an integral part of the development of the dance.     

Diaconiae,xenodochia, hospitalia and monasteries: ‘social security’ and the meaning of monasticism in early medieval Rome

The first section of this article examines the various types of charitable institutions operative in Rome between the seventh and the ninth centuries, in the light of what available textual and comparative evidence reveals about their respective functions. It is then suggested that these centres of assistance were staffed by resident monastic communities, an arrangement which accounts well for their many apparent similarities; which may help to explain the disappearance of the most commonly attested types (xenodochia and diaconiae) over the course of the ninth century; and which opens a window onto an alternative conception of monastic practice hitherto under‐represented in the scholarly tradition.
