Participation and Power: Poor People's Engagement with India's Employment Assurance Scheme

‘Participation’ has become an essential part of good developmental practice for Southern governments, NGOs and international agencies alike. In this article we reflect critically on this shift by investigating how a ‘participatory’ development programme — India's Employment Assurance Scheme (EAS) — intersects with poor people's existing social networks. By placing the formalized process of participation in the EAS within the context of these varied and uneven village–level relationships, we raise a number of important issues for participatory development practice. We note the importance of local power brokers and the heterogeneity of ‘grassroots’ (dis)empowerment, and question ideas of power reversals used within the participatory development literature.     

Comparative microstructural and elemental analysis of iron artefacts from Kaveri valley archaeological sites

Iron has been one of the most critical technotraditions that had lasting impact on social formation throughout the Iron Age and historical period. Iron was used in warfare and subsistence economy. Our knowledge on ancient iron smelting and working have generally been derived from ethnography and ethnohistory, which is by all means, time, region, and raw material specific. Scientific analyses of ancient iron have contributed in understanding this heritage to a respectable extent, yet a comprehensive knowledge about the evolution of iron making through time and space in India eludes us. In this work, a comparative study of iron artefacts from two Iron Age/Megalithic-Early Historic sites of Tamil Nadu, south India, that is, Mangadu (burial site) and Ambal (habitation-cum-burial site) is carried out to understand the iron thermal-processing capabilities. The retrieved artefacts were examined using X-ray fluorescence (XRF) for elemental composition. The imaging of the artefacts was done using Scanning Electron Microscopy (SEM), Electron Backscatter Diffraction (EBSD), and Optical Microscopy (OM). In addition, phase identification was performed using X-ray diffraction (XRD) and Energy Dispersive X-ray Spectroscopy (EDS). Combination of these analyses illustrates that inhabitants of Mangadu and Ambal were aware of the iron alloy manufacturing/processing techniques such as forging and hammering.     

Probabilistic Seismic Hazard Model of West Bengal,India

We deliver a next-generation Probabilistic Seismic Hazard model of West Bengal based on improved seismogenic source characterization considering both the Layered Polygonal sources & Tectonic sources in the hypocentral depth range of 0–25 km & 25–70 km, seismic local-specific site condition, and adaption of appropriate region specific ground motion prediction equations in a logic tree framework. The surface consistent Probabilistic seismic hazard distribution in terms of Peak Ground Acceleration (PGA) & 5% damped Pseudo Spectral Acceleration (PSA) at different time periods for 10% probability of exceedance in 50 years have been generated and the design response spectra computed.
