Evaluating Simulant Materials for Understanding Cranial Backspatter from a Ballistic Projectile

In cranial wounds resulting from a gunshot, the study of backspatter patterns can provide information about the actual incidents by linking material to surrounding objects. This study investigates the physics of backspatter from a high‐speed projectile impact and evaluates a range of simulant materials using impact tests. Next, we evaluate a mesh‐free method called smoothed particle hydrodynamics (SPH) to model the splashing mechanism during backspatter. The study has shown that a projectile impact causes fragmentation at the impact site, while transferring momentum to fragmented particles. The particles travel along the path of least resistance, leading to partial material movement in the reverse direction of the projectile motion causing backspatter. Medium‐density fiberboard is a better simulant for a human skull than polycarbonate, and lorica leather is a better simulant for a human skin than natural rubber. SPH is an effective numerical method for modeling the high‐speed impact fracture and fragmentations.     

Critical Observations on Neo-liberalism and India’s New Economic Policy

Abstract

Neo-liberalism is capitalism without leftist illusions (i.e. illusions that there can be such a thing as humane capitalism on a long-term basis). The article makes a series of critical comments on India’s neo-liberalism expressed in the form of the so-called New Economic Policy. It argues, New Economic Policy is more than a governmental policy. It is rather a policy of capital, mediated and implemented by the state. Neo-liberalism is a social-spatial project. Neo-liberalism in rural areas (agrarian neo-liberalism) is particularly ruthless. Neo-liberalism is implemented through, and entails, the transformation of space, and thus produces enormous spatial unevenness. Neo-liberalism is also a part of the imperialist project. Given New Economic Policy’s adverse impacts, it has inspired massive resistance from below. Interestingly, in spite of offering some opposition, the left has been, overall, a conduit through which New Economic Policy has worked. The article shows how a critical discussion on neo-liberalism has implications for understanding macro-structural changes in societies such as that of India, which have suffered not only from economic backwardness but also incomplete revolutions. A dialectical view of neo-liberalism and the New Economic Policy connects them both to the democratic and agrarian questions, the national question, and the question of socialism itself.     

The Mughals, merchants and the European Companies in the 17th century Surat

This paper deals with the port administration of Surat. It looks into the ways in which the port administration dealt with the European Companies and tried to control them. An analysis of the records of the period enables us to see how the European trading Companies responded to the rules and regulations laid by the Mughal authorities. The issues concerning the mint and monetary regulations will also be reviewed. The bullion importation by the Companies and their effort to procure ready money for commercial transactions will be dealt with. What role did the embassies and representations to the Mughal court play in the procurement of trading concessions? Did Indian merchants enjoy immunities from customs and tolls compared to European Companies by the Mughal state? An attempt has been made to answer these questions.     

A View of Public Action as Collective Action: Evidence From an Indian Village

A theory of public action will be a sociological one, for it can explain the activities of different individual stakeholders who are both driven by varied motives and interests and are required to come together for achieving some avowedly public objective. On the basis of a review of scholarly literature and three case studies of public action (based on ethnographic fieldwork) in an Indian village, this study observes that public action is far more complex than celebrated problems of collective action. In public action we want collective action to happen and deliver optimum outputs for target publics. But this should at the same time offer gains, rewards, and outcomes of different kinds to different stakeholders. This discussion aims to outline the scope and possible types of public action. Such a discussion has important implications, for policy as public action should be designed adequately as collective action with differential rewards in place for participants.
