The subtitle says it all: how and why Bollywood found it worthwhile to explore the reality of the millennial women who are thriving in India - small part of the demographics but very influential. Advertising discovered women as The Hindi film Heroine is a brand and brand ambassador. The market met contemporary women who are independent, with freer attitudes to relationships, including pre-marital sex, Rom coms of the new millennium reflect this new-found freedom, defying patriarchy that still defines our society. Globalisation is culturally irreversible. From the 1990s onwards, Bollywood has responded to globalisation with fear of loss of identity and desire to integrate with global trends. It results in popular cinema becoming glocal. Bollywood celebrates nonconformists, subversives woman as the hero, stories in their own way unequivocally said No means No. Most daringly. Iconic characters like Choti Bahu, Paro and Chandramukhi transformed into today’s women with the power to change their lives. This happened with the energy infused into the mainstream by indie filmmakers with vision and the will to tell stories in their own way.
Environmental law and policy in India affects all sections of society. Those most deeply affected by it are the poor. They are the first victims of poor sanitation, polluted air, and contaminated water. Since the 1970s, efforts to protect environmental quality have met with limited success, posing enduring challenges for policy designers and decision-makers entrusted with protecting and preserving natural resources. This edition of Environmental Law and Policy retains the familiar analytical structure of the second edition and includes all major developments since then. It focuses on Indian environmental law, policies, problems, and needs with the comprehensiveness of an American law case book, compiles all the leading cases in environmental law in India with concise extracts of landmark judgments and policy documents, and provides discussions on projects which could potentially degrade the environment. This volume also covers air and water pollution, forests, wildlife, noise pollution, common property resources and tribal communities, environmental impact assessment, coastal regulations, large projects, urban problems, the National Green Tribunal, hazardous substances, transnational environmental policies, and international environment law. It is interlaced with notes, comments, and questions intended to encourage critical thinking amongst lawyers and law students.
This Handbook on Preterm Prelabor Rupture of Membranes in a Low Resource Setting is very important from the Obstetrician s point of view. It concerns one of the 5 Ps, i.e. postpartum hemorrhage, preterm labor, pregnancy hypertension, PROM and parturition problems which cause most of the maternal and perinatal mortality and morbidity not only in the AOFOG federation but also in the whole world. This handbook looks at the disease from an Asian perspective. Most of the literature on the topic have been from a Western view and it isrefreshing to look at it from another angle. This book addresses a complication of pregnancy, which tests the skill of the obstetrician as far as decision-making is concerned. The extent of neonatal services available largely determines the course of management that eventually choose in such a patient. In a low resource setting, where obstetric and neonatal services are not at their best decision making, the management is more difficult. This book will provide useful and comprehensive guidance to the frontline workers in Obstetrics and Gynecology to help them to manage this important and challenging condition.

Recently, South Asian writers such as Salman Rushdie, Michael Ondaatje, Rohinton Mistry, Bharati Mukherjee, Jhumpa Lahiri, and Monica Ali have been dominating the world’s literary scene, winning prestigious prizes, and appearing on numerous bestseller lists, and being hailed by critics and readers worldwide. Yet never before has their work appeared together in an anthology. Now, for the first time, the internationally heralded writer Shyam Selvadurai has collected the very best of South Asian short fiction in Story-Wallah!, a remarkable anthology showcasing 26 beautifully written stories whose memorable characters will remain with the reader long after they have closed the pages of this book. A "wallah" is a hawker or merchant. In Story-Wallah! some of the world’s best fiction writers hawk their wares from different parts of the South Asian diaspora - Canada, the United States, Britain, Guyana, Trinidad, Malaysia, Tanzania, Fiji - creating a virtual map of the world with their tales. There is an eclectic quality to the way the stories jostle up against each other: life on a sugar plantation in Trinidad next to the story of a childhood in rural 1930’s Australia. A Christmas in Fiji next to the attempts by an Indian family in South Africa to arrange a marriage for their rebellious daughter. A honeymoon in lush Sri Lanka next to the trials of a Bangladeshi refugee in England. The result is a marvelous cacophony, like early morning at a South Asian bazaar. Story-Wallah! is essential reading for anyone with an interest in South Asian writers and the dynamic, important tales they have to tell.
