This book provides an accessible introduction to causal inference and data analysis with R, specifically for a public policy audience. It aims to demystify these topics by presenting them through practical policy examples from a range of disciplines. It provides a hands-on approach to working with data in R using the popular tidyverse package. High quality R packages for specific causal inference techniques like ggdag, Matching, rdrobust, dosearch etc. are used in the book. The book is in two parts. The first part begins with a detailed narrative about John Snow’s heroic investigations into the cause of cholera. The chapters that follow cover basic elements of R, regression, and an introduction to causality using the potential outcomes framework and causal graphs. The second part covers specific causal inference methods, including experiments, matching, panel data, difference-in-differences, regression discontinuity design, instrumental variables and meta-analysis, with the help of empirical case studies of policy issues. The book adopts a layered approach that makes it accessible and intuitive, using helpful concepts, applications, simulation, and data graphs. Many public policy questions are inherently causal, such as the effect of a policy on a particular outcome. Hence, the book would not only be of interest to students in public policy and executive education, but also to anyone interested in analysing data for application to public policy.
“An absorbing exploration of one man’s life” —as an orphan, refugee, shopkeeper, and grandfather—through a century of upheaval in India (Library Journal). Born in colonial India into a despised caste of former tree climbers, Ayya lost his mother as a child and came of age in a small town in lowland Burma. Forced to flee at the outbreak of World War II, he made a treacherous 1,700-mile journey by foot, boat, bullock cart, and rail back to southern India. Becoming a successful fruit merchant, Ayya educated and eventually settled many of his descendants in the United States. Luck, nerve, subterfuge, and sorrow all have their place along the precarious route of his advancement. Emerging out of tales told to his American grandson, Ayya’s Accounts embodies a simple faith—that the story of a place as large and complex as modern India can be told through the life of a single individual. “At once a mesmerizing memoir of an ordinary man’s life and an anthropologist’s revealing examination of the astounding changes experienced by persons and families . . . impossible to put down.” —South Asia “No one deemed a superhero by the movies has had a more interesting life with such extraordinary sweep.” —Scott Simon, NPR Weekend Edition

Due to the prohibitive cost of synthetic pesticides and the problems of environmental pollution caused by continuous use of these chemicals, there is a renewed interest in the use of botanicals for crop protection. Agricultural entomologists, nematologists, and pathologists the world over are now actively engaged in research into the use of plants to fight agricultural pests and diseases, and to reduce the losses caused by them. Botanical Pesticides in Agriculture reviews the research on botanical pesticides used to combat losses due to pests of agricultural importance, with special attention focused on the use of higher plants. This book will serve as the baseline reference work for future research, and many of the botanicals discussed, such as neem, bael, begonia, pyrethrum, tobacco, karanj, and mahuwa, may become integral parts of pest control programs currently being developed. It is believed that botanical pesticides will minimize the undesirable side effects of synthetic pesticides and help preserve the environment for future generations.
How do people come to live as they ought to live? Crooked Stalks seeks an answer to this enduring question in diverse practices of cultivation: in the moral horizons of development intervention, in the forms of virtue through which people may work upon their own desires, deeds, and habits, and in the material labors that turn inhabited worlds into environments for both moral and natural growth. Focusing on the colonial subjection and contemporary condition of the Piramalai Kallar caste—classified, condemned, and policed for decades as a “criminal tribe”—Anand Pandian argues that the work of cultivation in all of these senses has been essential to the pursuit of modernity in south India. Colonial engagements with the Kallars in the early twentieth century relied heavily upon agrarian strategies of moral reform, an approach that echoed longstanding imaginations of the rural cultivator as a morally cultivated being in Tamil literary, moral, and religious tradition. These intertwined histories profoundly shape how people of the community struggle with themselves as ethical subjects today. In vivid, inventive, and engaging prose, Pandian weaves together ethnographic encounters, archival investigations, and elements drawn from Tamil poetry, prose, and popular cinema. Tacking deftly between ploughed soils and plundered orchards, schoolroom lessons and stationhouse registers, household hearths and riverine dams, he reveals moral life in the postcolonial present as a palimpsest of traces inherited from multiple pasts. Pursuing these legacies through the fragmentary play of desire, dream, slander, and counsel, Pandian calls attention not only to the moral potential of ordinary existence, but also to the inescapable force of accident, chance, and failure in the making of ethical lives. Rarely are the moral coordinates of modern power sketched with such intimacy and delicacy.

Cloud computing offers subscription-based on-demand services, and it has emerged as the backbone of the computing industry. It has enabled us to share resources among multiple users through virtualization, which creates a virtual instance of a computer system running in an abstracted hardware layer. Unlike early distributed computing models, it offers virtually limitless computing resources through its large scale cloud data centers. It has gained wide popularity over the past few years, with an ever-increasing infrastructure, a number of users, and the amount of hosted data. The large and complex workloads hosted on these data centers introduce many challenges, including resource utilization, power consumption, scalability, and operational cost. Therefore, an effective resource management scheme is essential to achieve operational efficiency with improved elasticity. Machine learning enabled solutions are the best fit to address these issues as they can analyze and learn from the data. Moreover, it brings automation to the solutions, which is an essential factor in dealing with large distributed systems in the cloud paradigm.

MAHAD has an iconic place in Dalit universe. Associated with legendary personality of Dr Ambedkar, the struggle of Dalits at Mahad for asserting their rights to access the public tank, the Chavadar tank, arguably ranks among the first civil rights struggles in history. Unfortunately, it remained largely confined to folklore; its detailed account still remaining fragmented and in mostly Marathi. This book provides a comprehensive account, using many sources including the archival materials, of the two conferences in Mahad in 1927 that marks the beginning of the Dalit movement under Babasaheb Ambedkar to a wider readership in English. It tries to frame it within its historical context which will help people comprehend its historical significance. It also seeks to draw certain lessons for the future course of the Dalit movement. The book additionally contains the original account of Comrade R. B. MORE, the organizer of the first conference at Mahad.
While the caste system has been formally abolished under the Indian Constitution, according to official statistics, every eighteen minutes a crime is committed in India on a dalit-untouchable. The Persistence of Caste uses the shocking case of Khairlanji, the brutal murder of four members of a dalit family in 2006, to explode the myth that caste no longer matters. In this exposé, Anand Teltumbde locates the crime within the political economy of post-Independence India and across the global Indian diaspora. This book demonstrates how caste has shown amazing resilience - surviving feudalism, capitalist industrialization and a republican constitution - to still be alive and well today, despite all denial, under neoliberal globalization. This insightful new analysis not only provides a fascinating introduction to the issue of caste in a globalized world, but also sharpens our understanding of caste dynamics as they really exist.
