Originally published in 1974, the conclusions of the book are based on intensive field-work during 1963-66 in a village in south-east Rajasthan, India. Although the marriages of 158 boys and 163 girls were studied, the relevance of the conclusions drawn extends far beyond the village and its region since it reveals the changing themes and values in Indian society at the time. The perceptive analysis of rites and ceremonies of marriage further illuminates the central problem of the book - how the themes of the Dharmasastras are interpreted and acted upon in village life and what kinds of reinforcements and incentives to change they provide to the various units of social structure. The author contends that the series of marriage rites manifest the continuity of tradition, a ritual epitomisation of caste interdependence and means of systematic social advancement. At the time ritual idioms and patterns of social exchange were beginning to change, more often in observance than in content. Traditional sources of status aggrandisement continued to provide new pathways to the forces of modernisation and unveil several clues to the innovative strategies of change. This scholarly study filled the need for a realistic appraisal of the relationship between marriage practices, religious values and the changing social structure.

Data analytics is proving to be an ally for epidemiologists as they join forces with data scientists to address the scale of crises. Analytics examined from many sources can derive insights and be used to study and fight global outbreaks. Pandemic analytics is a modern way to combat a problem as old as humanity itself: the proliferation of disease. Machine Learning and Data Analytics for Predicting, Managing, and Monitoring Disease explores different types of data and discusses how to prepare data for analysis, perform simple statistical analyses, create meaningful data visualizations, predict future trends from data, and more by applying cutting edge technology such as machine learning and data analytics in the wake of the COVID-19 pandemic. Covering a range of topics such as mental health analytics during COVID-19, data analysis and machine learning using Python, and statistical model development and deployment, it is ideal for researchers, academicians, data scientists, technologists, data analysts, diagnosticians, healthcare professionals, computer scientists, and students.

Roughly 30 percent of the solar radiation directed toward the earth is reflected directly back into outer space. The remaining 70 percent is absorbed by earth and re-emitted outward as long-wave -- or infra-red -- radiation. While transparent to incoming solar radiation, certain gases--notably carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons -- absorb, or " trap, " this outgoing infra-red radiation near the earth's surface, producing an increase in temperature. This is the so-called greenhouse effect. The greater the concentration of these greenhouse gases, the more pronounced will be the effect. Despite uncertainties, the scientific consensus recorded at Villach, Austria, in 1985 was that " the understanding of the greenhouse question is sufficiently developed that scientists and policy-makers should begin an active collaboration to explore the effectiveness of alternatives and adjustments." The recent scientific assessment of climate change, conducted under the auspices of the UN Intergovernmental Panel on Climate Change, has only strengthened the view that a concerted multilateral response is called for.
