Environmental Engineering (What is noise pollution)
Any unwanted sound that penetrates the environment is considered noise pollution, which comes from sources like street traffic, construction, airplanes, and consumer products. The normal tolerance level for noise is 80dB, with sounds above or below being pollution. Noise pollution can damage hair cells in the ear and lead to irreversible hearing loss over time. It also increases blood pressure and interferes with animal behaviors. Governments have established laws to regulate industrial, commercial, and residential noise levels as well as limit sounds during night hours to reduce noise pollution. Individual actions like observing car-free days and creating awareness can help address the issue.
Noise Pollution
Noise Pollution is defined as any undesirable human or machine created noise which disturbs human or animal activity or balance. It is measured in decibels (dB) which is a logarithmic ratio of sound pressures. Prolonged exposure to loud noise can cause permanent hearing loss, annoyance, stress, and disrupted sleep and human performance. Noise pollution affects animals through hearing loss, physiological stress, and disruption of behavior and ecosystems. Plants are also impacted through reduced growth. Control measures include reducing noise at the source through improved machinery and mufflers, zoning of industrial areas away from homes, sound insulation of buildings, use of ear protection, legislative bans on loud noises, and planting trees.

Each ashrama has specific duties and goals to help individuals progress spiritually on their journey towards moksha (liberation). The ashrama system aims to regulate social life and organize both individuals and society according to the guiding principles of dharma.

The document discusses the principles of sustainable development, noting that current models of development degrade the environment, do not meet the needs of future generations, and often do not benefit the most vulnerable in society. Sustainable development requires reconciling development and environmental protection, ensuring that growth benefits all sections of society, and empowering women and weaker sections through comprehensive development that includes capability building and preserving cultural roots.
Sustainable development (Sociology)
The document discusses sustainable development and the problems with unsustainable development. Unsustainable development leads to environmental degradation through activities like large-scale deforestation, pollution from toxic waste and industries, and excessive resource extraction. Sustainable development requires efficient use of natural resources, environmental education, population control, waste reduction, and protecting the environment while also pursuing economic growth. It outlines various measures like reducing consumption, supporting renewable energy and reforestation to work towards sustainable development goals.
Strategies for environment protection (Sociology)
Strategies for environment protection include educating oneself and others about protecting nature from destruction through awareness programs, discussions, and audiovisual materials. Student exhibitions and environment education in schools and colleges aim to help understand environment problems. Motivating different groups like slum dwellers, city elite, and the public against harmful policies involves organizing citizen groups, women, and people's participation through protest marches and utilizing media and voluntary organizations for campaigns.
Sociology and law unit 1 (Sociology)
This document discusses the history and development of sociology. It began as philosophical analyses of social life and studies of family and customs. It evolved into a scientific discipline between the 15th-18th centuries with thinkers like Hobbes, Locke and Rousseau. Sociology was formally established as a science in the late 19th century at universities in the United States, France and United Kingdom. It spread to universities in India in the early 20th century. Sociology is characterized as a scientific, empirical, and general study of society and social phenomena.
Socialisation (Sociology)
Socialization is the process by which individuals learn norms and customs to conform to society. It occurs through various stages across one's lifetime as they learn new social roles and ways of thinking. The key agents of socialization include family, school, peer groups, and other social institutions which help induct individuals into culture through imitation, suggestion, identification, and language. Theories of socialization explore how individuals develop a sense of self and identity through perceiving themselves and internalizing social norms.
Social system (Sociology)
A social system is composed of a plurality of individuals interacting according to shared cultural norms and meanings. It functions as an orderly arrangement of patterned relationships and interactions among its parts. Key elements of a social system include beliefs, sentiments, goals, norms, ranks, statuses, roles, power, sanctions, and facilities. A social system works to solve functional problems like pattern maintenance, tension management, adaptation, goal attainment, and integration. It is influenced by cultural factors and structured interactions that bind its parts into a unified whole.
Social structure (Sociology)
Social structure is defined as the stable interrelationships and patterns of organization among human beings in a society. It consists of institutions that establish roles and statuses for individuals. A social structure includes a normative system that defines values and behaviors, a position system that assigns roles, and a sanction system that enforces norms. A social structure is dynamic and can change over time as it works to integrate individuals and anticipate future roles through a system of cultural patterns, subgroups, and both formal and informal relationships.
Social stratifiacation (Sociology)
The document discusses social stratification, which refers to the division of a society into socioeconomic strata. Social stratification results in inequality, with some groups seen as superior or inferior to others. It is a universal social phenomenon that is ancient in origin. Some common bases for social stratification include age, sex, wealth/property, and caste or class. The document provides examples of historical forms of social stratification like slavery, the estate system in medieval Europe, and the varna system in ancient India, which divided society into four hierarchical categories based on skin color and occupation. While the varna system aimed to motivate occupational roles, it ultimately led to a rigid caste system and further social inequality.
Social organisation (Sociology)
Social organisation involves the arrangement of interrelated parts, like members of a family, church, or workplace, into a coordinated whole with defined goals. It is characterized by members accepting roles and statuses to achieve common goals through conforming to norms that are enforced by a sanction system of rewards and punishments. This coordination allows specialized parts to function meaningfully together as a system towards a unified purpose.
Social mobility (Sociology)
Social mobility refers to changes in social status or position, such as upward, downward, or parallel movements. It is related to changes in a person's social status and is a characteristic of industrial or urban societies. There are different types of social mobility including horizontal (movement within the same social level), vertical (movement up or down levels), and inter-generational occupational mobility (a change or adoption of occupations between generations). Sources of vertical social mobility include institutions like the army, religious groups, schools, politics, businesses, and families.
Social differentiations (Sociology)
The document discusses social differentiation and stratification. It explains that social differentiation refers to natural divisions in society based on factors like possessions, qualities and performance, without hierarchical rankings. Social stratification, on the other hand, refers to man-made divisions in society that establish rankings as higher or lower and consider concepts of purity and pollution, though these are less significant today. The document also outlines the scope and importance of sociology in understanding social phenomena, institutions, relationships and problems to reform society.
