Social researchSocial research is a research conducted by social scientists following a systematic plan. Social research methodologies can be classified as quantitative and qualitative. Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analysis of many cases (or across intentionally designed treatments in an experiment) to create valid and reliable general claims. Related to quantity.
Car classificationGovernments and private organizations have developed car classification schemes that are used for various purposes including regulation, description, and categorization of cars. The International Standard ISO 3833-1977 Road vehicles – Types – Terms and definitions also defines terms for classifying cars. The following table summarises the commonly used terms of market segments and legal classifications. Microcar and Kei car Microcars and their Japanese equivalent— kei cars— are the smallest category of automobile.
Sleeping carThe sleeping car or sleeper (often wagon-lit) is a railway passenger car that can accommodate all passengers in beds of one kind or another, for the purpose of sleeping. George Pullman was the American innovator of the sleeper car. The first such cars saw sporadic use on American and English railways in the 1830s; they could be configured for coach seating during the day. Possibly the earliest example of a sleeping car (or bed carriage, as it was then called) was on the London & Birmingham and Grand Junction Railways between London and Lancashire, England.
Passenger railroad carA passenger railroad car or passenger car (American English), also called a passenger carriage, passenger coach (British English and International Union of Railways), or passenger bogie (Indian English) is a railroad car that is designed to carry passengers. The term passenger car can also be associated with a sleeping car, a baggage car, a dining car, railway post office and prisoner transport cars. The first passenger cars were built in the early 1800s with the advent of the first railroads, and were small and little more than converted freight cars.
Urban sprawlUrban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development.
Climate change mitigationClimate change mitigation is action to limit climate change by reducing emissions of greenhouse gases or removing those gases from the atmosphere. The recent rise in global average temperature is mostly due to emissions from burning fossil fuels such as coal, oil, and natural gas. Mitigation can reduce emissions by transitioning to sustainable energy sources, conserving energy, and increasing efficiency. It is possible to remove carbon dioxide () from the atmosphere by enlarging forests, restoring wetlands and using other natural and technical processes.
