Public utilities in the context of "State ownership"

A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in a world of intensifying globalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, climate change, and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant harmful effects, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

Charles Evans Hughes (April 11, 1862 – August 27, 1948) was an American politician, academic, and jurist who served as the 11th chief justice of the United States from 1930 to 1941. A member of the Republican Party, he previously was the 36th governor of New York (1907–1910), an associate justice of the Supreme Court (1910–1916), and 44th U.S. secretary of state (1921–1925). He was the Republican nominee in the 1916 presidential election, narrowly losing to incumbent president Woodrow Wilson.

Born to a Welsh immigrant preacher and his wife in Glens Falls, New York, Hughes graduated from Brown University and Columbia Law School and practiced law in New York City. After working in private practice for several years, in 1905 he led successful state investigations into public utilities and the life insurance industry. He won election as the governor of New York in 1906, and implemented several progressive reforms. In 1910, President William Howard Taft appointed Hughes as an associate justice of the Supreme Court of the United States. During his tenure on the Supreme Court, Hughes often joined Associate Justice Oliver Wendell Holmes Jr. in voting to uphold state and federal regulations.

Radiolocation, also known as radiolocating or radiopositioning, is the process of finding the location of something through the use of radio waves. It generally refers to passive, particularly radar—as well as detecting buried cables, water mains, and other public utilities. It is similar to radionavigation in which one actively seeks its own position; both are types of radiodetermination. Radiolocation is also used in real-time locating systems (RTLS) for tracking valuable assets.

In Marxist-Leninist theory, the commanding heights of the economy are certain strategically important economic sectors. Some examples of industries considered to be part of the commanding heights include public utilities, natural resources, and sectors relating to both foreign trade and domestic trade.
