Works Progress Administration
–
In a much smaller but more famous project, Federal Project Number One, the WPA employed musicians, artists, writers, actors and directors in large arts, drama, media, and literacy projects. Almost every community in the United States had a new park, the WPAs initial appropriation in 1935 was for $4.9 billion. Headed by Harry Hopkins, the WPA provided jobs and income to the unemployed during the Great Depression in the United States. At its peak in 1938, it provided jobs for three million unemployed men and women, as well as youth in a separate division, the National Youth Administration. Between 1935 and 1943, when the agency was disbanded, the WPA employed 8.5 million people, most people who needed a job were eligible for employment in some capacity. Hourly wages were set to the prevailing wages in each area. The stated goal of building programs was to end the depression or, at least, alleviate its worst effects. Millions of people needed subsistence incomes, Work relief was preferred over public assistance because it maintained self-respect, reinforced the work ethic, and kept skills sharp. The WPA was a program that operated its own projects in cooperation with state and local governments. Usually the local sponsor provided land and often trucks and supplies, WPA sometimes took over state and local relief programs that had originated in the Reconstruction Finance Corporation or Federal Emergency Relief Administration programs. It was liquidated on June 30,1943, as a result of low unemployment due to the shortage of World War II. The WPA had provided millions of Americans with jobs for eight years, on May 6,1935, FDR issued Executive Order 7034, establishing the Works Progress Administration. The WPA superseded the work of the Federal Emergency Relief Administration, direct relief assistance was permanently replaced by a national work relief program—a major public works program directed by the WPA. The WPA was largely shaped by Harry Hopkins, supervisor of the Federal Emergency Relief Administration, both Roosevelt and Hopkins believed that the route to economic recovery and the lessened importance of the dole would be in employment programs such as the WPA. The Division of Professional and Service Projects, which was responsible for projects including education programs, recreation programs. It was later named the Division of Community Service Programs and the Service Division, the Division of Investigation, which succeeded a comparable division at FERA and investigated fraud, misappropriation of funds and disloyalty. The Division of Statistics, also known as the Division of Social Research, the Project Control Division, which processed project applications. Other divisions including the Employment, Management, Safety, Supply, the goal of the WPA was to employ most of the unemployed people on relief until the economy recovered

Infrastructure
–
Infrastructure refers to the fundamental facilities and systems serving a country, city, or area, including the services and facilities necessary for its economy to function. The word was imported from French, where it means subgrade, the word is a combination of the Latin prefix infra, meaning below, and structure. The military use of the term achieved currency in the United States after the formation of NATO in the 1940s and this crisis discussion contributed to an increase in infrastructure asset management and maintenance planning in the US. Public-policy discussions have been hampered by lack of a definition for infrastructure. A1987 US National Research Council panel adopted the public works infrastructure. The OECD also classifies communications as a part of infrastructure, the American Society of Civil Engineers has not defined the term, though issuing a US Infrastructure Report Card every 2-4 years. Hard infrastructure refers to the physical networks necessary for the functioning of an industrial nation. The term critical infrastructure distinguishes those infrastructure elements that, if damaged or destroyed. Similarly, a booking system might be critical infrastructure for an airline. These elements of infrastructure are the focus of efforts in the aftermath of natural disasters. The term infrastructure may be confused with the following overlapping or related concepts, service connections to municipal service and public utility networks would also be considered land improvements, not infrastructure. The term public works includes government-owned and operated infrastructure as well as buildings, such as schools. Public works generally refers to physical assets needed to deliver public services, public services include both infrastructure and services generally provided by government. Infrastructure may be owned and managed by governments or by private companies, generally, most roads, major ports and airports, water distribution systems and sewage networks are publicly owned, whereas most energy and telecommunications networks are privately owned. Publicly owned infrastructure may be paid for taxes, tolls, or metered user fees. Major investment projects are financed by the issuance of long-term bonds. Government owned and operated infrastructure may be developed and operated in the sector or in public-private partnerships. As of 2008 in the United States for example, public spending on infrastructure has varied between 2. 3% and 3. 6% of GDP since 1950, many financial institutions invest in infrastructure

Government
–
A government is the system by which a state or community is controlled. In the case of this broad definition, government normally consists of legislators, administrators. Government is the means by which state policy is enforced, as well as the mechanism for determining the policy of the state. Forms of government, or forms of governance, refers to the set of political systems. Governments control the economy, social freedoms, and political systems and this usage is analogous to what is called an administration in American English. Finally, government is sometimes used in English as a synonym for governance. In addition to the political meanings, in grammar and theoretical linguistics

Community
–
A community is a small or large social unit who have something in common, such as norms, religion, values, or identity. Often - but not always - communities share a sense of place that is situated in a geographical area. Durable relations that extend beyond immediate genealogical ties also define a sense of community, people tend to define those social ties as important to their identity, practice, and roles in social institutions like family, home, work, government, society, or humanity, at large. The word community derives from the Old French comuneté, which comes from the Latin communitas community, human communities may share intent, belief, resources, preferences, needs, and risks in common, affecting the identity of the participants and their degree of cohesiveness. Community studies is an academic field drawing on both sociology and anthropology and the research methods of ethnography and participant observation in the study of community. In academic settings around the world, community studies is variously a sub-discipline of anthropology or sociology and it is often interdisciplinary and geared toward practical applications rather than purely theoretical perspectives. Community studies is sometimes combined with other fields, i. e. Urban and Community Studies, Health and Community Studies, or Family, while studies of the Internet are now widespread across academic disciplines, there is a growing collaboration among these investigations. On the research side, Internet studies intersects with studies of cyberculture, human–computer interaction, Urban sociologists contest the significance of place in shaping community. The anonymity and impersonal characterizing life in modern city spaces tend to be devoid of the collective connectedness associated with the idea of community”. The philosophy of science is the study of the logic and method of the social sciences, such as sociology, anthropology. Cultural anthropology is a branch of anthropology focused on the study of variation among humans. It is in contrast to social anthropology, which perceives cultural variation as a subset of the anthropological constant, a variety of methods are involved in cultural anthropological, including participant observation, interviews, and surveys. The term civilization later gave way to definitions given by V. Gordon Childe, with forming an umbrella term. Anthropologists have argued that culture is human nature, and that all people have a capacity to classify experiences, encode classifications symbolically, since humans acquire culture through the learning processes of enculturation and socialization, people living in different places or different circumstances develop different cultures. Anthropologists have also pointed out that through culture people can adapt to their environment in non-genetic ways, much of anthropological theory has originated in an appreciation of and interest in the tension between the local and the global. Colonialism and its processes increasingly brought European thinkers into direct or indirect contact with primitive others, the umbrella term socio-cultural anthropology draws upon both cultural and social anthropology traditions. In archaeological studies of communities the term community is used in two ways, paralleling usage in other areas. The first is a definition of community as a place where people used to live

City and town halls
–
In local government, a city hall, town hall, civic centre, a guildhall, a Rathaus, or a municipal building, is the chief administrative building of a city, town, or other municipality. It usually houses the city or town council, its associated departments and it also usually functions as the base of the mayor of a city, town, borough, or county / shire. By convention, until the mid 19th-century, a large open chamber formed an integral part of the building housing the council. The hall may be used for meetings and other significant events. This large chamber, the hall, has become synonymous with the whole building. The terms council chambers, municipal building or variants may be used locally in preference to town hall if no such large hall is present within the building, the local government may endeavor to use the town hall building to promote and enhance the quality of life of the community. In many cases, town halls serve not only as buildings for government functions and these may include art shows, stage performances, exhibits and festivals. Modern town halls or civic centres are designed with a great variety and flexibility of purpose in mind. As symbols of government, city and town halls have distinctive architecture. City hall buildings may also serve as icons that symbolize their cities. The term town hall may be a one, often applied without regard to whether the building serves or served a town or a city. This is generally the case in the United Kingdom, Australia, New Zealand, Hong Kong, english-speakers in some regions use the term city hall to designate the council offices of a municipality of city status. This is the case in North America, where a distinction is made between city halls and town halls, and is also the case with Brisbane City Hall in Australia. The great hall of the town-house or municipal building, now commonly applied to the whole building city hall. Conversely, cities that have subdivisions with their own councils may have borough halls, in Scotland, local government in larger cities operates from the City Chambers, otherwise the Town House. Elsewhere in English-speaking countries, other names are occasionally used, in London, the official headquarters of administration of the City of London retains its Anglo-Saxon name, the Guildhall, signifying a place where taxes were paid. In a small number of English cities the preferred term is Council House, this was also the case in Bristol until 2012, when the building was renamed City Hall. In Birmingham, there is a distinction between the Council House, the seat of government, and the Town Hall, a concert

School
–
A school is an institution designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of education, which is commonly compulsory. In these systems, students progress through a series of schools, the names for these schools vary by country but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught, is called a university college or university. In addition to these schools, students in a given country may also attend schools before. Kindergarten or pre-school provide some schooling to young children. University, vocational school, college or seminary may be available after secondary school, a school may also be dedicated to one particular field, such as a school of economics or a school of dance. Alternative schools may provide nontraditional curriculum and methods, there are also non-government schools, called private schools. Private schools may be required when the government does not supply adequate, Schools for adults include institutions of corporate training, military education and training and business schools. In homeschooling and online schools, teaching and learning take place outside of a school building. Schools are commonly organized in several different organizational models, including departmental, small learning communities, academies, integrated, and schools-within-a-school. The word school derives from Greek σχολή, originally meaning leisure and also that in which leisure is employed, the concept of grouping students together in a centralized location for learning has existed since Classical antiquity. Formal schools have existed at least since ancient Greece, ancient Rome ancient India, the Byzantine Empire had an established schooling system beginning at the primary level. According to Traditions and Encounters, the founding of the education system began in 425 AD. The sometimes efficient and often large government of the Empire meant that citizens were a must. Although Byzantium lost much of the grandeur of Roman culture and extravagance in the process of surviving, the Byzantine education system continued until the empires collapse in 1453 AD. Beginning in the 5th century CE monastic schools were established throughout Western Europe. Islam was another culture developed a school system in the modern sense of the word

Hospital
–
A hospital is a health care institution providing patient treatment with specialized medical and nursing staff and medical equipment. The best-known type of hospital is the hospital, which typically has an emergency department to treat urgent health problems ranging from fire. A district hospital typically is the health care facility in its region, with large numbers of beds for intensive care. Specialised hospitals can help reduce health care costs compared to general hospitals, a teaching hospital combines assistance to people with teaching to medical students and nurses. The medical facility smaller than a hospital is called a clinic. Hospitals have a range of departments and specialist units such as cardiology, some hospitals have outpatient departments and some have chronic treatment units. Common support units include a pharmacy, pathology, and radiology, Hospitals are usually funded by the public sector, by health organisations, by health insurance companies, or by charities, including direct charitable donations. Historically, hospitals were founded and funded by religious orders, or by charitable individuals. During the Middle Ages, hospitals served different functions from modern institutions, Middle Ages hospitals were almshouses for the poor, hostels for pilgrims, or hospital schools. The word hospital comes from the Latin hospes, signifying a stranger or foreigner, another noun derived from this, hospitium came to signify hospitality, that is the relation between guest and shelterer, hospitality, friendliness, and hospitable reception. By metonymy the Latin word then came to mean a guest-chamber, guests lodging, hospes is thus the root for the English words host hospitality, hospice, hostel and hotel. The German word Spital shares similar roots, the grammar of the word differs slightly depending on the dialect. Some patients go to a hospital just for diagnosis, treatment, or therapy and then leave without staying overnight, while others are admitted and stay overnight or for several days or weeks or months. Hospitals usually are distinguished from other types of facilities by their ability to admit and care for inpatients whilst the others. Larger cities may have several hospitals of varying sizes and facilities, some hospitals, especially in the United States and Canada, have their own ambulance service. A district hospital typically is the health care facility in its region, with large numbers of beds for intensive care. In California, district hospital refers specifically to a class of healthcare facility created shortly after World War II to address a shortage of beds in many local communities. Twenty-eight of Californias rural hospitals and 20 of its critical-access hospitals are District hospitals, Californias District hospitals are formed by local municipalities, have Boards that are individually elected by their local communities, and exist to serve local needs

Transport infrastructure
–
Transport or transportation is the movement of people, animals and goods from one location to another. Modes of transport include air, rail, road, water, cable, pipeline, the field can be divided into infrastructure, vehicles and operations. Transport is important because it enables trade between people, which is essential for the development of civilizations, terminals may be used both for interchange of passengers and cargo and for maintenance. Vehicles traveling on these networks may include automobiles, bicycles, buses, trains, trucks, people, helicopters, operations deal with the way the vehicles are operated, and the procedures set for this purpose including financing, legalities and policies. In the transport industry, operations and ownership of infrastructure can be public or private, depending on the country. Passenger transport may be public, where operators provide scheduled services, freight transport has become focused on containerization, although bulk transport is used for large volumes of durable items. Transport plays an important part in growth and globalization, but most types cause air pollution. While it is subsidized by governments, good planning of transport is essential to make traffic flow. A mode of transport is a solution that makes use of a type of vehicle, infrastructure. The transport of a person or of cargo may involve one mode or several of the modes, each mode has its own advantages and disadvantages, and will be chosen for a trip on the basis of cost, capability, and route. Human powered transport, a form of transportation, is the transport of people and/or goods using human muscle-power. Modern technology has allowed machines to enhance human power, human-powered vehicles have also been developed for difficult environments, such as snow and water, by watercraft rowing and skiing, even the air can be entered with human-powered aircraft. Animal-powered transport is the use of working animals for the movement of people, humans may ride some of the animals directly, use them as pack animals for carrying goods, or harness them, alone or in teams, to pull sleds or wheeled vehicles. A fixed-wing aircraft, commonly called airplane, is a craft where movement of the air in relation to the wings is used to generate lift. The term is used to distinguish this from rotary-wing aircraft, where the movement of the lift surfaces relative to the air generates lift, a gyroplane is both fixed-wing and rotary-wing. Fixed-wing aircraft range from small trainers and recreational aircraft to large airliners, two things necessary for aircraft are air flow over the wings for lift and an area for landing. The majority of aircraft also need an airport with the infrastructure to receive maintenance, restocking, refueling and for the loading and unloading of crew, cargo and passengers. While the vast majority of land and take off on land, some are capable of take off and landing on ice, snow

Road
–
Roads consist of one or two roadways, each with one or more lanes and any associated sidewalks and road verges. Roads that are available for use by the public may be referred to as parkways, avenues, freeways, interstates, highways, or primary, secondary, and tertiary local roads. In urban areas roads may diverge through a city or village and be named as streets, serving a function as urban space easement. Modern roads are normally smoothed, paved, or otherwise prepared to allow easy travel, historically many roads were simply recognizable routes without any formal construction or maintenance. In the United Kingdom there is ambiguity between the terms highway and road. The Highway code details rules for road users and this includes footpaths, bridleways and cycle tracks, and also road and driveways on private land and many car parks. Vehicle Excise Duty, a use tax, is payable on some vehicles used on the public road. The definition of a road depends on the definition of a highway, in the United States, laws distinguish between public roads, which are open to public use, and private roads, which are privately controlled. The assertion that the first pathways were the trails made by animals has not been universally accepted, others believe that some roads originated from following animal trails. The Icknield Way is given as an example of type of road origination. By about 10,000 BC, rough roads/pathways were used by human travelers, the worlds oldest known paved road was constructed in Egypt some time between 2600 and 2200 BC. Stone-paved streets are found in the city of Ur in the Middle East dating back to 4000 BC, corduroy roads are found dating to 4000 BC in Glastonbury, England. The Sweet Track, a timber causeway in England, is one of the oldest engineered roads discovered. Built in winter 3807 BC or spring 3806 BC, tree-ring dating enabled very precise dating and it was claimed to be the oldest road in the world until the 2009 discovery of a 6, 000-year-old trackway in Plumstead, London. Brick-paved streets were used in India as early as 3000 BC, in 500 BC, Darius I the Great started an extensive road system for Persia, including the Royal Road, which was one of the finest highways of its time. The road remained in use after Roman times, a hybrid of road transport and ship transport beginning in about 1740 is the horse-drawn boat in which the horse follows a cleared path along the river bank. From about 312 BC, the Roman Empire built straight strong stone Roman roads throughout Europe and North Africa, at its peak the Roman Empire was connected by 29 major roads moving out from Rome and covering 78,000 kilometers or 52,964 Roman miles of paved roads. In the 8th century AD, many roads were built throughout the Arab Empire, the most sophisticated roads were those in Baghdad, which were paved with tar

Railroad

Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks. It is also referred to as train transport. In contrast to road transport, where vehicles run on a flat surface. Tracks usually consist of rails, installed on ties and ballast, on which the rolling stock, usually fitted with metal wheels. Other variations are possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a transport system generally encounters lower frictional resistance than road vehicles, so passenger. The operation is carried out by a company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electric power from a railway system or produce their own power. Most tracks are accompanied by a signalling system, Railways are a safe land transport system when compared to other forms of transport. The oldest, man-hauled railways date back to the 6th century BC, with Periander, one of the Seven Sages of Greece, Rail transport blossomed after the British development of the steam locomotive as a viable source of power in the 19th centuries. With steam engines, one could construct mainline railways, which were a key component of the Industrial Revolution, also, railways reduced the costs of shipping, and allowed for fewer lost goods, compared with water transport, which faced occasional sinking of ships. The change from canals to railways allowed for markets in which prices varied very little from city to city. In the 1880s, electrified trains were introduced, and also the first tramways, starting during the 1940s, the non-electrified railways in most countries had their steam locomotives replaced by diesel-electric locomotives, with the process being almost complete by 2000. During the 1960s, electrified high-speed railway systems were introduced in Japan, other forms of guided ground transport outside the traditional railway definitions, such as monorail or maglev, have been tried but have seen limited use. The history of the growth, decline and restoration to use of transport can be divided up into several discrete periods defined by the principal means of motive power used. The earliest evidence of a railway was a 6-kilometre Diolkos wagonway, trucks pushed by slaves ran in grooves in limestone, which provided the track element. The Diolkos operated for over 600 years, Railways began reappearing in Europe after the Dark Ages. The earliest known record of a railway in Europe from this period is a window in the Minster of Freiburg im Breisgau in Germany

Bridge
–
A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose, the Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced back to Proto-Indo-European *bʰrēw-. The word for the game of the same name has a different origin. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support, some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. Dating to the Greek Bronze Age, it is one of the oldest arch bridges still in existence, several intact arched stone bridges from the Hellenistic era can be found in the Peloponnese. The greatest bridge builders of antiquity were the ancient Romans, the Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs. An example is the Alcántara Bridge, built over the river Tagus, the Romans also used cement, which reduced the variation of strength found in natural stone. One type of cement, called pozzolana, consisted of water, lime, sand, brick and mortar bridges were built after the Roman era, as the technology for cement was lost. In India, the Arthashastra treatise by Kautilya mentions the construction of dams, a Mauryan bridge near Girnar was surveyed by James Princep. The bridge was swept away during a flood, and later repaired by Puspagupta, the use of stronger bridges using plaited bamboo and iron chain was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India and this bridge is also historically significant as it is the worlds oldest open-spandrel stone segmental arch bridge. European segmental arch bridges date back to at least the Alconétar Bridge, rope bridges, a simple type of suspension bridge, were used by the Inca civilization in the Andes mountains of South America, just prior to European colonization in the 16th century. During the 18th century there were innovations in the design of timber bridges by Hans Ulrich Grubenmann, Johannes Grubenmann. The first book on bridge engineering was written by Hubert Gautier in 1716, a major breakthrough in bridge technology came with the erection of the Iron Bridge in Shropshire, England in 1779. It used cast iron for the first time as arches to cross the river Severn, with the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron does not have the tensile strength to support large loads. With the advent of steel, which has a tensile strength, much larger bridges were built. In 1927 welding pioneer Stefan Bryła designed the first welded bridge in the world

Pipeline transport
–
Pipeline transport is the transportation of goods or material through a pipe. The latest data, in 2014, gives a total of less than 2,175,000 miles of pipeline in 120 countries of the world. The United States had 65%, Russia had 8%, and Canada had 3%, Pipeline and Gas Journal’s worldwide survey figures indicate that 118,623 miles of pipelines are planned and under construction. Of these,88,976 miles represent projects in the planning, Liquids and gases are transported in pipelines and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels - such as oil, natural gas and biofuels - and other fluids including sewage, slurry, water, pneumatic tubes using compressed air can be used to transport solid capsules. Oil pipelines are made from steel or plastic tubes which are usually buried, the oil is moved through the pipelines by pump stations along the pipeline. Natural gas are lightly pressurised into liquids known as Natural Gas Liquids, Natural gas pipelines are constructed of carbon steel. Highly toxic ammonia is theoretically the most dangerous substance to be transported through long-distance pipelines, hydrogen pipeline transport is the transportation of hydrogen through a pipe. District heating or teleheating systems use a network of insulated pipes which transport heated water, pipelines conveying flammable or explosive material, such as natural gas or oil, pose special safety concerns and there have been various accidents. Pipelines can be the target of vandalism, sabotage, or even terrorist attacks, in war, pipelines are often the target of military attacks. It is uncertain when the first crude oil pipeline was built, pipelines are generally the most economical way to transport large quantities of oil, refined oil products or natural gas over land. Natural gas are lightly pressurized into liquids knows as Natural Gas Liquids, small NGL processing facilities can be located in oil fields so the butane and propane liquid under light pressure of 125 pounds per square inch, can be shipped by rail, truck or pipeline. Propane can be used as a fuel in oil fields to heat various facilities used by the oil drillers or equipment and trucks used in the oil patch. EG, Propane will convert from a gas to a liquid under pressure,100 psi, give or take depending on temperature. Pipelines and rail cars use about double that pressure to pump at 250 psi, the distance to ship propane to markets is much shorter, as thousands of natural-gas processing plants are located in or near oil fields. Compared to shipping by railroad, pipelines have lower cost per unit, pipelines are preferable to transportation by truck for a number of reasons. Employment on completed pipelines represents only 1% of that of the trucking industry and this allows the Bakken Basin and Three Forks oil producers to get higher negotiated prices for their oil because they will not be restricted to just one wholesale market in the US. The distance from the biggest oil patch in North Dakota, is Williston, North Dakota, only about 85 miles or 137 kilometers to the Canada–US border, mutual funds and joint ventures are big investors in new oil and gas pipelines

Canal
–
Canals and navigations are human-made channels for water conveyance, or to service water transport vehicles. In the vernacular, both are referred to as canals, and in most cases, the works will have a series of dams. These areas are referred to as water levels, often just called levels. In contrast, a canal cuts across a drainage divide atop a ridge, many canals have been built at elevations towering over valleys and others water ways crossing far below. Cities need a lot of water and many canals with sources of water at a higher level can deliver water to a destination where there is a lack of water. The Roman Empires Aqueducts were such water supply canals, a navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river, a vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal is a channel that cuts across a drainage divide, most commercially important canals of the first half of the 19th century were a little of each, using rivers in long stretches, and divide crossing canals in others. This is true for many canals still in use, there are two broad types of canal, Waterways, canals and navigations used for carrying vessels transporting goods and people. These can be subdivided into two kinds, Those connecting existing lakes, rivers, other canals or seas and oceans and those connected in a city network, such as the Canal Grande and others of Venice Italy, the gracht of Amsterdam, and the waterways of Bangkok. Aqueducts, water canals that are used for the conveyance and delivery of potable water for human consumption, municipal uses, hydro power canals. Historically canals were of importance to commerce and the development, growth. In 1855 the Lehigh Canal carried over 1.2 million tons of burning anthracite coal, by the 1930s the company which built. By the early 1880s, canals which had little ability to compete with rail transport, were off the map. In the next couple of decades, coal was diminished as the heating fuel of choice by oil. Later, after World War I when motor-trucks came into their own, Canals are built in one of three ways, or a combination of the three, depending on available water and available path, Human made streams A canal can be created where no stream presently exists. Either the body of the canal is dug or the sides of the canal are created by making dykes or levees by piling dirt, stone, the water for the canal must be provided from an external source, like streams or reservoirs. Where the new waterway must change elevation engineering works like locks, lifts or elevators are constructed to raise, examples include canals that connect valleys over a higher body of land, like Canal du Midi, Canal de Briare and the Panama Canal

Port
–
A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, Ports with deeper water are rarer, but can handle larger ships. Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, some ports have an important military role. One of the worlds oldest known artificial harbors is at Wadi al-Jarf on the Red Sea, along with the finding of harbor structures, ancient anchors have also been found. Guangzhou was an important port during the ancient times as far back as the Qin Dynasty, canopus was the principal port in Egypt for Greek trade before the foundation of Alexandria. Athens port of Piraeus was the base for the Athenian fleet, lothal is one of the most prominent cities of the ancient Indus valley civilisation, located in the Bhāl region of the modern state of Gujarāt and dating from 3700 BCE. Ostia Antica was the port of ancient Rome with Portus established by Claudius, Ports often have cargo-handling equipment, such as cranes and forklifts for use in loading ships, which may be provided by private interests or public bodies. Often, canneries or other processing facilities will be located nearby, some ports feature canals, which allow ships further movement inland. Access to intermodal transportation, such as railroads and highways, is critical to a port, so that passengers, Ports with international traffic have customs facilities. Harbor pilots and tugboats may maneuver large ships in tight quarters when near docks, the terms port and seaport are used for different types of port facilities that handle ocean-going vessels, and river port is used for river traffic, such as barges and other shallow-draft vessels. An inland port is a port on a lake, river, or canal with access to a sea or ocean. An example of this is the St. Lawrence Seaway which allows ships to travel from the Atlantic Ocean several thousand kilometers inland to Great Lakes ports like Duluth-Superior, a fishing port is a port or harbor for landing and distributing fish. It may be a facility, but it is usually commercial. A fishing port is the port that depends on an ocean product. In recent decades, regulations to save fishing stock may limit the use of a fishing port, a dry port is an inland intermodal terminal directly connected by road or rail to a seaport and operating as a centre for the transshipment of sea cargo to inland destinations. A warm-water port is one where the water does not freeze in wintertime, because they are available year-round, warm-water ports can be of great geopolitical or economic interest. A seaport is further categorized as a port or a cargo port. Additionally, cruise ports are known as a home port or a port of call

Airport
–
An airport is an aerodrome with facilities for flights to take off and land. Airports often have facilities to store and maintain aircraft, and a control tower, larger airports may have fixed-base operator services, airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. An airport with a helipad for rotorcraft but no runway is called a heliport, an airport for use by seaplanes and amphibious aircraft is called a seaplane base. Such a base typically includes a stretch of water for takeoffs and landings. An international airport has facilities for customs and passport control. In warfare, airports can become the focus of fighting, for example the Battle of Tripoli Airport or the Battle for Donetsk Airport. An airport primarily for use is called an airbase or air station. Most of the airports are owned by local, regional. Airports are divided into landside and airside, landside includes parking lots, public transport railway stations and access roads. Airside includes all areas accessible to aircraft, including runways, taxiways, passage between landside and airside is tightly controlled at all airports. To access airside, one must go through Security, and if applicable and this applies to everyone, including staff. Most major airports provide commercial outlets for products and services, Airports may also contain premium and VIP services. The premium and VIP services may include express check-in and dedicated check-in counters, in addition to people, airports move cargo around the clock. Many large airports are located near railway trunk routes, the majority of the worlds airports are non-towered, with no air traffic control presence. Busy airports have air control system. All airports use a pattern to assure smooth traffic flow between departing and arriving aircraft. There are a number of available to pilots, though not all airports are equipped with them. Many airports have lighting that help guide planes using the runways and taxiways at night or in rain, snow, or fog

Public spaces
–
A public space is a social space that is generally open and accessible to people. Roads, public squares, parks and beaches are considered public space. To a limited extent, government buildings which are open to the public, such as libraries are public spaces, although they tend to have restricted areas. Recently, the concept of Shared space has been advanced to enhance the experience of pedestrians in public space used by automobiles. Public space has become something of a touchstone for critical theory in relation to philosophy, geography, visual art, cultural studies, social studies. The term public space is often misconstrued to mean other things such as gathering place. One of the earliest examples of spaces are commons. For example, no fees or paid tickets are required for entry, non-government-owned malls are examples of private space with the appearance of being public space. In Nordic countries like Norway, Sweden and Finland, all areas are considered public space, due to a law. In the United States the right of the people to engage in speech, the government cannot usually limit ones speech beyond what is reasonable in a public space, which is considered to be a public forum. This is not to say that the government can control what one says in their own home or to others, parks, malls, beaches, waiting rooms, etc. may be closed at night. As this does not exclude any specific group, it is not considered a restriction on public use. Entry to public parks cannot be restricted based upon a users residence, in some cultures, there is no expectation of privacy in a public space, however civil inattention is a process whereby individuals are able to maintain their privacy within a crowd. Public space is shared and created for open usage throughout the community. The area is built for a range of types of recreation. The physical setting is socially constructed, which creates a behavior influence, limitations are imposed in the space to prevent certain actions from occurring--public behavior that is considered obnoxious or out of character --and are supported by law or ordinance. Police forces are involved in moving unwanted members of the public from public spaces. In fact, by not being provided suitable access, disabled people are excluded from some spaces

Public square
–
A town square is an open public space commonly found in the heart of a traditional town used for community gatherings. Other names for town square are civic center, city square, urban square, market square, public square, piazza, plaza, most town squares are hardscapes suitable for open markets, music concerts, political rallies, and other events that require firm ground. Being centrally located, town squares are surrounded by small shops such as bakeries, meat markets, cheese stores. At their center is often a fountain, well, monument, many of those with fountains are actually called fountain square. In urban planning, a city square or urban square is an open area in a city. Red Square in Moscow was originally used as a marketplace and later became the stage for Soviet military parades. Similarly, Beijings Tiananmen Square was the scene of both communist parades and anti-government protests, john-F. -Kennedy-Platz was the site of the West Berlin town hall and John F. Kennedys famous Ich bin ein Berliner speech. New York Citys Times Square as well as Bryant Park, Washington, D. C. s National Mall, trafalgar Square in London does the same for the United Kingdom. Saint Peters Square in Vatican City, the enclave within Rome. Yonge-Dundas Square in Toronto is a renowned and famous square in Canada, nathan Phillips Square is a popular square in front of Torontos landmark City Hall. Hviezdoslavovo námestie is one of the squares in Bratislava and a centre of a social life. Dam Square in Amsterdam for the Netherlands, Main Market Square in Kraków, Market Place in Warsaw and Wrocław Main Square for Poland. The City Hall Square, Copenhagen for Denmark, praça do Comércio, in Lisbon, Portugal, was formerly known as the Terreiro do Paço. It was destroyed after the 1755 Lisbon earthquake but was rebuilt, the symmetrical buildings around the square hold government bureaus and ministries. Wenceslas Square is one of the city squares in the New Town of Prague. In Mainland China, Peoples Square is a designation for the central town square of modern Chinese cities. These squares are the site of government buildings, museums and other public buildings, the probably best-known and largest such square in China is Tienanmen Square. The German word for square is Platz, which also means Place and these have been focal points of public life in towns and cities from the Middle Ages to today

Park
–
A park is an area of natural, semi-natural, or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. It may consist of areas, rocks, soil, and trees. In North America, many parks have fields for playing such as soccer, baseball and football. Many parks have trails for walking, biking and other activities, some parks are built adjacent to bodies of water or watercourses and may comprise a beach or boat dock area. Often, the smallest parks are in areas, where a park may take up only a city block or less. Urban parks often have benches for sitting and may contain picnic tables, the largest parks can be vast natural areas of hundreds of thousands of square kilometres, with abundant wildlife and natural features such as mountains and rivers. In many large parks, camping in tents is allowed with a permit, many natural parks are protected by law, and users may have to follow restrictions. Large national and sub-national parks are typically overseen by a ranger or a park warden. Large parks may have areas for canoeing and hiking in the months and, in some northern hemisphere countries. The first parks were English deer parks, land set aside for hunting by royalty and they had walls or thick hedges around them to keep game animals in and people out. It was strictly forbidden for commoners to hunt animals in these deer parks and these game preserves evolved into landscaped parks set around mansions and country houses from the sixteenth century onwards. These may have served as hunting grounds but they also proclaimed the owners wealth, an aesthetic of landscape design began in these stately home parks where the natural landscape was enhanced by landscape architects such as Capability Brown. As cities became crowded, the hunting grounds became places for the public. With the Industrial revolution parks took on a new meaning as areas set aside to preserve a sense of nature in the cities, sporting activity came to be a major use for these urban parks. Areas of outstanding natural beauty were also set aside as national parks to prevent their being spoiled by uncontrolled development, in some parks or time periods with high pollen counts, parks tend to be avoided. Park design is influenced by the purpose and audience, as well as by the available land features. A park intended to provide recreation for children may include a playground, a park primarily intended for adults may feature walking paths and decorative landscaping. Specific features, such as riding trails, may be included to support specific activities, the design of a park may determine who is willing to use it

Beach
–
A beach is a landform along a body of water. It usually consists of particles, which are often composed of rock, such as sand, gravel, shingle, pebbles. The particles comprising a beach are occasionally biological in origin, such as shells or coralline algae. Some beaches have man-made infrastructure, such as posts, changing rooms. They may also have hospitality venues nearby, wild beaches, also known as undeveloped or undiscovered beaches, are not developed in this manner. Wild beaches can be valued for their beauty and preserved nature. Beaches typically occur in areas along the coast where wave or current action deposits, although the seashore is most commonly associated with the word beach, beaches are also found by lakes and alongside large rivers. Beach may refer to, small systems where rock material moves onshore, offshore, or alongshore by the forces of waves and currents, the former are described in detail below, the larger geological units are discussed elsewhere under bars. There are several parts to a beach that relate to the processes that form. The part mostly above water, and more or less influenced by the waves at some point in the tide, is termed the beach berm. The berm is the deposit of material comprising the active shoreline, the berm has a crest and a face — the latter being the slope leading down towards the water from the crest. At the very bottom of the face, there may be a trough, at some point the influence of the waves on the material comprising the beach stops, and if the particles are small enough, winds shape the feature. Where wind is the force distributing the grains inland, the deposit behind the beach becomes a dune and these geomorphic features compose what is called the beach profile. The beach profile changes seasonally due to the change in energy experienced during summer and winter months. In temperate areas where summer is characterised by calmer seas and longer periods between breaking wave crests, the profile is higher in summer. The gentle wave action during this season tends to transport sediment up the beach towards the berm where it is deposited, onshore winds carry it further inland forming and enhancing dunes. Conversely, the profile is lower in the storm season due to the increased wave energy. The removal of sediment from the berm and dune thus decreases the beach profile

Water supply network
–
A water supply system or water supply network is a system of engineered hydrologic and hydraulic components which provide water supply. A water supply system includes, A drainage basin. A raw water collection point where the water accumulates, such as a lake, raw water may be transferred using uncovered ground-level aqueducts, covered tunnels or underground water pipes to water purification facilities. Treated water is transferred using water pipes, Water storage facilities such as reservoirs, water tanks, or water towers. Smaller water systems may store the water in cisterns or pressure vessels, tall buildings may also need to store water locally in pressure vessels in order for the water to reach the upper floors. Additional water pressurizing components such as pumping stations may need to be situated at the outlet of underground or above ground reservoirs or cisterns, a pipe network for distribution of water to the consumers and other usage points. Connections to the sewers are found downstream of the water consumers. Raw water is collected from a water source or from a groundwater source within the watershed that provides the water resource. The raw water is transferred to the water purification facilities using uncovered aqueducts, Water treatment must occur before the product reaches the consumer and afterwards. Water purification usually occurs close to the delivery points to reduce pumping costs. Traditional surface water treatment plants generally consists of three steps, clarification, filtration and disinfection, clarification refers to the separation of particles from the water stream. Chemical addition destabilizes the particle charges and prepares them for either by settling or floating out of the water stream. Sand, anthracite or activated carbon filters refine the water stream, while other methods of disinfection exist, the preferred method is via chlorine addition. Chlorine effectively kills bacteria and most viruses and maintains a residual to protect the supply through the supply network. The product, delivered to the point of consumption, is called potable water if it meets the quality standards required for human consumption. The water is typically pressurised by pumps that pump water into storage tanks constructed at the highest local point in the network, one network may have several such service reservoirs. In small domestic systems, the water may be pressurised by a vessel or even by an underground cistern. This eliminates the need of a water-tower or any other heightened water reserve to supply the water pressure and these systems are usually owned and maintained by local governments, such as cities, or other public entities, but are occasionally operated by a commercial enterprise

Sewage
–
Sewage is a water-carried waste, in solution or suspension, that is intended to be removed from a community. Also known as domestic or municipal wastewater, it is characterized by volume or rate of flow, physical condition, chemical and toxic constituents and it consists mostly of greywater, blackwater, soaps and detergents, and toilet paper. Whether it also contains surface runoff depends on the design of sewer system, all sewage ends up back in the environment, by any of several routes. A basic distinction in its route is whether it undergoes sewage treatment to mitigate its effect on the environment before arriving there, Sewage usually travels from a buildings plumbing either into a sewer, which will carry it elsewhere, or into an onsite sewage facility. Whether it is combined with surface runoff in the sewer depends on the sewer design, before the 20th century, sewers usually discharged into a body of water such as a stream, river, lake, bay, or ocean. There was no treatment, so the breakdown of the waste was left to the ecosystem. Today, the goal is that sewers route their contents to a treatment plant rather than directly to a body of water. In many countries, this is the norm, in developing countries. Thus other goals of modern sewage routing include handling surface runoff separately from sewage, handling greywater separately from toilet waste, proper collection and safe, nuisance-free disposal of the liquid wastes of a community are legally recognized as a necessity in an urbanized, industrialized society. In many developing countries the bulk of domestic and industrial wastewater is discharged without any treatment or after primary treatment only, the term sewage is nowadays regarded as an older term and is being more and more replaced by wastewater. In general American English usage, the sewage and sewerage mean the same thing. Both words are descended from Old French assewer, derived from the Latin exaquare, in American technical and professional English usage, sewerage refers to the infrastructure that conveys sewage. Wastes that result from an industrial processes such as the production or manufacture of goods are classed as industrial wastewater, surface runoff, also known as storm flow or overland flow, is that portion of precipitation that runs rapidly over the ground surface to a defined channel. Sewage is a mixture of chemicals, with many distinctive chemical characteristics. These include high concentrations of ammonium, nitrate, phosphorus, high conductivity, high alkalinity, the organic matter of sewage is measured by determining its biological oxygen demand or the chemical oxygen demand. Sewage also contains the nutrients nitrogen and phosphorus, Sewage can be monitored for both disease-causing and benign organisms with a variety of techniques. Traditional techniques involve filtering, staining, and examining samples under a microscope, sequencing DNA from an environmental sample is known as metagenomics. Sewage has also analyzed to determine relative rates of use of prescription

Electrical grid
–
An electrical grid is an interconnected network for delivering electricity from suppliers to consumers. Power stations may be located near a source, at a dam site, or to take advantage of renewable energy sources. They are usually large to take advantage of the economies of scale. The electric power which is generated is stepped up to a voltage at which it connects to the electric power transmission network. The bulk power transmission network will move the power long distances, sometimes across international boundaries, on arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution level voltage. As it exits the substation, it enters the distribution wiring, finally, upon arrival at the service location, the power is stepped down again from the distribution voltage to the required service voltage. Electrical grids vary in size covering an single building through national grids which cover whole countries. Early electric energy was produced near the device or service requiring that energy, in the 1880s, electricity competed with steam, hydraulics, and especially coal gas. Coal gas was first produced on premises but later evolved into gasification plants that enjoyed economies of scale. In the industrialized world, cities had networks of piped gas, but gas lamps produced poor light, wasted heat, made rooms hot and smoky, and gave off hydrogen and carbon monoxide. In the 1880s electric lighting soon became advantageous compared to gas lighting, Electric utility companies took advantage of economies of scale and moved to centralized power generation, distribution, and system management. With long distance power transmission it became possible to interconnect stations to balance load, merz was appointed head of a Parliamentary Committee and his findings led to the Williamson Report of 1918, which in turn created the Electricity Supply Bill of 1919. The bill was the first step towards an integrated electricity system, the Electricity Act of 1926 led to the setting up of the National Grid. The Central Electricity Board standardized the nations electricity supply and established the first synchronized AC grid and this started operating as a national system, the National Grid, in 1938. In the United States in the 1920s, utilities formed joint-operations to share peak load coverage, no longer were electric utilities built as vertical monopolies, where generation, transmission and distribution were handled by a single company. Now, the three stages could be split among various companies, in an effort to provide accessibility to high voltage transmission. The Energy Policy Act of 2005 allowed incentives and loan guarantees for energy production. In France, electrification began in the 1900s, with 700 communes in 1919, and 36,528 in 1938

Dam
–
A dam is a barrier that impounds water or underground streams. Reservoirs created by not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture. Hydropower is often used in conjunction with dams to generate electricity, a dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. The word dam can be traced back to Middle English, and before that, from Middle Dutch, the first known appearance of dam occurs in 1165. However, there is one village, Obdam, that is mentioned in 1120. The word seems to be related to the Greek word taphos, so the word should be understood as dike from dug out earth. The names of more than 40 places from the Middle Dutch era such as Amsterdam and Rotterdam, early dam building took place in Mesopotamia and the Middle East. Dams were used to control the level, for Mesopotamias weather affected the Tigris. The earliest known dam is the Jawa Dam in Jordan,100 kilometres northeast of the capital Amman and this gravity dam featured an originally 9-metre-high and 1 m-wide stone wall, supported by a 50 m-wide earth rampart. The structure is dated to 3000 BC, the Ancient Egyptian Sadd-el-Kafara Dam at Wadi Al-Garawi, located about 25 km south of Cairo, was 102 m long at its base and 87 m wide. The structure was built around 2800 or 2600 BC as a dam for flood control. During the Twelfth Dynasty in the 19th century BC, the Pharaohs Senosert III, Amenemhat III, two dams called Ha-Uar running east-west were built to retain water during the annual flood and then release it to surrounding lands. The lake called Mer-wer or Lake Moeris covered 1,700 km2 and is today as Berkat Qaroun. One of the wonders of the ancient world was the Great Dam of Marib in Yemen. Repairs were carried out during various periods, most important around 750 BC and these extensive works were not actually finalized until 325 AD and allowed the irrigation of 25,000 acres. By the mid-late 3rd century BC, an intricate water-management system within Dholavira in modern-day India was built, the system included 16 reservoirs, dams and various channels for collecting water and storing it. Eflatun Pınar is a Hittite dam and spring temple near Konya and it is thought to be from the time of the Hittite empire between the 15th and 13th century BC

Asset
–
In financial accounting, an asset is an economic resource. Anything tangible or intangible that can be owned or controlled to produce value, simply stated, assets represent value of ownership that can be converted into cash. The balance sheet of a firm records the value of the assets owned by that firm. It covers money and other valuables belonging to an individual or to a business, one can classify assets into two major asset classes, tangible assets and intangible assets. Tangible assets contain various subclasses, including current assets and fixed assets, current assets include inventory, while fixed assets include such items as buildings and equipment. Intangible assets are resources and rights that have a value to the firm because they give the firm some kind of advantage in the marketplace. Examples of intangible assets include goodwill, copyrights, trademarks, patents and computer programs, an asset is a resource controlled by the entity as a result of past events and from which future economic benefits are expected to flow to the entity. One of the most widely accepted accounting definitions of asset is the one used by the International Accounting Standards Board, employees are not considered assets like machinery is, even though they can generate future economic benefits. This is because an entity does not have sufficient control over its employees to satisfy the Frameworks definition of an asset, similarly, in economics an asset is any form in which wealth can be held. The accounting equation is the structure of the balance sheet. It relates assets, liabilities, and owners equity, Assets = Liabilities + Capital Liabilities = Assets − Capital Equity = Assets − Liabilities Assets are listed on the balance sheet. On a companys balance sheet certain divisions are required by generally accepted accounting principles, Assets can be divided into e. g. current assets and fixed assets, often with further subdivisions such as cash, receivables and inventory. Assets are formally controlled and managed within larger organizations via the use of asset tracking tools and these monitor the purchasing, upgrading, servicing, licensing, disposal etc. of both physical and non-physical assets. Current assets are cash and other assets expected to be converted to cash or consumed either in a year or in the operating cycle and these assets are continually turned over in the course of a business during normal business activity. There are 5 major items included into current assets, Cash and cash equivalents – it is the most liquid asset, which includes currency, deposit accounts, short-term investments – include securities bought and held for sale in the near future to generate income on short-term price differences. Receivables – usually reported as net of allowance for non-collectable accounts, inventory – trading these assets is a normal business of a company. The inventory value reported on the sheet is usually the historical cost or fair market value. This is known as the lower of cost or market rule, prepaid expenses – these are expenses paid in cash and recorded as assets before they are used or consumed

Building
–
A building or edifice is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. To better understand the term building compare the list of nonbuilding structures, Buildings serve several needs of society – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a division of the human habitat. Ever since the first cave paintings, buildings have become objects or canvasses of much artistic expression. In recent years, interest in planning and building practices has also become an intentional part of the design process of many new buildings. The word building is both a noun and a verb also an adverb, the structure itself and the act of making it. As a noun, a building is a structure that has a roof and walls and stands more or less permanently in one place, there was a building on the corner. In the broadest interpretation a fence or wall is a building, however, the word structure is used more broadly than building including natural and man-made formations and does not necessarily have walls. Structure is more likely to be used for a fence, as a verb, building is the act of construction. Structural height in technical usage is the height to the highest architectural detail on building from street-level, depending on how they are classified, spires and masts may or may not be included in this height. Spires and masts used as antennas are not generally included, the definition of a low-rise vs. a high-rise building is a matter of debate, but generally three storeys or less is considered low-rise. A report by Shinichi Fujimura of a shelter built 500000 years ago is doubtful since Fujimura was later found to have faked many of his findings. Supposed remains of huts found at the Terra Amata site in Nice purportedly dating from 200000 to 400000 years ago have also called into question. There is clear evidence of homebuilding from around 18000 BC, Buildings became common during the Neolithic. Single-family residential buildings are most often called houses or homes, residential buildings containing more than one dwelling unit are called a duplex, apartment building to differentiate them from individual houses. A condominium is an apartment that the occupant owns rather than rents, houses which were built as a single dwelling may later be divided into apartments or bedsitters, they may also be converted to another use e. g. an office or a shop. Building types may range from huts to multimillion-dollar high-rise apartment blocks able to house thousands of people, increasing settlement density in buildings is usually a response to high ground prices resulting from many people wanting to live close to work or similar attractors. Other common building materials are brick, concrete or combinations of either of these with stone, also if the residents are in need of special care such as a nursing home, orphanage or prison, or in group housing like barracks or dormitories

Public capital

Public capital is the aggregate body of government-owned assets that are used as a means for private productivity. Often, public capital is defined as government outlay, in terms of money, in 1988, the U. S. infrastructure system including all public and private non-residential capital stock was valued at $7 trillion, an immense portfolio to operate and manage. And according to the Congressional Budget Office, in 2004 the U. S, while public spending on infrastructure grew by 1. 7% annually between 1956 and 2004, it has remained constant as a share of GDP since early 1980s. The American Society of Civil Engineers have continued to give low marks, averaging a D grade, in 2009, each category of infrastructure varied from C+ to D- grades with an estimated $2.2 trillion of needed public capital investment. The aviation sector remains mired in continued delays in the reauthorization of federal programs, one in four rural bridges and one in three urban bridges are structurally deficient. States are understaffed and underfunded to conduct safety inspections of dams, texas alone has only seven engineers and an annual budget of $435,000 to oversee more than 7,400 dams. Electricity demand outpaces energy supply transmission and generation, almost half of the water locks maintained by the U. S. Army Corps of Engineers are functionally obsolete. Drinking water faces an annual shortfall of $11 billion to manage their aging facilities, leaking pipes lose an estimated 7 billion US gallons of clean drinking water a day. Under tight budgets, national, state, and local parks suffer neglect, without adequate funding, rail cannot meet future freight tonnage load. Schools require a staggering $127 billion to bring facilities to decent operating condition, billions of gallons of untreated sewage continue to be discharged into U. S. ’s surface waters each year. One of the most classic macroeconomic inquiries is the effect of capital investment on economic growth. While many analysts debate the magnitude, evidence has shown a significant positive relationship between infrastructure investment and economic performance. U. S. Federal Reserve economist David Alan Aschauer asserted an increase of the capital stock by 1% would result in an increase of the total factor productivity by 0. 4%. Aschauer argues that the age of the 1950s and 1960s were partly due to the post-World War II substantial investment in core infrastructure. Conversely, the drop of U. S. productivity growth in the 1970s and 1980s was in response to the decrease of continual public capital investment, likewise, the European Union nations have declined public capital investment through the same years, also witnessing declining productivity growth rates. A similar situation emerges in developing nations, however, this relationship depends on initial levels of public capital and income levels for the country. Thus, OECD countries witness a stronger positive link in the term while non-OECD countries experience a stronger positive link in the long term. Hence, developing countries can benefit from non-concessional foreign borrowing to finance high-prospect public capital investments, additionally, public capital has an indirect influence on multifactor productivity as it affects the other two inputs of labor and private capital

Economics

Economics is a social science concerned chiefly with description and analysis of the production, distribution, and consumption of goods and services according to the Merriam-Webster Dictionary. Economics focuses on the behaviour and interactions of economic agents and how economies work, consistent with this focus, textbooks often distinguish between microeconomics and macroeconomics. Microeconomics examines the behaviour of elements in the economy, including individual agents and markets, their interactions. Individual agents may include, for example, households, firms, buyers, macroeconomics analyzes the entire economy and issues affecting it, including unemployment of resources, inflation, economic growth, and the public policies that address these issues. Economic analysis can be applied throughout society, as in business, finance, health care, Economic analyses may also be applied to such diverse subjects as crime, education, the family, law, politics, religion, social institutions, war, science, and the environment. At the turn of the 21st century, the domain of economics in the social sciences has been described as economic imperialism. The ultimate goal of economics is to improve the conditions of people in their everyday life. There are a variety of definitions of economics. Some of the differences may reflect evolving views of the subject or different views among economists, to supply the state or commonwealth with a revenue for the publick services. Say, distinguishing the subject from its uses, defines it as the science of production, distribution. On the satirical side, Thomas Carlyle coined the dismal science as an epithet for classical economics, in this context and it enquires how he gets his income and how he uses it. Thus, it is on the one side, the study of wealth and on the other and more important side, a part of the study of man. He affirmed that previous economists have usually centred their studies on the analysis of wealth, how wealth is created, distributed, and consumed, but he said that economics can be used to study other things, such as war, that are outside its usual focus. This is because war has as the goal winning it, generates both cost and benefits, and, resources are used to attain the goal. If the war is not winnable or if the costs outweigh the benefits. Some subsequent comments criticized the definition as overly broad in failing to limit its subject matter to analysis of markets, there are other criticisms as well, such as in scarcity not accounting for the macroeconomics of high unemployment. The same source reviews a range of included in principles of economics textbooks. Among economists more generally, it argues that a particular definition presented may reflect the direction toward which the author believes economics is evolving, microeconomics examines how entities, forming a market structure, interact within a market to create a market system

Politics

Politics is the process of making decisions applying to all members of each group. More narrowly, it refers to achieving and exercising positions of governance — organized control over a human community, furthermore, politics is the study or practice of the distribution of power and resources within a given community as well as the interrelationship between communities. It is very often said that politics is about power, a political system is a framework which defines acceptable political methods within a given society. History of political thought can be traced back to antiquity, with seminal works such as Platos Republic, Aristotles Politics. Formal Politics refers to the operation of a system of government and publicly defined institutions. Political parties, public policy or discussions about war and foreign affairs would fall under the category of Formal Politics, many people view formal politics as something outside of themselves, but that can still affect their daily lives. Semi-formal Politics is Politics in government associations such as neighborhood associations, informal Politics is understood as forming alliances, exercising power and protecting and advancing particular ideas or goals. Generally, this includes anything affecting ones daily life, such as the way an office or household is managed, informal Politics is typically understood as everyday politics, hence the idea that politics is everywhere. The word comes from the same Greek word from which the title of Aristotles book Politics also derives, the book title was rendered in Early Modern English in the mid-15th century as Polettiques, it became politics in Modern English. The history of politics is reflected in the origin, development, the origin of the state is to be found in the development of the art of warfare. Historically speaking, all communities of the modern type owe their existence to successful warfare. Kings, emperors and other types of monarchs in many countries including China, of the institutions that ruled states, that of kingship stood at the forefront until the French Revolution put an end to the divine right of kings. Nevertheless, the monarchy is among the political institutions, dating as early as 2100 BC in Sumeria to the 21st century AD British Monarchy. Kingship becomes an institution through the institution of Hereditary monarchy, the king often, even in absolute monarchies, ruled his kingdom with the aid of an elite group of advisors, a council without which he could not maintain power. As these advisors and others outside the monarchy negotiated for power, constitutional monarchies emerged, long before the council became a bulwark of democracy, it rendered invaluable aid to the institution of kingship by, Preserving the institution of kingship through heredity. Preserving the traditions of the social order, being able to withstand criticism as an impersonal authority. Being able to manage a greater deal of knowledge and action than an individual such as the king. The greatest of the subordinates, the earls and dukes in England and Scotland

Construction
–
Construction is the process of constructing a building or infrastructure. Construction as an industry comprises six to nine percent of the domestic product of developed countries. Construction starts with planning, design, and financing, and continues until the project is built, large-scale construction requires collaboration across multiple disciplines. An architect normally manages the job, and a manager, design engineer. For the successful execution of a project, effective planning is essential, the largest construction projects are referred to as megaprojects. Construction is a term meaning the art and science to form objects, systems, or organizations. Construction is used as a verb, the act of building, and a noun, how a building was built, in general, there are three sectors of construction, buildings, infrastructure and industrial. Building construction is further divided into residential and non-residential. Infrastructure is often called heavy/highway, heavy civil or heavy engineering and it includes large public works, dams, bridges, highways, water/wastewater and utility distribution. Industrial includes refineries, process chemical, power generation, mills, there are other ways to break the industry into sectors or markets. Engineering News-Record is a magazine for the construction industry. Each year, ENR compiles and reports on data about the size of design and they publish a list of the largest companies in the United States and also a list the largest global firms. In 2014, ENR compiled the data in nine market segments and it was divided as transportation, petroleum, buildings, power, industrial, water, manufacturing, sewer/waste, telecom, hazardous waste plus a tenth category for other projects. In their reporting on the Top 400, they used data on transportation, sewer, hazardous waste, the Standard Industrial Classification and the newer North American Industry Classification System have a classification system for companies that perform or otherwise engage in construction. To recognize the differences of companies in this sector, it is divided into three subsectors, building construction, heavy and civil engineering construction, and specialty trade contractors, there are also categories for construction service firms and construction managers. Building construction is the process of adding structure to real property or construction of buildings, the majority of building construction jobs are small renovations, such as addition of a room, or renovation of a bathroom. Often, the owner of the property acts as laborer, paymaster, for this reason, those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a positive outcome. Residential construction practices, technologies, and resources must conform to local building authority regulations, materials readily available in the area generally dictate the construction materials used
