Query: How many people are employed by the company G4S?
It is the world's largest security company measured by revenues and has operations in more than 90 countries. With over 570,000 employees, it is the world's third-largest private employer, the largest European and African private employer, and among the largest on the London Stock Exchange. G4S was founded in 2004 by the merger of the UK-based Securicor plc with the Denmark-based Group 4 Falck.

G4S has its origins in a guarding business founded in Copenhagen in 1901 by Marius Hogrefe, originally known as "København Frederiksberg Nattevagt" ("Copenhagen and Frederiksberg Night Watch") and subsequently renamed "Falck" ("Falcon").
In 2000, Group 4, a security firm formed in the 1960s, merged with "Falck" to form "Group 4 Falck" and by 2000 the company was described as "the world's largest private security systems company". In 2002 "Group 4 Falck" went on to buy The Wackenhut Corporation in the United States.
He formed GSM with a colleague from his days at ICI in 1974. The company specialises in labels and barcoding equipment, sheet metal assemblies and automotive components. Through many acquisitions, the company employed over 400 people at nine sites across the United Kingdom by the time of Dodd's death.

The British intelligence agency Government Communications Headquarters (GCHQ)'s secret mass surveillance program Optic Nerve and National Security Agency (NSA) were reported to be indiscriminately collecting still images from Yahoo webcam streams from millions of mostly innocent Yahoo webcam users, among other things creating a database for facial recognition for future use. Optic Nerve took a still image from the webcam stream every 5 minutes.
The complex is operated by the GEO Group. With a combined capacity of 3,763 prisoners in its three sub-complexes, it has been called the largest private prison in the world. The GEO Group houses prisoners at this facility under contract with the U.S. Federal Bureau of Prisons and the Arizona Department of Corrections. Most prisoners at the complex are low-security criminal aliens, serving sentences of one to five years for drug offenses or immigration violations. They face deportation when released.
Quantum computing in Canada is also gaining a foothold as evidenced by D-Wave Systems, a Burnaby-based quantum computing company founded in 1999 where in May 2013 it was announced that a collaboration between NASA, Google and the Universities Space Research Association (USRA) launched a Quantum Artificial Intelligence Lab using a 512 qubit D-Wave Two that would be used for research into machine learning, among other fields of study. Though the field is still in its infancy, experiments have been carried out in which quantum computational operations were executed on a very small number of qubits. Both practical and theoretical research continues, and many national governments and military funding agencies support quantum computing research to develop quantum computers for both civilian and national security purposes, such as cryptanalysis.
A SIGINT Activity Designator (or SIGAD) identifies a signals intelligence (SIGINT) line of collection activity associated with a signals collection station, such as a base or a ship. For example, the SIGAD for Menwith Hill in the UK is USD1000. SIGADs are used by the signals intelligence agencies of the United States, the United Kingdom, Canada, Australia and New Zealand.
In 1930, J. Clarence Karcher and Eugene McDermott founded Geophysical Service, an early provider of seismic exploration services to the petroleum industry. In 1939, the company reorganized as Coronado Corp., an oil company with Geophysical Service Inc (GSI), now as a subsidiary. On December 6, 1941, McDermott along with three other GSI employees, J. Erik Jonsson, Cecil H. Green, and H.B. Peacock purchased GSI. During World War II, GSI expanded their services to include electronics for the U.S. Army, Signal Corps, and the U.S. Navy. In 1951, the company changed its name to Texas Instruments, with GSI becoming a wholly owned subsidiary of the new company.
Headquartered in Melbourne, Florida, the company has approximately $7 billion of annual revenue. It is the largest private-sector employer in Brevard County, Florida (approximately 6,000). The company was the parent of Intersil (Harris Semiconductor). Most of the wireless start-ups in South Brevard County were founded and are staffed by former Harris Corporation engineers and technicians. The company's Digital Telephone Systems (DTS) division was sold to Teltronics.
CNS Y-12 currently employs approximately 4,700 people. About 1,500 additional personnel work onsite as employees of organizations that include UT-Battelle, Science Applications International Corporation, Bechtel Jacobs, UCOR, and WSI Oak Ridge (an American-controlled unit of G4S Secure Solutions), which holds the security contract for the site.
In January 2011, Harris re-opened its Calgary, Alberta avionics operation, Harris Canada Inc.. The expanded facility's operations include among others the support of the work to be completed under the company's six-year, $273 million (CAD) services contract with the Government of Canada for the CF-18 Avionics Optimized Weapon System Support (OWSS) program.
"The Doughnut" is the nickname given to the headquarters of the Government Communications Headquarters (GCHQ), a British cryptography and intelligence agency. It is located on a site in Benhall, in the suburbs of Cheltenham, Gloucestershire, in South West England. The Doughnut houses 5,500 employees; GCHQ is the largest single employer in Gloucestershire. Built to modernise and consolidate GCHQ's multiple buildings in Cheltenham, The Doughnut was completed in 2003, and GCHQ moved into the building in 2004. It is the largest building constructed for secret intelligence operations outside the United States. The Doughnut was too small for the number of staff at its completion, and a second building in a secret and undisclosed location in the 'Gloucestershire area' now also accommodates staff from GCHQ. The Doughnut is surrounded by car and bicycle parking in concentric rings, and well protected by security.
International Ecological Society: Distinguished Statistical Ecologist (1998)
The National Geospatial-Intelligence Agency (NGA) oversees the charting of international waters for United States Department of Defense purposes. The United States Navys Naval Oceanographic Office conducts many of these oceanic surveys. The United States Army Corps of Engineers conducts hydrographic surveys supporting its responsibility for the major waterway projects that include navigation and flood control. Hydrographic data from those surveys is published by districts. Such data is incorporated into both NOAA and NGA products and the Corps engages in efforts to improve hydrographic collection methods. Military combat organizations such as the U.S. Navys SEALs and military engineering units have specialized hydrographic reconnaissance survey capabilities.
Global Ecosystem Dynamics Investigation lidar (GEDI, pronounced ) is a NASA mission to measure how deforestation has contributed to atmospheric CO concentrations. A full-waveform Lidar will be attached to the International Space Station to provide the first global, high-resolution observations of forest vertical structure. This will allow scientists to map habitats and biomass, particularly in the tropics, providing detail on the Earth's carbon cycle.
Located in the middle of a still-growing international city, CGE reflects the ethnic and international flavor of the city of Coral Gables near the offices of more than 100 multinational corporations. CGE serves families from all socioeconomic backgrounds, including the affluent middle class and many recent immigrants from developing nations in Latin America. 26% of its students qualified for free and reduced lunch. CGE's population is 33% White non-Hispanic, 61% Hispanic, 2% Black non-Hispanic and 4% other non-Hispanic. 12% are limited English proficient and 33% qualify for the Exceptional Student Education Program.
It is the only tunnel that runs from east to the west of the Rock of Gibraltar, and during World War Two the tunnel was reworked and a 3,000-square-metre area roughly halfway down it became a state-of-the-art communications centre. This Allied Command Headquarters centre was protected from enemy bombs by metres of rock in every direction and contained the board room where the invasion of North Africa (Operation Torch) was planned by Dwight Eisenhower. As a result, Eisenhower not only commanded the operation, but he was the first non-British person to command Gibraltar in 200 years. It had its own systems for fresh air, electricity, lighting and communication links to the outside world.
The Geological Engineering Company folded due to a drop in the price of oil. In 1925, oil prices had rebounded, and Karcher helped to form Geophysical Research Corporation (GRC) as part of the oil company Amerada. In 1930, Karcher left GRC and helped to found Geophysical Service Incorporated (GSI). GSI was one of the most successful seismic contracting companies for over 50 years and was the parent of an even more successful company, Texas Instruments. Early GSI employee Henry Salvatori left that company in 1933 to found another major seismic contractor, Western Geophysical. 
Many other companies using reflection seismology in hydrocarbon exploration, hydrology, engineering studies, and other applications have been formed since the method was first invented. Major service companies today include CGG, ION Geophysical, Petroleum Geo-Services, Polarcus, TGS and WesternGeco. Most major oil companies also have actively conducted research into seismic methods as well as collected and processed seismic data using their own personnel and technology. Reflection seismology has also found applications in non-commercial research by academic and government scientists around the world.

The proliferation of technology companies has led to the region's nickname, "Silicon Hills", and spurred development that greatly expanded the city.
Justice secretary Liz Truss informed Members of Parliament that insufficient staffing lay at the root of the Birmingham riot. She said G4S would have to pay the costs of ten highly trained public sector Tornado elite teams dispatched to end the 12-hour riot at its Birmingham prison. Three hundred and eighty prisoners were transferred from wrecked wings of the prison to other jails across England, but their dispersal led to two incidents at HM Prison Hull on Sunday and another at HM Prison Cardiff and yet another at HM Prison Swaleside. At the riot's start, prisoners took keys from a G4S guard. At 10:00 a.m. G4S deployed two Tornado teams but that response was insufficient. Seven public sector Tornado teams were therefore necessarily dispatched to Birmingham at 11:29 a.m. “Shortly after 10 p.m., the teams had secured all four wings," she said. Labour MPs pressed Truss over whether prior warnings from the Birmingham independent monitoring board had been acted upon, and about the consequences of a 700 million pound budget cut and the reduction of 7,000 prison officers on the overall stability of the Prison Service. Labour said the riot should prompt the government to review the operation of prisons by private companies such as G4S and Serco. Although Truss repeatedly refused to acknowledge if she had read the Birmingham prison watchdog’s October report that warned of the need for urgent action to tackle understaffing and the spread of psychoactive drugs, she said they had been discussed with the prison's governor. The Truss statement followed still another warning from John Thornhill, the president of the independent monitoring board. He said insufficient staff had caused rising levels of violence in prisons in England and Wales: “It is the board’s view, echoed by prison staff, that there are insufficient staff numbers to deal with many of the day-to-day situations that occur in a local prison… The result, as we have seen in recent weeks, is an increase in riots that damage the system.” “The impact of this unrestrained violence is that a large number of prisoners have to be transferred to other prisons that are already stretched with their own problems and staffing issues.”
On March 25, 2004, Comcast's G4 gaming channel announced a merger with TechTV. This move became hugely controversial among loyal fans of TechTV. Around May 6, G4 announced the termination of 250 employees from the San Francisco office by July 10, 2004, allowing approximately 80 to 100 employees to transition to G4's main office in Los Angeles, California if they agreed to relocate there. Norton chose to stay in San Francisco instead of moving to Los Angeles, and left the company.
Gurkha Services was formed in 2007 and employed 600 people as of November 2011. In the north east of England they were hired in an attempt to reduce metal theft from railways.
In late 2012, G4's studio programming ceased in preparation for its relaunch as Esquire Network on September 23, 2013, as part of a licensing deal with Hearst Corporation, owner of "Esquire" magazine. However, on September 9, 2013, NBCUniversal announced that Esquire Network would instead replace sister channel, Style, leaving G4 "as is for the foreseeable future, though it's highly unlikely the company will invest in more original programming". In August 2013, it was reported that approximately 61,217,000 American households (53.61% of households with television) were receiving G4, though this declined with later removals by several cable services as carriage agreements expired.
