West’s mother, Anita Mason, remembered her 19-year-old daughter as full of promise. Investigators credited friends of Butler, a college student, for using social media to set up a fake account to bait Wheeler-Weaver and lure him to Montclair. “But each of these women’s lives mattered.” They were killed and then he went on about his day as if nothing had happened,” Assistant Essex County Prosecutor Adam Wells said. “The defendant believed these victims were disposable.

On the surface of Earth, at far lower temperatures than the surface of the Sun, some thermal radiation consists of infrared in the mid-infrared region, much longer than in sunlight. Nearly all the infrared radiation in sunlight is near infrared, shorter than 4 micrometers. Of this energy, 527 watts is infrared radiation, 445 watts is visible light, and 32 watts is ultraviolet radiation. At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Sunlight, at an effective temperature of 5,780 kelvins (5,510 ☌, 9,940 ☏), is composed of near-thermal-spectrum radiation that is slightly more than half infrared. Increasingly, terahertz radiation is counted as part of the microwave band, not infrared, moving the band edge of infrared to 0.1 mm (3 THz). Beyond infrared is the microwave portion of the electromagnetic spectrum. This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Typically, it is taken to extend from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). ![]() There is no universally accepted definition of the range of infrared radiation. Non-military uses include thermal efficiency analysis, environmental monitoring, industrial facility inspections, detection of grow-ops, remote temperature sensing, short-range wireless communication, spectroscopy, and weather forecasting.ĭefinition and relationship to the electromagnetic spectrum Humans at normal body temperature radiate chiefly at wavelengths around 10 μm (micrometers). Military and civilian applications include target acquisition, surveillance, night vision, homing, and tracking. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect the overheating of electrical components. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space such as molecular clouds, to detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared radiation is used in industrial, scientific, military, commercial, and medical applications. Infrared spectroscopy examines absorption and transmission of photons in the infrared range. It excites vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry. Infrared radiation is emitted or absorbed by molecules when changing rotational-vibrational movements. The balance between absorbed and emitted infrared radiation has an important effect on Earth's climate. Slightly more than half of the energy from the Sun was eventually found, through Herschel's studies, to arrive on Earth in the form of infrared. In 1800 the astronomer Sir William Herschel discovered that infrared radiation is a type of invisible radiation in the spectrum lower in energy than red light, by means of its effect on a thermometer. It was long known that fires emit invisible heat in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). It is therefore invisible to the human eye. Infrared (sometimes called infrared light and IR) is electromagnetic radiation (EMR) with wavelengths longer than those of visible light and shorter than radio waves. ![]() This false-color infrared space telescope image has blue, green and red corresponding to 3.4, 4.6, and 12 μm wavelengths, respectively. ![]() ![]() ![]() The Bureau had been put in charge of domestic intelligence and had already built an extensive network of sources, with law enforcement around the country serving as an important set of eyes and ears. ![]() It clearly needed more and better intelligence to understand the threats posed by the Axis powers. Learning the counterintelligence ropes as it went along, the FBI was ultimately given the lead in these cases and uncovered some 50 spies operating in America before the nation entered the war, including a massive ring led by long-time German agent Fritz Duquesne.Īs the new decade opened, the nation was drifting towards war and increasingly supporting the Allied cause. The intelligence arms of the Army and Navy had noticed increased activity by German and Japanese spies in the late 1930s and began working with the Bureau to disrupt it. In 1936, the President and Secretary of State tasked the Bureau with gathering intelligence on the potential threats to national security posed by fascist and communist groups. In 1934, he had first asked the FBI to determine if American Nazi groups were working with foreign agents. President Roosevelt was concerned-he suspected these groups were allying themselves to foreign political movements seeking to overturn democracy and were crossing the line into criminal activity. And Americans were increasingly becoming enamored of communism and its seductive promise of a classless state the Communist Party of the United States and other like-minded organizations soon boasted more than a million members. Groups like the German American Bund and the Silver Shirts that embraced the Nazi vision were becoming more and more vocal. The lingering Great Depression provided fertile ground for fascism. But, remembering how helpless it was against German sabotage in the years leading up to World War I, the nation wasn’t taking any chances at home. It formally joined with Germany and Mussolini’s Italy to form the Axis powers in September 1940.Ĭushioned by twin oceans, an isolationist America was staying out of the fray-for the time being. It invaded China in 1937, seized its northern capital, began taking control of coastal areas and nearby islands dotting the Pacific, and even deliberately sank an American gunboat. In the Far East, Japan was making military waves as well. England and France had seen enough and declared war. ![]() But in 1939, Hitler seized the rest of the Czechoslovakia and invaded Poland. England and France, hoping to cut their losses through appeasement, acceded to the takeovers. He meant to build an empire-the Third Reich-and within a few years he’d annexed Austria and the Sudetenland, a German-speaking region in Czechoslovakia. Hitler wasted little time rearming the country. Five years earlier, less than a month after a cornered Dillinger had reached for his gun the last time, a power-hungry Adolph Hitler had declared himself “Führer” and taken total control of Germany. They threatened not only the fate of peoples and nations, but the survival of democracy itself.Īcross the Atlantic in Europe, 1939 was a dark turning point. They were hyper-aggressive fascist dictators, fanatical militarists, and revolution-exporting communists-along with their legions of spies, saboteurs, and subversive agents-who sought to invade, infiltrate, or even conquer entire swaths of territory, if not the world. But now, with the world rushing headlong into war and the pendulum swinging back towards national security concerns, the FBI would need to refocus and retool its operations once again.Īt the start of the decade, the public enemies were almost entirely homegrown-from “Scarface” to “Baby Face.” The next wave of villains would come primarily from afar, and they were in many respects bigger and badder still. The Bureau had reformed itself on the fly it was stronger and more capable than ever. Heading into the late 1930s, fresh off a victory over the gun-slinging gangsters, the FBI hardly had time to catch its collective breath. ![]() ![]() ![]() This method is inappropriate for the vast majority of users – advanced or otherwise – and thus will not be covered. That’s a much more time consuming process, and you’ll be digging around in a variety of system level directories. The last option, which we’re not going to cover here due to complexity and variability of each users configuration and what packages they have installed, is to manually delete all Homebrew directories, dependencies, formula, and all related files from the wide-ranging Homebrew directory locations, including removing every individual item in the Homebrew installed package location of the Mac. This will also remove any packages with it, but if you only want to uninstall certain formula and packages rather than Homebrew entirely you should instead focus on these instructions. Whether you use either method outlined above, Homebrew will be uninstalled.

The NOTECHS system is used to evaluate non-technical skills. CRM training is now a mandated requirement for commercial pilots working under most regulatory bodies, including the FAA (US) and EASA (Europe). In many operational systems, skill areas often overlap, and are not confined to multi-crew craft or equipment, and relate to single operator equipment or craft.Īviation organizations including major airlines and military aviation have introduced CRM training for crews. Interpersonal skills are regarded as communications and a range of behavioral activities associated with teamwork. In this context, cognitive skills are defined as the mental processes used for gaining and maintaining situational awareness, for solving problems and for making decisions. CRM can be defined as a system that uses resources to promote safety within the workplace.ĬRM is concerned with the cognitive and interpersonal skills needed to manage resources within an organized system rather than with the technical knowledge and skills required to operate equipment. When CRM techniques are applied to other arenas, they are sometimes given unique labels, such as maintenance resource management, bridge resource management, or maritime resource management.ĬRM training encompasses a wide range of knowledge, skills, and attitudes including communications, situational awareness, problem solving, decision making, and teamwork together with all the attendant sub-disciplines which each of these areas entails. The current generic term "crew resource management" (CRM) has been widely adopted but is also known as cockpit resource management flightdeck resource management and command, leadership and resource management.

CRM training concepts have been modified for use in a wide range of activities including air traffic control, ship handling, firefighting, and surgery, in which people must make dangerous, time-critical decisions. Studies have shown the use of CRM by both work groups reduces communication barriers and problems can be solved more efficiently, leading to increased safety. United Airlines trained their flight attendants to use CRM in conjunction with the pilots to provide another layer of enhanced communication and teamwork. By the 1990s, CRM had become a global standard. In the US, United Airlines was the first airline to launch a comprehensive CRM program, starting in 1981. A few weeks later, NASA held a workshop on the topic, endorsing this training. ĬRM grew out of the 1977 Tenerife airport disaster, in which two Boeing 747 aircraft collided on the runway, killing 583 people. While retaining a command hierarchy, the concept was intended to foster a less-authoritarian cockpit culture in which co-pilots are encouraged to question captains if they observed them making mistakes. The term "cockpit resource management"-which was later generalized to "crew resource management"-was coined in 1979 by NASA psychologist John Lauber, who for several years had studied communication processes in cockpits. The issues surrounding that crash included a DC-8 crew running out of fuel over Portland, Oregon, while troubleshooting a landing gear problem. Despite the considerable development of electronic aids since then, many principles he developed continue to prove effective.ĬRM in the US formally began with a National Transportation Safety Board (NTSB) recommendation written by NTSB Air Safety Investigator and aviation psychologist Alan Diehl during his investigation of the 1978 United Airlines Flight 173 crash. Its founder is David Beaty, a former Royal Air Force and a BOAC pilot who wrote " The Human Factor in Aircraft Accidents" (1969). ![]() CRM is primarily used for improving aviation safety and focuses on interpersonal communication, leadership, and decision making in aircraft cockpits.

That said, the relatively recent reunification of West and East Germany in 1991 meant that post-WWII growth was mostly concentrated in West Germany (and West Berlin). Berlin is the most populated at 3.5 million residents in the city proper, and 6 million in the wider urban area. Unlike France, Germany has many dense cities and regions, with Berlin, Munich, Stuttgart, and Cologne all having over a million residents. Many residents in the Paris metropolitan area are employed in the service sector, which makes up one-third of France’s $2.78 trillion gross domestic product. But a staggering one-fifth of the French population lives in Paris and its surrounding metro-the most populous urban area in Europe.

Let’s take a look at how the population spreads out in different countries around the world. France and Germany: Population Density Spikes and Troughs He used popular programming language R and a path-tracing package, Rayshader, to create the maps. This series of 3D maps from Terence Teo, an associate professor at Seton Hall University, renders the population density of six countries using open-source data from Kontur Population. But none of this growth has been evenly spread out, including within countries. In the last 100 years, the global population more than quadrupled. By 2050, the population is projected to grow to 10 billion. With the emergence of smart and green cities, the quality of life for many urban dwellers will likely continue to improve, and more large urban areas will morph into megacities.Īs of 2022, Earth has 8 billion humans. Convenience, better jobs, easier access to social services, and higher wages are among the many reasons people are likely to continue to move to cities, even in the post-COVID era. While there are certainly downsides to mass urbanization, like pollution and overcrowding, the upsides clearly outweigh the negatives for most people. Since 2012, deaths in the EU have actually been outpacing births-and in 2019, there were 4.7 million deaths compared to 4.2 million births, though net migration kept population numbers from falling. Urban growth will continue mainly in Asia and Africa, as some cities in regions such as Europe actually begin to shrink in population due to aging citizens and declining birth rates. In addition, Guangzhou, Shenzhen, and Chennai are all expected to meet the megacity definition by 2035. Specifically, it’s projected that Bangalore (India) and Lahore (Pakistan) will boot out Tianjin and Buenos Aires. Rankīy 2035, two new cities are expected to crack the top 20 list. Here’s a closer look at the top 20 most populous cities. In fact, it’s expected that Delhi’s population could surpass Tokyo’s by 2028. Indian and Chinese cities, on the other hand, will continue to grow rapidly in the coming years. While Tokyo is the world’s most populous city with 37,393,000 people, this number is leveling out due to declining birth rates and an aging population.
