Background: "Hit 'Em Up" is a diss song by rap artist 2Pac featuring his group the Outlawz. It is the B-side to the single "How Do U Want It", released on June 4, 1996. The song's lyrics contain vicious insults to several East Coast rappers, chief among them, Shakur's former friend turned rival, The Notorious B.I.G., also known as Biggie Smalls.
Context: Finishing the recording of the song, Shakur felt very positively about the track, saying the "song is going to be playing in every club., every country. Deejays are calling from everywhere, wanting to get a piece of this." "Hit 'Em Up" appeared first as a B-side, on the single "How Do U Want It", by Shakur featuring The Outlawz. On June 4, 1996 under the label Death Row Records, "Hit 'Em Up" was released on compact disc, 12-inch, and a 45 RPM. The original cover for the single had Puffy's head on a snake's body, and Biggie's head on a pig's. It also appeared posthumously on several compilations, including the 2004 release of Shakur's last recorded live performance, Live at the House of Blues. "Hit 'Em Up" was also remixed on Nu-Mixx Klazzics. Upon its release, "Hit 'Em Up" received frequent radio airplay, which was attributed to the public interest in the ongoing feud and radio stations' desire to garner high ratings. However, some radio stations, such as the Los Angeles-based KPWR, refused to play it. The follow-up to "Hit 'Em Up" was the song "Bomb First (My Second Reply)". "Hit 'Em Up" has been called "controversial," "infamous," "disturbing," and "brutal." Shakur's insults against virtually the entire East Coast scene of rappers were said to be ferocious. The song, along with "Dear Mama," has been viewed as one of Shakur's songs that resonated with and was spoken of the most by young people. Some felt that "Hit 'Em Up" showcased Shakur ranting and raving like a fool, and J.R. Reynolds of Billboard called it horrendous, noting that Shakur revealed his true colors upon recording the song. He also went on to say that although sympathetic to the shooting, "Hit 'Em Up" had "fan[ned] the flames of hatred ...and affect[ed] an entire black culture's psyche"; he called the song "repugnant and unacceptable." Among associates of Shakur, it was called a "bad-luck song." Los Angeles radio director Bruce St. James called the song "the be-all, end-all, curse-word, dirty-lyric, violent song of all time." Game's manager has called it the best diss record. Documentary filmmaker Carl Weston believed that "most people in Biggie's shoes would have wanted to at least hurt Tupac" in a Spin magazine interview. Among musicians, the song drew criticism from singer Dionne Warwick, and disapproval from fellow rappers Kool Moe Dee and Chuck D, as written in their book There's a God on the Mic: The True 50 Greatest MCs. They felt that although Shakur was one of the most substantive rappers of that period, he had gone too far with "Hit 'Em Up," causing some of Shakur's fans to turn on him, according to the two rappers.
Question: Was there any controversy?
Answer: However, some radio stations, such as the Los Angeles-based KPWR, refused to play it.

Background: Alice Hamilton (February 27, 1869 - September 22, 1970) was an American physician, research scientist, and author who is best known as a leading expert in the field of occupational health and a pioneer in the field of industrial toxicology. She was also the first woman appointed to the faculty of Harvard University. Her scientific research focused on the study of occupational illnesses and the dangerous effects of industrial metals and chemical compounds. In addition to her scientific work, Hamilton was a social-welfare reformer, humanitarian, peace activist, and a resident-volunteer at Hull House in Chicago.
Context: Hamilton began her long career in public health and workplace safety in 1910, when Illinois governor Charles S. Deneen appointed her as a medical investor to the newly-formed Illinois Commission on Occupational Diseases. Hamilton lead the commission's investigations, which focused on industrial poisons such as lead and other toxins. She also authored the "Illinois Survey," the commission's report that documented its findings of industrial processes that exposed workers to lead poisoning and other illnesses. The commission's efforts resulted in the passage of the first workers' compensation laws in Illinois in 1911, in Indiana in 1915, and occupational disease laws in other states. The new laws required employers to take safety precautions to protect workers. By 1916 Hamilton had become America's leading authority on lead poisoning. For the next decade she investigated a range of issues for a variety of state and federal health committees. Hamilton focused her explorations on occupational toxic disorders, examining the effects of substances such as aniline dyes, carbon monoxide, mercury, tetraethyl lead, radium, benzene, carbon disulfide and hydrogen sulfide gases. In 1925, at a Public Health Service conference on the use of lead in gasoline, she testified against the use of lead and warned of the danger it posed to people and the environment. Nevertheless, leaded gasoline was allowed. The EPA in 1988 estimated that over the previous 60 years that 68 million children suffered high toxic exposure to lead from leaded fuels. Her work on the manufacture of white lead and lead oxide, as a special investigator for the U.S. Bureau of Labor Statistics, is considered a "landmark study". Relying primarily on "shoe leather epidemiology" (her process of making personal visits to factories, conducting interviews with workers, and compiling details of diagnosed poisoning cases) and the emerging laboratory science of toxicology, Hamilton pioneered occupational epidemiology and industrial hygiene. She also created the specialized field of industrial medicine in the United States. Her findings were scientifically persuasive and influenced sweeping health reforms that changed laws and general practice to improve the health of workers. During World War I, the US Army tasked her with solving a mysterious ailment striking workers at a munitions plant in New Jersey. She led a team that included George Minot, a Professor at Harvard Medical School. She deduced that the workers were being sickened through contact with the explosive trinitrotoluene (TNT). Her recommendations that workers wear protective clothing that should be removed and washed at the end of each shift solved the problem. Hamilton's best-known research included her studies on carbon monoxide poisoning among American steelworkers, mercury poisoning of hatters, and "a debilitating hand condition developed by workers using jackhammers." At the request of the U.S. Department of Labor, she also investigated industries involved in developing high explosives, "spastic anemia known as 'dead fingers'" among Bedford, Indiana, limestone cutters, and the "unusually high incidence of pulmonary tuberculosis" among tombstone carvers working in the granite mills of Quincy, Massachusetts, and Barre, Vermont. Hamilton was also a member of the Committee for the Scientific Investigation of the Mortality from Tuberculosis in Dusty Trades, whose efforts "laid the groundwork for further studies and eventual widespread reform in the industry."
