Some context: Lillian Evelyn Moller Gilbreth (May 24, 1878 - January 2, 1972) was an American psychologist, industrial engineer, consultant, and educator who was an early pioneer in applying psychology to time-and-motion studies. She was described in the 1940s as "a genius in the art of living." Gilbreth, one of the first female engineers to earn a Ph.D., is considered to be the first industrial/organizational psychologist.
For more than forty years, Gilbreth's career combined psychology with the study of scientific management and engineering. She also included her perspectives as a wife and mother in her research, writing, and consulting work. Gilbreth became a pioneer in what is now known as Industrial and organizational psychology. She helped industrial engineers recognized the importance of the psychological dimensions of work. In addition, she became the first American engineer ever to create a synthesis of psychology and scientific management. (Gilbreth introduced the concept of using psychology to study management at the Dartmouth College Conference on Scientific Management in 1911.) In addition to jointly running Gilbreth Incorporated, their business and engineering consulting firm, Lillian and Frank wrote numerous publications as sole authors, as well as co-authoring multiple books and more than fifty papers on a variety of scientific topics. However, in their joint publications Lillian was not always named as a co-author, possibly due to publishers' concerns about a female writer. Althhough her credentials included a doctorate in psychology, she is less frequently credited in their joing publications than her husband, who did not attend college. The Gilbreths were certain that the revolutionary ideas of Frederick Winslow Taylor would be neither easy to implement nor sufficient; their implementation would require hard work by engineers and psychologists to make them successful. The Gilbreths also believed that scientific management as formulated by Taylor fell short when it came to managing the human element on the shop floor. The Gilbreths helped formulate a constructive critique of Taylorism; this critique had the support of other successful managers.

Question: Ashanti Shequoiya Douglas was born on October 13, 1980, in Glen Cove, New York. Her mother, Tina Douglas, is a former dance teacher, and her father, Ken-Kaide Thomas Douglas, is a former singer. Her mother named her after the Ashanti Empire in Ghana; in this nation, women had power and influence, and Tina wanted Ashanti to follow that model. Her grandfather, James, was a civil rights activist who associated with Martin Luther King, Jr. in the 1960s.

Before Concrete Rose was released, Ashanti did some major promotion for her single "Only U", when she premiered it at the 2004 Vibe Music Awards. She featured on "Wonderful"--with Ja Rule and R. Kelly--that year, which peaked at number five in the U.S. and at number one in the UK. In December 2004, Ashanti released her third studio album, Concrete Rose, the title of which took on Tupac Shakur's pseudonym "The Rose That Grew from Concrete". The album debuted at number seven in the U.S., with first-week sales of 254,000 copies, and eventually became her third platinum certified album. The first single, "Only U", reached number thirteen on the Billboard Hot 100 and became her biggest hit in the United Kingdom, peaking at number two. A second single, the ballad "Don't Let Them", garnered little chart success after Def Jam refused to fund a music video due to Irv Gotti's legal troubles during his money laundering trial. The single was released only in the U.S., where it failed to chart, and the UK, where it reached the lower end of the top forty. After the release of Concrete Rose, Ashanti released the DVD Ashanti: The Making of a Star, which was available only for a limited time. The deluxe DVD includes exclusive photo and video shoot footage, music from the albums Ashanti, Chapter II and Concrete Rose, special concert footage, unreleased childhood school performances and behind-the-scenes interviews with family, friends, and fans. In 2005, Ashanti focused more on her acting career, making her feature film acting debut in the film Coach Carter alongside Samuel L. Jackson, as well as starring as Dorothy Gale in the made-for-television film The Muppets' Wizard of Oz, which pulled in nearly 8 million viewers when it premiered. In Coach Carter, she played a pregnant teenager named Kyra who has to decide whether or not to abort her unborn child. The movie opened at number-one at the U.S. box office, eventually grossing $67 million domestically. Later in 2005, Ashanti was invited to Oprah Winfrey's Legends Ball, which honored some of the most influential and legendary African American women of the twentieth century in the fields of art, entertainment, and civil rights. In December 2005, Ashanti released a remix album of Concrete Rose titled Collectables by Ashanti. The album was an opportunity for her to fulfill her contract with Def Jam (and have the option of working with another label), and did not fare well on the charts. In 2006, she starred in the teen comedy John Tucker Must Die, which opened and peaked at number three at the U.S. box office (competing with Pirates of the Caribbean: Dead Man's Chest and Miami Vice) and grossed $68,818,076 worldwide. In 2007, she played a supporting role in the action film Resident Evil: Extinction (2007).

Some context: Christopher Houston Carson (December 24, 1809 - May 23, 1868), better known as Kit Carson, was an American frontiersman. He was a mountain man (fur trapper), wilderness guide, Indian agent, and U.S. Army officer. Carson became a frontier legend in his own lifetime via biographies and news articles. Exaggerated versions of his exploits were the subject of dime novels.
Carson wanted to take a winter break from the campaign. Major General Carleton refused. Kit was ordered to invade the Canyon de Chelly. It was here that many Navajos had taken refuge. Historian David Roberts writes, "Carson's sweep through the Canyon de Chelly in the winter of 1863-1864 would prove to be the decisive action in the Campaign." The Canyon de Chelly was a sacred place for the Navajo. They believed that it would now be their strongest sanctuary. Three hundred Navajo took refuge on the canyon rim at a place called Fortress Rock. They resisted Carson's invasion by building rope ladders and bridges, lowering water pots into a stream, and keeping quiet and out of sight. These three hundred Navajo survived the invasion. In January 1864, Carson swept through the 35-mile (56 km) Canyon with his forces. The thousands of peach trees in the canyon were cut down. Few Navajo were killed or captured. Carson's invasion, however, proved to the Navajo that the United States could invade their country at any time. Many Navajo surrendered at Fort Canby. By March 1864, there were 3,000 refugees at Fort Canby. An additional 5,000 arrived in the camp. They were suffering from the intense cold and hunger. Carson asked for supplies to feed and clothe them. The thousands of Navajo were led to Bosque Redondo. Many died along the way. Stragglers in the rear were shot and killed. In Navajo history, this horrific trek is known as Long Walk of the Navajo. By 1866, reports indicated that Bosque Redondo was a complete failure. Major Carleton was fired. Congress started investigations. In 1868, a treaty was signed, and the Navajo were allowed to return to their homeland. Bosque Redondo was closed.
