Some context: Raymond Bernard Cattell (20 March 1905 - 2 February 1998) was a British and American psychologist, known for his psychometric research into intrapersonal psychological structure. His work also explored the basic dimensions of personality and temperament, the range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of abnormal personality, patterns of group syntality and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains. Cattell authored, co-authored, or edited almost 60 scholarly books, more than 500 research articles, and over 30 standardized psychometric tests, questionnaires, and rating scales. According to a widely cited ranking, Cattell was the 16th most eminent, 7th most cited in the scientific journal literature, and among the most productive, but controversial psychologists of the 20th century.
Rather than pursue a "univariate" research approach to psychology, studying the effect that a single variable (such as "dominance") might have on another variable (such as "decision-making"), Cattell pioneered the use of multivariate experimental psychology (the analysis of several variables simultaneously). He believed that behavioral dimensions were too complex and interactive to fully understand variables in isolation. The classical univariate approach required bringing the individual into an artificial laboratory situation and measuring the effect of one particular variable on another - also known as the "bivariate" approach, while the multivariate approach allowed psychologists to study the whole person and their unique combination of traits within a natural environmental context. Multivariate experimental research designs and multivariate statistical analyses allowed for the study of "real-life" situations (e.g., depression, divorce, loss) that could not be manipulated in an artificial laboratory environment.  Cattell applied multivariate research methods across several intrapersonal psychological domains: the trait constructs (both normal and abnormal) of personality, motivational or dynamic traits, emotional and mood states, as well as the diverse array of cognitive abilities. In each of these domains, he considered there must be a finite number of basic, unitary dimensions that could be identified empirically. He drew a comparison between these fundamental, underlying (source) traits and the basic dimensions of the physical world that were discovered and presented, for example, in the periodic table of chemical elements.  In 1960, Cattell organized and convened an international symposium to increase communication and cooperation among researchers who were using multivariate statistics to study human behavior. This resulted in the foundation of the Society of Multivariate Experimental Psychology (SMEP) and its flagship journal, Multivariate Behavioral Research. He brought many researchers from Europe, Asia, Africa, Australia, and South America to work in his lab at the University of Illinois. Many of his books involving multivariate experimental research were written in collaboration with notable colleagues.

Some context: Reba Nell McEntire was born March 28, 1955, in McAlester, Oklahoma, to Jacqueline (nee Smith; born November 6, 1926) and Clark Vincent McEntire (November 30, 1927 - October 23, 2014). Her father, and her grandfather, John Wesley McEntire (February 19, 1897 - February 13, 1976), were both champion steer ropers and her father was a World Champion Steer Roper three times (1957, 1958, and 1961). John McEntire was the son of Clark Stephen McEntire (September 10, 1855 - August 15, 1935) and Helen Florida McEntire (nee Brown; May 19, 1868 - May 16, 1947).
On October 21, 2014, it was announced that McEntire would be the inaugural signing for Big Machine's new imprint Nash Icon Music. She also disclosed that she was working on a new album, with 11 new songs.  Her first single for the new label, "Going Out Like That", was announced December 16, 2014 and was released on January 6, 2015. It served as the lead-off single to Love Somebody, McEntire's twenty-seventh studio album, released on April 14, 2015. Love Somebody debuted at No. 1 on the Billboard Top Country Albums--her twelfth number-one album on the chart--and No. 3 on Billboard 200, selling 62,469 copies in the U.S. The album has sold 171,600 copies in the U.S. as of October 5, 2015.  In 2016, McEntire was selected as one of thirty artists to perform on "Forever Country", a mash-up track of Take Me Home, Country Roads, On the Road Again and I Will Always Love You which celebrates 50 years of the CMA Awards.  McEntire released her third Christmas album My Kind of Christmas on September 2, 2016. The album was exclusively sold at Cracker Barrel and online. She also announced she would soon be selling her own line of clothing, home decor, jewelry and other things under the "Rockin' R by Reba" line also at Cracker Barrel.  McEntire was a guest judge on the July 13, 2016 episode of America's Got Talent. She used her golden buzzer, which she could only use once and allowed an act to go straight to the live shows, on contortionist Sofie Dossi.

Some context: Rudolf Nureyev was born on a Trans-Siberian train near Irkutsk, Siberia, Soviet Union, while his mother, Feride, was travelling to Vladivostok, where his father Hamit, a Red Army political commissar, was stationed. He was raised as the only son with three older sisters in a Tatar Muslim family. When his mother took Rudolf Nureyev and his sisters into a performance of the ballet Song of the Cranes, he fell in love with dance. As a child he was encouraged to dance in Bashkir folk performances and his precocity was soon noticed by teachers who encouraged him to train in Saint Petersburg.
When AIDS appeared in France's news around 1982, Nureyev took little notice. The dancer tested positive for HIV in 1984, but for several years he simply denied that anything was wrong with his health. However, by the late 1980s his diminished capabilities disappointed his admirers who had fond memories of his outstanding prowess and skill. Nureyev began a marked decline only in the summer of 1991 and entered the final phase of the disease in the spring of 1992.  In March 1992, living with advanced AIDS, he visited Kazan and appeared as a conductor in front of the audience at Musa Calil Tatar Academic Opera and Ballet Theater, which now presents the Rudolf Nureyev Festival in Tatarstan. Returning to Paris, with a high fever, he was admitted to the hospital Notre Dame du Perpetuel Secours in Levallois-Perret, a suburb northwest of Paris, and was operated on for pericarditis, an inflammation of the membranous sac around the heart. At that time, what inspired him to fight his illness was the hope that he could fulfill an invitation to conduct Prokofiev's Romeo and Juliet at an American Ballet Theatre benefit on 6 May 1992 at the Metropolitan Opera House in New York. He did so and was elated at the reception.  In July 1992, Nureyev showed renewed signs of pericarditis but determined to forswear further treatment. His last public appearance was on 8 October 1992, at the premiere at Palais Garnier of a new production of La Bayadere that he choreographed after Marius Petipa for the Paris Opera Ballet. Nureyev had managed to obtain a photocopy of the original score by Minkus when in Russia in 1989. The ballet was a personal triumph although the gravity of his condition was evident. The French Culture Minister, Jack Lang, presented him that evening on stage with France's highest cultural award, the Commandeur de l'Ordre des Arts et des Lettres.
