Question: Nobuo Uematsu (Zhi Song  Shen Fu , Uematsu Nobuo, born March 21, 1959) is a Japanese video game composer, best known for scoring most of the titles in the Final Fantasy series by Square Enix. He is considered to be one of the most well known composers in the video game industry. Sometimes referred to as the "Beethoven of video games music", he appeared five times in the top 20 of the annual Classic FM Hall of Fame. Uematsu, a self-taught musician, began playing the piano at the age of twelve, with English singer-songwriter Elton John as his biggest influence.

Uematsu joined Square in 1985, and composed the soundtrack to Cruise Chaser Blassty in 1986, his first. While working at Square, he met Hironobu Sakaguchi, who asked him if he wanted to create music for some of his games, which Uematsu agreed to. For the next year, he created music for a number of games which did not achieve widespread success, including titles like Genesis and Alpha. In 1987, Uematsu and Sakaguchi collaborated on what was originally to be Sakaguchi's last contribution for Square, Final Fantasy, a game that turned out to be a huge success.  Final Fantasy's popularity sparked Uematsu's career in video game music, and he would go on to compose music for over 30 titles, most prominently the subsequent games in the Final Fantasy series. He scored the first installment in the SaGa series, The Final Fantasy Legend, in 1989. For the second game in the series, Final Fantasy Legend II he was assisted by Kenji Ito. In late 1994, Uematsu signed on to finish the soundtrack for the critically acclaimed title Chrono Trigger after the game's composer, Yasunori Mitsuda, contracted peptic ulcers. In 1996, he co-composed the soundtrack to Front Mission: Gun Hazard, and created the entire score for DynamiTracer. He also created music for three of the games in the Hanjuku Hero series.  Outside video games, he has composed the main theme for the 2000 animated film Ah! My Goddess: The Movie and co-composed the anime Final Fantasy: Unlimited (2001) with Final Fantasy orchestrator Shiro Hamaguchi. He also inspired the Ten Plants concept albums, and released a solo album in 1994, entitled Phantasmagoria. Feeling gradually more dissatisfied and uninspired, Uematsu requested the assistance of composers Masashi Hamauzu and Junya Nakano for the score to Final Fantasy X in 2001. This marked the first time that Uematsu did not compose an entire main-series Final Fantasy soundtrack. For Final Fantasy XI from 2002, he was joined by Naoshi Mizuta, who composed the majority of the soundtrack, and Kumi Tanioka; Uematsu was responsible for only eleven tracks. In 2003, he assisted Hitoshi Sakimoto in scoring Final Fantasy Tactics Advance by providing the main theme.  In 2002, fellow Square colleagues Kenichiro Fukui and Tsuyoshi Sekito asked Uematsu to join them in forming a rock band that focused on reinterpreting and expanding on Uematsu's compositions. He declined their offer at first because he was too busy with work; however, after agreeing to perform with Fukui and Sekito in a live performance as a keyboardist, he decided to join them in making a band. Another employee at Square, Mr. Matsushita, chose the name The Black Mages for their band. In 2003, Keiji Kawamori, Arata Hanyuda, and Michio Okamiya also joined the band. The Black Mages released three studio albums, and appeared at several concerts to promote their albums.

Answer: The Black Mages released three studio albums,


Question: 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.

Cattell noted that in the hard sciences such as chemistry, physics, astronomy, as well as in medical science, unsubstantiated theories were historically widespread until new instruments were developed to improve scientific observation and measurement. In the 1920s, Cattell worked with Charles Spearman who was developing the new statistical technique of factor analysis in his effort to understand the basic dimensions and structure of human abilities. Factor analysis became a powerful tool to help uncover the basic dimensions underlying a confusing array of surface variables within a particular domain.  Factor analysis was built upon the earlier development of the correlation coefficient, which provides a numerical estimate of the degree to which variables are "co-related". For example, if "frequency of exercise" and "blood pressure level" were measured on a large group of people, then intercorrelating these two variables would provide a quantitative estimate of the degree to which "exercise" and "blood pressure" are directly related to each other. Factor analysis performs complex calculations on the correlation coefficients among the variables within a particular domain (such as cognitive ability or personality trait constructs) to determine the basic, unitary factors underlying the particular domain.  While working at the University of London with Spearman exploring the number and nature of human abilities, Cattell postulated that factor analysis could be applied to other areas beyond the domain of abilities. In particular, Cattell was interested in exploring the basic taxonomic dimensions and structure of human personality. He believed that if exploratory factor analysis were applied to a wide range of measures of interpersonal functioning, the basic dimensions within the domain of social behavior could be identified. Thus, factor analysis could be used to discover the fundamental dimensions underlying the large number of surface behaviors, thereby facilitating more effective research.  As noted above, Cattell made many important innovative contributions to factor analytic methodology, including the Scree Test to estimate the optimal number of factors to extract, the "Procrustes" oblique rotation strategy, the Coefficient of Profile Similarity, P-technique factor analysis, dR-technique factor analysis, the Taxonome program, as well the Rotoplot program for attaining maximum simple structure solutions. In addition, many eminent researchers received their grounding in factor analytic methodology under the guidance of Cattell, including Richard Gorsuch, an authority on exploratory factor analytic methods.

Using a quote from the above article, answer the following question: What are the purpose of the unitary factors?
HHHHHH
Answer:
if exploratory factor analysis were applied to a wide range of measures of interpersonal functioning, the basic dimensions within the domain of social behavior could be identified.
