Alexander v. Holmes County Board of Education, 396 U.S. 19 (1969) , was a United States Supreme Court case in which the Court ordered immediate desegregation of public schools in the American South.
 It followed 15 years of delays to integrate by most Southern school boards after the Court's ruling in "Brown v. Board of Education" (1954) that segregated public schools were unconstitutional.
Xi Gang (); 1746-1803 was a renowned seal carver and painter in Qing Dynasty.
 He was born in Qiántáng (钱塘, present day Hangzhou).
 His style name was Chunzhang (纯章) and his pseudonym was Tiesheng (铁生).
 Other names include Hezhusheng (鹤注生) and Mengquan Waishi (蒙泉 外史).
 His specialty was in painting landscapes.
 His seal carving method was similar to that of Ding Jing (丁敬) (with whom he co-founded the Zhe School of carving), though somewhat cleaner and sharper.
 His style is representative of the Southern School.
 He was also talented in prose and calligraphy.
The Kingdom of Mysore (1399–1950) was founded by Yaduraya in 1399 as a feudatory of the Vijayanagara Empire and became an independent kingdom in the early 17th century, after the decline of the Vijayanagara Empire.
 Many musicians and composers have presumably adorned the courts of the Mysore kings from Yaduraya's time, furthering the "Dakshinadi" school (southern school) of music that had developed in earlier centuries.
 However, records are only available from the time of King Ranadheera Kanteerava Narasaraja Wodeyar (1638).
 Musical treatises surviving from this time, though, provide ample information on the music, musical instruments, the types of compositions, the "raga" (melodies) and the "tala" (rhythms) used.
 Though all the Mysore kings patronised music, the golden age of Carnatic music was considered to be during the reigns of Kings Krishnaraja Wodeyar III (1794–1868), Chamaraja Wodeyar IX (1862–1894), Krishnaraja Wodeyar IV (1884–1940) and Jaya Chamaraja Wodeyar (1919–1974).
 The reign of Krishnaraja Wodeyar IV is regarded as particularly important in musical terms.
Dai Jin (; 1388-1462) was a Chinese artist best known for being the founder of the Zhe School of Ming dynasty painting.
The University of Minnesota Waseca (UMW) was a two-year technical college specializing in agriculture and located in Waseca, in the U.S. state of Minnesota.
 A part of the University of Minnesota system, it operated from 1971 to 1992 and served nearly 20,000 students during that time.
 Their mascot was the "Ramus" the ram.
 It maintained a college radio station with the call letters KOWO.
 Its campus was previously an agricultural boarding high school known as the Southern School of Agriculture.
The Southern School (南宗画, pinyin: "nanzhonghua") of Chinese painting, often called "literati painting" (文人画, "wenrenhua"), is a term used to denote art and artists which stand in opposition to the formal Northern School of painting.
 The distinction is not geographic, but relates to the style and contents of the works, and to some extent to the position of the artist.
 Typically, where professional, formal painters were classified as Northern School, scholar-bureaucrats who had either retired from the professional world or who were never a part of it constituted the Southern School.
The southern school whiting, "Sillago bassensis", (also known as the silver whiting or trawl whiting) is a common species of coastal marine fish of the smelt-whiting family that inhabits the south and south-west coasts of Australia.
 Its distribution overlaps a number of other common sillaginids, with careful observation of anatomical features occasionally needed to distinguish between species.
 The southern school whiting is closely related to the eastern school whiting, "Sillago flindersi", and initially were thought to be all one species.
 The species inhabits both shallow inshore sandy waters, as well as deeper offshore waters, with a transition of habitats occurring with increasing age.
 It is a predatory fish, taking a variety of crustaceans, polychaetes and bivalves as prey.
 It reaches sexual maturity at three years of age, and spawns multiple times between December and April.
 The southern school whiting is commonly caught by commercial and recreational fishermen, often while fishing for related species, especially the sought after King George whiting.
 The species is marketed fresh in southern Australia.
Ma Yuan (c. 1160–65 – 1225) was a Chinese painter of the Song Dynasty.
 His works, together with that of Xia Gui, formed the basis of the so-called Ma-Xia (馬夏) school of painting, and are considered among the finest from the period.
 His works has inspired both Chinese artists of the Zhe School, as well as the great early Japanese painters Shūbun and Sesshū.
The Ming dynasty was the ruling dynasty of China – then known as the Empire of the Great Ming – for 276 years (1368–1644) following the collapse of the Mongol-led Yuan dynasty.
 The Ming, described by Edwin O. Reischauer, John K. Fairbank and Albert M. Craig as "one of the greatest eras of orderly government and social stability in human history", was the last imperial dynasty in China ruled by ethnic Han Chinese.
 Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the Shun dynasty, soon replaced by the Manchu-led Qing dynasty), regimes loyal to the Ming throne – collectively called the Southern Ming – survived until 1683.
The Zhe School (浙派) was a school of painters and was part of the Southern School, which thrived during the Ming dynasty.
 The school was led by Dai Jin, traditionally considered its founder.
 The "Zhe" of the name refers to Dai Jin's home province - Zhejiang.
 The school was not a school in the proper sense of the word in that the painters did not formulate a new distinctive style, preferring instead to further the style of the Southern Song, specializing in decorative and large paintings.
 Instead the school was identified by the formal, academic and conservative outlook, being a revival in the early Ming Dynasty of the Ma-Xia (Ma Yuan 馬遠, Xia Gui 夏珪), 'academic', style of painting landscapes of the Southern Song.
