Social network analysis

Social network analysis (SNA) is the process of investigating social structures through the use of network and graph theories. It characterizes networked structures in terms of nodes (individual actors, people, or things within the network) and the ties or edges (relationships or interactions) that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, friendship and acquaintance networks, kinship, disease transmission,and sexual relationships. These networks are often visualized through sociograms in which nodes are represented as points and ties are represented as lines.

Social network analysis has emerged as a key technique in modern sociology. It has also gained a significant following in anthropology, biology, communication studies, economics, geography, history, information science, organizational studies, political science, social psychology, development studies, and sociolinguistics and is now commonly available as a consumer tool.

Cascade, Atlanta

Cascade in Atlanta may refer to:

Cascade (juggling)

In toss juggling, a cascade is the simplest juggling pattern achievable with an odd number of props. The simplest juggling pattern is the three-ball cascade. This is therefore the first pattern that most jugglers learn. "Balls or other props follow a horizontal figure-eight pattern above the hands." In siteswap, each throw in a cascade is notated using the number of balls; thus a three ball cascade is "3".

Number of props

Three-ball

For the three-ball cascade the juggler starts with two balls in one hand and the third ball in the other hand. One ball is thrown from the first hand in an arc to the other hand. Before catching this ball the juggler must throw the ball in the receiving hand, in a similar arc, to the first hand. The pattern continues in this manner with each hand in turn throwing one ball and catching another.

All balls are caught on the outside of the pattern (on the far left and right) and thrown from closer to the middle of the pattern. The hand moves toward the middle to throw, and back towards the outside to catch the next object. Because the hands must move up and down when throwing and catching, putting this movement together causes the left hand to move in a counterclockwise motion, and the right hand to move in a clockwise motion.

Crazy (Seal song)

"Crazy" is a song originated by English soul artist Seal, who wrote its lyrics and jointly composed its music in collaboration with producer Guy Sigsworth. The song was produced by Trevor Horn for Seal's debut album Seal (1991). Released as his debut single, "Crazy" became one of Seal's biggest hits, reaching the top five in the United Kingdom while becoming his first top ten single in the United States. It has since been interpreted by several artists, including Alanis Morissette, whose version was released as a single from her album The Collection (2005).

Background and composition

Seal wrote "Crazy" in 1990 inspired by the fall of the Berlin Wall in 1990 and the Tiananmen Square Massacre in 1989. In 2015, Seal said of the song's conception in 1990: "I felt the cycle had reached its apex. I felt the world changing and I felt profound things happening."

According to the song's producer Trevor Horn, "Crazy" was made over the course of two months: "Crazy wasn't an easy record to make, because we were aiming high".

Because of You (Ne-Yo album)

Because of You is the second studio album by American recording artist Ne-Yo, released on April 25, 2007 by Def Jam Recordings in the United States. It features guest contributions from rapper Jay-Z on "Crazy" and singer Jennifer Hudson on "Leaving Tonight". Because of You debuted at number one on the Billboard 200 and Top R&B/Hip-Hop Albums charts, selling over 250,000 copies in its first week. Upon its release, the album received generally positive reviews from most music critics, based on an aggregate score of 74/100 from Metacritic. It won a Grammy Award for Best Contemporary R&B Album at the 2008 Grammy Awards.

Critical reception

The album has drawn mainly positive reviews, with Entertainment Weekly magazine noting, "Indeed, the album is an unmistakable attempt to channel [Michael Jackson's early work such as "Off the Wall"]...and the effort often pays off beautifully...Ne-Yo's lithe falsetto puts the many others who've been labeled Jackson-esque to shame." PopMatters.com called the album "a masterpiece of a record" and praised the title track's blend of "upbeat modern-day funk tempo, beautifully melodic backdrop and love-sick (in a good way) vocals...[it's] the perfect lead single off an album that is filled with number-one hits".Slant Magazine also compared the album's sensual ballads to Janet Jackson.

Crazy (Willie Nelson song)

"Crazy" is a ballad composed by Willie Nelson. It has been recorded by several artists, most notably by Patsy Cline, whose version was a #2 country hit in 1962.

Partly due to the genre-blending nature of the song, it has been covered by dozens of artists in several genres over the years; nevertheless, the song remains inextricably linked with Cline. Nelson's own version appears on his 1962 debut album ...And Then I Wrote.

Origin

With some help from a friend named Oliver English, Nelson wrote the song in early 1961; at the time he was a journeyman singer-songwriter who had written several hits for other artists but had not yet had a significant recording of his own. Nelson originally wrote the song for country singer Billy Walker who turned it down for the same reason Roy Drusky turned down "I Fall to Pieces" the previous year - that it was "a girl's song". The song's eventual success helped launch Nelson as a performer as well as a songwriter.

Musically the song is a jazz-pop ballad with country overtones and a complex melody. The lyrics describe the singer's state of bemusement at the singer's own helpless love for the object of his affection.
