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 (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.

Start!

"Start!" is the eleventh UK single release by punk rock band, The Jam and their second number-one, following "Going Underground"/"Dreams of Children". Upon its release on 15 August 1980, it debuted at number three, and two weeks later reached number one for one week. Written by Paul Weller and produced by Vic Coppersmith-Heaven and The Jam, "Start!" was the lead single from the band's fifth album Sound Affects. The single's B-side is "Liza Radley".

"Start!" is based on both the main guitar riff and bass riff of The Beatles' 1966 song "Taxman" from the album Revolver, written by George Harrison. Likewise, The Jam's "Dreams of Children" had featured the same "Taxman" bassline, played then as a lead guitar riff.

The album version of the song runs at 2:30 and features trumpets in the final section. The single version, also featured on the "Snap!" compilation, is edited and slightly remixed, and omits the trumpets.

Other versions and sampling

Beastie Boys covered the song, which appears on their 1999 single, "Alive".
