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.

Trek (band)

Trek is a Russian rock band formed in Khabarovsk, Soviet Russia, in 1977.

History

The group was formed in 1977.

The constant structure was formed in 1980. In 1982 they published their first album «Flying for line».

In 1991 the band plays at a Soviet-Japanese-American festival in Vladivostok.

In 1995 the group publishes the CD «Blessed to Feel», the first CD of a Far Eastern rock group. There was a considerable number of groups by then in Khabarovsk and the band "Track" decided to start rock club "Roxy" on June, 24th, 1995.

In 1996 "Track" performs at the Russian-American festival in Vladivostok "Vladi-ROCKstok-96". There was a manager of the band "Nazareth" present at that festival. He invited the "Track" for a joint concert with «Nazareth» in Vladivostok. Tours «Nazareth» coincide with Dan McCafferty's 50 anniversary and "Track" also was officially invited to celebrating of anniversary. McCafferty said in exclusive interview for TVA: «"Trek" is the best that I heard in Russia». But then "Trek" broke up.

Star Trek: The Original Series

Star Trek is an American science fiction television series created by Gene Roddenberry that follows the adventures of the starship USS Enterprise (NCC-1701) and its crew. It later acquired the retronym of Star Trek: The Original Series (Star Trek: TOS or simply TOS) to distinguish the show within the media franchise that it began.

The show is set in the Milky Way galaxy, roughly during the 2260s. The ship and crew are led by Captain James T. Kirk (William Shatner), first officer and science officer Spock (Leonard Nimoy), and chief medical officer Leonard McCoy (DeForest Kelley). Shatner's voice-over introduction during each episode's opening credits stated the starship's purpose:

The series was produced from September 1966–December 1967 by Desilu Productions, and by Paramount Television from January 1968–June 1969. Star Trek aired on NBC from September 8, 1966 to June 3, 1969 and from September 6 on Canada's CTV network. Star Trek's Nielsen ratings while on NBC were low, and the network canceled it after three seasons and 79 episodes. Several years later, the series became a bona fide hit in broadcast syndication, remaining so throughout the 1970s, achieving cult classic status and a developing influence on popular culture. Star Trek eventually spawned a franchise, consisting of five additional television series, twelve feature films, numerous books, games, toys, and is now widely considered one of the most popular and influential television series of all time.

Acid (computer virus)

Acid is a computer virus which infects .COM and .EXE files including command.com. Each time an infected file is executed, Acid infects all of the .EXE files in the current directory. Later, if an infected file is executed, it infects the .COM files in the current directory. Programs infected with Acid will have had the first 792 bytes of the host program overwritten with Acid's own code. There will be no file length increase unless the original host program was smaller than 792 bytes, in which case it will become 792 bytes in length. The program's date and time in the DOS disk directory listing will not be altered.

The following text strings are found in infected files:
