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 Range

The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).

The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004-2008.

Cascade (computer virus)

The Cascade virus is a prominent computer virus that was a resident written in assembly, and it was widespread in the 1980s and early 1990s. It infected .COM files and had the effect of making text on the screen fall down and form a heap in the bottom of the screen. It was notable for using an encryption algorithm to avoid being detected. However one could see that infected files had their size increased by 1701 or 1704 bytes. In response, IBM developed its own anti-virus software.

The virus has a number of variants. Cascade-17Y4, which is reported to have originated in Yugoslavia is almost identical to the most common 1704 byte variant. One byte has been changed, probably due to a random "mutation". This, however, has resulted in a "bug" in the virus. Another mutated variant is also known - it infects the same file over and over.

Medway

Medway is a conurbation and unitary authority in South East England. The unitary authority was formed in 1998 when the City of Rochester-upon-Medway amalgamated with Gillingham Borough Council and part of Kent County Council to form Medway Council, a unitary authority independent of Kent County Council.

It is colloquially known as the Medway Towns. Over half of the unitary authority area is parished and rural in nature. Because of its strategic location by the major crossing of the River Medway, it has made a wide and historically significant contribution to Kent, and to England, dating back thousands of years, as evident in the siting of Watling Street by the Romans and by the Norman Rochester Castle, Rochester Cathedral (the second oldest in Britain) and the Chatham naval dockyard and its associated defences.

The main towns in the conurbation are (from west to east): Strood, Rochester, Chatham, Gillingham, and Rainham. Many smaller towns and villages such as Frindsbury, Brompton, Walderslade, Luton, Wigmore etc., lie within the conurbation. Outside the urban area, the villages retain parish councils. Cuxton, Halling and Wouldham are in the Medway Gap region to the south of Rochester and Strood. Hoo St Werburgh, Cliffe, High Halstow, St Mary Hoo, Allhallows, Stoke and Grain are on the Hoo Peninsula to the north. Frindsbury Extra including Upnor borders Strood.

Medway (Mount Holly, South Carolina)

Medway or the Medway Plantation is a plantation in Mount Holly, South Carolina within Berkeley County, South Carolina. It is about 2 mi (3.2 km) east of U.S. Route 52 from the unincorporated community of Mount Holly, which is directly north of Goose Creek, South Carolina. It was named to the National Register of Historic Places on July 16, 1970.

History

Jan Van Arrsens, the Seigneur of Wernhaut (also "Weirnhoudt"), led a small group of settlers from Holland to the province of Carolina around 1686. He built his house on the Back River, which was formerly called the "Meadway" or "Medway" and is a tributary of the Cooper River. Van Arrsens died soon after his arrival and was buried at Medway.

His widow, Sabrina de Vignon, married Landgrave Thomas Smith around 1687, which made Smith one of the wealthiest men in the Province. Sabrina Smith died in 1689 and was buried at Medway. Thomas Smith was appointed governor of the Province of Carolina in 1693. He died in 1694 and was also buried at Medway.

Medway, Massachusetts

Medway is a town in Norfolk County, Massachusetts, United States with a population of about 13,000.

History

Medway was first settled in 1657 and was officially incorporated in 1713. At that time, Medway began as a farming community of two hundred thirty-three. It was not long before the water power of the Charles River and Chicken Brook stimulated the formation of cotton and paper mills, straw and boot factories, and a variety of cottage industries. Medway demonstrates the central importance of the Charles River and the thriving town that grew alongside it. Today, the one-room schoolhouses are gone and the country stores have moved to the mall, but the open town meetings continue.

After nearby Medfield was established as a town in 1651, an increasing number of newcomers settled on the land west of the Charles River. By 1712, this settlement west of the Charles had grown large enough to petition the Massachusetts General Court for the creation of a separate new town. That petition was granted, and the town of Medway incorporated on October 25, 1713. At its founding, and for 170 years afterward, the town of Medway included the land that is now Millis. Eventually, the eastern section of the town, known as East Medway, separated in 1885 to form the town of Millis, and Medway assumed the shape it has today.
