Alex Bavelas
Alexander Bavelas (December 26, 1913 – August 16, 1993) was an American psychosociologist credited as the first to define closeness centrality. His work was influential in using mathematics in developing the concept of centralization and in formalizing fundamental concepts of network structure. University of Iowa As one of Kurt Lewin's first graduate students, Bavelas went to University of Iowa from Springfield College trained on group work. He suggested to Lewin a method of training people to be democratic, which would become the germ of extending autocracy-democracy studies to the field of industrial relations. At Lewin's suggestion, Bavelas sought to directly apply small group dynamics theory to labor-management relations by conducting small-group experiments at the Harwood Manufacturing Company in Virginia, known as Harwood research. In implementing a program of collaborative research in Harwood, he created and developed the `Echo approach' in the early 1940s. From 1 ...

Chicopee, Massachusetts
Chicopee ( ) is a city located on the Connecticut River in Hampden County, Massachusetts, United States. As of the 2020 census, the city had a population of 55,560, making it the second-largest city in Western Massachusetts after Springfield. Chicopee is part of the Springfield, Massachusetts Metropolitan Statistical Area. The communities of Chicopee Center (Cabotville), Chicopee Falls, Willimansett, Fairview, Aldenville, Burnett Road, Smith Highlands and Westover are located within the city. One of the ventures of the Boston Associates, Chicopee is a city built around several smaller former mill communities on its namesake, the Chicopee River. During the 19th century, the city was home to the first American producer of friction matches as well as a variety of other industries, including the Ames Manufacturing Company, an early pioneer in machining lathes, building upon the work of Springfield's Thomas Blanchard, and the largest producer of swords and cutlasses for the Union A ...

Closeness Centrality
In a connected graph, closeness centrality (or closeness) of a node is a measure of centrality in a network, calculated as the reciprocal of the sum of the length of the shortest paths between the node and all other nodes in the graph. Thus, the more central a node is, the ''closer'' it is to all other nodes. Closeness was defined by Bavelas (1950) as the reciprocal of the farness, that is: : C_B(x)= \frac. where d(y,x) is the distance (length of the shortest path) between vertices x and y. This unnormalised version of closeness is sometimes known as status When speaking of closeness centrality, people usually refer to its normalized form which represents the average length of the shortest paths instead of their sum. It is generally given by the previous formula multiplied by N-1, where N is the number of nodes in the graph resulting in: : C(x)= \frac. The normalization of closeness simplifies the comparison of nodes in graphs of different sizes. For large graphs, the minus one ...

Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...

Times Colonist
The ''Times Colonist'' is an English-language daily newspaper in Victoria, British Columbia, Canada. It was formed by the Sept. 2, 1980 merger of the ''Victoria Daily Times'', established in 1884, and the ''British Colonist'' (later the ''Daily Colonist''), established in 1858 by Amor De Cosmos who was later British Columbia's second Premier. The ''British Colonist'' was B.C.'s first paper "of any permanence". De Cosmos was the editor until 1866 when D.W. Higgins took over — he would remain in the role for the next twenty years. Local news receives the greatest prominence in the ''Times Colonist''. Stories and photographs about Greater Victoria are often featured on the front page. The newspaper also has national and international stories, plus sections covering the arts, sports, and business. The Times Colonist has a website as well as an e-edition, which offers a digital replica of the printed pages. According to News Media Canada, the Times Colonist saw an average daily circu ...

Leon Festinger
Leon Festinger (8 May 1919 – 11 February 1989) was an American social psychologist who originated the theory of cognitive dissonance and social comparison theory. The rejection of the previously dominant behaviorist view of social psychology by demonstrating the inadequacy of stimulus-response conditioning accounts of human behavior is largely attributed to his theories and research. Festinger is also credited with advancing the use of laboratory experimentation in social psychology, although he simultaneously stressed the importance of studying real-life situations, a principle he practiced when personally infiltrating a doomsday cult. He is also known in social network theory for the proximity effect (or propinquity). Festinger studied psychology under Kurt Lewin, an important figure in modern social psychology, at the University of Iowa, graduating in 1941; however, he did not develop an interest in social psychology until after joining the faculty at Lewin's Research Cente ...

Douglas McGregor
Douglas Murray McGregor (September 6, 1906 – October 1, 1964) was an American management professor at the MIT Sloan School of Management and president of Antioch College from 1948 to 1954. He also taught at the Indian Institute of Management Calcutta. His 1960 book ''The Human Side of Enterprise'' had a profound influence on education practices. McGregor was a student of Abraham Maslow. He has contributed much to the development of the management and motivational theory, and is best known for his Theory X and Theory Y as presented in his book ‘The Human Side of Enterprise’ (1960), which proposed that manager's individual assumptions about human nature and behavior determined how individual manages their employees.Jeong Chun Hai @Ibrahim, & Nor Fadzlina Nawi.

Frank Harary
Frank Harary (March 11, 1921 – January 4, 2005) was an American mathematician, who specialized in graph theory. He was widely recognized as one of the "fathers" of modern graph theory. Harary was a master of clear exposition and, together with his many doctoral students, he standardized the terminology of graphs. He broadened the reach of this field to include physics, psychology, sociology, and even anthropology. Gifted with a keen sense of humor, Harary challenged and entertained audiences at all levels of mathematical sophistication. A particular trick he employed was to turn theorems into games—for instance, students would try to add red edges to a graph on six vertices in order to create a red triangle, while another group of students tried to add edges to create a blue triangle (and each edge of the graph had to be either blue or red). Because of the theorem on friends and strangers, one team or the other would have to win. Biography Frank Harary was born in New Yo ...

Mennonite
Mennonites are groups of Anabaptist Christian church communities of denominations. The name is derived from the founder of the movement, Menno Simons (1496–1561) of Friesland. Through his writings about Reformed Christianity during the Radical Reformation, Simons articulated and formalized the teachings of earlier Swiss founders, with the early teachings of the Mennonites founded on the belief in both the mission and ministry of Jesus, which the original Anabaptist followers held with great conviction, despite persecution by various Roman Catholic and Mainline Protestant states. Formal Mennonite beliefs were codified in the Dordrecht Confession of Faith in 1632, which affirmed "the baptism of believers only, the washing of the feet as a symbol of servanthood, church discipline, the shunning of the excommunicated, the non-swearing of oaths, marriage within the same church, strict pacifistic physical nonresistance, anti-Catholicism and in general, more emphasis on "true Chris ...

Harwood Research
Harwood research refers to research in organizational psychology that took place at Harwood Manufacturing, a Virginia-based textiles manufacturer, over the course of four decades in the early to mid-Twentieth Century. History Harwood Manufacturing is a family textile company which became the site for a number of experiments in the behavioral sciences and workplace innovation, beginning in the late 1930s and extending over the next four decades. Shortly after Harwood Manufacturing had moved its operations from New England to Virginia the newly opened factory started to experience difficulties with recruiting skilled workers. As a result of the moving the company had to train 300 inexperienced people from the Virginia mountains- to meet the high production standards of the industrialized areas of the North America. Despite the fact that inexperienced trainees (who were mainly woman) were eager to work, on the job their pace was slow, their output was too low and the turnover was ...

Springfield College
Springfield College is a private college in Springfield, Massachusetts. It confers undergraduate and graduate degrees. It is known as the birthplace of basketball because the sport was invented there in 1891 by Canadian-American instructor James Naismith. The college's philosophy of "humanics... calls for the education of the whole person—in spirit, mind, and body—for leadership in service to others." History Founded in 1885, as the Young Men's Christian Association department of the School for Christian Workers in Springfield, the school originally specialized in preparing young men to become General Secretaries of YMCA organizations in a two-year program. In 1887, it added a Physical (''i.e.'', physical education) department. In 1890, it separated from the School for Christian Workers and became the YMCA Training School and in 1891, the International Young Men's Christian Association Training School. In 1905, the school became a degree-granting institution.Glenn T. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
