Valdis Krebs
Valdis Krebs is an American-Latvian researcher, author, and consultant in the field of social and organizational network analysis. He is the founder and chief scientist of OrgNet, LLC, and the creator of InFlow software, which in 2008 Wired Magazine called one of the most advanced tools for analyzing and visualizing networks. Popular Science has described Krebs as a "leading expert" and a "pioneer" of network analysis, while Military.com's DefenseTech blog has called him a leading authority in the field. Work highlights After the September 11 attacks, Krebs used public information and newspaper clippings to produce a partial map of the organization behind the attacks. The resulting paperUncloaking Terrorist Networks has been called a classic, and "likely the most cited public analysis of the 9/11 network." After publishing it, he was "invited to Washington to brief intelligence contractors." Since 2004 Krebs has periodically published infographics showing the political polariza ...

Social Network Analysis
Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of ''nodes'' (individual actors, people, or things within the network) and the ''ties'', ''edges'', or ''links'' (relationships or interactions) that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, memes spread, information circulation, friendship and acquaintance networks, business networks, knowledge networks, difficult working relationships, social networks, collaboration graphs, 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. These visualizations provide a means of qualitatively assessing networks by varying the visual representation of their nodes and edges to reflect attributes of in ...

Organizational Network Analysis
Organizational network analysis (ONA) is a method for studying communication and socio-technical networks within a formal organization. This technique creates statistical and graphical models of the people, tasks, groups, knowledge and resources of organizational systems. It is based on social network theory and more specifically, dynamic network analysis. Applications ONA can be used in a variety of ways by managers, consultants, and executives. Network visualizations There are several tools that allow managers to visually depict their employee networks. Most of the tools are built specifically for researchers and academics who study Network theory, but are relatively inexpensive to use, as long as the leaders are well-versed on how to capture the information, feed it into the tool in the correct formats, and understand how to "read" and translate the network graphs into business decisions. Innovation gauge Several recent studies and research has highlighted that 'Psycholo ...

Wired Magazine
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online magazine, online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including ''Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophon (publishing), colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ' ...

Network Visualization
Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics. A drawing of a graph or network diagram is a pictorial representation of the vertices and edges of a graph. This drawing should not be confused with the graph itself: very different layouts can correspond to the same graph., p. 6. In the abstract, all that matters is which pairs of vertices are connected by edges. In the concrete, however, the arrangement of these vertices and edges within a drawing affects its understandability, usability, fabrication cost, and aesthetics. The problem gets worse if the graph changes over time by adding and deleting edges (dynamic graph drawing) and the goal is to preserve the user's mental map. Graphical conventions Graphs are frequently drawn as node–lin ...

September 11 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Center’s S ...

Infographics
Infographics (a clipped compound of "information" and "graphics") are graphic visual representations of information, data, or knowledge intended to present information quickly and clearly.Doug Newsom and Jim Haynes (2004). ''Public Relations Writing: Form and Style''. p.236. They can improve cognition by utilizing graphics to enhance the human visual system's ability to see patterns and trends.Card, S. (2009). Information visualization. In A. Sears & J. A. Jacko (Eds.), Human-Computer Interaction: Design Issues, Solutions, and Applications (pp. 510-543). Boca Raton, FL: CRC Press. Similar pursuits are information visualization, data visualization, statistical graphics, information design, or information architecture. Infographics have evolved in recent years to be for mass communication, and thus are designed with fewer assumptions about the readers' knowledge base than other types of visualizations. Isotypes are an early example of infographics conveying information quickl ...

Social Networks
A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics. Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Georg Simmel authored early structural theories in sociology emphasizing the dynamics of triads and "web of group affiliations". Jacob Moreno is credited with developing the first sociograms in the 1930s to study interpersonal relationships. These approaches were mathematically formalize ...

Bernie Madoff
Bernard Lawrence Madoff ( ; April 29, 1938April 14, 2021) was an American fraudster and financier who was the admitted mastermind of the largest Ponzi scheme in history, worth about $64.8 billion. He was at one time chairman of the NASDAQ stock exchange. He advanced the proliferation of electronic trading platforms and the concept of payment for order flow, which has been described as a "legal kickback." Madoff founded a penny stock brokerage in 1960, which eventually grew into Bernard L. Madoff Investment Securities. He served as the company's chairman until his arrest on December 11, 2008. That year, the firm was the 6th-largest market maker in S&P 500 stocks. At the firm, he employed his brother Peter Madoff as senior managing director and chief compliance officer, Peter's daughter Shana Madoff as the firm's rules and compliance officer and attorney, and his now deceased sons Mark Madoff and Andrew Madoff. Peter was sentenced to 10 years in prison in 2012, and Mark h ...

Ponzi Scheme
A Ponzi scheme (, ) is a form of fraud that lures investors and pays profits to earlier investors with funds from more recent investors. Named after Italian businessman Charles Ponzi, the scheme leads victims to believe that profits are coming from legitimate business activity (e.g., product sales or successful investments), and they remain unaware that other investors are the source of funds. A Ponzi scheme can maintain the illusion of a sustainable business as long as new investors contribute new funds, and as long as most of the investors do not demand full repayment and still believe in the non-existent assets they are purported to own. Some of the first recorded incidents to meet the modern definition of the Ponzi scheme were carried out from 1869 to 1872 by Adele Spitzeder in Germany and by Sarah Howe in the United States in the 1880s through the "Ladies' Deposit". Howe offered a solely female clientele an 8% monthly interest rate and then stole the money that the women ...
