Social Networks Fundamental problems in science and engineering have become increasingly interdisciplinary, requiring knowledge and expert input from several areas of research. This is both challenging and exciting. The primary challenge faced by researchers is to keep abreast of new developments in tangential research areas to their own, not to mention those which are considered different. The increasing complexity of newly arising problems has on the other hand, invariably required a multifaceted approach to viewing and understanding them, and ultimately produce a solution.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ The net-map toolbox is a social network analysis tool that uses interviews and mapping to help people understand, visualize, discuss, and improve situations in which many different actors influence outcomes. Social network analysis is a research approach used by scholars such as S.D. Berkowitz, Stephen Borgatti, Ronald Burt, Linton Freeman, Mark Granovetter, Nicholas Mullins, Anatol Rapoport, Stanley Wasserman, Barry Wellman, and Harrison White to better understand the implications of the position of individual actors in a social structure. Individuals create influence network maps using materials from a physical toolkit. Actor names are written on post-it notes and distributed on a large sheet of paper. Lines are drawn to link the actors and reveal how they are connected or not connected, and “influence towers” are built to reflect the relative power of each actor (the higher the influence tower, the greater the influence). Photos displaying these influence network maps are available on the Net-Map blog. Net-map was created in 2006 by Eva Schiffer, then a post-doctoral fellow at the International Food Policy Research Institute in Washington, DC. Dr. Schiffer developed the toolbox while working on a project in Ghana with the Challenge Program on Water and Food, a system-wide program of the Consultative Group on International Agricultural Research. Net-Map expands on the Power Mapping Tool (http://www.ifpri.org/publication/tracing-power-and-influence-networks). The White Volta River Basin Board in rural Ghana, responsible for overseeing local water resources, was looking to enhance decision making among its many collaborators. The Board used Net-Map to identify its partners, its linkages with those partners, and their distinct goals and levels of influence. A representation of the Board’s network map is available in a World Bank Sourcebook for Development Practitioners. Net-Map was also presented at the International Network of Social Network Analysis' International Sunbelt Social Network Conference in 2007. Several researchers have made the case for visual network mapping, specifically in improving development projects., a monitoring and evaluation specialist based in the United Kingdom, supports the use of a network perspective in representing and evaluating aid interventions. Boru Douthwaite, a Technology Policy Analyst at the International Center for Tropical Agriculture (CIAT) has used Participatory Impact Pathways Analysis (PIPA), which draws on many of the same concepts as Net-Map, to evaluate and manage development projects by directly engaging the participants. PIPA has been implemented through several workshops across the developing world, and is being developed by Mr. Douthwaite and other researchers from CIAT, as well as the WorldFish Center and the International Potato Center. The New Tactics in Human Rights Project—led by a diverse group of human rights international organizations, advisors and practitioners—uses visual network representations as one of its various innovative tools to promote human rights and end human rights abuses. Azmiri Mian, Centre for Human Resource Management, University of South Australia Business School, is using Net-Map Toolbox within the Human Resource Management and Organizational Behavior disciplines. Her PhD research is a mixed method case study to illustrate, interpret and explain employee social networks within an Indigenous organization. Ms Mian adapted the Net-Map Toolbox to develop individual Ego maps. This includes who the actors (participants) and alters (connections) are, what kind of a relationship it is, what factors contribute to the development of the network structure and who influences outcomes within the organization. Findings from this PhD study will become available on the Net-Map blog....

Social network
 
29:47
A social network is a social structure made up of a set of social actors (such as individuals or organizations) and a set of the dyadic ties between these 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 formalized in the 1950s and theories and methods of social networks became pervasive in the social and behavioral sciences by the 1980s. Social network analysis is now one of the major paradigms in contemporary sociology, and is also employed in a number of other social and formal sciences. Together with other complex networks, it forms part of the nascent field of network science. This video is targeted to blind users.

"Potentially destructive devices" sent to Clinton, Obama, CNN prompt massive response
 
04:29:26
A sprawling investigation unfolded Wednesday as authorities scrambled to respond to a series of suspicious packages. Two packages were addressed to the homes of two former presidents and another was addressed to former CIA Director John Brennan at the New York City offices of CNN, prompting CNN's bureau and the Time Warner Center to evacuate. The Secret Service said Wednesday morning it had intercepted the packages addressed to former President Obama's home in Washington and Bill and Hillary Clinton's residence in Westchester County, New York. Another package was originally addressed to former Attorney General Eric Holder, but was sent to the wrong address and returned to the office of former DNC chair Debbie Wasserman Schultz.

Clustering coefficient
 
08:49
In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together. Evidence suggests that in most real-world networks, and in particular social networks, nodes tend to create tightly knit groups characterised by a relatively high density of ties; this likelihood tends to be greater than the average probability of a tie randomly established between two nodes. Two versions of this measure exist: the global and the local. The global version was designed to give an overall indication of the clustering in the network, whereas the local gives an indication of the embeddedness of single nodes.
