Social Learning Network
A social learning network (SLN) is a type of social network that results from interaction between learners, teachers, and modules of learning.Brinton, Christopher G., and Mung Chiang.Social learning networks: A brief survey" Information Sciences and Systems (CISS), 2014 48th Annual Conference on. IEEE, 2014. The modules and actors who form the SLN are defined by the specific social learning process taking place. The set of learners and the set of teachers in an SLN cannot be disjoint. Rather, an SLN is an evolving peer learning process in which learners acquire, master, and then themselves disseminate knowledge to others over time. At any given time, an actor in an SLN is a teacher of concepts she has mastered, and a learner of those she is not yet familiar with. Collaborative learning has been identified as an important part of SLN formation, because actors can work together and combine their respective skills to solve problems. Applications A number of learning scenarios that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Network
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 for ...

Bipartite Graph
In the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets U and V, that is every edge connects a vertex in U to one in V. Vertex sets U and V are usually called the ''parts'' of the graph. Equivalently, a bipartite graph is a graph that does not contain any odd-length cycles. The two sets U and V may be thought of as a coloring of the graph with two colors: if one colors all nodes in U blue, and all nodes in V red, each edge has endpoints of differing colors, as is required in the graph coloring problem.. In contrast, such a coloring is impossible in the case of a non-bipartite graph, such as a triangle: after one node is colored blue and another red, the third vertex of the triangle is connected to vertices of both colors, preventing it from being assigned either color. One often writes G=(U,V,E) to denote a bipartite graph whose partition has the parts U and V, with E denotin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Content Analysis
Content analysis is the study of documents and communication artifacts, which might be texts of various formats, pictures, audio or video. Social scientists use content analysis to examine patterns in communication in a replicable and systematic manner. One of the key advantages of using content analysis to analyse social phenomena is its non-invasive nature, in contrast to simulating social experiences or collecting survey answers. Practices and philosophies of content analysis vary between academic disciplines. They all involve systematic reading or observation of texts or artifacts which are assigned labels (sometimes called codes) to indicate the presence of interesting, meaningful pieces of content. By systematically labeling the content of a set of texts, researchers can analyse patterns of content quantitatively using statistical methods, or use qualitative methods to analyse meanings of content within texts. Computers are increasingly used in content analysis to autom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multigraph
In mathematics, and more specifically in graph theory, a multigraph is a graph which is permitted to have multiple edges (also called ''parallel edges''), that is, edges that have the same end nodes. Thus two vertices may be connected by more than one edge. There are two distinct notions of multiple edges: * ''Edges without own identity'': The identity of an edge is defined solely by the two nodes it connects. In this case, the term "multiple edges" means that the same edge can occur several times between these two nodes. * ''Edges with own identity'': Edges are primitive entities just like nodes. When multiple edges connect two nodes, these are different edges. A multigraph is different from a hypergraph, which is a graph in which an edge can connect any number of nodes, not just two. For some authors, the terms ''pseudograph'' and ''multigraph'' are synonymous. For others, a pseudograph is a multigraph that is permitted to have loops. Undirected multigraph (edges with ...

Dynamic Problem (algorithms)
Dynamic problems in computational complexity theory are problems stated in terms of the changing input data. In the most general form a problem in this category is usually stated as follows: * Given a class of input objects, find efficient algorithms and data structures to answer a certain query about a set of input objects each time the input data is modified, i.e., objects are inserted or deleted. Problems of this class have the following measures of complexity: * Space the amount of memory space required to store the data structure; * Initialization time time required for the initial construction of the data structure; * Insertion time time required for the update of the data structure when one more input element is added; * Deletion time time required for the update of the data structure when an input element is deleted; * Query time time required to answer a query; * Other operations specific to the problem in question The overall set of computations for a dynamic problem i ...

Information Graphics
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 quickly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Review Site
A review site is a website on which reviews can be posted about people, businesses, products, or services. These sites may use Web 2.0 techniques to gather reviews from site users or may employ professional writers to author reviews on the topic of concern for the site. Early examples of review sites included ConsumerDemocracy.com, Complaints.com, planetfeedback.com, and Epinions.com. Business models Review sites are generally supported by advertising. Some business review sites may also allow businesses to pay for enhanced listings, which do not affect the reviews and ratings. Product review sites may be supported by providing affiliate links to the websites that sell the reviewed items, which pay the site on a per-click or per-sale basis. With the growing popularity of affiliate programs on the Internet, a new sort of review site has emerged: the affiliate product review site. This type of site is usually professionally designed and written to maximize conversions, and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterprise Social Networking
Enterprise social networking focuses on the use of online social networks or social relations among people who share business interests and/or activities. Enterprise social networking is often a facility of enterprise social software (regarded as a primary component of Enterprise 2.0), which is essentially social software used in "enterprise" (business/commercial) contexts. It encompasses modifications to corporate intranets (referred to as social intranets) and other classic software platforms used by large companies to organize their communication, collaboration and other aspects of their intranets. Enterprise social networking is also generally thought to include the use of a standard external social networking service to generate visibility for an enterprise. History Social networking sites started to form in the 1990s; an example of these websites is Theglobe.com, which began in 1995. As other websites such as GeoCities and Tripod.com started to form online communities, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Learning Theory
Social learning is a theory of learning process social behavior which proposes that new behaviors can be acquired by observing and imitating others. It states that learning is a cognitive process that takes place in a social context and can occur purely through observation or direct instruction, even in the absence of motor reproduction or direct reinforcement. In addition to the observation of behavior, learning also occurs through the observation of rewards and punishments, a process known as vicarious reinforcement. When a particular behavior is rewarded regularly, it will most likely persist; conversely, if a particular behavior is constantly punished, it will most likely desist. The theory expands on traditional behavioral theories, in which behavior is governed solely by reinforcements, by placing emphasis on the important roles of various internal processes in the learning individual. History and theoretical background In the 1941s, B. F. Skinner delivered a series of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Training And Development
Training and development involve improving the effectiveness of organizations and the individuals and teams within them. Training may be viewed as related to immediate changes in organizational effectiveness via organized instruction, while development is related to the progress of longer-term organizational and employee goals. While training and development technically have differing definitions, the two are oftentimes used interchangeably and/or together. Training and development have historically been topics within adult education and applied psychology but have within the last two decades become closely associated with human resources management, talent management, human resources development, instructional design, human factors, and knowledge management. History Aspects of training and development have been linked to ancient civilizations around the globe. Early training-related articles appeared in journals marketed to enslavers in the antebellum south and training approa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flipped Classroom
A flipped classroom is an instructional strategy and a type of blended learning, which aims to increase student engagement and learning by having pupils complete readings at home and work on live problem-solving during class time. This pedagogical style moves activities, including those that may have traditionally been considered homework, into the classroom. With a flipped classroom, students watch online lectures, collaborate in online discussions, or carry out research at home, while actively engaging concepts in the classroom, with a mentor's guidance. In traditional classroom instruction, the teacher is typically the leader of a lesson, the focus of attention, and the primary disseminator of information during the class period. The teacher responds to questions while students refer directly to the teacher for guidance and feedback. Many traditional instructional models rely on lecture-style presentations of individual lessons, limiting student engagement to activities in wh ...
