Theory and realism
If you are new to social network analysis, initial steps can be daunting. Its recommended that you begin from an introductory text. Some examples are Social Networks: An Introduction by Jeroen Bruggeman, Social Network Analysis: A Handbook by John Scott, and Exploratory Social Network Analysis with Pajek by Wouter de Nooy et al. The last book is the only text that initiate a beginner into a social network analysis software.
Problems of Structure, Dynamics and Causality
E.g., the problem with the new books of John Levi Martin, is that structure is assumed to simple gell out of repetition, and it is concrete interaction and local structure, not emergence of more global structure interacting with local structure, that leads to the appearance of structural dynamics, but no means of testing causality. Many of his assumptions are merely opinions and are not empirically justified. In contrast:
- Test of a Causal models realistic modeling of time-series dynamics: The Jajmani --> Market transition
Simplicity (e.g., Methodological individualism) and Complexity (e.g., Global and local structure)
Definition of multilevel network as system
Definition of complexity as a system of units as beginning with the ratio of internal delay time in unit response to interaction time between units.
The "complex structure of forager social networks" is a good candidate for causal network analysis. The authors note (2007:2195) "Complex systems composed of multiple interacting parts tend to self-organize or evolve structures that maximize whole-system performance by optimizing among the intersection of components."

Basic Concepts and Metrics
See for example Power law Zipfian generator
Social network analysis, aiming at precision, initiated a set of shared formal vocabulary. This is one of the main hurdles in comprehending its concepts. These were mostly extracted from Bruggeman so you are encourage to start from that book.
Actors -- Humans or organizations represented by nodes.
Adjacency matrix -- A matrix where rows and columns are mirror image of ties between pairs of actors. Only one type of relationships are shown in one matrix.
Affiliations -- Places or events where an actor can establish relationships. E.g. an event, a school, a workplace, and so forth.
Alters -- People related to an ego.
Arc -- A relationship with a directional property. E.g. 'A' loves 'B' but 'B' does not necessarily love 'A', direction from A to B. An oriented edge only goes in one direction (nonreciprocated arc)
Assortive mating -- See homophily.
Assortive mixing -- Behavior where nodes get attached to nodes with similar numbers of ties.
Attrition -- A behavior where information is lost as its passed down in a social network. May be compensated by within cohesive sets of nodes.
Bridge -- A sole relationship connecting two components.
Clique -- A component with at least 3 actors and all actors connect to each other (complete subgraph).
Cohesion -- Usually estimated by relative density (e.g., "community detection") but in a strict sense this is incorrect, see structural cohesion or connectivity-k which is a true measure of cohesion. NetWiki CommunityDetection browse: A nonparametric view of network models and Newman–Girvan and other ... large networks by Aaron Clauset, Mark Newman, and Cristopher Moore
Component -- A subset of a social network where every node is connected to every other either directly or through indirect paths. Also known as connected graph.
Connected graph -- See component.
Degree -- Number of relationships an actor has. See in- and -out-degree.
Density -- #Edges/MaxPossibleEdges in a component or graph. Density = x/maximum. For oriented graphs, maximum = n(n-1). For non-oriented graphs (symmetric arcs or 'edges' only), maximum = n(n-1)/2. The term 'graph' is typically used for non-oriented graph.
Diameter -- Longest geodesic in a graph.
Digraph -- A term for directed graph.
Directed Graph -- A social network which its relationships have directional properties. See Arc.
Disassortive mixing -- Behavior where nodes get attached to nodes with contrastive numbers of ties.
Dyads -- A pair; relationship where the direction goes both way. See arc and edges.
Edges -- Represented by lines without arrow head in social network diagram. Implies a two way relationship. See dyad.
Ego network -- A network of people surrounding a single ego, and their relationships. See alters. Alters are those in an ego's network, and the number of algers is ego's degree.
ERGM -- Exponential Random Graph Models, which estimate with (See:) motifs at a smaller scale within the graph that are randomly combined in different proportions to compose the entire graph. Robins (2009) MCMC for ergm reviews "exponential random graph models, a family of statistical models for modeling social networks. Full model specification requires formulation of a dependence hypothesis which proposes how possible network ties are conditionally dependent on each other. The dependence hypothesis in effect sets out the processes whereby network ties self organize into small micro-structures (network configurations). These can be construed as the building blocks of the global network structure. The paper presents three dependence assumptions that result in different types of graph distribution: (1) Bernoulli graph distributions whereby ties are assumed to be independent of each other; (2) Markov random graph distributions whereby ties are assumed to be conditionally dependent if they share a node; and (3) social circuit dependence where dependence emerges from observed ties, such that two possible ties become dependent if their observation would create a four cycle." See: Markov random graph as estimators.
Exponential distribution -- (negative exponential distribution), a continuous probability distribution that describes the times between events in a process in which events occur continuously and independently at a constant average rate (Poisson process). E.g., "a good approximate model for the time until the next phone call arrives" betweeb 2-4 pm" or "until a radioactive particle decays." Empirically, such a distribution tends to be linear is semi-log while a power law tends to be linear in log-log. See: [[Aaron Clauset] for a reference on the problem of curve-fitting for empirical univariate distributions.
Fractal network -- A network where actors are connected by repeated pattern throughout.
Geodesic -- Shortest path between two nodes. See Geodesic of the entire network.
Geodesic of the entire network -- Mean geodesic of all nodes in a graph.
Graph -- A social network diagram. Or, in graph theory a set of vertices V and pairs of vertices E in VxV called edges.
Homophily -- A behavior where actors tend to connect with people similar to themselves. E.g., assortive mating.
Hub -- A node with a unusually large number of relationships.
Incidence matrix -- A matrix with actors in its rows and affiliations in its columns. See affiliations.
Motifs -- Smaller subgraphs within a network whose frequencies can be censused and modeled by ERGM or other models.
Lattice -- a set of nodes that is a partially ordered set with a binary operator ^ (meet) or v ('join') where every pair of nodes has a unique supremum as the closure of the operation. Thus if a and b 'meet' in c but also in d then c and d must also 'meet', and so on, ad infinitum. If ^ is an immediate supervisor of two employees a and b for example, and they have two such supervisors, there must be some eventual supervisor of supervisors that is unique. This is supervisory condition that can be used to define an organizational hierarchy. A (regular) lattice may also consist of lines that intersect (regularly), e.g., a two-dimensional lattice of orthogonal lines intersecting on a planar surface, a three-dimensional lattice doing so in a 3-dimensional space, and so forth.
Lines -- Represent relationships in social network diagram.
Local clustering -- Calculation is the same as density, but only an ego's and its alters ties are considered. See density and local clustering of entire network.
Local clustering of entire network -- Mean of all local clustering values. See local clustering.
Luck -- Might be used as the name of a parameter for a node establishing a relationship with another node, e.g., 0 = no decays, 1 = maximum decay for a probability that decays with distance.
Markov random graphs -- defined by a particular dependence structure between network ties... see ERGM
Multigraph -- A social network that shows more than one type of relationships. Graphically, the lines are usually differentiated by colors.
Multilevel graph -- a network in which a node at one level may contain a network of relations at the next level. Use for a complex system, for kinship networks, e.g., links between families that contain individual members as defined by Bourbaki algebraist André Weil and used by White, Jorion, Houseman and others.
Nodes -- Represent actors in a social network. Represented by Dots in social network diagram. (See actors)
Normal distribution -- Gaussian distribution, e.g., of number of relationships a node may have. Chance of a node having a large number of relationships is negligible. May apply to relationships with high rate of decay.
Path length -- Number of ties between starting and ending nodes connected by a series of edges (directed or undirected).
Power law distribution -- An hypothesis about a univariate distribution that is linear in the log-log plot of an interval or ratio-level variable logged on the x axis (e.g., network degree of nodes) and log of frequencies on the y-axis. Clausett, Shalizi and Newman (2009) provide software for rigorous inferential statistical tests needed to establish this property of a univariate distribution as against other distributions of high variance (Zipfian and “power law”, Yule-Simon, etc., where the mean is not representative of most samples) and low-variance (Gaussian or Normal, exponential, Maxwell-Boltzmann, Raleigh, etc.). Zipf's is the special case where the product of rank by frequency is constant in a frequency distribution.
Power law generator -- A probability generating function p~k governed by a power constant or exponent (typically alpha~1). (Note that the alpha of the generating function and the log-log slope of the generated distribution will differ). If k is the degree (# links) of each node in a network and p governs a generating process for graphical evolution through adding edges (proportional to their degree), the network is called scale-free and the network generated will also have a degree distribution in which the frequency of nodes with degree k that follows a power law distribution p~k. The power gamma for the generated distribution function will be larger than the exponent alpha in the generating equation (typically 2 < gamma < 3, and no greater than 3 for alpha of 1=preferential attachment). With power law distributions it is much easier, compared to the tail of the normal distribution, to find a node with many relationships. Many things obey power law, e.g. waiting time at clinic, number of friends, etc.
Power law Zipfian generator -- The mathematics of Zipf - having the properties of successive occurrences of "a system with an unbounded number of possible states", "expected for a system evolving to a stable state between order and chaos." Bernat Corominas-Murtra and Ricard Solé 2010, "Universality of Zipf's law", Physical Review E, 82:011102 abstract. Zipf's is also analogous to the special case of a frequency power-law distribution where the product of frequency by quantity (or by rank in the Zipf) is constant.
Power law with cutoff -- A Power law for the lower part of the distribution (degree in a network: fewer ties) up to a cutoff where the distribution might become exponential, for example. This might reflect cases where relationships demand high maintenance, therefore each node can only have a certain number of ties. But the chance of find nodes of many relationships is still greater than normal because the lower part of the distribution is power law. Another type of power law cutoff occurs as a lower bound below which the distribution is no longer power law. All power laws must have a lower cutoff because no phenomena can become infinitely small (an all log scales go to infinitesimals).
Preferential attachment -- A network attachment process for nodes, proportional to past attachments, e.g. "rich get richer", "fame begets more fame", etc. Albert-László Barabási <Linked> falsely attributes a preferential attachment process to networks with a power-law degree distribution, but there are many other generative processes for this feature that he fails to consider.
Relation - a distribution on pairs of elements (e.g., nodes in a network) which may be of three types: reflexive (loops for a node with itself), symmetric (aRb entails bRa), or asymmetric (not necessarily symmetric). An entire relation R may be reflexive (all pairs reflexive, with loops), symmetric, antisymmetric (no symmetries) or asymmetric (aRb may or may not entail bRa, also called nonsymmetric), transitive (aRb and bRc entails aRc), antitransitive, or nontransitive (also called atransitive). A graph is typically defined as a symmetric irreflexive relation. A digraph is typically defined as an asymmetric irreflexive relation (edges are directed, i.e., arcs, which may or may not be reciprocated). An oriented graph is typically defined as an antisymmetric irreflexive relation. Many theorems in graph theorem are possible by excluding reflexivity, i.e., by defining edges and arcs as going away from the node rather than reflexive.
Searchability -- The ability for one node to find a target -- another node in the graph -- by means of some efficient (better than random) algorithm. For scale free networks this requires a beta parameter (see Power law) between 2 and 2.5 (Lada Adamic et al 2003) for a hub search to be efficient (better than random search). In Kleinberg's (regular) lattice model for networks (of dimension 2, 3 or higher) a luck or beta parameter (between randomness and order) governing generation with additional links with distance decay, e.g., p~d so that beta=0 is random, and beta=2 makes a two-dimensional lattice optimally searchable while beta=3 makes a three-dimensional lattice optimally searchable, and so forth (i.e., the beta distance decay must match the lattice dimension so as to strike a balance of neither moving too far or too near in finding the target.
Solidarity -- A state in a social network where mutual expectations have developed. Implies stable relationships over a period of time. Related to cohesion.
Tie -- A generic term for relationships. Encompasses both edges and arc.
Threshold -- A predetermined minimal amount of interactions for social contacts to be considered a relationship. A predictor for emotional intensity, for example.
Transitivity -- A relation xRy between nodes xy is transitive if aRb and bRc entails aRc. This may be measured for triples abc by the ratio T = 3xT_Triads / Connected triples. T = transivity. Triads = # of transitive triads in a graph. Connected triples = Number of triples in a graph that are connected (at least one path connecting abc).
Triples -- Connected Triples describes three nodes where there is a path between them but they they are not necessarily completely connected. In the general case a triple is any three nodes in a graph with whatever links they have between them.
Valued graph -- A social network where lines adopt a number showing its intensity. Graphically, the lines are usually differentiated by thickness.
Vertices -- See Nodes.
***Communication Networks- an interest of Yong Ming Kow, 2007 and other items
Julsrud, Tom E. 2007 Core/periphery Structures and Trust in Distributed Work Groups: A comparative case study. Structure and Dynamics: eJournal of Anthropological and Related Sciences 2(2)
Yong Ming: Communication networks in institutions were often ignored in the past, or developed around organizational control. But with availability of more ICTs (e.g. the Int'l Test Commission rules for the Internet), we are seeing growing importance of uncontrolled, informal networks, to acquire information critical to productivity (). This has two implications for ICTs design: (1) ICTs need to support communication with external parties that support an institution's work, e.g. consultants, suppliers; (2) Traditional institutional structure maybe out-dated .
Traditional institutional structure maybe defined as one with departmentalized multi-functional workgroups. Engineers may form one department, and marketing, sales, and designs follow the same. Such workgroups face numerous problems in recent decades resulting in new development since the 1980s in collaborative styles. Some of these are the cross-functional team and agile software development. These are seen as improvisation to support information hungry teams to temporary increase their information 'bandwidth.' However, these measures are only temporarily as team members ultimately return to their respective functions.
[What are the advantages of functional teams? Efficiency, effectiveness for routine tasks. How routine are tasks in knowledge organizations?]
Borrowing from the triadic structure of social networks, what are the advantages if professions in project teams are organized, purposefully as such? Instead of relying on 'sociable' individuals to break the ice and do the job of cross-functional/hierarchical communication, which is problematic, how about purposefully organizing an organization by triads of different professions into highly connect web? But how dense is optimum?
Prompts: To what extent can ethnography, sociology, history, ..., ..., benefit from the theoretical and representational frameworks of networks and complexity?
Can these frameworks provide realism - and how is realism related to abstraction v. modeling? Can we leave the positivist concept of modeling behind? See empirical formalism.
