Statistical properties of community structure in large social and information networks
"... A large body of work has been devoted to identifying community structure in networks. A community is often though of as a set of nodes that has more connections between its members than to the remainder of the network. In this paper, we characterize as a function of size the statistical and structur ..."

domains. Our results suggest a significantly more refined picture of community structure in large realworld networks than has been appreciated previously. Our most striking finding is that in nearly every network dataset we examined, we observe tight but almost trivial communities at very small scales
From Practice Fields to Communities of Practice
"... In writing this chapter, we (a constructivist and a situativity theorist) struggled with the distinction between situativity and constructivism. and the implications in terms of the design of learning contexts. In clarifying (and justifying) our two sides, we created straw man and pOinted fingers wi ..."

from both the constructivist and situativity perspective that knowledge is situated through experience. In the context of this chapter, we found it trivial to distinguish among those learning theories and principles related to constructivism and those related to situativity theory. Rather, we discuss
Is ϕ 4 theory trivial?
, 806
"... The fourdimensional ϕ 4 theory is usually considered to be trivial in the continuum limit. In fact, two definitions of triviality were mixed in the literature. The first one, introduced by Wilson, is equivalent to positiveness of the GellMann – Low function β(g) for g = 0; it is confirmed by all ..."

The second definition, introduced by mathematical community, corresponds to the true triviality, i.e. principal impossibility to construct continuous theory with finite interaction at large distances: it needs not only positiveness of β
Is small talk in the workplace really “trivial”?
"... Small talk has generally been perceived as trivial and as not beneficial to workplaces in any way. However, it is observed that small talk does frequently occur in most workplaces among coworkers and even among subordinates and superiors. This gives rise to the suggestion that small talk is not tota ..."

Drawing on workplace scenes from the two movies ‘The devil wears Prada ’ and ‘Working Girl’, this paper examines the distribution of small talk, its functions among coworkers, and its benefits for managers. This paper also adopts a community of practice (CofP) approach in examining how a
Automatically parcellating the human cerebral cortex.

Abstract We present a technique for automatically assigning a neuroanatomical label to each location on a cortical surface model based on probabilistic information estimated from Introduction Techniques for labeling geometric features of the cerebral cortex are useful for analyzing a variety of fu ..."

While
ON THE REPRESENTATION THEORY OF FINITE JTRIVIAL MONOIDS
 SÉMINAIRE LOTHARINGIEN DE COMBINATOIRE
, 2011
"... In 1979, Norton showed that the representation theory of the 0Hecke algebra admits a rich combinatorial description. Her constructions rely heavily on some triangularity property of the product, but do not use explicitly that the 0Hecke algebra is a monoid algebra. The thesis of this paper is tha ..."

is that considering the general setting of monoids admitting such a triangularity, namely Jtrivial monoids, sheds further light on the topic. This is a step in an ongoing effort to use representation theory to automatically extract combinatorial structures from (monoid) algebras, often in the form of posets
NonTrivial Solutions to the NPerson Prisoners ’ Dilemma
"... We have developed a new agentbased simulation tool to model social dilemmas for the case of a large number of not necessarily rational decisionmakers (Szilagyi and Szilagyi, 2000). The combination of various personalities with stochastic learning makes it possible to simulate the multiperson Pris ..."

A variety of personality profiles and their arbitrary combinations can be represented, including agents whose probability of cooperation changes by an amount proportional to its reward from the environment. For the case of such agents the game has nontrivial
Clustering on the unit hypersphere using von misesfisher distributions
 Journal of Machine Learning Research
, 2005
"... Several large scale data mining applications, such as text categorization and gene expression analysis, involve highdimensional data that is also inherently directional in nature. Often such data is L2 normalized so that it lies on the surface of a unit hypersphere. Popular models such as (mixtures ..."

Numerical estimation of the concentration parameters is nontrivial in high dimensions since it involves functional inversion of ratios of Bessel functions
Tedious Work, Trivial Details? A Fresh Look at Bibliographic Citation

Applying concepts of rhetorical theory to source acknowledgment allows us to develop rational explanations for many of the differences between APA and MLA styles (see inset for examples). In fact, the research I’ll present in this workshop suggests that both of thes ..."

To combat this curse of success, many reviews have appeared in the last 2 years [e.g., (2)], and books on graphene are in the making. The electronic
