Community mining is applied in order to identify groups of users which share, e.g., common interests or expertise. This paper presents an approach for mining descriptive patterns in order to characterize communities in terms of their distinctive features: For an efficient discovery approach, we introduce optimistic estimates for obtaining an upper bound for the community quality. We present an ...

A new approach is suggested under the slogan “Keep it Descriptive Stupid” (KIDS) that encapsulates a trend in increasingly descriptive agentbased social simulation. The KIDS approach entails one starts with the simulation model that relates to the target phenomena in the most straightforward way possible, taking into account the widest possible range of evidence, including anecdotal accounts an...

Descriptive analysis of music corpora is important to musicologists who are interested in identifying the properties that characterize specific genres of music. In this study we present such an analysis of a large corpus of folk tunes, all labeled by their origin. Subgroup Discovery (SD) is a rule learning technique located at the intersection of predictive and descriptive induction. One of the...

The purpose of this paper is to outline some recent progress in descriptive inner model theory, a branch of set theory which studies descriptive set theoretic and inner model theoretic objects using tools from both areas. There are several interlaced problems that lie on the border of these two areas of set theory, but one that has been rather central for almost two decades is the conjecture kn...

BACKGROUND To analyze the incidence and clinical-microbiological characteristics of osteomyelitis (OM) in a tertiary Spanish hospital. METHODS All cases diagnosed with OM between January 2007 and December 2010 were retrospectively reviewed. The variables examined include epidemiological characteristics, risk factors, affected bone, radiographic changes, histology, microbiological culture resu...

Expectation-confirmation theory (ECT) posits that satisfaction is determined by interplay of prior expectations and perception of delivery. As such, there are many applications in research and practice that employ an ECT model. The descriptive power allows independent investigations manipulating either of the components and a format to examine just why clients are satisfied (or not) with a part...

Computational complexity began with the natural physical notions of time and space Given a property S an important issue is the computational complexity of checking whether or not an input satis es S For a long time the notion of complexity referred to the time or space used in the compu tation A mathematician might ask What is the complexity of expressing the property S It should not be surpri...

Given the recent and highly publicized scandals involving psychology researchers who cheated, the proliferation of articles on related topics is unsurprising. As an example, Simons et al. (2011) pointed out subtle ways in which researchers can increase their false positive rate above the nominal level of p < 0.05. From my perspective, a major limitation of the literature on cheating has been a ...
