In recent years, researchers have investigated a growing number of weighted networks where ties are differentiated according to their strength or capacity. Yet, most network measures do not take weights into consideration, and thus do not fully capture the richness of the information contained in the data. In this paper, we focus on a measure originally defined for unweighted networks: the glob...

Network motifs are overrepresented interconnection patterns found in real-world networks. What functional advantages may they offer for building complex systems? We show that most network motifs emerge from interconnections patterns that best exploit the intrinsic stability characteristics of individual nodes. This feature is observed at different scales in a network, from nodes to modules, sug...

Exploring further the properties of ITRM -recognizable reals started in [Ca], we provide a detailed analysis of recognizable reals and their distribution in Gödels constructible universe L. In particular, we show that new unrecognizables are generated at every index γ ≥ ω ω . We give a machine-independent characterization of recognizability by proving that a real r is recognizable iff it is Σ1-...

Phytoextraction may be applied at field scale when the removal of bioavailable metals is the specific target of the technology. Residual metals in soil can be considered substantially inert or to be evaluated by site specific risk analysis.

Employees increasingly use cloud services of third party providers to efficiently perform their job. Interestingly, the majority adopts the cloud without approval of the organization. IT resources like that are commonly referred to as shadow IT. Although widespread in practice, the present literature on shadow IT is scarce lacking a clear definition of the phenomenon and exclusively focusing on...

It is very difficult to get a realistic picture of organizational activity. Yet without such a picture it is well nigh impossible to design Information Technology (IT) systems to properly support the work of the healthcare professional. This article reports on a study undertaken in conjunction with Mancunian Community Health Trust to model certain Trust processes. A number of different professi...

When two groups of market actors differ in how to interpret a common label, each can make claims over the label. One categorical interpretation and the group that supports it risk disappearance if the rival interpretation gains ground. We argue that when members of the endangered category become partial defectors that span categories, their history presents challenges to the identity of nondefe...
