Model Checking Synchronized Products of Infinite Transition Systems

open access: yes, 2007
Formal verification using the model checking paradigm has to deal with two aspects: The system models are structured, often as products of components, and the specification logic has to be expressive enough to allow the formalization of reachability ...

“There Are Places Full of Beauty”: Desettling High School Students' Scientific Writing

open access: yesScience Education, EarlyView.
ABSTRACT This study contributes to desettling and expanding expectations about the forms of scientific language that belong in students' scientific writing. The primary empirical focus is the analysis of 52 high school student abstracts articulating community‐based investigations, submitted as part of their participation in a student conference in a ...

Approximation of proximities by aggregating T-indistinguishability operators [PDF]

open access: yes, 2007
For a continuous Archimedean t-norm T a method to approximate a proximity relation R (i.e. a reflexive and symmetric fuzzy relation) by a T-transitive one is provided.

A Bird's Eye View of English Grammar: Connecting the Dots in Two Dimensions

open access: yesTESOL Quarterly, EarlyView.
Abstract Over the past few decades, discussions on grammar instruction have primarily focused on teaching methodologies, such as whether grammar should be taught explicitly or implicitly, and whether the focus should be on form or forms. This paper, however, shifts the focus to grammar itself, aiming to provide a “shape” for pedagogical grammar.

Transitive closure and betweenness relations

open access: yesFuzzy Sets and Systems, 2001
Indistinguishability operators fuzzify the concept of equivalence relation and have been proved a useful tool in theoretical studies as well as in di0erent applications such as fuzzy control or approximate reasoning. One interesting problem is their construction. There are di0erent ways depending on how the data are given and on their future use.

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

open access: yesJournal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

Algorithmic and Hardness Results for the Colorful Components Problems

open access: yes, 2013
In this paper we investigate the colorful components framework, motivated by applications emerging from comparative genomics. The general goal is to remove a collection of edges from an undirected vertex-colored graph $G$ such that in the resulting graph

Towards an anthropology of acquisition: ‘How did you get that?’ Vers une anthropologie de l'acquisition : « Où as‐tu trouvé ça ? »

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The production‐distribution‐consumption triad has structured how anthropologists understand exchange for roughly a century. This article argues for expanding this triad to include an explicit focus on acquisition – the systems, processes, and practices of acquiring.

Practical Reasoning for Very Expressive Description Logics

open access: yes, 1999
Description Logics (DLs) are a family of knowledge representation formalisms mainly characterised by constructors to build complex concepts and roles from atomic ones.
