The experience of uncertainty, typically attributed to a lack of knowledge, is central to the study of information behaviour. Uncertainty also arises, however, from real-world indeterminacy that no amount of information can resolve. This paper explores the multiple sources of psychological uncertainty and examines the implications for information behaviour research and practice.

Being innovative is a popular but ambiguous maxim in LIS. To elucidate how institutions use, and what they mean by the concept, we examine white literature and survey website features of 160 libraries across US and Canada. We identify patterns in the language and ethos of modern innovative librarianship.Être novateur est une maxime populaire bien qu’ambigüe en science de l’information. Pour mieux comprendre comment les institutions l’utilisent et quelle est la signification du concept, nous avons analysé les documents officiels et le contenu des sites Web de 160 bibliothèques aux États-Unis et au Canada. Sont identifiés des modèles d’utilisation langagière et l’ethos de la bibliothéconomie moderne novatrice. ***Full paper in the Canadian Journal of Information and Library Science***

Though innovation is a popular theme of LIS literature, its specific meaning for libraries remains obscure. Clarifying the implicit definition of innovation in librarianship can facilitate a more meaningful use of the term. To do so, we employ a ground-up exploration of innovation through the white literature in conjunction with a detailed survey of website features, of 160 libraries across the United States and Canada.

Abstract.Architectural patterns have an impact on both the structure and the behavior of a system at the architecture design level. However, it is challenging to model patterns' behavior in a systematic way because modeling languages do not provide the appropriate abstractions and because each pattern addresses a whole solution space comprised of potentially infinite solution variants. In this paper, we advocate the use of architectural primitives for systematically modeling architectural patterns in the behavioral view. These architectural primitives are found among a number of architectural patterns and serve as the basic building blocks for modeling patterns' behavior. The main contribution of this work lies in the discovery of architectural primitives, defining architectural primitives using UML, and capturing the missing pattern semantics by using UML's stereotypes.

Architectural patterns are often combined with other, relevant architectural patterns during software architecture design. However, combining patterns effectively remains a challenging task: first because the integration of any two architectural patterns can take several forms; second because existing pattern languages only mention generic pattern-to-pattern relationships and do not go into the details of their combination. In this paper, we propose to address this problem by discovering and defining a handful of recurring pattern relationships at the level of the participants of patterns. We have studied 32 industrial case studies and mined a number of relationships between participants of different patterns.We present a few of these relationships and outline some examples of their appearance.
