Stakeholder perspectives on organizational identity : searching for a relationship approach

Illia, Laura ; Lurati, Francesco

The present paper discusses the substantial difference for practice of current models of the relational nature of organizational identity which consider directly and indirectly the lookingglass process of organizational identity. The paper pinpoints that some models represent first useful step for an analysis of external interpretations of the organizations and that others represent an in-depth...

Understanding and managing knowledge-intensive conversations : an appreciative reading of the literature on conversations in organizations and an integrative approach for their management

Mengis, Jeanne ; Eppler, Martin J.

This article argues for the central role of conversations in knowledge-transformation processes in organizations. Given the importance attributed to conversations in the literature, but also the many conversational routines that often prevent knowledge creation and sharing, an integrative approach for managing knowledge-intensive conversations is needed. The article reviews the academic...

Homogenisation of a Canadian surface pressure database

Graham, Edward ; Slonosky, Victoria

This paper describes the collection, checking and homogenisation of a Canadian atmospheric surface pressure database. The object of the exercise was to create a database of monthly mean surface pressure for as many stations as possible across Canada as far back in time as possible. Data sources included the World Weather Records, Monthly Climatic Data for the World Bulletins, the Global...

Evidences of winter ascending air circulation throughout talus slopes and rock glaciers situated in the lower belt of alpine discontinuous permafrost (Swiss Alps)

Delaloye, Reynald ; Lambiel, Christophe

In: Norwegian Journal of Geography

The winter ascending circulation of air throughout an accumulation of coarse slope sediments (the so-called chimney effect) facilitates the cooling of the ground and even the occurrence of permafrost in the lower part of a deposit. Simultaneously, any freezing is unlikely to occur in the upper part. The chimney effect has been reported to date mainly for cold and sometimes perennially frozen...

Navier-Stokes systems with quasimonotone viscosity tensor.

Dreyfuss, Pierre ; Hungerbühler, Norbert

In: International Journal of Differential Equations and Applications

We (Dreyfuss P., Hungerbühler, N., 2004, Int. J. of Pure and Appl.Math. 14(2): 241– 271) investigated a class of Navier-Stokes systems which is motivated by models for electrorheological fluids. We obtained an existence result for a weak solution under mild monotonicity assumptions for the viscosity tensor. In this article, we continue the analysis of such systems, but with various notions...

Paradoxes in the logistic equation?

Gabriel, Jean-Pierre ; Saucy, Francis ; Bersier, Louis-Félix

In: Ecological Modelling

Levins and Ginzburg raised two paradoxes concerning the logistic equation of population growth. None of them received a satisfactory answer within the frame of the original equation. Here, we propose solutions to both paradoxes.
