Towards a Better Comprehension of Adaptation to Information and Communication Technologies: A Multi-level Approach

Despite the variety of literature on ‘adaptation to technology’, the literature still witnesses a gap concerning the concept of adaptation especially about its multi-level nature. Recognizing the multilevel nature of IS adaptation, we rise the challenge of conducting an alternate template analysis of three cases of adaptation to IS in order to provide complementary explanations about the phenomenon. In order to expand the comprehension of the ‘adaptation’ concept, a multi-study dissertation model is adopted. The objective is to examine the adaptation concept on three different levels: the individual, the group level, and the organizational level. This thesis aims at 1) exploring the shaping of individual adaptive actions that knowledge workers engage towards technostress with a focus on the factors that influence their adaptation process; 2) examining the adaptive performance of a group facing an newlyimplemented technology based on the adaptive structuration theory (DeSanctis and Poole 1994) under which were puzzled the concepts of affordances (Leonardi 2011, Leonardi, Huysman et al. 2013) and the structure of usage (Burton-Jones and Straub Jr 2006, Burton-Jones and Gallivan 2007); 3) examining, through an organizational learning lens (Argyris and Schon 1978), the case of an organizational adaptation to environmental technological changes examined within a managerial cognition conceptual framework (Orlikowski and Gash 1994); (Bijker 1987, Bijker 1995). To answer the different research questions, the three studies adopt a qualitative approach falling within a critical realist perspective

Investigation of the effect of consolidation on cement flow behaviour

International audienceOne of the main problems affecting the flow of cement bulk powder is the formation of cohesive arching at the outlet of the hopper, causing blockage of the silo opening and bridge formation. A simple concept is established which outlines these complications. In this context, the interactions of particles lead to a high degree of consolidation of the cement powder and an increase of adhesion force due to the small size and the large surface area of the cement particles. The results from the consolidation test and the flow properties (cohesion) show that the cement powder flow is mainly controlled by internal forces (Van der Waals and adhesion forces) and external forces. These forces have a direct influence on the powder structure, leading to a variable packing behaviour. Since the problem is attributable mainly to interparticle forces, before storage of the cement powder in the silo, the powder should be fluidised with air at a high velocity to disintegrate the cohesive structure and to overcome this undesirable property of cement flow
