Exploring the Managerial Dynamics in a Turbulent Context: The Reaction of SMEs’ Leaders

Small and medium enterprises constitute the bulk of the Lebanese economic fabric. Over the past decades, the managers of these SMEs have played a pivotal role in the survival of their businesses. This research aims at understanding how these managers manage to survive in a turbulent context marked by perpetual changes that are almost constantly renewing themselves, by showing how, in such an environment, they manage to mobilize resources and skills and deploy dynamic capacities in order to develop efficient and sustainable practices. The results of qualitative research of the exploratory type are intended to present researchers with a "reaction model" that, in a similar context, could enlighten SME leaders on the managerial performance required

Understanding emergence in business model development: how companies interact with stakeholders to deal with environmental ambiguity

Cette recherche explore le caractère émergent du développement d’un business model en adoptant une perspective sensemaking. Une majeure partie des approches du business model adopte une vision rationnelle, considérant de manière prépondérante les choix délibérés au détriment de phénomènes émergents. Par conséquent, nous interrogeons ici les mécanismes d’émergence intervenant dans le processus de développement du business model.À partir d’une étude de cas longitudinale, nous examinons le développement d’un business model sur une période de 22 mois. Nous identifions des mécanismes de sensemaking émergents et délibérés qui forment trois ‘patterns’. Ces derniers peuvent être ‘enactés’ par les acteurs pour le développement du business model et l’affinement des tactiques

Theoretical study of Acousto-optical coherence tomography using random phase jumps on US and light

Acousto-Optical Coherence Tomography (AOCT) is variant of Acousto Optic Imaging (called also ultrasonic modulation imaging) that makes possible to get z resolution with acoustic and optic Continuous Wave (CW) beams. We describe here theoretically the AOCT e ect, and we show that the Acousto Optic tagged photons remains coherent if they are generated within a speci c z region of the sample. We quantify the z selectivity for both the tagged photon eld, and for the M. Lesa re et al. photorefractive signal
