The London Stock Exchange: Strategic Corporate Governance Restructuring After Demutualization

2014

International audience; This study uses the London Stock Exchange (LSE), forced to demutualize due to major changes in its business environment, notably due to increased competition and technological advances, as field experiment to study corporate governance restructuring to adapt to new market conditions. The LSE improved its financial situation after demutualization and is an example of successful corporate governance restructuring. The LSE significantly restructured the composition of its board of directors following demutualization. The number of exchange members on the LSE board decreased after demutualization while the number of independent directors increased, pointing to a more “mo…

Dynamics of copper and zinc sedimentation in a lagooning system receiving landfill leachate.

2013

9 pages; International audience; This study characterises the sediment dredged from a lagooning system composed of a settling pond and three lagoons that receive leachates from a municipal solid waste (MSW) landfill in France. Organic carbon, carbonate, iron oxyhydroxides, copper (Cu) and zinc (Zn) concentrations were measured in the sediment collected from upstream to downstream in the lagooning system. In order to complete our investigation of sedimentation mechanisms, leachates were sampled in both dry (spring) and wet (winter) seasonal conditions. Precipitation of calcite and amorphous Fe-oxyhydroxides and sedimentation of organic matter occurred in the settling pond. Since different di…

Changing European storm loss potentials under modified climate conditions according to ensemble simulations of the ECHAM5/MPI-OM1 GCM

2007

Abstract. A simple storm loss model is applied to an ensemble of ECHAM5/MPI-OM1 GCM simulations in order to estimate changes of insured loss potentials over Europe in the 21st century. Losses are computed based on the daily maximum wind speed for each grid point. The calibration of the loss model is performed using wind data from the ERA40-Reanalysis and German loss data. The obtained annual losses for the present climate conditions (20C, three realisations) reproduce the statistical features of the historical insurance loss data for Germany. The climate change experiments correspond to the SRES-Scenarios A1B and A2, and for each of them three realisations are considered. On average, insure…

Novel bibliographic maps to guide research units

2014

National audience; Publication is a major issue for research evaluation. As a consequence research units need strategies to improve their publications. Bibliometry and cartography are new tools to study the publications of research teams. In particular bibliometry give an overall picture and good criteria to choose a strategy for publishing and to guide the priorities of research. Here we studied the publications of the INRA Agroécologie research unit, Dijon. This unit has 107 scientists and professors, equivalent 80 full-time positions for research, and published 125 original articles in 2012. We present several examples of maps and measurements obtained using Web of science, Excel, Sphinx…

Strategic tillage in Conservation Agriculture : consequences on weed communities and winter wheat productivity

2021

In Europe, Conservation Agriculture is currently challenged by higher weed pressure, potential glyphosate ban andreduced crop yield. The introduction of strategic tillage could be a viable option to diversify selection pressures onweeds and increase crop yield. Three types of fallow management (ploughing (CT), reduced tillage (RT), no-till withglyphosate (NT)) were compared on four fields after 17 years of no-plough, which ended with 7 years of NT. Weeddensity, weed composition, crop productivity and yield components were assessed in the following winter wheat.The reintegration of tillage after 17 years of Conservation Agriculture proved to be a major driver of weed communities before weedi…

Measuring Distraction at the Levels of Tactical and Strategic Control: The Limits of Capacity-Based Measures for Revealing Unsafe Visual Sampling Mod…

2011

The control theory of driving suggests that driver distraction can be analyzed as a breakdown of control at three levels. Common approach for analyzing distraction experimentally is to utilize capacity-based measures to assess distraction at the level of operational control. Three driving simulation experiments with 61 participants were organized to evaluate which kind of measures could be used to analyze drivers' tactical visual sampling models and the related effects of distraction while searching textual information on in-car display. The effects of two different text types were evaluated. The utilized capacity-based measures seemed to be insufficient for revealing participants' tactical…

Larval zebrafish as an in vitro model for evaluating toxicological effects of mycotoxins.

2020

The presence of mycotoxins in food has created concern. Mycotoxin prevalence in our environment has changed in the last few years maybe due to climatic and other environmental changes. Evidence has emerged from in vitro and in vivo models: some mycotoxins have been found to be potentially carcinogenic, embryogenically harmful, teratogenic, and to generate nephrotoxicity. The risk assessment of exposures to mycotoxins at early life stages became mandatory. In this regard, the effects of toxic compounds on zebrafish have been widely studied, and more recently, mycotoxins have been tested with respect to their effects on developmental and teratogenic effects in this model system, which offers …

What have we learnt about board gender diversity as a business strategy? The appointment of board subcommittees

2018

This is the pre-peer reviewed version of the following article: What have we learnt about board gender diversity as a business strategy? The appointment of board subcommittees, which has been published in final form at https://doi.org/10.1002/bse.2226. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions. This paper explores whether a board's gender diversity influences the voluntary formation of its board subcommittees. Female board directorship may become a business strategy for firms if it affects the appointment of board subcommittees. We hypothesize that the voluntary creation of board subcommittees is affe…

Exploring the Role of Informants in Interpretive Case Study Research in IS

2011

Interpretive case study research constitutes an important and increasing part of the information systems (IS) knowledge base (Walsham, 1993; Myers, 1997; Pare and Elam, 1997; Walsham, 2006). Interpretive case studies can be distinguished from positivist case study research (Benbasat et al., 1987; Lee, 1989; Dube and Pare, 2003) by the focus on close interaction between researcher and participants throughout the case study process, viewing the case members as active participants in the construction of the case narrative (Boland, 1985; Guba and Lincoln, 1989; Kvale, 2002). However, while the interpretivist perspective ascribes an active role to the case study informants, in practice the exten…
