Evolutionary algorithm for fiber laser in ultrashort pulse regime
2016
This thesis deals with the generation of ultrashort pulses within a fiber laser cavity through the automatic optimization of its parameters by an evolutionary algorithm. The interest of this subject comes from the difficulty to systematically explore dynamics in a large domain of experimental parameters. We have shown that it is possible to implement an evolutionary algorithm on fiber laser cavity with appropriate precautions. We have experimentally demonstrated for the first time the mode locking of a laser cavity only using the optimization of polarization controllers through an automatic and self-learning procedure. We also have demonstrated that selecting the mode locking from it radio-…
The chemical composition of the floral extract of Epipogium Aphyllum sw. (Orchidaceae): A cluefor thier pollination biology
2014
Epipogium aphyllum is a rare European obligate mycoheterotrophic orchid lacking chlorophyll. It has not been studied previously with respect to pollination biology. We studied the association between the composition of floral scent emission and its pollination systems. Field observation indicates that the main pollinators of Epipogium aphyllum are representatives of the genus Bombus (Hymenoptera), B. lucorum, B. hortorum, B. terrestris, B. pascuorum and B. proteus, and the genus Apis (Hymenoptera) namely A. mellifera. The main potential vector (observed to accidentally carry pollen), is most likely Episyrphus balteatus (Diptera, Syrphidae). The chemical composition of the floral extracts of…
Studying radical organizational innovation through grounded theory
2000
The main aim of this article is to study the social processes occurring during the implementation of radical organizational innovation. Our aim is to understand the nature of the development of radical innovation by identifying the social processes, that are taking place. The perspective for the analysis stems from grounded theory as a generative and inductive analytical strategy (Glaser & Strauss, 1967). An in-depth case study was thoroughly analysed. A total of 14 indepth interviews were conducted with key informants selected according to theoretical sampling criteria. The systematic use of the constant comparative method allowed us to differentiate grounded theories leading to a c…
The Role of External Environment in Upper Echelons Theory
2014
Upper echelons research has largely focused on the antecedents and consequences of top management teams (TMTs) from the team and firm levels of analysis. This paper reviews empirical research on TMTs with a specific emphasis on the role of the external environment. Applying institutional and industrial organization theories, a cross-level conceptual model outlining the direct, mediating, and moderating effects of the external environment on upper echelons is developed. This review distinguishes between industry and institutional levels of analysis and three types of environmental characteristics: stable, dynamic, and transformational. The paper further explains the relationships between ea…
Managing mergers – governancing institutional integration
2016
- Despite striking similarities, the adoption and implementation of policy shifts regarding higher education governance vary considerably across the globe, suggesting a mixed picture of diversification and isomorphism both within and across national higher education systems. By unpacking one particular structural reform process, this paper focuses on mergers as both a governance tool and a governance result in higher education. The paper analyzes the strategic decisions taken by Norwegian higher education institutions during 2014 in the light of a proposed national reform to merge institutions in order to enhance quality in higher education. The empirical basis of the paper consists of anal…
The skill paradox: explaining and reducing employment discrimination against skilled immigrants
2015
Using a social identity theory approach, we theorized that recruiters might be particularly biased against skilled immigrant applicants. We refer to this phenomenon as a skill paradox, according to which immigrants are more likely to be targets of employment discrimination the more skilled they are. Furthermore, building on the common ingroup identity model, we proposed that this paradox can be resolved through human resource management (HRM) strategies that promote inclusive hiring practices (e.g., by emphasizing fit with a diverse clientele). The results from a laboratory experiment were consistent with our predictions: Local recruiters preferred skilled local applicants over skilled immi…
Le tweet stratégique: Use of Twitter as a PR tool by French politicians
2015
Edited By Dejan Verčič, Ana Tkalac Verčič, Krishnamurthy Sriramesh and Jon White; National audience; This study, adopting a qualitative approach to political communication, looks in depth at the way Twitter is used as a PR tool by five French politicians. It suggests that the microblogging service plays a specific role in allowing them to monitor public opinion and current affairs, to interact with voters, journalists, stakeholders and other politicians and to disseminate information. The way politicians use Twitter is influenced by concerns of impression management (content and style of tweets), and also various institutional, political and social/symbolic limits, which contribute to revea…
Corporate social irresponsibility: review and conceptual boundaries
2017
PurposeThe purpose of this paper is to carry out a review of the academic literature about corporate social irresponsibility (CSIR) highlighting aspects that help us to define socially irresponsible behaviour and its relationship with socially responsible behaviour.Design/methodology/approachThrough a Boolean search of studies related to terms of irresponsibility undertaken from 1956 to October 2016, the authors develop a review of the literature focussing on the main perspectives used for defining the term of CSIR.FindingsThe paper provides a framework of three main dimensions for understanding the differences in the literature that defines CSIR: who defines irresponsible behaviour, an imp…
Organizing for What: Job Rotation as an Organizational Development Strategy or as an Organizational anti-Corruption Tool?
2021
The purpose of this article is to understand if Job Rotation (JR)/Organizational Development (OD)-oriented strategies are compatible with JR strategies to curb Organizational Corruption (OC), as these strategies seem to indicate an apparent contradiction. To this end, the paper is structured as follows. Firstly, the main points of JR-Theory in organizational studies are displayed. Subsequently, JR-Theory in organizational anti-corruption is more deeply explored. At the end of the review, the research question is proposed in the methodological section. The two sections after that are devoted to answering this question. The first of which examines the laws and documents of the National Anti-C…
Ecosystem services mapping and assessment for policy- and decision-making : Lessons learned from a comparative analysis of European case studies
2020
This paper analyses and compares a set of case studies on ecosystem services (ES) mapping and assessment with the purpose of formulating lessons learned and recommendations. Fourteen case studies were selected during the EU Horizon 2020 “Coordination and Support Action” ESMERALDA to represent different policy- and decision-making processes throughout the European Union, across a wide range of themes, biomes and scales. The analysis is based on a framework that addresses the key steps of an ES mapping and assessment process, namely policy questions, stakeholder identification and involvement, application of mapping and assessment methods, dissemination and communication and implementation.
