    Board Diversity and Corporate Social Responsibility: Empirical Evidence from France.Rania Beji, Ouidad Yousfi, Nadia Loukil & Abdelwahed Omri - 2021 - Journal of Business Ethics 173 (1):133-155.
    This study analyzes how the board’s characteristics could be associated with globally corporate social responsibility CSR and specific areas of CSR. It is drawn on all listed firms, in 2016, on the SBF120 between 2003 and 2016. Our results provide strong evidence that diversity in boards and diversity of boards globally are positively associated with corporate social performance. However, they influence differently specific dimensions of CSR performance. First, we show that large boards are positively associated with all areas of CSR (...)

    Does Viral Communication Context Increase the Harmfulness of Controversial Taboo Advertising?Ouidade Sabri - 2017 - Journal of Business Ethics 141 (2):235-247.
    Controversial taboo appeals as an executional cue in viral advertising have commonly been used by advertisers. In this context, the study investigates the role of medium context on the effectiveness of controversial taboo ads. By implementing a tightly controlled experiment which deals with controversial taboo ads embedded in a press article and in a viral context, the study finds that the viral medium context does not lead to a more positive attitude toward the embedded brand or to more positive purchase (...)

    The Detrimental Effect of Cause-Related Marketing Parodies.Ouidade Sabri - 2018 - Journal of Business Ethics 151 (2):517-537.
    Cause-related marketing, defined as a firm’s communication activities designed to promote a consumer good or service by including an offer to contribute a specified amount to a designated nonprofit cause, has become a preponderant practice. In tandem with the development of CrM activities, criticism of CrM has increased; critics note that some CrM claims mislead consumers regarding their purchases’ donative impact. Critics such as consumers and nonprofit advocates are using ad parodies, noncommercial messages that mimic an actual advertisement. In this (...)

    Improving the efficiency of intrusion detection in information systems.Bouderah Brahim, Nacer Eddine Yousfi, Bourenane Malika & Lounis Ouarda - 2022 - Journal of Intelligent Systems 31 (1):835-854.
    Policy Interaction Graph Analysis is a Host-based Intrusion Detection tool that uses Linux MAC Mandatory access control policy to build the licit information flow graph and uses a detection policy defined by the administrator to extract illicit behaviour from the graph. The main limitation of this tool is the generation of a huge signature base of illicit behaviours; hence, this leads to the use of huge memory space to store it. Our primary goal in this article is to reduce this (...)

  5. A Stochastic Switched Epidemic Model with Two Epidemic Diseases.Amine El Koufi, Abdelkrim Bennar & Noura Yousfi - 2021 - Complexity 2021:1-13.
    In this paper, we study a stochastic epidemic model with double epidemics which includes white noise and telegraph noise modeled by Markovian switching. Sufficient conditions for the extinction and persistence of the diseases are established. In the end, some numerical simulations are presented to demonstrate our analytical results.

    Dynamics of a Class of HIV Infection Models with Cure of Infected Cells in Eclipse Stage.Mehdi Maziane, El Mehdi Lotfi, Khalid Hattaf & Noura Yousfi - 2015 - Acta Biotheoretica 63 (4):363-380.
    In this paper, we propose two HIV infection models with specific nonlinear incidence rate by including a class of infected cells in the eclipse phase. The first model is described by ordinary differential equations and generalizes a set of previously existing models and their results. The second model extends our ODE model by taking into account the diffusion of virus. Furthermore, the global stability of both models is investigated by constructing suitable Lyapunov functionals. Finally, we check our theoretical results with (...)
