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 (...) performance, while specific and overall CSR scores are negatively associated with CEO-chair structures. Second, board gender diversity is positively associated with human rights and corporate governance dimensions. Third, age diversity is positively associated with corporate governance, human resources, human rights, and environmental activities. Also, our results provide evidence that outside directors care about CSR performance. Specifically, the presence of foreign directors is positively associated with environmental performance and community involvement, whereas CSR-Governance dimension is positively associated with the presence of independent directors. Regarding the director’s educational level, post-graduated directors are positively and significantly associated with overall CSR score and all CSR sub-scores, except the corporate governance one. When directors have multiple directorships, they are more concerned about human resources, environmental performance, and business ethics. Finally, our findings are robust only in non-family firms. In fact, family boards are less diverse than non-family ones; specifically, they have a lower number of independent, foreign, and high-educated directors. (shrink)

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 (...) intentions. In addition, a viral medium context triggers ‘unintended consequences’ that lead consumers to undermine the level of tabooness of the viral advertising and subjective norms. To increase the external validity of the research, the results were replicated for two kinds of controversial taboo appeals; one related to sexuality, and the other to death. The results provide useful implications for theory and practice. Extending viral advertising research, a different angle on controversial viral advertising has been taken, shifting from an advertiser and brand focus, to a societal and social one. The work leads to a better understanding of the ethics of controversial viral advertising, and demonstrates its role in the trivialization of taboo behaviors and imagery. The results confirm the need for more regulation of online buzz communication and encourage regulatory bodies to extend policies of viral advertising regulation. (shrink)

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 (...) context, the study investigates how these ad parodies can result in a detrimental impact on consumers’ perceptual and behavioral evaluations of the sponsoring brand. By implementing a tightly controlled experiment comparing actual CrM campaigns and CrM parodies, the author shows that the detrimental effects of CrM parodies on brand attitude and word-of-mouth valence can be explained by greater skepticism toward the firm’s sincere and altruistic motivations. In addition, the author shows that a robust asymmetry emerges in which CrM ad parodies damage perceptual and behavioral evaluations of brands more than actual CrM campaigns improve them. The authors replicate the results for two kinds of critics and two types of brands. The results provide useful implications for theory and practice, documenting the backfire effect of poorly designed CrM, which may urge brands to move toward more self-regulation of CrM practices.

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 (...) memory space while keeping the tool’s efficiency in terms of intrusion detection rate and false generated alarms. First, the interactions between the two nodes of the graph were grouped into a single interaction. The notion of equivalence class was used to classify the paths in the graph and was compressed by using a genetic algorithm. Such an approach showed its efficiency compared to the approach proposed by Pierre Clairet, by which the detection rate obtained was 99.9%, and no false-positive with a compression rate of illicit behaviour signature database reached 99.44%. Having these results is one of the critical aspects of realizing successful host-based intrusion detection systems. (shrink)

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.

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 (...) numerical simulations. (shrink)
