A New Scalable and Cost-Effective Congestion Management Strategy for Lossless Multistage Interconnection Networks
2005
In this paper, we propose a new congestion management strategy for lossless multistage interconnection networks that scales as network size and/or link bandwidth increase. Instead of eliminating congestion, our strategy avoids performance degradation beyond the saturation point by eliminating the HOL blocking produced by congestion trees. This is achieved in a scalable manner by using separate queues for congested flows. These are dynamically allocated only when congestion arises, and deallocated when congestion subsides. Performance evaluation results show that our strategy responds to congestion immediately and completely eliminates the performance degradation produced by HOL blocking whi…
Congestion Avoidance Using DYnamic COdec MAnagement: A solution for ISP
2005
The large diffusion of VoIP is an essential key for the success of emerging Internet service providers. These ISPs conflict with the interests of historical and predominant network maintainers which often control the network infrastructure and telephone services. To win this competition, emerging ISPs have to adopt strategic QoS solutions which will capture the attention of network users and phone clients. This paper presents a solution which is able to obtain the same performance of a 64 Kbps channel reducing the costs for over-provisioning network bandwidth. DyCoMa is a mechanism studied for VoIP applications in network with a limited bandwidth for multimedia services. It works preventing…
Perspectives et bilan après 20 ans de recherche et de stratégie au bas de la pyramide, une étude bibliométrique pour le futur du management internati…
2020
Conférence en ligne; International audience; Cet article propose une analyse bibliométrique du champ des stratégies au bas de la pyramide (BoP). Différents outils sont mobilisés pour analyser et comprendre la structure du champ et, plus généralement, en identifier les différentes écoles de pensée. 364 articles citant issus de la plateforme Web of Science fournissent une base de 15 292 références. Six groupes structurant le champ émergent de nos analyses, chacun mettant en évidence une spécificité des stratégies BoP. Le mapping de ce réseau de recherches permet d'envisager de nombreuses pistes de recherche et confirme l'intérêt du BoP comme axe de recherche futur du management international.

Some effects of color incongruity in a visual Ad
2009
32; While the effects of an ad's colour on attitudes towards it have already been investigated, far less work has been done on the influence of incongruous colours. This paper examines the effects of an ad using an incongruous colour on several variables of the advertising persuasion process. Analyses of variance have been conducted for an experimental study involving 407 respondents. The results show that a colour that is incongruous with the ad or with the product advertised affects the elements of surprise, perceived provocation, attitudes towards the ad and the positive beliefs about it.
Tappeti erbosi per la valorizzazione ambientale, ricreativa e sportiva del territorio urbano
2009
Nella società moderna, gli aggregati urbani sempre più estesi, den-samente abitati e separati dal mondo naturale e rurale circostante, ri-chiedono particolare attenzione per tutti gli elementi che possono mi-gliorarne la vivibilità. In tale contesto, il tappeto erboso trova una posizione strategica nella pianificazione urbana non solo per le sue funzioni ornamentali e architettoniche, ma soprattutto per il suo fondamentale contributo eco-logico, per la salute dell’uomo, il rispetto dell’ambiente e per una mi-gliore qualità della vita. In ambito urbano, diversi sono i benefits apportati dal tappeto erbo-so: mitigare gli effetti di degrado e gli impatti prodotti dalla presenza delle edificazi…
RISQUE ASSOCIE A L'UTILISATION DE LA LOI DE BENFORD POUR DETECTER DES VENTES FRAUDULEUSES DE BIENS INNOVANTS A LA MODE
2010
Benford's law has been promoted as providing the auditors with a turnkey solution for fraud detection. The purpose of this paper is to show it is not always possible to detect fraudulent sales with that law. We use sales in volume of game consoles in Japan (since 1989), in United-States, in France, in Germany and in United-Kingdom (since 2000). After reviewing briefly the literature and our study design, the chi-square test and the bias analysis were used to measure the goodness-of-fit to Benford's law. Despite the absence of actual fraud, these sale series of fashion goods are not significantly in conformity with Benford's law. Thus, for the detection of fraudulent sales in this sector, th…

Best practice strategies in business process redesign: an experimental study
2012
This paper presents investigates the determinants for best practices’ adoption in business process redesign. Specifically, we evaluate the role of the best practices in business process redesign by exploring their adoption dependences from the process typology and the goals of the redesign project. In order to answer to our research questions, we conducted an experimental study over 18 business process redesign projects carried out by 18 teams of students. The experimental study shows that there exists a business practice strategic orientation in redesigning a process, i.e. evident correlations exist among the adoption of specific practices with the adoption of other specific practices, but…
