The Quest for Citations: Drivers of Article Impact
No full textWhy do some articles become building blocks for future scholars, while many others remain unnoticed? We aim to answer this question by contrasting, synthesizing and simultaneously testing three scientometric perspectives – universalism, social constructivism and presentation – on the influence of article and author characteristics on article citations. To do so, we study all articles published in a sample of five major journals in marketing from 1990 to 2002 that are central to the discipline. We count the number of citations each of these articles has received and regress this count on an extensive set of characteristics of the article (i.e. article quality, article domain, title length, the use of attention grabbers and expositional clarity), and the author (i.e. author visibility and author personal promotion). We find that the number of citations an article in the marketing discipline receives, depends upon “what one says†(quality and domain), on “who says it†(author visibility and personal promotion) and not so much on “how one says it†(title length, the use of attention grabbers, and expositional clarity). Our insights contribute to the marketing literature and are relevant to scientific stakeholders, such as the management of scientific journals and individual academic scholars, as they strive to maximize citations. They are also relevant to marketing practitioners. They inform practitioners on characteristics of the academic journals in marketing and their relevance to decisions they face. On the other hand, they also raise challenges towards making our journals accessible and relevant to marketing practitioners: (1) authors visible to academics are not necessarily visible to practitioners; (2) the readability of an article may hurt academic credibility and impact, while it may be instrumental in influencing practitioners; (3) it remains questionable whether articles that academics assess to be of high quality are also managerially relevant.Impact;Citation Analysis;Referencing;Scientometrics;Cite
Médias sociaux et entreprise, une route pleine de défis Commentaires invités
No full textInternational audienceLes opportunités que les médias sociaux offrent aux consommateurs, aux entreprises et aux chercheurs en marketing sont quasiment infinies, comme le montrent, entre autres, les articles de ce numéro spécial. Cependant, nous ne devrions pas oublier que ces opportunités, tout aussi prometteuses qu'elles puissent sembler, ne surviennent pas toutes seules, mais apportent avec elles un ensemble unique de défis. Nous avons demandé à quatre éminents chercheurs spécialisés dans le domaine de la recherche sur les médias sociaux de faire des commentaires sur ces défis. Les médias sociaux impliquent-ils que chaque entreprise devra se considérer comme une maison d'édition dans le futur? Comment les nouveaux types de données fournis par les médias sociaux doivent-ils être analysés et cela requiert-il de nouvelles approches fondamentalement différentes? Et comment le « retour sur média social » peut-il être déterminé d'une façon fiable et analytique? Rejoignez-nous dans la lecture de ce que John Deighton, Peter Fader, Barak Libai et Eitan Muller ont à dire sur ces questions
Deniable Ring Signatures
No full textThesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.Includes bibliographical references (p. 55-57).Ring Signatures were developed by Rivest, Shamir and Tauman, in a paper titled How to Leak a Secret, as a cryptographically secure way to authenticate messages with respect to ad-hoc groups while still maintaining the signer's anonymity. While their initial scheme assumed the existence of random oracles, in 2005 a scheme was developed that does not use random oracles and meets the strongest security definitions known in the literature. We argue that this scheme is not deniable, meaning if someone signs a message with respect to a ring of possible signers, and at a later time the secret keys of all of the possible signers are confiscated (including the author), then the author's anonymity is no longer guaranteed. We propose a modification to the scheme that guarantees anonymity even in this situation, using a scheme that depends on ring signature users generating keys that do not distinguish them from other users who did not intend to participate in ring signature schemes, so that our scheme can truly be called a deniable ring signature scheme.by Eitan Reich.M.Eng
The second Lebanon war and the operation protective Edge / Tzuk Eitan as examples of asymmetric conflicts in the middle east
No full textIn the article there are analysed characteristics of an asymmetry of a contemporary battlefield on the grounds of the Second Lebanon War in 2006 and the Operation Protective Edge / Tzuk Eitan in the Gaza Strip in 2014. In the beginning the author presents Polish and Israeli definitions of an asymmetric conflict and its manifestations. Further, there are described causes of both conflicts and capabilities the parties had at their disposal before the direct military confrontation. Then, there are specified forms as well as measures undertaken by the Israel Defence Forces in the fight against Hezbollah in South Lebanon and Hamas in Gaza. The result is the characteristics of an asymmetry in the Middle East and the description of the evolution process of activity and structures of terrorist organisations and the Israel Defence Forces. This made it possible to show the process of learning and adjusting actions to the way the enemy operates, its potential and conditions surrounding both state and non-state actors

Discrete viscous sheets
No full text© Christopher Batty, Andres Uribe, Basile Audoly, Eitan Grinspun | ACM 2012. This is the author's version of the work. It is posted here for your personal use. Not for redistribution. The definitive Version of Record was published in ACM Transactions on Graphics, http://dx.doi.org/10.1145/2185520.2185609.We present the first reduced-dimensional technique to simulate the dynamics of thin sheets of viscous incompressible liquid in three dimensions. Beginning from a discrete Lagrangian model for elastic thin shells, we apply the Stokes-Rayleigh analogy to derive a simple yet consistent model for viscous forces. We incorporate nonlinear surface tension forces with a formulation based on minimizing discrete surface area, and preserve the quality of triangular mesh elements through local remeshing operations. Simultaneously, we track and evolve the thickness of each triangle to exactly conserve liquid volume. This approach enables the simulation of extremely thin sheets of viscous liquids, which are difficult to animate with existing volumetric approaches. We demonstrate our method with examples of several characteristic viscous sheet behaviors, including stretching, buckling, sagging, and wrinkling.This research is supported in part by the Sloan Foundation, the NSF (grants CMMI-11-29917, IIS-11-17257, IIS-10-48948, IIS- 09-16129, CCF-06-43268), and generous gifts from Adobe, Au- todesk, Intel, mental images, NVIDIA, Side Effects Software, and The Walt Disney Company.
