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
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.

Cultivating Professional Identity: The Vital Role of Practical Teaching Experience for Future Educators
No full textThis article endeavors to investigate the impact of three years of teaching experience acquired during student teaching training on the professional identity of aspiring educators. The ensuing literature review expounds upon the concepts of identity and professional identity. To scrutinize this subject comprehensively, a quantitative study was conducted, the details of which are elucidated in the subsequent section devoted to research methodology. The findings of this study underscore the paramount significance of fostering a sense of belonging and mission as integral components that underpin the means of support, adaptability, and PI development, particularly pertinent to student teachers and, especially, those immersed in the practical experience phase, as discerned through their self-perceptions. The principal conclusions and insights drawn from the cumulative body of research evidence underscore that, despite the recent recognition accorded the pedagogical training processes and their multifaceted impact on various aspects of a student’s life as a future educator, the teaching profession still remains underappreciated. The finding that emerged during this study underscores the heightened significance of teaching practices as an essential element in the preparation of a prospective graduate who aspires to become a pioneering educator in shaping the future of generations to come. The investigation surveyed 216 students pursuing teaching degrees, analyzing their professional identity development throughout their academic journey. Results revealed a positive association between the students’ advancement in their training curriculum and the enhancement of their professional identity. Specifically, as students progressed further in their studies, there was a discernible growth in their identification with the teaching profession

Anisotropic Friction for Deformable Surfaces and Solids
No full textThis paper presents a method for simulating anisotropic friction for deforming surfaces and solids. Frictional contact is a complex phenomenon that fuels research in mechanical engineering, computational contact mechanics, composite material design and rigid body dynamics, to name just a few. Many real-world materials have anisotropic surface properties. As an example, most textiles exhibit direction-dependent frictional behavior, but despite its tremendous impact on visual appearance, only simple isotropic models have been considered for cloth and solid simulation so far. In this work, we propose a simple, application-oriented but physically sound model that extends existing methods to account for anisotropic friction. The sliding properties of surfaces are encoded in friction tensors, which allows us to model frictional resistance freely along arbitrary directions. We also consider heterogeneous and asymmetric surface roughness and demonstrate the increased simulation quality on a number of two- and three-dimensional examples. Our method is computationally efficient and can easily be integrated into existing systems.Eurographics/ ACM SIGGRAPH Symposium on Computer AnimationDeformation, Contact, and Fractur
