Jean F. Coppola
No full textDr. Jean F. Coppola has always been a trailblazer in her various endeavors. Before pursuing an academic career as a technology professor and obtaining her doctorate, she worked at Pace University\u27s Division of Information Technology (now the Information Technology Services) as one of its technology specialists heavily involved with computers and networks. It was not unusual for her in those early days to be found crawling under tables, working with network cables, installing hardware, or tracing electrical outlets along walls and ceilings and even underneath floors. When computer technology was primarily predominated by men, Dr. Coppola was not only an active member of computer staff but was also heading her own unit.
Nowadays, as a professor in the Seidenberg School of Computer Science and Information Services, she is very much involved in the budding field of gerontechnology. She has been a much familiar face in local television and oft quoted by news services on features dealing with this discipline devoted to the developement of technology skills among senior citizens and the older adults.
A description about her in the eCommunique of the Seidenberg School of CSIS says Dr. Coppola has become a recognized leader in the emerging field of gerontechnology research, defined as the study of technology to promote the cognitive health of older adults and has won numerous awards, received significant press coverage, and granted modest research monies for her work. In mid-March, she, along with representatives from the other organizations that comprise the Consortium for Multi-faceted Gerontechnology Research located in Westchester County, will receive the 2009 Mind Alert Award for General Mental Fitness. Specifically, the award recognizes the research program in intergenerational computing that was conceived and implemented by Dr. Coppola. Begun in 2005, the program was designed to bridge the digital divide between older adults by enabling them to access and use computer technology.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Technological background of viscoelastic damping for space applications
No full textOne of the most important themes of the structural analysis is the vibration reduction. At present there are different devices which can be used to improve structural damping based on the use of active or passive dampers. Many studies on reduction and/or suppression of vibrations in LFSS and SFSS (Large/Small Flexible Space Structure) have been carried out in last decades. In this work a special smart structure will be proposed for the vibration suppression of composite panels. In particular the viscoelastic properties of a composite panel-structure will be changed opportunely in order to modify the elastic damping characteristics of the material which constitutes the panel. It is well known that these viscoelastic materials are characterized by the complex modulus. These moduli depend on two main parameters, the temperature T that material operates in and more interesting on the magnitude of the oscillating frequency ω the composite structure can be subjected at under a dynamic environment. In this study the determination of the complex modulus and the effect of above mentioned parameters on a composite panel for space applications are investigated. The sandwich panel here is made up of two carbon fibre skins and a polymeric core in analyzed. This core is constituted by an epoxy adhesive containing some silver conducting stripes opportunely distributed inside it. By applying a voltage to the ends of the silver stripes it is possible to produce a current which in turn generates heating, the epoxy resin and carbon skins, by Joule effect. The temperature acts on chemical bonds by increasing the molecular mobility and producing relaxation of the material which in turns varies the mechanical and thermal characteristics of the core and the resin matrix reducing the storage modulus, increasing the loss modulus and the loss factor. It's worth to note that this loss factor is directly related to the damping ratio of the panel. The viscoelastic parameters of the adhesive and of the carbon fibre will be experimentally estimated and evaluated using DMTA (Dynamic Mechanical and Thermal Analysis) Mathematical models and finite element simulations of this Heated Damping Sandwich Panel (HDSP) will be presented in order to study the coupling related to the thermal and structural interaction between the core, the skins and the silver electrical conductors. The stripe's cross section, the geometrical in-plane disposition and the electrical feeding will be found in order to have the minimum transitory time or the minimum necessary power for vibration suppression
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
