Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Cathode ray tubes having reduced glass browning properties, U.S. Patent 6,097,144
No full textThe present invention provides an inexpensive cathode ray tube envelope which suffers considerably diminished glass browning in comparison with traditional cathode ray tube envelopes. The method of reducing glass browning in cathode ray tubes, and a suitable glass composite and glass composition are also provided. The cathode ray tube envelope of the present invention includes a screen which has an inner and an outer glass layers. The inner layer is made of lead-free glass whereas the outer layer is made of lead-containing glass. In the operational cathode ray tube of the present invention, the electron beams emitted therein, are absorbed by the inner layer without substantial browning, since the inner layer does not contain material that cause browning, and do not penetrate to the lead-containing outer layer. At the same time, the X-rays produced in the cathode ray tube are effectively and efficiently blocked by the lead-containing outer layer. The result is both significant reduction in glass browning and effective X-ray protection
Ellis Island today: Located in the Upper Bay west of Jersey City and southwest of Manhattan
No full textEllis Island is a significant historical site just up the bay from tiny Liberty Island in Upper New York Bay. Why? Because it was here that millions of immigrants first put foot in America. But where is Ellis Island? Until recently, a coastal boundary dispute between New York and New Jersey made the answer to that question uncertain. The island was originally only 3 or so acres but because of the filling of tidal waters around the island to create room to house and process the immigrants, the island grew to over 27 acres. New Jersey claimed jurisdiction to all those areas filled but New York insisted the entire island, no matter what its size, was hers based on a compact signed by the two states in 1834. In 1980 the State of New Jersey Department of Environmental Protection (NJDEP), as part of the statewide effort to delineate tidelands delineated a claim line that essentially claimed the entire filled portion of Ellis Island, except the original three acres. (In New Jersey, all lands flowed by the tide now or formerly are owned by the state). New York objected. The states continued to squabble. Finally, in 1993, the State of New Jersey invoked the Supreme Courts jurisdiction to try the dispute. Coastal boundaries have historically been mapped on linen, and more recently mylar, but in this case the NJDEP invoked the modern technology of GIS to assist the state?s attorney general in preparing the case. Historic maps were scanned and registered to modern ortho-photography to assist in determining where and when areas were filled. GPS points were gathered and surveys made. All the digital data was then analyzed on the GIS to show where and how much fill was placed in the area. New Jersey used these data to argue that those areas filled after the compact were indeed still under the jurisdiction of New Jersey (Ellis Island is a National Park and therefore ownership was not the issue). A special master determined, and on May 26th 1998 the Supreme Court agreed, that New Jersey had sovereign authority over the filled land added to the original island. New York retained authority to the original 3-acre island. GIS was then used to implement the Supreme Court?s decision. NJDEP GIS scientists delineated the line between states using historical digital maps and adjusted the boundary line between states to the satisfaction of all parties. This paper will detail this historic decision and the implementation of the decision and the critical role GIS played.This is an updated version of the presentation entitled: GIS and Coastal Boundary Disputes: Where is Ellis Island? In this updated version, the author has added slides in order to better explain how the angles in the Fort Gibson wall, that was constructed just prior to the War of 1812, were used to align the 1857 survey of Ellis Island with current island.There is a companion paper to the 1999 version of this presentation. See: Professional Surveyor, July August 1999, Vol. 19, Number 6, pp 8-14.Purpose: Describes the delineation of the jurisdictional boundary between New Jersey and New York, on Ellis Island, as per the Supreme Court ruling of 1998.

Looking Inside the Black Box of "Attendance at Services": New Measures for Exploring an Old Dimension in Religion and Health Research
No full textResearch in religion and health has spurred new interest in measuring religiousness. Measurement efforts have focused on subjective facets of religiousness such as spirituality and beliefs, and less attention has been paid to congregate aspects, beyond the single item measuring attendance at services. We evaluate some new measures for religious experiences occurring during congregational worship services. Respondents (N=576) were religiously-diverse community dwelling adults interviewed prior to cardiac surgery. Exploratory factor analysis of the new items with a pool of standard items yielded a readily interpretable solution, involving seven correlated but distinct factors and one index variable, with high levels of internal consistency. We describe religious affiliation and demographic differences in these measures. Attendance at religious services provides multifaceted physical, emotional, social, and spiritual experiences that may promote physical health through multiple pathways.This research was supported by grants from the National Institute on Aging (AG15160 and AG16750, Richard Contrada, PI).Published 2009 in International Journal for the Psychology of Religion at http://www.informaworld.com/smpp/content~db=all~content=a907482564~frm=titlelin

Syndrome l Ellis Van Creveld (manifestations oro-faciales d une ciliopathie)
No full textLe syndrome l Ellis Van Creveld est une dysplasie chondroectodermique, maladie rare, appartenant au groupe des ciliopathies. Sa prévalence est de 7 naissances sur 1 000 000. Elle se transmet selon un mode autosomique récessif et est donc plus fréquente en cas de consanguinité, avec un risque de récurrence de 25%. Ce nouveau groupe de maladies rares, les ciliopathies, est liée à l absence ou au dysfonctionnement d un organite cellulaire, le cil primaire, avec une incidence sur le développement squelettique et ectodermique. Le but de ce travail est de compiler la littérature disponible afin de déterminer à quel âge il est nécessaire d intervenir chez ces patients en fonction des signes présentés et quelle est la meilleure prise en charge à leur proposer. Les patients atteints par le syndrome l Ellis Van Creveld présentent des signes cliniques bien caractéristiques tels que : la polydactylie post-axiale, un nanisme dysharmonieux, des anomalies cardiaques des ongles et des dents. L analyse des signes cliniques généraux et des manifestations oro-faciales sera évoquée dans une première partie complétée par un tableau de synthèse des manifestations oro-faciales des cas cliniques étudiés. Dans une deuxième partie seront présentés les différentes techniques de diagnostic de ce syndrome en période anté et post-natal, ainsi que les autres syndromes appartenant au groupe des syndromes côtés courtes-polydactylie avec lesquels le diagnostic différentiel doit être fait. Dans une troisième partie, on cherchera à comprendre quels sont, au niveau du cil primaire, les mécanismes moléculaires qui engendrent ce syndrome et tous les aspects cliniques caractéristiques par l intermédiaire de la voie de signalisation Sonic Hedgehog. Enfin, l analyse des cas cliniques de la littérature permettra de donner quelques pistes de prise en charge de ces patients, en fonction de leur âge lors de leur arrivée au cabinet dentaire et des soins à réaliser.BORDEAUX2-BU Sci.Homme/Odontol.
