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
Discovery of a strongly lensed massive quiescent galaxy at z = 2.636: spatially resolved spectroscopy and indications of rotation
No full textWe report the discovery of RG1M0150, a massive, recently quenched galaxy at z = 2.636 that is multiply imaged by the cluster MACSJ0150.3-1005. We derive a stellar mass of log M* = 11.49 +0.10/-0.16 and a half-light radius of Re,maj = 1.8 ± 0.4 kpc. Taking advantage of the lensing magnification, we are able to spatially resolve a remarkably massive yet compact quiescent galaxy at z > 2 in ground-based near-infrared spectroscopic observations using Magellan/FIRE and Keck/MOSFIRE. We find no gradient in the strength of the Balmer absorption lines over 0.6Re - 1.6Re which are consistent with an age of 760 Myr. Gas emission in [N ii] broadly traces the spatial distribution of the stars and is coupled with weak Hα emission (log [N ii]/Hα = 0.6 ± 0.2), indicating that OB stars are not the primary ionizing source. The velocity dispersion within the effective radius is σe, stars = 271 ± 41 km s-1. We detect rotation in the stellar absorption lines for the first time beyond z ~ 1. Using a two-integral Jeans model that accounts for observational effects, we measure a dynamical mass of log Mdyn = 11.24 ± 0.14 and V/σ = 0.70 ± 0.21. This is a high degree of rotation considering the modest observed ellipticity of 0.12 ± 0.08, but it is consistent with predictions from dissipational merger simulations that produce compact remnants. The mass of RG1M0150 implies that it is likely to become a slowly rotating elliptical. If it is typical, this suggests that the progenitors of massive ellipticals retain significant net angular momentum after quenching which later declines, perhaps through accretion of satellites
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
Velocity Dispersions and Dynamical Masses for a Large Sample of Quiescent Galaxies at z > 1: Improved Measures of the Growth in Mass and Size
No full textWe present Keck LRIS spectroscopy for a sample of 103 massive (M > 10^(10.6) M☉) galaxies with redshifts 0.9 < z < 1.6. Of these, 56 are quiescent with high signal-to-noise absorption line spectra, enabling us to determine robust stellar velocity dispersions for the largest sample yet available beyond a redshift of 1. Together with effective radii measured from deep Hubble Space Telescope images, we calculate dynamical masses and address key questions relating to the puzzling size growth claimed by many observers for quiescent galaxies over the redshift interval 0 < z < 2. Our large sample provides the first opportunity to carefully examine the relationship between stellar and dynamical masses at high redshift. We find this relation closely follows that determined locally. We also confirm the utility of the locally established empirical calibration which enables high-redshift velocity dispersions to be estimated photometrically, and we determine its accuracy to be 35%. To address recent suggestions that progenitor bias—the continued arrival of recently quenched larger galaxies—can largely explain the size evolution of quiescent galaxies, we examine the growth at fixed velocity dispersion assuming this quantity is largely unaffected by the merger history. Using the velocity dispersion-age relation observed in the local universe, we demonstrate that significant size and mass growth have clearly occurred in individual systems. Parameterizing the relation between mass and size growth over 0 < z < 1.6 as R ∝ M^α, we find α = 1.6 ± 0.3, in agreement with theoretical expectations from simulations of minor mergers. Relaxing the assumption that the velocity dispersion is unchanging, we examine growth assuming a constant ranking in galaxy velocity dispersion. This approach is applicable only to the large-dispersion tail of the distribution, but yields a consistent growth rate of α = 1.4 ± 0.2. Both methods confirm that progenitor bias alone is insufficient to explain our new observations and that quiescent galaxies have grown in both size and stellar mass over 0 < z < 1.6
Interpretation of Richard III
No full textThis thesis aims to interpretation of William Shakespear?s play Richard III. The word ?interpretation? is used to describe generally valid analysis of the play, not an individual reading of the text.
The aim of the thesis is to search for the limits of this text and on the other side to detect the variability of the drama. Author is interested especially in those parts of the play, which could be explicated in more different ways.
The chapters are focused on conditions in the world of Richard III, on the position of Richard in the society, and describe Richard?s attitude to this world as well.
Special attention is payed to Richard?s clashes with other characters, causes of Richard?s fall and circumstances beyond his control.
The last part describes the theatrical potential of this drama
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. See: New Jersey v. New York, 523 U.S. 767 (1998)
