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
Lattice phenomenology of minimal walking technicolor
No full textAs results from the Large Hadron Collider (LHC) begin to shed light on the
physics of the electroweak scale, which has been of primary interest to theorists
for many years, we have entered a phase where critical judgement of the many
models of electroweak symmetry breaking (EWSB) that have been developed in
recent years will be possible.
As this process continues, those models which are not additionally constrained
by emerging data attract increased scrutiny and interest. In this respect,
technicolor models, in which EWSB occurs dynamically through the spontaneous
chiral symmetry breaking in a new strongly coupled sector, are the subject of
growing research activity.
The focus of this work is a program of investigation of Minimal Walking
Technicolor (MWT), a candidate theory for the new strongly coupled sector of a
model of dynamical EWSB using Lattice Gauge Theory (LGT) techniques.
We have performed an improved comprehensive study of mesonic spectral
observables within MWT, with emphasis on nite volume e ects arising from
nite temporal and spatial boundaries. Our results clarify the role of nite
volume e ects in such studies, while con rming the near-conformal behaviour
of the theory in the infra-red, and indicating a relatively small value of the mass
anomalous dimension, in agreement with other studies.
We also describe a calculation of the leading order hadronic vacuum polarisation
contribution to the anomalous magnetic moment of the muon from a lattice
simulation of 2+1
avour lattice QCD using Domain Wall Fermions (DWF).
We investigate in detail a number of systematic uncertainties involved in this
calculation, determining how to e ectively bring them under control, and obtain
a result in close agreement with previous determinations from LGT studies, from
calculations based on independent experimental data, and from experimental measurements.
We present a preliminary calculation of the contribution to the electroweak
S parameter from MWT, using a mixed-action simulation involving the DWF
action used for the valence sector combined with gauge con gurations generated
using the Wilson fermion action for sea quarks
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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Some continuum physics results from the lattice V-A correlator
No full textExtent: 7p.We present preliminary results on extractions of the chiral LECs L10 and C87 and constraints on the excited pseudoscalar state (1300) and (1800) decay constants obtained from an analysis of lattice data for the flavor ud light quark V-A correlator. A comparison of the results for the correlator to the corresponding mildly-model-dependent continuum results (based primarily on experimental hadronic decay data) is also given.P.A. Boyle, L.

Lattice determination of the hadronic contribution to the muon g-2 using dynamical domain wall fermions
No full textWe present a calculation of the leading-order hadronic contribution to the anomalous magnetic moment of the muon for a dynamical simulation of 2+1 flavor QCD using domain wall fermions. The electromagnetic 2-point function is evaluated on the lattice gauge configurations and this is fitted to a continuous form motivated by models of vector dominance. We find broad agreement with previous lattice results for this quantity, while improvements in simulation and theory are clearly needed in order to produce satisfactorily precise results.Peter Boyle, Luigi Del Debbio, Eoin Kerrane, and James Zanott

When the past comes back to haunt you: Exploring reverse consumer socialization processes through the life course perspective
No full textUsing a life course perspective, we explore how primary consumer socialization experiences inform reverse consumer socialization processes. We identify four types of reverse socialization behaviours (relinquishers, persistent proactives, autocratic dictators, and self-interested instructors) which played out as adult children taught their parents consumer skills, informed by relationship quality/who initiated learning
