Citation Analysis: A Comparison of Google Scholar, Scopus, and Web of Science
When faculty members are evaluated, they are judged in part by the impact and quality of their scholarly publications. While all academic institutions look to publication counts and venues as well as the subjective opinions of peers, many hiring, tenure, and promotion committees also rely on citation analysis to obtain a more objective assessment of an author’s work. Consequently, faculty members try to identify as many citations to their published works as possible to provide a comprehensive assessment of their publication impact on the scholarly and professional communities. The Institute for Scientific Information’s (ISI) citation databases, which are widely used as a starting point if not the only source for locating citations, have several limitations that may leave gaps in the coverage of citations to an author’s work. This paper presents a case study comparing citations found in Scopus and Google Scholar with those found in Web of Science (the portal used to search the three ISI citation databases) for items published by two Library and Information Science full-time faculty members. In addition, the paper presents a brief overview of a prototype system called CiteSearch, which analyzes combined data from multiple citation databases to produce citation-based quality evaluation measures
Two Alternative Yet Complementary Conceptual Frameworks for Financing American Education
Outlines strategies to integrate systemic performance-based reform, which assumes that improving the school system will help all students meet standards, and out-of-school interventions, which attempts to mitigate the effects of poverty and other factors
A taxonomy for emergency service station location problem
The emergency service station (ESS) location problem has been widely
studied in the literature since 1970s. There has been a growing interest in the subject especially after 1990s. Various models with different objective functions and constraints have been proposed in the academic literature and efficient solution techniques have been developed to provide good solutions in reasonable times. However, there is not any study that systematically classifies different problem types and methodologies to address them. This paper presents a taxonomic framework for the ESS location problem using an operations research perspective. In this framework, we basically
consider the type of the emergency, the objective function, constraints, model
assumptions, modeling, and solution techniques. We also analyze a variety of papers related to the literature in order to demonstrate the effectiveness of the taxonomy and to get insights for possible research directions
RFID Localisation For Internet Of Things Smart Homes: A Survey
The Internet of Things (IoT) enables numerous business opportunities in
fields as diverse as e-health, smart cities, smart homes, among many others.
The IoT incorporates multiple long-range, short-range, and personal area
wireless networks and technologies into the designs of IoT applications.
Localisation in indoor positioning systems plays an important role in the IoT.
Location Based IoT applications range from tracking objects and people in
real-time, assets management, agriculture, assisted monitoring technologies for
healthcare, and smart homes, to name a few. Radio Frequency based systems for
indoor positioning such as Radio Frequency Identification (RFID) is a key
enabler technology for the IoT due to its costeffective, high readability
rates, automatic identification and, importantly, its energy efficiency
characteristic. This paper reviews the state-of-the-art RFID technologies in
IoT Smart Homes applications. It presents several comparable studies of RFID
based projects in smart homes and discusses the applications, techniques,
algorithms, and challenges of adopting RFID technologies in IoT smart home
systems.Comment: 18 pages, 2 figures, 3 table
The use and effectiveness of the eLib subject gateways: a preliminary investigation
Internet subject gateways were set up under the Electronic Libraries Programme (eLib) in order to address some of the problems of searching the Internet which have been identified by information professionals, i.e. locating relevant, good quality information. This preliminary study examines the extent to which academics in two universities use three eLib subject gateways (EEVL, OMNI and SOSIG). The results are generally encouraging for the eLib programme, but it is necessary for the gateways to be more effectively promoted. The study also found that academics do not have the same misgivings about the general search engines as the information professionals and seem to use them more readily than the gateways
DETERMINING LOCATIONS FOR RURAL MEDICAL CLINICS: A MODEL AND ITS USE
Community/Rural/Urban Development,
London SynEx Demonstrator Site: Impact Assessment Report
The key ingredients of the SynEx-UCL software components are:
1. A comprehensive and federated electronic healthcare record that can be used to
reference or to store all of the necessary healthcare information acquired from a
diverse range of clinical databases and patient-held devices.
2. A directory service component to provide a core persons demographic database to
search for and authenticate staff users of the system and to anchor patient
identification and connection to their federated healthcare record.
3. A clinical record schema management tool (Object Dictionary Client) that enables
clinicians or engineers to define and export the data sets mapping to individual
feeder systems.
4. An expansible set of clinical management algorithms that provide prompts to the
patient or clinician to assist in the management of patient care.
CHIME has built up over a decade of experience within Europe on the requirements
and information models that are needed to underpin comprehensive multiprofessional
electronic healthcare records. The resulting architecture models have
influenced new European standards in this area, and CHIME has designed and built
prototype EHCR components based on these models. The demonstrator systems
described here utilise a directory service and object-oriented engineering approach,
and support the secure, mobile and distributed access to federated healthcare
records via web-based services.
The design and implementation of these software components has been founded on
a thorough analysis of the clinical, technical and ethico-legal requirements for
comprehensive EHCR systems, published through previous project deliverables and
in future planned papers.
The clinical demonstrator site described in this report has provided the solid basis
from which to establish "proof of concept" verification of the design approach, and a
valuable opportunity to install, test and evaluate the results of the component
engineering undertaken during the EC funded project. Inevitably, a number of
practical implementation and deployment obstacles have been overcome through
this journey, each of those having contributed to the time taken to deliver the
components but also to the richness of the end products.
UCL is fortunate that the Whittington Hospital, and the department of cardiovascular
medicine in particular, is committed to a long-term vision built around this work. That
vision, outlined within this report, is shared by the Camden and Islington Health
Authority and by many other purchaser and provider organisations in the area, and
by a number of industrial parties. They are collectively determined to support the
Demonstrator Site as an ongoing project well beyond the life of the EC SynEx
Project.
This report, although a final report as far as the EC project is concerned, is really a
description of the first phase in establishing a centre of healthcare excellence. New
EC Fifth Framework project funding has already been approved to enable new and
innovative technology solutions to be added to the work already established in north
