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
Estudio integral del riesgo de desastres por deslizamiento en las microcuencas Alto Peú y San Martín - Cerro La Picota - Ayacucho
No full textEl Perú posee una riqueza invaluable en recursos naturales gracias a que presenta una geografía por demás diversa. Estos mismos atributos también configuran espacios geográficos propensos a desastres naturales, como es el caso de la microcuenca Alto Perú y San Martín ubicados en el distrito de Ayacucho. El estudio realizado tuvo como objetivo general, determinar los niveles de riesgo de desastre por deslizamiento en las microcuencas de Alto Perú y San Martín, que permita a las autoridades y responsables del Gobierno Regional y Municipal, implementar estrategias orientadas a reducir el impacto y la vulnerabilidad por desastre de esta parte de la ciudad. La metodología de investigación asumida para la realización de este estudio se ciñe a los lineamientos metodológicos de la investigación cuantitativa, en la medida que se utilizó el diseño descriptivo correlaciona! para comprobar las hipótesis investigativas formuladas. La muestra de estudio estuvo conformada por 320 lotes ubicados en la micro cuenca de Alto Perú y San Martín, registrados en una base de datos, bajo los criterios de riesgo muy alta, alta, media, baja y muy baja. Las técnicas e instrumentos para el recojo de información consideró herramientas tecnológicas como es el caso de las técnicas de teledetección y los sistemas de información geográfica (SIG), así como información documental registrada en instituciones responsables de velar por la seguridad de la población. Los resultados obtenidos en el estudio demuestran que existe correlaCión directa y significativa entre niveles de riesgo y las dimensiones de peligro y vulnerabilidad, en la medida que el coeficiente de correlación es 0.895, con un nivel de significancia del 1% y un intervalo de confianza del 95%. Palabras clave: Riesgo de desastre, deslizamiento, peligro, vulnerabilidad xiii ABSTRACT Peru has an invaluable wealth of natural resources by presenting a diverse geography others. These same attributes also shape prone to natural disasters geographical areas, such as the micro watershed Alto Peru and San Martín located in the district of Ayacucho. The study had overall objective is to determine levels of disaster risk sliding into the micro basins of Alto Peru and San Martín, which allows authorities and officials of Regional and Municipal Government, implement targeted strategies to reduce the impact and disaster vulnerability of this area of the city. The research methodology assumed for this study is limited to the methodologicat guidelines of quantitative research, to the extent that the descriptiva correlational design was used to test the investigative assumptions made. The study sample consisted of 320 lots located in the micro watershed Alto Peru and San Martín, recorded in a database under the standards very high, high, medium, low and very low risk. The techniques and tools for information gathering considerad technological tools such as remote sensing techniques and geographic information systems (CIS) and documentary information recorded in charge of ensuring the safety of public institutions. The results obtained in the study demonstrate significant and direct correlation between risk of sliding and disaster warning size and vulnerability, as the correlation coefficient is 0.895, with a significance level of 1% and a range of 95% confidence.

No full textAuthor, 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

Mining e-mail content for author identification forensics
No full textWe describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different email topics. An extended set of e-mail document features including structural characteristics and linguistic patterns were derived and, together with a Support Vector Machine learning algorithm, were used for mining the e-mail content. Experiments using a number of e-mail documents generated by different authors on a set of topics gave promising results for both aggregated and multi-topic author categorisation
