Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
In this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Control del dolor en el aborto quirúrgico durante el primer trimestre: comentario de la BSR
Los resultados de esta revisión se basan en estudios de escasa magnitud que evaluaron una variedad de intervenciones. Sugieren que la sedación consciente, la anestesia general y algunas intervenciones no farmacológicas probablemente sean seguras y útiles para disminuir el dolor durante y después del procedimiento; además, las pacientes califican estas intervenciones como satisfactorias. Los estudios disponibles sobre bloqueo paracervical examinaron varios aspectos de la técnica, pero los datos fueron insuficientes como para recomendar su uso.http://apps.who.int/rhl/fertility/abortion/CD006712_chengl_com/es/index.htm
Objektorientierte Datenbanken in der Hydrologie: Anwendungsbeispiel OMS Banques de données orientées objet dans le domaine de l'hydrologie : exemple d'application OMS
Mit dem Object Modeling System (OMS) ist die Modellkonstruktion und Modellausführung für eine Vielzahl von Umweltprozessen im Anwendungsfeld der Geohydrologie möglich. Die auf objektorientierter Technologie basierende Datenbankkomponente des OMS versucht die riesigen Datenmengen, die für eine ausreichend befriedigende Umweltsimulation notwendig sind, effektiv zu verwalten und zu verarbeiten. Inhalt des vorliegenden Beitrags ist die Darstellung des Entwurfs und der Realisierung einer Datenbankschnittstelle für das OMS unter Berücksichtigung der Anwendung in der hydrologischen Modellierung.
The Object Modelling System (OMS) represents a flexible tool for controlling model construction and execution in geohydrological application domains. The integrated database management component of OMS is handling, managing and processing large scale data sets for environmental simulations. The emphasis in this paper is given onto the design and implementation of an object-oriented interface for data management with primary focus to its application in hydrological modelling and simulation

Dispelling the Myths Behind First-author Citation Counts
We 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
Diferencias en magnitud de estado nutricional en escolares chilenos según la referencia CDC y OMS 2005-2008
Introducción: Es necesario realizar nuevas discusiones respecto a la magnitud de los problemas nutricionales diagnosticados, al usar CDC u OMS, frente a la existencia de nuevas definiciones biológicas o estadísticas de obesidad. Objetivo: Comparar la evolución de la prevalencia de estado nutricional en escolares de primero básico, desde el año 2005 al 2008, según CDC y OMS. Métodos: Cohorte retrospectiva, de 140.265 escolares de ambos sexos de primero básico, evaluados entre 2005-2008, cuyos datos antropométricos (peso y talla), se obtuvieron del sistema anual de registro del estado nutricional escolar. Para clasificar el estado nutricional, se utilizaron los patrones CDC y OMS. Resultados: Los promedios de IMC fueron levemente diferentes y menores en la niñas que en los niños, en 2005 y 2006. Durante el 2007 y 2008 el promedio de IMC en las niñas alcanzó la cifra observada en los varones. Hubo mayor prevalencia de bajo peso según OMS (p=0,03), con una tendencia a la disminución en los años posteriores. La prevalencia de normalidad fue mayor según el criterio CDC, con una reducción entre el 2005 y 2007 y un incremento 2008 (p<0,001). Hubo una menor prevalencia de sobrepeso según el criterio CDC (p<0,001), con aumento entre el 2005 y 2007, tanto CDC como OMS. La prevalencia de obesidad fue menor según el criterio OMS, no encontrándose diferencia estadísticamente significativa al comparar con el patrón CDC. Conclusiones: Al comparar ambos patrones, CDC tiende a sobreestimar la normalidad y subestimar el sobrepeso, mientras que en obesidad no se encontraron diferencias significativas
