Nefropat\ueda y retinopat\ueda diab\ue9ticas
La neuropat\ueda y la retinopat\ueda diab\ue9ticas son, de modo debatible, las dos complicaciones m\ue1s temidas de la diabetes. Juntas contribuyen a morbilidad v mortalidad graves. Conforme avanzan a nefropat\ueda en etapa terminal y a ceguera. imponen enormes costos m\ue9dicos, econ\uf3micos y sociales, tanto en los pacientes como en el sistema de atenci\uf3n a la salud. Dado que la nefropat\ueda y la retinopat\ueda se relacionan a menudo entre s\ued en los pacientes, este art\uedculo revisa los aspectos comunes y por separado de la fisiopatolog\ueda. el cuadro cl\uednico y el tratamiento
Micro droplets generated on a rising bubble through an oppositely charged oil/water interface
The mass transfer between immiscible two-liquid phases can be greatly enhanced by bubbling gas through a reactor. Numerous micro water droplets breaking out from a ruptured water film around a rising bubble through the oil (upper phase)/water (lower phase) interface were demonstrated in the preceding paper (Uemura T., Ueda Y. and Iguchi M., Europhys. Lett., 92(2010)34004). In this letter, we attempt to oppositely charge the oil and water layers, taking into account the findings of the preliminary study (Uemura T., Ueda Y. and Iguchi M., J. Visualization, 13(2010)85). As a result, this study successfully produces more and finer water droplets than the preceding experiments

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
Modelos de Programas de Auditor\ueda y Cuestionarios de Control Interno para Empresas Comerciales
La Auditor\ueda como rama de la Contabilidad General, ha venido con el transcurso del tiempo evolucionando \uf3 experimentando cambios derivados por la coyuntura hist\uf3rica que se est\ue1 viviendo, de tal manera su objetivo inicial de evaluar la conducta y rectitud de los funcionarios que ten\uedan responsabilidades en el gobierno o en el comercio y luego descubrimientos de fraudes, pasa a ser el de determinar la razonabilidad o no de los Estados Financieros de una empresa. Es all\ued donde juega un papel fundamental la figura del Auditor Independiente en el desarrollo de una Auditor\ueda, deben elaborar y adecuar los programas de Auditor\ueda y Cuestionarios de Control Interno de acuerdo a las normas de aceptaci\uf3n general. Se presentan modelos de Programas de Auditor\ueda y Cuestionarios de Control Interno que pueden servir de gu\ueda en la realizaci\uf3n de una Auditor\ueda y orientar el dise\uf1o de los mismos
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
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
Bolet\uedn de Mariolog\ueda y Salud Ambiental
El Bolet\uedn de la Direcci\uf3n de Malariolog\ueda y Saneamiento Ambiental es una publicaci\uf3n editada por la antigua "Escuela de Malariolog\ueda", ahora Servicio Aut\uf3nomo Instituto de Altos Estudios \u93Dr. Arnoldo Gabaldon\u94 (IAES), desde el a\uf1o 1961. Su editor fundador, el Dr. Arnoldo Gabaldon es reconocido por su exitosa labor en el control de la enfermedad end\ue9mica de mayor importancia en el pa\ueds para la \ue9poca, la malaria.
Desde los primeros n\ufameros, se publican art\uedculos originales y/o revisiones relacionadas con Parasitolog\ueda, Medicina Tropical, Entomolog\ueda M\ue9dica, Epidemiolog\ueda y Control, Inmunolog\ueda, Ingenier\ueda Sanitaria, Saneamiento Ambiental, Educaci\uf3n Sanitaria y Ciencias Sociales.
En el a\uf1o 2003, la revista sufre modificaciones tanto en su presentaci\uf3n, como en el Comit\ue9 Editorial, en pro de mejorar su calidad, adem\ue1s de estrenar un nuevo t\uedtulo \u93Bolet\uedn de Malariolog\ueda y Salud Ambiental\u94.
Esta revista, al igual que muchas otras publicaciones latinoamericanas, en su 45 a\uf1os de existencia, ha afrontado dificultades para garantizar su periodicidad. Sin embargo, gracias al empe\uf1o y dedicaci\uf3n de su cuerpo editorial, ha logrado mantenerse en el tiempo y hoy por hoy, es una publicaci\uf3n reconocida internacionalmente, fuente de consulta de investigadores, gerentes y personal t\ue9cnico, indizada en la base de datos de Literatura Latinoamericana Cient\uedfica en Salud (LILACS) <http://www.bireme.br/abd/P/lista_pais.htm> de BIREME, Global Health <http://www.globalhealth-database.org/>, Latindex <http://www.latindex.unam.mx/> y registrada en la Asociaci\uf3n de Editores de Revistas M\ue9dicas (ASEREME) <http://www.asereme.org.ve
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
