Choices and consequences of oviposition by a pollinating seed predator,Hadena ectypa(Noctuidae), on its host plant,Silene stellata(Caryophyllaceae)
Authors: Kula Abigail A. R. , Dudash Michele R. , Fenster Charles B. 
Published: May 2013

•Premise of the study:Pollinating seed predators are models for the study of mutualisms. These insects have dual effects on host‐plant fitness, through pollination as adults and flower and fruit predation as larvae. A rarely examined question is whether pollinating seed‐predator oviposition choices are influenced by plant floral and size traits and the potential consequences of oviposition for host‐plant reproduction.•Methods:We quantified oviposition by a pollinating seed predator,Hadena ectypa, on its host,Silene stellata, to determine if oviposition was associated with specific plant traits and whether oviposition was significantly correlated with fruit initiation or flower and fruit predation over three years. We also quantified whether stigmatic pollen loads of flowers visited byHadenathat both fed on nectar and oviposited were greater than whenHadenaonly fed on nectar.•Key Results: Hadenahad significant preference for plants having flowers with long corolla tubes in all three years. Moth oviposition was correlated with other traits only in some years. Oviposition did not increase stigmatic pollen loads. We observed significant positive relationships between both oviposition and fruit initiation and oviposition and flower/fruit predation.•Conclusions: Hadena ectypaoviposition choices were based consistently on floral tube length differences among individuals, and the consequences of oviposition include both fruit initiation (due to pollination while feeding on nectar prior to oviposition) and larval flower/fruit predation. The positive association between oviposition and fruit initiation may explain the long‐term maintenance of facultative pollinating seed‐predator interactions.
Spanish scientific output in communication sciences in WOS. The scientific journals in SSCI (2007-12)
Authors: de-Filippo Daniela 
Published: May 2013

Although the field of Communication Sciences has been slower to organize in Spain than in other European countries and the United States, in recent years it has shown a clear tendency to growth. One way to trace this process is by analyzing scientific production, and this paper focuses on this aspect. Using bibliometric methods, we analyze scientific journals and papers indexed in Thomson Reuter’s international database, the Social Science Citation Index (SSCI) for Communication. While the focus of the study is Spanish scientific output, the results are related to international activities in this field. The three Spanish journals included in SSCI in recent years: «Comunicar», «Comunicación y Sociedad» and «Estudios sobre el Mensaje Periodístico» were studied in detail. The results show that Spain plays an important role in Communcation journal publishing (4th in the world) and as a producer of scientific papers (6th in the world), with a remarkable evolution, in quantitative terms, especially in the last five years. The inclusion of these three Spanish journals in the international database has been an important contribution to the country's visibility in this field, but there is still a need to promote international collaboration to achieve greater impact and openness in the scientific community.
Aunque el campo de las Ciencias de la Comunicación en España ha tenido una organización más tardía que en otros países de Europa y Estados Unidos, en los últimos años ha evidenciado un claro proceso de crecimiento. Una forma de rastrear este proceso es a través del análisis de la producción científica, por lo que este trabajo se centra en este aspecto. Utilizando métodos bibliométricos se estudian las revistas y los documentos publicados en la base de datos internacional Social Science Citation Index (SSCI) de Thomson Reuters en la disciplina Communication. Si bien el foco es el estudio de la producción española, los resultados se ponen en relación con la actividad internacional en este campo. En cada caso se analizan con mayor detalle las tres revistas españolas incluidas en SSCI en los últimos años: «Comunicar», «Comunicación y Sociedad» y «Estudios sobre el Mensaje Periodístico». Los resultados obtenidos muestran un importante papel de España como editor de revistas sobre Comunicación (4º del mundo) y como productor de artículos (6º del mundo) con una notable evolución en términos cuantitativos en los últimos cinco años. La inclusión de las tres revistas españolas en la base de datos internacional ha sido una importante contribución a la visibilidad del país en esta disciplina, aunque aún es necesario promover la colaboración internacional para lograr un mayor impacto y apertura a la comunidad científica.
Internationalization and coauthorship in major communication journals in Spain
Authors: Escribà-Sales Eudald , Cortiñas Sergi 
Published: May 2013

This work has conducted an analysis of Spanish Communication journals in terms of their level of internationalization and the collaborative models used by their authors, by assessing 1,182 articles published between 2007 and 2011 in the seven toprated Communication journals according to a set of six quality indicators. The ultimate goal has been to perform a data processing in order to detect the degree of inclination of international authors to publish their works in Spanish journals in the years covered by this study. Secondly, the study draws a profile of coauthorship patterns focused on geographical and institutional alliances. The results show there is no clear and convincing signs of evolution towards a desired level of internationality. Concerning coauthorship, although the results indicate a willingness on the part of authors to chart a path of wider geographical and institutional collaboration, unique authorship continues to be the preferred form of publication. Finally, the work shows that investigative alliances are confined to Spain and when they go international collaborations are almost exclusively with Latin American authors.
En este estudio se ha llevado a cabo un análisis de las revistas científicas de Comunicación españolas en términos de su grado de internacionalización y de los modelos colaborativos utilizados por sus autores. Para ello se han analizado un total de 1.182 artículos publicados entre 2007 y 2011 por las siete revistas españolas mejor valoradas en términos de calidad. El objetivo principal ha sido realizar un tratamiento de los datos con el fin de observar si en los años comprendidos en el estudio se ha producido un incremento del interés de autores internacionales por publicar en las revistas españolas. En segundo lugar, se ha dibujado un perfil de los patrones que rigen las coautorías en términos geográficos y de alianzas institucionales. Los resultados no han permitido apreciar síntomas de evolución hacia los grados de internacionalidad deseados. Por lo que se refiere a las coautorías, aunque se percibe una voluntad por parte de los autores de trazar un camino de mayor colaboración institucional y geográfica, se observa que sigue predominando la autoría única y que las alianzas se concentran dentro del territorio español y se opta casi exclusivamente por Latinoamérica cuando se trata de llevar a cabo colaboraciones internacionales.

Published: May 2013

In this paper we review the socalled altmetrics or alternative metrics. This concept raises from the development of new indicators based on Web 2.0, for the evaluation of the research and academic activity. The basic assumption is that variables such as mentions in blogs, number of twits or of researchers bookmarking a research paper for instance, may be legitimate indicators for measuring the use and impact of scientific publications. In this sense, these indicators are currently the focus of the bibliometric community and are being discussed and debated. We describe the main platforms and indicators and we analyze as a sample the Spanish research output in Communication Studies. Comparing traditional indicators such as citations with these new indicators. The results show that the most cited papers are also the ones with a highest impact according to the altmetrics. We conclude pointing out the main shortcomings these metrics present and the role they may play when measuring the research impact through 2.0 platforms.
En el presente trabajo se realiza una revisión de las altmetrics o indicadores alternativos. Este concepto se define como la creación y estudio de nuevos indicadores, basados en la web 2.0, para el análisis de la actividad científica y académica. La idea que subyace es que, por ejemplo, las menciones en blogs, el número de tuits o el de personas que guardan un artículo en su gestor de referencias puede ser una medida válida del uso y repercusión de las publicaciones científicas. En este sentido, estas medidas se han situado en el centro del debate de los estudios bibliométricos cobrando especial relevancia. En el artículo se ilustran en primer lugar las plataformas e indicadores principales de este tipo de medidas, para posteriormente estudiar un conjunto de trabajos del ámbito de la comunicación, comparando el número de citas recibidas con sus indicadores 2.0. Los resultados señalan que los artículos más citados de la disciplina en los últimos años también presentan indicadores significativamente más elevados de altmetrics. Seguidamente se realiza un repaso por los principales estudios empíricos realizados, deteniéndonos en las correlaciones entre indicadores bibliométricos y alternativos. Se finaliza, a modo de reflexión, señalando las principales limitaciones y el papel que las altmetrics pueden desempeñar a la hora de captar la repercusión de la investigación en las plataformas de la web 2.0.
Spanish communication academia: Scientific productivity vs. Social activity
Authors: Casanueva-Rocha Cristóbal , Caro-González Francisco-Javier 
Published: May 2013

At a time when academic activity in the area of communication is principally assessed by the impact of scientific journals, the scientific media and the scientific productivity of researchers, the question arises as to whether social factors condition scientific activity as much as these objective elements. This investigation analyzes the influence of scientific productivity and social activity in the area of communication. We identify a social network of researchers from a compilation of doctoral theses in communication and calculate the scientific production of 180 of the most active researchers who sit on doctoral committees. Social network analysis is then used to study the relations that are formed on these doctoral thesis committees. The results suggest that social factors, rather than individual scientific productivity, positively influence such a key academic and scientific activity as the award of doctoral degrees. Our conclusions point to a disconnection between scientific productivity and the international scope of researchers and their role in the social network. Nevertheless, the consequences of this situation are tempered by the nonhierarchical structure of relations between communication scientists.En un momento en que la actividad académica en el ámbito de la comunicación se valora principalmente por el impacto de las revistas y los medios de comunicación científica y por la productividad de los investigadores, surge la cuestión de si los factores sociales pueden condicionar la actividad científica con la misma fuerza que estos elementos objetivos. Esta investigación analiza la influencia de la productividad científica y de la actividad social en el ámbito de la comunicación. Se ha identificado la red social de los investigadores de comunicación a partir de las tesis doctorales. Para los 180 investigadores más activos en los tribunales de tesis se ha calculado su producción científica. Se utiliza el análisis de redes sociales para estudiar las relaciones que se producen en los tribunales de tesis doctorales. Los resultados muestran que los factores sociales influyen positivamente en una actividad académica y científica tan relevante como la obtención del grado de doctor, mientras que la productividad científica individual no lo hace. Como conclusiones cabe señalar que existe una desconexión entre la productividad científica y la proyección internacional de los investigadores y su papel en la red social. Las implicaciones de este hecho están matizadas por una estructura no jerarquizada de las relaciones entre los científicos de comunicación.
The videoarticle: New reporting format in scientific journals and its integration in MOOCs
Authors: Vázquez-Cano Esteban 
Published: May 2013

The new training context in higher education is moving toward a new model of massive, open and free education through a methodology based on video simulation and students’ collaborative work. Using a descriptive methodology, we analyze the formats and Web content presentation of 72 journals indexed in the Journal Citation Reports® (2013) in the field of communication, and their presence in the development of massive open online courses (MOOCs) at the leading global platform, «Coursera». The findings show that the vast majority of scientific journals in the field of communication offer few disclosure formats and are difficult to embed in new massive, ubiquitous and collaborative movements which use the selfcreated «audiovisual pill». Therefore, the integration of articles of international scientific journals in MOOCs is almost nonexistent. Journals are not taking advantage of the great potential of these courses for scientific divulgation, probably because its unique disclosure format is written text. Thus, we propose a new model for scientific publication which shares writing text format with the video article, social media outreach and new formats supported by mobile digital devices to foster greater international visibility of scientific development and social progress in an everyday, more interconnected and visual society.
Los nuevos escenarios formativos en la educación superior se están orientando hacia un nuevo modelo de formación masiva, abierta y gratuita por medio de una metodología basada en la videosimulación y el trabajo colaborativo del estudiante. En este artículo analizamos a través de un estudio descriptivo los formatos de divulgación y presentación de contenidos de las 72 revistas indexadas del campo de la Comunicación en el Journal Citation Reports® (2013) y su presencia en el desarrollo de cursos online masivos en abierto (MOOCs) en la principal plataforma mundial «Coursera». Las conclusiones muestran que la gran mayoría de revistas científicas del campo de la Comunicación ofrecen pocos formatos de divulgación y poco integrables en los nuevos movimientos masivos, ubicuos y colaborativos que utiliza como recurso principal, la «píldora audiovisual» de creación propia. El posicionamiento de las revistas de reconocido prestigio internacional es casi nulo y no se está aprovechando el gran potencial que estos cursos suponen para la divulgación científica; probablemente debido a que su único formato de divulgación es el texto escrito. Como consecuencia de esta situación, proponemos un nuevo modelo de divulgación científica que comparta el soporte escrito con el videoartículo, la divulgación en redes sociales y la difusión en formatos soportados por dispositivos digitales móviles que favorezcan una mayor visibilidad internacional del avance científico y social de manera más integrada en la sociedad interconectada y visual en la que vivimos.
Ethos, pathos and logos in Facebook. User networking: New «rhetor» of the 21th century
Authors: Berlanga-Fernández Inmaculada , García-García Francisco , Victoria-Mas Juan-Salvador 
Published: May 2013

One of the «black holes» of academic research in Communication is the shallowness of reflections on the classic origins of Communication, its aims and points of entry. In this respect, the study of communicative processes on the Internet becomes particularly relevant (specifically the social networks processes) when observed from the classic rhetorical perspective. We focus on the use of persuasion strategies (ethos, pathos, logos) as well as the abundant use of rhetorical figures. Such parameters, along with the resources that emergent technologies offer, unleash creativity and afford humanist aspects to network communication. These give online platforms an extremely persuasive strength. Thus, we may speak of the network user of the 21st century as the new «Rhetorician». Our research on Facebook addresses the presence of rhetoric in online social network communication: the user of these platforms applies communicative strategies described by the Rhetoricians dating back to GrecoRoman antiquity. The methodology in this work (the study of three typified cases and the content analysis of conversations generated on Facebook walls) allows us to intertwine rhetoric and communication today, mediated by the emergence of online networks. We propose the retrieval of certain parameters of deep, critical thought to the benefit of a more human communication.
Uno de los «agujeros negros» de la investigación en comunicación tiene que ver con una carencia de profundización en los orígenes clásicos de nuestros estudios, de sus objetos y de los acercamientos a estos. En este sentido, cobraría especial relevancia el estudio de los procesos comunicativos en Internet (en concreto a través de las redes sociales) bajo el prisma de la Retórica clásica. Especialmente, nos referimos al uso de las estrategias de persuasión (ethos, pathos, logos) así como al abundante uso de figuras retóricas. Tales parámetros unidos a los recursos que ofertan las tecnologías emergentes otorgan una enorme creatividad y aportan aspectos humanistas a la comunicación en red, claves de la fuerza persuasiva que caracteriza a estas plataformas online. De esta forma podemos hablar del usuario de redes como el nuevo «rétor» del siglo XXI. Nuestra investigación sobre Facebook aborda la presencia de la ciencia retórica en la comunicación generada en las redes sociales online: el usuario de estas plataformas utiliza las estrategias comunicativas descritas por la disciplina retórica desde sus comienzos en la antigüedad grecolatina. La metodología empleada (el estudio de tres casos tipificados y el análisis de contenidos de las conversaciones generadas en los muros de Facebook) nos permite entrelazar la Retórica y nuestro presente comunicativo mediado por la emergencia de las redes. Proponemos así recuperar unos parámetros que devuelvan el pensamiento profundo y crítico en favor de una comunicación más humana.
LIGHT (TNFSF14/CD258) Is a Decisive Factor for Recovery from Experimental Autoimmune Encephalomyelitis

Abstract
The TNF superfamily ligand LIGHT (lymphotoxin-like, exhibits inducible expression and competes with HSV glycoprotein D for herpesvirus entry mediator [HVEM], a receptor expressed by T lymphocytes) has been shown to play a role in T cell costimulation and be involved in apoptosis of mononuclear cells. As both T cells and monocytes are key components in the development and progression of experimental autoimmune encephalomyelitis (EAE), we studied the role of LIGHT in EAE. Following immunization with myelin oligodendrocyte glycoprotein peptide (35–55), LIGHT-deficient mice developed severe EAE that resulted in an atypically high mortality rate. Histological examinations revealed intensive activation of microglia/macrophages in the CNS and higher numbers of apoptotic cells within the CNS parenchyma of LIGHT-deficient mice. However, myelin oligodendrocyte glycoprotein peptide–specific CD4+ T cells from LIGHT-deficient mice showed reduced IFN-γ and IL-17 production and migration. Serum levels of reactive nitrogen intermediates and CNS transcripts of several proinflammatory cytokines and chemokines were also substantially decreased in the absence of LIGHT. EAE adoptive transfer experiments and bone marrow chimeras indicated that expression of LIGHT on donor cells is not required for disease induction. However, its expression on CNS host cells is a decisive factor to limit disease progression and tissue damage. Together, these data show that LIGHT expression is crucially involved in controlling activated macrophages/microglia during autoimmune CNS inflammation.
The Bacterial Quorum-Sensing Signal Molecule N-3-Oxo-Dodecanoyl-l-Homoserine Lactone Reciprocally Modulates Pro- and Anti-Inflammatory Cytokines in Activated Macrophages

Abstract
The bacterial molecule N-3-oxo-dodecanoyl-l-homoserine lactone (C12) has critical roles in both interbacterial communication and interkingdom signaling. The ability of C12 to downregulate production of the key proinflammatory cytokine TNF-α in stimulated macrophages was suggested to contribute to the establishment of chronic infections by opportunistic Gram-negative bacteria, such as Pseudomonas aeruginosa. We show that, in contrast to TNF-α suppression, C12 amplifies production of the major anti-inflammatory cytokine IL-10 in LPS-stimulated murine RAW264.7 macrophages, as well as peritoneal macrophages. Furthermore, C12 increased IL-10 mRNA levels and IL-10 promoter reporter activity in LPS-stimulated RAW264.7 macrophages, indicating that C12 modulates IL-10 expression at the transcriptional level. Finally, C12 substantially potentiated LPS-stimulated NF-κB DNA-binding levels and prolonged p38 MAPK phosphorylation in RAW264.7 macrophages, suggesting that increased transcriptional activity of NF-κB and/or p38-activated transcription factors serves to upregulate IL-10 production in macrophages exposed to both LPS and C12. These findings reveal another part of the complex array of host transitions through which opportunistic bacteria downregulate immune responses to flourish and establish a chronic infection.
Laboratory Diagnosis of Malaria: Conventional and Rapid Diagnostic Methods
Authors: Wilson Michael L. 
Published: May 2013

Context.—The global control of malaria is more challenging than that of many other infectious diseases: malaria is vector borne, it is caused by 5 species of Plasmodium with different geographic distributions, infection is widespread in many regions, drug resistance is common, and the disease overlaps clinically with other infectious diseases. Therefore, malaria control programs, in addition to diagnosis and testing, must also target limiting spread of the disease through vector control. Although malaria control efforts have been successful in some regions, malaria remains one of the most important causes of death in sub-Saharan Africa, particularly in women and children.
Objective.—To review the current literature regarding diagnostic methods available to detect clinical malaria, with an emphasis on comparing the strengths and limitations of each method.
Data Sources.—Current World Health Organization malaria control report and other information, recent meta-analyses of diagnostic tests, primary literature concerning the performance characteristics of different tests, and primary literature concerning how diagnostic tests are used in daily practice.
Conclusions.—The most commonly used method for identifying cases of malaria remains microscopic examination of peripheral blood, but there is growing use of malaria rapid diagnostic tests in many regions. One of the most important findings in the recent literature is that despite the widespread use of diagnostic tests, treatment is too often based on clinical findings rather than on results of diagnostic tests.
