NeuroZika: The history of how the mosquito helped to reduce the scientific gap in a developing country
Full text linkYes! The mosquito did it again. Since the beginning of the current Zika virus outbreak in 2016, 3-4 million adults have been infected, a subset of which has suffered severe neurological complications. This raised multiple questions about how arboviruses, a traditional cause of mosquito-borne infection, may impact both the human brain structure and functional organization. The Dominican Republic, endemic for mosquitoborne diseases, was one of the most affected countries. With the support of the University of Illinois at Urbana Champaign, our lab was able to develop a collaboration with the Dominican Republic that allowed us to conduct the first case-control neuroimaging study in an adults suffering from Zika virus with severe neurological manifestations. Beyond the informative value of this study for the clinical and scientific community, this project fostered a collaborative environment that have allowed multiple Dominican health professionals to be trained and exposed to the high level research conducted at UIUC, therefore expanding the horizons of the science and reducing the unfortunate gap between developed and developing countries. This is the history of how the mosquito contributed to wake up the scientific spirit of this, otherwise dormant, Caribbean paradise.Open Restriction set for Item 105757 on 2018-04-23T15:27:51Z with date null by [email protected] by Emilie Staubs ([email protected]) on 2018-04-23T15:29:49Z

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
Fusion de données EEG-IRMf et IRMd chez des sujets sains et des patients atteints d'épilepsie du lobe temporal : vers une caractérisation trimodale du réseau structure-fonction du cerveau humain
No full textLa caractérisation de la structure du cerveau humain et les motifs fonctionnelles qu’il fait apparaitre est un défi central pour une meilleure compréhension des pathologies du réseau cérébral telle que l’épilepsie du lobe temporal. Cette caractérisation pourrait aider à améliorer la prédictibilité clinique des résultats d’une chirurgie visant à traiter l’épilepsie.Le fonctionnement du cerveau peut être étudié par l’électroencéphalographie (EEG) ou par l’imagerie de résonance magnétique fonctionnelle (IRMf), alors que la structure peut être caractérisé par l’IRM de diffusion (IRMd). Nous avons utilisé ces modalités pour mesurer le fonctionnement du cerveau pendant une tache de reconnaissance de visages et pendant le repos dans le but de faire le lien entre les modalités d’une façon optimale en termes de résolution temporale et spatiale. Avec cette approche on a mis en évidence une perturbation des relations structure-fonction chez les patients épileptiques.Ce travail a contribué à améliorer la compréhension de l’épilepsie comme une maladie de réseau qui affecte le cerveau à large échelle et non pas au niveau d’un foyer épileptique local. Dans le futur, ces résultats pourraient être utilisés pour guider des interventions chirurgicales mais ils fournissent également des approches nouvelles pour évaluer des traitements pharmacologiques selon ses implications fonctionnelles à l’échelle du cerveau entier.The understanding human brain structure and the function patterns arising from it is a central challenge to better characterize brain network pathologies such as temporal lobe epilepsies, which could help to improve the clinical predictability of epileptic surgery outcome.Brain functioning can be accessed by both electroencephalography (EEG) or functional magnetic resonance imaging (fMRI), while brain structure can be measured with diffusion MRI (dMRI). We use these modalities to measure brain functioning during a face recognition task and in rest in order to link the different modalities in an optimal temporal and spatial manner. We discovered disruption of the network processing famous faces as well a disruption of the structure-function relation during rest in epileptic patients.This work broadened the understanding of epilepsy as a network disease that changes the brain on a large scale not limited to a local epileptic focus. In the future these results could be used to guide clinical intervention during epilepsy surgery but also they provide new approaches to evaluate pharmacological treatment on its functional implications on a whole brain scale
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
