Knowledge gained by pediatric residents after neonatal resuscitation program courses
No full textBackground: The efficacy of the Neonatal Resuscitation Program (NRP) courses was previously evaluated, demonstrating good retention of knowledge in the participants. However, there is a lack of information regarding the participants' performance in relation to the different steps of neonatal resuscitation. We aimed to assess the knowledge gained and retained by pediatric residents who participated in a NRP course in relation to the different steps. Methods: An 80-item questionnaire derived from the standard test contained in the American Heart Association and American Academy of Pediatrics Neonatal Resuscitation Manual was given to 25 pediatric residents before, immediately after and 6 months after the course. Results: The percentages of correct answers significantly improved from before (37.6 ± 3.1%) to immediately after the course (94.1 ± 0.9%) (P < 0.001). The percentages at the 6 months follow-up test (62.7 ± 2.2%) significantly decreased from posttest (P < 0.001), but remained significantly higher with respect to pretest performance (P < 0.001). The percentages of correct answers were different among the four neonatal resuscitation steps during the entire study (pretest, posttest and follow-up test). Conclusions: The knowledge gained by pediatric residents participating in the NRP course was very high, but was only partially retained over time. In particular, it was different among the four steps of neonatal resuscitation suggesting further studies on teaching resuscitation. © 2005 Blackwell Publishing Ltd
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Fluid geochemistry of Lessini Mountain's thermal area: New data from Caldiero, S. Ambrogio-Colà di Lazise and Sirmione hydrothermal districts (Verona-Brescia Provinces, Italy)
No full textThe Po Plain, located in northern Italy between the Alps and the Apennines, hosts several thermal water spots. Some of these thermal waters belong to the thermal districts of Brescia and Verona provinces. This thermalism has been used for therapeutical purposes since the "Roman Age ". During Sept. 2014 - Aug. 2015, a detailed sampling program was carried out to collect water samples of thermal and cold waters in the Lessini Mountain's thermal area, including those in the Sirmione thermal district (project area). Assessment of water chemistry and isotope data, identified distinctive characteristics of thermal waters belonging to the thermal districts investigated in this project (i.e. Caldiero, S.Ambrogio Valpolicella, Cola di Lazise, Lazise and Sirmione). In particular, data show that the Sirmione thermal waters are characterized by a higher temperature and a total salinity and by chemical and isotopic fingerprints that are distinct and unrelated to those of other thermal waters. On the other hand, the data indicate potential correlations between samples from S.Ambrogio Valpolicella and Cola di Lazise and local cold water. Geochemical modeling conducted using PHREEQC, showed that a mixing accompanied by calcite precipitation can explain the chemical characteristics observed in the thermal waters and some cold springs assessed in this project. New geothermometric estimations were performed for main thermal components, obtaining temperature ranges (in degrees C) of about 92-99, 67-74 and 51-58, respectively for Sirmione, S. Ambrogio Valpolicella-Cola di Lazise and Caldiero thermal districts. Temperature ranges obtained in this work were used to gain an insight into the possible depth reached by thermal waters in the project area, which is characterized by the normal geothermal gradient (30 degrees C/Km). Finally, geochemical findings were elaborated and integrated with geological and structural data in a proposed conceptual model of water circulation. The agreement within data sets is satisfactory in particular in relation to the depth of carbonate-evaporite formations, which represent the thermal reservoirs. Infiltrating waters can seep into the deep through fractured rocks, reaching the Carnian to Upper Cretaceous carbonates and evaporites. In the Caldiero thermal districts the depth reached by thermal waters coincides with the level of the Carnian evaporites (approximate to 1.3-1.6 Km) and it agrees with the important role played by dissolved sulphates evidenced by geochemical data. Thermal fluids in Sirmione and S. Ambrogio Valpolicella - Cola di Lazise thermal districts likely interact with Permian-Middle Triassic formations, which are located at greater depths (approximate to 2.7-3 Km and approximate to 1.9-2.1 Km, respectively). Once heated at depth, thermal fluids rise through main faults and/or thrust faults, where they may be diluted by circulating surface cold waters
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
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
