Emerging trends on satellite-based applications in health: a synoptic view
Full text linkThis study examines the state of the art of satellite-based applications for human health. It deepens the main drivers and barriers to their diffusion and full-scale development. Living in a more globalised, intertwined, and technologically advanced world has opened the door to a more digital health system able to connect many actors, reach remote locations, and provide coverage at a global level, whose exploitation has become even more urgent due to the Covid-19 pandemic. Space technologies may be a valid asset to tackle future health challenges. Despite the clear linkage of the two domains, the literature lacks a holistic view of the phenomenon of the current adoption of space assets in the health domain. Moreover, the factors that limit or foster the development of satellite-based applications in health management and healthcare delivery are still unclear and require a thorough investigation. The framework on the relationship between space activities and global health applications elaborated by the United Nations Office for Outer Space Affairs has been adapted and populated with 86 business-cases gathered from a systematic literature review of the ESA public database. The findings were analysed to provide a comprehensive and in-depth view of the most relevant trends. The joint combination of satellite and digital technologies appears as the enabling factor to provide an effective service to professional end-users and improve the quality of health for patients. The importance of data integration from multiple satellite technologies and additional data is highlighted in many projects as the key success factor for developing effective applications. In addition, the technical, economic, organisational, socio-cultural, and political factors were explored in terms of barriers to or opportunities for the adoption of satellite-based applications for health. To this end, further information was gathered through a systematic literature review of 89 scientific articles and interviews with 8 internationally recognised experts. Results show how multiple factors could hamper the diffusion and success of the emerging applications, and how those factors should inform strategic decisions to foster the development of satellite-based applications in the future. This study may benefit academics, practitioners and public institutions to grasp the benefits and challenges in adopting satellite and geospatial data in health. It provides a systematic overview of the existing practices, highlighting barriers and opportunities to their diffusion. The proposed synoptic might be taken as a point of departure for building a wider analysis on the role of satellite-based solutions to foster a One Health approach
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

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
A wave-particle interaction model for tail ion acceleration in reversed field pinch plasmas
No full textIn the reversed field pinch plasmas produced by the reversed field experiment (RFX), neutral particle measurements reveal the presence in the radial direction of a small population of non-thermal energetic ions (E = 10(3) eV to 8 x 10(3) eV). In this work supra-thermal electrons at the plasma edge are considered to be the free-energy source for the ion acceleration. Fast electrons, moving in the same direction of the main magnetic field, excite an omega similar to omega(pi) electrostatic wave which gives energy to the ions which are accelerated in the direction perpendicular to the local equilibrium magnetic field. The theoretical predictions for the neutral particle fluxes are in agreement with the experimental measurements. Moreover, a correlation between the experimental fast-ion and fast-electron energy densities has been found
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
