    EUDroid: a formal language specifying the behaviour of IoT devices

    No full text
    Recent technologies are offering today many possibilities to end users, which ask for continuous support in a variety of situations. Internet of things (IoTs) and the proliferation of smart devices are offering many opportunities that raise the need to standardise protocols for their interoperability and interaction languages for their management. This study proposes EUDroid, a system composed of a mobile application and an IoT device used as a pill reminder to allow the patients to correctly take their prescribed drugs. A web server stores and manages the therapies that can be defined by the end users. The web server also manages the communication between the app and the device. In order to validate the management of the therapies, a formal language has been proposed. It describes the behaviour of different components of the IoT device, such as LEDs or buzzers, and defines when, with which delay, and for how long time a given event will last, to manage technical concepts related to smart devices for supporting them in following therapies more accurately.Recent technologies are offering today many possibilities to end users, which ask for continuous support in a variety of situations.

    Digital technologies and social networks offer several possibilities for improving the quality of life in Smart Cities. Citizens are willing to contribute to the efficiency of services that Smart Cities offer by reporting through different channels, such as phone/fax, front office, website, mobile app, sensors, several problems they observe in the city. This paper contributes to the advancement of the practice of HCI by describing an experience carried out with the employees of a municipality about the identification and implementation of interactive visualizations, in order to support them in the management of urban issues reported by citizens. The performed experience was inspired by the Cooperative Method Development (CMD), that emphasizes a strong collaboration between IT researchers and experts in a work practice, working side by side and being focused on the practitioners’ problems, in order to identify critical aspects and possible improvements that lead to the design and development of new software artifacts. The municipality employees greatly appreciated their active involvement in the overall CMD process, as well as the improvements on data analysis, thanks to the developed interactive visualizations that enable them to detect trends, anomalies and significant facts in the management of urban issues

    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

    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

    Get PDF
    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

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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

    We 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

    Erysipelotrix rhusiopathiae is the etiologic agent of erysipelas in animals. It is a worldwide diffused disease which affects swine and avian species. Erysipelas in avian is mostly reported in turkey and chicken, although its prevalence is probably underestimated. Even more rarely the disease is reported in wild species, but they could play an important role in disseminating the pathogen. Here we report an unusual focus of erysipelas in a pheasant (Phasianus colchicus) farm. Ten 8-month old birds were brought to our facilities following a history of malaise, sensory impairment and mortality in a pheasant farm. At necropsy, we observed wide alopecic areas, with correspondent thickness of skin. Diffused hemorrhages were evident mainly along the muscles of chest, liver, spleen and epicardium. Catarrhal hemorrhages were also evident in the distal part of gut. Histological observations evidenced necrotic phlogistic foci characterized by fibrotic suppuration from gut and proventricula samples. Thrombotic areas were evident in kidney and spleen samples. In each case, microscopy observations showed bacterial cells and aggregate, also found in the blood. Bacteriological analyses let us isolate and identify E. rhusiopathiae. Following identification, a therapy with -lactamic antimicrobial agents was administered, quick resolving the case. This report confirms the E. rhusiopathiae may circulate in wild birds, such as pheasant. We hypothesize that overcrowding could have promoted the epidemic-like burden of the disease in the farm. Further studies should be carried out to verify the possibility that wild avian species such as pheasant could act as a reservoir for E. rhusiopathia
