An End to End Indoor Air Monitoring System Based on Machine Learning and SENSIPLUS Platform
Full text linkIn the framework of indoor air monitoring, this paper proposes an Internet of Things ready solution to detect and classify contaminants. It is based on a compact and low-power integrated system including both sensing and processing capabilities. The sensing is composed of a sensor array on which electrical impedance measurements are performed through a microchip, named SENSIPLUS, while the processing phase is mainly based on Machine Learning techniques, embedded in a low power and low resources micro controller unit, for classification purposes. An extensive experimental campaign on different contaminants has been carried out and raw sensor data have been processed through a lightweight Multi Layer Perceptron for embedded implementation. More complex and computationally costly Deep Learning techniques, as Convolutional Neural Network and Long Short Term Memory, have been adopted as a reference for the validation of Multi Layer Perceptron performance. Results prove good classification capabilities, obtaining an accuracy greater than 75% in average. The obtained results, jointly with the reduced computational costs of the solution, highlight that this proposal is a proof of concept for a pervasive IoT air monitoring system
Culture as a Critical Enabler for Tourism Destination Development
No full textThe relationship between cultural heritage and tourism has stimulated the theoretical debate for many years. While it is evident that cultural attractions have the potential to be critical assets for tourism policymakers and destinations, tourist behaviors are often seen as potential harm to both the preserva- tion of cultural heritage and the development of a profound cultural experience. Nevertheless, a grow- ing number of experiences show that a sound management of cultural tourism can generate substantial social, economic, and even environmental benefits. This chapter aims to investigate the trajectories and strategies tourism destinations can adopt to leverage their (material and immaterial) cultural assets, improve their brand, and eventually, enhance their competitive position in the tourism markets, with particular reference to the case of Parma Italian Capital of Culture 2020

No full textGoing 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
SENSIPLUS: AN INNOVATIVE PLATFORM FOR HEALTH AND SAFETY APPLICATIONS IN SMART CITIES
No full textSmart City is a modern concept, born in the last decade and spreading very quickly all over the world, aiming at improving the citizens’ life quality by largely adopting Information and Communication Technologies (ICT). It is addressed to optimize the government policy and people welfare by means of the analysis of data acquired with pervasive sensors’ networks distributed in indoor and outdoor environments. The Internet of Things (IoT), a new paradigm according to which the everyday life objects are connected to the internet, has a key role in the smart cities development. Such technologies and paradigms are adopted in many applications, as for the air quality monitoring and warranty. The World Health Organization (WHO) states that the Chronic Obstructive Pulmonary Disease (COPD) caused about 3.2 million deaths in 2015 and will be the third one in 2030. For this reason, lots of efforts are devoted to air monitoring and to the development of technologies to reduce the polluting. In this field, the authors are working at the development of an innovative platform, called SENSIPLUSR ,
characterized by sensing, processing and communication capabilities
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
