Recognizing social relationships from an egocentric vision perspective
No full textIn this chapter we address the problem of partitioning social gatherings into interacting groups in egocentric scenarios. People in the scene are tracked, and their head pose and 3D location are estimated. Following the formalism of the f-formation, we define as regards the orientation and distance inherently social pairwise features capable of describing how two people stand in relation to one another. We present a structural SVM-based approach to learn how to weight each component of the feature vector depending on the social situation being applied to. To better understand the social dynamics, we also estimate what we call the social relevance of each subject in a group using a saliency attentive model. Extensive tests on two publicly available datasets show that our solution achieves encouraging results when detecting social groups and their relevant subjects in challenging egocentric scenarios

No full textAn IoT-based Smart Museum for a new interactive cultural experience
No full textArt and culture have always played an important role in human beings lives. Over the centuries, hundred of museums and art galleries have preserved our diverse cultural heritage and served as important sources of education and learning. Museums are nowadays a tool of entertainment such as theatres or cinemas. Today, museums and art galleries usually provide visitors either with paper booklets or with audio guides. Visits at museums are often considered boring, because it is hard for museums curators to catch the attention of tourists. In particular, it is difficult to define in advance a tour for all the visitors, because interests may vary from person to person. Interests are different from children to adults, students group from single visitor, casual visitor to fond-visitor. Interactive and personalized museum tours need to be developed. In this perspective, a significant contribution can be given by the next Internet of Things (IoT), which involves the extension of the Internet to small and low-cost “things” that are thought to realize smart environments in order to provide new services to the users. IoT aims to create a better world for people, where smart objects around us know what we like, what we want and act accordingly without explicit gestures [1]. Taking into account all these considerations, we have developed a system able to address all the above- described issues. This work is partially supported by the research project “PON04a2_D - DICET LivingLab Di Cultura e Tecnologia – INMOTO – OR.C.HE.S.T.R.A.”, funded by the Italian Ministry of Education, University and Research (MIUR). More in detail, the solution developed enables wearable devices, interacting with an IoT- based smart environment, to act as museum guides, providing a real interactive cultural experience
A location-aware architecture for an IoT-based smart museum
No full textThe Internet of Things, whose main goal is to automatically predict users' desires, can find very interesting opportunities in the art and culture field, as the tourism is one of the main driving engines of the modern society. Currently, the innovation process in this field is growing at a slower pace, so the cultural heritage is a prerogative of a restricted category of users. To address this issue, a significant technological improvement is necessary in the culture-dedicated locations, which do not usually allow the installation of hardware infrastructures. In this paper, we design and validate a no-invasive indoor location-aware architecture able to enhance the user experience in a museum. The system relies on the user's smartphone and a wearable device (with image recognition and localization capabilities) to automatically deliver personalized cultural contents related to the observed artworks. The proposal was validated in the MUST museum in Lecce (Italy)

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
