Beris-Edward's model with absence of flow
No full textThe article treats the Beris-Edward's Model for liquid crystals with absence of flow. In particular, we consider the case of energy functionals unbounded from below. At the beginning we prove the existence of ground states for the stationary problem set in several open sets and with different boundary conditions. The last part is devoted to the evolution problem in R3, where we establish local and global existence with small initial data. The results come from several applications of Strichartz-type estimates and by contraction arguments

Internet and technology addiction disorders in adolescence
No full textIntroduction: Technology addictions are an important form of behavioral addiction because of their increasing frequency and their impact on the life of adolescents, including their social life, school performance, and intrafamily relationships. We reviewed the scientific literature on dysfunctional uses of technology among adolescents. Our analysis included the psychological features of communication technologies and their patterns of use in adolescence; the psychopathology linked to technological addictions; and general principles of treatment and outcome. Materials and methods: The addictive behaviors are examined within the framework of the changing needs and culture of adolescents, which render them increasingly prone to the dysfunctional or addictive use of technological tools. Discussion and conclusions: The rapid spread of communication and information technologies has a deep impact on the psychological, social, and relational development of adolescents, and in vulnerable individuals it can promote or aggravate dysfunctional behaviors. Mental health professionals, parents, and teachers should become more aware of the addictive power of information communication technologies and the risks related to their uncontrolled use. © 2010 Elsevier Srl.

No full textCombining human intelligence and machine learning for fact-checking: Towards a hybrid human-in-the-loop framework
No full textOnline misinformation is posing a serious threat for the modern society. Assessing the veracity of online information is a complex problem which nowadays is addressed by heavily relying on trained fact-checking experts. This solution is not scalable, and due to the importance of the problem the issue gained the attention of the scientific community, which proposed many based on Artificial Intelligence and Machine Learning methods. Despite the efforts made, the effectiveness of such approaches is not yet enough to allow them to be used without supervision. In this position paper, we propose a hybrid human-in-the-loop framework for fact-checking: we address the misinformation issue by relying on a combination of automatic Artificial Intelligence methods, crowdsourcing ones, and experts. We study the single components of the framework as well as their interactions, and we propose an interleaving of the different components which we believe will serve as a useful starting point for the future research towards effective and scalable fact-checking
