Embodiment of intersubjective time: relational dynamics as attractors in the temporal coordination of interpersonal behaviors and experiences
Julien Laroche,Anna Maria Berardi,Eric Brangier
Frontiers in Psychology , 2014, DOI: 10.3389/fpsyg.2014.01180
Abstract: This paper addresses the issue of “being together,” and more specifically the issue of “being together in time.” We provide with an integrative framework that is inspired by phenomenology, the enactive approach and dynamical systems theories. To do so, we first define embodiment as a living and lived phenomenon that emerges from agent-world coupling. We then show that embodiment is essentially dynamical and therefore we describe experiential, behavioral and brain dynamics. Both lived temporality and the temporality of the living appear to be complex, multiscale phenomena. Next we discuss embodied dynamics in the context of interpersonal interactions, and briefly review the empirical literature on between-persons temporal coordination. Overall, we propose that being together in time emerges from the relational dynamics of embodied interactions and their flexible co-regulation.

Thirteen Years of Hyoid Suspension Experience in Multilevel OSAHS Surgery: The Short-Term Results of a Bicentric Study
Pietro Canzi,Anna Berardi,Carmine Tinelli,Filippo Montevecchi,Fabio Pagella,Claudio Vicini,Marco Benazzo
International Journal of Otolaryngology , 2013, DOI: 10.1155/2013/263043
Abstract: Aims. To evaluate thirteen years of hyoid suspension experience in multilevel OSAHS surgery, for which hyoidthyroidpexia represented the exclusive hypopharyngeal approach applied. Materials and Methods. From 1998 to 2011, a bicentric retrospective study was conducted: all adult patients with a diagnosis of OSAHS were enrolled. Specific eligible criteria were established. Pre-/postoperative data concerning ENT and sleep findings were recorded. Recruited subjects were surveilled for a follow-up range from 6 to 18 months. Results. A total of 590 hyoid suspensions were evaluated, but only 140 patients met the specific inclusion criteria. A success rate of 67% was obtained. No intraoperative adverse events or major complications occurred. Excessive daytime sleepiness was observed in 28% of nonresponders. Despite the homogeneous candidate anatomy, ENT awake findings changed differently after surgery. Statistical analysis revealed multilevel surgery to be more effective when AHI < 30. Postoperative AHI was statistically not influenced by preoperative BMI. Conclusions. Hyoid suspension in multilevel treatment is effective when short-term results are considered. The necessity of a more valuable anatomic-based diagnostic approach is crucial to guide the patient selection. Long-term followups and randomized prospective trials with case-control series are needed to increase the level of evidence of this surgery. 1. Introduction Sleep disordered breathing (SDB) surgery has taken its initial steps from the first tracheotomy [1] up to the pioneering applications of robotics in the new millennium [2]. When Sher and colleagues published the unsatisfying results of surgery in patients with hypopharyngeal obstruction, they were probably still not aware that a great number of hypopharyngeal procedures would be developed [3]. Despite the several techniques reported in the literature (e.g., surgical reduction of the tongue base, tongue base stabilization, genioglossus advancement, mortised genioplasty, tongue radiofrequency treatment, hyoepiglottoplasty, and hyoid suspension), many of them should be critically analyzed anyway because they are extremely invasive. The idea of restoring the retrolingual space acting on the hyoid bone was codified by Riley et al. in 1986 [4], but a few years before experimental attempts in animal models had already been demonstrated [5, 6]. Since then, hyoid suspension has been adopted by many authors finally turning into a stepping stone in SDB surgical management [7]. We conducted a bicentric retrospective study to evaluate thirteen years of

Psychiatry Journal , 2013, DOI: 10.1155/2013/548349
Abstract: Objective. To describe the prevalence of patients who screen positive for bipolar disorder (BD) symptoms in primary care comparing two screening instruments: Mood Disorders Questionnaire (MDQ) and Hypomania Checklist (HCL-32). Participants. Adult patients presenting to their primary care practitioners for any cause and reporting current depression symptoms or a depressive episode in the last 6 months. Methods. Subjects completed MDQ and HCL-32, and clinical diagnosis was assessed by a psychiatrist following DSM-IV criteria. Depressive symptoms were evaluated in a subgroup with the Patient Health Questionnaire (PHQ-9). Results. A total of 94 patients were approached to participate and 93 completed the survey. Among these, 8.9% screened positive with MDQ and 43.0% with HCL-32. MDQ positive had more likely features associated with BD: panic disorder and smoking habit ( ). The best test accuracy was performed by cut-off 5 for MDQ (sensitivity = .91; specificity = .67) and 15 for HCL-32 (sensitivity = .64; specificity = .57). Higher total score of PHQ-9 was related to higher total scores at the screening tests ( ). Conclusion. There is a significant prevalence of bipolar symptoms in primary care depressed patients. MDQ seems to have better accuracy and feasibility than HCL-32, features that fit well in the busy setting of primary care. 1. Introduction Bipolar disorder (BD) has an estimated lifetime prevalence rate between 2% and 6% when wider range of bipolar spectrum disorders is considered [1]. It is a complex mood disorder frequently associated with medical and psychiatric comorbidity and high suicide rate [2]. Suicidal risk in BD is esteemed to be 15–20 times higher than the general population, and self-harm ideation is reported by 79% of patients [3, 4]. Nevertheless, an average delay of 8–10 years from first onset of mood symptoms to a formal diagnosis of bipolar disorder occurs [5, 6]. Longitudinal researches show that a patient is euthymic for half of the time, while manic or hypomanic symptoms are present only in the 12%; in the rest of the time, a patient has depressive symptoms [7, 8]. Hypomanic symptoms are often perceived as egosyntonic, while it is depression that usually leads the patient to the physician [9]. Thus, any loss or lack of information on hypomanic symptoms increases the bias in favour of a diagnosis of depression [10]. Primary care is the health service entry point for the majority of people suffering from depressive disorders and therefore could play a key role in the detection and management of BD. Although prevalence of
HUMBOLDT:: il progetto EU per l'interoperabilità delle informazioni geo-spaziali
Laura Berardi
GEOmedia , 2012,
Abstract: L'interoperabilità si è oramai qualificata come il focus dello sviluppo delle GI per il vicino futuro. Risorse economiche, iniziative politiche, dati e soluzioni tecniche sono oggi protese a creare un ambiente collaborativo per rendere i dati quanto più interoperabili possibile e tramite essi ed i servizi associati a fornire sistemi di monitoraggio, controllo e decisione più efficaci ed efficienti. In EUROPA la direttiva INSPIRE è punto di riferimento ma non è il solo occorre infatti ricordare che altre iniziative e programmi quali GMES e successivamente SEIS offrono il necessario supporto alla interoperabilità facendone il proprio focus. Per questo in questo numero ho ritenuto di ospitare un articolo tematico scritto da Laura Berardi circa il progetto HUMBOLDT che , iniziato sotto l'egida di GMES, ha visto la sua conclusione di recente producendo un consistente corpus di software e di metodi per la interoperabilità della GI. HUMBOLDT: the EU project for interoperability of geo-spatial information By the INSPIRE Directive transposition, the geospatial data harmonization need is now established, and the National Public Ad-ministrations are addressing the problem.The HUMBOLDT European project pro-vides some answers as method and tools to be implemented. A project overview is shown below in relation to what is address-ing at this time in Europe.

Abstract: In this paper we prove that a total n-spread of PG(2n+1,q) gives us a new 3-design. Moreover, in the case n=1 we construct some new 2-design using spreads.
Adolescenti e contesto contemporaneo
Elisabetta Berardi
Narrare i Gruppi , 2013,
Abstract: Riassunto Il seguente lavoro cerca di comprendere le ragioni e le implicazioni relazionali, sociali e culturali del rapporto che i giovani intrattengono con gli adulti, in particolar modo nella forma del domandare (aiuto o spiegazioni) e del ricercare il senso delle cose attraverso il pensare le cose stesse. Il lavoro si sviluppa a partire da una riflessione sulle relazioni che si possono osservare, a livello fenomenologico, nell’ambito scolastico in relazione a possibili prospettive di cambiamento.Parole chiave: adolescenza, scuola, limite Teens and contemporary contextAbstract The following paper seeks to understand the relational, social and cultural reasons and implications of the relationship young people have with adults, especially in the form of asking (for help or explanations) and looking for the meaning of things through thinking about things themselves. The work develops from a reflection on the relationships that can be observed at the phenomenological level, in schools in relation to possible perspectives of change. Key word: adolescence, school, limit.
Rosenbrock-type methods applied to discontinuous differential systems
Marco Berardi
Mathematics , 2012,
Abstract: In this paper we will study the numerical solution of a discontinuous differential system by a Rosenbrock method. We will also focus on one-sided approach in the context of Rosenbrock schemes, and we will suggest a technique based on the use of continuous extension, in order to locate the event point, with an application to discontinuous singularly perturbed systems.
An intuitionistic version of Ramsey Theorem (italian version)
Stefano Berardi
Computer Science , 2014,
Abstract: Ramsey Theorem [6] for pairs is intuitionistically but not classically provable: it is equivalent to a subclassical principle [2]. In this note we show that Ramsey may be restated in an intuitionistically provable form, which is informative (or at least without negations), and classically equivalent to the original. With respect to previous works of the same kind, we do not use no counterexample as in [1], [5], nor we add a new principle to the intuitionism as in [4]. We claim that this intuitionistic version of Ramsey could be use to replace Ramsey Theorem in the convergence proof of programs included in [3]. [1] Gianluigi Bellin.

L'autoapprendimento multimediale del russo per principianti: Kraski
Liudmila Buglakova,Simona Berardi
Studi Slavistici , 2004,
Abstract: Multimedia self-study of the Russian language at beginners' level: Kraski Kraski was developed at the Interfaculty Language Centre of Forlì (University of Bologna) and is intended for use for self-study of the Russian language in an academic context. The Interfaculty Language Centre in Forlì decided not to use a ready-made software for the realization of this project but, instead, designed software which takes into account not only the language-learning aims but also the needs of the user. Kraski is divided into four topic units which become increasingly more difficult as regards linguistic ability and communicative competence. Each unit presents three situations through the use of a video clip, each of these is followed by six exercises designed to consolidate vocabulary and morphological knowledge. In most of the exercises, the user is helped by the use of the grammar cards: as the course is designed to improve communicative competence, the grammar explanations are given solely as an aid to the learner within the context of the course and are presented schematically. If an exercise includes unknown vocabulary then a hypertext link allows the user to consult a multimedia vocabulary card which includes images and sounds. At the end of every topic unit, we find the section Talking about . which contains different speaking activities which act as a sort of self-evaluation of the progress made and help to improve communicative ability. The self-study user is also helped by the presence of several aids which can be consulted at any time: Cyrillic Alphabet, The Sounds, Grammar Cards, Vocabulary Cards, Dictionary.
