A possible approach to the development of robotic multi-agent systems
2004
The design of a an agent system for robotics is a problem that involves aspects coming from many different disciplines (robotics, artificial intelligence, computer vision, software engineering). The most difficult part of it, often consists in producing and tuning the algorithms that incorporates the robot behavior (planning, obstacle avoidance,. . . ) and abilities (vision, manipulation, navigation,. . . ). Frequently, the reuse of these parts is left to a copy and paste procedure from previous applications to the new one. In so doing many problems could arise. We propose a comprehensive approach for multi-agent systems oriented to robotics applications that uses a complete design methodol…
A MOBILE ROBOT FOR TRANSPORT APPLICATIONS IN HOSPITAL DOMAIN WITH SAFE HUMAN DETECTION ALGORITHM
2009
We have been developing a MKR (Muratec Keio Robot), an autonomous omni-directional mobile transfer robot system for hospital applications. This robot has a wagon truck to transfer luggage, important specimens and other materials. This study proposes a safe obstacle collision avoidance technique that includes a human detection algorithm for omni directional mobile robots that realizes a safe movement technology. The robot can distinguish people from others obstacles with human detection algorithm. The robot evades to people more safely by considering its relative position and velocity with respect to them. Some experiments in a hospital were carried out to verify the performance of the human…
SOCIETÀ A CONTROLLO PUBBLICO E CONTRATTO DI LAVORO: LA CASSAZIONE TORNA SULLA NULLITÀ VIRTUALE PER ALTERAZIONE DELLA PROCEDURA CONCORSUALE
2021
Il commento analizza la recente e consolidata giurisprudenza di legittimità in materia di rapporto di lavoro alle dipendenze delle società a controllo pubblico: secondo la Corte di Cassazione, che fa leva sui principi generali in tema di nullità contrattuale e di buon andamento e imparzialità dell’agere amministrativo, la nullità della procedura di reclutamento per violazione di norme imperative costituisce causa di nullità virtuale dei contratti di lavoro sottoscritti in esito ad essa, a prescindere dalla circostanza che i lavoratori abbiano dato causa al vizio o ne abbiano avuto consapevolezza. Tale orientamento è stato del resto formalizzato in progresso di tempo dal legislatore con il d…
Il delitto di "caporalato" tra diritti minimi della persona e tutela del mercato del lavoro
2020
Il contributo analizza il reato di intermediazione illecita e sfruttamento lavorativo, offrendo un’analisi comparata con il sistema repressivo tedesco. Lo studio si sofferma, in particolare, sui limiti di legittimazione del diritto penale nella punizione dei fatti di “caporalato”, nel tentativo di scongiurare che l’intervento repressivo nelle dinamiche economiche e contrattuali, di natura sinallagmatica, possa assumere una portata tale da porsi in contrasto con il canone della sussidiarietà. A tal fine, si suggerisce una prospettiva ermeneutica che incentri il disvalore penale del reato di cui all’art. 603-bis c.p. sulla lesione dei diritti fondamentali del lavoratore – riconducibili agli a…
Basic structure and tax havens
2012
In this paper I argue that Rawlsian Law of People (LP) is much more useful to the debate on international distributive justice than it is commonly assumed by many leading political philosophers (Pogge, Nussbaum, Sen, Beitz, Singer). I will show: 1) that these criticisms are misleading, insofar as they do not take the concept of basic structure seriously, and they reduce LP to an instance of ethical statism or of acritical acceptance of cultural pluralism; 2) that the basic domestic structures, and the principles that govern them, depend on the law of peoples and its principles as well. Therefore it is not true that each basic structure is independent of what occurs in the international fiel…
Past and present “Urban voids” as resources for the future. The case-study of Catania
2002
Since the end of the 1960s, the landscapes of major cities have been more and more characterized by the presence of "urban voids". Today these "voids", which are often heterogeneous in their manifestation, dominate the discussions about the transformation and the future of urban areas. The reclaiming and re-use of derelict sites and "cultural heritage" has the duty to assure for the next generation the knowledge of the cultural values of the past. In this paper we will focus our attention on a re-used "cultural heritage": the Multifunctional Centre of Catania (Sicily, Objective 1 region). Thanks to the Urban Programme this "urban void"- abandoned for decades and deteriorated - was recovered…
THE EFFECT OF ALTERNATIVE PREY ON THE DYNAMICS OF IMPERFECT BATESIAN AND MÜLLERIAN MIMICRIES
2004
Both Batesian and Müllerian mimicries are considered classical evidence of natural selection where predation pressure has, at times, created a striking similarity between unrelated prey species. Batesian mimicry, in which palatable mimics resemble unpalatable aposematic species, is parasitic and only beneficial to the mimics. By contrast, in classical Müllerian mimicry the cost of predators' avoidance learning is shared between similar unpalatable co-mimics, and therefore mimicry benefits all parties. Recent studies using mathematical modeling have questioned the dynamics of Müllerian mimicry, suggesting that fitness benefits should be calculated in a way similar to Batesian mimicry; that i…
Il silenzio come pratica di cura nella relazione educativa
2014
In un tempo, come quello in cui agiamo e viviamo, consegnato all’effimero e alla fugacità, il silenzio si riafferma come bisogno formativo e acquista un ruolo di primo piano all’interno del dialogo educativo, come una pratica di cura attraverso cui l’uomo contemporaneo possa contrastare la banalità della chiacchiera e di un’esistenza vissuta in modo inautentico. Se il Novecento pedagogico ha riscoperto il valore educativo del silenzio, oggi tale pratica viene riproposta non solo come atto di tacere, ma anche come apertura di un nuovo orizzonte di senso dentro cui accogliere l’altro, cioè ospitarlo. Vincendo la paura del vuoto, da sempre identificato col nulla, il silenzio non viene più inte…
The relationship between attachment dimensions and perceptions of group relationships over time: An actor–partner interdependence analysis.
2016
A group member’s attachment, anxiety, and avoidance is related to how the group member and the other group members (OGMs) perceive group relationships. In addition, the collective attachment strategies of the OGMs may also be related to how the individual group member and the others perceive the relationships in the group. We extend previous research, using the actor partner interdependence model (APIM), to examine how group members’ and aggregated OGMs’ attachment anxiety and avoid- ance were related to group members’ and OGMs perceptions of positive bonding, positive working, and negative relationships measured early and late in interpersonal growth groups. Three hundred twenty-five Itali…
Reconceptualising resilience within a translational framework is supported by unique and brain-region specific transcriptional signatures in mice
2020
ABSTRACTChronic social defeat (CSD) in mice has been increasingly employed in experimental resilience research. Particularly, the degree of CSD-induced social avoidance is used to classify animals into resilient (socially non-avoidant) versus susceptible (avoidant). In-spired by human data pointing to threat-safety discrimination and responsiveness to extinction training of aversive memories as characteristics of resilient individuals, we here describe a translationally informed stratification which identified three phenotypic subgroups of mice following CSD: the Discriminating-avoiders, characterised by successful social threat-safety discrimination and successful extinction of social avoi…
