Le disposizioni rimesse all'arbitrio di un terzo

Princ\uecpi di fondo della materia testamentaria sono la personalit\ue0 del negozio di ultima volont\ue0 e la determinabilit\ue0 delle disposizioni testamentarie, il primo imponendo che le disposizioni liberali provengano dal testatore, il secondo ammettendo il rinvio ad una fonte esterna. Le disposizioni che rimettano alla volont\ue0 del terzo la determinazione del legato o del legatario non sono ammissibili senza limiti, richiedendosi, di converso, che il testatore circoscriva la facolt\ue0 di scelta del terzo, o che questi effettui la scelta sulla base del suo prudente arbitrio. \uc8 vietato, quindi, il rinvio al mero arbitrio del terzo, in quanto incompatibile con la personalit\ue0 del negozio di ultima volont\ue0. Il divieto dell\u2019istituzione di erede, che non pu\uf2 essere rimessa al terzo, neppure entro soggetti determinati dal testatore, si giustifica in considerazione del carattere personalissimo e delle attribuzioni di ordine non patrimoniale connesse al titolo di erede. Pare opportuna l\u2019adozione di un criterio uniforme, per la determinazione sia dell\u2019oggetto sia del beneficiario del legato, da parte di un terzo, idoneo ad un\u2019effettiva e non soltanto formale salvaguardia del principio della personalit\ue0, nonch\ue9 l\u2019espressa previsione della facolt\ue0 di ricorso al giudice, nel caso di mancata determinazione dell\u2019oggetto del legato, o di scelta iniqua, da parte del terzo

Inductive Logic Programming as Abductive Search

We present a novel approach to non-monotonic ILP and its implementation called TAL (Top-directed Abductive Learning). TAL overcomes some of the completeness problems of ILP systems based on Inverse Entailment and is the first top-down ILP system that allows background theories and hypotheses to be normal logic programs. The approach relies on mapping an ILP problem into an equivalent ALP one. This enables the use of established ALP proof procedures and the specification of richer language bias with integrity constraints. The mapping provides a principled search space for an ILP problem, over which an abductive search is used to compute inductive solutions

Collaborative Privacy Policy Authoring in a Social Networking Context.

Recent years have seen a significant increase in the popularity of social networking services. These online services enable users to construct groups of contacts, referred to as friends, with which they can share digital content and communicate. This sharing is actively encouraged by the social networking services, with users privacy often seen as a secondary concern. In this paper we first propose a privacy-aware social networking service and then introduce a collaborative approach to authoring privacy policies for the service. In addressing user privacy, our approach takes into account the needs of all parties affected by the disclosure of information and digital content. © 2010 Crown

La adicción a la nicotina: vulnerabilidad, epigénesis y modelos animales de estudio

This article is a summary about the current research of nicotine effects on the nervous system and its relationship to the generation of an addictive behavior. Like other drugs of abuse, nicotine activates the reward pathway, which in turn is involved in certain psychiatric diseases. There are individuals who have a high vulnerability to nicotine addiction. This may be due to genetic and epigenetic factors and/or the environment. In this review, we described some epigenetic factors that may be involved in those phenomena. The two animal models most widely used for studying the reinforcing effects of nicotine are: self-administration and conditioning place preference (CPP). Here, we emphasized the CPP, due to its potential application in humans. In addition, we described the locomotor activity model (as a measure of psychostimulant effects) to study vulnerability to drugs of abuse.Este artículo es un resumen de las investigaciones actuales sobre los efectos de la nicotina en el sistema nervioso y su relación con la generación de una conducta adictiva. Al igual que otros psicoestimulantes, la nicotina activa la vía de la recompensa, la que también está involucrada en ciertas enfermedades psiquiátricas. Existen individuos que presentan una alta vulnerabilidad a volverse adictos a la nicotina. Esto puede deberse a factores tanto genéticos como epigenéticos y/o al entorno. En este trabajo se describen algunos factores epigenéticos implicados en estos fenómenos. Para este tipo de estudios, existen dos modelos comportamentales en animales: la autoadministración y el condicionamiento al lugar (CPP). Aquí, el CPP se explica en detalle por su potencial aplicación en humanos. Además, se describe la determinación comportamental de la actividad locomotora (lo cual indica el efecto causado por un psicoestimulante) como modelo para estudiar la vulnerabilidad individual a las drogas.Fil: Pastor, Verónica.

Privacy Butler: A personal privacy rights manager for online presence.

The online presence projected by a person is comprised of all the information about them available on the Internet. In online communities and social networking services, it is often possible for third-parties to modify this content by, for example, commenting on existing content or uploading new content. This has the potential to negatively impact the privacy of a presence owner (the person referred to by the on-line content) by disclosing information about them without consent. In this paper we propose a Privacy Butler, an automated service that can monitor a persons online presence and attempt to make corrections based on policies specified by the owner of the online presence. © 2010 IEEE.Accepted versio

Intra-datacenter links exploiting PCI express generation 4 interconnections

We demonstrate few-km reaches for PCIe-based optical fiber interconnections according to latency limitations, characterizing 16-Gb/s per lane Generation4 up to 10 km and confirming the Generation3 compliance of 2-km links employing suitable PCIe cards
