Learning nonadjacent dependencies : No need for algebraic-like computations.
2004
Is it possible to learn the relation between 2 nonadjacent events? M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (2002) claimed this to be possible, but only in conditions suggesting the involvement of algebraic-like computations. The present article reports simulation studies and experimental data showing that the observations on which Pena et al. grounded their reasoning were flawed by deep methodological inadequacies. When the invalid data are set aside, the available evidence fits exactly with the predictions of a theory relying on ubiquitous associative mechanisms. Because nonadjacent dependencies are frequent in natural language, this reappraisal has far-reaching implications for t…
RAPPRESENTANZA E DIRITTO EUROPEO
2011
Il lavoro propone una riflessione diretta a cogliere l'influenza che i dati "europei" offrono ad una ricostruzione della rappresentanza. In particolare si parte dalla questione relativa ad una possibile rilevanza del fenomeno rappresentativo nell'ambito dei rapporti c.d. consumeristici, interrogandosi sul se e come vi sia spazio in regole che hanno nella qualità delle parti il loro ambito di riferimento per un fenomeno di sostituzione, qual è la rappresentanza. Viene così analizzato il dibattito interno relativo al concetto di parte, così come emerge nella riflessione sul negozio rappresentativo, per poi esaminare la questione dall'angolo visuale del consumatore, alla luce di quella che app…
Restrictions on data-driven political micro-targeting in Germany
2017
The revitalisation of canvassing in recent elections is strongly related to campaigns´ growing possibilities for analysing voter data to gain knowledge about their constituents, identifying their most likely voters and serving up personalised messages through individual conversations. The research literature about political micro-targeting hardly ever focusses on campaigns in parliamentary democracies with strict data protection laws. Based on in-depth expert interviews we introduce a framework of constraints in strategic political communication and reveal several restrictions on the macro, meso and micro levels which hinder the implementation of sophisticated data strategies in Germany. We…
Responsibility and intellectual property in synthetic biology: A proposal for using Responsible Research and Innovation as a basic framework for inte…
2015
Synthetic biology (SynBio) is an engineering view of biotechnology that has the potential to increase the number and industrial utility of biotechnological applications by implementing engineering principles such as standardization and modularity. The boundaries between SynBio, biotechnology, and metabolic engineering are not always clear, but assessing SynBio in a wider sense—that of modeling‐based biotechnology and/or “sophisticated” metabolic engineering—we find that a significant number of applications and research articles have been generated in the past few years [1]. One of the best‐known examples is that of a synthetic pathway for producing artemisinic acid, a precursor to the antim…
Digital Restitution of Cultural Goods: In Search of a Working Model
2023
AbstractThe paper deals with the problem of digital restitution of art to post-colonial and postdependency countries. A new model of digital restitution composed of two elements: creation of a digital copy with a NFT attached and creation of new property right in a physical and digital object has been proposed. A system of balances between the rights and duties based on the prior user concept has been developed.
The Law of Service Robots
2014
Il settore della robotica attiene alla progettazione e costruzione di un complesso variegato ed eterogeneo di macchine, quali robot, soldati e chirurghi, sistemi automatizzati di trasporto aereo, terrestre e marittimo, applicazioni industriali nell’ambito manifatturiero o nella agricoltura, robotica di servizio e altro ancora. Si tratta di un settore per eccellenza interdisciplinare la varietà di ambiti e applicazioni del quale fa sì che si discuta ancora sulla definizione di robot e su alcune sue proprietà: l’autonomia, l’adattatività o i gradi di interattività. Su queste basi, il problema, attualmente, non è tanto quello di determinare se e in che modo i robot ”agiscano”; la questione ver…
Semi-automatic Quasi-morphological Word Segmentation for Neural Machine Translation
2018
This paper proposes the Prefix-Root-Postfix-Encoding (PRPE) algorithm, which performs close-to-morphological segmentation of words as part of text pre-processing in machine translation. PRPE is a cross-language algorithm requiring only minor tweaking to adapt it for any particular language, a property which makes it potentially useful for morphologically rich languages with no morphological analysers available. As a key part of the proposed algorithm we introduce the ‘Root alignment’ principle to extract potential sub-words from a corpus, as well as a special technique for constructing words from potential sub-words. We conducted experiments with two different neural machine translation sys…
On the stability of the localized single-valued extension property under commuting perturbations
2013
This article concerns the permanence of the single-valued extension property at a point under suitable perturbations. While this property is, in general, not preserved under sums and products of commuting operators, we obtain positive results in the case of commuting perturbations that are quasi-nilpotent, algebraic, or Riesz operators.
An Efficient Traceable Attribute-Based Authentication Scheme with One-Time Attribute Trees
2015
Attribute-based authentication (ABA) is a way to authenticate signers by means of attributes and it requests proof of possessing required attributes from the one to be authenticated. To achieve the property of traceability, required attributes should be combined with the signer’s attribute private keys in order to generate a signature. In some schemes, signers’ attribute keys are related to attribute trees, so changing attribute trees will cause the regeneration of all related attribute keys. In this paper, we propose an efficient traceable ABA scheme, where the generation of signers’ attribute keys is independent from attribute trees. Thus the same set of attribute keys can be used with a …
An Efficient Multi-Show Unlinkable Attribute Based Credential Scheme for a Collaborative E-Health Environment
2017
Modern electronic healthcare (e-health) systems constitute collaborative environments in which patients' private health data are shared across multiple domains. In such environments, patients' privacy can be violated through the linkability of different user access sessions over patient health data. Therefore, enforcing anonymous as well as multi-session unlinkable access for the users in e-health systems is of paramount importance. As a way of achieving this requirement, more emphasis has been given to anonymous attribute credentials, which allows a user to anonymously prove the ownership of a set of attributes to a verifier and thereby gain access to protected resources. Among the existin…
