Detecting sensitive information considering privacy is a relevant issue on Online Social Networks (OSNs). It is often difficult for users to manage the privacy associated with their posts on social networks taking into account all the possible consequences. The aim of this work is to provide information about the sensitivity of the content of a publication when a user is going to share it in OSN. For this purpose, we developed a privacy-assistant agent that detects sensitive information. Based on this (...) information, the agent provides a message through a nudge mechanism warning about the possible risks of sharing the message. To avoid being annoying, the agent also considers the user’s previous behaviour (e.g. if he previously ignored certain nudges) and adapts the messages it sends to give more relevance to those categories that are more important to the user from the point of view of the privacy risk. This agent was integrated into the social network Pesedia. We analysed the performance of different models to detect a set of sensitive categories (i.e. location, medical, drug/alcohol, emotion, personal attacks, stereotyping, family and association details, personal details and personally identifiable information) in a dataset of tweets in Spanish. The model that obtained the best results (i.e. F1 and accuracy) and that was finally integrated into the privacy-assistant agent was transformer-based. (shrink)

Negli ultimi anni le ricerche sulla civiltà rupestre del Mezzogiorno medioevale, in seguito agli studi innovativi di Cosimo Damiano Fonseca, hanno condotto alla rivisitazione, attraverso approcci nuovi e con l'ausilio di strumenti sofisticati, di questo fenomeno nelle sue varie sfaccettature. Se, a partire soprattutto dalla fine dell'800, gli studiosi avevano rivolto i loro interessi in specie alle cappelle rupestri e alla loro decorazione pittorica, ovvero all'aspetto, in apparenza il più eclatante, dell'abitato rupestre, di recente l'attenzione si è focalizzata intorno allo (...) studio del paesaggio rupestre stesso e ai suoi valori, inteso come modello insediativo non certamente alternativo, né inferiore, a quello urbano, bensì come elemento specifico all'interno della complessa realtà dell'insediamento umano delle regioni meridionali e della Sicilia tra Tarda Antichità e Medioevo.

El presente trabajo investiga las tesis sobre el poder civil de Alonso de la Veracruz que buscan incorporar en la comunidad política española a los habitantes autóctonos del Nuevo Mundo, tesis que suelen relacionarse con F. de Vitoria y el tomismo español, y que últimamente son consideradas parte del republicanismo novohispano elaborado desde la periferia americana. Se busca demostrar que su propósito era aplicar una teoría de derechos naturales, sin que ello implique participación política de los indios americanos. Se analiza (...) la postura del fraile frente a la diversidad cultural y la guerra contra los indios. The paper explores Alonso de la Veracruz's theses on civil power, which sought to integrate the native inhabitants of the New World into the Spanish political community. These theses, which have usually been associated with F. de Vitoria and Spanish Thomism, have recently come to be considered part of a Novohispanic republicanism developed in the American periphery. The article seeks to show that the purpose of such theses was to apply a theory of natural rights that did not entail the political participation of the indigenous population, as well as to analyze Veracruz's position regarding cultural diversity and the war against the indigenous peoples.

This paper examines key aspects in the innovative behavior of the construction firms that determine their environmental orientation while innovating. Structural equation modeling was used and data of 222 firms retrieved from the Spanish Technological Innovation Panel for 2010 to analyse the drivers of environmental orientation of the construction firms during the innovation process. The results show that the environmental orientation is positively affected by the product and process orientation of construction firms during the innovation process. Furthermore, the positive relation (...) between the importance of market information sources and environmental orientation, mediated by process and product orientation, is discussed. Finally, a model that explains these relations is proposed and validated. Results have important managerial implications for those companies worried about their eco-innovative focus as the types of actions and relations within firms most suitable for improving their eco-innovative orientation are highlighted.

Recensión sobre a obra conxunta de Julia Varela, Pilar Parra e Alejandra Val Cubero.

Trying to overcome Dugundji’s result on uncharacterisability of modal logics by finite logical matrices, Kearns and Ivlev proposed, independently, a characterisation of some modal systems by means of four-valued multivalued truth-functions , as an alternative to Kripke semantics. This constitutes an antecedent of the non-deterministic matrices introduced by Avron and Lev . In this paper we propose a reconstruction of Kearns’s and Ivlev’s results in a uniform way, obtaining an extension to another modal systems. The first part of the paper (...) is devoted to four-valued Nmatrices, including Kearns’s and Ivlev’s. Besides proving with full details Kearns’s results for T, S4 and S5, we also obtain a characterisation of the system B by four-valued Nmatrices with level valuations. Concerning Ivlev’s results, two new modal systems are introduced and char.. (shrink)

ABSTRACT The major approaches to belief revision and non monotonic reasoning proposed in the literature differ along a number of dimensions, including whether they are ?syntax- based? or ?semantic-based?, ?foundational? or ?coherentist?, ?consistence-restoring? or ?inconsistency-tolerant?. Our contribution towards clarifying the connections between these various approaches is threefold: ?We show that the two main approaches to belief revision, the foundations and coherence theories, are mathematically equivalent, thus answering a question left open in [Gar90, Doy92], The distinction between syntax-based approaches to revision (...) and approaches based on (semantic) preferential structures falls along similar lines, and their expressive equivalence is a consequence of this result. ?We formally clarify the connection between belief revision and non monotonic reasoning, in a particularly simple way which also throws light on the connection between consistence- restoring and reasoning-from-inconsistency approaches [BDP95]. ?As a direct application of the above, we show that Poole's (syntax-based) system of default reasoning and Shoham's preferential semantic for non monotonic reasoning are also expressively equivalent, in that they can represent the same set of non monotonic consequence relations.

Laws, codes, and rules are essential for any community, public or private, to operate in an orderly and productive fashion. Without laws and codes, anarchy and chaos abound and the purpose and role of the organization is lost. However, danger is significant, and damage serious and far-reaching when individuals or organizations become so focused on rules, laws, and specifications that basic principles are ignored. This paper discusses the purpose of laws, rules, and codes, to help understand basic principles. With such (...) an understanding an increase in the level of ethical and moral behavior can be obtained without imposing detailed rules. (shrink)

Theoretical discussions of ethics in the broadcasting industry remain abstract, intellectual exercises until they go to court. U.S. v. National Association of Broadcasters (NAB) in 1982, led to the death of the NAB Code of Good Practice. This article examines objections to codes and evidence of need for a revised set of broadcast ethics, visible to a media?conscious public. It calls for adoption of a new ethics code in broadcasting.

This book traces the development of Dialectical Logic within the history of modern western philosophy, culminating in Marx s materialist dialectics. It brings out the essential contours of Logic through a detailed exposition of the ontological and epistem.

In this note, an error in the axiomatization of Ivlev’s modal system Sa+ which we inadvertedly reproduced in our paper “Finite non-deterministic semantics for some modal systems”, is fixed. Additionally, some axioms proposed in were slightly modified. All the technical results in which depend on the previous axiomatization were also fixed. Finally, the discussion about decidability of the level valuation semantics initiated in is taken up. The error in Ivlev’s axiomatization was originally pointed out by H. Omori and D. Skurt (...) in the paper “More modal semantics without possible worlds”, where an alternative solution was proposed. (shrink)

Se estudia la conveniencia de incluir el concepto de histéresis en las disciplinas humanistas, así como la necesidad de incorporar el análisis de los fenómenos donde aquél participa. La histéresis se produce en los más diversos campos de la acción y el pensamiento humanos, y su estudio contribuiría a completar y perfeccionar la visión que tenemos de los mismos. Al realizar la inclusión que aquí se propone, se operan varios cambios de orden epistemológico, operativo y conceptual. En las disciplinas humanistas, (...) los conceptos vienen asumiendo por tradición el papel de herramientas analíticas en bastante mayor medida que el de contenidos sobre los que efectuar el análisis. La histéresis manifiesta su alcance como hecho a analizar y también como herramienta de análisis, pero en el caso presente hemos tenido en cuenta más aspectos del segundo enfoque que del primero. De aquí que nos hayamos centrado en ubicar su campo epistemológico. (shrink)

Las actividades de fomento de la cultura científica se han convertido en una práctica habitual de las instituciones de investigación, que destinan presupuesto y recursos humanos a este objetivo. Cada vez más personal científico y técnico incorpora esta misión a sus tradicionales tareas de investigación y formación. Sin embargo, mientras la investigación y la docencia cuentan con indicadores establecidos, las actividades de divulgación siguen estando consideradas como un ejercicio extraordinario, pocas veces reconocido institucionalmente. En este sentido, el uso de unos (...) indicadores de cultura científica contribuiría a favorecer un cambio de mentalidad y a la obtención de datos objetivos sobre los que orientar las acciones de comunicación social de la ciencia. En este contexto, el Consejo Superior de Investigaciones Científicas (CSIC), a través de su Vicepresidencia Adjunta de Cultura Científica, se ha propuesto analizar las actividades desarrolladas en esta línea, entre 2011 y 2019, en relación a los siguientes indicadores: 1) la inversión económica; 2) el personal dedicado a cultura científica; 3) el número y tipo de actividades; y 4) el público al que se llega. Entre las principales conclusiones, destaca que el CSIC cuenta con una masa crítica más o menos estable de unas 200 personas que se dedican a tareas de cultura científica. Cada año se realizan alrededor de 15.000 actividades (presenciales y no presenciales) en las que se implican alrededor de 3.000 trabajadoras y trabajadores del CSIC. Cada año participan cerca de un millón y medio de personas de manera presencial. (shrink)

The gene regulation function (GRF) provides an operational description of a promoter behavior as a function of the concentration of one of its transcriptional regulators. Behind this apparently trivial definition lies a central concept in biological control: the GRF provides the input/output relationship of each edge in a transcriptional network, independently from the molecular interactions involved. Here we discuss how existing methods allow direct measurement of the GRF, and how several trade‐offs between scalability and accuracy have hindered its application to (...) relatively large networks. We discuss the theoretical and technical requirements for obtaining the GRF. Based on these requirements, we introduce a simplified and easily scalable method that is able to capture the significant parameters of the GRF. The GRF is able to predict the behavior of a simple genetic circuit, illustrating how addressing the quantitative nature of gene regulation substantially increases our comprehension on the mechanisms of gene control.
