Vladimir Soloviev et Jacques Maritain sont des philosophes pour aujourd'hui et pour demain. Ils ont laissé des œuvres considérables par leur originalité, leur profondeur et la qualité de leur style. Célèbres, puis un peu oubliés, ces deux talentueux penseurs ont cherché la vérité. Ni Soloviev ni Maritain n'ont eu d'ailleurs des carrières académiques classiques, et la liberté que donne une vie dispensée d'obligations administratives a probablement favorisé leur remarquable créativité. L'un et l'autre ont aimé non seulement le Christ, mais aussi (...) son Eglise tout en ayant des appartenances confessionnelles différentes. "L'ouvrage que l'on présente ici est le fruit de deux colloques tenus successivement à Moscou et à Kiev en 2006. Il s'agissait de faire mieux connaître Soloviev en Occident et Maritain en Russie ou en Ukraine. C'est une manière de dialogue entre deux inspirations que l'on pourrait rattacher à Platon dans le cas de Soloviev et à Aristote avec Maritain, mais aussi et surtout à un personnalisme chrétien qui les caractérise.".

This modern, advanced textbook reviews modal logic, a field which caught the attention of computer scientists in the late 1970's.

Combining logics has become a rapidly expanding enterprise that is inspired mainly by concerns about modularity and the wish to join together tailor made logical tools into more powerful but still manageable ones. A natural question is whether it offers anything new over and above existing standard languages. By analysing a number of applications where combined logics arise, we argue that combined logics are a potentially valuable tool in applied logic, and that endorsements of standard languages often miss the point. (...) Using the history of quantified modal logic as our main example, we also show that the use of combined structures and logics is a recurring theme in the analysis of existing logical systems.

This is an exploratory paper about combining logics, combining theories and combining structures. Typically when one applies logic to such areas as computer science, artificial intelligence or linguistics, one encounters hybrid ontologies. The aim of this paper is to identify plausible strategies for coping with ontological richness.

Typically when one applies logic to such areas as computer science, artificial intelligence or linguistics, one encounters hybrid ontologies. The aim of this paper is to identify plausible strategies for coping with ontological richness.

The idea of combining logics, structures, and theories has recently been attracting interest in areas as diverse as constraint logic programming, theorem proving, verification, computational linguistics, artificial intelligence and indeed, various branches of logic itself. It would be an exaggeration to claim that these (scattered, and by-and-large independent) investigations have crystallized into an enterprise meriting the title "combined methods"; nonetheless, a number of interesting themes are emerging. This introduction notes some prominent ones and relates them to the papers in this (...) special issue. (shrink)

This paper investigates the relationship between two outcomes of relationship marketing – affective commitment and behavioral loyalty – and consumers' unethical behavior. The main objective of the study is to assess whether affective commitment and behavioral loyalty to a store translate into more ethical behavior towards that store, controlling for the variables of age, gender, and ethical beliefs. The study does not rely on a single measurement tool, but is based on ten months' panel data and three different mail surveys (...) targeted at 359 Belgian households. The results provide support for our hypothesis that affective commitment is indeed negatively correlated with consumers' unethical behavior. The same conclusion could not be drawn for the relationship between behavioral loyalty and consumers' unethical behavior. No significant relationship was detected, not even in situations where affective commitment was high. The results hold major implications for retailing practice. (shrink)

This paper presents an analysis of face emoji (disc-shaped pictograms with stylized facial expressions) that accompany written text. We propose that there is a use of face emoji in which they comment on a target proposition expressed by the accompanying text, as opposed to making an independent contribution to discourse. Focusing on positively valenced and negatively valenced emoji (which we gloss as _happy_ and _unhappy_, respectively), we argue that the emoji comment on how the target proposition bears on a contextually (...) provided discourse value endorsed by the author. Discourse values embody what an author desires, aspires to, wishes for, or hopes for. Our analysis derives a range of non-trivial generalizations, including (i) ordering restrictions with regards to the placement of emoji and text, (ii) cases of apparent mixed emotions, and (iii) cases where the lexical content of the accompanying text influences the acceptability of a face emoji.

The present study investigates the influence of self-regulatory focus on consumer ethical beliefs (i.e., consumers' judgment of various unethical consumer practices). The self-regulatory focus framework is highly influential and applies to an impressively wide spectrum of topics across a diverse array of domains. However, previous research has not yet examined the link between this personality construct and the consumer ethics field. Findings indicate that promotion affects one's attitude toward questionable consumer practices with those having a stronger (versus weaker) promotion focus (...) being more likely to believe these consumer misbehaviors to be acceptable. Further, this study shows that prevention influences one's perception of morally dubious consumer practices with those having a stronger (versus weaker) prevention focus being more inclined to believe these questionable consumer activities to be unacceptable.

Healey et al. introduce the special issue with a brief overview of work on communication in the Cognitive Sciences and some of the historical and conceptual influences that have marginalized the study of miscommunication. Drawing on more recent work in Cognitive Science and Conversation Analysis they argue that miscommunication is in fact a highly structured, ubiquitous phenomenon that is fundamental to human interaction.

This paper is about a special version of PDL, proposed by Marcus Kracht, for reasoning about sibling ordered trees. It has four basic programs corresponding to the child, parent, left- and right-sibling relations in such trees. The original motivation for this language is rooted in the field of model-theoretic syntax. Motivated by recent developments in the area of semi-structured data, and, especially, in the field of query languages for XML (eXtensible Markup Language) documents, we revisit the language. This renewed interest (...) comes with a special focus on complexity and expressivity aspects of the language, aspects that have so far largely been ignored. We survey and derive complexity results, and spend most of the paper on the most important open question concerning the language: what is its expressive power? We approach this question from two angles: Which first-order properties can be expressed? And which second-order properties? While we are still some way from definitive answers to these questions, we discuss two first-order fragments of the PDL language for ordered trees, and show how the language can be used to express some typical (second-order) problems, like the boolean circuit and the frontier problem.

In this paper back-and-forth structures are applied to the semantics of natural language. Back-and-forth structures consist of an event structure and an interval structure communicating via a relational link; transitions in the one structure correspond to transitions in the other. Such entities enable us to view temporal constructions (such as tense, aspect, and temporal connectives) as methods of moving systematically between information sources. We illustrate this with a treatment of the English present perfect, and progressive aspect, that draws on ideas (...) developed in Moens & Steedman (1988), and discuss the role of rich ontologies in formal semantics.

This paper focuses on segmenting digital movie and TV series pirates and on investigating the effectiveness of piracy-combatting measures i.e., legal and educational strategies, in light of these segments. To address these research objectives, two online studies were conducted. First, 1277 valid responses were gathered with an online survey. Four pirate segments were found based on differing combinations of attitude toward piracy, ethical evaluation of piracy and feelings of guilt. The anti-pirate, conflicted pirate, cavalier pirate, and die-hard pirate can be (...) placed on a continuum of increasing pirating frequency, subjective norm, pirating self-efficacy, habit, and decreasing in perceived harm, respectively. The segments also differ in deontological and teleological orientations. Second, in an experimental mixed design, we find that the educational strategy is more effective than the legal strategy in lowering pirating intentions for the conflicted and cavalier pirate. However, both strategies fail at lowering intentions of the die-hard pirate, although perceived harm and perceived impunity were significantly influenced. These findings offer a more profound understanding of pirate segments and how they react differently to piracy-combatting measures. As a result, better strategies can be developed to control digital piracy. (shrink)

Previous studies show evidence of double standards in terms of individuals being more tolerant of questionable consumer practices than of similar business practices. However, whether these double standards are necessarily due to the fact that one party is a business company while the other is a consumer was not addressed. The results of our two experimental studies, conducted among 277 (Study 1) and 264 (Study 2) participants from a Western European country by means of an anonymous self-administered online survey, demonstrate (...) that the respondents were not only harsher in their judgments of unethical business (vs. consumer) behavior, but also harsher in their judgments of unethical behavior by prosperous (vs. non-prosperous) consumers and prosperous (vs. non-prosperous) business companies (Study 1). Further, they were also less tolerant of unethical behavior by consumers (vs. one's best friend) and business companies with which they have a less than good (vs. a good) relationship (Study 2). These results indicate that double standards are due to differences in perceived wealth between subjects and in the individual's relationship with subjects. These two factors imply that double standards are not strictly reserved to consumer-business relations, but might also be used in business-business and consumer-consumer relations. Further, these results indicate that companies need to be aware of the fact that good financial figures may backfire as they might lead individuals to be more critical of a company's deceptive practices. Moreover, these findings point to the importance of businesses investing resources-and to keep investing resources-in developing a good relationship with stakeholders as these good relationships lead to stakeholders being less prone to make moral condemnations.

BackgroundAlthough the number of reporting guidelines has grown rapidly, few have gone through an updating process. The STARD statement (Standards for Reporting Diagnostic Accuracy), published in 2003 to help improve the transparency and completeness of reporting of diagnostic accuracy studies, was recently updated in a systematic way. Here, we describe the steps taken and a justification for the changes made.ResultsA 4-member Project Team coordinated the updating process; a 14-member Steering Committee was regularly solicited by the Project Team when making critical (...) decisions. First, a review of the literature was performed to identify topics and items potentially relevant to the STARD updating process. After this, the 85 members of the STARD Group were invited to participate in two online surveys to identify items that needed to be modified, removed from, or added to the STARD checklist. Based on the results of the literature review process, 33 items were presented to the STARD Group in the online survey: 25 original items and 8 new items; 73 STARD Group members (86 %) completed the first survey, and 79 STARD Group members (93 %) completed the second survey.Then, an in-person consensus meeting was organized among the members of the Project Team and Steering Committee to develop a consensual draft version of STARD 2015. This version was piloted in three rounds among a total of 32 expert and non-expert users. Piloting mostly led to rewording of items. After this, the update was finalized. The updated STARD 2015 list now consists of 30 items. Compared to the previous version of STARD, three original items were each converted into two new items, four original items were incorporated into other items, and seven new items were added.ConclusionsAfter a systematic updating process, STARD 2015 provides an updated list of 30 essential items for reporting diagnostic accuracy studies.

El artículo estudia la teoría de la guerra justa, en san Agustín, considerándolo como el fundador de esta teoría, ya que fue el primero en articular los criterios perennes dentro del marco de "ethos" cristiano del amor e igualdad como seres humanos creados a imagen y semejanza del Creador. Trata también del influjo de Agustín en el desarrollo de esta teoría de la guerra justa.

In this paper we analyze the existence of joint probabilities for the Bell-type and GHZ entangled states. We then propose the usage of nonmonotonic upper probabilities as a tool to derive consistent joint upper probabilities for the contextual hidden variables. Finally, we show that for the extreme example of no error, the GHZ state allows for the definition of a joint upper probability that is consistent with the strong correlations.

In a sample of 615 Belgians a model for fair trade buying behaviour was developed. The impact of fair trade knowledge, general attitudes towards fair trade, attitudes towards fair trade products, and the perception of the quality and quantity of fair trade information on the reported amount of money spent on fair trade products were assessed. Fair trade knowledge, overall concern and scepticism towards fair trade, and the perception of the perceived quantity and quality of fair trade information, influence buying (...) behaviour directly and indirectly through product attitudes. Interest in fair trade products, price acceptability and product liking have a significant impact on fair trade buying behaviour. Product interest is the most important variable influencing buying behaviour. Implications for the campaigns of governments and for the marketing strategy of fair trade organisations are offered.

For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, (...) a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.
