Decidability by filtrations for graded normal logics (graded modalities V)

We prove decidability for all of the main graded normal logics, by a notion of filtration suitably conceived for this environment.Presented byJan Zygmunt     

On the relation provable equivalence and on partitions in effectively inseparable sets

We generalize a well-knownSmullyan's result, by showing that any two sets of the kindC _a = {x/ xa} andC _b = {x/ xb} are effectively inseparable (if I b). Then we investigate logical and recursive consequences of this fact (see Introduction).     

Understanding the Complexity of Human Aggression: Affective,Cognitive, and Social Dimensions of Individual Differences in Propensity Toward Aggression

Human aggression is a complex phenomenon operating at multiple levels. Converging evidence distinguishes ‘hot’ aggression, impulsive and emotionally-centered, from ‘cool’ aggression, cognitively based and instrumental. The correspondence of these aggressive response patterns with individual differences in Propensity toward Aggression was investigated. Our data (from 477 Italian adults) map ten of these aggression indicators into the personality space defined by the Five-Factor Model (FFM) of personality. The quadrant containing most of these variables is defined by Emotional Instability (the negative pole of Emotional Stability) and Hostility (the negative pole of Friendliness). Factor analysis uncovered two factors that accounted for nearly 60 percent of the variance in Propensity toward Aggression: Emotional Responsivity and Positive Evaluation of Violence. Practical implications for issues of health and disease, violence, and interventions for different forms of adults' and children's aggression are outlined.     

Priority monism,dependence and fundamentality

Philosophical Studies - Priority monism (PM) is roughly the view that the universe is the only fundamental object, that is, a concrete object that does not depend on any other concrete object....     

Neighborhood effects in reading aloud: new findings and new challenges for computational models

A word from a dense neighborhood is often read aloud faster than a word from a sparse neighborhood. This advantage is usually attributed to orthography, but orthographic and phonological neighbors are typically confounded. Two experiments investigated the effect of neighborhood density on reading aloud when phonological density was varied while orthographic density was held constant, and vice versa. A phonological neighborhood effect was observed, but not an orthographic one. These results are inconsistent with the predominant role ascribed to orthographic neighbors in accounts of visual word recognition and reading aloud. Consistent with this interpretation, 6 different computational models of reading aloud failed to simulate this pattern of results. The results of the present experiments thus provide a new understanding of some of the processes underlying reading aloud, and new challenges for computational models.     

Verb-noun double dissociation in aphasic lexical impairments: the role of word frequency and imageability

Neurolinguistic studies have provided important evidence regarding the organization of lexical representations and the structure of underlying conceptual knowledge; in particular, it has been shown that the retrieval of verbs and nouns can be damaged selectively. Dissociated lexical damage is proof of an independent mental organization of lexical representations and/or of the underlying processes. The aim of the present study is to estimate the rate of dissociated impairments for nouns and verbs on a large sample of mild to moderate aphasic patients and to investigate the mechanisms underlying such phenomena. In addition, the authors wished to verify to what degree the impairment for nouns and verbs is related to a specific type of language disorder. A confrontation naming task for verbs and nouns was administered to 58 aphasic patients. The major lexical (word frequency and age of acquisition) and semantic variables (familiarity and imageability of the underlying concept) were considered for each noun and verb used in the task. Verbs were distinguished by major functional classes (transitive, intransitive, and ergative verbs). The data collected from this task were analyzed twice: (i) as a group study comparison of major aphasic subgroups and (ii) as a multiple single case study to evaluate the differences on the naming of verbs and nouns and the effect of the lexical semantic variables on each individual patient. The results confirm the existence of dissociated naming impairments of verbs and nouns. Selective impairment of verbs is more frequent (34%) than that of nouns (10%). In many cases, the dissociated pattern of naming impairment disappeared when the effect of the concomitant variables (word frequency and imageability) was removed, but in approximately one-fifth of the cases the noun or verb superiority was preserved. Noun superiority emerged in five of six agrammatic patients. Both the naming of verbs (n = 9) or of nouns (n = 6) could be impaired selectively in fluent aphasic patients. The results lend support to the hypothesis of an independent mental organization of nouns and verbs, but a substantial effect of imageability and word frequency suggests an interaction of the naming impairment with underlying lexical and semantic aspects.     

Facing guilt: Role of negative affectivity,need for reparation,and fear of punishment in leading to prosocial behaviour and aggression

The present study aims to further corroborate and to extend the scope of previous findings regarding the path of influence between negative affectivity, need for reparation and fear of punishment when examining the determinants and the motivational components of guilt. Data were collected from three different European countries (i.e. Italy, Hungary, and the Czech Republic). About 1100 young adolescents were involved in the research. The generalizability of a nomological network linking individual differences in Negative Affectivity to Need for Reparation, Fear of Punishment, Prosocial Behaviour, and Aggression has been investigated across countries and gender, by means of structural equation modelling. Need for Reparation turns out to be positively related to Prosocial Behaviour and negatively related to Aggression. Fear for Punishment turns out to be positively related to Aggression and negatively related to Prosocial Behaviour, with the exception of Hungary. Alternative paths of influence among considered variables have been examined. Practical implications for prevention and education are underlined. Copyright © 2001 John Wiley & Sons, Ltd.     

When Likeness Goes with Liking: The Case of Political Preference

Three studies show that people tend to vote for politicians (i.e., either Romano Prodi or Silvio Berlusconi in Italy or George W. Bush or John Kerry in the United States) whose traits they rate as being most similar to their own. People perceived higher similarity between themselves and political figures with respect to traits that were most distinctive of each platform and their respective leaders. These findings, while corroborating the similarity-attraction relationship, further attest to the role that personal characteristics of both voters and candidates play in orienting political preference.     

Travailleurs Étrangers sur le Marché du Travail Suisse: Quels Modes D’incorporation?

This article deals with the opportunities foreign workers have to participate in the job market on an equal footing in the state in which they reside. Using Switzerland as an example, we will pay particular attention to the possibility or not for qualified foreign workers to transfer their cultural capital (Bourdieu, La distinction. Critique sociale du jugement, Paris: Minuit, 1979) from their home to their new country, in other words to perform a job matching their level of training and which enables them to emphasize the professional qualification obtained in the past.
