Symmetrical Heyting algebras with a finite order type of operators

The main purpose of this paper is to introduce a class of algebraic structures related to many-valued ukasiewicz algebras. They are symmetrical Heyting algebras with a set of modal operators indexed by a finite completely symmetric poset. A representation theorem is given for these (not functionally complete) algebras.     

Arbitrarily applicable spatial relational responding

Spatial reasoning, where novel spatial relationships are inferred based on trained relationships, can be conceptualized as arbitrarily applicable spatial relational responding. Here, we conducted two experiments to develop and validate, for the first time, a laboratory procedure to establish arbitrarily applicable spatial relational responding in adult humans. In Experiment 1, participants were trained on nonarbitrary spatial relational tasks designed to establish contextual cues for left of, right of, above, and below. Contextual cues were then used to train a series of arbitrary spatial relations involving four abstract shapes. Following training in a subset of arbitrary relations (A is left of B, B is above C, C is right of D), subsequent testing examined the emergence of untrained spatial relations (B is right of A, C is below B, D is left of C, D is below A and A is above D). When absent in initial tests, spatial relational responding was facilitated by a remedial training procedure incorporating nonarbitrary relational guidance. Participants showed patterns of spatial relational responding consistent with test relations. In Experiment 2, a variant reversal design yielded predictable, reversed spatial relational responses. Overall, the present procedures represent the first empirical demonstration of arbitrarily applicable spatial relational responding and thus, arguably, the first functional analytic model of spatial reasoning.     

The Relationship Between Orientations to Happiness and Job Satisfaction One Year Later in a Representative Sample of Employees in Switzerland

There are three different routes to happiness: the pleasant life, the good or engaged life, and the meaningful life. These three orientations are positively related with life satisfaction, but the relation with job satisfaction is still not clear. This study examines the relationship between the three orientations to happiness (OTH) and job satisfaction in a 1-year longitudinal study with a representative sample (N = 752, 387 men) of working adults living in Switzerland. This study is part of a larger survey that includes several self-report measures. Regression analyses showed that engagement was positively related with job satisfaction 1 year later. Moreover, when controlling for sociodemographic variables (i.e., age and gender), work-related variables (i.e., household income, managerial responsibility, and financial responsibility), and the five factors of personality (i.e., neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) the interaction of the three OTH (i.e., pleasure × engagement × meaning), still predicted job satisfaction significantly. Individuals who endorse the three OTH presented the highest job satisfaction 1 year later. Therefore, although engagement is more important for job satisfaction than pleasure or meaning, the best predictor of job satisfaction is the interaction of the three OTH. Thus, people who are high in the three OTH simultaneously enjoy the highest job satisfaction. Future studies should examine whether this relationship is causal.     

Attitude to primary prevention advice of the European Code against cancer in relatives of cancer patients: implications for the development of preventive programmes

Achieving a preventive attitude is the first step in eliminating cancer risk behaviours. This cross-sectional study evaluated the attitude towards the European Code against Cancer, in 3,031 relatives of cancer patients. The study looked for keys to improve attitude by means of educational interventions. Attitude was evaluated using a questionnaire with 63 items and a Likert's scale. Measured from -2 to +2 , the mean score was 0.905 [0.894 - 0.971]. Five per cent had a mean score under 0.38 and another 5% over 1.46. A multivariate analysis found that age, sex and level of education were significantly associated with attitude: young men with a low cultural level were those with the lowest preventive attitude. The family history of cancer was not associated with attitude. Educational interventions should modify the perceived advantages of smoking and drinking, and the disadvantages related to preventive diet and sun and workplace protection.     

Effects of pretraining intrastriatal administration of p-chloroamphetamine on inhibitory avoidance

Pretraining systemic administration of p-chloroamphetamine (PCA) consistently produces retention deficits of inhibitory avoidance. This drug causes a widespread acute release of serotonin from cerebral neuronal terminals, but it is not known where in the brain PCA exerts its disruptive cognitive effects. The present experiment was aimed at determining whether the striatum is a site of action of this drug. PCA (5 microg) was infused, bilaterally, into the striatum of rats at 30, 15, or 5 min before training of inhibitory avoidance, and retention of the task was measured 24 h later. An inversely related time-dependent deficit was found. Together with the results from appropriate control groups, this result strongly suggest that systemic PCA produces its reported cognitive effects, at least in part, through its pharmacological action within the striatum.     

Appreciation of Beauty and Excellence: Relationship with Personality,Prosociality and Well-Being

Appreciation of beauty and excellence (ABE) is one of the least studied character strengths. Therefore, this study aims at advancing the knowledge in this area by (1) developing a scale that measures the three categories of appreciation (i.e., beauty, moral excellence, and non-moral excellence), (2) assessing many of its psychometric properties, and (3) examining the relationship of ABE with personality, prosociality, and well-being. In Study 1, we create and assess an initial set of items measuring ABE. In Study 2, we examine the dimensionality of ABE, and test the internal consistency and validity of the scale. Moreover, we assess the relationships between ABE and personality, prosociality and well-being. In Study 3, we test the temporal stability of the scale. Results revealed that a three-dimensional model of ABE showed the best fit to the data. The scale showed good validity (construct, factorial, incremental) and reliability (internal and temporal). Finally, ABE yielded positive associations with prosociality and well-being, and demonstrated to be more than a linear combination of the Big Five factors of personality.     

Uncertainties

In contemporary science uncertainty is often represented as an intrinsic feature of natural and of human phenomena. As an example we need only think of two important conceptual revolutions that occurred in physics and logic during the first half of the twentieth century: (1) the discovery of Heisenberg’s uncertainty principle in quantum mechanics; (2) the emergence of many-valued logical reasoning, which gave rise to so-called ‘fuzzy thinking’. I discuss the possibility of applying the notions of uncertainty, developed in the framework of quantum mechanics, quantum information and fuzzy logics, to some problems of political and social sciences.     

Classroom justice and psychological engagement: students’ and teachers’ representations

This article presents the results of a study carried out with the aim to: (1) analyze secondary school students’ and their teachers’ ideal representations of classroom justice, (2) deepen the topic of students’ sense of injustice, and (3) explore the links between students’ perceived injustice and their psychological engagement in school, measured on different aspects (identification with one’s own class, learning motivation, dialogue with teachers). A questionnaire was distributed to 400 Italian secondary school students and their 79 teachers. Results show that the representations of ideal classroom justice refer to communication, principle of equality and principles of effort/need, and that the positions of teachers and students on these representations differ. Moreover, students report a rather diffuse and shared feeling of being treated in an unjust manner by their teachers, and this affects their psychological engagement in school. Results are commented on their theoretical, methodological and applicative implications.     

Clinical notes on a case of transvestism in a child

This clinical presentation describes the therapeutic process of a 5-year-old male child presenting as a main symptom quasi-delusional feminine enactments starting at an early age, which persisted for most of his five-year treatment. This symptom was understood in terms of an attempt at restitution, itself the result of being confronted with an autistic structure stemming from a series of traumatic incidents during the oral phase: his mother's pregnancy, abortion, depression and subsequent three-month absence at the end of his first year of life. The clinical material, drawings included, illustrates the interplay of oral, anal and phallic levels, with enactment predominant in sessions. The oral traumatic situation initially led to anal-manic play, then to quasi-delusional female personifications in sessions, later surfacing as an annihilating 'black hole'. All the above issued into a broad enacted phallic-genital unfolding that dramatised an oral-genital primal scene, in the course of which he managed to structure his male identity. Near the end of the analytic process the analysand reworked the 'stages' of the link to the analyst. To end, based on the clinical material, the respective participation of the early and the late Oedipus complex is examined.
