We prove that there are two involutions defined by monadic terms that characterize Monadic Algebras. We further prove that the variety of Monadic Algebras is the smallest variety of Interior Algebras where these involutions give rise to an interpretation from the variety of Bounded Distributive Lattices into it.Research funded by Fondecyt, project N 764-1987. 相似文献

We obtain in this paper a representation of the formulae of extensions ofL
by generalized quantifiers through functors between categories of first-order structures and partial isomorphisms. The main tool in the proofs is the back-and-forth technique. As a corollary we obtain the Caicedo's version of Fraïssés theorem characterizing elementary equivalence for such languages. We also discuss informally some geometrical interpretations of our results. 相似文献

The purpose of this study was to clarify the role of team resilience on different facets of effectiveness (team viability and quality of the group experience). Moreover, given the importance of team resilience for the organizational context, it was also our aim to contribute to the study of the conditions that promote team resilience, analyzing the role of transformational leadership. Finally, we examined whether the relationship between transformational leadership and team resilience stimulates positive team outcomes. Ninety teams (445 employees from 40 companies) were surveyed and path analysis was used in the test of the hypotheses. The results showed a positive direct effect of team resilience on both team viability and the quality of the group experience. Moreover, a positive relationship was also identified between transformational leadership and team resilience. Finally, support was found for the mediated effect of team resilience on the relationship between transformational leadership and the dimensions of team effectiveness considered. The findings of this study highlight the role of team resilience as an intervening process between transformational leadership and team effectiveness. Supervisors should promote team resilience, adopting transformational leadership behaviors, in order to contribute to increase team viability and the quality of the group experience. 相似文献

Recently, electrophysiological measures have been used to evaluate the functional overlap between semantic relations and laboratory-defined equivalence relations with abstract stimuli. Several studies using semantic judgment procedures have shown that accompanying EEG-measured neural activity for stimulus pairs from equivalence classes is very similar to that of word pairs from participants' native language. However, those studies often included pronounceable elements (e.g., written nonsense syllables) as at least one member of the experimentally defined classes. The present study conducted EEG studies that contrasted classes with and without such elements. Two groups of undergraduate students completed a matching-to-sample procedure to establish 3 4-member equivalence classes. For Group 1, samples and comparisons were pronounceable pseudowords and abstract figures. For Group 2, the matching-to-sample stimuli were abstract figures only. EEG data recorded during the semantic judgment tasks showed waveform patterns compatible with prior studies of semantic relations in Group 1 but not in Group 2. 相似文献

This article describes the development and validation of a theory-based measure of team development. Drawing on 3 independent samples, including multisource and 2-wave data, we found support for the scale’s theoretical multidimensionality. Convergent and discriminant validity was established, and criterion-related validity was determined through the scale’s relation with 3 facets of team effectiveness: viability, extrarole performance, and reputation. We conclude that the 29-item measure is valid and reliable for the assessment of team development. Theoretically, we shed light on the dimensionality of team development and extend the available knowledge on its nomological network. Practical implications for enhancing team effectiveness via team development are discussed. 相似文献

The present paper is focused on the evolution of the position of the Catholic Church toward psychoanalysis. Even before Freud's The Future of an Illusion (1927), psychoanalysis was criticized by Catholic theologians. Psychoanalysis was viewed with either contempt or with indifference, but nonpsychoanalytic psychotherapy was accepted, especially for pastoral use. Freudian theory remained for most Catholics a delicate and dangerous subject for a long time. From the center to the periphery of the Vatican, Catholic positions against psychoanalysis have varied in the way that theological stances have varied. In the middle decades of the twentieth century, some Catholics changed their attitudes and even practiced psychoanalysis, challenging the interdict of the Holy Office, which prohibited psychoanalytic practice until 1961. During the Cold War, psychoanalysis progressively became more and more relevant within Catholic culture for two main reasons: changes in psychoanalytic doctrine (which began to stress sexuality to a lesser degree) and the increasing number of Catholic psychoanalysts, even among priests. Between the 1960s and the 1970s, psychoanalysis was eventually accepted and became the main topic of a famous speech by Pope Paul VI. This paper illustrates how this acceptance was a sort of unofficial endorsement of a movement that had already won acceptance within the Church. The situation was fostered by people like Maryse Choisy or Leonardo Ancona, who had advocated within the Church for a sui generis use of psychoanalysis (e.g., proposing a desexualized version of Freudian theories), despite warnings and prohibitions from the hierarchies of the Church. 相似文献

This article briefly outlines a picture of the activities and research conducted in Italy on the history of psychology during the last 10 years, focusing its attention on institutions, scholars, conferences, archives, journals, and so forth. At the dawn of the 21st century, the tradition of historical-psychological studies that developed in the last quarter of the 20th century has led to a renewed situation in teaching organization and research, with the emergence of several groups, especially at the universities of Rome "Sapienza", Bari, Milan-Bicocca, and Urbino, and of a second generation of young historians increasingly engaged on an international level. After a general survey conducted with historiometric method on the principal areas of research cultivated and on the themes dealt with, we mention a change that has occurred in the historiographical approach, a transition from a historiography addressed prevalently to the "history of ideas" to one that, pursuing the approach of a new and critical "multifactorial" history, proves to be more attentive to the social and institutional history, in correspondence with established international trends. 相似文献

The fuzzy perspective in statistical analysis is first illustrated with reference to the “Informational Paradigm” allowing
us to deal with different types of uncertainties related to the various informational ingredients (data, model, assumptions).
The fuzzy empirical data are then introduced, referring to J LR fuzzy variables as observed on I observation units. Each observation is characterized by its center and its left and right spreads (LR1 fuzzy number) or by its left and right “centers” and its left and right spreads (LR2 fuzzy number). Two types of component models for LR1 and LR2 fuzzy data are proposed. The estimation of the parameters of these models is based on a Least Squares approach, exploiting
an appropriately introduced distance measure for fuzzy data. A simulation study is carried out in order to assess the efficacy
of the suggested models as compared with traditional Principal Component Analysis on the centers and with existing methods
for fuzzy and interval valued data. An application to real fuzzy data is finally performed.
We would like to express our gratitude to the Editor, the Associate Editor, and the Referees whose comments and suggestions
improved significantly the quality of the paper. 相似文献
