Gaussian Groups and Garside Groups, Two Generalisations of Artin Groups
1999
It is known that a number of algebraic properties of the braid groups extend to arbitrary finite Coxeter-type Artin groups. Here we show how to extend the results to more general groups that we call Garside groups. Define a Gaussian monoid to be a finitely generated cancellative monoid where the expressions of a given element have bounded lengths, and where left and right lowest common multiples exist. A Garside monoid is a Gaussian monoid in which the left and right lowest common multiples satisfy an additional symmetry condition. A Gaussian group is the group of fractions of a Gaussian monoid, and a Garside group is the group of fractions of a Garside monoid. Braid groups and, more genera…
Research Note: Reciprocal Effects of Negative Press Reports
2007
A B S T R A C T ■ The influence of negative press reports on their subjects was determined by means of a questionnaire answered by 91 persons who had complained about such reports to the Deutsche Presserat (German Press Council). The findings show that negative press reports have long-lasting emotional and social consequences, as perceived by the subjects. Plausible interactions exist between these consequences. There is a theoretical basis for attributing both types of consequences to certain characteristics of the reports. ■
Social Animation in Complex Environments
2007
This work presents a market-based social model to produce good quality behavioral animations for groups of intelligent virtual agents. The social model coordinates the activities of groups of virtual characters and also includes social actions in the agent decision-making. We follow the Multi-Agent Resource Allocation approach presented in [2], where agents express their preferences using utility functions. The dynamics of social interactions is inspired by the theory of Piaget [3] over which we have implemented reciprocal task exchanges.
La comunità come rete di relazioni reciproche: percorsi collaborativi nella formazione iniziale degli insegnanti di sostegno
2017
Communities of practice can become a perfect place where teachers can reflect on their practice, share approaches, experiment with new content and new practices. The interaction between teachers in a community of practice encourages peer learning and stimulates problem solving. The present work, centered on the reciprocal teaching and project based learning methodologies, involved 195 disability and inclusion pre-service teachers and gave them the opportunity to experience the integration of the two teaching / learning models through which they learned how to collaborate and achieve results in effective way and working with others.
Pictorial meaning-making in a community project in Helsinki. Freirean interpretations of a dialogical process
2018
Participation in public discourse belongs to a democratic citizenship. However, part of the population is excluded from such communal discussion. This paper describes how the photography group Camera Obs., which principally contained unemployed people in Helsinki, created pictorial voices from their own everyday experiences through a dialogical process, rendering them also visible to other people. The research focuses on the group’s activity during the years 2004–6, from the beginning of the project to its first exhibition. As a theoretical background, Paulo Freire’s ideas of dialogue and voice creation, combined with Vygotsky’s and Mezirow’s concept of meaning-making, have been applied. T…
Reading Comprehension and Working Memory's Executive Processes: An Intervention Study in Primary School Students
2013
ABSTRA C T Reading comprehension is a highly demanding task that involves the simultaneous process of extracting and constructing meaning in which working memory’s executive processes play a crucial role. In this article, a training program on working memory’s executive processes to improve reading comprehension is presented and empirically tested in two experiments with third-grade primary school students. Experiment 1 showed a greater gain after training the experimental group in contrast to the control group in reading comprehension and intelligence. In experiment 2, we focused on the training processes and compared training results of high and low pretest reading comprehension groups. R…
Coordination and Sociability for Intelligent Virtual Agents
2008
This paper presents a multi-agent framework designed to simulate synthetic humans that properly balance task oriented and social behaviors. The work presented in this paper focuses on the social library integrated in BDI agents to provide socially acceptable decisions. We propose the use of ontologies to define the social relations within an artificial society and the use of a market based mechanism to reach sociability by means of task exchanges. The social model balances rationality, to control the global coordination of the group, and sociability, to simulate relations (e.g. friendliness) and reciprocity among agents. The multi-agent framework has been tested successfully in dynamic envi…
A qualidade do intercâmbio líder-membro (LMX) e o clima psicológico: Uma análise longitudinal das suas relações recíprocas
2014
Although the relationship between climate and leadership has been taken into account from different research and theoretical approaches, there is a lack of effort in the development of conceptual framework to understand the relationship between the development processes in both constructs. Grounding on the interactionist approach to the formation of climate and the Leader Member Exchange in leadership, Kozlowski and Doherty (1989) developed a conceptual framework that specifies the theoretical mechanisms linking both constructs. The lack of longitudinal designs hinders the possibility to test causal relationship between both constructs. The main objective of the present paper was to test a …
From Lattice Valued Theories to Lattice Valued Analysis
2015
We claim and justify that the future of a fuzzy logic is in the interconnection of various well-developed theories. We are focused on a lattice valued analysis that unifies the treatments of atomic elements, sets of atomic elements, functions between sets of atomic elements and their properties. We clarify the relationship between a fuzzy function and its ordinary core. We discuss the property of continuity of a fuzzy function in a lattice valued topology.
Exact Coulomb cutoff technique for supercell calculations in two dimensions
2009
We present a reciprocal space technique for the calculation of the Coulomb integral in two dimensions in systems with reduced periodicity, i.e., finite systems, or systems that are periodic only in one dimension. The technique consists in cutting off the long-range part of the interaction by modifying the expression for the Coulomb operator in reciprocal space. The physical result amounts in an effective screening of the spurious interactions originated by the presence of ghost periodic replicas of the system. This work extends a previous report [C. A. Rozzi et al., Phys. Rev. B 73, 205119 (2006)], where three-dimensional systems were considered. We show that the use of the cutoffs dramatic…
