An Algebraic Approach to Knowledge Representation
1999
This paper is an attempt to apply domain-theoretic ideas to a new area, viz. knowledge representation. We present an algebraic model of a belief system. The model consists of an information domain of special kind (belief algebra) and a binary relation on it (entailment). It is shown by examples that several natural belief algebras are, essentially, algebras of flat records. With an eye on this, we characterise those domains and belief algebras that are isomorphic to domains or algebras of records. For illustration, we suggest a system of axioms for revision in such a model and describe an explicit construction of what could be called a maxichoise revision.
Dimensionality and factorial invariance of religiosity among Christians and the religiously unaffiliated: A cross-cultural analysis based on the Inte…
2019
We present a study of the dimensionality and factorial invariance of religiosity for 26 countries with a Christian heritage, based on the 1998 and 2008 rounds of the International Social Survey Programme (ISSP) Religion survey, using both exploratory and multi-group confirmatory factor analyses. The results of the exploratory factor analysis showed that three factors, common to Christian and religiously unaffiliated respondents, could be extracted from our initially selected items and suggested the testing of four different three-factor models using multi-group confirmatory factor analysis. For the model with the best fit and measurement invariance properties, we labeled the three resulting…
“Your ride has arrived” – Exploring the nexus between subjective well-being, socio-cultural beliefs, COVID-19, and the sharing economy
2021
This study aimed to identify and explain different facets of the sharing economy and to differentiate between micro- and macro-mobility services. We also aimed to examine the correlation between the sharing economy and subjective well-being, cultural beliefs, and COVID-19. An exploratory research technique with face-to-face semi-structured interviews was used to collect data from a sample of 22 rideshare app users in a developing country between January and May 2020 and in July 2020. The data were analyzed using the NVivo 12 application. The major findings suggest that, considering their scope and use, sharing economy technology and services can be divided into four major domains: (1) hospi…
THE DEVELOPMENT OF ADOLESCENTS’ SELF-CONCEPT OF ABILITY THROUGH GRADES 7-9 AND THE ROLE OF PARENTAL BELIEFS
2016
This study examined the development of adolescents’ self-concept of ability in mathematics and literacy during secondary school, and the role that mothers’ and fathers’ beliefs concerning their child’s abilities play in this development. Also examined was whether the role of mothers’ and fathers’ beliefs about their adolescent child’s ability in mathematics and literacy differs according to the adolescent’s gender and level of performance. A total of 231 adolescents and their mothers and fathers were followed up across secondary school. The results showed, first, that adolescents’ self-concept of ability declined slightly from grade 7 to grade 9 in both mathematics and literacy. Second, mot…
Influence Assessment in Twitter Multi-relational Network
2015
International audience; Influence in Twitter has become recently a hot research topic since this micro-blogging service is widely used to share and disseminate information. Some users are more able than others to influence and persuade peers. Thus, studying most influential users leads to reach a large-scale information diffusion area, something very useful in marketing or political campaigns. In this paper, we propose a new approach for influence assessment on Twitter network, it is based on a modified version of the conjunctive combination rule in belief functions theory in order to combine different influence markers such as retweets, mentions and replies. We experiment the proposed meth…
Italian Primary School prospective teachers beliefs about knowledge construction: a case study about models
2012
In this paper we discuss a study on the approaches to modeling of students of the 4-year Primary School Teacher program at the University of Palermo, Italy. The answers to a specially designed questionnaire are analyzed on the basis of an a-priori analysis made using a general scheme of reference on the epistemology of mathematics and physics. The study is performed by using quantitative data analysis methods, i.e. analysis of implicative and similarity trees. Dans ce papier, nous menons une étude relative à l’approche de la notion de modélisation par des étudiants de 4ème année de formation à la fonction de professeur d’école primaire à l’Université de Palerme, Italie. Les réponses à un qu…
A Lexicon for Italian cinema: A conversation about history, theory and critique
2017
This article represents the outcome of a round table organized and conducted by Giacomo Tagliani about the Lessico del cinema Italiano/Lexicon of Italian Cinema (2014–2016). This research and editorial project comprises three volumes and 21 entries that address the history of Italian cinema through an original and challenging approach, namely to detect a list of conceptual clusters able to provide new perspectives over the heritage of Italian films. In this refined version, the authors who took part in that round table, that is, Roberto De Gaetano (also editor of the volumes), Massimiliano Coviello, Luca Venzi and Francesco Zucconi, outline their involvement in the research project, their s…
Un Churel Mandir in Gujarat. Note sulla diffusione delle rappresentazioni della figura della strega in India
2021
The churels are figures of the folk imagery of a vast area of South Asia. They, commonly identified with witches, are spirits of women who died during pregnancy or childbirth, and who return to the world of the living, possessing them. The aim of this study is to provide an interpretative analysis of the representations of the churels and of the ambiguous climate that has been created around these figures in recent decades in India. A reflection on the power of the representations of the churels throughout history up to present-day India could be considered a key to penetrating the dense network of relationships and reinventions, but also of divergences and contradictions, sometimes with tr…
Decisional Procrastination in Academic Settings: The Role of Metacognitions and Learning Strategies
2017
Nowadays, university students suffer from a broad range of problems, such as educational underachievement or the inability to control themselves, that lead to procrastination as a consequence. The present research aimed at analyzing the determinants of decisional procrastination among undergraduate students and at assessing a path model in which self regulated learning strategies mediated the relationship between metacognitive beliefs about procrastination and decisional procrastination. 273 students from Southern Italy filled out a questionnaire composed by: the socio-demographic section, the Metacognitive Beliefs About Procrastination Questionnaire, the procrastination subscale of the Mel…
Cardiovascular Management Self-efficacy: Psychometric Properties of a New Scale and Its Usefulness in a Rehabilitation Context.
2015
Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Background: Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Purpose: The aims of this study were to present a new scale measuring self-efficacy beliefs in managing CVD and to examine its psychometric properties. Methods: The study involved 172 patients (mean age = 66.4…
