Categorising Perceptions af Danger and Risks. A Philosophical Perspective
Full text linkThe philosophical examination of danger and risk transcends practical statistical analysis and economic consequence, reflecting cultural values, emotions and cognitive processes. In essence, risk reflects not only material conditions but the values, fears, and aspirations of societies. This paper explores the multilayered nature of risk perception, emphasizing openness’ importance in nuclear energy’s controversial field.
Human responses to danger are influenced not only by immediate experience but also by collective memory and cultural heritage. This intersection of historical awareness and present realities creates a nuanced landscape, where nuclear science represents both a symbol of progress and a source of existential anxiety. Philosophical reflection thus becomes indispensable in disentangling these paradoxes and illuminating pathways through uncertainty. Risk is not merely an obstacle to progress; it is the very terrain where progress is negotiated. Risk embodies tensions between preservation and transformation, between the instinct to safeguard the present and the drive to innovate for the
future. Nuclear technologies exemplify this dual nature, representing both the dangers of hubris and the promise of sustainable advancement
How to recognise and avoid fallacies? Using audiovisual tools for logical education in schools
No full textWe present the results of the activity carried out by the University
of Cagliari in the context of the Italian POT project Oltre le due culture: per un dialogo interdisciplinare tra logica, filosofia e scienze della comunicazione.
The main purpose of the activity was to train high school students to use logical skills to recognise (and avoid) argumentative fallacies. The methodology in place was centered upon the use of audiovisual tools. The paper briefly surveys both argumentative fallacies and the use of audiovisual tools in schools, and then discusses the experiences
Fuzzy approach for C-NOT gate in quantum computation with mixed states
No full textIn the framework of quantum computation with mixed states, a fuzzy representation of CNOT gate is introduced. In this representation, the incidence of non-factorizability is specially investigated
Critical Thinking and Integrated Curriculum: Developing a lens to problematize their relationship in secondary education
No full textConscious citizenship and science education. Promoting students’ epistemic cognition through a taxonomy of epistemological obstacles
No full textLiving in the current information and knowledge-based society can be a
double-edged sword: the possibility of reaping benefits depends, to a large extent,
on the ability to decide who and what to believe, as well as on knowing how
to integrate multiple sources of information to gain consistent and expendable
knowledge, aimed at improving the quality of people’s personal and professional
life. This means that schools and other formal agencies should provide
learners with the analytical and critical tools necessary to effectively manage
the flow of information they are exposed to. In this context, the paper intends to
clarify under what conditions the integration of knowledge can foster a deeper
understanding of scientific rationality in students, allowing them to participate
in society as educated, informed and responsible citizens. For this purpose,
a project of a taxonomy of epistemological obstacles will be presented as an
example of an integrated approach to science teaching and learning, conceived
as a correlated system of products and expert practices
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
