The spatial association of the mathematical symbols «minus and plus»
Full text linkThe influence of spatial-numerical associations in number categorization tasks has been widely discussed, while the role of mathematical symbols is less clear. Specifically, it has been demonstrated that subtraction and addition, reducing and increasing the magnitude of numbers, are associated with left and right space, respectively. This result is explained by invoking a mental number line or a semantic association. The present work investigated the role of the mathematical symbols «minus and plus» presented as fixation points in a spatial compatibility task. Results demonstrated an opposite influence of the two symbols: the processing of the «minus» facilitated responses to the target presented on the left, while the «plus» facilitated responses to the target presented on the right
Il caso Tetra Pak Carton Ambient
No full textTetra Pak Carton Ambient costituisce per la ricerca complessiva sulla qualità del lavoro in provincia di Modena un caso significativo per diversi elementi. La presenza nell’ente di politiche che favoriscono la conciliazione fra tempi di vita e di lavoro, l’adozione di sistemi innovativi di gestione del personale e di accordi contrattuali con riferimento alla gestione dei tempi, alla variabilità retributiva e alle forme non standard di lavoro. L’indagine sulla qualità del lavoro al suo interno quindi potrebbe fornire spunti di riflessione su come queste politiche possano influire su diverse dimensioni della qualità del lavoro ricostruite sia utilizzando indicatori oggettivi che le valutazioni soggettive espresse dai lavoratori e dalle lavoratrici che hanno preso parte all’indagine
Varieties of abstract concepts and their multiple dimensions
Full text linkThe issue of how abstract concepts are represented is widely debated. However, evidence is controversial, also because different criteria were used to select abstract concepts - for example, imageability and abstractness were equated. In addition, for many years abstract concepts have been considered as a unitary whole. Our work aims to address these two limitations. We asked participants to evaluate 425 abstract concepts on 15 dimensions: abstractness, concreteness, imageability, context availability, Body-Object-Interaction, Modality of Acquisition, Age of Acquisition, Perceptual modality strength, Metacognition, Social metacognition, Interoception, Emotionality, Social valence, Hand and Mouth activation. Results showed that conceiving concepts only in terms of concreteness/abstractness is too simplified. More abstract concepts are typically acquired later and through the linguistic modality and are characterized by high scores in social metacognition (feeling that others can help us in understanding word meaning), while concrete concepts obtain high scores in Body-Object-Interaction, imageability, and context availability. A cluster analysis indicated four kinds of abstract concepts: philosophical-spiritual (e.g., value), self-sociality (e.g., politeness), emotive/inner states (e.g., anger), and physical, spatio-temporal, and quantitative concepts (e.g., reflex). Overall, results support multiple representation views indicating that sensorimotor, inner, linguistic, and social experience have different weights in characterizing different kinds of abstract concepts
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
