The culture of communication in the public sector facing the challenge of digital media: an explorative research in Italy and France
No full textThe article focuses on the culture of communication in the public sector aiming at understanding its features and transformations facing the challenge of digital media. In the first part, a view of the international literature on communication in the public sector is presented. The strategic role played by communication in the public organizations is underlined as well as the institutionalization of social media in the management of communication with citizens and media.
In the second part, a qualitative explorative research is illustrated. The study was conducted in Italy and France and consisted of 10 in-depth interviews with key figures in public sector communication: academics and professionals of national associations
Paths of hybridization among journalism, politics, and public sector communication in Italy.
No full textThe article argues that in Italy there is a new problematic relationship among
journalism, politics, and public sector organizations due to the permanence of some
traditional features in the informative context as well as to the success of infotainment
logic and to the pervasive use of social media. In the new hybrid digital ecosystem,
a redefinition of the social role of information is necessary to understand the
perspectives for journalism and public sector communication. Infotainment and politainment
enhance the hybridization of Italian public sector communication formats
and styles mainly on social media platforms. This process has consequences on interactions
and overplays between information and communication areas in public
organizations, redefining the evolution of professional role
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
I disturbi di pensiero sottosoglia: un continuum con il delirio paranoideo? Il possibile ruolo dei bias euristici attributivi nel mantenimento dell'autostima
No full textObjectives: Human reasoning originates both as in a propositional way following the inferential laws of formal logic, as analogically according to Johnson-Laird Theory of Mental Models (TMM), with the construction of the premises through a mental model (in the form of representation of a specific problem), and subsequent manipulations until the review of the premises through the selection and reduction (contextual restrictors) of these models in comparison with evidence to the contrary (counterarguments). The aim of the present paper is to better understand if delusional thought (mainly of paranoid type) is at the end of the spectrum of heuristic thinking biases (in particular of social and attributional biases), rather than regard it as a discontinuity from the form of thought shared among individuals. Methods: Cochrane analysis of the literature with following key words: euristic biases, paranoid delusions, self-esteem, moral disengagement. Results: Literature data are sufficiently unique in considering that among the factors that interfere with the process of restriction, favoring the onset of delusional thinking, as well as some mental states (anger, mood swings, emotional lability, fear, anxiety), might be considered heuristic biases that are intended to preserve the self-esteem (either an overt or deep). Conclusions: The interest of our hypothesis is that what we consider to be clinically more severe (delusions) may in fact represent only the tip of the iceberg in a series of sub-threshold thinking disorders, which, just because it is very common and socially accepted, represent a more serious kind of human miscommunication, also justifying dangerous behaviour derived from moral disengagement. A unitary hypothesis that links sub-threshold thoughts disorder to delusions is that it serves to preserve our self-esteem, at least from a psychological point of view
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

No full textOn the role of tail in stability and energetic cost of bird flapping flight
No full textMigratory birds travel over impressively long distances. Consequently, they have to adopt flight regimes being both efficient-in order to spare their metabolic resources-and robust to perturbations. This paper investigates the relationship between both aspects, i.e., energetic performance and stability, in flapping flight of migratory birds. Relying on a poly-articulated wing morphing model and a tail-like surface, several families of steady flight regime have been identified and analysed. These families differ by their wing kinematics and tail opening. A systematic parametric search analysis has been carried out, in order to evaluate power consumption and cost of transport. A framework tailored for assessing limit cycles, namely Floquet theory, is used to numerically study flight stability. Our results show that under certain conditions, an inherent passive stability of steady and level flight can be achieved. In particular, we find that progressively opening the tail leads to passively stable flight regimes. Within these passively stable regimes, the tail can produce either upward or downward lift. However, these configurations entail an increase of cost of transport at high velocities penalizing fast forward flight regimes. Our model-based predictions suggest that long range flights require a furled tail configuration, as confirmed by field observations, and consequently need to rely on alternative mechanisms to stabilize the flight
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
