IMMAGINI D’INFANZIA NEL FASCISMO TRA CINEMA E LIBRI DI TESTO
No full textThe article examines the figuration of childhood through a het-erogeneous set of texts and images from the fascist period.
The corpus analyzed, which includes documentaries, films, school books, exercise books and children's periodicals, consti-tutes a significant source of rhetorical strategies of representa-tion of the fascistization of children. These images, even in their multiple aspects, appear as a privileged observatory to capture in the icon of the ‘naturally fascist’ child the target of choice for the ideological diffusion and consolidation of the regime's he-gemony. Physical courage, muscular strength, love of military life, spirit of sacrifice, discipline, but also the distinction be-tween female and male childhoods, show an active and deep in-volvement of the new generations in the value system on which the dictatorship was based. To conquer the imagination of chil-dren, the first condition to guarantee the integral character of control and its projection into the future, childhood was cleverly depicted not only as a biological and sociological category, but also as a political and functional category for the nationalization of the people
Costruire apprendimento e partecipazione a scuola: da studenti unteachables a comunità di motivated learners
Full text linkEducation of the future is a central theme in many debates nowadays. This paper focuses on the question what knowledge and skills are most relevant to prepare students for a rapidly changing society and if schools are able to respond effectively to costant transformation driven by technological innovation. While the school systemis involved in a modification process that concerns its core contents, new “wired” generations of students from lower secondary education are labelled as difficult to teach or even “unteachables”, students who are losing interest in academic learning, who are not motivated or responsible for their learning processes. The contribution examines the activities of an ongoing Erasmus+ research project - Unteachables. Helping the new generations of school teachers turn increasingly unteachable young students into young Learnables -, which involves school students (aged 12-16), university master students, in-training teachers and university researchers from seven European countries, aimed at experimenting teacher training activities designed to involve students in creating communities of motivated learners. This paper, profiling unteachables students, highlights the need of innovative teaching methods that can enhance motivation and participation of students
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
Compressive yield stress of depletion gels from stationary centrifugation profiles
No full textWe have investigated the stationary sedimentation profiles of colloidal gels obtained by an arrested phase-separation process driven by depletion forces, which have been compressed either by natural gravity or by a centrifugal acceleration ranging between 6g and 2300g. Our measurements show that the gel rheological properties display a drastic change when the gel particle volume fraction exceeds a value φc , which barely depends on the strength of the interparticle attractive forces that consolidate the network. In particular, the gel compressive yield stress , which increases as for , displays a diverging behaviour for , with an asymptotic value that is close to the random close packing value for hard spheres. The evidence we obtained suggests that basically coincides with the liquid (colloid-rich) branch of the metastable coexistence curve, rather than with the lower (and φ-dependent) values expected for an attractive glass line penetrating inside the coexistence region

No full textProtein interactions near crystallization: a microscopic approach to the Hofmeister series
No full textThe salting-out effect of simple electrolytes on lysozyme has been studied by measuring the second virial coefficient B-2 Of the osmotic pressure as a function of salt concentration, and for different salts. The aim of this work has been to End a microscopic counterpart of the empirical Hofmeister series for the efficiency of cations and anions in inducing protein crystallization. The experimental results show that, for large enough ionic strengths, B-2 scales linearly with the salt concentration. This trend is common to a number of different monovalent salts, however with efficiency strongly dependent on the specific anion. Conversely, changing the cation does not appreciably affect B-2. The significance of these findings for the investigation-of protein interactions near crystallization is discussed
Multiscale relaxation in aging colloidal gels: From localized plastic events to system-spanning quakes
No full textRelaxation of internal stresses through a cascade of microscopic restructuring events is the hallmark of many materials, ranging from amorphous solids like glasses and gels to geological structures subjected to a persistent external load. By means of photon correlation imaging, a recently developed technique that blends the powers of scattering and imaging, we provide a spatially and temporally resolved survey of the restructuring and aging processes that spontaneously occur in physical gels originating from an arrested phase separation. We show that the temporal dynamics is characterized by an intermittent sequence of spatially localized "microquakes" that eventually lead to global rearrangements occurring at a rate that scales with the gel age. Notably, these dramatic upheavals of the gel structure are heralded by a progressive acceleration of the microscopic gel dynamics that originates from recognizable active spots and then spreads at a large but finite speed through the gel. Within the "slack" phase between two of these "macroquakes," the fluctuations of the degree of temporal correlation obey a non-Gaussian statistics described by a generalized logistic distribution. The evidence we obtained bear consistent analogies with the stress relaxation processes taking place in earthquake sequences and with the intermittent restructuring of plastic crystals at the microscale
