Il perturbante nell'espansione urbana
No full textL'epoca ipermoderna, con le sue città enormi, altamente popolate, spersonalizzate e spersonalizzanti, è una fucina dei non-luoghi, dove si è costretti a vivere, ma che è impossibile abitare. Quali sono le conseguenze, sul piano psichico, di vivere in un luogo che è impraticabile, che evoca immagini di dolore, di evasione, che costituisce una minaccia, dove è impossibile rivelare la propria identità e la propria natura? Nella loro smisurata crescita le città hanno finito per perdere forma e identità, trasformandosi da luoghi comunitari in aggregati multiformi e dando spazio e nutrimento al perturbante urbanistico: periferie degradate, abbandono, miseria, sovrappopolamento, assenza di servizi e condizioni di vita difficili. Depressione, solitudine, senso di estraneità, perdita di identità e frammentazione sociale saranno i correlati psicologici dell'attuale modello di sviluppo, che costruisce luoghi privi di anima. Le ombre gettate dal perturbante dei luoghi prendono la forma di un'anestesia nei confronti dell'anima mundi, provocando la scissione tra Tecnica e Psiche, che così drammaticamente segna la nostra epoca
Body Anthropometry and Bone Strength Conjointly Determine the Risk of Hip Fracture in a Sideways Fall
Full text linkWe hypothesize that variations of body anthropometry, conjointly with the bone strength, determine the risk of hip fracture. To test the hypothesis, we compared, in a simulated sideways fall, the hip impact energy to the energy needed to fracture the femur. Ten femurs from elderly donors were tested using a novel drop-tower protocol for replicating the hip fracture dynamics during a fall on the side. The impact energy was varied for each femur according to the donor’s body weight, height and soft-tissue thickness, by adjusting the drop height and mass. The fracture pattern, force, energy, strain in the superior femoral neck, bone morphology and microarchitecture were evaluated. Fracture patterns were consistent with clinically relevant hip fractures, and the superior neck strains and timings were comparable with the literature. The hip impact energy (11 – 95 J) and the fracture energy (11 – 39 J) ranges overlapped and showed comparable variance (CV = 69 and 61%, respectively). The aBMD-based definition of osteoporosis correctly classified 7 (70%) fracture/non-fracture cases. The incorrectly classified cases presented large impact energy variations, morphology variations and large subcortical voids as seen in microcomputed tomography. In conclusion, the risk of osteoporotic hip fracture in a sideways fall depends on both body anthropometry and bone strength
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
Il suicidio fuori di sè. Una ricerca multidisciplinare
No full textIl suicidio è spesso definito come un momento estremo in cui si esce fuori di sé. Nell’Università degli Studi dell’Aquila, dopo tragici casi di colleghi, amici, studenti nel dipartimento MeSVA (Medicina clinica, sanità pubblica, scienze della vita e dell’ambiente) è stata svolta una ricerca sull’ipotesi che ogni suicidio abbia una fase ideatoria e preparatoria sulla quale sarebbe possibile intervenire. Attraverso la ricerca sono state messe a confronto competenze professionali relative a vari ambiti disciplinari. Inoltre, il volume mette in luce profili tematici poco esplorati: è soprattutto un tentativo per stimolare conoscenza e responsabilizzazione. Contro i comportamenti autodistruttivi le istituzioni possono fare molto in termini di comprensione e di prevenzione
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
