Restauro architettonico, ricerca, didattica: risultati dal primo decennio di esperienza del corso di Ingegneria Edile-Architettura (2012-2022)
No full textKnowledge and respect are the essential combination to guarantee targeted and respectful restoration of the
architectural heritage. Same principles are essential also for the planning of enhancement interventions capable of
giving new life to the buildings and guaranteeing their conservation in full respect of their artistic significance, of
the material value and specific architectural connotations. This contribution presents some results of research
experiences conducted in the Roman and Lazio area as part of the Course of Architectural Restoration in the decade
2012-2022, at the Faculty of Engineering of the University of Rome Tor Vergata. Theory and practice of
architectural restoration of archaeological sites of Tivoli and Palestrina, churches, palaces, so-called minor
buildings, villages and historic centres of Lazio had be illustrated using a unique method of investigation, based
on principles and guidelines operative of the Italian restoration. These research topics, carried out in cooperation
with a number of prestigious Italian Research Institutes and Superintendencies, have been explored in depth in
degree and doctoral theses, also touching on the complex problem of the relationship between historic buildings
and plant upgrades. The results achieved, some published, demonstrate the usefulness of a possible coexistence
between historical-artistic sensitivity, technical knowledge and new uses of the architectural heritage
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
Differential impairment of interhemispheric transmission in bipolar disease.
No full textThere is abundant evidence that the cerebral white matter and in particular the corpus callosum show several structural abnormalities in both schizophrenia (SCZ) and bipolar disease (BD). However, which cognitive functions are impaired as a result of these anomalies is still unclear. Previous behavioural tests of interhemispheric crosstalk have shown a differential impairment in SCZ with interhemispheric transmission time, as tested with the Poffenberger paradigm, essentially normal but with an abnormally enhanced interhemispheric summation effect, as tested with the redundant signal effect. The present study was inspired by this discrepancy and by the more general question of a possible overlap between the pathophysiology of SCZ and BD. We tested both SCZ and BD patients in the Poffenberger paradigm and redundant signal effect and found a similar dissociation, namely a normal interhemispheric transfer time and an abnormal redundant signal effect. The only difference between the two groups was a selective slowing of speed of response of the dominant right hand in the SCZ group suggesting an impairment of left hemisphere functions. These results cast further light on the question of common and differential impairments of basic psychological functions in the two diseases
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
Protection of gender health and fght against gender violence during the COVID-19 pandemic: the experience of our street clinic in a disadvantaged suburb of Rome Metropolitan City
Full text linkObject
In this study, we evaluated health, social inequalities and risk to gender violence of women living in a disadvantaged degraded suburb of Rome Metropolitan City, during COVID-19 pandemic.
Methods
The study included 779 women referring to primary care services of Medicina Solidale Institute for gynecological/breast examinations (209), medical and support aid for the children (383) and COVID-19 test execution (187).
Results
The data show that most women (68%) were unemployed or had an irregular job. The request of support varied depending on the ethnicity: while healthcare support was requested mostly by African female community, the COVID-19 test, mandatory for public transportation and work, was a need of the east-european community. Both these communities referred to Medical Solidale primary care service for the healthcare and food/clothing support for their children.
It is interesting to note that the requests from the Italian women community was elevated in terms of personal healthcare, support for the children and COVID-19 test execution.
The access to the national health system (NHS) resulted a complex administrative procedure despite the original social-ethnic communities. The vast majority of women lacked awareness of their crucial role for supporting the family entity, while inadequacy was commonly reported.
Conclusions
This study confirms a critical condition for women living in disadvantaged neighborhoods, whose vulnerability is further worsened by the limited access to primary care assistance with serious consequences for health and quality of life. Prevention and treatment, especially for the most vulnerable subjects, should be a priority for the public health system
Enhanced redundancy gain in schizophrenics: A correlate of callosal dysfunction?
No full textAn abnormal pattern of hemispheric asymmetry, possibly as a result of disturbed interhemispheric communication, is widely, albeit by no means unanimously, held as a major cause of schizophrenia. To behaviourally test interhemispheric communication in schizophrenia we used a task that has been shown to be a reliable indicator of callosal functioning, namely, the redundant signals effect (RSE). It consists of the speeding of simple reaction time when responding to double as opposed to single visual stimuli. When the stimuli in a pair are presented to different hemispheres patients who underwent total commissurotomy or suffer from callosal agenesis show a paradoxically enhanced RSE with respect to healthy controls. Therefore, if schizophrenia patients have a callosal abnormality they ought to show a similar effect. In three experiments we tested a total of 55 patients with a diagnosis of schizophrenia and 51 healthy controls. In Experiment 1 we presented unilateral single stimuli and bilateral simultaneous double stimuli. The RSE was reliably larger in schizophrenics than in controls. In Experiment 2 the temporal interval between the two stimuli in a pair was varied. We found that while in controls the RSE disappeared with interstimulus intervals longer than 17ms, in schizophrenia patients there was a RSE only for simultaneous double stimuli. Finally, in Experiment 3 we found that there was no enhanced redundancy gain in schizophrenics when the double stimuli were presented to one and the same hemisphere, and therefore, with no need for callosal transmission. All in all, the present results provide evidence of a callosal dysfunction in schizophrenia that impairs interhemispheric integration
