Protection, management and planning: ragioni, pratiche ed effetti della tutela del paesaggio
Full text linkL'editoriale introduce il numero monografico con lo stesso titolo, riflettendo sulle tre politiche del paesaggio indicate dalla Convenzione Europea del Paesaggio. L’attenzione va in particolare alla tutela, mettendo in tensione due modi di intenderla: come domanda sociale e cura, a partire dalle attribuzioni di valore, e come attività tecnica, iscritta in un perimetro normativo e procedurale (i beni paesaggistici, le normative dei piani, le procedure autorizzative, ecc.). Si discute e mette reciprocamente in relazione la dimensione pre-giuridica dell’istanza di tutela le forme in cui si esprime, le attività tecniche che la sorreggono, gli effetti che ne scaturiscono, le possibilità di intervento progettuale ed evolutivo

Un progetto di (ri)generazione a Vallesina di Valle di Cadore: le concatenazioni dei valori patrimoniali e delle prospettive di fruizione turistica
No full textIl villaggio di Vallesina è una frazione del comune di Valle di Cadore, nel territorio dolomitico bellunese, situata poco discosto dalla strada statale d’Alemagna, che conduce alle mete turistiche più rinomate e a Cortina d’Ampezzo, e dalla Ciclabile delle Dolomiti, itinerario volto a promuovere nuove forme di mobilità lenta nell’area. In
passato luogo di fiorenti attività economiche, legate allo sfruttamento della forza idraulica del Rio Vallesina, e all’incrocio tra percorsi longitudinali e trasversali rispetto alla valle principale, negli ultimi decenni il borgo ha vissuto le dinamiche tipiche dell’abbandono delle località marginali. Attraverso un progetto Interreg da poco concluso, è stato possibile affiancare alle azioni di ripristino di un antico sentiero un percorso di ricerca volto a far emergere il valore patrimoniale multiforme e articolato del paesaggio locale per una sua valorizzazione. Il contributo presenta questo caso di studio e in particolare le concatenazioni dei valori patrimoniali che sono emerse durante la ricerca e che vanno a configurare il paesaggio di Vallesina; inoltre, vengono messe in evidenza le potenzialità e i limiti di questo progetto nell’ambito del sistema delle mobilità turistiche dell’area
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
Comparative mapping of the prion gene (PRNP) locus in cattle, sheep and man with PCR-generated probes
No full textPrions are the unconventional causative agent of sub-acute transmissible spongiform encephalopathies in human and various mammals; for example, Scrapie of sheep, Bovine Spongiform Encephalopathy (BSE) of cattle, Cruetzfeldt-Jakob disease (CJD) and Fatal Familial Insomnia (FFI) of human (Prusiner 1994). These
diseases are characterized by the accumulation in the brain tissue
of a prion protein, PrPSc that is a partially proteinase-resistant
isoform of the cellular protein, PrPc. Prions are the product of a
single gene that is highly conserved in mammals. Hamster prion
gene is composed of two exons; the entire coding region of the
gene is contained within the second exon (Goldfarb et al. 1991).
On the contrary, the genes of human, cattle, sheep, rat, and mouse
have three exons, with the entire protein-coding region contained
within exon 3 (Inoue et al. 1997). Cytogenetic analysis of the prion
genes has been reported in human, where the gene has been localized
on HSA 20p12-pter by a combination of somatic cell and
in situ hybridization (Sparkes et al. 1986). In cattle, the gene has
been mapped to syntenic group U11 (BTA 13) with a panel of
bovine–rodent hybrid somatic cells (Ryan and Womack 1993;
Hawkins et al. 1995) and has been recently incorporated into a
radiation hybrid framework map of BTA 13 (Shla ̈pfer et al. 1997).
Here we report the direct localization of the PrP gene in cattle,
sheep, and human by means of fluorescence in situ hybridization
(FISH) with PCR-generated probes
