    No full text
    Si è ritenuto indispensabile affiancare alla storia di medici con l’Africa una breve storia dell’Africa, divisa per decenni, proprio per spiegare il contesto in cui l’ong si è trovata ad operare. Gli ultimi ’60 anni sono stati molto importanti per l’Africa, sono stati gli anni in cui è finito il dominio coloniale e in cui gli africani hanno cercato di riaffermare la loro identità. La spartizione e la colonizzazione da parte delle maggiori potenze europee è stata legalizzata dalla conferenza di Berlino (1884-85) tanto che nel 1914 solo il 5% del territorio africano (Liberia ed Etiopia) era indipendente. Con la fine della I g.m. , i 14 punti di Wilson, la nascita della S.d.N e l’istituzione dei mandati si fermava la fase ascendente dell’imperialismo coloniale. Non ci saranno più ingrandimenti territoriali (fatta eccezione per la riconquista italiana della Libia e l’occupazione dell’Etiopia) e la Germania, uscita sconfitta dalla guerra, perdeva i suoi territori che, in base al nuovo istituto della S.d.N., venivano affidati in mandato a Francia, Inghilterra e Belgio. Le potenze coloniali organizzavano i loro imperi e miravano essenzialmente ad una politica di sfruttamento economico mentre gli africani portavano avanti le loro idee di riscatto attraverso il panafricanismo, la negritudine, i nazionalismi e la formazione dei primi partiti politici. La II g.m. sarà determinante per la grande evoluzione verso l’indipendenza

    Gestione del paesaggio montano (i tempi della natura e i tempi dell’uomo)

    A vent'anni dalla stesura della Direttiva Habitat i suoi principi fondanti sono più che mai attuali ma non sempre risultano osservati adeguatamente. Meriterebbe maggiore attenzione la salvaguardia degli habitat seminaturali, la scelta dei siti Natura 2000 non è stata sempre fatta in un'ottica di rete ecologica, la gestione proposta non sempre risulta coerente con le attività delle popolazioni residenti

    Role of initial iodine-131 whole-body scan and serum thyroglobulin in differentiated thyroid carcinoma metastases

    evaluated the role of first I-131-whole-body scan and of first serum thyroglobulin (Tg) measurement after surgery in the early diagnosis of metastases from differentiated thyroid carcinoma (DTC). Methods: In 269 patients with metastases from DTC, we retrospectively evaluated the results of first whole-body scan (performed 40 days after surgery with diagnostic or therapeutic I-131 dose) and in 69 of them we also evaluated the result of first Tg measurement (performed the day before the first whole-body scan) in relation to the presence, localization and type of metastases. Results: In all patients, the first whole-body scan was positive for the thyroid remnant, and in 54.3% of patients it was also positive for metastases. In the remaining 45.7% of patients, metastases were detected during the follow-up. First Tg levels were >60 ng/ml in 66.7% of patients with metastases. First whole-body scan detected metastases in 47.8% of patients with Tg values 60 ng/ml in 61.3% of patients with first whole-body scan negative for metastases. The combined results of both first whole-body scan and first Tg measurement allowed the early detection of metastases in 82.6% of patients. Whole-body scan detected distant metastases more frequently than local lymph node metastases (p < 0.01). Conclusion: In more than 80% of patients, metastases were suspected or diagnosed as early as 40 days after surgery in the presence of residual thyroid tissue by combined evaluation of results of first whole-body scan and Tg measurement

    Variations on the Author

    “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

    Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation

    No full text
    The desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
