Stato, mercato, geopolitica. Le privatizzazioni in Italia (1992-2002) in un'ottica di interesse nazionale
Full text linkLo scritto che viene presentato si concentra sull’analisi delle privatizzazioni italiane degli anni Novanta (1992-2002), osservandone la traiettoria in un’ottica di «interesse nazionale».
La domanda di partenza, infatti, è: nel momento in cui lo Stato andava perdendo il diretto controllo su settori anche strategici della propria industria, la classe dirigente allora al potere si pose il problema – di natura geopolitica o, più precisamente, «geoeconomica» – di una eventuale e conseguente minaccia per l’interesse nazionale? Da tale quesito, poi, ne sorgono inevitabilmente degli altri, legati. Se così fu, quali adattamenti vennero individuati per rimediare ai rischi potenziali derivanti da tale complessa dinamica? Esisteva allora un disegno complessivo di politica industriale che si intendeva perseguire a livello istituzionale, in maniera organica? Nella scelta definitiva di privatizzare largamente la grande industria pubblica italiana incisero in maniera determinante fattori di natura ideologica?
Con la fine della Guerra Fredda, in una fase di radicale ridefinizione dei rapporti internazionali, il confronto geopolitico in atto si andava trasmettendo sempre più dalla sfera militare a quella economico-produttiva. Analizzando fonti primarie (Carte Prodi, Carte Delors, Carte Padoa-Schioppa, dall’Historical Archive of the European Union di Firenze) e secondarie (rapporti ministeriali, dibattiti parlamentari, sedute di commissione, giornali e riviste d’archivio), si scoprirà come il tema emerse in maniera estremamente significativa presso determinati ambienti politici e intellettuali italiani e condusse a scelte e adattamenti di grande rilievo (talvolta persino sorprendenti) per quanto sino ad oggi generalmente poco trattati in ambito storiografico
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Intraductal oncocytic papillary neoplasm (IOPN): two case reports and review of the literature
Full text linkBackground: Intraductal oncocytic papillary neoplasms (IOPNs) place at the oncocytic extreme of the intraductal pancreatic neoplasm spectrum and display typical morphological features. Their identification in 1996 by Adsay et al. has been followed by a growing number of cases, paving the way for a deeper understanding of this underestimated entity. Contrarily to intraductal papillary mucinous neoplasms (IPMNs), most IOPNs run an indolent course and surgery is usually curative. Pancreatic IOPNs tend to develop from the main pancreatic duct (MPD) and their diagnosis is either incidental or subsequent to mass-related symptoms. Up to 30% of cases show concomitant areas of minimal stromal invasion and loco-regional or systemic spread are confined to a minority of cases. Biological hallmarks of IOPNs are being identified, including recurrent kinase gene rearrangements. Morphological and biological traits of IOPNs seem to overlap with those of other malignancies. A deeper understanding of these entities is needed in order to shed light upon the nature of pancreato-biliary oncocytic neoplasms. This case report describes two patients with a diagnosis of IOPN-one of them accounting for the largest IOPN ever described-and provides a brief review of recent discoveries on the subject. Case description: We describe two cases of IOPN occurring in adult male patients, respectively in their 60s and 70s. Both patients had unremarkable clinical history. In case 1 the diagnosis was coincidental to a right renal colic; case 2 complained a right lumbar pain radiating to the homolateral groin. In both cases imaging analyses revealed a voluminous pancreatic mass, posing the indication to laparoscopic pancreatectomy. Gross and histological features were consistent with the diagnosis of IOPN. Surgical margin were free from disease and the patient did not undergo further treatment. After a 10- and 7-month follow-up respectively, patients did not experience relapse. Conclusions: Recent immunohistochemical (IHC) and molecular data reveal unique characteristics of IOPNs, highlighting the substantial differences from IPMNs. Further research is needed in order to identify novel prognostic and predictive markers applicable to oncocytic neoplasms of the pancreato-biliary tract
FMARS: Annotating Remote Sensing Images for Disaster Management using Foundation Models
Full text linkVery-High Resolution (VHR) remote sensing imagery is increasingly accessible, but often lacks annotations for effective machine learning applications. Recent foundation models like GroundingDINO and Segment Anything (SAM) provide opportunities to automatically generate annotations. This study introduces FMARS (Foundation Model Annotations in Remote Sensing), a methodology leveraging VHR imagery and foundation models for fast and robust annotation. We focus on disaster management and provide a large-scale dataset with labels obtained from pre-event imagery over 19 disaster events, derived from the Maxar Open Data initiative. We train segmentation models on the generated labels, using Unsupervised Domain Adaptation (UDA) techniques to increase transferability to real-world scenarios. Our results demonstrate the effectiveness of leveraging foundation models to automatically annotate remote sensing data at scale, enabling robust downstream models for critical applications
