    Il presente lavoro di tesi ha come obiettivo lo studio aerotopografico di una porzione del Limes orientale compreso tra la media valle dell’Eufrate e il golfo di Aqaba mediante l’utilizzo sistematico di documentazione telerilevata storica e recente. Uno studio che si pone come analisi e sintesi di una serie di dati editi e soprattutto inediti relativi alle strutture fortificate e alle infrastrutture viarie che contraddistinguevano la frontiera romana. Nel dettaglio il lavoro prende le mosse dalle esplorazioni dell’archeologo ungaro-inglese Sir Marc Aurel Stein che, sulle orme di Padre Antoine Poidebard, tra il 1938 e il 1939 mise in atto un vero e proprio progetto di ricerca finalizzato allo studio dei centri antichi e della viabilità lungo il Limes orientale, compreso tra Iraq e Giordania, mediante l’uso sistematico di riprese aeree integrate da sopralluoghi finalizzati alla verifica a terra delle evidenze. Partendo proprio dalle ricerche e dal cospicuo materiale grafico (125 disegni) e fotografico (305 fotogrammi) di Stein, sono stati indagati un totale di 73 siti, geolocalizzati ed esaminati mediante l’utilizzo di foto cosmiche Corona KH-4B e Hexagon KH-9, ovvero mediante immagini storiche acquisite dai satelliti spia americani tra gli anni ’60 e gli anni ’80 del Novecento e oggi declassificate per uso civile. Queste immagini permettono di documentare insediamenti e relativi territori prima delle recenti trasformazioni, consentendone la contestualizzazione in un paesaggio storico molto vicino a quello antico. L’area d’indagine, nel dettaglio, fino alla prima metà del Novecento, era stata interessata da una scarsa antropizzazione, essendo inoltre per lo più abitata da popolazioni nomadi; mentre dal secondo dopoguerra, in questi territori si è assistito alla nascita e all’espansione di centri abitati, alla diffusione dell’agricoltura meccanizzata e alla realizzazione di infrastrutture che hanno modificato il paesaggio, talvolta distruggendo e obliterando numerose evidenze antiche. La fotointerpretazione delle foto cosmiche ha, pertanto, consentito una ricostruzione del paesaggio, il più vicino possibile a quello documentato da Stein e dunque anche a quello storico, e ha inoltre permesso di esaminare lo stato di conservazione delle rovine, verificabile per i tempi recenti sulle immagini satellitari ad alta e altissima risoluzione. Alla luce di quanto esaminato nel lavoro, si è avuto modo di constatare che su 73 casi studio analizzati, 34 sono strettamente correlati alla frontiera romana, rappresentata da forti e fortezze che attestano le tre principali fasi di edificazione e strutturazione del Limes, avvenute rispettivamente in età traianea (fine I-inizi II d.C.), severiana (fine II- inizi III d.C.) e dioclezianea (fine III-inizi IV d.C.). Nel presente lavoro, in particolare, si è andato a confermare un quadro squilibrato fra le evidenze archeologiche relative alle guarnigioni di età traianea, per le quali si registra soltanto un caso studio, e quelle di età severiana e tetrarchica, per le quali invece, si registrano diverse attestazioni. Per quanto riguarda invece l’analisi dei restanti insediamenti, l’esame territoriale, eseguito sulle foto cosmiche, relativamente a contesti ed emergenze apparentemente non legate al Limes, hanno portato ad esplorare e individuare aree, percorsi viari e strutture fortificate, talvolta note, ma le cui tracce oggi non sono più leggibili, e talvolta completamente sconosciute. Partendo dalle necessarie premesse relative alla natura e alla storia del Limes e analizzando con una mentalità critica le tracce leggibili dalla documentazione satellitare storica, sono stati raccolti numerosi dati editi e, soprattutto, inediti. Infine, la creazione di una piattaforma GIS appositamente dedicata rende, come fine ultimo, questo lavoro un vero e proprio strumento di ricerca per la conoscenza del Limes, dal quale ripartire e da incrementare con il prosieguo delle ricerche.The objective of this thesis is to undertake an aerotopographic study of a section of the Roman Eastern Limes, situated between the middle valley of the Euphrates and the Gulf of Aqaba. This was achieved through the systematic utilisation of historical and contemporary remote sensing documentation, obtained from aerial and satellite platforms. The study serves to provide an analysis and synthesis of a series of published and particularly unpublished data pertaining to the fortified structures and road infrastructures that characterised the Roman frontier. The thesis work is based on the explorations of the Hungarian-English archaeologist Sir Marc Aurel Stein, who, following in the footsteps of Father Antoine Poidebard, carried out a study mission in 1938-1939. This initiative sought to investigate historic centres and routes along the Roman Eastern Limes, which connects Iraq and Jordan and it employed a systematic use of aerial photography in conjunction with ground surveys. Based on Stein's research and extensive graphic material (125 drawings) and photographic material (305 frames), 73 sites were explored, geolocated, and evaluated using Corona KH-4B and Hexagon KH-9 cosmic photographs. These are historical photographs obtained by American spy satellites during the 1960s and 1980s that have recently been declassified. These images enable the documentation of towns and their respective regions prior to recent modifications, allowing them to be contextualised in a historical setting that is remarkably similar to the ancient one. Until the first half of the twentieth century, the area under investigation had experienced limited anthropization, with nomadic populations occupying the majority of the territory; however, since the post-World War II period, settlements have emerged and expanded, mechanised agriculture has spread, and infrastructures have been built, altering the landscape and sometimes destroying and obliterating numerous ancient remains. The photointerpretation of cosmic photos has thus allowed for a reconstruction of the landscape as close as possible to that documented by Stein and thus to the historical one, as well as the examination of the ruins' state of preservation, which has recently been verified through high and very high-resolution satellite images. According to the findings of the study, 34 of the 73 case studies examined are closely related to the Roman frontier, represented by forts and fortresses that attest to the three main phases of construction and structuring of the Limes, which occurred respectively in the Trajanic period (late 1st-early 2nd century AD), Severan period (late 2nd-early 3rd century AD), and Diocletian period (late 3nd-early 4rd century AD). In particular, the current study indicates a disparity between archaeological evidence related to Trajanic garrisons, for which only one case study is recorded, and those from the Severan and Tetrarchic periods, for which many attestations are recorded. With regard to the remaining settlements, the territorial examination conducted on cosmic photos concerning contexts and emergencies seemingly unrelated to the Limes has yielded the exploration and identification of areas, roadways, and fortified structures. Among these are known entities whose traces are no longer legible today, and others that are completely unknown. Starting from the necessary premises concerning the nature and history of the Eastern Limes and analysing with a critical mind the traces readable from historical satellite documentation, numerous published and, above all, unpublished data were collected. Finally, the creation of a specially dedicated GIS platform makes this work a true research tool for the knowledge of the Limes, from which to start and to increase as research continues

    IL LABORATORIO CARTOLAB NEL POST SISMA AQUILANO: RICERCA E PARTECIPAZIONE ALL’INTERFACCIA TRA POLITICA E SOCIETÀ

    No full text
    Nel contesto aquilano post sisma, a partire dai primi mesi del 2010, alcuni ricercatori del Dipartimento di Scienze umane dell’Università dell’Aquila, in particolare del Laboratorio Cartolab, hanno sviluppato e applicato (con il coinvolgimento di studenti e cittadini) una metodologia di ricerca-azione partecipativa/partecipante (RAPP) al contempo scientifica e politica. Dal punto di vista prettamente conoscitivo, la ricerca, in generale, si propone di far emergere e monitorare nel tempo, le percezioni e le narrazioni che i singoli e le comunità elaborano del proprio contesto di vita al fine di valutare la qualità del rapporto che, nello specifico contesto dell’Aquila post terremoto, si è andato instaurando tra il territorio e i suoi abitanti. Dal punto di vista dell’etica del ricercatore, invece, la RAPP si propone di orientare la prassi della ricerca verso l’attivazione di dinamiche sociali e/o politiche attraverso processi di comunicazione. L’intento di queste pagine è di fornire una illustrazione della RAPP per come finora è stata concretamente applicata nel contesto post sisma aquilano. Presentando all’occorrenza anche alcuni dei risultati conoscitivi più significativi sulla nuova geografia sociale dell’Aquila, un’attenzione particolare è posta sulla funzione della cartografia e dei GIS nelle varie fasi della ricerca

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    “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

    We 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

    Social and scholar integration and students satisfaction: the mediating role of career adaptability

    Full text link
    In the educational research, most of studies considered the quality of stu-dents life, focusing on several variables (Soresi et al., 2012; Tomyn and Cum-mins, 2011). Despite of it, there isn't evidence about the adaptability tofuture career as a mediator between integration at school and students satis-faction. This paper contributes to literature in two ways: rst it explores therole of career adaptability as a mediator, and this represents an innovativetopic because the concept and the operationalization of the career adapt-ability are recently developed, secondly, it can enhance the knowledge abouteducational research on career adaptability. This knowledge can be usedby teachers and practitioners to improve promotion and prevention focus asuseful strategies in scholar retention. The aim of the study is to explore themediating role of Career adaptability on the relationship between scholar andsocial integration and students satisfaction, which is considered a positiveoutcome related to learning achievement, scholar performance and educa-tional progress. Participants were 407 students from public high schools inthe South of Italy. Findings evidenced that Career Adaptability mediatedthe relationship between the social integration but not scholar integration,and students overall satisfaction. Implications for educational practice andlimitations of the study are discussed

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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 text
    We 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
