La prosa poetica di Alexander von Humboldt e il suo retaggio letterario, scientifico e politico
No full textLa portata “rivoluzionaria” dell’uomo e dello scienziato Alexander von Humboldt e della sua opera, capace di raccogliere l’eredità dei viaggiatori e degli scienziati di tempi precedenti e, al contempo, di sovvertirla in una nuova scrittura scientifica e, in senso ampio, politica, viene qui indagata relativamente al suo retaggio letterario, scientifico e politico. Lo scienziato prussiano, attraverso la sua intensa attività e altrettanto intensa scrittura, ha dato vita a una tradizione alla quale a lungo si sono ispirati scrittori e viaggiatori di lingua tedesca che, nella seconda metà dell’Ottocento, si cimentano in una serie di spedizioni esplorative, soprattutto rivolte al continente africano. Mossi dalla medesima sete di scoperta e di conoscenza del loro maestro, ma anche dall’ambizione di ottenere fama e riconoscimento da parte della comunità scientifica internazionale, autori come Georg Schweinfurth (1836-1925) finiscono con l’inserirsi in una realtà – quella della seconda metà del secolo – ormai profondamente mutata e che, con la fondazione del Deutsches Reich, è dominata da ambizioni di natura coloniale, in netto contrasto con i nobili e critici ideali dell’illustre modello. La controversa eredità humboldtiana, alla quale scienziati ed esploratori ottocenteschi si appellano, è qui indagata alla luce di un’affermazione di potere di natura imperialista, alla quale proprio Humboldt si era sempre chiaramente opposto
Two-dimensional semiconductor alloys: Monolayer Mo1-xWxSe2
No full textMonolayer Mo1-xWxSe2 (x = 0, 0.14, 0.75, and 1) alloys were experimentally realized from synthesized crystals. Mo1-xWxSe2 monolayers are direct bandgap semiconductors displaying high luminescence and are stable in ambient. The bandgap values can be tuned by varying the W composition. Interestingly, the bandgap values do not scale linearly with composition. Such non-linearity is attributed to localization of conduction band minimum states around Mo d orbitals, whereas the valence band maximum states are uniformly distributed among W and Mo d orbitals. Results introduce monolayer Mo1-xWxSe2 alloys with different gap values, and open a venue for broadening the materials library and applications of two-dimensional semiconductors
Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
Scrittori di libri nell’editoria del Novecento
No full textIl saggio esamina il ruolo dell’autore nell’editoria novecentesca, focalizzandosi su come molti scrittori non si siano limitati a comporre testi, ma abbiano anche partecipato attivamente alla progettazione materiale e editoriale dei propri libri. A partire dalle riflessioni di studiosi come Petrucci, Cadioli e Ferretti, è messo in luce quanto la figura del “letterato-editore” sia centrale nel Novecento italiano, e se ne seguono le evoluzioni attraverso casi emblematici come quello di Italo Calvino. L’intervento analizza le implicazioni filologiche e critiche della collaborazione autoriale alle scelte editoriali (dalla disposizione dei testi alle strutture peritestuali), sottolineando la rilevanza delle “variazioni d’autore” apportate agli indici delle diverse edizioni della stessa opera, ciascuna potenzialmente portatrice di un atto creativo a tutti gli effetti. L’intreccio tra le attività degli scrittori e quelle della redazione di una casa editrice viene letto come spazio privilegiato per comprendere la modernità letteraria, le trasformazioni dell’autorialità e il rapporto tra produzione editoriale e identità letteraria.The essay examines the role of the author in twentieth-century publishing, focusing on how many writers not only composed texts but also actively participated in the material and editorial design of their own books. Drawing on the reflections of scholars such as Petrucci, Cadioli, and Ferretti, the study highlights the centrality of the "writer-editor" figure in twentieth-century Italian literature, tracing its evolution through emblematic cases such as that of Italo Calvino. The article analyzes the philological and critical implications of authorial involvement in editorial decisions—from text arrangement to peritextual structures—emphasizing the significance of “authorial variations” introduced in the tables of contents across different editions of the same work, each potentially constituting a fully-fledged creative act. The intersection between the work of writers and that of editorial teams is interpreted as a privileged space for understanding literary modernity, transformations in the notion of authorship, and the relationship between editorial production and literary identity
Against purity : identity, western feminisms and Indian complications
No full textThis thesis argues that Western feminist theoretical models of identity can be
productively complicated by the insights of postcolonial feminisms. In particular,
it explores ways that Western feminist theory might more adequately sustain a
focus on 'women' while keeping open a space for differences such as race and
nation. Part One identifies a number of themes that emerge from recent Indian
feminist scholarship on the intersections of sex, gender, race, nation and
community identities. Part Two uses these insights to look critically at the work
of four Western theorists, Rosi Braidotti, Judith Butler, Donna Haraway and Luce
Irigaray. I argue that strategies which privilege sexual difference as primary
cannot deal adequately with differences such as race and nation. But I also argue
that strategies which privilege destabilizing identity can be equally constrained
by the logic of dualisms which has made it so difficult for feminists to sustain a
focus on women and their differences. Part Three discusses how the insights to
be drawn from Indian ferninisms might be taken on board by Western ferninisms
in order to develop more complex models of power, identity and the self.
Throughout the thesis I draw on a Foucauldian understanding of power as
productive, and on Foucault's insight that subjects and identities emerge, not
through the imperatives of a single symbolic system, but through the intersection
of multiple networks of discourses, material practices and institutions. I argue
that, by attending to women's complex location within intersecting landscapes of
gender, nation, race and other community identities, feminist models of identity
can dispense with a logic of dualisms in order to redefine, and not only
destabilize 'women' as the subject of/for feminism. This requires working against
purity on three levels. First, it requires a model of power that gives up on the
search for pure, power-free zones and works instead with the instabilities power
produces as it both enables and constrains women. Second, it requires seeing
'women' as a complex, impure category that bleeds across the apparently coherent
borders of identity categories such as gender, race and nation, and contesting
discursive constructs of 'Woman' as the pure space of origin upon which these
apparently discrete categories stand. Third, it requires the development of
alternative models of the self that take these complex, impure spaces as a valid
and valorised position from which to act and to speak
The classical and the grotesque in the work of Alexander Pope and Jonathan Swift
No full textThis thesis takes Mikhail Bakhtin's definitions of the classical and the grotesque, uses various
other theorists to problematise and extend these concepts through an engagement with gender
categories, and applies them to the work of Alexander Pope and Jonathan Swift. Although the first
part deals with the 'theory' of the classical and the grotesque, the following sections on Pope and Swift
seek to recognise the historical specificity and complexity of these modes as they intersect with the
cultural, material, and psychological circumstances of the writer. The methodology is not solely
biographical', 'political', 'cultural', 'feminist' or 'textual', but combines those approaches most relevant
to the particular text in question, sometimes engaging more directly with the political environment,
for example, at other times placing greater stress on mythological and generic allusions. The thesis
shows that the classical and the grotesque emerge from a long social and literary tradition, yet the
ways in which they manifest themselves in the time of Pope and Swift are very specific and
constructed at least partially in response to contemporary cultural contexts such as the publishing
trade, the present monarchy, the situation of Ireland and so on. Extending the work of Susan Gubar,
particular attention is paid to the figure of the female grotesque, a common and yet varied image that
is made to stand for a variety of cultural and moral ills in the writing of Pope and Swift. In contrast
the figure of the 'classical' woman or 'softer man' is found to be symbolic of order as the unruly
'natural' substance of woman is transformed into masculine 'Culture' through social and textual
containment. Classical and grotesque constructions of the masculine are also examined, especially in
relation to the author's perceptions of his own masculinity. The thesis concludes with a brief analysis
of the classical masculine friendship between Pope and Swift
Trailblazing through a Knowledge Space of Science: Forward Citation Expansion in CiteSeer
No full textUnderstanding emerging trends and patterns in science and technology is essential not only to scientists and engineers in their own fast-advancing fields but also to a wide variety of individuals and organizations who are also interested in tracking the development of thematic topics. This is a challenging task because many existing tools are not particularly designed to deal with the dynamics of intellectual structures that transcend the boundaries of individual documents or isolated topics. In this article, we introduce a conceptual and operational platform that extends the traditional notion of traveling along individual citation pathways and defines operators for recursive and holistic theme expansion based on citation connectivity. We describe the implementation of a forward expansion operator and illustrate its potential with the CiteSeer metadata. In addition, we integrate the forward expansion operators with information visualization techniques
Sobre a imortalidade
No full textEste discurso, encontrado entre os manuscritos de Berkeley, foi publicado pela primeira vez em 1871 por Alexander Campbell Fraser, em sua Collected Edition of the Works of Bishop Berkeley with Annotations.(LL pp. 598-604). No final do manuscrito, que atualmente se encontra no Museu Britânico, Berkeley registrou a data de 11 de janeiro de 1707/8. Berkeley tinha então 23 anos de idade. Isso indica que este discurso, próximo dos sermões que depois ele viria a escrever, foi escrito antes de ser ordenado diácono da Igreja da Irlanda na capela do colégio do Trinity College de Dublin em 19 de fevereiro de 1709. A tradução aqui apresentada baseia-se na edição organizada por Luce e Jessop. The Works of George Berkeley Bishop of Cloyne. Luce, A. A. and Jessop, T. E. London and Edimburgh: Nelson, 1948, v. 7, 9-15
Primum vivere? Le produzioni biologiche fra nuova Pac, esigenze di sostenibilità e sicurezza alimentare
No full textIl saggio intende fornire una prospettiva d’insieme sul futuro del metodo di produzione biologica alla luce dei recenti sviluppi della Pac e della nuova crisi internazionale determinata dalla guerra in Ucraina. Vengono, quindi, in primo luogo passate in rassegna le principali fonti di soft e hard law degli ultimi anni che hanno impresso una notevole spinta all’evoluzione dell’agricoltura europea in chiave “bio”, sottolineando le coerenze delle recenti scelte del legislatore italiano con il quadro complessivo delle indicazioni europee. In secondo luogo, vengono analizzati alcuni dati economici recenti e studi internazionali di impatto circa le conseguenze dell’evoluzione descritta sulla produttività agricola, mettendole in relazione con la nuova interruzione della catena degli approvvigionamenti provocata dalle vicende belliche ucraine e la probabile grave crisi alimentare che si verificherà in autunno. A mo’ di sintesi l’articolo si conclude con alcune considerazioni (necessariamente provvisorie) sulla compatibilità del metodo di agricoltura biologica con le esigenze della sicurezza alimentare, da contemperare, tuttavia, nel breve periodo con alcuni allentamenti del modello per far fronte alle responsabilità internazionali dell’Unione europea in relazione alla crisi umanitaria che deriverà dalla mancata distribuzione sui mercati internazionali del raccolto ucraino di cereali 2021-2022.
This article portraits an overall perspective of the future of organic productions in the light of the recent development of the Cap and the international crisis brought by the war in Ukraine. The Author, first of all, reviews the sources of soft and hard law which have boosted in recent years the organic method in European agriculture, paying specific attention to the Italian legislation. Secondly the article analyses the impact of the European Green Deal approach on the agricultural productivity, matching the results of many different scientific studies with the emerging criticism brought by the war in Ukraine and the food security crisis that – unfortunately – will follow in Autumn. As a result, some final considerations on the persistent compatibility of the organic approach with food security will be set out. The Author considers the organic method fundamental to face the current environmental threats, but some criteria of this model need to be relaxed in the short run in order to face the Ukranian situation and the European international responsibility for food security
Come Il lago dei cigni è diventato Il distaccamento femminile rosso
No full textIl saggio vuole mettere in luce l’importante ruolo culturale della danza in Cina nel Novecento, nel momento del passaggio da impero a nazione, attraverso l’analisi del balletto più rappresentativo della Rivoluzione culturale, Il distaccamento femminile rosso (1964), una delle otto “opere modello” promosse da Mao Zedong in un’ottica di propaganda dell’ideologia comunista.
Partendo dal contesto socio-culturale in cui si è sviluppata questa forma di balletto “rivoluzionario”, ispirato paradossalmente non tanto alla danza libera e moderna occidentale quanto al balletto sovietico, l’autore si interroga sulla centralità che assume la figura femminile e sull’uso del suo corpo rispetto alla tradizione teatrale cinese.This essay aims to highlight the important cultural role of dance in twentieth-century China, when it transformed from empire into a nation. The analysis will focus on one of the most representative ballets of the Cultural Revolution, The Red Detachment of Women (1964), one of the Eight Model Operas promoted by Mao Zedong from the point of view of the communist ideology. Starting from the socio-cultural context in which this sort of “revolutionist” ballet developed, inspired paradoxically to the Soviet ballet instead of the free and modern Western dance, the author discusses the relevant position of the female figure and the use of her body as compared to Chinese theatrical tradition
