No full textco-curatela di un volume sulle forme della comunicazione academica in ambito umanistico contenente saggi di studiosi di diverse università italiane
Ideologies underlying new legislative proposals for the naturalization of adult immigrants in Italy
No full textIl contributo, consiste in un’analisi critica dei tipi di conoscenza richiesti dal cosiddetto ‘Testo Unificato Bressa’ per la concessione della cittadinanza italiana ad adulti immigrati. Tale testo, che propone cambiamenti alla legge precedente del 1992, pur migliorandone alcuni aspetti, presenta serie criticità, che vengono qui discusse nel dettaglio. In particolare:
(a) adotta una nozione riduttiva di ‘conoscenza linguistica’,
(b) richiede una conoscenza esclusivamente orale della lingua italiana,
(c) propone un modello di integrazione assimilazionista, basato su una ideologia monolinguistica e monoculturale

No full textLe lingue in classe: Discorso, apprendimento, socializzazione
No full textIl titolo di questo volume, “Le lingue in classe”, fa riferimento all’attuale realtà scolastica italiana, sempre più caratterizzata dal multilinguismo e dal multiculturalismo. Occuparsi delle lingue in classe significa oggi prendere in considerazione una gamma di situazioni di apprendimento/insegnamento linguistico: non soltanto la classe di italiano disciplinare o quella di lingua straniera, ma anche altri contesti educativi in cui lingue e culture diverse vengono a trovarsi a contatto - ad esempio, la classe di italiano lingua seconda, la classe multilingue.
Sullo sfondo della letteratura più aggiornata, il volume esamina fenomeni che caratterizzano i diversi contesti e aspetti che li accommunano in quanto ad essi traversali: modalità discorsive, strutture di partecipazione, processi di socializzazione.
Partendo dal presupposto che la riflessione sulle proprie e sulle altrui pratiche didattiche costituisca uno strumento fondamentale per la formazione e l’aggiornamento, ogni capitolo presenta all’analisi e alla discussione una ricca esemplificazione di interazioni registrate nella scuola materna, elementare e media
On chromatic symmetric homology and planarity of graphs
Full text linkSazdanovic and Yip defined a categorification of Stanley's chromatic function
called the chromatic symmetric homology. In this paper we prove that (as
conjectured by Chandler, Sazdanovic, Stella and Yip), if a graph is
non-planar, then its chromatic symmetric homology in bidegree (1,0) contains
-torsion. Our proof follows a recursive argument based on
Kuratowsky's theorem.Comment: 11 pages. Some changes have been made in Section 3 in order to
improve readability. arXiv admin note: substantial text overlap with

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
HSLTP - An LTP Variant for High Speed Links and Memory Constrained Nodes
Full text linkDelay/disruption-tolerant networking architecture relies on the use of Licklider Transmission Protocol (LTP) on interplanetary links. LTP loss recovery is based on automatic repeat request retransmissions, which, when the propagation delay is very long, are costly. Alternatively, losses could be recovered by using Packet Layer Forward Error Correcting codes, as done by the authors in ECLSA (error Coding Link Service Adapter), recently presented in a companion paper, where LTP segment retransmissions are limited to the unlikely case of decoding failures. However, on high bandwidth-delay-product links, the very possibility of segment retransmission requires that a huge number of Rx buffers be available. To resolve this problem, high-speed LTP, presented here, has a more disruptive approach than ECLSA: it enforces almost one-to-one correspondence between LTP blocks and FEC codewords, and never requires LTP segment retransmissions. In the unlikely case of a FEC failure, the partially received block is discarded and its bundles are resent directly by the bundle protocol. The advantages and disadvantages of this approach are explored in the article. On nodes limited in memory, the results are significantly improved
