Il ladino e i suoi idiomi
No full textIn questo capitolo si illustrano le suddivisioni interne al gruppo ladino. Dopo aver sottolineato la posizione particolare dell’ampezzano (appartenente linguisticamente al gruppo cadorino), si mostra che le restanti varietà sono separate da tre diverse linee di demarcazione che si sovrappongono: una linea di origine altomedievale che corre da nord a sud, dividendo Fassa e Gardena da Badia e Fodom; una da ovest a est, più recente, che isola il ladino settentrionale (valli di Gardena e Badia) dal ladino meridionale; e infine una linea circolare che separa le varietà centrali da quelle periferiche.Nella seconda parte del capitolo sono discusse le differenze fonologiche, morfologiche, sintattiche e lessicali che caratterizzano ogni varietà di valle e anche le parlate locali (di singoli paesi o sezioni vallive), quando queste si distinguono dalle altre varietà locali. Il capitolo si chiude con un riferimento all’applicazione del metodo dialettometrico alla classificazione interna del ladino.This chapter discusses the internal divisions within the Ladin group. After pointing out the special position of Ampezzano (which belongs - from a purely internal linguistic point of view - to the Cadore varieties), I show that the rest of the Ladin area is crossed by three different lines: an older one, running from North to South and dividing Fassa and Gardena from Badia and Fodom. The second and more recent one goes from West to East and groups together Northern Ladin (Gardena and Badia) vs. Southern Ladin. Finally, the third line is circular and puts together the central vs. the peripheral varieties. The second part of the chapter discusses the phonological, morphological, syntactical and lexical properties that are peculiar to each valley, as well as the properties of one or the other subgroup (which may consist of the variety spoken just in one village or in a section of the valley). The chapter concludes with a short discussion of the recent dialectometric approach to the internal classification of Ladin
Sulla diffusione dei termini “mòcheno” e “tamocco” nell’arco alpino orientale: nuovi dati e documenti a supporto del collegamento con il medio alto tedesco “mocke”
No full textIn this paper we reconsider the etymology of the esoetnics "mòcheno", "tamocco" and "much/moch" across the Italian Alps, and provide further evidence for the etymological hypothesis we put forward in Casalicchio/Cognola (2016). Specifically, we show that these words develop from the Middle High German form "mocke" in its meaning of "a clodhopper", which developed the specific meaning "Austrian, German" only in those areas in which the Romance population was in contact with German-speaking peasants
A performance analysis of context transfer protocols for QoS enabled Internet services
No full textIn nowadays wireless networks, mobile users frequently access Internet services that are often based on information concerning the application context and service status. In presence of mobility, the procedure of service handover, may require a restart of the ongoing service, if the necessary context information is not properly transferred to the new point of access. Context transfer procedures introduce additional overheads to handovers possibly affecting the quality of service perceived by mobile users and making handovers very critical. In this paper the need for efficient protocols for transferring service context and profile related information is pointed out with reference to many mobile internet services, and the possible scenarios are differentiated on the basis of the handover triggering mechanisms. A performance model to compare these mechanisms, when context transfer protocols run on top of IPv6 with fast handover, is proposed. Numerical results point out the necessity to adapt the triggering mechanism to the size of the context data
Introduzione al Manuale di linguistica ladina
No full textIl capitolo presenta le finalità e la struttura del Manuale di linguistica ladina. In particolare, si discutono le principali questioni definitorie riguardo al glottonimo ed etnonimo ladino, si giustifica la delimitazione del ladino brissinotirolese, oggetto del Manuale, mediante una combinazione di criteri sia di linguistica interna che esterna, che vengono illustrati singolarmente, e infine si prospettano alcuni desiderata nell’ambito della ricerca scientifica sul ladino.This chapter discusses the aims and the structure of the Manuale di linguistica ladina. It focuses in particular on the main classifying issues about "Ladin" used as language name as well as ethnic defiinition; on the combination of internal and external linguistic criteria used to delimit the Ladin area, which is the object of the Manuale; finally, it deals with some desiderata in the field of the scientific research on Ladin
Scalable Web clusters with static and dynamic contents
No full textCluster systems are leading architectures for building popular Web sites that have to guarantee scalable services when the number of accesses grows exponentially. The most common Web cluster systems consist of replicated back-end and Web servers, and a Web switch that routes client requests among the nodes. In this paper, we propose a new scheduling policy, namely Multi-Class Round Robn (MCRR) , for Web switches operating at layer 7 of the OSI protocol stack. Its goal is to improve load sharing in recent Web clusters that provide multiple services such as static and dynamic information. We demonstrate through a wide set of simulation experiments that other dispatching policies aiming to improve locality in server caches give best results for traditional Web publishing sites providing static information and some simple database searches. On the other hand, when we consider more recent Web sites providing dynamic and secure services, MC-RR is much more effective than state-ofthe -art Web switch policies. The proposed algorithm has the additional benefit of guaranteeing more stable results than those of most dynamic policies whose performance depend on optimal tuning of several parameters, very hard to achieve in highly variable Web systems
Metrics for quantifying interdependencies
No full textThe quantification of interdependencies is a, major challenge when attempting to analyze the behavior of critical infrastructures. This paper presents a taxonomy of interdependency quantification metrics based on their information content, decision support and risk analysis capabilities, and computational costs. The paper also discusses a systematic approach for computing metrics and performance indices that measure the effectiveness of strategies designed to enhance critical infrastructure protection and resilience. A case study is used to illustrate the computation of the metrics and performance indices, and their application to the analysis of critical infrastructure interdependencies
The use of gerunds and infinitives in perceptive constructions
No full textIn this article I compare the use of gerunds with perceptive verbs in Spanish and in Gardenese, a Rhaeto-Romance variety spoken in Northern Italy: perceptive gerunds are used as secondary predicates in Spanish, but as defective TP-complements in Gardenese. Following Rizzi’s (2014) account of parametric variation, I propose that the differences are due to the interplay of three parameters: a [+progressive] feature on Gardenese perception verbs, the pure lexical status of perception verbs in Gardenese and a [+Agreement] feature on Spanish gerunds. The discussion of the parameters involved leads to more general considerations, as a new proposal for the structure of perceptive ECMs in Romance, the confirmation of Folli/Harley’s (2007) analysis of Romance causative constructions and the necessity of both the [+Agreement] and the [+Tense] feature in order to allow nominative non-finite subjects. The comparison with other Romance varieties confirms the role played by this parametric variation in perceptive constructions
Ladinia dolomitica
No full textScopo di questo contributo è offrire una panoramica sull’area che viene usualmente definita “Ladinia dolomitica” e sulla varietà linguistica che vi viene tradizionalmente parlata, il ladino. L'articolo descrive brevemente la storia dell'area e dello sviluppo del ladino, e in seguito descrive le caratteristiche fonologiche, morfologiche, sintattiche e lessicali principali del ladino, che lo distinguono dalle vicine varietà italoromanze. In seguito si illustrano le peculiarità linguistiche dei singoli dialetti ladini, che sono parlati ognuno in una valle diversa delle Dolomiti. L'articolo è fortemente innovativo e originale, perché permette di ascoltare i file audio che esemplificano i tratti linguistici discussi nel testo.This paper describes the area that is usually called "Ladinia dolomitica" , focusing on the language that is spoken in this area, Dolomitic Ladin (traditionally considered as part of Rhaeto-romance). The paper discusses the history of the area and of the development of Ladin, and then it lists the phonological, morphological, syntactic and lexical features of Ladin that make it unique within the varieties of Northern Italy. Subsequently, it describes the peculiarities of the individual Ladin dialects, which are spoken each in a different valley of the Dolomites. This paper is highly innovative and original, because it allows the reader to listen to the audio files that exemplify the features discussed in the text
Public administration workflows re-engineering: an agent-based M&S approach
No full textWorkflows in Public Administration (PA) can be mainly classified as inter-organization processes and cannot be modeled using standard methods such as Petri-nets or WF-Nets, but need new modeling paradigms to describe: i) the structure of the organization; ii) the factors that influence the execution of the workflow and iii) the actors (humans and IT systems) that interact with the workflow, generating the workload. This chapter describes the experience matured by the authors in the design and implementation of an agent-based modeling and simulation framework to support the re-engineering of Public Administration workflows. The project, started in late 2003, faced the challenge of analyze, evaluate the performance and finally re-engineer a Public Administration process of the Presidency of Counseil of Ministers: the IT infrastructure management and the service provisioning process. The project was developed at the Italian Prime Minister Office for Informatics and Telematics headed by the second Author. From the solution initially developed to solve this specific problem we built a general framework to support Public Administration processes re-engineering. This framework, named Wf-Simulator, has been successfully used in real workflow modeling and simulation. The chapter describes the initial project, the Wf-Simulator framework and three real case studies: service provisioning in PA, day hospital surgery admission and blood examination management
