Non-Blocking Signature of very large SOAP Messages

Data transfer and staging services are common components in Grid-based, or more generally, in service-oriented applications. Security mechanisms play a central role in such services, especially when they are deployed in sensitive application fields like e-health. The adoption of WS-Security and related standards to SOAP-based transfer services is, however, problematic as a straightforward adoption of SOAP with MTOM introduces considerable inefficiencies in the signature generation process when large data sets are involved. This paper proposes a non-blocking, signature generation approach enabling a stream-like processing with considerable performance enhancements.Comment: 13 pages, 5 figure

THE GULF OF TRIESTE AND ITS BOUNDARIES

Nel caso dei confini sul mare, è difficile immaginare una definizione, delimitazione o demarcazione, così come avviene in terra. La cartografia dimostra di essere un valido strumento di visualizzazione e analisi per il delicato argomento dei confini del mare e delle sue forme di governo, che dettano legge sugli usi e sulle risorse presenti. Si propone di analizzare le varie e sofferte dinamiche dei confini marittimi del Golfo di Trieste attraverso l’utilizzo di cartografia tradizionale e digitale.About maritime boundaries, it is difficult to image a definition, delimitation or demarcation, as it happen as in the land. The cartography proves to be a real tool of showing and analysis for the delicate argument of the sea boundaries and its government shape, wich lay down the law about present uses and resources. This work aims to analyse various and suffered dynamicses about maritime boundaries of the Gulf of Trieste through the use of traditional and digital cartography

Single prazosin infusion in prelimbic cortex Fosters extinction of amphetamine-induced conditioned place preference

Exposure to drug-associated cues to induce extinction is a useful strategy to contrast cue-induced drug seeking. Norepinephrine (NE) transmission in medial prefrontal cortex has a role in the acquisition and extinction of conditioned place preference induced by amphetamine. We have reported recently that NE in prelimbic cortex delays extinction of amphetamine-induced conditioned place preference (CPP). A potential involvement of α1-adrenergic receptors in the extinction of appetitive conditioned response has been also suggested, although their role in prelimbic cortex has not been yet fully investigated. Here, we investigated the effects of the α1-adrenergic receptor antagonist prazosin infusion in the prelimbic cortex of C57BL/6J mice on expression and extinction of amphetamine-induced CPP. Acute prelimbic prazosin did not affect expression of amphetamine-induced CPP on the day of infusion, while in subsequent days it produced a clear-cut advance of extinction of preference for the compartment previously paired with amphetamine (Conditioned stimulus, CS). Moreover, prazosin-treated mice that had extinguished CS preference showed increased mRNA expression of brain-derived neurotrophic factor (BDNF) and post-synaptic density 95 (PSD-95) in the nucleus accumbens shell or core, respectively, thus suggesting that prelimbic α1-adrenergic receptor blockade triggers neural adaptations in subcortical areas that could contribute to the extinction of cue-induced drug-seeking behavior. These results show that the pharmacological blockade of α1-adrenergic receptors in prelimbic cortex by a single infusion is able to induce extinction of amphetamine-induced CPP long before control (vehicle) animals, an effect depending on contingent exposure to retrieval, since if infused far from or after reactivation it did not affect preference. Moreover, they suggest strongly that the behavioral effects depend on post-treatment neuroplasticity changes in corticolimbic network, triggered by a possible “priming” effect of prazosin, and point to a potential therapeutic power of the antagonist for maladaptive memories

Intangible Cultural Heritage Beyond Borders: Egyptian Bellydance (Raqs Sharqi) as a Form of Transcultural Heritage

The 2003 UNESCO Convention on Intangible Cultural Heritage highlights the importance of safeguarding traditional practices. While some of these practices are only performed in their place of origin, others (such as yoga and flamenco) take place worldwide. In this paper we explore what happens when a form of ICH that originated in one place becomes global. For this, we use Egyptian raqs sharqi (bellydance) as a case study. This is a dance genre with strong cultural roots in Egypt but is also hybrid and now practiced worldwide. Theoretically, we draw on a holistic view of living heritage, Welsch's transculturality and Urry's mobilities. Research methods include one-to-one interviews, analysis of written sources and of online dance videos. Raqs sharqi emerges as hybrid and transcultural, yet strongly connected to Egypt as the origin of its heritage. We conclude that ICH can be transcultural and global, whilst maintaining a strong connection to its place of origin

Returns to Foreign and Host Country Qualifications: Evidence from the US on the Labour Market Placement of Migrants and the Second Generation

The integration of migrants in the US economic system is a central concern of policy-makers and scholars. A faster and smoother assimilation of valuable human capital would indeed benefit the labour market, increasing its efficiency. To investigate the integration of minorities and migrants in the US labour market, we employ data from the Current Population Survey from June 2016 (the primary source of labour force statistics in the US). We focus on the following ethnic groups: White, Black, Asian, and Other (a combination of Native Americans, Pacific and Mixed). For each ethnicity we consider if respondents are US born, 1st- or 2nd-generation of immigrant descent. Among 1st-generation migrants, we further differentiate between recent (in the country for 10 years or less) and long (in the country for more than 10 years) arrivals, as they are likely to have different levels of social capital and knowledge of the job market. We focus on three very relevant labour market outcomes: being employed, being employed in a public sector job and working in a professional or managerial position. Our results indicate better placement of individuals with tertiary degrees, an effect particularly important among women. Minorities in the public sector have made some important gains in terms of occupational attainment parity with the white majority
