Hidden selectivity: irregular migrants and access to socio-health services in a heated local context
Get PDFIrregular migrations and access to social and health services by undocumented migrants has
become a very relevant issue in the Italian public discussion about migration policies in the last years.
On one hand, the criminalisation of irregular migration has been feeding xenophobic policies; on the
other hand, the regional law on immigration in the Region of Tuscany has been trying to put forward
an alternative model. By declaring the right of irregular migrants to access basic socio-health services,
the Region of Tuscany enacted a radical opposition to the National Immigration Law. In such a context,
what happens when irregular migrants meet public services, and in particular, social and health services,
in a local area characterised by a significant number of migrants? The following reflections deal with
the municipality of Prato: since the end of the 1980s, this city has become the settlement area of a
high number of migrants coming from many different countries. The paper underlines both the lack of
efficacy of policies merely inspired to repressive goals and the very influential role played by operators
within the public sector and non-profit associations in dealing with ambiguous, informal, and unclear
domains of intervention. In a context marked by a growing disengagement of the public sector toward
marginal and vulnerable people (like, in many cases, irregular migrants), the time has come to impose
a new commitment for the public sector and draw a different way of considering the needs of irregular migrants

Cloud standards: Security and interoperability issues
No full textIn the last years, the surging demand for inexpensive and scalable IT infrastructures led to the widespread adoption of Cloud computing architectures; nowadays, Cloud architectures have reached their momentum due to their inherent capacity of simplifying IT infrastructure building and maintenance by making related costs easily accountable and paid on a pay-per-use basis.
Although a general agreement about standards has still to be reached, some emerging de-facto definitions, such as the one proposed by the National Institute of Standards and Technology (NIST) underline that Cloud computing inherits from several state-of-the-art technologies, including grid computing, virtualization, Service Oriented Architectures (SOA), and utility computing. At the same time, to make the process more complex, at the current stage, Cloud providers work at the different Cloud software stack layers, namely, Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) and they tend to adopt proprietary Cloud solutions and middleware platforms, thus producing isolated environments with many risks stemming from that isolation that can hardly obstruct further advancements of Cloud computing. This lack of proper Cloud standardization and certification processes, especially for security-related aspects, hinders the outsourcing of enterprise IT assets to third-party Cloud computing platforms because organizations are afraid of the loss of control over their Cloud-hosted assets and feel very hard and difficult to migrate from one Cloud solution to another one.
Starting from the core assumption that only a deep and broad knowledge of existing efforts can pave the way to the publication of widely-accepted future Cloud standards, this chapter aims at putting together current trends and open issues in Cloud standardization to derive an original and holistic view of the existing proposals and specifications. In particular, among the several Cloud technical areas, our analysis focuses on two main aspects, namely, security and interoperability, because they are the ones mostly covered by ongoing standardization efforts and, from both our experience and existing studies about enterprise concerns and acceptance of Cloud technologies, currently represent two of the main limiting factors for the diffusion and large adoption of Cloud. After an in-depth presentation of security and interoperability requirements and standardization issues, we overview main general frameworks and initiatives in these two areas, and then we introduce and survey all main related standards; finally, we compare surveyed standards and give future standardization directions for Cloud

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
