Immigrazione e territorio in Abruzzo/Immigration and territory in the Abruzzo region
No full textIl saggio, dopo una breve introduzione che richiama il tema della presenza straniera in Italia, affronta il caso dell’Abruzzo che è passato recentemente da terra di emigranti a regione di immigrazione. Inserito nel contesto geografico centro-orientale della penisola, il fenomeno migratorio rientra qui nel modello d’insediamento a prevalenza balcanica. I primi due gruppi nazionali, albanesi e macedoni, sono concentrati in gran parte nelle aree montane interne e occupati nel settore della pastorizia. Vi è poi una significativa incidenza dei nordafricani e una consistente comunità di senegalesi, dediti soprattutto al commercio ambulante e distribuiti principalmente sul litorale adriatico. Il mondo del lavoro, le necessità abitative, la distribuzione territoriale delle presenze, le dinamiche dell’illegalità e dell’integrazione, il ruolo della società civile e delle istituzioni segnalano l’esistenza di processi trasformativi in una regione in cui un’immigrazione mediamente giovane, ancora quantitativamente modesta e a carattere prevalentemente familiare, tende a divenire sempre più stabile e numerosa.After a brief introduction referring to foreign presence in Italy, this essay deals with the case of Abruzzo, which has recently moved from being a land of migration to a land of immigration. Placed in the central-eastern geographical context of the Italian peninsula, the migration phenomenon is here prevalently of Balkan character. The two prevalent ethnic groups, Albanians and Macedonians, concentrate mainly in the mountain area of the interior and their main activity is as shepherds. There is also a noticeable presence of Northern Africans and a numerous community of Senegalese, mainly engaged in itinerant trade and mainly settled along the Adriatic coast. The world of labour, their needs of habitation, their distribution over the territory, their position respect to illegality and integration, the role of civil society and institutions show the presence of transformation processes in a region in which immigration of a young population on average, still quantitatively moderate and of mainly family character, tends to become increasingly stable and numerous

The action involves three different research fields: star tracker (CCD and APS technologies), IMU (gyroscope and accelerometer MEMS technology) and microprocessor for managing as both “single sensor” and combined operation mode
Variations on the Author
No full text“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

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
Understanding the effects of tunneling on buildings by analyzing DInSAR data: The case of the new subway in Rome, Italy
No full textMonitoring the displacements of the buildings during the execution of underground works is a very demanding activity in large urban areas contexts, due to the number of structures involved and to the duration of the measurements throughout the realization time. Therefore, the surface deformation detection cannot be based on direct measurements using ground-based sensors, only, and should include technologies that allow a systematic and comprehensive monitoring. The satellite DInSAR technique (Differential Interferometry Synthetic Aperture Radar) provides displacement time series of a large number of measuring points, which can be associated with different portions of a building and are able to reveal differential settlements. Furthermore, the availability of SAR data archived since 1992 allows performing back analyses to evaluate also long-term settlement processes not directly linked to the tunneling works. More recently, the COSMO-SkyMed constellation, developed by the Italian Space Agency (ASI), has provided data at higher space/time resolution, which have been profitably used to detect and follow the evolution of the settlements caused by tunneling excavation works, as in the case of the new metro line in Rome. By applying the advanced DInSAR methodology, we have estimated average rates of displacement for a number of buildings over the Metro C track interested by the subsidence, very likely triggered by tunneling. A classification-based approach was applied by taking into account the displacement rates and the associated statistical error parameters. This provided a tool for the direct identification of the most critical buildings that need further investigations
