Understanding trends and drivers of urban poverty in American cities
2022
Urban poverty arises from the uneven distribution of poor populations across neighborhoods of a city. We study the trend and drivers of urban poverty across American cities over the last 40 years. To do so, we resort to a family of urban poverty indices that account for features of incidence, distribution, and segregation of poverty across census tracts. Compared to the universally-adopted concentrated poverty index, these measures have a solid normative background. We use tract-level data to assess the extent to which demographics, housing, education, employment, and income distribution affect levels and changes in urban poverty. A decomposition study allows to single out the effect of cha…
FISSIT (Fistula Surgery in Italy) study: A retrospective survey on the surgical management of anal fistulas in Italy over the last 15 years
2021
Background: Surgical treatment of anal fistulas is still a challenge. The aims of this study were to evaluate the adoption and healing rates for the different surgical techniques used in Italy over the past 15 years. Methods: This was a multicenter retrospective observational study of patients affected by simple and complex anal fistulas of cryptoglandular origin who were surgically treated in the period 2003–2017. Surgical techniques were grouped as sphincter-cutting or sphincter-sparing and as technology-assisted or techno-free. All patients included in the study were followed for at least 12 months. Results: A total of 9,536 patients (5,520 simple; 4,016 complex fistulas) entered the stu…
Laser-evoked potentials for assessment of nociceptive pathways in humans
1998
I n their Focus article, Chen, Arendt-Nielsen, and Plaghki [8] provide a comprehensive review of the . literature o~ human evoked potentials that ~re elicited by noxious heat, usually generated by Infrared laser stimulators. From this review, we identified four issues that may deserve a comment: (1) Standardize the experiment or its scientific report? (2) Nociception and pain. (3) What do laser-evoked potentials (LEPs) really measure? (4) Rational clinical use. For the sake of brevity, we do not attempt to quote all relevant literature; a complete literature survey can be found in a recent review paper by Bromm and Lorenz [4].
Autologous conditioned serum for chronic pain in patients with osteoarthritis: A feasibility observational study
2022
Background Autologous conditioned serum is a product of blood origin, with fragmented evidence of therapeutic properties in osteoarthritis chronic pain. This pilot observational prospective study aimed to evaluate the feasibility of a treatment with conditional autologous serum (ACS) in patients with severe chronic pain and grade I-III osteoarthritis and to describe its cytokine content. Methods We prospectively collected data on consecutive patients affected by osteoarthritis grade I to III and treated with four weekly injections of ACS at our outpatient pain service. The primary outcome was pain intensity, measured with the visual analogic scale (VAS). Additional outcomes were symptoms ev…
Identification des compétences à l'école élémentaire :une approche empirique à partir des évaluations institutionnelles
2007
Cet article propose une analyse des résultats des élèves aux évaluations nationales, l’objectif étant de mieux comprendre comment les acquisitions se structurent à l’école primaire. L’intérêt de cette démarche réside principalement dans l’identification de compétences dont la maîtrise est essentielle à la réussite scolaire. L’approche choisie pour traiter la question est résolument empirique et se base sur l’examen des relations statistiques entre les items. Elle permet de répondre à plusieurs questions susceptibles d’intéresser les chercheurs en éducation, mais aussi les acteurs engagés, à différents degrés, dans le pilotage et la gestion pédagogique de l’enseignement primaire. Les évaluat…
The ‘Archaeological Map of Lilybaeum’
2021
The ‘Archaeological Map of Lilybaeum’ is the result of the long-standing scientific cooperation in Marsala between Palermo and Hamburg Universities. This paper investigates the various methods of field research used to gather the necessary data for the archaeological map of ancient Lilybaeum. There will be a particular focus on the topographic survey and photogrammetric aerial survey by Remotely Piloted Aircraft System (RPAS) conducted in the years 2017–2019. The aim of the work is to highlight the impact of the results on already existing research hypotheses and the ways in which the resulting map enhances our knowledge of the ancient city of Lilybaeum.
GIS and Survey in the Archaeological and Landscape Park of Agrigento
2017
Si espongono in maniera sintetica la metodologia e i risultati della prospezione archeologica condotta nell'area del Parco archeologico e paesaggistico di Agrigento. I dati raccolti con il survey e con l'esame delle riprese aeree storiche e attuali e di riprese satellitari sono confluiti in un Sistema Informativo Territoriale, che permetterà la gestione attiva delle aree archeologiche comprese nel Parco. Il sistema inoltre permetterà di comprendere meglio il rapporto insediativo, culturale e simbolico tra la colonia greca e il territorio suburbano. The methodology and the results of the archaeological survey carried out in the area of the Archaeological and Landscape Park of Agrigento are…
Archaeological Survey in Italy between Ancient Topography and Landscape Archaeology
2017
Si riesamina il dibattito, talvolta conflittuale, che negli ultimi decenni ha contrapposto i fautori dell’archeologia dei paesaggi di derivazione anglosassone dai sostenitori della tradizione italiana della topografia antica. Si rileva come alcuni dei presupposti metodologici della topografia antica non erano in contraddizione con le istanze portate avanti dagli archeologi del paesaggio, pur riconoscendosi che topografia antica e archeologia del paesaggio si basano su premesse e approcci differenti e che quest’ultima ha contribuito decisamente alla innovazione metodologica sul campo e al riconoscimento che il paesaggio attuale è il risultato della stratificazione delle attività umane nel co…
Prospecciones sistemáticas en la Depressió de L’Alcoi (Alacant): analizando las colecciones superficiales
2015
En el siguiente texto se presentan los resultados procedentes de las prospec- ciones llevadas a cabo en el valle medio del río Serpis (Alacant, España) durante la últimas década del siglo XX. Éstas siguen la estrategia donde la organización de las colecciones no sigue el concepto de yacimiento. Por otra parte se presentan las ventajas de la utilización de los Sistemas de Posicionamiento Global (GPS) y los Sistemas de Información Geográfica (SIG) como mecanismo básico no sólo para el tratamiento de las colecciones arqueológi- cas sino también para la actualización de los datos documentados durante las prospeccio- nes llevadas a cabo durante los años 80 y principios de los 90. …
