Memoria del progetto - Progetto della memoria. Udine. Archivi. Pratiche edilizie
No full textA partire dalla ricerca condotta sull’Archivio dell’edilizia privata del Comune di Udine, il volume è suddiviso in tre parti.
1/ “Udine – Città memoria progetto”, che propone una serie di interventi volti da un lato a fornire un quadro della cultura architettonica cittadina dall'Ottocento ai giorni nostri, dall’altro a compiere una più ampia ricognizione sulle fonti archivistiche pubbliche e private inerenti la storia urbana e l’architettura udinesi.
2/” Un archivio per la città. L’edilizia privata a Udine fra Otto e Novecento”, in cui i partecipanti al gruppo di ricerca sull’Archivio comunale dell’edilizia privata intervengono individualmente con contributi di analisi e, collettivamente, per esemplificarne i contenuti attraverso un percorso tematico e per immagini.
3/ “Fonti documentarie e sistemi informativi per l’architettura”. In riferimento al problema dell'utilizzo e della gestione delle fonti archivistiche concernenti l'assetto urbano e l'architettura, gli interventi proposti in questo capitolo presentano esperienze riferite a vari contesti e realtà nazionali
Raised crosswalks and their design features in traffic calming
Full text linkA road hump, or speed hump, is a traffic calming device used to reduce vehicle speed and volume on residential streets. Road humps are placed across the road to slow traffic and are often installed in a series of several humps in order to prevent cars from speeding before and after the hump. Speed humps are used in locations where very low speeds are desired and reasonable. Speed humps are typically placed on residential roads and are not used on major roads, bus routes, or primary emergency response routes. In Italy, the road humps are often built in shape of raised crosswalks, or RCWs, and they are generally placed both close and between intersections.
This paper deals with the analysis of observed data on a large sample of RCWs located in Tuscany, central Italy. Such data were referred both to geometry characteristics of the single raised crosswalk and recorded differences in vehicle speeds before and after it. Speed data were gathered using two automatic radar-recorders for each one of the sampled raised crosswalks.
All the collected data were analyzed trough statistical tests in order to assess their homogeneity or not between different locations and various types of roads. Finally, we were able of making some conclusions and highlighting design aspects. On one side, RCWs with similar geometries and higher heights (about 15 cm) have similar effects on vehicle speeds lowering, regardless of local conditions (location, road geometry, driver behaviour, etc.).
Moreover, raised crosswalks installed in a series have strong efficacy than the isolated ones. On the opposite side, the effects of raised crosswalks with smaller heights (less than 6 cm) show clearly a very low influence on vehicle speed variations
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
