La route qui mène au crime : déterminants de la mobilité des infracteurs de Gatineau en 2006

Cette étude porte sur la distance parcourue pour commettre un crime à Gatineau en 2006. Peu d’études canadiennes récentes ont porté sur le sujet. De plus, il existe un vide de connaissances sur la mobilité des délinquants dans les petites villes et les banlieues. La présente recherche vise à comparer trois mesures de distance différentes, à vérifier si la distance parcourue varie en fonction du type de crime et à voir si les variables de temps (jour de la semaine, moment de la journée et saison) de même que certaines caractéristiques des suspects (âge, sexe et lieu de résidence) ont un impact sur la distance parcourue. Pour chaque crime, l’adresse du suspect et le lieu du crime ont été géocodées pour ensuite calculer la distance entre les deux points. Il ressort de l’analyse de la forme des courbes de distances que seules les agressions sexuelles présentent une zone tampon. Les résultats des analyses statistiques indiquent que les jeunes sont plus mobiles que les suspects plus âgés et que les hommes parcourent une distance plus élevée que les femmes. Étonnement, la distance parcourue ne diffère pas significativement selon la saison et le moment de la journée. Enfin, comparativement aux autres criminels, les délinquants qui ont commis un vol qualifié sont ceux qui ont parcouru les plus grandes distances.

Zone d'attente pour personnes en instance : une ethnographie de la détention frontalière en France

L’ethnographie de la détention frontalière en France se penche sur le phénomène des migrations transnationales et sur le gouvernement des frontières qui y répond, à travers des pratiques d’enfermement et d’expulsion des étrangers dans une « zone d’attente » aéroportuaire. La construction des camps d’étrangers, dont relève ce terrain, témoigne de nouvelles distributions du pouvoir qui passent par l’accès à la mobilité. L’étude empirique d’une forme particulière de ce contrôle est ainsi le point de départ d’une réflexion plus large sur ce régime de gouvernement, qui dessine une autre topographie politique de la globalisation. L’enquête nous invite à comprendre les pratiques par lesquelles les gouvernements démocratiques administrent des populations non-citoyennes, et la façon dont ces modalités de prise en charge et de surveillance opèrent une reconfiguration des frontières physiques, morales et politiques. L’ethnographie s’interroge sur l’expérience quotidienne de ceux qui sont les sujets de ces régimes juridiques et humanitaires croisés. Le confinement des étrangers entrecroise plusieurs dimensions, qui organisent la recherche : la construction d’un enfermement humanitaire, et les usages institutionnels et militants de différents régimes de droits qui y sont en jeu; les pratiques de prise en charge de populations identifiées comme vulnérables; les reconfigurations de la frontière à travers de nouvelles formes réticulaires et zonales; et enfin, l’expérience de circulation que dessinent les archipels de surveillance, et les pratiques de gestion différentielle des mobilités dont participent les zones d’attente.

Mobilità metropolitana a Bologna

Abbiamo analizzato compiutamente la conformazione attuale della città di Bologna, individuandone gli elementi caratterizzanti, i punti di forza e le criticità, per riuscire a riconnetterla sia al tessuto del centro storico sia a quello rurale. Il tipo di metodo scelto riprende in parte quello utilizzato nell’analisi delle mappe storiche, lavorando attorno a tre temi fondamentali: spazi aperti, tessuto urbano e viabilità. La consapevolezza profonda della realtà e delle dinamiche presenti ci ha portato ad individuare la soluzione che riteniamo essere più funzionale per la riconnessione delle differenti zone, utilizzando la fascia come filtro tra campagna e città. L’obiettivo individuato è quello di sfruttare la linea ferroviaria in disuso convertendola in una linea di tram-treno, una infrastruttura elettrica e a basso impatto ambientale che funzioni in modo agile e puntuale contribuendo in maniera significativa alla mobilità da e verso il centro storico di Bologna, con fermate nei principali fatti urbani come il complesso fieristico, la nuova sede comunale, il centro di ricerca, il polo universitario, i centri sportivi e commerciali. Parte della stessa linea ferroviaria, in particolare il tratto ovest, verrà riqualificato creando un parco lineare sulla sede della linea stessa, come realizzato a Parigi per la “promenade plantée” o a New York con la “highline”, restituendo ai bolognesi un percorso cittadino che valorizzi la natura, la riflessione ed il benessere. Un collegamento tra diverse aree urbane caratterizzato da un flusso più lento esclusivo dei pedoni e dei ciclisti, che trova una sua continuità naturalistica ad ovest andando a collegarsi al parco fluviale del canale Reno, proseguendo invece ad est parallelamente alla linea di tram-treno, creando una continuità di percorsi ciclo-pedonali che si integrano agli esistenti raggiungendo le zone centrali della città. L’intento è quello di incanalare il flusso non carrabile proveniente dalle aree rurali e dalla tangenziale, anche attraverso parcheggi scambiatori, in un percorso privilegiato, funzionale e naturalistico che permetta di raggiungere il centro storico e anche la zona collinare risalendo lungo il parco fluviale, dando ai fruitori la possibilità di osservare Bologna con più tranquillità e da un punto di vista nuovo.

Determination of particle concentration in the breathing zone for four different types of office ventilation systems

Many factors affect the airflow patterns, thermal comfort, contaminant removal efficiency and indoor air quality at individual workstations in office buildings. In this study, four ventilation systems were used in a test chamber designed to represent an area of a typical office building floor and reproduce the real characteristics of a modern office space. Measurements of particle concentration and thermal parameters (temperature and velocity) were carried out for each of the following types of ventilation systems: a) conventional air distribution system with ceiling supply and return; b) conventional air distribution system with ceiling supply and return near the floor; c) underfloor air distribution system; and d) split system. The measurements aimed to analyse the particle removal efficiency in the breathing zone and the impact of particle concentration on an individual at the workstation. The efficiency of the ventilation system was analysed by measuring particle size and concentration, ventilation effectiveness and the Indoor/Outdoor ratio. Each ventilation system showed different airflow patterns and the efficiency of each ventilation system in the removal of the particles in the breathing zone showed no correlation with particle size and the various methods of analyses used.

Determining the zone of reflection for posterior corneal surface comparison phakometry

Although comparison phakometry has been used by a number of studies to measure posterior corneal shape, these studies have not calculated the size of the posterior corneal zones of reflection they assessed. This paper develops paraxial equations for calculating posterior corneal zones of reflection, based on standard keratometry equations and equivalent mirror theory. For targets used in previous studies, posterior corneal reflection zone sizes were calculated using paraxial equations and using exact ray tracing, assuming spherical and aspheric corneal surfaces. Paraxial methods and exact ray tracing methods give similar estimates for reflection zone sizes less than 2 mm, but for larger zone sizes ray tracing methods should be used.

Effect of clear zone widths on run-off-road crash outcomes

Current guidelines on clear zone selection and roadside hazard management adopt the US approach based on the likelihood of roadside encroachment by drivers. This approach is based on the available research conducted in the 1960s and 70s. Over time, questions have been raised regarding the robustness and applicability of this research in Australasia in 2010 and in the Safe System context. This paper presents a review of the fundamental research relating to selection of clear zones. Results of extensive rural highway statistical data modelling suggest that a significant proportion of run-off-road to the left casualty crashes occurs in clear zones exceeding 13 m. They also show that the risk of run-off-road to the left casualty crashes was 21% lower where clear zones exceeded 8 m when compared with clear zones in the 4 – 8 m range. The paper discusses a possible approach to selection of clear zones based on managing crash outcomes, rather than on the likelihood of roadside encroachment which is the basis for the current practice. It is expected that this approach would encourage selection of clear zones wider than 8 m when the combination of other road features suggests higher than average casualty crash risk.

Review : Surfers Paradise foreshore redevelopment masterplan - urban plaza zone

The Centre for Subtropical Design has prepared this submission to assist the Gold Coast City Council to finalise a plan and detailed design guidelines for the Urban Plaza Zone of Surfers Paradise Foreshore Redevelopment Masterplan which will create a public open space ‘alive’ with the quality appropriate to a place which is both a local centre and an international destination. This review has been informed by the two over-arching values identified as characteristics of a subtropical place and people’s connection to it:  A sense of openness and permeability, and  Engagement with the natural environment. The existing qualities of the foreshore area proposed as the Urban Plaza Zone, reflect these subtropical place values, and are integral to the Surfers Paradise identity:  Seamless visual and spatial access to the beach and sea,  Permeable interface between beach and built zones provided by beach planting and shade to sand by Pandanus,  A shade zone mediating beach and linear promenade, road and commercial zones, enabling a variety of social and visual experiences, on soft and hard finishes, and  A lively, constantly moving shared road and pedestrian way catering for events and day to day activities with visual access to beach and shaded areas. The Centre for Subtropical Design commends the Gold Coast City Council on preparing a plan for a public open space that is a contemporary departure from the adhoc basis of development that has occurred, in that it will make this area more accessible. However, the proposed plan seems to be working too hard in terms of ‘program’. While providing an identifiable interruption in the linear extent of the Foreshore, the lack of continuity of design in terms of both hardscaping (such as perpendicular paving elements) and softscaping (such as tree selections) may contribute to a lack of definition for the entire Foreshore as a place that mediates, along its length, between sea and land. Providing a hard edge to a beach character of soft and planted transitional elements needs to balance the proposed visual and physical barrier with the need for perceived and actual easy access. The Surfers Paradise identity needs strengthening through attention to planting for shade, materials, particularly selection of paving colours, and stronger delineation of the linear nature of the Foreshore. The Urban Plaza zone is an appropriate interruption to the continuous planting, however the link from the commercial zone overtakes the public and beach zone. A more seamless transition from shop to sea, better integration of the roadway and pedestrian zone and improved physical transition from concrete to sand is recommended. Built form solutions must be robust and designed with the subtropical design principles and the Surfers Paradise identity as underpinning parameters for a lasting and memorable public open space.

Zonal chondrocyte subpopulations reacquire zone-specific characteristics during in Vitro redifferentiation

Background: If chondrocytes from the superficial, middle, and deep zones of articular cartilage could maintain or regain their characteristic properties during in vitro culture, it would be feasible to create constructs comprising these distinctive zones. ----- ----- Hypothesis: Zone-specific characteristics of zonal cell populations will disappear during 2-dimensional expansion but will reappear after 3-dimensional redifferentiation, independent of the culture technique used (alginate beads versus pellet culture).----- ----- Study Design: Controlled laboratory study.----- ----- Methods: Equine articular chondrocytes from the 3 zones were expanded in monolayer culture (8 donors) and subsequently redifferentiated in pellet and alginate bead cultures for up to 4 weeks. Glycosaminoglycans and DNA were quantified, along with immunohistochemical assessment of the expression of various zonal markers, including cartilage oligomeric protein (marking cells from the deeper zones) and clusterin (specifically expressed by superficial chondrocytes).----- ----- Results: Cell yield varied between zones, but proliferation rates did not show significant differences. Expression of all evaluated zonal markers was lost during expansion. Compared to the alginate bead cultures, pellet cultures showed a higher amount of glycosaminoglycans produced per DNA after redifferentiation. In contrast to cells in pellet cultures, cells in alginate beads regained zonal differences, as evidenced by zone-specific reappearance of cartilage oligomeric protein and clusterin, as well as significantly higher glycosaminoglycans production by cells from the deep zone compared to the superficial zone.----- ----- Conclusion: Chondrocytes isolated from the 3 zones of equine cartilage can restore their zone-specific matrix expression when cultured in alginate after in vitro expansion.

Theraplay : staying in life's performance zone with play - Homo ludens: Man the player - Homo Cogito: Man the thinker

The paper introduces an update on a therapy originally developed by Jernberg (1979) for the American Head Start Programme for use with children and parents. Theraplay was based on John Bowlby's (1969) attachment theory and was started by Jernberg in Chicago. The present use of theraplay is for young adults to deal with negative mood and mood disorders resulting from stress, anxiety or depression. It is for the sad, lonely, sluggish, miserable or melancholic amongst us as well as the worried well.

Motivation : staying in the achievement zone with personal integrity

This paper was presented at orientation, to a select group of Business Faculty First Year students accepted into the "Corporate Partners in Excellence Programme" (CPIE). It discusses some of the strategies for continuing as high performing students in University studies whilst at the same time maturing into successful, ethical professionals with a social and environmental conscience.

The impact of computers on physical and psychological health: Strategies for staying in the "zone".

At a time when distance learning and flexible delivery of university courses are increasing, spending long hours on computers, working from home or in the laboratory, raises some unique problems for students. The paper presents a theoretical framework for first year students which helps to explain the developmental process that many students find themselves going through during their transitional phase at university. It will introduce the concept taken from sports psychology of "staying in the zone of peak academic performance" in order to accomplish the task of obtaining a degree whilst at the same time ensuring physical and psychological health. Strategies used by therapists to assist students to continue successfully in their course of choice and to achieve desirable outcomes will be discussed.
