Sic transit – la socialité itinérante des centres commerciaux

C’est en supposant l’existence de la richesse interactionnelle des espaces publics que nous analysons, dans cet article, les flux de circulation contemporains des centres commerciaux comme étant l’expression d’une certaine socialité. Bien loin d’être un phénomène propre d’une foule amorphe ou un simple procédé de déplacements individuels, ces marches montrent un besoin de grégarité assumant une forme nomade ou itinérante. Nous soutenons que les centres commerciaux rendent actuels une structure anthropologique faisant de l’agrégation autour de l’espace une base pour la socialité. Ce qui distingue la socialité itinérante est la traversée de l’espace et de la matérialité physique dans le seul but de la transcender. Bien plus que simplement consommer ou se déplacer fonctionnellement, ces flux semblent répondre à l’exigence, face à une austérité urbaine, des formes communautaires du lien social.

Motivating the use of public transit through a mobile glanceable display

With increasing concerns about the impact of global warming on human life, policy makers around the world and researchers have sought for technological solutions that have the potential to attenuate this process. This thesis describes the design and evaluation of an information appliance that aims to increase the use of public transportation. We developed a mobile glanceable display that, being aware of the user’s transportation routines, provides awareness cues about bus arrival time, grounded upon the vision of Ambient Intelligence. We present the design process we followed, from ideation to building a prototype and conducting a field study, and conclude with a set of guidelines for the design of relevant personal information systems. More specifically we seek to test the following hypotheses: 1) That the tangible prototype that provides ambient cues will be used more frequently than a similar purpose mobile app, 2) That the tangible prototype will reduce the waiting time at the bus stop, 3) That the tangible prototype will result to reduced anxiety on passengers, 4) That the tangible prototype will result to an increase in the perceived reliability of the transit service, 5) That the tangible prototype will enhance users’ efficiency in reading the bus schedules and 6) That the tangible prototype will make individuals more likely to use public transit. In a field study, we compare the tangible prototype against the mobile app and a control condition where participants were given no external support in obtaining bus arrival information, other than their existing routines. Using qualitative and quantitative data, we test the aforementioned hypotheses and explore users’ reactions to the prototype we developed.

Diverticulosis y relación con el consumo de fibra en pacientes del Hospital Universitario de la Samaritana

Introducción: La diverticulosis es la condición más frecuentemente encontrada en la colonoscopia, condición asintomática, con un alto costo para el sistema de salud. Diversos factores han demostrado estar en relación con la aparición de la enfermedad. En nuestra población, esta información se desconoce; el objetivo del estudio es la caracterización de la población con diverticulosis y su relación con la frecuencia de la ingesta de fibra. Materiales y Métodos: Estudio observacional prospectivo de corte transversal con componente analítico. Realizado a todas las personas que asistieron al HUS a realización de colonoscopia entre Noviembre de 2015 y Abril de 2016. Se recolectaron datos de la frecuencia de fibra ingerida a través de entrevistas basadas. Resultados: Se estudiaron 278 personas, 55.7% mujeres. La prevalencia de diverticulosis fue de 21.58%, siendo más frecuente en mujeres ( 66,7%), 31% entre los 71-80 años, 2,16% tenían antecedente familiar de diverticulosis; principal sitio de afectación fue colon sigmoide en las mujeres y el colon descendente en los hombres. En las personas con diverticulosis el consumo de harina de trigo fue mayor (91,67% vs 86,7%), mientras el consumo de frutas fue mayor en las personas que no presentaron diverticulosis (83,49% vs 78,33%). Conclusiones: La prevalencia de diverticulosis es similar a lo reportado en la literatura. Así mismo se encontró un mayor consumo de fibra en la población sin divertículos lo que hace pensar que a pesar de que esta condición es multifactorial , el consumo de mayores cantidades de fibra puede prevenir la aparición de la misma

A qualitative study of the career aspirations of resettled young Sudanese and Somali refugees

The study documents and explicates the academic experiences, visions, hopes and desires which shape the vocational aspirations of young Sudanese and a Somali refugee who have resettled in Australia. Semi-structured interviews were conducted to examine the experiences of a sample of 14 young resettled refugees in Brisbane, Australia. Adopting a qualitative methodology, the interviews covered the aspirations of the participants across three time periods: life in the country of origin, transit and resettlement. Participants expressed high ambitions despite their experiences of school disruption pre resettlement and language difficulties post resettlement. The situation in the country of origin emerged as influential upon their aspirations in both pre and resettlement life. English language difficulties emerged as the most common consideration influencing aspirations following resettlement. A number of considerations were found that influenced their vocational aspirations before and after resettlement. Such considerations may enlighten service providers working with resettled young African refugees.

Effects of fare collection policy on operating characteristics of a Brisbane busway station

Transit agencies across the world are increasingly shifting their fare collection mechanisms towards fully automated systems like the smart card. One of the objectives in implementing such a system is to reduce the boarding time per passenger and hence reduce the overall dwell time for the buses at the bus stops/bus rapid transit (BRT) stations. TransLink, the transit authority responsible for public transport management in South East Queensland, has introduced ‘GoCard’ technology using the Cubic platform for fare collection on its public transport system. In addition to this, three inner city BRT stations on South East Busway spine are operating as pre-paid platforms during evening peak time. This paper evaluates the effects of these multiple policy measures on operation of study busway station. The comparison between pre and post policy scenarios suggests that though boarding time per passenger has decreased, while the alighting time per passenger has increased slightly. However, there is a substantial reduction in operating efficiency was observed at the station.

Non-motorized public transport development : present scenario and future approach in developing cities

Over the last few decades, most large cities in the developing world have been experiencing rapid and imbalanced transport sector development resulting in severe congestion and poor levels of service. The most common response at a policy level under this circumstance has been to focus on private and public motorized transport modes, and especially on traffic control measures and mass transit systems. Despite their major role in the overall transport system in many developing cities in Asia & Latin America, relatively little attention is given to non-motorized transport (NMT) modes (walk, bicycle and cycle-rickshaw). In particular, this ideology is applicable to the paid category of non-motorized public transport (NMPT), notably three-wheeler cycle rickshaws that still have an important socio-economic, environmental and trip-making role in many developing cities. Despite, they are often seen as inefficient and backward; an impediment to progress; and inconsistent with modern urban image. Policy measures therefore, to restrict or eliminate non-motorized transport from urban arterials and other feeder networks have been implemented in cities as diverse as Dhaka, Delhi, Karachi, Bangkok, Jakarta, Manila, Surabaya and Beijing . This paper will primarily investigate the key contribution of NMPT in the sustainable transport system and urban fabric of developing cities, with Dhaka as case study. The paper will also highlight in detail the impediments towards NMPT development and provide introductory concept on possible role this mode is expected to play into the future of these cities

AITPM Email Newsletter Volume 0907, July 2009 : President's Message

President’s Message AITPM President’s Message, July 2009 Hello fellow AITPM members, It’s now very early July so many Australians are going to experience a range of new, or increases in, fees, charges, and perhaps taxes by State and local governments. For example, Queenslanders are to be hit at the petrol pump, no longer living with the luxury of the State’s previous 8c per litre fuel subsidy, bringing general motorists’ fuel costs into line with the other States. A consolation is that they now don’t have to live with the real or perceived “price gouging” that has appeared in the past to make Queensland prices much closer than 8c to those in other States. Environmental lobbyists argue that this Government’s decision brings public transport costs closer to parity with private transport. However, my sense from sloppy petrol price elasticities is that the State’s motorists will get used to the reversal of what was a reverse tax pretty quickly, an amount which can be less than day-of-the week fluctuation. On the other hand, withholding this State revenue may help in some way the funding of the several major public transport infrastructure projects in progress; not to mention some of the cost of running the Transit Authority’s expanding service commitments. Other policy actions, such as a Federal Government review of taxation on employees’ package vehicles, which might discourage rather than encourage excess kilometres travelled, may have a greater environmental benefit. Of course, a downside is that many vehicles used so are Australian built, and discouraging fleet turnover may damage an industry which faces ever increasing uncertainty, and particularly at the present, is in need of some care and attention. I for one hope to this end that the new 4 cylinder (1.8L petrol or 2L diesel) so called “true Holden” Cruze and Toyota’s pending Camry Hybrid are both roaring successes, and will be taken up in droves as fleet and employee use vehicles. I’m not sure what drive-trains Ford and Holden plan to drop into their next full sized models but even if they’re not Australian sourced, let’s hope they coordinate the requisite performance expected by the “Aussie Battler” with suitable green credentials. I am also encouraged to see that already many Government fleet vehicles are smaller in size, but still fit for purpose. For instance, my local police station uses the Camry based Aurion as a district car. I close again in reminding everyone that AITPM’s flagship event, the 2009 AITPM National Conference, Traffic Beyond Tomorrow, is being held in Adelaide from 5 to 7 August. www.aitpm.com has all of the details about how to register, sponsor a booth, session, etc. Best regards all, Jon Bunker

Members abroad - Australia : Paul Sanders

I have been an academic since joining the University of Natal in 1998 and, following a period as a visiting lecturer in Brisbane in 2001, I joined the staff at QUT on an ongoing basis in 2003. I was appointed as Architecture Co-ordinator in 2006, and this role involves the leadership of the architectur discipline of 17 full time academics. I am currently enrolled in a PhD course in the field of urban morphology. This research proposes a theory on the relevance of mapping the evolutionary aspects of historical urban form to develop a measure for evaluating architecural elements and deriving parameters for new buildings. My participation in a QUT design team contributed to a recent successful invited competition bid for an Urban Transit Centre in Hangzhou, China. The Centre will include retail, business, entertainment, residential and service components at the heart of the Binjiang district on the 11.5ha core area with 32ha surrounding urban design precinct. The project has received the approval to commence and is to be implemented over the next three years!

The application of the Park & Ride and TOD concepts to develop a new framework that can maximise public transport patronage

With growing concern over the use of the car in our urbanized society, there have emerged a number of lobby groups and professional bodies promoting a return to public transport, walking and cycling, with the urban village as the key driving land use, as a means of making our cities’ transportation systems more sustainable. This research has aimed at developing a framework applicable to the Australian setting that can facilitate increased passenger patronage of rail based urban transport systems from adjacent or associated land uses. The framework specifically tested the application of the Park & Ride and Transit Oriented Development (TOD) concepts and their applicability within the cultural, institutional, political and transit operational characteristics of Australian society. The researcher found that, although the application of the TOD concept had been limited to small pockets of town houses and mixed use developments around stations, the development industry and emerging groups within the community are posed to embrace the concept and bring with it increased rail patronage. The lack of a clear commitment to infrastructure and supporting land uses is a major barrier to the implementation of TODs. The research findings demonstrated significant scope for the size of a TOD to expand to a much greater radius of activity from the public transport interchange, than the commonly quoted 400 to 600 meters, thus incorporating many more residents and potential patrons. The provision of Park & Rides, and associated support facilities like Kiss & Rides, have followed worldwide trends of high patronage demands from the middle and outer car dependent suburbs of our cities. The data collection and analysis gathered by the researcher demonstrated that in many cases Park & Rides should form part of a TOD to ensure ease of access to rail stations by all modes and patron types. The question, however, remains how best to plan the incorporation of a Park & Ride within a TOD and still maintain those features that attract and promote TODs as a living entity.

Binjiang urban centre and transport interchange

This project is the result of a collaborative design process involving QUT School of Design, and AREN Consulting and ZIAD (Zheijiang Provincial Institute of Architectural Design and Research). This major urban initiative explores new standards for multi-function urban centres. The sophisticated integration of transit interchange with retail, commercial and residential functions provides a dramatic mix of social activities. The large site is formed into a raised and terraced urban garden, with the transit centre and retail shopping precinct housed below this landscaped roof. Towering above this ‘hill’ are five building blocks housing the commercial and residential accommodations. These environmentally low-impact buildings are topped with a high-tech greenhouse roof or photovoltaic cells.

Future developments in chest pain diagnosis and management

Much of the focus of research on patients with chest pain is directed at technological advances in the diagnosis and management of acute coronary syndrome (ACS), pulmonary embolism (PE), and acute aortic dissection (AAD), despite there being no significant difference at 4 years as regards mortality, ongoing chest pain, and quality of life between patients presenting to the emergency department with noncardiac chest pain and those with cardiac chest pain. This article examines future developments in the diagnosis and management of patients with suspected ACS, PE, AAD, gastrointestinal disease, and musculoskeletal chest pain.

Latent variable models in statistical genetics

Understanding the complexities that are involved in the genetics of multifactorial diseases is still a monumental task. In addition to environmental factors that can influence the risk of disease, there is also a number of other complicating factors. Genetic variants associated with age of disease onset may be different from those variants associated with overall risk of disease, and variants may be located in positions that are not consistent with the traditional protein coding genetic paradigm. Latent Variable Models are well suited for the analysis of genetic data. A latent variable is one that we do not directly observe, but which is believed to exist or is included for computational or analytic convenience in a model. This thesis presents a mixture of methodological developments utilising latent variables, and results from case studies in genetic epidemiology and comparative genomics. Epidemiological studies have identified a number of environmental risk factors for appendicitis, but the disease aetiology of this oft thought useless vestige remains largely a mystery. The effects of smoking on other gastrointestinal disorders are well documented, and in light of this, the thesis investigates the association between smoking and appendicitis through the use of latent variables. By utilising data from a large Australian twin study questionnaire as both cohort and case-control, evidence is found for the association between tobacco smoking and appendicitis. Twin and family studies have also found evidence for the role of heredity in the risk of appendicitis. Results from previous studies are extended here to estimate the heritability of age-at-onset and account for the eect of smoking. This thesis presents a novel approach for performing a genome-wide variance components linkage analysis on transformed residuals from a Cox regression. This method finds evidence for a dierent subset of genes responsible for variation in age at onset than those associated with overall risk of appendicitis. Motivated by increasing evidence of functional activity in regions of the genome once thought of as evolutionary graveyards, this thesis develops a generalisation to the Bayesian multiple changepoint model on aligned DNA sequences for more than two species. This sensitive technique is applied to evaluating the distributions of evolutionary rates, with the finding that they are much more complex than previously apparent. We show strong evidence for at least 9 well-resolved evolutionary rate classes in an alignment of four Drosophila species and at least 7 classes in an alignment of four mammals, including human. A pattern of enrichment and depletion of genic regions in the profiled segments suggests they are functionally significant, and most likely consist of various functional classes. Furthermore, a method of incorporating alignment characteristics representative of function such as GC content and type of mutation into the segmentation model is developed within this thesis. Evidence of fine-structured segmental variation is presented.

Empirical derivation and validation of a wandering typology

OBJECTIVES: To develop and validate a wandering typology. ---------- DESIGN: Cross-sectional, correlational descriptive design. ---------- SETTING:: Twenty-two nursing homes and six assisted living facilities. ---------- PARTICIPANTS: One hundred forty-two residents with dementia who spoke English, met Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for dementia, scored less than 24 on the Mini-Mental State Examination (MMSE), were ambulatory (with or without assistive device), and maintained a stable regime of psychotropic medications were studied. ---------- MEASUREMENTS: Data on wandering were collected using direct observations, plotted serially according to rate and duration to yield 21 parameters, and reduced through factor analysis to four components: high rate, high duration, low to moderate rate and duration, and time of day. Other measures included the MMSE, Minimum Data Set 2.0 mobility items, Cumulative Illness Rating Scale—Geriatric, and tympanic body temperature readings. ---------- RESULTS: Three groups of wanderers were identified through cluster analysis: classic, moderate, and subclinical. MMSE, mobility, and cardiac and upper and lower gastrointestinal problems differed between groups of wanderers and in comparison with nonwanderers. ---------- CONCLUSION: Results have implications for improving identification of wanderers and treatment of possible contributing factors.
