Neighbourhood environment, sitting time and motorised transport in older adults: a cross-sectional study in Hong Kong

OBJECTIVES: Sitting time is a public health concern. This study examined associations of objectively measured neighbourhood environmental attributes with non-transport sitting time and motorised transport in 484 Hong Kong older adults. Neighbourhood attributes encouraging walking may help older adults replace some sitting time at home and on motorised transport with light-to-moderate-intensity activities such as strolling around the neighbourhood or walking to/from neighbourhood destinations. Thus, we hypothesised environmental attributes found to be related to walking would show associations with non-transport sitting time and motorised transport opposite to those seen for walking. DESIGN: Cross-sectional. SETTING: Hong Kong, an ultradense urban environment. PARTICIPANTS: 484 ethnic Chinese Hong Kong residents aged 65+ recruited from membership lists of four Hong Kong Elderly Health Centres representing catchment areas of low and high transport-related walkability stratified by socioeconomic status (response rate: 78%). PRIMARY AND SECONDARY OUTCOME MEASURES: Attributes of participants' neighbourhood environments were assessed by environmental audits, while non-transport sitting time and motorised transport were ascertained using the International Physical Activity Questionnaire-Long Form (Chinese version). RESULTS: Daily non-transport sitting minutes were 283 (SD=128) and motorised transport 23 (SD=28). Prevalence of signs of crime/disorder, streetlights, public facilities (toilets and benches) and pedestrian safety were independently negatively related, and sloping streets positively related, to sitting outcomes. Places of worship in the neighbourhood were predictive of more, and prevalence of public transit points of less, non-transport sitting. Associations of either or both sitting outcomes with prevalence of food/grocery stores and presence of parks were moderated by path obstructions and signs of crime/disorder. CONCLUSIONS: The findings suggest that access to specific destinations and relatively low-cost, minimal impact modifications to the urban form, such as street lighting, public toilets, benches and public transit points, could potentially reduce sitting time and associated negative health outcomes in Hong Kong older adults.

Merely the man in the street: community consultation in the planning of 1920s Melbourne

It is an accepted tenet of planning history that Australia's planning practice in the first half of the 20th century was dominated by experts delivering a package of international planning ideas. Is this story made more    complicated, however by the attitudes of the lay Australian to urban planning at this time? What role have the approaches of planners and planning  bodies played in advising the public of the best routes to take  towards comprehensive and appropriate planning? This paper discusses these  issues with use of examples of the general public's letters to  Melboume's Metropolitan Town Planning Commission (MTPC)( 1923-30) about planning issues in Melbourne; the MTPC's responses; and responsive propaganda generated by prominent Melbourne planner Saxil Tuxen (1885-1975).

CH2 - lighting and physiology

This paper explains the designed performances of the new CH2 building in Melbourne, Australia. CH2 is an environmentally significant project that involves biomimicry of natural systems to produce indoor conditions that are conducive to user comfort, health and productivity. This paper focuses on lighting and  physiology and examines the solutions chosen for artificial and natural lighting and the likely effects these will have on building occupants. The purpose of the paper is to critically comment on the adopted strategy and, cognisance of  contemporary thinking in lighting design, to judge the effectiveness of this aspect of the project with a view to later verification and post-occupancy review. The  paper concludes that CH2 is an exemplar of lighting innovation that provides valuable lessons to designers of office buildings, particularly in the Melbourne CBD.

Wavelet packets for lighting-effects determination

This paper presents a system to determine lighting effiects within face images. The theories of multivariate discriminant analysis and wavelet packets transform are utilised to develop the proposed system. An extensive set of face images of different poses, illuminated from different angles, are used to train the system. The performance of the proposed system is evaluated by conducting experiments on different test sets, and by comparing its results against those of some existing counterparts.

Cecil street studio: improvised community and sustainable practices

It is a little after 7.00pm on a Sunday evening and people are still arriving, slightly hurried as they kick off their shoes before entering the studio. They pay $7.00 and find a seat facing the bare studio floor; white floor against the pink walls. The room seems crowded, although the numbers are not large, and people talk comfortably sitting on the few benches and chairs or on the floor. One of the performers emerges from her conversation amongst the audience to front the group and the babble drops away. “How many of you are new to Conundrum?’ she asks. A few people raise their hands, but many do not. The question is a litmus test for the state of the audience and as a way to bring the novice into the game. “Everything performed here tonight will be completely improvised” she continues. “And tonight on Conundrum we have…” and she rattles off a list of the names of the groups or solo performers who will be performing that evening. Some of the names or groups are different from the last Conundrum one month previously. But two of the groups, State of Flux and 5 Square Metres, have been performing at Conundrum, on the last Sunday of every month, for the last eight years.

The impact of a police crackdown on a street drug scene : evidence from the street

This article documents the impact of a police crackdown on a street heroin market in a suburb of Melbourne, Australia, as perceived by individuals involved in the market. While our data suggest that ‘Operation Clean Heart’ achieved its objective of reducing the visible aspects of this street drug scene, they also imply that the drug market rapidly adapted to its new conditions and that the impact of the operation was essentially superficial and temporary. In addition, we contend that the operation had numerous (unintended) negative consequences, some of which are potentially harmful to public health. Negative outcomes implied by our data included the partial displacement of the drug scene to nearby metropolitan areas; the discouragement of safe injecting practice and safe needle and syringe disposal; and more frequent occurrences of violence and fraud. These outcomes may outweigh the perceived positive impacts, which were achieved at significant public expense. We conclude that police crackdowns are inappropriate responses to illicit drug problems; instead, in line with longstanding Australian policy, approaches which incorporate and balance demand reduction, supply reduction and harm reduction principles should be followed.

Evaluation of Flora Fit street : a community-based living initiative. Final report

This report is an evaluation of Flora Fit Street (FFS) based in Clapham Park London. FFS was launched in June 2004 as a 12 month public private partnership between Flora and Clapham Park New Deal for Communities (NDC). Its purpose was to improve the local community’s heart health by
providing a whole range of activities, information and events that focused on increasing physical activity, improving nutrition and smoking cessation.
