The streets of Iraq : protests, the public sphere and democracy

Since the invasion of Iraq by Coalition forces in 2003, much attention has been paid to the violence ravaging Iraq’s streets, so much so that they have become synonymous with bloodshed and chaos. This paper begins by countering this prominent view with a brief outline of some of the more positive scenes that have played out on Iraq’s streets, including the successful elections of 2005 and 2009. The bulk of the paper builds on this discussion to detail the various protest movements that have emerged across Iraq since 2003, including those organised by Shia clerics, minority movements, women’s organisations and Iraqi worker unions. This paper concludes by arguing that the willingness of normal Iraqi citizens to exercise their democratic right to protest indicates the degree to which democratic ideals are taking hold in Iraq and represents a fundamental step towards a more peaceful and inclusive future.

Real-time lane detection on suburban streets using visual cue integration

The detection of lane boundaries on suburban streets using images obtained from video constitutes a challenging task. This is mainly due to the difficulties associated with estimating the complex geometric structure of lane boundaries, the quality of lane markings as a result of wear, occlusions by traffic, and shadows caused by road-side trees and structures. Most of the existing techniques for lane boundary detection employ a single visual cue and will only work under certain conditions and where there are clear lane markings. Also, better results are achieved when there are no other onroad objects present. This paper extends our previous work and discusses a novel lane boundary detection algorithm specifically addressing the abovementioned issues through the integration of two visual cues. The first visual cue is based on stripe-like features found on lane lines extracted using a two-dimensional symmetric Gabor filter. The second visual cue is based on a texture characteristic determined using the entropy measure of the predefined neighbourhood around a lane boundary line. The visual cues are then integrated using a rulebased classifier which incorporates a modified sequential covering algorithm to improve robustness. To separate lane boundary lines from other similar features, a road mask is generated using road chromaticity values estimated from CIE L*a*b* colour transformation. Extraneous points around lane boundary lines are then removed by an outlier removal procedure based on studentized residuals. The lane boundary lines are then modelled with Bezier spline curves. To validate the algorithm, extensive experimental evaluation was carried out on suburban streets and the results are presented. 

The streets of Iraq: protests and democracy after Saddam

This chapter seeks to document and examine the Iraqi people’s exercise of their right to protest and the influence these protests have had on the political landscape of the post-Saddam era. Since 2003, the Iraqi people have frequently taken to the streets en masse, to air their concerns about everything – from the ongoing US-led occupation to the government’s failure to provide basic security and infrastructure and to the airing of ‘indecent’ programmss on Iraqi television. This paper concludes by arguing that Iraqi citizens who play an active role in their own governance and participate in democratic mechanisms such as elections and mass demonstrations are helping to create a more robust democracy.

The social life of commercial streets

The social life of cities is a key concept related to social cohesion, which has been the subject of extensive studies in several disciplines including sociology, psychology and the built environment. Social life studies conducted in the built environment discipline have mostly focused on city centres; while the significance of neighbourhoods as integral elements have been sometimes overlooked. As a result, this research will specifically explore commercial streets in residential suburbs. Suburbs are frequently perceived to be lacking in vitality and street life. The method of inquiry in this research investigates how the physical characteristics of commercial streets can either promote, affect or mitigate the social life of neighbourhoods and generate a sociable environment. Therefore, this study captures the social behaviour of three commercial streets in Geelong, Australia. This paper utilizes a qualitative approach to the study of the social life of commercial streets. The primary methodology used in this research is recording, documenting and mapping users’ activities through behavioural observation. The observations have been conducted in four days (on two weekdays and two weekends). The case study has been divided into eight sections that are similar in length. Short movies of 30 seconds have been recorded from each section, every two hours from 8:00 am to 10:00 pm. Afterwards, the movies have been transmitted into street mappings, documenting the type of activities, placement of activities, gender and approximate age by exploiting suitable pictograms. There are several physical characteristics that are believed to be contributing to the social life of commercial streets. This study utilizes a bottom-up approach to evaluate the complexities of the role that built environment plays in terms of vitality through the three selected characteristics, including typomorphology and street layout, diversity of uses, and soft facades. Better understanding of how neighbourhood environments influence the social life of neighbourhoods can provide academics and professionals in architecture and urban design with sound evidence on which to base future research and design.

Legislation to protect whistle-blowers in Victoria

Protection afforded to whistleblowers under Victoria's Whistleblower Protection Act - benefits and costs of providing protection - types of disclosures that are protected and people who can claim protection under the Act - determining if a matter involves a public interest disclosure - investigation of disclosures by the Ombudsman, and other public bodies - action upon completion of an investigation - protection afforded to the Ombudsman.

Environmental undertakings: Ownership and obligations

Enforceable undertakings have proven to be a useful mechanism for achieving regulatory compliance in the trade practices context. This paper argues that enforceable environmental undertakings could prove equally useful. An administrative measure of this kind has the potential, if used appropriately, to encourage organisations to take greater ownership of their problems and responsibility for finding solutions.

Perceptions of local neighbourhood environments and their relationship to childhood overweight and obesity

OBJECTIVES: To examine associations between parent and child perceptions of the local neighbourhood and overweight/obesity among children aged 5–6 and 10–12 y. DESIGN: Cross-sectional survey. SUBJECTS: In total, 291 families of 5–6-y-old and 919 families of 10–12-y-old children. MEASURES: Parent's perceptions of local neighbourhood and perceived child access to eight local destinations within walking distance of home; 10–12-y-old children's perception of local neighbourhood; socio-demographic characteristics (survey). Children's height and weight (measured). RESULTS: No perceptions of the local neighbourhood were associated with weight status among 5–6-y-old children. Among 10–12-y-old children, those whose parents agreed that there was heavy traffic in their local streets were more likely to be overweight or obese (OR=1.4, 95% CI=1.0–1.8), and those whose parents agreed that road safety was a concern were more likely to be obese (OR=3.9, 95% CI=1.0–15.2), compared to those whose parents disagreed with these statements. CONCLUSIONS: This study suggests that parental perceptions of heavy traffic on local streets and concern about road safety may be indirect influences on overweight and obesity among 10–12-y-old children. Future work should also consider perceptions of the neighbourhood related to food choice.

Neighborhood walkability and the walking behavior of Australian adults

Background
The physical attributes of residential neighborhoods, particularly the connectedness of streets and the proximity of destinations, can influence walking behaviors. To provide the evidence for public health advocacy on activity-friendly environments, large-scale studies in different countries are needed. Associations of neighborhood physical environments with adults’ walking for transport and walking for recreation must be better understood.

Method
Walking for transport and walking for recreation were assessed with a validated survey among 2650 adults recruited from neighborhoods in an Australian city between July 2003 and June 2004, with neighborhoods selected to have either high or low walkability, based on objective measures of connectedness and proximity derived from geographic information systems (GIS) databases. The study design was stratified by area-level socioeconomic status, while analyses controlled for participant age, gender, individual-level socioeconomic status, and reasons for neighborhood self-selection.

Results
A strong independent positive association was found between weekly frequency of walking for transport and the objectively derived neighborhood walkability index. Preference for walkable neighborhoods moderated the relationship of walkability with weekly minutes, but not the frequency of walking for transport—walkability was related to higher frequency of transport walking, irrespective of neighborhood self-selection. There were no significant associations between environmental factors and walking for recreation.

Conclusions
Associations of neighborhood walkability attributes with walking for transport were confirmed in Australia. They accounted for a modest but statistically significant proportion of the total variation of the relevant walking behavior. The physical environment attributes that make up the walkability index are potentially important candidate factors for future environmental and policy initiatives designed to increase physical activity.
