Predictive mapping of powerful owl (Ninox strenua) breeding sites using Geographical Information Systems (GIS) in urban Melbourne, Australia

Urban expansion is a principal process threatening biodiversity globally. It is predicted that over half of the world's population will reside in urban centres by 2010. If we are to conserve biodiversity, a shift in perspective from traditional ecological studies based in natural environments, to studies based in less natural environments is paramount. To effectively conserve species which occur in urban environments, comprehensive analysis is necessary to determine the processes that are driving this urban usage. Geographical Information Systems (GIS) technology provides a valuable tool for efficient spatial analysis and predictive mapping of species distributions.

This study used GIS to analyze current breeding sites for the powerful owl, a vulnerable top order predator in urban Melbourne, Australia. GIS analysis suggests that a number of ecological attributes were influencing powerful owl usage of urban environments. Using these ecological attributes, predictive mapping was undertaken, which identified a number of potential breeding sites for powerful owls within urbanized Melbourne.

Urban environments are traditionally perceived as “the wastelands” of natural environments, however, this study demonstrates that they have the potential to support apex predators, an important finding for the management of rare and threatened species.

Professional standards for physical education teachers' professional development : technology for performance?

Background: The widespread and diverse models of professional standards for teaching raise questions with respect to the need to provide teachers with a pathway for continuing professional development balanced with the public nature of surveillance and accountability that may accompany standards. Ways of understanding technologies of power in relation to standards for
teaching gives us a new language and, in turn, new questions about the standards agenda in the physical education profession.
Purpose: To analyse how one health and physical education (HPE) teacher worked with Education Queensland’s (EQ) professional standards for teaching within the broader context of teacher professional development and renewal.
Participants and setting: An experienced HPE teacher working in an urban secondary school was the ‘case’ for this article. Tim was the only experienced HPE teacher within the larger pilot study of 220 selected teachers from the volunteer pool across the state.
Data collection: The case-study data comprised two in-depth interviews conducted by the first author, field notes from workshops (first author), teacher diaries and work samples, notes from focus groups of which Tim was a member, and electronic communications with peers by Tim
during the course of the evaluation.
Findings: Tim was supportive of the teaching standards while they did not have a strong evaluative dimension associated with technologies of power. He found the self-regulation associated with his reflective practices professionally rewarding rather than being formalised within a prescribed
professional development framework.
Conclusion: Tim’s positive response to the professional standards for teaching was typical of the broader pilot cohort. The concept of governmentality provided a useful framework to help map how the standards for teaching were received, regardless of teacher specialisation or experience.
We suggest that it is not until the standards regimes are talked about within the discourses of
power (e.g. codification for career progression, certification for professional development imperatives) that we can understand patterns of acceptance and resistance by teachers to policies
that seek to shape their performance.

Costs of Silver Gulls Larus novaehollandiae in an urban environment

Silver Gull economic impacts were evaluated during 1998 to 2003 in the Greater Melbourne area. Roof nesting and roosting created substantial problems. Annual cost for cleaning, maintenance, damage, repairs and mitigation was $3,570,000. Roof corrosion was $0.9 million. Reducing anthropogenic food availability is the key to reducing problems.

Interactive urban language and city growth

The thesis is a refinement of semiotic theory in architecture which aims towards developing a conversation between Western theory and the Eastern city. Using theoretical bases including semiotic theory, Japanese analytical text and analogies of cultural products, this thesis proposes that urban language can be perceived and analysed.

Spaces of empire : culture, discourse, and urban formation with particular reference to British Hong Kong, 1842-1914

Traces the ideological formations of British colonialism using the techniques of modern European cartography to examine the practices of spatial production in Hong Kong's capital city, Victoria. This examination demonstrates how notions of British cultural identity and self-representation were inscribed throughout the colonial urban environment by considering the ways in which the British colonial authorities sought to condition, control, and maintain the organisation of space.

Urban streetscape bryophytes and heavy metals

This thesis presents the first large scale examination of urban bryophytes in Australia in terms of species distribution, screening as hyperaccumulators and use as biomonitors. It provides baseline data to allow future comparison of the distribution of urban bryoflora with respect to arsenic and the associated contribution of cadmium, copper, zinc and lead.

Advancing architecture ecologies : energy principles in nature and urban systems

The search for a coherent approach to optimising the delivery of sustainable development has moved from rhetoric to reality, shaped by international drivers such as the UN Millennium Development Goal and the UN 'Decade of Education for sustainable development 2005- 2014'. Emphasis has been recently placed by Governmental bodies on creativity and innovation as a way to promote and sustain the social, cultural and economic well-being. This has led to, amongst other things, the development of a series of new initiatives to promote sustainable development. There is still a lack of understanding of the impacts of sustainability on architecture and their associated and interrelated ecologies because, at least in part, there is no significant joined up thinking regarding the implications of sustainability across the whole design, implementation and operation processes. There is a considerable challenge to ensure integration, cross-fertilisation and dissemination to provide meaningful outputs from the vast array of ecological systems with their differing structures. This paper explores the processes rather than products of ecological systems and possibilities for a credible integral system that guide sustainable development and advance architecture ecologies. The paper traces back the roots of the divorce between architecture profession and technology and highlights the importance of reaching back to the true meanings of Techne as key to develop integral sustainable systems. The paper underlines the energy principles that construct ecological principles and provide explanation of how such systems can be interpreted in the built environment. Enriching ecological culture is not a physical development or a large expensive projects but rather in a coherent and focused efforts by a group of professionals, academics, and practitioners with multi disciplinary talents to build a complex and multi facets of integral systems and ideas.

How different is it really? – rural and urban primary students’ use of ICT in mathematics

Information and Communication Technology (ICT) offers the potential for changing mathematics education for both teachers and students. However, how ICT is used, and by whom, is critical to realizing this potential. This paper reports on an investigation of the use of ICT in the learning and teaching of mathematics in rural and urban primary schools in Victoria, Australia. Thirty-six teachers and almost 700 students were surveyed regarding their use of ICT for mathematics at home and at school, with a small number of selected teachers and students taking part in interviews. This paper focuses on students’ perceptions of ICT use. A comparison of rural and urban students’ responses shows little difference across most aspects of ICT use, and where there was a difference, the frequency of rural use almost always exceeded that in urban schools.

A study of building materials to create an identity of traditional Balinese architecture for urban housing

The use or local architecture characteristics is regulated by the spatial planning and building code of Indonesia. Balinese tmditional architecture has existed, coloured the traditional architecture of Indonesia and can be used as Bali's identity that is different from other regions in Indonesia.On the other hand, the cost of such building is high and most of people in urban areas are unable to afford to build in the traditional architecture style, especially in the residential housing sector .. Some of the major components that determine the price of housing units are the price of land, building materials, labour and technology. In developing countries, the first and second components that affect the unit price of the building are building materials representing about 70% and skilled labour respectively (Ural, 1980). Based on this, a good strategy to adopt in order to minimize the price is to manipulate these two components.Based on a literature review and observation, this study will explain which aspects of building material technology can reduce the building cost and how it can maintain the identity of local architecture.The results of the study indicate that the building material can be created to both reduce cost and adopt traditional architecture style as an identity. The materials have some shapes that can be joined easily to facilitate the skill of the worker and yet still be able to adopt the forms of traditional Balinese architecture.

Zonal banning and public order in urban Australia

In recent years, Australian governments of various ideological persuasions at local, state and territory and federal levels have introduced a range of zonal governing techniques to manage the flow of people in urban spaces. Zonal governance involves the identification and formal declaration of a specific urban geographic region to enable police and security personnel to deploy special powers and allied forms of surveillance technologies as a supplement to their conventional public order maintenance functions.

Despite the impetus towards open flows or movement within sovereign territories or larger territorial groupings, such as the European Union, considerable governmental effort has been directed towards the use of new forms of criminal law to re-territorialize urban space through new administrative, property law and regulatory measures. These low-level spatial demarcations introduce various supplementary police powers and discretionary procedures that enhance surveillance within a declared area to increase the level of contemporary urban security. Of particular concern is the legal right to ban or exclude “undesirable” individuals and groups from entering or using certain designated urban zones, to prevent antisocial or violent behavior usually associated with alcohol consumption.

To date, most discussion of the impact of banning and related surveillance measures focuses on illegal migration through ports of entry into sovereign nations and the commensurate burdens this creates for both citizens and non-citizens to authenticate their movements at national geographic borders. This logic is permeating more localized forms of regulation adopted by Australian local and mid-tier state and territory governments to control the movement of people in and out of major event sites and in the urban night-time economy.

A survey of recent reforms in the state of Victoria reveals how this new logic of mass-surveillance aims to promote greater levels of urban security while reshaping the conventional order maintenance functions of both the public and private police. This chapter describes these procedures and their impact in sanctioning the efficient screening of people to promote order in specific zones within the contemporary Australian urban environment, at the expense of more progressive and inclusive crime prevention initiatives. We focus on two exemplars of the intensification of surveillance through zonal governance techniques: ‘major events’ and ‘designated alcohol zones’.

Access to social insurance in urban China: a comparative study of rural-urban and urban-urban migrants in Beijing

 Since 1958 the hukou (household registration) system has assigned Chinese citizens either a rural or urban status. Some studies argue that the rural-to-urban migrants in China who do not have urban hukou are not entitled to urban social insurance schemes, due to institutional discrimination, which applies differing treatment to urban and rural hukou (chengxiang fenge). Although rural-urban migrants participate less in the social insurance system than their counterparts with urban hukou, a closer examination of recent policy developments shows that migrants actually do have the legal right to access the system. This implies that discrimination between rural and urban workers has been declining, and distinctions based on household registration status are less able to explain China's current urban transition. This paper provides a new way of examining Chinese migrants' social insurance participation, by adopting a framework that includes both rural-to-urban migrants and urban-to-urban migrants, which are an important, but less studied, migrant group. Among our key findings are that urban migrants are more likely to sign a labour contract than rural migrants; urban migrants have higher participation rates in social insurance than rural migrants; having a labour contract has a greater impact than hukou status in determining whether Beijing's floating population accesses social insurance; and urban migrants who have signed a labour contract have higher participation rates in social insurance than either rural migrants or urban migrants without a labour contract. © 2013 Elsevier Ltd.

Effects of intergroup contact on attitudes of Chinese urban residents to migrant workers

 One consequence of China's marketisation has been the emergence of a 'floating population' - rural Chinese who migrate to China's cities to work. Many urbanites have negative attitudes towards such migrants. To understand how these negative attitudes might be ameliorated, the paper employs Allport's influential contact hypothesis to investigate whether urbanite-migrant friendships affect attitudes. More negative attitudes were observed among males and older urbanites. There was no effect of simply knowing a migrant, supporting Allport's thesis that non-intimate contact is not sufficient to affect attitudes. Friendship alone did not influence attitudes, but interaction effects were detected between having migrant friends and each of age, income and education. Negative attitudes were reduced among urbanites in older, higher-income and higher-education groups if they had a migrant friend. © 2006 The Editors of Urban Studies.

Sex-biased space-use response to urbanization in an endemic urban adapter

Urbanization impacts on the composition and distribution of wildlife. The tawny frogmouth (Podargus strigoides) is an endemic, nocturnal bird species widespread throughout Australia with recent research highlighting high densities within urban environments. The aim of this study was to investigate homerange size and land-use in response to a gradient of urbanization by determining (a) the key land-use types influencing home-range size and location in the urban landscape (b) whether urbanization impacts on home-range size; and (c) whether the response to urbanization is gender specific. Twelve birds, seven male and five female were radio-tracked within a study zone located in Melbourne, Australia. We used minimum convex polygons (MCP) 95% and 50% fixed-kernel isopleths to calculate home-range size and areas of core use within each home-range. In both the landscape and core areas of their home-range, birds positioned their home-range in areas with more trees, avoiding impervious surfaces and utilizing grassed areas. Male mean kernel home-range was 17.65 ± 4.35 ha and female 6.55 ± 1.40 ha. Male home-ranges contained higher levels of impervious surfaces than females. Modelling demonstrated that as urbanization intensified the home-range size of males increased whereas female home-ranges remained static in size. This research identifies land-use selection and highlights the possibility that spatial behaviour in the species is sex-biased in response to a gradient of urbanization. © 2014 Elsevier B.V.

A study of the impact of environmental surroundings on personal well-being in urban China using a multi-item well-being indicator

We examine the relationship between atmospheric and water pollution, traffic congestion, access to parkland and personal well-being using a survey administered across six Chinese cities in 2007. In contrast to existing studies of well-being determinants by economists which typically employ single-item indicators, we use the Personal Well-being Index (PWI). We also employ the Job Satisfaction Survey (JSS) to measure job satisfaction, which is one of the variables for which we control when examining the relationship between environmental surroundings and personal well-being. Previous research by psychologists has shown the PWI and JSS to have good psychometric properties in western and Chinese samples. A robust finding is that in cities with higher levels of atmospheric pollution and traffic congestion, respondents report lower levels of personal well-being ceteris paribus. Specifically, we find that a one standard deviation increase in suspended particles or sulphur dioxide emissions is roughly equivalent to a 12-13% reduction in average monthly income in the six cities. © 2010 Springer Science+Business Media, LLC.
