Power-law viscous materials for analogue experiments: New data on the rheology of highly-filled silicone polymers

The selection of appropriate analogue materials is a central consideration in the design of realistic physical models. We investigate the rheology of highly-filled silicone polymers in order to find materials with a power-law strain-rate softening rheology suitable for modelling rock deformation by dislocation creep and report the rheological properties of the materials as functions of the filler content. The mixtures exhibit strain-rate softening behaviour but with increasing amounts of filler become strain-dependent. For the strain-independent viscous materials, flow laws are presented while for strain-dependent materials the relative importance of strain and strain rate softening/hardening is reported. If the stress or strain rate is above a threshold value some highly-filled silicone polymers may be considered linear visco-elastic (strain independent) and power-law strain-rate softening. The power-law exponent can be raised from 1 to ~3 by using mixtures of high-viscosity silicone and plasticine. However, the need for high shear strain rates to obtain the power-law rheology imposes some restrictions on the usage of such materials for geodynamic modelling. Two simple shear experiments are presented that use Newtonian and power-law strain-rate softening materials. The results demonstrate how materials with power-law rheology result in better strain localization in analogue experiments.

The exemplification of governance principles within state asset management laws and policies : the case of Indonesia

This chapter reviews aspects of the challenge of reviewing and reforming Indonesian practice within state asset management law and policy specifically related to public housing, public buildings, parklands, and vacant land. A critical issue in beginning this review is how Indonesia currently conceptualizes the notion of asset governance and how this meaning is embodied in recent changes in law and policy and importantly in options for future change. This chapter discusses the potential complexities uniquely Indonesian characteristics such as decentralisation and regional autonomy regime, political history, and bureaucratic culture.

The Growing Pains of Data Breach Notification Law

Mandatory data breach notification laws are a novel statutory solution in relation to organizational protections of personal information. They require organizations which have suffered a breach of security involving personal information to notif'y those persons whose information may have been affected. These laws originated in the state based legislatures of the United States during the last decade and have subsequently garnered worldwide legislative interest. Despite their perceived utility, mandatory data breach notification laws have several conceptual and practical concems that limit the scope of their applicability, particularly in relation to existing information privacy law regimes. We outline these concerns, and in doing so, we contend that while mandatory data breach notification laws have many useful facets, their utility as an 'add-on' to enhance the failings of current information privacy law frameworks should not necessarily be taken for granted.

Welfare reform, surveillance and new paternalism

This paper discusses the situation of welfare claimants, often constructed as faulty citizens and flawed welfare subjects. Many are on the receiving end of complex, multi-layered forms of surveillance aimed at securing socially responsible and compliant behaviours. In Australia, as in other Western countries, neoliberal economic regimes with their harsh and often repressive treatment of welfare recipients operate in tandem with a burgeoning and costly arsenal of CCTV and other surveillance and governance assemblages. The Australian Government’s Centrelink BasicsCard is but one example of welfare surveillance, whereby a percentage of a welfare claimant’s allowances must be spent on ‘approved’ items. The BasicsCard which has perhaps slipped under the radar of public discussion and is expanding nationally, raises significant questions about whether it is possible to encourage people to take responsibility for themselves if they no longer have real control over the most important aspects of their lives. Resistance and critical feedback, particularly from Indigenous people, points to a loss of dignity around the imposition of income management, operational complexity and denial of individual agency in using the BasicsCard, alongside the contradiction of apparently becoming ‘self-reliant’ through being income managed by the welfare state. This paper highlights the lack of solid evidence for the implementation/imposition of the BasicsCard and points to the importance of developing critically based research to inform the enactment of evidence based policy, also acting as a touchstone for governmental accountability. In highlighting issues around the BasicsCard this paper makes a contribution to the largely under discussed area of income management and the growth of welfare surveillance in Australia.

Reasonable adjustments in assessment : putting law and policy into practice in Australia

The Australian Disability Standards for Education 2005 (Cth) require education providers to make reasonable adjustments in educational assessment so that students with disability can participate on the same basis as other students and be able to demonstrate what they know and can do. Reasonableness is governed by a determination of the balance of interests, benefits and detriment to the parties involved. The Standards require providers to consult with students and associates on adjustments, although guidance on how consultation should occur and how the views of students and associates are to be taken into account is vague. In this article, we identify three principles to be considered in order to put appropriate and effective reasonable adjustments in assessment into practice. While Australian law and assessment contexts are used to examine intentions, expectations and practices in educational assessment for students with disability, we argue that these three principles must be considered in any national education system to ensure equitable assessment practices and achieve equitable educational inclusion for students with disability.

The assessment of students with disabilities : the Australian law as to reasonable adjustment and academic integrity

This paper explains the legislation which underpins the right to reasonable adjustment in education for students with disabilities in Australian schools. It gives examples of the kinds of adjustment which may be made to promote equality of opportunity in the area of assessment. It also considers how the law has constructed the border between reasonable adjustment and academic integrity.

Traffic harmony in China? Investigating driver perceptions of traffic law enforcement and social responsibility for harmonious road use.

Social harmony can manifest in many ways. In rapidly motorizing countries like China, a growing area of potential disharmony is road use. The increased ability to purchase a car for the first time and a subsequent increase in new drivers has seen several Chinese cities take unprecedented measures to manage congestion. There is a corresponding need to ensure effective traffic law enforcement in promoting a safe environment for all road users. This paper reports qualitative research conducted with Beijing car drivers to investigate perceptions of unsafe road use, penalties for traffic violations, and improvements for the current system. Overall, the findings suggest awareness among drivers of many of the key risk factors. A perceived lack of clarity in how penalties are determined was identified and drivers in-dicated a desire to know how revenue from traffic fines is used. Several suggestions for improving the current system included school/community education about road risks and traffic law. The rise of private car ownership in China may contribute to a more harmonious personal life, but at the same time, may contribute to a decrease in societal harmony. A major challenge for authorities in any country is to promote the idea of a collective responsibility for road safety (traffic harmony), especially to those who perceive that traffic rules do not apply to them. This is a potentially greater challenge for China as it strives to balance harmony on the road and harmony in the broader society.

The Sapphire Vortex : blending virtual world machinima with real world commentary for effective learning of criminal law

Traditional approaches to teaching criminal law in Australian law schools include lectures that focus on the transmission of abstracted and decontextualised knowledge, with content often prioritised at the expense of depth. This paper discusses The Sapphire Vortex, a blended learning environment that combines a suite of on-line modules using Second Life machinima to depict a narrative involving a series of criminal offences and the ensuing courtroom proceedings, expert commentary by practising lawyers and class discussions.

Sale of Businesses in Australia (2nd ed.)

The greater volume of businesses sold in Australia each year are small to medium enterprises. The administration of business contracts presents far different challenges than, for example, contracts for the sale of goods alone or contracts for the sale of land. The subject matter comprises both real and personal, and tangible and intangible property. Other considerations that do not affect those other commonplace contracts include dealing with employees who are both remaining and departing, taking account of restraints of trade, and the phenomena of the passing of property being different in respect of different forms of property being transferred in the same contract. In keeping with the format of the previous edition, the book is written with the busy practitioner in mind. It deals with the formation of business contracts, all aspects of disclosure both contractual and statutory, the role of agents, and detailed consideration of the different types of subject matter of small business contracts including, the lease of the premises, intellectual property, goodwill, licences, book debts and plant and equipment. It has up to date treatment of income tax implications of the sale and the impact of the latest Commonwealth legislation on dealing with employees of a business on sale. Consistent with the last edition, the book has chapters on time of the essence and completion, personal securities, restraint of trade clauses, special conditions and remedies for breach by both parties and misleading or deceptive conduct by the seller. In relation to personal securities, whilst the current State and Territory based law on Bills of Sale and other Chattel Securities has been the subject of commentary, the proposed national reform agenda has also been commented upon although that legislation is not due until May 2010 at the earliest

A critical regionalist approach to housing design in Vietnam : socio-environmental organisation of living spaces in pre- and post-reform houses

Vietnam has a unique culture which is revealed in the way that people have built and designed their traditional housing. Vietnamese dwellings reflect occupants’ activities in their everyday lives, while adapting to tropical climatic conditions impacted by seasoning monsoons. It is said that these characteristics of Vietnamese dwellings have remained unchanged until the economic reform in 1986, when Vietnam experienced an accelerated development based on the market-oriented economy. New housing types, including modern shop-houses, detached houses, and apartments, have been designed in many places, especially satisfying dwellers’ new lifestyles in Vietnamese cities. The contemporary housing, which has been mostly designed by architects, has reflected rules of spatial organisation so that occupants’ social activities are carried out. However, contemporary housing spaces seem unsustainable in relation to socio-cultural values because they has been influenced by globalism that advocates the use of homogeneous spatial patterns, modern technologies, materials and construction methods. This study investigates the rules of spaces in Vietnamese houses that were built before and after the reform to define the socio-cultural implications in Vietnamese housing design. Firstly, it describes occupants’ views of their current dwellings in terms of indoor comfort conditions and social activities in spaces. Then, it examines the use of spaces in pre-reform Vietnamese housing through occupants’ activities and material applications. Finally, it discusses the organisation of spaces in both pre- and post-reform housing to understand how Vietnamese housing has been designed for occupants to live, act, work, and conduct traditional activities. Understanding spatial organisation is a way to identify characteristics of the lived spaces of the occupants created from the conceived space, which is designed by designers. The characteristics of the housing spaces will inform the designers the way to design future Vietnamese housing in response to cultural contexts. The study applied an abductive approach for the investigation of housing spaces. It used a conceptual framework in relation to Henri Lefebvre’s (1991) theory to understand space as the main factor constituting the language of design, and the principles of semiotics to examine spatial structure in housing as a language used in the everyday life. The study involved a door-knocking survey to 350 households in four regional cities of Vietnam for interpretation of occupancy conditions and levels of occupants’ comfort. A statistical analysis was applied to interpret the survey data. The study also required a process of data selection and collection of fourteen cases of housing in three main climatic regions of the country for analysing spatial organisation and housing characteristics. The study found that there has been a shift in the relationship of spaces from the pre- to post-reform Vietnamese housing. It also indentified that the space for guest welcoming and family activity has been the central space of the Vietnamese housing. Based on the relationships of the central space with the others, theoretical models were proposed for three types of contemporary Vietnamese housing. The models will be significant in adapting to Vietnamese conditions to achieve socioenvironmental characteristics for housing design because it was developed from the occupants’ requirements for their social activities. Another contribution of the study is the use of methodological concepts to understand the language of living spaces. Further work will be needed to test future Vietnamese housing designs from the applications of the models.
