Understanding urban rail travel for improved patronage forecasting

Improved forecasting of urban rail patronage is essential for effective policy development and efficient planning for new rail infrastructure. Past modelling and forecasting of urban rail patronage has been based on legacy modelling approaches and often conducted at the general level of public transport demand, rather than being specific to urban rail. This project canvassed current Australian practice and international best practice to develop and estimate time series and cross-sectional models of rail patronage for Australian mainland state capital cities. This involved the implementation of a large online survey of rail riders and non-riders for each of the state capital cities, thereby resulting in a comprehensive database of respondent socio-economic profiles, travel experience, attitudes to rail and other modes of travel, together with stated preference responses to a wide range of urban travel scenarios. Estimation of the models provided a demonstration of their ability to provide information on the major influences on the urban rail travel decision. Rail fares, congestion and rail service supply all have a strong influence on rail patronage, while a number of less significant factors such as fuel price and access to a motor vehicle are also influential. Of note, too, is the relative homogeneity of rail user profiles across the state capitals. Rail users tended to have higher incomes and education levels. They are also younger and more likely to be in full-time employment than non-rail users. The project analysis reported here represents only a small proportion of what could be accomplished utilising the survey database. More comprehensive investigation was beyond the scope of the project and has been left for future work.

Mixed pixel analysis and assessment for flood mapping

The most difficult operation in flood inundation mapping using optical flood images is to map the ‘wet’ areas where trees and houses are partly covered by water. This can be referred to as a typical problem of the presence of mixed pixels in the images. A number of automatic information extracting image classification algorithms have been developed over the years for flood mapping using optical remote sensing images, with most labelling a pixel as a particular class. However, they often fail to generate reliable flood inundation mapping because of the presence of mixed pixels in the images. To solve this problem, spectral unmixing methods have been developed. In this thesis, methods for selecting endmembers and the method to model the primary classes for unmixing, the two most important issues in spectral unmixing, are investigated. We conduct comparative studies of three typical spectral unmixing algorithms, Partial Constrained Linear Spectral unmixing, Multiple Endmember Selection Mixture Analysis and spectral unmixing using the Extended Support Vector Machine method. They are analysed and assessed by error analysis in flood mapping using MODIS, Landsat and World View-2 images. The Conventional Root Mean Square Error Assessment is applied to obtain errors for estimated fractions of each primary class. Moreover, a newly developed Fuzzy Error Matrix is used to obtain a clear picture of error distributions at the pixel level. This thesis shows that the Extended Support Vector Machine method is able to provide a more reliable estimation of fractional abundances and allows the use of a complete set of training samples to model a defined pure class. Furthermore, it can be applied to analysis of both pure and mixed pixels to provide integrated hard-soft classification results. Our research also identifies and explores a serious drawback in relation to endmember selections in current spectral unmixing methods which apply fixed sets of endmember classes or pure classes for mixture analysis of every pixel in an entire image. However, as it is not accurate to assume that every pixel in an image must contain all endmember classes, these methods usually cause an over-estimation of the fractional abundances in a particular pixel. In this thesis, a subset of adaptive endmembers in every pixel is derived using the proposed methods to form an endmember index matrix. The experimental results show that using the pixel-dependent endmembers in unmixing significantly improves performance.

The novel as social satire: 60 years later, the wind done gone and the limitations of fair use

The absence of the doctrine of fair use from Australian copyright law has been a bone of contention in Australia after the Australia-United States Free Trade Agreement (FTA). As the Australian government reformed the Copyright Act 1968 (Cth) in the aftermath of the FTA it eschewed the option of adopting fair use. Instead, Australia chose to incorporate a version of fair use into its existing fair dealing framework. Accordingly, the Copyright Amendment Act 2006 (Cth) inserted ss 41A and 103AA into the Copyright Act. These provisions provide that a fair dealing with a copyright protected work does not constitute an infringement if it is done for the purposes of parody or satire. These provisions codify part of the ratio of the United States Supreme Court in the seminal case of Campbell v Acuff Rose Music. However, the parameters of these new provisions are unexplored and the sparse nature of fair dealing jurisprudence means that the true meaning of the provisions is unclear. Moreover, two cases from the United States, SunTrust Bank v Houghton Mifflin and Salinger v Colting, underline just how important it is to have legal rules that protect literary ‘re-writes’. Both cases involved authors using an original novel to ‘write back’ to the original author and the broader culture. ‘Writing back’ or the ‘re-write’ has a firm basis in literature. It adds something invaluable to our culture. The key question is whether our legal landscape can allow it to flourish. This paper examines the interaction between fair use and literary re-writes.

Copyright future copyright freedom

If copyright law does not liberate us from restrictions on the dissemination of knowledge, if it does not encourage expressive freedom, what is its purpose? This volume offers the thinking and suggestions of some of the finest minds grappling with the future of copyright regulation. The Copyright Future Copyright Freedom conference held in 2009 at Old Parliament House Canberra brought together Lawrence Lessig, Julie Cohen, Leslie Zines, Adrian Sterling, Sam Ricketson, Graham Greenleaf, Anne Fitzgerald, Susy Frankel, John Gilchrist, Michael Kirby and others to share the rich fruits of their experience and analysis. Zines, Sterling and Gilchrist outline their roles in the genesis and early growth of Australian copyright legislation, enriching the knowledge of anyone asking urgent questions about the future of information regulation.

Copyright vision : copyright jails

This article, published in ON LINE Opinion on 26 October 2006, discusses the broad ranging amendments to the Copyright Act which (in part) implement obligations under the Australia-US Free Trade Agreement (AUSFTA) which were introduced into parliament on October 19, 2006. It covers issues relating to the criminalisation of copyright infringement, user rights and liabilities, and Technological Protection Measures (TPMs).

A situated approach to historical thinking in the Australian Curriculum : History

This paper focuses on the importance of foregrounding an emphasis on the development of historical thinking in the implementation of the Australian Curriculum: History as a way of making the study of history meaningful for their students. In doing so, it argues that teachers need to take up the opportunity to situate the study of Asia as a significant component of the curriculum’s ‘Australia in a world history approach’. In the discussion on the significance of historical thinking, the paper specifically addresses those seven historical concepts articulated in the new history curriculum by drawing from the international scholarship in the field of history education on the ways in which children and adolescents think about historical content and concepts.

Online Copyright Infringement Discussion Paper July 2014

The Paper, by consideration of the issue of authorisation, addresses a very practical development in commerce. Online copyright infringement is now not only about unauthorised uses of cinematograph films but has filtered down to become more prevalent amongst small to medium enterprises (SME), as some competitors embrace online trading by aggressively and often unlawfully, seeking market share. It is understandable that internet service providers (ISPs), as gatekeepers of internet traffic, may be considered as being more than a conduit of contravening conduct but not a joint tortfeasor involved in a common design. In between those extremes lies the concept of authorisation in copyright which has a long history in Australia since the Copyright Act 1905 (Cth). The text of s 101(1A) of the Copyright Act, in particular s 101(1A)(a) and (c), derived from statements of Gibbs J in Moorhouse.

Why Australians should back Turnbull in the stoush over copyright

Attorney-General George Brandis is at loggerheads with Communications Minister Malcolm Turnbull over proposed reforms to the Copyright Act. Brandis wants ISPs to take more responsibility for copyright infringement by their users. Turnbull says that they shouldn’t be required to police their subscribers’ activities. Here’s how to understand what’s at stake in the debate.

Claiming the moral high ground in the copyright wars

Copyright was once one of the more obscure areas of law. It applied primarily to resolve disputes between rival publishers, and there was a time, not too long ago, when ordinary people gave it no thought. Copyright disputes were like subatomic particles: everyone knew that they existed, but nobody had ever seen one. In the digital age, however, copyright has become a heated, passionate, bloody battleground. The 'copyright wars' now pitch readers against authors, pirates against publishers, and content owners against communications providers. Everyone has heard a movie producer decry the rampant infringement of streaming sites, or a music executive suggest that BitTorrent is the end of civilisation as we know it. But everyone infringes copyright on an almost constant basis - streaming amateur videos with a soundtrack that isn't quite licensed, filesharing mp3s, copying LOLcat pictures from Facebook, posting pictures on Pinterest without permission, and so on - and most know full well they're in breach of the law.

Robbery under arms: Copyright law and the Australia-United States free trade agreement

TThis article considers the radical, sweeping changes to Australian copyright law wrought by the Australia–United States Free Trade Agreement 2004 (AUSFTA). It contends that the agreement will result in a “piracy of the public domain”. Under this new regime, copyright owners will be able to obtain greater monopoly profits at the expense of Australian consumers, libraries and research institutions, as well as intermediaries, such as Internet service providers. Part One observes that the copyright term extension in Australia to life of the author plus 70 years for works will have a negative economic and cultural impact — with Australia’s net royalty payments estimated to be up to $88 million higher per year. Part Two argues that the adoption of stronger protection of technological protection measures modelled upon the Digital Millennium Copyright Act 1998 (U.S.) will override domestic policy–making processes, such as the Phillips Fox Digital Agenda Review, and judicial pronouncements such as the Stevens v Sony litigation. Part Three questions whether the new safe harbours protection for Internet service providers will adversely affect the sale of Telstra. This article concludes that there is a need for judicial restraint in interpreting the AUSFTA. There is an urgent call for the Federal Government to pass ameliorating reforms — such as an open–ended defence of fair use and a mechanism for orphan works. There is a need for caution in negotiating future bilateral trade agreements — lest the multinational system for the protection of copyright law be undermined.

Digital copyright and the consumer revolution: Hands off my iPod

This book documents and evaluates the growing consumer revolution against digital copyright law, and makes a unique theoretical contribution to the debate surrounding this issue. With a focus on recent US copyright law, the book charts the consumer rebellion against the Sonny Bono Copyright Term Extension Act 1998 (US) and the Digital Millennium Copyright Act 1998 (US). The author explores the significance of key judicial rulings and considers legal controversies over new technologies, such as the iPod, TiVo, Sony Playstation II, Google Book Search, and peer-to-peer networks. The book also highlights cultural developments, such as the emergence of digital sampling and mash-ups, the construction of the BBC Creative Archive, and the evolution of the Creative Commons. Digital Copyright and the Consumer Revolution will be of prime interest to academics, law students and lawyers interested in the ramifications of copyright law, as well as policymakers given its focus upon recent legislative developments and reform proposals. The book will also appeal to librarians, information managers, creative artists, consumers, technology developers, and other users of copyright material.

Creation and copyright law: The case of 3D printing

The Australian Law Reform Commission is conducting an inquiry into copyright law and the digital economy in 2012 and 2013.The President, Rosalind Croucher, stated: “While the Copyright Act has been amended on occasion over the past 12 years to account for digital developments, these changes occurred before the digital economy took off. The Australian Law Reform Commission will need to find reforms that are responsive to this new environment, and to future scenarios that are still in the realm of the imagination. It is a complex and important area of law and we are looking forward to some robust debate and discussion during the course of this very important Inquiry.”

Creating an Innovation Exception? Copyright Law as the Infrastructure for Innovation

Innovation is clearly essential for economic growth, cultural development and personal autonomy. Yet the relationship between innovation and copyright law in Australia is uncertain and perhaps overly restrictive. After the Australia-United States Free Trade Agreement Australia now has a copyright regime that can broadly be
described as a lock up and lock out scheme. Whilst the Australian Government has paid lip service to innovation the Australian Copyright Act, which provides the essential legal infrastructure for innovation, now privileges the rights of owners over the interests of the public. In particular, the Copyright Act neglects to create a specific exception for technology innovation. If there is to be some coherence in Australia
thinking with regards to innovation and copyright policy it is crucial that such an exception be created. Arguably, it is possible that such an exception can withstand the scrutiny of the three step test. At present the only ‘exception’ that can be said to exist is in the form of the limits of the authorisation liability provisions or the ISP safe harbour scheme. Australian copyright law needs something more substantial than that
and needs for there to be a clear hierarchy between the exceptions and the liability provisions.

Creative choices : changes to Australian copyright law and the future of the public domain

Changes to Australian copyright law introduced under the Australia–United States Free Trade Agreement will diminish the public domain, criminalise common copyright infringing practices and locally introduce significant portions of the controversial 1998 American Digital Millennium Copyright Act. This paper examines these imminent changes to Australian copyright law, with specific attention to the potential effects of the extended duration of copyright protection and the introduction of technological anti-circumvention measures. It argues that public domain-enhancing activities are crucial for sustaining cultural creativity and technological innovation, and discusses the potential role of the Creative Commons movement in establishing economically viable and legal alternatives to the current model of trade-oriented copyright reform.
