Synthesis and physical property characterisation of phosphonium ionic liquids based on P(O)2(OR)2− and P(O)2(R)2− anions with potential application for corrosion mitigation of magnesium alloys

Phosphonium cation based ionic liquids (ILs) have become of interest due to their unique chemical and electrochemical stability as well as their promising tribological properties. At the same time, interest has also grown in the use of phosphate and phosphinate based ionic liquids for corrosion protection of reactive metals. In this work we describe the synthesis and characterization of six novel ionic liquids based on the tetraalkylphosponium cation coupled with organophosphate and organophosphinate anions and their sulfur analogues. The conductivity and viscosity of these ILs has been measured and discussed in terms of the nature of the interactions, effect of anion basicity and the extent of ionic character. The reaction of the IL with a ZE41 magnesium aerospace alloy surface is also demonstrated.

Cuticle modifications and dyeing property of ultrasonically scoured wool

Ultrasonics has the potential to reduce the cost and environmental impact of textile processing. This work investigates the effects of utrasonic irradiation during wool scouring on fibre surface properties and fibre dyeing rate. A range of ultrasonic frequencies were used in the scouring bath to examine the forms of fibre cuticle damage. It was shown that ultrasonically scoured wool underwent some modifications of the fibre surface structure which resulted in a higher rate of dye uptake by the fibres, when compared with the conventionally scoured wool. The lower the ultrasonic frequency the more sever was the cuticle damage to wool during scouring, hence the higher the fibre dye uptake.

Can virtual world property be considered a digital good?

What types of goods should be considered digital goods? This paper discusses the question of whether virtual property, such as items available in virtual world environments like Linden Lab’s Second Life and Blizzard’s World of Warcraft, should be considered a valid digital good. The makeup of a virtual property items are explored in this paper and their key features compared and contrasted with that of digital goods. Common examples of digital goods include: electronic books, software, digital music and digital movies. These goods are considered a tangible commodity, that is they have an unlimited supply and secondly they are in a digital/binary form (a sequence of 1’s and 0s’). When looking at why a virtual property items should be included in the category of ‘digital goods’, it is important to consider how items in a virtual world come to exist and how the availability of these items are often controlled by publishers and developers. The aim of this paper is show that digital goods should not be limited to the traditional views such as electronic books, software, music and movies; but in fact the term ‘digital good’ should also include the active market of virtual property
items.

A multidiscipline approach to governing virtual property theft in virtual worlds

The crime of virtual property theft has become a serious problem in virtual worlds in recent years. Players of these games are repeatedly falling victim to this crime, with little or no repercussion for the offender. Virtual property often has a substantial real world monetary value and the theft of such items impacts greatly on victims. The problem of virtual property theft is complex, involving many legal, regulatory and technological factors. As such, trying to address this problem in a single dimension is not sufficient, each factor need to be addressed with a multidisciplinary approach. In addressing this problem, this paper provides a model for describing the issue of virtual property trading and the issues associated with virtual property theft. The paper also proposes an approach for handling virtual property theft based on improvements to laws related to virtual property and theft, improvements to the virtual world software components and better regulation from governments.

Succession and Indigenous Australians : addressing Indigenous customary law notions of 'property' and 'kinship' in a succession law context

The purpose of this article is to critically evaluate the existing capacity of Indigenous people to exercise succession rights against their estate. This article begins with a discussion of the sources of the general succession laws in Australia, noting that they have derived from UK law, where the common law notions of property, property rights and family, including the expectational right to succeed to property, are all important factors. These common law notions do not easily fit within the spectrum of Indigenous customary law. Generally, many Indigenous Australians will die without executing a valid will (ie, they die intestate) and it is here that this article undertakes an examination of the general intestacy laws in all Australian jurisdictions noting the inadequacy of the provisions to recognise Indigenous persons’ spiritual and cultural obligations to property, land or otherwise, together with a failure to distinguish extended Indigenous kinship relationships under Indigenous customary law. It is argued that Indigenous people who die intestate should be supported by a flexible and adaptive intestacy framework, responsive to the full customary and cultural responsibilities of the deceased, thus promoting an organic and developmental approach to succession entitlements.

Warrock collection: original line drawings by fourth year Deakin University architecture students of the Warrock Homestead, a local heritage listed property in Victoria

This collection includes the original line drawings by fourth year Deakin University architecture students of a well known local heritage listed property, the Warrock homestead. The Warrock homestead consisted of detailed original timber structures of the 19th century. The drawings are the result of a conservation project funded by the Commonwealth Government of Australia National Estate Grants program. In 1999 a further deposit of original reports relating to individual buildings on the property was received. The collection consists of monographs, photographs and photograph negatives, architectural drawings, VHS tapes and ephemera.

The relationship between building adaptation and property attributes

Using a database of building adaptation and property attributes this research examined every adaptation event in Melbourne's CBD between 1998 and 2008. The importance of property attributes was derived using a principal component analysis and a weighted index of optimal decision making attributes was proposed; the Preliminary Assessment Adaptation Model (PAAM). The findings indicate the relationship between property attributes is more complex than hitherto held. Overall physical attributes were found to be more important than others such as economic, environmental, legal and social attributes; however physical attributes alone are not important and are closely related to other attributes.

The activities and impacts of part-time employment on full time undergraduate students in property and construction courses in Australia

This paper examines the extent of part-time employment of undergraduate students enrolled in property and construction related courses in five universities across Australia. Forty five percent of the students responded to a questionnaire on their part-time work. Past research reveals that there is need for a more accurate understanding as to why students seek part-time work to the extent that they do and that working long hours has a negative effect on the study patterns of undergraduate students. Increased employer work demands results in less time available for study and an inability to attend lectures because of work. There is growing concern that students are increasingly disinterested in connecting with the broader and total university experience and are instead, seeking to adopt a minimalist approach to education.

Analysis of current research for Property and construction students’ results reveals that students are working on average 18 hours per week during semester time. The students therefore appear to be working beyond what is considered beneficial to their studies, although their contextual understanding and work ethic improves.

The paper concludes with some approaches that could re- engage students into the learning process. It may be helpful to develop a partnership between the University and the industry thereby providing work experience that complements the program of study. Otherwise students may not get the range of experience they need and may struggle to find the linkages between theory and practice.
