Producing the market for alcohol : the Victorian example

This article analyses three important inquiries into alcohol licensing in Victoria from 1965 to 1986. It argues that each inquiry was directed to produce a market for alcohol, but the 1986 inquiry, in particular, was directed to produce the conditions for the Night-time Economy. Since the mid-twentieth century, Victoria was considered a bell weather state in relation to alcohol licensing and this was increasingly the case when it comes to the state retreating from control over licensing conditions. From the end of six o'clock closing to the 24 hour city, the inquiries transformed the issues related to alcohol from the problems associated with alcohol consumption to the treatment of alcohol as just another consumer commodity.

Self-recognition in live videos by young children : does video training help?

The overall aim of the experiment reported here was to establish whether self-recognition in live video can be facilitated when live video training is provided to children aged 2-2.5 years. While the majority of children failed the test of live self-recognition prior to video training, more than half exhibited live self-recognition post video training. Children who failed the live video self-recognition tasks passed the test of mirror self-recognition. The findings are discussed in light of a video deficit and the potential role of pre-test training in facilitating self-recognition in live video by young children.

Using MediaWiki as an efficient data repository and ubiquitous learning tool : an Australian example

The functionality of MediaWiki ensures it is a valuable learning repository for sharing and storing information. Constructivist learning can be promoted alongside a wiki repository and various wireless u-learning tools such as mobile phones and digital cameras, to encourage students to gather and share a range of primary and secondary information in a variety of subject areas. This paper outlines one initiative adopted at an Australian University specialising in distance education, which uses a MediaWiki as the primary method for content delivery. Over a period of three-years, the Drugs, Crime and Society wiki has evolved into an organic information repository for storing and accessing current research, press and drug agency material that supplements core themes examined in each topic of the curriculum. A constructivist approach has been employed to encourage students to engage in a range of assessable and non-assessable information sharing activities. The paper also demonstrates how the Drugs, Crime and Society wiki can be accessed through various wireless u-learning technologies, which enables students undertaking field placements to add and share primary information with other students and practitioners working in the drugs field.

The role of strain on the recrystallization behaviour of hot worked and annealed magnesium alloy Mg-3Al-1Zn

The present work examines the microstructure that evolves during the hot deformation and subsequent annealing of magnesium alloy AZ31. In particular, the role of strain on the progression of dynamic recrystallization (DRX) and post-deformation recrystallization is investigated. It is found that the grain size developed after post-deformation recrystallization is larger when the deformation strain, and hence the degree of DRX, is low (for strains up to 0.4). Also, the kinetics of post-deformation recrystallization are found to be independent of strain for strain values of 0.4 and above. Whilst increasing strain alters the texture of the un-recrystallized microstructure (for the deformation mode examined), the texture does not change significantly during post-deformation recrystallization.

Time and energy constraints in demanding phases of the annual cycle : an example of time limitation in refuelling migratory swans

The daily metabolizable energy intake of an animal is potentially limited by either the available feeding time or by its capacity to process energy. Animals are generally considered not to be time-limited but rather to be energy-processing-limited. This is concluded from the common observation that an animal's feeding time per day increases with a decrease in food density. We argue that such changes in feeding time are in theory also expected when no constraints are operating. Thus, a study of the constraints on energy intakes of free-living animals should be performed during demanding phases of the year. As an example, we collected data on time and energy budgets of Bewick's swan (Cygnus columbianus bewickii) refuelling during migration on fennel pondweed (Potamogeton pectinatus) tubers in two years differing two-fold in tuber biomass density. As predicted by time limitation, the feeding time (defined as the time with the head submerged) did not change in response to a change in food biomass density, both within and between years (averaging 12.2 h d⁻¹). Contrary to energy-processing limitation, and again in line with time limitation, the daily metabolizable energy intake varied, being greater in the year with high than in the year with low food densities. We conclude that more studies are needed of animals operating under demanding conditions before it can be assessed whether free-living animals are generally energy-processing- or time-limited.

The economic benefits of reducing physical inactivity : an Australian example

Background: Physical inactivity has major impacts on health and productivity. Our aim was to estimate the health and economic benefits of reducing the prevalence of physical inactivity in the 2008 Australian adult population. The economic benefits were estimated as ‘opportunity cost savings’, which represent resources utilized in the treatment of preventable disease that are potentially available for re-direction to another purpose from fewer incident cases of disease occurring in communities.
Methods: Simulation models were developed to show the effect of a 10% feasible, reduction target for physical inactivity from current Australian levels (70%). Lifetime cohort health benefits were estimated as fewer incident cases of inactivity-related diseases; deaths; and Disability Adjusted Life Years (DALYs) by age and sex. Opportunity costs were estimated as health sector cost impacts, as well as paid and unpaid production gains and leisure impacts from fewer disease events associated with reduced physical inactivity. Workforce production gains were estimated by comparing surveyed participation and absenteeism rates of physically active and inactive adults, and valued using the friction cost approach. The impact of an improvement in health status on unpaid household production and leisure time were modeled from time use survey data, as applied to the exposed and non-exposed population subgroups and valued by suitable proxy. Potential costs associated with interventions to increase physical activity were not included. Multivariable uncertainty analyses and univariate sensitivity analyses were undertaken to provide information on the strength of the conclusions.
Results: A 10% reduction in physical inactivity would result in 6,000 fewer incident cases of disease, 2,000 fewer deaths, 25,000 fewer DALYs and provide gains in working days (114,000), days of home-based production (180,000) while conferring a AUD96 million reduction in health sector costs. Lifetime potential opportunity cost savings in workforce production (AUD12 million), home-based production (AUD71 million) and leisure-based production (AUD79 million) was estimated (total AUD162 million 95% uncertainty interval AUD136 million, AUD196 million).
Conclusions: Opportunity cost savings and health benefits conservatively estimated from a reduction in population-level physical inactivity may be substantial. The largest savings will benefit individuals in the form of unpaid production and leisure gains, followed by the health sector, business and government.

Sui generis protection for plant varieties and traditional agricultural knowledge : the example of India

Explores the sui generis protection of intellectual property, particularly patents, in biotechnology and traditional agricultural knowledge under Indian law. Focuses on the impact of amendments to the Patents Act 1970 and of the Plant Variety Protection and Farmers' Rights Act 2001 and Biological Diversity Act 2002.

Traditional knowledge, biological resources and intellectual property rights in Asia : the example of the Philippines

The relationship between traditional knowledge and intellectual property rights has become a topic for intensive debates at the national level, in various international settings and within and among different UN agencies, including the World Intellectual Property Organisation (WIPO), the UN Food and Agriculture Organisation (FAO), UNESCO, UNCTAD and the United Nations Environment Programme (UNEP). However, a consensus on a definition of traditional knowledge has yet to emerge due to persistent differences in perception. On the one hand, indigenous communities hold locally specific and holistic views of traditional knowledge, which are difficult to place within the framework of current intellectual property rights. Governments of developing countries, on the other hand, mostly focus on clearly defined aspects of traditional knowledge and their interpretation in the national interest and as expressions of national culture. Asian governments, in particular, have advocated the latter view. The Philippines provide an exception due to a tradition of recognising indigenous people as separate "cultural communities". However, the practical implementation of so-called "community intellectual rights" thus far is largely confined to access and benefit sharing rules, compensation requirements for traditional farmers and defensive protection measures such as digital libraries documenting traditional knowledge.

Interpretation — appropriation : (making) an example of labor process theory

In this article, the author explores ethically problematic relations that may be reproduced within a genre of interpretive organizational research: namely, (U.K.) labor process theory (LPT). Although the author endorses LPT’s critical and explicitly antioppressive values, he argues that interpretive practices employed by core authors contradict the genre’s value base and function to silence and appropriate challenging empirical elements to affirm LPT’s valued interpretive schema. The author draws out deeply problematic implications of such appropriation through highlighting parallels between interpretation, appropriation, and colonization. The author ends by considering the nature of, and possibility for, more ethical “critical” interpretive organizational research.

Attack vectors against social networking systems : the Facebook example

Social networking systems (SNS’s) such as Facebook are an ever evolving and developing means of social interaction, which is not only being used to disseminate information to family, friends and colleagues but as a way of meeting and interacting with "strangers" through the advent of a large number of social applications. The attractiveness of such software has meant a dramatic increase in the number of frequent users of SNS’s and the threats which were once common to the Internet have now been magnified, intensified and altered as the potential for criminal behaviour on SNS’s increases. Social networking sites including Facebook contain a vast amount of personal information, that if obtained could be used for other purposes or to carry out other crimes such as identity theft. This paper will focus on the security threats posed to social networking sites and gain an understanding of these risks by using a security approach known as “attack trees”. This will allow for a greater understanding of the complexity associated with protecting Social Networking systems with a particular focus on Facebook.

Locating the semiotic power of multimodality

This article reports research that attempts to characterize what is powerful about digital multimodal texts. Building from recent theoretical work on understanding the workings and implications of multimodal communication, the authors call for a continuing empirical investigation into the roles that digital multimodal texts play in real-world contexts, and they offer one example of how such investigations might be approached. Drawing on data from the practice of multimedia digital storytelling, specifically a piece titled “Lyfe-N-Rhyme,” created by Oakland, California, artist Randy Young (accessible at http://www.oaklanddusty.org/videos.php), the authors detail the method and results of a fine-grained multimodal analysis, revealing semiotic relationships between and among different, copresent modes. It is in these relationships, the authors argue, that the expressive power of multimodality resides.

Video capture : pre-service teacher reflection, assessment or both

This paper reports on a small trial with 6 pre-service teachers who videoed their own teaching practices. The pre-service teachers used the tool to reflect on practice and to enhance their own understandings of themselves as teachers. The initial footage was used to by the pre-service teachers to gauge quite specific elements of their teaching: for example, were they asking effective questions, or were they responding appropriately to questions children asked and as always, what management strategies seemed to be working? Critical feedback from other students was initially „less than critical‟, but again over time, this also appeared to sharpen as they had more opportunity to use the technology. Initial embarrassment of being on screen was replaced with a professional approach to seeing the video as a tool for providing the opportunity to systematically deconstruct practices and for providing concrete feedback for improvement. Used in conjunction with teaching preparation courses, the videoed segments of teaching practice could be used to highlight exemplars, to show what actually happens in classrooms and to explain certain practices. Cunningham and Benedetto (2002) state “Recent developments in digital video technologies permit teacher candidates to collect, review, and manipulate video to demonstrate their growth as a professional and as a reflective practitioner.” However, in the development of the trial, the issue was raised by the pre-service teachers that they would be interested in keeping the videos as evidence of their teaching competence to be used in applications for teaching positions. In the small trial, ethics permission had not been gained for that to happen, but it is certainly a valid and viable possibility for the future. Currently prospective employers have to rely on paper applications which respond to selection criteria, evidence from pre-service teachers‟ teaching rounds and the subjective impressions of an interview. If students were able to present a 5 minute segment of them teaching, it might count for much more than any other evidence. Video capture of teaching practice would provide potential employers with an indication of a pre-service teacher‟s management strategies, relationships with children and a snapshot of a pre-service teacher‟s instructional practice. The idea of video-capture as a tool for pre-service teachers to illustrate teaching capabilities will be more fully investigated in this paper.
