Identity-Based Traitor Tracing With Short Private Key And Short Ciphertext, Fuchun Guo, Yi Mu, Willy Susilo

Faculty of Informatics - Papers (Archive)

Identity-based traitor tracing (IBTT) scheme can be utilized to identify a private (decryption) key of any identity that is illegally used in an identity-based broadcast encryption scheme. In PKC'07, Abdalla et al. proposed the first IBTT construction with short private key. In CCS'08, Boneh and Naor proposed a public-key traitor tracing, which can be extended to IBTT with short ciphertext. With a further exploration, in this paper, we propose the first IBTT with short private key and short ciphertext. Private key and ciphertext are both order of O(l 1+l 2), where l 1 is the bit length of codeword of …

Earth Is (Mostly) Flat: Apportionment Of The Flux Of Continental Sediment Over Millennial Time Scales, Jane K. Willenbring, Alexandru T. Codilean, Brandon Mcelroy

Faculty of Science, Medicine and Health - Papers: part A

We use a new compilation of global denudation estimates from cosmogenic nuclides to calculate the apportionment and the sum of all sediment produced on Earth by extrapolation of a statistically significant correlation between denudation rates and basin slopes to watersheds without denudation rate data. This robust relationship can explain approximately half of the variance in denudation from quartz-bearing topography drained by rivers using only mean slopes as the predictive tool and matches a similar fit for large river basins. At slopes >200 m/km, topography controls denudation rates. Controls on denudation in landscapes where average slopes are 10 mm/k.y. We use …

Synthesis Of Mn3o4-Encapsulated Graphene Sheet Nanocomposites Via A Facile, Fast Microwave Hydrothermal Method And Their Supercapacitive Behaviour, Li Li, Kuok Hau Seng, Zhixin Chen, Hua-Kun Liu, Ivan P. Nevirkovets, Zaiping Guo

Faculty of Engineering and Information Sciences - Papers: Part A

Well-crystallized Mn3O4-anchored reduced graphene oxide (rGO) nanocomposites have been successfully synthesized via a facile, effective, energy-saving, and scalable microwave hydrothermal technique for potential application as supercapacitor material. Integrating these nanostructures resulted in a strong synergistic effect between the two materials, consequently leading to a hybrid composite with higher specific capacitance compared to the bare Mn3O4 nanoparticles. The results from different sorts of characterization indicate that the Mn3O4 particles were deposited and anchored on graphene sheets. The capacitance value of the rGO(31.6%)–Mn3O4 nanocomposite reached 153 F/g, much higher than that of the bare Mn3O4 (87 F/g) at a scan rate of …

Taking Responsibility For Academic Integrity: A Collaborative Teaching And Learning Design, Julianne East, Lisa Donnelly

Journal of University Teaching & Learning Practice

La Trobe University, like many Australian universities, states that it values honest academic endeavour (Academic Integrity Policy 2011), and it can provide examples of good teaching practice in the areas of academic integrity, proper acknowledgment and avoiding plagiarism. Rather than relying on the chance that individuals will just develop good practices, this university has recently taken a more systematic approach to teaching students and staff about academic integrity and providing resources to ensure a consistent message and application of acknowledgment conventions. This systematic approach was made possible through the University’s curriculum reform program, the Design for Learning. By positioning academic …

Editorial 9.3, Tai Peseta

Journal of University Teaching & Learning Practice

This Special Edition of JUTLP is unique in that it examines a single university's approach to curriculum reform, providing insights from many of the people who were engaged in the process.

At La Trobe University in Australia the mechanism for engaging in discussions at a university level has been encapsulated in an institutional strategy known as Design for Learning (DfL) (La Trobe University 2009). From 2007, former Deputy Vice-Chancellor (Academic) Belinda Probert and former Pro Vice-Chancellor (Curriculum and Academic Planning) Tom Angelo, led an exciting and edgy curriculum change initiative intended to build on La Trobe’s learning and teaching strengths, …

High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer

Faculty of Science, Medicine and Health - Papers: part A

We investigated the muscle structure–function relationships that underlie the aerobic capacity of an insectivorous, small (~15 g) marsupial, Sminthopsis crassicaudata (Family: Dasyuridae), to obtain further insight into energy use patterns in marsupials relative to those in placentals, their sister clade within the Theria (advanced mammals). Disparate hopping marsupials (Suborder Macropodiformes), a kangaroo (Macropus rufus) and a rat-kangaroo (Bettongia penicillata), show aerobic capabilities as high as those of ‘athletic’ placentals. Equivalent muscle mitochondrial volumes and cardiovascular features support these capabilities. We examined S. crassicaudata to determine whether highly developed aerobic capabilities occur elsewhere in marsupials, rather than being restricted to the …

2-Cyanoethyl N,N,N',N'-Tetraisopropylphosphorodiamidite, Jichao Zhang

Faculty of Science, Medicine and Health - Papers: part A

2-Cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite is a colorless viscous liquid, which is soluble in most organic solvents. It is a widely used phosphitylating reagent for the preparation of various phosphorylated biomolecules, such as nucleoside carbohydrate conjugates, phospholipids and glycopeptides. In particular, this reagent is highly effective for automated solid-phase DNA/RNA oligonucleotide synthesis. 2-Cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite has shown great utility in the coupling of nucleobases or carbohydrates via their phosphotriesters in the presence of activators such as 1H-tetrazole, in moderate yields under mild conditions. Additionally, 2-cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite is cheaper and more stable than 2- cyanoethyl N,N-diisopropylchlorophosphorodiamidite, the other commonly used phosphinylating reagent. 2-Cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite is …

Privacy Issues And Solutions In Social Network Sites, Xi Chen, Katina Michael

Associate Professor Katina Michael

The boom of the internet and the explosion of new technologies have brought with them new challenges and thus new connotations of privacy. Clearly, when people deal with e-government and e-business, they do not only need the right to be let alone, but also to be let in secret. Not only do they need freedom of movement, but also to be assured of the secrecy of their information. Solove [6] has critiqued traditional definitions of privacy and argued that they do not address privacy issues created by new online technologies. Austin [7] also asserts: “[w]e do need to sharpen and …

A Molecular Survey Of Ulva (Chlorophyta) In Temperate Australia Reveals Enhanced Levels Of Cosmopolitanism, Lisa Kirkendale, Gary W. Saunders, Pia C. Winberg Dr

Shoalhaven Marine & Freshwater Centre

The green algal genus Ulva includes a speciose group of marine macroalgae inhabiting shallow seas worldwide. Although algal blooms in Asia highlight the opportunistic nature of several “nuisance” species, recent research clearly reveals important positive benefits of Ulva. Applied research requires accurate, reliable, and rapid identification, however, identification of Ulva spp. has met with con-siderable difficulty. Consequently, many have turned to molecular markers to aid in taxonomy. Previous studies of plants and algae have relied heavily on ITS and rbcL. Recently, tufA has been presented as a suitable barcoding gene to facilitate species-level identification of green macroalgae and it is …

The Gladiatorial Combat: Using An Arena Metaphor In Social And Environmental Accounting Research, Yanwen Shao, Corinne Cortese, Lee C. Moerman

11th Australasian Centre for Social and Environmental Accounting Research (A-CSEAR) Conference

Metaphors have been utilised in qualitative research as a theoretical frame. The use of an arena invokes the contested nature of social and environmental issues and the role of resources in decision-making and negotiation. However, as with all metaphors, certain interests are highlighted and others are obscured. Consideration of the arena and the associated characteristics of a ‘battle’ serve to privilege a worldview where power and access to resources dominate in contrast to the Habermasian ideal of open critical enquiry and different dimensions of reality.

Socially Responsible Investment In Malaysia: Behavioural Framework In Evaluating Investors’ Decision Making Process, Ainul Azreen Adam, Elvia Shauki

11th Australasian Centre for Social and Environmental Accounting Research (A-CSEAR) Conference

Socially responsible investment (SRI) represents the method of investment that consider the impact (good or bad) of investment decisions on social, ethics, and/or environment within the context of rigorous financial analysis. Despite the evidence of an increasing interest among academics and industry players on SRI, the understanding of the psychological aspect of decision-making behaviour of SRI investors is still incomplete. Currently, no published evidence has been found in the context of Malaysian investors‘ decision – making behaviour regarding SRI. Thus, this study aims to examine the role of intention, attitude, subjective norms, perceived behavioural control and moral norm in explaining …

Accounting, Public Policy, And The Hegemony Of 'Cost': The Framing Of Prison Privatisation In Nsw, Jane Andrew, Damien Cahill

11th Australasian Centre for Social and Environmental Accounting Research (A-CSEAR) Conference

As a practice, accounting has a sustained public image as a neutral communicative technology that is designed to objectively reflect underlying financial ‘realities’. Despite attempts by critical accounting researchers to challenge this image and to highlight the strategic power of accounting it has continued to provide a rationality that remains substantially unchallenged when mobilised within public policy debates. Accounting has a powerful presence within public policy discussions and is now largely accepted as the central framework within which policy should be formed. In order to explore the role of accounting information public policy and more particularly within policy discussions around …

Accountants are supportive of involvement in sustainability reporting but their actual involvement differs significantly from …

Critical Reflections On Laughlin’S ‘Middle Range Research Approach’: Language Not Mysterious?, Glen Lehman

11th Australasian Centre for Social and Environmental Accounting Research (A-CSEAR) Conference

Professor Richard Laughlin is renowned for applying critical insights from the German philosopher, Jurgen Habermas. His middle-range work has explored many accounting problems such as public-private partnerships, health care reforms and how accounting impacts cultural issues. Laughlin’s work re-conceptualises accountability in terms of cultural analysis, language and systems theory. Users of his work may encounter issues associated with: (1) understanding how to judge assertoric statements concerning various truth claims; (2) exploring the separation between the secular and sacred: and (3) examining whether language simply designates meaning or opens us to interpretive new pathways.
