Hail to the thief: A tribute to Kazaa

This paper considers the ongoing litigation against the peer to peer network Kazaa. Record companies and Hollywood studios have faced jurisdictional and legal problems in suing this network for copyright infringement. As Wired Magazine observes: ’The servers are in Denmark. The software is in Estonia. The domain is registered Down Under, the corporation on a tiny island in the South Pacific. The users - 60 million of them - are everywhere around the world.' In frustration, copyright owners have launched copyright actions against intermediaries - like Internet Service Providers such as Verizon. They have also embarked on filing suits of individual users of file-sharing programs. In addition, copyright owners have called for domestic and international law reform in respect of digital copyright. The Senate Committee on Government Affairs in the United States Congress has reviewed the controversial use of subpoenas in suits against users of file-sharing peer to peer networks. The United States has encouraged other countries to adopt provisions of the Digital Millennium Copyright Act 1998 (US) in bilateral and regional free trade agreements.

Adaptive aneuploidy protects against thiol peroxidase deficiency by increasing respiration via key mitochondrial proteins

Aerobic respiration is a fundamental energy-generating process; however, there is cost associated with living in an oxygen-rich environment, because partially reduced oxygen species can damage cellular components. Organisms evolved enzymes that alleviate this damage and protect the intracellular milieu, most notably thiol peroxidases, which are abundant and conserved enzymes that mediate hydrogen peroxide signaling and act as the first line of defense against oxidants in nearly all living organisms. Deletion of all eight thiol peroxidase genes in yeast (∆8 strain) is not lethal, but results in slow growth and a high mutation rate. Here we characterized mechanisms that allow yeast cells to survive under conditions of thiol peroxidase deficiency. Two independent ∆8 strains increased mitochondrial content, altered mitochondrial distribution, and became dependent on respiration for growth but they were not hypersensitive to H2O2. In addition, both strains independently acquired a second copy of chromosome XI and increased expression of genes encoded by it. Survival of ∆8 cells was dependent on mitochondrial cytochrome-c peroxidase (CCP1) and UTH1, present on chromosome XI. Coexpression of these genes in ∆8 cells led to the elimination of the extra copy of chromosome XI and improved cell growth, whereas deletion of either gene was lethal. Thus, thiol peroxidase deficiency requires dosage compensation of CCP1 and UTH1 via chromosome XI aneuploidy, wherein these proteins support hydroperoxide removal with the reducing equivalents generated by the electron transport chain. To our knowledge, this is the first evidence of adaptive aneuploidy counteracting oxidative stress.

Race against time: The export of essential medicines to Rwanda

This article considers the significance of the first export of essential medicines under the WTO General Council Decision 2003. In July 2007, Rwanda became the first country to provide a notification under the WTO General Council Decision 2003 of its intent to import a fixed-dose, triple combination HIV/AIDS drug manufactured by the Canadian generic pharmaceuticalmanufacturer Apotex, Inc. In September 2007, Apotex was granted the first compulsory licence application under Canada's Access to Medicines Regime. This article considers the convoluted and protracted negotiations between the Government of Rwanda, Apotex and three patent holders, GlaxoSmithKline, Boehringer Ingleheim Canada and Shire BioChemical, Inc. It questions the efficiency of this process. This article considers the review of the Jean Chretien Pledge to Africa Act 2004 (Canada). It is critical of the refusal of the Conservative Government of Canada to make any amendments to the legislation to improve the cost-effective delivery of essential medicines. This article queries the proposed Hong Kong Amendment to the TRIPS Agreement 1994, given the concerns of the Africa Group. It is submitted that it is undesirable to codify the WTO General Council Decision 2003, given its failure to provide a speedy, efficient and cost-effective delivery of essential medicines.

Novel protective covering to enhance concrete resistance against projectile impact

A novel protective covering with a layered and staggered structure was proposed to protect concrete against projectile impact. Experimental study was conducted to investigate the ballistic behaviour of the concrete targets against 12.7 mm armour-piercing incendiary projectile at velocities ranging from 537.7 to 596.5 m/s. The results showed that the concrete targets with protective covering exhibited superior integrity with no damage on the distal surface, whereas the concrete targets without protective covering were fractured with penetrating cracks throughout the thickness of the target. Moreover, the protected concrete targets displayed significantly reduced penetration depth compared with the concrete targets without protective covering. The protective covering with epoxy adhesive interlayers had a bigger protection factor than that with silicone sealant interlayers, but the former suffered more severe damage than the latter.

Parametric study on cement-based soft-hard-soft (SHS) multi-layer composite pavement against blast load

An innovative cement-based soft-hard-soft (SHS) multi-layer composite has been developed for protective infrastructures. Such composite consists of three layers including asphalt concrete (AC), high strength concrete (HSC), and engineered cementitious composites (ECC). A three dimensional benchmark numerical model for this SHS composite as pavement under blast load was established using LSDYNA and validated by field blast test. Parametric studies were carried out to investigate the influence of a few key parameters including thickness and strength of HSC and ECC layers, interface properties, soil conditions on the blast resistance of the composite. The outcomes of this study also enabled the establishment of a damage pattern chart for protective pavement design and rapid repair after blast load. Efficient methods to further improve the blast resistance of the SHS multi-layer pavement system were also recommended.

Cytokine mRNA expression and IFN-γ production of immunised nematode resistant and susceptible lambs against natural poly-generic challenge

IL-2, IL-4 and IFN-γ mRNA expression, and production of IFN-γ was examined in mesenteric lymph node cells (MLNC) and CD4+ enriched T cell populations of nematode resistant (R) and susceptible (S) line lambs by use of RT-PCR and ELISA. Five R and S line lambs that were immunised by repeated oxfendazole-abbreviated infections and 5 non-immunised R and S line lambs were used. All lambs grazed nematode infected pasture for 107 days. Immunisation enhanced the resistant status in both R and S lambs. MLNC obtained from slaughtered animals were stimulated with Con A or T. colubriformis specific antigen. Non-stimulated MLNC of immunised lambs expressed higher levels of IL-4 mRNA and lower levels of IL-2 mRNA than non-immunised lambs. MLNC of immunised R and S line lambs stimulated with antigen for 24 h expressed detectable amounts of IL-4 mRNA that was not seen in non-immunised controls. CD4+ T cell enriched cell populations of immunised R and S lambs and non-immunised R lambs expressed moderate to high levels of IL-4 mRNA. Con A stimulated MLNC of immunised R and S lambs expressed high levels IFN-γ mRNA and produced high amounts of IFN-γ. Lower levels were present in non-immunised controls. The results indicate that R line lambs and immunised S line lambs respond to natural nematode challenge with a predominating IL-4 cytokine response when compared to non-immunised S lambs.

The political decisions and policy leading to the Royal Australian Air Force having no fighters or interceptors for the coming war against Japan

The thesis provides an understanding of the ignored need for a modern air defence system for the Australian air force to meet the growing threat from Japan in the 1930s and early 1940s. The quality of advice provided to, and accepted by, Australian politicians was misleading and eliminated the need for fighters and interceptors despite glaring evidence to the contrary. Based on primary source material, including official documents, Allied and Axis pilot memoirs, popular aviation literature and newspaper and magazine articles and interviews, the thesis highlights the inability of Australian politicians to face the reality of the international situation.

Violence against children in the Asia Pacific region: the situation is becoming clearer [Editorial]

Up to the year 2000, there was very little scientific evidence in this region about the scale of child maltreatment, its effects on children, families, and society, and the resultant economic burden. Since then, many agencies large and small, government and nongovernment, and universitybased researchers have worked independently with diverse groups of people to measure violence, neglect and other childhood adversities and to understand the harmful consequences...

Domestic reflections, electric reflections: Towards design interventions against everyday energy mundanity in the home

For many years, Human-Computer Interaction and interaction design researchers have been exploring the potential for interactive technologies to encourage sustainable living practices. This paper examines existing literature concerning domestic energy feedback, interlacing past examples of domestic interventions into the discussion. It synthesises recent design research conducted around domestic energy-use and provides a discussion into household circumstances, everyday activities, and the use and role of design. The themes presented are threefold. First, the individual is contrasted to the household collective and in turn calls for the scope and scale of design interventions to be geared towards connection between household members. The second theme questions the everyday, and proposes new avenues of thought when designing for the mundanity of everyday life. Finally, I propose that a design approach which counteracts an affirmative design approach, such as critical design, is an appropriate fit when critiquing and evaluating the mundane, everyday aspects of domestic life.

Medical negligence, causation and 'exceptional cases' under the civil liability legislation

Under the civil liability legislation enacted in most Australian jurisdictions, factual causation will be established if, on the balance of probabilities, the claimant can prove that the defendant's negligence was 'a necessary condition of the occurrence of the [claimant's] harm'. Causation will then be satisfied by showing that the harm would not have occurred 'but for' the defendant's breach of their duty of care. However, in an exceptional or appropriate case, sub-section 2 of the legislation provides that if the 'but for' test is not met, factual causation may instead be determined in accordance with other 'established principles'. In such a case, 'the court is to consider (amongst other relevant things) whether or not and why responsibility for the harm should be imposed' on the negligent party.

Regulating against corporate phoenix activity

This paper considers the adequacy and efficiency of existing legal and regulatory frameworks to deal with corporate phoenix activity. Phoenix activity, which is often triggered by a solvency crisis, is estimated to cost the Australian economy up to $3 billion each year. Despite the raft of piecemeal Australian legislation directed at this activity, phoenix activity does not appear to be abating. This paper considers regulatory approaches to detection and enforcement of the underlying law. This study reveals and explores a perception that the law is deficient, and the tension that exists between the adequacy of the law and the regulatory approach.

Protection of rabbits against lapinized rinderpest virus with purified envelope glycoproteins of peste-des-petits-ruminants and rinderpest viruses

Haemagglutinin (HA) and fusion (F) proteins of peste-des-petits-ruminants virus (PPRV) and rinderpest virus (RPV) were purified by immunoaffinity chromatography. The purified proteins were characterized by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS-PAGE). Rabbit hyperimmune sera were raised against the purified HA and F proteins and assayed by enzyme-linked immunosorbent assay (ELISA), haemagglutination-inhibition (HAI) and virus neutralization (VN) tests. The immunized animals were challenged with a virulent lapinized (rabbit-adapted) strain of RPV: Both HA and F proteins of PPRV protected rabbits against a lethal challenge with lapinized RPV. As expected, RPV HA and F proteins also conferred a similar protection against the homologous challenge. The postchallenge antibody responses were of a true anamnestic type.

Serum immunoglobulin G directed against porcine trypsin in the serum of cystic fibrosis children receiving porcine pancreatic enzyme supplements

Cystic fibrosis (CF) patients require pancreatic enzyme replacement therapy to correct pancreatic insufficiency. These enzymes are derived from porcine pancreas and are known to be antigenic. To determine the possible clinical consequences, a specific ELISA was developed to detect IgG antibody directed against porcine trypsin (PTAb) in the sera of CF patients. The assay was used to evaluate the occurrence of PTAb in a cross sectional study of 103 CF patients in relation to the introduction of porcine enzyme therapy, clinical status and genotype. Antibodies against porcine trypsin were detected in the sera of 63% of patients unrelated to the age of commencement or the duration of enzyme therapy. No differences were observed in the clinical status of CF patients who had developed PTAb (n = 65) and those who had no detectable PTAb (n = 38) as determined from: the current prescribed dose of porcine pancreatic enzyme capsules; Z scores for height and weight; and respiratory function tests. It is suggested that the PTAb commonly found in the sera of CF patients are of doubtful clinical significance but the prospect of PTAb contributing to immune complex disease should be examined further.

Implementation mechanism: Protection against harassment of women at workplace

Pakistan is widely known and appreciated in the world for its history, Islamic culture and norms. Since the creation of Pakistan, it inherited poverty in its roots. There are many reasons for poverty but one lies on the shoulder of women who are 50% of the total population of Pakistan. On the apex of it, women do not take part in the development of Pakistan because when they step out of their homes, they suffer a lot of problems. These problems are a hurdle in their active participation in development .Government has tried to create an environment for those women, who suffer different problems. Harassment of women at work place is one of those problems which discourage women in taking active part in economic and social development of society. Women Activists, from the last decade, were working for the protection of woman’s right at workplace and they succeeded in formulation of Harassment Act 2010. Since law is ineffective without its proper mechanism of implementation, steps should be taken for its proper implementation mechanism. This article aims to provide information about the provisions of law, related to the harassment of women at workplace with an attempt to explore the effectiveness of its implementation. The study was conducted in twin cities of Pakistan, Islamabad and Rawalpindi. Interviews were conducted with the employees and employers of organizations, educational institutions, women activists, NGOs workers, lawyers, judges and some law enforcement officers. Group discussions were also held with teachers, students of Human rights and religious personalities. This report focuses on the implementation mechanism of new legislation in Pakistan. It also highlights some important facts related to its enforcement.
