Competition laws and policies in China and Hong Kong : a tale of two regulatory journeys

Reviews the background to China's enactment of the Anti-Monopoly Law in 2007 and compares the debate surrounding the proposed introduction of similar legislation in Hong Kong. Examines the main issues arising during the Law's 13 year drafting stage, its key provisions and the remaining areas of uncertainty concerning its enforcement. Discusses ongoing efforts to introduce competition law regulations in Hong Kong, the main features of the draft General Competition Law and the shortcomings of its approach to penalties and exemptions.

The culture of the Christian school

In discussions of educational administration theory, school culture has emerged as a contentious construct characterized by polarized positions. The underlying tensions are between conflicting structuralist and post-structuralist perspectives. These have led to views of Christian school culture and school organization as being either, on the one hand, static, positivist, hierarchical, individualistic and capitalistic or, on the other, dynamic, coherentist, communally interdependent, service oriented and Christ-centered. All schools demonstrate an ethos or organizational culture by default if not by design. It is therefore imperative for Christian school administrators, educators, and the community to consciously define the aspects of school culture that reflect the shared biblical values of the Christian school community.

Assessing the vulnerability of eco-environmental health to climate change

There is an urgent need to assess the vulnerability of eco-environmental health to climate change. This paper aims to provide an overview of current research, to identify knowledge gaps, and to propose future research needs in this challenging area. Evidence shows that climate change is affecting and will, in the future, have more (mostly adverse) impacts on ecosystems. Ecosystem degradation, particularly the decline of the life support systems, will undoubtedly affect human health and wellbeing. Therefore, it is important to develop a framework to assess the vulnerability of eco-environmental health to climate change, and to identify appropriate adaptation strategies to minimize the impact of climate change.

Plantar enthesopathy : thickening of the enthesis is correlated with energy dissipation of the plantar fat pad during walking

Background: The enthesis of the plantar fascia is thought to play an important role in stress dissipation. However, the potential link between entheseal thickening characteristic of enthesopathy and the stress-dissipating properties of the intervening plantar fat pad have not been investigated. Purpose: This study was conducted to identify whether plantar fat pad mechanics explain variance in the thickness of the fascial enthesis in individuals with and without plantar enthesopathy. Study Design: Case-control study; Level of evidence, 3. Methods: The study population consisted of 9 patients with unilateral plantar enthesopathy and 9 asymptomatic, individually matched controls. The thickness of the enthesis of the symptomatic, asymptomatic, and a matched control limb was acquired using high-resolution ultrasound. The compressive strain of the plantar fat pad during walking was estimated from dynamic lateral radiographs acquired with a multifunction fluoroscopy unit. Peak compressive stress was simultaneously acquired via a pressure platform. Principal viscoelastic parameters were estimated from subsequent stress-strain curves. Results: The symptomatic fascial enthesis (6.7 ± 2.0 mm) was significantly thicker than the asymptomatic enthesis (4.2 ± 0.4 mm), which in turn was thicker than the enthesis (3.3 ± 0.4 mm) of control limbs (P < .05). There was no significant difference in the mean thickness, peak stress, peak strain, or secant modulus of the plantar fat pad between limbs. However, the energy dissipated by the fat pad during loading and unloading was significantly lower in the symptomatic limb (0.55 ± 0.17) when compared with asymptomatic (0.69 ± 0.13) and control (0.70 ± 0.09) limbs (P < .05). The sonographic thickness of the enthesis was correlated with the energy dissipation ratio of the plantar fat pad (r = .72, P < .05), but only in the symptomatic limb. Conclusion: The energy-dissipating properties of the plantar fat pad are associated with the sonograpic appearance of the enthesis in symptomatic limbs, providing a previously unidentified link between the mechanical behavior of the plantar fat pad and enthesopathy.

Managing process model complexity via concrete syntax modifications

While Business Process Management (BPM) is an established discipline, the increased adoption of BPM technology in recent years has introduced new challenges. One challenge concerns dealing with the ever-growing complexity of business process models. Mechanisms for dealing with this complexity can be classified into two categories: 1) those that are solely concerned with the visual representation of the model and 2) those that change its inner structure. While significant attention is paid to the latter category in the BPM literature, this paper focuses on the former category. It presents a collection of patterns that generalize and conceptualize various existing mechanisms to change the visual representation of a process model. Next, it provides a detailed analysis of the degree of support for these patterns in a number of state-of-the-art languages and tools. This paper concludes with the results of a usability evaluation of the patterns conducted with BPM practitioners.

Project alliancing Vs project partnering : a case study of the Australian National Museum project

Significant differences between project partnering and project alliancing occur in the selection process, management structure of the organisations undertaking the project and nature of risk and reward incentives. This paper helps clarify the nature of project alliancing and how alliance member organisations were selected for this case study. A core issue that differentiates between the two approaches is that in partnering, partners may reap rewards at the expense of other partners. In alliancing each alliance member places their profit margin and reward structure ÁÁat riskÂÂ. Thus in alliancing, the entire alliance entity either benefits together or not all. This fundamentally changes the motivation and dynamics of the relationship between alliance members.

Barrow Island's biosecurity : catching the unknown invader

When industry meets a conservation area, animals or plants from outside may hitch a lift and potentially wreak havoc. How can you be sure of catching the intruders – or at least 80% sure? A government directive instructed Frith Jarrad, Peter Whittle, Susan Barrett and Kerrie Mengersen to come up with a statistically measurable scheme.

Arts-based research in design education

There is an urgent need in terms of changing world conditions to move beyond the dualist paradigm that has traditionally informed design research, education and practice. Rather than attempt to reduce uncertainty, novelty and complexity as is the conventional approach, an argument is presented in this article that seeks to exploit these qualities through a reconceptualisation of design in creative as well as systematic, rigorous and ethical terms. Arts-based research, which 'brings together the systematic and rigorous qualities of inquiry with the creative and imaginative qualities of the arts', is presented as being central to this reconceptualisation. This is exemplified in the application of art-informed inquiry in a research unit for graduating tertiary-level interior design students. The application is described in this article and is shown to rely substantially on the image and its capacity to open up and reveal new possibilities and meaning.

Parliamentary inquiry into alcohol-related violence

Alcohol consumption has been a popular leisure activity among Australian since European Settlement. Australians currently consume 7.2 litres per capita pure alcohol and Australia in regards to alcohol consumption is ranked as the 22nd highest country of 58 countries. Although the alcohol industry has provided leisure, employment and government taxes, alcohol use has also become associated with chronic health problems, crime, public disorder and violence. Drunken and disorderly behaviour is commonly associated with Pubs, Clubs and Hotels, particularly in the late night entertainment areas. Historically, drunkenness and disorderly behaviour has been managed by measures such as floggings, jail and treatment in asylums. Alcohol has also been banned in specific areas and restrictions have applied to hours and days of operation. In more recent times alcohol policies have included extended trading hours, restricted trading hours and bans in some Aboriginal communities in order to reduce alcohol-related violence. Community and business partnerships in and around licensed premises have also developed in order to address the noise, violence and disorderly behaviour that often occurs in the evenings and early mornings. There is an urgent need for the government to be more robust about implementing effective alcohol control policies in order to prevent and reduce the harmful effects of alcohol.

Investigation of electrophoretic loading and enhanced mechanical properties of hydrogels for delivery of therapeutic proteins

Hydrogels, which are three-dimensional crosslinked hydrophilic polymers, have been used and studied widely as vehicles for drug delivery due to their good biocompatibility. Traditional methods to load therapeutic proteins into hydrogels have some disadvantages. Biological activity of drugs or proteins can be compromised during polymerization process or the process of loading protein can be really timeconsuming. Therefore, different loading methods have been investigated. Based on the theory of electrophoresis, an electrochemical gradient can be used to transport proteins into hydrogels. Therefore, an electrophoretic method was used to load protein in this study. Chemically and radiation crosslinked polyacrylamide was used to set up the model to load protein electrophoretically into hydrogels. Different methods to prepare the polymers have been studied and have shown the effect of the crosslinker (bisacrylamide) concentration on the protein loading and release behaviour. The mechanism of protein release from the hydrogels was anomalous diffusion (i.e. the process was non-Fickian). The UV-Vis spectra of proteins before and after reduction show that the bioactivities of proteins after release from hydrogel were maintained. Due to the concern of cytotoxicity of residual monomer in polyacrylamide, poly(2-hydroxyethyl- methacrylate) (pHEMA) was used as the second tested material. In order to control the pore size, a polyethylene glycol (PEG) porogen was introduced to the pHEMA. The hydrogel disintegrated after immersion in water indicating that the swelling forces exceeded the strength of the material. In order to understand the cause of the disintegration, several different conditions of crosslinker concentration and preparation method were studied. However, the disintegration of the hydrogel still occurred after immersion in water principally due to osmotic forces. A hydrogel suitable for drug delivery needs to be biocompatible and also robust. Therefore, an approach to improving the mechanical properties of the porogen-containing pHEMA hydrogel by introduction of an inter-penetrating network (IPN) into the hydrogel system has been researched. A double network was formed by the introduction of further HEMA solution into the system by both electrophoresis and slow diffusion. Raman spectroscopy was used to observe the diffusion of HEMA into the hydrogel prior to further crosslinking by ã-irradiation. The protein loading and release behaviour from the hydrogel showing enhanced mechanical property was also studied. Biocompatibility is a very important factor for the biomedical application of hydrogels. Different hydrogels have been studied on both a three-dimensional HSE model and a HSE wound model for their biocompatibilities. They did not show any detrimental effect to the keratinocyte cells. From the results reported above, these hydrogels show good biocompatibility in both models. Due to the advantage of the hydrogels such as the ability to absorb and deliver protein or drugs, they have potential to be used as topical materials for wound healing or other biomedical applications.

Assessing the relationship between global warming and mortality : lag effects of temperature fluctuations by age and mortality categories

Although interests in assessing the relationship between temperature and mortality have arisen due to climate change, relatively few data are available on lag structure of temperature-mortality relationship, particularly in the Southern Hemisphere. This study identified the lag effects of mean temperature on mortality among age groups and death categories using polynomial distributed lag models in Brisbane, Australia, a subtropical city, 1996-2004. For a 1 °C increase above the threshold, the highest percent increase in mortality on the current day occurred among people over 85 years (7.2% (95% CI: 4.3%, 10.2%)). The effect estimates among cardiovascular deaths were higher than those among all-cause mortality. For a 1 °C decrease below the threshold, the percent increases in mortality at 21 lag days were 3.9% (95% CI: 1.9%, 6.0%) and 3.4% (95% CI: 0.9%, 6.0%) for people aged over 85 years and with cardiovascular diseases, respectively. These findings may have implications for developing intervention strategies to reduce and prevent temperature-related mortality.
