Indigenous Australian visual art is an outstanding case of the dynamics of globalization and its intersection with the hyper-local wellsprings of cultural expression, and of the strengths and weaknesses of state, philanthropic and commercial backing for cultural production and dissemination. The chapter traces the development of the international profile of Indigenous ‘dot’ art – a traditional symbolic art form from the Western Desert – as ‘high-end’ visual art, and its positioning within elite markets and finance supported by key international brokers, collectors and philanthropists.

This chapter presents a novel control strategy for trajectory tracking of underwater marine vehicles that are designed using port-Hamiltonian theory. A model for neutrally buoyant underwater vehicles is formulated as a PHS, and then the tracking controller is designed for the horizontal plane-surge, sway and yaw. The control design is done by formulating the error dynamics as a set-point regulation port-Hamiltonian control problem. The control design is formulated in two steps. In the first step, a static-feedback tracking controller is designed, and the second step integral action is added. The global asymptotic stability of the closed loop system is proved and the performance of the controller is illustrated using a model of an open-frame offshore underwater vehicle.

Purpose Pharmaceuticals have played an important role in improving the quality of life of the human population in modern times. However, it must also be acknowledged that both the production and use of pharmaceuticals have a significant, negative impact on the environment and consequently, a negative impact on the health of humans and wildlife. This negative impact is due to the embedded carbon in pharmaceuticals' manufacture and distribution and the waste generated in their manufacture, consumption and disposal. Pharmaceutical waste is comprised of contaminated waste (unwanted pharmaceuticals and their original containers) and non-contaminated waste (non-hazardous packaging waste). The paper aims to discuss these issues. Design/methodology/approach The article is a literature review. Findings The article identified a gap in the literature around pharmacist attitudes and behaviour toward the environmentally responsible handling of pharmaceutical waste. Originality/value Pharmacists, with their professional commitment to the quality use of medicines and their active participation in the medicines management pathway, already play an important role in the more sustainable use of pharmaceuticals. Even so, they have the potential to play an even greater role with the environmentally responsible disposal of pharmaceutical waste (including packaging waste) and the education of other health professionals and the general public on this topic.

This study seeks to fill in gap in the existing literature by looking at how and whether disclosure of social value creation becomes a part of legitimation strategies of social enterprises. By using legitimacy reasoning, this study informs that three global social organizations, Grameen Bank, Charity Water, and the Bill and Melinda Gates Foundation provide evidence of the use of disclosures of social value creation in order to conform with the expectations of the broader community—the community that wants to see poverty and injustice free world.

As we stand at the beginning of the 21st century and behold the world before us, it seems that we are living in a time of profound change. Everywhere we look change seems afoot, demolishing our traditional securities and hastily building new ones in their place. Modern medical science has been an integral part of this change. It is not possible to ignore the advances of modern medicine nor the realities of scientific uncertainties for they are part of the shared context of our lives today. I In the past 50 years we have witnessed the discovery of DNA and more recently the mapping of the human genome, the birth of the world's first in-vitro fertilisation baby, followed by thousands worldwide in the period since, the discovery of human stem cells and the birth of Dolly the cloned sheep in Scotland. Furthermore, the processes of globalisation have ensured that an event that occurs on one side of the globe becomes an item on the evening news on the other side, creating the impression that all change takes place on our doorstep. Some of these events have provoked deep angst in the community, sparking public debate over the ethics of science and the boundaries to be imposed by law. All of these developments have changed the realm of the possible. While these advances in medical science spark debate in the developed countries, in less developed countries high rates of infectious diseases and infant and maternal mortality and the challenges of access to adequate food and clean water are priorities, highlighting international differences in health care. This article explores these differences through an analysis of globalisation and reproduction. It seeks to analyse both the meaning of globalisation and the impact of globalising trends on health laws and policies as regulators of women's health within the global village.

In 2004 the International Committee of Medical Journal Editors (ICMJE) issued a statement indicating that from 1 July 2005 registration in a publicly accessible trials registry would be a condition of publication in an ICMJE member journal. The World Health Organisation is coordinating the International Clinical Trials Registry Platform (ICTRP) as a means of providing a standardised framework for registration. This article considers the practical challenges and opportunities that arise from these developments and considers the relevance of trial registration for women and minorities and for developing countries.

Within contemporary society the themes of globalization, health and regulation interlock in complex patterns, changing in response to the mix of cultural differences, regulatory preferences and available resources. To turn the kaleidoscope and to change the mix is to change the pattern. This book is about those patterns as they arise in the contemporary legal, health and ethical context, exploring the transformations and challenges brought by technological change and the regulatory options in the contemporary global village.

Ramp signalling is an access control for motorways, in which a traffic signal is placed at on-ramps to regulate the rate of vehicles entering the motorway and thus to preserve the motorway capacity. In general, ramp signalling algorithms fall into two categories: local control and coordinated control by their effective scope. Coordinated ramp signalling strategies make use of measurements from the entire motorway network to operate individual ramp signals for the optimal performances at the network level. This study proposes a multi-hierarchical strategy for coordinated ramp signalling. The strategy is structured in two layers. At the higher layer with a longer update interval, coordination group is assembled and disassembled based on the location of high-risk breakdown flow. At the lower layer with a shorter update interval, individual ramps are hired to serve the coordination and are also released based on the prevailing congestion level on the ramp. This strategy is modelled and applied to the northbound Pacific Motorway micro-simulation platform (AIMSUN). The simulation results show an effective congestion mitigation of the proposed strategy.

This paper presents a novel control strategy for trajectory tracking of marine vehicles manoeuvring at low speed. The model of the marine vehicle is formulated as a Port-Hamiltonian system, and the tracking controller is designed using energy shaping and damping assignment. The controller guarantees global asymptotic stability and includes integral action for output variables with relative degree greater than one.

Recently, the capture and storage of CO2 have attracted research interest as a strategy to reduce the global emissions of greenhouse gases. It is crucial to find suitable materials to achieve an efficient CO2 capture. Here we report our study of CO2 adsorption on boron-doped C60 fullerene in the neutral state and in the 1e−-charged state. We use first principle density functional calculations to simulate the CO2 adsorption. The results show that CO2 can form weak interactions with the BC59 cage in its neutral state and the interactions can be enhanced significantly by introducing an extra electron to the system.

Many cognitive neuroscience studies show that the ability to attend to and identify global or local information is lateralised between the two hemispheres in the human brain; the left hemisphere is biased towards the local level, whereas the right hemisphere is biased towards the global level. Results of two studies show attention-focused people with a right ear preference (biased towards the left hemisphere) are better at local tasks, whereas people with a left ear preference (biased towards the right hemisphere) are better at more global tasks. In a third study we determined if right hemisphere-biased followers who attend to global stimuli are likely to have a stronger relationship between attention and globally based supervisor ratings of performance. Results provide evidence in support of this hypothesis. Our research supports our model and suggests that the interaction between attention and lateral preference is an important and novel predictor of work-related outcomes.

The objective of this experimental study is to capture the dynamic temporal processes that occur in changing work settings and to test how work control and individuals' motivational predispositions interact to predict reactions to these changes. To this aim, we examine the moderating effects of global self-determined and non-self-determined motivation, at different levels of work control, on participants' adaptation and stress reactivity to changes in workload during four trials of an inbox activity. Workload was increased or decreased at Trial 3, and adaptation to this change was examined via fluctuations in anxiety, coping, motivation, and performance. In support of the hypotheses, results revealed that, for non-self-determined individuals, low work control was stress-buffering and high work control was stress-exacerbating when predicting anxiety and intrinsic motivation. In contrast, for self-determined individuals, high work control facilitated the adaptive use of planning coping in response to a change in workload. Overall, this pattern of results demonstrates that, while high work control was anxiety-provoking and demotivating for non-self-determined individuals, self-determined individuals used high work control to implement an adaptive antecedent-focused emotion regulation strategy (i.e., planning coping) to meet situational demands. Other interactive effects of global motivation emerged on anxiety, active coping, and task performance. These results and their practical implications are discussed.
