A distinct cultural economy has emerged at Byron Bay in Far North Coast, New South Wales, Australia, which builds on connections between tourism and the production and marketing of music. Counter-urban migration and tourism have contributed to transformations of regional identity, as the Far North Coast is increasingly ...

PETI-375 was prepared using 2,3,3',4'- biphenyltetracarboxylic dianhydride (a-BPDA), 1,3-bis(4-aminophenoxy)benzene and 2,2'- bis(trifluoromethyl)benzidine and endcapped with 4-phenylethynylphthalic anhydride. This material exhibited a stable melt viscosity of 0.1-0.4 Pa·sec at 280°C.

Recent reports on holey graphene showed that holey 2D nanosheets can outperform their intact counterparts in many potential applications such as energy storage, catalysis, sensing, transistors, and molecular transport/separation. From both fundamental and application perspectives, it is desirable to obtain holey 2D nanosheets with defined hole morphology and hole edge structures. This remains a great challenge for graphene and is little explored for other 2D nanomaterials. Here, a facile, controllable, and scalable method is reported to carve geometrically defined pit/hole shapes and edges on hexagonal boron nitride (h-BN) basal plane surfaces via oxidative etching in air using silver nanoparticles as catalysts. The etched h-BN was further purified and exfoliated into nanosheets that inherited the hole/edge structural motifs and, under certain conditions, possess altered optical bandgap properties likely induced by the enriched zigzag edge atoms. This method opens up an exciting approach to further explore the physical and chemical properties of hole- and edge-enriched boron nitride and other 2D nanosheets, paving the way toward applications that can take advantage of their unique structures and performance characteristics.

People with an ASD have high levels of anxiety and a range of behaviours that create challenges for family carers. Interviews with forty carers in Sydney reveal how disruptive behaviours, including being noisy, hyperactive, obsessive and controlling, are very demanding for all carers. Carers have adapted home spaces, restricted and reduced patterns of employment and socialisation, and sometimes avoided the home, altering relationships between parents and other siblings. Home care for people with ASD has reduced the sense of home as a place of relaxation peace and stability, and, while providing a more caring environment for people with ASD, has contributed to the partial institutionalisation of the home.

The rationale for migration has been linked to numerous factors relating to the economies and health systems of source and destination countries. The contemporary migration of health workers is also embedded in a longstanding and intensifying culture of migration, centred on the livelihoods of extended households, and a medical culture that is oriented to superior technology and advanced skills. This dual culture is particularly evident in small island states in the Pacific, but is apparent in other significant migrant source countries in the Caribbean, Sub-Saharan Africa and Asia. Family expectations of the benefits of migration indicate that regulating the migration and attrition of health workers necessitates more complex policies beyond those evident within health care systems alone.

We present a dynamic programming approach for optimizing the codon selection for a given sequence of amino acids. The proposed approach is very efficient in that its mathematical analysis is easily tractable, its computer implementation is much simpler, and its overall complexity requires much less computational effort in comparison with one of the most recently developed methods for codon optimization.

Despite this, there are few longitudinal studies of any great depth and sophistication in the region. The contributors to this book have all conducted long-term research in the islands of the Pacific. During their visits and revisits they have witnessed first-hand the many changes that have occurred in their fieldsites as well as observing elements of continuity. They bring to their accounts a sense of their surprise at some of the unexpected elements of stability and of transformation. The authors take a range of disciplinary approaches, particularly geography and anthropology, and their contributions reflect their deep knowledge of Pacific places, some first visited more than 40 years ago. Many of the chapters focus on aspects of socio-economic change and continuity, while others focus on specific issues such as the impact of both internal and international migration, political and cultural change, technological innovation and the experiences of children and youth. By focusing on both change and continuity this collection of 11 case studies shows the complex relationships between Pacific societies and processes of ‘modernity’ and globalisation. By using a long-term lens on particular places, the authors are able to draw out the subtleties of change and its impacts, while also paying attention to what, in the contemporary Pacific, has been left remarkably unchanged. Filling a gap in the studies of the Pacific region, this book will appeal to an interdisciplinary audience in the fields of anthropology, development, geography, and Asia-Pacific studies.

This paper seeks to ascertain whether (and how) the COVID-19 pandemic might disrupt or reinforce existing patterns of doctor emigration. Method: This paper draws on qualitative interviews with 31 hospital doctors in Ireland, undertaken in June-July 2020. As the researchers were subject to a government mandated work-from-home order at that time, they utilised Twitter ™ to contact potential respondents (snowball sampling); and conducted interviews via Zoom ™ or telephone. Findings: Two cohorts of doctors were identified; COVID Returners (N = 12) and COVID Would-be Emigrants (N = 19). COVID Returners are Irish-trained emigrant doctors who returned to Ireland in March 2020, just as global travel ground to a halt. They returned to be closer to home and in response to a pandemic-related recruitment call issued by the Irish government. COVID Would-be Emigrants are hospital doctors considering emigration. Some had experienced pandemic-related disruptions to their emigration plans as a result of travel restrictions and border closures. However, most of the drivers of emigration mentioned by respondents related to underlying problems in the Irish health system rather than to the pandemic, i.e. a culture of medical emigration, poor working conditions and the limited availability of posts in the Irish health system. Discussion/conclusion: This paper illustrates how the pandemic intensified and reinforced, rather than radically altered, the dynamics of doctor emigration from Ireland. Ireland must begin to prioritise doctor retention and return by developing a coherent policy response to the underlying drivers of doctor emigration.
