Phosphorus-Nitrogen Heterocycles Derived from Chelating N-Donor Ligands: Historical Advances, Recent Highlights, and Outlook.

The exploration of phosphorus-nitrogen heterocycles derived from chelating N-donor ligands is an area of research that has lagged behind the development of similar heterocycles based on other main group elements, most notably boron. The fact that phosphorus and nitrogen are both group 15 elements and that their compounds are most commonly viewed as Lewis bases likely contributes to this observation. However, through judicious ligand design and creative use of phosphorus sources that render phosphorus as Lewis acidic and/or electron poor, a variety of heterocyclic architectures are possible.

North American avian species that migrate in flocks show greater long-term non-breeding range shift rates.

Background: Many species are exhibiting range shifts associated with anthropogenic change. For migratory species, colonisation of new areas can require novel migratory programmes that facilitate navigation between independently-shifting seasonal ranges. Therefore, in some cases range-shifts may be limited by the capacity for novel migratory programmes to be transferred between generations, which can be genetically and socially mediated.

Ligand protonation leads to highly fluorescent boronium cations.

Fluorophores that respond to external stimuli, such as changes in pH, have utility in bio-imaging and sensing applications. Almost all pH-responsive fluorophores rely on complex syntheses and the use of pH-responsive functional groups that are peripheral to the fluorophore framework. In this work, pH-responsive boron-containing heterocycles based on tridentate acyl pyridylhydrazone ligands were prepared.

Organic Room Temperature Phosphorescence from BN-Substituted Xanthene Derivatives.

Emissive organic materials are predominantly fluorescent and there is significant interest in realizing and understanding examples that defy this paradigm and exhibit phosphorescence under ambient conditions. Organic room temperature phosphorescence (ORTP) offers the long-lived excited states and bathochromically-shifted emission maxima of phosphorescence without the use of potentially toxic and expensive transition metals. Most ORTP materials rely on well-studied structural motifs that include aryl carbonyls, sulfones, and heavy main group elements.

Platinum-Centered Oligoynes Capped by Boron Difluoride Formazanate Dyes and Their Thin-Film Properties.

Since the Nobel prize winning discovery that polyacetylene could act as a semiconductor, there has been tremendous efforts dedicated to understanding and harnessing the unusual properties of π-conjugated polymers. Much of this research has focused on the preparation of oligoynes and polyynes with well-defined numbers of repeating alkyne units as models for carbyne. These studies are usually hampered by a structure-property relationship where the stability of the resulting materials decrease with the incorporation of additional alkyne units.

Aboriginal families living with MJD in remote Australia: questions of access and equity.

Managing genetic disease using medically assisted reproductive technology is increasingly promoted as a feasible option, given revolutionary advances in genomics. Far less attention has been directed to the issue of whether there is equitable access to this option. Context and circumstance determine equitable access; however, reporting has drawn overwhelmingly from affluent Anglo-western populations in developed countries.

A scoping review of early childhood support for Aboriginal and Torres Strait Islander children living with a disability in regional, rural and remote settings.

Introduction: Many experts and communities have concerns about how National Disability Insurance Scheme services are provided to Aboriginal and Torres Strait children. This study was undertaken at the request of the NPY Women's Council in partnership with the researchers, to explore supports for Aboriginal and Torres Strait Islander children living with a disability in their remote areas.

Objective: This scoping review aims to (a) explore the barriers and enablers to accessing disability support services for families of young Aboriginal and Torres Strait Islander children (0-8 years) living in regional, rural and remote settings, and (b) summarise best practice approaches for accessing support for young children in these settings.

Accounting for imperfect detection when estimating species-area relationships and beta-diversity.

Ecologists have historically quantified fundamental biodiversity patterns, including species-area relationships (SARs) and beta diversity, using observed species counts. However, imperfect detection may often bias derived community metrics and subsequent community models. Although several statistical methods claim to correct for imperfect detection, their performance in species-area and β-diversity research remains unproven.

All hands on deck during the COVID-19 pandemic. Maintaining face-to-face medical education and clinical placements.

Medical students must have robust educational experiences, graduate and commence timely employment. Here, we describe how the Royal College of Surgeons in Ireland (RCSI) delivered clinical placements in medical programmes over the first three waves of the COVID-19 pandemic in Ireland, including a student-centred, holistic approach to students' educational, social and health needs with strong student involvement, re-organising the university's primary care team, developing COVID-19 PCR testing on site and re-focusing communications and student services. This resulted in re-arranging the students into learning communities, and students and staff electronically recorded their COVID-19 symptom status daily.

Movement of juvenile migratory birds from settlement to adulthood across the non-breeding range.

Among migratory vertebrates, high levels of fidelity to non-breeding sites during adulthood are common. If occupied sites vary in quality, strong site fidelity can have profound consequences for individual fitness and population demography. Given the prevalence of adult site fidelity, the regions of the non-breeding range to which juveniles first migrate, and the scale of any subsequent movements, are likely to be pivotal in shaping distributions and demographic processes across population ranges.

Experiences of occupational therapy students undertaking an Aboriginal and Torres Strait Islander health module: embedding cultural responsiveness in professional curricula.

Objective Along with other Australian health professionals, occupational therapy students need to understand Aboriginal and Torres Strait Islander culture and health issues to develop their capacity to work effectively with this community and meet accreditation standards. The study aimed to explore the learning experiences of occupational therapy students during a module focused on Aboriginal and Torres Strait Islander peoples' health issues and approaches. Methods A qualitative descriptive method was used.

Utilising the CREATE quality appraisal tool to analyse Aboriginal and Torres Strait Islander peoples' involvement and reporting of cancer research in Australia.

Objective: We aimed to evaluate Aboriginal and Torres Strait Islander involvement in research focusing on cancer experiences using an Aboriginal and Torres Strait Islander quality appraisal tool (the QAT).

Methods: We conducted a systematic review of the peer-reviewed literature on Aboriginal and Torres Strait Islander peoples' experiences associated with cancer, recently published elsewhere. We then appraised articles for the inclusion of Aboriginal and Torres Strait Islander-led research, community consultation, and involvement.

Pnictogen-Rich Heterocycles Derived from a Phosphadiazonium Cation.

Heterocycles that pair main group elements and nitrogen are extremely important within the π-conjugated heterocycles research community. Compared to the vast number of boron-nitrogen heterocycles, those that include phosphorus are less common. Furthermore, the use of phosphorus-nitrogen triple bonds of any type to prepare such compounds is unprecedented.

Systematic review of Aboriginal and Torres Strait Islander peoples' experiences and supportive care needs associated with cancer.

Background: Persistent disparities exist between Aboriginal and Torres Strait Islander peoples (the Indigenous peoples of Australia) and non-Indigenous Australians associated with cancer, with Aboriginal and Torres Strait Islander peoples experiencing a longer time to treatment, higher morbidity rates, and higher mortality rates. This systematic review aimed to investigate findings and recommendations in the literature about the experiences and supportive care needs of Aboriginal and Torres Strait Islander peoples with cancer in Australia.

Methods: A qualitative systematic review was conducted using thematic analysis.

The Australian Traumatic Brain Injury Initiative: Single Data Dictionary to Predict Outcome for People With Moderate-Severe Traumatic Brain Injury.

In this series of eight articles, the Australian Traumatic Brain Injury Initiative (AUS-TBI) consortium describes the Australian approach used to select the common data elements collected acutely that have been shown to predict outcome following moderate-severe traumatic brain injury (TBI) across the lifespan. This article presents the unified single data dictionary, together with additional measures chosen to facilitate comparative effectiveness research and data linkage. Consultations with the AUS-TBI Lived Experience Expert Group provided insights on the merits and considerations regarding data elements for some of the study areas, as well as more general principles to guide the collection of data and the selection of meaningful measures.

Burden of paediatric hospitalisations to the health care system, child and family: a systematic review of Australian studies (1990-2022).

Background: Paediatric hospitalisations represent a significant cost to the health system and cause significant burden to children and their families. Understanding trends in hospitalisation costs can assist with health planning and support strategies across stakeholders. The objective of this systematic review is to examine the trends in costs and burden of paediatric hospitalisations in Australia to help inform policy and promote the well-being of children and their families.

Temperature and microclimate refugia use influence migratory timings of a threatened grassland bird.

Background: Seasonal changes in resource availability are known to influence the migratory behaviour of animals, including both timing and distance. While the influence of environmental cues on migratory behaviour has been widely studied at the population level, it has rarely been examined at the spatial scale at which individuals experience their environment. Here, we test the hypothesis that individuals exposed to similar large-scale environmental cues may vary in migratory behaviour in response to the different microclimate conditions they experience at fine scales.

The overlooked importance of vagrancy in ecology and evolution.

Vagrancy is the occurrence of individuals outside the normal geographic range of their species. These rare and unpredictable events have long been neglected by the scientific community, belying a growing body of evidence that vagrancy can have an important role in eco-evolutionary processes at both population and community scales.

Preferences for telehealth: A qualitative study with people accessing a new mental health service.

Objectives: To examine preferences for telehealth versus in-person services for people who sought mental health support from an unfamiliar service during the COVID-19 pandemic and to identify the factors that influenced these preferences.

Methods: Data are drawn from semi-structured interviews with 45 participants (32 people who accessed mental health services, 7 informal support people, and 6 people who accessed services themselves as well as identifying as informal supports). Data relating to experiences of telehealth, comparisons with in-person services and preferences were coded inductively and analysed using qualitative content analysis.

Enhancing effective healthcare communication in Australia and Aotearoa New Zealand: Considerations for research, teaching, policy, and practice.

Objective: In this article we present a conceptual framework for enhancing effective healthcare communication in Australia and Aotearoa New Zealand.

Methods: Through an iterative, deliberative dialogue approach, we, as experts from a variety of health professions and academic disciplines, worked together to identify core values and considerations for healthcare communication across numerous health professions and disciplines and within research, teaching, policy, and practice contexts.

Results: The framework developed includes five core values at its centre: equitable, inclusive, evidence-based, collaborative, reflective.

Combining remote sensing and tracking data to quantify species' cumulative exposure to anthropogenic change.

Identifying when and where organisms are exposed to anthropogenic change is crucial for diagnosing the drivers of biodiversity declines and implementing effective conservation measures. Accurately measuring individual-scale exposure to anthropogenic impacts across the annual cycle as they move across continents requires an approach that is both spatially and temporally explicit-now achievable through recent parallel advances in remote-sensing and individual tracking technologies. We combined 10 years of tracking data for a long-distance migrant, (common cuckoo, Cuculus canorus), with multi-dimensional remote-sensed spatial datasets encompassing thirteen relevant anthropogenic impacts (including infrastructure, hunting, habitat change, and climate change), to quantify mean hourly and total accumulated exposure of tracked individuals to anthropogenic change across each stage of the annual cycle.

Multicomponent Synthesis of Poly(α-aminophosphine chalcogenide)s and Subsequent Depolymerization.

Multicomponent reactions of primary phosphines (R-PH), diimines (R'-N═C(H)-R-(H)C═N-R'), and chalcogens (O, S) generate poly(α-aminophosphine chalcogenide)s (-) through step-growth polymerization. Characterization of the linear polymers using P{H} diffusion-ordered NMR spectroscopy (DOSY) experiments aided in determining the molecular weight () of the material. Subjecting the polyphosphine oxide or sulfide to reducing conditions in the presence of a Lewis acid resulted in complete depolymerization of the polymers, quantitatively releasing the 1° phosphine and diimine () starting materials, with concomitant reduction of diimine to diamine ().

Disability workforce and the NDIS planning process in regional, rural and remote regions of Australia: Scoping review.

Background: The Australian geographically rural and remote disability workforce has historically demonstrated difficulties to keep up with the demand for quality services and supports for people with disability. In 2013, the National Disability Insurance Scheme (NDIS) was launched to provide individualised disability support packages to meet people's needs. To receive funding, people with disability are required to develop a NDIS plan.
