Nitrogen removal by phytoplankton uptake through a temperate non-turbid estuary
No full textThe impact of phytoplankton growth on the ambient levels of nitrate, ammonium and urea at three stations in the Southampton Water estuarine system was assessed over the productive spring–summer period in 2001 using 15N tracer techniques. The relative contribution of the different nitrogen sources to total nitrogen uptake was also addressed. In general, ammonium uptake contributed >60% to total nitrogen uptake, but on some dates nitrate and urea uptake were dominant. Nitrogen depletion rates show that phytoplankton activity can, respectively, remove nitrate, ammonium and urea from the euphotic water column at rates of up to 9, 28 and 51% h?1 of the ambient levels. Area-wide N-uptake estimations suggest that over time scales of hours to a few days, uptake by phytoplankton can potentially remove 100% of riverine nitrogen loads during the productive period. Mass balance calculations suggest that 13 and 36% of the nitrate and 80 and 68% of the ammonium annual inputs to the Test and Southampton Water (SW) estuaries are respectively removed. N-removal however, was less significant than N-export from the system. Estimates indicate that >100% and approximately 70% of nitrate and ammonium inputs are respectively exported from the Test and SW estuaries to the adjacent estuary and to the Solent. It appears that nitrification, ammonium regeneration and wastewater inputs can account for the extra nitrogen within the system
Aboriginal and Torres Strait Islander People and dementia: a review of the research
No full textThis report outlines the prevalence of dementia and modifiable risk factors in Aboriginal and Torres Strait Islander communities.
Executive summary
The high rate of dementia in Aboriginal and Torres Strait Islander communities requires urgent attention. Aboriginal and Torres Strait Islander people experience dementia at an earlier age then the general population and this, combined with the steadily growing number of older Aboriginal and Torres Strait Islander people, will result in the number of people effected by dementia growing significantly in the coming years.
Although higher rates of dementia have been reported in Aboriginal and Torres Strait Islander people, the disease is often overlooked by Aboriginal and Torres Strait Islander communities, health workers and service providers. Geographical constraints in the provision of services, a lack of education and awareness in communities and by health workers and the prevalence of other chronic diseases have all posed considerable barriers to the recognition of dementia as an emerging health issue.
This paper includes the following recommendations to ensure that Aboriginal and Torres Strait Islander people, family members and communities have access to awareness, information, and appropriate support services for people with dementia
Spatial variation in Aboriginal and Torres Strait Islander people's access to primary health care
No full textThe report shows that overall, Australian Government funded Indigenous-specific primary health-care services appear to be well positioned relative to the geographic distribution of Aboriginal and Torres Strait Islander people and to the distribution of other GP services. However, there are a number of areas where Aboriginal and Torres Strait Islander people have very limited access to both Indigenous-specific services and GP services in general
National Aboriginal and Torres Strait Islander health plan 2013-2023
No full textIn 2008 Australian Governments committed to work with Aboriginal and Torres Strait Islander people on an incredibly important task - to achieve equality in health status and life expectancy between Aboriginal and Torres Strait Islander people and non-Indigenous Australians by the year 2031. The commitment – in the form of the Close the Gap Statement of Intent – creates the platform for this National Aboriginal and Torres Strait Islander Health Plan, which has been developed in partnership with Aboriginal and Torres Strait Islander people and their representatives.
This Health Plan provides a long-term, evidence-based policy framework as part of the overarching Council of Australian Governments’ (COAG) approach to Closing the Gap in Indigenous disadvantage, which has been set out in the National Indigenous Reform Agreement (NIRA) signed in 2008. The NIRA has established a framework of national targets and policy building blocks. Two of the Closing the Gap targets, to halve the gap in child mortality by 2018 and close the life expectancy gap by 2031, go directly to health outcomes, while others address social determinants of health such as education and employment.
The Health Plan builds on the United Nations Declaration on the Rights of Indigenous Peoples. It adopts a strengths-based approach to ensure policies and programs improve health, social and emotional wellbeing, and resilience and promote positive health behaviours. It emphasises the centrality of culture in the health of Aboriginal and Torres Strait Islander people and the rights of individuals to a safe, healthy and empowered life. The Health Plan also builds on existing strategies and planning approaches to improving Aboriginal and Torres Strait Islander health,
Picoeukaryote distribution in relation to nitrate uptake in the oceanic nitracline
No full textWe investigated the relationship between picoeukaryote phytoplankton (<2 μm) and the deep layer of new production (NO3- uptake) in the nitracline of the eastern subtropical North Atlantic Ocean. Indices of NO3- uptake kinetics obtained within the lower 15% of the euphotic zone demonstrate that subsurface NO3- uptake maxima are coincident with localised peaks in maximum uptake rates (Vmax) and, crucially, with maximum picoeukaryote abundance. The mean rate of NO3- utilization at the nitracline is typically 10-fold higher than in surface waters despite much lower in-situ irradiances. These observations confirm a high affinity for NO3-, most likely by the resident picoeukaryote community, and we conservatively estimate mean cellular uptake rates of between 0.27 and 1.96 fmol NO3- cell-1 h-1. Greater scrutiny of the taxonomic composition of the picoeukaryote group is required to further understand this deep layer of new production and its importance for nitrogen cycling and export production given longstanding assumptions that picoplankton do not contribute directly to export fluxes
Aboriginal and Torres Strait Islander health performance framework 2012 report: Australian Capital Territory
No full textThis report provides the latest information on how Aboriginal and Torres Strait Islander people are faring according to a range of indicators on health status, determinants or health and health system performance.Executive summaryThe Aboriginal and Torres Strait Islander Health Performance Framework 2012 report for the Australian Capital Territory finds areas of improvement in the health of Aboriginal and Torres Strait Islander people living in the territory, including:a significant increase in health assessments for Aboriginal and Torres Strait Islander people aged 55 years and over recorded through Medicare since the introduction of the National Partnership Agreement on Closing the Gap in Indigenous Health Outcomes in July 2009corresponding increases in allied health-care services claimed by Aboriginal and Torres Strait Islander people through Medicare since 1 July 2009. Aboriginal and Torres Strait Islander people have higher rates of general practitioner management plans and team care arrangements than non-Indigenous Australiansimmunisation coverage rates for Aboriginal and Torres Strait Islander children are close to those for other Australian children by age 5some improvements in literacy for Aboriginal and Torres Strait Islander students in Year 3 and 5 between 2009 and 2011apparent retention rates from Year 7 to Year 10 and from Year 11 to Year 12 are higher for Aboriginal and Torres Strait Islander people in the Australian Capital Territory than for Aboriginal and Torres Strait Islander people nationally.Areas of concern include:high rates of smoking during pregnancy (51% total)around half of Aboriginal and Torres Strait Islander people aged 18 and over reported drinking alcohol at short-term risky/high-risk levels in the past 12 months, which was higher than the proportion for non-Indigenous people and for Indigenous people nationallyalmost two-thirds (63%) of Aboriginal and Torres Strait Islander people aged 18 and over in the Australian Capital Territory have a disability or long-term health condition, which is higher than the proportion for Aboriginal and Torres Strait Islander people nationally (41%)breast cancer screening rates for Aboriginal and Torres Strait Islander women are lower than for other women
Review of higher education access and outcomes for Aboriginal and Torres Strait Islander people: final report
No full textThis report proposes a collaborative approach be developed involving universities, governments, professional bodies, the business sector and communities working together to improve the lives of Aboriginal and Torres Strait Islander people through higher education.
The Review of Higher Education Access and Outcomes for Aboriginal and Torres Strait Islander People follows on from the 2008 Review of Higher Education (the Bradley Review) by proposing measures that address what is a significant gap between Aboriginal and Torres Strait Islander and non-Indigenous Australians’ higher education outcomes.
The Bradley Review recognised, in light of Australia’s growing economic and social policy challenges, the need for specific strategies to increase the participation in higher education of groups currently underrepresented within the system, particularly those from a low socio-economic status (SES) background. The Bradley Review specifically identified the need to address access and outcomes in higher education for Aboriginal and Torres Strait Islander people.
The terms of reference for the Review of Higher Education Access and Outcomes for Aboriginal and Torres Strait Islander People (the Review) asked the Review Panel (the Panel) to provide advice and make recommendations in relation to:
achieving parity for Aboriginal and Torres Strait Islander students, researchers, and academic and non-academic staff
best practice and opportunities for change inside universities and other higher education providers (spanning both Indigenous-specific units and whole-of-university culture, policies, activities and programs)
the effectiveness of existing Commonwealth Government programs that aim to encourage better outcomes for Aboriginal and Torres Strait Islander Australians in higher education
the recognition and equivalence of Indigenous knowledge in the higher education sector.
The Panel proposes a collaborative approach be developed involving universities, governments, professional bodies, the business sector and communities working together to improve the lives of Aboriginal and Torres Strait Islander people through higher education. Strategies outlined in the report include attracting and retaining more Aboriginal and Torres Strait Islander students and staff, improving academic achievement, simplifying and better focusing university and government support programs and ensuring that graduates are better equipped to meet the needs of Aboriginal and Torres Strait Islander people through embedding Indigenous perspectives in teaching, learning and research.
The expert panel consisted of Professor Larissa Behrendt (Chair), Professor Steven Larkin, Mr Robert Griew and Ms Patricia Kelly
Situació de Màrius Torres en el context de la poesia europea de la primera meitat del segle xx
No full textThis article analyzes focuses on Màrius Torres’ situation in the context of European poetry in the first third of the twentieth century: as a reader and author, as a translator and with attention to his interest in great poetical trends of the time. The analysis is based on three elements: Màrius Torres’ poetry translations; his affinities with some significant European poets, and the commentary of some representative poems: «La màscara», «En el silenci obscur d'unes parpelles closes...», «Abendlied,» which illustrate the situation of his poetry in an European context
El keynesianismo desde la óptica de los países atrasados: su adaptación por Manuel de Torres a la Economía española
No full textEditada en la Fundación SEPIEl siguiente trabajo se propone estudiar la introducción del keynesianismo
en España a través de los escritos de Manuel de Torres, probablemente el
más activo de los economistas que adoptaron de una u otra forma la nueva
doctrina en la posguerra. Dada la escasez en España de una reflexión teórica
original, el artículo prestará especial atención a la adaptación que realiza Torres
de las ideas keynesianas al contexto de la economía española. En particular,
las ideas keynesianas contribuyeron decisivamente a sustituir la vía agraria
defendida por Torres como camino de desarrollo de la economía española
por el industrialismo que sostiene en la posguerra. El articulo ofrece las claves
de esta evolución doctrinal y reivindica el papel de las ideas económicas como
poderoso instrumento de transformación.The main aim of the article is to analyse the introduction of keynesianism
into Spain through the Manuel de Torres' works, the most active proponent
of the new doctrine duríng the forties and fifties. The article focus on the
adaptation to the Spanish context of the Keynes's ideas by Manuel de Torres.
In particular, Keynesianism contrihuted to replace the agrarian ideas defended
by Torres in the thirties by a new interest in industrial development during
the 40's and 50's. Thus, the article provides an explanation of Torres' doctrinal
evolution and vindicates the role played by the economic ideas as an instrument
of transformation. These ideas contributed to change the Torres perception
of the Spanish economic reality.Publicad
Enhancing the implementation of the Aboriginal and Torres Strait Islander Child Placement Principle: policy and practice considerations
No full textOverview
The Aboriginal and Torres Strait Islander Child Placement Principle ("the Principle") was developed in recognition of the devastating effects of forced separation of Indigenous children from families, communities and culture. The Principle exists in legislation and policy in all Australian jurisdictions, and while its importance is recognised in many boards of inquiry and reviews into child protection and justice systems, there are significant concerns about the implementation of the Principle. Recent estimates suggest the Principle has been fully applied in as few as 13% of child protection cases involving Aboriginal and Torres Strait Islander children. The purpose of this paper is to explore the contemporary understanding of the Principle, and review the multiple and complex barriers at the policy and practice levels which are impeding its implementation. Promising approaches that might address these barriers are also examined.
Key messages
The Aboriginal and Torres Strait Islander Child Placement Principle was developed in response to the trauma experienced by individuals, families and communities from government policies that involved the widespread removal of Aboriginal and Torres Strait Islander children.
The fundamental goal of the Principle is to enhance and preserve Aboriginal and Torres Strait Islander children’s connection to family and community, and sense of identity and culture.
The Principle is often conceptualised as the “placement hierarchy”, in which placement choices for Aboriginal and Torres Strait Islander children start with family and kin networks, then Indigenous non-related carers in the child’s community, then carers in another Aboriginal or Torres Strait Islander community. If no other suitable placement with Aboriginal and/or Torres Strait Islander carers can be sought, children are placed with non-Indigenous carers as a last resort, provided they are able to maintain the child’s connections to their family, community and cultural identity
