Isolation and development of oil producing microorganisms including Thraustochytrids from Indian and Australian marine biodiversity

 The author isolated and characterized several Thraustochytrid strains from Indian and Australian marine biodiversity and compared these strains for their application in biodiesel and DHA production depend on their fatty acid profile. Strain having best productivity was further optimized for the coproduction of DHA and biodiesel.

Use of anthropogenic sea floor structures by Australian fur seals: potential positive ecological impacts of marine industrial development?

Human-induced changes to habitats can have deleterious effects on many species that occupy them. However, some species can adapt and even benefit from such modifications. Artificial reefs have long been used to provide habitat for invertebrate communities and promote local fish populations. With the increasing demand for energy resources within ocean systems, there has been an expansion of infrastructure in near-shore benthic environments which function as de facto artificial reefs. Little is known of their use by marine mammals. In this study, the influence of anthropogenic sea floor structures (pipelines, cable routes, wells and shipwrecks) on the foraging locations of 36 adult female Australian fur seals (Arctocephalus pusillus doriferus) was investigated. For 9 (25%) of the individuals, distance to anthropogenic sea floor structures was the most important factor in determining the location of intensive foraging activity. Whereas the influence of anthropogenic sea floor structures on foraging locations was not related to age and mass, it was positively related to flipper length/standard length (a factor which can affect manoeuvrability). A total of 26 (72%) individuals tracked with GPS were recorded spending time in the vicinity of structures (from <1% to >75% of the foraging trip duration) with pipelines and cable routes being the most frequented. No relationships were found between the amount of time spent frequenting anthropogenic structures and individual characteristics. More than a third (35%) of animals foraging near anthropogenic sea floor structures visited more than one type of structure. These results further highlight potentially beneficial ecological outcomes of marine industrial development.

Social development measures associated with problem behaviours and weight status in Australian adolescents

During the adolescent years, substance use, anti-social behaviours and overweight/obesity are amongst the major public health concerns. We investigate if risk and protective factors associated with adolescent problem behaviours and substance use are also associated with weight status in young Australian adolescents. Data comes from the 2006 Healthy Neighbourhoods study, a cross-sectional survey of students attending primary (grade 6, mean age 11) and secondary (grade 8, mean age 12) schools in 30 communities across Australia. Adolescents were classified as not overweight, overweight or obese according to international definitions. Logistic and linear regression analyses, adjusted for age, gender and socio-economic disadvantage quartile, were used to quantify associations between weight status (or BMI z-score) and the cumulative number of problem behaviour risk and protective factors. Prevalence of overweight and obesity was 22.6 % (95 % confidence interval (CI), 21.2–24.0 %) and 7.2 % (CI, 6.3–8.3 %). Average number of risk and protective factors present was 4.0 (CI, 3.7–4.2) and 6.2 (CI, 6.1–6.3). Independently, total number of risk factors present was positively associated with likelihood of overweight and obesity, while number of protective factors present was inversely associated with the likelihood of being above a healthy weight. When both risk and protective factors were included in a regression model, only risk factors were associated with the likelihood of being overweight or obese. Average BMI z-score increased by 0.03 units with each additional risk factor present. Prevention programmes targeting developmental risk and protective factors in adolescents that reduce substance use and problem behaviours may also benefit physical health.

Sticking up for Victoria? - Victoria's Legislative Council inquires into the performance of the Australian Health Practitioner Regulation Agency

This article analyses the report of the Victorian Legislative Council’s Legal and Social Issues Legislation Committee (‘Committee’) from its Inquiry into the Performance of the Australian Health Practitioner Regulation Agency (AHPRA). AHPRA is a national body that provides administrative support for the National Registration and Accreditation Scheme (NRAS), under which practitioners in 14 health professions across Australia are regulated. The article considers the Committee’s fi ndings and recommendations in light of the impetuses for the creation of the NRAS, as well as the structure and implementation of the NRAS and AHPRA. It is argued that that the value of the Committee’s report is confi ned to its identifi cation of important issues concerning the NRAS and AHPRA that, in the near future, will require a more critical and comprehensive investigation than the Committee undertook.

Establishing insurance markets in settler economies. a comparison of Australian and South Africa insurance markets, 1820-1910

How did insurance markets in the settler economies of Australia and South Africa develop? This paper investigates the establishment of the local insurance industries in two settler economies in the wake of the absence of comparative studies in the emergence of insurance markets in the periphery. The paper compares conditions in these settler economies and notes the innovative role of local entrepreneurs. British insurance companies extended operations into the British colonies, but local interests emerged to challenge their dominance. Innovations in organisational form, product offerings and distribution channels afforded local entrepreneurs a competitive advantage in the life market. Collusion in the fire market restricted innovative practices and retained foreign control. This article explains the agency of local entrepreneurs in the emergence of insurance markets in two settler societies at the end of the nineteenth century. This historical development path has notable implications for the current development of insurance markets in Africa.

Holocene record of Tuggerah Lake estuary development on the Australian east coast: sedimentary responses to sea-level fluctuations and climate variability

We investigated the Holocene palaeo-environmental record of the Tuggerah Lake barrier estuary on the south-east coast of Australia to determine the influence of local, regional and global environmental changes on estuary development. Using multi-proxy approaches, we identified significant down-core variation in sediment cores relating to sea-level rise and regional climate change. Following erosion of the antecedent land surface during the post-glacial marine transgression, sediment began to accumulate at the more seaward location at ~8500. years before present, some 1500. years prior to barrier emplacement and ~4000. years earlier than at the landward site. The delay in sediment accumulation at the landward site was a consequence of exposure to wave action prior to barrier emplacement, and due to high river flows of the mid-Holocene post-barrier emplacement. As a consequence of the mid-Holocene reduction in river flows, coupled with a moderate decline in sea-level, the lake experienced major changes in conditions at ~4000. years before present. The entrance channel connecting the lake with the ocean became periodically constricted, producing cyclic alternation between intervals of fluvial- and marine-dominated conditions. Overall, this study provides a detailed, multi-proxy investigation of the physical evolution of Tuggerah Lake with causative environmental processes that have influenced development of the estuary.

Development, implementation and evaluation of a clinical research engagement and leadership capacity building program in a large Australian health care service

BACKGROUND: Health professionals need to be integrated more effectively in clinical research to ensure that research addresses clinical needs and provides practical solutions at the coal face of care. In light of limited evidence on how best to achieve this, evaluation of strategies to introduce, adapt and sustain evidence-based practices across different populations and settings is required. This project aims to address this gap through the co-design, development, implementation, evaluation, refinement and ultimately scale-up of a clinical research engagement and leadership capacity building program in a clinical setting with little to no co-ordinated approach to clinical research engagement and education.

METHODS/DESIGN: The protocol is based on principles of research capacity building and on a six-step framework, which have previously led to successful implementation and long-term sustainability. A mixed methods study design will be used. Methods will include: (1) a review of the literature about strategies that engage health professionals in research through capacity building and/or education in research methods; (2) a review of existing local research education and support elements; (3) a needs assessment in the local clinical setting, including an online cross-sectional survey and semi-structured interviews; (4) co-design and development of an educational and support program; (5) implementation of the program in the clinical environment; and (6) pre- and post-implementation evaluation and ultimately program scale-up. The evaluation focuses on research activity and knowledge, attitudes and preferences about clinical research, evidence-based practice and leadership and post implementation, about their satisfaction with the program. The investigators will evaluate the feasibility and effect of the program according to capacity building measures and will revise where appropriate prior to scale-up.

DISCUSSION: It is anticipated that this clinical research engagement and leadership capacity building program will enable and enhance clinically relevant research to be led and conducted by health professionals in the health setting. This approach will also encourage identification of areas of clinical uncertainty and need that can be addressed through clinical research within the health setting.

Australian real estate management and development companies and women directors

Purpose – There is a large literature advocating the importance of a greater proportion of women directors on boards of publicly listed firms. The purpose of this paper is to examine the numbers and proportions of women directors, including women executive directors, on listed Australian Real Estate Management and Development (REMD) companies to identify how prevalent women directors are on such boards.
Design/methodology/approach – The study examines the numbers and proportions of women directors for 35 REMDs in 2011 and compares this to the broad board composition data on 1,715 Australian Stock Exchange listed entities. Statistically significant findings are evident due to the identified low proportions.
Findings – The study finds that of all the Financials Sub Industry sector groups, REMDs have the lowest proportion of female directors on theirs boards – eight women on each of 35 company boards compared to 159 men on these 35 boards at 2011. Of the eight, there were only two women executive directors on boards compared to 50 men. Statistically, it appears that having women directors on REMD boards is not considered important. Even at December 2014, there are only ten women on seven company boards and only one remaining executive director of an REMD company.
Practical implications – Given that female board representation is positively related to accounting returns and that there is a growing voice for legislation to impose mandatory proportions of women directors on boards around the world, it may be in the interests of REMD boards to consider appointing more women more quickly.
Originality/value – The study is the first to examine the numbers and proportions of women directors amongst REMD companies to identify the paucity of such women directors.

A survey of Australian human services agency software usage

Human Services agencies use a wide range of software systems to manage caseloads, maintain records, deliver services to clients, and for interagency communication. Some systems are generic, such as Word or Excel, while some are specialized to the organization, such as specialized databases for tracking case notes. Some software systems are shared across organizations. We surveyed nearly 40 Australian Human Services agencies to ascertain the range of software currently in use by agencies and their opinions on it, with a view to identifying promising new Human Services applications. We interviewed representatives from a selection of smaller agencies. This resulted in detailed feedback on key issues to consider when developing and deploying new Human Services software.

Inclusive pedagogy in Australian universities: a review of current policies and professional development activities

This article reports on activities undertaken by Australian universities to support academic staff to provide inclusive teaching. The findings of two lines of inquiry are reported - a desktop audit of the presence of inclusive teaching or universal design for learning (UDL) in publically available policies and procedures documents, and a survey of the methods adopted to build staff capacity to provide inclusive teaching and learning. Just over a third (34.21%) of Australian universities referred to inclusive teaching or UDL in their policies and procedures. A wide range of current practices in professional development for inclusive teaching was reported, with the most frequent being one-off workshops focussing on accommodating specific groups of students. Improved institutional support through policies, procedures and professional development would enable Australian higher education teachers to provide quality inclusive teaching to all students.

EAL teacher-agency: implications for participation in professional development

Teachers construct their practice, education and professionaldevelopment within two domains of professionalism: sponsored andindependent. The association between these two domains, however,is complex; it is overlapping, inseparable and sometimes uneasy. Thecomplexity is further exacerbated by the codependent nature ofassociation between the teacher and employment context in whichteachers’ and institutions’ trajectories for professional developmentmay vary. This situation calls into question the discrete treatmentgiven to and received by sponsored and independent professionalismin conceptualisations of teacher professional development. We arguethat, in both domains, teachers’ agency as learners is crucial for theirprofessional development and institutional efficacies. We critique theostensible disconnect and tensions that exist between the domains ofsponsored and independent professionalism in relation to teachingEnglish as an additional language and discuss how principles ofsponsored and independent professional development initiativescan be harnessed for optimal teacher learning.discuss how principles ofsponsored and independent professional development initiativescan be harnessed for optimal teacher learning.

Savings provisions in Australian electoral law : their forms, functions and historical development

The introduction of universal suffrage in 1902 established voting as a right for adult Australians who were British subjects and over 21 years of age. However, parties, parliaments, and electoral authorities have not been content with merely ensuring that citizens are entitled to vote. They have also enacted measures that aim to maximise citizen participation in elections. Turnout was made compulsory in 1925, which largely solved the ‘problem’ of voluntary abstention from the ballot box. A second concern has been disenfranchisement caused by incorrectly completed ballot papers. This situation arises when a voter submits a ballot that fails to comply with the legal requirements for a formal vote. Since the introduction of compulsory voting, debates about how to improve electoral turnout have largely concentrated on how to reduce rates of informality.The ‘problem’ of informality has long occupied the attention of electoral authorities and policy makers. This is due, in part, to the fact that rates of informality in Australia have been consistently high relative to other mature democracies. Moreover, the prevailing view in much of the Australian literature is that most informal voting is the result of mistakes and therefore ‘accidental’ or ‘unintentional’. Estimates of unintentional informal voting at national elections vary, but usually fall within the range of 80 to 85 per cent of informal votes cast. Even by the more conservative estimates of the Australian Electoral Commission (‘AEC’) the average rate of unintentional voting in the four national elections conducted in the period between 2001 and 2010 was 60.45 per cent.

Investigating ‘moments’ for student agency through a differentiated music curriculum

Research provides compelling evidence linking music-making to academic achievement and increased wellbeing for disengaged students. However, in the Australian context, education policy has narrowed its focus to literacy and numeracy, with an associated ‘accountability’ framework of mandated assessment and reporting practices. Within this context teachers are being asked to demonstrate how, through their pedagogical practices, they meet the needs of all their students. As a result of this, differentiation has become the lens through which student learning and engagement are being monitored. Drawing on data from a large state secondary school, this paper examines how a differentiated music curriculum is being implemented to support student agency. We demonstrate that, through a range of formal and informal music programs, agency is enhanced through the development of self-reflexive and self-referential learning practices. However, we suggest that differentiation, alone, does not unmask the reasons behind students’ different learning experiences nor does it necessarily redress entrenched educational inequalities. We also suggest that the ‘moments’ for student agency, created by these music programs, may have as much to do with the ‘fragile’ position of music within the broader school curriculum where the spotlight of high-stakes testing is directed elsewhere.
