Problematic placement : pathways pre-service teachers’ perspectives on their infant/toddler placement

The inclusion of an infant/toddler placement in a ‘pathways’ early childhood teaching degree, where students already have qualifications and experience in working with young children, can be problematic. This pilot study investigated student teachers’ views on their infant/toddler (birth-to-two-years) placement. Sixty-six students completing their early childhood education degree at an Australian university responded to a survey seeking their perspectives on the effectiveness of the placement in developing teacher confidence, knowledge and skills, and the quality of the supervision they received. The participants had entered their degree with a two-year Diploma of Children’s Services. Responses indicated significant dissatisfaction with the quality of supervision, the absence of teacher-mentors, and the lack of opportunities to practise new approaches. Participants commented that they ‘already knew’ how to work with this age group, and that they aspired to work with older children. The results align with other findings on factors associated with positive placements, and raise questions about the effectiveness of the infant/toddler placement in its current form.

Global, regional, and national incidence and mortality for HIV, tuberculosis, and malaria during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013

BACKGROUND: The Millennium Declaration in 2000 brought special global attention to HIV, tuberculosis, and malaria through the formulation of Millennium Development Goal (MDG) 6. The Global Burden of Disease 2013 study provides a consistent and comprehensive approach to disease estimation for between 1990 and 2013, and an opportunity to assess whether accelerated progress has occured since the Millennium Declaration. METHODS: To estimate incidence and mortality for HIV, we used the UNAIDS Spectrum model appropriately modified based on a systematic review of available studies of mortality with and without antiretroviral therapy (ART). For concentrated epidemics, we calibrated Spectrum models to fit vital registration data corrected for misclassification of HIV deaths. In generalised epidemics, we minimised a loss function to select epidemic curves most consistent with prevalence data and demographic data for all-cause mortality. We analysed counterfactual scenarios for HIV to assess years of life saved through prevention of mother-to-child transmission (PMTCT) and ART. For tuberculosis, we analysed vital registration and verbal autopsy data to estimate mortality using cause of death ensemble modelling. We analysed data for corrected case-notifications, expert opinions on the case-detection rate, prevalence surveys, and estimated cause-specific mortality using Bayesian meta-regression to generate consistent trends in all parameters. We analysed malaria mortality and incidence using an updated cause of death database, a systematic analysis of verbal autopsy validation studies for malaria, and recent studies (2010-13) of incidence, drug resistance, and coverage of insecticide-treated bednets. FINDINGS: Globally in 2013, there were 1·8 million new HIV infections (95% uncertainty interval 1·7 million to 2·1 million), 29·2 million prevalent HIV cases (28·1 to 31·7), and 1·3 million HIV deaths (1·3 to 1·5). At the peak of the epidemic in 2005, HIV caused 1·7 million deaths (1·6 million to 1·9 million). Concentrated epidemics in Latin America and eastern Europe are substantially smaller than previously estimated. Through interventions including PMTCT and ART, 19·1 million life-years (16·6 million to 21·5 million) have been saved, 70·3% (65·4 to 76·1) in developing countries. From 2000 to 2011, the ratio of development assistance for health for HIV to years of life saved through intervention was US$4498 in developing countries. Including in HIV-positive individuals, all-form tuberculosis incidence was 7·5 million (7·4 million to 7·7 million), prevalence was 11·9 million (11·6 million to 12·2 million), and number of deaths was 1·4 million (1·3 million to 1·5 million) in 2013. In the same year and in only individuals who were HIV-negative, all-form tuberculosis incidence was 7·1 million (6·9 million to 7·3 million), prevalence was 11·2 million (10·8 million to 11·6 million), and number of deaths was 1·3 million (1·2 million to 1·4 million). Annualised rates of change (ARC) for incidence, prevalence, and death became negative after 2000. Tuberculosis in HIV-negative individuals disproportionately occurs in men and boys (versus women and girls); 64·0% of cases (63·6 to 64·3) and 64·7% of deaths (60·8 to 70·3). Globally, malaria cases and deaths grew rapidly from 1990 reaching a peak of 232 million cases (143 million to 387 million) in 2003 and 1·2 million deaths (1·1 million to 1·4 million) in 2004. Since 2004, child deaths from malaria in sub-Saharan Africa have decreased by 31·5% (15·7 to 44·1). Outside of Africa, malaria mortality has been steadily decreasing since 1990. INTERPRETATION: Our estimates of the number of people living with HIV are 18·7% smaller than UNAIDS's estimates in 2012. The number of people living with malaria is larger than estimated by WHO. The number of people living with HIV, tuberculosis, or malaria have all decreased since 2000. At the global level, upward trends for malaria and HIV deaths have been reversed and declines in tuberculosis deaths have accelerated. 101 countries (74 of which are developing) still have increasing HIV incidence. Substantial progress since the Millennium Declaration is an encouraging sign of the effect of global action. FUNDING: Bill & Melinda Gates Foundation.

Global, regional, and national levels and causes of maternal mortality during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013

BACKGROUND: The fifth Millennium Development Goal (MDG 5) established the goal of a 75% reduction in the maternal mortality ratio (MMR; number of maternal deaths per 100,000 livebirths) between 1990 and 2015. We aimed to measure levels and track trends in maternal mortality, the key causes contributing to maternal death, and timing of maternal death with respect to delivery. METHODS: We used robust statistical methods including the Cause of Death Ensemble model (CODEm) to analyse a database of data for 7065 site-years and estimate the number of maternal deaths from all causes in 188 countries between 1990 and 2013. We estimated the number of pregnancy-related deaths caused by HIV on the basis of a systematic review of the relative risk of dying during pregnancy for HIV-positive women compared with HIV-negative women. We also estimated the fraction of these deaths aggravated by pregnancy on the basis of a systematic review. To estimate the numbers of maternal deaths due to nine different causes, we identified 61 sources from a systematic review and 943 site-years of vital registration data. We also did a systematic review of reports about the timing of maternal death, identifying 142 sources to use in our analysis. We developed estimates for each country for 1990-2013 using Bayesian meta-regression. We estimated 95% uncertainty intervals (UIs) for all values. FINDINGS: 292,982 (95% UI 261,017-327,792) maternal deaths occurred in 2013, compared with 376,034 (343,483-407,574) in 1990. The global annual rate of change in the MMR was -0·3% (-1·1 to 0·6) from 1990 to 2003, and -2·7% (-3·9 to -1·5) from 2003 to 2013, with evidence of continued acceleration. MMRs reduced consistently in south, east, and southeast Asia between 1990 and 2013, but maternal deaths increased in much of sub-Saharan Africa during the 1990s. 2070 (1290-2866) maternal deaths were related to HIV in 2013, 0·4% (0·2-0·6) of the global total. MMR was highest in the oldest age groups in both 1990 and 2013. In 2013, most deaths occurred intrapartum or postpartum. Causes varied by region and between 1990 and 2013. We recorded substantial variation in the MMR by country in 2013, from 956·8 (685·1-1262·8) in South Sudan to 2·4 (1·6-3·6) in Iceland. INTERPRETATION: Global rates of change suggest that only 16 countries will achieve the MDG 5 target by 2015. Accelerated reductions since the Millennium Declaration in 2000 coincide with increased development assistance for maternal, newborn, and child health. Setting of targets and associated interventions for after 2015 will need careful consideration of regions that are making slow progress, such as west and central Africa.

Modelling of vocational excellence: An international perspective

This paper provides an overview of the findings from a Finnish Ministry of Education sponsored project called ‘Modeling of Vocational Excellence’ (MoVE) and an Australian application and adaptation of this research: ‘MoVE Australia’. The Finnish MoVE research project was conducted by the Research Centre for Vocational Education at the University of Tampere explored WorldSkills as a site for the development of expertise and pursuit of excellence. It addressed questions about the abilities and attributes of competitors, and the social and environmental factors which influenced their skill development. The Australian project administered the Finnish MoVE survey to the Australian international WorldSkills team which will compete in London in October 2011 and introduced a second survey about competitor experience, designed to give voice to the young people involved in WorldSkills. This survey was administered to competitors, trainers and judges participating in the WSA National Competition held in Brisbane in May 2010, and later to employers and families. The Australian extension of the Finnish research has generated a rich source of experiential data, providing fresh insights into career choice and training. The findings of the research offer opportunities for reviewing elements of trade training and raise questions about the role of a competitive community of practice in quality skill formation and about the current level of research on this aspect of Australia VET practice.

Challenges to providing work integrated learning to international business students at Australian universities

Purpose – The purpose of this paper is to report on a three-year Australian study of international business and accounting students and the transition to employment. For international students seeking to differentiate themselves in a highly competitive global labour market, foreign work experience is now an integral part of the overseas study “package”. Work-integrated learning (WIL) is seen to provide critical “employability” knowledge and skills, however, international students have low participation rates. The high value placed on WIL among international students poses challenges for Australia as well as opportunities. Understanding the issues surrounding international students and WIL is closely linked to Australia’s continued success in the international education sector which has broad, long-term, social and economic implications.Design/methodology/approach – This paper draws on 59 interviews with a range of stakeholders including international students, universities, government, employers and professional bodies. Central to the paper is an in-depth case study of WIL in the business and accounting discipline at one Australian university.Findings – Providing international students with access to discipline-related work experience has emerged as a critical issue for Australian universities. The study finds that enhancing the employability skills of internationals students via integrated career education, a focus on English language proficiency and “soft skills” development are central to success in WIL. Meeting the growing demand for WIL among international students requires a multipronged approach which hinges on cooperation between international students, universities, employers and government.Originality/value – This project aims to fill a critical knowledge gap by advancing theories in relation to international students and WIL. While there is a significant body of research in the fields of international education and WIL, there is an absence of research exploring the intersection between the two fields. The study will contribute to the advancement of knowledge in both fields by exploring the emerging issue of WIL and international students.

International education, the formation of capital and graduate employment : Chinese accounting graduates’ experiences of the Australian labour market

Since the late 1970s, international education has steadily gained in popularity in China.An emerging middle class seeks to strengthen its position in China’s rapidly stratifyingsociety under its socialist market economy with the shift from wealth creation for all towealth concentration for a few. Previously, a foreign qualification was considered apassport to success in either the host or home country’s labour market. But the growingpopularity of overseas study, coupled with the massification of the Chinese highereducation, means Chinese international students are seeking to distinguish themselvesin an increasingly competitive global labour market. This longitudinal study of internationalgraduates, backgrounded by Australian employer perceptions, examines thejourneys of 13 Chinese accounting graduates as they attempt to transition from anAustralian university into the Australian labour market. Bourdieu’s thinking tools offield, capital, disposition and habitus are utilised to consider how different cultural,social and linguistic capitals inform employer understandings of ‘employability’ meantChinese accounting graduates significantly adjusted their life goals.

Photo induced silver on nano titanium dioxide as an enhanced antimicrobial agent for wool

In this study an effective nanocomposite antimicrobial agent for wool fabric was introduced. The silver loaded nano TiO(2) as a nanocomposite was prepared through UV irradiation in an ultrasonic bath. The nanocomposite was stabilized on the wool fabric surface by using citric acid as a friendly cross-linking agent. The treated wool fabrics indicated an antimicrobial activity against both Staphylococcus aureus and Escherichia coli bacteria. Increasing the concentration of Ag/TiO(2) nanocomposite led to an improvement in antibacterial activities of the treated fabrics. Also increasing the amount of citric acid improved the adsorption of Ag/TiO(2) on the wool fabric surface leading to enhance antibacterial activity. The EDS spectrum, SEM images, and XRD patterns was studied to confirm the presence of existence of nanocomposite on the fabric surface. The role of both cross-linking agent and nanocomposite concentrations on the results was investigated using response surface methodology (RSM).

Comparison of antimicrobial activity, phytochemical profile and minerals composition of garlic Allium sativum and Allium tuberosum

Allium species are considered to be one of the world's oldest cultivated vegetables. Most commonly used species of garlic in Pakistan and India is Allium sativum, while Allium tuberosum is mainly consumed and cultivated in China, Southeast Asia, and North-east part of India. The present study was conducted to compare the antimicrobial activity, nutritional value and antioxidant profile of Allium sativum and Allium tuberosum. The outcome indicates that Allium tuberosum have slightly higher antimicrobial activity, higher mineral profile, and enriched in antioxidants in comparison with Allium sativum. The highest antimicrobial activity of Allium tuberosum was noticed against Staphylococcus aureus and Bacillus subtilis with 43.9 and 40.7 mm zone of inhibition using 100% extract. Allium tuberosum contains high contents of calcium (28.662±.00mg/100 g), potassium (10.62±0.50) and zinc (59.00±1.00). Allium tuberosum also showed higher antioxidant activity (0.24±0.03 mg vitamin C equivalent (VCE)/g fresh weight in ferric reducing antioxidant power assay, 0.18±0.02 mg VCE/g fresh weight in 2,2-diphenyl-1-picrylhydrazyl assay and 1.09±0.12 mg VCE/g fresh weight in 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) assay) in comparison with Allium sativum.

In vitro comparative study of Bougainvillea spectabilis "stand" leaves and Bougainvillea variegata leaves in terms of phytochemicals and antimicrobial activity

Aim: To study the qualitative analysis of phytochemicals and antibacterial activity of the ethanolic and methanolic extracts of Bougainvillea spectabilis and Bougainvillea variegata leaves. Methods: Phytochemical constituents were determined qualitatively by the Harborne method, while antimicrobial activities were determined by measuring the zone of inhibition on Mueller Hinton Agar. Results: The maximum inhibitory effects were obtained against the Gram positive microbe Staphylococcus aureus for the methanolic extracts of both B. spectabilis [(28.54 ± 0.18) mm] and B. variegata [(21.97 ± 0.06) mm]. The Gram negative microbes Proteus vulgaris [(16.00 ± 0.15) mm] and Serratia marcescens [(16.00 ± 0.06) mm] gave maximum inhibitory effects for the ethanolic extracts of B. variegata, while Salmonella typhimurium [(17.26 ± 0.12) mm] gave a maximum zone of inhibition for the methanolic extract of B. spectabilis. No inhibitory effects were observed for the extracts of B. spectabilis or B. variegate against Enterococcus faecalis, Vibro cholera or Klebsiella pneumoniae. Conclusion: Both B. spectabilis and B. variegata possess significant antimicrobial activity that, following additional studies, could replace commercially known antibiotics. © 2012 China Pharmaceutical University.

Antimicrobial activity of Eucalyptus tereticornis and comparison with daily life antibiotics

Eucalyptus is a fast growing tree which has shown to possess high degree of resistance against stressed environmental conditions. Eucalyptus tereticornis is widely cultivated in various parts of the world even in Pakistan. The medicinal properties of this tree reside in its oil. The main aim of our study is to check the antimicrobial activity of this valuable tree and to compare it with commercially available antibiotics. Eucalyptus tereticornis oil was extracted from the fresh leaves and branch tips during flowering season from surrounding areas of Hazara University, Pakistan. Different concentrations of oil were checked against Gram positive bacteria Staphylococcus aureus (ATCC 6538), Enterococcus faecalis (ATCC 49452), Gram negative bacteria including Escherichia coli (ATCC 25922), Salmonella typhimurium (ATCC 14028) and Pseudomonas aeruginosa (ATCC 27853), and also against yeast Candiada albican (ATCC 2091). The oil was significantly active against all the microbes studied. The activity of E. tereticornis oil was compared with standard antibiotics Ciprofloxacin (CIP-5 μg), Chloramphenicol (C-30 μg), Tetracycline (TE-30 μg) and Ampicillin (AMP 25-μg). The comparison gives the significant results and proves the antimicrobial efficiency of this valuable plant.

Antibacterial activity of the venom of Heterometrus xanthopus

Heterometrus xanthopus (Scorpion) is one of the most venomous and ancient arthropods. Its venom contains anti-microbial peptides like hadrurin, scorpine, Pandinin 1, and Pandinin 2 that are able to effectively kill multidrug-resistant pathogens. The present study was conducted to evaluate the anti-bacterial activity of H. xanthopus venom. Six Gram-positive and Gram-negative bacterial strains were tested against 1/100, 1/10, and 1/1 fractions of distilled water diluted and crude venom. 1/100 and 1/10 dilutions were not successful in any of the six bacterial strains studied while the 1/1 dilution was effective on Bacillus subtilis ATCC 6633, Salmonella typhimurium ATCC 14028, and Pseudomonas aeruginosa ATCC 27853 with highest zone of inhibition were obtained on B. subtilis. Crude venom was effective against Enterococcus faecalis ATCC 14506, B. subtilis, S. typhimurium, and P. aeruginosa. The most effective results were observed on B. subtilis.

Gen green 4 Australia: a national study of demand for and supply of skills for sustainability

In this research, skills for sustainability are broadly conceived as including skills for social, economic and environmental sustainability – a triple bottom-line approach. Since 2009 Australian governments have been implementing an agreement that embeds skills for sustainability into vocational education and training, despite scant information about the actual levels of demand for, and supply of these skills. This study provides evidence on the actual depth and breadth of the take-up of these skills within Australian training organisations and workplaces. The demand studied in this research is that expressed by the primary consumers of Australian Vocational Education and Training (VET) services, students who engage in VET studies, this is known in the literature as social demand for education. VET students and teachers responded to two survey instruments that explored the sustainability values, behaviours, learning and teaching of Australian apprentices, trainees and their teachers. The results of this study show ‘a social demand’ for skills for sustainability. In summary, the results show that: •Apprentices, trainees and their teachers cared a great deal about social, economic and environmental sustainability; •Supply was closely aligned to social demand for skills for sustainability so that demand for skills for sustainability from VET students was almost entirely met; •There are important differences in the teaching, learning and utilisation of skills for sustainability that are related to gender and age; and •In-class learning of environmental skills has increased over time and now slightly outweighs learning of these skills at work, however community learning of these skills outweighs both. The findings suggest that: •Further action is required to embed green skills into the VET system, especially in the areas of energy efficiency and supply chains; •The VET system plays an important role in supporting community cohesion and economic literacy, especially for women; •It is important that social sustainability is properly considered in analysis informing VET policy; and •Gender differences in values and behaviours and gender and age differences in learning skills for sustainability have important implications for the design of future skills for sustainability programs. VET students and their teachers have unique insights into the supply of and demand for skills for sustainability, and this viewpoint can contribute, now and in the future, to the further development of skills for sustainability in Australia.
