“Coming to a Strange Land”: The West African Migrant Women’s Establishment of Home and Family in a New Culture Within Australia

© 2015, © The Author(s) 2015. Purpose: Migrating and establishing a new life in another culture can have diverse health effects especially for women. This article explores the struggles and social adjustment issues that might constitute negatively to the health of West African migrant women living in Australia. Design: Qualitative storytelling. Audiotaped voluntary stories from 20 West African migrant women living in Sydney, Australia were transcribed and analyzed. Findings: Three themes are presented for discussion: (1) But it is different here: life in a new country; (2) I have to do it all by myself: communal versus individual living; and (3) They don’t listen to parents: perceived threats to the family unit. Conclusion/Implication for Practice: The demand for and the importance of nurses and midwives in supporting migrant families is demonstrated by findings suggesting that social adjustment into the Australian culture has a significant impact on both the nuclear and extended family unit of women

Influences of wind energy integration into the distribution network

Wind energy is one of the most promising renewable energy sources due to its availability and climate-friendly attributes. Large-scale integration of wind energy sources creates potential technical challenges due to the intermittent nature that needs to be investigated and mitigated as part of developing a sustainable power system for the future. Therefore, this study developed simulation models to investigate the potential challenges, in particular voltage fluctuations, zone substation, and distribution transformer loading, power flow characteristics, and harmonic emissions with the integration of wind energy into both the high voltage (HV) and low voltage (LV) distribution network (DN). From model analysis, it has been clearly indicated that influences of these problems increase with the increased integration of wind energy into both the high voltage and low voltage distribution network, however, the level of adverse impacts is higher in the LV DN compared to the HV DN

Design/Methodology: Through desktop analysis methodology, this paper will analyse six universities in Australia who are practicing different approaches in their undergraduate final year engineering project. This analysis will look in to the various types of final year projects undertaken, their learning outcomes, teaching methods and assessment measures. Findings: From these 6 case studies, this paper will provide a report on its implementation and assessment impact on final year projects based on the analysed results of qualitative review of course units in undergraduate programs. Conclusions: This paper shows the desktop analysis data and compared the six case studies of Australian universities. The above-summarized different final year engineering project approaches were extremely successful in identifying and promoting creativity and innovation through final year projects. From the comparison, it is clearly shown that Deakin University practices one of best assessment methods for the delivery of final year engineering project

Quality of life and visual function in Nigeria: findings from the National Survey of Blindness and Visual Impairment

Aims To assess associations of visual function (VF) and quality of life (QOL) by visual acuity (VA), causes of blindness and types of cataract procedures in Nigeria. Methods Multi-stage stratified cluster random sampling was used to identify a nationally representative sample of persons aged >= 40 years. VF/QOL questionnaires were administered to participants with VA = 6/12. Results VF/QOL questionnaires were administered to 2076 participants. Spearman's rank correlation showed a strong correlation between decreasing VA and VF/QOL scores (p< 0.0001) with greatest impact on social (p< 0.0001) and mobility-related activities (p< 0.0001). People who were blind due to glaucoma had lower VF and QOL scores than those who were blind due to cataract. Mean VF and QOL scores were lower after couching compared with conventional cataract surgery (mean VF score=51.0 vs 63.0 and mean QOL score=71.3 vs 79.3). Finally, VF and QOL scores were lower among populations with specific characteristics. Conclusions Populations with the following characteristics should be targeted to improve VF and QOL: people who are blind, older people, women, manual labourers, people living in rural areas, those living in the northern geopolitical zones, those practising Islamic and Traditionalism faith, those not currently married and those who have undergone couching

Market Opportunities and Profitability of Tree Crop Planting in Nigeria

Investing in trees offer financial and social returns for years to come and it is a lucrative long-term investment in Nigeria. Despite the substantial gain on investment in tree planting, only few people are still involved in the business. This paper analyzed the profitability of investment in tree crop planting for income generation. Benefit Cost Ratio (BCR) and Net Present Value (NPV) were calculated to determine the financial viability of tree crop planting. The study showed that tree crop planting is a profitable business as shown by positive NPV of ₦2,187,822.0 and N2, 782,214.97 for Tectonia grandis and Moringa oleifera plantations respectively, after 10-years of maturation and harvesting at 14 % discount rate with a B/C Ratio of 1.97 and 1.6 respectively. Also, NPV of N1, 575,487.10 for a 5-year small scale private nursery establishment with a B/C Ratio of 2.79 at a 14% discount rate also confirm that the investment on nursery establishment is highly profitable. It is recommended that with adequate support and incentives, farmers can take advantage of these opportunities and invest in nursery enterprise and tree crop sub-sector of the economy Keywords: Market opportunities, Tree planting, BCR, NP

Smart grid for a sustainable future

Advances in micro-electro-mechanical systems (MEMS) and information communication technology (ICT) have facilitated the development of integrated electrical power systems for the future. A recent major issue is the need for a healthy and sustainable power transmission and distribution system that is smart, reliable and climate-friendly. Therefore, at the start of the 21st Century, Government, utilities and research communities are working jointly to develop an intelligent grid system, which is now known as a smart grid. Smart grid will provide highly consistent and reliable services, efficient energy management practices, smart metering integration, automation and precision decision support systems and self healing facilities. Smart grid will also bring benefits of seamless integration of renewable energy sources to the power networks. This paper focuses on the benefits and probable deployment issues of smart grid technology for a sustainable future both nationally and internationally. This paper also investigates the ongoing major research programs in Europe, America and Australia for smart grid and the associated enabling technologies. Finally, this study explores the prospects and characteristics of renewable energy sources with possible deployment integration issues to develop a clean energy smart grid technology for an intelligent power system

Timing of antiretroviral therapy and TB treatment outcomes in patients with TB-HIV in Myanmar.

SETTING: Integrated HIV Care programme, Mandalay, Myanmar. OBJECTIVES: To determine time to starting antiretroviral treatment (ART) in relation to anti-tuberculosis treatment (ATT) and its association with TB treatment outcomes in patients co-infected with tuberculosis (TB) and the human immunodeficiency virus (HIV) enrolled from 2011 to 2014. DESIGN: Retrospective cohort study. RESULTS: Of 1708 TB-HIV patients, 1565 (92%) started ATT first and 143 (8%) started ART first. Treatment outcomes were missing for 226 patients and were thus not included. In those starting ATT first, the median time to starting ART was 8.6 weeks. ART was initiated after 8 weeks in 830 (53%) patients. Unsuccessful outcome was found in 7%, with anaemia being an independent predictor. In patients starting ART first, the median time to starting ATT was 21.6 weeks. ATT was initiated within 3 months in 56 (39%) patients. Unsuccessful outcome was found in 12%, and in 20% of those starting ATT within 3 months. Patients with CD4 count <100/mm(3) had a four times higher risk of an unsuccessful outcome. CONCLUSIONS: Timing of ART in relation to ATT was not an independent risk factor for unsuccessful outcome. Extensive screening for TB with rapid and sensitive diagnostic tests in HIV-infected persons and close monitoring of anaemia and immunosuppression are recommended to further improve TB treatment outcomes among patients with TB-HIV

Integration of renewable energy resources into the distribution network : a review on required power quality

Power quality is the critical element of modern power system network where more and more distributed energy resources (DER) can be found. Distributed generation, generates electricity from many small DER particularly from renewable sources. Distributed generator (DG) within the network from renewable energy resources (RER) like solar and wind, bring significant challenges to maintain acceptable power quality (PQ) at the consumer end. This paper investigates PQ issues associated with RER. It reviews existing PQ standards for distribution network (DN) and also summarized the experiences of several Distributed Network Service Provider (DNSP) while integrating DGs into the grid. It was found that few PQ parameter ranges varies in different standards due to lack of harmonization and that may hinder to accept bulk renewable energy into the grid
