How do Digital Immigrant Teachers (DITs) learn ICT for the information age?

This study reports about teacher learning and in particular, teachers who have extensive teaching experience but limited ICT knowledge and skills. The Digital Immigrant Teachers (DITs) grew up before digital technologies; they are not frequently confident or comfortable with ICT. Like all immigrants, they have to learn new and creative ways to enhance their survival in the third millennium, where the acceleration of knowledge has allowed communication and application of information to be rapidly disseminated. In order to fully participate in the technologically rich society DITs must actively engage in the construction of authentic and purposeful learning. This research came about as a result of the digital immigrants' struggles to construct and acquire the necessary knowledge and skills to teach in the Knowledge Economy and the Information Age. The experienced present day teachers, as digital immigrants are trying to teach digital natives (Prensky, 2001 & 2003). And in order to assist these teachers in their learning ICT struggle, it is imperative to understand the teacher learning process, and the learning style through which they acquire the knowledge and skills for this new milieu.

Health cosmopolitanism: melding universality and difference – the case of childbirth in post-conflict Timor Leste

ABSTRACTThis study will consider the case of TBAs (traditional birth attendants) under the health cosmopolitan banner. Fifteen interviews with health administrators, obstetricians, midwives, traditional birth attendants and women in Timor Leste, provide evidence : (1) that the WHO (1992) directive to dismiss the inclusion of TBAs within the formal maternity care system has been precipitous (2) that TBAs could, with adequate training in emergency obstetric techniques and hygienic practices, assist in meeting MDG No 5, and (3) that TBAs may assist in sustaining hybrid cosmologies and serving other cultural aims. Although Millennium Development Goals embrace the idea of the universal right to health, a human rights framework remains abstract and legalistic. I argue that health cosmopolitanism offers a more inclusive lens. Applied to maternity care it shifts childbirth to a central focus of government policy, obliges all nations to contribute international aid yet recognises the interpretation of complex needs at the local level. It defines a philosophy of care that is person-centred (not professional or institution-centred), ensures equal access to quality care (based not on ability to pay or other obstacles such as geographical distance) and choice of carer and modality (Western, traditional or hybrid). It underlines the argument here that TBAs trained in emergency obstetric care and hygiene and funded by international agencies would ensure every woman has a known carer, plus choice of location, modality and provider. Health cosmopolitanism thus embraces universality, individual autonomy, reciprocal respect and global responsibility.

Current state of China tourism research

Along with the tremendous growth of tourism development in China after its successful hosting of two international mega-events (i.e. the 2010 Shanghai World Expo and the 2010 Guangzhou Asian Games), a modest body of academic research on tourism in China has been developed since the start of the second decade of the new millennium. To supplement the continuous development of China's tourism industry, this study presents a review of 147 research articles from tourism journals during the period 2010-2012. Through content analysis, the empirical findings indicate that tourist behaviour and experience was the most researched theme, followed by culture and heritage studies. The trend of research collaboration, particularly international collaboration, was evident among the analysed studies. This study also presents the diversity in recent research in the realm of tourism in China in terms of research context, geographical coverage, data collection and analysis method, and institutional contribution.

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.

Pluralist risk cultures: the sociology of childbirth

Western medical approaches to childbirth typically locate risk in women’s bodies,making it axiomatic that ‘good’ maternity care is associated with medically trainedattendants. This logic has been extrapolated to developing societies, like Vanuatu, anIsland state in the Pacific, struggling to provide good maternity care in line with theWorld Health Organization’s Millennium Development Goals. These goals include thereduction of maternal mortality by two-thirds by 2015, but Vanuatu must overcomechallenging hurdles – medical, social and environmental – to achieve this goal.Vanuatu is a hybridised society: one where the pre-modern and modern coincide inparallel institutions, processes and practices. In 2010, I undertook an inductive study of30 respondents from four main subcultures – women living in outer rural communitieswith limited access to Western-trained health workers; women from inner urbancommunities with ease of access to medical clinics; traditional birth attendants whoare formally untrained but highly specialised and practised mainly in remote communities;and Western-trained medical clinicians (obstetricians and midwives). I invitedall the participants to comment on what constituted a ‘good birth’. In this article, Ishow that participants interpreted this variously according to how they believed theuncertainties of childbirth could be managed. Objectivist approaches that define risk asan objective reality amenable to quantifiable measurement are thus rendered inadequate.Interpretivist approaches better explain the reality that social actors not only findrisk in different sites but gravitate towards different practices, discourses and individualsthey can trust especially those with whom they feel a strong sense of community.Strategies are, therefore, formed less through scientific rationality but according tofeelings and emotions and the lived experience. The concept of risk cultures conveysthis complexity; they are formed around values rather than calculable rationalities. Riskcultures form self-reflexively to manage contingent circumstances.

A bust but no boom: responses of floodplain bird assemblages during and after prolonged drought

Climate change alters the frequency and severity of extreme events, such as drought. Such events will be increasingly important in shaping communities as climate change intensifies. The ability of species to withstand extreme events (resistance) and to recover once adverse conditions abate (resilience) will determine their persistence. We estimated the resistance and resilience of bird species during and after a 13-year drought (the 'Big Dry') in floodplain forests in south-eastern Australia. We conducted bird surveys at the beginning and end of the Big Dry, and after the abrupt end to the drought (the 'Big Wet'), to evaluate species-specific changes in reporting rates among the three periods. We assessed changes in bird-breeding activity before and after the Big Wet to estimate demographic resilience based on breeding. Between the start and the end of the Big Dry (1998 vs. 2009), 37 of 67 species declined substantially. Of those, only two had increased reporting rates after the Big Wet (2009 vs. 2013) that were equal to or larger than their declines, while three partially recovered. All other declining species showed low resilience: 25 showed no change in reporting rates and seven declined further. The number of breeding species and total breeding activity of all species declined after the Big Wet, and there was no change in the number of young produced. The Big Dry caused widespread declines in the floodplain avifauna. Despite the drought being broken by 2 years of well-above-average rainfall and subsequent near-average rainfall, most species showed low resilience and there was little indication that overall breeding had increased. The effects of drought appeared to be pervasive for much of the floodplain avifauna, regardless of species traits (species body mass, fecundity, mobility or diet). Ecosystems such as these are likely to require active management and restoration, including reinstatement of natural flooding regimes, to improve ecological condition, to enhance resistance and resilience to extreme climate events.
