The effectiveness of national-level containment and closure policies across income levels during the COVID-19 pandemic: an analysis of 113 countries

Despite heterogeneity in income levels, countries implemented similarly strict containment and closure policies to mitigate the COVID-19 pandemic. This research assesses the effectiveness of these containment and closure policies, which we defined as larger decreases in mobility and smaller COVID-19 case and death growth rates. Using daily data for 113 countries on mobility and cumulative COVID-19 case and death counts over the 130 days between February 15, 2020 and June 23, 2020, we examined changes in mobility, morbidity, and mortality growth rates across the World Bank’s income group classifications. Containment policies correlated with the largest declines in mobility in higher income countries. High-income countries also achieved lower COVID-19 case and death growth rates than low-income countries. This study finds better epidemiological outcomes of containment and closure policies for higher income countries than lower income countries. These findings urge policymakers to consider contextual differences, including levels of economic activity and the structure of the economy, when crafting policies in response to public health emergencies

An empirical evaluation of models of text document similarity

Modeling the semantic similarity between text documents presents a significant theoretical challenge for cognitive science, with ready-made applications in information handling and decision support systems dealing with text. While a number of candidate models exist, they have generally not been assessed in terms of their ability to emulate human judgments of similarity. To address this problem, we conducted an experiment that collected repeated similarity measures for each pair of documents in a small corpus of short news documents. An analysis of human performance showed inter-rater correlations of about 0.6. We then considered the ability of existing models—using wordbased, n-gram and Latent Semantic Analysis (LSA) approaches—to model these human judgments. The best performed LSA model produced correlations of about 0.6, consistent with human performance, while the best performed word-based and n-gram models achieved correlations closer to 0.5. Many of the remaining models showed almost no correlation with human performance. Based on our results, we provide some discussion of the key strengths and weaknesses of the models we examined

Doing away with the drab age

This article surveys recent developments in the study of mid-Tudor literature; some of the problems the area has traditionally faced and still faces; and the opportunities for new research it offers, especially that which exploits new technology. It traces the deleterious effect that C. S. Lewis’ epithet ‘Drab Age’ has had upon the field, and how this has been compounded by institutional and market pressures in university education and academic publishing in the second half of the twentieth century. Nonetheless, interest in mid-16th century literature is being revived by historicist readings. The article maps out a number of areas ripe for future study, including life-writing, women’s writing, miscellanies, anonymous writing, cheap/ephemeral print, Inns of Court writing, translation, Tudor poetics, manuscripts, non-dramatic dialogue, paratext and anthologies of ‘tragical tales’. It calls for an unprejudiced reassessment of the aesthetics of mid-Tudor literature and draws attention to its humour and generic hybridity

The development of national competency standards for the midwife in Australia

Objective: to develop and validate national competency standards for midwives in Australia. This study was part of a commissioned national research project to articulate the scope of practice of Australian midwives and to develop national competency standards to assist midwives to deliver safe and competent midwifery care. Design: a multi-method, staged approach was used to collect data through a literature review, workshop consultations, interviews, surveys and written submissions in order to develop national competency standards for Australian midwives. Subsequently, direct observation of practice in a range of settings ensured validation of the competencies. Setting: maternity-care settings in each state and territory in Australia. Participants: midwives, other health professionals and consumers of midwifery care. Findings: The national competency standards for the midwife were developed through research and consultation before being validated in practice. Key conclusions: the national competency standards are currently being implemented into education, regulation and practice in Australia. These will be minimum competency standards required of all midwives who seek authority to practise as a midwife in Australia. It is expected that all midwives will demonstrate that they are able to meet the competency standards relevant to the position they hold. Implications for practice: the competency standards establish a national standard for midwives and reinforce responsibility and accountability in the provision of quality midwifery care through safe and effective practice. In addition, individual midwives may use the competency standards as the basis of their ongoing professional development plans. © 2006 Elsevier Ltd. All rights reserved

Sono, estresse e comportamentos compensatórios por enfermeiras e parteiras australianas

OBJECTIVE: To describe sleep, stress and compensatory behaviors in nurses and midwives. METHODS: The study included 41 midwives and 21 nurses working in Australian hospitals between 2005 and 2009. Participation was voluntary. All participants recorded on a daily basis their work and sleep hours, levels of stress and exhaustion, caffeine intake and use of sleep aids for a month (1,736 days, 1,002 work shifts). RESULTS: Participants reported moderate to high levels of stress and exhaustion on 20-40% of work days; experienced sleep disruption on more than 50% of work days; struggled to remain awake on 27% of work days; and suffered extreme drowsiness or experienced a near accident while travelling home on 9% of workdays. Age, perceived sleep duration and work hours were significant predictors of caffeine intake. About 60% of participants reported using sleep aids (about 20% reported taking prescription medications and 44% of nurses and 9% of midwives reported alcohol use as a sleep aid at least once during the study). Stress and workdays were significant predictors of sedative use. Overall, 22% reported being indifferent or mildly dissatisfied with their job. CONCLUSIONS: Sleep problems, high levels of stress and exhaustion and low job satisfaction are prevalent among nurses and midwives. The use of alcohol and sleeping pills as sleep aids, and the use of caffeine to help maintain alertness is also common. Nurses and midwives may use caffeine to compensate for reduced sleep, especially on workdays, and sleeping pills to cope with their daily work-related stress.OBJETIVO: Describir sueño, estrés y comportamientos compensatorios en enfermeras y parteras. MÉTODOS: El estudio incluyó 41 enfermeras 21 parteras en hospitales australianos de 2005 a 2009. La participación fue voluntaria. Los participantes registraron diariamente las horas de trabajo, sueño, estrés y niveles de agotamiento, cafeína y uso de ayuda para dormir durante un mes (1.736 días, 1.002 turnos). RESULTADOS: Los participantes relataron de moderados a elevados niveles de estrés y de agotamiento en 20%-40% de los días de trabajo; experimentaron disturbios del sueño en más de 50% de los días de trabajo; relataron esfuerzo para permanecer despierto en 27% de los días de trabajo; y sofrieron somnolencia extrema o accidente cerca de casa en 9% de los días de trabajo. Edad, duración del sueño percibido y jornadas fueron predictores significativos de la ingestión de cafeína. Aproximadamente 60% de los participantes relataron utilizar la ayuda para dormir: cerca de 20% usaron de medicación prescripta y 44% de las enfermeras y 9% de las parteras consumirán alcohol como auxilio para dormir al menos una vez durante el estudio. Estrés y días de trabajo fueron predictores significativos del uso de sedativos. En general, 22% relataron ser indiferente, o ligeramente insatisfecho con su trabajo. CONCLUSIONES: Problemas en el sueño, estrés y agotamiento elevados y disminución en la satisfacción en el trabajo son prevalecientes. Uso de alcohol y de medicamentos para dormir, y consumo de cafeína para mantenerse alerta también es común. Enfermeras y parteras pueden usar la cafeína para compensar la reducción del sueño, especialmente en días de trabajo, y usar somníferos para compensar el estrés diario.OBJETIVO: Descrever sono, estresse e comportamentos compensatórios em enfermeiras e parteiras.

The role of the midwife in Australia: views of women and midwives

Objective: to research the role of midwives in Australia from the perspectives of women and midwives. This study was part of a commissioned national research project to articulate the scope of practice of Australian midwives and to develop national competency standards to assist midwives to deliver safe and competent midwifery care. Design: a multi-method approach with qualitative data collected from surveys with women and interviews with midwives. Setting: participants represented each state and territory in Australia. Participants: midwives who were randomly selected by the regulatory authorities across the country and women who were consumers of midwifery care and involved in maternity activism. Key conclusions: midwives and women identified a series of key elements that were required of a midwife. These included: being woman centred; providing safe and supportive care; and working in collaboration with others when necessary. These findings were consistent with much of the international literature. Implications for practice: a number of barriers to achieving the full role of the midwife were identified. These included a lack of opportunity to practice across the full spectrum of maternity care, the invisibility of midwifery in regulation and practice, the domination of medicine, workforce shortages, the institutional system of maternity care, and the lack of a clear image of what midwifery is within the wider community. These barriers must be addressed if midwives in Australia are to be able to function according to the full potential of their role. © 2007

Development and validation of an individual-based state-transition model for the prediction of frailty and frailty-related events

Frailty is a biological syndrome that is associated with increased risks of morbidity and mortality. To assess the value of interventions to prevent or manage frailty, all important impacts on costs and outcomes should be estimated. The aim of this study is to describe the development and validation of an individual-based state transition model that predicts the incidence and progression of frailty and frailty-related events over the remaining lifetime of older Australians. An individual-based state transition simulation model comprising integrated sub models that represent the occurrence of seven events (mortality, hip fracture, falls, admission to hospital, delirium, physical disability, and transitioning to residential care) was developed. The initial parameterisation used data from the Survey of Health, Ageing, and Retirement in Europe (SHARE). The model was then calibrated for an Australian population using data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey. The simulation model established internal validity with respect to predicting outcomes at 24 months for the SHARE population. Calibration was required to predict longer terms outcomes at 48 months in the SHARE and HILDA data. Using probabilistic calibration methods, over 1,000 sampled sets of input parameter met the convergence criteria across six external calibration targets. The developed model provides a tool for predicting frailty and frailty-related events in a representative community dwelling Australian population aged over 65 years and provides the basis for economic evaluation of frailty-focussed interventions. Calibration to outcomes observed over an extended time horizon would improve model validity.Aubyn Pincombe, Hossein Haji Ali Afzali, Renuka Visvanathan, Jonathan Karno

Ten steps or climbing a mountain: A study of Australian health professionals' perceptions of implementing the baby friendly health initiative to protect, promote and support breastfeeding

Background: The Baby Friendly Hospital (Health) Initiative (BFHI) is a global initiative aimed at protecting, promoting and supporting breastfeeding and is based on the ten steps to successful breastfeeding. Worldwide, over 20,000 health facilities have attained BFHI accreditation but only 77 Australian hospitals (approximately 23%) have received accreditation. Few studies have investigated the factors that facilitate or hinder implementation of BFHI but it is acknowledged this is a major undertaking requiring strategic planning and change management throughout an institution. This paper examines the perceptions of BFHI held by midwives and nurses working in one Area Health Service in NSW, Australia. Methods: The study used an interpretive, qualitative approach. A total of 132 health professionals, working across four maternity units, two neonatal intensive care units and related community services, participated in 10 focus groups. Data were analysed using thematic analysis. Results: Three main themes were identified: ‘Belief and Commitment’; ‘Interpreting BFHI’ and ‘Climbing a Mountain’. Participants considered the BFHI implementation a high priority; an essential set of practices that would have positive benefits for babies and mothers both locally and globally as well as for health professionals. It was considered achievable but would take commitment and hard work to overcome the numerous challenges including a number of organisational constraints. There were, however, differing interpretations of what was required to attain BFHI accreditation with the potential that misinterpretation could hinder implementation. A model described by Greenhalgh and colleagues on adoption of innovation is drawn on to interpret the findings. Conclusion: Despite strong support for BFHI, the principles of this global strategy are interpreted differently by health professionals and further education and accurate information is required. It may be that the current processes used to disseminate and implement BFHI need to be reviewed. The findings suggest that there is a contradiction between the broad philosophical stance and best practice approach of this global strategy and the tendency for health professionals to focus on the ten steps as a set of tasks or a checklist to be accomplished. The perceived procedural approach to implementation may be contributing to lower rates of breastfeeding continuation

Welshness in British Wales: Negotiating national identity at the margins

Popular interpretations of national identity often focus on the unifying qualities of nationhood. However, societies frequently draw hierarchical distinctions between the people and places who are ‘most national’, and those who are ‘least national’. Little attention is paid to these marginal places within the nation and the experiences of their inhabitants. This article helps to address this by analysing the ‘less Welsh’ British Wales region of Wales, a country that has traditionally possessed a hierarchical, regionally constituted nationhood. The article studies the British Wales region both ‘from above’ – considering how some areas develop as ‘less national’ – and ‘from below’, introducing empirical ethnographic work into ‘everyday Welshness’ in this area. Whilst previous work on hierarchical nationhood focuses on how hierarchies are institutionalized by the state, this article demonstrates how people at the margins of the nation actively negotiate their place in the nation. Whilst people in this area expressed a strong Welshness, they also struggled to place themselves in the nation because they had internalized their lowly place within the national hierarchy. The article demonstrates the importance of place and social class for national identity construction and draws attention to the role of power in the discursive construction of hierarchical nationhood
