Participatory monitoring in community-based fisheries management through a gender lens
Publisher: Springer Science and Business Media LLC
Date: 20-09-2023
DOI: 10.1007/S13280-022-01783-3
Abstract: In small-scale fisheries management, the significance of participation is widely recognised but we are still learning how this can be better operationalised to include different groups, such as women or Indigenous peoples. Participatory monitoring is one tool which has been used to increase participation in fisheries management. The aim of this review is to use critical interpretive synthesis to examine the literature on participatory monitoring within community-based fisheries management from a gender perspective. The synthesis identified and discussed several key areas: reasons presented in the literature for engaging with the themes of gender or participatory monitoring, gendered aspects of participatory monitoring, knowledge valuation and prioritisation in management, replicability and transparency of programme or research methods, and marginalisation narratives. Our findings show the complexities of conducting gender-aware participatory monitoring. Participatory monitoring has the potential to be a transformative and empowering process if the power dynamics involved are considered and addressed.
Untangling Tales of Tropical Sardines: Local Knowledge From Fisheries in Timor-Leste
Publisher: Frontiers Media SA
Date: 13-05-2021
DOI: 10.3389/FMARS.2021.673173
Abstract: Tropical sardines (Family Clupeidae) are an important component of many marine fisheries in the Indo-West Pacific region. In Timor-Leste, a small, less-developed country within this region, ‘sardiña’ are some of the more commonly caught and consumed fish. Yet there is little published information from Timor-Leste about the species composition of these fisheries, nor their biology or ecology. We document the knowledge of Timorese fishers on nine locally distinguished sardine types that contribute to fisheries, and relate these to at least nine species: four species of ‘Flat-bodied Sardinellas’ ( Sardinella subg. Clupeonia spp.), one species of ‘Round-bodied Sardinella’ ( Sardinella subg. Sardinella lemuru ), two species of ‘Tropical Pilchards’ ( Amblygaster spp.) and a ‘Tropical Herring’ species ( Herklotsichthys quadrimaculatus ), all from the Clupeidae family and one Dussumieria species from the Dussumieriidae family. We record variations in local sardine names across the country and document aspects of fishers’ knowledge relevant to understanding and managing the fisheries, including local sardine species’ seasonality, habitat, movements, interannual variation, as well as post-harvest characteristics in relation to perishability. In general, local names relate more closely with groups of species than in idual species, although some names also distinguish fish size within species-groups. The local knowledge identified in this study has immediate application to inform fisheries monitoring and management, and to identify areas for future research. Notably, Timorese fishers recognize and make use of the strong association between some sardine species-groups and seasonally turbid river plumes. While further research is required to understand the underlying mechanisms of this association, this emphasizes the need to consider coastal fisheries and fisher livelihood impacts when assessing any plans or proposals that may alter river flow or water quality. Fishers also recognize migratory behavior of some sardine species, in particular the Flat bodied Sardinellas ( S. gibbosa and others) along the north-west coast of Timor-Leste and across the border into Indonesian West Timor. Such insights complicate and need to be accounted for in initiatives for co-management or community-based management of Timor-Leste’s coastal waters and their fisheries.
The predicted impact of HPV vaccination on male infections and male HPV-related cancers in Australia
Publisher: Elsevier BV
Date: 11-2011
DOI: 10.1016/J.VACCINE.2011.02.091
Abstract: Australia implemented a National HPV Vaccination Program in 2007, with routine vaccination of 12-13 year old females and catch-up in females aged 13-26 years to 2009. The aim of this study was to estimate the impact of the current female-only national vaccination program on males, and then to estimate the incremental benefits to males from being included in the program. We used preliminary data to estimate vaccination coverage in females. We then fitted a dynamic model of sexual behaviour and HPV transmission in Australia to local data on female pre-vaccination age-specific HPV prevalence, predicted the corresponding pre-vaccination prevalence in males due to heterosexual transmission, and modelled the short and long term impact of female-only versus female-and-male vaccination programs. The estimated 3-dose female coverage rates were 78% (range 70-80%) for ongoing coverage in 12-13 year old girls and from 74% (range 70-80%) in 14 year olds, to 25% (range 15-35%) for women aged 26 years old in 2007. The median estimate for age-standardised pre-vaccination HPV 16 prevalence in females and males aged 15-59 years was 3.2% (95% range: 2.4-4.1%) and 3.1% (95% range: 2.2-4.2%), respectively. The current program in females is predicted to result in a 68% reduction in male HPV 16 infections by 2050, leading to an estimated long term reduction of 14% in rates of cancers of the head, neck and anogenital area. The estimated proportion of the maximum possible vaccine-conferred benefit to males from a female-and-male program which will be achieved by female-only vaccination is 73% (range in probabilistic sensitivity analysis: 53-78%). In conclusion, up to three-quarters of the maximum possible vaccination-conferred benefit to males due to reduced heterosexual transmission will be achieved by the existing female-only program.

Expenditure and resource utilisation for cervical screening in Australia
Publisher: Springer Science and Business Media LLC
Date: 12-2012
Abstract: The National Cervical Screening Program in Australia currently recommends that women aged 18–69 years are screened with conventional cytology every 2 years. Publicly funded HPV vaccination was introduced in 2007, and partly as a consequence, a renewal of the screening program that includes a review of screening recommendations has recently been announced. This study aimed to provide a baseline for such a review by quantifying screening program resource utilisation and costs in 2010. A detailed model of current cervical screening practice in Australia was constructed and we used data from the Victorian Cervical Cytology Registry to model age-specific compliance with screening and follow-up. We applied model-derived rate estimates to the 2010 Australian female population to calculate costs and numbers of colposcopies, biopsies, treatments for precancer and cervical cancers in that year, assuming that the numbers of these procedures were not yet substantially impacted by vaccination. The total cost of the screening program in 2010 (excluding administrative program overheads) was estimated to be A$194.8M. We estimated that a total of 1.7 million primary screening smears costing $96.7M were conducted, a further 188,900 smears costing $10.9M were conducted to follow-up low grade abnormalities, 70,900 colposcopy and 34,100 histological evaluations together costing $21.2M were conducted, and about 18,900 treatments for precancerous lesions were performed (including retreatments), associated with a cost of $45.5M for treatment and post-treatment follow-up. We also estimated that $20.5M was spent on work-up and treatment for approximately 761 women diagnosed with invasive cervical cancer. Overall, an estimated $23 was spent in 2010 for each adult woman in Australia on cervical screening program-related activities. Approximately half of the total cost of the screening program is spent on delivery of primary screening tests but the introduction of HPV vaccination, new technologies, increasing the interval and changing the age range of screening is expected to have a substantial impact on this expenditure, as well as having some impact on follow-up and management costs. These estimates provide a benchmark for future assessment of the impact of changes to screening program recommendations to the costs of cervical screening in Australia.

Recent trends of forest cover change and ecosystem services in eastern upland region of Bangladesh
Publisher: Elsevier BV
Date: 2019
DOI: 10.1016/J.SCITOTENV.2018.07.406
Abstract: Forest cover changes have erse outcomes for the livelihoods of rural people across the developing world. However, these outcomes are poorly characterized across varying landscapes. This study examined forest cover changes, associated drivers, and impacts on ecosystem services supporting livelihoods in three distinct areas (i.e. remote, intermediate and on-road) in the Chittagong Hill Tracts region of Bangladesh. The three zones had features of decreasing distance to major roads, decreasing levels of forest cover, and increasing levels of agricultural change. Data was collected from satellite images for 1989-2014, structured household interviews, and group discussions using Participatory Rural Appraisal approaches with local communities to integrate and contrast local people's perceptions of forest cover and ecosystem service change with commonly used methods for mapping forest dynamics. Satellite image analysis showed a net gain of forest areas from 1989 to 2003 followed by a net loss from 2003 to 2014. The gain was slightly higher in intermediate (1.68%) and on-road (1.33%) zones than in the remote (0.5%) zone. By contrast, almost 90% of households perceived severe forest loss and 75% of respondents observed concomitant declines in the availability of fuel wood, construction materials, wild foods, and fresh water. People also reported traveling further from the household to harvest forest products. The main drivers of forest loss identified included increased harvesting of timber and fuel wood over time in the intermediate and on-road zones, whereas swidden farming persisted as the major driver of change over time in the remote zone. The contrast between remotely-sensed forest gains and household-perceived forest loss shows community experiences may be a critical addition to satellite imagery analysis by revealing the livelihood outcomes linked to patterns of forest loss and gain. Community experiences may also evoke solutions by characterizing local drivers of forest change. Failing to disaggregate the impacts of forest loss and gains on ecosystems services over time may lead to uninformed management and further negative consequences for human well-being.

Cancer incidence and mortality in people aged less than 75 years: Changes in Australia over the period 1987–2007
Publisher: Elsevier BV
Date: 12-2013
DOI: 10.1016/J.CANEP.2013.09.010
Abstract: Australia has one of the highest rates of cancer incidence worldwide and, despite improving survival, cancer continues to be a major public health problem. Our aim was to provide simple summary measures of changes in cancer mortality and incidence in Australia so that progress and areas for improvement in cancer control can be identified. We used national data on cancer deaths and newly registered cancer cases and compared expected and observed numbers of deaths and cases diagnosed in 2007. The expected numbers were obtained by applying 1987 age-sex specific rates (average of 1986-1988) directly to the 2007 population. The observed numbers of deaths and incident cases were calculated for 2007 (average of 2006-2008). We limited the analyses to people aged less than 75 years. There was a 28% fall in cancer mortality (7827 fewer deaths in 2007 vs. 1987) and a 21% increase in new cancer diagnoses (13,012 more diagnosed cases in 2007). The greatest reductions in deaths were for cancers of the lung in males (-2259), bowel (-1797), breast (-773) and stomach (-577). Other notable falls were for cancers of the prostate (-295), cervix (-242) and non-Hodgkin lymphoma (-240). Only small or no changes occurred in mortality for cancers of the lung (female only), pancreas, brain and related, oesophagus and thyroid, with an increase in liver cancer (267). Cancer types that showed the greatest increase in incident cases were cancers of the prostate (10,245), breast (2736), other cancers (1353), melanoma (1138) and thyroid (1107), while falls were seen for cancers of the lung (-1705), bladder (-1110) and unknown primary (-904). The reduction in mortality indicates that prevention strategies, improvements in cancer treatment, and screening programmes have made significant contributions to cancer control in Australia since 1987. The rise in incidence is partly due to diagnoses being brought forward by technological improvements and increased coverage of screening and early diagnostic testing.
A revision of sexual mixing matrices in models of sexually transmitted infection
Publisher: Wiley
Date: 30-07-2012
DOI: 10.1002/SIM.5545
Abstract: Two sexual mixing matrices previously used in models of sexually transmitted infections (STIs) are intended to calculate the probability of sexual interaction between age groups and sexual behaviour subgroups. When these matrices are used to specify multiple criteria for how people select sexual partners (such as age group and sexual behaviour class), their conditional probability structure means that they have in practice been prone to misuse. We constructed revised mixing matrices that incorporate a corrected conditional probability structure and then used one of them to examine the effect of this revision on population modelling of STIs. Using a dynamic model of human papillomavirus (HPV) transmission as an ex le, we examined changes to estimates of HPV prevalence and the relative reduction in age-standardised HPV incidence after the commencement of publicly funded HPV vaccination in Australia. When all other model specifications were left unchanged, the revised mixing matrix initially led to estimates of age-specific oncogenic HPV prevalence that were up to 11% higher than our previous models at certain ages. After re-calibrating the model by modifying unobservable parameters characterising HPV natural history, the revised mixing matrix yielded similar estimates to our previous models, predicting that vaccination would lead to relative HPV incidence reductions of 43% and 85% by 2010 and 2050, respectively, compared with 43% and 86% using the unrevised mixing matrix formulation. Our revised mixing matrix offers a rigorous alternative to commonly used mixing matrices, which can be used to reliably and explicitly accommodate conditional probabilities, with appropriate re-calibration of unobservable model parameters.

Evaluation of primary HPV-DNA testing in relation to visual inspection methods for cervical cancer screening in rural China: an epidemiologic and cost-effectiveness modelling study
Publisher: Springer Science and Business Media LLC
Date: 13-06-2011
Abstract: A new lower-cost rapid-throughput human papillomavirus (HPV) test ( care HPV, Qiagen, Gaithersburg, USA) has been shown to have high sensitivity for the detection of high grade cervical intraepithelial neoplasia. We assessed the outcomes and cost-effectiveness of care HPV screening in rural China, compared to visual inspection with acetic acid, when used alone (VIA) or in combination with Lugol's iodine (VIA/VILI). Using data on sexual behaviour, test accuracy, diagnostic practices and costs from studies performed in rural China, we estimated the cost-effectiveness ratio (CER) and associated lifetime outcomes for once-lifetime and twice-lifetime screening strategies, and for routine screening at 5-yearly, 10-yearly and IARC-recommended intervals. The optimal age range for once-lifetime screening was also assessed. For all strategies, the relative ordering of test technologies in reducing cervical cancer incidence and mortality was VIA (least effective) VIA/VILI care HPV@1.0 pg/ml and care HPV@0.5 pg/ml (most effective). For once-lifetime strategies, maximum effectiveness was achieved if screening occurred between 35-50 years. Assuming a participation rate of ~70%, once-lifetime screening at age 35 years would reduce cancer mortality by 8% (for VIA) to 12% (for care HPV@0.5) over the long term, with a CER of US$557 (for VIA) to $959 (for care HPV@1.0) per life year saved (LYS) compared to no intervention referenced to a 2008 GDP per capita in Shanxi Province of $2,975. Correspondingly, regular screening with an age-standardised participation rate of 62% (which has been shown to be achievable in this setting) would reduce cervical cancer mortality by 19-28% (for 10-yearly screening) to 43-54% (using IARC-recommended intervals), with corresponding CERs ranging from $665 (for 10-yearly VIA) to $2,269 (for IARC-recommended intervals using care HPV@1.0) per LYS. This modelled analysis suggests that primary care HPV screening compares favourably to visual inspection screening methodologies in rural China, particularly if used as part of a regular screening program.

DOI: 10.1016/J.JENVMAN.2011.06.013
Abstract: In this study, we explored the use of selected visual techniques (e.g. video, photography, diagramming) in facilitating learning among Indigenous communities living in remote protected areas at sites in Vietnam and Australia. The techniques were employed during interviews and workshops aimed at accessing and enhancing local peoples' perspectives on their landscape and on specific natural resource management issues. The effectiveness of the different techniques for enabling learning varied markedly with the context, highlighting the need for facilitator skill and flexibility in application of techniques. Visual techniques helped to engage participants encourage unrestrained and lateral thinking provide opportunities for self-expression and reflection and to expose participants to perspectives of other community members. Valuable insights emerged on broad aspects of learning and these were incorporated into a simple model that highlights three types of conceptualisation found to be important in these processes.

Cervical cancer screening in Australia: Modelled evaluation of the impact of changing the recommended interval from two to three years
Publisher: Springer Science and Business Media LLC
Date: 26-11-2010
Abstract: The National Cervical Screening Program in Australia currently recommends that sexually active women between the ages of 18-70 years attend routine screening every 2 years. The publically funded National HPV Vaccination Program commenced in 2007, with catch-up in females aged 12-26 years conducted until 2009 and this may prompt consideration of whether the screening interval and other aspects of the organized screening program could be reviewed. The aim of the current evaluation was to assess the epidemiologic outcomes and cost implications of changing the recommended screening interval in Australia to 3 years. We used a modelling approach to evaluate the effects of moving to a 3-yearly recommended screening interval. We used data from the Victorian Cervical Cytology Registry over the period 1997-2007 to model compliance with routine screening under current practice, and registry data from other countries with 3-yearly recommendations to inform assumptions about future screening behaviour under two alternative systems for screening organisation - retention of a reminder-based system (as in New Zealand), or a move to a call-and-recall system (as in England). A 3-yearly recommendation is predicted to be of similar effectiveness to the current 2-yearly recommendation, resulting in no substantial change to the total number of incident cervical cancer cases or cancer deaths, or to the estimated 0.68% average cumulative lifetime risk of cervical cancer in unvaccinated Australian women. However, a 3-yearly screening policy would be associated with decreases in the annual number of colposcopy and biopsy procedures performed (by 4-10%) and decreases in the number of treatments for pre-invasive lesions (by 2-4%). The magnitude of the decrease in the number of diagnostic procedures and treatments would depend on the method of screening organization, with call-and-recall screening associated with the highest reductions. The cost savings are predicted to be of the order of A$10-18 M annually, equivalent to 6-11% of the total cost of the current program (excluding overheads), with call-and-recall being associated with the greatest savings. Lengthening the recommended screening interval to 3 years in Australia is not predicted to result in increases in rates of cervical cancer and is predicted to decrease the number of women undergoing diagnostic and treatment procedures. These findings are consistent with a large body of international evidence showing that screening more frequently than every three years with cervical cytology does not result in substantial gains in screening effectiveness.

Fall in Genital Warts Diagnoses in the General and Indigenous Australian Population Following Implementation of a National Human Papillomavirus Vaccination Program: Analysis of Routinely Collected Nat
Publisher: Oxford University Press (OUP)
Date: 12-08-2014
Abstract: Human papillomavirus (HPV) vaccination targeting females aged 12-13 years commenced in Australia in 2007, with catch-up vaccination of females aged 13-26 years continuing to 2009. Whole-population analyses, including effects on the Indigenous population, have not previously been reported. All hospital admissions between 1999-2011 involving a diagnosis of genital warts were obtained from a comprehensive national database. We compared the age-specific rates before to those after implementation of the vaccination program, according to sex and other characteristics. Admission rates decreased from mid-2007 in females aged 12-17 years (annual decline, 44.1% [95% confidence interval {CI}, 35.4%-51.6%]) and from mid-2008 in females and males aged 18-26 years (annual declines, 31.8% [95% CI, 28.4%-35.2%] and 14.0% [95% CI, 5.1%-22.1%], respectively). The overall reductions from 2006-2007 to 2010-2011 were 89.9% (95% CI, 84.4%-93.4%) for females aged 12-17 years, 72.7% (95% CI, 67.0%-77.5%) for females aged 18-26 years, and 38.3% (95% CI, 27.7%-47.2%) for males aged 18-26 years. Compared with the average annual number before program implementation, about 1000 fewer hospital admissions involved a warts diagnosis during 2010-2011. Reductions after program implementation were similar for Indigenous (86.7% [95% CI, 76.0-92.7]) and non-Indigenous (76.1% [95% CI, 71.6%-79.9%]) females aged 15-24 years (P(heterogeneity) = .08). National population-based hospital data confirm previous clinic-based reports of a marked decline in genital warts diagnoses among young people in Australia after program implementation, including indirect benefits to males. The impact of HPV vaccination appears to be similar in young Indigenous and non-Indigenous females.

Cost-effectiveness and equity impacts of three HPV vaccination programmes for school-aged girls in New Zealand
Publisher: Elsevier BV
Date: 05-2014
DOI: 10.1016/J.VACCINE.2014.02.071
Abstract: As with many high-income countries, vaccination coverage against human papilloma virus (HPV) infection is not high in New Zealand (NZ) at 47% in school-aged girls for three doses. We estimate the health gains, net-cost and cost-effectiveness of the currently implemented HPV national vaccination programme of vaccination dispersed across schools and primary care, and two alternatives: school-based only (assumed coverage as per Australia: 73%), and mandatory school-based vaccination but with opt-out permitted (coverage 93%). We also generate estimates by social group (sex, ethnic and deprivation group). A Markov macro-simulation model was developed for 12-year-old girls and boys in 2011, with future health states of: cervical cancer, pre-cancer (CIN I-III), genital warts, and three other HPV-related cancers (oropharyngeal, anal, vulvar cancer). In each state health sector costs, including additional health sector costs from extra life, and quality-adjusted life years (QALYs) were accumulated. The current HPV vaccination programme has an estimated cost-effectiveness of NZ$18,800/QALY gained (about US$9700/QALY gained using the OECD's purchasing power parities 95% UI: US$6900 to $33,700) compared to the status quo in NZ prior to 2008 (no vaccination, screening alone). The incremental cost-effectiveness ratio (ICER) of an intensive school-based only programme of girls, compared to the current situation, was US$33,000/QALY gained. Mandatory vaccination appeared least cost-effective (ICER compared to school-based of US$117,000/QALY gained, but with wide 95% uncertainty limits from $56,000 to $220,000). All interventions generated more QALYs per 12-year-old for Māori (indigenous population) and people living in deprived areas (range 5-25% greater QALYs gained). A more intensive school-only vaccination programme seems warranted. Reductions in vaccine price will greatly improve cost-effectiveness of all options, possibly making a law for mandatory vaccination optimal from a health sector perspective. All interventions could reduce ethnic and socioeconomic disparities in HPV-related disease.
MAVARIC - a comparison of automation-assisted and manual cervical screening: a randomised controlled trial.
Publisher: National Institute for Health and Care Research
Date: 2011
DOI: 10.3310/HTA15030
Abstract: The principal objective was to compare automation-assisted reading of cervical cytology with manual reading using the histological end point of cervical intraepithelial neoplasia grade II (CIN2) or worse (CIN2+). Secondary objectives included (i) an assessment of the slide ranking facility of the Becton Dickinson (BD) FocalPoint™ Slide Profiler (Becton Dickinson, Franklin Lakes, NJ, USA), especially 'No Further Review', (ii) a comparison of the two approved automated systems, the ThinPrep® Imaging System (Hologic, Bedford, MA, USA) and the BD FocalPoint Guided Screener Imaging System, and (iii) automated versus manual in terms of productivity and cost-effectiveness. A 1 : 2 randomised allocation of slides to either manual reading or automation-assisted paired with manual reading. Cytoscreeners were blinded to whether s les would be read only manually or manually paired with automated. Slide reading procedures followed real-life laboratory protocol to produce a final result and, for paired readings, the worse result determined the management. Costs per event were estimated and combined with productivity to produce a cost per slide, per woman and per CIN2+ and cervical intraepithelial neoplasia grade III (CIN3) or worse (CIN3+) lesion detected. Cost-effectiveness was estimated using cost per CIN2+ detected. Lifetime cost-effectiveness in terms of life-years and quality-adjusted life-years was estimated using a mathematical model. Liquid-based cytology s les were obtained in primary care, and a small number of abnormal s les were obtained from local colposcopy clinics, from different women, in order to enrich the proportion of abnormals. All of the s les were read in a single large service laboratory. Liquid residues used for human papillomavirus (HPV) triage were tested (with Hybrid Capture 2, Qiagen, Crawley, UK) in a specialist virology laboratory in Edinburgh, UK. Histopathology was read by a specialist gynaecological pathology team blinded to HPV results and type of reading. S les were obtained from women aged 25-64 years undergoing primary cervical screening in Greater Manchester, UK, with small proportions from women outside this age range and from women undergoing colposcopy. The principal intervention was automation-assisted reading of cervical cytology slides which was paired with a manual reading of the same slide. Low-grade cytological abnormalities (borderline and mild dyskaryosis) were triaged with HPV testing to direct colposcopy referral. Women with high-grade cytology were referred for colposcopy and those with negative cytology were returned to recall. The principal outcome measure was the sensitivity of automation-assisted reading relative to manual for the detection of CIN2+. A secondary outcome measure was cost-effectiveness of each type of reading to detect CIN2+. The study was powered to detect a relative sensitivity difference equivalent to an absolute difference of 5%. The principal finding was that automated reading was 8% less sensitive relative to manual, 6.3% in absolute terms. 'No further review' was very reliable and, if restricted to routine screening s les, < 1% of CIN2+ would have been missed. Automated and manual were very similar in terms of cost-effectiveness despite a 60%-80% increase in productivity for automation-assisted reading.

Community perspectives on delivering trauma-aware and culturally safe perinatal care for Aboriginal and Torres Strait Islander parents
Publisher: Elsevier BV
Date: 03-2023
DOI: 10.1016/J.WOMBI.2022.07.174
Abstract: Since colonisation, Aboriginal and Torres Strait Islander peoples have experienced violence, loss of land, ongoing discrimination and increased exposure to traumatic events. These include adverse childhood experiences which can lead to complex trauma, and are associated with increased incidence of high-risk pregnancies, birth complications and emergence of post-traumatic symptoms during the perinatal period, potentially impacting parenting and leading to intergenerational trauma. The perinatal period offers unique opportunities for processing experiences of trauma and healing yet can also be a time when parents experience complex trauma-related distress. Therefore, it is essential that trauma-aware culturally safe perinatal care is accessible to Aboriginal and Torres Strait Islander parents. This study aimed to understand community perspectives of what 'trauma-aware culturally safe perinatal care' would look like for Aboriginal and Torres Strait Islander parents. Data were collected during a workshop held with predominantly Aboriginal and Torres Strait Islander key stakeholders to co-design strategies to foster trauma-aware culturally safe perinatal care. Data were thematically analysed. Four overarching themes represent proposed goals for trauma-aware culturally safe care: Authentic partnerships that are nurtured and invested in to provide the foundations of care a skilled workforce educated in trauma awareness empowering and compassionate care for building trust and safe and accessible environments to facilitate parent engagement. Provision of trauma-aware culturally safe care achieving these goals is likely to enable parents experiencing complex trauma to access appropriate support and care to foster healing in the critical perinatal period.

Assessing land use changes and livelihood outcomes of rural people in the Chittagong Hill Tracts region, Bangladesh
Publisher: Wiley
Date: 26-10-2021
DOI: 10.1002/LDR.3795
Abstract: Land use change is a pressing concern for the livelihoods of people in tropical developing countries. Changes in land use from swidden (shifting cultivation) agriculture to smallholder tree‐dominated areas producing timber, fruits and cash crops can result in changing livelihood outcomes for rural communities. This paper examines land use patterns of rural households and the association with food production and income across three different zones of various forest proximity across a landscape gradient (remote, intermediate and on‐road) in the Chittagong Hill Tracts region of Bangladesh. We conducted in‐depth semi‐structured surveys of households (175–300) and farm owners (30) to collect information on people's perceptions of land use change, present land use patterns and contributions to food production and income. Our research found that more than half of the surveyed households experienced a decline in the land available for food production over the past 30 years. The land use patterns revealed decreasing crop lands (mainly swidden shifting cultivation/land rotation farms) and an increase in areas of planted trees within this landscape. However, household use of the reduced crop land has not affected food production in the on‐road zone, whereas the ersity of food sources has declined. People living in more remote areas engaged in swidden farming and used larger areas of crop and fallow lands, fruit orchard and accessed natural forest lands that provide a erse reservoir of food sources. The current land uses contribute to variations in annual household income across zones, with remote dwelling people earning less to those living closer to urban areas in the intermediate and on‐road zones. In summary, this transition of land uses over three decades and changes in income and food availability cannot be generalised across the region because of zone specific differences. We recommend a broader and context‐reliant landscape management approach in consideration of the ersity of forest and tree benefits for the livelihoods of people in the region.
Prevention of cervical cancer in rural China: Evaluation of HPV vaccination and primary HPV screening strategies

DOI: 10.1016/J.VACCINE.2010.12.085
Abstract: Comprehensive evaluation of the cost-effectiveness of HPV vaccination in China has not previously been performed. The objective of this study was to evaluate vaccination as an alternative or addition to primary HPV screening with careHPV (Qiagen, Gaithersburg, USA), and to assess the threshold total cost per vaccinated girl (CVG) at which strategies involving vaccination would become viable compared to screening-only strategies in rural China. We used data from field studies in Shanxi Province to support modelling of HPV vaccination and screening, including local information on sexual behaviour, HPV prevalence, test accuracy, treatment protocols and costs. We evaluated several strategies involving screening once or twice per lifetime or at regular 5-yearly intervals, with or without vaccination of young females at age 15 years, assuming 70% coverage for both screening and vaccination. We also predicted cross-sectional cancer incidence each year to the year 2050 for a range of strategies. We found that strategies involving vaccination would be cost-effective at CVGs of US$50-54 or less, but at CVGs >$54, screening-only strategies would be more cost-effective. If vaccination of young cohorts is combined with two rounds of careHPV screening for women aged 30-59 years in 2012 and 2027, a predicted indicative 33% reduction in cervical cancer incidence by 2030 would be sustained until 2050, with incidence rates decreasing thereafter. In conclusion, taking into account estimated vaccine delivery costs (for 3 doses), a per-dose HPV vaccine cost of approximately <$9-14 would be required for strategies involving vaccination to be cost-effective. Overall, combined screening and vaccination approaches are required to maximise outcomes in rural China.

Coping or adapting? Experiences of food and nutrition insecurity in specialised fishing households in Komodo District, eastern Indonesia
Publisher: Springer Science and Business Media LLC
Date: 15-02-2021
DOI: 10.1186/S12889-021-10248-3
Abstract: There is growing recognition of the need for fish to be better integrated into nutrition-sensitive strategies for addressing malnutrition. Fish are overwhelmingly produced by the small-scale sector, which supports food and nutrition security directly through the provision of fish and indirectly through the generation of income which can be used to purchase other desired foods. However, there has been relatively little research on the extent of food and nutrition security in specialised fishing communities. This study assessed food and nutrition security among households in specialised fishing communities in Komodo District, eastern Indonesia. We assessed the seasonal nutrition quality of household diets using the Food Consumption Score for nutritional analysis and food insecurity using the Household Food Insecurity Access Scale in 66 households across three communities, using a modified cluster s ling strategy. We calculated and generated descriptive statistics for these indicators with Microsoft Excel and ran a logistic generalized linear mixed model to determine factors associated with severe food insecurity using SPSS. We used semi-structured interviews and focus group discussions to understand perceptions of, change over time, and strategies for dealing with food shortfalls. While most households have acceptable access to nutritious foods, especially protein and heme iron-rich foods, nearly one half of households consumed vitamin A rich foods on less than 3 days of the 7-day recall period in either season. More than half of households reported experiencing a moderate or severe level of food insecurity, with higher food insecurity in the wet season. Low maternal education (OR: 3.8, 95%CI 1.5–9.9) and lower household wealth (OR: 0.5, 95%CI 0.3–0.9) were found to be associated with a severe level of food insecurity. Household’s consumptive and non-consumptive response strategies reflect adaptation to chronic food insecurity but are nutritionally and economically unsustainable. Households in specialised fishing communities in Komodo District consumed diets with low ersity and experienced high levels of food insecurity. There is a need for culturally-appropriate nutrition-sensitive strategies to enhance food and nutrition security in vulnerable fishing communities.

The predicted impact of vaccination on human papillomavirus infections in Australia
Publisher: Wiley
Date: 13-08-2008
DOI: 10.1002/IJC.23633
Abstract: Vaccines based on human papillomavirus (HPV) 16 and 18 virus-like particles have the potential to prevent approximately 70% of cervical cancers. In Australia, public vaccination against HPV commenced in April 2007, and includes routine vaccination of females aged 12-13 years, and a 2-year school and GP-based catch-up in females aged 12-26 years. The objectives of this study were to estimate initial vaccination coverage rates, to describe current patterns of sexual behavior in young females, and to predict the impact of vaccination on HPV16 infections. We reviewed early coverage data, estimating that coverage in 2007/2008 will reach 86% (feasible range 67-90%) for 12- to 13-year-old girls, with lower rates attained in older females. A review of survey data found that the median age of first intercourse in Australian females is 16 years, with approximately 90% of women sexually active at 22 years. Using these data, we performed an analysis of HPV transmission to predict the impact of vaccination on HPV infection rates. The public program is predicted to result in a reduction in the age-standardized incidence of HPV16 infections of 56% by 2010 (feasible range 48-61%), and 92% by 2050 (feasible range 76-95%). Elective vaccination of older women and vaccination of males may provide some incremental gains, but the benefits to women of vaccinating males will be less if coverage of females remains high. In conclusion, the current vaccination program is expected to result in a substantial and rapid reduction in the incidence of HPV16 in Australia.

Prediction of the Ultimate Strength of Notched and Unnotched IM7/977-3 Laminated Composites Using a Micromechanics Approach
Publisher: MDPI AG
Date: 11-10-2021
Abstract: This paper proposes a multi-scale analysis technique based on the micromechanics of failure (MMF) to predict and investigate the damage progression and ultimate strength at failure of laminated composites. A lamina’s representative volume element (RVE) is developed to predict and calculate constituent stresses. Damages that occurred in the constituents are calculated using separate failure criteria for both fiber and matrix. Subsequently, the volume-based damage homogenization technique is utilized to prevent the localization of damage throughout the total matrix zone. The proposed multiscale analysis procedure is then used to investigate the notched and unnotched behavior of three multi-directional composite layups, [30, 60, 90, −60, 30]2S, [0, 45, 90, −45]2S, and [60, 0, −60]3S, subjected to static tension and compression loading. The specimen is fabricated from unidirectionally reinforced composite (IM7/977-3). The prediction of ultimate strength at failure and equivalent stiffness are then benchmarked against the experimental test data. The comparative analysis with various failure models is also carried out to validate the proposed model. MMF demonstrated the capability to correctly predict the ultimate strength at failure for a range of multidirectional composites laminates under tensile and compressive load. The numerically predicted findings revealed a good agreement with the experimental test data. Out of the three investigated composite layups, the simulated results for the quasi-isotropic [0, 45, 90, −45]2S layup agreed extremely well with the experimental results with all the percentage errors within 10% of the measured failure loads.

Land Use Preference for Ecosystem Services and Well-Being in Chittagong Hill Tracts of Bangladesh
Publisher: MDPI AG
Date: 07-12-2022
DOI: 10.3390/F13122086
Abstract: Researchers increasingly investigate ecosystem services to assess their role in supporting livelihoods, well-being and economic value in order to inform decision-making. Many studies have explored links between ecosystem services and community-based livelihoods, with a very narrow focus on the importance of land use to well-being. We evaluated the value of ecosystem services from various land uses supporting livelihoods and the overall well-being of local communities in the Chittagong Hill Tracts (CHT) of Bangladesh. By applying a participatory habitat valuation approach with the ethnic communities from eight villages, we explored their preferences for, and perceptions of, ecosystem services and their sources in a multi-functional landscape under different land use, i.e., forest, swidden and low-land agriculture, fruit orchard and water bodies, and three land ownership contexts (state, private and mixed ownership on forest lands). Our findings revealed that community land use preference for ecosystem services supports ten different well-being needs. Among others, forests were valued land used for two-thirds of well-being needs, including the provision of shelter, nutrition, primary health care, an adequate supply of potable water, a lower level of ecological stress (i.e., protection from associated landslide soil erosion), cultural and spiritual benefits and livestock foraging. People commonly valued the food, income and nutrition contributions of all land uses. However, different forest and land ownership contexts and rights within the landscape influence people’s preference for ecosystem services from land use in supporting their well-being. People with secure ownership (i.e., private and private-community) showed a broad and positive appreciation for ecosystem services to meet their well-being needs. Our study highlights that local and ethnic people’s land-use preferences and ownership contexts are critical factors in assessing well-being in the context of multifunctional landscapes. We recommend that ecosystem services be considered in future decision-making related to forest and land use to support human well-being.
