    This research examines values education of a home schooling family operating within Australia\u27s education system, including a comparison the National Values Education framework. Home schooling as an alternative form of education is growing rapidly around the world, with current analysis suggesting that there are ten to twenty thousand children undergoing home schooling in Australia. Many parents choose this alternative education out of concern for the values being taught to their children. Research has reinforced the current priority being given to values education as an essential part of effective schooling, also the primacy of the home in values formation, and the importance of home and school working together. The aim of this study is to investigate whether home-schooled children are able to identify and enact values they have learned as part of their education, if there is a values system that has been passed between parents and children, and if the values education of a home schooling family fulfils the requirements of the Australian Government. The methodology chosen to explore this phenomenon was a case study of the Davis family. It was found that values education situated within home schooling did not disadvantage children. The results showed that values, as an educational goal and outcome were a high priority, intentional and fulfilled the requirements of the Australian Government. Also, the study confirmed that values education had real life and significant impact on the children of the Davis family. This research will be valuable not only for bridging a gap in literature, but also in attempting to focus attention on the need to understand the phenomenon of home schooling from all aspects, including values education

    The emergence of Bitcoin in 2009 has received considerable attention surrounding the validity of cryptocurrencies as a viable and, in some jurisdictions, a legal currency alternative. Despite widespread concern that these cryptocurrencies are fostering the environment within which a substantial bubble can occur, it is important to analyze whether these new assets are behaving similarly to major international currencies. This paper investigates the effects of international monetary policy changes on bitcoin returns using a GARCH (1.1) estimation model. The results indicate that monetary policy decisions based on interest rates taken by the Federal Open Market Committee in the United States significantly impact upon bitcoin returns. After controlling for international effects, we find significant evidence of volatility effects driven by United States, European Union, United Kingdom and Japanese quantitative easing announcements. These results show that, despite its nature and ideals, bitcoin seems to be subject to the same economic factors as traditional fiat currencies, and is not entirely unaffected by government policies. This result has implications for investors using bitcoin as a hedging or diversification tool. In addition, we contribute to the existing debate regarding the classification of bitcoin as an asset class, by illustrating that bitcoin volatility exhibits various reactions that bear resemblance to both currency pairs and store-of-value assets

    AIM: To report 4 cases of Cryptococcus gattii (C. gattii) species complex infection with diverse ophthalmic manifestations, and to review the literature to examine pathobiology of disease, classical ophthalmic presentations and outcomes, and treatment modalities for this emerging pathogen. METHODS: Cases of C. gattii meningoencephalitis with ophthalmic manifestations were identified via chart review at two institutions in Australia and one institution in the mid-west region of the United States and are reported as a case series. Additionally, a MEDLINE literature review was conducted to identify all reported cases of C. gattii with ophthalmic manifestations from 1990-2020. Cases were reviewed and tabulated, together with our series of patients, in this report. RESULTS: Four cases of C. gattii with ophthalmic manifestations are presented; three from Australia and one from the USA. A literature review identified a total of 331 cases of C. gattii with visual sequelae. The majority of cases occurred in immunocompetent individuals. Blurred vision and diplopia were the most common presenting symptoms, with papilloedema the most common sign, reported in 10%-50% of cases. Visual loss was reported in 10%-53% of cases, as compared to rates of visual loss of 1%-9% in C. neoformans infection. Elevated intracranial pressure, cerebrospinal fluid (CSF) fungal burden, and abnormal neurological exam at presentation correlated with poor visual outcomes. The mainstays of treatment are anti-fungal agents and aggressive management of intracranial hypertension with serial lumbar punctures. CSF diversion procedures should be considered for refractory cases. Acetazolamide and mannitol are associated with high complication rates, and adjuvant corticosteroids have demonstrated higher mortality rates; these treatments should be avoided. CONCLUSION: Permanent visual loss represents a devastating yet potentially preventable sequelae of C. gattii infection. Intracranial hypertension needs to be recognised early and aggressively managed. Referral to an ophthalmologist/neuro-ophthalmologist in all cases of cryptococcal infection independent of visual symptoms at time of diagnosis is recommended

    "It is not possible to go inside and have a discussion": how fear of stigma affects delivery of community-based support for children's HIV care.

    Caregivers mediate children's access to HIV care and their adherence to treatment. Support for caregivers may improve health outcomes in children, but fear of HIV stigma and discrimination can affect both uptake and delivery of support services. Within a trial evaluating community-based support for caregivers of newly HIV diagnosed children in Harare, Zimbabwe, we conducted a longitudinal qualitative study to explore how stigma affected delivery and acceptance of the intervention. We conducted semi-structured interviews with 36 caregivers, 15 children, and 20 community health workers (CHWs). Children and caregivers described experiencing or witnessing stigma and discrimination, causing some to resist home visits by CHWs. Anxiety around stigma made it difficult for CHWs to promote key messages. In response, CHWs adapted the intervention by meeting caregivers outside the home, pretending to be friends or relatives, and proactively counteracting stigmatising beliefs. As members of local communities, some CHWs shared concerns about discrimination. HIV stigma can hinder "getting a foot over the threshold" in community-based programmes, particularly for households most affected by discrimination and thus least likely to engage with services. For community support programmes to be effective, stigma-related resistance should be addressed from the outset, including CHWs' own concerns regarding HIV stigma

    Adolescents' and caregivers' perceptions of caregiver-provided testing and HIV self-testing using oral mucosal transudate tests in Zimbabwe: a short report.

    Get PDF
    Uptake of HIV testing remains lower among children and adolescents compared to adults. This study explored adolescents' perceptions of HIV self-testing (HIVST) and caregivers' perceptions of testing their children using an oral mucosal transudate (OMT) rapid HIV test (caregiver-provided testing). We conducted 31 interviews with adolescents aged 16-18 years and caregivers of children aged 2-15 years who received an OMT test. Participants described barriers to HIV testing including lack of privacy and the potential for discrimination by community members towards children and adolescents who received an HIV test. Most participants felt caregiver-provided testing and HIVST could address these barriers through increased privacy. Some participants expressed worry about their ability to correctly perform the OMT and their anxious reactions to a positive result. Counseling and assistance from health care workers were viewed as ways to alleviate concerns. Concerns shaped participants' preferences for facility-based HIVST and caregiver-provided testing. Findings demonstrate HIVST performed by adolescents and caregiver-provided testing could increase the uptake of HIV testing. Concerns related to being able to test correctly and the availability of post-test counseling must be addressed in any future delivery mechanisms

    BACKGROUND: Substantial numbers of children with HIV present to health care services in older childhood and adolescence, previously undiagnosed. These "slow-progressors" may experience considerable chronic ill health, which is not well characterized. We investigated the prevalence of chronic morbidity among children aged 6-15 years at diagnosis of HIV infection. METHODS: A cross-sectional study was performed at 7 primary care clinics in Harare, Zimbabwe. Children aged 6-15 years who tested HIV positive following provider-initiated HIV testing and counseling were recruited. A detailed clinical history and standardized clinical examination was undertaken. The association between chronic disease and CD4 count was investigated using multivariate logistic regression. RESULTS: Of the 385 participants recruited [52% female, median age 11 years (interquartile range 8-13)], 95% were perinatally HIV infected. The median CD4 count was 375 (interquartile range 215-599) cells per cubic millimeter. Although 78% had previous contact with health care services, HIV testing had not been performed. There was a high burden of chronic morbidity: 23% were stunted, 21% had pubertal delay, 25% had chronic skin disease, 54% had a chronic cough of more than 1 month-duration, 28% had abnormal lung function, and 12% reported hearing impairment. There was no association between CD4 count of <500 cells per cubic millimeter or <350 cells per cubic millimeter with WHO stage or these chronic conditions. CONCLUSIONS: In children with slow-progressing HIV, there is a substantial burden of chronic morbidity even when CD4 count is relatively preserved. Timely HIV testing and prompt antiretroviral therapy initiation are urgently needed to prevent development of chronic complications

    OBJECTIVE: We previously proposed a simple tool consisting of five items to screen for risk of HIV infection in adolescents (10-19 years) in Zimbabwe. The objective of this study is to validate the performance of this screening tool in children aged 6-15 years attending primary healthcare facilities in Zimbabwe. METHODS: Children who had not been previously tested for HIV underwent testing with caregiver consent. The screening tool was modified to include four of the original five items to be appropriate for the younger age range, and was administered. A receiver operator characteristic analysis was conducted to determine a suitable cut-off score. The sensitivity, specificity and predictive value of the modified tool were assessed against the HIV test result. RESULTS: A total of 9568 children, median age 9 (interquartile, IQR: 7-11) years and 4971 (52%) men, underwent HIV testing. HIV prevalence was 4.7% (95% confidence interval, CI:4.2-5.1%) and increased from 1.4% among those scoring zero on the tool to 63.6% among those scoring four (P < 0.001). Using a score of not less than one as the cut-off for HIV testing, the tool had a sensitivity of 80.4% (95% CI:76.5-84.0%), specificity of 66.3% (95% CI:65.3-67.2%), positive predictive value of 10.4% and a negative predictive value of 98.6%. The number needed to screen to identify one child living with HIV would drop from 22 to 10 if this screening tool was used. CONCLUSION: The screening tool is a simple and sensitive method to identify children living with HIV in this setting. It can be used by lay healthcare workers and help prioritize limited resources
