The ABC of Child Care Politics

The care and education of children below school age is an area of intense public debate and the subject of considerable policy innovation in Western democracies. Child care raises complex philosophical and policy issues ranging from broad questions about the relative responsibilities of state, market and family to technical aspects of policy design such as the interaction of child care subsidies with income support, family payments and taxation. Across the developed world, countries are finding new ways to address the growing need for child care, with market‐based solutions looming large in several countries. This paper analyses Commonwealth policy towards long day care in Australia since the early 1990s. It explores the shift towards market‐based, for‐profit care for children below school age, especially the growth of publicly listed child care corporations. In allowing a single corporation to assume a dominant position in the provision of long day care, Australia has embarked on a vast experiment in the care of children, unparalleled in other countries.     

The power of the fisher permutation test in 2 × k tables

The power of the Fisher permutation test extended to 2 × k tables is evaluated unconditionally as a function of the under-lying cell probabilities in the table. These results are then applied in assessing the sensitivity of two-generation cancer bioassays in which a fixed number of pups from each litter born in the first generation are selected to continue on test in the second generation. In this case, the two rows of the table correspond to two treatment groups and the k columns correspond to the number of animals responding in a litter. The cell probabilities in this application are based on a suitable beta-binomial superpopulation model.     

Return of the Nanny: Public Policy towards In‐home Childcare in the UK,Canada and Australia

Research on early childhood education and care (ECEC) policy focuses overwhelmingly on formal, centre‐based provision and, to a lesser extent, on family day care (or childminding) provided in the homes of registered carers. Comparatively little research addresses the policy treatment of care provided in the child's home by nannies and au pairs. This article examines the position of in‐home childcare in Australia, the UK and Canada, and the varied nature and extent of public funding and regulation. Introducing a new dimension into comparative studies of ECEC, it also explores how shifts in migration policy in each country have intersected with ECEC funding and regulation to reshape the recruitment and employment of in‐home child carers. Australia, the UK and Canada are all liberal, market‐oriented countries, but there is considerable diversity in the way governments support and regulate in‐home childcare, their rationales for so doing, and in the connections between childcare and migration. We argue that connecting the analysis of in‐home childcare to migration policies raises new questions about the classification and comparison of ECEC policies.     

Making projects, making friends: online community as catalyst for interactive media creation

To become full and active participants in today's technologically saturated society, young people need to become creators (and not just consumers) of interactive media. Developing the requisite abilities and capacities is not a wholly individual process; it is important for young people to have access to communities where they can collaborate and share ideas. This article uses the Scratch online community for exploring how different forms of participation and collaboration can support and shape the ways in which young people develop as creators of interactive media. We describe participation in this community in terms of a spectrum ranging from socializing to creating and present examples of three forms of collaboration within the community. We argue that the most exciting interactive media creation and valuable learning experiences are taking place in the middle space, where participants draw on the best of socializing and creating practices.     

Performance analysis of a multi-agent scheduling and control system under manufacturing disturbances

This paper is concerned with evaluating the performance of alternative multi-agent approaches to manufacturing planning and control. In order to separate the influence of ‘control algorithm’ from that of ‘control architecture’, a simple local control algorithm is chosen as a common starting point for developing the agent-based system. Two sets of experiments are then reported to evaluate how changes in individual agent characteristics can affect the control system's flexibility and adaptability against disturbances. These experiments show that the manufacturing and control system performance is not affected by architecture if the control algorithm remains fixed, however, altering the characteristics of the control system decision-makers influences both systems’ performance.     

Flat rate taxes and relative poverty measurement

We provide a systematic analysis of the impact of revenue-neutral changes to the parameters of a flat rate tax system on the level of relative poverty (where the poverty line is some fraction of either the mean or the median post-tax income level). We also perform a similar analysis for a negative income tax system. We find that the choice of poverty line type has important consequences in respect of how changes to the tax parameters affect the level of relative poverty. Our results are illustrated with a numerical simulation, in which we allow the pre-tax income distribution to be either given exogenously or determined endogenously.     

Negotiating independence,choice and autonomy: experiences of parents who coordinate personal assistance on behalf of their adult son or daughter

Article 19 of the UN Convention on the Rights of Persons with Disabilities requires states to provide personal assistance services. This article is based on qualitative research in Iceland, Norway and Sweden, carried out between 2012 and 2013. The overall study focused broadly on the implementation of Article 19. This article, however, reports findings based on a particular group of participants within the larger study: non-disabled parents who coordinate personal assistance schemes for their adult son or daughter. The article examines the various ways in which the parents, the majority of whom were mothers, negotiate principles of independence, choice and autonomy for their adult son or daughter who requires intensive support, including assistance with communicating. The aim is to explore, in the context of the Convention and the principles of the independent living movement, how to acknowledge and conceptualise personal assistance schemes that require another person to manage on behalf of the user.     

The LGBQ Microaggressions on Campus Scale: A Scale Development and Validation Study

Although LGBQ students experience blatant forms of heterosexism on college campuses, subtle manifestations such as sexual orientation microaggressions are more common. Similar to overt heterosexism, sexual orientation microaggressions may threaten LGBQ students’ academic development and psychological wellbeing. Limited research exists in this area, in part due to lack of a psychometrically sound instrument measuring the prevalence of LGBQ microaggressions on college campuses. To address this gap, we created and tested the LGBQ Microaggressions on College Campuses Scale. Two correlated subscales were generated: Interpersonal LGBQ Microaggressions and Environmental LGBQ Microaggressions. The results indicated that the subscales demonstrate strong reliability and validity.     

Using short-term evidence to predict six-month outcomes in clinical trials of signs and symptoms in rheumatoid arthritis

A model is presented to generate a distribution for the probability of an ACR response at six months for a new treatment for rheumatoid arthritis given evidence from a one- or three-month clinical trial. The model is based on published evidence from 11 randomized controlled trials on existing treatments. A hierarchical logistic regression model is used to find the relationship between the proportion of patients achieving ACR20 and ACR50 at one and three months and the proportion at six months. The model is assessed by Bayesian predictive P-values that demonstrate that the model fits the data well. The model can be used to predict the number of patients with an ACR response for proposed six-month clinical trials given data from clinical trials of one or three months duration.
