‘Aboriginal mass culture’: a critical history

In Australia, some Aboriginal art objects are celebrated as fine art of great cultural, aesthetic and economic value, while the vast majority are judged to be stylistically derivative and intrinsically compromised by overtly mercenary market forces. This article introduces the concept ‘Aboriginal mass culture’ as a means for understanding the significance of the often maligned forms of the Aboriginal art and culture industry in Australia and to address the problem of why it continues to be difficult to demarcate the space of Aboriginal fine art. While a canonical and connoisseurial art history approach must disavow the vast majority of ‘Aboriginal art’, this article embraces a sociological perspective and turns an analytical eye upon the Aboriginal art and culture industry in its entirety, treating it as a phenomenon of visual culture that mediates Indigenous/non-indigenous relations within national public culture. It offers a critical history of ‘Aboriginal mass culture’ from the market for ‘Aboriginalia’ in the post-Second World War era through to the unruly Aboriginal art market of the present day. In so doing, it illuminates some of the drivers of these cultural forms across commercial, governmental and civil society domains. Its analysis reveals the way in which ‘Aboriginal mass culture’ manifests the unique social and economic circumstances that underpin Aboriginal art practices and the ways in which Aboriginal art is entangled with a redemptive political and civic project in Australia that has sought to affirm a resilient Indigenous presence and stimulate new visions of nationhood, heritage and intercultural fellowship.     

The Costs of Future Polio Risk Management Policies

Decisionmakers need information about the anticipated future costs of maintaining polio eradication as a function of the policy options under consideration. Given the large portfolio of options, we reviewed and synthesized the existing cost data relevant to current policies to provide context for future policies. We model the expected future costs of different strategies for continued vaccination, surveillance, and other costs that require significant potential resource commitments. We estimate the costs of different potential policy portfolios for low-, middle-, and high-income countries to demonstrate the variability in these costs. We estimate that a global transition from routine immunization with oral poliovirus vaccine (OPV) to inactivated poliovirus vaccine (IPV) would increase the costs of managing polio globally, although routine IPV use remains less costly than routine OPV use with supplemental immunization activities. The costs of surveillance and a stockpile, while small compared to routine vaccination costs, represent important expenditures to ensure adequate response to potential outbreaks. The uncertainty and sensitivity analyses highlight important uncertainty in the aggregated costs and demonstrates that the discount rate and uncertainty in price and administration cost of IPV drives the expected incremental cost of routine IPV vs. OPV immunization.     

Development and Consideration of Global Policies for Managing the Future Risks of Poliovirus Outbreaks: Insights and Lessons Learned Through Modeling

The success of the Global Polio Eradication Initiative promises to bring large benefits, including sustained improvements in quality of life (i.e., cases of paralytic disease and deaths avoided) and costs saved from cessation of vaccination. Obtaining and maintaining these benefits requires that policymakers manage the transition from the current massive use of oral poliovirus vaccine (OPV) to a world without OPV and free of the risks of potential future reintroductions of live polioviruses. This article describes the analytical journey that began in 2001 with a retrospective case study on polio risk management and led to development of dynamic integrated risk, economic, and decision analysis tools to inform global policies for managing the risks of polio. This analytical journey has provided several key insights and lessons learned that will be useful to future analysts involved in similar complex decision-making processes.     

Portfolio assessment in a collaborative program evaluation: the reliability and validity of a family literacy portfolio

Evaluations increasingly use open-ended assessments, such as portfolios, to gather information about program impact. Portfolios, however, present challenges in achieving acceptable levels of reliability and often lack evidence to support validity. This article describes the components of a portfolio assessment system developed in a collaborative evaluation of a family literacy program. Staff of a family literacy program and two evaluators collaborated to develop the assessment and the tools that frame the review of the portfolios. Rubrics, exemplar portfolios, portfolio logs, and lists of ‘look-fors’ were developed to guide raters in the scoring and to improve the reliability of scores and validity of decisions about the program. Inter-rater reliability for the portfolio assessment was 0.79 for holistic scores and 0.74 for analytic scores. With respect to validity, holistic and analytic scores correlated with criterion measures from 0.50 to 0.59, providing initial evidence of a common construct.     

Validating Benefit and Cost Estimates: The Case of Airbag Regulation

Preregulation estimates of benefits and costs are rarely validated after regulations are implemented. This article performs such a validation for the mandatory automobile airbag requirement. We found that the original 1984 model used to estimate benefits became invalid when 1997 values were input into that 1984 model. However, using a published 1997 cost-effectiveness model, we demonstrate, by replacing the model inputs with the values from 1984, that the 1997 cost-effectiveness ratios, based on real-world crash data and tear-down cost data, are less attractive than what would have been originally anticipated. The three most important errors in the 1984 input values are identified: the overestimation of airbag effectiveness, the overestimation of baseline fatality/injury rates, and the underestimation of manual safety belt use. This case study, which suggests that airbags are a reasonable investment in safety, shows that the regulatory analysis tools do not always produce findings that are biased against health, safety, and environmental regulation. Future validation studies of health, safety, and environmental regulation should focus on validation of benefit and risk estimates, areas where we found significant error, as well as on cost estimates.     

Managing human resource shortages in a unionized setting: Best practices in air traffic control

Human resource shortages require effective human resource management (HRM). Findings from research about ongoing labor shortages in air traffic control (ATC) are used to build a preliminary theory of appropriate HRM responses. Our international sample of major ATC agencies generally developed a set of best HRM practices to attract, motivate, and retain human assets. Key factors included (1) cultural and institutional norms, (2) technological change, (3) union responses, and (4) organizational form and structure (e.g., civil service versus commercial firms). While ATC’s rare human aptitudes, lengthy training to develop firm-specific human capital, and lifelong employment may limit the preliminary theory’s general applicability, crucial lessons emerge about human resource planning. This research was conducted with the support of the Social Sciences and Humanities Research Council, the Rice Fellowship, the Ziegler Fellowship, and the Center for International Business Studies at the University of Alberta. We are indebted to the individuals interviewed.     

Evaluation of Proactive and Reactive Strategies for Polio Eradication Activities in Pakistan and Afghanistan

Only Pakistan and Afghanistan reported any polio cases caused by serotype 1 wild polioviruses (WPV1s) in 2017. With the dwindling cases in both countries and pressure to finish eradication with the least possible resources, a danger exists of inappropriate prioritization of efforts between the two countries and insufficient investment in the two countries to finish the job. We used an existing differential‐equation‐based poliovirus transmission and oral poliovirus (OPV) evolution model to simulate a proactive strategy to stop transmission, and different hypothetical reactive strategies that adapt the quality of supplemental immunization activities (SIAs) in response to observed polio cases in Pakistan and Afghanistan. To account for the delay in perception and adaptation, we related the coverage of the SIAs in high‐risk, undervaccinated subpopulations to the perceived (i.e., smoothed) polio incidence. Continuation of the current frequency and quality of SIAs remains insufficient to eradicate WPV1 in Pakistan and Afghanistan. Proactive strategies that significantly improve and sustain SIA quality lead to WPV1 eradication and the prevention of circulating vaccine‐derived poliovirus (cVDPV) outbreaks. Reactive vaccination efforts that adapt moderately quickly and independently to changes in polio incidence in each country may succeed in WPV1 interruption after several cycles of outbreaks, or may interrupt WPV1 transmission in one country but subsequently import WPV1 from the other country or enable the emergence of cVDPV outbreaks. Reactive vaccination efforts that adapt independently and either more rapidly or more slowly to changes in polio incidence in each country may similarly fail to interrupt WPV1 transmission and result in oscillations of the incidence. Reactive strategies that divert resources to the country of highest priority may lead to alternating large outbreaks. Achieving WPV1 eradication and subsequent successful OPV cessation in Pakistan and Afghanistan requires proactive and sustained efforts to improve vaccination intensity in under‐vaccinated subpopulations while maintaining high population immunity elsewhere.     

Family support: A review of the literature on families of adolescents with disabilities

ABSTRACT

For all youth, adolescence is a time of great change, marked by multiple transitions. For those with disabilities, these transitions can be especially challenging for the youth and their families. Although families of adolescents with disabilities often require support, it is unclear what types of assistance are most helpful. To understand the responsibilities of and, correspondingly, supports needed for parents and siblings, the authors conducted a comprehensive literature review. Specifically, the authors examined the literature to identify the supports that families provide to their adolescent relatives with disabilities, the impacts of caring for an adolescent relative with a disability, and the assistance that families receive. The authors conclude by discussing implications for future research about family support.
