Becoming rhizomatic parents: Deleuze, Guattari and disabled babies

In order for the sociological study of disability to enable, then it must be ready to conceptualize complex terrains of knowledge and activism. Research has to work alongside disabled people, their allies, their practices, their resistances and their theorizing. This paper makes a case for a framework of understanding that situates such work. Disability studies tends to understand its concepts (e.g. disability, exclusion, inclusion, impairment, politicization, people) as entities rooted in arborescent and hierarchical forms of knowledge. These modernist misconceptions can be challenged through understanding knowledge, practice, living and activism as rhizomatic, captured as lines of flight which are always becoming. As a new reader of Deleuze and Guattari, I make a case for disability research understanding parents and their disabled children as deconstructing or (re)deterritorializing the areas of policy, politics, practice, theory and activism. Creating burrows for shelter and eventual breakout, becoming 'angel makers', drawing on narratives of parents of disabled babies, this paper maps out a vision of parents not blocked by the strata of disabling society, but enabled by lines of flight, resistance, flux and change. This paper aims to be Deleuzoguattarian but only in ways that fit the complexities of parents' accounts.     

Bootstrap Estimation of Benchmark Doses and Confidence Limits with Clustered Quantal Data

The benchmark dose (BMD) is an exposure level that would induce a small risk increase (BMR level) above the background. The BMD approach to deriving a reference dose for risk assessment of noncancer effects is advantageous in that the estimate of BMD is not restricted to experimental doses and utilizes most available dose-response information. To quantify statistical uncertainty of a BMD estimate, we often calculate and report its lower confidence limit (i.e., BMDL), and may even consider it as a more conservative alternative to BMD itself. Computation of BMDL may involve normal confidence limits to BMD in conjunction with the delta method. Therefore, factors, such as small sample size and nonlinearity in model parameters, can affect the performance of the delta method BMDL, and alternative methods are useful. In this article, we propose a bootstrap method to estimate BMDL utilizing a scheme that consists of a resampling of residuals after model fitting and a one-step formula for parameter estimation. We illustrate the method with clustered binary data from developmental toxicity experiments. Our analysis shows that with moderately elevated dose-response data, the distribution of BMD estimator tends to be left-skewed and bootstrap BMDL s are smaller than the delta method BMDL s on average, hence quantifying risk more conservatively. Statistically, the bootstrap BMDL quantifies the uncertainty of the true BMD more honestly than the delta method BMDL as its coverage probability is closer to the nominal level than that of delta method BMDL. We find that BMD and BMDL estimates are generally insensitive to model choices provided that the models fit the data comparably well near the region of BMD. Our analysis also suggests that, in the presence of a significant and moderately strong dose-response relationship, the developmental toxicity experiments under the standard protocol support dose-response assessment at 5% BMR for BMD and 95% confidence level for BMDL.
