On the robustness of weighted methods for fitting models to case–control data

Summary. We compare the robustness under model misspecification of two approaches to fitting logistic regression models with unmatched case–control data. One is the standard survey approach based on weighted versions of population estimating equations. The other is the likelihood-based approach that is standard in medical applications. The conventional view is that the (less efficient) survey-weighted approach leads to greater robustness. We conclude that this view is not always justified.     

A Systematic Review of Emergent Learning Outcomes Produced by Foreign language Tact Training

This systematic review evaluated the effects of foreign tact training on emergent learning outcomes in ten published studies. We also conducted a meta-analysis of aggregate data from seven studies comparing outcomes of foreign tact training with other verbal operant procedures. The preliminary findings indicated foreign tact training produced criterion-level responses in 84 of 106 (79.2%) post-test probes across 37 learners and 55 evaluations of foreign tact training. The meta-analysis results revealed significantly higher within-subjects mean levels of emergent responding following foreign tact training than foreign-to-native intraverbal, native-to-foreign intraverbal, and foreign listener training. Emergent outcomes for adults were not significantly greater than for children. Finally, foreign tact training was slightly more efficient than the other verbal operant procedures, although most of the differences were not statistically significant.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40616-022-00170-z.

Doing Things Differently: Can Water Supply,Sanitation, and Hygiene Services Support Peace‐ and State‐Building Processes?

Interventions across all sectors in fragile states are called to contribute to tackling conflict and fragility despite the lack of evidence on how/if this is possible. This article reviews the existing literature to identify five entry points through which water supply and sanitation service delivery might interact, both positively and negatively, with state‐building and/or peace‐building processes. Evidence for the relevance of these entry points was assessed in the Republic of South Sudan and the Democratic Republic of Congo. Our research suggests that the way in which water and sanitation services are delivered is more important than the delivery of these services per se. Moreover, we find that the effects are largely modest and likely to be localised, and that greater attention is still needed to avoid potential negative consequences.     

A statistical uncertainty principle for estimating the time of a discrete shift in the mean of a continuous time random process

The purpose of this article is to present a statistical uncertainty principle that can be used when localizing a single change in the mean of a band-limited stationary random process. The statistical model investigated is a continuous time process that experiences a shift in its mean. This continuous time process is presumed to be sampled using an ideal low-pass filter. The least squares estimate of the location of the change in mean is asymptotically Gaussian. The standard deviation of the least squares estimate of the location of the change-point provides a physical limit to the accuracy of the estimate of the time of the mean shift which cannot be bettered.     

The work of disabled identities in intimate relationships

This article details a thematic analysis of disabled men and women’s accounts of past and present intimate relationships. Drawing upon the sexual stories of 25 disabled people, informants’ intimate relationships are explored as a site of emotional work, and as a site of other forms of (gendered) work. This article critically questions the work carried out by informants and considers the ways in which it was shaped by their lived experiences of gender, sexuality, impairment and disability. The article concludes that the requirement to carry out forms of work within intimate and sexual life constituted a form of psycho-emotional disablism.
