Bootstrap tests for multivariate directional alternatives

Tests on multivariate means that are hypothesized to be in a specified direction have received attention from both theoretical and applied points of view. One of the most common procedures used to test this cone alternative is the likelihood ratio test (LRT) assuming a multivariate normal model for the data. However, the resulting test for an ordered alternative is biased in that the only usable critical values are bounds on the null distribution. The present paper provides empirical evidence that bootstrapping the null distribution of the likelihood ratio statistic results in a bootstrap test (BT) with comparable power properties without the additional burden of assuming multivariate normality. Additionally, the tests based on the LRT statistic can reject the null hypothesis in favor of the alternative even though the true means are far from the alternative region. The BT also has similar properties for normal and nonnormal data. This anomalous behavior is due to the formulation of the null hypothesis and a possible remedy is to reformulate the null to be the complement of the alternative hypothesis. We discuss properties of a BT for the modified set of hypotheses (MBT) based on a simulation study. The resulting test is conservative in general and in some specific cases has power estimates comparable to those for existing methods. The BT has higher sensitivity but relatively lower specificity, whereas the MBT has higher specificity but relatively lower sensitivity.     

“Where’s the human dignity in that?”: LGBTQIA + people with intellectual disability exploring sexual lives and respectful relationships

Abstract

For people with disabilities, sexuality remains a contested and restricted space. This research investigated how the Sexual Lives & Respectful Relationships (SL&RR) program might be adapted for people with intellectual disabilities who identify as LGBTQIA+. The program included co-developed materials and specifically curated narratives. It was received positively. The facilitators identifying as members of the LGBTQIA+ community was also reported as positive. While an inclusive program might be ideal, participants expressed the view that community attitudes (including those of other people with intellectual disability) might not yet be conducive to integrated human relationships programs.     

Happiness Research: A Review of Critiques

In the short decades since the introduction of positive psychology instigated broader interdisciplinary research, interest in happiness has been growing in academia, the media and public policy. Numerous critiques of these developments have been forwarded from a variety of theoretical and disciplinary traditions. This article discusses three such criticisms: the culture‐bound and normative character of happiness, ‘bad science’ and scientism, and diminished subjectivity and individualisation. It is argued that criticism, particularly internal criticism, evidences the maturity of the field. However, the depth of some critiques may also indicate that interest in happiness is bound with broader cultural preoccupations and is likely to be superseded.
