Rational Higher-Order Belief Revision in Young Children

Belief revision can occur at multiple levels of abstraction, including lower-level and higher-order beliefs. It remains unclear, however, how conflicting evidence interacts with prior beliefs to encourage higher-order belief revision. This study explores how 4- and 5-year-olds (N = 96) respond to evidence that directly conflicts with their causal higher-order beliefs. When shown a single event that directly violated a strongly supported prior belief, preschoolers largely maintained their initial higher-order belief. However, when the prior belief was more weakly supported and the counterevidence was stronger, children changed their minds. These findings indicate that young children can revise their higher-order beliefs and, furthermore, do so depending on the strength of both the evidence and their prior beliefs.     

Droplet dispensing in digital microfluidic devices: Assessment of long-term reproducibility

We report an in-depth study of the long-term reproducibility and reliability of droplet dispensing in digital microfluidic devices (DMF). This involved dispensing droplets from a reservoir, measuring the volume of both the droplet and the reservoir droplet and then returning the daughter droplet to the original reservoir. The repetition of this process over the course of several hundred iterations offers, for the first time, a long-term view of droplet dispensing in DMF devices. Results indicate that the ratio between the spacer thickness and the electrode size influences the reliability of droplet dispensing. In addition, when the separation between the plates is large, the volume of the reservoir greatly affects the reproducibility in the volume of the dispensed droplets, creating "reliability regimes." We conclude that droplet dispensing exhibits superior reliability as inter-plate device spacing is decreased, and the daughter droplet volume is most consistent when the reservoir volume matches that of the reservoir electrode.     

Developmental Trends in Sexual Attraction Among Puerto Rican Early Adolescents in Two Contexts

Sexual attraction (SA), the earliest stage of sexual orientation, is scarcely studied. This prospective study examined, over 3 years, prevalence, changes in SA, and the role of context, among 946 Puerto Rican youth, aged 11–13 years at initial assessment in the South Bronx (SBx), New York City, and Puerto Rico (PR). Overall, 98.1% of boys and 95.3% of girls reported opposite-sex only SA at some point, whereas 13.8% of girls and 12.0% of boys reported any-same SA. Opposite-sex only SA increased over time, whereas other SAs decreased except for any same-sex SA among SBx girls. Girls in the SBx and younger youth in PR reported more any same-sex SA. Context and culture may play a role in the developmental trajectories of adolescents’ SA.     

Time to end the bias towards inclusive education?

The UK coalition Government's call to end the ‘bias’ towards inclusion represents a shift in ‘policy speak’ as the new administration attempts to re‐narrate special education by putting forward a ‘reasonable and sensible’ solution to the ‘problem of inclusion’. However, implicit in the call is the assumption that there has, in fact, been a ‘bias towards inclusion’ in education policy and practice; here, that assumption is challenged. Using a critical disability studies perspective, Katherine Runswick‐Cole, who is a research fellow in Disability Studies and Psychology in the Research Institute of Health and Social Change at Manchester Metropolitan University, draws on the concept of ableism and critiques of neo‐liberal market systems in education to reveal and explore the persistent barriers to inclusive education embedded within the education system. It is argued that although there may have been an inclusive education policy rhetoric, this rhetoric is rooted in conceptual incongruities which, rather than promoting inclusion, undermine an inclusive approach to education.     

A case for a collaborative classroom

Collaboration is an important skill. But what do we do when students just can't (or won't) work together effectively? Dorothy A. Osterholt and Katherine Barratt share their structured, supportive approach.     

Publisher–Society partnerships to further image accessibility and global inclusivity in the Humanities and Social Sciences: Comparing top-down and bottom-up approaches

• Collaboration between publishers and learned society partners can accelerate and amplify DEIA outcomes.
• 97 HSS titles have adopted alt-text publication workflows and this change has been welcomed by journal authors and editors.
• Efforts to promote global inclusivity do not always result in greater membership diversity, retention and growth.
• Top-down, publisher-led DEIA initiatives are effective when they are aligned strategically to pre-existing society initiatives.
• Bottom-up, member-led DEIA initiatives benefit from publisher support to mitigate financial and time-based barriers to active participation.
• To reliably track DEIA outcomes, publishers ought to adopt systematic data collection strategies through initiatives like C4 and the Joint Commitment.
