A global experiment on motivating social distancing during the COVID-19 pandemic
Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges
A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.
The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world
To the Tables Down at Mory\u27s : Equality as Membership and Leadership in Places of Public Accommodations
The Mory\u27s Club is emblematic of all that is old Yale. The walls are lined with framed black and white photos of clean-cut athletes and the tables have been etched by singing groups that made the club legendary in verse. The memories enshrined at Mory\u27s, however, reveal the social barriers to gender integration. When a group of Yale graduates incorporated the Mory\u27s Association in September 1912 with the purpose of promot[ing] ... social intercourse and the culture of its members, gender discrimination was not a legal claim but rather a part of daily life. Half a century later, Yale College opened its doors to female students, and members of the Yale community urged Mory\u27s to do the same. In the local movement that ultimately forced Mory\u27s to admit women, civic participation reshaped women\u27s equality in elite institutions and pushed the boundaries of law, or at minimum, expanded its shadow

Don't Panic: Making Progress on the "Going Dark" Debate
Just over a year ago, with support from the William and Flora Hewlett Foundation, the Berkman Center for Internet & Society at Harvard University convened a diverse group of security and policy experts from academia, civil society, and the U.S. intelligence community to begin to work through some of the particularly vexing and enduring problems of surveillance and cybersecurity.
The group came together understanding that there has been no shortage of debate. Our goals were to foster a straightforward, non-talking-point exchange among people who do not normally have a chance to engage with each other and then to contribute in meaningful and concrete ways to the discourse on these issues.
A public debate unfolded alongside our meetings: the claims and questions around the government finding a landscape that is “going dark” due to new forms of encryption introduced into mainstream consumer products and services by the companies who offer them. We have sought to distill our conversations and some conclusions in this report. The participants in our group who have signed on to the report, as listed on the following page, endorse “the general viewpoints and judgments reached by the group, though not necessarily every finding and recommendation.” In addition to endorsing the report, some signatories elected to individually write brief statements, which appear in Appendix A of the report and also as individual posts on Lawfareblog.com, written by Jonathan Zittrain, Bruce Schneier, and Susan Landau.
Our participants who are currently employed full-time by government agencies are precluded from signing on because of their employment, and nothing can or should be inferred about their views from the contents of the report. We simply thank them for contributing to the group discussions
Large-scale transcriptomic analysis reveals that pridopidine reverses aberrant gene expression and activates neuroprotective pathways in the YAC128 HD mouse
Background:
Huntington Disease (HD) is an incurable autosomal dominant neurodegenerative disorder driven by an expansion repeat giving rise to the mutant huntingtin protein (mHtt), which is known to disrupt a multitude of transcriptional pathways. Pridopidine, a small molecule in development for treatment of HD, has been shown to improve motor symptoms in HD patients. In HD animal models, pridopidine exerts neuroprotective effects and improves behavioral and motor functions. Pridopidine binds primarily to the sigma-1 receptor, (IC50 ~ 100 nM), which mediates its neuroprotective properties, such as rescue of spine density and aberrant calcium signaling in HD neuronal cultures. Pridopidine enhances brain-derived neurotrophic factor (BDNF) secretion, which is blocked by putative sigma-1 receptor antagonist NE-100, and was shown to upregulate transcription of genes in the BDNF, glucocorticoid receptor (GR), and dopamine D1 receptor (D1R) pathways in the rat striatum. The impact of different doses of pridopidine on gene expression and transcript splicing in HD across relevant brain regions was explored, utilizing the YAC128 HD mouse model, which carries the entire human mHtt gene containing 128 CAG repeats.
Methods:
RNAseq was analyzed from striatum, cortex, and hippocampus of wild-type and YAC128 mice treated with vehicle, 10 mg/kg or 30 mg/kg pridopidine from the presymptomatic stage (1.5 months of age) until 11.5 months of age in which mice exhibit progressive disease phenotypes.
Results:
The most pronounced transcriptional effect of pridopidine at both doses was observed in the striatum with minimal effects in other regions. In addition, for the first time pridopidine was found to have a dose-dependent impact on alternative exon and junction usage, a regulatory mechanism known to be impaired in HD. In the striatum of YAC128 HD mice, pridopidine treatment initiation prior to symptomatic manifestation rescues the impaired expression of the BDNF, GR, D1R and cAMP pathways.
Conclusions:
Pridopidine has broad effects on restoring transcriptomic disturbances in the striatum, particularly involving synaptic transmission and activating neuroprotective pathways that are disturbed in HD. Benefits of treatment initiation at early disease stages track with trends observed in the clinic.Other UBCNon UBCReviewedFacult
