Battling the coronavirus 'infodemic' among social media users in Kenya and Nigeria.

How can we induce social media users to be discerning when sharing information during a pandemic? An experiment on Facebook Messenger with users from Kenya (n = 7,498) and Nigeria (n = 7,794) tested interventions designed to decrease intentions to share COVID-19 misinformation without decreasing intentions to share factual posts. The initial stage of the study incorporated: (1) a factorial design with 40 intervention combinations; and (2) a contextual adaptive design, increasing the probability of assignment to treatments that worked better for previous subjects with similar characteristics. The second stage evaluated the best-performing treatments and a targeted treatment assignment policy estimated from the data.

Emotion may predict susceptibility to fake news but emotion regulation does not seem to help.

Misinformation is a serious concern for societies across the globe. To design effective interventions to combat the belief in and spread of misinformation, we must understand which psychological processes influence susceptibility to misinformation. This paper tests the widely assumed - but largely untested - claim that emotionally provocative headlines are associated with worse ability to identify true versus false headlines.

"If we move, it moves with us:" Physical distancing in Africa during COVID-19.

Health behaviors to prevent the spread of infectious diseases are often subject to collective action problems, and social norms can play an important role in inducing compliance. In this paper, we study knowledge, beliefs, and behavior related to one such practice during the COVID-19 pandemic - physical distancing - using an online survey of social media users in Kenya, Nigeria, and Uganda. We find that, while there is widespread knowledge that physical distancing reduces the spread of the virus, respondents underestimate their peers' support for policies designed to enforce physical distancing, expect others to practice physical distancing, and do not maintain physical distance themselves.

Ethical Reflections on Offering Patients Accelerated Resolution Therapy (ART).

Accelerated resolution therapy (ART) is a new therapy for post-traumatic stress disorder (PTSD) that has shown exceptional promise. Compared with other standard, more evidence-based treatments, initial research has shown ART to be as effective, quicker, easier to learn, and more cost-efficient. There are ethical issues clinicians should consider before recommending ART to their patients, including the need for additional research to fully establish ART's net benefits and the difficulty patients might encounter accessing therapists trained to perform ART-based therapy.

Anatomical and biomechanical framework for shoulder arthroplasty rehabilitation.

This article provides an anatomical and biomechanical framework for the postoperative management and progression of treatment for shoulder arthroplasty. The clinical relevance of normal shoulder anatomy, biomechanics, and pathomechanics related to this surgery is emphasized to provide the reader with an understanding of the rationale for treatment. We review the rehabilitation implications of surgical indications and technique for both traditional total shoulder arthroplasty and reverse total shoulder arthroplasty procedures with an emphasis on biomechanical considerations.
