What Will You Protect? Redefining Professionalism Through the Lens of Diverse Personal Identities.

Introduction: Professional identity formation (PIF) encapsulates the process of incorporating a physician's professional identity into existing personal identity. Medical schools shape PIF by reinforcing professional norms defined by a historical physician phenotype. Increasingly, medical students who are underrepresented in medicine must confront the apparent contradictions between personal identities and the often-subjective definitions of professionalism endorsed by faculty, patients, and peers.

Ethical and Regulatory Considerations for Using Social Media Platforms to Locate and Track Research Participants.

As social media becomes increasingly popular, human subjects researchers are able to use these platforms to locate, track, and communicate with study participants, thereby increasing participant retention and the generalizability and validity of research. The use of social media; however, raises novel ethical and regulatory issues that have received limited attention in the literature and federal regulations. We review research ethics and regulations and outline the implications for maintaining participant privacy, respecting participant autonomy, and promoting researcher transparency when using social media to locate and track participants.

A retinal code for motion along the gravitational and body axes.

Self-motion triggers complementary visual and vestibular reflexes supporting image-stabilization and balance. Translation through space produces one global pattern of retinal image motion (optic flow), rotation another. We examined the direction preferences of direction-sensitive ganglion cells (DSGCs) in flattened mouse retinas in vitro.
