Resident Experiences With a Place-Based Collaboration to Address Health and Social Inequities: A Survey of Visitors to the East Harlem Neighborhood Health Action Center.

In 2016 and 2017, the New York City Department of Health and Mental Hygiene established Neighborhood Health Action Centers (Action Centers) in disinvested communities of color as part of a place-based model to advance health equity. This model includes co-located partners, a referral and linkage system, and community space and programming. In 2018, we surveyed visitors to the East Harlem Action Center to provide a more comprehensive understanding of visitors' experiences. The survey was administered in English, Spanish, and Mandarin. Respondents were racially diverse and predominantly residents of East Harlem. The majority had been to the East Harlem Action Center previously. Most agreed that the main service provider for their visit made them feel comfortable, treated them with respect, spoke in a way that was easy to understand, and that they received the highest quality of service. A little more than half of returning visitors reported engaging with more than one Action Center program in the last 6 months. Twenty-one percent of respondents reported receiving at least one referral at the Action Center. Two thirds were aware that the Action Center offered a number of programs and services and half were aware that referrals were available. Additional visits to the Action Center were associated with increased likelihood of engaging with more than one program and awareness of the availability of programs and referral services. Findings suggest that most visitors surveyed had positive experiences, and more can be done to promote the Action Center and the variety of services it offers.

The Neighborhood as a Unit of Change for Health: Early Findings from the East Harlem Neighborhood Health Action Center.

Place-based approaches have been promoted as one way to reduce health inequities by addressing community-level factors that shape health, such as housing quality, healthcare systems, the built environment, and social capital. In 2016-2017, the NYC Health Department's Center for Health Equity launched three Neighborhood Health Action Centers (Action Centers), which use a place-based approach to improve health in neighborhoods with disproportionate burdens of premature mortality. We describe this approach and the genesis of the Action Centers. We then describe the East Harlem Action Center, which was the first to open, and share findings from qualitative interviews with the East Harlem Action Center's Governance Council, a group comprised of Action Center staff and co-located partners and programs which supports Action Center coordination. Interviewees felt that collaboration, being responsive to community needs, and being community based were essential elements of the Action Center. Interviewees recognized the complex dynamic of a large city agency serving as the host for the Action Center while simultaneously aiming to establish more equitable relationships with partners. Governance Council members' expectations and hopes for the East Harlem Action Center were consistent with the overall vision and model for the Action Centers, which may facilitate implementation.

Dynamics of quadrupedal locomotion of monkeys: implications for central control.

We characterized the three-dimensional kinematics and dynamics of quadrupedal gait of young adult rhesus and cynomolgus monkeys while they walked with diagonal and lateral gaits at 0.4-1.0 m/s on a treadmill. Rigid bodies on the wrist, ankle, and back were monitored by an optical motion detection system (Optotrak). Kinematic data could be normalized using characteristic stride length, reducing variance due to different gait styles, to emphasize common characteristics of swing and stance parameters among animals. Mean swing phase durations fell as walking speed increased, but the swing phase durations increased at each walking velocity as a linear function of increases in amplitude, thereby following a main sequence relationship. The phase plane trajectories of the swing phases, i.e., plots of the relation of the rising and falling limb velocity to limb position in the sagittal (X-Z) plane, had unique dynamic characteristics. Trajectories were separable at each walking velocity and increases in swing amplitude were linearly related to peak swing velocities, thus comprising main sequences. We infer that the swing phase dynamics are set by central neural mechanisms at the onset of the swing phases according to the intended amplitude, which in turn is based on the walking velocity in the stance phases. From the many dynamic similarities between swing phases and rapid eye movements, we further suggest that the swing phases may be generated by neural mechanisms similar to those that produce saccades and quick phases of nystagmus from a signal related to sensed or desired walking velocity.

The nodulus and uvula: source of cerebellar control of spatial orientation of the angular vestibulo-ocular reflex.

The nodulus and rostral-ventral uvula of the vestibulo-cerebellum play a critical role in orienting eye velocity of the slow component of the angular vestibulo-ocular reflex (aVOR) to gravito-inertial acceleration (GIA). This is done by altering the time constants of "velocity storage" in the vestibular system and by generating "cross-coupled" eye velocities that shift the eye velocity vector from along the body yaw axis to the yaw axis in a spatial frame. In this report, we show that eye velocity generated through the aVOR by constant velocity centrifugation in the monkey orients to the GIA in space, regardless of the position of the head with respect to the axis of rotation. We also show that, after removal of the nodulus and rostral-ventral uvula, the spatial orientation of eye velocity to the GIA is lost and that eye velocity is then purely driven by the semicircular canals in a body frame of reference. These findings are further confirmation that these regions of the vestibulo-cerebellum control spatial orientation of the aVOR.
