How Tulsa, Oklahoma, Responds to Survivors of Domestic Violence: Results from an Assessment of Services and System Responses for Domestic Violence Survivors and Victims

The Urban Institute received funding from the George Kaiser Family Foundation to conduct a mixed-methods assessment of adult domestic violence (DV) in Tulsa, Oklahoma.1The purpose of Urban's study was to understand major programs, policies, services, and funding sources geared toward preventing and responding to adult DV survivors and recommend ways Tulsa could improve its response to domestic violence. The first part of the mixed-method assessment focused primarily on the largest service provider in Tulsa, Domestic Violence Intervention Services, Inc. (DVIS). The second part of the assessment focused on qualitative data collection with criminal legal and human services agencies and stakeholders to provide insight into the larger domestic violence landscape in Tulsa. Based on the assessment findings, we identified seven overarching recommendations – and examples of ways to implement each recommendation – for how Tulsa could improve its response to domestic violence. This report begins with recommendations and "how to" guidance on how responders in Tulsa can improve their response to DV to prevent violence, keep victims safe, and hold people who cause harm accountable. These recommendations are based directly on what we learned during our assessment. After this guidance, we provide the assessment findings that led to the recommendations

Nine Strategies to Guide Efforts to Reduce Youth Gun Violence

Gun violence, including that perpetrated by young people, is a pernicious problem for many communities, particularly those facing historically high levels of concentrated disadvantage and disinvestment. To effectively address youth gun violence and establish and maintain peace, communities need stable safety infrastructures and effective interventions.We developed a research-based practice guide to help local governments, law enforcement agencies, and antiviolence organizations determine how to shape their approaches to reducing gun violence perpetrated by young people ages 10 to 25 in gangs or groups. Here, we summarize the guide's recommendations on how to develop effective interventions and build a broader safety infrastructure that supports the success of different partners working to protect young people and communities from gun violence

A Research-Based Practice Guide to Reduce Youth Gun and Gang/Group Violence

While extensive research exists, the field lacks a current and translational synthesis of what works to reduce youth group and gun violence. In response, the Urban Institute developed a research-based practice guide to inform local government, law enforcement, and community-violence-intervention stakeholders as they implement new antiviolence interventions and refine existing ones. To inform the development of the guide, Urban researchers conducted a comprehensive literature synthesis of research on violence reduction interventions and conducted a scan of interventions representing well-known antiviolence models and other innovative strategies. Drawing on the findings from the literature synthesis and scan of practice, the practice guide presents recommendations around nine practice areas related to building an infrastructure to support a multi-faceted antiviolence strategy and implementing effective violence reduction programs

Nanofluidic Devices with Two Pores in Series for Resistive-Pulse Sensing of Single Virus Capsids

We report fabrication and characterization of nanochannel devices with two nanopores in series for resistive-pulse sensing of hepatitis B virus (HBV) capsids. The nanochannel and two pores are patterned by electron beam lithography between two microchannels and etched by reactive ion etching. The two nanopores are 50-nm wide, 50-nm deep, and 40-nm long and are spaced 2.0-μm apart. The nanochannel that brackets the two pores is 20x wider (1 μm) to reduce the electrical resistance adjacent to the two pores and to ensure the current returns to its baseline value between resistive-pulse events. Average pulse amplitudes differ by <2% between the two pores and demonstrate the fabrication technique is able to produce pores with nearly identical geometries. Because the two nanopores in series sense single particles at two discrete locations, particle properties, e.g., electrophoretic mobility, are determined from the pore-to-pore transit time
