This study is looking at how platelets-blood cells that help stop bleeding-are collected, processed, and used for cancer patients in Malawi. Right now, platelet supplies are limited, and some transfusions are delayed or not completed. We want to understand what happens at each step, from the blood donors who give blood, to the Malawi Blood Transfusion Service where platelets are prepared, to the hospitals where patients receive them. By reviewing donor and lab records, tracking transfusions, and talking with doctors, nurses, and lab staff, we hope to find simple, realistic ways to improve the process. The goal is to make platelet transfusions safer, faster, and more reliable for patients who need them most.

We want to better understand hearing (like speech perception or sound source localization) across the lifespan.

The Parenting After Loss Study looks at how grief, mental health, and parenting change over time for parents who have lost a spouse or co-parent. We hope to learn what helps parents and children adjust after loss and what kinds of support are most helpful. This follow-up study invites parents who previously took part in the Widowed Parent Study to complete a new survey and, for some, a one-time interview. The goal is to better understand families' long-term experiences and to help hospitals, counselors, and community programs provide stronger support for parents and children coping with grief. Note: Recruitment for this study is limited to prior participants of the Widowed Parent Study who consented to future contact.

Improve counseling around vaccine hesitancy for first year pediatric residents.

This study is needed because the Irish nationalist cause persists as long as Britain continues to occupy the six counties in the North of Ireland, known since partition in 1921 as 'Northern Ireland'. The sectarian division between Catholic nationalists and Protestant loyalists, and all the resulting political and social conflict, have continued in Northern Ireland despite the Good Friday Agreement, and so continued research and attention to societal challenges in the region is incredibly important to ensure the voices of Northern Irish are heard and considered in the ways we think about how sectarian divisions have evolved in recent decades. More specifically, this research will consider how Kneecap, who have emerged as a prominent cultural force only within the last few years, have changed the nature of Irish nationalism today by making the Irish language 'in vogue' and galvanizing support for decolonial movements both in Ireland and globally. Because of how

This study will examine how effective the use of a simulated model to teach ultrasound guided needle procedures for diagnosis and treatment in obstetrics, such as amniocentesis and fetal shunt placement.

We use an online conjoint experiment to study how diplomatic, military, and business elites formulate assessments of threat and opportunity in international politics.

This study looks at how local governments, community groups, and residents work together to clean up parks that were found to have contamination, such as lead or other pollutants. The goal is to understand what helps these groups cooperate, share information, and rebuild trust. By learning from people involved in these efforts, the study hopes to find better ways for communities and officials to communicate and make decisions about keeping parks safe and healthy for everyone.

We are collecting blood and optionally stool, bone marrow or tissue samples from patients who received cell therapy or a stem cell transplant to treat cancer. This will help understand how the immune system recovers after cell therapy or stem cell transplant and how it may relate to patient outcomes.

The purpose of the study is to evaluate the impact of the Minimizing Text Complexity guidelines and tools and resources to support their use to increase access to the general education curriculum for students with significant cognitive disabilities.
