There are multiple devices that have been developed and approved to help treat heart failure symptoms, yet some patients who qualify for these devices are denied authorization by their insurance. We look to describe trends across the United States.

As machine learning is accepted as one of the most powerful tools to solve problems that involve a large amount of data, more and more application areas started to explore and adopt machine learning methods into their workflows. The first step of developing a machine learning model is to determine the target variable, i.e. what to predict. For instance, if a practitioner wants to develop a model to assist hiring decisions, he/she may choose a candidate's performance score as the prediction target to train the machine learning model. In practice, practitioners need to experiment and evaluate a large set of potential target variables until they reach a satisfactory one. We would like to automate the evaluation of target variables and recommend good ones to the users. The purpose of this study is to understand how different recommendation strategies influence the target selection process.

The purpose of this research study is to improve the understanding and satisfaction with confidential reporting of learning environment concerns for Pediatric Resident physicians. We will conduct a baseline needs assessment survey , followed by targeted education on a singular reporting system, covering report submission, procedural follow-up, and outcome communication. A follow-up survey will evaluate for change in the understanding of and satisfaction with the process. Through this intervention, the objective is to enhance clarity and satisfaction with the reporting process.

The purpose of the study is to analyze if asking questions on polarizing topics reduces response quality The study will analyze the research question using an experiment. Respondents will be randomly assigned to one of two main conditions. The experimental group will receive uncomfortable or embarrassing true-or-false questions about their political party, depending on what party they identify with. The questions are factual but may be perceived as biased or polarizing. The control group will receive 3 true-or-false questions about Democrats and 3 true-or-false questions about Republicans. Later, the researcher will compare instances/rates of satisficing, affective polarization, sentiment codes, internal consistency, conformity, and truthfulness between the experimental and control groups.

This study aims to understand implementation of Restorative Practices in selected NC public elementary schools, the reason for implementation failures and successes in selected schools, and the underlying causes of such failures and successes.

The purpose of this study is to evaluate patient-reported improvement in design and comfort with SONNET 3 (EAS) over the existing AP models available, and to measure patient-reported impressions of usability and satisfaction with the SONNET 3 (EAS) AP.

We are studying the relationships between migraine and postpartum mood for the first three months after childbirth. We are interested in how women are able to cope with their migraine symptoms during the postpartum (after childbirth), and whether this affects their mood. We know that migraine and postpartum mood can be worse in women who have lower income and who identify with a minoritized racial or ethnic group. We are exploring why.

The goal of this study is to assess the feasibility of a nutrition program for individuals with cancer who are undergoing treatment. The nutrition program includes counseling from a registered dietitian, food logging, and nutrition symptom tracking.

The purpose of this study is to learn about students' experiences using AI tools in their programming classes. We want to understand how these tools help with learning, what challenges students face, and their overall opinions about using AI for their coursework. By talking directly with students, we hope to discover ways to make AI tools more useful for learning and improve how they are used in education.

We are launching a national Fracture Prevention Program that aims to improve your bone health and reduce the risk of a future broken bone.
