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.

To evaluate the effect of mitapivat on albumin creatinine ratio (ACR) response in subjects with sickle cell disease (SCD) and nephropathy

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 asks participants about their pre-pandemic, current, and expected post-pandemic behaviors to better understand long-term societal changes that may occur as a result of the pandemic. The study focuses on transportation-related outcomes.

For more information, please visit our website: https://cecs.unc.edu The purpose of this research study is to learn more about the diagnosis, treatment, and survivorship experiences of adults with endometrial cancer. Initial enrollment goals are for 1,800 adults living in North Carolina at the time of their recent first diagnosis of endometrial cancer. This project will provide important data for integrating tumor biology, access to care, and other factors to identify contributors, and potential areas for intervention to address endometrial cancer disparities. Study staff will pursue annual follow-ups with participants, requesting updates to treatment status and quality of life measures for approximately 5yrs.

To assess the nature of ideological intuitions citizens use when making informed guesses about other people's political issue positions. In other words, what do people conclude about each other's wider system of political beliefs upon learning that a conversation partner supports (or opposes) a certain policy position or regulation (e.g. support for renewable energy investments, opposition to the death penalty). Intuitions about wider sets of political beliefs may be relevant to political decision making (e.g. voting, candidate appraisal) and in everyday social interactions (deciding which friend-circles to enter, whom to associate with, which clubs, associations to join, ect). The goal of this study is to gain an overview of the prevalence and relative strength of ideological intuitions for a set of 16 different political attitudes and identity markers.
