Study purpose was to evaluate how select college experiences affect cognitive outcomes among racial/ethnic populations of first-generation students. A nationwide dataset consisting of the 2006 The ...Freshman Survey (TFS) and the 2010 College Senior Survey (CSS) was utilized to address the research question. Findings from this study suggest that select college experiences positively affect cognitive outcomes, but the magnitudes of these effects vary for racial/ethnic subpopulations.

In this work we present an integrated set of tools allowing a multi-step process that, starting from raw datasets, brings them through dimensionality reduction, preclustering analysis and clustering ...assessment, to a visual and interactive environment for data exploration. At the core of the process lies the idea of subdividing the process of data clusterization into different steps: a preliminary analysis in which algorithmic parameters are estimated, a clustering step based on the previous analysis and, finally, a clusterization assessment step including interactive clustering. This last step allows users to participate in the process of clustering and helps them figuring out the data underlying structures. The models are actually implemented in a group of integrated, user-friendly tools under the MATLAB environment, featuring a number of classical and novel data processing, visualization, assessment and interaction methods.
Background: During the COVID-19 pandemic, emergency remote teaching (ERT) was implemented in the U.S., and some of the most vulnerable college students struggled to adapt. Purpose: The current study ...sought to understand the experiences and outcomes of undergraduate students enrolled in radiography programs while participating in synchronous online lectures during ERT, especially first-generation students. Specifically, this study focused on students who participated in class lectures that were taught online in a live and synchronous format due to COVID-19 stay-at-home orders. Methods: This study utilized a retrospective and longitudinal design where participants were asked to answer a series of questions retrospectively at two points in time with each question forming a pair. Survey participants were enrolled as students during ERT in 2020 through 2021 and participated in class lectures that were taught online in a live and synchronous format due to COVID-19 stay-at-home orders. Results: Wilcoxon Signed-Rank and Spearman Rank-Order tests suggest that ERT has affected the experiences and outcomes of students enrolled in radiography programs, with more pronounced negative effects for first-generation students. Conclusion and Recommendations: The researchers recommend yearly and preventative planning across three academic and administrative areas to include training, support, and technology as essential strategies for delivering remote education, specifically online synchronous lectures, in the context of ERT situations. Strategies in these three areas will keep the academic success of the most vulnerable and underserved college student populations at the forefront during emergency remote teaching scenarios.
A 21-year-old white woman, born with a univentricular heart, had undergone staged procedures before Fontan correction. She then began to develop edema, protein-losing enteropathy, and ascites ...refractory to diuretic therapy. Cardiac angiography showed a patent right Blalock-Taussig shunt, with turbulent cavopulmonary circulation. After undergoing an unsuccessful attempt at coil embolization she then underwent shunt ligation, with resolution of symptoms and normalization of protein levels. This report draws attention to the importance of cavopulmonary laminar flow to prevent the development of protein-losing enteropathy.
