Nurse Leader Perspectives on Precepting in a Graduate Nursing Administration Practicum.
J Nurs Adm
December 2024
Author Affiliations: Assistant Professor (Dr Hickman), Assistant Professor (Dr Petri), and Coordinator (Connors), University of Maryland School of Nursing, Baltimore.
Objective: To describe practicum experiences as perceived by nurse leader preceptors of graduate students in a nursing administration practicum.
Background: Practicum experiences in graduate nursing administration programs provide students with exposure to the real-life experiences of nurse leaders, bridging the gap between academic knowledge gained and the application of that information to the workplace. The literature lacks best practices for graduate nursing administration practicum experiences.
A hybrid unsupervised machine learning model with spectral clustering and semi-supervised support vector machine for credit risk assessment.

In credit risk assessment, unsupervised classification techniques can be introduced to reduce human resource expenses and expedite decision-making. Despite the efficacy of unsupervised learning methods in handling unlabeled datasets, their performance remains limited owing to challenges such as imbalanced data, local optima, and parameter adjustment complexities. Thus, this paper introduces a novel hybrid unsupervised classification method, named the two-stage hybrid system with spectral clustering and semi-supervised support vector machine (TSC-SVM), which effectively addresses the unsupervised imbalance problem in credit risk assessment by targeting global optimal solutions.

Detecting directional couplings from time series is crucial in understanding complex dynamical systems. Various approaches based on reconstructed state-spaces have been developed for this purpose, including a cross-distance vector measure, which we introduced in our recent work. Here, we devise two new cross-vector measures that utilize ranks and time series estimates instead of distances.

Mikrochim Acta

Department of Chemistry and Material Engineering, Lyuliang University, Lyuliang, 033000, P. R. China.
Innovative double-emission carbon dots (DE-CDs) were synthesized via a one-step hydrothermal method using fennel and m-phenylenediamine (m-PD) as precursors. These DE-CDs exhibited dual emission wavelengths at 432 and 515 nm under different excitations, making them highly versatile for fluorescence-based applications. The fluorescence of the DE-CDs was efficiently quenched by tetracycline (TC) through the inner filter effect (IFE), allowing for the construction of a sensitive dual-response fluorescent sensor.

Background: While the significance of care navigation in facilitating access to health care within the lesbian, gay, bisexual, transgender, queer, and other (LGBTQ+) communities has been acknowledged, there is limited research examining how care navigation influences an individual's ability to understand and access the care they need in real-world settings. By analyzing private sector data, we can bridge the gap between theoretical research findings and practical applications, ultimately informing both business strategies and public policy with evidence grounded in real-world efficacy.
Objective: The objective of this study was to evaluate the impact of specialized virtual care navigation services on LGBTQ+ individuals' ability to comprehend and access necessary care within a national cohort of commercially insured members.
