Bibliometric analysis of post-traumatic growth after childbirth.

AIM: To make a bibliometric analysis on post-traumatic growth (PTG) after childbirth. METHODS: The topic advanced search strategy extracted the information from the Web of Science Core Collection. Descriptive statistics were performed using Excel, and bibliometric analysis was performed using VOSviewer. RESULTS: A total of 362 publications were published in 199 journals were obtained in the WoSCC from 1999 to 2022. Postpartum post-traumatic growth is in a trend of fluctuating growth, and the United States (N = 156) and Bar-Ilan University (N = 22) were the top contributing countries and institutions, respectively. Research hotspots mainly focus on theoretical models of PTG, postpartum post-traumatic stress disorder (PTSD) as a predictor of PTG, facilitators of PTG, and the relationship between mother-infant attachment and PTG. CONCLUSION: This bibliometric study provides a comprehensive overview of the current state of research on PTG after childbirth, an area that has received considerable scholarly attention in recent years. However, research on post-traumatic growth after childbirth is lacking, and further research is needed.

Toward a less costly but accurate calculation of the CCSD(T)/CBS noncovalent interaction energy.

The popular method of calculating the noncovalent interaction energies at the coupled-cluster single-, double-, and perturbative triple-excitations [CCSD(T)] theory level in the complete basis set (CBS) limit was to add a CCSD(T) correction term to the CBS second-order Møller-Plesset perturbation theory (MP2). The CCSD(T) correction term is the difference between the CCSD(T) and MP2 interaction energies evaluated in a medium basis set. However, the CCSD(T) calculations with the medium basis sets are still very expensive for systems with more than 30 atoms. Comparatively, the domain-based local pair natural orbital coupled-cluster method [DLPNO-CCSD(T)] can be applied to large systems with over 1,000 atoms. Considering both the computational accuracy and efficiency, in this work, we propose a new scheme to calculate the CCSD(T)/CBS interaction energies. In this scheme, the MP2/CBS term keeps intact and the CCSD(T) correction term is replaced by a DLPNO-CCSD(T) correction term which is the difference between the DLPNO-CCSD(T) and DLPNO-MP2 interaction energies evaluated in a medium basis set. The interaction energies of the noncovalent systems in the S22, HSG, HBC6, NBC10, and S66 databases were recalculated employing this new scheme. The consistent and tight settings of the truncation parameters for DLPNO-CCSD(T) and DLPNO-MP2 in this noncanonical CCSD(T)/CBS calculations lead to the maximum absolute deviation and root-mean-square deviation from the canonical CCSD(T)/CBS interaction energies of less than or equal to 0.28 kcal/mol and 0.09 kcal/mol, respectively. The high accuracy and low cost of this new computational scheme make it an excellent candidate for the study of large noncovalent systems.

The satisfaction of the undergraduate nursing classroom teaching quality based on the Kano model in China.

Objectives: To investigate the satisfaction of the undergraduate nursing classroom teaching quality based on the Kano model and provide a reference for improving the overall quality of educational services. Methods: A total of 621 sophomores and juniors of nursing at Hubei University of Medicine were selected to conduct questionnaires based on the Kano model using convenient sampling. Results: The 16 items are all a one-dimensional factor. The satisfaction and importance are 0.77 to 0.86 and -0.58 to -0.80, respectively. In the quadrant analysis chart, there are four items in the dominant area, three items for improvement, three in the observation area, and six in the retention area. Conclusion: Analyzing the satisfaction of nursing undergraduates' classroom teaching quality can help us effectively understand the intrinsic needs of students and improve the overall quality of nursing undergraduates' curriculum teaching services.
