ObjectivesWe describe health-related quality of life during the COVID-19 pandemic in the general Dutch population and correlations with restrictive measures.MethodsData were obtained from 18–85 year-old participants of two population-based cohort studies (February 2021-July 2022): PIENTER Corona (n = 8,019) and VASCO (n = 45,413). Per cohort, mean scores of mental and physical health and health utility from the SF-12 were calculated by age group, sex and presence of a medical risk condition. Spearman correlations with stringency of measures were calculated.ResultsBoth cohorts showed comparable results. Participants <30 years had lowest health utility and mental health score, and highest physical health score. Health utility and mental health score increased with age (up to 79 years), while physical health score decreased with age. Women and participants with a medical risk condition scored lower than their counterparts. Fluctuations were small over time but most pronounced among participants <60 years, and correlated weakly, but mostly positively with measure stringency.ConclusionsDuring the Dutch COVID-19 epidemic, health utility and mental health scores were lower and fluctuated strongest among young adults compared to older adults. In our study population, age, sex and presence of a medical risk condition seemed to have more impact on health scores than stringency of COVID-19 non-pharmaceutical interventions.

Introduction
Comprehensive abortion care is an emerging intervention being integrated into nursing and midwifery curricula. Yet, no studies have been conducted in Rwanda to determine whether faculty perceive themselves as capable of teaching comprehensive abortion care. This study aims to evaluate the perceived self-efficacy to teach comprehensive abortion care among nursing and midwifery faculty in higher learning institutions in Rwanda.

Materials and methods
The University of Rwanda College of Medicine and Health Sciences Institutional Review Board approved this study (UR-CMHS-IRB No 335/CMHSIRB/2022). In quantitative, a self-administered questionnaire was administered to 98 study participants. Data were entered into Statistical Package for the Social Sciences (SPSS) version 26 and analyzed using Chi-square test with a p-value of 0.05 set as the significance level. In the qualitative part, an interview guide was developed based on quantitative data to understand comprehensive abortion care teaching fully. Data were collected from four focus group discussions with eight participants in each group, entered in Dedoose, and analyzed thematically.

Results
Among the 98 study participants who were invited to participate in this study, only 85 filled out the questionnaires. This translates into 86.7% of the response rate. More than half 58.8% had adequate self-efficacy in teaching comprehensive abortion care. A Chi-square test has revealed that being a male, being a midwife, and having more years of working experience in nursing education were significantly associated with self-efficacy in teaching comprehensive abortion care (p value <0.05). In the qualitative phase, 32 study participants participated in four focus group discussions and four themes were identified: a) variability in confidence levels to teach comprehensive abortion care; b) readiness about teaching comprehensive abortion care; c) facilitators of teaching comprehensive abortion care; and d) contextual challenges to teach comprehensive abortion care.

Conclusions
The findings revealed that faculty’s self-efficacy in teaching comprehensive abortion care was not adequate. Personal and religious beliefs and institutional barriers were also reported to hinder self-efficacy in teaching comprehensive abortion care. Therefore, intensive comprehensive abortion care training for nursing and midwifery faculty in higher learning institutions should be provided, including values clarification and attitude transformation training for attitudes and beliefs. It is also critical for higher learning institutions to develop strategies for overcoming the challenges faculty face when teaching comprehensive abortion care.

„Hexenjagd im Bayern-Staat“: Die Universitätsbibliothek der LMU München und die Holzer-Affäre 1974
Authors: Kuttner Sven 
Published: March 2024

Zusammenfassung
Im Sommer 1974 stand die Universitätsbibliothek der LMU München unter einem gravierenden Zensurverdacht: Ihr wurde vorgeworfen, Werke des Soziologen und DKP-Mitglieds Horst Holzer der Benutzung absichtlich entzogen zu haben. Der Vorfall löste ein gewaltiges Presseecho in Westdeutschland aus, schien er doch alle Klischees eines repressiven CSU-Staates in Bayern zu bestätigen. Auch eine vom Verein Deutscher Bibliothekare eingesetzte Arbeitsgruppe „Behinderung der Informationsfreiheit bzw. von Informationszugang“ beschäftigte sich mit den inkriminierten Vorwürfen. Der Essay rekonstruiert anhand von archivalischem Quellenmaterial die Affäre und kontextualisiert sie mit den Studentenunruhen an der LMU.
Nutraceutical potential of Mesembryanthemum forsskaolii Hochst. ex Bioss.: Insights into its nutritional composition, phytochemical contents, and antioxidant activity

Published: March 2024

Abstract

Mesembryanthemum forsskaolii Hochst. ex Bioss is a resilient succulent plant in the Aizoaceae family. This plant has been recognized for its nutritional and metabolic benefits, but its potential remains underexplored. The aim of this research is to analyze the nutritional composition, phytochemical content, and antioxidant potential of M. forsskaolii. The protein content, total sugars, macro-, and micronutrients were estimated in seeds, leaves, and stems of the studied plant. To investigate the phytochemical profiles and antioxidant capacity, GC-MS analysis, determination of total phenolic, flavonoid, and tannin contents, ferric reducing antioxidant power (FRAP) and total antioxidant activity (TAC) tests, and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assays were conducted. The soluble protein (147.55 mg g−1 DW), total protein (341.23 mg g−1 DW), total carbohydrate (0.258 mg mL−1), and nitrogen (26.152 mg g−1) contents of M. forsskaolii seeds were the highest. Phytochemical analysis revealed the presence of several compounds, such as β-sitosterol, phthalic acid, and phytol, which have potential antioxidative, anti-inflammatory, and antimicrobial properties. Seeds showed the greatest presence of phenols, flavonoids, and tannins, indicating high antioxidant activity in FRAP and TAC tests. The ABTS and DPPH scavenging assays showed that the antioxidant activity increased proportionally with concentration in all plant parts. However, seeds consistently demonstrated the greatest capacity. This study provides a detailed analysis on the dietary protein, carbohydrates, essential nutrients, and antioxidants that can be obtained from M. forsskaolii, highlighting its potential as a valuable source of nutrition and phytochemicals.

Abstract
The current study aimed to examine the structural relationships between pre-service science teachers’ intention to teach and perceptions of the nature of science (NOS) and attitudes toward teaching science. The sample consisted of 206 pre-service science teachers from a major university in the United Arab Emirates who have bachelor’s degrees in science. Quantitative research methodology was used to study the structural relationships among pre-service science teachers’ intention to teach, perceptions of the NOS, and attitudes. Structural equation modeling using the Lavaan package was used to test these structural relationships. The results show that the relationships between the indigenous constructs (NOS) and the mediator constructs (DAS) can predict pre-service science teachers’ intention to teach science (p < 0.05).
Element geochemical differences in lower Cambrian black shales with hydrothermal sedimentation in the Yangtze block, South China

Abstract
Hydrothermal activities occurred in the Yangtze block, South China, and affected the process of black shale sedimentation in the early Cambrian. Their specific influences, such as the sources, sedimentary environment, and mineralization, have not yet been revealed. Fortunately, the influences are explained through the geochemistry comparison of different wells FY1, XJ1, HY1, and XA1 in northwestern Hunan. The outcomes of the tectonic setting, distinguishable by element indicators, are disorganized. This is caused by the variable element composition, sedimentary recirculation of material source, and hydrothermal materials. FY1, the closest well to Zhangjiajie where Ni–Mo ores were formed by hydrothermal sedimentation, has more different features on the elemental geochemistry, but many indexes still indicate that it is normal sediments. XA1, which is far from the other wells and deposited in the deep-water basin, has significantly more differences in geochemical properties and shows more about normal marine deposition. XJ1 and HY1 are intermediate between them. Based on these wells, the hydrothermal contribution to the black shale sedimentation is not significant. However, some contents of trace and rare earth elements change widely because hydrothermal materials can diffuse and deposit over long distances. The concentration of Ag, As, Ba, Mo, Ba, U, and V generally has dozens of times higher than that of Upper Continental Crust. The early Cambrian environment was primarily anoxic/euxinic with enough sulfur, which is beneficial for enriching metal elements and organic matter. The sequence FY1, XJ1, HY1, and XA1 in turn has the same performance on the distance with Zhangjiajie, different intervals of suboxic environment and element enrichment, and hydrothermal-fluid-addition Ni abundance. Therefore, hydrothermal processes indeed provide materials for element enrichment and support the reducing environment, but the impact of hydrothermal activity decreases on the plane.
