Nursing students' perception of class size and its impact on test performance: a pilot study.

The combination of increasing student enrollment in baccalaureate nursing programs and the faculty shortage has contributed to larger class sizes that may affect both student satisfaction and learning. The purpose of this study was to identify baccalaureate nursing students' satisfaction with enrollment in small and large nursing courses. The authors also sought to determine whether a significant difference existed between test scores of students enrolled in small and large nursing courses. A survey was completed by 110 students, and test scores were compared between students in a small and a large nursing class using analysis of variance. The findings indicated that perceived satisfaction of students was significantly higher for those enrolled in the small nursing course versus the large course; however, no significant difference was found between test scores. To improve student satisfaction that can positively affect student retention, further research is needed on class size in the nursing discipline.

Impostor Phenomenon in Undergraduate Nursing Students: A Pilot Study of Prevalence and Patterns.

BACKGROUND: Impostor phenomenon (IP) is an experience of doubt in personal ability and a sense that achievements are fraudulent, resulting in increased psychological distress. This pilot study explored the prevalence and pattern of IP in baccalaureate nursing students related to gender, level in program, and racial identity. METHOD: A convenience sample of prelicensure baccalaureate nursing students (n = 150) was surveyed using the Clance Impostor Phenomenon Scale (CIPS). RESULTS: The mean CIPS score was 60.13 (range, 26-92). Patterns observed across gender, level in program, or racial identity did not differ significantly. However, frequent to intense feelings of impostorism were reported by 48.7% of students, and 92% reported at least moderate IP characteristics. CONCLUSION: Many students in this study reported IP experiences, indicating risk for negative effects such as anxiety and lack of confidence. Further study in this population and specifically among minority nursing students is needed. [J Nurs Educ. 2021;60(6):329-332.].

Disruption of a ∼23-24 nucleotide small RNA pathway elevates DNA damage responses in Tetrahymena thermophila.

Endogenous RNA interference (RNAi) pathways regulate a wide range of cellular processes in diverse eukaryotes, yet in the ciliated eukaryote, Tetrahymena thermophila, the cellular purpose of RNAi pathways that generate ∼23-24 nucleotide (nt) small (s)RNAs has remained unknown. Here, we investigated the phenotypic and gene expression impacts on vegetatively growing cells when genes involved in ∼23-24 nt sRNA biogenesis are disrupted. We observed slower proliferation and increased expression of genes involved in DNA metabolism and chromosome organization and maintenance in sRNA biogenesis mutants RSP1Δ, RDN2Δ, and RDF2Δ. In addition, RSP1Δ and RDN2Δ cells frequently exhibited enlarged chromatin extrusion bodies, which are nonnuclear, DNA-containing structures that may be akin to mammalian micronuclei. Expression of homologous recombination factor Rad51 was specifically elevated in RSP1Δ and RDN2Δ strains, with Rad51 and double-stranded DNA break marker γ-H2A.X localized to discrete macronuclear foci. In addition, an increase in Rad51 and γ-H2A.X foci was also found in knockouts of TWI8, a macronucleus-localized PIWI protein. Together, our findings suggest that an evolutionarily conserved role for RNAi pathways in maintaining genome integrity may be extended even to the early branching eukaryotic lineage that gave rise to Tetrahymena thermophila.
