This mixed-methods analysis uses exit surveys from 17 teacher education programs in four US states to compare self-ratings of preparedness between two cohorts of preservice teachers: 2019 graduates ...who had “normal” student teaching experiences (n = 1264) and 2020 graduates (n = 1280), for whom in-person student teaching was shortened by 6–10 weeks during the spring 2020 COVID-19 school closures. Despite truncated student teaching experiences, the 2020 cohort felt more prepared. Through a theoretical lens of self-efficacy, we explore how these differences might reflect a generative process as future teachers deepen their understanding of complexities in teaching, and grapple to bridge theory and practice.
•Preservice teachers with shorter student teaching experiences rated themselves as more prepared.•Preservice teachers with less student teaching attributed their preparation to vicarious and social persuasion experiences.•Student teaching helps preservice teachers align self-estimations derived from coursework with realities of classroom management.
We have performed angle-resolved photoemission spectroscopy on Tl_0.5_Bi_2_Te_3_ (TBT), a possible topological superconductor (TSC) derived from prototypical topological insulator Bi_2_Te_3_. We ...found that Fermi surface consists of multiple three-dimensional hole pockets surrounding the Z point, unlike another well-known topological-superconductor candidate Cu_x_Bi_2_Se_3. We also found that surface state can be controlled by surface-aging technique, making TBT an excellent platform to realize 2D TSC.
Rodents are important reservoirs of many human pathogens transmitted via arthropod vectors. Arthropod-borne bacteria belonging to the family Rickettsiaceae cause acute febrile diseases in humans ...worldwide, but the real burdens of rickettsial diseases appear to be underestimated in Hanoi, Vietnam, because differential diagnosis on the basis of clinical signs and symptoms is confounded by the presence of other tropical infectious diseases with similar signs and symptoms. To know the prevalence of bacteria of the family Rickettsiaceae among small mammals in Hanoi, 519 animals thriving in the public places were captured and examined for the presence of bacterial sequences using duplex PCR. Nucleotide sequences specific for Orientia tsutsugamushi were detected in seven samples (1.3%). Out of seven animals, two were captured in a market, whereas five were in hospitals. None of the captured small mammals tested positive for the genus Rickettsia. The nucleotide sequence analysis of the genes encoding the 47-kDa high-temperature requirement A (47-kDa HtrA) and 56-kDa type-specific antigen (TSA) showed that these seven isolates were indistinguishable from each other. O. tsutsugamushi isolated in this study was closely related phylogenetically to the Gilliam strain, which was originally isolated at the border of Assam and Burma, rather than to those isolated in the central to southern part of Vietnam. It should be emphasized that Vietnamese hospitals were heavily infested by small rodents and some of them harbored O. tsutsugamushi. Strict hygienic control should be implemented to mitigate the potential risk posed by O. tsutsugamushi in hospital settings.
