Research Mentoring and Scientist Identity: Insights from Undergraduates and their Mentors
Background Mentored research apprenticeships are a common feature of academic outreach programs that aim to promote diversity in science fields. The current study tests for links between three forms of mentoring (instrumental, socioemotional, and negative) and the degree to which undergraduates psychologically identify with science. Participants were 66 undergraduate-mentor dyads who worked together in a research apprenticeship. The undergraduate sample was predominantly composed of women, first-generation college students, and members of ethnic groups that are historically underrepresented in science. Results Findings illustrated that undergraduates who reported receiving more instrumental and socioemotional mentoring were higher in scientist identity. Further, mentors who reported engaging in higher levels of negative mentoring had undergraduates with lower scientist identity. Qualitative data from undergraduates’ mentors provided deeper insight into their motivation to become mentors and how they reason about conflict in their mentoring relationships. Conclusions Discussion highlights theoretical implications and details several methodological recommendations
Solar slow magneto-acoustic-gravity waves: an erratum correction and a revisited scenario
Slow waves are commonly observed on the entire solar atmosphere. Assuming a
thin flux tube approximation, the cut-off periods of slow-mode
magneto-acoustic-gravity waves that travel from the photosphere to the corona
were obtained in Costa et al. (2018). In that paper, however, a typo in the
specific heat coefficient at constant pressure value led to an
inconsistency in the cut-off calculation, which is only significant at the
transition region. Due to the abrupt temperature change in the region, a change
of the mean atomic weight (by a factor of approximately two) also occurs, but
is often overlooked in analytical models for simplicity purposes. In this
paper, we revisit the calculation of the cut-off periods of
magneto-acoustic-gravity waves in Costa et al. (2018) by considering an
atmosphere in hydrostatic equilibrium with a temperature profile, with the
inclusion of the variation of the mean atomic weight and the correction of the
inconsistency aforementioned. In addition, we show that the cut-off periods
obtained analytically are consistent with the corresponding periods measured in
observations of a particular active region.Comment: 12 pages, 7 figures. MNRA
