Timely, Relevant, Practical: A Study of Writing Center Summer Institute Alumni Perceptions of Value and Benefits
Since its inception in 2003, the IWCA Summer Institute (SI) has been understood within the writing center field to be an important professional development opportunity for new and experienced writing center professionals (WCPs). Publications on the SI to date have focused on anecdotal perceptions of the benefits to leaders and participants or on a single outcome, such as research output. Thus, the writing center field knows little about how and in what ways participants perceive the SI’s benefits across cohorts and across a variety of professional areas. By gathering quantitative and qualitative data from every SI cohort from 2003 to 2019, the goal of this study was to identify and define the benefits of the SI, focusing in particular on how participants themselves understand them. The survey received 161 responses, a response rate of approximately 27%; all 17 years of the SI were represented. The study found that, despite the field’s shifting priorities since 2003, the concerns and needs of WCPs have remained relatively constant over time, and that the SI serves the most pressing administrative needs of participants
Does she think she’s supported? Maternal perceptions of their experiences in the neonatal intensive care unit
Parents’ involvement in the care of their infants in the neonatal intensive care unit (NICU) is critically important, leading many NICUs to implement policies and practices of family-centered care (FCC). Analyzing narrative interviews, we examined whether mothers of premature infants who participated in an intervention to help reduce anxiety, stress, and depression felt that their NICU experience reflected four key nursing behaviors previously identified as being necessary to achieving FCC. Fifty-six narratives derived from semi-structured interviews with the mothers were analyzed qualitatively and quantitatively to examine whether the women experienced emotional support, parent empowerment, welcoming environment, and parent education, as well as whether differences in reported experiences were related to sociodemographic factors or maternal coping styles. Overall, the mothers reported more negative than positive experiences with respect to the four behaviors, and those who had negative interactions with the hospital staff felt a sense of disenfranchisement and failure as mothers. Sociodemographic factors and coping styles were significantly associated with the mothers’ perceptions of their experiences, although these relationships were not consistent. Achieving actual FCC in the NICU may require parent-informed evidence-based changes in NICU personnel training and infrastructure

The massive double-lined O-type binary HD 165052
We present a new optical spectroscopic study of the O-type binary HD 165052 based on high-and intermediate-resolution CCD observations. We re-investigated the spectral classification of the binary components, obtaining spectral types of O6.5 V and O7.5 V for the primary and secondary, respectively, finding that both stars display weak CIII λ5696 emission in their spectra. We also determined a radial-velocity orbit for HD 165052 with a period of 2.95510 ± 0.00001 d, and semi-amplitudes of 94.8 and 104.7 ± 0.5km s-1, resulting in a mass ratio Q = 0.9. From a comparison with previous radial-velocity determinations, we found evidence of apsidal motion in the system. Several signatures of wind-wind collision, such as phase-locked variability of the X-ray flux and the Struve-Sahade effect, are also considered. It was also found that the reddening in the region should be normal, in contrast with previous determinations.Facultad de Ciencias AstronĂłmicas y GeofĂsica

The periodicity of the η Carinae events
Extensive spectral observations of η Carinae over the last cycle, and particularly around the 2003.5 low-excitation event, have been obtained. The variability of both narrow and broad lines, when combined with data taken from two earlier cycles, reveal a common and well-defined period. We have combined the cycle lengths derived from the many lines in the optical spectrum with those from broad-band X-rays, optical and near-infrared observations, and obtained a period length of Ppres = 2022.7 ± 1.3 d.
Spectroscopic data collected during the last 60 yr yield an average period of Pavg = 2020 ± 4 d, consistent with the present-day period. The period cannot have changed by more than ΔP/P = 0.0007 since 1948. This confirms the previous claims of a true, stable periodicity, and gives strong support to the binary scenario. We have used the disappearance of the narrow component of He I 6678 to define the epoch of the Cycle 11 minimum, T0 = JD 245 2819.8. The next event is predicted to occur on 2009 January 11 (±2 d). The dates for the start of the minimum in other spectral features and broad-bands are very close to this date, and have well-determined time-delays from the He I epoch.Facultad de Ciencias AstronĂłmicas y GeofĂsica

How and with whom do educators learn in an online professional development microcredential
A claimed technological advantage of online professional development (OPD) is the flexibility for educators to learn at a time and space of their convenience. However, the question of how, and with whom educators learn in OPD has received limited empirical attention. Using a participatory design approach, we explored the lived experiences and social networks of 19 educators following a formal OPD in a microcredential format. The mixed method study findings indicated that most (but not all) educators developed learning ties with their peers. This suggests that additional structural opportunities are needed to maintain social engagement in OPD. The findings will be of interest primarily to educators developing and delivering OPD, as well as current or potential professional learners who want to make the most out of OPD
