#MeToo in EM: A Multicenter Survey of Academic Emergency Medicine Faculty on Their Experiences with Gender Discrimination and Sexual Harassment
Introduction: Gender-based discrimination and sexual harassment of female physicians are well documented. The #MeToo movement has brought renewed attention to these problems. This study examined academic emergency physiciansâ experiences with workplace gender discrimination and sexual harassment.Methods: We conducted a cross-sectional survey of a convenience sample of emergency medicine (EM) faculty across six programs. Survey items included the following: the Overt Gender Discrimination at Work (OGDW) Scale; the frequency and source of experienced and observed discrimination; and whether subjects had encountered unwanted sexual behaviors by a work superior or colleague in their careers. For the latter question, we asked subjects to characterize the behaviors and whether those experiences had a negative effect on their self-confidence and career advancement. We made group comparisons using t-tests or chi-square analyses, and evaluated relationships between gender and physiciansâ experiences using correlation analyses.Results: A total of 141 out of 352 (40.1%) subjects completed at least a portion of the survey. Women reported higher mean OGDW scores than men (15.4 vs 10.2; 95% confidence interval [CI], 3.6â6.8). Female faculty were also more likely to report having experienced gender-based discriminatory treatment than male faculty (62.7% vs 12.5%; 95% CI, 35.1%-65.4%), although male and female faculty were equally likely to report having observed gender-based discriminatory treatment of another physician (64.7% vs 56.3%; 95% CI, 8.6%-25.5%). The three most frequent sources of experienced or observed gender-based discriminatory treatment were patients, consulting or admitting physicians, and nursing staff. The majority of women reported having encountered unwanted sexual behaviors in their careers, with a significantly greater proportion of women reporting them compared to men (52.9% vs 26.2%, 95% CI, 9.9%-43.4%). The majority of unwanted behaviors were sexist remarks and sexual advances. Of those respondents who encountered these unwanted behaviors, 22.9% and 12.5% reported at least somewhat negative effects on their self-confidence and career advancement.Conclusion: Female EM faculty perceived more gender-based discrimination in their workplaces than their male counterparts. The majority of female and approximately a quarter of male EM faculty encountered unwanted sexual behaviors in their careers.
A Search for Variable Stars in the Globular Cluster M4 with K2
We extract light curves for 4554 objects with in the K2 superstamp
observations of the globular cluster M4, including 3784 cluster members, and
search for variability. Among cluster member objects, we detect 66 variables,
of which 52 are new discoveries. Among objects not belonging to the cluster, we
detect 24 variables, of which 20 are new discoveries. We additionally discover
57 cluster-member suspected variables, 10 cluster-non-member suspected
variables, and four variables with ambiguous cluster membership. Our light
curves reach sub-millimagnitude precision for the cluster horizontal branch,
permitting us to detect asteroseismic activity in six horizontal branch stars
outside the instability strip and one inside the strip but with only ~1 mmag
amplitude variability. 19 additional stars along the red giant branch also have
detected asteroseismic variability. Several eclipsing binaries are found in the
cluster, including a 4.6-day detached eclipsing binary and an EW-class
eclipsing binary, as well as an EW with uncertain cluster membership and three
other candidate EWs. A 22-day detached eclipsing binary is also found outside
the cluster. We identify a candidate X-ray binary that is a cluster member with
quiescent and periodic ~20 mmag optical variability. We also obtain
high-precision light curves for ten of the previously known RR Lyrae variables
in the cluster and identify one as a candidate Blazhko variable with a Blazhko
period in excess of 78 days. We make our light curves publicly available.Comment: 48 pages, 21 figures, 5 tables; online material: Table 1 and light

Lip plumper contact urticaria.
Lip plumpers are relatively new topical agents on the market that are designed to increase lip volume minutes to days after application. In this report, we describe a case of lip plumper contact urticaria in a young boy. We also discuss the mechanisms of action of lip plumpers and the sociocultural reasons for their use
Orbital Orientations of Exoplanets: HAT-P-4b is Prograde and HAT-14b is Retrograde
We present observations of the Rossiter-McLaughlin effect for two exoplanetary systems, revealing the orientations of their orbits relative to the rotation axes of their parent stars. HAT-P-4b is prograde, with a sky-projected spin-orbit angle of λ = â4.9 ± 11.9 deg. In contrast, HAT-P-14b is retrograde, with λ = 189.1 ± 5.1 deg. These results conform with a previously noted pattern among the stellar hosts of close-in giant planets: hotter stars have a wide range of obliquities and cooler stars have low obliquities. This, in turn, suggests that three-body dynamics and tidal dissipation are responsible for the short-period orbits of many exoplanets. In addition, our data revealed a third body in the HAT-P-4 system, which could be a second planet or a companion star
A Search for Variable Stars in the Globular Cluster M4 with K2
We extract light curves for 4554 objects with 9 < G < 19 in the K2 superstamp observations of the globular cluster M4, including 3784 cluster members, and search for variability. Among cluster-member objects, we detect 66 variables, of which 52 are new discoveries. Among objects not belonging to the cluster, we detect 24 variables, of which 20 are new discoveries. We additionally discover 57 cluster-member suspected variables, 10 cluster-non-member suspected variables, and four variables with ambiguous cluster membership. Our light curves reach sub-millimagnitude precision for the cluster horizontal branch, permitting us to detect asteroseismic activity in six horizontal branch stars outside the instability strip and one inside the strip but with only similar to 1 mmag amplitude variability. Nineteen additional stars along the red giant branch also have detected asteroseismic variability. Several eclipsing binaries are found in the cluster, including a 4.6 day detached eclipsing binary and an EW-class eclipsing binary, as well as an EW with uncertain cluster membership and three other candidate EWs. A 22 day detached eclipsing binary is also found outside the cluster. We identify a candidate X-ray binary that is a cluster member with quiescent and periodic similar to 20 mmag optical variability. We also obtain high-precision light curves for 10 of the previously known RR Lyrae variables in the cluster and identify one as a candidate Blazhko variable with a Blazhko period in excess of 78 days. We make our light curves publicly available
The Transit Light Curve Project. IV. Five Transits of the Exoplanet OGLE-TR-10b
We present I and B photometry of five distinct transits of the exoplanet
OGLE-TR-10b. By modeling the light curves, we find the planetary radius to be
R_P = 1.06 +/- 0.08 R_Jup and the stellar radius to be R_S = 1.10 +/- 0.07
R_sun. The uncertainties are dominated by statistical errors in the photometry.
Our estimate of the planetary radius is smaller than previous estimates that
were based on lower-precision photometry, and hence the planet is not as
anomalously large as was previously thought. We provide updated determinations
of all the system parameters, including the transit ephemerides.Comment: Accepted in the Astrophysical Journal, 23 October 2006. Includes
observations of additional transits to confirm earlier results. [15 pg, 6

A High Stellar Obliquity in the WASP-7 Exoplanetary System
We measure a tilt of 86+-6 deg between the sky projections of the rotation
axis of the WASP-7 star, and the orbital axis of its close-in giant planet.
This measurement is based on observations of the Rossiter-McLaughlin (RM)
effect with the Planet Finder Spectrograph on the Magellan II telescope. The
result conforms with the previously noted pattern among hot-Jupiter hosts,
namely, that the hosts lacking thick convective envelopes have high
obliquities. Because the planet's trajectory crosses a wide range of stellar
latitudes, observations of the RM effect can in principle reveal the stellar
differential rotation profile; however, with the present data the signal of
differential rotation could not be detected. The host star is found to exhibit
radial-velocity noise (``stellar jitter') with an amplitude of ~30m/s over a
timescale of days.Comment: ApJ accepted, 9 pages, 9 figure
