Strong Angels of Comfort: Middle Class Managing Daughters in Victorian Literature

This dissertation joins a vibrant conversation in the social sciences about the challenging nature of care labor as well as feminist discussions about the role of the daughter in Victorian culture. It explores the literary presence of the middle class managing daughter in the Victorian home. Collectively, the novels in this study articulate social anxieties about the unclear and unstable role of daughters in the family, the physically and emotionally challenging work they, and all women, do, and the struggle for daughters to find a place in a family hierarchy, which is often structured not by effort or affection, but by proscribed traditional roles, which do not easily adapt to managing daughters, even if they are the ones holding the family together. The managing daughter is a problem not accounted for in any conventional domestic structure or ideology so there is no role, no clear set of responsibilities and no boundaries that could, and arguably should, define her obligations, offer her opportunities for empowerment, or set necessary limits on the broad cultural mandate she has to comfort and care others. The extremes she is often pushed to reveals the stresses and hidden conflicts for authority and autonomy inherent in domestic labor without the iconic angel in the house rhetoric that so often masks the difficulties of domestic life for women. She gains no authority or stability no matter how loving or even how necessary she is to a family because there simply is no position in the parental family structure for her. The managing daughter thus reveals a deep crack in the structure of the traditional Victorian family by showing that it often cannot accommodate, protect, or validate a loving non-traditional family member because it values traditional hierarchies over emotion or effort. Yet, in doing so, it also suggests that if it is position not passion that matters, then as long as a woman assumes the right position in the family then deep emotional connections to others are not necessary for her to care competently for others

The Pandora SmallSat: Multiwavelength Characterization of Exoplanets and their Host Stars

Pandora is a SmallSat mission concept, selected as part of NASA’s Astrophysics Pioneers Program, designed to study the atmospheres of exoplanets using transmission spectroscopy. Transmission spectroscopy of transiting exoplanets provides our best opportunity to identify the makeup of planetary atmospheres in the coming decade. Stellar brightness variations due to star spots, however, can seep into these measurements and contaminate the observed spectra. Pandora is designed to disentangle star and planet signals in transmission spectra and reliably characterize the planetary atmospheres. Pandora will collect long-duration photometric observations with a visible-light channel, and simultaneous spectra with a near-IR channel, where water is a strong molecular absorber. The broad wavelength coverage will provide constraints on spot covering fractions of the stars and determine the impact of these active regions on the planetary spectra. Pandora will observe at least 20 exoplanets with sizes ranging from Earth-size to Jupiter-size, with host stars spanning mid-K to late-M spectral types. The project is made possible by leveraging investments in other projects, including an all-aluminum 0.45-meter Cassegrain telescope design, and an IR sensor chip assembly from the James Webb Space Telescope. The mission will last five years from initial formulation to closeout, with one-year of science operations. Launch is planned for the mid-2020s as a secondary payload in Sun-synchronous low-Earth orbit. By design, Pandora has a diverse team, with over half of mission leadership roles filled by early career scientists and engineers, demonstrating the high value of SmallSats for developing the next generation of space mission leaders

Two Warm Super-Earths Transiting the Nearby M Dwarf TOI-2095

We report the detection and validation of two planets orbiting TOI-2095 (TIC 235678745). The host star is a 3700K M1V dwarf with a high proper motion. The star lies at a distance of 42 pc in a sparsely populated portion of the sky and is bright in the infrared (K=9). With data from 24 Sectors of observation during TESS's Cycles 2 and 4, TOI-2095 exhibits two sets of transits associated with super-Earth-sized planets. The planets have orbital periods of 17.7 days and 28.2 days and radii of 1.30 and 1.39 Earth radii, respectively. Archival data, preliminary follow-up observations, and vetting analyses support the planetary interpretation of the detected transit signals. The pair of planets have estimated equilibrium temperatures of approximately 400 K, with stellar insolations of 3.23 and 1.73 times that of Earth, placing them in the Venus zone. The planets also lie in a radius regime signaling the transition between rock-dominated and volatile-rich compositions. They are thus prime targets for follow-up mass measurements to better understand the properties of warm, transition radius planets. The relatively long orbital periods of these two planets provide crucial data that can help shed light on the processes that shape the composition of small planets orbiting M dwarfs.Comment: Submitted to AAS Journal

Magnetic Fields toward Ophiuchus-B Derived from SCUBA-2 Polarization Measurements

We present the results of dust emission polarization measurements of Ophiuchus-B (Oph-B) carried out using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) camera with its associated polarimeter (POL-2) on the James Clerk Maxwell Telescope in Hawaii. This work is part of the B-fields in Star-forming Region Observations survey initiated to understand the role of magnetic fields in star formation for nearby star-forming molecular clouds. We present a first look at the geometry and strength of magnetic fields in Oph-B. The field geometry is traced over ~0.2 pc, with clear detection of both of the sub-clumps of Oph-B. The field pattern appears significantly disordered in sub-clump Oph-B1. The field geometry in Oph-B2 is more ordered, with a tendency to be along the major axis of the clump, parallel to the filamentary structure within which it lies. The degree of polarization decreases systematically toward the dense core material in the two sub-clumps. The field lines in the lower density material along the periphery are smoothly joined to the large-scale magnetic fields probed by NIR polarization observations. We estimated a magnetic field strength of 630 ± 410 μG in the Oph-B2 sub-clump using a Davis–Chandrasekhar–Fermi analysis. With this magnetic field strength, we find a mass-to-flux ratio λ = 1.6 ± 1.1, which suggests that the Oph-B2 clump is slightly magnetically supercritical

Aortic waveform responses to insulin in late versus early chronotype with metabolic syndrome

Abstract Late chronotype (LC) correlates with reduced metabolic insulin sensitivity and cardiovascular disease. It is unclear if insulin action on aortic waveforms and inflammation is altered in LC versus early chronotype (EC). Adults with metabolic syndrome (n = 39, MetS) were classified as either EC (Morning‐Eveningness Questionnaire [MEQ] = 63.5 ± 1.2) or LC (MEQ = 45.5 ± 1.3). A 120 min euglycemic clamp (40 mU/m2/min, 90 mg/dL) with indirect calorimetry was used to determine metabolic insulin sensitivity (glucose infusion rate [GIR]) and nonoxidative glucose disposal (NOGD). Aortic waveforms via applanation tonometry and inflammation by blood biochemistries were assessed at 0 and 120 min of the clamp. LC had higher fat‐free mass and lower VO2max, GIR, and NOGD (between groups, all p ≤ 0.05) than EC. Despite no difference in 0 min waveforms, both groups had insulin‐stimulated elevations in pulse pressure amplification with reduced AIx75 and augmentation pressure (AP; time effect, p ≤ 0.05). However, EC had decreased forward pressure (Pf; interaction effect, p = 0.007) with insulin versus rises in LC. Although LC had higher tumor necrosis factor‐α (TNF‐α; group effect, p ≤ 0.01) than EC, both LC and EC had insulin‐stimulated increases in TNF‐α and decreases in hs‐CRP (time effect, both p ≤ 0.01). Higher MEQ scores related to greater insulin‐stimulated reductions in AP (r = −0.42, p = 0.016) and Pf (r = −0.41, p = 0.02). VO2max correlated with insulin‐mediated reductions in AIx75 (r = −0.56, p < 0.01) and AP (r = −0.49, p < 0.01). NOGD related to decreased AP (r = −0.44, p = 0.03) and Pf (r = −0.43, p = 0.04) during insulin infusion. LC was depicted by blunted forward pressure waveform responses to insulin and higher TNF‐α in MetS. More work is needed to assess endothelial function across chronotypes

Factors Associated With Surveillance Testing in Individuals With COVID-19 Symptoms During the Last Leg of the Pandemic: Multivariable Regression Analysis

Abstract BackgroundRural underserved areas facing health disparities have unequal access to health resources. By the third and fourth waves of SARS-CoV-2 infections in the United States, COVID-19 testing had reduced, with more reliance on home testing, and those seeking testing were mostly symptomatic. ObjectiveThis study identifies factors associated with COVID-19 testing among individuals who were symptomatic versus asymptomatic seen at a Rapid Acceleration of Diagnostics for Underserved Populations phase 2 (RADx-UP2) testing site in West Virginia. MethodsDemographic, clinical, and behavioral factors were collected via survey from tested individuals. Logistic regression was used to identify factors associated with the presence of individuals who were symptomatic seen at testing sites. Global tests for spatial autocorrelation were conducted to examine clustering in the proportion of symptomatic to total individuals tested by zip code. Bivariate maps were created to display geographic distributions between higher proportions of tested individuals who were symptomatic and social determinants of health. ResultsAmong predictors, the presence of a physical (adjusted odds ratio [aOR] 1.85, 95% CI 1.3-2.65) or mental (aOR 1.53, 95% CI 0.96-2.48) comorbid condition, challenges related to a place to stay/live (aOR 307.13, 95% CI 1.46-10,6372), no community socioeconomic distress (aOR 0.99, 95% CI 0.98-1.00), no challenges in getting needed medicine (aOR 0.01, 95% CI 0.00-0.82) or transportation (aOR 0.23, 95% CI 0.05-0.64), an interaction between community socioeconomic distress and not getting needed medicine (aOR 1.06, 95% CI 1.00-1.13), and having no community socioeconomic distress while not facing challenges related to a place to stay/live (aOR 0.93, 95% CI 0.87-0.99) were statistically associated with an individual being symptomatic at the first test visit. ConclusionsThis study addresses critical limitations to the current COVID-19 testing literature, which almost exclusively uses population-level disease screening data to inform public health responses

Outcomes of patients with diffuse large B-cell and high-grade B-cell lymphomas with synchronous CNS and systemic involvement at diagnosis treated with high-dose methotrexate and R-CHOP: a single-center retrospective study

Background: The optimal treatment of patients with systemic diffuse large B-cell (DLBCL) or high-grade B-cell (HGBL) lymphomas with synchronous central nervous system (CNS) involvement at diagnosis is not well defined. High-dose methotrexate administered concurrently with R-CHOP (RM-CHOP) is a commonly used regimen, but data on outcomes achieved with this regimen are limited. Objective: To report our experience with RM-CHOP in patients with systemic DLBCL or HGBL with synchronous CNS involvement at diagnosis. Design: A single-center retrospective analysis. Methods: We identified consecutive patients with systemic DLBCL or HGBL with synchronous CNS involvement at diagnosis who were treated with RM-CHOP from January 2012 to January 2021. Results: Fifty patients were included with a median age of 62 years; 82% had DLBCL ( n  = 41) and 18% had HGBL ( n  = 9). Treatment with RM-CHOP was followed by consolidative autologous hematopoietic cell transplantation in 14 patients (28%). The complete response (CR) rate following RM-CHOP was 62%. With a median follow-up of 40 months, the median progression-free (PFS) and overall (OS) survivals were 16 and 58 months, and the 2-year PFS and OS were 41% and 57%, respectively. The 2-year cumulative incidence of CNS progression/relapse was 29%. Outcomes were particularly poor in HGBL, with median PFS and OS of 6 and 7 months, compared with median PFS and OS of 22 months and not reached in DLBCL, respectively. The outcomes of patients with relapsed/progressive disease were poor, with only 63% of patients receiving subsequent treatments and only 21% achieving CR to next subsequent treatment. Most patients (58%) with disease relapse/progression had CNS involvement which was associated with very poor outcomes (median OS of 2 months). Conclusion: CNS involvement in aggressive B-cell non-Hodgkin lymphoma at diagnosis dictates clinical outcomes and requires more effective treatment options
