The Clinical Sociology of George Edmund Haynes

This paper examines the career and approach to clinical sociology adopted by George Edmund Haynes in the first half of the 20th century. The presentation focuses on Haynes\u27 career as a sociologist, in which he taught and promoted the social sciences at Fisk University, his work in the federal government as a special assistant to the Secretary of Labor and Director of Economics, and his tenure as Executive Secretary of the Commission on Race Relations at the Federal Council of Churches in America, where he conducted an active research program of applying his sociological skills to concrete problems within the context of the religious ideals of the church. Also described are various strategies and programs Haynes advocated in his clinical approach to reforming interracial relations

When fear of failure leads to intentions to act entrepreneurially: Insights from threat appraisals and coping efficacy

Calls in the entrepreneurship literature have advocated theory development and empirical studies exploring fear of failure. Often viewed as an inhibitory factor towards entrepreneurial activity, contemporary research has suggested that fear of failure can also motivate entrepreneurial activity. To explore this issue, we draw on Protection Motivation Theory to conceptualise and operationalise fear of failure. We find support for the notion that fear of failure prompts the adoption of entrepreneurial strategies, provided the entrepreneur believes they have the ability to act entrepreneurially, and that by so doing, their financial situation will improve. Our approach extends the literature on fear of failure in an entrepreneurship context by disentangling cognitive and behavioural aspects focusing not only on threat appraisals, but also on how entrepreneurs cope with them

The Power of Feminist Judgments?

Recent years have seen the advent of two feminist judgment-writing projects, the Women’s Court of Canada, and the Feminist Judgments Project in England. This article analyses these projects in light of Carol Smart’s feminist critique of law and legal reform and her proposed feminist strategies in Feminism and the Power of Law (1989). At the same time, it reflects on Smart’s arguments 20 years after their first publication and considers the extent to which feminist judgment-writing projects may reinforce or trouble her conclusions. It argues that both of these results are discernible—that while some of Smart’s contentions have proved to be unsustainable, others remain salient and have both inspired and hold important cautions for feminist judgment-writing projects

First-time Diabetic Ketoacidosis in Type 2 Diabetics with COVID-19 Infection: A Novel Case Series

Background: SARS-CoV-2 is a novel coronavirus first diagnosed in US hospitals in January 2020. Typical presenting symptoms include fever, dry cough, dyspnea, and hypoxia. However, several other symptoms have been reported, including fatigue, weakness, diarrhea, and abdominal pain. We have identified a series of patients with diabetic ketoacidosis (DKA) likely precipitated by COVID-19. Case Series: We describe five patients with previously known type 2 diabetes and no history of DKA, who presented to the emergency department with new-onset DKA and COVID-19. Why should an emergency physician be aware of this?: Diabetes mellitus is a known risk factor for poor outcomes in viral respiratory illnesses, including COVID-19. Infection may precipitate DKA in patients with type 2 diabetes. Aggressive management of these patients is recommended; however, management guidelines have not yet been put forth for this unique subset of patients

Spindown of massive rotating stars

Models of rapidly rotating massive stars at low metallicities show significantly different evolution and higher metal yields compared to non-rotating stars. We estimate the spin-down time-scale of rapid rotating non-convective stars supporting an alpha-Omega dynamo. The magnetic dynamo gives rise to mass loss in a magnetically controlled stellar wind and hence stellar spin down owing to loss of angular momentum. The dynamo is maintained by strong horizontal rotation-driven turbulence which dominates over the Parker instability. We calculate the spin-down time-scale and find that it could be relatively short, a small fraction of the main-sequence lifetime. The spin-down time-scale decreases dramatically for higher surface rotations suggesting that rapid rotators may only exhibit such high surface velocities for a short time, only a small fraction of their main-sequence lifetime.Comment: Accepted by MNRA

Extremely Inefficient Star Formation in the Outer Disks of Nearby Galaxies

(Abridged) We combine data from The HI Nearby Galaxy Survey and the GALEX Nearby Galaxy Survey to study the relationship between atomic hydrogen (HI) and far-ultraviolet (FUV) emission outside the optical radius (r25) in 17 spiral and 5 dwarf galaxies. In this regime, HI is likely to represent most of the ISM and FUV emission to trace recent star formation with little bias due to extinction, so that the two quantities closely trace the underlying relationship between gas and star formation rate (SFR). The azimuthally averaged HI and FUV intensities both decline with increasing radius in this regime, with the scale length of the FUV profile typically half that of the HI profile. Despite the mismatch in profiles, there is a significant spatial correlation (at 15" resolution) between local FUV and HI intensities; near r25 this correlation is quite strong, in fact stronger than anywhere inside r25, and shows a decline towards larger radii. The star formation efficiency (SFE) - defined as the ratio of FUV/HI and thus the inverse of the gas depletion time - decreases with galactocentric radius across the outer disks, though much shallower than across the optical disks. On average, we find the gas depletion times to be well above a Hubble time (~10^11 yr). We observe a clear relationship between FUV/HI and HI column in the outer disks, with the SFE increasing with increasing HI column. Despite observing systematic variations in FUV/HI, we find no clear evidence for step-function type star formation thresholds. When compared with results from inside r25, we find outer disk star formation to be distinct in several ways: it is extremely inefficient (depletion times of many Hubble times) with column densities and SFRs lower than found anywhere inside the optical disks. It appears that the HI column is one of, perhaps even the key environmental factor in setting the SFR in outer galaxy disks.Comment: Accepted for Publication in The Astronomical Journa

Gas Metallicities in the Extended Disks of NGC 1512 and NGC 3621. Chemical Signatures of Metal Mixing or Enriched Gas Accretion?

(Abridged) We have obtained spectra of 135 HII regions located in the inner and extended disks of the spiral galaxies NGC 1512 and NGC 3621, spanning the range of galactocentric distances 0.2-2 x R25 (from 2-3 kpc to 18-25 kpc). We find that the excitation properties of nebulae in the outer (R>R25) disks are similar to those of the inner disks, but on average younger HII regions tend to be selected in the bright inner disks. Reddening by dust is not negligible in the outer disks, and subject to significant large-scale spatial variations. For both galaxies the radial abundance gradient flattens to a constant value outside of the isophotal radius. The outer disk O/H abundance ratio is highly homogeneous, with a scatter of only ~0.06 dex. Based on the excitation and chemical (N/O ratio) analysis we find no compelling evidence for variations in the upper initial mass function of the ionizing clusters of extended disks. The O/H abundance in the outer disks of the target galaxies corresponds to 35% of the solar value (or higher, depending on the metallicity diagnostic). This conflicts with the notion that metallicities in extended disks of spiral galaxies are necessarily low. The observed metal enrichment cannot be produced with the current level of star formation. We discuss the possibility that metal transport mechanisms from the inner disks lead to metal pollution of the outer disks. Gas accretion from the intergalactic medium, enriched by outflows, offers an alternative solution.Comment: Accepted for publication in the Astrophysical Journa
