Making a Difference: The History and Memory of ‘Women Strike for Peace’, 1961-1990

The women’s antinuclear protest group Women Strike for Peace (WSP) formed a visible part of the US peace movement during the Cold War, recording several successes and receiving a positive historical assessment for its maternal, respectable image. This study provides a revised history of WSP, querying the identity of the group in order to produce a more comprehensive and problematic historical narrative. It is the first study to examine WSP from its founding in 1961 through to the closure of its National Office in 1990. The thesis examines key events in the group’s history and challenges established historical understandings of the group, positing that existing perceptions offer an image of uniformity that overlooks the differing experiences of WSP activists and the complexity of their memories. This study draws on aspects of memory theory to inform its examination of WSP’s historical record. It contends that social influences and personal identity had a significant impact on the way in which former members recalled their experiences, while assessing the relationship between collective and individual identity within WSP. By placing the group into the changing cultural and societal environment of Cold War America, this thesis is the first to demonstrate the importance of contextual background to understanding the development of WSP activists’ memory and identity. Whereas existing examinations of Women Strike for Peace apply its maternal image to the entirety of its history, this study finds such interpretations of identity and historical understanding to be static and argues that the transformation in activist identities informed changing perceptions of the group’s past successes. The thesis makes extensive use of branch records and the recollections of individuals recorded through oral interviews and memoirs to query established understandings of WSP. It finds that the desire of leading figures to project a moderate, maternal image resulted in the establishment of a framework within which WSP activists understood their identity and activism. This framework resulted in an historical narrative that overlooks the diversity within the group, the tensions between members that emerged over issues such as hierarchical structure, civil disobedience, and feminist activism, and the regional disparity of the national organisation. The perspectives of leading figures have often been consulted to the detriment of grassroots voices that can offer a more complex, contentious depiction of WSP’s history. Accounting for the construction of WSP’s history, memory, and identity, this thesis challenges our view of the experience of peace activism in the 20th century United States

Accuracy and repeatability of wrist joint angles in boxing using an electromagnetic tracking system

© 2019, The Author(s). The hand-wrist region is reported as the most common injury site in boxing. Boxers are at risk due to the amount of wrist motions when impacting training equipment or their opponents, yet we know relatively little about these motions. This paper describes a new method for quantifying wrist motion in boxing using an electromagnetic tracking system. Surrogate testing procedure utilising a polyamide hand and forearm shape, and in vivo testing procedure utilising 29 elite boxers, were used to assess the accuracy and repeatability of the system. 2D kinematic analysis was used to calculate wrist angles using photogrammetry, whilst the data from the electromagnetic tracking system was processed with visual 3D software. The electromagnetic tracking system agreed with the video-based system (paired t tests) in both the surrogate ( 0.9). In the punch testing, for both repeated jab and hook shots, the electromagnetic tracking system showed good reliability (ICCs > 0.8) and substantial reliability (ICCs > 0.6) for flexion–extension and radial-ulnar deviation angles, respectively. The results indicate that wrist kinematics during punching activities can be measured using an electromagnetic tracking system

Defending the digital: Awareness of digital selectivity in historical research practice

Existing research offers fearful conclusions on the use of online archival collections, finding that historians ignore and overlook the limitations of digital sources. However, an attitudinal case study at Newcastle University contradicts this consensus. This article discusses this study’s detailed findings, determining that historians and library professionals demonstrate abundant and nuanced awareness of issues relating to ‘digital selectivity’. Nevertheless, the interviewees suggested that this does not radically undermine their practice. The study also revealed compelling aspects of digital selectivity not currently observed in existing research, including the effects of career stage and the importance of cooperation with library professionals. While the existing literature provides appropriate and prudent concerns, it lacks tangible evidence pointing to a widespread phenomenon of poor digital historical practice. The article closes by recommending further research into historians’ digital information-seeking behaviour, but argues that standardized metadata practices must come first. Limitations, including the absence of rigorous quantitative data, must be resolved before a fuller appreciation for digital historical practice is developed

NuSTAR discovery of a luminosity dependent cyclotron line energy in Vela X-1

We present NuSTAR observations of Vela X-1, a persistent, yet highly variable, neutron star high-mass X-ray binary (HMXB). Two observations were taken at similar orbital phases but separated by nearly a year. They show very different 3–79 keV flux levels as well as strong variability during each observation, covering almost one order of magnitude in flux. These observations allow, for the first time ever, investigations on kilo-second time-scales of how the centroid energies of cyclotron resonant scattering features (CRSFs) depend on flux for a persistent HMXB. We find that the line energy of the harmonic CRSF is correlated with flux, as expected in the sub-critical accretion regime. We argue that Vela X-1 has a very narrow accretion column with a radius of around 0.4 km that sustains a Coulomb interaction dominated shock at the observed luminosities of L_x ~ 3 × 10^36 erg s^−1. Besides the prominent harmonic line at 55 keV the fundamental line around 25 keV is clearly detected. We find that the strengths of the two CRSFs are anti-correlated, which we explain by photon spawning. This anti-correlation is a possible explanation for the debate about the existence of the fundamental line. The ratio of the line energies is variable with time and deviates significantly from 2.0, also a possible consequence of photon spawning, which changes the shape of the line. During the second observation, Vela X-1 showed a short off-state in which the power-law softened and a cut-off was no longer measurable. It is likely that the source switched to a different accretion regime at these low mass accretion rates, explaining the drastic change in spectral shape

Effect of Hydrocortisone on Mortality and Organ Support in Patients With Severe COVID-19: The REMAP-CAP COVID-19 Corticosteroid Domain Randomized Clinical Trial.

Importance: Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited. Objective: To determine whether hydrocortisone improves outcome for patients with severe COVID-19. Design, Setting, and Participants: An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin. Between March 9 and June 17, 2020, 614 adult patients with suspected or confirmed COVID-19 were enrolled and randomized within at least 1 domain following admission to an intensive care unit (ICU) for respiratory or cardiovascular organ support at 121 sites in 8 countries. Of these, 403 were randomized to open-label interventions within the corticosteroid domain. The domain was halted after results from another trial were released. Follow-up ended August 12, 2020. Interventions: The corticosteroid domain randomized participants to a fixed 7-day course of intravenous hydrocortisone (50 mg or 100 mg every 6 hours) (n = 143), a shock-dependent course (50 mg every 6 hours when shock was clinically evident) (n = 152), or no hydrocortisone (n = 108). Main Outcomes and Measures: The primary end point was organ support-free days (days alive and free of ICU-based respiratory or cardiovascular support) within 21 days, where patients who died were assigned -1 day. The primary analysis was a bayesian cumulative logistic model that included all patients enrolled with severe COVID-19, adjusting for age, sex, site, region, time, assignment to interventions within other domains, and domain and intervention eligibility. Superiority was defined as the posterior probability of an odds ratio greater than 1 (threshold for trial conclusion of superiority >99%). Results: After excluding 19 participants who withdrew consent, there were 384 patients (mean age, 60 years; 29% female) randomized to the fixed-dose (n = 137), shock-dependent (n = 146), and no (n = 101) hydrocortisone groups; 379 (99%) completed the study and were included in the analysis. The mean age for the 3 groups ranged between 59.5 and 60.4 years; most patients were male (range, 70.6%-71.5%); mean body mass index ranged between 29.7 and 30.9; and patients receiving mechanical ventilation ranged between 50.0% and 63.5%. For the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively, the median organ support-free days were 0 (IQR, -1 to 15), 0 (IQR, -1 to 13), and 0 (-1 to 11) days (composed of 30%, 26%, and 33% mortality rates and 11.5, 9.5, and 6 median organ support-free days among survivors). The median adjusted odds ratio and bayesian probability of superiority were 1.43 (95% credible interval, 0.91-2.27) and 93% for fixed-dose hydrocortisone, respectively, and were 1.22 (95% credible interval, 0.76-1.94) and 80% for shock-dependent hydrocortisone compared with no hydrocortisone. Serious adverse events were reported in 4 (3%), 5 (3%), and 1 (1%) patients in the fixed-dose, shock-dependent, and no hydrocortisone groups, respectively. Conclusions and Relevance: Among patients with severe COVID-19, treatment with a 7-day fixed-dose course of hydrocortisone or shock-dependent dosing of hydrocortisone, compared with no hydrocortisone, resulted in 93% and 80% probabilities of superiority with regard to the odds of improvement in organ support-free days within 21 days. However, the trial was stopped early and no treatment strategy met prespecified criteria for statistical superiority, precluding definitive conclusions.

“I Have Chosen the Flaming Death”: The Forgotten Self‐Immolation of Alice Herz

In March 1965, 82‐year‐old peace activist Alice Herz immolated herself in opposition to US military action in Vietnam. Her protest followed similar public displays by Vietnamese Buddhists, but was an unprecedented form of protest in the United States. However, while it provoked sympathy from international observers, the US public reacted with ambivalence. Herz's legacy subsequently became overshadowed after Norman Morrison's identical protest in November that year. This article accounts for the multiple reactions to Alice Herz's forgotten self‐immolation. It examines both the international and domestic context to highlight the cultural norms, political context, gender dynamics, and performative factors that influenced responses to the act. Using Morrison's example to show how responses were formed, this article reveals that because Herz did not receive contemporary interest she has been overlooked historically
