Two nations underground: building schools to survive nuclear war and desegregation in the 1960s

In the 1960s federal agencies in the United States encouraged the building of protected schools designed to survive a nuclear attack. A number of designs, including underground schools, were constructed. In order to promote the building of protected schools, the US government produced a number of propaganda films for school boards and governors. In addition to promoting post-nuclear survival, these films considered that protected schools were beneficial in terms of progressive and child-centred education and sometimes racial assimilation. This paper considers the extent to which securitisation and progressive education found a common purpose at this time and considers the implications of this for race equality. The data is based upon rare, archival film from the US National Archives in College Park, Maryland on school protection during the Cold War. These films, intended for wider public consumption were intended as promotional shorts for schools boards and other decision makers to show the advantages of adding fallout protection to school design. The method involved an archival search to scope the range of films produced at this time. Each film was viewed multiple times at the archive to transcribe text and image descriptions. This dual data was then used to form a narrative account of the argument structure of the films to identify the ways in which interest convergences and divergences around ‘race’ are deployed. The discussion uses conceptions of ‘flexible whiteness’ to examine how securitisation, a discourse identified with white hegemony, can additionally contain conceptions of race equality and progressivism

A Golden Age of Security and Education? Adult Education for Civil Defence in the United States 1950–1970

A number of authors consider that the early period of US security and education (1950–1970) was in some way a ‘golden age’ where there was a prevailing societal orientation towards civil defence. This is supported, to some extent, through ‘Duck and Cover’ type activities in schools and in community preparedness efforts. This article considers whether this portrayal is necessarily correct in the case of adult education. From an analysis of previously classified historical archives in the US National Archives II at the University of Maryland, I consider the success of the civil defense adult education programme (CDAE), and earlier adult education courses, from 1950 to 1970. Rather than being a ‘bottom-up’ process, CDAE was imposed on educators directly through an executive order. There was considerable resistance to the CDAE from other areas of government, from states and from students. CDAE had limited success only so much as the Department of Health and Welfare (DHEW) was able to reconcile it with their own educational objectives. The article concludes by considering the implications of these findings for contemporary adult education for emergencies

Creep and recovery in graphites at ambient temperature: an acoustic emission study

Nuclear graphites subject to compressive or tensile stress cycling show a Felicity effect, that is, acoustic emission (AE) is detected at stresses less than the previous peak stress. This is attributed to recovery processes that occur upon unloading and at zero stress. The extent of recovery increases with time (up to 105 mins) at zero stress between cycles. For two graphites (IM1-24 and PGA) held under constant compressive or tensile strain, AE over ∼16 h is attributed to creep. For the same graphites at zero stress (after application of a compressive or tensile prestress), AE over ∼16 h is attributed to creep recovery. Both types of AE time curve follow logarithmic rate laws similar to those derived earlier for high-temperature primary creep and creep recovery. The micromechanical processes that give rise to creep and AE on loading graphites are basal plane shear and microcracking; creep recovery is attributed to the reverse of these processes

Acoustic emission responses from cyclic loading of a nuclear graphite

An analysis is presented of acoustic emission from samples of a nuclear graphite, IMI-24, subjected to three consecutive, load-unload cycles to 5, 10, and 15 MPa, in tension, compression, and flexure. On the first cycle, cumulative acoustic emission events in all loading modes increased progressively from zero stress. However, in subsequent cycles, acoustic emission recurred at stresses approaching, but less than, the previous peak stresses (i.e., a Felicity effect was observed rather than a Kaiser effect). A new parameter, the Recovery ratio, B, is proposed for characterizing the pattern of acoustic emission on cyclic loading of graphites

Athletic pubalgia (sports hernia)

Athletic pubalgia or sports hernia is a syndrome of chronic lower abdomen and groin pain that may occur in athletes and nonathletes. Because the differential diagnosis of chronic lower abdomen and groin pain is so broad, only a small number of patients with chronic lower abdomen and groin pain fulfill the diagnostic criteria of athletic pubalgia (sports hernia). The literature published to date regarding the cause, pathogenesis, diagnosis, and treatment of sports hernias is confusing. This article summarizes the current information and our present approach to this chronic lower abdomen and groin pain syndrome

The application of Jäntti's method for the fast calculation of equilibrium in case of multilayer adsorption

On the basis of a molecular model for sorption kinetics Jäntti introduced a method to calculate equilibria shortly after a change of the pressure of the sorptive gas. In the present paper we apply that method for the description of multilayer adsorption
