The purpose of this paper is to investigate the possibility of in situ flaw detection for powder bed, beam‐based additive manufacturing processes using a thermal imaging system.

The authors compare infrared images (IR) which were taken during the generation of Ti‐6Al‐4V parts in a selective electron beam melting system (SEBM) with metallographic images taken from destructive material investigation.

A good match is found between the IR images and the material flaws detected by metallographic techniques.

First results are presented here, mechanisms of flaw formation and transfer between build layers are not addressed in detail.

This work has important implications for quality assurance in SEBM and rapid manufacturing in general.

The CW’s long-running horror-drama series Supernatural (2005–) has been accused of undoing progressive advances for women made by Buffy the Vampire Slayer (1996–2003). While it’s hard to deny the truth in that claim, Supernatural also problematizes conventional gender roles from a very different approach, one that plays with perceptions of masculinity and social class.

Buffy Summers may initially seem to have more in common with Supernatural’s Sam Winchester, a chosen one with special powers who wants a normal life away from the supernatural. However, Buffy shares more in common with Dean Winchester. Embodying popular gendered stereotypes in their introductions, it’s gradually revealed that there is more complexity to each. Both form alliances with Others; both recognize elements of the Other in themselves. Both transgress conventional gender boundaries, complicating the notion of a binary gender system. Both series introduce the seemingly familiar only to alter it into the uncanny. See the little cute blonde virginal cheerleader? She can kick your ass. See the stupid cocky womanizing jock? All he wants is family and a home. This chapter explores the increasingly gender-blended, social-class-crossing behaviours of Supernatural’s Dean Winchester as an heir to Buffy the Vampire Slayer.

The paper presents the concept of Solidarity Economy proposed by the Austrian-Brazilian economist and professor Paul Singer who passed away in 2018 at age 86 years in his home in São Paulo. Singer arrived at the concept of Solidarity Economy by mixing utopian socialist thought originated in Europe during the Industrial Revolution with the wisdom of Latin American working people to find alternative paths to the capitalist economic system. Following the teachings of Paul Singer, we, as practitioners and academics, report the first stage of the formation of a popular cooperative in the sector of recycling that occurred between 2019 and 2021 in the Town of Goiás, Goiás, Brazil. Our analysis of this collective endeavour leads to two main lessons: first, Solidarity Economy is an even broader proposal of an alternative to the capitalist economy than Paul Singer imagined, because its roots are not restricted to the European cooperativism of the nineteenth century, and second, economics must be taught in more popular way because the most urgent economic problems affect primarily the working people.

The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

As Lorna Jowett and Stacey Abbott have pointed out, the US TV serial Supernatural owes much of its success to the way it combines horror with family drama, strengthening the affective involvement of viewers in the lives of its protagonists, the monster-hunting Winchester brothers. The notion of home – presented variously as a domestic, feminine space from which the Winchesters and their compatriots are excluded; a mobile and contingent space of masculine bonding; and a hybrid space which allows for self-expression outside prescribed gender norms, but which also holds the potential for danger – is central.

Heather L. Duda has pointed to the ways monster hunters are excluded from the normative institutions of their societies, and this is certainly true of the Winchesters, who live in their family car and are unable to maintain ‘normal’ homes. Later seasons give them a home in the form of an underground bunker, not designed as a domestic space, but nonetheless a place where their hypermasculine behaviours can be relaxed. This chapter examines the tensions that emerge in this apparent move from a traditional narrative of the home as feminine space under threat to something more ambivalent, where masculine identity itself may be in danger.

There has been virtually no explication of poetry-writing pedagogy in historical accounts of Australian distance education during the 1930s. The purpose of this paper is to satisfy this gap in scholarship.

The paper concerns a particular episode in the cultural history of education; an episode upon which print media of the 1930s sheds a distinctive light. The paper therefore draws extensively on 1930s press reports to: contextualise the key educational debates and prime-movers inspiring verse-writing pedagogy in Australian education, particularly distance education, in order to; concentrate specific attention on the creation and popular reception of Brave Young Singers (1938), the first and only anthology of children's poetry written entirely by students of the correspondence classes of Western Australia.

Published under the auspices of the Australian Council for Educational Research (ACER) with funds originating from the Carnegie Corporation, two men in particular proved crucial to the development and culmination of Brave Young Singers. As the end result of a longitudinal study conducted by James Albert Miles with the particular support of Frank Tate, the publication attracted acclaim as a research document promoting ACER's success in educational research investigating the “experiment” of poetry-writing instruction through correspondence schooling.

The paper pays due critical attention to a previously overlooked anthology of Australian children's poetry while simultaneously presenting an original account of the emergence and implementation of verse-writing instruction within the Australian correspondence class curriculum of the 1930s.

The death of John F. Kennedy (JFK) was one of the most remarkable facts of the second half of the twentieth century. Not surprisingly, it was reflected numerous times in popular culture, including in popular music. In this chapter, I discuss songs published in the 1963–1968 period in which the image of JFK was represented as an idea, a cultural motif or a political myth created, transformed and maintained by artistic means. In song lyrics, a real person (who was a genuinely influential politician) was portrayed as a person who acquired a certain mythical status, stemming from JFK's charismatic features and augmented by his tragic death. Thus, separate from the real political career as the president, JFK serves as a kind of mythological structure used by several artists to generate meanings and mirror cultural iconography present in American culture.

Proposes that halfway through the decade which has been termed that of the brain, our level of understanding is still primitive despite much excellent research. Discusses new findings, such as those presented in a recent lecture, which can still alter profoundly the perception of neural mechanisms, and shows that we may even be wrong in the customary assumption that the well‐known electro‐chemical neural transmission is the only important form of rapid internal communication in the brain.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Life studies are a rich source for further research on the role of the Afro‐American woman in society. They are especially useful to gain a better understanding of the Afro‐American experience and to show the joys, sorrows, needs, and ideals of the Afro‐American woman as she struggles from day to day.
