The rules and regulations inherent to the design pressures and scantlings of high-speed powercrafts are numerous, and regularly reviewed. Recently, the new ISO 12215-5:2019 made notable changes to the way high-speed crafts are analysed, including extending the acceleration experienced up to 8 g in certain circumstances. Nevertheless, despite the multiple iterations and variety of regulatory bodies, the seminal work undertaken on planing crafts throughout the 1960s and 1970s remains the foundation of any rule-based design requirement. Consequently, this paper investigates an array of recently published rules though a comparative design case study, the current state-of-the-art across a number of regulations, and the ultimate impact on scantlings. The study reveals that, despite divergence in intermediate calculations and assumptions, similar requirements are ultimately achieved. Eventually, discussion on the comparison undertaken and future trends in high-speed marine vehicles is provided, tackling the relevance of classical planing theory in light of contemporary innovations.

<p>Aotearoa New Zealand is a society with inequality deeply embedded in its culture, and this translates to the health of vulnerable members of the community. In its current state, healthcare infrastructure and rehabilitative landscapes are isolated from one another, creating physical and mental barriers for achieving well-being. Therapeutic landscape research suggests outdoor spaces can facilitate rehabilitative healing, community support, and self-empowerment. This form of preventive and rehabilitative health may bridge the gap between treatment at the institutional level, and day-to-day living, to better support the well-being, of people in transition.  The under-utilized interface between the residential landscape and Kenepuru Community Hospital in Porirua is used as a design case study, for testing how hospital infrastructure, residential housing, and therapeutic landscapes may coexist for mutually beneficial health and well-being outcomes. Results suggest that careful design of the interstitial spaces bridging housing with healthcare can form an important service for the well-being of vulnerable people.</p>

The current state of the radical left and, more broadly, politics in Scotland has its roots in the unique set of political, economic and intellectual conditions found in the 1960s and 1970s. Where mainstream accounts of the origins and development of Scottish nationalism - and its increasing popularity on the left - emphasise political and economic origins in these decades, this chapter emphasises the equally crucial intellectual developments of the period. Khruschev’s ‘secret speech’, ‘de-Stalinization’ and the Soviet invasion of Hungary in 1956 engendered a growing plurality of perspectives on the European left, and it was under these new conditions that the British left increasingly questioned Stalinist orthodoxies, and established critiques of labourism and the ‘British Road to Socialism’. The search for alternatives to the classical Marxist, social democratic and Soviet canons led to a new theoretical heterodoxy, bringing Gramscian and world-systems theories to the fore along with a more politically ambiguous conception of the ‘national question’. This chapter integrates an analysis of the intellectual development of left-wing Scottish nationalism with a consideration of the growth of its influence within the labour movement during the 1960s and 1970s.

This article uses Frank Moorhouse as a study of the formation of a public intellectual in the 1960s and 1970s. Moorhouse was a key figure in the Sydney Push, a loose Libertarian-anarchist network of artists, writers, intellectuals and party people who rejected the dominant moral values of the 1950s and 1960s. A journalist, Moorhouse later became a well-known fiction writer who was part of a similarly bohemian and activist milieu centred in Sydney's Balmain. Taking Frank Moorhouse as a case study, I will argue that there is something particular about the way public intellectuals have historically been formed and given voice in Australian life, which is characterised by a permeability between art and writing practices and between academic and activist milieux.

ABSTRACTThis article examines comedian Richard Claxton “Dick” Gregory's comical articulation of religious belief and belonging through his speeches and religious writings during the 1960s and 1970s. It argues that, during his most visible public presence as an activist and comedic entertainer, Gregory bore an irreverent scriptural authority for his readers and comedy audiences who sought a prominent, public affirmation of their suspicion and criticism of religious authorities and conventional religious teachings. This suspicion would allow them to grapple with the oppressive presence of religion in the long history of Western colonialism, in the U.S. context of slavery, and in the violence and segregation of Jim Crow America. Following this religious suspicion, however, Gregory's consistent goal was to implement just social teachings stemming from socially and theologically progressive readings of the Hebrew Bible and of the teachings of Jesus in the Gospels. Gregory's irreverence modeled, and reflected, the maintenance of belief in both the divine and in the justness of remaking an oppressive, violent, unequal world through nonviolent activism in accordance with his understanding of the teachings of the King James scriptures that he read throughout his life. This study of comedy uses one African American male's production of irreverent, authoritative religious rhetoric to display a noteworthy mode of mid-century African American religious liberalism. It is also a case study highlighting the complexity of religious belief and affiliation. Despite acknowledged ambivalences about his commitments to religion, Gregory also modeled ways for audiences to reframe religious commitments to produce social change.

PurposeThis paper examines architecture as an example of the evolving context of qualifying routes in UK professions.Design/methodology/approachThe background and current state of architectural education, qualifying routes and regulatory frameworks in the UK is presented as a case-study, and compared with practices in professional education and qualifying more generally including the use of Degree Apprenticeships.FindingsArchitecture has since the 1960s maintained an entry-route that is premised on periods of full-time academic study plus full-time practice. While a minority part-time version of this route has always existed (and is now being expanded through Degree Apprenticeships), variations seen in other professions such as experienced practitioner entry and accelerated routes from cognate fields have so far been lacking. Pressures for reform are emerging both from external changes affecting the profession and from the high cost of qualifying in relation to median incomes in the sector.Practical implicationsThere is a need for more flexible and less expensive routes to qualifying as an architect, with substantial scope to use practices from other professions and areas of higher education to recognise existing levels of competence and improve crossover with other design and construction fields.Originality/valueThis is the first review of architectural qualifying requirements that has been made in the context of professional entry more generally.

In this article, we examine heavy industrialization and second tier urbanization in South Korea during the 1970s from a geopolitical economic perspective. We highlight the crucial, spatially complex geopolitical process of forming transnational class alliances, embedded in Cold War geopolitics, which has been neglected within state-centric developmental state theories and approaches to urbanization. Specifically, we trace the changes in the state’s original developmental plan for promoting the machinery industry in the southeast region during the 1960s and 1970s. We show how Hyundai, one of the most dominant chaebols, grew to exercise decisive influence over the state’s developmental strategy and became a powerhouse in the Korean economy, particularly in the city of Ulsan. Based on a case study of the Four Core Plants Plan, we show that the success of Hyundai was not an outcome of the effectiveness of the state’s developmental policy but was, ironically, due to the failure of the government’s original plan. The successful substitution of Hyundai’s own strategy for the state’s plan, which contributed enormously to the growth of Ulsan, would have been impossible without Hyundai’s enrollment into the transnational geopolitical economic alliance spurred by US military projects in Asia.

This chapter traces Foucauldian technologies of power in the James Bond universe and characterises the Bond franchise’s biopolitics in the cultural environment of the 1960s and 1970s, when 007 became a mass phenomenon. The majority of the chapter is dedicated to a case study of On Her Majesty’s Secret Service, Ian Fleming’s tenth Bond novel (1963) and the sixth film in the EON series (1969). The chapter highlights the intersection between reproduction and fertility on the one hand and the infliction of death and mass genocide on the other, and it examines how James Bond juxtaposes the disciplinary means that are directed against the body (as an organism) on the one hand, and the state-powered regulation of biological processes that control the population on the other. The two versions of On Her Majesty’s Secret Service amount to the franchise’s most straightforward foray into the realm of biopolitics and would pave the way for the franchise’s subsequent biopolitical and eugenic moments, like when the figure of the genocidal villain gets to articulate the franchise’s own subliminal agenda regarding population control and the future of the (British) species.
