This study aims to ascertain the personal characteristics of a group of successful academic entrepreneurs in a South African university enterprise and the prevalent barriers and enablers to their entrepreneurial endeavour.

The authors used a Delphi process to identify and rank the characteristics, enablers, barriers and behaviours of entrepreneurial academics, with a Nominal Group Technique applied to establish challenges they encounter managing their enterprise and to propose solutions.

Perseverance, resilience and innovation are critical personal characteristics, while collaborative networks, efficient research infrastructure and established research competence are essential for success. The university’s support for entrepreneurship is a significant enabler, with unnecessary bureaucracy and poor access to project and general enterprise funding an impediment. Successful academic entrepreneurs have strong leadership, and effective management and communication skills.

The main limitation is the small study participant group drawn from a single university enterprise, which complicates generalisability. The study supported the use of Krueger’s (2009) entrepreneurial intentions model for low- and middle-income country (LMIC) academic entrepreneur investigation but proposed the inclusion of mitigators to entrepreneurial activation to recognise contextual deficiencies and challenges.

Skills-deficient LMIC universities should extensively and directly support their entrepreneurial academics to overcome their contextual deficiencies and challenging environment.

This study contributes to addressing the paucity of academic entrepreneur research in LMIC contexts by identifying LMIC-specific factors that inhibit the entrepreneur’s movement from entrepreneurial intention to entrepreneurial action.

The Presidential Address to the Liverpool Engineering Society by Mr. Farthing (the salient points of which are reproduced in this issue) has particular bearing upon lubrication and especially on young lubrication engineers. Mr. Farthing stressed the very wide field open to young engineers and the difficulties associated with training in order to cover as wide a field as may be necessary. It is usually so important to gain a wide knowledge before one can specialise and this is certainly the case with lubrication engineers. One cannot begin to fully appreciate the intricacies of a lubrication system with all its accessory components lubricating and guarding, for example, a large motive power plant or rolling mill, until one has more than a mere working knowledge of the plant itself, the duties it must perform, how it performs them and the snags that arise which might be overcome by correct lubrication. In view of the fact that lubrication systems are just as important in a textile mill as in a power station or a large brick works, the almost impossible‐to‐achieve‐range of knowledge that would simplify the work of a lubrication engineer is very obvious. Fortunately, lubricating principles apply to most cases and knowing how to apply one's knowledge from basic principles is the key to success in this difficult profession.

The orientation of a rigid body is described by a position‐tensor, composed of three unit vector axes fixed in the body; rotation is effected by tensor transformations in which a rotational operator is a Cartesian matrix, formed from the co‐ordinates of the pivot axis and components of the angle of rotation; rotational sequences are represented by matrix products. Three practical applications are discussed: sequences of aircraft manoeuvres, which include composite rotations of roll and pitch, or roll, pitch and yaw, applied simultaneously; the variation of sweep, incidence and dihedral of a wing moving on any axis fixed in the aircraft; the direction of the pivot axis and the angle of rotation in the motion of a retractable undercarriage between two specified positions.

THE St. Venant theory as applied to long beams of constant cross‐section could generally be used with sufficient accuracy for the solution of the structures encountered in aircraft until the last few years. The wings of high‐speed aircraft, with smaller aspect ratios, large angles of sweep‐back, and small thickness/chord ratios, introduce a new problem. There is an extensive literature on the subject, and all the methods which have been proposed are necessarily studies of redundant systems, the degree of redundancy varying according to the accuracy required. As these solutions require that the scantlings of the structure be known in advance, it was thought interesting to establish a simple method which would determine to a good approximation the skin thicknesses required. This is based on the application of the theorem of least work, which gives exact solutions of elasticity problems so long as all the terms in the strain energy expression are taken into account.

The purpose of this article is to present a summary of recent study results on a turboelectric distributed propulsion vehicle concept named N3-X.

The turboelectric distributed propulsion system uses multiple electric motor-driven propulsors that are distributed on an aircraft. The power to drive these electric propulsors is generated by separately located gas turbine-driven electric generators on the airframe. To estimate the benefits associated with this new propulsion concept, a system analysis was performed on a hybrid-wing-body transport configuration to determine fuel burn (or energy usage), community noise and emissions reductions.

N3-X would be able to reduce energy consumption by 70-72 per cent compared to a reference vehicle, a Boeing 777-200LR, flying the same mission. Predictions for landing and take-off NO_X are estimated to be 85 per cent less than the Tier 6-CAEP/6 standard. Two variants of the N3-X vehicle were examined for certification noise and found to have International Civil Aviation Organization Chapter 4 cumulative margins of 32EPNdB and 64EPNdB.

It is expected that the turboelectric distributed propulsion system may indeed provide unprecedented reductions in fuel/energy consumption, community noise and landing and take-off NO_X emissions required in future transport aircraft.

The studied propulsion concept is a step change from the conventional propulsion system and addresses growing aviation demands and concerns on the environment and energy usage.

The purpose of the paper is to explore and analyse the history of the predominantly Malaysian Network of Overseas Students Collectives in Australia (NOSCA), that existed from 1985–1994.

The paper is based on extensive archival research in the State Library of New South Wales, the National Library of Australia and the University of New South Wales (UNSW) Archives. It makes particular use of the UNSW student newspaper Tharunka and the NOSCA publications Truganini and Default. It also draws upon nine oral history interviews with former members of NOSCA.

The NOSCA was particularly prominent at the UNSW, building a base there and engaging substantially in the student union. Informed by anarchism, its activists were interested in an array of issues–especially opposition to student fees and in solidarity with struggles for democracy and national liberation in Southeast Asia, especially around East Timor. Moreover, the group would serve as a training ground for a layer of activists, dissidents and opposition politicians throughout Southeast Asia, with a milieu of ex-NOSCA figures sometimes disparagingly referred to as “the NOSCA Mafia.”

While there has been much research on overseas students, there has been far less on overseas students as protestors and activists. This paper is the first case study to specifically hone in on NOSCA, one of the most substantial and left wing overseas student groups. Tracing the group's history helps us to reframe and rethink the landscape of student activism in Australia, as less white, less middle class and less privileged.

In 1930s Britain, tennis champion Fred Perry was a household name. However, the name Fred Perry is more commonly associated with striped-collar polo shirts featuring a laurel wreath logo. In the late 1960s, Fred Perry polo shirts were standard mod and Skinhead dress. When worn by working-class youth the shirt became subversive commentary on English elitism because it had originally been designed for the tennis courts. Many punks also aligned with the brand in dual demonstration of association with working-class ethics as well as an alternative to t-shirts. In the 1980s and onward, this sartorial style was appropriated by right-wing white nationalists, which stripped it of its subcultural spirit. Patriot groups, such as neo-Nazis and the alt-right have continued to co-opt the subcultural style, simultaneously turning the Fred Perry polo into a symbol of racism and bigotry. The multi-use of the Fred Perry brand creates a challenge in how to interpret visual cues when one garment has competing perceptions that at times can be completely opposing. This study examines the history of the Fred Perry brand through the lens of symbolic interactionism, specifically how the shirt evolved from a rather innocuous, yet subversive, form of merchandize repurposed from the tennis world to youth subcultures where the polo communicated group identity. As the brand has moved through fashion cycles, the association of the Fred Perry polo with deviant groups has reduced the brand to representations of hate and separation, which has impacted sales and brand image with its intended consumers.

The purpose of this paper is to examine how the emergent 3D interactive media technologies are used as a viable tool for enhancing visitors’ overall experiences at an exhibition entitled, 300 Years of Hakka Kungfu – Digital Vision of Its Legacy and Future (Hakka Kungfu Exhibition) – presented and co-organized by the Intangible Cultural Heritage Office of Hong Kong, International Guoshu Association and the School of Creative Media, City University of Hong Kong.

A questionnaire survey in both online and paper-based formats was used for identifying visitors’ experiences in the interactions with the multimedia technologies. For this research study, a questionnaire, consisting of 26 items, was set out to measure the visitors’ experiences at the Exhibition. Since the Exhibition was about presenting a centuries-old Chinese cultural heritage, Hakka Kungfu via the use multimedia technologies, in the context of establishing a dialogue between the past and present, the researchers included questionnaire items that were devoted to enquire about the level of understanding, knowledge and enjoyment, and visitors’ new knowledge about Hong Kong history and culture was successfully disseminated to the respondents at the end of the questionnaire.

A total of 209 completed questionnaires were collected at this Hakka Kungfu Exhibition. The findings reveal that the exhibits did attract people at all ages. This Exhibition gave the visitors a sense of interest and wonder in the object and information presented in the Exhibition. Findings of this study also reveal that this Exhibition has successfully attracted a large number of female visitors, as well as visitors who have never taken any martial arts training. In addition, visitors’ Exhibition experience was found to be memorable, as well as enjoyable. Furthermore, visitors’ experience within the Exhibition suggested that it was entertaining, as well as educational. By creating a long-lasting impact on the minds of these Exhibition visitors about the connections between and relevance of traditional Chinese Kungfu, their collective cultural identity, as well as the contemporary society we live in. The Exhibition exemplified the successful integration of the presentation of Kungfu as a form of cultural heritage with engagement-creating technology, in which technology is unobtrusive but effective.

Although it is already a global trend for the museums to integrate multimedia technologies into their exhibitions, research on the situation and feedback of multimedia technology used in the museum exhibitions in Hong Kong is scarce as well as scattered. Findings of this study could help identify various factors involved in audience participation, thereby exploring the possibility of building a contact point/space for traditional Chinese Kungfu as an intangible cultural heritage, via the integration of the latest media technologies. In particular, the development of multimedia technologies has become increasingly important to museums, and museum professionals have been exploring how digital and communication technologies can be developed to offer visitors a more interactive, personalized museum experience. In general, despite the growing interest in deploying digital technology as interpretation devices in museums and galleries, there are relatively few studies that examine how visitors, both alone and with others, use new technologies when exploring the museum contents.

The author explores questions of authenticity in the media industry by showing how right-wing media figures look to present their views as authentic by defining themselves as citizen journalists and positioning themselves in opposition to mainstream media. Looking at two case studies from the United States, Andrew Breitbart and Mike Cernovich, the author shows how the language of citizen journalism (amateurism, independence, immediacy) is co-opted by such figures to appeal to increasingly distrustful and antagonistic conservative media audiences.
