The Symposium on “The Legacy of Ludwig Lachmann: Interdisciplinary Perspectives on Institutions, Agency and Uncertainty” stood out also because of a plenary session organized as a roundtable discussion on “Reminiscences of Lachmann” with the participation of Martin Fransman, Peter Lewin, Jochen Runde and Christopher Torr, and Giampaolo Garzarelli as moderator. The text that follows reports the interesting views about Lachmann’s public as well as private persona that emerged from the roundtable.

The Austrian economist Ludwig Lachmann claimed that Keynes was a lifelong subjectivist. To evaluate this, we start by distinguishing Keynes’ writings on probability theory from his writings on economics. In the General Theory (1936), Keynes’ treatment of expectations provides the basis for Lachmann’s view that Keynes was a subjectivist at heart. In his Treatise on Probability (1921), Keynes refers explicitly to the subjectivism–objectivism divide in probability theory and pins his colors to the objectivist mast. In this essay, we present the objectivist slant in Keynes’ earlier writings on probability theory. Thereafter, we evaluate the criteria Lachmann employed to cast Keynes as a subjectivist.

The learning outcomes are as follows: to understand how technology can be used to create innovative entrepreneurial opportunities; to develop analytical and critical thinking skills to understand organisations, industries and their dynamics; to analyse strategic options for an entrepreneurial organisations and motivate a proposed strategic direction; and to assess the inter-functional requirements for an entrepreneurship to successfully implement a strategy.

UCOOK, a successful emerging economy SME, is confronted with the threat of retail giants (e.g. Checkers and Woolworths) entering the meal kit space. No longer the only “new kid on the block”, UCOOK has to consider a sustainable growth strategy to remain competitive. The case provides the reader with a snapshot of experiences of a meal kit entrepreneurial venture and what it entails for them to grow in the South African milieu. Principally, this case is designed to impart knowledge and stimulate a practical understanding of entrepreneurship and strategic decision-making in the meal kit industry. Additionally, the purpose is to serve as inspiration for business students to see the opportunities that lie within strategically astute emerging market ventures.

The primary target audience for this teaching case is postgraduate business students, especially students of entrepreneurship, strategy and e-commerce. This teaching case is intended to be used as case study in post graduate business programmes such as Master of Business Administration (MBA), a specialist Masters programme such as MM (Entrepreneurship), post-graduate diploma in management (PGDip), as well as selected executive education programmes.

For many applications, including space applications, the usability and performance of a component is dependent on the surface topology of the additively manufactured part. The purpose of this paper is to present an investigation into minimizing the residual surface roughness of direct metal laser sintering (DMLS) samples by manipulating the input process parameters.

First, the ability to manipulate surface roughness by modifying processing parameters was explored. Next, the surface topography was characterized to quantify roughness. Finally, microthruster nozzles were created both additively and conventionally for flow testing and comparison.

Surface roughness of DMLS samples was found to be highly dependent on the laser power and scan speed. Because of unintended partially sintered particles adhering to the surface, a localized laser fluence mechanism was explored. Experimental results show that surface roughness is influenced by the varied parameters but is not a completely fluence driven process; therefore, a relationship between laser fluence and surface roughness can be incorporated but not completely assumed.

This paper serves as an aid in understanding the importance of surface roughness and the mechanisms associated with DMLS. Rather than exploring a more common global energy density, a localized laser fluence was initiated. Moreover, the methodology and conclusions can be used when optimizing parts via metal additive manufacturing.

Alan Hobby has recently been appointed Applications Engineer at DEK Printing Machines Ltd, Weymouth. In 1968 he joined Ferranti at Bracknell and became one of the small team setting up the thick film production unit. Four years later he joined EMI at Hayes as the Production Engineer, where he gained experience in the manufacture of high volume but relatively simple hybrids. In 1975 Alan moved to Marconi Electronic Devices Ltd at Portsmouth, where he was one of the engineers responsible for the company's programme of qualification as a hybrid manufacturer for the European Space Agency and for their BS 9450 approval programme. Since then he has been concerned with the development of printing and firing techniques both at Portsmouth and at Marconi's high volume production unit at Swindon.

This article explores an incident that raises questions relating to the making and unmaking of history, heritage and social memory. It also points to the role of the historian in unravelling forgotten pasts. On 21 May 1945, at the Royal Australian Engineers Training Camp (RAETC) Kapooka near the provincial New South Wales city of Wagga Wagga, twenty‐four ‘sappers’ or engineers, and their two ‘other ranks’ trainers, were killed in a demolitions training exercise gone terribly wrong. The accident remains the largest in Australian army history. However, following a brief flurry of national grief public memory of the tragedy soon slipped into historical obscurity. The article narrates the Kapooka story and then reflects on its role as an exemplar of how a society makes, unmakes or forgets its past.

Food—national dietary standards—is a sensitive index of socio‐economic conditions generally; there are others, reflecting different aspects, but none more sensitive. A country that eats well has healthy, robust people; the housewife who cooks hearty, nourishing meals has a lusty, virile family. It is not surprising, therefore, that all governments of the world have a food policy, ranking high in its priorities and are usually prepared to sacrifice other national policies to preserve it. Before the last war, when food was much less of an instrument of government policy than now—there were not the shortages or the price vagaries—in France, any government, whatever its colour, which could not keep down the price of food so that the poor man ate his fill, never survived long; it was—to make use of the call sign of those untidy, shambling columns from our streets which seem to monopolize the television news screens—“out!” Lovers of the Old France would say that the country had been without stable government since 1870, but the explanation for the many changes in power in France in those pre‐war days could be expressed in one word—food!

Until recently liquid chromatography has been a somewhat neglected branch of science. However, the availability of precision equipment, and even complete instruments, has made possible liquid chromatography separations of a more advanced nature. For example, suitable detectors have been developed, and pumps are available which deliver accurate volumes of solvent under pressure.

The purpose of this paper is to propose a pressure-, temperature- and acceleration-sensitive structure-integrated inductor-capacitor (LC) resonant ceramic sensor to fulfill the measurement of multi-parameters, such as the measurement of pressure, temperature and acceleration, simultaneously in automotive, aerospace and aeronautics industries.

The ceramic-based multi-parameter sensor was composed of three LC tanks, which have their resonant frequencies sensitive to pressure, temperature and acceleration separately. Two aspects from the specific sensitive structure design to the multiple signals reading technology are considered in designing the multi-parameter ceramic sensor. Theoretical analysis and ANSYS simulation are used in designing the sensitive structure, and MATLAB simulation and experiment are conducted to verify the feasibility of non-coverage of multi-readout signals.

It is found that if the parameters of sensitive structure and layout of the LC tanks integrated into the sensor are proper, the implementation of a multi-parameter sensor could be feasible.

The ceramic sensor proposed in the paper can measure pressure, temperature and acceleration simultaneously in harsh environments.

The paper creatively proposes a pressure-, temperature- and acceleration-sensitive structure-integrated LC resonant ceramic sensor for harsh environments and verifies the feasibility of the sensor from sensitive structure design to multiple-signal reading.
