The need for guidance in setting reliability requirements for military equipment is explored and the conclusions of a study into the feasibility of constructing a reliability cost model are summarised. A suite of three reliability cost models is described together with the results of example applications.

The purpose of this paper is the investigation of the main aspects of optimal reliability allocation with respect to the design of hybrid electric vehicles. In particular, with reference to the hybrid electric vehicle propulsion system, the problem of data uncertainty, due to a scarce knowledge of the components' reliabilities, is taken into account. This problem is crucial for new technology systems and it is faced with a Bayesian approach: components' reliabilities are considered as random variables, characterised in the paper by negative log‐gamma distributions.

The main aspects of optimal reliability allocation with the design of hybrid electric vehicles are presented, pointing out the opportunity of a reliability evaluation in the planning stage.

The topic of a series hybrid vehicle reliability is addressed, nevertheless results can be easily extended to the parallel configuration. In particular, the opportunity of a reliability evaluation of the propulsion system in the design stage is highlighted, mainly when new technology components are involved.

The value of the paper consists in the methodology allowing to express the system reliability uncertainty as a function of component uncertain data. Then, as far as concern the practical implications, the optimal allocation of the components' reliabilities can be efficiently performed, in order to minimise the system total cost respecting a prefixed value of the system reliability. In the final part of the paper, a numerical application, related to a series hybrid electric vehicle propulsion system, is presented to show the feasibility of the approach.

This chapter provides a presentation about Chapter 1 of The Balance of the National Economy, 1923–24, edited by Pavel Illich Popov. The Balance was issued in June 1926 by the Central Statistical Administration (CSU or TsSU) of the USSR, which Popov had headed from July 1918 to January 1926. In the first part of our chapter, we show how Popov’s work on the balance of the national economy was rooted in the specific scientific and political culture of zemstvo statisticians inherited from the Tsar. Statistical inquiry was considered an objective scientific process based on international standards. Furthermore, like zemstvo statisticians, CSU statisticians developed great autonomous political power. The balance of the national economy was built according to these principles, which met harsh criticism from revolutionaries and Bolsheviks. In the second part, we analyze the contents of Popov’s Chapter 1, especially the theoretical foundations of the balance and its connection with Soviet planning. In the third part, we discuss the balance’s significance in the years 1926–1929, years which ended the NEP and launched the first Five-Year Plan, so as to understand how CSU’s balance didn’t become a standard Soviet statistical instrument and was discarded as a “bourgeois” device.

Post 9/11 events not only exposed the visible and invisible aspects of the often intertwined self‐interest of political, economic and especially religious elites, but also presented a practical and ideological vacuum susceptible to “once and for all” opportunistic fantasies of ultra and Neo‐conservative, cum religious, fanatics. The purpose of this paper is to counter balance the constant flow of Neo‐liberal and religious‐fundamentalist propaganda that is having a destructive effect on hard‐won civil ideals and democratic freedoms.

This paper presents a study of the relationship between visible and invisible power in the context of a historical study of the great age of tolerance and co‐existence between Jews, Muslims and Christians. The paper uses Benvenisti's “double history” methodology to recover what is visible on the surface and the “buried history” of what is invisible to discern the implications the Spanish Convivencia has for contemporary debates over political and religious “purity”.

This paper discovers dangerous signs of a continuing ahistorical hubris amongst elites and others that denies the historical evidence for the possibility of mutual accommodations between political and religious communities. This paper locates the need to recover lost, or discounted, multiple histories and (in)visible portents of a future other than the triumphalism of Western, especially “exceptionalist” US interests.

This paper demonstrates the need for more research into the use/misuse of historical evidence within (in)visible power mechanisms designed to serve ideological and hegemonic interests.

In our uncertain age, this paper is notable for developing a historically grounded vision of a real‐politic new world order based on mutual accommodation and respect.

The purpose of this paper is to investigate the extent of retail change in the UK grocery sector over the last 30 years.

In 1980, a press article by Richard Milner and Patience Wheatcroft attempted to anticipate retail change by 1984. Taking that as a template, the paper examines how retail did, in fact, change over a much longer timescale: with some unanticipated innovations in place even by 1984. Reference is made to academic research on grocery retailing in progress at the time and which has recently been revisited.

Although Milner and Wheatcroft tackled the modest task of looking ahead just four years, the content of their article is intriguingly reflective of the retail structure and systems of the UK at the time. Whilst some innovations were not anticipated, the broad themes of superstore power and market regulation still command attention 30 years on.

Through reconsidering 30 years of retail change, the paper highlights that with time how do you shop has come to pose at least as interesting a question as where do you shop.

The aim of this paper is to provide an overview of a novel offender personality disorder (OPD) higher education programme and the research evaluation results collected over a three-year period. Data from Phase 1 was collected from a face-to-face mode of delivery, and Phase 2 data collected from the same programme was from an online mode of delivery because of the COVID-19 pandemic.

In Phase 1, three modules were developed and delivered in a fully face-to-face format before the pandemic in 2019–2020 (n = 52 student participants). In 2020–2021 (n = 66 student participants), training was adapted into a fully online mode of delivery in Phase 2. This mixed-methods study evaluated participant confidence and compassion. Pre-, post- and six-month follow-up questionnaires were completed. Qualitative interviews were conducted across both phases to gain in-depth feedback on this programme (Phase 1: N = 7 students, Phase 2: N = 2 students, N = 5 leaders). Data from Phase 1 (face-to-face) and Phase 2 (online) are synthesised for comparison.

In Phase 1 (N = 52), confidence in working with people with personality disorder or associated difficulties improved significantly, while compassion did not change. In Phase 2 (N = 66), these results were replicated, with statistically significant improvements in confidence reported. Compassion, however, was reduced in Phase 2 at the six-month follow-up. Results have been integrated and have assisted in shaping the future of modules to meet the learning needs of students.

Further research into the impact of different modes of delivery is important for the future of education in a post-pandemic digitalised society. Comparisons of blended learning approaches were not covered but would be beneficial to explore and evaluate in the future.

This comparison provided informed learning for consideration in the development of non-related educational programmes and, hence, was of use to other educational providers.

This paper provides a comparison of a student-evaluated training programme, thus providing insights into the impact of delivering a relational-focused training programme in both face-to-face and online distance learning delivery modes. From this pedagogic research evaluation, the authors were able to derive unique insights into the outcomes of this programme.

The Howard Shuttering Contractors case throws considerable light on the importance which the tribunals attach to warnings before dismissing an employee. In this case the tribunal took great pains to interpret the intention of the parties to the different site agreements, and it came to the conclusion that the agreed procedure was not followed. One other matter, which must be particularly noted by employers, is that where a final warning is required, this final warning must be “a warning”, and not the actual dismissal. So that where, for example, three warnings are to be given, the third must be a “warning”. It is after the employee has misconducted himself thereafter that the employer may dismiss.

The purpose of this paper is to examine the complex and shifting relationship between the Anglo American Corporation (Anglo) and the South African State (“the State”) as reflected in Anglo’s annual reports.

This paper builds on research on the role of annual reports in ideological conflict. To examine the ongoing relationship between Anglo and the State, the authors read all the annual reports published by Anglo American from 1917 to 1975, looking for instances in which the corporation appeared to be attempting to address, criticise, compliment, or implore the State.

During the period under study, despite the apparent struggles between the South African State and Anglo American, the relationship between the two was primarily symbiotic. The symbolic confrontation engaged in by these two behemoths perpetuated the real, physical violence perpetrated on the oppressed workers. By appearing to be a liberal opponent of apartheid, Anglo was able to ensure continued investment in South Africa.

The examination of decades’ worth of annual reports provides an example of how these supposedly neutral instruments were used to contest and sustain power. Thereby, Anglo could continue to exploit workers, reap enormous profits, and maintain a fiction of opposition to the oppressive State. The State also benefited from its support of Anglo, which provided a plurality of tax revenue and economic expansion during the period.

This paper provides insights into the ways the State and other institutions sustain each other in the pursuit of economic and political power in the face of visible and widely condemned injustices. Although they frequently contested each other’s primacy, both benefited while black South African miners suffered.
