Abstract
Purpose
The comparison of large volumes of complex data resulting from numerical modelling in computational electromagnetics is a demanding task, especially when validating the performance of numerical models against experimental results and testing experimental repeatability. “By‐eye” comparisons can lead to inconsistencies and inherent subjectivity. This paper establishes a “visual” benchmark by which comparisons can be made and therefore used to assist in the development of an algorithmic approach to data comparison.
Design/methodology/approach
This new method presented here is based on the Cooper‐Harper Rating Scale, which is a test pilot's evaluation‐rating instrument. This has been modified through qualitative research. The assertion that the rating scale will leave the group mean response unaltered but will reduce the variance has been statistically tested.
Findings
The proposed rating scale provides a calibration technique by which to benchmark comparisons. The scale also reduces subjectivity by producing an overall quantitative measure of similarity. The paper concludes with an application of the rating scale to assessment of a candidate algorithmic approach against correlation.
Research limitations/implications
The research findings are based on small data sets, which is a limit imposed by the industrial environment in which this scale will be used.
Practical implications
This paper provides a tool to overcome some of the key substantial difficulties in communicating similarity or difference, namely that “similarity” and “difference” have no stand‐alone definition, there is a lack of a shared language for the comparisons and little commonality for a decision‐making framework.
Originality/value
This paper provides modellers and experimentalists in computational electromagnetics (particularly electromagnetic compatibility) with a structured approach to quantifying the quality of comparative results.

Abstract
This paper analyses a number of techniques that can be used to compare complex data sets, such as those arising from electromagnetic simulation and experimentation. The techniques assessed are: correlation, several reliability factors and feature selective validation. The study examines the performance of each technique for data comparison. The paper provides a comprehensive summary of the techniques and compares their performance and comments on their use in the validation of numerical modelling codes and model designs.

Abstract
The question has been recently raised as to how far the operation of the Sale of Food and Drugs Acts of 1875, 1879, and 1899, and the Margarine Act, 1887, is affected by the Act 29 Charles II., cap. 7, “for the better observation of the Lord's Day, commonly called Sunday.” At first sight it would seem a palpable absurdity to suppose that a man could escape the penalties of one offence because he has committed another breach of the law at the same time, and in this respect law and common‐sense are, broadly speaking, in agreement; yet there are one or two cases in which at least some show of argument can be brought forward in favour of the opposite contention.

Abstract
Long before calories and joules were used to indicate energy values in relation to food, popular belief had it that some foods could increase man's output of labour, his physical strength and endurance, even his fertility. The nature of the foods varied over the years. From earliest times, flesh foods have inspired men to “gird their loins” and “put on armour”, but too long at the feasting tables produced sloth of body and spirit. Hunger sharpens the wit, which makes one wonder if that oft‐quoted statement of poverty and hunger before the Great War—“children too hungry learn”—was quite true; it is now so long ago for most of us to remember. Thetruism “An army marches on its stomach” related to food in general and relating feats of strength to individual foods is something more difficult to prove. The brawny Scot owes little to his porridge; the toiling Irish labourer moves mountains of earth, not from the beef steaks he claims to consume, but for the size of the pay‐packet at the end of the week!

Abstract
Reports on the role of UK emigrants to the USA in the creation and early development of its public accountancy profession. Explains findings in the context of US public accountancy firms founded by UK immigrants and focuses on the recruitment of qualified and unqualified public accountants from the UK. The study is based on searches of relevant archives in the UK and USA. The evidence reveals UK immigrants played a substantial part in the formation and early development of both public accountancy firms and institutions in the USA. However, the recruitment of immigrants by US firms appears to have been a temporary phenomenon pending the supply of US‐born accountants with suitable training and experience. The firms examined include local and national firms. Subject to data retrieval limitations, a major conclusion of the study is that unqualified immigrants played significant roles in the early histories of firms and institutions of US public accountancy.

Abstract
Much of contemporary institutional theory rests on the identification of structured, coherent, and encompassing logics, and from there proceeds to examine multilevel dynamics or the relationship between logics in a field. Less research directly studies the internal properties and dynamics of logics and how they are structured over time. In this paper, we propose a method for understanding the content and organization of logics over time. We advocate for an analysis of logics that is grounded in a repertoire view of culture (Swidler, 1986; Weber, 2005). This approach involves identifying the set of cultural categories that can make up logics, and measuring empirically the dimensions that mark a cultural system as more or less logic-like. We discuss several text analytic approaches suitable for discourse data, and outline a seven-step method for describing the internal organization of a cultural repertoire in term of its “logic-ness.” We provide empirical illustrations from a historical analysis of the field of alternative livestock agriculture. Our approach provides an integrated theoretical and methodological framework for the analysis of logics across a range of settings.

Abstract
Purpose
The transition to a low carbon future is an emerging challenge and requires the planning and designing of sustainable energy landscapes – landscapes that provide renewable energy while safeguarding the supply of other ecosystem services. The aim of this paper is to present the application of an ecosystem services trade-off assessment in the development of sustainable energy landscapes for long-term strategic planning in a case study in Schouwen-Duivenland, The Netherlands.
Design/methodology/approach
The application consists in three activities: in (1) stakeholder mapping hot spots of ecosystem services and renewable energy technologies in a workshop, (2) landscape design principles being discussed by a focus group, (3) experts gathering the information and proceeding with an assessment of the potential synergies and trade-offs.
Findings
The case study indicates that (1) deploying the ecosystem services framework in planning and design can enhance the development of sustainable energy landscapes, (2) diversified and accurate spatial reference systems advance the trade-off analysis of both regulating and cultural ecosystem services and (3) the involvement of local stakeholders can advance the trade-off analysis and, ultimately, facilitates the transition to a low-carbon future with sustainable energy landscapes.
Originality/value
The originality of this research lies in the creation of an approach for the deployment of ecosystem services in the planning and design of energy transition. This is useful to advance energy transition by enhancing research methods, by providing methods useful for planners and designers and by supporting communities pursuing energy self-sufficiency in a sustainable manner.
