Abstract
The paper deals with the design of azimuthal cuts on a conducting cylinder. It analyses the effect of various cut shapes in minimising the stray magnetic field in the cut region, when an orthogonal magnetic field is penetrating through the cylinder. Both an analytical model and a finite element code are used for the analyses in the time and frequency domain. Results from both methods are compared and a fairly good agreement is found. The non‐linearly tapered cut results as the best solution for minimising the stray field.

Abstract
Purpose
This paper aims to present the first systematic review of the literature relating to the relationships between organisations and their marketing agencies, the agency–client relationship, and presents a concept matrix that identifies the key areas of investigation, and topics where further research would be beneficial. As agencies play a pivotal role in operationalising marketing strategy, this relationship is central to marketing theory, management and practice.
Design/methodology/approach
A systematic review of the literature was performed using key databases and search terms, and filtering on the basis of criteria relating, for example, to relevance and format, to create a core set of refereed papers on the agency–client relationship in the marketing and advertising domains. Bibliographic and thematic analysis was used to profile the literature in the dataset, and to draw out key themes.
Findings
The paper provides an analysis of the extant knowledge base, including key themes, journals and research methods. The following themes emerged from the literature, and are used to elaborate further on the existing body of knowledge: conflict, client account management, contracts and agency theory, cultural and international perspectives and co-creation. An agenda for future research is proposed that advocates a focus on theoretical foundations, research strategies and research topics and themes.
Originality/value
This is the first systematic review of the literature on agency–client relationships, which is scattered across disciplines and informed by several theoretical perspectives. Given the increasing complexity of agency–client relationships in the digital age, and increasing need to understand “marketing-as-practice”, the coherent overview offered by this paper is of particular value for guiding future research.

Abstract
An analytical model, based on Fourier expansion of the eddy current components on a cylindrical shell, which was already developed and tested on a fusion device, has been further improved. It now allows for the analysis of the effects of azimuthal gaps when the shell reacts to a forcing field with any azimuthal and axial harmonic content, provided that the field is antimetric with respect to the equatorial plane. The model results have been validated with experimental tests on the RFX shell.

Abstract
Purpose
Renal failure is an end-stage consequence after persistent hyperglycemia during diabetic nephropathy (DN), and the etiology of DN has been linked to oxidative stress. The purpose of this research was to determine the beneficial synergistic effects of S-Allyl Cysteine (SAC) and Taurine (TAU) on oxidative damage in the kidneys of type 2 diabetic rats induced by hyperglycemia.
Design/methodology/approach
Experimental diabetes was developed by administering intraperitoneal single dose of streptozotocin (STZ; 65 mg/kg) with nicotinamide (NA; 230 mg/kg) in adult rats. Diabetic and control rats were treated with SAC (150 mg/kg), TAU (200 mg/kg) or SAC and TAU combination (75 + 100 mg/kg) for four weeks. The estimation of body weight, fasting blood glucose (FBG), oral glucose tolerance test (OGTT), oxidative stress markers along with kidney histopathology was done to investigate the antidiabetic potential of SAC/TAU in the NA/STZ diabetic group.
Findings
The following results were obtained for the therapeutic efficacy of SAC/TAU: decrease in blood glucose level, decreased level of thiobarbituric acid reactive substances (TBARS) and increased levels of GSH, glutathione-s-transferase (GST) and catalase (CAT). SAC/TAU significantly modulated diabetes-induced histological changes in the kidney of rats.
Originality/value
SAC/TAU combination therapy modulated the oxidative stress markers in the kidney in diabetic rat model and also prevented oxidative damage as observed through histopathological findings.

Abstract
Purpose
This paper aims to explore three operations and supply chain management (OSCM) approaches for meeting the 2 °C targets to counteract climate change: adaptation (adjusting to climatic impacts); mitigation (innovating towards low-carbon practices); and carbon-removing negative emissions technologies (NETs). We suggest that adaptation nor mitigation may be enough to meet the current climate targets, thus calling for NETs, resulting in the following question: How can operations and supply chains be reconceptualized for NETs?
Design/methodology/approach
We draw on the sustainable supply chain and transitions discourses along with interview data involving 125 experts gathered from a broad research project focused on geoengineering and NETs. We analyze three case studies of emerging NETs (biochar, direct air carbon capture and storage and ocean alkalinity enhancement), leading to propositions on the link between OSCM and NETs.
Findings
Although some NETs are promising, there remains considerable variance and uncertainty over supply chain configurations, efficacy, social acceptability and potential risks of unintended detrimental consequences. We introduce the concept of transformative OSCM, which encompasses policy interventions to foster the emergence of new technologies in industry sectors driven by social mandates but lack clear commercial incentives.
Originality/value
To the best of the authors’ knowledge, this paper is among the first that studies NETs from an OSCM perspective. It suggests a pathway toward new industry structures and policy support to effectively tackle climate change through carbon removal.

Abstract
A translation framework and associated processes and activities for bridging the research-to-practice gap in early childhood intervention are described. Translational processes and activities include methods and procedures for identifying evidence-based practices, translating findings from research evidence into early childhood intervention procedures, and promoting practitioners’ and parents’ routine use of the practices. The framework includes four interrelated processes and activities. Type 1 translation uses research findings to develop evidence-based practices. Type 2 translation involves the use of evidence-based professional development (implementation) practices to promote practitioners’ and parents’ use of evidence-based early childhood intervention practices. Type 3 translation includes activities to evaluate whether the use of evidence-based practices as part of routine early intervention have expected benefits and outcomes. Type 4 translation includes activities for the dissemination, diffusion, and promotion of broad-based adoption and use of evidence-based practices. Examples of each type of translation are described as are implications for practice.

Abstract
Purpose
The substantial growth in literature on knowledge-intensive business services (KIBSs) has thrown light on their contributions to innovation and innovation systems. This paper is the first of a set that examines major debates and conclusions to have emerged from this growing body of evidence.
Design/methodology/approach
This is a review essay, which also presents relevant statistics. It addresses definitional issues and controversies, and sets out basic trends and characteristics of the KIBS industries. The focus is mainly on KIBS firms, though the production of similar services in other types of organisation is also considered.
Findings
Many of the conclusions of an earlier (2005) review in this journal remain valid, though difficulties in capturing these activities in official statistics mean that there are many issues that demand closer inspection. Understanding the role and future prospects of KIBS will also require looking beyond the literature that focuses just on KIBS industries.
Research limitations/implications
This study involves literature review and statistical analysis. Future work would benefit from involvement of practitioners and users of KIBS.
Practical implications
More explicit consideration of KIBS in statistical frameworks is still required, and novel approaches to data conceptualisation and production should be explored.
Originality/value
The growing literature on KIBS, and its implications for understanding the roles and future development of the firms and their relationships to innovation systems, requires systematic analysis. Available statistics have been brought together, and this paper also reflects critically on the trajectories of research on these topics.

Abstract
Purpose
This paper aims to report on a pilot research project designed to explore if new mobile augmented reality (AR) technologies have the potential to enhance the learning of clinical skills in the lab.
Design/methodology/approach
An exploratory action-research-based pilot study was undertaken to explore an initial proof-of-concept design in using AR resources to supplement clinical skills lab teaching. A convenience non-probability sample of 72 undergraduate nursing students tested these resources during lab sessions, and participated in post-exposure surveys and focus groups to help evaluate them. This pilot design aimed to test logistics and gather information prior to further developmental work.
Findings
Key similarities emerged between the survey and focus group findings regarding the technical issues and support for student learning. Students clearly expressed a comfort with the technology, and both students and faculty identified the ability to access resources to support self-directed learning and review of skills as positive attributes of using AR. However, technical issues such as slow response times and incompatible smartphones interfered with resource access and frustrated some students, potentially having a negative impact on their learning. Students gave positive feedback regarding the value of mobile access and having AR resources available “at the bedside” where they were practicing.
Research limitations/implications
This empirical pilot study was limited to a small number of participants in a single location. However, a deeper understanding of the potential value of AR in clinical health professional education, and best practices in implementing these new technologies, was achieved.
Practical implications
This study provides a valuable practical contribution, as the approach for AR resource development described can be readily replicated by teachers with limited technical skills. The practical limitations of AR technologies discovered by use in real-world settings will provide developers and educators with valuable information as they begin to explore the use of AR in the lab and beyond.
Social implications
AR represents a rapidly developing field, with increasing social impact. This study provides some initial ideas that will help inform future uptake of AR in wider educational settings, beyond health professional education.
Originality/value
This study represents original work in the field, and specifically, an original implementation of AR in an educational context.

Abstract
Purpose
The purpose of this paper is to identify, measure and optimise financial risk and its effect on returns from innovation projects on an accrual basis and on a cash basis in a commodity industry.
Design/methodology/approach
A hypothetical case study, based on a real case, of a petrochemical commodity industry in Brazil was analysed with commodities pricing rules based on actual contracts. Earnings at risk (EaR) and cash flow at risk (CFaR) measures were applied, as well as a metric proposed in this paper called cash balance at risk (CBaR).
Findings
The paper demonstrates that financial risk measurement and optimisation are important issues in the decision-making process in the petrochemical industry. EaR, CFaR and CBaR measures are helpful when used alongside standard procedures of project evaluation. The findings also show that innovative technologies, in certain conditions, may act as “natural hedging”. It was found that the time delay between revenues and expenses leads to financial risk exposure to changes in prices and foreign exchange rates. Projects can use financing and hedging to boost their results.
Originality/value
An innovative project was compared with an expansion project in a petrochemical industry. A model for petrochemical commodities contract pricing was added in an analysis that included financing and hedging. The findings in this paper suggest that it is important to consider financial risk measures in project evaluation.
Objetivo
O objetivo deste trabalho é identificar, medir e otimizar o risco financeiro e seus efeitos sobre os resultados de projetos com inovação, tanto na perspectiva do regime contábil quanto do regime de caixa, em uma indústria de commodities.
Abordagem
Um estudo de caso hipotético, baseado em um caso real de uma indústria petroquímica brasileira, foi analisado com regras de precificação de commodities baseados em contratos reais. As métricas Earnings at Risk (EaR) e Cash Flow at Risk (CFaR) foram utilizadas, assim como uma métrica proposta neste trabalho, denominada Cash Balance at Risk (CBaR).
Resultados
Este artigo demonstrou que a mensuração e otimização do risco financeiro são questões importantes no processo de tomada de decisão em uma indústria petroquímica. As medidas EaR, CFaR e CBaR se apresentaram como contribuições ao processo padrão de avaliação de projetos. Os resultados também demonstraram que inovações tecnológicas, em certas condições, podem funcionar como um “hedge natural”. Foi verificado que descasamentos temporais entre recebimentos e despesas geram uma exposição financeira a oscilações em preços e em valores de moedas estrangeiras. Financiamento e hedge podem ser utilizados em conjunto para aprimorar resultados de projetos.
Originalidade/valor
Um projeto com inovação foi comparado com um projeto de expansão em uma indústria petroquímica. Foi realizada uma analise de risco que agrega ao financiamento e ao hedge o uso de contratos de precificação de commodities. Os resultados desse projeto demonstram que é importante considerar medidas de risco financeiro nas avaliações de projetos.

Abstract
Purpose
Energy commodities are characterised by rigid demand and high price volatility, linked to many variables such as climate factors, exchange rates, availability of resources. At the same time, the authorities often set prices, so wholesale energy companies need to create margins carefully by managing the procurement process and selecting appropriate tools to manage the risks associated with the volatility of energy prices. The purpose of this paper is to analyse and evaluate price and volume risks in the energy procurement process considering a “non-speculative” point of view, which is understudied in the literature review.
Design/methodology/approach
The paper adopts a quantitative approach to risk evaluation, based on accounting indicators, and applies it to a large Italian energy wholesale company.
Findings
A set of key risk indicators to measure price and volume risks is presented in the results, split into synthesis risk, unbalanced risks, modulation risks and risks derived from bilateral contracts. These indicators are applied to the case study, and each risk is prioritised and discussed.
Originality/value
This contribution is one of the first attempts to analyse energy procurement risks in a non-speculative approach. The proposed method allows: first, to evaluate and prioritise the three major types in the energy procurement process, second, to observe the trend of risk exposure, third, the performance measurement of the procurement process, and fourth, benchmarking activities if widely implemented in the energy sector.
