Authors: Rout Amruta , Bbvl Deepak , Biswal Bibhuti B. , Mahanta Golak Bihari 
Published: May 2020

Purpose
This paper aims to propose fuzzy-regression-particle swarm optimization (PSO) based hybrid optimization approach for getting maximum weld quality in terms of weld strength and bead depth of penetration.

Design/methodology/approach
The prediction of welding quality to achieve best of it is not possible by any single optimization technique. Therefore, fuzzy technique has been applied to predict the weld quality in terms of weld strength and weld bead geometry in combination with a multi-performance characteristic index (MPCI). Then regression analysis has been applied to develop relation between the MPCI output value and the input welding process parameters. Finally, PSO method has been used to get the optimal welding condition by maximizing the MPCI value.

Findings
The predicted weld quality or the MPCI values in terms of combined weld strength and bead geometry has been found to be highly co-related with the weld process parameters. Therefore, it makes the process easy for setting of weld process parameters for achieving best weld quality, as there is no need to finding the relation for individual weld quality parameter and weld process parameters although they are co-related in a complicated manner.

Originality/value
In this paper, a new hybrid approach for predicting the weld quality in terms of both mechanical properties and weld geometry and optimizing the same has been proposed. As these parameters are highly correlated and dependent on the weld process parameters the proposed approach can effectively analyzing the ambiguity and significance of each process and performance parameter.
Optimal energy management for hybrid-electric aircraft
Authors: Pinto Leite José Pedro Soares , Voskuijl Mark 
Published: May 2020

Purpose
In recent years, increased awareness on global warming effects led to a renewed interest in all kinds of green technologies. Among them, some attention has been devoted to hybrid-electric aircraft – aircraft where the propulsion system contains power systems driven by electricity and power systems driven by hydrocarbon-based fuel. Examples of these systems include electric motors and gas turbines, respectively. Despite the fact that several research groups have tried to design such aircraft, in a way, it can actually save fuel with respect to conventional designs, the results hardly approach the required fuel savings to justify a new design. One possible path to improve these designs is to optimize the onboard energy management, in other words, when to use fuel and when to use stored electricity during a mission. The purpose of this paper is to address the topic of energy management applied to hybrid-electric aircraft, including its relevance for the conceptual design of aircraft and present a practical example of optimal energy management.

Design/methodology/approach
To address this problem the dynamic programming (DP) method for optimal control problems was used and, together with an aircraft performance model, an optimal energy management was obtained for a given aircraft flying a given trajectory.

Findings
The results show how the energy onboard a hybrid fuel-battery aircraft can be optimally managed during the mission. The optimal results were compared with non-optimal result, and small differences were found. A large sensitivity of the results to the battery charging efficiency was also found.

Originality/value
The novelty of this work comes from the application of DP for energy management to a variable weight system which includes energy recovery via a propeller.
Rating exotic price coverage in crop revenue insurance
Authors: Ramsey A. Ford , Ghosh Sujit K. , Goodwin Barry K. 
Published: May 2020

PurposeRevenue insurance is the most popular form of insurance available in the US federal crop insurance program. The majority of crop revenue policies are sold with a harvest price replacement feature that pays out on lost crop yields at the maximum of a realized or projected harvest price. The authors introduce a novel actuarial and statistical approach to rate revenue insurance policies with exotic price coverage: the payout depends on an order statistic or average of prices. The authors examine the price implications of different dependence models and demonstrate the feasibility of policies of this type.Design/methodology/approachHierarchical Archimedean copulas and vine copulas are used to model dependence between prices and yields and serial dependence of prices. The authors construct several synthetic exotic price coverage insurance policies and evaluate the impact of copula models on policies covering different types of risk.FindingsThe authors’ findings show that the price of exotic price coverage policies is sensitive to the choice of dependence model. Serial dependence varies across the growing season. It is possible to accurately price exotic coverage policies and we suggest these add-ons as a possible avenue for developing private crop insurance markets.Originality/valueThe authors apply hierarchical Archimedean copulas and vine copulas that allow for flexibility in the modeling of multivariate dependence. Unlike previous research, which has primarily considered dependence across space, the form of exotic price coverage requires modeling serial dependence in relative prices. Results are important for this segment of the agricultural insurance market: one of the main areas that insurers can develop private products around the federal program.
Consumers' knowledge discrepancy and confusion in intent to purchase farmed fish
Authors: Hoque Mohammed Ziaul , Alam Md. Nurul 
Published: May 2020

PurposeThe purpose of the paper is to examine the influence of consumers' perceived knowledge, knowledge discrepancy and confusion on the intention to purchase farmed fish (FF) via a survey design regarding perceptions, buying and consumption practices of urban households in Chittagong, Bangladesh.Design/methodology/approachThe samples of 498 households were selected from a stratified cluster from the Chittagong city and were interviewed using a structured questionnaire. The data have been analysed using exploratory factor analysis and structural equation modelling.FindingsThe results show that consumers' subjective knowledge (SK) is significant for purchase intention whereas objective knowledge (OK) is not. Again, consumers' SK, OK, knowledge discrepancy and confusion have no influence in forming consumers' attitude towards FF. However, consumers who overestimate their actual level of knowledge hold negative attitude towards FF and vice versa. Furthermore, consumers' OK affects their confusion inversely although it does not influence the purchase intention significantly.Practical implicationsIf the marketers can frame a more engaging means of communication and knowledge enhancement plan, consumers' attitude and purchase intention regarding FF will be signified.Originality/valueThis is the first study that fundamentally contributes to the scientific research in that it measures the knowledge discrepancy of consumers regarding FF. In addition, this study substantiates that low objective knowledge leads to confusing consumers at the time of purchasing. The effect of overestimating the level of knowledge as well as underestimating the level of knowledge in explaining the purchase intention of FF would be a supplementary addition.
Multi-physics analysis of a novel circular pantograph catenary system for high-speed trains

Published: May 2020

Purpose
In high-speed trains, the energy is supplied from a high voltage catenary to the vehicle via a pantograph catenary system (PCS). Carbon pantograph strips must maintain continuous contact with the wire to ensure safety and reliability. The contact is often confined to a particular spot, resulting in excessive wear due to mechanical and thermal damage, exacerbated by the presence of an electric arc and associated electrochemical corrosion. The effectiveness and reliability of the PCS impacts on the performance and safety of HSTs, especially under high-speed conditions. To alleviate some of these adverse effects, this paper aims to propose a configuration where a circular PCS replaces the currently used pantograph strips.

Design/methodology/approach
Two dynamic multi-physics models of a traditional PCS with a carbon strip and a novel PCS with a circular pantograph strip catenary system are established, and the electrical and mechanical characteristics of these two systems are compared. Moreover, a PCS experimental platform is designed to verify the validity and accuracy of the multi-physics model.

Findings
A novel circular pantograph system is proposed in this paper to alleviate some of the shortcomings of the traditional PCS. Comparing with a traditional PCS, the circular PCS exhibits superior performance in both electromagnetic and thermal aspects.

Originality/value
The paper offers a new technical solution to the PCS and develops a dedicated multi-physics model for analysis and performance prediction with the aim to improve the performance of the PCS. The new system offers numerous benefits, such as less friction heat, better heat dispersion and improved catenary-tracking performance.

Published: May 2020

PurposeThe concept of employer branding has drawn the attention of both academicians and practitioners over a decade. However, inaction, the objective of the employer brand managers were hardly tapped. Therefore, this paper aims to explore the views of HR manager on employer branding activities and its implementation.Design/methodology/approachThis study is a case research of three multinational companies in India. A semi-structured interview method has been adopted to collect the data and a content analysis technique was used for analyzing the data into identified themes.FindingsThe HR managers of the studied company were discussed with multiple activities related to employer branding practice and implementation in their workplace. The key observations and discussions from the interviews were themed after the analysis as meaningfulness and visibility, employer brand awareness and differentiator and human resource development (HRD) parameters.Research limitations/implicationsThe combined effect of branding theories and HRD practices will establish the most attractive and successful employer brand building process in place. Involving the potential and existing employees in the psychological contract formation; consistency among the internal and external communication systems; and top management approach with the brand highlighted the need for research and theory development in employment branding.Practical implicationsCommunication breakdown, strategic mismatch, long-term disconnects and sustained success are the strategic concerns that every company who believe in the idea of employer branding may face and need to well-handled.Originality/valueThe study concluded with the belief of the human resources managers from all the three organizations as stated – adopting a community based strategic approach to the organization’s brand and clear about what the employer brand stand across the employment lifecycle drives businesses into success.
Collegial governance in postwar Australian universities
Authors: Barnes Joel 
Published: May 2020

PurposeThe purpose of this paper is to outline the structures of collegial governance in Australian universities between 1945 and the “Dawkins reforms” of the late 1980s. It describes the historical contours of collegial governance in practice, the changes it underwent, and the structural limits within which it was able to operate.Design/methodology/approachThe analysis is based upon the writings of academics and university administrators from the period, with more fine-grained exemplification provided by archival and other evidence from Faculties of Arts and their equivalents in newer universities.FindingsElements of hierarchy and lateral organisation coexisted in the pre-Dawkins university in ways not generally made explicit in the existing literature. This mixture was sustained by ideals about academic freedom.Research limitations/implicationsBy historicising “collegiality” the research problematises polemical uses of the term, either for or against. It also seeks to clarify the distinctiveness of contemporary structures—especially for those with no first-hand experience of the pre-Dawkins university—by demonstrating historical difference without resort to nostalgia.Originality/value“Collegiality” is a common concept in education and organisation studies, as well as in critiques of the contemporary corporate university. However, the concept has received little sustained historical investigation. A clearer history of collegial governance is valuable both in its own right and as a conceptually clarifying resource for contemporary analyses of collegiality and managerialism.

Authors: Gyllencreutz Lina , Rådestad Monica , Saveman Britt-Inger 
Published: May 2020

PurposeThe purpose of this study was from a Swedish perspective to map experts' opinions on theoretical statements of essential collaboration activities for management of mining injury incidents.Design/methodology/approachA Delphi technique was performed, asking opinions from experts in iterative rounds to generate understanding and form consensus on group opinion around multi-agency management. The experts were personnel from emergency medical service, rescue service and mine industry, all with operative command positions.FindingsThree iterative rounds were performed. The first round was conducted as a workshop to collect opinions about the most important multi-agency collaboration activities to optimize victim's outcome from an injury incident in an underground mine. This resulted in 63 statements and additional three were added during the second round. The statements were divided into one trajectory and seventh time phases and comprised, e.g. early alarm routines, support of early life-saving interventions, relevant resources and equipment for the assignment and command and control center and functions with predefined action plans for response. It also comprised shared and communicated decisions about each agency's responsibility and safety. All statements reached consensus among the experts in Round 3.Research limitations/implicationsThe experts included in this study seem to be adequate but there could be other experts and different statements that other researchers might consider.Practical implicationsThese statements could be used to evaluate collaboration in major incidents exercises. The statements can also be quality indicators for reporting results from multi-agency management.Originality/valueThis paper contributes to the research field of collaboration and joint practices between and among personnel involved in rescue operations.

Published: May 2020

PurposeThis study aims to analyze the effect of audit findings and audit recommendations follow-up on the quality of financial reports and the quality of public services in the context of applying accrual accounting systems to local government in Indonesia. This study also examines whether the quality of the financial report affects the quality of public services.Design/methodology/approachThis study employed cross-sectional regression using data from 1,437 observations from 491 districts/cities for 2014–2016. The data illustrates the conditions prior to the adoption of the accrual accounting system (2014), the initial year of application/transition period (2015) and the second year of the expected accrual accounting system (2016).FindingsThe results of the study indicate that, in general, the quality of financial reports affects the quality of public services. Regarding the implementation of audits in the public sector, it is also found that audit findings have a negative impact on the quality of financial report and the quality of public services, while audit recommendations follow-up plays a positive role in improving the quality of financial report and the quality of public services.Research limitations/implicationsThe implication of the results of this study is closely related to the efforts to realize the ultimate goal of the recent government reforms. In order to increase the quality of public services in the era of higher report requirements through an accrual accounting system, the government should focus on the quality of financial reports, audit findings and the audit recommendations follow-up.Originality/valueThis study provides new insight on the link between the public sector auditing and the quality of accounting in accrual implementation context and the quality of public services.
Digital production innovation projects – The applicability of managerial controls under high levels of complexity and uncertainty
Authors: Johansson Sara , Kullström Malin , Björk Jennie , Karlsson Anna , Nilsson Susanne 
Published: May 2020

PurposeThe purpose of the present study is to assist academics and practitioners in supporting and managing digital production innovation projects using managerial controls. The focus is on projects that deliver innovations containing new combinations of physical, digital and/or cyber-physical components, developed to be used within a production system. More specifically, this paper aims to explore the applicability of different managerial controls for managing and supporting digital production innovation projects, i.e. projects that are characterized by high levels of complexity and uncertainty.Design/methodology/approachThis is a multiple-case study in which interview data was collected from five digital production innovation projects in two manufacturing firms. The empirical data was used to analyze success factors, challenges and obstacles in different phases of the studied projects, and to connect these to the application of different types of managerial controls.FindingsThe findings provide an increased understanding of who to control, what to control and how to control in digital production innovation projects.Research limitations/implicationsThis paper is focused specifically on the perception of managerial controls in digital production innovation projects and has not explicitly focused on manufacturing companies' intended usage of managerial controls. This paper's focus on manufacturing companies with producing customers and on projects developing solutions for their respective customers' production systems also encourages further studies at other companies undergoing a comparable transition. Given the necessary system perspective on managerial controls that is being highlighted, this paper emphasizes further research needs on how firms can also apply managerial controls to support external collaborations.Practical implicationsThe results have a number of managerial implications regarding digital production innovation projects. The most prominent findings revealed the importance of giving attention to the managerial controls related to the decision-making process and the involvement from stakeholders outside the organization itself. In particular, it was shown that managerial controls securing a more holistic involvement in the decision-making process should be applied, and that managerial controls suitable for customers and partners need to be developed.Originality/valueThe study is among the first studies to focus on the application and perceived effectiveness of managerial controls in digital production innovation projects. The ways in which managerial controls are applied to collaborations with customers and partners and the ways in which action, cultural and personnel controls are combined and aligned to support the corporate decision-making process particularly stand out as essential for manufacturing companies' Industry 4.0 transition.
Catching the wave: Industry 4.0 in BRICS
Authors: Erro-Garcés Amaya , Aranaz-Núñez Irene 
Published: May 2020

PurposeThis research aims to conduct, to the best of our knowledge, the first systematic review of the implementation of Industry 4.0 in BRICS. This review facilitates the identification of main factors that affect the readiness to adopt Industry 4.0 in BRICS and the role of different agents, such as multinationals, the public sector or educative institutions.Design/methodology/approachKey publications published from 2010 to 2019 have been analysed. A total of 61 papers have been selected from the systematic review.FindingsThree factors of convergence of BRICS to developed economies in terms of Industry 4.0 are identified: (1) the public initiatives that can also result in the attraction of talent from developed countries to BRICS; (2) the role of multinationals and (3) the implication of educational institutions.Research limitations/implicationsThis review has some limitations. First, some grey literature, such as reports from non-governmental organisations and front-line practitioners' reflections, were not included. Second, only research studies in English were reviewedPractical implicationsThe heterogeneity of BRICS amongst themselves affects the implementation of Industry 4.0 policies. Therefore, public policies should differ among countries to achieve the different readiness of companies within each country. Industry 4.0 cannot be understood as a manufacturing strategy against delocalisation, as emerging countries, such as BRICS, are also aware of the potential of automation.Originality/valueBased on a systematic review, this article shows that the strategy created by Germany to increase industrial productivity has been also introduced in BRICS countries as a critical factor to improve their competitiveness.
