Abstract
Quantitative disease resistance (QDR) is a conserved form of plant immunity that limits infections caused by a broad range of pathogens. QDR has a complex genetic determinism. The extent to which molecular components of the QDR response vary across plant species remains elusive. The fungal pathogen Sclerotinia sclerotiorum, causal agent of white mold diseases on hundreds of plant species, triggers QDR in host populations. To document the diversity of local responses to S. sclerotiorum at the molecular level, we analyzed the complete transcriptomes of six species spanning the Pentapetalae (Phaseolus vulgaris, Ricinus communis, Arabidopsis [Arabidopsis thaliana], Helianthus annuus, Solanum lycopersicum, and Beta vulgaris) inoculated with the same strain of S. sclerotiorum. About one-third of plant transcriptomes responded locally to S. sclerotiorum, including a high proportion of broadly conserved genes showing frequent regulatory divergence at the interspecific level. Evolutionary inferences suggested a trend toward the acquisition of gene induction relatively recently in several lineages. Focusing on a group of ABCG transporters, we propose that exaptation by regulatory divergence contributed to the evolution of QDR. This evolutionary scenario has implications for understanding the QDR spectrum and durability. Our work provides resources for functional studies of gene regulation and QDR molecular mechanisms across the Pentapetalae.
Institutional Contradictions of the French state as Shareholder
Authors: Girard Carine , Gates Stephen 
Published: April 2020

PurposeThis paper aims to demonstrate that state shareholders are confronted with contradictory logics leading to institutional contradictions that activist shareholders can exploit. The competing logics of the state as shareholder and their impact on corporate governance and shareholder activism offer fertile grounds for research advances in Coordinated Market Economies (CMEs).Design/methodology/approachThrough an extensive literature review of state ownership, institutional contradictions and shareholder activism, this paper analyzes two case studies involving the French State as shareholder.FindingsIn the French context, these two cases illustrate how institutional contradictions result in opportunities for shareholder activism. By focusing on the institutional contradictions of the state shareholder, this investigation suggests a need for experimental research to observe how shareholder activists adapt to each institutional change in CMEs. This experimentation can help policymakers to avoid creating additional conditions that shareholder activists can exploit.Research limitations/implicationsThis focuses only on France and its state shareholdings. To generalize results, studies of other CMEs and state shareholders are needed.Practical implicationsPolicymakers should consider all legislative proposals for their potential to deviate from corporate governance practice by experimenting with them in a laboratory setting. Shareholder activists can compare state shareholders’ actions against the state’s legislation to emphasize institutional contradictions that counter minority shareholders’ rights.Originality/valueThis research is the first to analyze how the state as shareholder can exploit its competing logics to resist against shareholder activism and support management or to become itself a shareholder activist.

Published: April 2020

PurposeFish are considered as one of the important aquatic animals in the planet. They play a vital role in the nutrient cycle. They can be considered as one of the healthy food for human beings. They can also act as a solution for some of the human health problems. If fish are affected by several diseases, they in turn provide an adverse effect on human health. Therefore, it is very much essential to protect fish from being affected by any diseases.Design/methodology/approachThis paper is mainly focused on the identification of the red spot diseased area in fish. In this work, a fuzzy rule based method (FRBAM) and triangular membership function (TMFN) is used to identify the red spot disease (RSD) in the fish by analyzing several red spot diseased fish (RSDF) images. The canny edge detector is used for intermediate processing of RSDF images.FindingsThe proposed method is able to identify the red pixels over the fish by marking the affected area with red color by using a standard RGB model.Originality/valueThe proposed method follows FRBAM and TMFN in order to detect the RSD and canny edge detector for processing of RSDF images. Finally, it is tested using ten different image sizes and the results show its better performance in terms of detection of RSD affected regions of fish and execution time.
Street-level collaboration: perception, power, and politics on the frontlines of collaboration
Authors: Jagannath Harish P. 
Published: April 2020

PurposeTo examine the implementation processes and outcomes of collaborative governance initiatives through the lens of bureaucratic politics.Design/methodology/approachAn in-depth single case study research design with 28 embedded cases to study the implementation of a collaborative governance initiative. This paper uses the analytical technique of process tracing to explicate necessary and sufficient conditions to uncover causal mechanisms and confirm descriptive and causal inferences.FindingsThis study finds that when street-level bureaucrats perceived the collaborative initiative as a health intervention (and not as a collaborative initiative), it resulted in low levels of stakeholder participation and made the collaborative initiative unsuccessful. This paper finds that bureaucratic politics is the causal mechanism that further legitimized this perception resulting in each stakeholder group avoiding participation and sticking to their departmental siloes.Research limitations/implicationsThis is a single case study about a revelatory case of collaborative governance implementation in India, and findings are analytically generalizable to similar administrative contexts. Further research is needed through a multiple case study design in a comparative context to examine bureaucratic politics in implementing collaborative initiatives.Practical implicationsPolicymakers and managers need to carefully consider the implications of engaging organizations with competing institutional histories when formulating and implementing collaborative governance initiatives.Originality/valueThis study's uniqueness is that it examines implementation of collaborative governance through a bureaucratic politics lens. Specifically, the study applies Western-centric scholarship on collaborative governance and street-level bureaucracy to a non-Western developing country context to push the theoretical and empirical boundaries of key concepts in public administration.

Published: April 2020

PurposeThis study aims to identify the impact of corporate governance on performance of sugar mills. In order to study this relation, a model is constructed in which ownership structure and independent directors are taken as independent variables. Whereas firm performance is analyzed by using proxy variables such as return on asset (ROA), return on equity (ROE) and sales growth. Moreover, size of board, working capital management (WCM) and philanthropy are taken as mediating variables between governance variables and firm performance.Design/methodology/approachThe data of 32 sugar mills listed at Pakistan Stock Exchange for the period of four years (i.e. 2014–2017) is used for this research. Moreover, to investigate the model, generalized least squares statistical method is used to measure the relationship between variables.FindingsThe results revealed that there is significant but positive relationship between independent directors and ROA while ownership structure and ROE have significant but negative relationship. Thus, the board of directors should make it sure that all stakeholders and organizations should increase the nonfamily ownership in firms for better corporate performance. Moreover, philanthropy and WCM mediate the relationship between corporate governance and firms' performance.Practical/implicationsThis research work will be helpful in the corporate governance, and further researchers can conduct their study by considering executive/nonexecutive director and institutional owners as governance variables.Originality/valueThis paper fulfills an identified need to study how Corporate Governance effect the performance of firm.
Art to enhance consumer engagement in the luxury fashion domain
Authors: Grassi Alessia 
Published: April 2020

PurposeThis paper explores an opportunity for luxury fashion brands to strengthen their engagement with consumers through the arts and without undermining the exclusivity of the luxury product.Design/methodology/approachThis paper is based on an interpretive qualitative approach aiming to specifically investigate Fondazione Prada – a contemporary art gallery owned and managed by the fashion brand Prada. Data were collected through semi-structured interviews and a focus group implemented with the “mystery shopper” technique. Template analysis was used to analyse the data.FindingsFondazione Prada has the potential for a deep engagement, but specific lack of dialogue and interaction needs to be addressed. Learning from and sharing values with the public through a two-way peer conversation elicited by contemporary art will benefit both the foundation and the fashion brand, in generating value as the result of a spillover effect. Thus, a significant competitive advantage might be gained.Originality/valueThis paper extends work on consumer brand engagement in physical and non-commercial “brand's places”, by evaluating the engagement provided by contemporary art foundations owned by luxury fashion brands. By leveraging the engaging nature of contemporary art, luxury fashion brands could provide an inclusive and engaging experience without undermining the characteristic of exclusivity of the luxury product and hence, gain a significant competitive advantage for the brand.

Published: April 2020

PurposeIn recent years, halal food industries are facing a high level of competition. The growing demand for halal food means firms are working hard to improve quality and reduce halal food defects. The purpose of this study is to propose a halal-based six sigma (SS) framework that could be used to reduce halal food defects and improve compliance.Design/methodology/approachThe proposed halal six sigma (HSS) framework has five phases based on the define-measure-analyse-improve-control (DMAIC) approach. The proposed framework also integrates halal assurance system requirements into HSS to ensure compliance. Tools used in the proposed model include SIPOC tools, Pareto diagram, root cause analysis and the improvement process flows. A case study in a chicken meat company is used to test and validate the proposed framework. In case of study research, brainstorming was used to review an initial proposed framework and focus group discussions were used to determine feasible improvement actions.FindingsThe results showed that the proposed HSS framework could be effective to detect and reduce the halal defects and lower the halal defect costs. By adopting the framework, the case firm was able to lower halal defect costs significantly and increase the SS level.Practical implicationsSS approach can be designed and adapted to specific food industry. HSS framework could provide a systematic approach to reduce halal food defects and sustain the improvement efforts. The proposed HSS framework is also easy to use to understand halal critical points and improve halal compliance.Originality/valueThis study proposed a HSS framework that can be adopted to reduce halal food defects and costs. This proposed framework will benefit the halal food industry intending to realize zero halal food defects and lower production costs. The limited number of publications in the research theme of halal food defects show that there is a significant gap in the existing body of knowledge.
Legitimizing black businesses: three examples from the Civil War to civil rights
Authors: Hollingsworth Keith 
Published: April 2020

Purpose
In “Reinventing Entrepreneurial History,” Wadhwani and Lubinski (2017) encourage the study of legitimacy, the sense that a new organization or venture “belongs” to, or fits within, the social construct of its time.

Design/methodology/approach
To this end, this query will consider methods used in the period between the Civil War and the Civil Rights Movement to show legitimacy in black economic endeavors. Three Atlanta entrepreneurs’ efforts will be used as demonstrative examples.

Findings
The overarching aim of this investigation of economic legitimization is to give practical examples of three distinct strategies in play: endorsement, authorization and storytelling. In addition, a fourth external actor, social organizations, that exists outside of the realms of media, government and law as noted by Bitektine and Haack (2015) is illustrated to grant validity within the black community. Also, the storytelling strategy is used to illustrate promoters, actors pushing legitimacy to benefit the community at large.

Originality/value
Arguably the search for economic and collective legitimacy within black businesses is not confined to the past. Stated in another way, black businesses still fight for legitimacy, and future research should be undertaken to show the similarities and differences in the two aforementioned periods.
An artificial-intelligence-based method for assessing service quality: insights from the prosthodontics sector
Authors: Martins Sara M. , Ferreira Fernando A.F. , Ferreira João J. M. , Marques Carla S.E. 
Published: April 2020

PurposeThe prosthodontics sector is facing major challenges because of scientific and technological advances that imply a clearer definition of lines of action and decision making processes. Measuring quality of service in this sector is a complex decision problem since the perceptions of three main players need to be considered: patients, dentists and dental technicians. This study sought to develop an artificial-intelligence-based (AI-based) method for assessing service quality in the dental prosthesis sector.Design/methodology/approachUsing strategic options development and analysis (SODA), which is grounded on cognitive mapping, and the measuring attractiveness by a categorical based evaluation technique (MACBETH), a constructivist decision support system was designed to facilitate the assessment of service quality in the dental prosthesis sector. The system was tested, and the results were validated both by the members of an expert panel and by the vice-president of the Portuguese association of dental prosthesis technicians.FindingsThe methodological process developed in this study is extremely versatile and its practical application facilitated the development of an empirically robust evaluation model in this study context. Specifically, the profile analyses carried out in actual clinics allowed the cases in which improvements are needed to be identified.Originality/valueAlthough already applied in the fields of AI and decision making, no prior work reporting the use of SODA and MACBETH for assessing service quality in the prosthodontics sector has been found.
Brand hate: a multidimensional construct
Authors: Zhang Chun , Laroche Michel 
Published: April 2020

Purpose
This study aims to examine the emotional components of brand hate and the variation of emotions across different levels of brand hate.

Design/methodology/approach
Study 1 uses in-depth interviews and data triangulation. Studies 2-5 make use of quantitative methods to test and validate the multidimensional structure of brand hate and the variation of its composing emotions.

Findings
Study 1 suggests that brand hate is a multidimensional construct comprised of anger-, sadness- and fear-related emotions; possible antecedents and consequences are discussed. The quantitative results from Studies 2-5 confirm the findings in Study 1. A three-factor scale consisting of nine items is developed. The proposed model is tested among different samples and is compared with the currently available brand hate models. In addition, the findings show that emotions weigh differently for different brand hate levels.

Research limitations/implications
This study contributes to the brand hate literature and provides a structure to understand brand hate more thoroughly.

Practical implications
Companies can benefit from the research through a better knowledge of brand hate. Managers can use the multidimensional measurement to detect brand hate and better cope with it.

Originality/value
This study is among the first few attempts to examine the multidimensionality of brand hate and to investigate the variation of emotions in different brand hate levels. This study contributes to a more precise description of the brand hate construct and improves understanding of consumer-brand relationships.
Evaluation of a participatory approach to improve healthy eating and physical activity in a secure mental health setting
Authors: Mateo-Urdiales Alberto , Michael Margaret , Simpson Charlotte , Beenstock Jane 
Published: April 2020

Purpose
The prevalence of obesity in secure mental health units is higher than in the general population, having a negative impact on the physical health and mental well-being of people with severe mental health illness (SMI). The purpose of this study was to describe the feasibility of a programme aimed to help people with SMI to eat healthily and be physically active.

Design/methodology/approach
A mixed-methods approach was used. A questionnaire administered to patients in both wards measured acceptability, demand, implementation and practicality of the project. Individual semi-structured interviews and focus groups were used to explore staff and patients’ perceptions of the project; as well as the barriers and enablers towards an effective implementation and participation in the project’s activities.

Findings
Patients were, overall, satisfied with the activities implemented. Successful activities were easy to implement, had staff actively engaged and did not require logistic or administrative planning beforehand. Barriers included unawareness around funding mechanisms of activities, staff capacity issues or lack of patients’ permission to leave the ward.

Originality/value
Few studies have assessed the feasibility of real-life interventions aimed to improve healthy eating and physical activity in secure mental health units. The results of this study can inform commissioners and providers of mental health services to design and implement new interventions and programmes.
A critical analysis of service ecosystems research: rethinking its premises to move forward
Authors: Mustak Mekhail , Plé Loic 
Published: April 2020

Purpose
This study aims to examine the development of service ecosystems literature and its four premises as follows: the characterization of service ecosystems as loosely coupled systems, the existence of shared institutional arrangements among actors, the occurrence of resource-integrating interactions among actors and value co-creation as the stated purpose of service ecosystems.

Design/methodology/approach
With a systematic literature review, the paper identifies and analyzes 98 articles on service ecosystems. An examination and a cross-check of the central elements of the articles reveal gaps and limitations in the analysis of service ecosystems. These results lead to the formulation of four propositions and suggestions for further research.

Findings
The four premises of service ecosystems are constrained by overly optimistic perceptions that prevent theoretical advancements. These premises overlook possible tight coupling; power asymmetries; divergent interpretations of institutions and institutional arrangements; divergent interpretations of actors’ resource-integrating actions, intentions and abilities; and the co-destruction of value. Four propositions are formulated to address these challenges.

Research limitations/implications
The shortcomings reflect the systematic literature review, which only covers a specific area of the extant knowledge base, namely, English-language articles published in peer-reviewed international journals.

Originality/value
This study extensively and critically investigates the premises of service ecosystems for the first time, proposing a more holistic, dynamic and realistic understanding of them. In so doing, it paves the way for renewed conceptualizations of service ecosystems.
Consistency at different levels
Authors: Su Tao Scofield , Chen Chunhua , Cui Xiaoyu , Yang Chunsheng , Ma Weimo 
Published: April 2020

PurposeThis paper aims to answer following three important but not well-answered or unanswered questions in the extant trust literatures: What is the true magnitude that trust impacts on performance? Is there any consistency among the effects of trust on performance at different levels? How does vertical distance affect the trust-performance relationship?Design/methodology/approachIt captures the law between trust and performance at different levels by conducting a meta-analytic examination consisting of 238 independent empirical studies, 586 effect sizes and 110,576 independent samples.FindingsIt makes a periodic conclusion that trust significantly promotes performance. Specifically, trust not only has stronger positive correlation with team performance than individual and organizational performance inside organization, but also strongly facilitates organizational performance between organizations. Moreover, consistency exits in the effects of trust on performance at different levels. On one hand, trust has stronger positive correlation with performance of contextual type than performance of innovative type than performance of task type at different levels. On the other hand, promotion effect of trust on performance strengthens when the vertical distance between trustors and trustees diminishes. Additionally, three potential moderators including publication status, measurement tool and common method variance moderate the focused relation, but moderating effect is not thorough for regional culture. Moderating directions of the above four potential moderators are highly consistent.Originality/valueThis paper answers the three important but not well-answered or unanswered questions.
