Abstract
Purpose
This paper aims to investigate the forces that influence the shifting of professional boundaries on the entry of a new medical occupation in Dutch hospitals – non‐specialist emergency physicians.
Design/methodology/approach
Five case studies of Dutch hospitals were conducted and the emergency physicians' implementation process was analyzed by means of force field analysis.
Findings
Emergency physicians were conceptualized as being the answer to unequivocal contextual changes. However, their contribution to better performance varies due to problems in the implementation process. Strong socio‐political forces between traditional specialties and these new doctors mediate the intended improvement. The emergency physicians aim to establish their own organizational‐, patient‐ and knowledge‐domain by redrawing professional boundaries but they are not on a par with the specialists who set these boundaries. Consequently, emergency physicians only gradually redraw the existing boundaries, resulting in limited added value. Their reaction is to obtain power by striving to develop into a recognized specialty; ironically, by becoming an additional layer in the traditional medical hierarchy they might lose their envisaged added value.
Research limitations/implications
This paper is based on the first Dutch hospitals that implemented emergency physicians. The number of cases is therefore limited. Moreover, the study took place at an early stage of emergency physician implementation.
Practical implications
The extent of successful redrawing depends on the implementation's transition logic, the existing degree of differentiation and boundary permeability and on the ideological power developed by the leaders.
Originality/value
The introduction of emergency physicians is currently being discussed in many countries worldwide, and some countries consider following the Dutch example of non‐specialist doctors. This paper supports health professionals and hospital managers in not falling prey to the same pitfalls as some Dutch hospitals.

Abstract
Purpose
The purpose of this paper is to identify the critical success factors (CSFs) of integrated quality environmental management (IQEM) and analyze their impact on operational performance (OP) and environmental performance (EP) in food processing Small and medium-sized enterprises (SMEs) in Pakistan.
Design/methodology/approach
The study is based on collecting data using a survey questionnaire through snowball sampling technique. A total of 302 food processing SMEs operating in Punjab, Pakistan, responded to the survey. SPSS version-23 and SmartPLS-3 were used for data analysis.
Findings
The literature review identified leadership (LS), employee management (EM), strategic planning (SP), information management (IM), process management (PM), supplier management (SM) and customer focus (CF) as CSFs of IQEM. The results of this study found a significant relationship of all identified CSFs with operational performance in food processing SMEs whereas EM, IM, PM and SM were insignificant with the EP in the food processing SMEs.
Research limitations/implications
Although this study has collected data from one province, the Punjab province, it still relevant in identifying the CSFs for IQEM implementation within food processing SMEs to improve performance.
Originality/value
Despite the wide spread of integrated systems practices in the developed countries, little attention has been placed to implement and assess the IQEM initiatives by organizations in the developing countries. Thus, this study identified CSFs of IQEM based on empirical studies and analyzed their impact on OP and EP of food processing SMEs.

Abstract
Purpose
The purpose of this paper is to propose a novel algorithm which hybridizes the best features of three basic algorithms, i.e. genetic algorithm, bacterial foraging, and particle swarm optimization (PSO) as genetically bacterial swarm optimization (GBSO). The implementation of GBSO is illustrated by designing the fuzzy pre‐compensated PD (FPPD) control for two‐link rigid‐flexible manipulator.
Design/methodology/approach
The hybridization is carried out in two phases; first, the diversity in searching the optimal solution is increased using selection, crossover, and mutation operators. Second, the search direction vector is optimized using PSO to enhance the convergence rate of the fitness function in achieving the optimality. The FPPD controller design objective was to tune the PD controller constants, normalization, and denormalization factors for both the joints so that integral square error, overshoots, and undershoots are minimized.
Findings
The proposed algorithm is tested on a set of mathematical functions which are then compared with the basic algorithms. The results showed that the GBSO had a convergence rate better than the other algorithms, reaching to the optimal solution. Also, an approach of using fuzzy pre‐compensator in reducing the overshoots and undershoots for loading‐unloading and circular trajectories had been successfully achieved over simple PD controller. The results presented emphasize that a satisfactory tracking precision could be achieved using hybrid FPPD controller with GBSO.
Originality/value
Simulation results were reported and the proposed algorithm indeed has established superiority over the basic algorithms with respect to set of functions considered and it can easily be extended for other global optimization problems. The proposed FPPD controller tuning approach is interesting for the design of controllers for inherently unstable high‐order systems.

Abstract
Purpose
This paper aims to automatically generate load shedding sequences due to insufficient power supply, to ensure flight safety and complete flight task.
Design/methodology/approach
In this paper, a power allocation and load management model, including logical and physical submodels of the distribution system, is first established according to different requirements of the loads in different flight phase and the current total power supply. Then, an optimal load management scheme based on an improved ant colony algorithm is proposed to automatically generate load shedding sequences for both safety-critical and nonsafety critical loads, to achieve a reliable and safe power supply.
Findings
To verify the efficiency and feasibility of the algorithm, the proposed method is verified in a virtual simulation platform. Simulation result illustrates that the proposed algorithm is efficient and feasible.
Practical implications
The proposed method can provide guidance on load power supply when the civil aircraft is under abnormal power supply situation.
Originality/value
An optimal load management scheme is proposed by considering different requirements of the loads in different flight phase and the current total power supply.

Abstract
Purpose
The purpose of this paper is to suggest a practical means of incorporating ecological capital into the framework of business entities. Investors and shareholders need to be informed of the viability and sustainability of their investments. Ecological (natural) capital risks are becoming more significant. Exposure to material risk from primary industry is a significant factor for primary processing, pharmaceutical, textile and the financial industry. A means of assessing the changes to ecological capital assets and their effect on inflows and outflows of economic benefit is important information for stakeholder communication.
Design/methodology/approach
This paper synthesises a body of literature from accounting, ecological economics, ecosystem services, modelling, agriculture and ecology to propose a way to fill current gaps in the capability to account for ecological capital. It develops the idea of the ecological balance sheet (EBS) to enable application of familiar methods of managing built and financial capital to management of ecological assets (ecosystems that provide goods and services).
Findings
The EBS is possible, practical and useful. A form of double-entry bookkeeping can be developed to allow accrual accounting principles to be applied to these assets. By using an EBS, an entity can improve its capability to increase inflows and avoid future outflows of economic benefit.
Social implications
Although major efforts are under-way around the world to improve business impact on natural resources, these efforts have been unable to satisfactorily help individual businesses elucidate the practical economic and competitive advantages conferred by investment in ecological capital. This work provides a way for businesses to learn about what the impact of changes to ecological assets has on inflows and outflows of economic benefit to their enterprise and how to invest in ecological capital to reduce their enterprise’s material risk and create competitive advantage.
Originality/value
No one has synthesised knowledge and practice across these disciplines into a practical approach. This approach is the first demonstration of how ecological assets can be managed in the same way as built capital by using proven practices of accounting.

Abstract
Purpose
This study aims to investigate the link between carbon emissions and market value for nonfinancial companies in the STOXX Europe 600 index, with a specific focus on the moderating effect of executive compensation.
Design/methodology/approach
To achieve the study’s purpose, this study uses data from the STOXX Europe 600 index between 2010 and 2021. The researchers use ordinary least squares regression analysis to examine the relationship between carbon emissions and market value while taking into account the moderating effect of executive compensation. The study also uses additional tests, such as the dynamic two-step system generalized method of moments regression and the difference in differences method.
Findings
The study reveals four key findings. First, there is a statistically significant negative relationship between carbon emissions and market value. Second, executive compensation has a negative moderating effect on the association between carbon emissions and market value. Third, Say-on-Pay regulations can encourage companies to adopt environmentally responsible practices, which can positively impact their market value. Finally, the study shows that the Paris Agreement motivates companies to prioritize sustainability, leading to potentially higher market values for those that are more environmentally responsible.
Practical implications
This study highlights the importance of considering environmental sustainability in corporate decision-making. It suggests that prioritizing sustainability can lead to financial benefits, as companies with lower carbon emissions tend to have higher market values. The findings also have important implications for regulators and investors.
Originality/value
This study provides novel insights into the link between carbon emissions and market value and the moderating effect of executive compensation. It also sheds light on the potential impact of Say-on-Pay regulations and the Paris Agreement on corporate sustainability practices and market values.

Abstract
Purpose
The purpose of this paper is to examine the influence of anticipated emotions (AE) on behavioural intention and behaviour to consume filled chocolates and to give an indication on the possible differences in consumer behaviour between two countries.
Design/methodology/approach
The theory of planned behaviour (TPB) was used to explain the consumption of chocolate. In this study, TPB is extended with a construct for AE.
Findings
A total of 859 consumers in Belgium and Hungary participated in the study and results showed that including AE increases the predicted variance of the TPB. Moreover, AE have a positive effect on the intention and the actual behaviour of consumers. Next, the study suggests that Belgian consumers are more influenced by their emotional and control beliefs and that Hungarian consumers are also driven by opinion of family and friends and some behavioural beliefs.
Practical implications
Overall, TPB can contribute to the understanding of behavioural intention and behaviour towards eating filled chocolate. Moreover, it can help to develop a marketing plan for specific consumer segments as it can identify influencing factors and consumer beliefs towards a product.
Originality/value
This is the first study that compares the fit of the TPB model with and without the construct of AE. The work contributes to the growing literature on emotions as it does not focus on emotions elicited during or after consumption, but explores if the AE also play a significant role in behaviour.

The purpose of this paper is to investigate the efficacy of bacterial exopolysaccharides (Eps) in reactive black 5 (RB5) textile dye wastewater bioremediation.
Abstract
Purpose
The purpose of this paper is to investigate the efficacy of bacterial exopolysaccharides (Eps) in reactive black 5 (RB5) textile dye wastewater bioremediation.
Design/methodology/approach
The Eps were produced by bacteria isolated from cotton gin trash soils collected from different cotton-growing regions in Kenya for comparison purposes. A broth medium reconstituted using molasses was assessed for its capacity to produce the Eps. RB5 textile dye wastewater was optimized for dye removal under different temperatures, times and molasses concentrations. Dye removal was studied by Lovibond-Day Light Comparator, UV–Vis spectrophotometer and FTIR.
Findings
It was found that cotton gin trash soils contained Eps-producing bacteria. Three of the Eps studied were found to have the capacity to remove at least 80% of the dye from the wastewater.
Research limitations/implications
This research did not assess the efficacy of the RB5 dye removal from the wastewater by mixtures of the Eps.
Practical implications
Bioremediation of textile dye wastewater with Eps produced by bacteria cultured from cotton gin trash soil is significant because it will offer an effective and cleaner alternative to the chemical coagulants.
Social implications
Alternative treatment of textile wastewater with the Eps would result in safer water being released into the water bodies as opposed to the chemically treated wastewater that contains remnant chemicals.
Originality/value
Research on the use of Eps produced by bacteria isolated from cotton gin trash soils for removal of RB5 dye from textile wastewater has not been done before.

Abstract
Purpose
Sustainability investors are in need of updated standards, indexes and in general better tools and instruments to facilitate company information on its impacts on people, planet and profit. Such instruments to reveal reliable, independent metrics and indicators to evaluate companies’ performances on sustainability exist, however, in research fields that previously have not been used extensively, for instance, life cycle assessments (LCAs). ISO 14001:2015 has implemented life cycle perspective, however, without being explicitly clear on which methodology is preferred. This paper aims to investigate LCA as to improve companies’ transparency towards sustainability investors through a literature review on sustainable investment evaluation.
Design/methodology/approach
The literature review is conducted through the search engine Google Scholar, which to date hosts the most comprehensive academic database across other databases such as Scopus, ISI Web of Knowledge, Science Direct, etc. Search words such as “Sustainable finance”, “Sustainable Investments”, “Performance metrics”, “Life cycle assessment”, “LCA”, “Environmental Management Systems”, “EMS” and “Environmental Profit and Loss Account” were used. Special journals that publish research on LCA such as International Journal of Life Cycle Assessment, Journal of Cleaner Production and Journal of Industrial Ecology were also investigated in-depth.
Findings
The combination of using LCA in, for instance, environmental profit and loss accounts studied in this paper shows a comprehensive and reliable tool for sustainability investors, as well as for social responsibility standards such as ISO 14001, ISO 26000, UN Global Compact, GIIN, IRIS and GRI to incorporate. With a LCA-based hybrid input-output account, both upstream and downstream’s impact on the environment and society can be assessed by companies to attract more funding from sustainability investors such as shareholders, governments and intergovernmental bodies.
Research limitations/implications
The literature review is based on publicly disclosed academic papers as well as five displayed company Environmental Profit and Loss accounts from the Kering Group, PUMA, Stella McCartney company, Novo Nordisk and Arla Group. Other company experiences with integration of LCA as a reporting tool have not been found, yet it is not to conclude that these five companies are the only ones to work extensively with LCA.
Practical implications
The paper may contribute to the clarification of LCA-thinking and perspective implementation in both ISO 14001 and ISO 26000, as well as in other social responsibility standards such as the UN Global Compact, the Global Impact Investing Networks, IRIS performance metrics, the Global Reporting Initiative and others.
Originality/value
The paper is one of the first that evaluates LCA and environmental profit and loss accounts for sustainability investors, as well as for consideration of implementation in social responsibility standards such as the ISO 14001 and ISO 26000, as well as in other social responsibility standards such as the UN Global Compact, the Global Impact Investing Networks, IRIS performance metrics and the Global Reporting Initiative.
