Abstract
Purpose
This study estimates the land footprint, nutrients and monetary value of persimmon loss in Brazil, and also consolidated the methodological approach for assessing resources related to food loss.
Design/methodology/approach
It uses data on the harvested area, production, production loss and production value of persimmon in Brazil from 2014 to 2019. The persimmon loss in Brazil was converted into macro- and micronutrients, land use and monetary value.
Findings
The average annual production loss, loss production value and land footprint of persimmon are 35,100 tons, US$12m and 1,673 hectares, respectively. Persimmon loss represents the average loss per year of 6.6bn grams of carbohydrates, 1.6bn grams of food fibers, 7.2bn milligrams of vitamin C, 41.8bn micrograms of vitamin A, 4.5bn milligrams of calcium and 54.8bn milligrams of potassium. These nutrients have the potential to meet the nutritional daily needs of approximately 135,000, 176,000 people, 270,000, 164,000, 12,000 and 32m, respectively.
Practical implications
Through (1) research and innovation; (2) infrastructure development; (3) training and education; (4) collaboration and networking; and (5) market diversification and value addition, people can increase persimmon shelf life, reduce postharvest losses and create a resilient environment for small persimmon farmers. This approach promotes sustainability in the agri-food system and empowers stakeholders.
Originality/value
This investigation helps to understand the value of food loss, considering the use of natural resources, as well as the loss of nutrients and monetary value.

Abstract
Purpose
This paper aims to focus on the finite element method in the frequency domain (FD-FEM) for the transient electric field in the non-sinusoidal steady state under the non-sinusoidal periodic voltage excitation.
Design/methodology/approach
Firstly, the boundary value problem of the transient electric field in the frequency domain is described, and the finite element equation of the FD-FEM is derived by Galerkin’s method. Secondly, the constrained electric field equation on the boundary in the frequency domain (FD-CEFEB) is also derived, which can solve the electric field intensity on the boundary and the dielectric interface with high accuracy. Thirdly, the calculation procedures of the FD-FEM with FD-CEFEB are introduced in detail. Finally, a numerical example of the press-packed insulated gate bipolar transistor under the working condition of the repetitive turn-on and turn-off is given.
Findings
The FD-CEFEB improves numerical accuracy of electric field intensity on the boundary and interfacial charge density, which can be achieved by modifying the existing FD-FEMs’ code in appropriate steps. Moreover, the proposed FD-FEM and the FD-CEFEB will only increase calculation costs by a little compared with the traditional FD-FEMs.
Originality/value
The FD-CEFEB can directly solve the electric field intensity on the boundary and the dielectric interface with high accuracy. This paper provides a new FD-FEM for the transient electric field in the non-sinusoidal steady state with high accuracy, which is suitable for combined insulation structure with a long time constant.

Abstract
Purpose
For many years, universities have been confronted with the rise of a managerial logic, in line with the new public management movement. They have been encouraged to implement new accounting tools such as cost calculations. Literature shows mixed results regarding the institutionalization of such tools, and the logic they try to support. In most studies, the agency of actors is examined to explain the institutionalization of accounting tools and only few studies consider the specific characteristics of these accounting tools to understand this process. To enrich the literature on institutionalization, this article examines how the affordances of costing tools affect the institutionalization of these tools and the institutionalization of new logics in pluralistic organizations such as universities.
Design/methodology/approach
The data were collected at a French university which is considered as an example of successful institutionalization of the tool and is cited as a model to follow. The data include a four-month participant observation and 18 interviews. Access to internal and external documents was also available. The analysis of the data is based on a framework proposed by Jarzabkowski and Kaplan (2015), which draws on the concept of affordance of tools, to investigate how the possibilities and constraints of costing tools shape the selection, application and outcomes of cost calculations.
Findings
The results show that the affordances of cost calculations facilitate the institutionalization of a new logic and its coexistence with previous logics. Technical affordances are mobilized by actors aiming to bring in a new logic without directly confronting the old ones. Role affordances also play a major role in the institutionalization by facilitating the adhesion of the actors through multiple applications of the tool. Finally, value-based affordances reinforce the institutionalization of a managerial logic by emphasizing the values shared with the other logics and thus facilitating the coexistence of the three logics at stake in the university.
Originality/value
This research provides three main contributions. First, it contributes to the literature on the institutionalization of accounting tools. It shows the relevance of the concept of affordance (Leonardi and Vaast, 2017) to unpack the characteristics of accounting tools (including the constraints and the possibilities they offer) and to achieve a better understanding of the institutionalization of accounting tools. Second, this paper contributes to the literature dealing with the role of accounting tools in the institutionalization of logics. The results suggest that the institutionalization of tools and the institutionalization of logics are two different phenomena that move at different speeds. However, these phenomena interact: the institutionalization of accounting tools can facilitate the coexistence of different logics in pluralistic organizations. Third, this paper contributes to the literature on affordances. The data reveal several types of affordances for accounting tools: technical affordances that refer to the technical possibilities to shape and tweak the tool; role affordances that refer to the various roles and purposes that the tool can fulfill and value-based affordances that refer to the plasticity of the values and beliefs that the tool can convey. The study shows that each type of affordance is prevalent at a different time of the process of institutionalization and that the combination of these affordances contributes to the institutionalization of the tool and of new logics.

Abstract
Purpose
In this context, this study aims to obtain information about the noise levels emitted to the environment by modeling the noise map of Dalaman Airport and correlating these noise values according to the Environmental Noise Directive (END) and World Health Organization (WHO) limits.
Design/methodology/approach
Dalaman Airport Aeronautical Information Publication and 2022 flight data from the airport were analyzed. The noise levels exposed to schools and health institutions were determined using the Cnossos–Eu calculation method.
Findings
Maximum noise levels were obtained as Lden 92.29 dB(A), Lday 85.24 dB(A), Levening 89.00 dB(A) and Lnight 85.23 dB(A) according to the noise indicators. Limit values recommended by the END and WHO according to noise indicator types and measurement results were correlated and evaluated.
Originality/value
In the noise modeling of Dalaman Airport, there has previously been no evaluation of the noise limits recommended according to END or WHO in the literature.

Abstract
Purpose
Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.
Design/methodology/approach
Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.
Findings
For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.
Originality/value
The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.

Abstract
Purpose
In developing countries, how risk management technologies influence management accounting and control (MAC) practices is under-researched. By drawing on insights from institutional studies, this study aims to examine the multiple institutional pressures surrounding an entity and influencing its risk-based management control (RBC) system – that is, how RBC appears in an emerging market attributed to institutional multiplicity.
Design/methodology/approach
The authors used qualitative case study research methods to collect empirical evidence from a privately owned Egyptian insurance company.
Findings
The authors observed that in the transformation to risk-based controls, especially in socio-political settings such as Egypt, changes in MAC systems were consistent with the shifts in the institutional context. Along with changes in the institutional environment, the case company sought to configure its MAC system to be more risk-based to achieve its strategic goals effectively and maintain its sustainability.
Originality/value
This research provides a fuller view of risk-based management controls based on the social, professional and political perspectives central to the examined institutional environment. Moreover, unlike early studies that reported resistance to RBC, this case reveals the institutional dynamics contributing to the successful implementation of RBC in an emerging market.

Abstract
Purpose
This paper introduces a novel quality measure, the percent-within-distribution, or PWD, for acceptance and payment in a quality control/quality assurance (QC/QA) performance specification (PS).
Design/methodology/approach
The new quality measure takes any sample size or distribution and uses a Bayesian updating process to re-estimate parameters of a design distribution as sample observations are fed through the algorithm. This methodology can be employed in a wide range of applications, but the authors demonstrate the use of the measure for a QC/QA PS with upper and lower bounds on 28-day compressive strength of in-place concrete for bridge decks.
Findings
The authors demonstrate the use of this new quality measure to illustrate how it addresses the shortcomings of the percent-within-limits (PWL), which is the current industry standard quality measure. The authors then use the PWD to develop initial pay factors through simulation regimes. The PWD is shown to function better than the PWL with realistic sample lots simulated to represent a variety of industry responses to a new QC/QA PS.
Originality/value
The analytical contribution of this work is the introduction of the new quality measure. However, the practical and managerial contributions of this work are of equal significance.

Abstract
This chapter aims to shed light on the hidden benefits and losses of US-China trade within the framework of unequal exchange theory. After presenting the evolutions of the trade balance between China and the United States, we propose two methods for measuring the unequal exchange between them: one considers the labor content directly incorporated into the exchange; the other focuses on the international values with input-output tables. This allows to present a synthesis of sectoral analyses. Our results show a significant unequal exchange in US-China trade over 1995–2014, the United States being actually the main beneficiary of this trade. Both methods exhibit the inequality in exchange tending to decrease over time; China's disadvantage has been gradually reducing from the 2000s. We finally suggest that the relative decline in the hegemonic status of the United States in this bilateral unequal relationship could help explain its decision to launch its trade war with China.

Abstract
Purpose
This study aims to explore how emerging SMEs respond to the multifaceted contents of CSR-related code of conduct (COC) from external stakeholders and the underlying constraining forces and mechanisms shaping such responses.
Design/methodology/approach
This study opted for a qualitative methodology using the content analysis, and the data were collected from the auditing reports on Chinese export-oriented SMEs carried out by a public and independent third-party agency.
Findings
The findings showed that SMEs from emerging markets present a short-termism orientation in the response to external CSR-related COC, and the study developed a threefold response typology implemented by SMEs, capturing economic interest and moral rightness as two dimensions shaping such responsive patterns. The study furthermore showed that whether SMEs' responses are more symbolic or substantive depends on managers' beliefs regarding the economic-moral conflict tension involved in the implementation of CSR-related COC.
Originality/value
This paper explores emerging SMEs' response strategy to CSR-related issues formulated by external stakeholders and clarifies the underlying decision-making road map to alleviate the tension involved in corporate social responsibility implementation.

This paper aims to study the impact of transient velocity changes on sealing performance during reciprocating sealing processes.
Abstract
Purpose
This paper aims to study the impact of transient velocity changes on sealing performance during reciprocating sealing processes.
Design/methodology/approach
Establish a model of transient mixed lubrication, solve the transient Reynolds equation, consider the effect of temperature rise at the seal interfaces, and determine the behavior of the seal interfaces, such as film thickness and fluid pressure. Evaluation with friction and leakage rate, calculate the variation of sealing performance with reciprocating velocity under different working conditions, and verify it through bench experiments.
Findings
Within a reciprocating stroke, the frictional force decreases with increasing velocity, and the frictional force of the outstroke is greater than that of the instroke; at the time of the stroke transition, the fluid pressure is smallest and the rough peak contact pressure is greatest. At present, the dynamic pressure effect of fluids is the largest, and the friction force also increases, which increases the risk of material wear and failure. Friction and leakage increase with increasing pressure and root mean square roughness. As temperature increases, friction increases and leakage decreases. In studying the performance variations of seal components through a reciprocating sealing experiment, it was found that the friction force decreases with increasing velocity, which is consistent with the calculated results and more similar to the calculated results considering the temperature rise.
Originality/value
This study provides a reference for the study of transient sealing performance.
