Abstract
Purpose
This paper aims to evaluate the effect of consumption of a high-fat diet (HFD) rich with total saturated fats on adiposity and serum levels of vascular cell adhesion molecule (sVCAM-1), a biomarker of endothelial inflammation/dysfunction. Another aim is to evaluate whether supplementation of a phytosomal formulation of curcumin would reduce adiposity measures and sVCAM-1 levels in HFD rats.
Design/methodology/approach
The study was conducted on 17 male rats which were allocated to one of three feeding regimen groups: normal diet (ND); HFD, or HFD with dietary phytosomal curcumin (HFD-C). Anthropometric measures were recorded weekly up to 20 weeks of feeding intervention, at the end of which, sVCAM-1 levels were also compared with one-way ANOVA and Tukey post-hoc analysis.
Findings
The HFD group had the greatest values for raw anthropometric data, and there was a group difference in anthropometric measures, however there was no significant difference between HFD and HFD-C for any measure. The gain at 20 weeks from initial values did reveal significant differences in weight and abdominal circumference between HFD and HFD-C groups. There were significant group differences in sVCAM-1 levels, with only HFD-C displaying significant lower levels than HFD group.
Originality/value
This is the first study that shows the capacity of a phytosomal formulation of curcumin in reducing adiposity and sVCAM-1 levels during daily intake of saturated fats above the recommended level. The results are promising in that this formulation can protect against endothelial inflammation/dysfunction, and can be used as complimentary therapy to suppress dyslipidemia/obesity-related cardiovascular complications.

Abstract
Purpose
This study aims to investigate how sustainability and ethics are being addressed both by the literature and companies. Furthermore, it seeks to identify the specific strategies that these companies use to foster ethical behaviour and promote sustainability in their business operations.
Design/methodology/approach
The study entails a bibliometric analysis and a set of case studies from a sample of companies working in different industry sectors. Based on these tools, it analyses whether – and how – enterprises are placing an emphasis on sustainability and ethics as part of their businesses. In addition, the selected companies' unethical practices or socially irresponsible corporate activities were investigated and presented.
Findings
The findings suggest that using an ethics perspective can be a valuable tool in improving the accuracy and correctness of business decision-making. In addition, the paper has identified the fact that sustainability standards can be used to improve customer satisfaction as many important issues are addressed. Finally, the paper highlights the importance of ethical considerations when designing and implementing sustainability standards at enterprises and the need for regulatory guidance in this regard.
Originality/value
The paper addresses the need for studies on how sustainability and ethics are being discussed by both the literature and companies. The paper presents some elements that can be used as possible corporate indicators for a wider implementation of sustainability and ethics objectives in enterprises.

Abstract
Purpose
The present study aims to investigate an unsuccessful implementation of an active learning methodology. Active learning methods have emerged in order to improve learning processes and increase students' roles in the classroom. Most studies on the subject focus on developing learning strategies based on successful implementations of such methods. Nevertheless, critical reflections on unsuccessful cases might also provide material for developing further contributions to this literature.
Design/methodology/approach
The authors conducted an intrinsic case study of an unsuccessful application of the flipped classroom method to an undergraduate basic statistics course at a Brazilian business school. The data collected comprised the course's syllabus, evaluation forms and two rounds of interviews with students and the professor.
Findings
The findings indicate that, apart from that which had been mapped by past literature, three additional aspects may limit the chances of successfully implementing a flipped classroom methodology: students' educational backgrounds, the course's structural issues and methodological and relational issues.
Originality/value
The present study contributes to the literature on active learning methodologies mainly by mapping additional aspects that should be considered in the implementation of the flipped classroom methodology. Additionally, the authors investigate an unsuccessful case of such an implementation, an investigation that is still scant within this literature.

Abstract
Purpose
This paper explores Lean Six Sigma principles and the DMAIC (define, measure, analyze, improve, control) methodology to propose a new Lean Six Sigma 4.0 (LSS 4.0) framework for employee occupational exams and address the real-world issue of high-variability exams that may arise.
Design/methodology/approach
This study uses mixed methods, combining qualitative and quantitative data collection. A detailed case study assesses the impact of LSS interventions on the exam management process and tests the applicability of the proposed LSS 4.0 framework for employee occupational exams.
Findings
The results reveal that changing the health service supplier in the explored organization caused a substantial raise in occupational exams, leading to increased costs. By using syntactic interoperability, lean, six sigma and DMAIC approaches, improvements were identified, addressing process deviations and information requirements. Implementing corrective actions improved the exam process, reducing the number of exams and associated expenses.
Research limitations/implications
It is important to acknowledge certain limitations, such as the specific context of the case study and the exclusion of certain exam categories.
Practical implications
The practical implications of this research are substantial, providing organizations with valuable managerial insights into improving efficiency, reducing costs and ensuring regulatory compliance while managing occupational exams.
Originality/value
This study fills a research gap by applying LSS 4.0 to occupational exam management, offering a practical framework for organizations. It contributes to the existing knowledge base by addressing a relatively novel context and providing a detailed roadmap for process optimization.

Abstract
Purpose
This study aims to explore the alignment between strategic plans of the Portuguese public higher education institutions (HEIs) and their perception of the integration of sustainability in education and curricula.
Design/methodology/approach
The strategic plans from 15 institutions were selected for content analysis; data about the integration of sustainability in education and curricula, from these HEI, were collected with an online questionnaire (self-report survey). Qualitative and quantitative analyses were performed.
Findings
Strategic plans of the Portuguese public HEIs seem to not be sufficiently aligned with self-assessment integration of sustainability in education and curricula.
Research limitations/implications
The classifications used in the content analysis were constructed and revised by the authors to reduce coder interpretation issues and subsequent bias in the results. However, some subjectivity could remain. The analysis of strategic plans and self-report surveys answered by top management, or a technician, does not assess the practices and sustainability implementation in education and curricula.
Practical implications
This study allows the self-report of already-implemented practices to be compared to the planned strategy of HEI governance in Portugal as stated in their strategic plans.
Originality/value
An analysis and respective insights on the lack of connection between strategic planning and self-report practices about sustainability implementation, using Portugal as a case study.

Abstract
Purpose
After deciding to become agile, many information technology (IT) units struggle; they underestimate the needed managerial expertise to alter their current culture toward an agile one, particularly when cross-cultural (f)actors are involved. Given that work values are the key to an organizational culture, the study derived a set of agile work values of culturally diverse IT professionals together with a set of well-known generic work values. Consequently, the authors illustrate that managers in charge of the transition to an effective agile culture must pay serious attention to the specific value constellations of its often highly diverse workforce.
Design/methodology/approach
A literature review resulted in an initial list of agile work values. Then, mainly through a Delphi round, 12 agile-specific work values were established. These were survey rated, along with the validated set of 18 generic work values, by 102 British and Indian IT professionals in a digital service and consulting firm that was requested by its client to become agile. The observations made in 14 feedback group-interview-type dialogs enriched the surveyed data further.
Findings
In the current exploratory study, four generic value dimensions were complemented by two agile-specific ones: team communication and shared responsibility. Among the British and Indian (on-site and offshore) workers, only 2 of the 30 current work values were shared while 7 significant value differences were found, explaining the noted employee bitterness, productivity losses and client disengagement. This situation was reflected in the many discrepancies between the professionals' ideal agile way of working and how their unit was currently functioning.
Originality/value
The multi-method study shows an over-optimistic approach to becoming agile in a common cross-cultural context; insights are gained on how to optimize agile ways of organizing IT work when British IT workers collaborate with Indian IT workers. It may benefit many agile practitioners and managers working with(in) cross-culturally mixed and partly remote teams.

Abstract
Purpose
The purpose of this paper is to analyze international orange trade as different types of orange juice seem to obtain the favor of newer food consumption patterns as opposed to fresh oranges. In addition, the authors will outline market tendencies that could be useful to stakeholders interested in any way in the sector.
Design/methodology/approach
This document uses the Lafay index (LFI) in order to evaluate the intra-sectoral trade specialization; however, the social network analysis (SNA) approach is used to connect the international trade relations and to refine, classify and prioritize the countries having a central role in the orange juice world trade network. For both indexes, UNCOMTRADE has been used.
Findings
The findings show that the growing orange juice trade is the leading global growth factor as opposed to the sale of fresh oranges. It appears that major trade revenues come from orange juice concentrate (Frozen Concentrated Orange Juice (FCOJ)). Business takes place mostly in Europe.
Originality/value
This study shows for the first time that the current orange juice export competitiveness is crucial to the long-term survival of the orange sector. This study valuably contributes to the less known literature regarding FCOJ and Not From Concentrate orange juice trade relevance.

With the aid of naturalistic simulations, this paper aims to investigate human behavior during manual and autonomous driving modes in complex scenarios.
Abstract
Purpose
With the aid of naturalistic simulations, this paper aims to investigate human behavior during manual and autonomous driving modes in complex scenarios.
Design/methodology/approach
The simulation environment is established by integrating virtual reality interface with a micro-simulation model. In the simulation, the vehicle autonomy is developed by a framework that integrates artificial neural networks and genetic algorithms. Human-subject experiments are carried, and participants are asked to virtually sit in the developed autonomous vehicle (AV) that allows for both human driving and autopilot functions within a mixed traffic environment.
Findings
Not surprisingly, the inconsistency is identified between two driving modes, in which the AV’s driving maneuver causes the cognitive bias and makes participants feel unsafe. Even though only a shallow portion of the cases that the AV ended up with an accident during the testing stage, participants still frequently intervened during the AV operation. On a similar note, even though the statistical results reflect that the AV drives under perceived high-risk conditions, rarely an actual crash can happen. This suggests that the classic safety surrogate measurement, e.g. time-to-collision, may require adjustment for the mixed traffic flow.
Research limitations/implications
Understanding the behavior of AVs and the behavioral difference between AVs and human drivers are important, where the developed platform is only the first effort to identify the critical scenarios where the AVs might fail to react.
Practical implications
This paper attempts to fill the existing research gap in preparing close-to-reality tools for AV experience and further understanding human behavior during high-level autonomous driving.
Social implications
This work aims to systematically analyze the inconsistency in driving patterns between manual and autopilot modes in various driving scenarios (i.e. multiple scenes and various traffic conditions) to facilitate user acceptance of AV technology.
Originality/value
A close-to-reality tool for AV experience and AV-related behavioral study. A systematic analysis in relation to the inconsistency in driving patterns between manual and autonomous driving. A foundation for identifying the critical scenarios where the AVs might fail to react.

Abstract
Purpose
The study aims to map the links between Industry 4.0 (I-4.0) technologies and circular economy (CE) for sustainable operations and their role to achieving the selected number of sustainable development goals (SDGs).
Design/methodology/approach
The study adopts a systematic literature review method to identify 76 primary studies that were published between January 2010 and December 2020. The authors synthesized the existing literature using Scopus database to investigate I-4.0 technologies and CE to select SDGs.
Findings
The findings of the study bridge the gap in the literature at the intersection between I-4.0 and sustainable operations in line with the regenerate, share, optimize, loop, virtualize and exchange (ReSOLVE) framework leading to CE practices. Further, the study also depicts the CE practices leading to the select SDGs (“SDG 6: Clean Water and Sanitation,” “SDG 7: Affordable and Clean Energy,” “SDG 9: Industry, Innovation and Infrastructure,” “SDG 12: Responsible Consumption and Production” and “SDG 13: Climate Action”). The study proposes a conceptual framework based on the linkages above, which can help organizations to realign their management practices, thereby achieving specific SDGs.
Originality/value
The originality of the study is substantiated by a unique I-4.0-sustainable operations-CE-SDGs (ISOCES) framework that integrates I-4.0 and CE for sustainable development. The framework is unique, as it is based on an in-depth and systematic review of the literature that maps the links between I-4.0, CE and sustainability.
