Abstract
Purpose
From the quantum game perspective, this paper aims to study a green product optimal pricing problem of the dual-channel supply chain under the cooperation of the retailer and manufacturer to reduce carbon emissions.
Design/methodology/approach
The decentralized and centralized decision-making optimal prices and profits are obtained by establishing the classical and quantum game models. Then the classical game and quantum game are compared.
Findings
When the quantum entanglement is greater than 0, the selling prices of the quantum model are higher than the classical model. Through theoretical research and numerical analysis results, centralized decision-making is more economical and efficient than decentralized decision-making. Publicity and education on carbon emission reduction for consumers will help consumers accept carbon emission reduction products with slightly higher prices. When the emission reduction increases too fast, the cost of emission reduction will form a significant burden and affect the profits of manufacturers and supply chain systems.
Originality/value
From the perspective of the quantum game, the author explores the optimal prices of green product and compares them with the classical game.

Abstract
Purpose
The current paper is a brief review of the emerging field of quantum-like modelling in game theory. This paper aims to explore several quantum games, which are superior compared to their classical counterparts, which means either they give rise to superior Nash equilibria or they make the game fairer. For example, quantum Prisoners Dilemma generates Pareto superior outcomes as compared to defection outcome in the famous classical case. Again, a quantum-like version of cards game can make the game fairer, increasing the chance of winning of players who are disadvantaged in the classical case. This paper explores all the virtues of simple quantum games, also highlighting some findings of the authors as regards Prisoners Dilemma game.
Design/methodology/approach
As this is a general review paper, the authors have not demonstrated any specific mathematical method, rather explored the well-known quantum probability framework, used for designing quantum games. They have a short appendix which explores basic structure of Hilbert space representation of human decision-making.
Findings
Along with the review of the extant literature, the authors have also highlighted some new findings for quantum Prisoners Dilemma game. Specifically, they have shown in the earlier studies (which are referred to here) that a pure quantum entanglement set up is not needed for designing better games, even a weaker condition, which is classical entanglement is sufficient for producing Pareto improved outcomes.
Research limitations/implications
Theoretical research, with findings and implications for future game designs, it has been argued that it is not always needed to have true quantum entanglement for superior Nash Equilibria.
Originality/value
The main purpose here is to raise awareness mainly in the social science community about the possible applications of quantum-like game theory paradigm. The findings related to Prisoners Dilemma game are, however, original.

Abstract
Purpose
This paper aims to demonstrate that fundamental aspects of quantum theory can be applied to work in information studies (IS).
Design/methodology/approach
The field of information studies is so broad and extensive that it requires similar breadth of epistemic and methodological features in order to fulfill its inherent promise as a human enterprise. Quantum theory holds promise as a way to shape questions and inquiry in information studies (IS).
Findings
The revolutionary elements of quantum theory, such as entanglement, nonlocality, etc. can be applied to information, especially language‐based communication.
Research limitations/implications
Perhaps most especially, the non‐ or extra‐mathematical components of quantum theory offer ontological and epistemic modes of thought which apply to information. Those modes of thought are ripe with conceptual promise for examination of, for example, information as objective entity and as complex material substance. This paper explores some of the potentially promising ways to explore information as a complex phenomenon.
Originality/value
While some work in IS has considered quantum phenomena, there has not been a thorough investigation of the theory's application to inquiry in IS.

Abstract
Purpose
The replenishment of construction materials heavily relies on the functioning of heavy machinery, which often leads to confusion and negotiations among construction work groups regarding the allocation rights of these materials. When multiple groups require the same construction materials, they often struggle to determine whether the delivered materials are intended for their own use or if they have encroached upon supplies designated for others. Such uncertainties and negotiations frequently result in delays in construction progress and have the potential to escalate into conflicts. To minimize misunderstandings among work groups and mitigate the risk of severe safety consequences, it is crucial to understand the decision-making processes involved in the interaction between work groups.
Design/methodology/approach
This paper adopts a game theory approach to examine the interactions among work groups from a safety perspective. Quantum response equilibrium (QRE), as a specialized form of game with incomplete information, is assumed to govern the behavior of work groups in this study. By conducting a questionnaire survey, interactive scenarios were simulated. A resource overlap scenario for high-altitude construction is established, with the key factors being the importance of construction materials, the time required to supplement materials, whether managers are present and the climate within the groups. The model parameters were estimated using the expectation–maximization algorithm. Additionally, individual traits and safety awareness are surveyed in the questionnaire, further explaining the results of the game.
Findings
The findings indicate that the likelihood of conflicts between work groups under resource overlap can be quantified. The radical behavior of construction work groups exhibits a positive correlation with the importance of construction materials and the time required for material replenishment. Furthermore, the presence of a safety climate and the oversight of management personnel play a significant role in maintaining the composure of construction work groups. The expanded results of the questionnaire demonstrate that there is considerable room for improvement in workers' safety awareness, and management approaches can be further enhanced to prevent unsafe behaviors from occurring.
Originality/value
A novel game theory model was developed to evaluate the behavior of construction groups in situations of resource overlap. This model offers practical suggestions to improve safety performance and efficiency in construction projects.

Abstract
Quantum computer design is a registration that utilises quantum-mechanical wonder, like superposition and entrapment, used to arrange the assets of a quantum computer. A deliberate layered system can be planned to handle the difficulties, which emerge during the advancement of a quantum figuring. The plan usefulness is isolated into layers where the subsystems are planned in such a manner with the goal that it can investigate the issues freely and measures better between the layers bringing about a superior arrangement. Right now, all adaptable quantum figuring innovations are recommendations and critical advances in assembling necessities needed to carry them to the real world. By and by, a few recommendations have less cumbersome innovative obstacles before them than others. Even though its applications are somewhat limited in the construction industry, steps have been taken towards its implementation across the industry as well as other industries.

Abstract
Purpose
This work examines assumptions of positivism and the traditional scientific method.
Design/methodology/approach
Insights from quantum mechanics are explored especially as they relate to method, measurement and what is knowable. An argument is made that how social scientists, particularly sociologists, understand the nature of “reality out there” and describe the social world may be challenged by quantum ideas. The benefits of utilized mixed methods, considering quantum insights, cannot be overstated.
Findings
It is the proposition of this work that insights from modern physics alter the understanding of the world “out there.” Wheeler suggested that the most profound implication from modern physics is that “there is no out there” (1982; see also Baggott, 1992). Grappling with how modern physics may alter understanding in the social sciences will be difficult; however, that does not mean the task should not be undertaken (see Goswami, 1993). A starting point for the social sciences may be relinquishing an old mechanistic science that depends on the establishment of an objective, empirically based, verifiable reality. Mechanistic science demands “one true reality – a clear-cut reality on which everyone can agree…. Mechanistic science is by definition reductionistic…it has had to try to reduce complexity to oversimplification and process to statis. This creates an illusionary world…that has little or nothing to do with the complexity of the process of the reality of creation as we know, experience, and participate in it” (Goswami, 1993, pp. 64, 66).
Research limitations/implications
Many physicists have popularized quantum ideas for others interested in contemplating the implications of modern physics. Because of the difficulty in conceiving of quantum ideas, the meaning of the quantum in popular culture is far removed from the parent discipline. Thus, the culture has been shaped by the rhetoric and ideas surrounding the basic quantum mathematical formulas. And, over time, as quantum ideas have come to be part of the popular culture, even the link to the popularized literature in physics is lost. Rather, quantum ideas may be viewed as cultural formations that take on a life of their own.
Practical implications
The work allows a critique of positivist method and provides insight on how to frame qualitative methodology in a new way.
Social implications
The work utilizes popularized ideas in quantum theory: the preeminent theory that describes all matter. Little work in sociology utilizes this perspective in understanding research methods.
Originality/value
Quantum insights have rarely been explored in highlighting limitations in positivism. The current work aims to build on quantum insights and how these may help us better understand the social world around us.

Abstract
Purpose
This paper aims to examine whether the instructional message used to introduce game-based learning (GBL), prior knowledge, flow and prior gaming experience have an impact on secondary students’ learning outcomes, perceived game utility and motivation to use the game.
Design/methodology/approach
Fifty-four 9th grades students enrolled in this quasi-experimental study. Both groups played the same game. The experimental group was told that they would be playing a game, whereas the control group was told that they would be doing an exercise. The game was designed to promote knowledge recall about familiar mathematical concepts. Prior knowledge was assessed. An immediate and a two-days delayed post-evaluated learning outcomes. Flow, prior gaming experience, perceived game utility and motivation to use the game were assessed with questionnaires after playing.
Findings
Introducing the GBL activity as a game increased immediate learning outcomes for low knowledgeable students, but these benefits did not extend to longer term. Indeed, when the GBL activity was presented as an exercise, low higher knowledgeable students obtained poorer longer-term learning outcomes than more knowledgeable ones, whereas no difference appeared when the GBL was introduced as an exercise. Prior gaming experience and the type of instructional message used to introduce a GBL activity positively influenced perceived game utility and motivation to use the game.
Originality/value
This study is the first to highlight that the way a GBL activity is framed affects differently low and higher knowledgeable students’ learning outcomes and influences perceived game utility and motivation to use the game.

This study aims to examine how fairness concerns and power structure in dyadic green supply chains impact retail price, supply chain profits and greening level decisions.
Abstract
Purpose
This study aims to examine how fairness concerns and power structure in dyadic green supply chains impact retail price, supply chain profits and greening level decisions.
Design/methodology/approach
This study develops game-theoretic models considering fairness concerns and asymmetric power structures under an iso-elastic demand setting. The research paper employs the Stackelberg game approach, taking into consideration the fairness concern of the channel leader.
Findings
The findings indicate that under fairness, there is an increase in both wholesale and retail prices, as well as greening expenditures. Notably, when comparing the two models (manufacturer Stackelberg and retailer Stackelberg), double marginalization is more pronounced in the retailer Stackelberg setup than in the manufacturer Stackelberg setup. In a traditional supply chain with iso-elastic demand, the follower typically extracts higher profit compared to the leader; however, our results show that, under fairness conditions, the leader achieves higher profit than the follower. Additionally, our study suggests that supply chain coordination is unattainable in a fairness setup. This paper provides insights for managers on the optimal supply chain structure and the level of fairness to maximize profit.
Originality/value
This paper investigates the impact of a leader's fairness on the optimal decisions within a green supply chain, an area that has received limited attention previously. Additionally, the study investigates how fairness concerns manifest in distinct power dynamics, specifically, in the contexts of manufacturer Stackelberg and retailer Stackelberg.

Abstract
Purpose
This paper proposes a model based on minority game (MG) theory to support the decision-making regarding the efficient allocation and exploitation of resources/services among the partners of a cloud manufacturing (CMfg) system. CMfg system is a new manufacturing paradigm to share manufacturing capabilities and resources on a cloud platform. The use of a decision model to organize and manage the resources and services provided by the autonomous participants of a CMfg has crucial relevance for the system's effectiveness and efficiency.
Design/methodology/approach
This research proposes a noncooperation model based on MG theory. The MG is designed to make decisions on the use of resources/services among the partners of CMfg with private information. A simulation environment was developed to test the efficiency of the proposed decision model. Moreover, an ideal decision model with complete information among the partners was used as a benchmark model.
Findings
The simulation results show how the application of the proposed MG model outperforms the MG model usually proposed in the literature. In particular, the proposed decision model based on private information has an efficiency closer to the ideal model with complete information among the partners of a CMfg.
Originality/value
This paper advances knowledge about the application of MG in the field of CMfg system. The proposed decision-making model based on MG is a promising approach to help enterprises, and especially small and medium enterprises, to participate in CMfg initiatives and to develop their business.
