The purpose of this research is to examine the effects of congruence between the ideal self-image of a game player and the game character on identification and interaction with the game character, perceived game power and performance, character attachment and willingness to spend money on the game character.

A total of 347 online game players participated in an online survey posted via the nationwide crowdsourcing web service Mechanical Turk in the US. A structural equation modelling was conducted using a maximum-likelihood estimation procedure to test the relationships among the variables.

The results revealed a significant positive impact of congruence between a game character and the ideal self-image of a game player on identification and interaction with the game character, perceived game power, game performance, attachment to the game character and willingness to spend money on the game character.

Although significant research has been conducted in the area of online gaming, limited attention has been given to the strategic game content that stimulates a player's intention to purchase game items. Due to the challenges in sales growth in the game industry caused by business model shifts from a subscription-based model to a free-to-play one, it is important for marketing practitioners to motivate game players to continue playing the game and purchase game items. The results of this study provide valuable strategic insights to overcome the limitations of existing marketing strategies in the online game business.

The purpose of this paper, drawing mainly on insights from Foucault and Wittgenstein, is to conceptualise intellectual capital (IC) in very generalist terms as both language game and power in order to initiate a critical understanding of IC.

IC is viewed as knowledge about knowledge, knowledge creation and how such processes might be leveraged into value. It is argued that a critical understanding of IC requires a historical, contextual and linguistic understanding of how IC has emerged and how IC is used. Perceiving IC as language game and power is one way of initiating such critical understanding.

IC is perceived as a social construction and the genealogical focus is on how actors, positions and interests influence this process of social construction.

The paper offers concepts and methods that facilitate historical and contextual research on how IC emerges and how IC is used. Further historical studies are necessary in order to reflect upon and improve extant IC concepts and methods

The paper offers a critical understanding of IC by introducing concepts from the organisational discourse literature. Further it offers practical methodological guidelines for conducting critical genealogical research.

The purpose of this paper is to examine the impact of renewable energy on the power supply chain and to study whether the renewable generator or the power grid that purchases power from the power spot market is better when the actual generation of renewable energy is insufficient. The authors want to compare and analyze the different power supply chain operation modes and discuss the optimal mode selection for renewable energy generator and power grid in different situations.

This paper studies the grid-led price competition game in the power supply chain, in which the power grid as a leader decides the price of transmission and distribution, and generators determine the power grid price. The renewable energy power generator and the traditional energy power generator conduct a price competition game; on the other hand, the power grid and power generators conduct Stackelberg games. The authors analyze the power supply of single power generator and two power generators, respectively, and research on the situation that the renewable energy cannot be fully recharged when the actual power generation is insufficient.

The study finds that both renewable and traditional power grid prices decline as price sensitivity coefficient of demand and installed capacity of renewable energy generators increase. Power grid premium decreases as the price sensitivity coefficient of demand increases, but rises as the installed capacity of renewable energy generator increases. When there is a shortage of power, if the installed capacity of renewable energy is relatively small and price sensitivity coefficient of demand is relatively large, the grid purchases the power from power spot market and shares cost with renewable energy generators, leading to higher expected profits of the renewable energy generators. On the contrary, the renewable energy generators prefer to make up power shortage themselves. For the power grid, purchasing the power by the renewable energy generators when there is a power shortage can bring more utility to the power grid when the installed capacity of renewable energy is lower and the demand price sensitivity coefficient is higher. When the installed capacity of renewable energy is high and the price sensitivity coefficient of demand is moderate, or the installed capacity of renewable energy is moderate and the demand price sensitivity coefficient is high, a generator that simultaneously possesses two kinds of energy source will bring more utility to the power grid. If the installed capacity of renewable energy and the demand price sensitivity coefficient both are small or the installed capacity of renewable energy and the price sensitivity coefficient of demand both are large, the power grid prefers to purchase the power by itself when there is a power shortage.

The goal of our paper analysis is to explore the implications of the theoretical model and address the series of research questions regarding the impact of the renewable energy on the power supply chain. The results of this study have key implications for reality. This paper sheds light on the power supply chain operation mode selection, which can potentially be used for the renewable energy generators to choose their operating mode and can also help traditional energy generators and power grid enterprises maximize their utility. This paper also has some references for the government to formulate the corresponding renewable energy development policy.

This paper studies the power operation mode under the uncertainty of supply and demand, and compares the advantages and disadvantages of renewable energy generator that makes up the shortage or the power grid purchases the power from power spot market then shares cost with the renewable energy generator. This paper analyzes the power grid-led coordination problem in a power supply chain, compares and analyzes the price competition game model of single power generator and dual power generators, and compares the different risk preferences of power grid.

Green energy as a transportation supply trend is irreversible. In this paper, a highway energy supply system (HESS) evolution model is proposed to provide highway transportation vehicles and service facilities with a clean electricity supply and form a new model of a source-grid-load-storage-charge synergistic highway-PV-WT integrated system (HPWIS). This paper aims to improve the flexibility index of highways and increase CO₂ emission reduction of highways.

To maximize the integration potential, a new energy-generation, storage and information-integration station is established with a dynamic master–slave game model. The flexibility index is defined to evaluate the system ability to manage random fluctuations in power generation and load levels. Moreover, CO₂ emission reduction is also quantified. Finally, the Lianhuo Expressway is taken as an example to calculate emission reduction and flexibility.

The results show that through the application of the scheduling strategy to the HPWIS, the flexibility index of the Lianhuo Expressway increased by 29.17%, promoting a corresponding decrease in CO₂ emissions.

This paper proposed a new model to capture the evolution of the HESS, which provides highway transportation vehicles and service facilities with a clean electricity supply and achieves energy transfer aided by an energy storage system, thus forming a new model of a transportation energy system with source-grid-load-storage-charge synergy. An evaluation method is proposed to improve the air quality index through the coordination of new energy generation and environmental conditions, and dynamic configuration and dispatch are achieved with the master–slave game model.

The purpose of this study is to propose a decentralized multi-party cross-trading scheme based on a certificate transaction mechanism for the transaction of excess consumption certificates (ECCs) of renewable energy. The aim is to address the problems associated with the existing centralized transaction mode and to promote the development of the green electricity industry.

The proposed scheme involves calculating the quotation difference for the same type of certificate transaction based on the quotations of all users of both buyers and sellers. The transaction volume is then determined based on the order of quotation difference from large to small, and the total interests of cooperation are calculated. The nucleolus method is adopted to allocate the total interests to each member of the alliance and calculate the final transaction price. The blockchain technology is used for the transaction to achieve accurate traceability and efficient supervision, and a corresponding smart contract is designed and simulated in the Ethereum consortium chain.

The results of the simulation show the rationality and effectiveness of the proposed scheme. The decentralized multi-party cross-trading scheme can overcome the problems associated with the existing centralized transaction mode, such as low transaction efficiency, difficulty in obtaining the optimal transaction strategy and efficient supervision. The proposed scheme can promote the development of the green electricity industry by stimulating users' demand potential for green electricity.

The proposed scheme is original in its use of a certificate transaction mechanism to facilitate the trading of ECCs of renewable energy. The scheme adopts a decentralized multi-party cross-trading approach that overcomes the problems associated with the existing centralized transaction mode. The use of the nucleolus method for the allocation of total interests to each member of the alliance is also original. Finally, the use of blockchain technology for accurate traceability and efficient supervision of the transaction is an original contribution to the field.

The purpose of this paper was to gain a better understanding of the nature of online communities, the relationships within them and the relationship between such communities and the host organization. Knowledge sharing via participation in online communities is a central part of many multinational organizations’ business strategies; however, the task is not always straightforward.

The research focused on power relationships in online communities. The approach was inductive and consisted of an exploratory case study using semi-structured interviews, augmented with direct observation and documentary sources, within a framework provided by the French sociologists Crozier and Friedberg.

The findings identify the various reasons for participating in the community and aspects of both the relationships within the community and between the community and the host company.

The research shows that online communities are not easy to categorize and that attempting to use a single solution for the management of such communities risks oversimplifying a complex situation. It also shows that Crozier and Friedberg’s framework is useful in highlighting issues that otherwise might not have been noticed.

Issues of power are often neglected in studies of online communities. The use of Crozier and Friedberg’s framework offers a novel way to examine power relationships, which can offer new insights into how such communities function.

There is a growing trend in higher education institutions to develop multi-disciplinary approaches to education for sustainable development and to implement student-centered and problem-based methodologies to increase student engagement and satisfaction. This paper aims to present an innovative methodology to increase student awareness about the effects of economic decisions on sustainability.

This method uses a videogame and two board games to simulate three spheres of economic interaction, namely, local, national and international. For every sphere, three key economic sectors and their relationships with fundamental sustainable development goals (SDGs) are addressed. This study uses pre- and post-simulation data to analyze the students’ perceptions regarding the usefulness of the simulations and their awareness about the effects of economic decisions on sustainability.

The implementation of this teaching and learning method demonstrated not only that active learning can effectively increase student awareness about the potential social and environmental consequences of economic decisions but also that students perceive games and simulations as useful teaching and learning tools.

Students in these areas need to learn not only how to transform original ideas into successful projects but also to align financial results with social and environmental objectives. The methodology presented in this research allows to enhance learning from a multi-disciplinary perspective, helping the students to analyze different economic sectors and their connection with a number of SDGs through the lens of public economics.

The outbreak of the COVID-19 virus has shown the effects of a global pandemic at the economic, social and environmental levels. This paper presents an innovative active learning framework to increase sustainability awareness among students of economics, business and management.

The purpose of this paper is to demonstrate the implications of power imbalance and over-emphasis on commercial logic on the structure and governance of Scottish football.

An in-depth analysis of secondary sources is used to identify the logics at play in Scottish football and to explore implications of the liquidation of Rangers for the structure of the game.

Over-emphasis on commercial logic has led to power being concentrated in two clubs, Celtic and Rangers, and to other clubs and the league itself becoming financially dependent on those clubs. The collapse of Rangers thus threatened the stability of other clubs and the league. The case highlights the challenge of reconciling competing logics and the role played by previously peripheral actors in bringing about change in the field.

The on-going nature of the case, related investigations and legal process meant that it was not possible to supplement the secondary source material with primary evidence.

It demonstrates the multi-faceted nature of elite contemporary football and of the challenges faced by leagues and governing bodies in accommodating logics and multiple stakeholder interests. It also highlights the need for more effective financial regulation of corporate football clubs and their officials and emphasises the importance of inclusive stakeholder governance.

It highlights the risks inherent in football business in small markets dominated by one or a few clubs. It highlights the role that previously peripheral actors can play in bringing about change within a field.

Games and learning research has diverged into “games for learning” and “games as learning” research. This paper aims to provide a third framing, “games with learning”, that can help address the lived experiences learners have with these media outside of formal, instructional contexts.

This paper is a critical analysis of the current games and learning field, considering what has been missed by recent research in the field and how we might benefit from further consideration of what Bernard Suits calls the “lusory attitude” or voluntary choice to accept inefficiencies in achieving goals. The paper analyzes dominant rhetoric of educational game research, with the intent of revealing the implicit assumptions about play and choice that much recent “games for learning” and “games as learning” work may have ignored.

The paper reveals that the further consideration of learning through extant play with games (characterized here as “games with learning”) can be a means of shifting the direction of educational games research toward investigations of how games are played “in the wilds” of out-of-school contexts. The paper advocates for a shifting of focus from compulsory contexts to the study of voluntary game play.

The paper argues for the complex value of games and gameplay in non-institutional settings, and advocates for further research to understand games in non-institutional spaces.

The key argument is that games and learning to date has focused inordinately on how games can further educational design, rather than how the use of games can reveal important new contexts for learning.
