Both short and long-term video-game play may result in superior performance on visual and attentional tasks. To further these findings, we compared the performance of experienced male video-game players (VGPs) and non-VGPs on a Simon-task. Experienced-VGPs began playing before the age of 10, had a minimum of 8 years of experience and a minimum play time of over 20 h per week over the past 6 months. Our results reveal a significantly reduced Simon-effect in experienced-VGPs relative to non-VGPs. (...) However, this was true only for the right-responses, which typically show a greater Simon-effect than left-responses. In addition, experienced-VGPs demonstrated significantly quicker reaction times and more balanced left-versus-right-hand performance than non-VGPs. Our results suggest that experienced-VGPs can resolve response-selection conflicts more rapidly for right-responses than non-VGPs, and this may in part be underpinned by improved bimanual motor control.

The development of access rights as, perhaps, a replacement for copyright in digital rights management (DRM) systems, draws our attention to the importance of ‚the balance problem’ between information industries and the individual user. The nature of just what this ‚balance’ is, is often mentioned in copyright writings and judgments, but is rarely discussed. In this paper I focus upon elucidating the idea of balance in intellectual property and propose that the balance concept is not only the most feasible way (...) to examine whether past solutions to copyright problems are fair, but it also provides the ability to predict what will be the better solution for all affected parties. Based upon an envy-free contribution towards predicting the efficient balance, game theory is applied in a novel manner to the DRM problem to infer where and what might be the optimal balance in the debate over the nature of access right.

Truth, consistency and elementary equivalence can all be characterised in terms of games, namely the so-called evaluation game, the model-existence game, and the Ehrenfeucht–Fraisse game. We point out the great affinity of these games to each other and call this phenomenon the strategic balance in logic. In particular, we give explicit translations of strategies from one game to another.

We define balance games, which describe the formation of friendships and enmity in social networks. We show that if the agents give high priority to future profits over short term gains, all Pareto optimal strategies will eventually result in a balanced network. If, on the other hand, agents prioritize short term gains over the long term, every Nash equilibrium eventually results in a network that is stable but that might not be balanced.

The paper presents a set of games of competition between two or three players in which reward is jointly determined by a stochastic biased mechanism and players’ choices. More specifically, a resource can be found with unequal probabilities in one of two locations. The first agent is rewarded only if it finds the resource and avoids being found by the next agent in line; the latter is rewarded only if it finds the former. Five benchmarks, based on different psychological and (...) game-theoretic assumptions are derived and their predictions compared to actual behavior of 120, 40, and 48 participants playing repeatedly. Of the five benchmarks—the unique (Nash) equilibrium, reinforcement learning, trust-based efficiency, maximum unpredictability, and regret-based (Impulse Balance) equilibrium—regret for missed opportunities best accounts for the qualitative aspect of participants’ behavior and regret attenuated by randomization best accounts for the quantitative aspect of behavior.

In lieu of an abstract, here is a brief excerpt of the content:Game ChangeMaximo CortezOn November 17, 1983, I was born with a condition called mixed gonadal dysgenesis, and ambiguous genitalia. My gender was not of a big concern at that time. The more urgent matter was that I had a heart murmur, which was repaired when I was twelve months old. [End Page E5]It was not until I turned five, and by issue of the Texas Children’s Protective Services (...) (CPS), that my mother was forced to authorize providers to perform normalization surgeries on me. An anonymous caller tipped the CPS that my mother was raising a boy as a girl. The state intervened and explained to my mother that she would have to consent to these surgeries or else she would lose custody of me. This included a gonadectomy and a clitorectomy. Without any consent, these surgeries were performed “in my best interests.” My mother was an epileptic, Hispanic, Mormon, single parent.I was raised to be a socially acceptable female, though as early as five, I played with “boy” toys and enjoyed TV programs aimed at male youth, like Teenage Mutant Ninja Turtles. It was not until I had those normalization surgeries performed on me that I felt different. I knew that something major had happened to me. I woke up in a hospital bed in a gown. I raised the covers and noticed that I had an “X” carved in my groin area. Doctors mutilated my clitoris by reducing its size, which made me feel alienated and angry that something was wrong with my body.I had a surgery performed on me that was to be kept secret and never talked about. This sense of fear and shame was instilled in me shortly after the surgery. I do not recall any psychological evaluations or counseling to help me cope with such surgeries. Seeing everyone else my age going through puberty during my teenage years, I felt behind. I wasn’t becoming a boy with a deep voice or facial hair. Instead, I visited the doctor’s office with my mom and was told that I would be taking oral estrogen to become a woman. I wasn’t until that moment that I understood I was seeing a doctor to foster the development of female secondary characteristics. I felt betrayed by the medical community and by my own mother.Just a few years later, I saw a urologist to find out whether I was ready for a vaginal construction surgery (vaginoplasty). Thankfully the urologist suggested that I was not ready to move forward with an invasive and irreversible vaginal construction surgery. I never pursued it as an adult, as I have always felt male gendered.Social sexual relationships have always been difficult for me but more so with my attraction to women. I first realized my attraction to women in early middle school. Being raised Mexican and a Mormon and knowing that I was homosexual created a lot of conflict for me. I felt that I was a male–gendered person forced into a castrated, mutilated, and medically created female body. I suffered through depression from an early age and it continues today. My conservative Mormon upbringing brought me much shame. The Mormon religion, as most people understand it, expresses a great intolerance to homosexuals and transgender people. I felt like I was a heterosexual male in a female’s body, but the Mormons would never accept me.My later teenage years and mid–twenties were a dark time in my life. I even attempted suicide in my early twenties. My depression was treated with antidepressants and talk therapy. Once I began testosterone, I gradually stopped taking antidepressants. When I was only on estrogen, I felt very moody, angry, and in an emotional funk. I would cry easily and would become very irritable and emotional without cause. With testosterone therapy, I began to think more clearly, had balanced emotions, and began to think more logically.I began to research intersex online and found a women’s androgen insensitivity (AIS) support group. At one of their national conferences, I met another intersex individual who was raised as a female and who had transitioned to male. Like me... (shrink)

Construction is one of the most dangerous industries because of its open working environment and risky construction conditions. In the process of construction, risk events cause great losses for owners and workers. Most of the risk events are closely related to unsafe behaviors of workers. Therefore, it is of great significance for contractors to establish management measures, e.g., incentive and punishment mechanism, to induce workers to reduce unsafe behaviors. This paper aims to take the incentive and punishment mechanism into consideration (...) and develop an evolutionary game model to improve the effectiveness of safety management. The evolutionary stability strategies which can help reduce unsafe behaviors are obtained and analyzed. Results show that there are 12 equilibrium strategies under the condition of different parameters. Specifically, the incentive and punishment mechanism has played an important role for the evolution direction. A balanced incentive and punishment mechanism for the investment and positive stimulus for workers can effectively promote both sides to take positive behaviors, and then realize good evolutionary stable situations. In addition, the initial perceptions of both sides have a decisive impact on the evolution direction. Strengthening communication with the mutual trust between both sides can improve safety performance of both sides. This study is valuable for contractors to design appropriate incentive and punishment measures and establish relevant strategies to promote safe behaviors of construction workers. (shrink)

We find suggestive evidence that emotional balance has an impact on probability weighting incremental to demographic controls. Specifically, low negative affectivity (implying high emotional balance) tends to be a characteristic of those whose probability weighting functions exhibit lower curvature and more neutral elevation. In other words, emotional balance seems to push people in the direction of normative expected utility theory.

For more than twenty years, Peter Vanderschraaf’s work has combined rigorous game-theoretic analysis, innovative use of (social) scientific method, and normative analysis in the context of the social contract. Vanderschraaf’s work has influenced a significant interdisciplinary field of study and culminated in the publication of his book, Strategic Justice: Convention and Problems of Balancing Divergent Interests (OUP, 2019). Building upon his previous work, Vanderschraaf developed a new theory of justice (justice-as-convention) that, despite a mutual advantage approach, considers the most (...) vulnerable members of society and defends the egalitarian bargaining solution. To advance his theory, Vanderschraaf proposes an account of conventions that updates and systematizes David Lewis’s account of conventions, drawing on contemporary developments in game theory and economics. This topical collection brings together game theorists, philosophers, economists, and political scientists to discuss themes from Vanderschraaf’s work. The collection bridges a gap among disjoint but closely related literatures in game theory, bargaining theory, formal philosophy, rationality, equality, justice, and the social contract in order to advance dialogue among scholars in this rich and growing field of study.

In cooperative Cournot oligopoly games, it is known that the β-core is equal to the α-core, and both are non-empty if every individual profit function is continuous and concave (Zhao, Games Econ Behav 27:153–168, 1999b). Following Chander and Tulkens (Int J Game Theory 26:379–401, 1997), we assume that firms react to a deviating coalition by choosing individual best reply strategies. We deal with the problem of the non-emptiness of the induced core, the γ-core, by two different approaches. The first (...) establishes that the associated Cournot oligopoly Transferable Utility (TU)-games are balanced if the inverse demand function is differentiable and every individual profit function is continuous and concave on the set of strategy profiles, which is a step forward beyond Zhao’s core existence result for this class of games. The second approach, restricted to the class of Cournot oligopoly TU-games with linear cost functions, provides a single-valued allocation rule in the γ-core called Nash Pro rata (NP)-value. This result generalizes Funaki and Yamato’s (Int J Game Theory 28:157–171, 1999) core existence result from no capacity constraint to asymmetric capacity constraints. Moreover, we provide an axiomatic characterization of this solution by means of four properties: efficiency, null firm, monotonicity, and non-cooperative fairness. (shrink)

Ender’s Game, Orson Scott Card’s award-winning 1985 novel, has been discovered and rediscovered by generations of science fiction fans, even being adopted as reading by the U.S. Marine Corps. Ender's Game and its sequels explore rich themes — the violence and cruelty of children, the role of empathy in war, and the balance of individual dignity and the social good — with compelling elements of a coming-of-age story. Ender’s Game and Philosophy brings together over 30 philosophers to (...) engage in wide-ranging discussion on issues such as: the justifiability of pre-emptive strikes; how Ender’s disconnected and dispassionate violence is mirrored in today’s drone warfare; whether the end of saving the species can justify the most brutal means; the justifiability of lies and deception in wartime, and how military schools produce training in virtue. The authors of Ender’s Game and Philosophy challenge readers to confront the challenges that Ender’s Game presents, bringing new insights to the idea of a just war, the virtues of the soldier, the nature of childhood, and the serious work of playing games.

We generalize the concept of a cooperative non-transferable utility game by introducing a socially structured game. In a socially structured game every coalition of players can organize themselves according to one or more internal organizations to generate payoffs. Each admissible internal organization on a coalition yields a set of payoffs attainable by the members of this coalition. The strengths of the players within an internal organization depend on the structure of the internal organization and are represented by (...) an exogenously given power vector. More powerful players have the power to take away payoffs of the less powerful players as long as those latter players are not able to guarantee their payoffs by forming a different internal organization within some coalition in which they have more power.We introduce the socially stable core as a solution concept that contains those payoffs that are both stable in an economic sense, i.e., belong to the core of the underlying cooperative game, and stable in a social sense, i.e., payoffs are sustained by a collection of internal organizations of coalitions for which power is distributed over all players in a balanced way. The socially stable core is a subset and therefore a refinement of the core. We show by means of examples that in many cases the socially stable core is a very small subset of the core.We will state conditions for which the socially stable core is non-empty. In order to derive this result, we formulate a new intersection theorem that generalizes the KKMS intersection theorem. We also discuss the relationship between social stability and the wellknown concept of balancedness for NTU-games, a sufficient condition for non-emptiness of the core. In particular we give an example of a socially structured game that satisfies social stability and therefore has a non-empty core, but whose induced NTU-game does not satisfy balancedness in the general sense of Billera.

Vietnam tries to respond to changing international situations, while attempting to stay in accordance with its own ambitions. China and the USA, the two superpowers, are the most important partners of Vietnamese strategy, which is determined by these two countries. The most important economic partner and ideological ally is China. But both sides have some serious problems to resolve such as maritime disputes. The situation imposes the need to seek counterbalance, a reliable ally who provides protection for its own interests. (...) So Vietnam looks to balance improved relations with China while seeking deeper and multidimensional relations with the USA. The United States offers many advantages that are attractive to Vietnam. Inevitably, economic ties and new projects e.g. TPP, political, cultural and scientific cooperation make up these advantages. However, the United States can only provide support for the Spratly and Paracel Islands’ dispute and improving cooperative measures in the South China Sea with the presence of U.S. naval vessels and dialogue that assists Vietnam defense. Vietnam has again become an element in the American strategy of pivoting to Asia. (shrink)

Concussion in professional football is a topic that has generated a significant amount of interest for many years, partly due in recent times to the filing of the class-action litigation and the uncapped compensation injury fund and settlement involving 4,500 retired professional players and the National Football League. The proceedings claimed that the NFL, as the governing body of American football, failed in its duty to protect players’ health during their professional playing careers by exposing players to risks of repetitive (...) concussions and actively concealing links to potential long-term consequences. The NFL litigation sharpened the focus on the fundamental regulatory, governance and ethical considerations for football governing bodies, as self-regulated organisations, when governing the delicate balance between the dynamics of contact and collision sports, entertainment and player-health considerations. It also raised questions about public accountability and responsibilities to all levels of the sport through a framework of public health ethics. The NFL litigation and Congressional hearings have led to changes within the NFL and its regulatory and governance responses. A case study of the NFL responses to concussion in the sport of American football can provide insight into concussion regulation. Australian football governing bodies can align their regulatory and governance responses to concussion within their sports with the aim to avoid similar accusations, and circumvent a more coercive form of intervention.

This paper provides an existential analysis of humour as a social virtue in invasion games at the elite sport level. The main argument is that humour in this particular context can be valuable both in the competitive social training environment and in game performance. This is investigated through philosophical and psychological conceptualisations of humour that are used to reveal and analyse the appearance and possible value of a humorous approach in various social situations experienced during invasion games and the (...) associated training situations. It is concluded that humour can help balance and structure the social training environment as well as facilitate creative game performance. On this basis it is suggested that the existential perspectives on humour presented could make a fruitful contribution to talent development in the domain of invasion games. (shrink)

This book synthesizes the game-theoretic modeling of decision-making processes and an ancient moral requirement, called the Golden Rule of ethics (GR). This rule states, "Behave to others as you would like them to behave to you." The GR is one of the oldest, most widespread and specific moral requirements that appear in Christianity, Islam, Judaism, Buddhism, and Confucianism. The book constructs and justifies mathematical models of dynamic socio-economic processes and phenomena that reveal the mechanism of the GR and are (...) based on the concept of Berge equilibrium. The GR can be naturally used for resolving or balancing conflicts, and its "altruistic character" obviously excludes wars, blood-letting, and armed clashes. The previous book of the authors, The Berge Equilibrium: A Game-Theoretic Framework for the Golden Rule of Ethics, covers the static case of the GR. In this book, the dynamic case of the GR is investigated using the altruistic concept of Berge equilibrium and three factors as follows: a) a modification of N.N. Krasovskii's mathematical formalization of differential positional games (DPGs), in view of the counterexamples given by A.I. Subbotin and A.F. Kononenko; b) the method of guiding control, proposed by N.N. Krasovskii; c) the Germeier convolution of the payoff functions of different players. Additionally, the book features exercises, problems, and solution tips collected together in Appendix 1, as well as new approaches to conflict resolution as presented in Appendices 2-4. The book will be of use to undergraduate and graduate students and experts in the field of decision-making in complex control and management systems, as well as anyone interested in game theory and applications.

How do people respond to others' accidental behaviors? Reward and punishment for accidents might be depend on the actor's intentions, or instead on the unintended outcomes she brings about. Yet, existing paradigms in experimental economics do not include the possibility of accidental monetary allocations. We explore the balance of outcomes and intentions in a two-player economic game where monetary allocations are made with a "trembling hand": that is, intentions and outcomes are sometimes mismatched. Player 1 allocates $10 between herself (...) and Player 2 by rolling one of three dice. One die has a high probability of a selfish outcome, another has a high probability of a fair outcome, and the third has a high probability of a generous outcome. Based on Player 1's choice of die, Player 2 can infer her intentions. However, any of the three die can yield any of the three possible outcomes. Player 2 is given the opportunity to respond to Player 1's allocation by adding to or subtracting from Player 1's payoff. We find that Player 2's responses are influenced substantially by the accidental outcome of Player 1's roll of the die. Comparison to control conditions suggests that in contexts where the allocation is at least partially under the control of Player 1, Player 2 will punish Player 1 accountable for unintentional negative outcomes. In addition, Player 2's responses are influenced by Player 1's intention. However, Player 2 tends to modulate his responses substantially more for selfish intentions than for generous intentions. This novel economic game provides new insight into the psychological mechanisms underlying social preferences for fairness and retribution. (shrink)

Unlike other creatures, humans developed the ability to cooperate with genetically unrelated strangers and a tendency to comply with social norms. However, humans deviate from social norms in various situations. This study used the modified ultimatum game to explore why humans deviate from social norms and how their prosocial behavior can be promoted. In Study 1, participants were asked to imagine working with an anonymous counterpart to complete a task and obtain a certain amount of money (e.g., ¥10). The (...) computer divided the money randomly in favor of the participant (e.g., 9:1 or 8:2). Participants should decide whether to accept or reject such a self-benefiting division. In the non-risk condition, an absolutely fair redivision of money would take place if participants reject self-benefiting division (e.g. 5:5 or 6:4). By contrast, in the risk condition, other-benefiting redivision of money (e.g., 1:9 or 2:8) would take place if participants rejected the self-benefiting division. Results involving 40 college students showed the main effect of condition. The frequency of accepting self-benefiting division in the risk condition was higher than that in the non-risk condition. As such, compliance with social norms is based on the preservation of material resources. In Study 2, we used economic or moral rewards to compensate for economic loss following compliance with the norm. Results involving 28 college students revealed a significant effect of compensation. The rewards, including moral praise, effectively decreased selfish choices. These findings extend previous studies on social norm compliance by emphasizing the importance of internal, fairness-based balance between material and moral needs, as well as the role of moral praise in promoting prosocial behavior.

Female leaders continue to face bias in the workplace compared to male leaders. When employees are evaluated differently because of who they are rather than how they perform, an ethical dilemma arises for leaders and organizations. Thus, bridging role congruity and social identity leadership theories, we propose that gender biases in leadership evaluations can be overcome by manipulating diversity at the team level. Across two multiple-source, multiple-wave, and randomized field experiments, we test whether team gender composition restores gender equity in (...) leadership evaluations. In Study 1, we find that male leaders are rated as more prototypical in male-dominated groups, an advantage that is eliminated in gender-balanced groups. In Study 2, we replicate and extend this finding by showing that leader gender and team gender composition interact to predict trust in the leader via perceptions of leader prototypicality. The results show causal support for the social identity model of organizational leadership and a boundary condition of role congruity theory. Beyond moral arguments of fairness, our findings also show how, in the case of gender, team diversity can create a more level playing field for leaders. Finally, we outline the implications of our results for leaders, organizations, business ethics, and society. (shrink)

The problem considered in the paper is whether the stereotype of zerosum games is applicable to present-day discussions on environmental threats. Decision theory could be considered as a tool to substantiate the philosophical notion of rationality of actions and in this aspect, it could be a good methodological instrument of philosophical economics. Decision theory can be used to assess positions in problem situations and predict possible solutions in terms of gains and losses. This can also be applied to human actions (...) in relation to nature. In the paper this theory is used to assess the moral and political validity of the positions of developing countries against the main claims of the forceful countries for unified solutions for protection of the natural environment. Justified solutions in the field of environmental security can be sought only by overcoming the economic and social imbalances and corporate interests. The most justified perspective for international relations and in searching for solutions of present-day social and ecological conflicts is to move from the form of a zero-sum game, in which the powerful countries win and the poor ones invariably lose, to a true non-zero-sum game suitable for implementing cooperative strategies. This type of development can become a reality only on the basis of a new social contract, based on pluralism and balance of interests, on the scale of all humanity. (shrink)

Pathological gaming among adolescents has been reported to hamper the achievement of a balanced life and to threaten the development of social competencies. Despite the increasing social concerns on the adolescent users, however, the mechanism of gaming behavior of adolescents has not been sufficiently examined. This study explored the mechanism of pathological gaming among adolescents from 3-year longitudinal data of 778 Korean adolescent gamers, by analyzing the effects of negative affects on the degree of pathological gaming through the mediation (...) variables based on the stimulus-organism-response framework. Latent class analysis was used to uncover potential risk groups, and through partial least squares-structural equation modeling analysis, the mediation pathways to pathological gaming were compared between the risk group and the non-risk group. The results highlighted the key role of academic stress on the degree of pathological gaming. In the entire group, academic stress primarily increased pathological gaming through self-control. The mediation path of self-control was the most influential result in the risk group. Aggression was the key mediator between loneliness and pathological gaming in the non-risk group. The theoretical and practical implications of the results were discussed. (shrink)

Applied to video games, Csikszentmihalyi’s work on flow evidences that a positive gaming experience is intrinsically self-rewarding and primarily determined by the skill/challenge balance. A multi-layered measure of enjoyment is built to take these components into account. Gamers were asked to report the concentration-enjoyment they experienced during a first-person shooter game, and to better assess the gap between skill and challenge, the challenge enjoyment was also rated. Along with concentration level, concentration enjoyment is used to build a gaming experience (...) typology that accounts for the self-rewarding component. An enjoyment-based challenge mapping is also drawn up, crossing challenge enjoyment and challenge level. The results show that this integrative enjoyment measure strengthens the causal link between challenge and gaming experience. Most importantly, the findings suggest that challenge or concentration-based enjoyment measures outweigh the standard concentration and difficulty measures as they are more likely to ensure a pleasant and positive experience (flow or relaxation) for the gamers. Indeed, regardless of the reported level of challenge, a gamer is more likely to have a positive experience when challenged at a level she perceives as pleasant. This article emphasizes the importance for game publishers of gathering enjoyment-based concentration and challenge assessments to ensure a positive gaming experience and gamers’ commitment.

Why do we seek out and enjoy uncertain success in playing games? Game designers and researchers suggest that games whose challenges match player skills afford engaging experiences of achievement, competence, or effectance—of doing well. Yet, current models struggle to explain why such balanced challenges best afford these experiences and do not straightforwardly account for the appeal of high- and low-challenge game genres like Idle and Soulslike games. In this article, we show that Predictive Processing provides a coherent (...) formal cognitive framework which can explain the fun in tackling game challenges with uncertain success as the dynamic process of reducing uncertainty surprisingly efficiently. In gameplay as elsewhere, people enjoy doing better than expected, which can track learning progress. In different forms, balanced, Idle, and Soulslike games alike afford regular accelerations of uncertainty reduction. We argue that this model also aligns with a popular practitioner model, Raph Koster’s Theory of Fun for Game Design, and can unify currently differentially modelled gameplay motives around competence and curiosity.

A path scheme for a game is composed of a path, i.e., a sequence of coalitions that is formed during the coalition formation process and a scheme, i.e., a payoff vector for each coalition in the path. A path scheme is called population monotonic if a player’s payoff does not decrease as the path coalition grows. In this study, we focus on Shapley path schemes of simple games in which for every path coalition the Shapley value of the associated (...) subgame provides the allocation at hand. Obviously, each Shapley path scheme of a game is population monotonic if and only if the Shapley allocation scheme of the game is population monotonic in the sense of Sprumont (Games Econ Behav 2:378–394, 1990). We prove that a simple game allows for population monotonic Shapley path schemes if and only if the game is balanced. Moreover, the Shapley path scheme of a specific path is population monotonic if and only if the first winning coalition that is formed along the path contains every minimal winning coalition. We also show that each Shapley path scheme of a simple game is population monotonic if and only if the set of veto players of the game is a winning coalition. Extensions of these results to other efficient probabilistic values are discussed. (shrink)

Until recently, as market forces gradually prevailed over government intervention, the contractarian view had emerged as a preferred method of economic governance due to its attractiveness for business. Following the recent collapse of financial markets and the resulting recession, however, this structural form is now being called into question as the calls for more regulation and government intervention increase. In this context, this article revisits the law versus contract debate in the field of corporate law and governance. Following a theoretical (...) framework utilizing elements of game and resource-based theory of the firm, the company is envisaged as a central counterparty in repeated bargains with its stakeholders. It is shown that power dynamics, which are inherent in the repeated bargains between stakeholders and the company, are prone to imbalance rather than balance by causing cumulative increases in the relative power of stronger parties and vicious spirals of relative power loss for weaker ones. This cumulative power imbalance is then reflected in the organizational rent appropriation process, as weaker parties are eventually expropriated by stronger ones. It is therefore argued that since the contractual model is inherently prone to instability, mandatory power-balancing rules are necessary. Such (re)balancing regulation, however, would need to follow a systemic approach because stakeholder and company power is drawn from, and affected by numerous structural arrangements in the legal and economic system.

This article discusses the use of computer-based simulation games to teach business ethics. The current theory of business ethics simulation games (BESGs) is built on two axioms. The first is that BESGs are best used to teach students ethical principles, and the second is that this is best accomplished by presenting students with ethical dilemmas. This article disputes both of these axioms and proposes new theory. The purpose of BESGs, on the new theory, is to induce in students certain thought (...) processes, not to simulate business situations. According to this new theory, simulation games should be designed to induce in players decision-making processes analogous to those of managers and employees confronted with ethically fraught decisions that have no obvious right or wrong answer. These ethical conundrums involve balancing risks to others and benefits for oneself in the course of ordinary, everyday work. This new theory is illustrated by describing a BESG designed by the author and currently used at several colleges and universities. (shrink)

European identity is a complex, multi-faced and inherently imprecise concept relating to a range of socio-political and psychological factors. Addressing this topic in educational practice, particularly with respect to Higher Education students, constitutes a complex and open problem for research. This paper reports on an experimental study designed to explore the effectiveness of the educational game “RUEU?” in supporting university students in understanding the key socio-political issues regarding European identity. Quantitative data regarding Greek university students’ attitudes to European identity, (...) before and after playing the game, were collected. Students’ performance of the game group was compared with that of a control group who explored the same issues about European identity through a tutor-guided discussion. The findings showed that both instructional interventions were effective but in different ways. The participants in the game-based group appeared more attached to the EU after the intervention and moved toward a more balanced description of their Greek and European identity. On the other hand, the students in the control group rated higher what “European identity” and being EU citizen means to them. The findings indicated the potential of game-based interventions to deliver not only academic content but also to promote students’ reflection and influence them at an attitudinal and emotional level.

We investigate the haggling process in bargaining. Using an experimental bargaining game, we find that a first offer has a significant impact on the bargaining outcome even if it is costless to reject. First offers convey information on the player’s reservation value induced by his social preferences. They are most often accepted when they are not above the equal split. However, offers which request much more than the equal split induce punishing counter-offers. The bargaining outcome is therefore critically influenced (...) by the balance of toughness and kindness signalled through the offers made in the haggling phase. (shrink)

We introduce a solution concept for cooperative games with transferable utility and a coalition structure that is proportional for two-player games. Our value is obtained from generalizing a proportional value for cooperative games with transferable utility in a way that parallels the extension of the Shapley value to the Owen value. We provide two characterizations of our solution concept, one that employs a property that can be seen as the proportional analog to Myerson’s balanced contribution property; and a second (...) one that relies on a consistency property.

Although certain recent developments in mendacious political manipulation of public discourse are horrifying to the academic mind, I argue that we should not panic. Charles Peirce’s pragmatist epistemology with its teleological arc, long horizon, and rare balance between robust realism and contrite fallibilism offers guidance to weather the storm, and perhaps even see it as inevitable in our intellectual development. This paper explores Peirce’s classic “four methods of fixing belief”, which takes us on an entertaining and still very pertinent tour (...) through tenacity, authority and a priori speculation to the method of science – the only method which is both public and self-correcting. Although in the West we (mostly) proudly self-conceive as living in a ‘scientific age’, I argue that this is premature. Precisely insofar as we treat the misbehavior of governments as a harbinger of doom, we remain trapped in authoritarian modes of thinking which Peirce identified with medievalism, although modernity is increasingly quickening around us in worldwide information-sharing practices that are shaped entirely by mutual help. With this framework in mind, many tactics of recent media are most helpfully seen as belonging not to a post-truth, but a pre-truth stage of human intellectual development. Advice on this is sought from Plato, who of course also faced a world that was ‘pre-academic’. (shrink)

This paper analyzes the core of cooperative games generated by asymmetric aggregative normal-form games, i.e., games where the payoff of each player depends on his strategy and the sum of the strategies of all players. We assume that each coalition calculates its worth presuming that the outside players stand alone and select individually best strategies. We show that under some mild monotonicity assumptions on payoffs, the resulting cooperative game is balanced and has a non-empty core. Our paper thus (...) offers an existence result for a core notion which is frequently encountered in the theory and applications of cooperative games with externalities. (shrink)

By focusing on players’ relative contributions, we study some properties for values in positive cooperative games with transferable utilities. The well-known properties of symmetry (also known as “equal treatment of equals”) and marginality are based on players’ marginal contributions to coalitions. Both Myerson’s balanced contributions property and its generalization of the balanced cycle contributions property (Kamijo and Kongo Int J of Game Theory 39:563–571, 2010; BCC) are based on players’ marginal contributions to other players. We define relative (...) versions of marginality and BCC by replacing marginal contributions with relative contributions, and examine efficient values satisfying each of the two properties. On the class of positive games, a relative variation of marginality is incompatible with efficiency, and together with efficiency and the invariance property with respect to the payoffs of players under a player deletion, a relative variation of BCC characterizes the proportional value and egalitarian value in a unified manner.

This article reports results of an experiment designed to analyze the link between risky decisions made by couples and risky decisions made separately by each spouse. We estimate both the spouses and the couples’ degrees of risk aversion, we assess how the risk preferences of the two spouses aggregate when they make risky decisions, and we shed light on the dynamics of the decision process that takes place when couples make risky decisions. We find that, far from being fixed, the (...) balance of power within the household is malleable. In most couples, men have, initially, more decision-making power than women but women who ultimately implement the joint decisions gain more and more power over the course of decision making.

Information communication technology is spreading fast and wide. Driven by convenience, it enables people to undertake personal tasks and make decisions more easily and efficiently. Convenience enjoys an air of liberation as well as self-expression affecting all areas of life. The industry for children's toys is a major economic market becoming ever more tech-related and drawn into the battle for convenience. Like any other tech-related industry, this battle is about industry dominance and, currently, that involves networked toys. Networked toys aim (...) to enhance convenience for children and parents alike. Increasingly difficult to resist, these convenient networked devices are also a societal game changer. Neatly nestled in a lacuna juris and surrounded by a lack of clinical evidence, networked toys raise complex ethical issues concerning human development. This article lays bare the regulatory nexus for networked toys and invites ethical thinking to fill the gap to ensure sufficient protection for all human developmental stages. Networked toys not only affect but also might interfere with child development. Therefore, the article initially summarises the four key psychological stages through which the neurological development of the human brain processes. Each of these stages involves vital windows for human development in cognitive, emotional and social dimensions. Missing any of these developmental windows changes an individual human for life. The article then takes a look at the two main legal frameworks protecting the stages of human development which are applicable to networked toys: First, the examination of the human rights framework with its major segments emanating from the fundamental rights to privacy for family and home, to a child's education as well as to personal data reveals the use of current networked toys as a shielded part of parenting which tends to be at odds with privacy and data protection requirements. Second, the product liability framework for toy manufacturers requires evidence-based causality for putting a child's safety at risk. Unfortunately, these legal frameworks fail to offer sufficient protection of the human developmental stages. There is a lacuna juris. Although networked toys involve the risk of negatively impacting human development in every dimension, clinical psychological studies are impossible to acquire as court evidence for product liability because they take too long to provide reliable data while exposing several generations of children to the examined risk in the process. Meanwhile the temptation of convenience continues to drive the industry and consumers of networked toys and devices, which are already impacting children of all age groups. Accepting this phenomenon as an element of cognitive dissonance in society and in science falls far short of an appropriate ethical balance. The need for creating such an ethical balance concerning networked toys is all the more imperative because even if the networked toy industry managed to eliminate all psychological risks for human development and every legal conflict with privacy and security, significant ethical and societal risks of networked toys remain due to inevitable technological bias. Against these mounting changes, it is suggested that only an ethical approach of interdisciplinary research and learning seems most promising to develop an appropriate equilibrium between the complex challenges posed by networked toys and the societal values at stake.

Through a phenomenological study of horse-human relations, this article explores the ways in which, as embodied beings, we live relationally, rather than as separate human identities. Conceptually this challenges oppositional logic and humanist assumptions, but where poststructuralist treatments of these issues tend to remain abstract, this article is concerned with an embodied demonstration of the ways in which we experience a relational or in-between logic in our everyday lives.

We argue that pedagogic authority relies on love, which is misunderstood if seen as a matter of actions and subjects. Love is based not on finite subjects and objects existing in Euclidean space and linear time, but, rather, on the non-finite ontology, space and time of relations. Loving authority is a matter of calling and vocation, arising from the spontaneous and simultaneous call-and-response of a lively relation. We make this argument through a reading of Buber’s I–You relation and Murdoch’ s (...) account of the responsiveness of ascetic discipline. In presenting this analysis, we draw upon a case study from a research project on Australian teachers and students. (shrink)

Prior research suggests brokers do not always act in the best interests of clients, although morally obligated to do so. We empirically investigated this issue focusing on trades executed at best execution price, before and after the introduction of electronic limit-order trading, on the London Stock Exchange. As a result of limit-order trading, the proportion of trades executed at the best execution price for the customer significantly increased. We attribute this to a sustained increase in the liquidity of stocks as (...) a result of limit-order trading, regardless of market capitalisation. We discuss the ethical implications of our findings and conclude that market structures that enhance market competitiveness may help reconcile broker and client interests. (shrink)

This study examined the link between employees’ adult attachment orientations and perceptions of line managers’ interpersonal justice behaviors, and the moderating effect of national culture. Participants from countries categorized as low collectivistic and high collectivistic completed an online survey. Attachment anxiety and avoidance were negatively related to interpersonal justice perceptions. Cultural differences did not moderate the effects of avoidance. However, the relationship between attachment anxiety and interpersonal justice was non-significant in the Southern Asia cultural cluster. Our findings indicate the importance (...) of ‘fit’ between cultural relational values and individual attachment orientations in shaping interpersonal justice perceptions, and highlight the need for more non-western organizational justice research.
