In this paper, we review three influential theories of imagination in order to understand how the dynamics of imagination acts could be modeled using formal languages. While reviewing them, we notice that they are not detailed enough to account for all the mechanisms involved in creating and developing imaginary worlds. We claim those theories could be further refined into what we call the Common Frame for Imagination Acts, which defines a framework that can be used to study the dynamics of (...) imagination using formal languages, and we support our claim by showing how the framework allows to model certain imagination acts step by step. Then, we introduce the Rhombus of Imagination, which is a visual tool that can be used in conjunction with our framework to study the procedural structure of different kinds of imagination acts and identify their dynamic properties.

Imagination has received a great deal of attention in different fields such as psychology, philosophy and the cognitive sciences, in which some works provide a detailed account of the mechanisms involved in the creation and elaboration of imaginary worlds. Although imagination has also been formalized using different logical systems, none of them captures those dynamic mechanisms. In this work, we take inspiration from the Common Frame for Imagination Acts, that identifies the different processes involved in the creation of imaginary worlds, (...) and we use it to define a dynamic formal system called the Logic of Imagination Acts. We build our logic by using a possible-worlds semantics, together with a new set of static and dynamic modal operators. The role of the new dynamic operators is to call different algorithms that encode how the formal model is expanded in order to capture the different mechanisms involved in the creation and development of imaginary worlds. We provide the definitions of the language, the semantics and the algorithms, together with an example that shows how the model is expanded. By the end, we discuss some interesting features of our system, and we point out to possible lines of future work. (shrink)

The increasing challenges faced by organizations have led to numerous studies examining human resource management (HRM) practices, organizational ethical climates and sustainability. Despite this, little has been done to explore the possible relationships between these three topics. This study, based on a probabilistic sample of 6,000 employees from six European countries, analyses how HRM practices with the aim of developing organizational ethics influence the benevolent, principled and egoistic ethical climates that exist within organizations, while also investigating the possible moderating role (...) played by their employees’ perception of corporate sustainability. Findings demonstrate that ability-enhancing practices (i.e. recruiting, selection and training) and opportunity-enhancing practices (i.e. job design, industrial relationships and employee involvement) improve benevolent and principled organizational ethical climates, while motivation-enhancing practices (i.e. performance management, compensation and incentives) rather than being related to these organizational ethical climates, are linked to the egoistic climate. In addition, the perceptions of the company’s employees in terms of corporate sustainability moderate these relationships, by reinforcing the positive relationships of ability-enhancing and motivation-enhancing HRM practices in terms of benevolent and principled ethical climates and by reducing the positive relationships between motivation-enhancing practices and egoistic climate. Specific implications for HRM research, teaching and practice are then advanced and discussed. (shrink)

Imagining is something we use everyday in our lives and in a wide variety of ways. In spite of the amount of works devoted to its study from both psychology and philosophy, there are only a few formal systems capable of modelling it; besides, almost all of those systems are static, in the sense that their models are initially predefined, and they fail to capture the dynamic process behind the creation of new imaginary scenarios. In this work, we review some (...) influential theories of imagination and use their insights to distil an algorithm describing such process. Then, we use this algorithm to define a dynamic logical system built upon on a single-agent epistemic logic that provides the necessary tools to capture how the agent voluntarily creates new imaginary worlds; in other words, our system allows the model to be expanded dynamically at any time as a result of the agent performing an act of imagination. Furthermore, we provide an axiomatization and prove that the system is sound and complete. (shrink)

In this article we describe our approach to understanding wrongdoing in medical research and practice, which involves the statistical analysis of coded data from a large set of published cases. We focus on understanding the environmental factors that predict the kind and the severity of wrongdoing in medicine. Through review of empirical and theoretical literature, consultation with experts, the application of criminological theory, and ongoing analysis of our first 60 cases, we hypothesize that 10 contextual features of the medical environment (...) (including financial rewards, oversight failures, and patients belonging to vulnerable groups) may contribute to professional wrongdoing. We define each variable, examine data supporting our hypothesis, and present a brief case synopsis from our study that illustrates the potential influence of the variable. Finally, we discuss limitations of the resulting framework and directions for future research. (shrink)

Although undergraduate students are exposed to ethical issues through class assignments, discussions, and readings, they typically do not have first hand experience with business dilemmas. Student opinions on ethical standards and behavior in American business have received scant attention in the literature. The purpose of the study is to provide additional information to both educators and organizations about the ethical perceptions of students. Furthermore, the study contrasts student responses to business and community leaders' responses obtained in a prior study conducted (...) by Touche Ross (1988). The findings from this study are based on an opinion survey about ethics in American business, completed by 476 liberal arts and business students attending a private, religiously affiliated college in New York State. The data indicate numerous differences in perceptions between students and business and community leaders. Differences were also found when students were classified by school (Arts & Science versus Business) and by gender. Overall, students appear to place a strong value on education. Students are the source of new entrants to the business world and the foundation for ethical structures being built by organizations. The findings from this study should assist both educators and employers in the development of necessary programs to maximize the ethical potential of their constituents. (shrink)

In response to the grim realities of the present world Jewish thought has not tended to retreat into eschatological fantasy, but rather to project utopian visions precisely on to the present moment, envisioning redemptions that are concrete, immanent, and necessarily political in nature. In difficult times and through shifting historical contexts, the messianic hope in the Jewish tradition has functioned as a political vision: the dream of a peaceful kingdom, of a country to return to, or of a leader who (...) will administer justice among the nations. Against this background, it is unsurprising that Jewish messianism in modern times has been transposed, and lives on in secular political movements and ideologies. The purpose of this book is to contribute to the deeper understanding of the relationship between Jewish thought, utopia, and revolution, by taking a fresh look at its historical and religious roots. We approach the issue from several perspectives, with differences of opinion presented both in regard to what Jewish tradition is, and how to regard utopia and revolution. These notions are multifaceted, comprising aspects such as political messianism, religious renewal, Zionism, and different forms of Marxist and Anarchistic movements. (shrink)

The current training model being used in higher education advocates the acquisition of competences aimed at providing students with all-round training that will enable them to tackle their future work responsibilities effectively. This encompasses a number of different competences, most notably the transversal kind, especially in view of the important role they play in shaping the profile of any professional individual. The active learning methods applied to group work have shown to be the most suitable for achieving these competences. From (...) this perspective, and considering their relevance, we present the results of a study that addresses the perceptions held by students from Education Degrees regarding the extent to which transversal competences are acquired by implementing active learning methods. The students perceive group work as a dynamic that teaches them how to be more self-critical and committed to group-oriented tasks, thus encouraging communication skills, personal relationships and motivation. However, a lesser degree of acquisition has been recorded in other equally important competences. As such, it is necessary to promote these learning methods from the start, carefully designing and planning the curriculum structure as well as the tasks to be performed in order to avoid any negative implications that may arise.

This paper analyses the principles of stable cooperation for stochastic games. Starting from the non-cooperative version of a discounted, non zero-sum stochastic game, we build its cooperative form and find the cooperative solution. We then analyse the conditions under which this solution is stable. Principles of stability include subgame consistency, strategic stability and irrational behaviour proof of the cooperative solution. We finally discuss the existence of a stable cooperative solution, and consider a type of stochastic games for which the cooperative (...) solution is found and the principles of stable cooperation are checked.
