In this thesis we present two logical systems, $\bf MP$ and $\MP$, for the purpose of reasoning about knowledge and effort. These logical systems will be interpreted in a spatial context and therefore, the abstract concepts of knowledge and effort will be defined by concrete mathematical concepts.

We study the topological models of a logic of knowledge for topological reasoning, introduced by Larry Moss and Rohit Parikh (1992). Among our results is the confirmation of a conjecture by Moss and Parikh, as well as the finite satisfiability property and decidability for the theory of topological models.

The purpose of this article is to introduce a class of distance-based iterated revision operators generated by minimizing the geodesic distance on a graph. Such operators correspond bijectively to metrics and have a simple finite presentation. As distance is generated by distinguishability, our framework is appropriate for modelling contexts where distance is generated by threshold, and therefore, when measurement is erroneous.

This paper presents a bimodal logic for reasoning about knowledge during knowledge acquisitions. One of the modalities represents (effort during) non-deterministic time and the other represents knowledge. The semantics of this logic are tree-like spaces which are a generalization of semantics used for modeling branching time and historical necessity. A finite system of axiom schemes is shown to be canonically complete for the formentioned spaces. A characterization of the satisfaction relation implies the small model property and decidability for this system.

Tolerance spaces are sets equipped with a reflexive, symmetric, but not necessarily transitive, relation of indistinguishability, and are useful for describing vagueness based on error-prone measurements. We show that any tolerance space can be embedded in one generated by comparisons using prototypical objects. As a result propositions, definable on a tolerance space can be translated into propositions behaving classically.

We present a method for relevance sensitive non-monotonic inference from belief sequences which incorporates insights pertaining to prioritized inference and relevance sensitive, inconsistency tolerant belief revision. Our model uses a finite, logically open sequence of propositional formulas as a representation for beliefs and defines a notion of inference from maxiconsistent subsets of formulas guided by two orderings: a temporal sequencing and an ordering based on relevance relations between the putative conclusion and formulas in the sequence. The relevance relations are ternary (...) (using context as a parameter) as opposed to standard binary axiomatizations. The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs. In doing so, it provides a finitely presented formalism and a plausible model of reasoning for automated agents. (shrink)

We show that Gabbay’s nonmonotonic consequence relations c an be reduced to a new family of relations, called entrenchment relations. Entrenchment relations provide a direct generalization of epistemic entrenchment and expectation ordering introduced by G ̈ardenfors and Makinson for the study of belief revision and expectation inference, respectively.

The purpose of this paper is to introduce a form of update based on the minimization of the geodesic distance on a graph. We provide a characterization of this class using set- theoretic operators and show that such operators bijectively correspond to geodesic metrics. As distance is generated by distinguishability, our framework is appropriate in contexts where distance is generated by threshold, and therefore, when measurement is erroneous.

A central concept for information retrieval is that of similarity. Although an information retrieval system is expected to return a set of documents most relevant to the query word(s), it is often described as returning a set of documents most similar to the query. The authors argue that in order to reason with similarity we need to model the concept of discriminating power. They offer a simple topological notion called resolution space that provides a rich mathematical framework for reasoning with (...) limited discriminating power, avoiding the vagueness paradox. (shrink)

This paper presents an axiomatization of a class of set-theoretic conditional operators using minimization of the geodesic distance defined as the shortest path generated by the accessibility relation on a frame. The objective of this modeling is to define conditioning based on a notion of similarity generated by degrees of indistinguishability.

Larry Moss and Rohit Parikh used subset semantics to characterize a family of logics for reasoning about knowledge. An important feature of their framework is that subsets always decrease based on the assumption that knowledge always increases. We drop this assumption and modify the semantics to account for logics of knowledge that handle arbitrary changes, that is, changes that do not necessarily result in knowledge increase, such as the update of our knowledge due to an action. We present a system (...) which is complete for subset spaces and prove its decidability. (shrink)

Rational inference relations were introduced by Lehmann and Magidor as the ideal systems for drawing conclusions from a conditional base. However, there has been no simple characterization of these relations, other than its original representation by preferential models. In this paper, we shall characterize them with a class of total preorders of formulas by improving and extending G ̈ardenfors and Makinson’s results f or expectation inference relations. A second representation is application-oriented and is obtained by considering a class of consequence (...) operators that grade sets of defaults according to our reliance on them. The finitary fragment of this class of consequence operators has been employed by recent default logic formalisms based on maxiconsistency. (shrink)

We introduce a simple generalization of Gardenfors and Makinson’s epistemic entrenchment called partial entrenchment. We show that preferential inference can be generated as the sceptical counterpart of an inference mechanism defined directly on partial entrenchment.

We introduce a class of set-theoretic operators on a tolerance space that models the process of minimal belief contraction, and therefore a natural process of iterated contraction can be defined. We characterize the class of contraction operators and study the properties of the associated iterated belief contraction.

This paper proposes a formalization of conditional reasoning using Moss and Parikh’s logic of subsets so that a reasoner can express both conditional assertions about beliefs, as well as beliefs about conditional assertions. We present a complete axiomatization of the logic and show that it is decidable. A version of the Ramsey test is found to be compatible with this logic and provides a correspondence between conditionals and belief contraction.

Graphs are employed to define a variety of distance-based binary merging operators. We provide logical characterization results for each class of merging operators introduced and discuss the extension of this approach to the merging of sequences and multisets.

We pursue an account of merging through the use of geodesic semantics, the semantics based on the length of the shortest path on a graph. This approach has been fruitful in other areas of belief change such as revision and update. To this end, we introduce three binary merging operators of propositions defined on the graph of their valuations and we characterize them with a finite set of postulates.

Responsible research and innovation (RRI) is a governance framework promoted by influential policy makers such as the European Commission and academics from the fields of science and technology studies and management. This book is the first text to serve industry. Inspired by existing Corporate Responsibility standards and principles, it offers a selection of tools that can assist practitioners in implementing RRI in business and industry. -/- Responsible Research and Innovation (RRI) is integrative. It is a convergence of Technology Assessment (TA) (...) and Ethics, including corporate responsibility. The task of linking RRI to existing frameworks has only just begun. This book is a welcome example, showing how Corporate Responsibility tools can drive the implementation of RRI. Prof. Armin Grunwald, Head of the Office of Technology Assessment at the German Bundestag and Head of the Institute for Technology Assessment and Systems Analysis, Karlsruhe Institute of Technology, Germany. -/- This is a simple, short, yet encyclopaedic work designed to help business implement RRI using the many tools of Corporate Responsibility (CR) already in place, everything from ISO9001 to the Ceres Roadmap for Sustainability. It makes clear the ways in which RRI is an extension of ideas already well-developed in CR. I learned a lot reading it.

This paper analyses the role of external pressures, internal motivations and their interplay, with the intention of identifying whether they drive substantive or instead symbolic implementation of ISO 14001. The context is one of economic crisis. We focus on Greece, where the economic crisis has weakened the country’s institutional environment, and analyse qualitatively new interview data from 45 ISO 14001 certified firms. Our findings show that weak external pressures can lead to a symbolic implementation of ISO 14001, as firms can (...) defend their legitimacy without incurring the costs of internalization in the local market; weak external pressures can lead to substantive implementation of ISO 14001 when firms have strong internal motivations seeking to strategically differentiate from competitors in international markets. Firms internalize ISO 14001 so as to restore their legitimacy and reputation in foreign markets and stimulate their competitiveness; and strong internal motivations pave the way for companies to stimulate their competitiveness by enhancing their efficiency, as some companies might strengthen their position in the local market by implementing ISO 14001 substantively. The contribution of this paper to the literature on ISO 14001 internalization lies in refining existing theory on the importance of internal motivations for the substantive implementation of ISO 14001 in the context of economic crisis. In addition, this paper extends current theory by challenging studies that dismiss the importance of external pressures. We argue that the intensity of external pressures influences the internalization of ISO 14001, but propose that this relationship might not be linear. (shrink)

Over every and each sport event, a dark veil spreads and obfuscates the celebration: doping. Although anti-doping policies have been widely applied, controlling and diminishing this phenomenon has not been achieved yet and the use of doping is commonplace. In this article, I propose the concept of narcissistic civilization as a tool to interpret this phenomenon. I seek for a parallel reading between the Freudian idea of narcissism and its extension to social narcissism by Fromm, together with Heidegger’s analysis of (...) technology, keeping in mind that doping is a technological application. In this way I point out that both theories share a common view in that humans tend to fail in the distinction between the external reality as an object and their own self as the interpreter, that is between the ¨I¨ and the ¨not I¨. By making this fusion of the two theories that originate from different intellectual traditions, I aspire to provide an interpretation tool for the broad use of doping: I conclude that doping can be understood with the assumption of a narcissistic civilization, focused on technology, that calls for the use of PEDs.

Paternalism is the restriction of a person's autonomy for the good of that person. It embodies a familiar conflict of intuitions: while we cherish individual freedom, we also want to protect/promote what we know to be good. So, every paternalist must meet two challenges: paternalism must be justifiable as a restriction of autonomy as well as effective in terms of well-being. In this essay, I argue that the ‘autonomy’ restricted by paternalism is a Razian brand of free self-authorship and that (...) the ‘good’ protected is captured by Martha Nussbaum's account of personal well-being. I then defend a mild welfare paternalism based on a dichotomy implicit in any defensible description of well-being. I argue that some aspects of the good life do not require endorsement and, therefore, can be justifiably and effectively promoted by autonomy-restricting means. Finally, I discuss why paternalism need not be hostile to ethical independence. (shrink)

ABSTRACT:Existing research on certifiable management standards (CMS) and corporate social responsibility (CSR) tends to focus on large companies and is characterised by disagreement about the role of these standards as drivers of CSR. We contribute to the literature by shifting the analytical focus to the behaviour of small and medium-sized enterprises (SMEs) that subscribe to multiple CSR related standards. We argue that, in respect of motive and commitment, SMEs are not as different from large companies as the literature suggests, as (...) they are guided by similar institutional and economic motives. Results, based on ISO 9001, ISO 14001 and OHSAS 18001 certified SMEs in Greece, demonstrate that later adopters are more susceptible to coercive and mimetic motives and are less likely to commit fully to the CMS requirements, while earlier adopters react to normative motives and considerations of internal efficiency gains and tend to carry out CMS requirements with greater diligence.

A paradigm shift in the human chronotoxicity of xenobiotics would study two‐sided desynchronized phenomena of interfacial interactions between cyclic or periodic environmental insults and the endogenous response and recovery profile. These systems‐based networks are under the influence of well‐synchronized biological clocks and their metabolic regulators. This perspective argues in favor of addressing the concept of synchronization in studies involving critical life windows of susceptibility, or circadian rhythms, or 24‐hour (periodic) diurnal rhythms and answering whether these disruptions in synchronization would affect (...) response and recovery or disease phenotypes associated with environmental insults, e.g., xenobiotics. Synchronization or synchrony is defined as the totality of elements that appear during the same time period within a system, including the network of interactions between the system's elements. Desynchronized interfaces during critical life windows or in time‐repeated exposure events would likely lead to initiating a cascade of adverse health effects associated with differentiated disease phenotypes.

We provide a critique of the usual functionalist, cognition-first reading of Aristotle’s theory of emotion and then offer an alternative understanding of Aristotle's theory of cognition and emotion that brings to bear certain biological considerations evidenced in his arguments on the integration of form and matter (hylomorphism) and the hierarchical organization of the biological world. This, of course, does not suggest that we are critical of all varieties of functionalism, but only those which fail to utilize and incorporate findings in (...) neuroscience. One way to help bridge the gap between mind and the physical world is through empirical findings. Based upon our new reading of Aristotle, we identify affinities with contemporary research in the cognitive neuroscience of emotion and developmental research on emotion. (shrink)

ABSTRACT Within the field of Human Resource Management (HRM), it is assumed that people management practices, including teamworking and cultural initiatives, enable knowledge sharing because they encourage employees to work collaboratively. Perhaps less well understood are occasions when such efforts fail to deliver knowledge sharing arrangements. Here we employ the critical realist concept of emergence to situate the introduction of people management practices in support of knowledge sharing, to examine how such efforts create the emergent properties to either share or (...) not to share knowledge. Then we refine the critical realist concept of communicative reflexivity to explain why employees decide to engage or withdraw from collaborative work. By focusing on reflexivity as not just an ‘internal dialogue’ but also as an ‘external conversation’ we demonstrate why the situated circumstances of work interactions is a significant form of mediation between social contexts and practice in support (or not) of knowledge sharing.

AbstractIn the wake of organizational scandals associated with corporate America servant as well as transformational leadership are seen as approaches capable of engendering a type of morality—on the part of leaders and followers—based on shared values, universal moral principles and an orientation towards a pro-social behavior serving the common good. However, recent critiques have highlighted the tendency in the relevant literature to overlook the systemic context within which leadership and followership are situated. Given this oversight this paper re-visits a classic (...) piece of ethnography on corporate America: Robert Jackal’s Moral Mazes. Employing concepts from critical realism fused with insights from studies on management and bureaucracy we analyse the key themes from the book pertaining to the nature of the leader–follower dynamic in shareholder capitalism. The analysis highlights the role of bureaucracy and corporate ideology as key elements shaping leader–follower relationships, encouraging a type of morality associated with guarding self-interest whilst undermining relationality. The influence of the structural and cultural context in which leader–follower relations unfold draws attention to morality as relationally contingent as opposed to an ideal state. (shrink)

We argue that cognitive models can provide a common ground between human users and deep reinforcement learning (Deep RL) algorithms for purposes of explainable artificial intelligence (AI). Casting both the human and learner as cognitive models provides common mechanisms to compare and understand their underlying decision-making processes. This common grounding allows us to identify divergences and explain the learner's behavior in human understandable terms. We present novel salience techniques that highlight the most relevant features in each model's decision-making, as well (...) as examples of this technique in common training environments such as Starcraft II and an OpenAI gridworld.

If we accept the 7th letter as authentic and reliable, a matter that we will not be addressing in this paper, the text that we have in front of us is “an extraordinary autobiographic document”, an autobiography where the “I” as a subject becomes “I” as an object, according to Brisson. The objective of the paper is to examine how we could approach and interpret the excerpt from Plato’s 7th letter regarding the Doric way of life (Δωριστὶ ζῆν). According to (...) Plato, the Sicilian life (Σικελικὸν βίον) that was allegedly a blissful life (βίος εὐδαίμων) would never allow anyone to become virtuous with all these excesses on behalf of the appetitive part of the soul (ἐπιθυμητικόν). In contrast to this specific type of life that is presented as prevalent in the 7th Letter, only Dion used to live virtuously above pleasure and luxury. The “therapy” for this φλεγμαίνουσαν πόλιν of Syracuse is the return to Δωριστὶ ζῆν κατὰ τὰ πάτρια, the return to the Doric way of the forefathers. The phrase Δωριστὶ ζῆν in its context in the 7th Letter is an important one, because it probably shows the significance of adopting the Doric way of life, in order to create the appropriate conditions for a political reform. Examining the guardians who are the ἄριστοι of the ideal city, a class that constitutes the platonic idea of aristocracy in the Republic, we can understand that they receive many important traits from the Doric ideal (especially the educational program). Combining the concept of Δωριστὶ ζῆν with the Doric ideal, we suggest that the Doric model is quite important for the Athenian philosopher functioning as the cornerstone of reform. (shrink)

Plato was a Socrates’ friend and disciple, but he wasn’t the only one. No doubt, Socrates had many followers, however, the majority of their work is lost. Was there any antagonism among his followers? Who succeeded in interpreting Socrates? Who could be considered as his successor? Of course, we don’t know if these questions emerged after the death of Socrates, but the Greek doxography suggests that there was a literary rivalry. As we underlined earlier, most unfortunately, we can’t examine all (...) of them thoroughly due to the lack of their work, but we can scrutinize Xenophon’s and Aristippus’ work. All of them, Plato, Xenophon and Aristippus, presented to a certain extent their ideas concerning education. Furthermore, they have not neglected the matter of gymnastikè, but what is exactly the role of physical education in their work? Are there any similarities or any differences between them? Since, Xenophon and Aristippus (as well as Plato) seem to be in favor of gymnastikè, it is necessary to understand its role. (shrink)
