Many types of part-whole relations have been proposed in the literature to aid the conceptual modeller to choose the most appropriate type, but many of those relations lack a formal specification to give clear and unambiguous semantics to them. To remedy this, a formal taxonomy of types of mereological and meronymic part-whole relations is presented that distinguishes between transitive and intransitive relations and the kind of entity types that are related. The demand to use it effectively brings afore new requirements (...) for automated reasoning over a hierarchy of relations. To ensure logically and ontologically correct inferencing over both the class and role hierarchy, the new reasoning service RBox compatibility for Description Logics reasoners is introduced. The proposed combination of formal semantics and the new reasoning service will improve the representation of the application domain when using part-whole relations in conceptual models and ontologies.

Ethics support staff help others to deal with moral challenges. However, they themselves can also experience moral challenges such as issues regarding (breaching) confidentiality when practicing ethics support. Currently there is no insight in these confidentiality issues and also no professional guidance for dealing with them. To gain insight into moral challenges related to Moral Case Deliberation (MCD), we studied a) beliefs and experiences of MCD facilitators regarding breaching confidentiality, b) considerations for (not) breaching confidentiality, and c) needs for an (...) ethics support tool. Data collection consisted of qualitative research methods: six semi-structured interviews; analyses of a) two recorded MCD sessions, and b) a focus group with MCD facilitators. Findings: MCD facilitators mention different conceptions and interpretations of confidentiality and various moral challenges. Questions concerning confidentiality ultimately cause reflections on roles and responsibilities of facilitators. Needs for ethics support vary from seeking advice to procedural and sometimes normative guidance for MCD facilitators. Education for MCD facilitators should focus on developing a concrete tool that stimulates awareness and reflection(skills). (shrink)

Anna Bergqvist claims that Frank Sibley—despite his own claims to the contrary—should be considered a particularist when it comes to aesthetics. In this paper I argue that whilst Sibley does hold many of the views that Dancy advances in his Ethics without Principles , Bergqvist is certainly wrong to present Sibley's position as ‘uncontroversially’ particularist. In fact, the relationship between Sibley's account of judgement in aesthetics and Dancy's ethical particularism serves to highlight several ambiguities involved in the particularist–generalist debate as (...) Bergqvist presents it. (shrink)

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

Chalmers' (2018) meta-problem of consciousness emphasizes unexpected common ground between otherwise incompatible positions. We argue that the materialist should welcome discussion of the meta-problem. We suggest that the core of the metaproblem is the seeming arbitrariness of subjective experience. This has an unexpected resolution when one moves to an interventionist account of scientific explanation: the same interventions that resolve the hard problem should also resolve the meta-problem.

The present paper is an extract from a thesis concerning the debate between bradley and russell on the nature of relations. it concerns only the most general points of interaction - the positive influence of bradley upon russell with respect to psychologism, logic, and constructions; the negative influence: russell's work seen as a reaction to bradley. the intention is to show that bradley was an extremely strong influence in russell's development hardly worthy of the disregard which russell showed him.

It is generally believed that Polybios mistook L. Iunius Pullus (cos. 249) for one of the consuls of 248 B. C. The internal evidence of Polybios’ narrative shows clearly that he knew the correct year of Iunius’ consulship, and inadvertently created a false impression of the date by structuring his account so as to tell the story of the Roman siege of Lilybaeum without interruption, from its inception in 250 to Claudius Pulcher’s defeat at Drepana in the following year. This (...) narrative objective led him to postpone the paragraph (1.52.4-5) detailing the Roman reaction to the disastrous siege operations of 250 and the consular elections for 249 until after his account of Drepana, without considering how such an arrangement could mislead readers two millenia hence.

It is argued that (1) the alleged violation of the auspices by both the Consuls of 249 B. C. did in fact occur and (2) resulted in separate prosecutions directed at each of them; (3) the name ‘Pullius’, reported for one of the plebeian Tribunes that prosecuted P. Claudius Pulcher, is probably authentic; (4) the cognomen of L. Iunius Pullus is not spun out the violation of the auspices attributed to him and his colleague; and (5) the cognomen ‘Pulcher’, first (...) born by the Consul of 249, may actually derive from his drowning of the Chickens.

_ Source: _Volume 53, Issue 2-4, pp 294 - 321 Manuscript London, British Library, Burney 330 contains an anonymous collection of grammatical sophisms, dating in all probability from early 13th-century France or England, and all based on problematic biblical, liturgical or religious propositions. After a presentation of the manuscript and collection, this article examines two analysis tools that are applied in the majority of the sophisms, viz. a distinction between three layers of grammatico-semantic perfection or completeness, and the grammatical and (...) semantic supposition doctrines. It appears that these sophisms pay prominent attention to improper or figurative supposition, but are not intended for highly advanced readers. These preliminary results suggest that the Burney Sophismata Collection constituted an exercise tool to support textbook-based instruction in theological grammar, which was developed by such masters as Peter the Chanter and William de Montibus in the late 12th and early 13th centuries.

Multiple different understandings and uses exist of what granularity is and how to implement it, where the former influences success of the latter with regards to storing granular data and using granularity for reasoning over the data or information. We propose a taxonomy of types of granularity and discuss for each leaf type how the entities or instances relate within its granular level. Such unambiguous distinctions can guide a conceptual modeler to better distinguish between the types of granularity and the (...) software developer to improve on implementations of granularity.

This paper develops the concept of the ‘continuum of destructiveness’ in relation to organizational corruption. This notion captures the slippery slope of wrongdoing as actors engage in increasingly dubious practices. We identify four kinds of individuals along this continuum in corrupt organizations, who range from complete innocence to total guilt. They are innocent bystanders, innocent participants, active rationalizers and guilty perpetrators. Traditional explanations of how individuals move from bystander status to guilty perpetrators usually focus on socialization and institutional factors. In (...) addition to these factors, we propose that the very distance between an act and its ethical consequences (ethical distance) may also play a determining role – if not always in the same way – in the transition process. Having developed this conceptual argument, we conclude with a discussion of managerial and research implications. (shrink)

An essential aspect of conceptual data modeling methodologies is the language’s expressiveness so as to represent the subject domain as precise as possible to obtain good quality models and, consequently, software. To gain better insight in the characteristics of the main conceptual modeling languages, we conducted a comparison between ORM, ORM2, UML, ER, and EER with the aid of Description Logic languages of the DLR family and the new formally defined generic conceptual data modeling language CMcom that is based on (...) DLRifd. ORM, ER, EER, and UML class diagrams are proper fragments of ORM2 and CMcom has the most expressive common denominator with these languages. CMcom simplifies prospects for automated, online, interoperability among the considered languages so that modelers not only can continue using their preferred modeling language yet be compatible with the other ones, but also have a common ground that eases database and software integration based on commonly used conceptual data models.

A recurring problem in conceptual modelling and ontology development is the representation of part-whole relations, with a requirement to be able to distinguish between essential and mandatory parts. To solve this problem, we formally characterize the semantics of these shareability notions by resorting to the temporal conceptual model E RVT and its formalization in the description logic DLRUS.

Unlike identification with keys and reference schemes in ER and ORM, UML uses internal, system-generated, identifiers, with a little-known underspecified option for user-defined identifiers. To increase the ontological foundations of UML, we propose two language enhancements for UML, being formally defined simple and compound identifiers and the notion of defined class, which also have a corresponding extension of UML’s metamodel.

Few ontologies in the ecological domain exist, but their development can take advantage of gained experience in other domains and from existing modeling practices in ecology. Taxonomies do not suffice because more expressive modeling techniques are already available in ecology, and the perspective of flow with its centrality of events and processes cannot be represented adequately in a taxonomy. Therefore, formal ontologies are required for sufficient expressivity and to be of benefit to ecologists, which also enables future reuse. We have (...) created a formal mapping between the software-supported ecological modeling method and software tool STELLA and ontology elements, which simplifies bottom-up ontology development considerably and has excellent potential for semi-automated ontology development. However, the conducted experiments also revealed that ontology development for ecology is close to being part of ecological research that through the formalized representation of the knowledge more clearly points to lacunas and suggestions for further research in ecology.

One of the relations used with granularity is indistinguishability, where distinguishable entities in a finer-grained granule are indistinguishable in a coarser-grained granule. This relation is a subtype of equivalence relation, which is used in the other direction to create finer-grained granules. Together with the notion of similarity, we formally prove some intuitive properties of the indistinguishability relation for both qualitative and quantitative granularity, that with a given granulation there must be at least two granules (levels of granularity) for it to (...) be granular, and derive a strict order between finer and coarser granules. Based on these results, granulation hierarchy is defined as extra assisting structure to augment implementations. (shrink)

A formal theory of the ecological niche is indispensable not only for semantic precision in philosophy to understand and compare it with other meanings of niche, but also when computer scientists and ecologists desire to create interoperable software where one can retrieve the niche of a species and compare their parameters. The proposed model is a more fine-grained description of the ecological niche, including the distinction between its complex concept, the abstract niche (‘fundamental niche’) with its hypervolume in multidimensional space, (...) and its realisations (‘realised niches’). The presented ecological niche may initiate new avenues for research in ecology, particularly concerning the conditions/categories of a hypervolume, as well as further philosophical inquiry and comparison with other niches.

There are various recent efforts to broaden applications of ontologies with vague knowledge, motivated in particular by applications of bio(medical)-ontologies, as well as to enhance rough set information systems with a knowledge representation layer by giving more attention to the intension of a rough set. This requires not only representation of vague knowledge but, moreover, reasoning over it to make it interesting for both ontology engineering and rough set information systems. We propose a minor extension to OWL 2 DL, called (...) rOWL, and define the novel notions of rough subsumption reasoning and classification for rough concepts and their approximations. (shrink)

To address the problems of both structured coordination of linked and modularised ontologies and to query a large dynamic ontology system, we propose a basic granularity framework and a set of functions to query such a granulated system. The granularity framework enforces a constrained and structured modularization. This facilitates automation of both dividing a large body of represented information as well as relinking the pieces. The functions enable basic cross-granular querying in a transparent and scalable way, as they rely on (...) the unambiguous management layer provided by the granularity framework, and are reusable for ontologies represented and stored in different formats.

From the side of modelers and early-adopter industry, interest in reasoning over conceptual models and other online usage of conceptual models is growing. To obtain a more precise insight in the characteristics of the main conceptual modeling languages, we define the (semi-)standardized ORM, ORM2, UML, ER, and EER diagram languages in terms of the new generic conceptual data modeling language CMcom that is based on the DL language DLRifd. CMcom has the most expressive common denominator with these languages. CMcom advances (...) prospects for automated, online, interoperability among diverse conceptual data models and ensures compatibility with and between industrygrade conceptual data modeling languages.

Both the Athenian wrestler and the Florentine clerk, it turns out, demonstrate a persistent concern with the moral problematic--that is, the tendency of human beings to do what they want to do at the cost of that which they ought to do. Both thinkers see man's vulnerability to fortune as a symptom of this tendency, and they agree as to its ultimate cause: the inability of men to accurately weigh that which is present here and now against that which is (...) far removed in time and space. Machiavelli does not part company with Plato until it is time to suggest a remedy. Here he indeed accomplishes a radical innovation--perhaps as radical as was suggested above. Whereas Plato resolves the problematic by founding the soul on that which is, and which is better than and prior to man, Machiavelli supposes that man, starting from scratch, can construct his own foundations. Nonetheless, the Florentine walks a long way with the Athenian before he takes his leave; it may be best, then, to interpret Machiavelli's writing less as a monologue than as a dialogue, the dramatis personae of which include himself and Plato.
