Bhaskar and Bunge on Social Emergence
2009
This article discusses the theories of social emergence developed by Roy Bhaskar and Mario Bunge. Bhaskar's concept of emergent causal power is shown to be ambiguous, and some of the difficulties of his depth-relational concept of social emergence are examined. It is argued that Bunge's systemic concept of emergent property is not only different, but also clearer and more consistent than Bhaskar's concept of emergent causal power. Despite its clarity and consistency, Bunge's definition of the concept of emergent property is shown to be too broad and analytically imprecise for the purposes of an emergentist social ontology. It is argued that Bunge's systemic account of social emergence can b…
Ecosystem Architecture Management in the Public Sector : From Problems to Solutions
2019
Based on our research concerning enterprise architecture (EA) in the Finnish public sector, we discuss how EA concept and tool need to be developed to support government business ecosystem and organization design. Our research context indicates, beyond a federal government or a state one, that even a single municipality, like a city concern, can be perceived as an ecosystem of its sectoral domains, subsidiaries and such. We outline a vision of an overall ontology-based, shared EA repository for the-whole-of-government current state descriptions and specify the central design principles and functional requirements for such a system, illustrating some potential use cases of it. Based on inter…
Watermarking for ontologies
2011
In this paper, we study watermarking methods to prove the ownership of an ontology. Different from existing approaches, we propose to watermark not by altering existing statements, but by removing them. Thereby, our approach does not introduce false statements into the ontology. We show how ownership of ontologies can be established with provably tight probability bounds, even if only parts of the ontology are being re-used. We finally demonstrate the viability of our approach on real-world ontologies.
PRIMO LEVI E LA QUESTIONE DELL’ANIMALITÀ
2020
The approach of man and animal in Levi’s work can lead to some simplifications. We could think of a naturalization operation: man is one of many animals. Or, on the contrary, we could think of a culturalization: the animal is a social being. In reality, the ontological principle on which Levi’s thinking and writing are based is that of analogy. Assuming the hypothesis of the anthropologist Philippe Descola, this essay proposes an analogical reading of Levi. Focusing on a precise story, Censura in Bitinia, I will try to discuss this interpretative hypothesis.
UML Style Graphical Notation and Editor for OWL 2
2010
OWL is becoming the most widely used knowledge representation language. It has several textual notations but no standard graphical notation apart from verbose ODM UML. We propose an extension to UML class diagrams (heavyweight extension) that allows a compact OWL visualization. The compactness is achieved through the native power of UML class diagrams extended with optional Manchester encoding for class expressions thus largely eliminating the need for explicit anonymous class visualization. To use UML class diagram notation we had to modify its semantics to support Open World Assumption that is central to OWL. We have implemented the proposed compact visualization for OWL 2 in a UML style …
Impact of diet-induced obesity on the mouse brain phosphoproteome
2018
Obesity is closely associated to several diseases such as type 2 diabetes, cardiovascular disease, hepatic steatosis, airway disease, neurodegeneration, biliary diseases and certain cancers. It is, therefore, of importance to assess the role of nutrition in disease prevention as well as its effect in the course of such pathologies. In the present study, we addressed the impact of the exposure to different obesogenic diets in the mice brains phosphoproteome. To analyze if the obesity could be able to modify the protein pattern expression of brain neurons, obesity was induced in two different groups of mice. One group of mice was fed with hyperglycemic diet (HGD) and the other one was fed wit…
Semantics driven interaction using natural language in students tutoring
2007
The aim of this work is to introduce a semantic integration between an ontology and a chatbot in an Intelligent Tutoring Systems (ITS) to interact with students using natural language. The interaction process is driven by the use of a purposely defined ontology. In the ontology two types of conceptual relations are defined. Besides the usual relations, which are used to define the domain's structure, another type of relation is used to define the navigation schema inside the ontology according to the need of managing uncertainty. Uncertainty level is related to student knowledge level about the involved concepts. In this work we propose an ITS for the Java programming language called TutorJ…
Polyamine Oxidase 5 loss-of-function mutations in Arabidopsis thaliana trigger metabolic and transcriptional reprogramming and promote salt stress to…
2017
The family of polyamine oxidases (PAO) in Arabidopsis (AtPAO1-5) mediates polyamine (PA) back-conversion, which reverses the PA biosynthetic pathway from spermine, and its structural isomer thermospermine (tSpm), into spermidine and then putrescine. Here, we have studied the involvement of PA back-conversion in Arabidopsis salinity tolerance. AtPAO5 is the Arabidopsis PAO gene member most transcriptionally induced by salt stress. Two independent loss-of-function mutants (atpao5-2 and atpao5-3) were found to exhibit constitutively higher tSpm levels, with associated increased salt tolerance. Using global transcriptional and metabolomic analyses, the underlying mechanisms were studied. Stimul…
Formal ontology and CAD integration with macro parametric approach
2017
ABSTRACTThis paper discusses an ontological integration framework in the context of mereotopological formal ontology and CAD systems. Based on a comprehensive literature review of current design knowledge management and formal ontology research works, the authors propose the integration framework that can incorporate design knowledge with CAD systems. The primary role of mereotopology in this research work is the formal representation of design knowledge for the 3D solid assembly models. Most of the existing research works about design ontology present an abstract form and often require significant additional efforts to be integrated into CAD systems. Thus, this work introduces a formal ont…
Filozofia tu i teraz. Ontologia procesu jako podstawa filozoficznego coachingu
2018
Artykuł zawiera szkic ontologicznych podstaw coachingu filozoficznego – nowej dyscypliny praktycznej, która od roku 2016 stanowi składnik oferty edukacyjnej Uniwersytetu Opolskiego. Jest rozwinięciem idei zawartych w moim tekście Filozofia jako ćwiczenie duchowe – coachingowy model uprawiania filozofii. W drugim paragrafie przedstawiono ontologię Platona z perspektywy filozofii procesu. Widziana z tej perspektywy ontologia Platona jest rodzajem metafizyki doświadczenia – byt nazywany przez Platona „prawdziwym” nie jest rzeczywistością abstraktów, lecz tym, czego doświadczamy w chwilach, gdy rozpoznajemy znaczenie konkretnych sytuacji życiowych w perspektywie Dobra. Filozofia Platona okazuje…
