It is proposed to expand the structure of the intelligent information system with an addition of knowledge-oriented decision support subsystem. The description of an intellectual workplace is given. Based on this, the main procedures of the subsystem are proposed: the creation of a knowledge base and the search for appropriate responses to a given action. The structure and stages of creating a knowledge base based on the analysis of rules set in natural language are described. The advantages (...) of this approach in comparison with the common approaches based on neural networks are substantiated. (shrink)

Episodic memory often is conceptualized as a uniquely human system of long-term memory that makes available knowledge accompanied by the temporal and spatial context in which that knowledge was acquired. Retrieval from episodic memory entails a form of first–person subjectivity called autonoetic consciousness that provides a sense that a recollection was something that took place in the experiencer’s personal past. In this paper I expand on this definition of episodic memory. Specifically, I suggest that (a) the core features (...) assumed unique to episodic memory are shared by semantic memory, (b) episodic memory cannot be fully understood unless one appreciates that episodic recollection requires the coordinated function of a number of distinct, yet interacting, “enabling” systems. Although these systems – ownership, self, subjective temporality, and agency – are not traditionally viewed as memorial in nature, each is necessary for episodic recollection and jointly they may be sufficient, and (c) the type of subjective awareness provided by episodic recollection (autonoetic) is relational rather than intrinsic – i.e., it can be lost in certain patient populations, thus rendering episodic memory content indistinguishable from the content of semantic long-term memory.

Human knowledge is a phenomenon whose roots extend from the cultural, through the neural and the biological and finally all the way down into the Precambrian “primordial soup.” The present paper reports an attempt at understanding this Greater System of Knowledge (GSK) as a hierarchical nested set of selection processes acting concurrently on several different scales of time and space. To this end, a general selection theory extending mainly from the work of Hull and Campbell is introduced. The (...) perhaps most drastic change from previous similar theories is that replication is revealed as a composite function consisting of what is referred to as memory and synthesis. This move is argued to drastically improve the fit between theory and human-related knowledge systems. The introduced theory is then used to interpret the subsystems of the GSK and their interrelations. This is done to the end of demonstrating some of the new perspectives offered by this view.

In lieu of an abstract, here is a brief excerpt of the content:Martin Heidegger and OntologyEmmanuel Levinas (bio)The prestige of Martin Heidegger 1 and the influence of his thought on German philosophy marks both a new phase and one of the high points of the phenomenological movement. Caught unawares, the traditional establishment is obliged to clarify its position on this new teaching which casts a spell over youth and which, overstepping the bounds of permissibility, is already in vogue. For once, (...) Fame has picked one who deserves it and, for that matter, one who is still living. Anyone who has studied philosophy cannot, when confronted by Heidegger’s work, fail to recognize how the originality and force of his achievements, stemming from genius, are combined with an attentive, painstaking, and close working-out of the argument—with that craftsmanship of the patient artisan in which phenomenologists take such pride. In this study, it is important for us to understand, above all, the true intentions of our author, to illuminate what he thinks really needs to be said, and to surmise what is most critical for him.To get to the heart of Heidegger’s system, it seems fitting to begin with a problem that is generally familiar. We choose the problem of knowledge, a deeper understanding of which takes us to the very threshold of Heidegger’s thought. For this problem, central to modern philosophy, is one of the main obstacles of modern philosophy that Heidegger wishes to surmount. Neo-Kantianism, which takes knowledge as the philosophical problem of the first rank, is the movement against which Heidegger rebels with all his strength. We have, thus, every chance of gaining access to his thought by the main door, so to speak. Once inside the system we will try to trace its outlines, 2 reserving, for a second part of our work, the determination of Heidegger’s place in the history of ideas, especially in the phenomenological movement, as well as of his relations with the philosopher to whom he owes so much—Edmund Husserl. 31In its most general form, the problem of the theory of knowledge has a critical significance. It consists in delineating a domain where knowledge can be certain and in determining the criteria for the legitimate scope of knowledge. But this problem, as normal and as simple as it may appear, has deeper roots. That knowledge should need a criterion at all presupposes that truth is not identical to all that is known and that the course [End Page 11] of things can fail to correspond with the course of thought. “How does knowledge correspond to being?” is a more profound formulation of the problem of knowledge.But we are not going to touch anymore on the primordial phenomenon that generates the problem. The problem of correspondence between thing and thought presupposes a free activity of thought and its isolation in relation to the object. It is precisely this presupposition which renders their harmony and even their contact problematic. “How does the subject take leave of itself to attain the object?” is what the problem of knowledge, in the last analysis, boils down to. Its true source is thus the concept of “subject” as elaborated by modern philosophy. The cogito presided over the subject’s birth. The cogito was the affirmation of the privileged nature of the subject’s immanent sphere, of its unique place in existence; hence, the cogito was the specificity of the subject’s connection to the rest of reality, the sui generis nature which opens up the passage from immanence to transcendence, the passage from ideas contained in the thinking substance to 4 their “formal existence.”The concept of the subject, understood as a substance having a specific position in the entire domain of being, presents us with difficulties of two kinds. First, how do we understand this leave-taking from the self which the thinking substance brings about and which displays an entirely original aspect? Indeed, we could say that thought, in reaching out toward objects, does not actually take leave of itself, since its objects—considered as ideas and contents of thought—are, in a certain sense, already within it. In order to make sense of this paradox, Descartes... (shrink)

The structure of everyday language implies that knowledge is an object. Like an object, it can be acquired, lost, stored, retrieved, and used. Anything that might be done to an external object could also be done to knowledge. Using concepts from the emerging field of biofunctional cognition, this paper discusses an alternative to the everyday-language framework of knowledge. The central idea is that the biological subsystems that comprise the physical nervous system have the capacity to create (...) in us a live, as opposed to pre-recorded, experience that might be described as intuitive self-awareness. In its various manifestations, this ongoing intuitive self-awareness is what we recognize as the knowledge inside us. There is no storage of knowledge of any kind. Intuitive self-awareness is in a perpetual state of re-creation and change. It serves as a private language with which the individual interacts directly with the subsystems of his/her own nervous system. This is the primary function of intuitive self-awareness &emdash; serving as the vehicle for the private communication between the individual and the individual's nervous system. Intuitive self-awareness has also come to serve, through evolutionary symbolic adaptation, as the foundation for the public language that the individual uses to communicate with other individuals. This is the secondary function of the intuitive self-awareness &emdash; to serve as the vehicle for public communication within social groups in which the individual lives. In this function, intuitive self-awareness externalizes to manifest itself in the form of an indirect code system for public communication. The nonsymbolic and symbolic forms of knowledge enable the organism to extend its internal world to encompass the external world in both its totality and detail. (shrink)

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned (...) future systems will need to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

Having entered into the problem structuring methods, system dynamics (SD) is an approach, among systems’ methodologies, which claims to recognize the main structures of socio-economic behaviors. However, the concern for building or discovering strong philosophical underpinnings of SD, undoubtedly playing an important role in the modeling process, is a long-standing issue, in a way that there is a considerable debate about the assumptions or the philosophical foundations of it. In this paper, with a new perspective, we have explored theory (...) of knowledge in SD models and found strange similarities between classic epistemological concepts such as justification and truth, and the mechanism of obtaining knowledge in SD models. In this regard, we have discussed related theories of epistemology and based on this analysis, have suggested some implications for moderating common problems in the modeling process of SD. Furthermore, this research could be considered a reword of system dynamics modeling principles in terms of theory of knowledge. (shrink)

This paper investigates the formal relationship between two prominent approaches to the logic of belief change. The first one uses the idea of "relational partial meet contractions" as developed by Alchourrón, Gärdenfors and Makinson (Journal of Symbolic Logic 1985), the second one uses the concept of "epistemic entrenchment" as elaborated by Gärdenfors and Makinson (in Theoretical Aspects of Reasoning about Knowledge, M. Y. Vardi, Los Altos 1988). The two approaches are shown to be strictly equivalent via direct links between (...) the underlying formal relations. The paper closes with observations about the application of epistemic entrenchment to simple and iterated revisions. (shrink)

As a reaction to the dominant effect and interpretive authority of the digital, Data Loam combines radical approaches based on positions taken in the international practice of contemporary art. Previously: insistence on indexicality and the instrumental reduction of knowledge. Instead: a new metric that requires play, curiosity, experiment, and risk. As an urgent response to the continually growing flood of information that libraries, search engines, and cultural institutions are exposed to, the authors develop approaches that suggest and permit sensual (...) logic, causal permeability, and new forms of man–machine interaction. Data Loam focuses on the future of knowledge systems in texts about artificial intelligence, cybernetics, and cryptoeconomics – as a means of counteracting end-of-the-world fears. (shrink)

Josiah Royce (1855?1916) was, in addition to being the pre-eminent metaphysician at the turn of the 19th century in the USA, regarded as ?a logician of the first rank?. At the time of his death in 1916, he had begun a substantial and potentially revolutionary project in logic in which he sought to show the connection between logic and ethics, aesthetics, and metaphysics. His system was developed in light of the work of Bertrand Russell and A. B. Kempe and aimed (...) to include Russell's logic as a subsystem. This more comprehensive logic, which Royce called system Σ, brought together an analysis of the character of experience and knowledge with the principles which served to organize interests and direct actions. The result was to be a logical theory framed by ?a profoundly ethical motive as well as a genuinely intellectual one? that would serve as ?a theory of the way in which activities must go on if they go on at all?. This paper examines three stages in the development of Royce's logical system, its relation to the logic of Principia Mathematica, and prospects for its further development. (shrink)

Cognitive semantic studies have shown that our conceptualization of morality is at least partially metaphorical and that our moral cognition is grounded in some fundamental contrastive categories of our embodied experience in the physical environment. It is argued that our moral cognition is built on a moral metaphor system. Within the framework of conceptual metaphor theory, this study aims to examine the spatial subsystem of moral metaphors in English. We set out with five pairs of moral metaphors that involve the (...) following spatial source concepts: HIGH and LOW, UPRIGHT and TILTED, LEVEL and UNLEVEL, STRAIGHT and CROOKED, and BIG and SMALL. These metaphors were found to constitute the spatial subsystem of moral metaphors in Chinese. Our primary goal is to find out if the five pairs of moral–spatial metaphors are manifested in English as well. To that end we collected linguistic data from the Corpus of Contemporary American English and searched Google Images for multimodal evidence. Our finding is that the five pairs of moral–spatial metaphors are applicable in English as they are in Chinese. We also discuss issues related to conceptual metaphor theory. (shrink)

Our treatment of combinatorial sentences differs from the one given by McAloon [18] and gives more natural sentences. The (...) same method give also a combinatorial technique with no use of the cut-elimination theorem which is appropriate to study proof-theoretic strength of subsystems of first order arithmetic and some of their expansions. It was used to analyze iterated reflection principle and system of transfinite induction with a satisfaction class. (shrink)

The fourth industrial revolution will be ushered in by future high technology, and as a result, the world will face new difficulties relating to people, the environment, and profitability. Accordingly, the competitive edge and long-term viability of businesses would depend on the knowledge workers who could overcome these excruciatingly difficult obstacles and have the knowledge and competency to influence the overall performance of any type of company. But managing knowledge workers falls under the purview of human resources, (...) and only effective human resources tools, plans, and procedures can ensure the success of this task. One such tool, which has the capacity and capability to change the whole scenario in an organization's favor, is the human resource information system.

A customized HRIS framework is the result of this structured literature review for managing knowledge and competence. The study presents the content analysis of 48 articles, systematically and purposefully selected for this literature review, published during the past three decades.

Precision medicine and molecular systems medicine (MSM) are highly utilized and successful approaches to improve understanding, diagnosis, and treatment of many diseases from bench-to-bedside. Especially in the COVID-19 pandemic, molecular techniques and biotechnological innovation have proven to be of utmost importance for rapid developments in disease diagnostics and treatment, including DNA and RNA sequencing technology, treatment with drugs and natural products and vaccine development. The COVID-19 crisis, however, has also demonstrated the need for systemic thinking and transdisciplinarity and the (...) limits of MSM: the neglect of the bio-psycho-social systemic nature of humans and their context as the object of individual therapeutic and population-oriented interventions. COVID-19 illustrates how a medical problem requires a transdisciplinary approach in epidemiology, pathology, internal medicine, public health, environmental medicine, and socio-economic modeling. Regarding the need for conceptual integration of these different kinds of knowledge we suggest the application of general system theory (GST). This approach endorses an organism-centered view on health and disease, which according to Ludwig von Bertalanffy who was the founder of GST, we call Organismal Systems Medicine (OSM). We argue that systems science offers wider applications in the field of pathology and can contribute to an integrative systems medicine by (i) integration of evidence across functional and structural differentially scaled subsystems, (ii) conceptualization of complex multilevel systems, and (iii) suggesting mechanisms and non-linear relationships underlying the observed phenomena. We underline these points with a proposal on multi-level systems pathology including neurophysiology, endocrinology, immune system, genetics, and general metabolism. An integration of these areas is necessary to understand excess mortality rates and polypharmacological treatments. In the pandemic era this multi-level systems pathology is most important to assess potential vaccines, their effectiveness, short-, and long-time adverse effects. We further argue that these conceptual frameworks are not only valid in the COVID-19 era but also important to be integrated in a medicinal curriculum. (shrink)

Epistemic interactivism, an aspect of the epistemology of representation, is a cognitive intercourse between the subject and person-object of knowledge that underlies the conception of a person in Esan thought. Traditional theories of representation (especially as presented by Descartes and Locke) separated the subject from the object of knowledge, and classified persons and non-persons as object of knowledge. This separation and classification ignored the cognitive and moral values of persons, disengaged the subject from the world and burden (...) the self with solitude and isolation, and created propositional knowledge that dehumanised the relationship between the subject and person-object of knowledge. Within the theoretical framework of Hegel's epistemic interactivism (meliorated by Bowne's personalism) and Esan epistemology (in African philosophy), this book exposes the epistemic interactivism of Esan thought which unified the subject and person-object of knowledge on cognitive and moral grounds; thus providing adequate basis for personhood and resolving the dehumanised relationship between the subject and person-object of knowledge in the traditional theories of representation. Within the context of epistemic injustices, this book analyses the interactivist epistemology of indigenous Esan thought as an alternative epistemological conception of the person-object of knowledge which resolves the deficiency of the traditional theories of representation.

Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and (...) different approaches to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)

The ISA, based on system theory, is the best way to organize knowledge and exchange it. It depends on defining every system through its boundary, main processes within this boundary, and exchange with the environment through this boundary. It relies upon thermodynamics and information theory and is, therefore, applicable to all kinds of systems, which makes it most suitable for cross-disciplinary investigations and innovation. SD is complex and cross-disciplinary by its very nature and, therefore, the ISA is the (...) best way to investigate its different subsystems. Among the most important subsystems of SD are integrated bio-refineries and bio-fuels, both of which are investigated in this article. (shrink)

The hegemony of Western science, inherent in international development projects, often increases the poverty and oppression of Third World women by pre-empting alternative realities. In African and Asian agrarian societies women grow from 60 to 90% of the food (World Bank, 1989); they hold incredible potential to increase food production. Their ability to operate under more marginal conditions than their male counterparts would seem to indicate that they have developed valuable knowledge— knowledge often generated in response to limited (...) access to the more tangible resources offered by development assistance to male farmers.Recognizing the marginalization of women in the Third World, the Women in Development (WID) network was established during the 1970's to produce knowledge about women, fill in the gaps, and set the record straight. But knowledge creation for these purposes leaves underlying paradigms of Western science-based development unquestioned. Research from a feminist standpoint is used to challenge the objectivity and reliability of EuroAmerican development science. To date, WID has documented and analyzed the causes and consequences of Third World women's oppression with no substantial results to end them. Alternatively, feminist research validates women's perceptions of their reality, helping ordinary people to understand the connections between their experiences and broader social, economic, and political struggles. The paper emphasizes research pursued in order to act, closely linking knowing to doing to promote the emancipation of oppressed groups. A feminist standpoint is used to privilege the perspective of rural women in developing countries and ask: “What are the implications of the standard EuroAmerican approach to science for maximizing the potential contributions of rural women to agricultural development?” Some of these implications are illustrated with examples from on-farm research in Nigeria. To some extent, implications can be addressed by constructing meanings to structure a symbolic framework that includes female farmers and other disadvantaged groups. (shrink)

This article proposes a multidisciplinary alternative framework to the classical model of the diffusion of innovations, to analyze the potential uses of microcomputers for development. The emphasis on the indigenous knowledge systems translates a paradigm shift in the analysis of technology transfer.

Expert systems based on indigenous knowledge can help make this shift possible if they are used (...) to understand the cognitive processes of the indigenous knowledge, rather than to mimic their performance.

In this article, we consider variations of Nuel Belnap’s ‘artificial reasoner’. In particular, we examine cases in which the artificial reasoner is faulty, e.g. situations in which the reasoner is unable to calculate the value of a formula due to an inability to retrieve the values of its atoms. In the first half of the article, we consider two ways of modelling such circumstances and prove the deductive systems arising from these two types of models to be equivalent to (...) Graham Priest’s first-degree entailment with an ‘emptiness’ value and Richard Angell’s analytic containment, making computational interpretations of these systems possible. The Belnap-type semantics for AC bring FDE φ and AC in line with other containment logics in their neighborhood. The second half of the article examines formal questions, such as whether AC admits an analysis along the lines of that given to the related system of William Parry’s system of analytic implication, as suggested by Kurt Gödel and confirmed by Kit Fine. Furthermore, a natural means of extending these systems to languages with an intensional implication connective is investigated. (shrink)

This short paper will discuss the background to the special issue through a consideration of the basic knowledge representation issues in AI. We will briefly introduce the symbolic and sub-symbolic representations which are traditionally associated with AI, before noting the socially constructed views of knowledge with which they are at odds and the techniques for knowledge elicitation which they use. This forms the context against which this special issues sits, highlighting the broad view of knowledge elicitation (...) and representation and the issues that they raise which we feel are important to debate in the discipline. By gathering this set of papers together, we hope to encourage researchers to see the value in differing approaches and to encourage a more synthetic view of the discipline, where contributions and insights from different perspectives may be of use.

The Nyãya philosophy is primarily concerned with the conditions of valid thought and the means of acquiring true knowledge of objects. Its ultimate end, like that of the other systems of Indian philosophy, is liberation-a state of pure existence- which is free from both pleasure and pain. For the attainment of this liberation, a true knowledge of objects is the surest means. Hence the theory of knowledge is the very foundation of the Nyãya system. The Nyãya (...) Theory of Knowledge is the first systematic, critical and comparative treatment of the Nyãya epistemology. It reveals how, as a thorough-going realistic view of the universe, the Nyãya philosophy supplies an important Eastern parallel to the triumphant modern Realism of the West, and contains anticipations of as well as possible alternatives to many contemporary realistic theories. This book is important as much for the correct understanding of ancient Indian philosophy, as for the evaluation of modern Western philosophy. (shrink)

Biodiversity initiatives have traditionally operated within a 'science-first' model of environmental decision - making. The model assumes a hierarchical relationship in which scientific knowledge is elevated above other knowledge systems.

Drawing upon two case studies of biodiversity initiatives in Canada, this paper looks at the role that constructivist conceptions of education play in the (...) integration of alternative knowledge systems in environmental decision - making. In so doing, it argues that the conservation, sustainable use and equitable sharing goals outlined by the Convention on Biological Diversity demand new models of governance which embrace the adaptive management qualities of learning organisations.
