Ethologists and others studying animal behavior in a spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed to particular Just such an interim descriptive method can be found in intentional system theory. The use of intentional system theory is illustrated with the case of the apparently communicative behavior of vervet monkeys. A way of using the theory to generate data - including usable, testable data - is sketched. The (...) underlying assumptions of this approach can be seen to ally it directly with theorizing in evolutionary biology, which has recently come under attack from Stephen Gould and Richard Lewontin, who castigate it as the Their arguments, which are strongly analogous to B. F, Skinner's arguments against point to certain pitfalls that attend the careless exercise of such thinking (and rival varieties of thinking as well), but do not constitute a fundamental objection to either adaptationist theorizing or its cousin, intentional system theory.

This commentary argues that the anomalies suffered by the population behavior genetics paradigm are more widespread than suggested by Charney, including many made in the field of developmental science. Further, it is argued that, according to the criteria established by Kuhn, there is and has been available an alternative scientific paradigm that provides the formative context for Charney's postgenomic view. This is the relational developmental systems paradigm.

This Agenda 2050 piece is a call to action for management scholars to follow the lead of business associations, foundations, and businesses in studying and understanding the transformative change needed to bring about a more equitable and flourishing world for all living beings—including humans and other‐than‐humans. These entities advocate for a significant paradigm shift in how business is practiced as a way of responding to ‘polycrisis’—the interrelated set of civilization‐threatening crises that includes climate change, social inequality, and biodiversity loss. (...) Yet management scholars lag behind business discourse with issues of sustainability and ecological flourishing, adapting to the type of leadership needed for the future, and understanding the need for system change. We provide four keystone pathways to help scholars shape future discourse in business scholarship, practice, and curricula: 1) structural changes to management education, 2) piloting social impact, 3) development of regenerative business models, and 4) moral, legal, and financial cases for action.

Chapter 1 WHY SYSTEMS PHILOSOPHY? Some reasons, for synthetic philosophy generally The persistent theme of this study is the timeliness and the necessity of ...

The Visual World Paradigm (VWP) presents listeners with a challenging problem: They must integrate two disparate signals, the spoken language and the visual context, in support of action (e.g., complex movements of the eyes across a scene). We present Impulse Processing, a dynamical systems approach to incremental eye movements in the visual world that suggests a framework for integrating language, vision, and action generally. Our approach assumes that impulses driven by the language and the visual context impinge minutely on (...) a dynamical landscape of attractors corresponding to the potential eye-movement behaviors of the system. We test three unique predictions of our approach in an empirical study in the VWP, and describe an implementation in an artificial neural network. We discuss the Impulse Processing framework in relation to other models of the VWP. (shrink)

The article describes two approaches to modeling the concept system of science – the thematic and paradigm ones. The re­search represents a case study of the two corpuses of abstracts: abstracts of projects supported by the Department of Humanities and Social Sciences of the Russian Federal Property Fund in lin­guistics, as well abstracts of articles by authors (and their co-au­thors) who have received multiple support from this foundation. Thematic modeling was carried out within the frameworks of two approaches: сcorpus (...) based approach (modeling the system of concepts as a holistic entity of term fields network), and single text approach (singling out compositions of term fields steadily present in the texts of projects which can be treated as separate branches of linguistics). The method of semantic graph modeling realized in the “Semograph” Information system (corpus based approach) and the K-means clustering method (single text based approach) were applied. Arrays of keywords (those that occurred in the abstracts of projects supported by the Foundation) grouped into term fields served as operational units. Paradigmatic model­ing was based on the analysis of network interaction of research­ers (created on the basis of the information on joint publications). After the hypergraph of researchers (2,108 state points) had been created, it was divided into subgraphs (network communities) by means of the modularity method (analogue of cluster analysis). Each cluster can be considered as a model of a scientific commu­nity that actualize a certain scientific paradigm; a set of clusters represents a model of the concept system of a certain subject domain from the point of view of representation and interrela­tion of several paradigms. The synthesis of thematic and paradig­matic models appears to be the direction for future research that involves modeling the concept system of science. The considered models can be applied as an effective means of monitoring, fore­casting and managing scientific research, i.e. as an instrument of state and/or department policy. (shrink)

Social systems theory has been dominated in recent years by the work of Niklas Luhmann, but there is another strand of systems thinking, which is receiving increasing attention in sociology: emergentism. For emergentism, the core problems of systems thinking are concerned with causation and reductionism; for Luhmann, they are questions of meaning and self-reference. Arguing from an emergentist perspective, the article finds that emergentism addresses its own core problem successfully, while Luhmann's approach is incapable of resolving questions of causation and (...) reductionism. On the other hand, neither paradigm yet has a convincing response to the challenges of meaning and self-reference. Key Words: social systems • emergence • paradigms • autopoiesis • critical realism.

In his insightful review, Eugene V. Koonin discusses various aspects of CRISPR-Cas systems with a strong focus on their qualities as "adaptive immune systems". The CRISPR-Cas system is most famous for its application as a gene-editing tool. Koonin provides a deeper insight into its biological function in bacteria, which is to immunize the cell against parasite DNA. I shall comment on one issue discussed in the text, in two steps. First, I shall elaborate on CRISPR-Cas systems and their supposed Lamarckian (...) character. Criteria for calling biological phenomena genuinely Lamarckian will be narrowed down and then applied to the CRISPR-Cas system, considering interference-driven spacer acquisition as an instantiation of a truly Lamarckian paradigm. Second, I shall consider whether Lamarckian and "canonical" instances of inheritance are a case of theoretical pluralism, being two non-reducible, yet interconnected paradigms. (shrink)

Every scientific or intellectual movement is founded upon basic assumptions and hypotheses that shape its specifically formulated philosophy. This study seeks to explore and explicate the basic philosophical underpinnings of grey systems theory, as well as the paradigm governing its postulates. The study, more specifically, scrutinizes the underlying principles of GST from the perspective of postmodern philosophy. To accomplish this, the epistemology, ontology, human nature, and methodology of GST are substantially investigated in the light of postmodern philosophy. The study (...) draws on Burrell and Morgan’s framework to reveal the paradigm underlying the philosophy of GST. Results demonstrate that GST is an anti-realistic, anti-positivistic, and non-deterministic theory which is inherently pluralistic and ideographic. Based on the principles of GST, change is an indispensable dimension of human speculation about the world and systems, and knowledge is ceaselessly reproduced as new information is collected. As a result, knowledge, narratives, theories and scientific laws are dynamically changed. GST, then, is remarkably compatible with the foundations of postmodern thought and it could be regarded as a postmodern theory governed by a humanistic paradigm. (shrink)

Linguistic Modelling of Scenarios proposes a paradigm change from the 'systemic VIEW' to 'systems SCIENCE', so as to extend the methodology of conventional science of physics into the domains hitherto beyond the reach of this kind of treatment. The book: I. Identifies the problematic issues in current approaches to the 'systemic or structural view' of parts of the world as opposed to the 'quantitative/qualitative views' of conventional science of physics and the arts whereby introducing the 'third culture'. (...) II. Locates the position of the structural view in the context of 'human intellectual endeavour'. III. Discusses the fundamental questions raised by modelling aspects of human behaviour. IV. Introduces the basic ideas and the symbolism of linguistic modelling which are then applied to turning descriptions of scenarios as a story or narrative into reasoning schemes. V. Describes a methodology of 'problem solving' of which design thinking and the operation of purposive systems are seen as essential ingredients. Problem solving is a universal activity of living in particular human beings through innovation, invention and creativity. Lack of this activity leads to death! Problem solving is regarded as pivotal point which may propel the spread of the modified structural view into social, technical, cultural and educational awareness. VI. Shows the location of aspects of conventional science within the scheme of systems science whereby achieving a 'continuity of the scientific endeavour'. VII. Outlines a teaching scheme for 'linguistic modelling'. Janos Korn explains how a view can be converted into a science which can lead to a possibility of 'organised speculation' or simulation of behaviour, exploring the effects of variation of parameters on performance, and the occurrence of outcomes of operations, beneficial or not, of dynamic structures. Static and dynamic structures are expressed in more rigorous and computable terms so that the results of analysis and design of human activity scenarios could be exposed to at least thought experiments. Linguistic Modelling of Scenarios is an informative read for any professionals, teachers and students of engineering, social science, management, business and production. (shrink)

Cloud computing paradigm is growing rapidly, and it allows users to get services via the Internet as pay-per-use and it is convenient for developing, deploying, and accessing mobile applications. Currently, security is a requisite concern owning to the open and distributed nature of the cloud. Copious amounts of data are responsible for alluring hackers. Thus, developing efficacious IDS is an imperative task. This article analyzed four intrusion detection systems for the detection of attacks. Two standard benchmark datasets, namely, NSL-KDD (...) and UNSW-NB15, were used for the simulations. Additionally, this study highlights the proliferating challenges for the security of sensitive user data and gives useful recommendations to address the identified issues. Finally, the projected results show that the hybridization method with support vector machine classifier outperforms the existing techniques in the case of the datasets investigated. (shrink)

Systems thinking is an increasingly recognized paradigm in education in both natural and social sciences, a particular focus being, naturally, in biology. This article argues that plant biology, and in particular, plant hormonal signaling, provides highly illustrative models for learning and teaching in a systems paradigm, because it offers examples of highly complex networks, ranging from the molecular‐ to ecosystem‐scale, and in addition lends itself to the use of real‐life biological objects.

Science is a historically evolved and developed system, which does not include every construction. If a new construction is to become part of scientific knowledge, it must fit into a certain paradigm or meet the conformity princilple and comply with certain general "rules of the game". These two aspects constitute the systemic principle, which thus works as a sort of a metaregulative.

This dissertation elucidates the notion of physical system which opens new conceptual pathways that connect the three realms of physical theory; spacetime, material bodies and their properties, and the laws of nature which govern their evolution. The notion of physical system includes two presuppositions regarding their structure. The first presupposition is a description of isolated systems and their evolution in time, which amounts to a Paradigm of Uniform Motion. The second presupposition describes how parts of a physical system are (...) combined into wholes. This presupposition amounts to a Rule of Composition. Once we make these presuppositions explicit we can derive the spacetime structures and the fundamental equations of motion. "Newtonian" and "relativistic" systems are shown to differ with respect to the paradigm of uniform motion, a difference that leads to the respective structures of Newtonian mechanics and the Special Theory of Relativity. ;The philosophical framework offered in this dissertation provides a new interpretation of the concept of mass, and a new elucidation of the relation between the conservations of mass and momentum. Previous analyses of the concept have claimed that "mass" cannot be defined and broken down to more primitive predicates. The framework offered here, on the other hand, enables the systematic reduction of the concept of mass to motions and the presuppositions we have regarding the nature of physical systems. The new interpretation of mass reveals a surprising connection between mass and inertial reference frames, as they are both shown to be derived, in a similar way, from our definition of physical systems. Mass is by necessity attributed to bodies in virtue of the frame we use to describe their motions. This account also enables us to understand the different conceptual roles of mass and their interconnections. In the context of Newtonian mechanics, the roles of mass as a Quantity of Matter, as the Inertial property of bodies, and as Gravitational mass are shown to be various aspects of a single role the concept has in the new framework offered here. In the context of the Special Theory of Relativity, rest mass and relativistic mass are similarly analyzed as consequences of our presuppositions regarding physical systems. (shrink)

This article discusses connections between grounded action, leverage points, and paradigm transformation and transcendence. Part one provides background on Meadows' (1999) approach to leverage points as well as the concept of paradigms. Part two argues that grounded action is inherently suited for leverage points analysis and paradigm-based interventions. Part three offers an example of individual paradigm transformation in the educational context vis-à-vis Olson's (2006) grounded theory of driven succeeding. The article concludes with considerations of how the application (...) of grounded action in one classroom might leverage system-wide paradigm transformation. (shrink)

Measurement in soft systems generally cannot exploit physical sensors as data acquisition devices. The emphasis in this case is instead on how to choose the appropriate indicators and to combine their values so to obtain an overall result, interpreted as the value of a property, i.e., the measurand, for the system under analysis. This paper aims at discussing the epistemological conditions of the claim that such a process is a measurement, and performance evaluation is the case introduced to support the (...) analysis, performed in systematic comparison with the paradigm of measurement of physical quantities. Some background questions arising here are: – Are the chosen indicators appropriate performance indicators? – Do such indicators convey complete and non-redundant information on performance? – Does the chosen combination rule generate results suitably interpretable as performance values? And enlarging the focus: – Does the obtained value specifically convey information on the system under analysis, instead of some different entity (typically including the subject who is evaluating)? Operatively: would different subjects evaluate the same system in the same way? i.e., is the obtained information objective? – Does the obtained value convey information that is interpretable in the same way by different subjects? Operatively: would different subjects who have agreed on a decision procedure make the same decision from the same performance information? i.e., is the obtained information intersubjective? Any well founded positive answers to these questions significantly support a structural interpretation of measurement encompassing both physical and soft measurement. (shrink)

La présente étude se propose de repérer les traits principaux de la théorie des systèmes autopoïétiques qui a, depuis le début des années 80, fortement marqué les discours des sciences sociales en Allemagne. Notre analyse se réfère aux concepts-clé de ce nouveau paradigme, élaboré par Niklas Luhmann, et montre leur fonctionnement. La genèse du sens telle quelle s'opère dans la société moderne se trouve au centre de l'intérèt. Avec ses trois dimensions constituantes , le sens peut être mieux observé dans (...) l'ensemble des systèmes, qui est englobé par un environnement de plus en plus complexe. Finalement nous observerons, à titre d'essai, le système littéraire pour y relever les possibilités et les limites de cette nouvelle approche.In the past decade, the mainstream-discourses in German Social Sciences have been strongly influenced by the theoretical design proposed by Niklas Luhman, which is generally called Systems Theory.

Is a better observation garanteed by the unfolding three dimensions of sense ? An exemple like the literary system will show the possibilities and limits of this new paradigm in Social Sciences.

From understanding ageing to the creation of artificial membrane‐bounded ‘organisms’, systems biology and synthetic biology are seen as the latest revolutions in the life sciences. They certainly represent a major change of gear, but paradigm shifts? This is open to debate, to say the least. For scientists they open up exciting ways of studying living systems, of formulating the ‘laws of life’, and the relationship between the origin of life, evolution and artificial biological systems. However, the ethical and societal (...) considerations are probably indistinguishable from those of human genetics and genetically modified organisms. There are some tangible developments just around the corner for society, and as ever, our ability to understand the consequences of, and manage, our own progress lags far behind our technological abilities. Furthermore our educational systems are doing a bad job of preparing the next generation of scientists and non‐scientists. (shrink)

Systems biology is today such a widespread discipline that it becomes difficult to propose a clear definition of what it really is. For some, it remains restricted to the genomic field. For many, it designates the integrated approach or the corpus of computational methods employed to handle the vast amount of biological or medical data and investigate the complexity of the living. Although defining systems biology might be difficult, on the other hand its purpose is clear: systems biology, with its (...) emerging subfields systems medicine and systems pharmacology, clearly aims at making sense of complex observations/experimental and clinical datasets to improve our understanding of diseases and their treatments without putting aside the context in which they appear and develop. In this short review, we aim to specifically focus on these new subfields with the new theoretical tools and approaches that were developed in the context of cancer. Systems pharmacology and medicine now give hope for major improvements in cancer therapy, making personalized medicine closer to reality. As we will see, the current challenge is to be able to improve the clinical practice according to the paradigm shift of systems sciences. (shrink)

The paper presents an approach for developing multi-agent reinforcement learning systems that are made up of a coalition of modular agents. We focus on learning to segment sequences (sequential decision tasks) to create modular structures, through a bidding process that is based on reinforcements received during task execution. The approach segments sequences (and divides them up among agents) to facilitate the learning of the overall task. Notably, our approach does not rely on a priori knowledge or a priori structures. Initial (...) experiments demonstrated the basic promise of the approach. This work shows how bidding and reinforcement learning can be usefully combined, thus pointing to a new research direction.

EDUCERE is a government funded research and development project. EDUCERE objectives are to investigate, develop, and evaluate innovative solutions for society to detect changes in psychomotor development through the natural interaction of children with toys and everyday objects, and perform stimulation and early attention activities in real environments such as home and school. In the EDUCERE project, an ethical impact assessment is carried out linked to a minors’ data protection rights. Using a specific methodology, the project has achieved some promising (...) results. These include use of a prototype of smart toys to detect development difficulties in children. In addition, privacy protection measures which take into account the security concerns of health data, have been proposed and applied. This latter security framework could be useful in other Internet of Things related projects. It consists of legal and technical measures. Special attention has been placed in the transformation of bulk data such as acceleration and jitter of toys into health data when patterns of atypical development are found. The article describes the different security profiles in which users are classified. (shrink)

Does systems theory need rethinking? Most social scientists would probably say no. It had its run, was debated critically, and found wanting. If at all, it should be treated historically. Why then might systems theory need rethinking, as the title of this symposium claims? The reason is that, unlike in the natural and biosocial sciences, any conception of system in the social sciences has remained suspect in the wake of problematic Parsonian and cybernetic systems theories. The premise of this special (...) issue is that abandoning conceptions of systems has imposed a high price on the social sciences: a lack of ontologies and methodologies that are both philosophically profound and scientifically defensible. It has left social scientists who choose to ignore ontology in their theoretical and empirical work defenseless against enterprising settlers from a variety of humanities and social science disciplines who attack mainstream work with—often simplistic and naïve, but nevertheless fundamental—philosophical arguments, whether anti-scientific postmodernists or pseudo-scientific rational choice theorists. The goal of this special issue is to showcase new and original work that contributes to a rethinking of systems theory by taking the conception of systems seriously. This introduction offers a programmatic statement of a systemic ontology and methodology as well as a brief general outline and examples of what a systems-based approach in the social sciences entails. Key Words: systems theory • systemism • systemic approach • complexity theory • self-organization • emergentism • paradigms • social mechanisms • Mario Bunge. (shrink)

School gardens and garden-based learning continue to gain great popularity in the United States, and their pedagogical potential, and ability to impact students’ fruit and vegetable consumption and activity levels have been well-documented. Less examined is their potential to be agents of food system reskilling and transformation. Though producer and consumer are inextricably linked in the food system, and deskilling of one directly influences the other, theorists often focus on production-centered and consumption-centered deskilling separately. However, in a school garden, the (...) production/consumption disconnect is erased, by virtue of the design of the site itself and how it is utilized by the actors within it. School gardens provide the critical component of education in alternative food networks, and contribute to the producer/consumer reskilling that is a necessary part of food system transformation. We conducted a case study of an established school garden program during its transition from autonomous non-profit to official, district-funded program of a rural school district in the Midwest. By participating in the full “seed to plate” life cycle of a garden crop, students in the garden were actively involved in the reconnection of producer and consumer, while educators were fostering in students an appreciation for fresh, healthy foods and actively challenging the “McDonaldization” of both students’ diets and education. Based upon these findings, we argue that school gardens in rural areas could leverage the dominant role of rural America in developing and shifting food system paradigms. (shrink)

Comprising almost a third of greenhouse gas emissions and having an equally prominent role in pollution of soils, fresh water, coastal ecosystems, and food chains in general, agriculture is, alongside industry and electricity/heat production, one of the three biggest anthropogenic causes of breaching the planetary boundaries. Most of the problems in agriculture, like soil degradation and diminishing biodiversity, are caused by unfit uses of existing technologies and approaches mimicking the agriculturally-relevant functioning natural ecosystems seem necessary for appropriate organization of our (...) toxic and entropic agro-technologies. Our thesis is that eco-curative and sustainable uses of agro-technology require a paradigm shift from the chemical model of agro-systems to the ecological system-design model of agriculture. Particularly, following the new biomimetic paradigm of ecological innovation, we question in what sense can we mimic natural solutions in agriculture. We discern among Integrated agriculture and Permaculture, analyze their biomimetic status from the perspective of the philosophy of biomimicry, and argue that the former nature-mentored approach is a more appropriate solution for sustainable broadscale agriculture necessary for the growing world. However, it is not clear how this agricultural bio-integration will interact with the predicted automatization of work, urban demographic momentum, and the Earth system instability, and can the Permaculture alternative emerge as a social safety-net for the anticipated technologically-redundant or economically or environmentally endangered workers. We argue both for the importance to understand Permaculture as a social safety-net and as experimental testing ground for cutting edge biomimetic technologies. (shrink)

Many traditional agroecosystems found in Latin America constitute major in situ repositories of crop genetic diversity. This native germplasm is crucial to developing countries and industrialized nations alike. Native varieties expand and renew the crop genetic resources of developed countries while also performing well under the ecological and economic conditions of the traditional farms where they are grown. With agricultural modernization and environmental degradation, crop genetic diversity is decreasing in peasant agricultural systems. Research is urgently needed to document rates and (...) causes of genetic erosion in these systems and the role that peasants play in maintenance of crop genetic diversity. It is proposed that multi-disciplinary teams that work under the paradigms of ethnoecology and agroecology be assembled to integrate farmers’ knowledge with Western scientific approaches to design meaningful in situ crop genetic conservation strategies.

The innovation systems approach has swiftly spread out worldwide in the last three decades and stood as an important framework for policy-making in the fields of science, technology, and innovation. At the same time, there have been serious and untreated concerns in the literature about the theoretical soundness of this approach. Our discussion in this paper is based on the belief that a detailed analysis on epistemological foundations of the approach could shed a judgmental light on the aforementioned concerns. To (...) provide that analysis, we reconstructed and studied the nature and evolution of innovation systems approach as a case of conceptual revolution against the more established traditions in economics of innovation. Our analyses show that the rise of the systemic view of innovation include radical changes in conceptual structures pertaining to orthodox view of innovation. These developments also go so far as to include significant shifts in epistemological foundations of the old paradigm. These later shifts provide us with an epistemological base from which we can shelter the innovation systems approach from the hard criticisms rooted in a quasi-positivist point of view. That epistemological base also shows the path for the future development of the approach towards more robustness and precision. (shrink)

Most writers now recognize that mental health policy and the mental health system are extremely resistant to real changes that reflect genuine biopsychosocial paradigms of mental disorder. Writers bemoaning the intransigence of the mental health system tend to focus on a small analytical level, only to find themselves mired in the rationalities of the existing system. Problems are acknowledged to be system-wide, yet few writers have used a method of analysis appropriate for systemic problems. Drawing upon the General System (...) Theory (GST) analytical perspective, this article advances a systematic approach to understand the mental health system and to facilitate the development of reform strategies that recognize the system's complexity and changing nature. The article first discusses the failure of major reform efforts in the mental health system and the limitations of mainstream analysis of mental health politics and policies with respect to the objectives of analysis and reform. This article describes how systems thinking has thus far influenced the study of the mental health policy and politics system, and argues that a systemic perspective is profitable for reconceiving the mental health system, enabling a fresh basis for the development of reform strategies. The mental health system should be seen as a social system influenced by larger political and economic dimensions, not just as a 'delivery system' scientifically constructed by neutral experts. Furthermore, the policy planning process should be viewed as part and parcel of a mental health system modeled as complex and dynamic. The systemic perspective outlined here should help both to clarify the value-based objectives that we hold for the system and, consequently, to plan for the strategic reforms that have so far eluded us.

Adopting a different method from the previous scholars, this article deduces the remaining 23 valid syllogisms just taking the syllogism AEE-4 as the basic axiom. The basic idea of this study is as follows: firstly, make full use of the trichotomy structure of categorical propositions to formalize categorical syllogisms. Then, taking advantage of the deductive rules in classical propositional logic and the basic facts in the generalized quantifier theory, we deduce the remaining 23 valid categorical syllogisms by taking just one (...) syllogism (that is, AEE-4) as the basic axiom. This article not only reveals the reducible relations between the syllogism AEE-4 and the other 23 valid syllogisms, but also establishes a concise formal axiomatic system for categorical syllogistic logic. We hope that the results and methods will provide a good mathematical paradigm for studying other kinds of syllogistic logics, and that the project will appeal to specialists in logic, linguistic semantics, computational semantics, cognitive science and artificial intelligence.

The two contrasting theoretical approaches to visual perception, the constructivist and the ecological, are briefly presented and illustrated through their analyses of space and size perception. Earlier calls for their reconciliation and unification are reviewed. Neurophysiological, neuropsychological, and psychophysical evidence for the existence of two quite distinct visual systems, the ventral and the dorsal, is presented. These two perceptual systems differ in their functions; the ventral system's central function is that of identification, while the dorsal system is mainly engaged in (...) the visual control of motor behavior. The strong parallels between the ecological approach and the functioning of the dorsal system, and between the constructivist approach and the functioning of the ventral system are noted. It is also shown that the experimental paradigms used by the proponents of these two approaches match the functions of the respective visual systems. A dual-process approach to visual perception emerges from this analysis, with the ecological-dorsal process transpiring mainly without conscious awareness, while the constructivist-ventral process is normally conscious. Some implications of this dual-process approach to visual-perceptual phenomena are presented, with emphasis on space perception. Key Words: constructivist; dual-process approach; ecological; size perception; space perception; two visual systems; visual perception theories. (shrink)

Expert systems have had little impact as computing artifacts. In this paper we argue that the reason for this stems from the underlying assumption of most builders of expert systems that an expert system needs to acquire information and to control the interaction between the human user and itself. We show that this assumption has serious linguistic and usability flaws which diminish the likelihood of producing socially acceptable expert systems. We propose a reversal of this paradigm, for the design (...) of expert systems, by assuming that it is the human user who needs to acquire information and to control the interaction between themselves and the system.

Illative combinatory logic consists of the theory of combinators or lambda calculus extended by extra constants (and corresponding axioms and rules) intended to capture inference. The paper considers systems of illative combinatory logic that are sound for first-order propositional and predicate calculus. The interpretation from ordinary logic into the illative systems can be done in two ways: following the propositions-as-types paradigm, in which derivations become combinators or, in a more direct way, in which derivations are not translated. Both translations (...) are closely related in a canonical way. The two direct translations turn out to be complete. The paper fulfills the program of Church [1932], [1933] and Curry [1930] to base logic on a consistent system of λ-terms or combinators. Hitherto this program had failed because systems of ICL were either too weak (to provide a sound interpretation) or too strong (sometimes even inconsistent). (shrink)

Systems and synthetic biology promise to revolutionize our understanding of biology, blur the boundaries between the living and the engineered in a vital new bioengineering, and transform our daily relationship to the living world.

Cognitive science's basic premises are under attack. In particular, its focus on internal cognitive processes is a target. Intelligence is increasingly interpreted, not as a matter of reclusive thought, but as successful agent-environment interaction. The critics claim that a major reorientation of the field is necessary. However, this will only occur when there is a distinct alternative conceptual framework to replace the old one. Whether or not a serious alternative is provided is not clear. Among the critics there is some (...) consensus, however, that this role could be fulfilled by the concept of a 'behavioral system'. This integrates agent and environment into one encompassing general system. We will discuss two contexts in which the behavioral systems idea is being developed. Autonomous Agents Research is the enterprise of building behavior-based robots. Dynamical Systems Theory provides a mathematical framework well suited for describing the interactions between complex systems. We will conclude that both enterprises provide important contributions to the behavioral systems idea. But neither turns it into a full conceptual alternative which will initiate a major paradigm switch in cognitive science. The concept will need a lot of fleshing out before it can assume that role.

The paper questions the expert system paradigm, both in terms of its range of application, and as a significant contribution to the understanding of artificial intelligence. The viewpoint is that of the systems designer who must judge the applicability of these methods in imminent and future systems. The expert system paradigm, (ESP for short), is criticised not because it is ubiquitously wrong, but because its range of application appears to be very limited, and much promise is made of (...) its application in areas where its success is likely to be little more than a matter of luck. The paper considers the success in both academic and commercial settings. It is suggested that the contribution of the ESP to the wider ambitions of AI is modest, and to the practical user is still a considerable and largely unquantifiable risk. (shrink)

In the last two decades Information and Computer Technology has come to play an increasingly important role in medicine and health care. Many medical practitioners and scholars wonder: will e-health cause a paradigm shift in health care? To answer this question we provide a philosophical analysis of the concept of the 'paradigm shift' through the work of Michel Foucault, Thomas Kuhn and Larry Laudan. Their work offers key insights to a comprehensive understanding of major evolutions in medicine. Nowadays (...) the long-standing curative paradigm in medicine is facing important challenges due to an aging population, a significant increase in chronic diseases and the development of more expensive diagnostic tools and therapies. This promotes the evolution towards a new paradigm in medicine with an emphasis on preventive, predictive and personalized care. E-health constitutes an essential part of this new paradigm that seeks to solve the challenges presented by an aging population, skyrocketing costs and so forth. On the other hand the characteristics of e-health will be strongly determined by this new paradigm. 'Will e-health cause a paradigm shift in medicine?' might not be the right question to pose. Rather, we should ask how the underlying paradigm shift, from discovery and cure to prevention and prediction, acts as a facilitator to embrace ICT in health care. This analysis is of crucial importance in understanding the impact of digital health care applications and provides a necessary framework for the emerging, dynamic system of e-health. (shrink)
