The rôle of mathematical models in growth studies is discussed and a distinction made between the structural and descriptive aspects of a mathematical formulation. A simple scheme is set up to represent in broad outline the simultaneous growth and interaction of larval and adult systems inMyrmica rubra and is matched against observed results.

This article examines a fundamental theoretical aspect of the discourse on ‘intersectionality’ in feminist and anti-racist social theory, namely, the question whether intersecting social divisions including those of sex, gender, race, class and sexuality are interacting but independent entities with autonomous ontological bases or whether they are different dimensions of the same social system that lack separate social ontologies and constitute each other. Based on a historical reconstruction of its genesis, the article frames this as a dispute between system-theoretical and (...) dialectical, ‘Critical Theory’-related approaches and argues that the latter better capture the dynamics of contemporary society, including the perspective of its transcendence.

The observed complexity of nature is often attributed to an intrinsic propensity of matter to self-organize under certain (e.g., dissipative) conditions. In order better to understand and test this vague thesis, we define complexity as “logical depth,” a notion based on algorithmic information and computational time complexity. Informally, logical depth is the number of steps in the deductive or causal path connecting a thing with its plausible origin. We then assess the effects of dissipation, noise, and spatial and other symmetries (...) of the initial conditions and equations of motion on the asymptotic complexity-generating abilities of statistical-mechanical model systems. We concentrate on discrete, spatially-homogeneous, locally-interacting systems such as kinetic Ising models and cellular automata. (shrink)

This paper reflects on discussions within the Social Intelligence for Tele-healthcare (SIFT) project. The SIFT project aims to establish a model of social intelligence, to support the user-centred design of social intelligence in interactive systems. The conceptual background of social intelligence for the SIFT project is presented. Five challenges identified for the design of socially aware interactions are described, and their implications are discussed.

Cybernetic theory and interactivity have much in common, including human interrelationships between modern technology and how they define and reveal the whole interactive process. Most of the key notions in both can be described as the system in conversation about the system, talking to each other through the information passed back and forth between the particular relationship in audiences and artworks. These similar languages are feedback, control, conversation and system thinking in the field of cybernetic theory and interactive (...) artworks. As can be seen, some concepts of the cybernetic are applicable to interactivity. So, how can cybernetic thinking be applied to interactive artworks? The purpose of this article is to explore the interplay of cybernetics theory and interactivity and the connection between cybernetic/system thinking and technological/interactive artworks by illustrating the similarity of characteristics and comparing the conversation of two network systems. The goal is to deconstruct and reshape their relationships by thinking of interactive artworks in the way of cybernetic thinking. (shrink)

Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed (...) and implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants’ horizontal, pair‐wise interactions (...) led “bottom up” to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community‐evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.

In this article we present a parameterized model for generating multimodal behavior based on cultural heuristics. To this end, a multimodal corpus analysis of human interactions in two cultures serves as the empirical basis for the modeling endeavor. Integrating the results from this empirical study with a well-established theory of cultural dimensions, it becomes feasible to generate culture-specific multimodal behavior in embodied agents by giving evidence for the cultural background of the agent. Two sample applications are presented that make use (...) of the model and are designed to be applied in the area of coaching intercultural communication. (shrink)

The sophisticated function of the central nervous system (CNS) is largely supported by proper interactions between neural cells and blood vessels. Accumulating evidence has demonstrated that neurons and glial cells support the formation of blood vessels, which in turn, act as migratory scaffolds for these cell types. Neural progenitors are also involved in the regulation of blood vessel formation. This mutual interaction between neural cells and blood vessels is elegantly controlled by several chemokines, growth factors, extracellular matrix, and adhesion molecules (...) such as integrins. Recent research has revealed that newly migrating cell types along blood vessels repel other preexisting migrating cell types, causing them to detach from the blood vessels. In this review, we discuss vascular formation and cell migration, particularly during development. Moreover, we discuss how the crosstalk between blood vessels and neurons and glial cells could be related to neurodevelopmental disorders. (shrink)

Large-screen human-computer interaction technology is reflected in all aspects of daily life. The dynamic gesture tracking algorithm commonly used in recent large-screen interactive technologies demonstrates compelling results but suffers from accuracy and real-time problems. This paper systematically addresses these issues by a switching federated filter method that combines particle filtering and Mean Shifting algorithms based on a 3D sensor. Compared with several algorithms, the results show that the one-hand and two-hand large-screen gesture tracking based on the switched federated filtering (...) algorithm work well, and there is no tracking failure and loss of target. Therefore, the switching federated tracking positioning algorithm can be well applied to the design of human-computer interaction system and provide new ideas for future human-computer interaction.

Computers are increasingly interactive. They are no more transformational systems producing a final output after a finite execution. Instead, they continuously react in time to external events that modify the course of computing execution. While philosophers have been interested in conceptualizing computers for a long time, they seem to have paid little attention to the specificities of interactive computing. We propose to tackle this issue by surveying the literature in theoretical computer science, where one can find explicit (...) proposals for a model of interactive computing. In that field, the formal modelling of interactive computing systems has been brought down to whether the new interaction models are reducible to Turing Machines. There are three areas where interaction models are framed. The comparison between TMs and interactive system models is at stake in all of them. These areas are namely some works on concurrency by Milner, on Reactive Turing Machines, and on interaction as a new computing paradigm. For each of the three identified models, we present its motivation, sum up its account for interaction and its legacy, and point out issues regarding the understanding of computers. The survey shows difficulties for epistemologists. The reason is that these analyses focus on the formal equivalence between interactive models of computation and classic ones. Such a project is different from addressing how a computing machine can be interactive: in other words, which mechanisms allow it. (shrink)

In “Coordination in interpersonal systems,” Emily Butler urges psychologists to move beyond a focus on the individual to better understand dynamic interpersonal systems. She argues that an improved understanding of coordination, in particular, will allow them to not only better understand human behaviour but also solve many social problems, especially polarisation. I agree with both this empirical shift and Butler's normative interest. This said, Butler's framework would benefit from more attention to social identity – which tends to structure (...) polarisation – and emotion – which fuels it. Butler's framework would also be enriched by incorporating knowledge accumulated by political scientists on the import of institutions, the history of party coalitions, and the pursuit of power by social actors. With respect to a reform agenda, a possible place to start is lessening partisan polarisation and thereby strengthening democratic governance, which, at its best, represents an inclusive and synergistic system of human interaction.

This paper will discuss interactive on-line artworks modelled on cellular automata that employ various types of agents, both algorithmic and human, to assist in the evolution of their databases. These works constitute what will here be referred to as “Collaborative Systems” systems that evolve through the practice of inter-authorship.

Large tracts of European rural land, mostly in the less favored areas (LFA), are devoted to low-inputs and large scale grazing systems (LSGS) with potential environmental and social functions. Although these LSGS may provide harbor for a good part of European nature values, their continuity is facing contrasting threats of intensification and abandonment. These areas, however, may be characterized by particular grazing structures and social dynamics of change that should be unveiled prior to attempts to devise rural development strategies (...) or to adapt policy frameworks in general. To wit, stakeholder interactions and legal and institutional processes are described and analyzed for the cereal-sheep system of Castile-La Mancha (CLM) in the central Iberian plain. Farmers and pastoralists still share the use of the land, but their roles and interests have changed over time, and particularly in the last 50 years. Arable farming, mainly cereal cropping, has followed an intensification path, partially tempered by the environmental constraints of the Castilian plain. Extensive pastoralism is still a secondary option of land use; in the main, sheep farmers depend on, and look to, the management practices of arable farmers. A mixed cereal and sheep operation may deliver environmental and economic benefits, but successful implementation of this strategy is only possible when the system serves the needs of both types of stakeholders. Paradoxically, the main drivers of change in the countryside overall are arrayed against this sensible and traditional agricultural system. We argue that the recent legal and institutional frameworks do not favor social cohesion and that policy-support schemes of the European Union (EU) have been, and continue to be, devised without taking into account the particular structures and social dynamic of the farming system.

Driven by population pressures on natural resources, peri-urban pastoralists in the Far North Province of Cameroon have recently intensified livestock production in their traditional pastoral system by feeding their cattle cottonseed cakes and other agricultural byproducts to cope with the disappearance of rangelands typically available through the dry season. Although the crop–livestock interactions in this altered intensive pastoral system seem similar to alterations recently named in mixed-farming systems in West Africa, they are distinctly different and would require a different (...) type of agricultural development support. I use Bourdieu’s theoretical constructs of “habitus” and “capital” to explain those differences. (shrink)

The United States National Preparedness System has evolved significantly in the recent past. These changes have affected the system structures and goals for disaster response. At the same time, actors such as private businesses have become increasingly involved in disaster efforts. In this paper, we begin to fill the gap in the cross-sector literature regarding interactions that have systemic impacts by investigating how the simultaneous processes of systemic change and intensifying cross-sector interaction worked and interacted in the context of the (...) preparedness system. We examine these inter-linkages through a qualitative study in the setting of Hurricane Sandy. Drawing from systems theory, we develop a grounded model that provides an explanation for the system change and highlights how cross-sector interaction relates to the changes observed in the system.

The Logocratic Method, and the Logocratic theory that underwrites it, provide a philosophical explanation of three purposes or goals that arguers have for their arguments: to make arguments that are internally strong, or that are dialectically strong, or that are rhetorically strong. This article presents the basic terms and methods of Logocratic analysis and then uses a case study to illustrate the Logocratic explanation of arguments. Highlights of this explanation are: the use of a virtue framework to explicate the three (...) strengths and weaknesses of arguments that are of greatest interest to arguers in many contexts, the Logocratic explication of the structure of abduction generally and of legal abduction specifically, the concept of a system of arguments, and the concept of the dynamic interactive virtue of arguments—a property of systems of arguments in which the system of arguments as a whole is as virtuous as are the component arguments that comprise the system. This is especially important since, according to Logocratic theory, some arguments, such as abduction and analogical argument, are themselves comprised of different logical forms. (shrink)

In October 2011, the “2nd European Network for Cognitive Systems, Robotics and Interaction”, EUCogII, held its meeting in Groningen on “Autonomous activity in real-world environments”, organized by Tjeerd Andringa and myself. This is a brief personal report on why we thought autonomy in real-world environments is central for cognitive systems research and what I think I learned about it. --- The theses that crystallized are that a) autonomy is a relative property and a matter of degree, b) increasing (...) autonomy of an artificial system from its makers and users is a necessary feature of increasingly intelligent systems that can deal with the real-world and c) more such autonomy means less control but at the same time improved interaction with the system.

Although emotion is closely associated with motivation, and interacts with perception, cognition, and action, many conceptualizations still treat emotion as separate from these domains. Here, a comparative/evolutionary anatomy framework is presented to motivate the idea that long-range, distributed circuits involving the midbrain, thalamus, and forebrain are central to emotional processing. It is proposed that emotion can be understood in terms of large-scale network interactions spanning the neuroaxis that form “functionally integrated systems.” At the broadest level, the argument is made (...) that we need to move beyond a Newtonian view of causation to one involving complex systems where bidirectional influences and nonlinearities abound. Therefore, understanding interactions between subsystems and signal integration becomes central to unraveling the organization of the emotional brain. (shrink)

We present a theoretical discussion of the sociological contribution concerning decisions in organizations. Two theories stand. The first, based on the decision process from a critical theory of the traditional linear multi rational by Lucien Sfez, argues that the decision is a process of interactions and treats it as an institutional process based on the freedom of the subject. The second theory based on self-referential systems by Niklas Luhmann, interprets organizations as systems-making, and understands the concept of decision (...) as purely epistemological specificity, abstracted from the decision of all the elements and organizational variables associated with it. Se expone un debate teórico sobre la aportación sociológica referente a las decisiones en las organizaciones. Sobresalen dos teorías de las decisiones. La primera, basada en el proceso de decisión a partir una teoría crítica de la multirracionalidad lineal elaborado por Lucien Sfez, al plantear que con la decisión se trata de un proceso de interacciones, al ser considerada como un proceso institucional fundamentado en la libertad del sujeto. La segunda fundamentada en la teoría de sistemas autorreferenciales, interpreta las organizaciones como sistemas de decisiones y entiende el concepto de decisión en su especificidad puramente epistemológica, al abstraer de la decisión de todos los elementos y variables organizacionales relacionados con ella (Niklas Luhmann).

The following essay begins by outlining the pragmatist link between truth claims and democratic deliberations. To this end, special attention will be paid to Jeffrey Stout’s pragmatist enfranchisement of religious citizens. Stout defends a deliberative notion of democracy that fulfills stringent criteria of inclusion and security against domination. While mitigating secular exclusivity, Stout nonetheless acknowledges the new visibility of religion in populist attempts to dominate political life through mass rule and charismatic authorities. In response, I evaluate recent innovations in deliberative (...) democratic systems theory (DDST). By adding a pragmatist inflection to DDST, I aim to apprehend the complex religious interactions between partisan interest groups as well as the trust-building capacities of minipublics. (shrink)

The subject of the research is a modern graphic and communicative design, in the context of changing existing and forming new roles of communicators, transforming the communication model, forming a semiotic communication format. The object of the research is modern graphic and communicative design, as well as their traditional, digital and generative subdirections. Design beginning to have digital, semiotic-interactive and artificially intelligent characteristics. The author examines in detail such aspects of the topic as: dialogical, semiotic-interactive qualities of design (...) solutions; digital, semiotic-interactive design-software expressive means; features of semiotic-deconstructivity (analyticity) and semiotic-synthetics (constructiveness) of design solutions in the context of design activity; the influence of technical and technological features of tools and design-environments (design systems) for the formation of automated and artificially intelligent qualities of design solutions. The study of the conceptual model of a semiotic-interactive design is carried out in the context of a semiotic-interactive methodology (a set of principles and strategies of design activity). The main conclusions of the study are the description of the conceptual model of a semiotic-interactive design solution, in the context of a semiotic-interactive methodology implemented in the conceptual-generative subdirection of modern graphic and communicative design. The author's main contribution to the research of the topic is to identify the main components of the conceptual model of a semiotic-interactive design solution and demonstrate their relationship with each other in the form of a holistic model. The novelty of the research lies in the description of the characteristics of the components, the conceptual model of a semiotic-interactive design solution: a dialogical semiotic-interactive format for creating invariant concepts and design solutions; versioning of design solutions based on the semiotic synthesis of design programs; semiotic deconstruction of design solutions at the macro and micro levels; semiotic synthesis of design and artistic design programs; application of design programs as decision tools; use of hyperconnected capabilities of the design environment: the history of actions, integrity and continuous change and development.
