It is usually the case that scientists examine either ecological systems or social systems, yet the need for an interdisciplinary approach to the problems of environmental management and sustainable development is becoming increasingly obvious. Developed under the auspices of the Beijer Institute in Stockholm, this new book analyses social and ecological linkages in selected ecosystems using an international and interdisciplinary case study approach. The chapters provide detailed information on a variety of management practices for dealing with (...) environmental change. Taken as a whole, the book will contribute to the greater understanding of essential social responses to changes in ecosystems, including the generation, accumulation and transmission of ecological knowledge, structure and dynamics of institutions, and the cultural values underlying these responses. A set of new (or rediscovered) principles for sustainable ecosystem management is also presented. Linking Social and Ecological Systems will be of value to natural and social scientists interested in sustainability. (shrink)

In this new and greatly expanded edition of his 1991 classic Political Ecology, Dimitri Roussopoulos delves into the history of environmentalism to explain the failure of the State's management of the ecological crisis. He explores civil society's various past responses and the prospects for channeling environmentalist aspirations into political alternatives, emphasizing the ideas of social ecology and the central role of democratic neighborhoods and cities in developing alternatives. Ecologists, Roussopoulos argues, aim for more than simply protecting the environment- they (...) call for new communities, new lifestyles, and a new way of doing politics. (shrink)

Resilience thinking challenges us to reconsider the meaning of sustainability in a world that must constantly adapt in the face of gradual and at times catastrophic change. This volume further asks environmental education and resource management scholars to consider the relationship of environmental learning and behaviours to attributes of resilient social-ecological systems - attributes such as ecosystem services, innovative governance structures, biological and cultural diversity, and social capital. Similar to current approaches to environmental education and education for sustainable (...) development, resilience scholarship integrates social and ecological perspectives. The authors of _Resilience in social-ecological systems: the role of learning and education_ present a wealth of perspectives, integrating theory with reviews of empirical studies in natural resource management, and in youth, adult, and higher education. The authors explore the role of education and learning in helping social-ecological systems as they respond to change, through adaptation and transformation. This book also serves to integrate a growing literature on resilience and social learning in natural resources management, with research in environmental education and education for sustainable development. This book was originally published as a special issue of _Environmental Education Research_. (shrink)

To sustainably govern a Social-Ecological System (SES), both the academic literature and practitioners recommend involving a broad range of actors—public or private—from the territory in question. Nonetheless, the presence of actors in collaborative SES governance processes is not a given. Since this presence requires time and energy without direct personal reward, it depends on the actors’ likelihood to embrace a stewardship role, which in turn depends on their relationship with their biophysical and social contexts. This paper studies the role (...) played by actors’ places of residence in their stewardship behavior in collaborative SES governance. To this end, we analyze the attendance patterns of over 600 members of a French River Basin Committee over 26 years, to shed light on the biophysical determinants. We find that individuals’ biophysical experience plays a critical role in motivating ‘place stewardship’ behavior—especially for key groups of actors such as farmers. We discuss the challenges that place stewardship poses for SESs and outline measures for fostering broader SES stewardship. (shrink)

Growing ecological problems have raised the need for conceptual tools dedicated to studying semiotic processes in cultural-ecological systems. Departing from both ecosemiotics and cultural semiotics, the concept of an ecosemiosphere is proposed to denote the entire complex of semiosis in an ecosystem, including the involvement of human cultural semiosis. More specifically, the ecosemiosphere is a semiotic system comprising all species and their umwelts, alongside the diverse semiotic relations (including humans with their culture) that they have in the (...) given ecosystem, and also the material supporting structures that enable the ecosemiosphere to thrive. Drawing parallels with Juri Lotman’s semiosphere concept, the ecosemiosphere is characterized by its heterogeneity, asymmetry, and boundedness. But unlike Lotman’s concept, the ecosemiosphere is not characterized by an overall boundedness, that is, by the presence of external binary boundaries and the shared identity arising from this unity. The involvement of human culture in the ecosemiosphere manifests in interspecies dialogues and semiotic engagements. We need to scrutinize what affordances and semiotic resources culture could offer to nonhuman species and how culture could, by semiotic means, raise the integrity, stability, and resiliency of the ecosystem. The ecosemiosphere is a grounded semiosphere. (shrink)

This paper proposes an epistemological approach to analyse social-ecological systems from a process perspective in order to better tackle the co-constitution of the social and the ecological and the dynamism of these systems. It highlights the usefulness of rethinking our conceptual tools taking processes and relations as the main constituents of reality instead of fundamental substances or essences. We introduce the concept of experience as understood in radical empiricism to critically revise our available concepts through focusing (...) on the concept of difference, exploring apparent contradictions and engaging in assemblage thinking.

Well-intended natural resource policies that ignore the complexity of socio-ecological systems too often threaten local values and opportunities for sustainable development. Upland areas throughout Indonesia provide examples of complex socio-ecological systems experiencing rapid socio-economic and environmental transformations in response to interactions between development policies and local agendas. Broad natural resource policies influence socio-ecological systems in different ways. In some cases, there are converging national and local goals, while in others the goals of national policy (...) conflict with local aspirations. This study identifies how broadscale policies could respond to the unique characteristics of upland areas to optimise development outcomes and avoid unintended risks for people and the landscape. The theory of reflexive modernity is utilised to illustrate how two national policies, the Community Forestry initiative and the Irrigation Reservoir program, largely discount the complexity of local values in the uplands of Pagar Alam, Indonesia. We identify local farmer aspirations through an analysis of development narratives and relate how they are impacted upon by the two policies. Our findings indicate that dominant development goals and associated sustainability pathways diverge in a range of ways from local farmer values and aspirations. We suggest that policymakers take more consideration of four interacting elements, namely: local ecological traits; local values and institutions; the multiple development pathways; and exogenous market drivers that affect local development, to promote sustainability and increase the likelihood of achieving all desired policy outcomes.

This paper investigates the fundamental idea at stake in current bioeconomies such as Europe's Bio-Based Economy (BBE). We argue that basing an economy upon ecology is an ambivalent effort, causing confusion and inconsistencies, and that the dominant framing of the damaged biosphere as a market-failure in bioeconomies such as the BBE is problematic. To counter this dominant narrative, we present alternative conceptualisations of bio-economies and indicate which concepts are overlooked. We highlight the specific contradictions and discrepancies in the relation between (...) economy and ecology, and then work towards outlining a genuine and consistent conceptualisation of the BBE. The philosophical perspective of Emmanuel Levinas is employed to develop a more profound understanding of the tensions at stake; Levinas' work is compared with that of Nicholas Georgescu-Roegen's work on bioeconomics, and found to be of complementary value. Our hypothesis is that, rather than the impossible, absolute amalgamation of economy and ecology striven for today, a principal heterogeneity between humankind and nature must be acknowledged if a bioeconomy that truly operates within the carrying capacity of planet Earth is to be achieved.

Understanding causation in social-ecological systems (SES) is indispensable for promoting sustainable outcomes. However, the study of such causal relations is challenging because they are often complex and intertwined, and their analysis involves diverse disciplines. Although there is agreement that no single research approach (RA) can comprehensively explain SES phenomena, there is a lack of ability to deal with this diversity. Underlying this diversity and the challenge of dealing with it are different causal reasonings that are rarely explicit. Awareness (...) of hidden assumptions is essential for understanding how the causal reasoning of an RA is constituted, and for promoting the integration, translation, or juxtaposition of different RAs. We identify the following elements as particularly relevant for understanding causal reasoning: methods, frameworks and theories, accounts of causation, analytical focus, and causal notions. We begin with the idea that one of these elements typically figures as an entry point to an RA. This entry point is particularly important because it generates a path dependence that orients causal reasoning. In a subsequent step, when an approach is applied, causal reasoning concretizes as a result of a particular constellation of the remaining elements. We come to these insights by studying the application of four different RAs to the same social-ecological case (the collapse of Baltic cod stocks in the 1980s). On the basis of our findings we developed a guide for the analysis of causal reasoning by raising awareness of the assumptions, key elements, and the relations between these key elements for a given RA. The guide can be used to elicit the causal reasoning of RAs, facilitate interdisciplinary collaboration, and support disclosure of ethical/political dimensions that underlie management/governance interventions that are formulated on the basis of causal findings of research studies.

'Political reconciliation' refers to processes for establishing right relations between groups that are emerging from a history coloured by violent relations. However, dominant Western, euro-descendent philosophies of political reconciliation rarely focus on ecological forms of harm or consider practices of ecological violence as constitutive of the violent relations that reconciliation hopes to repair. This article argues that the exclusion of ecological dimensions of harm from dominant Western models of political reconciliation is one way of understanding Indigenous claims (...) of dissatisfaction with such reconciliation projects. This article analyses and contextualises these claims of dissatisfaction by focusing on how dominant Western, euro-descendent models of reconciliation in the North American context import settler-colonial commitments that obscure the primacy of ecological violence in settler-Indigenous land-based conflicts. Furthermore, this article posits that settler-colonial commitments in reconciliation models pose an obstacle to deeper forms of reconciliation, partly because these models uphold dominant euro-descendent cosmologies and conceptions of land over and above Indigenous ones. Finally, this article suggests that that the possibility of deep reconciliation exists, and requires engaging with Indigenous philosophies that place land and relations to land at the centre of right relations, thus working toward decolonising settler-colonial-infused forms of reconciliation.

Among the technologies addressed are geoengineering, human enhancement, sex selection, genetic modification, and synthetic biology.

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)

The literature on common pool resource (CPR) governance lists numerous factors that influence whether a given CPR system achieves ecological long-term sustainability. Up to now there is no comprehensive model to integrate these factors or to explain success within or across cases and sectors. Difficulties include the absence of large-N-studies (Poteete 2008), the incomparability of single case studies, and the interdependence of factors (Agrawal and Chhatre 2006). We propose (1) a synthesis of 24 success factors based on the current (...) SES framework and a literature review; (2) the application of neural networks on a database of CPR management case studies in an attempt to test the viability of this synthesis. This method allows us to obtain an implicit quantitative and rather precise model of the interdependencies in CPR systems. Given such a model, every success factor in each case can be manipulated separately, yielding different predictions for success. This could become be a fast and inexpensive way to analyze, predict and optimize performance for communities world-wide facing CPR challenges. Existing theoretical frameworks could be improved as well. (shrink)

The paper identifies the relation between ecology and environmentalism through the emergence of system theory.

A timely addition to Henry Giroux's Critical Interventions series, Ecology and Revolution is grounded in the Frankfurt School critical theory of Herbert Marcuse. Its task is to understand the economic architecture of wealth extraction that undergirds today's intensifying inequalities of class, race, and gender, within a revolutionary ecological frame. Relying on newly discovered texts from the Frankfurt Marcuse Archive, this book builds theory and practice for an alternate world system. Ecology and radical political economy, as critical forms of (...) class='Hi'>systems analysis, show that an alternative world system is essential - both possible and feasible - despite political forces against it. Our rights to a commonwealth economy, politics, and culture reside in our commonworks as we express ourselves as artisans of the common good. It is in this context, that Charles Reitz develops a GreenCommonWealth Counter-Offensive, a strategy for revolutionary ecological liberation with core features of racial equality, women's equality, liberation of labor, restoration of nature, leisure, abundance, and peace.

The influence of many factors on ecological success in common pool resource management is still unclear. This may be due to methodological issues. These include causal complexity, a lack of large-N-studies and nonlinear relationships between factors. We address all three issues with a new methodological approach, artificial neural networks, which is discussed in detail. It allows us to develop a model with comparably high predictive power. In addition, two success factors are analyzed: legal security and institutional fairness. Both factors (...) show a positive impact on success in irrigation and fisheries supporting the view that there are sector-independent success factors. (shrink)

This article examines the expansion of agrofuels in the Americas and the ecological impacts associated with the technologies used in the production of large-scale monocultures of corn and soybeans. In addition to deforestation and displacement of lands devoted to food crops due to expansion of agrofuels, the massive use of transgenic crops and agrochemical inputs, mainly fertilizers and herbicides used in the production of agrofuels, pose grave environmental problems.

Holobionts are symbiotic assemblages composed by a macrobe host plus its symbiotic microbiota. In recent years, the ontological status of holobionts has created a great amount of controversy among philosophers and biologists: are holobionts biological individuals or are they rather ecological communities of independent individuals that interact together? Chiu and Eberl have recently developed an eco-immunity account of the holobiont wherein holobionts are neither biological individuals nor ecological communities, but hybrids between a host and its microbiota. According to (...) their account, the microbiota is not a proper part of the holobiont. Yet, it should be regarded as a set of scaffolds that support the individuality of the host. In this paper, we approach Chiu and Eberl’s account from a metaphysical perspective and argue that, contrary to what the authors claim, the eco-immunity account entails that the microorganisms that compose the host’s microbiota are proper parts of the holobiont. Second, we argue that by claiming that holobionts are hybrids, and therefore, not biological individuals, the authors seem to be assuming a controversial position about the ontology of hybrids, which are conventionally characterized as a type of biological individual. In doing so, our paper aligns with the contemporary tendency to incorporate metaphysical resources to shed light on current biological debates and builds on that to provide additional support to the consideration of holobionts as biological individuals from an eco-immunity perspective.

Media ecology is not the theoretical stream of communication studies and it is not limited to Marshall McLuhan´s work and thinking; however, we focus on McLuhan’s approach to media ecology for this special issue on the philosophy of Marshall McLuhan. Media ecology is a complex and systemic metadiscipline whose object of study is the changes and effects that have occurred in society as a result of the evolution of technology and media throughout history.

Ontological and methodological constraints on a theory of cognition that would generalize across species are identified. Within these constraints, ecological arguments for animal-environment mutuality and reciprocity and the necessary specificity of structured energy distributions to environmental facts are developed as counterpoints to the classical doctrines of animal-environment dualism and intractable nonspecificity. Implications of and for a cognitive theory consistent with Gibson's programme of ecological psychology are identified and contrasted with contemporary cognitivism.

This paper reviews a selection of the literature that focuses on indigenous ecological knowledge systems and the accompanying cosmology and myth. Traditional ecological knowledge may not be obvious to the western trained scientist or the development worker since it may be disguised in the form of cosmology and ritual. The paper argues that the development process must be based on an understanding of traditional ecological knowledge if projects are to be sustainable both environmentally and sociologically.

Cognition means different things to different psychologists depending on the position held on the mind-matter problem. Ecological psychologists reject the implied mind-matter dualism as an ill-posed theoretic problem because the assumed mind-matter incommensurability precludes a solution to the degrees of freedom problem. This fundamental problem was posed by both Nicolai Bernstein and James J. Gibson independently. It replaces mind-matter dualism with animal-environment duality -- a better posed scientific problem because commensurability is assured. Furthermore, when properly posed this way, a (...) conservation law is suggested that encompasses a psychology of transactional systems, a biology of self-actional systems, and a physics of interactional systems. For such a solution, a theory of cognition for goal-directed behaviour is needed. A sketch is supplied for how such a theory might be pursued in the spirit of the new physics of evolving complex systems. (shrink)

Since the introduction and widespread adoption of chemical herbicides, “weed management” has become almost synonymous with “herbicide management.” Over-reliance on herbicides and herbicide-resistant crops has given rise to herbicide resistant weeds. Integrated weed management (IWM) identifies three strategies for weed management— biological-cultural, chemical-technological, mechanical-physical—and recommends combining all three to mitigate herbicide resistance. However, adoption of IWM has stalled, and research to understand the adoption of IWM practices has focused on single stakeholder groups, especially farmers. In contrast, decisions about weed management (...) often occur within a social ecosystem where multiple stakeholder groups co-create knowledge and practices. To more holistically investigate perceptions and decision-making related to herbicide resistant weed management, we conducted 23 in-depth interviews in combination with Q methodology with farmers and public-/private-sector agricultural professionals in the state of Georgia (U.S.). Our investigation focused on the management of an increasingly herbicide resistant weed, Palmer amaranth, which enabled broader conversations about agricultural systems, farmer livelihoods, and sustainability. Factor and thematic analyses allowed us to identify and characterize two distinct typologies: one primarily valued agronomic efficiency and relied upon chemical-technological management practices, while the other valued diversifying weed management strategies as the pathway to agronomic and economic success. Typologies diverged substantially in attitudes toward the three weed management strategies, the role of technology, and systems management generally. These two viewpoints have implications for how we understand underlying stakeholder motivations and choices around weed management strategies, both of which are crucial in promoting and supporting farmer use of diverse, ecologically-sound, weed management strategies.

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)

Many are calling for transformative food systems changes to promote population and planetary health. Yet there is a lack of research that considers whether current food policy frameworks and regulatory approaches are suited to tackle whole of food systems challenges. One such challenge is responding to the rise of ultra-processed foods (UPF) in human diets, and the related harms to population and planetary health. This paper presents a narrative review and synthesis of academic articles and international reports to (...) critically examine whether current food policy frameworks and regulatory approaches are sufficiently equipped to drive the transformative food systems changes needed to halt the rise of UPFs, reduce consumption and minimise harm. We draw on systems science approaches to conceptualise the UPF problem as an emergent property of complex adaptive food systems shaped by capitalist values and logics. Our findings reveal that current food policy frameworks often adjust or reform isolated aspects of food systems (e.g., prices, labels, food composition), but under-emphasise the deeper paradigms, goals and structures that underlie the rise of UPFs as a systems phenomenon, and its socio-ecological implications. We propose that a ‘leverage points’ framework illuminates where to intervene in food systems to generate multi-level changes, while the theory of ecological regulation highlights how to respond to complex multi-factorial problems, like the rise of UPFs, in diverse ways that respect planetary boundaries. More research is needed to better understand the transformative potential of ecological regulation to advance food systems transformation and attenuate whole of food systems challenges. (shrink)

In this article we provide a case history of the development of a communicative system in songbirds. In particular, we explore how brown-headed cowbirds, male and female, cooperate in the development and use of species-typical song. The goal is to show how social interactions between and within sexes create a platform for the production and perception of song. We consider six perspectives. First, we discuss the nature of the acoustic signal. Second, we look at the process of song learning. Third, (...) we describe a specific song mechanism, social shaping. Fourth, we look at the more general developmental process of neophenogenesis. Fifth, we consider the developmental ecology for social learning. Finally, we describe how social networks measures can be used to capture the nature of social interactions as the engines of song learning. Taken as a whole, we argue that culturally transmitted behaviors structure social interactions that predict the acquisition of species' typical behaviors necessary for successful reproduction.

This paper explores Wittgenstein’s early work as it relates to emerging philosophical problems in ecological modeling. Here I use his thought to structure a logical framework from which to discuss ecological simulation models in a way that captures how these dynamic representations describe a world from which we can draw logical inferences about real-world ecological processes. I argue that Wittgenstein’s Tractatus Logico-Philosophicus provides a way of reading problems that arise in using simulation as a way to make (...) inferences about the world. Conversely, ecological simulation provides an illustration of a Tractarian system, because the digital world it creates completely describes and is defined by the programing language. This reading is a novel, but productive, way that notes that the language used in modeling requires a hermeneutical approach to make inferences about modeling/real-world relationships. (shrink)

It has been reported in non-contingent schedules that the variety of patterns of behavior is affected by the temporal variation of water deliveries. While temporal variation is accomplished by delivering water at fixed or variable times, spatial variation is usually accomplished by varying the number of dispensers and distance among them. Such criteria do not consider the possible ecological relevance of the location of water dispensers. Nevertheless, it is plausible to suppose that the intersection of the programed contingencies, the (...) ecological differentiated space, and the relative location of relevant objects and events could set up an integrated system with the behavioral patterns of the organism. In the present study, we evaluated the eco-functional relevance of two locations of the dispensers upon behavioral dynamics in Wistar rats using fixed and variable time schedules in a modified open-field system. In Experiment 1, three subjects were exposed to a fixed time 30-s water delivery schedule. In the first condition, the water dispenser was located at the center of the experimental chamber. In the second condition, the water dispenser was located at the center of a wall of the experimental chamber. Each location was present for 20 sessions. In Experiment 2, conditions were the same, but a variable time schedule was used. Routes, distance to the dispenser, recurrence patterns, time spent in zones, entropy, and divergence were analyzed. Our findings suggest a robust differential relevance of the location of the dispensers that should be considered in studies evaluating behavioral dynamics. Results are discussed from an integrative, ecological-parametric framework. (shrink)

sBuilding models as a practical aspect of ecological theory has as a principal purpose the determination of relations in formal language. In this paper, the authors provide a formalization of ecological models based on impure systems theory. Impure systems contain objects and subjects: subjects are human beings. We can distinguish a person as an observer that by definition is the subject himself and part of the system. In this case he acquires the category of object. Objects (...) are significances, which are the consequence of perceptual beliefs on the part of the subject about material or energetic objects with certain characteristics. The impure system approach is as follows: objects are perceptual significances of material or energetic objects. The set of these objects will form an impure set of the first order. The existing relations between these relative objects will be of two classes: transactions of matter and/or energy and inferential relations. Transactions can have alethic modality: necessity, possibility, impossibility and contingency. In this work we define measures which let us choose the more suitable variables to relate both the model with the ecosystem and with different models. In this way we define different comparison indexes. (shrink)

The discrepancy between measures of preferred and actual participation in decision making was used as a measure of ecological dissonance for an organization and then used to assess its relationship to job satisfaction, job involvement, job alienation, and job formalization. Questionnaires were administered to 143 faculty and staff members of Mississippi State University. Correlational analyses indicated mild relationships between the measures of ecological dissonance and job satisfaction, job involvement, job alienation, and job formalization, thus providing support for (...) class='Hi'>ecological dissonance theory (see Miller, Topping, & Wells-Parker, 1989). It was concluded that ecological dissonance in participation in decision making was a predictor of workers’ job satisfaction, job involvement, job alienation, and job formalization. (shrink)

Building on the views of Kant and early nineteenth century life scientists, Hegel develops a view of systems that is a clear precursor to the developments in Ludwig von Bertalanffy’s general system theory, as well as the thinking of the ecologically minded system thinkers that built upon the foundation Bertalanffy laid. Hegel describes systems as organic wholes in which the parts respectively serve as means and ends. Further, in the Encyclopedia version of the logic Hegel notes that such (...) systems are comprised of three processes: gestalt, the process of assimilation, and regeneration. In Hegel’s texts, he describes both natural and social systems as organic wholes with such systematic processes. In this paper, these processes and systems are described and it is argued that Hegel quite consistently applies views developed in the logic when describing systems. The paper shows how this parallels later developments in systems theory and goes on to show some distinctions between Hegel’s view of systems and that of later ecologically minded system thinkers.

There are four main phenomenological components: directionality, intensity, connection energy and volume. A fundamental question in this approach to Impure Systems is the intensity or forces of a relation. Concepts as the system volume, and propose a system thermodynamic theory based in the Law of Zipf and the temperature of information are introduced. It hints at the possibility (...) of adapting the fractal theory by introducing the fractal dimension of the system. (shrink)

In biology, the ‘ecological orientation' rests on a commitment to examining systems, and the conceptual challenge of defining that system now employs techniques and concepts adapted from diverse disciplines (i.e., systems philosophy, cybernetics, information theory, computer science) that are applied to biological simulations and model building. Immunology has joined these efforts, and the question posed here is whether the discipline will remain committed to its theoretical concerns framed by the notions of protecting an insular self, an entity (...) demarcated from its environment, or will shift its focus of interest to a wider context. An ecological perspective emphasizes the interchange between the organism and its environment, the processing of information, and the regulation arising from responses to this larger context. Moving from the first attempts at modeling the immune system as a closed network, immunologists have joined the general interest in systems analysis, and that move might portend a significant shift to an open, more holistic consideration of immune regulation. *Received December 2006; revised August 2007. †To contact the author, please write to: Center for Philosophy and History of Science, Boston University, 745 Commonwealth Ave., Boston, MA 02215; e-mail: [email protected].
