Contemporary architecture is increasingly grounded in science and mathematics. Architectural discourse has shifted radically from the sometimes disorienting Derridean deconstruction, to engaging scientific terms such as fractals, chaos, complexity, nonlinearity, and evolving systems. That's where the architectural action is -- at least for cutting-edge architects and thinkers -- and every practicing architect and student needs to become conversant with these terms and know what they mean. Unfortunately, the vast majority of architecture faculty are unprepared to explain them to students, (...) not having had a scientific education themselves. Here is an architecture book by an architect/scientist, just in time to help architects in the new millennium. Alexander discusses many of the scientific terms arising in cutting-edge architecture, and explains them to those who don't have scientific training or advanced mathematical knowledge. We find discussions of the evolution of forms; the importance of process in design; iteration; genetic algorithms; sequences of transformations; different levels of scale (i.e. fractals); etc. They are explained here by an architect who is also a scientist, because he wants to change the way architects think and build. Alexander is not merely popularizing other scientists' results and making them accessible to architects: he is in fact presenting new and original scientific work that ties many of these concepts together in a way that will be useful to architects.

This text addresses the problems of complex systems in understanding natural phenomena and the behaviour of systems related to human activity, from a science and humanities perspective. It discusses molecular behaviour and structures, and offers examples of ecological and environmental modelling.

Democracy has been a flawed hegemony since the fall of communism. Its flexibility, its commitment to equality of representation, and its recognition of the legitimacy of opposition politics are all positive features for political institutions. But democracy has many deficiencies: it is all too easily held hostage by powerful interests; it often fails to advance social justice; and it does not cope well with a number of features of the political landscape, such as political identities, boundary disputes, and environmental (...) crises. Although democracy is valuable it fits uneasily with other political values and is in many respects less than equal to the demands it confronts. In this volume prominent political theorists and social scientists present original discussions of such central issues. Democracy's Values deals with the nature and value of democracy, particularly the tensions between it and such goods as justice, equality, efficiency, and freedom. (shrink)

Science communication in online media is a discursive domain where science-related content is often expressed through styles characteristic of popular journalism. This article aims to characterize some dominant stylistic patterns in magazine articles devoted to environmental issues by identifying the devices used to enhance newsworthiness, given the fact that for some readers environmental topics may no longer seem engaging. The analytic perspective is an adaptation of the newsworthiness framework that has been applied in news discourse studies. (...) The material is a sample of the 38 most-read environment-oriented articles in the online version of the international science magazine New Scientist collected between late 2013 and late 2014. The articles are analysed qualitatively to show the instantiations of such newsworthiness criteria as novelty and superlativeness, timeliness and impact, negativity and positivity as well as other strategies aimed at engaging the readers: rationalization and speculation, direct address and conversational style. The analysis reveals how, in this case study, science communication is turned into infotainment and considers the implications of this discursive shift for the public understanding of environmental science.

The responses of a convenience sample of 83 secondary preservice and preeducation students in three university classes were compared to each other and to a national sample of 1,492 adults on a national poll of science knowledge. The results of the data analyses using simple ANOVA and two-tailed t tests indicated that preservice secondary science teachers in a secondary science methods class are significantly more science literate than preeducation majors and the na tional sample. They were (...) not significantly more science literate than preservice and in-service science teachers in an environmental science methods class. Chemistry majors were significantly more science lit erate than other science and health majors. Additional comparisons between males and females, graduates and undergraduates, and older and younger (younger than 28) students indicated males, graduates, and older students are significantly more science literate than females, undergraduates, and younger students.

This paper details many ways in which this input has been inadequate, especially during the Bush administration. It also recounts examples of successful use of scientific inputs, and discussed the reasons for both successes and failures. Then it proposes ways to accomplish the critical task of seeing to it that science is properly considered in the policy process.

The article discusses the uncertainty in climate science and the problem this poses for policymakers confronting mitigation policy costs in the U.S. The reasons legitimate scientific uncertainty becomes magnified in the political arena are highlighted. This uncertainty results from the rapid pace of published research, as demonstrated by the paleoclimatology studies in "Nature" and the July 2005 issue of "Science." The author states that the California Air Resources Board seems to refuse to undertake an open reconsideration of the (...) policy implications of its emissions reduction strategy.

Dealing with complex problems often requires argumentative skills that go beyond the natural abilities even of gifted students and lecturers. We sketch how to reconstruct and evaluate arguments and outline how the fostering of argumentative skills is integrated into the curriculum in Environmental Sciences at the Department of Environmental Systems Sciences of ETH Zurich.

In this paper we take a close look at current interdisciplinary modeling practices in the environmental sciences, and suggest that closer attention needs to be paid to the nature of scientific practices when investigating and planning interdisciplinarity. While interdisciplinarity is often portrayed as a medium of novel and transformative methodological work, current modeling strategies in the environmental sciences are conservative, avoiding methodological conflict, while confining interdisciplinary interactions to a relatively small set of pre-existing modeling frameworks and strategies (a (...) process we call crystallization). We argue that such practices can be rationalized as responses in part to cognitive constraints which restrict interdisciplinary work. We identify four salient integrative modeling strategies in environmental sciences, and argue that this crystallization, while contradicting somewhat the novel goals many have for interdisciplinarity, makes sense when considered in the light of common disciplinary practices and cognitive constraints. These results provide cause to rethink in more concrete methodological terms what interdisciplinarity amounts to, and what kinds of interdisciplinarity are obtainable in the environmental sciences and elsewhere.

In this essay, I consider three philosophical issues that arise in the environmental sciences. First, these sciences depend on mathematical models and simulations which are highly idealized and are coupled with very uncertain data. Why should we trust these models and simulations? Second, in standard hypothesis testing, the burden of proof is in favor of the null hypothesis which claims some causal factor has no effect. The alternative hypothesis is accepted only when the likelihood of the null hypothesis is (...) very low. Recently, some have argued that we should minimize Type II errors (not rejecting a false null) rather than Type I errors (rejecting a true null) given the environmental risks involved. I consider arguments for shifting this burden of proof when possible environmental harms are significant. Finally, in debates over global climate change, much is made of the apparent consensus concerning the effects of human induced greenhouse gas emissions on average surface temperatures. However, scientific methods are structured around dissent and criticism. Is consensus-based science orthogonal are even harmful to science? (shrink)

I critically assess Don Marietta’s thesis that obligations are not dictates of reason but rather are imbedded in a person’s “world view.” The notion of “a view of the world” is both vague and leads to consequences common to all forms of subjectivism in ethics, since world views can and sometimes do vary from person to person. Marietta cannot avoid these consequences by arguing that some views of the world are “more reasonable” than others, since counting rationality as an appropriate (...) basis for choosing between world views is itself to favor a particular view of the world. Neither then can Marietta consistently argue for the preferability of a world view which grounds our obligations regarding the ecosystem in environnlental science. Given his general position, this can only tell us what he prefers, not whatis preferable. (shrink)

Global environmental science, in its current configuration as predominantly interdisciplinary earth systems analysis, owes its existence to technological development in three respects. (1) Environmental impacts of globalization of corporate and military industrial development linked to widespread use of new technologies prompted investigation of ways to understand and anticipate the global nature of such impacts. (2) Extension of the reach of technology itself demands extension of attempts to anticipate and control the environment in which the technology is to (...) function. Thus as the reach becomes global, the environment in question is also global. (3) Such global studies cannot get far without the development of command, control and information technologies (computers, satellites, automated remote sensing devices) which are crucial for data gathering, storage, and analysis and for the simulation modeling, crucial to theory testing and prediction. This network of dependence on technological development gives the global environmental sciences a rather distinctive epistemological profile, one in which some distinctions that we had thought were clear, on the basis of models of classic laboratory sciences (such as those between experiment and deduction or representation and instrument), turn out to be far from clear. In consequence there needs to be a careful evaluation of the extent to which, or the ways in which, these sciences can provide bases for policy decisions. (shrink)

Biodiversity is a term easily applied in different and differing contexts. At first glance it seems to be a biological concept, defined and used in the realm of biological theory, serving for the description of particular aspects of the human and non-human environment. In this sense biodiversity even found its way into the texts of international conventions: “Biological diversity means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic systems and the ecological complexes (...) of which they are part; this includes diversity within species, between species and of ecosystem.” [Harper and Hawksworth (1995)] But despite this clear and distinct definition, the intension of the term BD seems to be ambiguous. This is true for the single aspects of the definition itself, for example, the discussion over “what is a species?” took place in biology during the last 200 years and it is far from being finished [Claridge et al. (1997) Species]. This discussion asks not only for the “correct” biological definition of the term, but at the same time the methodological status of this term is in question. The result of this situation can be seen in the existence of at least 10–20 different definitions, considering biological as well as methodological aspects [Bachmann (1998) Theor Biosci 117:213–230]. Setting aside the fundamental scientific problems even the application of the term, its parametrisation and finally its relevance for biological theory-building is subject matter of controversies. The same is true for further particles of the definition, e.g. the term “ecosystem”, “complexity”, “gen”, “organisms”, etc. The intensity of the debate contrasts in a peculiar way to the reaction of (non-evolutionary) biologists, insofar as the biological research seems to be untouched by the irritating results of the debate itself. Referring to this strange situation, the aim of our article is a reconsideration of the term “biodiversity”. From an epistemological point of view it can be shown that a definition of biodiversity is possible which does not refer to biological knowledge and know-how—at least in its very first steps. Biodiversity then turns out to be a metaphor for specific aspects of societal organisation, the structuration and reproduction of nature-society relations within societies, and not for biological facts at all.

Interdisciplinarity is often framed as crucial for addressing the complex problems of contemporary society and for achieving new levels of innovation. But while science policy and institutions have provided a variety of incentives for stimulating interdisciplinary work throughout Europe, there is also growing evidence that some aspects of the academic system do not necessarily reward interdisciplinary work. In this study, we explore how mid-career researchers in an environmental science research center in Sweden relate to and handle the (...) distinct forms of uncertainty that arise from conflicting institutional and policy impulses. Our material suggests that interdisciplinary academics are often confronted with and at times themselves operate with a surprisingly dichotomous, value-laden view of their research practice. Disciplinarity is primarily associated with the ideals of scientific rigor, while interdisciplinarity becomes conflated with application-oriented work and a lack of ‘theory.’ We also draw attention to the underlying practical dynamics that reproduce this tension and entangle it with the very process of academic socialization. Specifically, we analyze the ambivalent consequences of the various work-arounds that researchers rely on to carve out opportunities for ongoing interdisciplinary research within heterogeneous funding landscapes. These tactics turn out to be undermined by the overriding normative power of formal career incentives at universities, which continue to emphasize the ideals of the individual high-performing academic who publishes in disciplinary journals and attracts the most selective grants. Under such circumstances, the work-arounds themselves become an insidious mechanism that allows researchers to stay in academia but systematically marginalizes their voices and epistemic ambitions in the process.

Environmental problems often outstrip the abilities of any single scientist to understand, much less address them. As a result, collaborations within, across, and beyond the environmental sciences are an increasingly important part of the environmental science landscape. Here, we explore an insufficiently recognized and particularly challenging barrier to collaborative environmental science: value pluralism, the presence of non-trivial differences in the values that collaborators bring to bear on project decisions. We argue that resolving the obstacles (...) posed by value pluralism to collaborative environmental science requires detecting and coordinating the underlying problematic value differences. We identify five ways that a team might coordinate their problematic value differences and argue that, whichever mode is adopted, it ought to be governed by participatory virtues, pragmatic resolve, and moral concern. Relying on our experiences with the Toolbox Dialogue Initiative, as well as with other dialogical approaches that support team inquiry, we defend the claim that philosophical dialogue among collaborators can go a long way towards helping teams of environmental scientists and fellow travelers detect their problematic value differences. Where dialogical approaches fare less well is in helping teams coordinate these differences. We close by describing several principles for augmenting philosophical dialogue with other methods, and we list several of these methods in an appendix with brief descriptions and links for further learning. Overall, the article makes three main contributions to the research collaboration and values in science literatures: It deepens our understanding of problematic value pluralism in team science; It provides actionable guidance and methods for improving values-oriented philosophical dialogue interventions; and It demonstrates one way of doing engaged philosophy.

This paper examines how ethically significant assumptions and values are embedded not only in environmental policies but also in the language of the environmental sciences. It shows, based on three case studies associated with contemporary pollution research, how the choice of scientific categories and terms can have at least four ethically significant effects: influencing the future course of scientific research; altering public awareness or attention to environmental phenomena; affecting the attitudes or behavior of key decision makers; and (...) changing the burdens of proof required for taking action in response to environmental concerns. The paper argues that deliberative forums, research-ethics training, and conceptual work by environmental philosophers could all promote more ethically sensitive responses to these features of scientific language.

Professionals in environmental fields engage with complex problems that involve stakeholders with different values, different forms of knowledge, and contentious decisions. There is increasing recognition of the need to train graduate students in interdisciplinary environmental science programs in these issues, which we refer to as “social ethics.” A literature review revealed topics and skills that should be included in such training, as well as potential challenges and barriers. From this review, we developed an online survey, which we (...) administered to faculty from 81 United States colleges and universities offering IESPs. Respondents overwhelmingly agreed that IESPs should address values in applying science to policy and management decisions. They also agreed that programs should engage students with issues related to norms of scientific practice. Agreement was slightly less strong that IESPs should train students in skills related to managing value conflicts among different stakeholders. The primary challenges to incorporating social ethics into the curriculum were related to the lack of materials and expertise for delivery, though challenges such as ethics being marginalized in relation to environmental science content were also prominent. Challenges related to students’ interest in ethics were considered less problematic. Respondents believed that social ethics are most effectively delivered when incorporated into existing courses, and they preferred case studies or problem-based learning for delivery. Student competence is generally not assessed, and respondents recognized a need for both curricular materials and assessment tools. (shrink)

In the twenty-first century, there has been a resurgence of ecologically conscious art among artists using new technologies. Like Eco-art, this recent movement, which might be called Eco-media, is interdisciplinary. Eco-media is heavily influenced by developments in environmental science, in particular developments in remote imaging and other kinds of remote Earth sensing (for example, the widespread use of satellite imaging and GPS) and developments in computer modelling (for example, detailed global models of climate that not only model the (...) physics of the Earth and solar system, but also explore the chemistry and biology of the Earth). This article will discuss developments in media art related to the computerized interpretation of complex data sets describing and modelling the natural world. It will explore work that has historically straddled artistic and scientific development, specifically Marey's work in the nineteenth century in photography and motion pictures and give examples of artists who are working in the area in-between art and science today. It will also discuss connections between this work and the historical Romantic sublime and the political dimension of this work as advocating for the preservation of the natural world, and give examples of some of the author's artworks in this area.

Decision makers addressing the ecological crisis face the challenge of considering complex ecosystems in their socioeconomic decisions. Complementary to ecological sciences, other scientific frameworks, grouped under the umbrella term environmental sciences, offer decision makers the opportunity to pursue sustainable paths. Because the environmental sciences are drawn from different branches of science, environmental ethics must go beyond the legacy of ecology and the life sciences to describe the contribution of scientific knowledge to addressing the ecological crisis. In (...) this regard, I analyze and compare three environmental sciences based on their seminal articles: Conservation Biology, Sustainability Science, and Sustainability Economics. My analysis shows that conservation biology and sustainability economics share strong similarities despite their different disciplinary backgrounds (life _versus_ social sciences). Both seek to contrast a biocentric and an anthropocentric perspective. The goal of sustainability is therefore understood as a balance that must be found between these two perspectives. If the issue of balancing human and non-human interests is still relevant to sustainable science, it is more likely to take place in an ecocentric perspective based on alternative ontological and normative prescriptions. Based on this analysis, I distinguish between ‘proscriptive value-based’ scientific work that cannot be used for policy advice but is flexible to different value systems, and ‘prescriptive value-based’ scientific work that can be used for policy advice but is fixed within a given value system. Conflicting recommendations from environmental scientists therefore result from the coexistence of multiple ‘prescriptive value-based’ scientific approaches based on different conceptions of the relationship between humans and nature.

In 1960 Sir Solly Zuckerman proposed the idea of an interdisciplinary department of ‘environmental sciences’ (ENV) for the newly established University of East Anglia (UEA). Prior to this point, the concept of ‘environmental sciences’ was little known: since then, departments and degree courses have rapidly proliferated through universities and colleges around the globe. This paper draws on archival research to explore the conditions and contexts that led to the proposal of a new and interdisciplinary grouping of sciences by (...) Zuckerman. It argues that the activities of Zuckerman and other scientists in Britain during the Second World War and in the post-war period helped to create fertile conditions for a new kind of scientific authority to emerge as a tool of governance and source of policy advice. In particular, the specific challenges of post-war Britain – as addressed through scientific advisers and civil servants – led to the ‘environment’ becoming both the subject of sustained scientific study and an object of concern.

Post-normal science is presented by its proponents as a new way of doing science that deals with uncertainties, value diversity or antagonism, and high decision stakes and urgency, with the ultimate goal of remedying the pathologies of the global industrial system for which, according to Funtowicz and Ravetz, existing science forms the basis. The authors critically examine whether PNS can fulfill this claim in the light of empirical and theoretical work on politics and policy making. The authors (...) credit PNS as an innovative frontrunner in raising important issues regarding the limited problem-solving capacity of ‘‘normal science’’ and ‘‘professional consultancy.’’ Yet, the authors notice that PNS lacks important considerations about the governance of problems and aspects of participatory and deliberative democracy. PNS in effect implies that methodological ‘‘ratiocination’’ would prevail over political deliberation and democratic interaction and that merely changing scientific input in public policy making would have the power to change its outcomes. This scientistic hubris can be traced back to PNS’s origin in concerned scientists’ activism, which in effect accessed the political arena through the scientific entrance. The authors conclude that the art of politics needs to come back into the discussion on environmental problems if societal change is to occur. (shrink)

Chronicles humanity's long quest to understand its own origins and the connectedness of all life on Earth.

This article explores how scientists adapt to a changing climate. To do this, we bring examples from a case study of salmon habitat restorationists in the Columbia River Basin into conversation with concepts from previous work on change and stability in knowledge infrastructures and scientific practice. In order to adapt, ecological restorationists are increasingly relying on predictive modeling tools, as well as initiating broader changes in the interdisciplinary nature of the field of ecological restoration itself. We explore how the field (...) of ecological restoration is shifting its conceptual gaze from restoring to past, historic baselines to anticipating a no-analog future and consider what this means in terms of understanding the adaptive capacity of knowledge infrastructures and epistemic communities more broadly. We argue that identifying how scientists themselves conceptualize drivers of change and respond to these changes is an important step in understanding what adaptive capacity in science might entail. We offer these examples as a provocation for thinking about “adaptive epistemologies” and how adaptation by scientists themselves can facilitate or hinder particular environmental or sociotechnical futures.

The idea of ‘modal fields’ is inspired by regional and pluralistic ontologies, which were sketched and developed by Hegel, Husserl and especially Nicolai Hartmann. It suggests that the world is structured by spheres which are not reducible to each other, and that modal fields denote the scope of real possibilities inside the spheres. It is, for example, possible to distinguish between physical, biological, ecological, economic and technological possibilities/modal fields. It is also possible to define, for the purpose of scientific research, (...) very specific modal fields. For example, we can ask “What are the physiological or social possibilities of ants?”, or “What are the social and psychological possibilities of fundamental religious sects?” It is possible to apply this ontological theory to philosophy of science in order to clarify the scope and limits of causal explanations and hermeneutic understanding especially in human and environmental sciences. In general, this ontological theory serves as a fruitful basis for the kind of scientific thinking which is open to counterfactuals and possibilities and which considers deterministic causal thinking too restricted for human and environmental sciences. On the other hand, this theory avoids the individualistic and anthropocentric presuppositions of hermeneutical understanding, connecting it to the real subjective and objective possibilities in a certain historical situation.

Argumentation schemes have played a key role in our research projects on computational models of natural argument over the last decade. The catalogue of schemes in Walton, Reed and Macagno’s 2008 book, Argumentation Schemes, served as our starting point for analysis of the naturally occurring arguments in written text, i.e., text in different genres having different types of author, audience, and subject domain, for different argument goals, and for different possible future applications. We would often first attempt to analyze the (...) arguments in our corpora in terms of those schemes, then adapt schemes as needed for the goals of the project, and in some cases implement them for use in computational models. Among computational researchers, the main interest in argumentation schemes has been for use in argument mining by applying machine learning methods to existing argument corpora. In contrast, a primary goal of our research has been to learn more about written arguments themselves in various contemporary fields. Our approach has been to manually analyze semantics, discourse structure, argumentation, and rhetoric in texts. Another goal has been to create sharable digital corpora containing the results of our studies. Our approach has been to define argument schemes for use by human corpus annotators or for use in logic programs for argument mining. The third goal is to design useful computer applications based upon our studies, such as argument diagramming systems that provide argument schemes as building blocks. This paper describes each of the various projects: the methods, the argument schemes that were identified, and how they were used. Then a synthesis of the results is given with a discussion of open issues. (shrink)

Deep ecology is examined from the perspective of scientific ecology. Two norms, self-realization and biocentric equality, are considered central to deep ecology, and are explored in brief. Concepts of scientific ecology that seem to form a bridge to these norms are ecological hierarchical organization, the exchange of energy, material and information, and the development of species within ecosystems and the biosphere. While semantic problems exist, conceptually it appears that deep ecology norms can be interpreted through scientific ecology.

The paper starts with the assumption that the Precautionary Principle (PP) is one of the most important elements of the concept of sustainability. It is noted that PP has entered international treaties and national law. PP is widely referred to as a central principle of environmental policy. However, the precise content of PP remains largely unclear. In particular it seems unclear how PP relates to science. In section 2 of the paper a general overview of some historical and (...) systematic features of PP are presented. In section 3 a specific case is discussed in greater detail. It is claimed that the escape of farmed salmon from fish cages in the Sea, and its eventual invasion of the breeding places of the wild salmon up the rivers, must be regarded a proper case for applying PP. Yet there is no single PP-strategy. Instead, four different strategies are presented, and all of them can be regarded precautionary strategies in the light of PP. The choice between these strategies is based upon personal values. In section 4 of the paper a general analysis is given which relates these different value perspectives to basic differences in risk aversion, which in turn are related to differing conceptions of nature and/or society. In the concluding section 5 some general consequences of the foregoing analysis are outlined. (shrink)
