The role of coffee in the land usepatterns and decisions of eastern Chiapas looms as akey ingredient in the social and political relationsof this conflicted area. Data from the municipios of Ocosingo, Altamirano, and Las Margaritas – threedistricts generally associated with the January 1994uprising – reveal similarities and distinctdifferences in land use patterns involving coffee. Theintroduction and spread of coffee, as well as themarket and production changes related to this export-oriented sector can be linked to the colonists whosettled (...) this remote region over the past severaldecades. The dynamics between grassrootscampesino producer organizations and the state'snow-defunct National Coffee Institute (INMECAFE)helped set the stage for the economic challenges thatfell full force upon the residents in the area in 1994and beyond.

This article examines land-use changes by large-scale plantations in Ethiopia and evaluates the impacts thereof on soil organic carbon, micronutrients and bulk density. Remote sensing analysis and field research activities were undertaken at four large-scale plantation projects in Benshanguel Gumuz, Gambella, and Oromia regional states. Results show that the projects largely involved the conversion of both closed and open to closed forests and grasslands, which in turn reduced soil carbon stock and micronutrient levels and increased soil compaction. We argue (...) that unless appropriate soil management activities and impact mitigation strategies are adopted by plantation proponents, these land-use changes will pose a serious threat to the long-term economic viability and sustainability of plantation agriculture in Ethiopia. This could undermine long-term ecosystem health and national food security. (shrink)

It is important to re-engage public health professionals, after an absence of almost a half a century, in the issues of land development and community design. Resources should be devoted to processes that directly engaged diverse communities in defining their idea of good public health. In Michigan, within demographic communities, the idea or definition is slightly different, but an agreement was reached that activities should be developed around four basic environmental areas: food, air, water, and land use. Resource (...) teams were developed around each of these areas, and an attempt was made to describe the current status of environmental conditions and identify major health problems. The community was engaged in a dialogue and a strategy for improvements was developed. The Michigan Land Use Resource Team identified land trends, described water and air quality, and even mapped automobile injuries, including pedestrian injuries and deaths. (shrink)

Image segmentation in land cover regions which are overlapping in satellite imagery, is one crucial challenge. To detect true belonging of one pixel becomes a challenging problem while classifying mixed pixels in overlapping regions. In current work, we propose one new approach for image segmentation using a hybrid algorithm of K-Means and Cellular Automata algorithms. This newly implemented unsupervised model can detect cluster groups using hybrid 2-Dimensional Cellular-Automata model based on K-Means segmentation approach. This approach detects different land (...) use land cover areas in satellite imagery by existing K-Means algorithm. Since it is a discrete dynamical system, cellular automaton realizes uniform interconnecting cells containing states. In the second stage of current model, we experiment with a 2-dimensional cellular automata to rank allocations of pixels among different land-cover regions. The method is experimented on the watershed area of Ajoy river (India) and Salinas (California) data set with true class labels using two internal and four external validity indices. The segmented areas are then compared with existing FCM, DBSCAN and K-Means methods and verified with the ground truth. The statistical analysis results also show the superiority of the new method.

it is sometimes said that one of Kant’s decisive advances over his predecessors was to have anticipated Frege’s functional theory of concepts, along with its corollary that a concept has significance only in the context of the whole proposition.1 Kant is said to break with a tradition that held that there is a self-standing species of concept-use—called apprehensio simplex, or the conceiving of an idea—in which one represents objects by having a concept before one’s mind, independently of connecting it with (...) other concepts in judgment.2 Since Kant’s use of ‘judgment’ covers what Frege calls judging as well as what he calls grasping a thought, the idea is that according to Kant the only way for a thinker to use a..

Competition for land is increasing as demand for multiple land uses and ecosystem services rises. Land regulation of the principles of landscape ecology is necessary to develop more sustainable approaches to land use planning. The research evaluated the present land patterns and determined best practices for its regulation of Dongwang Township in Quyang County, located in the Taihang Mountain area of Hebei Province, China. The research used the landscape ecology theory to construct an index system (...) for landscape pattern analysis based on the GIS and Fragstats 3.3 software. In this study, we examined the specific reasons that landscape ecology is superior to traditional methods in land consolidation planning and design, which is conducive to the comprehensive development of land ecological benefits. Landscape ecological planning can effectively reduce landscape fragmentation and improve intensive management. The result found that the descending order of the Shannon index was current landscape, landscape ecological planning, and traditional planning. Landscape ecological planning could protect the natural diversity than traditional planning. Landscape ecological planning enables the creation of long corridors, with higher densities and connectivity and lower average corridor widths than traditional planning. Besides, it can improve ecological service function values in the study area to varying degrees, thus discouraging residents from limiting themselves to grain production. This research has great potential to improve the visibility of ecosystem services in local land use planning and, thus, to improve the ecological functioning of future landscapes. (shrink)

In this article, drawing on the discursive psychology of Rom Harré, we show how mapping the exchange of words among people might disclose a complex reality; not merely that which farmers explicitly talk ‘about’ but the reality implicitly at stake within the communication. More specifically, we show how discourses involving modern farmers reveal an underlying placing in an abstract space, having sub-spaces defined by the life-orientation, sense of self and according self-positioning of modern people. In this way, we construct a (...) road map of a set of ‘individualities’ characterizing the life of modern farmers: an individuality of citizenship, an individuality of geographies and an individuality of experience. Consequently, farmers face the problem that this multiplicity of individuality prevents them from communicating, as we will call it, univocally in the public by contrast to the univocal voices of other established social groups. We will analyse the structure of that problem by viewing diverse relations between the authority and the authenticity of different partners in the conversation on land use. (shrink)

Winner of the 2014 Edward Goodwin Ballard Award for an Outstanding Book in Phenomenology, awarded by the Center for Advance Research in Phenomenology. -/- Merleau-Ponty and the Paradoxes of Expression offers a comprehensive reading of the philosophical work of Maurice Merleau-Ponty, a central figure in 20th-century continental philosophy. -/- By establishing that the paradoxical logic of expression is Merleau-Ponty's fundamental philosophical gesture, this book ties together his diverse work on perception, language, aesthetics, politics and history in order to establish the (...) ontological position he was developing at the time of his sudden death in 1961. Donald A. Landes explores the paradoxical logic of expression as it appears in both Merleau-Ponty’s explicit reflections on expression and his non-explicit uses of this logic in his philosophical reflection on other topics, and thus establishes a continuity and a trajectory of his thought that allows for his work to be placed into conversation with contemporary developments in continental philosophy. The book offers the reader a key to understanding Merleau-Ponty's subtle methodology and highlights the urgency and relevance of his research into the ontological significance of expression for today's work in art and cultural theory.

Xavier Landes | : In this article, consensus, defined as the consent of all citizens, is argued to be the first best for part of the liberal tradition on political legitimacy. Consensus would be the foundation of the liberal society that, when out of reach, needs to be approximated through, for instance, voting. I build on the timid attempts in political theory at using the theorem of the second best as a tool to settle difficult decision making in applied political (...) theory. More precisely, I defend the view that consensus would be the first best for part of the liberal tradition on political legitimacy. Furthermore, I illustrate how moral, factual, disagreements may create second-best problems, especially in terms of stability. Finally, I spell out some reasons why such problems directly affect a liberal order, on pragmatic grounds. The final purpose is to contribute to the literatures on legitimacy and on the application of the theorem of the second best outside economics. The key idea is to stress that much more work has to be done for “importing” the theorem of the second best into political theory. | : Dans cet article, le consensus, défini comme le consentement de tous les citoyens, est présenté comme remplissant la fonction d’optimum de premier rang [first best] pour une partie de la tradition libérale quant à la légitimité politique. Le consensus fonderait la société libérale qui, lorsque hors d’atteinte, nécessiterait d’être approximer au travers, par exemple, du vote. Je m’appuie sur les timides tentatives en théorie politique d’utiliser le théorème de l’optimum de second rang [second best] comme outil pour résoudre des prises de décision difficiles en théorie politique appliquée. Plus précisément, je défends l’idée que le consensus serait l’optimum de premier rang pour une partie de la tradition libérale quant à la légitimité politique. De plus, j’illustre comment les désaccords moraux, factuels peuvent créer des problèmes d’optimum de second rang, en particulier en termes de stabilité. Enfin, j’expose quelques raisons pour lesquelles de tels problèmes affectent directement un ordre libéral, d’un point de vue pragmatique. Le but final est de contribuer aux littératures sur la légitimité et sur l’application du théorème d’optimum de second rang à l’extérieur des sciences économiques. L’idée principale est de souligner qu’il reste beaucoup de travail afin d’« importer » le théorème d’optimum de second rang en théorie politique. (shrink)

Many students ask, 'What is the point of learning formal logic?' This book gives them the answer. Using the methods of deductive logic, Nelson Lande introduces each new element in exquisite detail, as he takes students through example after example, proof after proof, explaining the thinking behind each concept. Shaded areas and appendices throughout the book provide explanations and justifications that go beyond the main text, challenging those students who wish to delve deeper, and giving instructors the option of confining (...) their course to the basics, or expanding it, when they wish, to more rigorous levels. Lande encourages students to think for themselves, while at the same time providing them with the level of explanation they need to succeed. It is a rigorous approach presented in a style that is informal, engaging, and accessible. Students will come away with a solid understanding of formal logic and why it is not only important, but also interesting and sometimes even fun. It is a text that brings the human element back into the teaching of logic. --Hans Halvorson, Princeton University. (shrink)

Land use planning, based in either traditional liberalist philosophy or the emerging pragmatist philosophy formalizes an anthropocentric, reductionist division within itself: between nature (land) and society (use), ignoring the socially constructed character of both terms. Representations of nature become political issues mediated through the planning system, with the various actants and their networks attempting to exert power over others in order to influence the outcome. Based on a theoretical understanding of, by deconstructing the different representations of nature/the environment (...) and identifying the discourses and narratives invoked by participants in land use planning decisions, we can better understand how nature continues to be exploited by humans in their own interests.

The beginning of the COVID-19 pandemic offers a unique case study for understanding conceptual and linguistic propagation. In early 2020, scientists, politicians, journalists, and other public figures had to, with great urgency, propagate several public health-related concepts and terms to every person they could. This paper examines the propagation of coronavirus and social distancing and develops a framework for understanding how the language used to express a notion can help or hinder propagation. I argue that anyone designing a representational device (...) for propagation needs to appreciate the three-way causal relationship between language, people’s mental representations, and the extramental world. Using this framework, I explore what makes “social distancing” a bad name for social distancing and why it is unproblematic that “coronavirus” is a scientifically loose way of speaking about the virus. Through this and further study of the many historical examples of linguistic and conceptual propagation, conceptual engineers can better understand the complex challenges facing people who want to propagate representational devices.

Xavier Landes | : Happiness has become a central theme in public debates. Happiness indicators illustrate this importance. This article offers a typology of the main challenges conveyed by the elaboration of happiness indicators, where happiness can be understood as hedonia, subjective well-being, or eudaimonia. The typology is structured around four questions: what to measure?—i.e., the difficulties linked to the choice of a particular understanding of happiness for building an indicator; whom to include?—i.e., the limits of the community monitored by (...) such an indicator; how to collect the data?—i.e., the difficulties stemming from objective and subjective reporting; what to do?—i.e., the concerns about the use of happiness indicators in public policy. The major points of normative contention are discussed for each of these dimensions. The purpose of this article is to contribute in a constructive manner to happiness research by offering an overview of some major philosophical and political challenges of building happiness indicators. The conclusion underlines the importance of the strategy of diversification- hybridization, which consists in setting a variety of indicators or composite indicators that articulate different understandings of happiness. It is stressed that happiness indicators raise democratic and institutional issues with which normative thinkers should deal. | : Le bonheur est devenu un thème central dans les débats publics. Les indicateurs de bonheur illustrent cette importance.

La typologie est structurée autour de quatre questions : 1) que mesurer?, où sont en jeu les difficultés liées au choix d’une compréhension particulière du bonheur pour construire un indicateur; 2) qui inclure?, c’est-à-dire comment tracer les limites de la communauté morale qui est l’objet d’un tel indicateur; 3) comment collecter les données?, où on interroge les difficultés propres aux techniques subjectives et objectives de collecte de données; 4) que faire?, où on soulève l’enjeu des craintes quant à l’usage d’indicateurs de bonheur dans les politiques publiques.

Philosophical discussions on causal inference in medicine are stuck in dyadic camps, each defending one kind of evidence or method rather than another as best support for causal hypotheses. Whereas Evidence Based Medicine advocates the use of Randomised Controlled Trials and systematic reviews of RCTs as gold standard, philosophers of science emphasise the importance of mechanisms and their distinctive informational contribution to causal inference and assessment. Some have suggested the adoption of a pluralistic approach to causal inference, and an inductive (...) rather than hypothetico-deductive inferential paradigm. However, these proposals deliver no clear guidelines about how such plurality of evidence sources should jointly justify hypotheses of causal associations. We here develop such guidelines by first giving a philosophical analysis of the underpinnings of Hill’s viewpoints on causality. We then put forward an evidence-amalgamation framework adopting a Bayesian net approach to model causal inference in pharmacology for the assessment of harms. Our framework accommodates a number of intuitions already expressed in the literature concerning the EBM vs. pluralist debate on causal inference, evidence hierarchies, causal holism, relevance, and reliability.

The assumption that philosophers rely on intuitions to justify their philosophical positions has recently come under substantial criticism. In order to protect philosophy from experimental findings that suggest that intuitions are epistemically problematic, a number of metaphilosophers have argued that intuitions play no substantial epistemic role in philosophy. This paper focuses on attempts to deny intuitions’ epistemic role through exegetical analysis of original thought experiments. Using Deutsch’s particularly well-developed exegesis of Gettier’s 10 coin case as an exemplar of this method, (...) I examine the challenges the strategy faces. I argue that intuition denial fails to provide a satisfactory account of how verdicts of thought experiments are justified. Instead, it commits intuition deniers to the conclusion that the arguments of Gettier, Kripke, Thomson, and others are bad arguments. As a result, rather than defusing challenges to the case method raised by experimental philosophers, intuition denial ultimately leads to the same troubling conclusion – that philosophers hold their positions on bad grounds.

Speakers of English have available a set of terms dedicated to doing individual self-reference: `I' and its grammatical variants, `me', `my', `mine', etc. Speaker selection of other than these dedicated terms may invite special attention for what has prompted their use. This article draws on field recordings of talk-in-interaction in which speakers use `third-person' reference forms when speaking about themselves. We show that third-person forms are recurrently used for representing the views of someone else. We also show how — by (...) drawing on resources such as the distinction between recognitional and non-recognitional person reference forms, and on category bound attributes — the particular third-person term selected can be fitted to and thereby contribute to the action a speaker is implementing through their turn at talk.

Objective Bayesianism says that the strengths of one’s beliefs ought to be probabilities, calibrated to physical probabilities insofar as one has evidence of them, and otherwise sufficiently equivocal. These norms of belief are often explicated using the maximum entropy principle. In this paper we investigate the extent to which one can provide a unified justification of the objective Bayesian norms in the case in which the background language is a first-order predicate language, with a view to applying the resulting formalism (...) to inductive logic. We show that the maximum entropy principle can be motivated largely in terms of minimising worst-case expected loss. (shrink)

Although Maxwell theory is O(3,1)-covariant, electrodynamics only transforms invariantly between Lorentz frames for special forms of the field, and the generator of Lorentz transformations is not generally conserved. Bérard, Grandati, Lages, and Mohrbach have studied the O(3) subgroup, for which they found an extension of the rotation generator that satisfies the canonical angular momentum algebra in the presence of certain Maxwell fields, and is conserved by the classical motion. The extended generator depends on the field strength, but not the potential, (...) and so is manifestly gauge invariant. The conditions imposed on the Maxwell field by the algebra lead to a Dirac monopole solution.In this paper, we study the generalization of the Bérard, Grandati, Lages and Mohrbach construction to the full Lorentz group in N dimensions. The requirements can be maximally satisfied in a three-dimensional subspace of the full Minkowski space; this subspace can be chosen to describe either an O(3)-invariant space sector, or an O(2,1)-invariant restriction of spacetime. The field solution reduces to the Dirac monopole found in the nonrelativistic case when the O(3)-invariant subspace is selected. When an O(2,1)-invariant subspace is chosen, the field strength can be associated with a Coulomb-like potential of the type A μ(x) = n μ/ρ, where ρ = (x μ x μ)1/2, similar to that used by Horwitz and Arshansky to obtain a covariant generalization of the hydrogen-like bound state. In the presence of these fields, which are determined entirely by symmetry considerations, without reference to a source equation, the extended generator is conserved under classical relativistic system evolution.

This paper discusses the discrete symmetries of off-shell electromagnetism, the Stueckelberg–Schrodinger relativistic quantum theory and its associated 5D local gauge theory. Seeking a dynamical description of particle/antiparticle interactions, Stueckelberg developed a covariant mechanics with a monotonically increasing Poincaré-invariant parameter. In Stueckelberg’s framework, worldlines are traced out through the parameterized evolution of spacetime events, which may advance or retreat with respect to the laboratory clock, depending on the sign of the energy, so that negative energy trajectories appear as antiparticles when the (...) observer describes the evolution using the laboratory clock. The associated gauge theory describes local interactions between events (correlated by the invariant parameter) mediated by five off-shell gauge fields. These gauge fields are shown to transform tensorially under under space and time reflections—unlike the standard Maxwell fields—and the interacting quantum theory therefore remains manifestly Lorentz covariant. Charge conjugation symmetry in the quantum theory is achieved by simultaneous reflection of the sense of evolution and the fifth scalar field. Applying this procedure to the classical gauge theory leads to a purely classical manifestation of charge conjugation, placing the CPT symmetries on the same footing in the classical and quantum domains. In the resulting picture, interactions do not distinguish between particle and antiparticle trajectories—charge conjugation merely describes the interpretation of observed negative energy trajectories according to the laboratory clock.

Trotsky wrote his Terrorism and Communism in 1920, as a response to Karl Kautsky’s book of the same title of the previous year. Trotsky’s aim was to win over, to the side of the Bolshevik view of socialism, the various European socialist political parties. Trotsky’s book is a rare document in the history of political thought. It is a candid and impassioned defense of the Bolshevik view that the period of transition to socialism is incompatible with both individual liberties and (...) democratic institutions as we normally understand them, and requires instead a one-party state with unlimited powers, prepared to use instruments of terror and repression to achieve its goals. In two articles that he wrote in the late 1930s, he elaborated on this view: he sought to provide an explicitly philosophical defense of theBolsheviks’ use of terror and repression.Trotsky’s views merit examination for several reasons: first, because they illuminate the ethical underpinnings of the distinctively Bolshevik view of socialism, and second, because they force one to come to terms with the question of how intelligent, reflective, and decent individuals could have advanced policies that strike us today as ghastly. In this paper I try to piece together Trotsky’s arguments as they bear upon both the Civil War and the immediate postwar period of reconstruction. I also examine criticisms of the policies that Trotsky was defending—criticisms that were advanced by Marxists of such disparate stripes as Kaustky, on the one hand, and Rosa Luxemburg, on the other.

The maximum entropy principle is widely used to determine non-committal probabilities on a finite domain, subject to a set of constraints, but its application to continuous domains is notoriously problematic. This paper concerns an intermediate case, where the domain is a first-order predicate language. Two strategies have been put forward for applying the maximum entropy principle on such a domain: applying it to finite sublanguages and taking the pointwise limit of the resulting probabilities as the size n of the sublanguage (...) increases; selecting a probability function on the language as a whole whose entropy on finite sublanguages of size n is not dominated by that of any other probability function for sufficiently large n. The entropy-limit conjecture says that, where these two approaches yield determinate probabilities, the two methods yield the same probabilities. If this conjecture is found to be true, it would provide a boost to the project of seeking a single canonical inductive logic—a project which faltered when Carnap's attempts in this direction succeeded only in determining a continuum of inductive methods. The truth of the conjecture would also boost the project of providing a canonical characterisation of normal or default models of first-order theories. Hitherto, the entropy-limit conjecture has been verified for languages which contain only unary predicate symbols and also for the case in which the constraints can be captured by a categorical statement of quantifier complexity. This paper shows that the entropy-limit conjecture also holds for categorical statements of complexity, for various non-categorical constraints, and in certain other general situations. (shrink)

Conceptual engineering is the practice of revising concepts to improve how people talk and think. Its ability to improve talk and thought ultimately hinges on the successful dissemination of desired conceptual changes. Unfortunately, the field has been slow to develop methods to directly test what barriers stand in the way of propagation and what methods will most effectively propagate desired conceptual change. In order to test such questions, this paper introduces the masked time-lagged method. The masked time-lagged method tests people's (...) conceptual understanding at two different points in time without their knowledge of being tested, allowing us to measure conceptual revision in action. Using a masked time-lagged design on a content internalist framework, we attempted to revise PLANET and DINOSAUR in online participants to match experts' concepts. We successfully revised PLANET but not DINOSAUR, demonstrating some of the difficulties conceptual engineers face. Nonetheless, this paper provides conceptual engineers, regardless of framework, with the tools to tackle questions related to implementation empirically and head-on. (shrink)

This chapter addresses the problem of ranking available drugs in guideline development to support clinicians in their work. Based on a pragmatic approach to the notion of evidence and a hierarchical view on different kinds of evidence this chapter introduces a decision aid, HiDAD, which draws on the multi criteria decision making literature. This decision aid implements the wide-spread intuition that there are different kinds of evidence with varying degrees of importance by relying on a strict ordinal ordering of kinds (...) of evidence. In order to construct a ranking every pair of drugs is first compared separately on all kinds of evidence. Next, these quantitative comparisons are then aggregated into an overall comparison between drugs based on all the available evidence in a way which avoids that evidence of less importance is trumped by evidence of the higher levels. Finally, these overall comparisons are used to determine the final ranking of drugs which then informs the process of guideline writing. Properties, modifications and applicability of the decision aid HiDAD are discussed and assessed. (shrink)

With the rapid development of the economy, the land use/cover change in the Greater Bay Area has undergone tremendous changes, which have had directly negative effects on ecosystem functions and services. The development of sustainable land use strategies to quantitatively evaluate ecosystem services is required. Based on multitemporal land use data, the equivalent coefficients table method was used to assess the ecosystem service values, and the impact of LUCC on ecosystem services was analyzed. A future land (...) use simulation model and multiscenario simulations were employed to predict land use change in 2030. Our results indicated that the loss of ESVs decreased by 14.29 billion yuan from 2005 to 2020. The spatial distribution of the high-value ecosystem services was concentrated around the peripheral area of the northern regions in the GBA, and those areas had less land use development and human activity. Compared with those in 2020, the total ESVs of the business-as-usual scenario, socioeconomic development scenario, and cultivated protection priority scenario in 2030 decreased, while they increased in the ecological protection priority scenario. In the CPP scenario, regulating, supporting, provisioning, and cultural services increased slightly, but they decreased in the other scenarios. The patterns of LUCC were the main reasons for the decrease in ESVs, such as the loss of land with high ecological value. Additionally, a four-quadrant analysis is introduced to determine which land use simulation will be expected to be adopted by the government. The findings of this study provide valuable information for decision-making and policy development in the coastal zones and for the sustainable management of ecosystems. (shrink)

One of the most striking features observed throughout tropical agricultural frontiers is the extreme variability in land-use strategies from one farmer to the next. This article analyzes the forest conversion process and predominant land uses associated with smallholder settlement expansion in the Amazon frontier. The discussion seeks to increase understanding of the micro and macro-level forces that propel land-use decisions in the Amazon and offer insights about how farmers' land-use decisions may be altered to bring about (...) forms of resource use that are consistent with the constraints and opportunities of the frontier environment. Recognizing that no frontier area can be truly representative of the Amazon as a whole, this article also introduces some detailed evidence from another Amazon country (Ecuador) within a topic that has been previously dominated by research mainly in Brazil. The analysis suggests that to be effective, any policy or technology-based effort on the part of governments or researchers to alter colonist land-use systems must begin to look systematically at the production systems of agricultural colonist populations already present in frontier environments. This knowledge is essential to understand the social and economic factors affecting present land use and choice of technology. It is also important for understanding factors influencing farmers' demand for more optimal systems of land use that are consistent with varying agroecological potentials, demographic situations, and the management capacity of the farmer.

The aim of this paper is to investigate how alternative land ethics of agricultural stakeholders may help explain recent land use changes. The paper first explores the historical development of the land ethic concept in the United States and how those ethics have impacted land use policy and use of private lands. Secondly, primary data gathered from semi-structured interviews of farmers, ranchers, and influential stakeholders are then analyzed using stakeholder analysis methods to identify major factors considered (...) in land use decisions, priorities of factors of each group, and to define relevant mental models describing each group’s view of the land ethic concept. Results show that these stakeholder groups prioritize land use factors qualitatively differently and possess strikingly different land ethics. It is concluded that shifts in stakeholder land ethics have contributed to recent land use changes. Lastly, we discuss how current agricultural policy sends mixed signals about preferred land use and the potential ramifications based on the different land ethics we’ve described. (shrink)

Using land-use models in deliberative planning is promoted as an example of how environmental decision-making can be subject to both: 1) facts about how the interaction between human action and natural processes; and, 2) local perspectives on how land-use planning processes can incorporate normative concerns. This ‘normative’ input is often shaped and limited by the presentation of the modelled facts. This paper, however, shows that the selection and measurement of indicators, the primary outcomes of modelling exercises, are subject (...) to a highly particular assessment, influenced by social factors, political choices and technical limitations. This revised understanding does not invalidate the use of models in participatory planning. But it does open up considerable space for stakeholders in deliberative contexts to question and challenge the evidence-based policy implications of so-called ‘fact-based’ modelling exercises.

Environmentalists in the United States are often confronted by rural landowners who feel that they have the right to do whatever they want with their land regardless of the consequences for other human beings or of the damage to the environment. This attitude is traced from its origins in ancient German and Saxon land use practices into the political writings of Thomas Jefferson where it was fused togetherwith John Locke’s theory of property. This view of land and (...) property rights was most influential in the late nineteenth century after the passage of the Homestead Act in 1862 when it was used in the arguments opposing national parks and nature preservation. Today it remains a formidable obstacle to planning and zoning in rural areas, despite unstated underlying assumptions which are either outdated or false. (shrink)

Historians of science can benefit from thinking more deeply about land. Scholarly emphasis on the geographies of scientific knowledge has become pervasive since the “spatial turn” of the late 1990s. At the same time, the history of science has increasingly intersected with environmental history. Despite these growing connections, historians of science have been slow to embrace a core concern of environmental history: land. While space and place now have a rich literature in the historiography of science, land (...) appears in histories of science in more scattered, incidental ways – largely as a place where science may occur or be applied. More than just a unit of ground, land is analytically connected to a web of questions about labor, property, governance, identity, and environmental change explored by environmental historians, geographers, and political ecologists. This article examines what historians of science – particularly, but not exclusively, historians of the field and environmental sciences – have to gain by taking land more seriously. A reexamination of the Rain Forest Project (1962–1970), a radioecology study initiated by systems ecologist Howard Thomas Odum in what is today El Yunque National Forest, Puerto Rico, serves as a case in point. Viewing this field site as land reframes ecologists’ fieldwork as a form of land use, highlighting its place within regimes of land tenure, its connections with other communities’ uses of the land, and its persistent local legacies.

The Chennai Metropolitan Area (CMA) is a rapidly evolving region that experiences significant changes in land use patterns over time. Analogous to other Indian cities, these transformations are particularly evident in the periphery of Chennai's urban core, where substantial land use shifts have occurred between 2001 and 2021. These changes were assessed utilizing LANDSAT 7 Thematic Mapper (TM), LANDSAT 5 Enhanced Thematic Mapper plus (ETM+) for the years 2001 and 2011, and LANDSAT 8 (OLI) for 2021. This study (...) employs unsupervised classification to investigate major land use/land cover alterations. Findings indicate that CMA has undergone substantial land use modifications over the past two decades. Notably, there has been a marked decline in open land and vegetation due to extensive reclamation for urban and commercial development. The results demonstrate that the area covered by open land and vegetation decreased by 70.23% and 4.56%, respectively, while the built-up area increased by 56%. The study also identified a pattern of urban expansion primarily along the GST road, OMR road, and Thirupati highway. The research further examines land use changes by creating buffer zones at distances of 500 meters, 1 km, 1.5 km, and 2 km. The detailed analysis, along with the spatio-temporal differentiation maps and tables generated through geospatial data, will be invaluable for understanding the growth dynamics of CMA. This information will also support the decision-making process for local planners, stakeholders, and academicians. (shrink)

The last two decades have seen the proliferation of the empirical study of philosophy. This dissertation defends the practice and argues that to understand the way contingent features of the practice of philosophy affect the epistemic standing of philosophers, we need to draw upon a wider and more varied set of empirical data than is sometimes supposed. To explore this, the dissertation focuses on two places where the practices of the discipline of philosophy have an effect on the epistemology of (...) philosophy. -/- First, the dissertation discusses the interaction between notable works of philosophy and their readers. In particular, it critiques the method of defending the epistemic standing of philosophers through careful examination of notable works of philosophy to discern the methods in the text. Ultimately this method is epistemically unmotivated. It is instead far more important to study how people have interacted and reacted to works of philosophy. -/- Second, the dissertation defends the use of lexicography in philosophy.

In this paper I criticize what many economists recommend: namely, that land use regulations should simulate what markets would do were all resources fully owned and freely exchanged. I argue that this “efficiency” approach, even if balanced with equity considerations, will result in commercial sprawl, an environment that consumers pay for, but one that appalls ethical judgment and aesthetic taste.
