VON THUNEN AND THE SIGNIFICANCE OF HIS WORK FOR THE GEOGRAPHY OF AGRICULTURE

Von Thünen's classical model of agricultural location was published in the Soviet Union in Russian translation in 1926, a hundred years after its original publication in Germany, but was soon denounced as a bourgeois theory seeking to optimize location from the point of view of minimizing production costs or maximizing the profit of the entrepreneur. The view that the von Thünen model was not applicable to Soviet conditions was stated as late as 1966 in Vol. V of the Kratkaya geograficheskaya entsiklopediya [Short Geographical Encyclopedia], pp. 196, 525. A Moscow University agricultural geographer, in reassessing the von Thünen model, now points out that its objective of determining optimal production systems for a given set of physical (land quality) and economic (market) conditions is shared by anyone who seeks the most highly cost-effective form of agriculture in a particular setting.     

Aggregate Rent and Surplus Measurement in a von Thünen Model

While theoreticians continue to debate the appropriateness of surplus measurement in a von Thünen crop model, examples of practitioners appealing to such measures can be found. This paper shows that the well known equivalence between aggregate location rent and producers' surplus, extends to the case of a nonhomogeneous transportation system. Specifically a transportation route running through the region improves access to the town and encourages an extension of the production region. Results in the paper show the equilibrium price for the crop (as a function of the quality of the improved route); an equivalence between aggregate rent and the surplus accruing to crop producers; and the existence of an area within which crop production is cut back after the transport route is opened.     

Determinants of Rent from Agricultural Land Around Metropolitan Areas

Three urban determinants of rent from agricultural land around metropolitan areas are incorporated into one rent model. The urban market factor and the transport cost as expressed in the Thünian crop rent equation are discussed in terms of their relevance to metropolitan areas. Then the effects on rent of the urban land market and urban economic change and their relationships with the market factor are examined. Graphic and mathematical expressions of a multideterminant model based on the combined crop system are developed, followed by a discussion on several variations of the model.     

Risk and Agricultural Land Use: A Reformulation of the Portfolio-Theoretic Approach to the Analysis of a von Thünen Economy

This paper extends the portfolio-theoretic approach to a von Thünen economy. It presents the farmer's decision problem as a mean-variance mathematical program, then examines the effect of increasing risk or risk aversion on land use. Risk seeking and the effect of competition on risk taking are also considered.     

Quantum Cultures during the Prehistory of Quantum Gravity: Léon Rosenfeld's Early Contributions to Quantum Gravity

In this paper we consider the prehistory of quantum gravity (1916–1930) from two perspectives. First, we investigate how this research field constituted itself and we propose for the first time a red thread to trace its evolution in this earliest period. Second, we focus on a case study: the earliest work of Léon Rosenfeld. In 1927 he tried to merge wave mechanics with general relativity in the context of a five‐dimensional universe. We describe how Oskar Klein, Louis de Broglie, and Théophile De Donder influenced Rosenfeld's work and analyze how and why Rosenfeld attempted to reconcile Einstein's theory with quantum phenomena. We argue that Rosenfeld investigated for the first time the corrections to a classical space‐time metric generated by a quantum source. As far as we know, Rosenfeld's approach has been largely ignored until today: he himself considered it “an accident.” After having reconsidered its connection with de Broglie's ideas and Rosenfeld's interpretation of the wave function in 1927, we argue that Rosenfeld's work can be interpreted as a first attempt to introduce the pilot‐wave theory in the context of quantum gravity and we infer that this was one of the reasons that ruled it out.     

COMPETITIVE LOCATION UNDER UNCERTAINTY OF COSTS

ABSTRACT. In this paper, we study the centroid problem from competitive location theory for a linear market with uniform demand, assuming that the leader has imperfect information about the follower's fixed and marginal costs. It is shown that the general version of this problem can be formulated as a nonlinear programming problem and the exact solution can be obtained analytically in a special case. A simple strategy is also given for the general problem, and it is proven that this strategy has a guaranteed error bound. It is demonstrated that uncertainty of costs might lead to market failure in the centroid problem, but this disappears if the game is repeated and the firms learn from observing each other's moves. It is also shown that it is possible for the leader to obtain optimal expected profit at a low perceived risk, with only sufficient, and not necessarily perfect, information. These two observations lead to our primary conclusion from the study that although cost uncertainty is a realistic feature of most competitive location models, there are very effective ways of dealing with it.     

Planning in the Zürich Region

This examination of the planning structure within the Canton of Zürich has indicated that many of the problems, such as adequate public transportation, the provision of land for industry, and the preservation of land for recreational use overlap existing political boundaries. The solutions, to be effective, must be carried out in a co-ordinated and integrated fashion among the city, the regional, and the cantonal planning groups. Much is being done at all levels to ensure that the future growth of Zürich and its surrounding region will take place in an orderly, aesthetically satisfying fashion. Certainly many serious problems remain to be solved. Nevertheless, the development of Zürich from a Roman settlement to one of the world's most important industrial, financial, commercial, and cultural centres has been accomplished with a minimum of destruction to the city's beautiful site. The preservation of the natural environment is a blessing for the city's inhabitants, having economic     

MEASURING THE SHAPE OF GEOGRAPHICAL PHENOMENA: A HISTORY OF THE ISSUE

A history of the development of shape indices, going back to some of the earliest formulas proposed by German scholars in the 19th century, groups the various measures in terms of the initial set of data used in their derivation. The author does not approve of indices derived from the perimeter and area of a figure (such as Chorley's lemniscate), linear dimensions and area (Gibbs, Haggett), inscribing and circumscribing circles (Penck, Krumbein), tangential contours and from radial vectors (Boyce and Clark). The author sees greater promise in approaches using the distance from elements of the figure to the perimeter, Bunge's inscribed polygons, and the distance from elements of the figure to the center (Thünen, Blair and Biss). Further work on shape indices is urged with a view to deriving measures that would reflect not only compactness, but also the degree of dissection and contour indentation. The problem is assuming greater significance in light of advances made in picture recognition and processing by computer.     

Class Monopoly Rent and the Redevelopment of Portland's Pearl District

This study examines the role of class monopoly rent in shaping the spatial form and pattern of urban redevelopment processes in the contemporary neoliberal city. Since an initial flourishing literature during the 1970s and 1980s, urban land rent theory has fallen from the analytic radar of critical urban studies since the early 1990s, with the influence of class monopoly rent often considered an aberration of how capitalist real estate markets normally operate, if not rejected. Consequently, class monopoly rent has never been systematically elaborated. Based on an empirical analysis of Portland's Pearl District, this study suggests that the influence of class monopoly rent in contemporary processes of urban redevelopment is far more pervasive than often recognised, representing a “standard institutional practice” that is endemic (rather than aberrational) to the working of neoliberal urban governing regimes, and embeds in the social and physical landscape in a multiplicity of ways.     

A Gravity Model with Variable Coefficients: The EEC Trade with Third Countries

Gravity models with fixed coefficients have been used to explain the trade flows between countries different in income levels and separated by long distances. It is unrealistic to assume that these models can hold with the same parameters across very heterogeneous countries. This paper proposes and estimates an international trade model with variable coefficients constructed by combining Pöy-hönen's and Linnemann's gravity-based trade models via the expansion method.     

STRUCTURAL ESTIMATION OF RESIDENTIAL MOBILITY AND HOUSING TENURE CHOICE*

ABSTRACT. This study is devoted to studying households'decisions to move and whether to rent or own after moving. It employs dynamic discrete choice models which condition households'decisions on their circumstances at every point in time during the length of the observation while accounting for individual heterogeneity. The results show that key dynamic elements, captured by means of lagged dependent variables, as well as household heterogeneity, are significant determinants of the tenure choice and mobility decisions. Moreover, homeowners are found to be responsive to housing market conditions when adjusting their housing stock. Housing-price appreciation is found to discourage renters from becoming homeowners. Finally, our results reject the proportional monetary transaction costs specification suggesting that monetary transaction costs might be fixed.     

AGGLOMERATION VERSUS PRODUCT VARIETY: IMPLICATIONS FOR REGIONAL INEQUALITIES*

ABSTRACT We investigate how cross‐country differences in firms' fixed set‐up costs affect the trade‐off between global efficiency and spatial equity. Our analysis reveals that the standard assumption of symmetry in set‐up costs masks the existence of an interesting effect: the range of available varieties depends on the spatial distribution of firms. In such a setting, where the market outcome leads to excessive agglomeration in the symmetric case, a planner may opt for asymmetric set‐up costs and even more agglomeration. We show that the planner will always favor lower set‐up costs in the large country with more agglomeration when the consumer's marginal preference for variety is high, or with less agglomeration when the consumer's marginal preference for variety is low.     

THE LOCATION THEORY OF THE PLANTATION*

ABSTRACT This paper develops a method for studying noninfinitesimal operational units, with the Thünen location and land use model. With constant returns to scale and perfect divisibility of nonland inputs, all operational units would occupy only a point on the landscape. The present model uses increasing returns to scale to generate large operational units, called “plantations” and studies the comparative statics. The setting of the model is an agricultural operation in which some processing of raw crop must be conducted prior to shipment to market. The processing is assumed to have increasing returns to scale.     

A Theresian Moment: French Catholics and the Spirituality of the Ordinary in the 1930s*

The subject of this article is the lived religion of lay Catholics devoted to the woman described as one of the greatest saints of the modern era, Thérèse of the Child Jesus and the Holy Face, known as Thérèse of Lisieux (1873–1897). It draws on letters written to the Lisieux Carmel in Normandy at the time of the Munich crisis in 1938. Much scholarship on the laity in the interwar years concerns itself with renewal and militancy in the public sphere. By contrast, the body of evidence at hand provides insights into continuities in established forms of devotion and into the religious thinking of the kinds of believers about whom we know relatively little. I argue that Catholics influenced by Thérèse's teachings, notably the “Little Way” and her “Spirituality of the Ordinary,” modelled the saint's destabilisation of the active/contemplative (or public/private) dichotomy. The letters reveal the entanglement of the spiritual and the secular in the lives of ordinary Catholics and how, after Thérèse, they participated in the Christian animation of society beyond the home. In their writing we also see evidence of the correspondents' attachment to the universal Church when they felt, acutely, the uncertainties of the international situation.     

STORY MAKES HISTORY,THEORY MAKES STORY: DEVELOPING RÜSEN'S HISTORIK IN LOGICAL AND SEMIOTIC DIRECTIONS

This essay will argue that the traditional opposition between narrative and theory in historical sciences is dissolved if we conceive of narratives as theoretical devices for understanding events in time through special concepts that abridge typical sequences of events. I shall stress, in the context of the Historical Knowledge Epistemological Square (HKES) that emerged with the scientization of history, that history is always narrative, story has a theoretical ground of itself, and scientific histories address the need for a conceptual progression in ever‐improved narratives. This will lead to identification of three major theoretical levels in historical stories: naming, plotting (or emplotment), and formalizing. We revisit Jörn Rüsen's theory of history as the best starting point, and explore to what extent it could be developed by (i) taking a deeper look into narratological knowledge, and (ii) reanalyzing logically the conceptual strata in order to bridge the overrated Forschung/Darstellung (research/exposition) divide. The corollary: we should consider (scientific) historical writing as the last step of historical research, not as the next step after research is over. This thesis will drive us to a reconsideration of the German Historik regarding the problem of interpretation and exposition. Far from alienating history from science, narrative links history positively to anthropology and biology. The crossing of our triad name‐plot‐model with Rüsen's four theoretical levels (categories‐types‐concepts‐names) points to the feasibility of expanding Rüsen's Historik in logical and semiotic directions. Story makes history, theory makes story, and historical reason may proceed.     

FROM LEFT‐WING TO COMMUNIST MELANCHOLY: TRAVERSO'S WAGER

Enzo Traverso's inspired book Left‐Wing Melancholia revisits iconic representations of revolutionary hopes and defeats not to draw up an inventory of what has been lost but rather to remind his readers that past defeats also contain the traces of unfulfilled possibilities. After the end of the Soviet Union and the global triumph of neoliberal capitalism, the communist utopian imagination of a classless society, Traverso suggests, can be reignited through memorial practices of resilient, resistant melancholy. Traverso's argument draws on Walter Benjamin's notions of materialist history, redemptive memory, and knowing melancholy. Yet the nameless vanquished masses to whom Benjamin's concept of history seeks to do justice remain marginal in Traverso's book. Instead, revolutionary defeat is cast in the tragic mold of succeeding by failing, a trope exemplified by figures such as Auguste Blanqui, Charles Péguy, or Daniel Bensaïd. In response to Traverso's reliance on the transhistorical category of the tragic, this essay argues for a more abstractly theoretical understanding of left‐wing melancholy as conditioned by historically specific class relations that constrain and challenge the engaged intellectual. Moreover, this essay questions Traverso's dualistic treatment of politically committed (Benjamin, Brecht, C. L. R. James) and elitist intellectuals (Adorno) and concludes that the concept of left‐wing melancholy must ultimately be interrogated against the backdrop of a lingering uncertainty about the relationship between theory and praxis that, as Adorno claims, one can already find in Karl Marx—an uncertainty that is hence inscribed into the history of any Marxist theory of revolution and history.     

Fragments of the Modern City: Material Culture and the Rhythms of Everyday Life in Victorian London

This essay analyses the influence of Charles Baudelaire's and Théophile Gautier's fetishist poetics on the early works of Algernon Charles Swinburne. If the crucial role played by the Victorian poet as a cultural ‘passeur’ between France and England has often been highlighted in recent criticism, his aesthetic delight in certain forms of sexual deviance such as podophilia has rarely been explored in relation to the verse of his French mentors. Swinburne, Gautier, and Baudelaire may have indeed shared this erotic fascination with feet: this is a fascination that was partly grounded in these poets' common interest in antique literary models, in particular in Sappho's poetry. Rather than extolling the Hellenic ‘sweetness and light’ which some of his contemporaries set so high, Swinburne indulged in dangerously eroticised Dionysian aesthetics which were perceived as both ‘too Hellenic’ and ‘too French’. I argue that the fetishism of the poetic foot may be read as one of the keys to the Victorian poet's subversive shift away from the serenity often associated with Victorian neoclassicism in favour of a Dionysian energy that anticipates Friedrich Nietzsche's works.     

One‐dimensional criticism: a Marcusean reflection on Habermas's critical theory1

This paper explores the metaphysical foundations of critical theory in Marcuse and Habermas's postmetaphysical alternative. It argues that Habermas's attempt to free critical theory from a normative conception of life‐activity deprives it of the conceptual tools required to accurately diagnose the fundamental structure of social problems today. It thus concludes that Marcuse's efforts towards specifying a life‐grounded foundation to critical theory must be renewed if the project of human freedom is to be advanced today.     

Continuity and change: prospects for civil—military relations in Turkey

Early indications suggest that the appointment of General Yaþar Büyükanýt as chief of the Turkish general staff (TGS) at the end of August 2006 marked a new era in civil‐military relations in the country. Yet it would be a mistake to see the military's more forthright attitude under Büyükanýt simply as a return to the past. Civil‐military relations in Turkey have always been characterized by a combination of continuity and change. Both the legal basis for and the TGS's own perceptions of the role and responsibilities of the military have remained unchanged for over 70 years. However, the extent and the manner in which the military has influenced politics have always varied. In recent years the TGS's ability to ensure that government policy remains within acceptable parameters has been primarily based on its public prestige rather than the prospect of a full‐blooded military coup. Although the TGS has always been the most respected institution in the country, the Turkish public's willingness to tolerate, or even to encourage, its assumption of a more active political role has traditionally varied according to changes in the prevailing domestic political circumstances: falling during times of stability and confidence and rising during times of uncertainty. In early 2007 both the country and the government of the moderately Islamist Justice and Development Party (JDP) appeared to have lost momentum and direction. In such an environment, and in the continued absence of an eff ective political opposition, many Turks will once again look to the country's military to prevent the JDP from increasing its control over the apparatus of state, starting with the appointment of a new president in April 2007. To date the JDP has always backed down in the face of pressure from the TGS. However, whether it will continue to do so, and what the TGS can or will do if the JDP defies its warnings, currently all remain unclear.     

The Value of Rents: Global Commodity Chains and Small Cocoa Producers in Ecuador

Drawing on the Marxian theory of ground rent, this paper develops an analysis of “global commodity chains” (GCCs) with agrarian roots. There is an acknowledgement that the concentrated downstream governance of primary commodity‐based GCCs has created a set of “asymmetrical” power relations which blocks the transmission of value upstream towards small producers. This paper argues that this research under‐specifies what is meant by value and rent, and in doing so marginalises the analysis of value production before its journey through inter‐firm relations. We demonstrate the importance of theorising the value constitution of commodities produced on the land and the forces that contest the payment of ground rent and thereby shape the geography of GCCs. Based on empirical research conducted around Ecuador's “post‐neoliberal” cocoa re‐activation plan, we identify the class politics and production mechanisms through which value and rent escapes the hands of a stratified network of small owner producers.
