我国农业结构战略性调整的目标与态势分析

农业结构调整是针对当前我国农业面临的突出问题和面向中长期农业发展目标而实施的农业振兴计划,其根本目标就是把长期以来不符合市场消费需求和没有市场前景的品种及播种面积果断地退下来,形成适应农业发展多样化、优质化、专用化的市场需求,促进农业经营逐步由粗放型向集约型、由数量型向质量效益型的根本性转变。积极推进农业结构调整也是加入WTO后实现我国农业可持续发展的基本出路和动力。近几年来,受国家宏观调控与市场调节作用的影响,我国农业结构调整战略性调整快速推进,农业生产的优势区、产业带新格局正在形成。     

A DIALECTICAL APPROACH TO RESEARCH AND DEVELOPMENT PLANNING

This paper reports on the methodology and an application of a dialectical approach to research and development, planning. The methodology features a structured debate followed by argumentation analysis. The argumentation analysis in turn is followed by an assessment of the plausibility of the arguments. The application involved using the methodology to assess the level of funding for research and development for a transportation system that would employ advanced technology. The Dialectic Inquiry process, and specifically, the plausibility rating activity, were seen as valuable aids for policy analysis.     

RESEARCH,NARRATIVE, AND REPRESENTATION: A POSTNARRATIVE APPROACH

Narrativism or representationalism is founded on the idea that historical narratives and representations are 1) true and indivisible wholes, whereof 2) the truth needs to be maintained, although a narrativist or representationalist whole cannot be confirmed or disconfirmed, and wherein 3) the past is represented in a figurative sense. These fundamental aspects of narrativism have had a positive impact on historiography, but they are also the three reasons why narrativism has neglected historical research and argumentation. To remedy these problems postnarrativism has been evoked. It opts for presentation instead of representation, cutting through all the links between the past and the historiographical product. The product is not a narrative or a representation but a thesis, a proposal to see the past in a special way. The only element postnarrativism wants to retain of narrativism is colligation because it has an argumentative structure based on epistemic values. Postnarrativism leads to knowledge, built on the practice of warranted assertions instead of truth. My postnarrativism chooses a middle course between a strong narrativism and what I would like to call a “weak,” presentational postnarrativism. I agree with postnarrativists that more attention must be paid to argumentation and research. Moreover, I consider time a neglected issue in narrativism. Nevertheless, I don't want to give up the three above‐mentioned fundamental aspects of it. In my view the assumption of truth with regard to (figurative) representation needs to be maintained, but in a pragmatic, provisional form: a historical narrative or representation can be considered as true as long as it has not been replaced by a better one. Retaining truth and holism, but wanting more room for investigation and argumentation, requires that narrativism's role in historical research and history‐writing be revised. This implies the replacement of the usual research phase by a preparation phase, wherein, next to research, space must be reserved for so‐called writing activities. Preparation means the conversion of a germinal narrative or representation into an accomplished whole. Holism occurs in two representational forms: a narrative and a representation. In both forms, research concepts and the associated temporalities become visible under the surface of the narrativist or representational superstructure.     

TRUTH AND MEANING IN HISTORICAL INTERPRETATION: A DAVIDSONIAN APPROACH

This essay argues that Donald Davidson's work in philosophy sheds light on debates about truth, meaning, and context in historical interpretation. Drawing on distinctions between Davidson's project and that of his mentor, W. V. O. Quine, I aim to show that certain ambiguities that have arisen in the methodological reflections of Quentin Skinner and Frank Ankersmit, to take representatives of contrastive approaches to intellectual history, are clarified once we reckon with Davidson's ideas. This discussion leads to a case for the broader pertinence of Davidson's work to historical writing, which insists that his focus on the centrality of truth to disagreement bears salutary consequences for thinking about what constitutes compelling historical scholarship.

RELIABILITY AND APPLICABILITY OF NAKAMURA'S TECHNIQUE USING MICROTREMORS: AN EXPERIMENTAL APPROACH

Nakamura's technique has been widely discussed from the theoretical point of view. Very little information is available as far as the experimental, on-the-field standpoint is concerned. A series of experiments under controlled conditions were set up to assess the reliability and applicability range of this microtremor technique. Since this approach to microzonation is particularly appealing in urban environments, great care was devoted to evaluate the influence of factors such as anthropic noise, concrete or asphalt coverings and soil-structure interaction. Environmental factors (wind) and the influence of sensors were also considered. The results were compared with the seismic response from four earthquakes. The set of experiments shows that under proper measurement conditions Nakamura's technique provides stable and reliable results, but great care has to be devoted to avoid factors that may significantly and adversely affect the results.     

AN INDUSTRIAL AGGLOMERATION APPROACH TO CENTRAL PLACE AND CITY SIZE REGULARITIES*

ABSTRACT An empirical regularity designated as the Number‐Average Size (NAS) Rule was first identified for the case of Japan by Mori, Nishikimi, and Smith , and subsequently extended to the United States by Hsu . This rule asserts a negative log‐linear relation between the number and average population size of cities where a given industry is present. In this paper, we utilize the cluster‐identification methodology developed by Mori and Smith to sharpen this notion of “industrial presence” by focusing only on cities that constitute at least part of a significant spatial agglomeration for the given industry. Our key result is to show that the NAS rule continues to hold (even more strongly) under this sharper definition.     

RESEARCH IN HUMAN ECOLOGY AND PLANNING: AN INTERACTIVE, ADAPTIVE APPROACH

The aim is to describe an approach to research in human ecology and planning, primarily for the consideration of younger scholars. The approach is termed interactive and adaptive and is viewed as being especially useful in research on environmental, resource, land use or other topics in turbulent environments, characterized, for example, by an array of interested or concerned groups, differences in values, and frequent changes in the research context. The approach is illustrated by reference to several case studies in applied human ecology and planning in Canada.
Le but de cet article est de décrire une approche pour la recherche en écologie humaine et en planification qui bénéficie principalement aux jeunes chercheurs et chercheuses. L'approche est intéractive et adaptable. Elle est spécialement utile en recherche sur l'environnement, les ressources naturelles, l'utilisation des terres ou autres domaines touches par des environnernents troubles. Ceux-ci peuvent être caractérisés, par exemple, par une variété de groupes concernés ou intéressés, par des différences de valeurs et par des changernents fréquents du contexte de la recherche. L'approche est présentée en faisant référence à plusieurs études de cas en écologie humaine appliquée et en planification au Canada.     

4. THE GADAMERIAN APPROACH TO THE RELATION BETWEEN EXPERIENCE AND LANGUAGE

Narrativism as a theory of historical depiction intuitively opens the question: what is left of reality when it is poured through the filter of language structures? And, extended a little bit further, questions arise: What is responsible for the final shape of a historical depiction? Is it experience or language? What is affecting what? Narrativism typically accuses language units of transforming experience in a specific way. However, even in asking these questions, the problem of the separation of experience from language and language from experience remains. In this article, I address this issue using Gadamer's hermeneutical frame. Wherever philosophical tradition insists on the separation of certain positions, Gadamer tries to show their ontological connections. For Gadamer, understanding is a basic ontological structure, within which both sides of a dialogue affect and constitute each other. In Gadamerian hermeneutical ontology, there is no “starting point” or first responsible position. In the understanding, dialogue has the permanently moving character of a play, where separate positions are erased. This Gadamerian view can also be applied to the question of language and experience and their mutual connection in depicting any experience via language. In Gadamer's example of the work of art, the original subject matter (Urbild) is articulated through its depiction. The subject matter dictates possible ways of depicting, which in turn dictate the final shape of depiction. In this article, I discuss Gadamer's term “articulation of the world,” by which he means a function of language. Articulation is simply a transformation of shapeless matter into a shape, and in our case it is a transformation of an experience into a language depiction. I show that the Gadamerian approach to language and experience can offer an interesting perspective on the issues discussed in reaction to narrativist philosophy of history.

RISK AND INCOME TRADEOFFS IN REGIONAL POLICY: A PORTFOLIO THEORETIC APPROACH*

ABSTRACT. Policy makers often try to raise a region's income by altering its industrial mix. However, such attempts to increase local income may have an adverse effect on the stability of the region's economy. In this paper, we develop single-, aggregate-, and multiregional portfolio models that can be used by policy makers to generate frontiers of risk/income-efficient industrial mixtures for a regional economy. These portfolio models are modified for application to the tourist industry in six regions of Spain. In practice, we find that the introduction of bounds on the magnitude of sector rebalancing has a major effect on the model solutions.     

REVISITING PLATFORM MOUNDS AND TOWNHOUSES IN THE CHEROKEE HEARTLAND: A COLLABORATIVE APPROACH

Abstract

This article describes the development and initial results of the Western North Carolina Mounds and Towns Project, a collaborative endeavor initiated by the Tribal Historic Preservation Office of the Eastern Band of Cherokee and the Coweeta Long Term Ecological Research Program at the University of Georgia. The goal of this project is to generate new information about the distribution of late prehistoric mounds and historic period townhouses in western North Carolina. This ongoing research has produced updated location and chronological data for 15 Mississippian period mounds and historic Cherokee townhouses, and led to the discovery of a possible location for the Jasper Allen mound. Using these new data, I suggest that David Hally's model for the territorial size of Mississippian polities provides a useful framework for generating new research questions about social and political change in western North Carolina. I also posit that the cultural practice of rebuilding townhouses in place and on top of Mississippian period platform mounds, a process that Christopher Rodning describes as “emplacement,” was common across western North Carolina. In terms of broader impacts, this project contributes positively to the development of indigenous archaeology in the Cherokee heartland.     

ARCHAEOLOGICAL AND CHEMICAL RESEARCH ON SEDIMENTS AND CERAMICS AT POLIDEPORTIVO (SPAIN): AN INTEGRATED APPROACH*

This paper proposes a preliminary approach to the integration of archaeological evidence and various chemical analyses (phosphorus and lipid) on sediments and ceramics. Phosphorus and organic matter analyses are, thus, used for the study of sediments, and lipid analyses for pottery from structure 19 of the Late Neolithic—Early Copper site known as ‘Polideportivo’, Martos, southern Spain. The results of both types of analysis point to a predominantly domestic function for this structure.
