Archaeologists can learn from models of evolution as a self-organized critical phenomenon. Self-organized critical systems are large, interactive systems that organize into a critical state where minor events can trigger chain reactions. Such systems demonstrate power-law distributions in the size of changes, or avalanches, that occur. The theory of self-organized criticality is important in that it implies that the evolution of complex systems may be driven more by interactions between agents than by external events or natural selection. Stylistic changes may be examples of avalanches of interconnected events. Evidence for self-organized criticality is shown for stylistic evolution in historical pottery styles from New York State and is used to evaluate the nature of a prehistoric pottery typology from the Southwest.  相似文献

The average citizen often does not experience government policy directly, but learns about it from the mass media. The nature of media coverage of public policy is thus of real importance, for both public opinion and policy itself. It nevertheless is the case that scholars of public policy and political communication have invested rather little time in developing methods to track public policy coverage in media content. The lack of attention is all the more striking in an era in which media coverage is readily available in digital form. This paper offers a proposal for tracking coverage of the actual direction of policy change in mass media. It begins with some methodological considerations, and then draws on an expository case—defense spending in the United States—to assess the effectiveness of our automated content‐analytic methods. Results speak to the quantity and quality in media coverage of policy issues, and the potential role of mass media—to both inform and mislead—in modern representative democracy.  相似文献

The differences between China and Western countries in human and physical environment has brought about two distinctive models of state. In the Chinese-style state of quasi-consanguinity, in which family and state have a similar structure, imperial power, gentry power, and clan power are the product of common ownership of consanguineous groups. The similarity in the structures of these three kinds of power derives from the fact that they are all restricted by the power of lineage generated from the self-sufficient small farmer economy, and must obey the conventions of ancestors which hold the benefits of the group as supreme. The relationship between these three kinds of power, is definitely not the one that is based on the division of power that is founded on individual private ownership in Western countries, where ‘public power’ and ‘individual private ownership’ are antithetic, but are three aspects of the patriarchal dictatorship that complement each other. Therefore, village rule in China and autonomy in the West are two totally different concepts, and gentry power is also not the ‘authorized power’ from the state. __________ Translated from the Journal of Tianjin Normal University, 2004: 1  相似文献

以表现方式和取材方法为主,结合现代学者对古代地理文献类型的划分以及明代的具体实情,可以将明代的地理文献划分为传统地志类、广义游记类、西传地理文献类和舆图类。它们在明代均得到了较快的发展。虽然都是地理文献,但它们之间又存在着诸多差异。通过对这些文献的分析研究,我们可以窥见明代地理学的发展趋向。  相似文献

论广告的起源问题   总被引:1,自引:0,他引:1  
杨海军 《史学月刊》2000,(4):43-47,55
传统观点认为,广告是伴随着商品生产和商品交换而出现的,是商品经济发展的必然产物。这种观点所揭示的只是“商品广告”的起源问题。从广告的发展、演变历史及人们对广告的理解来看,无论是原始意义,还是现代意义上的广告,均并非单指“商品广告”。它还应包括政治、军事、文化广告,统称为“社会广告”。其产生的时间早于“商品广告”。本文的主要观点是:广告是人类有目的信息交流和传播活动的产物。  相似文献

Ethnoarchaeology appears nowadays as a poorly formulated field. However, it could become a real science of reference for interpreting the past if it was focused upon well-founded cross-cultural correlates, linking material culture with static and dynamic phenomena. For this purpose, such correlates have to be studied in terms of explanatory mechanisms. Cross-cultural correlates correspond to those regularities where explanatory mechanisms invoke universals. These universals can be studied by reference to the theories found in the different disciplines they relate to and which are situated outside of the domain of archaeology. In the domain of technology, cross-cultural correlates cover a wide range of static and dynamic phenomena. They allow the archaeologist to interpret archaeological facts—for which there is not necessarily analogue—in terms of local historical scenario as well as cultural evolution. In this respect, it is shown that ethnoarchaeology, when following appropriate methodologies and focussing on the universals that underlie the diversity of archaeological facts, does provide the reference data needed to climb up in the pyramid of inferences that make up our interpretative constructs.  相似文献

The standard theory of optimal jurisdictional size hinges on the existence of economies of scale in the provision of local public goods and services. However, despite its relevance for forced local amalgamation programs and related policies, the empirical evidence on the existence of such economies of scale remains elusive. The main goal of this paper is to produce an updated and comprehensive quantitative review of the existence of economies of scale in the provision of local public goods using a meta-analysis approach to systematize the wide range of empirical approaches and modeling frameworks found in the previous literature. Our analysis confirms the presence of moderately increasing to constant returns to scale in the provision of local services with no reduction in the average costs of production in the delivery of most local public services beyond a certain, modest jurisdictional size, which many studies have estimated at 10,000 residents. Also, the potential for economies of scale differs at least across three traditional services: education, water and sanitation, and garbage collection, being highest for education and lowest for garbage collection. Our analysis also offers guidelines for future empirical research in this area. Physical output and production cost data should be used, together with translog specifications for the modeling of cost functions. Last, we find evidence that the determinants of output cost elasticity include bidirectional publication bias and population density but do not include the presence or absence of modern “lean” production technologies or the (perceived) capital intensity of the sector, contrary to conventional wisdom. These findings have significant policy implications for countries considering jurisdictional consolidation programs.  相似文献

Abstract

With the processes of modernization, urbanization and the entry of women in the formal labour market in Indian metropolitan spaces, this article examines how the modern middle-class woman’s sartorial choices become enmeshed in popular rape myths (false beliefs) that serve to blame her for the wearing of western clothing. The article articulates the ways in which middle-class women’s social realities are shaped by historical, colonial and nationalist ideologies of modernization, constructed and mediated through moral codes of dressing. By drawing upon original and contemporary empirical narratives from the urban spaces of Delhi and Mumbai, we emphasise how everyday sartorial choices, in relation to particularly the bra and lingerie, can reveal the nuanced ways in which Urban Indian Professional Women (UIPW) seek to understand, negotiate, and resist patriarchal power. Our findings shed light on conflicting and contradictory spatial experiences, where some women internalize and negotiate moral codes of dressing, out of fear, and others who transgress are subject to sanctions. Given the paucity of scholarly literature in this area, the article makes an important theoretical and empirical contribution with its focus on postcoloniality and everyday discursive material spaces of gendered and sexualized dress practices. It argues for the consciousness raising of everyday urban geographies of dress that reveal complicated structures of power that are often deemed hidden.  相似文献
