"Malthusians maintain that rapid population growth aggravates poverty, while Marxists contend that social formations determine its nature and extent. Each perspective is incomplete, however, since it ignores the insights of the other. Latin American states, characterized by dependent capitalism formations and dominated by ruling elites, are generally incapable of solving the problems of population and poverty. Since population growth under dependent capitalism weakens labor's bargaining position against capital, reduced population growth is emphasized as a labor empowerment strategy the poor can implement on their own to improve their socioeconomic conditions." 相似文献

Archaeometric analysis of ceramic production in Tiwanaku state (c.500–1000 ce): An exploratory study
J. P. Ogalde A. Korpisaari C. Riera‐Soto B. Arriaza C. Paipa P. Leyton M. Campos‐Vallette N. Lara J. Chacama 《Archaeometry》2021,63(1):53-67
The chemical and mineralogical characterization of seven ceramic fragments produced within Tiwanaku state (c.500–1000 ce ) is reported. The instrumental techniques used included X‐ray elemental and mineralogical chemical analysis, Raman spectroscopy, and scanning and light microscopy. The results indicate there are several clay types, although they show similarities, such as the use of a plant‐based temper. The red colour of the decoration is hematite, and manganese oxides such as jacobsite are present in the black. The white colour is a mixture of gypsum and clay, and the orange is a mixture of hematite and clay. The use of colours, the quality of the clays and the temperatures reached during pottery firing point to expertise in ceramic production and to complex decision‐making processes. The multi‐elemental archaeometric approach documented here could become an important tool to shed a light on ancient ceramic technology and the internal variance of Tiwanaku pottery. 相似文献

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce . 相似文献

14年抗战,九一八事变是毫无疑义的起点。在这历史的起点,中共是当事各方都没有忽视的重要存在。实际上,当时日本利用一切机会强调中国共产党这一因素在东北问题复杂性中的地位。当国际联盟(League of Nations)派员到东北实地考察时,日方以当地“土匪”有受共产党“策动之虞”,配置装甲车,作为国联专列的“先导”,①以作微妙的提醒。 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

Studies of dog remains focused on the Iron Age southern Levant generally highlight their unique nature in the archaeological context, specifically in relation to their post-mortem exploitation. Here we review the published archaeological and textual data to evaluate the current understanding of dogs’ roles in their Iron Age settings. The analysis reveals that dogs are relatively common in the archaeological record, having been reported at 66% of sites. This study further contextualizes this presence in light of their co-occurrence with caprine and wild taxa. The significant number of dog remains indicates that they were part of the social matrix of a village. While dogs have been viewed as ‘unclean’ or pariah, based on certain textual references in the Hebrew Bible, we assert, on the basis of the archaeological record, that they were part of the life of the village, functioning as herders, guards and occasionally hunters. 相似文献

The issue of fairness often is central within environmental policy debates. The recent proliferation of state and local comparative risk projects for informing the selection of environmental policy priorities offers an appropriate setting to explore the issue of procedural fairness in risk-based decisionmaking. This paper describes and evaluates the process by which one of the initial state comparative risk projects, Washington's “Environment 2010,” attempted to include a broader range of participants in identifying, assessing, and generating preferred management strategies for a wide range of environmental hazards. The Washington case study suggests that comparative risk projects can be fairer procedurally, but that significant barriers remain. Noting that greater procedural fairness does not necessarily produce greater substantive fairness, the paper concludes that more attention needs to be directed at the process by which comparative risk projects translate their consensus upon risk priorities into subsequent actions. 相似文献
