Knowledge about the Inca measurement system is based on information from the colonial chronicles and modern studies of the 16th-century Quechua dictionaries. Based on those texts, we can presume that the Incas used an anthropometric system of measurement adopted from the proportions of the human body. Using cosine quantogram analysis and statistical verification, it is possible to verify the existence of the measurement system used by the Inca architects. For this purpose, a measurement series of architectural and water infrastructure elements were collected from 3D point cloud of the Chachabamba and Machu Picchu settlements in Machupicchu National Archaeological Park. 相似文献

While food allergy prevalence has been studied at the national level, we know little of food allergy prevalence or perceptions of prevalence/management at the local level. This paper uses Waterloo Region as a case study to 1) document self-reported individual and household food allergy and sensitivity prevalence at the local level; 2) investigate perceptions of food allergy prevalence; and 3) explore perceived confidence in anaphylaxis management. Survey data were collected from January to March 2019. Respondents (n = 500) self-reported individual and household food allergy and sensitivity, estimated the percentage of Canadians with food allergy, and were queried about their knowledge of food allergy management. Prevalence estimates were weighted to the structure of the 2016 Canadian Census, and univariate and bivariate analysis were conducted. Prevalence of self-reported food allergy was 12.1% (95%CI, 8.8%-15.3%), and prevalence of self-reported food sensitivity was 26.3% (95%CI, 21.9%-30.7%). When asked to estimate the percentage of Canadians with food allergy, the mean perceived percentage was 35.1% (SD = 22.96). Self-reported prevalence of food allergy appears higher in Waterloo Region, and the estimated percentage of Canadians with food allergy is inflated. Understanding prevalence and perceptions at the local level is important for targeted allocation of public health resources to ensure safe spaces for individuals with food allergy. 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

In this work, we apply a systemic approach to the analysis of a particular geographic territory, the industrial district. We are particularly interested in analysing the interaction between the productive-technological environment and the scientific environment by an examination of research contracts and patents. Our analysis shows that R&D activity in the Spanish ceramic tile District Innovation System was mainly conducted by suppliers. Final producers’ innovation efforts were related to non-technological aspects and differentiation. 相似文献

New industrial innovation policies like smart specialization aim at boosting economic growth by diversification towards more complex and higher value economic activities. This paper proposes a conceptual and analytical framework to support the design and implementation of such policies considering place-specific preconditions, particularly the differentiation of the regional system of innovation and entrepreneurship and the degree of current industrial diversification. The paper expands on the links between these preconditions and the barriers and opportunities for industrial diversification. Consequently, it proposes an archetypical place-based policy framework covering overall policy objectives as well as measures at the level of actors, networks, and the institutional and organizational support structures. 相似文献

There is little research on children’s experiences of growing up in a popular tourist destination, where place and space are contested with visitors, migrants and temporary residents. Existing literature on young people’s experiences of their socio-spatial surroundings has focused predominantly on the rural/urban dichotomy, often neglecting to explore how identity and belonging are negotiated in complex community contexts such as tourist destinations. This paper reports on recent research that suggests that young people’s experiences of growing up in such an environment are nuanced and diverse, with their rich narratives disrupting socially constructed distinctions between the rural and the urban, merging experiences from both worlds. 相似文献

This article argues that warfare has been marginalised in theories of nationalism but that in conjunction with nationalism is vital for understanding the rise of nation‐states, the formation of nations and the nature of the international system. It offers a critique of statist approaches, suggests mechanisms through which warfare may sacralise nations and explores different patterns of nation‐state formation as they affect the interstate system. In particular, it emphasises tensions between state and nation‐formation as activated by the fortunes of war and the destabilising effects of waves of imperial dissolution, which are accompanied by patterns of re‐imperialization. It suggests that it is simplistic both to claim that war has led to a transition from empires to nation‐states and that contemporary practices of war‐making have led to a postnational era. 相似文献

The criminal justice system is increasingly becoming the subject of national dialogue throughout the United States due to the sheer number of people it impacts: according to the Department of Justice, nearly 7 million, or 1 in 35, U.S. residents are under some form of correctional control. The four books reviewed in this essay derive their findings from ethnographic methods that offer deep insights into the carceral state’s everyday operations in individual women’s lives, while raising profound theoretical and practical questions about gender and governance. We engage with these texts from unique situated standpoints as insider-outsiders with intimate knowledge of the U.S. criminal justice system gleaned from our respective lived experiences, services provision work, and research with currently and formerly incarcerated Wyoming women. 相似文献

文化遗产基金制度或与文物保护相关的艺术基金制度在西方发达国家已基本完善。基金会通过多渠道广泛地筹集资金,并有效地进行战略管理和再投资;同时,基金会的日常运作公正透明,具有完善的内外部监督机制。这些贯穿于基金运作各层面的制度及运作经验十分值得我国借鉴。 相似文献
