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

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

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

清末地方自治包括府厅州县和城镇乡地方自治两个层级,并建构了两个层级不同的官治与自治模式,即在城镇乡一级实行"以自治辅助官治",而府厅州县则实行"自治与官治合并"之制度。两种模式都借鉴了日本自治制度,但都有所不同。就清末城镇乡地方自治的运行来看,由于地方自治章程赋予官府监督自治之权,也由于自治团体为谋求地方利益,常常也会与官府对立,所以,官治与自治常常处于矛盾冲突之中。  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

我国博物馆应充分运用互联网、多媒体、新媒体等技术手段,使博物馆文化成果惠及更多受众,博物馆微信营销是完成该任务的有效手段之一。我国博物馆通过微信营销策略满足观众需求具有很强的实践性。专业化程度较高、功能较完善、社会作用较明显的96家国家一级博物馆中,有65家开通了微信公众号,但目前微信公众号存在基本内容不完整,功能不完善,内容更新频率低,宣传推广力度不够等问题。今后博物馆应根据自身情况,完善公众号的基本内容与功能,加快内容更新频率来保持目标用户的关注,多途径进行微信公众号的推广,凭借微信公众平台这个低成本的沟通渠道,为观众提供更加优质的服务。  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

In spite of recent advancements regarding regional innovation policy rationales and evidence, there are few analyses about the actual features of existing regional innovation policies. Nevertheless, a policy analysis perspective is important in order to recognize their distinctive patterns across regions, and to understand how rationales and evidence can be translated into policy-making. To this purpose, this paper develops a framework to study the extent to which regional innovation policies have changed during the past few years. Since the mid-2000s, there has been an important development of innovation policy rationales, advocating for more specialization; likewise, greater data availability at the regional level has allowed more sophisticated assessment of innovation performance. Finally, the crisis since 2008 has had ravaging effects in some regions, with job losses and severe economic sluggishness. Therefore, it is reasonable to expect transforming dynamics in regional innovation policies. Against this backdrop, the paper compares the institutional frameworks and budgetary priorities of four Spanish regions during the period 2001–2014: Catalonia, the Basque Country, Galicia and Andalusia. In so doing, it aims at studying the extent to which regional governments have readily addressed past and new challenges related to their regional innovation system, and if so, how.  相似文献
