This article analyses the candidacy of King John III Vasa in the royal elections of Poland-Lithuania in 1573 and 1575. Although the ‘Polish-minded’ policy of John Vasa is commonly known in earlier historiography, Swedish and Finnish historians have not given much attention to John III’s election campaigns in Poland-Lithuania in the 1570s. This article contemplates John III’s candidacy and rejection from the perspective of Poland-Lithuania. The royal elections are analysed as a political decision-making process by the Polish-Lithuanian estates. Thus the article emphasizes the existence of past alternatives and conditions of decision-making in early-modern history.  相似文献

构造了一个由数量老龄化、结构老龄化和密度老龄化三个指标所组成的综合老龄化指数(CAI),并建立了一套人口老龄化空间类型划分方案,运用多尺度空间自相关分析对长春市人口老龄化空间的时空演变及空间类型进行研究。结果表明:①长春市近10年出现了老年人口郊区化的趋势,人口老龄化空间的“中心-边缘”分布格局在10年内没有发生显著改变,但空间扩散趋势十分明显,东部和南部近郊区出现了明显的人口老化趋势。②长春市形成了残留老化、集聚老化、自然老化和集聚稀释四种不同的人口老龄化类型区。城市核心区和远郊区形成以非老年人口大量流失为基本特征的残留老化型地区,而近郊区则形成以年轻人口大量涌入为特征的集聚稀释型地区,人口老龄化空间整体上呈现出一种城市中心区和远郊区的老化程度高于近郊区的夹层结构。  相似文献

为探讨壳聚糖/二氧化硅复合仿生膜对碳酸盐石材的保护作用,采用仿生合成技术,以十六烷基三甲基溴化铵为有机模板,能过壳聚糖调控二氧化硅颗粒的生长,在碳酸盐石材表面仿生合成得到了一层壳聚糖/二氧化硅复合保护膜,对其基本性能进行了检测评价,并利用衰减全反射红外光谱和场发射环境扫描电子显微镜表征了膜的结构形貌。实验结果表明,该膜具有优良的耐酸、耐污性能,提高了膜层的抗冻融性和耐热老化性能,并保留了石材原有的吸水性和透气性。壳聚糖/二氧化硅复合膜改善了单一二氧化硅膜的开裂问题,且该保护膜与石材基体结合紧密、膜层薄,小影响石材外脱,是一种良好的碳酸盐石材保护材料。  相似文献

In the thirteenth and fourteenth centuries, Castilian kings were constantly in motion, travelling through their kingdom, an activity which has traditionally been linked with the absence of a single capital in Castile. This paper re-examines the role played by royal itineration in this period and the reasons which inhibited the consolidation of an undisputed capital in the kingdom. In doing so, the changing importance and functions of the main cities of the realm, Toledo, Seville, Burgos and Valladolid – the spaces of royal power – will also be discussed. The main factor which precluded the rise of a single capital was the kingdom's specific territorial configuration, not bureaucratic under-development. The Reconquista led to the creation of a ‘composite kingdom’, in which kingship was exercised differently in some regions compared to others.  相似文献

Chronic non‐communicable diseases comprise a major challenge for health in contemporary Australia and across the globe and, while various factors are at play, personal choices in behaviour and lifestyle are significant. The physical make‐up and ongoing management of the places where we live positively and negatively influences these lifestyle choices and subsequent health outcomes. However, responses—in research, policy, built environment design, construction, and management—frequently fail to recognise the intricacies of this people‐place‐behaviour nexus largely because those responses are highly focused and empirical. Rather, the health‐supportive environments needed to address the current chronic disease epidemic also require additional—networked, nuanced, and intuitive—understandings. Responding to that need, the study described in this paper took a comprehensive view of what constitutes a health‐supportive built environment. We detail the composite methods employed—built environment audits, interviews, and focus groups—all of which are available for use by others in similar situations. Then, using two case study examples, we reflect upon how our methodology revealed otherwise hidden aspects of the extent to which the study sites supported or hindered health‐supportive behaviours and responses. These results suggest intervention actions for policy makers and practitioners that will help them respond to the complex needs of communities in creating a health‐supportive environment.  相似文献

This article discusses seven bone fragments excavated during the second Belgian archaeological campaign at ed-Dur (tomb G.3831, area N). Rather than weaving implements, these objects are identified as the reinforcing bone laths of composite bows. Information on the composite bow in general—origins, structural composition and technical advantages—will be given. Additionally, the question of which types of composite bows could have been present at ed-Dur and what role these weapons could have played at the site are discussed.  相似文献

Two composite anchors of a kind not hitherto identified, each composed of a re-used ashlar block, a wooden shank, two arms and a rope, were discovered recently on the Dead Sea shoreline. Two additional anchor weights of identical type were found in the same region. The two well-preserved anchors were dated to the Fatimid-Crusader period. The shank and the arms were made from local tree species: Christ thorn and tamarisk, and both ropes of date-palm.

In this study we present evidence supporting the view that people's perceived risk of hurricane‐related hazards can be reduced to a single seriousness score that spans different hurricane‐induced risk types and that compliant behavior with official advisories is strongly dependent on whether one perceives a high risk with respect to any type of hurricane‐related hazards. Our analysis suggests that people are less sensitive to risk type than they are to the general seriousness of the risks. Using this single seriousness score, representing a composite risk measure, emergency managers can be informed about the severity of the public's risk perceptions to impending hurricane hazards and might better craft their public directives in ways that minimize disruptive evacuations and achieve greater compliance with government directives.  相似文献

故宫博物院古建筑防雷保护工作的回顾   总被引:2,自引:0,他引:2  
北京故宫在建成之时,就有雷害伴随,不断出现雷击起火,损毁建筑物的事故。本文回顾了故宫博物院上世纪50年代以来古建筑防雷工作的情况,特别是1984年国家颁布试行《建筑防雷设计规范》后,对故宫古建筑之材料进行相关的数据调查和实验,作为防雷设计的依据。同时对防雷问题较严重的几座殿宇的防雷装置的改进,大大提高了防雷保护能力。此外,作者还对故宫落雷的条件和一些雷击事故加以科学分析。  相似文献
