民宿是落实乡村振兴战略的重要实践,研究民宿主的创业动机和获得感对推进乡村产业振兴具有重要的理论和实践意义。本文通过25位民宿主深度访谈发现,创业动机存在双生机理,且与马斯洛需求层次理论相吻合,呈现出层次性,在经济、情感归属等内部动机之外,创业政策等外部动机驱动民宿创业。创业获得感呈现出多维度性,且受创业动机驱动呈现出相应的层次性。创业动机层次越高,精神层次的获得感就越强,其对应采取的经营模式就不同。获得感意味着资本的积累,进一步驱动民宿主采取行动满足更高层次的需求。基于此,本文构建了创业动机、获得感和经营模式之间的理论框架,探索了乡村振兴的创业环境下民宿主的特征、创业过程和创业结果之间的关系。  相似文献

西藏寺庙内的壁画表面普遍存在被烟熏污染物覆盖的现象。为了解烟熏污染物的成分和来源,以便为文物保护作参考,本研究以西藏桑耶寺壁画表面烟熏污染物为研究对象,对烟熏污染物样品进行扫描电子显微镜分析(SEM)、红外光谱分析(IR)和剖面分析。结果表明,壁画表面烟熏污染物的厚度约为80μm,其主要成分为饱和脂肪酸甘油酯或饱和脂肪酸与大量的碳颗粒形成的混合物,环境检测结果表明酥油灯燃烧导致室内环境中的挥发性有机气体及颗粒物严重超标。研究成果可为以后的文物保护提供参考。  相似文献

In this paper, we explore the heuristic potential of a set of ideas about the structural and functional complexity of systems, proposed in the 1990s by theoretical biologist Daniel McShea. In particular, we focus on the structural aspects of the complexity exhibited by social systems organized into low- and intermediate-level functional units (i.e., groups and teams). To address this subject, we describe a methodology suited for measuring the complexity in the organization of work in such systems, which is primarily based on hierarchical task analysis. With this methodology, we approach a concrete case study: the construction of megalithic monuments in late prehistoric Iberia (ca. 3800–1800 BC). On the basis of the analysis of the three best documented, most structurally, and functionally complex monuments built within each of the three periods under study (Late Neolithic, Copper Age, and Early Bronze Age), we found that there was a trend towards less complexity in work organization related to monument building from the Late Neolithic to the Early Bronze Age. We discuss the importance of these results in light of the existing models of social complexity in European Later Prehistory, concluding that a more balanced view of social processes would be obtained if we look at complexity as a property of every different social system integrated into the whole society, and not as an exclusive property of the latter.

Recent excavations at the Postclassic period (circa a.d. 1000–1521) mortuary mound of El Cementerio (SON P:10:8), located along the Río Yaqui in central Sonora, Mexico, have documented 105 mortuary features (111 individuals) many of which display elongated intentional cranial modification and several cases of tooth filing. These constitute biocultural traits common across much of Mesoamerica throughout its Prehispanic cultural sequence, which expanded along West Mexico and into northwest Mexico beginning in the late Classic period. The examples from El Cementerio represent the northernmost concentrated expression of these traits and could represent the spread of Mesoamerican/West Mexican identity associated with macro-regional trade and the expansion of the Aztatlán archaeological tradition during the Postclassic period in the region.  相似文献

Sagasti, A.J., García Massini, J., Escapa, I.H., Guido, D.M. & Channing, A., August 2016. Millerocaulis zamunerae sp. nov. (Osmundaceae) from Jurassic geothermally influenced wetland environments of Patagonia, Argentina. Alcheringa 40, xxx–xxx. ISSN 0311-5518

A new species of Millerocaulis Erasmus ex. Tidwell emend. Vera is defined based on several permineralized stems recovered from geothermally influenced chert deposits in the Middle–Late Jurassic La Matilde Formation (Santa Cruz, Argentina). Millerocaulis zamunerae sp. nov. is characterized by the presence of an ectophloic dictyoxylic siphonostele, inner parenchymatic and outer sclerotic cortices, homogeneous sclerotic ring in the petiole bases, two masses of sclerenchyma lining the concavity of the petiolar vascular bundle, petiolar inner cortex with sclerenchyma strands in the outermost petiole cycles and stipular wings having one large and several smaller sclerenchyma bundles. Millerocaulis zamunerae inhabited geothermal wetlands and other hot-spring-related sedimentary facies associated with the La Bajada epithermal deposit. Reference to active geothermal wetlands, analogous living plants and other fossil hot spring ecosystems suggest the plant’s tolerance of physico-chemical stressors including elevated temperature, pH, salinity and phytotoxic metals/metalloids. Millerocaulis zamunerae thrived in wetlands preserved in the Jurassic geothermal systems of Santa Cruz Province, the same kind of environment in which Equisetum thermale Channing et al. was recorded previously.

This article deals with the myriad determinants involved in pottery distribution in northeast Ghana, considered from a theoretical perspective that integrates the materiality of vessels and the social, political and historical context where both communities and pottery operate in their daily practice. Hence, we develop a comprehensive research strategy that combines emic and etic views covering the multiple dimensions of pottery life history. In this sense, production units, technical traditions and the characteristics of the redistributive centres, as well as the strategies for pottery acquisition, are studied. Special attention is paid to quite varied aspects such as the physical properties of vessels and their performance characteristics, the reputation of both vessels and potters according to the consumers and the mobility and connectivity patterns found in the study area. On the other hand, interpretations regarding the historical and sociopolitical context of the region are emphasised, as well as the interethnic relationships amongst groups inhabiting the area.  相似文献

救亡图存语境下,近代报刊公共空间的建构与其时社会、政治语境有密切关系.《申报·自由谈》是近代中国著名的报纸副刊.1932年留法归国的青年黎烈文主编《自由谈》,期间所进行的改革引人注目,构建起中国近代报刊史上为数不多的公共舆论空间.20世纪30年代,中国面临着对外抗击日军侵略、对内停止内战这一时代主题,《自由谈》的改版恰与时代主题相勾连,使其报刊公共空间的建构成为可能.《自由谈》编辑"兼容并包"的编辑思路集结了当时国内重要的作家,形成多元化的作家群体,而作家群体私人性的杂文写作则成为《自由谈》公共领域的独特话语表述方式.然而,缺乏广泛社会基础的《自由谈》公共空间在国民政府的强力压迫之下难逃"再封建化"的宿命.  相似文献
