乡村振兴背景下乡村民宿主创业动机与获得感研究

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。

Discourse on migration and ethnic identity: interviews with professionals in Hong Kong

"This paper has revealed a complex set of relationships between migration, place and ethnic identity [in Hong Kong]. On the one hand, ethnic identity is shaped by the places where people have lived, particularly the places where they have spent the early years of their life; on the other [hand], places--being the context for socialization--provide the milieux where people learn who and what they are and how to act...." The authors note that "while legislation clearly regulates levels of immigration, international migration is also self-regulated by potential migrants in relation to interpretations of their ethnic identities and their perceptions of 'other' places."     

从撰铭到书丹:董其昌《项墨林墓志铭》与《项墨林墓志铭卷》

《项墨林墓志铭》系项元汴次子项德成请董其昌撰写的碑文。项氏家族曾两次请董其昌照原文书丹,第一次为制墓志铭碑,第二次为制神道碑。现存日本东京国立博物馆的《项墨林墓志铭卷》书于明崇祯八年,是项元汴季孙项禹揆为镌刻神道碑请董其昌书丹留下的碑文墨迹。该铭概述项元汴的生平懿行与志业成就,是研究项元汴的基础文献之一,原文收录于《容台文集》卷八,墨迹本在原文基础上有所改动。该书迹是极少数证据充分的董其昌遗存真迹之一,也是体现董其昌取法创变和践行其书法美学思想最具代表性的经典作品。     

国家、媒体及女性作家间的多层“战争”——以吉屋信子和林芙美子为中心

吉屋信子和林芙美子是侵华战争时期日本表现最为活跃的两位女性作家,其曾于1938年作为“笔部队”成员来华,之后分别创作了《波涛》《女人的教室》等作品。通过探究此类作品得以问世的来龙去脉可以发现,日本女性作家的“性别”既是日本军部及媒体有意利用的“标签”,亦是作家本人着意凸显的个体特征。若在此基础上具体分析作品中所建构的“铳后女性”形象,可以透视日本女性作家如何诱导广大日本女性积极协助侵略战争的内在机制,进而追究其应当承担的战争责任。     

Fluid inclusion and isotopic constraints on the origin of ore‐forming fluid of the Jinman–Liancheng vein Cu deposit in the Lanping Basin,western Yunnan,China

Extensive quartz–carbonate–Cu sulfide veins occur in clastic rocks and are spatially related to Paleocene granites in the western border of the Lanping Basin, western Yunnan, China. Abundant aqueous‐carbonic fluid inclusions occur in these veins but their origin is debated. In the Jinman–Liancheng deposit, individual primary inclusion groups contain either exclusively liquid‐rich inclusions (Gl), or coexisting liquid‐rich and vapor‐rich inclusions (Glv). Microthermometry and estimate of CO₂ content indicate that type Gl inclusions either have homogenization temperatures (Th) 238–263°C and contain c. 3.9–5.5 mole % CO₂, or have Th 178–222°C and contain c. 1.6–3.2 mole % CO₂. Type Glv inclusions are thought to represent samples of fluid unmixing that occurred at 183–218°C. At that time, the liquid phase in the unmixing fluid may contain c. 2.0–3.3 mole % CO₂. As such, the correlation of CO₂ content with Th for type Gl inclusions is thought to be caused by fluid unmixing with decreasing temperature and subsequent CO₂ escape. δ¹⁸O and δD values of the parent water mainly fall in the field below that of primary magmatic water, indicative of fluid derivation from degassed (in open system) magmatic water, with no contributions from basinal or meteoric water. Initial Sr isotopic compositions of hydrothermal carbonates suggest that the fluid was magmatic, probably derived from the Paleogene granites. δ¹³C_PDB values (?4‰ to ?7‰) of the hydrothermal carbonates and δ³⁴S_V‐CDT values of sulfides (mainly ?11‰ to +5‰) indicate that the carbon and sulfur can be derived from (degassed) magma and/or nonmagmatic sources. The CO₂‐rich and magmatic‐water‐derived fluid at Jinman–Liancheng differs from the CO₂‐poor and basinally derived fluid in sediment‐hosted stratiform Cu (SSC) deposits, which suggests that there are no genetic linkages between the vein Cu and SSC deposits in the Lanping Basin.     

“自由”话语与冷战初期美国国内政治动员——以欧洲复兴计划为中心

面对第二次世界大战后欧洲的严峻形势,杜鲁门政府酝酿出台欧洲复兴计划。为了动员美国民众支持这一计划,杜鲁门政府构筑了一套以"自由"为核心的政治话语体系。他们从"自由"着眼,制造国家安全威胁,并将苏联视为"他者",与社会团体共同塑造了美国作为"自由捍卫者"的国际形象。借助宣传欧洲复兴计划这一有利时机,美国将强烈的道德因素注入追求国家利益的对外援助政策中。这不仅赢得了美国民众对欧洲复兴计划的认同和支持,而且为美国政府全面介入国际事务提供了"合法性"理由和意识形态上的支持。     

A hairy-bodied tettigarctid (Hemiptera: Cicadoidea) from the latest Middle Jurassic of northeast China

Liu, X.H., Li, Y., Yao, Y.Z. & Ren, D., April 2016. A hairy-bodied tettigarctid (Hemiptera: Cicadoidea) from the latest Middle Jurassic of northeast China. Alcheringa 40, xxx–xxx. ISSN 0311-5518

Extant tettigarctids are also known as hairy cicadas because they are covered by long and abundant hairs. This character had not been reported in fossil species of Tettigarctidae because previous examples were poorly preserved or lacked long hairs. Hirtaprosbole erromera gen. et sp. nov. (Tettigarctidae) with a hairy body, from the latest Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China, is described here. This new species provides evidence that tettigarctids with long dense hairs had appeared by the latest Middle Jurassic and lived at high altitudes.
