花卉与花卉语

花卉世界,品种繁多。由于文化的差异,不同的国家和民族对花卉的喜爱和厌恶就存在差异,形成了具有不同象征意义的花卉语和各具特色的花卉语文化。本文分析了不同民族对花卉不同态度的一些原因和花卉语的象征意义,介绍了花卉在人们日常生活中的几种独特作用和在英语等文学语言中的应用,反映了不同民族不同文化的内涵。     

论雪漠“大漠小说”的异域情调

根植于西部大漠地理空间,雪漠的"大漠三部曲"在对自然、动植物的民间化、传奇化书写中,沉潜着现代文明的反思与家园意识的建构。叙事策略上的文化空间间离与时间对峙的审美间距,生成的是敦实厚重的异域情调之美。对大漠村落的民间禁忌、方言土语、情爱悲歌的乡土本色书写,闪射出异域情调的文化忧郁意识。

Non-native plants in the understory of riparian forests across a land use gradient in the Southeast

As urbanization expands into rural areas, an increase in the number of non-native plant species at the urban-rural interface is expected due in large part to the increased availability of propagules from ornamental plantings. A study investigating the distribution of non-native plants in the understories of riparian forests across an urban-to-rural gradient north of Columbus, GA was initiated in 2003. A significantly greater number of non-native plant species occurred at the urban sites and at one site at the urban-rural interface, where 20 to 33% of the species encountered were non-native. In contrast, at the more rural sites non-native species comprised 4–14% of the total number of species. However, the importance values of non-native species as a whole did not change significantly across the land use gradient due to the high frequency and abundance of three non-native species (Ligustrum sinense, Lonicera japonica, and Microstegium vimineum) in the majority of the watersheds. Reductions in species richness and overstory reproduction associated with these non-natives could impact long-term forest structure and ecosystem function.     

古代仙草叙事的生命意识及生态伦理意蕴

明清小说植物生态叙事中的仙草可分为返生（重生）草系列、长生草系列和疗病草系列。仙草奇特的疗救、甚至起死回生功能,与古代中医的实践经验密不可分,其神秘感往往还同当事人的命运联系起来,即植物、动物昆虫与人类之间存在着某种生命体内在有机联系,借助植物的“生命素”来维护、延续人类有机体。除了仙草还有类似的珍稀植物,如肉芝。人参、枸杞精、茯苓等相关文献载录历史悠久,因叙述者文化背景不同而不免各有侧重,或盲目艳羡幸运者,或藉以传达伦理好尚,或彰显自身族群优势等,本土影响主要来自仙道信仰。     

Beneficiaries’ aspirations to permanent employment within the South African Working for Water Programme

The South African Working for Water (WfW) programme is a short-term public works programme (PWP) focused on clearing invasive alien plants, while training and empowering the marginalised poor to find employment. Furthermore, it aims to develop independent, entrepreneurial contractors who should ‘exit’ from the programme into the broader labour market. However, evidence indicates that many beneficiaries have become financially dependent on this employment, and find it difficult to search for alternatives. Understanding the reasons for this dependence from the perspective of the beneficiaries of this PWP is crucial to align such projects to the actual needs of the beneficiaries, but these have not yet been considered from a sociological perspective. This article reports on data collected, through face-to-face interviews, on WfW beneficiaries’ aspirations to permanent employment in four projects in the Winelands and Overberg districts of the Western Cape. It presents the novel finding that the social structures within projects themselves seem to create a need to remain in the WfW programme. In addition, a misalignment between these projects’ implementation and beneficiaries’ aspirations to financial stability (associated with permanent employment in WfW) is highlighted. The authors argue that WfW should respond to these aspirations, rather than pursue the ostensibly unrealistic aim of creating independent entrepreneurs. Finally, the implications of these findings for PWPs globally, and their concerns regarding the inadvertent creation of beneficiary dependence, are outlined.
