Garden plants that invade native vegetation can be a threat to native ecosystems. The species composition of gardens near the bush in Hobart, Tasmania, Australia is shown to relate to environmental variation and the attitudes of gardeners to their recreation, to native plants and to the bush. Four types of gardens are discriminated: the species‐poor shrub garden; the local native garden; the woodland garden; and the gardenesque. A group of gardeners who valued functional gardens, and the hard work in creating a garden, largely produced gardenesque outcomes. A strongly conservationist group of gardeners had native, woodland or shrub gardens. A group of gardeners who valued romance and privacy largely had woodland gardens. A small group of gardeners who liked gardens to create themselves, and preferred to minimize the act of gardening, tended to the shrub garden outcome. Plant species that invade the bush are least frequent in the more manicured shrub and gardenesque styles of garden than in the more informal local native and woodland gardens, in a dissonance between expressed attitudes and outcomes. Most of the most invasive weeds in the bush are shown to be independent of their occurrence in adjacent gardens, suggesting that integrated control programs involving both all gardeners within dispersal range, and bush managers, are necessary. The existence of a small number of respondents who see benefits in environmental weeds in their gardens, suggests that such programs would be ineffective without regulation, a solution offered by no respondent. However, regulation might be ineffective without community understanding, the raising of which was the main solution suggested by the interviewed gardeners. 相似文献

日本自19世纪后半期迈入近代以来,因国际环境和国内情势的诸种因素,曾出现了数次较为明显的民族主义思潮。历次的思潮在缘起和表现形态上虽然不尽相同,但民族主义的基本性质却无甚改变。近代日本的民族主义思潮,既是本民族意识觉醒的强烈表现,同时又较多地体现为对本民族精神的夸饰,有时甚至是对本民族利益的过度诉求,极易染上褊狭和狂热的色彩,甚至走向危险的境地。 相似文献

《国风》创办于九一八事变之后,终刊于全面抗战爆发的前夕1936年.其作者主要是柳诒徵、张其昀、竺可桢、秉志等身处南京、上海等地的东南学人.他们在国难非常时期,积极投身公众领域,围绕《国风》提出了人文与科学并重的救亡主张,尽到了他们\"对于国家之应尽责任\".《国风》认为日本对华侵略不会仅满足于东北三省,其对中国的全面侵略必将爆发.对此中国必须发扬固有文化,振兴民族精神;开展独立的科学研究,提高国力;注重加强国人的国家观念,动员民众,以巩固国防.与北方的《独立评论》相比,《国风》或有不及之处,但它的救亡主张注意到了民族文化与广大民众对民族救亡的重要,这又是其独特所在,也是其优于前者的地方. 相似文献

对日和约与朝鲜停战谈判 总被引：1，自引：0，他引：1
朝鲜战争的爆发迫使美国最终确定了单独媾和的对日和约新方针,并且期待战局好转而实现对日媾和;美国为了阻止中国出席旧金山会议,在对日和约签订之前采取了拖延谈判的策略;旧金山会议后美国急于停战,而因对日和约在远东陷入困境和被动局面的苏联和中国却决心在停战谈判中坚持强硬的和不妥协的立场,以便在朝鲜战场吸引和消耗美国的力量。这就是在冷战大背景下对日和约与朝鲜停战谈判之间的微妙关系。 相似文献

The efficiency of nonmetric (discrete) characters of the deciduous dentition in assessing affinities of human populations was investigated in seven population samples from western Japan. The Neolithic Jomon (the Late and Latest stages, 4000–2300 BP ), the Aeneolithic Yayoi (2300–1700 BP , divided into materials from the Tanegashima Island and other western Japan materials), the protohistoric Kofun (1700–1300 BP ), the medieval Kamakura & Muromachi (800–400 BP ), the early modern Edo (400–130 BP ) and modern Japanese were compared for 17 traits. From the analyses of univariate and multivariate comparisons, close affinities between the Jomon and the Tanegashima Yayoi populations and between the other Yayoi, Kofun, Medieval, Edo and modern Japanese populations were indicated. This result coincided with the results obtained from the investigations of permanent dentition. The Jomon and Tanegashima Yayoi populations showed high frequencies of middle trigonid crest and cusp 6, while the other Yayoi and post‐Yayoi Japanese populations expressed high frequencies of shovelling, cusp 7 and distal trigonid crest. As simple tooth crowns are characteristic of their permanent teeth, the traits abounding in the Jomon and the Tanegashima Yayoi deciduous dentition were unique to their deciduous dentition. Different gene frequencies in juveniles and adults, or a heavy functional demand on their deciduous teeth, may be responsible for this difference. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

The location and type of Japanese property investments in Canada are examined as a case study of the increasing globalization of property markets and the remarkable rise of Japanese international investors in the late 1980s. Unpublished official statistics and company interviews indicate investment patterns had uneven implications for Canada's cities and regions. Even though Toronto is often seen as Canada's world city, Japanese investors as a whole overlooked the commercial potential of its property markets. The majority of their real estate investments took advantage of Japanese tourism growth in Pacific Canada and were associated with hotels and golf courses in Vancouver and its surrounding region. The author stresses the importance of Japanese perceptions, as well as local opportunities and constraints, in shaping the geography of Japanese real estate investment in Canada. L'emplacement et le type des investissements japonais au Canada sont examinés comme étude de cas sur la globalisation croissante des marchés de biens et la mon-tée remarquable des actionnaires internationaux japonais à la fin des années 80. Les statistiques officielles non-publiées montrent des implications inégales dans les villes et les régions du Canada. Bien que Toronto soit considéré souvent comme la ville mondiale du Canada, les actionnaires japonais dans ?ensemble ont négligé son potentiel commercial. La majorité des investissements sur les biens immobiliers ont pris avantage de la croissance du tourisme japonais au Canada Pacifique, et fut liee aux hotels et terrains de golf à Vancouver et dans les environs de la ville. ?auteur souligne ?importance des perceptions japonaises, aussi bien que les occasions et contraintes locales, en façonnant la géographie de leur investissement de biens au Canada. Mots-clés: investissement de biens au Canada; actionnaires japonais; investissements immobiliers 相似文献

日本人真正的自我认识始于 19世纪中期 ,它成为日本在现代社会中自我认识的起点。明治时期基本形成了日本人自我认识的若干流派 ,它历经各个历史时期 ,总是以不同的形式顽强地表现出来 ,影响一直延续至今。明治时期日本人自我认识的突出特点是深受“国运”的影响 ,以至出现明显的偏差。明治初期日本落后于欧美时 ,其民族自卑感十分强烈 ;一旦成为强国 ,则转向另一个极端 ,民族主义极度膨胀 ,最终走上了军国主义的道路。 相似文献

This research report introduces the historical process of Japanese use of chemical weapons against the Chinese during the Second World War, which caused serious casualties and mass destruction. In addition, it also elaborates on the discarded chemical weapons' injuries to the Chinese people and their negative effects on environmental pollution. According to the Chemical Weapons Convention (CWC), which became effective in 1997, Japan should take responsibility for destroying all chemical weapons abandoned on Chinese territory. 相似文献

当前日本经济的复苏与风险 总被引：1，自引：0，他引：1
从20世纪80年代末到本世纪初的10多年间,日本经历了战后以来最为严重的经济衰退。泡沫经济崩溃后,为了恢复经济,20世纪90年代以来日本政府推出过大大小小的经济对策不计其数,经历了多年艰难调整后,改革取得了明显的成效,延续了10多年的经济衰退和停滞终于结束,实现了经济的全面复苏。但另一方面,当前在日本经济增长和复苏的过程中,潜在的危机隐患依然存在,经济复苏是否能够持续下去仍然是个悬念,不能排除经济增长减缓或出现新一轮衰退的可能。 相似文献
