恢复高考是教育战线拨乱反正的一个重要突破,是中国高等教育发展史上的一个里程碑,对国家、社会和个人的发展都产生了深远的影响。在恢复高考这一决策过程中邓小平起了关键作用。他吸取了"文化大革命"时期高等教育的教训,号召要完整准确地理解毛泽东思想的科学体系,领导指导思想和教育战线上的拨乱反正,为恢复高考扫清了思想障碍;推动党和政府做出恢复高考的战略决策,实现了中国高等教育史上的一次重要转折;领导整顿教学秩序,为创造良好的高等教育环境做出了重要贡献。  相似文献

“良妻贤母”曾经是近代日本女子教育的代名词,有知识、有文化,始终是近代日本妇女的“贤”与“良”的主要标准之一。其时的中国也曾受其影响,以培养“贤妻良母”为目标。然而,近代以后半封建、半殖民地的社会状况使中国妇女不可能像日本妇女那样,在相对安稳的环境下去接受教育和知识的熏陶。日本的“良妻贤母”与中国的“贤妻良母”不仅有着不同的内涵,也面临着完全不同的命运。  相似文献

This study explores the feasibility of using strontium isotope (87Sr/86Sr) analyses of enamel from domestic dogs (Canis familiaris) to investigate networks of exchange in the prehistoric Circum‐Caribbean. Dog teeth were obtained from burial and domestic contexts from two prehistoric sites (Anse à la Gourde and Morel) on Grande‐Terre, Guadeloupe (Lesser Antilles). Strontium isotope results were compared with local biosphere 87Sr/86Sr data at the scale of the site, island and archipelago. The isotope results indicate both local and nonlocal origins with three dogs (30%) identified as nonlocal (one from Anse à la Gourde and two from Morel). The variance in 87Sr/86Sr ratios of the nonlocal dog teeth is consistent with diverse multiple origins external to the island of Grande‐Terre but consistent with origins from other islands of the Lesser Antilles. The diverse origins of the nonlocal dog samples indicate that the prehistoric circulation of dogs occurred at multiple scales from regional to long distance. Significantly, the 87Sr/86Sr ratios of some of the dog teeth are comparable with values of nonlocal humans at Anse à la Gourde determined in previous studies. It is possible that these comparable 87Sr/86Sr ratios result from similar natal origins, for example if individuals were migrating to Guadeloupe with dogs. The results of this study contribute to an ongoing regional investigation of the economic, social and political roles of animals and animal remains and the multiscalar networks of prehistoric mobility and exchange in the Circum‐Caribbean region.

流动性的增强不但意味着人口、信息、资金流动强度增加,也意味着流动范围的扩大。在此背景下,以稳定的人口构成为基础的传统地域饮食文化区的边界也开始发生变化。同时,流动性也使多元地方饮食文化在空间扩散的基础上展开了互动与交融。本研究将除港澳台地区以外的中国全域作为研究区域,基于海量餐饮服务设施POI数据,运用核密度分析方法分析中国目前的流行菜系空间扩散格局并描述其特征,并从流动性视角阐释其形成与扩散的文化地理逻辑。研究发现,中国现流行的菜系主要包括川菜、湘菜、粤菜、东北菜、徽菜、云贵菜、西北菜、鲁菜;中国流行菜系的空间扩散格局具有差异明显、多中心发展的特点。其中,川菜、湘菜、粤菜数量多分布广;鲁菜、徽菜分布集中,扩散较少;东北菜、云贵菜、西北菜数量较少但分布范围广。这种流行菜系空间扩散格局背后的文化地理逻辑与流动性密不可分,人口、资金等的流动促使地方饮食文化在空间内扩散,同时也带来了地方饮食文化间的交融互构。  相似文献

1958年,农业中学最先诞生于江苏省.在"大跃进"运动的影响下,江苏省农业中学的学校数量及在校人数迅速膨胀,成为全国教育"大跃进"的一个重要组成部分和表现形式.在整个"大跃进"时期,江苏省的农业中学始终保持了一个庞大的规模,直到中共中央决定对国民经济实行"调整、巩固、充实、提高",其盲目发展的势头才得以遏制并开始逐步调整.  相似文献

Archaeological research in the Atacama Desert has recovered evidence of considerable cultural variability. This variability seems to have increased during the Late Intermediate Period (AD 950–1400). The oasis of Quillagua, located at the margins of the Loa River in northern Chile, between the Andes and the coast (70 km from the Pacific Ocean), has shown important evidence regarding this cultural diversity. The variety in the archaeological evidence found at Quillagua has been interpreted as the result of two different cultural influences at the oasis: the Pica‐Tarapacá who occupied the coastal and inland regions to the north of Quillagua and the Atacama who occupied the oasis and fertile areas southeast of Quillagua. Here, we present the results of stable carbon, nitrogen and oxygen isotope analyses of 23 individuals recovered from the Cementerio Oriente in Quillagua, in order to test whether the observed cultural variability is also reflected in diet and mobility patterns. Results from carbon and nitrogen isotope measurements indicate the importance of marine protein, as well as a contribution of maize in the diet of some individuals. Four individuals show low δ18O values, suggesting a possible highland or non‐local origin, whereas values for the remaining individuals are consistent with lowland populations. Together, the results support the idea that the Quillagua oasis represented an important site of interaction between the Tarapacá and Atacama cultures, with close contacts with the coast but also with the presence of individuals from the highlands.

Stable oxygen isotope ratios in archaeological human dental enamel represent an under‐utilised tool in the examination of changing climatic patterns in the ancient world. In the Oman Peninsula at the end of the third millennium bc , rapid aridification was accompanied by a breakdown in interregional trade relations; however, the human response to these changes is poorly understood. At the Bronze Age necropolis at Shimal in the United Arab Emirates, dental enamel from individuals interred in both Umm an‐Nar (ca 2700–2000 bc ) and Wadi Suq (ca 2000–1300 bc ) tombs underwent oxygen, strontium and carbon isotope analyses to examine how local inhabitants of southeastern Arabia responded to both environmental and socioeconomic change. While individuals from Shimal exhibit a clear shift in mean δ18Oc(VPDB) values from the Umm an‐Nar (−3.5 ± 0.6‰, 1σ) to the Wadi Suq (−2.4 ± 0.9‰, 1σ), corresponding 87Sr/86Sr and δ13Cap signatures display homogeneity indicative of continuity in Bronze Age lifeways. Together, these data highlight the ability of local communities to successfully adapt to their changing environs (in lieu of societal collapse or a shift to a more mobile lifestyle) in an effort to maintain their way of life.

This article explores the nexus between nationalism/regionalism and higher education policy at the subnational scale. Relying on a Critical Discourse Analysis, the study investigates how notions of national/regional identity are discursively embedded in the higher education policy discussions of Quebec and Wallonia. A comparative approach based on the distinct logics of subnational politics in both cases is used. Whereas Quebec is considered a quintessential example of ‘subnationalism’, the Walloon case is defined as a political regionalist movement. The findings reveal the permeation of substate identity interests in both Quebec and Wallonia's higher education policy discussions, underscoring parallels between them despite their diverging characters. At the same time, the discourse analysis sheds light on important distinctions in the manner in which this identity discourse is articulated. By juxtaposing identity politics in ‘nationalist’ and ‘regionalist’ movements, the study aims to bridge their conceptualisation and critically reflect on the categorisation of subnational movements.  相似文献

As the world population becomes increasingly urbanised and mobile, “third places” take on greater importance for incorporating new residents into their neighbourhood and reducing social isolation. The third place concept has been applied to a range of public space research and embraces informal public meeting places outside of home (first place) and work (second place). This article critically investigates the connection between community gardens and third place, applying a framework based on the characteristics of third places to qualitative case studies of three Australian community gardens. The article highlights the role community gardens can play as third places in alleviating some of the challenges associated with population mobility. The findings show that two of the case study community gardens exhibit all characteristics of third places facilitating informal interactions between people of the neighbourhood while one does not for reasons considered. Findings also suggest that third place community gardens act as dynamic sites of placemaking, helping to connect people to the place. Community gardens can function as third places with a communal purpose inclusive across socially diverse neighbourhoods, within and beyond the garden boundaries. The article suggests appropriate design and location features for community gardens that best facilitate third place interactions.  相似文献
