This exploratory study seeks to understand childhood in Hong Kong in relation to the high-rise living environment and dominant parenting culture among middle-class professionals. The empirical results suggest that it is parenting culture rather than the built environment that creates children's busy, scheduled lives, high levels of adult supervision and limited outdoor play. Building on a strong portfolio is considered to be both necessary to enter the popular British educational system and to counterbalance a curriculum that is supposed to offer less structured learning compared to the local Cantonese schools. It is argued that this paradoxical situation must be understood in the context of parents' personal childhood histories and the highly competitive global labour market in Hong Kong. The paper ends with a reflection on new discourses of childhood that creates cities and its many consumption spaces as urban idylls for raising children.  相似文献

In the tourism studies literature, wilderness has been addressed from two perspectives. From the first, human, perspective wilderness is a social, subjective construction that exists only in the mind of its users. From the second, ecological, perspective it is a material, objective reality. Here, we compare these two perspectives based on data collected in one of Poland's most popular nature-based destinations, The Great Masurian Lakes region, and develop a methodological framework which would operationalise this comparison and make it measurable. The research approach combined a survey of tourists and mapping of natural features. The data was analysed, first, to verify whether stated preferences regarding nature and the natural features surrounding tourist accommodation were coherent; this resulted in the construction of a Coherence Index (CI). Second, we analysed how stated preferences with respect to nature were linked to outdoor recreational activities; this was measured by a Nature Cruciality Index (NCI). Finally, both indexes were mapped and their spatial distributions were analysed. The findings showed that the subjective, social construction of wilderness does not always correspond to objective reality. Although tourists declared natural environment to be very important to them, in some cases the analysis found a lack of consistency between expressed preferences and the natural features found around accommodation. The phenomenon was mainly found in towns, where tourists were most nature-indifferent. Moreover, they were not interested in activities with high NCI. In some cases, however, the two perspectives were coherent, especially among nature-oriented tourists who stayed near lakes and those who stayed in villages (who were most conscious of their choices). Tourists who stayed near lakes undertook the most nature-crucial activities. These findings can be used to enhance local planning, management and marketing strategies for nature tourism.  相似文献

本文以珠江三洲为研究区域,以顺德市北窑镇为实例,就乡镇工业发展对一个镇域地方经济产生的影响进行了研究。认为在一些乡镇工业部门的发展过程中,可以作为一个"增长极",通过前后项生产联系有效地带动地方农业和第三产业的增长,从而形成地方的多种经济活动空间集聚体。因此,地方政府在选择其经济增长极时需对其与其它经济部门的前后项生产联系作周密的考察。  相似文献

陕西临潼康家龙山文化遗址1990年发掘动物遗存   总被引:2,自引:1,他引:1  
一、前言 陕西临潼康家遗址是龙山时期的村落遗址,面积约19万平方米。自1981年以来,曾进行过多次发掘①,出土了大量动物骨骼,本文将分析1990年夏秋两季发掘中出土的动物遗存。 1990年发掘是在遗址的中南部进行的,发掘 10 × 10米探方1个(126)。康家遗址T26的龙山地层厚度约3米,发现迭压多层的房屋一排,房前的院子里有许多灰坑。大部分兽骨出于灰坑和房屋的夯土墙内。发掘报告尚未发表,但为叙述方便本文根据建筑遗迹的分布情况初步将龙山文化地层分为早晚两期。早期:厚度约2米,每层房基包括4间房屋…  相似文献

This article presents an evaluation of coprolite specimens from the Lower Pecos canyonlands as records of individual dietary decisions. Prior studies of coprolites from this region have greatly expanded our knowledge of Archaic subsistence patterns, but have not taken full advantage of the record of individual dietary decisions recorded in each coprolite specimen. The menu, or dietary combinations, reflected in individual coprolite specimens are assessed through the identification of several congruent botanical components derived from the same food resource, phytoliths, fiber ultimates, and epidermal sheets. The data is analyzed with hierarchical cluster analysis, an exploratory statistical technique. The resultant menus reflected in these clusters are evaluated with reference to a diet-breadth model developed for the known staple resources of the canyonlands.Three main menus are apparent in the specimens. The first menu consists of prickly pear (Opuntia sp.) cladodes, or nopales, and was principally, although not exclusively, consumed in the late spring. This menu is primarily consumed when other resources were not readily available and may be considered a dependable but undesirable meal. The second menu consists of pit-baked lechuguilla (Agave lechuguilla) and sotol (Dasylirion sp.) caudices, or hearts, common throughout the cool season. This menu entails high processing costs, but would provide a reliable caloric return. The third menu exhibits a monolithic reliance on prickly pear fruits, or tunas, during the summer. The ease of harvest and consumption is reflected in the seasonal dominance of this resource, which was assuredly a highly desirable meal. The dietary patterns recorded in the coprolite specimens from the Lower Pecos canyonlands demonstrate a seasonally variable diet-breadth that incorporated low-ranked resources during times of seasonal scarcity as well as a monolithic dependence on high-ranked resources when they were available in the local landscape.  相似文献

采用相差分析方法,区分出禾本科植物中的农作物花粉;通过对青海互助丰台卡约文化遗址文化层和丰台村周围现代表土样品的孢粉分析,发现孢粉组合中有农作物花粉,反映人类农耕活动对聚落及其周围孢粉组合有明显的影响;文化层样品的孢粉组合显示,卡约文化早期阶段,禾本科植物花粉明显多于晚期阶段,可能反映了卡约文化时期(约公元前1200-800年)农业在社会经济中地位逐步下降的过程;孢粉组合还显示,与现代丰台村相比,卡约文化时期,聚落周围有更多的禾本科植物生长,人类可利用的植物资源比现代丰富。研究结果将有助于综合研究西北地区青铜时代环境与人类文化的关系。  相似文献

This study of Middle Palaeolithic assemblages from the Rhone Valley, in the South-East of France, increases our understanding of Neanderthal subsistence strategies and modes of territorial organisation by comparing a wide corpus of human occupations in limited chronological and geographical frameworks. The Neanderthal occupation modes may be examined using sites located in a reduced area, linking medium-altitude territories (Massif Central and the Alpine foothills) to the Rhone corridor. Through the combined analysis of the occupation levels of ten sites, all dated to between Marine Isotopic Stage (MIS) 7 and the beginning of MIS 3, we identify three types of occupation durations: (1) type 1 as long-term residential camps, (2) type 2 as short-term regular hunting camps and (3) type 3 as brief stopover camps. We discuss this variability of habitat types according to various parameters: site age, technical behaviour, environmental conditions, and site localisation and occupation seasons. The aim is to discern the underlying motivations behind Neanderthal group mobility. One of the main features of the Rhone Valley area is the great homogeneity of behaviours reflected within the sequences. This homogeneity, linked to the variability of the site occupations, supports the hypothesis of Neanderthal groups anticipating their land use requirements, and furthermore suggests that another type of circulating model was used in this area.  相似文献

Native American responses to Spanish colonialism are explored through an analysis of multiple lines of evidence concerning subsistence practices, diet, and health in the Salinas Pueblo area of central New Mexico. Zooarchaeological and paleoethnobotanical data from three Pueblo villages that experienced different degrees of Spanish missionization are the focus of this study. In addition, human osteological data from one village provide important information on activity patterns and health. These data are used to document the kinds of changes that occurred in Pueblo labor patterns, food consumption, and health from the pre-colonial to colonial periods. Synthetic analyses document the development of some degree of inter-village specialization in large game hunting, hide processing, and corn farming, presumably in response to Spanish tribute levies in corn and antelope hides, and demands on Pueblo labor in other arenas. There also appears to be a degree of divergence in women’s and men’s lives in the colonial period. These southwestern data are then compared with similar information from the southeastern US to identify patterns of similarity and difference in Native American experiences of and strategies for dealing with Spanish colonization.  相似文献
