以广州荔湾区“六普”资料为根据,就人口高密度分布与社区建设的关系进行梳理与探讨。荔湾区“六普”数据显示,城区人口密度过高,成为影响社区生活的主要因素,给居民生命安全、公共生活质量与日常生活便利性带来负面效应。科学化与人性化人口密度干预是治理高密度人口问题的理性策略,如“跳出”社区视野,在城市“一盘棋”中均衡人口布局,在社区建设中,通过社区更新改造,增强人口承载能力,通过建构便利舒适人居环境,提升社区生活质量。 相似文献

The authors examined the central hypothesis that students’ early perceptions of support and sense of engagement in math classes and math activities strongly influence the broadening or narrowing of their math interest. The focus was on the first wave of qualitative data collected from 5th‐, 7th‐, and 9th‐grade students during the 2007–2008 academic year as part of a longitudinal study. Findings indicate the importance of using group work and extrinsic motivation in middle school math classes to broaden interest; peer classroom behavior was often a detractor of math interest. 相似文献

We investigated the emergence in infancy of a preference to imitate individuals who display confidence over lack of confidence. Eighteen‐ and 24‐month‐olds (N = 70) were presented with an experimenter who demonstrated the use of several objects accompanied by either nonverbal expressions of confidence or lack of confidence. At 24 months, infants were more likely to imitate the actions when demonstrated by a confident experimenter than by an unconfident experimenter; 18‐month‐olds showed no such preference. The experimenter then presented an additional imitation trial and a word‐learning trial while displaying a neutral expression. Twenty‐four‐month‐olds persisted in preferentially imitating a previously confident experimenter, but prior confidence had no effect on their word learning. These findings demonstrate a developmental increase in infants’ use of confidence cues toward the end of the second year of life. 相似文献

从想象、走进到反思:人类学视野下的“边缘”研究谱系 总被引:1,自引:0,他引:1
人类学视野下的"边缘"不仅是与"中心"相对的空间范畴,也是一种反思殖民主义、后殖民主义、西方霸权、现代性以及全球化的话语和研究范式。在从想象、走进到反思的演变过程中,"边缘"研究经历了从宏观到微观、从猜测到实证、从西方中心主义到多元化、从全球化到本土化的转换。 相似文献

认识储层岩石中含油饱和度及饱和度分布,对驱替机理的深入研究是非常重要的。为了搞清储层岩石在驱替过程中的饱和度分布情况,应用工业CT技术,提出了一种储层含油岩芯被驱替后的饱和度分布的CT密度差测量方法。在岩样的同一断面,分别对干岩样、饱和岩样及在驱替后的岩样进行CT扫描,重建相应的断层图象,测量所建图象的灰度值,计算出相应的密度值,用密度差法计算出饱和度及其分布值。在γ射线工业CT机“CD-300BG”上对某油田岩样进行了实际测量,获得的结果说明,采用CT密度差法测量饱和度分布是有效的。该方法与常规驱替法相比较,具有快速、精度高、无损岩样和能模拟地层状态测量等特点,是油田开发、油藏描述和地层评价的一种新的有效方法。 相似文献

In 2003, the Danish Ministry of Foreign Affairs undertook a decentralisation of the management of bilateral aid to the embassies in major partner countries. However, while decentralisation appears to live up to the principles of the Paris Declaration on Aid Effectiveness, the specific delegation of responsibilities as well as the political context of aid management may jeopardise the intended contribution to effective development co‐operation. This article explores some factors potentially limiting the usefulness of decentralised aid management in the Danish case, and discusses certain intra‐organisational dynamics and extra‐organisational pressures influencing ‘donor effectiveness’. 相似文献

This study tested a moderation model in which the association between child sexual abuse severity and negative sexual outcomes (i.e., sexual avoidance and compulsivity) differed as a function of relationships status (i.e., single, cohabiting, and married individuals). A sample of 1,033 adults completed self‐report questionnaires online, and 21.5% reported childhood sexual abuse. Path analyses indicated that child sexual abuse severity was associated with higher sexual compulsivity in single individuals, both higher sexual avoidance and compulsivity in cohabiting individuals, and higher sexual avoidance in married individuals. The moderation model was invariant across men and women. These results suggest that the time course of negative sexual outcomes associated with child sexual abuse may follow distinct patterns of expression according to relationship status. 相似文献

高等学校从产生的那一天起就面临着保守与创新的选择,但在近代化之前,高等学校远离社会而固守自己的象牙塔之时,这种选择的艰难性并不突出。当人类社会进入知识经济时代,高等学校所面临的选择就变得十分艰难。因此,正确处理好保守与创新的关系,是当代高等学校的重大战略决策,我国高等学校正处在这个关键时期。 相似文献

“Phil's Calling Grandma… ”: The Role of External Support in Human–Companion Animal Identity Pairings 下载免费PDF全文
Andrea Laurent‐Simpson 《Symbolic Interaction》2017,40(2):212-228
This exploratory paper deals with human–animal role identity pairings such as parent–child or sibling–sibling and the necessity of support from other actors both for the formation of these idiosyncratic identities, as well as for their situational placement in social environments not limited to the nonhuman animal. Taken from a qualitative study examining identity formation counter to the nonhuman animal, I use in‐depth interviews of both people with and without human children to demonstrate how human‐to‐human relationships are formed by categorizing the companion animal as a “child” of sorts within the family structure. These relationships prove integral to the continued development and enactment of identities such as the animal “parent” or the animal “sibling” via three different groups: their own parents, partners, and, in one case, adult siblings. This creates positive affect and commitment to the identity across other social situations. Implications of these findings for identity theory and family research are discussed. 相似文献
