明清以降来青早期移民的祖籍问题,民间和学术界一般都认为是在今天江苏省南京市、笔者以今天南京珠玑巷不可考为起点,经过对民间传说和历史资料的辨析查考,提出两种推论认为;所谓南京珠玑巷一是可能在今天浙江诸暨市(为同音之转),二是可能在今天河南省开封市(该地曾是旧县祥符)。由于自然和人文环境的变异、官方和民间话语修正的双重作用而使其发生了改变,并最终使这一文化符号在误读的情况下,被赋予了新的文化内涵。 相似文献

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States 总被引:6,自引:0,他引:6
Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations
in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining
the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical
sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study,
a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture
analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then
computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images
into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were
examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC
based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship
between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions.
Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable
measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively
correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research
should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and
urban thermal conditions.

自然和谐是道家生态思想的核心,围绕着自然和谐,道家生态思想主要呈现出三层面结构,即法天贵真的自然特殊态社会层、天而不人的自然中心态天人层和兼怀万物的完全态自然层。说明人类社会的本质是自然的,自然是世界的中心,万事万物包括人类社会的最高生态理想是完全态的自然境界。人类的天职是爱护自然、保护环境、维护生态、追求自然的生态和谐。 相似文献

Few measures parallel the robust depth offered in the existing multidimensional and ecologically informed theories of resilience. This study sought to evaluate the test–retest reliability, construct, and predictive validity of the individual, family, and community resilience resource profile (IFCR-R). The IFCR-R measures a family’s access to resilience resources and protective factors across multiple ecological levels. Confirmatory factor analysis was used with a sample of n?=?810 low-income families. And 159 families completed multiple time point measures for test–retest reliability and predictive validity evaluation. Results of this study support the proposed multidimensional ecological structure of the IFCR-R and found that the IFCR-R offers an acceptable test–retest reliability and predictive validity for outcomes of mental and physical health. 相似文献

As approaches to positive youth development (PYD) gain momentum, the issue of sexuality – a critical component of human development – is being subsumed by ideological debates. In the current political climate, sexuality education is often relegated to biological and/or values-based approaches, neglecting essential relational and collective aspects of sexuality. Through the explication of sexuality as an important component of youth's social ecology, this paper provides a conceptual link between the goals of the Sexuality Information and Education Council of the United States' (SIECUS) Guidelines for comprehensive sexuality education and those of PYD. We argue that sexuality, as a normative part of human development, culture, identity, and relationships, be approached from an asset-based perspective, rather than a deficit-based perspective. We propose a framework that illustrates how aspects of sexuality are embedded within PYD contexts, and demonstrates how a sexuality education program rooted in SIECUS guidelines can further PYD goals across community contexts. 相似文献

Ecological research can augment restoration practice in urban areas degraded by invasive species—examples from Chicago Wilderness 总被引:1,自引:1,他引:0

Urban biodiversity conservation needs a firm scientific foundation, one that draws upon active and regionally calibrated research
programs. Until recently this foundation has not existed. In this paper we examine the way in which the emerging discipline
of restoration ecology in an urban context can learn from the experiences of ongoing restoration projects and in turn how
novel insights from research of urban soils can help these projects define and reach their goals. Limitations on collaboration
between academic researchers and practitioners continues be problematic. We discuss a model whereby this impediment may be
removed. A case study of Rhamnus cathartica, an invader of Midwestern woodlands which modifies some important soil ecosystem properties will be used to illustrate the
potential for engagement between research and practice. 相似文献

Monitoring and evaluating international peacebuilding efforts have become more sophisticated over the past years, but still relies on managerial approaches that often do not capture the complexity of war, peace and the grey areas in between. The article argues that organizations should embrace qualitative approaches more widely and introduces ethnographic vignettes as one example to explain the complexity of post-conflict situations. By understanding the personal dimension, the life- and work-styles of international peacebuilders, the current evaluation discourse can become more meaningful-both for organizational learning and sustainable peace efforts on the ground. The article ends by highlighting some approaches that deserve more attention and that promise to help to critically enhance current and future debates about the evaluation of peacebuilding. 相似文献

‘North East India’ composed of different ethnicity is plagued with ethnic assertions and regionalism with that of centuries of alienation. Development is one big issue that need to be address in the region. The North East India after decades of independence is still lagging behind in term of socio, economic, education, political, cultural and social development. A deeper study reveals that movement for separate homeland, regionalism, tribalism, ethnic clash, crime, mass poverty, etc in the region are caused by backwardness of the region. The distinct geo-ethnic and socio-historical characters of North-East India constitute the hotbed of ethnic strife and extreme radicalism. The solution lies partly in resolving the conflict between primordial ethnic loyalties or ‘ethno-nationalism’ and the ‘nationalism of the nation state’, and partly a conscious and voluntary effort to resist corruption and unholy alliance between the militants and the politicians in the region. In any case, ethnic reconciliation would result in the reduction of ethnic violence of all kinds and would eventually restore law and order in the region. When the civil governance in the region will be spared from combating militancy or appeasing the militants, the whole energy of the government would be for strengthening the institutions of local self-government, which act as potential agents of development in the conflict-ridden states of the North-East India. 相似文献
