    本文選取了在發展程度上呈梯次性的中國三個個案為研究對象，以合作主義和社會資源理論為理論視角，以非營利組織對社會福利資源的整合功能為切入點，探討了非營利組織整合社會福利資源的機制、其效果的制約性因素、以及在社會福利領域推動非營利組織發展的動力，認為定位明確的非營利組織的成立與運營為社會福利資源的整合提供了一條可供選擇的有效的途徑，發現在實踐中非營利組織可利用正式的和非正式的兩種網路建構來開發整合社會福利資源，而現階段其整合效果受到政策環境和自身能力等因素的制約，推動非營利組織發展與能力健全的力量源泉主要來自需求推動、政策推動、專業知識推動和國際交往推動。
  2. Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants

    文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映

  4. The engendering source of traffic volumes and their general influential factors have been presented, and the situation of nowadays highway transportation has been discussed. according to the introduction of traffic distribution theory and classical assignment method, analysis of traffic flow path selection among cities and that of special influential factors for traffic flow on toll highways, initial analysis to the forming mechanism of traffic volume on road sections has been made, and a probability model for path selection has been set up with the maximum - utility theory and disaggregating model. detailed analysis to impedances on road sections and their functions ( especially to three main composing factors of the impedances as cost of time, transport and toll and to the functional relations with traffic loads ) was made, at the same time, the relative cost calculating model was set up on the basis of the state - of - art achievements in both international and national researches
