    对于采用桩基的各类结构,按承台埋没于地基土体与否,可区分之高、低承台桩基形式。在许多实际工程中,因回填土或欠固结土地基的继续沉降,或因土体流变或场地震陷等后沉降效应,均可致使承台与土体接触解除,即先前按设计采用的低承台桩基可能转为高承台形式。在静力条件下,这将导致桩身产生负摩阻力而降低其部分竖向承载能力;然而,在地震作用下,通过开展离心机地震模型试验和AbAQuS计算分析发现:当承台与地基土体脱离时,桩基最大弯矩设计值将会增大,且弯矩有效深度也将变深;并且,基础(承台)周期明显延长,充分表明高、低承台桩基形式地震行为差异迥然,高承台桩基形式较之相应低承台情况更为不利,在抗震设计时应充分予以认识、考虑。The pile foundation could be classified into the high or low types according to the position of cap relative to the surface of grounds.In many engineering practice, the settlement of unconsolidated clay or backfilled soil after construction,the soil rheology or the seismic field subsidence may lead to the separation of the cap from the clay surface, i.e., the cap was embedded originally into clay to a new state of high cap pile foundation.For the static condition,this kind of separation may result in the negative skin friction force along the piles and reduce the vertical bearing capacity of piles.However, under the seismic shaking condition, the centrifuge shaking table experiments and simulation with ABAQUS on both the cases indicated that piles underwent a higher maximum bending moment and a much larger active depth under high cap case than those at low cap case.This suggested that the embedding condition played an important role in the seismic response of pile-cap foundation.It becomes more disadvantageous when the embedding condition of the cap changes from the low cap case to the high cap case.国家自然科学基金资助项目(51209180); 成都理工大学地质灾害防治与地质环境保护国家重点实验室开放基金(SKLGP2012K014); 厦门大学大学生创新创业训练计划项

    本研究之主要目的有二:首先是調查惠蓀林場中的兩條主要溪流-關刀溪與北港溪中的溪流魚類種類,其次是將捕獲的溪魚攜回研究室中蓄養,探討蓄養的環境條偉並評估蓄養之可行性。調查結果發現在關刀溪與北港溪中的溪流魚類有九種,皆為臺灣原生種,其中七種並為特有種,一種保育性魚類。由惠蓀林場帶回研究的溪流魚類在水族函內以循環過濾水配合人工飼料投餵,在穩定的水溫及光週期下,已能成功飼育臺灣頜魚、臺灣石□、粗首□、臺灣馬口魚、赤斑吻蝦虎及臺灣鮠等六種溪流魚類。此一研究結果可供做為日後動態展示之基礎資料。Fishes were collected form two main streams-Guandau and Beikang-in the Hui-Sun Experimental Forest. The fishes were then transported to the laboratory and tested for the feasibility of raising. A total of 9 fish species were recorded. Among them, 7

    本研究從傅柯統管理性(governentality)理論及Beck的風險社會與反身性現代化理論的角度,來討論在全球生產網絡之下台灣高科技產業發展歷程裡的國家角色問題。做為國家培植重點策略工業的高科技產業,被社會認為是先進、低污染、高獲利的產業。由於發展型國家統管理性的成功運用,讓台灣在高科技產業全球生產網絡中佔有一席之地,成為東亞後進國家發展典範之一。高科技產業也成為1990年代後台灣成長最快,投資金額最高的產業類別。透過理論回顧與個案分析,本研究希望藉著分析國家機關、公民社會等重要行動者的相關文獻、報導、論述與行為來回答下列問題:在全球生產網絡下,國家機關扶植高科技產業的政策背後隱含著何種價值?在台灣發展歷程中,新自由主義以及發展型國家如何逐步成為國家理性和統管理性?當風險社會逐漸形成,國家機關又如何回應新興風險帶來的衝擊?針對高科技產業發展帶來的新興風險,公民社會透過何種方式途徑去制衡影響國家機關以改變舊有統管理性? 本研究認為在台灣經濟發展過程中,由於退出聯合國與中美斷交等因素的衝擊,國民黨政府統治正當性逐漸減弱。為了持續統治台灣,重視經濟發展的新自由主義遂取代單純的維持政權存續而成為國家理性。國家機關透過引進技術、排除障礙和提供優惠等政策手段,在加上威權統治下對公民社會、環境與勞工權益的忽視和壓制,來引導和扶植高科技產業發展。本研究藉由檢視了霄裡溪污染、中科三期、中科四期與日月光污染等高科技發展過程的重大爭議案例。發現雖經過政黨輪替,但後續執政的民進黨政府仍接續運用過去的發展型國家統管理性,透過土地徵收設立科學園區、提供租稅優惠和維持低度環境管制方式來促使高科技產業繼續擴張。但在民主化後,高科技產業發展過程中所產生的風險及副作用也逐漸於公民社會浮現,產生統管危機。而促使倡議團體與居民緊密合作,透過行政、立法、司法、監察與國際供應鏈施壓等方式,利用國家機關內部的相互制衡關係。希望能改變過去政府只注重經濟發展的發展型國家統管理性模式,使其朝向重視多元價值與風險管理的反身性統管化方向改變。雖然其一時之間仍無法完全跳脫舊有模式,但由於預警原則、資訊透明公開和公民參與等帶來統管藝術與管制技術的創新與變革,使統管理性能漸往反身性統管化的方向前進。藉由面對和處理新興風險歷程中的多元價值激盪與衝突,新自由主義國家理性亦逐漸受反身性現代化影響而改變。國家機關應體認除了發展經濟外,其亦有保護環境、保障人民健康與社會安全的職責,故應成為促使社會各種價值平等對話的價值平衡者。在科技與產業生態快速變化的今日,其亦應了解已無法再預先規劃經濟發展路徑。而必須以建構並維持公平、安全的產業發展環境來替代過去方式。成為「價值平衡者」以及「公平安全產業環境的建構者」,才是國家角色的新定位

    在2006年1月,立法院通過了總金額合計高達1410億水患治理特別條例、石門及其集水區整治特別條例。本文以許多民間非營利組織為監督治水預算成立的1410大禹治水聯盟為研究個案,希望能瞭解立法過程裡,民間聯盟如何監督公共政策?又如何打破國會與官僚的結盟結構,實際影響政策?本文採用深度訪談、報章資料與參與觀察等方式,藉由McAdam的政治機會結構理論為分析架構,以說明治水預算裡行動者擴編預算的動機與過程。並分析在立法院審查各階段治水聯盟的因應策略、實際行動和內部運作,以及監督成效。研究發現在地方水患陰影下,又面對官僚、國會與地方政府三者鐵三角般的互利合作,主張審慎監督的治水聯盟其實無力回天。一方面因議題範圍實在太大,無法動員特定地區相關者;另一方面也是鐵三角間同盟關係非常穩固,國會遊說發揮不了作用。故只能藉少數友好立委,在朝野協商爭取加入更多資訊公開、績效評估與公民參與機制。透過這些機制,在後續八年政策執行過程中找出更多公共參與和監督的著力點。藉此也讓原先僅有地區性互動的環保運動與社區大學運動在本案上交會。此新合作方向是否會對未來環保運動帶來新的在地網絡與群眾支持,值得後續觀察與研究。In January 2006, the Legislative Yuan passed the Special Enactment on Flood Management in Areas Susceptible to Floods and the Special Enactment on Restoration of Shi-Men and its Catchments Area amounting to NT$141 billion. This paper makes a study of the 1410 Ta-Yu Water Management Alliance formed by a number of civil non-profit organizations for the purpose of supervising and auditing the water management budget. The study seeks to understand how the civil alliance supervises public policies during the legislative process and how they break the alliance structure between the Legislative Yuan and bureaucracy to actually influence policies. By using McAdam’s political opportunity structure theory as its analysis structure, this paper gives an account of the motives and processes of activists in the creation of the water management budget through in-depth interviews, newspaper reports and participate observation. It also analyzes the countering strategies, activities, internal functioning and the results of the supervisory actions of the Water Management Alliance. This research discovered that in the face of the alliance’s proposition of prudent supervision could not be upheld in the face of mutual cooperation within the iron triangle of bureaucracy, the Legislative Yuan and local government. On one hand is the alliance’s inability to mobilize related parties in specific areas due to the issues covering too wide a range and on the other hand is the solid relationship within the iron triangle alliance and negates lobbying efforts in the Legislative Yuan. It is only by a few friendly legislators that mechanisms for the increased disclosure of information, performance evaluation and civil participation were added during negotiations between the ruling and opposition parties. Through these mechanisms it is hoped that more foothold for public involvement and supervision can be found in the following eight years of policy implementation. Also, such mechanisms would allow conservation movements and community college movements which used to be limited to territorial interactions to meet. Whether this new direction in cooperation brings new grassroot support for future environmental movements remains worthy of follow up observation and research

    自2014年政府提出金融業「打亞洲盃」的政策願景後,金融業開始更為積極的構思如何佈局東南亞,其中證券業因國內市場經營不易,證券市場逐漸萎縮,因此更急需往國外發展,開拓業務範圍。唯東南亞國家多因語言差異、風俗習慣隔閡,及資訊取得不易等因素,台灣證券商在缺乏資訊的情況下難以判斷應佈局於何處,以及應如何佈局,故本研究藉由蒐集各國文獻及資訊之文獻分析法,統整分析後提出台灣證券業佈局東南亞可行的策略、方向,從最基礎的經濟環境切入,分析潛在市場規模大小和未來成長潛力,找尋合適的佈局標的,擴大經營版圖,擺脫台灣證券市場萎縮之困境,並建構出適合台灣證券業之國際化經營發展策略,期能與國外證券商分庭抗禮,乃至於發展為亞洲區域型券商。Since Taiwan government announced that financial sectors competing across Asia in 2014, Taiwan’s financial institutions has worked more aggressively on how to reaching out to Southeast Asia. Especially for securities sectors, Taiwan’s securities firms need to expand business abroad because Taiwan’s securities market are shriveling. Because of the shortage of data and difference of languages, it is difficult for Taiwan’s securities firms to do research in finding out appropriate target market to invest in. So the purpose of this study is to find out the most appropriate target market to invest in for Taiwan’s securities firms. This study found out the best entry target and the development strategy for Taiwan securities sectors to develop into regional securities firms in Asia by case study between international level securities firm and Taiwan securities firm
