In this study, both qualitative and quantitative methods were adopted. Research data were collected from classroom observations, questionnaires, interviews and student portfolios. The results not only revealed the students’ improvement in a range of skills but reflected change and growth over a period of time. The study showed that portfolio assessment provided students with self-directed learning, created an interaction for instruction and assessment and offered opportunities for peer-supported growth. As for future implementation, portfolio assessment is not an educational panacea; rather, it is a promising alternative assessment procedure, and instructors must fully realize both its strengths and weaknesses for proper implementation. In conclusion, the study found that portfolio assessment linked assessment more closely to classroom activities. In addition, the students’ participation and academic achievement were satisfactory.

個股的動態價量關係 - 以台灣股票市場為例

李苓碩 Unknown Date (has links)
We utilize the model of Llorente, Michaely, Saar and Wang (2002) to exam the dynamic volume-return relation of individual stocks in Taiwan stock market. In the LMSW (2002) model, investors trade to share risk and speculate on private information, and the show that hedging trades generate negatively autocorrelation returns, whereas speculative trades generate positively autocorrelation returns. We use daily volume and return data of stocks listed on TSEC to test the prediction of the model. Our results, which are consistent with LMSW (2002), show the cross-sectional variation in the relation between volume and return autocorrelation is related to the degree of information asymmetry. When we use some difference proxies of information asymmetry to test, the dynamic volume-return relation in Taiwan still consists with the theoretical prediction of LMSW (2002).

猜測變量與中間財傾銷行為

彭巧雯 Unknown Date (has links)
根據兩國中間財市場為相互區隔及非零猜測變量的假設下,本文建立一個兩階段賽局模型,並利用倒解法求解,分別在:一、在本國中間財市場中的兩國廠商均持非零猜測變量;二、在本國中間財市場中的本國廠商持非零猜測變量;三、國內廠商持非零猜測變量等三種假設情況下,探討廠商問的勾結行為與傾銷之間的關連性,以及勾結程度對傾銷程度的影響。結果發現,即使在最終財生產成本相同的情況下,勾結行為的存在亦會造成廠商在兩國市場中的定價不同,而導致較不具競爭性之國家的廠商會傾銷較具競爭性的另一國。其次,再將最終財成本差異納入模型,發現當本國中間財市場的廠商相互勾結以及本國最終財生產成本顯著高於外國這兩個條件同時滿足時,才會導致外國中間財廠商傾銷本國市場。此外,若兩國廠商在被傾銷國市場進行勾結,傾銷程度將會降低。

專利權之衡量與評價-以某記憶體模組公司為例 / Measurement and valuation of patent-by taking memory module company for example

蕭鈞昱 Unknown Date (has links)
隨著知識經濟時代的到來,無形資產對於企業決策的重要性與日俱增,其中無形資產裡的專利權是企業維持競爭力的一大利器,因此對於專利權進行衡量與評價是未來每個企業都必須面對的課題。 專利品質之衡量透過專利品質衡量表之設定,透過資料庫數據與專利說明書內容以及客觀存在之事實,客觀衡量標的專利之專利品質;輔以透過訪談與作者主觀判斷所得之主觀性衡量結果,綜合主客觀衡量結果,衡量出專利之品質。 專利之評價首先透過可評價性測試進行評價模式媒合,找出適合之評價模式,再為適合之評價模式設定出各項評價參數並實際計算出專利權價值數字,將評價與衡量結合,建立一套完整的專利權價值評估系統。 本研究分別以不同特性之專利組合為研究標的。經主客觀考量後,決定專利品質。評價上專利組合透過可評量測試後分別以市場法與收益法進行評價,針對各項參數進行設定說明與假設進而計算出實際數字並分析之。 經過衡量與評價後,本研究將針對各項衡量指標做出一適用性結論,並選出最適用於實務界之評價模式。 關鍵字:專利權、衡量、評價 / With the era of knowledge economy, intangible assets play an important role in corporate decision-making.Intangible assets in which the patent is the company to maintain a major competitive weapon, so the measurement and valuation of patents which every business must face in the future. Patent quality is measured through the setting of data such as database about patent and the content of patent specifications and the existence of objective facts.By enforcing the measurement way I mentioned so that I can get a objective outcome. The valuation of patent start from valuation test.The purpose of valuation test is matching a suitable valuation mode to valuate.After valuation test,I will set out the parameters to calculate the actual number of patent value.Finally,I will combine measurement and valuation to establish a patent evaluation system Through objective and subjective consideration,I make a conclusion for patent quality. After valuation test,I chose market method and income method to valuate.Through the setting of parameters and assumption,I calculate the actual number to approve the feasibility of valuation mode. After measurement and valuation, I will focus on the applicability conclusion of the measurement index and select the most suitable valuation model for practitioners.

遞迴支持向量迴歸資料縮減法 / Recursive SVR data reduction

江政舉 Unknown Date (has links)
近年來,支持向量機(SVM, Support Vector Machine)及支持向量迴歸(SVR, Support Vector Regression)已被廣泛的應用在分類及預測上的問題,然而實務上常見資料過於龐大,而導致需要較長的計算時間及較高的計算成本。為了解決這樣的問題,Zhang等人(2006)及Chen, Wang與Cao(2008)發展兩種類型的資料縮減方法。前者為減少變數數量的遞迴支持向量機(RSVM, Recursive Support Vector Machine),藉由交叉驗證以及定義所謂的貢獻因子來找出重要的變數,而考慮僅利用重要的變數做分類。後者的方法稱為DSKR(Direct Sparse Kernel Regression),考慮在支持向量迴歸中,僅選取部份支持向量個數做預測,以達到資料縮減效果。本研究將遞迴支持向量機的方法延伸至支持向量迴歸上,此法稱為遞迴支持向量迴歸(RSVR, Recursive Support Vector Regression),藉由交叉驗證以及依據決策函數來定義各變數的貢獻因子,藉此選取出重要的變數,並且保留這些重要變數來做後續分析與預測。本研究將此方法應用於兩組實際的化學資料:Triazines及Pyrim,我們發現資料被大幅縮減,僅有六分之一至五分之一的變數被保留。而資料縮減後的預測效果,與利用整組原始資料來進行支持向量迴歸的結果相近,但較DSKR的結果差。 關鍵字:支持向量機,支持向量迴歸,資料縮減

消費幻想量表的修建與評估 / The Revision and Evaluation of Consumer Fantasy

謝易儒 Unknown Date (has links)
消費幻想的概念在近年來受相關研究者的注目而持續發展,但常僅止於概念探討 (Belk et al., 2003;李德儀, 2005) 或特定的高幻想族群之研究 (Martin, 2004),究其背後成因是缺乏幻想衡量工具。在國內研究學者黃依婷 (2006) 建製了第一份幻想量表,終使後續相關研究得以展開,但其幻想量表的建製流程、再測信度、效標關聯效度和幻想量表之構面,皆仍有可改善之處。故本研究的目的,是評估舊有之幻想量表,進而修正成一份具有良好信度與效度的幻想量表。 本研究選擇黃依婷 (2006) 在建製量表時第二次施測的問卷版本,接續評估幻想量表構面,並進行量表純化與信度效度分析,以改善量表之品質。卻發現量表的構面相當不穩定,而進行一次表面效度鑑定後,發現構面之設計確實存在部份構面之間的題項易混淆與部份題項和其所在之構面定義不符。故確定舊有之幻想量表施測版本有重新整理構面之必要,經回顧文獻與重新檢視量表之目的後,確認了「構面-要素」矩陣設計概念的幻想量表構面,並在經過兩次專家評估修正以融合舊版幻想量表部分題項與新設計之題項,組成新幻想量表之初稿。構面整理後之幻想量表初稿經確認構面與題項設計具表面效度後,便利用校園樣本進行三次小規模施測,以內部一致性信度分析和探索性因素分析結果純化量表,建製出正式研究之幻想量表。最後再於200位一般消費者施測,進行信度分析、驗證性因素分析與效標關聯效度後,建製出一套19題李克特形式五點尺度之幻想量表,整體之內部一致性Cronbach’s Alpha值為0.90,再測信度為0.81,涵蓋「取得距離」、「過去經驗」、「細膩程度」、「持續程度」四大構面。 另外,本研究回顧文獻發現幻想程度較高者,在想像力生動程度可能較佳,而可利用Marks (1972, 1973a, 1973b) 所建立之想像力生動程度量表作為幻想量表之效標,透過效標關聯效度分析,確認幻想程度越高,想像力生動程度也越高,而證明本研究修建之幻想量表具有效標關聯效度。最後利用幻想量表驗證幻想相關推論與命題,發現年齡越高,幻想程度越低;在幻想構面「過去經驗」與「細膩程度」間,並無顯著之負相關。 / The concept of consumption fantasy has continually been receiving attention and kept developing by researchers in relevant fields, but relevant research could only focus on concept development (Belk et al., 2003; Julia Lee, 2005) or specific groups with higher degree of fantasy (Martin, 2004) due to lack of instruments to measure fantasy. Research about consumption fantasy through quantitative method has been commenced after the first fantasy inventory was built by domestic researcher Huang I-tin (2006). Nevertheless, there is still room for further revision and improvement in the development process, test-retest reliability, criterion-related validity and the dimensions of fantasy inventory build by Huang I-tin. This study is aimed to access the traditional fantasy inventory and rebuild it into an inventory with better quality on reliability and validity. The second edition of pretest questionnaire used by Huang I-tin was chosen to conduct subsequent development of dimension assessment, inventory purification, reliability and validity analysis to increase the quality of fantasy inventory. The face validity analysis was executed due to the discovery of unstable of inventory dimensions, the result unveiled that some items in some dimensions are hard to distinguish and some items do not satisfy the definitions of their dimensions. Referring to literatures and reassessing the purpose of fantasy inventory due to the need of rearrangement of dimensions in this inventory, “dimension-factor” matrix of design concept was initiated, and the first draft of revised fantasy inventory was developed after two panel discussions held on the revision and integration of old items extract from old fantasy inventory with new designed items. Once the fantasy inventory had been proved to have face validity via dimensional assessment, three small-scale surveys, in which the respondents are composed of students, were executed to develop the formal fantasy inventory through internal consistency reliability and exploratory factor analysis aimed to purify the draft of fantasy inventory. After the small-scale surveys, 200 general consumers were chosen to conduct formal questionnaire survey, which included reliability analysis, confirmatory factor analysis and criterion-related validity analysis, to build a fantasy inventory containing 19 Likert-type items. Overall, the Cronbach’s Alpha of this inventory is 0.90; test-retest reliability is 0.81. This inventory covers four dimensions: the distance of “Accessibility”, ”Pass Experience Relatedness”, the degree of “Fineness ”, and the degree of “Continuity”. In addition, the degree of vividness of visual imagery is discovered to be the criterion of fantasy from literature review. By assessing criterion validity, the degree of vividness of visual imagery is confirmed to be fit for criterion of fantasy. Finally, for the test of thesis that older people have lower degree of fantasy; the result indicated that there’s no negative relation existing between the dimension of “experience-relativity” and the dimension of “the degree of fineness”.

大量解僱保護規範之研究

張躍騰, Chang, Yue-Teng Unknown Date (has links)
受到全球性經濟不景氣、資金與產業的出走外移不斷增加、高科技業成長趨緩、產業轉型以及雇主惡性關廠等諸多因素的影響,企業大量解僱勞工(包括關廠)已成為我國近年來日趨惡化的嚴重問題。加上我國加入世界貿易組織WTO在即,入會後所產生的衝擊恐怕將使我國企業和工廠大量解僱勞工之情形有增無減,更加惡化!大量解僱勞工之後果,不但使勞工個人所得中斷、對勞工家庭經濟造成立即性的危機外,其所產生的大量失業人口對於勞動與就業市場的衝擊及形成的經濟問題,還有後續引發的社會壓力更是整體國家社會所必須面對及處理的重要問題。雖然現行勞基法第十一條、第十三條、第十六條、第十七條等相關規定對於雇主因經濟性因素而解僱勞工已有規定,但其內容不夠明確、充實,且勞基法並未針對「大量解僱」有特殊的程序及義務規範,致無法滿足大量解僱勞工之特別保護規範需求,更無法落實保障勞工之權益。實際上我國行政主管機關亦並非不知現行法令並不足以落實保障勞工在遭到解僱、關廠和大量裁員時應有的權益及保護,而已在數年前即針對企業關廠歇業、大量解僱問題開始訂定相關法規命令(包括行政院『事業單位大量解僱勞工保護措施』等等,詳請參照本文第五章及附錄),但此等規範因缺乏具有實效的罰責規定,且亦未有任何進一步介入大量解僱程序之公權力決定,此等無法律上之拘束力來具體落實法規規定,實難以發揮太多實際效果!且觀察當前層出不窮的大量解僱、企業裁員和關廠歇業等事件,可謂根本漠視此等法規中之「預告」及與工會、勞工「協商」之義務!故如何確實建立一套有效保障勞工的大量解僱保護規範制度並提升成為立法層次,已成為我國刻不容緩的重要課題。 本文即本此意旨,從「勞工保護原則」及「勞工參與經營(產業民主)原則」之法理基礎思考的角度出發,擬就有關大量解僱之基本問題、具體內容及相關配套措施,藉由外國立法例之觀察、比較法研究,以及國內相關文獻、現行法規、大量解僱立法草案版本(包括立法委員賴勁麟版(勞陣版)『大量解僱保護法草案』以及工運團體工委會版『關廠及大量資遣保護法草案』兩個版本)進行分析研究與整理,以探討大量解僱保護規範應有的制度設計及應注意的相關問題。 探討大量解僱保護規範首先應釐清的問題是,何謂「大量解僱」?關於「大量解僱」之定義及標準如何?其次,關於大量解僱保護規範之思考順序與制度設計上應包括以下三個階段和範圍:第一、大量解僱勞工前─須具備大量解僱事由(符合現行法經濟性解僱事由以及解僱必要性);第二、大量解僱勞工時─大量解僱應盡之法定義務及程序性規範(如通知行政主管機關並提出解僱計畫書、『預告』及『協商』義務等);第三、大量解僱勞工後─勞工法定權益之落實與保障(本文以積欠工資、資遣費、以及退休金之法定權益為主要探討對象)。 本論文主要架構如下,除第一章為研究動機等緒論外,第二章為大量解僱保護規範之基礎思考,主要目的在於釐清大量解僱之概念與意義,以及形成本文所採大量解僱的定義、標準之見解為何;另對於大量解僱與其他相關名詞作一說明。第三章在探討大量解僱之相關法理;第四章為外國立法例上對大量解僱之規定的說明介紹;第五章為我國之現況之分析探討;第六章則綜合上述,提出本文之結論與建議,其提出之內容及保護規範重點包括有:1.大量解僱之定義及標準,採此標準之理由為何; 2.關於大量解僱前:現行法經濟性解僱事由之再檢討及大量解僱必要性; 3.關於大量解僱中:建立大量解僱保護之程序性規範及法定義務,其內容與基本要點為何; 4.關於大量解僱後:勞工法定權益的具體落實與保障,包括現行法之檢討、修法建議以及長期規劃之方向。

數值航攝資料控制之研究-以政治大學校區為例 / A Study on Control Surveying of Digital Aerial Photographic Data -- An Example of Cheng-Chi University Campus

黃琬瑜, Huang, Wan-Yu Unknown Date (has links)
台灣地區地小人稠,土地使用情況複雜,因此,土地管理為一重要課題。航攝資料具高空間解析力及幾何真實性之特性,若能快速取得,則有助於長期環境監測與土地永續利用。有鑑於此,本研究以機動性高之直昇機為載具,配合9cm焦距之攝影機,採用11.5cm ×11.5cm像幅之彩色正片,航空拍攝實驗區,並於拍攝前佈設空照標,且利用全球定位系統測定地面控制點。 本研究目的在探討小像幅數值影像於重建方位過程中,攝影條件之特性及地面控制之成果,此外,利用解析測圖儀與影像工作站不同量測方法對於空中三角精度影響,結果顯示小像幅亦可完成數值空中三角測量。數位法X、Y、Z方向之RMSE為0.097 m、0.090 m、0.161 m,解析法之RMSE為0.132 m、0.120 m、0.144 m。 / The objective of this thesis has been to investigate the feasibility of digital aerotriangulation using small format photos. A focal length of 9mm camera mounted on a helicopter with format of 11.5cm by 11.5cm color positives have been used for taking pictures of the research area. The premarked ground control points were surveyed by GPS. Photo control was executed using a Leica BC3 analytical plotter and an Intergraph ImageStation respectively. The coordinates measurements of photo points using the two instruments have been evaluated. Both of interior and exterior parameters computed from digital triangulation and digitized photos have been used to produce the orthoimage. The resultant orthoimage was then superimposed and compared with the existing 1/1000 digital map. The results have indicated that: 1. The RMSE of digital method were X = 0.097m, Y = 0.090m, Z = 0.161m; the RMSE of analytical method were X = 0.132m, Y = 0.120m, Z = 0.144m; 2. Digital aerotriangulation could be performed using small format photos.

過度反應或反應不足?台股之濾嘴法則實證研究 / Overreaction or Underreaction? : Empirical Study on the Application of Filter Rule to Taiwan Stock Market

嚴浩祖 Unknown Date (has links)
本論文以濾嘴法則應用在台灣股票市場,試圖揭露報酬率與成交量之間的關係。雖然在短期內可藉由過度反應獲取報酬,然而,報酬率與成交量的關係仍舊模糊不清,本篇引用的文獻並不足以解釋此研究的結果。另外,我們發現在近十年中,因流動性進行的交易,而非因資訊進行的交易,主導了台灣股票市場。 / This thesis uses filter rule on Taiwan stock market to uncover the relationship between return and volume change. Although the profits for overreaction in a short time horizon exist, the pattern of the combination of return and volume change is unclear. No theory mentioned in the literature seems to be able to fully explain the results in this study. Yet, we find that the liquidity trading, rather than information trading, dominates Taiwan stock market in recent decade.
