方慶林, Fang, Ching Lin Unknown Date (has links)
本研究旨在探討國民小學分散式領導對學生學習態度之影響,研究採用調查研究法,以臺北縣國民小學三至六年級級任教師為調查對象,預試問卷,共寄出210份預試問卷,回收199份問卷,回收率94.8%,扣除無效問卷5份,有效問卷為194份,,有效問卷比率92.4%,並以項目分析,二階驗證性因素分析、信度分析進行研究工具之研發。正式問卷發出748份問卷,回收665份問卷,回收率88.9%,扣除無效問卷42份,有效問卷為623份,有效問卷比率83.3%。並分別以平均數、標準差之描述性統計、t考驗、單因子變異數分析、皮爾森積差相關及結構方程模式等統計方式進行資料分析。 本研究獲致以下結論: 一、 國民小學整體分散式領導的現況介於符合和有些符合之間。各層面以成員的參與層面教師知覺程度最好,成員的動力層面較低。 二、 國民小學整體學生學習態度的現況介於符合和有些符合之間。各層面以社會科教師知覺程度最好,英語科較低。 三、 教師人口變項年齡、服務年資不同,知覺校長整體分散式領導達顯著差異。年齡越大,知覺校長分散式領導程度越高。服務年資的組間未達顯著差異。 四、 學校環境變項學校規模、學校區域、校長年資不同,教師知覺校長整體分散式領導達顯著差異。學校規模越小、學校區域偏遠、校長年資越小,知覺校長分散式領導程度越高。 五、 教師人口變項年齡、服務年資不同,教師知覺整體學生學習態度達顯著差異。年齡越大、服務年資越長,知覺整體學生學習態度越高。 六、 學校環境變項學校規模不同,教師知覺整體學生學習態度達顯著差異,事後比較,組間未達顯著差異。 七、 分散式領導與學生學習態度具有中度正相關。 八、 分散式領導對學生學習態度具有正向影響性。 關鍵詞:分散式領導、學習態度、國民小學 / This study aims to explore the relationship between the distributed leadership and students’ learning attitude in the elementary schools. The Survey Research Method is adopted, and the research objects are the third to sixth grade elementary school teachers in Taipei. A total of 210 pre-test questionnaires were distributed, with 194 invalid questionnaires. The effective rate was 92.4%. In this study, item analysis, second-order confirmatory factor analysis, and the reliability analysis are applied. 748 formal questionnaires are distributed, with 665 valid, representing 83.5% effective. With the use of SPSS 17.0 for Windows and LISREL 8.80 statistical software for analysis, descriptive statistics, t-test, one-way analysis of variance, and Person product-moment correlation, and Structural Equation Models were employed in this study, and obtain the conclusion as follows: 1. The overall current conditions of distributed leadership in the elementary schools are good. Objects perform the best in the teacher’s perception of the member’s participation aspect while the member’s motivation performs the worst. 2. The overall current conditions of students’ learning attitude in the elementary schools are good. Among them, teachers in the Social Studies perceived the distributed leadership the best while the ones in the English the worse 3. There is significant difference for different teacher characteristics such as ages, years of service to perceived the principals’ distributed leadership. The older the age, the level of the principal distributed leadership perception the higher. There is no significant difference among the four different year-of-service groups. 4. With the different environmental variables in the school scale, school area, and principal’s years of service, the teachers significantly perceived the principal distributed leadership differently. The smaller the school, the level of principal distributed leadership perception the higher. The same results are obtained if the remoter the school, and the smaller the principal’s years of service, which means the level of principal distributed leadership perception is higher. 5. There is significant difference in the teacher perception of students’ learning attitude with different teacher characteristics such as ages, years of service. The older the teachers’ age, the level of students’ learning attitude perception the higher. 6. With the different scales of schools, the difference achieves significance in the way of teachers sensing the students’ learning attitude. Through post-hoc comparison, there is no difference among groups. 7. Distributed leadership has a significant positive correlation with students’ learning attitude. 8. Distributed leadership has a significant positive impact on students’ learning attitude. Keywords: distributed leadership, learning attitude, elementary school

深度學習於中文句子之表示法學習 / Deep learning techniques for Chinese sentence representation learning

管芸辰, Kuan, Yun Chen Unknown Date (has links)
本篇論文主要在探討如何利用近期發展之深度學習技術在於中文句子分散式表示法學習。近期深度學習受到極大的注目,相關技術也隨之蓬勃發展。然而相關的分散式表示方式,大多以英文為主的其他印歐語系作為主要的衡量對象,也據其特性發展。除了印歐語系外,另外漢藏語系及阿爾泰語系等也有眾多使用人口。還有獨立語系的像日語、韓語等語系存在,各自也有其不同的特性。中文本身屬於漢藏語系,本身具有相當不同的特性,像是孤立語、聲調、量詞等。近來也有許多論文使用多語系的資料集作為評量標準,但鮮少去討論各語言間表現的差異。 本論文利用句子情緒分類之實驗,來比較近期所發展之深度學習之技術與傳統詞向量表示法的差異,我們將以TF-IDF為基準比較其他三個PVDM、Siamese-CBOW及Fasttext的表現差異,也深入探討此些模型對於中文句子情緒分類之表現。 / The paper demonstrates how the deep learning methods published in recent years applied in Chinese sentence representation learning. Recently, the deep learning techniques have attracted the great attention. Related areas also grow enormously. However, the most techniques use Indo-European languages mainly as evaluation objective and developed corresponding to their properties. Besides Indo-European languages, there are Sino-Tibetan language and Altaic language, which also spoken widely. There are only some independent languages like Japanese or Korean, which have their own properties. Chinese itself is belonged to Sino-Tibetan language family and has some characters like isolating language, tone, count word...etc.Recently, many publications also use the multilingual dataset to evaluate their performance, but few of them discuss the differences among different languages. This thesis demonstrates that we perform the sentiment analysis on Chinese Weibo dataset to quantize the effectiveness of different deep learning techniques. We compared the traditional TF-IDF model with PVDM, Siamese-CBOW, and FastText, and evaluate the model they created.

分散式股權結構設計對社會影響力投資機構發展之個案分析:以活水社企創投為例 / Decentralized equity structure design to the development of social impact investment institutions: A case study of 活水社企創投( B Current Impact Investment)

牛寶賢 Unknown Date (has links)
在整個創業環境當中,除了新創公司、政府法令、人才環境等元素以外,投資型機構 也是重要的角色,而所謂創投的分類,也將會因投資標的的不同而有所不同,其中以社會 企業的投資機構,一般我們稱之為「影響力投資機構」,其投資績效不完全以財務報酬為主, 而是會量化所謂社會影響力來做衡量,此機構隨著全世界社會企業的創業潮流,重要性日 益提高,特別的營運模式也開始陸續出現研究。 然而台灣最早在十年前就已有社會影響力投資的概念出現,且相繼出現了許多機構在 推動與執行,產業內具備專業知識與技術的前輩與人才數量更是不勝枚舉,看似不管是資 金還是相關資源皆不缺乏的情況下,回歸到實際執行面上的發展卻不甚順利,許多社會影 響力投資機構相繼地遭遇如營運上的問題,以致於不得不做出像是轉型或是退出市場的決 策,使得台灣有一段時間始終缺乏一個好的典範。一直到 2014 年活水社企投資開發公司(B Current Impact Investment)的正式成立,才真正突破僵局,為台灣的社會影響力投資與社會企業生態再度開啟了新的篇章。 本研究藉由質化訪談的研究模式,實際走入台灣社會企業的現場,面對面蒐集產業面 的經營資訊與競爭策略,暸解作對代表的活水社投是如何辦到的,以時間軸的形式將創立前中後不同期間的經營重點整理並分析,最後輔以經典的投資案例進行必較,將現今台灣最新個案轉為研究資料,最後發現關鍵成功因素為「分散式股權結構」的組織設計模式。 在此架構下的影響力投資機構可以充分發揮各股東的背景與專業能力,互相協調發揮 綜效,同時因應不同的環境與個案條件都能有很好的適應性,這是以往集中式股權結構的 公司無法辦到的,同時他們不斷因應趨勢變化,如今也從個別投資人到公司規模投資機構, 加大了投資基金規模與穩健性,也因此使活水社投得以在不易生存的產業環境下生存下來, 並持續成長茁壯。

適用於P2P檔案分享系統傳輸協定之設計 / A UDP-Based Protocol for Distributed P2P File Sharing

許弘奇, Xu,Hong-Qi Unknown Date (has links)
Peer-to-Peer(P2P)架構讓社群內的使用者收集分散在網路各處之資源,其中最為風行的P2P系統當屬P2P檔案分享系統。P2P檔案分享系統之架構可分為集中式及分散式,而分散式架構又可細分為結構化及非結構化兩種。採用分散式且非結構化之BitTorrent-like架構,因其可擴張性較佳而廣為風行。在經驗中發現,BitTorrent-like架構在非對稱網路之下雖擁有寬裕的下行頻寬,但是其頻寬使用率卻不高,我們分析其成因如下:(1) Fractional Upward Bandwidth (FUB) 、 (2)Blockage of Acknowledgement (BoA) 與 (3)Long Physical Paths 等。而其中的Blockage of ACK問題,現今尚未有研究學者提出完整解決方案。本研究之目的,即要針對此Blockage of ACK的問題,改良網路協定中的傳輸層 (Transport Layer) 協定以提昇P2P檔案分享系統之效能。我們改用UDP作為傳輸層協定,並在應用層加入自動重建遺失之封包、決定基本傳輸單位大小及決定資料傳送速率等機制,以彌補UDP之缺陷。文中並提供了傳輸協定運作時所需參數的估計法,並且也與其它傳輸協定做效能之比較。實驗結果發現,我們設計的傳輸協定確可改善P2P檔案共享系統的運作效能。 / Peer-to-Peer (P2P) architectures let participants gather resources form network and make participants acquire more computation resources than they could offer. One of the most prominent P2P systems is P2P file sharing system. P2P file sharing system could be classified into to 2 categories: centralized and decentralized model. BitTorrent-like (BT-like) model can be classified as decentralized and unstructured model. BT-like model is quit popular nowadays due to its scalability. Unfortunately, BT-like model has several shortcomings on performance over asymmetric networks, because of some problems, such as Fractional Upward Bandwidth (FUB), Blockage of Acknowledgement (BoA) and long physical paths. No complete solution is available yet to solve the BoA problem. We propose a new UDP-based protocol to alleviate this problem. Since UDP protocol is not able to guarantee the data-integrity nor to determine the proper transmission rate by itself. To offer a complete solution, we have to enhance UDP, to add extra capabilities such as packet loss recovery, segment size determination and data rate determination mechanisms. Experiments show that our proposed protocol has good improvement on performance.

住宅個案價格分散之時空影響-房價水準、景氣時機與區位條件之分析

許淑媛 Unknown Date (has links)
過去住宅價格的研究多以平均數為主軸,鮮少探討價格分散(price dispersion)的現象。然而,如市場上價格分散程度增加,則平均價格在市場整體價格的描述上將失去其經濟意義。因此,本文試圖了解平均價格與價格分散的關係及價格分散的影響原因。目前,價格分散之文獻多著重於需求者行為對成交價分散的影響,未探討造成表價差異的原因。過去文獻指出,景氣及區位皆會影響建商的推案行為及訂價行為。因此,本文從供給者角度,探討房價水準、景氣及區位對表價分散造成的影響。 本研究使用政治大學房地產研究中心與國泰建設公司所調查台北市與台北縣83Q1至97Q2住宅新推個案表價資料,分成台北市與台北縣市中心、市郊與郊外研究價格分散程度差異。結果顯示,住宅市場房價水準上升時,將增加建商的產品及訂價差異,在市場效率及資訊不足的情況下,使房價水準領先價格分散三季。而不景氣時容易對財務條件較差之廠商造成銷售壓力,使價格分散較景氣時大。區位較佳之地區因產品獨特性、價格僵固無彈性,而使分散程度小於區位較差地區。由市場上價格分散情形,我們可以觀察到市場風險的變化,景氣轉壞時或區位較差地區風險較高。 價格分散是市場上價格混亂的現象,在產品異質性較高故不易觀察的住宅市場中,本文釐清了價格分散來自於房價水準、景氣及區位。因此,當價格分散擴大時,學術上觀察平均價格時應更謹慎的看到個體的差異,而市場上需求者更應多搜尋與比較市場上的住宅產品。 / Price dispersion is a common issue in homogeneous goods literatures, but a few researches in housing market. In financial literatures, variation is an important index which means the risk of market. Especially in market depression, we should pay more attention to price variation. As a result, this paper focus on the price dispersion of housing market, and tries to find the effect of price level, real estate cycle, and location on price dispersion. Previous time-on-the-market studies focused on the relationship between listing price and trading price of housing unit, while this paper investigates the difference in listing price of different residential projects in new construction market. We demonstrate the degree of housing price dispersion which changes with price level, real estate cycle and location, because of the heterogeneity of seller’s strategies. After controlling the effect of product differentiation, we find that there is a positive correlation between price dispersion and risk. Our results suggest that besides the price level, we should pay more attention to the price dispersion of housing market.
