Liquidity and Asset Pricing: a new measure of liquidity and empirical study

本文指出资产定价除了包括Fama-French三要素外，还应加上流动性和私有信息。由于流动性的复杂性，现有的流动性指标主要集中于体现表示流动性的一方面特性，而本文构造了一个新的流动性指标LMx，这个指标体现了流动性的多方面特性，特别强调交易速度。这个新的流动性指标与通常使用的买卖价差、换手率和return-to-volume(RtoV)高度相关，但是本质上新的指标和现有的指标是不同的。本文用这个新指标证明了股市存在显著的流动性溢价，而CAPM和Fama-French三要素不能体现流动性溢价，并指出流动性风险是资产定价的重要因素。用二要素（市场和流动性）模型很好地解释横截面的股票收益问题。对二要...This paper indicates that the asset pricing model include not only the Fama-French three-factor but also liquidity and private information. Since liquidity is multidimensional, existing measures typically focus on one dimension of liquidity. A new liquidity measure LMx was constructed in this paper. This measure captures multiple dimensions of liquidity, with particular emphasis on trading speed. ...学位：理学硕士院系专业：数学科学学院数学与应用数学系_应用数学学号：20042306

大学生のひとり親家族のイメージ

近年、ひとり親家族が増加している。未婚、離別、死別など様々な状況にあるひとり親家族の多くは社会的偏見による問題を抱えている。そこでこの調査の目的は、「どのような変数が大学生のひとり親家族に対する意見に影響を与えているか」、「どのようなイメージを持っているか」に焦点を当てた。ひとり親に対する肯定的意見に,「世間のひとり親の肯定的イメージ」、「子どもがいて再婚することに関する意見」、「性別役割分業に関する意見」、「男女参画に関する講義の受講経験」、「ひとり親家族に関するメディアを見た経験」、「将来の結婚と子育てに関する意見」が影響を与えていた。性別分業に関する意見は、媒介変数として機能していた。ひとり親に対するイメージは、「親子早期自立イメージ」「親離れ・子離れイメージ」、「親子孤立イメージ」「親子共依存イメージ」であった。その中でひとり親の最も肯定的意見と関連があったのは、「親子共依存イメージ」であった。The number of one-parent families has been growing in Japan. One-parent families occur for different reasons. Some people are unmarried and are raising a family on their own, or they are separated or widowed. Many of these people suffer from social prejudice. The purpose of this research was focused on what variables are affecting university students’ opinions of one-parent families and to find out what their image is of single, separated or widowed　parents with children. There are a number of variables: society’s opinion of single-parents; opinions on people with children who remarry; opinions on gender roles; experience of taking classes on gender studies; one-parent families as reflected by the mass media; opinions on the students’ future with regard to marriage and having children and how these affected students’ opinions of single-parents and opinions on gender roles.There are four images of single parents with children. They are as follows: that children in one –parent families might be more independent; that the parents and children might be less dependent on each other; that there might be less communication between parents and children; that parents and children might be more co-dependent. In Japan, the most positive image is represented by the latter.原稿受付　平成22年1月15日原稿受理　平成23年2月5

東澳嶺崩塌地之地形演育分析

梅姬颱風 (2010) 與東北季風之共伴效應於台灣宜蘭縣蘇澳地區帶來了豐沛降雨，高累積雨量造成了台9 線蘇花公路群集性土砂災害，尤其在115.9K 上邊坡更誘發了約210 萬m3 之大規模崩塌土砂災害。本文從現地地質調查、致災機制、水文分析及遙測影像判釋等面向進行討論。由降雨-延時-頻率分析得知近年來誘發重大崩塌事件的雨量皆高於200 年回歸週期，並獲致良好判別致災雨場之I-R 圖降雨臨界線關係(Re+53.5Iave=1,146)。多時期遙測影像判釋指出東澳嶺坡頂之弧型張力裂隙仍有持續溯源發展之趨勢。裸露崩塌地不連續面方位密度分布圖之裂隙位態大致與區域地質構造位態 (N70°W) 相近，顯示本區域崩塌主要仍受地質條件主控。此外，蝕溝溯源侵蝕、剪裂帶分布及凹漥坡型亦為影響研究區崩塌地地貌變遷之重要因子，而前期地震或長延時高強度降雨則為外在促崩因子。Typhoon Megi coupled with the northeastern monsoon induced an extreme rainfall of 939 mm on the Suao area, Yilan County, in eastern Taiwan on October 21st, 2010, causing the Dong-Ao Peak landslide of 2.1 million m3 along the coastal Su-Hua Section of Highway Route 9. This study adopts a geological survey, rainfall data, satellite images, orthophotos, and high-resolution DEM based on airborne laser scanner surveys to quantify the morphological changes before and after landslide events following major rainfall events since 2010. Rainfall frequency analysis indicates the cumulative precipitation triggering landslide events is greater than the 200-year return period. In addition, both the entrainment effect of debris flow and toe erosion on the down-slope is shown to induce regressive sliding failure at the adjacent roadbed. The results suggest that geological factors such as head-cutting erosion and the concave landform shape the landform evolution of the catchment. The occurrence of landslides also depends on antecedent earthquake events and extreme intense rainfalls

个体创造力对创业意向的影响:以新生代员工为例

创新是推动国家经济发展和社会进步的重要力量,新生代员工作为组织内的主力,是大众创业、万众创新的重要组成部分。提升新生代员工创业意向,推进新生代员工创业活动的开展,有必要探索影响新生代员工创业意向的具体因素。以社会认知理论为基础,以创业自我效能感为中介变量,以创业环境为调节变量,构建个体创造力对创业意向的影响模型。对长三角、珠三角以及福建地区352名新生代员工进行问卷调查,结果表明:新生代员工创造力对其创业意向存在显著正向影响;创业自我效能感在创造力与创业意向之间起部分中介作用;创业环境中的市场资源环境调节创造力与创业意向之间的关系,并且市场资源环境与创造力之间的交互项通过创业自我效能感间接影响员工创业意向。福建省社会科学规划青年项目(FJ2016C040

台2線 68K 八斗子滾石災害致災成因初探

基隆市北寧路於2013 年8 月31 日下午發生高強度降雨事件 (最高達94.5 mm/hr)，並導致台2 線68K+000 處於當日16 時19 分左右發生落石擊毀小客車之意外。本次落石災害之發生區屬於大寮層中段塊狀砂岩，且為逆向坡之型態，現地調查結果顯示本區域具有兩組傾角近乎垂直之節理面，一組走向約略平行於海岸線，另一組走向則約略垂直於海岸線。致災成因可能與長期雨水入滲及風化作用有關，節理裂隙除因風化作用逐漸加大外，節理面上之含鐵質結核亦可能於風化後體積增加，進而加速節理開裂速度。本次落石災害之運動歷程大致可分為傾倒、滾動、墜落、彈跳、滾動等數段歷程，落石運動過程耗時約23 秒，移動路徑上之植被與風化土壤層可能為遲滯落石運動之主因。本文將說明此次災害之地質調查成果，並探討可能之破壞機制，以供未來類似災害之防治對策參考。Several rockfalls caused damages on Highway No.2 during an intensive rainfall on August 31, 2013, in Keelung. One of the rockfalls hit a car and the event was captured by a camera. This study analyzes the mechanism of the rockfall based on the video and field investigation. Two major joints which led to the hazard, one was parallel to the coast and the other was perpendicular to the coast. Both of them were almost vertical and cut the rock into several blocks. Weathering processes may have lead to the extension of joints during the heavy rainfall; the infiltration and the surface runoff took the weathered material away, making the rock unable and ultimately leading to the rockfall. The process of this hazard can be divided into topple, roll, fall, bounce and roll. The rockfall took about 23 seconds in total. This paper focuses on the results of field investigation and the mechanism of the rockfall is also discussed
