來台陸生「社會接觸」對「社會距離」與「政治社會化」影響之研究 / The Social and Political Contagion of Chinese Students Studying in Taiwan

沈湘湘, Shen, Hsiang Hsiang Unknown Date (has links)
兩岸關係研究在開放政策的導引下,自過去以共黨體制與理論研究,轉為更務實的經濟和文化研究,兩岸社會和人民透過頻繁交流瞭解彼此,是目前兩岸關係的重要發展,其中一項趨勢即是大陸年輕學生能在台灣停留,並在一段不算短的時間內深入一般民間生活,這些所謂的「陸生」在來台停留4個月以上的時間內,除了在學校上課,騎單車環島、搭「台灣好行」、搭台鐵、坐公車等等方式,在台灣城市和鄉野間體驗與感受,一部分人更在選舉造勢場合,和激動的選民一起喊凍蒜凍蒜。 根據Allport以來學者對於接觸相關研究文獻的瞭解,群際之間的研究必須考慮接觸的內涵、接觸的過程以及制約接觸的條件等對接觸效果的影響。傳統「接觸假說」認為類似文化背景之群體可透過深度交流接觸達到真正理解溝通,消除群際偏見與隔閡,達到族群融合。 本論文即以上述理論為基礎探討兩岸年輕學子交流的樣態及效,透過量化的問卷與深度訪談,探索這個族群接觸內涵與過程,理解到所謂的「接觸」並不能僅限於「接觸的頻率和時間長短」,也不能僅奠基在語言文化具類似性的基礎上,就達到「接觸假說」所預設的「消除類屬」(de-categorization)或進一步「融合類屬」(re-categorization)。因為族群之間各成員心中存在著「自我類屬」(self-categorization),想要消融彼此的界線,必須先探索成員對自我類屬的定義,此外還須考慮接觸環境上制度面的制約,從制度面的設計增加群際成員的接觸頻率,才能進一步減少成員的「群際偏見」(intergroup bias)及增進「群際情感」(intergroup emotion)。 / In the leading of open policy, the mainstream of cross-strait studies has shifted from Socialism and Communism to Economy and Culture. At the tide of exchange, Chinese exchange students studying in Taiwan are the most propriate targets to learn about, less sensitive and having deep contact with Taiwan society. According to the related studies like Allport’s, scholars should take the content, process, and constrait of contact into consideration while studying the relations between nation groups. Traditional “contact assumption” assumes groups sharing similar culture background will reach mutually understand through exchange in depth, deliminate bias and barriers between groups. This study has examed the impact of the frequency and time length, the language and culture similarity on contact, knowing that those conditions above are not the only factors to de-categorization or further re-categorization. The members of each group have bared self-categorization in mind. Eliminating intergroup bias and enhance intergroup emotion would play an important part of breaking down the walls between groups. Besides, the goal of institutional design is to make the contact more intensive and to avoid the false contact. The less attractions offered by media to the Chinese exchange students, the less political socialization they will have. So the policy design should be delicate enough to allow those students to take the advantages of curriculums、professors, and schools to reach the goal of social contact between the young generations of cross-strait.

台灣職業流動模式及其變遷之研究

張銀旭, ZHANG, YIN-XU Unknown Date (has links)
在一社會中,職業常常被視為個人成就地位的表徵。透過對職業流動的研究,不但可 以瞭解台灣社會階層化的情形,更可以看出台灣社會流動的變遷狀況。本研究嚐試利 用台灣兩個不同時點上的資料,分析台灣地區父子職業流動的事實,期望達成以下的 目的: 1.以父子兩代職業流動的密度為標準,找出流動的模式;並分別檢視不同的時點上 ,有無明顯變遷的事實。 2.以職業類別間之距離為流動障礙的指標,找出不同類別間職業流動的障礙,並加 以比較之。 3.綜述流動模式與流動障礙的關係,並對「台灣社會流動之開放性」問題做一省思 。 本研究分析資料為行政院主計處於民國六十五年及七十五年所做的「家庭收支暨個人 所得分配調查」資料。利用該調查對職業之分類,抽取具有父子兩代特性之樣本,分 別整理成為父子職業流動表。計得可用以分析之樣本數六十五年為二二三九戶,七十 年為二九一二戶。透過對數相乘模型之運作,將流動表中各種不同的效果加以分析。 研究之結果發現:近十年來台灣地區職業傳承的效果並沒有改變。易而之,近十年來 台灣社會流動的變異絕大多數是導因於職業結構的變遷。就整體而言,整個社會職業 之流動是相當開放的。這個結果與Featherman&Hauser(一九七八)對美國社會所做 研究之結果大致上相類似。

以互動性距離理論探討同步遠距教學之學習成效

鍾杰男, Chung, Chieh-Nan Unknown Date (has links)
在遠距教育的研究中,學習成效的探討一直是相當重要的議題,然而過去的研究多僅評估不同傳播媒體的有效性或比較近、遠端學生學習成效的差異,缺乏對於學習成效之發生歷程的探討。本研究根據Moore(1993)所提出之互動性距離理論,探討在同步遠距教學環境下學習成效之發生歷程,研究目的如下:一、對話、結構是否能有效預測互動性距離;二、學習者自主性是否能調節互動性距離與學習成效之間的關係。本研究採問卷調查法,受試來自四所大學修習遠距課程的學生,有效樣本239人。研究結果顯示:一、對話與結構可以有效預測互動性距離;二、互動性距離越低,主、客觀學習成效指標表現越好;三、學習者自主性可以調節互動性距離與主觀學習成效指標之關係(當學習者自主性高時,越低的互動性距離可以預測越高的滿意度),然而,學習者自主性不能調節互動性距離與客觀學習成效指標之關係。 本文最後針對所有研究結果進行討論,並根據研究結果提出可能的限制與未來研究方向的建議。 / The learning performance of distance education has been studied for a long period of time. Most of the past studies just simply compared the effectiveness of different media and teaching styles or the learning performances of students in local and remote site. However, little empirical studies had been found to see the process underlying learning performance. As mentioned above, a framework of the process underlying learning performance in synchronous videoconferencing learning environment based on the theory of transactional distance (More, 1993) was developed in this research.239 subjects from four different universities involved in the current study. The result showed that, first, dialogue and program structure could successfully predict the degree of transactional distance. Second, the smaller the transactional distance was, the better the objective and subjective learning performance was. Third, learner autonomy could moderate the relation between the transactional distance and the subjective learning performance. When students’ learner autonomy were high, the smaller the transactional distance was, the better the subjective performance was. However, learner autonomy couldn’t moderate the relation between the transactional distance and the objective learning performance.

混合連續與間斷資料之馬式距離的穩健估計 / Robust estimation of the Mahalanobis distance for multivariate data mixed with continuous and discrete variables

任嘉珩, Jen , Chia Heng Unknown Date (has links)
本研究採用Lee 和Poon 所提出的隱藏常態變數模型來估計混合連續與間斷型變數之參數估計,並估計其馬式距離。此外,並利用穩健估計來估計混合型資料參數及其馬式距離,可在有離群值時解決最大蓋似估計的不穩定。 / Poon and Lee (1987) applied normal latent variable model to deal with the parameters estimation for the data mixed with continuous and discrete variables and Bedrick et al. (2000) used this idea to evaluate the Mahalanobis distance. In this thesis, we extend a similar idea to robustly estimate Multivariate Data Mixed with Continuous and Discrete Variables with the same model. Furthermore, we evaluate the Mahalanobis distance which can determine similarity of variables. The proposed method can overcome the unreliability of MLE while there exist outliers in the data.

台灣銀行業效率與生產力分析─方向距離函數之應用 / Efficiency and productivity change of Taiwanese banking Industry- An application of directional distance function

范雅鈞, Fan, Ya Jyun Unknown Date (has links)
本文利用可以同時捕捉到銀行增加意欲產出、減少投入與減少非意欲產出的方向距離函數,評估台灣銀行業與個別銀行在民國93年至97年的無效率值與生產力變化。設定逾期放款為銀行生產放款時的非意欲產出,以考量銀行的放款品質,也考慮到銀行都會付出成本來提供服務給存戶,因此以交易性存款作為銀行提供服務的替代變數,使銀行的服務包含在效率評估內,並以固定的方向向量作為無效率值加總的基礎,來衡量台灣整體銀行業的無效率。實證結果是台灣銀行業的無效率值隨著雙卡風暴的遠去,有逐年遞減的趨勢,生產力的變化則是退步的情況較多。 / In this paper we estimate Taiwanese banks’ efficiency and productivity change during 2004-2008. The estimates are derived from the directional distance function. We treat non-performing loans as an undesirable output arising from the production of loans to measure the quality of loans. Considering every bank would make costs to serve customers, we choose transaction deposits as an alternative variable to capture the service provided by banks. The way we set the directional vector allows the aggregation of individual bank inefficiency and productivity change to the industry level. Our findings indicate that inefficiencies of Taiwanese banking industry were decreasing after the over of credit and cash card debts. And Taiwanese banking industry experienced productivity regress during this period.

運用隨機方向距離函數法探討非意欲產出對銀行經營效率之影響 / Do Undesirables Matter on the Examination of Banking Efficiency Using Stochastic Directional Distance Functions

鍾銘泰, Chung, Ming Tai Unknown Date (has links)
本文採取隨機方向距離函數方法,探討制度變革前、後(第一次金融改革)對台灣銀行業技術效率的影響。資料期間涵蓋1999年至2012年。相較傳統Shephard距離函數,隨機方向距離函數方法最大優點係可同時考量增加意欲產出、減少投入與非意欲產出。本文依循Koutsomanoli-Filippaki et al. (2009a) 模型,並納入考慮非意欲產出。本文採取隨機邊界法進行實證估計,以最大概似法估計方向距離函數,依據Battese and Coelli (1995)的模型將環境變數納入實證模型 (主要模型),並考量未包含環境變數之模型,與主要模型比較。此外,為凸顯非意欲產出之重要性,本文亦估計未考慮非意欲產出之模型以及傳統距離函數,以茲比較。 實證結果顯示,考慮非意欲產出與環境變數的主要模型,其估計結果相較其他模型之無效率明顯高估。2002年以前,技術無效率逐漸攀升。一次金改期間,技術無效率明顯下降,證明制度變革下,銀行效率獲得改善。惟2004年後反轉向上,尤其在雙卡風暴與次貸風暴期間,技術無效率明顯惡化。此外,本文將資料分群進行分析,發現公營銀行或是金控銀行較有效率。 / This paper aims to gain further insights into whether the policy of First Financial Restructuring (FFR) does improve the technical efficiency of banks in Taiwan during the period 1999-2012 by using the directional technology distance function (DDF). Compared to the conventional distance function, DDF simultaneously allows for the expansion of the desirables and the contraction of the undesirables. We follow Koutsomanoli-Filippaki et al. (2009a), and differing from them, we include undesirable outputs in DDF to depict a bank’s true production activities. We find on average that the banks have a lower technical inefficiency with the main model compared to the other models. However, prior to 2002, the technical inefficiency exhibits a gradual upward trend and then posts a downward trend during the FFR period. These results suggest that the improved efficiency in the FFR period is possibly due to enhanced banking and benefits obtained from compliance with FFR. After the FFR period, the inefficiency scores deteriorate sharply, especially during the “credit card and cash card crisis” in 2006 and “the subprime mortgage crisis” in 2008. Public banks are more efficient than private banks. Banks belonging to a financial holding company (FHC) may operate more efficiently than those belonging to a non-FHC.

人口流動模型的距離效應之探討 / A distance-based modification of spatial interaction model in modelling population movement

梁穎誼, Leong, Yin Yee Unknown Date (has links)
人口流動具有各種型態。其中包含了遷移、移動、以及通勤人口。在宏觀模型框架下,空間互動模型(簡稱SIM)對於測量人口流動扮演了重要的角色。距離遞減效應為空間互動模型中重要的因子。該效應描述了人口流動的頻率會隨著移動距離而逐漸下降。然而,從實證上,本研究發現人口流動與移動距離的函數,並非在距離上保有恆定的關係。 在本文中,我們提出了對此非恆定的距離遞減效應之修正方法。本修正法運用了轉折點模型的特點,套入了空間互動模型的距離函數上。本文首先運用了電腦模擬驗證了此方法的穩定性與有效性。接下來,研究將此方法應用在兩個人口流動資料。第一個是從台灣健保資料庫觀察出的民眾就醫地變化。健保資料庫包含了總人口的5%抽樣資料。由於在抽樣上瑕疵不大,因此健保抽樣資料具有了一定的代表性。第二個資料則是英國統計局所提供的人口遷移普查資料。在這兩個資料上,我們發現本研究所提修正法,相較於傳統的空間互動模型具有更好的模型配適表現。此改善程度在非都市地區尤其更為明顯。 / Population movement encompasses various forms, such as migration, mobility, and commuting. Spatial Interaction Model (SIM) serves as an important tool to calibrate these movements in the sense of macro modelling. One of the important features of this model is that the number of migrants often decays with the distance. However, we found that this is not always the case in practice and the decay pattern may change with distance. In this study, we propose a distanced-based modification to the SIM, via applying the techniques of change-point problem to construct distance functional form. Computer simulation is illustrated to validate the method and the empirical analysis of flow data from Taiwan’s National Health Insurance Research Database (NHIRD), and also England & Wales internal migration data also provides sound evidences to support the proposed approach. Note that the flow data from the NHIRD consists of a sample of about one million people and can be treated as a fine sample representative of Taiwan’s whole population (about 23 million people). Our results show that the modified approach is more adequate than the traditional SIM, especially for describing the movements of suburban areas in Taiwan.
