評審間意見一致程度之問題探討 / The Problems of Interater Agreement

楊麗華, Yang, Li-Hua Unknown Date (has links)
本文主要在探討評審間意見一致程度的問題, 除了回顧kappa係數和weighted kappa係數及其應用外. 並討論如何採用對數線性模型中加入代表一致程度的參數來分析這類的問題. kappa係數提供應用者一個快速獲得評審間意見一致程度的指標, 而利用對數線性模型分析, 則可以獲得更多的訊息. 因此, 我們嘗試將kappa係數和對數線性模型作一對比. 此外,針對三個評審間意見一致程度的問題我們也引進K-ABC係數, 並與模型log(m-ijk) = u + l(A, i) + l(B, j) +l(C, k) + Delta*I(i=j=k) 作以對比, 利用模擬實驗將Delta(hat)與K(ABC)所對應的可能範圍列出, 供使用者參考. / The focus of this study is on the measurement of interater agreement. Analyses in terms of kappa tyoe coefficients and in terms of loglinearmodel techniques are reviewed, and issues related to the two approaches adderssed. In additition, a new kappa type corfficient Kappa-ABC is introduceto provide indication of agreement among three raters. Its possible connections with the coefficient Delta in the model log(m-ijk) = u + l(A, i) + l(B, j) + j(C, k) + Delta*I (i=j=k) are studied.

台灣地區社會犯罪住戶面受侵害者模式之研究 / Study in the Social Criminal Victimization's Model on Housing Unit in Taiwan

謝志偉, Hsiesh, Jyh Woei Unknown Date (has links)
傳統的犯罪學在於研究犯罪者生理與心理的特性以及外在環境因素,藉以 尋求預防犯罪的策略。其實,預防犯罪的目的是要減少被害者數目。因此 ,吾人希望藉由探討被害者家庭形態的特質與社會犯罪的關係,使防範被 害的政策能夠落實到家庭層面。所以本研究的目的就是要利用統計方法, 透過數字及圖形上的表達,來描述住戶之家計負責人的特性(如性別、年 齡、教育程度)與住戶遭受侵害的事實(曾或否)及類型(如財物侵害、暴力 侵害、其他侵害)之間的關係,期為犯罪統計工作提供一些分析的工具。 在本篇論文,首先利用對數線性模式分析,選出最適合的模式,以解釋家 計負責人之性別、年齡、教育程度與住戶是否遭受侵害等四個變數之間的 關聯性。接著利用推理值模式分析探討家計負責人之性別,年齡,教育程 度這三個解釋變數各分級對住戶遭受侵害之影響的主效應及交互作用效應 。最後則是利用對應分析處理資料,透過對應分析的顯示圖形,可以用來 解釋家計負責人之性別、年齡、教育程度以及住戶遭受侵害的犯罪類型之 間的對應關係。

國際學生來臺趨勢、擇國擇校過程及滿意度之研究 / Tendency, decision-making processes, and satisfaction of international students in Taiwan

張琦, Chang, Chi Unknown Date (has links)
近來,臺灣教育部為招收更多國際學生而實行新政策。本研究分析政策實行的效果、學生來臺原因及在臺學生的滿意度。研究一以時間序列分析1954至2008年的國際學生人數,ARIMA模式的預測效果良好(RER=0.83%),未來三年內國際學生人數將突破二萬人。研究二以問卷調查分析學生選擇留學國家及學校的選擇因素,同時分析學生來臺動機、所遇困難及在臺滿意度間的關係 (N=210)。結果顯示容易的簽證程序及臺灣的學術聲望影響學生來臺讀書;此外,財務、後勤及生活條件影響學生選擇留學學校。學生因臺學術聲望來臺且無食物適應困難者,願意再次來臺念書;學生因具吸引力課程及方便生活環境來臺且無硬體設備及學習適應方面困難者,願意建議他人來臺留學。根據研究結果,政府應加強國內教學品質,並協助提升學校學術聲望;增加赴海外任教教師,以教學專業提升我國國際形象。有興趣吸引國際學生的學校應可從健全學校行政體制著手,並聚焦於完善學生招生、入學諮詢輔導工作及協助生活適應。 / Recently, the Taiwanese Ministry of Education has implemented a new policy to recruit more international students. This study analyzes the policy’s effects and the reasons motivating students to study in Taiwan. The number of international students in Taiwan from 1954 to 2008 was used to generate a time series model to estimate the number of international students before and after the policy implementation. This ARIMA model (RER=0.83%) demonstrated a dramatic increase in the number of international students over the years. Using a questionnaire designed to examine determinants that affect international students’ decisions for choosing Taiwan and their respective schools (N=210), this study then study the relationship between the students’ motivations, the challenges they faced, and their degree of satisfaction with their experiences. Results demonstrated that an easy visa application process and Taiwan’s acclaimed academic reputation attracted students. Furthermore, financial, logistical, and living reasons affected the students’ choices in schools. Students who found living and educational conditions favorable and who felt intellectually stimulated would choose again to study in Taiwan and would recommend others to do so. Based on these results, the government should strengthen the quality of instruction and further promote Taiwan’s universities abroad. Schools interested in attracting international students should develop structured administrative systems focused on recruiting students and helping them transition into a new environment.
