歸因理論在補習班顧客行為上之研究

劉原超, Liu, Yuan-Chao Unknown Date (has links)
研究動機:升大專補習班之興起、成長、大專聯考落榜生對「升學輔導的需要」,實 扮演著重要角色,因此補習班的一切策略及行動方案的擬定均應以重考生的需要為起 點。至於策略及行動方案的有效性及成敗,實繫於補習班管理人對重考生行為了解之 深淺及正確程度。因此本論文動機之一即探索重考生對「上補習班」的主觀看法,俾 供發展行銷策略。動機之二即探索重考生個人差異與聯考失敗歸因之關係,俾供補習 班輔導重考生修正不利歸因,並激發其讀書動機。 研究對象:台北市升大專補習班內重考生。 理論依據:Weiner成就動機歸因理論及Kelly 推斷行為原因原則。 執行設計:以問卷型式進行二段式拙樣調查。 分析設計:採因素分析及相關矩陣法為分析工具。 工具設計:1.歸因量表2.折扣量表3.非共同效果量表4.創造力量表5.工作取向量表6. 陸德內外控量表。

股票群的隨機行走模型與內在結構 - 以1996-1999年美國股票S&P500為例之初步分析 / Random walk model and underlying structure - a primitive study of collections of US stocks over 1996-1999

我們從計算股價的相關矩陣,然後利用隨機矩陣定理的結果,了解到股票市場並非符合隨機過程的預測,進而得知股票對股票之間具有關聯性,然其長時距下股票價格對數報酬的變化會呈現隨機行走的模式,因此我們對其結果提出二種不同的耦合隨機行走模型,試圖闡釋股票市場間的關聯性可融合到耦合隨機行走模型之中,並藉由均方對數報酬(mean square log-return,MSLR)來探討此事情。 最後,為了瞭解關聯性的關係,並利用其來了解股票市場內部結構的特性,因此我們利用股價的相關矩陣來建構最小展開樹進行分析,發現當時間尺度越大其圖形越密集,中心幾乎為「GE」這家公司,因此其股票市場具有一定的判斷指標。 / By means of calculating the correlation matrix of the price of stock and using the results of random matrix theorems,we learned that the stock market does not match the prediction of stochastic processes and the stock-stock is correlated。However,stock’s price log-return changes under long time scale will appear random walk model. Therefore,we propose two kinds of the different coupled random walk model,that try to explain the correlation between the stock markets can be integrated into the coupled random walk model,and using the mean square log-return( MSLR) to investigate this issue。 Finally,to understand the relationship of correlation matrix and by using it to know the characteristics of the underlying structure of the stock market,we use the correlation matrix of the price to construct the minimum spanning tree for analysis。The results showed that when the time scale is greater, the graphics are more intensive,and the center is almost the same company,"GE", indicating that the stock market has a certain judgment index。
