This thesis examines the dynamical behaviour of incorporating NMDA (an excitatory neurotransmitter) for the electrodynamic model of the cerebral cortex. The model used is the mean-field model developed by Steyn-Ross et al. (2005) which describes the behaviour of the cortex in terms of parameters averaged over spatially localised populations. The behaviour of the model is determined by the four control parameters: inhibitory effect li, subcortical drive s, and NMDA neurotransmitter e ect set by an excitatory factor le and the magnesium concentration C. Adopting this model could give a better understanding of the cortex functionality and the anaesthetic mechanism. The model predicts that there are either one or three stationary states available to the cortex. We identify two of these with highly activated state and a quiescent state and focus on the transition between the two. Theoretical stability predictions (eigenvalue analysis) verified by a numerical simulation show that the system is unstable between the two Hopf bifurcations. In addition, in the stable region the steady states remains stable under a small perturbation, while in the unstable region either a transition between states or a limit cycle (oscillation) occurs depending on the position of the steady state.

Examines the acute myocardial uptake of drugs, particularly perindoprilat and enalaprilat in humans. The uptake of these agents is examined, together with the haemodynamic, metabolic and biochemical effects. In particular, the impact of these agents on angiotensin and bradykinin peptides both within the heart and peripherally is described. The acute effects of a range of cardioactive drugs upon the left ventricular force-interval relationship is examined.

1997年7月2日泰國宣布放棄泰銖釘住美元而改採管理浮動匯率制度，乃掀起東南亞國家貨幣貶值的危機﹔同時這些國家股價亦遭滑鐵盧之災。東南亞國家金融風暴（亞洲金融風暴）的面貌是﹕幣值與股價同時大幅下滑。但1980年代末期，台灣股價暴漲與新台幣對美金匯率之升值幾乎是同時間發生的。新台幣升值幅度相當的大，且新台幣升值是漸進的，這予投機者以機會。亞洲金融風暴後，央行力守一美元匯兌新台幣在28.6元的匯率，動用近50億美元，打擊投機客，並同時調降存款準備率，放出1350億元的強力貨幣，予股市一股強力的活水。其目的是守住匯價，亦可使股價止跌。然而，市場的表現不是如此，1997年9月與10月股價卻直直下落。 　　研究期間為1990年1月1日至1999年1月31日止，並分成三子期間，以利比較風暴後兩市場互動關係，資料為發行量加權平均股價指數收盤價及新台幣對美元的銀行間平均收盤即期匯率之日資料；類股指數之研究期間為1997年7月1日至1999年1月31日止。運用GARCH模型進行實證分析，並利用一般化動差估計式(Generalized Method of Moments Estimator; GMM) 來估計所建構的迴歸式，以期達成下列目的﹕ 1. 確認台灣股票市場及外匯市場之互動結構關係。 2. 亞洲金融風暴後，其結構關係變化為何？ 3. 確認亞洲金融風暴後，台灣外匯市場對股票市場之各類股的互動結構 關係。 實証結果為： 1. 亞洲金融風暴前，有匯率對股市的報酬率波動外溢效果，亞洲金融風暴後，此報酬率波動外溢效果較風暴前減少，而其它影響股市的因素（非關匯率因素）反而逐漸增強。 2. 股匯市從單向關係（只有匯市影響股市）演變成雙向互動關係，且股市對匯市影響力增強。 3. 金融保險類、水泥窯製類及造紙類，此三類最不受匯市的影響。 4. 塑膠化工類、營造建材類、食品類及紡織纖維類，此四類受當期匯市報酬率的負影響，亦即新台幣升值，此四類股股價會上漲。而機電類股，則受滯延4期匯市報酬率的負影響。 5. 營造建材類，報酬率波動受到其他因素（非關匯率因素）影響很大。 目錄 第一章 緒論 第一節 研究背景與動機……………………………………… 1 第二節 研究目的……………………………………………… 6 第三節 研究限制……………………………………………… 7 第二章 相關理論探討 第一節 匯率的意義、種類及其影響因素…………………… 8 第二節 匯率變動對股票價格的影響………………………… 11 第三節 效率資本市場理論…………………………………… 14 第三章 相關文獻探討 第一節 國外相關文獻………………………………………… 16 第二節 國內相關文獻………………………………………… 19 第四章 研究方法 第一節 相關模型……………………………………………… 25 第二節 分析程序與方法……………………………………… 27 第五章 資料來源與處理 第一節 資料來源與研究期間………………………………… 34 第二節 資料處理……………………………………………… 34 第三節 基本統計分析………………………………………… 35 第六章 實証結果與分析 第一節 股市與匯市報酬率及報酬率波動外溢效果實証結果 46 第二節 各類股與匯市報酬率及報酬率波動外溢效果實証結果 ………………………………………………………… 72 第七章 結論與建議……………………………………………… 76 參考文獻…………………………………………………………… 108 表次 表5-1 股匯市報酬率之基本檢定統計量……………………… 37 表5-2 1997/7/1至1999/1/31各類股之基本檢定統計量…… 41 表6-1 1990/1/1至1999/1/31外溢效果（使用Pearson 交叉相關檢定）………………………………………… 48 表6-2 1990/1/1至1999/1/31外溢效果（使用GMM估計式）… 53 表6-3 1990/1/1至1994/12/3外溢效果（使用GMM估計式）… 58 表6-4 1995/1/1至1997/6/30外溢效果（使用GMM估計式）… 63 表6-5 1997/7/1至1999/1/31外溢效果（使用GMM估計式）… 68 表6-6 1997/7/1至1999/1/31外溢效果（匯市與金融保險類股 ，使用GMM估計式）……………………………………… 74 表6-7 1997/7/1至1999/1/31外溢效果（匯市與水泥窯製類股 ，使用GMM估計式）……………………………………… 78 表6-8 1997/7/1至1999/1/31外溢效果（匯市與塑膠化工類股 ，使用GMM估計式）……………………………………… 82 表6-9 1997/7/1至1999/1/31外溢效果（匯市與營造建材類股 ，使用GMM估計式）……………………………………… 86 表6-10 1997/7/1至1999/1/31外溢效果（匯市與機電類股 ，使用GMM估計式）……………………………………… 90 表6-11 1997/7/1至1999/1/31外溢效果（匯市與食品類股 ，使用GMM估計式）……………………………………… 94 表6-12 1997/7/1至1999/1/31外溢效果（匯市與造紙類股 ，使用GMM估計式）……………………………………… 98 表6-13 1997/7/1至1999/1/31外溢效果（匯市與紡織纖維類股 ，使用GMM估計式）……………………………………… 102

The brine shrimp, Artemia, was used as an experimental organism to study the effects of ⁶⁰Co gamma irradiation on the reproductive performance of an animal population. The total reproductive ability of the brine shrimp was fractionated into various components and the effects of irradiation on each of these components was then determined by studies of reproductive behavior in individual pair matings. In this study, the components identified were the number of broods produced per pair, the number of nauplii voided per pair, the number of nauplii voided per brood, the survival of nauplii to sexual maturity, the number of mature adults produced per brood, and finally the number of mature adults produced per pair. All component parameters of total reproductive performance were shown to be affected by irradiation. However, the number of broods per pair was shown to be the factor most affected by doses of 1200 rads or less. The final parameter, the number of mature adults produced per pair, is really the measurement of the net reproductive potential of Artemia. The net reproduction was also examined by making counts of the total population contained in three liter population cultures, and contrasted to the results obtained with the pair mating studies. It was demonstrated that the population cultures may be maintained by using only a small part of the reproductive potential exhibited in the pair matings. Therefore, we find that the results of pair matings must necessarily be used to assess the amount that the reproductive potential of Artemia is decreased due to various doses of irradiation. It was determined that for Artemia irradiated at the most sensitive stage, a dose of 2100 rads produced sterility. At less sensitive stages, more than 3000 rads would be required to produce sterility. In a single experiment, Artemia irradiated with 300 rads gave an indication of a slight enhancement of reproductive ability as compared to the control animals. In all cases, doses of 600 rads or less showed little effect on the reproductive ability of this species. / Graduation date: 1968
