On the relationships among queue lengths at arrival, departure, and random epochs in the discrete-time queue with D-BMAP arrivals
No full textWe consider finite- and infinite-capacity queues with discrete-time batch Markovian arrival processes (D-BMAP) under the assumption of the Late Arrival System with Delayed Access as well as the Early Arrival System. Using simple arguments such as the balance equation, "rate in=rate out", we derive relationships among the stationary queue lengths at arrival, at departure, and at random epochs. Such relationships hold for a broad class of discrete-time queues with D-BMAP arrivals. (C) 2001 Elsevier Science B.V. All rights reserved

[[alternative]]Intending Outcast? --North Korean Self-Forming and Separation of the Position of Outcast in N.K.-U.S.-China-Strategic Triangle
No full text[[abstract]]北韓地理位置的特殊性，使其在學術與外交實務領域，常以北韓、美、中的「戰略三角理論」分析三方關係。戰略三角理論中，「孤雛」（outcast）被視為比較各類互動模式之最差情形，而國家作為戰略三角的行動者，往往也對此一地位避之唯恐不及。不過，觀察北韓自金正恩上任以來，採取諸如加速發展核武、頻繁試射彈道導彈等挑釁美、中等周邊國家作為，使其與美、中關係快速惡化，甚促美中開始合作制裁，北韓在與中、美之「戰略三角」中似自願落入「孤雛」。2017年開始，北韓透過改善與俄羅斯、南韓關係打開國際困境，陸續會晤中、美領導人，而原本讓北韓陷入孤雛的核武、洲際導彈轉瞬變成與美、中等各方談判桌上的重要籌碼，加上金正恩對內政權掌握具壟斷性、透過改善南韓關係等逐漸緩和對外政策操作戰略多角等方式，在本文所觀察的2017年底至2019年年中期間，北韓在與美、中之「戰略三角」地位獲得快速回升。[[abstract]]Because of North Korea unique location, both in the academic and reality areas, usually use the strategic triangle theory to analysis the North Korea-U.S.-China's relationship. Strategy triangle theory regards the “outcast” is the worst status in all kinds of model. To be a part of the strategic triangle, states always prevent outcast status. However, since Kim Jongun assume the leader of N.K., he took provocative measures to U.S., China and other nearby countries, such as missile launches, nuclear tests and so on. The relationship with China or U.S. turns bad because of the N.K. provocative behaviors, not only promotes China and U.S. coordinate N.K. sanction, but also brings N.K. to be the “intending”outcast in the strategic triangle. Out of the world expectation, N.K. begins to improve the relationship with Russia, South Korea, U.S., and China. From the end of 2017 to the mid-2019 of this writing, the nuclear weapon which make N.K.to be outcast is being the key chip on the negotiation table, and it status in the strategic triangle promoting

“Even the hardest stone can fracture:” Racialization, Reproductive Control, and the Wake of Slavery in N.K. Jemisin’s The Fifth Season
Full text linkWhen the science fiction and fantasy novel The Fifth Season by N.K. Jemisin won the Hugo Award in 2016, Jemisin became the first Black author to win the prestigious literary science fiction award. A departure from similar novels at the time, The Fifth Season has a strong understanding of systems of oppression and how they are built and upheld. This thesis argues that The Fifth Season by N.K. Jemisin follows the conventions of the neo-slave/meta-slave narrative to explore themes of racialization and reproductive control under enslavement and oppression. I conduct a feminist literary of the novel, focusing on these themes, and ground my analysis firmly in Black feminist thought and the study of Black science fiction. Using authors such as Dorothy E. Roberts and Angela Y. Davis, I explore the ways in which Black women in America had their reproduction controlled for dehumanization and profit, as well as how they resisted such control. Using this historical context to read The Fifth Season, I demonstrate how Jemisin’s neo-/meta-slave narrative incorporates these themes of reproductive control and racialization, using the genre of science fiction to re-discover and re-imagine the personal experiences of enslaved women lost to history
The Cause of the Asian Crisis: Fundamentals of Contagion?
No full text本文的主要目的是檢驗亞洲金融危機是因為基本面惡化或是傳染所引起的。首先我們釐清這兩概念之間的分際，然後分別定義代表基本面及傳染的指標來解釋代表金融危機的指標。實證發現事前實質匯率升值和基本面有惡化傾向（金融體質脆弱及外匯存底偏低）對金融危機有顯著的解釋能力。其中金融體質脆弱指標包括銀行對私人部門放款增加率及銀行外債增加率。而外資流入（包括短期外資流入和外人直接投資）及經常帳等總體變數對金融危機都沒有顯著的解釋能力。接著我們分別使用貿易關聯性和金融關聯性代表傳染的傳遞管理，以及用總體經濟類似性代表純粹傳染。我們發現純粹傳染的跡象不顯著，但是一個的危機可透過各國之間金融往來的管道傳染或「外溢」到其他國家。This paper examines empirically whether the Asian crisis was caused by fundamentals or contagion. We find that overvaluation of exchange rates and deterioration in fundamentals (a fragile financial sector and low foreign reserves) both contributed significantly to the occurrence of the crisis. Capital inflows and current accounts, however, do not have explanatory power. Neither pure contagion, represented by macroeconomic similarity, nor trade linkage is significant, but financial linkage does serve as a contagion channel through which a crisis is transmitted across countries
