Mobile Exam System – MES: Architecture for Database Management
No full textAs the mobile applications are constantly facing a rapid development in the recent years especially in the academic environment such as student response system (Lópeza, Royoa, Labordab & Calvoa, 2009; Ngai & Gunasekaran, 2007; Mary & Biju, 2008; Nayak & Erinjeri, 2008; Roth, Ivanchenko & Record, 2008; Lu, Stav & Pain, 2009; Lu, 2009; Turning technologies, 2010) used in universities and other educational institutions; there has not been reported an effective and scalable Database Management System to support fast and reliable data storage and retrieval. This paper presents Database Management Architecture for an Innovative Evaluation System based on Mobile Learning Applications. The need for a relatively stable, independent and extensible data model for faster data storage and retrieval is analyzed and investigated. It concludes by emphasizing further investigation for high throughput so as to support multimedia data such as video clips, images and documents
Estimating value-at-risk for portfolios: skewed-EWMA forecasting via copula
No full textWith the increasing complexity of risks, how to estimate the risk of portfolios with complex dependencies is challenging. Recently, Lu and Huang (2007) proposed a skewed-b WMA procedure to calculate value-at-risk (VaR) for individual financial assets, which is derived from an asymmetric Laplace distribution and takes into account both skewness and heavy tails of the return distribution that are adaptive to the time-varying nature in practice by adjusting shape parameter in the distribution. In this paper, we extend the skewed-EWMA procedure to estimating the risk of complex portfolios with dependencies modelled via copula. Monte Carlo simulation procedure that combines copula techniques with skewed-EWMA forecasting is developed. The empirical backtesting evaluation of the VaR forecasting demonstrates that the proposed method can be a useful tool in estimating extreme risks of some complex portfolios

Weiming Lu was invited to speak in the McDermott Lectureship in 1991 on the University of Dallas Campus. This is a very faint recording.The McDermott Lectureship
In 1974, the university established the Eugene McDermott Lectureship, an endowed lecture series created in honor of Eugene McDermott, the late scientist, businessman, civic leader and philanthropist. It was established on behalf of Mrs. and Mr. Eugene McDermott in 1974 to honor Donald and Louise Cowan's vision and leadership at the University of Dallas and in the city. Beginning with the venerable historian Jacques Barzun, the McDermott Lectureship continues to bring notable public intellectuals to the university for short courses and seminars.
Through the McDermott Lectureship, the University of Dallas and the Braniff Graduate School of Liberal Arts host exceptional guest lecturers and distinguished faculty members on thought-provoking topics within the Western tradition. Prominent scholars have spoken on many topics including art, politics, education, science, Christianity, Western thought, urban planning, medicine, technology, collectivism, liberal arts, philosophy, reason, poetry, physics, architecture, Homer, Aristophanes, Aristotle, Plato, Dante, St. Thomas Aquinas, Locke, Tocqueville, and Leo Strauss.University of Dallas, McDermott Lectureshi
The shaping of Lu Xun&amp;apos;s public image and his portrait images
No full textAfter Lu Xun published “A Madman&amp;apos;s Diary” (Kuangren riji) and “The True Story of Ah Q” (A Q zhengzhuan), through the active introduction by modern Korean mass media, Lu Xun enjoyed the highest popularity of all modern Chinese literary author in Korea Peninsula. “A Madman&amp;apos;s Diary” translated by Ryu Sooin, was published in the magazine Donggwang (The oriental light) in 1927. Yang Baekhwa&amp;apos;s translation of “The True Story of Ah Q” was serialized in The Chosun Ilbo (The Korea daily) in 1930. “Lu Xun and His Works” by Jeong Raedong, who conduct systematic criticism on Lu Xun&amp;apos;s literature, was published in The Korea Daily in 1931. Lu Xun was thus differentiated from the so‐called “Zhou Brothers” and claimed a place of his own as a representative Chinese writer. After that, Lu Xun&amp;apos;s various works were translated into Korean, and he was acknowledged as “a Chinese literary master” and “a world‐class writer” in the Korean literary world. Lu Xun&amp;apos;s literature was hence widely acknowledged. Lee Kwangsoo even created another character called “Park Seondal” based on the motif of “Ah Q.” With the development of mass media, people were eager to see Lu Xun&amp;apos;s personal image. In the 1930s, major Korean media, such as The Shin Dong‐a (The new East Asia), The Dong‐a Ilbo (The East Asia daily), The Chosun Ilbo (The Korea daily), The Maeil Sinbo (The daily report), Chokwang (The morning light) and Samcheonli (Three thousand miles), successively published Lu Xun&amp;apos;s portraits and photos, helping visualize Lu Xun&amp;apos;s image and making great contributions to shaping the public image of Lu Xun and his literature. Through these major media in Korea, Lu Xun&amp;apos;s works and his reputation became widely known, and his portrait images were also circulated. In February 1938, the Hwarang Garden Troupe staged the play The True Story of Ah Q. Considering the commercial nature of the theatre at that time, the public performance of The True Story of Ah Q indicates that Lu Xun and his works had achieved a solid foothold in the public mind. However, Korean people&amp;apos;s access to Lu Xun&amp;apos;s literature was blocked after March 1938, when Japanese imperialists imposed a blanket ideological clampdown. With the advent of liberation on August 15, 1945, the modern Korean public strongly needed Lu Xun&amp;apos;s life experience and literary spirit as enlightenment. Hence, translation and research of Lu Xun&amp;apos;s literary works became active again. In particular, in 1946, after the publication of The Collected Short Stories of Lu Xun (Volumes 1−2), jointly translated by Kim Kwangju and Lee Yongkyu, which included Lu Xun&amp;apos;s major works, Korean people were able to gain a more systematic access to Lu Xun&amp;apos;s literature. The inspirational value of Lu Xun&amp;apos;s literature was re‐ignited after Korea&amp;apos;s liberation and independence. Lu Xun was thus once again praised as “a literary giant” and “a great writer. © 2020 Brill Academic Publishers. All rights reserved
