National Imagination in “Xun Yu Yan Jiu”(1959-2002)
No full text[[abstract]]On May 20, 1949, the KMT government enforced martial law for a long time in order to pave the way for moving the capital to Taiwan. With 228 incident and the following martial law period, Taiwanese society entered a silence era immediately. Because of the painful experience in Mainland China, the KMT government sternly implemented the restriction and transformation of peoples’ thoughts and speech in order to consolidate it’s regime. During this period, only the speech statement that only conformed with authoritative ideology could be allowed.
This text wants to analyze “Xun Yu Yan Jiu”(1959-2002), to observe it’s national conception and the interaction with KMT government. The result shows that the Chinese nation is constructed by blood relationship and Confucian culture. National hero, leader appearance description, memorial days and PPC description are the methods.
After 1970’s, the counterforce was getting up gradually, but “Xun Yu Yan Jiu” didn’t reflect the changes immediately. It continued the similar viewpoints and tried to collect “Xiang Tu” to Chinese nation. 1980’s, the counterforce became powerful, “Xun Yu Yan Jiu” fought back. After abolishing the martial law, “Xun Yu Yan Jiu” didn’t depart from KMT government and condemned social phenomenon continuously. After 1990’s, “Xun YU Yan Jiu” departed from KMT government and became a professional educational magazine.
“Xun Yu Yan Jiu” appeared with an academic organization, about 40 years, it reflected official ideologies. Its statement of Chinese nation continued almost 40 years and vanished gradually during 1990’s. “Xun Yu Yan Jiu” concerned with educational topic and became a professional magazine and continued to this day.
A question of loyalty : Xun Yu, Cao Cao and Sima Guang
Full text linkIn 212 AD, as the army of the great warlord Cao Cao 曹操 was moving south against his southern rival Sun Quan 孫權, there was a sad incident in the camp. Xun Yu 荀彧, a leading counsellor and one of Cao Cao's oldest supporters, died at Shouchun 壽春 city on the Huai 淮 River. There are varying accounts and opinions whether he died of natural causes or whether he killed himself, but Cao Cao was embarrassed and Emperor Xian of Han 漢獻帝, though close-held under his control, made a point of mourning Xun Yu. Nine hundred years later, moreover, as Sima Guang 司馬光 of the Northern Song dynasty compiled his chronicle Zizhi tongjian 資治通鑑, he took the death of Xun Yu as the occasion for a powerful essay on proper conduct in troubled times. The story of Xun Yu and Cao Cao, therefore, not only touches the tensions of loyalty and legitimacy between a falling dynasty and a rising power, it provided one of China's greatest Confucianists with a case-study for his moral teaching.

Matrix methods in production planning of failure prone manufacturing systems
No full textThis paper studies optimal hedging policy for a failure prone one-machine system. The machine produces one type of product and its demand has batch arrival. The inter-arrival time of the demand, up time of the machine and processing time for one unit of product are exponentially distributed. When the machine is down, it is subject to a sequence of l repairing phases. In each phase, the repair time is exponentially distributed. The machine states and the inventory levels are modeled as Markov processes and an efficient algorithm is presented to solve the steady state probability distribution. The average running cost for the system can be written in terms of the steady state distribution. The optimal hedging point can then be obtained by varying different values of hedging point
Circulant approximation for preconditioning in stochastic automata networks
No full textStochastic Automata Networks (SANs) are widely used in modeling practical systems such as queueing systems, communication systems, and manufacturing systems. For the performance analysis purposes, one needs to calculate the steady-state distributions of SANs. Usually, the steady-state distributions have no close form solutions and cannot be obtained efficiently by direct methods such as LU decomposition due to the huge size of the generator matrices. An efficient numerical method should make use of the tensor structure of SANs' generator matrices. The generalized Conjugate Gradient (CG) methods are possible choices though their convergence rates are slow in general. To speed up the convergence rate, preconditioned CG methods are considered in this paper. In particular, circulant based preconditioners for the SANs are constructed. The preconditioners presented in this paper are easy to construct and can be inverted efficiently. Numerical examples of practical SANs are also given to illustrate the fast convergence rate of the method

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Circulant preconditioners for Markov-modulated Poisson processes and their applications to manufacturing systems
Full text linkThe Markov-modulated Poisson process (MMPP) is a generalization of the Poisson process and is commonly used in modeling the input process of communication systems such as data traffic systems and ATM networks. In this paper, we give fast algorithms for solving queueing systems and manufacturing systems with MMPP inputs. We consider queueing systems where the input of the queues is a superposition of the MMPP which is still an MMPP. The generator matrices of these processes are tridiagonal block matrices with each diagonal block being a sum of tensor products of matrices. We are interested in finding the steady state probability distributions of these processes which are the normalized null vectors of their generator matrices. Classical iterative methods, such as the block Gauss--Seidel method, are usually employed to solve for the steady state probability distributions. They are easy to implement, but their convergence rates are slow in general. The number of iterations required for convergence increases like O(m), where m is the size of the waiting spaces in the queues. Here, we propose to use the preconditioned conjugate gradient method. We construct our preconditioners by taking circulant approximations of the tensor blocks of the generator matrices. We show that the number of iterations required for convergence increases at most like O(\log_2 m) for large m. Numerical results are given to illustrate the fast convergence.As an application, we apply the MMPP to model unreliable manufacturing systems. The production process consists of multiple parallel machines which produce one type of product. Each machine has exponentially distributed up time, down time, and processing time for one unit of product. The interarrival of a demand is exponentially distributed and finite backlog is allowed. We consider hedging point policy as the production control. The average running cost of the system can be written in terms of the steady state probability distribution. Our numerical algorithm developed for the queueing systems can be applied to obtain the steady state distribution for the system and hence the optimal hedging point. Furthermore, our method can be generalized to handle the case when the machines have a more general type of repairing process distribution such as the Erlangian distribution
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
