The Study on Cao Rui
Full text link曹叡是曹魏的第二位皇帝，与其祖曹操、其父曹丕并称为“魏之三祖”。其声名虽不如“三曹”显赫，但如全面加以考察，其于政治、文学层面皆有独特贡献。今人研究多偏于政治层面，文学史著作对曹叡大多略而不提，偶有提及，也只是寥寥数语。本文试图理清其生平中的一些疑点和模糊之处，深入探究其人的性格特征，阐述其思想理念，并在此其础上对曹叡作品尤其是诗歌创作进行分析考察和总体评价。 主要内容有： 第一章考察曹叡生平。结合史料对其生年、辞世年龄、久不得立为太子之故、立嗣与辅政大臣改易风波等生平中模糊之处进行考察梳理。 第二章探讨曹叡的个性与思想。在对史料比对分析的基础上论述曹叡的性格特征。分析其思想理念，即以“...Cao Rui is the second emperor of the Wei Kingdom，and he is regard as one of“The Three Generations of The Wei Kingdom”.Although the reputation of Cao Rui is not prominent than “Three Caos”，he also has unique contribution to politics and literature in the case of a comprehensive study. Modern people tend to research the political level，and the literary history works say nothing about Cao Rui mostly，...学位：文学硕士院系专业：人文学院中文系_中国古代文学学号：1022006115005
Knowing the price of success
No full textIf an agent, or a coalition of agents, knows that it has a strategy to achieve a certain outcome, it does not mean that the agent knows what the strategy is. Even if the agent knows what the strategy is, she might not know the price of executing this strategy.The article considers modality “the coalition not only knows the strategy, but also knows an upper bound on the price of executing the strategy”. The main technical result is a sound and complete bimodal logical system that describes the interplay between this modality and the distributed knowledge modality.<br/
The limits of morality in strategic games
No full textAn agent, or a coalition of agents, is blameable for an outcome if she had a strategy to prevent it. In this paper we introduce a notion of limited blameworthiness, with a constraint on the amount of sacrifice required to prevent the outcome. The main technical contribution is a sound and complete logical system for reasoning about limited blameworthiness in the strategic game setting
Budget-Constrained Dynamics in Multiagent Systems
Full text linkThe paper introduces a notion of a budget-constrained multiagent transition system that associates two financial parameters with each transition: a pre-transition minimal budget requirement and a post-transition profit. The paper proposes a new modal language for reasoning about such a system. The language uses a modality labeled by agent as well as by budget and profit constraints.
The main technical result is a sound and complete logical system that describes all universal properties of this modality. Among these properties is a form of Transitivity axiom that captures the interplay between the budget and profit constraints
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
