Dialogues Between Two Worlds: Prophecy, Resurrection and the Imagination of the Otherworld
Get PDF[...] It is the aim of this thesis to attempt a comparative study of beliefs about the otherworld in a way that bestows the greatest amount of attention to the historical contexts and developments behind them, and to what holders of such beliefs – rather than observers from another culture or time – thought about them. It was born from the observation that, within Chinese and European beliefs about the otherworld from ancient to early modern times, there were many similarities. But to what extent were they the result of coincidences, generated by divergent historical circumstances? What could be gained from their study? [...
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Chen Dong Yuan and His Study on History of the Imperial Examination System
No full text陈东原是我国近现代著名的教育史学家。在他丰硕的中国教育史研究成果中,不仅对科举考试制度本身作了探讨,对科举的不良影响及其弊端进行了抨击,而且对废除科举考试制度提出了自己深刻的认识,从而使科举考试制度史的研究成为其中国教育史研究中的一个重要方面。Chen Dong Yuan is a famous educational historian in modern China.As reagrd his abundant study accomplishments about the history of Chinese education,he not only refers to the imperial examination system while criticizing its ineffective disadvantages,but also puts forward a profound understanding on the abolishment of the imperial examination system.As a result, the historical study of the imperial examination system is considered as an important aspect in the study of the history of Chinese education.2013年度教育部人文社会科学重点研究基地重点项目“中国科举通史”[13JJD880010
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Estratégias de investimento em economias dinâmicas : aplicação do modelo de avaliação Bakshi Chen Dong em uma amostra de 25 ações
No full textThis dissertation studies the effectiveness of the Bakshi-Chen-Dong (2001) valuation model (BCD) in selecting stocks for investment. The BCD model has a closed-form solution where the firm’s equilibrium stock price is a function of its (1) current net earnings per share, (2) expected growth of earnings, and (3) current interest rates. A stock is deemed mispriced whenever the percentage difference between the model price and the actual market value of the stock is far from zero. The performance of this mispricing measure in picking profitable stocks is compared to three indirect valuation indicators (earnings-to-price, size, and past return momentum) in the case of 25 stocks in the Dow Jones Industrial Average Index of 2022. First, alike Dong (2000), the mispricing measure is shown to be close to zero, and mean-reverting every ten months, allowing for potentially profitable trades. Second, when taken explicitly, exploiting the model mispricing is proven to be the most profitable strategy in picking stocks for investment over a one-month time horizon. Finally, a strategy that combines high momentum stocks with low mispricing showed the best performance among all studied.Esta tese estuda a eficácia do modelo de avaliação (BCD) de Bakshi-Chen-Dong (2001) na seleção de ações para investimento. O modelo BCD fornece uma solução fechada na qual o preço de equilíbrio das ações da empresa é uma função de (1) seu lucro líquido atual por ação, (2) crescimento esperado dos lucros e (3) taxas de juros atuais. Uma ação é considerada mal avaliada sempre que a diferença percentual entre o preço do modelo e o valor real de mercado da ação está longe de zero. O desempenho desta medida de avaliação incorreta na seleção de ações lucrativas é comparado com três indicadores de avaliação indiretos (relação lucro/preço, tamanho e dinâmica de retorno passado) no caso de 25 ações do Dow Jones Industrial Index Average 2022. Primeiro, tal como Dong (2000), a medida de mispricing é próxima de zero e reverte para a média a cada dez meses, permitindo negociações potencialmente lucrativas. Em segundo lugar, quando tomada explicitamente, a exploração da avaliação incorrecta do modelo revela-se a estratégia mais lucrativa para seleccionar acções nas quais investir num horizonte de um mês. Uma estratégia que combina ações de alto momentum com baixo mispricing apresentou o melhor desempenho entre todas as estudadas
