The effect of internal liquidity on performance of structural models
No full text在信用風險領域裡，學者試圖找出更多可以改善結構型信用模型績效的因子。因此，有別於其他的結構型模型實證文獻，本文的重點在於探討公司內部流動性對於結構型模型在債券價格評價誤差上的影響。由實證結果發現，內部流動性的確對於部分結構性模型的評價績效有益。Researchers have been trying to introduce more relevant credit risk elements to improve the performance of structural models. Distinguished from other literature, we focus on the explaining power of a firm’s internal liquidity on the prediction errors of structural models. Our results show that the cash flow volatility do have a significant explaining power for the prediction errors of some structure credit models.口試委員審定書 i

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
Preferences for end-of-life care and decision-making among Chinese community-dwelling older adults: A comparative cross-sectional study in Hong Kong and Wuhan in China
No full textThis study aimed to describe and compare end-of-life care and decision-making preferences among Chinese community-dwelling older adults between Wuhan and Hong Kong in China. The study adopted a cross-sectional correlation design and recruited a convenience sample of 259 older adults, aged ≥65 years old from five community centers in Wuhan and Hong Kong. Participants completed a validated structured questionnaire that measured their end-of-life care and decision-making preferences. Multivariate logistic regression analyses were conducted. Results showed that Wuhan participants were significantly more likely to view “trying every means to extend the life span” as very important/important; and they perceived “support from religious personnel” as unimportant/very unimportant. Different from those older adults in Hong Kong, the Wuhan participants significantly chose their home as the preferred place for end-of-life care and death. They also tended to prefer family members to enact the decision-maker role in end-of-life decision situations. The study suggests older adults in Hong Kong and Wuhan have some differences in preferences for end-of-life care and decision-making, which provides the basis for future development of culturally relevant community-based end-of-life care
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
