No full text作為金融資產證券化之創始發展國家，美國自1970年發行第一件房貸抵押證券後，由於此一金融商品的結構化設計對各方參與機構帶來之效益，因此市場蓬勃發展。然而，擁有龐大金融資產之銀行面對擔任創始機構自證券化市場所能獲得之潛在利益，其相關考量為何，過去研究並無深入的討論。因此本文以兩部分分別探討美國金融控股公司作為創始機構從事資產證券化活動之誘因以及對其風險之影響。
對於銀行而言，過去介於借款者與投資人間之垂直整合經營模式以及以利息收入為主的獲利來源，受到證券化之創新架構與交易安排的巨大衝擊，因此證券化活動的從事與否成為銀行重要的管理決策。本文從資本規範、公司規模、資金流動、證券化效益、資金成本與風險管理六大方向，探討銀行作為創始機構從事證券化活動的決定因素。實證結果發現，從事證券化之創始銀行與未從事此一活動的銀行間存在不同之財務特性，此財務特性包括資本適足率、公司規模、貸款比率、存款比率以及證券化利益。
此外，創始銀行在證券化過程中，因金融資產的出售而移轉經濟資源，然而經濟風險是否伴隨資源而加以移轉，近來已成為管制機構高度關切的問題。為了解創始機構從事資產證券化所產生的風險影響，可由資產結構因資源移轉加以重新配置所能降低之風險，以及創始銀行因提供信用增強功能與道德追索權所產生的風險提升兩方面予以探究，實證結果發現，資產證券化對於創始銀行的總風險與系統風險確有提升之影響。Financial asset securitization in the U.S. has been expanding in tremendous pace since its inception in 1970. The creation of innovative structures of securitization provides banks with a new avenue to operate businesses by breaking the vertically integrated intermediation process into distinct steps. In contrast to their traditional role as intermediaries between borrowers and investors, banks can evaluate which steps in the securitization process they possess the competitive advantage and focus on a limited number of roles. For exploring the originating banks’ behavior on securitization, this study investigates two related issues – determinants and risk implications of securitization activities – by using a sample of U.S. bank holding companies from 2001 to 2004.
First, in view of the current and potential growth of securitization, whether to engage in securitization and on what extent have been becoming the important policy choices faced by banks. A number of key factors are examined for the determinants of banks’ securitization decision. Results from tobit estimations reveal that capital constraints, scale economies, funding and liquidity, and enhanced income drive banks’ use of securitization.
Second, a net risk transfer occurs when a securitization transfers more risk than economic resources. To investigate the impact of securitization on next quarter’s bank risk, this study performs total risk and priced risk tests. Regression results show that both risks are increased after securitization. Thus, risk decreases from diversified asset portfolio are outweighed by risk increases from credit enhancement and moral recourse provided by originating banks. Net risk transfer does not occur even economic resources are transferred off the originators’ books.Abstract

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
