Asset-backed securities
No full textThis chapter investigates the mechanics of the process of origination, the benefits to investors, and the sources of relative value of asset-backed securities (ABS). After providing an overview of why and how pools of unencumbered assets (often, loans) may be pooled into special legal entities (such as trusts) that are isolated from the potential bankruptcy proceedings that may involve the issuer of the asset, we proceed to explore the cash flow structure that are typical of securitization as it applies to ABS. Special attention is given to the role played by the rating process in determining the value of ABS and hence to credit enhancement mechanisms and the typical rules of allocation of default losses. The second part of the chapter is devoted to a detailed analysis of the key economic features of the most important categories of ABS, namely, auto loan, credit card, student loan, and residential ABS
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
Venture Capital
No full textMany entrepreneurial businesses require substantial capital in the startup phase. The period needed until a firm can bring its products to the market and generate revenues can take years, particularly in high-tech sectors involving scientific research and a complex development process. Often the founders do not have sufficient resources to finance the startup phase on their own. Thus, they need external financing, which, by nature, is mostly equity capital. Because startup firms face uncertain future prospects and lack a strong track record, they are unlikely to receive debt financing. Thus, venture capitalists are investors specialized in funding young businesses. They help close the gap when conventional financing is inapplicable. This chapter provides an overview of the venture capital market, the financial economies of venture capital, and the special features of venture investing
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
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
