When to Put All Your Eggs in One Basket.....When Diversification Increases Portfolio Risk!
Get PDFPortfolio diversification may not always lower the portfolio risk, but may actually increase it. It depends on the long memory and distributional stability characteristics of the underlying rates of return. This disturbing result is based on the theoretical Fama- Samuelson proposition of 1965-67. However, there exists now ample empirical evidence for such peculiar results, since most financial return series show long memory, e.g., the S&P500 Index return series. Illiquid real estate and bank loan values are sometimes subject to catastrophic discontinuities. Adding these assets to the portfolio may increase its risk drastically.portfolio management, distibutional stability, long memory, financial risk,
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
Censorship in World War I: the Action of Wilson's Committee on Public Information
No full text"The Committee on Public Information was created by Woodrow Wilson during World War I as a government instrument for the management of public opinion during wartime. Headed by George Creel, the CPI quickly dominated two key and interwined aspects of mass communications: censorship and propaganda. Praised as "a nationalizing force at home and an Americanizing agent abroad", the Committee's overall goal was to promote the circulation of positive images of the United States and counter or prevent the spread of negative perceptions of the USA or of Great Britain and other Allied Powers. Daniela Rossini sees in the CPI's activities "a crusading attitude and a skillful combination of selective repression, centralization of information, control of the media and propaganda", that enabled Wilson's administration to manage public opinion in an unparalleled way. Censorship was not simply imposed by the government. The press, the film industry, other mass media, and the general public were urged, for the sake of honor and patriotism, to comply with CPI guidelines. In other words, the government sought to mobilize a general "self-imposed conformism" in order to achieve what amounted to high level of voluntary censorship. The CPI also undertook missions abroad. Charles Merriam led one such mission to Italy, organizing the first mass propaganda campaign in favor of he United States in that country, and offering a plan to improve Italian propaganda in the United States. Noting John Dewey's observation on the efficacy of mass methods in manufacturing popular sentiment for all kinds of causes (worth or not), this essay argues that the fabrication of consent was in fact achieved by repression of democratic rights. Daniela Rossini is careful to point out that U.S. censorship and propaganda were not so heavy handed as they were at that time in Italy, France or other European countries, but she echos arguments similar to those used by Alex Goodall regarding the contradictory nature of Wilsonian policies and their adverse effects on the functioning of democracy in the United States. The capacity of government-inspired censorship and propaganda to fabricate majority consent was proven by the CPI and the reactions of USAmerican society during World War I. This experience undermined basic U.S. assumptions about enlightened public opinion. It shed doubts on the capacity and willingness of an intelligent general public to maintain independent and diverse rational opinions. Furthermore, the author argues, it created a social atmosphere which was unfavorable to the expression of dissent, while sowing the seeds of reactionary postwar hysteria which encouraged antidemocratic attitudes of "isolationism, illiberalism and intollerance"."

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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
