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
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
Systemic risk in interbank markets
Get PDFDas Ziel der vorliegenden Dissertation ist es, ein besseres Verständnis von systemischen Risiken auf Interbankenmärkten zu entwickeln. Die Bedeutung systemischer Risiken für die Stabilität des gesamten Finanzsystems ist durch die internationale Finanzkrise der Jahre 2007/2008 deutlich geworden, die zu einer der schwersten Rezessionen der letzten Einhundert Jahre geführt hat. Ausgehend von einer Krise auf dem US-Immobilienmarkt kam es in Folge der zunehmenden Verflechtungen zwischen Finanzinstituten zu enormen Verwerfungen auf den internationalen Kapitalmärkten. Diese erreichten ihren Höhepunkt mit dem Zusammenbruch der US Investmentbank Lehman Brothers im September 2008 und führten in den darauffolgenden Tagen zu einem beinahe vollständigen Zusammenbruch der Interbanken-Kreditmärkte. Banken sind auf diese gegenseitigen Kredite angewiesen um kurzfristig auftretende Liquiditätsschwankungen auf der Passivseite ihrer Bilanzen auszugleichen und die Aktivseite ausreichend zu diversifizieren. Ohne funktionierende Interbankenmärkte können Banken keine Fristentransformation vornehmen und die Realwirtschaft nicht mit langfristigen Krediten versorgen. Die Folge eines solchen Zusammenbruchs ist ein Rückgang der
Investitions- und Produktionstätigkeit, reduzierte Handelsaktivität und steigende Arbeitslosigkeit. Um die Stabilität des Finanzsystems zu gewährleisten waren Regierungen und Zentralbanken weltweit gezwungen auf noch nie dagewesene Sondermaßnahmen zurückzugreifen, von denen viele bis heute bestehen. Im Jahr 2009 hat der Internationale Währungsfonds die Gesamtkosten der Finanzkrise mit US$ 11.9 Tril-188lionen beziffert, worin die Kosten für die Notmaßnahmen zur Rekapitalisierung von in Schieflage geratenen Finanzinstituten eingerechnet ist. Die Notmaßnahmen die in vielen Ländern notwendig waren um die nationalen Bankensysteme zu stabilisieren hatten erhebliche Auswirkungen auf die Haushalts- und Schuldensituation der einzelnen Länder. In der schlimmsten Phase der Krise (2007-2009) sind die öffentlichen Schulden der industrialisierten G20-Länder um etwa 20 Prozentpunkte angestiegen. Etwa 5.5 Prozentpunkte dieser Neuverschuldung stammen direkt aus den Stabilisierungsmaßnahmen für den Finanzsektor. Weitere 2 Prozentpunkte stammen aus Konjunkturpaketen welche die direkten Krisenfolgen abmildern sollten. Aus diesen Zahlen wird die Bedeutung des Themas der vorliegenden Arbeit deutlich
The shadow banking system: an analysis of FSB proposed regulation on money market funds in respect to financial stability
Get PDFThe system of non-bank financial intermediaries (NBFI; i.e., shadow banks) has grown rapidly in recent decades up to a roughly size of about Dollar 71 trillion. Shadow banks moved for a number of reasons into the focus of regulatory authorities: (1) the risks associated with circumventing existing rules and the accumulation of high levels of debt, (2) the growing size of the shadow banking system and its associated impact on the real economy and (3) risk stemming from the interconnection and interdependency of banks and shadow banks. The shadow banking system should be considered to be a part of a banking system that evolved out of the traditional banking system, and which combines traditional and innovative banking. The shadow banking system comprises institutions, such as finance companies; several managed funds; a complex array of instruments, such as Asset Backed Securities and repurchase agreements; and structures and markets that replicate core banking activities. Overall, a complex chain of multiple relations between a numbers of institutions has evolved. Each of these institutions performs a different part of the intermediation process. Therefore, it is important to understand the nexus within the shadow banking sector and connections with the traditional banking sector. This work will examine specific institutions involved in the shadow banking system and their development. Further, the scenario of a modern-type bank run within the MMF sector will identify potential weak points of the shadow banking system that should be addressed by financial regulation. The FSB was tasked to develop, in collaboration with other standard setting bodies, a policy framework to monitor and supervise shadow banking activities and entities. This work aims to structure and organize this proposed regulatory framework and reflects the recommendations regarding the stability of money market funds and their impact on financial stability critically
Institutional determinants of balance of payment dynamics
Get PDFDynamics of Balance of Payment developments are still barely researched. Chapter 1 tries to summarize empirical evidence between institutional determinants and BoP movements and proposes a framework for the role of institutions in a debt cycle. It is found that “good” institutions do help a country to fulfill a positive debt cycle. Chapter two provides empirical evidence for the role of institutions on national savings formation, showing that especially rule of law and low corruption help in increasing national savings. Chapters four and five look at detailed provisions for payment transfer balances in federal monetary unions at the example of the EMU and Fed System. Settlement in the Fed’s ISA system is analyzed and the conditions in the US’ Fed System are compared with the EMU’s framework and possibilities of TARGET2 settlement. Three main preconditions are found which determine the success of a settlement system for payment transfer balances in federal monetary unions
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
