No full textMarket crashes and value-at-risk models
No full textMany popular techniques for determining a securities firm's value-at-risk are based upon the calculation of the historical volatility of returns to the assets that comprise the portfolio and of the correlations between them. One such approach is the JP Morgan RiskMetrics methodology using Markowitz portfolio theory. An implicit assumption underlying this methodology is that the volatilities and correlations are constant throughout the sample period and, in particular, that they are not systematically related to one another. However, it has been suggested in a number of studies that the correlation between markets increases when the individual volatilities are high. This paper demonstrates that this type of relationship between correlation and volatility can lead to a downward bias in the estimated value-at-risk, and proposes a number of pragmatic approaches that risk managers might adopt for dealing with this issue
International differences in thinking geographically, and why ‘the local’ matters
Full text linkThis chapter explore how geography teachers in four countries understand the discipline of geography and how differences in understanding may affect the representation of the subject in the school curriculum. Drawing upon an international project, using the data collected from teachers in England, this chapter focuses on the implications of these findings, by emphasising how a teacher’s understanding of geography can influence how they view and teach the geography curriculum. This research draws upon Stengel’s (Journal of Curriculum Studies, 29(5), 585–602, (1997) observations that the relationship between academic and school geography has both an epistemological and ethical dimension, and on Bernstein’s (Class, codes and control. Vol. 3. Towards a theory of educational transmissions (2nd ed.). Routledge and Kegan Paul, London, (1977) notion of recontextualisation to understand how the geography curriculum is made and defined locally. The findings reveal the significance of legacy issues within national and local contexts and how these can influence geography teachers, even if they feel a lack of agency as curriculum makers. The implications of this work are significant, as different interpretations of what constitutes geographical knowledge can be seen as barriers to developing internationally agreed understandings. This school-orientated influences can affect how young people are taught to value geography and how they are inducted into thinking geographically
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
