The bad old days are back? A structural and neoclassical realist assessment of Russian foreign policy
No full textModern realists are keen on using Russia’s increasingly assertive foreign policy posture to argue for the realist nature of international politics. In an attempt to gauge the cogency of such claims, this research applies two contemporary realist theories, structural realism and neoclassical realism, to Russia’s foreign policy from 1992 to 2014. I find that the explanatory power of structural realism remains limited as it would expect Russia to increase military spending and display balancing behavior towards its biggest objective rival: China. Instead, while mostly decreasing military spending, the vast majority of its external balancing behavior is directed towards the US. Neoclassical realism, with a focus on the filtering effect of worldviews of the country’s foreign policy executive, and applied to the founding of the SCO, seems much more apt to account for such deviant behavior as it explicates how Putin’s worldviews logically turned the US into Russia’s antipode and thus its most objective rival
River flood reconstruction in the Lower Rhine valley and delta : Water levels and discharges in past landscape contexts
No full textThis thesis examines the largest floods of the Lower Rhine river over the past centuries to millennia (Late Holocene to historic time frame). Its central objective is to quantify these events. First, the thesis determines maximum water levels in the past based on sedimentological interpretation of archaeological stratigraphy and geographical survey of epigraphic marks. Next, it provides detailed reconstructions of the alluvial terrain of the Lower Rhine valley and delta, covering the early modern channel bathymetry restored from historic maps and the medieval floodplain topography restored from geomorphological analysis and interpolation. The past landscape context then serves to set up a palaeoflood hydraulic model that resolves the discharges of the largest floods by linking the simulation results to reconstructed water levels. The insights gained in this thesis may ultimately contribute to the design of future flood protection measures.
The overarching findings demonstrate that reliable quantification of past floods in lowland river settings necessitates a two-dimensional approach, when it comes to the required flood level and landscape reconstructions and the discharge calculations. Furthermore, the findings show that palaeoflood research benefits from a multidisciplinary approach, with the primary methodological focus depending on the selected casus and targeted time period. The results include successfully reconstructed pre-instrumental flood levels across the Lower Rhine valley and delta by integrating archaeological, geological, and historical sources (Chapters 2, 3, and 6). Additionally, the results encompass successful reconstructions of the landscape for two key periods: before the onset of river normalisation in the mid-nineteenth century and before the onset of embankment in medieval times (Chapters 4 and 5). Finally, the thesis provides an estimate for the ‘millennial’ discharge in the Late Holocene by numerical flood simulations in the pre-embanked landscape context, resulting in a value of 14,000 m3/s (Chapter 6). Further output of the Floods of the Past, Design for the Future project shows that the landscape context prior to normalisation is crucial to constraining discharge magnitudes of individual historic flood events
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
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
