No full textThis dissertation details possible pathways for the European and German energy transition. The open source Global Energy System Model (GENeSYS-MOD) is applied, a multisectoral long-term energy system model, to apply different methodologies accounting for uncertainty in the future energy system. With the goal of outlining challenges and opportunities of the energy system transformation, this dissertation provides common findings and no-regret options found across multiple studies.
Part I of this dissertation focuses on decarbonization pathways and 100% renewable energy systems in Europe. Numerous energy system models are being used, raising the need to adequately assess their results if policy and decision makers should take well-informed decisions. The first chapter draws from previous experience of modeling 100% renewable energy systems and outlines lessons learned from these exercises. Various energy transition pathways are then analyzed and common findings are synthesized which are compared to the efforts of the European Green Deal (EGD). Thereafter, the effects that short sighted decision making could have on the energy system, especially regarding the problem of stranded assets. Key findings of this part highlight the need for open science and clear result communication.
In Part II, challenges and opportunities for the German Energiewende are discussed. It starts by providing a comparison of five different energy system models and analyzes the impact of Germany’s 2030 climate targets on the power system. The following two Chapters explore the effects of key drivers and influential factors on the German energy transition and transportation transition, in particular. Parametric sensitivity analysis is performed, highlighting areas with high impact which policy makers should focus on. It can be shown that demand reductions, next to costs of renewables and carbon prices, have the highest effect on multiple indicators relevant to the success of the energy transition.
Across all chapters of this dissertation, different methodologies to account for various types of uncertainty are applied. The results showcase that, despite uncertain future developments, common findings can be found and no-regret options formulated. In doing so, this dissertation contributes to the ongoing scientific and public debate by showcasing possible pathways, chances, and barriers of the European and German energy transition. In addition, the principles of open science are followed, allowing other researchers or practitioners to validate the findings and use the applied methodologies.In dieser Dissertation werden mögliche Pfadverläufe für die europäische und deutsche Energiewende beschrieben. Das quelloffene Global Energy System Model (GENeSYS-MOD), ein multisektorales Langfrist-Energiesystemmodell, wird eingesetzt, um verschiedene Methoden zur Berücksichtigung von Unsicherheiten im zukünftigen Energiesystem anzuwenden. Mit dem Ziel, die Herausforderungen und Chancen der Energiewende zu skizzieren, leitet diese Dissertation gemeinsame Erkenntnisse aus mehreren Studien ab.
Teil I dieser Dissertation analysiert Dekarbonisierungspfade und 100% erneuerbare Energiesysteme in Europa. Eine steigende Anzahl an Energiesystemmodellen erfordert eine angemessene Bewertung ihrer Ergebnisse, wenn Politiker:innen und Entscheidungsträger:innen gut informierte Entscheidungen treffen sollen. Das erste Kapitel stützt sich auf gesammelte Erfahrungen mit der Modellierung von 100% erneuerbaren Energiesystemen und umreißt die Lehren, die aus diesen Analysen gezogen wurden. Gemeinsame Erkenntnisse aus verschiedene Energiewendepfade werden zusammengefasst, die mit den Bemühungen des European Green Deal (EGD) verglichen werden. Danach werden die Auswirkungen kurzsichtiger Entscheidungsfindung auf das Energiesystem, insbesondere im Hinblick auf das Problem der stranded-assets, dargestellt. Die Ergebnisse dieses Teils unterstreichen die Notwendigkeit klarer Ergebniskommunikation und einer offenen Wissenschaft.
In Teil II werden Herausforderungen und Chancen für die deutsche Energiewende diskutiert. Fünf verschiedenen Energiesystemmodelle werden verglichen und die Auswirkungen der 2030 Klimaziele auf das Stromsystem analysiert. Anschließend werden die Auswirkungen der wichtigsten Treiber und Einflussfaktoren auf die deutsche Energiewende und insbesondere die Verkehrswende untersucht. Es wird eine parametrische Sensitivitätsanalyse durchgeführt, die Bereiche mit hohen Auswirkungen hervorhebt, auf die sich politische Entscheidungsträger: innen konzentrieren sollten. Es zeigt sich, dass Nachfragereduzierungen, neben den Kosten für erneuerbare Energien und den Emissionspreisen, den größten Einfluss auf mehrere für den Erfolg der Energiewende relevante Indikatoren haben.
In allen Kapiteln dieser Dissertation werden unterschiedliche Methoden zur Berücksichtigung verschiedener Arten von Unsicherheit angewandt. Die Ergebnisse zeigen, dass trotz unsicherer zukünftiger Entwicklungen gemeinsame Erkenntnisse gefunden und no-regret Optionen formuliert werden können. Damit leistet diese Dissertation einen Beitrag zur laufenden wissenschaftlichen und öffentlichen Debatte, indem sie mögliche Pfade, Chancen und Barrieren der europäischen und deutschen Energiewende aufzeigt. Darüber hinaus wird den Prinzipien der offenen Wissenschaft gefolgt, die es anderen Forscher:innen ermöglicht, die Ergebnisse zu validieren und die angewandten Methoden zu nutzen.BMBF, 01LN1704A, Nachwuchsgruppe Globaler Wandel: CoalExit - Die Ökonomie des Kohleausstiegs - Identifikation von Bausteinen für Rahmenpläne zukünftiger regionaler StrukturwandelEC/H2020/835896/EU/Open ENergy TRansition ANalyses for a low-carbon Economy/Open ENTRANC
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
