Data Structures and Advanced Models of Computation on Big Data (Dagstuhl Seminar 14091)
No full textThis report documents the program and the outcomes of Dagstuhl Seminar 14091 "Data Structures and Advanced Models of Computation on Big Data". In today's computing environment vast amounts of data are processed, exchanged and analyzed. The manner in which information is stored profoundly influences the efficiency of these operations over the data. In spite of the maturity of the field many data structuring problems are still open, while new ones arise due to technological advances.
The seminar covered both recent advances in the "classical" data structuring topics as well as new models of computation adapted to modern architectures, scientific studies that reveal the need for such models, applications where large data sets play a central role, modern computing platforms for very large data, and new data structures for large data in modern architectures.
The extended abstracts included in this report contain both recent state of the art advances and lay the foundation for new directions within data structures research
Exploring Climate Change-Induced Physical Risks in the Electronic Equipment Manufacturing Supply Chain Using ISO 14091:2021
No full textKlimatförändringar påverkar i allt högre grad globala leveranskedjor, särskilt genom fysiska risker såsom översvämningar och extremväder. Denna avhandling undersöker hur ISO 14091:2021 – en relativt ny och fortfarande underutnyttjad standard – kan stödja bedömningen av klimatrelaterade fysiska risker inom elektronikindustrins leveranskedjor. Genom en kvalitativ fallstudie vid en europeisk anläggning tillämpas de inledande stegen i ISO 14091:2021 ramverket för att identifiera och prioritera relevanta klimatrelaterade fysiska risker samt för att fastställa vilken information som krävs för att bedöma exponering, känslighet och anpassningsförmåga. Kraftig nederbörd och pluviala översvämningar identifierades som de mest relevanta riskerna för det aktuella fallet, med hänsyn till potentiella effekter på infrastruktur, känsliga lager och leveranssäkerhet. Avhandlingen redogör även för centrala informationsbehov kopplade till dessa bedömningar. Även om en fullständig tillämpning av ISO 14091:2021 låg utanför avhandlingens omfattning, visar resultaten att det strukturerade angreppssättet användes för att identifiera prioriterade risker och informationsbehov, vilket bildar en praktisk grund för att påbörja systematiska klimatrelaterade riskbedömningar och anpassningsplanering inom elektronikindustrins leveranskedjor.Climate change increasingly affects global supply chains, particularly through climate change-induced physical risk such as floods and extreme weather. This thesis explores how ISO 14091:2021, a relatively recent and still underapplied standard which can support the assessment of climate change-induced physical risks in the context of electronic equipment manufacturing. Using a qualitative case study at a European facility, the study applies the early steps of the ISO 14091:2021 standard, including system scoping, risk screening, and identification of information needs. Heavy precipitation and pluvial flooding were identified as the most relevant risks for the case, based on potential impacts on infrastructure, sensitive inventory, and supply continuity. The thesis also outlines key information requirements related to exposure, sensitivity, and adaptive capacity. While the full implementation of ISO 14091:2021 was beyond the scope of this thesis, the findings suggest that its structured approach was applied to identify priority risks and assess key information requirements, forming a practical basis for initiating systematic climate risk assessment and adaptation planning in the context of electronic equipment manufacturing supply chains
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
