An analysis of the microalgae Technological Innovation System in Germany
No full textMikroalgen werden als vielversprechende Ressource für eine nachhaltige Bioökonomie und Kreislaufwirtschaft betrachtet. Ihre Nutzung spielt dennoch eine untergeordnete Rolle. In der vorliegenden Studie wurde die Relevanz von Mikroalgen als Ressource in Deutschland betrachtet. Die Analyse basiert auf der Betrachtung des technologischen Innovationssystems (TIS), das durch eine Literaturrecherche und Expert*inneninterviews mit Akteur*innen aus der Mikroalgenproduktion, der Wissenschaft, dem Großhandel, dem Anlagenbau und Netzwerken ermittelt wurde. Die Ergebnisse zeigen, dass Mikroalgenanwendungen in einer Vorentwicklungsphase (Bioenergie, Biomaterialien, Ökosystem-dienstleistungen), Entwicklungsphase (hochwertige Moleküle, landwirtschaftliche Produkte) und Wachstumsphase (Nahrungsergänzungsmittel) sind. Die TIS-Funktionen ‚Schaffung von Legitimität‘, ‚unternehmerische Aktivitäten‘ und ‚Marktformierung‘ unterstützen die TIS-Entwicklung. Die Funktionen ‚Wissensverbreitung‘ und ‚Ressourcenmobilisierung‘ limitieren den Fortschritt. ‚Wissensentwicklung‘ und ‚Einfluss auf die Suchrichtung‘ haben einen uneindeutigen Effekt. Basierend darauf wurden drei Blockierungsmechanismen ermittelt. Erstens gibt es keine ausreichende Kooperation zwischen Forschung und Industrie zur Entwicklung von marktfähigen Produkten; zweitens keine ausreichenden Finanzierungsmöglichkeiten für Mikroalgenunternehmen; drittens werden importierte Mikroalgen nicht ausreichend auf Schwermetallbelastungen überprüft. Um diesen Blockierungsmechanismen entgegenzuwirken, wurden drei Politikempfehlungen entwickelt. Erstens die Etablierung von lokalen Innovationsclustern mit gemeinschaftlich genutzten Reallaboren; zweitens die Schaffung eines Finanzierungsprogramms für Mikroalgenunternehmen; drittens die Entwicklung eines Maßnahmenpakets für bessere Importkontrollen und die Unterstützung der lokalen Produktion. Diese Politikempfehlungen haben das Potential zentrale Blockierungsmechanismen im TIS zu vermeiden.Microalgae are considered a promising resource for a sustainable bioeconomy and circular economy that still plays a minor role as a natural resource. This study examined the relevance of microalgae as a resource in Germany. The analysis was conducted through an assessment of the German microalgae Technological Innovation System (TIS), based on a literature review and expert interviews with microalgae producers, researchers, retailers, network actors, and equipment manufacturers. Results show that the food supplement sector is in a take-off phase, while other application areas are still in the pre-development phase (bioenergy, biomaterials, ecosystem services) or development phase (extraction of high-valued molecules, agricultural products). The TIS functions ‘creation of legitimacy’, ‘entrepreneurial activities’, and ‘market formation’ facilitate the TIS development. The system functions ‘knowledge diffusion’ and ‘resource mobilization’ are restricting its progress. ‘Knowledge development’ and ‘guidance of the search’ are characterized by enabling and restrictive impacts. Based on this, three system failures are identified. First, there is a lack of cooperation between research institutions and industry to transfer knowledge into marketable products; second, there is insufficient funding for microalgae companies; and third, there is a lack of control over the import of microalgae with heavy metal contamination. To mitigate these system failures, three policy recommendations were formulated. First, the creation of locally based microalgae innovation clusters in conjunction with a jointly used living lab for sample productions; second, the creation of a separate funding program for microalgae-related companies; and third, the creation of a package of measures with stricter controls at the borders and support of local production. These policy recommendations have the potential to mitigate central system failures in the German microalgae TIS
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.
