Chancen der neuen Transpondertechnologie nach ISO 14223 für Tiere
Full text linkElektronische Identifikation von Tieren nimmt in der EU einen immer wichtigeren Stellenwert ein. Im Zentrum dieser Entwicklung stehen die ISO Standards 11784 für die Codestruktur der Transponder und 11785 für die Übertragung der Daten von einem Transponder zu einem Lesegerät. In Zukunft soll ISO 14223 als neuer Standard für Mikrochiptransponder die bereits vorhandenen Standards erweitern und ggf. sogar bei voller Rückwärtskompatibilität ersetzen. Das besondere Merkmal des neuen Standards ist die Möglichkeit, zusätzliche Daten auf den Transpondern zu hinterlegen und somit tierspezifische Daten direkt am Tier verfügbar machen zu können.Ziel dieser Dissertation war es, eine Datenstruktur zu entwerfen, die es zum Einen ermöglicht, eine sehr flexible Datenspeicherung zu gewährleisten, um unterschiedliche Datentypen wie numerische und alphanumerische oder auch Kombinationen zu speichern, und die zum Anderen dennoch in der Lage ist, die Daten so weit zu komprimieren, dass selbst bei sehr geringer Speicherkapazität (derzeitig sind nicht mehr als etwa 4 kbit verfügbar) möglichst viele Daten auf einem Transponder gespeichert werden können. Es war zudem wünschenswert, die Struktur so zu entwickeln, dass eine Integration in bereits bestehende landwirtschaftliche Systeme basierend auf ISO 11787 und ISO 11788 ermöglicht wird.Darüber hinaus werden die Vor- und Nachteile einer solchen Technologie kritisch beleuchtet und Empfehlungen gegeben, wie diese Technologie sinnvoll verwendet werden kann.Electronic identification of animals is a topic which becomes more and more important within the EU. The core pieces of this development are the ISO standards 11784 defining the code structure of the transponders and 11785 which defines the transmission of the data. In future, ISO 14223 shall become the new standard for animal identification. It uses the same techniques as the actual standards, but it allows to store additional data to the transponder. This is not possible with ISO 11784 and 11785. So ISO 14223 covers more functionality in addition to full backward compatibility to the actual standards. This opens the possibility to make animal specific data available right at the animal.It was the task of this thesis to develop a data structure with two major abilities: First, it should allow to store flexible data like numeric or alphanumeric ones or even both in combination. Second, because on an ISO 14223 transponder the memory is actually limited to about 4 kbit, it should be able to reduce the memory needed as much as possible. With these two abilities a flexible storage of data is possible even with very limited memory. Another task was to develop this structure in a way, that it can be included into existing farming systems based upon ISO 11787 and ISO 1178.It will also be discussed, which challenges and benefits are to be expected and the author gives some assessments on how this technology can be used in reasonable way
Development of a database for the new ISO 14223 animal transponder generation

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
