On the centroid of increasing trees
Full text linkCITATION: Durant, K. & Wagner, S. 2019. On the centroid of increasing trees. Discrete Mathematics & Theoretical Computer Science, 21(4). doi:10.23638/DMTCS-21-4-8The original publication is available at https://dmtcs.episciences.org/A centroid node in a tree is a node for which the sum of the distances to all other nodes attains its minimum, or
equivalently a node with the property that none of its branches contains more than half of the other nodes. We
generalise some known results regarding the behaviour of centroid nodes in random recursive trees (due to Moon) to the class of very simple increasing trees, which also includes the families of plane-oriented and d-ary increasing trees. In particular, we derive limits of distributions and moments for the depth and label of the centroid node nearest to the root, as well as for the size of the subtree rooted at this node.National Research Foundation of South Africahttps://arxiv.org/abs/1802.09334v3Publisher’s versio
Der politische Kodex : Die Kodifikationsarbeiten auf dem Gebiet des öffentlichen Rechts in Österreich 1780-1818
No full textParallel zum Allgemeinen Bürgerlichen Gesetzbuch von 1811 sollte in Österreich mit dem so genannten „politischen Kodex“ auch auf dem Gebiet des öffentlichen Rechts eine Kodifikation geschaffen werden. Unter der Federführung Joseph von Sonnenfels’ arbeitete eine Hofkommission seit 1780 an diesem Vorhaben. Mit wechselnden Vorsitzenden und unter verschiedenen Namen dauerten die Bemühungen dieser „Hofkommission in politischen Gesetzsachen“ unter Joseph II., Leopold II. und Franz II. (I.) mit Unterbrechungen bis 1818, ehe die Kommission dann wegen mangelnder Erfolgsaussichten endgültig aufgelöst wurde.
Wie die entsprechenden Pläne aus den Jahren 1791 und 1808 zeigen, orientierte sich der Aufbau des geplanten politischen Kodex maßgeblich an Sonnenfels’ kameralistischem Hauptwerk „Grundsätze der Polizey, Handlung und Finanz“. Darüber hinaus sollte 1808 auch die Staatsverfassung Regelungsgegenstand des politischen Kodex werden. Aus diesem Grund werden auch die staatstheoretischen Positionen in die Untersuchung miteinbezogen, die Sonnenfels bereits 1791/92 im Zuge der von Leopold II. einberufenen Landtage sowie in seinem Gegenentwurf zum „Entwurf eines bürgerlichen Gesetzbuchs von 1794“ vertreten hatte.
Stephan Wagner dokumentiert und analysiert die Geschichte dieses ehrgeizigen und einzigartigen Kodifikationsprojekts vor seinem geistesgeschichtlichen Hintergrund, um schließlich auch der Frage nach den Ursachen für sein Scheitern nachzugehen. Da die entsprechenden archivalischen Quellen durch den Brand des Wiener Justizpalastes im Jahre 1927 stark beschädigt wurden, mussten die Dokumente zunächst in mühevoller Kleinarbeit rekonstruiert werden. Sie werden im Anhang der Arbeit erstmals ediert und der Forschung zur Verfügung gestellt.
Die Arbeit wurde mit dem Kulturpreis Ostbayern der E.ON Bayern AG 2003 ausgezeichnet
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
Il contratto di lavoro tra il progetto italo francese e il corporativismo fascista
No full textIl saggio tematizza il progetto italo-francese delle obbligazioni del 1927 nel contesto della costruzione della concezione corporativa, sotto lo specifico profilo del contratto di lavoro. Il progetto segue di un anno la legge sindacale del 1926 fondata sull'annuncio del corporativismo. Il primo paragrafo delinea vicinanze e distanze tra Italia e Francia nella legislazione lavoristica in tema di contratto di lavoro individuale e collettivo. Nei successivi paragrafi vengono affrontati i nodi concettuali intorno al contratto di lavoro tra locazione e impresa. La concezione comunitaria dell'impresa si collega direttamente al corporativismo nella logica del produttivismo. Nel contesto italiano la dimensione giuslavoristica è sempre più attratta nel corporativismo attraverso il filtro costituito dal concetto di impresa. Emerge dunque un chiaro distacco rispetto all'impianto del progetto del 1927 fondato su una contrattualità introduttiva rispetto alla legislazione sociale
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
