Robert Heilbrunn and his wife were generous contributors to many organizations. When he was 80, his family established the Robert H. Heilbrunn Chair of Value Investing at Columbia. Other beneficiaries included Mount Sinai Hospital, the American Jewish Committee, the Rockefeller University, the UJA-Federation of New York, and the American Heart Association.https://digitalcommons.rockefeller.edu/group-portraits/1009/thumbnail.jp
Kontextualisierung und Positionierung von Generationenprojekten. Ergebnisse des ersten trinationalen Workshops Generationenprojekte vom 30./31. Mai 2013 in Zürich
Full text linkZahlreiche Forschungsarbeiten im In- und Ausland sowie vielfältige, private, zivilgesellschaftliche und staatliche Initiativen zeigen, dass der Generationenfrage und mit ihr dem Verhältnis zwischen den Generationen gegenwärtig hohe Aufmerksamkeit zuteil wird. Die Gründe für dieses Interesse sind bekannt: Aufgrund des demographischen Wandels wird das Zusammenleben von drei bis vier Generationen zur Regel. In dieser neuen Konstellation werden Risiken und Chancen erkannt: So wird einerseits die Sorge geäussert, dass sich die verschiedenen Generationen wegen des beschleunigten sozialen Wandels auseinanderleben und unterschiedliche Interessenslagen im politischen Bereich in Generationenkonflikte münden könnten. Andererseits wird auf die Chancen und Potenziale hingewiesen, die sich aus dem Zusamenleben mehrerer Generationen ergeben und die sich mittels generationenübergreifender Projekte nutzen liessen.Cite as: Zürcher, Markus & Stoffel, Martine (2014): Kontextualisierung und Positionierung von Generationenprojekten.

Hydrogeomorphic response to extreme rainfall in headwater systems: Flash floods and debris flows
No full textFlash floods and debris flows develop at space and time scales that conventional observation systems for rainfall, streamflow and sediment discharge are not able to monitor. Consequently, the atmospheric, hydrological and geomorphic controls on these hydrogeomorphic processes are poorly understood, leading to highly uncertain warning and risk management. On the other hand, remote sensing of precipitation and numerical weather predictions have become the basis of several flood forecasting systems, enabling increasingly accurate detection of hazardous events. The objective of this paper is to provide a review on current European and international research on early warning systems for flash floods and debris flows. We expand upon these themes by identifying: (a) the state of the art; (b) knowledge gaps; and (c) suggested research directions to advance warning capabilities for extreme hydrogeomorphic processes. We also suggest three areas in which advancements in science will have immediate and important practical consequence, namely development of rainfall estimation and nowcasting schemes suited to the specific space–time scales, consolidating physical, engineering and social datasets of flash floods and debris-flows, integration of methods for multiple hydrogeomorphic hazard warning
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
