Drought responses at leaf, stem and fine root levels of competitive Fagus sylvatica L. and Quercus petraea (Matt.) Liebl. trees in dry and wet years
No full textThe inter-annual variability of four growth-related parameters (light-saturated photosynthesis A,,, leaf area index L, annual stem diameter growth S, and fine root production P) was investigated together with various leaf water status parameters in adult Fagus sylvatica and Quercus petraea trees during five summers with weak, moderate or severe soil water deficit. Study aims were (i) to identify differences in drought sensitivity among the tree organs (leaf, stem or root) and between the tree species, and (ii) to test the hypothesis that differences in whole-tree drought response are relevant for competition between Fagus and Quercus in Central European mixed stands. Drought had only weak or no influence on A,, and L of the two species during the 5 years; the only exception being a severe drought in 1990 with an A,,, reduction of Fagus by 30%. Stem diameter growth of Fagus was significantly smaller in dry than in wet summers; in contrast, no clear stem growth/moisture relationship was detected for Quercus during the study period. Soil water deficits apparently stimulated fine-root,growth of Fagus during the dry mid-summer 1995, thus compensating for root biomass losses due to high root mortalities in this period. Quercus fine-root biomass and productivity were not significantly influenced by this drought. A higher drought sensitivity of stem diameter growth, fine-root production and photosynthesis in Fagus corresponded to a larger inter-annual variability of the predawn leaf water potential between wet and dry summers and generally smaller leaf conductances of this species compared to Quercus. Quercus was less sensitive to drought in its growth processes, but showed larger inter-annual variabilities of the osmotic potentials of the leaf symplasm and of the seasonal minima of bulk leaf turgor compared to Fagus. Thus, Fagus is competitively superior in mixture with Quercus despite its higher sensitivity to soil water deficits. It is concluded that a whole-plant perspective rather than a leaf-centred view of drought response is needed to predict the consequences of water shortage for ecosystem-level processes, such as tree competition and succession driven by climate change.

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
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

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

La propuesta que se presentará a continuación construye, en parte, sobre los conceptos vigentes, como las redes sociales, la teoría de la acomodación (Giles, Coupland y Coupland, 1991) o el desplazamiento de una lengua (language shift) aunque esto no esté explícito en el texto
