Cover Crops Improve the Vegetative and Reproductive Traits of Peach Trees at the Semiarid Area of El Oasis Sur, Mendoza Province (Argentina)
No full textThe objective of this study was to evaluate the impact of cover crop treatments on vegetative and reproductive traits of peach trees in the semiarid region of El Oasis Sur, Mendoza, Argentina. The treatments comprised mechanical tillage (TC), continuous lucerne cover (TL), and annual common vetch + oats cover (TVO). The current shoot length was observed to have been increased by both the TL (+ 35%) and TVO (+ 29%) treatments. The application of cover crops resulted in an enhancement of fruit diameter by 3–4 mm during the initial year. However, in the subsequent year, the impact was somewhat diminished, with an increase of only 2.4–3.6%. The fruit firmness, as determined one week prior to the harvest, exhibited a notable enhancement from 55.0 to 66.8% under the influence of the cover crops. Furthermore, the TL resulted in a 16.7% augmentation in the number of fruits per tree, which, when coupled with the improvement in fruit size, led to an overall increase in fruit yield of 3–7 kg per tree. The utilisation of cover crops, particularly lucerne, did not result in any adverse effects on the vegetative and reproductive dynamics of peach trees. Conversely, the application of cover crops exerted a beneficial influence on vegetative growth, fruit size, fruit firmness, the number of fruits per tree and overall fruit yield in the peach cv.

Evaluación de materiales de tomate para industria según aptitud varietal en General Alvear (Mza.) : informe preliminar
Full text linkEn general los distintos materiales expresaron un elevado vigor, baja exposición de frutos al sol y un ciclo vegetativo largo con lo cual se recomienda no realizar plantaciones demasiado tardías para lograr buenos resultados productivos..
Los materiales utilizados presentaron condiciones adecuadas para ser utilizados con destino de industria, tanto para entero, cubeteado y pasta sobre todo UG 19406 por presentar mayor consistencia de fruto.
Se destacó la productividad de UG 19406 Y HM 7883 con gran vigor de plantas y elevado número de frutos por planta y peso de los mismos (HM 7883 es el material más utilizado en el país los últimos años).
UG 10109 evidenció una mayor precocidad y uniformidad de frutos siendo estos lo de menor tamaño.
CODE 144, HM 7883 y UG 10109 mostraron mayor presencia de frutos rajados y una menor capacidad de almacenaje a campo (al momento de cosecha mayor presencia de frutos deteriorados).
HM 1892 y SV 2756 si bien mostraron los menores rendimientos también reflejaron los valores más bajos de % de frutos maduros (elevada cantidad de frutos verdes), probablemente debido a un ciclo vegetativo más largo.Fil: Silvestre Levy, Mauro Robert
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
