Early-stage growth performance of apple trees under different biochar application methods in mineral and organic fertilisation regimes
No full textAn one-year field trial was performed in a young apple orchard of the ‘Gala Brookfield Baigent’ cultivar grafted onto dwarfing P 60 rootstock. Three methods of biochar application, i.e. plough incorporation, planting-hole application and surface spreading, each in combination with compost or mineral nitrogen fertilisation, were tested against the fertilisers applied singly and an untreated control. This gave a total of nine treatments, each represented by three replicates arranged in a completely randomised design. A single replicate consisted of four contiguous trees growing in a row.The following basic parameters related to tree growth and fruiting potential were assessed: (i.) trunk circumference; (ii.) total length of current-year shoots; (iii.) number of long shoots; (iv.) number of short shoots; (v.) number of mixed-type buds; (vi.) leaf area, and (vii.) leaf dry matter. The measurements i.–v. were taken during the dormancy period following the first year of tree growth in the orchard. Trunk circumference was measured at a height of 30 cm above the grafting site. Shoots shorter than 20 cm were considered short shoots, while longer ones were considered long shoots. Leaf sampling (measurements vi.–vii.) was carried out during the growing season.The attached data is organised in a long format with column headings explaining their content. Individual parameters are presented in separate files. The file names indicate the names of the particular parameters assessed.</p
Strawberry yield and marketable quality as affected by various inter-cropping practices
No full textA two-year (2022-2024) field experiment evaluated the impact of three inter-crops on the agronomic performance of strawberry (Fragaria × ananassa) cv. ‘Lycia’ in an organic farming system. The inter-croping practices tested were: (i.) flower islands (a mixture of various flowering plants grown as small patches within the strawberry crop); (ii.) flower strip (the same mixture grown on one side along the edge of the crop); and (iii.) living mulch of white clover grown in the strawberry inter-rows. During the experiment, strawberry yields in successive harvest seasons, average fruit weight, hundred fruit weight, the proportion of damaged fruit by cause, as well as fruit colouration and the share of fruit in particular classes of marketable quality were assessed.The attached data are arranged in long format, with column headings explaining their content. Individual parameters are presented in separate files. File titles indicate names of each parameter assessed.</p
Evaluation of sustainable strategies for greenhouse pest control in chrysanthemum and sweet pepper production
No full textThe effectiveness of 16 examples of selected sustainable practices in pest control (i.e. application of plant-derived products, microbial agents or inorganic compounds with expected low environmental impact; simultaneous use of already registered active substances against other harmful organisms, and trap cropping) was tested in the protected cultivation of Chrysanthemum × morifolium cv. ‘Creamist Golden’ and Capiscum annum cv. ‘Ożarowska’ against the two-spotted spider mite (Tetranychus urticae) and thrips (Frankliniella occidentalis, Thrips tabaci).The attached data represent counts of two-spotted spider mite eggs, mobile two-spotted spider mites, and thrips before treatment and on different post-treatment sampling dates. The data are presented in long format, with column headings explaining the content. The file 1_sweet_pepper_trial.xlsx contains the results of the experiment conducted on sweet peppers, whilst the file 2_chrysanthemum_trial.xlsx contains the results of the experiment conducted on chrysanthemums.</p
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
