Forest utilisation features in alpine parts of Italy andSlovenia
No full textThe work features concerning the forest utilization performed in North-eastern Italy and Slovenia are analyzed. An overview of the forest environment in both regions is provided and its main characteristics are examined. The peculiarities of the forest enterprises that operate in North-eastern Italy and Slovenia are studied. The study is mainly based on the experiences matured in the sector and it can be supported only in part through data obtained from statistics and surveys. Nevertheless it is possible to consider the state-of-the-art of the forest enterprises and to evaluate the short-medium period perspectives
Different approaches on skidding operation and wood transport investigation:integrate two different approaches in one model
No full textIn order to support an international cooperation in forestry operation, the Forest department of University of Ljubljana and the department of Land, Agriculture and Forestry of University of Padua are validating together a DSS model on forest operation in alpine condition. The project consists on first into verify partial models, independently developed, on valuating skidding operations and transportation of wood,. Models validation consists in exchanging independent approaches and consequently evaluates the results according to individual previous investigations. Once differences have been highlighted, a common DSS model will be developed and consequently apply in a common border productive forest area. The aim of the project is to aid a road map in forest operations in an area where wood raw material is becoming more and more attractive for both wood industry sectors. As a consequent it is becoming fundamental the optimization on wood allocation in terms of wood quality, assortments and supply cost
Evaluating costs on wood supply chain for supporting Slovenian and Italian forest cooperation
No full textThe purpose of the work was to analyse costs of the wood supply chain inside an area lying over borders between Italy and Slovenia. Two SDSS models, developed by University of Padova and by University of Ljubljana, were used to define cutting and skidding systems and their costs. The models consider different list of systems and different algorithms or parameters, but comparing results on the same area (Slovenia) forest utilization costs differ by only 0.8 €. After making cost averages and cumulating allowable cutting wood at road side, transportation costs were evaluated by networking analysis. Two scenarios (with and without boundaries between states) were studied and results show that wood could flow easily from Slovenia to Italy because of lower utilization costs, but also Italian wood could flow to Slovenia if it is far from terminals more than 30 km. Transportation costs are about 30% of total costs, so it would be possible to reduce total costs by introducing new technologies or raising cutting amount in forest compartments with productive function
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
