Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Forest reclamation and its economic evaluation in Sokolov region
No full textIn mining and quarrying, carried out surface (whoesale quarry) technologies with large scale devastation of cultural landscape, the equilibrium of the natural ecosystem and also to move and store large amounts of soil material skrývaného. The mining work should be completed by the successful rehabilitation and restoration of land reclaimed their original purpose. The aim is to evaluate the current development of forestry reclamation in the Sokolov coal basin, perform the calculation and assessment of the individual methods of forestry land reclamation, hit siege works. Perform the economic evaluation of the effectiveness of forestry reclamation and evaluated to determine the economic efficiency of forestry reclamation. According to a growing economic results were evaluated forests these species: sessile oak, oak, spruce and larch on dumps William and Big Riesl. By comparing the results obtained using the above procedures was found, when calculating income from timber production unprofitable forestry reclamation projects, but after the inclusion of other functions of forests calculation results were positive in all cases. As the most effective based sessile oak stands, followed by stands of spruce and oak summer
Variations on the Author
Get PDF“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
Analysis of timber prices of the Company Kašperskohorské městské lesy s.r.o for the selected period 2006 - 2015
No full textThis thesis is about an analysis of the change of timber prices of the company Kašperskohorské městské lesy s.r.o. during the years 2006 - 2015. There is an analysis of the development of the market with timber according to the amount and structure of the output. The aim of this thesis is an analysis and evaluation of the selling prices of a chosen company and the assessment of the most important factors which influence the timber price. The conclusion of this thesis is, there are important factors that influence the price but that cannot be influenced by the producer. The analysis includes also factors that can be influenced by the producer and it includes a suggestion of a possible way how to increase the price respectively the income
Use and Economics of fast-growing trees and their impact on the environment
No full textThis Bachelor thesis is focusing on the comparison of different fast growing species of trees (poplar, willow and paulownia). A theoretically calculated yield from one hectare of plantation during its lifecycle has been used for comparison. Lifecycle has been uniformly determined to 18 years. Presumed costs and yields of poplar and willow are very similar. Due to high presumed costs for establishing paulownia plantation, lower presumed profits compared to other fast growing tree species are expected. Economic profitability is mostly dependant on climatic conditions and state support. Under current economic conditions in Czech Republic, a paulownia plantation is less profitable than other compared plantations

It is focused on budgeting, funding sources and asset management of the institution. Management analysis in conditions of the Krkonoše Mountains National Park is also carried out for the last six years
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Marketing study of users satisfaction with wood-buildings in the Regions of Karlovy Vary and of Hradec Králové and their mutual comparison
No full textThis work is focused on ratings user satisfaction wooden buildings in Karlovy Vary and Hradec Kralove region. Information from users was recorded in a pre-prepared questionnaire, which reflects not only their satisfaction with the wooden system, but also their interest in wooden houses, educational attainment and age level users. The results of these inquiries can be used as a basis material for further scientific work in future or for a general improvement in public opinion about wooden system as appropriate building technology for the construction of houses or other buildings.
The first part deals with the physical properties of wood and its history of use for construction purposes. It also contains a variety of mounting options in terms of design and use of diversity in individual regions.
The second part (practical) provides information and evaluation of actual field research in each region processed into graphs, accompanied by commentary for easier understanding of the problem
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
