Practices for the Adjustments of Changes in Cost for Construction Projects due to the Inflation of Material Prices in our Region
No full textConstruction projects take time to be completed, and during this period sometimes the changes of prices in construction field have considerable influence in the overall budget for that project. In the good practice regarding this issue, in the offered documentation is presented how this will be taken into account if the prices are changed over a certain limit. If not, then the contracting authority and the contractor have to find an accepted method approach, how these changes will be applied in the overall cost. Here in the paper will be presented some of the practices for the adjustments of changes in the cost that can be applied as a method in order to take into consideration the changes of prices during the implementation period for the contracts in our region
Correlation between Density in situ and Deformation Modulus
No full textDensity in situ and deformation modulus are two of the most common tests applied to control parameters of soil and layers during the construction of transportation lines. Given that the deformation modulus test is performed for a relatively short time then it is very important to find the correlation between these two tests for each type of soil or layer in order to know the approximate value of density in situ immediately. In this paper we have presented statistical data from field tests and comparative values that have been obtained
Applicable Method for Revision of Unit Prices for Long-term Construction Contracts
No full textDepending from the scope of work, some construction projects take time to be completed, and during this period changes in aspect of cost have considerable impact in the overall initial budget. Usually, in the bidding documentation is presented how this will be taken into account if the prices are changed over a certain limit. If not, then the contracting authority and the contractor have to find an accepted method approach, how these changes will be applied in the overall cost. Here in the paper will be presented a way which is practicable and it is presented in well-known form of contracts for the revision of the construction cost that can be applied as a method in order to take into consideration the changes of prices during the implementation period for the long-term contracts
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
The Impact of Coal Quality on Reduction of Environmental Pollution Researched Through Statistical Analysis
Full text linkToday, the region in general but also Kosovo faces a lack of electricity on the one hand and environmental pollution on the other hand from existing power plants where electricity is produced for the community in general in thermo-plants Kosovo A and Kosovo B. The purpose and importance of this paper is that for the samples taken through the layers (floors) of coal by drilling to extract the calorific values of coal (ETU) and the percentage of ash, whose parameters were analysed in the laboratory of geo-mechanics according to the standards (ISO 9001) in order to eliminate the weak part of coal that would have a positive impact on increasing electricity production but also on reducing environmental pollution within the allowed values according to European Union standards. To carry out this work, a large number of drillings were performed from which 91 samples were taken at different depths, these samples were analysed and, at the same time, statistical processing was done in order to find the average caloric value of (ETU) and the content of ash with the lowest value, these parameters will help us to determine the method to be applied during the exploitation in order to create better conditions for the transport process to the power plants by means of conveyor belts and, at the same time raising the quantity of energy production and reduction of carbon dioxide (CO2).

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
