The economic impact of petroleum royalty reform on Turkey's upstream oil and gas industry
No full textAydin, Levent/0000-0001-8179-7418The aim of this paper is to examine the economic impact of the royalty reform. The draft Turkish petroleum Law introduces two important fiscal changes to increase to increase domestic petroleum production, further national petroleum supply, attract investors and harmonize its laws with those of the European Community: (1) progressive sliding royalty relief on oil and gas production leases and (2) 50% of the royalty shall be transferred to province where the production lease exists. Results included in this analysis indicate that there would be 2% increase in oil production thanks to 128 oil fields extending economic life and 0.5% increase in gas production thanks to 63 gas fields due to their profitability in the forecasted period. Half of royalty is transferred to low per capita income provinces and tends to contribute distribution of income. However, half of gas royalty is transferred to high income per capita provinces.

Economic impact of oil price shocks on the Turkish economy in the coming decades: A dynamic CGE analysis
No full textAydin, Levent/0000-0001-8179-7418; Acar, Mustafa/0000-0002-7426-6747As a small open economy, Turkey depends on both imported oil and natural gas, importing almost two-thirds of its primary energy demand. This paper analyzes the economic effects of oil price shocks for Turkey as a small, open oil- and gas-importing country. To analyze the potential long-term effects of oil price shocks on macroeconomic variables of interest, including GDP, consumer price inflation, indirect tax revenues, trade balance, and carbon emissions, we developed TurGEM-D, a dynamic multisectoral general equilibrium model for the Turkish economy. Using TurGEM-D, we analyzed the impact of oil price shocks under three distinct scenarios: reference, high and low oil prices. The simulation results show that these oil prices have very significant effects on macro indicators and carbon emissions in the Turkish economy. (C) 2011 Elsevier Ltd. All rights reserved
Prevalence of anaplasmosis on dairy farms in the european region (thrace) of türkiye: A retrospective study on the effectiveness of two different treatment protocols
No full textThis study was conducted in 2015-2022 to determine the status of anaplasmosis in breeding dairy cattle farms imported from abroad in the Thrace region of T & uuml;rkiye. To investigate the presence of Anaplasma spp. blood samples with EDTA were taken from animals aged two years and older between 05.00 am and 10.00 am. Then a blood smear was prepared with the Diff-Quick staining method and examined under the light microscope at a x 100 magnification with immersion in oil. In addition, 40 randomly selected positive blood samples were analysed by the Nested PCR method. A total of 3,051 blood samples were examined by the Diff-Quick staining method. One hundred eleven of 966 samples (11.49%) in K & imath;rklareli province and 297 of 2,085 (14.24%) samples in Tekirdag province were positive. As a result of nested PCR on 40 randomly selected positive samples from both provinces, the rates of A. marginale, A. centrale, and mixed infection (A. marginale and A. centrale) were determined as 34.5%, 4.0%, and 61.5% respectively. Of the 140 positive cattle, 70 were treated with oxytetracycline (Group 1), and the other 70 ones were treated with oxytetracycline-imidocarb combination (Group 2) twice with two month intervals for comparison. At the third examination, the rate of latent infection in the group treated with oxytetracycline-imidocarb combination was lower than in the group treated with oxytetracycline alone, but the difference was not significant (P > 0.05). As a result, it was revealed that anaplasmosis is a common disease in cattle in the Thrace region, and the combination of oxytetracycline and imidocarb was shown to be more successful than using oxytetracycline alone in reducing latent infected anaplasmosis cases
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
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
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
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
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
