Analyzing the Determinants of Carbon Emissions from Transportation in European Countries: The Role of Renewable Energy and Urbanization
No full textAmin, Azka/0000-0002-6404-9132; Dogan, Eyup/0000-0003-0476-5177;The continuous growth of transport sector and the increase in carbon emissions from transportation attract the attention of policy makers in sustainable transportation. Therefore, it is of great importance to understand the determinants of pollution from transportation. The aim of this study is to analyze the impacts of economic growth, renewable energy consumption and urbanization on CO2 emissions from transport sector in an Environmental Kuznets Curve (EKC) framework for European countries. To end this, second-generation panel long-run estimates and non-causality test are applied on the dataset from 1980-2014. Empirical pieces of evidence show that increases in renewable energy consumption mitigate carbon emissions from transportation, while urbanization has statistically insignificant positive impact on pollution. An increase in renewable energy consumption reduces CO2 from transportation by about 12 percent. The EKC hypothesis is validated. Moreover, unidirectional causality runs from renewable energy, economic growth and urbanization to emissions in transport sector. The findings of this study suggest strengthening the sustainable transportation system by promoting eco-friendly and energy-efficient modes of transportation and increase the environmental awareness of urban population and their overall concerns related to environmental issues caused by transportation. This study provides concrete evidence to the policy makers of European countries for especially sector-based renewable energy projects, drawing attention to the greenhouse gas impact of European transportation sector.

Driving sustainable development: The impact of energy transition, eco-innovation, mineral resources, and green growth on carbon emissions
No full textAttaining sustainable development depends on closing the disparity between economic development and carbon dioxide emissions. The impact of energy transition, green growth, mineral resource rents, and technological innovation on rebalancing economic and environmental conditions is the subject of significant debate in certain discussion circles. Therefore, the primary objective of this study is to illustrate the efficacy of the indicators above in fostering sustainable development and mitigating carbon emissions in China by employing a wavelet coherence approach covering the period from 1990 to 2018. The outcomes obtained from the wavelet coherence approach demonstrate that non-renewable energy and carbon emissions had strong coherence from 1998 to 2014, with most scale values near 1; however, during 2014–2018, it declined to a moderate level at 16 to 24. Renewable energy indirectly correlates with carbon emissions on a scale of 1–20, suggesting its contribution to improving environmental quality in China. At the same time, green growth demonstrates a positive correlation from 1998 to 2002 and a substantial negative correlation after 2018 on a scale from 1 to 4. During 1998–2014, mineral resource rents and carbon emissions show a significant positive coherence; however, during 2014–2018, the coherence among both indicators is positive but not very high at a period scale of 16–24. The results from spectral causality analysis indicate that non-renewable energy, technological innovation, GDP, and mineral rents are strong predictors of carbon emissions, while green growth and renewable energy show an inverse and weaker relationship with emissions. Concisely, the findings reveal that the consumption of mineral rents, non-renewable energy, technological innovation, economic growth, increase carbon emissions while renewable energy and green growth mitigate carbon emissions in China. The study's findings provide valuable policy implications that are intended to promote the use of renewable energy, foster green growth, technological innovation, and the utilization of mineral resource rents in order to achieve environmental sustainability and emission reduction in China as part of a low-carbon economy. It is further suggested that the successful implementation of these strategies necessitates a sustained commitment and collaborative endeavors
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
