Trade, economic growth, and transportation sustainability perspectives of the Gulf-Europe corridor in the GCC countries
Full text linkThe Gulf-Europe transportation project, also known as Iraq’s Development Road Project (DRP), is a transformative supply
chain initiative aimed at constructing a corridor from Al Faw Port in Iraq to Turkey, linking Gulf Cooperation Council (GCC)
countries with Europe. The project’s goal is to establish a robust transport corridor through the extensive construction
of roads and railways, facilitating the fast and seamless movement of goods between the East and the West. By creating
land-based direct transportation routes to complement traditional maritime pathways, the project seeks to reduce transit
times, lower shipping costs, increase trade flows, and improve regional integration. This study qualitatively examines how
the corridor will impact trade, the economy, and transportation sustainability in the Gulf nations. We explore potential
increases in trade volumes, foreign investments, logistics sustainability, and economic diversification within the region.
Additionally, we recommend the adoption of hydrogen fuel cell vehicles (HFCVs) and hydrogen-powered trains in the
corridor to align with the United Nations Sustainable Development Goals (SDGs). Furthermore, we suggest that the
corridor’s development will create opportunities for economic diversification and reduce the GCC countries’ reliance on
oil revenues. Finally, the study provides strategic recommendations for policymakers and stakeholders to maximize the
project’s benefits and address potential challenges, emphasizing its potential to drive long-term economic growth and
strengthen the GCC countries’ global trade positioning
Multimodel Simulations of Hydrogen Refueling Stations: Stock Levels, Infrastructure, and Performance Evaluation Under Stochastic Vehicle Inflows in the Gulf–Europe Corridor
No full textThis study employs multimodel simulations, including road traffic, process, and system dynamics modeling, to analyze hydrogen refueling stations (HRSs) in the Gulf–Europe corridor, also known as the Iraq’s development road project (DRP). It focuses on operational requirements, which consist of stock levels and infrastructure needs, along with refueling performance under stochastic vehicle inflows (SVIs) from the Gulf, European countries, and Iraq’s side roads (SRs). The research aims to identify key operational requirements and evaluate the refueling performance of an HRS for various stochastic vehicle inflow (SVI) scenarios, facilitating the efficient integration of hydrogen fuel cell vehicles (HFCVs) into freight networks. The study introduces novel multimodel simulations developed in the AnyLogic software environment to replicate real-world variability in vehicle inflows. Key findings reveal that SVIs significantly impact hydrogen stock level (HSL), infrastructure requirements (IRs), and refueling performance metrics (RPMs). For example, for a daily transportation demand of 30,000 tons of goods with 10%–20% side road (SR) vehicle entries, an HRS requires an IR-1 of 3, an IR-2 of 2, and an HSL of 44,391.6 kg, with performance reflected in refueling performance metric (RPM)-1 values of 73%, 72%, and 45%, and an RPM-2 range of 1.32–6.12 min. This proves that the HRS requirements and performance vary with SVIs for different transportation demands. Hence, we enhance the theoretical framework of refueling station design by integrating multimodel simulations to address stochastic inflows. It offers actionable insights for policymakers on optimizing HRS operations, improving scalability, and achieving United Nations sustainable development goals (SDGs)
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
