Blockchain Technologies in Logistics and Supply Chain Management: A Bibliometric Review

Horst Treiblmaier Abderahman Rejeb Karim Rejeb Steve Simske

Publication Name: Logistics

Publication Date: 2021-12-01

Volume: 5

Issue: 4

Page Range: Unknown

Description:

The emergence of blockchain technology has sparked significant attention from the supply chain management (SCM) and logistics communities. In this paper, we present the results from a thorough bibliometric review that analytically and objectively identifies the intellectual structure of this field, the seminal papers, and the most influential scholars. We employ a knowledge domain visualization technique to generate insights that go beyond other review studies on blockchain research within logistics and SCM. The analysis starts with selecting a total of 628 papers from Scopus and the Web of Science that were published during 2016–2020. The bibliometric analysis output demonstrates that the number of blockchain papers has rapidly increased since 2017. The most productive researchers are from the USA, China, and India. The top academic institutions contributing to the literature are also identified. Based on network analyses, we found that the literature concentrates mainly on the conceptualization of blockchain; its potentials for supply chain sustainability; its adoption triggers and barriers; and its role in supporting supply chain agility, trust, protection of intellectual property, and food/perishable supply chains. Besides systematically mapping the literature, we identify several research gaps and propose numerous actionable research directions for the future. This study enriches the extant blockchain literature, provides a timely snapshot of the current state of research, and examines the knowledge structure of blockchain research in logistics and SCM with the help of evidence-based scientometric methods.

Does urban shrinkage impact energy efficiency?: Evidence from Chinese counties

Hyoungsuk Lee Xin Zhao Yang Yang Peijun Xie Hui Li Wenxing Jia

Publication Name: Renewable Energy

Publication Date: 2025-01-01

Volume: 238

Issue: Unknown

Page Range: Unknown

Description:

Some cities in China are facing challenges due to population loss while also attempting to address energy conservation and emissions reduction. Although urban shrinkage can relieve pressure from energy consumption demands, such as water, electricity and gas, does it improve urban energy efficiency? This study attempts to answer this question. Based on Point of Interest (POI) big data and Global Human Settlement Layer (GHSL) raster data, this study identifies urban shrinkage from the coupling perspective of administrative and economic boundaries. It also examines the impact of urban shrinkage on energy efficiency. The results suggest that Chinese counties’ overall energy efficiency is experiencing a four-stage “decline-rise-decline-rise” trend, and the urban shrinkage of Chinese counties exists in three major areas: the Northeast, the Southwest, and the Centre. Compared to non-shrinking cities, urban shrinkage has a significant negative impact on improving energy efficiency. This impact exhibits significant heterogeneity. Specifically, compared with mature resource cities and cities in Western China, regenerative cities, non-resource cities and cities in Central China have less impact on energy efficiency. In addition, urban shrinkage may impede energy efficiency improvement by hindering industrial structure transformation and upgrading, energy-saving technology innovation, and financial development. Clarifying the relationship between urban shrinkage and energy efficiency is helpful for shrinking cities to change their development strategies, which is critical for sustainable development.

A Canonical Set of Operations for Editing Dashboard Layouts in Virtual Reality

None Csapó Tarek Setti

Publication Name: Frontiers in Computer Science

Publication Date: 2021-07-12

Volume: 3

Issue: Unknown

Page Range: Unknown

Description:

Virtual reality (VR) is a powerful technological framework that can be considered as comprising any kind of device that allows for 3D environments to be simulated and interacted with via a digital interface. Depending on the specific technologies used, VR can allow users to experience a virtual world through their different senses, i.e., most often sight, but also through touch, hearing, and smell. In this paper, it is argued that a key impediment to the widespread adoption of VR technology today is the lack of interoperability between users’’ existing digital life (including 2D documents, videos, the Web, and even mobile applications) and the 3D spaces. Without such interoperability, 3D spaces offered by current VR platforms seem empty and lacking in functionality. In order to improve this situation, it is suggested that users could benefit from being able to create dashboard layouts (comprising 2D displays) for themselves in the 3D spaces, allowing them to arrange, view and interact with their existing 2D content alongside the 3D objects. Therefore, the objective of this research is to help users organize and arrange 2D content in 3D spaces depending on their needs. To this end, following a discussion on why this is a challenging problem—both from a scientific and from a practical perspective—a set of operations are proposed that are meant to be minimal and canonical and enable the creation of dashboard layouts in 3D. Based on a reference implementation on the MaxWhere VR platform, a set of experiments were carried out to measure how much time users needed to recreate existing layouts inside an empty version of the corresponding 3D spaces, and the precision with which they could do so. Results showed that users were able to carry out this task, on average, at a rate of less than 45 s per 2D display at an acceptably high precision.

Proposal of an Autonomous Vehicle Control Architecture

Claudiu Pozna Csaba Antonya

Publication Name: Ines 2021 IEEE 25th International Conference on Intelligent Engineering Systems Proceedings

Publication Date: 2021-07-07

Volume: Unknown

Issue: Unknown

Page Range: 37-42

Description:

In this paper, a control program architecture is proposed for autonomous vehicles. This set of programs is structured in a hierarchy and it is inspired by the human driver behavior. It contains three levels connected by specific links: the strategic, the tactical, and the operational level. Autonomous vehicles and human-driven vehicles will share the roads in future transportation systems. The human-like driving behavior will allow other participants to predict the autonomous vehicle's behavior.

Page Range: 18-23

Description:

EDP PROTUGAL OFFICE BUILDING, LISBON, PORTUGAL ARCHITECT: ALEJANDRO ARAVENA Located on the heterogeneous, redeveloping Tagus riverfront in Lisbon, the second phase of the EDP headquarters by Alejandro Aravena's firm, ELEMENTAL, presents a powerful exercise in civic and environmental responsibility. Standing in dialogue with the project's first phase by Aires Mateus, this new office building adopts the established perpendicular-to-the-river site plan but reinterprets it with a profound focus on the public realm. Manifesting a dual-character structure: a transparent, glazed facade houses the workspaces, while a heavy, monolithic concrete mass confronts the city, sculpted to function as a piece of urban topography. This robust, rock-like form, conceived as infrastructure akin to ancient city walls, defines a new sloping public space that invites the city's lively circulation inward and culminates in a cantilevered viewpoint over the river. The building’s massive concrete structure acts as a thermal mass for passive cooling, while the interiors contrast the stark exterior with warm use of wood. The project is thus a complex architectural statement that is both a sculptural object and an integrated piece of the urban fabric, designed to prioritize public life and social interaction.

A New Strategic Marketing Management Model for the Specificities of E-Commerce in the Supply Chain

Laszlo Vasa Yuriy Bilan Balázs Gyenge Imre Vida Zoltán Máté

Publication Name: Journal of Theoretical and Applied Electronic Commerce Research

Publication Date: 2021-07-01

Volume: 16

Issue: 4

Page Range: 1136-1149

Description:

The study seeks to answer the question of what strategic directions and opportunities we have for business in the midst of the info-communication changes of our time. In this research, we compare the results of non-representative primary research (cluster analysis and discriminant analysis) with the factors and latest methods of e-commerce or even mobile commerce and traditional commerce and their main differences. Based on the four clusters examined, we develop a new strategic model for practice with suggestions which can be used by small and medium-sized enterprises (SMEs) and which they can incorporate directly into their business models. Starting point of our hypothesis was that in order to develop an effective and delivered communication, a market needs to be targeted and at least four different clusters should be formulated.

FORTRESS, WITH OPEN POSSIBILITIES: ELEMENTARY SCHOOL, ÉRD, HUNGARY

Krisztina Somogyi

Publication Name: Metszet

Publication Date: 2025-01-01

Volume: 16

Issue: 4

Page Range: 36-43

Description:

In an uncertain physical and intellectual environment, a presentation that suggests safety and a well-structured order is likely the best architectural strategy when designing a school. The idea of Érd Fenyves Parkváros Public Education Center started in 2016 with poorly articulated intentions, thus without a significant professional program or partners. Observing the functioning of the school that was handed over a couple of years ago and has been inhabited for a year and a half, the building has many spatial qualities that are still untapped. Led by Tamás Karácsony, György Major, and Péter Klobusovszki, the 24-classroom primary school created in the 'Vertical Workshop' of the Department of Public Building Design at BME may seem like a traditional fortress, but it could also serve as a pedagogy center that opens up to communities and offers alternatives.
