Description: An electric road system (ERS) is a transportation solution that provides electricity for fully electric vehicles while in motion. This solution might contribute to sustainable transportation by overcoming range anxiety problems that fully electric vehicles, especially heavy vehicles, have encountered due to battery technology limitations. However, large-scale ERS implementations are challenging, both technically and socially. An ERS is not only an engineering project, but also a complex technology innovation system composed of multiple subsystems and stakeholders, which requires an interdisciplinary means of aligning relations, problems, and solutions. In the policy analysis domain, researchers have developed actor analysis methods to support policy making processes. Actor analysis methods can provide an analytical reflection in solving complex multi-actor policy making challenges that ERSs are also facing. To uncover the complexity of multiple subsystems and stakeholders involved in an ERS, this paper applied a method to align system characteristics with the stakeholders’ perceptions to understand multi-stakeholder contexts in complex technology innovation projects. Desk research was first conducted to summarise ERS characteristics. Then, the dynamic actor network analysis method framework was adopted to establish an action, factor, goal (AFG) list, which was revised by independent researchers. Next, the AFG list was used to collect the perceptions of the ERS stakeholders, expressed as AFG selections and causal links through stakeholder interviews. The resulting AFG list was iterated through two rounds of interviews and then validated in a Swedish ERS case workshop. The results from this methodology showed that the actor analysis method can not only be applied to policy analysis domains, but can also be applied to technology innovation complex systems, using the electric road system as a case study, to help uncover the ERS complexity from the concerns of stakeholders and to secure a pathway towards sustainable technology implementation.

Description: This paper proposes a simulation-based framework for assessing airborne self-separation procedures in flow corridors with consideration of different performance metrics, including air traffic operations, corridor capacity, safety, and environmental impacts. Firstly, the airborne self-separation concept in flow corridors is introduced, followed by an agent-based flow corridor simulation model. Then, data were collected to initialize a parallel-lane flow corridor model connecting A461 upper air route from Beijing to Guangzhou in China which can also simulate aircraft self-separating in the flow corridor. The total control delay, flow corridor throughput, breakout rate, and the CO2 emissions of traffic flow were considered as the impact measurements, and the TOPSIS and entropy method was used to rank the performances of different self-separation procedures. We found that combining multiple objectives into one, the optimum scheme can be obtained to guide the design of self-separation procedures for flow corridors. The research results can be used by airspace managers to dynamically develop appropriate operational procedures and rules for flow corridors given different operational conditions and constraints. Also, the framework proposed in the research may be used to evaluate the design of airspace structure with consideration of multiple objectives.

Description: Most soybean oil consumed in China is made from imported genetically modified (GM) soybeans, while livestock are fed imported GM soy meal and GM corn. However, no GM food crops are allowed to be planted in China at present. That puts China in a confusing situation where GM foods can be eaten but cannot be grown. Many studies suggest that it is partially due to Chinese consumers’ and government officials’ opposition to GM technology. This is the first study that examines different stakeholders’ and journalists’ attitudes toward the commercialization of GM non-food crops and GM food crops and investigates the attitude gaps with respect to these crops. From 2015 to 2016, surveys were conducted face-to-face and by email with 1730 respondents, including 1460 consumers, 54 farmers, 70 journalists, and 146 agricultural officials. We find that nearly 60% of respondents are supportive of the commercialization of GM non-food crops, but less than 30% of respondents support the commercialization of GM food crops. Around 50% of respondents have no confidence in the government’s management of biotechnology, while only 17% have confidence in the government’s management. Those with lack of confidence in the government’s management are less likely to support the commercialization of GM crops.

Description: This article presents assessment results for the priorities of different urban logistics stakeholders in order to launch crowd logistics (CL) solutions within a city area. Additionally, this analysis was conducted by using various dimensions of sustainable city development. The unique character of this study lies in presenting the priorities of the interviewed stakeholders. Therefore, the purpose of this publication is to analyze the priorities of various stakeholders in relation to the introduction of CL solutions within a city area. The reason for such analysis is the rapid development of a large number of sharing-economy initiatives, including services. For this study, a few methods were used to achieve the research goal. Firstly, text mining and text analysis methods were implemented to analyze the opinions of the interviewees. Then, two chi-square tests allowed us to determine whether the groups of stakeholders are statistically different or not. Finally, the AHP (analytic hierarchy process) and DEMATEL (decision making trial and evaluation laboratory) methods were applied in order to define the priorities of the stakeholders. The needs of particular groups of respondents were derived from the interview based on the questionnaire. The results of the analysis allow for defining the demand characteristics for CL solutions by presenting the areas that are crucial for particular groups of stakeholders.

Description: There is a very clear link between tourism and sustainability due to the importance and consequences of the tourism sector in the world economy. Behavioural studies are among the major topics of sustainable tourism research. There are several factors that influence our sustainable behaviour at home and in vacation settings. In general, the main objective of this paper is to examine the personal factors in pro-environmental tourist behaviour from a gender perspective. This study is based on a sample of 347 golf tourists from 16 European countries. The results corroborated the relationships between ecological habits, personal capabilities and environmental attitudes. However, interactions between personal factors were more limited. It was shown that only the interaction between personal capabilities and externally-oriented habits have an influence on environmental attitudes. Also, some gender differences were found.

Description: The dynamic structure-soil-structure interaction (SSSI) involving three adjacent structures with pile-raft foundations arranged along the east-west direction in a viscoelastic half-space is numerically studied under earthquake excitation. The direction of earthquake excitation is perpendicular to the direction of the structural arrangement. In the simulation, the Davidenkov model of the soil skeleton curve is assumed for soil behavior, and the viscous-spring artificial boundary is adopted. In order to investigate the effects of SSSI, the clear distance between structures, structure types, structure heights, and the first natural periods of structures are considered, and a series of numerical simulations are conducted. The peak floor displacement and the peak inter-story shear force of structures are examined to determine the SSSI effects. Results show that SSSI effects change significantly with these factors. Furthermore, the structural seismic response could be increased or reduced as a result of SSSI, depending mainly on the structural characteristics, rather than the location of the structures. These results are significant for studying the effects of SSSI and the sustainable development of cities, especially for the seismic design of dense urban buildings.

Description: In this period of increasing urbanization, cultural heritage can play a key role to achieve sustainable development, as widely recognized by international institutions (i.e., United Nations (UN), UN Educational, Scientific and Cultural Organization (UNESCO), International Council on Monuments and Sites (ICOMOS)). In this perspective, it is necessary to operationalize the principles stated at international level and thus new approaches and tools are required. The paper aims to understand the relationships between the implementation of adaptive reuse projects and their success (or not) in terms of impacts on the buildings themselves and on the urban context. The assessment framework for evaluating the impacts of heritage conservation and rehabilitation projects is described through the analysis and comparison of two Italian case studies: the Ancient Market and the Basilica of St. Peter the Apostle, in Siracusa (Italy). Although realized both in the same place (Ortigia, the historic centre of Siracusa), during the same period and by the same architect, these two interventions have produced different results in terms of urban development. A set of indicators, deduced from recent scientific studies, has been used to analyse the different impacts on physical, cultural, social, environmental and economic systems. To understand in depth the causes of these two different results, a survey has been carried out involving experts. The proposed indicators used for the ex-post evaluation can be also adopted in other contexts and for ex ante evaluation, in order to orient the strategic design choices in cultural heritage adaptive reuse projects.

Description: In light of the increased demand for greater accountability and legitimacy, new disclosure mechanisms based on non-financial transparency have emerged. Universities cannot be left behind with respect to these social demands. In addition, continuous competition in excellence is driving higher education organizations to exhibit a greater visibility of their results, necessarily incorporating more non-financial aspects to boost stakeholder engagement. The novelty of this work lies in the analysis of the real state of non-financial vs. financial information in both public and private universities and in the exploration of their influence on stakeholder online engagement. To this end, a content analysis of the universities’ web pages and Facebook profiles was conducted, and a multivariable linear regression analysis was performed. The main results show that private and larger universities that lead Webometrics for Google Scholar Citations, and those that have gradually been adopting financial reporting, are the most interested in implementing Facebook as a two-way communication strategy. It seems that stakeholders react more to financial transparency and, therefore, universities still prefer financial disclosure to improve accountability.

Description: Soil moisture sensors can be effective and promising decision-making tools for diverse applications and audiences, including agricultural managers, irrigation practitioners, and researchers. Nevertheless, there exists immense adoption potential in the United States, with only 1.2 in 10 farms nationally using soil moisture sensors to decide when to irrigate. This number is much lower in the global scale. Increased adoption is likely hindered by lack of scientific support in need assessment, selection, suitability and use of these sensors. Here, through extensive field research, we address the operational feasibility of soil moisture sensors, an aspect which has been overlooked in the past, and integrate it with their performance accuracy, in order to develop a quantitative framework to guide users in the selection of best-suited sensors for varying applications. These evaluations were conducted for nine commercially available sensors under silt loam and loamy sand soils in irrigated cropland and rainfed grassland for two different installation orientations [sensing component parallel (horizontal) and perpendicular (vertical) to the ground surface] typically used. All the sensors were assessed for their aptness in terms of cost, ease of operation, convenience of telemetry, and performance accuracy. Best sensors under each soil condition, sensor orientation, and user applications (research versus agricultural production) were identified. The step-by-step guide presented here will serve as an unprecedented and holistic adoption-assisting resource and can be extended to other sensors as well.

Description: Farmland exhibits multifunctionality by preventing flooding and soil erosion and providing social and cultural community comfort. All these functions are essential for sustainable rural development. However, the multifunctionality of farmland is decreasing worldwide because of an aging society, depopulation and income disparity between flat lands and hilly mountainous lands. Regarding the consequences of abandonment, abandonment is intimately linked with the wider issue of the stagnation of the rural economy. The direct payment policy for hilly mountainous land is aimed at restraining farmland abandonment through community-based activities. The panel data difference in differences (DID) estimator was employed to observe the effect of direct payments on the rate of restraining farmland abandonment at the municipality level of the Hokkaido prefecture in Japan for the period of 2005–2015. We estimated that the direct payment implementation provided a 2% effectiveness for restraining the increase in the rate of abandonment as the result of DID estimation. On the other hand, the age group of 65 years or older was negatively correlated with farmland abandonment, which contradicts the general understanding. Older farmers have relatively more interest in contributing to and preserving their community. Therefore, the direct payment can encourage them to participate more in their community preservation. From these results, we concluded that it is necessary to promote farmland consolidation to compensate for the lack of inheritors. In addition, providing direct payment for a well-organized community or active stakeholders can be an effective way of utilizing governmental budgets and sustaining rural development.
