Consistent Approach

The purpose of this paper is to define an analytical tool intended to provide a sound, technically justifiable, and consistent approach to analyzing the risk posed by aircraft accidents. The methodology presented in this paper takes into consideration items determined to be important to understanding the risk of aircraft accident and safety appraisal. These items include a number of aircraft operations/flights; crash probabilities; aircraft characteristics; costs, revenues, socio‐economic benefits, value statistical life, etc. The presented case study gives various cost assessments for an A320 crash depending on accident severity and aircraft age. It could be used as a risk assessment tool for implementing safety management system (SMS) process.

To transform the negative impacts of buildings on the environment into a positive footprint, a radical shift from the current, linear ‘make-use-dispose’ practice to a closed-loop ‘make-use-return’ system, associated with a circular economy, is necessary. This research aims to demonstrate the possible shift to a circular construction industry by developing the first practical framework with tangible benchmarks for a ‘Circular University Campus’ based on an exemplary case study project, which is a real project development in India. As a first step, a thorough literature review was undertaken to demonstrate the social, environmental and economic benefits of a circular construction industry. As next step, the guideline for a ‘Circular University Campus’ was developed, and its applicability tested on the case study. As final step, the evolved principles were used to establish ‘Project Specific Circular Building Indicators’ for a student residential block and enhance the proposed design through bioclimatic and regenerative design strategies. The building’s performance was evaluated through computational simulations, whole-life carbon analysis and a circular building assessment tool. The results demonstrated the benefits and feasibility of bioclimatic, regenerative building and neighbourhood design and provided practical prototypical case study and guidelines which can be adapted by architects, planners and governmental institutions to other projects, thereby enabling the shift to a restorative, circular construction industry.

Energy Community

In this paper, we investigate the economic benefits of an energy community investing in small-scale photovoltaics (PVs) when local energy trading is operated amongst the community members. The motivation stems from the open research question on whether a community-operated local energy market can enhance the investment feasibility of behind-the-meter small-scale PVs installed by energy community members. Firstly, a review of the models, mechanisms and concepts required for framing the relevant concepts is conducted, while a clarification of nuances at important terms is attempted. Next, a tool for the investigation of the economic benefits of operating a local energy market in the context of an energy community is developed. We design the local energy market using state-of-the-art formulations, modified according to the requirements of the case study. The model is applied to an energy community that is currently under formation in a Greek municipality. From the various simulations that were conducted, a series of generalizable conclusions are extracted.

The European Union policy strategies on the sustainability of the transport system pursue the goals of maximizing safety and environmental benefits and reducing the severity and frequency of crashes, congestion, and pollutant emission rates. A common issue is the planning of the most effective solution for operational and safety management at intersections. In this study, an egg turbo roundabout is proposed as the alternative solution to a conventional roundabout in Southern Italy which suffers from traffic congestion. A comparative analysis is carried out using microsimulation techniques to investigate the safety effects and operational improvements of converting a traditional priority intersection into standard roundabout or turbo roundabout layout. In particular, the VISSIM software is used to explore the most relevant operational performance measures: queue length, travel times and delays. The lowest values of these measurements are recorded for the simulated turbo roundabout, thus making this scheme more appropriate in terms of operational performances. With regard to safety analysis, the Surrogate Safety Assessment Model (SSAM) is used to collect information on the predicted number of conflicts, the probability, and severity of the potential collisions. The results suggest that, for the specific case study, the safety levels of the standard roundabout and the turbo roundabout are approximately comparable.

So far, China’s particulate pollution control is principally focused on primary particles and sulfur dioxide from coal combustion. The contribution of ammonia emissions to particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 microns (PM2.5) has been increasingly emphasized. As a world-famous agricultural country with 523 million farmers (2017, National Bureau of Statistics of China), approximately 70.0–90.0% of China’s ammonia emissions come from agriculture. With such a huge population, agriculture industrialization (socioeconomic policies and technology upgrades to reduce ammonia emissions from fertilizers and livestock) has a large potential but is more vulnerable to costs compared to other industries. We need a solution involving both economic benefits and environmental protection. For this purpose, we sent out an anonymous questionnaire consisting of 16 questions to 420 farmers and conducted a field visit survey in a rural area of Jiangsu Province. Through statistical analysis, we found that the use of nitrogen fertilizers in agriculture, which are an important source of ammonia through volatilization, is normal (200/420 × 100% = 47.62% of farmers use such fertilizers). Among the 420 farmers surveyed, 90.71% of them have knowledge of air pollution from agricultural activities and 92.15% of them have certain understanding of agricultural industrialization policies, indicating that coordinated control of ammonia emissions can be achieved together with policy propaganda. Through factor analysis and correlation analysis, we find that the early propaganda of policies can help farmers to be more willing to accept the policies. The correlation coefficient between awareness of pollution and policy approval is 0.94, and that between policy publicity and policy approval is 0.95. Generally speaking, the promotion of policies is worth carrying out during the implementation process.

Businesses grounded upon multisided platforms (MSPs) are found in a growing number of industries, thanks to the recent developments in Internet and digital technologies. Digital MSPs enable multiple interactions among users of different sides through information and communication technologies. The understanding of the characteristics and constituents of MSPs is fragmented along different literature streams. Moreover, very few empirical studies have been carried out to date. In order to fill this gap, this paper presents a three-level framework that describes a digital MSP. The proposed framework is based on literature analysis and multiple case study. On the one hand, the framework can be used to describe MSP as it provides an operationalization of the concept through the identification of specific dimensions, variables and items; on the other hand, it can be used as an assessment tool by practitioners, as exemplified by the three empirical applications presented in this paper.
