Abstract

Purpose

The aim of this paper is to clarify the spatial multi‐criteria workflow for stakeholders and decision makers, for which feedback rankings are vital to the success of the transportation planning.

Design/methodology/approach

The experimental approach was designed to integrate in a novel fashion both analytical hierarchy process (AHP) and multi‐criteria decision making (MCDM) within a geospatial information system (GIS) framework to deliver visual and objective tabular results useful to estimate environmental costs of the alignments generated. The method enables ranking, prioritization, selection, and refinement of preferred alternatives. The Interstate‐269, the newly planned bypass of Memphis‐TN, for which a recent environmental impact study (EIS) was completed, was selected as the experiment test‐bed.

Findings

The results indicate that the approach can automate the delivery of feasible alignments that closely approximate those generated by traditional approaches. Furthermore, via integration of local planning and ancillary spatial data, the method provided alignment results that avoided areas where local opposition was noted in the EIS. This enhanced method based on remote sensing and spatial information technologies delivers low or high‐predicted environmental costs per feature criteria and cumulative predicted costs while preserving local values and plans.

Practical implications

The method is highly transferable and limited solely by the availability of sources of geospatial data and coordination with stakeholders. The approach was implemented to derive results similar to traditional approaches with benefits in time, costs, and quality of solutions.

Originality/value

A novel adaptation of MCDM and AHD within a spatial decision‐making framework is presented. The paper suggests a clarification of multi‐criteria workflow to design and select least‐environmental‐cost corridors. The case study application provides a starting point to develop practical tools that delivers environmental benefits through a collaborative process capturing stakeholder values and decision maker opinions.

Abstract

Purpose

The global pandemic has had a considerable effect on organisations’ performance and development and on the daily lives of the general population. This study aims to analyse the recent literature on the topics of Covid-19 and sustainability and proposes to rethink and redefine sustainability with the intersection of human health as a fourth sustainable pillar.

Design/methodology/approach

Using the Scopus and ISI Web of Science databases, 119 articles were analysed in detail and classified according to concepts and principles for achieving sustainable development, based on the Brundtland Report, 1987.

Findings

The results indicate a high number of publications in the social dimension, with a relevant proportion of studies in the health sector. This study allows us to conclude that all sectors of society are being affected by the pandemic. However, the enormous tension and the immediate impact felt by the health sector during the pandemic reflect directly on the population, and there are clear signs that in the medium and long term, instability and uncertainty in the environmental, economic and social dimensions will remain. In national health systems, monitoring, innovating in human resource management and investing in information technology can ensure organizations’ reliability and sustainability. The conclusion involves the suggestion of introducing health as a new pillar for sustainability to consolidate the basis and structure of the United Nations’ Sustainable Development Objectives. The use of fundamental concepts is necessary and must be aligned to reassess the results obtained in studies, in comparison with observational data.

Practical implications

The implications arising from the inclusion of health as a fourth pillar of sustainability are diverse. The need to build a new theoretical and conceptual framework for sustainability derives from the fact that health reflects the concern of many postulants in this field of practices. The determining or conditioning conditions of the observed effects of the pandemic by COVID-19, whether situated simply as factors and/or economic, environmental or social reflexes that precede them, requires a conceptual development that allows its approach, as a complex object, whose determinations are subject to variable degrees of uncertainty and diversity.

Originality/value

This study aims to redefine the concept of sustainability, considering that health has become a public health emergency of international interest. Health affects the supply chain, cash flow, interferes with the educational format and interrupts the workforce’s routine, among other aspects, showing the true nature of its importance and its impact in all spheres (economic, environmental and social).

Abstract

Purpose

This research aims to propose the development of a model that identifies, in essential services, the determining factors affecting the technological advances offered by different smart technologies in supermarket retail channels that influence citizens' quality of life, amidst the coronavirus disease 2019 (COVID-19) pandemic.

Design/methodology/approach

The data were collected using a cross-sectional questionnaire survey (n = 469). The authors applied the structural equation modeling (SEM) technique to test the hypotheses, along with the partial least squares (PLS) method for estimating latent variables and combining with the necessary condition analysis (NCA) method.

Findings

According to the results of the NCA method, the results were adequate, and more attention should be paid to the quality of life construct after finding the bottleneck point of 50%. In this sense, adaptive resilience was characterized as the main necessary predictor construct for quality of life. In addition, Generation Z and Millennials have the highest frequency of use in all smart technologies, with “assisted purchase” being the most widely used.

Social implications

Finally, the effect of the pandemic changed the consumption routine with supermarkets, not being a mere option but a necessity in the context of a smart city.

Originality/value

As a result, the proposed model was consistent, showing that all direct and indirect SEM paths were validated, highlighting data security and privacy and resilience issues. In addition, the NCA method complemented the procedures performed in the SEM phase.

Abstract

Purpose

The Covid-19 pandemic has profoundly affected urban communities, generating the need for an immediate response from local governance. The availability of urban data platforms in some smart cities helped the relevant actors to develop various solutions in an innovative and highly contextual way. The purpose of this paper is to explore the role of data platforms in smart cities in the context of the Covid-19 crisis.

Design/methodology/approach

A total of 85 studies were identified using the Clarivate Analytics Web of Science electronic library. After applying exclusion and inclusion criteria, 61 publications were considered appropriate and reasonable for the research, being read in-depth. Finally, only 52 studies presented relevant information for the topic and were synthesized following the defined research questions. During the research, the authors included in the paper other interesting references found in selected articles and important information regarding the role of data in the fight against Covid-19 in smart cities available on the Internet and social media, with the intention to capture both academic and practical perspectives.

Findings

The authors' main conclusion suggests that based on their previous expertise in collecting, processing and analyzing data from multiple sources, some smart cities quickly adapted their data platforms for an efficient response against Covid-19. The results highlight the importance of open data, data sharing, innovative thinking, the collaboration between public and private stakeholders, and the participation of citizens, especially in these difficult times.

Practical implications

The city managers and data operators can use the presented case studies and findings to identify relevant data-driven smart solutions in the fight against Covid-19 or another crisis.

Social implications

The performance of smart cities is a social concern since the population of urban communities is continuously growing. By reviewing the adoption of information technologies-based solutions to improve the quality of citizens' life, the paper emphasizes their potential in societies in which information technology is embedded, especially during a major crisis.

Originality/value

This research re-emphasizes the importance of collecting data in smart cities, the role of the diversity of their sources and the necessity of citizens, companies and government synergetic involvement, especially in a pandemic context. The existence of smart solutions to process and extract information and knowledge from large data sets was essential for many actors involved in smart cities, helping them in the decision-making process. Based on previous expertise, some smart cities quickly adapted their data platforms for an efficient response against Covid-19. The paper analyzes also these success cases that can be considered models to be adopted by other municipalities in similar circumstances.

Abstract

Purpose

A review on additive manufacturing (AM) of shape memory polymer composites (SMPCs) is put forward to highlight the progress made up to date, conduct a critical review and show the limitations and possible improvements in the different research areas within the different AM techniques. The purpose of this study is to identify academic and industrial opportunities.

Design/methodology/approach

This paper introduces the reader to three-dimensional (3 D) and four-dimensional printing of shape memory polymers (SMPs). Specifically, this review centres on manufacturing technologies based on material extrusion, photopolymerization, powder-based and lamination manufacturing processes. AM of SMPC was classified according to the nature of the filler material: particle dispersed, i.e. carbon, metallic and ceramic and long fibre reinforced materials, i.e. carbon fibres. This paper makes a distinction for multi-material printing with SMPs, as multi-functionality and exciting applications can be proposed through this method. Manufacturing strategies and technologies for SMPC are addressed in this review and opportunities in the research are highlighted.

Findings

This paper denotes the existing limitations in the current AM technologies and proposes several directions that will contribute to better use and improvements in the production of additive manufactured SMPC. With advances in AM technologies, gradient changes in material properties can open diverse applications of SMPC. Because of multi-material printing, co-manufacturing sensors to 3D printed smart structures can bring this technology a step closer to obtain full control of the shape memory effect and its characteristics. This paper discusses the novel developments in device and functional part design using SMPC, which should be aided with simple first stage design models followed by complex simulations for iterative and optimized design. A change in paradigm for designing complex structures is still to be made from engineers to exploit the full potential of additive manufactured SMPC structures.

Originality/value

Advances in AM have opened the gateway to the potential design and fabrication of functional parts with SMPs and their composites. There have been many publications and reviews conducted in this area; yet, many mainly focus on SMPs and reserve a small section to SMPC. This paper presents a comprehensive review directed solely on the AM of SMPC while highlighting the research opportunities.

Abstract

Purpose

This study aims to provide an alternative adoption to overcome the energy crisis and environmental effluence by comparative theoretical and trial testing analysis of an innovative combined condenser unit over traditional individual condenser unit water heating systems.

Design/methodology/approach

The presented innovative new unit of the combined condenser heat pipe works efficiently through its improved idea and unique design, providing uniform heating to improve the heat transfer and, finally, the temperature of water increases without enhancing the cost. In this design, all these five evaporator units were connected with a single combined condenser unit in such a manner that after the condensation of heat transfer fluid vapour, it goes equally into the evaporator pipe.

Findings

The maximum temperature of hot water obtained from the combined condenser heating system was 60.6, 55.5 and 50.3°C at a water flow rate of 0.001, 0.002 and 0.003 kg/s, respectively. The first and second law thermodynamic efficiency of the combined condenser heating system were 55.4%, 60.5% and 89.0% and 2.6%, 3.7% and 4.1% at 0.001, 0.002 and 0.003 kg/s of water flow rates, respectively. The combined condenser heat pipe solar evacuated tube heating system promoting progressive performance is considered efficient and environment-friendly compared to the traditional condenser unit water heating system.

Originality/value

Innovative combined condenser heat pipe evacuated tube collector assembly was designed and developed for the study. A comparative theoretical and experimental energy-exergy performance analysis was performed of innovated collective condenser and traditional individual condenser heat pipe water heating system at various mass flow rate.
