The purpose of this paper is to study the unexpected consequences in the operation of urban environments. Prediction within the urban planning process often presents difficulties and unintended consequences. It is not enough to develop a good project. Unexpected consequences are possible because of the environment. The authors argue that these problems of uncertainty can be minimized with citizen participation and the use of new technologies.

The problem of how urban planning initiatives result in unexpected consequences is described. These effects are determined by studying a series of cities and real urban environments. A case study on urban accessibility is developed for a better understanding of the problem.

Avoiding unexpected consequences in the operation of urban environments is strongly linked to the concept of Smart City 3.0. This concept is based on the co-creation. In this line to address the problem, a citizen-centric methodology using the latest information and communications technologies and internet of things technologies is presented. As a practical application, different categories of unexpected events related to the Faculty of Education building at the University of Alicante have been identified as a consequence of the impact of its environment. An uncomfortable or non-accessible environment causes unforeseen behaviour of individuals.

There are no analytical tools to investigate how aspects of the urban environment cause uncertainty about the acceptance of projects by future citizen users. This work takes a step forward in that direction.

The purpose of this paper is to discuss unmanned aerial vehicle (UAV) and the comparison of image processing software.

Images from a drone are used and processed with new digital image processing software, Imagine UAV^® of Erdas imagine 2015^®. The products (Digital Surface Model and ortho images) are validated with check points (CPs) measured in the field with Global Positioning System. Moreover, similar products are produced by Agisoft PhotoScan^® software and are compared with both the products of Imagine UAV and the CPs.

The results reveal that the two software tools are almost equivalent, while the accuracies of their products are similar to the accuracies of the external orientations of drone images.

Comparison of image processing software.

Sustainable customer relationship management (SCRM) is a combination of business strategy, customer-oriented business processes and computer systems that seeks to integrate sustainability into customer relationship management. The purpose of this paper is to contribute to the body of knowledge of marketing, business management and computer systems research domains by classifying in research categories the current state of knowledge on SCRM, by analysing the major research streams and by identifying a future research agenda in each research category.

To identify, select, collect, synthesise, analyse and evaluate all research published on SCRM, providing a complete insight in this research area, the PRISMA methodology, content analysis and bibliometric tools are used.

In total, 139 papers were analysed to assess the trend of the number of papers published and the number of citations of these papers; to identify the top contributing countries, authors, institutions and sources; to reveal the findings of the major research streams; to develop a classification framework composed by seven research categories (CRM as a key factor for enterprise sustainability, SCRM frameworks, SCRM computer tools and methods, case studies, SCRM and sustainable supply chain management, sustainable marketing and knowledge management) in which academics could expand SCRM research; and to establish future research challenges.

This paper have an important positive social and environmental impact for society because it will lead to an increase in the number of green and socially conscious customers with an ethical behavior, while also transforming business processes, products and services, making them more sustainable.

Customer relationship management in the age of sustainable development is an increasing research area. Nevertheless, to the authors' knowledge, there are no systematic literature reviews that identify the major research streams, develop a classification framework, analyse the evolution in this research field and propose a future research agenda.

Electric mobility as a service (eMaaS) is suggested as a possible solution to ease transportation and lessen environmental issues by providing a collaborative transport sharing infrastructure that is based on electric vehicles (EVs) such as electric cars, electric bicycles and so on. Accordingly, this study aims to propose a multi-tier architecture to support the collection, processing, analytics and usage of mobility data in providing eMaaS within smart cities. The architecture uses application programming interfaces to enable interoperability between different infrastructures required for eMaaS and allow multiple partners to exchange and share data for making decision regarding electric mobility services.

Design science methodology based on a case study by interview was used to collect data from an infrastructure company in Norway to verify the applicability of the proposed multi-tier architecture.

Findings suggest that the architecture offers an approach for collecting, aggregating, processing and provisioning of data originating from sources to improve electric mobility in smart cities. More importantly, findings from this study provide guidance for municipalities and policymakers in improving electric mobility services. Moreover, the author’s findings provide a practical data-driven mobility use case that can be used by transport companies in deploying eMaaS in smart cities.

Data was collected from a single company in Norway, hence, it is required to further verify the architecture with data collected from other companies.

eMaaS operates on heterogeneous data, which are generated from EVs and used by citizens and stakeholders such as city administration, municipality transport providers, charging station providers and so on. Therefore, the proposed architecture enables the sharing and usage of generated data as openly available data to be used in creating value-added services to improve citizen’s quality of life and viability of businesses.

This study proposes the deployment of electric mobility to address increased usage of vehicles, which contributes to pollution of the environment that has a serious effect on citizen’s quality of life.

This study proposes a multi-tier architecture that stores, processes, analyze and provides data and related services to improve electric mobility within smart cities. The multi-tier architecture aims to support and increase eMaaS operation of EVs toward improving transportation services for city transport operators and citizens for sustainable transport and mobility system.

Religious tourism is a form of tourism where people of a particular faith travel to visit places of religious significance in their faith. Previous research into the various aspects of religious and spiritual tourism (RST) has been noticeably extended. The purpose of this study is to perform systematic mapping to provide trends and classification regarding the recent publications in the area of RST.

This study collected 181 papers from five scientific databases, from which 122 were selected to be classified according to six properties: research type, research focus, research method, investigated religion, publication type and time.

The analysis of these data resulted in a map of the research field, which was presented under three perspectives: the distribution and trends over time of each classification property and the relationship between them. Besides the visual map, the full list of classified papers is available. The results showed that the number of publications is increasing every year, which shows a growing interest in this field. Moreover, the primary research focuses were destination, demand and marketing. Top three journals were found to be International Journal of Tourism Research, Tourism Recreation Research and Journal of Heritage Tourism. Furthermore, evaluation research, solution proposals and opinion papers were the main research types in the area. In addition, the majority of studies focused on Christianity and Islam. Finally, survey, discussion paper, interview and case study were the predominantly used research methods.

The mapping study delivers the first systematic summary of RST research.
