Abstract

Purpose

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/methodology/approach

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

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.

Research limitations/implications

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

Practical implications

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.

Social implications

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.

Originality/value

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.

Abstract

Purpose — To provide a theoretical background to understand current local search engines as an aspect of specialized search, and understand the data sources and used technologies.

Design/methodology/approach — Selected local search engines are examined and compared toward their use of geographic information retrieval (GIR) technologies, data sources, available entity information, processing, and interfaces. An introduction to the field of GIR is given and its use in the selected systems is discussed.

Findings — All selected commercial local search engines utilize GIR technology in varying degrees for information preparation and presentation. It is also starting to be used in regular Web search. However, major differences can be found between the different search engines.

Research limitations/implications — This study is not exhaustive and only uses informal comparisons without definitive ranking. Due to the unavailability of hard data, informed guesses were made based on available public interfaces and literature.

Practical implications — A source of background information for understanding the results of local search engines, their provenance, and their potential.

Originality/value — An overview of GIR technology in the context of commercial search engines integrates research efforts and commercial systems and helps to understand both sides better.

Abstract

Purpose — The purpose of this chapter is to give an overview of the context of Web search and search engine related research, as well as to introduce the reader to the sections and chapters of the book.

Methodology/approach — We review literature dealing with various aspects of search engines, with special emphasis on emerging areas of Web searching, search engine evaluation going beyond traditional methods and new perspectives on Web searching.

Findings — The approaches to studying Web search engines are manifold. Given the importance of Web search engines for knowledge acquisition, research from different perspectives needs to be integrated into a more cohesive perspective.

Research limitations/implications — The chapter suggests a basis for research in the field and also introduces further research directions.

Originality/value of paper — The chapter gives a concise overview of the topics dealt within the book and also shows directions for researchers interested in Web search engines.

Abstract

Purpose

Due to the “European Union Framework Directive on Safety and Health at work” (Directive 89/391/EEC, 1989), every employer is obliged to avoid psychosocial hazards when designing work. Little is known empirically about the barriers that workplace actors experience while developing and implementing OSH measures that prevent psychosocial hazards. The purpose of this paper is to explore barriers, causes and attempts to overcome them and discusses them with reference to relevant theoretical concepts and models that help to explain how these barriers hinder the development and implementation of OSH measures.

Design/methodology/approach

Semi-structured interviews with workplace actors in charge of psychosocial risk assessment (PRA) were conducted in 41 business cases, and transcripts were analysed using a thematic analysis approach. Barriers, causes and attempts to overcome them were extracted inductively and discussed with reference to relevant theories and explanatory models.

Findings

The complex nature of psychosocial risks, hindering general beliefs, lack of a perceived scope for risk avoidance, lack of assumptions of responsibility among players on all hierarchical levels, discrepancies between formal responsibility and decision authority, and low reflexivity on processes of development and implementation of interventions were described as barriers. Causes and attempts to overcome these barriers were reflected upon by workplace actors.

Practical implications

Recommendations on the organisation of PRA will be given with respect to the reported results and relevant research in this field.

Originality/value

This qualitative study explores the barriers to developing and implementing OSH measures to eliminate psychosocial hazards, from the perspective of actors in charge of PRA, and why they might fail.

Abstract

Purpose

The purpose of this paper is to provide empirical evidence on the motivation of supporters to contribute resources to reward-based crowdfunding campaigns.

Design/methodology/approach

The paper reports results from a survey combining open and closed questions, addressing supporters of reward-based crowdfunding campaigns in the field of video game development. Publicly available data from a large crowdfunding website complements the approach.

Findings

Two groups of supporters emerge from the data: one group derives motivation almost exclusively from a purchasing motive, the other group displays the purchasing motive alongside an altruistic and involvement motive. There is little indication that social acknowledgement plays a role for supporter motivation. Supporters rely on the evaluation of previous activities of an entrepreneur to judge trustworthiness.

Originality/value

The manuscript offers empirical insights into the previously scarcely researched question why supporters contribute to reward-based crowdfunding. These insights inform research on reward-based crowdfunding and help entrepreneurs considering reward-based crowdfunding as a way to fund entrepreneurial activities.
