Design smart city apps using activity theory.

In this paper we describe an innovative approach to the design process of Smart City interventions. We tested it with participants enrolled in the Master\u2019s Degree program in \u201cInnovators in enterprise and public administration\u201d: the objective of the Master was to stimulate the acquisition of technical and methodological skills useful in designing and implementing specific Smart City actions. During the "project work" phase, participants learned about a design method named SAM \u2013 Smart City Model - based on the Cultural Historical Activity Theory (CHAT). We present an overview of design criteria for Smart City projects, the description of the theoretical framework of Activity Theory, and our proposal of the SAM design model. We also present some examples of student\u2019s \u201cprojects\u201d and a more extensive description of one case study about the full design process of an App planned using SAM, for \u201csmart health\u201d vaccine management and monitoring services. The App was later published and made available to the citizens and was successful in attracting thousands of users. All the participants considered the model very useful in particular because it made possible to understand the interaction and solve contradictions between different stakeholders and systems involved

The Relationship between Buyer and a B2B e-Marketplace: Cooperation Determinants in an Electronic Market Context

In this article, the authors argue that cooperation may be achieved by adding technology dimensions to the core product. Given the growing importance of real time information exchange and interactivity, a better understanding of the use of technology to the establishment and development of the buyer-supplier cooperative relationships is essential for knowledge advancement. Using a sample of nearly 400 SMEs purchasing managers, this paper reveals that in an electronic market context, cooperation is positively affected by termination costs, supplier policies and practices, communication and information exchange, and negatively affected by product prices and opportunistic behavior. Moreover, both relationship commitment and trust play a major role in mediating the relationships between these five determinants and cooperation.relationship marketing, trust, cooperation, electronic markets, e-commerce

Trust and reciprocity effect on electronic word-of-mouth in online review communities

Purpose Social media developments in the last decade have led to the emergence of a new form of word of mouth (WOM) in the digital environment. Electronic word-of-mouth (eWOM) is considered by many scholars and practitioners to be the most influential informal communication mechanism between businesses and potential and actual consumers. The purpose of this paper is to extend knowledge about WOM in this new context by proposing a conceptual framework that enables a better understanding of how trust and reciprocity influence eWOM participation in ORCs. Design/methodology/approach This study applies non-probability convenience sampling technique to conduct a quantitative study of data from an online survey of 189 members of ORCs. Partial least squares (PLS) is used to analyse the correlations between individuals’ intention to seek opinion, to give their own opinion and to pass on the opinion of another within ORCs. Findings The data analysis reveals that opinion seeking within ORCs had a direct effect on opinion giving and opinion passing. Ability trust and integrity trust had a positive effect on opinion seeking, while benevolence trust had a direct positive effect on opinion passing. Reciprocity had a direct impact on opinion passing. While reciprocity did not affect opinion giving, the relationship between these two concepts was mediated by integrity trust. Research limitations/implications By studying the complexities that characterise the relationships between reciprocity, trust and eWOM, the study extends understanding of eWOM in ORCs. Originality/value To the best of the authors’ knowledge, this is one of only a few papers that have examined the complex interrelationships between reciprocity, trust and eWOM in the context of ORCs

The Many Facets of Mediation: A Requirements-driven Approach for Trading-off Mediation Solutions

Mediation aims at enabling dynamic composition of multi- ple components by making them interact successfully in order to satisfy given requirements. Through dynamic composition, software systems can adapt their structure and behaviour in dynamic and heterogeneous envi- ronments such as ubiquitous computing environments. This paper pro- vides a review of existing mediation approaches and their key character- istics and limitations. We claim that only a multifaceted approach that brings together and enhances the solutions of mediation from different perspectives is viable in the long term. We discuss how requirements can help identify synergies and trade-offs between these approaches and drive the selection of the appropriate mediation solution. We also highlight the open issues and future research directions in the area

Trusted operational scenarios - Trust building mechanisms and strategies for electronic marketplaces.

This document presents and describes the trusted operational scenarios, resulting from the research and work carried out in Seamless project. The report presents identified collaboration habits of small and medium enterprises with low e-skills, trust building mechanisms and issues as main enablers of online business relationships on the electronic marketplace, a questionnaire analysis of the level of trust acceptance and necessity of trust building mechanisms, a proposal for the development of different strategies for the different types of trust mechanisms and recommended actions for the SEAMLESS project or other B2B marketplaces.trust building mechanisms, trust, B2B networks, e-marketplaces
