Abstract [en]

Software ecosystems (SECOs) and open innovation processes have been claimed as a way forward for the software industry. A proper understanding of requirements is as important for SECOs as for more traditional ones. This article presents a mapping study on the issues of RE and quality aspects in SECOs. Our findings indicate that among the various phases or subtasks of RE, most of the SECO specific research has been accomplished on elicitation, analysis, and modeling. On the other hand, requirement selection, prioritization, verification, and traceability has attracted few published studies. Among the various quality attributes, most of the SECOs research has been performed on security, performance and testability. On the other hand, reliability, safety, maintainability, transparency, usability attracted few published studies. The article provides a review of the academic literature about SECO-related RE activities, modeling approaches, and quality attributes, positions the source publications in a taxonomy of issues and identifies gaps where there has been little research.

Abstract [en]

This article aims to investigate users' continuous usage intention of quick response (QR) code mobile payment services in China. Drawing from UTAUT as theory foundation, this study integrates with literature on perceived risk and involvement to propose a research model and seven research hypotheses to examine user's continuous usage of QR code mobile payment services. The research model was empirically tested with a sample of 215 users of QR code mobile payment services in China. The results indicated that five of seven research hypotheses were significantly supported. According to the results, performance expectancy, effort expectancy and social influence had significant positive direct impacts on users' continuous usage intention of QR code mobile payment services. However, perceived risk did not have a negative effect on users' continuous usage intention of QR code mobile payment services. This article contributes to the existing literature on continuous usage of mobile payment services.

Abstract [en]

Domain Analysis (DA) plays an important role in Model Driven Development (MDD) and Domain-Specific Modeling (DSM). However, most formal DA methods are heavy weight and not practical sometimes. For instance, when computer games are developed, the problem domain (game design) is decided gradually within numerous iterations. It is not practical to fit a heavy-weight DA in such an agile process. In this research, we propose a light-weight DA which can be embedded in the original game development process. The DA process is based on a game ontology which serves for both game design and domain analysis. In this paper, we introduce the ontology and demonstrate how to use it in the domain analysis process. We discuss the quality and evaluate the ontology with a user acceptance survey. The test result shows that most potential users considered the ontology useful and easy to use.

Abstract [en]

Purpose: The purpose of this paper is to investigate the challenges of using ICT in secondary schools in Sweden from teachers' perspectives.

Design/methodology/approach: The research followed a qualitative research approach. First, a conceptual framework was developed based on previous research. Then, four teachers, teaching in six different subjects in secondary schools in Sweden, participated in semi-structured interviews that consisted of open-ended questions exploring their views on the challenges of using ICT in secondary schools.

Findings: According to the results, the authors found that the biggest challenges were associated with the perspective of teaching and teaching preparation. Most challenges from previous research have been re-confirmed by the interviewees in this study. In addition, some new challenges were identified in this study. For instance, the results indicated that it was time consuming to find plagiarism of students' exercises, and there was a lack of ICT training of digital resources provided by the schools.

Originality/value: The investigation of using ICT in secondary schools is of scientific significance because it enriches the understanding of strengths and challenges of using ICT in educational activities. In particular, this research aims to shed light on challenges that teachers may face when using ICT in secondary schools. This research can also contribute to making future strategic plans for the use of ICT in secondary schools.

Abstract [en]

This research examined the adoption of indoor location-based services in Norway. By expanding the Technology Acceptance Model (TAM), a research model, known as the mobile services acceptance model, was used. Based on the research model, seven research hypotheses were presented. The proposed research model and hypotheses were empirically tested using data collected from a survey of users of an indoor location-based service, finding reading rooms, at a Norwegian university. Support was found for five of the seven research hypotheses. Among the factors, the perceived usefulness has the strongest influence on the intention to use. The finding also indicated that trust did not have a direct positive effect on intention to use.

Abstract [en]

Although e-commerce has been adopted and developed rapidly in rural areas in China during the past two years, serious issues have been encountered as well. Practitioners and scientists proposed lists of barriers. However, such lists differ with each other for different regions and at different time. Fixed lists may not help much practically. Present research proposes a framework named N3F4 to structure and formalize such barriers. Based on the framework, researchers could make a list of barriers for a given region, perform surveys among interested people, prioritize the barriers, analyze reasons and propose solutions. In this paper, we introduce the N3F4 framework, and present a case study of applying the framework in one small county in China. The result shows that the N3F4 framework helps structure barriers before performing the survey, and it also helps analyze the result and come up with solutions afterwards, both effectively and efficiently.

Abstract [en]

The development and advancement of ICT enable people to share excess capacity (e.g., car, apartment). In this paper, we focus on Didi Chuxing, which is one of the most prominent examples of car-sharing services in the sharing economy in China. This study aims to investigate the role of trust with car-sharing services in sharing economy from the consumers’ perspective. Based on the literature review, a research model with eight research hypotheses is proposed. The research model is empirically tested with Didi Chuxing by using survey data collected from a sample of 309 subjects. Six research hypotheses are significant supported, while two research hypotheses are rejected in this study. The results indicate that the most important determinant for the consumers’ trust in the car-sharing service platform is platform reputation. In addition, increased degree of the consumers’ familiarity with the car-sharing service platform has a positive impact the consumers’ trust in the car-sharing service platform. However, the perceived car-sharing service platform reputation has a positive impact on the consumers’ trust in drivers on the platform.

Abstract [en]

Today, along with the development of information communication technology, live streaming is getting more and more popular in China. It has established an integrated industrial chain. There are a large number of users watching different live streams (e.g., games. sports, live shows) through personal computers and mobile devices. In this paper, we aim to investigate the values of live game streaming using the Value-Focused Thinking (VFT) approach. We analyze the values of live game streaming from the perspectives of both streamers and spectators. The identified values are represented in the form of a means-ends objective network. The means-ends objective network derived from this research can serve as a conceptual foundation for future studies and provide useful guidelines for practitioners to better operate live game streaming applications.

Abstract [en]

With the development of mobile technology, mobile advertising has become popular worldwide. It seems that almost every user who owns a mobile device receives mobile advertisements from various service providers. However, most consumers hold negative attitudes towards mobile advertising. This research aims to investigate the factors which influence consumers’ adoption of mobile advertising. Based on a literature review from previous research, a research model is proposed. This research model is empirically evaluated using survey data collected from 302 receivers of mobile advertising in China. Consumers’ attitudes toward mobile advertising and incentives explain about 80 percent of consumers’ intention to receive mobile advertisements. In addition, entertainment, credibility, personalization and irritation all have direct effects on consumers’ attitudes toward mobile advertising; the effect of entertainment is quite strong. Both theoretical and practical implications of this research are discussed.

Abstract [en]

MOOC, which stands for massive open online course, has attracted millions of users around the world and it has a promise to be a very important element of future education. However, there is a little research on users' adoption of MOOCs. This paper aims to improve the understanding of users' behaviour intention to use MOOCs. The proposed research model is an extension of technology acceptance model with three factors from the institutional theory. And an empirical study with 279 subjects was conducted to test this model in China. The results indicate that both perceived usefulness and perceived ease of use directly affect users' behaviour intention to use MOOCs significantly. Another interesting finding is that mimetic pressures also have a significant positive influence on users' behaviour intention to use MOOCs.
