As an increasing number of users have acquired information across the web and mobile platforms for social question and answering (Q&A), it is of interest to explore whether there are differences in social Q&A usages between the two platforms. The purpose of this paper is to compare web and mobile platforms of a social Q&A service from the user’s perspective in terms of three dimensions, namely, demographics, individual-based constructs, and information-based constructs.

Because Zhihu.com is one of the most popular social Q&A sites in China, the authors used online questionnaires to investigate its users’ perceptions of these three dimensions. From January to March 2016, the authors obtained 278 valid responses in total through snowball and convenient sampling. Collected data are analyzed through descriptive statistics and inferential statistics.

The results indicate that there exist significant differences between web users and mobile users on Zhihu.com in terms of gender, affinity, and information seeking. More specifically, compared to the male users, more female users rely on the mobile platform to access the information service; mobile users perceive higher affinity with Zhihu.com than web users; and mobile users perceive higher information-seeking intention than web users do.

Regarding the theoretical aspect, this study proposes a conceptual framework for comparison between the web and mobile platforms of social Q&A from the user’s perspective. Regarding the practical aspect, the comparative results of this study could give social Q&A service providers useful information about users’ differences between web and mobile platforms of social Q&A services.

Disaster risk reduction (DRR) technology sharing has emerged as an important global issue across national boundaries. As a result, the DRR technology-sharing environment needs strengthening based on the findings of difficulties in sharing, investment, and commitment. The purpose of this paper is to three fold: first, it will clarify that a web-based platform is the best conduit for linking DRR technology from the supplier to the beneficiary developing countries. Second, it will find the most evolutionary path based on Korean case studies. Finally, it will make recommendations for the efficient implementation of a web-based platform for DRR technology sharing.

This paper posits that DRR technology sharing is a necessary part of enhancing resilience to disasters in the Asia-Pacific region. The evolution of web-based approaches (a merchandise display-type platform, a journal-type platform, an electronic market-type platform, and an architecture and governance-type platform) and an actual case of space technology sharing providing support for an evolution toward community-based technology sharing in DRR. The research will find the most efficient way going forward based on the case study of a four-year R & D project sponsored by the South Korean Government. It will also find the success factors for the way to establish and operate the platform efficiently and effectively through case studies of the four types of web-based platforms.

Sharing of DRR technology through a web-based platform among Asia-Pacific countries is necessary in order to equip all parties with essential technology to mitigate intensifying disasters, to overcome the barriers of technology sharing, to breakdown transfer issues due to language barriers, and to strengthen insufficient DRR budgets. Among the four types of web-based platforms, the architecture and governance-type platform proved to be the most effective and efficient. In addition, four principles for an efficient implementation are identified through case studies, analysis, and research.

This paper reports on the reasons why it is difficult for DRR technology sharing in the Asia and Pacific regions and suggests a web-based DRR technology-sharing platform as a solution for the region. Moreover, it substantiates that the architecture and governance platform type as the most efficient and effective evolution with four principles: develop based on end-user’s needs; take a problem-solving approach; contain interactive communication tools; and provide business opportunity.

Although many studies show that self-efficacy and continuance intention of Web 2.0 platforms are positively and significant correlated, others reveal some different findings. To clarify this line of research, this study further investigates the effect of self-efficacy on continuance intention and meanwhile examines some moderating variables in this process.

A meta-analysis method was employed to examine the literature containing quantitative measurements of both self-efficacy and continuance intention of Web 2.0 platforms. A total of 31 effects sizes (N = 9,084) were reviewed.

The results indicate medium-sized positive correlation between self-efficacy and continuance intention of Web 2.0 platforms. Further moderation analysis shows that such medium-sized link differed across measures of Web 2.0 platform types, target respondent differences and gender of participants. Specifically, this correlation is largest for transaction-socialization platforms and smallest for experience-socialization platforms. For university-student respondents, the role of self-efficacy in affecting continuance intention is less important than general members of Web 2.0 platforms. Finally, as the percentage of female participants increases, a weaker effect size will be observed.

This study clarifies empirical research regarding users' self-efficacy and their continuance intention. Meanwhile, sources of inter-study variability have been identified by addressing moderator variables in the relationship between self-efficacy and continuance intention of Web 2.0 platforms, which provides directions for future explorations in this area.

This paper aims to present the Modelery, a platform for collaborative repository to support model-based software development. The Modelery is a Web platform, composed both by a Web page and Web services for interoperability.

By performing a study in the existing platforms, it was possible to achieve a set of issues to tackle. The issues enabled the possibility to define a set of requirements that allowed the authors to design a new platform, and to perform a model-driven software development process, which started from the requirements until reaching the final software solution.

With this work, it was possible to perform a survey on the currently available artifacts repositories, categorize them and identify their shortcomings. This was essential to define the set of requirements for a new platform to overcome the identified issues. This process leads to a platform able to improve the currently available solutions, and validated in the scientific community. In this paper, the authors also explore the applications of the repository. First, they use the Modelery to replace an older model’s repository. Second, they have enabled the communication between other tools and the Modelery via Web services.

This work presents a new Web repository for software artifacts aimed at supporting researchers and software developers. The presented platform is an improvement over other platforms on the integration of artifacts repository, social functionalities and scientific publications integration. The authors conclude this paper by comparing the achieved platform in terms of functionalities, against the other analyzed platforms.

The purpose of this study is to explore the antecedents of consumers’ online review intention in e-commerce platforms from a unique perspective of consumer commitment and platform design. Meanwhile, for the dual-platform strategy, i.e. providing both the web and mobile platforms simultaneously, which is widely adopted in the industry but lacks theoretical concerns, this study aims to examine the differences that platform design influences consumer commitment, consequently contributing to online review intention, between the web and mobile contexts.

A cross-sectional online survey is employed, and a structural equation model-based approach is utilized to analyze the data collected from both the website-preferred consumers (N = 167) and the mobile app-preferred consumers (N = 247).

The results indicate that instrumental support design factors and socio-emotional support factors positively influence consumer commitment, which further affect online review intention positively. Furthermore, design factors in different use contexts generate different impacts, and consumer commitment generates a greater effect on online review intention in the mobile than in the web context. Empathy is found to be an important motivator of consumer commitment in both contexts.

To the best of the authors’ knowledge, as one of the first attempts to capture the differences in the relationship between platform design on consumer commitment and online review intention in different use contexts within the dual-platform e-commerce, this study provides insights for e-commerce platform managers and designers to promote consumer commitment and online review engagement by prioritizing the platform design.

Theoretical research was employed to develop a practical approach for applying evolutionary game theory to eWOM marketing controlling strategies modeling via dynamic visualization, systematic simulation experiments.

Evolutionary game theory combined with dynamic simulation modeling can provide a formal approach to understanding web celebrity brand eWOM marketing decision-making in social media, which can thus support the control of unhealthy web celebrity marketing environment. The results demonstrate that the reasonable control of social platform control costs may be more effective than the government policy on web celebrity fake brand eWOM marketing behaviors.

The study enriches the research on the management and control of eWOM marketing as well as provides guidance for the sustainable development of the web celebrity economy in social media.

This paper discusses an ongoing research programme, which explores the development of the software‐as‐a‐service business model by different service providers (xSPs). With the demise of the first phase of the ASP market, due to the failure of vendors to provide business value to potential and existing customers, Web services promise to resolve some of these problems by integrating software applications across heterogeneous technology platforms and business environments. Whether this will be achieved is the subject of continuing debate. This paper presents the preliminary findings from a study, which uses the Microsoft .NET technology platform to develop Web services. Two Web‐enabled prototype databases are discussed. The paper concludes that Web services is still relatively new, but if key technical and business challenges are resolved, it may provide value for the customer where ASPs failed.

The purpose of this paper is to analyse the degree of accessibility of a set of electronic journals that are hosted on widely used online scientific journal publishing platforms and whose content quality has already been certified. Two studies were performed, in which the accessibility of the selected platforms was studied in 2011 and 2016.

The research was performed on publishing platforms than hosted more than 20 journals about human behaviour and factors that may influence it. The evaluation was carried out following the methodology described by the Web Accessibility Initiative in their Website Accessibility Conformance Evaluation Methodology.

The results show that, in spite of an improvement in accessibility, all the analysed electronic consultation platforms contain errors that could hinder their users’ access to their content. The incidence of errors found varies considerably among platforms. As the user interface of each platform analysed is common to all the online scientific electronic journals it hosts, the results obtained are valid for all other journals hosted on a given platform.

Obtained results were valid in the date and time the websites were analysed. Changes made on the websites since then make that the results of an accessibility analysis would be different.

Analysed platforms would require taking steps to ensure their accessibility.

Users with disabilities cannot use these platforms appropriately due to the accessibility problems found. The lack of web accessibility also has implications regarding visibility of published articles and common users.

This work offers a systematic analysis that includes manual accessibility evaluation, which has not been performed in scientific article publishing platforms to the extent presented in this paper. Articles found in the literature perform automatic analyses, which lack the depth of a manual one. Besides, when manual accessibility analysis is performed, usually the home page of a platform or journal alone is considered.

The combination of desalination technology with renewable energy sources (RES) provides a sustainable approach for increasing potable water availability without imposing negative environmental effects. This paper aims to present the development of a platform, which is an internet-based tool integrating the design optimization of desalination systems with spatial modeling based on a geographic information system (GIS).

The proposed platform assists decision-makers to select the optimal location and configuration of both the energy- and water-related subsystems of desalination plants that are power-supplied by RES, such that the lifetime cost of the overall desalination plant is minimized. It enables to optimize the desalination plant site selection and sizing with various hybrid power supply (solar, wind, wave and electrical grid power systems) and desalination technologies combinations, while simultaneously exploiting spatial technologies in an internet-based GIS platform.

A pilot study for the optimal design of stand-alone and grid-connected desalination plants powered by RES is presented, which demonstrates the functionality and features of the proposed platform. It is also shown that a grid-connected desalination plant designed by the proposed software design tool exhibits significantly lower lifetime installation and maintenance costs compared to its stand-alone counterpart.

The proposed platform combines technological, scientific and industrial knowledge with information about societal/political conditions and geo-spatial technologies in a user-friendly graphical interface. Therefore, it provides a design tool enabling its users to secure water supply in a sustainable and economically viable manner.

Members' knowledge is the most important resource in NGOs and it is important to stimulate its exchange. Knowledge that is needed to act in complex situations is hard to exchange, but Web 2.0 technologies provide a toolbox to develop a knowledge management strategy. The paper aims to specify optimal conditions and necessary measures that NGOs should take in order to successfully use Web 2.0 technologies for knowledge exchange.

NGOs and Web 2.0 technologies have specific characteristics in common. It is suggested that these characteristics require certain prerequisites in order to make the use of Web 2.0 technologies successful. Using an iterative and participative design method, a case study is presented that investigated prior boundary conditions and implemented a Web 2.0‐based platform as knowledge management strategy in a large NGO.

NGOs and Web 2.0 are based on strong voluntariness, they are democratic, contribution and personality are strongly tied to each other, and education is rarely formal. Therefore, there is a strong need for contact between members, internal motivation and organizational identification, for quality criteria, for protected spaces and pattern‐structures, if Web 2.0 technologies shall lead to successful knowledge management. The case study demonstrates that considering these circumstances enabled the successful implementation in a large NGO.

The current research helps NGOs to successfully implement Web 2.0 technologies as a means to support knowledge management. A figure with the crucial questions and the means that have to be taken in dependence of the answers is provided.

NGOs do not have the same means to develop formal management strategies as other organizations. Therefore, a thorough understanding of the circumstances that enable knowledge exchange with Web 2.0 technologies is needed. The current research provides information about optimal circumstances and about possibilities to improve less promising circumstances.
