With the high penetration rate of the Internet and the prevalence of social networking sites (SNSs), the negative emotions caused by stressors on SNS have become an important issue worthy of attention. This study explored the relationship between SNS stressors, negative emotions and prosocial behavior, by employing negative emotions as the mediation role and social support as the moderator.

The samples of this study were Facebook users who have used it constantly in the past six months. An online survey was conducted, from which 547 responses were completed, and 525 were valid, for an effective recovery ratio of 95.98%.

Employing the structural equation model (SEM), the findings show that five paths were supported with a good fit. Negative emotions (anxiety and loneliness) have a moderating effect.

This study contributes to the literature by factors divided by negative emotions of anxiety and loneliness from SNS stressors’ perspectives. In addition, this study provides additional support the moderating effect of social support of anxiety on prosocial behavior.

The purpose of this study is to reveal the role of individual–social–technology fit in online social network (OSN) value development. The social software features (e.g. communication and interaction), social features (e.g. privacy and trust) and individual features (e.g. sense of belonging and self-disclosure) are considered fitting forms to describe the OSN value. Implications and suggestions are addressed.

The literature review on social software, the social and individual characteristics and the research gap with respect to OSN value is presented. The research arguments are then hypothesized, and research model used to describe the proposed role is examined empirically. The research targeted mobile phone users as the subjects, and the extent of the activities of these users on OSN for both work and studies. A salient investigation explores the moderation effect of gender. The research results are obtained, and the findings are revealed on the basis of 468 social software users.

The significant effect of individual–social–technology fit on OSN value development is presented through the satisfaction of both participation and sharing information, and knowledge about this fit is verified. The interplay of social software, social and individual features contributes significantly to individual–social–technology fit development, implying that OSN value development is not a single issue. OSN value development should be considered concurrently with technological, personal and social issues.

The empirical study confirms that fitness analysis produces a systematic outcome, in which all elements (e.g. social, technology and individual) are required to cooperate with one another to maximize the OSN value. An individual adopts online channels to communicate with others; thus, the benefits may be a multidimensional issue instead of only a single information service issue. They also consider building an equal social relationship to be important, as it enables diverse propositions, maintains acceptable privacy and behaves on faith to enhance the fit of technology features and individual features to value development. The subjects also likely accepted the fact that emotion generation is important for the advantage of fit of technology features and social features, thereby likely benefitting OSN value development.

The OSN does not only add new values to the society but also brings new effects on social development, especially in terms of social cognition from virtual community formation, development and creation. Although existing studies in the literature present the important aspects and antecedents linked significantly to OSN value development, these studies also insufficiently discuss the effect of fit of these facets on OSN value development. This exploratory study mainly aims to propose and examine the individual–social–technology fit model through an empirical investigation. The main argument of the study is that when a positive and healthy virtual society is developed through social software, the individual and social characteristics, as well as the social software features, should be defined with a suitable fit to promote the social networking value.

Recently, the acoustic characteristics of indoor spaces have been perceived to be more important due to the economic development needs of societies. At the same time, container houses have gradually become more widely used in many applications because of their sustainability and ease of use. In spite of their convenience, these container units still need to foster pleasant and quiet sound environments. The paper aims to discuss these issues.

In this paper, commercial software, designed by Ecotect Analysis, has been used to evaluate the sound characteristics of container houses. As a result, the decorated materials in such a small indoor space have been redesigned for the acoustic comfort of users based on the optimal reverberation time (RT). First, a three-dimensional model of the container house was constructed using the software’s default tools. Then, the indoor acoustic characteristics of various design conditions were obtained from the simulation process undertaken.

By comparing the experimental and simulation results, excellent agreement was observed which verified the feasibility of the software. The original container house experienced an RT distribution of 140-315 ms. After selecting a suitable interior design material, its RT distribution was measured at 160-680 ms.

Following the design process described, spatial designers can assess the indoor acoustic characteristics at the concept design stage and ensure that a decent acoustic comfort environment is derived in their building designs. Meanwhile, such modifications should improve the quality of living for residents of container houses and construction cost reductions might be implemented.

This paper aims to develop a curriculum-based virtual and physical mobile (CVPM) learning model, which integrates related physical and e-learning resources associated with elementary school curricula and supports elementary education.

This model provides a highly participative and well-monitored environment with fruitful interactions among students, teachers and museum staff. A practical system was implemented in the National Museum of Natural Science in Taiwan.

The results show that the proposed model can effectively extend related learning resources to satisfy the requirements of elementary education. In addition, this model can engage students’ self-directed explorations through problem-solving learning content during the learning process.

This learning model was implemented in a one-day theme-based learning activity. Generic learning outcomes and qualitative analysis were used to examine the students’ perceptions and the teachers’ feedback of this learning model, respectively.

The results show that both students and teachers highly appreciated this learning model. The model not only strengthens the connection between museum and elementary curricula but also enhances students’ perceptions and positive attitudes toward natural science courses. Finally, this study offers suggestions for future research.

This study develops a CVPM learning model which integrates elementary school courses to satisfy the requirements of elementary education and meet museums’ educational strategies for schools. The practical learning system and services have been successfully implemented and are widely available to elementary schools in Taiwan.
