College students’ disclosure of location-related information on Facebook

This study drew on existing research and three behavioral intention models to develop the beginning of a new model to explain why college students share their locations on Facebook. Findings showed that students were more likely to disclose their location on Facebook if their friends did so, a concept called subjective norm. Results also showed that subjective norm had an indirect effect on whether people disclosed their location, mediated through people’s attitude toward disclosure, while controlling for usefulness of disclosing. Collectively, this model explained 61% of the variance in why college students share locations on Facebook. Findings are discussed in relation to behavioral-intention models, and practical implications for social media companies are offered.     

Household Adoption of Technology: The Case of High-Speed Broadband Adoption in Australia

Within the home context a high-speed broadband Internet connection is seen as a key enabler for effective access to and use of the Internet. This article examines the factors contributing to household adoption of high speed broadband in Australia. Building on the Theory of Reasoned Action and seminal research on technology adoption in the home and the workplace, the article presents and evaluates a hypothesized model of Household Adoption of Technology.     

Harnessing social dynamics through persuasive technology to promote healthier lifestyle

In light of current calls by medical professionals to confront the global issue of obesity and related illnesses, we developed a mobile application called STEP UP that monitors physical activity and provides data that can be easily shared within a social network. We then conducted an exploratory, theoretical study based on the theory of reasoned action (TRA) followed by an experimental trial and user study. The purpose of the studies was to explore the effect of persuasive technology on physical activity behavior and to investigate its effectiveness in motivating users to use the technology to be more physically active. The application was found to have a positive effect on the participants and their level of physical activity. They enjoyed using the application and were motivated to walk more, especially when enabled to share their step counts with their friends. The social component of the application clearly enhanced users’ walking experience, as the atmosphere of friendly competition motivated them to walk more. Based on user responses, we conclude that a further enhanced application that includes chat functionality may be even more successful in supporting increased physical activity and thus healthier lifestyle.     

3D printing as a means of learning and communication: The 3Ducation project revisited

This research project explores to what extent the utilization of open-source 3D printers and 3D design software could serve as means of learning and communication. The principles of non-formal education aligned with the concept of constructionism are used to create an experimental educational scenario focused on geocultural tourism for persons with visual impairments. This paper documents our experience and presents our findings from a 25-day long project, which took place in Zagori, northwestern Greece. 11 high school students from Portugal designed and manufactured natural and cultural heritage artifacts carrying messages in the Braille language. The objects were then handed to people with visual impairments with a twofold aim. First, to enable the communication among persons with and without visual impairments; and, second, to empower students to participate in training projects through open educational procedures. We conclude that open educational practices can boost students’ active engagement in educational processes. Finally, 3D printing encourages a meaningful communication among people with and without visual impairments via the tangible exploration of geocultural components.     

Web 2.0 applications in the workplace: How to ensure their proper use?

There is an ongoing debate about the role of Web 2.0 applications (e.g., Facebook™ and Instagram™) in the workplace. Indeed, misuse cases of these applications are on the rise and many enterprises still have concerns with their real benefits and values and thus, have been reluctant to adopting them. This paper addresses these concerns by developing restrictions over the social actions that Web 2.0 applications allow users to perform. These restrictions permit to limit for instance, the number of times a social action is performed, the content of a social action, and the recipient of a social action. The restrictions are specified in UML Object Constraint Language and enforced through a run-time monitoring that permits to detect violations. This paper, also, presents an implementation of restrictions over Hangouts™ as an illustrative Web 2.0 application.     

北方地区绿色建筑行动纲要

我国北方地区城市建筑约占全国建筑总量的26%,但建筑能耗却占到全国的40%~50%,因此,北方地区推行绿色建筑对节能减排意义重大。本文从选址与节地、供热计量、绿色建筑激励政策等十个方面阐述北方地区绿色建筑行动纲要。     

Implicit Runge–Kutta methods based on Radau quadrature formula

Using W-transformation of Hairer and Wanner, high-order implicit Runge–Kutta methods based on Radau quadrature are studied. Methods constructed and presented include and extend the existing RadauIA, IB, IIA, IIB type RK methods. 2- and 3-stage general Radau RK methods with two parameters (δ, γ) are constructed. The RK methods with five parameters (α, β, γ, δ, τ), which include both Radau and Lobatto type methods, will be discussed at last.

“灯芯效应”下珊瑚骨料混凝土氯离子传输行为

研究了“灯芯效应”下珊瑚骨料混凝土在Mg²⁺、SO₄^2-共同作用下Cl^-的传输规律，建立了“灯芯效应”下珊瑚骨料混凝土Cl^-传输模型.结果表明：Cl^-沿半浸泡混凝土高度方向由下而上传输的同时也由表层向中心传输，其在混凝土内部的含量呈类抛物面分布；SO₄^2-的存在会加快Cl^-在混凝土中的传输，而Mg²⁺的加入会抑制Cl^-的传输，导致混凝土在相同高度及深度处的Cl^-含量小于SO₄^2-与Cl^-共同作用下的Cl^-含量；本文建立的“灯芯效应”下珊瑚骨料混凝土氯离子传输模型计算结果与实测结果吻合良好.
