Background: Hundreds of mental health apps are available to the general public. With increasing pressures on care systems, they offer a potential way for people support their and well-being. However, although many highly rated by users, few evidence-based. Equally, our understanding what makes engaging valuable users is limited. Objective: The aim this paper was analyze functionality user opinions mobile purporting cognitive behavioral therapy depression explore key factors that have an...

Community activist groups typically rely on core of highly motivated members. In this paper we consider how crowdsourcing strategies can be used to supplement the activities pro-environmental community activists, thus increasing scalability their campaigns. We focus mobile data collection applications and that engage casual participants in collection. report results a study both quantitative qualitative methods investigate impact different motivational factors strategies, including intrinsic...

Interactive devices and the services they support are reliant on cloud digital infrastructure supporting it. The environmental impacts of this substantial for particular can account up to 85% total impact. In paper, we apply principles Sustainable Interaction Design use infrastructure. We perform a critical analysis current design practice with regard interactive services, which identify as cornucopian paradigm. show how user-centered induce in different ways, combine technical business...

Background Technology can play an important role in supporting mental health. Many studies have explored the effectiveness, acceptability, or context of use different types health technologies. However, existing research has tended to investigate single technology at a time rather than exploring wider ecosystem that people may use. This narrow focus limit our understanding how we could best design Objective The aim this study was which technologies (smartphone apps, discussion forums and...

The substitution of material-based services with digital services—for example films or music—alters the environmental impact our everyday activities and shifts visible material use to less services. A holistic life cycle assessment (LCA) transformation requires information communication technology (ICT) its wide range multifunctional devices as well summation effects caused by new enabled modern ICT. 73rd Discussion Forum on Life Cycle Assessment (DF LCA) was held 21 November 2019 discuss...

Recent research has advocated for a broader conception of evaluation Sustainable HCI (SHCI), using interdisciplinary insights and methods. In this paper, we put into practice to conduct an Interaction Design (SID) digital services. We explore how SID can contribute corporate greenhouse gas (GHG) reduction strategies. show Digital Service Provider (DSP) might incorporate their design process quantitatively evaluate specific intervention by combining user analytics data with environmental life...

In systems composed of multiple autonomous agents, negotiation is a key form interaction that enables groups agents to arrive at mutual agreement regarding some belief, goal or plan, for example. Particularly because the are and cannot be assumed benevolent, must influence others convince them act in certain ways, thus critical managing such inter-agent dependencies. The process may many different forms, as auctions, protocols style contract net, argumentation, but it unclear just how...

If an e-services approach to electronic commerce is become widespread, standardisation of ontologies, message content and protocols will be necessary. In this paper, we present a lifecycle business-to-business e-commerce interaction, show how the Semantic Web can support service description language that used throughout lifecycle. By using DAML, develop sufficiently expressive flexible not only in advertisements, but also matchmaking queries, negotiation proposals agreements. We identify...

Engagement, motivation and active contribution by digital volunteers are key requirements for crowdsourcing citizen science projects. Many systems use competitive elements, example point scoring leaderboards, to achieve these ends. However, while competition may motivate some people, it can have a neutral or demotivating effect on others. In this paper we explore theories of personal social norms investigate normification as an alternative approach engagement, be used alongside instead...

This paper presents a decision theoretic framework that an autonomous agent can use to bid effectively across multiple, simultaneous auctions. Specifically, our enables make rational decisions about purchasing multiple goods from series of auctions operate different protocols (we deal with the English, Dutch, First-Price Sealed Bid and Vickrey cases). The is then used characterize optimal should take. Finally, we develop practical algorithm provides heuristic approximation this ideal.

Summary In this study, we use an improved, more accurate model to analyze the energy footprint of content downloaded from a major online newspaper by means various combinations user devices and access networks. Our results indicate that previous analyses based on average figures for laptops or desktop personal computers predict national global consumption values are unrealistically high. Additionally, identify components contribute most total during stage life cycle digital services. We find...

Summary This article examines the dynamic relationship between consumption of goods and services, technological efficiency, associated resource use, as described by theory Jevons’ Paradox (JP). A is presented about what causes JP, in which efficiency savings are eventually overtaken increases to produce a net increase use therefore environmental impacts. An application was carried out using system dynamics, modeling carbon dioxide equivalent (CO 2 ‐eq) emissions from private road transport...

Abstract There is growing recognition of the value Education for Sustainable Development (ESD) all learners, and unique role that universities play in transformation individuals, institutions societies towards more sustainable futures. Universities engage even lead several areas: education, research community engagement, which are essential this transformation. Further, given their focus influence, pivotal to action needed realise UN Goals (SDGs) but, date, UK university integration ESD...

The purpose of this paper is to discuss ways that a chemistry course could reposition itself by adopting interdisciplinary approaches based on systems thinking and the Sustainable Development Goals (SDGs) as overarching frameworks, give an overview several challenges in higher education facing, how those can be addressed result repositioning. We will discussing need for new type scientist, one who has deep understanding their own discipline but also links with other disciplines equipped...

Over the last few years, electronic auctions have become an increasingly important aspect of e- commerce, both in business to and consumer domains. As a result this, it is often possible find many selling similar goods on web. However, when individual attempting purchase such good, they will usually bid one, or small number, auctions. This results two forms inefficiency. Firstly, may pay more for good than would be expected ideal market. Secondly, some sellers fail make sale that could take...
