Context-awareness has been regarded as an important feature for mobile services. However, only a few services are sensible to context and the features that are context-aware are still limited. Composition of Web services has received much interest in business-to-business or enterprise application, but not so much interest in business-to- consumer applications. This paper presents iCas, a novel architecture that enables the creation of context-aware services on the fly, and discusses its main components. We compare our approach with similar systems and point out the main differences and advantages. To explore context-awareness to support service composition, iCas uses SeCoM, a semantic model to represent context. The main parts of this model are explained as well the advantages of using a semantic model to represent context. We also describe the use of our approach in an university campus to provide pedagogical features and assist the socio-pedagogical interaction of various types of users.

Atualmente, os usuários desejam obter, fornecer, compartilhar e interagir com informações e serviços com conteúdo multimídia em qualquer lugar, a qualquer momento e com qualquer dispositivo. Para que isso seja possível, um dos grandes desafios é assegurar a QoS (Quality of Service) fim a fim (entre o usuário final e a organização provedora de serviço) para a disponibilização de serviços móveis e interativos com conteúdo multimídia para os usuários finais. Em geral esse tipo de serviço têm maior exigência de QoS, pois além dos parâmetros de redes, possuem parâmetros específicos para áudio, imagem e vídeo, além de exigirem sincronização de áudio e vídeo, e a QoS fim a fim deve considerar parâmetros de QoS sob a percepção do usuário final. Com isso, o objetivo deste trabalho é propor um método para o levantamento de parâmetros de QoS para o estabelecimento de USLAs (User Service Level Agreements - Acordo do Nível de Serviço do Usuário) entre a organização provedora de serviço e o usuário final para serviços móveis e interativos com conteúdo multimídia em um ambiente de convergência tecnológica. O método consiste em quatro passos: 1. identificação do serviço a ser oferecido ao usuário final e elaboração de um grafo em árvore...

The increasing usage of mobile technologies for service provision has created the need to understand customer mobile service experiences and to integrate designer’s and technology’s perspectives for the design of successful mobile services. This paper presents the results of a qualitative study with 44 mobile service customers, providing an in-depth understanding of the experience factors that contribute to design improved mobile services. The study results indicate that traditional interface factors, such as usefulness and ease of use, continue to be important. However, the study reveals that contextual factors, such as the social environment and service atmosphere, are very important for the mobile service experience. These results reinforce the need to adopt a broader view of the experience factors for the effective design of mobile services.

Incorporating Mobile service experiences into service design bring new challenges to service innovation and entails a consciousness of service specific characteristics in the mobile context. This is more relevant if we have in mind that these are customer – journeys with self-service situations. This paper presents the results of a quantitative study of mobile service experience. This quantitative study was based on a survey with users of a new mobile service for managing loyalty programs. Study results allow the identification of service experience dimensions. Based on this process a new measurement model is proposed for the customer experience factors and includes them into the design of new services. These results are important to understand the impact of some Mobile Experience factors on experience outcomes such as emotions, sensorial descriptors, attitudes, and social self-concept. Previous literature has conceptualized customer experience but empirical studies are still scarce. Helkkula (2011) charactherizes the service experience’s concept demonstrating the existence of empirical studies only as a outcome based. However, in order to better understand this concept, Verhoef et al. (2009) have developed a conceptual model that reveals the holistic influence of antecedents and moderators in the customer experience. Thus...

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Management from the NOVA – School of Business and Economics; Mobile devices are growing in a popularity way for consumers to access the Internet for mobile services. As the number of mobile devices is multiplying, subscriptions to services through these devices are also expanding. Previous research has found that perceived service value positively mediates the cost/benefit trade-off with behavioural intentions to use mobile services. This research examines the effect of identification with the mobile phone and perceived ubiquity, as possible moderators on the perceived costs/benefits trade-off and perceived mobile service value. A web-survey was conducted using mobile transaction services as illustrative service. The results of the conducted web-survey reveal that perceived ubiquity helps explaining the perceived mobile service value. In contrast to expectations, identification with mobile devices does not make consumers more prone to use mobile services. This study delivered contribution for companies to provide a better understanding of specific drivers and barriers of mobile services to value creation and to help companies effectively allocate their resources to enhance consumer value perceptions.

This study intends to increase understanding of how different types of mobile money services have developed in different environments. For this purpose, two countries were selected, the Republic of Korea and Uganda. From these study cases, some conclusions emerge. The development of mobile banking services can appear at different stages of financial sector development, but it requires a vibrant and competitive telecommunications sector. The regulatory environment does not need to be very sophisticated for the mobile industry to emerge. However, some elements appear to be important. The legal framework should allow (or at least not explicitly forbid) nonbank financial institutions to issue money and use banking agents or correspondents. To ensure wider use of the service by the population, it is important to educate the population on the benefits of mobile money services.

With the cost of mobile phones decreasing steadily, what was once considered a luxury good is now more commonly considered a necessity by many Kenyans, including those at the economic base of the pyramid (BoP). iHub research and research solutions Africa conducted a 6-month study in order to increase the understanding of actual usage of mobile services, products, and applications at the BoP and to understand their potential for economic and social empowerment. The study covered urban and rural areas of 6 districts in Kenya. Its findings are not nationally representative, but comparisons with representative surveys show no significant differences for key indicators, such as phone possession. The added value of the study at hand lies in the qualitative insights on choices, lifestyles, habits and mobile phone usage patterns used among phone owners at the BoP, as well as its focus on add-on services ranging from phone applications to various Internet tools. The overall objective of the study was to provide a thorough and fact-based understanding of the current and potential future demand and usage patterns of the mobile devices by the BoP in Kenya.

Mobile phones are the primary means of accessing information or communicating for those who live at the base of the pyramid (BoP). It is likely that the mobile phone will therefore also be the preferred medium to provide value-added services to those at the BoP, whether they are private users or informal businesses, for the foreseeable future. Although the prepaid mobile model has brought voice and text services to this group, sustainable, replicable models for enhanced services, products and applications are far more limited. The purpose of the study is to investigate the demand for mobile applications, services and products, with a view to increasing economic opportunities and improving well-being for users at the BoP. The key objectives of the study are the following: i) to increase understanding of the actual usage of mobile services, products and applications at the BoP, and to understand their potential for economic and social empowerment; ii) to identify scalable examples of services, products and applications at the concept...

The dynamic growth of mobile communications technology is creating opportunities for economic growth, social empowerment, and grassroots innovation in developing countries. One of the areas with the greatest potential impact is in the contribution that mobile applications can make to agricultural and rural development (ARD), by providing access to information, markets, and services to millions of rural inhabitants. For both agricultural supply and demand, mobile phones can reduce waste, make delivery more efficient, and forge closer links between farmers and consumers. This report provides policymakers and development practitioners with a guide that facilitates the development and deployment of mobile applications for ARD. It also informs their understanding of the key drivers for promoting such applications and services in their countries. Using James Moore’s (1996) revised definition of ecosystems: economic communities based on interacting organizations and individuals the report identifies a wide range of players in the ecosystem for m-ARD apps...

The adoption of mobile services presents enormous opportunities for all stakeholders in the mobile telecommunications industry and society as a whole. This paper uses qualitative evidence to assess the diffusion of mobile services in Australia. Stakeholder and transaction cost economics (TCE) theories are synthesized to provide a guiding framework from which mobile services stakeholders are identified and their interactions described. Interaction conditions, including demand uncertainty, complexity, asset specificity, and frequency, are evaluated in order to provide a diffusion context which enhances our understanding of the transactions that occur among the stakeholders of the mobile industry. We find that while mobile carriers are currently in a dominant position in the industry, in the future, content providers are likely to leverage brand loyalty to become influential stakeholders. This may affect the power balance between them. Both instrumental and normative actions undertaken by Australian stakeholders for the diffusion of mobile services are also evaluated. We find that diverse instrumental actions, such as knowledge building and deployment, subsidy, mobilisation, standard setting, and innovation directive, have been undertaken...

The adoption of mobile services is often studied at a generic level and limited research has addressed personalisation service adoption. This paper proposes a framework for assessing the likely success or failure of personalisation mobile services. It was found that enjoyment and usefulness are the most important factors in attracting users to adopt personalisation services. Comparing these findings with those of similar studies in the literature we suggest that predictors of mobile service adoption may vary depending on the type of services. Furthermore, explanations and predictions based on rational and intuitive models of consumer behaviour in the mobile space may be insufficient and inadequate for determining investments in novel mobile services.; http://aisel.aisnet.org/bled2009/index.html; Sally Rao Hill, Indrit Troshani

The adoption of mobile services is often studied at a generic level and limited research has addressed personalisation mobile services. The purpose of this paper is to develop a model that attempts to predict the adoption of personalisation mobile services amongst young Australians. Employing quantitative empirical evidence, it was found that perceived enjoyment and perceived usefulness are the most important factors in predicting the adoption of these services. These findings provide theoretical and practical implications and insights for the development, design and marketing of personalisation mobile services. Knowledge and appreciation of these factors may help mobile operators and service providers to both design novel personalisation services or enhance existing ones in order to gain competitive advantage.; Sally Rao Hill and Indrit Troshani

While the development of mobile services is experiencing a spectacular growth in many countries worldwide, existing regulatory regimes are ill equipped for dealing with them. In this paper, the authors use qualitative evidence to investigate the manner in which institutional regulatory factors, including legal, societal, and economic factors, can impact mobile services in the Australian mobile telecommunications industry. These factors are important as they shape both the nature of emerging mobile services and their diffusion trajectory. The investigation culminates with an innovative institutional regulatory framework that includes factors such as consumer and intellectual property protection, market and resources access. The authors argue that co-regulation, a mixture of direct monitoring and intervention of regulators through legislation and complete industry self-regulation, is an effective approach for regulating the mobile telecommunications industry. Given the complex and dynamic nature of this industry, co-regulation can minimize monitoring costs and enhance compliance.; Indrit Troshani, Sally Rao Hill

Using qualitative evidence from the Australian mobile telecommunications industry, this study employs social network theory to show how organisational stakeholders can use their salience to affect network interaction dynamics to influence mobile services diffusion. We found that carriers' definitive leverage brand loyalty to become influential stakeholders. Industry associations have ineffectively undertaken diverse mechanisms for achieving power for themselves and mobile end-users while the government regulator has successfully undertaken co-regulation to fulfil its end-user protection objectives. Our analysis explains, at least partially, the limited diffusion of mobile services in Australia.; Indrit Troshani and Sally Rao Hill

This working paper explores strategies to identify and manage potential money laundering (ML) and terrorist financing (TF) risks in mobile financial services (m-FS). Using fieldwork in seven economies as a basis, the paper provides guidance on the best means of assessing perceived versus actual ML and TF risks, and then identifies specific measures to mitigate the actual risks. The paper concludes with recommendations that aim to promote a regulatory balance to foster an enabling environment for business while minimizing ML and TF risks that hinder its sustainability. The paper identifies four risk factors in m-FS and appropriate mitigation responses. The risk factors are anonymity, elusiveness, rapidity, and poor oversight. Anonymity is the risk of not knowing a customer's actual identity, and it can be diminished through enhanced know-your-customer procedures and identification tools. Elusiveness is the ability to disguise mobile transaction totals, origins, and destinations. It can be diminished through transaction limits and enhanced customer profiling...

Access to basic services plays an important role in both individual well-being and a country's economic development. For this reason, general availability of these services to citizens, regardless of income level and geographical location, has generally been viewed as an important public policy goal. However, the precise definition of this goal and the means of attaining it have provoked controversy. This volume explores whether liberalization can contribute to achieving universal service goals and, if so, how, and looks at the types of complementary policies that may be required. It focuses on experience in four sectors: telecommunications, financial, water and sanitation, and energy services. For each sector, an overview paper and one or two case studies from developing countries examine the experience of governments in harnessing liberalization to meet social goals. It is hoped that this cross-sector view will yield general insights which a focus on a single sector may not, and help each sector to generate ideas by drawing upon experience in other sectors. A horizontal assessment also helps to determine how far the services negotiations at the World Trade Organization (WTO)...

Mobile service provisioning is intended to serve interoperable functionality from mobile devices over the network. The mobile service paradigm shifts the role of mobile devices from consumers to providers, opening up new opportunities for a multitude of collaborative services and applications ranging from sharing personal information to collaborative participatory sensing. Although many basic principles of the standard Web service approach continue to apply, the inherent limitations of mobile devices and broadband wireless access render the deployment of standard architectures in mobile environments inefficient. This research introduces two concepts that revolutionize mobile service provisioning: personal and cloud-assisted service provisioning. Personal services are intended to offer a range of user-centric data services to a limited set of consumers that are explicitly authorized by the user providing the service. Personal services facilitate prevailing trends such as social networking and mobile healthcare services, without compromising personal privacy. Cloud-assisted service provisioning bridges the gap between limited resources of mobile devices and increasing resource demands of mobile applications. This approach provides reliable and efficient mobile services...

Mobile communications are permeating virtually every aspect of our lives. The market is experiencing rapid improvements in technologies, while mobile operators are trying to figure out new ways their infrastructures can provide services to the customers. Furthermore, user-innovation with new ways of using these technologies generates powerful feedback loops back into the innovation processes. In this turbulent environment it is difficult to capture and conceptualize how newness comes about and what the main characteristics of innovation are. The aim of this paper is to illustrate how the concept of interactive innovation can be applied to explain the development of mobile services. This study adopts the perspective of the developer rather than the user. Moreover, through the social construction of technology lens, the concepts of sense-making and bricolage are applied to explain the innovation appropriation process during the mobile data value chain improvement process. One of the conclusions drawn is that in the rapidly changing and complex context of mobile services development, the traditional notion of 'interactive innovation' cannot fully explain this phenomenon that takes place.
