The value delivered by these services relies on the quality of their predictions. This paper presents QuPreSS, a general framework which measures predictive service quality and guides the selection of the most accurate predictive service. To do so, services are monitored and their predictions are compared over time by means of forecast verification with observations. A systematic literature review was performed to design a service-oriented framework architecture that fits into the current body of knowledge. The service-oriented nature of the framework makes it extensible and interoperable, being able to integrate existing services regardless their heterogeneity of platforms and languages. Finally, we also present an instantiation of the generic framework architecture for the weather forecast domain, freely available at http://gessi.lsi.upc. edu/qupress/ Thu, 16 May 2013 08:35:17 GMT http://hdl.handle.net/2117/19273 2013-05-16T08:35:17Z Martínez Fernández, Silverio Juan; Bisbal Riera, Jesús; Franch Gutiérrez, Javier no Body of knowledge, Forecast verifications, Framework architecture, Generic frameworks, Service Oriented, Service Quality, Services quality, Stock market, Systematic literature review, Weather forecasts Nowadays there are lots of predictive services for several domains such as stock market and bookmakers.

Different designs support some quality attributes while damaging others; therefore, trade-off analysis is needed to make informed decisions. Moreover, analysis made in theory needs to be complemented with observations in practice, especially when using a particular set of technologies to implement the system. In this paper, we present a particular instance of this problem. We study how the Three-Layer architectural pattern may be developed using plug-ins. We compare two extreme alternatives according to several representative scenarios and their impact in some quality attributes. Then, we apply this theoretical knowledge to a case study, the implementation of a plug-in-based tool for managing architectural knowledge using Eclipse. We report some unexpected difficulties found that forced us to adapt the theoretical solution into an operative architecture.

These LMSs were designed and developed for users accessing the system through web browsers on desktop computers or laptops. However, over the last years, an increasing percentage of the registered accesses to various LMS platforms have been from mobile devices such as smartphones. While tackling the problems arising through the design of a mobile client for the Open Source LMS Moodle called Moodbile, the question of how to decide which services of Moodle could be accessed from smartphones became very relevant. This paper presents a data analysis study conducted on the Moodle server logs of the Universitat Politècnica de Catalunya-Barcelona Tech (UPC) virtual campus, Atenea, and the insight gained regarding the particular characteristics of the accesses from mobile devices. The main achievement of this study is that it provides insight of the use of the university LMS from mobile devices.

Such systems are implemented in very different programming languages, using distinct types of resources, etc. Learning and Teaching is one of those application areas, where there are different learning platforms, repositories, tools, types of content, etc. These systems should interoperate among them to provide better and more useful learning services to students and teachers, and to do so web services and interoperability specifications are needed. This paper presents a service-based framework approach to facilitate the interoperability between Learning Management Systems and Personal Learning Environments, which has been implemented as a proof of concept and evaluated through several pilot experiences. From such experiences it is possible to see that interoperability among the personal and institutional environments it is possible and, in this way, learners can learn independently without accessing to the institutional site and teachers have information about learning that happens in informal activities.

These instruments evolve and change, what means that learning activities are being influenced depending of the context that surrounds the educational processes. The Information and Communication Technologies application to teaching and learning processes implies a revolution regarding to the way learning and teaching is performed. However this model did not provide as many advantages as it were supposed to and a new change is necessary. Against this background rise web 2.0 tools and tendencies, which is another evolution on the way learners and teachers interact but those tools should be incorporated and adapted to the existing systems. This is not an easy task and means to take into account the users, the tools, the interoperability between learning tools, etc. Along this paper the problem of how to integrate 2.0 tools into institutional learning system is explored, specially focused on how through PLE and by using interoperability solutions it is possible to take advantage of 2.0 tools in learning and teaching processes. It is proposed a simply way to integrate such tools with the existing systems and an experience that demonstrate how to apply it. This experience is based on the use of twitter in a classroom. From that experience can be shown that the integration of 2.0 tools is not complex and improves students’ participation and motivation, which could have associated a learning improvement.

However, derived from a recent analysis of the area and from many definitions used in literature, we think that there is not a clear understanding of what should be considered as a SCM system. In the same way, the minimal functional requirements for a system to be considered as an SCM information system are not yet clear. This contrasts with the existence of SCOR, a much publicised model used as standard in the SCM domain. Although SCOR does not include a definition for an SCM information system and, in fact, it leaves the system implementation at will of the companies, we think that it can be used to provide a better definition. Thus, in the present work we intent to offer a tentative definition of SCM systems based on SCOR.

Many authors have made individual proposals of interesting topics to be researched around CRM systems, but no overarching research agenda has yet been proposed. Based upon a recent research literature review that we have undertaken, which includes several real case studies conducted in order to learn from CRM experience within specific companies and industries, we propose and detail what appears to be a natural CRM Systems Life-cycle. Although a more focussed cycle has been mentioned for CRM systems implementations, we propose and define in detail a CRM Systems Life-cycle which covers other phases preceding and following implementation. We believe that such a well-defined cycle may help in future proposals of research agendas around CRM systems, as well as in the contextualization of more specific research themes.

In this paper we present the few we have discovered references while deriving and expanding some analysis from them. The sparse results of this analysis are then summarized and classified. This situation contrasts with the clear importance of PA as an IS consumer and often as a change leader in IS management practices, which is also depicted in the paper. As an example of what future research questions could be posed and of what findings could be expected from this research domain, we present a real IS outsourcing case of study which appears to be rather original in the approach taken by the involved PA. Hence, with all the issues outlined in this preliminary research work, we believe that it is possible to justify an interest in researching this topic and to encourage new scientific activities resulting from it, such as new proposals for PA of specific IS outsourcing frameworks, methods or in-depth case studies like the one introduced here.

However, sometimes a compensation is not essential. Hence, diagnosing and compensating each and every one of their failures may be ineffective. Rather than polluting a requirements specification with fine grained definition of failure-handling conditions, this work aims to increase the flexibility of failure handling in self-adaptive systems using tolerance policies. We allow the expression of conditions in which certain failures may be ignored – i.e., conditions on which a failure will not be compensated. Such policies may lead to reduced costs and performance improvement. The FAST framework consists of the definition of a tolerance policy, the mechanisms to evaluate this policy and a tool to aid the creation of policies.

Different reference architectures and systematic approaches have been proposed to address this challenge. Several of these approaches are based on goal models, given their suitability to express and reason on alternative behaviors. In this paper we intend to provide a basis for comparing architectures described in goal-based models in regard to their adaptability. This way, different approaches to improve adaptability may be compared based on the resulting architectures. To do so we mapped two adaptability metrics onto i* models and developed guidelines to define the adaptability of individual elements, based on the extra information provided by i* models. We applied these metrics in a healthcare system to illustrate the comparison of architectures.
