En la situación actual donde los sistemas TI sanitarios son diversos con modelos que van desde soluciones predominantes, adoptadas y creadas por grandes organizaciones, hasta soluciones a medida desarrolladas por cualquier empresa de la competencia para satisfacer necesidades concretas. Todos estos sistemas se encuentran bajo similares presiones financieras, no sólo de las condiciones económicas mundiales actuales y el aumento de los costes sanitarios, sino también bajo las presiones de una población que ha adoptado los avances tecnológicos actuales, y demanda una atención sanitaria más personalizable a la altura de esos avances tecnológicos que disfruta en otros ámbitos. El objeto es desarrollar un modelo de negocio orientado al soporte del intercambio de información en el ámbito clínico. El objetivo de este modelo de negocio es aumentar la competitividad dentro de este sector sin la necesidad de recurrir a expertos en estándares, proporcionando perfiles técnicos cualificados menos costosos con la ayuda de herramientas que simplifiquen el uso de los estándares de interoperabilidad. Se hará uso de especificaciones abiertas ya existentes como FHIR, que publica documentación y tutoriales bajo licencias abiertas. La principal ventaja que nos encontramos es que ésta especificación presenta un giro en la concepción actual de la disposición de información clínica, vista hasta ahora como especial por el requerimiento de estándares más complejos que solucionen cualquier caso por específico que sea. Ésta especificación permite hacer uso de la información clínica a través de tecnologías web actuales (HTTP, HTML, OAuth2, JSON, XML) que todo el mundo puede usar sin un entrenamiento particular para crear y consumir esta información. Partiendo por tanto de un mercado con una integración de la información casi inexistente, comparada con otros entornos actuales, hará que el gasto en integración clínica aumente dramáticamente, dejando atrás los desafíos técnicos cuyo gasto retrocederá a un segundo plano. El gasto se centrará en las expectativas de lo que se puede obtener en la tendencia actual de la personalización de los datos clínicos de los pacientes, con acceso a los registros de instituciones junto con datos ‘sociales/móviles/big data’.---ABSTRACT---In the current situation IT health systems are diverse, with models varying from predominant solutions adopted and created by large organizations, to ad-hoc solutions developed by any company to meet specific needs. However, all these systems are under similar financial pressures, not only from current global economic conditions and increased health care costs, but also under pressure from a population that has embraced the current technological advances, and demand a more personalized health care, up to those enjoyed by technological advances in other areas. The purpose of this thesis is to develop a business model aimed at the provision of information exchange within the clinical domain. It is intended to increase competitiveness in the health IT sector without the need for experts in standards, providing qualified technical profiles less expensively with the help of tools that simplify the use of interoperability standards. Open specifications, like FHIR, will be used in order to enable interoperability between systems. The main advantage found within FHIR is that introduces a shift in the current conception of available clinical information. So far seen, the clinical information domain IT systems, as a special requirement for more complex standards that address any specific case. This specification allows the use of clinical information through existing web technologies (HTTP, HTML, OAuth2, JSON and XML), which everyone can use with no particular training to create and consume this information. The current situation in the sector is that the integration of information is almost nonexistent, compared to current trends. Spending in IT health systems will increase dramatically within clinical integration for the next years, leaving the technical challenges whose costs will recede into the background. The investment on this area will focus on the expectations of what can be obtained in the current trend of personalization of clinical data of patients with access to records of institutions with ‘social /mobile /big data’.

This Letter addresses image segmentation via a generative model approach. A Bayesian network (BNT) in the space of dyadic wavelet transform coefficients is introduced to model texture images. The model is similar to a Hidden Markov model (HMM), but with non-stationary transitive conditional probability distributions. It is composed of discrete hidden variables and observable Gaussian outputs for wavelet coefficients. In particular, the Gabor wavelet transform is considered. The introduced model is compared with the simplest joint Gaussian probabilistic model for Gabor wavelet coefficients for several textures from the Brodatz album [1]. The comparison is based on cross-validation and includes probabilistic model ensembles instead of single models. In addition, the robustness of the models to cope with additive Gaussian noise is investigated. We further study the feasibility of the introduced generative model for image segmentation in the novelty detection framework [2]. Two examples are considered: (i) sea surface pollution detection from intensity images and (ii) image segmentation of the still images with varying illumination across the scene.

Constructing and executing distributed systems that can adapt to their operating context in order to sustain provided services and the service qualities are complex tasks. Managing adaptation of multiple, interacting services is particularly difficult since these services tend to be distributed across the system, interdependent and sometimes tangled with other services. Furthermore, the exponential growth of the number of potential system configurations derived from the variabilities of each service need to be handled. Current practices of writing low-level reconfiguration scripts as part of the system code to handle run time adaptation are both error prone and time consuming and make adaptive systems difficult to validate and evolve. In this paper, we propose to combine model driven and aspect oriented techniques to better cope with the complexities of adaptive systems construction and execution, and to handle the problem of exponential growth of the number of possible configurations. Combining these techniques allows us to use high level domain abstractions, simplify the representation of variants and limit the problem pertaining to the combinatorial explosion of possible configurations. In our approach we also use models at runtime to generate the adaptation logic by comparing the current configuration of the system to a composed model representing the configuration we want to reach. © 2008 Springer-Verlag Berlin Heidelberg.

Most previous studies of university spinouts (USOs) have focused on what determines their formation from the perspectives of the entrepreneurs or of their parent universities. However, few studies have investigated how these entrepreneurial businesses actually grow and how their business models evolve in the process. This paper examines the evolution of USOs' business models over their different development phases. Using empirical evidence gathered from three comprehensive case studies, we explore how USOs' business models evolve over time, and the implications for the financial sustainability and operational scalability of these ventures. This paper extends existing research on the development of USOs, and highlights three themes for future research.

This study examines the business model complexity of Irish credit unions using a latent class approach to measure structural performance over the period 2002 to 2013. The latent class approach allows the endogenous identification of a multi-class framework for business models based on credit union specific characteristics. The analysis finds a three class system to be appropriate with the multi-class model dependent on three financial viability characteristics. This finding is consistent with the deliberations of the Irish Commission on Credit Unions (2012) which identified complexity and diversity in the business models of Irish credit unions and recommended that such complexity and diversity could not be accommodated within a one size fits all regulatory framework. The analysis also highlights that two of the classes are subject to diseconomies of scale. This may suggest credit unions would benefit from a reduction in scale or perhaps that there is an imbalance in the present change process. Finally, relative performance differences are identified for each class in terms of technical efficiency. This suggests that there is an opportunity for credit unions to improve their performance by using within-class best practice or alternatively by switching to another class.

Physics-based synthesis of tanpura drones requires accurate simulation of stiff, lossy string vibrations while incorporating sustained contact with the bridge and a cotton thread. Several challenges arise from this when seeking efficient and stable algorithms for real-time sound synthesis. The approach proposed here to address these combines modal expansion of the string dynamics with strategic simplifications regarding the string-bridge and string-thread contact, resulting in an efficient and provably stable time-stepping scheme with exact modal parameters. Attention is given also to the physical characterisation of the system, including string damping behaviour, body radiation characteristics, and determination of appropriate contact parameters. Simulation results are presented exemplifying the key features of the model.

The business model of an organization is an important strategic tool for its success, and should therefore be understood by business professionals and information technology professionals. By this context and considering the importance of information technology in contemporary business models, this article aims to verify the use of the business model components in the information technology (IT) projects management process in enterprises. To achieve this goal, this exploratory research has investigated the use of the Business Model concept in the information technology projects management, by a survey applied to 327 professionals from February to April 2012. It was observed that the business model concept, as well as its practices or its blocks, are not so well explored in its whole potential, possibly because it is relatively new. One of the benefits of this conceptual tool is to provide an understanding in terms of the core business for different areas, enabling a higher level of knowledge in terms of the essential activities of the enterprise IT professionals and the business area.

Summary: This is a conceptual paper that aims to identify the key perspectives on business model innovation. Understanding the theoretical and conceptual underpinnings of business model innovation is crucial in facilitating organisation in reinventing their business models. Through a comprehensive literature review, three perspectives are identified. Business model innovation is a complex construct. There is no single approach or method in undertaking business model innovation. Successful undertaking of business model innovation depends on a number of factors. Dynamic capabilities and internal capabilities are just two of many important factors.

This research explores the business model (BM) evolution process of entrepreneurial companies and investigates the relationship between BM evolution and firm performance. Recently, it has been increasingly recognised that the innovative design (and re-design) of BMs is crucial to the performance of entrepreneurial firms, as BM can be associated with superior value creation and competitive advantage. However, there has been limited theoretical and empirical evidence in relation to the micro-mechanisms behind the BM evolution process and the entrepreneurial outcomes of BM evolution. This research seeks to fill this gap by opening up the ‘black box’ of the BM evolution process, exploring the micro-patterns that facilitate the continuous shaping, changing, and renewing of BMs and examining how BM evolutions create and capture value in a dynamic manner. Drawing together the BM and strategic entrepreneurship literature, this research seeks to understand: (1) how and why companies introduce BM innovations and imitations; (2) how BM innovations and imitations interplay as patterns in the BM evolution process; and (3) how BM evolution patterns affect firm performances. This research adopts a longitudinal multiple case study design that focuses on the emerging phenomenon of BM evolution. Twelve entrepreneurial firms in the Chinese Online Group Buying (OGB) industry were selected for their continuous and intensive developments of BMs and their varying success rates in this highly competitive market. Two rounds of data collection were carried out between 2013 and 2014, which generates 31 interviews with founders/co-founders and in total 5,034 pages of data. Following a three-stage research framework, the data analysis begins by mapping the BM evolution process of the twelve companies and classifying the changes in the BMs into innovations and imitations. The second stage focuses down to the BM level, which addresses the BM evolution as a dynamic process by exploring how BM innovations and imitations unfold and interplay over time. The final stage focuses on the firm level, providing theoretical explanations as to the effects of BM evolution patterns on firm performance. This research provides new insights into the nature of BM evolution by elaborating on the missing link between BM dynamics and firm performance. The findings identify four patterns of BM evolution that have different effects on a firm’s short- and long-term performance. This research contributes to the BM literature by presenting what the BM evolution process actually looks like. Moreover, it takes a step towards the process theory of the interplay between BM innovations and imitations, which addresses the role of companies’ actions, and more importantly, reactions to the competitors. Insights are also given into how entrepreneurial companies achieve and sustain value creation and capture by successfully combining the BM evolution patterns. Finally, the findings on BM evolution contributes to the strategic entrepreneurship literature by increasing the understanding of how companies compete in a more dynamic and complex environment. It reveals that, the achievement of superior firm performance is more than a simple question of whether to innovate or imitate, but rather an integration of innovation and imitation strategies over time. This study concludes with a discussion of the findings and their implications for theory and practice.
