Purpose – A large variety of online communities have emerged during the last years as a result of the challenges faced by both the business and scientific worlds. This trend has also been promoted by the development of internet and new Web 2.0 technologies. In this context, this paper is focused on the determinants of success of online communities. But, as a difference from other studies, these determinants are analyzed from the social network analysis perspective. Several constructs related to the community organization as a social network are proposed and their interrelations are hypothesized in a general research framework. The obtained results test the proposed model providing the most relevant antecedents of the project success. Design/methodology/approach – A case study based on Linux ports to non-conventional processor and environments is used to test the proposed model. Structural equation modeling analysis is used to validate the structural proposed model. Findings – The main antecedents of online communities’ success, quantifying the strength of the relation through the standardized path coefficients. Research limitations/implications – The research is limited to a particular set of online communities engaged with the development of the non-conventional Linux ports. However, they constitute a representative set of communities in the field of the open source projects (OSS) development, which are typically developed using a community of support. Originality/value – This paper fulfils the main antecedents causing the successful development of Internet virtual communities. Instead of using sources of data coming from users’ surveys, this study employs community interactions as a source of data. Results have important implications over the development of online communities, like software business models based on virtual communities and open source software
An evolutionary factor analysis computation for mining website structures

This paper explores website link structure considering websites as interconnected graphs and analyzing their features as a social network. Two networks have been extracted for representing websites: a domain network containing subdomains or external domains linked through the website and a page network containing webpages browsed from the root domain. Factor analysis provides the statistical methodology to adequately extract the main website profiles in terms of their internal structure. However, due to the large number of indicators, the task of selecting a representative subset of indicators becomes unaffordable. A genetic search of an optimum subset of indicators is proposed in this paper, selecting a multiobjective fitness function based on factor analysis results. The optimum solution provides a coherent and relevant categorization of website profiles, and highlights the possibilities of genetic algorithms as a tool for discovering new knowledge in the field of web mining
Analysis of virtual communities supporting OSS projects using social network analysis
(2010) Toral, S. L.; Martínez Torres, María del Rocío; Barrero, Federico; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Universidad de Sevilla.

This paper analyses the behaviour of virtual communities for Open Source Software (OSS) projects. The development of OSS projects relies on virtual communities, which are built on relationships among members, being their final objective sharing knowledge and improving the underlying project. This study addresses the interactive collaboration in these kinds of communities applying social network analysis (SNA). In particular, SNA techniques will be used to identify those members playing a middle-man role among other community members. Results will illustrate the importance of this role to achieve successful virtual communities
Current paradigms in intelligent transportation systems
(2010) Toral, S. L.; Martínez Torres, María del Rocío; Barrero, Federico; Arahal, Manuel R.; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Universidad de Sevilla.

Intelligent transportation systems (ITS) constitute today a multidisciplinary field of study involving a large number of different research areas. As a consequence, it is difficult to achieve a structured view of ITS, which is necessary to unify efforts and as guidance for future developments. This study aims to identify the main paradigms in the field of ITS by semantically analysing studies related to this general topic. An understanding about which research is considered valuable by the research community to build upon may provide valuable insights in this field. As a result of the statistical treatment of data, up to 13 paradigms are obtained. The scope of these paradigms and the relationships between them have also been detailed, providing a structured vision of ITS synthesised in a map form

Diferencias de género en las universidades españolas y en sus órganos gerenciales
(Universidad del Zulia, 2014) López-Bonilla, Jesús Manuel; Martínez Torres, María del Rocío; Díaz Fernández, María del Carmen; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Educación y Ciencia (MEC). España
Las universidades españolas son un reflejo de las desigualdades de género en la esfera pública. Diversos trabajos e informes publicados hasta la fecha muestran la falta de equidad en la participación de mujeres y hombres en las instituciones consideradas como democráticas. El objetivo principal de este trabajo es diagnosticar la composición de género en el ámbito de la gerencia universitaria española. Así, se analiza la presencia de la mujer en la universidad española, su representación en los órganos de gobierno y la evolución de estas cifras en los últimos años. Para ello, en primer lugar se revisa la normativa en materia de igualdad de género, tanto a nivel nacional como europeo y, en segundo lugar, se realiza un análisis longitudinal para abordar la situación de las mujeres y los hombres en las universidades españolas, tanto públicas como privadas. La investigación se cataloga como descriptiva. Los resultados reflejan una aparente tendencia a la igualdad formal en el acceso discente y docente a la universidad, pero esconde una segregación que sigue manteniendo a las mujeres en situaciones de desigualdad ante los hombres
How can managers in the hospital in the home units help to balance technology and physician – patient knowledge?
(Oxford University Press, 2011) Cepeda-Carrión, Gabriel; Cegarra-Navarro, Juan Gabriel; Martínez Caro, Eva; Eldridge, Stephen; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Educación y Ciencia (MEC). España
Background. With the passing of time, knowledge like other resources can become obsolete. Thus, people in a healthcare system need to update their knowledge in order to keep pace with the ongoing changes in their operational environment. Information technology continually provides a great amount of new knowledge which can lead to healthcare professionals becoming overloaded with knowledge. This overloading can be alleviated by a process of unlearning which enables the pro- fessional to retain just the relevant and critical knowledge required to improve the quality of service provided by them. Objective. This paper shows some of the tools and methods that Hospital-in-the-Home Units (HHUs) have used to update the physician–patient knowledge and the technology knowledge of the HHUs’ personnel. Design. A survey study was carried out in the HHU in Spanish health system in 2010. Setting. Fifty-five doctors and 62 nurses belonging to 44 HHUs. Interventions. None. Results. Three hypotheses are presented and supported, which suggest that technology and physician–patient knowledge is related to the unlearning context and the unlearning context impacts positively on the quality of health services provided. Conclusion. The key benefits of the unlearning context for the quality of service provided in HHUs are clear: it enables them to identify and replace poor practices and also avoids the reinventi on of the wheel (e.g.: by minimizing unnecessary work caused by the use of poor methods) and it reduces costs through better produ ctivity and efficiency (improving services to patients)
Identification of new added value services on intelligent transportation systems
(2013) Martínez Torres, María del Rocío; Díaz Fernández, María del Carmen; Toral, S. L.; Barrero, Federico; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Universidad de Sevilla.

The evolution of electronics and the growing capabilities of in-vehicle and public infrastructure equipment make feasible the development of new value-added services in the field of intelligent transportation systems (ITS). However, initiatives in this sense frequently failed due to the lack of agreement or coordination among service providers, public authorities and final users. This article proposes a scientific method based on concept mapping techniques to extract these value-added services. The main benefit of the proposed methodology is its ability to take into account the different points of view of the main actors involved in the transportation field. Obtained results will provide the general guidelines for future ITS services
Implementing telemedicine technologies through an unlearning context in a homecare setting
(Taylor & Francis, 2013) Cegarra-Navarro, Juan Gabriel; Cepeda-Carrión, Gabriel; Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Educación y Ciencia (MEC). España; Junta de Andalucía
Despite the opportunities the health sector will offer as a result of the design and development of a technology infrastructure, the fact is that hospitals have been slow to adopt telemedicine technologies, largely because very few organisations are prepared to face this challenge. A possible explanation for the efficiency and effectiveness gaps of services provided by Hospital-in-the-Home Units (HHUs) may relate to the advantages and disadvantages of the knowledge processes that these units exhibit as a result of their different structural properties. This paper investigates the approaches that HHUs have used to update the knowledge of physicians and their members' knowledge of technology, and relates them to an unlearning context (UC) and improvement in the quality of health services. These relationships are examined through an empirical investigation of 55 doctors and 62 nurses belonging to 44 HHUs. The research findings suggest that the key benefits of a UC in HHUs are clear. It enables them to identify and replace poor practices and also avoids the reinvention of the wheel; it enables cost reduction by minimising unnecessary work caused by the use of poor methods and it enables improvements adopting new telemedicine technologies.
Improving the absorptive capacity through unlearning context: an empirical investigation in hospital-in-the-home units
(Taylor & Francis, 2012) Cepeda-Carrión, Gabriel; Cegarra-Navarro, Juan Gabriel; Martínez-Caro, Eva; Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Educación y Ciencia (MEC). España
The Spanish healthcare system has undergone important changes, particularly in the development of new homecare services. In practice, however, results have been mixed. Some homecare services have been successful, but implementation failures are common and the intended patients are frequently reluctant to use the homecare services. A possible explanation for efficiency and effectiveness gaps of services provided by hospital-in-the-home units (HHUs) may relate to the advantages and disadvantages of the knowledge processes that these units highlight as a result of their different structural properties. This study examines the impact of an unlearning (forgetting) context on the HHU's ability to challenge basic beliefs and to implement processes that are explicitly or tacitly helpful in the reception of new ideas (absorptive capacity). These relationships are examined through an empirical investigation of 54 doctors and 62 nurses belonging to 44 HHUs. The results show that the unlearning context plays a key role in managing the tension between potential absorptive capacity and realized absorptive capacity.
Modelling mailing list behaviour in open source projects: the case of ARM embedded Linux
(2009) Toral, S. L.; Martínez Torres, María del Rocío; Barrero, Federico; Universidad de Sevilla.

One of the benefits firms can derive from using Open Source Software (OSS) is informal development collaboration, and the primary tool for collaboration and coordination are group mailing lists. The purpose of the paper is modelling mailing lists behaviour in OSS projects, using a set of descriptors that could inform about their quality and their evolution. As a case study, a mailing list focused on ARM embedded Linux has been selected. Messages posted to this list from 2001 to 2006 have been extracted, and factor analysis has been applied to obtain the underlying patterns of behaviours. Theory about communities of practice has been used to understand the meaning of the extracted patterns. Their time distribution is finally described. The paper provides new insights into the behaviour of mailing list as a source of support for OSS projects and highlights the importance of an involved core of individuals inside the community

Purpose – The Internet has evolved, prompted in part by new Web 2.0 technologies, to become a more widespread platform for interaction, communication, and activism. Virtual communities, or groups of people informally bound together by shared expertise, synthesise this Internet evolution and theWeb 2.0 technology. Users increasingly want to engage online with one another and with organisations of all kinds. These novel Internet-based technologies dominate the new business models of the digital economy giving companies radical new ways to harvest the talents of innovators working outside corporate boundaries. One of the most illustrative examples of this new trend is the Open Source Software (OSS) projects development. This paper aims to analyse the structure and topology of the virtual community supporting one of the most successfully OSS projects, Linux. The objective is to provide conclusions for being successful in the development of future virtual communities. As companies learn to manage these virtual communities, they will develop smarter and faster ways to create value through them. Design/methodology/approach – The interactions of the virtual community members of an ARM-embedded Linux project website is analysed through social network analysis techniques. The participants’ activity is studied and some conclusions about the participation features are obtained using the Gini coefficient. In particular, a participation inequality behaviour or a concentration on a small number of developers is clearly observed. Findings – The paper deals with the guidelines that virtual communities should follow to be successful. Results about the structure of a successful virtual community and its time evolution are provided to determine the mentioned guidelines. Research limitations/implications – The research is limited to a particular virtual community engaged with the development of the ARM-embedded Linux OSS. Other successful virtual communities can be analysed, and the conclusions could be compared. Anyway, the proposed analysis methodology can be extended to other virtual communities. Originality/value – The paper fulfils the development and features of Internet virtual communities to be successful. Results have important implications over the development of new software business models based on virtual communities and open source software. Contributions about the best organisation of virtual communities leading to a successful development of the underlying project are presented.
Virtual communities as a resource for the development of OSS projects: the case of Linux ports to embedded processors
(2009) Toral, S. L.; Martínez Torres, María del Rocío; Barrero, Federico; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Universidad de Sevilla. Departamento de Ingeniería Electrónica; Ministerio de Educación y Ciencia (MEC). España; Junta de Andalucía
Open source software (OSS) projects represent a new paradigm of software creation and development based on hundreds or even thousands of developers and users organised in the form of a virtual community. The success of an OSS project is closely linked to the successful organisation and development of the virtual community of support. The main objective of this article is to analyse the activity of virtual communities. Social network analysis is employed to analyse Linux ports to embedded processors as a case study to achieve this aim. The obtained results confirm the necessity of structuring the virtual community with a selection of active developers and core members to promote community activity and attract peripheral users, expanding the impact of the underlying software. The obtained result will be useful for the software industry migrating to the open source software paradigm
Web site structure mining using social network analysis
(2011) Martínez Torres, María del Rocío; Toral, S. L.; Palacios Florencio, Beatriz; Barrero, Federico; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Universidad de Sevilla. Departamento de Ingeniería Electrónica; Ministerio de Educación y Ciencia (MEC). España; Junta de Andalucía
Purpose – Web sites are typically designed attending to a variety of criteria. However, web site structure determines browsing behavior and way-finding results. The aim of this study is to identify the main profiles of web sites’ organizational structure by modeling them as graphs and considering several social network analysis features. Design/methodology/approach – A case study based on 80 institutional Spanish universities’ web sites has been used for this purpose. For each root domain, two different networks have been considered: the first is the domain network, and the second is the page network. In both cases, several indicators related to social network analysis have been evaluated to characterize the web site structure. Factor analysis provides the statistical methodology to adequately extract the main web site profiles in terms of their internal structure. Findings – This paper allows the categorization of web site design styles and provides general guidelines to assist designers to better identify areas for creating and improving institutional web sites. The findings of this study offer practical implications to web site designers for creating and maintaining an effective web presence, and for improving usability. Research limitations/implications – The research is limited to 80 institutional Spanish universities’ web sites. Other institutional university web sites from different countries can be analyzed, and the conclusions could be compared or enlarged. Originality/value – This paper highlights the importance of the internal web sites structure, and their implications on usability and way-finding results. As a difference to previous research, the paper is focused on the comparison of internal structure of institutional web sites, rather than analyzing the web as a whole or the interrelations among web sites
