Development of a change framework to study SME web site evolution

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.It has been suggested that the adoption of e-commerce by Small and Medium-sized Enterprises (SMEs) follows a sequence of stages with each representing increasing complexity and benefits. These models imply a development of their web sites in successive iterations or redesigns from basic use of the Internet (as a marketing tool) to the most advanced level of sophistication and integration. The EU and the UK government appear to believe such models and have used them in their e-commerce adoption encouragement policies for SMEs. However, recent research in Europe reveals that e-commerce initiatives in SMEs in most cases are still in their initial stages, which do not exceed the use of email and simple information-based web pages. This failure of SMEs to engage in the more advanced stages of adoption suggest that our understanding of the implementation and management of SME web sites over time is too limited. Thus, the main aim of this research is to establish an enhanced understanding of the dynamics of SME web site transformations over time to better support SME e-commerce progression. The specific objectives of this research are to (1) examine the literature that explain or guide the evolution of web sites and internet strategies, particularly in the context of SMEs, (2) develop a multidimensional framework that combines three dimensions of organisational change (extent, content and drivers) to characterise and model the evolution of the web presence of SMEs and (3) undertake a study of the types and characteristics of actual changes on a sample of SME web sites over time to demonstrate the relevance and applicability of the dimensions of the framework. This study employs both quantitative and qualitative techniques. The quantitative part of the study includes the collection and observation of the sample of SME web sites to study the extent of the changes and the content of the changes incorporated. The qualitative part of the study involves telephone interviews to seek additional information about the drivers for web site redesigns and complement the previous observations. It is argued that a research framework that combines three different dimensions of organisational change offers an alternative approach to e-commerce Stage Models in understanding the evolution of SME web sites over time. The developed framework is useful to academics by providing multiple perspectives that enable more insightful study of SME web site evolution, and avoid over-simple, a priori theory, e. g. staged approach. The framework is also argued to be useful for SME managers seeking to make the most of their limited resources in this context

Theoretical Approaches to Study SMEs eBusiness Progression

It has been suggested that the adoption of Internet technologies by SMEs follows an ordered sequence of stages and staged models to describe it. These models postulate that businesses move in stages from basic use of the Internet to the full integration of business systems and redesign of business processes. The European Union and the UK government appear to believe in such models and have used them in their e-business adoption encouragement policies for SMEs. However, despite the efforts of governments and the various support programs, the attainment of the advanced stages of e-commerce by SMEs is very low. Indeed, several studies into the state of e-business in the UK report a decline in the number of SMEs implementing e-trading and even using website and e-mail. Hence, perhaps these adoption models need to be questioned and even revised. There are a number of authors that have already critized these models suggesting that they are too general and do not take into account the diversity of SMEs. Therefore, the aim of this paper is to conduct an analysis of the Stages of Growth model looking at its weaknesses and strengths in the context of the progression of Internet technologies adoption by SMEs in the UK. In addition, alternative explanations of e-business progression will be presented and an interpretative multi-theoretical framework to study this evolution will be suggested

Infective endocarditis due to Bartonella bacilliformis associated with systemic vasculitis: a case report

Infective endocarditis due to Bartonella bacilliformis is rare. A 64-year-old woman, without previous heart disease, presented with 6 weeks of fever, myalgias, and arthralgias. A systolic murmur was heard on the tricuspid area upon examination, and an echocardiogram showed endocardial lesions in the right atrium. Bartonella bacilliformis was isolated in blood cultures, defining the diagnosis of infective endocarditis using Duke’s criteria. Subsequently, the patient developed clinical and laboratory features compatible with antineutrophil cytoplasmic antibody-associated vasculitis. This case presents an uncommon complication of B. bacilliformis infection associated with the development of systemic vasculitis.Revisión por pare

Social support, network, and relationships among coaches in different sports: a systematic review

Introduction: The study aims to analyze scientific publications on the association between social networks, social relationships, and social support for sports coaches. It seeks to identify the types and levels of social support provided by various agents, and to understand the impact of this support on coaches’ wellbeing. The goal is to help coaches better utilize social support, thereby enhancing their quality of life, work, and performance. Methods: This study systematically reviewed 11 scientific articles to investigate the association between social support, social networks, and social relationships in sports coaches. It aimed to identify the types and levels of social support offered to coaches by family members, peers, and friends. Our research utilized the PRISMA guidelines for systematic reviews and assessed study quality using the STROBE Statement. Eligibility was determined by the PECOS criterion based on the search strategy terms. Results: Our findings indicate that social support has significant positive effects on sports coaches. It enhances selfcompassion, prevents burnout symptoms, boosts job and life satisfaction, and reduces stress levels. Organizational support, characterized by clear guidelines, guidance, and autonomy, yielded positive outcomes. Conversely, the absence of social support correlated with negative outcomes for coaches, including lower self-compassion, increased stress and burnout symptoms, reduced job and life satisfaction, and heightened work–family conflict. Coaches’ social networks encompassed family members, peers, friends, and other sources, with friends perceived as the most influential. Maintaining an effective social support network is crucial for coaches’ performance and psychological wellbeing. Discussion: This systematic review emphasizes the importance of social support for coaches in both their personal and professional lives, noting its positive effects and the negative consequences of its absence. Given the demanding nature of coaching, improving social support systems can enhance coaches’ wellbeing and the success of sports activities.info:eu-repo/semantics/publishedVersio

La producción informativa y documental del Estado: hacia un inventario de los recursos públicos

The internet offers a new way of shaping the messages that the State transmits to its citizens and provides a means of generating new relationships with them. With this in mind, this paper focuses on how State-produced information should be organized to provide a useful information service. The proper generation and management of public sector information is essential, not just for its own inherent value but because of the economic assets with which it deals. In this context of the access to and the re-use of public information there is also a need for the use of specific terminology. This paper sets out the general principles governing the management of information generated by the public sector and, with respect to the inventory principle, summarizes the main results obtained within the framework of our research group on the identification and description of public sector information and documentation assets, particularly those of State authorities. This subject is of great interest to practitioners and researchers in Library and Information Science, since it puts into perspective the value of documentary information resources and provides great impetus for the creation of a public information services market.Internet supone un nuevo escenario en la configuración de los mensajes que el Estado dirige a sus ciudadanos, así como en la generación de nuevas relaciones con los mismos. Desde ese enfoque, nos centraremos en cómo la producción de información del Estado debe ser organizada para que los ciudadanos reciban un conjunto de servicios informativos. Una adecuada creación y manejo de la información del sector público es crucial tanto por su valor en sí misma como por los activos económicos que representa. Además, en este contexto del acceso y la reutilización de la información pública se plantea la necesidad de contar con una terminología específica. Se establecen los principios de aplicación general que ha de regir el tratamiento de la información generada por el sector público y, en relación con el principio de inventario, se resumen los principales resultados obtenidos en el marco del Grupo de investigación sobre la identificación y descripción de los activos de información y documentación del sector público, en particular de la Administración General del Estado. El tema es de gran interés para los profesionales e investigadores en Biblioteconomía y Documentación, ya que esta perspectiva pone en valor los recursos de información documental y propicia un gran impulso a la creación de un mercado de servicios de información pública
