Supporting End-User Development through a New Composition Model: An Empirical Study

End-user development (EUD) is much hyped, and its impact has outstripped even the most optimistic forecasts. Even so, the vision of end users programming their own solutions has not yet materialized. This will continue to be so unless we in both industry and the research community set ourselves the ambitious challenge of devising end to end an end-user application development model for developing a new age of EUD tools. We have embarked on this venture, and this paper presents the main insights and outcomes of our research and development efforts as part of a number of successful EU research projects. Our proposal not only aims to reshape software engineering to meet the needs of EUD but also to refashion its components as solution building blocks instead of programs and software developments. This way, end users will really be empowered to build solutions based on artefacts akin to their expertise and understanding of ideal solution

Una aproximación al estudio de la marca ciudad. Aplicación a la ciudad de Almería

El marketing de ciudades conforma un interesante instrumento estratégico para facilitar a las ciudades la satisfacción de las exigencias de sus diferentes públicos objetivo, a través del diseño y ejecución de procesos de creación y transmisión de valor, con el fin de mejorar su posicionamiento competitivo en relación con las ciudades competidoras. Así, la capacidad de desarrollo de una marca-ciudad, mediante la vinculación de la misma con su principal esencia en materia de historia, cultura y beneficios que la definen, puede mejorar la competitividad de una ciudad, potenciando aquellos elementos que la hacen única ó diferente a las demás. En particular, la provincia de Almería adolece de notables deficiencias en infraestructuras y comunicaciones, que unidas al posicionamiento de algunas de sus ciudades competidoras, plantean la necesidad de reflexionar en este trabajo en curso sobre el posicionamiento de su oferta y el grado de satisfacción que los diferentes públicos objetivo poseen con la ciudad.City marketing represents an interesting strategic tool in order to facilitate cities the satisfaction of the demands of their different target groups, through the design and execution of processes of creation and transmission of value, looking for the improve of their competitive positioning. Thus, the ability to develop a city-branding, by linking with its main essence in terms of history, culture and benefits that define it, can improve the competitiveness of a city, enhancing those elements that make it unique or different from other competitive cities. In particular, the province of Almeria suffers from notable deficiencies in infrastructure and communications, coupled with the positioning of some of its competing cities, suggest the need to reflect on this ongoing work the positioning of its offer and the degree of satisfaction that the different target publics possess with the city

Respuestas de los consumidores a los hoteles certificados medioambientalmente: el efecto moderador de la conciencia medioambiental sobre la formación de intenciones comportamentales

Este estudio desarrolla un modelo que explora la relación entre las prácticas verdes, la imagen verde, la conciencia medioambiental y las intenciones comportamentales de los clientes en un contexto hotelero certificado. Para testar empíricamente el modelo propuesto se realizaron 502 encuestas personales a clientes hoteleros en España. Los resultados muestran como las percepciones de los clientes sobre las prácticas verdes tienen un efecto directo y positivo en la imagen verde de las compañías hoteleras. Al mismo tiempo, esta imagen influye directa y positivamente sobre las intenciones de comportamiento de los clientes hacia los hoteles certificados medioambientalmente. También se demuestra que cuanto mayor sea la conciencia medioambiental de los consumidores, mayor será su intención de hospedarse, realizar comentarios positivos y pagar una prima por alojarse en hoteles certificados. Por último, la conciencia medioambiental ejerce un efecto moderador sobre la relación causal entre la imagen verde y las intenciones comportamentales.This study develops a model that investigates the relationship among green practices, green image, environmental consciousness and the behavioral intentions of customers in a certified hotel context. The study examines the direct and the moderating role of environmental consciousness in the formation of behavioral intentions based on green initiatives. To test the proposed model empirically, 502 personal surveys of hotel customers were conducted in Spain. The findings show that customer perceptions of green practices have a positive direct effect on a hotel´s green image. At the same time, this environmental image has positive direct effects on customer behavioral intentions towards certified hotels. The authors also found that the higher the environmental consciousness of consumers, the greater their intention to stay, to spread positive word-of-mouth and pay a premium for environmentally-certified hotels. Finally, consumer environmental consciousness also exerts a moderating effect on the causal relationship between green image and behavioral intentions

Bernstein polynomials in element-free Galerkin method

In the recent decades, meshless methods (MMs), like the element-free Galerkin method (EFGM), have been widely studied and interesting results have been reached when solving partial differential equations. However, such solutions show a problem around boundary conditions, where the accuracy is not adequately achieved. This is caused by the use of moving least squares or residual kernel particle method methods to obtain the shape functions needed in MM, since such methods are good enough in the inner of the integration domains, but not so accurate in boundaries. This way, Bernstein curves, which are a partition of unity themselves,can solve this problem with the same accuracy in the inner area of the domain and at their boundaries

Sinorhizobium fredii Strains HH103 and NGR234 Form Nitrogen Fixing Nodules With Diverse Wild Soybeans (Glycine soja) From Central China but Are Ineffective on Northern China Accessions

Sinorhizobium fredii indigenous populations are prevalent in provinces of Central China whereas Bradyrhizobium species (Bradyrhizobium japonicum, B. diazoefficiens, B. elkanii, and others) are more abundant in northern and southern provinces. The symbiotic properties of different soybean rhizobia have been investigated with 40 different wild soybean (Glycine soja) accessions from China, Japan, Russia, and South Korea. Bradyrhizobial strains nodulated all the wild soybeans tested, albeit efficiency of nitrogen fixation varied considerably among accessions. The symbiotic capacity of S. fredii HH103 with wild soybeans from Central China was clearly better than with the accessions found elsewhere. S. fredii NGR234, the rhizobial strain showing the broadest host range ever described, also formed nitrogen-fixing nodules with different G. soja accessions from Central China. To our knowledge, this is the first report describing an effective symbiosis between S. fredii NGR234 and G. soja. Mobilization of the S. fredii HH103 symbiotic plasmid to a NGR234 pSym-cured derivative (strain NGR234C) yielded transconjugants that formed ineffective nodules with G. max cv. Williams 82 and G. soja accession CH4. By contrast, transfer of the symbiotic plasmid pNGR234a to a pSym-cured derivative of S. fredii USDA193 generated transconjugants that effectively nodulated G. soja accession CH4 but failed to nodulate with G. max cv. Williams 82. These results indicate that intra-specific transference of the S. fredii symbiotic plasmids generates new strains with unpredictable symbiotic properties, probably due to the occurrence of new combinations of symbiotic signals.España, Junta de Andalucía P11-CVI-7500España Ministerio de Economía y Competitividad BIO2016-78409-

A component- and connector-based approach for end-user composite web applications development

Enabling real end-user development is the next logical stage in the evolution of Internet-wide service-based applications. Successful composite applications rely on heavyweight service orchestration technologies that raise the bar far above end-user skills. This weakness can be attributed to the fact that the composition model does not satisfy end-user needs rather than to the actual infrastructure technologies. In our opinion, the best way to overcome this weakness is to offer end-to-end composition from the user interface to service invocation, plus an understandable abstraction of building blocks and a visual composition technique empowering end users to develop their own applications. In this paper, we present a visual framework for end users, called FAST, which fulfils this objective. FAST implements a novel composition model designed to empower non-programmer end users to create and share their own self-service composite applications in a fully visual fashion. We projected the development environment implementing this model as part of the European FP7 FAST Project, which was used to validate the rationale behind our approach

Automated end user-centred adaptation of web components through automated description logic-based reasoning

Context: This paper addresses one of the major end-user development (EUD) challenges, namely, how to pack today?s EUD support tools with composable elements. This would give end users better access to more components which they can use to build a solution tailored to their own needs. The success of later end-user software engineering (EUSE) activities largely depends on how many components each tool has and how adaptable components are to multiple problem domains. Objective: A system for automatically adapting heterogeneous components to a common development environment would offer a sizeable saving of time and resources within the EUD support tool construction process. This paper presents an automated adaptation system for transforming EUD components to a standard format. Method: This system is based on the use of description logic. Based on a generic UML2 data model, this description logic is able to check whether an end-user component can be transformed to this modeling language through subsumption or as an instance of the UML2 model. Besides it automatically finds a consistent, non-ambiguous and finite set of XSLT mappings to automatically prepare data in order to leverage the component as part of a tool that conforms to the target UML2 component model. Results: The proposed system has been successfully applied to components from four prominent EUD tools. These components were automatically converted to a standard format. In order to validate the proposed system, rich internet applications (RIA) used as an operational support system for operators at a large services company were developed using automatically adapted standard format components. These RIAs would be impossible to develop using each EUD tool separately. Conclusion: The positive results of applying our system for automatically adapting components from current tool catalogues are indicative of the system?s effectiveness. Use of this system could foster the growth of web EUD component catalogues, leveraging a vast ecosystem of user-centred SaaS to further current EUSE trends
