No full textBrazilian scientific journals that use the Open Journal Systems (OJS): a quality analysis
No full textThis study aims to assess the quality of Brazilian journals that use the Open Journal Systems (OJS) in order to be published. For this purpose, the main criteria used to assess quality were sought in the available literature, and a selection was made of those considered to be of great relevance. The universe of the research was comprised of journals that were correctly registered under their respective subject heading in the system website by June 2010, a total of 236. The sample\u27s nature is intentional and, according to the established criteria, 78 journals were selected for the study. The quality aspects evaluated were: editorial board, authors, rules for article submission, peer review, age, format, language of publication and the journal impact. The criteria were assessed by indicating the presence/absence of the quality indicator or by attributing a poor/reasonable/good, quality scale, according to the criterion assessed. The results indicate that the criteria established for authors, rules for article submission, and format were positively evaluated. The editorial board was also positively assessed, although 38% of the journals analysed did not present the composition of this group on their websites. The peer review criterion was negatively assessed, since only 17% of the journals correctly inform how the article evaluation process occurs and what criteria are used in the assessment of the submitted articles. Furthermore, it was identified the existence of a moderate positive relation between the H-index of the journals and their ages, and that there is no correlation between the language of article publication and the H-index of the journals
Towards active seo (search engine optimization) 2.0
No full textIn the age of writable web, new skills and new practices are appearing. In an environment that allows everyone to communicate information globally, internet referencing (or SEO) is a strategic discipline that aims to generate visibility, internet traffic and a maximum exploitation of sites publications. Often misperceived as a fraud, SEO has evolved to be a facilitating tool for anyone who wishes to reference their website with search engines. In this article we show that it is possible to achieve the first rank in search results of keywords that are very competitive. We show methods that are quick, sustainable and legal; while applying the principles of active SEO 2.0. This article also clarifies some working functions of search engines, some advanced referencing techniques (that are completely ethical and legal) and we lay the foundations for an in depth reflection on the qualities and advantages of these techniques
It outsourcing: methodology for selecting suppliers criterion for competitive advantage
No full textThe main reasons that motivate companies to outsource the services of Information Technology (IT) are: reducing costs, improving service quality and concentration on their core competencies. And the decision criteria of the contracting company are focused on those reasons. This article proposes a strategic criterion: the company should hire the supplier that best leverages their competitive advantages. This criterion implies the need to develop a specific methodology to this purpose, which is reported in this paper. To support it, the authors analyzed the models of Porter, Resource-Based View, Balanced Scorecard and the Fields and Weapons of the Competition, and making an option for the latter. The methodology was developed and applied to an Insurance Company and accepted by their leaders
Software process assessment and improvement using Multicriteria Decision Aiding - Constructivist
No full textSoftware process improvement and software process assessment have received special attention since the 1980s. Some models have been created, but these models rest on a normative approach, where the decision-maker\u27s participation in a software organization is limited to understanding which process is more relevant to each organization. The proposal of this work is to present the MCDA-C as a constructivist methodology for software process improvement and assessment. The methodology makes it possible to visualize the criteria that must be taken into account according to the decision-makers\u27 values in the process improvement actions, making it possible to rank actions in the light of specific organizational needs. This process helped the manager of the company studied to focus on and prioritize process improvement actions. This paper offers an empirical understanding of the application of performance evaluation to software process improvement and identifies complementary tools to the normative models presented today
Antecedents of end-user satisfaction with an erp system in a transnational bank: evaluation of user satisfaction with information systems
Get PDFThe main objective of this study is to identify the antecedents of end-user satisfaction with an Enterprise Resource Planning (ERP) system, in the context of a transnational Bank. The Information System (IS) success theory is applied for the end-user computing satisfaction (EUCS) assessment. Quantitative data is analyzed through multivariate statistical techniques whereas qualitative data is analyzed through content analysis technique. The results indicate that the EUCS model is pertinent to the context of ERP systems for a fast data collection and overall perception of user satisfaction; nevertheless it is suggested the continuity of its evaluation in other research contexts and additional categories should be considered as antecedents to IS enduser satisfaction
CRM as a support for knowledge management and customer

Decision strategies in dynamic systems using fuzzy cognitive maps: Application to a socio - economic example
Get PDFLas situaciones que abarcan el contexto en que el ser humano desarrolla sus tareas cotidianas son extremadamente complejas y dinámicas. En cada campo, el análisis de las variables que componen el sistema objeto de estudio puede simplificarse si se lo concibe compuesto como un conjunto de conceptos donde un cambio en cada uno de ellos provocará cambios en los restantes. Cuando se trata de analizar la problemática de un área particular, la representación de los conceptos en forma de un mapa permite sintetizar la información aislando los principales conceptos que están vinculados en el problema. En estos casos los Mapas Cognitivos Difusos (MCD) logran sintetizar gran parte de la información presente. Además con esta técnica es posible seguir la evolución de los conceptos hasta un estado de equilibrio y por lo tanto permiten estudiar la dinámica que lleva el pasaje de un estado a otro determinado en la situación que se analiza. En este trabajo se expone la técnica de construcción y análisis de Mapas Cognitivos Difusos a través de un ejemplo de aplicación a la economía. El objetivo consiste en presentar una metodología de trabajo apoyada en los MCD que permite analizar la evolución y el impacto que provoca en el sistema el cambio en el valor de uno o varios conceptos intervinientes.Situations in which human beings develop their daily tasks are extremely complex and dynamic. In each field, the analysis of the system\u27s variables under consideration can be simplified if the system is conceived as a set of concepts, where a change in each of them will cause changes in the remainder. In the analysis of a particular problem, the representation of concepts in the form of a map helps to synthesize information detecting the main concepts that are linked to the problem. In these cases, Fuzzy Cognitive Maps (FCM) are able to synthesize much of this information. Also with this technique is possible to follow the evolution of the concepts to a state of equilibrium and therefore allow us to study the dynamics that takes the passage from one state to another given the situation under review. This paper describes the construction and analysis of the Fuzzy Cognitive Maps technique through an economy application example. The aim is to present a methodology supported by the FCM to analyze the evolution and impact on the system causing by the change in the value of one or more concepts involved
