Researchers, in Multimodal Interaction Systems, devote substantial effort to the integration of external stimulus and signal, to the internal representation of this information and to the response generation. Nevertheless, they focus less effort on how to integrate studies in Cognitive Psychology regarding the human interaction subject. Therefore, it becomes interesting to evaluate the assumption that a dialog model based on known human factors should outcome better perception of the interaction process by the users. This paper presents an experimental approach to implement multimodal interaction systems where the main innovative aspect is related to the dialogue managing, that is based on the working memory model proposed by Baddeley and Hitch. A computational model was proposed and two different prototypes were built. The obtained results were found to be positive and it indicates relevant flexibility aspects together with anencouraging feedback from users.

The main focus of this article is the economic value creation within social media enterprises. This article will examine different models within this domain. The work has not only identified the main strengths and weaknesses of each model, but also highlighted the differences and similarities between them.

In today’s business the optimization of the alignment between Business and IT can be assessed as a critical success factor for enterprises. Enterprise Architecture (EA) is used by enterprises for providing an integrated environment in order to support this Business-IT-Alignment. But establishing EA practice still remains a challenging endeavor with low success rates. Mayor reasons for that are the high complexity of the enterprise models and the resultant necessity for stakeholder specific visualization of the enterprise model, the different information requirements of different stakeholder groups, and the not sufficient integration of EA in the management processes and IT management tools used by a company. For this reason we argue that the business management of an enterprise and the Enterprise Architecture Management (EAM) of the company should be integrated in a more consistent way to minimize application proliferation and to avoid information system silos. One possibility for achieving this is to provide and to visualize all necessary management information in only one IT-tool which is well integrated in the management processes of a company. In the business management context Business Intelligence (BI) systems are information integrators which allow stakeholder specific visualization and analyses of high quality and integrated business data. Also EAM systems have to collect, to manage and to visualize information from one or various sources. In this paper we demonstrate how information needed by EAM can also be modelled, stored, and business friendly visualized within a BI system. Thus, we demonstrate how Enterprise Architecture Visualization can be managed by a BI system.

E-government refers to the delivery of government information and services online through the Internet or other digital means (West, 2004), and well-implemented e-government platforms can help to improve the business environment and the creation of new businesses. The present article has as its main goal to measure the impact of change of the index of e-readiness of e-Government (and its sub-indices) on ease of doing business, in the new business rate and the perception of corruption in countries of high, medium and low income, in order to test whether the effects depend on the income level. The study used a panel data (repeated measures), with four points (years 2008, 2010, 2012 and 2014), with three periods of change (2008/2010, 2010/2012 and 2012/2014), with data the following databases: Doing Business Report of the World Bank, the United Nations Survey on e-Government, Corruption Perception Index of Transparency International and World Bank’s Survey on Entrepreneurship. Data were analyzed using Mixed Linear Models procedures with fixed and random effects. The findings indicate that different models should be employed to understand e-government impact depending on the income level of the countries, since they have a very diverse technological and service delivery capacity and different population profiles when compared on digital and Internet use, and even cultural traits. Thus, the findings support the hypothesis that the effects are diverse and depend on the income level. Indications for future research are discussed.
