title: Integración de los algoritmos de minería de datos 1R, PRISM e ID3 a PostgreSQL

description: In this research, data mining and decision tree techniques were analyzed as well as the induction of rules to integrate their many algorithms into the database managing system (DBMS), PostgreSQL, due to the defficiencies of the free use tools avaialable. A mechanism to optimize the performance of the implemented algorithms was proposed with the purpose of taking advantage of the PostgreSQL. By means of an experiment, it was proven that the time response and results obtained are improved when the algorithms are integrated into the managing system.

title: The role of worker tenure and employment heterogeneity on software development work activities

description: Software development group effectiveness depends on many factors, and understanding those factors is vital to project success, especially when considering the time and money that is dedicated to said projects. Therefore, this study examines the role of worker tenure and employment heterogeneity on exploration and exploitation work completed within an organization’s software development group. Analysis of time tracking data within one financial services organization over a three years period demonstrates that worker tenure and employment heterogeneity do play an important role in shaping work activities. Worker tenure exhibited a negative relationship with exploration and exploitation activities, suggesting a critical mechanism through which an organization can elicit innovative and incremental development efforts. Further, the positive effect of employment heterogeneity on exploration and exploitation suggests that employment diversity can also provide a means to encourage innovative and incremental development activities. Findings highlight the notion that group composition plays a meaningful role in shaping the focus of software development work within an organization.

title: The influence of shared mental models between the CIO and the Top Management Team on the strategic alignment of Information Systems: a comparison between brazilian and US companies

description: The gap in the understanding between the chief information officer (CIO) and the management team (TMT) has been cited as a contributing factor to their often troubled relationship. The objective of this study is to examine the development of shared mental models (SMMs) between the CIO and TMT about the role of information systems in the organization. An SMM is conceptualized as a multidimensional construct spanning the dimensions of shared language and shared understanding. The study posits that knowledge exchange mechanisms and relational similarity between the CIO and TMT are key antecedents to the development of SMMs. SMMs between the CIO and TMT are expected to guide the strategic orientation of the organization and may influence strategic alignment and organizational outcomes. The model was tested via a field survey of CIO – TMT pairs using structural equation modeling. Results show that relational similarity and formal mechanisms of knowledge exchange (e.g., formal CIO membership in the TMT, CIO hierarchical level, and formal educational mechanisms by the CIO) are important to the development of SMMs. Contrary to expectations, informal social mechanisms of knowledge exchange and physical proximity were not significantly related to SMMs.

title: Understanding organizational memory from the Integrated Management Systems (ERP)

description: With this research, in the form of a theoretical essay addressing the theme of Organizational Memory and Integrated Management Systems (ERP), we tried to present some evidence of how this type of system can contribute to the consolidation of certain features of Organizational Memory. From a theoretical review of the concepts of Human Memory, extending to the Organizational Memory and Information Systems, with emphasis on Integrated Management Systems (ERP) we tried to draw a parallel between the functions and structures of Organizational Memory and features and characteristics of ERPs. The choice of the ERP system for this study was made due to the complexity and broad scope of this system. It was verified that the ERPs adequately support many functions of the Organizational Memory, highlighting the implementation of logical processes, practices and rules in business. It is hoped that the dialogue presented here can contribute to the advancement of the understanding of organizational memory, since the similarity of Human Memory is a fertile field and there is still much to be researched.

title: Cash management policies by evolutionary models: a comparison using the Miller-Orr model

description: This work aims to apply genetic algorithms (GA) and particle swarm optimization (PSO) to managing cash balance, comparing performance results between computational models and the Miller-Orr model. Thus, the paper proposes the application of computational evolutionary models to minimize the total cost of cash balance maintenance, obtaining the parameters for a cash management policy, using assumptions presented in the literature, considering the cost of maintenance and opportunity for cost of cash. For such, we developed computational experiments from cash flows simulated to implement the algorithms. For a control purpose, an algorithm has been developed that uses the Miller-Orr model defining the lower bound parameter, which is not obtained by the original model. The results indicate that evolutionary algorithms present better results than the Miller-Orr model, with prevalence for PSO algorithm in results.

title: Metamodel of the it governance framework COBIT

description: This paper addresses the generation and analysis of the COBIT 4.1 ontological metamodel of IT Governance framework. The ontological metamodels represent the logical structures and fundamental semantics of framework models and constitute adequate tools for the analysis, adaptation, comparison and integration of IT best practice frameworks. The MetaFrame methodology used for the construction of the COBIT metamodel is based on the discipline of conceptual metamodeling and on the extended Entity/Relationship methodology. It has an iterative process of construction of the metamodel’s components, using techniques of modeling and documentation of information systems. In the COBIT 4.1metamodel, the central entity type is the IT Process. The entity type of IT Domain represents the four domains that group one or more IT processes of the COBIT 4.1. In turn, these domains are divided into one or more Activities that are carried through by one or more Roles which are consulted, informed, accounted for or liable for each Activity. The COBIT 4.1 metamodel may suggest adaptation or implementation of a new process within the framework or even contribute to the integration of frameworks, when, after the processes of analysis and comparison, there are connection points between the components and the logical structures of its relationships.

title: Impacts of a relationship model on informational technology governance: an analysis of managerial perceptions in Brazil

description: The aim of this article is to analyze the impacts, based on the perceptions of managers, of the deployment of a model to govern the relationship between business areas and IT in a large Brazilian financial organization. To undertake the case study of this deployment, the research firstly performed documental analyses of the process and then sent electronic surveys to a sample of managers in order to evaluate their perceptions of the model’s impact in terms of the formalism of the organization’s internal processes, strategic alignment between business areas and IT and levels of governance in the organization. The results revealed that managers perceived improvements in the quality of technological solutions, levels of IT governance, the understanding of IT area needs and business area demands, but they also stated that the negotiating process was more complex and there was no increase in their level of satisfaction with IT. These results of the study may contribute to the development of instruments for the evaluation of the impacts of the deployment of relationship models on important organizational aspects.

title: It management model for financial report issuance and regulatory and legal compliance

description: The development of information systems for financial report issuance must be adherent to the demands of the law and regulations that regulate the financial market. In order to perform this task, organizations need to implement control in the Information Technology (IT) area to maintain their systems´ conformity to laws and regulations. In the development of this work, it was found, through a state-of-art study, that there are no proposals contemplating the solution of this problem in its totality. In order to achieve this goal, in this paper it is presented a model for Information Technology management constituted by COBIT, ITIL and BPM management good practices, together with SOA and XBRL Technologies. This model is composed by 03 layers that aim at structuring the organization IT and business processes, besides defining a process for implementing SOA and integrating its Web services with XBRL language. One can expect this work to contribute to companies to decrease the negative impact coming from the lack of conformity with laws and regulations, through the creation of a corporative and IT environment that is flexible and more adaptable to changes, which may occur in legal demands, as well as improving the quality and reliability of financial report issuance.

title: Discovering citizens reaction toward e-government: factors in e-government adoption

description: E-government has been considered as one approach for changing the face of government in the eyes of the citizenry. Therefore, citizens’ socialization in relation to their engagement with e-government should be explored. This study argues that citizens played a significant role in determining the success of an e-government project in the Middle Eastern country of Jordan. This paper aims to provide insight and evaluation into the factors that could influence e-government’s effective functioning in the Jordanian social community through its interaction with citizens. The study collected data from 356 Jordanian citizens via a survey, to ascertain their understanding of 10 factors that may influence their intention to use e-government services. To investigate the adoption of e-government services in depth, two departments in Jordan were selected: the Jordanian Government’s Income and Sales Tax Department (ISTD) and its Driver and Vehicle Licenses Department (DVDL). The factor analysis technique was used to identify the main factors related to e-government services’ adoption. The results indicated that trust in the internet, website design, religious beliefs, internet and computer skill confidence, word of mouth, resistance to change, perceived usefulness, relative advantage and complexity are the main factors that should be considered when addressing the topic of e-government services’ adoption in Jordan. This study is different from most existing studies on e-government adoption as it empirically investigated the impact of word of mouth (WOM), wasta (favoritism), and resistance to change on e-government adoption. This study highlights the importance of considering the social cohesion of the Jordanian community when exploring factors related to e-government adoption.

title: Convergence in information and communication technology (ICT) using patent analysis

description: Since the 1990s, information and communication technology (ICT) has been perceived as the critical technology for economic development, and the ICT industry itself has been growing exceptionally fast. Moreover, technology convergence in ICT has received particular attention. ICT innovations diffuse into existing products and thus come to form a new integral part of the goods. This is an exploratory research to examine technology convergence of the supply side as a firm level in the ICT sector using International Patent Classification (IPC) of 43,636 sample patents from 1995 to 2008. This study finds a degree of merger and relationships between different technology domains through the association rule mining of patent co-classification. This type of analysis helps companies to take strategies under the environment of technological trajectory change.
