Intelligent learning environment for better student’s academic performance
2021
In this paper, the authors aim to develop an intelligent learning environment model designed to improve students’ academic performance. Methodology: Referring to the litarature, the authors identified and analyzed a number of relevant issues that influence the specific components of an intelligent learning environment. These aspects were quantified using performance indicators defined on the basis of the specific objectives of each aspect chosen. Results: Following the analysis, the authors developed a model of intelligent learning space, and for its representation, we used conceptual modeling. Conclusions: Finally, the authors propose the prevalidation of the model using the dynamic modeli…
The Art of Bootstrapping
2020
Language workbenches are used to define languages using appropriate meta-languages. Meta-languages are also just languages and can, therefore, be defined using themselves. The process is called bootstrapping and is often difficult to achieve.
The Influence of Context-Based Complexity on Decision Processes
2011
In this chapter, we present an empirical study which investigates the influence of context-based complexity on decision processes.1 To determine context-based complexity accurately, we measure each subject’s preferences individually with two advanced techniques from marketing research: choice-based conjoint analysis (CBC, Haaijer and Wedel 2007) and pairwise-comparison-based preference measurement (PCPM, Scholz et al. 2010), rather than relying on less precise estimates of preferences. Furthermore, we use eye tracking to trace the process of information acquisition precisely. Our results show that low context-based complexity leads to less information acquisition and more alternative-wise s…
Selection Task and Computer-Based Feedback to Improve the Searching Process in Task-Oriented Reading Situations
2015
Adaptive feedback has showed to be effective to enhance strategic reading behaviors and performance in task-oriented reading situations, but it is difficult to be implemented in classroom environments. Computer-based systems allow overcoming these challenges. We conducted an experiment in which secondary-school students read two texts, answered comprehension questions and selected relevant text information while receiving automatic feedback about selection accuracy and performance. Two experimental conditions were designed to assess the effects of feedback and selection attempts. Then, students perform a transfer task without any of these elements. We found that one-attempt and two-attempt …
Financial Evaluation of SLA-based VM Scheduling Strategies for Cloud Federations
2017
In recent years, cloud federations have gained popularity. Small as well as big cloud service providers (CSPs) join federations to reduce their costs, and also cloud management software like OpenStack offers support for federations. In a federation, individual CSPs cooperate such that they can move load to partner clouds at high peaks and possibly offer a wider range of services to their customers. Research in this area addresses the organization of such federations and strategies that CSPs can apply to increase their profit.In this paper we present the latest extensions to the FederatedCloudSim framework that considerably improve the simulation and evaluation of cloud federations. These si…
Enterprise System Implementation in a Franchise Context: An Action Case Study
2015
Abstract This research paper reports on a study focusing on a franchise relationship that utilizes an enterprise system (ES) to optimize its supply chain. The ES is in its post-implementation phase; however, the franchisee has challenges with inventory management due to poor data quality, which causes problems with vendor analysis and revenue control. An action case study was carried out to identify and diagnose the source of the problem, and interventions were implemented and evaluated. The findings demonstrate that several of the challenges related to poor data quality in the supply chain were influenced by problems of a socio-technical character. These included a lack of understanding of…
Decentralization and heterogeneity in complex adaptative systems
2015
Purpose – Following a bacterial-based modeling approach, the authors want to model and analyze the impact of both decentralization and heterogeneity on group behavior and collective learning. The paper aims to discuss these issues. Design/methodology/approach – Inspired by bacterial conjugation, the authors have defined an artificial society in which agents’ strategies adapt to changes in resources location, allowing migration, and survival in a dynamic sugarscape-like scenario. To study the impact of these variables the authors have simulated a scenario in which resources are limited and localized. The authors also have defined three constraints in genetic information processing (inhibiti…
Aims vs. technology: Pedagogical view to the use of educational applications in safety critical contexts
2011
Interactive technology for education has formed into a relatively independent domain of research and development. Interactive technology is often seen as a context independent tool. However, we argue that education in different contexts may have so different and incommensurable aims that no single technology can be announced as good or bad per se in terms of learning. The development of educational application should not be based on the technology to be applied, but by careful analysis of learning aims. When formulated in an appropriate way, learning aims work as a relevant basis in all stages of the design process of an educational application. The formulation of aims is therefore critical…
A Novel Framework of an Expert System by integrating Capability Approach and BRB to Evaluate E-Government Services
2015
Capability approach is hard to operationalize and capabilities are sometimes difficult to reduce into the individual level. We describe our approach to solve these problems paired with an adequate ICT infrastructure and believe that the impact of concrete eGovernment services will become more visible and available. Citizens can inspect it, professionals can target their re-engineering on failure cases, learn from best cases, and researchers can compare different types of eGovernment. The solving of operationalisation will also strengthen the capability approach, by extending its scope from macro theory towards more easy application on the institutional and organizational levels.

The Design and Execution of Performance Management Systems at State Level: A Comparative Analysis of Italy and Malaysia
2016
ABSTRACTThis comparative study analyses the experience of Italy and Malaysia in the design and execution of performance management systems at the state level. The article investigates how performance management systems have changed over the past decades, the motivations behind their metamorphoses, their common elements across the two countries, and what accounts for the respective progress. It also investigates the role that the institutional framework plays in making performance management systems robust. The study presents policy recommendations on how governments can create more robust performance management systems for enhanced accountability and transparency in an age of resource const…
