The recent advances in information and communication technologies (ICT) have resulted in unprecedented growth in available data and information. Consequently, intelligent knowledge creation methods are needed. Organizations need efficient intelligent text mining methods for classification, categorization and summarization of information available at their disposal. Neural Networks have successfully been used in a wide variety of classification problems. The purpose of this dissertation is two-fo...

The focus of this paper is to provide practical guidelines for designing service scheduling support systems based on the Object-Orientation Approach (OOA). The advantages of OOA include providing greater flexibility to the process of system design and implementation, simplifying the decision making process and empowering decision-makers at the operational level. The application domain of this paper is healthcare where patient scheduling has always been a major challenge due to the high degree of...

Abstract Because of its unique characteristics, Albania is faced with severe challenges. Business education is no exception. The baggage of its tragic past, under a ruthless communist dictatorship, especially the isolation of its people from free thought for almost 50 years, still lingers in people's thinking and behaviors. Generally, the Albanian schools system is well developed and there is a tradition of sound education. However, Albanian institutions of higher education are ill prepared to p...

AbstractGoal programming has proven a valuable mathematical programming form in a number of venues. There has been a similar rapid growth in interest in data mining, where a variety of different data types are encountered. This paper applies goal programming formulations to compare relative performance of L1, L2, and L∞ norms as well as ordinal and ratio data types in a dynamic predictive environment. The models are applied to compare relative accuracy and stability in forecasting a professional...

ABSTRACT Although e-commerce is evolving at an incredible speed, asymmetric information and opportunism have increased online purchasing risks and market inefficiencies. The lack of face-to-face contact and the inability of the customer to touch and feel tangible products necessitate that online business must provide customers with reliable information and convince customers of their trustworthiness. While the research on Third-Party Assurance Seals (TPAS) is not new, the effectiveness of TPAS h...

In spite of continuous organizational efforts and investments, computer abuse shows no sign of decline. According to social control theory (SCT), "organizational trust" can help prevent it by enhancing insiders' involvement in computer abuse. The aim of our study was to develop a new integrative model for analyzing computer abuse through assessing the role of Self Defense Intention (SDI) and Induction Control Intention (ICI). The results show that deterrence factors influence SDI and organizatio...

Flexibility, speed, and efficiency are major challenges for operations managers in today's knowledge-intensive organizations. Such requirements are converted into three production scheduling criteria: (a) minimize the impact of setup times in flexible production lines when moving from one product to another, (b) minimize number of tardy jobs, and (c) minimize overall production time, or makespan, for a given set of products or services. There is a wide range of solution methodologies for such NP...

This study investigates the relationship between the implementation of data warehousing and organizational performance in retailing firms. For this research goal, five hypotheses are developed and tested. The paired T-tests and Hotelling's T-square tests are performed on two groups — retailing firms implementing data warehousing and those that do not. The results of analyses show that data warehousing firms achieve better nonfinancial performance, including promotional performance analysis, vend...

Research on decision support systems (DSS)/executive information systems (EIS) has been primarily concerned with the behavioral aspect of managerial work and has largely ignored the cognitive aspect of decision support. Rather than focusing on the manager's information need on "critical success factors" and the need for supporting specific decision making, this research emphasizes the need to support the decision maker's general thinking processes to reduce cognitive biases in decision making. T...
