Computers are perceived as an important tool in the world of education. Computer technology today when used in teaching and learning could open the world to students. However when learning is concern, emotions relevant to learning should not be forgotten. Thus emotional intelligence should be considered when computers and learning is concern. There is very little research on the effect of emotional intelligence on learning and on technology. As learning with technology relates to computers, thus this study focuses on the relationship between emotional intelligence and attitudes towards computer. Based on this study it was found that emotional intelligence of the polytechnic engineering students was average and their attitudes towards computers were positive. The relationship between emotional intelligence and attitude towards computer is positive but very weak. Significant difference were found when gender was compared however CGPA (Cumulative Grade Point Average) and ownership of computers did not affect this relationship.

The Relationship between Slack Resources and Performance: An Empirical Study from China
Статья научная
Although organizational research posits various relationships between a firm’s slack resources and performance, findings to date have been ambiguous. The purpose of this study is to attempt to reconcile previous views of the relationship between slack resources and performance through employing empirical analysis based on survey data from 47 pharmaceutical and chemical firms in Henan Province of China. The results indicate that the relationship between slack resources and the performance is inverse N-shaped. Results provide evidence of a curvilinear relationship between slack resources and performance and broadly demonstrate that relationships differ based on industry circumstances and slack resources. Additionally, this study is the first to empirically identify an inverse N-shaped relationship between slack resources and performance, indicating that, in certain industry circumstances, little and much slack resources are bad for performance. Overall, results highlight the importance of additional research into intervening factors impacting the slack–performance relationship.

The Solution of Scalar Bimatrix Games in Preferred Pure Strategies
Статья научная
In the present work the task of finding Nash equi-librium situation or finding the most preffered pure strategies in finite scalar m x n bimatrix Γ(A, B) game is studied. The problem of finding an equilibrium in the Γ(A, B) game has a long history, but due to the complexity of the known algorithms and methods, that cause various problems, its study is being continued today. Our approach is different from these methods. In order to find an equilibrium situation in the pure strategies, we mean making a prediction by each player about the second player's behavior for choosing preferred pure strategy. Therefore we use a sequential strictly and weakly procedure of dominance for comparing of two pure strategies. Only in the case of strictly dominance the line of dominance has no meaning in order to maintain an equilibrium situation in pure strategies. We don’t have such kind of situation in every game. In this kind of game each player can act by different principles to define the most preferred pure strategy, that is based on making a prediction about his partner’s behavior by the player and that means the orientation on guaranteed levels in concrete situations. We mean the orientation in A and B matrix games average V(A) and V( BT) playoffs obtained by the players using maximum optimal mixed strategies. Each player’s decisions are discussed about the usage the preferred pure strategies related to his partner’s actions. By using them he will gain much more, then in an equilibrium situation. All kinds of other actions are also discussed. Acceptable results are used for solution of high ranged m x n (m>2, n>2) Bimatrix Γ(A, B) games.

The Stability of Equilibrium Situation in Lexicographic Strategic Games
Статья научная
The present work deals with lexicographic noncooperative (strategic) games in which the set of strategies of the players are metric compact spaces and the vector-functions of winning are continuous on the set of situations. In such games we introduce the definition of a weak nonstrict (determined by usual nonstrict lexicographic inequality) of Nash equilibrium situation in pure strategies. It has been defined the stability of such equilibrium situation and of lexicographic noncooperative game in relation to change of vector-functions of the winning of players, a problem of an equilibrium stable situation and availability of lexicographic noncooperative game has been studied. The conditions of their stability have been brought. The identification of the indicated conditions has been connected with those features of the task of lexicographic maximum that differs from the task of scalar maximum: the set of points of lexicographic maximum in the task of lexicographic maximum of continuous vector-function defined on metric compact is compact. And in the lexicographic noncooperative game the set of equilibrium situations may not be compact. In particular, it is certified that if in lexicographic game there is only one equilibrium situation then it is a stable situation and the relative game is stable.

The Stability of Memory Rules Associative with the Mathematical Thinking Core
Статья научная
Activation of how and where arithmetic operations are displayed in the brain has been observed in various number-processing tasks. However, it remains poorly understood whether stabilized memory of Boolean rules are associated with background knowledge. The present study reviewed behavioral and imaging evidence demonstrating that Boolean problem-solving abilities depend on the core systems of number-processing. The core systems account for a mathematical cultural background, and serve as the foundation for sophisticated mathematical knowledge. The Ebbinghaus paradigm was used to investigate learning-induced changes by functional magnetic resonance imaging (fMRI) in a retrieval task of Boolean rules. Functional imaging data revealed a common activation pattern in the left inferior parietal lobule and left inferior frontal gyrus during all Boolean tasks, which has been used for number-processing processing in former studies. All other regional activations were tasks-specific and prominently distributed in the left thalamus, bilateral parahippocampal gyrus, bilateral occipital lobe, and other subcortices during contrasting stabilized memory retrieval of Boolean tasks and number-processing tasks. The present results largely verified previous studies suggesting that activation patterns due to number-processing appear to reflect a basic anatomical substrate of stability of Boolean rules memory, which are derived from a network originally related to the core systems of number-processing.

Статья научная
The Balanced Scorecard has been adopted as a management and measurement system around the world. It is adopted as a measure to assess the efficiency of an organization's activities. The Balanced Scorecard measures four dimensions of organizational activities – internal processes, financial, external customers and learning and growth perspective. These focus on critical issues impacting modern business organizations that are the effective measurement of corporate performance and evaluation of the success of implementation of corporate strategy. This study explores the Balanced Scorecard as applied in higher education through a case study of the, School of Information and Communication Technology, Phayao University. This study seeks to explore the application of the Balanced Scorecard as a measurement system and its effectiveness in organizational evaluation within the School. In identifying a strategy to implement the Balanced Scorecard within the School each dimension is considered such as internal processes, financial, internal customer and learning and growth. This research began by examining practices in place and linking them to a Balanced Scorecard approach. The intention is being to identify administrative and tracking systems for performance measurement within the School. A model is then identified to collect data across the dimensions of the balanced scorecard, and performance criteria identified. In implementing this phase scores will be associated with performance within the four dimensions. This will enable an evaluation of the model, contribute to software improvement and assist users in conducting accurate and effective strategic planning. It is then hoped to implement the model within the School in strategy plans and operation of the School to improve the assessment of the performance, and identify areas of improvement and change that is desirable.

The Study of Blended Learning on a Vocational High School in Taiwan
Статья научная
With the contributions of computer technology, digital learning has evolved into a stage of mobile learning. However, school classes require teachers to perform face-to-face humanized lectures. Digital learning remains to function as a tool for assisted teaching. Few studies have investigated what proportions digital learning should occupy in teaching activities. In this study, to investigate the optimal proportion of face-to-face instructions and digital learning, we conducted a one-semester teaching experiment on two classes of students in the informatics department in a public vocational high school in Taipei City. In addition, the Kruskal-Wallis one-way analysis of variance was adopted for the statistical analysis to determine the optimal blending proportions. Our results indicate that optimal effects are achieved at a time ratio of 2:1 of traditional face-to-face teaching to digital learning.

The circumstances in which modular programming becomes the favor choice by novice programmers
Статья научная
One of the key indicators for testing code quality is the level of modularity. Nevertheless, novice programmers do not always stick to writing modular code. In this study, we aim to examine the circumstances in which novice programmers decide to do so. To address this aim, two student groups, twenty each, were given a programming assignment, each in a different set-up. The first group was given the assignment in several stages, each add complexity to the previous one, while the second group was given the entire assignment at once. The students' solutions were analyzed using the dual-process theory, cognitive dissonance theory and content analysis methods to examine the extent of modularity. The analysis revealed the following findings: (1) In the first group, a minor increase in the number of modular solutions was found while they progressed along the stages; (2) The number of modular solutions of the second group was higher than of the first group. Analysis of students' justifications for lack of modularity in the first group revealed the following. The first stages of the problem were perceived as rather simple hence many students did not find any reason to invest in designing a modular solution. When the assignment got complex in the following stages, the students realized that a modular solution would fit better, hence a cognitive dissonance was raised. Nevertheless, many of them preferred to decrease the dissonance by continuing their course of non-modular solution instead of re-designing a modular new one. Students of both groups also attributed their non-modular code to lack of explicit criteria for the evaluation of the code quality that lead them to focus on functionality alone.

The effect of evolutionary algorithm in gene subset selection for cancer classification
Статья научная
The fact that reflects the cancer research consequences shows that still there are improvements that should be investigated in the stream of cancer in future. This leads the researchers to actively involve further in cancer research field. As an invention, a hybrid machine learning method is proposed in this study where two filters are assessed along with a wrapper approach. Typically, filters prioritize the features while, wrappers contribute in subset identification. Though both filters and wrappers exist independently, the excellent results they produce when applied subsequently. The wrapper-filter combination plays a major role in feature selection. Yet, incorporating with a best strategy for feature space analysis is crucial in this concern. Thus, we introduce the Evolutionary Algorithm in the proposed study to search through the feature space for informative gene subset selection. Though there are several gene selection approaches for cancer classification, many of them suffer from law classification accuracy and huge gene subset for prediction. Hence, we propose Evolutionary Algorithm to overcome this problem. The proposed approach is evaluated on five microarray datasets, where three out of them provide 100% accuracy. Regardless the number of genes selected, both filters provide the same performance throughout the datasets used. As a consequence, the Evolutionary Algorithm in feature space search is highlighted for its performance in gene subset selection.

Статья научная
In recent day’s huge rapid growth of corporate industries professional are based on the online marketing. These markets are associated with millions of online transactions which contain the details of the items, number of items, price and additional information like working details, salary information and personal information. The customers associated with these transactions are concerned about privacy issues. This manuscript aims to concentrates more on the additional information about the customer apart from dealing with the items. More analysis helps in knowing the sensitive information about an individual. In this article two algorithms were used, out of which first algorithm has been used to hide the sensitive information about an individual and other proposed algorithm has been used to hide the sensitive transaction information. These algorithms are proposed based on k-Anonymity and association rule hiding techniques. A novel algorithm has been proposed for association rule hiding algorithm to reduce the side effects such as Sensitive item-set hiding failure, Non-sensitive misses, extra item-set generations and Database dissimilarities along with the reduction of running time and complexities through transaction deletion.
