Abstract The purpose of this paper is to explore the relationship between IT competence and job performance by different HR roles. A research model was formulated, based on two theories from both technology-to-performance chain (TPC) model and the HR five-roles model.

The purpose of this paper is to explore the relationship between IT competence and job performance by different HR roles. A research model was formulated, based on two theories from both technology-to-performance chain (TPC) model and the HR five-roles model. The study used multiple hierarchical regression approach, in which 122 HR professionals within 8 financial companies participated. The study found that IT competence positively influenced the job performance of the HR professional, while the net explanatory power and the impacted IT competency factors were different for different HR role. These findings contribute to research related to IT competence and an expanded understanding of the factors that improve an HR professional’s job performance by different HR roles.

Abstract The value of microfilm in preserving history is huge and cannot be measured by money. Kilgore Daily News is such a newspaper which records and inscribes important history in Kilgore City since 1930s. However, some factors, including microfilm life limit, usage abrasion, and accidental temperature change are shortening the life of microfilm. In addition, some characteristics of microfilm itself, such... The value of microfilm in preserving history is huge and cannot be measured by money. Kilgore Daily News is such a newspaper which records and inscribes important history in Kilgore City since 1930s. However, some factors, including microfilm life limit, usage abrasion, and accidental temperature change are shortening the life of microfilm. In addition, some characteristics of microfilm itself, such as needing support of microfilm reader, not allowed charging out, difficult to retrieve, block the usage and access of them to the public. Under these situations, it is a great idea to digitize microfilm and make them accessible to the public online. After consideration, DSpace is chosen to manage and publicize the content of digital microfilm. Read More Read Less

In the world in which information are produced and are importance more than before and one of the bases of decision making _ depends on having information and being available. One of the human’s procedures, to make information available is information organizing and knowledge management .So, since there have been libraries up to now that they are digital and under web, different procedures have been used to organize information. in accordance to the increasing growth of data and existing sources in web and web users need to have common perception of them, ontology has the main role in exchange of information and development of literal web to meaningful web .Also , ontology is a conceptional model which real existences models , relations between them in a special extent , explicitly. Therefore , by virtue of increasing growth of resources in digital frames and under web from one hand and increasing need of users to benefit from this resource on the other hand , the use of ontology that organize resources in these environments is needed. So, in this article, the researcher tries to inspect the procedures and different means of information organizing at digital and printed world under web by confirming the role of ontology in knowledge organizing at digital libraries.

This paper proposes an innovative combinational method how to select the number of clusters in the Classifier Selection by Clustering (CSC) to improve the performance of classifier ensembles both in stabilities of their results and in their accuracies as much as possible. The CSC uses bagging as the generator of base classifiers. Base classifiers are kept fixed as either decision trees or multilayer perceptron during the creation of the ensemble. Then it partitions the classifiers using a clustering algorithm. After that by selecting one classifier per each cluster, it produces the final ensemble. The weighted majority vote is taken as consensus function of the ensemble. Here it is probed how the cluster number affects the performance of the CSC method and how we can switch to a well approximation option for a dataset adaptively. We expand our studies on a large number of real datasets of UCI repository to reach a well conclusion. Read More Read Less
