An exploration of factors that impact individual performance in an ERP environment: an analysis using multiple analytical techniques

Abstract: This study explores the factors that can impact individual performance when using enterprise resource planning (ERP) systems. Starting from the proposition that organizational performance depends o ...

Microstructure and fracture characteristics of spot-welded DP600 steel

Abstract: Microstructural characterization, microhardness tests, tensile shear tests, and fatigue tests of spot-welded hot dipped galvanized (HDG) DP600 steel were conducted. The effects of weld expulsion on the microstructural characteristics, mechanical properties, and fracture modes were investigated using optical microscopy, image analysis and scanning electron microscopy (SEM) together with energy dispersive X-ray spectroscopy (EDS). The hardness in the weld nugget was observed to be over two times higher than that in the base metal due to the formation of lath martensite. Fatigue tests showed a slightly lower fatigue limit for the joints with the expulsion. The crack initiation was observed to occur basically at the boundary of the weld nugget and at the interface between two sheets. The causes for the interfacial fracture (IF) were discussed in relation to the microstructure and weld parameters.

Charismatic leadership and user acceptance of information technology

Abstract: Although there is widespread agreement that leadership has important effects on information technology (IT) acceptance and use, relatively little empirical research to date has explored this phenomenon in detail. This paper integrates the unified theory of acceptance and use of technology (UTAUT) with charismatic leadership theory, and examines the role of project champions influencing user adoption. PLS analysis of survey data collected from 209 employees in seven organizations that had engaged in a large-scale IT implementation revealed that project champion charisma was positively associated with increased performance expectancy, effort expectancy, social influence and facilitating condition perceptions of users. Theoretical and managerial implications are discussed, and suggestions for future research in this area are provided.

Evaluation of deep convolutional nets for document image classification and retrieval

Abstract: This paper presents a new state-of-the-art for document image classification and retrieval, using features learned by deep convolutional neural networks (CNNs). In object and scene analysis, deep neural nets are capable of learning a hierarchical chain of abstraction from pixel inputs to concise and descriptive representations. The current work explores this capacity in the realm of document analysis, and confirms that this representation strategy is superior to a variety of popular handcrafted alternatives. Extensive experiments show that (i) features extracted from CNNs are robust to compression, (ii) CNNs trained on non-document images transfer well to document analysis tasks, and (iii) enforcing region-specific feature-learning is unnecessary given sufficient training data. This work also makes available a new labelled subset of the IIT-CDIP collection, containing 400,000 document images across 16 categories.
