The issue of formative constructs, as opposed to the more frequently used reflective ones, has recently gained momentum among IS and Management researchers. Most researchers maintain that formative constructs have been understudied, and that there is paucity in methodological literature to guide researchers on how such constructs should be developed and estimated. A survey of IS research has re...

Partial least squares (PLS) regression on an L2-continuous stochastic process is an extension of the 2nite set case of predictor variables. The PLS components existence as eigenvectors of some operator and convergence properties of the PLS approximation are proved. The results of an application to stock-exchange data will be compared with those obtained by other methods. c © 2003 Elsevier B.V. ...

Analyzing information technology (IT) success factors is not a recent academic and practical interest. The last two decades have been rich in studies exploring the phenomenon of IT success/failure in both private and public organizations. However, many of the previous studies hypothesized only direct effects and did not allow more complex relationships between different categories of factors. B...

Earth Observing 1 (EO-1) Hyperion and Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) imagery were used to predict canopy nitrogen (N) concentration for mixed oak forests of Green Ridge State Forest in Maryland. Nitrogen concentration was estimated for 27 ground plots using leaf samples of the dominant tree species from each plot that were dried, ground and analyzed in the laboratory fo...

This paper adds to an important aspect of Partial Least Squares (PLS) path modeling, namely the convergence of the iterative PLS path modeling algorithm. Whilst conventional wisdom says that PLS always converges in practice, there is no formal proof for path models with more than two blocks of manifest variables. This paper presents six cases of non-convergence of the PLS path modeling algorith...

The potential effect on respondent burden is a major consideration in the evaluation of survey design options, so the ability to quantify the burden associated with alternative designs would be a useful evaluation tool. Furthermore, the development of such a tool could facilitate more systematic examination of the association between burden and data quality. In this study, we explore the applic...

Control and governance of corporate IT departments have become quite critical in organizations due to enormous size of their expenditure. Surprisingly, this topic is rarely discussed in management accounting and IS literature. In this paper, we present a research model that examines the relationship between the design and use of management control systems and their direct or indirect impact on ...

Knowledge sharing and absorption are required to achieve and sustain competitive advantage. Firms’ dynamic capabilities assist in mediating the effects of knowledge sharing and absorption on organizational innovation performance. Therefore, this study proposed a conceptual model to investigate the relationships among knowledge sharing capability, absorptive capability, dynamic capability, and o...

The application of crop residue has become increasingly important for providing a barrier against water and wind erosion and improving soil organic matter content, infiltration, evaporation, temperature, and soil structure. The objectives of this work were to: (i) estimate maize residue cover (MRC) from Landsat-8 OLI images using seven vegetation indices (VIs) and eight textural features; and (...
