In social networking sites (SNSs), the user has a dual role as one produces content for both oneself and for the other users, and consumes the content produced by other users. Thus, we argue the SNS users can be characterized as prosumers. Drawing on the Uses & Gratifications approach, we further argue that voyeurism and exhibitionism are important gratifications from prosuming SNSs. We thus ex...

We present an approach to synthesising the effects of ageing on human face images using three-dimensional modelling. We extract a set of three dimensional face models from a set of two-dimensional face images by fitting a Morphable Model. We propose a method to age these face models using Partial Least Squares to extract from the data-set those factors most related to ageing. These ageing relat...

Purpose – Partial least squares (PLS) path modeling is a variance-based structural equation modeling (SEM) technique that is widely applied in business and social sciences. Its ability to model composites and factors makes it a formidable statistical tool for new technology research. Recent reviews, discussions, and developments have led to substantial changes in the understanding and use of PL...

Adoption of Social Media (SM) has been growing in an incremental manner over the past few years. In their attempt to capitalize from the large user base present on such websites, business executives have been piloting different approaches in order to gain a competitive edge and promote their products and services to consumers. Research however, has been lagging in this direction. This study exa...

This study examined the positive impact of a specific leadership style (i.e., transformational leadership) on information systems (IS) effectiveness in organizations based upon a subordinate’s perspective. Specifically, we investigated system users’ psychological mechanisms that may mediate the relationship between transformational leadership and IS effectiveness (i.e., individual and organizat...

MIS literature has not adequately addressed the measurement of electronic commerce dimensions and activities. Measures are yet to be proposed to assess the effect of trusted electronic interorganizational relationships on customer loyalty. In this paper, we present the results of a study that was a first effort toward this end. The focus of this study is to develop an instrument for measuring f...

During recent years, IT alignment research has gained considerable attention in both academia and practice. However, so far most studies focus on the strategic-to-strategic IT alignment dimension, thus omitting an integration of the strategic-to-tactical IT alignment dimension. By drawing upon assimilation and institutional theory, our research model depicts a perspective on IT project alignmen...

Use of the partial least squares (PLS) method has been on the rise among e-collaboration researchers. It has also seen increasing use in a wide variety of fields of research. This includes most business-related disciplines, as well as the social and health sciences. The use of the PLS method has been primarily in the context of PLS-based structural equation modeling (SEM). This article discusse...

Iron is an essential element used as supplement in different dosage-forms. Different time and expenditure-consuming methods introduced for detection and determination of elemental ions such as atomic absorption. In this research, two different and routine methods containing ATR-IR and atomic absorption were applied to define the amount of iron in 198 samples containing different concentrations ...

Partial least squares (PLS) estimation of path models has become very popular in IS research, as an alternative to covariance-based methods. PLS path modeling is often referred to as being useful for “predictive” applications. In this work, we investigate the predictive aspects of PLS path modeling and its relation to predictive analytics and predictive assessment. In particular, we compare it ...
