Partial least squares (PLS) is a widely used method for prediction in applied statistics, especially in chemometrics applications. However, PLS is not invariant or equivariant under scale transformations of the predictors, which tends to limit its scope to regressions in which the predictors are measured in the same or similar units. Cook et al. (2013) built a connect between nascent envelope m...

Social Media has been gaining popularity worldwide over the last years at an increasingly growing rate. Motivated by this fact, firms are piloting different approaches of promoting their products and services to consumers in order to capitalize on the prominence of such websites. However, there is much debate in the academic and business community about the potential of social media as a platfo...

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...
