Environmental stimuli and user experience in online customer communities : a focus on flow and behavioural responseAuthor Mercy MpinganjiraSource: Management Dynamics : Journal of the Southern African Institute for Management Scientists 25, pp 2 –16 (2016)More Less
Providing a compelling consumer experience is one of the major concerns of marketers. In the online context, provision of such an experience is known to depend on the facilitation of a state of flow. This study investigates flow experience in online customer community websites. Data were collected from 303 members of online customer communities using a structured questionnaire, and analysed using structural equation modelling. The results demonstrate that focused attention, time distortion, and cognitive enjoyment are distinct and significant components of flow experience in such contexts. The results also show the important role played by environmental factors - particularly web content quality and visual appeal - in influencing flow experience, which in turn affects commitment intentions. Flow experience was found to be a significant mediator of the relationship between contentquality and commitment intentions. The results point to the need for managers to examine user flow experience when working on enhancing user commitment, and some of the factors on which they can focus in trying to ensure an optimal user experience.

The Performance Index (PI) was developed as a comprehensive criterion measure of unit performance for which the unit leader could be held responsible. The basic PI structural model has been developed to explain how the various latent unit performance dimensions comprising organisational unit performance are structurally inter-related. Preliminary research suggests that the basic PI structural model might have to be refined. Continued research into this can only be justified, however, if the basic PI structural model is shown to be structurally invariant across independent samples from the target population. As a necessary methodological precursor to the structural invariance study, Dunbar, Theron and Spangenberg (2011) demonstrated that the PI measurement model successfully cross-validated across two independent samples from the same population, and thus may be considered measurement invariant. A non-hierarchical taxonomy of structural invariance is proposed that distinguishes between five forms of structural invariance. Gamma, beta, phi, and psi invariance is obtained for the PI structural model. Suggestions for further research are made.

This study examined the effect of hedging with derivatives on the value of a sample of the 40 largest non-financial firms listed on the Johannesburg Stock Exchange (JSE) from 2008 to 2012. It applied a univariate and a multivariate approach to determine the effect of using derivatives on firms' Tobin's Q, performance indicators such as return on assets (ROA) and return on equity (ROE), and indicators of firm value such as economic value added (EVA), market value added (MVA), and the market value of shares. The results of these analyses indicate that the use of derivatives had no significant impact on firm value, but there was a significant association between using derivatives, MVA, and the market value of shares. Previous international studies found divergent results on the effects of derivative hedging strategies on firm value. The findings from this study support those studies that found no value premium, and suggest that hedging with derivatives is not a value-adding strategy for South African firms. Further research is needed to examine the extent and effectiveness of the use of derivatives by firms in South Africa.
