PurposeThe purpose of this article is to provide an insight into the determinants of customers' internet banking (IB) acceptance. Therefore, it attempts to address a research need for extending the technology acceptance model (TAM) by adding contextual factors for IB case.Design/methodology/approachA research model reflecting the effects of perceived risk (PR), perceived playfulness (PPL) and perceived behavioral control (PBC) on TAM constructs is proposed. The partial least squares (PLS) procedure is used to analyze 161 cases collected from individual IB users through a web‐based survey.FindingsThe results indicate that perceived usefulness (PU) and perceived ease of use (PEOU) are immediate direct determinants of customers' attitudes towards using IB (ATT). PU, PR and ATT determine the large proportion of behavioral intentions to use IB (BI). Although PPL positively influences only PEOU, PBC exerts positive direct effects on PEOU and PU and indirect effects on PU and ATT.Research limitations/implicationsThe study findings were obtained from the single snapshot research, the small data set covering only active e‐mail users and the participants' self‐reports about BI. Therefore, the future research should carry a longitudinal nature to show the temporal change effects, remedy the possibility of self‐selection bias with a broader research sample and validate the IB usage externally instead of self‐reported BI.Originality/valueThis study supplies the valuable information for researchers and practitioners about the effects of PR, PPL and PBC on IB adaptation behavior of Turkish customers. Furthermore, the study reveals that extended TAM could be used to provide a solid theoretical foundation of IB acceptance case.

Purpose Few studies have investigated how anxiety operates within the Unified Theory of Acceptance and Use of Technology (UTAUT) Framework. Consequently, this investigation explores the influence of anxiety on the customer adoption of online shopping based on the UTAUT. Design/methodology/approach The UTAUT's framework was extended by proposing new casual pathways between anxiety and its existing constructs (e.g. effort expectancy, performance expectancy and behavioural intentions) within the contingencies of age, gender and experience. The Partial Least Squares (PLS) technique was employed to evaluate the statistical significance of the proposed pathways by analysing 483 sets of self-administrated survey responses. Findings The results indicate that anxiety simultaneously exerts negative direct influences on performance expectancy, effort expectancy and behavioural intention constructs. While the moderating effects of age, gender and experience on the anxiety-intention link were found to be significant, there was no evidence suggesting that they moderate anxiety-performance expectancy and anxiety-effort expectancy relationships. Research limitations/implications The limitations of the current study are inherent in its design and methodology, providing some directions for future research. Originality/value This study contributes to the theory by including anxiety in the UTAUT and applying it to the online shopping context. The evidence about the significance of anxiety, with contingencies regarding age, gender and experience, supplies practical implications for online marketing strategies.

Purpose -The previous studies examining the role of subjective norm (SN), online shopping anxiety (ANX) and perceived playfulness (PPL) in predicting the consumer's adoption of online shopping yielded fragmented and inconsistent findings. Also, a high proportion of these findings assessing the regarded behaviour of consumers in the West cannot be directly applied to a cross-cultural context. The purpose of this paper is to investigate the relationships between these variables and the variables of technology acceptance model (TAM) associated with customer's online shopping intentions in an international environment. Design/methodology/approach -The research model reflecting the effects of SN, ANX and PPL on TAM constructs has been proposed. In total, 278 cases were gathered from online shoppers through a web-based survey. Structural equation modelling was used to evaluate the proposed research model in terms of path significance, overall model fit and explanatory power. Findings -It was found that PPL had positive direct effects on both perceived ease of use of online shopping (PEOU) and behavioural intentions to shop online (BI). Nevertheless, SN and ANX appeared to exert significant positive and negative influences respectfully on only PEOU. Research limitations/implications -The study findings were obtained from the single snapshot research, and the small dataset covering only actual online shoppers. Therefore, the future research should carry a longitudinal nature to show the temporal change effects and remedy the possibility of self-selection bias with a broader research sample. Originality/value -The paper provides additional insights for retailers and researchers into the effects of SN, ANX and PPL on online shopping intentions of Turkish consumers, which could be used in formulating online marketing strategies and considering future research directions.

Purpose This paper aims to investigate the relationships between self-monitoring, fashion involvement and technology readiness in the mobile shopping context. Although mobile shopping is still a novel activity in Turkish economical and social spheres, it has the potential to become an important driver of B2C electronic commerce in Turkey. Many Turkish firms have already extended their multichannel strategies by integrating a mobile channel into their pre-existing on-line and off-line channels. However, customers should be ready to actually embrace mobile commerce for the success of these strategies. Design/methodology/approach To test the proposed research hypotheses, a survey was administrated online to 284 volunteer undergraduate students, who were potential users of mobile shopping channel. The measurement items were developed by adapting and modifying the previously validated 13-item, self-monitoring, 16-item technology readiness index 2.0 and 5-item fashion involvement scales. Findings Results from a partial least squares analysis showed that the ability to modify self-presentation has a significant moderating influence on fashion involvement and technology readiness relationships. However, the moderating effect of sensitivity to the expressive behaviours of others for the same relationship was found to be insignificant. Further, fashion involvement appeared to have significant and direct influences on both technology readiness and attitudes towards mobile shopping. Finally, strong relationships between technology readiness, attitude and intentions to use mobile shopping were detected. Originality/value There has been little research effort conducted to examine the proposed relationships between the cited research variables in a non-Western country. Therefore, these study results yielded valuable insights for both theory and actual practice.

Wind energy is renewable and environment friendly. It is an alternative clear energy source compared to the fossil fuels that pollute the lower layer of atmosphere. The most important parameter of the wind energy is the wind speed. Statistical methods are useful for estimating wind speed because it is a random phenomena. For this reason, wind speed probabilities can be estimated by using probability distributions. An accurate determination of probability distribution for wind speed values is very important in evaluating wind speed energy potential of a region. In this study, first, we tried to determine appropriate theoretical pdf (probability density function) by comparing 10 pdf for the wind speed data measured for Gelibolu region. In determining proper pdf , an approach consisting of 3 goodness of fit tests and fitted graphics have been used.
