The main aim of the study was to present an international comparison of Facebook intrusion and Internet penetration while examining possible gender differences. The study consisted of 2589 participants from eight countries: China, Greece, Israel, Italy, Poland, Romania, Turkey, USA. Facebook intrusion and Internet penetration were taken into consideration. In this study the relationship between Facebook intrusion and Internet penetration was demonstrated. Facebook intrusion was slightly negatively related to Internet penetration in each country.

The sample consists of 582 individuals who use SNSs. Our results suggest that as the intensity of positive emotions increases, users are more satisfied with SNSs. This applies to low and medium levels of negative emotions. On the other hand, for all levels of positive emotions, as the intensity of negative emotions increases, there is no significant effect on satisfaction. Our findings suggest the dominating effect of positive emotions over the negative ones in SNSs. We conclude with a summary of theoretical and practical implications along with suggestions for future work.

Building upon the dimensions of the SERVQUAL model, the aim of this study is to identify why hotel customers have disparate opinions regarding perceived service quality during their stays. In order to do so, we distinguish between high and low absolute priced hotels. We adopt this categorisation based on prior studies, which identify price as a strong determinant of hotel customers' perceptions and decisions. By applying qualitative data analysis methods on customer reviews from one of the world's leading online hotel reservation agencies (Booking.com), we show that absolute price has an impact on how customers perceive various dimensions of service quality. In particular, the number of positive reviews is significantly different for low and high priced hotels when examining the dimensions of tangibility and empathy. Additionally, our research reveals that the number of negative reviews also differentiates significantly for low and high priced hotels, not only for the dimensions of tangibility and empathy but also with regard to responsiveness and reliability. Based on these findings we highlight implications for researchers and practitioners and suggest future directions for research.

The aim of this study is to examine the profile of CS teachers in Greece and map it using the technique of persona. This study examines a national sample of 636 CS teachers who teach algorithms and programing in upper secondary education. The building of the persona is based on teachers' abilities and needs regarding the central aspects of their knowledge with respect to three key domains as described by the technological, pedagogical, and content knowledge (TPACK) framework. According to the results, teachers attain relatively high scores on the TPACK subscales, however they state that there is an area for improvement in their Technology Knowledge and the intersection between content, pedagogical, and technological knowledge. In addition, teachers feel that they need further training on how to incorporate technology in their teaching as well as how to teach algorithms; which are two areas that relate to pedagogical content

The basic emotions of happiness and anxiety were chosen. A sample of 182 online shoppers was used to assess the effect of privacy and trust on their emotions through personalized services, and how these emotions ultimately affect their purchase intentions. The findings indicate that privacy affects anxiety while trust affects happiness, while both emotions have significant influence on customers' intention to buy through personalized services. The study concludes with theoretical and practical implications, limitations, and future research directions.

This study aims to verify the moderating effect of experience on two types of relationships: the relationship of certain antecedents with satisfaction, and the relationship of satisfaction with intention to repurchase. Design/methodology/approach -This paper applies structural equation modelling (SEM) and multi-group analysis to examine the moderating role of experience in a conceptual model estimating the intention to repurchase. Responses from 393 people were used to examine the differences between high-and low-experienced users of online shopping. Findings -The research shows that experience has moderating effects on the relationships between performance expectancy and satisfaction and satisfaction and intention to repurchase. This study empirically demonstrates that prior customer experience strengthens the relationship between performance expectancy and satisfaction, while it weakens the relationship of satisfaction with intention to repurchase. Practical implications -Practitioners should differentiate the way they treat their customers based on their level of experience. Specifically, the empirical research demonstrates that the expected performance of the online shopping experience (performance expectancy) affects satisfaction only on high-experienced customers. Instead, the effort needed to use online shopping (effort expectancy) and the user's belief in own abilities to use online shopping (self-efficacy) influence satisfaction only on low-experienced customers. The effect of trust and satisfaction is significant on online shopping behaviour on both high-and low-experienced customers. Originality/value -This paper investigates how different levels of experience affect customers' satisfaction and online shopping behaviour. It is proved that experience moderates the effect of performance expectancy on satisfaction and the effect of satisfaction on intention to repurchase. It also demonstrates that certain effects (effort expectancy and performance expectancy) are valid for only one of the two examined groups, while only one effect (trust) is valid for both (high-and low-experienced).

A review of research conducted so far in the Greek online market demonstrates that satisfaction, self-efficacy and trust keep a prominent role in the Greek customers" shopping behavior. To increase understanding of this behavior, two parameters of the UTAUT model, performance expectancy and effort expectancy, are also incorporated. Our findings demonstrate that customers" perceptions about all the above parameters do not remain constant, as the experience acquired from past purchases increases. Moreover, the relationship of experience with self-efficacy and intention to repurchase changes, as satisfaction gained from previous purchases increases. The implications of this study are interesting not only for the Greek but also for the Meditterranean researchers and e-retailers, since the Mediterranean ebusiness market shares several cultural similarities with the Greek one.

However, the current understanding of the influence of personalization is limited. This study extends personalization literature into the area of emotions related to intention to purchase and into the context of online shopping. Responses from 182 online shoppers were used to examine the impact of personalization on customer emotions and intention to purchase. The results show that there is a direct positive association between personalization and purchase intentions. In addition, provision of personalization features in e-shops may evoke positive emotions to online shoppers but does not evoke nor mitigate negative ones. Finally, our study reports that emotions influence online shopping behavior either positively, through the formulation of positive emotions, or negatively, through negative emotions. These findings indicate that positive emotions mediate the relationship between personalization and purchase intentions. Our study concludes with a critical appraisal of our findings and a discussion of prospective theoretical and managerial implications for e-shop practitioners.

Effort expectancy, performance expectancy, trust and self-efficacy are some of the most widely used factors. An empirical study was undertaken to investigate the impact of various levels of these factors on consumer purchase intention. High levels of the above factors are shown to have highly significant impact on customers' intention to purchase. On the other hand lower levels of these factors do not have an impact on customer's intention. The paper contributes by highlighting the level where the impact of the factors is getting more significant.

However, the current understanding of the influence of personalization is limited. This study extends personalization literature into the area of enjoyment and privacy issues related to intention to purchase and into the context of online shopping. Responses from 148 online customers were used to examine the effects of personalization on enjoyment, privacy issues and intention to purchase. Results show that personalization affects positively enjoyment and intention, but has no effect on privacy. Additionally, privacy affects negatively both enjoyment and purchase intentions, while enjoyment has a positive influence on purchase intentions. This study suggests future research directions including the relation of trust with privacy, as well as different types of emotions, hedonic and utilitarian dimensions that relate with personalized services.

Data from 582 experienced online customers were used to validate the proposed model through structural equation modeling and multigroup analysis. Results show that quality of personalization, message quality, and benefits of the personalized recommendations are important in the persuasion process. Positive emotions increase the effect of persuasion on purchase intentions, contrary to negative emotions. The study extends online per-sonalization theory, offers an in-depth analysis of the persuasion process in online shopping, and provides valuable recommendations for personalized online marketing.
