Still, the investigation of the most effective mix of key design elements in Instagram ads in relation to consumer purchase intention and brand image is still under-explored. This study aims to examine the impact of three key advertisement design elements (colour, font size and layout) on brand image and consumer purchase intention. Three hundred twenty participants were randomly assigned to the conditions of the experiment. The findings provided insights into the way the design elements alter the intention of the consumers to buy and their perceptions of the brand image respectively.

We used a questionnaire consisting of the following sections: demographics, SCOFF questionnaire for screening EDs, the Achievement Anxiety Test (AAT) and the Depression, Anxiety and Stress Scale (DASS). Our sample was selected randomly. Sample size was 535 students (44% men, 56% women), and 33% of students were between 18 and 20 years old (age range 16–28).ResultsSCOFF's reliability measured by Cronbach's alpha was 0.542; AAT's alpha for its facilitating scale was 0.682 and debilitating scale 0.821; finally, DASS's depression, anxiety and stress sections’ alpha were 0.923, 0.896 and 0.876 respectively. The prevalence of EDs was 42.2%. The associated factors with the presence of EDs was gender (62% women, 38% men; X2 = 5.007, p = 0.025) and personal family status (X2 = 18.862, p = 0.002), while having divorced parents was a borderline association (OR = 1.53, 95% CI 0.97–2.42). Mann-Whitney’s U test showed that there was a significant difference in the scale of stress between those with an ED and those without (p = 0.026) but not for depression and anxiety. According to multiple logistic regression, risk factors for having an eating disorder were depression, stress, female gender, being married and searching for a romantic relationship (overall model fit p < 0.0001).ConclusionThis is the first study on EDs from Greece. Depression and stress were significant predictors of EDs, which shows the importance of these two factors in the pathogenesis of EDs.

Research shows that the performance of hotel service attributes is expected to have asymmetric effects on customer satisfaction. The purpose of this study is to analyze online reviews and determine whether different hotel service attributes have asymmetric or symmetric effects on hotel customer satisfaction and how these effects differ for different customer segments. Positive and negative comments on hotels are analyzed using three-factor theory and penalty-reward contrast analysis. Results show that the most important service attributes for customer satisfaction and dissatisfaction (hybrids) are location/access and personnel quality. All other attributes are either frustrators (cleanliness, process quality, perceived value) or dissatisfiers (installation quality, room quality, food quality). However, when the sample is split into business (solo and groups) and leisure (solo, groups, families, couples) results differ by customer segment. Results show that there should be a customized approach to managing customer satisfaction based on online reviews where service attributes are prioritized differently according to their importance for the satisfaction of different customer segments.

The personality of businesses and destinations is analyzed by various researchers. The purpose of this study is to analyze the Brand Personality of Athens as a destination from the tourist’s perspective. A survey was conducted with a sample of tourists in 2018. A structured questionnaire in English was distributed to tourists in a central area of Athens. A total of 118 valid questionnaires were collected and analyzed with SPSS. Results show that on the whole tourists are mostly positive and moderate in their evaluation of brand personality of Athens. Athens scores higher in the Charming dimension and is described as particularly cool, imaginative and sentimental. On the other hand, while the dimension Outdoorsy gets the lowest score Athens is perceived as wholesome. Furthermore, tourists feel that the brand personality of Athens lacks in the excitement dimension, especially in the exciting, original and cheerful characteristics whereas the best score in this dimension is young and spirited. Finally, the competence dimension shows that Athens is particularly feminine, friendly and intelligent but needs to be supported to enhance the characteristics of successful, confident and smooth. This study serves as a guide to the city of Athens in managing brand personality. Future research can extend the sample and provide a more detailed analysis of the Athens brand personality.

An extended version of the Unified Theory of Acceptance and Use of Technology (UTAUT), a model that incorporates the most relevant theoretical approaches in the adoption literature was selected to investigate the consumers' adoption process. To empirically test the proposed model, data were collected from 513 consumers of mobile internet service providers in Greece and were analyzed using PLS. The results indicated that p-mps features, expressed by consumers' expectations about service performance and required efforts, along with the social context effects have the biggest impact on consumers' intentions to use the service, followed by channel characteristics, reflecting consumers' beliefs about p-mps usage risk and trust. Potential customers' characteristics moderating analysis suggested that the effects of performance expectancy and perceived trust on behavioral intentions are affected by gender, age and previous experience, while that of social influence only by potential customers' previous experience. Theoretical and managerial implications, limitations and suggestions for further research are provided at the end of the study.

Though there is growing evidence that the relationship between service performance and satisfaction is asymmetric, there are no studies investigating the nature of this relationship in the context of primary healthcare services and how this is affected by patients' characteristics. The purpose of this study is to exploit the framework of the three-factor theory to distinguish between different types of quality attributes, and then to explore possible deviations from the aggregated quality attributes' classification pattern for patients with different demographic characteristics. The results of an empirical study, concerning 407 service users, confirmed the asymmetric relationship between identified attributes' performance and patient satisfaction and revealed three attributes' classification patterns for different patient characteristics. Implications for practice and directions for future research are then discussed.

Based on a two-stage hybrid analytic methodology, the proposed model was validated empirically using a sample of 951 participants. First, partial least squares (PLS) regression was used to identify the significant drivers of PMPS acceptance predictors. Artificial neural networks (ANN) were then used to rank the relative influence of the significant adoption drivers obtained in the previous step. The PLS results indicate that the extended DTPB provides a solid theoretical framework for studying the adoption of PMPS. The results of the PLS-ANN sensitivity analysis confirmed the PLS results regarding the importance of the determinants' of normative and controlling customers’ beliefs, although there were some contradictions concerning the determination of customer attitudes and behavioural intentions towards PMPS usage. The results are discussed and implications are offered.

Design/methodology/approach-On evidence drawn from 1,016 consumers of wireless-enabled computing devices (e.g. netbooks and tablets) in Greece, partial least squares method is used to test the validity of the proposed hierarchical model. Findings-Results show that a lovemark measure can be conceptualized as a third-order reflective construct having respect and love as its second-order dimensions. In turn, respect reflects on brand performance, trust and reputation, and love reflects on brand commitment, intimacy and passion. The proposed measure presents a very good external validity as it can explain big portions of variance in consumer responses including repurchase intentions, positive WOM and willingness to pay a price premium. Finally, the proposed measure is used to classify eight well-known devices as products, fads, brands and lovemarks and identify the love styles associated with brand relationships. Originality/value-This paper provides empirical evidence for measuring and identifying lovemarks using a hierarchical model, which can be further used to develop a more effective strategy

The stochastic model is solved analytically by using the theory of reducible stochastic differential equations and the first moment of the resulting stochastic process is presented. The parameter estimators of the model are derived by using a procedure which provides the maximum likelihood estimators (MLE) using time series data. Finally, the model is applied to the data of electricity consumption in Greece. Using a simulation technique, it is possible to predict the performance of the consumption process by defining a subdomain to which all possible trajectories of the process should belong with a predefined probability.

The model considers four drivers-perceived functional and technical aspects of service quality, emotional satisfaction and corporate image-that are positively related to each other and positively affect customer intentional loyalty. On evidence drawn from 573 service customers, the hypotheses, which were tested using structural equation modeling, are all supported. The results confirm that perceived service quality aspects, emotional satisfaction and image are key drivers of customer loyalty. The research emphasizes the role of emotional satisfaction and image as mediating variables between perceived service quality aspects and loyalty. The study also shows that a better understanding of the determinants of behavioral intentions in technologymediated services occurs when affective evaluative constructs are considered along with cognitive ones.

Specifically, three parts of marketing strategy are analysed: the communication mix used by service firms; the management of customer relationships and new service development (NSD). Results from 18 businesses in 3 service industries (fitness, tourism and education) show that only about half of the businesses employ a qualified manager for social media. However, all sample companies measure social media effectiveness. Although all participant businesses promote their offers in various social media and cultivate intimate relationships with customers, using social media for developing new services is less common and found mostly in Greek fitness centres where customers are asked to vote for ideas for new services; provide opinions on existing services, and share their ideas.

An extended version of the decomposed theory of planned behaviour (DTPB), a model that incorporates the most relevant theoretical approaches in the mobile payment adoption literature was selected to investigate the consumer's adoption process. To empirically test the proposed model's nomological validity, data were collected from 513 consumers of mobile internet service providers in Greece and were analysed using PLS. The results indicated that consumers' attitude about the NFC proximity mobile payment services is the main driver of consumers' intentions to use it, followed by their normative, control and risk beliefs. As far as the behavioural intentions determinants' structure is concerned, consumer's perception about service attributes compatibility and performance (i.e., usefulness, easiness, and reduced riskiness), the availability of knowledge, resources, and opportunities necessary for using the service and the support of the interpersonal and the external social context toward the usage of the technology found to be adoption facilitators. Theoretical and managerial implications, limitations and suggestions for further research are provided at the end of the study.

The new species superficially resembles pyrgotid flies by lacking frontal setae and wing pattern, and by having numerous proepisternal setae and brownish yellow body. It possesses a unique structure of female terminalia, which is a synapomorphy of the Tachiniscinae, and the incomplete costal vein, long tubular phallus and elongate spermathecae, which are considered synapomorphies of the tribe Tachiniscini, and is placed in that tribe.

The purpose of this study is to test the effect of respect and rapport on RQ and customer loyalty (CL) in high credence services. A survey was carried out involving a convenience sample of 500 customers of private practice medical doctors from several specialties operating in Athens, Greece. Data was analysed with PLS-PM. Results showed that rapport is the most significant antecedent of RQ followed by two dimensions of respect: responsibility and understanding. Also, respect and rapport indirectly affect customer loyalty through RQ but there is also a direct effect between rapport and responsibility and loyalty. Findings present managerial implications. Future research should validate results in multi-context or multi-country studies.
