Mobile payment system (MPSs) apps are accepted as a faster, reliable and feasible substitute to conventional payment systems. However, the reception of MPS has been slower than expected despite their potential and initial reach. Limited studies have investigated factors that determine consumers' brand love (BRL) towards MPSs. This study investigates the role of MPS app characteristics on consumer emotions, continued use intentions (CUI) and BRL towards MPS apps.

The theoretical underpinnings of stimulus organism behaviour consequence (SOBC) and pleasure arousal dominance (PAD) theory are utilized to conceptualize the research model. The model explains the drivers of MPS BRL. Innovativeness, perceived organization and entertainment are the stimuli. Emotion, conceptualized as the second-order construct derived from pleasure, arousal and dominance, is the organism. CUI is the behaviour exhibited, and BRL towards MPS is the consequence. A survey method is used to collect data from 317 MPS consumers, and the hypotheses are tested using a structural equation modelling approach.

Results indicate that innovativeness, perceived organization and entertainment influence consumers' emotions, which affects their CUI. Emotions and CUI shape BRL. Results also show a significant mediating role of emotion and CUI.

Limited studies have explored BRL for utility-driven apps like MPSs. The SOBC frameworks and PAD theory provide stronger explanatory powers to the complex interplay of variables that influence consumer perceptions and decisions regarding MPSs. The study provides several practical and theoretical insights into the role of emotions in the adoption of MPS apps, a hitherto understudied relationship in literature.

Increasingly brands are performing several activities on social media in order to alter consumer consumption towards their offering. However, limited studies have attempted to understand as how activities on social media influence usage intentions and brand loyalty. Thus, this study aims to examine the influence of social media marketing activities (SMMA) on brand experience and its association with continued usage intentions (CUI) and brand loyalty.

The study conceptualized a research model by using the theoretical premise of stimulus-organism-response theory. SMMA acts as stimulus, four (sensory, affective, behavioral and intellectual) elements of brand experience act as organism, and CUI and brand loyalty act as response. A survey-based questionnaire is used to collect data from 309 respondents. The hypothesized associations of research model were examined using the structural equation modeling approach.

Results of the study are in line with hypothesized associations among constructs. Results suggest that SMMA is associated with all four elements of brand experience. Also, affective, behavioral and intellectual aspects of brand experience are associated with CUI which influence brand loyalty. The moderating role of education on hypothesized association and the mediating role of organism are also confirmed.

Using stimulus-organism-response theory, this study confirms that SMMA are associated with sensory, affective, behavioral and intellectual aspect of brand experience which has not been examined so far. Also, the novel findings of study add to existing literature of SMMA, brand experience and brand loyalty. The study further contributes to literature by showing the moderation effect of education.

This study aims to discover the factors which influence user satisfaction levels and their continuous use intention (CUI) of academic library social media, and then considers how to promote and improve further work on library social media to reduce user churn and increase user satisfaction.

An updated DeLone and McLean information systems success (D&M ISS) model and the expectation confirmation model for information systems continuance (ECM-ISC) with new variables of emotions are used to examine the factors which influence user satisfaction levels and CUI of academic library social media through 445 questionnaires. Partial least squares structural equation modelling was used to analyse the data and presented in tables.

The results show that information quality, system quality and emotions affect user satisfaction and CUI, and reveal that emotions can affect that most obviously.

The WeChat public platform is mainly used in China, so the study only focuses on Chinese academic libraries. There are still limitations on the settings of observed variables which cannot cover all the causes of users’ positive and negative emotions. In addition, although the respondents of this questionnaire can represent academic library users, 445 samples are still fairly low in contrast to the great number of academic library WeChat public platform users.

This study integrates ECM-ISC and D&M ISS models, adds positive and negative emotions as new variables, to broaden the application scope of these models, and demonstrates the applicability of these two models in the fields of researching academic library social media, expanding and deepening related theories above. This also provides practical reference for academic libraries on how to improve user satisfaction and CUI of academic library social media and academic library WeChat public platforms, promoting the development of academic library social media.

This study aims to understand the factors affecting the continuance usage intention (CUI) of mHealth among the rural elderly.

An integrated model was proposed with the constructs derived from multiple models such as the unified theory of acceptance and use of technology, information system success model and expectation confirmation model. Data were collected from 400 participants who had prior experiences with mHealth services in Bangladesh. The research model was tested using the partial least squares method based upon structural equation modelling.

The findings indicated that system quality, performance expectancy, facilitating conditions and social influence were significant to the degree of confirmation and ultimately affect satisfaction and CUI. Surprisingly, service quality and information quality were insignificant.

This study has added in the field of knowledge by contributing some new thoughts and interpretations of continuance usage modelling for mHealth services. The findings may become beneficial for the government agencies, policymakers, mHealth systems developers and service providers.

As limited research was found on CUI of mHealth in the integrated view of rural elderly’s value, this research contributes to the extant literature by categorizing key factors that might support to proliferate the continuance usage of this service. Moreover, the contextualization of the related variables and integration of the existing model is theoretically original. Furthermore, because of a generic approach, the findings could be easily modified to assist other developing countries in the planning and up-take of mHealth.

The usage rate of mobile financial services (MFS) has shown an uptick since the emergence of the COVID-19 pandemic in Bangladesh. This study aims to reveal the underpinning reasons for such MFS surge and its continuance by integrating health belief model (HBM) and expectation confirmation model (ECM).

The study analyzes 529 MFS users' responses during the second wave of the COVID-19 outbreak in Bangladesh using the partial least square method.

Satisfaction is more predictive than perceived usefulness in explaining continuance usage intention. Expectation confirmation also indirectly affects continuance intention. Among the HBM constructs, the indirect effect of perceived severity on continuance intention via perceived usefulness and satisfaction is significant. Besides, the impact of self-efficacy on continuance intention is also significant. Moreover, perceived credibility significantly affects satisfaction and indirectly affected continuance usage intention via satisfaction.

The study projects boosting customers' satisfaction is critical for the successful retention of existing MFS customers. MFS service providers should emphasize the factors that amplify satisfaction. They must evaluate preadoption factors so that customers can have positive confirmation. Especially, the service providers, the policymakers and the regulators should take an active role in improving the users' self-efficacy and the system's credibility. Undertaking the MFS literacy program, installing hotline service to provide emergency help will boost users' confidence in using the system.

The study is a unique contribution in the context of Bangladesh. To the best of the authors’ knowledge, no previous MFS studies in Bangladesh explored MFS continuance usage intention during COVID-19 and beyond. Besides, the inclusion of “perceived credibility” in the framework will supplement the earlier studies conducted on this aspect.

This paper aims to empirically test the influence of brand characteristics on brand addiction, as well as the consumers’ behaviors caused by this construct.

The paper adopts a Web-based self-completion survey by achieving a total of 529 completed surveys. Then, structural equation modeling has been employed by using SPSS AMOS.

Results highlighted how the brand characteristics of self-expressiveness, innovativeness and authenticity have a positive influence on brand addiction; brand addiction leads consumers to feel emotions of irritability and to adopt obsessive and compulsive behaviors toward the brand.

Even if the choice of using a survey’s sample composed of students attending an Italian University ensures good internal validity of research (owing to the homogeneous character), the results are not generalizable (except for this population group).

The study identified two different spheres of brand addiction (one connected to the brand’s characteristics and the other to the consumers’ psychological-behavioral outcomes), along with possible strategies firms could adopt to strengthen the possibilities to transform their customers into addicted ones and to avoid/reduce the negative consequences deriving from brand addiction.

The paper provides a response to the call for more studies into the brand addiction analysis by empirically testing possible antecedents and outcomes, thus enriching the existing quantitative research focused on this concept.

This research focuses on the effect of molar concentration of CuI thin film deposited by mist atomization technique. The result shows the CuI thin film properties strongly depends on its precursor concentration. Thickness between 0.35 x 10⁴ nm - 1.60 x 10⁴ nm was obtained as the concentration increases. The increment of thickness affects the electrical properties which is the resistivity and conductivity of CuI thin film. The resistivity of about 10¹ω cm to 10³ω cm was observed in those CuI thin films. For optical properties, the absorption coefficient and optical band gap of CuI was determined by using Tauc's plot. The high absorption coefficient of 10⁶ m^-1 is observed in those CuI thin films with bandgap between 2.84 to and 2.95eV obtained in this experiment.

The aim of this paper is to respond to the call for exploring and empirically testing both antecedents and outcomes of brand addiction and compulsive buying behaviour. The focus of the study is on the food habits of young female consumers.

To test the hypotheses, a survey design gathering cross-sectional primary data from 325 female Italian consumers and a structural equation modelling have been adopted.

Findings show that brand addiction is positively influenced by consumer resilience, leading to increased life happiness and self-esteem, while compulsive buying behaviour is negatively influenced by consumer resilience and positively influenced by impulsivity. Compulsive buying is also associated with brand addiction and emotional overeating. Emotional overeating is additionally influenced by impulsivity and the control variables of enjoyment of food and loneliness. Moreover, loneliness has a negative impact on life happiness and self-esteem.

The study applies the proposed theory by Mrad and Cui (2020) on the relationship between brand addiction and compulsive buying to food consumption. Furthermore, it expands on this research by investigating consumer characteristics as determinants and behavioural outcomes.

The e-health services came up as an effective tool to mitigate effects of COVID-19 and following social distance norms. This study highlighted an issue of contentious usage intentions of e-health services among Thai older citizens. This study aims to examine the relationship of social influence (SI), information quality (IQ) and the digital literacy (DL) to contentious usage intentions.

This study follows quantitative techniques, and the sample size is 140 to analyze, that is collected from the older Thai citizens. The convenient sampling technique was used to collect the data and the items were measured by using a five-point Likert scale.

The findings of this study are having mixed results. The effect of DL and satisfaction (SAT) on continuous usage intention (CUI) is significant. The effect of IQ and SI on CUI is non-significant. The effect of IQ and SI on SAT is significant. Further, the mediating effect of SAT between IQ and CUI is non-significant. However, the mediating effect of SAT between SI and CUI is significant.

This study contributes to knowledge by empirical testing of DL and usage of the medicine. Furthermore, to the best of the authors’ knowledge, this study is one of the rare studies that incorporate technological intervention for drug usage intentions.

This study aims to investigate the relationship between brand love and brand addiction and their effects on consumers' negative behaviors with respect to excessive spending, trash-talking and the feeling of anxiety.

A sample of 352 young fashion brand consumers responded to a structured questionnaire. The resulting data were analyzed with structural equation modeling in MPlus.

While brand love and brand addiction are related concepts, their effects on negative consumer behaviors differ. In the presence of brand addiction as a mediator of brand love, brand addiction has a significant effect on the three negative behaviors, and the authors observe a suppression effect of brand love on the outcome variables, with total effects (direct and indirect) being insignificant.

The main limitation of this study was its single-country cross-sectional convenience sample.

While brand addiction could aid brands by leading consumers to spend excessively on them and trash-talk rival brands, it may also lead to increased consumer anxiety.

To the best of the authors’ knowledge, this is the first study to empirically assess the relationship between brand love and brand addiction and their effects on three distinctive negative consumer behaviors. This shows that brand love is an important antecedent of brand addiction.
