During the last decade online retail sales have been growing constantly. This growth has been possible due to different factors like online reviews. Online reviews have been proven successful in predicting different variables like trust and sales in online settings; however, the impact of online reviews on other variables like customer satisfaction has not been widely studied. Based on expectation-disconfirmation theory, this study analyzes the effect of online reviews on customer satisfaction. A set of six hypotheses were proposed and tested by using a controlled experiment. A total of 278 usable responses were obtained from a sample of college students from a major Midwest US university. Five of the six hypotheses were supported. Results indicated that expectations and perceived performance are significant predictors of disconfirmation. They also indicate that disconfirmation is a significant predictor of satisfaction. Regarding the effect of online reviews on satisfaction, results showed an indirect effect of online reviews on satisfaction mediated by expectations and disconfirmation. Results have implications for research and practice. For research, results help to increase the understanding of customer expectations formation in online settings. For practice, results give advice to sellers about how to increase customer satisfaction.

This study has investigated the effect of service quality on customer satisfaction and Word of Mouth in the grocery retail industry. The purpose of the study was to measure the dimensions of service quality and see its effect on customer satisfaction and Word of Mouth. The research question was created to investigate the aforementioned effect, expectations vs performance, How does service quality affect customer satisfaction and Word of Mouth? In order to compare expectations and perceived performance the service quality model, SERVQUAL was used. The thesis is a quantitative study and the data was collected through an online questionnaire where 106 respondents participated. The data was analyzed, both through measuring the gap score between expectations and perceived performance and also regressions were made to test the relationship of the variables. The findings of this study shows that service quality does affect both customer satisfaction and Word of Mouth. However the effect of service quality showed to affect customer satisfaction and Word of Mouth differently, where customer satisfaction had a higher explanatory power than Word of Mouth. Furthermore, the expectations exceeded the perceived performance of service quality in all the dimensions. This created a negative overall comparison gap between the expectations and performance. The comparison gap was fairly low and according to the theory it showed both customer satisfaction and positive Word of Mouth in the grocery retail industry in Luleå. The arithmetic mean which was collected from the questionnaire showed a high value of customer satisfaction and Word of Mouth even though a negative overall gap. However, it could be seen that only a few of the SERVQUAL dimensions could show a significant relationship, two with customer satisfaction and one Word of Mouth. / Denna studie har undersökt tjänstekvalitetens effekt på kundnöjdhet och Word of Mouth inom dagligvaruhandeln. Syftet med studien var att mäta dimensionerna av tjänstekvalitet och se dess påverkan på kundnöjdhet och Word of Mouth. Forskningsfrågan skapades för att undersöka den ovan nämnda effekten, förväntningar mot upplevd prestation, Hur påverkar tjänstekvaliteten kundnöjdhet och Word of Mouth? För att jämföra förväntningar och upplevd prestation användes tjänstekvalitetens modellen SERVQUAL. Uppsatsen är en kvantitativ studie och datan samlades in genom ett online-enkät där 106 respondenter deltog. Datan analyserades, både genom att mäta gapet mellan förväntningar och upplevd prestation samt även genom regressioner som skapades för att testa sambandet mellan variablerna. Resultaten för denna studie visar att tjänstekvaliteten påverkar både kundnöjdhet och Word of Mouth. Effekten av tjänstekvaliteten visade sig dock påverka kundnöjdheten och Word of Mouth på olika sätt, där kundnöjdhet hade en högre förklaringskraft än Word of Mouth. Dessutom var förväntningarna högre än den upplevda prestationen av tjänstekvaliteten i alla SERVQUAL-dimensioner. Detta skapade ett negativt jämförelse gap mellan förväntningarna och upplevde prestation. Jämförelse gapet var ganska lågt och enligt teorin visade det sig ge både kundnöjdhet och positiv Word of Mouth inom dagligvaruhandeln i Luleå. Medelvärdet som samlades in från enkäten visade ett högt värde av kundnöjdhet och Word of Mouth även om det totala jämförelse gapet var negativt. Det kunde dock ses att endast ett fåtal av SERVQUAL-dimensionerna kunde visa på en singifikant relation, två med kundnöjdhet och en Word of Mouth.

Social buying is a recent marketing innovation in which provides Pareto-improving welfare gains to merchants, consumers, and brokers. Consumers benefit from access to significant discounts on advertised products and services, the broker benefits from taking a significant cut in each transaction with very low fixed costs, and merchants are able to reduce their advertising costs, gain access to new markets and drive traffic to their stores. The phenomenal growth of social buying carries commensurate risks for brokers, including increased competition due to a lack of service differentiation and low entry barriers. The complete social buying transaction is completed over two stages: the initial online e-commerce transaction and the subsequent fulfilment transaction where the voucher is redeemed with the merchant. In order to explore the sustainability of the social buying business model, it is necessary to identify the factors which drive loyalty behaviours in social buying, as well as the interrelationships between the factors. This research proposes from the marketing literature Oliver’s (1980) expectancy-disconfirmation theory (EDT) as the main theoretical framework on which to model these relationships. EDT is then successfully synthesised with DeLone and McLean’s (2003) information systems success model to create a framework which can appropriately model both the online and traditional stages of the social buying transaction. This study contributes to the marketing literature by establishing EDT as a suitable framework for investigating social buying. It is believed that this study is the first to do so. Furthermore, it is believed this is the first study examining the social buying innovation in the South African context. / Graduate School of Business Leadership / MBA

Herzberg (1959) proposed a two-factor model, often named as two-factor theory when adopted by the following researches. Through measuring the level of dissatisfaction and satisfaction, he classified antecedents of work satisfaction into hygiene and motivator two type. While hygiene factors are variables which lead to dissatisfaction, motivators are variables correlated with satisfaction. In marketing area, Kano (1984) also proposed a similar concept, named two-way quality model. This model adopts both satisfaction and dissatisfaction concepts and, based on these concepts, he further classified quality properties into Must-be, Attractive and One-dimension three types. This implies that the separation of satisfaction with two dimensions allow researchers to understand how each antecedent functions. However, in past information system (IS) area, IS satisfaction was treated as a linear concept and measured with Likert or semantic differential scale. This approach lead to a direct consequence that identifying possible antecedents is possible but understanding the way they function is difficult. The purpose of this study is to develop a better approach to understand how different antecedents affect IS satisfaction. We attempt to adopt the confirmation concept in expectation-disconfirmation theory (EDT). Through measuring the level of confirmation (or disconfirmation) and satisfaction (or dissatisfaction), this study attempts to clarify how each antecedent generate effect under different contexts. This study attempts to achieve its purpose through a two-stage approach. We first used modified Delphi obtain various antecedents of IS satisfaction. In this stage, opinions from 29 scholars and experts resulted in 6 dimensions, contain 28 variables in total. In the next stage, we collected empirical data through survey to classify 28 variables into different types. We find the factors about the relation with user and IT are hygiene factor, e.g. system quality etc. The factors about the relation with user, IT and task are motivator, e.g. information quality etc. The factors about the relation with user, IT and organization are motivator and performance factor, e.g. management support and computer training are performance factors, MIS¡¦s service quality etc. are motivator. The result should provide insightful implications for both IS academia and practitioners.

Many U.S. hospitals have historically failed to recognize nursing as essential to quality of care. Given the relationship between the patients' experiences, measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), and government reimbursement, stakeholders now value the role of nurses in the care experience. Some hospitals have pursued Magnet designation, which is a rigorous and costly process, in order to promote patient satisfaction through nurse autonomy and retention. The purpose of this study was to understand whether non-Magnet hospitals received similar HCAHPS scores. Expectancy disconfirmation theory provides a framework to understand the components of patient satisfaction within the context of organizational structures and norms addressed by the Bourdieu theory of cultural health capital. A quantitative study was conducted using secondary data from a stratified random sample of 317 non-Magnet hospitals and a purposive sample of 317 Magnet hospitals. Chi-square tests of independence were performed; Magnet designation was significantly related to nurse communication, pain management, timely responsiveness of care, explanation of medication, and willingness to recommend. Magnet designation consistently had a higher proportion of 3-star and 4-star ratings compared to the tendency of non-Magnet hospitals to be more normally distributed across all five ratings. Study results, combined with the climate of patient consumerism, provide the social impetus for healthcare improvement specialists to promote social change through Magnet-like culture and protocols using an evidence-based practice outcome approach to champion better care experiences through empowerment of both patients and nurses to match expected care with delivered care.

Abstract The main focus of this study is the identification of factors influencing the use and effectiveness of information system development methodologies (Le., systems development methodologies) in health information systems. In essence, it can be viewed as exploratory research, utilizing a conceptual research model to investigate the relationships among the hypothesised factors. More specifically, classified as behavioural science, it combines two theoretical models, namely the Unified Theory of Acceptance and Use of Technology and the Expectancy Disconfirmation Theory. The main aim of behavioural science in information systems is to assist practitioners (Le., social actors) in improving business processes and competitiveness, thus the effective use of information systems. A wider view of behavioural science incorporates other social actors (e.g., end users) and organisational actors (e.g., executives). In health information systems, the effective use of information systems is especially relevant Health information systems are vital in the area of health care, since only by having access to pertinent health information, can the correct decisions relating to diagnostics and curative procedures be made. The use of systems development methodologies in health information systems development is therefore crucial, since they can make the development process more effective, while improving software quality. By empirically evaluating the conceptual research model, utilizing a survey as the main research method and structural equation modelling as the main statistical technique, meaningful results were obtained. Focussing on the factors influencing the individual's behavioural intent, it was found that the compatibility of systems development methodologies to the developer's pre-existing software development style is vital. Furthermore, performance expectancy, self-efficacy, organisational culture, policies, customer influence, voluntariness and facilitating conditions, all directly influenced the use of systems development methodologies, with policies and customer influence playing a significant role, especially in relation to health information systems. No significant direct effects or indirect effects could be established for the factors effort expectancy, personal innovativeness and social influence. It appears that individuals working in the health care software development discipline are more autonomous, less influenced by others. Also, the lack of support for the factor effort expectancy may indicate that systems development methodologies have entered a mature state, with less concern on the effort required for use. Furthermore, with regard to effectiveness and the continued use of information systems methodologies, satisfaction had a significant direct effect, with confirmation having a significant indirect effect.

Is proposed a theoretical model that seeks to measure the phenomenon suited to the needs of public organizations that offer distance learning course with the use of virtual platforms for employees. The research was conducted from a quantitative analytical approach, via online survey in a sample of 343 employees of 2 public organizations in RN who have had e-learning experience. The strategy of data analysis used multivariate analysis techniques, including structural equation modeling (SEM), operationalized by AMOS? software. The results showed that quality, quality disconfirmation, value and value disconfirmation positively impact on satisfaction, as well as disconfirmation usability, innovativeness and optimism. Likewise, satisfaction proved to be decisive for the purpose of continuance intention use. In addition, technological readiness and performance are strongly related. Based on the structural model found by the study, public organizations can implement e-learning services for employees focusing on improving learning and improving skills practiced in the organizational environment / Este estudo busca investigar os construtos da Escala de Prontid?o Tecnol?gica (TRI) e da Teoria da Desconfirma??o da Expectativa (EDT) como determinantes da satisfa??o e da inten??o de continuidade de uso em servi?os de e-learning. ? proposto um modelo te?rico que busque mensurar o fen?meno adequado ?s necessidades das organiza??es p?blicas que oferecem cursos de capacita??o ? dist?ncia com uso de plataformas virtuais para seus funcion?rios.
