Theoretical framework for a comprehensive model of end user acceptance

Numerous previous studies in the area of user acceptance have proposed several models of user acceptance. These studies have each investigated different components of the user acceptance model. No significant research has been accomplished to combine factors which influence user acceptance into one overall model, which then could be subject of further validation. The purpose of this paper is to provide the foundation for a comprehensive model of user acceptance by building a theoretical framework that brings together individual models of user acceptance

INTERRELATIONSHIPS BETWEEN USERS AND SYSTEM FLEXIBILITIES WITH PERCEIVED USABILITY OF ONLINE AIRLINE RESERVATION SYSTEMS

It is very critical for the organizations to design flexible systems that are easy to use and can accomplish all the requirements by way of offering customizability. Philosophers argue that users are good in adapting the systems; however, research shows users dissatisfaction with existing Online Airline Reservation Systems in terms of task completion. Therefore, researchers are eager to find out ways for improving online usability of the systems, how users' Perceived Usability of the system is formulated by its flexibility functions. This research therefore examines travelers' expectations, preferences and online behavior (Users' Flexibility) and aligns that with designing of flexible online airline reservation systems (System's Flexibility) and users' as evaluators of the online systems to determine its Perceived Usability through users' effectiveness, efficiency and satisfaction (Perceived Usability). In this dissertation, both quantitative and qualitative techniques were used to analyze the data collected in the context of SF, lJF and PU of the systems. A redesign solution for enhanced usability was developed based on HCI guidelines and the flexibility tactics used in online travel agencies, which led to a proposed interface with the integration of opaque mechanism. The two interfaces were used in the experiment. Participants were requested to complete the evaluation of the existing and proposed interfaces. The findings suggested that users can be classified on the basis of their Flexible Traveling Behavior which led to the development of a Users' Flexibility measuring scale. It is further investigated that integration of opaque fares concept would increase the usability of the system. Since flexibility is referred to its ability to respond to internal or external changes, systems incorporated with opaque fares would serve the role of external change agent by way of providing flexibility in users' decision making and will also serve the role of internal change agent by way of providing the capability of accepting changed decisions

Effect of Trust in Metaverse on Usage Intention through Technology Readiness and Technology Acceptance Model

The fourth industrial revolution enhanced the development of information technology in all fields and opened up possibilities. A lot of attention is focused on the future possibilities opened up by the metaverse, the core of information technology. Metaverse will have a big impact on reality and the near future. Metaverse is a virtual world that fuses physical and digital reality. Various commerce such as healthcare, instruction, business, and land are foundation to utilize metaverse knowledge in their regular work. There is a series of processes in the stage where newly developed technology is introduced to general users. In order for a new technology to become a user-friendly technology, it is necessary to verify the technology. It can be said that it is hard to derive the operator\u27s usage intention in a state where user trust for new technology is not verified. In the metaverse environment, it is necessary to first verify the trust for new technologies. This study is expected to understand usage intention through the process of checking trust in metaverse, and to become basic data for the popularization of metaverse knowledge. The meaning of this research is to inspect the influence relationship of trust in metaverse on usage intention through Technology Readiness (TR) and Technology Acceptance Model (TAM). Statistical package (SPSS23.0) was used for basic numerical examination of the questionnaire. Hypothesis test was performed using the structural equation package Smart PLS 3.0. Discriminant validity and concentration validity of the questionnaire were verified. As parameters that trust in metaverse effects, TR and TAM were set. As factors constituting TR, it was separated into optimism, innovativeness, discomfort, and insecurity. The TAM is separated into perceived usefulness and perceived ease of use. The outcomes of the study are as follows. First, trust in metaverse had a significant effect on TR. Second, TR was partially adopted in the TAM. Innovativeness and perceived usefulness had no significant effect. Third, TAM significantly influences usage intention. Fourth, perceived ease of use did not significantly influence perceived usefulness

Evaluating the Success of Lodging Yield Management Systems

Although there are more than 7,000 properties using lodging yield management systems (LYMSs), both practitioners and researchers alike have found it difficult to measure their success. Considerable research was performed in the 1980s to develop success measures for information systems in general. In this work the author develops success measures specifically for LYMSs

Knowledge Management and Sustainable Agriculture:the Italian Case

The contemporary knowledge-based economy requires global usage of information in all aspects of modern society. Pertinent information is an important asset for successful business, therefore an application of knowledge management in organisational practice has become a crucial factor for the viability and sustainable development of enterprises. This is particularly relevant for the agricultural context, which needs modern practices for enhancement and development. However, information and knowledge, due to their intangible character, seem difficult to manage and organize. Therefore the paper targeted at developing sustainable organizational model of knowledge management for small and medium enterprises. Italian agriculture is considered as a context for this study, and knowledge management was offered as a tool for facilitating agricultural performance and increasing competitiveness of agricultural sector. A wide concept of knowledge management and specified agricultural context require a theory-based approach to research and a survey. Thus, the research methodology includes the next four parts. The first one contains literature review and examines definitions, strategies, approaches and models of sustainable knowledge management. The second part includes content analysis of 105 scientific publications. The third part of methodology is based on the results of the two previous parts and includes creating the model of knowledge management. Verification of this model is the last part of the research. Verification was executed through on-line questionnaire distributed to Italian agricultural enterprises throughout the country on their intentions and awareness towards knowledge management and developed model of knowledge management. The results of the survey have demonstrated farmer’s incentives to implement the developed knowledge management model with flexible approach in its organisation

USER INFORMATION SATISFACTION: TOWARD CONCEPTUAL CLARITY

User information satisfaction (UIS) has been generally recognized by management information systems (MIS) researchers as one of the more important indicators of success in designing and implementing MIS. However, the existence of various UIS measures using different definitions of UIS has resulted in the use of inconsistent theoretical constructs and an inability to interpret across studies. Using consumer satisfaction research as a reference theory, this paper develops a conceptual model of UIS to clarify the concept. In the model, UIS is considered a function of organizational factors and the discrepancy between expected information service quality and perceived information service quality. This discrepancy, in turn, is a result of a series of gaps which are related to the MIS development and information service delivery processes. The implications of this model for future research and practice are discussed

Factors determining the behavior and effectiveness of personal decision support systems users: An examination of Fishbein\u27s model

Personal computing, and the microcomputer which support it, are referred to as Personal Decision Support Systems (PDSS) (Lehman, 1985). Empirical studies regarding personal computing have been of the general field study type, primarily examining trends and/or establishing the basic concept of personal computing. This research builds and empirically tests a research model that conceptualizes some impact variables which are internal to the user, as intervening in the relationship between the situational or external variables identified by previous MIS research and system success (utilization, decision performance, and satisfaction). This study employs a framework, based on Fishbein and Ajzen\u27s intention-behavior model (1975), to integrate variables indicated to be important by previous findings in MIS studies, and to provide a micro-description of how those variables affect success of personal DSS. The conceptual model consists of six independent variables (users\u27 experience and education, enduser tools, end-user support, end-user training, task fepetitiveness, and task analyzability) and their impact on three intermediate variables (attitude, intention, and actual usage) and one dependent variable (user satisfaction). j The methodology employed in this study involves a two-phased cross-sectional field survey of personal DSS users in seven large organizations. To examine the mechanisms by which the independent and intermediate variables affect success, eight hypotheses were investigated using stepwise multiple regression analysis. Three hypotheses were supported. Although the study failed to shed light on how the determinants a//ecf success, it co^irmed the underlying conceptual framework of Fishbein\u27s model
