introduction: this in vitro study investigates the marginal and internal fit of indirect class ii composite restorations. two different processes for chair-side restorations were compared. in group a, the restorations were fabricated using cad/cam technology (cerec, sirona, germany, bernsheim) and in group b they were made by hand (grandioso inlay system, voco gmbh, germany, cuxhaven). methods:...

In this paper, we propose a theory of task/technology fit for mobile applications to support organizational processes (tasks). We adapt the concept of task/technology fit developed by Zigurs and Buckland (1998) and Goodhue and Thompson (1995), to account for the fact that mobile applications, as a type of IT infrastructure, potentially cover a wider area of tasks than the specific applications ...

Decisions are often based on the results of quantitative analysis. To gain confidence in these results, some indication of their quality is needed. Measurement uncertainty, as proposed by the International Organization for Standardization (ISO), is a way to express this quality. Most measurement techniques compare references and therefore need to be calibrated. Usually least squares methods ign...

In an attempt to provide a causal model for Information Technology (IT) acceptance, this research integrates task-technology fit and social influence perspectives. This research model includes simultaneously IT acceptance variables, antecedents of IT acceptance, and its impact on individual performance. The implicit assumption between IT acceptance and its positive impact is empirically tested....

Hospitals transitioning from paper to electronic information systems often find inadequate fit between newly implemented technology and work environment causing delays, inefficient use of resources and new kind of errors attributable to problems in human interaction with computer systems. The purpose of this study is to characterize the workflow, decision making and cognitive processing of clin...

Increasingly, e-books are becoming alternatives to print books in academic libraries, thus providing opportunities to assess how well the use of e-books meets the requirements of academics. This study uses the task-technology fit (TTF) model to explore the interrelationships of e-books, the affordances offered by smart readers, the information needs of academics, and the "fit" of technology to ...

Ubiquitous Information Systems (UIS) embedded in everyday environments are required to provide means for supporting complex behavioral task requirements. With the concept of a situation, we propose a knowledge level that can be used by users for understanding UIS-enhanced environments. It is discussed how the concept of situation differs from the concept of context. Situations are used to ident...

this study aims to examine how open innovation can be effective in changing organizational inertia to create business model innovation and improve firm performance. it also seeks to explore whether the existence of open innovation has a mediating effect and influence. this study constructs a theoretical model to explore the relationship between latent variables and uses a questionnaire to colle...
