USER ACCEPTANCE OF INFORMATION TECHNOLOGY: TOWARD A UNIFIED VIEW

by Viswanath Venkatesh, Michael G. Morris, Gordon B. Davis, Fred D. Davis , 2003
"... Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formu ..."

acceptance model and the theory of planned behavior, the model of PC utilization, the innovation diffusion theory, and the social cognitive theory. Using data from four organizations over a six-month period with three points of measurement, the eight models explained between 17 percent and 53 percent

Maximizing the Spread of Influence Through a Social Network

by David Kempe - In KDD , 2003
"... Models for the processes by which ideas and influence propagate through a social network have been studied in a number of domains, including the diffusion of medical and technological innovations, the sudden and widespread adoption of various strategies in game-theoretic settings, and the effects of ..."

RFIDS: From Invention To Innovation Susan Foster, Helana Scheepers & Nasrin Rahmati RFIDS: From Invention to Innovation

by Susan Foster, Helana Scheepers, Nasrin Rahmati
"... Radio-frequency identification (RFID) technology was invented nearly 60 years ago during the 2 nd World War. However it has only been relatively recently that RFID technology adoption has been headlined in the popular press. With strategic business drivers such as supply chain management and e-comme ..."
Abstract - Add to MetaCart
fourphase RFID innovation diffusion adoption model which builds on Rogers (1995) innovation adoption literature. The paper will conclude with managerial implications and future directions for RFID research. Key words: RFID, business processes, Wal-Mart, EPC, active tags, passive tags, RFID innovation

An empirical investigation of continuous-time equity return models

by Torben G. Andersen, Luca Benzoni, Jesper Lund, David Bates, Menachem Brenner, Sanjiv Das, Bjørn Eraker, Ron Gallant, Rick Green - Journal of Finance , 2002
"... This paper extends the class of stochastic volatility diffusions for asset returns to encompass Poisson jumps of time-varying intensity. We find that any reasonably descriptive continuous-time model for equity-index returns must allow for discrete jumps as well as stochastic volatility with a pronou ..."

Influential Nodes in a Diffusion Model for Social Networks

by David Kempe , Jon Kleinberg, Éva Tardos - IN ICALP , 2005
"... We study the problem of maximizing the expected spread of an innovation or behavior within a social network, in the presence of "word-of-mouth" referral. Our work builds on the observation that individuals' decisions to purchase a product or adopt an innovation are strongly influe ..."

Depicting fire and other gaseous phenomena using diffusion processes

by Jos Stam, Eugene Fiume , 1995
"... Developing a visually convincing model of fire, smoke, and other gaseous phenomenais among the most difficult and attractive problems in computer graphics. We have created new methods of animating a wide range of gaseous phenomena, including the particularly subtle problem of modelling “wispy ” smok ..."

” smoke and steam, using far fewer primitives than before. One significant innovation is the reformulation and solution of the advection-diffusion equation for densities composed of “warped blobs”. These blobs more accurately model the distortions that gases undergo when advected by wind fields. We also

Accelerating the diffusion of innovations using opinion leaders

by W. Valente, Rebecca L. Davis - The Annals of the American Academy of Political and Social Science , 1999
"... ABSTRACT: Theory on the diffusion of innovations has been used to study the spread of new ideas and practices for over 50 years in a wide variety of settings. Most studies have been retrospective, and most have neglected to collect information on interpersonal communica-tion networks. In addition, f ..."

Innovation diffusion and new product growth models in marketing

by Renana Peres, Vijay Mahajan, Eitan Muller - Journal of Marketing , 1979
"... In this paper we review the diffusion modeling literature since the early 1990s and analyze how diffusion research has broadened its scope to describe the richness and phenomena related to new product growth. We focus on studies that explore six questions related to (a) the drivers of growth, (b) th ..."

INNOVATION DIFFUSION

by David Britain, Co Sq
"... I explore here the extent to which a number of linguistic innovations, characteristic of the Englishes of the South-East of England, have diffused to a rural area to the north-west of East Anglia, known as the Fens. In doing so, I assess whether diffusion models in the literature to date adequately ..."
