Explaining information technology usage: A test of competing models

While much of the prior information technology (IT) research has attempted to explain users’ acceptance of new IT, recent research has focused on IT continuance or continued usage. The technology acceptance model (TAM) and the expectation–disconfirmation theory (EDT) are currently the dominant referent theoretical frameworks explaining user acceptance and continuance of IT, respectively. However, no study to date has yet empirically compared the relative ability of the two competing theories in explaining IT continuance intention. This paper fills this gap in the literature by comparing the explanatory ability of the two models via a longitudinal study of computer-based tutorial usage. Our findings confirm that both models have good explanatory power with the TAM providing a better prediction of intention. An integrated model, combining TAM and EDT, provided a marginally better explanatory power.

Alternative Time Scales and Failure Time Models

In many reliability applications, there may not be a unique plausible scale in which to measure time to failure or assess performance. This is especially the case when several measures of usage are available on each unit. For example, the age, the total number of flight hours, and the number of landings are usage measures that are often considered important in aircraft reliability. Similarly, in medical or biological applications of survival analysis there are often alternative scales (e.g., Oakes, 1995). This paper considers the definition of a "good" time scale, along with methods of determining a time scale.

Using Cost Per Use to Assess Big Deals

This presentation from the 23rd North Carolina Serials Conference discussed the Carolina Consortium's recent consortium-wide analysis of its big deal ejournal packages, with cost per use as the primary metric. This session addressed the pros and cons of cost-per-use (CPU) data and considered how consortia and individual schools should best utilize the data. Bernhardt discussed how the Carolina Consortium gathered and analyzed CPU data and the impact the examination had on determining whether individual schools cancelled, renewed, or joined big deals. Seven schools were identified as having big deals with CPU higher than desired. Of those seven, four schools chose to renew their deals, while three chose to cancel. Bucknall determined that while CPU is an important metric to analyze in making renewal and cancellation decisions, it is not the only factor.     

Using EZproxy and Google Analytics to Evaluate Electronic Serials Usage

ABSTRACT

The purpose of the study is to evaluate electronic usage statistics for Belk Library at Elon University. The Electronic Resources Office (ERO) collects usage data for all serials—both print and electronic—, ebooks, and electronic databases. This study used ezPAARSE and Google Analytics to analyze the data from our website, and we will use these data to compare our vendor statistics to get a more complete picture of how the library's electronic resources are being used.     

古代汉语中"为动用法"与使动、意动用法的区别

古代汉语的"为动"与使动、意动用法有质的不同.为动句是用"主·谓·宾"结构("S+V+M")表示了"S+为+M+V"式表示的语文关系的内容,二者是同义句式,可以共时变换;在古代汉语中"主·谓·宾"结构具有多义性;使动、意动用法的句子中主、谓、宾之间的语义关系与为动句不同;使动、意动与为动同义变换的句式结构不同.
