An exploration of affect factors and their role in user technology acceptance: Mediation and causality
Wiley - Tập 59 Số 8 - Trang 1252-1263 - 2008
AbstractAffect factors have gained researchers' attention in a number of fields.
The Information Systems (IS) literature, however, shows some gaps and
inconsistencies regarding the role of affect factors in human–computer
interaction. Building upon prior research, this study aims at a better
understanding of affect factors by clarifying their relationships with each
other and with other primary us...
Bounded rationality and satisficing in young people's Web‐based decision making
Wiley - Tập 53 Số 1 - Trang 16-27 - 2002
AbstractThis study investigated Simon's behavioral decision‐making theories of
bounded rationality and satisficing in relation to young people's decision
making in the World Wide Web, and considered the role of personal preferences in
Web‐based decisions. It employed a qualitative research methodology involving
group interviews with 22 adolescent females. Data analysis took the form of
iterative p...
Judgment of information quality and cognitive authority in the Web
Wiley - Tập 53 Số 2 - Trang 145-161 - 2002
AbstractIn the Web, making judgments of information quality and authority is a
difficult task for most users because overall, there is no quality control
mechanism. This study examines the problem of the judgment of information
quality and cognitive authority by observing people's searching behavior in the
Web. Its purpose is to understand the various factors that influence people's
judgment of qu...
Overlap in bibliographic databases
Wiley - Tập 54 Số 12 - Trang 1091-1103 - 2003
AbstractBibliographic databases contain surrogates to a particular subset of the
complete set of literature; some databases are very narrow in their scope, while
others are multidisciplinary. These databases overlap in their coverage of the
literature to a greater or lesser extent. The topic of Fuzzy Set Theory is
examined to determine the overlap of coverage in the databases that index this
topic...
Duality revisited: Construction of fractional frequency distributions based on two dual Lotka laws
Wiley - Tập 53 Số 10 - Trang 789-801 - 2002
AbstractFractional frequency distributions of, for example, authors with a
certain (fractional) number of papers are very irregular and, therefore, not
easy to model or to explain. This article gives a first attempt to this by
assuming two simple Lotka laws (with exponent 2): one for the number of authors
with n papers (total count here) and one for the number of papers with n
authors, n ∈ ℕ. Base...
The power of power laws and an interpretation of Lotkaian informetric systems as self‐similar fractals
Wiley - Tập 56 Số 7 - Trang 669-675 - 2005
AbstractPower laws as defined in 1926 by A. Lotka are increasing in importance
because they have been found valid in varied social networks including the
Internet. In this article some unique properties of power laws are proven. They
are shown to characterize functions with the scale‐free property (also called
self‐similarity property) as well as functions with the product property. Power
laws hav...
Relations between the continuous and the discrete Lotka power function
Wiley - Tập 56 Số 7 - Trang 664-668 - 2005
AbstractThe discrete Lotka power function describes the number of sources (e.g.,
authors) with n = 1, 2, 3, … items (e.g., publications). As in econometrics,
informetrics theory requires functions of a continuous variable j, replacing the
discrete variable n. Now j represents item densities instead of number of items.
The continuous Lotka power function describes the density of sources with item
d...
The effect of social network sites on adolescents' social and academic development: Current theories and controversies
Wiley - Tập 62 Số 8 - Trang 1435-1445 - 2011
AbstractTeenagers are among the most prolific users of social network sites
(SNS). Emerging studies find that youth spend a considerable portion of their
daily life interacting through social media. Subsequently, questions and
controversies emerge about the effects SNS have on adolescent development. This
review outlines the theoretical frameworks researchers have used to understand
adolescents an...
Intended and unintended consequences of a publish‐or‐perish culture: A worldwide survey
Wiley - Tập 63 Số 7 - Trang 1282-1293 - 2012
How does publication pressure in modern‐day universities affect the intrinsic
and extrinsic rewards in science? By using a worldwide survey among demographers
in developed and developing countries, the authors show that the large majority
perceive the publication pressure as high, but more so in Anglo‐Saxon countries
and to a lesser extent in Western Europe. However, scholars see both the pros
(up...
Gender and Web information seeking: A self‐concept orientation model
Wiley - Tập 57 Số 8 - Trang 1105-1115 - 2006
AbstractAdapting the consumer behavior selectivity model to the Web environment,
this paper's key contribution is the introduction of a self‐concept orientation
model of Web information seeking. This model, which addresses gender, effort,
and information content factors, questions the commonly assumed equivalence of
sex and gender by specifying the measurement of gender‐related self‐concept
traits...
