Researchers have found computer self-efficacy to be important to technology adoption. Past research has treated computer self-efficacy (CSE) as a unitary concept. This study proposes that CSE has two dimensions—individual and human-assisted. Using items drawn from the Compeau and Higgins’[CoHi95b] CSE instrument, the paper examines each dimension’s relationship to computer anxiety and perceived...

The study of individual differences and reactions to computer technologies have received substantive research attention (Compeau, Higgins, & Huff, 1999). Much of this stream of research attempts to improve our understanding of the mechanisms used by individuals in order to develop their computer-related skills (Vessey & Galletta, 1991). One of the core concepts of this stream of research is com...

Psychological research suggests that trying to avoid a negative outcome and trying to attain a positive outcome have different effects on performance (Higgins, 1997). We explored this prospect by examining free throw performance among NBA basketball players at the ends of games when the player’s team was ahead or behind in a clutch situation. Players tended to shoot worse than their career aver...

By a maximum likelihood analysis of mitochondrial DNA sequences, we examine Graur and Higgins' hypothesis of the Ruminantia/Cetacea clade with Suiformes as an outgroup. Graur and Higgins analyzed these sequences by the neighbor-joining and parsimony methods, as well as by the maximum likelihood method under the assumption that the substitution rate is the same for all sites. The Ruminantia/Suif...

A question of Jack Morava is answered by generalising the notion of Moore paths to that of Moore hyperrectangles, so obtaining a strict cubical ω-category. This also has the structure of connections in the sense of Brown and Higgins, but cancellation of connections does not hold.

We study the asymptotic properties of fracture strength distributions of disordered elastic media by a combination of renormalization group, extreme value theory, and numerical simulation. We investigate the validity of the "weakest-link hypothesis" in the presence of realistic long-ranged interactions in the random fuse model. Numerical simulations indicate that the fracture strength is well-d...

We show that the graded set of filter homotopy classes rel vertices of maps from the n-globe to a filtered space may be given the structure of (strict) globular ω-groupoid. The proofs use an analogous fundamental cubical ω-groupoid due to the author and Philip Higgins in 1981. This method also relates the construction to the fundamental crossed complex of a filtered space, and this relation all...
