An Overview of Conceptual Change Theories
- In Eurasia Journal of Mathematics, Science & Technology
, 2007
"... Conceptual change researchers have made significant progress on two prominent but competing theoretical perspectives regarding knowledge structure coherence. These perspectives can be broadly characterized as (1) knowledge-as-theory perspectives and (2) knowledge-as-elements perspectives. These pers ..."

Jacobian-free Newton-Krylov methods: a survey of approaches and applications
- J. Comput. Phys
"... Jacobian-free Newton-Krylov (JFNK) methods are synergistic combinations of Newton-type methods for superlinearly convergent solution of nonlinear equa-tions and Krylov subspace methods for solving the Newton correction equations. The link between the two methods is the Jacobian-vector product, which ..."

, which may be probed approximately without forming and storing the elements of the true Jacobian, through a variety of means. Various approximations to the Jacobian matrix may still be required for preconditioning the resulting Krylov iteration. As with Krylov methods for linear problems, successful
Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.
- Journal of Personality and Social Psychology,
, 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

can yield benefits on three counts. First, it can provide a real-life test of current theory and research on intrinsic and extrinsic motivation. Second, because the proposed model deals with an unfolding sequence, it may serve to integrate existing knowledge on intrinsic and extrinsic motivation
Cognitive Maps, Cognitive Collages, and Spatial Mental Models
- In Spatial Information Theory. A Theroretical Basis for GIS, COSIT’93
, 1993
"... Abstract. Although cognitive map is a popular metaphor for people's mental representations of environments, a it is typically conceived, it is often too restrictive. Two other metaphors for mental representations are proposed and supported, Cognitive collages are consistent with research demons ..."

demonstrating systematic errors in memory and judgment of environmental knowledge. Yet, for some simple or well-known environments, people seem to have coherent representations of the coarse spatial relations among elements. These spatial mental models allow inference and perspective-taking but may not allow

"... Mesothelioma, a malignant cancer of the pleura, is almost exclusively associated with asbestos exposure.1 What will it take to eradicate this highly preventable cancer? Despite the scientific consensus that exposure to asbestos fibres causes deadly diseases, we continue to use as-bestos in products ..."

The Elements of Computer Credibility
, 1999
"... Given the importance of credibility in computing products, the research on computer credibility is relatively small. To enhance knowledge about computers and credibility, we define key terms relating to computer credibility, synthesize the literature in this domain, and propose three new conceptual ..."

frameworks for better understanding the elements of computer credibility. To promote further research, we then offer two perspectives on what computer users evaluate when assessing credibility. We conclude by presenting a stt of credibility-related terms that can serve in future research and evaluation
Many are Called, but Few are Chosen: An Evolutionary Perspective for the Study of Entrepreneurship
"... More than a decade ago, Low and MacMillan identified three elements indispensable to an understanding of entrepreneurial success: process, context, and outcomes. Since their critique, three important advances include (a) a shift in theoretical emphasis from the characteristics of entrepreneurs as in ..."

Predictors of caregiving in adult intimate relationships: An attachment theoretical perspective
- Journal of Personality and Social Psychology
, 2001

In Phase 1, couple members completed questionnaires designed to identify attachment style differences in caregiving behavior and to explore the underlying (personal and relationship) mechanisms that lea ..."

Results revealed that social support knowledge, prosocial orientation, interdependence, trust, and egoistic motivation mediated the link between attachment style and caregiving. In Phase 2, responsive caregiving
