This study discusses various theoretical perspectives on abstract concept formation. Students’ reasoning about abstract objects is described based on proposition that abstraction is a shift from abstract to concrete. Existing literature suggested a theoretical framework for the study. The framework describes process of abstraction through its elements: assembling, theoretical generalization int...

This article presents a series of experiments on concept formation. These experiments compared four different categorisation rules. The rules presume that the stimuli to be classified can be modelled psychologically as points in a dimensional space (Shepard 1987, Gärdenfors 1990a, 1990b). Two of the rules are based on the assumption that there are prototypical representatives of a concept, a th...

The effects of observing a model and of providing a response rule on the-leran-ing,/itransfer, and retention of a dial-reading, numerical concept were studied in 144 third-graders. Different experimenters conducted the immediate learning procedures versus the measurements of retention. No extrinsic reinforcers were promised or dispensed. The children profited both from modeling and from rule-pr...

background: protein-protein interactions do not provide any direct information re­garding the domains within the proteins that mediate the interactions. the majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. most of the former studies focus only on interacting do­main pairs. however they do not consider the interaction...

Introduction: Resilience is an integrating concept. Many authors have explored the resilience concept, but in nursing there isn’t a real convergence, in the context of cultures and “theoretical models” adopted. The first aim was to explore if young nurses understand the concept of resilience and social capital. The second was to verify if there is a link between resilience and social capital in...

In 1987, DSM-III introduced the term delusional disorder. In so doing they gave new life to a concept that had predated but was delineated in its modern form by Kraepelin and developed most notably in France in the second and third decades of this century. While the current concept of delusional disorder is defined in a manner that distinguishes it from schizophrenia, a consideration of the evo...

Based on virtual equivalent system concept and methodology, a unified analysis of the stability and convergence of switching multiple model adaptive control (MMAC) of linear time-invariant discrete plant is presented. The main results are expressed by three criteria. Two of them are applicable to switching MMAC systems with arbitrary control strategy, arbitrary parameter estimation algorithm an...
