The Effects of Knowledge Transfer On Complex Problem Representation and Judgment in Auditing
… an auditor’s ability to form an appropriate problem representation, which in turn impacts judgment performance. One of the key components of this process is having sufficient knowledge for purposes of problem representation; without it, the auditor’s problem representation and ultimately …

Hooking the big idea: Working titles in creative problem solving by young Latino adolescents
Problem representation/problem finding skills are frequently the catalyst facilitating adroit knowledge base access and subsequent positive creative outcomes in adult populations. To determine whether judged creativity is similarly enhanced through young adolescents' use of a working title …

Representing the problem of learning to teach: Student teachers’ definitions of learning, teaching and the student teacher role
… the teacher is to assume a role primarily as a problem solver it may require a different approach than the current, largely theoretical and fragmented approach. Teachers and student teachers identify the practicum as the most valuable aspect of teacher education, possibly because of the …

The Proteomics Approach To Evolutionary Computation: An Analysis Of Pr
… increases, so does the complexity of the problems that we approach using evolutionary search techniques. There are recent approaches to deal with the problem of scaling evolutionary methods to cope with highly complex difficult problems. Many of these approaches are biologically inspired …

Defining the Problem: Towards an Understanding of Organizational Decision-Making
… their advisors. It portrays the decision makers' problem representation as consisting of their interpretation of the organization's goal and specific elements of the advisors' proposed solutions. The decision to implement a specific solution, in turn, was based on the compatibility between a …

A neo-piagetian perspective on student teachers’ representations of the real life teaching problem: adapting instruction to individual differences among learners
… teachers represent the real life teaching problem of adapting their instruction to individual differences among learners and how their representation changes over the course of the practicum experience. The extent to which Cases' (1985, 1991) neo-Piagetian conceptual framework may describe …

Walsh analysis, epistasis, and optimization problem difficulty for evolutionary algorithms
… bit strings of length L. Epistasis is related to problem difficulty for evolutionary algorithms. Walsh analysis can be used to quantify epistasis. In this dissertation Walsh analysis is developed in detail starting with the definitions for the Walsh transform. The epistasis of a polynomial is …

A multiscale approximation algorithm for the cardinality constrained knapsack problem
… for the cardinality constrained knapsack problem. The algorithm consists of three steps: a rounding and reduction step where a hierarchical representation of the problem data ranging from coarse to fine is generated, a solution step where a coarse solution is computed, and a refinement …

CHARTMAKER: a "true consultant" expert system for designing charts
… heuristic classification. These systems solve problems of a type determined by the knowledge engineer and the expert at system design time. A "true consultant" on the contrary, applies domain knowledge to solve a problem not previously seen. For example, a graphic design consultant must accept …

An investigation into the use of software-defined networking controllers
… small size to leverage a highly parallelizable problem representation and solution. This algorithm solves the problem of deciding which directional antennas to align to form connections and efficiently processes frequent updates while generating an exact solution for the optimal path.

Support for Gestalt Versus Business-As-Usual Theories of Insight Depends on Operational Definition of Insight
… of “Aha!” experiences and impasse in insightful problem solving. One hundred two undergraduate psychology students from Old Dominion University completed working memory tasks, six classic insight problems, and gave initial problem representation ratings for the insight problems before solution …

Exploiting machine learning for combinatorial problem solving and optimisation
… in particular for combinatorial search problems. We propose a novel hierarchical portfolio which does not rely on a single problem representation, but may transform the problem to an alternate representation using a portfolio of encodings, additionally a portfolio of solvers is employed …

Are cognitive and social factors sufficient to explain the acceptance of decision aiding processes within organisations?
… in which the decision aid represented the basic problem, and this was argued to form the cognitive and social/actors. The expectation was to find an association between the level of intra-organisational agreement and either acceptance or rejection of the decision aid if they are the sole cause. …

The restructuring of the professional knowledge base of teachers in England 2010-2024
… actors as the solution to a potent problem representation in this period – that teachers are teaching ineffectively, and therefore are not being the agents of social mobility they could otherwise be. That is, these knowledges are positioned as mechanisms through which a meritocratic …

Systematic synthesis of sloppy multicomponent separation sequences
An important process-design problem in multicomponent separations is separation sequencing, which is concerned with the selection of the best method and sequence for a separation system. Essentially all of the published work on this subject has been limited to high-recovery or sharp separations, in …

Robust scheduling control of aeroelasticity.
