This paper introduces the Eight Dimensional Methodology for Innovative Thinking (the Eight Dimensional Methodology), for innovative
problem solving, as a unified approach to case analysis that builds on comprehensive problem solving knowledge from industry,
business, marketing, math, science, engineering, technology, arts, and daily life. It is designed to stimulate innovation
by quickly generating unique “out of the box” unexpected and high quality solutions. It gives new insights and thinking strategies
to solve everyday problems faced in the workplace, by helping decision makers to see otherwise obscure alternatives and solutions.
Daniel Raviv, the engineer who developed the Eight Dimensional Methodology, and paper co-author, technology ethicist Rosalyn
Berne, suggest that this tool can be especially useful in identifying solutions and alternatives for particular problems of
engineering, and for the ethical challenges which arise with them. First, the Eight Dimensional Methodology helps to elucidate
how what may appear to be a basic engineering problem also has ethical dimensions. In addition, it offers to the engineer
a methodology for penetrating and seeing new dimensions of those problems.
To demonstrate the effectiveness of the Eight Dimensional Methodology as an analytical tool for thinking about ethical challenges
to engineering, the paper presents the case of the construction of the Large Binocular Telescope (LBT) on Mount Graham in
Arizona. Analysis of the case offers to decision makers the use of the Eight Dimensional Methodology in considering alternative
solutions for how they can proceed in their goals of exploring space. It then follows that same process through the second
stage of exploring the ethics of each of those different solutions.
The LBT project pools resources from an international partnership of universities and research institutes for the construction
and maintenance of a highly sophisticated, powerful new telescope. It will soon mark the erection of the world’s largest and
most powerful optical telescope, designed to see fine detail otherwise visible only from space. It also represents a controversial
engineering project that is being undertaken on land considered to be sacred by the local, native Apache people. As presented,
the case features the University of Virginia, and its challenges in consideration of whether and how to join the LBT project
consortium.

To test the relation between sluggish cognitive tempo (SCT) and DSM-IV ADHD symptoms, parent and teacher ratings of the 18 DSM-IV ADHD items and five potential SCT items were obtained in a community sample of 8-18 year-old twins that was overselected for ADHD and learning disabilities (n = 296). Confirmatory factor analyses revealed that a three-factor model provided the best fit to the data for both parent and teacher ratings. DSM-IV inattention and hyperactivity-impulsivity symptoms loaded on two factors consistent with the DSM-IV model, and five SCT symptoms loaded primarily on a third factor. The SCT and inattention factors were highly correlated, whereas SCT and hyperactivity-impulsivity were weakly related. Both raters indicated that children meeting symptom criteria for the combined and inattentive subtypes exhibited significantly more SCT symptoms than those meeting symptom criteria for hyperactive-impulsive type and the comparison group without ADHD. Children meeting symptom criteria for the inattentive type exhibited significantly more SCT symptoms than those meeting criteria for the combined type, based on teacher ratings. These results suggest that SCT is an internally consistent construct that is significantly associated with DSM-IV inattention. 相似文献

Acquiring an understanding of design: evidence from children's insight problem solving 总被引:8,自引:0,他引:8
The human ability to make tools and use them to solve problems may not be zoologically unique, but it is certainly extraordinary. Yet little is known about the conceptual machinery that makes humans so competent at making and using tools. Do adults and children have concepts specialized for understanding human-made artifacts? If so, are these concepts deployed in attempts to solve novel problems? Here we present new data, derived from problem-solving experiments, which support the following. (i) The structure of the child's concept of artifact function changes profoundly between ages 5 and 7. At age 5, the child's conceptual machinery defines the function of an artifact as any goal a user might have; by age 7, its function is defined by the artifact's typical or intended use. (ii) This conceptual shift has a striking effect on problem-solving performance, i.e. the child's concept of artifact function appears to be deployed in problem solving. (iii) This effect on problem solving is not caused by differences in the amount of knowledge that children have about the typical use of a particular tool; it is mediated by the structure of the child's artifact concept (which organizes and deploys the child's knowledge). In two studies, children between 5 and 7 years of age were matched for their knowledge of what a particular artifact "is for", and then given a problem that can only be solved if that tool is used for an atypical purpose. All children performed well in a baseline condition. But when they were primed by a demonstration of the artifact's typical function, 5-year-old children solved the problem much faster than 6-7-year-old children. Because all children knew what the tools were for, differences in knowledge alone cannot explain the results. We argue that the older children were slower to solve the problem when the typical function was primed because (i) their artifact concept plays a role in problem solving, and (ii) intended purpose is central to their concept of artifact function, but not to that of the younger children. 相似文献

A thorough understanding of Multiple Sclerosis (MS) is necessary to offer individuals informed options for treatment and planning. To assist in this quest, the following historical analysis examined how MS has been conceived from the 14th century through the early 20th century. Primary sources were consulted whenever possible, and many of the original archival materials were accessed by the first author (MB) during an on-site visit to the Rare Book Room of the New York Academy of Medicine. There is a striking similarity between how MS symptoms have presented throughout history compared with the 21st century. Sensorimotor and cognitive sequelae have been observed in patients since the 1800s. Cognitive symptoms were acknowledged in the 1800s, but disregarded in the early 1900s and were not given recognition again until the latter part of the 20th century. If conceptualizations of MS are inaccurate, patients will not be served well. In contrast to the shared symptomatology across time, early conceptualizations of etiology and treatment choices differed dramatically from today, a genuine reflection of the times in which they were created. 相似文献

Cognitive change and enhanced coping: missing mediational links in cognitive behavior therapy with anxiety-disordered children 总被引:2,自引:0,他引:2
In this review, we examine the recent cognitive behavior therapy (CBT) outcome literature with anxiety-disordered children and, specifically, explore the status of cognitive change and increased coping ability as (1) specific treatment effects, and (2) possible mediators of the efficacy of CBT. In the past decade, the number of controlled CBT studies with clinically diagnosed anxiety-disordered children has increased substantially. CBT aims to restructure distorted or maladaptive cognitions and teach the anxious child to effectively use diverse coping strategies. Our review shows that in recent CBT research with anxiety-disordered children the use of domain-specific measures like cognitive and coping measures is, unfortunately, not common practice. Furthermore, only one study examined the issue of treatment mediation. Generally, recent CBT research has not been designed to test mediational issues and does not clarify whether cognitive change and enhanced coping—the presumed central components of CBT—are in fact responsible for its efficacy. Implications for the direction of future CBT research with anxiety-disordered children are discussed. 相似文献

Sources of individual differences in fraction skills 总被引:1,自引:0,他引:1
The purpose of this investigation was to evaluate a conceptual model of relations between two kinds of mathematical knowledge (simple arithmetic and conceptual knowledge), two kinds of child characteristics (working memory and on-task related classroom behavior), and individual differences in three kinds of fraction outcomes (fraction computation, estimation, and word problems) in 105 fifth grade students. Structural equation modeling provided consistent evidence that conceptual knowledge independently contributes to individual differences in the three fraction outcomes. Simple arithmetic knowledge was uniquely related only to variability in fraction computation skills. Mathematical knowledge was found to mediate some of the contributions of both working memory and classroom behavior on variability in fraction outcomes. These supported mediating processes extend the current literature by explication of the pathways via which characteristics of children may affect individual differences in fraction outcomes. 相似文献

The year of Thorndike's dissertation on animal intelligence, 1898, may mark the beginning of the field that eventually became known as the experimental analysis of behavior. The dissertation began a major shift in thinking about animal and human learning, provided important methodological innovations, and carried the seeds of later research and theory, particularly by B. F. Skinner. Although Thorndike was an associationist in 1898, the dissertation began the systematic search for fundamental behavioral processes, and laid the foundation for an empirical science of behavior. 相似文献

We examined how positive and negative reinforcement influenced time allocation, occurrence of problem behavior, and completion of parent instructions during a concurrent choice assessment with 2 preschool-aged children who displayed severe problem behavior in their homes. The children were given a series of concurrent choice options that varied availability of parent attention, access to preferred toys, and presentation of parent instructions. The results showed that both children consistently allocated their time to choice areas that included parent attention when no instructions were presented. When parent attention choice areas included the presentation of instructions, the children displayed differential patterns of behavior that appeared to be influenced by the presence or absence of preferred toys. The results extended previous applications of reinforcer assessment procedures by analyzing the relative influence of both positive and negative reinforcement within a concurrent-operants paradigm. 相似文献

Estimating multiple classification latent class models 总被引:4,自引:0,他引:4
E. Maris 《Psychometrika》1999,64(2):187-212
This paper presents a new class of models for persons-by-items data. The essential new feature of this class is the representation of the persons: every person is represented by its membership tomultiple latent classes, each of which belongs to onelatent classification. The models can be considered as a formalization of the hypothesis that the responses come about in a process that involves the application of a number ofmental operations. Two algorithms for maximum likelihood (ML) and maximum a posteriori (MAP) estimation are described. They both make use of the tractability of the complete data likelihood to maximize the observed data likelihood. Properties of the MAP estimators (i.e., uniqueness and goodness-of-recovery) and the existence of asymptotic standard errors were examined in a simulation study. Then, one of these models is applied to the responses to a set of fraction addition problems. Finally, the models are compared to some related models in the literature.Thanks are to Paul De Boeck for creating the intellectually stimulating atmosphere in which this class of models came about, Iven van Mechelen for theone-sided idea, Kikumi Tatsuoka for the use of her data, and Theodoor Bouw for running part of the simulation study. 相似文献

This study compared clock drawings by 42 medically hospitalized patients with a mean age of 51.9 (SD = 10.1) years, using four sets of published scoring criteria to determine comparability of classification and to assess validity by comparison to other measures of cognitive functioning. We found impairment in 20 of 42 cases using the criteria of Mendez et al. (1992); 11 of 42 cases by Sunderland et al. (1989); 9 of 42 cases with Freedman et al. (1994); and 8 of 42 cases according to Rouleau et al. (1992). Kappa coefficients of impairment status between sets of scoring criteria ranged from .41 to .86. Pearson correlations of raw scores between schemes ranged from .72 to .94. All except Sunderland et al. were significantly correlated with the Standardized Mini-Mental State Examination. All correlated significantly with the Wechsler Adult Intelligence Scale–Revised Block Design; however, only Mendez et al. correlated significantly with the Neurobehavioral Cognitive Status Examination. On the basis of these results and our experience, we recommend using the Freedman scoring scheme. 相似文献
