In the present experiments, we examined the role of within-compound associations in the interaction of the overshadowing procedure
with conditioned stimulus (CS) duration, using a conditioned suppression procedure with rats. In Experiment 1, we found that,
with elemental reinforced training, conditioned suppression to the target stimulus decreased as CS duration increased (i.e.,
the CS duration effect), whereas, with compound reinforced training (i.e., the overshadowing procedure), conditioned suppression to the target stimulus
increased as CS duration increased. In subsequent experiments, we replicated these findings with sensory preconditioning and
demonstrated that extinction of the overshadowing stimulus results in retrospective revaluation with short CSs and in mediated
extinction with long CSs. These results highlight the role of the duration of the stimulus in behavioral control. Moreover,
these results illuminate one cause (the CS duration) of whether retrospective revaluation or mediated extinction will be observed. 相似文献

This article describes the development of a systematic and practical methodology for assessing program effectiveness and monitoring student development in undergraduate decision sciences programs. The model we present is based on a student's progression through learning stages associated with four key competencies: technical, analytical, communicative, and managerial. Key learning activities are embedded in major courses, resulting in clear and documented demonstrated abilities from the student. The work is based upon what is formally known about student outcomes assessment and input from our own Management Information Systems (MIS) program stakeholders and accrediting bodies. The results of the assurance of learning model can be, in turn, used to refine curriculum and to meet accreditation standards. 相似文献

The purpose of this study was to gain insight into the academic achievements of 200 talented athletes in 1992/1993 and 200 in 2006/2007, aged 14–16 years. When compared with the national average, the athletes in 2006/2007 attended pre‐university classes more often (χ2 = 57.001, p<.05). Of the 2006/2007 athletes, a higher percentage participated in pre‐university programs compared with that of athletes in 1992/1993 (χ2 (1, n = 400) = 32.003, p<.05), whereas the national averages showed stability (χ2 = .325, p>.05). Investigating self‐regulation appears relevant, as talented athletes may have developed a high sense of self‐regulation in sports, which may enable them to optimally profit from their self‐regulatory skills in their academics. 相似文献

Usability methods have received relatively little methodological attention within the field of E-Government. This paper aims to address this gap by reporting on a usability test of the municipal website of Deventer (the Netherlands), carried out by means of three variants of the think-aloud method (concurrent/retrospective think-aloud protocols and constructive interaction). These three methods had proved successful in a previous evaluation of a different municipal website, yet we decided to replicate our study in order to investigate whether the three methods would reveal different results when applied to another municipal website with a different information architecture. The results of our study showed that, as in the previous municipal website evaluation, the three evaluation methods were largely comparable in terms of output. Nevertheless, we did find a number of differences between the present and previous municipal website evaluation regarding the workings of the three methods—differences that could be explained by the different information architectures of the municipal websites tested. This suggests that the three evaluation methods might indeed work differently depending on the nature of the website that is being evaluated, and calls for more research into the effect of task type on the validity of evaluation methods. 相似文献

Variational principles play a central role in theoretical physics in many guises. We will discuss, in this instalment, some
curious features associated with a couple of variational problems. 相似文献

The fact that an accelerated charge radiates energy is considered an elementary textbook result in electromagnetism. Nevertheless,
this process of radiation (and its reaction on the charged particle) raises several conundrums about which technical papers
are written even today. In this installment, we will try to understand why an accelerated charge radiates in a simple, yet
rigorous, manner. 相似文献

We continue our exploration of random walks with some more curious results. We discuss the dimension dependence of some of
the features of the random walk, describe an unexpected connection between random walks and electrical networks and finally
discuss some remarkable features of random walk with geometrically decreasing step-length. 相似文献
