The Florida Department of Transportation used a series of changeable-message signs that functioned as freeway guide signs to divert traffic to Universal Theme Park via one of two eastbound exits based on traffic congestion at the first of the two exits. An examination of crashes along the entire route indicated a statistically significant increase in crashes at the first eastbound exit following the actuation of the system. Furthermore, all of the crashes occurred in close proximity to the exit gore (the crosshatched area at exits that drivers are not supposed to enter or traverse) at the first exit. In Experiment 1, behavioral data were collected using an alternating treatments design. These data revealed that reassigning the exit signs was effective in producing a change in the percentage of drivers using each of the two exits. These data also showed that the reassignment of the theme park exit was associated with an increase in the percentage of motor vehicle conflicts that consisted of vehicles cutting across the exit gore. An analysis revealed that the method used for switching the designated or active theme park exit on the series of changeable-message signs led to the presentation of conflicting messages to some motorists, thus resulting in erratic driving behavior (cutting across the exit gore). In Experiment 2, the treatment evaluated the use of a phased method of switching the designated theme park exit to eliminate the delivery of conflicting messages. The new method for switching the designated theme park exit was not associated with an increase in motorists cutting across the exit gore. 相似文献

本研究采用随机等组设计与铆测验相结合的方案。首先验证了两随机等组的平均数、方差和分布状态无显著差异,再用随机等组的等值分作为等值效标来检验其他等值方法的误差,然后比较了在铆测验设计中三种线性等值方法(在不同总体权重下)的误差值,以选出适合高中合考的等值方法及总体权重。经研究发现:会考等值宜采用Tucker观察分数线性等值方法,并宜选择总体权重W1=1。 相似文献

The association between children's externalizing behavior problems and mothers' overreactive discipline was examined in a longitudinally assessed sample of toddlers and their mothers. Path analyses indicated that mothers' overreactive discipline and children's externalizing behaviors were significantly and similarly stable over a 2 1/2-year period. No evidence of a cross-time influence of either variable on the other was observed. Mothers' overreactive discipline at Time 2 had a significant effect on Time 2 externalizing behavior. No significant effects of children's behavior on mothers' discipline were found. Mothers' depressive symptomatology and marital discord predicted initial overreactivity and were related to externalizing problems through their relations to overreactivity. The results support the appropriateness of implementing parenting interventions for externalizing problems before age 2 years. 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

Because single-subject design methodology is the cornerstone of behavior-analytic research, behavior analysts are often engaged in the practice of graph production. There are a variety of computer software packages on the market that can be used to create graphs; however, not all of them are suitable for producing single-subject design line graphs. Microsoft Excel 97 for Windows 95/NT and MacOS operating systems contains a variety of features that are conducive to producing reversal, multiple baseline, and multielement graphs (among others) that conform to many of the technical recommendations for publication in the Journal of Applied Behavior Analysis. We present detailed instructions on creating these graphs using Microsoft Excel. 相似文献

In this paper, I explore connections between two disciplines not typically linked: argumentation theory and urban design. I first trace historical ties between the art of reasoned discourse and the idea of civic virtue. I next analyze discourse norms implicit in three theories of urban design: Jane Jacobs' The Death and Life of Great American Cities (1961), Christopher Alexander's A Pattern Language: Towns, Buildings, Construction (1977), and Peter Katz's The New Urbanism: Toward an Architecture of Community (1994). I then propose a set of settlement issues of potential interest to both urban designers and argumentation theorists: size, density, heterogeneity, publicity, security, and identity. I conclude by suggesting that the good city be seen as both a spatial and a discursive entity. From such a perspective, good public discourse is dependent, at least in part, on good public space; and good public space is defined, at least in part, as a context conducive to good public discourse. 相似文献

This article reviews 21 studies which manipulated specific variables to determine their impact on the construct validity of assessment centers. This review shows that the studies regarding the impact of different observation, evaluation, and integration procedures yielded mixed results. Conversely, dimension factors (number, conceptual distinctiveness, and transparency), assessor factors (type of assessor and type of assessor training), and exercise factors (exercise form and use of role-players) were found to moderate construct validity. On the basis of the review, practical recommendations are derived to maximize the probability that practitioners design and administer an assessment center with construct validity. Finally, new perspectives for future research are identified. 相似文献

Replenishing item pools for on-line ability testing requires innovative and efficient data collection designs. By generating localD-optimal designs for selecting individual examinees, and consistently estimating item parameters in the presence of error in the design points, sequential procedures are efficient for on-line item calibration. The estimating error in the on-line ability values is accounted for with an item parameter estimate studied by Stefanski and Carroll. LocallyD-optimaln-point designs are derived using the branch-and-bound algorithm of Welch. In simulations, the overall sequential designs appear to be considerably more efficient than random seeding of items.This report was prepared under the Navy Manpower, Personnel, and Training R&D Program of the Office of the Chief of Naval Research under Contract N00014-87-0696.

Abstract. In this paper, I explore, as a Christian and a parish pastor, what drew me into the religion-science dialogue and what keeps me involved. Encounters with nature and readings of evolutionary theory answer some questions and raise others, especially questions about chance and the nature of God. I persist in my quest for understanding because creedal affirmations of God as Creator demand an examination of the relationship between God and the world, and because I want to proclaim the Christian message in a credible way to parishioners raised with a scientific worldview. Along the way I am reaping unexpected spiritual dividends. 相似文献

This essay examines the relation of Darwin's orchids book to a central persuasive flaw in theOrigin: Its inability to give variation sufficient presence to break the hold of design in the mind of the reader. Darwin characterized the orchids book as a flank movement on the enemy; this essay identifies the enemy as Paley's natural theology and the flank as thetopoi, maxims, and habits of perception that led Darwin's colleagues and contemporaries to see design in nature. Moreover, this essay examines three aspects of rhetorical timing pertinent toOrchids - time askairos, time as adequate duration, and time as transformation - and then relates those features to Robert Cox's Heideggerian logic of repetition, disavowal, and transcendence. The essay concludes with implications of the tactical and temporal aspects of Darwin's reasoning for understanding both the logic of science and of Darwin as a rhetorical artist.An earlier version of this essay appeared in the Proceedings of the Sixth SCA/AFA Conference on Argumentation. 相似文献
