We present an interface connecting the ACL2 theorem prover with external deduction tools. The ACL2 logic contains several mechanisms for proof structuring, which are important to the construction of industrial-scale proofs. The complexity induced by these mechanisms makes the design of the interface challenging. We discuss some of the challenges, and develop a precise specification of the requirements on the external tools for a sound connection with ACL2. We also develop constructs within ACL2 to enable the developers of external tools to satisfy our specifications. The interface is available with the ACL2 theorem prover starting from Version 3.2, and we describe several applications of the interface. 相似文献

Abstract : This article addresses the large issue that looms in any Christian engagement with a different faith: the confession of Christ as incarnate God. The manner in which this issue is addressed is by focusing on the difference between Islamic and classical Lutheran understandings of sin. I shall attempt to present the Islamic understanding of sin and articulate how the Islamic understanding of Christ is shaped by its hamartiology. I shall conclude with a few practical suggestions for dialoguing with Muslims on the issue of sin. 相似文献

Whilst the Triple P Positive Parenting Program has a large evidence base (Sanders, Clinical Child and Family Psychology Review
2:71–90, 1999; Sanders, Journal of Consulting and Clinical Psychology 68:624–640, 2000) and preliminary evidence indicates that Stepping Stones Triple P is also efficacious (Roberts, Journal of Clinical Child
and Adolescent Psychology, 35(2):180–193, 2006), to date Stepping Stones has not been evaluated with the ASD population. Fifty-nine families with a child with ASD aged
between 2 and 9 participated in this randomized controlled trial. The results demonstrate significant improvements in parental
reports of child behaviour and parenting styles with the treatment effects for child behaviour, parental over reactivity and
parental verbosity being maintained at follow-up 6 months later. Further, the results suggest significant improvements in
parental satisfaction and conflict about parenting as well as a sleeper effect for parental efficacy. The results indicate
that Stepping Stones Triple P is a promising intervention for parents of children with ASD. Limitations and future research
are also addressed. 相似文献

Computer-simulated microworlds can provide a controlled method for investigating concepts related to naturalistic decision making (NDM). However, the extent to which these tools can be used to generate meaningful outcomes is unknown. The current study used a microworld called Networked Fire Chief (NFC) to explore the range of skills and knowledge acquired as participants gained practice on the program. The complexity of the NFC NDM environment was also explored. Twenty participants each completed 20 equivalent 5-min scenarios on NFC. Interview data, behavioral data and performance scores were collected across the trials. Results confirmed that NFC provides an environment that promotes appropriate perceptual-cognitive processing for NDM. However, performance improved to only a small extent across the 20 trials in four performance areas: speed, accuracy, efficiency and planning. In addition, the number of personal and situational factors to be considered when decision making on NFC was not comparable with real-world NDM environments. Overall, results indicated that the use of microworlds for research should be regulated by an understanding of the limitations of their applicability. 相似文献

This report describes the 3 year outcomes of three different variants of the Triple P-Positive Parenting Program, a behavioural
family intervention. Families were randomly assigned to one of three intervention conditions or to a waitlist condition. At
1 year follow-up there were similar improvements on observational and self-report measures of preschooler disruptive behaviour
for Enhanced, Standard and Self Directed variants of Triple P. At 3 year follow-up (completed by 139 families), each condition
showed a similar level of maintenance of intervention effects. Approximately 2/3 of preschoolers who were clinically elevated
on measures of disruptive behaviour at pre-intervention moved from the clinical to the non-clinical range. Across conditions,
there was a comparable preventive effect for each intervention for these high risk children. The implications of the findings
for the development of brief, cost effective parenting interventions within a public health framework are discussed. 相似文献

Few genetically-informative studies have attempted to explicitly identify the shared environmental (i.e., those environmental influences that contribute to sibling similarity) factors now known to contribute to adolescent delinquency. The current study therefore examined whether the parent-child relationship served as one source of these shared environmental influences. Participants were 610 adoptive and biological families from the Sibling Interaction and Behavior Study (SIBS). Parents and adolescents reported on their parent-child conflict and parental involvement with child, and adolescents reported on their own delinquent behaviors. We employed structural equation modeling and supplementary multilevel modeling, finding consistent evidence that the association between delinquency and the parent-child relationship is at least partially shared environmental in origin. Such findings provide an important extension of previous twin studies, as they suggest that passive genotype-environment correlations do not explain earlier findings of shared environmental influences on this association. 相似文献

Eighty-nine high school seniors were administered a questionnaire that gathered information on their exercise habits (ranging from rarely to daily), relationships with parents and peers, depressive tendencies, sports involvement, drug use, and academic performance. Students with a high level of exercise had better relationships with their parents (including greater intimacy and more frequent touching), were less depressed, spent more time involved in sports, used drugs less frequently, and had higher grade point averages than did students with a low level of exercise. 相似文献

Regional cerebral glucose metabolism in aphemia: A case report 总被引:1,自引:0,他引:1

Local cerebral metabolism was determined in a patient suffering aphemia following cerebral infarction using the 18FDG-PET technique. The syndrome was characterized by profound ictal nonfluency with sparing of other language functions. Speech subsequently improved so that content and grammar were appropriate but mild dysprosody persisted. Conventional CT showed no lesion of the left hemisphere while PET revealed a discrete focus of hypometabolism on the left which partially resolved on serial studies. The metabolic lesion could be localized to the region of the inferior precentral gyrus and the adjacent subcortical space. 相似文献

The current study investigates two recently identified threats to the construct validity of behavioral inhibition as a core
deficit of attention-deficit/hyperactivity disorder (ADHD) based on the stop-signal task: calculation of mean reaction time
from go-trials presented adjacent to intermittent stop-trials, and non-reporting of the stop-signal delay metric. Children
with ADHD (n = 12) and typically developing (TD) children (n = 11) were administered the standard stop-signal task and three variant stop-signal conditions. These included a no-tone
condition administered without the presentation of an auditory tone; an ignore-tone condition that presented a neutral (i.e.,
not associated with stopping) auditory tone; and a second ignore-tone condition that presented a neutral auditory tone after
the tone had been previously paired with stopping. Children with ADHD exhibited significantly slower and more variable reaction
times to go-stimuli, and slower stop-signal reaction times relative to TD controls. Stop-signal delay was not significantly
different between groups, and both groups’ go-trial reaction times slowed following meaningful tones. Collectively, these
findings corroborate recent meta-analyses and indicate that previous findings of stop-signal performance deficits in ADHD
reflect slower and more variable responding to visually presented stimuli and concurrent processing of a second stimulus,
rather than deficits of motor behavioral inhibition. 相似文献
