There has been renewed interest in Barton and Lord’s (An upper asymptote for the three-parameter logistic item response model (Tech. Rep. No. 80-20). Educational Testing Service, 1981) four-parameter item response model. This paper presents a Bayesian formulation that extends Béguin and Glas (MCMC estimation and some model fit analysis of multidimensional IRT models. Psychometrika, 66 (4):541–561, 2001) and proposes a model for the four-parameter normal ogive (4PNO) model. Monte Carlo evidence is presented concerning the accuracy of parameter recovery. The simulation results support the use of less informative uniform priors for the lower and upper asymptotes, which is an advantage to prior research. Monte Carlo results provide some support for using the deviance information criterion and \(\chi ^{2}\) index to choose among models with two, three, and four parameters. The 4PNO is applied to 7491 adolescents’ responses to a bullying scale collected under the 2005–2006 Health Behavior in School-Aged Children study. The results support the value of the 4PNO to estimate lower and upper asymptotes in large-scale surveys. 相似文献

The new software package OpenMx 2.0 for structural equation and other statistical modeling is introduced and its features are described. OpenMx is evolving in a modular direction and now allows a mix-and-match computational approach that separates model expectations from fit functions and optimizers. Major backend architectural improvements include a move to swappable open-source optimizers such as the newly written CSOLNP. Entire new methodologies such as item factor analysis and state space modeling have been implemented. New model expectation functions including support for the expression of models in LISREL syntax and a simplified multigroup expectation function are available. Ease-of-use improvements include helper functions to standardize model parameters and compute their Jacobian-based standard errors, access to model components through standard R $ mechanisms, and improved tab completion from within the R Graphical User Interface. 相似文献

Researchers have shown that both differential reinforcement and response cost within token economies are similarly effective for changing the behavior of individuals in a group context (e.g., Donaldson, DeLeon, Fisher, & Kahng, 2014; Iwata & Bailey, 1974). In addition, these researchers have empirically evaluated preference for these procedures. However, few previous studies have evaluated the individual effects of these procedures both in group contexts and in the absence of peers. Therefore, we replicated and extended previous research by determining the individual effects and preferences of differential reinforcement and response cost under both group and individualized conditions. Results demonstrated that the procedures were equally effective for increasing on‐task behavior during group and individual instruction for most children, and preference varied across participants. In addition, results were consistent across participants who experienced the procedures in group and individualized settings. 相似文献

Despite their frequent use in the military and private sectors, the comparative effectiveness of colocated and distributed after-action reviews (AARs) is relatively unknown. Consequently, this study examined the comparative effectiveness of colocated and distributed AARs across taskwork and teamwork outcomes. Data were obtained from 492 participants randomly assigned to 123 four-person teams who participated in one of six AAR conditions. The results indicated that teams in the AAR conditions had significantly higher performance and team efficacy scores than the teams in the non-AAR conditions. In summary, the findings highlight that regardless of the training environment or type of AAR, the AAR remains an effective method at increasing performance and other outcomes. Therefore, the use of distributed AARs does not engender the posited process losses that were hypothesized. 相似文献

Adolescent mental health is a significant societal concern in the United States. Diagnosable mental health disorders have been reported at rates of 10–20 % among children and adolescents and this does not include adolescents experiencing personal and interpersonal distress not meeting diagnostic criteria. Adolescents who do not respond to traditional mental health services are often placed in residential treatment centers or other out-of-home treatment programs. Outdoor Behavioral Healthcare (OBH) is growing as a viable treatment option for adolescents who struggle with emotional, behavioral or substance related problems; however, questions have been raised about how to integrate the family into an OBH treatment setting. This article describes a case study illustrating how techniques from Narrative Family Therapy can be used to accomplish this integration, and offers a view of using Narrative Family Therapy to further involve families in the treatment and post-treatment process in an OBH program. 相似文献

In this paper I take up the question of whether Wilfrid Sellars has a notion of non‐conceptual perceptual content. The question is controversial, being one of the fault lines along which so‐called left and right Sellarsians diverge. In the paper I try to make clear what it is in Sellars' thought that leads interpreters to such disparate conclusions. My account depends on highlighting the importance of Sellars' little discussed thesis that perception involves a systematic form of mis‐categorization, one where perceivers mistake their sensory states to be properties of physical objects. I argue that the counterpart color and shape attributes of these states, which become ‘point of viewish’ when organized by the productive imagination, provides perceptual experience with its non‐conceptual representational content. I then argue that this content is not a form of the mythical Given because one can only have a non‐conceptual point of view on an object when an object is introduced into one's perceptual experience through the conceptual mis‐taking of one's sensory states. So, while Sellars has a notion of non‐conceptual representational content, it can only be salient in the context of a perceptual act that is conceptual overall. 相似文献
