Examinee‐selected item (ESI) design, in which examinees are required to respond to a fixed number of items in a given set, always yields incomplete data (i.e., when only the selected items are answered, data are missing for the others) that are likely non‐ignorable in likelihood inference. Standard item response theory (IRT) models become infeasible when ESI data are missing not at random (MNAR). To solve this problem, the authors propose a two‐dimensional IRT model that posits one unidimensional IRT model for observed data and another for nominal selection patterns. The two latent variables are assumed to follow a bivariate normal distribution. In this study, the mirt freeware package was adopted to estimate parameters. The authors conduct an experiment to demonstrate that ESI data are often non‐ignorable and to determine how to apply the new model to the data collected. Two follow‐up simulation studies are conducted to assess the parameter recovery of the new model and the consequences for parameter estimation of ignoring MNAR data. The results of the two simulation studies indicate good parameter recovery of the new model and poor parameter recovery when non‐ignorable missing data were mistakenly treated as ignorable.  相似文献

Martin Luther's social writings (volumes 44–47 in the American edition) provide a robust account of human agency that might help Lutheran social ethics address contemporary crises of confidence. When Luther addresses concrete moral issues, he enriches his two‐kingdoms frame with a focus on particular social roles such as ruler, merchant, soldier, parent, etc. This (often tacit) “three‐estates” approach creates room for a distinctly Lutheran contribution to contemporary virtue theory by focusing on the functions served by particular social roles more than on individual self‐chosen pathways of moral improvement. It also supports a prophetic affirmation of vocation against the contemporary breakdown of expectations and confidence in social roles.  相似文献

The aim of this article is partly to analyze and discuss the ritual traditions in the Norwegian context, called disaster services, which consists in ritualizing as a response to accidents and disasters. Furthermore, we find it relevant to understand these traditions in relation to two aspects of recovery: personal and social recovery. From a practical theological perspective, the new traditions are interesting for the understanding of how the churches work in situations where people have stressful experiences, and for developing an understanding of contemporary religion.  相似文献

Peer Gynt, the main character in Ibsen's dramatic poem from 1867, has fascinated scholars since its publication. After a lifetime of escapades, Peer finds himself lonely, detached and with feelings of deadness. Gradually, the underlying structure of his personality confronts him. With the help of Wilfred Bion's ideas, it is possible to trace a distinct pattern, where unprocessed thoughts seem to play a decisive role in hindering Peer's self‐realization. The main female character, Solveig, spends her life waiting for Peer. Eventually she develops into a container, ready to welcome Peer's stray thoughts. This paper demonstrates how she evolves Bionian capacities like reverie, and eschewing of memory and desire. The interpretation that follows thus challenges a tradition where Solveig is seen as a romantic figure who, like Goethe's Gretchen, is designed to save the male protagonist by unconditional love. This paper argues that Solveig plays a more active role towards Peer in offering significant tools for personal development. The paper concludes that Ibsen and Bion have uncovered elements of basic human conditions that in some significant ways seem to coincide.  相似文献

Self‐determined learning is essential to academic success. The motivational resources development model argues that parents promote academic success in their children indirectly by nurturing self‐determined learner. In this study, applying a structural equation modelling and using data collected from 8th graders in Zhuhai, China (n = 1009) in 2012, we aim to answer 2 research questions: (a) What forms of parental involvement are highly correlated with self‐determined learning and (b) Can self‐determined learning fully mediate the relationship between parental involvement and students' academic performance? We find that parental leisure involvement is positively and significantly associated with the development of self‐determined learning, which in turn is significantly and positively correlated with academic achievement. Parental provision of structure or parental academic assistance is not significantly associated with students' self‐regulation and students' academic achievement.  相似文献

Noncontingent reinforcement (NCR) is typically implemented with extinction (EXT) for destructive behavior reinforced by social consequences and without EXT for destructive behavior reinforced by sensory consequences. Behavioral momentum theory (BMT) predicts that responding will be more persistent, and treatment relapse in the form of response resurgence more likely, when NCR is implemented without EXT due to the greater overall rate of reinforcement associated with this intervention. We used an analogue arrangement to test these predictions of BMT by comparing NCR implemented with and without EXT. For two of three participants, we observed more immediate reductions in responding during NCR without EXT. However, for all participants, NCR without EXT produced greater resurgence than NCR with EXT when we discontinued all reinforcers during an EXT Only phase, although there was variability in response patterns across and within participants. Implications for treatment of destructive behavior using NCR are discussed.  相似文献

Based on theoretical and empirical similarities between Construal level theory of psychological distance and the Need for cognitive closure (NFC) theory, it could be hypothesized that psychological distance and NFC represent constructs that overlap to some degree. Since both theories describe judgmental behavior in terms of schematic processing, we hypothesized that primacy effect, a schema-driven phenomenon, is strengthened under the heightened NFC and psychological distance. We tested this hypothesis in an impression formation experiment while manipulating psychological distance and measuring NFC. Low NFC and psychological closeness reflect preference for situationally specific, contextually rich information, and therefore their joint effect resulted in reliance on all available information regardless of their position in a sequence. High NFC and psychological distance produced a preference for clear, schematic, stable knowledge, and therefore weighed first information more, which resulted in the primacy effect.  相似文献

Responding to stimuli as same and different can be considered a critical component of a variety of language and academic repertoires. Whereas responding to “sameness” and generalized identity matching (i.e., coordination) have been studied extensively, there appears to be a significant gap in behavior analytic research and educational programs with regard to nonmatching relations or relations of difference. We review research on difference relations from a variety of domains, including comparative psychology, as well as experimental, and translational behavior analysis. We examine a range of studies, including research on the perception of difference and oddity responding, as well as investigations on establishing relational frames of distinction. We present suggestions for future research and describe potential methods for teaching skills related to relations of difference.  相似文献

We argue that the future of creativity research should focus on the dual goals of the development of individuals with great creative genius as well as the enhancement of creative activity in society in general. To achieve these goals, we need basic research that will help us better understand the fundamental nature of creativity. We describe an approach to creativity that emphasizes novelty over utility.  相似文献

The authors' purpose was to determine if participants adjusted their endpoint during a rapid aiming task in the context of changing rewards and whether participants needed consistent feedback to do so. Participants aimed to a target that was overlapped by a penalty region. Participants gained points for hitting the target but lost points for hitting the penalty region. The reward value associated with target contact either changed trial to trial, reducing consistent feedback (variable condition) or changed between blocks of trials (blocked condition) with the repetition of reward value within a block increasing the consistency of feedback. Participants adjusted their endpoints with changing reward value in the blocked but not variable condition indicating consistent feedback is needed to adjust endpoint to changing rewards.  相似文献
