The transformation of consequential functions in accordance with the relational frames of more-than and less-than

Across three experiments, the transformation of consequential functions in accordance with a seven-member relational network (A-B-C-D-E-F-G) was investigated. In this network, the relational rankings ranged from A, ranked the least, to G, ranked the most. In the first phase, contextual cues for more-than and less-than were established by training participants across multiple exemplars to select comparisons containing larger quantities in the presence of the former cue, and fewer quantities in the presence of the latter cue. Participants then were trained in six conditional discriminations (i.e., AD, F>E, and G>F) with the contextual cues as samples and nonsense words as comparisons, and all possible derived relations were tested (e.g., B相似文献   

Callous–Unemotional Traits in Predicting the Severity and Stability of Conduct Problems and Delinquency

The current study tests whether the presence of callous–unemotional (CU) traits designates a group of children with conduct problems who show an especially severe and chronic pattern of conduct problems and delinquency. Ninety-eight children who were selected from a large community screening of school children in grades 3, 4, 6 and 7 were followed across four yearly assessments. Children with conduct problems who also showed CU traits exhibited the highest rates of conduct problems, self-reported delinquency, and police contacts across the four years of the study. In fact, this group accounted for at least half of all of the police contacts reported in the sample across the last three waves of data collection. In contrast, children with conduct problems who did not show CU traits continued to show higher rates of conduct problems across the follow-up assessments compared to non-conduct problem children. However, they did not show higher rates of self-reported delinquency than non-conduct problem children. In fact, the second highest rate of self-reported delinquency in the sample was found for the group of children who were high on CU traits but without conduct problems at the start of the study.     

The role of secondary covariates when estimating latent trait population distributions

The U.S. National Assessment of Educational Progress (NAEP), the Third International Mathematics and Science Study (TIMSS), and the U.S. Adult Literacy Survey collect probability samples of students (or adults) who are administered brief examinations in subject areas such as mathematics and reading (cognitive variables), along with background demographic (primary) and educational environment (secondary) questions. The demographic questions are used in the primary reporting, while the numerous explanatory secondary variables, or covariates, are only directly utilized in subsequent secondary analyses. The covariates are also used indirectly to create the plausible values (multiple imputations) that are an integral part of analyses because of the use of sparse matrix sampling of cognitive items. The improvement in the precision of the primary reporting due to the inclusion of the covariates is assessed here and contrasted with the precision of reporting using plausible values created using only the primary demographic variables.The results demonstrate that the improvement in precision depends on the matrix sampling designs for the cognitive assessments. The improvements range from essentially none for the most common designs, to moderate for some less common designs. Consequently, two potential changes in the reporting procedures that could improve the statistical and operational efficiency of primary reporting are (a) eliminate or reduce the collection of covariates and increase the number of cognitive items, (b) to avoid delays, eliminate the covariates from the creation of plausible values used for the primary reports, but include them later when creating public-use files for secondary analyses. The potential improvements in statistical and operational efficiency must be weighed against the intrinsic interest in the covariates, and the potential for small discrepancies in the primary and secondary reporting.Thanks to Donald Rubin, Robert Mislevy, and John Barnard for their helpful comments and computing assistance.

Students Aggress Against Professors in Reaction to Receiving Poor Grades: An Effect Moderated by Student Narcissism and Self‐Esteem

Laboratory evidence about whether students’ evaluations of teaching (SETs) are valid is lacking. Results from three (3) independent studies strongly confirm that "professors" who were generous with their grades were rewarded for their favor with higher SETs, while professors who were frugal were punished with lower SETs (Study 1, d = 1.51; Study 2, d = 1.59; Study 3, partial η² = .26). This result was found even when the feedback was manipulated to be more or less insulting (Study 3). Consistent with laboratory findings on direct aggression, results also indicated that, when participants were given a poorer feedback, higher self‐esteem (Study 1 and Study 2) and higher narcissism (Study 1) were associated with them giving lower (more aggressive) evaluations of the "professor." Moreover, consistent with findings on self‐serving biases, participants higher in self‐esteem who were in the positive grade/feedback condition exhibited a self‐enhancing bias by giving their "professor" higher evaluations (Study 1 and Study 2). The aforementioned relationships were not moderated by the professor's sex or rank (teaching assistant vs.professor). Results provide evidence that (1) students do aggress against professors through poor teaching evaluations, (2) threatened egotism among individuals with high self‐esteem is associated with more aggression, especially when coupled with high narcissism, and (3) self‐enhancing biases are robust among those with high self‐esteem.

Predictors of early person reference development: Maternal language input,attachment and neurodevelopmental markers

In a longitudinal natural language development study in Germany, the acquisition of verbal symbols for present persons, absent persons, inanimate things and the mother–toddler dyad was investigated. Following the notion that verbal referent use is more developed in ostensive contexts, symbolic play situations were coded for verbal person reference by means of noun and pronoun use. Depending on attachment classifications at twelve months of age, effects of attachment classification and maternal language input were studied up to 36 months in four time points. Hierarchical regression analyses revealed that, except for mother absence, maternal verbal referent input rates at 17 and 36 months were stronger predictors for all referent types than any of the attachment organizations, or any other social or biological predictor variable. Attachment effects accounted for up to 9.8% of unique variance proportions in the person reference variables. Perinatal and familial measures predicted person references dependent on reference type. The results of this investigation indicate that mother-reference, self-reference and thing-reference develop in similar quantities measured from the 17-month time point, but are dependent of attachment quality.     

Developmentalism And The Child In Nineteenth-Century Science

In recent years, public science events have been designed as a means to foster a dialogue between science and the public and to contribute to ongoing policy processes. Regardless of their tangible outcome, such events rely on a certain framing, reconfigure scientific knowledge and conceptualise the public in specific ways. These constructs are exemplified by a science festival that was held in the train station hall in Zurich. Novel insights can be gained from a spatial, an object and an actor-related approach borrowed from the artistic context: the discussions about the White Cube can be adapted to contribute to the analysis of the science festival. When we look into the spatial situation created to foster exchange about scientific knowledge, we find how the exhibition display is taking care of minor details. While the organisers transformed the station hall into a laboratory, they created a kind of dialogic situation that filled an authority gap as it equally enabled exchange. The objects put in place in the exemplary case helped to design a customer–supplier relationship between the public and science. Under the umbrella of the science event, a range of diverse research endeavours was homogenised and unified. The audience, finally, was invited to familiarise itself with scientific knowledge. However, they were allocated a consumer role that obliged them to remain guests in the laboratory environment of the station hall. Thus, public science events may be successful in attracting large attendance and allowing more experiences with science, but while they create novel forms of familiarisation with science for visitors, they do not necessarily remedy public doubts about science and technology.     

Chaos and designing social systems

Growing appreciation of work done in the past several decades in complexity science is changing how we see the world. Efforts to apply what has been learned there to human systems such as organizations, perhaps through metaphor, challenges our views of social structures and how we may influence their organization and functioning. This article considers the implications of some key propositions from chaos theory for the design of social systems.     

Genetics,Faith, and Responsibility

The Battle of Dover is now concluded; and Charles Darwin's theory of evolution has won the legal day. The Theory of Evolution in the Darwainian and neo-Darwinian form is a very fertile theory; it generates hypotheses and research programs that lead to new knowledge. Even as a secular pursuit of knowledge, Christians appreciate science.

What the Christian community cannot tolerate is second-rate science; and it especially eschews pseudo-science. We ask for a general commitment; support the best science in our schools and laboratories as an expression of our Christian faith. In light of the public controversy regarding alternatives to teaching Darwinian science in our public schools, we offer six recommendations.     

Evolution by Natural Selection: Darwin's Gift to Science and Religion

The argument-from-design, based on biological evidence, was elaborated by William Paley in his Natural Theology (1802). It was revived in the 1990s by several authors, with a new moniker, the theory of intelligent design. In The Origin of Species (1859), Darwin advanced a scientific explanation of the design of organisms: evolution by natural selection. Organisms are pervaded by imperfections, dysfunctions, cruelties, and even sadism. The theory of evolution accounts for these mishaps, by natural selection, so that they need not be attributed to God's explicit design. The theory of evolution by natural selection is Darwin's gift to religion, in addition to its centrality in biology.
