There is a frequent need to measure the degree of agreement among R observers who independently classify n subjects within K nominal or ordinal categories. The most popular methods are usually kappa-type measurements. When R = 2, Cohen's kappa coefficient (weighted or not) is well known. When defined in the ordinal case while assuming quadratic weights, Cohen's kappa has the advantage of coinciding with the intraclass and concordance correlation coefficients. When R > 2, there are more discrepancies because the definition of the kappa coefficient depends on how the phrase ‘an agreement has occurred’ is interpreted. In this paper, Hubert's interpretation, that ‘an agreement occurs if and only if all raters agree on the categorization of an object’, is used, which leads to Hubert's (nominal) and Schuster and Smith's (ordinal) kappa coefficients. Formulae for the large-sample variances for the estimators of all these coefficients are given, allowing the latter to illustrate the different ways of carrying out inference and, with the use of simulation, to select the optimal procedure. In addition, it is shown that Schuster and Smith's kappa coefficient coincides with the intraclass and concordance correlation coefficients if the first coefficient is also defined assuming quadratic weights. 相似文献

Causal illusion has been proposed as a cognitive mediator of pseudoscientific beliefs. However, previous studies have only tested the association between this cognitive bias and a closely related but different type of unwarranted beliefs, those related to superstition and paranormal phenomena. Participants (n = 225) responded to a novel questionnaire of pseudoscientific beliefs designed for this study. They also completed a contingency learning task in which a possible cause, infusion intake, and a desired effect, headache remission, were actually non-contingent. Volunteers with higher scores on the questionnaire also presented stronger causal illusion effects. These results support the hypothesis that causal illusions might play a fundamental role in the endorsement of pseudoscientific beliefs. 相似文献

This article focuses on the third volume of Vel-Matti Kärkkäinen's systematic theology, titled Creation and Humanity. After a brief overview of the volume the article offers some clarification on the tenth chapter, especially on its interaction with paleontology. After that, two constructive observations follow. The first is related to Kärkkäinen's notion of the embeddedness of human nature, and the second is to further employ systems thinking in his constructive work on creation and human evolution. 相似文献

The current study examined unfolding relations among mothers’ mindful parenting, parent–adolescent recurrent conflict, and adolescents’ externalizing and internalizing problems. In a community sample of 117 families (31% black, Asian, American Indian, or Latino), parents and adolescents (52% female; average age = 12.13 years) were followed over 15 months. Parents answered questions about mindful parenting and recurrent conflict, and adolescents reported on their own externalizing and internalizing problems. Path analyses indicated that higher levels of mindful parenting were significantly related to lower levels of recurrent conflict 2–3 months later, controlling for previous levels of recurrent conflict. Moreover, lower levels of recurrent conflict were significantly related to lower levels of externalizing problems and internalizing problems 1 year later, controlling for previous levels of those problems. Subgroup analyses indicated that relations were comparable across subgroups defined by adolescent gender, race, parent marital status, and family financial strain. The effects of mindful parenting were robust even after accounting for other indicators of positive and supportive parenting, namely inductive reasoning and warmth in the parent–adolescent relationship. These findings highlight the potential of mindful parenting to improve family interactions and adolescent adjustment. 相似文献

A recent re-operationalisation of grandiose narcissism has resulted in the distinction of two narcissistic strategies based on the cognitive, affective-motivational and behavioural dynamics: admiration (assertive self-enhancement) and rivalry (antagonistic self-protection). The Narcissistic Admiration and Rivalry Questionnaire (NARQ) was developed to assess this model with two higher-order dimensions. However, cross-validations of the NARQ have not been extensively conducted across diverse population groups and languages. This study aimed to test the internal and external validity (through the relation with envy and self-esteem), reliability and cross-cultural equivalence of the Spanish version of the NARQ. The psychometric properties were evaluated in a Spanish sample (N = 310), and cross-cultural equivalence was tested in participants from Chile (N = 234) and Colombia (N = 256). The results supported the reliability and validity of the Spanish NARQ, as well as the cross-cultural equivalence across Spanish-speaking countries. In addition, we discuss obtained differences across Spanish, Chilean and Colombian sample within two narcissistic strategies. 相似文献

Using data from a longitudinal study, the present study employed a latent class mover-stayer analytical strategy to examine both the cross-sectional and longitudinal (+33 months) relationship between membership of stress classes, and subjective life expectancy. Participants were from 21 High schools in Scotland and Northern Ireland. Data were collected in the first year of High school (mean age = 12.5 years), and at +33 months (fourth year, or school year 11). Sample 1 consisted of 1171 adolescents (40.82% females, 2.56% unreported) in Northern Ireland. Sample 2 consisted of 1059 adolescents (52.79% females, 1.32% unreported) in Scotland. Adolescents with the lowest levels of stress projected the highest subjective life expectancy scores. Longitudinal analyses were jumbled and not in keeping with cross-sectional results. More research may be needed on the trajectory of subjective life expectancy over time before it can be depended upon as a reliable outcome variable in adolescent development. 相似文献

Founded and led by a U.S.-born white pastor, Amor Poderoso is a nondenominational, evangelical megachurch in El Paso, Texas, almost entirely composed of Mexican-Americans, recent Mexican immigrants, and current Mexican citizens. Ethnographic fieldwork from 2014 to 2017, supplemented with interviews with pastors, worship leaders, and attendees, reveal that much of congregational life orients around intentionally showcasing “Mexican” culture through sounds, images, and artifacts that appropriate an array of idealized ethnic references (e.g., food, dress, mannerisms, clichés) from Northern Mexico. Ongoing ethnic displays do not originate spontaneously or impromptu from membership but rather serve as a form of tactical authenticity derived from U.S. racial schemas mobilized by congregational leaders as a distinctive religious resource. Weekly worship services featuring dialect-inflected Spanish preaching and singing project ethnic signals that elicit connections to both a common ancestral heritage and a common religious identity. In short, church leaders at this southern border Latino church deliberately deploy sounds, images, and artifacts to assert racialized performances of being “Mexican” for distinctly religious purposes, especially evangelization. In the process, the distinctive practices of religious racialization effectively structure church members’ ethnic and religious identities around racial tropes to buttress a cogent corporate identity for enacting institutionalized evangelical narratives and legitimating charismatic authority. 相似文献

Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study. 相似文献

Deficits in response to name (RTN) are an early indicator of autism spectrum disorder (ASD), and RTN is a treatment goal in many early intervention curricula for children with ASD. However, little research has empirically evaluated methods for increasing RTN in children with ASD. We evaluated a series of conditions designed to increase RTN for 4 children with ASD using a multielement experimental design. The schedules of tangible reinforcement were thinned after mastery and generalization was tested across people and contexts. Tangible reinforcers were necessary to increase RTN for all 4 participants, and the schedule of reinforcement was successfully thinned with all participants after intervention. Generalization was also observed across people and experimental contexts. 相似文献
