Rasch analysis was used to illustrate the usefulness of item-level analyses for evaluating a common therapy outcome measure of general clinical distress, the Symptom Checklist-90-Revised (SCL-90-R; Derogatis, 1994). Using complementary therapy research samples, the instrument's 5-point rating scale was found to exceed clients' ability to make reliable discriminations and could be improved by collapsing it into a 3-point version (combining scale points 1 with 2 and 3 with 4). This revision, in addition to removing 3 misfitting items, increased person separation from 4.90 to 5.07 and item separation from 7.76 to 8.52 (resulting in alphas of .96 and .99, respectively). Some SCL-90-R subscales had low internal consistency reliabilities; SCL-90-R items can be used to define one factor of general clinical distress that is generally stable across both samples, with two small residual factors. 相似文献

Abstract This study examines whether states follow the religion policies they declare in their constitutions. It identifies four types of policies which officially seek to limit religion's role in government: absolute separation of religion and state (SRAS); neutral political concern; exclusion of ideals; and secularism–laicism. I determine whether states follow these policies using the religion and state (RAS) dataset and compare this to constitutional declarations that the state is secular and declarations of separation of religion and state. The results show that a majority of states which make both types of declaration do not follow these policies based on any of the four standards used in this study. However, the presence and wording of these clauses are correlated with state religion policy. 相似文献

Methodological and empirical issues in research on action information feedback (AIF) are discussed, with particular reference to the procedures and results of Annett (1970). Positioning responses practiced under conditions of AIF training are learned, though generally less well than under terminal IF conditions. Effects obtained as a result of AIF training may be subject to variations in movement extent required, gain and other transformations, frequency, temporal locus, and mode of augmentation, many aspects of which remain to be systematically studied. 相似文献

ABSTRACTThe rhetoric, rumor, and hostility that surrounded the election of Barack Obama in 2008 appeared to correspond with the notion of a “moral panic.” However, systematically measuring phenomena like moral panics, which are volatile and dispersed in nature, can be difficult. This paper utilizes Google search data combined with other sources to examine the reaction to the candidacy and initial election of Obama. Given the nature of this particular panic, we hypothesize that panic-induced searches will be greater in states with a larger presence of Evangelical Protestants and consumption of conservative media outlets. Results from a series of generalized least squares time-series and two-stage regression models demonstrate that searches related to “socialism” and the “Antichrist” grew significantly around Obama’s election, indicating Obama’s “folk devil” status and a growing moral panic. Additionally, the intensity of the panic appears to be moderated by religious cultures and media consumption. Implications for theory and future research are discussed. 相似文献

Machine ethics and robot rights are quickly becoming hot topics in artificial intelligence and robotics communities. We will argue that attempts to attribute moral agency and assign rights to all intelligent machines are misguided, whether applied to infrahuman or superhuman AIs, as are proposals to limit the negative effects of AIs by constraining their behavior. As an alternative, we propose a new science of safety engineering for intelligent artificial agents based on maximizing for what humans value. In particular, we challenge the scientific community to develop intelligent systems that have human-friendly values that they provably retain, even under recursive self-improvement. 相似文献

The purpose of this study was to examine developmental change and the influence of shyness on social problem-solving (SPS). At 24, 36, and 48 months, children (N = 570) were observed while interacting with an unfamiliar peer during an SPS task and at 24 months, maternal report of shyness was collected. Results showed that across the full sample, children displayed low but stable levels of withdrawn SPS and increasing levels of SPS competence over development. In addition, results showed multiple trajectories of withdrawn and competent SPS. Shyness was associated with high-increasing and high-decreasing withdrawn SPS trajectories compared with the low-increasing withdrawn SPS trajectory. Shyness was also associated with the low-increasing compared with the high-increasing SPS competence trajectory. Findings demonstrate the development of SPS competence over early childhood, and the influence of early shyness on this developmental course, with some shy children showing improvement in SPS skills and others continuing to show SPS difficulties over time. 相似文献

Clusterwise linear regression is a multivariate statistical procedure that attempts to cluster objects with the objective of minimizing the sum of the error sums of squares for the within-cluster regression models. In this article, we show that the minimization of this criterion makes no effort to distinguish the error explained by the within-cluster regression models from the error explained by the clustering process. In some cases, most of the variation in the response variable is explained by clustering the objects, with little additional benefit provided by the within-cluster regression models. Accordingly, there is tremendous potential for overfitting with clusterwise regression, which is demonstrated with numerical examples and simulation experiments. To guard against the misuse of clusterwise regression, we recommend a benchmarking procedure that compares the results for the observed empirical data with those obtained across a set of random permutations of the response measures. We also demonstrate the potential for overfitting via an empirical application related to the prediction of reflective judgment using high school and college performance measures. 相似文献

The paucity of mental health studies with Orthodox Jews makes culturally competent counseling care unlikely. In this large‐scale investigation of marriage among Orthodox Jews, most respondents reported satisfaction with marriage and spouse, although satisfaction was highest among recently married couples. The most significant stressors were finances, communication, physical intimacy/sexuality, time pressures, and in‐law conflicts. Counseling interventions are discussed. La escasez de estudios sobre salud mental en poblaciones de judíos ortodoxos limita la posibilidad de ofrecer un cuidado de consejería culturalmente competente. En esta investigación a gran escala sobre el matrimonio entre judíos ortodoxos, la mayoría de los participantes indicaron satisfacción con su matrimonio y esposo/a, aunque la satisfacción fue mayor entre las parejas recién casadas. Los elementos estresantes más significativos fueron las finanzas, la comunicación, el contacto íntimo/sexualidad, la falta de tiempo, y los conflictos con la familia política. Se discuten intervenciones para la consejería. 相似文献

ABSTRACT Few studies have examined the impact of age on reactivity to concurrent think-aloud (TA) verbal reports. An initial study with 30 younger and 31 older adults revealed that thinking aloud improves older adult performance on a short form of the Raven's Matrices (Bors & Stokes, 1998, Educational and Psychological Measurement, 58, p. 382) but did not affect other tasks. In the replication experiment, 30 older adults (mean age = 73.0) performed the Raven's Matrices and three other tasks to replicate and extend the findings of the initial study. Once again older adults performed significantly better only on the Raven's Matrices while thinking aloud. Performance gains on this task were substantial (d = 0.73 and 0.92 in Experiments 1 and 2, respectively), corresponding to a fluid intelligence increase of nearly one standard deviation. 相似文献
