We investigate the performance of three statistics, R 1, R 2 (Glas in Psychometrika 53:525–546, 1988), and M 2 (Maydeu-Olivares & Joe in J. Am. Stat. Assoc. 100:1009–1020, 2005, Psychometrika 71:713–732, 2006) to assess the overall fit of a one-parameter logistic model (1PL) estimated by (marginal) maximum likelihood (ML). R 1 and R 2 were specifically designed to target specific assumptions of Rasch models, whereas M 2 is a general purpose test statistic. We report asymptotic power rates under some interesting violations of model assumptions (different item discrimination, presence of guessing, and multidimensionality) as well as empirical rejection rates for correctly specified models and some misspecified models. All three statistics were found to be more powerful than Pearson’s X 2 against two- and three-parameter logistic alternatives (2PL and 3PL), and against multidimensional 1PL models. The results suggest that there is no clear advantage in using goodness-of-fit statistics specifically designed for Rasch-type models to test these models when marginal ML estimation is used.  相似文献

The present work constitutes an attempt to make explicit those pragmatic norms successfully operating in empirical science. I will first comment on the initial presuppositions of the discussion, in particular, on those concerning the instrumental character of scientific practice and the nature of scientific goals. Then I will depict the moderately naturalistic frame in which, from this approach, the pragmatic norms make sense. Third, I will focus on the specificity of the pragmatic norms, making special emphasis on what I regard as a key idea underlying them, namely, the view, vigorously advocated by classical pragmatists like C. S. Peirce and G. Vailati, that the best test for objectivity is the test of action. Finally, I am going to put forward a tentative list of pragmatic norms that can be abstracted from a careful observation and analysis of scientific practice as provided by current philosophers of experimentation (A. Franklin and F. Steinle among others). The norms will be divided into four classes corresponding to four aspects of science in which they rule, that is, self-correction, prediction, explanation and both experimentation and computation. In the following account, the formulation of those pragmatic norms successfully governing science will be understood as a contribution that scientifically-oriented pragmatism can make to the normative naturalistic project in epistemology.  相似文献

Observing a person in need usually provokes a compound and dynamic emotional experience made up of empathy and personal distress which, in turn, may influence helping behavior. As the exclusive use of rating scales to measure these two emotions does not permit the analysis of their concurrent evolution, we added the analogical emotional scale (AES) in order to measure how these two emotions evolve throughout the emotional experience, from its onset to its conclusion. Therefore, in two studies, the concurrence of empathy and personal distress was induced, both rating scales and AES were used, and participants were given an unexpected opportunity to help. Two effects were found. First, the helping behavior was lower when personal distress prevailed over empathy at the end of the experience (Studies 1 and 2). Second, this “end” effect was coherent with the nature of the different motives evoked by personal distress and empathy—directed to increasing either one’s own welfare (egoistic) or the victim’s welfare (altruism) (Study 2). These results support the usefulness of combining the rating scales and the AES for gaining a better understanding of the nature and behavioral consequences of complex, compound and dynamic emotional experiences.  相似文献

Friendship is a relationship that can traverse generations or be located within a specific era of a person's life. In this article, the author examines the role that her childhood friendship played in shaping her understanding of gender, ethnicity, poverty, immigration, spirituality and family processes. This friendship was during emerging adolescence and helped the author navigate and develop mestiza consciousness. These lessons were reinforced during her graduate training and have influenced her identity as a Chicana feminist therapist and the manner in which she connects with clients in psychotherapy. After presenting the story of her friendship, the author incorporates the theoretical perspectives of Chicana Feminism and Spirita to demonstrate how this friendship has influenced her clinical work with women. Specific themes discussed are language, invisibility, and cultural formulations of gender and spirituality.  相似文献

Cognitive complaints are common among subjects with fibromyalgia (FM). Yet, few studies have been able to document these deficits with cognitive tasks. A main limitation of existing studies is that attention has been broadly defined and the tasks used to measure attention are not designed to cover all the main components of the attentional system. Research on attention has identified three primary functions of attention, known as alerting, orienting and executive functioning. This study used the attentional network test-interactions task to explore whether and which of the three attentional networks are altered in FM. Results showed that FM patients have impaired executive control (greater interference), reduced vigilance (slower overall reaction time) and greater alertness (higher reduction in errors after a warning cue). Vigilance and alertness showed several relations with depression, anxiety and sleep quality. Sleep dysfunction was a significant predictor for alertness, whereas there were no significant predictors for vigilance. These findings highlight that the treatment of sleep difficulties in FM patients may help with some of their cognitive complaints.  相似文献

This cross-sectional study is part of EUROTEACH; a project aimed at examining the possible relationships between job conditions and wellness/ health outcomes in teachers from 11 European countries. The Spanish sample consists of 198 (53% female) teachers working in mixed public secondary schools in Alicante. The Job Demand-Control-Social Support (JDCS) model (Johnson and Hall, <citeref rid="bib18">1988</citeref>; Karasek and Theorell, <citeref rid="bib22">1990</citeref>) provides the theoretical framework for the study and specific instruments measuring additional job conditions and coping are applied to investigate these variables in the teaching profession. Moreover, the relationships between the variables are studied to clarify their possible interaction. Results confirm the expected relationship between job conditions and wellness/health effects, and also show the presence of an interaction between coping and the variables in the JDCS model. The need to perform further research on the role of coping, as well as considering other individual variables that might influence teacher occupational stress, is pointed out.  相似文献

Religious beliefs have had a key role in shaping local responses to HIV and AIDS. As the world's largest Catholic country, Brazil is no exception. Yet little research has been conducted to document how religious doctrine is enacted in practice among its lay leaders and followers. In this article, we present ethnographic research from Recife, Brazil, conducted to understand the way in which religious doctrines are interpreted at a local level. Contextualised within the sociology of contemporary Brazilian Catholicism, we draw on interviews with clergy members, lay leaders, and parishioners to discuss how the Catholic Church's vision of sexuality translates into everyday lives of its followers. We explore the disjuncture between the Catholic ideals of fidelity and delaying sex until marriage with the everyday reality of the Church's followers, highlighting the role that gender plays in defining sexual roles and expectations. We conclude by posing questions for future research and HIV prevention strategies considering the formal institutional response of the Brazilian Catholic Church to AIDS on the one hand, and the social and cultural contexts in which Catholics live their daily lives on the other.  相似文献

One barrier to widespread public access to empirically supported treatments (ESTs) is the limited availability and high cost of professionals trained to deliver them. Our earlier work from 2 clinical trials demonstrated that front-line addiction counselors could be trained to deliver a manualized, group-based cognitive behavioral therapy (GCBT) for depression, a prototypic example of an EST, with a high level of adherence and competence. This follow-up article provides specific recommendations for the selection and initial training of counselors, and for the structure and process of their ongoing clinical supervision. We highlight unique challenges in working with counselors unaccustomed to traditional clinical supervision. The recommendations are based on comprehensive feedback derived from clinician notes taken throughout the clinical trials, a focus group with counselors conducted 1 year following implementation, and interviews with key organization executives and administrators.  相似文献

We compared visual priming and comparison tasks to assess information processing of a stimulus during the first 2 s after its onset. In both tasks, a 13-ms prime was followed at varying SOAs by a 40-ms probe. In the priming task, observers identified the probe as rapidly and accurately as possible; in the comparison task, observers determined as rapidly and accurately as possible whether or not the probe and prime were identical. Priming effects attained a maximum at an SOA of 133 ms and then declined monotonically to zero by 700 ms, indicating reliance on relatively brief visuosensory (iconic) memory. In contrast, the comparison effects yielded a multiphasic function, showing a maximum at 0 ms followed by a minimum at 133 ms, followed in turn by a maximum at 240 ms and another minimum at 720 ms, and finally a third maximum at 1,200 ms before declining thereafter. The results indicate three stages of prime processing that we take to correspond to iconic visible persistence, iconic informational persistence, and visual working memory, with the first two used in the priming task and all three in the comparison task. These stages are related to stages presumed to underlie stimulus processing in other tasks, such as those giving rise to the attentional blink.  相似文献

The influence of religious education in the family upon current spiritual and religious tendencies was assessed in a sample of 599 Spanish nurse and medicine students using a religiosity scale and answers to a series of belief/disbelief statements. Results showed that nursing and medicine students were equally low-religious, with no differences in religiosity total scores between participants coming from religious families; however, medical students coming from nonreligious families showed higher religiousness than the corresponding nursing trainees. This distinction appeared both across religiosity items and in a variety of responses to belief/disbelief of Christian/secular assertions. Regression analysis showed that religious family background was a consistent predictor of religious beliefs at young adulthood, and its influence was higher for medical students. In addition to establish religious upbringing as an important factor modulating enduring religiosity, these findings provide distinctions between nurse and medical trainees, and reproduce, in a Spanish mainly catholic sample, the structure of religiosity factors previously found on North American mainline protestants.  相似文献
