In the social, behavioral, and health researches it is a common strategy to collect data along time on more than one group of participants on multiple dependent variables. To analyse this kind of data is very complicated due to the correlations between the measures taken in different points of the time, and between the answers. Usually to analyse these data the multivariate mixed model, or the doubly multivariate model, are the most frequent approaches. Both of them require combined multivariate normality, equal covariance matrices, independence between the observations of different participants, complete measurements on all subjects, and time-independent covariates. When one ore more of these assumptions are not accomplished these approaches do not control in the correct way the Type I error, and this affects the validity and the accuracy of the inferences. In this paper some solutions that solve the problems with the error Type I will be shown. Several programs for a correct realization of the analyses through the SAS Proc Mixed procedure are presented.  相似文献

Numerous studies show that personal spirituality developed through prayer positively influences mental health. Phenomenological and neuroscientific studies of mindfulness, an Eastern meditative prayer form, reveal significant health benefits now yielding important insights useful for guiding treatment of psychological disorders. By contrast, and despite its practice for millennia, Christian meditation is largely unrepresented in studies of clinical efficacy. Resemblances between mindfulness and disciplinary acts in Christian meditation taken from the ancient Greek practice of askesis suggest that Christian meditation will prove similarly beneficial; furthermore, psychological and neuroscientific studies suggest that its retention of a dialogical and transcendent praxis will additionally benefit social and existential psychotherapy. This paper thus argues that study of contemplative meditation for its therapeutic potential is warranted.  相似文献

The concept of polarity is pervasive in natural language. It relates syntax, semantics and pragmatics narrowly (Giannakidou, in: Maienborn, von Heusinger, Portner (eds.), Semantics: an international handbook of natural language meaning, De Gruyter Mouton, Berlin, 2011; Israel in The grammar of polarity: pragmatics, sensitivity, and the logic of scales, Cambridge studies in linguistics, Cambridge University Press, Cambridge, 2014), it refers to items of many syntactic categories such as nouns, verbs and adverbs. Neutral polarity items appear in affirmative and negative sentences, negative polarity items cannot appear in affirmative sentences, and positive polarity items cannot appear in negative sentences. A way of reasoning in Natural Language is through Natural Logic (van Benthem in Essays in logical semantics, vol. 29 of Studies in linguistics and philosophy, Reidel, Dordrecht, 1986; Language in action: categories, lambdas, and dynamic logic, vol. 130 of Studies in logic, Elsevier, Amsterdam, 1991). This logic is based on the concept of polarity in order to make the meaning of a sentence weaker o stronger without changing its truth value. There exist many proposals to compute polarity in the Natural Logic context, the most widely known are the ones by: van Benthem (1986, 1991), Sánchez-Valencia (Studies on natural logic and categorial grammar, Ph.D. thesis, Universiteit van Amsterdam, 1991), Dowty (Proceedings of the 4th conference on semantics and theoretical linguistics, Cornel University, CLC Publications, Rochester, 1994), and van Eijck (in: ten Cate, Zeevat (eds.), 6th international Tbilisi symposium on logic, language, and computation, Batumi, Georgia, Springer, 2007). If Natural Logic is going to be used, as an inferential mechanism between text fragments, in Natural Language Processing applications such as text summarization, question answering, and information extraction, it is a priority to know what the existing relationship among the aforementioned algorithms is; for example, to implement the most general. We show in this paper the equivalence among the analyzed algorithms, filling a gap in Natural Logic research, particularly in computing polarity, and the soundness of their algorithms.  相似文献

This article analyses the dissemination of conspiracy theories in late 20th-century Argentina, particularly those connected with the idea of Synarchy, a supposed underground global network working against the country’s interests. It reconstructs the projection and impact of those theories among Peronist right-wing and left-wing followers as well as among anti-Peronist intellectuals. While not necessarily anti-Semitic, the suspicion of such a network plotting in the shadows affected the public imaginary of society, spilling at certain points into explicit anti-Semitism. The text also addresses the long-term effect of a connected myth, the Plan Andinia, a plot supposedly articulated by Jews and/or young Israelis who, while touring Patagonia, were thought to be undercover agents preparing a territorial takeover of the southern region to create a second Jewish state. Analysis reveals that even in the early twenty-first century such conspirationist logic continued to pervade some of Argentina’s high echelons of power.  相似文献

We tested how anticipated emotions interact with personal experience in risk behavior to improve predictions from TPB on behavioral intention (BI) and behavioral expectation (BE) for sex without condom (Study 1) and excessive drinking (Study 2). In the moderate-high experience group, anticipated emotional profiles (AEPs) improve TPB prediction from 28% to 45% in the case of BI and from 19% to 40% in that of BE in relation to sexual risk behavior (Study 1), and from 23% to 36% in the case of BI and from 17% to 31% in that of BE in relation to binge drinking (Study 2). However, in the low-experience group (Study 2) AEPs improve TPB predictions for BI (12% to 34%) but not for BE, showing that in less experienced people BI and BE are not equivalent: anticipated emotions have different relevance in their prediction. These results were replicated using a general negative anticipated emotion index (averaging emotional categories).  相似文献

In recent years there has been an increasing interest among researchers and practitioners to analyze what makes a firm attractive in the eyes of university students, and if individual differences such as personality traits have an impact on this general affect towards a particular organization. The main goal of the present research is to demonstrate that a recently conceptualized narrow trait of personality named dispositional resistance to change (RTC), that is, the inherent tendency of individuals to avoid and oppose changes (Oreg, 2003), can predict organizational attraction of university students to firms that are perceived as innovative or conservative. Three complementary studies were carried out using a total sample of 443 college students from Mexico. In addition to validating the hypotheses, our findings suggest that as the formation of the images of organizations in students' minds is done through social cognitions, simple stimuli such as physical artifacts, when used in an isolated manner, do not have a significant impact on organizational attraction.  相似文献

Occupying gender stereotype-incongruent roles can lead individuals to lose status and earn a lower salary. The present research examined whether merely working for a supervisor in a gender-atypical occupational role leads a subordinate to lose status. Two studies found that male subordinates of gender deviants (i.e., a female supervisor in a masculine domain or a male supervisor in a feminine domain) were accorded lower status and were paid less than male subordinates of supervisors in gender-congruent roles (i.e., a female supervisor in a feminine domain or a male supervisor in a masculine domain). However, the status of female subordinates was unaffected by working for a gender atypical supervisor. Moreover, the status loss for male subordinates was mediated by a perceived lack of masculinity. Thus, establishing the male subordinate's masculine credentials eliminated the bias.  相似文献

Although, in everyday life, patients with attention deficit hyperactivity disorder (ADHD) are frequently distracted by goal-irrelevant affective stimuli, little is known about the neural and behavioral substrates underlying this emotional distractibility. Because some of the most important brain responses associated with the sudden onset of an emotional distracter are characterized by their early latency onset and short duration, we addressed this issue by using a temporally agile neural signal capable of detecting and distinguishing them. Specifically, scalp event-related potentials (ERPs) were recorded while 20 boys with ADHD combined type and 20 healthy comparison subjects performed a digit categorization task during the presentation of three types of irrelevant, distracting stimuli: arousing negative (A−), neutral (N) and arousing positive (A+). Behavioral data showed that emotional distracters (both A− and A+) were associated with longer reaction times than neutral ones in the ADHD group, whereas no differences were found in the control group. ERP data revealed that, compared with control subjects, boys with ADHD showed larger anterior N2 amplitudes for emotional than for neutral distracters. Furthermore, regression analyses between ERP data and subjects’ emotional ratings of distracting stimuli showed that only in the ADHD group, emotional arousal (ranging from calming to arousing) was associated with anterior N2: its amplitude increased as the arousal content of the visual distracter increased. These results suggest that boys with ADHD are more vulnerable to the distracting effects of irrelevant emotional stimuli than control subjects. The present study provides first data on the neural substrates underlying emotional distractibility in ADHD.  相似文献
