In this paper we show that the quasivariety generated by an infinite simple MV-algebra only depends on the rationals which it contains. We extend this property to arbitrary families of simple MV-algebras. 相似文献

A 10-year naturalistic study of 313 patients who entered treatment for unipolar depression and a community comparison group of 284 nondepressed adults was conducted. We compared life stressors, social resources, personal resources, and coping among patients who were remitted (N = 76), partially remitted (N = 146), or nonremitted (N = 91). Compared with the controls and the remitted patients, the partially remitted and nonremitted patients consistently experienced more life stressors and fewer social resources, were less easygoing, and relied more on avoidance coping. A less easygoing disposition, fewer close relationships, and more reliance on avoidance coping were associated with higher odds of experiencing a course of partial remission or nonremission. In addition, more depressive symptoms and medical conditions predicted nonremission. 相似文献

Twenty-six children with attention deficit/hyperactivity disorder (ADHD) participated in a double-blind trial consisting of 2 consecutive weeks each of placebo and methylphenidate (M = 26.92 mg/day = 0.78 mg/kg/day). As expected, stimulant therapy resulted in moderate weight loss, increased somatic complaints, and teacher and parent reports of reduced inattentiveness, aggression, and oppositionality. In both phases of the trial, patients were tested in a choice reaction time task assessing two aspects of the task that presumably affect response selection: response frequency (ratio of targets/nontargets = 25/75 vs. 50/50) and stimulus sequence (alternations vs. repetitions). Both manipulations yielded expected results on performance and event-related potentials (ERPs). Stimulant treatment increased accuracy and speed among younger children and curtailed variability of reaction time for the sample as a whole. However, methylphenidate did not affect ERPs. In combination, the results imply that the enhancement of performance by methylphenidate does not involve the demands of response selection examined in this study. 相似文献

Examined the role of socioecological factors (family functioning and socioeconomic variables) in predicting behavioral and cognitive adaptation in children with sickle cell syndromes (SCD). Participants included 74 African American children and adolescents with SCD and their primary caretakers. Outcomes included internalizing and externalizing behavior symptoms, as rated by caretakers, as well as intellectual abilities and academic achievement, as assessed by individually administered standardized instruments. Family functioning consisted of both caretaker adjustment and family environment (i.e., family adaptability and cohesion). Hierarchical multiple regression analyses revealed that caretaker psychological adjustment predicted externalizing behaviors, while family environment (i.e., adaptability and cohesion) predicted neither behavioral nor cognitive functioning. Socioeconomic variables alone predicted intellectual abilities and academic achievement and also contributed to the prediction of child behavioral adaptation. Results are discussed in terms of relevant sociocultural issues and implications for family-level prevention and intervention. 相似文献

Expressed emotion (EE) was examined, using the brief Five Minute Speech Sample measure, in families of (1) children with depressive disorders, (2) children with schizophrenia spectrum disorders, and (3) normal controls screened for the absence of psychiatric disorder. Consistent with the hypothesis of some specificity in the association between EE and the form of child disorder, rates of EE were significantly higher among families of depressed children compared to families of normal controls and families of children with schizophrenia spectrum disorders. Within the depressed group, the presence of a comorbid disruptive behavior disorder was associated with high levels of critical EE, underscoring the need to attend to comorbid patterns and subtypes of EE in future research.This research was supported by a grant from the John D. and Catherine T. MacArthur Foundation as part of their Network on Risk and Protective Factors in the Major Mental Disorders. The authors wish to express their appreciation to Sybil Zaden and Ana Magana-Amato for their assistance coding the FMSS-EE data, to Gwen Gordon for her assistance with data analysis, and to the families participating in the project. 相似文献

We conducted five studies with depressed patients, demographically matched controls, and college students to develop and psychometrically evaluate new measures of concerns about interpersonal relationships (sociotropy) and autonomous achievement (autonomy), constructs that have been proposed to confer vulnerability to depression. The final version of the Personal Style Inventory (PSI) Sociotropy and Autonomy scales showed a good factor structure, internal consistency reliability, and test-retest stability, a low correlation with each other, and weak or no gender differences. Convergent and discriminant validity were examined with respect to depressive symptom levels, the Dependency and Self-Criticism scales of the Revised Depressive Experiences Questionnaire, and a social desirability scale and were generally acceptable. Further evaluations of the construct validity of the PSI are indicated. 相似文献

...Rowland is a social scientist and a radical feminist, and she has undertaken the task of making readers think twice about reproductive technologies. If a reader isn't thinking twice, it will not do to blame it on Rowland and the shortcomings of her book. She has a good deal to say that is extremely important and that needs to be considered by anyone who is interested in the moral issues, in general, and the issues for women and children, in particular, that are raised by the new and emerging reproductive technologies. Her book should be widely read. And it should generate the worries it is written to generate. 相似文献

Kindergarten and first-grade children (6 and 7 years of age, respectively) were given specially designed discrimination tasks with introtact probes preceding each trial. One group (CON) was given the criterion task without prior training. A second group (LTL) received three pretraining tasks of the same type as the criterion task. A third group (HYP) received the same pretraining tasks, but with explicit instructions designed to teach a simple hypothesis-testing strategy. Several indices, designed to reflect the use of win-stay and lose-shift rules, as well as memory for disconfirmed hypotheses, were computed from the protocols of the criterion task. The indices for Group CON suggested that most of these children were using a guessing strategy that involved quite frequent changes in hypotheses. Moreover, many of these children restricted their hypotheses to the irrelevant cues. The indices for Group LTL revealed a spontaneous use of the hypothesis-testing strategy by nearly half of the children. The results for Group HYP indicated that over four-fifths of these children became highly efficient in the use of the problem-solving strategy. 相似文献
