David Lewis insists that restrictivist composition must be motivated by and occur due to some intuitive desiderata for a relation R among parts that compose wholes, and insists that a restrictivist??s relation R must be vague. Peter van Inwagen agrees. In this paper, I argue that restrictivists need not use such examples of relation R as a criterion for composition, and any restrictivist should reject a number of related mereological theses. This paper critiques Lewis and van Inwagen (and others) on their respective mereological metaphysics, and offers a Golden Mean between their two opposite extremes. I argue for a novel account of mereology I call Modal Mereology that is an alternative to Classical Mereology. A modal mereologist can be a universalist about the possible composition of wholes from parts and a restrictivist about the actual composition of wholes from parts. I argue that puzzles facing Modal Mereology (e.g., puzzles concerning Cambridge changes and the Problem of the Many, and how to demarcate the actual from the possible) are also faced in similar forms by classical universalists. On my account, restricted composition is rather motivated by and occurs due to a possible whole??s instantiating an actual type. Universalists commonly believe in such types and defend their existence from objections and puzzles. The Modal Mereological restrictivist can similarly defend the existence of such types (adding that such types are the only wholes) from similar objections and puzzles. 相似文献

This study examined the relation between mothers' perception of their capacity for controlling infant crying and a later measure of parent-toddler social interaction-compliance with parental requests. Fifty-seven mothers participated in (a) a laboratory task when their children were 5 months old to assess mothers' perception of control and (b) a toy-cleanup task when their children were 24 months old to assess toddler compliance. Perception-of-control scores on the laboratory task reflected accuracy of perception and ranged from accurate to greatly overestimating control, with an overestimation referred to as an illusion of control. Mothers were categorized into three illusion-of-control groups: low, moderate, and high. Toddlers of mothers in the low and high illusion-of-control groups were more likely to be categorized as highly defiant than were toddlers of mothers in the moderate-illusion group. Mothers with high illusory control were most likely to use a high power-assertion strategy (negative control), and when negotiating, their toddlers' expression of autonomy was most likely to escalate into defiance. 相似文献

The threat of separation from a parent theoretically increases the risk of adolescent suicide attempts. The present study evaluated this and other hypothesized risk factors in a sample of adolescent suicide attempters and nonsuicidal controls, using the Psychiatric Consultation Checklist (Lyon, 1987). Stepwise logistic regression was used to predict group membership. It was found that threat of separation from a parental figure, insomnia, neglect, substance abuse, suicidal ideation, and failing grades were the strongest predictors of suicide attempt. Ten predictor variables correctly identified 97% of suicide attempters and 86% of nonattempters. Unexpected findings included high levels of truancy, threatening others, and separation from a parent before the age of 12 among nonattempters. 相似文献

The development of the cerebral cortex requires large-scale movement of neurons from areas of proliferation to areas of differentiation and adult function in the cortex proper, and the patterns of this neuronal migration are surprisingly complex. The migration of neurons is affected by several naturally occurring genetic defects in humans and mice; identification of the genes responsible for some of these conditions has recently yielded new insights into the mechanisms that regulate migration. Other key genes have been identified via the creation of induced mutations that can also cause dramatic disorders of neuronal migration. However, our understanding of the physiological and biochemical links between these genes is still relatively spotty. A number of molecules have also been studied in mice (Reelin, mDab1, and the VLDL and ApoE2 receptors) that appear to represent part of a coherent signaling pathway that regulates migration, because multiple genes cause an indistinguishable phenotype when mutated. On the other hand, two human genes that cause lissencephaly (LIS1, DCX) encode proteins that have recently been implicated as regulators or microtubule dynamics. This article reviews some of the mutant phenotypes in light of the mechanisms of neuronal migration. MRDD Research Reviews 6:34-40, 2000. 相似文献

The purpose of this study was to examine the severity of behavioral and emotional problems among adolescents with poor and typical single word reading ability (N = 188) recruited from public schools and followed for a median of 2.4 years. Youth and parents were repeatedly assessed to obtain information regarding the severity and course of symptoms (depression, anxiety, somatic complaints, aggression, delinquent behaviors, inattention), controlling for demographic variables and diagnosis of ADHD. After adjustment for demographic variables and ADHD, poor readers reported higher levels of depression, trait anxiety, and somatic complaints than typical readers, but there were no differences in reported self-reported delinquent or aggressive behaviors. Parent reports indicated no differences in depression, anxiety or aggression between the two groups but indicated more inattention, somatic complaints, and delinquent behaviors for the poor readers. School and health professionals should carefully assess youth with poor reading for behavioral and emotional symptoms and provide services when indicated. 相似文献

There has been increasing interest in family-centered, collaborative, biopsychosocial models of care by health and mental health professionals and consumers. This trend has led to growing demand and development of specialized training in family systems approaches to health care. This article describes the Families, Illness, and Collaborative Healthcare programs developed at the University of Chicago affiliate, the Chicago Center for Family Health. The program philosophy is guided by the following principles: a systems orientation focused on the family, a Family Systems Illness Model, a family resilience framework, a family-centered collaborative model of health care, and a social justice and advocacy orientation. Specific training components that implement these principles are described, including intensive certificate and fellowships; workshops, conferences, and institutes; and consultation and training services for community-based organizations. Discussion includes professional networking opportunities, funding challenges, and policy recommendations. 相似文献

Evidence for the Continuity of Early Problem Behaviors: Application of a Developmental Model 总被引:9,自引:0,他引:9

Evidence of the continuity of early problem behaviors in young girls and boys was examined developmentally. Data were gathered on 104 mother-child dyads from low-income families when children were between 1 and 5 years of age. Difficult temperament, aggression, and noncompliance from 12 to 24 months, and externalizing and internalizing problems at 36 and 60 months, were assessed. The results provide evidence for the continuity of early behavioral and emotional problems and support for the early differentiation between internalizing and externalizing problems. Implications of the current findings for prevention efforts are presented. 相似文献

In sum, the research in 1978 was diverse and of good quality and quantity. However, there continues to be a clear need for longitudinal research of all kinds (in particular on the career development process) and a need for additional research with the employed adult population, although the past few years demonstrate improvement in the latter area.In 1978 the most productive research area as suggested by this review was associated with the women's movement and manifested by research primarily on sex stereotyping and women's careers. Ranking second was the topic of theoretical developments in vocational behavior led by the research on Holland's constructs. These two research trends accounted for about 50 studies; 26 and 24, respectively. Job satisfaction assumed the third position with some concentration on satisfaction and work motivation. Next and very much clustered were life-span aspects, assessment, and job performance. Each of these research themes stimulated about 17 studies that were reviewed here. Vocational interventions and race differences received moderate attention while job interview variables and occupational environments sparked very limited work in the more psychologically oriented journals.The major contributor to the 1978 review was of course the Journal of Vocational Behavior (62 studies), followed by the Journal of Applied Psychology (25 studies). Five other journals contributed an average of about 10 studies. These were the Journal of Counseling Psychology, Journal of Measurement and Evaluation in Guidance, the Journal of Organizational Behavior and Human Performance, Personnel Psychology, and the Vocational Guidance Quarterly. These appear to be the major journals publishing work on vocational behavior and career development.Finally, the volume of research on vocational psychology continued on an upward trend in 1978. This review and the previous reviews (Betz, 1977; Osipow, 1976; Zytowski, 1978) clearly document this trend. 相似文献
