We develop a general method for applying functional models to natural systems and cite recent progress in protein modeling
that demonstrates the power of this approach. Functional modeling constrains the range of acceptable structural models of
a system, reduces the difficulty of finding them, and improves their fidelity. However, functional models are distinctly different
from the structural models that are more commonly applied in science. In particular, structural and functional models ask
different questions and provide different kinds of answers. As we clarify these differences and articulate how to use these
models jointly, we extend our ability to do science and gain insight into the proper use of the terms organization, order, and emergence when describing systems in nature. 相似文献

We tested a model of mothers' parenting efficacy and attributions for child ADHD behaviors as predictors of experiences with behavioral treatment. The model proposed that mothers' beliefs regarding the acceptability and effectiveness of behavioral strategies would intervene between mothers' cognitions about parenting and child behavior and their treatment experiences. Participants were 101 mothers of 5- to 10-year-old children (82% male) with ADHD. Mothers reported their parenting efficacy and attributions for child behavior, and then received a single session of treatment teaching 2 behavior management strategies. Then, mothers reported their beliefs regarding the acceptability and effectiveness of these strategies. A follow-up phone interview 1 week later assessed mothers' experiences in using the behavioral strategies. The overall model fit the data. Attributions of child ADHD behavior as more pervasive, enduring, and within the child's control were related to seeing behavioral treatment as more acceptable, but neither attributions nor treatment acceptability predicted treatment experience. However, mothers with higher parenting efficacy viewed the behavioral strategies as more likely to be effective, and this pathway significantly predicted positive treatment experience. Implications for understanding the variables that contribute to parental decision-making and treatment participation for childhood ADHD are considered. 相似文献

Multiculturalism constitutes an important element of school climate, but the relation between perceived multiculturalism and academic achievement has not been widely studied. This study examined the influence of students' perceptions of school support for multiculturalism on academic achievement among 280 Asian American and Hispanic youth, including ethnic identity and ethnocultural empathy as potential mediators. Results of structural equation modeling revealed that perceived multiculturalism was significantly positively related to ethnocultural empathy for Asian Americans and Hispanics, and that ethnocultural empathy, in turn, was predictive of academic achievement for Hispanics only. Results of bootstrapping to test for mediation effects revealed ethnocultural empathy to be a salient mediator for Hispanic youth. Although ethnic identity did not mediate the link between multiculturalism and academic achievement, ethnic identity was significantly predictive of achievement for Hispanics. On the whole, these findings suggest that fostering a school climate supportive of multiculturalism may improve empathy toward ethnic out-groups. Furthermore, schools that promote compassion and tolerance for diverse ethnic groups may achieve better academic outcomes among Hispanic youth. 相似文献

It is widely accepted that adults show an advantage for deontic over epistemic reasoning. Two published studies (Cummins, 1996b; Harris and Núñez, 1996, Experiment 4) found evidence of this “deontic advantage” in preschool-aged children and are frequently cited as evidence that preschoolers show the same deontic advantage as adults. However, neither study has been replicated, and it is not clear from either study that preschoolers were showing the deontic advantage under the same conditions as adults. The current research investigated these issues. Experiment 1 attempted to replicate both Cummins’s and Harris and Núñez’s studies with 3- and 4-year-olds (N = 56), replicating the former with 4-year-olds and the latter with both 3- and 4-year-olds. Experiment 2 modified Cummins’s task to remove the contextual differences between conditions, making it more similar to adult tasks, finding that 4-year-olds (n = 16) show no evidence of the deontic advantage when no authority figure is present in the deontic condition, whereas both 7-year-olds (n = 16) and adults (n = 28) do. Experiment 3 removed the authority figure from the deontic condition in Harris and Núñez’s task, again finding that 3- and 4-year-olds (N = 28) show no evidence of the deontic advantage under these conditions. These results suggest that for preschoolers, the deontic advantage is reliant on particular contextual cues such as the presence of an authority figure, in the deontic condition. By 7 years of age, however, children are reasoning like adults and show evidence of the advantage when no such contextual cues are present. 相似文献

This paper surveys the field of Judaism and health. The authors trace the history of discourse on health and healing within
Judaism, from the biblical and rabbinic eras to contemporary research and writing on Jewish bioethics, pastoral care, communal
services, and aging, including congregational and community programming related to health and illness and the emergence of
the Jewish healing movement. The work of the Kalsman Institute on Judaism and Health is described, focusing on efforts to
unite these various threads into a scholarly field emphasizing basic and applied research on the instrumental functions of
Jewish religious life for health and well-being. 相似文献

An important factor in a girl’s feelings about menstruation as well as psychological outcomes is the timing of menarche. Reaching menarche early compared to one’s peers has been implicated as a risk factor for multiple negative outcomes including depression, delinquency, body dissatisfaction, and substance abuse. Early menarche also involves a convergence of biological and contextual factors that interact to influence psychological outcomes. In this paper we first review the biology of menarche. Drawing from studies conducted in the U.S. as well as European nations and New Zealand, we synthesize the research on environmental factors that contribute to early menarche, as well as evidence that early menarche changes a girl’s social environment. Then we review the hormonal influence hypothesis, the maturation disparity hypothesis, the contextual amplification hypothesis, and the accentuation hypothesis as models that may explain the mechanisms by which early menarche contributes to negative psychological outcomes. Finally, we describe how both mediation and moderation models can be used to understand the processes that link early menarche to adverse outcomes. 相似文献

This study measures premarital sex prevalence, sources of sex education, and support for secular sex education among 151 newly married young adults surveyed at 9 Texas Southern Baptist churches. More than 70% of respondents reported having had premarital vaginal or oral sex, but more than 80% regretted premarital sex. The proportion of premarital sex exceeded 80% in 6 of 9 churches, among men and women married after age 25 and women married before age 21. School sex education was the only source of information about sexually transmitted infections for 57% of respondents, and 65% supported secular sex education despite church opposition. 相似文献

Background: Modern technologies that offer an alternative to face‐to‐face therapy have gained ground in the NHS. Critics have argued that some of the important elements of the therapeutic change process necessarily require a human therapist. Yet, the traditional understanding of the change process in psychotherapy is challenged by evidence that some computerised cognitive behaviour therapy (cCBT) programs may be as effective as face‐to‐face therapy, suggesting that in certain cases the interaction between user and a cCBT product satisfies sufficient criteria for personal change without the need for actual human contact. Aim: This study used the cCBT package Blues Begone as a means of investigating the process by which a computer‐mediated program helped adults with mild depression help themselves. Method: Seven qualitative interviews were conducted with mildly depressed users who had completed Blues Begone in their own homes without any additional human help or support. Findings: Interpretive phenomenological analysis (IPA) was performed with four main themes emerging. These were: the meaningful relationship; shape from confusion; stimulation and empowerment. This study illustrates some of the ways that some depressed users make use of cCBT self help. 相似文献
