Mechanistic philosophy of science views a large part of scientific activity as engaged in modelling mechanisms. While science textbooks tend to offer qualitative models of mechanisms, there is increasing demand for models from which one can draw quantitative predictions and explanations. Casini et al. (Theoria 26(1):5–33, 2011) put forward the Recursive Bayesian Networks (RBN) formalism as well suited to this end. The RBN formalism is an extension of the standard Bayesian net formalism, an extension that allows for modelling the hierarchical nature of mechanisms. Like the standard Bayesian net formalism, it models causal relationships using directed acyclic graphs. Given this appeal to acyclicity, causal cycles pose a prima facie problem for the RBN approach. This paper argues that the problem is a significant one given the ubiquity of causal cycles in mechanisms, but that the problem can be solved by combining two sorts of solution strategy in a judicious way. 相似文献

In this article I describe a mental health programme that has clear, though unstated, adumbrations of the spiritual practice of mindfulness. The programme has been successful in the southern USA, an area noted for its religious and political conservatism. I provide a background of the historical, political, cultural and religious situation affecting spiritual education in the USA with which such programmes contend. Research methodologies include historical research, text analysis and personal interviews. 相似文献

As evidence-based practice is becoming integrated into children’s mental health services as a means of improving outcomes for children and youth with severe behavioral and emotional problems, therapeutic foster care (TFC; a specialized treatment approach for such youth) is one of few community-based programs considered to be evidence-based. “Together Facing the Challenge” (TFTC) which was tested in a randomized trial of TFC has been identified as an evidence-based model. We describe the experiences reported by one of the agencies that participated in our study and how they have incorporated TFTC into their on-going practice. We highlight key implementation strategies, challenges faced, and lessons learned as the agency moved forward towards full implementation of TFTC. 相似文献

The aim of the present study was to investigate positive body image during adolescence. Semi-structured interviews, centring on three body image domains (satisfaction with own appearance, views on exercise, and influence from family and friends) were conducted with 30 early adolescent Swedish girls and boys who at age 10 and 13 had shown the highest level of body satisfaction in a large longitudinal sample. The data were analyzed thematically. Results revealed that the adolescents’ satisfaction with their own appearance was characterized by a functional view of the body and an acceptance of the bodily imperfections that they perceived that they had. The vast majority of the adolescents were physically active and found exercise joyful and health-promoting. Finally, although some of the adolescents had received negative comments about their appearance from family and friends, such comments were not given any importance. 相似文献

This investigation assessed prospective bases of non-human primate cognitive operations that support serial list memory. Four
macaques learned 3-, 5-item ordered lists of objects (as two-choice problems) and then either did or did not (in a within-subject
design) receive training on pairs that linked the three original lists into a 15-item serial order. Next, subjects experienced
selective exposure trials on object pairs that either maintained or contrasted to the serial position relationships seen during
original learning. Subsequent comprehensive tests assessed the interactive effects of linking and exposure conditions on choosing
in accord with a combined 15-item serial order. Linking readily induced monkeys to merge lists into a 15-item order, but restricting
early exposure to pairs with the same positional relationships as original training slowed, but did not prevent, list combination.
Exposure to positional relationships congruent with the combined (15-item) list and different from those of original 5-item
training aided both expression of the linking effect and acquisition after no link training. Thus, list linking facilitated
serial reorganization by inducing release from error derived from memory for prior learned positional relationships. The task
was recommended as a prospective evaluator of continuity of cognitive processes among species. 相似文献

Some scholars include changes in spirituality, such as a greater commitment to their religious beliefs or an enhanced understanding of spiritual matters, in the definition of posttraumatic growth; others conclude that questions of spirituality should be excluded from this definition. This article highlights the fundamental difference of religion to other domains of posttraumatic growth because religions are ideologies (and other domains of growth are not). As ideologies, it is argued that religions can affect different levels of identity in different ways. Based on testimonial evidence from Rwandan genocide survivors, the article demonstrates that although religious beliefs can bring existential comfort at the individual level, they can also lead to a state of false consciousness at the collective level. In Rwanda, the dominant religious ideology facilitated the spiritual and moral climate in which genocide became possible. Today, religious interpretations of the Rwandan Patriotic Front's (RPF) leadership provide spiritual backing to a government which has become increasingly authoritarian. 相似文献

Positive Automatic Cognitions Mediate the Relationship Between Personality and Trait Positive Affect

Positive affect (PA) has emerged as a key well-being facet and a powerful predictor of physical and psychological well-being. One of the strongest predictors of PA is personality, particularly neuroticism and extraversion. However, the mechanisms via which personality affects PA are not well-understood. Consistent with theories that accord cognitive factors a role in mediating the relationship between personality and outcomes, we tested whether positive automatic thoughts (PATs) mediated the relationship between neuroticism, extraversion, and PA among 199 college students (137 women, 70% White, 66% first and second year students, mean age = 24.13, SD = 8.86). Consistent with hypotheses, structural equation modeling indicated that PATs fully mediated the relationship between both neuroticism and extraversion and PA. The structural model fit the data well, χ2/df = 2.33, CFI = .96, SRMR = .07, RMSEA = .08 (90% CI: .06, .10), AIC = 172.45, and accounted for 58% of the variance in PA. An alternative model in which personality predicted PA, which in turn predicted PATs, did not provide as good a fit to the data, χ2/df = 3.03, CFI = .94, SRMR = .09, RMSEA = .10 (90% CI: .08, .12), AIC = 207.40. Models in which negative automatic thoughts (NATs) were construed as fully [χ2/df = 4.46, CFI = .95, SRMR = .08, RMSEA = .13 (90% CI: .11, .16)] or partially [χ2/df = 4.04, CFI = .96, SRMR = .06, RMSEA = .12 (90% CI: .10, .15)] mediating the relationship between neuroticism and negative affect did not provide a good fit to the data. A final model in which negative affect was tested a mediator of the relationship between neuroticism and NATs also did not fit the data well, χ2/df = 4.03, CFI = .96, SRMR = .07, RMSEA = .12 (90% CI: .10, .15). 相似文献

The study investigated the nature and prevalence of self-reported childhood sexual abuse (CSA) among a sample of Zimbabwean girls and college students. A total of 1059 high school girls and college students with a mean age (M = 18.31, SD = 3.66) participated in study. Overall, a CSA prevalence rate of 41.26% was found. The highest CSA prevalence rate was found among respondents who resided on commercial farms and mines (53%). Respondents who lived with their biological parents during childhood were significantly less likely to be sexually abused than were respondents who lived with non-parents such as uncles and brothers-in-law. Only 7.22% of the perpetrators were strangers. This study shows that sexual abuse of children in Zimbabwe is rampant, multifaceted, and linked to cultural factors that must be addressed as part of efforts to confront this scourge. 相似文献
