It is widely acknowledged that metaphysical assumptions, commitments and presuppositions play an important role in science. Yet according to the empiricist there is no place for metaphysics as traditionally understood in the scientific enterprise. In this paper I aim to take a first step towards reconciling these seemingly irreconcilable claims. In the first part of the paper I outline a conception of metaphysics and its relation to science that should be congenial to empiricists, motivated by van Fraassen’s work on ‘stances’. There has been a considerable about of recent work devoted to van Fraassen’s ‘stance’ view, but it has not on the whole been noticed that the view has the potential to motivate a general empiricist conception of the relation between science and metaphysics. In the second and third sections I discuss two examples from biology to illustrate this conception: metaphysical punctuationism, and its relation to and influence on the thesis of punctuated equilibrium; and dialectical biology as defended by Levins and Lewontin.
In this paper we show the embedding of Hybrid Probabilistic Logic Programs into the rather general framework of Residuated Logic Programs, where the main results of (definite) logic programming are validly extrapolated, namely the extension of the immediate consequences operator of van Emden and Kowalski. The importance of this result is that for the first time a framework encompassing several quite distinct logic programming semantics is described, namely Generalized Annotated Logic Programs, Fuzzy Logic Programming, Hybrid Probabilistic Logic Programs, and Possibilistic Logic Programming. Moreover, the embedding provides a more general semantical structure paving the way for defining paraconsistent probabilistic reasoning with a logic programming semantics. 相似文献
The relation of seven coping dimensions to substance (tobacco, alcohol, marijuana) use was tested with a sample of 1,668 participants assessed at mean age 12.5 years and two yearly follow-ups. An associative latent-growth model showed one index of engagement (behavioral coping) to be inversely related to initial level of adolescent use and growth over time in peer use. Three indices of disengagement (anger coping, helpless coping, and hangout coping) were positively related to initial levels of peer use and adolescent use and to growth in adolescent use. Life stress was positively related to initial levels for peer use and adolescent use and to growth in adolescent use. Moderation tests indicated that effects of coping were significantly greater at higher level of stress; behavioral coping buffered the effects of disengagement. Effects of life stress were greater for girls than for boys. Results are discussed with reference to mechanisms of coping-substance use relationships. 相似文献
Adverse childhood experiences (ACEs) predict physical and mental health. We examined dyadic differences in intimate partner relationship health by ACE score among couples with low to moderate income enrolled in a relationship education program. Overall, we found a high prevalence of ACEs, disproportionate representation in the highest risk ACE group, and a significant effect between ACEs and indicators of mental and relational health. Implications for counselors include support for an ACE‐informed approach to couples counseling services, as well as a holistic and systemic view of mental and relational health. 相似文献
The complexity of homeless service users’ characteristics and the contextual challenges faced by services can make the experience of working with people in homelessness stressful and can put providers’ well‐being at risk. In the current study, we investigated the association between service characteristics (i.e., the availability of training and supervision and the capability‐fostering approach) and social service providers’ work engagement and burnout. The study involved 497 social service providers working in homeless services in eight different European countries (62% women; mean age = 40.73, SD = 10.45) and was part of the Horizon 2020 European study “Homelessness as Unfairness (HOME_EU).” Using hierarchical linear modeling (HLM), findings showed that the availability of training and supervision were positively associated with providers’ work engagement and negatively associated with burnout. However, results varied based on the perceived usefulness of the training and supervision provided within the service and the specific outcome considered. The most consistent finding was the association between the degree to which a service promotes users’ capabilities and all the aspects of providers’ well‐being analyzed. Results are discussed in relation to their implications for how configuration of homeless services can promote social service providers’ well‐being and high‐quality care. 相似文献
Couple therapy has been shown to be effective in randomized clinical trials; however, results from naturalistic couple therapy have been less consistent. This study utilized a benchmarking approach to compare the effectiveness of couple therapy in a community-based setting with findings from efficacy treatments, such as treatment within randomized clinical trials. The current study is the largest couple therapy sample published to date (N = 3,347 couples). Clients in couple therapy were asked to provide initial and weekly ratings of symptomology on the Outcome Questionnaire (OQ-45.2). We found that treatment effect sizes found at community clinics were smaller than efficacy studies (i.e., the benchmark). However, when taking into account measurement reactivity, the effect sizes were comparable. This is the first benchmarking study for community-based couple therapy, allowing for meaningful comparisons and understanding of outcomes in real-world couple therapy. Implications for the field are offered in terms of evaluating community-based psychotherapy studies with benchmarking for couple therapy. Results of this study provide clinicians and researchers a way to meaningfully compare couple therapy outcomes, accounting for differences in community-based practices and randomized clinical trials. This benchmark also underscores the impact of measurement sensitivity, an issue commonly overlooked in psychotherapy research and practice. 相似文献
