OBJECTIVE: With behavior genetic analyses of data from young adult twins, we evaluated theoretical perspectives that differentially emphasize biological dispositions, social/cultural factors, or universal pathways to explain individual differences in sexual behaviors. DESIGN: We fit biometric sex limitation models to three aspects of sexual behavior reported by 4,925 Finnish twins ages 23-27. MAIN OUTCOME MEASURE: From a postal questionnaire, we obtained self-report information on initiation/abstinence of sexual intercourse, onset age, and number of sexual partners. RESULTS: Genetic and non-shared environmental influences were significant for all three measures. There were trends for common environmental influences on initiation and, in females, age at first intercourse. Some differential effects in males and females were found. Results comparing onset age and number of partners among experienced twins from pairs concordant and discordant for initiation found genetic and environmental influences on initiation/abstinence overlapped those found for the other aspects of sexual behavior. CONCLUSIONS: These results document genetic variation in individual differences in sexual behavior of young adults. Incorporating genetic dispositions into integrated models of sexual behavior will facilitate more effective health promotion and risk taking intervention. 相似文献

This study investigated attachment‐related behavioural problems and their change over time among internationally adopted toddlers (N = 171, boys 40%) in Finland. The parents filled in questionnaires posted in 2007 and again in 2009. At the baseline (on average, 1.9 years from adoption), the mean age of the adoptees was 2.8 years. The comparison group (N = 244, boys 46%) was collected through well‐baby clinics. Results from the paired t‐test and mixed models showed that the adoptees' attachment‐related behavioural problems decreased during the 2‐year follow‐up and that they did not manifest more problems than their age‐mates any more 4 years after adoption. The decrease in behavioural problems was associated with the child's female gender, country of origin and adoptive parents' positive experience about adoption. A child's stereotypic or self‐injurious behaviour was not associated with the change in attachment‐related behaviour over time, although both were associated with behavioural problems.

The Embodied Attunement of Therapists and a Couple within Dialogical Psychotherapy: An Introduction to the Relational Mind Research Project

In dialogical practice, therapists seek to respond to the utterances of clients by including in their own response what the client said. No research so far exists on how, in dialogs, therapists and clients attune themselves to each other with their entire bodies. The research program The Relational Mind is the first to look at dialog in terms of both the outer and the inner dialogs of participants (clients and therapists), observed in parallel with autonomic nervous system (ANS) measurements. In the ANS, the response occurs immediately, even before conscious thought, making it possible to follow how participants in a multiactor dialog synchronize their reactions and attune themselves to each other. The couple therapy case presented in this article demonstrates how attunement is often not a simple “all at the same time” phenomenon, but rather a complex, dyadic or triadic phenomenon which changes over time. In the case presented, there was strong synchrony between one therapist and one client in terms of their arousal level throughout the therapy session. It was also observed that high stress could occur when someone else was talking about something related to the participant, or if that person mirrored the participant's words. Overall, it seems that in evaluating the rhythmic attunement between therapists and clients it is not enough to look at single variables; instead, integrated information from several channels is needed when one is seeking to make sense of the embodiment. 相似文献

To assess genetic and environmental contributions to personal goals, 1279 twins aged 20-26 filled in Personal Project Analysis and NEO-FFI inventories. Personal goals relating to education, the respondent’s own family, friends, property, travel and self showed primarily genetic and unique environmental effects, whereas goals related to parents and relatives showed both shared and unique environmental effects. The variation in goals related to health, work, hobbies and life philosophy was attributable to non-shared environmental effects. Openness to experience and personal goals related to family, education and property shared a significant amount of genetic influence. The same was true for extraversion and self-related goals, and agreeableness and goals related to property. 相似文献

In a definition (∀x)((xєr)↔D[x]) of the set r, the definiens D[x] must not depend on the definiendum r. This implies that all quantifiers in D[x] are independent of r and of (∀x). This cannot be implemented in the traditional first-order logic, but can be expressed in IF logic. Violations of such independence
requirements are what created the typical paradoxes of set theory. Poincaré’s Vicious Circle Principle was intended to bar
such violations. Russell nevertheless misunderstood the principle; for him a set a can depend on another set b only if (bєa) or (b ⊆ a). Likewise, the truth of an ordinary first-order sentence with the G?del number of r is undefinable in Tarki’s sense because the quantifiers of the definiens depend unavoidably on r. 相似文献

The article focuses on examining the distinct nature of persecution. In the article I argue that on the grounds of common historical cases of persecution an account of the core components of the concept may be established. The core comprises three central elements: asymmetrical and systemic threat, severe and sustained harm, and unjust discriminatory targeting. I will conclude the paper by suggesting that none of the components alone make persecution anything distinct. However, the simultaneous occurrence of the components may be argued to amount to a separable class of harms that are among the worst-case scenarios for those having to endure them. 相似文献

This paper aims to provide Humean metaphysics for the interventionist theory of causation. This is done by appealing to the hierarchical picture of causal relations as being realized by mechanisms, which in turn are identified with lower‐level causal structures. The modal content of invariances at the lowest level of this hierarchy, at which mechanisms are reduced to strict natural laws, is then explained in terms of projectivism based on the best‐system view of laws. 相似文献
