The literature on quantum logic emphasizes that the algebraic structures involved with orthodox quantum mechanics are non distributive. In this paper we develop a particular algebraic structure, the quasi-lattice ( \mathfrakI{\mathfrak{I}}-lattice), which can be modeled by an algebraic structure built in quasi-set theory \mathfrakQ{\mathfrak{Q}} . This structure is non distributive and involve indiscernible elements. Thus we show that in taking into account indiscernibility as a primitive concept, the quasi-lattice that ‘naturally’ arises is non distributive.  相似文献

Complex relationships exist between eating behaviour and personal and environmental factors. Rural and urban geographic contexts seem to play a role in eating behaviour, and therefore deserve a deeper study. A healthy eating behaviour and the conditions that promote it are a major issue in the promotion of adolescent health. The study aims to investigate the associations between the area of residence (urban vs. rural), self‐regulation strategies (TESQ‐E) and eating behaviours among children and adolescents. A total of 11,820 adolescents (50.6% girls) participated in the study, with a mean age of 13.30 years (SD= 2.13). Nine countries (The Netherlands, United Kingdom, Poland, Portugal, Denmark, Romania, Germany, Finland and Belgium) completed a questionnaire in the school context, asking about the use of self‐regulation strategies, eating behaviour awareness/care and sociodemographic questions such as age, gender and residential area. Both areas of residence (urban vs. rural) are associated with eating awareness/care in Romania and Portugal, controlling for age, gender and self‐regulation strategies. In some European countries at least, and most probably around the world, health promotion should focus on an ecological approach that includes the understanding of the effect of both environmental factors and personal skills on eating behaviour/awareness.  相似文献

Adolescence is characterized by extensive neural development and sensitivity to social context, both of which contribute to engaging in prosocial behaviors. Although it is established that prosocial behaviors are linked to positive outcomes in adulthood, little is known about the neural correlates of adolescents’ prosociality. Identifying whether the brain is differentially responsive to varying types of social input may be important for fostering prosocial behavior. We report pilot results using new stimuli and an ecologically valid donation paradigm indicating (1) brain regions typically recruited during socioemotional processing evinced differential activation when adolescents evaluated prosocial compared with social or noninteractive scenes (N = 20, ages 13–17 years, MAge = 15.30 years), and (2) individual differences in temporoparietal junction recruitment when viewing others’ prosocial behaviors were related to adolescents’ own charitable giving. These novel findings have significant implications for understanding how the adolescent brain processes prosocial acts and for informing ways to support adolescents to engage in prosocial behaviors in their daily lives.  相似文献

This study aimed to examine the mediating role of rumination, experiential avoidance, dissociation and depressive symptoms in the association between daily peer hassles and non-suicidal self-injury among adolescents. Additionally, this study explored gender differences in these associations and tested whether the proposed model was invariant across genders. The sample consisted of 776 adolescents, of them 369 are males (47.6%) and 407 are females (52.4%), aged between 12 and 18 years old from middle and high schools in Portugal. Participants completed self-report questionnaires to assess daily peer hassles, rumination in its severe component (i.e., brooding), experiential avoidance, dissociation, depressive symptoms and non-suicidal self-injury. Path analysis showed that daily peer hassles indirectly impact on non-suicidal self-injury through increased levels of brooding, experiential avoidance, dissociation, and depressive symptoms. Results indicated significant gender differences in mean scores and path analysis. Male adolescents were more likely to engage in brooding and experiential avoidance in response to external distress (particularly, daily peer hassles), whereas female adolescents were more likely to engage in non-suicidal self-injury in response to internal distress (particularly, depressive symptoms). These findings suggest relevant preventive and intervention actions to address emotion dysregulation in adolescence, by teaching them acceptance and mindfulness skills as a way of coping with stressful experiences and internal distress.  相似文献

Recent research has found that a strong family allocentrism relates to reduced adolescent depressive symptoms. Besides providing continuous support for this relation, this research extended the scope by exploring whether there was a U-shaped association between family allocentrism and depressive symptoms and testing the mediation effect of identity style among Italian adolescents (N?=?387, 183 boys, 204 girls, Mage?=?16.38 years). Result of hierarchical regression model showed that the association between family allocentrism and depressive symptoms was linear rather than U-shaped. More importantly, this linear relation was mediated by normative and diffuse-avoidant style. In sum, the current findings suggest that adolescents who are allocentric toward family tend to follow family members’ expectations to establish self-identity and deal with identity issues more proactively, and thus they are less likely to experience depressive symptoms. Moreover, there is no significant evidence that too much family allocentrism would lead to elevated depressive symptoms.  相似文献

Candomble, a Brazilian religion of African origin that worships Orishas, promotes “healing” assistance during its worship rituals using therapy with plants and beliefs. From its ancestry tradition, the respect and beware with nature are expressed. Therefore, the aim of this study is to investigate the perception of ethnoecology and health promotion among Candomble practitioners from a Candomble temple in the state of Ceará, Brazil. The ethnography was designed to allow greater immersion into the current mystique. This immersion results in the breaking of existing prejudices and admiration for their worldview. Thus, it can be observed that people seek Candomble to get rid of “bad” health difficulties, such as insomnia, depression, eyesight problems among others, which are commonly treated with herbal preparations, baths, and teas, using plants native to the region; however, their indications are not always in accordance with scientific evidence. In parallel with biomedicine, their hospitable and healthcare practices are considered by most as the equivalent to traditional healthcare actions, but greater recognition of biomedicine is necessary. Based on this perspective, the use of native plants in Candomble is examples of memory, hospitality, and humanization for the community wellness.  相似文献

Using longitudinal data collected at four time points from 191 dyads of Mexican‐origin adolescent first‐time mothers and their mother figures, we examined changes in and socialization of traditional gender role attitudes across the transition to parenthood using latent growth curve modeling and actor – partner interdependence modeling. Longitudinal growth models indicated that, regardless of nativity status, adolescent mothers' and their foreign‐born mother figures' gender role attitudes became more egalitarian across adolescents' transition to parenthood, spanning from the 3rd trimester of pregnancy to 36 months postpartum. Furthermore, actor‐partner interdependence modeling suggested that adolescents' and their mother figures' gender role attitudes during adolescents' third trimester of pregnancy equally contributed to subsequent increases in one another's gender role attitudes at 10 months postpartum. Importantly, this reciprocal socialization process was not moderated by adolescent mothers' nor by their mother figures' nativity status. Findings suggest that it is important to understand the cultural and intergenerational family processes that contribute to the development of gender role attitudes during the transition to parenthood for adolescent mothers and their mother figures in Mexican‐origin families.  相似文献

In the current study, I describe values for gender roles and cross‐sex relations among adolescents growing up in a southern Mexican Maya community in which high school was introduced in 1999. A total of 80 adolescent girls and boys, half of whom were attending the new high school, provided their opinions on two ethnographically derived vignettes that depicted changes in gender roles and relations occurring in their community. Systematic coding revealed that adolescents not enrolled in high school tended to prioritise ascribed and complementary gender roles and emphasise the importance of family mediation in cross‐sex relations. Adolescents who were enrolled in high school tended to prioritise equivalent and chosen gender roles, and emphasised personal responsibility and personal fulfillment in cross‐sex relations. Perceptions of risks and opportunities differed by gender: girls favourably evaluated the expansion of adult female role options, but saw risks in personal negotiations of cross‐sex relations; boys emphasised the loss of the female homemaker role, but favourably evaluated new opportunities for intimacy in cross‐sex relations.  相似文献

Cognitive enhancement strategies have gained recent popularity and have the potential to benefit clinical and non-clinical populations. As technology advances and the number of cognitively healthy adults seeking methods of improving or preserving cognitive functioning grows, the role of electronic (e.g., computer and video game based) cognitive training becomes more relevant and warrants greater scientific scrutiny. This paper serves as a critical review of empirical evaluations of publically available electronic cognitive training programs. Many studies have found that electronic training approaches result in significant improvements in trained cognitive tasks. Fewer studies have demonstrated improvements in untrained tasks within the trained cognitive domain, non-trained cognitive domains, or on measures of everyday function. Successful cognitive training programs will elicit effects that generalize to untrained, practical tasks for extended periods of time. Unfortunately, many studies of electronic cognitive training programs are hindered by methodological limitations such as lack of an adequate control group, long-term follow-up and ecologically valid outcome measures. Despite these limitations, evidence suggests that computerized cognitive training has the potential to positively impact one’s sense of social connectivity and self-efficacy.  相似文献
