Recent advances in molecular genetics and epigenetics are reviewed that have major implications for the bio-behavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the phenotype, and as a source of information in trying to predict phenotypes. The review is organized with respect to four basic processes by which phenotypes adapt to environmental challenges, with an emphasis on the data for humans: (1) developmental plasticity, (2) epigenetic mechanisms, (3) genotype-environment correlations, and (4) gene × environment interactions. 相似文献

One of the developmental tasks for the adolescent is to construct a new transitional space that leads to internal changes and adapts to the external world. When a nurturing matrix is unavailable, adolescents experience the entrance into the adult world as a dangerous transition. The author bases his arguments on psychoanalytic theories, mostly Winnicott's, and illustrates these with clinical material. He suggests that, even though these traumatized adolescents experienced nonfunctional transitional spaces, it is proven that they could be treated psychoanalytically. Here, the main task of the analyst is to establish a holding environment as a type of transference, resulting in less emphasis on interpretation of inner conflicts. 相似文献

Climate change is a wicked problem with causes and consequences overlapping with other wicked problems and no single solution (Hulme 2015). For example, the frequent droughts associated with climate change exacerbate another major problem facing humanity as we enter the Anthropocene: how to produce adequate food to feed a growing population without increasing pollution or “more food with low pollution (MoFoLoPo)” (Davidson et al. 2015). Soils represent an intersection of these two wicked problems, because they are integral to food production through agriculture and also are an important component of global climate models. Recent focus in the field of soil carbon cycling has facilitated a transformation in our understanding of the processes that control this important resource. This understanding is critical to responding to both wicked problems. 相似文献

Two principles, concerning (1) custodianship and (2) no retrospective right of ownership, will be fundamental to the just management of natural assets in future. Because natural assets are not man-made, the rights of ownership are not confined to the present generation that controls their exploitation. I have proposed an ethical requirement of custodianship towards future generations in which the present generation compensates future generations for the exploitation of natural assets by bequeathing the equivalent value of man-made assets. Because natural assets are discovered through a geological lottery, prior to search there is a natural veil of ignorance as to which locations will be endowed favourably and unfavourably. This creates a useful role for a polity to secure a just distribution of resource rents for all citizens rather than let them be dissipated through search and accrue highly unequally. But justice requires that ex post, well-endowed regions forfeit the right of ownership over those natural assets which have been discovered. Justice requires the rule of no retrospective right of ownership. 相似文献

The purpose of this study was to explore the conditions that make residences function as restorative environments for parents with young children. We analyzed how perceived restorativeness factors (being away, fascination, coherence, scope, and compatibility), the evaluation of the residence, interpersonal support, and the number of children contribute to actual psychological restoration in the residence using stepwise multiple regression. The results showed that perceived restorativeness factors needed for actual psychological restoration in residences depend on the working status and parental role. For nonworking mothers, fascination and interpersonal support significantly contributed to the prediction of their actual psychological restoration in the residence. For working mothers, only being away contributed significantly to predicting actual psychological restoration in the residence. For fathers, only compatibility contributed significantly to predicting actual psychological restoration in the residence. A need for future studies to examine whether the differences were caused by the fact that one is engaged in paid work or by the fact that potential stressors are distributed both inside and outside the residence was discussed. 相似文献

As the world becomes increasingly interconnected, exposure to global cultures affords individuals opportunities to develop global identities. In two studies, we examine the antecedents and outcomes of identifying with a superordinate identity—global citizen. Global citizenship is defined as awareness, caring, and embracing cultural diversity while promoting social justice and sustainability, coupled with a sense of responsibility to act. Prior theory and research suggest that being aware of one's connection with others in the world (global awareness) and embedded in settings that value global citizenship (normative environment) lead to greater identification with global citizens. Furthermore, theory and research suggest that when global citizen identity is salient, greater identification is related to adherence to the group's content (i.e., prosocial values and behaviors). Results of the present set of studies showed that global awareness (knowledge and interconnectedness with others) and one's normative environment (friends and family support global citizenship) predicted identification with global citizens, and global citizenship predicted prosocial values of intergroup empathy, valuing diversity, social justice, environmental sustainability, intergroup helping, and a felt responsibility to act for the betterment of the world. The relationship between antecedents (normative environment and global awareness) and outcomes (prosocial values) was mediated by identification with global citizens. We discuss the relationship between the present results and other research findings in psychology, the implications of global citizenship for other academic domains, and future avenues of research. Global citizenship highlights the unique effect of taking a global perspective on a multitude of topics relevant to the psychology of everyday actions, environments, and identity. 相似文献

The physical environment is thought to influence walking; however, daily variations in perceived environment have received little attention. The current study sought to examine if key within-person factors (i.e., implementation intentions, social support, affect and self-efficacy) would be associated with walking and if perceived access to supportive environments (e.g., access to nice walking paths) and perceived environmental barriers (e.g., bad weather and safety issues) were uniquely associated with walking after controlling for other constructs. Participants (N?=?14, 50.0% men, 78.6% White, M age?=?59.4?±?6.4) were in the intervention arm of an 8-week controlled trial promoting walking via personal digital assistants. Participants completed electronic surveys twice a day (total entries?=?804) in which they reported brisk walking levels and psychosocial and environmental factors. Multilevel modelling was used to examine within-person variations in constructs as determinants of walking. Results suggested that daily variations in implementation intentions, social support and positive affect were positively associated with walking. Further, perceived access to supportive environments, though not perceived environmental barriers, was positively associated with walking after controlling for other constructs (p?<?0.05). Future research should explore intervention components that target context-specific information about perceived access to supportive environments as part of a broader perspective on intervention development. 相似文献

Spatial knowledge, necessary for efficient navigation, comprises route knowledge (memory of the landmarks along a route) and survey knowledge (map-like). Available data on the retention in humans of spatial knowledge show that this does not decline systematically over months or years. Here, two groups of participants elaborated route and survey knowledge during navigation in a complex virtual environment before performing route and survey tasks. Both groups were tested 5 minutes after learning and 3 months later, while one group was also tested 1 week and 1 month later (repeated testing). Performance was similar in both groups on the first testing session, remained stable in the repeated tested group, but decreased in the non-repeated tested group, especially on route tasks. These results are the first to reveal a substantial and selective decline of spatial knowledge, occurring only if there is no possibility of reactivating knowledge along repeated testing. 相似文献
