Much of what we need to plan for our survival is already known, but what we know, how we know, and who knows is divided up between disciplines. Thus much of the problem of ensuring our survival is a matter of learning across the disciplines. We identify four modes through which we bring disciplinary knowledge together: the unity of science, integrated assessment, heuristic models, and distributed learning networks. Although none of them are perfect, we can learn how to put our knowledge together across the disciplines much better than we do.  相似文献

The vocationally-indecisive individual presents a major counselling problem. The theory and research behind career indecision is discussed and a counselling approach based on identity formation is outlined. Four identity statuses — Identity Achievements, Foreclosures, Identity Diffusions, and Moratoriums — are described and counselling approaches for each are explored.  相似文献

This paper reviews the research into a specific aspect of neardeath experiences (NDEs): the prophetic vision (PV). PVs are subjectively compelling flashforwards of planetary-wide cataclysms and eventual regeneration that sometimes occur during or in the immediate aftermath of an NDE. Previous research has shown that the most frequently mentioned year for the culmination of the geophysical calamities foreseen in PVs was 1988. I argue that PVs should be understood as manifestations of a collective prophetic impulse that historically tends to arise during periods of cultural crisis. PVs are thus expressions of the felt need for cultural renewal and therefore should not be taken literally as prognostic of drastic physical changes on Earth.  相似文献

A computer-controlled system that detects spontaneous activity (locomotion and rearing) and diurnal activity rhythms in small animals is described. Automatic recording of subtotals during test periods provides data about habituation (nonassociative learning). The system is relatively inexpensive to construct. Fabricated from highly reliable circuit components, it provides replicable measures that enable comparisons between different experimental treatments to be made using parametric statistics.  相似文献

Conversion within the Mexican-descent, Catholic community of the United States is a reinforcement of existing values through a recommitment to the worldview of this people by means of an explicit, personal and public retrieval of its kinetics achieved by an innovative adaptation of its formal themes. Three rites of this community's popular spirituality are analyzed in order to discern the crisis in each context of culture, Christianity, and the world which may occasion conversion.Kenneth Davis is working with the Hispanic team of the staff of the International Office of RENEW. He has recently been inducted into the Academy of Hispanic Catholic Theologians of the United States (AHCTUS).  相似文献

A short-term longitudinal study was conducted to determine whether self-regulation at 4 years could be predicted from child and maternal measures obtained when the children were age 24 months. The subjects were 69 children and their mothers drawn from the general community. Criterion behaviors assessed at 4 years were those suggestive of attention-deficit hyperactivity disorder. Of the 24-month child measures, maternal ratings of the child's impulsivity and attention span, plus an objective measure of delay ability, were the most effective predictors. Maternal negativity, as assessed in mother-child interaction, predicted the criterion behaviors, even after the child's behavior as an elicitor of maternal behavior was controlled. Maternal child-rearing attitudes on the dimensions of warmth and aggravation were also effective predictors, even after controlling for the child's emotionality as a possible determinant of maternal attitudes. It is argued that the results with the maternal attitude measures provide support for the hypothesis that maternal behavior is a contributor to the development of self-regulation.This research was supported by a State of Ohio Academic Challenge Grant to the Bowling Green State University Clinical Psychology Program, and by a Basic Grant awarded to the first author by the Bowling Green State University Faculty Research Committee. The authors are grateful to Eric Dubow, Douglas Ullman, and two anonymous reviewers for their helpful comments and criticisms on previous versions of this article.  相似文献
