Immigrant Asian youth's five cultural-identity stages and their challenges are examined. Theological significance in working with immigrant Asian youth is also the focus of this article. The essay concludes with implications for pastoral counseling practice, with respect to culturally sensitive effective therapeutic treatment of immigrant Asian youth and their families. 相似文献

One-trial Pavlovian conditioning has been demonstrated with aversive reinforcers such as electric shock and lithium chloride. The present experiments using male Japanese quail were conducted to determine if an appetitive unconditioned stimulus (US), the opportunity to copulate with a female quail, can also generate one-trial learning. In Experiment 1, subjects were exposed to a contextual conditioned stimulus (CS) for 35 sec and then given copulatory opportunity. In Experiment 2, male birds were given 0, 2, or 4 min of exposure to the contextual CS before presentation of a female. In both cases, control groups received comparable exposure to both the contextual CS and the sexual US, but in an unpaired fashion. Subjects were tested for sexual learning by reintroducing them to the experimental context in the presence of a test object that incorporated the taxidermically prepared head of a female quail. In both Experiments 1 and 2, subjects for whom the contextual CS and sexual US had been paired displayed significantly more approach to the test object than did unpaired subjects. 相似文献

"Silent" metaplasticity of the late phase of long-term potentiation requires protein phosphatases 下载免费PDF全文
The late phase of long-term potentiation (L-LTP) is correlated with some types of long-term memory, but the mechanisms by which L-LTP is modulated by prior synaptic activity are undefined. Activation of protein phosphatases by low-frequency stimulation (LFS) given before induction of L-LTP may significantly modify L-LTP. Using cellular electrophysiological recording methods in mouse hippocampal slices, we show that LFS given before induction of L-LTP inhibited L-LTP in an activity-dependent manner without affecting either basal synaptic strength or the early phase of LTP (E-LTP). This anterograde inhibitory effect of LFS was persistent, required N-methyl-D-aspartate (NMDA) receptor activation, and was blocked by inhibitors of protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A). These data indicate that certain patterns of LFS can activate PP1 and/or PP2A, and that long-lasting activation of these phosphatases by prior LFS can suppress the subsequent expression of L-LTP without affecting E-LTP. Because this inhibition of L-LTP is caused by prior synaptic activity that, alone, produced no net effect on synaptic efficacy, we suggest that this is a “silent” form of metaplasticity that may influence long-term information storage by modulating the capacity of synapses to express L-LTP after repeated bouts of activity. 相似文献

This study reports results from a meta-analysis of 28 correlates of pay level satisfaction involving 240 samples from 203 studies conducted over the past 35 years. Results are presented in 4 categories: primary determinants, antecedents, correlates, and outcomes of pay satisfaction. The authors controlled for pay in examining relations between correlates and pay level satisfaction, as suggested by theory and when primary studies were available to do so. The authors found support for many of the relations suggested by a theoretical model and also note some limitations in the research that has tested this model. The authors recommend changes and additions to the model and suggest additional primary research in specific areas. 相似文献

In this paper, semi-Post algebras are introduced and investigated. The generalized Post algebras are subcases of semi-Post algebras. The so called primitive Post constants constitute an arbitrary partially ordered set, not necessarily connected as in the case of the generalized Post algebras examined in [3]. By this generalization, semi-Post products can be defined. It is also shown that the class of all semi-Post algebras is closed under these products and that every semi-Post algebra is a semi-Post product of some generalized Post algebras. 相似文献

This study examines the impact of informal social support from family and friends on the well-being of older African Americans. Analyses are based on a nationally representative sample of older African Americans from the National Survey of American Life (n = 837). Three measures of well-being are examined: life satisfaction, happiness and self-esteem. The social support variables include frequency of contact with family and friends, subjective closeness with family and friends, and negative interactions with family. Results indicate that family contact is positively correlated with life satisfaction. Subjective closeness with family is associated with life satisfaction and happiness and both subjective closeness with friends and negative interaction with family are associated with happiness and self-esteem. There are also significant interactions between family closeness and family contact for life satisfaction, as well as friendship closeness and negative interaction with family for happiness. Overall, our study finds that family and friend relationships make unique contributions to the well-being of older African Americans. Qualitative aspects of family and friend support networks (i.e., subjective closeness, negative interactions) are more important than are structural aspects (i.e., frequency of contact). Our analysis verify that relationships with family members can both enhance and be detrimental to well-being. The findings are discussed in relation to prior research on social support and negative interaction and their unique associations with well-being among older African Americans. 相似文献
