根据血压昼夜节律,观察给药时间对血压晨峰的影响。256例原发性高血压患者,经24h动态血压监测分为超杓型(n=49)、杓型(n=127)和非杓型(n=80)3组;各组再分为清晨服药组和晚上服药组。用药6周,比较用药前后血压昼夜节律及血压晨峰的变化,发现在改变血压昼夜节律及降低血压晨峰方面,超杓型组清晨服药优于晚上服药,非杓型组晚上服药优于清晨服药;杓型组清晨服药与晚上服药均能降低晨峰值,提示根据个体血压昼夜节律选择服药时间能更好地控制血压晨峰。 相似文献

This study examined quality of attachment to the mother and child-mother communication in adolescents' adjustment to the death of a father. Forty-eight Cambodian adolescents whose father had died within the previous 3 years completed a set of measures that included attachment, communication, grief, and self-esteem. Results showed that quality of attachment to the mother and whether the adolescent communicated with the mother about the father and found this to be helpful were positively related to adaptive grief and self-esteem. Moreover, support was shown for an indirect effect of quality of attachment to the mother on adaptive grief as mediated by communication. Implications of the findings for quality of attachment in adjustment to bereavement in a non-Western cultural context are discussed. 相似文献

Consumers often share word of mouth, and such interpersonal communication shapes attitudes and purchases. But while some research has examined what consumers talk about, there has been less attention to when consumers discuss. How does the distance from now (i.e., whether something is temporally near or far away) shape the likelihood of discussion? And might the effect of temporal distance on word of mouth vary based on whether those things happened in the past or will happen in the future? Five studies, including analyses of thousands of social media posts, address these questions. They suggest that consumers tend to talk about temporally near things, but that this is moderated by whether they are talking about the past or future (i.e., consumers talk about more temporally distant things when talking about the future). Accessibility seems to play an important role in these effects. While temporally near things tend to be more accessible, on average, goals and plans are more likely to remain active in the future, which shapes what gets discussed. These findings have implications for understanding drivers of word of mouth, how time shapes consumer behavior, and how companies can more effectively manage interpersonal communication. 相似文献

Five pigeons were given single-stimulus training on an 8-sec differential-reinforcement-of-low-rate schedule followed by steady-state generalization training using 12 wavelength stimuli. Three birds had a high percentage of reinforced responses on the training schedule and flat generalization gradients of total responses. The birds with fewer reinforced responses had much steeper generalization gradients. Generalization gradients plotted as a function of both stimulus wavelength and interresponse time showed that for most birds, stimulus control was restricted to responses with long interresponse times. Responses with very short interresponse times were not under stimulus control and there was some evidence of inhibitory control of short interresponse times. Interresponse-times-per-opportunity functions, plotted as a function of stimulus wavelength, showed that stimulus wavelength controlled the temporal distribution of responses, rather than the overall rate of response. The data indicate that the differential-reinforcement-of-low-rate schedule generates several response categories that are controlled in different ways by wavelength and time-correlated stimuli, and that averaging responses regardless of interresponse-time length obscures this control. 相似文献

Synchronistic mind‐matter correlations in therapeutic practice: a commentary on Connolly (2015) 下载免费PDF全文
This commentary adds some ideas and refinements to the inspiring discussion in a recent paper by Connolly ( 2015 ) that makes use of a dual‐aspect framework developed by us earlier. One key point is that exceptional experiences (of which synchronicities are a special case) cannot in general be identified with experiences of non‐categorial or acategorial mental states. In fact, most exceptional experiences reported in the literature are experiences of categorial states. Conversely, there are non‐categorial and acategorial states whose experience is not exceptional. Moreover, the psychodynamics of a synchronistic experience contain a subtle mesh of interacting processes pertaining to categorial, non‐categorial and acategorial domains. We outline how this mesh may be addressed in particular cases of synchronicity described by Connolly. 相似文献
