国际疾病分类(ICD)是目前国际公认的卫生信息标准分类,但是由于我国的ICD分类工作开展的时间还不是很长,推广还不够广泛和深入,目前我国应用ICD分类还存在很多问题,ICD分类质量有待进一步提高和完善,加强临床医师的ICD分类知识培训和编码人员的专业培训及责任心教育是提高ICD分类质量的重要途径。 相似文献

In China, HIV shifts the lifestyle of not only parents living with HIV/AIDS, but also their children, partners, and extended
families. We examined factors related to the quality of life of parents living with HIV and the relation between family functioning
and individual quality of life. Interviews were conducted with a total of 116 parents living with HIV/AIDS. Analyses of variance,
Pearson correlations, and multiple regression analyses were performed to examine the relation between family functioning and
quality of life. We found a significant association between family functioning and individual quality of life for parents
living with HIV. In particular, family sociability had a strong relationship with the quality of life of parents living with
HIV. Parents living with HIV from families where both parents are HIV-positive reported a lower level of family sociability
than those from families with only one HIV-positive parent. HIV disclosure, family sociability, and number of children per
family were found to be significant predictors of overall quality of life for the population. Study findings underscore the
importance of developing interventions that improve family functioning for people living with HIV/AIDS in China. 相似文献

The same isochronous tone sequence was presented simultaneously to two mutually isolated subjects. In half the trials, accentuation in this sequence was accomplished by doubling the duration of the first and then of every fourth tone; in the other half, by doubling the frequency of those tones. The subjects’ task was to follow the rhythm of the resulting four-tone patterns by finger tapping to tone onsets. There were four auditory feedback (FB) conditions: (1) no FB; (2) FB from the subject’s own motor responses; (3) “alien” FB from the motor responses of the other pair member who, in turn, was listening to FB from his/her own tapping; (4) mutually “crossed” FB, where each pair member listened to FB from the tapping of the other. Tap onsets regularly preceded stimulus onsets. The observed order of the amount of this anticipation (from least to greatest) was: (1) own FB, (2) no FB, (3) alien FB, and (4) crossed FB. No mutual dynamic influence between simultaneously performing subjects was-detected. Anticipation was more pronounced for sequences that were accentuated by frequency rather than by duration changes. The type of accent also influenced timing of intertap intervals in the rhythmic patterns. For the frequency accent, regular timing was produced, whereas for the durational accent, shortening of the second and lengthening of the fourth (the last) intertap interval were observed. The presence and source of feedback as well as the character of accentuation are therefore relevant factors in the timing of auditorally controlled rhythmic motor behavior. 相似文献

This study explored the language experiences of dual language learners (DLL; n = 19) and English monolinguals (EM; n = 13) in preschool classrooms where English is the primary language of instruction and many home languages are present. Using the Language ENvironment Analysis™ system as a primary tool, we quantitatively analysed an average of 34 hours of recordings collected over 5–8 days for each participating child (Mage = 52 months) in six classrooms. Results showed that, during a typical preschool day, DLLs spoke as much as EMs but received less adult talk overall and had more 5-min segments with zero adult–child conversations than their EM peers. Follow-up analyses revealed that teachers generally talked less when children initiated the conversations than when adults initiated the conversations, and this pattern was particularly evident for DLLs. Study implications and future research are discussed. 相似文献

Roles of cognitive load and self-relevance during emotional information searching on decision-making
Older adults have been found to favor positive stimuli over negative stimuli; further, developing a negative preference may be a cognitively demanding process. In the present study, we focused on the joint effects task self-relevance and cognitive load have on older adults' emotional information preferences when performing decision-making. To examine this, we used multi-attribute decision tasks and process-tracing procedure to measure their searching process. The study composed of a 2 (age: young/old) × 2 (cognitive load: load/non-load) × 3 (attribute valence: positive/neutral/negative) × 3 (task self-relevance: high/medium/low) mixed design. Sixty-one young adults and 62 older adults viewed 5 (alternatives) × 5 (attributes) decision matrices that contained positive, negative, and neutral information, with the total views and mean time spent viewing each different valence (positive, negative, and neutral information) set as dependent variables. The results indicated that both young and old adults have no emotional information preference in regard to self-relevance. When under no cognitive load, both positive and negative information were viewed more than neutral information; however, under cognitive load, preference for negative information decreased; this effect size was more robust in older adults. There was also a main effect of self-relevance on total views and mean checking time, with attributes concerning higher self-relevance tasks being more likely to attract attention. Older adults exhibited a consistent hedonic focus, even in highly self-relevant contexts; however, this effect disappeared under cognitive load. Overall, the findings suggest that cognitive resources play an important role in emotional information processing during decision processes. 相似文献

Four studies compared the stock market decisions of Canadians and Chinese. In two studies using simple stock market trends, compared with Chinese, Canadians were more willing to sell and less willing to buy falling stock. But when the stock price was rising, the opposite occurred: Canadians were more willing to buy and less willing to sell. A third study showed that for complex stock price trends, Canadians were strongly influenced by the most recent price trends: they tended to predict that recent trends would continue and made selling decisions without considering the rest of the trend patterns; whereas the Chinese made reversal predictions for the dominant trends and made decisions that took both recent and early trends into consideration. Study 4 replicated the finding with experienced individual investors. These findings are consistent with the previous literature on different lay theories of change held by Chinese and North Americans. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献
