【目的】 客观评估与分析我国中英文化学科技期刊在国内国际的影响力,并据此提出中国化学科技期刊现阶段发展的建议。【方法】 以中国16种SCI收录的化学期刊为样本,采用文献计量学方法分析其2011—2020年在JCR、CJCR、CSCD-JCR 3个数据库的定量指标,包括影响因子(Impact Factor,IF)、总被引频次(Total Cites,TC)、自(被)引率或他引率等。【结果】 JCR收录期刊的IF、 TC与自引率等数据反映出近10年来我国英文化学科技期刊国际影响力明显提升,中文科技期刊国际影响力略有提升。CJCR与CSCD-JCR收录期刊的相应指标反映出近10年来中文科技期刊在国内具有高影响力的优势在减弱,2016—2020年英文化学科技期刊国内影响力明显提升。【结论】 建议重视规划中文化学科技期刊的发展、优化现有英文化学科技期刊的结构以及新创办化学二级或交叉领域英文期刊以扩大该学科期刊方阵,促进我国中英文化学科技期刊全面深入的发展以及在国内国际的影响力大幅度提升。 相似文献

The COVID-19 outbreak started as pneumonia in December 2019 in Wuhan, China. The subsequent pandemic was declared as the sixth public health emergency of international concern on January 30, 2020, by the World Health Organization. Pakistan could be a potential hotspot for COVID-19 owing to its high population of 204.65 million and its struggling health care and economic systems. Pakistan was able to tackle the challenge with relatively mild repercussions. The present analysis has been conducted to highlight the situation of the disease in Pakistan in 2020 and the measures taken by various stakeholders coupled with support from the community to abate the risk of catastrophic spread of the virus. 相似文献

Living with a chronic or mental health condition can be challenging and requires considerable adjustment. As ways of coping are culturally influenced, it is important to understand how minority ethnic populations cope, to inform appropriate services. This review aimed to explore the coping strategies used by UK residents from an African Caribbean or Irish background between 1960 and 2020. A systematic literature search on strategies used to cope with chronic health conditions in both populations living in the United Kingdom identified 26 relevant studies. Data were extracted, quality of papers was appraised and critical interpretive synthesis was applied. Two major foci of the studies were coping strategies and barriers to coping. The main coping strategies were denial/scepticism, self-management, spirituality and religion. Within each population, there was variation in ways of coping. The review highlights the complex role of religion in influencing coping strategies. It demonstrates how personal and minority ethnic populations’ experiences of service use are connected with stigma, fear and mistrust, which also act as barriers to seeking help and to coping. Coping with a chronic or mental health condition in the Irish and African Caribbean populations is under-researched. Stigma, fear and mistrust in services act as key barriers to help-seeking and religion is a prominent coping strategy. However, few detailed examples were given on how it was used to assist individuals when managing a chronic or mental health condition. Also due to a lack of research, firm conclusions cannot be drawn for the Irish population. 相似文献

This study aimed to establish a new COVID-19 Fear (Higher Education) scale to investigate the relationship between fear and generalised anxiety symptoms among Chinese students in mainland China, Hong Kong, and other countries. 219 Chinese university students studying in universities in mainland China (n = 76, 34.7%), Hong Kong (n = 66, 30.1%), and overseas (i.e., outside of China as international students, n = 77, 35.2%) participated in an online study from March 31, 2020 to April 4. Participants completed a newly developed COVID-19 Fear (Higher Education) scale to measure three domains of fear including fear of infection, fear of instability and fear of insecurity related to the COVID-19 pandemic. They also completed the Generalized Anxiety Disorder 7-item scale (GAD-7) on the severity of anxiety symptoms. About 9.6% of the participants could be classified as exhibiting high anxiety level according to the GAD-7. More students studying overseas (about 15%) were classified into the high GAD group when compared to students studying in both mainland China (6.6%) and Hong Kong (6.1%). MANOVA results showed that students studying in Hong Kong and overseas had more concerns related to preventive measures related to COVID-19 than their mainland counterparts did. We concluded that international students studying away from their home country would have higher risk to develop anxiety problems during a collective trauma such as the COVID-19 pandemic. Education institutions should provide support services including online support groups, social media groups for mutual support to alleviate the fear and anxiety of international students. 相似文献

川乌与白芍配伍前后抗炎作用的比较研究 总被引:9,自引:0,他引:9
观察川乌与白芍配伍前后不同比例、剂量的抗炎作用。结果表明:乌、芍配伍前后对角叉菜胶和甲醛性大鼠足跖肿胀,棉球肉芽肿增生及小鼠二甲苯耳壳肿胀和腹腔毛细血管通透性增加均有不同程度的抑制作用,并使大鼠炎性组织释放的PGE2明显降低(P<0.05,P<0.01)。而且多数结果表明二药配伍的抗炎作用优于单味药川乌、白芍,其中尤其对慢性关节炎模型,有明显的协同增效作用(P<0.05,P<0.01)。 相似文献

Anticoagulant therapy after cardiac valve replacement was evaluated retrospectively in 1,200 patients attending 8 cardiac surgery clinics in the Tokyo area as part of the Tokyo Area Study on Anticoagulation After Cardiac Valve Replacement Using PT-INR (TAS). A prospective trial is also in progress and will be reported later. The prothrombin time international normalized ratio (PT-INR) was determined at the time of thromboembolic and bleeding complications in 1,200 patients. During the 5 year study period, thromboembolisms occurred in 21 patients, and bleeding complications occurred in 15 patients. In 71% of patients with thromboembolism and 47% of those with bleeding complications, the PT-INR was within the range of 1.6 to 2.8, which is the accepted therapeutic range in Japan. Therefore, the correct PT-INR therapeutic range for Japanese patients with mechanical heart valves needs to be reexamined, and data from the prospective TAS trial that is currently underway will be used for this purpose. 相似文献

The objective of the study was to translate and adapt the SF-36 Health Survey for use in Tanzania and to test the psychometric properties of the Kiswahili SF-36. A cross-sectional study was conducted as part of a household survey of a representative sample of the adult population of Dar es Salaam, Tanzania. The IQOLA method of forward and backward translation was used to translate the SF-36 into Kiswahili. The translated questionnaire was administered by trained interviewers to 3,802 adults (50% women, mean (SD) age 31 (13) years, 50% married and 60% with primary education). Data quality and psychometric assumptions underlying the scoring of the eight SF-36 scales were evaluated for the entire sample and separately for the least educated subgroup (n=402), using multitrait scaling analysis. Forward and backward translation procedures resulted in a Kiswahili SF-36 that was considered conceptually equivalent to the US English SF-36. Data quality was excellent: only 1.2% of respondents were excluded because they answered less than half of the items for one or more scales; ninety percent of respondents answered mutually exclusive items consistently. Median item–scale correlations across the eight scales ranged from 0.47 to 0.81 for the entire sample. Median scaling success rates were 100% (range 87.5–100.0). The median internal consistency reliability of the eight scales for the entire sample was 0.81 (range 0.70–0.92). Floor effects were low and ceiling effects were high on five of the eight scales. Results for n=402 people without formal education did not differ substantially from those of the entire sample. The results of data quality and psychometric tests support the scoring of the eight scales using standard scoring algorithms. The Kiswahili translation of the SF-36 may be useful in estimating the health of people in Dar es Salaam. Evidence for the validity of the SF-36 for use in Tanzania needs to be accumulated. 相似文献
