季铵盐催化氧化制备苯甲酸的研究

在甲苯氧化制备苯甲酸的实验中,利用季铵盐氯化苄基三乙铵(TEBA)作为相转移催化剂,KM-nO4作为氧化剂.考察了TEBA用量、高锰酸钾用量、反应温度、反应时间对反应的影响.得出最佳反应条件:反应温度为90℃,反应时间2小时,KMnO4与甲苯的摩尔比为2.5∶1,季铵盐TEBA与甲苯的摩尔比为1∶10时,产率达72.1%.     

语音合成中的文本归一化问题

文本归一化是语音合成中一个与语言规划联系最为密切的问题。英语文本归一化的3个任务是：句子的词例还原,非标准词的处理,同形异义词的排歧。根据汉语语音合成的实际,汉语文本归一化应当解决的问题是：汉语文本的词例还原,汉语文本非标准词的处理,汉语文本同形异义词的排歧。此外,还应注意汉语语音合成中特殊韵律现象的处理。     

COMBINING INDIVIDUAL PARTICIPANT DATA AND SUMMARY STATISTICS FROM BOTH CONTINUOUSLY VALUED AND BINARY VARIABLES TO ESTIMATE REGRESSION PARAMETERS

Recent research has extended standard methods for meta‐analysis to more general forms of evidence synthesis, where the aim is to combine different data types or data summaries that contain information about functions of multiple parameters to make inferences about the parameters of interest. We consider one such scenario in which the goal is to make inferences about the association between a primary binary exposure and continuously valued outcome in the context of several confounding exposures, and where the data are available in various different forms: individual participant data (IPD) with repeated measures, sample means that have been aggregated over strata, and binary data generated by thresholding the underlying continuously valued outcome measure. We show that an estimator of the population mean of a continuously valued outcome can be constructed using binary threshold data provided that a separate estimate of the outcome standard deviation is available. The results of a simulation study show that this estimator has negligible bias but is less efficient than the sample mean – the minimum variance ratio is based on a Taylor series expansion. Combining this estimator with sample means and IPD from different sources (such as a series of published studies) using both linear and probit regression does, however, improve the precision of estimation considerably by incorporating data that would otherwise have been excluded for being in the wrong format. We apply these methods to investigate the association between the G277S mutation in the transferrin gene and serum ferritin (iron) levels separately in pre‐ and post‐menopausal women based on data from three published studies.

结构方程模型在系统综合评估指数中的应用

文章提出采用结构方程模型建立多指标系统评估指数模型。该方法可以方便地研究每一个隐变量与其显变量集合之间的关系,并且可以分析各隐变量与综合评估指数之间的联系,得到一个既能综合各隐变量、又能很好地代表系统中所有指标变量的综合指数。论文以中国城市发展水平评估为例,采用了反映经济水平和生活水平的两个变量组,将结构方程模型用于建立城市综合评估指数,对不同城市进行综合评价排名,得到的结果与一般的经济地理知识十分吻合,验证了模型的有效性。     

“中国模式”的文化解读

正如民族精神在历史上成为中华民族不竭生命力的重要源头,在当代中国,以自强不息、厚德载物和与时偕行为形上内核的中华民族精神,为中国模式不断克服艰难险阻、焕发出新的生机与活力提供了不竭的精神动力。以植根于中国文化注重综合的思维方式,中国模式体现出了根据自身发展的实际需要,既以开放的心态直面外来经验,又能以我为主地加以选择和消化,兼收并蓄、融合会通的基本特色。立足于中国文化崇尚和谐的价值取向,在处理自我与他者关系的基本价值取向上,中国模式把谋求互相间的合作放在了首位,而不同于追求制衡的西方模式。中国文化构成了中国模式重要的思想底蕴。

Children's experiences and needs in relation to domestic and family violence: Findings from a meta‐synthesis

Domestic and family violence is a significant issue experienced by many children that can have severe detrimental impacts to their health, development, and well‐being. Despite the significance of this issue, it is only recently that children have been included in research that seeks to understand the impacts that domestic and family violence may have on their lives. This paper reports on the findings of a meta‐synthesis, which explored qualitative research about children's experiences of domestic and family violence. Thirty‐two studies, including from the United Kingdom, North America, and Australia were included for review. The meta‐synthesis found that children describe domestic violence as being a complex, isolating, and enduring experience that often results in disruption, losses, and challenges to their significant relationships. Children's common feelings of fear, worry, powerlessness, and sadness were also uncovered, in addition to the strategies they employed to try and facilitate the safety and emotional well‐being of themselves and their family. Children's wants and needs are also highlighted. The findings demonstrate that despite the increasing interest in children's experiences of domestic and family violence, qualitative research remains limited, with many gaps evident. Implications for research, policy, and practice are considered.     

Reflections on experiential learning in evaluation capacity building with a community organization,Dancing With Parkinson’s

This paper discusses what was learned about evaluation capacity building with community organizations who deliver services to individuals with neurological disorders. Evaluation specialists engaged by the Ontario Brain Institute Evaluation Support Program were paired with community organizations, such as Dancing With Parkinson’s. Some of the learning included: relationship building is key for this model of capacity building; community organizations often have had negative experiences with evaluation and the idea that evaluations can be friendly tools in implementing meaningful programs is one key mechanism by which such an initiative can work; community organizations often need evaluation most to be able to demonstrate their value; a strength of this initiative was that the focus was not just on creating products but mostly on developing a learning process in which capacities would remain; evaluation tools and skills that organizations found useful were developing a theory of change and the concept of heterogeneous mechanisms (informed by a realist evaluation lens).
