学术写作的互动式话语策略

学术写作并非完全机械化,也并非全盘避免作者主观情感的介入。学术作者使用多种话语策略来宣传其观点和立场,营造和谐对话空间,与读者形成良好互动,从而引导读者接受所述命题观点。基于学术语篇互动模型,分别从模糊语策略、作者身份构建方式以及作者与读者的隐性互动三个方面来阐释学术写作中的互动式话语策略。研究表明,每个学科都有其偏好的写作模式,教师应引导学生关注所属学科的语言范式,培养学生的读者意识,并在学术写作中采用积极有效、易于被读者接受的互动策略有力发声,推进研究。     

How Does Women’s Decision-Making Power Affect Budget Share,Nutrition and Education in Pakistan?

Understanding the effects of power distribution, particularly women’s decision making, on human development is important. This study used a set of direct measures of decision-making power from the Pakistan Social and Living Standard Measurement Survey and examined the relationship between women’s decision-making power and the food budget share, nutrition and child schooling. It found that in Pakistan, the relationship between women’s decision-making power and nutrition was not linear and varied depending on rural or urban residence. There was no clear evidence that higher women’s decision-making power would lead to better nutrition availability in Pakistan, but overall households were more likely to consume less grain and more vegetables. When women had higher decision-making power, children, particularly rural girls, were more likely to be enrolled in school.     

Understanding the Dynamics of the Individual Donor’s Trust Damage in the Philanthropic Sector

Although trust is long known to be critical to predict behaviors in a charitable context, little research has examined trust damage and its effects on giving behavior. Trust damage is an intermediate state between trust and distrust, rather than a simple reversal or extension, and can change over time. Our research explores individual donor’s trust damage through a dynamic evolution. Across the longitudinal survey, we conclude that the trust damage of pre-giving, giving, and post-giving stage plays different roles in the decision-making process. Trust damage does not play a direct role in the giving intention, but it can indirectly affect giving intention through its impact on perceived benefit and perceived risk. Individual donor’s satisfaction has a strong effect on post-giving trust or continual trust damage, which in turn positively affects future giving intention and behavior. Several important insights for practitioners in the nonprofit sector are also discussed.

Feature screening in ultrahigh-dimensional additive Cox model

The additive Cox model is flexible and powerful for modelling the dynamic changes of regression coefficients in the survival analysis. This paper is concerned with feature screening for the additive Cox model with ultrahigh-dimensional covariates. The proposed screening procedure can effectively identify active predictors. That is, with probability tending to one, the selected variable set includes the actual active predictors. In order to carry out the proposed procedure, we propose an effective algorithm and establish the ascent property of the proposed algorithm. We further prove that the proposed procedure possesses the sure screening property. Furthermore, we examine the finite sample performance of the proposed procedure via Monte Carlo simulations, and illustrate the proposed procedure by a real data example.     

京津冀服务业结构调整的动态研究

目前,中国区域经济,特别是东部地区呈现出"工业型经济"向"服务型经济"转型的趋势,且服务业内部结构也在发生显著变化,现代经济增长越来越依赖于服务业内部结构的升级。京津冀地区非常典型,故本文以京津冀区域一体化为依托,对京津冀服务业发展做Moore值分析,用2004—2013年的数据对北京、天津和河北服务业结构调整的程度和态势进行了比较研究,并详细分析了京津冀都市圈服务业发展路径和趋势,提出了相应的对策建议。     

论中日茶道文化的意境与精神气质

中日茶道文化是东方文化中的两朵奇葩,但是由于诸多原因,中日茶道文化在意境和精神气质上有着较大区别:中国的茶道仪式自然随和,圆润融通,日本的茶道仪式则过于拘于程序和礼节;中国将饮茶发展为日常生活艺术,日本则将饮茶变为俨然清规;中国茶文化是雅俗共赏的大众文化,日本茶文化则是高高在上的仪式文化。
