Involving constituents in agency priority setting: a case study

Many government agencies have "constituents" who believe the agencies should hear and consider their needs and desires in establishing program priorities. This article describes how one involves interested constituents (consumers, industry, medical professionals, and state organizations) in the agency's annual priority-setting process. This participation has produced a number of beneficial results-some expected and some unexpected.     

从语言学角度看《随园食单》菜品名称

江苏“随园菜”与北京“谭家菜”、山东“孔府菜”并称为中国最著名的三大官府菜,其中的“随园菜”得名于江苏历史名人,清代著名散文家、诗人袁枚的饮食文化著作《随园食单》。采用语言学的研究方法,分析《随园食单》中菜品名称的音节数目、组成结构、命名特点等,以挖掘江苏饮食文化的独特魅力。     

箪食瓢饮:河北涉县旱作梯田系统的饮食体系

作为中国重要农业文化遗产,河北涉县旱作梯田系统是当地居民积累生活经验、寻找生存之道,最终实现农业永续发展的智慧结晶。 本文以其核心区域王金庄村居民的日常饮食入手,意在描述梯田社会中食物从破土而出到送入口中的全过程,呈现当地在自然与文化共同作用下所形成的饮食结构和饮食习惯。 这种与自然相适应的文化模式以及由此而生的生态观念,形成了以藏粮于地、储粮于仓、节粮于口为主要内容的饮食体系,影响着当地人的行为选择,也发挥了重要的生态调节功能。     

An Empirical Test of a Neo-Malthusian Theory of Fertility Change

Some neo-Malthusians regard fertility as being kept in check by scarcities and constraints and, conversely, as being raised by economic prosperity. Since out-migration to developed countries and the receipt of food aid from developed countries relax the constraints imposed by a country’s carrying capacity, both will have a positive effect on fertility rates in developing countries. Moreover, better economic prospects will also raise fertility, all other things equal. This article provides an empirical test of these hypotheses derived from a neo-Malthusian theory of fertility change. The results fail to confirm the theory and often contradict it.

地区收入、食品价格与恩格尔系数

本文以2016年我国31个省级地区截面数据为样本,构建扩展模型考察恩格尔系数与收入、食品价格之间的关系。研究发现,恩格尔系数与地区收入存在显著的负相关性,纳入食品价格后收入对恩格尔系数的影响变得更为显著,二者关系满足恩格尔定律。恩格尔系数和以地区食品价格平价代表的食品价格之间显著正相关,若再考虑其他因素,则食品价格对恩格尔系数的影响会稍有减弱。进一步将食品区分为生活必需型食品与非生活必需型食品,测算得到的基本恩格尔系数、高阶恩格尔系数与收入之间仍呈负相关关系,但与基本恩格尔系数相比,高阶恩格尔系数与收入之间的负相关性更弱。恩格尔系数受生活必需型食品价格的影响强于非生活必需型食品价格的影响,基本恩格尔系数主要受生活必需型食品价格的影响,而高阶恩格尔系数同时受到两类食品价格的影响。     

Tea Art as Everyday Practice: Gongfu Tea in Chaoshan,Guangdong, Today

In recent decades a style of preparing and drinking tea modelled largely on gongfu tea associated with the Chaoshan region of north-eastern Guangdong Province, China, has been taken up as a contemporary tea art in Taiwan, Hong Kong, the Chinese mainland and elsewhere. This paper draws on fieldwork conducted in Chaoshan to examine gongfu tea as contemporary practice in its home setting. Three aspects are considered: gongfu tea as an everyday practice, as a refined practice, and as commercialised leisure in tea-houses. I argue that, as an everyday practice in Chaoshan, gongfu tea primarily serves to nourish social connectedness with family, friends and associates. It is regarded as an integral part of day-to-day life rather than a tea art. However, some people separate it from the everyday world by cultivating discernment and knowledge with regard to selected aspects, such as high-quality teapots or appreciation of different teas.

文化差异与文化导入对英语教学的影响

语言是交际工具。英语是学习科学知识,获取世界各方面信息与国际交往的重要交际工具。语言的运用能力反映出学习者对所学语言所代表文化的了解程度及自身文化程度高低的具体表现形式。通过对交际中错误现象的分析,可以证明语言教学中文化因素的重要性。同时,也可以证明中西方文化有生存环境、生活习俗、宗教信仰、英语词语运用等方面的差异。除此之外,文化是一种复杂的、多层次的,涉及到知识、信仰、艺术、道德、法律、风俗,也包括自然环境和生存的外部条件。因此,增加学生对文化概念的广泛理解和掌握,并通过文化导入,对文化内容作必要的取舍,才能揭示英语词语的文化内涵。
