How to respond to journalists’ questions? A new perspective on Chinese premiers’ aggressiveness at press conferences (1993–2015)

This study extends the framework describing journalists’ aggressiveness at politicians’ press conference and develops five dimensions to measure politicians’ aggressiveness in response to journalists’ questions (initiative, directness, assertiveness, adversarialness, and accountability). Using the records from Chinese premiers’ press conferences (1993–2015), this research investigates five factors which might affect premiers’ aggressiveness: the administrative life cycle, economic conditions, journalists’ country of origin, the topic of questions, and number of questions. The results show that premiers exhibit less assertiveness during honeymoon periods and more assertiveness in other years. Premiers are more adversarial amid good economic growth but less adversarial during poor economic growth. They are more assertive and adversarial in response to questions related to politics and the military and less so in response to questions related to other areas. Premiers display more initiative and accountability toward journalists who ask more questions and less toward those who ask fewer questions. Premiers are more assertive and adversarial toward journalists from developed countries but less so toward those from developing countries. Over the past 23 years, premiers’ initiative, directness, and adversarialness have decreased while their accountability has gradually increased. The theoretical contributions of this research are discussed.

The industrial connections in Donald Judd's art

This paper examines the context and impact of the industrial materials and processes of the mid-twentieth century on Donald Judd's works, focusing on galvanized steel, cellulose nitrate paints, anodizing, and the RAL color matching system. Exploration of the industrial materials and methods Judd utilized provides a greater understanding of his processes, choices, and ultimately his art, its care, and legacy.     

朦胧诗以后:词与物

1985年以后,“朦胧诗人”逐渐引退,“朦胧诗”的单向度写作已经不再为更年轻诗人所满足。随着国人艺术观念的解放,诗歌写作风格也日趋多样。以时间为标志的“第三代”、“70后”、“中间代”、“80后”和以作品价值取向为标志的“知识分子写作”、“民间立场”、“下半身”等命名相继出现;各种写作潮流之间分野日益明显,并引发多次论争;民刊的日益兴盛与互联网的出现,使诗歌写作和发表打破了以前官办刊物的垄断地位。这一切,使近20年来的中国诗坛充满活力。     

智慧城市信息安全风险评估模型构建与实证研究

[目的/意义] 面对智慧城市日益突出的信息安全问题,提出一个科学的风险评估模型,以快速对智慧城市进行风险分类并分析风险因素。[方法/过程] 从智慧城市信息安全的5个层次和风险评估的4个主要因素出发,构建智慧城市信息安全风险指标框架,对智慧城市实例进行ward系统聚类形成分类属性,选择C4.5算法的决策树方法建立风险评估模型,并验证模型的科学性。[结果/结论] 结果发现:安全管理制度、数据泄露与损坏威胁、安全意识薄弱性和设备安全漏洞是智慧城市之间差距最显著的风险因素,根据评估结果提出保障智慧城市信息安全的建议。     

中国现代思想史上的"陶胡分歧"

陶行知与胡适的分歧贯穿了五四之后的近三十年中国现代思想史上的大事。二人之间的最初教育分歧不在教育观点本身,而是“教育界分歧”,始于1926年“庚款风波”;其次是30年代的政治9牾,基于两种基本爱国观的难于兼容,但非以政见分歧为主要内容;其三,双方主要的、根本的分歧是30年代形成的关于基本价值观——五四价值观的分歧。陶推崇一二九“大众”运动,反思并批判五四“小众”运动;由此出发,陶形成了自己的大众教育观,及总的大众价值体系,全面否定了新文化运动及胡在其中的历史地位。     

潮州产10种野菜中硝酸盐、亚硝酸盐及Vc的含量

利用分光光度法测定了潮州产10种野菜中硝酸盐、亚硝酸盐的含量，利用氧化还原滴定法测定了维生素ca含量．结果表明：月光花、决明、铁苋菜和叶下珠的硝酸盐含量低于轻度污染水平（432mg／kg鲜重），亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准（44．0mg／kg鲜重），它们属于一级野菜，可以安全食用；鸡矢藤、白勒和苎麻的硝酸盐含量低于785mg／kg，属于中度污染水平，亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准，属二级蔬菜范围，不宜生食，煮熟或盐渍可安全食用；鳢肠硝酸盐含量高于785mg／蚝而低于1440mg／kg，亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准，维生素C含量高于50mg／100g鲜重，属于三级蔬菜，不可生食和盐渍，可熟食。牡荆和肖梵天花虽然硝酸盐含量很低，但维生素C含量较低，亚硝酸盐含量高于无公害蔬菜亚硝酸盐含量的限量标准，所以不宜食用．     

略论新文学运动对诗性的轻慢及后果

新诗在将近一百年的发展中,没有能取得古典诗歌那样的成就,原因固然是多方面的,但新文学运动初期轻慢诗性肯定是重要原因。轻慢诗体,将诗与文、诗与(白)话等同,新诗文体一直受到合法性质疑;轻慢诗语,单纯强调语言的工具性,忽视语言的诗性,将诗歌语言与日常语言及口语等同,抛弃语言传统,导致新诗语言浅白,与几千年的诗歌传统脱节;轻慢诗情,或以科学之真否定艺术之情,或缺少节制,走向滥情,致使诗歌矫饰空洞。
