乳酸菌发酵给果蔬汁带来的风味变化及其适配性是影响品质的重要因素,用植物乳杆菌LP-115 400B分别发酵橙汁、苹果汁、梨汁、葡萄汁和青瓜汁,通过静态-顶空固相微萃取(headspace solid-phase microextraction,HS-SPME)和气质联用(gas chromatography-mass spectrometry,GC-MS)分析各果蔬汁发酵前后挥发性风味物质以及游离氨基酸、糖和酸等滋味物质的变化,并结合定量描述分析(quantitative descriptive analysis,QDA)方法进行感官评价,探索乳酸菌发酵对果蔬汁风味感官品质产生的影响和适配性问题。乳酸菌发酵代谢对不同果蔬汁风味影响差异较大。在发酵后的果蔬汁中,挥发性风味物质种类增加,其中醇酯类物质增加明显,有利于酯香型果汁果香和花香的突出(如苹果汁和梨汁);而醇香型青瓜汁的酒味、刺激性气味增加;萜烯类物质变化使得橙汁新鲜气息降低,发酵气味增强。果蔬汁中氨基酸变化显示出其与挥发性风味物质存在相互转换的关联性。发酵后当糖酸比适中时(梨汁21.00,苹果汁17.79),味感酸甜适度。

区域的中心—腹地关系一直是区域与城市发展领域关注的经典内容。全球化和信息化的推进产生了“流空间”和“中心流理论”,为现代城市间关系的研究提供了理论支撑,企业联系流反映的城市间关系受到学者的广泛关注,但多数研究聚焦在“整体空间”的城市网络特征表述,少有从特定问题出发,在更广阔的“非本地”范围研究中心城市与腹地的关系。论文基于1990—2018年县域尺度的企业流数据,研究北京与河北(本地)和京津冀区域外(非本地)的企业联系的时空格局和影响因素,从企业联系视角为北京与河北的经济落差提供解释,主要结论如下:(1)1990—2018年北京的本地性企业联系较弱,企业联系较强的县市主要集中在非本地,尤其是长三角等地区,非本地联系是北京企业联系的主要形式。从投资金额来看,北京与本地联系最强的行业为制造业,与非本地(主要是长三角)联系最强的行业为租赁和商务服务业;从建立分支数来看,北京与本地和非本地联系最强的行业都为金融业。(2)北京的本地企业联系主要受本地的经营环境(金融环境、政府干预、政策环境)和区位条件(地理邻近)的影响,非本地企业联系主要受关键资源(政治资源、科技投入)、经营环境(经济开放)和市场潜力(消费水平)的影响。河北综合承载力较弱、与首都产业链不协调和不匹配等问题给北京与之建立本地联系上带来了一定的阻力,使北京倾向于与具有更优越市场潜力和经营环境的城市建立跨区域的非本地联系。

自2016年7月12日海牙仲裁庭公布关于菲律宾提起的"南海仲裁案"的实体问题裁决以来,有关该仲裁案的相关报道吸引了世人的眼球。事实上,自2013年菲律宾阿基诺三世政府单方面向海牙仲裁庭提起仲裁以来,"南海问题"一直是国际舆论关注的焦点。本文从媒体外交视角分析了中国和菲律宾主要英文媒体《中国日报》和《菲律宾每日询问者报》对"南海仲裁案"的报道,通过框架分析发现,"双边协商"与"多边外交"之争,"不合法"与"约束力"之争归根结底可以纳入"新兴大国"与"守成大国"之争的范畴。而隐藏在媒体框架背后的是中菲两国在"南海问题"上的"对话"与"对抗"两种截然不同的态度。

本文首先从学理层面论证媒介化协商是媒体外交在解决国际争端中的具体应用;接着在实践层面,以美国和俄罗斯媒体就叙利亚化武事件展开的媒介化协商为例,从媒体框架互动、信源和隐喻三个方面讨论了两国媒体如何围绕核心议题展开互动与对话,推动该事件最后以采纳俄方抛出的议案为框架签署协议而告终。本文指出,框架互动分析呈现了美俄媒体展开媒介化协商的概貌,而两国媒体围绕核心隐喻进行的对话、讨论甚至辩论,构成了媒介化协商的支点,并贯穿于媒介化协商的整个过程,引用多元化信源不仅增强了俄方观点的公信力,还在观点的交叉论证中进一步论证俄方言论。
