胡椒提取物在内酯豆腐保鲜中应用

采用L933正交试验优化胡椒内酯豆腐工艺条件为:大豆与水比例1∶4,GDL添加量0.20%,胡椒粗提取物添加量25 mg/L豆浆.胡椒内酯豆腐和普通内酯豆腐的细菌总数测定结果表明,在3 h-6 h内细菌总数无较大变化,9 h后有明显变化,随时间推移细菌总数呈递增趋势.通过24 h内细菌总数变化,可看出在24 h内,胡椒内酯豆腐细菌总数总体小于普通内酯豆腐的细菌总数.     

戴名世与清前期文化政策

戴名世因 《南山集》 案彰显悲情的一生. 其实, 探究戴名世的字号、 文章及交游发现: 此案发生的必然性在于, 戴氏作为士人的一个代表存在着对朝廷的认同问题, 而这在清统治者看来是不可容忍的. 康熙帝处理此案采取了高压与怀柔并用的手段, 这并不违背 "稽古右文" 以集大成的文化政策. 历经此案劫后, 清代士人群体特别是桐城籍士人, 及时调整了与当朝的关系, 消解夷夏之别的文化隔阂, 彰显古文经世致用的现实功能, 不仅使大部分士人割断了与前朝的联系, 而且也促使桐城派的产生, 进而"北方之强" 与 "南方之强" 在有清一代中奏出具有总结和整理特色的文化强音. 戴名世作为使桐城籍士人以古文与当朝建立的关系转折性的人物, 显然, 研究桐城派不可绕过戴名世, 更不能忽视清前期的文化政策.     

排他管辖权条款对中国中小货主的影响及对策

针对管辖权条款是否具有排他效力这一问题,海事理论与实务中一直持否定的态度。通过比较联合国《鹿特丹规则》有关选择法院协议（管辖权条款）在批量合同的当事人之间具有排他效力,在符合特定条件下对第三人也具有排他效力之规定,探讨其规定可能给中国这样一个FOB贸易出口大国的众多中小货主带来的被动局面,并从理论上提出应对策略。     

A rejoinder to "The impact of infectious diseases on remittances inflows to India"

We argue that the volume of remittances sent home by migrants is influenced by the exogenous likelihood that the duration of their migration will be cut short. A higher probability of reverse migration, brought about by the collapse of jobs in the wake of COVID-19, made migrants attach greater importance to the creation of a social and economic environment in their places of origin that can support them when they return. There are several ways in which this can be done. One is by instilling gratitude. When bigger remittances are responded to by greater gratitude, the support will be bigger. An impact of the COVID-19 pandemic on migrants’ perceived duration of their migration is an increase in the uncertainty of the duration. The good will of migrants’ families and communities at origin is a form of insurance. A standard response to uncertainty is to take out insurance, and when uncertainty is higher, insurance is more valuable, and there is a tendency to acquire more of it. As it happens, the link between the volume of remittances and the likelihood of return migration does not feature at all in Shastri’s (2022) paper, nor for that matter in related writings by the World Bank and the IMF. The purpose of this rejoinder is to draw attention to this link, inducing students of migrants’ remittances to explore the link.     

Liquidity in Asset Markets With Search Frictions

We develop a search‐theoretic model of financial intermediation in an over‐the‐counter market and study how trading frictions affect the distribution of asset holdings and standard measures of liquidity. A distinctive feature of our theory is that it allows for unrestricted asset holdings, so market participants can accommodate trading frictions by adjusting their asset positions. We show that these individual responses of asset demands constitute a fundamental feature of illiquid markets: they are a key determinant of trade volume, bid–ask spreads, and trading delays—the dimensions of market liquidity that search‐based theories seek to explain.
