应用皮肤光毒性实验仪进行化妆品皮肤光毒性试验的研究

[目的]探讨应用皮肤光毒性实验仪进行化妆品皮肤光毒性试验的试验条件和阳性对照物8-MOP的合适试验浓度。[方法]观测皮肤光毒性实验仪的UVA光强度与开机时间的关系,并根据测得的光强度平均值计算得出光毒性试验所需的照射时间;用不同浓度的8-MOP进行试验,排除8-MOP的原发性刺激作用,选择适宜的应用浓度进行皮肤光毒性试验;对两个防晒粉底按所选仪器条件进行试验。[结果]照射开始后2-100m in,UVA光强度稳定在4.3-4.4 mW/cm^2,平均值为4.4 mW/cm^2,故试验时的照射时间为38m in;用皮肤光毒性实验仪进行光毒性试验,0.05%8-MOP能引起豚鼠皮肤明显光毒性反应并且不引起原发性刺激反应;相同试验条件下未见两种防晒粉底引起豚鼠皮肤显著光毒性反应。[结论]用皮肤光毒性实验仪进行化妆品皮肤光毒性试验可行、有效。     

全球经济滞胀风险成因及前景

当前全球通胀压力不断加大,从欧盟的情况来看,由于减碳力度加大,碳价及能源价格暴涨正在推动电价飙升,多国PPI突破10%,创近30年之最;从美国情况来看,政策刺激力度超过次贷危机,短期内需求扩张推升了通胀;从生产要素看,疫情下的供应链中断叠加油气价格暴涨,各国都面临要素成本上升的问题;从不可控因素看,极端天气变化导致全球食品价格大幅上涨。在通胀压力与日俱增的同时,全球经济在短暂修复后出现放缓的趋势,呈现出滞胀的特征。为了避免经济滞胀向中长期演化,需要加强国际政策合作。     

An Empirical Analysis of Synthesizing the Effects of Festival Quality,Emotion, Festival Image and Festival Satisfaction on Festival Loyalty: A Case Study of Macau Food Festival

This study aims to examine the interrelationships among the festival quality dimensions, festival quality, emotion, festival image, festival satisfaction and festival loyalty. Analysis of data from 454 attendees in the 12^th Macau Food Festival indicates that the proposed model fits the data. The result of this study will assist festival management in developing and implementing market‐orientated service strategies to increase quality and image, and enhance the emotion and satisfaction of attendees in order to attain their loyalty toward food festivals.

Information effects of dividends: Evidence from the Hong Kong market

The literature has suggested that earnings and earnings forecasts provide stronger signals than dividends about future performance of a firm. We test the information effects of simultaneous announcement of earnings and dividends in the Hong Kong market, distinguished by three interesting features (concentrated family-shareholdings, low corporate transparency, and no tax on dividends). Our results show significant share price reactions to unexpected earnings and dividend changes, but dividends appear to play a dominant role over earnings in pricing, a result contrary to findings in the literature. The signaling hypothesis works primarily for firms with earning increases, while the maturity hypothesis works mainly for firms with earnings declines.

传统农区工业企业地理集聚及其用地空间响应——以河南省曲沟镇铁合金产业为例

集成多期遥感影像、企业经纬度坐标、深度访谈和统计年鉴等多维数据,综合运用遥感解译、缓冲区分析、核密度分析及土地利用转移矩阵等方法,研究了河南省曲沟镇1990年以来铁合金企业集聚与土地利用过程及特征。结果表明：(1)研究期内企业布局经历了“点状分散—带状集聚—网络布局”的演变过程;(2)镇域土地利用类型以农用地、工矿仓储用地及住宅用地为主,用地类型转换以工矿仓储用地显著增加和农用地大幅下降为主要特征;(3)镇域工矿仓储用地分布与企业集聚态势密切相关,空间扩展具有“接触式”、近农村居民点、高度集中于南部及大分散、小聚集等特征;(4)企业布局先后经历了“散点多核—‘丁’字形—‘不’字形—单核多圈”的演变过程,推动镇域空间结构实现发生期、成长期、稳固期和转型期的更替。     

Tariff and Quota Equivalence in Vertically Related Markets

This paper re‐examines the issue of tariff and quota equivalence by introducing an upstream market into the Hwang and Mai (1988 ) model, and then allowing the two downstream firms to cross‐haul within each other's market. We assume the upstream monopolist can select either a two‐part or a one‐part tariff pricing strategy. It is found that if the upstream firm adopts a two‐part (one‐part) tariff pricing strategy, then the market price of the final good under a tariff will be higher (lower) than that under an equivalent quota; that is, the quota is set at the import level under the tariff regime. This result stands in stark contrast to the prior findings of both Hwang and Mai (1988 ) and Fung (1989 ). Moreover, if the quota rent is set as being equal to the tariff revenue, the social welfare under a tariff will necessarily be lower than that under an equivalent quota.     

我国自愿环境协议的第三方主体选择及其职能安排刍议

自愿环境协议在环境管制的实务中得以流畅运用,政府与企业以外的第三方主体对企业环境绩效所进行的评估功不可没。在我国,可由政府对从事环境服务业的法人实体开展资质认证,依此判断这些组织机构是否具备为协助政府与企业实施自愿环境协议所必要的环境审计能力,并根据所获得的结论建立第三方协议参与者官方认证资源库。通过认证的第三方在自愿环境协议中负责对企业进行环境审计、环境目标执行计划书评审和履约绩效监督,企业购买此类环境服务的费用享受公共财政的支持。     

基于成本——效益分析的安徽农村生物沼气发展研究

生物沼气为生物质能源中最为普及的一种,由于其分散性、小型化和就地取材适合农村发展。文章运用成本——效益函数,通过将农村沼气发展具有代表性地区的实地调研情况与函数的理论前提进行对比分析后发现,发展大中型沼气项目更适合农村实际,从而提出下一阶段农村沼气的发展模式。
