Isolating the geodemographic characterisation of retail format choice from the effects of spatial convenience

The authors analyze the relationship between the geodemographic profile of consumers and retail format choice while accounting for the effects of spatial convenience. The proposed analytic model assumes that format choice is an implicit portion of store choice, such that a geodemographic profile functions as a determinant of format choice, and spatial convenience is a determinant of store choice. The results show that some geodemographic dimensions capture preferences for certain store formats and thereby facilitate retailers’ selection of geographic markets. The results also indicate that obviating the effect of spatial convenience may lead to biased estimations.

Cultural Tourism And Flamenco In The City Of Cordoba (Spain)

Flamenco is a tourist product that can attract many visitors from around the world, and the city of Cordoba (Spain) has an important role in the origins of flamenco. This work studies whether the satisfaction of cultural tourists who visit the city can be influenced by cultural offers related to flamenco. To achieve this objective, fieldwork was carried out based on 709 surveys conducted in the most important flamenco “tablaos” (stages) of the city. The techniques of factorial analysis and linear adjustment were used. The results show that flamenco can be a product that complements the satisfaction of cultural tourists.

我国反倾销继发性保护问题的深层原因探析

从我国已立案的反倾销案件来看,我国发起的反倾销调查在化工行业存在明显的继发性保护问题,严重影响到下游企业和社会整体的利益,即产生了反倾销的公共利益问题。从化工行业的发展和公共利益角度的分析来看,继发性保护问题的实质是技术创新问题,其根本原因是我国相关企业的整体技术落后,自主创新能力不足。解决反倾销问题的关键是给予企业相应的激励机制,鼓励引进技术的吸收和自主创新。     

丙泊酚复合利多卡因静脉麻醉在高血压患者结肠镜检查中的应用

目的探讨丙泊酚复合利多卡因静脉麻醉在高血压患者结肠镜检查中的安全性及效果。方法回顾性分析47例高血压患者的结肠镜检查资料,将其分为常规组、无痛组。无痛组静脉缓慢注射丙泊酚和利多卡因混合液,使患者入睡后进镜检查。监测并记录两组在检查前、检查中、检查后的收缩压、舒张压、心率、血氧饱和度及镜检时间。无痛组记录麻醉诱导时间、苏醒时间、计算力及提问对答恢复正常时间。结果无痛组全部到达检查终点,常规组有2例未达到回盲部;无痛组镜检时间明显低于常规组,两组比较差异有统计学意义(P<0.05);无痛组的收缩压、舒张压、心率在检查中较检查前明显下降(P<0.05);常规组收缩压、舒张压、心率在检查中比检查前明显增高(P<0.05);两组检查结束后收缩压、舒张压、心率均恢复至检查前水平;血氧饱和度在两组的各个检查中无明显变化。无痛组麻醉诱导时间为(1.9±0.6)min、清醒时间为(6±5)min,计算力及提问对答恢复正常时间为(6±5)min。结论应用丙泊酚复合利多卡因静脉麻醉对高血压患者进行无痛结肠镜检查是可靠的。     

Board Structure and Intragroup Propping: Evidence from Family Business Groups in Hong Kong

Using earnings announcement events made by group member firms in Hong Kong, this study examines the governance role of boards of directors in curbing propping activities within family business groups. We find that earnings released by group member firms affect the stock prices of their nonannouncing group peers in a manner consistent with intragroup propping. More importantly, this effect is less pronounced when the announcing firms have a larger board or a board with a higher proportion of independent directors, but more pronounced when they have an executive director from their controlling families acting as board chairperson. Furthermore, the monitoring effect of boards of directors is strengthened for firms subject to new regulations increasing board power. Our results suggest that board oversight can mitigate propping activities.     

京津冀循环农业生态产业链的构建与思考
