加入水汽—温室效应后的Sellers模式

作者 沈金妹 《气象科学》 CSCD 北大核心 1989年第2期184-195,共12页

The study examined the forms of child labour practices common among market women and food sellers in Ife Central local government area of Osun State.It also determined the awareness level of market women and food sellers on the existing child labour law in Nigeria and finally examined factors contributing to child labour practices among market women and food sellers.The study employed the descriptive research of the survey type.The study population consisted of market women and food sellers in Ife Central local government in Osun State.The sample consisted of 170 market women and 80 food sellers in conveniently selected five markets in the study area.The researchers developed three research instruments for this study,namely:Knowledge of Child Labour Questionnaire(KCLQ),Forms of Child Labour Practices Questionnaire(FCLPQ),and Factors Contributing to Child Labour Questionnaire(FCCLQ).The three instruments were validated by the investigators,using Cronbach alpha which yielded 0.79,0.77,and 0.78 values for KCLQ,FCLPQ,and FCCLQ respectively.Data collected were analyzed by using simple percentage and Relative Importance Index.The results among others showed that domesticlabour ranked the first significantly influential forms of child labour practiced among market women and food sellers in Ife Central local government,Osun State with RII analysis of 0.810 and 0.850 respectively.The study therefore concluded that majority of the respondents have low awareness level on the existing child labour law hence government should intensify the creation of awareness of the child labour law among market women and food sellers in Ife Central local government,Osun State. 展开更多

Objective To provide reference for the relevant departments to train and manage online drug sellers.Methods A questionnaire was conducted among 124 grass-roots drug sellers from 13 online drug sales enterprises,including Tmall Medical Center and JD Home Health Channel and 265 teachers and students from 33 pharmaceutical colleges and universities.The problems were analyzed in this paper and some specific suggestions were made.Results and Conclusion 389 questionnaires were sent out and 371 effective questionnaires were recovered.The effective recovery rate was 95.37%.The universities surveyed mainly recruited undergraduates,accounting for 66.7%of the total.Most of the employees in the online drug sales enterprises surveyed graduated from secondary school or universities,accounting for 91.9%.The number of graduates surveyed who were willing to work in the online drug sales enterprises was low,accounting for only 8.67%.Besides,it was difficult for online drug sellers to be promoted,71.7%of the respondents had no promotion opportunities.In view of the main problems such as the low professional quality of online drug sellers,their low willingness to engage in online drug sales,and few promotion opportunities,it is suggested the reform of licensed pharmacists should be deepened to improve the number and quality of online drug sellers.Meanwhile,we should learn the advanced experience from developed countries.In addition,the income and welfare of the online drug sellers should be improved.Lastly,a unified management platform must be set up for online drug sellers by technical means. 展开更多

存在停售第三方卖家的复合型电商平台定价模型

数量众多的第三方卖家是一种战略资源,对复合型电商平台发展有重要意义。然而,观察发现:很多销量为零的第三方卖家(称之为停售第三方卖家)长期停留在复合型电商平台上。这些停售第三方卖家除了缴纳技术服务费外,无法给电商平台带来扣点... 数量众多的第三方卖家是一种战略资源,对复合型电商平台发展有重要意义。然而,观察发现:很多销量为零的第三方卖家(称之为停售第三方卖家)长期停留在复合型电商平台上。这些停售第三方卖家除了缴纳技术服务费外,无法给电商平台带来扣点收入,却会增加消费者筛选产品的成本,进而降低交易效率。基于这一现象,本文构建了一个包含停售第三方卖家的复合型电商平台模型,分析停售第三方卖家数量对均衡结果的影响,探讨他们对复合型电商平台的策略价值。研究发现:由于均衡解所处区域不同,停售第三方卖家的存在可能加剧也可能缓解平台自营和在售第三方卖家之间的竞争;与不存在停售第三方卖家情形相比,适当数量的停售第三方卖家可以同时提高复合型电商平台和在售第三方卖家的利润;控制第三方卖家总数量总是对在售第三方卖家有利,是否有利于复合型电商平台取决于单位交易成本获得的基本效用和技术服务费;当消费者更偏好平台自营时,在售第三方卖家利润会减少,复合型电商平台利润可能增加也可能减少。 展开更多

For many online businesses,online reviews are crucially important to managing reputation,word-of-mouth sales,and,ultimately,their survival.Hence,more and more on line business owners are posting public responses to both positive and negative reviews.But do these responses change anything?And,if so,which types of responses are the most effective for strengthening customer relationship and increasing the chances of repeat business?With two surveys and a series of partial least squares-structural equation modeling(PLS-SEM)analyses,we tested three releva nt hypotheses to an swer these questions.The results show that when busi ness replies to online reviews with promotional information,consumers perceive the seller to be self-interested,and both relati on ship quality and repurchase intenti on decrease.However,sincere responses that do not contain promotional information,such as gratitude and apology,are highly correlated to positive relationship quality and the likelihood of future repeat business.These findings enrich the academic literature on on line reviews,and the recommendations stemming from our results should be of interest to any business that relies on their online reputation for survival. 展开更多
