The objective of this paper was to analyze the impact of online reviews on sales. Based on dual path model of commodity sales, an online reviews impact on the relationship between various factors, and then the theoretical hypothesis of each factor has been put forward in the model. As it is intuitive and strongly supported empirically, data including Chinese texts captured from Tmall.com was utilized, and then analyzed by SPSS and ROST CM6. Our empirical study on the reviews of Tmall.com indicated that the hypotheses are verified. 展开更多

The objective of this study is to compare the ranking of the quality of e-commerce B2C portals in Brazil according to explicit criteria described in the article with the ranking according to the INFO 100 ranking. Theoretical research is first described, followed by the construction of eight self-established criteria of B2C portal quality measures and identification and compilation of requirements used by the I-Best, Opinia, E-bit and other institutes. After that, a portal quality evaluation is made by the web site content analysis;finally, a comparison of the rankings is presented. The obtained results showed that in spite of the lack of knowledge of the criteria adopted by INFO100 [1], there could be agreement with the criteria adopted in this study, because there was agreement with the results for the Ponto Frio portal. Therefore, it was concluded that the eight criteria used in this study can be useful in a quality analysis of B2C electronic portals. 展开更多

This paper studies the impact of logistics cooperation in two competing companies,one of which is equipped with a self-run logistics system while the other is not.The latter outsources logistics services to a third-party logistics company before logistics cooperation,or to its competitor after logistics cooperation with the client's service quality being in proportion to and no greater than the service provider's service quality.We find that when the service provider is a price taker,logistics cooperation is beneficial to both firms only when the service quality after logistics cooperation is moderate.Interestingly,under some circumstances,the client's profit increases even when its service quality decreases after logistics cooperation because logistics cooperation eases the price competition.We also find that all-win situations in which logistics cooperation increases the firms7 profit,consumer surplus and social welfare can be achieved.Finally,when the service price can be chosen by the service provider,we propose a negotiation process in which agreement on logistics cooperation can be reached;when the firm can invest in service quality,logistics cooperation may lower the equilibrium investment level. 展开更多

As one of the most widely accepted adoption models in information systems research, the technology acceptance model (TAM) focuses exclusively on cognition-oriented constructs such as perceived usefulness and perceived ease of use. This perspective may have limited the explanatory power of TAM when it is utilized in studying consumers’ adoption intentions of online shopping. Based on the contrasts between e-commerce systems and traditional workplace information systems as well as empirical findings from a variety of recent e-commerce research works, this paper analyzes an extended model which integrates three additional constructs: trust, social presence, and perceived enjoyment. The interrelationship between these constructs is also explained. Empirical validations of this extended model are expected in future research. 展开更多

The whole e-commerce model is guided by the idea of the supply chain management from the perspective of the modern system, and the e-commerce integration model from customer to supplier is implemented, and the whole is optimized. E-commerce to cloud computing as the basic environment, the construction of public cloud services and private cloud resources, based on public cloud to the SaaS way to provide services to customers, focus on business search and business collaboration, make full use of the lnternet, modern communications technology to provide the real- service. The development of agricultural economy, no longer depends only on the number of some traditional agricultural resources, but also depends on the modern technology, information access and use. Through the development of basic network technology, by virtue of some modern electronic information technology and some other means that can improve the intelligence of agricultural use of the information resources, the proposed model provides the new methodology of the solution. 展开更多

目的 探讨可溶性生长刺激表达基因2蛋白(sST-2)、超敏C反应蛋白(hs-CRP)、N末端B型脑钠肽前体(NT-proBNP)、胰岛素样生长因子-1(IGF-1)水平与慢性心力衰竭(CHF)严重程度的关系。方法选取2023年1月—2024年6月山东大学齐鲁医院德州医院... 目的 探讨可溶性生长刺激表达基因2蛋白(sST-2)、超敏C反应蛋白(hs-CRP)、N末端B型脑钠肽前体(NT-proBNP)、胰岛素样生长因子-1(IGF-1)水平与慢性心力衰竭(CHF)严重程度的关系。方法选取2023年1月—2024年6月山东大学齐鲁医院德州医院收治的73例慢性心力衰竭患者为心衰组,选取该院同期健康体检者80例作为对照组。比较两组血清sST-2、hs-CRP、NT-proBNP、IGF-1水平。将心衰组按左室射血分数(LVEF)分为射血分数降低型(HFrEF)组、射血分数轻度降低型(HFmrEF)组、射血分数保留型(HFpEF)组,比较3个亚组患者血清sST-2、hs-CRP、NT-proBNP、IGF-1水平;采用多因素逐步Logistic回归分析心力衰竭的影响因素;Spearman相关性分析血清sST-2、hs-CRP、NT-proBNP水平与心力衰竭严重程度的相关性;绘制受试者工作特征(ROC)曲线分析血清sST-2、hs-CRP、NT-proBNP水平及三者联合对心力衰竭严重程度的诊断价值。结果 心衰组血清sST-2、hs-CRP、NT-proBNP水平均高于对照组(P <0.05),IGF-1低于对照组(P <0.05)。HFrEF组血清sST-2、hs-CRP、NT-proBNP水平均高于HFmrEF组和HFpEF组(P <0.05),HFmrEF组血清sST-2、hs-CRP、NT-proBNP水平均高于HFpEF组(P <0.05);3个亚组患者血清IGF-1水平比较,差异无统计学意义(P>0.05)。Spearman相关性分析结果显示,sST-2、hs-CRP、NT-proBNP水平与LVEF呈负相关(P <0.05),与LVEDD、LVEF分级均呈正相关(P <0.05)。多因素逐步Logistic回归分析结果显示:LVEF [O^R=0.679(95%CI:0.514,0.897)]为为心力衰竭严重程度的保护因素(P <0.05),LVEDD [O^R=1.224(95%CI:1.053,1.422)]、sST-2 [O^R=1.175(95%CI:1.007,1.372)]、hs-CRP [O^R=1.428(95%CI:1.021,1.998)]及NT-proBNP [O^R=1.001(95%CI:1.000,1.002)]均为心力衰竭严重程度的危险因素(P <0.05)。ROC曲线分析结果显示,sST-2、hs-CRP、NT-proBNP的曲线下面积分别为0.774、0.770、0.689,三者联合检测的曲线下面积为0.883,诊断价值高于任一单一指标。结论 血清sST-2、hs-CRP、NT-proBNP水平与慢性心力衰竭严重程度呈正相关,随心力衰竭严重程度增加而升高;sST-2、hs-CRP、NT-proBNP三者联合的诊断价值高于单一因素的诊断价值,诊断特异性高,可以为慢性心力衰竭严重程度的诊断提供新的思路。 展开更多

Objective To analyze the problems of pharmaceutical e-commerce and provide strategies for its development in the future B2C mode since drug network management has great potential in China.Methods By collecting,identifying,and conducting literature research,PEST-SWOT identification and positioning of pharmaceutical e-commerce in the B2C mode were carried out.Results and Conclusion A PEST-SWOT analysis matrix was established to analyze the status of B2C pharmaceutical e-commerce,and to summarize its advantages,disadvantages,opportunities and threats from four perspectives of politics,economy,society and technology.Suggestions on cultivating compound talents proficient in medicine and e-commerce,exploring online payment methods for medical insurance,integration of upstream and downstream of the industrial chain and data sharing are put forward to promote the healthy and long-term development of pharmaceutical e-commerce under the background of big data. 展开更多
