Two essays on mobile marketing
No full textConsumers’ dependence on mobile technology for their daily personal and business dealings has created many new business touchpoints, which in turn bring about novel opportunities for marketers to understand consumers’ behavior and identify ways in which more effective marketing strategies can be utilized. In two essays, this dissertation explores two domains in mobile marketing where new insights can be gained.
In the first essay, we leverage data collected from IoT sensors and combine with scanner transaction data to construct and estimate the entire offline conversion funnel for brick-and-mortar retail stores. We uncover the multi-stage effect of the marketing mix, and demonstrate the value of IoT data in enabling customized marketing strategies.
In the second essay, we examine what makes mobile marketing communications effective by studying the design elements of app push notifications. We construct a theory-based framework and separate out the treatment effects of proposed design elements using a causal inference machine learning method. Our findings provide guidance for marketing managers on design choice that improves the effectiveness of future push messages.Marketin

No full text企业信息技术接受的影响因素模型与实证研究：以智慧消防技术为例
No full textabstract: 消防工作是城市发展的基础保障。随着全国经济社会发展，高层建筑、大型商场等人员密集场所不断增多，消防安全监管的覆盖面越来越广、压力越来越大。高层建筑密集、消防基础设施不到位，火灾隐患多，单纯依靠人工巡检和传统方式监管，难以满足安全需求。
智慧消防将依托物联网、云计算、大数据、移动网等信息技术，与传统消防业务加大融合力度，构建一个立体式、覆盖全社会的火灾防控体系，这对于加大、加强消防部门的监督、管理手段和力度，提高各单位火灾预防能力，最大限度地保障社会和人民群众生命财产的安全具有十分重要和现实的意义。总体上来看，多数企业用户对于智慧消防的理解和参与程度不尽相同，导致目前关于智慧消防的认识还未统一，在具体执行层面相互之间也还没有达成共识，智慧消防在全社会的应用范围还处于初级和探索环节。
本文在相关文献综述的基础上，分别基于技术-组织-环境(TOE)框架和说服模型，通过回归分析对影响智慧消防技术接受意愿和购买行为的因素进行了理论分析和实证检验。相关结论可以为政府相关部门、社会企业等主体的日常决策提供参考和借鉴。
本文的研究结论主要有以下几点：（1）TOE框架对于分析企业是否采用智慧消防技术进而实现消防安全工作信息化、智能化升级具有一定的解释力，该框架下技术、组织和环境三个层面共计6个影响因素会对企业智慧消防技术的采用产生显著的正向作用，分别是技术维度的有用性、易用性、兼容性，组织维度的配套资源和风险偏好，以及环境维度的模仿压力。（2）技术的先进性、高管态度、政府压力没有通过显著性检验。（3）基于说服模型，本研究探索了影响企业购买智慧消防技术的考虑要素，企业的曝光率、知名度，营销团队的素养和专业话能力作为说服者特征，显著影响购买行为；企业接受智慧消防技术，自身经营状况作为说服对象特征，影响其的购买意愿；说服过程中提高技术的实用性证明有明显的促进购买效果。（4）本研究发现智慧消防企业规模并不足以显著影响购买行为，说服情境特征如说服场景和时间点也没有明显的作用。Dissertation/ThesisDoctoral Dissertation Business Administration 202
Simultaneous quantification of 6,7-di-hydroxyligustilide and gastrodin in rat plasma by LC-MS: application to pharmacokinetic study of tianshu capsule
No full textA LC-MS method was developed and validated for simultaneous determination of 6, 7-di-hydroxyligustilide and gastrodin in rat plasma, and which was subsequently applied in the pharmacokinetic analysis of an administration of a Chinese herbal extract containing Chuanxiong Rhizoma and Gastrodia Elata Rhizome, i.e. TianShu capsule against migraine. The analytes were separated on a Kromasil C18 column with a gradient elution program and detected without interference in the selected ion monitoring mode with positive electrospray ionization. The linear range was 0.010-10.0 μg/mL for 6,7-di-hydroxyligustilide and 0.025-25.0 μg/mL for gastrodin with the limit of quantitation of 0.01 and 0.025 μg/mL, respectively. The intra-day and inter-day precisions for the entire validation were less than14.7 % of RSD. The pharmacokinetic parameters indicated that 6, 7-di-hydroxyligustilide and gastrodin are absorbed rapidly and reached a maximum concentration within one hour, which was consistent with the clinical requirements for the rapid relieving the symptoms of migraine.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Word-of-Mouth System Implementation and Customer Conversion: A Randomized Field Experiment
No full textOnline retailers often face the decision on whether they should implement a word-of-mouth (WOM) system on their websites. Some retailers opt not to have an in-site WOM system (e.g., Tiffany.com and Tjmaxx.com ), whereas others implement and manage an internal WOM system (e.g., Amazon.com and Macys.com ). According to a new study in Information Systems Research, authors Ni Huang (Arizona State University), Tianshu Sun (University of Southern California), Peiyu Chen (Arizona State University), and Joseph M. Golden ( Collage.com ) conducted a randomized field experiment to examine how implementing an in-site WOM system from ground zero influences customer conversion in an online retailing website. Their results demonstrate that implementing an in-site WOM system can be a double-edged sword to the online retailing website. Specifically, the impact of a WOM system implementation on customer conversion is moderated by WOM volume, such that its effect is positive above a threshold of volume and negative below the threshold. Additionally, the researchers find that WOM valence reinforces the impact of a WOM system on customer conversion. These results offer important implications for the hundreds-of-billion-dollar online retailing industry on the implementation and management of online WOM systems.E-commerce firms often face the decision on whether they should implement a word-of-mouth (WOM) system on their websites. An in-site WOM system can potentially boost customer conversion by conveying signals and information about product popularity and quality. However, implementing such a system might also have unintended consequences, hindering product sales because of the lack of control over WOM volume and content. This study examines how implementing a WOM system (through social media integration) on an e-commerce website affects customer conversion in the two stages of the consumer purchase funnel, namely, adding a product to the cart and placing an order. Identifying the causal effect of WOM system implementation is challenging because e-commerce websites usually make their decisions based on private information about the potential impact of the system and may have simultaneously implemented other initiatives that could confound the effect. As a result, we conducted a randomized field experiment in collaboration with a large e-commerce website in the United States by testing two versions of a web page: one with a WOM system (treatment) and one without (control). We find that the impact of a WOM system implementation on customer conversion is moderated by WOM volume such that its effect is positive above a threshold of volume (measured by the number of comments) and negative below the threshold. Additionally, we find that WOM valence reinforces the impact of a WOM system on customer conversion. These results suggest that a social-learning mechanism is in play. Furthermore, our results show that the impact of a WOM system mostly occurs at the consideration stage in the upper purchase funnel (adding a product to the cart) rather than at the evaluation stage in the lower funnel (placing an order). Our study not only contributes to research on online system design but also offers practical implications for implementing and managing WOM systems on e-commerce websites
