Abstract： The source of design effect is defined as the manner in which the source information of a firm’s product design affects consumer product preferences and corporate attitudes. Currently, there are three major sources: professional designers, users, and AI, each exerts either positive or negative influences on consumer preferences through different psychological mechanisms. The source of professional design influences consumer preferences through the perceived competence of expert designers, whereas the source of user design influences consumer preferences through the perceived capabilities of users, empowerment and the psychological distance between users and brands. Furthermore, the source of AI design influences consumer preferences by virtue of the value and information offered by products designed using AI. It is noteworthy that, the source of design effect is moderated by consumer individual differences, product characteristics and the openness of a firm’s design policy. Future research should delve deeper into consumer reactions to mixed design sources as well as the psychological mechanisms and boundary conditions of the source of design effect.

Abstract：利用库姆塔格沙漠南北两侧洪积扇2017年6月至2018年5月的野外实测降水数据，对其降水特征进行了详细的分析，结果表明：（1）受地理位置、地形等的影响，库姆塔格沙漠降水空间分布差异较大。北侧北山洪积扇三垄沙地区的年降水量最小，为21.6 mm；南侧阿尔金山洪积扇降水量自西向东逐渐增多，胡杨沟上游、乌什喀特、赛马沟和多坝沟的年降水量分别为73.0、75.2、176.0 mm和137.4 mm；南侧阿尔金山洪积扇降水量大致自北向南逐渐增多，胡杨沟下游和中游年降水量分别为58.0 mm和56.4 mm，小于胡杨沟上游。（2）库姆塔格沙漠南北两侧洪积扇的降水主要发生在5—8月，累计降水量占到全年90 %左右。（3）库姆塔格沙漠南北两侧洪积扇年降水次数介于11~26次，数量较少的大降水事件对年总降水量贡献率大。

Abstract：高血压是卒中最重要的危险因素。我国目前高血压控制情况不佳，高血压知晓率、治疗率和控制率均较低。2017年，美国成人高血压预防、监测、评估和管理指南更新了高血压诊断标准,将高血压闽值定为130/80 mm Hg( 1 mm Hg=0. 133kPa)，并在该标准下制定了新的高血压治疗目标和管理策略。该指南主要基于收缩压干预实验( Systolic Blood Pressure Intervention Trial, SPRINT)研究结果，即与标准降压治疗相比，强化降压治疗可降低心血管事件发生率和全因死亡率。但同时，这一标准使高血压患者的数量大幅增加，且将影响大部分人群的治疗措施，包括老年人群和衰弱人群，在增加经济负担的同时增加了特殊人群的不良反应，不利于高血压防控和个体化治疗。故在此高血压标准下，结合现有证据，建议我国卒中预防策略尤其是一级预防应有所变化。

Abstract： Nowadays, many geo-distributed nearby edges have been deployed for providing high quality services to end users, which continuously produce large volume of user data. In order to minimize the average latency for a series of geo-distributed data analytical jobs, this paper first introduced online randomized algorithm ranTA. ranTA actually showed the preference on the task assignment under the consideration of both computing capacity of edges and the network bandwidth. Furthermore, in order to avoid overloading those edges with low computing capacities, this paper proposed data redistribution mechanism ranTA-data based on ranTA by redistributing some data to the central data center along with the tasks. The result of ranTA-data could be proved concentrated on its optimum with high probability. Extensive simulations show that ranTA-data gains nearly 30% improvement compared with current scheduling algorithms.
