Using Contests to Provide Business Students Project‐Based Learning in Humanitarian Logistics: PSAid Example

Business students appreciate working on classroom projects that are both enjoyable and useful in preparing them for future careers. Promoting competition among project teams is also used as a method to motivate students. The Humanitarian Logistics Project (HLP) teaches undergraduate students the logistical implications of unsolicited material donations in disaster relief. To encourage competition, students are organized into teams of three and tasked with designing humanitarian public service announcements (PSAs) that improve their understanding of humanitarian issues in the general public. These announcements are then submitted to the national PSAid (Public Service Announcements for International Disasters) contest for American college students. The exercise is rigorous because it requires students to collect logistical data and use it to communicate the principle of smart compassion to the public in a creative fashion. Moreover, not only do students learn about topics related to humanitarian logistics by competing with other college students nation‐wide, but also do they make a socially responsible contribution to the public. Analysis of survey data shows that students’ learning outcomes from the HLP are significantly greater than those for other supply chain topics covered in class, and that student satisfaction with the HLP is high.     

Science Letters： Structure relationship of nitrochlorobenzene catalytic degradation process in water over palladium-iron bimetallic catalyst

Two isomers ofnitrochlorobenzene （o- andp-NCB） were treated by a Pd/Fe catalyst in aqueous solutions through catalytic amination and dechlorination. Nitrochlorobenzenes are rapidly converted to form chloroanilines （CAN） first through an amination process, and then rapidly dechlorinated to become aniline （AN） and CI^-, without the involvement of any other intermediate reaction products. The amination and dechlorination reaction are believed to take place predominantly on the surface site of the Pd/Fe catalysts. The dechlorination rate of the reductive degradation of the two isomers of nitrochlorobenzene （o-, and p-NCB） in the presence of Pd/Fe as a catalyst was measured experimentally. In all cases, the reaction rate constants were found to increase with the decrease in the Gibbs free energy （correlation with the activation energy） of NCBs formation; the activation energy of each dechlorination reaction was measured to be 95.83 and 77.05 kJ/mol, respectively for o- and p-NCB. The results demonstrated that p-NCBs were reduced more easily than o-NCBs.     

大学生户外运动休闲限制与参与行为的研究

对广东珠三角六所高校676名大学生进行调研,探索大学生参与户外运动休闲限制及其参与行为的关系。研究发现：休闲限制在大学生参与户外休闲运动的参与度、性别、年级、专业类型、均存在差异性;参与行为与休闲限制的四个维度呈负相关,其中自身限制与参与行为存在着非常显著的相互预测作用,而自身限制、人际限制、结构限制与户外休闲运动参加次数存在着非常显著的负相关,自身限制、结构限制作为户外休闲运动参加次数的预测指标有统计学意义。
