The SCOR (Supply Chain Operations Reference) Model Supply Chain Classroom Simulation is an in‐class experiential learning activity that helps students develop a holistic understanding of the processes and challenges of supply chain management. The simulation has broader learning objectives than other supply chain related activities such as the Beer Game. Competing supply chains work to produce and sell two products, each experiencing differential demand. Seasonal demand, time delays, quality defects, and disruptions offer complexities that are part of actual supply chain management. The behavioral dynamics of collaboration between various functional nodes is illustrated through students’ interactions as they try to achieve their role's objectives. Through their decisions and actions, students develop a practical understanding of the processes and complexities of supply chain management. The classroom simulation actively engages students, and has been used successfully in multiple courses at the undergraduate and graduate levels at multiple universities and by a major corporation during a manager training session. Assessments indicate that the simulation is an effective experiential learning activity. While it offers learning outcome flexibility, common debrief themes are SCOR model processes, supply chain relationships, information flow, seasonal demand, quality defects, reverse logistics, and supply chain disruptions. 相似文献

Single-acting double-stator multi-pumps and multi-motors 总被引：4，自引：0，他引：4
We investigated a series of novel motors and pumps with a new structure called double-stator. Double-stator can be used as pump or motor just for the working condition on demand. A certain amount of pumps or motors are formed in one shell and these subpumps or submotors can work alone or in company without influence on other pumps or moters. This kind of double-stator pumps （motors） are called multi-pumps （multi-motors）. Through the analysis of multifarious connection modes of single-acting double-stator multi-pumps and multi-motors, the mathematical expressions of output flow rate, rotational speed and torque are acquired. The results indicate that different flow rates can be provided by one fixed displacement double-stator multi-pump system under the condition of an unalterable driven speed. Likewise, under the terms of a fixed input flow and without complex variable mechanisms, the functions of double speeds, multiple speeds and even differential connection can be realized by a double-stator multi-motor system with various output rotational speeds and torques. 相似文献

高中生高等教育需求的经济动因分析 总被引：4，自引：0，他引：4
本文通过估计高中生期望的高等教育回报率及其高等教育需求的影响,检验了人力资本理论的基本假设。研究表明,高中生对高等教育的市场回报率有比较准确的预期,他们的高等教育需求也受其期望的高等教育回报率的显著影响。个体的高等教育需求与人力资本理论的解释是一致的,即个体对高等教育的需求,受高等教育的经济回报所激励。 相似文献

This study focuses on the role of multiple solution tasks (MST) incorporating multiple learning tools and representation systems (MTRS) in encouraging each student to develop multiple perspectives on the learning concepts under study and creativity of thought. Specifically, two types of MST were used, namely tasks that allowed and demanded multiple solutions and tasks that allowed but did not demand multiple solutions from each student. Each of these tasks was tested in the field using 14-year-old students, through a comparative experiment on the learning of the mathematical notion of area within the C.AR.ME computer microworld that provides MTRS for the learning of area. Data analysis reveals that all students who were asked to encounter tasks allowing and demanding multiple solutions within C.AR.ME were motivated to invent a plethora of solution strategies to these tasks, by integrating both their intuitive and school-based knowledge with the knowledge embodied within C.AR.ME, and to construct diverse perspectives on the concepts in question which are non-common to paper-and-pencil and school practices. On the other hand, students expressed limited views on these concepts when faced with tasks that allowed but did not demand multiple solutions. 相似文献

近年来,在我国扩大内需、刺激消费等政策的刺激下,跨国零售巨头纷纷看好中国零售市场,并掀起了大规模的扩张浪潮,同时内资零售巨头也通过兼并、重组等方式进行扩张。零售业人才需求量由此不断增加。目前我国零售企业人力资源管理存在一些突出问题,如员工总体素质不高、流动率居高不下、企业不重视员工的培训等。解决这些问题,必须注重员工培训、合理规划人力资源、加强企业文化建设等。 相似文献

水力模型已广泛应用于给水管网设计、分析与运行中。在所有水力模型中,需水量是导致模型输出最不确定的参数之一。因用水情况不确定,使得管网中的节点需水量变得异常复杂。在大多数实际管网中,用于校核节点需水量的监测设备数量有限,且小于未知量个数,使得节点需水量校核作为欠定问题,令节点需水量校准产生较大误差,并且传统遗传算法校核节点需水量的方法是假定所有节点的需求乘数因子一致,这也导致校核后的模型无法接近真实运行情况,因此提出在欠定条件下用遗传算法解决需求乘数因子的校核问题。通过对一个实际案例多次运行并取平均值作为结果进行验证,结果表明,遗传算法的校核结果不仅能够与被测位置的实际值相拟合,而且可以得到非测量位置的管道流量和节点水头,其中校核后的节点水头和管道流量误差较小,平均误差分别为1.78%、4.05%。该方法相比于传统校核方法具有更高精度,且更能反映出管网真实运行情况,同时还避免了传统校核方法中因遗传算法产生局部最优解而导致误差偏大的问题,对于大型管网模型校核也具有一定参考价值。 相似文献

Opportunities to Learn in the Budapest Mathematics Classroom 总被引：1，自引：0，他引：1
Paul Andrews 《International Journal of Science and Mathematics Education》2003,1(2):201-225
This paper examines the nature of the problems posed, the processes by which their solutions were made public, their structural contribution to a lesson and the opportunities they offered for the learning of mathematics in Budapest, Hungary. The problems were derived from observations, the processes of which were informed by various comparative studies, of 94 mathematics lessons in the 10–14 age range. Problems, the analysis and categorisation of which were informed by the literature, tended to fall into two categories – single response with high levels of cognitive demand and multiple response with high levels of cognitive demand. Structurally lessons fell into a well practised pattern of classroom behaviour. They began with a public review of homework, comprising two or three multiple response problems which were solved collaboratively. This was followed by a warm-up period involving the oral setting and mental solving of a few single response problems. Lastly, the main body of the lesson involved several cycles in which a multiple response problem was posed, attempted individually before solutions were shared publicly. Lessons ended with homework being set. The discussion of the findings is framed by Hungary's variable performance on recent international tests of mathematical attainment. 相似文献

随着全面二孩政策的实施,婴幼儿托育服务需求日益增长。而当前我国学前教育的工作重心还是提升幼儿入园率,各类托育服务机构的发展和服务还远远无法满足家庭的托育需求。在分析各类托育模式发展面临状况的基础上,提出依托社区的家庭互助式托育模式,以解决当前托育服务的困境。家庭、社区及政府在该模式中扮演不同的角色,共同支撑家庭互助式托育模式,形成一个完整的托育系统。该模式具有互助性、便利性、可及性及自主性的鲜明特性。但依托社区的家庭互助式托育模式还需要从服务水平、质量监管、政策资金及服务宣传等方面拓展发展路径。 相似文献

Demand for private supplementary tutoring: conceptual considerations, and socio-economic patterns in Hong Kong 总被引：3，自引：0，他引：3
Despite the fact that in some parts of the world private supplementary tutoring is a huge industry with far-reaching economic, social and educational implications, the topic has been neglected by educational researchers. This paper focuses on the nature and determinants of demand for private supplementary tutoring. It first draws on literature from a wide range of countries to identify some conceptual considerations, and then presents data on socio-economic patterns of demand for tutoring in Hong Kong. It highlights the complexity of the topic, and calls for further detailed research in multiple settings. 相似文献

对民族大学学生进行多元文化教育既是理解我国多元一体民族文化构成的需要,也是民族大学学生“文化乡愁”和其文化身份重构的需要。在教育过程中要以培养学生全面的文化认知、多元的文化价值取向、自主的文化反思能力和跨文化交际能力为目标。为此应该把握好教育内容的选择策略、教师的教育策略和校园文化的建设策略。 相似文献

高校教师的满意度是指高校教师通过对工作相关状况的评估,而产生的主观感受和看法,它是由多个层面构成的复合概念。尽管因地区、院校层次、年龄、职称的不同,教师会对各自院校的满意度各有不同,但在工资待遇、学校管理、职称评定、进修机会、工作环境、人际关系等方面明显具有不满意因素的共性。学校要创造最好的福利待遇,满足教师基本物质条件的需要;营造良好的校园氛围,满足教师被尊重的需要;改革薪酬分配制度,满足不同人群的需要;建立科学的人才培养机制,满足职业发展的需要。 相似文献

当前人才市场需求的特点是通才型人才需求趋缓,"知识存量型"人才过剩;实践性、复合型人才紧缺;"求职难"与"求才难"的状况并存.在市场需求作用下,加强实践性和复合性教育是高等教育应对市场需求的根本出路.以市场需求为导向,宽容学生对知识的多重选择,培养个性化创新人才是高等教育自我完善的根本准则.推行双原制教育培养高端技能型人才则是毕业生应对就业难的新趋向. 相似文献

中国高等教育需求中的城乡差异-人力资本与社会资本理论的视角 总被引：6，自引：0，他引：6
本文应用人力资本和社会资本理论,探讨了中国高等教育需求中的城乡差异。研究表明:在控制其他因素以后,城乡高中生对高等教育有着同样强烈的需求,但学生的城乡背景与影响高等教育需求的人力资本和社会资本因素之间存在交互作用:(1)当高等教育预期收益率较低时,农村学生比城市学生更希望接受高等教育;当高等教育预期收益率较高时,城市学生比农村学生更希望接受高等教育。(2)当家庭网络资源较少时,农村学生比城市学生更希望接受高等教育;当家庭网络资源较多时,城市学生比农村学生更希望接受高等教育。农村低社会经济地位的学生对高等教育的旺盛需求表明,接受高等教育几乎是他们改变其不利社会地位、实现流动的惟一渠道。扩大农村学生的高等教育机会,是改善城乡差异的重要手段。政府应该在教育财政和招生等方面进行制度创新以回应此类教育需求。 相似文献
