学做服务工：中国都市青年、职业学校和新阶层的形成

中国职业学校学生的命运究竟如何？本文根据南京市两所职业学校为期一年（2007-2008年）的民族志研究,借由韦伯的分析路径,描述了职业学校学生学习生活以及最终由半技术工人进入新型服务经济领域的过程。研究表明,在今天的中国城市中,职业学校是一个产生新社会阶层的优选场所。首先,职业学校从结构和意识层面上生产一个独立的年轻人阶层群体;其次,职业学校打造的相似学生背景和共同生活空间有助于催生一种新的社会阶层和文化;再次,职业学校构建的新文化积极作用于学生的选择和生活方式,促使他们流向服务行业,成为半技术工人。总之,职业学校学生正处于一个新社会阶层初级阶段：共享着相似的生活方式、生活机遇、市场地位和有限的社会流动。     

A course in constructing effective displays of data for pharmaceutical research personnel

Interpreting data and communicating effectively through graphs and tables are requisite skills for statisticians and non‐statisticians in the pharmaceutical industry. However, the quality of visual displays of data in the medical and pharmaceutical literature and at scientific conferences is severely lacking. We describe an interactive, workshop‐driven, 2‐day short course that we constructed for pharmaceutical research personnel to learn these skills. The examples in the course and the workshop datasets source from our professional experiences, the scientific literature, and the mass media. During the course, the participants are exposed to and gain hands‐on experience with the principles of visual and graphical perception, design, and construction of both graphic and tabular displays of quantitative and qualitative information. After completing the course, with a critical eye, the participants are able to construct, revise, critique, and interpret graphic and tabular displays according to an extensive set of guidelines.

A course for clinical trial personnel in clinical study designs, randomization, allocation schedules, and interactive response systems

This continuing education course for professionals involved in all areas of clinical trials integrates concepts related to the role of randomization in the scientific process. The course includes two interactive lecture and discussion sections and a workshop practicum. The first interactive lecture introduces basic clinical trial issues and statistical principles such as bias, blinding, randomization, control groups, and the importance of formulating clear and discriminating clinical and statistical hypotheses. It then focuses on the most commonly used clinical study designs and the corresponding patient randomization schemes. The second interactive lecture focuses on the implementation of randomization of patients and drug supply through allocation and component ID schedules. The workshop practicum, conducted in small groups, enables students to apply the lecture concepts to real clinical studies. Flexibility was built into the workshop practicum materials to allow the course content to be customized to specific audiences, and the interactive lecture sessions can be stretched to cover more advanced topics according to class interest and time availability.

Teaching Introductory Statistics Courses So That Nonstatisticians Experience Statistical Reasoning

The most critical point in developing dynamic introductory statistics courses for nonstatisticians is deciding whether to teach statistical reasoning (concepts and thinking), statistical methods (computations), or both. Statistical reasoning should precede statistical methods. Workshop-based courses effectively provide situated learning and an intimate teaching environment. Use real (or realistic) data, graphics, and teach exploratory data analysis before classical methods. Evaluate the students' levels of statistical anxiety prior to and during the course.     

全球化背景下云南多样性民族文化的碰撞与发展

文化多样性对人类来讲就像生物多样性对维持生物平衡那样必不可少,它是人类持续和谐发展的根本保证.云南是一个多民族的边疆省份,民族的多样性决定了其文化的多样性.经济全球化的发展为云南各民族不同文化之间的交流和交融提供了新的历史机遇,同时也加剧了各民族文化之间的碰撞.在此背景下,我们必须努力做到"文化自觉",尊重文化个性,加强文化的调适,推进文化整合,这样才能实现保护、传承和发展云南民族文化多样性的目标.     

A MACROECONOMIC MODEL ON THE QUALITY OF GOVERNMENT AND ECONOMIC PERFORMANCE

We determine the relative rewards to producers, private rent‐seekers, and bureaucrats and allocation of talent between them in a general equilibrium model. Unproductive activity creates a negative externality on the relative rewards to producers. If the size of bureaucracy is exogenously given, among the multiple equilibria, the one with fewer private rent‐seekers yields higher welfare. By choosing a small size of bureaucracy, the government can establish the superior equilibrium as the unique outcome, which also achieves the constrained optimum. If the population of bureaucrats is endogenously determined, however, a larger bureaucracy enhances production and welfare. The size of government and economic performance are jointly determined, and their relationship depends on the quality of government. Our result supports the view that the size of government may not matter much; what is important is the quality of government. (JEL E60, E61, H00)     

课程文化的内涵分析

课程文化的实质,是课程文化最根本、最深层、最终极的规定性.以往的研究侧重从课程的角度或文化的角度来理解课程文化的内涵,应该说这是理解课程文化内涵的一种视角.本文从课程与文化两个概念的共同属性来把握课程文化的内涵.它是主体发展的文化资源.     

晚清数学的发展

晚清数学的发展主要是由技术进步的派生需求引导的,数学发展的目标与中体西用的要求之间存在冲突,这种矛盾最终导致中国数学的全盘西化。西学东渐改变了中算知识的结构却未能改变知识价值的结构,数学会通的效率受到考核技术的制约,考核技术的水平受到中体西用的制约。数学概念的进化因而受到阻碍,会通工作陷入效益递减的境地,最终导致中算被完全取代。     

试论美国内战期间林肯政府的外交政策

美国内战是美国历史上北方资本主义制度战胜南方奴隶制度的一场正义的、进步的战争。内战本属美国内部问题,但由于战争结局会影响到欧洲列强的既得利益,因而北方的林肯政府在内战中不得不面对当时极　　　　其复杂的国际关系。我们认为,北方之最终获胜固然在于其正义性,但林肯政府灵活、有效的外交策略,同样功不可没。本文将重点探讨美国内战的国际关系及林肯政府的外支政策。
