Flexible‐Duration Extended Warranties with Dynamic Reliability Learning

Frequent technological innovations and price declines adversely affect sales of extended warranties (EWs) as product replacement upon failure becomes an increasingly attractive alternative. To increase sales and profitability, we propose offering flexible‐duration EWs. These warranties can appeal to customers who are uncertain about how long they will keep the product as well as to customers who are uncertain about the product's reliability. Flexibility may be added to existing services in the form of monthly billing with month‐by‐month commitments or by making existing warranties easier to cancel with pro‐rated refunds. This paper studies flexible warranties from perspectives of both customers and the provider under customers' reliability learning. We present a model of customers' optimal coverage decisions and show that customers' optimal coverage policy has a threshold structure under some mild conditions. We further show that flexible warranties can result in higher profits and higher attach rates in a homogeneous market as well as in a heterogeneous market with multiple segments differing in various dimensions.     

Large Robust Games

With many semi‐anonymous players, the equilibria of simultaneous‐move games are extensively robust. This means that the equilibria survive even if the simultaneous‐play assumption is relaxed to allow for a large variety of extensive modifications. Such modifications include sequential play with partial and differential revelation of information, commitments, multiple revisions of choices, cheap talk announcements, and more.     

“2000后”学前教育专业大学生的合作倾向调查研究

合作是幼儿教师必须具备的职业素养。为了解我国当代学前教育专业大学生的合作倾向特征,本研究采用问卷调查与访谈法,对我国某高校学前教育专业的358名在校大学生展开调查。研究发现,首先,学前教育专业大学生整体上具有较为良好的合作倾向。其次,独生/非独生子女家庭、城市/乡镇生源地的学前教育专业大学生不存在合作倾向的显著性差异,而不同年级学前教育专业大学生之间存在合作倾向的显著性差异。第三,与物理与电子信息工程专业的大学生相比,学前教育专业大学生的合作倾向还存在一定的可提升空间。访谈研究表明,合作化、游戏化的教学形式有助于提升学前专业大学生的合作倾向。     

Tensions between (Post)Bureaucratic and Neo-normative Demands: Investigating Employees’ Subjective Positions at EurAirport

The introduction of a neo-normative discourse in a (post)bureaucratic organization can result in tensions between the neo-normative injunction to be authentic and exhortations to fit with the ideal (post)bureaucratic organizational subject. Focusing on how shopfloor workers subjectively experience the tensions between neo-normative and (post)bureaucratic demands, this empirical investigation yielded three major contributions. First, it pinpointed and addressed significant gaps in existing studies of normative and neo-normative discourse. Second, the study better distinguished normative and neo-normative control on the basis of two tensions: (1) authenticity versus conformity; and (2) conflation versus differentiation between life and work. Third, the study identified four distinct subject positions that demonstrated how organizational participants creatively appropriate and strive to resolve these two tensions in a work setting that mixes normative and neo-normative control.

传统邮驿体系的时—空结构与清帝国权力网络——从《大清会典》驿程看清代通讯手段的时效困境

清帝国依托庞大的邮驿体系，建构了从中央到地方垂直的帝国权力网络。集权国家需要克服距离越远对地方控制越难的问题，因而在长期保持对里程信息收集整理、补充校正与记录存储的传统，驿程的记录与实际运行与之互为表里。《大清会典》及《则例》中的驿程信息主要有三类：节点(包括原点)、路线和数据，其记载有着复杂而又一以贯之的结构与模式，用“链条状”和“树状”两种方式呈现了驿路的分布结构，其向心性和层级性表达了古代王朝国家中央顶层设计“中心—边缘”的地理格局、空间秩序与特定的政治思维。道路里程信息既是日常邮驿工作开展的实用资料，也是国家持续掌握交通权力的知识来源。由于交通“用时间置换空间”的特殊属性，交通史的研究也应重视时间—空间的关系。驿置里程不仅仅是空间距离的一个重要指标，在实际的运行和操作中，“到京日期”就是时间信息与地理信息对应的产物，是“距离时间化”的表达方式，能直观反映交通对空间和时间的控制。驿程空间可以作为邮驿时间的参考标准，反过来，时间也是空间的一种表达方式，是计量距离可重复的实际经验的总结，在实际邮驿事务运行中，里程距离是固定的，但运行时间是变动的，这种变动带来不确定性体现了邮驿网络的动...
