Calendars and keys: The classification of “home” and “work”

This article presents a discussion of the relationship between classification systems and individuals' everyday activities. The concept of “boundary work” is defined as the practices that concretize and give meaning to mental frameworks by placing, maintaining, and challenging cultural categories. “Home” and “work” provide a case study for examining boundary work across a range of realm relationships, from those that are highly “integrating” to those that are highly “segmenting.” Boundary practices involving calendars and keys, clothes and appearances, eating and drinking, money, people and their representations (like photographs and gifts), talk styles and conversations, reading materials and habits, and work breaks (including lunches and vacations) are discussed. Mary Douglas's work on categorical purity helps illustrate the relationship between cognitive order and visible behavior seen in the boundary work of home and work. This article includes material that was published in a larger study,Home and Work: Negotiating Boundaries Through Everyday Life (1996 University of Chicago Press), after it was presented at the 1995 Eastern Sociological Society meetings in Philadelphia.     

基于分类特征视角的无形资产计量研究

在知识经济时代，无形资产已成为第一资源，以可靠性和历史成本为核心的传统的无形资产会计核算制度已不能适应以知识和技术为内核的知识经济时代的新要求。为此，对现有无形资产会计核算进行整合创新，从元形资产的大类特征入手，分门别类探讨不同类型无形资产的会计处理方法，以期有效增强会计信息的决策有用性，提升企业的核心竞争力。     

代价敏感的GEP分类算法实现

在数据挖掘领域中,通常以分类精度作为分类算法效果的评估标准。这一标准是建立在假设任意一实例被误分类为任意类时都具备同样代价的基础上的。当此假设不成立时,直接使用传统分类方法就无法取得良好的分类和预测效果。针对这一问题,通过改进编解码方法以及在适应度函数中集成样本的不同误分类代价,提出了一种基于基因表达式程序设计的代价敏感分类算法(CSC-GEP),并在三个UCI数据集上对该算法进行了测试,实验结果表明CSC-GEP是一种有效的代价敏感分类算法。

网络课程学习目标与学习模式

网络课程学习主要以自主学习和协作学习为主,网络课程学习者有着自身的年龄特点、学习行为特点和心理特点;要实现网络课程的认知、技能、情感和道德等学习目标,必须制定与其相适应的自主学习模式、协作学习模式、虚拟学习模式和移动学习模式。只有这样,网络课程学习者才能提高学习效率,取得良好的成绩。     

论中国诗歌的分类——对诗歌两分法的质疑

半个世纪以来,我国学术界通行将诗歌分为抒情诗和叙事诗两大类.这种两分法有悖于我国三千年诗歌史的实际,有悖于分类学原理和传统分类法,也有悖于西方文学分类理论,是不全面、不科学的.从我国诗歌的内容性质及基本表达方式看,分为抒情诗、叙事诗、说理诗、写景状物(景物)诗四大类是比较适当的.     

Voluntary income sharing and the design of unemployment insurance

This paper uses a model of search unemployment to discuss the interaction between publicly provided insurance and informal insurance through voluntary income sharing, e.g., between spouses. Income sharing reduces the optimal level of public unemployment insurance. While it is always individually rational for partners to share income, the effect of voluntary income sharing on welfare will be negative unless partners can either observe each other's search behavior or are sufficiently altruistic towards each other. The model is also used to examine a family-based policy. The welfare gains from using such policy are argued to be small. Received: 14 December 2000/Accepted: 5 November 2001     

Enclaves, neighbourhood effects and employment outcomes: Ethnic minorities in England and Wales

Ethnic minorities in England and Wales are spatially concentrated in relatively-deprived urban areas. Both geographic clustering and the economic characteristics of ethnically-concentrated neighbourhoods can impact upon the opportunities and constraints facing residents of such areas. This paper explores the relationship between the existence of enclaves and the employment prospects of ethnic minorities in England and Wales. It is shown that there is considerable spatial variation in employment outcomes. There is a lower incidence of self-employment in more ethnically-concentrated urban areas, which contradicts the view of ethnic entrepreneurship as an enclave phenomenon. Unemployment rates are also higher for minorities living in more concentrated areas. Enclaves in England and Wales do not appear to offer many economic benefits to minority individuals.

从文献著录看“七体”的演变

“七”在中国古代文体史上立为一体，由来已久，其文体地位在古代史书、类书、书目等文献中都有明确的著录；随着创作的发展变化，七体在后世总集中的归类及收录范围有所变化，据此可以更深入地探讨七体的文体属性和发展演变，也可看出文体分类及演变过程中的复杂性和多样性。
