电信产业的价格竞争模型与接入费水平

互联互通之后，信息产业部对接入费水平的制定原则是接入费水平基于接入成本．主要讨论如何把握这个原则的问题．通过建立两个电信运营商的价格竞争模型，分析比较价格竞争之前和价格竞争之后各个运营商的状况，从而为研究此类问题提供一种新的思路．     

PCS网络中一种改进的呼叫建立算法

PCS系统中,用户漫游到非归属VLR覆盖区被呼时,系统将产生大量信令开销和数据库访问开销。该文为移动用户被呼提出了一种改进的缓冲呼叫算法来降低网络信令开销与数据库访问负荷和呼叫建立时延,建立了一种模型来分析其相关性能。与传统呼叫算法相比,改进呼叫算法能极大降低系统开销,具有较强的可行性。     

Microdata Access and Labor Market Research: The U. S. Experience

Summary: The paper illustrates the value of broad researcher access to survey and administrative microdata using examples drawn from the U. S. experience, outlining how analyses of trends in earnings inequality, poverty and employment dynamics using such data have benefited policy makers and contributed to improvements in statistical agency data products. Methods of facilitating researcher access, including the release of public use files, the use of licensing agreements, and the establishment of research data centers, are discussed. * The author thanks Anne Polivka, Marilyn Seastrom and two anonymous referees for helpful comments on an earlier draft of the paper.

论完善注册会计师及相关特种执业资格准入机制

现有法律、法规及规章没有规定资产评估机构、房地产估价机构、造价工程师执业机构的准入条件,各特种执业资格准入机制存在准入条件相差较大,个别执业资格准入条件偏低,准入考试内容设置不合理等缺陷。应提高注册会计师及相关特种执业资格准入条件,合理设置准入考试或考察内容,建立会计师事务所各特种执业资格注册管理制度。     

一种双层小区结构中的切换控制策略

在宽带码分多址双层小区结构系统中提出了一种基于小区覆盖范围和信号能干比判决的切换策略,切换策略使用了基于概率的动态资源预留方案,即在切换时,如果系统中没有空闲资源,则对切换呼叫进行排队。通过仿真表明,该切换策略相对于采用固定资源预留的切换策略,在轻负荷的条件下对话音呼叫的阻塞概率有一定的改善。     

略论期刊编辑部远程办公的实现

期刊编辑部通过在网站上建立远程办公系统,可实现家庭办公和异地办公。远程办公室主页主要由办公室、会议室、会客室、阅览室、财务室、广告部、发行部等职能部门组成。其中,办公室又分主编室、专业编辑室等,主编可定期在会议室召开会议,各编辑和作者、读者相约在会客室交流。规范的约稿函、修稿函、催版面费函等,可利用邮件系统发送,而审稿费、稿费、版面费等可在财务室通过网上银行转账。作者投稿时可直接进入编辑室对口专业的"办公桌",编辑可在自己"办公桌"上编排校稿件,提交给主编,实现局域网办公、因特网办公等远程办公的功能。利用该系统,可外聘编辑(甚至异地的编辑),本编辑部的编辑也可在别的杂志社兼职,为建立网上编辑部提供了技术支持。     

Cultural Anthropology and Open Access—Interview With Dominic Boyer,Cymene Howe,and Marcel LaFlamme

Abstract

In this installment of “Conversations,” Dominic Boyer, Cymene Howe, and Marcel LaFlamme, of the Cultural Anthropology editorial team, discuss the ins and outs of publishing a gold open access journal in the field of anthropology. Highlights of the discussion include Cultural Anthropology’s move to open access, the ethics of open access, the growth of international readership, ongoing publishing challenges in open access, and the role libraries can play with open access publishing.     

Preserving Open Access

Abstract

Libraries have an established track record of preserving the scholarly record, but this stewardship role has generally been exercised over materials the library has purchased or otherwise acquired. With open access publishing, the library’s role in preservation is less certain, as libraries may facilitate access to a wide array of freely accessible materials without ever obtaining any copies. Additionally, the open access landscape includes many small noncommercial publishers with limited resources that may not be able to invest in long term preservation and access. In this column, Courtney McAllister, Electronic Resources Librarian at Lillian Goldman Law Library, Yale University, discusses preservation concerns and strategies for open access publications and how libraries may be affected by unstable or unpredictable long-term access.     

Compensation or competition: Bias in immigrants' access to active labour market measures

Whether participation in active labour market programmes (ALMPs) pushes individuals back into employment depends on the programme's characteristics. On the basis of encompassing registry data that allow us to control for usually unobserved employability, we find evidence of a systematic access bias whereby jobcentre caseworkers in Switzerland assign unemployed persons to activation measures based on a competition logic that is mainly driven by an economic rationale and the jobcentre's performance evaluation. This practice seems problematic because it results in an overrepresentation of immigrants in measures with little efficacy rather than in measures that could compensate for employability disadvantages. Conversely, Swiss citizens are more likely to enter beneficial human-capital-intensive measures. It is plausible that this discrepancy in programme participation amplifies the general labour market disadvantages of immigrants.
