关键词： 持久标识符   区块链   Handle系统   标识解析  

摘要： 随着信息产业的发展,数据生产者产生了大量价值数据.为了进行数据共享,赋予数据相应的标识符用于解析数据所在位置,同时为使数据可长期通过标识符访问,还需保证标识符解析服务长期可用,但现有标识符系统多数采用半去中心化结构,由于过于依赖最终解析服务,其中部分系统由于各种原因逐渐丧失解析能力.本文基于区块链系统的分布式账本数据一致性,提出了一种基于区块链的持久标识符系统,在兼容现有标识符系统访问层的基础上,提供存储层以保证标识符解析服务持久性及数据的长期正确保存.基于Handle系统及Hyperledger Fabric的测试结果表明,该系统能够在提供可接受的请求响应速度与存储占用率的前提下,为持久标识符服务提供更好的数据完整性与解析服务长期可用性.

摘要： 数字对象唯一标识符(digital object identifier,DOI)是对包括互联网信息在内的数字信息进行标识的一种工具。在传统的出版物中,书刊、磁带、光盘都有国际标准编号(ISBN、1SSNJSCN)及其条形码,作为出版物的唯一标识.这些标识使出版物得到有效的管理,便于读者杳找和利用而网上的文档一旦变更了网址便无从追索.

关键词： 卫生信息   标识体系   对象标识符   注册管理  

摘要： 以我国卫生信息业务需求为导向,设计了涵盖标识注册机构设置、管理流程制定、标识分配、注册解析系统开发和实施与推广应用5个方面内容的卫生信息标识体系.提出了国家、省级和市级三级注册管理层级,明确了每一级注册中心所具备的管理职能.并从注册机构申请规程和对象标识符管理规程两个层面,展开注册操作规程设计,提出注册分中心、其他实体机构注册流程,以及卫生信息对象标识符类型、分配、争议处理、维护等方面的管理规程,从而推进我国卫生信息开放系统互联对象标识符落地实施.

关键词： telepsychiatry   access   barriers   emergency care   implementation  

摘要： Objectives: To report on the perceived barriers surrounding the use of telepsychiatry for emergency assessments and our approach to overcoming those barriers to achieve successful implementation of a program to increase access to emergency psychiatric assessment in a Canadian urban setting. Methods: We conducted a survey of emergency care staff to inform the implementation of an emergency telepsychiatry program in the urban setting of Winnipeg, Manitoba, where hospitals have variable on-site emergency psychiatric coverage. We analyzed survey responses for perceived barriers we would need to address in implementation. We employed implementation strategies for each barrier and scaled the program to three sites over the first year. Data from the first year were collected including number of telepsychiatry assessments, reasons for referral, wait time, and percentage of patient transfers avoided. Results: Survey respondents (N = 111) had little prior exposure to telepsychiatry, but the majority were open to its use for emergency psychiatric assessments in the region. We identified three categories of perceived barriers: clinical, logistical/technical, and readiness barriers. Implementation planning addressed each barrier, and a hub-and-spoke program was launched. After the first year, the program had one hub serving three spokes, and 243 emergency telepsychiatry assessments had been completed. After 12 months, we were avoiding 65% of patient transfers. Conclusions: By conducting a user survey to identify perceived barriers, and addressing these during implementation, we successfully scaled our emergency telepsychiatry program across our region. Our report of this experience may benefit others attempting to implement a similar program.

摘要： Recent scholarship has reported that identification as a liberal or conservative shapes lifestyle orientations and behaviors. Liberal/conservative differences with respect to such arenas as family and religion go beyond ideological identification research's traditional focus on policy attitudes and political processes. But are differences on non-political issues as large as those relating to political ones? This question has yet to be addressed, and it is critical to putting in firmer perspective the degree to which liberal and conservative identifiers differ in the United States. We take up investigation through analysis of 106 items from the General Social Survey 2006 panel. We compare ideological identification's influence with respect to political versus non-political orientations and behaviors. Application of Morgan and Winship's model of causal inference builds from past studies' cross-sectional analysis. Results extend ideological identification scholarship, while cautioning against wide-ranging claims advanced by several public commentators.
