Improving the Value of CDS-I for the User Community

收入动态小组研究（PSID）是一项对美国个人及其家庭的代表性样本进行的纵向研究。从1968年开始，这是同类小组中运行时间最长的。PSID的儿童发展补充（CDS）是收集儿童及其家庭的广泛数据集，目的是了解儿童的社会人口，心理和经济方面。这个当前nsf资助的项目的首要目标是通过对1997年收集的第一波cd进行重要改进来增加整个PSID-CDS数据档案。这些改进中的大多数将使用数据库软件中的最新技术进步，并且已经应用于PSID数据和第二波CDS数据。具体而言，该项目将(a)利用最近在创建电子代码本数据库方面的技术进步，为光盘- 1提供更丰富的文件，使光盘- 1文件能够纳入用户友好的、尖端的psid -光盘- 2网络数据档案；(b)建立与联机数据中心结合并可通过联机数据中心查阅的跨年变量索引，从而简化变量的识别和选择；(c)为非传染性疾病一级儿童建立为非传染性疾病二级儿童开发的数据共同核心联系和变量，使用户能够研究1997年非传染性疾病一级儿童学校的特点；(d)提供描述儿童在cd - i中观看的媒体节目内容的数据。该项目将通过使CDS-I数据更易于使用和获取，并与更大的PSID和CDS-II数据库相结合，对加强科学理解作出广泛贡献。PSID-CDS数据具有“代际”结构，其信息包含在来自多个家庭成员的33波数据中，使分析人员能够将儿童、其父母、祖父母和其他亲属的信息完全联系起来。该项目的完成将使来自不同学科的研究人员和学生能够访问这些数据。此外，该项目的活动将通过互联网（www.psidonline.isr.umich.edu）为研究人员提供额外的数据工具和专业知识，从而为新兴的电子科学网络基础设施做出贡献，从而实现对高度复杂的数据档案的访问，而不考虑地理位置。这种开放获取将带来更大的长期经济利益，使政府决策者获得更好的信息，并加速科学本身的进步（见《科学》，2004年3月19日）。最后，数据处理、记录和传播活动是教学工具，可以用来向不同的受众教授研究概念。他们已经被用来教本科生甚至高中生，以及来自世界各地的学术研究人员。

The Panel Study of Income Dynamics (PSID) is a longitudinal study of a representative sample of U.S. individuals and their families. Beginning in 1968, this is the longest running panel of its kind. The Child Development Supplement (CDS) of the PSID is an extensive data set on children and their families collected with the goal of understanding socio-demographic, psychological, and economic aspects of childhood. The overarching objective of this current NSF-funded project is to augment the entire PSID-CDS data archive by making important improvements to the first wave of CDS, collected in 1997. Most of these improvements will use recent technological advancements in database software, and have already been applied to PSID data and the second wave of CDS data. Specifically, the project will (a) provide richer documentation for CDS-I that takes advantage of recent technological advances in the creation of electronic codebook databases, allowing CDS-I documentation to be integrated into the user-friendly, cutting-edge PSID-CDS-II web-based data archive; (b) create a cross-year variable index that is integrated with and accessible through the online data center, which will streamline variable identification and selection; (c) create Common Core of Data (CCD) linkages and variables for CDS-I children as developed for CDS-II children, allowing users to study characteristics of schools for the CDS children as of 1997; and (d) provide data describing the content of media programming watched by children in CDS-I. The project will contribute broadly to enhancing scientific understanding by making the CDS-I data more usable, accessible, and integrated with the larger PSID and CDS-II databases. The PSID-CDS data are 'intergenerational' in structure with information contained in 33 waves of data from multiple family members, allowing analysts to fully link information on children, their parents, their grandparents, and other relatives. The completion of the project will give researchers and students from a variety of disciplines access to the data. Furthermore, the activities of this project will contribute to the emerging e-science cyber infrastructure by providing additional data tools and expertise via the Internet (www.psidonline.isr.umich.edu) to researchers so that access to a highly complex data archive is achieved without regard to geographic location. This open access will lead to greater long-term economic benefits, better-informed government decision-makers, and accelerated progress in science itself (see Science, March 19, 2004). Lastly, the data processing, documentation, and dissemination activities are pedagogical tools that can be used to teach research concepts to a diverse audience. They have been used to teach undergraduate and even high school students, as well as academic researchers from all over the world.
