Improving the Value of CDS-I for the User Community

收入动态小组研究（PSID）是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，这是同类产品中运行时间最长的面板。 公共部门发展研究所的儿童发展补充资料是一套关于儿童及其家庭的广泛数据集，其目的是了解儿童的社会人口、心理和经济方面。 目前NSF资助的项目的首要目标是通过对1997年收集的第一波CDS进行重要改进来增加整个PSID-CDS数据档案。 其中大多数改进将利用数据库软件方面的最新技术进步，并已应用于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码本数据库方面取得的技术进步，为CDS-I提供更丰富的文件，使CDS-I的文件能够纳入方便用户的、先进的PSID-CDS-II网络数据档案;（B）创建与在线数据中心集成并可通过在线数据中心访问的跨年度变量索引，（c）为综合发展服务第一阶段的儿童建立为综合发展服务第二阶段的儿童建立的共同核心数据联系和变量，使用户能够研究截至1997年综合发展服务儿童的学校特点;及（d）提供描述儿童在CDS-I中观看的媒体节目的内容的数据。该项目将通过使CDS-I数据更有用、更容易获得并与更大的PSID和CDS-II数据库相结合，广泛地促进提高科学认识。PSID-CDS数据在结构上是“代际”的，信息包含在来自多个家庭成员的33波数据中，使分析师能够将儿童、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获得数据。 此外，该项目的活动将通过互联网（www.psidonline.isr.umich.edu）向研究人员提供更多的数据工具和专门知识，从而有助于新兴的电子科学网络基础设施，以便能够不受地理位置的限制地访问高度复杂的数据档案。 这种开放获取将带来更大的长期经济利益，更好地了解政府决策者，并加速科学本身的进步（见Science，2004年3月19日）。 最后，数据处理、文件编制和传播活动是教学工具，可用于向不同受众传授研究概念。 它们已被用于教授本科生，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.
