A New Direction for Library Technical Services: Using Metadata Skills to Improve User Accessibility

Abstract

An increased awareness about the importance of resource accessibility for all library users has set the stage for transforming traditional cataloger roles into a new realm of possibility. The Acquisitions & Discovery (A&D) and the User Experience (UX) departments of North Carolina State University Libraries have formed a partnership to explore the benefits of working together amidst this climate of innovation and change. A pilot project was created to develop a workflow through which technical services staff can use their metadata skills to help resolve accessibility issues found on the Libraries’ main website. By performing this work, staff can grow in technical expertise, enhance the quality of metadata in web content, and build mutually beneficial partnerships within the library community.     

数量分析方法的选择与应用——来自课程作业和建模竞赛的思考

从数量分析方法中的多解现象展开研究,分析了多解存在的原因：结论的语境、随机成分和错误的模型,并针对数量分析方法误用展开进一步讨论：（1）建模过程的要点;（2）理论与逻辑在建模过程中的作用。最后给出结论和建议。     

An Asymptotic Characterization of Finite Degree U-statistics With Sample Size-Dependent Kernels: Applications to Nonparametric Estimators and Test Statistics

We provide a simple result on the H-decomposition of a U-statistics that allows for easy determination of its magnitude when the statistic’s kernel depends on the sample size n. The result provides a direct and convenient method to characterize the asymptotic magnitude of semiparametric and nonparametric estimators or test statistics involving high dimensional sums. We illustrate the use of our result in previously studied estimators/test statistics and in a novel nonparametric R² test for overall significance of a nonparametric regression model.
