As the demand for library assessment grows, academic libraries are becoming more interested in Web analytics. Data are automatically gathered and provide information about a wide variety of online interactions. Libraries have long used simple counts such as visits and page views, but have more recently begun to choose strategic benchmarks, also known as key performance indicators (KPIs). Many common KPIs were created for commercial websites and are challenging to adapt for libraries. However, the underlying concepts are sufficiently valuable that libraries should explore their use. By evaluating the validity of web metrics, libraries can further the development of standards and benchmarks to support future investigations. This article discusses how commercial web metrics might be adapted for use in academic libraries. First, the limitations of web analytics are presented. Major key performance indicators used in the commercial sector are reviewed in the academic library context. Finally, the article discusses how the various indicators might support specific library website goals and decisions and uses local data to illustrate one example case. As libraries choose web analytic methods, they should deliberately evaluate their validity. Over time, this will slowly build the profession's ability to use web analytics more effectively for library assessment. 相似文献

The LibQUAL + instrument has been widely adopted by libraries to evaluate user perceptions of library service quality. Studies combining groups (e.g., Lane et al., 2012) have shown high correlations between two factors, suggesting the possibility that a two-factor model may fit as well as the three-factor model theorized by the developers. Also, previous studies have not closely examined residuals to analyze local misfit in the context of theory but instead have often correlated error terms to improve model fit. This study uses LibQUAL + responses from undergraduates at a public, comprehensive university to test three-factor, two-factor, and one-factor models of user perceptions of library service quality. Global fit indices indicated that both two-factor and three-factor models were empirically supported, but the three-factor model had better theoretical support. Furthermore, this article adds to the literature the unique perspective of residual analysis and builds theoretical arguments in the interpretation of the final model. Areas of local misfit suggest the need for independent studies to examine residuals. If areas of misfit repeat across institutional populations, that could suggest the potential for further instrument development, while if areas of misfit are unique to institutional populations, this could target areas for institutions to investigate more closely. 相似文献

Parenting and children's temperament are important influences on language development. However, temperament may reflect prior parenting, and parenting effects may reflect genes common to parents and children. In 561 U.S. adoptees (57% male) and their birth and rearing parents (70% and 92% White, 13% and 4% African American, and 7% and 2% Latinx, respectively), this study demonstrated how genetic propensity for temperament affects language development, and how this relates to parenting. Genetic propensity for negative emotionality inversely predicted language at 27 months (β = −.15) and evoked greater maternal warmth (β = .12), whereas propensity for surgency positively predicted language at 4.5 years (β = .20), especially when warmth was low. Parental warmth (β = .15) and sensitivity (β = .19) further contributed to language development, controlling for common gene effects. 相似文献
