In the era of “big data” revolution, social scientists face different types of challenges that we think are more technical, rather than theoretical. While it is certainly a challenge to analyze bigger than tera-byte data, the analysis of big data is not just a matter of solving computational problems. Big data provides a unique opportunity to solve society’s big problems if and only if it is analyzed through careful research designs and strong theoretical frameworks. This talk introduces two practical strategies for social scientists — parallel aggregation and matching — to make big data smaller so that we can overcome technical difficulties while making robust statistical inference. I will illustrate them based on my own trial and error during the analysis of large-scale medical claims data under the context of the US opioid epidemic. This talk also presents several tips for the effective management of big data.
Publication and reporting bias are well-documented in the scientific literature. Increased data and code sharing, and access to other sources of information such as Clinical Study Reports (CSRs), address concerns about the non-reproducibility of individual studies. Ironically, greater transparency has given rise to new problems. That is, systematic reviewers and meta-analysts can choose from among dozens of effect sizes that could be included in their analyses. Initiatives that increase validity and reproducibility in individual studies also create opportunities for bias in research synthesis and clinical guideline development. Scientists could adopt new methods to avoid cherry-picking at all stages of research and evidence synthesis.
The Portraits of Pioneers in thereapeutic recreation in this video offer glimpses into the personal and professional lives of some of the giants in the history of therapeutic recreation. The individuals whose lives are portrayed were selected by PALAESTRA magazine in 2001.
Indiana University. Department of Radio and Television.
Summary:
The Indiana School of the Sky radio program of the Indiana University Department of Radio and Television began broadcasting educational radio programs in 1947 and continued through the early 1960s. The program reached schools throughout Indiana and nearby states and led to new course offerings at IU. Indiana University students performed in the radio programs originally intended for children ages 4-8 aired for 15 minutes during each school day. Eventually the popularity of the programs called for high school programming as well, and later adults also tuned into the programs. This collection contains recordings of these programs.
