Remote elementary education: a comparative analysis of learner development (part 1) by Stefan Kleinke, David Cross

“…While preexisting group differences, selection biases and testing inconsistencies could be effectively ruled out as potential causes for the observed differences, other factors such as developmental and environmental differences between the learning environments seemed to be influential. …”

Better than blocking: building and using multiple variable pattern indexes (MVPi) to screen data sources for possible matches and reduce linkage search space by Sigurd Hermansen

“…Conclusion/Implications The screening phase of a large-scale linkage project reduces linkage search space to the pairs of records more likely to be true matches, but it may also lead to selectivity bias and underestimates of the sensitivity (recall) of data linkage methods. …”

Precision stratification of prognostic risk factors associated with outcomes in gestational diabetes mellitus: a systematic review by Zhila Semnani-Azad, Romy Gaillard, Alice E. Hughes, Kristen E. Boyle, Deirdre K. Tobias, ADA/EASD PMDI, Wei Perng

“…However, using the Diabetes Canada 2018 Clinical Practice Guidelines for studies, the level of evidence was low due to potential for confounding, reverse causation, and selection biases. Conclusions GDM pregnancies with greater severity, as well as those accompanied by maternal obesity, unhealthy diet, and low physical activity, as well as cases that occur among women who identify as racial/ethnic minorities are associated with worse cardiometabolic prognosis in mothers and offspring. …”

Herschel reveals a Tdust-unbiased selection of z~ 2 ultraluminous infrared galaxies by Magdis, G, Elbaz, D, Hwang, H, Amblard, A, Arumugam, V, Aussel, H, Blain, A, Bock, J, Boselli, A, Buat, V, Castro-Rodríguez, N, Cava, A, Chanial, P, Clements, D, Conley, A, Conversi, L, Cooray, A, Dowell, C, Dwek, E, Eales, S, Farrah, D, Franceschini, A, Glenn, J, Griffin, M, Halpern, M

“…We conclude that Herschel observations confirm the existence of high-z ULIRGs warmer than SMGs, show that the mid-IR selection of high-z ULIRGs is not Td dependent, reveal a large dispersion in Td of high-z ULIRGs and provide the means to characterize the bulk of the ULIRG population, free from selection biases introduced by ground-based (sub)mm surveys. © 2010 The Authors. …”

“…We compare the bulk densities for the full sample, which includes planets ranging in size from 0.52 R _⊕ to 12.8 R _⊕ , and find that single planets have significantly lower densities on average than multis, which we cannot attribute to selection biases. We compare the bulk densities normalized by an Earth model for planets with R _p < 6 R _⊕ and find that multis are also denser with 99% confidence. …”
