We report the results of a preregistered, cluster randomized controlled trial mathematics learning intervention known as interleaved practice. Whereas most assignments consist block problems devoted to same skill or concept, an assignment is arranged so that no 2 consecutive require strategy. Previous small-scale studies found practice with greater proportion produced higher test scores. In present study, we assessed efficacy and feasibility in naturalistic setting large, diverse sample....

Renal revascularization is performed in 16% of newly diagnosed patients with atherosclerotic renovascular disease (ARVD). Although there may be some improvement hypertension control as a result intervention, renal functional outcomes are known to vary. Pre-existing parenchymal injury, manifested by proteinuria, associated poor outcome conservatively managed ARVD patients, but this association has not been investigated undergoing revascularization.Retrospective case note review 83 who...

To describe the geographical heterogeneity of COVID-19 across prefectures in mainland China, we estimated doubling times from daily time series cumulative case count between 24 January and February 2020. We analyzed prefecture-level burden using linear regression models used local Moran’s I to test for spatial autocorrelation clustering. Four hundred (~98% population) had at least one 39 zero cases by Excluding Wuhan those where there was only or none, 76 (17.3% 439) an arithmetic mean...

This study examined conceptual changes in children the dimension of explicitness through lens representational redescription model (A. Karmiloff-Smith, 1986, 1992). The 4- to 9-year-old participants (N = 24) had balance blocks on a narrow support one task and predict whether could be balanced another task. In addition application microgenetic approach, various new methods were introduced capture fine-grained explicitness. Explicit understanding behavioral performance assessed separately with...

The coronavirus disease 2019 (COVID-19) pandemic prompted universities across the United States to close campuses in Spring 2020. Universities are deliberating whether, when, and how they should resume in-person instruction Fall In this essay, we discuss some practical considerations for use of 2 potentially useful control strategies based on testing: (1) severe acute respiratory syndrome (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) testing followed by case-patient...
