Evaluation of a weighting approach for performing sensitivity analysis after multiple imputation.
BACKGROUND: Multiple imputation (MI) is a well-recognised statistical technique for handling missing data. As usually implemented in standard statistical software, MI assumes that data are 'Missing at random' (MAR); an...
Utilizing MAR for Remedial Teaching of Compound-Cube-Surface Area at Elementary School in Taiwan
In this paper, the development of the MAR (mobile augmented reality) remedial teaching program is described. It allowed students to manipulate augmented objects through AURASMA app via internet and find leads to solve geometry...

Analyses of Sensitivity to the Missing-at-Random Assumption Using Multiple Imputation With Delta Adjustment
Multiple imputation with delta adjustment provides a flexible and transparent means to impute univariate missing data under general missing-not-at-random mechanisms. This facilitates the conduct of analyses assessing sensitivity...

The anterior insula bidirectionally modulates cost-benefit decision-making on a rodent gambling task.
Deficits in cost-benefit decision-making, as assessed in the Iowa Gambling Task (IGT), are commonly observed in neuropsychiatric disorders such as addiction. There is considerable variation in the maximization of rewards on such...
Parasite-associated mortality in a long-lived mammal
Parasites can cause severe host morbidity and threaten survival. As parasites are generally aggregated within certain host demographics, they are likely to affect a small proportion of the entire population, with specific hosts...
Movement seasonality in a desert-dwelling bat revealed by miniature GPS loggers.
BACKGROUND: Bats are among the most successful desert mammals. Yet, our understanding of their spatio-temporal dynamics in habitat use associated with the seasonal oscillation of resources is still limited. In this study, we...

El mismo mar de todos los veranos de Esther Tusquets narra la tormentosa relación erótica y emocional de una mujer de la alta burguesía catalana, casada y desencantada, que ejerce de profesora de literatura, con una joven...
A general method for elicitation, imputation, and sensitivity analysis for incomplete repeated binary data.
We develop and demonstrate methods to perform sensitivity analyses to assess sensitivity to plausible departures from missing at random in incomplete repeated binary outcome data. We use multiple imputation in the not at random...
High-Throughput Machine-Learning-Driven Synthesis of Full-Heusler Compounds
A machine-learning model has been trained to discover Heusler compounds, which are intermetallics exhibiting diverse physical properties attractive for applications in thermoelectric and spintronic materials. Improving these...
Linear Increments with Non-monotone Missing Data and Measurement Error.
Linear increments (LI) are used to analyse repeated outcome data with missing values. Previously, two LI methods have been proposed, one allowing non-monotone missingness but not independent measurement error and one allowing...

The limited availability of resources is predicted to impose trade-offs between growth, reproduction and self-maintenance in animals. However, although some studies have shown that early reproduction suppresses growth...
Design Principles of Mobile Learning Frameworks
Numerous studies show positive cognitive and affective results regarding the adoption of mobile learning; however, adoption levels are low, and when mobile learning occurs, it is not always based on innovative pedagogies. The...

Microglial phagocytosis of neurons in neurodegeneration, and its regulation.
Claire A Butler, Alma S Popescu, Emily JA Kitchener, David H Allendorf, Mar Puigdellívol, Guy C Brown
Mar 02, 2021
There is growing evidence that excessive microglial phagocytosis of neurons and synapses contributes to multiple brain pathologies. RNA-seq and genome-wide association (GWAS) studies have linked multiple phagocytic genes to...
