Data‐Driven Materials Science for Energy‐Sustainable Applications

open access: yesAdvanced Materials, EarlyView.
Data‐driven approaches powered by artificial intelligence are transforming materials discovery for energy sustainability. This review examines how auto‐generated high‐quality materials databases and domain‐specific language models accelerate research in photovoltaics, thermoelectrics, batteries and magnetic materials. Applications involve extraction of

Review of Inorganic Separator Engineering for Next‐Generation Lithium–Sulfur Batteries: Compromise or Cornerstone?

open access: yesAdvanced Materials, EarlyView.
Inorganic compound‐modified separators transform lithium–sulfur batteries from passive polysulfide confinement to active reaction‐pathway regulation. A Practical Relevance Index (PRI)‐guided framework bridges interfacial chemistry of inorganic separators with practical constraints, establishing unified design principles for scalable, high‐energy ...

External Validity

open access: yes, 2017
A threat to external validity is any factor that limits the generalizability of an observed result. Unlike all threats to statistical conclusion and internal validities and some threats to construct validity, threats to external validity cannot ordinarily be controlled by design.

Beyond External Validity

Journal of Consumer Research, 1983
s it is usually phrased, the question of external validity has to do with whether the results of a behavioral study would hold for other persons, settings, times, or places. Consistent with the original notions of Campbell and Stanley (1966) and Cook and Campbell (1977), we have argued that this concept of external validity is rela­tively less ...

The Concept of External Validity

Journal of Consumer Research, 1982
Many researchers feel that external validity must be emphasized even in theoretical research. The argument for both a sophisticated and a common sense version of this contention is refuted in this paper. It is concluded that the very nature of progress in theoretical research argues against attempting to maximize external validity in the context of any

[External validity].

Zeitschrift fur Evidenz, Fortbildung und Qualitat im Gesundheitswesen, 2008
It is widely accepted that clinical trials have to be carefully reviewed for internal validity. In addition, aspects of external validity, which is also known as 'generalizability' or 'directness', must be considered. The question of whether the study results can be applied to clinical practice under different conditions than the study itself is of ...

Target Validity: Bringing Treatment of External Validity in Line with Internal Validity [PDF]

open access: yesCurrent Epidemiology Reports, 2020
Purpose of Review: "Target bias" is the difference between an estimate of association from a study sample and the causal effect in the target population of interest. It is the sum of internal and external bias.

External validation of the CRAX2MACE model

Journal of Nuclear Cardiology, 2023
Single-photon emission computed tomography (SPECT) myocardial perfusion is frequently used to predict risk of major adverse cardiovascular events (MACE). We performed an external validation of the CRAX2MACE score, developed to estimate 2-year risk of MACE in patients with suspected coronary artery disease (CAD).Patients who underwent clinically ...

A conceptual framework for external validity

Journal of Biomedical Informatics, 2021
Evidence-Based Medicine (EBM) encourages clinicians to seek the most reputable evidence. The quality of evidence is organized in a hierarchy in which randomized controlled trials (RCTs) are regarded as least biased. However, RCTs are plagued by poor generalizability, impeding the translation of clinical research to practice. Though the presence of poor

Patterns of external validity

2008
Generalizability depends on the quality of the prediction model as developed for the development setting (internal validity), and on characteristics of the population where the model is applied (validity of regression coefficients and distribution of predictor values). The general framework of validity of predictions was discussed in Chap.
