British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability is crucial in psychometrics, reflecting the extent to which a measurement instrument can discriminate between individuals or items. While classical test theory and intraclass correlation coefficients are well‐established for quantitative scales, estimating reliability for binary outcomes presents unique challenges due to their ...

Decline of Visual Function and Risk of Legal Blindness With Age in RPGR‐Associated Retinal Degeneration: A Multicenter Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background This retrospective multicenter longitudinal analysis analysed the loss trajectory of best recorded visual acuity (BRVA) and Goldmann visual field (GVF) in RPGR‐associated retinal degeneration (RPGR‐RD). Methods Patients with genetically confirmed RPGR‐RD were classified into rod‐cone (RC), cone/cone‐rod (CR) and female‐carrier ...

The Role of Index Fund Ownership in the Era of Say‐on‐Pay

Financial Management, EarlyView.
ABSTRACT We examine whether and how index funds influence executive compensation in the post‐Say‐on‐Pay era. Using the annual reconstitution of the Russell indexes as a source of exogenous variation in index fund ownership, we document a causal effect of index ownership on CEO pay structure.

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function

International Statistical Review, EarlyView.
Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range

Social media, high‐frequency trading, and market making after‐hours – Evidence from presidential tweets

Journal of Financial Research, EarlyView.
Abstract I analyze differences between the core and extended trading sessions in the high‐frequency reaction of equity markets to potential news. Using presidential tweets as unanticipated, potentially market‐stirring events, I find that volatility increases and liquidity deteriorates within fractions of a second after a tweet.
