Linking Individual and Collective Contests through Noise Level and Sharing Rules
We propose the use of Nitzan’s (1991) sharing rule in collective contests as a tractable way of modelling individual contests. This proposal (i) tractably introduces noise in Tullock contests when no closed form solution in pure...
Does It Par-<i>tickle</i>?
Mid-air haptic feedback technology produces tactile sensations that are felt without the need for physical interactions. However, mid-air haptic experiences need to be congruent with visual cues to reflect user expectations. To...

Digital Hazards for Feeding and Eating
Abstract: Purpose of Review: We aimed to accrue recent evidence exploring effects of modern online activities (e.g., Internet use) on feeding and eating disorder symptoms, and related traits. We examined available evidence to...
New evidence on mutual fund performance
We compare two bootstrap methods for assessing mutual fund performance. The first produces narrow confidence intervals due to pooling over time, while the second produces wider confidence intervals because it preserves the...

Problematic internet use

Apr 16, 2019
OBJECTIVE: Problematic internet users suffer from impairment in a variety of cognitive domains. Research suggests that COMT haplotypes exert differential effects on cognition. We sought to investigate differences in the genetic...
When Null Hypothesis Significance Testing Is Unsuitable for Research
Null hypothesis significance testing (NHST) has several shortcomings that are likely contributing factors behind the widely debated replication crisis of (cognitive) neuroscience, psychology, and biomedical science in general....
Impulsivity in Gambling Disorder and problem gambling
Gambling Disorder is a prevalent psychiatric condition often linked to dysfunction of cognitive domains regulating impulsive behavior. Despite the centrality of impulsivity to neurobiological models of Gambling Disorder, a...
Published correlational effect sizes in social and developmental psychology.
The distribution of effect sizes may offer insights about the research done and reported in a scientific field. We have evaluated 12 412 manually collected correlation effect sizes (Sample 1) and 31 157 computer-extracted...

The efficiency of multivariate macroeconomic forecasts
We examine the efficiency of multivariate macroeconomic forecasts by estimating a vector autoregressive model on the forecast revisions of four variables (GDP, inflation, unemployment and wages). Using a data set of professional...

Cognitive deficits in problematic internet use
Konstantinos Ioannidis, Roxanne Hook, Anna E Goudriaan, Simon Vlies, Naomi A Fineberg, Jon E Grant, Samuel R Chamberlain
Feb 05, 2019
BACKGROUND: Excessive use of the internet is increasingly recognised as a global public health concern. Individual studies have reported cognitive impairment in problematic internet use (PIU), but have suffered from various...
The complex neurobiology of resilient functioning after childhood maltreatment.
BACKGROUND:Childhood maltreatment has been associated with significant impairment in social, emotional and behavioural functioning later in life. Nevertheless, some individuals who have experienced childhood maltreatment...

Improved inference in the evaluation of mutual fund performance using panel bootstrap methods
Two new methodologies are introduced to improve inference in the evaluation of mutual fund performance against benchmarks. First, the benchmark models are estimated using panel methods with both fund and time effects. Second...
The Utility of Arterial Spin Labeling MRI in Medial Temporal Lobe as a Vascular Biomarker in Alzheimer's Disease Spectrum
Efthymia Maria Kapasouri, Diomidis C Ioannidis, Donnie Cameron, Vassilios S Vassiliou, Michael Hornberger
Jan 25, 2023
We sought to systematically review and meta-analy the role of cerebral blood flow (CBF) in the medial temporal lobe (MTL) using arterial spin labeling magnetic resonance imaging (ASL-MRI) and compare this in patients with...
