Generalised Versus Specific Internet Use-Related Addiction Problems: A Mixed Methods Study on Internet, Gaming, and Social Networking Behaviours

open access: yesInternational Journal of Environmental Research and Public Health, 2018
The field of technological behavioural addictions is moving towards specific problems (i.e., gaming disorder). However, more evidence of generalised versus specific Internet use-related addiction problems (generalised pathological Internet use (GPIU) vs.

On the Multilinear Restriction and Kakeya conjectures [PDF]

open access: yes, 2005
We prove $d$-linear analogues of the classical restriction and Kakeya conjectures in $\R^d$. Our approach involves obtaining monotonicity formulae pertaining to a certain evolution of families of gaussians, closely related to heat flow.

Challenges in homology search: HMMER3 and convergent evolution of coiled-coil regions

open access: yesNucleic Acids Research, 2013
Detection of protein homology via sequence similarity has important applications in biology, from protein structure and function prediction to reconstruction of phylogenies. Although current methods for aligning protein sequences are powerful, challenges

Toolmaking and the evolution of normative cognition

open access: yesBiology & Philosophy, 2021
We are all guided by thousands of norms, but how did our capacity for normative cognition evolve? I propose there is a deep but neglected link between normative cognition and practical skill.

A Discrete Dynamical Model of Signed Partitions

open access: yesJournal of Applied Mathematics, 2013
We use a discrete dynamical model with three evolution rules in order to analyze the structure of a partially ordered set of signed integer partitions whose main properties are actually not known.

Contractive adjustment in Mexico, 1982-1989

open access: yesPSL Quarterly Review, 2013
The work assesses the macroeconomic effects of the IMF’s contractive adjustment strategy in Mexico’s recent evolution, while raising some theoretical challenges to several of the underlying assumptions that have sustained the Mexican government’s recent ...
