Measurement Invariance of Human Values Across Time and Countries—An Analysis Using 11 Rounds of the European Social Survey

European Journal of Social Psychology, Volume 55, Issue 7, Page 1171-1196, December 2025.
ABSTRACT Values have become central to the study of social and psychological processes across cultures and across time. To date, there has been no conclusive analysis of the cross‐cultural and cross‐temporal comparability of values in Europe. We conduct invariance tests of the Portrait Values Questionnaire collected as part of the European Social ...

Global Irrigation Modeling Relies More on Pragmatic Than Empirical Assumptions

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Many global water models contain an irrigation module that simulates irrigation water withdrawals based on several assumptions on climate conditions, crop management, soil moisture, irrigation practices or water source. However, we do not know how many of these assumptions are grounded on empirical data and how many are pragmatic; that is ...

Testing the Everett Interpretation of Quantum Mechanics with Cosmology

, 2015
In this brief note, we argue that contrarily to what is still often stated, the Everett many-worlds interpretation of quantum mechanics is not in principle impossible to test.

We give a brief account of the modal logic of the generic multiverse, which is a bimodal logic with operators corresponding to the relations "is a forcing extension of" and "is a ground model of".

Within‐person association between affect and physical activity related to depressive symptomatology: A systematic review and methodological reflections

Applied Psychology: Health and Well-Being, Volume 17, Issue 6, December 2025.
Abstract Physical activity can improve mental health by improving mood and by lowering depressive symptoms. This systematic review uses a structured narrative synthesis to summarise within‐person associations between physical activity and affect in naturalistic settings, and how these associations may differ by level of depressive symptomatology.

Cosmological constant: relaxation vs multiverse

, 2019
We consider a scalar field with a bottom-less potential, such as $g^3 \phi$, finding that cosmologies unavoidably end up with a crunch, late enough to be compatible with observations if $g \lesssim 1.2 H_0^{2/3} M_{\rm Pl}^{1/3}$.

Research Review: Are sampling biases masking long‐term effects of hormonal contraceptive use in adolescence on risk for depression?

Journal of Child Psychology and Psychiatry, Volume 66, Issue 12, Page 1889-1903, December 2025.
Background Growing evidence suggests that the use of hormonal contraceptives (HCs) during adolescence may be linked to an increased risk for depression. This review examines major inconsistencies that have been reported regarding this relationship, and in particular, how the common practice of combining ‘never users’ and ‘former users’ of HCs in ...
