Advancing Robust Governance in Turbulent Times: The Role of Multi‐Level Governance, Hybrid Governance, and Negotiated Societal Intelligence

open access: yesPublic Administration, EarlyView.
ABSTRACT New research argues that robust governance based on flexible adaptation and proactive innovation is needed in order to uphold core public functions, purposes, and values in times of societal turbulence. However, we have limited knowledge of the conditions for enhancing robust governance.

Photometric Analysis of the Cataclysmic Variable Star LT Eri

open access: yesThe Astronomical Journal
LT Eri is a long-period eclipsing cataclysmic variable star (CV). This study investigates its outbursts, negative superhumps (NSHs), tilted-disk precession, eclipse-depth variations, and observed minus calculated ( O – C ) behavior, using photometric ...

Disarticulations in Naples: Cultural political ecology, the green transition, and labour unrest at a Whirlpool factory

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Abstract This article develops a cultural political ecology approach to disarticulations and labour unrest. The reference point for analysis is a struggle at a Whirlpool factory in Naples that the company announced would close in 2019, six months after signing an agreement with the Italian government, including a multi‐million investment plan.

Evolution of Cataclysmic Variables with Binary-driven Mass Loss during Nova Eruptions

open access: yesThe Astrophysical Journal
The discrepancies between observations and theoretical predictions of cataclysmic variables (CVs) suggest that there exists unknown angular-momentum-loss mechanism(s) besides magnetic braking and gravitational radiation.

The Photometric Period and Variability of the Cataclysmic Variable V849 Herculis (PG 1633+115)

open access: yes, 2012
We report time-resolved photometry of the cataclysmic variable V849 Her, and measure a period of 0.1414 \pm 0.0030 days (3.394 \pm 0.072 hours). We also present photometry taken over several weeks in 2010 and 2011, as well as light curves from 1995 to ...

Hibernation Revived by Weak Magnetic Braking [PDF]

open access: yes, 2006
Cataclysmic variables undergo periodic nova explosions during which a finite mass of material is expelled on a short timescale. The system widens and, as a result, the mass-transfer rate drops.

Can the EU Move ‘Beyond GDP’?

open access: yesJCMS: Journal of Common Market Studies, Volume 64, Issue 2, Page 491-510, March 2026.
Abstract Since 2007, the European Union has devoted significant time and energy to the production and dissemination of new statistics designed to monitor social and environmental trends of various types. These initiatives have often been presented as part of a broader ‘beyond GDP agenda’, which challenges the centrality of economic growth, as measured ...

Nine New Cataclysmic Variable Stars with Negative Superhumps

open access: yesThe Astrophysical Journal
Negative superhumps (NSHs) are signals a few percent shorter than the orbital period of a binary star and are considered to originate from the reverse precession of the tilted disk.

Irradiation of the secondary star in cataclysmic variables [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1992
It is shown how the relative strength of the Na I doublet over the surface of the secondary star can be calculated from radial velocity curves obtained using the Na I absorption feature around 8190 A. The results for 11 dwarf novae and one magnetic cataclysmic binary system are presented.

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...
