El poder en el semipresidencialismo

open access: yesCuestiones Constitucionales Revista Mexicana de Derecho Constitucional, 2009
Si bien semipresidencialismo fue erigido doctrinalmente a partir de los estudios de Maurice Duverger en los setenta, los países que podían caber en esta categoría original (Finlandia, Islandia, Irlanda y Austria) parecen evolucionar en sentidos que colocan a esta tipología, más que en la cómoda posición "híbrida", como la particularidad exclusiva del ...

Mechanisms underlying the protective effects of San‐Bai decoction against UV radiation on the skin

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Combining conventional differential expression analysis with differential network analysis offers a promising strategy to uncover the mechanistic basis of the holistic benefits provided by herbal blends. Our findings demonstrated that San‐Bai decoction modulates multiple pathways—not only those related to skin pigmentation, such as ET‐1 signalling, but

Tariff: The Most Beautiful Word in the Dictionary?

open access: yesReview of International Economics, EarlyView.
ABSTRACT We consider the welfare impacts of US tariff policy at levels proposed by President Donald J. Trump. General‐equilibrium simulations under a widely used transparent one‐sector trade model reveal sizable US welfare losses. When we extend the model to include bilateral firm selection and high resolution input–output linkages, the US losses ...

There is No Consensus on Biological Sex. [PDF]

open access: yesEcol Lett
At this critical moment when misinformation about sex is being applied to policy globally, scientific clarification on the definition of biological sex is valuable. Here, we evaluate the primary approaches to defining sex and synthesise the active discourse to conclude that there is no current consensus on a definition of sex that is free of ...

Expanding the Methodological Repertoire in Institutional Ethnography: A Design Sociology Approach to Mapping and Visualizing Invisible Work

open access: yesCanadian Review of Sociology/Revue canadienne de sociologie, Volume 63, Issue 2, May 2026.
ABSTRACT This article presents a novel methodological approach in which institutional ethnography borrows from design sociology. Although mapping is a core component of institutional ethnography, previous research highlights opportunities to further develop mapping techniques as both an analytical tool and a means of presenting research findings ...

Simultaneous Imaging of Cu+ and Cu2+ in Neural Cells Using DNAzyme Probes Reveals Mechanistic Link Between Copper Redox Imbalance and Amyloid Pathology

open access: yesAngewandte Chemie, Volume 138, Issue 14, 27 March 2026.
We develop Cu+‐ and Cu2+‐specific DNAzyme fluorescent probes to visualize both copper redox states in living neurons. Aβ oligomers cause intracellular copper overload, triggering FDX1 dependent cuproptosis and generating ROS. This work links copper redox imbalance with Aβ pathology and offers a selective, sensitive way to monitor copper homeostasis in ...
