Evaluación de impactos socioambientales en proyectos urbanos: Revisión metodológica

CALIXTO MORALES, RUBEN DARIO

El estudio abordó la necesidad de evaluar los impactos socioambientales generados por proyectos urbanos, especialmente en el contexto de la fragmentación urbana. Se destacó la importancia de desarrollar metodologías efectivas para esta evaluación, considerando la complejidad y diversidad de los entornos urbanos contemp...

Mapping First Grader’s Numerical Development at Scale: Leveraging Cognitive Models in a Large-Scale Educational Assessment

SONNLEITNER, Philipp · Inostroza Fernández, Pamela · HORNUNG, Caroline

Large-scale assessments (LSAs) primarily support system-level monitoring, but their instructional diagnostic potential remains underused. Cognitive Diagnostic Models (CDMs) offer a promising avenue, though their application in LSAs poses theoretical and practical challenges. This study explores whether cognitive models...

Delays and detours during cancer diagnosis: a cross-sectional study on patient pathways and provider intervals in public healthcare networks of Chile, Colombia and Ecuador

Vázquez, María-Luisa · Eguiguren, Pamela · Mogollón-Pérez, Amparo-Susana · Peralta, Andrés · y 9 más

Abstract Background The longest delays in cancer diagnosis in Latin America occur between the first contact with health services and the confirmation of diagnosis (referred to as the provider interval), yet few studies have examined patient pathways to understand these delays. This study aims to analyze patient diagnos...

Family imprint reveals basin-wide patterns of Amazon forest embolism resistance

Tavares, Julia · Gloor, Emanuel · Silva, Thiago · Oliveira, Rafael · y 91 más

Abstract Amazon rainforests face intensifying water stress due to increases in vapour pressure deficit and changing hydrological regimes. Embolism resistance (Ψ 50 ) is a critical metric of tree survival under drought conditions, it is defined as a plant’s capacity to resist disruption of xylem water flow due to air bu...

Posesión predicativa en español: estrategias de codificación verbal

Alejandra Ortiz Villegas

This work presents a syntactic-semantic characterization of four verbs with possessive meaning: tener, poseer, pertenecer and contar (con). Its purpose is to demonstrate the syntactic coding of predicative possession in Spanish in these four verbs, understanding the notion of possession as a semantic relationship in wh...

Bounded powers of edge ideals: Gorenstein toric rings

Hibi, Takayuki · Fakhari, Seyed Amin Seyed

Let $S=K[x_1, \ldots,x_n]$ denote the polynomial ring in $n$ variables over a field $K$ and $I \subset S$ a monomial ideal. Given a vector $\mathfrak{c}\in\mathbb{N}^n$, the ideal $I_{\mathfrak{c}}$ is the ideal generated by those monomials belonging to $I$ whose exponent vectors are componentwise bounded above by $\ma...

Isomerization of α- and β-pinene epoxides over dendritic ZSM-5 zeolites

Mosquera, Carina · Gallego-Villada, Luis A. · Mediavilla, Marta · Cueto, Jennifer · y 3 más

The selective isomerization of α- and β-pinene epoxides was investigated using dendritic ZSM-5 zeolite catalystsunder mild reaction conditions using ethyl acetate as solvent at moderate temperatures (40–70 ◦C). The highlyinterconnected dendritic meso-macroporous structure and suitable Brønsted-to-Lewis acid sites balan...

The Milky Way Stellar Halo Is Twisted and Doubly Broken: Insights from DESI DR2 Milky Way Survey Observation

Songting Li · Wenting Wang · Sergey E. Koposov · João A. S. Amarante · y 44 más

Abstract Using K giants from the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI) Milky Way Survey, we measure the shape, orientation, radial profile, and density anisotropies of the Milky Way (MW) stellar halo over 8 kpc < r GC < 200 kpc. We identify a triaxial stellar halo (axis ratio 10:8...
