Structural insights and comparative electrocatalytic performance of citric acid-functionalized Luffa aegyptiaca and Pt-Pd/MWCNT-Luffa composites for the degradation of acetaminophen in aqueous media

Emerging contaminants, such as acetaminophen, pose a critical threat to aquatic ecosystems and human health due to their persistence in water and the difficulty of their removal using conventional methods. In this work, Luffa aegyptiaca biomass was valorized via citric acid funct...

From an estate to urban districts. Invasions, expropriations, and sales in the transformation of San Juan (Lima, 1940–2020)

This study, within the context of the urban transformation of the city of Lima (Peru) between the twentieth century and the present, investigates an agricultural estate (San Juan) that became incorporated into Lima’s urban area, now part of the current districts of San Juan de Mi...

The response of multinational and international organisations to resilience and sustainability in Latin America and the Caribbean: future directions

Purpose This study aims to examine the theoretical foundations of resilience and sustainability in relation to multinational enterprises and international organisations operating in Latin America and the Caribbean (LAC). It provides an understanding of how resilience and sustaina...

Beyond Words: Arts-Based Research Methods as an Intercultural Bridge for Work With Indigenous Women in Peru

Kinetically moderated reprotonation reconstructs aramid nanofiber hydrogen-bond networks for high-performance thermal management and EMI shielding composite films

Flexible electronic devices urgently require lightweight multifunctional films that can dissipate heat, suppress electromagnetic interference (EMI), and retain mechanical reliability under repeated deformation. However, filler-rich polymer composites often improve thermal/electri...

Effect of Altitude on Gasoline Combustion Efficiency in Light-Duty Vehicles: Evidence from Andean Corridors (0–4000 m a.s.l.)

Reduced air density at altitude challenges spark-ignition combustion in light-duty vehicles, particularly in Andean countries where fleets operate between sea level and over 4000 m a.s.l. We quantified the effect of altitude on gasoline combustion efficiency and pollutant formati...

Influence of the internal air temperature on properties of wood-plastic composites processed by rotational molding

In the processing of wood-plastic composites ( WPC ) by rotational molding, thermal decomposition of wood can occur due to the high temperatures of the process. However, it can be avoided by controlling the peak internal air temperature ( PIAT ). In this perspective, the main pur...

Academic Engagement and Perceived Employability in Higher Education: A Systematic Review of Associations, Mechanisms, and Implications for Employability Development and Sustainable Career Research

Academic engagement and perceived employability are increasingly relevant to how higher education prepares students for changing labor markets, yet their empirical relationship remains theoretically and methodologically fragmented. This systematic review synthesized primary studi...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...

Factors Associated with the Dimensions of Compassion Fatigue in Nursing: The Role of Empathy and the Work Environment

Background/Objectives: Compassion fatigue can affect nursing professionals exposed to demanding clinical environments and may be influenced by individual and work-related factors. The objective of this study was to analyze the factors associated with the compassion and fatigue/ex...

Predictors of dengue vaccination intention among adults in selected endemic areas of Peru: a PLS-SEM analysis

Background Dengue remains a major public health challenge in endemic settings. Evidence on the psychosocial predictors of dengue vaccination intention remains limited in Peru. This study aimed to identify predictors of dengue vaccination intention among adults in selected endemic...

CEO political ideology and personality as determinants of firm performance in an emerging economy

Purpose This study aims to examine whether CEO personality traits are associated with political ideology and whether CEO ideology is directly associated with firm performance in an emerging-economy context. Design/methodology/approach This study uses primary survey data from 205...

Festivities at the edge of data: an interdisciplinary study of Andean festivals in wikidata

This article examines how two Andean ritual traditions, Qoyllur Rit’i and the Virgen del Carmen of Paucartambo, are structurally represented within Wikidata. Using a compact knowledge graph extracted from Wikidata through ritual, geographic, heritage, and classificatory relations...

Gender differences in STEM careers: autonomy-supportive climate, metacognitive strategies, self-efficacy, and their association with academic performance and satisfaction

STEM education has always played a central role in scientific and technological advancement; however, recent years have seen heightened attention to the academic challenges faced by students in STEM programs. An important one is that in a predominantly male environment like that...

Contribution of research on mentoring, leadership and social responsibility: a bibliometric and visualization analysis

This study examines the evolution and intellectual structure of research on mentoring and its connections with leadership and social responsibility through bibliometric analysis. Drawing on 291 publications indexed in Scopus, the study analyses global research trends, influential...

How Norms Depend on the Presence and Status of Observers: The Relational Contingency of Everyday Behaviors in 90 Societies

Norms are fundamental to social life, but basic questions about how they are affected by social context remain. Specifically, how do normative constraints depend on the presence and status of observers, and how do such relational contingencies vary across cultures? Using data fro...

On Goldbach numbers in short intervals

Assuming the Riemann Hypothesis, we prove that for all $$x\geqslant 2$$ , there exists at least one even integer within the interval $$(x, x+123\log ^2x]$$ , that can be expressed as the sum of two primes. This result is an improvement over the recent work of Cully-Hugill and Dud...

Real-World Emission Factors for Andean Light-Duty Vehicles Based on a PSVm10-Validated Driving Cycle Across 0–4000 m Altitude

Emission inventories for high-altitude Andean cities rely on sea-level certification cycles that misrepresent real-world combustion conditions. This study derives altitude-resolved emission factors (EFs) for light-duty gasoline vehicles across 0–4000 m a.s.l. in Ecuador using the...

Experimental modal-based damage evaluation of masonry cross-vaults under quasi-static and dynamic cyclic loading

Masonry cross-vaults are double-curvature structural systems widely employed in historic churches and monumental buildings, which exhibit a pronounced vulnerability to seismic actions owing to the mechanical characteristics of their constituent materials. In such structures, diag...
