Resilience factors and coping as predictors of academic performance of the students in private universities
Predecir el rendimiento académico en estudiantes universitarios peruanos es una
garantía para cumplir las exigencias de licenciamiento y acreditación. Se realiza un
diseño transversal, comparativo y explicativo para establecer los factores de
resiliencia y afrontamiento que predicen el rendimiento académico, en dos muestras
probabilísticas estratificadas de universidades privadas de Lima. El RESI-, CAE,
Smilkstein, CP-LS y estimadores DWLS, GLS, demostraron que el modelo predictivo
de resiliencia y promedio ponderado tienen efecto en la percepción de rendimiento
académico y un efecto mínimo en el promedio ponderado. Ambos factores predicen
de manera directa, indirecta y relacional el rendimiento académico. Destacan los
factores confianza en sí mismo, capacidad social, estrategias de autofocalización
emocional abierta, exposición emocional abierta y apoyo familiar social como
predictores relevantes en expectativa de logro, aprendizaje percibido y satisfacción
global. El funcionamiento familiar, es un predictor indirecto a través de la resiliencia
del rendimiento académico. Factores de afrontamiento activo, predicen mejor la
percepción del rendimiento que factores de protección y riesgo. Muestras
homogéneas grandes con valor psicométrico pueden mejorar los modelos
predictivos, identificar perfiles, diseñar estudios causales, desarrollar programas de
aprendizaje de talento y estrategias activas que mejorarían la calidad del aprendizaje
universitario.Predicting academic performance in Peruvian university students is a guarantee to
meet licensing and accreditation requirements. A transversal, comparative and
explanatory (predictive) design was used to establish the resilience and coping
factors that predict academic performance, in two stratified probabilistic samples
from private universities in Lima. The RESI-, CAE, Smilkstein, CP-LS and DWLS
estimators, GLS, showed that the predictive model of resilience and weighted average
have an effect on the perception of academic performance and a minimal effect on the
weighted average. Both factors predict academic performance directly, indirectly and
relationally. The self-confidence factor, social capacity, open emotional self-targeting
strategies, open emotional exposure and social family support are highlighted as
relevant predictors in expectation of achievement, perceived learning and overall
satisfaction. Family functioning is an indirect predictor through the resilience of
academic performance. Factors of active coping better predict the perception of
performance than protection and risk factors. Large homogeneous samples with
psychometric value can improve predictive models, identify profiles, design causal
studies, develop talent learning programs and active strategies that would improve
the quality of university learnin
Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries
Background: Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods: The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results: A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion: Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)

Aportaciones al diseño de circuitos de altas prestaciones en tecnologías CMOS: la familia lógica FTL-CMOS
Programa de doctorado: Ingeniería de Telecomunicación avanzada.En esta tesis se propone el estudio de una nueva familia lógica CMOS utilizando el concepto de evaluación anticipada (feedthrough) presentada recientemente en diversas referencias. A lo largo de esta tesis se ha aplicado el concepto FTL al diseño e implementación de sumadores RCA en tecnologías CMOS. Los resultados presentados resultan concluyentes: FTL consigue mejoras significativas tanto en retardo como en eficiencia energética cuando se compara con las familias lógicas convencionales (CMOS, nMOS y dominó). Es más, los sumadores RCA FTL presentan mejores prestaciones en término de velocidad y eficiencia energética incluso cuando se comparan con sumadores de altas prestaciones CSA multinivel en tecnologías CMOS

Low power and high performance arithmetic circuits in feedthrough CMOS logic family for low power applications
This paper presents the design of low power high performance arithmetic circuits using the feedthrough logic (FTL) 1 concept. FTL is ideally suited for the circuit design where the critical path is made of a large cascade of inverting gates. Its high fanout and high switching frequencies are due to both lower delay and dynamic power consumption. Low power FTL arithmetic circuits provides for smaller propagation delay time (2.6 times), lower energy consumption (31%), and similar combined delay, power consumption, and active area product, when compared with the standard CMOS technologies.3073008ESC
