Sensitivity and Specificity of the Newborn Infant Parasympathetic Evaluation Index in Pain Assessment of Very Low Birth Weight Infants

Objective This article describes the results of a study investigating the sensitivity and specificity of the Newborn Infant Parasympathetic Evaluation (NIPE) index for detecting the physiological changes resulting from nociception in painful procedures in very low birth weight (VLBW) infants. Study Design A prospective observational study was carried on of 44 newborns at 23 to 32 weeks' gestational age. The sensitivity and specificity of the NIPE index are analyzed using a receiver operating characteristic curve. Most of the painful procedures performed were skin-lancing and venipunctures. Nonpainful procedures consist of no intervention, with an interval of at least 1 hour with painful procedures in each newborn. Results The accuracy of the NIPE index to diagnose mild nociceptive stimulation in VLBW newborns is 73.2%. Conclusion The NIPE index is a useful technique for assessing nociceptive stimulation in newborns, presenting less observer-dependent variability than other pain assessment scales

Spanish Version of a Scale to Evaluate the Quality of Work Life in Teachers: An Adaptation of Walton’s QWL Model in the Peruvian Context

Workers’ job satisfaction benefits the organization, which constitutes a competitive advantage. This is why the Quality of Work Life (QoWL) study has gained relevance in recent years. For this reason, various scales have been developed to evaluate this organizational variable constantly. However, to date, there is no evidence in the scientific literature of a Spanish version that evaluates the validity and reliability of these scales in a Peruvian context. Thus, this study aimed to translate into Spanish and adapt and analyze the validity and reliability of a scale to assess the quality of work life in Peruvian teachers based on Walton’s model. For this purpose, 457 regular basic education teachers from a private educational network located in the three regions of Peru were surveyed. The analyses used the Structural Equation Model (SEM) with the AMOS 24 statistical software. Confirmatory Factor Analysis provided an excellent fit model of eight factors and 31 elements (CMIN/DF = 2.351; CFI = 0.955; SRMR = 0.062; RMSEA = 0.054; Pclose = 0.052). It also demonstrated good internal consistency (α = between 0.806 and 0.938; CR = between 0.824 and 0.939; AVE = between 0.547 and 0.794). These results contribute to the study of QoWL in Peru

Influence of COVID-19 on Environmental Awareness, Sustainable Consumption, and Social Responsibility in Latin American Countries

This article aims to investigate the effect that COVID-19 has on environmental awareness, sustainable consumption, and consumer social responsibility. Although some recent research focused on this phenomenon, there are still no studies applied to Latin American consumers. In this study, the data comes from 1624 responses from Latin American consumers who also represent different generations, equitably distributed in 400 from Chile (24.6%), 421 from Colombia (25.9%), 401 from Mexico (24.7%), and 402 from Peru (24.8%). Data were collected through self-administered questionnaires using an online survey via Google Forms through email and social networks (Facebook, LinkedIn, Instagram, and WhatsApp) from July 2021 to September 2021. This study uses a quantitative methodology using a structural equations model (SEM) to examine the cause–effect relationships of the explanatory model of this study. The main findings indicate that consumers from these countries declare that their behaviors have become ecologically and socially responsible. In addition, these respondents indicated that they had increased their interest in sustainable consumption and in ac quiring environmentally friendly products to reduce waste and negative impacts on the environment derived from consumption. Based on the results, this research provides useful information to change or re-direct the communication and strategies of governments, brands, organizations, and society to promote actions and behaviors that help reduce the negative impact on the environment derived from consumption in a Latin American market. Managerial implications are provided

Student Evaluation of Teachers’ Effectiveness (SETE) scale: translation, cross-cultural adaptation and psychometric properties in a Latin American sample

Introduction: Teacher effectiveness is a burgeoning field. Those responsible for educational policies seem increasingly committed to this fact, since it is one of the most important factors that influence the success of a university student; for this reason, the study of this topic has gained relevance in recent years. Therefore, an instrument with adequate psychometric properties is needed to measure this construct in Spanish-speaking countries. Objective: The study had the purpose of translating, adapting, and evaluating the internal structure, providing evidence of reliability and validity of the Student Evaluation of Teachers’ Effectiveness (SETE) Scale in a Latin American sample. Methods: An instrumental study was carried out and through convenience sampling, data were collected from 1,000 university students from South America belonging to a private educational network. The participants were between 18 and 40 years old (M = 21.25, SD = 2.99). Analyzes used Structural Equation Modeling (SEM) with AMOS 24 statistical software. Results: Confirmatory Factor Analysis provided a 4-factor, 28-item fit model (CMIN/DF = 4.359; CFI = 0.956; SRMR = 0.030; RMSEA = 0.058). The results demonstrated good internal consistency (α = between 0.927 and 0.961; CR = between 0.927 and 0.962; AVE = between 0.646 and 0.799). Evidence of validity and reliability was obtained for the total sample. Discussion: This adaptation and validation of the SETE scale makes it a valid, useful, reliable, and necessary tool that can be considered to evaluate teachers’ effectiveness from the perspective of university students

Allogenic controls on the cyclicity on the continental sedimentation in the Guadix Basin (Betic Cordillera, Spain) throughout Pliocene and Pleistocene: state of the art

La Cuenca de Guadix (Cordillera Bética, S de España) constituye un escenario ideal para el estudio de los procesos auto- y alogénicos que influyen en la sedimentación continental en cuencas hidrológicamente cerradas. La extensión y continuidad lateral y vertical de los afloramientos y la presencia de numerosos yacimientos arqueológicos y paleontológicos en la zona han permitido interpretar cómo evolucionó la cuenca durante los últimos 4 Ma, y qué factores influyeron en dicha evolución. Estos estudios cobran una mayor importancia al permitir la caracterización de los paleoambientes que constituyeron el hábitat de los primeros pobladores de Europa. En el presente trabajo se muestra una síntesis de los estudios estratigráficos, sedimentológicos, petrológicos y paleoclimáticos más destacados desarrollados en los últimos años en la Cuenca de Guadix y los resultados más novedosos respecto a los controles alogénicos que determinaron la sedimentación continental en la cuenca.The Guadix Basin (Betic Cordillera, S Spain) is the ideal scenario to study the auto- and allogenic processes controlling continental sedimentation in hydrologically closed-basins. The extension and the lateral and vertical continuity of the outcrops, together with abundant archaeological and palaeontological sites in the area, have allowed the interpretation of the evolution of the basin throughout the last 4 Ma and the factors controlling it. These studies become much more important due to their relation to the characterisation of palaeoenvironments inhabited by the first European hominins. In this work, we present a synthesis of the most significative stratigraphical, sedimentological, petrological and palaeoclimatic studies developed in the Guadix Basin in the last decade, and updated results regarding the allogenic factors that controlled the continental sedimentation in the basin.El presente estudio ha sido financiado por el Proyecto CGL2009-07830/BTE (MICINN-FEDER), los Grupos de Investigación RNM-369 y RNM-200 del Plan Andaluz de Investigación y por el ProyectoAHOB-3 (Leverhulme Trust Foundation)

Nanoflowers Versus Magnetosomes: Comparison Between Two Promising Candidates for Magnetic Hyperthermia Therapy

Magnetic Fluid Hyperthermia mediated by iron oxide nanoparticles is one of the most promising therapies for cancer treatment. Among the different candidates, magnetite and maghemite nanoparticles have revealed to be some of the most promising candidates due to both their performance and their biocompatibility. Nonetheless, up to date, the literature comparing the heating ef ciency of magnetite and maghemite nanoparticles of similar size is scarce. To ll this gap, here we provide a comparison between commercial Synomag Nano owers (pure maghemite) and bacterial magnetosomes (pure magnetite) synthesized by the magnetotactic bacterium Magnetospirillum gryphiswaldense of hDi 40 45 nm. Both types of nanoparticles exhibit a high degree of crystallinity and an excellent degree of chemical purity and stability. The structural and magnetic properties in both nanoparticle ensembles have been studied by means of X Ray Diffraction, Transmission Electron Microscopy, X Ray Absorption Spectroscopy, and SQUID magnetometry. The heating ef ciency has been analyzed in both systems using AC magnetometry at several eld amplitudes (0 88 mT) and frequencies (130, 300, and 530 kHz).This work was supported in part by the Spanish "Ministerio de Ciencia, Investigación y Universidades'' under Project MAT2017-83631-C3-R, and in part by the Nanotechnology in Translational Hyperthermia (HIPERNANO) under Grant RED2018-102626-T.

Exploring the Different Degrees of Magnetic Disorder in TbxR1−xCu2 Nanoparticle Alloys

Recently, potential technological interest has been revealed for the production of magnetocaloric alloys using Rare-Earth intermetallics. In this work, three series of TbxR1−xCu2 (R ≡ Gd, La, Y) alloys have been produced in bulk and nanoparticle sizes via arc melting and high energy ball milling. Rietveld refinements of the X-ray and Neutron diffraction patterns indicate that the crystalline structure in all alloys is consistent with TbCu2 orthorhombic Imma bulk crystalline structure. The analyses of the DC-magnetisation (MDC) and AC-susceptibility (χAC) show that three distinct degrees of disorder have been achieved by the combination of both the Tb3+ replacement (dilution) and the nanoscaling. These disordered states are characterised by transitions which are evident to MDC, χAC and specific heat. There exists an evolution from the most ordered Superantiferromagnetic arrangement of the Tb0.5La0.5Cu2 NPs with Néel temperature, TN∼ 27 K, and freezing temperature, Tf∼ 7 K, to the less ordered weakly interacting Superparamagnetism of the Tb0.1Y0.9Cu2 nanoparticles (TN absent, and TB∼ 3 K). The Super Spin Glass Tb0.5Gd0.5Cu2 nanoparticles (TN absent, and Tf∼ 20 K) are considered an intermediate disposition in between those two extremes, according to their enhanced random-bond contribution to frustration.This work has been supported by the Spanish MAT2017-83631-C3-R grant.
