In consulting firms, organizational sustainability is often limited by the gap between stated institutional values and internal cultural practices, evidenced by non-participative leadership styles, hierarchical communication, and weak interdepartmental collaboration. This disconnect affects employee engagement and reduces organizational adaptability. The objective of this research was to analyze the impact of an organizational culture program on the sustainability of a consulting firm. The study adopted a mixed-methods approach, with a quasi-experimental pretest-posttest design with a non-equivalent control group. The population consisted of 28 employees, divided into an experimental group (n = 15) and a control group (n = 13). Data collection involved questionnaires on organizational norms and values, the dynamic profile of organizational culture, and qualitative techniques such as appreciative inquiry interviews, collective logs, and participant observation. Quantitative analysis was performed using the Mann-Whitney U test. The results showed that, after the intervention, the experimental group exhibited statistically significant improvements (p < 0.05) in internal communication, participative leadership, interdepartmental collaboration, structured feedback, and sense of belonging, compared to the control group. Qualitative findings confirmed positive changes in group cohesion, organizational commitment, and alignment of internal values. It is concluded that the implementation of an organizational culture program significantly contributes to strengthening organizational sustainability by promoting participatory, adaptive internal practices that are consistent with the company's strategic vision.

Floods represent the most frequent natural hazard, generating significant impacts on people as well as considerable economic and environmental losses worldwide. These events are particularly exacerbated by extreme climatic phenomena, such as the 2017 Coastal El Niño, the most intense in the past century, with the Piura region of Peru being the most affected. Flood susceptibility mapping (FSM) are essential for mitigating the negative impacts of floods through land-use planning, policy and plan formulation, and fostering community resilience for the sustainable occupation and use of floodplains. This study aimed to develop FSM in northern Peru, particularly in the Piura region, using a hybrid methodology integrating optical and radar remote sensing (RS), GIS, and machine learning (ML) techniques. Sentinel-1 data were used to map flood extent using the Normalized Difference Flood Index (NDFI), while flood susceptibility was modeled using ten topographic variables (derived from a DEM), the Normalized Difference Vegetation Index (NDVI), geology, and geomorphology; issues related to correlation and multicollinearity among topographic variables were addressed through Principal Component Analysis (PCA), selecting four principal components that explained 75.4% of the variance. Six FSMs were generated using Support Vector Machine (SVM) and Random Forest (RF), combined with different methods to estimate the quantitative relationship between variables and flood occurrence: Quantiles (q), Frequency Ratio (FR), and Weights of Evidence (WoE) (SVM-q, SVM-FR, SVM-WoE, RF-q, RF-FR, and RF-WoE). Model validation was performed using metrics such as the Area Under the ROC Curve (AUC), F1-score, and Accuracy, along with a cross-validation analysis. The results revealed that the RF ensemble model with WoE (RF-WoE) exhibited the best performance (AUC = 0.988 in training and >0.907 in validation), outperforming the SVM-based models; the SHAP analysis confirmed the significance of geology, geomorphology, and aspect in flood prediction. The resulting susceptibility maps identified the lower Piura River basin as the most vulnerable area, particularly during the 2017 Coastal El Niño event, due to morphological factors and inadequate land occupation. This study contributes to the field by demonstrating the effectiveness of a hybrid methodology that combines PCA, machine learning, and SHAP analysis, providing a more robust and interpretable approach to flood susceptibility mapping. Finally, the findings provide valuable inputs for local authorities, decision-makers, and organized communities to strengthen resilience, reduce vulnerability, and enhance preparedness against future floods, while also supporting the formulation of public policies and the integration of flood susceptibility into land-use planning for sustainable territorial management.

Introducción y objetivo: Los trastornos de la conducta alimentaria constituyen una problemática preocupante durante la etapa universitaria, ya que pueden comprometer el bienestar físico y psicológico de los estudiantes. Diversos factores pueden influir en la aparición de estos trastornos, entre los cuales destacan aquellos vinculados a la percepción personal y social del propio cuerpo. Por ello, el objetivo de la presente investigación fue determinar si la autoestima e imagen corporal predicen los trastornos de la conducta alimentaria en futuros docentes de educación física del Perú. Metodología: se llevó a cabo un estudio de enfoque cuantitativo, con un diseño no experimental, de tipo predictivo y transversal. La muestra estuvo compuesta por 209 estudiantes universitarios a quienes se aplicaron la Escala de Autoestima de Rosenberg, el Body Shape Questionnaire (BSQ-14) y el Eating Attitudes Test (EAT-26). Todos los instrumentos utilizados presentaron propiedades psicométricas adecuadas. Resultados: El modelo de regresión lineal múltiple fue estadísticamente significativo (F= 30.677, p<0.01), explicando el 22.9% de la varianza en los trastornos de la conducta alimentaria (R²= 0.229). Entre los predictores analizados, tanto la autoestima (β= -0.319, p<0.01) como la imagen corporal (β= -0.200, p<0.05) mostraron efectos negativos y significativos sobre la variable criterio. Además, los valores de tolerancia (0.531) y VIF (1.884) indicaron la ausencia de problemas de multicolinealidad, y el estadístico de Durbin-Watson (2.019) confirmó la independencia de los residuos. Conclusiones: la autoestima e imagen corporal predicen los trastornos de la conducta alimentaria en futuros docentes de educación física del Perú.

Introducción y objetivo: La satisfacción con la vida constituye un indicador del bienestar subjetivo en la etapa universitaria, influenciado por diversos factores individuales y contextuales.

Introduction: in recent years, emotional eating has received increasing attention due to its impact on health and well-being. Various studies have shown that emotions can influence eating patterns, leading individuals to eat in response to affective states rather than physiological needs. Objective: to determine whether depression, anxiety, and stress predict emotional eating in a sample of university students from the Peruvian Amazon. Methodology: a quantitative approach was adopted, using a non-experimental predictive design. The sample consisted of 436 university students who completed the Depression, Anxiety, and Stress Scale (DASS-21) and the Emotional Eating Questionnaire, both instruments with adequate psychometric properties. Results: the regression model was statistically significant (F= 75.692, p<0.05), explaining 34.5% of the variance in emotional eating (R²= 0.345). Among the variables assessed, de-pression (β= 0.153, p<0.05), anxiety (β= 0.227, p<0.05), and stress (β= 0.258, p<0.05) significantly predicted higher levels of emotional eating. Additionally, it was observed that women exhibited higher levels of depression, anxiety, stress, and emotional eating, while younger students showed higher levels of anxiety (p<0.05). On the other hand, no statistically significant differences were found based on employment status or relationship status, except for anxiety (p>0.05). Discussion: although some studies support these findings, further research is needed to corroborate and expand upon these results. Conclusions: depression, anxiety, and stress significantly predict emotional eating among university students from the Peruvian Amazon.

IntroductionInfant mortality is one of the most sensitive indicators of a country’s social and health development. Despite advances in public policies aimed at maternal and child health, significant challenges remain in sustainably reducing mortality rates among children under one year of age. The objective of this study was to analyze the impact of women’s literacy rate and educational level on infant mortality across the 24 departments and the constitutional province of Peru between 2001 and 2022.Materials and methodsData provided by the National Institute of Statistics and Informatics (INEI) were used, and a statistical analysis was conducted to explore the relationship between female literacy rate, educational attainment, and infant mortality across different regions of the country. A panel data model was employed, allowing for the assessment of both temporal variations and regional differences.ResultsThe findings reveal a significant and inverse relationship between women’s educational level— as measured by literacy rate and average years of schooling—and the infant mortality rate in Peru from 2001 to 2022. Higher levels of female education are associated with lower infant mortality, highlighting the central role of education as a determinant of child health. Furthermore, substantial regional disparities persist, particularly in rural and impoverished areas, where educational levels are lower and infant mortality rates are higher.Discussion and conclusionsThese results underscore the need for comprehensive public policies that improve both access to and the quality of education, strengthen infrastructure in health and education, and prioritize targeted interventions to reduce territorial gaps. A multisectoral and inclusive approach is essential to achieve sustainable improvements in child health indicators and promote social equity in the country.

Environmental problems represent one of the greatest threats to humanity, which is why environmental sustainability has become an issue of great relevance. In this context, sociodemographic factors are considered to play a fundamental role in the investigation of sustainable consumption behavior, particularly among residents of Indigenous communities. The present study aims to evaluate sustainable consumption behavior in relation to sociodemographic factors in indigenous communities in the Amazon region of Peru. Data were collected through a survey applied to a sample of 319 people selected by stratified probability sampling. The conceptual model and hypotheses were tested by multivariate analysis and structural equation modeling, using the principal component analysis method for factor extraction. As a result, the research revealed a positive connection between pro-environmental factors and sustainable behavioral intention. However, although sustainable behavioral intention was strong, it did not always translate directly into sustainable practices. Significant differences in gender, age, education, income, and occupation were identified as factors influencing sustainable practices. The results highlight the complexity of sociodemographic factors in the adoption of sustainable lifestyles in Indigenous communities. These findings provide a crucial basis for the development of tailored intervention strategies and the formulation of contextualized policies that promote sustainable consumption in these communities.

La conciencia ambiental turística constituye un eje fundamental para formar ciudadanos comprometidos con la sostenibilidad, especialmente en regiones de alta biodiversidad como Tambopata. Se buscó identificar la vocación turística ambiental, en estudiantes del 5to Año de Secundaria de la Institución Educativa Dos de Mayo. Se empleó un diseño no experimental, tipo aplicada, con niveles descriptivo y explicativo, de enfoque mixto que combinó encuestas, entrevistas y listas de cotejo a una muestra de 148 estudiantes, mediante análisis descriptivo, inferencial y codificación temática. La conciencia ambiental turística influye de manera positiva en la vocación de conservación, aunque evidenció un nivel moderado de conocimiento y percepciones variables sobre la calidad de los servicios turísticos y la participación comunitaria. Las actividades que combinan teoría y práctica, como visitas a atractivos naturales y talleres participativos, generan mayor impacto en la formación ambiental, mientras la participación irregular de los pobladores en la conservación refleja la necesidad de estrategias más consistentes. En conclusión, fortalecer la conciencia ambiental turística desde el ámbito escolar, mediante programas educativos integrales, campañas de sensibilización comunitaria y capacitación en buenas prácticas, es clave para consolidar en los jóvenes vocación de conservación hacia la sostenibilidad y preservación del patrimonio natural y cultural de Tambopata.

Los pueblos originarios de Madre de Dios ocupan este territorio desde hace más de 5,000 años. Hace siete siglos pasaron a una situación de autonomía relativa al llegar los Incas a través de las primeras vías terrestres que permitieron el acceso a lo que es actualmente el departamento de Madre de Dios. En el periodo republicano y especialmente en el siglo XX, se abrieron vías definitivas de penetración que cambiaron dramáticamente el panorama social y ambiental. El estudio es de tipo descriptivo, enfoque mixto con preponderancia cualitativa, diseño longitudinal, aplicándose la técnica de revisión documental y técnicas cualitativas complementado con datos e información cuantitativa. En la primera década del siglo XXI se concluyó la construcción de la Carretera Interoceánica Sur, cuyo tramo III atraviesa Madre de Dios. Los consecuentes impactos sociales y ambientales, resultantes de estos distintos momentos y visiones de desarrollo, han sido severos y son evaluados en el presente estudio.
