Leaf diseases, such as Black Sigatoka and Cordana, represent a growing threat to banana crops in Ecuador. These diseases spread rapidly, impacting both leaf and fruit quality. Early detection is crucial for effective control measures. Recently, deep learning has proven to be a powerful tool in agriculture, enabling more accurate analysis and identification of crop diseases. This study applied the CRISP-DM methodology, consisting of six phases: business understanding, data understanding, data preparation, modeling, evaluation, and deployment. A dataset of 900 banana leaf images was collected—300 of Black Sigatoka, 300 of Cordana, and 300 of healthy leaves. Three pre-trained models (EfficientNetB0, ResNet50, and VGG19) were trained on this dataset. To improve performance, data augmentation techniques were applied using TensorFlow Keras’s ImageDataGenerator class, expanding the dataset to 9000 images. Due to the high computational demands of ResNet50 and VGG19, training was performed with EfficientNetB0. The models—EfficientNetB0, ResNet50, and VGG19—demonstrated the ability to identify leaf diseases in bananas, with accuracies of 88.33%, 88.90%, and 87.22%, respectively. The data augmentation increased the performance of EfficientNetB0 to 87.83%, but did not significantly improve its accuracy. These findings highlight the value of deep learning techniques for early disease detection in banana crops, enhancing diagnostic accuracy and efficiency.

Background: While many health care providers have shifted toward telehealth services in response to the COVID-19 pandemic, little is known about the perception and acceptance of such services, particularly among vulnerable populations. Veterans, who are at increased risk of physical and mental health needs, may benefit from the use and availability of telehealth services. Materials and Methods: Cross sectional survey data related to telehealth use, satisfaction, and access were collected through an online survey. Participants from previous research studies and veterans receiving care at a national veteran behavioral health organization were invited to participate. Results: A total of 404 veterans participated. Before the pandemic, many veterans had never used telehealth for physical (72%) or mental (76%) health care. Since the start of the pandemic, 62% of participants reported they received some care through telehealth services. Most participants found telehealth valuable and helpful (82%), indicated the technology was well explained (77%), and felt that issues were resolved quickly and easily (67%). Access to care was limited among participants who utilize massage therapy (64%), dental care (53%), routine checkups (50%), acupuncture (50%), and physical therapy (48%). Discussion: These findings showed an increase in the use of telehealth services and overwhelming satisfaction among veterans. Despite this, some veterans indicated barriers to receiving physical and mental health care. Conclusions: This provides an opportunity to expand the use of telehealth services to meet the health care needs of veterans. Barriers to care should be addressed to minimize the impact on the well-being of veterans.

Significant gaps remain in our understanding of how minority stress patterns health outcomes for adults at the intersection of ethnicity/ race and sexual orientation. In particular, little is known about how cumulative cortisol (measured via hair cortisol concentration as an indicator of chronic stress; HCC) and depressive symptoms are related to holding an intersectional minoritized identity (e.g., sexual minority people of color; SM-POC) and experiencing intersectional discrimination (e.g., heterosexism and racism). The current study examined the relationship between intersectional identity or discrimination and HCC or depressive symptoms. Participants were (N = 69) low-income, predominantly sexual minority and people of color in the Greater Los Angeles area. Participants completed self-report measures and provided a hair sample for cortisol assay. Intersectional identity was not associated with greater HCC or depressive symptoms. However, differences in HCC emerged based on discrimination type (F (2, 66) = 3.74, p = .03, η²= .10). Participants who reported intersectional heterosexism and racism had greater HCC concentrations (M = 30.71, SD = 29.71) than did participants who reported only a single type of discrimination (i.e., racism only or heterosexism only; M = 15.35, SD = 2.60, p = .03, 95 % CI = [2.01, 28.71]), or than participants who reported neither types (M = 12.40, SD = 16.11, p = .01, 95 % CI [4.85, 31.76]). There were no differences in depressive symptoms by discrimination type. These results provide initial empirical support to largely theoretical arguments about how to investigate mechanisms underlying disparities to understand why and how minority stress is patterned. Findings showing associations between intersectional discrimination and HCC, but not depressive symptoms, provide potential support for theories about examining allostatic load markers to identify stress-related etiological mechanisms linked to health disparities among minoritized populations.

In the present day, many risk factors affect the continuity of a business. However, this situation produces a conducive atmosphere to approach alternatives that relieve this situation for organizations. Within these alternatives, environmental sustainability (ES) and information technologies governance (IT governance or ITG) stand out. Both alternatives allow organizations to address intrinsically common issues such as strategic alignment, generation of value, mechanisms for performance improvement, risk management and resource management. This article focuses on the fusion of both alternatives, determining to what extent current ITG models consider ES issues. With this purpose, the strategy followed was firstly to identify the relevant factors of ES present in the main approaches of the domain (ISO14001, GRI G4, EMAS, SGE21 and ISO26000). As a result, we identified 27 activities and 103 sub-activities of ES. Next, as the second main objective, we determined which of those factors are present in the main current ITG approaches (COBIT5, ISO38500 and WEILL & ROSS). Finally, we concluded through a quantitative study that COBIT5 is the most sustainable (i.e., the one that incorporates more ES issues) ITG approach.

En la toma de decisiones de Tecnologías de Información (TI), es fundamental el apoyo de los diferentes tipos de marcos para el gobierno y gestión de TI de la misma empresa. Existen dos principales principios de gobierno que pueden aportar significativamente al buen desenvolvimiento de una empresa: conformidad y rendimiento. Es por esto, que el presente artículo presenta un estudio exploratorio de los soportes técnicos establecidos en los departamentos de tecnología de la información de la ciudad de Santa Rosa, provincia de El Oro en el año 2015-2016, en el cual se pretende verificar la aplicación de gobierno de las TI en las empresas seleccionadas. Los resultados que se obtuvieron evidencian claramente la escaza incorporación de gobierno de TI dentro de las empresas evaluadas, por lo que se recomienda su incorporación inmediata como una medida para garantizar servicios de calidad a sus clientes. AbstractIn the decision making of Information Technology (IT), the support of different types of frameworks for the government and IT management of the same company is fundamental. There are two main principles of government that can contribute significantly to the good performance development of a company: compliance and performance. That is why this article presents an exploratory study of the technical supports established in the information technology departments of the city of Santa Rosa, province of El Oro in the year 2015-2016, in which it is tried to verify the application of IT Governance in selected companies. The results obtained clearly evidenced the scarce incorporation of IT governance within the evaluated companies, therefore it is recommended its immediate incorporation as a measure to guarantee quality services to its clients.
