Plasma of COVID-19 patients contains a strong metabolomic/lipoproteomic signature, revealed by the NMR analysis of a cohort of >500 patients sampled during various waves of COVID-19 infection, corresponding to the spread of different variants, and having different vaccination status. This composite signature highlights common traits of the SARS-CoV-2 infection. The most dysregulated molecules display concentration trends that scale with disease severity and might serve as prognostic markers for fatal events. Metabolomics evidence is then used as input data for a sex-specific multi-organ metabolic model. This reconstruction provides a comprehensive view of the impact of COVID-19 on the entire human metabolism. The human (male and female) metabolic network is strongly impacted by the disease to an extent dictated by its severity. A marked metabolic reprogramming at the level of many organs indicates an increase in the generic energetic demand of the organism following infection. Sex-specific modulation of immune response is also suggested.
Attracting Grade "A" Students in Library and Information Science in Nigeria
Authors: Kuku David
Published: November 2023

Library and Information Science schools in Nigeria are today situated in serious competitive environments characterized by challenges which they must cope with in order to survive, advance and become more relevant in the scheme of things.The extent to which they are willing and able to overcome these challenges will go a long way in determining the extent to which they can attract quality candidates for admission into their programmes. It is natural that employers of labour would prefer to hire individuals who would add value to their organizations. This expectation is even more pertinent for the library and information professionals in this digital era where ICTs have come to bear in all facets of library and information work as organizations are gradually becoming knowledge based so as to maintain a niche over others in the global economy. in this study, the researcher found out that,Library and information schools need to actively engage in marketing and outreach activities. This can include participating in education fairs, conferences, and open house sessions. Additionally, social media platforms and targeted advertisements can be used to reach potential students.Foster partnerships with libraries and information centers: Library and information schools should forge partnerships with libraries and information centers, both within Nigeria and internationally. These partnerships can provide research opportunities, access to resources, and potential employment options for students after graduation
HISTORICAL RETAINING WALLS MONITORING: A CASE STUDY OF DEBOSQUETTE WALL OF KYIV-PECHERSK LAVRA
Authors: Shults Roman , Bilous Mykola , Khailak Andrii
Published: November 2023

Geospatial monitoring of historic buildings has a valuable meaning for their restoration and preservation measures. The preparation and accomplishment of such monitoring have their features and cannot be standardized. Therefore, in each particular case, monitoring is carried out for specific requirements and conditions. The paper presents the results of geospatial monitoring for a part of the UNESCO object Kyiv-Pechersk Lavra. The primary subject of geospatial monitoring is a retaining wall known as the Debosquette Wall. The wall was built in the XVIII century and underwent restoration in 2014. A geospatial monitoring system has been established to prevent undesirable damage and displacements. Assigning the necessary observation accuracy for such a complex object is difficult. In the paper, the modern approach to observation accuracy calculation has been suggested and studied. The approach is based on the application of structural mechanics principles. The structural analysis of the Debosquette Wall has been accomplished. The output of the analysis was applied to calculate the required observation accuracy. The geospatial network and monitoring scheme were developed based on the calculated accuracy. The monitoring proceeded for half a year in 2012-2013, was interrupted for one year, and kept on in 2015. The primary stress was made on the horizontal displacements in that these displacements are the primary threats to the wall stability. The in-depth analysis of the monitoring results has been accomplished. It was found that the displacements have stayed within the allowable values. The developed monitoring approach is recommended for similar projects.

Published: November 2023

The accuracy of artificial intelligence techniques in estimating air quality is contingent upon a multitude of influencing factors. Unlike our previous study that examined PM2.5 over whole Europe using unbalanced spatial-temporal data, the focus of this study was on estimating PM2.5 specifically over the Czech Republic using more balanced dataset to train and evaluate the model. Moreover, the spatial autocorrelation between the ground-based station was taken into consideration while building the model. The feature importance while developing the Extra Trees model revealed that spatial autocorrelation had greater significance in comparison to commonly used inputs such as elevation and NDVI. We found that R2 of the 10-CV for the new model was 16% higher than the previous one. R2 reached 0.85 when predicting unseen data in new locations. The developed spatiotemporal model was employed to generate comprehensive daily maps covering the entire study area throughout the 2018–2020 years. The temporal analysis showed that the levels of PM2.5 exceeded recommended limits of 20 µg/m3 during the year 2018 in many regions. The eastern part of the country suffered from the highest concentrations especially over Zlín and Moravian-Silesian Regions where in the 2018 winter, the values reached risky average concentrations of 30 µg/m3 and 35 µg/m3 respectively. Air quality improved during the next two years in all regions reaching promising levels in 2020 where almost all regions had average concentrations less than 20 µg/m3. The generated dataset will be available for other future air quality studies.
teoría del conflicto social de John Dewey
Authors: Mattarollo Livio
Published: November 2023

Durante las primeras décadas del siglo XX el filósofo pragmatista John Dewey perfila una filosofía social que incluye una teoría del conflicto social. Estas ideas encuentran su mejor desarrollo en las conferencias dictadas en China (1919-1921). En este marco, el presente artículo busca (i) introducir el “tercer tipo” de filosofía social propuesto por Dewey, abocada a resolver problemas concretos mediante la convergencia entre método científico y propósitos morales; (ii) reconstruir la teoría del conflicto social, teoría que presta especial atención a los conflictos de intereses y de principios de organización social entre grupos determinados; (iii) comparar el estándar normativo de evaluación del desarrollo social presentado en las conferencias con la noción de democracia como “experiencia conjunta comunicada” planteada por Dewey en Democracia y Educación (1916); y finalmente (iv) sopesar los aportes de la teoría del conflicto social al pensamiento filosófico-político del pragmatista. Desde allí se afirma que el estándar normativo de las conferencias es consistente con el enfoque conceptual en curso y que la teoría del conflicto social, aun cuando fuera posteriormente abandonada, fortalece la perspectiva deweyana pues incorpora una dimensión de análisis indispensable para todo tratamiento descriptivo-normativo de la sociedad y ofrece herramientas promisorias para abordar problemas sociales contemporáneos.
Enhancing Empathy in Nursing Education: A Feasibility and Usability Study of Virtual Reality-based Training for Dementia Care
Authors:   Al al-Bayt University, Abdalrahim Asem
Published: November 2023

Background: Virtual reality (VR) is recognized as a versatile training tool across various domains, including healthcare. In Jordan, dementia is a significant public health concern, accounting for 5.17% of all recorded deaths. Given the complex nature of dementia care, preparing nursing students is crucial. Purpose: This paper explores the feasibility and effectiveness of VR-based empathy training for nursing students, with a growing global interest in VR training applications, despite the need for further study of VR acceptability in the Jordanian context. Methods: This mixed-methods study included 71 nursing students in a psychiatric course at a university in Jordan. Feasibility was assessed through recruitment, retention, adherence, data completion, and implementation fidelity. Pre- and post-intervention assessments measured empathy levels. Thematic analysis of participant feedback provided insights into usability. Results: Recruitment and retention rates were excellent, with a 100% participation rate and 100% retention. The intervention demonstrated a statistically significant enhancement in empathy scores following the program (M_pre = 50.44, SD_pre = 9.24; M_post = 65.17, SD_post = 8.53), t (71) = -23.89, p < 0.001. The thematic analysis highlighted the importance of a user-friendly interface, a supportive learning environment, and engaging content. Conclusion: This study highlights the potential of VR-based training to enhance empathy among nursing students in the context of dementia care. The robust feasibility outcomes and positive user experiences suggest that VR technology can be a valuable addition to nursing curricula, ultimately benefiting patient care and the nursing workforce. Implications for Nursing: Integrating VR into nursing education presents the potential for elevating empathy in nursing students, notably within dementia care. This innovative approach equips prospective healthcare providers with vital skills for delivering more compassionate patient care. Keywords: Dementia, Nursing education, Empathy, Virtual reality, Feasibility studies, Patient-centered care.
Equisetum ×meridionale (Milde) Chiov. – a new hybrid taxon in the flora of Poland
Authors: Tlałka Dariusz , Sliwinska Elwira , Kruk Jerzy
Published: November 2023

A new hybrid within the Hippochaete subgenus of Equisetum genus, Equisetum ×meridionale (Milde) Chiov. was discovered in Poland during the research conducted in 2022 at two locations in Kotlina Żywiecka (the Żywiec Basin) and Beskid Wyspowy (Island Beskids – Western Beskids) in the anthropogenic habitats in close proximity to Equisetum ramosis-simum. The identity of the hybrid was unequivocally confirmed by macro-morphological observations, microscopic analysis and flow cytometry. The most pronounced macroscopic characteristics of the hybrid were the intermediate size of the shoots and leaf sheaths, which are black with long black teeth. The microscopic observations revealed that the hybrid has silica tubercles in the form of cross-bands, similarly as in the case of E. ramosissimum, but not in the form of two rows as in the case of E. variegatum. The measurements of the nuclear DNA content (2C values) revealed that the putative hybrid had a nuclear DNA content intermediate to that of the parental species, i.e. E. ramosissimum (56.13 pg) and E. variegatum (63.80 pg) obtained in the present studies and within the values previously reported for E. ×meridionale (60.7-61.2 pg).

Cancer patients should be concerned about depression, which can negatively impact their mental health. To develop efficient therapies, it is essential to comprehend the connection between cancer and depression. This study used neuroimaging to investigate the use of mediator-deuterium acupuncture (MDA) for people with cancer-induced depression and its effects on brain regions associated with depression. Resting-state functional magnetic resonance imaging and neurocognitive testing were conducted on the participants, and statistical package for the social sciences was utilized to analyze the behavioral data. Clinical and theoretical data were analyzed to evaluate acupuncture’s effectiveness against gynecological cancer. In the research, there were 40 participants, 20 in each group. Except for psychomotor speed, there was no discernible difference in pre-chemotherapy cognitive test results between patients and healthy controls (HCs). However, there were substantial differences in post-treatment cognition test results, showing that the patient group had progressed. According to longitudinal graph analysis, the patient group’s local and global brain efficiency significantly declined, and lower local efficiency was associated with lower raw Trail Making Test-A results. Furthermore, poorer verbal memory scores were associated with lower overall performance in the sick group but not in the HC group. According to the research, MDA has potential as a supplemental therapy since it may improve brain function and address depression-related neurological abnormalities in cancer patients. More research is required to fully comprehend the variations between cancer and depression-related brain areas during patient therapy, maybe incorporating MDA.

Authors: Aldo Clerico , Martina Zaninotto , Alberto Aimo , Mario Plebani
Published: November 2023

Despite the evidence demonstrating the clinical utility of cardiac specific biomarkers in improving cardiovascular risk evaluation in several clinical conditions, even the most recent reviews and guidelines fail to consider their measurement in order to enhance the accuracy of the evaluation of cardiovascular risk in pregnant women. The aim of this review article was to examine whether the assay of cardiac specific biomarkers can enhance cardiovascular risk evaluation in pregnant women, first by reviewing the relationships between the physiological state of pregnancy and cardiac specific biomarkers. The clinical relevance of brain natriuretic peptide (BNP)/NT-proBNP and high-sensitivity cardiac troponin I/high-sensitivity cardiac troponin T (hs-cTnI/hs-cTnT) assay in improving cardiovascular risk evaluation is examined based on the results of clinical studies on subjects with normal and those with complicated pregnancy. Finally, the analytical approaches and clinical objectives related to cardio specific biomarkers are advocated in order to allow an early and more accurate evaluation of cardiovascular risk in pregnant women.

The growing interest in exploring mushrooms and their bioactive components as potential therapies for diabetes and inflammatory conditions has prompted our investigation. In this study, we examined the methanolic extract, as well as the petroleum ether and ethyl acetate fractions, derived from the fruiting bodies of Hypsizygus ulmarius and assessed the potential in vitro anti-inflammatory and anti-diabetic effects. The inhibition of salivary α-amylase, salivary sucrase, and α-glucosidase enzymes by the methanolic extract and its fractions was used to measure the level of antidiabetic activity. Further, the inhibitory effects of the enzymes lipoxygenase (LOX), cyclooxygenase (COX), and myeloperoxidase (MPO) were tested to assess the anti-inflammatory efficacy of the methanolic extract and its fractions. The fraction containing ethyl acetate has been demonstrated to have the highest level of in vitro antidiabetic effect, exhibiting IC50 values of 44.93, 27.70, and 44.75 μg/ml for salivary α-amylase, salivary sucrase, and α-glucosidase enzymes, respectively. Moreover, the fraction of ethyl acetate revealed the greatest in vitro anti-inflammatory action, with IC50 values of 25.67 μg/ml for LOX, 34.04 μg/ml for COX, and 38.71 μg/ml for MPO.
China’s Central Role in the Globalization and Slowbalization Trends
Authors: Herrero Alicia Garcia
Published: November 2023

China has played a central role in the previous phase of hiper-globalization but also in the ongoing phase of slowbalization, characterized by the decreasing size of global value chains which started after the global financial crisis in 2008. More recently, US-China strategic competition is contributing to the slowbalization process, especially in the technology space. Against such backdrop, China is reducing its dependence on the outside world, betting on technological self-reliance and working hard to build its own ecosystem. However, such trend does not mean isolation; on the contrary, China actively shapes its unique form of globalization by creating its own neighbourhood or area of economic influence. A prominent example of this effort is the Belt and Road Initiative (BRI), which aims at increasing China’s soft – and possibly hard – power with a hub and spoke approach.
Test automation for augmented reality applications: a development process model and case study
Authors: Minor Sascha , Ketoma Vix Kemanji , Meixner Gerrit
Published: November 2023

Poor software quality results in avoidable costs of trillion dollars annually in the United States alone. Augmented Reality (AR) applications are a relatively new software category. Currently there are no standards to guide the development process and testing is predominantly ad hoc and manual. Consequently, design guidelines and software test automation techniques are intended to remedy the situation. Here, we present a concept for test automation of AR applications. The concept consists of two parts: design guidelines and process model for testing AR applications, and a case study with a prototype application for test automation. The design guidelines and the process model are based on the state-of-the-art. The prototype application presented in this article demonstrates test automation for a multi-platform AR application for Android devices as well as the HoloLens 2. The presented test automation case study is designed to cover a large part of the functions, such as the different interaction variants. This research work shows that by using the proposed process model and test automation techniques, testing of some features of AR applications can be automated. The results of this research can serve as a basis for future research and contribution towards AR application development standardization efforts.
Partim donis, partim remissione obsidum captivorumque:
la diplomacia de rehenes y regalos en la Segunda Guerra Púnica en Hispania
Authors: Moreno Eduardo Sánchez , Cardiel Jorge García
Published: November 2023

A lo largo de la Segunda Guerra Púnica, los distintos agentes intervinientes en el frente hispano recurrieron constantemente a la diplomacia, materializada a menudo en el intercambio de regalos. El presente artículo analiza estos intercambios, centrándose en un tipo de dones singularmente valiosos: los seres humanos de estirpe aristocrática previamente reducidos a la condición de rehenes o cautivos. Su eventual liberación, espontánea y unilateral, y las respuestas suscitadas entre sus familiares y comunidades de origen, se comprende mejor desde el punto de vista de las dinámicas de intercambio de dones diplomáticos, generadoras, por definición, de gratitud, ansiedad y reciprocidad entre los interlocutores. En tanto que canal de comunicación, la materialidad diplomática – esto es, la circulación de bienes de prestigio, rehenes, promesas… – sirvió para tejer redes de alianza y para consolidar asimetrías políticas en un escenario bélico progresivamente extensivo y multipolar.
Animal representations in Margaret Atwood’s novels: a study based on pan-indexicality model
Authors: Zhu Jing , Kang Jiying , Duan Chunyun
Published: November 2023

Margaret Atwood is a Canadian author of more than thirty-five books and the winner of prestigious literary prizes, such as the Booker Prize, the Giller Prize, and the Governor General’s Award. Her influence on Canadian literature and contemporary literature as a whole is phenomenal. Nevertheless, little is known with respect to how Atwood represents animals covering the full range of her novels. This paper reports on the analysis of animal representations in Atwood’s seventeen novels through Python programming and close reading under the framework of a new semiotic research finding, a pan-indexicality model within the context of literature and the environment. This study investigates the frequencies of animal vocabulary in the seventeen novels, the changes of animal representations in her novels before 1990s and after 1990s, and the implication of the ever-changing animal representations during the fifty years. This paper concludes that nonhuman animal descriptions in Atwood’s novels of 1970s and 1980s run at a high level and decrease in her novels of 1990s, while scientific animal descriptions increase in her novels of 2000s and 2010s. Nonhuman animals in her novels of 1970s and 1980s are instrumentalized as a vehicle for indigenization and national individuation from the United States, and scientific animals in her novels of 2000s and 2010s are instrumentalized in the service of environmental apocalypticism. This study suggests that the pan-indexicality model can be employed to understand the meaning of signs in literature and the environment from the perspective of authorial intention, with reference to authors’ encyclopedic knowledge, personal experience, social, and cultural background information.
Construction of immunogenic cell death-related molecular subtypes and prognostic signature in colorectal cancer
Authors: Yu Chun , Yang Weixuan , Tian Li , Qin Yue , Gong Yaoyao , Cheng Wenfang
Published: November 2023

Immunotherapy is a promising treatment for advanced colorectal cancers (CRCs). However, immunotherapy resistance remains a common problem. Immunogenic cell death (ICD), a form of regulated cell death, induces adaptive immunity, thereby enhancing anti-tumor immunity. Research increasingly suggests that inducing ICD is a promising avenue for cancer immunotherapy and identifying ICD-related biomarkers for CRCs would create a new direction for targeted therapies. Thus, this study used bioinformatics to address these questions and create a prognostic signature, aiming to improve individualized CRC treatment. We identified two ICD -related molecular subtypes of CRCs. The high subtype showed pronounced immune cell infiltration, high immune activity, and high expression of human leukocyte antigen and immune checkpoints genes. Subsequently, we constructed and validated a prognostic signature comprising six genes (CD1A, TSLP, CD36, TIMP1, MC1R, and NRG1) using random survival forest analyses. Further analysis using this prediction model indicated that patients with CRCs in the low-risk group exhibited favorable clinical outcomes and better immunotherapy responses than those in the high-risk group. Our findings provide novel insights into determining the prognosis and design of personalized immunotherapeutic strategies for patients with CRCs.

Published: November 2023

In this work, a numerical scheme based on shifted Jacobi polynomials (SJPs) is deduced for variable-order fractional differential equations (FDEs). We find numerical solution of consider problem of fractional order. The proposed numerical scheme is based on operational matrices of variable-order differentiation and integration. To create the mentioned operational matrices for variable-order integration and differentiation, SJPs are used. Using the aforementioned operational matrices, we change the problem under consideration into matrix equation. The resultant matrix equation is solved by using Matlab, which executes the Gauss elimination method to provide the necessary numerical solution. The technique is effective and produced reliable outcomes. To determine the effectiveness of the suggested method, the results are compared to the outcomes of some other numerical procedure. Additional examples are included in this article to further clarify the process. For various scale levels and fractional-order values, absolute errors are also recorded.
Heterotopias and the facesphere: “Living Pictures: Photography in Southeast Asia”
Authors: Barbotto Silvia
Published: November 2023

This exploration of the works of various authors and artists will bring us to a philosophical contemplation of the portrait as a heterotopic space. On one hand, a portrait represents the faces of the self and others, embodying both individuality and collectivity. On the other hand, the space within the conventional frame of a portrait transforms from a mere representation of documented reality to a co-constructed and reified form of expression. The article is divided in three parts. The first part sinks into Lotman’s epistemic groundwork on culture, space, and especially art as a founding philosophical and analytical reference and will also outline the relationship and difference between the semiophere and the facesphere. The second part focuses on establishing a relationship between the facesphere and the heterotopic idea of space and portrait genre. Here the article explores Michael Foucault’s thought in relation to heterotopic space, later proposed in association with the space of the portrait. The third part is devoted to establishing relationships between the theoretical background and the analysis of case studies belonging to the portrait genre selected from photographic works in “Living Pictures: Photography in Southeast Asia,” an exhibition at the National Gallery in Singapore. I will conclude with some brief considerations to summarize the path taken.

Published: November 2023

Las malezas son uno de los mayores problemas en la agricultura a nivel mundial, ya que compiten por luz, nutrientes del suelo y otros componentes esenciales para el correcto crecimiento de los cultivos. Las técnicas utilizadas para garantizar el apropiado desarrollo de los cultivos han generado consecuencias negativas para el medio ambiente y la salud, debido al uso excesivo de fertilizantes. Por esta razón, la agricultura moderna ha implementado procesos tecnificados que permiten mejorar la productividad y competitividad del cultivo. La inteligencia artificial ha surgido como una alternativa para solucionar problemas en diferentes sectores industriales, pero su uso en la agricultura es limitado. Por lo tanto, la implementación y desarrollo de una aplicación para dispositivos móviles que permita la detección de malezas en terrenos listos para cultivar representa un gran aporte para el sector agrícola. En la metodología propuesta, se muestra un análisis por color en el espacio CIELAB de un conjunto de imágenes de malezas verdes. Se graficaron todas las tonalidades de la maleza analizada y se clasificaron a través de paralelepípedos rectangulares. Posteriormente, se describe el desarrollo de una aplicación móvil para Android, la cual cuenta con tres funciones: detección de maleza mediante una imagen, video en tiempo real, o selección desde la galería de imágenes. El rendimiento del algoritmo desarrollado se evaluó con tres algoritmos de segmentación Mean Shift, Fuzzy C-Means, K-Means y Otsu, usando la métrica NPR. Los resultados obtenidos indican que el algoritmo desarrollado es el mejor en comparación con los algoritmos de referencia.

La aplicación desarrollada tiene la intención de ser útil para personas involucradas en el área agrícola que buscan detectar automáticamente malezas en sus terrenos, lo que simplifica su trabajo.
¿Qué hay de nuevo en el Método Comparado?: QCA y el análisis de los conjuntos difusos
Authors: Wagemann Claudius
Published: November 2023

En los últimos 25 años, el Análisis Cualitativo Comparativo (QCA, por sus siglas en inglés) ha estado en el centro de atención de la metodología de las ciencias sociales. Se fundamenta en el conjunto de relaciones y objetivos establecidos en el descubrimiento de condiciones suficientes y necesarias -y sus derivadas, como las “INUS” y las “Suin”. Con el QCA es posible modelar la complejidad causal. Este artículo introduce el QCA como una técnica. Posteriormente propone tres aspectos de la complejidad causal que pueden ser manejados con el QCA: la equifinalidad, la relación de causalidad coyuntural y la asimetría. Más adelante se señala que es lo nuevo del QCA y sus alcances, se argumenta que la novedad más importante reside en su capacidad de hacer frente a una comparación sistemática, superar la necesidad de las dicotomías a través del uso de los conjuntos difusos, y tratar los casos como configuraciones. Por último, se enumeran algunos puntos del por qué el QCA debe considerarse como un método “cualitativo” (a pesar de su formalización) y se señalan los retos más importantes que tiene como tal en el futuro.Palabras clave: metodología, comparación, QCA,conjuntos difusos, ciencias sociales.

La capacidad institucional de gobiernos locales en la atención del cambio climático. Un modelo de análisis
Authors: Rosas Huerta Angélica , Gil Montes Verónica
Published: November 2023

En la actualidad el problema del cambio climático es tratado por varios gobiernos locales, pero su actuación se puede ver limitada por su capacidad institucional; es decir, estos gobiernos pueden enfrentar obstáculos o barreras institucionales que les impidan actuar eficazmente. Pero ¿cómo evaluar la capacidad institucional de un gobierno local que trata el problema del cambio climático? El presentetrabajo presenta un modelo conceptual que sirve de referencia para valorar dicha capacidad. Dicho modelo está compuesto por lo que en este trabajo se identifican como los factores institucionales más importantes que determinanla habilidad de las instancias gubernamentales. El modelo se complementa con los atributos que describen dichos factores y las dimensiones que permiten desarrollar las relaciones entre ellos.Palabras clave: cambio climático, capacidad institucional, factores institucionales, modelo de referencia, Gobierno del Distrito Federal
Gobernanza y redes de política pública: un estudio de la vinculación entre gobierno, actores público-sociales y privados en un área local turística
Authors: Vázquez Ceballos Cristo Avimael
Published: November 2023

Desde el marco conceptual de las redes de política pública, este trabajo analiza algunos de los rasgos de los esquemas de gobernanza contemporáneos. Para ello, utilizo el análisis de redes sociales a fin de sistematizar una red de política pública estimulada por un programa público implementado en el pueblo turístico de Valle de Bravo. Los resultados sugieren que se han generado estructuras alternativas para atender los asuntos públicos, en las cuales hay actores no gubernamentales con mayor dominio, así como hay recursos de mayor importancia que los gubernamentales a efecto deque la política funcione.Palabras Clave: dependencia de recursos, propiedades estructurales, actores, red y asuntos públicos.
De violencia y privatizaciones en México: el caso de las Asociaciones Público-Privadas en el sector penitenciario
Authors: Espejel Espinoza Alberto , Díaz Sandoval Mariela
Published: November 2023

El objetivo del presente artículo es explorar e identificar las características de las APP en el sector penitenciario. Sostenemos que se trata de una nueva modalidad de privatizar sectores clave sin representar ventajas para los reclusos. Además, las APP han involucrado un gran dispendio en donde conflictos de interés, corrupción y opacidad van de la mano. Concluimos sosteniendo que la privatización de los aparatos represivos del Estado de ninguna forma contribuirá en disminuir la violencia en el país.Palabras clave: Violencia, privatizaciones, Asociaciones Público-Privadas, sector penitenciario/carcelario, corrupción
Entendiendo el uso y resultados del indicador “Años de vida ajustados por discapacidad”
Authors: González Anaya Teresa
Published: November 2023

Este artículo pretende mostrar el alcance y las limitaciones del indicador “Años de vida ajustados por discapacidad” (AVAD) pero no desde la perspectiva técnica que sustenta la validez y generalidad del indicador, sino desde el punto de vista de la atención y entendimiento de quienes usan este indicador para tomar decisiones. Este artículo se compone de tres secciones: en la primera revisaremos los conceptos teóricos que utilizaremos. En la segunda parte señalamos tres puntos: qué tipo de indicador son los AVAD, cómo sus atraen a audiencias no expertas y qué tan entendibles son los resultados que arroja este indicador para las audiencias no expertas. En las conclusiones, nos enfocamos a recomendar el uso de este indicador a las audiencias no expertas cuando éstas entienden el trasfondo de lo que los AVAD están midiendo.Palabras clave: Indicadores compuestos, años de vida ajustados por discapacidad, años de vida perdidos, años de vida vividos con discapacidad, audiencias no expertas.

Serotonergic neurons in the rostral ventral medulla (RVM) contribute to bidirectional control of pain through modulation of spinal and trigeminal nociceptive networks. Deficits in this pathway are believed to contribute to pathologic pain states, but whether changes in serotonergic mechanisms are pro- or antinociceptive is debated. We used a combination of optogenetics and fiber photometry to examine these mechanisms more closely. We find that optogenetic activation of RVM serotonergic afferents in the spinal cord of naive mice produces mechanical hypersensitivity and conditioned place aversion (CPA). Neuropathic pain, produced by chronic constriction injury of the infraorbital nerve (CCI-ION), evoked a tonic increase in serotonin (5HT) concentrations within the spinal trigeminal nucleus caudalis (SpVc), measured with liquid chromatography-tandem mass spectroscopy (LC-MS/MS). By contract, CCI-ION had no effect on the phasic serotonin transients in SpVc, evoked by noxious pinch, and measured with fiber photometry of a serotonin sensor. These findings suggest that serotonin release in the spinal cord is pronociceptive and that an increase in sustained serotonin signaling, rather than phasic or event driven increases, potentiate nociception in models of chronic pain.

Manganese-doped cadmium sulphide semiconductor nanoparticles (CdS: Mn) NPs have been created utilizing a microwave-assisted solvothermal technique at different Mn concentrations (0, 1%, 3%, and 5%). The chemicals utilized for the preparation of Mndoped CdS nanoparticles were sodium sulphide (Na2S.xH2O), manganese chloride (MnCl2.4H2O), and cadmium acetate (CH3COO)2Cd., H2O). To determine the structural dimensions of the generated nanoparticles, the Debye-Scherer equation was used to calculate the average crystallite size at the full-width half maximum (FWHM) of the diffraction peaks. FTIR spectra analysis was used to look at the various functional and vibrational groups present in the Mn-doped CdS nanoparticle sample. The structure features of the produced nanoparticles have been examined using X-ray diffraction patterns. Energy dispersive X-rays were employed to ascertain the chemical composition of the synthesized nanoparticles. The optical properties and quantification of the energy band gap of the nanoparticles have been done using UV-V spectroscopy. According to XRD calculations, the cubic zinc-blend structure of the generated NPs had a crystal size of between 4 and 7 nm. By using EDX spectroscopy, the incorporation of Mn at the CdS lattice was confirmed.

In this paper, we investigated growth of GaN and Al0.09Ga0.91N epilayer grown on silicon (111) by using II MBE system. The major characterization tools used for this study were high resolution X-ray diffraction (HRXRD), and micro photoluminescence (PL) spectroscopy. Also reported is our attempt to fabricate and characterize metalsemiconductor-metal photodiode based on these films. The responsivity as a function of wavelength for an MSM GaN/Si(111) detector is a sharp cut-off wavelength at 362 nm. A maximum responsivity of 0.256 A/W was achieved at 358 nm. For Al0.09Ga0.91N film, there is a sharp cut-off wavelength at 340 nm. A maximum responsivity of 0.263 A/W was achieved at 338 nm. In UV spectral region, the detector shows a little decrease from 340 to 200 nm. The responsivity of the MSM drops by nearly an order of magnitude across the cut-off wavelength.
