An Efficient Electrocardiography Data Compression
Authors: Luanloet Passakorn , Suwansantisuk Watcharapan , Kumhom Pinit
Published: September 2023

In healthcare, electrocardiography (ECG) sensors generate a large amount of heart electrical signal that must be efficiently compressed to enable fast data transfer and reduce storage costs. Existing methods for ECG data compression do not fully exploit the characteristics of ECG signals, leading to suboptimal compression. This study proposes a data compression technique for ECG data by exploiting the known characteristics of ECG signals. Our approach combines Savitzky-Golay filtering, detrending, discrete cosine transform, scalar quantization, run-length encoding, and Huffman coding for the effective compression. To optimize the compression performance, we generated quantization intervals tailored to the ECG data characteristics. The proposed method experimentally produces a high compression ratio of 127.61 for a design parameter K = 8, a minimum percentage root mean square difference of 1.03% for K = 128, and a maximum quality score (QS) of 39.78, where K is the number of quantization intervals. Moreover, we compared the proposed method to state-of-the-art methods on a widely used ECG benchmark dataset. We found that the proposed method outperforms the others in terms of the QS, which measures the overall compression-decompression ability. By enabling more storage and faster data transfer, the proposed method can facilitate the widespread use and analysis of large volumes of ECG data, thereby contributing to advances in healthcare.

Se presenta en detalle el modelo tradicional de Transferencia de Tecnología, aplicado durante toda su historia en la Federación Nacional de Cafeteros de Colombia. Este ha permitido el cambio técnico, el cual se refleja en variables de alto impacto en la tecnificación de la caficultura del país, tales como densidad de siembra, edad, variedades resistentes, nivel de infestación de broca, nivel de infección de roya, etc. Así mismo, se profundiza en las disciplinas de la comunicación que se deben dominar cuando el extensionista interactúa con los caficultores y los capacita para la adopción de tecnologías, ya sea en forma individual (visitas a fincas) y grupal (reuniones, días de campo. cursos cortos, demostraciones, giras, foros]. Se muestra, además, un Servicio de Extensión con foco de trabajo que busca contribuir a que los caficultores estabilicen o mejoren su productividad y obtengan rentabilidad en la actividad cafetera. Finalmente, se presenta un ejemplo de Charla de Extensión.
Propiedades térmicas y físicas de las nuevas variedades de café
Authors: Duque-Dussán Eduardo
Published: September 2023

La calidad final del café se ve afectada por el proceso de secado, el cual depende de las propiedades termofísicas del grano de café y del aire de secado. Cenicafé ha desarrollado las variedades de café Cenicafé 1 y Castillo® altamente productivas y resistentes a enfermedades, pero aún no se han investigado sus propiedades termofísicas específicas. Este estudio se enfocó en determinar las propiedades termofísicas del café pergamino de estas variedades en cinco diferentes niveles de humedad (53%, 42%, 32%, 22% y 11%), utilizando técnicas y métodos optimizados para garantizar alta precisión y exactitud. Se encontró que estas variedades tienen granos más grandes, pesados y densos, además su conductividad térmica y calor específico a granel son más altos que en otras variedades. A medida que se eliminó la humedad, la densidad aparente, la densidad del grano, la masa, el calor específico del volumen y la conductividad térmica total disminuyeron. Conocer estas propiedades permitirá a los productores y las instalaciones de procesamiento de café mejorar los procesos de secado y tostado para producir un mejor producto final. También pueden actualizarse los modelos matemáticos desarrollados para estimar los tiempos de secado del café y mejorar la precisión de las predicciones.

Authors: Jaramillo Santiago
Published: September 2023

El mayor desafío que enfrentan en el mediano plazo los sistemas de producción de café en Colombia es lograr la sostenibilidad sin que se comprometa su competitividad. Conscientes de la necesidad de aumentar la comprensión, por parte de la comunidad cafetera, de nuevos enfoques productivos que beneficien tanto a los caficultores como al medio ambiente, este seminario abordará las definiciones, principios, prácticas y experiencias de la agricultura regenerativa desde una perspectiva holística y analítica. Adicionalmente, se presentarán los principales avances desarrollados por Cenicafé y transferidos por el Servicio de Extensión como recomendaciones prácticas que pueden ser enmarcadas dentro de este modelo de producción sostenible.
Épocas recomendables para la fertilización del café antes y después de la zoca
Authors: Salazar-Gutiérrez Luis
Published: September 2023

La renovación oportuna y la fertilización del cultivo del café son dos de las prácticas agronómicas que permiten incrementar y mantener la productividad y la rentabilidad. Con respecto a la fertilización, un aspecto importante para mejorar su eficiencia se relaciona con el momento oportuno de la labor, y en cuanto a la renovación, son relevantes los métodos que se emplean, siendo más comunes en Colombia la siembra y la renovación por zoca. Una inquietud frecuente de los caficultores se relaciona con los momentos apropiados para realizar la última fertilización antes de la renovación por zoca y el primer abonamiento después de esta labor. Para responder a las inquietudes planteadas, se realizó una investigación en las Estaciones Experimentales de Cenicafé Naranjal (Chinchiná, Caldas) y Paraguaicito (Buenavista, Quindío), y en la finca La Arcadia (Líbano, Tolima), en café variedad Colombia, de 4 años, desde la siembra en el campo. El cultivo se zoqueó, mediante el corte del tallo a 30 cm del suelo, uno a dos meses después de la última cosecha principal en el quinto año después de la siembra. El zoqueo disminuyó la biomasa de raíces hasta el 65% durante los primeros 12 meses después de la renovación. Para condiciones similares a las del estudio, se recomienda realizar la última fertilización 10 meses antes del zoqueo e iniciar la fertilización entre 6 y 12 meses después del zoqueo, lo anterior teniendo en cuenta la disponibilidad de agua en el suelo, con una alta certeza que ni la producción ni la calidad del grano se afectarán negativamente.
Manejo de la nutrición del café durante la etapa de almácigo
Authors: Sadeghian Siavosh
Published: September 2023

En Colombia se siembran anualmente cerca de 140 millones de colinos de café en aproximadamente 28.000 hectáreas. De la calidad de estos colinos depende el éxito en el establecimiento de las plantaciones y su permanencia en el campo durante los siguientes veinte años; de allí la necesidad de llevar a cabo labores que contribuyan a la obtención de plantas sanas y vigorosas, entre las cuales reviste especial importancia una adecuada nutrición. En este seminario se presentan, a manera de resumen, los resultados de investigaciones desarrolladas por Cenicafé en torno a los requerimientos nutricionales de café durante la etapa de almácigo y la respuesta en crecimiento de las plantas a la aplicación de los diferentes fertilizantes orgánicos y de síntesis química, además de otros insumos como micorrizas y acondicionadores del suelo.

Authors: Góngora Carmenza Esther
Published: September 2023

Con el fin de seleccionar genotipos de Coffea arabica con menor susceptibilidad a la broca del café, se identificaron los materiales silvestres de C. arabica E2 y E5, al igual que materiales híbridos provenientes de estos. Se seleccionaron cuatro híbridos F1: CU1842xE2, CX2385xE2, CX2385xE5 y CX2848xE5. Los materiales fueron propagados in vitro por Embriogénesis Somática Indirecta. Las plantas clonadas fueron trasplantadas a campo en abril de 2018, junto con plantas obtenidas por semilla de dos variedades comerciales. Con los frutos maduros se realizaron dietas artificiales y, usando directamente las semillas, en el laboratorio también se determinó el efecto de estas sobre la broca del café. En las dietas artificiales se observó que los dos híbridos provenientes del E2 causaron las mayores mortalidades en la broca (40%). Evaluando las semillas, se corroboró que estos mismos materiales afectan al insecto con disminuciones del 40% y 50% de las poblaciones de broca con respecto a los demás materiales. Adicionalmente, las plantas en el campo fueron infestadas artificialmente con brocas. Los híbridos CU1842xE2, CX2385xE2 y CX2385xE5 mostraron reducciones de hasta 70% en la población de adultos de broca con respecto a los controles. Las evaluaciones de los híbridos durante 5 años muestran características agronómicas sobresalientes, con una producción de café acumulada superior a los controles, y que para las líneas del E2 duplica la producción, mostrando un mayor número de cruces y vigor híbrido. Se discutirá la pertinencia de realizar propagaciones masivas de estos materiales para evaluar lotes comerciales.
CRITICAL DISCOURSE ANALYSIS (CDA) OF THE 16TH VENICE ARCHITECTURE BIENNALE MANIFESTO
Authors: Topaloğlu Gürkan , Beşgen Asu
Published: September 2023

The Venice Architecture Biennale emerged with post-modern thought in the late 1970s and early 1980s. It is a medium where political, economic and cultural transformations are experienced in the field of architecture and where mainstream global architecture is discussed and shared. Over time, the Venice Architecture Biennale has created a global focal point with the manifestos produced, while bringing together the architectural products and ideas in the ambiguity of the boundaries of local architecture. Biennial manifestos have an ideological structure that is oriented towards social relations in the field of architecture. Looking at the recent Venice Architecture Biennale, it can be said that knowledge production is at the forefront in discourses and products which develops critical thinking. In this context, the study deals with the manifesto1 of the 16th Venice Architecture Biennale. The 2018’s manifesto which was produced within the scope of the biennial; the curator’s ideology is worth examining because of its subjective and objective judgments. For this reason, Norman Fairclough’s critical discourse analysis (CDA) was used in the study to make a critical reading of the biennial manifestos. By using the characteristics of CDA, findings and conclusions were reached in the topics of ideology, interpretation and consistency of the discourse. Due to the nature of the analysis, the findings and conclusions have revealed a new discourse that is controversial in this field.

Published: September 2023

Recent observations have reignited interest in a population of dwarf galaxies that are large and diffuse for their mass, often called ultra-diffuse galaxies (UDGs). However, the origin and evolution of these mass–size outliers and the role of the environment are still unclear. Using the exquisitely deep and wide Hyper Suprime-Cam Strategic Survey images, we search for ultra-puffy galaxies (UPGs), defined as being 1.5σ larger than the average size for their mass, around Milky Way–like galaxies. We present the sizes and radial distributions of mass–size outliers and derive their quenched fraction to explore the impact of the environment. Surprisingly, despite being outliers in size, the UPGs have a similar quenched fraction as normal-sized satellites of Milky Way analogs in both observations and simulations, suggesting that quenching is not tied to being a mass–size outlier. The quenched fraction is higher for the UPGs associated with redder hosts, as well as those that are closer to the host in projection. In contrast, the UDGs are overall redder and more quiescent compared with normal satellites. We show that the classic definition of UDGs is heavily weighted toward quenched galaxies and thus cannot be used for a study of quenching of mass–size outliers.
Entrapment of Hypervolatiles in Interstellar and Cometary H2O and CO2 Ice Analogs
Authors: Simon Alexia , Rajappan Mahesh , Öberg Karin I.
Published: September 2023

Planets and planetesimals acquire their volatiles through ice and gas accretion in protoplanetary disks. In these disks, the division of volatile molecules between the condensed and gaseous phases determines the quantity of volatiles accreted by planets in different regions of the disk. This division can be strongly affected by entrapment of volatiles into less volatile ice matrices, resulting in different radial profiles of common volatiles and elemental ratios than would otherwise be expected. In this study we use laboratory experiments to explore the ability of abundant interstellar and cometary ice matrices, i.e., H2O and CO2, to trap the hypervolatiles 13CO, 12CH4, 15N2, and Ar. We measure entrapment efficiencies through temperature programmed desorption for two ice thicknesses (10 and 50 monolayers) and two mixing ratios (3:1 and 10:1) for each matrix:volatile combination. We find that ice entrapment efficiencies increase with ice thickness and ice mixing ratio to a maximum of ∼65% for all hypervolatiles. Entrapment efficiencies are comparable for all hypervolatiles, and for the two ice matrices. We further find that the entrapment efficiency is relatively insensitive to the ice deposition temperature between 10 and 30 K with the possible exception of CH4 in CO2 ice. Together these results suggest that hypervolatile entrapment at low temperatures (<30 K) is a remarkably robust and species-independent process.

Published: September 2023

By applying our previously developed two-step scheme for galaxy morphology classification, we present a catalog of galaxy morphology for H-band-selected massive galaxies in the COSMOS-DASH field, which includes 17,292 galaxies with stellar mass M
⋆ > 1010
M
⊙ at 0.5 < z < 2.5. The classification scheme is designed to provide a complete morphology classification for galaxies via a combination of two machine-learning steps. We first use an unsupervised machine-learning method (i.e., bagging-based multiclustering) to cluster galaxies into five categories: spherical (SPH), early-type disk, late-type disk, irregular (IRR), and unclassified. About 48% of the galaxies (8258/17,292) are successfully clustered during this step. For the remaining sample, we adopt a supervised machine-learning method (i.e., GoogLeNet) to classify them, during which galaxies that are well classified in the previous step are taken as our training set. Consequently, we obtain a morphology classification result for the full sample. The t-SNE test shows that galaxies in our sample can be well aggregated. We also measure the parametric and nonparametric morphologies of these galaxies. We find that the Sérsic index increases from IRR to SPH and the effective radius decreases from IRR to SPH, consistent with the corresponding definitions. Galaxies from different categories are separately distributed in the G–M
20 space. Such consistencies with other characteristic descriptions of galaxy morphology demonstrate the reliability of our classification result, ensuring that it can be used as a basic catalog for further galaxy studies.
Homogenizing SOHO/EIT and SDO/AIA 171 Å Images: A Deep-learning Approach

Published: September 2023

Extreme-ultraviolet (EUV) images of the Sun are becoming an integral part of space weather prediction tasks. However, having different surveys requires the development of instrument-specific prediction algorithms. As an alternative, it is possible to combine multiple surveys to create a homogeneous data set. In this study, we utilize the temporal overlap of Solar and Heliospheric Observatory Extreme ultraviolet Imaging Telescope and Solar Dynamics Observatory Atmospheric Imaging Assembly 171 Å surveys to train an ensemble of deep-learning models for creating a single homogeneous survey of EUV images for two solar cycles. Prior applications of deep learning have focused on validating the homogeneity of the output while overlooking the systematic estimation of uncertainty. We use an approach called “approximate Bayesian ensembling” to generate an ensemble of models whose uncertainty mimics that of a fully Bayesian neural network at a fraction of the cost. We find that ensemble uncertainty goes down as the training set size increases. Additionally, we show that the model ensemble adds immense value to the prediction by showing higher uncertainty in test data that are not well represented in the training data.
A Dynamically Distinct Stellar Population in the Leading Arm of the Sagittarius Stream
Authors: Kang Gwibong , Lee Young Sun , Kim Young Kwang , Beers Timothy C.
Published: September 2023

We present a chemical and dynamical analysis of the leading arm (LA) and trailing arm (TA) of the Sagittarius (Sgr) stream, as well as for the Sgr dwarf galaxy core (SC), using red giant branch, main-sequence, and RR Lyrae stars from large spectroscopic survey data. The different chemical properties among the LA, TA, and SC generally agree with recent studies and can be understood by a radial metallicity gradient established in the progenitor of the Sgr dwarf, followed by preferential stellar stripping from the outer part of the Sgr progenitor. One striking finding is a relatively larger fraction of low-eccentricity stars (e < 0.4) in the LA than in the TA and SC. The TA and SC exhibit very similar distributions. Considering that a tidal tail stripped off from a dwarf galaxy maintains the orbital properties of its progenitor, we expect that the e-distribution of the LA should be similar to that of the TA and SC. Thus, the disparate behavior of the e-distribution of the LA is of particular interest. Following the analysis of Vasiliev et al., we attempt to explain the different e-distribution by introducing a time-dependent perturbation of the Milky Way by the Large Magellanic Cloud's (LMC) gravitational pull, resulting in substantial evolution of the angular momentum of the LA stars to produce the low-e stars. In addition, we confirm from RR Lyrae stars with high eccentricity (e > 0.6) that the TA stars farther away from the SC are also affected by disturbances from the LMC.

Authors: Mutaru Abdul-Manaf , Nanyim Jonathan Kumah , Adokiya Martin Nyaaba
Published: September 2023

Introduction: Viral hepatitis is one of the major public health concerns, targeted for eradication by 2030. Though previous research has concentrated largely on pregnant women and urban areas, rural populations are reported to be greatly affected in northern Ghana. This study determined knowledge and predictors of attitudes toward hepatitis B virus (HBV) infection prevention among adults in Tolon District, Northern Ghana.
Methodology: This was a population-based cross-sectional descriptive study with a quantitative approach. A multistage stratified random sampling technique was used to select 195 adults. Data were analysed using SPSS version 26. Composite scores were generated for knowledge and attitude levels. At 0.05 precision level, multiple linear regression was performed to determine predictors of respondents’ attitudes.
Results: The overall knowledge level (48.7%) of participants on HBV infection was average, with the majority (67.0%) demonstrating unsatisfactory attitudes towards the prevention. The regression equation was statistically significant (F (3,191) = 61.051), p < 0.001. About half (49%) of the variance in attitude was explained by the independent variables. Participants predicted attitude score was determined as 3.784 – 0.040 (age) + 0.435 (knowledge), where age was measured in years and knowledge was measured as scores on a continuous variable scale.
Conclusions: Knowledge levels are sub-optimal with unsatisfactory attitudes toward HBV infection prevention in the study setting. Participants’ age and knowledge of HBV are significant predictors of attitudes toward its prevention. There is a need to increase access to formal education and health promotion programs in the district, to complement government efforts to attain Sustainable Development Goal 3 (SDG-3).
Molecular evidence and differences in gonopod morphology lead to the recognition of a new species of the freshwater crab genus Candidiopotamon Bott, 1967 (Crustacea, Brachyura, Potamidae) from eastern Taiwan
Authors: Shih Hsi-Te , Naruse Tohru , Schubart Christoph D.
Published: September 2023

A new freshwater crab of the potamid genus Candidiopotamon Bott, 1967, is described from eastern Taiwan. Candidiopotamon penglai sp. nov. is morphologically similar to C. rathbuni (De Man, 1914) from western Taiwan, but can be distinguished by the morphology of the male first gonopod (G1), as well as by their mitochondrial DNA (16S rRNA and COI genes). In the G1 of C. rathbuni, the subterminal segment shows a cline from robust in northern populations to slender in southern populations. In the G1 of C. penglaisp. nov., a distinctly larger and more distally directed keel-like projection is found on the distal inner edge of the terminal segment, with northern populations having an inward-curving subterminal segment and southern populations a straight subterminal segment. The genetic differentiation of the two species of Candidiopotamon within Taiwan is discussed, and morphological differences are compared. A key to the species of Candidiopotamon is also provided.
American Protectionism
Authors: Dadush Uri
Published: September 2023

Les États-Unis, architectes du système commercial de l’après-guerre, sont devenus aujourd’hui son transgresseur le plus visible. L’administration Biden n’a montré aucun intérêt pour de nouveaux accords commerciaux de quelque nature que ce soit. Les États-Unis refusent de renouveler le mandat des juges de l’Organe d’appel de l’OMC, rendant inapplicables les règles de l’OMC, à moins que les États-Unis (ou tout autre membre) ne choisissent de s’y conformer. Dans cet article, sur la base d’une perspective historique, nous examinons les causes du repli (sur soi) de la politique commerciale américaine tout en nous interrogeant sur son évolution future. Aujourd’hui encore, l’économie américaine reste parmi les plus ouvertes au monde, l’opinion publique soutient le commerce et les partisans du retrait des marchés mondiaux sont difficiles à trouver. Il semble donc difficile de voir dans le changement de politique commerciale des États-Unis une adhésion aux valeurs du protectionnisme. Une interprétation plus convaincante réside dans le fait que la politique commerciale américaine évolue, poussée – comme elle l’a été depuis la naissance de la nation – par des forces sous-jacentes, comme la montée de la Chine, l’inégalité des revenus et le changement climatique. Cela nous aide à comprendre la politique de Biden, mais sans pour autant la justifier car la politique actuelle n’est pas la bonne réponse à ces défis. En effet, si l’histoire est un guide, elle nous suggère alors qu’une autre refonte de la politique commerciale américaine est possible et même probable. Malheureusement, un retour au leadership commercial des États-Unis n’est pas envisageable de sitôt, et quand il arrivera, il sera peut-être trop tard pour sauver le système commercial fondé sur des règles.
L’arrogance du simulacre comme solution perverse dans certaines formes de discours radicaux
Authors: Robert Nicolas
Published: September 2023

Cet article interroge le rôle de l’arrogance et du simulacre dans certaines formes de discours radicaux et notamment religieux. Il fait l’hypothèse que le simulacre – comme imaginarisation et érotisation de fonctions humaines normalement à l’œuvre dans la perversion – associé à l’arrogance comme posture, encouragent la constitution de tableaux vivants où la métaphore de l’amour est empêchée et où le langage et ses effets tendent à être entravés.
Arrogance et séduction paranoïaques
Authors: Bercherie Paul
Published: September 2023

Il s’agit d’interroger la capacité paradoxale de la paranoïa dans le champ psychotique à engendrer du lien affectif et social. En retournant d’abord à la définition fondatrice de Kraepelin, centrée sur la production d’un Discours construit et explicatif, de l’ordre du monde et de la place qu’y occupe le sujet. Au-delà de la référence freudienne au pôle narcissique du spectre psychotique, le paranoïaque s’avère ainsi, dans la situation transférentielle en particulier, occuper avec détermination la position du sujet supposé savoir , et se montrer par-là apte à susciter un lien transférentiel de la part de sujets mal structurés en quête de guide dans l’existence, voire de sociétés en crise, en proie au désarroi social et politique.
De la honte à l’arrogance dans la psychose maniaco-dépressive et le travail culturel
Authors: Pascal Jean-Brice
Published: September 2023

La clinique psychiatrique de la psychose maniaco-dépressive est désormais diluée dans lesdits troubles bipolaires. Que ce soit du côté maniaque ou du côté mélancolique, l’arrogance est un symptôme manifeste de ce type de structure psychique. Elle est l’artefact d’un affect oublié par les premiers chercheurs de la psychanalyse : la honte. D’ailleurs, S. Freud avait hypothésé qu’elle faisait défaut au mélancolique. Il sera montré deux idées : l’arrogance est une honte économiquement transformée, participant au tissage qu’entretient la subjectivité au social ; elle est aussi dépendante d’une progrédience du travail culturel au côté de la pulsion de mort.

The Changing Landscape of Global Child Health Education in the United States and the Effects of the COVID-19 Pandemic and Civil Unrest
Authors: Bjorklund Ashley , Muttineni Mounika , Gladding Sophia , Slusher Tina , Howard Cynthia R.
Published: September 2023

The events of recent years have affected the landscape of global child health education (GCHE) in the United States. War, racism, forced displacement, and the coronavirus disease 2019 (COVID-19) pandemic had global repercussions that reached US GCHE. The aim of this article is to examine the effect of these events on the landscape of GCHE in the US. Key areas of GCHE have been reframed, reshaped, and accelerated by these events. Travel restrictions accelerated virtual learning opportunities. Core curriculum needed to be reconsidered to address antiracism, equity, and decolonization. Expansion of GCHE activities, including local-global electives, was needed to meet increased resident demand and help address local community needs. Inequities in international partnerships were further highlighted, requiring new approaches. Global research education and practices were also affected with a rapid expansion in virtual opportunities and further development of education in equitable research practices.

More Than Just a Passport: Resources and Implementation Strategies to Optimize Preparation for Global Health Work
Authors: Winter Jameel J. , Gladding Sophia , Schultz Megan L. , Bensman Rachel , Lam Suet Kam , St Clair Nicole E.
Published: September 2023

During the past decade, many resources have been developed to support trainees and clinicians seeking to prepare for global health work. For time-constrained health care providers, figuring out how to prepare can be overwhelming. Given the wide variation in types of travelers and work plans, there is not a “one size fits all” preparation resource. This article offers a summary of preparation topics that all travelers should consider; compiles curated, high-yield resources designed to prepare health care providers for global health experiences; and provides implementation strategies to best meet the unique needs of each traveler, taking into consideration factors such as provider expertise (trainee vs practicing clinician), solo versus group travel, and time available before departure. These curated resources include a variety of training modalities (self-directed, group-based, train-the-trainer, and in-person courses), all summarized here to empower health care providers to create individualized, comprehensive preparation plans before engaging globally.

Decolonizing Global Child Health Education for More Equitable and Culturally Safe Collaborations
Authors: Tchonang Leuche Viviane , Delgado-Zapata Roberto , Umphrey Lisa , Lam Suet Kam , Cardiel Nunez Kristin , Musiime Victor , Rule Amy
Published: September 2023

Global health (GH) as an academic field is fraught with both historical and present systemic injustice, including unilateral partnerships; power asymmetry in grant funding and research agenda setting; lack of acknowledgment of contributions from low- and middle-income country collaborators; and disadvantageous bias toward low- and middle-income country institutions. Reflecting on the legacies of colonialism and White supremacy is vital for training pediatricians to actively work to improve the health of all children worldwide, within bidirectional and culturally safe partnerships in which power dynamics and ethnocentrism are dismantled. In this article, we discuss the present challenges within academic GH education (GHE) and offer four key action steps to decolonize GHE: (1) reflecting on the history of global child health; (2) creating a new language framework on pertinent concepts in GHE; (3) developing cultural humility, antiracism, and decolonization curricula; and (4) intentional institutional action steps to decolonize and sustain culturally safe global child health education.

Point of Interest recommendation for social network using the Internet of Things and deep reinforcement learning
Authors: Wang Shuguang
Published: September 2023

Point of Interest (POI) recommendation is one of the important means for businesses to fully understand user preferences and meet their personalized needs, laying a solid foundation for the development of e-commerce and social networks. However, traditional social network POI recommendation algorithms suffer from various problems such as low accuracy and low recall. Therefore, a social network POI recommendation algorithm using the Internet of Things (IoT) and deep reinforcement learning (DRL) is proposed. First, the overall framework of the POI recommendation algorithm is designed by integrating IoT technology and DRL algorithm. Second, under the support of this framework, IoT technology is utilized to deeply explore users' personalized preferences for POI recommendation, analyze the internal rules of user check-in behavior and integrate multiple data sources. Finally, a DRL algorithm is used to construct the recommendation model. Multiple data sources are used as input to the model, based on which the check-in probability is calculated to generate the POI recommendation list and complete the design of the social network POI recommendation algorithm. Experimental results show that the accuracy of the proposed algorithm for social network POI recommendation has a maximum value of 98%, the maximum recall is 97% and the root mean square error is low. The recommendation time is short, and the maximum recommendation quality is 0.92, indicating that the recommendation effect of the proposed algorithm is better. By applying this method to the e-commerce field, businesses can fully utilize POI recommendation to recommend products and services that are suitable for users, thus promoting the development of the social economy.
Una lettera dalla Val Varaita a Marsiglia (1883)

Published: September 2023

Une lettre envoyée de l'Alta Val Varaita (commune de Casteldelfino, province de Cuneo) à Marseille, écrite en français par un auteur de langue maternelle occitane dans un contexte politique et administratif italien, est une bonne occasion pour faire quelques observations. Du point de vue historique, la lettre de famille fournit une coupe transversale de la vie intime d'une catégorie sociale, celle des paysans, qui est souvent racontée selon des stéréotypes (aussi en ce qui concerne les compétences d'écriture). Du point de vue linguistique, l'occasion nous permet d'ajouter une petite réflexion sur le rapport avec le français dans une vallée alpine qui a toujours été affectée par les flux migratoires.
L’uso della lingua del Paese d’origine a scuola e in famiglia a Cervia
Authors: Lunardini Francesco , Meluzzi Chiara
Published: September 2023

Dans cette contribution on présente les résultats d’une enquête menée par questionnaire sur les répertoires linguistiques des jeunes d’origine immigrée dans les écoles primaires et secondaires de la commune de Cervia (RA). L’étude devait préciser quelles langues sont utilisées en fonction des différents contextes et interlocuteurs, en particulier dans le domaine scolaire et familial. Les résultats ont démontré la préférence marquée pour les usages multilingues, où certaines langues, pas forcément celle du pays d’origine, côtoient la langue italienne, qui est toujours dominante. La famille est le contexte qui préserve le plus la langue du pays d’origine des immigrés, même si on assiste à un glissement progressif vers l’italien dans l’échange avec les membres les plus jeunes de la famille (la fratrie).
Philologie dans l’atelier du réparateur de vélos

La lingua è la lotta storica del linguaggio con i termini del suo significato, cioè con il significante: una parola, un gesto, uno sguardo. Lotta che consiste nel tentativo di non tradire questo significato nell’espressione del significante. Proprio per questo motivo utilizzo la parola «termine», che presuppone un compimento, un esito. La comunicazione è dunque la nostra preoccupazione primaria, ma non esprime forse già qualcosa di per se stessa, la lingua, prima di qualsivoglia esigenza comunicativa del parlante?
Constitutional theory and the limits to the punitive power: the Italian case of prisoners’ right to judicial protection
Authors: Caputo Giuseppe
Published: September 2023

The growing attention of the Italian Constitutional Court and the European Court of human rights for the judicial protection of prisoners’ rights has placed the prison problem at the centre of the theoretical debate on penalty, after it has always been relegated to an administrative problem. The article, starting from the analysis of the complex hermeneutical operation carried out by the Courts, proposes a theory of the relationship between punitive power and the individual based on a new balance between the opposite paradigms of social defence and the protection of individual rights. Initially this balance was identified by the Courts in the theory of re-education, interpreted reductively as a doctrine of humanization of the punitive power. In more recent years, in response to the re-emergence of neoliberal retributive doctrines, this approach has been integrated with an articulated constitutional theory which invokes the constitutional fundamental rights of the individual as a limit to the punitive power. What emerges is a constitutional theory of punitive power that attempts, partially succeeding, to resolve some theoretical limits of liberal utilitarianism.
Restructuración neoliberal en Colombia: un análisis a partir del pluralismo jurídico transnacional
Authors: Chamorro Rosero Mauricio
Published: September 2023

A fines de la década de 1980, en varios países de América Latina, el neoliberalismo se presentó como la única alternativa para superar la crisis económica provocada por el aumento de la deuda externa. Sin embargo, el despliegue del neoliberalismo supone la implementación de un número importante de reformas estructurales, las cuales fueron presentadas por instituciones económicas y financieras transnacionales. Por ello, tras la revisión de distintas fuentes documentales y bibliográficas, este artículo analiza el proceso de reestructuración neoliberal en Colombia a partir de la influencia de una producción jurídica transnacional. A través del desarrollo de esta investigación se pudo concluir que las políticas económicas provenientes de instituciones económicas y financieras transnacionales han sido incorporadas a los marcos jurídicos estatales de Colombia con el propósito de facilitar la expansión del neoliberalismo. De esta manera, en el contexto neoliberal, la antigua producción jurídica realizada a nivel nacional ha ido incorporando una producción jurídica de carácter transnacional.
Marketing
Authors: Pires Paulo Botelho , Santos José Duarte , Pereira Inês Veiga
Published: September 2023

The article contains a description of the historical evolution of marketing and the evolution of marketing definition. Learning the history of marketing and the evolution of its thinking is supposed to be an inconsequential effort, or at the very least it can be expected to be an unbalanced effort, where the benefits obtained are potentially out of proportion to the commitment required and the knowledge obtained. It is also pertinent to complete the history of marketing with the evolution of the definition of marketing, assessing what has changed over the years to the current version. A table will be presented with a list of the most prominent definitions identified in the bibliography, starting with Converse's 1921 definition and ending with the 2017 AMA definition.
Theory and Practice of Target Financial Forecasting at Company Level
Authors: Krylov Sergey
Published: September 2023

The article considers conceptual, methodical, and practical aspects of the target financial forecasting at the micro level (i.e., the company level) as a new instrument of anticrisis financial management for a company to overcome its financial difficulties and enhance its financial position within a time period of practically any length. The methodology of the research and the results being presented in the article are based on the concept of the financial ratio analysis, the concept of the company cash flows, and the concept of the balanced scorecard (in terms of its financial score). It is depicted that the procedure of the target financial forecasting comprises an appropriate information-accounting support, a target financial forecasting of the company financial position, a target forecasting of the company's cash flows, and a development of the specific events (managements' decisions) aimed at overcoming the company's financial difficulties and enhancing its financial position.

Authors: Sharma Preeti , Kumar Manoj , Sharma Hitesh Kumar
Published: September 2023

A branch of forensic science called “digital forensics” deals with the utilization of digital data received, maintained, and conveyed by electronic devices as evidence in inquiries and legal proceedings. It is a growing field in computing that frequently necessitates the intelligent analysis of large amounts of complex data. Rapid advancements in computer science and information technology enable the development of novel techniques and software for digital investigations. Initially, much of the analysis software was unique and proprietary, but over time, specialised analysis software for both the private and governmental sectors became available. The aim of this chapter is to deliver a comprehensive overview of digital forensics phases, applications, merits, and demerits and widely used software of the domain. The chapter also discusses legitimate and legal considerations, followed by the scope and role of artificial intelligence for solving complex problems of digital forensics.
Technological Trends and Recent Statistics of Dark Web
Authors: Solanki Kamna , Dalal Sandeep
Published: September 2023

The depth of the Internet extends well beyond the surface information that many people may quickly access in their routine searches. Some people may think of the web as only being made up of webpages that can be found using conventional search engines like Google. This information, referred to as the “Surface web,” represents a very small percentage of the entire internet. The part of the internet that search engines and web crawlers do not index is known as the deep web. On the other hand, a subset of the deep web known as the “dark web” is only accessible using specialized software like Tor (The Onion Router). The surface web is primarily used for acceptable daily online activity, while the dark web is purely anonymous and is known for carrying out illicit transactions. The dark web is a small part of the deep web which can be accessed through the Tor browser. This chapter aims to examine current technology developments and some intriguing recent dark web statistics to evaluate the dark web's present state, technologies, usage, and current trends and data breaches.

Project management failure is a broad term that encompasses many different areas of mismanagement, from lack of resources to missed deadlines and budgets. According to a 2018 Project Management Institute (PMI) report, the average global success rate for projects was only 53%, meaning that 47% failed to meet their objectives. This statistic is further supported by a 2020 report from the Standish Group, which found that only 28.3% of projects were successful, meaning that the majority (71.7%) of projects failed to meet their objectives. Project management failure can negatively impact organizations, from decreased productivity to decreased customer satisfaction. Leadership skills are a critical aspect of project success. This chapter explores leadership skill development through executive coaching.

Published: September 2023

Experiential learning is a powerful tool for cultivating autonomous learners and promoting meaningful knowledge and skill transfer to the workplace. This approach to learning became effective when incorporated into organizational training programs, as it boosted learners' willingness to learn and helped to reduce worker turnover. In the wake of the 2021 Great Resignation, in which millions of Americans left their jobs, organizations must embrace evolving forms of instruction and guidance to retain their workers and remain competitive. Organizations spend upwards of $1252 per worker on training. When such organizations miscarry or are unsuccessful in training workers, these workers leave to find different work. This chapter provides an agenda for organizations seeking to implement experiential learning, including peer-group learning, and mentoring. By leveraging these tools, organizations can reap the benefits of experiential learning and ensure that their workers have the skills and knowledge they need to thrive in the ever-changing business landscape.

Published: September 2023

Medical technology powered by artificial intelligence is quickly developing into useful clinical practice solutions. Deep learning algorithms can handle the growing volumes of data produced by mobile monitoring sensors found in wearables, smartphones, and other medical devices. Currently, only a very limited number of clinical practice settings, such as the detection of atrial fibrillation, epilepsy seizures, and hypoglycemia, or the diagnosis of disease based on histopathological examination or medical imaging, benefit from the application of artificial intelligence. Patients have been waiting for the deployment of augmented medicine since it gives them more autonomy and more individualized care, but doctors have been resistant because they weren't ready for such a change in clinical practice. The purpose of this study is to glance over recent scientific material and offer a perspective on the advantages, potential benefits, and potential concerns of established artificial intelligence applications in the modern healthcare sector.
