Authors: Miranda Medina María
Published: January 2024

RESUMEN: Este artículo se centra en el Neptuno alegórico de sor Juana Inés de la Cruz y su carácter de tríptico reflejado en tres personajes mitológicos: Neptuno, Isis y Minerva. Buscaré explorar los lazos genealógicos que la autora traza entre ellos, haciendo de Isis la madre de Neptuno y de Minerva su hija y doble, analizando también las relaciones con la dimensionalidad de su obra: Isis corresponde al arco triunfal (dimensión estructural), Neptuno se asocia al texto (dimensión literaria) y Minerva se encuentra ligada a la celebración (dimensión performática). Además, indagaré en la simbología detrás de cada personaje: Isis al representar la creación, Neptuno al encarnar el conocimiento y Minerva, los actos de conocimiento.

Abstract: My work focuses on the Neptuno alegórico by Sor Juana Inés de la Cruz and its tripartite character reflected through three mythological characters: Neptune, Isis, and Minerva. I seek to explore the genealogical connections that the author draws between them, positioning Isis as Neptune's mother and Minerva as his daughter and double. At the same time, I will also analyze their relationships to the dimensionality of the author's work, where Isis corresponds to the triumphal arch (structural dimension), Neptune is associated with the text (literary dimension), and Minerva is related to the celebration (performative dimension). I will also expand on the symbology behind each character: Isis representing creation, Neptune embodying knowledge, and Minerva being the acts of knowledge. My aim is to show how, by planning the construction of the triumphal arch for the new viceroy, the author creates a philosophical framework that validates her own practice of writing and learning.
On-chip octave-spanning flat supercontinuum in all-normal-dispersion silicon nitride waveguides

Published: January 2024

On-chip supercontinuum generators have emerged as an attractive optical source with small size, broad spectrum and high power efficiency. Nevertheless, there has long been a trade-off between spectral uniformity and bandwidth. We propose a novel silicon nitride waveguide with flat saddle-shaped all-normal dispersion, particularly for enhancing the nonlinear interactions over a wide band. By launching a 250-fs 30-kW input pulse, an ultra-flat (-6 dB) octave-spanning supercontinuum extending from 638 nm to 1477 nm can be generated. We analyze the performance of the supercontinuum generator in terms of spectral flatness and bandwidth under different input pulse conditions. Thanks to mature dispersion engineering, the pump wavelength can be flexibly selected within the flat dispersion region. The generated supercontinuum, therefore, can be applied to different spectral regions by shifting the center wavelength.

Published: January 2024

Mid-infrared (MIR) dual-comb spectroscopy (DCS) is a highly effective method for molecular metrology of rovibrational transition spectra in a quick accurate manner. However, due to limited comb frequency instability, manipulating coherence between two frequency combs to accomplish high-quality spectral analysis in the MIR region is a huge challenge. Here, we developed a comb-teeth resolved MIR DCS based on active phase control cooperating with a CWs-dependent (CWD) interferogram timing correction. Firstly, four meticulously engineered actuators were individually integrated into two near-infrared (NIR) seed combs to facilitate active coherence maintenance. Subsequently, two PPLN waveguides were adopted to achieve parallel difference frequency generations (DFG), directly achieving a coherent MIR dual-comb spectrometer. To improve coherence and signal-to-noise ratio (SNR), a CWD resampled interferogram timing correction was used to optimize the merit of DCS from 7.5 × 105 to 2.5 × 106. Meanwhile, we carried out the measurement of MIR DCS on the methane hot-band absorption spectra (v3 band), which exhibited a good agreement with HITRAN by a standard deviation on recording residual of 0.76%. These experimental results confirm that this MIR DCS with CWD interferogram timing correction has significant potential to characterize the rovibrational transitions of MIR molecules.

Published: January 2024

To the best of our knowledge, a novel extensible multi-wavelength (EMW) method to interrogate arbitrary cavities in low-fineness fiber-optic multi-cavity Fabry-Pérot interferometric (LFMFPI) sensors is proposed and experimentally demonstrated. Based on the derived model of the LFMFPI sensor with any amount of cascaded cavities, theoretically, variation in each cavity of a LFMFPI sensor can be extracted simultaneously once the necessary parameters are acquired in advance. The feasibility of this method is successfully demonstrated in simulations and experiments utilizing LFMFPI sensors. In experiments with the LFMFPI sensor, optical path differences (OPD) of 78 nm and 2.95 µm introduced by temperature variation in two cavities, and the OPD induced by vibration with the amplitude from 5.891 nm to 38.116 nm were extracted, respectively. The EMW method is potential in multi-parameter sensing for pressure, vibration, and temperature.
Inferring country-specific import risk of diseases from the world air transportation network

Published: January 2024

Disease propagation between countries strongly depends on their effective distance, a measure derived from the world air transportation network (WAN). It reduces the complex spreading patterns of a pandemic to a wave-like propagation from the outbreak country, establishing a linear relationship to the arrival time of the unmitigated spread of a disease. However, in the early stages of an outbreak, what concerns decision-makers in countries is understanding the relative risk of active cases arriving in their country—essentially, the likelihood that an active case boarding an airplane at the outbreak location will reach them. While there are data-fitted models available to estimate these risks, accurate mechanistic, parameter-free models are still lacking. Therefore, we introduce the ‘import risk’ model in this study, which defines import probabilities using the effective-distance framework. The model assumes that airline passengers are distributed along the shortest path tree that starts at the outbreak’s origin. In combination with a random walk, we account for all possible paths, thus inferring predominant connecting flights. Our model outperforms other mobility models, such as the radiation and gravity model with varying distance types, and it improves further if additional geographic information is included. The import risk model’s precision increases for countries with stronger connections within the WAN, and it reveals a geographic distance dependence that implies a pull- rather than a push-dynamic in the distribution process.
Mycobacterium tuberculosis response to cholesterol is integrated with environmental pH and potassium levels via a lipid metabolism regulator
Authors: Chen Yue , MacGilvary Nathan J. , Tan Shumin
Published: January 2024

Successful colonization of the host requires Mycobacterium tuberculosis (Mtb) to sense and respond coordinately to disparate environmental cues during infection and adapt its physiology. However, how Mtb response to environmental cues and the availability of key carbon sources may be integrated is poorly understood. Here, by exploiting a reporter-based genetic screen, we have unexpectedly found that overexpression of transcription factors involved in Mtb lipid metabolism altered the dampening effect of low environmental potassium concentrations ([K+]) on the pH response of Mtb. Cholesterol is a major carbon source for Mtb during infection, and transcriptional analyses revealed that Mtb response to acidic pH was augmented in the presence of cholesterol and vice versa. Strikingly, deletion of the putative lipid regulator mce3R had little effect on Mtb transcriptional response to acidic pH or cholesterol individually, but resulted specifically in loss of cholesterol response augmentation in the simultaneous presence of acidic pH. Similarly, while mce3R deletion had little effect on Mtb response to low environmental [K+] alone, augmentation of the low [K+] response by the simultaneous presence of cholesterol was lost in the mutant. Finally, a mce3R deletion mutant was attenuated for growth in foamy macrophages and for colonization in a murine infection model that recapitulates caseous necrotic lesions and the presence of foamy macrophages. These findings reveal the critical coordination between Mtb response to environmental cues and cholesterol, a vital carbon source, and establishes Mce3R as a transcription factor that crucially serves to integrate these signals.

Published: January 2024

Current models of early human subsistence economies suggest a focus on large mammal hunting. To evaluate this hypothesis, we examine human bone stable isotope chemistry of 24 individuals from the early Holocene sites of Wilamaya Patjxa (9.0–8.7 cal. ka) and Soro Mik’aya Patjxa (8.0–6.5 cal. ka) located at 3800 meters above sea level on the Andean Altiplano, Peru. Contrary to expectation, Bayesian mixing models based on the isotope chemistry reveal that plants dominated the diet, comprising 70–95% of the average diet. Paleoethnobotanical data further show that tubers may have been the most prominent subsistence resource. These findings update our understanding of earliest forager economies and the pathway to agricultural economies in the Andean highlands. The findings furthermore suggest that the initial subsistence economies of early human populations adapting to new landscapes may have been more plant oriented than current models suggest.
Food insecurity and water management shocks in Saudi Arabia: Bayesian VAR analysis
Authors: Elzaki Raga M. , Al-Mahish Mohammed
Published: January 2024

The existing conditions of domestic agricultural production and the resulting products will not be able to fruitfully address the increasing food demand due to the limited fertile land and water resources in Saudi Arabia. Moreover, the escalating threat of a hotter climate, the deterioration in precipitation, and harsh droughts in Saudi Arabia have reduced the predictability of water management efficiency and resulted in the exhaustion of water bodies and serious degradation of ecosystems that have directly affected agricultural systems and indirectly, food security. This study also aims to assess the impact of water efficiency on food insecurity in Saudi Arabia. The study applied the Bayesian Vector Autoregressive (BVAR) model for the reference period for the data extended from 2000–2020. Likewise, we used both impulse response functions (IRFs) and forecasting variance error decomposition (FVED) through 1000 Monte Carlo simulations according to the BVAR model to examine both the response of food insecurity to the shocks on water management efficiency used for various purposes and the decomposition of error variance in food insecurity. The results show that food insecurity was not observed throughout this study. The results of the BVAR analysis indicate that in the short run, the coefficients of water use efficiency are significant based on the Food Insecurity Multidimensional Index (FIMI). Also, the BVAR model provides a better forecast with an interdependence on water use efficiency for agricultural purposes and FIMI. Moreover, the results obtained from IRFs have shown a significant effect of water efficiency on FIMI. Water use efficiency for agriculture and industrial purposes reduces food insecurity while increasing water for services use increases food insecurity. Water use efficiency is the key factor affecting food insecurity in the short run. The results reveal that the water use efficiency shocks will decrease food insecurity. The shocks experienced by food insecurity can be predicted as self-shock over a span of ten years. Emphasis is given to the task of water management that may support food security in Saudi Arabia through implementing and enhancing the water use efficiency as an integral part of achieving the SDGs in Saudi Arabia.
Modelling microplastic bioaccumulation and biomagnification potential in the Galápagos penguin ecosystem using Ecopath and Ecosim (EwE) with Ecotracer

Published: January 2024

Bioaccumulation and biomagnification of anthropogenic particles are crucial factors in assessing microplastic impacts to marine ecosystems. Microplastic pollution poses a significant threat to iconic and often endangered species but examining their tissues and gut contents for contaminant analysis via lethal sampling is challenging due to ethical concerns and animal care restrictions. Incorporating empirical data from prey items and fecal matter into models can help trace microplastic movement through food webs. In this study, the Galápagos penguin food web served as an indicator species to assess microplastic bioaccumulation and biomagnification potential using trophodynamic Ecopath with Ecosim (EwE) modelling with Ecotracer. Empirical data collected from surface seawater near Galápagos penguin colonies, zooplankton, penguin prey, and penguin scat in October 2021 were used to inform the ecosystem model. Multiple scenarios, including a 99% elimination rate, were employed to assess model sensitivity. Model predictions revealed that microplastics can bioaccumulate in all predator-prey relationships, but biomagnification is highly dependent on the elimination rate. It establishes the need for more research into elimination rates of different plastics, which is a critical missing gap in current microplastic ecotoxicological and bioaccumulation science. Compared to empirical data, modelling efforts underpredicted microplastic concentrations in zooplankton and over-predicted concentrations in fish. Ultimately, the ecosystem modelling provides novel insights into potential microplastics’ bioaccumulation and biomagnification risks. These findings can support regional marine plastic pollution management efforts to conserve native and endemic species of the Galápagos Islands and the Galápagos Marine Reserve.
The Kominsky Method, Michael Douglas and Alan Arkin: Fashionable impairments of an ageing Hollywood
Authors: Pesce Sara
Published: January 2024

The series The Kominsky Method (Netflix, 2018–20) stars Michael Douglas and Alan Arkin as two ageing members of today’s Hollywood milieu. Sandy Kominsky (Douglas) is an acting coach. His effort of self-preservation and perpetuation of the star’s charisma clashes with corporeal decay and financial collapse. Norman Newlander (Arkin) is Sandy’s agent and caustic friend. He has peculiar death thoughts and constantly makes humorous reference to both men’s physical, psychological and social disparities. What does Kominsky tell us about contemporary celebrity culture as regards ageing and the crisis of public appearance thereto related? The show reveals film and television industry’s leading position in setting desirable or disputable models of old age through a renovated alliance with fashion. Arkin and Douglas’s looks express the shame of old age but also glamorize it. A self-reflexive narrative testifies Hollywood’s search for innovative strategies of self-representation that includes old age, showcasing the transformation of celebrated bodies and underlying the value of personal flexibility. Amid the decline of their image and influence, Douglas and Arkin develop a new adaptability, demonstrated variously in terms of masculine aesthetics, through clothing, living spaces, gestures and dialogue. This article investigates the implied social meaning attached to the dressed old body in the public sphere when the predicaments concern privilege and influence. The main character’s costumes draw on fashion trends such as dandyism, hipster style and vintage. Arkin’s, on the other hand, stick to the classic, although not in a strict formal way. Their juxtaposition reveals how fashion trends come to the aid of celebrities’ effort to overcome crisis, a means to manage as well as spectacularize confused and ambivalent attitudes to ageing.
The sociality of driverless cars in Life on Wheels
Authors: Naghavi Nasim , Cucuzzella Carmela
Published: January 2024

The ubiquity of automobiles has made it so that a considerable amount of space is devoted to them in cities. In the past, urban scholars considered these car-dedicated spaces to be ‘non-places’ that hindered place attachment and social life in cities. This article investigates new place-making efforts in these spaces by examining the documentary film Life on Wheels that offers alternatives. Within the ‘new mobility paradigm’, social space is considered an assemblage of social interactions, objects (e.g. technologies), geographical locations, emplacements and communication networks. Through the analysis of the film, this article investigates the social opportunities and challenges that driverless cars may bring to the urban space. More specifically, in this article, the film shows that the technoscape of driverless cars can direct the city towards a shift in socio-spatial urban design and planning. A profound analytical reading illuminates the need for further social development of this technology. While the technoscape of driverless cars in the current state is in its infancy, its produced social space is yet to be scrutinized; However, at this stage of technology development, the film shows that the driverless environment can help us work towards a new way of understanding mobility spaces and their socio-technological characteristics. This article identifies the social urbanism in car-dedicated spaces projected in films and how this social urbanism can be attainable via new technologies or a transformational shift in mobility.
The city in film: Reading Dhobi Ghat and Island City as cinematic representations of Mumbai
Authors: Machado Glynis , Jana Ujjwal
Published: January 2024

Urban spaces harbour the capacity to embody varied social relations that constantly interact to form lived experiences. As the society has gradually transformed from a collection of rural settlements to a largely metropolitan space, urban fiction as a literary genre set in city landscapes has become increasingly popular. In a century dominated by new media technologies, the changing contours of contemporary societies became widely visible in the images and interpretations available through cinema. Cinema as one of the predominant modes of cultural expressions has played a performative role in encapsulating the changing lifestyles, attitudes and landscapes. The city as a mosaic of complexity, diversity and contradictions has consequently become an inseparable part of the world’s largest film industry – Bollywood. The Indian megacity of Mumbai has thus become a site of ‘glocal’ interconnections and polyphonic voices. Not only has the city contributed to the production and dissemination of films, but its increased influence has also allowed it to feature as a ‘character’ in many films. This article seeks to evaluate select cinematic narratives to foreground the living realities of the megacity of Mumbai. While examining the representation of Mumbai in two films released post-2010 – Dhobi Ghat (Mumbai Diaries) and Island City, the article intends to interpret the implicit and explicit meanings in the cinematic language of these films. It seeks to argue that cinematic representations of Mumbai help to characterize ways of perceiving the city as a complex, multi-layered urban text. Rather than visualizing the city as an empty space that simply holds the narrative together, the article aims to show how cities in films become characters themselves, engulfing those of flesh and bone.

Oregano (Origanum vulgare L.) is widely used as a spicy-aromatic, essential-oil and medicinal culture in various sectors of the economy. The steam distillation method was used to obtain samples of essential oil of plants of new varieties of oregano, cultivated in the conditions of the Republic of Belarus. More than 20 components were identified in the essential oils of oregano, the main of them are the sabinene, limonene, β-ocimene, germacrene D. Essential oils of oregano of varieties ‘Zavirukha’ and ‘Aksamit’ have antibacterial activity in relation to gram-negative and gram-positive bacteria. The more pronounced antimicrobial properties of essential oils from oregano plants with white (‘Zavirukha’ variety) in comparison with pink (‘Aksamit’variety) aureoles of flower are due to the increased content of tymol and eugenol. The obtained results on the content, component and enantiomeric composition of essential oils, as well as their antibacterial properties, allow us to more fully assess the quality of oregano with the prospect of its use in various sectors of the economy.

Published: January 2024

The structure of silver modified powder cellulose isolated from hardwood lignocellulose was investigated using X-ray structural analysis and computer modeling. Full-profile analysis proved that the studied sample corresponds to the monoclinic phase of cellulose Iβ with an antiparallel arrangement of molecules. The unit cell parameters were a = 7.881 Å, b = 7.837 Å, c = 10.603 Å, and γ = 95.63°; the volume V = 652 Å3. The sizes of coherent scattering regions (CSR) of the sample calculated with a Scherrer method were determined to analyze the supramolecular structure. An increase of CSR was observed in the [100] direction and a decrease was found in the [001] direction compared to CSR of the powder lignocellulose. Cross-section area of the fibril of the modified sample in plane ab (980 Å2) was found to be ~8% larger than that of powder cellulose. The crystallinity index (CI) calculated with a Ruland method was found to be 79% which was 7% higher than that of powder cellulose. The final cluster of the silver containing powder cellulose had a chemical formula of C6O5H10.12Ag0.08.

In this work the new, one-step methods for the synthesis of allobetulin 3-O-lactate from betulin and birch bark were proposed. The composition of the obtained samples of allobetulin 3-O-lactate after recrystallization from ethanol and acetone was determined by elemental analysis, and its structure was confirmed by IR and NMR spectroscopy for the first time. The melting point of allobetulin 3-O-lactate is 225–226 °C. The one-step method for the preparation of allobetulin 3-O-lactate from betulin is based on the combination of the stages of isomerization of betulin in the presence of sulfuric acid and the formation of ester with lactic acid, that does not require an additional stage of allobetulin synthesis. The yield of allobetulin 3-O-lactate is 77 wt%. The one-stage method of obtaining allobetulin 3-O-lactate directly from birch bark is based on combining the stages of betulin extraction, its isomerization into allobetulin and esterification of allobetulin, it allowed to exclude the stages of betulin extraction and allobetulin synthesis. The yield of allobetulin 3-O-lactate is 12% of the mass of absolutely dry birch bark (~32%wt. of betulin contained in it). Taking into account that allobetulin and its derivatives have antibacterial, immunotropic, anti-ulcer and antiviral activity, and lactic acid derivatives show immunomodulatory, anti-inflammatory and antimicrobial activity, it can be expected that allobetulin 3-O-lactate will show improved pharmacological properties compared to the starting substances.
Ordonans o handlu lądowym z 1673 roku (Kodeks Savary'ego)
Authors: Klimaszewska Anna
Published: January 2024

The Ordinance of Commerce was the first codification of commercial law which contained many provisions that regulated the accepted commercial practices. Consequently, it became very successful both in France and beyond its borders. It also created the French doctrine of commercial law. However, objective factors as well as a narrow approach of the main legislator – creator of the Act – led to a situation in which the ordinance, although useful for the practitioners, or traders, presented many imperfections on the theoretical side. Members of the Committee were too prudent and avoided general, or abstract concepts, in consequence of which the Code Savary was incapable of fully protecting "traders acting in good faith against ignobility." Moreover, since the Act allowed a longer litigation process and thus created higher costs, at the same time diminishing the efficiency of the Court work. Last but not least, the Ordinance of Commerce met with little social understanding and many difficulties in its application.

Published: January 2024

Nature-inspired metaheuristic optimization algorithms have many applications and are more often studied than conventional optimization techniques. This article uses the mountain gazelle optimizer, a recently created algorithm, and artificial neural network to optimize mechanical components in relation to vehicle component optimization. The family formation, territory-building, and food-finding strategies of mountain gazelles serve as the major inspirations for the algorithm. In order to optimize various engineering challenges, the base algorithm (MGO) is hybridized with the Nelder–Mead algorithm (HMGO-NM) in the current work. This considered algorithm was applied to solve four different categories, namely automobile, manufacturing, construction, and mechanical engineering optimization tasks. Moreover, the obtained results are compared in terms of statistics with well-known algorithms. The results and findings show the dominance of the studied algorithm over the rest of the optimizers. This being said the HMGO algorithm can be applied to a common range of applications in various industrial and real-world problems.

Chalcone is an important biosynthetic precursor, due to the diverse pharmacological activities. The aim of this current study was to synthesize 14 new chalcone derivatives compounds by incorporating p-alkoxyacetophenones with substituted benzaldehydes. Two new series of chalcone derivatives have been synthesized using the alkylation and the base catalysed Claisen-Schmidt condensation. All the synthesized compounds were fully characterized by IR, 1D NMR (1H and 13C NMR) and 2D NMR (COSY, HMQC, HMBC) as well as mass spectrometry analysis. All the synthesized compounds were assayed in vitro for their antituberculosis activities against Mycobacterium tuberculosis strain. Among them, compounds (E)-1-[4-(heptoxy)phenyl]-3-(2-hydroxy-5-bromophenyl)prop-2-en-1-one (5a), (E)-1-[4-(octyloxy)phenyl]-3-(2-hydroxy-5-bromophenyl)prop-2-en-1-one (5b) and (E)-1-[4-(decyloxy)phenyl]-3-(2-hydroxy-5-bromophenyl)prop-2-en-1-one (5d) showed good activities with the lowest MIC value of 12.5 μg/mL.

Published: January 2024

In order to determine the optimal wall pressure location as the controlled parameter for kerosene-fueled scramjet, a combined approach of numerical simulation and experimental analysis was employed. The results indicate that with an increase in the equivalence ratio of kerosene, the combustor exhibits consecutive modes, including pure scramjet mode, dual-mode scramjet mode, dual-mode ramjet mode, and pressure disturbance to the isolator inlet mode. The peak pressure ratios corresponding to the mode transition boundaries are 1.95, 3.26, and 3.57, with respective isolator outlet Mach numbers of 1.62, 1.0, and 0.74. The equivalence ratio corresponding to mode transition increases with an increase in the combustor inlet total temperature. Considering the dynamic characteristics of wall pressures at different locations, the position at x/L = 0.46 demonstrates the best linearity, highest sensitivity, and greater stability. Hence, it is the most suitable choice as the controlled parameter for fuel flow in this kerosene-fueled scramjet.

This paper explores social responsibility training as part of university educational programmes. The authors compare French and Bulgarian students’ perceptions of various elements of social responsibility and how social responsibility is approached in universities’ curricula. Bulgarian students see social responsibility more often in terms of volunteer work, charitable activities and career opportunities, while French students associate it with environmental aspects. The only statistically significant gender difference in Bulgaria emerged in linking improving working conditions with social responsibility. French students placed stronger emphasis on business and the possible practical applications of social responsibility training offered by universities.

The TIME project: Timing and Sound in Musical Microrhythm (2017–2022) studied microrhythm; that is, how dynamic envelope, timbre, and center frequency, as well as the microtiming of a variety of sounds, affect their perceived rhythmic properties. The project involved theoretical work regarding the basic aspects of microrhythm; experimental studies of microrhythm perception, exploring both stimulus features and the participants’ enculturated expertise; observational studies of how musicians produce particular microrhythms; and ethnographic studies of musicians’ descriptions of microrhythm. Collectively, we show that: (a) altering the microstructure of a sound (“what” the sound is) changes its perceived temporal location (“when” it occurs), (b) there are systematic effects of core acoustic factors (duration, attack) on microrhythmic perception, (c) microrhythmic features in longer and more complex sounds can give rise to different perceptions of the same sound, and (d) musicians are highly aware of microrhythms and have developed vocabularies for describing them. In addition, our results shed light on conflicting results regarding the effect of microtiming on the “grooviness” of a rhythm. Our use of multiple, interdisciplinary methodologies enabled us to uncover the complexity of microrhythm perception and production in both laboratory and real-world musical contexts.
Energy transitions research: An assessment methodology
Authors: Segura Karen Gabriela Liñán
Published: January 2024

Market rules, changes in regulations for users and producers, technological innovation and economic development are important factors shaping energy transitions. Therefore, explaining energy transitions requires a multidisciplinary insight to investigate these factors. The study of energy transitions faces an analytical and methodological challenge, particularly in communicating trends shaping the energy systems in developing economies. The existing literature is not consistent in identifying these disciplines nor proposing how they can be combined. In this sense, this paper proposes a new and simple methodological path to assess variables and theories. It conceptualizes energy transitions as a co-evolution of two types of systems: system innovation with its roots in evolutionary, institutional economics, science and technology studies (STS); and energy systems with its roots in neoclassical and evolutionary economics. From how to conduct a systematic literature review, to how best integrate theories and the analytical framework in which key questions can be answered, the paper elevates the role of political science, as policies play a prominent role in shaping energy transitions. This paper responds to those who have pointed out that the political economy of energy transitions is a vastly understudied area.

En este trabajo propongo un recorrido por la obra de Roberto Bolaño, centrado en el concepto de heterocronía, un aspecto a menudo pasado por alto en su escritura, que presenta tiempos otros en constante fricción. Esa pugna desnuda una incomodidad frente a un presente neoliberal que ha vuelto a los personajes obsoletos, buscando olvidarlos y dejar atrás su pasado militante. Sin embargo, esa misma incomodidad subraya las tensiones y contradicciones entre diferentes momentos históricos. En un contexto social y político de amnesia, y que pretende instalar una narrativa monocrónica, Bolaño se rebela contra la homogeneidad histórica forzada introduciendo en ella un tiempo otro que permite su reapertura y cuestionamiento.

O artigo apresenta os resultados de survey sobre trajetórias profissionais de jornalistas brasileiros de 2012 a 2017, período em que às transformações estruturais do ofício se somou a complexa crise política, econômica e social no Brasil. Iniciado com manifestações de massa em 2013, o período de tensões políticas no país foi transmitido e fomentado por grandes empresas jornalísticas. O survey foi respondido em 2017 por 1.233 profissionais que, cinco anos antes, haviam participado de pesquisa de perfil da categoria. Os dados permitem a comparação direta de informações sobre a posição ocupacional dos respondentes nos dois momentos, além de recolherem representações dos jornalistas a respeito dos efeitos das duas crises sobre seu trabalho.
Vídeos em 360º : narrativas em jornalismo imersivo e exercício da cidadania no combate à desinformação

Published: January 2024

A evolução tecnológica vem impactando a prática jornalística, possibilitando estratégias de aproximação entre os receptores e a realidade retratada. A ilusão de presença de um receptor no cenário narrativo onde se passa o fato, em vídeos de 360º, que abordam temas sociais, significaria um maior nível de participação que levaria a um exercício da cidadania mais consciente? O objetivo central deste artigo é analisar as narrativas jornalísticas apresentadas em vídeos de 360º, sobre refugiados de guerras, publicados no canal The Daily 360º The New York Times, no YouTube e, em particular, do vídeo The Displaced. O método utilizado é a análise crítica da narrativa proposto por Motta (2007), que se propõe a analisar as narrativas como processos sociais

Authors:   Universidad Nacional de Avellaneda (UNDAV), PROFETA Damián , GÓMEZ Celeste ,   Universidad Nacional de Avellaneda (UNDAV)
Published: January 2024

Este artículo explora estrategias visuales en el periodismo de datos y presenta hallazgos de investigación a partir de entrevistas con referentes de América Latina. El periodismo de datos, una rama del periodismo de investigación, emplea tecnologías digitales e internet para recopilar, procesar y analizar grandes volúmenes de datos para producir noticias. Una característica distintiva de esta práctica es la inclusión de representaciones visuales, que no solo atraen estéticamente, sino también pueden facilitar el acceso, comprensión e interpretación de la información. Este estudio pretende contribuir al desarrollo del ámbito profesional y académico del periodismo de datos y sus dimensiones visuales, explorando cómo estas estrategias pueden aplicarse de manera más efectiva para comunicar información compleja a audiencias amplias.
Neurociencia, Identidad, y aprendizaje

El bajo rendimiento escolar ya se había analizado previamente a la pandemia, y algunas investigaciones apuntaban a diagnósticos socio emocionales La neurosiquiatra infanto-juvenil Amanda Céspedes en su trabajo clínico ha constatado el stress, la depresión y las crisis en niños y jóvenes escolares desnutridos socioemocionalmente. Con la investigación cerebral de la neurociencia, a fines del siglo XX, se ha introducido una fuerte atención al subdesarrollo de las capacidades emocionales de niños y jóvenes como carencias desmotivadoras de su aprendizaje escolar.

Vicente Alanís, un pintor sevillano en la Baja Extremadura. Revisión a su catálogo de obras.
Authors: Cabezas García Álvaro
Published: January 2024

Vicente Alanís was the Sevillian painter who most openly derived from late baroque aesthetics into the most typical academicism advocated by the Royal School of the Three Noble Arts, a board in which he held several positions and in which his professional career ended. In 1795 he executed the painting Animas in the parish of Santa María de la Encina and San Juan Bautista, in the town of Burguillos del Cerro, Badajoz. The canvas testifies the aroma of historical thought in a place other than a heart of power at the end of the Old Regime, and shows the importance of the of art ideas and influence trafficking. As a result of this discovery, I have been able to add some other works to his oeuvre.
Entre el barroco y el clasicismo: Manuel García de Santiago, una nueva obra documentada para su repertorio
Authors: Guijo Pérez Salvador , Macías Giráldez Raúl Antonio
Published: January 2024

This study attempts to delve into the figure of Manuel García de Santiago, a mem-ber of the García de Santiago saga. This family of artists settled in Seville with the figure of Bartolomé García de Santiago in the mid-17th century and maintained their artistic work until the early 19th century. To this end, the aim is to carry out a biblio-graphical survey on this figure, analysing a new work of art documented after its resto-ration in 2016. This is the image of Our Lady of the Rosary, the Marian patron saint of the Sacramental Brotherhood of the parish of San Bartolomé de Mairena del Alcor, in the province of Seville.
La contribución arquitectónica de Ventura Vaca en Alburquerque a lo largo del tiempo: nuevas aportaciones y significaciones
Authors: Bargón García Marina
Published: January 2024

Recently, an architectural project by the architect Ventura Vaca was discovered in the context of the town of Alburquerque, Badajoz. This discovery has significantly expanded our understanding of Ventura Vaca's relevance and influence in a specific geographical region, while enriching our interpretation of his own architectural work.

Furthermore, this research undertakes an incipient analysis of the history of the Casas Consistoriales de Alburquerque, with a focus on the project proposed by Ventura Vaca for this building. This project is considered to be the starting point that gave rise to the final town hall construction, which was carried out by the architect Donato Hernández Ruiz.

Therefore, this study contributes significantly to the existing knowledge about Ventura Vaca, highlighting his crucial role as the driving force behind the transformation of the town of Alburquerque from a rural to an urban society.

This study proposes a primary screening system for diagnosing sarcopenia in older adults through anthropometric measures. This exploratory research initially involved 150 elderly individuals, of whom 122 were selected after a data purification process. Using machine learning techniques such as hierarchical clustering and decision trees, the original set of 13 anthropometric measures was reduced to five key features. Three classification systems were created: the first based on previously established parameters (appendicular muscle mass, walking speed, and grip strength); the second considered upper limb measures (average muscle mass of both arms, grip strength, walking speed, and body fat percentage); and the third focused on lower limb measures (average muscle mass of both legs, grip strength, walking speed, and body fat percentage). These classification systems were clinically validated in a group of 57 patients previously diagnosed by specialists, of which 10 received a positive sarcopenia diagnosis. The results showed similar efficiencies in all three systems, with eight of the ten known positive diagnoses classified in the same group. Additionally, the study provides specific cut-off points for each system, thus facilitating the clinical diagnosis of sarcopenia by medical professionals.

Polmacoxib is a novel nonsteroidal anti-inflammatory drug (NSAID) that has shown significant interest in recent years for its potential therapeutic benefits in Osteoarthritis treatment and distinct analytical characteristics. The chemical and pharmacological section in this review depicts the choice of solvents to be used through its solubility profile and the mechanism of action which focuses on inhibition of both cyclooxygenase-2 (COX-2) and carbon anhydrase inhibition with subsequent modulation of prostaglandin synthesis. The clinical trial of polmacoxib shows especially the phase 3 trial explains majorly about the safety and efficacy of the drug and explains why it is the chosen one among other NSAIDs. Data from randomized controlled trials and observational studies provides understanding of its use in patient population, expressing its potential as an alternate NSAID. Analytical methods for polmacoxib, such as Reverse Phase High Performance Liquid Chromatography (RP-HPLC), Differential Scanning Calorimetry (DSC), and Powder X-Ray Diffraction (PXRD) are highlighted in this review. The RP-HPLC is developed for quantification of drug, while DSC and PXRD reveals about the solid-state property of CG100649 which will be useful in formulation and stability studies. In conclusion, this review article provides critical information regarding the drug Polmacoxib with its chemical and pharmacological properties, trials conducted as well as analytical procedures performed.
