Authors: Mustafa Anis Adilah , Lym Yong Wilson Thau , Kulip Julius , Francis Rodrigues Kenneth
Published: November 2023

Dendrocalamus asper is a species of bamboo that has high commercial value and is the bamboo of choice for large scale agro-forestry plantations in the tropical regions of the world. Micropropagation using tissue culture is essential to generate uniform clones that are amenable to establishment in industrial agro-forestry projects for bamboo biomass, habitat restoration or in carbon sequestration.  This paper reports on the establishment of D. asper invitro using commercially available seeds. The seeds were surface sterilized using three different chemical agents which were Sodium Hypochlorite (20%), Mercuric Chloride (0.1%) and Ethanol (70%) followed by shoot initiation on Murashige and Skoog (MS) medium supplemented with 6-Benzylaminopurine (BAP) with a concentration ranging from 1.0 - 5.0 mg/L. Propagules were multiplied on MS media supplemented with different concentration of IBA Indole-3-Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA), and finally rooted and hardened in peat moss. The findings of our study indicate that the sterilization protocol eliminated all the plant pathogens, resulting in an axenic culture. Full strength MS medium supplemented with 5 mg/L BAP yielded the highest number of shoots (11.46 per explant) after four weeks of inoculation. The highest multiplication rate (3.95 shoots per explant) was obtained on MS medium supplemented with 3 mg/L BAP. The time required from initiation to hardening was 70 to 90 days, following which the plantlets were ready for field trials. The findings of this study will facilitate the establishment of plant tissue culture programmes dedicated to the production of D. asper locally, thus eliminating the need for imports and the possible entry of plant pathogens that can be detrimental to the local agro-forestry industry.

Published: November 2023

The biggest threats to plant species degradation must be the cutting of trees, conversion into croplands, and natural circumstances. Degradation of land cover has negatively affected plant diversity before the carbon stocks. This study utilized a stratified random sampling technique and allometric equation to determine the plant species, diversity level, and aboveground carbon stocks of trees and understorey found in Matalom, Leyte, Philippines. Results showed thirteen (13) trees and forty-nine (49) understorey species were present in the sampling area. The abundance of species or the total number of individuals per species of trees and understorey is 98 and 2814 respectively. For the diversity index, the result was led by tree species, then understorey species, respectively 1.76, interpreted as very low, and 2.83, which is moderate based on the Modified Fernando Biodiversity Scale. The species evenness, 0.69 and 0.73, was led by understorey plant species. Both signify unequal distribution of plant species in the study area. Moreover, tree species have a higher carbon stock of 34.15 t C haˉ¹ compared to understorey, contributing about 0.03 t C haˉ¹. There are significant differences in the diversity and c-stocks between trees and understorey plant species based on independent t-test results.

Published: November 2023

The present study seeks to investigate the distribution patterns of angiosperm climbers within the Bhadrak district of Odisha, India, along with an assessment of the ecosystem services they provide. The ongoing inquiry into climbing plant species within the Bhadrak district reflects the diversity of 103 species distributed across 71 genera and 33 families. The three most diverse families are Convolvulaceae (22), Cucurbitaceae (15), and Fabaceae (14). Out of 103 climbing plant species, 72 species are herbaceous vines and 31 species are woody vines representing 69.9%, and 30.1%, respectively.  The most common climbing method in the studied sites is stem twining, accounting for 70 species or 68% of the total, the second most common is tendril climbing (22 species, 21.4%), and the least, root climber (2 species, 1.9%). Local communities use these climbers for various purposes. It has been observed that out of 103 species, 61 species have medicinal properties (59.2%), 16 species have ornamental value (15.5%), 17 species are edible (16.5%), and the remaining 8 species have other uses (8.8%). These results indicate the importance of climber communities to plant diversity of Bhadrak district, enhancing the regional diversity and the conservation value of these forest remnants. Habitat degradation because of rapid development activities with limitation of the supporting tree species is found to be a serious threat to climbing plants. Employing a multifaceted strategy such as securing their habitats through protection, restoration, managing invasive species and promoting collaboration among local stakeholders and organizations, ensures the preservation of these vital plants, sustaining biodiversity and ecosystem health for the future.

Published: November 2023

This study documented 11 species of gingers belonging to nine genera distributed in three tribes and two subfamilies from Mt. Musuan and its vicinity in Bukidnon, Southern Philippines. Data revealed that Zingiberaceae species in these sites constitute ca. 8% of the total number of Philippine Zingiberaceae. Alpinia haenkei C.Presl., A. purpurata (Vieill.) K.Schum., Curcuma zedoaria (Christm.) Roscoe, Etlingera philippinensis (Ridl.) R.M.Sm., Hornstedtia conoidea Ridl., Meistera muricarpa (Elmer) Škorničk. & M.F.Newman, and Zingiber zerumbet (L.) Smith. were recorded in Mt. Musuan, while Amomum dealbatum Roxb., Etlingera elatior (Jack) R.M.Sm., Hedychium coronarium Koenig, Hornstedtia conoidea Ridl., and Wurfbainia elegans (Ridl.) Škorničk. & A.D.Poulsen. were collected in CMU View Deck in Kibulawan. Of the collected species, five of these (3.52% endemicity compared to the total number of Philippine Zingiberaceae) are endemic to the Philippines, while the other six species are introduced. These species are mostly associated with fern species, such Dicranopteris linearis (Burm.f.) Underw. and Lygodium circinnatum (Burm.f.) Sw., and angiosperms Musa textilis and under the shades of dipterocarpaceae species. This paper is the first taxonomic report on Zingiberaceae in Mt. Musuan and vicinity which was not   documented in the previous studies conducted at Philippine Long Term Ecological Research (LTER) Sites. Since Mt. Musuan is not a protected area and an open site for ecotourism which is constantly visited by daily hikers, these species might be prone to depletion in their wild habitats. There is an urgent call for in situ conservation efforts that should be done by the concerned authorities of Central Mindanao University to help preserve and protect these ginger species.
Effects of Andrographis paniculata on Carbon Tetrachloride (CCl4)-Mediated Renal Oxidative Damage in Rats

Published: November 2023

A herbal medicinal plant known as Andrographis paniculata, or "hempedu bumi," is recognised for its numerous medicinal properties and role in promoting community health. Despite its widespread use, the potential nephroprotective effects and underlying mechanism of action of Andrographis paniculata remain unexplored. To address this gap, the present study aimed to investigate the nephroprotective effects of Andrographis paniculata against renal oxidative damage induced by carbon tetrachloride (CCl4) in rats. Sprague-Dawley rats were pre-treated with Andrographis paniculata extract via gavage (100, 200, and 300 mg/kg b.w., respectively) once daily for 14 days, followed by two doses of CCl4 (1.2 ml/kg b.w.) on the 13th and 14th days. After two weeks, rats were sacrificed, and a nephroprotective analysis was performed. CCl4 administration at a dose of 1.2 ml/kg body weight resulted in oxidative stress in the renal system, as evidenced by elevated lipid peroxidation levels (TBARS). This oxidative stress was accompanied by a significant decrease in the activities of antioxidant enzymes and a depletion in the levels of reduced glutathione (p<0.05). Histopathological examination confirmed the impairment of renal function. Andrographis paniculata significantly mitigated the majority of these alterations. Based on our research, the nephroprotective advantages of Andrographis paniculata can be attributed to its ability to act as an antioxidant and scavenge free radicals.

Humans have been allegorists since time immemorial. Through this art of narrating, even the most mystical learning has been presented in accessible forms through scripture and doctrine. India too has left a trail of allegories, a metaphorical approach to the basis of creation, including Vastu – the art of spatial planning and geometry. Vastu is often blended with the jargon of mythology, but it is universal when put into practice rationally. This look at it is merely an illustrative introduction to an age-old indigenous architectural practice of Indian origin. The primitives are often mistakenly seen as too naive for today’s world. The following is an attempt to connect the diverging threads of today’s deconstructive intelligence and the enduring metaphysics of Vastu.

Authors: Melo Lúcia de Fátima
Published: November 2023

Trata-se de pesquisa que buscou analisar de que forma os Planos Municipais de Educação e as Leis de Gestão próprias dos 22 municípios que compõem o Estado do Acre, situado na Região Norte brasileira, contemplam a Meta 19 do Plano Nacional de Educação (Lei 13.005/2014) e suas estratégias na consecução da Gestão Democrática da Educação, bem como se as municipalidades cumprem o que ficou estabelecido no artigo 9° desse mesmo plano. As discussões foram balizadas em autores como Azevedo (2014), Ball (2004, 2005, 2011), Dourado (2010, 2017), Mainardes (2006, 2009), Souza (2009, 2018), Scaff e Ferreira (2019), Scaff, Aguiar e Martins (2023), dentre outras referências. A metodologia adotada envolveu revisão bibliográfica e análise documental. As conclusões do estudo evidenciam a inclusão da meta 19 nos Planos Municipais de Educação, bem como a presença de normativas próprias que proclamam a Gestão Democrática nas 22 municipalidades. Contudo, percebe-se uma lacuna de ações políticas eficazes que priorizem a efetivação do processo democrático, existindo um juízo comum sobre a temática, mas com grandes dificuldades para sua consecução, tanto em seus indicadores intraescolares como extraescolares, tal como anunciado nas normativas legais.

Published: November 2023

Objetivamos analisar o sentido de democracia presente no modelo da Tecnologia de Gestão Educacional (TGE), que orienta a gestão das Escolas Cidadãs Integrais (ECI) no estado da Paraíba. Para tanto, utilizamos a abordagem qualitativa e o método documental, tendo como fonte os cadernos da Escola da Escolha, que tratam sobre o modelo de gestão das ECI. Teoricamente, utilizamos os conceitos expressos na Teoria do Discurso de Laclau e Mouffe (2015) e na Democracia Radical de Mouffe (1996; 2003; 2004; 2005; 2015) como principais referências teóricas. Os resultados desta investigação apontaram para a maneira como a TGE vem disputando a hegemonização de um modelo de gestão democrática cunhado nos princípios neoliberais, buscando esvaziar o conflito, a diferença e a pluralidade, ou seja, entendemos que o modelo analisado contribui para o enfraquecimento da democracia pluralista, minando os espaços de construções coletivas, e fortalecendo práticas de responsabilização e da burocratização.

Abstract. The aim of the study was to compare carcass composition and physicochemical and sensory attributes of breast and leg meat from native Mexican guajolote (Meleagris g. gallopavo) as influenced by sex. For this, slaughter weight and carcass characteristics of male (n=8) and female (n=8) guajolotes raised traditionally under extensive systems with similar housing and feeding conditions were recorded. Also, physical characteristics, proximate composition, the fatty acid profile, and sensory attributes were determined in breast and leg meat using standard procedures. The results showed that males had higher (P<0.001) slaughter weight, hot and cold carcass weights, and dressing percentage, as well as carcass part weights, while females had higher (P<0.001) abdominal fat weights than males. The lightness (L*), yellowness (b*), and drip loss values of breast meat, as well as redness (a*) and water-holding capacity values of leg meat, were significantly (P<0.05) influenced by sex. Male breast meat had higher (P<0.05) moisture content, crude protein, erucic acid (C22:1n9), ∑ MUFAs (total monounsaturated fatty acids), ∑ UFAs (unsaturated fatty acids), ∑ DFAs (desirable fatty acids), ∑ UFA / ∑ SFA (total saturated fatty acid) ratio, ∑ PUFA (total polyunsaturated fatty acid) / ∑ SFA ratio, and chewiness scores than females. Likewise, leg meat from males showed higher (P<0.05) ash content, myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1n9c), palmitoleic acid (C16:1n7), ∑ SFAs, ∑ OFAs (odd fatty acids), thrombogenic index, and atherogenic index, whereas females had high fat content. In conclusion, it would be suggested that, from a nutritional point of view, the meat from male guajolotes was preferable to the meat from females.
Martian column CO2 and pressure measurement with differential absorption lidar at 1.96 µm
Authors: Liu Zhaoyan , Lin Bing , Campbell Joel F. , Yu Jirong , Geng Jihong , Jiang Shibin
Published: November 2023

Abstract. By utilizing progress in millijoule-level pulsed fiber lasers operating in the 1.96 µm spectral range, we introduce a concept utilizing a differential absorption barometric lidar designed to operate within the 1.96 µm CO2 absorption band for remote sensing of Martian atmospheric properties. Our focus is on the online wavelength situated in the trough region of two absorption lines, selected due to its insensitivity to laser frequency variations, thus mitigating the necessity for stringent laser frequency stability. Our investigation revolves around a compact lidar configuration, featuring reduced telescope dimensions and lower laser pulse energies. These adjustments are geared towards minimizing costs for potential forthcoming Mars missions. The core measurement objectives encompass the determination of column CO2 absorption optical depth, columnar CO2 abundance, surface air pressure, as well as vertical distributions of dust and cloud layers. Through the amalgamation of surface pressure data with atmospheric temperature insights garnered from sounders and utilizing the barometric formula, the prospect of deducing atmospheric pressure profiles becomes feasible. Simulation studies validate the viability of our approach. Notably, the precision of Martian surface pressure measurements is projected to surpass 1 Pa when the aerial dust optical depth is projected to be under 0.7, a typical air borne dust scenario on Mars, considering a horizontal averaging span of 10 km.
Supervision of seismic velocity models of the Reykjanes Peninsula Rift, SW Iceland
Authors: Ruzek Bohuslav , Doubravova Jana , Horalek Josef
Published: November 2023

Abstract. Most methods for processing seismological data require a suitable velocity model characteristic for the given region being defined. This is also the case of the Reykjanes Peninsula (RP) in SW Iceland, where the REYKJANET seismic network was built to monitor local seismicity in the rift zone. At present, four previously published 1D velocity models (SIL, BRA, TRY and VOG) can potentially be used, prompting us to determine which one is the best. In order to address this issue, we arranged a contest in which all four 1D models and one additional 3D model (T3D) were entered. Uniform methodology for classifying the models was applied and included an analysis of: (i) post-localization travel-time residuals, (ii) residuals of the P-wave first-motion incidence angle and (iii) model-predicted and measured Rayleigh-wave dispersion. We discovered that no single model was unequivocally the most optimal, as the differences between them proved rather minor. A common shortcoming of all the models is the bias of the P-wave first motion incidence angle residuals, which may be a general problem for methods working with P-wave amplitudes (e.g., moment tensor solutions). The VOG model was selected with a weak preference. Finally, we propose a simple method for modifying any of the 1D models by adding a station-dependent surface layer with a vertical velocity gradient. This way, a pseudo-3D model is generated which is fully competitive with a true 3D model while retaining the simplicity of 1D ray tracing. The efficiency of this correction was demonstrated using the VOG model. The corrected VOG model provides post-localization residuals comparable with the true 3D model T3D, has zero bias in predicting the P-wave first-motion incidence angles, and agrees acceptably in predicting the Rayleigh-wave phase-velocity known from other sources. While calculations with a 3D model can be clumsy, the proposed pseudo-3D model is defined by few parameters and is very easy to use. Its applicability is limited to earthquake sources deeper than the deepest lower limit of the topmost layer below the stations.

Abstract. Phytoplankton are responsible for releasing half of the World’s oxygen and for removing large amounts of carbon dioxide from the surface waters. Despite many studies on the topic conducted in the past decades, we are still far from a good understanding of ongoing rapid changes in the Arctic Ocean, and how they will affect phytoplankton and the whole ecosystem. An example is the difference in net primary production modeling estimates, which differ two times globally and fifty times when only the Arctic region is considered. Here we aim to improve the quality of Greenland Sea primary production estimates, by testing different versions of primary production model against in-situ data, and then calculating regional estimates and trends for 1998–2022 for those performing best. As a baseline we chose the commonly used global primary production model and tested it with different combinations of empirical relationships and input data. Local empirical relationships were taken from literature and derived from the unpublished Institute of Oceanology of Polish Academy of Sciences measurements across the Fram Strait. For validation we took historical net primary production 14C data from literature, and added to it our own gross primary production O2 measurements to extend the limited validation dataset. The field data showed expected elevated values at the frontal zone together with differences between Arctic and Atlantic-dominated waters, and unexpected good agreement between primary production measured with 14C and O2 evolution methods. From all the model setups, those including local chlorophyll-a profile and local absorption spectrum and using Level 2 photosynthetically active radiation data, reproduced in-situ data best. Our modeled regional annual primary production estimates equal 346 TgC/year for the Nordic Seas region and 342 TgC/year for the Greenland Sea sector of the Arctic defined as 45° W–15° E, 66°33′N–90° N. These values are higher those previously reported. Monthly values show a seasonal cycle with less monthly variability than previously reported, and with peak values observed in May. No significant increase or decrease in primary production was observed when studying regionally averaged trends. The accuracy of the selected here model setups to reproduce the field data in terms of Root Mean Square Difference is poorer than in the related global studies, but better than in the related Arctic studies.

Abstract. Climate warming and anthropogenic disturbances result in permafrost degradation in cold regions, including in the Qilian Mountains. These changes lead to extensive hillslope thermokarst (HT) formation, such as retrogressive thaw slumps, active-layer detachment slides, and thermal erosion gullies. These in turn cause, e.g., degradation of local vegetation, economic losses, infrastructure damages, and threats to human safety. However, despite its importance, there is currently no thermokarst inventory for the Qilian Mountains. Through manual visual interpretation and field validation, we therefore produce the first quantification of HT features. We count a total of 1064 HT features, with 67 % located in the upper reaches of the Heihe River Basin, which encompasses ~13 % of the Qilian Mountains region. We furthermore document that 82 % of the HT was initiated in the last 10 years. The thermokarst terrain is observed primarily in areas with shallow active layer depth, on northern shaded slopes of 3–25°, with low solar radiation and moderate elevations ranging from 3200 to 4000 m. This first inventory of HT features is an important and missing piece in documenting changes on the Qinghai-Tibetan Plateau, and this new dataset also provides an important basis for further studies on, e.g., quantitative assessment losses caused by HT. The datasets are available from the National Tibetan Plateau/Third Pole Environment Data Center and can be downloaded from https://doi.org/10.11888/Cryos.tpdc.300805 (Peng and Yang, 2023).
The Role of Cybersecurity in Medical Devices Regulation: Future Considerations and Solutions
Authors: Ludvigsen Kaspar Rosager
Published: November 2023

The cybersecurity of medical devices is paramount in a world where everything is increasingly digitised. Attention to how this important defence against malicious actors is regulated must, therefore, also increase. This paper uncovers how the cybersecurity of medical devices is currently regulated and how it can be improved going forward. First, the paper compares the regulation of medical device cybersecurity in the European Union, the United States and the United Kingdom (UK)—differentiating between Great Britain and Northern Ireland as per the current state of the law in the UK. Second, the paper develops a model of how cybersecurity shapes three key areas in the ecosystem of medical devices. These areas are the medical device itself; the structure between the surrounding institutional systems (such as manufacturers and healthcare providers); and the security of the data, the surrounding institutional system and the medical device. Third, based on a comparative analysis and a view of the system from above, the paper puts forward four recommendations on what future regulation should contain to properly regulate the cybersecurity of medical devices: technology specificity, circumvention protection, genuine privacy and security by design. The paper recommends that these four principles be followed. Technology specificity because it guarantees legislation that understands the necessary technical aspects to promote security and safety. Circumvention protection because preventing manufacturers and others from circumventing these requirements decreases risks to the health and wellbeing of patients. Finally, genuine privacy and security by design should be followed to align cybersecurity and privacy with current and future technical capacities.
Zoótropo: vigencia de una máquina para pensar a través del movimiento
Authors: Egea Jorge , Fernández Somoza Gloria , Pereira-Vivas Leonardo , Dalmau Joel
Published: November 2023

Tradicionalmente la máquina estroboscópica, conocida como “zoótropo”, ha sido estudiada como una herramienta primigenia para la creación óptica del movimiento en la imagen animada. Sin embargo, este artículo aborda el zoótropo desde la perspectiva del pensamiento artístico de la imagen en movimiento, por tanto, como “máquina” para la creación artística. En el texto se interrelaciona tres aspectos aparentemente dispares (correspondientes a disciplinas como la historia del arte, la teoría del arte y diseño digital). Estos aspectos son: la búsqueda cinemática de la imagen en términos de arte y la generación del movimiento, origen de la animación, en cuya historia se inserta este instrumento como punto conceptual de partida; el análisis de diversos artistas que trabajan actualmente a partir de los resultados cinéticos del zoótropo para desarrollar un discurso conceptual desde la contemporaneidad, dando un nuevo vigor a este instrumento que sirven como marco fenomenológico para la investigación; y el modelo de diseño digital del zoótropo como fase inicial de investigación teórico-práctica de este equipo, que busca relacionar aspectos entro lo analógico y lo digital como base de la creación artística contemporánea.
An Interview with Peter Stanfield. The Who and the “White Heat” Generation: Politics, Influences and Modernity in the 1960s
Authors: Jordán Soriano Ángeles
Published: November 2023

The 1960s is a decade that has frequently been re-assessed due to the vast number of socio-political changes which occurred in these years—many of them still affecting current society.  In the UK these improvements were promoted under Harold Wilson’s administration (1964-1970), whose political agenda aimed to create an era of modernisation which soon permeated the British arts at all levels. In the particular case of the British band The Who, their songs deliver a particular testimony on issues such as modernity and commodity culture—in some cases, even anticipating a punk attitude, as Peter Stanfield, Emeritus Professor at the University of Kent, notes in one of his most recent books A Band with Built-In Hate: The Who from Pop Art to Punk (2021). The rising interest in this decade, the particularities of this band, and the recent release of material such as the present book have been the reasons to conduct this interview with Peter Stanfield. Moreover, the main aim of this dialogue is to shed light on the views on politics, modernity and society of a band who, due to its particular features—discussed in this interview—has a paramount role to be considered in British Cultural Studies.
La representación de una epidemia de cólera en el haiku de Hasegawa Sosei
Authors: Gutiérrez Cervantes Lenin Emmanuel
Published: November 2023

El presente trabajo es un análisis textual de una secuencia de haiku compuesta por el poeta japonés Hasegawa Sosei (1907-1946) en 1938, cuando se encontraba en China como miembro del Ejército Imperial Japonés durante la segunda guerra sino-japonesa (1937-1945). En la secuencia se describe una epidemia de cólera en un pueblo chino. Tras comentar diferentes teorías sobre la descripción de enfermedades en la literatura y de contextualizar históricamente a Sosei y su obra, se pretende determinar si el haiku es un medio adecuado para representar e informar sobre una enfermedad o sobre un acontecimiento histórico como puede ser la guerra.
Interpretación japonesa del capítulo cuarto del Vimalakīrtinirdeśa-(sūtra). ― La compasión de un auténtico bodhisattva, la cura de la enfermedad y su representación como el nuevo dogma del pensamiento sincretista japonés―
Authors: Villamor Herrero Efraín
Published: November 2023

Entre los primeros escritos exegéticos de textos budistas (Sangyō-gisho 三経義疏) [1] introducidos para el advenimiento de la familia imperial japonesa ―supuestamente bajo la dirección de la incierta figura del príncipe Shōtoku (Taishi) 聖徳 (太子) (574-622 d. C) ― se clasifica el Vimalakīrtinirdeśa-sūtra (VKN)『維摩経』como el texto poseedor de la «sabiduría pragmática» sanadora de cualquier tipo de «padecimiento». La interpretación japonesa de este texto transmitió mucho más que el pensamiento filosófico indio. La glosa de los traductores chinos y sus referencias en sinogramas a la magnificencia de las enseñanzas descritas en este texto cimentaron no el ideal del bodhisattva, sino el nuevo dogma que afianzó las bases del sincretismo japonés, patentado por los más pudientes para su propio beneficio.
El simbolismo del melocotón en la mitología: Su relación con los demonios Oni (鬼)
Authors: Takahashi Minako
Published: November 2023

En las historias en las que aparecen los oni (鬼, demonios) suelen aparecer «melocotones o melocotoneros». Sin embargo, no hay muchos estudios que expliquen su relación. Por ello, este estudio se centra en el vínculo de estos dos elementos, basándose en las teorías de Eliade (1994, 2011) que sugieren que comprender la mitología es comprender el secreto del origen de todas las cosas. Se intentará aclarar lo que simboliza el melocotón y su árbol remitiéndose a la mitología japonesa y china. En ambos países existe la antigua creencia de que el melocotonero y sus frutas ahuyentan a los oni. Espíritus de nuestros antepasados originados de la falta de culto a los muertos que manifiestan su disgusto y resentimiento provocando enfermedades. Por su parte, el melocotonero se presenta como un árbol gigante que crece en la frontera entre el mundo de los muertos y el de los vivos. Su carácter sagrado y su tamaño le permiten funcionar como enlace entre mundos y conectar también con el de las deidades. De su fruto se creía que funcionaba como hechizo de la teoría de los cinco elementos del taoísmo para exorcizar oni y alejar los males que causaban. Esta es la razón por la que los «melocotones» aparecen en historias con oni, y por la que el melocotonero y su fruta simbolizan la salud y la longevidad humanas, repeliendo a los oni.

Dinámicas sociales y acoplamiento estructural: dos elementos clave, pero a menudo olvidados, de la participación comunitaria en los proyectos de Salud Global
Authors: Muela Ribera Joan
Published: November 2023

Este artículo es una reflexión sobre la participación de las comunidades en dos proyectos de Salud Global que usaron Administración Masiva de Medicamentos (AMM). Dada su complejidad, se recomienda la participación comunitaria para adaptar las intervenciones que usan AMM a las condiciones locales. Sin embargo, los estudios que evalúan estas intervenciones se centran más en los problemas de cobertura y en los obstáculos que afectan la adherencia a los fármacos mencionados por los participantes, que en las dinámicas sociales que afectan la participación. En este artículo presento parte de la investigación de dos proyectos en Gambia, con un énfasis en cómo las estructuras, valores y dinámicas sociales afectaron la adherencia. Finalmente concluyo que es más relevante acoplar el proyecto a estas estructuras y dinámicas, que enfocarse en “reparar” los problemas con información y educación para la salud.
