La idea de “crisis ambiental” en la praxis: sentido débil y sentido fuerte
Authors: Prieto Martín
Published: December 2024

En este trabajo se aborda la categoría de crisis ambiental global como clave interpretativa para orientar disputas sistémicas. El objetivo principal de este trabajo es proponer una demarcación general entre dos sentidos de crisis ambiental, uno más débil o amplio y otro más fuerte o restringido, que caracterice la diferencia en el patrón y nivel de realización en que las rupturas metabólicas actuales se traducen en términos de tendencias sistémicas contrapuestas. Para trazar esta distinción, se describe primero un suelo común de nociones asociadas a la crisis ambiental. Segundo, se analizan las condiciones (epistemológicas y políticas) de posibilidad conceptual y oportunidad práctica para elaborarla a partir de dichas nociones.
La flexión hacia la interioridad de un pensamiento reabierto a la relacionalidad. Estructura y dinamismo ontológico-existencial del "cogito" pascaliano
Authors: Peratoner Alberto
Published: December 2024

La invitación agustiniana al redi in teipsum parece recurrir en la variante moderna de la investigación de la interioridad que se puede observar en dos autores como Descartes y Pascal, aunque con trayectorias diferentes. El cogito pascaliano, si bien se estructura de forma similar al cartesiano, se expresa en el redescubrimiento del pensamiento como razón de la dignidad del hombre y núcleo identificador de la constitución antropológica, que conduce a la determinación del sentido de la estructura de la conciencia como constitutivamente relacional. El interiorismo de inspiración agustiniana que reencontramos en Pascal, en su misma estructura ontológico-consciencial y existencial-dinámica a la vez, tiene una valencia simultáneamente filosófica y teológico-espiritual, y la misma producción pascaliana está atravesada e impregnada por la necesidad de un retorno incesante a la interioridad de la conciencia, perseguida como condición necesaria para la cualificación ontológico-existencial de la persona como ser esencialmente en relación.

This study investigates the factors influencing Ghanaian students' choice of technical and vocational education (TVET) career pathway. The study was guided by the social cognitive career theory and the expectation-value theory. The cross-sectional descriptive survey design was used to explore the critical factors influencing students’ technical and vocational education choices. Specifically, the study explored the demographic profile of TVET students, determined the factors the factors that influenced their enrolment into TVET programmes, and their level of satisfaction with the choices they are pursuing. The targeted population were students enrolled in TVET programmes in two Technical Institutes in the Cape Coast Metropolis. Using the census method, a structured questionnaire was used to collect data from 245 participants.  Data collected were analysed and interpreted using descriptive statistics.  The study revealed that parental influence, particularly from fathers, is the primary motivating factor. Other motivators included interest in practical skills, opportunity for self-employment, and job prospects. Respondents also reported that the negative perceptions about TVET, associating it with lower academic ability and prestige always affect their motivation. However, students expressed satisfaction with their decision and choice of programmes citing the practical aspects, teaching methods, availability of tools and equipment and overall school environment as factors driving their interest and satisfaction. Notwithstanding, some respondents saw the cost of programme and support for placement as factors that negate their decision    The study concludes that, engaging parents and school agents, promoting public awareness, enhancing TVET’s image and aligning curricula with industry while offering assistance with internship, placement and financial support could improve enrollment rates. It is therefore recommended that parents be engaged in career guidance programmes and teachers trained to offer balanced career advice to students. Additionally, efforts must be made to align TVET programme curricula with industry needs and improve school infrastructure to enhance the appeal of TVET programmes, while financial support is provided for students to help increase programme accessibility.

Considerando a influência dos aspectos afetivos, seja no ambiente familiar ou escolar, no desenvolvimento da criança e na sua formação escolar, pessoal e social, visando o seu melhor desempenho, o presente estudo teve como principal objetivo compreender como as relações afetivas podem contribuir para reduzir as dificuldades de aprendizagem que estão ligadas à problemática familiar. A metodologia utilizada foi um estudo de natureza básica, de caráter descritivo e abordagem qualitativa, tendo como procedimento um estudo de campo na Escola Municipal Maria José Nóbrega de Figueiredo Moura, localizada no município de São José do Belmonte, Pernambuco. Os sujeitos da pesquisa foram os 05 professores do Ensino Fundamental II, tendo como instrumento de coleta de dados a aplicação de um questionário. Os resultados apontaram que quanto maior e efetivos forem os vínculos no ambiente da sala de aula, e da escola com a família, os resultados de aprendizagem serão melhores se houver a interação de todos os envolvidos neste processo, até porque, a aproximação permitirá o conhecimento sobre as verdadeiras necessidades e potencialidades de cada um, o que facilitará o desenvolvimento de propostas facilitadoras e eficazes na produção de conhecimentos. Foi apontado pelos professores que os estudantes apresentam dificuldade de interação, e que a escola busca realizar ações que possam reduzir a carência dos mesmos. Concluindo que a escola, o professor e demais integrantes da equipe pedagógica, precisam compreender que além de um ser aprendente, há no estudante um indivíduo com sentimentos, desejos, medos, frustrações, sonhos, etc., que precisa ser considerado em sua totalidade. A escola não pode ser compreendida simplesmente como um espaço de aglomeração de meros receptores de informações e conhecimentos, nela deve existir também o comprometimento com a pessoa, com isso, a afetividade deve tornar-se um aspecto sempre presente no contexto da sala de aula e no ambiente escolar.

Racism in Brazil is structural. To combat it, it is necessary that the Government propose affirmative actions to promote economic and social equality for the insertion of the black population in society. These affirmative actions are forms of public policies that aim to promote well-being and citizenship to ensure equal opportunities and treatment among people and the mobilization of cultural sectors with the intention of expanding social inclusion actions. The Dignity of the Human Person is a fundamental right inscribed in the Brazilian Federal Constitution, inserted in article 1, item III. The objective of this paper was to discuss the principle of the dignity of the human person as a legal good protected by the Federal Constitution in the crimes of racism in Brazil. To this end, historical and social aspects will be addressed, as well as the effectiveness of these affirmative public policies that aim to promote the insertion of the black population in society.

As Infecções Relacionadas à Assistência à Saúde (IRAS) são reconhecidas mundialmente como um grave problema de saúde pública, pois aumentam a morbidade, a mortalidade, bem como os custos gerais do sistema hospitalar. São adquiridas após um paciente ser admitido em um serviço de saúde, podendo manifestar-se durante a internação ou após a alta. Para ser considerada IRAS, a infecção deve estar relacionada a um procedimento de assistência à saúde ou a uma internação. As infecções mais frequentemente encontradas nos hospitais estão relacionadas a uso de dispositivos invasivos, tempo de internação, procedimentos cirúrgicos, usos de imunossupressores e infecções por microrganismos multirresistentes. Diante do contexto apresentado o objetivo dessa pesquisa é descrever as estratégias e ações realizadas pelo enfermeiro quanto à prevenção e o controle de infecções relacionadas à assistência em Centros de Terapia Intensiva (CTI), analisando a influência do profissional de enfermagem no controle desses eventos adversos.
Retrieval of top-of-atmosphere fluxes from combined EarthCARE lidar, imager, and broadband radiometer observations: the BMA-FLX product

Published: December 2024

Abstract. The Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) satellite mission is expected to provide new insights into aerosols, clouds, and radiation. The satellite's payload includes four instruments designed to synergistically retrieve vertical profiles of clouds and aerosols, along with the atmospheric radiation data. This will enable the determination of atmospheric heating rates and top-of-atmosphere radiances and fluxes. This paper focuses on the BMA-FLX processor, specifically created, developed, and validated to retrieve thermal and solar top-of-atmosphere radiative fluxes from longwave and shortwave radiances, measured along track by the EarthCARE Broad-Band Radiometer (BBR) instrument. These radiances are co-registered either at the surface or, in cloudy conditions, at the radiatively most significant vertical layer of the atmosphere (reference level). The Multi-Spectral Imager (MSI) and Atmospheric Lidar (ATLID) on board EarthCARE support cloud identification, while meteorological data from the European Centre for Medium-Range Weather Forecasts provide the surface and atmospheric necessary information. In the BMA-FLX processor, flux is estimated independently for each BBR view using different approaches for the longwave and shortwave radiances. A combined flux, derived from co-registered radiances at the reference level, is provided as the best estimate for a given scene. The radiance-to-flux conversion algorithms have been successfully validated through end-to-end verification using L1 and L2 synthetic data for three EarthCARE orbits. In general, a good agreement is found between the retrieved fluxes and the model truth, with root mean square errors (RMSEs) varying between 7 and 18 W m−2 for the solar fluxes and lower than 6 W m−2 for the thermal fluxes. The BMA-FLX's objective is to achieve radiative closure for EarthCARE with solar and thermal fluxes within 10 W m−2.
Controls of aeolian and fluvial sediment influx to the northern Red Sea over the last 220 000 years

Published: December 2024

Abstract. Present-day sediment influx to the northern Red Sea is dominated by aeolian dust because of its position between the large deserts of northern Africa, the Arabian Peninsula and the Levant, and the absence of discharge from perennial rivers. However, sediment cores retrieved from the northern Red Sea reveal strong temporal variability of dust influx to the basin on glacial-interglacial timescales and several shorter-term strong episodes of fluvial input. We report new palaeoclimate and sediment provenance records for the last ca. 220 kyr from marine sediment core KL23, retrieved from the northern part of this basin. Our data suggest that the Nile delta became a major dust source during glacial conditions, in response to the glacioeustatic sea-level fall and associated subaerial exposure of volcanic-rich debris originally transported down the river Nile from the Ethiopian Highlands. Windblown dust from this delta source is characterized by high smectite concentrations and Ti contents. It is transported to the northern Red Sea on prevailing NNW winds. Our data also suggest a contribution of kaolinite-rich windblown dust from Egypt, Sinai and the Levant to KL23 with the same winds. The activity of this source is hydrologically controlled, with minima in kaolinite concentrations documenting phases of increased humidity, probably due to enhanced Mediterranean cyclogenesis and a southward expansion of the Mediterranean winter rains. Short-term reactivations of wadi systems during fluvial episodes are identified by fine grain sizes, high chlorite concentrations and high εNd. These episodes correlate with phases of reduced aeolian influx to the northern Red Sea and coincide with African Humid Periods, both in timing and relative intensity. This result implies that the Mediterranean climate system and the African monsoon are closely coupled.
On the impact of thunder on cloud ice crystals and droplets
Authors: Kourtidis Konstantinos , Stathopoulos Stavros , Amiridis Vassilis
Published: December 2024

Abstract. Calculations are presented on the impact of thunder on cloud particles. The results show that the creation of a shockwave front near the lightning channel results in shattering of ice crystals, droplets, and dust aerosols, the former being a yet unidentified mechanism for secondary ice production in clouds. At low altitudes shattering is more efficient. At the distance where the shockwave front decays to audio wave, it can cause agglomeration of particles. The cloud particles’ characteristics appear not very suitable for extensive acoustic agglomeration if the Sound Pressure Level (SPL) is below 120 dB. Nevertheless, even for SPL<120 dB, some agglomeration will occur. Agglomeration will occur readily if SPL>135 dB at sound frequencies 10–200 Hz. Agglomeration efficiency increases with height. More agglomeration will occur in pyroclouds, due to their large particle number densities. These results show that the electrical environment in clouds has, through thunder, effects on the size distribution and number density of ice particles and droplets, will hence influence thundercloud radiative properties, and it may be a significant driver of secondary ice production. As global warming may influence the occurrence rate of lightning, the mechanisms discussed here may induce a climate feedback.

Published: December 2024

Abstract. The Arctic Ocean is undergoing rapid transformation due to climate change, with decreasing sea ice contributing to a predicted increase in primary productivity. A critical factor determining future productivity in this region is the availability of nitrogen, a key nutrient that often limits biological growth in Arctic waters. The fixation of dinitrogen (N2) gas, a biological process mediated by diazotrophs, not only supplies new nitrogen to the ecosystem but also plays a central role in shaping the biological productivity of the Arctic. Historically it was believed to be limited to oligotrophic tropical and subtropical oceans, Arctic N2 fixation has only garnered significant attention over the past decade, leaving a gap in our understanding of its magnitude, the diazotrophic community, and potential environmental drivers. In this study, we investigated N2 fixation rates and the diazotrophic community in Arctic coastal waters, using a combination of isotope labeling, genetic analyses and biogeochemical profiling, in order to explore its response to glacial meltwater, nutrient availability and its impact on primary productivity. Here we show, N2 fixation rates, ranging from 0.16 to 2.71 nmol N L-1 d-1, to be notably higher than those observed in many other oceanic regions, suggesting a previously unrecognized significance of N2 fixation in these high-latitude waters. The diazotrophic community is predominantly composed of UCYN-A. We found highest N2 fixation rates co-occurring with maximum chlorophyll a concentrations and primary production rates at a station in the Vaigat Strait close impacted by glacier meltwater inflow, possibly providing otherwise limiting nutrients. Our findings illustrate the importance of N2 fixation in an environment previously not considered important for this process and provide insights into its response to the projected melting of the polar ice cover.
Secondary Organic Aerosol Formation from Nitrate Radical Oxidation of Styrene: Aerosol Yields, Chemical Composition, and Hydrolysis of Organic Nitrates
Authors: Wang Yuchen , Zhang Xiang , Huang Yuanlong , Liang Yutong , Ng Nga L.
Published: December 2024

Abstract. Styrene is emitted from anthropogenic sources and biomass burning and is highly reactive towards atmospheric oxidants. While it has the highest nitrate radical (NO3) reactivity among aromatic hydrocarbons, the NO3 oxidation of styrene and formation mechanisms of secondary organic aerosols (SOA) have not been investigated. In this study, we conduct chamber experiments with styrene concentrations ranging from 9.5–155.2 ppb. The resulting SOA yields range from 14.0–22.1 % with the aerosol mass loadings of 5.9–147.6 µg/m³ after wall loss corrections. The chemical composition of SOA is characterized by online measurements, revealing that dimeric organic nitrates (ONs) constitute 90.9 % of the total signal of particle-phase products. C16H16N2O8 and C8H9NO4 are identified as the major particle-phase products, which constitute 88.3 % and 4.1 % of the measured signal, respectively. We propose formation mechanisms for the ON products, including the common RO2+RO2/HO2 pathway and other radical chain termination reactions such as RO+R and R+R. We also investigate the hydrolysis of particulate ONs. The hydrolysis lifetime for ONs is determined to be less than 30 minutes. This short hydrolysis lifetime can be attributed to the stabilization of the carbocation by delocalized π orbitals of the benzene-related skeleton of aromatic ONs. This work provides the first fundamental laboratory data to evaluate SOA production from styrene+NO3 chemistry. Additionally, the formation mechanisms of aromatic ONs are reported for the first time, highlighting that compounds previously identified as nitroaromatics in ambient field campaigns could also be attributed to aromatic ONs.
Post-fire evolution of ravel transport regimes in the Diablo Range, CA

Published: December 2024

Abstract. Post-fire changes to the transport regime of dry ravel, which describes the gravity-driven transport of individual particles downslope, are poorly constrained but critical to understand as ravel may contribute to elevated sediment fluxes and associated debris flow activity observed post-fire in the western United States. In this study, we evaluated post-fire variability in dry ravel travel distance exceedance probabilities and disentrainment rates in the Diablo Range of central coastal California following the Santa Clara Unit Lightning Complex fire of August 2020. Between March 2021 and March 2022, we conducted repeat field experiments simulating ravel with in situ particles (3–35 mm diameter) on a range of experimental surface gradients (0.38–0.81) on both grassy south-facing slopes and oak woodland north-facing slopes. We characterized post-fire evolution in particle transport by fitting a probabilistic Lomax distribution model to the empirical travel distance exceedance probabilities for each experimental particle size, surface gradient, and time period. The resulting Lomax shape and scale parameters were used to identify the transport regime for each subset of simulated ravel, ranging from “bounded” (light-tailed or local) to “runaway” (heavy-tailed or nonlocal) motion. Our experimental results indicated that as vegetation recovered over the first 2 years post-fire, the behavior of small particles (median intermediate axis of 6 mm) became less similar across the experimental sites due to different vegetation structures, whereas medium and large particles (median intermediate axes of 13 and 28 mm, respectively) exhibited a general transition from more runaway to more bounded transport, and large particles became less sensitive to surface gradient. All particle sizes exhibited a decrease in the length scale of transport with time. Of all particle subsets, larger particles on steeper slopes were more likely to experience nonlocal transport, consistent with previous observations and theory. These findings are further corroborated by hillslope and channel deposits, which suggest that large particles were preferentially evacuated from the hillslope to the channel during or immediately after the fire. Our results indicate that nonlocal transport of in situ particles likely occurs in the experimental study catchment, and the presence of wildfire increases the likelihood of nonlocal transport, particularly on steeper slopes.
Optimizing Incidence Angle and Range for Single-Shot Laser Scanning Point Clouds to Model Aerospace Fasteners
Authors: Pexman Kate , Robson Stuart
Published: December 2024

Abstract. In high-precision manufacturing environments, optical metrology technologies allow on-line checking and validation, offering live digital representations, with the broader potential to create digital manufacturing twins. An established typical aerospace application involves the alignment of assemblies where components need to be compared against design tolerances at key manufacturing stages. Accurate, precise and reliable measurement tools such as laser trackers are the popular choice for such processes in large-volume manufacturing settings. A critical aerospace challenge follows alignment, drilling and fastening operations enabling surface covers to be attached to underpinning structures, where the smallest manufacturing variations can cause excess drag impacting aerodynamic performance. Determining surface conformance of airstream facing surfaces challenges laser tracker systems which, whilst capable of localised surface scanning, require costly large volume robotics to productively measure large wing surfaces at high levels of local detail. This technology gap creates opportunity for the use of 3D imaging devices such as medium range laser scanners and detection strategies such as automated feature detection from point clouds. In this work, various laser scanner devices were used to detect fasteners of different sizes on a fastener sample plate from a single shot setup. This fastener sample plate is representative of a typical aerospace surface and is comprised of common aerospace materials. Highly precise measurements, in the range of 0.5 mm were achieved, and conclusions were drawn about optimal range and incidence angle for both aerodynamic and interior sides of an aerospace surface.
360° Borescope with Adjustable LED Lighting: A Solution for Photogrammetry in Extremely Restricted Spaces
Authors: Barazzetti Luigi , Previtali Mattia , Roncoroni Fabio , Valente Riccardo
Published: December 2024

Abstract. The system described in the paper is a prototype of a novel 360° borescope for digital documentation in confined spaces. The method was designed for both 360° inspections and photogrammetric applications in very tight and narrow spaces (even less than 30–40 cm), in which traditional digital documentation is usually impossible. The prototype is based on a panoramic camera and an integrated lighting LED system to allow for efficient image acquisition in small chambers where other documentation methods (like laser scanning and traditional photogrammetry) are not feasible due to space restrictions. Laboratory tests have demonstrated the system's capability to achieve metric precision of approximately ±1–2 cm, making it a reliable tool for confined-space documentation. By offering high-resolution imaging and the ability to generate 3D models with minimal intervention, this system represents a significant step forward in the field of confined-space documentation, with applications ranging from industrial inspections to heritage preservation.
Implementation of coded targets for metrology applications in MicMac, a free open-source photogrammetric software
Authors: Muller Jean-Michael , Daakir Mehdi , Pierrot Deseilligny Marc , Barcet Florian
Published: December 2024

Abstract. Image-based metrology is an increasingly utilized technique across a wide range of industrial applications, largely due to its reliance on precisely measurable and automatically detectable patterns within images. In photogrammetry, coded and uncoded targets, such as ground control points, are commonly used throughout the photogrammetric processing chain. This study presents recent developments in the integration of coded-targets within MicMac, a free open-source photogrammetric software. These developments were undertaken in collaboration between IGN and CERN for future accelerator alignments using image-based ecartometric measurement. One key goal, addressed in this paper, is the creation of a flexible coded-target generator within MicMac, allowing users to specify various constraints for target generation. Additionally, detection and simulation tools were implemented and evaluated. This paper focuses on the use of a common circular coded-target pattern, and introduces a novel home-made target design optimized for both image measurements and topometric instruments. Results from 2D and 3D simulations, as well as real data, demonstrate performance similar to commercial software solutions using circular coded-target, or even superior in certain configurations using our home-made target pattern. To our best knowledge, MicMac is the only free and open-source software achieving these levels of performance.

Published: December 2024

Abstract. The Leica GS18i visual positioning system, introduced in 2021, uses 3D imaging to measure points beyond the reach of conventional GNSS receivers, such as building façades. By leveraging RTK and PPP GNSS capabilities, it enables continuous image acquisition during surveys. This study assessed its 3D geometric accuracy in both open and complex environments with poor GNSS signals. Two field tests at Vindolanda Roman Fort and Newcastle University’s Quadrangle Gateway served to evaluate processing results within the proprietary Leica Infinity and Agisoft Metashape. Results demonstrated 3D RMSEs of ca 3.5 cm in RTK mode without GCPs and 2.5 cm when all images are triangulated with a single GCP. The system achieved consistent cm-level accuracy and precision under challenging conditions with sufficient initial GNSS RTK image orientation. Comparative analyses with Canon DSLR datasets highlighted the GS18i system’s efficiency, though software differences emerged.

Marx y Epicuro: dialéctica del átomo y clinamen
Authors: Blanco Rodríguez Ricardo Alberto
Published: December 2024

Este trabajo pretende exponer la recepción del atomismo de Epicuro y la reinterpretación dialéctica de la teoría del clinamen en la tesis doctoral de 1841 de Karl Marx, con el propósito de extraer algunas aportaciones para una teoría de la libertad. Para ello se analizan las implicaciones del enfoque dialéctico marxiano aplicado a la declinación epicúrea a la luz de las aportaciones del pensamiento filosófico de Schiller y la fenomenología hermenéutica de Ricoeur. Marx descubre en Epicuro una “ciencia de la atomística” en la cual el clinamen es la autodeterminación formal del átomo respecto de la materia; su ley interna, por medio de la cual se abre la posibilidad de una libertad humana que transgrede el determinismo. Se intenta mostrar que causalidad natural y libertad no son excluyentes en un materialismo idealista como el epicúreo, en el que, conforme a la interpretación de Marx, idea y materia se integran en una síntesis dialéctica.
Foucault, la experiencia colonial y el racismo. Notas para descolonizar el archivo
Authors: Sacchi Emiliano
Published: December 2024

Como ha sostenido a Achile Mbembe el descentramiento o la provincialización de Europa abre nuevas posibilidades para el pensamiento crítico. Interrogarse por la potencialidad del pensamiento foucaulteano para dar cuenta de nuestra actualidad, y particularmente desde Latinoamérica, implica partir de este hecho fundamental. En este contexto, caracterizado por el devenir negro del mundo, y a partir de las críticas formuladas por diversos autores de las perspectivas de- y pos-coloniales, se ha abierto la pregunta por el carácter eurocéntrico del pensamiento de Michel Foucault. Así como Nancy Fraser ha señalado la “morada oculta” de Marx y ha extraído de ella una crítica radical del capitalismo, consideramos que es necesario, señalar la “morada oculta” de la genealogía del poder en Foucault. En ese sentido, el artículo interroga la elisión de la experiencia colonial en la arqueo-genealogía del Hombre moderno, en las genealogías de las tecnologías de poder disciplinarias y biopolíticas, cómo en la analítica de la gubernamentalidad neoliberal. Finalmente, el trabajo busca reconocer la potencialidad del pensamiento foucaultiano y señalar, al mismo tiempo, la necesidad de descolonizar su archivo.
El pensamiento político de Miguel de Unamuno: su relación con el liberalismo
Authors: Garrido Ardila J. A. , Gordo Piñar Gemma
Published: December 2024

Los estudios recientes sobre el pensamiento político de Unamuno han venido adscribiéndolo al liberalismo sin insertar su pensamiento en el desarrollo histórico del pensamiento liberal. Es por ello por lo que en este artículo acometemos una revisión del liberalismo de Unamuno, ubicando sus ideas en la historia del pensamiento liberal. Ello nos llevará a matizar las etiquetas políticas que se han puesto a Unamuno, así como a alcanzar las siguientes conclusiones: 1) Unamuno carecía de un conocimiento profundo del liberalismo según éste se consolidó en la filosofía política de su tiempo; 2) su liberalismo oscila entre el liberalismo social y el liberalismo individualista, 3) propendiendo en los años treinta al liberalismo individualista de Mill y Spencer, precursor del liberal conservadurismo.
La dimensión cosmopolítica. Ciudadanía, fronteras y extranjería en E. Balibar
Authors: Sainz Pezonaga Aurelio
Published: December 2024

El enlace entre el pensamiento de Balibar respecto a la ciudadanía y su reflexión sobre las fronteras se produce en la intersección entre las ciudadanías de la frontera y las fronteras de la ciudadanía. Una doble vertiente de la ciudadanía, en tanto que autónoma y heterónoma, sostiene esta estructura cruzada. Y en ella prevalece la contradicción de la ciudadanía nacional, la ciudadanía legalmente reconocida solo dentro de las fronteras del Estado nación. La hipótesis de Balibar es que la contradicción de la ciudadanía nacional no es una contradicción lógica entre lo universal de la ciudadanía y lo particular de la nación, sino una contradicción histórica en la que lo simbólico y lo institucional son indisociables. La respuesta histórica a la contradicción histórica se alumbra a través de la dimensión cosmopolítica de la política. En ella, la ciudadanía no va ligada a la nacionalidad sino a la extranjería.

Red spinach is one of the vegetable horticultural crops used for its leaves. Red spinach cultivation generally uses chemical fertilizers and pesticides because the impact is felt more quickly, but the use of chemical fertilizers and pesticides causes a decrease in productivity. One of the efforts to improve the quality and productivity of red spinach plants can be done by adding organic materials, such as substitutes for chemical fertilizers and pesticides, namely animal manure fertilizers and vegetable pesticides. The purpose of the study was to determine the response of giving types of organic fertilizers and vegetable pesticides to the production of red spinach plants. A Factorial Randomized Group Design (RAK) method, which is divided into three levels and has two factors, was used in this study. Types of animal manure fertilizer and plant-based pesticides were the first and second factors. Types of animal manure fertilizers used: cow manure, vermicompost fertilizer and guano fertilizer. Vegetable pesticides used: biomoxa, neem oil extract and MS. Fisher's variance (F test at 5% level) was used to analyze the observation data. If significant differences were found, then the Least Significant Difference Test (BNT 5%) was continued. The best results in this study were obtained in the treatment of cow manure and vegetable pesticide Neem oil extract.

Brassica juncea L., sometimes known as mustard greens, are annuals with fibrous roots that extend in all directions from the soil surface without producing a crop. Green mustard is one of the most commonly consumed vegetables and is in great demand by the wider community. The amount of mustard produced is not proportional to the high consumption of this vegetable in Indonesia. Therefore, to support sustainable agriculture, efforts need to be made to increase mustard productivity, including the use of microorganisms such as PGPR and environmentally friendly cultivation techniques. The objective of this study was to determine the effect of different types of PGPR on the development and yield of mustard. A standardized Randomized Group Design (RAK) was used in this study. To determine if there were significant differences, the data from the observations were analyzed using the Fisher test (F test at the 5% and 1% levels). Otherwise, the 5% Least Significant Difference test was used. The best results of PGPR types on the growth and production of green mustard plants were obtained in the treatment of PGPR types of Pseudomonas flurescens sp. bacteria compared to other treatments.

Mustard pakcoy is one of the easiest vegetables to grow. The demand for pakcoy is increasing as the number of Indonesian people continues to grow. However, the demand for pakcoy is inversely proportional to its production in the field. Currently, farmers in Indonesia are beginning to understand the importance of using organic fertilizers in the cultivation process. In facing environmental challenges, the use of organic fertilizers is considered a more environmentally friendly alternative compared to chemical fertilizers. This research identifies types of liquid organic fertilizers (POC) that are not only effective but also contribute to environmental sustainability. It aimed to determine the response of POC application on the growth and productivity of pakcoy mustard. This study applied a one-factor Randomized Group Design method with seven levels repeated four times. The factor is the type of liquid organic fertilizer including: no treatment, Biotani Plus, Nasa, Bio Conversion, NaturGen, Eco Fresh, and Explant PHC. The research observations were plant height, number of leaves, wet weight per sample plant, wet weight per plot and wet weight per hectare. The data obtained from the observations were calculated by analyzing the Fisher's test variance at the 5% and 1% levels, if significantly different, it was continued with the 5% BNT test. From the research, it was found that the provision of POC Biotani Plus gave the best results among other types of POC on the growth and yield of pakcoy mustard greens.

Formative assessment, a cornerstone of competency-based teaching, plays a pivotal role in enhancing learner progress. In Vietnamese schools, its potential for driving educational transformation is ripe for exploration. This research delves into the innovative use of Microsoft Forms as a digital tool for designing formative assessment tools for 7th-grade mathematics, with a focus on key mathematical concepts in the curriculum. The study adopts a robust mixed-method approach, combining qualitative and quantitative analyses. It engaged 116 7th-grade students from secondary schools in Quang Ninh, Phu Tho, Nam Dinh, and Thai Binh provinces. Additionally, semi-structured interviews were conducted with 30 mathematics teachers from the same regions, providing deep insights into the practical application of this technology. The findings highlight the significant impact of Microsoft Forms in fostering effective formative assessment. Teachers can anticipate student difficulties, identify common errors, and respond with timely, tailored interventions. Students, in turn, show heightened interest and confidence in the classroom, embracing mathematical concepts with enthusiasm. The research also introduces two innovative techniques to enhance the skills of both teachers and students in leveraging Microsoft Forms effectively. This study underscores the transformative potential of digital tools in modern education, particularly within the framework of Vietnam’s 2018 General Education Curriculum for mathematics. It concludes by recommending the broader adoption of Microsoft Forms across diverse teaching scenarios, signaling a new era in math education where technology bridges gaps and unlocks student potential.

Background: Chronic kidney failure can cause psychological, physical and social activity disorders. Therapy that can preserve the kidneys is hemodialysis. Purpose: This study aims to determine the relationship between duration of hemodialysis and care dependency in CKD patients undergoing hemodialysis therapy. Care dependency was measured using the Care Dependency Scale (CDS). Method: The design of this research is descriptive quantitative with a cross sectional approach. The variables in this study are duration of hemodilsis and care dependency. The research sample was 109 respondents taken using a consecutive sampling technique. Data were analyzed using the Chi Square test. Results: The research results show that there is no relationship between the length of hemodialysis and care dependency with a p value > 0.05, which means there is no relationship between care dependency and the length of hemodialysis. Conclusions: Patients who have been undergoing hemodialysis for a long time will tend to have mild or moderate levels of stress, because of the length of time undergoing hemodialysis, patients are able to adapt themselves to the dialysis equipment and hemodialysis patients will find it easier to manage physical limitations in their daily lives.

Published: December 2024

Cancer related fatigue often begins before the cancer is diagnosed, worsens during the course of treatment and may persist for months – even years- after the treatment ends. Currently, studies are more focussed towards managing these physical symptoms using physical therapy, complimentary therapies and alternative therapies such as yoga, mindfulness meditation, and physical therapy including progressive muscle relaxation technique to reduce their adverse symptoms and enhance their quality of life. As this technique is simple to learn, has no negative impact and is feasible to perform anywhere so it is used on a large scale. Hence the aim of the review is to find out the effects of progressive muscle relaxation technique on cancer related fatigue symptoms in patients receiving chemotherapy and radiotherapy.

Type D is a type of distressed personality first coined in the 1990s by Johan Denollet, which is majorly associated with coronary heart disease. Within the economic context, along with type-D personality, the disease burden of coronary heart disease is quite high, which results in affecting the treatment process and decrease therapeutic response. So, a study to assess the occurrence of type-d personality and economic burden among patients with coronary heart disease, in a selected hospital, Kolkata, West Bengal was conducted with the aim to assess the occurrence of type-d personality and economic burden among patients with coronary heart disease. Descriptive survey approach was used to collect data from 184 patients selected by non-probability convenience sampling technique. One standardized tool DS-14 scale questionnaire, structured checklist was administered by self-report method to collect data. Findings revealed that out of 184 patients, 35 (19.02%) of them had type-d personality and 118 patients (64.13%) had low economic burden. Correlation co-efficient showed that type-d personality and economic burden had negative low correlation. Computed χ2 showed significant association between type-D personality and selected variables like age, length of hospital stays and family history of psychiatric illness and significant association was also found between economic burden and selected variables like educational status, occupational status and monthly family income. Present study had several implications in nursing practice, education, administration and research. The study recommends to conduct this same study on a larger population and in government set up.
