Aproximación a los procesos de exclusión social a partir de la relación entre el territorio y la movilidad cotidiana
Authors: Cebollada i Frontera Àngel
Published: December 2024

Este artículo analiza la relación existente entre la movilidad cotidiana y la exclusión social. El modelo de movilidad hegemónico basado en el uso del coche se revela como selectivo, puesto que su utilización es desigual según la adscripción social de los individuos. Mujeres, jóvenes e inmigrantes son tres de los colectivos con unos índices de motorización menores. La menor disponibilidad de vehículo privado reduce las posibilidades de uso de la ciudad a estos colectivos. En este contexto, las características del territorio urbano se revelan determinantes para extender la igualdad de oportunidades de uso de la ciudad. Se establecen tres categorías de territorio según su capacidad de inclusión social: incluyentes, semiincluyentes y excluyentes. Finalmente, la exclusión del mercado laboral resultado del déficit de accesibilidad ilustra la desigualdad de oportunidades de los colectivos menos motorizados y la importancia de las características urbanas en la búsqueda de mayores cotas de inclusión social.
Localització dels conreus irrigats de la plana de l’Alt i el Baix Empordà a través de l’anàlisi geohistòrica i de la teledetecció
Authors: Serra Ruiz Pere
Published: December 2024

Les comarques empordaneses presenten un dels paisatges agraris més diversificats i apreciats de Catalunya. L’article constitueix un exemple d’ús conjunt en l’anàlisi agrícola de dues disciplines ben diferenciades fins a l’actualitat: la geohistòria i la teledetecció. D’una banda, la geohistòria ha permès analitzar les transformacions humanes i les repercussions en els conreus més significatives de les planes de l’Alt i del Baix Empordà des del segle XVIII. A causa de la similar estructura geofísica i d’evolució geohistòrica, per exemple amb les dessecacions d’estanys i llacunes o amb les desviacions dels trams finals dels cursos fluvials, les dues planes han estat tractades conjuntament. D’altra banda, la teledetecció a través d’imatges de satèl·lit ha permès cartografiar els conreus de l’any 2004 amb una elevada fiabilitat, gràcies al mètode emprat i a l’anàlisi geohistòrica.
La ecología política urbana: una disciplina emergente para el análisis del cambio socioambiental en entornos ciudadanos
Authors: Domene Gómez Elena
Published: December 2024

La ecología política urbana es una disciplina emergente que proporciona un enfoque multidisciplinario y una metodología innovadora para el análisis del cambio socioambiental que tiene lugar en asentamientos urbanos. Según ésta, las mayores barreras para conseguir «ciudades sostenibles» son también políticas, y los objetivos y las posibilidades de conseguirlos están sujetos a relaciones de poder. Por tanto, estos objetivos deberían ser alcanzados mediante, por un lado, el análisis de los condicionantes políticos, sociales, económicos, culturales y ambientales que producen un determinado paisaje urbano, y, por otro lado, a través del examen de la estructura y la organización de las relaciones de poder y la expresión social e institucional de estas relaciones. Por ende, la pregunta cambia de cómo conseguir ciudades sostenibles a cuáles son las condiciones que promueven la adopción de determinadas «prácticas sostenibles» sobre otras.

Published: December 2024

A diabetes mellitus tipo II (DM2) e a hipercolesterolemia frequentemente coexistem em pacientes, elevando o risco de complicações cardiovasculares e desafiando o manejo clínico integrado. O presente artigo de revisão integrativa explora as interações entre o controle glicêmico e a regulação da enzima HMG-CoA redutase, eixo fundamental na síntese de colesterol, especialmente sob o uso de medicamentos a base de estatinas – agentes hipolipemiantes amplamente prescritos para pacientes com dislipidemias. Evidências sugerem que, embora as estatinas sejam eficazes na redução dos níveis de colesterol, seu uso pode impactar na homeostasia glicêmica, exacerbando a resistência à insulina e aumentando os níveis de glicose em indivíduos com DM2. Sob tal conjuntura, esta revisão visa discutir, criticamente, os benefícios e os desafios do uso de estatinas em pacientes com DM2 e hipercolesterolemia, destacando estratégias que busquem minimizar o impacto sobre os níveis glicêmicos sem comprometer o controle do metabolismo lipídico. Conclui-se que uma abordagem integrada e individualizada é essencial para otimizar os resultados terapêuticos e para reduzir os riscos de complicações cardiovasculares e metabólicas nestes pacientes.

Tecnologias como os organominerais, associados a bactérias promotoras de crescimento de plantas, mostra ser promissoras para aumentar a eficiência da fertilização. O presente trabalho objetivou-se avaliar a eficiência de adubos de liberação diferenciada associados a bactérias promotoras de crescimento de plantas no estabelecimento e produtividade do tomate cereja, bem como seus efeitos residuais no cultivo do milho plantado em sucessão. O delineamento experimental adotado foi em blocos casualizados em esquema fatorial 3x4x2, com três repetições, totalizando 72 parcelas com 2 plantas cada. Os tratamentos foram compostos por 3 fontes de adubos (mineral convencional; organomineral farelado e organomineral granulado), 4 doses (0% - tratamento controle; 50%; 100% e 200%) equivalente à adubação de N, P e K recomendada para o ciclo do tomate e 2 condições de associação com bactérias promotoras do crescimento de plantas (BPCP), através da adição ou não. Avaliaram-se as variáveis repostas de produtividade total, produtividade comercial, número de fruto total/número de fruto comercial e teor de nutrientes (N, P, K) das plantas de tomate, além de número de espigas/planta e peso dos grãos para cultura do milho. Dentre as fontes testadas, o fertilizante organomineral granulado apresentou melhor desempenho nos parâmetros avaliados, principalmente na dose de 100% da recomendação. Quando houve adição de BPCP os resultados foram ainda superiores, apresentando vantagem significativa para todas as variáveis avaliadas, demonstrando ser uma alternativa viável aos fertilizantes comumente utilizados.
UPP: An Investigation into the Effectiveness of ChatGPT-Generated Lesson Plans in Vocational Education
Authors: Deguara David , Gatt Thomas , Said Pullicino Gerard , Scerri Daren
Published: December 2024

With the growing integration of artificial intelligence (AI) in education, understanding its pedagogical implications has become an imperative. Unpacking Pedagogical Potential (UPP) is a study that addresses this need by exploring the efficacy of artificially generated lesson plans in the context of a modern vocational programme. The research aims to evaluate the quality and comprehensibility of these AI-driven lesson plans and teachers’ experiences. Associated benefits and challenges will also be identified. Data will be collected through a grounded theory approach, including interviews, focus group discussions, and performance evaluations. The objective is to present a holistic view of the pedagogical potential of AI in lesson planning, ultimately guiding future enhancements for AI applications in educational contexts. In the first phase of the study, two lesson plans were generated on the challenging topics of interfaces and abstraction in object-oriented programming. The lesson plans were generated using OpenAI’s GPT-4 through a one-shot prompt detailing the template to be used. Following generation, the lessons plans were peer-reviewed and evaluated using Lesson Plan Analysis Protocol (LPAP). Analysis of the score and a critical narrative of generation process was performed. Results show that even though lesson plans were generated by ChatGPT, the lesson plans require extensive human intervention to make the activities viable for use in the classroom. On the other hand, using them to structure the information presented is a viable way to ensure that the teacher follows a pre-established structure in generating a lesson plan. This can serve to therefore improve the quality of lesson plans generated by experienced teachers based on a standard metric.
Emerging Terrains for Dialogue, between Learner and Educator? A Narrative Inquiry
Authors: Callaby Floridia David
Published: December 2024

A term that has become synonymous with young people today is anxiety. This term seems to permeate through the personal, social, professional, academic, and technological domains of their lives. Coping mechanisms have been strained through the course of the COVID-19 pandemic, and educational contexts must resolve to provide young people with a holistic education that matters to them, and that fulfils its role in preparing young people for work and for life. Taking the non-formal aspect of education as a building block for doing this, the research delves into the personal domain as a means for accompanying young people through their learning journeys in MCAST. The researcher met with eight students and conducted two focus groups analysing texts using narrative thematic analysis. Data collection happened by discussing together with the participants a set of eight themes, making up an initial conceptual framework from a previous study. The findings of the research demonstrate a convergence with the various categories of the conceptual framework. These findings therefore make recommendations on the need to support learners attending higher education in the personal domains of their lives.
Prolegomena to the scientific and practical approach to security culture in psychosocial aspects - selected issues
Authors: Piwowarski Juliusz , Trifunović Darco , Woszczek Leszek
Published: December 2024

The content of this article refers primarily to the design phase of the scientific research process on the theoretical and practical aspects of psychosocial approaches to the essence of security culture functioning. The component on the essence of the functioning of the human psyche considered as a subject of security, is nowadays in a not extensive enough presence in the theory and research, and further – also in the implementation of research results – in the style of action and cooperation for security either completely formalistic – or not emancipated from the impact that results from the application and introduction into science and practice of the spirit of the humanistic factor postulated to be taken into account by Znaniecki in the social sciences. The authors want to make clear to the social environment of security researchers the fact that the human psyche component is absent from NoB to the extent that could be considered adequate to the existing scale of security needs in humans.

Authors: Abiola Oyeronke Akintobi  , Ifeanyi Chukwunonso Okeke  , Olajumoke Bolatito Ajanin
Published: December 2024

Tax evasion and fraud are significant global challenges that undermine public finances, erode trust in tax systems, and exacerbate socioeconomic inequalities. Traditional methods for addressing these issues often fall short due to their inefficiencies and susceptibility to manipulation. This paper explores the transformative potential of blockchain technology and artificial intelligence (AI) in combating tax evasion and enhancing transparency in tax administration. Blockchain’s core features, such as decentralization, immutability, and real-time transaction tracking, offer innovative solutions for secure tax record management and fraud prevention. Similarly, AI’s capabilities in data analysis, pattern detection, and audit automation present new opportunities to identify and mitigate fraudulent activities. The paper also examines the challenges and ethical considerations associated with implementing these technologies, such as infrastructure demands, data privacy, and algorithmic bias. Recommendations are provided for policymakers, including modernizing tax infrastructure, fostering public-private partnerships, and promoting international cooperation. By leveraging blockchain and AI responsibly, tax authorities can revolutionize tax governance, enhance compliance, and rebuild public trust in taxation systems.

A study was conducted regarding the factors and effects of the average rate of profit in Bulgaria. The main variables on which this paper focuses are introduced in the beginning – those being the average rate of profit, the average organic composition of capital, the average rate of surplus value, the growth rate of the labour force, and the growth rate of the GDP. The proposed hypotheses’ validity was analysed. The average rate of profit was found to have an upward trend, while a significant linear negative relationship was found between the average rate of profit and the average organic composition of capital; a statistically insignificant positive linear relationship was found between the growth rate of labour and the average rate of profit; a stronger yet not significant enough correlation exists between the labour force growth rate at a time t+1 and the average rate of profit at time t; there is a significant positive linear relationship between the average rate of profit and the GDP growth rate; and a significant correlation was found between the average rate of profit and the average rate of surplus value.
THE IMPACT OF MULCH-TILL TECHNOLOGY ON AGRICULTURE
Authors:   University of National and World Economy, Sofia, Bulgaria, Blagoev Anton
Published: December 2024

Sustainable agriculture requires increasing human productivity to meet current needs while preserving the ability of future generations to produce food. One of the keys to achieving this is proper soil management, which includes tillage and appropriate soil improvement measures. One of the significant impacts of tillage on the sustainability of the soil environment is manifested through its impact on the soil itself. This includes soil degradation, pollution of water resources, and the release of greenhouse gases associated with soil processes. The need for sustainable solutions is particularly important in areas facing various constraints. This reality highlights the urgent need to implement practices that balance productivity with natural resource conservation. The choice of an appropriate agronomic practice, such as mulch-till technology, complemented by no-till and strip-till, can have a significant positive impact on both agricultural production and the environment. This study focuses on the impact of mulch-till technology as a concrete example of an agri-environmental practice that aims at soil conservation while contributing to environmental protection. The paper includes a review of existing literature to analyse the concept and application of mulch-till technology. Furthermore, the effects of the introduction of this technology in agricultural activities are considered, and the potential future benefits for sustainable development and environmental protection are assessed.

Published: December 2024

Mosquitoes transmit several deadly diseases such as brain fever, chikungunya, dengue fever, filariasis, hemorrhagic fever, Japanese encephalitis, malaria, dengue, and Zika. While synthetic chemical insecticides are commonly used for mosquito control, they pose significant risks to human health and the environment. As a result, plant-based insecticides have emerged as a promising alternative. Recent studies have shown that green-synthesized silver nanoparticles (AgNPs) derived from plant extracts exhibit potent larvicidal activity. This review highlights the effectiveness of silver nanoparticles in controlling mosquito populations, focusing on 80 plant species with demonstrated larvicidal properties. Among the plants, Annona squamosa, Artemisia nilagirica, and Nelumbo nucifera showed the most significant activity. The green synthesis of silver nanoparticles offers a more sustainable and environmentally friendly alternative to traditional chemical insecticides, providing a valuable strategy for controlling mosquito larvae and reducing the spread of vector-borne diseases.

Представлены результаты расчетного моделирования распространения излучения естественной звезды через турбулентную атмосферу к телескопу, расположенному на Земле, и получения её изображения с использованием адаптивной оптики. В рамках работы проводится верификация расчетной модели распространения излучения по протяженной турбулентной трассе, заменяемой цепочкой фазовых экранов, моделирующих широкий диапазон пространственных неоднородностей. Для такой цепочки экранов продемонстрировано хорошее согласие между расчетными и аналитическими структурными функциями фазы, что подтверждает надежность расчетной модели. С использованием данной модели исследована точность определения угловой координаты звезды с помощью излучения второй естественной звезды, находящейся за пределами изопланарной области, при различном внешнем масштабе турбулентности. Полученные результаты сравниваются с аналитикой.

The results of computational modeling of the propagation of radiation from a natural star through a turbulent atmosphere to a telescope located on Earth and obtaining its image using adaptive optics are presented. As part of the work, the verification of the computational model of radiation propagation along an extended turbulent path is carried out, which is replaced by a chain of phase screens modeling a wide range of spatial inhomogeneities. For such a chain of screens, good agreement has been demonstrated between the computational and analytical structural functions of the phase, which confirms the reliability of the computational model. Using this model, the accuracy of determining the angular coordinate of a star is investigated using radiation from a second natural star located outside the isoplanar region, at different external scales of turbulence. The results obtained are compared with analytics.

В павильоне лазерной установки «Луч» с помощью датчика волнового фронта Шака-Гартмана экспериментально зарегистрированы динамические серии гартманограмм и волновых фронтов лазерного излучения, прошедшего через турбулентную оптическую трассу. Определена ширина полосы динамических турбулентных искажений Vturb=4 Гц. Динамика турбулентности на инерционном интервале от 2 Гц до 20 Гц соответствует колмогоровскому спектру. Определён радиус когерентности r0 при различном влиянии воздушных потоков на волновой фронт излучения. В условиях специализированного «чистого» помещения его значение составило от r0 =9 см до r0 =39 см (число Штреля от St=0,18 до St=0,75). Анализ пространственной структуры измеренных волновых фронтов показал, что r0 характеризует амплитуду турбулентных искажений волнового фронта.

In the pavilion of the "Luch" laser installation, dynamic series of Hartmanograms and wavefronts of laser radiation passing through a turbulent optical path were experimentally recorded using a Shaka-Hartmann wavefront sensor. The bandwidth of dynamic turbulent distortions Vturb=4 Hz is determined. The dynamics of turbulence in the inertial range from 2 Hz to 20 Hz corresponds to the Kolmogorov spectrum. The radius of coherence r0 is determined for different effects of air flows on the radiation wavefront. In the conditions of a specialized "clean" room, its value ranged from r0 = 9 cm to r0 = 39 cm (the Strel number from St =0.18 to St =0.75). The analysis of the spatial structure of the measured wavefronts showed that r0 characterizes the amplitude of the turbulent distortions of the wavefront.

На основе обработки временных рядов флуктуаций метеопараметров, регистрируемых акустическими метеостанциями, исследовано влияния стратификации на отклонения спектра турбулентности от модели Колмогорова - Обухова в приземном слое атмосферы. При сопоставлении временной динамики характеристики устойчивости (число Монина - Обухова) и показателя степенной модели спектра флуктуаций температуры установлена значимая корреляция между ними. Предложена эмпирическая модель зависимости показателя спектра от параметра устойчивости. Модель позволяет на основе оценок стратификации судить об изменениях параметров спектральной структуры мелкомасштабной турбулентности. Полученная зависимость отражает влияние отклонений от однородных и изотропных условий развития турбулентности, обусловленных стратификацией в приземном слое.

Based on the processing of time series of fluctuations in meteorological parameters recorded by acoustic weather stations, the effects of stratification on deviations of the turbulence spectrum from the Kolmogorov-Obukhov model in the surface layer of the atmosphere are investigated. When comparing the temporal dynamics of the stability characteristic (Monin-Obukhov number) and the exponent of the power model of the temperature fluctuation spectrum, a significant correlation between them was established. An empirical model of the dependence of the spectrum index on the stability parameter is proposed. The model makes it possible to judge changes in the parameters of the spectral structure of small-scale turbulence based on stratification estimates. The obtained dependence reflects the influence of deviations from homogeneous and isotropic conditions of turbulence development caused by stratification in the surface layer.

Для исследования параметров конденсационной активности атмосферных частиц при искусственном изменении относительной влажности воздуха впервые применен диффузионный спектрометр аэрозоля, позволяющий контролировать функцию распределения частиц по размерам в диапазоне диаметров от 2 до 1200 нм. Это дало возможность изучения гигроскопических свойств самых мелких частиц, лежащих за пределами чувствительности нефелометров и фотоэлектрических счетчиков.

For the first time, an aerosol diffusion spectrometer was used to study the parameters of the condensation activity of atmospheric particles with an artificial change in relative humidity, which makes it possible to control the particle size distribution function in the diameter range from 2 to 1200 nm. This made it possible to study the hygroscopic properties of the smallest particles that lie beyond the sensitivity of nephelometers and photovoltaic meters.

Азиатская пыль распространяется на большие расстояния и оказывает значительное влияние на экологию. Кроме природных источников, в возникновении и распространении Азиатской пыли участвует техногенная деятельность. Актуальной задачей является контроль над источниками возникновения экологических загрязнений. Для этого необходимо развитие сети компактных наземных лидарных установок. Предложено для этой цели использовать в лидаре волоконный лазер. Эти лазеры выпускаются рядом фирм, применяются в производстве и обладают повышенной надежностью и стабильностью в эксплуатации. Однако у лазеров серии Q-switch импульс большой длительности и высокая частота повторения. Предложено решение этой проблемы и экспериментально показана возможность применения волоконных лазеров для целей лидарного зондирования.

Asian dust spreads over long distances and has a significant impact on the environment. In addition to natural sources, man-made activities are involved in the occurrence and spread of Asian dust. An urgent task is to control the sources of environmental pollution. This requires the development of a network of compact ground-based lidar installations. It is proposed to use a fiber laser in lidar for this purpose. These lasers are manufactured by a number of companies, are used in production and have increased reliability and stability in operation. However, the Q-switch series lasers have a long pulse duration and a high repetition rate. A solution to this problem has been proposed and the possibility of using fiber lasers for lidar sensing purposes has been experimentally shown.

В данной работе мы решаем задачу рассеяния света в направлении рассеяния назад в рамках приближения физической оптики для четырех типичных форм ледяных частиц перистых облаков: гексагональные пластинки, столбики, пули и дроксталлы в предположении, что эти частицы квазигоризонтально ориентированы в пространстве. Для того чтобы соответствовать техническим характеристикам лидара ATLID, установленного на спутнике EarthCARE, мы использовали длину волны 0.355 мкм, показатель преломления – 1.3249 и угол наклона лазера от зенита 3°. Представленные в докладе результаты могут быть использованы для интерпретации данных, получаемых как при космических, так и наземных лидарных наблюдениях.

In this work, we address the light scattering problem in the backscattering direction within the framework of physical optics for four typical shapes of ice particles in cirrus clouds: hexagonal plates, columns, bullets, and dendrites, assuming these particles are quasi-horizontally oriented in space. To match the technical specifications of the ATLID lidar installed on the EarthCARE satellite, we used a wavelength of 0.355 µm, a refractive index of 1.3249, and a laser zenith angle of 3°. The results presented in the report can be used for interpreting data obtained from both spaceborne and ground-based lidar observations.

Выполнено сопоставление долговременных трендов и межгодовых вариаций содержания NO2 в тропосфере и стратосфере по результатам спектрометрических измерений на станции Звенигород и измерений с помощью спутникового прибора OMI во время пролетов спутника над окрестностью станции в 2004–2020 гг. По тем и другим данным получены и сопоставлены между собой сезонно зависимые оценки линейных трендов и межгодовых изменений NO2 под влиянием 11-летнего солнечного цикла и крупномасштабных циркуляционных факторов, таких как Арктическое колебание, квазидвухлетняя цикличность в экваториальной стратосфере, вариации температуры поверхности океана в центральной и восточной зоне экваториальной части Тихого океана.

A comparison of long-term trends and interannual variations of NO2 content in the troposphere and stratosphere was performed based on the results of spectrometric measurements at the Zvenigorod station and measurements using the OMI satellite instrument during satellite flights over the vicinity of the station in 2004-2020. According to both data, seasonally dependent estimates of linear trends and interannual changes in NO2 under the influence of the 11-year solar cycle and large-scale circulation factors such as the Arctic oscillation, quasi-two-year cycles in the equatorial stratosphere, and variations in ocean surface temperature in the central and eastern zones of the equatorial Pacific Ocean were obtained and compared.
