Green Acts: Global Politics vs Local Crises (A Case Study in Two Bulgarian Villages)
Authors: Todorova Rosalina
Published: December 2024

As the EU implements measures to tackle the climate emergency on a continental scale, national governmental and economic actors haste to claim better positions in an eco-friendly low carbon market of goods and resources. With this gradual change, surprising factors hinder local community support for the de-carbonized promised future. In order to understand what inspires rural communities to contest and negate green economic action, I investigate a case of local unrest against the erection of an RES plant on public non-arable agricultural land. Drawing upon in-depth interviews with local villagers, rebelling against the photovoltaic plant and municipal representatives, deciding the fate of the land, I outline three main axes of exclusion. These, I argue, fuel the opposition to the EU’s green acts: the symbolic exclusion of differing types of greenness (natural vs political); the geopolitical political exclusion of the local human for the benefit of the global one; the local exclusion, depriving some citizens of legitimate instruments for social claims-making.

Authors: Stancheva Mila
Published: December 2024

The paper presents some of the results of an ongoing anthropological study on the socialization of “green” and “sustainable” practices, both in business operations and in citizens’ daily lives. We shed light on controversial aspects of sustainability through presenting and analyzing examples of Bulgarian businesses and their leaders, including freelancers, all of whom explicitly link their work to sustainability. The article focuses on the role of consumption as the main channel for transmitting “green“ messages and policies, thereby altering individuals’ attitudes and behavior, and on how these processes unfold in a digital environment, particularly, and in the broader context of the implementation and socialization of the European Green Deal – a set of political initiatives of the European Commission launched in its efforts to lead the continent to climate neutrality by 2050.

Published: December 2024

Background: Cardiovascular disease (CVD) remains a leading cause of morbidity and mortality worldwide, particularly in rural areas. Despite advancements in medical management, rural populations face significant disparities in the prevention and treatment of acute cardiovascular events, such as acute coronary syndromes (ACS). Methods: This narrative review synthesizes current literature on the roles of nursing and pharmacy teams in prehospital emergency care for acute cardiovascular events in rural settings. A targeted literature search was conducted using PubMed and Google Scholar, focusing on rural-urban disparities in cardiovascular care, risk factor management, and healthcare access. Results: The review highlights critical gaps in the availability of specialized healthcare services and the under-treatment of cardiovascular patients in rural regions. Factors contributing to these disparities include socioeconomic challenges, lower health literacy, and limited access to healthcare resources. Innovative strategies, such as the integration of telehealth and interprofessional collaboration among nursing and pharmacy teams, are shown to improve patient outcomes. Effective prehospital interventions can significantly reduce delays in treatment, ultimately enhancing survival rates for acute cardiovascular events. Conclusion: Addressing the healthcare disparities faced by rural populations requires a multidisciplinary approach that includes enhanced training and support for nursing and pharmacy teams.

Published: December 2024

Por su ubicación en la costa del Pacífico Sudamericano, el Perú se encuentra permanentemente expuesto al peligro sísmico. Las extendidas prácticas de construcción informal sin estándares técnicos de diseño sismo resistente, suponen una vulnerabilidad que aumenta los riesgos asociados este peligro. La presente investigación tuvo por objetivo identificar las condiciones de vulnerabilidad sísmica más frecuentes en la construcción de viviendas, empleando un método cualitativo basado en la observación visual. Se tomó una muestra de   403 viviendas del distrito del Rímac en la ciudad de Lima, Perú, en el año 2023, sin considerar la zona declarada como Patrimonio Mundial por UNESCO. Como instrumento se empleó una ficha de observación diseñada para el registro visual desde la vía pública, sin tener que acceder a las viviendas. Se concluyó que entre las principales condiciones de vulnerabilidad observadas se encuentran la ausencia de juntas sísmicas (89.33%), la diferencia de nivel de losas entre edificaciones vecinas (59.8%) y la construcción de muros de ladrillo de baja densidad (60.30%). La interacción de estas condiciones entre viviendas contiguas, puede suponer efectos catastróficos para las edificaciones y aumentar el riesgo de pérdida de vidas ante un evento sísmico, por lo cual se recomienda incidir en estos puntos en programas educativos para la población sobre la importancia de las buenas prácticas constructivas.

La colonización del tiempo: de la imposición judeocristiana a la mercantilización capitalista
Authors: Palazio Galo Edgar
Published: December 2024

La concepción del tiempo ha influido profundamente en la organización de las sociedades humanas. En Occidente, se concibe de manera lineal, avanzando desde el pasado hacia un futuro predeterminado. Esta visión permea la cultura, la religión y la ciencia, pero contrasta con concepciones cíclicas que existían en las sociedades precoloniales. Estas culturas, como la maya, hindú y africana, concebían el tiempo como un ciclo ligado a la naturaleza, con ritmos  de renovación conectados a la vida agrícola, rituales y la cosmología. El colonialismo europeo impuso su visión lineal del tiempo, considerada como símbolo de “progreso” y utilizada para justificar la dominación sobre las sociedades  consideradas “primitivas”. Esta imposición reemplazó las formas cíclicas de medir el tiempo, afectando las  organizaciones sociales y espirituales de las sociedades colonizadas. A su vez, el capitalismo exacerbó esta  dinámica, transformando el tiempo en una mercancía explotable y acelerando los ritmos de vida. Sin embargo, las  visiones cíclicas del tiempo siguen siendo relevantes, ofreciendo una crítica al progreso occidental y proponiendo alternativas que valoran la conexión con la naturaleza y la espiritualidad. Estas perspectivas pueden ser fundamentales para desarrollar  sociedades más justas y sostenibles en la actualidad. En este ensayo crítico, exploramos cómo Occidente impuso su narrativa temporal a las sociedades precoloniales y examinaremos las consecuencias de esta imposición en términos de pérdida cultural, alienación y desigualdad.

Research on Crop Planting Strategies Based on K-means Clustering and Optimisation Models
Authors: Yuan Tianyu
Published: December 2024

This paper investigates the strategy of optimisation model for rural crop cultivation with a view to develop the best cultivation plan for the next seven years. An optimisation model with the objective of profit maximisation has been developed by taking into account the expected sales volume, acreage, cost of cultivation and selling price of various crops and their uncertainty risks. The model incorporates the complex constraints of the actual production process and takes into account multiple uncertainties such as changes in market dynamics and fluctuations in climatic conditions by analysing four scenarios, namely optimal, suboptimal, intermediate and stochastic, which makes the model much more practical. In addition, this paper applies the K-means clustering method to explore the substitution and complementary relationship between different crops, which makes the model more in line with the actual market law. The results show that a reasonable planting strategy can not only enhance the economic benefits of crops, but also promote the efficient use of resources and sustainable development of the environment. The optimisation model proposed in this paper provides scientific guidance for agricultural decision makers and provides a reference for the production strategies of other products. Future research can be further extended to other regions and crop types to improve the overall strategic layout of agricultural production and promote the high-quality development of agriculture.

An Exploration of Learning Methods for Manchu Songs Based on the Oral Characteristics of the Altaic Language Family
Authors: Zang Yimin
Published: December 2024

Amid the wave of globalization, music, as a language without borders, is transcending geographical and cultural boundaries at an unprecedented pace, intimately connecting melodies and emotions from all corners of the world. In this process, folk songs with distinct characteristics have emerged as significant bridges connecting diverse cultures. They not only carry the sentimental attachments and historical recollections of their own ethnic groups, but they also fuel the curiosity of music lovers around the world to discover new sounds. Among these, Manchu songs have captured the interest of many students due to their distinct phonological appeal. But pronunciation discrepancies present a significant obstacle to learning Manchu songs, especially for learners whose native tongue is not Altaic, where the difficulties are numerous.Manchu is an Altaic language family member, and as such, its pronunciation differs greatly from that of many other European or Asian language families. This distinction can be seen in the rules governing syllable combinations, tone fluctuations, and the arrangement of vowels and consonants. Consequently, when learners attempt to mimic Manchu songs using their native language or familiar linguistic habits, they often mispronounce lyrics or fail to achieve accurate pronunciation. For instance, certain consonants in Manchu may be absent in Chinese or other non-Altaic languages, rendering it difficult for learners to grasp their essence during pronunciation, thereby affecting the overall performance of the song.

Authors: Zhao Lubing
Published: December 2024

As environmental awareness increases and new energy technologies develop, microgrid systems have garnered significant attention as an important method for operating new energy sources. This trend reflects the growing emphasis on environmental protection. In the process of achieving both independent operation and grid-connected operation, the internal microgrid needs to incorporate an inverter control system equipped with various control methods. The inverter control system is responsible for regulating the inner loop parameters, and the coupling of these parameters will directly impact system stability. The research focus of this article is on microgrid systems that include wind-solar-storage systems. The study primarily employs three control types—constant power control (PQ), virtual synchronous generator control (VSG), and a combination of PQ and VSG control (PQ+VSG)—for simulation analysis to explore system stability. By conducting an in-depth stability analysis, we further understand the characteristics of inverter internal control and grid-connected inverter operation, thereby providing guidance for the design of control systems and ultimately achieving their effective application in power systems.

Based on the context of a power exchange station, this paper describes the charging and discharging circuit of V2G technology and its working principle, and uses MATLAB/Simulink to build a typical three-phase rectifier and active inverter circuit and observe and analyze its waveform. In the battery swap station, it can not only avoid the adverse impact on the power grid due to the large number of electric vehicles connected to the grid in an uncontrolled manner, but also enable vehicle owners to have a simpler and more convenient experience of changing batteries, which is a major trend for future development.
Research on an Elderly Indoor Fall Detection System Based on IoT and Computer Vision Technology: Integration and Performance Analysis of YOLOv5 and OpenPose
Authors: Wang Yaokai
Published: December 2024

The rapid growth of the global elderly population has led to an increased need for efficient and reliable fall detection systems to ensure timely medical assistance. Traditional monitoring methods, such as wearable devices and environmental sensors, often face challenges in accuracy, reliability, and user compliance. This study proposes an indoor fall detection system for the elderly, integrating Internet of Things (IoT) and computer vision technologies, specifically utilizing YOLOv5 and OpenPose algorithms. YOLOv5 is employed for rapid and accurate human body detection, providing position information by computing the center of objects in frames or videos. OpenPose is then used for detailed real-time pose estimation, detecting 135 key points on the human body—including hands, face, and feet—to assess whether a fall has occurred based on posture analysis. The system was tested using two datasets, GMDCSA and URFD, achieving sensitivity values of 0.9412 and 0.9583, respectively, indicating high accuracy in fall detection. The false positive rates were 0.0588 and 0.2857, while the false negative rates were 0.0588 and 0.0417, demonstrating the system's reliability in minimizing detection errors. The integration of YOLOv5 and OpenPose leverages their combined strengths in object detection and pose estimation, resulting in a robust solution suitable for real-time applications.

Published: December 2024

With the increasing global awareness of environmental protection and the accelerated transformation of energy structures, the new energy vehicle (NEV) industry has become a crucial strategic choice for governments worldwide to promote green economic development and achieve carbon reduction goals. In China, the "dual-credit" policy and other measures have been implemented to actively drive technological advancements and market expansion in the NEV industry. This study employs the difference-in-differences (DID) method to systematically examine the mechanism by which the "dual-credit" policy impacts firms' innovation performance through empirical analysis. Furthermore, it incorporates R&D investment as a mediating variable to explore the indirect effect of policy incentives on firms' innovation performance. The findings reveal that the "dual-credit" policy significantly promotes corporate innovation and effectively enhances innovation performance by increasing firms' R&D investment levels, thereby amplifying the policy's effectiveness. This research provides empirical support for the optimization of NEV industry policies and offers theoretical and practical references for advancing industrial technological upgrades and achieving green economic development goals.

This study aims to construct a method to measure the operational efficiency of SMEs based on DEA-PCA model. Through theoretical elaboration, model construction, indicator selection, empirical analysis, and result discussion, it reveals the characteristics and influencing factors of SMEs' operational efficiency, and provides theoretical basis and practical guidance for enterprises to improve their operational efficiency. The study shows that this method can effectively overcome the subjectivity of the traditional DEA method in the selection of indicators, and provide strong support for the accurate assessment of the operational efficiency of SMEs.
China-ASEAN Collaborative Governance of Energy Transition under the Belt and Road Initiative: Status, Challenges and Approaches
Authors: Li Yunjie
Published: December 2024

This paper offers a comprehensive analysis of the collaborative governance practices between China and the Association of Southeast Asian Nations (ASEAN) in the realm of energy transition. It examines how the actions of Chinese energy-related entities have fostered political trust among ASEAN member states under the Belt and Road Initiative (BRI). The process of energy transition is characterized by its regional nature, high investment, and prolonged transition period. ASEAN member states have demonstrated a commitment to achieving regional energy transition, yet they are deficient in the critical elements necessary to translate proposals into actionable practices.  Supported by the BRI, various spatial levels of Chinese entities have entered ASEAN to participate in cooperative governance of energy transition. The cooperation between the China-ASEAN community on the issue of energy transition has enabled an orderly and efficient progression of energy transition in Southeast Asia. Concurrently, it has bolstered the trust of ASEAN member states in China, reducing their indecisiveness in regional affairs.

Published: December 2024

Hybrid particle swarm optimization (PSS) is an intelligent optimization method widely used in machine learning. In this paper, we combine evolutionary game theory and particle swarm optimization and apply them to the optimization of farm planting strategies. Firstly, a linear regression model was established by accurately modeling the output, sales volume and other relevant indicators of agricultural products. Then, by using the powerful global search ability of game theory and hybrid particle swarm optimization to solve the optimal solution under constraints. Subsequently, the Monte Carlo method is introduced to incorporate factors such as climate and geographic location into the model, which further improves the accuracy of the prediction. This study not only successfully applies game theory and hybrid particle swarm optimization to the optimization of farm planting strategy, which has high practical value, but also provides a useful reference for similar multi-dimensional programming problems.
