Description:

Achieving Sustainable Development Goal 2 (Zero Hunger) by 2030 remains a persistent global challenge, especially under current overlapping crises such as climate change, economic instability, and geopolitical conflicts. This study critically analyzes the food security strategies of twelve countries across four income groups, as classified by the World Bank: Low-Income (Malawi, Afghanistan, Ethiopia), Lower-Middle-Income (Nigeria, India, Lebanon), Upper-Middle-Income (Maldives, Brazil, China) and High-Income (Canada, Germany, United Arab Emirates). Using a structured narrative review of national policies and programs (2016–2024) sourced from academic databases, government publications, and international reports, we assess the alignment of strategies with the sustainability pillars (economic, social, environmental) and six key agri-food system interventions. Findings show that lower-income countries emphasize social protection and foundational agriculture (e.g., Ethiopia’s safety net improved food security by 30%), while higher-income nations focus on technological and environmental innovations (e.g., Germany aims to reduce nutrient losses by 50% by 2030). However, 10 of the 12 countries are off track, progressing at less than 50% of the rate needed. China (80% SDG2 score), Canada (70%), and Afghanistan (35%) demonstrate the widespread nature of this trend across varying income groups. The study underscores the urgency for integrated, context-specific strategies, enhanced international cooperation, and financing to accelerate progress toward Zero Hunger.

The Elimination of Illegal Waste in Hungary: New System of Sanctions and the First Results

András Torma Anita Boros Gergely Zoltán Macher

Publication Name: Chemical Engineering Transactions

Publication Date: 2024-01-01

Volume: 114

Issue: Unknown

Page Range: 907-912

Description:

Illegal dumping is a persistent environmental challenge, with limited comprehensive data collection practices across EU Member States, leading to a lack of comparative databases on this issue. This paper addresses the problem by focusing on illegal dumping in Hungary and examining the development of a digital model for monitoring these activities, along with the characteristics and sanctions related to illegal dumping. By exploring waste management practices in the Visegrad Group Member States, this paper highlights the absence of systematic data collection and presents Hungary as a case example where citizens reported over 22,000 cases of illegal dumping in just six months via the WasteRadar application. The research findings underscore Hungary’s recent reforms, which introduced a nationwide database for tracking illegal dumping and imposed stricter sanctions aimed at mitigating the adverse environmental impacts of such activities. These actions signify important strides in addressing illegal dumping and improving environmental governance. This paper highlights the main characteristics of the reform of the Hungarian regulation, such as the advantages of the introduced method, such as establishing a country-wide database on illegal dumping and introducing significantly stricter sanctions on this activity to reduce the harmful environmental effects.

Financing football players’ careers from Africa to Europe: Does it follow a pecking order?

Joseph Ato Forson Ellis Kofi Akwaa-Sekyi Ernest Yeboah Acheampong Ralph Frimpong Fiona Soraya Addai-Sundiata Attila Szabo

Publication Name: Sport Business and Management an International Journal

Publication Date: 2025-11-24

Volume: 15

Issue: 6

Page Range: 657-684

Description:

Purpose – This study examines how professional African footballers finance their international careers and proposes an equitable model for distributing earnings among contributors, using the pecking order theory (POT) as a guiding framework. It seeks to determine whether players’ financing behaviour follows a pecking order and how earnings can be fairly shared among stakeholders to reduce conflict. Design/methodology/approach – Employing a mixed-methods design, the study draws on in-depth interviews with 36 African footballers from across the CAF zones who have played in over 30 professional leagues in UEFA countries. Primary qualitative data is supported by secondary sources, including player profiles, media reports, club websites and academic publications. Findings – The findings reveal that financing players’ careers in Africa follows a pecking order. Footballers initially rely on cheap internal financing sources (family and personal efforts) before turning to external, debt-like and equity-based support (community sponsors, local managers and agents) to pursue professional opportunities abroad. The study proposes a tripartite model for earnings distribution, allocating proportional returns to family, debt contributors and equity stakeholders, based on timing, risk and level of support. This addresses the financing gap and offers a practical solution to disputes over financial entitlements. Originality/value – This research is among the first to systematically apply POT to athlete financing in Africa and propose a model that reflects the informal yet critical roles played by non-institutional actors. By drawing parallels with startup financing, it contributes new theoretical and policy insights into sports migration, career development and conflict resolution in football. It also sets an agenda for further research into athlete financing in other sports and developing regions.

Digital economy and export complexity: unveiling its role in transforming china’s manufacturing industry

Laszlo Vasa Muhammad Ramzan Ummara Razi Guo Qingran Ding Cuicui

Publication Name: Environment Development and Sustainability

Publication Date: 2025-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

The digital economy has become a key driver in transforming and upgrading China’s manufacturing industry. This study contributes to the existing literature by utilizing spatial econometrics on panel data from 31 provinces, autonomous regions, and municipalities across mainland China to capture the regional spatial effects of the digital economy and regional disparities on the technological complexity of China’s manufacturing exports. These areas are often overlooked in prior studies. Unlike prior research focusing on isolated mechanisms, this study simultaneously evaluates three mediating pathways: innovation, human capital, and industrial restructuring, providing a comprehensive understanding of digitalization’s impact on export complexity. The duration of the study spans from 2011 to 2020. The study’s findings reveal that the digital economy’s growth significantly improves the technological complexity of manufacturing exports. It achieves this through three primary channels: promoting technological innovation, enhancing human capital, and advancing industrial structures. Furthermore, the influence of the digital economy on export technology complexity varies by region, indicating regional heterogeneity. Therefore, to foster a strong industrial ecosystem, each region must refine its digital economy environment, elevate development levels, encourage collaboration, and facilitate information sharing, thereby accelerating the digital transformation of manufacturing.

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Electric and hybrid vehicles, similarly to combustion engine ones, can experience malfunctions, yet preventive diagnostics for their electric motors are underdeveloped. While many methods exist for testing electric motors in heavy industry, they are not commonly applied in the vehicle industry. Our study aims to develop a real-time, non-invasive fault detection procedure for electric motors in these vehicles. Previous research has focused on simulations, but our work involves real measurements conducted in a controlled laboratory using a two-axle chassis dyno. We present the hybrid vehicle’s drivetrain, our equipment, and the feasibility of simulated methods, and we also detail the evaluation method used.

Innovative public-health strategies for neurodegenerative disease: leveraging diversified ultraviolet irradiation as a next-generation therapy

U. Saeed Ilker Ozsahin Z. Z. Piracha C. Shao-Chun M. Khan

Publication Name: Brazilian Journal of Biology

Publication Date: 2025-01-01

Volume: 85

Issue: Unknown

Page Range: Unknown

Description:

Neurodegenerative diseases (NDs) such as Alzheimer’s, Parkinson’s, Huntington’s disease, and amyotrophic lateral sclerosis are escalating worldwide, straining healthcare systems and leaving patients with therapies that are largely palliative. Emerging evidence positions diversified ultraviolet (UV) irradiation as a groundbreaking, non-invasive strategy to counter these disorders. Beyond its traditional use in sterilization, specific UV spectra, UV-B (280–320 nm), UV-C (200–280 nm), and far-UV (207–222 nm), are now recognized for modulating oxidative stress, restoring mitochondrial function, correcting apoptotic dysregulation, and enhancing DNA repair. Innovative approaches such as riboflavin-mediated phototherapy and photobiomodulation (PBM) show the capacity to disaggregate toxic protein aggregates like β-amyloid and α-synuclein, boost antioxidant defenses, stimulate neurotrophic factors, and quell neuroinflammation. Preclinical models and early clinical trials reveal preserved cognition, enhanced neurogenesis, and reduced disease biomarkers, suggesting real translational promise. From a public-health perspective, UV-based interventions offer a cost-effective, scalable option for aging populations and resource-limited settings, especially when integrated with community-level health technologies and remote delivery platforms. Continued investigation of optimal dosing, long-term safety, and mechanistic pathways will be pivotal to unlock the full therapeutic and population-wide impact of this novel modality.

An Analytical Method for Determining the Stress–Strain State of a Subgrade with Combined Reinforcement

Szabolcs Fischer Dmytro Kurhan Ahmad Alkhdour Oleksii Tiutkin

Publication Name: Infrastructures

Publication Date: 2024-12-01

Volume: 9

Issue: 12

Page Range: Unknown

Description:

This article presents the fundamentals of an analytical method for determining the stress–strain state of a railway subgrade reinforced with geosynthetic material. The reinforcement described is a combined system where the geosynthetic material forms an open shell containing a layer of compacted crushed stone. The overall stress–strain state is proposed to be viewed as a superposition of two states of the subgrade. The stresses and displacements in the first state refer to the unreinforced subgrade (matrix), while the stress–strain state of the reinforcement element is determined using analytical constructs from composite theory. The dependencies of the overall stress–strain state are applied in a numerical analysis, which confirms the positive effect of reduced subgrade deformations. A small-scale experimental model further validates the accuracy of the analytical approach.

Rise and fall of Stachys annua (L.) L. in the Carpathian Basin: a historical review and prospects for its revival

B. Czúcz Gyula Pinke Éva Dunai

Publication Name: Genetic Resources and Crop Evolution

Publication Date: 2021-10-01

Volume: 68

Issue: 7

Page Range: 3039-3053

Description:

Stachys annua (L.) L., a melliferous archaeophyte plant became a dominant weed of the cereal stubbles of the Carpathian Basin in the medieval three-field system. By the middle of the nineteenth century, this plant provided more than two-thirds of the Hungarian honey production, and its high quality monofloral honey turned into a characteristic brand of the Hungarian apiculture. Recognizing its importance, S. annua also briefly became a minor crop cultivated in “bee gardens” and arable fields in the late nineteenth century, possibly also in response to the first signs of its upcoming decline. Starting with the advent of the steam plough, the twentieth century has brought a drastic decline for S. annua due to a combination of deeper and earlier tillage operations, agrochemicals, and new competing weed species (in particular the common ragweed, Ambrosia artemisiifolia). The last remnant stands of this previously dominant weed species are of considerable ecological and historical value as farmland biodiversity hotspots. These sites are important refuge for rare weeds, wild pollinators (including bumblebees), and declining farmland birds, which could be targeted by eco-schemes under the European Union’s (EU’s) greening Common Agricultural Policy. The rediscovery of the cropping potential of S. annua and the development of an appropriate technology would also allow its cultivation as a valuable bee forage, catch crop, green cover, or oilseed plant in the future.

Characterization of stress serrations in AlMg alloys

Dóra Harangozó Imre Czinege

Publication Name: International Journal of Lightweight Materials and Manufacture

Publication Date: 2025-11-01

Volume: 8

Issue: 6

Page Range: 805-814

Description:

A set of parameters was developed to characterize the stress serrations produced by the Portevin-Le-Chatelier (PLC) effect, including the stress amplitudes and their frequency and time functions. In addition to the traditional Fast Fourier Transform (FFT), the Short Time Fourier Transform (STFT), which can simultaneously display the amplitude as function of time and frequency, proved to be very illustrative. This made it possible to identify type A and type B serrations, as well as their appearance in the spectrum. Based on this evaluation method, six different cold rolling and annealing variants of an AlMg3 alloy were analyzed. It was found that in the cold-formed and annealed versions of sheets an FFT amplitude peak uniformly appears at 4–10 Hz, which can be attributed to the PLC serration of type A. This peak continuously decreases in the case of the annealed sheets, while cold-formed sheet shows a new peak at approximately 18–20 Hz before the uniform strain, which indicates the appearance of type B serrations. The amplitude of stress serrations decreases with increasing yield strength, tensile strength and normal anisotropy, and increases with uniform and fracture strains and hardening exponent.
