Opis: Global challenges resulting from climate change, economic distress, and social confrontation are rising. In this scenario, Social Protection (SP) provides a mechanism to deal with all such issues. This research study aims to analyse the impact of SP on Conference of the Parties (COP28) Climate Financing (CF). The study is based on a panel of 32 countries that met the CF criteria for a period of 19 years. To empirically validate the impact, the Two Step System GMM method has been used. This approach deals with the endogeneity issue and provides robust analysis to account for autocorrelation and heteroscedasticity problems. The results show that CF has a significant impact on empowering SP. However, in the case of low-income countries, the impact is negative. This paper offers a novel analysis of the COP28 CF and SP framework. The study also highlights the broader policy relevance of COP28 financing frameworks. It suggests the potential to inform global climate finance, enhance cross-country allocation, and guide the integration of climate-related funding with social protection beyond developing economies.

Opis: The circular economy (CE) has emerged as a strategic framework to decouple economic growth from environmental degradation through resource efficiency, waste reduction, and closed-loop systems. The current study uniquely integrates the PRISMA protocol with the 5W1H analytical framework and bibliometric triangulation to bridge conceptual, behavioural, and policy perspectives within CE research. This study conducts a systematic literature review of 332 peer-reviewed articles from Scopus and Web of Science, applying the PRISMA methodology and the 5W1Hb analytical framework. Bibliometric and thematic analyses reveal five core research themes: technological innovation, circular business models, policy mechanisms, behavioural insights, and supply chain optimisation. While the United Kingdom and India lead in scholarly and policy contributions,the CE research landscape remains fragmented. Key gaps persist in digital nudging, behavioural adoption, and sector-specific applications. The study emphasises the need for interdisciplinary approaches and model-driven frameworks to foster systemic CE transitions. By mapping conceptual trends, theoretical linkages, and regional participation, this study provides a novel integrative synthesis and actionable implications for policymakers, researchers, and practitioners seeking to accelerate CE adoption.

Opis: This study examines the impact of the business environment on foreign direct investment (FDI) inflows into Africa, utilising panel data from 39 African countries over the period 2005–2019. Institutional and regulatory dimensions are captured through selected indicators from the World Bank’s Ease of Doing Business Index. A dynamic panel data approach is employed, applying the one-step difference Generalised Method of Moments (GMM) estimator to address potential endogeneity, autocorrelation,  and unobserved heterogeneity. The results indicate strong persistence in FDI, with lagged inflows exerting a significant positive effect on current levels. Among the business environment indicators, registering property is positively and significantly associated with FDI, highlighting the importance of secure property rights. Conversely, getting credit shows a significant negative relationship, suggesting that inefficiencies in credit markets may deter investment. These findings underscore the need for policy reforms aimed at streamlining property registration and enhancing credit market infrastructure to foster a more conducive environment for sustained FDI inflows and economic development.

Opis: We continue the study of (tw, ω)‐bounded graph classes, that is, hereditary graph classes in which large treewidth is witnessed by the presence of a large clique, and the relation of this property to boundedness of the tree‐independence number, a graph parameter introduced independently by Yolov in 2018 and by Dallard, Milanič, and Štorgel in 2024. Dallard et al. showed that bounded tree‐independence number is sufficient for (tw, ω)‐boundedness, and conjectured that the converse holds. While this conjecture has been recently disproved, it is still interesting to determine classes where the conjecture holds; for example, the conjecture is still open for graph classes excluding an induced star, as well as for finitely many forbidden induced subgraphs. In this paper, we identify further families of graph classes where (tw, ω)‐boundedness is equivalent to bounded tree‐independence number. We settle a number of cases of finitely many forbidden induced subgraphs, obtain several equivalent characterizations of (tw, ω)-boundedness in subclasses of the class of complements of line graphs, and give a short proof of a recent result of Ahn, Gollin, Huynh, and Kwon [SODA 2025] establishing bounded tree-independence number for graphs excluding a fixed induced star and a fixed number of independent cycles.

Opis: Wildlife monitoring is crucial for successful conservation and management of wildlife populations. To support modern wildlife monitoring approaches in Slovenia, we developed SRNA, a nationwide citizen science appli- cation that collects additional metadata on several terrestrial vertebrate species. The app is designed for two groups of citizen scientists, hunters and other nature observers. To foster learning, it features a photo-based wildlife identification quiz and species identification guides. This pilot study evaluated app use and data quality with two aims: (1) to assess users’ ability to identify wildlife species from photos, focusing on taxa expected to be challenging to identify, and to test whether identification accuracy varies across mammal groups; (2) to analyse wildlife observation data submitted through SRNA. Users were successful in identifying several distinctive species but had some difficulty distinguishing between certain mustelids, and between golden jackal and grey wolf, indicating priorities for targeted educational campaigns. Biology-related educational background facilitated identification of mustelids and, to a lesser extent, canids. In its first year, SRNA collected 1633 observations via 742 reports, predominantly of European roe deer. Hunters and nature observers contributed complementary data: differences were observed not only in the number of reported species and amount of data they provided, but also in reporting patterns across biogeo- graphic regions, reporting rates, and the average delay time between encounters and submissions. This study demonstrates that SRNA provides promising complementary data for wildlife monitoring, but also highlights data quality limitations (biases and verification issues) that must be taken into account when using SRNA data.
