Revisiting the Growth–Forest Sustainability Nexus in India: The Role of Human Capital, Energy, and Trade

Sustainable Development, EarlyView.
ABSTRACT Understanding whether the interaction between economic activity and forest ecosystems manifests as conflict or synergy is central to designing effective, sustainable development policies. Although the environmental Kuznets curve framework is frequently utilized to explain this relationship, its analytical scope remains limited, as it ...

Governing Water Sustainability Through SDG Interlinkages: Novel Evidence on Climate Vulnerability, Health, Environmental Policy, and Clean Innovation in OECD Countries

Sustainable Development, EarlyView.
ABSTRACT Water sustainability has become a critical challenge within the sustainable development agenda, particularly under increasing climate risks and resource pressures. Despite its central role in Sustainable Development Goal 6 (SDG 6), existing studies largely adopt fragmented and linear approaches, overlooking the interconnected and nonlinear ...

Do Globalization and Clean Energy Transitions Advance Sustainable Development? Evidence on CO2 Emissions From Costa Rica

Safety Science and Technology, EarlyView.
Using annual data for Costa Rica from 1980 to 2023, this study investigates the long‐run effects of globalization, foreign direct investment (FDI), access to clean fuels and technologies for cooking, renewable energy consumption, and economic growth on CO2 emissions by employing DOLS, FMOLS, and CCR estimators.

Size multipartite Ramsey numbers for small paths versus books

Indonesian Journal of Combinatorics, 2016
Given $j \ge 2$,  for  graphs $G$ and $H$, the size Ramsey multipartite number $m_j(G, H)$ is defined as the smallest natural number $t$ such that any blue red coloring of the edges of the  graph $K_{j \times t}$, necessarily containes a red $G$ or a ...

Gameboard Ramsey Numbers

, 2005
Sequences Bn(p,q) of connected parts of Euclidean and hyperbolic (p,q)-mosaic graphs are considered. The smallest n such that any 2-coloring of the edges of Bn( p,q) contains a given monochromatic graph G is introduced as gameboard Ramsey number rp,q(G). For p ≥ 4 it is proved that these Ramsey numbers exist for finitely many graphs only.

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

Journal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

Insights from the Presidential Addresses to the Agricultural Economics Society

Journal of Agricultural Economics, EarlyView.
ABSTRACT The Society's published presidential addresses have embraced a wide range of subject matter, reflecting a ‘road well travelled’ in agricultural economics. The areas covered include the development and use of data and statistics, lessons from history, sectoral analysis, land economics, international trade and international development.

Market Integration and Nonlinear Price Transmission in 19th‐Century British Wheat Markets

Journal of Agricultural Economics, EarlyView.
ABSTRACT Important developments in infrastructure and institutions characterized 19th‐Century wheat markets in Great Britain. Among these developments was the construction of the national rail system which enabled cheaper and more efficient transport of grain and other bulky cargoes between inland towns and ports.

Ramsey Properties of Random Graphs and Folkman Numbers

Discussiones Mathematicae Graph Theory, 2017
For two graphs, G and F, and an integer r ≥ 2 we write G → (F)r if every r-coloring of the edges of G results in a monochromatic copy of F. In 1995, the first two authors established a threshold edge probability for the Ramsey property G(n, p) → (F)r ...
