Infrastructure expansion, tourism and electoral outcomes

Economica, EarlyView.
Abstract This paper examines the electoral impact of economic growth through increased foreign tourism using data from Croatia. To identify causal effects, the paper applies an instrumental variable strategy, which uses variation in the ruggedness of the local terrain to estimate the network of least‐cost paths.

An Application of the Multi-Level Heuristic for the Heterogeneous Fleet Vehicle Routing Problem [PDF]

, 2010
The Multi-Level heuristic is used to investigate the heterogeneous fleet vehicle routing problem (HFVRP). The initial solution for the Multi-Level heuristic is obtained by Dijkstra's algorithm based on a cost network constructed by the sweep algorithm ...

Multi‐objective maritime vessel routing with safety considerations

International Transactions in Operational Research, EarlyView.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Study on Near-Optimal Path Finding Strategies in a Road Network

Journal of Algorithms & Computational Technology, 2008
In this paper we analyze the existing defects of hierarchical and nonhierarchical path finding algorithm respectively in detail and present a hierarchical path finding algorithm based on the heuristic directing search approach which is used for promoting

How Context Shapes Person‐Centred Fundamental Care Through Nurse–Patient Relationships: Validation of the FoC Intelligence Modelling Tool and Predictive Pathway Analysis

Journal of Advanced Nursing, EarlyView.
ABSTRACT Background The Fundamentals of Care (FoC) Framework emphasises that care quality depends not only on clinical tasks but also on interpersonal relationships and the organisational context in which care is delivered. Although patient‐reported outcome and experience measures (PROMs and PREMs) have gained relevance in capturing these aspects ...

Increased arbuscular mycorrhizal fungal biomass and diversity in soil under long‐term climate drying and warming

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) support critical ecosystem services including plant resource acquisition and productivity. AMF functional traits such as relative biomass investment in root vs soil colonization or drought tolerance are thought to be evolutionarily conserved within AMF lineages and might influence AMF community responses to ...
