Apparent competition is an indirect interaction between 2 or more prey species through a shared predator, and it is increasingly recognized as a mechanism of the decline and extinction of many species. Through case studies, we evaluated the effectiveness of 4 management strategies for species affected by apparent competition: predator control, reduction in the abundances of alternate prey, simu...

This paper analyses the determinants of broadband Internet access prices in a group of 15 EU countries between 2008 and 2011. Using a rich panel dataset of broadband plans, we show the positive effect of downstream speed on prices, and report that cable and fibre-to-the-home technologies are available at lower prices per Mbps than xDSL technology. Operators’ marketing strategies are also analys...

For many firms, the ability to capture and maintain market share and profitability on the Internet is dependent on a firm’s ability to create and maintain a closed competition system (CCS) – that is, a system of business operation with customers that competitors can neither enter nor emulate very effectively. A CCS can be created through market, technological, or policy means. Sometimes these d...

Tolerance implies enduring trying circumstances with a fair and objective attitude. To determine whether evolutionary advantagesmight be stemming fromdiverse levels of tolerance in a population, we study a spatial public goods game, where in addition to cooperators, defectors, and loners, tolerant players are also present. Depending on the number of defectors within a group, a tolerant player c...

The aim of the present study was to verify, during a stressful sport competition, the associations between motivational antecedents and consequences of the coping process. Using a two-wave design, we tested a model that incorporates motivational orientations, coping dimensions, goal attainment, and affective states among athletes (N = 122). Path analyses using EQS revealed that selfdeterminatio...

We hypothesized that dinitrogen (N2 )- and non-N2 -fixing tropical trees would have distinct phosphorus (P) acquisition strategies allowing them to exploit different P sources, reducing competition. We measured root phosphatase activity and arbuscular mycorrhizal (AM) colonization among two N2 - and two non-N2 -fixing seedlings, and grew them alone and in competition with different inorganic an...

We provide a comprehensive analysis of capacity investment decisions in duopoly models with demand uncertainty. Firms make capacity investment, production, delivery and pricing decisions. Capacity investment decisions are always made ex-ante demand whereas price decisions always ex-post. The interplay between the timing of demand information and the decision of production and delivery endows fi...

Motivated by the recent backshoring trend, this paper studies a sourcing game where competing firms may choose between efficient sourcing (e.g., sourcing from overseas) and responsive sourcing (e.g., sourcing from home country). Efficient sourcing usually provides a cost advantage, while responsive sourcing allows a firm to obtain more accurate demand information when making procurement decisio...

Over the past two and a half decades, a remarkable series of tools, technologies, and techniques have been created, developed, and refined for the performance of percutaneous coronary intervention (PCI). A constant over time, however, has been the therapeutic framework of enlargement of the luminal dimensions of diseased coronary vessels as the hallmark of PCI. Within this construct, an obligat...
