Migratory species are in rapid decline globally. Although most mortality in long-distance migrant birds is thought to occur during migration, evidence of conditions on migration affecting breeding population sizes has been completely lacking. We addressed this by tracking 42 male Common Cuckoos from the rapidly declining UK population during 56 autumn migrations in 2011-14. Uniquely, the birds ...

Amphibians are considered reliable indicators of environmental quality. In the western United States, a general decline of frog populations parallels an apparent worldwide decline. The factors thought to be contributing to declines in frog populations include habitat loss, introduction of exotic species, overexploitation, disease, climate change, and decreasing water quality. With respect to wa...

Family resources may play an important role in the wellbeing of the elderly. In this paper, we examine the association between living arrangements and cognitive decline among people over 65 in nine European countries under the hypothesis that living with others (i.e. spouse or/and children) vis –àvis living alone may have positive effects on maintaining cognitive functioning. To this end we use...

Although maternal mortality is a significant global health issue, achievements in mortality decline to date have been inadequate. A review of the interventions targeted at maternal mortality reduction demonstrates that most developing countries face tremendous challenges in the implementation of these interventions, including the availability of unreliable data and the shortage in human and fin...

Conservation biologists have only finite resources, and so must prioritise some species over others. The EDGE-listing approach ranks species according to their combined evolutionary distinctiveness and degree of threat, but ignores the uncertainty surrounding both threat and evolutionary distinctiveness. We develop a new family of measures for species, which we name EDAM, that incorporates evol...

We study the effect of hospital market concentration on the quality of patient data protection practices. We use approximately 200 reported data breaches in US hospitals over the period 2006 2011 as a measure of the quality of patient data protection practices. We measure market concentration using the Herfindahl-Hirschman Index (HHI) and estimate our models by exploiting cross-sectional HHI va...

Decline curve analysis has some advantages over transient well test analysis in which it is not required to shut-in the well and also wellbore storage effects do not exist. Few studies have been done on decline curve analysis of naturally fractured reservoirs but there are even some limitations with available models. On the other hand well test could be expensive and in some operational conditi...

We study if dynamic capabilities alleviate enterprises' revenue losses after an external shock. Contextually, we Norwegian enterprises before and the price decline of crude oil in 2014, which strongly affected economic activities across industries some regions, while others were practically unaffected. Empirically, combine data regional dependency enterprise- person-level enterprise-level reven...
