We tested whether routes of raptors migrating over areas with homogeneous topography follow constant geomagnetic courses more or less closely than constant geographical courses. We analysed the routes taken over land of 45 individual raptors tracked by satellite-based radiotelemetry: 25 peregrine falcons, Falco peregrinus, on autumn migration between North and South America, and seven honey buzzar
Physical exercise has been suggested to reduce the risk of developing Alzheimer’s disease (AD) as well as ameliorate the progression of the disease. However, we recently published results from two large epidemiological studies showing no such beneficial effects on the development of AD. In addition, long-term, voluntary running in the 5xFAD mouse model of AD did not affect levels of soluble amyloi
Increases in the size of agricultural fields, the loss of permanent green field edges and other semi-natural habitats have accompanied the intensification of agriculture, and are still ongoing. From a farm economic perspective, an increase in field size increases efficiency mainly due to cost savings. However, recent evidence suggests that increases in field size might lead to the loss of ecosyste
Global warming and more frequent climate extremes have caused bark beetle outbreaks of unprecedented scale of these insects in many conifer forests world-wide. Conifers that have been weakened by drought and heat or damaged by storms are highly susceptible to bark beetle infestation. A large proportion of trees with impaired defences provides good conditions for beetle population build-up of beetl
This paper navigates the subject of economic growth and energy use, with a focus on environmental sustainability. The aim is to investigate the relationship between the renewable share of total primary energy supply and the GDP per capita growth rate by conducting an empirical study on the OECD member states. The growth rate of GDP has for a long time been used as a measure of economic growth and
The study asks what role Karl Marx’s theory of the law of the tendency of the rate of profit to fall has in explaining transformation, crises and secular stagnation in Sweden. Support is presented for the “law”, with Sweden exhibiting a long-term secular decline in the rate of profit throughout the late 19th and 20th century. For the period 1950-2016, there is a strong tendency towards “Marx-biase
Single-crystal neutron diffraction reveals two distinct components to the magnetic ordering in geometrically frustrated SrEr2O4. One component is a long-range ordered k = 0 structure which appears below T-N = 0.75 K. Another component is a short-range incommensurate structure which manifests itself by the presence of a strong diffuse scattering signal. On cooling from higher temperatures down to 0
Memory competition often hinders the retrieval of a particular event. It has long been established that access to the encoding context facilitates later retrieval. Previous research suggested that context is encoded alongside with event memories like bookmarks and can be used to differentiate target memory from competitors. The current study used pupillometry to investigate if context mitigates me
The objective of this article is to study the links between the financing of primary education, schooling and economic growth in France in the nineteenth century. To do so, we use information on the financing allocated by the State, the departments, the municipalities, and households over the period 1820–1913. Our analysis is in two stages. First, we analyse the evolution of these different types
This study examines the underlying patterns of savings and investments in China for the period 1978 – 2008. The institutional changes that occurred as a result of the 1978 economic reforms programme brought about profound changes to the characteristics of savings and investments in China. The paper finds that household savings while high, do not explain China’s high savings rate as a whole. High s
It is well known that (some speakers of) Norwegian allow long distance binding, defined here as binding across a finite clause boundary. A number of factors that facilitate long distance binding have also been identified. In the study reported on here, 93 native speakers of Norwegian judged 30 sentences in a web-based questionnaire. The results show that V2 order in the embedded clause reduces the
This article examines whether there exists any causal relationship between foreign trade and declining pollution in developed countries. In other words, do developed countries outsource their problems to less developed countries rather than solve them? The case study is the Swedish economy and the two environmental indicators employed are energy consumption and CO2 emissions. No causal relationshi
Safety is one of the key issues preventing the deployment of reinforcement learning techniques in real-world robots. While most approaches in the Safe Reinforcement Learning area do not require prior knowledge of constraints and robot kinematics and rely solely on data, it is often difficult to deploy them in complex real-world settings. Instead, model-based approaches that incorporate prior knowl
This paper examines the role of foreign trade in the consumption of energy in Czechoslovakia through a bottom-up approach in accounting for energy embodied in trade with manufactured goods. It provides a unique analysis of annual changes in energy embodied in trade in a country characterized by changing political regimes. On the whole, Czechoslovakia has been a net exporter of energy throughout th
Traumatic brain injury (TBI) is the leading cause of death and disability in young adults. Survivors of TBI frequently suffer from long-term personality changes and deficits in cognitive and motor performance, urgently calling for novel pharmacological treatment options. To date, all clinical trials evaluating neuroprotective compounds have failed in demonstrating clinical efficacy in cohorts of s
In this paper we examine health among breast cancer 5-year survivors. We raise two questions: (1) how do the health level of this survival group compare to the health level of the general population; and (2) how have the health levels among these survivors changed over time. We found that 5-year breast cancer survivors assess their health lower than the general population, and that having being di
