Background: Climate change poses an escalating threat to global brain health and is increasingly linked to stroke incidence, outcomes, and inequities in prevention and treatment. This World Stroke Organization scientific statement summarizes current evidence on the associations between stroke and the environmental variables exacerbated by climate change, with a focus on risk and outcomes. Methods:
Entrepreneurship is an emerging research field that has received much scholarly attention in recent decades. Given the global scope of this attention, this article compares entrepreneurship research in China with that in the USA and Europe. Based on publications in Social Science Citation Index and Chinese Social Science Citation Index databases over the past 10 years, we use bibliometric method t
We hypothesize that cerebral ischemia leads to enhanced expression of endothelin (ET), 5-hydroxytryptamine (5-HT), and angiotensin II (ANG II) receptors in the vascular smooth muscle cells. Our aim is to correlate the upregulation of cerebrovascular receptors and the underlying molecular mechanisms with the reduction in regional and global cerebral blood flow (CBF) after subarachnoid hemorrhage (S
Mild cognitive impairment in Parkinson's disease is associated with progression to dementia (Parkinson's disease dementia) in a majority of patients. Determining structural imaging biomarkers associated with prodromal Parkinson's disease dementia may allow for the earlier identification of those at risk, and allow for targeted disease modifying therapies. One hundred and five non-demented subjects
Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in
With Paul Wolfowitz now heading the World Bank, fighting corruption has become a top priority, with the Bank actually holding back funds to various countries due to corruption. USAID has also allocated hundreds of millions of dollars to anticorruption and governance. At the same time, there exist grassroots anticorruption initiatives, many of whom are linked to the international NGO Transparency I
To enter new markets is not easy. The most obvious challenge, at least judging from the majority of literature on internationalization, is to understand the new market thus taking a market(ing) perspective. External aspects of internationalization are often stressed, while internal aspects, focusing on why organizations fail, are less developed or examined. In order to better understand the intern
Popular Abstract in Swedish Ett material som utsätts för varierande last, även under gränslasten för statisk kollaps, riskerar att utveckla sprickor som i sin tur kan orsaka brott. Denna typ av materialnedbrytning kallas utmattning och är ett ständigt aktuellt forskningsområde. Väldigt korta sprickor är kända för att växa på ett sätt som avviker från hur längre utmattningssprickor beter sig, ävenThe growth of short fatigue cracks deviates from the behaviour of long fatigue cracks even if subjected to the same nominal driving force. The influence from the microstructure is pronounced, while crack closure effects may not be that important as for longer cracks. The objective of this thesis is to study the local conditions for crack growth for two different short crack problems, and to develo
We study transportation networks controlled by dynamical feedback tolls. We consider a multiscale transportation network model whereby the dynamics of the traffic flows are intertwined with those of the drivers' route choices. The latter are influenced by the congestion status on the whole network as well as dynamic tolls set by the system operator. Our main result shows that a broad class of dece
Study region: The Tibetan Plateau (TP) is a high-altitude region characterized by harsh environmental conditions and limited accessibility, making the monitoring of its numerous lakes a significant challenge. This region is crucial for hydrological studies, and its numerous lakes play an important role in regional water dynamics and climate change research. Study focus: This study evaluates the ap
National greenhouse gas inventories (GHGIs) are submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC). They are estimated in compliance with Intergovernmental Panel on Climate Change (IPCC) methodological guidance using activity data, emission factors and facility-level measurements. For some sources, the outputs from these calculations are very uncertain. Invers
Climate change has diverse effects on the planet’s environment, including changes and shifts in the distribution and abundance of species. In this paper, we present a robust prediction ensemble algorithm for the current and future species distribution of Aegilops tauschii. Four modeling approaches were trained using various environmental variables (bioclimatic and soil variables) to accurately pre
The purpose of this thesis is to examine the United States’ influence on the international community’s ability to prohibit the Rwandan genocide of 1994. Over the course of 100 days government forces and Hutu militia implemented an elimination campaign with the main objective of ethnically cleansing Rwanda of the Tutsi minority, and effectively slaughtered 800,000 civilians. By rhetorically analyzi
The European Union aims at being an ethical actor on the global arena and the EU development-policy is directed towards achieving long-term socio-economic development, with a specific focus on Sub-Saharan Africa, where development is showing little progress, and food security and agricultural development is at the top of the agenda. The EU is both the biggest market and the biggest aid-donor for
