On the Channel and Type of Aid: The Case of International Disaster Assistance [PDF]
The aim of this paper is to determine the drivers of a donor’s decision on the composition of aid. We apply a dataset on international post-disaster assistance between 2000 and 2007 that includes information on the channel (bilateral vs.

Advanced Science, EarlyView.THUMPD1 drives a tumor‐suppressive signaling cascade in lung adenocarcinoma by promoting IGF2R expression. IGF2R associates with PPP2R1A to suppress AKT and activate AMPK, leading to SLC31A1 upregulation and copper accumulation. Elevated copper disrupts mitochondrial metabolism and induces excessive mitophagy, thereby restraining tumor growth and ...

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution
Advanced Science, EarlyView.Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Aid Allocation through Various Official and Private Channels: Need, Merit and Self-Interest as Motives of German Donors [PDF]
Previous literature largely ignores the heterogeneity of aid channels used by each single donor country. We estimate Tobit models to assess the relative importance of recipient need, recipient merit and self-interest of donors for various channels of ...
